Chronic pelvic pain (CPP) has an annual prevalence of 38/1000 in the UK, with coexisting pathologies often present. Diagnostic laparoscopy has long been the gold standard diagnostic test, but with up to 40% showing no abnormality, we explore the value of noninvasive imaging, such as pelvic ultrasound and MRI. A literature review from inception until January 2015 of the following databases: PubMed, MEDLINE, Cumulative Index to Nursing and Allied Health Literature, Excerpta Medica database, and System for Information on Grey Literature in Europe were performed to identify published studies assessing the usefulness of ultrasound, MRI, and laparoscopy in the diagnosis of CPP. Three studies (194 women) addressed their comparative performance in patients with endometriosis, showing the sensitivity of ultrasound ranged between 58 and 88.5%; MRI was 56-91.5% and in the one study using histology as its reference standard, the sensitivity of laparoscopy was 85.7%. Noninvasive imaging has the additional benefit of being well tolerated, safer, and cheaper than surgery. CPP, by nature of its multifactorial causation, can be difficult to manage and often requires a multidisciplinary team. Ultrasound and MRI may provide information about the presence or lack of abnormality, which would allow general practitioners or office gynaecologists to initiate treatment and think about surgery as a second-line investigative tool.

Background: Despite dynamic development of diagnostic imaging methods and endoscopic procedures, X-ray hysterosalpingography remains the basic diagnostic procedure when anatomical cause of infertility is suspected. The aim of the study was to assess the correlation between HSG results and laparoscopy findings, especially in infertile women with normal results of hysterosalpingography. Material/Methods: The results of HSG and laparoscopies performed between 2002 and 2005 years in 53 infertile women were analyzed retrospectively. The indication for HSG was primary infertility in 44 cases and secondary infertility in 9 cases.Results: The result of HSG was normal in 51%. Pathological findings were observed in 49% of HSG and in 93% of laparoscopies. The most common pathological findings observed during laparoscopy were tubal occlusion (26% cases) and endometriosis (25% cases). Polycystic ovaries and myomas were observed in 20% of the performed laparoscopies. HSG and laparoscopy yield consistent results in evaluation of tubal patency (p < 0.001). Conclusions: HSG remains the method of first choice in the diagnostics of uterine malformations and tubal diseases as causes of infertility. When mechanical factors of female infertility are suspected, HSG allows the optimal choice of more invasive procedure. (authors)

OBJECTIVE To evaluate the feasibility of laparoscopy versus exploratory laparotomy for the diagnosis of specific lesions in dogs with suspected gastrointestinal obstruction. DESIGN Controlled trial. ANIMALS 16 client-owned dogs with physical and radiographic findings consistent with gastrointestinal obstruction. PROCEDURES Single-incision laparoscopy with intracorporeal and extracorporeal examination of the gastrointestinal tract was performed by 1 surgeon. Immediately afterward, exploratory laparotomy was performed by a second surgeon. Accessibility and gross appearance of organs, surgical diagnoses, incision lengths, procedure duration, and complications were compared between diagnostic techniques. RESULTS Mean (95% confidence interval) incision length was 4.9 cm (3.9 to 5.9 cm) for laparoscopy and 16.4 cm (14.0 to 18.7 cm) for exploratory laparotomy. Mean (95% confidence interval) procedure duration was 36.8 minutes (31.6 to 41.2 minutes) and 12.8 minutes (11.4 to 14.3 minutes), respectively. Diagnoses of the cause of obstruction were the same with both methods. In 13 dogs, the laparoscopic examination was successfully completed, and in the other 3, it was incomplete. In 4 dogs in which laparoscopy was successful, conversion to exploratory laparotomy or considerable extension of the laparoscopic incision would have been required to allow subsequent surgical treatment of identified lesions. No dogs developed major complications, and minor complication rates were similar between procedures. CONCLUSIONS AND CLINICAL RELEVANCE Laparoscopy was feasible and clinically applicable in dogs with suspected gastrointestinal obstruction. Careful patient selection and liberal criteria for conversion to an open surgical approach are recommended when laparoscopy is considered for the diagnosis of gastrointestinal lesions in dogs.

Hysterectomy and laparoscopy are the two most common surgical options used to treat women with endometriosis, yet the disease may still recur. This study aimed to determine the long-term retreatment rates among endometriosis patients in the United States who received either hysterectomy or laparoscopy. Patients aged 18-49 years with endometriosis who underwent hysterectomy or laparoscopy were identified in the Truven Health MarketScan claims database (2004-2013). The retreatment rate up to 8 years after the initial surgery was estimated using Kaplan-Meier survival analysis. The relative risk of retreatment among patients with hysterectomy versus laparoscopy was assessed using a Cox proportional hazard model. A total of 24,915 patients with endometriosis who underwent hysterectomy and 37,308 patients with endometriosis who underwent laparoscopy were identified. The estimated retreatment rates were 3.3%, 4.7%, and 5.4% in the 2nd, 5th, and 8th year following hysterectomy, respectively, while the rates following laparoscopy were 15.8%, 27.5%, and 35.2%, respectively. The hazard ratio of retreatment was 0.157 (95% confidence interval [CI]: 0.146-0.169) comparing hysterectomy to laparoscopy. In the sensitivity analysis, which expanded the definition of retreatment by including medical treatments, the retreatment rate increased by a factor of 11-14 for the hysterectomy cohort and by a factor of 2-4 for the laparoscopy cohort, and the hazard ratio of retreatment rate for hysterectomy versus laparoscopy was 0.490 (95% CI: 0.477-0.502). Our study results indicated that the disease retreatment rate after laparoscopy is high among patients with endometriosis; even hysterectomy does not guarantee freedom from retreatment.

Objective: To evaluate the diagnostic efficacy of laparoscopy in ill-defined recurrent chronic abdominal pain. Study Design: Prospective study. Place and Duration of Study: Surgical department, Military Hospital Rawalpindi, from Jul 2011 to Dec 2013. Material and Methods: A total of 102 patients who presented to surgical department with chronic recurrent abdominal pain of unknown etiology and underwent diagnostic laparoscopy were included in our study. Patients with acute onset of abdominal pain, hemodynamically unstable, pregnant or those in which diagnosis can be made by radiological techniques were excluded from our study. Patient's demographic data, clinical findings and laparoscopic findings were recorded. Finally data was analyzed by using SPSS version 21. Results: Out of 110 patients 96 were female while remaining 14 were male. The age range of the patients was 20- 70 years with mean age of 50 +- 10 years. The most common site of pain was lower abdomen while mean duration of abdominal pain was 34 weeks. Laparoscopic findings include acute recurrent appendicitis in 32 (29.09%) patients, cholecystitis with biliary sludge in 14 (12.72%), pelvic inflammatory disease in 12 (10.90%), ovarian cyst in 11(10%), adhesions in 10(9.09%), intestinal tuberculosis in 8 (7.27%), mesenteric lymphadenitis in 7 (6.36%), lymphoma in 4 (3.63%), ectopic pregnancy in 3 (2.7%), CA gallbladder in 2 (1.81%), meckels diverticulum in 2 (1.81%), endometriosis in 2 (1.81%) and crohns disease in 1 (0.9%) patients. Mean operative time was 48 min while average hospital stay was 2-3 days. No major complications were noticed. Conclusion: Laparoscopy in our clinical setup has significant role in diagnosing cases of vague abdominal pain which cannot be diagnosed by routine investigations. (author)

Enthusiasm for the use of laparoscopy in trauma has not rivaled that for general surgery. The purpose of this study was to evaluate our experience with laparoscopy at a level II trauma center. A retrospective review of all trauma patients undergoing diagnostic or therapeutic laparoscopy was performed from January 2004 to July 2010. Laparoscopy was performed in 16 patients during the study period. The average age was 35 years. Injuries included left diaphragm in 4 patients, mesenteric injury in 2, and vaginal laceration, liver laceration, small bowel injury, renal laceration, urethral/pelvic, and colon injury in 1 patient each. Diagnostic laparoscopy was performed in 11 patients (69%) with 3 patients requiring conversion to an open procedure. Successful therapeutic laparoscopy was performed in 5 patients for repair of isolated diaphragm injuries (2), a small bowel injury, a colon injury, and placement of a suprapubic bladder catheter. Average length of stay was 5.6 days (range, 0 to 23), and 75% of patients were discharged home. Morbidity rate was 13% with no mortalities or missed injuries. Laparoscopy is a seldom-used modality at our trauma center; however, it may play a role in a select subset of patients.

Full Text Available OBJECTIVES: With normal hysterosalpingography (HSG results, selecting suitable candidates for the laparoscopic treatment of probable pelvic adhesions following previous pelvic inflammatory disease, it would be wise to investigate serum antibody screening against chlamidia trachomatis. It is worth to evaluate whether it is useful to detect a negative antichlamidial antibody disease for cancelling laparoscopy for a while with abnormal HSG findings. These two subjects have been investigated in study. MATERIAL AND METHODS: For detecting diagnostic value of serum antichlamidial antibody, in our infertility clinic, postoperative blood samples of 80 patients who were hospitalized for diagnostic laparoscopy to investigate infertility ethiology between May 2004 and November 2005 have been tested with microelisa method for antichlamidial IgM and IgG antibodies. HSG films of the patients performed at least one year were evaluated. Venous blood was drawn from these patients during postoperative early period for studying serum IgM and IgG antibodies of chlamidia trachomatis and the results were compared with operative findings. RESULTS: According to the antichlamidial antibody levels 60 (75% patients have not been infected with chlamidia and 20 (25% patients have been infected previously. When the patients were divided to two groups; normal and abnormal; based on preoperative HSG films; 18 (30% of the 60 patients with abnormal HSG films and 2 (10% of the 20 patients with normal HSG films had positive antichlamidial antibody levels respectively. CONCLUSION: The relationship between chlamidia trachomatis infection and tubal infertility has been demonstrated among 85% of patients with positive antichlamidial antibody levels and 46.7% of patients with negative levels who had tubal passage defects detected during diagnostic laparoscopy.

BACKGROUND & AIMS Observational studies and small randomized controlled trials have shown that the use of laparoscopy in colon resection for diverticular disease is feasible and results in fewer complications. We analyzed data from a large, prospectively maintained, multicenter database (National Surgical Quality Initiative Program) to determine whether the use of laparoscopy in the elective treatment of diverticular disease decreases rates of complications compared with open surgery, independent of preoperative comorbid factors. METHODS The analysis included data from 6970 patients who underwent elective surgeries for diverticular disease from 2005 to 2008. Patients with diverticular disease were identified by International Classification of Diseases, 9th revision codes and then categorized into open or laparoscopic groups based on Current Procedural Terminology codes. Preoperative, intraoperative, and postoperative data were analyzed to determine factors associated with increased risk for postoperative complications. RESULTS Data were analyzed from 3468 patients who underwent open surgery and 3502 patients who underwent laparoscopic procedures. After correcting for probability of morbidity, American Society of Anesthesiology class, and ostomy creation, overall complications (including superficial surgical site infections, deep incisional surgical site infections, sepsis, and septic shock) occurred with significantly lower incidence among patients who underwent laparoscopic procedures compared with those who received open operations. CONCLUSIONS The use of laparoscopy for treating diverticular disease, in the absence of absolute contraindications, results in fewer postoperative complications compared with open surgery.

Internal herniations through broad ligament defects are very rare. We present the first report of the triad of broad ligament defect, internal herniation of the caecum and appendicitis. A 36-year-old woman with phocomelia presented with right iliac fossa pain and vomiting. The patient had no previous history of trauma or surgery. Abdominal ultrasound showed a small amount of free fluid. At laparoscopy, bilateral broad ligament defects were found, with herniation of the caecum and an inflamed appendix through the right-sided defect. A laparoscopic salpingo-oophorectomy was required for reduction of the herniated bowel, and an appendicectomy was performed. Broad ligament defects may be congenital or acquired. In this case, in light of the limb abnormality and absence of previous surgery, a congenital aetiology is more likely. Ultrasound scan is not reliable and, although computed tomography may be of help, a diagnostic laparoscopy is the best investigation. PMID:20566032

To compare the rates of intraoperative and postoperative complications of robotic surgery and laparoscopy in the surgical treatment of endometrial cancer. Unicentric retrospective study (Canadian Task Force classification II-2). Tertiary teaching hospital. The study was performed from January 2002 to December 2011 and included patients with endometrial cancer who underwent laparoscopic or robotically assisted laparoscopic surgical treatment. Data collected included preoperative data, tumor characteristics, intraoperative data (route of surgery, surgical procedures, and complications), and postoperative data (early and late complications according to the Clavien-Dindo classification, and length of hospital stay). Morbidity was compared between the 2 groups. The study included 146 patients, of whom 106 underwent laparoscopy and 40 underwent robotically assisted surgery. The 2 groups were comparable in terms of demographic and preoperative data. Intraoperative complications occurred in 9.4% of patients who underwent laparoscopy and in none who underwent robotically assisted surgery (p = .06). There was no difference between the 2 groups in terms of postoperative events. Robotically assisted surgery is not associated with a significant difference in intraoperative and postoperative complications, even when there were no intraoperative complications of robotically assisted surgery.

Laparoscopy is increasingly utilised as a diagnostic tool in management of abdominal trauma; however its role in therapeutic intervention remains unexplored. The aim of this study is to compare laparoscopy with laparotomy in the treatment of abdominal trauma in haemodynamically stable patients. A review of patients undergoing surgery for abdominal trauma between January 2004-2014 identified 25 patients who underwent laparoscopy for therapeutic intervention (TL). This group was matched with 25 similar patients undergoing laparotomy (LT). Matching of the two cohorts was based on patient characteristics, severity of injuries, haemodynamic compromise and radiological findings. Peri-operative outcomes were compared. Patient characteristics were similar in TL and LT patients for age (median 33 vs. 26 years), gender distribution and clinical presentation. Injury severity score was also similar with a median of 16 in both groups (major trauma = ISS>15, normal range 0-75). Types of injuries included; hollow viscus [bowel repair = 10 (TL) vs. 16 (LT)] and solid organs [5(TL) vs. 2 (LT)]. Median operating time was similar in both groups; 105(TL) compared to 98 (LT) minutes. Post-operative complications (1 vs. 10, p = 0.02), analgesia requirements, specifically opiate use (34 vs. 136 morphine equivalents, p = 0.002) and hospital stay (4 vs. 9 days, p = 0.03) were significantly lower in the laparoscopy group. Abdominal trauma in haemodynamically stable patients can be managed effectively and safely with laparoscopy by experienced surgeons. Major benefits may include lower morbidity, reduced pain, and shorter length of hospital stay. Crown Copyright © 2017. Published by Elsevier Ltd. All rights reserved.

Hysterectomy and laparoscopy are common surgical procedures used for the treatment of endometriosis. This study compares outcomes for women who received either procedure within the first year post initial surgery. The study used data from the Truven Health MarketScan claims databases from 2004 to 2013 to identify women aged 18-49 years who received an endometriosis-related laparoscopy or hysterectomy. Patients were excluded if they did not have continuous insurance coverage from 1 year before through 1 year after their endometriosis-related procedure, if they were diagnosed with uterine fibroids prior to or on the date of surgery (i.e., index date), or if they had a hysterectomy prior to the index date. The descriptive analyses examined differences between patients with an endometriosis-related laparoscopy or hysterectomy in regard to medications prescribed, complications, and hospitalizations during the immediate year post procedure. The final sample consisted of 24,915 women who underwent a hysterectomy and 37,308 who underwent a laparoscopy. Results revealed significant differences between the cohorts, with women who received a laparoscopy more likely to be prescribed a GnRH agonist, progestin, danazol, or an opioid analgesic in the immediate year post procedure compared to women who underwent a hysterectomy. In contrast, women who underwent a hysterectomy generally had higher complication rates. Index hospitalization rates and length of stay (LOS) were higher for women who had a hysterectomy, while post-index hospitalization rates and LOS were higher for women who had a laparoscopy. For both cohorts, post-procedure complications were associated with significantly higher hospitalization rates and longer LOS. This study indicated significantly different 1-year post-surgical outcomes for patients who underwent an endometriosis-related hysterectomy relative to a laparoscopy. Furthermore, the endometriosis patients in this analysis had a considerable risk of

To investigate the clinical advantages of the stent-laparoscopy approach to treat colorectal cancer (CRC) patients with acute colorectal obstruction (ACO). From April 2008 to April 2012, surgery-related parameters, complications, overall survival (OS), and disease-free survival (DFS) of 74 consecutive patients with left-sided CRC presented with ACO who underwent self-expandable metallic stent (SEMS) placement followed by one-stage open (n = 58) or laparoscopic resection (n = 16) were evaluated retrospectively. The stent-laparoscopy group was also compared with a control group of 96 CRC patients who underwent regular laparoscopy without ACO between January 2010 and December 2011 to explore whether SEMS placement influenced the laparoscopic procedure or reduced long-term survival by influencing CRC oncological characteristics. The characteristics of patients among these groups were comparable. The rate of conversion to open surgery was 12.5% in the stent-laparoscopy group. Bowel function recovery and postoperative hospital stay were significantly shorter (3.3 ± 0.9 d vs 4.2 ± 1.5 d and 6.7 ± 1.1 d vs 9.5 ± 6.7 d, P = 0.016 and P = 0.005), and surgical time was significantly longer (152.1 ± 44.4 min vs 127.4 ± 38.4 min, P = 0.045) in the stent-laparoscopy group than in the stent-open group. Surgery-related complications and the rate of admission to the intensive care unit were lower in the stent-laparoscopy group. There were no significant differences in the interval between stenting and surgery, intraoperative blood loss, OS, and DFS between the two stent groups. Compared with those in the stent-laparoscopy group, all surgery-related parameters, complications, OS, and DFS in the control group were comparable. The stent-laparoscopy approach is a feasible, rapid, and minimally invasive option for patients with ACO caused by left-sided CRC and can achieve a favorable long-term prognosis.

During the period from 1968--1977 2400 laparoscopies were performed. Of these 10.7% were for diagnostic purposes only, in 3.6% of the cases laparoscopy was combined with biopsie and in 85.7% with tubal sterilization. Deaths or serious bleedings did not occur, laparotomies were not necessary. Total insignificant complications amounted to 1.6% (1.3% small bleedings which did not necessitate an operation and in 0.3% clinical signs of peritonitis, these disappeared after 3 to 15 days). In 0.7% laparoscopy was interrupted because of poor vision. Nine of 2055 women became pregnant after sterilization (4.5 pregnancies/1000 sterilizations). In 2 cases the ligamentum rotundum was coagulated, in 7 cases recanalization was histologically confirmed. Until Oct. 1975 coagulation was unipolar, afterwords bipolar. In 45.3% the patients had undergone an operation before, like Ceasarian section, gallbladder operation, appendectomy or umbilical hernia operation. Patients with longitudinal incision, with preceding peritonitis or ileus were excluded from laparoscopy. Laparoscopy was performed by all assistents during their last year of clinical instruction. Their first 30 laparoscopies were done under control, every assistent performed about 100 laparoscopies.

Full Text Available Objective: To determine the role of diagnostic hysterolaparoscopy in the evaluation of infertility in tertiary care centres. Materials and Methods: This retrospective study was conducted at two tertiary care centres (the infertility clinics of Sriram Chandra Bhanj Medical College and Prachi hospital at Cuttack, Odisha throughout the year in 2008. Women aged 20-40 years with normal hormone profile without male factor infertility were included. Results: Out of 300 cases, 206 (69% patients had primary infertility. While laparoscopy detected abnormalities in 34% of the cases, significant hysteroscopy findings were noted in 18% of cases. Together, diagnostic hysterolaparoscopy detected abnormalities in 26% of the infertile patients in both groups. While the most common laparoscopic abnormality was endometriosis (14% and adnexal adhesion (12% in primary and secondary infertile patients, respectively, hysteroscopy found intrauterine septum as the most common abnormality in both groups. Conclusions: Hysterolaparoscopy is an effective diagnostic tool for evaluation of certain significant and correctable tubo-peritoneal and intrauterine pathologies like peritoneal endometriosis, adnexal adhesions, and subseptate uterus, which are usually missed by other imaging modalities.

2017-01-01

Ovarian ectopic pregnancies are a rare occurrence; however the incidence is on the rise. Preoperative diagnosis remains difficult due to nonspecific clinical symptoms and USS findings. Most patients undergo diagnostic laparoscopy with subsequent surgical management. We present the case of a 32-year-old female who presented with vaginal bleeding and an unsited pregnancy, with a BhCG of 24693. Formal USS described unruptured right tubal ectopic with ovarian pregnancy being diagnosed at laparoscopy. A wedge resection was conducted to preserve ovarian function. Postoperative recovery was uneventful and BhCG levels returned to zero (nonpregnant) in an outpatient setting. Although laparoscopy remains the gold standard of diagnosis and treatment, in this case report we discuss benefits of early diagnosis for fertility conserving management, including nonsurgical options.

Laparoscopy in the acute abdomen.

Navez, Benoit; Navez, Julie

2014-02-01

Laparoscopy has become a routine procedure in the management of acute abdominal disease and can be considered both an excellent therapeutic and additional diagnostic tool in selected cases. However, a high level of expertise in laparoscopic and emergency surgery is required. Hemodynamic instability, huge abdominal distension, fecal peritonitis and perforated cancer are relative contraindications for the laparoscopic approach. In recent years, abdominal emergencies have increasingly been managed successfully by laparoscopy. In acute appendicitis, acute cholecystitis and perforated peptic ulcer, randomized controlled trials have proven that the laparoscopic approach is as safe and as effective as open surgery, with fewer complications and a quicker postoperative recovery. Other indications such as blunt and penetrating trauma to the abdomen, small bowel occlusion and perforated diverticular disease are under debate, indicating that more randomized controlled trials comparing laparoscopic and open surgery are still necessary.

Objective: To describe the results of laparoscopic procedures at a Urology - Nephrology tertiary care centre. Study Design: Case series / observational study. Place and Duration of Study: The Kidney Centre Postgraduate Training Institute, Karachi, from August 2007 to March 2012. Methodology: Medical records of all planned laparoscopic surgery conducted during the study period were reviewed. Those cases which to open surgery were excluded. All were performed by a single surgeon, initially as supervised and later independently. Data was maintained for demographic data, procedure details, length of hospital stay, and complications including conversion to open surgeries. Data was analyzed through SPSS 17.0. Results: There were 36 planned laparoscopic surgeries in the specified period. Out of 36 cases, 8 were converted to open surgery. Those who underwent laparoscopic surgery include two diagnostic procedures and renal cyst deroofing each, four ureterolithotomy, nineteen simple nephrectomy and one radical nephrectomy. So in total 28 cases were performed on 15 females and 13 males with mean age of 33.01 A +- 10.9 years. The mean operative time was 216 A +- 100 minutes and mean length of hospital stay was as 2.7 A +- 1.04 days. There were 10 complications in 28 cases, majority being Clavien Grade II including 7% (2/28) blood transfusion. Conclusion: There are technical challenges in learning laparoscopy for practicing urologists. Following some learning model in a systematic manner will help surmounting the technical challenges in learning laparoscopy. (author)

Full Text Available Background: More than 3 decades after the introduction of in vitro fertilization (IVF and despite the improved success rates of assisted reproductive technologies, the argument for performing laparoscopy as a part of the infertility workup still stands. Objective: To evaluate the role of laparoscopy±hysteroscopy in diagnosis and management of infertility in our setting in view of modern fertility practice. Materials and Methods: This case control study was carried out on 600 infertile women subjected to laparoscopy or combined laparoscopy and hysteroscopy at endoscopy unit in Minia University Hospital, Egypt during the period from January 2012 to December 2014. Results: The causes of infertility as identified by laparoscopy±hysteroscopy were polycystic ovary syndrome (25.1%, tubal factor (30%, uterine cause (4%, and endometriosis (2.7%. No cause was identified in 38.2% of cases. Based on operative findings, women were treated with different options. Expectant management was used in 92 cases (15.3%. Ovulation induction with anti-estrogens or gonadotropins was used in 372 cases (62%. Sixty cases (10% had intrauterine insemination and sixty four cases (10.7% underwent in vitro fertilization (IVF / intracytoplasmic sperm injection (ICSI treatment. Within 1 yr after laparoscopy, 180 cases achieved pregnancy (30%. The most favorable outcome was recorded in women with unexplained infertility (36.7% of cases got pregnant followed by women with polycystic ovary syndrome (27.8%. Participants with uterine and tubal infertility factor achieved pregnancy in 25% and 22.8% of cases, respectively. The worst outcome was recorded in women with endometriosis. Conclusion: Laparoscopy still has an important role in the diagnosis and treatment of infertility.

Laparoscopic examination is a useful investigation in the evaluation of infertile women. To perform this test, pneumoperitoneum is required to distend the abdomen, improve visibility and displace the intestines out of the pelvis. Several gases have been used to achieve this purpose including Nitrous Oxide (N2O), Carbondioxide (CO2), Helium, Xenon andAir. This was a prospective study in a private fertility centre in Nnewi, Nigeria aimed at reducing the morbidities inherent in the use Room Air pneumoperitoneum for diagnostic laparoscopy. This was sequel to an earlier study, which revealed that women who had Room Air pneumoperitoneum had a higher port wound infection rate, abdominal discomfort (feeling of retained gas in the abdomen) and shoulder pain with resultant delayed return to normal activity than women who had Co2 pneumoperitoneum. This study demonstrated that the use of soda lime to purify the Room Air and a low pressure suction pump to evacuate the air after the procedure significantly reduced the wound infection rate and virtually eliminated the abdominal discomfort and shoulder pain associated with Room Air pneumoperitoneum. This was followed by early return to normal activity. Therefore, use of Room Air for pneumoperitoneum is safe and affordable. It is recommended for low resource settings.

Full Text Available Ovarian ectopic pregnancies are a rare occurrence; however the incidence is on the rise. Preoperative diagnosis remains difficult due to nonspecific clinical symptoms and USS findings. Most patients undergo diagnostic laparoscopy with subsequent surgical management. We present the case of a 32-year-old female who presented with vaginal bleeding and an unsited pregnancy, with a BhCG of 24693. Formal USS described unruptured right tubal ectopic with ovarian pregnancy being diagnosed at laparoscopy. A wedge resection was conducted to preserve ovarian function. Postoperative recovery was uneventful and BhCG levels returned to zero (nonpregnant in an outpatient setting. Although laparoscopy remains the gold standard of diagnosis and treatment, in this case report we discuss benefits of early diagnosis for fertility conserving management, including nonsurgical options.

To evaluate the clinical value of staging laparoscopy in treatment decision-making for advanced gastric cancer (GC). Clinical data of 582 patients with advanced GC were retrospectively analyzed. All patients underwent staging laparoscopy. The strength of agreement between computed tomography (CT) stage, endoscopic ultrasound (EUS) stage, laparoscopic stage, and final stage were determined by weighted Kappa statistic (Kw). The number of patients with treatment decision-changes was counted. A χ(2) test was used to analyze the correlation between peritoneal metastasis or positive cytology and clinical characteristics. Among the 582 patients, the distributions of pathological T classifications were T2/3 (153, 26.3%), T4a (262, 45.0%), and T4b (167, 28.7%). Treatment plans for 211 (36.3%) patients were changed after staging laparoscopy was performed. Two (10.5%) of 19 patients in M1 regained the opportunity for potential radical resection by staging laparoscopy. Unnecessary laparotomy was avoided in 71 (12.2%) patients. The strength of agreement between preoperative T stage and final T stage was in almost perfect agreement (Kw = 0.838; 95% confidence interval (CI): 0.803-0.872; P advanced GC and decrease unnecessary exploratory laparotomy.

Purpose: To evaluate the use of laparoscopy, CT, colonic enema (CE), and laboratory tests (white blood cell count (WBC), sedimentation rate (SR), and C-reactive protein (CRP)) in diagnosing diverticulitis of the sigmoid colon. Material and Methods: The diagnostic methods were prospectively evaluated in 88 patients, 30 of whom were referred for laparoscopy. Results: Fity-two patients were found to have sigmoid diverticulitis: 20 patients by lanparoscopy, 21 by CT, and 11 by CE combined with one positive laboratory test. Laparoscopy proved to be superior to the other diagnostic methods in diagnosing diverticulitis of the sigmoid colon. CT had a high specificity (1.0; 95% CI: 0.92-1.0) but low sensitivity (0.69; 95% CI: 0.56-0.79) in detecting diverticulitis. CE had a higher sensitivity (0.82; 95% CI: 0.71-0.90) but a lower specificity (0.81; 95% CI: 0.67-0.91) than CT. Conclusion: CT was the best method for diagnosing abdominal pathology outside the colon. CT can be recommended as the first examination in seriously ill patients where abscesses and other causes of the symptoms than diverticulitis must first be rule out. Laparoscopy is probably the most accurate method in diagnosing diverticulitis. (orig.)

Although laparoscopy is becoming the standard of care for the treatment of colorectal disease, its application in case of postoperative peritonitis is still not widespread. The objective of this article is to evaluate the role of laparoscopy in the management of postoperative peritonitis after elective minimally invasive colorectal resection for malignant and benign diseases. Between April 2010 and May 2016, 536 patients received primary minimally invasive colorectal surgery at our Department. Among this series, we carried out a retrospective study of those patients who, having developed signs of peritonitis, were treated with a laparoscopic reintervention. Patient demographics, type of complication and of the main relaparoscopic treatment, and main outcomes of reoperation were recorded. A total of 20 patients (3.7%) underwent relaparoscopy for the management of postoperative peritonitis, of which exact causes were detected by laparoscopy in 75% as follows: anastomotic leakage (n = 8, 40%), colonic ischemia (n = 2, 10%), iatrogenic bowel tear (n = 4, 20%), and other (n = 1, 5%). The median time between operations was 3.5 days (range, 2-8). The laparoscopic reintervention was tailored case by case and ranged from lavage and drainage to redo anastomosis with ostomy fashioning. Conversion rate was 10% and overall morbidity was 50%. No cases required additional surgery and 30-day mortality was nil. Three patients (15%) were admitted to intensive care unit for 24-hour surveillance. Our experience suggests that in experienced hands and in hemodynamically stable patients, a prompt laparoscopic reoperation appears as an accurate diagnostic tool and an effective and safe option for the treatment of postoperative peritonitis after primary colorectal minimally invasive surgery.

Unexplained abdominal pain is a common but difficult presenting feature faced by the clinicians. Such patients can undergo a number of investigations with failure to reach any diagnosis. The objective of this study was to evaluate the use of laparoscopy in the diagnosis and management of patients with unexplained abdominal pain. Methods: This cross-sectional study was conducted at Pakistan Institute of Medical Sciences Islamabad from January 2009 to December 2013. This study included 91 patients of unexplained abdominal pain not diagnosed by routine clinical examination and investigations. These patients were subjected to diagnostic laparoscopy for evaluation of their conditions and to confirm the diagnosis. These patients presented 43% of patients undergoing investigations for abdominal pain. Patients diagnosed with gynaecological problems were excluded to see surgeon's perspective. The findings and the outcomes of the laparoscopy were recorded and data was analyzed. Results: Unexplained abdominal pain is common in females than in males. The most common laparoscopic findings were abdominal tuberculosis followed by appendicitis. Ninety percent patients achieved pain relief after laparoscopic intervention. Conclusion: Laparoscopy is both beneficial and safe in majority of patients with unexplained abdominal pain. General surgeons should acquire training and experience in laparoscopic surgery to provide maximum benefit to these difficult patients. (author)

Despite improved preoperative imaging techniques, patients with incurable or unresectable gastric cancer are still subjected to non-therapeutic laparotomy. Diagnostic laparoscopy (DL) has been advocated by some to be essential in decision-making in gastric cancer. We aimed to identify and synthesize findings on the value of DL for patients with gastric cancer, in this era of improved preoperative imaging. Electronic literature searches were conducted using Medline, EMBASE, and the Cochrane Central Register of Controlled Trials from January 1, 1998 to December 31, 2009. We calculated the change in management and avoidance of laparotomy based on the addition of DL and laparoscopic ultrasound (LUS). The accuracy, agreement (kappa), sensitivity, and specificity of DL in assessing tumor extent, nodal involvement, and the presence of metastases with respect to the gold standard (pathology) were also calculated. Twenty-one articles were included. DL showed moderate to substantial agreement with final pathology for T stage, but only fair agreement for N stage. For M staging, DL had an overall accuracy, sensitivity, and specificity ranging from 85-98.9%, 64.3-94%, and 80-100%, respectively. The use of DL altered treatment in 8.5-59.6% of cases, avoiding laparotomy in 8.5-43.8% of cases. LUS provided additional benefit in 5.8-7.2% of cases. Despite evolving preoperative imaging techniques, diagnostic laparoscopy continues to be of substantial value in staging patients with gastric cancer and in avoiding unnecessary laparotomy. The current data support DL for all patients with advanced gastric cancer.

Accurate preoperative staging helps avert morbidity, mortality, and cost associated with non-therapeutic laparotomy in gastric cancer (GC) patients. Diagnostic staging laparoscopy (DSL) can detect metastases with high sensitivity, but its cost-effectiveness has not been previously studied. We developed a decision analysis model to assess the cost-effectiveness of preoperative DSL in GC workup. Analysis was based on a hypothetical cohort of GC patients in the U.S. for whom initial imaging shows no metastases. The cost-effectiveness of DSL was measured as cost per quality-adjusted life-year (QALY) gained. Drivers of cost-effectiveness were assessed in sensitivity analysis. Preoperative DSL required an investment of $107 012 per QALY. In sensitivity analysis, DSL became cost-effective at a threshold of $100 000/QALY when the probability of occult metastases exceeded 31.5% or when test sensitivity for metastases exceeded 86.3%. The likelihood of cost-effectiveness increased from 46% to 93% when both parameters were set at maximum reported values. The cost-effectiveness of DSL for GC patients is highly dependent on patient and test characteristics, and is more likely when DSL is used selectively where procedure yield is high, such as for locally advanced disease or in detecting peritoneal and superficial versus deep liver lesions. © 2017 Wiley Periodicals, Inc.

Background: Chronic abdominal Pain in children is a very common cause of hospital admission. Many of them are discharged without a diagnosis even after battery of investigations. Laparoscopy plays a significant role in diagnosis and management of many causes of acute and chronic abdominal pain. The purpose of this study was to determine the efficacy of laparoscopy as an efficient diagnostic and management tool in children with chronic abdominal pain. Methods: A descriptive, prospective case series was collected in the department of Paediatric surgery Mayo Hospital Lahore, over the period of 5 years between Jan 2007- Dec 2013. The data of consecutive 50 patients, who were admitted in the department with the diagnosis of chronic abdominal pain, was recorded. All patients who had 2-3 admissions in hospital for last 2 months and failed to establish a definitive diagnosis after clinical examination and base line investigations underwent laparoscopy. The details of associated symptoms, finding of laparoscopy, laparoscopic procedures done, definitive diagnosis, histopathology, complications and relief of symptoms were collected and analysed and results were evaluated using SPSS17. Results: Out of 50 patients studies, 27/50 (54 percentage) were male, 23/50 (46 percentage) were female. Age ranged from 2-12 years, with the mean age of 7.24 year. Tuberculosis abdomen, adhesions, mesenteric lymphadenitis, appendicitis and cholecystitis were the final diagnosis. Five abdomens were found normal on laparoscopy. Complete pain relief was achieved in 30/50 (60 percentage), reduced intensity of pain was gained in 12/50 (24 percentage) cases while 16 percentage (8/50) still complained of pain. Conclusions: Laparoscopy is an efficient diagnostic and treatment tool in children with chronic unexplained abdominal pain. It avoids serial examinations; prolong admission, battery of investigations and unnecessary surgeries. (author)

Gynecologic applications of optical coherence tomography (OCT) are usually performed in combination with routine diagnostic procedures: laparoscopy and colposcopy. In combination with laparoscopy OCT is employed for inspection of fallopian tubes in cases of unrecognized infertility while in colposcopy it is used to identify cervix pathologies including cancer. In this paper we discuss methods for increasing diagnostic efficacy of OCT application in these procedures. For OCT-laparoscopy we demonstrate independent criteria for pathology recognition which allow to increase accuracy of diagnostics. For OCT-colposcopy we report on application of device for controlled compression allowing to sense the elasticity of the inspected cervix area and distinguish between neoplasia and inflammatory processes.

The aim of this study was to evaluate accuracy, tolerability and side effects of office hysteroscopic-guided chromoperturbations in infertile women without anaesthesia. Forty-nine infertile women underwent the procedure to evaluate tubal patency and the uterine cavity. Women with unilateral or bilateral tubal stenosis at hysteroscopy with chromoperturbation, and women with bilateral tubal patency who did not conceive during the period of six months, underwent laparoscopy with chromoperturbation. The results obtained from hysteroscopy and laparoscopy in the assessment of tubal patency were compared. Sensitivity, specificity, accuracy, positive-predictive value and negative-predictive value were used to describe diagnostic performance. Pain and tolerance were assessed during procedure using a visual analogue scale (VAS). Side effects or late complications and pregnancy rate were also recorded three and six months after the procedure. The specificity was 87.8% (95% CI: 73.80-95.90), sensitivity was 85.7% (95% CI 57.20-98.20), positive and negative predictive values were 70.6% (95% CI: 44.00-89) and 94.7% (95% CI: 82.30-99.40), respectively. Pregnancy rate (PR) within six months after performance of hysteroscopy with chromoperturbation was 27%. Office hysteroscopy-guided selective chromoperturbation in infertile patients is a valid technique to evaluate tubal patency and uterine cavity.

Over the past 2 decades, laparoscopy has been established as a superior technique in many general surgery procedures. Few studies, however, have examined the impact of the use of a laparoscopic approach in patients with symptomatic congestive heart failure (CHF). Because pneumoperitoneum has known effects on cardiopulmonary physiology, patients with CHF may be at increased risk. This study examines current trends in approaches to patients with CHF and effects on perioperative outcomes. The 2005-2011 National Surgical Quality Improvement Program Participant User File was used to identify patients who underwent the following general surgery procedures: Appendectomy, segmental colectomy, small bowel resection, ventral hernia repair, and splenectomy. Included for analysis were those with newly diagnosed CHF or chronic CHF with new signs or symptoms. Trends of use of laparoscopy were assessed across procedure types. The primary endpoint was 30-day mortality. The independent effect of laparoscopy in CHF was estimated with a multiple logistic regression model. A total of 265,198 patients were included for analysis, of whom 2,219 were identified as having new or recently worsened CHF. Of these patients, there were 1,300 (58.6%) colectomies, 486 (21.9%) small bowel resections, 216 (9.7%) ventral hernia repairs, 141 (6.4%) appendectomies, and 76 (3.4%) splenectomies. Laparoscopy was used less frequently in patients with CHF compared with their non-CHF counterparts, particularly for nonelective procedures. Baseline characteristics were similar for laparoscopy versus open procedures with the notable exception of urgent/emergent case status (36.4% vs 71.3%; P surgery procedures, particularly in urgent/emergent cases. Despite these patterns and apparent preferences, laparoscopy seems to offer a safe alternative in appropriately selected patients. Because morbidity and mortality were considerable regardless of approach, further understanding of appropriate management in this

Three-dimensional laparoscopy: Principles and practice

Full Text Available The largest challenge for laparoscopic surgeons is the eye–hand coordination within a three-dimensional (3D scene observed on a 2D display. The 2D view on flat screen laparoscopy is cerebrally intensive. The loss of binocular vision on a 2D display causes visual misperceptions, mainly loss of depth perception and adds to the surgeon's fatigue. This compromises the safety of laparoscopy. The 3D high-definition view with great depth perception and tactile feedback makes laparoscopic surgery more acceptable, safe and cost-effective. It improves surgical precision and hand–eye coordination, conventional and all straight stick instruments can be used, capital expenditure is less and recurring cost and annual maintenance cost are less. In this article, we have discussed the physics of 3D laparoscopy, principles of depth perception, and the different kinds of 3D systems available for laparoscopy. We have also discussed our experience of using 3D laparoscopy in over 2000 surgeries in the last 4 years.

3D laparoscopy allows the surgeon to regain the sense of depth and improve accuracy. The aim of the study was to assess the impact of 3D in bariatric surgery. A retrospective cohort study was conducted. All our patients who underwent bariatric surgery (sleeve gastrectomy (SG) or gastric bypass (GB)) between 2013 and 2016 were included. We compared 3D laparoscopy cohort and 2D laparoscopy cohort. Variables are as follows: age, sex, DM, hypertension, surgeon experience, and type of intervention. Comparisons of operative time, hospital stay, conversion, complications, reoperation, and exitus are completed. Three hundred twelve consecutive patients were included. 56.9% of patients underwent GB and 43.1% SG. Global complications were 3.2% (fistula 2.5%, hemoperitoneum 0.3%, others 0.4%). One hundred four procedures were performed in the 3D cohort and 208 in the 2D cohort. The 2D cohort and 3D cohort were similar regarding the following: percentage of GB vs SG, age, gender, learning curve, diabetes mellitus 2, hypertension, and sleep apnea. The operating time and hospital stay were significantly reduced in the 3D cohort (144.07 ± 58.07 vs 172.11 ± 76.11 min and 5.12 ± 9.6 vs 7.7 ± 13.2 days. It was the same when we stratified the sample by type of surgery or experience of the surgeon. Complications were reduced in the 3D cohort in the surgeries performed by novice surgeons (10.2 vs 1.8%, p = 0.034). The use of 3D laparoscopy in bariatric surgery in our center has helped reducing the operating time and hospital stay, and improving the safety of the surgery, either in GB or SG, being equally favorable in novice or more experienced surgeons.

Full Text Available The present research provides analysis of results of preoperative examination of 680 patients with ectopic pregnancy depending on the range of surgical treatment. It has been shown that in case of progressive ectopic pregnancy the diagnostic significance of concentrations of human chorionic gonadotropin, transvaginal examination and laparos-copy depends on the duration of pregnancy. When the term of ectopic pregnancy is 3-4 weeks monitoring of p chorionic gonadotropin in blood serum (99.5%, transvaginal examination (58% and laparoscopy (78.5% are more informative. When the term of ectopic pregnancy is more than 4 weeks there is a high diagnostic value of monitoring p-subunit of chorionic gonadotropin (99.5%, transvaginal examination (68% and laparoscopy (99,5%. The research has proved that pregnancy period of 3-4 weeks is optimal for laparoscopy and other operations

Standard treatment of advanced ovarian cancer is surgery and chemotherapy. The goal of surgery is to remove all macroscopic tumour, as the amount of residual tumour is the most important prognostic factor for survival. When removal off all tumour is considered not feasible, neoadjuvant chemotherapy (NACT) in combination with interval debulking surgery (IDS) is performed. Current methods of staging are not always accurate in predicting surgical outcome, since approximately 40% of patients will have more than 1 cm residual tumour after primary debulking surgery (PDS). In this study we aim to assess whether adding laparoscopy to the diagnostic work-up of patients suspected of advanced ovarian carcinoma may prevent unsuccessful primary debulking surgery for ovarian cancer. Multicentre randomized controlled trial, including all gynaecologic oncologic centres in the Netherlands and their affiliated hospitals. Patients are eligible when they are planned for PDS after conventional staging. Participants are randomized between direct PDS or additional diagnostic laparoscopy. Depending on the result of laparoscopy patients are treated by PDS within three weeks, followed by six courses of platinum based chemotherapy or with NACT and IDS 3-4 weeks after three courses of chemotherapy, followed by another three courses of chemotherapy. Primary outcome measure is the proportion of PDS's leaving more than one centimetre tumour residual in each arm. In total 200 patients will be randomized. Data will be analysed according to intention to treat. Patients who have disease considered to be resectable to less than one centimetre should undergo PDS to improve prognosis. However, there is a need for better diagnostic procedures because the current number of debulking surgeries leaving more than one centimetre residual tumour is still high. Laparoscopy before starting treatment for ovarian cancer can be an additional diagnostic tool to predict the outcome of PDS. Despite the absence

The Roles of Laparoscopy in Treating Ovarian Cancer

Full Text Available Great advances in technology offer meticulous options of minimally invasive surgery to empower the gynecologists to manage patients of early ovarian cancer. Laparoscopy affords improved visualization of the pelvic peritoneum, diaphragm and the deep pelvic structures, and offers many advantages in the avoidance of long abdominal incision, including shorter hospital stay and a more rapid recovery time. Most studies showed that laparoscopy did not compromise the survival and recurrence prognosis in comparison with open abdominal approach of staging surgery. Contrarily, laparoscopy precludes the advantage of open surgery, such as manual examination of the full extent of the bowel and palpation of lymph nodes. Besides, laparoscopy technically hampers the removal of large ovarian mass, and laparoscopic cancer surgery has a potential risk of trocar site metastasis. As the trend shows that laparoscopy has been playing an important role in treating early ovarian cancer, we could expect laparoscopy to become an attractive surgical option in the future for ovarian cancers.

Twenty-five patients who underwent single-port assisted extracorporeal cystectomy (group 1), 33 patients who underwent conventional laparoscopy (group 2), and 25 patients who underwent laparotomy (group 3). Surgical outcomes, complications, and spillage rates in group 1 were compared with those in groups 2 and 3. Patients characteristics and tumor histologic findings were similar in the 3 groups. The mean (SD) largest diameter of ovarian cysts was 11.4 (4.2) cm in group 1, 9.7 (2.3) cm in group 2, and 12.0 (3.4) cm in group 3. Operative time in groups 1 and 2 was similar at 69.3 (26.3) minutes vs 73.1 (36.3) minutes (p = .66); however, operative time in group 1 was shorter than in group 3, at 69.3 (26.3) minutes vs 87.5 (26.6) minutes (p =.02). Blood loss in group 1 was significantly lower than in groups 2 and 3, at 16.0 (19.4) mL vs 36.1 (20.7) mL (p < .001) and 16.0 (19.4) mL vs 42.2 (39.7) mL (p = .005). The spillage rate in group 1 was profoundly lower than in group 2, at 8.0% vs 69.7% (p < .001). Single-port assisted extracorporeal cystectomy offers an alternative to conventional laparoscopy and laparotomy for management of large ovarian cysts, with comparable surgical outcomes. Furthermore, cyst content spillage rate in single-port assisted extracorporeal cystectomy was remarkably lower than that in conventional laparoscopy. Copyright © 2015. Published by Elsevier Inc.

Single-port laparoscopy has gained popularity within minimally invasive gynecologic surgery for its feasibility, cosmetic outcomes, and safety. However, within gynecologic oncology, there are limited data regarding short-term adverse outcomes and long-term hernia risk in patients undergoing single-port laparoscopic surgery. The objective of the study was to describe short-term outcomes and hernia rates in patients after single-port laparoscopy in a gynecologic oncology practice. A retrospective, single-institution study was performed for patients who underwent single-port laparoscopy from 2009 to 2015. A univariate analysis was performed with χ 2 tests and Student t tests; Kaplan-Meier and Cox proportional hazards determined time to hernia development. A total of 898 patients underwent 908 surgeries with a median follow-up of 37.2 months. The mean age and body mass index were 55.7 years and 29.6 kg/m 2 , respectively. The majority were white (87.9%) and American Society of Anesthesiologists class II/III (95.5%). The majority of patients underwent surgery for adnexal masses (36.9%) and endometrial hyperplasia/cancer (37.3%). Most women underwent hysterectomy (62.7%) and removal of 1 or both fallopian tubes and/or ovaries (86%). Rate of adverse outcomes within 30 days, including reoperation (0.1%), intraoperative injury (1.4%), intensive care unit admission (0.4%), venous thromboembolism (0.3%), and blood transfusion, were low (0.8%). The rate of urinary tract infection was 2.8%; higher body mass index (P = .02), longer operative time (P = .02), smoking (P = .01), hysterectomy (P = .01), and cystoscopy (P = .02) increased the risk. The rate of incisional cellulitis was 3.5%. Increased estimated blood loss (P = .03) and endometrial cancer (P = .02) were independent predictors of incisional cellulitis. The rate for surgical readmissions was 3.4%; higher estimated blood loss (P = .03), longer operative time (P = .02), chemotherapy alone (P = .03), and

Full Text Available Context: Women with primary infertility and no obvious pelvic pathology on clinical evaluation and imaging are either treated empirically or further investigated by laparoscopy. Aims: The role of diagnostic laparoscopy in women who fail to conceive after empirical treatment with ovulation induction and intrauterine insemination was evaluated. Settings and Design: Retrospective study at a private infertility center. Materials and Methods: A study of patients who underwent diagnostic laparoscopy between 1 st January 2001 and 31 st December 2008 was performed. Those patients who had no detectable pathology based on history, physical examination, and ultrasound and had treatment for three or more cycles in the form of ovulation induction and IUI were included in the study. Moderate and severe male factor infertility and history of any previous surgery were exclusion criteria. Statistical Analysis Used: Data were statistically analyzed using Statistics Package for Social Sciences (ver. 16.0; SPSS Inc., Chicago. Results: Of the 127 women who underwent diagnostic laparoscopy and hysteroscopy, 87.4% ( n= 111 of patients had positive findings. Significant pelvic pathology (moderate endometriosis, pelvic inflammatory disease, and tubal pathology was seen in 26.8% of cases. Conclusion: One in four women had significant pelvic pathology where treatment could possibly improve future fertility. Diagnostic laparoscopy has a role in infertile women with no obvious abnormality before they proceed to more aggressive treatments.

Diagnostic Laparoscopy as Decision Tool for Re-recurrent Inguinal Hernia Treatment Following Open Anterior and Laparo-Endoscopic Posterior Repair

Directory of Open Access Journals (Sweden)

Ferdinand Köckerling

2017-05-01

Full Text Available IntroductionThe guidelines of the international hernia societies recommend posterior repair in laparo-endoscopic technique for recurrent inguinal hernia after open anterior mesh repair and, conversely, open anterior repair for recurrence after laparo-endoscopic primary repair. Even when these guidelines are followed, already 1 year after repair a re-recurrence rate of 1–2% must be expected, with that rate rising further in the subsequent years. Accordingly, increasingly more patients with re-recurrence after anterior and posterior mesh implantation must be treated, which constitutes a problem that to date has been investigated in only very few studies. Hence, there are no well-founded recommendations. This paper now presents a number of case reports aimed at identifying the role of explorative laparoscopy as decision tool for re-recurrent inguinal hernia treatment.Patients and methodsBased on three case reports the role of explorative laparoscopy as decision tool for re-recurrent inguinal hernia treatment is presented below.ResultsIn all the three cases described explorative laparoscopy played a key role as decision tool when deciding how best to treat re-recurrence after anterior and posterior inguinal hernia repair. In one case severe adhesions after robotic prostatectomy and in another case correct placement of the mesh in the posterior plane, adhesions from the cecum to the groin region and no definitive finding of a re-recurrence resulted in an open repair. In the third case, an insufficient laparoscopic posterior mesh placement made the re-recurrent TAPP procedure relatively easy.ConclusionExplorative laparoscopy is an important decision tool for re-recurrent inguinal hernia treatment to minimize the risks of the procedure for the patients.

We present a novel minimally invasive technique, laparoscopy-assisted micropercutaneous choledocholithotripsy, for choledocholithiasis that cannot be treated with other endoscopic techniques. This technique includes standard laparoscopic exploration of the common bile duct, combined with an all-seeing needle and holmium laser lithotripsy. As is known, an all-seeing needle is used in micropercutaneous nephrolithotomy for middle-sized renal stones. In this technique, an all-seeing needle was inserted into the dilatated common bile duct under laparoscopic vision and then a lithotripsy procedure was performed with a holmium laser behind the biliary stent. A cholecystectomized female patient with a 21-mm stone in the common bile duct who previously underwent an unsuccessful endoscopic retrograde cholangiopancreatography procedure was operated on in our service with laparoscopy-assisted micropercutaneous choledocholithotomy without a T-tube. This novel procedure was completed uneventfully and the patient was discharged without any complications. In the future, this procedure will hopefully be a treatment modality in choledocholithiasis that cannot be treated by other minimally invasive techniques.

Laparoscopy-assisted total gastrectomy (LATG) is commonly performed for early gastric cancer (EGC) in the upper stomach; however, the incidence of anastomotic complications remains high, and postoperative nutritional status is not satisfactory. This study aimed to evaluate the feasibility and nutritional impact of a novel surgical procedure, laparoscopy-assisted subtotal gastrectomy (LAsTG). This was a retrospective study of 167 patients with EGC in the upper stomach. Of these, 57 patients underwent LAsTG, while 110 patients underwent LATG. Postoperative change in body weight, and serum concentration of albumin (Alb) and total protein (TP) were compared between the LAsTG and LATG groups. Analysis of covariance (ANCOVA) was used to assess the influence of potential confounding factors. Frequency of anastomotic complications was significantly higher in the LATG group (16.3 %) than in the LAsTG group (5.3 %, P = 0.040). Postoperative recovery of body weight at 12 months after surgery was significantly better in the LAsTG group (89.8 ± 1.4 %) than in the LATG group (82.1 ± 1.0 %, P nutritional status.

