    Full Text Available Objectives: Diagnostic laparoscopy has become an integral part of general surgical procedures with the recent advancements in laparoscopic technology. Since surgeons are more oriented in viewing and dissection of different intra-abdominal areas and are proficient in the definitive management of complications in the procedures, diagnostic laparoscopy may be better off in the hands of surgeons. Laparoscopy has proved to be an important tool in final minimally invasive exploration for selected medical patients with chronic abdominal disorders, the diagnosis of which remains uncertain despite employing the requisite laboratory and non-invasive imaging investigations. This retrospective study was done to evaluate the accuracy of elective diagnostic laparoscopy in patients with chronic abdominal disorders and its impact on the management of these patients. Methods: The records of 35 patients, admitted to Riyadh Medical Complex with chronic abdominal disorders and referred to the author by physicians for elective diagnostic laparoscopy from 1999 through 2004, were evaluated for the accuracy and impact of this procedure in the further management of these patients. All 35 patients were investigated by the referring physician. Investigations included hematology, biochemistry, radiology, ascitic fluid analysis, endoscopic and imaging studies and the Mantoux test. These investigations suggested abdominal tuberculosis in 22 patients and intra-abdominal malignancy in 13 patients. They were referred for elective diagnostic laparoscopy and tissue biopsy. Results: Diagnostic laparoscopy confirmed the diagnosis in all patients suspected of malignancy. In patients with suspected abdominal tuberculosis, the laparoscopic diagnosis and biopsy revealed tuberculosis (16 patients, liver cirrhosis (2 patients, Crohn′s disease (1 patient, and metastatic carcinoma of terminal ileum (1 patient. In 2 patients the procedure did not reveal any specific pathology. The

    Introduction: The role of diagnostic and therapeutic hystero-laparoscopy in women with infertility is well established. It is helpful not only in the identification of the cause but also in the management of the same at that time. Materials and Methods: In this study, the aim was to analyse the results of 203 women on whom laparoscopy for the evaluation of infertility was done. This study was carried out at a tertiary level hospital from 2005 to 2012. The study group included 121 women with primary infertility and 82 women with secondary infertility. Women with incomplete medical records and isolated male factor infertility were excluded from the study. Results: It was observed that tubal disease was the responsible factor in 62.8% women with primary infertility and 54.8% women with secondary infertility followed by pelvic adhesions in 33% and 31.5%, ovarian factor in 14% and 8.5%, pelvic endometriosis in 9.9% and 6.1% women respectively. Thus tubal factor infertility is still a major cause of infertility in developing countries and its management at an early stage is important to prevent an irreversible damage. At the same time, it also directs which couples would be benefited from assisted reproductive technologies (ART). PMID:25478408

    Full Text Available ABSTRACT: Chronic abdominal pain is a FREQUENTLY ENCOUNTERED pr oblem and abdominal tuberculosis is a very common cause of the same. Di agnostic laparoscopy is a highly sensitive, specific, and safe procedure for the early diagnosis of abdominal tuberculosis. The procedure is beneficial because it is minimally invasive and prov ides diagnostic benefit in terms of both visual appearances and tissue yield for histopathologi cal and cytological confirmation. We have performed an extensive retrospective study with 250 s ubjects and were able to justify the safety, sensitivity & early selection of laparoscopy as a procedure of choice to confirm tuberculosis in chronic abdominal pain.

    Full Text Available ABSTRACT: BACKGROUND : Chronic idiopathic pain syndromes are among the most challeng ing and demanding conditions to treat across the whole age spectrum. Potentially it can be unrewarding for both the patients and the medical team. Patients with chronic abdominal pain (CAP can undergo numerous diagnostic tests with failure to detect any s tructural or biochemical abnormality. This study was undertaken to assess the diagnostic and therapeutic role of laparoscopy in patients with unexplained chronic abdominal pain (UCAP. PATIENTS AND METHODS: Diagnostic laparoscopy was performed for 100 pati ents with UCAP not diagnosed by usual clinical examination and investigations . The pain in all patients was of unclear etiology despite all the investigative procedures. All patients were subjected to laparoscopic evaluation for their conditions. The findi ngs and outcomes of the laparoscopy were recorded and analyzed. RESULTS: UCAP is common in females (62% than in males. The most frequent laparoscopic findings detected were abdominal adhesions ( 30% , followed by pelvic inflammatory disease ( 25%, abdomina l tuberculosis (12%, chronic appendicitis (8%, mesenteric lymphadenitis (5% and diverticulosis (2%. In 18% of cases no identifiable cause could be found. Follow after 2 months revealed pain relief in 84% irrespective of cause of pain. CONCLUSION: Lapa r oscopy is an effective diagnostic and therapeutic modality in the management of patients with chronic abdominal pain.

    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.

    Full Text Available Background. The reported incidence of noncurative laparotomies for pancreatic cancer using standard imaging (SI techniques for staging remains high. The objectives of this study are to determine the diagnostic accuracy of diagnostic laparoscopy with ultrasound (DLUS in assessing resectability of pancreatic tumors. Study Design. We systematically searched the literature for prospective studies investigating the accuracy of DLUS in determining resectability of pancreatic tumors. Results. 104 studies were initially identified and 19 prospective studies (1,573 patients were included. DLUS correctly predicted resectability in 79% compared to 55% for SI. DLUS prevented noncurative laparotomies in 33%. Of those, the most frequent DLUS findings precluding resection were liver metastases, vascular involvement, and peritoneal metastases. DLUS had a morbidity rate of 0.8% with no mortalities. DLUS remained superior to SI when analyzing studies published only in the last five years (100% versus 81%, enrolling patients after the year 2000 (74% versus 58%, or comparing DLUS to modern multidimensional CT (100% versus 78%. Conclusion. DLUS seems to still have a role in the preoperative staging of pancreatic cancer. With its ability to detect liver metastases, vascular involvement, and peritoneal metastases, the use of DLUS leads to less noncurative laparotomies.

While the machines vary widely on diagnostic requirements, there are many similarities that were discovered. The following sections will attempt to point out the similarities and requirements for R&D for these future accelerators. To answer the Charge to the group we organized joint sessions with most of the machine groups and several of the technical groups. In addition, due to their overwhelming importance, we held a special session on position monitor systems. For each of the joint machine group sessions we generated a table of required diagnostic systems, selected the highest priority items using a ranking based on need and RD effort, and pondered a RD path leading from the present state of the technology to a system satisfying the requirement. We used the joint technical group sessions to collect up to date RD plans and to assess the applicability of new ideas in a broad range of topics. As required by our Charge, we have also tried to include promising new ideas.

    Full Text Available Assisted reproductive technologies are used to accelerate genetic gain and improve reproductive performances in farm animals, including small ruminants. This technologies include estrous synchronization, artifi cial insemination (AI using fresh, frozen or sexed semen, embryo transfer (ET using in vivo or in vitro produced embryos, and more advanced - cloning and production of transgenic animals. Diagnostic procedures, such as ultrasonography and laparoscopy, have been used as additional tools for monitoring the ovarian response to superovulatory treatment in donor animals as well as for AI and collection and transfer of embryos. The use of laparoscopy for assisted reproduction techniques in Macedonia commenced in the early 90’s, with the acquisition of a set of ,,Karl Storz” equipment. After the adoption of the required routine, our group has completed several scientifi c projects where laparoscopy was used for intrauterine inseminations as well as for recovery and transfer of embryos in both sheep andgoats. In the following period our group endeavored into introduction of laparoscopic insemination in the routine farm practice. Ovine intrauterine/intracornual insemination by frozen-thawed semen resulted with pregnancy rates of 45% and 60%, when AI was performed out of season and during the breeding season, respectively. In goats, this percentage occasionally peaked at 85%. The aim of this article is to review the status of implementation of laparoscopy in Assisted Reproduction Technologies (ART of small ruminants and to present our experience in this field.

    Full Text Available The spectrum of laparoscopic surgery in children has undergone a dramatic evolution. Initially used as a diagnostic modality for many pediatric urologists, complex as well as reconstructive procedures are now being performed laparoscopically. Laparoscopic orchiopexy and nephrectomy are well established and are being performed at many centers. Laparoscopic partial nephrectomy, adrenalectomy, and dismembered pyeloplasty series have reported shortened hospital stays and operative times that are comparable to that of open techniques or are decreasing with experience. The initial experiences with laparoscopic ureteral reimplantation and laparoscopic-assisted bladder reconstructive surgery have been described, reporting encouraging results with regards to feasibility, hospital stay, and cosmetic outcome. This report will provide a directed review of the literature to establish the current indications for laparoscopy in pediatric urologic surgery.

    Full Text Available : Infertility is not only a medical, but a serious social problem as well, especially in our country. Use of diagnostic and therapeutic laparoscopy in infertility has been a focus of attention in recent years and is found to be very effective method in evaluating these cases. Traditional way to assess the uterine cavity, tubal structures and tubal patency was hysterosalpingography, but it has now largely been superseded by hysteroscopy and laparoscopy. It is concluded that laparoscopy is useful in diagnosing cases with endometriosis, tubal factor infertility and exclusion of bilateral anatomical tubal pathology by diagnostic laparoscopy could avoid IVF treatment in these cases.

    Abdominal emergencies can also be operated on through the laparoscopic approach: the approach can be diagnostic laparoscopy, surgery assisted by laparoscopy or laparotomy directed according to the findings of the laparoscopy. The general contraindications refer above all to the state of haemodynamic instability of the patient and to seriously ill patients (ASA IV). In the absence of any specific counter-indications for the specific laparoscopic procedure to be carried out, many abdominal diseases requiring emergency surgery can be performed with the laparoscopic approach. The most frequent indications are appendicitis, acute colecistitis, gastroduodenal perforation, occlusion of the small intestine, and some abdominal traumas. With a correct selection of patients and the appropriate experience of the surgeon, the results are excellent and better than open surgery (less infection of the wound, complications, hospital stay and postoperative pain). A detailed explanation is given of the basic aspects of the surgical technique in the most frequent procedures of emergency laparoscopy.

    Full Text Available Introduction: Chronic pelvic pain (CPP is a common medical problem affecting women. Too often the physical signs are not specific. This study aims at determining the accuracy of diagnostic laparoscopy over clinical pelvic examination. Settings and Design: A retrospective study of patients who underwent diagnostic laparoscopy for CPP. Materials and Methods: The medical records of 86 women who underwent laparoscopic evaluation for CPP of at least 6-month duration were reviewed for presentation of symptoms, pelvic examination findings at the admission, operative findings and follow up when available. Statistical analysis used: McNemar Chi-square test for frequencies in a 2 x 2 table. Results: The most common presentation was acyclic lower abdominal pain (79.1%, followed by congestive dysmenorrhoea (26.7%. 61.6% of women did not reveal any significant signs on pelvic examination. Pelvic tenderness was elicited in 27.9%. Diagnostic laparoscopy revealed significant pelvic pathology in 58% of those who essentially had normal pervaginal findings. The most common pelvic pathology by laparoscopy was pelvic adhesions (20.9%, followed by pelvic congestion (18.6%. Laparoscopic adhesiolyis achieved pain relief only in one-third of the women. Conclusion: The study revealed very low incidence of endometriosis (4.7%. Overall clinical examination could detect abnormality in only 38% of women, where as laparoscopy could detect significant pathology in 66% of women with CPP. This shows superiority of diagnostic laparoscopy over clinical examination in detection of aetiology in women with CPP (P < 0.001. Adhesiolysis helps only small proportion of women in achieving pain control.

This shows superiority of diagnostic laparoscopy over clinical examination in detection of aetiology in women with CPP (P < 0.001). Adhesiolysis helps only small proportion of women in achieving pain control. PMID:21188008

    Full Text Available Abstract Background Adherential pathology is the most common cause of small bowel obstruction. Laparoscopy in small bowel obstruction does not have a clear role yet; surely it doesn't always represent only a therapeutic act, but it is always a diagnostic act, which doesn't interfere with abdominal wall integrity. Methods We performed a review without any language restrictions considering international literature indexed from 1980 to 2007 in Medline, Embase and Cochrane Library. We analyzed the reference lists of the key manuscripts. We also added a review based on international non-indexed sources. Results The feasibility of diagnostic laparoscopy is high (60–100%, while that of therapeutic laparoscopy is low (40–88%. The frequency of laparotomic conversions is variable ranging from 0 to 52%, depending on patient selection and surgical skill. The first cause of laparotomic conversion is a difficult exposition and treatment of band adhesions. The incidence of laparotomic conversions is major in patients with anterior peritoneal band adhesions. Other main causes for laparotomic conversion are the presence of bowel necrosis and accidental enterotomies. The predictive factors for successful laparoscopic adhesiolysis are: number of previous laparotomies ≤ 2, non-median previous laparotomy, appendectomy as previous surgical treatment causing adherences, unique band adhesion as phatogenetic mechanism of small bowel obstruction, early laparoscopic management within 24 hours from the onset of symptoms, no signs of peritonitis on physical examination, experience of the surgeon. Conclusion Laparoscopic adhesiolysis in small bowel obstruction is feasible but can be convenient only if performed by skilled surgeons in selected patients. The laparoscopic adhesiolysis for small bowel obstruction is satisfactorily carried out when early indicated in patients with a low number of laparotomies resulting in a short hospital stay and a lower postoperative

    2015-01-01

    Objectives Cartilage fatigue, due to mechanical work, may account for precocious development of degenerative joint disease in the temporomandibular joint (TMJ). This study compared energy densities (mJ/mm3) in TMJs of three diagnostic groups. Setting and Sample Population Sixty-eight subjects (44 women, 24 men) gave informed consent. Diagnostic criteria for temporomandibular disorders (DC/TMD) and imaging were used to group subjects according to presence of jaw muscle or joint pain (+P) and bilateral disc displacement (+DD). Material and Methods Subjects (+P+DD, n=16; −P+DD, n=16; and −P−DD, n=36) provided cone-beam computed tomography and magnetic resonance images, and jaw tracking data. Numerical modeling was used to determine TMJ loads (Fnormal). Dynamic stereometry was used to characterize individual-specific data of stress-field dynamics during 10 symmetrical jaw closing cycles. These data were used to estimate tractional forces (Ftraction). Energy densities were then calculated as W/Q(W=workdoneormechanicalenergyinput=tractionalforce×distanceofstress-fieldtranslation,Q=volumeofcartilage). ANOVA and Tukey-Kramer post-hoc analyses tested for intergroup differences. Results Mean ±standard error energy density for the +P+DD group was 12.7±1.5 mJ/mm3 and significantly greater (all adjusted p<0.04) when compared to −P+DD (7.4±1.4 mJ/mm3) and −P−DD (5.8±0.9 mJ/mm3) groups. Energy densities in −P+DD and −P−DD groups were not significantly different. Conclusion Diagnostic group differences in energy densities suggest that mechanical work may be a unique mechanism which contributes to cartilage fatigue in subjects with pain and disc displacement.

    Full Text Available Background. The aim of this study was to assess the share of organic changes in patients with chronic pelvic pain (CPP as well as evaluate the need for invasive CPP diagnosticslaparoscopy.Methods. The data for the analysis were gathered retrospectively from the descriptions of 287 CPP patients who were treated at the Clinic of Gynaecology in Ljubljana from 1993 to 1999. In this analysis the share of laparoscopically established organic causes of CPP was assessed and the findings of invasive (laparoscopy and non-invasive diagnostics (clinical status and ultrasound were compared.Results. Out of 287 patients, 272 underwent laparoscopy, 7 underwent laparotomy while 8 were only observed. As regards organic CPP causes, an organic cause was established in 70.7% patients through laparoscopy. The most frequently observed phenomena were adhesions, namely in 97 (35.7% patients, endometriosis in 68 (25.0% and pelvic varices in 29 (10% patients.By comparing the results of invasive and non-invasive diagnostics it was established that up to three times more organic changes – a possible cause of CPP – can be discovered through laparoscopy than through the use of non-invasive diagnostics methods.Conclusions. Laparoscopy is considered to be the most reliable method of diagnostics and detection of organic causes of CPP. An adequate psychological treatment within a multidisciplinary approach is necessary in patients in whom an organic cause of CPP can not be discovered in their genital tract.

  18. Appendagitis following Diagnostic Laparoscopy and Laparoscopic Appendicectomy

    2016-01-01

    Full Text Available Appendagitis is an uncommon clinical entity, often not recognised, and mistaken for more serious infective conditions. We describe a proven case of appendagitis which occurred after confirmed appendicitis. We postulate that this condition can coexist with appendicitis and indeed may be the result of coinflammation. This has several implications. Firstly, clinicians must retain an index of suspicion for this condition in a patient with localised abdominal pain which occurs after appendicitis. Secondly, it would be reasonable to suggest careful examination of colocated appendages in a patient with an otherwise normal-appearing appendix. Treatment might require laparoscopic resection, as performed in this case.

    This study compared adult women with childhood ADHD to adult women without childhood ADHD and to adult men with childhood ADHD. The participants, all from a larger longitudinal study, included 30 women and 30 men (approximately age 23 to 24) with childhood ADHD, and 27 women without ADHD. Women with childhood ADHD were matched to comparison women on age, ethnicity, and parental education, and to men with childhood ADHD on age, ethnicity, and IQ. Self- and parent-reports of internalizing, interpersonal, academic, and job impairment, as well as substance use and delinquency indicated group differences on measures of self-esteem, interpersonal and vocational functioning, as well as substance use. Follow-up planned comparison tests revealed that almost all of these differences emerged by diagnostic status, and not by gender. This study adds to research on the negative adult outcomes of ADHD and demonstrates that the outcomes of men and women with childhood ADHD are relatively similar.

    Full Text Available Background: To estimate the prevalence of genital tuberculosis in women with idiopathic chronic pelvic pain on laparoscopy, correlate laparoscopic findings with microbiological and histological diagnosis of tuberculosis and assess the response to anti tubercular treatment (ATT in these cases. Method: In a prospective cohort study, fifty women with idiopathic chronic pelvic pain were enrolled. Diagnostic laparoscopy was done in all women and fluid from pouch of Douglas and/or saline washings were sent for acid fast bacilli (AFB smear, conventional and rapid culture and DNA polymerase chain reaction (PCR analysis for diagnosis of genital TB. The results of these tests were analyzed and agreement with laparoscopy was assessed using Kappa statistics. Pain scores using visual analogue scale were compared before and after treatment. Results: Pelvic pathology was present in 44 (88% women of idiopathic chronic pelvic pain, with a 34% prevalence rate of genital tuberculosis. Pelvic inflammation was associated with positive peritoneal fluid PCR (n = 4 and AFB culture (n = 3. Acid fast bacilli PCR had substantial agreement (kappa statistics = 0.716 with visual findings at laparoscopy. There was a significant reduction in pain scores after treatment. Conclusion: Genital tuberculosis contributes to one-third cases of chronic pelvic pain. Pelvic inflammation is an early feature of genital TB and peritoneal fluid PCR has the best co-relation with laparoscopic findings of genital tuberculosis.

  1. Group-as-a-whole as a context for studying individual behaviour: A group diagnostic intervention

    Directory of Open Access Journals (Sweden)

    Dirk J. Geldenhuys

    2012-01-01

    Full Text Available Orientation: Traditionalists view group interventions from three perspectives: singletons, dyads and whole groups. The focus of this research was on interventions from the third perspective, that of the whole group, using a systems psychodynamic stance. Research purpose: The purpose of the research was to use group-as-a-whole to study individual behaviour in organisations.Motivation for the study: Team research and practice is not on a par with the complexities that teams actually experience. Traditional group interventions use humanistic and functionalistic paradigms that do not consider the unconscious functioning of groups. Interventions that use the system psychodynamic paradigm could address these dynamics because they study behaviour of individual group members in the context of the group-as-a-whole. Research design, approach and method: The researcher conducted action research in a publishing company. He used purposive sampling and analysed the data using qualitative content analysis.Main findings: The researcher found that the group-as-a-whole partly explains the behaviour of team members and that intervening from this perspective could improve negative relationships.Practical/managerial implications: Managers can use interventions that use the groupas- a-whole concept as a diagnostic intervention to study and possibly change the complex behavioural issues that team members experience.Contribution/value-add: The findings give one an understanding of the behaviour of individual group members when one views it from a systems psychodynamic stance. Furthermore, the researcher proposes a group diagnostic intervention that will allow some of the root causes of poor interpersonal behaviour to surface and group members to diagnose and take ownership of their own behaviour.

    To evaluate the feasibility and usefulness of gasless laparoscopy-assisted distal gastrectomy except when treating obese patients compared with open distal gastrectomy for early cancer. We treated 92 patients with distal gastrectomy for early gastric cancer consecutively. Patients with massive submucosal invasion and/or LN swelling were allocated for the open method, and patients with slightly invasive submucosal cancer were allocated for gasless laparoscopy-assisted surgery. As exceptions we employed open surgery for overweight patients and gasless laparoscopy for elderly and/or feeble patients. We attempted to perform open and laparoscopy-assisted surgery on 52 and 40 patients, respectively. Three cases in the laparoscopy-assisted group were converted to open surgery because of obesity. The age was older and BMI was lower in the laparoscopy-assisted group. In terms of operative time and blood loss as well as postoperative recovery, the results for the laparoscopy-assisted group were superior to those of the open surgery group. There were no cases of cardiopulmonary complications for the laparoscopy-assisted group. Gasless laparoscopy-assisted distal gastrectomy is feasible and useful for early gastric cancer except when treating obese patients.

    AIM: To investigate the diagnostic and therapeutic value of laparoscopy in patients with massive small intestinal bleeding.METHODS: Twenty-two patients with massive small intestinal bleeding and hemodynamic alteration underwent laparoscopic laparotomy in our unit from December 2002 to April 2005. Post pathologic sites were found, laparoscopy- or laparoscopy-assisted part small intestinal resection including pathologic intestinal site and enteroanastomosis was performed in all these patients.RESULTS: The bleeding sites were successfully detected by laparoscopy in all these 22 patients. Massive small intestinal bleeding was caused by jejunum benign stromal tumor in 8 cases, by jejunum potential malignant stromal tumor in 5 cases, by jejunum malignant stromal tumor in 1 case, by Mechel's diverticulum in 5 cases,by small intestinal vascular deformity in 2 cases, and by ectopic pancreas in 1 case. A total of 16 patients underwent laparoscopy-assisted enterectomy and enteroanastomosis of small intestine covering the of the diseased segment under laparoscope. No surgical complications occurred and the outcome was satisfactory.CONCLUSION: Laparoscopy in diagnosis and treatment of massive small intestinal bleeding is noninvasive with less pain, short recovery time and definite therapeutic efficacy.

    2004-08-01

    The purpose of this report was to describe the evidence for the benefits of laparoscopic surgery in obese patients, to review the physiologic abnormalities that are associated with obesity, and to explore surgical techniques that will enable surgeons to perform laparoscopy successfully in obese patients. This article is a review of the available literature on obesity, the physiologic changes that occur in obese patients, and the impact of these changes on laparoscopy outcomes. Obesity is associated with sudden death and a wide range of morbid conditions such as hypertension, atherosclerosis, angina, chronic obstructive disease, and diabetes mellitus. Recent studies have demonstrated that obese patients who undergo laparoscopy have shorter hospital stays, less postoperative pain, and fewer wound infections when compared with obese patients who undergo laparotomy. Laparoscopy patients also have fewer postoperative ileus and fevers. With thorough preparation and careful preoperative evaluation, laparoscopy can be performed safely and is the preferred surgical method in obese patients.

    Objective: To detect the effect of intra-peritoneal instillation of local anesthetic with or without NSAIDs on pain relief after gynecological laparoscopy. Methods: Seventy five patients scheduled for laparoscopy were included in the study and randomly divided into three groups. At the end of the laparoscopic procedure, 100 mL normal saline in the first group, or 100 mL normal saline contains 200 mg lidocaine in the second group, or 100 mL normal slaine containing 200 mg lidocaine and 20 mg tenoxicam in the third group were splashed into the pelvis by the surgeon. Post-operative pain were monitored and compared. Results: The incidence and severity of immediate postoperative shoulder pain reduced from 44% of patients scoring 2-5 in saline group to 16% scoring 2-3 in lidocaine group and 8% scoring 2-3 in lidocaine-tenoxicam group. Compared with saline group, abdominal pain scores were significantly lower in lidocaine group and lidocaine-tenoxicam group over 24 hours after surgery. At 12 and 24 hours after surgery, abdominal pain scores were significantly reduced in lidocaine-tenoxicam group compared with lidocaine group. No pain on deep respiration was reported in 84%, and 68% in lidocaine-tenoxicam and lidocaine groups respectively compared to 12% in those in the saline group. The mean time to first request for analgesia was increased from (2.3 ±1.9) hours in saline group to (4.4 ± 2.4) hours in lidocaine group and to (8.3 ± 10.2) hours in lidocaine-tenoxicam group. Conclusion: Intraperitoneal balanced analgesia (local anesthetics ± NSAIDS) is a simple and safe technique for analgesia following gynaecological Laparoscopy.

  10. Occasional finding of mesenteric lipodystrophy during laparoscopy: A difficult diagnosis

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Mesenteric lipodystrophy is a rare pathological condition affecting the mesentery. Its initial presentation is typically asymptomatic. Pathological characteristics are unspecific, and generally attributed to inflammation, unless the diagnosis is suspected. Laparoscopy done for other reasons has been, as in this case, unsuccessful in providing evidence for the correct diagnosis, thus requiring laparotomy due to lack of diagnostic tissue. After 6 mo no further medical therapy is required, as the patient remains asymptomatic. Discussion of this case and a brief review of the literature are presented in the following paragraphs.

    2003-02-01

    Urology has continuously embraced novel technologies like laparoscopy that reduce patient morbidity yet maintain an excellent standard of care. Because of limitations on maneuverability, operative vision, manual dexterity, and tactile sense, laparoscopy can be more difficult to perform than corresponding tasks in open surgery. To potentially increase clinical applicability of laparoscopy, robots that enhance operative performance have recently been introduced for a variety of laparoscopic procedures such as laparoscopic radical prostatectomy, pyeloplasty, and even laparoscopic cystectomy and neobladder construction. While these robots have generated excitement and many robotic applications have been described, the benefit of the advanced technology in expanded series of patients remains largely unknown. In addition, the ability of telerobotics to be used by surgeons inexperienced in conventional laparoscopy is also poorly understood. This review compares current features of available robots, advantages and limitations of robots, the emerging clinical applications, and the future potential of robotics in urology.

    The introduction of laparoscopy in the surgeon’s armamentarium was in fact a “revolution in the history of surgery”. Since this technique involves insufflation of carbon dioxide it produces several pathophysiological changes which have to be understood by the anaesthesiologist who can modify the anaesthesia technique accordingly. Advantages of laparoscopy include reduced pain, small scars and early return to work. Certain complications specific to laparoscopic surgery are due to carboperitone...

    Paediatric urology often presents challenging scenarios. Magnetic resonance urography (MRU) and laparoscopy are increasingly used. We retrospectively studied children affected by a disease of the upper urinary tract who after MRU were elected for laparoscopic treatment. This pictorial essay draws on our experience; it illustrates some specific MRU findings and highlights the usefulness of MRU for the diagnosis of upper urinary tract pathology in children. It also offers some examples of the potential additional diagnostic information provided by laparoscopy as well as its therapeutic role.

    Sirota, Ido

    2014-01-01

    Background and Objectives: To determine perioperative outcome differences in patients undergoing robotic-assisted laparoscopic surgery (RALS) versus conventional laparoscopic surgery (CLS) for advanced-stage endometriosis. Methods: This retrospective cohort study at a minimally invasive gynecologic surgery center at 2 academically affiliated, urban, nonprofit hospitals included all patients treated by either robotic-assisted or conventional laparoscopic surgery for stage III or IV endometriosis (American Society for Reproductive Medicine criteria) between July 2009 and October 2012 by 1 surgeon experienced in both techniques. The main outcome measures were extent of surgery, estimated blood loss, operating room time, intraoperative and postoperative complications, and length of stay, with medians for continuous measures and distributions for categorical measures, stratified by body mass index values. Robotically assisted laparoscopy and conventional laparoscopy were then compared by use of the Wilcoxon rank sum, χ2, or Fisher exact test, as appropriate. Results: Among 86 conventional laparoscopic and 32 robotically assisted cases, the latter had a higher body mass index (27.36 kg/m2 [range, 23.90–34.09 kg/m2] versus 24.53 kg/m2 [range, 22.27–26.96 kg/m2]; P laparoscopy patients. After body mass index stratification, obese patients varied in operating room time (282.5 minutes [range, 224–342 minutes] for robotic-assisted laparoscopy versus 174 minutes [range, 130–270 minutes] for conventional laparoscopy; P laparoscopy groups. Conclusion: Despite a higher operating room time, robotic-assisted laparoscopy appears to be a safe minimally invasive approach for patients, with all other perioperative outcomes, including intraoperative and postoperative complications, comparable with those in patients undergoing conventional laparoscopy.

    There are two methods for ventilation in gynecological laparoscopy: volume-controlled ventilation (VCV) and pressure-controlled ventilation (PCV). To compare the lung mechanics, hemodynamic response and arterial blood gas analysis and gas exchange of two modes of VCV and PCV using laryngeal mask airway (LMA) at different time intervals. Sixty infertile women referred for diagnostic laparoscopy, based on ventilation mode, were randomly divided into two groups of VCV (tidal volume: 10 ml/kg) and PCV. In the PCV group, ventilation was initiated with a peak airway pressure (tidal volume: 10 ml/kg, upper limit: 35 cm H2O). In both groups, the arterial blood samples were taken in several time intervals (5, 10 and 15 min after LMA insertion) for blood gas evaluation. Also the lung mechanics parameters were continuously monitored and were recorded at different time intervals. There were no significant differences for patient's age, weight, height and BMI in two groups. The peak and plateau airway pressure were significantly higher in VCV group compared to PCV group 5 and 10 min after insertion of LMA. PaO2 was significantly higher after 10 and 15 min in VCV group compared to PCV group (p=0.005 and p=0.03, respectively). PaCO2 showed significant increase after 5 min in PCV group, but the differences were not significant after 10 and 15 min in two groups. The end tidal CO2 showed significant increase after 10 and 15 min in VCV compared to PCV group. Both VCV and PCV seem to be suitable for gynecological laparoscopy. However, airway pressures are significantly lower in PCV compared to VCV.

    This study aimed to compare the safety and efficacy of laparoscopy and laparotomy in the surgical treatment of early endometrial cancer, especially in obese women. The results obtained after laparoscopic surgical treatment of early endometrial cancer (International Federation of Gynecology and Obstetrics (FIGO) stage 1 or 2) in patients between 1996 and 2007 were compared with an age- and tumour-matched historical group of patients treated with laparotomy between 1988 and 1996. All the patients underwent hysterectomy, bilateral salpingo-oophorectomy, and pelvic + or - paraaortic lymphadenectomy. Both groups included 120 patients with a preoperative diagnosis of early endometrial cancer. The postoperative diagnosis was endometrial cancer stage 1 or 2 for 89% of the cases in both groups. The mean operating time was 170 min for the laparotomy group compared with 178 min for the laparoscopy group (nonsignificant difference). The estimated intraoperative blood loss was significantly greater in the laparotomy group, and the hospital stay was significantly shorter in the laparoscopy group. The results show that early endometrial cancer can be treated effectively by laparoscopy. Because of this study's retrospective design, the results should be interpreted with caution. However, the advantages of this method for obese patients are evident. The age and weight of these patients should not be used as a contraindication for laparoscopy.

    Full Text Available Background : Chronic abdominal pain is a difficult complaint. It leads to evident suffering and disability, both physically and psychologically. Many diagnostic and therapeutic procedures have been described in literature, but with little proof or evidence of success. Laparoscopy is one of the modalities that could be of benefit in such cases. We aim to evaluate the diagnostic and therapeutic value of laparoscopy in cases with chronic abdominal pain. Materials and Methods : Thirty patients with chronic abdominal pain were included in this prospective descriptive cross-sectional study. The pain in all patients was of unclear etiology despite all the investigative procedures. All patients were subjected to laparoscopic evaluation for their conditions. The findings and outcomes of the laparoscopy were recorded and analyzed. Results : The most common site of pain was the periumbilical region (30%. A definitive diagnosis was made in 25 patients (83.3%, while five patients (16.7% had no obvious pathology. Adhesions were the most common laparoscopic findings (63.3% followed by appendiceal pathology (10%, hernia (3.3%, gall bladder pathology (3.3%, and mesenteric lymphadenopathy (3.3%. Postoperatively, pain relief was achieved in 24 patients (80% after two months. Conclusion : Laparoscopy is an effective diagnostic and therapeutic modality in the management of patients with chronic abdominal pain.

    Laparoscopy simulation offers realistic complexity of tasks and required skills, and helps to develop competencies. However the relationship of stress to the experience has not been comprehensively explored. Objectives were: 1) to evaluate stress level before and during laparoscopy in surgery interns (PGY-1) and surgery residents (PGY-2); 2) to evaluate performance in simulated laparoscopy in both groups; 3) to study the correlation between stress pathways themselves and to study which factors mediate the relationship between stress and performance. Seven PGY-1 (didactic course plus 2-hour hands-on session) and 6 PGY-2 who usually operate by laparoscopy were included. Performance assessment used the MISTELS scale. Salivary cortisol (SC) was measured the day prior (T0) to simulation, and immediately before (T1), and after the session (T2). Electrophysiological indicators of stress were assessed by Holter: heart rate (HR) and its variability (pNN50) at the same time. Perceived stress was determined at T1. All parameters were similar at T0. Regarding the whole study population, simulation induced stress. However response varied by subgroups. For PGY-1, levels of SC, HR and pNN50 were similar between T0 and T1. Afterwards, SC and HR significantly increased with a parallel decrease in pNN50 at T2. For PGY-2, a significant increase in HR and decrease in pNN50 were observed from T0 to T1, and remained stable at T2. No change in SC level or perceived stress was noted. Performance score was significantly higher in PGY-2. Stress patterns were not correlated between each other but a correlation was found between electrophysiological parameters and performance. Two stress patterns were identified: PGY-1 exhibited an increase in stress level during the procedure, whereas in PGY-2 it occurred prior to the procedure. This suggests that the impact of simulation on stress parameters might be different according to the experience of the learners.

    years. The aim of this article is to report the initial experience from a university hospital in the laparoscopic management of penetrating abdominal traumas. METHODS: In a 3-year period, laparoscopy was performed in 37 patients who were hemodynamically stable and sustained penetrating abdominal trauma. Medical records were reviewed and the evaluation was conducted to determine indications for laparoscopy, associated injuries, the need for exploration, lenght of hospital stay and complications. RESULTS: There were 18 (48.6% positive and 19 (51.4% negative diagnostic laparoscopies (DL. In patients with positive DL, 8 (44.4% underwent exploratory laparotomy. In this group, all of them had either therapeutic laparotomy or laparotomy for better lesion identification. There were 10 (55.6% positive DLs, in whom laparotomy was not performed. Four of them had their injuries repaired laparocopically, hepatorraphy (n=2 and diaphragmatic repairs (n=2. The other ones had isolated nonbleeding injuries, and nontherapeutic laparotomy was successfully avoided. Patients were allowed a diet in the first postoperative day and the mean postoperative hospital stay was 3.8 days. CONCLUSION: Our initial experience confirms that laparoscopy is a good method of evaluation and treatment for penetrating trauma. The morbidity from an unnecessary laparotomy may be minimized when the procedure is well indicated, and treatment can be performed successfully in selected cases.