To study the accuracy of four-dimensional (4D) ultrasound and power Doppler flow mapping in detecting tubal patency in women with sub-/infertility, and compare it with laparoscopy and chromopertubation. A prospective study. The study was performed in the outpatient clinic and infertility unit of a university hospital. The sonographic team and laparoscopic team were blinded to the results of each other. Women aged younger than 43 years seeking medical advice due to primary or secondary infertility and who planned to have a diagnostic laparoscopy performed, were recruited to the study after signing an informed consent. All of the recruited patients had power Doppler flow mapping and 4D hysterosalpingo-sonography by injecting sterile saline into the fallopian tubes 1 day before surgery. Registering Doppler signals, while using power Doppler, both at the tubal ostia and fimbrial end and the ability to demonstrate the course of the tube especially the isthmus and fimbrial end, while using 4D mode, was considered a patent tube. Out of 50 recruited patients, 33 women had bilateral patent tubes and five had unilateral patent tubes as shown by chromopertubation during diagnostic laparoscopy. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy for two-dimensional power Doppler hysterosalpingography were 94.4%, 100%, 100%, 89.2%, and 96.2%, respectively and for 4D ultrasound were 70.4%, 100%, 100%, 70.4%, and 82.6%, respectively. Four-dimensional saline hysterosalpingography has acceptable accuracy in detecting tubal patency, but is surpassed by power Doppler saline hysterosalpingography. Power Doppler saline hysterosalpingography could be incorporated into the routine sub-/infertility workup. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Hydronephrosis is a common disease in children and may be caused by ureteral fibroepithelial polyps (UFP). Ureteral fibroepithelial polyps are rare in children and are difficult to precisely diagnose before surgery. Surgical treatment for symptomatic UFP is recommended. At the present institution, retroperitoneal laparoscopy has been used to treat five boys with UFP since 2006. To highlight the significance of UFP as an etiological factor of hydronephrosis in children and evaluate the applicative value of retroperitoneal laparoscopy in the treatment of children with UFP. Between 2006 and 2013 five boys underwent retroperitoneal laparoscopy at the present institution. They were identified with UFP by review of the clinical database. Detailed data were collected, including: radiographic studies, gross anatomical pathology, and pathology and radiology reports. All boys had been followed up at least every 6 months. All of the boys were aged between 7 and 16 years (mean 9.8 years). The main symptoms were flank pain (all five) and hematuria (three). Radiographic examination showed that all of the boys presented with incomplete ureteral obstruction and hydronephrosis. The ureteral fibroepithelial polyps were located near the left UPJ or the left proximal ureter. All of the boys had the UFP removed: three underwent retroperitoneal laparoscopic dismembered Anderson-Hynes pyeloplasty and polypectomy, and two had retroperitoneal laparoscopic ureteral anastomosis. These polyps were all on the left side and between 15 and 35 mm in length (mean 22 mm) (Figure). All of the boys recovered well and were discharged from hospital. The postoperative histological report confirmed that the specimens were UFP. Hydronephrosis was periodically assessed by ultrasonography (using the same method as pre-surgical ultrasonography) after surgery. Mean follow-up was 33 months (range 6-58 months) and no complications were found afterwards. Ureteral fibroepithelial polyps are rare but rather

A polycystic ovaries disease occurs in the case of women with anovulatory cycles as the result of neurohormonal disorders. Patients with this disease suffer from infertility and many symptoms, such as: irregular menstrual bleeding, hirsutism, obesity. The paper presents a method of the carbon dioxide laser laparoscopy in the polycystic ovary disease treatment. The study included 96 women operated on (carbon dioxide laser laparoscopy) in the II Clinic Of Obstetric and Gynecology in Warsaw. Each woman measured her body temperature in order to evaluate her menstrual cycle and had vaginal USG examination or a cytohormonal one before laparoscopy and within 6 months after the surgery. Performing the laparoscopy the operator punctured each ovary in at least 15 points using the carbon dioxide laser. The patients were followed-up for 6 months. The Chi test was used to make the statistic analysis. Comparing the percent of ovulatory cycles and regular ones before and after surgery we noticed that the differences were statistically relevant. Eighty-five patients (88%) had regular cycles and in 88 cases (92%) there was a diphasic curve of the body temperature after the laparoscopy. Fourteen percent of infertile women with polycystic ovary disease conceived.

Objective was to compare tuboperitoneal factors of infertile women hysterosalpingography (HSG) and laparoscopy. In this cohort study, 82 infertile cases were evaluated retrospectively by laparoscopy, 3 months subsequent to HSG in the Department of Gynecology and Obstetrics, Medical School of Dicle University, Diyarbakir, Turkey between March 2004 and April 2006. The findings of HSG and laparoscopy were compared. Out of 82 infertile women, pathological findings were observed in 45.1% by HSG and 54.9% had no pathological findings. On laparoscopic evaluation, however, pathological findings were observed in 65.85% and 34.15% had no pathological findings. The pathological findings were detected by laparoscopy in 20 of the 45(44.4%) patients who had had no pathological findings by HSG and no pathological findings were detected by laparoscopy in 3 of the 37 (8.1%) patients who had pathological findings by HSG. Laparoscopy revealed no pathological findings in 6 of 35 patients who had tubal pathology by HSG. The sensitivity of HSG was 63%, specificity was 89.3% and positive predictive value was 92% with a 55% predictive value and the accuracy ratio was 72%. Laparoscopy is a superior method for the result of tubal and pelvic pathologies in the evaluation of infertility. However, HSG is a more economical and elementary method suitable for evaluation of endometrial and tubal pathologies and laparoscopy is an appropriate method for examining the external part of tubae, fimbriae, the relation of tuba and ovary, endometriosis, adhesions, tuberculosis and other pathologies. Therefore, these 2 methods are not alternative but complementary. (author)

To evaluate systemic markers of immune and stress responses after bilateral adnexectomy performed using 2 different laparoscopic techniques in pigs. Prospective comparative study (Canadian Task Force classification II-2). University teaching hospital, research hospital, and tertiary care center. Twenty female Yorkshire pigs undergoing laparoscopic surgery. Animals underwent bilateral salpingo-oophorectomy (ovary and fallopian tube extraction), performed via conventional laparoscopy (n = 10) or the single-port access approach (n = 10). Injury provokes an acute-phase response, primarily produced by cytokines. The inflammatory response has been well described for major surgery and for conventional laparoscopy; however, little information is currently available for single-port laparoscopy, and none in the gynecologic field. This is the first study to compare serum cytokine interleukin 6 (IL-6) and tumor necrosis factor alpha (TNF-α) concentrations at baseline and in the early postoperative period (2, 4, and 20 hours) after bilateral salpingo-oophorectomy performed via conventional laparoscopy (n = 10) or single-port access (n = 10) in a porcine model. The stress response was measured using glucose and cortisol concentrations and the animals' response to surgery via a 6-category observation-based behavior test. Both IL-6 and TNF-α concentrations peaked at 4 hours after surgery, and were significantly lower in the single-port access group (p = .02) than in the conventional laparoscopy group (p = .02). In addition, in the single-port access group, concentrations of stress markers were slightly lower at all intervals recorded and were statistically significant at 2 hours after the operation for glucose concentration (mean [SD], 164.50 [26.73] mg/dL for conventional laparoscopy vs 86.50 [17.93] mg/dL for single-port access; p = .02). Evidence of improved inflammatory and stress responses was recorded in the minimally invasive single-port group. More clinical

Single-port laparoscopy is prospected as the future of minimal invasive surgery. It is hypothesised to cause less post operative pain, with a shorter hospitalisation period and improved cosmetic results. Population- and patient-based opinion is important for the adaptation of new techniques. This study aimed to assess the opinion and perception of a healthy population and a patient population on single-port laparoscopy compared with conventional laparoscopy. An anonymous 33-item questionnaire, describing conventional and single-port laparoscopy, was given to 101 patients and 104 healthy volunteers. The survey participants (median age 44 years; range 17-82 years) were asked questions about their personal situation and their expectations and perceptions of the two different surgical techniques; conventional multi-port laparoscopy and single-port laparoscopy. A total of 72% of the participants had never heard of single-port laparoscopy before. The most important concern in both groups was the risk of surgical complications. When complication risks remain similar, 80% prefers single-port laparoscopy to conventional laparoscopy. When the risk of complications increases from 1% to 10%, 43% of all participants prefer single-port laparoscopy. A total of 70% of the participants are prepared to receive treatment in another hospital if single-port surgery is not performed in their hometown hospital. The preference for single-port approach was higher in the female population. Although cure and safety remain the main concerns, the population and patients group have a favourable perception of single-port surgery. The impact of public opinion and patient perception towards innovative techniques is undeniable. If the safety of the two different procedures is similar, this study shows a positive attitude of both participant groups in favour of single-port laparoscopy. However, solid scientific proof for the safety and feasibility of this new surgical technique needs to be obtained

While laparoscopy-assisted endoscopic retrograde cholangiopancreatography can be performed for the diagnosis and management of pancreaticobiliary diseases in patients with Roux-en-Y (RY) anatomy; the technical feasibility of performing laparoscopy-assisted endoscopic ultrasound (EUS) is unknown. In this report, we describe the technique for performing laparoscopy-assisted EUS in two patients with RY gastric bypass anatomy who presented with obstructive jaundice, abnormal liver function tests, and dilated biliary tree. While the examination was normal in one patient, EUS-guided fine needle aspiration of pancreatic head mass revealed adenocarcinoma in the other. Laparoscopic assisted EUS examination including FNA is feasible in Roux-en-Y surgical anatomy.

BACKGROUND: Appendicitis is a frequent reason for hospital admissions. Elevated C-reactive protein, white blood cell count, and serum bilirubin have been suggested as individual markers for appendicitis and appendiceal perforation. The aim of this study was to analyze if a combination of serologic...... markers could increase the prognostic accuracy of diagnosing non-perforated and perforated appendicitis. MATERIAL AND METHODS: Demographic data, histological findings, blood tests, and clinical symptoms were collected on all patients who underwent a diagnostic laparoscopy, a laparoscopic appendectomy......, or conventional (open) appendectomy between May 2009 and May 2012 from a surgical department. The patients were grouped into those with either perforated appendicitis, non-perforated appendicitis, or differential diagnosis.

Laparoscopy introduction has dramatically changed urology. Novel techniques, such as laparoendoscopic single-site surgery (LESS) and natural orifice translumenal endoscopic surgery (NOTES), might also have substantial influence. This 2012 survey evaluated present laparoscopy use, its appraisal among urologic surgeons, laparoscopy training, and use of new techniques. Results were compared to the previous surveys, demonstrating the 10-year development of laparoscopy. A detailed questionnaire regarding demographic data, laparoscopy use, attitudes concerning laparoscopy, and novel techniques was send to 424 departments in Germany, Austria, and Switzerland. Procedures performed in 25 indications were quantitatively evaluated. The response rate was 63 % (269). Eighty-six percent of the respondents reported performing laparoscopy, compared to 54 % in 2002. Only 16 % expected economic advantages with laparoscopy, whereas 67 % expected shorter hospitalization. Seventy percent of responders anticipated comparable functional and oncological results between laparoscopic procedures and open surgery. Slow learning curves (81 %) and insufficient training facilities (32 %) were reported to impair laparoscopic surgery. On average, laparoscopic and non-laparoscopic surgical teams consisted of 2.5 and 3.5 members, respectively. LESS procedures were performed at 15 % of institutions. Twenty-two percent of respondents considered NOTES techniques valuable for future urology. Few indications (laparoscopic prostatectomies or nephrectomies) were performed frequently in specialized centers, and the rapidly increasing procedure numbers observed between 2002 and 2007 had dropped to a mild accretion. The results demonstrate broad acceptance of laparoscopy in German urologic surgery, depict the need for structured training facilities, and indicate limited impact of novel techniques (LESS and NOTES). The survey demonstrates the 10-year development of urologic laparoscopy and the broad acceptance

To date there have been no comprehensive, comparative assessments of the environmental impact of surgical modalities. Our study seeks to quantify and compare the total greenhouse gas emissions, or 'carbon footprint', attributable to three surgical modalities. A review of 150 staging procedures, employing laparotomy (LAP), conventional laparoscopy (LSC) or robotically-assisted laparoscopy (RA-LSC), was performed. The solid waste generated (kg) and energy consumed (kWh) during each case were quantified and converted into their equivalent mass of carbon dioxide (kg CO(2) e) release into the environment. The carbon footprint is the sum of the waste production and energy consumption during each surgery (kg CO(2) e). The total carbon footprint of a RA-LSC procedure is 40.3 kg CO(2) e/patient (p < 0.01). This represents a 38% increase over that of LSC (29.2 kg CO(2) e/patient; p < 0.01) and a 77% increase over LAP (22.7 kg CO(2) e/patient; p < 0.01). Our results provide clinicians, administrators and policy-makers with knowledge of the environmental impact of their decisions to facilitate adoption of sustainable practices.

The malignant form of atrophic papulosis (Köhlmeier-Degos disease) is a rare thrombo-occlusive vasculopathy that can affect multiple organ systems. Patients typically present with distinctive skin lesions reflective of vascular drop out. The small bowel is the most common internal organ involved, resulting in considerable morbidity and mortality attributable to ischemic microperforations. Determination of the presence of gastrointestinal lesions is critical in distinguishing systemic from the benign, cutaneous only disease and in identifying candidates for treatment. We describe an 18 year old male who first presented with cutaneous atrophic papulosis but became critically ill from small bowel microperforations. He had an almost immediate and dramatic response to treatment. Prior to his presentation with acute abdomen he had upper and lower endoscopy showing areas of nonspecific patchy erythema. At laparotomy, innumerable characteristic lesions with central pearly hue and erythematous border were seen. PubMed was used for a literature search using the keywords malignant atrophic papulosis, Degos disease, endoscopy, laparoscopy and laparotomy. This search yielded 200 articles which were further analyzed for diagnostic procedures and findings. Among the 200 articles we identified only 11 cases in which endoscopy was performed. Results of endoscopy and laparotomy in our patient with malignant atrophic papulosis were compared to those in the literature. Endoscopy of the gastrointestinal tract has shown gastritis and non-specific inflammation whereas laparoscopy shows white plaques with red borders on the serosal surface of the small bowel and the peritoneum. From personal communications with other physicians worldwide, we identified three additional unpublished cases in which endoscopy revealed only minimal changes while laparoscopy showed dramatic lesions. From our experience the endoscopic findings are often subtle and nonspecific, whereas laparascopy or laparotomy

Compared to aviation, where virtual reality (VR) training has been standardized and simulators have proven their benefits, the objectives, needs, and means of VR training in minimally invasive surgery (MIS) still have to be established. The aim of the study presented is to introduce Rasmussen's model of human behavior as a practical framework for the definition of the training objectives, needs, and means in MIS. Rasmussen distinguishes three levels of human behavior: skill-, rule-, and knowledge-based behaviour. The training needs of a laparoscopic novice can be determined by identifying the specific skill-, rule-, and knowledge-based behavior that is required for performing safe laparoscopy. Future objectives of VR laparoscopy trainers should address all three levels of behavior. Although most commercially available simulators for laparoscopy aim at training skill-based behavior, especially the training of knowledge-based behavior during complications in surgery will improve safety levels. However, the cost and complexity of a training means increases when the training objectives proceed from the training of skill-based behavior to the training of complex knowledge-based behavior. In aviation, human behavior models have been used successfully to integrate the training of skill-, rule-, and knowledge-based behavior in a full flight simulator. Understanding surgeon behavior is one of the first steps towards a future full-scale laparoscopy simulator.

Full Text Available BACKGROUND Laparoscopy has been a new entry in the field of surgery with an active history of around just two decades. Today, it is in a position to challenge the conventional surgery which is in use since ages. It is making rapid inroads into various disciplines of surgery. Rapid improvements in optics, along with improvements in energy devices and mechanical stapling devices gave a fillip to acceptance of laparoscopy by the majority of surgeons. Also accumulating data and evidence has started influencing the sceptical, mobilising them to jump into the bandwagon. Barriers to adoption of new techniques, resistance to learning are common to human nature and it is necessary to have a systematic overview of the issues that might crop, so as to be prepared to overcome the problems of accepting laparoscopy into established centres of surgery. AIMS This publication is a reflection of our experience, our trials and tribulations in taking forward the laparoscopy program at our institution. This publication will give an overview of the steps involved in initiation of laparoscopy and aspires to be a source of answers, for day-to-day issues that crop during the process of learning laparoscopy. METHODS AND MATERIALS Just the way, executing laparoscopic surgery is a team effort, incorporating laparoscopy program in an institution is also a team effort where the members of team extend beyond the operating room. Involvement and co-operation of individuals across departments is a must along with benevolent seniors and a proactive administration. So we collated data by interviewing all the stakeholders of laparoscopy program, analysed observations of the faculty from the operating room and reviewed literature on the world wide web. Opinions of the administrators about their perceptions and the issues faced by the junior staff of the department were taken into consideration. Patients were interviewed before and after laparoscopic surgery. CONCLUSIONS Success at

The purpose of this study was to compare the costs of traditional laparoscopy and robotic-assisted laparoscopy in the treatment of endometrial cancer. A total of 101 patients with endometrial cancer were randomized to the study and operated on starting from 2010 until 2013, at the Department of Obstetrics and Gynecology of Tampere University Hospital, Tampere, Finland. Costs were calculated based on internal accounting, hospital database, and purchase prices and were compared using intention-to-treat analysis. Main outcome measures were item costs and total costs related to the operation, including a 6-month postoperative follow-up. The total costs including late complications were 2160 &OV0556; higher in the robotic group (median for traditional 5823 &OV0556;, vs robot median 7983 &OV0556;, P costs for instruments and equipment as well as to more expensive operating room and postanesthesia care unit time. Traditional laparoscopy involved higher costs for operation personnel, general costs, medication used in the operation, and surgeon, although these costs were not substantial. There was no significant difference in in-patient stay, laboratory, radiology, blood products, or costs related to complications. According to this study, robotic-assisted laparoscopy is 37% more expensive than traditional laparoscopy in the treatment of endometrial cancer. The cost difference is mainly explained by amortization of the robot and its instrumentation.

Aim: To evaluate the accuracy of water enema computed tomography (CT) for predicting the location of endometriosis in patients with contraindications to magnetic resonance imaging (MRI), focusing on rectosigmoid lesions and having laparoscopic and histological data as the reference standard. Materials and methods: Thirty-three women (mean age 33.4 ± 3.1 years) suspected of having deep pelvic endometriosis underwent 64-row CT and video laparoscopy within 4 weeks. Two radiologists blinded to the clinical data evaluated the CT images obtained after colonic retrograde distension using water as the contrast medium, and a comparison with laparoscopic and histological findings was performed. CT sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and diagnostic accuracy were calculated. The radiation dose to patients was estimated. Cohen's weighted kappa (κ) test was used to evaluate the interobserver agreement. Results: In 23 out of 33 patients (69%) intestinal implants were found at surgery and pathological examinations. CT confirmed the diagnosis of rectosigmoid endometriosis in 20 out of 23 implants. Three nodules located on the proximal sigmoid colon (two serosal lesions and one infiltrating the muscularis layer) with a diameter of less than 1 cm were not diagnosed. CT sensitivity, specificity, PPV, NPV, and accuracy values were 87, 100, 100, 77, and 91%, respectively. The mean effective dose estimate was 6.30 ± 1.7 mSv. Almost perfect agreement between the two readers was found (k = 0.84). Conclusion: Water enema CT can play a role in the diagnosis of bowel endometriosis and represents another accurate potential tool for video laparoscopic approaches, especially in patients for whom MRI is contraindicated

Acute small bowel obstruction (SBO) is an urgent medical condition. Its diagnosis is based mainly on a clinical examination followed by confirmatory simple routine radiological examinations such as plain X-ray of the abdominal cavity or computed tomography (CT). However, a real surgical challenge is not a decision whether to perform a surgery, but a decision when and how to perform it. To determine the place of laparoscopy in contemporary management of acute SBO based on the current literature. A review of the literature based on the Medline database and including mainly the period of 2013-2017 was performed. With regard to SBO, laparoscopy is a technique showing its advantages resulting from a minimally invasive approach. However, SBO is still a condition where the use of laparoscopy is limited mainly to selected cases such as SBO caused by single adhesions or foreign bodies. A basic limitation of using this technique is advanced and complicated SBO and lack of sufficient technical skills of the surgeon.

A real time ultrasonography was set up in a senegalese hospital, resulting in a decrease of laparoscopy indications. Laparoscopy is given up for the diagnosis of liver abcess, jaundice and "abdominal masses". It must no more be included in the first step check up for hepatocellular carcinoma, because ultrasonography and cytology after puncture are enough to confirm the diagnosis. Laparoscopy remains essential for peritoneal diseases. Hepatic needle biopsy under laparoscopy control remains necessary to ensure with certainty the diagnosis of cirrhosis and especially chronic hepatitis, provided that no countraindications are found.

To perform a comprehensive literature review of the incidence, location, etiology, timing, management, and long-term sequelae of urinary tract injury in gynecologic laparoscopy for benign indication. A systematic review of PubMed, EMBASE, Cochrane Library, and ClinicalTrials.gov was conducted. Four hundred thirty-three studies were screened for inclusion with 136 full-text articles reviewed. Ninety studies published between 1975 and 2015 met inclusion criteria, representing 140,444 surgeries. Articles reporting the incidence of urinary tract injury in gynecologic laparoscopy for benign indication were included. Exclusion criteria comprised malignancy, surgery by urogynecologists, research not in English, and insufficient data. A total of 458 lower urinary tract injuries were reported with an incidence of 0.33% (95% CI 0.30-0.36). Bladder injury (0.24%, 95% CI 0.22-0.27) was overall three times more frequent than ureteral injury (0.08%, 95% CI 0.07-0.10). Laparoscopic hysterectomy not otherwise specified (1.8%, 95% CI 1.2-2.6) and laparoscopically assisted vaginal hysterectomy (1.0%, 95% CI 0.9-1.2) had the highest rates of injury. Most ureteral injuries resulted from electrosurgery (33.3%, 95% CI 24.3-45.8), whereas most bladder injuries resulted from lysis of adhesions (23.3%, 95% CI 18.7-29.0). Ureteral injuries were most often recognized postoperatively (60%, 95% CI 47-76) and were repaired by open ureteral anastomosis (47.4%, 95% CI 36.3-61.9). In contrast, bladder injuries were most often recognized intraoperatively (85%, 95% CI 75-95) and were repaired by laparoscopic suturing (34.9%, 95% CI 29.2-41.7). The incidence of lower urinary tract injury in gynecologic laparoscopy for benign indication remains low at 0.33%. Bladder injury was three times more common than ureteral injury, although ureteral injuries were more often unrecognized intraoperatively and underwent open surgical repair. These risk estimates can assist gynecologic surgeons in effectively

Despite proven safety and efficacy, rates of minimally invasive approaches for colon cancer remain low in the USA. Given the known benefits, investigating the root causes of underutilization and methods to increase laparoscopy is warranted. Our goal was to develop a predictive model of factors impacting use of laparoscopic surgery for colon cancer. The Premier Hospital Database was reviewed for elective colorectal resections for colon cancer (2009-2014). Patients were identified by ICD-9-CM diagnosis code and then stratified into open or laparoscopic approaches by ICD-9-CM procedure codes. An adjusted multivariate logistic regression model identified variables predictive of use of laparoscopy for colon cancer. A total of 24,245 patients were included-12,523 (52 %) laparoscopic and 11,722 (48 %) open. General surgeons performed the majority of all procedures (77.99 % open, 71.60 % laparoscopic). Overall use of laparoscopy increased from 48.94 to 52.03 % over the study period (p colon cancer laparoscopically.

However, additional patients may be eligible for laparoscopy based on patient-level characteristics. These results have implications for regionalization and increasing teaching of MIS. Recognizing and addressing these variables with training and recruiting could increase use of minimally invasive approaches, with the associated clinical and financial benefits.

Full Text Available Background. The aim of this retrospective study was to find the incidence and type of adnexal masses in pregnancy, reliability of preoperative ultrasound examination and the effect of the surgical approach used, duration of pregnancy at the time of surgery, and the effect of emergency or planned surgery on the outcome of pregnancy. The obtained results and the data from literature were to provide the basis of the guidelines for the management of pregnant women with adnexal masses.Methods. In the study we enrolled 42 women, who underwent a surgery in pregnancy for adnexal masses. All surgeries were performed at the Department of Obstetrics and Gynecology in the period 1 January 1993–31 August 2000. The course of pregnancy was followed by 28 February 2001. The data were obtained from the records kept at the Department and from the questionnaire sent to the women. Statistical analysis was done using Chi-square test. Statistical significance was set at P ≤ 0.05.Results. We found the incidence of adnexal masses in pregnancy, requiring surgical treatment, to be 1/1034 deliveries. There were 6 (14.3% borderline malignant and malignant ovarian tumours, the incidence being 1/7239 deliveries. Preoperative ultrasound examination was not reliable enough to differentiate neither between benign and malignant adnexal masses, nor between adnexal masses and leiomyomas. Forty-two surgeries were made, 21 by laparoscopy and 21 by laparotomy. The size of removed tumours ranged between 4 and 30 cm (mean 9.4 cm, the most frequent type was mature cystic teratoma (n = 12. There were no differences in the outcome of pregnancy between the laparoscopy and laparotomy approach, between emergency and planned surgery, and between laparotomy performed by the 23rd and after the 23rd gestational week. Hemorrhagic shock due to heterotopic pregnancy lead to 1 spontaneous abortion. There were 2 preterm deliveries in the 37th week, 2 babies had intrauterine growth retardation

Sheikh, Abu Baker; Akhtar, Aisha; Nasrullah, Adeel; Haq, Shujaul; Ghazanfar, Haider

2017-06-17

A bezoar is a collection of indigestible material found in the alimentary canal, which can cause mechanical obstruction of the gastrointestinal tract. Phytobezoar is a variant composed of mostly plant material and indigestible fiber. Phytobezoar is a rare cause of small bowel obstruction (SBO) and happens more commonly in patients with risk factors predisposing to impaired gastrointestinal motility. We present a rare case of SBO secondary to phytobezoar in a 60-year-old female patient with type 2 diabetes. There was no prior history of any abdominal surgery. The abdominal computed tomography (CT) scan was inconclusive. Laparoscopy was found to be an effective diagnostic and therapeutic procedure in this patient.

Full Text Available Abstract Background Gynecological laparoscopic surgery procedures are often complicated by postoperative pain resulting in an unpleasant experience for the patient, delayed discharge, and increased cost. Glucocorticosteroids have been suggested to reduce the severity and incidence of postoperative pain. Methods This study examines the efficacy of a sustained release betamethasone preparation to reduce postoperative pain and the requirement for pain relief drugs after either diagnostic laparoscopy or tubal ligation. Patients were recruited, as presenting, after obtaining informed consent. Prior to surgery, patients were randomly selected by a computer generated table to receive either pharmacy-coded betamethasone (12 mg IM Celestone™ or an optically identical placebo injection of Intralipid™ and isotonic saline mixture. The effect of non-controlled prophylactic intraoperative treatment with either fentanyl or ketorolac per surgeon's orders was also noted in this study. Blood samples taken at recovery and at discharge times were extracted and analyzed for circulating betamethasone. Visual analog scale data on pain was gathered at six post-recovery time points in a triple blind fashion and statistically compared. The postoperative requirement for pain relief drugs was also examined. Results Although the injection achieved a sustained therapeutic concentration, no beneficial effect of IM betamethasone on postoperative pain or reduction in pain relief drugs was observed during the postoperative period. Indeed, the mean combined pain scores during the 2 hour postoperative period, adjusted for postoperative opioids as the major confounding factor, were higher approaching statistical significance (P = 0.056 in the treatment group. Higher pain scores were also observed for the tubal ligation patients relative to diagnostic laparoscopy. Intraoperative fentanyl treatment did not significantly lower the average pain score during the 2 hour postoperative

AIM: To investigate the role of second-look laparoscopy in patients with acute mesenteric ischemia (AMI). METHODS: Between January 2000 and November 2005, 71 patients were operated for the treatment of AMI. The indications for a second-look were low flow state, bowel resection and anastomosis or mesenteric thromboembolectomy performed during the first operation. Regardless of the clinical course of patients, the second-look laparoscopic examination was performed 72 h post-operatively at the bed side in the ICU or operating room. RESULTS: The average time of admission to the hospital after the initiation of symptoms was 3 d (range, 5 h-9 d). In 14 patients, laparotomy was performed. In 11 patients, small and/or large bowel necrosis was detected and initial resection and anastomosis were conducted. A low flow state was observed in two patients and superior mesenteric artery thromboembolectomy with small bowel resection was performed in one patient. In 13 patients, a second-look laparoscopic examination revealed normal bowel viability, but in one patient, intestinal necrosis was detected. In two of the patients, a third operation was necessary to correct anastomotic leakage. The overall complication rate was 42.8%, and in-hospital mortality rate was 57.1% (n = 6). CONCLUSION: Second-look laparoscopy is a minimally invasive, technically simple procedure that is performed for diagnostic as well as therapeutic purposes. The simplicity and ease of this method may encourage wider application to benefit more patients. However, the timing of a second-look procedure is unclear particularly in a patient with anastomosis.

Isolated tubal torsion: Successful preoperative diagnosis of five cases using ultrasound and management with laparoscopy

Directory of Open Access Journals (Sweden)

Erdem Fadıloğlu

2017-09-01

Full Text Available Our aim was to evaluate the presentation and diagnostic evaluation of patients with isolated tubal torsion and to evaluate the surgical approach to these patients. We also aimed to define the ultrasonographic diagnostic criteria. Five patients with isolated tubal torsion who were admitted to our gynecology department between January 2014 and January 2017 were evaluated and included in this study. All cases were diagnosed through ultrasonographic imaging alone. The preoperative findings of the patients were similar to those described in the literature. No further imaging modality was used for diagnosis and all patients were managed with laparoscopy. The clinical findings and ultrasonographic findings were consistent with literature. It may be difficult to preoperatively diagnose isolated tubal torsion, which is a rare clinical entity. Evaluation of these patients by an experienced sonographer and knowledge of the ultrasonographic findings of isolated tubal torsion may have vital preventive measures.

Background: Tubal disturbances often contribute to infertility. Conventional hysterosalpingography (HSG) is considered as standard in the assessment of the patency of the fallopian tubes, but requires ionizing radiation and is restricted to the imaging of endoluminal structures. Purpose: To evaluate dynamic magnetic resonance-HSG (dMR-HSG) in the diagnostic work-up in patients with infertility. Material and Methods: Thirty-seven consecutive infertile women underwent dMR-HSG: 20 ml of gadolinium-polyvidone solution (18.4 mM Dotarem 1:20 with polyvidone) were injected intracervically through a 5-Charriere balloon catheter while acquiring five consecutive flash-3D T1-weighted MR sequences with fat saturation. Two experienced readers assessed image quality and anatomic-pathologic correlations prospectively. The relevance of results was evaluated in the clinical context of each patient. Patient comfort was evaluated with a standardized questionnaire. Results: dMR-HSG was successfully completed in 33/37 patient with an average study time of 45 min. In 4 of 37 patients the catheter became dislodged during the examination, resulting in two complete diagnostic failures. Failure in another two patients was due to preliminary termination because of excessive pain and discomfort during the application of the contrast solution. The uterine cavity was completely visualized and bilateral fallopian tube patency was confirmed by dMR-HSG in 27 of 33 patients. Bilateral tubal occlusion was diagnosed in one of the remaining six patients and was confirmed by laparoscopy. Successful selective tubal catheterization was performed in one additional patient with unilateral and one patient with bilateral fallopian tube occlusion. In three cases, the catheter became dislocated at the end of the examination without demonstration of tubal patency. Since all three patients refused diagnostic laparoscopy and conventional HSG, possible bilateral occlusions of the fallopian tubes could not be

Full Text Available In this study we review our experience in using laparoscopy as a diagnostic and therapeutic tool in dealing with penetrating diaphragmatic injuries due to stab wounds and look at the feasibility of using this procedure in other similar institutions.Thirty patients, all of whom were males 20-30 years of age, presented to the surgical emergency unit of our hospital with upper abdominal and lower chest wall stab wounds between 01-05-1998 and 30-11-2006. Diagnosis of the diaphragm injury was either obvious with omentum herniating through the chest wall, or occult with confirmation of the injury at laparoscopy.All patients underwent diagnostic laparoscopy, which resulted in identification and efficient treatment of eight patients with diaphragmatic injury, and thereby laparotomy was avoided. The procedure converted to open surgery in one patient because of a small left-sided colonic tear. Laparoscopy is an efficient tool for the diagnosis and management of diaphragmatic injuries. It should be used routinely instead of exploratory laparotomy in haemodynamically stable patients with penetrating lower chest injuries.

Laparoscopy in management of appendicitis in high-, middle-, and low-income countries: a multicenter, prospective, cohort study.

Appendicitis is the most common abdominal surgical emergency worldwide. Differences between high- and low-income settings in the availability of laparoscopic appendectomy, alternative management choices, and outcomes are poorly described. The aim was to identify variation in surgical management and outcomes of appendicitis within low-, middle-, and high-Human Development Index (HDI) countries worldwide. This is a multicenter, international prospective cohort study. Consecutive sampling of patients undergoing emergency appendectomy over 6 months was conducted. Follow-up lasted 30 days. 4546 patients from 52 countries underwent appendectomy (2499 high-, 1540 middle-, and 507 low-HDI groups). Surgical site infection (SSI) rates were higher in low-HDI (OR 2.57, 95% CI 1.33-4.99, p = 0.005) but not middle-HDI countries (OR 1.38, 95% CI 0.76-2.52, p = 0.291), compared with high-HDI countries after adjustment. A laparoscopic approach was common in high-HDI countries (1693/2499, 67.7%), but infrequent in low-HDI (41/507, 8.1%) and middle-HDI (132/1540, 8.6%) groups. After accounting for case-mix, laparoscopy was still associated with fewer overall complications (OR 0.55, 95% CI 0.42-0.71, p introduction, laparoscopy could significantly improve outcomes for patients in low-resource environments.

An important yet difficult problem is qualification for surgery in elderly patients. With age the risk of comorbidities increases - multi-disease syndrome. Elderly patients suffer from frailty syndrome. Many body functions become impaired. All these factors make the elderly patient a major challenge for surgical treatment. Analysis of the possibility of developing the indications and contraindications and the criteria for surgical treatment of the elderly based on our own cases. Discussion whether there is a place for laparoscopy during surgery of the elderly in emergency room (ER) mode. The analysis was performed based on seven cases involving surgical treatment of elderly patients who were admitted to the hospital in emergency room mode. The patients were hospitalized in the General and Minimally Invasive Surgery Clinic in Olsztyn in 2016. Surgical treatment of elderly patients should be planned with multidisciplinary teams. Geriatric surgery centers should be developed to minimize the risk of overzealous treatment and potential complications. Laparoscopy should always be considered in the case of ER procedures or diagnostics. Elderly patients should not be treated as typical adults, but as a separate group of patients requiring special treatment. Due to the existing additional disease in the elderly, the frailty syndrome, any surgical intervention should be minimally invasive. The discussion about therapy should be conducted by a team of specialists from a variety of medical fields.

The optimal intraperitoneal pressure during laparoscopy is not known. Recent literature found benefits of using lower pressures, but the safety of doing abdominal surgery with low peritoneal pressures needs to be assessed. This systematic review compares low with standard pneumoperitoneum during gynecologic laparoscopy. We searched Medline, Embase, and the Cochrane Library for randomized controlled trials comparing intraperitoneal pressures during gynecologic laparoscopy. Two authors reviewed references and extracted data from included trials. Risk ratios, mean differences, and standard mean differences were calculated and pooled using RevMan5. Of 2251 studies identified, three were included in the systematic review, for a total of 238 patients. We found a statistically significant but modest diminution in postoperative pain of 0.38 standardized unit based on an original 10-point scale (95% confidence interval [CI], -0.67 to -0.08) during the immediate postoperative period when using low intraperitoneal pressure of 8 mm Hg compared with ≥ 12 mm Hg and of 0.50 (95% CI, -0.80 to -0.21) 24 hours after the surgery. Lower pressures were associated with worse visualization of the surgical field (risk ratio, 10.31; 95% CI, 1.29-82.38). We found no difference between groups over blood loss, duration of surgery, hospital length of stay, or the need for increased pressure. Low intraperitoneal pressures during gynecologic laparoscopy cannot be recommended on the behalf of this review because improvement in pain scores is minimal and visualization of the surgical field is affected. The safety of this intervention as well as cost-effectiveness considerations need to be further studied.

Full Text Available Objective: The compliance rate between the hysterosalpingography (HSG and laparoscopy (L/S results in patients who diagnosed tubal occlusion on the HSG was investigated. Also, the incidence of endometriosis was evaluated in the study population. Material and Methods: Medical records of 139 women who were underwent L/S for the investigation of the tubal occlusion were reviewed retrospectively. The concordance rate between the HSG and L/S was investigated. The incidence of endometriosis in patients with no tubal pathology was compared with patients with unilaterally and bilaterally tubal occlusion. Results: Mean age of the women was 31.8±5.7years, mean BMI was measured as 24.6±4.6 kg/m2, and gravida 0 (0-5, mean infertility period was 30.7±3.7 months. Tubal occlusion was confirmed after the L/S in 38.8% of the patients (n=38 who has unilaterally tubal occlusion on the HSG. However, 58.8% (n=20 of the patients who were diagnosed as bilaterally tubal occlusion on the HSG was confirmed with the L/S. The misdiagnosis rate of the HSG was significantly high in women with unilaterally tubal occlusions compared with bilaterally tubal occlusions [(respectively, 61.2%, 51.2% (p: 0.001]. Endometriosis was observed in 28.4% of the patients who had patent tubes and in 13.9% of the patients in the unilaterally tubal occlusion group and and in 22.7% of the patients in the bilaterally tubal occlusion group. But the difference was not statistically significant when groups were compared according to the rate of endometriosis (p=0.24. Conclusion: HSG is the first step diagnostic test for the assessment of the fallopian tubes. Although L/S is more invasive technique than HSG, L/S with chromopertubation is the gold standard test for identifying periadnexal adhesive disease and endometriosis.

2017-01-01

Full Text Available Adenomyosis or endometriosis genitalis interna is a frequent benign disease of women in fertile age. It causes symptoms like bleeding disorders and dysmenorrhea and seems to have a negative effect on fertility. Adenomyosis can be part of a complex genital and extragenital endometriosis but also can be found as a solitary uterine disease. While peritoneal endometriosis can be easily diagnosed by laparoscopy with subsequent biopsy, the determination of adenomyosis is difficult. In the following literature review, the diagnostic methods clinical history and symptoms, gynecological examination, 2D and 3D transvaginal ultrasound, MRI, hysteroscopy, and laparoscopy will be discussed step by step in order to evaluate their predictive value in the diagnosis of adenomyosis.

This meta-analysis aimed to evaluate the prognosis and recurrence of apparent early-stage ovarian tumors treated with laparoscopy compared with laparotomy. Clinical studies published in English were retrieved from the computerized databases Medline and Embase. A meta-analysis was performed to investigate the differences in the efficacy and safety of laparoscopy versus laparotomy in terms of postoperative complications, lengths of hospital stay, recurrence rates, and disease-free survival times using the random effects model. The studies were independently reviewed by two investigators. Data from the eligible studies were extracted, and the meta-analysis was performed using the Comprehensive Meta-Analysis program, version 2 (CMA-2; Biostat, Englewood, NJ, USA). A total of 8 studies were included in the analysis. The results showed that laparoscopic surgery was significantly associated with lower rates of complications (OR = 0.433, P = 0.019) and shorter postoperative hospital stays (weighted mean difference [WMD] = −0.974, P < 0.001). There was no significant difference in the rates of recurrence (OR = 0.707, P = 0.521) between patients with apparent early-stage ovarian tumors who were treated using laparoscopy and those who underwent laparotomy. No publication bias was detected. Laparoscopic surgery shows favorable prognostic outcomes in terms of postoperative complication rates and postoperative hospital stay durations. Further studies with longer follow-up periods are required to confirm recurrence and survival outcomes after laparoscopic surgery in patients with apparent early-stage ovarian tumors

Full Text Available The authors report a case of intra-abdominal testicular torsion, where laparoscopy has been useful for diagnosis and surgical management. A boy was presented with a left impalpable testis. Laparoscopy revealed a twisted spermatic cord at the inlet pelvis, which ended in a testicular remnant located in the sub-umbilical area. After orchiectomy, the pathologist confirmed testicular atrophy. Diagnosis of intra-abdominal testicular torsion should be considered in patients with impalpable testis and abdominal pain, but could not be excluded in those with no symptoms.

To evaluate the impact of obesity on the outcomes of surgical treatment for endometrial cancer in general and also comparing laparoscopic and open abdominal approach. Retrospective case-control study (Canadian Task Force classification II-1). Obstetrics and Gynecology Department, University of Insubria, Varese, Catholic University of the Sacred Heart, Rome, International School of Surgical Anatomy, Sacred Heart Hospital, Negrar, and Sant'Orsola-Malpighi Hospital, Bologna, Italy. Data of consecutive patients who underwent surgery for endometrial cancer in 4 centers were reviewed. Univariate and multivariable analyses were performed. Adjustment for potential selection bias in surgical approach was made using propensity score (PS) matching. Laparoscopic or open surgical treatment for endometrial cancer. A total of 1266 patients were included, including 764 in the laparoscopy group and 502 in the open surgery group. A total of 391 patients (30.9%) were obese, including 238 (18.8%) with class I obesity, 89 (7%) with class II obesity, and 64 (5.1%) with class III obesity. The total number of complications, risk of wound complications, and venous thromboembolic events were higher in obese women compared with nonobese women. Blood transfusions, incidence/severity of postoperative complications, and postoperative hospital stay were significantly higher in the open surgery group compared with the laparoscopy group, irrespective of obesity. These differences remained significant in both multivariable analysis and PS-matched analysis. The percentage of patients who received lymphadenectomy declined significantly in patients with BMI ≥40 in both the laparoscopy and open surgery groups. Conversions from the initially intended minimally invasive approach to open surgery were 1.1% to 2.2% for women with BMI obese women in the laparoscopic group. Laparoscopy for endometrial cancer retains its advantages over open surgery, even in obese patients. However, operating on obese

Full Text Available Ectopic pancreatic tissue is an uncommon developmental anomaly. The condition mostly occurs in the gastrointestinal tract and is usually asymptomatic. It rarely causes symptoms of inflammation, bleeding and perforation, and has potential for malignant change. Though it is an uncommon condition, cases of ectopic pancreas have been reported worldwide. Preoperative diagnosis of ectopic pancreas is challenging because of its nonspecific symptoms and signs. Owing to the revolution of minimally invasive surgery, submucosal tumors of the stomach can be resected by laparoscopic techniques. We have earlier reported on a case of ectopic pancreas in the stomach treated by robotics-assisted laparoscopic wedge resection. Herein, we report a case of ectopic pancreas in the prepyloric region of the stomach. A 44-year-old female presented with a two-week history of epigastralgia with radiation to the back. She received endoscopy check-up which disclosed a mass in the stomach. By endoscopic findings, a submucosal lesion in the prepyloric region with umbilical folding on the mucosa was identified. The umbilical folding on the mucosa hint the orifice of the duct of ectopic pancreas into the gastric mucosa suggestive of ectopic pancreas. Contrast-enhanced abdominal computed tomography showed a 5 cm cystic mass with heterogeneous content. To sum it up, the patient was diagnosed as ectopic pancreas in the stomach. She underwent laparoscopy-assisted antrectomy with Billroth I anastomosis (excision of the antrum and prepyloric region with reconstruction of gastrointestinal continuity by gastroduodenostomy and had an uneventful hospitalization course. The histopathology of the resected tumor demonstrated ectopic pancreatic tissue in the gastric wall. To the best of our knowledge, excision of gastric ectopic pancreas using laparoscopy-assisted antrectomy with Billroth I anastomosis has never been reported in the literature.

Evidence supports early laparoscopic cholecystectomy for acute cholecystitis. Differences in treatment patterns between the USA and UK, associated outcomes and resource utilization are not well understood. In this retrospective, observational study using national administrative data, emergency patients admitted with acute cholecystitis were identified in England (Hospital Episode Statistics 1998-2012) and USA (National Inpatient Sample 1998-2011). Proportions of patients who underwent emergency cholecystectomy, utilization of laparoscopy and associated outcomes including length of stay (LOS) and complications were compared. The effect of delayed treatment on subsequent readmissions was evaluated for England. Patients with a diagnosis of acute cholecystitis totaled 1,191,331 in the USA vs. 288 907 in England. Emergency cholecystectomy was performed in 628,395 (52.7% USA) and 45,299 (15.7% England) over the time period. Laparoscopy was more common in the USA (82.8 vs. 37.9%; p USA. Overall incidence of bile duct injury was higher in England than the USA (0.83 vs. 0.43%; p USA and England. Despite best evidence, index admission laparoscopic cholecystectomy is performed less in England, which significantly impacts subsequent healthcare utilization.

The aim of the present study is to evaluate mental workload and fatigue in fingers, hand, arm, shoulder in single-incision laparoscopic surgery (SILS) and multiport laparoscopy. Volunteers performed chosen tasks by standard laparoscopy and SILS. Time to complete tasks and finger and hand strength were evaluated. Lateral, tripod, and pulp pinch strengths were measured. Hand dexterity was determined by pegboard. Electromyography recordings were taken from biceps and deltoid muscles of both extremities. The main outcome measurement was median frequency (MF) slope. NASA-TLX was used for mental workload. Time to complete laparoscopic tasks were longer in the SILS group (P NASA-TLX score was 73 ± 13.3 and 42 ± 19.5 in SILS and multiport laparoscopy, respectively (P < .01). Mental demand, physical demand, temporal demand, performance, effort, and frustration were, respectively, scored 10.7 ± 3.8, 11.7 ± 3.5, 12.2 ± 2.7, 11 ± 3, 13.6 ± 2.7, and 13.5 ± 2.8 in SILS and 6.3 ± 3.1, 6.6 ± 3.3, 7.3 ± 3.3, 7.1 ± 4.1, 7.9 ± 3.9, and 6.6 ± 3.8 in standard laparoscopy (P < .01). SILS is mentally and physically demanding, particularly on arms and shoulders. Fatigue of big muscles, effort, and frustration were major challenges of SILS. Ergonomic intervention of instruments are needed to decrease mental and physical workload. © The Author(s) 2014.

2010-01-01

Artificial tactile sensing is a novel method for obtaining different characteristics of a hard object embedded in a soft tissue. In this regard, artificial palpation is one of the most valuable achievements of artificial tactile sensing that can be used in various fields of medicine and more specifically in surgery. In this study, considering the present problems and limitations in kidney-stone-removal laparoscopy, a new application will be presented for artificial tactile sensing approach. Having imitated surgeon's palpation during open surgery and modeled it conceptually, indications of stone existence that appear on the surface of kidney (due to exerting mechanical load) were determined. A number of different cases were created and solved by the software. Using stress distribution contours and stress graphs, it is illustrated that the created stress patterns on the surface of kidney not only show the existence of stone inside, but also its exact location. In fact, the reliability and accuracy of artificial tactile sensing method in detection of kidney stone during laparoscopy is demonstrated by means of finite element analysis. Also, in this paper, the functional principles of tactile system capable of determining the exact location of stone during laparoscopy will be presented.

Analysis of perioperative outcomes and survival of patients with recurrent ovarian cancer undergoing secondary cytoreduction by robotics, laparoscopy, or laparotomy. Retrospective analysis of 52 selected patients with recurrent ovarian cancer undergoing secondary cytoreduction by laparoscopy (9), laparotomy (33) or robotics (10) between January 2006 and December 2010. Comparison was made by a total of 21 factors including age, BMI, number of previous surgeries, tumor type and grade, number of procedures, and 15 types of procedures performed at secondary cytoreduction. For all patients, the mean operating time was 213.8 min, mean blood loss 657.4 ml; and mean hospital stay 7.5 days. Complete debulking was achieved in 75% of patients. Postoperative complications were noted in 36.5% of patients. Overall and progression-free survival at 3-years were 58.8% and 34.1%, respectively. Laparoscopy and robotics had reduced blood loss and hospital stay, while no differences were observed among the three groups for operating time, complications, complete debulking, and survival. Selected patients with recurrent ovarian cancer benefit from a laparoscopic or robotic secondary cytoreduction without compromising survival. Robotics and laparoscopy provide similar perioperative outcomes, and reduced blood loss and shorter hospital stay as compared to laparotomy. Laparotomy seems preferable for patients with widespread peritoneal implants, multiple sites of recurrence, and/or extensive adhesions. Copyright © 2013 Elsevier Inc. All rights reserved.

The experiences of special X-ray diagnostics of female genitals are described, that were made in 41 children within a period of 12 years. The superiority of the X-ray-technique arises from the impossibility of the manual examination in newborn and infants and the avoidance of diagnostic techniques like laparoscopy or laparotomy. All the examination techniques are described. In intersexualmarked patients the discrimination into six types after Shopfner is preferred. Malformations and tumours are dealt with briefly. The relations between skeleton and female genitals are pointed out at the example of the gonadal dysgenesis. (orig.) [de

Full Text Available INTRODUCTION: Dysphagia is the important symptom in achalasia, and surgery is the most common treatment. The Heller-Pinotti technique is the method preferred by Brazilian surgeons. For many years, this technique was performed by laparotomy, and now the laparoscopic method has been introduced. The objective was to evaluate the immediate and long-term results of patients submitted to surgery by either laparotomy or laparoscopy. MATERIALS AND METHODS: A total of 67 patients submitted to surgery between 1994 and 2001 with at least 5 years of follow-up were evaluated retrospectively and divided into two groups: laparotomy (41 patients and laparoscopy (26 patients. Chagas was the etiology in 76.12% of cases. Dysphagia was evaluated according to the classification defined by Saeed et al. RESULTS: There were no cases of conversion to open surgery. The mean duration of hospitalization was 3.32 days for laparotomy and 2.54 days for laparoscopy (p<0.05. An improvement in dysphagia occurred with both groups reporting good or excellent results (laparotomy: 73.17% and laparoscopy: 73.08%. Mean duration of follow-up was 8 years. CONCLUSIONS: There was no difference between the two groups with respect to relief from dysphagia, thereby confirming the safety and effectiveness of the Heller-Pinotti technique, which can be performed by laparotomy or laparoscopy, depending on the surgeon's experience.

Full Text Available Objective: To assess the findings and usefulness of hysterosalpingography as a routine investigation in the fertility workup prior to selective laparoscopy. Design: Descriptive retrospective study. Setting: A university hospital in the north of Jordan. Subjects: All hysterosalpingographies performed in the period between 1st January and 31 December 2008. Outcome measures: Detection of uterine and fallopian tube abnormalities and their correlation with laparoscopic findings. Results: During the study period, 281 infertile women underwent hysterosalpingography with no post procedural complications. The mean (SD age was 31.5 (5.91 years. Mean (SD duration of infertility was 4 (3.44 years. Infertility was reported as primary and secondary by 119 (42.3 % and 162 (57.6 %, respectively. Altogether 281 patients and 562 tubes were examined. Of those, 402 were patent and 160 occluded. There was only one woman in whom peritubal adhesions were diagnosed. Because of hysterosalpingographically diagnosed tubal occlusion, 46 women (16.4 % were referred for laparoscopy. Eight (17.3% of them were treated with unilateral salpingectomy and 28 (60.8% with bilateral salpingectomy. Salpingolysis was performed for 7 (15.2% women, and 3 (6.7% women had untreatable adhesions. The concordance was 71.7%. The sensitivity of HSG was 80%, the specificity 50%, the negative predictive value 61% and the positive predictive value 71%. Of the total of 281 women, 30 (10.7% conceived within 1 - 11 months after the hysterosalpingography. Conclusions: The very high abnormal predictive value of hysterosalpingography in the diagnosis of tubal occlusion suggests that this procedure could be performed as a screening examination.

Full Text Available Aim: To evaluate an alternative way of reducing intussusceptions under laparoscopic guidance. Materials and Methods: This is a retrospective observational study of children who underwent laparoscopy-assisted hydrostatic in situ reduction of intussusceptions (LAHIRI. Under general anesthesia with laparoscopic vision, warm saline was infused into the rectum with a 16-18 F Foley catheter and a drip set till the intussusception was reduced. Results: Eleven patients [age 7.8 (±2.8 months] were operated over a period of 1 year. Ten (90.9% patients had ileocolic intussusception, which got completely reduced, but one (9% had ileo-ileocolic intusussception, in whom manual reduction by extending the subumbilical incision was required to reduce the ileoileal part. The mean duration of surgery was 38.5 (±6.6 min. No patient had bowel ischemia and there were no intra- or postoperative complications. Conclusions: LAHIRI appears to be an effective and safe technique in children. Specific advantages are that it is performed in a controlled environment in the operating room, avoids patient apprehension and discomfort, avoids bowel handling, provides a safe opportunity to create higher intraluminal pressure, ensures visual assessment of bowel vascularity and completeness of reduction.

This study aimed to evaluate the impact on perioperative and medium-term oncologic outcomes of the implementation of laparoscopy into a preexisting oncologic setting. Data from consecutive 736 patients undergoing surgery for apparent early stage gynecological malignancies (endometrial, cervical, and adnexal cancers) between 2000 and 2011 were reviewed. Complications were graded per the Accordion classification. Survival outcomes within the first 5 years were analyzed using Kaplan-Meier method. Overall, 493 (67%), 162 (22%), and 81 (11%) had surgery for apparent early stage endometrial, cervical, and adnexal cancer. We assisted at an increase of the number of patients undergoing surgery via laparoscopy through the years (from 10% in the years 2000-2003 to 82% in years 2008-2011; P 0.05). The introduction of laparoscopy did not adversely affect medium-term (within 5 years) survival outcomes of patients undergoing surgery for apparent early stage cancers of the endometrium, uterine cervix, and adnexa (P > 0.05 log-rank test). The introduction of laparoscopy into a preexisting oncologic service allows an improvement of standard of care due to a gain in perioperative results, without detriments of medium-term oncologic outcomes.

laparoscopia revelou obstrução bilateral. Em 15 casos (65,2% em que a HSG havia demonstrado obstrução bilateral, a laparoscopia foi normal ou revelou apenas obstrução unilateral. CONCLUSÕES: a laparoscopia demonstrou sua relevância diagnóstica e terapêutica revelando-se fundamental na clarificação do status tubo-peritoneal. Permitiu a realização concomitante de atos terapêuticos, possibilitando a definição da melhor estratégia terapêutica no casal infértil.PURPOSE: to evaluate the contribution of diagnostic laparoscopy to approach the infertile couple. METHODS: retrospective analysis of 86 consecutive cases of patients who were accompanied in the infertility appointments and were submitted to diagnostic laparoscopy from January 2004 to December 2006. Eighty-two of these patients had been submitted to hysterosalpingography (HSG prior to laparoscopy. The laparoscopic findings were analyzed, as well as the accessory procedures, and the results of the hysterosalpingography and of the laparoscopy were correlated. Statistical analysis was performed by the use of the Statistical Package for the Social Sciences 15. The sensitivity and the specificity of HSG were determined and the confidence intervals were calculated with an alpha error of 0.05 (95%CI. RESULTS: the laparoscopy revealed 21 cases of endometriosis (24.4%, 14 cases of uni/bilateral inflammatory disease of the salpinx (16.3%, and 16 cases of pelvic inflammatory disease (18.6%. Adhesiolysis and ablation of endometrial lesions were performed in eight patients. There were also other accessory procedures: two salpingostomies, two paraovarian cystectomies, two ovarian cystectomies and three ovarian drillings. The tubal patency test during laparoscopy was normal in 44 cases (53%, revealed unilateral obstruction in 21 cases (25.3% and bilateral obstruction in 17 cases (20.5%. The results of the hysterosalpingography were similar to those of the laparoscopy in 44 out of the 82 cases (53.7%. HSG sensitivity was

Posture, vision, and instrumentation limitations are the main predicaments of conventional laparoscopy. To combine the ETHOS surgical chair, the three-dimensional laparoscope, and the Radius Surgical System manipulators, and compare the system with conventional laparoscopy and da Vinci in terms of task completion times and discomfort. Fifteen trainees performed the three main laparoscopic suturing tasks of the Heilbronn training program (IV: simulation of dorsal venous complex suturing; V: circular suturing of tubular structure; and VI: urethrovesical anastomosis) in a pelvi trainer. The tasks were performed conventionally, utilizing the three devices, and robotically. Task completion times were recorded and the surgeon discomfort was evaluated using questionnaires. Task completion times were compared using nonparametric Wilcoxon signed rank test and ergonomic scores were compared using Pearson chi-square test. The use of the full laparoscopic set (ETHOS chair, three-dimensional laparoscopic camera, Radius Surgical System needle holders), resulted in a significant improvement of the completion time of the three tested tasks compared with conventional laparoscopy (psystem nullified heavy discomfort for Tasks IV and V and minimized it (6.7%) for the most demanding Task VI. Especially for Task VI, all trainees gained benefit, by using the system, in terms of task completion times and discomfort. The limited trainee robotic experience and the questionnaire subjectivity could be a potential limitation. The ergonomic laparoscopic system offers significantly improved task completion times and ergonomy than conventional laparoscopy. Furthermore, it demonstrates comparable results to robotic surgery. The study was conducted in a pelvi trainer and no patients were recruited. Copyright © 2016 European Association of Urology. Published by Elsevier B.V. All rights reserved.