    To assess the safety and feasibility of total laparoscopy distal gastrectomy (TLDG). This meta-analysis was conducted between April and July 2013 in Sichuan Cancer Hospital, Chengdu, China. We searched PubMed, EMBASE and China Knowledge Resource Integrated Database updated until May 2013. Eight retrospective studies and one prospective study involving 2,046 total patients were included. The results showed that TLDG was associated with lower blood loss (mean difference=-22.39, p=0.04). and a greater number of harvested lymph nodes (mean difference=2.74, p=0.02). There was no significant difference between the 2 groups in operation time, time to first flatus, length of postoperative hospital stay, and postoperative complications. Compared with laparoscopy-assisted distal gastrectomy, TLDG resulted in reduced blood loss, and a greater number of harvested lymph nodes. Total laparoscopy distal gastrectomy is safe and feasible for gastric cancer.

    The aim of this study is to verify if the surgical approach (laparoscopy/laparotomy/vaginal) in stage-I endometrial cancer treatment, may have effects on intra- and post-operative outcomes and on the patient's quality of life. The study group consisted of patients with histological diagnosis of type-I endometrial adenocarcinoma, stage-I. They were divided into three groups according to surgical approach chosen (laparotomic/laparoscopic/vaginal). Every patient answered a telephone health survey (SF-36) at 30 and 180 days post-surgery. Surgical-operating times, hospitalization length and short/long-term complications after surgery were also compared. The SF-36 survey revealed a better performance status in patients who underwent laparoscopy as compared to those who received laparotomy or vaginal surgery. We found significantly better results considering General Health, Physical Functioning, Role-Physical and Bodily Pain in the laparoscopy group after 30 and 180 days. Patients who underwent laparoscopy had significantly shorter hospitalization and less post-operative complications even if laparoscopy required significantly longer surgical-operating times compared to vaginal surgery. Our data confirm the superiority of the laparoscopic approach respect to the laparotomic and vaginal ones both in term of hospitalization length and post-operative complications.

    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.).

Methods This was a systematic review of randomized controlled trials, which included studies retrieved from four databases (MEDLINE, Embase, Cochrane and LILACS, using a combination of the terms (Hernia, Ventral and (Laparoscopy and (Laparotomy. Results Six randomized trials were included, totaling 566 patients, 283 in the Laparoscopy group and 283 in the Laparotomy group. Laparoscopy reduced the risk of infection of the surgical wound (NNT = 5 and seroma formation (NNT = 13 and less length hospitalization (P = 0.02 compared to laparotomy in the correction of ventral hernias. Furthermore, laparoscopy increased the incidence of enterotomy (NNH = 25 and post operative pain (NNH = 8 and longer surgical time (P = 0.0009 when compared with laparotomy. There was no difference related to abscess (P = 0.79, hematoma (P = 0.43 and recurrency of ventral hernias (P = 0.25. Conclusions In the correction of ventral hernias, the use of laparoscopic technique is effective to reduce infections of the surgical wound and seroma formation, as well as, decrease the length hospitalization.

    Full Text Available Medical researchers endeavor to identify potentially useful biomarkers to develop marker-based screening assays for disease diagnosis and prevention. Useful summary measures which properly evaluate the discriminative ability of diagnostic markers are critical for this purpose. Literature and existing software, for example, R packages nicely cover summary measures for diagnostic markers used for the binary case (e.g., healthy vs. diseased. An intermediate population at an early disease stage usually exists between the healthy and the fully diseased population in many disease processes. Supporting utilities for three-group diagnostic tests are highly desired and important for identifying patients at the early disease stage for timely treatments. However, application packages which provide summary measures for three ordinal groups are currently lacking. This paper focuses on two summary measures of diagnostic accuracy—volume under the receiver operating characteristic surface and the extended Youden index, with three diagnostic groups. We provide the R package DiagTest3Grp to estimate, under both parametric and nonparametric assumptions, the two summary measures and the associated variances, as well as the optimal cut-points for disease diagnosis. An omnibus test for multiple markers and a Wald test for two markers, on independent or paired samples, are incorporated to compare diagnostic accuracy across biomarkers. Sample size calculation under the normality assumption can be performed in the R package to design future diagnostic studies. A real world application evaluating the diagnostic accuracy of neuropsychological markers for Alzheimer’s disease is used to guide readers through step-by-step implementation of DiagTest3Grp to demonstrate its utility.

We also evaluated short-term and oncologic outcomes after laparoscopy and open surgery.Methods: A total of 100 consecutive stage IV patients undergoing open (n=61 or laparoscopic (n=39 major resection were analyzed. There were four cases (10% of conversion to laparotomy in the laparoscopy group.Results: Pathological T4 tumors (56% vs 26%, primary colon cancers (74% vs 51%, and larger tumor diameter (6 vs 5 cm were more commonly managed with open surgery. Right colectomy was more common in the open surgery group (39% and low anterior resection was more common in the laparoscopy group (39%, P=0.002. Hepatic metastases in segments II, III, IVb, V, and VI were more frequently resected with laparoscopy (100% than with open surgery (56%, although the difference was not statistically significant. In colon and rectal cancers, mean operative time and 30-day complication rates of laparoscopy and open surgery did not differ. In both cancers, mean time to soft diet and length of hospital stay were shorter in the laparoscopy group. Mean time from surgery to chemotherapy commencement was significantly shorter with laparoscopy than with open surgery. In colon and rectal cancers, 2-year cancer-specific and progression-free survival rates were similar between the laparoscopy and open surgery groups.Conclusion: Based on our findings, laparoscopy can be selected as an initial approach in patients with a primary tumor without adjacent organ invasion and patients without primary tumor-related symptoms.

    The introduction of laparoscopy in the surgeon's armamentarium was in fact a "revolution in the history of surgery". Since this technique involves insufflation of carbon dioxide it produces several pathophysiological changes which have to be understood by the anaesthesiologist who can modify the anaesthesia technique accordingly. Advantages of laparoscopy include reduced pain, small scars and early return to work. Certain complications specific to laparoscopic surgery are due to carboperitoneum and increased intra-abdominal pressure. Venous air embolism, although very rare, can be lethal if not managed promptly. Other complications include subcutaneous emphysema, haemodynamic compromise and arrhythmias. Although associated with minimal postoperative morbidity, postoperative pain, nausea and vomiting can be quite problematic. The limitations of laparoscopy have been overcome by the introduction of robotic surgery. There are important implications for the anaesthesiologist during robotic surgeries which have to be practiced accordingly. Robotic surgery has a learning curve for both the surgeon and the anaesthesiologist. The robot is bulky, and cannot be disengaged after docking. Therefore it is important that the anaesthetized patient remains immobile throughout surgery and anaesthesia is reversed only after the robot has been disengaged at the end of surgery. Advances in laparoscopy and robotic surgery have modified anaesthetic techniques too.

  12. Pediatric laparoscopy: Facts and factitious claims

    2010-01-01

    Full Text Available Background: Pediatric laparoscopy (LS is claimed to be superior to open surgery (OS. This review questions the scientific veracity of this assertion by systematic analysis of published evidences comparing LS versus OS in infants and children. Materials and Methods: Search of PubMed data base and the available literature on pediatric LS is analyzed. Results: One hundred and eight articles out of a total of 426 papers were studied in detail. Conclusions: High quality evidences indicate that LS is, at the best, as invasive as OS; and is at the worst, more invasive than conventional surgery. There are no high quality evidences to suggest that LS is minimally invasive, economically profitable and is associated with fewer complications than OS. Evidences are equally distributed for and against the benefits of LS regarding postoperative pain. Proof of cosmetic superiority of LS or otherwise is not available. The author concludes that pediatric laparoscopy, at the best, is simply comparable to laparotomy and its superiority over the latter could not be sustained on the basis of available scientific evidences. Benefits of laparoscopy appear to recede with younger age. Concerns are raised on the quick adoption, undue promotion and frequent misuse of laparoscopy in children.

    Holter monitoring is routinely used in patients referred for the evaluation of syncope, but its diagnostic value in different patient groups is unclear, as is its impact on device implantation (pacemaker or cardioverter-defibrillator). To determine the diagnostic yield of Holter monitoring in the routine evaluation of syncope, and its impact on subsequent device implantation. Retrospective record review. We reviewed all Holter studies in patients referred with syncope between 2000 and 2005. Strict criteria were applied to determine whether a study was diagnostic. The diagnostic value of Holter monitoring (overall and in five subgroups: age, gender, structural heart disease, ejection fraction, medication) and its impact on the implantation of devices, were determined. Of 4877 Holter studies, 826 were performed in patients with syncope (age 72 +/- 15 years): 71 (8.6%) were considered to explain the syncope. Structural heart disease, ejection fraction and age were significant predictors of a diagnostic study (all p Holter did not explain their syncope, after mean 7 months, whereas 45 patients (5.4%) received a pacemaker based on the Holter results (p = 0.32). The overall diagnostic yield of Holter monitoring in the evaluation of syncope was 8.6%, with dramatic differences between subgroups. Our data suggest that the impact of Holter monitoring on device implantation is generally overestimated.

    The aim of this study was to investigate the feasibility and safety of laparoscopic management of obese women with early stage endometrial cancer and to compare the surgical outcome, cost, hospital stay, recall of postoperative pain control, time to return to full activity and to work, and overall satisfaction among these women and those managed by laparotomy. We conducted a prospective study over 2 years applying laparoscopic surgery to all women with clinical stage I endometrial cancer and body mass indices (BMIs) between 28.0 and 60.0 who can tolerate such surgery. As a control, we used women with clinical stage I endometrial cancer and similar BMIs who underwent laparotomy in the previous 2 years. Both groups were compared in their characteristics, surgical outcome, cost, and hospital stay, and interviewed regarding time to recovery, recall of postoperative pain control, and overall satisfaction with their management. Forty of 42 obese women who presented with clinical stage I endometrial cancer during the study period were offered laparoscopic surgery. The procedure was converted to laparotomy in 3 (7.5%) patients. Laparoscopic surgery was thus successful in 88.1% of all obese women. There was no significant difference between women who underwent laparoscopy and those who underwent laparotomy in patient characteristics, proportion of women who underwent lymphadenectomy, complications, total cost, patients' recall of postoperative pain, and patients' satisfaction with management. Women who underwent laparoscopy had a significantly longer operative time, more pelvic lymph nodes removed, a smaller drop in postoperative hematocrit, less pain medication, and a shorter hospital stay (194.8 versus 137.7 min, P obese women with early stage endometrial cancer can be safely managed through laparoscopy with excellent surgical outcome, shorter hospitalization, and less postoperative pain than those managed through laparotomy.

    Specific diagnostic criteria for pediatric restless legs syndrome (RLS) were published in 2003 following a workshop at the National Institutes of Health. Due to substantial new research and revision of the adult RLS diagnostic criteria, a task force was chosen by the International Restless Legs Syndrome Study Group (IRLSSG) to consider updates to the pediatric diagnostic criteria. A committee of seven pediatric RLS experts developed a set of 15 consensus questions to review, conducted a comprehensive literature search, and extensively discussed potential revisions. The committee recommendations were approved by the IRLSSG executive committee and reviewed by the IRLSSG membership. The pediatric RLS diagnostic criteria were simplified and integrated with the newly revised adult RLS criteria. Specific recommendations were developed for pediatric application of the criteria, including consideration of typical words used by children to describe their symptoms. Pediatric aspects of differential diagnosis, comorbidity, and clinical significance were then defined. In addition, the research criteria for probable and possible pediatric RLS were updated and criteria for a related condition, periodic limb movement disorder (PLMD), were clarified. Revised diagnostic criteria for pediatric RLS have been developed, which are intended to improve clinical practice and promote further research. Copyright © 2013 The Authors.

    Full Text Available Background: Laparoendoscopic single-site (LESS splenectomy which is performed on small number of patients, has been introduced with better cosmetic outcome, less postoperative pain, greater patient satisfaction and faster recovery compared to standard laparoscopy. Materials and Methods : Thirty six patients were included in the study comparing standard laparoscopic splenectomy (LS, 17 patients transumbilical multiport splenectomy performed with conventional laparoscopic instruments (TUMP-LS, 19 patients. Two groups of patients were compared retrospectively by means of operation time, intra- and postoperative blood loss, perioperative complications, packed red cell and platelet requirements, lenght of hospitalization, pain scores and patient satisfaction. Results: There was no mortality in any of the groups, and no significant differences determined in operative time (P = 0,069, intraoperative blood loss (P = 0,641, patient satisfaction (P = 0,506, pain scores (P = 0,173 and the average length of hospital stay (P = 0,257. Umbilical incisions healed uneventfully and no hernia formation or wound infection was observed during follow-up period (2-34 months. There were no conversions to open surgery. Conclusions: Transumbilical multiport splenectomy performed with the conventional laparoscopic instruments is feasible and could be a logical alternative to classical laparoscopic splenectomy by combining the advantages of single access techniques and standard laparoscopy.

  1. Effect on Negative Laparoscopy Rate in Chronic Pelvic Pain Patients Using Patient Assisted Laparoscopy

    1997-01-01

    Objective: To determine the value of Patient Assisted Laparoscopy (PAL) in the diagnosis of pelvic pain. Methods: One hundred patients with pelvic pain were assessed by the procedure of Patient Assisted Laparoscopy to determine the cause of chronic pelvic pain. Results: Of the 100 patients with pelvic pain, 12 patients were not assessed due to technique failure, which included reaction to the carbon dioxide gas, inadequate visualization due to abdominal adhesions or failure to enter peritoneum. Of the remaining 88 patients, 61 had endometriosis; 16 had adhesions not associated with endometriosis; five had hernias; one had occult bowel cancer; one pseudo-stone from previous cholecystectomy; one had pain as a result of staples used at hysterectomy and one patient had chronic Crohn's disease. Two patients had no demonstrated interabdominal cause for their symptoms. Conclusion: In contrast to the well published rate of 35% negative laparoscopy in those patients with pelvic pain when examined under general anesthetic, Patient Assisted Laparoscopy decreased the negative laparoscopy rate to less than 3%. This methodology was also of benefit in giving the patient a better understanding of the cause of her pain and the need for therapy. PMID:9876695

    Hysterectomy is one of the most common surgical procedures for women of reproductive age. Laparoscopy was introduced in the 1990es and is today one of the recommended routes of surgery. A recent observational study showed that operative time for hysterectomy was significantly lower for 3-dimensional compared to conventional laparoscopy. Complication rates were similar for the two groups. No other observational studies or randomized clinical trials have compared 3-dimensional to conventional laparoscopy in patients undergoing total hysterectomy for benign disease. The objective of the study is to determine if 3D laparoscopy gives better quality of life, less postoperative pain, less per- and postoperative complications, shorter operative time, or a shorter stay in hospital and a faster return to work or normal life, compared to conventional laparoscopy for benign hysterectomy. The design is a randomised multicentre clinical trial. Participants will be 400 women referred for laparoscopic hysterectomy for benign indications. Patients will be randomized to 3-dimensional or conventional laparoscopic hysterectomy. Operative procedures will follow the same principles and the same standard whether the surgeon's vision is 3-dimensional or conventional laparoscopy. Primary outcomes will be the impact of surgery on quality of life, assessed by the SF 36 questionnaire, and postoperative pain, assessed by a Visual Analogue scale for pain measurement. With a standard deviation of 12 points on SF 36 questionnaire, a risk of type I error of 3.3% and a risk of type II error of 10% a sample size of 190 patients in each arm of the trial is needed. Secondarily, we will investigate operative time, time to return to work, length of hospital stay, and - and postoperative complications. This trial will be the first randomized clinical trial investigating the potential clinical benefits and harms of 3-dimensional compared to conventional laparoscopy. The results may provide more evidence

    Researchers have traditionally relied upon various presurgical biopsychosocial measures to predict weight loss success following bariatric surgery. The present study proposed a diagnostic grouping system to predict postsurgical outcome. It was hypothesized that psychosocial and Minnesota Multiphasic Personality Inventory (MMPI)/Millon Clinical Multiaxial Inventory (MCMI) psychometric variables could be used to identify gastric bypass surgery candidates requiring additional preoperative and postoperative services. Of 143 candidates for surgical treatment of morbid obesity, 120 women and 23 men underwent psychological evaluation prior to approval for gastric bypass. Each was placed into one of four diagnostic groups based upon results of personality measures and a preoperative semistructured interview. Results support the K scale of the MMPI-2 as a significant predictor of postsurgical outcome; MCMI scores on the schizoid, schizotypal, and compulsive scales appeared to be better overall predictors of outcome.

    We performed a search of PUBMED and MEDLINE for articles concerning surgical management of early stage endometrial cancer from 1950 to 2011. From the articles collected we extracted data such as estimated blood loss, operating room time, complications, conversion to laparotomy, and length of hospital stay. Forty-seven relevant sources were analyzed. The patients in the laparoscopy group had less blood loss, fewer complications, longer operating room times, and a shorter length of stay. Lymph node count was similar in both groups. Although obesity is not a contraindication to laparoscopy, it does lead to a higher conversion rate. Route of surgical treatment had no impact on recurrence or survival. Robotic surgery has significant advantages over laparotomy, but advantages over laparoscopy are not as distinct. Laparoscopic hysterectomy offers several advantages over laparotomy. These advantages relate to improvements in patient care with comparable clinical outcome. After careful analysis we believe laparoscopy should be the standard of care for surgical management of early stage endometrial cancer. Copyright © 2012 AAGL. Published by Elsevier Inc.

    The objective was to evaluate the indications and clinical evolution of patients treated with laparoscopy. Eight hundred eighty two women undergoing conventional laparoscopy for gynecological pathology, patients were not preselected, preoperative and postoperative data were registered retrospectively. Main indications to perform laparoscopy were dismenorrhea and infertility. Endometriosis and pelvic adhesions were the most frequent findings detected in the study subjects. Endoscopic treatment resulted in minimal complications and short postoperative stay. As conclusion classic laparoscopy is a safe and efficacious technique for treatment gynecological pathology.

    Full Text Available Abstract Background Single nucleotide polymorphisms (SNPs and genes that exhibit presence/absence variation have provided informative marker sets for bacterial and viral genotyping. Identification of marker sets optimised for these purposes has been based on maximal generalized discriminatory power as measured by Simpson's Index of Diversity, or on the ability to identify specific variants. Here we describe the Not-N algorithm, which is designed to identify small sets of genetic markers diagnostic for user-specified subsets of known genetic variants. The algorithm does not treat the user-specified subset and the remaining genetic variants equally. Rather Not-N analysis is designed to underpin assays that provide 0% false negatives, which is very important for e.g. diagnostic procedures for clinically significant subgroups within microbial species. Results The Not-N algorithm has been incorporated into the "Minimum SNPs" computer program and used to derive genetic markers diagnostic for multilocus sequence typing-defined clonal complexes, hepatitis C virus (HCV subtypes, and phylogenetic clades defined by comparative genome hybridization (CGH data for Campylobacter jejuni, Yersinia enterocolitica and Clostridium difficile. Conclusion Not-N analysis is effective for identifying small sets of genetic markers diagnostic for microbial sub-groups. The best results to date have been obtained with CGH data from several bacterial species, and HCV sequence data.

    The aim of the study was to evaluate the use of laparoscopy for the assessment of the reproductive tract and stage of gonadal development of the tench (Tinca tinca). Laparoscopy was carried out from February to March 2009, on 30 anesthetized tenchs, 15 males and 15 females, of approximately 250 g bodyweight and 30 cm length, using a 1.9-mm rigid cystoscope. Male and female gonads, attached to the swim bladder, were visualized. Testes were orange with a striped appearance. Mature ovaries were cluster-shaped and whitish. Histological samples were collected, from the reproductive organs of both the sexes, with a forceps and showed the presence of gametes at different stages of maturity. The application of this minimally invasive diagnostic imaging technique could clinically be used as a powerful tool to evaluate the gender and to establish the reproductive status of tench and other fish.

    When laparoscopy was first introduced, skills were primarily taught using the apprenticeship model. A limitation of this method when compared to open surgery, was that it requires more time to practise and more frequent learning opportunities in clinical practice. The unique set of skills required in laparoscopy highlighted the need for new training methods that reduce the need for supervision and do not put the patient at risk. Simulation training was developed to meet this need. The overall purpose of this thesis was to explore simulation-based laparoscopic training at home. The thesis consists of five papers: a review, a validation study, a study of methodology, a randomised controlled trial and a mixed-methods study. Our aims were to review the current knowledge on training off-site, to develop and explore validity for a training and assessment system, to investigate the effect of take-home training in a simulation-based laparoscopic training programme, and to explore the use of take-home training. The first paper in this thesis is a scoping review. The aim of the review was to explore the current knowledge on off-site laparoscopic skills training. We found that off-site training was feasible but that changes were required in order for it to become an effective method of training. Furthermore, the select-ed instructional design varied and training programmes were designed using a variety of educational theories. Based on our findings, we recommended that courses and training curricula should follow established education theories such as proficiency-based learning and deliberate practice. Principles of directed self-regulated learning could be used to improve off-site laparoscopic training programmes. In the second study, we set out to develop and explore validity evidence of the TABLT test. The TABLT test was developed for basic laparoscopic skills training in a cross-specialty curriculum. We found validity evidence to support the TABLT test as a summative test

    Laparoscopy is nowadays a well-established surgical method and plays a main role in an ever-increasing range of indications in gynaecology. High-quality studies of surgical techniques are necessary to improve the quality of patient care. The present study aims at evaluating postoperative pain after gynaecological laparoscopy depending on the intraoperative CO2 pressure. In a prospective, monocentric, randomized single-blind study at the Department of Gynaecology and Obstetrics at the Hannover Medical School, we include patients scheduled for different laparoscopic procedures. Randomization of the intraoperative CO2 pressure was carried out in six groups. Pain was assessed the day after surgery by the blinded nurse using a visual analogue scale. 550 patients were included in the period from May 2013 to January 2016. The analysis of the per protocol population PPP (n = 360) showed no statistically significant difference between the six intervention groups with regard to mean postoperative pain perception. In direct comparison between two groups, an intraoperative CO2 pressure of 15 mmHg was associated with a significant higher pain score than a pressure of 12 mmHg. The difference was 7.46 mm on a 10 cm VAS. The results of our study indicate that a CO2 pressure of 12 versus 15 mmHg can be advantageous. However, the clinical relevance remains unclear due to the low difference in pain. The additional benefit of an even lower pressure of 10 or 8 mmHg cannot be reliably assessed; we found signs of poor visibility conditions in these low pressure groups.

    To investigate the influence of obesity on short-term outcomes after laparoscopy-assisted radical gastrectomy. Clinical data of 214 patients with gastric cancer, who underwent laparoscopy-assisted radical gastrectomy between May 2009 and December 2012 were analyzed retrospectively. Patients were divided into two groups, consisting of obese and non-obese patients. In the obese group, the BMI was ≥ 25.0 kg/m² (n=66), and in the non-obese group was obese group than that in non-obese group [(271.5 ± 51.2) min vs. (252.1 ± 53.6) min, Pobese group was less than that in non-obese group (26.2 ± 10.3 vs. 30.3 ± 12.4, P0.05). There were no significant differences between the two groups with respect to postoperative complications rate (25.8% vs. 20.9%, P>0.05) and perioperative mortality (1.5% vs. 0.7%, P>0.05). However, minor surgery-related complication rate was higher in obese group(16.7% vs. 6.8%, Pgastric emptying. There was no difference in perioperative mortality between the two groups (1.5% vs. 0.7%, P>0.05). Although obesity prolongs the duration of laparoscopy-assisted radical gastrectomy, and increases the risk of minor surgery-related complications, it has no influence on the surgical safety.

    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.

    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.

    We present the case of a 64-year-old female with an incarcerated right femoral hernia, associated with a small bowel obstruction that was successfully treated with an open femoral hernia repair with plug. At the same time we performed a hernia sac laparoscopy to evaluate the viability of the previously reduced small bowel. The hernioscopy was performed with a 0° 5 mm scope with reliable evaluation of the peritoneal cavity. We confirm that hernioscopy is a safe and feasible procedure and provides useful information for the appropriate management of acute incarcerated femoral/inguinal hernias.

    Standard laparoscopy has undergone many recent advances with the advent of three-dimensional visual systems and robotic surgical systems. In evaluating the usefulness of these new systems, it is difficult to objectively measure their advantages in the operating room. Therefore, we designed a trial using three different laparoscopic modalities to evaluate the strengths and weaknesses of each modality. Twenty-seven subjects were entered into the study. Three different laparoscopic modalities were tested. These included standard laparoscopy with two-dimensional cameras, the 3Di Endosite visual system, and the daVinci Robotic Surgical System. A standard laparoscopic trainer was utilized and testing consisted of three different tasks: peg transfer, ring manipulation, and cannulation. Of the 27 subjects, 16 (60%) reported some degree of laparoscopic experience. The number of pegs transferred with standard laparoscopy and the Endosite 3Di system was significantly greater than with the robot. The number of errors committed during the peg transfer test and the amount of time required was significantly lower with the Endosite 3Di system compared to the robot. Subjects completed the ring manipulation task significantly faster with the robot, but the number of errors committed was no different among the three modalities. Subjects were able to complete the cannulation task with their dominant hand significantly faster with the robot compared to the Endosite 3Di system or standard laparoscopy, and committed fewer errors using the robot compared to standard laparoscopy. This study showed improved performance using three-dimensional optics on some tasks, but not a significant improvement in overall results. Three-dimensional vision does appear beneficial during performance of some complex tasks. The wrist-like action of the robot improved performance on some tasks, while the lack of tactile feedback likely was a source of errors on other tasks.

    Laparoscopy under total intravenous anesthesia (TIVA) with spontaneous respiration is a commonly encountered procedure in ambulatory gynecologic surgery. The purpose of this study was to evaluate the efficacy of TIVA using propofol and ketamine, compared with endotracheal inhalational general anesthesia (EIGA) for ambulatory gynecologic laparoscopy. Fifty-eight female patients, aged 17-48 years, were randomly allocated into two groups. Group 1 (TIVA) (n = 28) received propofol at the induction of anesthesia followed by propofol infusion for maintenance. Intravenous ketamine 0.5 mg/kg was administered before operation for anesthetic effect. Natural airway and spontaneous breathing were then maintained in patients. Group 2 (n = 30) received EIGA with isoflurane under controlled ventilation. We found that the two groups demonstrated similar trend characters of pH and PaCO2 during operation and in recovery room. The incidence of postoperative vomiting was higher in group 2 than in group 1 (30% vs. 7%; p sore throat was higher in group 2 than in group 1 (47% vs. 7%; p < 0.001). We conclude that TIVA with spontaneous respiration is suitable for ambulatory gynecologic laparoscopy.

    Herein, we report the results of study of Anopheles species in Primorsk and Khabarovsk regions of Russia. Three species of the Anopheles hyrcanus group: An. kleini, An. pullus, and An. lesteri were identified by molecular taxonomic diagnostics for the first time in Russia. Surprisingly, An. sinensis, which earlier was considered the only species of Anopheles in Russian Far East, was not observed. We analyzed nucleotide variation in the 610-bp fragment of the 5' end of the cytochrome c oxidase subunit I (COI) region. All species possessed a distinctive set of COI sequences. A maximum likelihood phylogenetic tree was constructed for members of the hyrcanus group. The examined Anopheles hyrcanus group members could be divided into two major subgroups: subgroup 1 (An. hyrcanus and An. pullus) and subgroup 2 (An. sinensis, An. kleini, and An. lesteri), which were found to be monophyletic.

    The diagnosis of chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) requires a careful clinical and neurophysiological evaluation, often completed by CSF analysis. In numerous cases, this diagnosis is straightforward and leads to rapid initiation of an immunomodulatory treatment. However, some patients are not diagnosed because of atypical clinical and/or neurophysiological features, and do not benefit from a potentially effective treatment. In this context, a working group was composed with the task of establishing recommendations on diagnostic strategies for CIDP in the main clinical situations where this diagnosis may be suspected. We have summarized these recommendations and tried to present them in the form of a decision-making algorithm.

    Minutes of the Hampstead Clinic's Diagnostic Profile Research Group during a fifteen-month period (1964-1965) are reviewed and discussed. A wide range of topics were considered and discussed, with a special focus on the affective life, object relations, and ego function of atypical children in comparison to the early ego functions and differentiation of normal and neurotic children. These lively clinical and theoretical discussions and their implications for therapeutic work with a wide range of children, demonstrate the multifaceted leadership and contributions of Anna Freud as teacher, clinician, and thinker, and of the Hampstead Clinic as a major center for psychoanalytic studies.

    The objective of this paper is the comparison between two different technologies used for the removal of a uterine myoma, a frequent benign tumor: the standard technology currently used, laparoscopy, and an innovative one, colpoceliotomy. It was considered relevant to evaluate the real and the potential effects of the two technologies implementation and, in addition, the consequences that the introduction or exclusion of the innovative technology would have for both the National Health System (NHS) and the entire community. The comparison between these two different technologies, the standard and the innovative one, was conducted using a Health Technology Assessment (HTA). In particular, in order to analyse their differences, a multi-dimensional approach was considered: effectiveness, costs and budget impact analysis data were collected, applying different instruments, such as the Activity Based Costing methodology (ABC), the Cost-Effectiveness Analysis (CEA) and the Budget Impact Analysis (BIA). Organisational, equity and social impact were also evaluated. The results showed that the introduction of colpoceliotomy would provide significant economic savings to the Regional and National Health Service; in particular, a saving of € 453.27 for each surgical procedure. The introduction of the innovative technology, colpoceliotomy, could be considered a valuable tool; one offering many advantages related to less invasiveness and a shorter surgical procedure than the standard technology currently used (laparoscopy).

    Full Text Available Problem statement: Hysteroscopy is a procedure in which the endometrial cavity is observable and subject of manipulation via transcervical route. Hysteroscopy is a minimally invasive process in diagnosis and treatment of many intrauterine and endocervical conditions. Polypectomy, myomectomy and endometrial ablation could be easily manageable by this procedure. According to safety and high efficiency of hysteroscopy, this method is changing to a widespread procedure in dealing with many gynecologic and obstetrical conditions. This study aimed at evaluating the diagnostic and therapeutical efficiency of hysteroscopy in managing of common conditions including abnormal uterine bleeding and abortion. Approach: In a descriptive cross-sectional setting, 243 women underwent hysteroscopy were evaluated in two groups: with uterine bleeding 236 cases and with recurrent abortions 7 cases. This study was conducted in Tabriz Alzahra Educational Center during a 15-month period. The main causes of the complaints were determined in each group. Six months after treatment, the overall success rate was recorded. Results: Hysteroscopy was the sole diagnostic procedure in 16.5 and 14.3% of the patients in groups with abnormal uterine bleeding and abortion, respectively. In the group with abnormal uterine bleeding, curettage, myomectomy, polypectomy, hysterectomy, laparoscopy and laparotomy were the main diagnostic-therapeutical approaches along with the hysteroscopy in descending order. In the group with recurrent abortion, laparoscopy, curettage and myomectomy were the main diagnostic-therapeutical approaches along with the hysteroscopy in descending. There was not any major complication. The diagnostic-therapeutical measures accompanying with the laparoscopy were successful in 73.5% of the bleeding group in follow-up period. Conclusion: Based on our results, hysteroscopy is a safe, accurate and highly-efficient procedure in managing women with abnormal uterine

    Limiting surgical morbidity while maintaining staging adequacy is a primary concern in obese patients with uterine malignancy. The goal of this study was to compare the surgical adequacy and postoperative morbidity of three surgical approaches to staging the disease of obese women with uterine cancer. The records of all patients with a body mass index (BMI) of >or=35 undergoing primary surgery for uterine corpus cancer at our institution from January 1993 to May 2006 were reviewed. Patients were assigned to three groups on the basis of planned surgical approach-standard laparotomy, laparoscopy, or laparotomy with panniculectomy. Standard statistical tests appropriate to group size were used to compare the three groups. In all, 206 patients with a BMI of >or=35 were grouped as follows: laparotomy, 154 patients; laparoscopy, 25 patients; and laparotomy with panniculectomy, 27 patients. Median BMI was 41 (range, 35-84). Regional lymph nodes were removed in 45% of the laparotomy patients, 40% of the laparoscopy patients, and 70% of the panniculectomy patients (P = .04). Compared with laparotomy, both laparoscopy and panniculectomy yielded higher median pelvic and total lymph node counts (P = .001). Operative time was shortest after standard laparotomy, and blood loss was greatest after panniculectomy. The incidence of all incisional complications was lower for panniculectomy (11%) and laparoscopy (8%) compared with standard laparotomy (35%) (P = .002). On multivariate analysis, a significantly lower risk of total incisional complications was seen for patients undergoing panniculectomy (risk ratio, .25; 95% confidence interval, .071-.88) and laparoscopy (risk ratio, .19; 95% confidence interval, .04-.94). Both laparoscopic staging and panniculectomy in a standardized fashion were associated with an improved lymph node count and a lower rate of incisional complications than laparotomy alone. Although definitive conclusions are limited by low patient numbers, the

    Objective:To observe the effect of different CO2 pneumoperitoneum pressure on the stress state in patients underwent gynecological laparoscopy.Methods:A total of 90 patients who were admitted in our hospital from February, 2015 to October, 2015 for gynecological laparoscopy were included in the study and divided into groups A, B, and C according to different CO2 pneumoperitoneum pressure. The changes of HR, BP, and PetCO2 during the operation process in the three groups were recorded. The changes of stress indicators before operation (T0), 30 min during operation (T1), and 12 h after operation (T2) were compared. Results: The difference of HR, BP, and PetCO2 levels before operation among the three groups was not statistically significant (P>0.05). HR, BP, and PetCO2 levels 30 min after pneumoperitoneum were significantly elevated when compared with before operation (P0.05). PetCO2 level 30 min after pneumoperitoneum in group B was significantly higher than that in group A (P0.05).Conclusions:Low pneumoperitoneum pressure has a small effect on the stress state in patients underwent gynecological laparoscopy, will not affect the surgical operation, and can obtain a preferable muscular relaxation and vision field; therefore, it can be selected in preference.