Gastric carcinoma is derived from epithelial cells in the gastric mucosa. We reported an extremely rare case of submucosal gastric carcinoma originating from the heterotopic submucosal gastric gland (HSG) that was safely diagnosed by laparoscopy and endoscopy cooperative surgery (LECS). A 66-year-old man underwent gastrointestinal endoscopy, which detected a submucosal tumor (SMT) of 1.5 cm in diameter on the lesser-anterior wall of the upper gastric body. The tumor could not be diagnosed histologically, even by endoscopic ultrasound-guided fine-needle aspiration biopsy. Local resection by LECS was performed to confirm a diagnosis. Pathologically, the tumor was an intra-submucosal well differentiated adenocarcinoma invading 5000 μm into the submucosal layer. The resected tumor had negative lateral and vertical margins. Based on the Japanese treatment guidelines, additional laparoscopic proximal gastrectomy was curatively performed. LECS is a less invasive and safer approach for the diagnosis of SMT, even in submucosal gastric carcinoma originating from the HSG. PMID:26306144

The diagnostic methods of tubal factor in infertility have been presented. In details have been discussed PJ, PK HSG and pelviscopy. These examinations themselves constitute the basic ones in infertility. We turned our attention into technical details and possible mistakes which may occur at the time of performing them, these misinterpretations may lead to absolutely wrong conclusion and diagnosis. Authors have wide experience in performing the discussed examinations and this allows them to share their opinion. Over the years several thousand of PK and HSG examinations have been carried out and also 1000 laparoscopies. (author)

The purpose of the present study was to investigate on the acceptance and frequency of laparoscopic surgery for the management of acute and chronic bowel obstruction in a general patient population in German hospitals. To receive an authoritative opinion on laparoscopic treatment of bowel obstruction in Germany, a cross-sectional online study was conducted. We designed an online-based survey, supported by the German College of Surgeons (Berufsverband der Deutschen Chirurgen, BDC) to get multi-institutional-based data from various level providers of patient care. Between January and February 2014, we received completed questionnaires from 235 individuals (16.7 %). The participating surgeons were a representative sample of German hospitals with regard to hospital size, level of center size, and localization. A total of 74.9 % (n = 176) of all responders stated to use laparoscopy as the initial step of exploration in expected bowel obstruction. This procedure was highly statistically associated with the frequency of overall laparoscopic interventions and laparoscopic experience. The overall conversion rate was reported to be 29.4 %. This survey, investigating on the use of laparoscopic exploration or interventions in bowel obstruction, was able to show that by now, a majority of the responding surgeons accept laparoscopy as an initial step for exploration of the abdomen in the case of bowel obstruction. Laparoscopy was considered to be at least comparable to open surgery in an emergency setting. Furthermore, data analysis demonstrated generally accepted advantages and disadvantages of the laparoscopic approach. Indications for or against laparoscopy are made after careful consideration in each individual case.

The objective of this Chapter was to investigate the feasibility and outcome of gasless laparoscopy under regional anesthesia. A prospective evaluation of Lift-(gasless) laparoscopic procedures under regional anesthesia (Canadian Task Force classification II-1) was done at three endoscopic gynecology centers (franchise system of EndGyn(r)). Sixty-three patients with gynecological diseases comprised the cohort. All patients underwent Lift-laparoscopic surgery under regional anesthesia: 10 patients for diagnostic purposes, 17 for surgery of ovarian tumors, 14 to remove fibroids, and 22 for hysterectomies. All patients were operated without conversion to general anesthesia and without perioperative or anesthesiologic complications. Lift-laparoscopy under regional anesthesia can be recommended to all patients who desire laparoscopic intervention without general anesthesia. For elderly patients, those with cardiopulmonary risks, during pregnancy, or with contraindications for general anesthesia, Lift-laparoscopy under regional anesthesia should be the procedure of choice.

Full Text Available Laparoscopic appendectomy is being performed increasingly, worldwide. The laparoscopic approach is associated witha lower complication rate and a shorter period of disability but some major complications still occur. We present a caseof a 22-year-old woman who underwent laparoscopic appendectomy for acute appendicitis. In 3 weeks time after surgery,after physical activity the patient presented acute abdomen. Exploratory laparoscopy revealed peritonitis causedby caecal fistula. Laparoscopic lavage and drainage of the peritoneal cavity with formal caecostomy was performed.The postoperative course was uneventful. The stoma was closed in 6 months’ time without other complications. Inour opinion laparoscopy is proven to be a safe and good option for diagnostics and treatment of some complicationsof appendectomy.

Retroperitoneoscopic nephrectomy is less invasive than open nephrectomy, and is an alternative surgical procedure for renal tumors and upper urothelial tumors. We evaluated the efficacy of virtual computerized tomography laparoscopy (VCTL) as a navigator for retroperitoneoscopic nephrectomy to ascertain the correct anatomy of the renal hilum pre-operatively under the retroperitoneoscopic view. Seventy-three kidneys with localized renal tumors (n=44), upper urothelial tumors (n=23), or benign renal disease (n=6) underwent multidetector-row CT. VCTL was carried out by the volume-rendered technique. The findings were compared with those of real retroperitoneoscopy. After the operation, each operator scored 1 to 5 in evaluating the usefulness of virtual retroperitoneoscopy (score 5 indicated very useful). The percentages of renal arteries depicted by VCTL compared with those noted during real surgery were 93% for kidneys with renal tumors, 100% for upper urothelial tumors and 83% for benign renal disease. Two renal arteries of 2 kidneys were not detected by virtual imaging. These were about 1 mm in diameter and directly branched from the aorta, however retroperitoneoscopic nephrectomy was performed uneventfully. VCTL depicted all the renal veins. The anatomy of the renal hilum seen on VCTL and real retroperitoneoscopy was identical, without the minor angle deviation caused by drawing the kidney during the operation. The average score for the usefulness of VCTL was 4.1, ranging from 3 to 5. The accurate surgical anatomy of the renal hilum could be predicted in almost all patients pre-operatively. VCTL is an excellent navigator for retroperitoneoscopic nephrectomy. (author)

Proper staging is critical to the management of pancreatic ductal carcinoma (PDAC). Laparoscopy has been used to stage patients without gross metastatic disease with variable success. We aimed to identify the frequency of patients diagnosed by laparoscopy with occult metastatic disease. Also, we looked for variables related to a higher chance of occult metastasis. Patients with PDAC submitted to staging laparoscopy either immediately before pancreatectomy or as a separate procedure between January 2010 and December 2016 were included. None presented gross metastatic disease at initial staging. We used logistic regression to search for variables associated with metastatic disease. The study population consisted of 63 patients. Among all patients, nine (16.7%) had occult metastases at laparoscopy. Unresectable tumor (Odds ratio = 18.0, P = 0.03), increasing tumor size (Odds ratio = 1.36, P = 0.01), and abdominal pain (Odds ratio = 5.6, P = 0.04) significantly predicted the risk of occult metastases in univariate analysis. In multivariate analysis, only tumor size predicted the risk of occult metastases. Laparoscopy remains a valuable tool in PDAC staging. Patients with either large or unresectable tumors, or presenting with abdominal pain present the highest risk for occult intra-abdominal metastases. © 2018 Wiley Periodicals, Inc.

AIM: To evaluate the nature of the "learning curve" for laparoscopy-assisted distal gastrectomy (LADG) with systemic lymphadenectomy for early gastric cancer. METHODS: The data of 90 consecutive patients with early gastric cancer who underwent LADG with systemic lymphadenectomy between April 2003 and November 2004 were reviewed. The 90 patients were divided into 9 sequential groups of 10 cases in each group and the average operative time of these 9 groups were determined. Other learning indicators, such as transfusion requirements, conversion rates to open surgery, postoperative complication, time to first flatus, and postoperative hospital stay, were evaluated. RESULTS: After the first 10 LADGs, the operative time reached its first plateau (230-240 min/operation) and then reached a second plateau (＜200 min/operation) for the final 30 cases. Although a significant improvement in the operative time was noted after the first 50 cases, there were no significant differences in transfusion requirements, conversion rates to open surgery, postoperative complications, time to first flatus, or postoperative hospital stay between the groups. CONCLUSION: Based on operative time analysis, this study show that experience of 50 cases of LADG with systemic lymphadenectomy for early gastric cancer is required to achieve optimum proficiency.

Reexpansion Pulmonary Edema following Laparoscopy-Assisted Distal Gastrectomy for a Patient with Early Gastric Cancer: A Case Report

Directory of Open Access Journals (Sweden)

Kazuhito Yajima

2012-01-01

Full Text Available We report here a case of reexpansion pulmonary edema following laparoscopy-assisted distal gastrectomy (LADG for early gastric cancer. A 57-year-old Japanese woman with no preoperative comorbidity was diagnosed with early gastric cancer. The patient underwent LADG using the pneumoperitoneum method. During surgery, the patient was unintentionally subjected to single-lung ventilation for approximately 247 minutes due to intratracheal tube dislocation. One hour after surgery, she developed severe dyspnea and produced a large amount of pink frothy sputum. Chest radiography results showed diffuse ground-glass attenuation and alveolar consolidation in both lungs without cardiomegaly. A diagnosis of pulmonary edema was made, and the patient was immediately intubated and received ventilatory support with high positive end-expiratory pressure. The patient gradually recovered and was weaned from the ventilatory support on the third postoperative day. This case shows that single-lung ventilation may be a risk factor for reexpansion pulmonary edema during laparoscopic surgery with pneumoperitoneum.

To compare the diagnostic accuracy of ultrasonography (US), F18-fluorodeoxyglucose positron emission tomography/CT (PET/CT), contrast enhanced CT (CECT), serum anti-thyroid antibody for detecting Hashimoto's thyroiditis in thyroid cancer patients who underwent neck surgery. A total of 150 patients with suspicious for thyroid cancer, who had previously undergone US guided needle aspiration of thyroid, were evaluated with the use of US, PET/CT, CECT and serum anti-thyroid antibody. The four studies were performed within two months before neck surgery. Hashimoto's thyroiditis was confirmed by histopathological results. The diagnostic accuracy of US, PET/CT, CECT and serum anti-thyroid antibody were calculated statistically. Hashimoto's thyroiditis was diagnosed in 51 out of the 150 patients, following neck surgery. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of US were 76.5%, 92.9%, 84.8%, 88.5%, and 87.3%, respectively. The corresponding values of PET/CT were 37.3%, 96.0%, 82.6%, 74.8%, and 76.0%, and CECT were 62.7%, 89.9%, 76.2%, 82.4%, and 80.7%, and serum anti-thyroid antibody level were 90.2%, 93.9%, 88.5%, 94.9%, and 92.7%, respectively. McNemar test revealed significant difference among PET/CT and others, but no significant differences among US, CECT and serum anti-thyroid antibody. Overall, serum anti-thyroid antibody showed most accurate diagnostic performance. In detecting Hashimoto's thyroiditis, serum anti-thyroid antibody showed higher diagnostic accuracy than others. US also showed relatively high diagnostic accuracy.

Blunt hollow viscus perforations (HVP) due to abdominal contusions (AC), although rare, are difficult to diagnose early and are associated with a high mortality. Our paper analyses retrospectively data from patients operated for HVP between January 2005 and January 2009, the efficiency of different diagnostic tools, mortality and prognostic factors for death. There were 62 patients operated for HVP, 14 of which had isolated abdominal contusion and 48 were poly trauma patients. There were 9 women and 53 men, the mean age was 41.5 years (SD: +17,9), the mean ISS was 32.94 (SD: +15,94), 23 patients had associated solid viscus injuries (SVI). Clinical examination was irelevant for 16 of the 62 patients, abdominal Xray was false negative for 30 out of 35 patients and abdominal ultrasound was false negative for 16 out of 60 patients. Abdominal CT was initially false negative for 7 out of 38 patients: for 4 of them the abdominal CT was repeated and was positive for HVP, for 3 patients a diagnostic laparoscopy was performed. Direct signs for HVP on abdominal CT were present for 3 out of 38 patients. Diagnostic laparoscopy was performed for 7 patients with suspicion for HVP, and was positive for 6 of them and false negative for a patient with a duodenal perforation. Single organ perforations were present in 55 cases, multi organ perforations were present in 7 cases. There were 15 deaths (15.2%), most of them caused by haemodynamic instability (3 out of 6 patients) and associated lesions: SOL for 9 out of 23 cases, pelvic fracture (PF) for 6 out of 14 patients, craniocerebral trauma (CCT) for 12 out of 33 patients.Multivariate analysis showed that the prognostic factors for death were ISS value (p = 0,023) and associated CCT (odds ratio = 4,95; p = 0,017). The following factors were not confirmed as prognostic factors for death: age, haemodynamic instability, associated SVI, thoracic trauma (TT), pelvic fractures (PF), limbs fractures (LF) and admission-operation interval

Full Text Available Introduction : Celiac trunk (CT compression syndrome caused by the median arcuate ligament (MAL is a rarely diagnosed disease because of its nonspecific symptoms, which cause a delay in the correct diagnosis. Intestinal ischemia occurs, which causes symptoms of abdominal angina. One method of treatment for this disease is surgical release of the CT – the intersection of the MAL. Laparoscopy is the first step of the hybrid technique combined with percutaneous angioplasty and stenting of the CT. Aim: To demonstrate the usefulness and advantages of the laparoscopic approach in the treatment of Dunbar syndrome. Material and methods : Between 2013 and 2016 in the General and Minimally Invasive Surgery Department of the Medical Sciences Faculty of the University of Warmia and Mazury in Olsztyn, 6 laparoscopic procedures were performed because of median arcuate ligament syndrome. During the laparoscopy the MAL was cut with a harmonic scalpel. One month after laparoscopy 5 patients had Doppler percutaneous angioplasty of the CT with stent implantation in the Vascular Surgery Department in Pomeranian Medical University in Szczecin. Results : In one case, there was a conversion of laparoscopic surgery to open due to unmanageable intraoperative bleeding. In one case, postoperative ultrasound examination of the abdominal cavity demonstrated the presence of a large hematoma in the retroperitoneal space. All patients reported relief of symptoms in the first days after the operation. Conclusions : The hybrid method, combining laparoscopy and angioplasty, seems to be a long-term solution, which increases the comfort of the patient, brings the opportunity for normal functioning and minimizes the risk of restenosis.

Material and methods: One hundred and sixty-eight patients who were diagnosed laparoscopically in 2008and 2009 were studied retrospectively. Frequency of the causes and findings were determined. Results: From the whole group of 285 women who underwent laparoscopy, 168 patients (59% were diagnosedlaparoscopically. Among this group 145 women (83% were referred for the invasive diagnostic proceduredue to primary infertility. The average age of primary infertile women was 30.8 years, secondary infertile women32.6 years. Endometriosis was diagnosed in 113 patients (67%. Thirty-eight women (23% were found to have Zroatubal disease; among these patients 36% had bilateral tubal blockage. Dense pelvic adhesions were morefrequent in secondary infertile women. Adhesiolysis was conducted in 26% of examined patients. Conclusions: Diagnostic laparoscopy is a valuable technique for complete assessment of female infertility.Endometriosis is the most probable cause of infertility in two of three women. Other common factors responsiblefor infertility are tubal disease, adhesions and polycystic ovaries.

The role of laparoscopy in the multimodality treatment of colorectal cancer.

Ten years after the first reports of laparoscopic techniques in colorectal surgery the precise role for these approaches in future colorectal practice as still to be defined. However, it seems most unlikely that the application is going to disappear. Laparoscopic colectomy is undoubtedly a complex. time-consuming procedure and it is clear that the technique is intolerant of difficult cases and will likely remain thus. Therefore. the potential advantages of laparoscopy do not as yet appear to be attainable across the board in colorectal resection. Such generalized advantage may, however, be tantalizingly close. Although many studies have failed to show major benefits for laparoscopy in terms of postoperative recovery, it must be remembered that most of these have been of insufficient statistical power to settle the issue. What is clear to all involved in the field is that very many patients do gain major benefit from the minimally invasive approach. The challenge for the future lies in developing the technology to such a point that these benefits for patients are more reproducible. The requirement for a significant abdominal incision to deliver an intact specimen represents a significant hurdle in this regard. The importance of pathological staging for colorectal cancer at present mandates retrieval of an intact specimen. It is of course possible that radiological staging may develop to such a point that surgeons need only remove the lesion with minimal attention to lymphadenectomy. Alternatively, new adjuvant therapies may arrive that, by virtue of increased efficacy and low side-effect profiles, may be applicable to all but the earliest lesions. Finally, increasing health awareness and application of screening programs may lead to a preponderance of large polyps and preinvasive lesions for which a more limited resection may be appropriate. Obviously these scenarios remain almost entirely speculative. However, the trend towards less invasive local therapy for

A 69-year-old man with right upper quadrant abdominal pain and fever was referred to our hospital. He had a history of asbestosis exposure. Computed tomography(CT)revealed a mass at the right subhepatic space, and an antibiotic was administered after a diagnosis of an abdominal abscess. However, the patient did not respond to the treatment, and finally, exploratory laparoscopy was performed. A sheet of combined white nodules surrounding the right lobe of the liver was found, and the mass was continuous with the covering particles. Biopsy of the mass and immunohistochemical examination was performed. The resulting diagnosis was diffuse epithelial malignant peritoneal mesothelioma(MPM). Postoperative systematic chemotherapy of pemetrexed and cisplatin was administered. Laparoscopy was useful to evaluate the distribution of the MPM, which led to adequate therapeutic determination.

From February 1982-June 1986, 25 consecutive patients with surgical stage I endometrial adenocarcinoma (no evidence of metastasis at surgery or occult cervical or adnexal involvement on histopathologic review) and malignant peritoneal cytologic washings were treated with progesterone therapy. Twenty-two patients have undergone a second look laparoscopy and repeat cytologic washings, one of those also underwent a third look laparoscopy. Two patients refused second look laparoscopy, and in a third patient laparoscopy was medically contraindicated; all three have no evidence of disease (NED) at 15, 46, and 64 months respectively and are off therapy. Of the 22 patients who underwent second look laparoscopy, 21 (95%) had no macroscopic evidence of recurrent endometrial carcinoma and repeat negative peritoneal cytology; 1 patient (5%) had persistent malignant peritoneal cytology but was NED at third look laparoscopy one year later. All 25 patients are off progesterone therapy and remain clinically NED from 12-64 months. Although progesterone therapy for malignant peritoneal cytology resulted in a 100% reversal of malignant peritoneal cytology to normal in the 22 patients who underwent second or third look laparoscopy and all 25 patients remain clinically NED, the true value of progesterone therapy can only be ascertained by a randomized trial of progesterone versus no therapy.

OBJECTIVE To evaluate the economic and clinical feasibility of introducing rigid endoscopy and laparoscopy to a small animal general practice. DESIGN Prospective study. SAMPLE A single 2-veterinarian small animal practice in southern California. PROCEDURES In early 2012, endoscopic equipment was purchased, and both veterinarians in the practice undertook training in rigid endoscopic and laparoscopic procedures. Subsequently, information for client-owned animals that underwent endoscopic and laparoscopic procedures during a 12-month period (2012 to 2013) was collected. Cost of equipment and training, revenue generated, specific procedures performed, surgery time, complications, and client satisfaction were evaluated. RESULTS 78 endoscopic procedures were performed in 73 patients, including 71 dogs, 1 cat, and 1 rabbit. Cost of endoscopic and laparoscopic equipment and training in the first year was $14,809.71; most equipment was financed through a 5-year lease at a total cost of $57,507.70 ($ 10,675.20/y). Total revenue generated in the first year was $50,423.63. The most common procedures performed were ovariectomy (OVE; n = 49), prophylactic gastropexy (6), and video otoscopy (12). Mean ± SD surgery times for OVE (n = 44) and for OVE with gastropexy (5) were 63.7 ± 19.7 minutes and 73.0 ± 33.5 minutes; respectively. Twelve of 54 patients undergoing laparoscopic procedures experienced minor intraoperative complications. Conversion to laparotomy was not required in any patient. There were no major complications. All 49 clients available for follow-up were satisfied. CONCLUSIONS AND CLINICAL RELEVANCE With appropriate training and equipment, incorporation of basic rigid endoscopy and laparoscopy may be feasible in small animal general practice. However, results of the present study are not applicable to all veterinarians and practice settings, and patient safety considerations should always be paramount.

Determining the optimal design for surgical skills training is an ongoing research endeavor. In education literature, varied practice is listed as a positive intervention to improve acquisition of knowledge and motor skills. In the current study we tested the effectiveness of a varied practice intervention during laparoscopy training. Twenty-four trainees (control group) without prior experience received a 3 weeks laparoscopic skills training utilizing four basic and one advanced training task. Twenty-eight trainees (experimental group) received the same training with a random training task schedule, more frequent task switching and inverted viewing conditions on the four basic training tasks, but not the advanced task. Results showed inferior performance of the experimental group on the four basic laparoscopy tasks during training, at the end of training and at a 2 months retention session. We assume the inverted viewing conditions have led to the deterioration of learning in the experimental group because no significant differences were found between groups on the only task that had not been practiced under inverted viewing conditions; the advanced laparoscopic task. Potential moderating effects of inter-task similarity, task complexity, and trainee characteristics are discussed.

To compare the diagnostic accuracy of ultrasonography (US), F18-fluorodeoxyglucose positron emission tomography/CT (PET/CT), contrast enhanced CT (CECT), serum anti-thyroid antibody for detecting Hashimoto's thyroiditis in thyroid cancer patients who underwent neck surgery. A total of 150 patients with suspicious for thyroid cancer, who had previously undergone US guided needle aspiration of thyroid, were evaluated with the use of US, PET/CT, CECT and serum anti-thyroid antibody. The four studies were performed within two months before neck surgery. Hashimoto's thyroiditis was confirmed by histopathological results. The diagnostic accuracy of US, PET/CT, CECT and serum anti-thyroid antibody were calculated statistically. Hashimoto's thyroiditis was diagnosed in 51 out of the 150 patients, following neck surgery. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of US were 76.5%, 92.9%, 84.8%, 88.5%, and 87.3%, respectively. The corresponding values of PET/CT were 37.3%, 96.0%, 82.6%, 74.8%, and 76.0%, and CECT were 62.7%, 89.9%, 76.2%, 82.4%, and 80.7%, and serum anti-thyroid antibody level were 90.2%, 93.9%, 88.5%, 94.9%, and 92.7%, respectively. McNemar test revealed significant difference among PET/CT and others, but no significant differences among US, CECT and serum anti-thyroid antibody. Overall, serum anti-thyroid antibody showed most accurate diagnostic performance. In detecting Hashimoto's thyroiditis, serum anti-thyroid antibody showed higher diagnostic accuracy than others. US also showed relatively high diagnostic accuracy.

Virtual reality (VR) applications with head-mounted displays (HMDs) have had an impact on information and multimedia technologies. The current work aimed to describe the process of developing a highly immersive VR simulation for laparoscopic surgery. We combined a VR laparoscopy simulator (LapSim) and a VR-HMD to create a user-friendly VR simulation scenario. Continuous clinical feedback was an essential aspect of the development process. We created an artificial VR (AVR) scenario by integrating the simulator video output with VR game components of figures and equipment in an operating room. We also created a highly immersive VR surrounding (IVR) by integrating the simulator video output with a [Formula: see text] video of a standard laparoscopy scenario in the department's operating room. Clinical feedback led to optimization of the visualization, synchronization, and resolution of the virtual operating rooms (in both the IVR and the AVR). Preliminary testing results revealed that individuals experienced a high degree of exhilaration and presence, with rare events of motion sickness. The technical performance showed no significant difference compared to that achieved with the standard LapSim. Our results provided a proof of concept for the technical feasibility of an custom highly immersive VR-HMD setup. Future technical research is needed to improve the visualization, immersion, and capability of interacting within the virtual scenario.

Virtual reality (VR) training simulators have started playing a vital role in enhancing surgical skills, such as hand-eye coordination in laparoscopy, and practicing surgical scenarios that cannot be easily created using physical models. We describe a new VR simulator for basic training in laparoscopy, i.e. SmartSIM, which has been developed using a generic open-source physics engine called the simulation open framework architecture (SOFA). This paper describes the systems perspective of SmartSIM including design details of both hardware and software components, while highlighting the critical design decisions. Some of the distinguishing features of SmartSIM include: (i) an easy-to-fabricate custom-built hardware interface; (ii) use of a generic physics engine to facilitate wider accessibility of our work and flexibility in terms of using various graphical modelling algorithms and their implementations; and (iii) an intelligent and smart evaluation mechanism that facilitates unsupervised and independent learning.

Initial staging of gastric cancer consists of computed tomography (CT) and gastroscopy. In locally advanced (cT3-4) gastric cancer, fluorodeoxyglucose positron emission tomography with CT (FDG-PET/CT or PET) and staging laparoscopy (SL) may have a role in staging, but evidence is scarce. The aim of this study is to evaluate the impact and cost-effectiveness of PET and SL in addition to initial staging in patients with locally advanced gastric cancer. This prospective observational cohort study will include all patients with a surgically resectable, advanced gastric adenocarcinoma (cT3-4b, N0-3, M0), that are scheduled for treatment with curative intent after initial staging with gastroscopy and CT. The modalities to be investigated in this study is the addition of PET and SL. The primary outcome of this study is the proportion of patients in whom the PET or SL lead to a change in treatment strategy. Secondary outcome parameters are: diagnostic performance, morbidity and mortality, quality of life, and cost-effectiveness of these additional diagnostic modalities. The study recently started in August 2017 with a duration of 36 months. At least 239 patients need to be included in this study to demonstrate that the diagnostic modalities are break-even. Based on the annual number of gastrectomies in the participating centers, it is estimated that approximately 543 patients are included in this study. In this study, it is hypothesized that performing PET and SL for locally advanced gastric adenocarcinomas results in a change of treatment strategy in 27% of patients and an annual cost-reduction in the Netherlands of €916.438 in this patient group by reducing futile treatment. The results of this study may be applicable to all countries with comparable treatment algorithms and health care systems. NCT03208621 . This trial was registered prospectively on June 30, 2017.

Virtual reality (VR) simulators for surgical training might possess the properties needed for basic training in laparoscopy. Evidence for training efficacy of VR has been investigated by research of varying quality over the past decade. To review randomized controlled trials regarding VR training efficacy compared with traditional or no training, with outcome measured as surgical performance in humans or animals. In June 2011 Medline, Embase, the Cochrane Central Register of Controlled Trials, Web of Science and Google Scholar were searched using the following medical subject headings (MeSh) terms: Laparoscopy/standards, Computing methodologies, Programmed instruction, Surgical procedures, Operative, and the following free text terms: Virtual real* OR simulat* AND Laparoscop* OR train* Controlled trials. All randomized controlled trials investigating the effect of VR training in laparoscopy, with outcome measured as surgical performance. A total of 98 studies were screened, 26 selected and 12 included, with a total of 241 participants. Operation time was reduced by 17-50% by VR training, depending on simulator type and training principles. Proficiency-based training appeared superior to training based on fixed time or fixed numbers of repetition. Simulators offering training for complete operative procedures came out as more efficient than simulators offering only basic skills training. Skills in laparoscopic surgery can be increased by proficiency-based procedural VR simulator training. There is substantial evidence (grade IA - IIB) to support the use of VR simulators in laparoscopic training. © 2012 The Authors  Acta Obstetricia et Gynecologica Scandinavica© 2012 Nordic Federation of Societies of Obstetrics and Gynecology.

This study was undertaken to determine the quality of information on the Internet regarding laparoscopy. Four popular World Wide Web search engines were used with the key word "laparoscopy." Advertisements, patient- or physician-directed information, and controversial material were noted. A total of 14,030 Web pages were found, but only 104 were unique Web sites. The majority of the sites were duplicate pages, subpages within a main Web page, or dead links. Twenty-eight of the 104 pages had a medical product for sale, 26 were patient-directed, 23 were written by a physician or group of physicians, and six represented corporations. The remaining 21 were "miscellaneous." The 46 pages containing educational material were critically reviewed. At least one of the senior authors found that 32 of the pages contained controversial or misleading statements. All of the three senior authors (LKN, NAO, GAF) independently agreed that 17 of the 46 pages contained controversial information. The World Wide Web is not a reliable source for patient or physician information about laparoscopy. Authenticating medical information on the World Wide Web is a difficult task, and no government or surgical society has taken the lead in regulating what is presented as fact on the World Wide Web.

To determine the feasibility of esophagogastric anastomosis in esophageal cancer radical resection under thoracoscopy combined with laparoscopy in terms of complications and operation time. Experimental study. Department of Thoracic Surgery, Affiliated with The First Hospital, Suzhou University, from June 2008 to June 2012. Clinical data of 136 patients operated for esophageal cancer by radical resection under thoracoscopy combined with laparoscopy was analyzed. Eighty one superior and middle segment esophageal carcinoma patients were operated through right thoracoscope, abdominoscope, and neck incision. The esophagogastric anastomosis was completed in the left side of neck by handiwork. Fifty five inferior segment esophageal carcinoma were operated through right thoracoscope, abdominoscope and the esophagogastric anastomosis was completed with stapler in right thoracic cavity through superior belly incision and diaphragmatic hiatus. The operation time and the intra-operative blood loss in patients with intrathoracic mechanical anastomosis was significantly lower than that of cervical anastomosis. Other variables were not significantly different. The practicability of this method of anastomosis that completed with stapler in right thoracic cavity through superior belly incision and diaphragmatic hiatus had been well confirmed.

Full Text Available Erica Schipper,1 Camran Nezhat21Center for Minimally Invasive and Robotic Surgery, Palo Alto, CA; 2Obstetrics/Gynecology and Surgery, Stanford University Medical Center, Palo Alto, CA, USAAbstract: Endometriosis is a highly enigmatic disease with multiple presentations ranging from infertility to severe pain, often causing significant morbidity. Video-assisted laparoscopy (VALS has now replaced laparotomy as the gold standard for the diagnosis and management of endometriosis. While imaging has a role in the evaluation of some patients, histologic examination is needed for a definitive diagnosis. Laboratory evaluation currently has a minor role in the diagnosis of endometriosis, although studies are underway investigating serum markers, genetic studies, and endometrial sampling. A high index of suspicion is essential to accurately diagnose this complex condition, and a multidisciplinary approach is often indicated. The following review discusses laparoscopic diagnosis of endometriosis from the pre-operative evaluation of patients suspected of having endometriosis to surgical technique for safe and adequate laparoscopic diagnosis of the condition and postsurgical care.Keywords: endometriosis, video-assisted, laparoscopy, diagnosis

3D straight-stick laparoscopy versus 3D robotics for task performance in novice surgeons: a randomised crossover trial.

Science.gov (United States)

Shakir, Fevzi; Jan, Haider; Kent, Andrew

2016-12-01

The advent of three-dimensional passive stereoscopic imaging has led to the development of 3D laparoscopy. In simulation tasks, a reduction in error rate and performance time is seen with 3D compared to two-dimensional (2D) laparoscopy with both novice and expert surgeons. Robotics utilises 3D and instrument articulation through a console interface. Robotic trials have demonstrated that tasks performed in 3D produced fewer errors and quicker performance times compared with those in 2D. It was therefore perceived that the main advantage of robotic surgery was in fact 3D. Our aim was to compare 3D straight-stick laparoscopic task performance (3D) with robotic 3D (Robot), to determine whether robotic surgery confers additional benefit over and above 3D visualisation. We randomised 20 novice surgeons to perform four validated surgical tasks, either with straight-stick 3D laparoscopy followed by 3D robotic surgery or in the reverse order. The trial was conducted in two fully functional operating theatres. The primary outcome of the study was the error rate as defined for each task, and the secondary outcome was the time taken to complete each task. The participants were asked to perform the tasks as quickly and as accurately as possible. Data were analysed using SPSS version 21. The median error rate for completion of all four tasks with the robot was 2.75 and 5.25 for 3D with a P value performance time for completion of all four tasks with the robot was 157.1 and 342.5 s for 3D with a P value 3D robotic systems over 3D straight-stick laparoscopy, in terms of reduced error rate and quicker task performance time.

The ability of physicians to identify a patent processus vaginalis by laparoscopic examination of the internal ring is now well established, but the efficacy on patient outcome is not. The authors reviewed their experience to determine the effect of diagnostic laparoscopy of the internal ring on the management of children with inguinal hernias. The records of 150 children who underwent inguinal surgery were reviewed--75 before (group 1) and 75 after (group 2) pediatric laparoscopy was introduced into the authors' practice. The children in group 1 were selected for unilateral or bilateral surgery based on history, age, sex, side of presentation, and parental preference. For group 2, laparoscopy was an additional option offered to appropriate patients. Laparoscopy was performed in 43 group 2 patients, using an infraumbilical site. The minimum follow-up period was 2 years for group 1 and 1 year for group 2. The mean ages for groups 1 and 2 were 41.2 and 39.7 months, respectively. There were 61 boys and 14 girls in each group. The percentages of right (R), left (L), and bilateral (B) findings, based on clinical observation, were 56.0 (R), 29.3 (L), and 14.7 (B) for group 1, and 58.7 (R), 26.6 (L), and 14.7 (B) for group 2. The incidence of bilateral surgical exploration was similar for the two groups (group 1, 58.6%; group 2, 61.3%). The addition of laparoscopy significantly lowered the incidence of negative explorations (group 1, 16.0%; group 2, 2.6%; P < .01).(ABSTRACT TRUNCATED AT 250 WORDS)

1980-01-01

Laparoscopy andor laparotomy had been performed in 91 patients also examined by hysterosalpingography (HSG) during two years. The comparison of the radiological and the operative findings shows, that total occlusion and hydrosalpinx are radiological signs of adhesions in the pelvis. A depot of contrast medium remaining around the fimbriated end of the oviduct is also a sign of adhesions. More than half of the patients with adhesions surrounding the oviducts and/or endometriosis had however normal hysterosalpingograms. Thus, the radiological examination, hysterosalpingography, has a low sensitivity rate concerning pelvic abnormalities. (orig.) [de

Laparoscopy-assisted distal gastrectomy for early gastric cancer has gained acceptance and popularity worldwide. However, laparoscopy-assisted distal gastrectomy for advanced gastric cancer is still controversial. Therefore, we propose this prospective randomized controlled multi-center trial in order to evaluate the safety and feasibility of laparoscopy assisted D2-gastrectomy for advanced stage gastric cancer. Patients undergoing distal gastrectomy for advanced gastric cancer staged cT2/3/4 cN0/1/2/3a cM0 by endoscopy and computed tomography are eligible for enrollment after giving their informed consent. Patients will be randomized either to laparoscopy-assisted distal gastrectomy or open distal gastrectomy. Sample size calculation revealed that 102 patients are to be included per treatment arm. The primary endpoint is the non-compliance rate of D2 dissection; relevant secondary endpoints are three-year disease free survival, surgical and postoperative complications, hospital stay and unanimity rate of D2 dissection evaluated by reviewing the intraoperative video documentation. Oncologic safety is the major concern regarding laparoscopy-assisted distal gastrectomy for advanced gastric cancer. Therefore, the non-compliance rate of clearing the N2 area was chosen as the most important parameter for the technical feasibility of the laparoscopic procedure. Furthermore, surgical quality will be carefully reviewed, that is, three independent experts will review the video records and score with a check list. For a long-term result, disease free survival is considered a secondary endpoint for this trial. This study will offer promising evidence of the feasibility and safety of Laparoscopy-assisted distal gastrectomy for advanced gastric cancer. NCT01088204 (international), NCCCTS-09-448 (Korea).

Meckel’s diverticulum (MD) is estimated to affect 1%-2% of the general population, and it represents a clinically silent finding of a congenital anomaly in up to 85% of the cases. In adults, MD may cause symptoms, such as overt occult lower gastrointestinal bleeding. The diagnostic imaging workup includes computed tomography scan, magnetic resonance imaging enterography, technetium 99m scintigraphy (99mTc) using either labeled red blood cells or pertechnetate (known as the Meckel’s scan) and angiography. The preoperative detection rate of MD in adults is low, and many patients ultimately undergo exploratory laparoscopy. More recently, however, endoscopic identification of MD has been possible with the use of balloon-assisted enteroscopy via direct luminal access, which also provides visualization of the diverticular ostium. The aim of this study was to review the diagnosis by double-balloon enteroscopy of 4 adults with symptomatic MD but who had negative diagnostic imaging workups. These cases indicate that balloon-assisted enteroscopy is a valuable diagnostic method and should be considered in adult patients who have suspected MD and indefinite findings on diagnostic imaging workup, including negative Meckel’s scan.

2006-03-01

Full Text Available Abstract Background Laparoscopy has became as the preferred surgical approach to a number of different diseases because it allows a correct diagnosis and treatment at the same time. In abdominal emergencies, both components of treatment – exploration to identify the causative pathology and performance of an appropriate operation – can often be accomplished via laparoscopy. There is still a debate of peritonitis as a contraindication to this kind of approach. Aim of the present work is to illustrate retrospectively the results of a case-control experience of laparoscopic vs. open surgery for abdominal peritonitis emergencies carried out at our institution. Methods From January 1992 and January 2002 a total of 935 patients (mean age 42.3 ± 17.2 years underwent emergent and/or urgent surgery. Among them, 602 (64.3% were operated on laparoscopically (of whom 112 -18.7% – with peritonitis, according to the presence of a surgical team trained in laparoscopy. Patients with a history of malignancy, more than two previous major abdominal surgeries or massive bowel distension were not treated Laparoscopically. Peritonitis was not considered contraindication to Laparoscopy. Results The conversion rate was 23.2% in patients with peritonitis and was mainly due to the presence of dense intra-abdominal adhesions. Major complications ranged as high as 5.3% with a postoperative mortality of 1.7%. A definitive diagnosis was accomplished in 85.7% (96 pat. of cases, and 90.6% (87 of these patients were treated successfully by Laparoscopy. Conclusion Even if limited by its retrospective feature, the present experience let us to consider the Laparoscopic approach to abdominal peritonitis emergencies a safe and effective as conventional surgery, with a higher diagnostic yield and allows for lesser trauma and a more rapid postoperative recovery. Such features make Laparoscopy a challenging alternative to open surgery in the management algorithm for abdominal

Input and output for surgical simulation: devices to measure tissue properties in vivo and a haptic interface for laparoscopy simulators.

Current efforts in surgical simulation very often focus on creating realistic graphical feedback, but neglect some or all tactile and force (haptic) feedback that a surgeon would normally receive. Simulations that do include haptic feedback do not typically use real tissue compliance properties, favoring estimates and user feedback to determine realism. When tissue compliance data are used, there are virtually no in vivo property measurements to draw upon. Together with the Center for Innovative Minimally Invasive Therapy at the Massachusetts General Hospital, the Haptics Group is developing tools to introduce more comprehensive haptic feedback in laparoscopy simulators and to provide biological tissue material property data for our software simulation. The platform for providing haptic feedback is a PHANToM Haptic Interface, produced by SensAble Technologies, Inc. Our devices supplement the PHANToM to provide for grasping and optionally, for the roll axis of the tool. Together with feedback from the PHANToM, which provides the pitch, yaw and thrust axes of a typical laparoscopy tool, we can recreate all of the haptic sensations experienced during laparoscopy. The devices integrate real laparoscopy toolhandles and a compliant torso model to complete the set of visual and tactile sensations. Biological tissues are known to exhibit non-linear mechanical properties, and change their properties dramatically when removed from a living organism. To measure the properties in vivo, two devices are being developed. The first is a small displacement, 1-D indenter. It will measure the linear tissue compliance (stiffness and damping) over a wide range of frequencies. These data will be used as inputs to a finite element or other model. The second device will be able to deflect tissues in 3-D over a larger range, so that the non-linearities due to changes in the tissue geometry will be measured. This will allow us to validate the performance of the model on large tissue

Pancreatic ductal obstruction leading to ductal dilation and recurrent pancreatitis is uncommon in children. Treatment is dependent upon etiology but consists of decompression of the pancreatic duct (PD) proximally, if possible, by endoscopic retrograde cholangiopancreatography (ERCP) intervention or surgical decompression with pancreaticojejunal anastomosis. After institutional review board approval, we retrospectively reviewed the records for 2 children who underwent lateral pancreaticojejunostomy for pancreatic ductal dilation. Data, including demographics, diagnostic studies, operative details, complications, outcomes, and follow-up, were analyzed. Case 1 was a 4-year-old female with pancreatic ductal obstruction with multiple episodes of recurrent pancreatitis and failure of ERCP to clear her PD of stones. She underwent a laparoscopic cholecystectomy with a lateral pancreaticojejunostomy (Puestow procedure). She recovered well with no further episodes of pancreatitis and normal pancreatic function 4 years later. Case 2 was a 2-year-old female who developed recurrent pancreatitis and was found to have papillary stenosis and long common bile-PD channel. Despite multiple sphincterotomies, laparoscopic cholecystectomy, and laparoscopic hepaticoduodenostomy, she continued to experience episodes of pancreatitis. She underwent a laparoscopy converted to open lateral pancreaticojejunostomy. Her recovery was also smooth having had no episodes of pancreatitis or hospital admissions for over 2 years following the Puestow. Indication for lateral pancreaticojejunostomy or Puestow procedure is rare in children and even less often performed using laparoscopy. In our small experience, both patients with pancreatic ductal obstruction managed with Puestow's procedure enjoy durable symptom and pain relief in the long term.

Objective: To evaluate the utility of multiplanar reconstruction (MPR) image for CT-guided biopsy and determine factors of influencing diagnostic accuracy and the pneumothorax rate. Materials and methods: 390 patients with 396 pulmonary nodules underwent transthoracic CT-guided aspiration biopsy (TNAB) and transthoracic CT-guided cutting needle core biopsy (TCNB) as follows: 250 solitary pulmonary nodules (SPNs) underwent conventional CT-guided biopsy (conventional method), 81 underwent CT-fluoroscopic biopsy (CT-fluoroscopic method) and 65 underwent conventional CT-guided biopsy in combination with MPR image (MPR method). Success rate, overall diagnostic accuracy, pneumothorax rate and total procedure time were compared in each method. Factors affecting diagnostic accuracy and pneumothorax rate of CT-guided biopsy were statistically evaluated. Results: Success rates (TNAB: 100.0%, TCNB: 100.0%) and overall diagnostic accuracies (TNAB: 96.9%, TCNB: 97.0%) of MPR were significantly higher than those using the conventional method (TNAB: 87.6 and 82.4%, TCNB: 86.3 and 81.3%) (P<0.05). Diagnostic accuracy were influenced by biopsy method, lesion size, and needle path length (P<0.05). Pneumothorax rate was influenced by pathological diagnostic method, lesion size, number of punctures and FEV1.0% (P<0.05). Conclusion: The use of MPR for CT-guided lung biopsy is useful for improving diagnostic accuracy with no significant increase in pneumothorax rate or total procedure time

Laparoscopy in the management of pediatric vesicoureteral reflux

Directory of Open Access Journals (Sweden)

Atul A Thakre

2007-01-01

Full Text Available The prevalence of vesicoureteral reflux (VUR has been estimated as. 4 to 1.8% among the pediatric population. In children with urinary tract infection the prevalence is typically from 30-50% with higher incidence occurring in infancy. When correction of VUR is determined to be necessary, traditionally open ureteral reimplantation by a variety of techniques has been the mainstay of treatment. This approach is justified because surgical correction affords a very high success rate of 99% in experienced hands and a low complication rate. In that context the purpose of this review article is to highlight the use of laparoscopy and robot-assisted techniques to perform ureteric reimplantation for the management of pediatric VUR. A detailed review of recent literature on the subject is performed to find out various aspects of minimally invasive surgery in the treatment of VUR, highlighting evolution of management approaches, operative steps, complications, results and the current status in clinical practice. We also share our experience on the subject.

To use office gel sonovaginography (SVG) to predict posterior deep infiltrating endometriosis (DIE) in women undergoing laparoscopy. This was a multicenter prospective observational study carried out between January 2009 and February 2013. All women were of reproductive age, had a history of chronic pelvic pain and underwent office gel SVG assessment for the prediction of posterior compartment DIE prior to laparoscopic endometriosis surgery. Gel SVG findings were compared with laparoscopic findings to determine the diagnostic accuracy of office gel SVG for the prediction of posterior compartment DIE. In total, 189 women underwent preoperative gel SVG and laparoscopy for endometriosis. At laparoscopy, 57 (30%) women had posterior DIE and 43 (23%) had rectosigmoid/anterior rectal DIE. For the prediction of rectosigmoid/anterior rectal (i.e. bowel) DIE, gel SVG had an accuracy of 92%, sensitivity of 88%, specificity of 93%, positive predictive value (PPV) of 79%, negative predictive value (NPV) of 97%, positive likelihood ratio (LR+) of 12.9 and negative likelihood ratio (LR-) of 0.12 (P = 3.98E-25); for posterior vaginal wall and rectovaginal septum (RVS) DIE, respectively, the accuracy was 95% and 95%, sensitivity was 18% and 18%, specificity was 99% and 100%, PPV was 67% and 100%, NPV was 95% and 95%, LR+ was 32.4 and infinity and LR- was 0.82 and 0.82 (P = 0.009 and P = 0.003). Office gel SVG appears to be an effective outpatient imaging technique for the prediction of bowel DIE, with a higher accuracy for the prediction of rectosigmoid compared with anterior rectal DIE. Although the sensitivity for vaginal and RVS DIE was limited, gel SVG had a high specificity and NPV for all forms of posterior DIE, indicating that a negative gel SVG examination is highly suggestive of the absence of DIE at laparoscopy.

To evaluate the chance of adhesion formation after laparoscopic salpingo-ovariolysis and determine the efficacy of early second-look laparoscopy (SLL). Prospective, randomized study (Canadian Task Force classification I). Shiraz University hospitals. Ninety women with mean duration of infertility of 7.2 years. Operative laparoscopy, with early SLL with adhesiolysis in 46 (group 1) and no SLL in 44 women (group 2). Adnexal adhesions were evaluated according to American Society for Reproductive Medicine adhesion classification. Separation of newly reformed adhesions was performed at the time of SLL. Patients were followed for a year after operation without other infertility treatment. At the time of operation in group 1, adnexal adhesions were graded as severe (class D) in 19 women, moderate (class C) in 31, mild (class B) in 28, and minimal (class A) in 14. Respective figures in group 2 were 10, 30, 34, and 14. After salpingo-ovariolysis these figures were 12, 10, 20, and 50 in group 1 and 6, 14, 17, and 51 in group 2. In group 1 in whom early second-look laparoscopy was performed, at the start of the operation these figures were 17, 20, 21, and 34, and after operation 12, 8, 20, and 52, respectively. There were 11 term pregnancies in group 1 and 15 in group 2. No women with severe adhesions in either group conceived. In group 1, chances of term pregnancy were 18.75% for those with moderate adhesions, 35.71% for women with mild adhesions, and 42.86% in patients with minimal adhesions. Respective figures in group 2 were 26.67%, 41.18%, and 57.14%. The chance of moderate and severe adhesion reformation after laparoscopic salpingo-ovariolysis was 40.2%. Although separation of these adhesions could be performed more easily at the time of early SLL, the chance of pregnancy did not increase compared with that in patients who did not undergo SLL.

Laparoscopy for abdominal surgical emergencies is gaining increasing acceptance given the spreading of advanced laparoscopic skills among modern surgeons, as it may allow at the same time an accurate diagnosis and appropriate treatment of acute abdomen. The use of the laparoscopic approach also in case of diffuse peritonitis is now becoming accepted provided hemodynamic stability, despite the common belief in the past decades that such severe condition represented an indication for conversion to open surgery or an immediate contraindication to continue laparoscopy. Crohn's Disease (CD) is a rare cause of acute abdomen and peritonitis, only a few cases of CD acute perforations are reported in the published literature; these cases have always been approached and treated by open laparotomy. We report on a case of a faecal peritonitis due to an acute perforation caused by a terminal ileitis in an undiagnosed CD. The patient underwent diagnostic laparoscopy followed by a laparoscopic ileo-colic resection and primary intracorporeal anastomosis, with a successful postoperative outcome. Complicated CD has to be considered within the possible causes of small bowel non-traumatic perforation. Emergency laparoscopy with resection and primary intra-corporeal anastomosis can be feasible and may be a safe and effective minimally invasive alternative to open surgery even in case of faecal peritonitis, in selected stable patients and in presence of appropriate laparoscopic colorectal surgical skills and experience. To the best of our knowledge the present experience is the first ever reported case managed with a totally laparoscopic extended ileocecal resection with intracorporeal anastomosis in case of acutely perforated CD and diffuse peritonitis.

An increasing amount of attention has been paid to minimally invasive function-preserving gastrectomy, with an increase in incidence of early gastric cancer in the upper stomach. This study aimed to compare oncological outcomes, surgical stress, and nutritional status between robot-assisted proximal gastrectomy (RAPG) and laparoscopy-assisted proximal gastrectomy (LAPG). Eighty-nine patients were enrolled in this retrospective study between November 2011 and December 2013. Among them, 27 patients underwent RAPG and 62 underwent LAPG. Perioperative parameters, surgical stress, nutritional status, disease-free survival, and overall survival were compared between the 2 groups. Sex, age, and comorbidity were similar in the RAPG and LAPG groups. There were also similar perioperative outcomes regarding operation time, complications, and length of hospital stay between the groups. The reflux esophagitis rates following RAPG and LAPG were 18.5% and 14.5%, respectively ( P = .842). However, patients in the RAPG group had less blood loss ( P = .024), more harvested lymph nodes ( P = .021), and higher costs than those in the LAPG group ( P .05). There appeared to be higher hemoglobin levels at 6 months ( P = .053) and a higher body mass index at 12 months ( P = .056) postoperatively in patients in the RAPG group compared with those in the LAPG group, but this difference was not significant. Similar disease-free survival and overall survival rates were observed between the groups. RAPG could be an alternative to LAPG for patients with early gastric cancer in the upper stomach with comparable oncological safety and nutritional status. Further well-designed, prospective, large-scale studies are needed to validate these results.

Secondary abdominal appendicular pregnancy: Case report

Directory of Open Access Journals (Sweden)

Rosso Mićo

2014-01-01

Full Text Available Introduction. The case report describes a 29-year-old nulliparous woman that was admitted at the Department of Gynecology and Obstetrics of the Clinical Hospital Osijek complaining of mild abdominal pain without vaginal discharge. Case Outline. The patient’s menstrual cycle was irregular, from 30-45 days. An ultrasound examination showed suspicion of an ectopic pregnancy with a βHCG level of 1358 IU/L. Due to the presence of liquid in the pouch of Douglas the patient underwent emergency laparoscopy, which showed the presence of tumor mass between the right Fallopian tube and the appendix. These two structures associated with adhesions corresponded to secondary implantation after spontaneous tubal abortion which was confirmed by histopathologic analysis. Conclusion. Laparoscopy has emerged as the “gold standard” in the diagnosis and treatment of ectopic pregnancy, in this case the secondary abdominal pregnancy. From the diagnostic point of view, all women of reproductive age should be considered pregnant until proven otherwise, also keeping in mind that ectopic pregnancies can have different locations and many clinical features.

Diagnostic laparoscopy (DL) has decreased the rate of nontherapeutic laparotomy for patients suffering from penetrating injuries. We evaluated whether DL similarly lowers the rate of nontherapeutic laparotomy for patients with blunt injuries. All patients undergoing DL over a 10-year period (ie, 2001-2010) in a single level 1 trauma center were classified by the mechanism of injury. Demographic and perioperative data were compared using the Student t and Fisher exact tests. There were 131 patients included, 22 of whom sustained blunt injuries. Patients suffering from blunt injuries were more severely injured (Injury Severity Score 18.0 vs 7.3, P = .0001). The most common indication for DL after blunt injury was a computed tomographic scan concerning for bowel injury (59.1%). The rate of nontherapeutic laparotomy for patients sustaining penetrating vs blunt injury was 1.8% and nil, respectively. DL, when coupled with computed tomographic findings, is an effective tool for the initial management of patients with blunt injuries. Copyright © 2013 Elsevier Inc. All rights reserved.