    AIM: To evaluate the potential of laparoscopy in the diagnosis of cirrhosis and outcome of interferon treatment in HCV-infected patients.METHODS: In this retrospective study, diagnostic laparoscopy with laparoscopic liver biopsy was performed in 72 consecutive patients with chronic HCV infection. The presence or absence of cirrhosis was analyzed macroscopically by laparoscopy and microscopically by liver biopsy specimens. Clinical and laboratory data and outcome of interferon-alfa treatment were compared between cirrhotic and noncirrhotic patients.RESULTS: Laparoscopically, cirrhosis was seen in 29.2%(21/72) and non-cirrhosis in 70.8% (51/72) of patients.Cirrhotic patients were significantly older with a significant longer duration of HCV infection than noncirrhotic patients.Laboratory parameters (AST, y-GT, y-globulin fraction) were measured significantly higher as well as significantly lower (prothrombin index, platelet count) in cirrhotic patients than in non-cirrhotic patients. Histologically, cirrhosis was confirmed in 11.1% (8/72) and non cirrhosis in 88.9% (64/72). Patients with macroscopically confirmed cirrhosis (n=21) showed histologically cirrhosis in 38.1% (8/21) and histologically noncirrhosis in 61.9% (13/21). In contrast, patients with macroscopically non-cirrhosis (n=51) showed histologically non cirrhosis in all cases (51/51). Thirty-nine of 72 patients were treated with interferon-alfa, resulting in 35.9% (14/39)patients with sustained response and 64.1% (25/39) with non response. Non-responders showed significantly more macroscopically cirrhosis than sustained responders. In contrast, there were no significant histological differences between non-responders and sustained responders.CONCLUSION: Diagnostic laparoscopy is more accurate than liver biopsy in recognizing cirrhosis in patients with chronic HCV infection. Liver biopsy is the best way to assess inflammatory grade and fibrotic stage. The invasive marker for staging, prognosis and

    Arm, neck and/or shoulder complaints are common in western societies. In the Netherlands, general practice guidelines are issued on shoulder pain and epicondylitis only. Little is known about actual management of the total range of diagnoses. The objectives of the study are: to determine management in patients consulting the GP with a new episode of non-traumatic arm neck and shoulder complaints up to 6 months after the first consultation. To evaluate differences in management between patients with specific diagnoses versus non-specific diagnoses and between specific diagnostic groups. In a prospective cohort study in general practice. We recruited 682 eligible patients. Data on diagnosis, management, patient- and complaint-characteristics were collected. Co-occurrence of treatment options was presented in scaled rectangles. After 6 months, additional diagnostic tests had been performed in 18% of the patients, mainly radiographic examination (14%). Further, 49% had been referred for physiotherapy and 12% to the medical specialist. Patients with specific diagnoses were more frequently referred for specialist treatment, and patients with non-specific diagnoses for physiotherapy. Corticosteroid injections (17%) were mainly applied specific diagnoses (e.g. impingement syndrome, frozen shoulder, carpal tunnel and M. Quervain). Frequencies of prescribed medication (51%) did not differ between specific and non-specific diagnoses. In 19% of the patients no referral, prescribed analgesics or injection was applied. Braces (4%) were mainly prescribed in epicondylitis. Overall, management most frequently consisted of prescribed analgesics and referral for physiotherapy. Specific and non-specific diagnostic subgroups differed in the frequency corticosteroid injections were applied, and referrals to physiotherapy and to a medical specialist.

    The purpose of this study was to assess the performances of the group A streptococcus (GAS) rapid antigen diagnostic tests (RADTs) in extra-pharyngeal infections. Between October 2009 and June 2014, 368 patients (median age: 48 months) were enrolled. The pathologies involved were : 160 perineal infections (44 %), 69 blistering distal dactylitis (19 %), 55 cervical lymphadenitis (15 %), 31 crusty or bleeding rhinitis (8 %), and 53 other diseases (14 %). The sensitivity of GAS-RADT used was 96 % (95 % CI: 92-99 %), the specificity 81 % (95 % CI: 75- 86 %), the negative predictive value 97 % (CI 95 %: 93-99 %), and the positive predictive value 79 % (95 % CI: 73-85 %). Finally, positive and negative likelihood ratio were 5 (95 % CI: 4-7) and 0.05 (95 % CI: 0.02-0.11) respectively. The GAS-RADTs developed for pharyngitis have comparable performances in these settings and therefore can be used.

    Laparoscopy-assisted surgery for either rectal or gastric cancer has been increasingly performed. However, simultaneous laparoscopy-assisted resection for synchronous rectal and gastric cancer is rarely reported in the literature. In our study, 3 cases of patients who received simultaneous laparoscopy-assisted resection for synchronous rectal and gastric cancer were recorded. The results showed that all 3 patients recovered well, with only 253 minutes of mean operation time, 57 mL of intraoperative blood loss, 5 cm of assisted operation incision, 4 days to resume oral intake, 12 days' postoperative hospital stay, and no complication or mortality. No recurrence or metastasis was found within the follow-up period of 22 months. When performed by surgeons with plentiful experience in laparoscopic technology, simultaneous laparoscopy-assisted resection for synchronous rectal and gastric cancer is safe and feasible, with the benefits of minimal trauma, fast recovery, and better cosmetic results, compared with open surgery.

    Three hundred and forty patients suffering from primary and secondary infertility were investigated by laparoscopy with the following results. 1. The substantial and most common causes of infertility were related to chronic pelvic inflammatory disease and pelvic endometriosis. 2. Comparison of the result of chromopertubation under direct vision during laparoscopy with the preoperative results with hysterosalpingography and phenolphthaline tubal instillation test showed significant difference (P<0.01). In the tubal patent group the compatibility of the results was 90.2% and 79% respectively whereas in the obstructed tubal group the discrepancy between the results was 50.5% and 59% respectively. 3. With the aid of laparoscopic investigation, the underlying cause of infertility could be verified in 97.6% of the patients. In 53.2% of the cases 14 different kinds of operations were performed directly under the laparascope,while 12.9% of the cases required laparotomy. In 58.5% of the patients laparoscopy was performed in combination with hysteroscopy and 26 operations,consisting of uterine septum resection and intrauterine adhesiolysi8 were completed undder the monitoring of the laparoscope.

    State-of-the-art laparoscopes for minimally invasive abdominal surgery are encumbered by cabling for power, video, and light sources. Although these laparoscopes provide good image quality, they interfere with surgical instruments, occupy a trocar port, require an assistant in the operating room to control the scope, have a very limited field of view, and are expensive. MARVEL is a wireless Miniature Anchored Robotic Videoscope for Expedited Laparoscopy that addresses these limitations by providing an inexpensive in vivo wireless camera module (CM) that eliminates the surgical-tool bottleneck experienced by surgeons in current laparoscopic endoscopic single-site (LESS) procedures. The MARVEL system includes 1) multiple CMs that feature a wirelessly controlled pan/tilt camera platform, which enable a full hemisphere field of view inside the abdominal cavity, wirelessly adjustable focus, and a multiwavelength illumination control system; 2) a master control module that provides a near-zero latency video wireless communications link, independent wireless control for multiple MARVEL CMs, digital zoom; and 3) a wireless human-machine interface that gives the surgeon full control over CM functionality. The research reported in this paper is the first step in developing a suite of semiautonomous wirelessly controlled and networked robotic cyber-physical devices to enable a paradigm shift in minimally invasive surgery and other domains such as wireless body area networks.

  16. The history and future of operative laparoscopy.

    Rock, J A; Warshaw, J R

    1994-01-01

    Laparoscopic sterilization was first performed in the United States in 1941. During the 1950s and 1960s hospitals procured the relatively inexpensive basic laparoscopic instrumentation, and education for physicians learning the techniques was provided mostly by academic centers during residency training. Interest in expansion of laparoscopic procedures was slight until the mid-1980s when operative laparoscopic management of ectopic pregnancies began to spread from academic centers to the private sector. Major technologic developments in instrumentation greatly simplified the endoscopic procedures and provided the first impetus for an explosive growth of operative laparoscopic applications in surgery. The great financial resources of private hospitals enabled them to adapt and retool quickly for operative endoscopy. Lacking these resources, academic institutions lagged behind; thus a growing divergence began between academic and private institutions in their influence on the development, use, and acceptance of the new technology. The development of expensive disposable instruments, with costs passed on to patients by private hospitals, further priced academic institutions out of the market. Two concerns today are paramount regarding operative laparoscopy: (1) The majority of laparoscopic techniques and procedures being performed by surgeons in this country have not been taught in the controlled setting of a residency or fellowship training program; (2) the legitimacy of the procedures themselves is questionable because of lack of sufficient data in the literature to support them. Academic institutions, working in tandem with the private sector, must assume the responsibility for answering these concerns.

    The All Patient Refined-Diagnostic Related Group (APR-DRG) is a modification of the traditional DRG that adds four classes of illness severity and four classes of mortality risk. The APR-DRG is a more accurate assessment of the complexity of care. When individuals with advanced illness are admitted to an acute inpatient palliative medicine unit, there may be a perception that they receive less intense acute care. Most of these patients, however, are multisymptomatic, have several comorbidities, and are older. For all patients admitted to the unit, a guide was followed by staff physicians to document clinical information that included the site(s) of malignancy, site(s) of metastases, disease complications, disease-related symptoms, and comorbidities. We then prospectively compared DRGs, APR-DRGs, and case mix index (CMI) from January 1-June 30, 2003, and February 1-July 31,2004, before and after the use of the guide. The overall mean severity of illness (ASOI) increased by 25% (P < 0.05). The mean CMI increased by 12% (P < 0.05). The average length of stay over the same period increased slightly from 8.97 to 9.56 days. Systematic documentation of clinical findings using a specific tool for patients admitted to an acute inpatient palliative medicine unit based on APR-DRG classifications captured a higher severity of illness and may better reflect resource utilization.

    The aim of this study was to observe the prevalence of diagnostic groups of temporomandibular disorders (TMD) in patients who were referred or sought treatment for TMD and/or orofacial pain in a private clinic. The clinical records of 357 patients were evaluated and selected based on inclusion/exclusion criteria; the mean age was 32 years. A clinical examination was performed and the diagnosis was based on the American Academy of Orofacial Pain criteria. Results showed that 86.8% of patients were women and 93.3% of the patients presented more than one diagnosis. The most frequent chief complaint (n = 216, chi2 = 30.68, p = 0.001) and total diagnosis realized (n = 748, chi2 = 14.14, p = 0.001) were muscle related. We concluded that women seek treatment for dysfunction/disorders of orofacial structures more than men do; patients seeking specialized treatment have more than one diagnosis and muscle dysfunction is more prevalent than intra-articular disorders.

    Full Text Available The bactericidal activity of serum caused by complement system is an important defence mechanism protecting the host organism against infection. The capacity to resist bactericidal activity of normal human serum contributes to the virulence of many gram-negative pathogens. Serum resistance in bacteria has been attributed to their surface components, but exact mechanism of resistance which most likely involves multiple factors is not well understood. In this study, the capacity of Escherichia coli to resist the bactericidal action of serum was examined in 85 clinical isolates obtained from patients with acute pyelonephritis (n=23, acute cystitis (n=22, chronic pyelonephritis (n=22 and asymptomatic bacteriuria (n=18. Serum sensitivity was also examined in relation to the serogroup specificity and expression of the different adhesins of the strains.Bacterial susceptibility to serum killing was measured by assessing regrowth after incubation in serum according to Schiller and Hatch method. The adhesins of E. coli were determined by hemagglutination and inhibition of hemagglutiation, and serotyping was performed on glass slides and confirmed using a mechanized microtechnique.The significant correlation between serum resistance of uropathogenic strains of E. coli and expression of P-fimbriae and O6 serogroup was observed.Theincidence of serum-resistant E. coli strains was significantly higher in strains isolated from urine of patients with acute pyelonephritis, as compared to strains isolated in other diagnostic groups, which is in accordance with higher virulence and invasive potential of these strains.

    The aim of the present study was to demonstrate the advantages of laparoscopy versus laparotomy for treatment of extremely obese women with early-stage endometrial cancer. Seventy-five extremely obese patients with Body Mass Index >35 kg/m(2) and clinical stage I endometrial cancer underwent hysterectomy and bilateral salpingo-oophorectomy, and in all cases we performed systematic pelvic lymphadenectomy by laparoscopy (mean BMI of 38±7.3 kg/m(2)) or laparotomy (mean BMI of 39±8.1 kg/m(2)). In two (4.4%) patients of the laparoscopy group we observed a port site haematoma that was resolved without a second surgery. In three patients of the laparotomy-group, we observed dehiscence of the abdominal suture with surgical site infection that was re-sutured. Laparoscopy can be considered a safe and effective therapeutic procedure for managing early-stage endometrial cancer in extremely obese women with a lower complication rate, lower surgical site infection and postoperative hospitalization.

    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.

    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.

    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

    In March 2009, a 25-yr-old captive female African elephant (Loxodonta africana) underwent an exploratory laparoscopy after several weeks of diarrhea, submandibular and ventral edema, and swelling on medial and lateral aspects of all feet. Although there have been recent advances in laparoscopic vasectomies in free-ranging African elephants in South Africa utilizing specially designed rigid laparoscopes and insufflation devices, this was the first attempt at using these same techniques for an exploratory purpose. The elephant was sedated in a static restraint chute and remained standing for the duration of the procedure. Laparoscopy provided visibility of the dorsal abdomen, enabled collection of reproductive tract biopsies and peritoneal fluid samples, and allowed for instillation of antibiotics and crystalloid fluids directly into the abdominal cavity. Abdominal exploration, collection of tissue samples, and local therapy is possible via standing laparoscopy in megavertebrates.

    Objective:To observe the effect of preemptive analgesia with parecoxib sodium on the postoperative pain and complications for patients undergoing gynecological laparoscopy. Methods:A total of 100 patients with ASA I-II grade who were admitted in our hospital from January, 2013 to February, 2014 and were undergoing gynecological laparoscopy were included in the study and randomized into the observation group and the control group. The patients in the observation group were given parecoxib sodium injection (40 mg) 30 min before operation and fentanyl citrate injection (1.0μg/kg) 30 min before the end of the surgery, while the patients in the control group were givens injections of parecoxib sodium injection (40 mg) and fentanyl citrate injection (1.0μg/kg) 30 min before the end of the surgery. The analgesia and sedation effects 4, 8, 12 h after the operation in the two groups were observed, and the postoperative additional fentanyl dosage and the adverse reactions were recorded.Results: The postoperative VAS score in each timing point and the total dosage of fentanyl in the observation group were significantly lower than those in the control group (P0.05).Conclusions: The preemptive analgesia with parecoxib sodium can reduce the dosage of postoperative analgesia medications with an accurate analgesic effect; therefore, it deserves to be widely recommended in the clinic.

    We examine differential validity of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) diagnoses assessed by the fully-structured Composite International Diagnostic Interview Version 3.0 (CIDI) among Latino, non-Latino Black, and non-Latino White adolescents in comparison to gold standard diagnoses derived from the Schedule for Affective Disorders and Schizophrenia for School-age Children (K-SADS). Results are based on the National Comorbidity Survey Replication Adolescent Supplement, a national US survey of adolescent mental health. Clinicians re-interviewed 347 adolescent/parent dyads with the K-SADS. Sensitivity and/or specificity of CIDI diagnoses varied significantly by ethnicity/race for four of ten disorders. Modifications to algorithms sometimes reduced bias in prevalence estimates, but at the cost of reducing individual-level concordance. These findings document the importance of assessing fully-structured diagnostic instruments for differential accuracy in ethnic/racial subgroups.

    BACKGROUND: Laparoscopic surgery is widely used, and results in accelerated patient recovery time and hospital stay were compared with laparotomy. However, laparoscopic surgery is more challenging compared with open surgery, in part because surgeons must operate in a three-dimensional (3D) space...... through a two-dimensional (2D) projection on a monitor, which results in loss of depth perception. To counter this problem, 3D imaging for laparoscopy was developed. A systematic review of the literature was performed to assess the effect of 3D laparoscopy. METHODS: A systematic search of the literature...

    To develop content for a basic laparoscopic curriculum in gynaecology. Prospective cross-sectional observational study. Modified Delphi method with three iterations undertaken by an invited group of national experts across the United Kingdom (UK). Two anonymous online surveys and a final physical group meeting were undertaken. Junior trainees in gynaecology undertook a parallel iteration of the Delphi process for external validation. Population included: expert panel - certified specialists in minimal-access gynaecological surgery, RCOG national senior trainee representatives, and medical educationalists, junior trainees group - regional trainees in gynaecology in first and second year of speciality training. Experts (n=37) reached fair to almost complete significant agreement (κ=0.100-0.8159; pcurriculum. Findings indicated that 39 categories should be included in the curriculum. Port placement, laparoscopic equipment and patient selection were ranked the most important theoretical categories. Hand-eye co-ordination, camera navigation and entry techniques were deemed the most valuable skills. Diagnostic laparoscopy, laparoscopic sterilisation, and laparoscopic salpingectomy were the operations agreed to be most important for inclusion. Simulation training was agreed as the method of skill development. The expert panel favoured box trainers, whereas the junior trainee group preferred virtual reality simulators. A basic simulation laparoscopic hand-eye co-ordination test was proposed as a final assessment of competence in the curriculum. Consensus was achieved on the content of a basic laparoscopic curriculum in gynaecology, in a cost- and time-effective, scientific process. The Delphi method provided a simple, structured consumer approach to curriculum development that combined views of trainers and trainees that could be used to develop curricula in other areas of post-graduate education.

    To compare the results of total laparoscopic hysterectomy and total abdominal hysterectomy in morbidly obese women with early stage endometrial cancer. This prospective study was conducted on 140 morbidly obese women with body mass indices ≥35 kg/m(2) and presenting with clinical stage 1 endometrial cancer. The patients underwent total laparoscopic hysterectomy (n=70) or total abdominal hysterectomy (n=70), bilateral salpingo-oophorectomy, pelvic lymphadenectomy, and peritoneal washing. Age, parity, menopausal status, weight, height, medical problems, history of previous laparotomy, surgical procedure, operative time, estimated amount of blood loss, preoperative hematocrit, postoperative hematocrit, operative complications, conversion to laparotomy, need for intraoperative or postoperative blood transfusion, intraoperative and postoperative complications, secondary surgery, tumor stage, grade, histology, number of recovered lymph nodes, and visual pain scores of the patients were recorded. Postoperative complications were significantly higher in the laparotomy group. Hospital stay in the laparoscopy group was significantly lower than that in the laparotomy group. The visual pain scores were significantly higher in the laparotomy group on the first, second, and third postoperative days and on the day of discharge from the hospital. Resuming activity took a significantly longer time in the laparotomy group (34.70 days) than in the laparoscopic group (17.89 days). With the availability of skilled endoscopic surgeons, most obese women with early stage endometrial cancer can be safely managed by performing laparoscopy with an excellent surgical outcome, shorter hospitalization, less postoperative pain, and faster resumption of full activity.