To investigate and compare inter-observer variability and diagnostic performance of thyroid ultrasound (US) between a faculty member and observing residents. From October 2007 to June 2009, 18 residents underwent training in thyroid US section. Group 1 included 8 residents that were trained for the first time and group 2 included 10 residents that were trained for the second time. US features of nodules were recorded according to the composition, echogenicity, margin, calcifications, shape, and final assessment by a faculty member and residents, respectively. Following a discussion, a faculty member performed fine needle aspiration. Then, the inter-observer variability and diagnostic performance between a faculty member and residents were investigated and compared for US. In group 1, agreement for composition in resident 1, calcification for residents 5 and 6, and shape for resident 4 were slight, moderate, moderate, and moderate, respectively. In group 2, agreement for composition in residents 1 and 10 were moderate. Substantial or greater agreement was observed more frequently in group 2 than 1. The diagnostic performances for both the faculty and residents were high and not statistically different. Agreement for US features between a faculty and residents as well as diagnostic performance were high. Moreover, diagnostic performance of residents that underwent training a second time of training was higher than residents that underwent training only once

Is there any occurrence of hidden (occult) endometriotic lesions in normal peritoneum of women with and without visible endometriosis? We detected a slightly higher occurrence of occult microscopic endometriosis (OME) in normal peritoneum of women with visible endometriosis than in control women. Based on a small number of cases, the concept of invisible microscopic endometriosis in visually normal peritoneum has been reported for more than a decade but there is controversy regarding their tissue activity and clinical significance. This case-controlled research study was conducted with prospectively collected normal peritoneal samples from 151 women with and 62 women without visible endometriosis. Normal peritoneal biopsy specimens from different pelvic sites of were collected during laparoscopy. A histological search of all peritoneal biopsy specimens for the detection of invisible endometriosis was done by immunoreaction to Ber-EP4 (epithelial cell marker), CD10 (stromal cell marker) and Calretinin (mesothelial cell marker). Tissue expression of estrogen/progesterone receptors (ER/PR) and cell proliferation marker, Ki-67, was performed by immunohistochemistry to identify tissue activity. Three different patterns of OME were detected based on (I) the presence of typical gland/stroma, (II) reactive hyperplastic change of endometrioid epithelial cells with surrounding stroma and (III) single-layered epithelium-lined cystic lesions with surrounding stroma. A higher tendency toward the occurrence of OME was found in women with visible endometriosis (15.2%, 23/151) compared with control women (6.4%, 4/62) (P = 0.06, χ(2) test). The epithelial cells and/or stromal cells of OME lesions were immunoreactive to Ber-EP4 and CD10 but not reactive to Calretinin. ER and PR expression was observed in all patterns of OME lesions. Ki-67 index was significantly higher in pattern I/II OME lesions than in pattern III OME lesions (Pendometriosis due to the presence of adhesions in

Sills, E Scott; Palermo, Gianpiero D

2016-07-01

We describe the successful removal of a pelvic contraceptive coil in a symptomatic 46-year-old patient who had Essure devices for four years, using a combined hysteroscopy-laparoscopy-fluoroscopy approach. Following normal hysteroscopy, at laparoscopy the right Essure implant was disrupted and its outer nitinol coil had perforated the fallopian tube. However, the inner rod (containing polyethylene terephthalate) had migrated to an extrapelvic location, near the proximal colon. In contrast, the left implant was situated within the corresponding tube. Intraoperative fluoroscopy was used to confirm complete removal of the device, which was further verified by postoperative computed tomography. The patient's condition improved after surgery and she continues to do well. This is the first report to describe this technique in managing Essure complications remote from time of insertion. Our case highlights the value and limitations of preoperative and intraoperative imaging to map Essure fragment location before surgery.

2011-01-01

Laparoscopy and dye test is an important investigation in the evaluation of infertile women which has been underutilised in our practice. This review is aimed at determining whether the findings of this procedure are substantial enough to make it a first line evaluation for infertile women. A review of the laparoscopic findings in infertile women who presented for evaluation and treatment at a private fertility centre was carried out. A total of 253 day-case laparoscopy and dye test procedures were reviewed, 115 (45.0%) were done for primary infertility, 137 (54.5%) for secondary infertility and 1 (0.4%) for primary amenorrhoea and infertility. The mean period of infertility was 4.5 years with a range of 2-10 years and the women were aged between 19 and 52 years. Analysis of the result showed that 100 (39.5%) women had normal patent tubes while 153 (60.4%) had tubal pathologies like bilateral tubal occlusion in 97 (38.3%) and unilateral tubal occlusion in 56 (22.1%) women. Pelvic adhesion of varying degrees of severity was present in 108 (42.7%) women. Bilateral tubal occlusion was more common in nulliparous women and those aged between 30-39 years. One or both ovaries were normal (functional) in 189 (74.7%) women. Altogether, only 43 (17.0%) women were "normal" (had patent tubes, functional ovary and no pelvic adhesion). Additional pelvic pathology was present in 142 (56.1%) women. The commonest was uterine fibroid (leiomyomata) of various sizes in 100 (39.5%) of the women, followed by ovarian cyst in 56 (22.2%) and endometriosis in 11 (4.4%) women. Other pathologies observed include uterine abnormalities and unruptured ectopic pregnancy. Only 16 (37.2%) of the 43 "normal" women had no additional pelvic pathology. The high prevalence o tuboperitoneal factor and additional pelvic pathology in these infertile women reveal the importance of laparoscopic evaluation. We recommend the use of laparoscopy and dye test as a first line investigation in our environment to

The aim of the present study was to evaluate the possible differences between total laparoscopy and laparotomy regarding their impact on postoperative quality of life and sexuality in disease-free cervical cancer survivors who received radical hysterectomy (RH) and/or lymphadenectomy alone and were followed for >1 year.We reviewed all patients with cervical cancer who had received surgical treatment in our hospital between January 2001 and March 2014. Consecutive sexually active survivors who received RH and/or lymphadenectomy for early stage cervical cancer were enrolled and divided into 2 groups based on surgical approach. Survivors were interviewed and completed validated questionnaires, including the European Organization for Research Treatment of Cancer Quality-of-Life Core Questionnaire including 30 items, the Cervical Cancer-Specific Module of European Organization for Research Treatment of Cancer Quality-of-Life Questionnaire including 24 items (EORTC QLQ-CX24), and the Female Sexual Function Index (FSFI).In total, 273 patients with histologically confirmed cervical cancer were retrospectively reviewed. However, only 64 patients had received RH and/or lymphadenectomy alone; 58 survivors meeting the inclusion criteria were enrolled, including 42 total laparoscopy cases and 16 laparotomy cases, with an average follow-up of 46.1 and 51.2 months, respectively. The survivors in the 2 groups obtained good and similar scores on all items of the European Organization for Research Treatment of Cancer Quality-of-Life Core Questionnaire including 30 items and Cervical Cancer-Specific Module of European Organization for Research Treatment of Cancer Quality-of-Life Questionnaire including 24 items, without significant differences after controlling for covariate background characteristics. To the date of submission, 21.4% (9/42) of cases in the total laparoscopy group and 31.2% (5/16) of cases in the laparotomy group had not resumed sexual behavior after RH. Additionally

Sezeur, Alain; Partensky, Christian; Chipponi, Jacques; Duron, Jean-Jacques

2008-08-01

We report the death of a young man during a laparoscopic partial splenectomy performed with an argon plasma coagulator to remove a benign cyst. The report analyzes the very particular mechanism of a gas embolism, which caused death here. This analysis leads us to recommend a close attention on the use of argon coagulators during laparoscopy. The aim of this article is to draw surgeons' attention to the conclusions of a court-ordered expert assessment intended to elucidate the mechanisms responsible for the death of a 20-year-old man during a laparoscopic partial splenectomy performed with an argon plasma coagulator to remove a benign cyst.

The Society of Gynecologic Surgeons Systematic Review Group performed a systematic review of both randomized and observational studies to compare robotic vs nonrobotic surgical approaches (laparoscopic, abdominal, and vaginal) for treatment of both benign and malignant gynecologic indications to compare surgical and patient-centered outcomes, costs, and adverse events associated with the various surgical approaches. MEDLINE and the Cochrane Central Register of Controlled Trials were searched from inception to May 15, 2012, for English-language studies with terms related to robotic surgery and gynecology. Studies of any design that included at least 30 women who had undergone robotic-assisted laparoscopic gynecologic surgery were included for review. The literature yielded 1213 citations, of which 97 full-text articles were reviewed. Forty-four studies (30 comparative and 14 noncomparative) met eligibility criteria. Study data were extracted into structured electronic forms and reconciled by a second, independent reviewer. Our analysis revealed that, compared with open surgery, robotic surgery consistently confers shorter hospital stay. The proficiency plateau seems to be lower for robotic surgery than for conventional laparoscopy. Of the various gynecologic applications, there seems to be evidence that renders robotic techniques advantageous over traditional open surgery for management of endometrial cancer. However, insofar as superiority, conflicting data are obtained when comparing robotics vs laparoscopic techniques. Therefore, the specific method of minimally invasive surgery, whether conventional laparoscopy or robotic surgery, should be tailored to patient selection, surgeon ability, and equipment availability.

Five patient with a hysterosalpingographic diagnosis of unicornuate uterus underwent resonance imaging (MRI) and subsequently laparoscopy/laparotomy to evaluate the ability of MRI to identify the various subclasses of this malformation. The method was demonstrated to be valid, since in all 5 cases (one subclass A1b, two subclass B) were correctly diagnosed. Compared with laparoscopy, MRI is less expensive, less invasive, and can be performed in women in whom laparoscopic examination is risky. However, unlike laparoscopy, MRI can not detect the presence of minimal and mild endometriosis and does not allow assessment of the tubal conditions. (au).

2004-09-01

Purpose: To determine the value of magnetic resonance imaging (MRI) of the pelvis in the preoperative diagnosis of endometriosis. Materials and Methods: Over a period of 8 months, preoperative MRI of the pelvis were obtained in 13 patients with suspected endometriosis (mean patient age 34.6 years; range 25-47 years). Results: In 9 of 13 patients (69%), the diagnosis of endometriosis was made by MRI and confirmed by laparoscopy in 8 cases. In 2 of 13 patients, endometriotic lesions were detectable by laparoscopy only. In the remaining 2 patients, no endometriosis was visible on MRI or by laparoscopy. MRI was able to visualize a total of 19 endometriotic lesions, with 14 (74%) confirmed by histopathologic examination following laparoscopy. Five of these 19 lesions (26%) visible on MRI were not seen by laparoscopy. Using laparoscopy and subsequent histopathologic examination, 27 endometriotic lesions were diagnosed, with 13 (48%) not seen on the preoperative MRI. Conclusion: MRI and laparoscopy are complementary diagnostic tools that will best document the full extent of endometriosis when combined. MRI can visualize additional lesions inaccessible to laparoscopy. Thus, MRI of the pelvis should used preoperatively for surgical treatment planning. (orig.)

2011-09-01

Full Text Available Abstract Situs inversus totalis (SIT is not itself a premalignant condition, however, rare synchronous or metachronous multiple primary malignancies have been reported. Herein we present a case of synchronous transverse and sigmoid colon cancers and a case of metachronous rectosigmoid colon and gastric cancers in patients with SIT. A 66-year-old male with SIT was referred for a two-month history of hematochezia. Synchronous colonic tumors were found on the proximal transverse and sigmoid colon. The patient underwent open total colectomy and was discharged without incident. A 71-year-old female with rectosigmoid colon cancer and SIT underwent laparoscopy-assisted low anterior resection. Fourteen months after the surgery, the patient developed a single hepatic metastasis and underwent hepatic segmentectomy (S6. Forty-six months after laparoscopy-assisted low anterior resection, the patient developed metachronous early gastric cancer on the antrum and underwent radical subtotal gastrectomy with gastroduodenostomy. The patient is doing well without recurrence for 28 months.

A realistic simulator for transabdominal preperitoneal (TAPP) inguinal hernia repair would enhance surgeons' training experience before they enter the operating theater. The purpose of this study was to create a novel physical simulator for TAPP inguinal hernia repair and obtain surgeons' opinions regarding its efficacy. Our novel TAPP inguinal hernia repair simulator consists of a physical laparoscopy simulator and a handmade organ replica model. The physical laparoscopy simulator was created by three-dimensional (3D) printing technology, and it represents the trunk of the human body and the bendability of the abdominal wall under pneumoperitoneal pressure. The organ replica model was manually created by assembling materials. The TAPP inguinal hernia repair simulator allows for the performance of all procedures required in TAPP inguinal hernia repair. Fifteen general surgeons performed TAPP inguinal hernia repair using our simulator. Their opinions were scored on a 5-point Likert scale. All participants strongly agreed that the 3D-printed physical simulator and organ replica model were highly useful for TAPP inguinal hernia repair training (median, 5 points) and TAPP inguinal hernia repair education (median, 5 points). They felt that the simulator would be effective for TAPP inguinal hernia repair training before entering the operating theater. All surgeons considered that this simulator should be introduced in the residency curriculum. We successfully created a physical simulator for TAPP inguinal hernia repair training using 3D printing technology and a handmade organ replica model created with inexpensive, readily accessible materials. Preoperative TAPP inguinal hernia repair training using this simulator and organ replica model may be of benefit in the training of all surgeons. All general surgeons involved in the present study felt that this simulator and organ replica model should be used in their residency curriculum.

Zielke, Andreas

2005-12-01

Full Text Available Background: The aim of this study was to determine if students are suitable candidates to assess the learning effect through a virtual reality laparoscopy simulator (LapSim®. Materials and methods: 14 medical students in their final year without any previous experience with a virtual reality simulator were recruited as subjects. In order to establish a "base line" all subjects were instructed into the "clip application" task - a basis module of the laparoscopy simulator - at the beginning of the study. They were then randomized into two groups. Group A (n=7 had parameter adjusted to an easy level of performance, while group B (n=7 was adjusted to a difficult level. In both levels, errors simulated clinically relevant situations such as vessel rupture and subsequent bleeding. Each participant had to repeat the clip application task ten times consecutively. Results: The mean time for completion ten repetitions was 15 min pro participant in group A and 20 min in group B. From the first to the fifth repetition group A improved significantly the task completion time from 238.9 s to 103.3 s (p<0.007 consecutively and also improved the error score from 312 to 177 (p<0.07. At the tenth repetition they increased the task completion time from 103.3 s to 152.2 s (p<0.09 and increased their error score from 177 to 202 (p=0.25. From the first to the fifth repetition group B also improved the task completion time from 131.6 s to 104.5 s (p<0.31 consecutively and improved the error score from 235 to 208 (p<0.32 but at the tenth repetition they increased the task completion time from 104.5 s to 142.4 s (p<0.45 and clearly increased their error score from 208 to 244 (p<0.38. Conclusion: These results suggest that medical students, who lack clinical background, may be not suitable candidates for assessing the efficiency of a training model using a laparoscopy simulator. If medical students are appointed for such studies, they should receive didactic sessions in

The aim of our study was to compare the accuracy of CT and 18 F-FDG PET for detecting peritoneal metastasis in patients with gastric carcinoma. One-hundred-twelve patients who underwent a histologic confirmative exam or treatment (laparotomy, n = 107; diagnostic laparoscopy, n = 4; peritoneal washing cytology, n = 1) were retrospectively enrolled. All the patients underwent CT and 18 F-FDG PET scanning for their preoperative evaluation. The sensitivities, specificities and accuracies of CT and 18 FFDG PET imaging for the detection of peritoneal metastasis were calculated and then compared using Fisher's exact probability test (p 18 F-FDG PET imaging for detecting peritoneal metastasis. Based on the original preoperative reports, CT and 18 F-FDG PET showed sensitivities of 76.5% and 35.3% (p = 0.037), specificities of 91.6% and 98.9% (p = 0.035), respectively, and equal accuracies of 89.3% (p = 1.0). The receptor operating characteristics curve analysis showed a significantly higher diagnostic performance for CT (Az 0.878) than for PET (Az = 0.686) (p 0.004). The interobserver agreement for detecting peritoneal metastasis was good (κ value = 0.684) for CT and moderate ((κ value = 0.460) for PET. For the detection of peritoneal metastasis, CT was more sensitive and showed a higher diagnostic performance than PET, although CT had a relatively lower specificity than did PET

Ovotesticular disorder of sexual development (DSD) is characterized by the presence of both ovarian and testicular tissues in the same individual. The most common karyotype is 46,XX. Here, we report the case of a boy with a 46,XX/47,XXY karyotype diagnosed as ovotesticular DSD by gonadal biopsy. A 5-month-old boy presented with hypospadias, unilateral cryptorchidism, and a micropenis. Pelvic magnetic resonance imaging revealed a suspicious gonad tissue that is solid in structure in the right scrotum and a suspicious gonad that is cystic in structure in the left inguinal canal. He underwent a diagnostic laparoscopy. Cytogenetic analysis of peripheral blood revealed a 46,XX/47,XXY karyotype. Histopathologic examination of the left gonad showed ovarian tissue containing primordial follicles with ipsilateral undifferentiated tuba uterina. The right gonad showed immature testis tissue. He underwent left gonadectomy and hypospadias repair, and was raised as a male. Through this rare case, we highlight the importance of histological and cytogenetic investigation in DSD.

A Meckel diverticulum is an embryonic remnant of the omphalomesenteric duct that occurs in approximately 2% of the population. Most are asymptomatic; however, they are vulnerable to inflammation with subsequent consequences including diverticulitis and perforation. We report an 11-year-old boy who underwent laparoscopic appendectomy for perforated appendicitis at an outside institution. During his convalescence he underwent percutaneous drainage of a presumed postoperative abscess. A follow-up drain study demonstrated an enteric fistula. The drain was slowly removed from the abdomen over a period of 1 week. Three weeks following drain removal the patient reported recurrent nausea and abdominal pain. A CT scan demonstrated a 3.7-cm rim-enhancing air-fluid level with dependent contrast consistent with persistent enteric fistula and abscess. Exploratory laparoscopy was performed, at which time a Meckel diverticulum was identified and resected. This case highlights the diagnostic challenge and limitations of conventional radiology in complicated Meckel diverticulum. (orig.)

To determine whether providing additional information to the standard consent process, in the form of a multimedia module (MM), improves patient knowledge about operative laparoscopy without increasing anxiety. Randomized controlled trial (Canadian Task Force classification I). Two outpatient gynecologic clinics, one in a private hospital and the other in a public teaching hospital. Forty-one women aged 19 to 51 years (median, 35.6 years) requiring operative laparoscopy for investigation and treatment of pelvic pain. Following the standard informed consent process, patients were randomized to watch the MM (intervention group, n = 21) or not (control group, n = 20). The surgeon was blinded to the group assignments. All patients completed a knowledge questionnaire and the Spielberger short-form State-Trait Anxiety Inventory. Six weeks after recruitment, patients completed the knowledge questionnaire and the State-Trait Anxiety Inventory a second time to assess knowledge retention and anxiety scores. Patient knowledge of operative laparoscopy, anxiety level, and acceptance of the MM were recorded. The MM intervention group demonstrated superior knowledge scores. Mean (SE) score in the MM group was 11.3 (0.49), and in the control group was 7.9 (0.50) (p <.001) (maximum score, 14). This did not translate into improved knowledge scores 6 weeks later; the score in the MM group was 8.4 (0.53) vs. 7.8 (0.50) in the control group (p = .44). There was no difference in anxiety levels between the groups at intervention or after 6 weeks. Overall, patients found the MM acceptable, and 18 women (86%) in the intervention group and 12 (60%) in the control group stated they would prefer this style of informed consent in the future. Use of an MM enhances the informed consent process by improving patient knowledge, in the short term, without increasing anxiety. Copyright © 2014 AAGL. Published by Elsevier Inc.

2013-01-01

Full Text Available The aim of the study was to determine the concentration of lipid peroxidation products, the activity of selected antioxidant and lysosomal enzymes, and protease inhibitor in patients with renal cell carcinoma who underwent radical nephrectomy. The studied group included 44 patients: 21 of them underwent open surgery, while 23 underwent laparoscopy. Blood samples were collected three times: before treatment and 12 hours and five days after nephrectomy. In blood of participants, the concentration of thiobarbituric acid reactive substances (TBARS, the activity of catalase (CAT, superoxide dismutase (SOD and glutathione peroxidase (GPx, and the activity of acid phosphatase (AcP, arylsulfatase (ASA, cathepsin D (CTSD, and α1-antitrypsin (AAT were assayed. No statistically significant differences in investigated parameters were found between studied groups. Moreover, TBARS concentration and CAT, SOD, and GPx activity were not altered in the course of both types of surgery. Five days after both open and laparoscopic nephrectomy techniques, AAT activity was higher than its activity 12 hours after the procedure. The obtained results suggest that laparoscopy may be used for nephrectomy as effectively as open surgery without creating greater oxidative stress. Reduced period of convalescence at patients treated with laparoscopy may be due to less severe response of acute-phase proteins.

The aim of this retrospective study was to assess the feasibility, safety and efficacy of the laparoscopic approach in the management of perforated peptic ulcers. From January 1997 to December 2002, all patients referred to our community hospital for abdominal surgical emergencies were routinely managed by laparoscopic surgery. A review was carried out on 39 consecutive patients suffering from perforated peptic ulcers with or without generalised peritonitis. The study population comprised 24 male and 15 female patients, aged 30 to 94 years (mean age: 62 +/- 18). Laparoscopic repair was attempted in all patients. Laparoscopy afforded the correct diagnosis in all cases. Laparoscopic peritoneal washout (irrigation and suction of the entire abdominal cavity) with simple suture of the perforation proved successful in 34 patients. An additional omental patching was performed in 15 of these cases. Conversion to conventional open surgery was necessary in 5 patients. The morbidity and mortality rates were 13% and 10%, respectively. The mean operative time was 77 minutes (range: 40-120) and the mean hospital stay 9 days (range: 3-22). Laparoscopic repair of perforated ulcers is technically feasible but requires sound experience in laparoscopic abdominal emergencies. This study shows that the mini-invasive procedure is safe and effective, offering a valid alternative to traditional laparotomy.

A randomized, single-blind trial of two spinal anesthetic solutions for outpatient laparoscopy was conducted to compare intraoperative conditions and postoperative recovery. Thirty women (ASA physical status I and II) were assigned to one of two groups. Group I patients received a small-dose hypobaric solution of 1% lidocaine 25 mg made up to 3 mL by the addition of fentanyl 25 micrograms. Group II patients received a conventional-dose hyperbaric solution of 5% lidocaine 75 mg (in 7.5% dextrose) made up to 3 mL by the addition of 1.5 mL 10% dextrose. All patients received 500 mL of crystalloid preloading. Spinal anesthesia was performed at L2-3 or L3-4 with a 27-gauge Quincke point needle. Surgery commenced when the level of sensory anesthesia reached T-6. Intraoperative hypotension requiring treatment with ephedrine occurred in 54% of Group II patients but not in any Group I patients. Median (range) time for full motor recovery was 50 (0-95) min in Group I patients compared to 90 (50-120) min in Group II patients (P = 0.0005). Sensory recovery also occurred faster in Group I patients (100 +/- 22 min) compared with Group II patients (140 +/- 27 min, P = 0.0001). Postoperative headache occurred in 38% of all patients and 70% of these were postural in nature. Oral analgesia was the only treatment required. Spinal anesthesia did not result in a significant incidence of postoperative backache. On follow-up, 96% said they found spinal needle insertion acceptable, 93% found surgery comfortable, and 90% said they would request spinal anesthesia for laparoscopy in future. Overall, this study found spinal anesthesia for outpatient laparoscopy to have high patient acceptance and a comparable complication rate to other studies. The small-dose hypobaric lidocaine-fentanyl technique has advantages over conventional-dose hyperbaric lidocaine of no hypotension and faster recovery.

2006-08-01

An 86-year-old man was admitted to our department with complaints of intermittent upper abdominal pain. Ultrasonography of the abdomen showed dilated extrahepatic bile ducts containing stones; however, the gallbladder was not clearly identified. Magnetic resonance cholangiopancreatography showed dilated extrahepatic ducts and choledocholithiasis without gallbladder visualization. The stone extraction was performed with endoscopic sphincterotomy. Three-dimensional images using spiral-computed tomography after intravenous-infusion cholangiography clearly demonstrated an obstruction of the cystic duct. The patient was scheduled for laparoscopic cholecystectomy. At laparoscopy, the gallbladder fossa was not identified on the undersurface of the liver. Despite a thorough examination of the intrahepatic (left-sided within the lesser omentum), retroperitoneal, retrohepatic (within the falciform ligament), retroduodenal, and retropancreatic areas using laparoscopic ultrasonography, the gallbladder was not found. After careful dissection of the hepatoduodenal ligament, the dilated extrahepatic bile duct and a 1-cm length of hypoplastic cystic duct were found. Gallbladder agenesis is usually accompanied by the lack of the cystic duct. The present case is the third report of gallbladder agenesis with a patent or hypoplastic cystic duct.

To evaluate the value of serum microRNA-122 (miR-122) and miR-199a as reliable noninvasive biomarkers in the diagnosis of endometriosis. During 2015-2016, at a teaching hospital in Egypt, a prospective cohort study was conducted on 45 women with pelvic endometriosis and 35 women who underwent laparoscopy for pelvic pain but were not diagnosed with endometriosis. Blood and peritoneal fluid (PF) samples were collected; interleukin-6 (IL-6) was detected by enzyme-linked immunosorbent assay and miR-122 and miR-199a expression was measured by quantitative real-time polymerase chain reaction. The serum and PF levels of IL-6, miR-122, and miR-199a were significantly higher in women with endometriosis than in controls (Pendometriosis. Serum miR-122 and miR-199a were significantly increased in endometriosis, indicating that these microRNAs might serve as biomarkers for the diagnosis of endometriosis. © 2017 International Federation of Gynecology and Obstetrics.

To compare the efficacy of whole genome sequencing (WGS) with targeted next-generation sequencing (NGS) in the diagnosis of inherited retinal disease (IRD). Case series. A total of 562 patients diagnosed with IRD. We performed a direct comparative analysis of current molecular diagnostics with WGS. We retrospectively reviewed the findings from a diagnostic NGS DNA test for 562 patients with IRD. A subset of 46 of 562 patients (encompassing potential clinical outcomes of diagnostic analysis) also underwent WGS, and we compared mutation detection rates and molecular diagnostic yields. In addition, we compared the sensitivity and specificity of the 2 techniques to identify known single nucleotide variants (SNVs) using 6 control samples with publically available genotype data. Diagnostic yield of genomic testing. Across known disease-causing genes, targeted NGS and WGS achieved similar levels of sensitivity and specificity for SNV detection. However, WGS also identified 14 clinically relevant genetic variants through WGS that had not been identified by NGS diagnostic testing for the 46 individuals with IRD. These variants included large deletions and variants in noncoding regions of the genome. Identification of these variants confirmed a molecular diagnosis of IRD for 11 of the 33 individuals referred for WGS who had not obtained a molecular diagnosis through targeted NGS testing. Weighted estimates, accounting for population structure, suggest that WGS methods could result in an overall 29% (95% confidence interval, 15-45) uplift in diagnostic yield. We show that WGS methods can detect disease-causing genetic variants missed by current NGS diagnostic methodologies for IRD and thereby demonstrate the clinical utility and additional value of WGS.

Full Text Available Background. Invagination of the vermiform appendix is a very rare occurrence. We summarize epidemiologic and etiologic factors, types of classification, symtomatology, diagnostic features and treatment.Patients and treatment. The authors present 49-years old female with long-standing abdominal pains, who came in our hospital due to acute exacerbation with sever abdominal pain. Because of progressive symptoms and sensitivity in the right-lower abdominal quadrant a diagnostic laparoscopy was performed. An anomaly of cecum and the absence of appendix vermiformis have forced us to proceed with laparotomy in McBurnay point. After cecotomy an invaginated gangrenous appendix was found. The histological examination revealed endometriosis.Conclusions. By presenting this extremely rare pathology we also want to emphasize the important role of diagnostic laparoscopy in front of acute abdomen.

Diagnostic management of pulmonary arteriovenous malformations in children

1988-01-01

Pulmonary arteriovenous malformations (PAVMs) are uncommon in childhood and adolescence. In the past 8 years, the authors have studied 21 patients. Symptoms included dyspnea (n = 13), epistaxis (n = 13), migraine headaches (n = 9), transient ischemic attacks (n = 6), hemoptysis (n = 3), and seizures (n = 3). Seventeen patients had hereditary hemorrhagic telangiectasis (HHT). All patients underwent diagnostic angiography, and 19 underwent detachable balloon embolotherapy. In patients with focal PAVMs, treatment increased the average preembolization arterial oxygen pressure of 63 mm Hg to a posttreatment average of 83 mm Hg. Marked clinical improvement was documented at follow-up (3 - 90 months), except in four patients with diffuse disease. Six patients underwent repeated embolotherapy of PAVMs that were not occluded initially. The authors conclude that PAVMs in children and adolescents are frequently symptomatic and associated with HHT. Detachable balloon embolotherapy is a safe and effective therapeutic modality

Risk factors for failed first-trimester surgical abortion include endometrial distortion caused by leiomyomas, uterine anomalies and malposition and cervical stenosis. This report introduces intrauterine adhesions as an additional risk factor. A multiparous woman presented for pregnancy termination at 6 weeks' gestation. Three suction-curettage attempts failed to remove what appeared to be an intrauterine pregnancy. Rising beta-hCG levels and concern for an interstitial ectopic pregnancy prompted a diagnostic laparoscopy and exploratory laparotomy without the identification of an ectopic pregnancy. After methotrexate treatment failed, the patient underwent ultrasound-guided hysteroscopy and suction curettage using a cannula with a whistle-cut aperture for the successful removal of a pregnancy implanted behind intrauterine adhesions. Intrauterine adhesions are a cause of failed surgical abortion. Ultrasound-guided hysteroscopy may be required for diagnosis.

PTP1B is involved in the oncogenesis of breast cancer. In addition, neoadjuvant therapy has been widely used in breast cancer; thus, a measurement to assess survival improvement could be pathological complete response (pCR). Our objective was to associate PTP1B overexpression with outcomes of breast cancer patients who underwent neoadjuvant chemotherapy. Forty-six specimens were included. Diagnostic biopsies were immunostained using anti-PTP1B antibody. Expression was categorized as negative (<5%) and overexpression (≥5%). Patients' responses were graded according to the Miller-Payne system. Sixty-three percent of patients overexpressed PTP1B. There was no significant association between PTP1B overexpression and pCR ( P = 0.2). However, when associated with intrinsic subtypes, overexpression was higher in human epidermal growth factor receptor 2-positive-enriched specimens ( P = 0.02). Ten-year progression-free survival showed no differences. Our preliminary results do not show an association between PTP1B over-expression and pCR; however, given the limited sample and heterogeneous treatment in our cohort, this hypothesis cannot be excluded.

To study the utility of ultrasound and computed tomography (CT) in case of suspected appendicitis. To determine the diagnostic yield in terms of different clinical contexts and patient characteristics. to assess the costs and benefits of introducing these techniques and propose a protocol for their use. Negative appendectomies, complications and length of hospital stay in a group of 152 patients with suspected appendicitis who underwent ultrasound and CT were compared with those of 180 patients who underwent appendectomy during the same time period, but had not been selected for the first group: these patients costs for each group were calculated. In the first group, the diagnostic value of the clinical signs was also evaluated. The reliability of the clinical signs was limited, while the results with ultrasound and CT were excellent. The incidence of negative appendectomy was 9.6% in the study group and 12.2% in the control group. Moreover, there were fewer complications and a shorter hospital stay in the first group. Among men, however, the rate of negative appendectomy was lower in the control group. The cost of using ultrasound and CT in the management of appendicitis was only slightly higher than that of the control group. Although ultrasound and CT are not necessary in cases in which the probability of appendicitis is low or in men presenting clear clinical evidence, the use of these techniques is indicated in the remaining cases in which appendicitis is suspected. In children, ultrasound is the technique of choice. In all other patients, if negative results are obtained with one of the two techniques, the other should be performed. (Author) 49 refs

Modern management of severe acute complicated diverticulitis continues to evolve towards more conservative and minimally invasive strategies. Although open sigmoid colectomy with end colostomy remains the most commonly used procedure for the treatment of perforated diverticulitis with purulent/faeculent peritonitis, recent major advances challenged this traditional approach, including the increasing attitude towards primary anastomosis as an alternative to end colostomy and use of laparoscopic approach for urgent colectomy. Provided an accurate patients selection, having the necessary haemodynamic stability, pneumoperitoneum is established with open Hasson technique and diagnostic laparoscopy is performed. If faeculent peritonitis (Hinchey IV perforated diverticulitis) is found, laparoscopy can be continued and a further three working ports are placed using bladeless trocars, as in traditional laparoscopic sigmoidectomy, with the addition of fourth trocar in left flank. The feacal matter is aspirated either with large-size suction devices or, in case of free solid stools, these can be removed with novel application of tight sealing endobags, which can be used for scooping the feacal content out and for its protected retrieval. After decontamination, a sigmoid colectomy is performed in the traditional laparoscopic fashion. The sigmoid is fully mobilised from the retroperitoneum, and mesocolon is divided up to the origin of left colic vessels. Whenever mesentery has extremely inflamed and thickened oedematous tissues, an endostapler with vascular load can be used to avoid vascular selective ligatures. Splenic flexure should be appropriately mobilised. The specimen is extracted through mini-Pfannenstiel incision with muscle splitting technique. Transanal colo-rectal anastomosis is fashioned. Air-leak test must be performed and drains placed where appropriate. The video shows operative technique for a single-stage, entirely laparoscopic, washout and sigmoid colectomy

We aimed to assess the role of medical thoracoscopy in patients with undiagnosed pleural effusion. Patiens presenting with pleural effusion underwent three pleural aspirations. Patients in whom pleural fluid analysis was inconclusive underwent closed pleural biopsy for diagnostic confirmation. Patients in whom closed pleural biopsy was incolcusive underwent medical thoracoscopy using a rigid thoracoscope with a viewing angle of zero degrees was done under local anaesthesia and sedation with the patient lying in lateral decubitus position with the affected side up. Biopsy specimens from parietal pleura were obtained under direct vision and were sent for histopathological examination. Of the 128 patients with pleural effusion who were studied, pleural fluid examination established the diagnosis in 81 (malignancy 33, tuberculosis 33, pyogenic 14 and fungal 1); 47 patients underwent closed pleural biopsy and a diagnosis was made in 28 patients (malignancy 24, tuberculosis 4). The remaining 19 patients underwent medical thoracoscopy and pleural biopsy and the aetiological diagnosis could be confirmed in 13 of the 19 patients (69%) (adenocarcinoma 10, poorly differentiated carcinoma 2 and mesothelioma 1). Medical thoracoscopy is a useful tool for the diagnosis of pleural diseases. The procedure is safe with minimal complications.

There is a high morbidity rate after digestive surgery in patients with nutritional disorders such as high body mass index and depletion of skeletal muscle. The ratio of psoas muscle area to trunk area was defined as the Psoas and All trunk Ratio (PandA Ratio) and used as an index of the balance between muscle and adipose tissue. This ratio was determined in 77 patients undergoing laparoscopy-assisted gastrectomy (LAG) for gastric cancer. Patients were classified into groups with and without postoperative complications. Clinicopathological factors were compared between the groups, and relationships of PandA Ratio with other nutritional indices were examined. PandA Ratios were also analyzed in males and females in each Clavien-Dindo grade. Complications developed in 22 patients (28.6%) after LAG. The PandA Ratio was significantly lower in patients with complications in univariate (2.76 ± 0.22% versus 3.66 ± 0.14%, P = 0.0009) and multivariate (P = 0.0064) analyses. A low PandA Ratio was also associated with more severe complications in males. Measurement of the areas of the psoas muscle and trunk on CT is useful for evaluation of the balance between skeletal and adipose tissue. The PandA Ratio derived from these measurements is a predictor of the clinical course after LAG in males. Copyright © 2017 Elsevier Inc. All rights reserved.

With recent advances in radiologic diagnostic procedures, the use of diagnostic peritoneal lavage (DPL) has markedly declined. In this study, we reviewed data to reevaluate the role of DPL in the diagnosis of hollow organ perforation in patients with blunt abdominal trauma. Adult patients who had sustained blunt abdominal trauma and who were hemodynamically stable after initial resuscitation underwent an abdominal computed tomographic (CT) scan. Diagnostic peritoneal lavage was performed for patients who were indicated to receive nonoperative management and where hollow organ perforation could not be ruled out. During a 60-month period, 64 patients who had received abdominal CT scanning underwent DPL. Nineteen patients were diagnosed as having a positive DPL based on cell count ratio of 1 or higher. There were 4 patients who sustained small bowel perforation. The sensitivity and specificity of the cell count ratio for a hollow organ perforation in this study were 100% and 75%, respectively. No missed hollow organ perforations were detected. For patients with blunt abdominal trauma and hemoperitoneum who plan to receive nonoperative management, DPL is still a useful tool to exclude hollow organ perforation that is undetected by CT.

Frobenius, W.; Bogdan, C.

2015-01-01

The majority of uncomplicated vulvovaginal complaints (e.g. bacterial vaginosis, vulvovaginal candidiasis, trichomoniasis) can be detected with uncomplicated basic infectiological tests and can usually be treated effectively without requiring further diagnostic procedures. Tests include measurement of vaginal pH, preparation and assessment of wet mount slides prepared from vaginal or cervical discharge, and the correct clinical and microbiological classification of findings. In Germany, at least in recent years, this has not been sufficiently taught or practiced. As new regulations on specialist gynecologic training in Germany are currently being drawn up, this overview provides basic information on gynecologic infectiology and summarizes clinically relevant aspects of recent microbiological findings on the physiology and pathology of vaginal flora. The clinical signs and symptoms of aerobic vaginitis, the pathogenesis of which is still not completely understood, are also reviewed. Finally, the symptoms, indications and risk factors for pelvic inflammatory disease (PID) are presented. In contrast to the above-listed infections, PID requires immediate culture of the pathogen from samples (e.g. obtained by laparoscopy) with microbiological diagnostic procedures carried out by specialist laboratories. A schematic summary of all pathologies discussed here is presented. PMID:26028693

Full Text Available Background. Intra-abdominal metastases of invasive lobular breast cancer (ILBC may be insidious. We report a case of metastatic ILBC that presented with dysphagia within weeks of a negative mammogram and before the development of intra-abdominal symptoms. Case. A 70-year-old female developed esophageal dysphagia. She underwent EGD which showed a short segment of stricture of the distal esophagus without significant mucosal changes. Biopsy was unremarkable and patient underwent lower esophageal sphincter (LES dilation. Severe progressive dysphagia led to esophageal impaction and three LES dilatations. CT scan showed bilateral pleural effusions, more prominent on right side, and ascites. The pleural effusions were transudative. Repeat EGD with biopsy showed lymphocytic esophagitis, and she was started on swallowed fluticasone. Abdominal ultrasound with Doppler showed that the main portal vein had atypical turbulent flow that was felt to possibly be due to retroperitoneal process. The patient underwent diagnostic laparoscopy which revealed diffuse punctate lesions on the peritoneum. Pathology was consistent with metastatic ILBC. Conclusion. Dysphagia in the setting of peritoneal carcinomatosis from metastatic ILBC is a rare finding. The case highlights the importance of metastatic ILBC as a differential diagnosis for female patients with progressive dysphagia and associated ascites or pleural effusions.

At present, the acute pelvic inflammatory disease is considered a syndrome clinically attributed to the ascending passage of microorganisms from the vagina to the cervix, the endometrium and the Fallopian's tubes. It is also capable of disseminating to the neighbouring structures. The objective of this paper was to know the behaviour of the disease, the efficiency of some diagnostic aids and procedures, the performance of the haematological tests, and to identify the most common germs to define the further conduct. METHODS. The study group consisted of 108 females seen at "Julio Trigo López" Hospital due to an acute inflammatory pelvic disease. The sample was selected at random and variables such as general and health data and data from the gynecoobstetric history were registered. Vaginal manipulation, with anaesthesia or without it, puncture of Douglas' pouch, ultrasound, laparoscopy, red-blood cell count, white-blood cell count, and erythrosedimentation were used to make the diagnosis. Laparoscopy was used in all cases as a confirmatory test. RESULTS. Most of the patients were aged 20-25. Abdominal pain (98.1 % and leucorrhoea (30.6 % predominated as clinical symptomatology. A high incidence of this disease was observed in females at reproductive age, with 2 or more pregnancies and abortions and history of implanted intrauterine device. Moreover, there was a diagnostic concordance between the results of the vaginal manipulation and ultrasound, on comparing them with laparoscopy. The least specific test was vaginal manipulation (20.5 % and the predictive values of the lowest positive test were obtained with the same procedure (64.6 %, as well as with erythrosedimentation (70 %. Therefore, ultrasound proved to be the most effective diagnostic aid (87,5 % after laparoscopy. CONCLUSIONS. It was concluded that ultrasound (77 % is the most effective test

We aimed at assessing the effect of using a "Funada-kit II" device during laparoscopy-assisted percutaneous endoscopic gastrostomy (Lap-PEG), by reviewing 29 cases of Lap-PEG we performed from 2001 to 2011. We started using the "Funada-kit II" (CREATE MEDIC CO., Kanagawa, Japan) device with two parallel needles to puncture the stomach and assist suturing the anterior gastric wall to the anterior abdominal wall during Lap-PEG in 2011 (F-PEG). By introducing a loop through the lumen of one needle which allows placement of a suture introduced through the lumen of the other needle. Once repeated, the stomach can be pexied at two points, approximately 2 cm apart. We compared Lap-PEG (n = 23) with F-PEG (n = 6) where the mean ages and weights at surgery and sex ratios were similar. All cases were uneventful without intraoperative complications, although one postoperative wound infection occurred in a Lap-PEG case. There were no differences in the duration of analgesia, time taken to commence tube feeding, and return to full feeding. However, mean operating time was significantly shorter in F-PEG (28.1 min) versus Lap-PEG (46.1 min) p < 0.05. As per results F-PEG would appear to be as safe as Lap-PEG, but much quicker.

To investigate whether preclinical laparoscopy training offers a benefit over standard apprenticeship training and apprenticeship training in combination with simulation training. This randomized controlled trial consisted of 3 groups of first-year surgical registrars receiving a different teaching method in laparoscopic surgery. The KU LEUVEN Faculty of Medicine is the largest medical faculty in Belgium. Thirty final-year medical students starting a general surgical career in the next academic year. Thirty final-year medical students were randomized into 3 groups, which differed in the way they were exposed to laparoscopic simulation training but were comparable in regard to ambidexterity, sex, age, and laparoscopic psychomotoric skills. The control group received only clinical training during surgical residentship, whereas the interval group received clinical training in combination with simulation training. The registrars were allowed to do deliberate practice. The Centre for Surgical Technologies Preclinical Training Programme (CST PTP) group received a preclinical simulation course during the final year as medical students, but was not exposed to any extra simulation training during surgical residentship. At the beginning of surgical residentship and 6 months later, all subjects performed a standardized suturing task and a laparoscopic cholecystectomy in a POP Trainer. All procedures were recorded together with time and motion tracking parameters. All videos were scored by a blinded observer using global rating scales. At baseline the 3 groups were comparable. At 6 months, for suturing, the CST PTP group was better than both the other groups with respect to time, checklist, and amount of movements. The interval group was better than the control group on only the time and checklist score. For the cholecystectomy evaluation, there was a statistical difference between the CST PTP study group and both other groups on all evaluation scales in favor of the CST PTP

Full Text Available Hepatic biopsy was realized through laparoscopy with simultaneous cauterization in the present study, whose principal aim was to evaluate the efficacy of the applied method and to study its effects in the liver of healthy dogs. Furthermore, we tried to verify the main hematological and chemistry profile alterations related to the hepatic function, and to investigate the viability of the fragments collected by histopathology. To attain this objective, 21 clinically healthy dogs, weighing between 10 and 15kg were submitted to hepatic biopsy with forceps connected to the cautery. Cautery was performed by applying radiofrequency energy at 45 watts. Forty-two hepatic biopsies through laparoscopy were conducted in the animals. At group I one hepatic fragment per animal was collected, at group II two hepatic fragments per animal were collected, and at group III three fragments were collected. Hematocrit and alanine-aminotransferase measurements were employed to evaluate the animals at the pre-operative period, at four and six hour post-operative, and at day 30 post-operative. The results revealed that the procedure was safe and effective for hepatic biopsy in dogs. There were no clinical alterations related to the technique. The fragments collected were viable for histopathology. Hepatic biopsy through laparoscopy with simultaneous cauterization is an effective and usefull method in dogs.Este estudo visou avaliar a eficácia do método de biópsia hepática laparoscópica por cauterização e estudar os seus efeitos no fígado de cães sadios.

Traumatic diaphragm injuries (TDI) pose both diagnostic and therapeutic challenges in both the acute and chronic phases. There are no published practice management guidelines to date for TDI. We aim to formulate a practice management guideline for TDI using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology. The working group formulated five Patient, Intervention, Comparator, Outcome (PICO) questions regarding the following topics: 1) diagnostic approach (laparoscopy vs. computed tomography); 2) non-operative management of penetrating right-sided injuries; 3) surgical approach (abdominal or thoracic) for acute TDI, including 4) the use of laparoscopy; and 5) surgical approach (abdominal or thoracic) for delayed TDI. A systematic review was undertaken and last updated December 2016. RevMan 5 (Cochran Collaboration) and GRADEpro (Grade Working Group) software were utilized. Recommendations were voted on by working group members. Consensus was obtained for each recommendation. A total of 56 articles were utilized to formulate the recommendations. Most studies were retrospective case series with variable reporting of outcomes measures and outcomes frequently not stratified to intervention or comparator. The overall quality of the evidence was very low for all PICOs. Therefore, only conditional recommendations could be made. Recommendations were made in favor of laparoscopy over CT for diagnosis, non-operative vs. operative approach for right-sided penetrating injuries, abdominal vs. thoracic approach for acute TDI, and laparoscopy (with the appropriate skill set and resources) vs. open approach for isolated TDI. No recommendation could be made for the preferred operative approach for delayed TDI. Very low-quality evidence precluded any strong recommendations. Further study of the diagnostic and therapeutic approaches to TDI is warranted. Guideline LEVEL OF EVIDENCE: 4.

Torsion of the omentum is twisting along its long axis and a rare cause of acute abdomen. Depending on associated conditions, it is classified as primary and secondary. It may mimic different pathologies presenting as acute abdomen, most common of them being acute appendicitis. Current choice for management of omental torsion is laparoscopic surgery. We present two cases of omental torsion of two boys who presented with abdominal pain, nausea and vomiting and underwent emergency laparoscopy. Omental torsion is very rare, and its diagnosis is usually made only after surgery. At laparoscopy, omental torsion is suspected when the appendix is normal and the symptoms and findings of torsion are present. Laparoscopy is a safe and effective approach for the diagnosis and management of omental torsion, with the advantages of reduced postoperative pain and hospital stay. © The Author(s) 2015.

A laparoscopic approach to total proctocolectomy with IPAA has been suggested to have better short-term outcomes and cosmesis, whereas open surgery by midline incision may result in shorter operative times. We hypothesized that a modified Pfannenstiel open approach would combine the advantages of both techniques. The purpose of this study was to compare outcomes of open total proctocolectomy with IPAA using a modified Pfannenstiel incision versus those following the laparoscopic approach. This was a retrospective study comparing patients submitted to open IPAA using modified Pfannenstiel incision versus laparoscopy from 1998 to 2014. The study was conducted at a high-volume tertiary referral center. Among 1275 patients, 119 patients underwent the laparoscopic approach and 33 underwent the modified Pfannenstiel approach. Short- and long-term outcomes were evaluated, and quality-of-life questionnaires were assessed. Patients who underwent the modified Pfannenstiel approach were younger, more often women, and had lower BMI and ASA classification compared with those who underwent laparoscopy. Surgical time was lower in Pfannenstiel, and no difference was observed in length of hospital stay. No difference was observed in postoperative complications, pouch failure rate, or quality of life. Patients were then matched 1:1 by diagnosis, sex, age (±5 y) and BMI (±5 kg/m). The Pfannenstiel approach still had a shorter surgical time. No difference was observed in the length of hospital stay, complications, pouch failure, or quality of life. In long-term follow-up, pouchitis symptoms occurred more frequently in Pfannenstiel (mean follow-up = 7.3 y), and seepage was more frequently observed in the laparoscopy group (mean follow-up = 4.2 y). These differences were not observed in matched patients. The study was limited by its retrospective design and inherent selection bias. The modified Pfannenstiel approach provides equivalent short- and long-term outcomes and similar

Mistakes have been made by the use of CT in diagnosing children with suspected appendicitis. Although others have reported the frequency of diagnostic errors, we were unable to find any studies that addressed the specific situations in which diagnostic errors occurred in children with suspected appendicitis. To investigate the frequency and type of diagnostic errors resulting from CT of children with suspected appendicitis when compared to surgical and pathological diagnosis. We reviewed imaging, clinical and pathological data on 1,207 consecutive pediatric patients who underwent CT examination for suspected appendicitis. Imaging findings were categorized as false-positive, false-negative, or indeterminate. Errors were classified as interpretative, technical or unavoidable. Concordance between surgical and pathological findings was also evaluated. The imaging findings of 34 patients (2.8%) were discrepant with the pathological examination or clinical follow-up. The errors in 23 cases were classified as interpretive (68%) and 11 as unavoidable (32%), and no errors were classified as technical. There were 23 false-positive errors (68%), 6 false-negative errors (18%), and 5 indeterminate imaging studies (15%). Isolated CT findings of an enlarged (greater than 6 mm) appendix, fat stranding, thickened bowel or non-visualization of the distal appendix were the most common false-positive CT findings. Of these 34 patients, 22 underwent appendectomy, with 10 (45%) having discordant surgical and pathological findings. (orig.)

Genital tuberculosis (GTB) is a potent contributor to irreversible damage to the reproductive system and infertility in females. As no gold standard diagnostic tool is yet available, clinical suspicion and relatively insensitive approaches such as histopathology, laparoscopy and hysterosalpingogram are currently critical determinants in the diagnosis of GTB. Although a polymerase chain reaction (PCR)-based assay using endometrial tissue seems promising, sampling does require an invasive procedure. We hypothesized that menstrual blood may provide an alternate non-invasive source of samples for PCR-based GTB diagnosis. We enrolled 195 women with primary infertility in whom GTB was suspected. We obtained ethics committee approval from our institution and written informed consent from subjects. Endometrial tissue and menstrual blood was collected from the subjects and culture, histopathology, and multiplex PCR with both sample type was performed for each subject. The sensitivity and specificity of multiplex PCR was, respectively, 90.2 and 86.1% for menstrual blood, 95.8 and 84.3% for endometrial tissue, and 64.8 and 93.2% for histopathology staining. A strong clinical suspicion aided with multiplex PCR using menstrual blood may significantly reduce the diagnostic dilemma for GTB diagnosis in a non-invasive, sensitive, rapid, and cost-effective manner.

Full Text Available Aims: The laparoscopic "Spaghetti Maneuver" consists in holding an organ by its extremity with a grasper and rolling it up around the tool to keep the organ stable and facilitate its traction within a small space. We describe our experience with the "Spaghetti Maneuver" in some minimally invasive procedures. Materials and Methods: We successfully adopted this technique in 13 patients (5F : 8M aged between 6 and 14 years (average age, 10 on whom we performed 7 appendectomies, 2 ureteral reimplantation and 4 cholecystectomies. In all cases, after the first steps, the appendix, the gallbladder and the ureter were rolled around the grasper and easily isolated; hemostasis was thus induced and the organ was mobilized until removal during cholecystectomy and appendectomy, and before the reimplantation in case of ureteral reimplantation. Results: We found that this technique facilitated significantly the acts of holding, isolating and removing, when necessary, the structures involved, which remained constantly within the visual field of the operator. This allowed a very ergonomic work setting, overcoming the problem of the "blind" zone, which represents a dangerous and invisible area out of the operator′s control during laparoscopy. Moreover the isolation maneuvers resulted easier and reduced operating time. Conclusion: We think that this technique is easy to perform and very useful, because it facilitates the dissection of these organs, by harmonizing and stabilizing the force of traction exercised.

This study was performed to determine the malignancy risk of thyroid nodules with isolated macrocalcification and to evaluate the diagnostic efficacy of fine-needle aspiration (FNA) and core needle biopsy (CNB). From May 2008 to December 2014, a total of 44 patients with isolated macrocalcifications were enrolled from 4,081 consecutive patients who underwent FNA or CNB at a single institution. We assessed the malignancy risk of nodules with isolated macrocalcification. We compared the diagnostic results between FNA and CNB, and the diagnostic efficacy of each procedure was evaluated by the rate of inconclusive results. We compared the diagnostic performance for malignancy between FNA and CNB with a criterion of malignant or atypia/follicular lesion of undetermined significance (indeterminate) diagnostic results. We investigated whether the ultrasonographic feature of isolated macrocalcification was predictive of malignancy. The malignancy risk of nodules with isolated macrocalcification was 16.1% in 31 nodules with final diagnoses and 11.4% in all nodules. CNB demonstrated a significantly lower rate of nondiagnostic and inconclusive results than FNA (7.7% vs. 53.8%, P=0.002 and 15.4% vs. 57.7%, P=0.003, respectively) in 26 nodules that underwent both FNA and CNB. CNB showed a marginally higher diagnostic performance for identifying malignancy than FNA (P=0.067). The ultrasonographic features of the anterior margin of isolated macrocalcification were not predictive of malignancy (P>0.999). Thyroid nodules with isolated macrocalcification had a low to intermediate malignancy risk and should not be considered benign nodules. CNB showed a higher diagnostic efficacy than FNA in these nodules.

Despite improvements in surgical instrumentation and techniques, adhesions continue to form after most procedures. Peritoneal adhesions develop in 60-90% of women who undergo major gynecological operations. This adhesion formation causes significant postoperative morbidity such as bowel obstruction (65%), infertility (15-20%), and chronic pelvic pain (40%). To demonstrate the efficacy of a hyaluronic acid product (Hyalobarrier Gel) for the prevention of adhesions in gynecological surgery. From October 2000 to July 2002, 18 women from 26 to 41 years old (mean age 33.66) underwent myomectomy via laparotomy as their first abdominal operation. Between August 2001 and May 2003, the patients underwent a second-look laparoscopy (7 women, 38.9%, 15 sites, 42.8%) or a second-look laparotomy (11 women, 61.1%, 20 sites, 57.1%) during which all the 35 sites corresponding to the previous myomectomies were analyzed. During the second-look procedure the presence, localization and severity of adhesions were evaluated using the Operative Laparoscopy Study Group Classification (OLSG) and American Fertility Society Classification (AFSC). All patients underwent a second-look laparoscopy/laparotomy and only five of 18 (27.7%) showed pelvic adhesions in seven sites (20%) of previous myomectomies. No adhesion was found on the previous sites of myomectomies of pedunculated leiomyomas so, excluding those, adhesions were found in seven of 29 sites of myomectomies (24.1%). The present study emphasizes the need for improved treatments to prevent adhesions, as there is no doubt that adhesions represent one of the major causes of female morbidity.

To compare task performances of novices and experts using advanced high-definition 3D versus 2D optical systems in a surgical simulator model. Fifty medical students (novices in laparoscopy) were randomly assigned to perform five standardized tasks adopted from the Fundamentals of Laparoscopic Surgery (FLS) curriculum in either a 2D or 3D laparoscopy simulator system. In addition, eight experts performed the same tasks. Task performances were evaluated using a validated scoring system of the SAGES/FLS program. Participants were asked to rate 16 items in a questionnaire. Overall task performance of novices was significantly better using stereoscopic visualization. Superiority of performances in 3D reached a level of significance for tasks peg transfer and precision cutting. No significant differences were noted in performances of experts when using either 2D or 3D. Overall performances of experts compared to novices were better in both 2D and 3D. Scorings in the questionnaires showed a tendency toward lower scores in the group of novices using 3D. Stereoscopic imaging significantly improves performance of laparoscopic phantom tasks of novices. The current study confirms earlier data based on a large number of participants and a standardized task and scoring system. Participants felt more confident and comfortable when using a 3D laparoscopic system. However, the question remains open whether these findings translate into faster and safer operations in a clinical setting.

Laparoscopic repair of paraesophageal hernia (PEH) with fundoplication is currently the preferred elective strategy, but emergent cases are often done open without an anti-reflux (AR) procedure. This study examined PEH repair in elective and urgent/emergent settings and investigated patient characteristic influence on the use of adjunctive techniques, such as AR procedures or gastrostomy tube (GT) placement. Utilizing the University HealthSystem Consortium Clinical Database Resource Manager, selected discharge data were retrieved using International Classification of Disease 9 diagnosis codes for PEH and procedure specific codes. Chi-squared and paired t tests were applied (α = 0.05). Discharge data from October 2010 through June 2014 indicated 7950 patients (≥18 years) underwent PEH surgery, 84.7 % were performed laparoscopically and 15.3 % open. 24.6 % of cases were classified urgent/emergent upon admission, and almost 70 % of these were completed laparoscopically. Open paraesophageal hernia repairs (OHR) represented a higher proportion of urgent/emergent cases but were only 30 % of this total. Laparoscopic paraesophageal hernia repair (LHR) patients were more likely to receive an AR procedure in all situations (54.9 % LHR vs. 26.3 % OHR). Almost 90 % of elective PEH repairs in this cohort were laparoscopic. Elective cases were more commonly associated with AR procedures than emergent cases which frequently incorporated GT placement. We demonstrate that laparoscopic PEH repair has become accepted in emergent cases. Open PEH repair is often reserved for emergent surgeries and less commonly includes an AR procedure. Laparoscopy with an AR procedure is clearly the standard of care in elective surgery. The decision to perform an open or laparoscopic surgery, with or without adjunctive techniques, may be based more on the physician's comfort with laparoscopic surgery and surgical practices than the patient's condition. Long-term follow-up studies are

Mesh erosion through the vagina is the most common complication of synthetic mesh used for pelvic organ prolapse repair. However, conventional transvaginal mesh excision has many technical limitations. We aimed at creating and describing a new surgical technique for transvaginal removal of exposed mesh that would enable better exposition and access, thus facilitating optimal treatment. A step-by-step video showing the technique. A university tertiary care hospital. Five patients previously submitted to pelvic organ prolapse repair using synthetic mesh, presenting mesh erosion through the vagina. Mesh excision using a laparoscopy-like operative vaginoscopy in which standard laparoscopic instruments are used through a single-incision laparoscopic surgery port device placed in the vagina. In all cases, a very good exposure of the mesh was achieved, a minimal tissue traction was required, and the procedures were performed in a very ergonomic way. All the patients were discharged on the same day of the surgery and had a painless postoperative course. So far, there have been no cases of relapse. This seems to be a simple, cheap, and valuable minimally invasive technique with many advantages in comparison with the conventional approach. More cases and time are necessary to access its long-term efficacy. It may possibly be used for the management of other conditions. Copyright © 2015 AAGL. Published by Elsevier Inc.

Laparoscopy-assisted gastrectomy (LAG) has been established as a low-invasive surgery for early gastric cancer. However, it remains unknown whether it is applicable also for advanced gastric cancer, mainly because the long-term results of LAG with D2 lymph node dissection for advanced gastric cancer have not been well validated compared with open gastrectomy (OG). A retrospective cohort study was performed to compare LAG and OG with D2 lymph node dissection. For this study, 167 patients (66 LAG and 101 OG patients) who underwent gastrectomy with D2 lymph node dissection for advanced gastric cancer were reviewed. Recurrence-free survival and overall survival time were estimated using Kaplan-Meier curves. Stratified log-rank statistical evaluation was used to compare the difference between the LAG and OG groups stratified by histologic type, pathologic T status, N status, and postoperative adjuvant chemotherapy. The adjusted Cox proportional hazards regression models were used to calculate the hazard ratios (HRs) of LAG. The 5-year recurrence-free survival rate was 89.6% in the LAG group and 75.8% in the OG group (nonsignificant difference; stratified log-rank statistic, 3.11; P = 0.0777). The adjusted HR of recurrence for LAG compared with OG was 0.389 [95% confidence interval (CI) 0.131-1.151]. The 5-year overall survival rate was 94.4% in the LAG group and 78.5% in the OG group (nonsignificant difference; stratified log-rank statistic, 0.4817; P = 0.4877). The adjusted HR of death for LAG compared with OG was 0.633 (95% CI 0.172-2.325). The findings show that LAG with D2 lymph node dissection is acceptable in terms of long-term results for advanced gastric cancer cases and may be applicable for advanced gastric cancer treatment.

Sonography is an alternative method for diagnosis of CTS that can investigate anatomy and probable pathology. The aim of this study is to investigate the multiple sonographic diagnostic criteria and compare its diagnostic value with electrodiagnosis. Materials and Methods:In this descriptive-cross sectional study, 84 wrists (42 patients with CTS and 42 individuals without any clinical signs in upper limb were investigated. Symptomatic patients underwent clinical examination, standard electrodiagnostic evaluation of upper limb and sonographic investigation of median nerve in forearm and wrist. The control group underwent sonographic investigation. Results: Cross Sectional Area (CSA of Median nerve at distal wrist crease, at the level of Hamate hook and Trapezium, the amount of flexor retinaculum bowing, ratio of CSA at the forearm to distal wrist crease and ratio of CSA at the Pisiform level to distal wrist crease had significant difference in the case group compared to the control group (P-value

Intraperitoneal injection of Bupivacaine and Lidocaine in reducing postoperative pain in gynecologic laparoscopic surgeries: a comparative study

Directory of Open Access Journals (Sweden)

Alleyassin A

2007-08-01

Full Text Available Background: As less invasive surgical procedures, such as laparoscopy, become more common, patients can go home soon after the surgery. However, some pain is accompanied by such procedures due to peritoneal stretching, diaphragmatic irritation, or, to a lesser extent, abdominal puncture. It is important to reduce the level of pain to the point that narcotics are not necessary. The administration of opioids for pain after abdominal surgeries is common. The receptors involved seem to be susceptible to blockade with low-dose local anesthesia, although this is subject to some controversy. In this study, we assess and compare the effectiveness of intraperitoneal Bupivacaine and Lidocaine in pain reduction after diagnostic gynecologic laparoscopy in infertility patients. Methods: In this randomized clinical trial, 150 patients admitted to Dr. Shariati Hospital for diagnostic gynecologic laparoscopy were entered into three randomized groups. Group B received Bupivacaine after the diagnostic laparoscopic procedure, group L received Lidocaine and group C, the control group, received a placebo after the surgery, all administered intraperi- toneally. Postsurgerical pain was assessed using the numeric visual analogue scale at 6 and 24 hours after surgery. Results: In group B, the pain scores at 6 and 24 hours after surgery were significantly less than those of group L. Conclusions: Administration of Bupivacaine after diagnostic gynecologic laparoscopic procedures is more effective in pain control than Lidocaine. The effect of this drug is temporary, yet it significantly decreases early postoperative pain, reducing the need for additional postoperative analgesics. Furthermore, the time at which patients can be discharged from the hospital is significantly reduced.

Robotic-assisted laparoscopy (RAL) is being widely accepted in the field of urology as a replacement for conventional laparoscopy (CL). Nevertheless, the process of its integration in clinical routines has been rather spontaneous. To determine the prevalence of robotic systems (RS) in urological clinics in Germany, Austria and Switzerland, the acceptance of RAL among urologists as a replacement for CL and its current use for 25 different urological indications. To elucidate the practice patterns of RAL, a survey at hospitals in Germany, Austria and Switzerland was conducted. All surgically active urology departments in Germany (303), Austria (37) and Switzerland (84) received a questionnaire with questions related to the one-year period prior to the survey. The response rate was 63%. Among the participants, 43% were universities, 45% were tertiary care centres, and 8% were secondary care hospitals. A total of 60 RS (Germany 35, Austria 8, Switzerland 17) were available, and the majority (68%) were operated under public ownership. The perception of RAL and the anticipated superiority of RAL significantly differed between robotic and non-robotic surgeons. For only two urologic indications were more than 50% of the procedures performed using RAL: pyeloplasty (58%) and transperitoneal radical prostatectomy (75%). On average, 35% of robotic surgeons and only 14% of non-robotic surgeons anticipated RAL superiority in some of the 25 indications. This survey provides a detailed insight into RAL implementation in Germany, Austria and Switzerland. RAL is currently limited to a few urological indications with a small number of high-volume robotic centres. These results might suggest that a saturation of clinics using RS has been achieved but that the existing robotic capacities are being utilized ineffectively. The possible reasons for this finding are discussed, and certain strategies to solve these problems are offered. © 2015 S. Karger AG, Basel.

Full Text Available We present the diagnostic inaccuracies encountered in a case of multiple fibroadenoma with malignant transformation. A 30-year-old lady presented with lump in the right breast of one month duration which on clinical examination, X-ray mammogram, sonomammogram were suggestive of multiple fibroadenomas. Fine needle aspiration cytology of the largest lump revealed features of malignancy and a core biopsy showed pleomorphic cells that could not be categorized. Due to the clinical, radiological and pathological diagnostic ambiguity, lumpectomy was performed and frozen section showed features of only conventional fibroadenoma. Representative bits on routine processing showed only features of fibroadenoma. Hence, complete submission of all lumps was done, which revealed fibroadenoma with invasive ductal carcinoma in one. Patient underwent modified radical mastectomy which showed multiple fibroadenomas, focal fibrocystic disease with a focus of residual invasive tumor and metastatic deposit in one axillary lymph node. This case report highlights the diagnostic challenges in detecting malignancy in fibroadenoma and a need for extensive tissue sampling in multiple fibroadenomas to detect the rare occurrence of carcinoma.

Ovariectomy (OVE) is a routine surgical procedure for neutering in small animal practice. Laparoscopy is a new surgical technique which contains advantages such as less trauma, smaller incision and excellent visualization than traditional open surgery. The present study was conducted to examine the feasibility and safety of laparoscopic procedure through two portal comparing with the conventional open surgery for OVE in healthy female bitches (n=16). Dogs were divided in two equal groups. In laparoscopic group, two 5 and 10 mm portals were inserted; First in the umbilicus for introducing the camera and the second, caudal to the umbilicus for inserting the forceps. Laparoscopic procedure involved grasping and tacking the ovary to the abdominal wall, followed by electrocautery, resection and removal of the ovary. In open surgery, routine OVE was conducted through an incision from umbilicus to caudal midline. Mean operative time, total length of scar, blood loss, clinical and blood parameters and all intra and post-operative complications were recorded in both groups. Mean operative time, total length of scar, blood loss and post-operative adhesions were significantly less in laparoscopic group compared with open surgery. In conclusion, laparoscopic OVE is an acceptable procedure due to more advantages in comparison with traditional OVE.

2016-01-01

Full Text Available Introduction: The distinctive features of modern inflammatory diseases are their indolent course and predisposition to chronicity. Chronic inflammation is the basis for the development of serious disorders, including autoimmune and oncologic ones, and a  cause of major functional abnormalities of the human body. Diagnostics of chronic inflammation is associated with a number of problems which originate from a variety of clinical phenotypes and morphological forms, on the one hand, and from the rising prevalence of their latent course, on the other. In its turn, an adequate treatment choice may be based on understanding and accurate detection of etiological and morphological types of the disease. In this connection, development of novel diagnostic techniques, such as optical coherence tomography (OCT, is of utmost importance. Aim: To demonstrate feasibility of OCT in detection of morphological abnormalities associated with chronic inflammatory disorders of various localizations. Materials and methods: OCT diagnostics was performed in addition to standard diagnostic procedures in 225 patients with chronic inflammatory disorders of various localizations, such as chronic recurrent rhinitis, chronic latent salpingitis and chronic endometritis. For OCT, an “OCT-1300U” system was used, with central wavelength of 1280 nm, spatial resolution of 15–20 μm, image acquisition rate of 8 frames per second, imaging depth of 1.4 mm and a probe diameter of 2.4 mm. The following techniques of quantitative processing were used for processing of the OCT images. Quantitative characterization of histograms and image texture was performed with further determination of values typical for various images groups corresponding to particular states of biological tissues. Neural network was also employed with histograms and 2D Fourier transforms of the images as input data. Results: OCT laparoscopy allowed to obtain three types of OCT images of fallopian

Full Text Available Introduction: Due to the growing economical and ethical limitations in surgeons training for minimally invasive surgery (mis, e.g. laparoscopy, this study aims at evaluating the effect of a continuous practice of a particular videogame on the development of the fundamental and specific skills needed to perform this type of procedure successfully. Materials and methods: To evaluate the effectiveness of video game practicing, three essential and common activities were chosen (cutting, suturing, and eye-hand coordination to be performed in laparoscopic simulators. Eight different indexes or variables of performance were measured in the three activities. Fourteen voluntaries without previous experience in surgery were divided in two groups (intervention and control and their performance was evaluated before and after a one-month standardized training program with the video game Marble Mania®. Results: A general improvement of all the performance variables was observed after one month training in the intervention group. This improvement was significant with respect to the control group in three of the eight variables: suturing errors (p = 0.003, and the execution and number of errors in the eye-hand coordination (p = 0.025 and 0.001, respectively.

2014-04-01

Full Text Available Multiple shunt failure is a challenge in pediatric neurosurgery practice and one of the most feared complications of hydrocephalus. Objective: To demonstrate that laparoscopic procedures for distal ventriculoperitoneal shunt failure may be an effective option for patients who underwent multiple revisions due to repetitive manipulation of the peritoneal cavity, abdominal pseudocyst, peritonitis or other situations leading to a “non reliable” peritoneum. Method: From March 2012 to February 2013, the authors reviewed retrospectively the charts of six patients born and followed up at our institution, which presented with previous intra-peritoneal complications and underwent ventriculoperitoneal shunt revision assisted by video laparoscopy. Results: After a mean follow-up period of nine months, all patients are well and no further shunt failure was identified so far. Conclusion: Laparoscopy assisted shunt revision in children may be, in selected cases, an effective option for patients with multiple peritoneal complications due to ventriculo-peritoneal shunting.

2008-01-01

Full Text Available The aim of this study was to compare the hemodynamic and ventilatory effects of prolonged infrarenal aortic cross-clamping in pigs undergoing either laparotomy or laparoscopy. 18 pigs were used for this study. Infrarenal aortic crossclamping was performed for 60 minutes in groups I (laparotomy, n=6 and II (laparoscopy, n=6. Group III (laparoscopy, n=6 underwent a 120-minute long pneumoperitoneum in absence of aortic clamping (sham group. Ventilatory and hemodynamic parameters and renal function were serially determined in all groups. A significant decrease in pH and significant increase in PaCO2 were observed in group II, whereas no changes in these parameters were seen in group I and III. All variables returned to values similar to baseline in groups I and II 60 minutes after declamping. A significant increase in renal resistive index was evidenced during laparoscopy, with significantly higher values seen in Group II. Thus a synergic effect of pneumoperitoneum and aortic cross-clamping was seen in this study. These two factors together cause decreased renal perfusion and acidosis, thus negatively affecting the patient's general state during this type of surgery.

To investigate the use and success rate of hysteroscopic tubal electrocoagulation for the treatment of hydrosalpinx-related infertility among patients undergoing in vitro fertilization (IVF) who have laparoscopic contraindications. A prospective study was conducted among patients who had unilateral or bilateral hydrosalpinges identified on hysterosalpingography and vaginal ultrasonography, and who were undergoing IVF at a center in Cairo, Egypt, between January 1, 2013, and October 30, 2014. All patients who had contraindications for laparoscopy were scheduled for hysteroscopic tubal electrocoagulation (group 1); the other patients underwent laparoscopic tubal ligation (group 2). For all patients, hysterosalpingography was performed 3 months after their procedure to evaluate proximal tubal occlusion. Among 85 enrolled patients, 22 underwent hysteroscopic tubal electrocoagulation and 63 underwent laparoscopic tubal ligation. The procedure was successful in terms of tubal occlusion for 25 (93%) of 27 hydrosalpinges in group 1, and 78 (96%) of 81 hydrosalpinges in group 2 (P=0.597). No intraoperative or postoperative complications were reported. Hysteroscopic tubal electrocoagulation was found to be a successful treatment for hydrosalpinges before IVF when laparoscopy is contraindicated.

Ghasemi TA

2013-10-01

Full Text Available Introduction: Diagnostic errors have a natural complexity. Medical diagnoses make up a large proportion of all medical errors and cause much suffering and harm. Compared to other types of error, diagnostic errors receive little attention-a major factor in continuity of unacceptable rates of diagnostic error. Case: A 55-year-old woman presented to the emergency department (ED complaining of bone pain which has been started a month ago and increased gradually in the upper right thigh. Following the emergency evaluation she was sent home with pain medication. On the second visit, a femur neck fracture was seen in the x-ray. She underwent hemiarthroplasty and was discharged. Over several weeks she was reevaluated by many Physicians, because of her worsening pain .In the third visit after the surgery, her x-ray showed bone destruction and following bone biopsy, malignant paraganglioma was diagnosed. Discussion and solution: In all cases in which patient comes to us with skeletal pain, getting a comprehensive history and a full physical examination are prior to lab tests and x-rays. Bone metastasis which can develop severe pain and pathological fractures, is common in patients with malignant paraganglioma. Effective steps for diagnostic error prevention are: Considering the diagnostic error in the normal range of quality assurance surveillance and review, identifying the elements leading to diagnostic errors and getting feedback on the diagnoses Physicians make, in order to improve their skills. Conclusion: It is an every health system priority to identify, analyze, and prevent diagnostic errors in order to improve patient safety

The use of genome-wide tests to provide molecular diagnosis for individuals with autism spectrum disorder (ASD) requires more study. To perform chromosomal microarray analysis (CMA) and whole-exome sequencing (WES) in a heterogeneous group of children with ASD to determine the molecular diagnostic yield of these tests in a sample typical of a developmental pediatric clinic. The sample consisted of 258 consecutively ascertained unrelated children with ASD who underwent detailed assessments to define morphology scores based on the presence of major congenital abnormalities and minor physical anomalies. The children were recruited between 2008 and 2013 in Newfoundland and Labrador, Canada. The probands were stratified into 3 groups of increasing morphological severity: essential, equivocal, and complex (scores of 0-3, 4-5, and ≥6). All probands underwent CMA, with WES performed for 95 proband-parent trios. The overall molecular diagnostic yield for CMA and WES in a population-based ASD sample stratified in 3 phenotypic groups. Of 258 probands, 24 (9.3%, 95%CI, 6.1%-13.5%) received a molecular diagnosis from CMA and 8 of 95 (8.4%, 95%CI, 3.7%-15.9%) from WES. The yields were statistically different between the morphological groups. Among the children who underwent both CMA and WES testing, the estimated proportion with an identifiable genetic etiology was 15.8% (95%CI, 9.1%-24.7%; 15/95 children). This included 2 children who received molecular diagnoses from both tests. The combined yield was significantly higher in the complex group when compared with the essential group (pairwise comparison, P = .002). [table: see text]. Among a heterogeneous sample of children with ASD, the molecular diagnostic yields of CMA and WES were comparable, and the combined molecular diagnostic yield was higher in children with more complex morphological phenotypes in comparison with the children in the essential category. If replicated in additional populations, these findings may

Laparoscopy may prove feasible to address surgical needs in limited-resource settings. However, no aggregate data exist regarding the role of laparoscopy in low- and middle-income countries (LMICs). This study was designed to describe the issues facing laparoscopy in LMICs and to aggregate reported solutions. A search was conducted using Medline, African Index Medicus, the Directory of Open Access Journals, and the LILACS/BIREME/SCIELO database. Included studies were in English, published after 1992, and reported safety, cost, or outcomes of laparoscopy in LMICs. Studies pertaining to arthroscopy, ENT, flexible endoscopy, hysteroscopy, cystoscopy, computer-assisted surgery, pediatrics, transplantation, and bariatrics were excluded. Qualitative synthesis was performed by extracting results that fell into three categories: advantages of, challenges to, and adaptations made to implement laparoscopy in LMICs. PRISMA guidelines for systematic reviews were followed. A total of 1101 abstracts were reviewed, and 58 articles were included describing laparoscopy in 25 LMICs. Laparoscopy is particularly advantageous in LMICs, where there is often poor sanitation, limited diagnostic imaging, fewer hospital beds, higher rates of hemorrhage, rising rates of trauma, and single income households. Lack of trained personnel and equipment were frequently cited challenges. Adaptive strategies included mechanical insufflation with room air, syringe suction, homemade endoloops, hand-assisted techniques, extracorporeal knot tying, innovative use of cheaper instruments, and reuse of disposable instruments. Inexpensive laboratory-based trainers and telemedicine are effective for training. LMICs face many surgical challenges that require innovation. Laparoscopic surgery may be safe, effective, feasible, and cost-effective in LMICs, although it often remains limited in its accessibility, acceptability, and quality. This study may not capture articles written in languages other than

Evidence regarding drug provocation test (DPT) with antineoplastic and biological agents is scarce. Our aim was to assess the usefulness of including DPT as a paramount gold standard diagnostic tool (prior to desensitization). Prospective, observational, longitudinal study with patients who, during a 3-year period, were referred to the Desensitization Program at Ramon y Cajal University Hospital. Patients underwent a structured diagnostic protocol by means of anamnesis, skin tests (ST), risk assessment, and DPT. Oxaliplatin-specific IgE was determined in oxaliplatin-reactive patients (who underwent DPT regardless of oxaliplatin-specific IgE results). Univariate analysis and multivariate analysis were used to identify predictors of the final diagnosis among several variables. A total of 186 patients were assessed. A total of 104 (56%) patients underwent DPT. Sixty-four percent of all DPTs were negative (i.e., hypersensitivity was excluded). Sensitivity for oxaliplatin-specific IgE (0.35 UI/l cutoff point) was 34%, specificity 90.3%, negative predictive value 45.9%, positive predictive value 85%, negative likelihood ratio 0.7, and positive likelihood ratio 3.5. These are the first reported data based on more than 100 DPTs with antineoplastic and biological agents (paclitaxel, oxaliplatin, rituximab, infliximab, irinotecan, and other drugs). Implementation of DPT in diagnostic protocols helps exclude hypersensitivity (in 36% of all referred patients), and avoids unnecessary desensitizations in nonhypersensitive patients (30-56% of patients, depending on culprit-drug). Drug provocation test is vital to validate diagnostic tools; consequently, quality data are shown on oxaliplatin-specific IgE and oxaliplatin-ST in the largest series of oxaliplatin-reactive patients reported to date (74 oxaliplatin-reactive patients). Identifying phenotypes and predictors of a diagnosis of hypersensitivity may be helpful for tailored plans. © 2015 John Wiley & Sons A/S. Published by

Full Text Available Postoperative nausea and vomiting (PONV are still a significant problem in modern anesthetic practice. Discomfort caused by PONV intensifies other unpleasant elements of recovery, such as pain, frustration or fear. PONV also generates aversion to future anesthesia and have a negative impact on staff and patient's family. PONV can increase the cost of completing a surgical procedure, because it extends the time a patient spends in the postanesthesia care unit (PACU or delay discharge of ambulatory patients. It is generally accepted that the incidence of PONV after general anesthesia for various types of surgery in the last decade is still between 20-30%, and 70% in laparoscopic abdominal surgery. The incidence is three times higher in females compared to males. Many factors are involved in triggering PONV, such as patientrelated factors, the type of surgery, anesthesia management, etc. The results of this study suggest that the patient positioning (modified supine lithotomy position with ''Trendelenburg" increases the risk of PONV in gynecologic laparoscopy.

Omental cystic lymphangioma is an extremely rare abdominal mass caused by congenital malformation. An 8-year-old premenarchal girl reported abdominal pain. Diagnostic imaging revealed a large multicystic mass measuring 22 cm in diameter, which occupied the entire abdominal cavity with ascites. Emergency laparoscopy revealed a ruptured large cystic mass originating from the greater omentum; this was followed by successful laparoscopic-assisted excision. The pathological diagnosis was omental cystic lymphangioma. The present findings show that omental cystic lymphangioma masquerading as mucinous ovarian neoplasia was a rare cause of acute abdominal events in a young girl. The present case shows that minimally invasive surgery can be a feasible option, which might achieve a favorable outcome in a young patient with an omental cystic lymphangioma.

Most investigators agree that endometriosis is associated with a state of subclinical, non-infectious peritoneal inflammation. The objective of the study was to assess concentrations of two markers of the acute inflammatory phase proteins, haptoglobin and ceruloplasmin, in peritoneal fluid of endometriotic women. 229 women who underwent diagnostic or therapeutic laparoscopy were included in the study Minimal, mild, moderate and severe endometriosis according to ASRM was confirmed in 119 women (study groups), whereas 110 patients suffered from simple serous or dermoid ovarian cysts (reference groups). Haptoglobin and ceruloplasmin concentrations in the peritoneal fluid samples aspirated during laparoscopy were measured using commercially available radial immunodiffusion kits. The concentration of haptoglobin in the peritoneal fluid of women with endometriosis was significantly higher as compared to patients with serous and dermoid ovarian cysts. Significantly higher haptoglobin level was observed in patients with severe and moderate endometriosis as compared to women from both reference groups. No significant difference in the peritoneal fluid ceruloplasmin levels was found between patients with endometriosis and women from reference groups. However, it was noted that ceruloplasmin levels are higher in the subgroup of patients with severe endometriosis as compared to both reference groups and women with mild disease. Our results support the hypothesis that endometriosis is associated with subclinical inflammation within the peritoneal cavity It may be speculated that pro-inflammatory stimuli strong enough to cause an increase in acute inflammatory phase proteins peritoneal fluid concentrations are observed only in the advanced stages of the disease.

Minimally invasive surgery requires technical skills distinct from those used in conventional surgery. The aim of this prospective study was to identify personal characteristics that may predict the attainable proficiency level of first-time virtual reality laparoscopy (VRL) trainees. Two hundred and seventy-nine consecutive undergraduate medical students without experience attended a standardized VRL training. Performance data of an abstract and a procedural task were correlated with possible predictive factors providing potential competence in VRL. Median global score requirement status was 86.7% (interquartile range (IQR) 75-93) for the abstract task and 74.4% (IQR 67-88) for the procedural task. Unadjusted analysis showed significant increase in the global score in both tasks for trainees who had a gaming console at home and frequently used it as well as for trainees who felt self-confident to assist in a laparoscopic operation. Multiple logistic regression analysis identified frequency of video gaming (often/frequently vs. rarely/not at all, odds ratio: abstract model 2.1 (95% confidence interval 1.2; 3.6), P = 0.009; virtual reality operation procedure 2.4 (95% confidence interval 1.3; 4.2), P = 0.003) as a predictive factor for VRL performance. Frequency of video gaming is associated with quality of first-time VRL performance. Video game experience may be used as trainee selection criteria for tailored concepts of VRL training programs.

Confocal microscopy was used as an additional diagnostic method in several patients (Confoscan-4, Nidek.Results: Pseudoexfoliation material was found at the pupillary margin in 64.8% of patients, and on the lens capsule (central disc in 71% of the test subjects. Peripheral depositions were present in almost all PES patients under mydriasis. Pupil dilation has been allowed to establish the diagnosis of PES additionally in 16% of patients. At the «mini-PES»-stage PES material was most frequently found in the superior-nasal quadrant of lens capsule (85.6%. Clinical asymmetry of several signs (pupil diameter, anterior chamber angle pigmentation, IOP level should be taken into consideration in early PES diagnostics.Conclusion: Examination under mydriasis and knowledge of PES micro-signs in some cases has been allowed to suspect PESeven at the preclinical stage.

Full Text Available BACKGROUND: Atherosclerosis is the main cause of peripheral artery occlusive disease (PAOD of the lower limbs. Patients with PAOD often also have obstructive atherosclerosis in other arterial sites, mainly the coronary arteries. This means that patients who undergo infrainguinal bypass to treat critical ischemia have a higher risk of AMI. There are, however, few reports in the literature that have assessed this risk properly. OBJECTIVE: The aim of this study was to determine the incidence of acute myocardial infarction in patients who underwent infrainguinal bypass to treat critical ischemia of the lower limbs caused by PAOD. MATERIAL AND METHODS: A total of 64 patients who underwent 82 infrainguinal bypass operations, from February 2011 to July 2012 were studied. All patients had electrocardiograms and troponin I blood assays during the postoperative period (within 72 hours. RESULTS: There were abnormal ECG findings and elevated blood troponin I levels suggestive of AMI in five (6% of the 82 operations performed. All five had conventional surgery. The incidence of AMI as a proportion of the 52 conventional surgery cases was 9.6%. Two patients died. CONCLUSION: There was a 6% AMI incidence among patients who underwent infrainguinal bypass due to PAOD. Considering only cases operated using conventional surgery, the incidence of AMI was 9.6%.

Measuring the diagnostic accuracy (DA) of an EEG device is unconventional and complicated by imperfect interrater reliability. We sought to compare the DA of a miniature, wireless, battery-powered EEG device (“microEEG”) to a reference EEG machine in emergency department (ED) patients with altered mental status (AMS). 225 ED patients with AMS underwent 3 EEGs. EEG1 (Nicolet Monitor, “reference”) and EEG2 (microEEG) were recorded simultaneously with EEG cup electrodes using a signal splitter. ...

Vaginal Cuff Dehiscence Presenting with Free Air 60 Days after Robotic-Assisted Hysterectomy

2017-01-01

Full Text Available Introduction. The vast majority of patients presenting with pneumoperitoneum have visceral organ perforation and require urgent diagnostic laparoscopy. Nonsurgical causes are relatively rare and may be attributed to multiple etiologies. Case Presentation. Here we describe the case of a 38-year-old Caucasian female who presented to the emergency department with three days of cramping, epigastric abdominal pain. Her physical exam was notable for tenderness to palpation in the epigastric area and abdominal and chest X-rays showed free air under the diaphragm. Free air around the porta hepatis was verified on CT scan. Approximately 90% of pneumoperitoneum cases are due to perforation of visceral organs and therefore require operative management. An urgent exploratory laparoscopy revealed no clear source of free air, but postoperatively the patient developed a large volume of watery discharge from her vagina. Subsequent workup revealed a 1 cm vaginal cuff dehiscence which was later repaired with no postoperative complications. Conclusion. Although the majority of patients with pneumoperitoneum require urgent exploratory laparoscopy, a careful diagnostic workup may reveal sources of free air that are not related to hollow viscous perforation. Vaginal cuff dehiscence represents a rare yet nonurgent source of pneumoperitoneum. This differential should be considered in light of the possible intra- and postoperative complications of surgery.

Current less invasive surgical techniques, the use of new analgesic and anesthetic drugs, and early mobilization ("multimodal surgical strategies") reduce the occurrence of post-surgery paralytic ileus and vomiting, making possible early nutrition by the digestive route. With these premises, a nutrition protocol was designed for its implementation in colorectal pathology susceptible of laparoscopy-assisted surgery. to assess the efficacy of this protocol that comprises 3 phases. Phase I: home preparation with 7 days duration; low-residues and insoluble fiber diet, supplemented with 400 mL of hyperproteic polymeric formula with no lactose or fiber, bowel cleansing 2 days prior to surgery and hydration with water, sugared infusions, and vegetable broth. Phase II: immediate post-surgical period with watery diet for 3 days with polymeric diet with no fiber. Phase III: semi-solid diet with no residues, nutritional formula and progressive reintroduction of food intake in four stages of varying duration according to surgery and digestive tolerance. prospective study performed at our hospital with patients from our influence area, from February 2003 to May 2004, including 25 patients, 19 men and 6 women, with mean age of 63.3 years (range = 33-79) and mean body mass index of 26.25 kg/m2 (range = 20.84-31.3), all of them suffering from colorectal pathology susceptible of laparoscopy-assisted surgery, and to which the study protocol was applied. Fourteen left hemicolectomies, 5 right hemicolectomies, 4 low anterior resections with protective colostomy, and subtotal colectomies and lateral ileostomy were done. Final diagnoses were: 3 diverticular diseases; 3 adenomas; 7 rectosigmoidal neoplasms; and 12 large bowel neoplasms in other locations. The pathology study confirmed: pT3N0 (n = 7), pT3N1 (n = 3), pT3N2 (n = 1), and pT3N1M1 (n = 1), pT1N0 (n = 4), pT1N1 (n = 2), pTis (n = 1).

2016-12-01

High-resolution manometry (HRM) is the gold-standard diagnostic tool for achalasia of the esophagus. Laparoscopic Heller-Dor technique is the preferred surgical approach with success rate estimated 90%. The use of intraoperative HRM provides real-time estimation of intraluminal esophageal pressures and identifies the exact points of esophageal luminal pressure during laparoscopy. Ten patients with achalasia underwent surgery. All patients preoperatively completed 1 manometric study and Quality of Life questionnaires (EORTC QLQ-C30 version 3.0) with Eckardt scores. We collected intraoperative manometry data and repeated manometric studies, EORTC QLQ-C30, and Eckardt scores postoperatively. Median Eckardt score was decreased from 7.5 to 0.5, mean resting pressure decreased from 51.4 to 11.9 mm Hg, whereas mean residual pressure diminished from 45.9 to 9.5 mm Hg postoperatively. The simultaneous use of HRM during the Heller-Dor technique may lead to an individualized management of the disease.

Background: Hematopoietic stem cell transplantation (SCT) can be complicated by a variety of live-threatening infectious and non-infectious pulmonary complications. The management of these complications is critically dependent on the most probable diagnosis, which is in part based on imaging work-up. Methods: Systematic review of the literature related to the diagnostic value of high-resolution computed tomography (HRCT) in patients who underwent SCT and developed respiratory symptoms. Results: Literature review did not reveal systematic cohort studies that included patients with respiratory symptoms post-SCT who underwent HRCT and had a well-defined outcome. Most studies selected participants based on their final diagnosis instead of the indication for diagnostic testing in practice. Nevertheless, several papers clearly indicated a potential role for HRCT when complications after SCT occur. A variety of articles described the role of certain HRCT findings in the diagnosis of specific infectious complications, but less data were available for non-infectious complications. Conclusion: We believe more diagnostic studies are needed to determine the value of HRCT for a specific diagnosis in SCT-recipients who present with respiratory symptoms at the transplant clinic. Currently, radiologists should be cautious since HRCT interpretation in these patients is not unambiguous.

A perforated peptic ulcer can be managed laparoscopically in selected patients. The purpose of this study was to evaluate whether conversion of emergency laparoscopy is inferior to primary median laparotomy in terms of postoperative morbidity and mortality. We analyzed patients who underwent laparoscopic or open surgery for a perforated peptic ulcer at the Department of Surgery, University of Schleswig-Holstein, Campus Luebeck between January, 1996 and December, 2010. Perforations were graded according to the Boey classification, a preoperative risk-scoring system. Conversion to laparotomy was necessary in 20 of the 45 patients who underwent laparoscopic surgery (CG); therefore, laparoscopic operations were completed in 25 patients (LG). The third patient cohort comprised 139 patients who underwent primary laparotomy (OG). Overall minor morbidity was significantly lower (p = 0.048) in the LG patients than in the OG patients, whereas no significant differences were found in major morbidity and mortality, particularly between the OG and CG. Patients' suitability for laparoscopic management should be decided on according to Boey's clinical scoring system. Our findings demonstrated that conversion from laparoscopy to laparotomy was not associated with elevated postoperative morbidity or mortality versus initial laparotomy. Therefore, emergency operations may be commenced laparoscopically in selected patients, especially considering the postoperative advantages of this approach.

We sought to compare robotic vs laparoscopic surgery in regards to patient reported postoperative pain and quality of life. This was a prospective study of patients who presented for treatment of a new gynecologic disease requiring minimally invasive surgical intervention. All subjects were asked to take the validated Brief Pain Inventory-Short Form at 3 time points to assess pain and its effect on quality of life. Statistical analyses were performed using Pearson x(2) and Student's t test. One hundred eleven were included in the analysis of which 56 patients underwent robotic assisted surgery and 55 patients underwent laparoscopic surgery. There was no difference in postoperative pain between conventional laparoscopy and robotic assisted surgery for gynecologic procedures. There was a statistically significant difference found at the delayed postoperative period when evaluating interference of sleep, favoring laparoscopy (ROB 2.0 vs LSC 1.0; P = .03). There were no differences found between the robotic and laparoscopic groups of patients receiving narcotics (56 vs 53, P = .24, respectively), route of administration of narcotics (47 vs 45, P > .99, respectively), or administration of nonsteroidal antiinflammatory medications (27 vs 21, P = .33, respectively). Our results demonstrate no difference in postoperative pain between conventional laparoscopy and robotic assisted surgery for gynecologic procedures. Furthermore, pain did not appear to interfere consistently with any daily activity of living. Interference of sleep needs to be further evaluated after controlling for bilateral salpingo-oophorectomy. Copyright © 2015 Elsevier Inc. All rights reserved.

To evaluate diagnostic imaging costs before and after DTS implementation in patients with suspected thoracic lesions on CXR. Four hundred sixty-five patients (263 male, 202 female; age, 72.47 ± 11.33 years) with suspected thoracic lesion(s) after CXR underwent DTS. Each patient underwent CT when a pulmonary non-calcified lesion was identified by DTS while CT was not performed when a benign pulmonary or extrapulmonary lesion or pseudolesion was identified. The average per-patient imaging cost was calculated by normalising the costs before and after DTS implementation. In 229/465 patients who underwent DTS after suspicious CXR, DTS showed 193 pulmonary lesions and 36 pleural lesions, while in the remaining 236/465 patients, lesions were ruled out as pseudolesions of CXR. Chest CT examination was performed in 127/465 (27 %) patients while in the remaining 338/465 patients (73 %) CXR doubtful findings were resolved by DTS. The average per-patient costs of CXR, DTS and CT were 15.15, 41.55 and 113.66. DTS allowed an annual cost saving of 8,090.2 considering unenhanced CT and 19,298.12 considering contrast-enhanced CT. Considering a DTS reimbursement rate of 62.7 the break even point corresponds to 479 DTS examinations. Per-patient diagnostic imaging costs decreased after DTS implementation in patients with suspected thoracic lesions. • Digital tomosynthesis improves the diagnostic accuracy and confidence in chest radiography • Digital tomosynthesis reduces the need for CT for a suspected pulmonary lesion • Digital tomosynthesis requires a dose level equivalent to that of around two chest radiographies • Digital tomosynthesis produces a significant per-patient saving in diagnostic imaging costs.

Minimal and mild endometriosis (stage 1 and 2 AFSR) can lead to chronic pelvic pain and infertility but can also exist in asymptomatic patients. The prevalence of asymptomatic patients with minimal and mild endometriosis is not clear but typical endometriosis lesions are found in about 5 to 10% of asymptomatic women and more than 50% of painful and/or infertile women. Laparoscopic treatment of minimal and mild endometriotic lesions is justified in case of pelvic pain because their destruction decrease significatively the pain compared with diagnostic laparoscopy alone. In this context, ablation and excision give identical results in terms of pain reduction. Moreover, literature shows no interest in uterine nerve ablation in case of dysmenorrhea due to minimal and mild endometriosis. Then, it is recommended to treat these lesions during a laparoscopy realised as part of pelvic pain. On the other hand, it is not recommended to treat asymptomatic patients. With regard to treatment of minimal and mild endometriosis in infertile patients, only two studies can be selected and both show that laparoscopy with excision or ablation and ablation of adhesions is superior to diagnostic laparoscopy alone in terms of pregnancy rate. However, it is not recommended to treat these lesions when they are asymptomatic because there is no evidence that they can progress with symptomatic disease. There is no study assessing the interest to treat these lesions when they are found fortuitously. Adhesion barrier utilisation permits to reduce post-operative adhesions, however literature failed to demonstrate the clinical profit in terms of reduction of the risk of pain or infertility.

Full Text Available Abstract Objective: The present study investigated effect of using pump on postoperative pleural effusion in patients who underwent coronary artery bypass grafting. Methods: A total of 256 patients who underwent isolated coronary artery bypass grafting surgery in the Cardiovascular Surgery clinic were enrolled in the study. Jostra-Cobe (Model 043213 105, VLC 865, Sweden heart-lung machine was used in on-pump coronary artery bypass grafting. Off-pump coronary artery bypass grafting was performed using Octopus and Starfish. Proximal anastomoses to the aorta in both on-pump and off-pump techniques were performed by side clamps. The patients were discharged from the hospital between postoperative day 6 and day 11. Results: The incidence of postoperative right pleural effusion and bilateral pleural effusion was found to be higher as a count in Group 1 (on-pump as compared to Group 2 (off-pump. But the difference was not statistically significant [P>0.05 for right pleural effusion (P=0.893, P>0.05 for bilateral pleural effusion (P=0.780]. Left pleural effusion was encountered to be lower in Group 2 (off-pump. The difference was found to be statistically significant (P<0.05, P=0.006. Conclusion: Under the light of these results, it can be said that left pleural effusion is less prevalent in the patients that underwent off-pump coronary artery bypass grafting when compared to the patients that underwent on-pump coronary artery bypass grafting.

Pinpointing the location of accessory conduction pathway (ACP) is of great importance in the surgical treatment for Wolff-Parkinson-White (WPW) syndrome. For this purpose, this study explored the usefulness of ECG-gated emission computed tomography (Gated-ECT) in 30 patients who preoperatively underwent Gated-ECT. The site of earliest contraction at level of atrioventicular valves, obtained on tomographic phase analysis, was compared with the site of earliest activation, obtained on epicardial mapping during surgery. The concordance rate of the two methods was 94 % (28/30). Among them, one patient was found to have the association of corrected transposition of great arteries on Gated-ECT. Gated-ECT was, however, of limited value in differentiating right posterior ACP from right postseptal ACP. The discordance between the sites of earliest contraction and activation, which was observed in the two others, was likely due to decreased wall motion resulting from myocardial disturbance. Gated-ECT may have a diagnostic potential for the location of ACP, especially in view of providing images that corresponded to the surgical anatomy. (Namekawa, K.).

The diagnostic value of C-reactive protein (CRP) level for pneumonia in children is unknown. As a first step in the assessment of the value of CRP, a diagnostic study was performed in children at an emergency department (ED). In this cross-sectional study, data were retrospectively collected from children presenting with suspected pneumonia at the ED of Antonius Hospital Nieuwegein in The Netherlands between January 2007 and January 2012. Diagnostic outcome was pneumonia yes/no according to independent radiologist. (Un)adjusted association between CRP level and pneumonia and diagnostic value of CRP were calculated. Of 687 presenting children, 286 underwent both CRP measurement and chest radiography. 148 had pneumonia (52%). The proportion of pneumonia increased with CRP level. Negative predictive values declined, but positive predictive values increased with higher CRP thresholds. Univariable odds ratio for the association between CRP level and pneumonia was 1.2 (95% CI 1.11-1.21) per 10 mg/L increase. After adjustment for baseline characteristics CRP level remained associated with pneumonia. CRP level has independent diagnostic value for pneumonia in children presenting at the ED with suspected pneumonia, but low levels do not exclude pneumonia in this setting. These results prompt evaluation of CRP in primary care children with LRTI. Copyright © 2013 Elsevier Ltd. All rights reserved.

The aim of this study was to compare in patients presenting with acute chest pain the clinical outcomes and cost-effectiveness of an accelerated diagnostic protocol utilizing contemporary technology in a chest pain unit versus routine care in an internal medicine department. Hospital and 90-day course were prospectively studied in 585 consecutive low-moderate risk acute chest pain patients, of whom 304 were investigated in a designated chest pain center using a pre-specified accelerated diagnostic protocol, while 281 underwent routine care in an internal medicine ward. Hospitalization was longer in the routine care compared with the accelerated diagnostic protocol group (pdiagnostic protocol patients (98%) vs. 57 (20%) routine care patients underwent non-invasive testing, (pdiagnostic imaging testing was performed in 125 (44%) and 26 (9%) patients in the routine care and accelerated diagnostic protocol patients, respectively (pdiagnostic protocol patients compared with those receiving routine care was associated with a lower incidence of readmissions for chest pain [8 (3%) vs. 24 (9%), pdiagnostic protocol remained a predictor of lower acute coronary syndromes and readmissions after propensity score analysis [OR = 0.28 (CI 95% 0.14-0.59)]. Cost per patient was similar in both groups [($2510 vs. $2703 for the accelerated diagnostic protocol and routine care group, respectively, (p = 0.9)]. An accelerated diagnostic protocol is clinically superior and as cost effective as routine in acute chest pain patients, and may save time and resources.

To determine the diagnostic accuracy and frequency of complications of fluoroscopyguided transthoracic needle biopsy, using an automated gun biopsy system. We retrospectively reviewed 86 patients who underwent automated gun biopsy between October 1995 and October 1996. An 18-gauge cutting needle was used in all cases. All biopsies were performed under fluoroscopic guidance by one interventional radiologist. Tissue sufficient for histologic diagnosis was obtained in 73 of 86 biopsies(84.9%). Fifty-six lesions were malignent and 30 were benign. Sensitivity and diagnostic accuracy for malignant lesions were 87.5% and 87.5%, respectively while cell type specificity in malignant diagnosis was 91.7%(11/12). Sensitivity and diagnostic accuracy for benign lesions were 80.0% and 73.3%, respectively. Postbioptic pneumothorax occurred in three of 86 biopsies(3.5%), one of which required placement of a chest tube. Automated gun biopsy is a simple, safe method for the diagnosis of focal chest lesions. An automated biopsy device offers high diagnostic accuracy in casis involving malignant and benign lesions of the chest, and is particularly useful for determining malignant cell type and specific diagnosis of benign lesions.=20

Purpose: Evaluation of diagnostic accuracy of preoperative fine needle aspiration cytology (FNAC) in salivary gland lesions. Patients and Methods: This is a retrospective study of 82 patients presented at NCI, Cairo University with salivary gland lesion who underwent preoperative FNAC diagnosis with subsequent excision and histopathologic assessment. Cytology results were classified as negative, positive, suspicious for cancer and inadequate. The definitive histopathologic report according to WHO Histological typing was the gold standard diagnosis against which FNAC was compared. Results: Our study included 82 patients who underwent preoperative FNAC of major salivary glands with subsequent surgical excision. Male to female ratio was 1.4: 1. The median age was 42 years. Parotid gland was involved in (68.3%), submandibular in (28%) and sub mental gland in (3.7%). Forty cases (48.8%) were cytologically diagnosed as benign lesions, 26 (31.7%) were malignant and 10 (12.2%) were suspicious. Cytological findings were non diagnostic in 6 (7.3%). The most common benign cytologic diagnosis was pleomorphic adenoma; 16 out of 40 cases (40%), while the most common malignant tumor was carcinoma; 22 out of 26 cases (84.6%). Cytologic diagnoses were compared with histopathologic ones and were true-negative in 37 (92.5%), true-positive in 33 (91.6%), false-negative in 3 (8.3%) and false-positive in 3 (7.5%) cases regarding detection of malignant tumors. The cytologic diagnosis achieved a sensitivity of 91.7%; a specificity of 92.5%, PPV 91.6%, NPV 92.5% and diagnostic accuracy 92%. The rates of agreement of histopathologic type for benign and malignant tumors were 89.2% and 91%, respectively. Conclusion: The sensitivity, specificity and diagnostic accuracy of FNAC were 91.7%, 92.5% and 92%, respectively. Attention to subtle morphologic changes, pitfalls and limitations are important to increase diagnostic accuracy. Multidirectional aspiration is preferred to avoid selective

Conclusion: Symptomatic gallbladder disease in the setting of peritoneal carcinomatosis secondary to invasive lobular carcinoma is an uncommon presentation to surgeons. A diagnostic laparoscopy is the preferred initial evaluation. If deemed feasible, and if the surgeon has the required experience, a laparoscopic cholecystectomy can be undertaken selectively.

Full Text Available We evaluated 752 patients for endometriosis in consecutive laparoscopic procedures over a one year period. Six hundred eighty patients underwent laparoscopy for indications unrelated to symptoms of endometriosis and 72 patients were diagnosed clinically to have endometriosis before the procedures. In the 72 patients with clinical indications of endometriosis, 59 patients had disease confirmed at surgery (82%. Out of 680 asymptomatic patients, 186 patients (24.7% were documented to have the disease of various characteristics or appearances in which the typical lesions accounted for 42%. The overall prevalence among these women undergoing laparoscopy was 32.5%. However, a prevalence of 12% was shown in a subset of asymptomatic patients indicated for sterilization. This may reflect the appropriate prevalence in reproductive age population.

To compare the diagnostic yield of whole-body post-mortem computed tomography (PMCT) imaging to post-mortem magnetic resonance (PMMR) imaging in a prospective study of fetuses and children. We compared PMCT and PMMR to conventional autopsy as the gold standard for the detection of (a) major pathological abnormalities related to the cause of death and (b) all diagnostic findings in five different body organ systems. Eighty two cases (53 fetuses and 29 children) underwent PMCT and PMMR prior to autopsy, at which 55 major abnormalities were identified. Significantly more PMCT than PMMR examinations were non-diagnostic (18/82 vs. 4/82; 21.9 % vs. 4.9 %, diff 17.1 % (95 % CI 6.7, 27.6; p < 0.05)). PMMR gave an accurate diagnosis in 24/55 (43.64 %; 95 % CI 31.37, 56.73 %) compared to 18/55 PMCT (32.73 %; 95 % CI 21.81, 45.90). PMCT was particularly poor in fetuses <24 weeks, with 28.6 % (8.1, 46.4 %) more non-diagnostic scans. Where both PMCT and PMMR were diagnostic, PMMR gave slightly higher diagnostic accuracy than PMCT (62.8 % vs. 59.4 %). Unenhanced PMCT has limited value in detection of major pathology primarily because of poor-quality, non-diagnostic fetal images. On this basis, PMMR should be the modality of choice for non-invasive PM imaging in fetuses and children. (orig.)

Full Text Available It is known that a large ovarian cyst will likely cause torsion. However, normal adnexal torsion is rare and occurs in premenarchal girls in most cases. This is a case of a reproductive woman. A 31-year-old woman suffering from acute abdominal pain in the lower and right side consulted her gynecologist. The next day she had a computed tomography performed and was suspected of ovarian torsion. She did not have fever, nausea, or leukocytosis, but her abdominal pain persisted. Diagnostic laparoscopy was performed and showed torsion of the right fallopian tube, which was swollen and looked like a hydrosalpinx with a normal ovary. We did detorsion and excision of the right tube. However, pathological findings showed that the right tube was not a hydrosalpinx but was swollen due to blood stasis. We determined that this case was torsion of normal adnexa. In such cases, diagnostic laparoscopy is very effective.

The aim of this study was to investigate a possible role for interleukin-6 (IL-6) and tumour necrosis factor (TNF-alpha) as pre-operative markers for the diagnosis of ovarian torsion. Twenty consecutive patients admitted to the gynaecological emergency room with suspected clinical diagnosis of ovarian torsion were prospectively assigned to the study. Blood samples were drawn pre-operatively and examined for serum concentrations of IL-6 and TNF-alpha. Surgeons were blinded to laboratory results prior to laparoscopy. The pre-operative diagnosis of ovarian torsion was confirmed during an urgent diagnostic laparoscopy in 8 (40%) patients. The surgical diagnosis among the remaining 12 patients was a large ovarian cyst not in torsion. In six out of eight (75.0%) patients with ovarian torsion serum IL-6 concentrations were elevated. None of the 12 patients without torsion had elevated serum IL-6 concentrations. This difference was statistically significant (P < 0.001). There was no significant difference in the proportion of women with elevated serum TNF-alpha concentrations, two of eight (25.0%) patients with torsion and four of 12 (33.3%) control cases. Elevated serum IL-6 concentrations, but not serum TNF-alpha concentrations, were significantly associated with the occurrence of ovarian torsion. In patients with vague clinical signs of ovarian torsion, serum IL-6 might help to distinguish which patients should undergo diagnostic laparoscopy.

Optimal use of whole-exome sequencing (WES) in the pediatric setting requires an understanding of who should be considered for testing and when it should be performed to maximize clinical utility and cost-effectiveness. To investigate the impact of WES in sequencing-naive children suspected of having a monogenic disorder and evaluate its cost-effectiveness if WES had been available at different time points in their diagnostic trajectory. This prospective study was part of the Melbourne Genomics Health Alliance demonstration project. At the ambulatory outpatient clinics of the Victorian Clinical Genetics Services at the Royal Children's Hospital, Melbourne, Australia, children older than 2 years suspected of having a monogenic disorder were prospectively recruited from May 1 through November 30, 2015, by clinical geneticists after referral from general and subspecialist pediatricians. All children had nondiagnostic microarrays and no prior single-gene or panel sequencing. All children underwent singleton WES with targeted phenotype-driven analysis. The study examined the clinical utility of a molecular diagnosis and the cost-effectiveness of alternative diagnostic trajectories, depending on timing of WES. Of 61 children originally assessed, 44 (21 [48%] male and 23 [52%] female) aged 2 to 18 years (mean age at initial presentation, 28 months; range, 0-121 months) were recruited, and a diagnosis was achieved in 23 (52%) by singleton WES. The diagnoses were unexpected in 8 of 23 (35%), and clinical management was altered in 6 of 23 (26%). The mean duration of the diagnostic odyssey was 6 years, with each child having a mean of 19 tests and 4 clinical genetics and 4 nongenetics specialist consultations, and 26 (59%) underwent a procedure while under general anesthetic for diagnostic purposes. Economic analyses of the diagnostic trajectory identified that WES performed at initial tertiary presentation resulted in an incremental cost savings of A$9020 (US$6838) per

Intestinal malrotations with midgut volvulus are surgical emergencies that can lead to life-threatening intestinal necrosis. This study evaluates the feasibility and the outcomes of laparoscopic treatment of midgut volvulus compared with classic open Ladd's procedure in neonates. The medical records of all neonates with diagnosis of malrotation and volvulus, who underwent surgery between January 1993 and January 2014, were reviewed. We considered the group of neonates laparoscopically treated (Group A, n = 20) and we compared it with an equal number of neonates treated with the classical open Ladd's procedure (Group B, n = 20). The median age at surgery was 8.4 days and the mean weight was 3.340 kg. The suspicion of volvulus was documented by plain abdominal radiograph, upper gastrointestinal contrast study, and/or ultrasound scanning of the mesenteric vessels. All the patients were treated according to the Ladd's procedure. Conversion to an open procedure was necessary in 25% of the patients. The mean operative time was 80 minutes (28-190 minutes) in Group A and 61 minutes (40-130 minutes) in Group B (P = .04). The median time to full diet (P = .02) and hospital stay (P = .04) was better in Group A. Rehospitalization because of recurrence of occlusive symptoms occurred in 30% of patients in Group A (n = 6) and in 40% of patients in Group B (n = 8). Among these, all the 6 patients of Group A underwent redo surgery for additional division of Ladd's bands or debridement; instead in Group B, 4 of 8 patients underwent open redo surgery. Laparoscopic exploration is the procedure of choice in case of suspicion of intestinal malrotation and volvulus. Laparoscopic treatment is feasible and safe even in neonatal age without additional risks compared with classical open Ladd's procedure.