Age, parity, menopausal status, weight, height, medical problems, history of previous laparotomy, surgical procedure, operative time, estimated amount of blood loss, preoperative hematocrit, postoperative hematocrit, operative complications, conversion to laparotomy, need for intraoperative or postoperative blood transfusion, intraoperative and postoperative complications, secondary surgery, tumor stage, grade, histology, number of recovered lymph nodes, and visual pain scores of the patients were recorded. Results Postoperative complications were significantly higher in the laparotomy group. Hospital stay in the laparoscopy group was significantly lower than that in the laparotomy group. The visual pain scores were significantly higher in the laparotomy group on the first, second, and third postoperative days and on the day of discharge from the hospital. Resuming activity took a significantly longer time in the laparotomy group (34.70 days) than in the laparoscopic group (17.89 days). Conclusion With the availability of skilled endoscopic surgeons, most obese women with early stage endometrial cancer can be safely managed by performing laparoscopy with an excellent surgical outcome, shorter hospitalization, less postoperative pain, and faster resumption of full activity.

    Full Text Available Goats (n=12 undergoing laparoscopy assisted embryo transfer were randomly allotted to two groups (I and II and injected lignocaine hydrochloride (4mg/kg or ropivacaine hydrochloride (1mg/kg at the lumbosacral epidural space. The animals were held with raised hind quarters for first three minutes following injection. Immediately after induction of regional anaesthesia, they were restrained in dorsal recumbency in Trendelenburg position in a cradle. Laparoscopy was performed after creating pneumoperitoneum using filtered room air. The mean (± S.E induction time in animals of group I was significantly shorter (5.33 ± 0.61 min than those belonging to group II (12.66 ±1.99 min. Complete analgesia developed throughout the hind quarters and abdomen for 30 min and 60 min in group I and II animal’s respectively. Unlike animals of group I, group II goats continued to show moderate analgesia for 180 minutes. The motor activity returned after a lapse of 130.00 ± 12.64 min and 405.00 ± 46.31 min respectively. Occasional vocalization and struggling was noticed in two goats one from each group irrespective of the surgical manipulations during laparoscopy. The rectal temperature and respiration rates showed only non-significant increase, but the heart rate values were significantly higher (P < 0.5 up to 150 min in animals of both the groups when compared to their baseline values. From this study, it was concluded that both anaesthetic agents produced satisfactory regional anaesthesia in goats undergoing laparoscopy. However, considering the very long delay in regaining the hind limb motor activity, the use of ropivacaine may not be recommended for this purpose. Supplementation of sedative/tranquilizer with lumbosacral epidural anaesthesia needs evaluation.

    Robert's uterus is a unique malformation, described as a septate uterus with a non-communicating hemicavity, consisting of a blind uterine horn usually with unilateral hematometra, a contralateral unicornuate uterine cavity and a normally shaped external uterine fundus. The main symptom in affected young women is pelvic pain that becomes intensified near menses. We describe the case of a 22-year-old woman who was referred for diagnostic assessment and treatment of a congenital uterine anomaly. We used three-dimensional sonohysterography with volume-contrast imaging, HDLive rendering mode and automatic volume calculation (SonoHysteroAVC) for the diagnosis, surgical planning and postoperative evaluation. These imaging techniques provided a complete understanding of the internal and external uterine structures, enabling us to perform a minimally invasive hysteroscopic metroplasty, guided by transrectal ultrasound, and therefore avoiding the need for laparotomy/laparoscopy. The outcome of treatment was considered satisfactory; menstruation ceased to be painful and, after two hysteroscopic procedures, the communicating 0.3-cm(3) hemicavity was visualized as a 3.6-cm(3) normalized uterine cavity using the same imaging techniques. The findings of this case report raise questions about the embryological origin of Robert's uterus, the suitability of current classification systems, and the role of more invasive approaches (laparoscopy/laparotomy) and surgical procedures (horn resection/endometrectomy) that do not aim to improve uterine cavity shape and volume in women with this condition.

    Residency programs struggle with integrating simulation training into curricula, despite evidence that simulation leads to improved operating room performance and patient outcomes. Currently, there is no standardized laparoscopic training program available for gynecology residents. The purpose of this study was to develop and validate a comprehensive ex vivo training curriculum for gynecologic laparoscopy. In a prospective, single-blinded randomized controlled trial (Canadian Task Force Classification I) postgraduate year 1 and 2 gynecology residents were allocated randomly to receive either conventional residency training or an evidence-based laparoscopy curriculum. The 7-week curriculum consisted of cognitive didactic and interactive sessions, low-fidelity box trainer and high-fidelity virtual reality simulator technical skills, and high-fidelity team simulation. The primary outcome measure was the technical procedure score at laparoscopic salpingectomy with the use of the objective structured assessment of laparoscopic salpingectomy tool. Secondary outcome measures related to performance in multiple-choice questions and technical performance at box trainer and virtual reality simulator tasks. A sample size of 10 residents per group was planned (n = 20). Results are reported as medians (interquartile ranges), and data were compared between groups with the Mann-Whitney U, chi-square, and Fisher's exact tests (P ≤ .05). In July 2013, 27 residents were assigned randomly (14 curriculum, 13 conventional). Both groups were similar at baseline. Twenty-one residents (10 curriculum, 11 conventional) completed the surgical procedure-based assessment in the operating room (September to December 2013). Our primary outcome indicated that curriculum-trained residents displayed superior performance at laparoscopic salpingectomy (P = .043). Secondary outcomes demonstrated that curriculum-trained residents had higher performance scores on the cognitive multiple

    Full Text Available AbstractDetermining 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. 24 trainees (control group without prior experience received a three week laparoscopic skills training utilizing four basic and one advanced training task. 28 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 two month 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 assess the efficacy of the TINTARA uterine manipulator and the Cohen cannula for gynecologic laparoscopy. Sixty women scheduled for laparoscopy were randomized for use of TINTARA (n = 30) or Cohen (n = 30) as a uterine manipulator. The degree of anterior and lateral deviation of the uterus, operative time, surgical complications and ease of use were recorded and compared between the two groups. The mean ranges of anterior and lateral deviation of the uterus in TINTARA and Cohen groups were 61.17 +/- 19.37 vs. 49.33 +/- 22.58 degrees (p = 0.033) and 107.03 +/- 39.68 vs. 85.5 +/- 37.52 degrees (p = 0.035) respectively. The percentage of patients having dye leakage from the cervix in the Cohen group was greater than in the TINTARA group, but the difference was not statistically significant. Both instruments provided similar ease of use. Complications were not found in either group. TINTARA was found to have more advantages than the Cohen in moving the uterus in both anterior and lateral directions.

    Ventriculoperitoneal shunting(VPS) is a widely accepted technique for the treatment of hydrocephalus. The probability of shunt dysfunction is pretty high throughout life. Laparoscopy has become a valuable tool to perform VPS and treat abdominal complications. An electronic literature search was performed to reveal the published data relating laparoscopy and ventriculoperitoneal shunt in Medline, Embase, Scielo and Lilacs databases. The keywords employed were “laparoscopy” OR “laparoscopic surgery” AND “ventriculoperitoneal shunt” OR “shunt” AND “surgery” OR “implantation” OR “revision” OR “complication”. No high quality trials were developed comparing conventional laparotomic incision vs laparoscopic approach. Both approaches have evolved and currently there are less invasive options for laparotomy, like periumbilical small incisions; and for laparoscopy, like smaller and less incisions. Operating room time, blood loss and hospital stay may be potentially smaller in laparoscopic surgery and complications are probably the same as laparotomy. In revision surgery for abdominal complications after VPS,visualization of whole abdominal cavity is fundamental to address properly the problem and laparoscopic approach is valuable once it is safe, fast and much less invasive than laparotomy. Ventriculoperitoneal shunting is a widely accepted technique for the treatment of hydrocephalus. Laparoscopy assisted shunt surgery in selected cases might be a less invasive and more effective option for intrabdominal manipulation. The laparoscopic approach allows a better catheter positioning, lysis of fibrotic bundles and peritoneal inspection as well, without any additional complication.

    Incidence of obesity and related diseases are increasing in the world. Visceral surgeons are more often confronted with laparoscopic surgery in obese patients. Besides validated surgery procedures, such as cholecystectomy and gastroesophageal reflux surgery, bariatric procedures are increasingly performed. In obese patients, the thickness of adipose panicle makes open laparoscopy hazardous. In our department, we use systematically a technique of open laparoscopy in obese patients for supramesocolic surgery, which is safe, reproducible, and permits good closure of the abdominal wall. The surgical technique consists of opening the abdominal wall through the rectus abdominis. Helped by specific retractors called Descottes (Medtronic Laboratory), both fascias are charged by sutures separately. Incision in the fascias is made safely by pooling on sutures. Introduction of port-site is made under view control. At the end of laparoscopy, closure of both fascias is easily done. We present a technique of open laparoscopy in obese patients, systematically used, for supramesocolic surgery. This technique is safe, reproducible, and permits an efficient closure of the abdominal wall.

  8. Echinococcus multilocularis Detection in Live Eurasian Beavers (Castor fiber Using a Combination of Laparoscopy and Abdominal Ultrasound under Field Conditions.

    Directory of Open Access Journals (Sweden)

    Róisín Campbell-Palmer

    Full Text Available Echinococcus multilocularis is an important pathogenic zoonotic parasite of health concern, though absent in the United Kingdom. Eurasian beavers (Castor fiber may act as a rare intermediate host, and so unscreened wild caught individuals may pose a potential risk of introducing this parasite to disease-free countries through translocation programs. There is currently no single definitive ante-mortem diagnostic test in intermediate hosts. An effective non-lethal diagnostic, feasible under field condition would be helpful to minimise parasite establishment risk, where indiscriminate culling is to be avoided. This study screened live beavers (captive, n = 18 or wild-trapped in Scotland, n = 12 and beaver cadavers (wild Scotland, n = 4 or Bavaria, n = 11, for the presence of E. multilocularis. Ultrasonography in combination with minimally invasive surgical examination of the abdomen by laparoscopy was viable under field conditions for real-time evaluation in beavers. Laparoscopy alone does not allow the operator to visualize the parenchyma of organs such as the liver, or inside the lumen of the gastrointestinal tract, hence the advantage of its combination with abdominal ultrasonography. All live beavers and Scottish cadavers were largely unremarkable in their haematology and serum biochemistry with no values suspicious for liver pathology or potentially indicative of E. multilocularis infection. This correlated well with ultrasound, laparoscopy, and immunoblotting, which were unremarkable in these individuals. Two wild Bavarian individuals were suspected E. multilocularis positive at post-mortem, through the presence of hepatic cysts. Sensitivity and specificity of a combination of laparoscopy and abdominal ultrasonography in the detection of parasitic liver cyst lesions was 100% in the subset of cadavers (95%Confidence Intervals 34.24-100%, and 86.7-100% respectively. For abdominal ultrasonography alone sensitivity was only 50% (95%CI 9

    Background Laparoscopic surgery is a modern surgical technique in which operations are performed far from their location through small incisions elsewhere in the body. Objective This systematic review is aimed to overview single-incision laparoscopy surgery. Methods This systematic review was carried out by searching studies in PubMed, Medline, Web of Science, and IranMedex databases. The initial search strategy identified about 87 references. In this study, 54 studies were accepted for further screening and met all our inclusion criteria [in English, full text, therapeutic effects of single-incision laparoscopy surgery and dated mainly from the year 1990 to 2016]. The search terms were “single-incision,” “surgery,” and “laparoscopy.” Results Single-incision laparoscopy surgery is widely used for surgical operations in cholecystectomy, sleeve gastrectomy, cholecystoduodenostomy, hepatobiliary disease, colon cancer, obesity, appendectomy, liver surgery, rectosigmoid cancer, vaginal hysterectomy, vaginoplasty, colorectal lung metastases, pyloroplasty, endoscopic surgery, hernia repair, nephrectomy, rectal cancer, colectomy and uterus-preserving repair, bile duct exploration, ileo-ileal resection, lymphadenectomy, incarcerated inguinal hernia, anastomosis, congenital anomaly, colectomy for cancer. Conclusion Based on the findings, single-incision laparoscopy surgery is a scarless surgery with minimal access. Although it possesses lots of benefits, including less incisional pain and scars, cosmesis, and the ability to convert to standard multiport laparoscopic surgery, it has some disadvantages, for example, less freedom of movement, fewer number of ports that can be used, and the proximity of the instruments to each other during the operation.

    Three experiments tested the hypotheses that while forming stereotypes of social groups, people abstract the central tendency and variability of different attribute dimensions to determine which ones best differentiate the groups and that more differentiating dimensions are more likely to become stereotypical in the sense of becoming strongly associated with the groups in memory. Supporting these hypotheses. Experiment 1 found that, after viewing behaviors performed by members of 2 groups, Ss characterized the groups more in terms of attribute dimensions indicating larger differences between the central tendencies of the groups, and Experiment 2 showed that this effect did not occur when Ss formed impressions of only 1 group. Experiment 3 found that Ss also characterized groups more in terms of attribute dimensions indicating lower within-group variability.

    Full Text Available Abstract Background Gastric cancer is a common malignancy worldwide and a common cause of death from cancer. Despite recent advances in multimodality treatment and targeted therapy, complete resection remains the only treatment that can lead to cure. This study was devised to investigate the technical feasibility, safety and oncologic efficacy of laparoscopy-assisted gastrectomy for advanced gastric cancer without serosa invasion. Methods A retrospective matched cohort study was performed in south China comparing laparoscopy-assisted gastrectomy and open gastrectomy for advanced gastric cancer without serosa invasion. Eighty-three patients with advanced gastric cancer undergoing laparoscopy-assisted gastrectomy between January 2008 and December 2010 were enrolled. These patients were compared with 83 patients with advanced gastric cancer undergoing open gastrectomy during the same period. Results There was no significant difference in clinicopathologic characteristics between the two groups. Regarding perioperative characteristics, the operation time and time to ground activities did not differ between the two groups, whereas the blood loss, transfused patient number, time to first flatus, time to resumption of diet, and postoperative hospital stay were significantly less in laparoscopy-assisted gastrectomy than in open gastrectomy (P Conclusion Laparoscopy-assisted gastrectomy with D2 lymphadenectomy is a safe and feasible procedure for advanced gastric cancer without serosa invasion. To be accepted as a choice treatment for advanced gastric cancer, well-designed randomized controlled trials comparing short-term and long-term outcomes between laparoscopy-assisted gastrectomy and open gastrectomy in a larger number of patients are necessary.

    2013-01-01

    In the last decade, different statistical techniques have been introduced to improve assessment of malingering-related poor effort. In this context, we have recently shown preliminary evidence that a Bayesian latent group model may help to optimize classification accuracy using a simulation research design. In the present study, we conducted two analyses. Firstly, we evaluated how accurately this Bayesian approach can distinguish between participants answering in an honest way (honest response group) and participants feigning cognitive impairment (experimental malingering group). Secondly, we tested the accuracy of our model in the differentiation between patients who had real cognitive deficits (cognitively impaired group) and participants who belonged to the experimental malingering group. All Bayesian analyses were conducted using the raw scores of a visual recognition forced-choice task (2AFC), the Test of Memory Malingering (TOMM, Trial 2), and the Word Memory Test (WMT, primary effort subtests). The first analysis showed 100% accuracy for the Bayesian model in distinguishing participants of both groups with all effort measures. The second analysis showed outstanding overall accuracy of the Bayesian model when estimates were obtained from the 2AFC and the TOMM raw scores. Diagnostic accuracy of the Bayesian model diminished when using the WMT total raw scores. Despite, overall diagnostic accuracy can still be considered excellent. The most plausible explanation for this decrement is the low performance in verbal recognition and fluency tasks of some patients of the cognitively impaired group. Additionally, the Bayesian model provides individual estimates, p(zi |D), of examinees' effort levels. In conclusion, both high classification accuracy levels and Bayesian individual estimates of effort may be very useful for clinicians when assessing for effort in medico-legal settings.

    2013-01-01

    Full Text Available Objective. To evaluate the safety and efficacy of Keyless Abdominal Rope-Lifting Surgery (KARS, for tubal sterilization procedures in comparison with the conventional CO2 laparoscopy. Material and Methods. During a one-year period, 71 women underwent tubal ligation surgery. Conventional laparoscopy (N=38 and KARS (N=33 were used for tubal sterilization. In KARS, an abdominal access pathway through a single intra-abdominal incision was used to place transabdominal sutures that elevated the abdominal wall, and the operations were performed through the intraumbilical entry without the use of trocars. In CO2 laparoscopy, following the creation of the CO2 pneumoperitoneum a 10 mm trocar and two 5 mm trocars were introduced into the abdominal cavity. Tubal sterilizations were performed following the creation of the abdominal access pathways in both groups. The groups were compared with each other. Results. All operations could be performed by KARS without conversion to CO2 laparoscopy or laparotomy. The mean operative time of the two groups was not significantly different (P>0.05. Intra- and postoperative findings including complications, bleeding, and hospital stay time did not differ between groups (P>0.05. Conclusion. KARS for tubal sterilization seems safe and effective in terms of cosmesis, postoperative pain, and early hospital discharge.

  14. The diagnostic plot analysis of artesian aquifers with case studies in Table Mountain Group of South Africa

    2015-05-01

    Parameter estimates of artesian aquifers where piezometric head is above ground level are largely made through free-flowing and recovery tests. The straight-line method proposed by Jacob-Lohman is often used for interpretation of flow rate measured at flowing artesian boreholes. However, the approach fails to interpret the free-flowing test data from two artesian boreholes in the fractured-rock aquifer in Table Mountain Group (TMG) of South Africa. The diagnostic plot method using the reciprocal rate derivative is adapted to evaluate the artesian aquifer properties. The variation of the derivative helps not only identify flow regimes and discern the boundary conditions, but also facilitates conceptualization of the aquifer system and selection of an appropriate model for data interpretation later on. Test data from two free-flowing tests conducted in different sites in TMG are analysed using the diagnostic plot method. Based on the results, conceptual models and appropriate approaches are developed to evaluate the aquifer properties. The advantages and limitations of using the diagnostic plot method on free-flowing test data are discussed.

    Obese patients pose additional operative technical difficulties, and it is unclear if the outcomes of single-port colorectal surgery are equivalent to those of conventional laparoscopy in such patients. The aim of this study was to compare perioperative variables and short-term outcomes of single-port versus conventional laparoscopy in obese patients undergoing colorectal surgery. Obese patients (BMI ≥ 30 kg/m(2)) undergoing single-port laparoscopic colorectal resections between March 2009 and September 2012 were case matched 1:1 with obese counterparts undergoing conventional (multi-port) laparoscopic surgery based on diagnosis and operation type. Thirty-seven patients who underwent single-port surgery were matched with 37 conventional laparoscopic counterparts. Male gender predominated in the single-port group (26 vs 15, p = 0.02). The number of patients with a history of previous abdominal operations (17 vs 13, p = 0.48) and ASA score (3 vs 2, p = 0.6) were similar between the groups. No differences were observed with respect to conversion rate (2 vs 5, p = 0.43), operative time (146 vs 150 min, p = 0.48), estimated blood loss (159 vs 183 ml, p = 0.99), time to first flatus (3 vs 3 days, p = 0.91), time to first bowel movement (3 vs 4 days, p = 0.62), length of hospital stay (7 vs 6 days, p = 0.37), or reoperation (2 vs 1, p > 0.99), and readmission rates (2 vs 2, p > 0.99). There were no deaths. For obese patients undergoing colorectal resections, single-port laparoscopy appears to be as safe and effective as conventional laparoscopy.

    Although 96-100% of individuals with eating disorders (EDs) report insecure attachment, the specific mechanisms by which adult insecure attachment dimensions affect ED symptomatology remain to date largely unknown. This study examined maladaptive perfectionism as both a mediator and a moderator of the relationship between insecure attachment (anxiety and avoidance) and ED symptomatology in a clinical, treatment seeking, sample. Insecure anxious and avoidant attachment, maladaptive perfectionism, and ED symptomatology were assessed in 403 participants from three medium size specialized care centres for EDs in Italy. Structural equation modeling indicated that maladaptive perfectionism served as mediator between both insecure attachment patterns and ED symptomatology. It also interacted with insecure attachment to predict higher levels of ED symptoms - highlighting the importance of both insecure attachment patterns and maladaptive aspects of perfectionism as treatment targets. Multiple-group comparison analysis did not reveal differences across diagnostic groups (AN, BN, EDNOS) in mediating, main and interaction effects of perfectionism. These findings are consistent with recent discussions on the classification and treatment of EDs that have highlighted similarities between ED diagnostic groups and could be viewed through the lens of the Trans-theoretical Model of EDs. Implications for future research and intervention are discussed.

    Background There is currently no Europe-wide consensus on the appropriate preanalytical measures and workflow to optimise procedures for tissue-based molecular testing of non-small-cell lung cancer (NSCLC). To address this, a group of lung cancer experts (see list of authors) convened to discuss and propose standard operating procedures (SOPs) for NSCLC. Methods Based on earlier meetings and scientific expertise on lung cancer, a multidisciplinary group meeting was aligned. The aim was to inc...

    High definition stereoscopic (3D) vision has been introduced into the operation theatre. This review exposes the optical and physiological background as well as the state of the art of 3D in laparoscopy. The distinguishing marks of 3D laparoscopes and monitors are listed and characteristics of stereoscopy, such as comfort zones and ghosting are explained. Suggestions for the practical use in the clinical routine should help to extract the best benefit possible from the new technology.

    Four new cases of necrosis of the omentum secondary to torsion are reported. We review the associated signs and symptoms, which are usually those of an acute inflammatory condition in the right lower quadrant (RLQ), very similar to acute appendicitis. Because of acute abdominal pain in the RLQ, along with an uncertain diagnosis, laparoscopic surgery was performed in these cases. Laparoscopy demonstrated the existence of the omental infarction and allowed for complete treatment of the condition without the need for laparotomy.

    2004-01-01

    To study the effect of CO2 pneumoperitoneum and the special 30 degree head-down tilt positionon the venous hemodynamics in the lower extremity. Methods: Color doplex ultrasound was adopted to evaluate the diameterand blood flow velocity of the right femoral vein of 18 patients undergoing gynecologic laparoscopy under the same pressure ofpneumoperitoneum of 12 mmHg. The diameter of femoral vein and the flow velocity were measured; the blood flow volumewas calculated based on the equation of Q = vπr2 . Result: After establishment of pneumoperitoneum, the dilation of the fem-oral vein and the decrease in the velocity and volume can be observed (P < 0.05). And the 30 degree head-down positioncould increase the flow velocity and volume of the femoral vein and decrease the diameter of the vessel ( P < 0.05). At 30minutes of the 30 degree head-down tilt position, the blood flow ameliorated compared with that in prone position after theestablishment of pneumoperitoneum. After deflation of pneumoperitoneum, the femoral vein remained dilated( P < 0.05 ).Conclusion: During laparoscopy, CO2 pneumoperitoneum may result in the dilation of the vein in lower extremity and retar-dance of blood flow. The 30 degree Trendlenburg position can ameliorate the blood flow in the lower extremity. The deflationof the pneumoperitoneum cannot eliminate the effect of CO2 pneumoperitoneum on the lower extremity veins, which may pre-dispose deep venous thrombosis after laparoscopy.

    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.

    Umbilical laparoendoscopic single-site (LESS) surgery is an increasingly used modality for treating renal masses. We present a prospective comparison between LESS renal surgery and conventional laparoscopy. A comparative paired study was conducted that evaluated the surgical results and complications of patients with renal neoplasia treated with LESS surgery (n=49) or multiport laparoscopy (n=53). The LESS approach was performed with reusable material placed in the navel and double-rotation curved instruments. An additional 3.5-mm port was employed in 69.4% of the cases. We assessed demographic data, the type of technique (nephrectomy, partial nephrectomy and nephroureterectomy), surgical time, blood loss, haemoglobin, need for transfusion, number and severity of complications (Clavien-Dindo), hospital stay, histological data and prognosis. There were no differences in follow-up, age, sex, body mass index, preoperative haemoglobin levels or type of surgery. Conversion occurred in 2 cases (1 in each group). The surgical time was equivalent (P=.6). Intraoperative transfusion (P=.03) and blood loss (Pmasses, with time consumption and safety comparable to conventional laparoscopy. The LESS approach is advantageous in terms of blood loss and hospital stay. Copyright © 2016 AEU. Publicado por Elsevier España, S.L.U. All rights reserved.

    2011-01-01

    Full Text Available Background: This study was undertaken to compare the postoperative pain after cholecystectomy done by single-incision laparoscopic surgery (SILS versus conventional four-port laparoscopy [conventional laparoscopic surgery (CLS]. SILS is a feasible and a promising method for cholecystectomy. It is possible to do this procedure without the use of special equipments. While there are cosmetic advantages to SILS, it is not clear whether or not the pain is also reduced. Methods: Patients undergoing cholecystectomy for symptomatic gallstones were offered the choice of the two methods and the first 100 consecutive patients from each group were included in this observational study. Only conventional instruments were used to keep the cost of surgery comparable. Pain scores were checked 8 hours after the surgery using visual analogue score. Student′s t test was done to check the statistical significance. Results: We observed no significant difference in the pain score between the CLS and SILS (2.78 versus 2.62. The operative time (OT was significantly lower in the CLS group (28 versus 67 minutes. Comparing the OTs of the first 50 patients undergoing SILS with the second 50 patients showed a significantly lower OT (79 versus 54 minutes. We also compared the pain score between these three groups. The second half of SILS group had a significantly lower pain score compared to the first half (2.58 versus 2.84. This group also had a lower pain score compared to conventional laparoscopy group but the difference was not statistically significant (2.58 versus 2.78. Conclusion: Although there was no significant difference in the overall postoperative pain as OT decreases with surgeon′s experience in single-incision laparoscopic cholecystectomy, postoperative pain at 8 hours appears to favour this method over conventional laparoscopic cholecystectomy.

  4. Disability transitions after 30 months in three community-dwelling diagnostic groups in Spain.

    Directory of Open Access Journals (Sweden)

    Jesús de Pedro-Cuesta

    Full Text Available BACKGROUND: Little is known about changes in disability over time among community-dwelling patients. Accordingly, this study sought to assess medium-term disability transitions. PATIENTS AND METHODS: 300 chronic obstructive pulmonary disease (COPD, chronic heart failure and stroke patients living at home in Madrid were selected from general practitioner lists. In 2009, disability was assessed after a mean of 30 months using the World Health Organisation (WHO Disability Assessment Schedule 2.0 (WHODAS 2.0. Follow-up was completed using death registries. Losses to follow-up were due to: death, 56; institutionalisation, 9; non-location, 18; and non-participation, 17. Changes in WHODAS 2.0 scores and life status were described and analysed using Cox and multinomial regression. Disability at end of follow-up was imputed for 56 deceased and 44 surviving patients. RESULTS: Mean disability scores for 200 surviving patients at end of follow-up were similar to baseline scores for the whole group, higher than their own baseline scores, and rose by 16.3% when imputed values were added. The strongest Cox predictors of death were: age over 84 years, adjusted hazard ratios with 95%CI 8.18 (3.06-21.85; severe/complete vs. no/mild disability, 5.18 (0.68-39.48; and stroke compared to COPD, 1.40 (0.67-2.91. Non-participants and institutionalised patients had higher proportions with severe/complete baseline disability. A one-point change in baseline WHODAS 2.0 score predicted independent increases in risk of 12% (8%-15% for severe/complete disability or death. CONCLUSIONS: A considerably high proportion of community-dwelling patients diagnosed with COPD, CHF and stroke undergo medium-term changes in disability or vital status. The main features of the emerging pattern for this group appear to be as follows: approximately two-thirds of patients continue living at home with moderately reduced functional status; 1/3 die or worsen to severe/complete disability; and 1

    In recent years the costs of hospital care in developed countries absorbed a high proportion of total health resources. In Greece, after the establishment of the National Health System (NHS), funding for hospitals comes mainly from the state budget, and social insurance, therefore auditing of hospital cost is imperative to ensure their viability, especially at this time when the country is tested by economic crisis. Overtime many factors for the increase of hospital cost have been mentioned, such as the rapid development of medical technology, the low level of organization of the hospital system and the low productivity of human resources. The problem of rising health expenditure over the past decades is a worldwide phenomenon and it has brought about many changes in traditional retrospective methods for financing in the hospital sector, with prospective financial forms that combine patient composition and needs, and the productive activity of hospital need to the rationalization and contain expenditures. The system of Diagnosis Related Groups was a revolutionary success over the past decades and has now achieved worldwide recognition.

    Full Text Available Primary peritonitis remains a rare disease in otherwise healthy children, with group A Streptococcus (GAS being a particularly unusual cause. A case involving a 14-year-old girl, who presented with an ‘acute abdomen’ and was taken to the operating room for urgent laparoscopy, is reported. Abdominal and pelvic structures were only minimally inflamed, as was the appendix. Peritoneal fluid and blood cultures both grew pure cultures of GAS. The patient’s course was complicated by streptococcal toxic shock syndrome. She fortunately made a full recovery. The present report highlights the diagnostic and treatment dilemmas associated with GAS primary peritonitis.

    Objectives Several ABILHAND Rasch-built manual ability scales were previously developed for chronic stroke (CS), cerebral palsy (CP), rheumatoid arthritis (RA), systemic sclerosis (SSc) and neuromuscular disorders (NMD). The present study aimed to explore the applicability of a generic manual ability scale unbiased by diagnosis and to study the nature of manual ability across diagnoses. Design Cross-sectional study. Setting Outpatient clinic homes (CS, CP, RA), specialised centres (CP), reference centres (CP, NMD) and university hospitals (SSc). Participants 762 patients from six diagnostic groups: 103 CS adults, 113 CP children, 112 RA adults, 156 SSc adults, 124 NMD children and 124 NMD adults. Primary and secondary outcome measures Manual ability as measured by the ABILHAND disease-specific questionnaires, diagnosis and nature (ie, uni-manual or bi-manual involvement and proximal or distal joints involvement) of the ABILHAND manual activities. Results The difficulties of most manual activities were diagnosis dependent. A principal component analysis highlighted that 57% of the variance in the item difficulty between diagnoses was explained by the symmetric or asymmetric nature of the disorders. A generic scale was constructed, from a metric point of view, with 11 items sharing a common difficulty among diagnoses and 41 items displaying a category-specific location (asymmetric: CS, CP; and symmetric: RA, SSc, NMD). This generic scale showed that CP and NMD children had significantly less manual ability than RA patients, who had significantly less manual ability than CS, SSc and NMD adults. However, the generic scale was less discriminative and responsive to small deficits than disease-specific instruments. Conclusions Our finding that most of the manual item difficulties were disease-dependent emphasises the danger of using generic scales without prior investigation of item invariance across diagnostic groups. Nevertheless, a generic manual ability scale could be

    Conclusion: The high prevalence of pelvic pathology found during laparoscopy confirms its role in the investigation and management of infertile women. While not all infertile women will need IVF, they will still benefit from laparoscopy either to assist natural conception, to direct them to IVF-ET, or to enhance IVF results.

  10. Vascular injuries during gynecological laparoscopy: the vascular surgeon's advice

    Marcello Barbosa Barros

    Full Text Available CONTEXT: Iatrogenic vascular problems due to laparoscopy are a well recognized problem and lead to significant repercussions. In this context, a ten-year review of cases topic is presented, based on experience gained while heading two important vascular surgery services. CASES: Five patients with vascular injuries during elective laparoscopy are described. These patients presented with seven lesions of iliac vessels. All cases were evaluated immediately and required laparotomy, provisional hemostasis and urgent attendance by a vascular surgeon. Direct suturing was performed in three cases. One aortoiliac bypass and one ilioiliac reversed venous graft were made. Venous lesions were sutured. One case of a point-like perforation of the small bowel was found. There were no deaths and no complications during the postoperative period. DISCUSSION: Important points on this subject are made, and advice is given. There needs to be immediate recognition of the vascular injury, and expert repair by a vascular surgeon is recommended, in order to significantly reduce the degree of complications.

    To evaluate the safety and feasibility of biliary tract reoperation by laparoscopy for the patients with retained or recurrent stones who failed in endoscopic sphincterotomy. A retrospective analysis of data obtained from attempted laparoscopic reoperation for 39 patients in a single institution was performed, examining open conversion rates, operative times, complications, and hospital stay. Out of the 39 cases, 38 (97%) completed laparoscopy, 1 required conversion to open operation because of difficulty in exposing the common bile duct. The mean operative time was 135 min. The mean post-operative hospital stay was 4 d. Procedures included laparoscopic residual gallbladder resection in 3 cases, laparoscopic common bile duct exploration and primary duct closure at choledochotomy in 13 cases, and laparoscopic common bile duct exploration and choledochotomy with T tube drainage in 22 cases. Duodenal perforation occurred in 1 case during dissection and was repaired laparoscopically. Retained stones were found in 2 cases. Postoperative asymptomatic hyperamlasemia occurred in 3 cases. There were no complications due to port placement, postoperative bleeding, bile or bowel leakage and mortality. No recurrence or formation of duct stricture was observed during a mean follow-up period of 18 mo. Laparoscopic biliary tract reoperation is safe and feasible if it is performed by experienced laparoscopic surgeons, and is an alternative choice for patients with choledocholithiasis who fail in endoscopic sphincterectomy.

    Recently, studies have supported the efficacy of treating anxiety disorders utilizing a transdiagnostic, or non-diagnosis-specific, framework (Erickson, D. H. (2003). Group cognitive behavioural therapy for heterogeneous anxiety disorders. Cognitive Behaviour Therapy, 32, 179-186; Garcia, M. S. (2004). Effectiveness of cognitive-behavioural group therapy in patients with anxiety disorders. Psychology in Spain, 8, 89-97; Norton, P. J., & Hope, D. A. (2005). Preliminary evaluation of a broad-spectrum cognitive-behavioral group therapy for anxiety. Journal of Behavior Therapy and Experimental Psychiatry, 36, 79-97). Transdiagnostic group treatment packages focus on the common aspects inherent across the anxiety disorders such as behavioral and cognitive avoidance, and faulty cognitive appraisals of threat potential or meaning (Barlow, D. H., Allen, L. B., & Choate, M. L. (2004). Toward a unified treatment for emotional disorders. Behavior Therapy, 35, 205-230). Although research supports the overall efficacy of transdiagnostic cognitive behavior therapy (CBT) for anxiety disorders (Norton, P. J., & Philipp, L. M. (2008). Transdiagnostic approaches to the treatment of anxiety disorders: A quantitative review. Psychotherapy: Theory, Research, Practice and Training, 45, 214-226), the effect of diagnostically mixed group composition on individual outcomes is less clear. This study investigated the relationship between group composition and treatment outcome within diagnostically heterogeneous groups with the purpose of determining if diagnostic heterogeneity differentially impacted treatment outcome for 84 individuals during a 12-week transdiagnostic cognitive-behavioral group anxiety treatment program (Norton, P. J. (2012a). Group cognitive-behavioral therapy of anxiety: A transdiagnostic treatment manual. New York: Guilford). The diagnostic makeup of the treatment group was examined at the beginning of treatment and at the end of treatment, and the results indicated

    The study is aimed at developing new methods for diagnosing causes of impairment of female reproductive function. An increase of infertility and chronic pelvic pains syndrome, a growing level of latent diseases of this group, as well as a stably high percentage (up to 25% for infertility and up to 60% for the chronic pelvic pains syndrome) of undetermined origin make this research extremely important. As a complementary technique to laparoscopy we propose to use optical coherence tomography. We have acquired OCT images of different parts of fallopian tubes and pelvic peritoneum and analyzed OCT criteria of unaltered tissues. The OCT images of the isthmic part of fallopian tubes and peritoneum have been morphologically verified for pelvic inflammatory diseases (PID) and endometriosis. Changes in the optical properties of the studied organs typical of PID and endometriosis have been investigated. Based on comparative analysis of the OCT data and the results of histological studies OCT criteria of the considered diseases have been developed. Statistical analysis of diagnostic efficacy of OCT in the case of PID has been carried out. High (75-85%) diagnostic accuracy of OCT in PID is shown.