Comparison of diagnostic quality in hysterosalpingography between low and high-osmolality contrast media. We performed a retrospective evaluation of two cohorts of patients who underwent HSG using contrast media with different osmolarity: the first group ,47 patients, underwent hysterosalpingography in the period September 2011-December 2012 using Iopromide 370 mg/ml; the second group, 50 patients, underwent HSG from January 2013 to October 2013 using Iomeprol 400 mg/ml. Three radiologists, in consensus reading,, reviewed the radiographs by assessing the following four parameters: opacification of the uterine cavity, uterine profiles definition, Fallopian tubes visualization, contrast media spillage into peritoneum. A score-scale from 0 to 3 was assigned for each of the mentioned parameter (0 = minimum non-diagnostic exam, 1 = sufficient examination; 2 = good quality examination; maximum 3 = high quality images). We documented a statistically significant higher quality in displaying Fallopian tubes among patients studied through high osmolarity contrast medium (Iopromide 370 mg/ml) than what obtained through lower osmolarity contrast medium (Iomeprol 400 mg/ml). The use of high osmolarity contrast medium enabled better visualization of the tubes and a greater number of diagnoses of chronic aspecific salpigintis due to the increased osmolality and viscosity of Iomeprol 400 mg/ml. There were no significant differences between the two contrast agents in the evaluation of intra-uterine pathology and in the evaluation of the tubal patency.

The purpose of this study was primarily to assess the diagnostic performance of magnetic resonance imaging (MRI) in detecting articular cartilage injuries in patients with glenohumeral instability. A secondary purpose was to assess the diagnostic performance of MRI for detection of Hill-Sachs and Bankart lesions. A cohort of 87 consecutive patients who underwent diagnostic MRI and shoulder arthroscopy for instability from 1997 to 2006 were identified. Fifty-five patients (63.2%) underwent MRI with intra-articular contrast medium and 32 patients (36.8%) underwent MRI without contrast medium. MR images were reviewed by two radiologists and interpreted by consensus for the presence of articular cartilage lesions (including Hill-Sachs and Bankart lesions), which were then confirmed by reviewing the operative report and images recorded at arthroscopy. Mean patient age was 27.0 ± 10.2 years with a mean clinical and radiographic follow-up of 29 (range 3-72) months. Cartilage injuries were detected arthroscopically in 55 patients (63%). Bankart and Hill-Sachs lesions were identified arthroscopically in 66 patients (75.9%) and 55 patients (63.2%) respectively. The overall sensitivity and specificity for detection of glenohumeral articular cartilage lesions by MRI were 87.2% and 80.6% respectively. The sensitivity and specificity of MRI in detecting Bankart lesions was 98.4% (95% CI 91.9, 99.7) and 95.2% (95% CI 77.3, 99.2) respectively. The sensitivity and specificity of MRI in detecting Hill-Sachs lesions was 96.3% (95% CI 87.6, 98.9%) and 90.6% (95% CI 75.7, 96.9) respectively. No statistically significant difference was found between MRI examinations with and without intra-articular gadolinium (p = 0.89). Magnetic resonance imaging demonstrates high sensitivity and specificity for the diagnosis of articular cartilage injuries in patients with glenohumeral instability. MRI with or without intra-articular contrast medium in this study were equally reliable as a non

There are no studies on utility of MRI in management of pediatric adnexal masses. To determine the diagnostic and therapeutic impact of pelvic MRI in adnexal masses in children and adolescents. We included 32 females age 18 years and younger who had adnexal masses and who underwent both pelvic ultrasound (US) and MRI. A radiologist retrospectively reviewed US and MR images and created a standard radiologic report for each patient. In a prospective theoretical fashion, two pediatric gynecologists reviewed the clinical data and US report for each patient and indicated conservative versus surgical management; in surgical cases the options were laparoscopy versus laparotomy, midline versus Pfannenstiel incision, and oophorectomy versus cystectomy. Subsequently, the gynecologists were presented the MRI report and were asked to indicate their treatment options again. A binomial test was conducted to determine the effect of adding MRI findings to the management plan. The addition of MRI significantly changed management in 10 of 32 patients (P=0.0322), with a change in surgical versus conservative treatment in 5, a change in laparotomy vs. laparoscopy in 2, and a change from oophorectomy to cystectomy along with change in incision in 3 cases. This was based on additional information provided by MRI regarding the nature of the mass in 8 cases and origin of the mass in 2 cases. Preoperative pelvic MRI findings might change the surgical management of pediatric patients with adnexal masses, so it is a valuable addition to the conventional workup in the clinical management.

Pelvic inflammatory disease (PID) is one of the major health problems of women of child-bearing age. Among the most serious complications of PID is the formation of a tubo-ovarian abscess (TOA). Early diagnosis of this condition may prevent serious surgical complications such as peritonitis and sepsis, which may be fatal. The purpose of this study was to investigate the efficacy of technetium-99m hexamethylpropylene amine oxime (HMPAO) leucocyte scintigraphy in the diagnosis of TOA. Twenty women with high clinical suspicion of TOA underwent {sup 99m}Tc-HMPAO leucocyte scintigraphy. The labelling of leucocytes with {sup 99m}Tc-HMPAO was performed according to a standard protocol. Scans were obtained at 1, 3 and 24 h following the injection of the labelled leucocytes. In eight cases the early and/or late scan was positive, in 11 cases it was negative, and in one case of ovarian cyst torsion, confirmed by laparoscopy, it showed slight uptake in the capsule of the cyst (false-positive). The sensitivity of {sup 99m}Tc-HMPAO leucocyte scintigraphy was 100%, specificity 91.6%, positive predictive value 89%, negative predictive value 100% and overall accuracy 95%. It is concluded that leucocyte scintigraphy is a non-invasive, safe, physiological and accurate procedure for the diagnosis of TOA. The 24-h scan is crucial, since in some cases the abscess was not clearly visualized on the early scan. Leucocyte scintigraphy may reduce the need for CT, diagnostic laparoscopy and unnecessary invasive surgical procedures. (orig.)

Cognitive psychology research supports the notion that experts use mental frameworks or "schemes", both to organize knowledge in memory and to solve clinical problems. The central purpose of this study was to determine the relationship between problem-solving strategies and the likelihood of diagnostic success. Think-aloud protocols were collected to determine the diagnostic reasoning used by experts and non-experts when attempting to diagnose clinical presentations in gastroenterology. Using logistic regression analysis, the study found that there is a relationship between diagnostic reasoning strategy and the likelihood of diagnostic success. Compared to hypothetico-deductive reasoning, the odds of diagnostic success were significantly greater when subjects used the diagnostic strategies of pattern recognition and scheme-inductive reasoning. Two other factors emerged as independent determinants of diagnostic success: expertise and clinical presentation. Not surprisingly, experts outperformed novices, while the content area of the clinical cases in each of the four clinical presentations demonstrated varying degrees of difficulty and thus diagnostic success. These findings have significant implications for medical educators. It supports the introduction of "schemes" as a means of enhancing memory organization and improving diagnostic success.

Objective: To assess the additional diagnostic value of contrast-enhanced ultrasound (CEUS) in the characterization of indeterminate solid hepatic lesions identified on non-diagnostic contrast-enhanced computed tomography (CT). Methods: Fifty-five solid hepatic lesions (1–4 cm in diameter) in 46 non-cirrhotic patients (26 female, 20 male; age ± SD, 55 ± 10 years) underwent CEUS after being detected on contrast-enhanced CT which was considered as non-diagnostic after on-site analysis. Two blinded independent readers assessed CT and CEUS scans and were asked to classify retrospectively each lesion as a malignant or benign based on reference diagnostic criteria for the different hepatic lesion histotypes. Diagnostic accuracy and confidence (area – A z – under ROC curve) were assessed by using gadobenate dimeglumine-enhanced magnetic resonance (MR) imaging (n = 30 lesions), histology (n = 7 lesions), or US follow-up (n = 18 lesions) as the reference standards. Results: Final diagnoses included 29 hemangiomas, 3 focal nodular hyperplasias, 1 hepatocellular adenoma, and 22 metastases. The additional review of CEUS after CT images improved significantly (P < .05) the diagnostic accuracy (before vs after CEUS review = 49% [20/55] vs 89% [49/55] – reader 1 and 43% [24/55] vs 92% [51/55] – reader 2) and confidence (A z , 95% Confidence Intervals before vs after CEUS review = .773 [.652–.895] vs .997 [.987–1] – reader 1 and .831 [.724–.938] vs .998 [.992–1] – reader 2). Conclusions: CEUS improved the characterization of indeterminate solid hepatic lesions identified on non-diagnostic contrast-enhanced CT by identifying some specific contrast enhancement patterns.

Background. Pneumoperitoneum is the presence of air outside the gut lumen as the hallmark of alimentary tract perforation. It can be spontaneous or traumatic in origin. The most frequent cause of spontaneous pneumoperitoneum is the perforation of gastric or duodenal ulcer and the aim of the study was to assess the diagnostic value of pneumoperitoneum on plain abdominal film. Patients and methods. This is a retrospective study based on the diagnostic value of pneumoperitoneum on plain abdominal film, with the patient in upright, supine and sometimes left lateral decubitus position. The study included 79 patients who were admitted to our hospital during a 2-year period of time (1998- 1999) and operated on for perforated gastroduodenal ulcer. Results. Ten (12.66 %) of 79 patients underwent operation without radiological procedure. Sixty-nine (87.34 %) patients were examined radiographically and 53 (76.81 %) of them had signs of pneumoperitoneum initially on the plain film. Conclusions. The most common cause of pneumoperitoneum was perforated duodenal ulcer in elderly male patients. The most frequent sign of pneumoperitoneum was the crescent shaped free air beneath the diaphragm.

Pediatric ovarian torsion: an uncommon clinical entity

OpenAIRE

Rajwani, Kapil M; Mahomed, Anies

2014-01-01

Key Clinical Message Pediatric ovarian torsion is an infrequent diagnosis and it often mimics acute appendicitis. Most cases are due to underlying ovarian pathology and if left untreated, ovarian torsion may eventually cause peritonitis. Emergency exploratory laparoscopy represents a valuable diagnostic and therapeutic tool in suspected ovarian torsion.

Myocardial perfusion scintigraphy (MPS) in patients not reaching 85% of the maximum predicted heart rate (MPHR) has reduced sensitivity. In an attempt to maintain diagnostic sensitivity without losing functional exercise data, a new exercise and dipyridamole combined protocol (EDCP) was developed. Our aim was to evaluate the feasibility and safety of this protocol and to compare its diagnostic sensitivity against standard exercise and dipyridamole protocols. In patients not reaching a sufficient exercise (SE) test and with no contraindications, 0.56 mg/kg of dipyridamole were IV administered over 1 minute simultaneously with exercise, followed by 99mTc-MIBI injection. Of 155 patients, 41 had MPS with EDCP, 47 had a SE test (≥ 85% MPHR) and 67 underwent the dipyridamole alone test (DIP). They all underwent coronary angiography within 3 months. The three stress methods for diagnosis of coronary lesions had their sensitivity compared. For stenosis ≥ 70%, EDCP yielded 97% sensitivity, SE 90% and DIP 95% (p = 0.43). For lesions ≥ 50%, the sensitivities were 94%, 88% and 95%, respectively (p = 0.35). Side effects of EDCP were present in only 12% of the patients, significantly less than with DIP (p < 0.001). The proposed combined protocol is a valid and safe method that yields adequate diagnostic sensitivity, keeping exercise prognostic information in patients unable to reach target heart rate, with fewer side effects than the DIP.

Incidence of Bradycardia and Outcomes of Patients Who Underwent Orbital Atherectomy Without a Temporary Pacemaker.

Lee, Michael S; Nguyen, Heajung; Shlofmitz, Richard

2017-02-01

We analyzed the incidence of bradycardia and the safety of patients with severely calcified coronary lesions who underwent orbital atherectomy without the insertion of a temporary pacemaker. The presence of severely calcified coronary lesions can increase the complexity of percutaneous coronary intervention due to the difficulty in advancing and optimally expanding the stent. High-pressure inflations to predilate calcified lesions may cause angiographic complications like perforation and dissection. Suboptimal stent expansion is associated with stent thrombosis and restenosis. Orbital atherectomy safely and effectively modifies calcified plaque to facilitate optimal stent expansion. The incidence of bradycardia in orbital atherectomy is unknown. Fifty consecutive patients underwent orbital atherectomy from February 2014 to September 2016 at our institution, none of whom underwent insertion of a temporary pacemaker. The final analysis included 47 patients in this retrospective study as 3 patients were excluded because of permanent pacemaker implantation. The primary endpoint was significant bradycardia, defined as bradycardia requiring emergent pacemaker placement or a heart rate pacemaker appears to be safe.

Current WHO testing guidelines for resource limited settings diagnose HIV on the basis of screening tests without a confirmation test due to cost constraints. This leads to a potential risk of false positive HIV diagnosis. In this paper, we evaluate the dilution test, a novel method for confirmation testing, which is simple, rapid, and low cost. The principle of the dilution test is to alter the sensitivity of a rapid diagnostic test (RDT) by dilution of the sample, in order to screen out the cross reacting antibodies responsible for falsely positive RDT results. Participants were recruited from two testing centres in Ethiopia where a tiebreaker algorithm using 3 different RDTs in series is used to diagnose HIV. All samples positive on the initial screening RDT and every 10th negative sample underwent testing with the gold standard and dilution test. Dilution testing was performed using Determine™ rapid diagnostic test at 6 different dilutions. Results were compared to the gold standard of Western Blot; where Western Blot was indeterminate, PCR testing determined the final result. 2895 samples were recruited to the study. 247 were positive for a prevalence of 8.5 % (247/2895). A total of 495 samples underwent dilution testing. The RDT diagnostic algorithm misclassified 18 samples as positive. Dilution at the level of 1/160 was able to correctly identify all these 18 false positives, but at a cost of a single false negative result (sensitivity 99.6 %, 95 % CI 97.8-100; specificity 100 %, 95 % CI: 98.5-100). Concordance between the gold standard and the 1/160 dilution strength was 99.8 %. This study provides proof of concept for a new, low cost method of confirming HIV diagnosis in resource-limited settings. It has potential for use as a supplementary test in a confirmatory algorithm, whereby double positive RDT results undergo dilution testing, with positive results confirming HIV infection. Negative results require nucleic acid testing to rule out false

The aim of this study was to analyze and compare the vocal quality in patients who underwent either submucosal turbinectomy or radiofrequency cauterization. In this study, we enrolled 60 patients diagnosed with inferior concha hypertrophy. These patients were divided into two groups by using computer program "Research Randomizer." Of the 60 patients, 30 underwent submucosal inferior turbinoplasty and 30 underwent radiofrequency cauterization. The control group was composed of 30 healthy adults with no nasal or upper aerodigestive system pathology. The patients were checked at weeks 1, 2, and 4. Voice records were taken before the procedure and at week 4 postprocedure. The mean age of patients in the inferior turbinoplasty group was 29.4 years (range: 19-42 years); in the radiofrequency group, it was 30.30 years (range: 18-50 years). There was no statistical difference in age between groups. In the inferior turbinoplasty group, there were 16 male and 14 female patients, and in the radiofrequency group, there were 13 male and 17 female patients. There was no significant difference in the number of males and females between groups. Voice professionals, especially singers, actors, and actresses, should be informed about possible voice changes before undergoing endonasal surgery because these individuals are more sensitive to changes in resonance organs. We believe that voice quality should be regarded as a highly important parameter when measuring the success of endonasal surgery. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc.

2010-01-01

This study aimed to evaluate the diagnostic yield of preoperative computed tomography (CT) imaging and the validity of surgical intervention based on the clinical decision to perform surgery for lung cancer or suspected lung cancer. We retrospectively evaluated 1755 patients who had undergone pulmonary resection for lung cancer or suspected lung cancer. CT scans were performed on all patients. Surgical intervention to diagnose and treat was based on a medical staff conference evaluation for the suspected lung cancer patients who were pathologically undiagnosed. We evaluated the relation between resected specimens and preoperative CT imaging in detail. A total of 1289 patients were diagnosed with lung cancer by preoperative pathology examination; another 466 were not pathologically diagnosed preoperatively. Among the 1289 patients preoperatively diagnosed with lung cancer, the diagnoses were confirmed postoperatively in 1282. Among the 466 patients preoperatively undiagnosed, 435 were definitively diagnosed with lung cancer, and there were 383 p-stage I disease patients. There were 38 noncancerous patients who underwent surgery with a diagnosis of confirmed or suspected lung cancer. Among the 1755 patients who underwent surgery, 1717 were pathologically confirmed with lung cancer, and the diagnostic yield of preoperative CT imaging was 97.8%. Among the 466 patients who were preoperatively undiagnosed, 435 were compatible with the predicted findings of lung cancer. Diagnostic yields of preoperative CT imaging based on clinical evaluation are sufficiently reliable. Diagnostic surgical intervention was acceptable when the clinical probability of malignancy was high and the malignancy was pathologically undiagnosed. (author)

To evaluate the diagnostic performance of ultrasound and to determine which ultrasound findings are useful to differentiate appendicitis from non-appendicitis in patients who underwent ultrasound re-evaluation owing to equivocal CT features of acute appendicitis. 62 patients who underwent CT examinations for suspected appendicitis followed by ultrasound re-evaluation owing to equivocal CT findings were included. Equivocal CT findings were considered based on the presence of only one or two findings among the CT criteria, and ultrasound re-evaluation was done based on a predefined structured report form. The diagnostic performance of ultrasound and independent variables to discriminate appendicitis from non-appendicitis were assessed. There were 27 patients in the appendicitis group. The overall diagnostic performance of ultrasound re-evaluation was sensitivity of 96.3%, specificity of 91.2% and accuracy of 91.9%. In terms of the performance of individual ultrasound findings, probe-induced tenderness showed the highest accuracy (86.7%) with sensitivity of 74% and specificity of 97%, followed by non-compressibility (accuracy 71.7%, sensitivity 85.2% and specificity 60.6%). The independent ultrasound findings for discriminating appendicitis were non-compressibility (p = 0.002) and increased flow on the appendiceal wall (p = 0.001). Ultrasound re-evaluation can be used to improve diagnostic accuracy in cases with equivocal CT features for diagnosing appendicitis. The presence of non-compressibility and increased vascular flow on the appendix wall are useful ultrasound findings to discriminate appendicitis from non-appendicitis. Advances in knowledge: Ultrasound re-evaluation is useful to discriminate appendicitis from non-appendicitis when CT features are inconclusive.

A randomised controlled trial to assess the efficacy of Laparoscopic Uterosacral Nerve Ablation (LUNA) in the treatment of chronic pelvic pain: The trial protocol [ISRCTN41196151].

BACKGROUND: Chronic pelvic pain is a common condition with a major impact on health-related quality of life, work productivity and health care utilisation. The cause of the pain is not always obvious as no pathology is seen in 40-60% of the cases. In the absence of pathology there is no established treatment. The Lee-Frankenhauser sensory nerve plexuses and parasympathetic ganglia in the uterosacral ligaments carry pain from the uterus, cervix and other pelvic structures. Interruption of these nerve trunks by laparoscopic uterosacral nerve ablation (LUNA) may alleviate pain. However, the balance of benefits and risks of this intervention have not been reliably assessed. LUNA has, nevertheless, been introduced into practice, although there remains controversy regarding indications for LUNA. Hence, there is an urgent need for a randomised controlled trial to confirm, or refute, any worthwhile effectiveness. The principal hypothesis is that, in women with chronic pelvic pain in whom diagnostic laparoscopy reveals either no pathology or mild endometriosis (AFS score life quality at 12 months.

ObjectiveThe purpose of our study was to evaluate the diagnostic accuracy of MRI-guided percutaneous transthoracic needle biopsy (PTNB) of solitary pulmonary nodules (SPNs).MethodsRetrospective review of 69 patients who underwent MR-guided PTNB of SPNs was performed. Each case was reviewed for complications. The final diagnosis was established by surgical pathology of the nodule or clinical and imaging follow-up. Pneumothorax rate and diagnostic accuracy were compared between two groups according to nodule diameter (≤2 vs. >2 cm) using χ{sup 2} chest and Fisher’s exact test, respectively.ResultsThe success rate of single puncture was 95.6 %. Twelve (17.4 %) patients had pneumothorax, with 1 (1.4 %) requiring chest tube insertion. Mild hemoptysis occurred in 7 (7.2 %) patients. All of the sample material was sufficient for histological diagnostic evaluation. Pathological analysis of biopsy specimens showed 46 malignant, 22 benign, and 1 nondiagnostic nodule. The final diagnoses were 49 malignant nodules and 20 benign nodules basing on postoperative histopathology and clinical follow-up data. One nondiagnostic sample was excluded from calculating diagnostic performance. A sensitivity, specificity, accuracy, positive predictive value, and negative predictive value in diagnosing SPNs were 95.8, 100, 97.0, 100, and 90.9 %, respectively. Pneumothorax rate, diagnostic sensitivity, and accuracy were not significantly different between the two groups (P > 0.05).ConclusionsMRI-guided PTNB is safe, feasible, and high accurate diagnostic technique for pathologic diagnosis of pulmonary nodules.

Paraduodenal hernias are the most common type of congenital internal hernia. Because of its overall rare incidence, this entity is often overlooked during initial assessment of the patient. Lack of specific diagnostic criteria also makes diagnosis exceedingly difficult, and the resulting diagnostic delays can lead to tragic outcomes for patients. Despite these perceived barriers to timely diagnosis, there may be specific radiographic findings that, when combined with the appropriate constellation of clinical symptoms, would aid in diagnosis. This patient first presented at 8 years of age with vague symptoms of postprandial emesis, chronic abdominal pain, nausea, and syncope. Over the span of 6 years he was evaluated 2 to 3 times a year with similar complaints, all of which quickly resolved spontaneously. He underwent multiple laboratory, imaging, and endoscopic studies, which were nondiagnostic. It was not until he developed signs of a high-grade obstruction and extremis that he was found to have a large left paraduodenal hernia that had volvulized around the superior mesenteric axis. This resulted in the loss of the entire superior mesenteric axis distribution of the small and large intestine and necrosis of the duodenum. In cases of chronic intermittent obstruction without clear etiology, careful attention and consideration should be given to the constellation of symptoms, imaging studies, and potential use of diagnostic laparoscopy. Increased vigilance by primary care and consulting physicians is necessary to detect this rare but readily correctable condition. Copyright © 2015 by the American Academy of Pediatrics.

To determine the diagnostic and therapeutic impact of dual-energy computed tomography (DECT) in gout. Forty-three patients with (n = 20) and without a history of gout (n = 23) showing non-specific soft tissue deposits underwent DECT after unrewarding arthrocentesis. Two blinded, independent readers evaluated DECT for the presence of urate crystals. Clinical diagnosis, clinically suspected urate crystal locations, diagnostic thinking and therapeutic decisions were noted before and after DECT. Clinical 1-month follow-up was obtained. DECT showed urate in 26/43 patients (60 %). After DECT, clinical diagnosis of gout was withdrawn in 17/43 (40 %) and was maintained in 16/43 patients (37 %). In 10/43 patients (23 %) the diagnosis was maintained, but DECT revealed urate in clinically unsuspected locations. In 23/43 patients (53 %), a treatment-change based on DECT occurred. Changes in diagnostic thinking occurred more frequently in patients without a history of gout (p < 0.001), changes in therapeutic decisions more frequently in patients with a history of gout (p = 0.014). Clinical follow-up indicated beneficial effects of DECT-based diagnoses in 83 % of patients. In patients with or without a history of gout and a recent suspicion for gouty arthritis with an unrewarding arthrocentesis, DECT has a marked diagnostic and therapeutic impact when hyperdense soft-tissue deposits are present.

Use of intraoperative fluoroscopy during laparotomy to identify fragments of retained Essure microinserts: case report.

Science.gov (United States)

Howard, David L; Christenson, Paul J; Strickland, Julie L

2012-01-01

In previous case-reports of Essure microinsert perforation, the microinsert was successfully removed at laparoscopy. Herein is discussed the scenario of persistent pelvic pain over several years after an apparently successful laparoscopic retrieval of a perforating right-sided microinsert. In the interim, the patient underwent 2 unsuccessful exploratory laparotomy procedures in an attempt to retrieve additional microinsert fragments that had perforated the uterus. Successful management of Essure microinsert perforation in this patient ultimately required use of intraoperative fluoroscopy. Surgeons performing laparoscopy or laparotomy to retrieve Essure microinserts that have perforated should be aware that these are not always visible to the naked eye, and there should be a low threshold to use intraoperative fluoroscopy to ensure that all perforating fragments have been removed.

Fertility after childhood haemopoietic stem cell transplant (HSCT) is a major concern. Conditioning regimens before HSCT present a high risk (>80%) of ovarian failure. Since 2000, we have proposed cryopreservation of ovarian tissue to female patients undergoing HSCT at our centre, to preserve future fertility. After clinical and haematological evaluation, the patients underwent ovarian tissue collection by laparoscopy. The tissue was analysed by histologic examination to detect any tumour contamination and then frozen following the slow freezing procedure and cryopreserved in liquid nitrogen. From August 2000 to September 2013, 47 patients planned to receive HSCT, underwent ovarian tissue cryopreservation. The median age at diagnosis was 11.1 years and at the time of procedure it was 13 years, respectively. Twenty-four patients were not pubertal at the time of storage, whereas 23 patients had already experienced menarche. The median time between laparoscopy and HSCT was 25 days. Twenty-six out of 28 evaluable patients (93%) developed hypergonadotropic hypogonadism at a median time of 23.3 months after HSCT. One patient required autologous orthotopic transplantation that resulted in one live birth. Results show a very high rate of iatrogenic hypergonadotropic hypogonadism, highlighting the need for fertility preservation in these patients.

Full Text Available Objectives: Currently, diagnostic laparoscopy (DL is recommended for the left thoraco-abdominal region penetrating injuries (LTARP. However, organ and diaphragmatic injury may not be detected in all of these patients. Our aim is to focus on this LTARP patient group without any operative findings and to highlight the evaluation of diagnostic tools in the high-tech era for a possible selected conservative treatment. Material and methods: The patients who were admitted to ED due to LTARP, and who underwent routine DL were evaluated retrospectively in terms of demographic, clinical, radiological, and operative findings of the patients. Results: The current study included 79 patients with LTARP. In 44 of 79 patients, abdominal injury was not detected. In 30 patients an isolated diaphragmatic injury was revealed and in 4 patients a visceral injury was accompanying to diaphragmatic injury. Surgical findings revealed that the diaphragm was the organ most likely to sustain injury. In patients with more than one positive diagnostic findings need for surgery rate was 61.5%, however; in patients with one positive diagnostic finding (n = 53, positive surgical finding rate was only 35.8%, (p = 0.03. Regarding the combined use of all diagnostic tools in these patients; such as physical examination, plain chest X-ray, and computed tomography, when this method was used for pre-operative diagnosis, sensitivity was measured as 82.7%, specificity 84.1%, PPV 77.4% and NPV 88.1%. Conclusion: Although DL is reliable for diagnosis of diaphragmatic and visceral injury in patients with LTARP. However, individual decision making for laparoscopic intervention is needed to prevent morbidity of an unnecessary operation under emergent setting due to high rates of negative intraabdominal findings.

A 70-year-old man with distal bile duct carcinoma underwent a subtotal stomach-preserving pancreaticoduodenectomy without adjuvant chemotherapy. One and a half years after the surgery, elevated levels of serum SPan-1(38.1 U/mL)were observed and CT scans demonstrated a solitary metastasis, 25mm in size, in segment 8 of the liver. The patient received 2 courses of gemcitabine-cisplatin combination chemotherapy. No new lesions were detected after chemotherapy and the patient underwent a partial liver resection of segment 8. The pathological examination revealed a metachronous distant metastasis originating from the bile duct carcinoma. Subsequently, the patient received S-1 adjuvant chemotherapy for 6 months. Following completion of all therapies, the patient survived without tumor recurrence for 3 years and 10 months after the initial operation. Thus, surgical interventions might be effective in improving prognosis among selected patients with postoperative liver metastasis of bile duct carcinoma.

To evaluate the diagnostic role of venous and arterial duplex scanning in neurogenic thoracic outlet syndrome (NTOS). Retrospective review of patients who underwent duplex ultrasonography prior to first rib resection and scalenectomy (FRRS) for NTOS from 2005 to 2013. Abnormal scans included ipsilateral compression (IC) with abduction of the symptomatic extremity (>50% change in subclavian vessel flow), contralateral (asymptomatic side) compression (CC) or bilateral compression (BC). A total of 143 patients (76% female, average age 34, range 13-59) underwent bilateral preoperative duplex scanning. Ipsilateral compression was seen in 44 (31%), CC in 12 (8%), and BC in 14 (10%). Seventy-three (51%) patients demonstrated no compression. Patients with IC more often experienced intraoperative pneumothoraces (49% vs. 25%, P duplex ultrasonography can assist in NTOS diagnosis. Ipsilateral compression on abduction often correlates with Adson testing. © The Author(s) 2016.

Purpose: Today, distinguishing metastatic lymph nodes from secondary benign inflammatory ones via using non-invasive methods is increasingly favorable. In this study, the diagnostic value of chemical shift artifact (CSA) in magnetic resonance imaging (MRI) was evaluated to distinguish benign lymphadenopathy. Subjects and methods: A prospective intraindividual internal review board-approved study was carried out on 15 men and 15 women having lymphadenopathic lesions in different locations of the body who underwent contrast-enhanced dynamic MR imaging at 1.5 T. Then, the imaging findings were compared with pathology reports, using the statistics analyses. Results: Due to the findings of the CSA existence in MRI, a total of 56.7% of the studied lesions (17 of 30) were identified as benign lesions and the rest were malignant, whereas the pathology reports distinguished twelve malignant and eighteen benign cases. Furthermore, the CSA findings comparing the pathology reports indicated that CSA, with confidence of 79.5%, has a significant diagnostic value to differentiate benign lesions from malignant ones. Conclusion: Our study demonstrated that CSA in MR imaging has a suitable diagnostic potential nearing readiness for clinical trials. Furthermore, CSA seems to be a feasible tool to differentiate benign lymph nodes from malignant ones; however, further studies including larger numbers of patients are required to confirm our results.

The diagnostic value of the vacuum phenomenon between the femoral head and the acetabulum, and time frame of its occurrence after application of traction is an important clinical question. The resulting arthrogram may outline the shape, location, and extent of cartilage lesions prior to arthroscopy of the hip joint. The presence, duration, and diagnostic information of the vacuum phenomenon were evaluated in 24 hips that underwent arthroscopy. The operative diagnosis was compared to the results of imaging studies and to findings obtained during a traction trial prior to arthroscopy. Indications for arthroscopy included avascular necrosis, labral tears, loose bodies, osteoarthrosis, and intractable hip pain. In 22 hips the vacuum phenomenon developed within 30 seconds after application of traction. The most important data obtained from the vacuum phenomenon was the location and extent of femoral head articular cartilage detachment and the presence of nonossified loose bodies. The vacuum phenomenon did not reveal labral or acetabular cartilage pathology in any of these patients. The vacuum phenomenon obtained during the trial of traction can add valuable information prior to hip arthroscopy. Femoral head articular cartilage detachment was best documented by this method. The hip arthroscopist should utilize this diagnostic window routinely prior to hip arthroscopy. PMID:24977068

To explore the effects of the combined therapy of heat sensitive moxibustion and acupoint injection on endometrial receptivity of hypdrosalphinx infertility in the patients after hysteroscopy and laparoscopy on the base of routine post-operative anti-inflammation. A total of 210 patients of hypdrosalphinx infertility after hysteroscopy and laparoscopy were divided into a combined therapy group, a heat sensitive moxibustion group and a control group, 70 cases in each one according to the random number table. In the control group, the intravenous drip of cefoxitin sodium was adopted, and the anti-inflammation treatment was given for 1 week after operation. In the heat sensitive moxibustion group, on the basis of the treatment as the control group, the heat sensitive moxibustion was applied after vaginal bleeding stopped. The acupoints were Yaoyangguan (GV 3), Guanyuan (CV 4), Qihai (CV 6), Shenshu (BL 23), Sanyinjiao (SP 6), Yinlingquan (SP 9) and Zigong (EX-CA1). The acupoints were modified according to the different syndromes. In the combined therapy group, on the basis of the regimen as the heat sensitive moxibustion group, after vaginal bleeding stopped, the acupoint injection was given alternatively at bilateral Tiangong (extra, 1.0 cm inferior and bilateral to the cervix) with lidocaine 1 mL, amikacin 2 mL and salvia injection 2 mL. The treatment was given once every day, the treatment for 10 times as one course and a total of 3 courses were required. The endometrial type, thickness, uterine arterial plusatility index (PI) and resistance index (RI) were observed in the patients of each group. After treatment, the numbers of A-type endometrial type in the combined therapy group and the heat sensitive moxibustion group were remarkably higher than those of the control group [57.1% (40/7) vs 31.4% (22/70), 50.0% (35/70) vs 31.4% (22/70), both P <0.05]. The endometrial thickness after treatment was all increased as compared with that before treatment in each group

Non-invasive diagnostic workup of patients with suspected stable angina by combined computed tomography coronary angiography and magnetic resonance perfusion imaging

International Nuclear Information System (INIS)

Kirschbaum, S.W.; Nieman, K.; Springeling, T.

2011-01-01

The background of this study was to evaluate additional adenosine magnetic resonance perfusion (MRP) imaging in the diagnostic workup of patients with suspected stable angina with computed tomography coronary angiography (CTCA) as first-line diagnostic modality. Two hundred and thirty symptomatic patients (male, 52%; age, 56 year) with suspected stable angina underwent CTCA. In patients with a stenosis of >50% as visually assessed, MRP was performed and the quantitative myocardial perfusion reserve index (MPRI) was calculated. Coronary flow reserve (CFR) using invasive coronary flow measurements served as the standard of reference. CTCA showed non-significant coronary artery disease (CAD) in 151/230 (66%) patients and significant CAD in 79/230 patients (34%), of whom 50 subsequently underwent MRP and CFR. MRP showed reduced perfusion in 32 patients (64%), which was confirmed by CFR in 27 (84%). All 18 cases of normal MRP (36%) were confirmed by CFR. The positive likelihood ratio of MRP for the presence of functional significant disease in patients with a lesion on CTCA was 4.49 (95% confidence interval [CI] 2.12-9.99). The negative likelihood ratio was 0.05 (95% CI 0.01-0.34). CTCA as first-line diagnostic modality excluded coronary artery disease in a high percentage of patients referred for diagnostic workup of suspected stable angina. MRP made a significant contribution to the detection of functional significant lesions in patients with a positive CTCA. (author)

Patient and surgeon factors are associated with the use of laparoscopy in appendicitis.

LENUS (Irish Health Repository)

McCartan, D P

2012-02-01

Aim The use of a minimally invasive approach to treat appendicitis has yet to be universally accepted. The objective of this study was to examine recent trends in Ireland in the surgical management of acute appendicitis. Method Data were obtained from the Irish Hospital In-Patient Enquiry system for patients discharged with a diagnosis of appendicitis between 1999 and 2007. An anonymous postal survey was sent to all general surgeons of consultant and registrar level in Ireland to assess current attitudes to the use of laparoscopic appendectomy. Results The use of laparoscopic appendectomy increased throughout the study and was the most common approach for appendectomy in 2007. Multivariate analysis revealed age under 50 years (OR = 1.51), female sex (OR = 2.84) and residence in high-density population areas (OR = 4.15) as predictive factors for undergoing laparoscopic appendectomy in the most recent year of the study. While 97% of surgeons reported current use of laparoscopy in patients with acute right iliac fossa pain, in most cases it was selective. Surgeons in university teaching hospitals (42 of 77; 55%) were more likely to report using laparoscopic appendectomy for all cases of appendicitis than those in regional (six of 23; 26%) or general (13 of 53; 25%) hospitals (P = 0.048). Conclusion This study has demonstrated a significant increase in laparoscopic appendectomy, yet a variety of patient and surgeon factors contribute to the choice of procedure. Differences in the perception of benefit of the laparoscopic approach amongst surgeons appears to be an important factor in determining the operative approach for appendectomy.

Full Text Available AbstractBackground:Myocardial perfusion scintigraphy (MPS in patients not reaching 85% of the maximum predicted heart rate (MPHR has reduced sensitivity.Objectives:In an attempt to maintain diagnostic sensitivity without losing functional exercise data, a new exercise and dipyridamole combined protocol (EDCP was developed. Our aim was to evaluate the feasibility and safety of this protocol and to compare its diagnostic sensitivity against standard exercise and dipyridamole protocols.Methods:In patients not reaching a sufficient exercise (SE test and with no contraindications, 0.56 mg/kg of dipyridamole were IV administered over 1 minute simultaneously with exercise, followed by 99mTc-MIBI injection.Results:Of 155 patients, 41 had MPS with EDCP, 47 had a SE test (≥ 85% MPHR and 67 underwent the dipyridamole alone test (DIP. They all underwent coronary angiography within 3 months. The three stress methods for diagnosis of coronary lesions had their sensitivity compared. For stenosis ≥ 70%, EDCP yielded 97% sensitivity, SE 90% and DIP 95% (p = 0.43. For lesions ≥ 50%, the sensitivities were 94%, 88% and 95%, respectively (p = 0.35. Side effects of EDCP were present in only 12% of the patients, significantly less than with DIP (p < 0.001.Conclusions:The proposed combined protocol is a valid and safe method that yields adequate diagnostic sensitivity, keeping exercise prognostic information in patients unable to reach target heart rate, with fewer side effects than the DIP.

Full Text Available Background. A nonrecognized pneumothorax (PTX may become a life-threatening tension PTX. A reliable point-of-care diagnostic tool could help in reduce this risk. For this purpose, we investigated the feasibility of the use of the PneumoScan, an innovative device based on micropower impulse radar (MIR. Patients and Methods. addition to a standard diagnostic protocol including clinical examination, chest X-ray (CXR, and computed tomography (CT, 24 consecutive patients with chest trauma underwent PneumoScan testing in the shock trauma room to exclude a PTX. Results. The application of the PneumoScan was simple, quick, and reliable without functional disorder. Clinical examination and CXR each revealed one and PneumoScan three out of altogether four PTXs (sensitivity 75%, specificity 100%, positive predictive value 100%, and negative predictive value 95%. The undetected PTX did not require intervention. Conclusion. The PneumoScan as a point-of-care device offers additional diagnostic value in patient management following chest trauma. Further studies with more patients have to be performed to evaluate the diagnostic accuracy of the device.

To assess the outcome of aggressive but conservative laparoscopic surgery in the treatment of severe endometriosis involving the rectum. Retrospective study (Canadian Task Force classification III). Endosurgery unit of a tertiary referral center. One hundred sixty-nine women. Laparoscopy or laparotomy. The procedure was completed successfully laparoscopically in 145 (86%) and by laparotomy in 24 women (14%). The rate of preoperative symptoms was higher in 25 women who underwent bowel resection compared with those who had other bowel surgery. In addition to bowel surgery, excision of uterosacral ligaments, adhesiolysis, excision of endometrioma, and oophorectomy were the four most commonly performed procedures. At 35-month follow-up 61 patients (36%) required further surgery for pain. The average time between primary and repeat surgery was 16 months. This second operation was performed by laparoscopy in over three-fourths of the women. Overall recurrent endometriosis was found in 26 patients (15%). Overall morbidity associated with all surgery was 12.4%. Surgery for endometriosis of the cul-de-sac and bowel involves some of the most difficult dissections encountered, but it can be accomplished successfully with the low postoperative morbidity typical of laparoscopy.

We evaluate the feasibility and efficacy of combination chemotherapy including single intraperitoneal( IP)administration of paclitaxel(PTX), followed by triplet chemotherapy(PTX, cisplatin[CDDP]and S-1: PCS)for CY1P0 gastric cancer. First of all, we performed staging laparoscopy and confirmed CY1P0, and secondary, administrated PTX intraperitoneally. Thirdly, patients received PCS chemotherapy for 2 courses. After antitumor effect had been confirmed, we performed second look laparoscopy. In the case of CY0P0, we performed gastrectomy with D2 lymph nodes dissection. Total 4 patients were enrolled. Grade 3 leukopenia and neutropenia were observed in one patient while intraperitoneal and systemic-chemotherapy. One patients showed PR and 3 patients showed SD. All patients underwent second look laparoscopy. CY0P0 was observed in all patients and gastrectomy with D2 dissection was performed for all patients. Postoperative complications were observed in 2 patients. Two patients were still alive without recurrence, while the remaining 2 had died of liver metastasis and #16 LN metastasis. Combination chemotherapy including single IP PTX followed by PCS systemic-chemotherapy for CY1P0 gastric cancer is feasible and efficient.

Full Text Available Isolated tubal torsion -a rare cause of acute abdomen in children-is usually difficult to diagnose because of non-specific findings. Surgical salphingectomy is required in delayed diagnosis in most cases. Three sexual inactive adolescents diagnosed in isolated tubal torsion (ITT were discussed for its diagnostic features and surgical management. Laboratory tests and radiological studies including ultrasonography (US, color doppler ultrasound were performed in all patients after evaluation for acute lower abdominal pain in emergency department and they underwent surgical intervention with laparotomy (n:2 and laparoscopy (n:1. One of the patients in this study had salpingectomy. Detorsion of the fallopian tube and cyst excision were performed in the remaining two patients who also had paratubal cysts. There was no recurrence in these patients during the follow-up for 3 and 2 years. The isolated tubal torsion should be kept in mind and early surgical management is essential in order to preserve fallopian tube because of its importance in fertility.

Infective endocarditis in a patient after kidney transplantation is a serious infective complication which increases the risk of loss of the graft and also the mortality of patients. The most important predisposing factor is the immunosuppressive therapy - mainly induction immunosuppression.Material and case description: 250 patients underwent kidney transplantation throughout the period of 12 years in the Transplant Center Martin. This set of patients included 5 patients (2 %) after heart valve replacement. We present the case of a patient after kidney transplantation with development of endocarditis of the bioprosthesis of the aortic valve one month after successful kidney transplantation. Diagnostics of endocarditis by standard procedures (examination by transthoracic echocardiogram, transesophageal echocardiography, hemocultures) was unsuccessful. We rarely diagnosed endocarditis only by PET-CT examination with a consequent change of the antibiotic treatment and successful managing of this post-transplant complication. Endocarditis after kidney transplantation is a serious complication which significantly worsens the mortality of patients. The risk of development of infective endocarditis after transplantation is also increased by induction, mainly by antithymocyte globulin. Diagnostics only by PET-CT examination is rare; however, in this case it fundamentally changed the approach to the patient and led to a successful treatment.

2015-01-01

To investigate the diagnostic performance of computed tomography angiography (CTA) in identifying the cause of bleeding and to determine the clinical features associated with a positive test result of CTA in patients visiting emergency department with overt gastrointestinal (GI) bleeding. We included 111 consecutive patients (61 men and 50 women; mean age: 63.4 years; range: 28-89 years) who visited emergency department with overt GI bleeding. They underwent CTA as a first-line diagnostic modality from July through December 2010. Two radiologists retrospectively reviewed the CTA images and determined the presence of any definite or potential bleeding focus by consensus. An independent assessor determined the cause of bleeding based on other diagnostic studies and/or clinical follow-up. The diagnostic performance of CTA and clinical characteristics associated with positive CTA results were analyzed. To identify a definite or potential bleeding focus, the diagnostic yield of CTA was 61.3% (68 of 111). The overall sensitivity, specificity, positive predictive value (PPV), and negative predictive value were 84.8% (67 of 79), 96.9% (31 of 32), 98.5% (67 of 68), and 72.1% (31 of 43), respectively. Positive CTA results were associated with the presence of massive bleeding (p = 0.001, odds ratio: 11.506). Computed tomography angiography as a first-line diagnostic modality in patients presenting with overt GI bleeding showed a fairly high accuracy. It could identify definite or potential bleeding focus with a moderate diagnostic yield and a high PPV. CTA is particularly useful in patients with massive bleeding.

Full Text Available BACKGROUND: Clinical experiences of adults who underwent surgery for esophageal atresia at birth is limited. There is some evidence that suggests considerable long-term morbidity, partly because of dysphagia, which has been reported in up to 85% of adult patients who undergo surgery for esophageal atresia. The authors hypothesized that dysphagia in this population is caused by dysmotility and/or anatomical anomalies.

Coronary angiography (CAG) is an invasive diagnostic procedure, which could lead to procedure related complications. One of the well known post-procedural complications is cerebral embolic infarction with or without symptoms. Silent embolic cerebral infarction (SECI) has clinical significance because it can progress to a decline in cognitive function and increase the risk of dementia in the long term. The aim of this study was to detect the incidence and predictors of SECI after diagnostic CAG using diffusion-weighted magnetic resonance imaging (DW-MRI). A total of 197 patients with coronary artery disease who underwent DW-MRI for evaluation of intracranial vasculopathy before coronary artery bypass graft surgery were retrospectively enrolled in the present study. DW-MRI was performed within 48 h after diagnostic CAG. SECI was diagnosed as presence of focal bright high signal intensity in DW-MRI. Patients were divided into groups according to presence/absence of SECI (+ SECI vs. - SECI, respectively). The clinical and angiographic characteristics were analyzed and independent predictors were evaluated. Of the 197 patients, SECI occurred in 20 patients (10.2%) after diagnostic CAG. Age, female gender, frequency of underlying atrial fibrillation, extent of coronary disease, and fluoroscopic time during diagnostic CAG were not different between the + SECI and - SECI groups. Left ventricular ejection fraction was significantly lower in the + SECI group than in the - SECI group (45.9 ± 8.5% vs. 51.4 ± 13.1%, p=0.014) and performance rate of internal mammary artery (IMA) angiography was significantly higher in the + SECI group compared with the - SECI group (85% vs. 37.2%, pSECI (OR=14.642; 95% CI=3.201 to 66.980, p=0.001). The incidence of SECI after diagnostic CAG was not infrequent. Diagnostic CAG with IMA angiography may increase the risk of SECI. Copyright © 2009 Elsevier Ireland Ltd. All rights reserved.

Isolated Fallopian Tube Torsion in Adolescents

2013-01-01

Full Text Available Background. Fallopian tube torsion is a rare cause of acute abdomen, occurring commonly in females of reproductive age. It lacks pathognomonic symptoms, signs, or imaging features, thus causing delay in surgical intervention. Case. We report two cases of isolated fallopian tube torsion in adolescent girls. In the first case a 19-year-old patient presented with acute pain in the left iliac region associated with episodes of vomiting for one day and mild tenderness on examination. Laparoscopy revealed left sided twisted fallopian tube associated with hemorrhagic cyst of ovary. The tube was untwisted and salvaged. In another case an 18-year-old virgin girl presented with similar complaints since one week, associated with mild tenderness in the lower abdomen and tender cystic mass on per rectal examination. On laparoscopy right twisted fallopian tube associated with a paratubal cyst was found. Salpingectomy was done as the tube was gangrenous. Conclusion. Fallopian tube torsion, though rare, should be considered in women of reproductive age with unilateral pelvic pain. Early diagnostic laparoscopy is important for an accurate diagnosis and could salvage the tube.

We describe a case of stump appendicitis with the formation of abdominal abscesses in a 41-year-old patient 10 years prior appendectomy. The patient consulted with fever (38.1 °C) and abdominal pain, located at the right iliac fossa. Imaging studies showed signs of abscesses, located at the right iliac fossa, without clear origin of these abscesses. The abscesses were drained through diagnostic laparoscopy, no bowel perforation or clear origin of the abscedation was found during laparoscopy. During postoperative stay, the inflammatory parameters rose and the abscesses reoccurred. Re-laparoscopy was performed, the abscesses were drained and on careful inspection and adhesiolysis, a perforated stump appendicitis was revealed, covered underneath layers of fibrous tissue. Stump appendicitis is a rare complication seen after appendectomy and is generally not considered a possible etiology in patients presenting with fever and right iliac fossa abdominal pain with a history of appendectomy. This often delays the correct diagnosis and results in an associated increased incidence of complications. We describe a case of stump appendicitis occurring 10 years after initial appendectomy.

Neonatal hemochromatosis is a rare metabolic disorder characterized by excessive iron deposition within the liver leading to hepatic failure and portal hypertension. We describe the clinical course and imaging findings in three infants with neonatal hemochromatosis associated with patent ductus venosus. We paid special attention to the diagnostic challenges encountered in these patients in order to emphasize some of the potential diagnostic pitfalls. We conducted a comprehensive search of our radiology database of the last 10 years (1999-2008) for the keywords ''neonatal hemochromatosis.'' Medical records and imaging studies of various modalities were reviewed. Three neonates were found to have neonatal hemochromatosis; all of them were associated with patent ductus venosus. Two of these patients were referred to our tertiary center for embolization of an inaccurately diagnosed hepatic vascular malformation. Two patients underwent successful liver transplantation and one died shortly after referral. The awareness and inclusion of neonatal hemochromatosis in the differential diagnosis of newborns with liver failure and patent ductus venosus has critical treatment implications. (orig.)

Background. Imaging of the abdomen in children with suspected hypertrophic pyloric stenosis has been traditionally performed by plain film radiography and upper gastrointestinal contrast studies. In many clinical situations, this approach has been modified or replaced by ultrasound examination. The authors aimed to analyse the value of diagnostic algorithm in children with hypertrophic pyloric stenosis confirmed at surgery in our hospital. Patients and methods. The authors made a five year retrospective review of hospital records of all children operated on for HPS in Clinical Hospital Centre Zagreb - Rebro and found out that 14 boys, between 2 (17 days) and 10 weeks of life (75 days) underwent surgery due to HPS. Results. Specific radiographic signs were: string sign, double track sign, elongation and narrowing of pyloric canal, mushroom sign, gastric distension with fluid and beak sign. Ultrasound was performed in 9 patients, one of them was false negative (sonographer admitted that he had no experience), the rest were positive. Conclusions. If the physical examination is negative or equivocal, sonography by an experienced sonographer must be performed. If the ultrasound finding is negative, than the infant should undergo to barium upper gastrointestinal studies (UGI). If HPS isn't a primary diagnostic question, it's better to perform UGI first in order to make a correct diagnosis. (author)

The purpose of this study was to define the limits of diagnostic glenohumeral arthroscopy and determine the prevalence and frequency of hidden extra-articular "bicipital tunnel" lesions among chronically symptomatic patients. Eight fresh-frozen cadaveric specimens underwent diagnostic glenohumeral arthroscopy with percutaneous tagging of the long head of the biceps tendon (LHBT) during maximal tendon excursion. The percentage of visualized LHBT was calculated relative to the distal margin of subscapularis tendon and the proximal margin of the pectoralis major tendon. Then, a retrospective review of 277 patients who underwent subdeltoid transfer of the LHBT to the conjoint tendon were retrospectively analyzed for lesions of the biceps-labral complex. Lesions were categorized by anatomic location (inside, junctional, or bicipital tunnel). Inside lesions were labral tears. Junctional lesions were LHBT tears visualized during glenohumeral arthroscopy. Bicipital tunnel lesions were extra-articular lesions hidden from view during standard glenohumeral arthroscopy. Seventy-eight percent of LHBT were visualized relative to the distal margin of the subscapularis tendon and only 55% relative to the proximal margin of the pectoralis major tendon. No portion of the LHBT inferior to the subscapularis tendon was visualized. Forty-seven percent of patients had hidden bicipital tunnel lesions. Scarring was most common and accounted for 48% of all such lesions. Thirty-seven percent of patients had multiple lesion locations. Forty-five percent of patients with junctional lesions also had hidden bicipital tunnel lesions. The only offending lesion was in the bicipital tunnel for 18% of patients. Diagnostic glenohumeral arthroscopy fails to fully evaluate the biceps-labral complex because it visualizes only 55% of the LHBT relative to the proximal margin of the pectoralis major tendon and did not identify extra-articular bicipital tunnel lesions present in 47% of chronically

Objective: To investigate MRI examination methods and imaging manifestations of primary ureteral carcinoma, and to evaluate its clinical values when comparing with other diagnostic imaging facilities. Methods: Eighty-seven cases of primary ureteral carcinoma who were operated within recent 8 years came into the study, among which, 35 cases had MRI examinations. For MRI examination, coronal heavy T 2 WI (water imaging) was performed to show the dilated ureter, then axial T 2 WI and T 1 WI were scanned at the obstruction level. 11 cases underwent additional Gd-DTPA dynamic contrast enhanced scans. The original pre-operative diagnostic reports of various imaging facilities were analyzed comparing with the results of operation and pathology. Results: MRI showed ureteral dilatation in 33 of 35 cases, no abnormal appearance in 1 case, and only primary kidney atrophy post renal transplantation in 1 case. Among the 33 cases with ureteral obstruction, soft mass at the obstruction level was detected on axial scans in 32 cases. The lesions showed gradual and homogeneous mild to moderate enhancement on contrast MRI. The overall employment rate of imaging facilities was as follows: ultrasound (94.3%), IVU (59.8%), CT (52.9%), MRI (40.2%), and RUP (35.6%). The accurate diagnostic rate was as follows :MRI (91.4%), RUP (80.6%), CT (63.0%), ultrasound (47.6%), and IVU (11.5%). Conclusion: Combination of MR water imaging and conventional sequences can demonstrate most primary ureteral carcinoma lesions and has a highest diagnostic accuracy among the current diagnostic imaging facilities. It should be taken as the first diagnostic imaging method of choice when primary ureteral carcinoma is suspected after ultrasound screening

To evaluate, in patients with hydrosalpinges, the effect on in vitro fertilization (IVF) outcome of the insertion by hysteroscopy of an intratubal blocking device, in cases where laparoscopic salpingectomy or laparoscopy was contraindicated. A prospective interventional case series study was conducted in fifteen women with unilateral (N=6) or bilateral hydrosalpinges (N=9) submitted for IVF. In all of them, laparoscopic salpingectomy was contraindicated. Hysteroscopic insertion of the Essure intratubal device in a consultation room setting was performed. IVF results were compared with those of women where hydrosalpinx was treated by laparoscopic salpingectomy (48 women, 76 cycles). There were no complications during or immediately after the procedure in any of the patients. There were four pregnancies from 16 embryo-transfers with own oocytes, one spontaneous pregnancy after unilateral Essure insertion, and one pregnancy after oocyte donation. In one case the hydrosalpinx grew and pelvic inflammatory disease developed 6 months after the insertion, requiring bilateral adnexectomy. Although not of statistical significance, IVF pregnancy rates were somewhat lower than in the laparoscopic salpingectomy group, which was attributed to the lower ovarian reserve before Essure insertion. The hysteroscopic insertion of the Essure intratubal device prior to IVF is a reasonable option in cases where laparoscopic salpingectomy is contraindicated. Larger series are required to assess pregnancy outcome. Copyright © 2013. Published by Elsevier Ireland Ltd.

The primary objective of this study was to evaluate the impact of polypharmacy on primary and secondary adherence to evidence-based medication (EBM) and to measure factors associated with non-adherence among patients who underwent percutaneous coronary intervention (PCI). We conducted a retrospective analysis for patients who underwent PCI at a tertiary cardiac care hospital in Qatar. Patients who had polypharmacy (defined as ≥6 medications) were compared with those who had no polypharmacy at hospital discharge in terms of primary and secondary adherence to dual antiplatelet therapy (DAPT), beta-blockers (BB), angiotensin converting enzyme inhibitors (ACEIs) and statins. A total of 557 patients (mean age: 53±10 years; 85%; males) who underwent PCI were included. The majority of patients (84.6%) received ≥6 medications (polypharmacy group) while only 15.4% patients received ≥5 medications (nonpolypharmacy group). The two groups were comparable in term of gender, nationality, socioeconomic status and medical insurance. The non-polypharmacy patients had significantly higher adherence to first refill of DAPT compared with patients in the polypharmacy group (100 vs. 76.9%; p=0.001). Similarly, the non-polypharmacy patients were significantly more adherent to secondary preventive medications (BB, ACEI and statins) than the polypharmacy group. In patients who underwent PCI, polypharmacy at discharge could play a negative role in the adherence to the first refill of EBM. Further studies should investigate other parameters that contribute to long term non-adherence.

O procedimento possibilitou inspeção dos órgãos e estruturas anatômicas localizados dorsalmente à direita da cavidade abdominal, favorecendo a escolha do local de biópsia hepática. Não foram observadas alterações no exame físico dos animais. Os exames hematológicos e de função hepática não apresentaram alterações significativas. Concluiu-se que o emprego da laparoscopia para realização de biópsia hepática em eqüino é simples, eficaz e seguro.The purpose of this research was to evaluate the use of laparoscopy in obtaining hepatic biopsy in horses and to determine a possible clinical and laboratorial changes related to the procedure. Ten animals were submitted to 36 hours of fastening and 18 hours of water deprivation and then operated in the standing position, through a right flank approach at the level of the 17th intercostal space. Post-operative evaluation consisted of daily physical examination and seriated blood sampling. The procedure allowed for wide visualization of the viscera and anatomical structures located on the right side of the abdominal cavity, favouring the choice of the spot for hepatic biopsy collection. No changes were noted in the physical state of the animals and alterations in hemogram and hepatic function tests were not statistically significant. It was concluded that laparoscopy is a simple, effective and safe technique for obtaining hepatic biopsy

Highlights: • The use of a color scale to display the non-contrast CT images in lieu of the classic grayscale improves the diagnostic confidence of the readers. • Radiologists should consider the use of a color scale, rather than the conventional grayscale, to assess non-contrast CT studies for possible carotid artery dissection. - Abstract: Purpose: The purpose of this work was to evaluate if the use of color maps, instead of conventional grayscale images, would improve the observer's diagnostic confidence in the non-contrast CT evaluation of internal carotid artery dissection (ICAD). Materials and methods: One hundred patients (61 men, 39 women; mean age, 51 years; range, 25–78 years), 40 with and 60 without ICAD, underwent non-contrast CT and were included in this the retrospective study. In this study, three groups of patients were considered: patients with MR confirmation of ICAD, n = 40; patients with MR confirmation of ICAD absence, n = 20; patients who underwent CT of the carotid arteries because of atherosclerotic disease, n = 40. Four blinded observers with different levels of expertise (expert, intermediate A, intermediate B and trainee) analyzed the non-contrast CT datasets using a cross model (one case grayscale and the following case using the color scale). The presence of ICAD was scored on a 5-point scale in order to assess the observer's diagnostic confidence. After 3 months the four observers evaluated the same datasets by using the same cross-model for the alternate readings (one case color scale and the following case using the grayscale). Statistical analysis included receiver operating characteristics (ROC) curve analysis, the Cohen weighted test and sensitivity, specificity, PPV, NPV, accuracy, LR+ and LR−. Results: The ROC curve analysis showed that, for all observers, the use of color scale resulted in an improved diagnostic confidence with AUC values increasing from 0.896 to 0.936, 0.823 to 0.849, 0.84 to 0.909 and 0

Aim: To evaluate the incidence and associated factors of postoperative intense pain and haemodynamic changes during radiofrequency ablation of hepatocellular carcinoma. Materials and methods: A total of 123 consecutive hepatocellular carcinoma patients who underwent radiofrequency ablation were prospectively recruited. Patient factors, tumour characteristics, procedural factors, intraoperative haemodynamic changes, complications, postoperative events, laboratory values before and after ablation, and postoperative pain were evaluated. Postoperative pain was scored using a visual analogue scale after the procedure. Results: The mean age of the patients was 65.6 ± 9.6 years. In multiple logistic regression analysis, patients who underwent general anaesthesia [odds ratio (95% CI): 2.68 (1.23–5.81); p = 0.013] and had more postoperative nausea and vomiting episodes [3.10 (1.11–8.63); p = 0.036] were associated with intense pain. These findings remain robust after propensity score matching. For mean difference values between before and after RFA, higher in change in aspartate transaminase (p = 0.026), alanine transaminase (p = 0.016) and white blood cell count (p = 0.015), and lower in change in haemoglobin (p = 0.009) were also correlated with intense pain. There was no significant difference in haemodynamic changes between the general anaesthesia and local anaesthesia group during ablation. Conclusion: General anaesthesia, postoperative nausea and vomiting, and laboratory factors were associated with postoperative intense pain in patients who underwent radiofrequency ablation. Counselling and modification of analgesics should be considered in patients with related factors for intense pain

The usefulness of single, random measurements of serum FSH and LH in the diagnosis of primary amenorrhea by radioimmunoassay was investigated. The 16 patients were divided into 3 groups by the level of serum FSH and LH. The first group with increased level of serum FSH and LH is five patients, all of these are related to the acquired or congenital abnormality of the ovary. Further studies indicated include buccal smear, chromosome analysis, gynecography and laparoscopy. The second group with normal serum FSH and LH is nine patients, four patients of these are related to the developmental anomaly of the Mullerian duct and five patients are undetermined origin. Further studies indicated include laparoscopy and gynecography. The third group with decreased serum FSH and normal or decreased serum LH is two patients, one of these is related to the pituitary function, isolated FSH deficiency, the other is undetermined origin. Further studies indicated include the pituitary function test, LH-RH stimulation test, skull radiography. Determination of serum FSH and LH levels does not permit a specific etiologic diagnosis of promary amenorrhea. However the serum levels of FSH and LH can be used to differentiate the principal area of the investigation and can be of assistance in choosing more specific testing procedures. (Author)

To compare the diagnostic performance of qualitative shear-wave elastography (SWE) according to three different color map opacities for breast masses 101 patients aged 21-77 years with 113 breast masses underwent B-mode US and SWE under three different color map opacities (50%, 19% and 100%) before biopsy or surgery. Following SWE features were reviewed: visual pattern classification (pattern 1-4), color homogeneity (Ehomo) and six-point color score of maximum elasticity (Ecol). Combined with B-mode US and SWE, the likelihood of malignancy (LOM) was also scored. The area under the curve (AUC) was obtained by ROC curve analysis to assess the diagnostic performance under each color opacity. A visual color pattern, Ehomo, Ecol and LOM scoring were significantly different between benign and malignant lesions under all color opacities (Pbreast lesion under all color opacities. The difference in color map opacity did not significantly influence diagnostic performance of SWE. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

The purpose of this study was to describe the laparoscopic approach to incarcerated inguinal hernia in children. After unsuccessful manual reduction, 29 patients (aged 3 weeks to 7 years; median, 10 weeks; 44 boys, 15 girls) with incarcerated inguinal hernia underwent immediate laparoscopy. The hernial content was reduced in a combined technique of external manual pressure and internal pulling by forceps. The bowel was inspected, and the hernia was repaired. In all patients, the procedure was successful. No conversion to the open approach was required. Immediate laparoscopic herniorrhaphy in the same session was added. No complications occurred. Laparoscopy allowed for simultaneous reduction under direct visual control, inspection of the incarcerated organ, and definitive repair of the hernia. Technically, it appears easier than the conventional approach because of the internal inguinal ring being widened by intraabdominal carbon dioxide insufflation. The hospital stay is shorter.

Several multi-institutional prospective randomized trials have demonstrated short-term benefits using laparoscopy. Now the laparoscopic approach is accepted as an alternative to open surgery for colon cancer. However, in prior trials, the transverse colon was excluded. Therefore, it has not been determined whether laparoscopy can be used in the setting of transverse colon cancer. This study evaluated the peri-operative clinical outcomes and oncological quality by pathologic outcomes of laparoscopic surgery for transverse colon cancer. Analysis of the medical records of patients who underwent laparoscopic colorectal resection from August 2004 to November 2007 was made. Computed tomography, barium enema, and colonoscopy were performed to localize the tumor preoperatively. Extended right hemicolectomy, transverse colectomy, and extended left hemicolectomy were performed for transverse colon cancer. Surgical outcomes and pathologic outcomes were compared between transverse colon cancer (TCC) and other site colon cancer (OSCC). Of the 312 colorectal cancer patients, 94 patients underwent laparoscopic surgery for OSCC, and 34 patients underwent laparoscopic surgery for TCC. Patients with TCC were similar to patients with OSCC in age, gender, body mass index, operating time, blood loss, time to pass flatus, start of diet, hospital stay, tumor size, distal resection margin, proximal resection margin, number of lymph nodes, and radial margin. One case in TCC and three cases in OSCC were converted to open surgery. Laparoscopic surgery for transverse colon cancer and OSCC had similar peri-operative clinical and acceptable pathological outcomes.

2012 HIV Diagnostic Conference Atlanta, GA, USA, 12-14 December 2012. This report highlights the presentations and discussions from the 2012 National HIV Diagnostic Conference held in Atlanta (GA, USA), on 12-14 December 2012. Reflecting changes in the evolving field of HIV diagnostics, the conference provided a forum for evaluating developments in molecular diagnostics and their role in HIV diagnosis. In 2010, the HIV Diagnostics Conference concluded with the proposal of a new diagnostic algorithm which included nucleic acid testing to resolve discordant screening and supplemental antibody test results. The 2012 meeting, picking up where the 2010 meeting left off, focused on scientific presentations that assessed this new algorithm and the role played by RNA testing and new developments in molecular diagnostics, including detection of total and integrated HIV-1 DNA, detection and quantification of HIV-2 RNA, and rapid formats for detection of HIV-1 RNA.

Signal intensity of lumbar-spine at magnetic resonance imaging (MRI) correlates to bone mineral density (BMD). Our aim was to define a quantitative MRI-based score to detect osteoporosis on lumbar-spine MRI. After Ethics Committee approval, we selected female patients who underwent both lumbar-spine MRI and dual-energy X-ray absorptiometry (DXA) and a reference group of 131 healthy females (20-29 years) who underwent lumbar-spine MRI. We measured the intra-vertebral signal-to-noise ratio in L1-L4. We introduced an MRI-based score (M-score), on the model of T-score. M-score diagnostic performance in diagnosing osteoporosis was estimated against DXA using receiver operator characteristic (ROC) analysis. We included 226 patients (median age 65 years), 70 (31 %) being osteoporotic at DXA. MRI signal-to-noise ratio correlated to BMD (r = -0.677, P < 0.001). M-score negatively correlated to T-score (r = -0.682, P < 0.001). Setting a 90 %-specificity, an M-score threshold of 5.5 was found, distinguishing osteoporosis from non-osteoporosis (sensitivity 54 %; ROC AUC 0.844). Thirty-one (14 %) patients had a fragility fracture, with osteoporosis detected in 15 (48 %) according to M-score and eight (26 %) according to T-score (P = 0.016). M-score obtained on lumbar spine MRI is a quantitative method correlating with osteoporosis. Its diagnostic value remains to be demonstrated on a large prospective cohort of patients. (orig.)

46,XY pure gonadal dysgenesis (Swyer syndrome) is characterized by normal female genitalia at birth. It usually first becomes apparent in adolescence with delayed puberty and amenorrhea. Rarely, patients can present with spontaneous breast development and/or menstruation. A fifteen-year-old girl presented to our clinic with the complaint of primary amenorrhea. On physical examination, her external genitals were completely female. Breast development and pubic hair were compatible with Tanner stage V. Hormonal evaluation revealed a hypergonadotropic state despite a normal estrogen level. Chromosome analysis revealed a 46,XY karyotype. Pelvic ultrasonography showed small gonads and a normal sized uterus for age. SRY gene expression was confirmed by multiplex polymerase chain reaction. Direct sequencing on genomic DNA did not reveal a mutation in the SRY, SF1 and WT1 genes. After the diagnosis of Swyer syndrome was made, the patient started to have spontaneous menstrual cycles and therefore failed to attend her follow-up visits. After nine months, the patient underwent diagnostic laparoscopy. Frozen examination of multiple biopsies from gonad tissues revealed gonadoblastoma. With this report, we emphasize the importance of performing karyotype analysis, which is diagnostic for Swyer syndrome, in all cases with primary or secondary amenorrhea even in the presence of normal breast development. We also suggest that normal pubertal development in patients with Swyer syndrome may be associated with the presence of a hormonally active tumor.

Laparoscopic Splenectomy for Traumatic Splenic Injury after Screening Colonoscopy

Full Text Available Colonoscopy is a widespread diagnostic and therapeutic procedure. The most common complications include bleeding and perforation. Splenic rupture following colonoscopy is rarely encountered and is most likely secondary to traction on the splenocolic ligament. Exploratory laparotomy and splenectomy is the most commonly employed therapeutic intervention for this injury reported in the literature. We present the case of a patient with this potentially fatal complication who was treated successfully at our institution. To our knowledge it is the first report in the literature of laparoscopic splenectomy as a successful minimally invasive treatment of splenic rupture following colonoscopy. The patient was a 62-year-old female who underwent screening colonoscopy with polypectomies at the cecum, descending colon and rectum. Immediately following the procedure she developed abdominal pain and had a syncopal episode. Clinical, laboratory and imaging findings were suggestive of hemoperitoneum and a ruptured spleen. A diagnostic laparoscopy was emergently performed and revealed a grade IV splenic laceration and hemoperitoneum. Laparoscopic splenectomy was completed safely and effectively. The patient’s postoperative recovery was uneventful. We conclude that splenic rupture after colonoscopy is a rare but dangerous complication. A high index of suspicion is required to recognize it early. Awareness of this potential complication can lead to optimal patient outcome. Laparoscopic splenectomy may be a feasible treatment option.

The diagnostic work-up in patients with fever of unknown origin (FUO) is often challenging and frequently includes nuclear medicine procedures. Whereas a role for leucocyte or granulocyte scintigraphy in FUO is generally accepted, a possible role of fluorine-18 fluorodeoxyglucose (FDG) positron...... emission tomography (PET) in these patients remains to be established. To study this, we compared prospectively, on a head-to-head basis, the diagnostic value of FDG-PET and indium-111 granulocyte scintigraphy in patients with FUO. Nineteen patients with FUO underwent both FDG-PET and (111)In......-granulocyte scintigraphy within 1 week. FDG-PET scans and granulocyte scintigrams were reviewed by different doctors who were blinded to the result of the other investigation. The diagnostic values of FDG-PET and granulocyte scintigraphy were evaluated with regard to identification of a focal infectious...

Few diagnostic biomarkers for sepsis after emergency peritonitis surgery are available to clinicians, and, thus, it is important to develop new biomarkers for patients undergoing this procedure. We investigated whether serum glutamine and selenium levels could be diagnostic biomarkers of sepsis in individuals recovering from emergency peritonitis surgery. From February 2012 to March 2013, patients who had peritonitis diagnosed at the emergency department and underwent emergency surgery were screened for eligibility. Serum glutamine and selenium levels were obtained at pre-operative, post-operative and recovery time points. The average level of pre-operation serum glutamine was significantly different from that on the recovery day (0.317 ± 0.168 vs. 0.532 ± 0.155 mM, P peritonitis. We recommend including glutamine as a biomarker for sepsis severity assessment in addition to the commonly used clinical indicators.

We performed a study of 448 women with breast cancer who visited the breast clinic of Nagano Cancer Center, and underwent mammography (MMG) and ultrasonography (US) at the last examination, between October 1983 and December 1993. These women subsequently underwent surgery at several hospitals after referral from our center. Definitive diagnoses of breast cancer were made histopathologically. Both MMG and US findings were graded using five-step criteria (indicating the level of malignancy) from I (normal) to V (definite malignancy). The diagnostic efficiencies of the two examinations were then compared clinicopathologically. Furthermore, on the basis of the results obtained, we considered supplemental diagnostic methods that could be introduced for mass screening of breast cancer. There was a significant difference between the incidence of cases diagnosed as V IV III b (malignancy) by US (71.9%) and those diagnosed by MMG (60.9%). Among cases suspected to be breast cancer by palpation, the proportion diagnosed as V IV III b (malignancy) by US (83.3%) was significantly higher than that diagnosed by MMG (73.7%). Among cases suspected to be mastopathy by palpation, the proportion diagnosed as malignant by US was higher than that diagnosed by MMG. The false negativity rate for palpation combined with MMG was higher than that for palpation with US. Among cases without palpable masses, the proportion diagnosed as malignant by MMG was higher than that diagnosed by US. However, for palpable tumors less than 5.0 cm in diameter, the proportion of cases diagnosed as malignant by US was higher than that diagnosed by MMG. In terms of the gross appearance of the cut surface, grade of cancer invasion, histological type and grade of chubbiness, the diagnostic efficiency of US was shown to be slightly better than that of MMG. The above results suggest that US should be considered as a supplemental method for introduction to mass screening of breast cancer. (author)

The diagnosis of subacromial pathology is limited by the poor accuracy of clinical tests for specific pathologies. The aim of this study was to estimate the diagnostic accuracy of clinical examination and imaging features for identifying subacromial pain (SAP) defined by a positive response to diagnostic injection, and to evaluate the influence of imaging findings on the clinical diagnosis of SAP. In a prospective, diagnostic accuracy design, 208 consecutive patients presenting to their primary healthcare practitioner for the first time with a new episode of shoulder pain were recruited. All participants underwent a standardized clinical examination, shoulder x-ray series and diagnostic ultrasound scan. Results were compared with the response to a diagnostic block of xylocaineTM injected into the SAB under ultrasound guidance using ≥80% post-injection reduction in pain intensity as the positive anaesthetic response (PAR) criterion. Diagnostic accuracy statistics were calculated for combinations of clinical and imaging variables demonstrating the highest likelihood of a PAR. A PAR was reported by 34% of participants. In participants with no loss of passive external rotation, combinations of three clinical variables (anterior shoulder pain, strain injury, absence of symptoms at end-range external rotation (in abduction)) demonstrated 100% specificity for a PAR when all three were positive (LR+ infinity; 95%CI 2.9, infinity). A full-thickness supraspinatus tear on ultrasound increased the likelihood of a PAR irrespective of age (specificity 98% (95%CI 94, 100); LR+ 6.2; 95% CI 1.5, 25.7)). Imaging did not improve the ability to rule-out a PAR. Combinations of clinical examination findings and a full-thickness supraspinatus tear on ultrasound scan can help confirm, but not exclude, the presence of subacromial pain. Other imaging findings were of limited value for diagnosing SAP.

To know what is the meaning of non-diagnostic results of fine needle aspiration biopsy (FNAB) and whether repeated aspiration is needed or not in those situations. We reviewed 1845 patients who underwent FNAB from 1997 to 2001. Non-diagnostic results of the first FNAB were divided into four groups: insufficient number of cells, inflammatory cells, necrotic debris and atypical cells. We analyzed final diagnosis of 531 patients who had non-diagnostic results from the first FNAB. Among them, 207 lesions were re-biopsied because of clinical and radiologic suspicion of malignancy. The diagnostic yield of repeated FNAB was analyzed and compared with the results of the first FNAB. Among 255 cases with 'inflammatory cells only' results, 120 cases were confirmed benignancy on follow-up. Twenty nine of 50 stypical cells (58%) were malignant of follow-up. One hundred one of 207 repeated FNAB resulted in the non-diagnostic reports, and 106 of 207 repeated FNAB were diagnosed as specific diagnosis. Among thirty lesions showing atypical cells on the repeated FNAB, 22 (73%) were identified as malignant neoplasms. When the specimen of FNAB shows atypical cells, the possibility of malignancy is very high. When the results of FNAB is non-diagnostic in the cases with clinical and radiological suspicion of malignancy, repeated FNAB procedures should be seriously considered and will be helpful for accurate specific diagnosis

We aimed to evaluate the diagnostic values of conventional ultrasound (US), ultrasound contrast (UC) and ultrasound elastography (UE) in distinguishing the benign and malignant thyroid nodules. A total of 100 patients with thyroid nodules receiving operative treatment were selected; they underwent the conventional US, UE and UC examinations before operation, respectively. The nodules received pathological examination after operation to distinguish benign from malignant lesions. The sensitivity, specificity and diagnostic accordance rate of each diagnostic method was evaluated by receiver operating characteristic (ROC) curve, and the area under the curve (AUC) of ROC was calculated. The manifestations of malignant thyroid nodules in conventional US examination were mostly the hypoecho, heterogeneous echo, irregular shape, unclear boundary, aspect ratio benign and malignant nodules in 2, 3 and 4 points were statistically significant (Pbenign and malignant thyroid nodules.

To investigate the expression of capsaicin receptor (transient receptor potential vanilloid type 1 [TRPV1]) in the peritoneal endometriosis foci of women with and without chronic pelvic pain (CPP). A case-control study was conducted on 49 women with endometriosis who underwent laparoscopy, 28 of whom had CPP and 21 without CPP. Samples from peritoneum of the rectouterine excavation (2 cm2) were obtained by laparoscopy, fixed in 4% formaldehyde, and underwent immunohistochemistry analysis using rabbit anti-TRPV1 (1:400) polyclonal antibody. Image analysis revealed that the immunoreactivity for TRPV1 was more frequent in specimens (endometriosis foci) from women with CPP (n = 15 of 28, 53.6%), compared to samples from the endometriosis foci of women without CPP (n = 6 of 21, 28.6%; P = .04). There was no correlation with duration, intensity of pain, or stage of the disease (endometriosis). The present study shows that TRPV1 expression in peritoneal endometriosis foci is related to CPP in women. However, this association is not related to the endometriosis stage. In view of the immunoreactivity for TRPV1 observed here, we believe that some endometriotic lesions may provide a scenario for TRPV1 to be tonically active and this activity may contribute to the underlying pathology of CPP.

This study evaluated the short- and long-term outcomes of laparoscopic colectomy compared with open colectomy for patients with transverse colon cancer by matched-pair analysis. This study enrolled 59 patients who underwent laparoscopic colectomy and compared them with 59 matched patients who underwent open colectomy for transverse colon cancer. The following parameters were matched: clinical stage and type of resection. Both short- and long-term outcomes of laparoscopic colectomy were compared with those of open colectomy. No difference was observed between the two groups in terms of age, gender, ASA score, comorbidity, clinical stage and operative procedures. Regarding short-term outcomes, blood loss, time to first flatus, time to liquid diet and postoperative stay were significantly shorter in the laparoscopy group than in the open group, while operation time was significantly longer in the laparoscopy group than in the open group. Postoperative complication was similar between the two groups. With respect to long-term outcomes, the two groups did not differ significantly in terms of 5-year overall and disease-free survival. In summary, laparoscopic colectomy is a safe and feasible option for selected patients with transverse colon cancer. The short- and long-term outcomes of laparoscopic colectomy are considered to be acceptable.

A 67-year-old man was referred to our attention for management of esophageal adenocarcinoma, localized at the level of the esophagogastric junction and obstructed the 1/3 of the esophageal lumen. Due to the extension of the disease (T3N1M0-Stage IIIA), the patient underwent neo-adjuvant chemo-radiation therapy and he was then scheduled for a minimally invasive surgical procedure including laparoscopic gastroplasty, uniportal thoracoscopic esophageal dissection and intrathoracic end-to-end esophago-gastric anastomosis. No intraoperative and post-operative complications were seen. The patient was discharged in post-operative day 9. Pathological study confirmed the diagnosis of adenocarcinoma (T2N1M0-Stage IIB) and he underwent adjuvant chemotherapy. At the time of present paper, patient is alive and well without signs of recurrence or metastasis. Our minimally approach compared to standard open procedure would help reduce post-operative pain and favours early return to normal activity. However, future experiences with a control group are required before our strategy can be widely used.

Objective To evaluate the diagnostic accuracy of the 2011 International Federation for Cervical Pathology and Colposcopy (IFCPC) colposcopic terminology. Methods The clinicopathological data of 2262 patients who underwent colposcopy from September 2012 to September 2016 were reviewed. The colposcopic findings, colposcopic impression, and cervical histopathology of the patients were analyzed. Correlations between variables were evaluated using cervical histopathology as the gold standard. Results Colposcopic diagnosis matched biopsy histopathology in 1482 patients (65.5%), and the weighted kappa strength of agreement was 0.480 (Pterminology can improve the diagnostic accuracy for all lesion severities. The categorization of major changes and minor changes is appropriate. However, colposcopic diagnosis remains unsatisfactory. Poor reproducibility of type 2 transformation zone and the significance of leukoplakia require further study. PMID:29507681

Abstract Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital coronary abnormality associated with early infant mortality and sudden death in adults. Transthoracic echocardiography (TTE) plays an important role in early detection and diagnosis of ALCAPA as a noninvasive modality. However, its diagnostic value is not well studied. The purpose of this study is to determine the performance of TTE in the diagnostic assessment of ALCAPA as compared with coronary CT and invasive coronary angiography. A total of 22 patients (13 women and 9 men, mean age, 12.9 ± 19.5 years) with ALCAPA who underwent echocardiographic examination for clinical diagnosis were retrospectively reviewed and analyzed. Transthoracic echocardiographic features of ALCAPA were analyzed and its diagnostic value was compared with invasive coronary angiography and coronary CT angiography (CTA) with surgical findings serving as the gold standard. Surgery was performed in all of the patients to establish the dual coronary artery system. Five underwent the Takeuchi procedure and 17 had re-implantation of the anomalous left coronary artery. Of 20 patients, echocardiographic diagnoses were in good agreement with findings at surgery, resulting in the diagnostic accuracy of 90.9%. Two cases were misdiagnosed—one as the right coronary artery to pulmonary artery fistula and the other as rheumatic heart disease. The echocardiographic features of these patients with ALCAPA included: abnormal left coronary ostium arising from the pulmonary trunk with retrograde coronary artery flow in 20 patients; enlargement of the right coronary artery in 17 patients; abundant intercoronary septal collaterals in 17 patients; and moderate and significant mitral regurgitation in 14 patients. The diagnostic accuracy of invasive coronary angiography (in 17 patients) and coronary CTA (in 9 patients) was 100%. This study shows that TTE is an accurate, noninvasive imaging modality

Full Text Available Introduction: The added diagnostic value of 11C-PiB-PET for the assessment of the accumulation of cortical beta-amyloid in memory clinic patients with uncertain diagnosis remains undetermined. Methods: All patients who underwent PiB-PET at the Copenhagen Memory Clinic between March 2008 and November 2011 were included in this uncontrolled, retrospective study. The standard diagnostic evaluation program included physical and neurological examination, cognitive and functional assessment, a cranial CT or MRI, functional imaging and cerebrospinal fluid sampling. Based on anonymized case reports, three experienced clinicians reached a consensus diagnosis and rated their confidence in the diagnosis before and after disclosure of PiB-PET ratings. PiB-PET scans were rated as either positive or negative. Results: A total of 57 patients (17 females, 30 males; age 65.7 years, range 44.2–82.6 were included in the study. Twenty-seven had a positive PiB-PET scan. At the first diagnostic evaluation, 16 patients were given a clinical Alheimer’s disease diagnosis (14 PiB positive. Of the 57 patients, 13 (23% were diagnostically reclassified after PiB-PET ratings were disclosed. The clinicians’ overall confidence in their diagnosis increased in 28 (49% patients. Conclusion: PiB-PET adds to the specialist clinical evaluation and other supplemental diagnostic investigations in the diagnostic classification of patients with uncertain diagnosis in a specialized memory clinic.

Amyotrophic lateral sclerosis (ALS) is an insidious, clinically heterogeneous neurodegenerative disease associated with a diagnostic delay of approximately 12 months. No study conducted to date has analysed the diagnostic pathway in Spain. We gathered data on variables related to the diagnostic pathway and delay for patients diagnosed with ALS between October 2013 and July 2017. The study included 143 patients with ALS (57% men; 68% spinal onset). Patients were diagnosed in public centres in 86% of cases and in private centres in 14%.The mean diagnostic delay was 13.1 months (median 11.7). Patients were examined by neurologists a mean time of 7.9 months after symptom onset, with diagnosis being made 5.2 months later. Half of all patients underwent unnecessary diagnostic tests and multiple electrophysiological studies before diagnosis was established. Diagnostic delay was longer in cases of spinal onset (P = .008) due to onset of the disease in the lower limbs. No differences were found between the public and private healthcare systems (P = .897). The diagnostic delay in ALS in Spain is similar to that of neighboring countries and seems to depend on disease-related factors, not on the healthcare system. Patients with lower-limb onset ALS constitute the greatest diagnostic challenge. Misdiagnosis is frequent, and partly attributable to an incorrect approach or erroneous interpretation of electrophysiological studies. Specific training programmes for neurologists and general neurophysiologists and early referral to reference centers may help to reduce diagnostic delay.

To evaluate the diagnostic accuracy of multidetector CT (MDCT) for detection of lumbar disc herniation with MRI as standard of reference. Patients with low back pain underwent indicated MDCT (128-row MDCT, helical pitch), 60 patients with iterative reconstruction (IR) and 67 patients with filtered back projection (FBP). Lumbar spine MRI (1.5 T) was performed within 1 month. Signal-to-noise ratios (SNR) of cerebrospinal fluid (CSF), annulus fibrosus (AF) and the spinal cord (SC) were determined for all modalities. Two readers independently rated image quality (IQ), diagnostic confidence and accuracy in the diagnosis of lumbar disc herniation using MRI as standard of reference. Inter-reader correlation was assessed with weighted κ. Sensitivity, specificity, precision and accuracy of MDCT for disc protrusion were 98.8%, 96.5%, 97.1%, 97.8% (disc level), 97.7%, 92.9%, 98.6%, 96.9% (patient level). SNR of IR was significantly higher than FBP. IQ was significantly better in IR owing to visually reduced noise and improved delineation of the discs. κ (>0.90) was excellent for both algorithms. MDCT of the lumbar spine yields high diagnostic accuracy for detection of lumbar disc herniation. IR improves image quality so that the provided diagnostic accuracy is principally equivalent to MRI.

To identify the distribution and frequency of computed tomography (CT) findings in patients with nosocomial rapidly growing mycobacterial (RGM) infection after laparoscopic surgery. A descriptive retrospective study in patients with RGM infection after laparoscopic surgery who underwent CT imaging prior to initiation of therapy. The images were analyzed by two radiologists in consensus, who evaluated the skin/subcutaneous tissues, the abdominal wall, and intraperitoneal region separately. The patterns of involvement were tabulated as: densification, collections, nodules (≥1.0 cm), small nodules (<1.0 cm), pseudocavitated nodules, and small pseudocavitated nodules. Twenty-six patients met the established criteria. The subcutaneous findings were: densification (88.5%), small nodules (61.5%), small pseudocavitated nodules (23.1 %), nodules (38.5%), pseudocavitated nodules (15.4%), and collections (26.9%). The findings in the abdominal wall were: densification (61.5%), pseudocavitated nodules (3.8%), and collections (15.4%). The intraperitoneal findings were: densification (46.1%), small nodules (42.3%), nodules (15.4%), and collections (11.5%). Subcutaneous CT findings in descending order of frequency were: densification, small nodules, nodules, small pseudocavitated nodules, pseudocavitated nodules, and collections. The musculo-fascial plane CT findings were: densification, collections, and pseudocavitated nodules. The intraperitoneal CT findings were: densification, small nodules, nodules, and collections. • Rapidly growing mycobacterial infection may occur following laparoscopy. • Post-laparoscopy mycobacterial infection CT findings are densification, collection, and nodules. • Rapidly growing mycobacterial infection following laparoscopy may involve the peritoneal cavity. • Post-laparoscopy rapidly growing mycobacterial intraperitoneal infection is not associated with ascites or lymphadenopathy.

Changing the Learning Curve in Novice Laparoscopists: Incorporating Direct Visualization into the Simulation Training Program.

A major challenge in laparoscopic surgery is the lack of depth perception. With the development and continued improvement of 3D video technology, the potential benefit of restoring 3D vision to laparoscopy has received substantial attention from the surgical community. Despite this, procedures conducted under 2D vision remain the standard of care, and trainees must become proficient in 2D laparoscopy. This study aims to determine whether incorporating 3D vision into a 2D laparoscopic simulation curriculum accelerates skill acquisition in novices. Postgraduate year-1 surgical specialty residents (n = 15) at the Schulich School of Medicine and Dentistry, at Western University were randomized into 1 of 2 groups. The control group practiced the Fundamentals of Laparoscopic Surgery peg-transfer task to proficiency exclusively under standard 2D laparoscopy conditions. The experimental group first practiced peg transfer under 3D direct visualization, with direct visualization of the working field. Upon reaching proficiency, this group underwent a perceptual switch, changing to standard 2D laparoscopy conditions, and once again trained to proficiency. Incorporating 3D direct visualization before training under standard 2D conditions significantly (p learning curves for each respective training protocol. An adaptive learning approach, which incorporates 3D direct visualization into a 2D laparoscopic simulation curriculum, accelerates skill acquisition. This is in contrast to previous work, possibly owing to the proficiency-based methodology employed, and has implications for resource savings in surgical training. Crown Copyright © 2016.

Aim: To assess the diagnostic accuracy of computed tomography coronary angiography (CTCA) using a combination of high-definition CT (HD-CTCA) and high level of reader experience, with invasive coronary angiography (ICA) as the reference standard, in high-risk patients for the investigation of coronary artery disease (CAD). Materials and methods: Three hundred high-risk patients underwent HD-CTCA and ICA. Independent experts evaluated the images for the presence of significant CAD, defined primarily as the presence of moderate (≥50%) stenosis and secondarily as the presence of severe (≥70%) stenosis in at least one coronary segment, in a blinded fashion. HD-CTCA was compared to ICA as the reference standard. Results: No patients were excluded. Two hundred and six patients (69%) had moderate and 178 (59%) had severe stenosis in at least one vessel at ICA. The sensitivity, specificity, positive predictive value, and negative predictive value were 97.1%, 97.9%, 99% and 93.9% for moderate stenosis, and 98.9%, 93.4%, 95.7% and 98.3%, for severe stenosis, on a per-patient basis. Conclusion: The combination of HD-CTCA and experienced readers applied to a high-risk population, results in high diagnostic accuracy comparable to ICA. Modern generation CT systems in experienced hands might be considered for an expanded role. - Highlights: • Diagnostic accuracy of High-Definition CT Angiography (HD-CTCA) has been assessed. • Invasive Coronary angiography (ICA) is the reference standard. • Diagnostic accuracy of HD-CTCA is comparable to ICA. • Diagnostic accuracy is not affected by coronary calcium or stents. • HD-CTCA provides a non-invasive alternative in high-risk patients.

Diagnosis of wrist pain can be difficult to determine with clinical examination and conventional imaging techniques alone. Bone SPECT-CT (single-photon emission tomography with computerized tomography) is a hybrid imaging technique that overlays functional bone scintigraphy in tomographic/3D mode with conventional CT. Data from the two modalities are complementary; areas of abnormal bone metabolism can be localized with anatomical precision, hitherto lacking in conventional bone scans, while structural information from the CT scan further embellishes the diagnostic information. Over the last 6 years, one surgeon (David Evans) has used bone SPECT and later bone SPECT-CT as an additional line of investigation. This is a series of 21 consecutive patients with wrist pain that could not be diagnostically resolved with the usual combination of history, examination, and conventional imaging, and therefore underwent bone SPECT-CT. Clinical and imaging findings, management, and outcomes of these cases are discussed to explore the potential role of this hybrid functional modality in hand and wrist surgical practice.

Neonatal hemochromatosis is a rare metabolic disorder characterized by excessive iron deposition within the liver leading to hepatic failure and portal hypertension. We describe the clinical course and imaging findings in three infants with neonatal hemochromatosis associated with patent ductus venosus. We paid special attention to the diagnostic challenges encountered in these patients in order to emphasize some of the potential diagnostic pitfalls. We conducted a comprehensive search of our radiology database of the last 10 years (1999-2008) for the keywords ''neonatal hemochromatosis.'' Medical records and imaging studies of various modalities were reviewed. Three neonates were found to have neonatal hemochromatosis; all of them were associated with patent ductus venosus. Two of these patients were referred to our tertiary center for embolization of an inaccurately diagnosed hepatic vascular malformation. Two patients underwent successful liver transplantation and one died shortly after referral. The awareness and inclusion of neonatal hemochromatosis in the differential diagnosis of newborns with liver failure and patent ductus venosus has critical treatment implications. (orig.)

Objective: To examine the potential utility of 3D-reconstructed sonograms to distinguish cirrhotic from non-cirrhotic livers by demonstrating hepatic surface characteristics. Materials and methods: A preliminary phantom study was performed to examine the potential resolution of 3D images, recognizing surface irregularities as a difference in height. In a prospective clinical study of 31 consecutive patients with ascites (21 cirrhosis, 10 non-cirrhosis), liver volume data were acquired by transabdominal mechanical scanning. The hepatic surface features of cirrhotic and non-cirrhotic patients were compared by 2 independent reviewers. Intra- and inter-operator/reviewer agreements were also examined. Results: The phantom study revealed that 0.4 mm was the minimum recognizable difference in height on the 3D sonograms. The hepatic surface image was successfully visualized in 74% patients (23/31). Success depended on the amount of ascites; visualization was 100% with ascites of 10 mm or more between the hepatic surface and abdominal wall. The images showed irregularity of the hepatic surface in all cirrhotic patients. The surface appearance was confirmed as being very similar in 3 patients who had both 3D sonogram and liver resection for transplantation. The ability to distinguish cirrhotic liver from non-cirrhotic liver improved with the use of combination of 2D- and 3D-imaging versus 2D-imaging alone (sensitivity, p = 0.02; accuracy, p = 0.02) or 3D-imaging alone (sensitivity, p = 0.03). Intra-/inter-operator and inter-reviewer agreement were excellent (κ = 1.0). Conclusion: 3D-based sonographic visualization of the hepatic surface showed high reliability and reproducibility, acting as a virtual laparoscopy method, and the technique has the potential to improve the diagnosis of cirrhosis

Gastrofiberscopy as well as roentgenologic examination of stomach, is now considered to be one of the indispensable diagnostic method of gastric disease. In general it is agreed that the roentgenologic examination is convenient for observation of shape, contour, motor function and gross lesion of stomach white gastrofiberscopy is especially valuable in detection of mucosal changes or small lesions of stomach. For evaluation of gastrofiberscopy in the diagnosis of various gastric diseases, the diagnostic accuracy of gastrofiberscopy was studied in 964 cases who underwent the fiberscopic examination in SNUH during the period from March 1, 1968 till April 30, 1971. The following results were obtained. 1. Each fiberscopic diagnosis in the 964 cases was classified as follows: normal stomach 414 cases (42.9%), gastritis 74 cases (7.7%), gastric ulcer 134 cases (13.9%), healed ulcer 14 cases (1.5%), benign pyloric stenosis 15 cases (1.6%), suspicious duodenal ulcer 23 cases (2.4%), gastric polyp 6 cases (0.6%), leiomyoma 1 case (0.1%), bezoar 2 cases (0.2%), xanthoma 1 case (0.1%), gastric carcinoma 237 case (24.6%), extrinstic mass 1 case (0.1%), post-operative condition 9 cases (0.9%), unsatisfactory examination 31 cases (3.2%), indeterminate diagnosis 2 cases (0.2%). 2. In various gastric diseases, the coincidence rate of diagnosis between fiberscopic and roentgenologic examination was studied and the obtained results are as follows: in normal stomach 72.9% (302/414), gastric ulcer 69.4% (93/134), healed ulcer 42.9% (6/14), benign pyloric stenosis 86.7% (13/15), duodenal ulcer 100.0% (23/23), gastric polyp 66.7% (4/6), gastric carcinoma 87.8% (208/237), post operative condition 66.7% (6/9). The overall result shows that the diagnostic coincidence between the two methods was observed in 67.7% of the cases (653/964). 3. The diagnostic accuracy of fiberscopic examination was 85.7% (24/28) in the diagnosis of gastric ulcer, 75.0% (6/8) in the diagnosis of benign pyloric

Objective: To study the various causes of female infertility, diagnosed at laparoscopy. Study Design: Descriptive study. Place and Duration of Study: The study was conducted at Military Hospital Rawalpindi, Pakistan from April 2008 to December 2010. Patients and Methods: A series of 186 patients, having either primary or secondary infertility admitted through gynae outpatient department undergoing diagnostic laparoscopy and meeting inclusion criteria were studied. The data was collected prospectively and analysed in the form of frequency and percentages by using SPSS version 10. Results: Amongst the cohort of 186 patients, 148 (79.6%) had primary and 38 (20.4%) had secondary infertility. Their ages ranged from 20 to 43 years. Mean age of study participants was 30.14 +- 4.04 years. Mean duration of infertility was 9.5 years. No laparoscopic abnormality was found in 51 (27.9%), while there were abnormal findings in 135 (72.6%) patients. Conclusion: Commonest etiological factor was tubal blockade in both types of infertility. Other factors were endometriosis, pelvic adhesions and fibroids. Laparoscopy is minimally invasive yet a reliable procedure for visualization of internal architecture of the female pelvis. (author)

Full Text Available Background: The aim of the study was to determine the correlation between clinical and echocardiographic findings and risk factors of patients with suspected acute pulmonary thromboembolism (PTE who underwent computed tomography pulmonary angiography (CTPA. Materials and Methods: In this cross-sectional study, 310 hospitalized patients aged >18 years with high clinical suspicion of PTE referred to imaging center of our hospital from different wards for CTPA were enrolled. The frequency of different clinical presentations, risk factors, items of Wells' criteria, and echocardiographic findings was compared in patients with and without PTE, which have been diagnosed according to the CTPA results. Results: PTE was diagnosed in 53 (17.1% of patients with suspected PTE. From clinical manifestations, tachypnea, pleuritic chest pain, and edema of lower extremities were significantly more frequent among patients with PTE (P < 0.05. Major surgery was the risk factor which was significantly more prevalent among patients with PTE (P < 0.05. Frequency of all criteria of Wells' criteria, except hemoptysis, was significantly higher in patients with PTE (P < 0.05. The frequency of all studied echocardiographic variables was significantly higher in patients with PTE (P < 0.05. Conclusion: It is suggested that we could use the results of this study for utilizing the diagnostic process of PTE in patients with highly clinical suspicion of PTE and providing more validated decision. Using the results of this study, we could identify high-risk patients and made appropriate risk assessment for better management of patients with suspected PTE as well as reduce the rate of unnecessary CTPA and its related adverse consequences.

We tested our laparoscopy-assisted "open" ligation (LOL) technique on testicular vessels. We ligated the left testicular artery and vein (TAV) in 8-week-old male Wister rats using LOL (LOL group; n=10) or laparotomy (open group; n=10). In LOL, a 0-degree laparoscope was introduced through a 5-mm epigastric trocar. A 3-mm grasper was used to expose the left TAV. A lapa-her-closure (LHC) needle loaded with 3-0 SurgiPro was directly inserted into the left lower quadrant where the left TAV should be and advanced under the vessels, and the suture material was released leaving one end outside. The LHC was then withdrawn a little and advanced again over the vessels to grasp the end of the suture material just released to bring it outside. This was proximally repeated. The two ends of both sutures were conventionally tied outside, and the knot was passed through the insertion site and tightened around the vessels. In the open group, the left TAV were ligated using two 3-0 SurgiPro ties. In both groups, the right side was left intact. All rats were sacrificed 2 weeks postoperatively, and both testes were examined with hematoxylin and eosin. Treatment time was 5-7 minutes for LOL and 7-8 minutes for the open group. Postoperative recovery was uneventful. No adhesions were present between the ligated vessels and bowel in any rat. Histopathology of all left testes showed coagulative necrosis of germinal cells and seminiferous tubules; all right testes were normal. LOL appears to be as effective as open ligation and may find application for treating varicocele.

Synchronized multiple regression of diagnostic radiation-induced rather than spontaneous: disseminated primary intracranial germinoma in a woman: a case report

Full Text Available Abstract Introduction Examples of the spontaneous regression of primary intracranial germinomas can be found in the literature. We present the case of a patient with disseminated lesions of primary intracranial germinoma which synchronously shrunk following diagnostic irradiation. We will discuss whether this regression was spontaneous or radiation-induced. Case presentation A 43-year-old Japanese woman presented to our hospital complaining of memory problems over a period of one year and blurred vision over a period of three months. Following magnetic resonance imaging, she was found to have a massive lesion in the third ventricle and small lesions in the pineal region, fourth ventricle, and in the anterior horn of the left lateral ventricle. Prior to an open biopsy to confirm the pathology of the lesions, she underwent a single cranial computed tomography scan and a single cranial digital subtraction angiography for a transcranial biopsy. Fourteen days after the first magnetic resonance image - 12 and eight days after the computed tomography scan and digital subtraction angiography, respectively - a pre-operative magnetic resonance image was taken, which showed a notable synchronous shrinkage of the third ventricle tumor, as well as shrinkage of the lesions in the pineal region and in the fourth ventricle. She did not undergo steroid administration until after a biopsy that confirmed the pathological diagnosis of pure germinoma. She then underwent whole craniospinal irradiation and went into a complete remission. Conclusions In our case report, we state that diagnostic radiation can induce the regression of germinomas; this is the most reasonable explanation for the synchronous multiple regression observed in this case of germinoma. Clinicians should keep this non-spontaneous regression in mind and monitor germinoma lesions with minimal exposure to diagnostic radiation before diagnostic confirmation, and also before radiation treatment with or

The aim of this study is to determine whether simulation-based education (SBE) translates into reduced procedure time, radiation, and contrast use in actual clinical care. As a high volume procedure often performed by novice cardiology fellows, diagnostic coronary angiography represents an excellent target for SBE. Reports of SBE in interventional cardiology are limited and there is little understanding of the potential downstream clinical impact of these interventions. All diagnostic coronary angiograms performed at a single center between January 1, 2011 and June 30, 2015 were analyzed. Random effects linear regression models were used to compare outcomes between procedures performed by 12 cardiology fellows who underwent simulation-based training and those performed by 20 traditionally trained fellows. Thirty-two cardiology fellows performed 2,783 diagnostic coronary angiograms. Procedures performed by fellows trained with SBE were shorter (mean of 23.98 min vs. 24.94 min, P = 0.034) and were performed with decreased radiation (mean of 56,348 mGycm 2 vs. 66,120 mGycm 2 , P < 0.001). After controlling for year in training, procedure year, access site, and supervising attending physician, training on the simulator was independently associated with 117 fewer seconds of fluoroscopy time per procedure (P = 0.04). Diagnostic coronary angiography SBE is associated with decreased use of fluoroscopy in downstream clinical care. SBE may be a useful tool to reduce radiation exposure in the cardiac catheterization laboratory. © 2017 Wiley Periodicals, Inc.

Full Text Available Background and Objective: Advances in laparoscopy are making the service accessible even in resource-poor countries where adaptations are made to meet local challenges. We report our experience in the provision of laparoscopy service to children at a tertiary health center in North-central Nigeria. Methods: A team of pediatric surgeons, anesthetists, and nurses collaborated to provide service and train other personnel. A prospective collection of data on biodata, diagnoses, procedure, and outcome over an effective period of 36 months of laparoscopy intervention of the 54 months between September 2009 and February 2014 was done. Consent, which also included the possibility of conversion to open was obtained from the parents of the patients. Results: A total of 73 patients aged 2 weeks to 16 years with a male: female ratio of 3 to 1 had laparoscopy done during the period. Fifty-two (71.2% procedures were therapeutic, and 21 (28.8% cases were done as emergency. Laparoscopic appendectomy was the most commonly performed procedure 25 (34.3%, followed by laparoscopic orchidopexy 17 (23. 3%, and diagnostic laparoscopy for disorders of sexual differentiation in 13 (17.8%. The length of stay in hospital postoperative was 1-3 days with a mean of 1.34 ΁ 0.45 days. The complications recorded included hemorrhage, in a case of infantile hypertrophic pyloric stenosis due to failed electrocautery, one port site burns injury from diathermy dissection, and two periport pain postoperation. There was no mortality recorded. Conclusion: Pediatric laparoscopic service is gaining recognition in our practice in spite of poor resources, incessant industrial actions, and apathy from support staff. The outcomes are encouraging as the patients had minimal morbidities. Skills are improved through practice and retraining and manpower, and instruments are being expanded through our collaboration and training.

In the past, ambulatory 24-h manometry has been shown useful for the evaluation of patients with non-cardiac chest pain (NCCP). With the diagnostic improvements brought by pH-impedance monitoring and high-resolution manometry (HRM), the contribution of ambulatory 24-h manometry to the diagnosis of esophageal hypertensive disorders has become uncertain. Our aim was to assess the additional diagnostic yield of ambulatory manometry to HRM and ambulatory pH-impedance monitoring in this patient population. All patients underwent 24-h ambulatory pressure-pH-impedance monitoring and HRM. Patients had retrosternal pain as a predominant symptom and no explanation after cardiologic and digestive endoscopic evaluations. Diagnostic measurements were analyzed by two independent physicians. Fifty-nine patients met the inclusion criteria; 37.3% of the patients had their symptoms explained by abnormalities on pH-impedance monitoring and 6.8% by ambulatory manometry. Functional chest pain was diagnosed in 52.5% of the patients. High-resolution manometry, using the Chicago Classification v3.0 criteria alone, did not identify any of the four patients with esophageal spasm on ambulatory manometry. However, taking into account other abnormalities, such as simultaneous (rapid) or repetitive contractions, HRM had a sensitivity of 75% and a specificity of 98.2% for the diagnosis of esophageal spasm. In the work-up of NCCP, ambulatory 24-h manometry has a low additional diagnostic yield. However, it remains the best technique to identify esophageal spasm as the cause of symptoms. This is particularly useful when an unequivocal diagnosis is needed before treatment. © 2016 John Wiley & Sons Ltd.

Endometriosis is a sex hormone-dependent and successively progressing gynecological disease, characterized by the presence of endometrial tissue outside the uterus. The etiology of endometriosis is known to be multifactorial, and its growth depends on immunological, hormonal, genetic and environmental factors. Angiogenesis plays a key role in implantation and growth of endometriotic lesions, as well as in adhesion formation. Physiologically angiogenesis is responsible for neoangiogenesis and recruitment of new capillaries from the already existing capillaries. It is well-documented that altered angiogenesis provokes improper follicular maturation, infertility recurrent miscarriages, ovarian hyperstimulation syndrome, and carcinogenesis. Factors stimulating angionesis include angiogenin, vascular endothelial growth factor (VEGF) and fibroblast growth factor (FGF). The aim of the study was to analyze angiogenic factor concentration (angiogenin, VEGF, FGF) in blood serum and peritoneal fluid in patients with diagnosed endometriosis and idiopathic infertility. A total of 39 patients were recruited for the study including 19 patients (study group) diagnosed with endometriosis during the laparoscopic procedure and 20 patients (control group) with idiopathic infertility and no morphologic changes within the pelvis revealed during the laparoscopic procedure. All patients underwent laparoscopy during the follicular phase of the menstrual cycle. Vein blood sample was obtained before the procedure and during laparoscopy the entire peritoneal fluid was aspirated for further measurement of VEGF, FGF and angiogenin concentrations. Angiogenin concentration in peritoneal fluid was statistically higher in patient with idiopathic infertility in comparison to endometriosis (pendometriosis, but no statistical significance was found. VEGF and FGF concentration in blood serum and peritoneal fluid was similar in both groups (p>0.05). There were no significant differences between serum

The initial goal in treatment for infantile cholestasis is to exclude surgical cholestasis, especially biliary atresia (BA). In this study, we retrospectively reviewed the diagnostic course of infantile cholestasis. Between 2000 and 2009, a total of 44 infants with cholestasis were referred to our department. The median age at admission was 54 days (range: 0-143 days). The medical charts of these infants were reviewed. The initial diagnostic approach was ultrasonography followed by the qualitative detection of bilirubin in stool. The 35 infants with acholic stool and/or a small or absent gallbladder on ultrasonography were subsequently examined by hepatobiliary scintigraphy (HBS). Twenty-nine infants with negative scintigraphy findings underwent intraoperative cholangiography (lOC), and BA was finally confirmed in 24 of 44. A choledochal cyst was noted in 2, Alagille syndrome in 2, cytomegalovirus infection in 2, panhypopituitarism in 2, multiple hemangiomas of the liver in 1, and cholecystolithiasis in 1. The remaining 10 infants were diagnosed as having neonatal hepatitis. The sensitivity and specificity of HBS for BA were 100% and 54.5%, respectively. HBS is a useful modality for detection of BA with a sensitivity of 100%. The indication for IOC should depend on these scan results. (author)

Full Text Available BACKGROUND Laparoscopic surgery is a modern surgical technique in which operations are performed through small incisions and with the aid of a camera. Pain is the most common complaint following any surgery, but as compared to open surgery, the severity of pain is much lower in patients undergoing surgery via laparoscopy. The pain following laparoscopic procedure can be divided into three components- parietal pain, visceral pain and shoulder pain. The use of local long-acting anaesthetics reduces postoperative parietal pain. In this study, we tested the hypothesis that local anaesthetics instilled at the end of laparoscopic procedure are able to prevent postoperative pain during the first 24 hours post-surgery. The outcome measures were pain scores, analgesic consumption and time to analgesic request. MATERIALS AND METHODS This was a prospective study conducted by the surgical department, Pondicherry Institute of Medical Sciences for a period of 13 months. The study comprised of 50 patients with an ASA I or II who underwent laparoscopic procedures between April 2016 to May 2017. Patients in this study were randomly categorised equally into two groups; in the study group (Group A patients received local anaesthetic infiltration with bupivacaine, while in the control group (Group B, patients did not receive local anaesthetic infiltration. Following history taking and physical examination, patients were subjected to routine laboratory investigations and ultrasonogram. Contrast-enhanced computerised tomography was done in patients when indicated and following which patients diagnosed with acute appendicitis or who had symptomatic cholelithiasis were taken up for laparoscopic surgery. In the study group, local anaesthetic was instilled at the end of surgery after port removal. The total volume of infiltrated solution in the study group was 10 mL divided proportionally according to the length of the skin incisions (3 mL for 10 mm incisions and 2 m

Full Text Available Aim of the study – to investigate the prevalence of earlier non-diagnosed type 2 diabetes mellitus and prediabetes using different diagnostic approaches in patients with angiographically confirmed ischemic heart disease. Materials and methods. We studied 89 patients with ischemic heart disease, mean age 62+3,6 years. All patients had angiographically confirmed atherosclerotic lesions of coronary arteries. No patient had previously diagnosed diabetes mellitus or hyperglycemia in anamnesis. All patients underwent the detailed examination to reveal hidden diabetes or prediabetes, earlier non-diagnosed: glucose tolerance, fasting plasma glucose, glycated hemoglobin were measured and standard oral glucose tolerance test was performed. Results. Based on the results of fasting plasma glucose and oral glucose tolerance test, diabetes mellitus was diagnosed in 14 (16% patients studied, elevated glycated hemoglobin suggesting the presence of earlier non-diagnosed diabetes was found in 11 (12% patients. Each of the 3 diagnostic approaches used allowed to diagnose patients with non-diagnosed earlier type 2 diabetes mellitus and there were no statistically significant differences in the prevalence of earlier non-diagnosed diabetes depending on the method of diagnostics used, p>0.05. Prediabetes was diagnosed much more frequently – in 47 (53% patients while measuring glycated hemoglobin, in 43 (48% patients based on fasting plasma glucose levels and in 28 (31% patients according to elevated plasma glucose levels 2 hours after taking glucose. Conclusions. Our data revealed high prevalence of earlier non-diagnosed type 2 diabetes mellitus and prediabetes in patients with ischemic heart disease. The measurement of fasting plasma glucose, glycated hemoglobin and oral glucose tolerance test contribute each other in diagnostics of diabetes and prediabetes in the majority of cases.

Full Text Available Introduction. The patient’s age is one of the major risk factors of death from colorectal cancer. The role of laparo- scopic radical surgeries in the treatment of colorectal cancer in elderly patients is being studied. The purpose of the study was to evaluate the experience of surgical treatment for elderly patients with colorectal cancer. material and methods. The treatment outcomes of 106 colorectal cancer patients aged 75 years or over, who underwent surgery between 2013 and 2015 were presented. Out of them, 66 patients underwent laparatomy and 40 patients underwent laparoscopy. Patients were matched for ASA and CR-PОSSUM scales, age-and body mass index, dis- ease stage and type of surgery. Results. The mean duration of surgery was significantly less for laparoscopy than for laparotomy (127 min versus 146 min. Intraoperative blood loss was higher in patients treated by laparotomy than by laparoscopy (167 ml versus 109 ml, but the differences were insignificant (р=0.36. No differences in lymphodissection quality and adequate resection volume between the groups were found. The average hospital stay was not significantly shorter in the laparoscopic group (р=0.43. Complications occurred with equal frequency in both groups (13.6 % compared to 15.0 %. The median follow-up time was 16 months (range, 6-30 months. The number of patients died during a long-term follow-up was 2 times higher after laparotomic surgery than after laparoscopic surgery, however, the difference was not statistically significant. Conclusion. Postoperative compli- cations in elderly patients with colorectal cancer did not exceed the average rates and did not depend on the age. Both groups were matched for the intraoperative bleeding volume and quality of lymphodenectomy. Significantly shorter duration of laparoscopic surgery was explained by the faster surgical access however, it showed no benefit in reducing the average length of hospital stay and decreasing the number of

Dipyridamole stress perfusion cardiovascular magnetic resonance (CMR) is used to detect coronary artery disease (CAD). However, few data are available on the diagnostic value of the systolic dysfunction induced by dipyridamole. This study investigated whether the induction of systolic dysfunction supplements the diagnostic information provided by perfusion imaging in the detection of CAD. Overall, 166 patients underwent dipyridamole CMR and quantitative coronary angiography, with CAD being defined as a stenosis > or =70%. Systolic dysfunction at rest, systolic dysfunction with dipyridamole, induced systolic dysfunction, and stress first-pass perfussion deficit (PD) and delayed enhancement were quantified. In the multivariate analysis, PD (hazard ratio [HR]=1.6; 95% confidence interval [CI], 1.33-1.91;Pstatistic for predicting CAD (0.81 vs. 0.87; P=.02). Combining induced systolic dysfunction with perfusion imaging increases the diagnostic accuracy of detecting CAD and enables patients with severe ischemia and a high probability of CAD to be identified.

Allergy to cats and dogs and polysensitization towards these animals are associated with severe childhood asthma. Molecular-based allergy diagnostics offers new opportunities for improved characterization and has been suggested to be particularly useful in patients with polysensitization and/or severe asthma. The aim was to use extract- and molecular-based allergy diagnostics to compare patterns of IgE sensitization towards aeroallergens in children with problematic severe and controlled asthma. Children with a positive ImmunoCAP towards any furry animal (cat, dog or horse) were recruited from a Nationwide Swedish study on severe childhood asthma. Severe (n = 37, age 13 years) and controlled (n = 28, age 14 years) asthmatics underwent assessment of allergic sensitization by ImmunoCap (kUA /l) and immunosolid-phase allergen chip (ISAC). In addition, Asthma Control Test, spirometry and a methacholine challenge were performed. Children with severe asthma had lower asthma control (p Molecular-based allergy diagnostics revealed a more complex molecular spreading of allergen components in children with the most severe disease. © 2014 John Wiley & Sons A/S.

We clinically investigated 34 patients with obstructive colorectal cancer who underwent placement of a colonic stent as a bridge to surgery(BTS), focusing on endoscopic findings after stent placement.Twenty -nine patients(85.3%)underwent colonoscopy after stent placement, and the entire large intestine could be observed in 28(96.6%).Coexisting lesions were observed in 22(78.6%)of these 28 patients.The lesions comprised adenomatous polyps in 17 patients(60.7%), synchronous colon cancers in 5 patients(17.9%), and obstructive colitis in 3 patients(10.7%), with some overlapping cases.All patients with multiple cancers underwent one-stage surgery, and all lesions were excised at the same time.Colonoscopy after colonic stent placement is important for preoperative diagnosis of coexisting lesions and planning the extent of resection. These considerations support the utility of colonic stenting for BTS.

A 23-year-old woman with MELAS (mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes) underwent a laparoscopy-assisted appendectomy. MELAS syndrome is a multisystemic disease caused by mitochondrial dysfunction. General anesthesia has several potential hazards to patients with MELAS syndrome, such as malignant hyperthermia, hypothermia, and metabolic acidosis. In this case, anesthesia was performed with propofol, remifentanil TCI, and atracurium without any surgical or anesthetic complications. We discuss the anesthetic effects of MELAS syndrome.

Laparoscopic Resection of a Torsed Big Myoma at 16th Weeks of Gestation

Full Text Available Myomas are the most common benign tumors of the uterus; however, only 1% to 4% of women were diagnosed with myoma during pregnancy. Although a majority of myomas do not cause any problems during pregnancy and rarely present with torsion or necrosis, myomas might lead to an acute abdomen, which then indicate need for an urgent myomectomy. There are various causes for an acute abdomen during pregnancy, and it is not always easy to make the definitive diagnosis with non-invasive diagnostic tools such as ultrasonography. Because the uterus displaces the intra-abdominal organs during pregnancy, diagnosis of a surgical emergency may be delayed and, consequently, increase maternal morbidity and mortality. If a surgical emergency is indicated, laparoscopy is a safe alternative to laparotomy during pregnancy, requiring a shorter hospital stay and less analgesic; therefore, all surgeons and gynecologists should be able to perform a laparoscopy when needed in each trimester of pregnancy. Herein, we report a 31-year-old primigravid woman presented with an acute abdomen at 16 weeks gestation. Ultrasound examination revealed a nearly 10 cm myoma at the right side of the uterine fundus. Suspecting a torsed myoma, an urgent diagnostic laparoscopy, which revealed a large, torsed, subserous myoma with a 2cm base, was performed. Laparoscopic resection and morcellation was done successfully. No intra-operative or post-operative complications were encountered, and the woman gave birth to a healthy infant at term. By presenting this case, we suggest the safe use of laparoscopic myomectomy of a relatively big myoma even in the second trimester of pregnancy.

The exposure of population to ionizing radiations in medical diagnostic purposes represents a planed exposure procedure, medically justified, having a direct impact on patient health state. A justification of exposure, with a result that can confirm a clinical diagnostic, implies further important steps in treatment decisions. Optimization in patients radiological protection is the result of observing the reference levels recommendations, which maintains a reasonable individual exposure to ionizing radiation in medical purpose. In this paper we investigated the justification of 4189 exposures of patients who underwent planed diagnostic medical investigation over 36 months in a radiological unit. The most frequent investigation concerned the spinal column in 38.3% of total exposures-mainly at lumbar level (63.0% and 24.1%, respectively of total number of exposures), followed by limb bones (20.6%) and thorax (26.9%). Justification of practices included: rheumatic pains in 45.8% of exposures followed by traumatic injuries (20.6%), pleural and pulmonary pathology (19.3%), malignant processes (12.3%), ear-nose-throat investigations (1.1%) and car accidents (0.9%). The females over 40 years old were the group with the highest number of medical exposures, with 54.5% of total practices. This study revealed that the number of medical exposures justification is almost equal with non-justified examinations, confirming a not so good correlation between clinical diagnostic and the required radiological investigation. The percentages of justified versus non-justified practices indicated by specialist physicians and general practitioners were slightly equal - 59.3% vs. 40.7%, 56.9% vs. 43.1%, respectively. The analysis of data concluded that either specialist/general physicians must evaluate more rigorously the patients and all clinical signs in order to reduce as reasonable as possible the non-justified medical exposures to ionizing radiations, and thus to avoid financial and

To compare levels of interleukin-6 (IL-6), intracellular adhesion molecule-1 (ICAM-1), and glycodelin A in serum and peritoneal fluid of patients with and without endometriosis, and to correlate levels with disease stage. An observational study was undertaken at Mansoura University Hospital, Egypt, between March 2014 and June 2015. Patients aged 21-48 years laparoscopically diagnosed with endometriosis and those without endometriosis who underwent laparoscopy for tubal ligation were included. Levels of IL-6, ICAM-1, and glycodelin A were measured in samples of serum and peritoneal fluid. Receiver operating characteristic curves were used to evaluate diagnostic accuracy. Forty-eight women with endometriosis and 20 without the disorder were included. IL-6 and glycodelin A levels in serum and peritoneal fluid were higher in the endometriosis group than in the control group (Pperitoneal fluid markers were 85.4% and 89.0%, 60.4% and 50.0%, and 89.6% and 90.0%, respectively. IL-6 and glycodelin A levels in serum and peritoneal fluid increased with disease stage (Pendometriosis and are positively correlated with the disease stage.

Ashish Lal Shrestha

2016-01-01

Full Text Available Background. Inflammatory Fibroid Polyp (IFP of the colon is an exceedingly rare condition. Since 1952 till now only 32 cases have been reported worldwide of which only 5 were giant (>4 cm polyps mostly found in the caecum (15 cases with only 3 in the descending colon. Case Presentation. A 36-year-old female with no previous illness presented to the emergency unit with an acute onset pain over the right hypochondrium for 3 days associated with intermittent fever and anorexia. As she had evidence of localized peritonitis she underwent a diagnostic laparoscopy and subsequently an exploratory laparotomy. A mass measuring 8 × 7 × 5 cm arising from the hepatic flexure of colon was noted. Right hemicolectomy with ileotransverse anastomosis was performed. The mass was subsequently reported to be IFP. Conclusion. IFP is a very rare condition with clinical presentation depending upon its size and location. Definitive diagnosis is possible with histopathological examination of tissue aided by immunohistochemical studies. Surgical resection has been the most common method of treatment especially for large and giant colonic IFPs owing to challenges in terms of diagnosis and technical difficulties associated with endoscopic methods.

Full Text Available Abstract Background Adenocarcinoma of the vermiform appendix is a rare neoplasm of the gastrointestinal tract. Presentation mimics acute appendicitis, but right iliac fossa mass and intestinal obstruction have also been reported. These presentations reflect various stages of a locally expanding tumour causing luminal obstruction of appendix. The investigation and subsequent management with a review of the literature is presented. Case presentation We report a case of appendicular adenocarcinoma found unexpectedly in a 43 year old male who presented with urinary symptoms. Cystoscopy and uretero-renoscopy showed normal bladder but external compression of the ureters and therefore bilateral stents were inserted. CT scan showed a caecal mass. After colonoscopy, that showed external compression, and diagnostic laparoscopy the patient underwent right hemicolectomy. Histopathology revealed well differentiated adenocarcinoma with signet ring morphology with multiple lymph node involvement. The patient was referred for chemotherapy where he received infusional 5 fluorouracil but died 7 months after surgery. Conclusion Patients with atypical manifestations related to right lower abdominal quadrant should be thoroughly investigated with an open mind. Every attempt should be made to make a precise diagnosis through all the available means to direct the treatment along correct lines.

Full Text Available The aim was to describe the outcome of neonatal hearing screening (NHS and audiological diagnosis in neonates in the NICU. The sample was divided into Group I: neonates who underwent NHS in one step and Group II: neonates who underwent a test and retest NHS. NHS procedure was automated auditory brainstem response. NHS was performed in 82.1% of surviving neonates. For GI, referral rate was 18.6% and false-positive was 62.2% (normal hearing in the diagnostic stage. In GII, with retest, referral rate dropped to 4.1% and false-positive to 12.5%. Sensorineural hearing loss was found in 13.2% of infants and conductive in 26.4% of cases. There was one case of auditory neuropathy spectrum (1.9%. Dropout rate in whole process was 21.7% for GI and 24.03% for GII. We concluded that it was not possible to perform universal NHS in the studied sample or, in many cases, to apply it within the first month of life. Retest reduced failure and false-positive rate and did not increase evasion, indicating that it is a recommendable step in NHS programs in the NICU. The incidence of hearing loss was 2.9%, considering sensorineural hearing loss (0.91%, conductive (1.83% and auditory neuropathy spectrum (0.19%.

We herein report a case of lung metastases with unusual radiological appearances that mimicked those of chronic airway infection, causing diagnostic difficulty. A 60-year-old woman who underwent liver transplantation from a living donor was incidentally diagnosed with bile duct adenocarcinoma after a histopathological analysis of her explanted liver. Six months later, chest computed tomography (CT) revealed bilateral bronchogenic dissemination that had gradually worsened, suggesting chronic airway infection. A biopsy with bronchoscopy from a mass lesion beyond a segmental bronchus revealed adenocarcinoma identical to that of her bile duct adenocarcinoma, leading to the diagnosis of multiple lung metastases from bile duct adenocarcinoma.

Full Text Available The present study is undertaken to establish the usefulness of laparoscopic cholecystectomy and to know its merits and demerits as compared to open cholecystectomy in children. In all, 28 patients who underwent cholecystectomy (8 open and 20 laparoscopic cholecystectomy in B.Y.L. Nair hospital between July 1999 and March 2004 were analyzed. Calculous cholecystitis was found to be the most common indication for surgery. Operative time for laparoscopic cholecystectomy was more than that in open cholecystectomy in the early phase of laparoscopy, which got reduced as we gained experience. The requirement of parenteral antibiotics and analgesics and the duration of stay were significantly shorter with laparoscopy. The advantages for a child in laparoscopic cholecystectomy as compared to open cholecystectomy are minimal pain, avoidance of an upper abdominal incision, cosmesis and shorter duration of hospitalization with quick return to home and school. Thus, laparoscopic cholecystectomy is safe and efficacious in children.

Background & objectives: A knowledge-based, logically-linked online telepsychiatric decision support system for diagnosis and treatment of mental disorders was developed and validated. We evaluated diagnostic accuracy and reliability of the application at remote sites when used by non-psychiatrists who underwent a brief training in its use through video-conferencing. Methods: The study was conducted at a nodal telepsychiatry centre, and three geographically remote peripheral centres. The diagnostic tool of application had a screening followed by detailed criteria-wise diagnostic modules for 18 psychiatric disorders. A total of 100 consecutive consenting adult outpatients attending remote telepsychiatry centres were included. To assess inter-rater reliability, patients were interviewed face to face by non-specialists at remote sites using the application (active interviewer) and simultaneously on online application via video-conferencing by a passive assessor at nodal centre. Another interviewer at the nodal centre rated the patient using Mini-International Neuropsychiatric Interview (MINI) for diagnostic validation. Results: Screening sub-module had high sensitivity (80-100%), low positive predictive values (PPV) (0.10-0.71) but high negative predictive value (NPV) (0.97-1) for most disorders. For the diagnostic sub-modules, Cohen's kappa was >0.4 for all disorders, with kappa of 0.7-1.0 for most disorders. PPV and NPV were high for most disorders. Inter-rater agreement analysis revealed kappa >0.6 for all disorders. Interpretation & conclusions: Diagnostic tool showed acceptable to good validity and reliability when used by non-specialists at remote sites. Our findings show that diagnostic tool of the telepsychiatry application has potential to empower non-psychiatrist doctors and paramedics to diagnose psychiatric disorders accurately and reliably in remote sites.

To examine the relation between lifestyle and the number of metabolic syndrome (MetS) diagnostic components in a general population, and to find a means of preventing the development of MetS components. We examined baseline data from 3,365 participants (2,714 men and 651 women) aged 19 to 69 years who underwent a physical examination, lifestyle survey, and blood chemical examination. The physical activity of each participant was classified according to the International Physical Activity Questionnaire (IPAQ). We defined four components for MetS in this study as follows: 1) high BP: systolic BP > or = 130 mmHg or diastolic BP > or = 85 mmHg, or the use of antihypertensive drugs; 2) dyslipidemia: high-density lipoprotein-cholesterol concentration or = 150 mg/dL, or on medication for dyslipidemia; 3) Impaired glucose tolerance: fasting blood sugar level > or = 110 mg/d, or if less than 8 hours after meals > or = 140 mg/dL), or on medication for diabetes mellitus; 4) obesity: body mass index > or = 25 kg/m(2). Those who had 0 to 4 MetS diagnostic components accounted for 1,726, 949, 484, 190, and 16 participants, respectively, in the Poisson distribution. Poisson regression analysis revealed that independent factors contributing to the number of MetS diagnostic components were being male (regression coefficient b=0.600, p physical activity was inversely associated with the number of MetS diagnostic components, whereas smoking was not associated.

The present study was undertaken to evaluate the diagnostic utility of fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (F-18 FDG PET/CT) in patients presenting as pyrexia of unknown origin (PUO). Forty-seven patients (31 males and 16 females; mean age of 42.7 ± 19.96 years) presenting as PUO to the Department of Medicine at the All India Institute of Medical Sciences, New Delhi over a period of 2 years underwent F-18 FDG PET/CT. PET ⁄ CT was considered supportive when its results correlated with the final definitive diagnosis. Final diagnosis was made on the basis of combined evaluation of history, clinical findings, investigations, and response to treatment. Thirty-five PET/CT studies (74.5%) were positive. However, only 18 (38.3%) were supportive of the final diagnosis. In three patients (6.4%), PET/CT was considered diagnostic as none of the other investigations including contrast-enhanced computed tomography of chest and abdomen, and directed tissue sampling could lead to the final diagnosis. All these three patients were diagnosed as aortoarteritis. Fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography is an important emerging modality in the workup of PUO. It supported the final diagnosis in 38% of our patients and was diagnostic in 6.4% of patients. Thus, PET/CT should only be considered as second-line investigation for the diagnostic evaluation of PUO; especially in suspected noninfectious inflammatory disorders

To compare the performance of microdose flare-up (MF) and flexible-multidose gonadotropin-releasing hormone (GnRH) antagonist protocols in poor responder patients who underwent intracytoplasmic sperm injection (ICSI). One hundred and 12 consecutive patients (217 cycles) suspected to have poor ovarian response were enrolled. Group 1 (MF GnRH agonist group) constituted 64 patients (135 cycles) who underwent MF GnRH agonist protocol. Group 2 (flexible-multidose GnRH antagonist group) constituted 48 patients (82 cycles) who underwent flexible-multidose GnRH antagonist protocol. The duration of stimulation (d) (11.5 +/- 2.1 vs. 10.4 +/- 2.7, p or = seven blastomeres and < 10% fragmentation at day 3 (35.9% vs. 65.1%, p < 0.05) were significantly lower in Group 1 when compared to Group 2. The number of embryos transferred (2.2 +/- 1.3 vs. 2.4 +/- 0.9), the clinical pregnancy per embryo transfer (16.3% vs. 25.8%), and the implantation rate (8.6% vs. 12.2%) were comparable between groups. Although the flexible-multidose GnRH antagonist protocol produced better oocyte and embryo parameters, the clinical pregnancy rate and the implantation rates were comparable between the flexible-multidose GnRH antagonist and MF protocols in poor responder patients.

To investigate the diagnostic value of CT colonography for the detection of colorectal polyps. From December 2004 to December 2005, 399 patients underwent CT colonography and follow-up conventional colonoscopy. We excluded cases of advanced colorectal cancer. We retrospectively analyzed the CT colonography findings and follow-up conventional colonoscopy findings of 113 patients who had polyps more than 6 mm in diameter. Radiologists using 3D and 2D computer generated displays interpreted the CT colonography images. The colonoscopists were aware of the CT colonography findings before the procedure. CT colonography detected 132 polyps in 107 of the 113 patients and conventional colonoscopy detected 114 colorectal polyps more than 6 mm in diameter in 87 of the 113 patients. The sensitivity of CT colonography analyzed per polyp was 91% (41/45) for polyps more than 10 mm in diameter and 89% (101/114) for polyps more than 6 mm in diameter. Thirteen polyps were missed by CT colonography and were detected on follow-up conventional colonoscopy. CT colonography is a sensitive diagnostic tool for the detection of colorectal polyps and adequate bowel preparation, optimal bowel distention and clinical experience are needed to reduce the rate of missing appropriate lesions

To study the utility of ultrasound and computed tomography (CT) in case of suspected appendicitis. To determine the diagnostic yield in terms of different clinical contexts and patient characteristics. to assess the costs and benefits of introducing these techniques and propose a protocol for their use. Negative appendectomies, complications and length of hospital stay in a group of 152 patients with suspected appendicitis who underwent ultrasound and CT were compared with those of 180 patients who underwent appendectomy during the same time period, but had not been selected for the first group: these patients costs for each group were calculated. In the first group, the diagnostic value of the clinical signs was also evaluated. The reliability of the clinical signs was limited, while the results with ultrasound and CT were excellent. The incidence of negative appendectomy was 9.6% in the study group and 12.2% in the control group. Moreover, there were fewer complications and a shorter hospital stay in the first group. Among men, however, the rate of negative appendectomy was lower in the control group. The cost of using ultrasound and CT in the management of appendicitis was only slightly higher than that of the control group. Although ultrasound and CT are not necessary in cases in which the probability of appendicitis is low or in men presenting clear clinical evidence, the use of these techniques is indicated in the remaining cases in which appendicitis is suspected. In children, ultrasound is the technique of choice. In all other patients, if negative results are obtained with one of the two techniques, the other should be performed. (Author) 49 refs.

Transverse Skin Crease versus Vertical Midline Incision versus Laparoscopy for Right Hemicolectomy: A Systematic Review—Current Status of Right Hemicolectomy

Full Text Available Purpose. The right hemicolectomy may be conducted through laparoscopic or laparotomic surgery, transverse or midline incisions. The transverse laparotomy offers some advantages compared to the midline laparotomy and laparoscopy. A literature review was performed to evaluate the possible advantages of the transverse incision versus midline incision or laparoscopic right hemicolectomy. Methods. A systematic research was performed in Medline, Embase, Cochrane Central Register of Controlled Trials, CINAHL, BioMed Central, and the Science Citation Index. Results. Laparotomic right hemicolectomy with transverse incision is preferable to laparotomic hemicolectomy with midline incision. A transverse incision offers a lessened postoperative pain following physical activity, a lessened need to administer analgesic therapy during the post-operative time, better aesthetic results, and a better post-operative pulmonary function. Open surgery with transverse or midline incision ensured a shorter operative time, lower costs and a greater length of the incision compared to the laparoscopic. However, there are no differences in the oncological outcomes. Conclusions. It was not possible to identify significant differences between the open right hemicolectomy with transverse incision versus the open right hemicolectomy with midline incision or laparoscopic hemicolectomy.

The purpose of this study was to retrospectively evaluate the diagnostic accuracy and complications of CT-guided core needle biopsy (CT-guided CNB) of pleural lesion and the possible effects of influencing factors. From September 2007 to June 2013, 88 consecutive patients (60 men and 28 women; mean [+/- standard deviation] age, 51.1 +/- 14.4 years; range, 19-78 years) underwent CT-guided CNB, which was performed by two experienced chest radiologists in our medical center. Out of 88 cases, 56 (63%) were diagnosed as malignant, 28 (31%) as benign and 4 (5%) as indeterminate for CNB of pleural lesions. The final diagnosis was confirmed by either histopathological diagnosis or clinical follow-up. The diagnostic accuracy, sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and complication rates were statistically evaluated. Influencing factors (patient age, sex, lesion size, pleural-puncture angle, patient position, pleural effusion, and number of pleural punctures) were assessed for their effect on accuracy of CT-guided CNB using univariate and subsequent multivariate analysis. Diagnostic accuracy, sensitivity, specificity, PPV, and NPV were 89.2%, 86.1%, 100%, 100%, and 67.8%, respectively. The influencing factors had no significant effect in altering diagnostic accuracy. As far as complications were concerned, occurrence of pneumothorax was observed in 14 (16%) out of 88 patients. Multivariate analysis revealed lesion size/pleural thickening as a significant risk factor (odds ratio [OR]: 8.744, p = 0.005) for occurrence of pneumothorax. Moreover, presence of pleural effusion was noted as a significant protective factor (OR: 0.171, p = 0.037) for pneumothorax. CT-guided CNB of pleural lesion is a safe procedure with high diagnostic yield and low risk of significant complications.

For the diagnostics of nerve lesions an imaging method is necessary to visualize peripheral nerves and their surrounding structures for an etiological classification. Clinical neurological and electrophysiological investigations provide functional information about nerve lesions. The information provided by a standard magnetic resonance imaging (MRI) examination is inadequate for peripheral nerve diagnostics; however, MRI neurography is suitable but on the other hand a resource and time-consuming method. Using ultrasonography for peripheral nerve diagnostics. With ultrasonography reliable diagnostics of entrapment neuropathies and traumatic nerve lesions are possible. The use of ultrasonography for neuropathies shows that a differentiation between different forms is possible. Nerve ultrasonography is an established diagnostic tool. In addition to the clinical examination and clinical electrophysiology, structural information can be obtained, which results in a clear improvement in the diagnostics. Ultrasonography has become an integral part of the diagnostic work-up of peripheral nerve lesions in neurophysiological departments. Nerve ultrasonography is recommended for the diagnostic work-up of peripheral nerve lesions in addition to clinical and electrophysiological investigations. It should be used in the clinical work-up of entrapment neuropathies, traumatic nerve lesions and spacy-occupying lesions of nerves. (orig.) [de

Tune-Based Halo Diagnostics

2003-01-01

Tune-based halo diagnostics can be divided into two categories -- diagnostics for halo prevention, and diagnostics for halo measurement. Diagnostics for halo prevention are standard fare in accumulators, synchrotrons, and storage rings, and again can be divided into two categories -- diagnostics to measure the tune distribution (primarily to avoid resonances), and diagnostics to identify instabilities (which will not be discussed here). These diagnostic systems include kicked (coherent) tune measurement, phase-locked loop (PLL) tune measurement, Schottky tune measurement, beam transfer function (BTF) measurements, and measurement of transverse quadrupole mode envelope oscillations. We refer briefly to tune diagnostics used at RHIC and intended for the SNS, and then present experimental results. Tune-based diagnostics for halo measurement (as opposed to prevention) are considerably more difficult. We present one brief example of tune-based halo measurement

Aim: to determine the effectiveness of a new imaging algorithm in the investigation of suspected pulmonary embolism (PE). Materials and methods: A new imaging algorithm for suspected PE was introduced following the installation of a multisection computed tomography (CT) machine at our institution. Before its installation, patients with suspected PE were evaluated with ventilation/perfusion (V/Q) scintigraphy. Subsequently, patients were triaged according to chest radiography (CR) and respiratory history to either lung scintigraphy or CT pulmonary angiography (CTPA). Patients with a normal CR and no history of lung disease were evaluated using perfusion (Q) scintigraphy [ventilation (V) scintigraphy was no longer performed]. Patients with an abnormal CR, asthma or chronic lung disease were evaluated using CTPA. All V/Q images in a continuous 3-year period before the introduction of the new imaging algorithm and all Q images performed in a 3-year period after its introduction were retrospectively reviewed. Imaging reports were categorized into normal, non-diagnostic (low or intermediate probability) or high probability for PE. Patients in the later group who subsequently underwent CTPA, were also reviewed. Results: After the policy change the percentage of normal scintigrams significantly increased (39 to 60%; p < 0.001). There was a non-significant increase in the percentage of high probability scintigrams (15 to 18%; p = 0.716). Overall the diagnostic yield of lung scintigraphy improved significantly (54 to 78%; p < 0.001). Conclusion: the diagnostic performance of lung scintigraphy can be improved by careful triage of patients to either Q scintigraphy or CTPA based on clinical history and CR findings. Q scintigraphy remains a valuable diagnostic test in the investigation of suspected PE in carefully selected patients

Peripheral arterial disease (PAD) represents a major and highly prevalent complication in patients with diabetes mellitus. The diagnostic, non-invasive work-up by computed tomography angiography (CTA) is limited in the presence of extensive calcification. The aim of the study was to determine the diagnostic accuracy of dual energy CTA (DE-CTA) for the detection and characterization of PAD in patients with diabetes mellitus. In this study 30 diabetic patients with suspected or known PAD were retrospectively included in the analysis. All subjects underwent DE-CTA (Somatom Definition Flash, Siemens Healthcare, Erlangen, Germany) prior to invasive angiography, which served as the reference standard. Blinded analysis included assessment of the presence and degree of peripheral stenosis on curved multiplanar reformatting (MPR) and maximum intensity projections (MIP). Conventional measures of diagnostic accuracy were derived. Among the 30 subjects included in the analysis (83 % male, mean age 70.0 ± 10.5 years, 83 % diabetes type 2), the prevalence of critical stenosis in 331 evaluated vessel segments was high (30 %). Dual energy CT identified critical stenoses with a high sensitivity and good specificity using curved MPR (100 % and 93.1 %, respectively) and MIP images (99 % and 91.8 %, respectively). In stratified analysis, the diagnostic accuracy was higher for stenosis pertaining to the pelvic and thigh vessels as compared with the lower extremities (curved MPR accuracy 97.1 % vs. 99.2 vs. 90.9 %; respectively, p < 0.001). The use of DE-CTA allows reliable detection and characterization of peripheral arterial stenosis in patients with diabetes mellitus with higher accuracy in vessels in the pelvic and thigh regions compared with the vessels in the lower legs.

Adrenocorticotropic hormone (ACTH) stimulation is recommended in adrenal vein sampling (AVS) for primary aldosteronism (PA) to improve the AVS success rate. However, this method can confound the subtype diagnosis. Gene mutations or pathological characteristics may be related to lateralization by AVS. This study aimed to compare the rate of diagnostic discrepancy by AVS pre- versus post-ACTH stimulation and to investigate the relationship between this discrepancy and findings from immunohistochemical and genetic analyses of PA. We evaluated 195 cases of AVS performed in 2011–2017. All surgical specimens were analyzed genetically and immunohistochemically. Based on the criteria, AVS was successful in 158 patients both pre- and post-ACTH; of these patients, 75 showed diagnostic discrepancies between pre- and post-ACTH. Thus, 19 patients underwent unilateral adrenalectomy, of whom 16 had an aldosterone-producing adenoma (APA) that was positive for CYP11B2 immunostaining. Of them, 10 patients had discordant lateralization between pre- and post-ACTH. In the genetic analysis, the rate of somatic mutations was not significantly different between APA patients with versus without a diagnostic discrepancy. In the immunohistochemical analysis, CYP11B2 levels and the frequency of aldosterone-producing cell clusters (APCCs) in APAs were almost identical between patients with versus without a diagnostic discrepancy. However, both the number and summed area of APCCs in APAs were significantly smaller in patients with concordant results than in those whose diagnosis changed to bilateral PA post-ACTH stimulation. In conclusion, lateralization by AVS was affected by APCCs in the adjacent gland, but not by APA-related factors such as somatic gene mutations. PMID:29899838

Ventral incisional hernia (VIH) is not uncommon following liver transplantation. Open repair was traditionally adopted for its management. Laparoscopic repair of VIH has been performed successfully in nontransplant patients with evidence of reduced recurrence rates and hospital stay. However, the application of VIH in post-transplantation patients has not been well established. Herein, we provide our initial experience with laparoscopic repair of post-transplantation VIH. From March 2015 to March 2016, 18 cases of post-transplantation VIH were subjected to laparoscopic repair (laparoscopy group). A historical control group of 17 patients who underwent conventional open repair (open group) from January 2013 to January 2015 were identified for comparison. The demographics and clinical outcomes were retrospectively compared. There were no significant differences among basic demographics between the 2 groups. No conversion was recorded in the laparoscopy group. Recurrence of VIH up to the end of the study period was not noted. In the laparoscopy group, the minor complications were lower (16.7% vs 52.9%; P = .035), the length of hospital stay was shorter (3 d vs 7 d, P = .007), but the median operative time was longer (137.5 min vs 106 min; P = .003). Laparoscopic repair of post-transplantation VIH is a safe and feasible procedure with shorter length of hospital stay. Copyright © 2017 Elsevier Inc. All rights reserved.

In the acquisition of new skills that are difficult to master, such as those required for laparoscopy, feedback is a crucial component of the learning experience. Optimally, feedback should accurately reflect the task performance to be improved and be proximal to the training experience. In surgery, however, feedback typically is in vivo. The development of virtual reality training systems currently offers new training options. This study investigated the effect of feedback type and quality on laparoscopic skills acquisition. For this study, 32 laparoscopic novices were prospectively randomized into four training conditions, with 8 in each group. Group 1 (control) had no feedback. Group 2 (buzzer) had audio feedback when the edges were touched. Group 3 (voiced error) had an examiner voicing the word "error" each time the walls were touched. Group 4 (both) received both the audio buzzer and "error" voiced by the examiner All the subjects performed a maze-tracking task with a laparoscopic stylus inserted through a 5-mm port to simulate the fulcrum effect in minimally invasive surgery (MIS). A computer connected to the stylus scored an error each time the edge of the maze was touched, and the subjects were made aware of the error in the aforementioned manner. Ten 2-min trials were performed by the subjects while viewing a monitor. At the conclusion of training, all the subjects completed a 2-min trial of a simple laparoscopic cutting task, with the number of correct and incorrect incisions recorded. Group 4 (both) made significantly more correct incisions than the other three groups (F = 12.13; df = 3, 28; p < 0.001), and also made significantly fewer errors or incorrect incisions (F = 14.4; p < 0.0001). Group 4 also made three times more correct incisions and 7.4 times fewer incorrect incisions than group 1 (control). The type and quality of feedback during psychomotor skill acquisition for MIS have a large effect on the strength of skills generalization to a simple

The development of molecular diagnostics is a complex endeavor, with multiple regulatory pathways to consider and numerous approaches to development and commercialization. Companion diagnostics, devices which are "essential for the safe and effective use of a corresponding drug or diagnostic product" (see U.S. Food & Drug Administration, In Vitro Diagnostics - Companion Diagnostics, U.S. Dept. of Health & Human Services(2016), available at https://www.fda.gov/medicaldevices/productsandmedicalprocedures/invitrodiagnostics/ucm407297.htm ) and complementary diagnostics, which are more broadly associated with a class of drug, are becoming increasingly important as integral components of the implementation of precision medicine. Areas covered: The following article will highlight the intellectual property ('IP') considerations pertinent to molecular diagnostics development with special emphasis on companion diagnostics. Expert opinion/commentary Summary: For all molecular diagnostics, intellectual property (IP) concerns are of paramount concern, whether the device will be marketed only in the United States or abroad. Taking steps to protect IP at each stage of product development is critical to optimize profitability of a diagnostic product. Also the legal framework around IP protection of diagnostic technologies has been changing over the previous few years and can be expected to continue to change in the foreseeable near future, thus, a comprehensive IP strategy should take into account the fact that changes in the law can be expected.

Nonoperative management for patients with rectal cancer who have achieved a clinical complete response after chemoradiotherapy is becoming increasingly important in recent years. However, the definition of and modality used for patients with clinical complete response differ greatly between institutions, and the role of endoscopic assessment as a nonoperative approach has not been fully investigated. This study aimed to investigate the ability of endoscopic assessments to predict pathological regression of rectal cancer after chemoradiotherapy and the applicability of these assessments for the watchful waiting approach. This was a retrospective comparative study. This study was conducted at a single referral hospital. A total of 198 patients with rectal cancer underwent preoperative endoscopic assessments after chemoradiotherapy. Of them, 186 patients underwent radical surgery with lymph node dissection. The histopathological findings of resected tissues were compared with the preoperative endoscopic findings. Twelve patients refused radical surgery and chose watchful waiting; their outcomes were compared with the outcomes of patients who underwent radical surgery. The endoscopic criteria correlated well with tumor regression grading. The sensitivity and specificity for a pathological complete response were 65.0% to 87.1% and 39.1% to 78.3%. However, endoscopic assessment could not fully discriminate pathological complete responses, and the outcomes of patients who underwent watchful waiting were considerably poorer than the patients who underwent radical surgery. Eventually, 41.7% of the patients who underwent watchful waiting experienced uncontrollable local failure, and many of these occurrences were observed more than 3 years after chemoradiotherapy. The number of the patients treated with the watchful waiting strategy was limited, and the selection was not randomized. Although endoscopic assessment after chemoradiotherapy correlated with pathological response

The 3 phase 3 CHAMPION (Cangrelor vs Standard Therapy to Achieve Optimal Management of Platelet Inhibition) trials collectively demonstrated the safety of transitioning from cangrelor, a potent, parenteral rapidly-acting P2Y 12 inhibitor, to clopidogrel in patients who underwent percutaneous coronary intervention (PCI). However, variation in timing of therapy, site-specific binding, and drug half-lives may theoretically complicate switching to other oral P2Y 12 inhibitors. Since regulatory approval, limited data are available regarding the "real-world" safety and tolerability of transitioning to these more potent oral P2Y 12 antagonists. From November 2015 to January 2017, we evaluated the clinical profiles and efficacy and safety outcomes in cangrelor-treated patients who underwent PCI transitioned to clopidogrel (n = 42) or ticagrelor (n = 82) at a large, tertiary care center. Most patients receiving cangrelor underwent PCI with a drug-eluting stent for acute coronary syndrome via a radial approach in the background of unfractionated heparin. Stent thrombosis within 48 hours was rare and occurred in 1 patient treated with ticagrelor. Global Use of Strategies to Open Occluded Coronary Arteries-defined bleeding occurred in 20% of patients switched to ticagrelor and 29% of patients switched to clopidogrel, but none were severe or life-threatening. In conclusion, rates of stent thrombosis and severe/life-threatening bleeding were low and comparable with those identified in the CHAMPION program, despite use of more potent oral P2Y 12 inhibition.

To evaluate the feasibility and diagnostic accuracy of the balloon dilatation biopsy for the biliary stricture through the percutaneous transhepatic biliary drainage (PTBD) tract. The study included 35 patients who underwent balloon dilatation biopsy for the biliary stricture through the PTBD tract. Balloon dilatation was done with a balloon catheter of 10-mm or 12-mm diameter. Soft tissue adherent to the retrieved balloon catheter and soft tissue components separated by gauze filtration of evacuated bile were sampled for histopathologic examination. The results were compared with the final diagnosis which was made by clinical and imaging follow-up for mean 989 days (n = 34) and surgery with histopathologic examination (n = 1). Procedure-related complications and diagnostic accuracy were assessed. Tissues suitable for histopathologic examination were obtained in 31 out of 35 patients (88.6%). In 3 patients, self-limiting hemobilia was noted. No major complication was noted. The sensitivity, specificity, diagnostic accuracy, positive and negative predictive values for diagnosis of malignant stricture were 70.0%, 100%, 90.3%, 100%, and 87.5%, respectively. Balloon dilatation biopsy of the biliary stricture through the PTBD tract is a feasible and accurate diagnostic method. It can be a safe alternative to the endoscopic retrograde cholangiography biopsy or forceps biopsy through the PTBD tract.

To evaluate the diagnostic performance of shear-wave elastography (SWE) for breast cancer and to determine whether the integration of SWE into BI-RADS with subcategories of category 4 improves the diagnostic performance. A total of 389 breast masses (malignant 120, benign 269) in 324 women who underwent SWE before ultrasound-guided core biopsy or surgery were included. The qualitative SWE feature was assessed using a four-colour overlay pattern. Quantitative elasticity values including the lesion-to-fat elasticity ratio (Eratio) were measured. Diagnostic performance of B-mode ultrasound, SWE, or their combined studies was compared using the area under the ROC curve (AUC). AUC of Eratio (0.952) was the highest among elasticity values (mean, maximum, and minimum elasticity, 0.949, 0.939, and 0.928; P = 0.04) and AUC of colour pattern was 0.947. AUC of combined studies was significantly higher than for a single study (P Shear-wave elastography showed a good diagnostic performance. Adding SWE features to BI-RADS improved the diagnostic performance and may be helpful to stratify category 4 lesions. • Quantitative and qualitative shear-wave elastography provides further diagnostic information during breast ultrasound. • The elasticity ratio (E ratio ) showed the best diagnostic performance in SWE. • E ratio and four-colour overlay pattern significantly differed between benign and malignant lesions. • SWE features allowed further stratification of BI-RADS category 4 lesions.

To compare the image quality, radiation dose, and diagnostic performance between low-dose (LD) and ultra-low-dose (ULD) lumbar-spine (L-spine) CT with iterative reconstruction (IR) for patients with chronic low back pain (LBP). In total, 260 patients with chronic LBP who underwent L-spine CT between November 2015 and September 2016 were prospectively enrolled. Of these, 143 underwent LD-CT with IR and 117 underwent ULD-CT with IR. The patients were divided according to their body mass index (BMI) into BMI1 (<22.9 kg/m{sup 2}), BMI2 (23.0-24.9 kg/m{sup 2}), and BMI3 (≥25 kg/m{sup 2}) groups. Two blinded radiologists independently evaluated the signal-to-noise ratio (SNR), qualitative image quality, and final diagnoses (lumbar disc disease and facet joint osteoarthritis). L-spine MRIs interpreted by consensus were used as the reference standard. All data were statistically analyzed. ULD protocol showed significantly lower SNR for all patients (p < 0.001) except the vertebral bodies and lower qualitative image quality for BMI3 patients (p ≤ 0.033). There was no statistically significant difference between ULD (sensitivity, 95.1-98.1%; specificity, 92.5-98.7%; accuracy, 94.6-98.0%) and LD protocols (sensitivity, 95.6-100%; specificity, 95.5-98.9%; accuracy, 97.4-98.1%), (all p≥0.1) in the BMI1 and BMI2; while dose was 60-68% lower with the ULD protocol. Interobserver agreements were excellent or good with regard to image quality and final diagnoses. For the BM1 and BMI2 groups, ULD-CT provided an acceptable image quality and exhibited a diagnostic accuracy similar to that of LD-CT. These findings suggest that it is a useful diagnostic tool for patients with chronic LBP who exhibit a BMI of <25 kg/m{sup 2}. (orig.)

In total, 260 patients with chronic LBP who underwent L-spine CT between November 2015 and September 2016 were prospectively enrolled. Of these, 143 underwent LD-CT with IR and 117 underwent ULD-CT with IR. The patients were divided according to their body mass index (BMI) into BMI1 (<22.9 kg/m 2 ), BMI2 (23.0-24.9 kg/m 2 ), and BMI3 (≥25 kg/m 2 ) groups. Two blinded radiologists independently evaluated the signal-to-noise ratio (SNR), qualitative image quality, and final diagnoses (lumbar disc disease and facet joint osteoarthritis). L-spine MRIs interpreted by consensus were used as the reference standard. All data were statistically analyzed. ULD protocol showed significantly lower SNR for all patients (p < 0.001) except the vertebral bodies and lower qualitative image quality for BMI3 patients (p ≤ 0.033). There was no statistically significant difference between ULD (sensitivity, 95.1-98.1%; specificity, 92.5-98.7%; accuracy, 94.6-98.0%) and LD protocols (sensitivity, 95.6-100%; specificity, 95.5-98.9%; accuracy, 97.4-98.1%), (all p≥0.1) in the BMI1 and BMI2; while dose was 60-68% lower with the ULD protocol. Interobserver agreements were excellent or good with regard to image quality and final diagnoses. For the BM1 and BMI2 groups, ULD-CT provided an acceptable image quality and exhibited a diagnostic accuracy similar to that of LD-CT. These findings suggest that it is a useful diagnostic tool for patients with chronic LBP who exhibit a BMI of <25 kg/m 2 . (orig.)

Chlamydia trachomatis (CT) infections in women can result in tubal pathology (TP). Worldwide 10-15% of all couples are subfertile, meaning they did not get pregnant after 1 year. Part of the routine subfertility diagnostics is the Chlamydia Antibody Test (CAT) to decide for laparoscopy or not in order to diagnose TP. The CAT positive and negative predictive value is such that many unneeded laparoscopies are done and many TP cases are missed. Addition of host genetic markers related to infection susceptibility and severity could potentially improve the clinical management of couples who suffer from subfertility. In the present study, the potential translational and clinical value of adding diagnostic host genetic marker profiles on the basis of infection and inflammation to the current clinical management of subfertility was investigated. This review provides an overview of the current state of the art of host genetic markers in relation to CT infection, proposes a new clinical diagnostic approach, and investigates how the Learning-Adapting-Leveling model (LAL, a public health genomic (PHG) model) can be of value and provide insight to see whether these host genetic markers can be translated into public health. This review shows that the preliminary basis of adding host genetic marker profiles to the current diagnostic procedures of subfertility is present but has to be further developed before implementation into health care can be achieved. CT infection is an example in the field of PHG with potential diagnostic to be taken up in the future in the field of subfertility diagnosis with a time line for integration to be dependent on enhanced participation of many stakeholders in the field of PHG which could be advanced through the LAL model.

To review the diagnostic and therapeutic challenges associated with treating isolated primary breast tuberculosis through discussion of our series of seven cases. Although breast is an uncommon site of occurrence of tuberculosis and isolated primary breast tuberculosis is an even rarer entity, its importance lies in distinguishing it from more common pathologies like abscesses or malignancy and avoiding unnecessary erroneous surgical intervention. The spectrum and presentation is wide and varied and we present our experience in managing seven such cases. A retrospective analysis of all the cases of histopathologically proven primary breast tuberculosis in the last three years at M.S. Ramaiah Hospital (2012-2014) was done. Analysis was in terms of mode of presentation, clinical features, diagnostic modalities used for evaluation and confirmation of the diagnosis, medical treatment and surgical intervention, if any. Special emphasis was placed on dilemmas in diagnosis and difficulties encountered during treatment. All cases were followed up till cure. Patients most commonly presented with a breast abscess, painful breast lumps and recurrent abscesses. Other foci of tuberculosis were ruled out in all of these patients. Majority were treated exclusively with anti-tubercular therapy (although regimens varied), but those with abscesses underwent incision and drainage. All cases were treated and followed up till cure. The challenges associated with primary breast tuberculosis are multiple, including which anti-tubercular therapy regimen to use, when to surgically intervene (as the breast is a cosmetically important area) and treating atypical mycobacteria. We provide a detailed discussion of the challenges we faced and review of literature.

The aim of this paper is to analyse, after clinical experience with a series of patients with established diagnoses and review of the literature, all relevant anamnestic features in order to build a simple diagnostic algorithm for vertigo in childhood. This study is a retrospective chart review. A series of 37 children underwent complete clinical and instrumental vestibular examination. Only neurological disorders or genetic diseases represented exclusion criteria. All diagnoses were reviewed after applying the most recent diagnostic guidelines. In our experience, the most common aetiology for dizziness is vestibular migraine (38%), followed by acute labyrinthitis/neuritis (16%) and somatoform vertigo (16%). Benign paroxysmal vertigo was diagnosed in 4 patients (11%) and paroxysmal torticollis was diagnosed in a 1-year-old child. In 8% (3 patients) of cases, the dizziness had a post-traumatic origin: 1 canalolithiasis of the posterior semicircular canal and 2 labyrinthine concussions, respectively. Menière's disease was diagnosed in 2 cases. A bilateral vestibular failure of unknown origin caused chronic dizziness in 1 patient. In conclusion, this algorithm could represent a good tool for guiding clinical suspicion to correct diagnostic assessment in dizzy children where no neurological findings are detectable. The algorithm has just a few simple steps, based mainly on two aspects to be investigated early: temporal features of vertigo and presence of hearing impairment. A different algorithm has been proposed for cases in which a traumatic origin is suspected.

The success in achieving peaceful fusion power depends on the ability to control a high temperature plasma, which is an object with unique properties, possibly the most complicated object created by humans. Over years of fusion research a new branch of science has been created, namely plasma diagnostics, which involves knowledge of almost all fields of physics, from electromagnetism to nuclear physics, and up-to-date progress in engineering and technology (materials, electronics, mathematical methods of data treatment). Historically, work on controlled fusion started with pulsed systems and accordingly the methods of plasma parameter measurement were first developed for short lived and dense plasmas. Magnetically confined hot plasmas require the creation of special experimental techniques for diagnostics. The diagnostic set is the most scientifically intensive part of a plasma device. During many years of research operation some scientific tasks have been solved while new ones arose. New tasks often require significant changes in the diagnostic system, which is thus a very flexible part of plasma machines. Diagnostic systems are designed to solve several tasks. As an example here are the diagnostic tasks for the International Thermonuclear Experimental Reactor - ITER: (1) Measurements for machine protection and basic control; (2) Measurements for advanced control; (3) Additional measurements for performance evaluation and physics. Every new plasma machine is a further step along the path to the main goal - controlled fusion - and nobody knows in advance what new phenomena will be met on the way. So in the planning of diagnostic construction we should keep in mind further system upgrading to meet possible new scientific and technical challenges. (author)

Multi-detector-row computed tomography angiography (MDCTA) plays an important role in the assessment of patients with suspected coronary artery disease. However, MDCTA tends to overestimate stenosis in calcified coronary artery lesions. The aim of our study was to evaluate the diagnostic performance of calcification-suppressed material density (MD) images produced by using a single-detector single-source dual-energy computed tomography (ssDECT). We enrolled 67 patients with suspected or known coronary artery disease who underwent ssDECT with rapid kilovolt-switching (80 and 140 kVp). Coronary artery stenosis was evaluated on the basis of MD images and virtual monochromatic (VM) images. The diagnostic performance of the two methods for detecting coronary artery disease was compared with that of invasive coronary angiography as a reference standard. We evaluated 239 calcified segments. In all the segments, the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy for detecting significant stenosis were respectively 88%, 88%, 75%, 95% and 88% for the MD images, 91%, 71%, 56%, 95% and 77% for the VM images. PPV was significantly higher on the MD images than on the VM images (P < 0.0001). Calcification-suppressed MD images improved PPV and diagnostic performance for calcified coronary artery lesions.

Our purpose was to retrospectively evaluate the incidence and morphologic features of diabetic mastopathy in a group of patients with diabetes, searching for specific sonographic characteristics of diabetic mastopathy. One hundred twenty diabetic patients underwent breast clinical examination, mammography, and sonography. All detected breast lesions were confirmed histopathologically. Breast lesions were found in 11 of the 120 patients (9%), including two cases of invasive ductal carcinomas and nine cases of diabetic mastopathy. In seven of those nine cases (77%), diabetic mastopathy appeared as a hypoechoic solid mass with irregular margins, inhomogeneous echotexture, and marked posterior shadowing. In the other two cases (23%), it appeared as a mildly inhomogeneous, hypoechoic solid mass. Diabetic mastopathy is a diagnostic challenge and needs to be suspected in all patients with diabetes mellitus. Imaging features are nonspecific and highly susggestive on breast sonography in most cases. Core-needle biopsy confirmation remains mandatory for a definitive diagnosis. © 2015 Wiley Periodicals, Inc.

To assess the safety and usefulness of ultrasonography-guided transthoracic cutting biopsy for lung lesions. Eighty-eight patients (66 men, 22 women, mean age 59 years) with lung lesions underwent an ultrasonography(USG)-guided transthoracic cutting biopsy. The final diagnosis was based on the findings of surgery and clinical and radiological follow-ups. The histopathologic results and diagnostic accuracy of cutting biopsy were determined. Also, the complication rate was statistically evaluated according to the mass size, number of biopsies, and the presence or absence of pleural effusion. Biopsy specimens were successfully obtained in all patients. 79 of 88 lesions (89.8%) were established by histopathology. The final diagnosis was malignant in 58 and benign in 28. The remaining 2 patients were lost to follow-up. Diagnostic sensitivity for malignant lesions was 89.6% (52/58) and that for benign lesions was 96.4% (27/28). Procedure-related complications occurred in 9 patients (10.2%) including pneumothorax (n = 2) and hemoptysis (n = 7). And there was no significant difference according to mass size, number of biopsies, or presence of pleural effusion. USG-guided transthoracic cutting biopsy is a useful and safe method for technically-feasible lung lesions