    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

    The cAMP signaling pathway is implicated in bilateral adrenocortical hyperplasias (BAHs), which are often associated with ACTH-independent Cushing syndrome (CS). Although CS is invariably associated with obesity and is frequently associated with PKA signaling defects, we recently reported that its different forms appear to also present with variable weight gain and adiposity. The present study was aimed at characterizing further the phenotypic and molecular differences in periadrenal adipose tissue (PAT) among patients with subtypes of CS, by anthropometric/biochemical analyses and quantification of PKA expression and activity in BAHs in comparison to a non-CS group with aldosterone producing adenomas (APAs). Glucocorticoid levels, serum parameters, and BMI were analyzed among a larger patient cohort including those with different forms of CS, APAs, and Cushing disease. Abdominal CT scans were available for a small subset of patients examined for fat distribution. PAT collected during adrenalectomy was assayed for PKA activity, cAMP, and PKA expression. BMI and BMI z-score were lower in adults with PPNAD with PRKAR1A mutations and in pediatric patients with PPNAD with and without PRKAR1A mutations, respectively. Patients with PPNAD had higher cAMP levels in PAT and different fat distribution. Thus, PKA activity in PAT differed between CS diagnostic groups. Increased cAMP and PKA activity may have contributed to phenotypic differences among subtypes of CS. In agreement with the known roles of cAMP signaling in the regulation of adiposity, patients with PPNAD were less obese than other patients with CS. © Georg Thieme Verlag KG Stuttgart · New York.

    The results of preoperative pelvic examination and eventual ultrasound examination were correlated with the laparoscopic findings in 316 women with acute pelvic pain. The predictive values of normal and abnormal findings at pelvic examination were 46.9 and 82.1%, respectively. 42.1% of the women...... had ultrasound examination performed. This investigation showed to be helpful especially in patients with normal findings at pelvic examination. If ultrasonic findings were abnormal the results at laparoscopy were also abnormal in 90%. On the contrary, normal findings at ultrasound examination did...... not exclude abnormal pelvic findings. The predictive value of normal results at ultrasound examination was 50.0%. This discrepancy between ultrasonic and pelvic findings can be explained by the size of the pelvic masses.

    To compare the effects of obesity on laparoscopy-assisted distal gastrectomy (LADG) and open distal gastrectomy (ODG). A retrospective study was conducted on 249 patients, who underwent LADG and 224 patients who underwent ODG. The regression coefficient of the primary regression equation between operative time and body mass index (BMI) for LADG was greater than ODG; and between blood loss and BMI for LADG was almost the same as ODG. In overweight patients (BMI ≥25), no significant difference was seen between LADG and ODG regarding postoperative complications, and the benefits of the less-invasive nature of LADG were also seen in some parameters. Obesity-associated difficulties are more while performing LADG than during ODG; however, the influence of obesity on LADG decreases with surgical experience. Moreover, even in overweight patients, the benefits of the less-invasive nature of LADG still remain, but the degree of the benefits is smaller than that in nonobese patients.

    2017-02-01

    Quadratus lumborum block has recently been described as an effective and long-lasting analgesic strategy for various abdominal operations, including gynaecological laparoscopy. Despite evidence that the analgesic effect is mediated by indirect paravertebral block and that local anaesthetic spreads to the lumbar paravertebral space, there have been no reports to date of lower limb motor weakness. We present a patient with unilateral hip flexion and knee extension weakness leading to unplanned overnight admission following lateral quadratus lumborum block with 20 ml levobupivacaine 0.25%. The L2 dermatomal sensory loss and hip flexion weakness suggested spread to either the L2 paravertebral space or to the lumbar plexus, causing weakness of the psoas and iliacus muscles and possibly the quadriceps. The duration of motor block was approximately 18 h. This complication should be considered when performing the block, especially in the setting of day-case surgery.

    Biliary lithiasis is an endemic condition in both Western and Eastern countries, in some studies affecting 20% of the general population. In up to 20% of cases, gallbladder stones are associated with common bile duct stones (CBDS), which are asymptomatic in up to one half of cases. Despite the wide variety of examinations and techniques available nowadays, two main open issues remain without a clear answer: how to cost-effectively diagnose CBDS and, when they are finally found, how to deal with them. CBDS diagnosis and management has radically changed over the last 30 years, following the dramatic diffusion of imaging, including endoscopic ultrasound (EUS) and magnetic resonance cholangiography (MRC), endoscopy and laparoscopy. Since accuracy, invasiveness, potential therapeutic use and cost-effectiveness of imaging techniques used to identify CBDS increase together in a parallel way, the concept of "risk of carrying CBDS" has become pivotal to identifying the most appropriate management of a specific patient in order to avoid the risk of "under-studying" by poor diagnostic work up or "over-studying" by excessively invasive examinations. The risk of carrying CBDS is deduced by symptoms, liver/pancreas serology and ultrasound. "Low risk" patients do not require further examination before laparoscopic cholecystectomy. Two main "philosophical approaches" face each other for patients with an "intermediate to high risk" of carrying CBDS: on one hand, the "laparoscopy-first" approach, which mainly relies on intraoperative cholangiography for diagnosis and laparoscopic common bile duct exploration for treatment, and, on the other hand, the "endoscopy-first" attitude, variously referring to MRC, EUS and/or endoscopic retrograde cholangiography for diagnosis and endoscopic sphincterotomy for management. Concerning CBDS diagnosis, intraoperative cholangiography, EUS and MRC are reported to have similar results. Regarding management, the recent literature seems to show better

    Full Text Available Acute abdomen in a diabetic child may cause diagnostic dilemma. Acalculous emphysematous cholecystitis (EC, although reported among critically ill or diabetic adults, is an uncommon occurrence in the children. It may complicate the presentation due to its varied manifestations; especially when associated with other concomitant intra-abdominal inflammatory pathologies. We encountered a rare concurrence of acute EC complicated with pericholecystic fluid collection and secondary appendicitis causing non-specific acute abdomen in an 11-year-old obese boy with insulin-dependent diabetes mellitus. Laparoscopy proved to be a highly useful tool in the diagnosis and treatment of this surgical dilemma.

    We aimed to compare the analgesic effects of low-dose intravenous ketamine with the effects of diclofenac suppositories in acute postoperative pain management in women undergoing gynecologic laparoscopic surgery under general anesthesia. In a double-blind, randomized clinical trial, 80 patients were selected and entered the study. After the induction of general anesthesia, one group received 0.15 mg/kg intravenous ketamine and the other group received a 100-mg rectal diclofenac suppository. The two groups were compared regarding acute pain scores, postoperative morphine requirements, and untoward complications. Pain scores and morphine requirements were lower in the rectal diclofenac suppository group at the 1st, 3rd, and 6th postoperative hours. Higher incidences of postoperative nausea and vomiting (PONV), delusions, and oral secretions were observed in the ketamine group. Diclofenac 100-mg suppositories were more effective in suppressing acute pain than 0.15 mg/kg intravenous ketamine in women undergoing elective gynecologic laparoscopy, with fewer untoward complications.

    Abstract Background The acute abdomen is a frequent entity at the Emergency Department (ED), which usually needs rapid and accurate diagnostic work-up. Diagnostic work-up with imaging can consist of plain X-ray, ultrasonography (US), computed tomography (CT) and even diagnostic laparoscopy. However, no evidence-based guidelines exist in current literature. The actual diagnostic work-up of a patient with acute abdominal pain presenting to the ED varies greatly between hospitals and physicians....

    OBJECTIVE Ventriculoperitoneal (VP) shunt treatment is the main treatment method for hydrocephalus. The traditional operative approach for peritoneal catheter insertion is mini-laparotomy. In recent years, laparoscopy-assisted insertion has become increasingly popular. It seems likely that use of an endoscope could lower the incidence of shunt malfunction. However, there is no consensus about the benefits of laparoscopy-assisted peritoneal catheter insertion. METHODS A systematic search was performed using the PubMed, Embase, ScienceDirect, and Cochrane Library databases. A manual search for reference lists was conducted. The protocol was prepared according to the interventional systematic reviews of the Cochrane Handbook, and the article was written on the basis of the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines. RESULTS Eleven observational trials and 2 randomized controlled trials were included. Seven operation-related outcome measures were analyzed, and 3 of these showed no difference between operative techniques. The results of the meta-analysis are as follows: in the laparoscopy group, the rate of distal shunt failure was lower (OR 0.41, 95% CI 0.25-0.67; p = 0.0003), the absolute effect is 7.11% for distal shunt failure, the number needed to treat is 14 (95% CI 8-23), operative time was shorter (mean difference [MD], -12.84; 95% CI -20.68 to -5.00; p = 0.001), and blood loss was less (MD -9.93, 95% CI -17.56 to -2.31; p = 0.01). In addition, a borderline statistically significant difference tending to laparoscopic technique was observed in terms of hospital stay (MD -1.77, 95% CI -3.67 to 0.13; p = 0.07). CONCLUSIONS To some extent, a laparoscopic insertion technique could yield a better prognosis, mainly because it is associated with a lower distal failure rate and shorter operative time, which would be clinically relevant.

    , and 1 congenital malformations.Conclusions. The incidence of adnexal masses found in this study resembles that found in literature. Laparoscopic surgery is at least as safe as laparotomy. Surgery performed in the first trimester of pregnancy did not increase the risk of worse outcome of pregnancy. A relatively high percentage of borderline malignant and malignant tumours and not enough sensitive ultrasound examination justify the use of invasive diagnostic and surgical treatment of adnexal masses in pregnancy, especially after laparoscopy has become extensively used. Tumours are recommended to be removed laparoscopically after the 12th gestational week, because in this period the removal of the ovary and corpus luteum is not dangerous, the effect of anesthetics on the fetus during organogenesis is avoided, and the uterine size is still appropriate for a safe procedure. For a relatively small number, the management of these cases is recommended to be carried out in centres with appropriate equipment and experience in laparoscopic management of adnexal masses.

    Conventional open procedures have been supplanted in part by less invasive approaches, such as laparoscopic surgery developed for treating gastrointestinal malignancies. However, it is unclear whether laparoscopy-assisted gastric tube reconstruction (LAGT) can attenuate the postoperative systemic inflammatory response after esophagectomy for esophageal cancer. We investigated the postoperative clinical course of the systemic inflammatory response syndrome (SIRS) in patients who underwent an esophagectomy for esophageal cancer by LAGT (LAGT group) and gastric tube reconstruction by conventional open surgery (Open group). Compared with the Open group, the LAGT group had a significantly shorter operative time (539.6 min vs. 639.8 min), shorter duration of postoperative mechanical ventilation (1.1 days vs. 2.8 days), and shorter length of stay in the intensive care unit (2.1 days vs. 4.4 days). The LAGT group also had a significantly shorter SIRS duration (1.4 days vs. 2.7 days), a significantly lower incidence of SIRS, and a smaller number of positive SIRS criteria. Throughout the investigation period, the postoperative white blood cell count was lower in the LAGT group than in the Open group. Additionally, in the LAGT group, the heart rate was lower on each postoperative day (POD), and the respiratory rate was significantly lower on postoperative days (PODs) 1 and 4. There was no difference in postoperative oxygenation, morbidity, and mortality between the groups. The C-reactive protein level on PODs 3 and 4 was significantly lower in the LAGT group than in the Open group. Laparoscopy-assisted gastric tube reconstruction significantly attenuates postoperative SIRS, and it is therefore a potentially less invasive surgical procedure.

    To evaluate right intercostal Veress needle (VN) insertion for laparoscopy in dogs. Longitudinal cohort study. Female dogs (n = 56). The VN was inserted in the last palpable right intercostal space, either 1/3 (Group T; 28 dogs) or mid distance (Group H; 28 dogs) from the xiphoid cartilage to the most caudal extent of the costal arch. Problems encountered during VN insertion and injuries were recorded, graded, and compared between groups, and also between the first and last 20 insertions. Pneumoperitoneum was successfully achieved by VN insertion in 49 (88%) dogs after a single (45 dogs) or 2nd attempt (4 dogs). Frequency of complications was as follows: 20 grade 1 (subcutaneous emphysema, omentum, or falciform injuries); 6 grade 2 (liver or spleen injury), and 1 grade 3 complication (pneumothorax occurred). No significant difference was found between the 2 groups or between the first and last 20 dogs. Right intercostal VN insertion facilitates pneumoperitoneum in dogs with few consequential complications. No significant difference was found between entry sites; however, the mid distance insertion site in the last palpable intercostal space with dog positioned in dorsal recumbency is likely to result in less complications. © Copyright 2012 by The American College of Veterinary Surgeons.

    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.

    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.

    Objective:To analyze the efficacy of laparoscopy and conventional open surgery on immune function and neuroendocrine function in elderly patients with benign ovarian tumor.Methods:A total of 84 cases of elderly patients with benign ovarian tumors were selected, and these patients were divided into observation group and control group with 42 cases each according to random number table method. The observation group was treated with laparoscopy, while the control group was given conventional open surgery. Operative time, blood loss, hospital stays, postoperative levels of T lymphocyte subsets and neuroendocrine function indicators includingβ-endorphin, glucagon and cortisol (COR) were compared between these two groups.Results:Blood loss ((93.25±14.75) mL) and hospital stays ((2.5±0.5) d) in observation group were significantly less than control group, with (110.57±17.36) mL for blood loss and (6.25±1.25) d for hospital stays (P<0.05), respectively. However, operative time in observation group ((90.36±15.14) min) was longer when compared with control group ((85.57±10.95) min) (P<0.05). The levels of CD3+, CD4+ and CD4+/CD8+ on the first and third day after surgery were higher, and the level of CD8+ on the first and third day after surgery was lower in observation group than control group (P<0.05). The levels ofβ-endorphin, glucagon and COR on the first and third day after surgery in observation group were significantly lower than control group (P<0.05).Conclusions:Laparoscopy has a slight influence on immune function and neuroendocrine function, making it a superior therapy for elderly patients with benign ovarian tumors.

    2016-03-01

    High peak airway pressure (Ppeak) and high end-tidal carbon dioxide tension (PETCO2) are the common problems encountered in the obese patients undergoing gynecological laparoscopy with conventional volume-controlled ventilation. This study was designed to investigate whether volume-controlled inverse ratio ventilation (IRV) with inspiratory to expiratory (I:E) ratio of 2:1 could reduce Ppeak or the plateau pressure (Pplat), improve oxygenation, and alleviate lung injury in patients with normal lungs. Sixty obese patients undergoing gynecological laparoscopy were enrolled in this study. After tracheal intubation, the patients were randomly divided into the IRV group (n = 30) and control group (n = 30). They were ventilated with an actual tidal volume of 8 mL/kg, respiratory rate of 12 breaths/min, zero positive end-expiratory pressure and I:E of 1:2 or 2:1. Arterial blood samples, hemodynamic parameters, and respiratory mechanics were recorded before and during pneumoperitoneum. The concentrations of tumor necrosis factor-α, and interleukins 6 and 8 in bronchoalveolar lavage fluid were measured immediately before and 60 minutes after onset of CO2 pneumoperitoneum. IRV significantly increased arterial partial pressure of oxygen, mean airway pressure, and dynamic compliance of respiratory system with concomitant significant decreases in Ppeak and Pplat compared to conventional ventilation with I:E of 1:2 (p obese patients undergoing gynecologic laparoscopy without adverse respiratory and hemodynamic effects. It is superior to conventional ratio ventilation in terms of oxygenation, respiratory mechanics and inflammatory cytokine in obese patients undergoing gynecologic laparoscopy. Copyright © 2015.

    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.

    2014-01-01

    The objectives of this review were to analyze the literature describing the benefits of minimally invasive gynecologic surgery in obese women, to examine the physiologic considerations associated with obesity, and to describe surgical techniques that will enable surgeons to perform laparoscopy and robotic surgery successfully in obese patients. The Medline database was reviewed for all articles published in the English language between 1993 and 2013 containing the search terms "gynecologic laparoscopy" "laparoscopy," "minimally invasive surgery and obesity," "obesity," and "robotic surgery." The incidence of obesity is increasing in the United States, and in particular morbid obesity in women. Obesity is associated with a wide range of comorbid conditions that may affect perioperative outcomes including hypertension, atherosclerosis, angina, obstructive sleep apnea, and diabetes mellitus. In obese patients, laparoscopy or robotic surgery, compared with laparotomy, is associated with a shorter hospital stay, less postoperative pain, and fewer wound complications. Specific intra-abdominal access and trocar positioning techniques, as well as anesthetic maneuvers, improve the likelihood of success of laparoscopy in women with central adiposity. Performing gynecologic laparoscopy in the morbidly obese is no longer rare. Increases in the heaviest weight categories involve changes in clinical practice patterns. With comprehensive and thoughtful preoperative and surgical planning, minimally invasive gynecologic surgery may be performed safely and is of particular benefit in obese patients.

    The objective of this trial was to assess which type of warm-up has the highest effect on virtual reality (VR) laparoscopy performance. The following warm-up strategies were applied: a hands-on exercise (group 1), a cognitive exercise (group 2), and no warm-up (control, group 3). This is a 3-arm randomized controlled trial. The trial was conducted at the department of surgery of the University Hospital Basel in Switzerland. A total of 94 participants, all laypersons without any surgical or VR experience, completed the study. A total of 96 participants were randomized, 31 to group 1, 31 to group 2, and 32 to group 3. There were 2 postrandomization exclusions. In the multivariate analysis, we found no evidence that the intervention had an effect on VR performance as represented by 6 calculated subscores of accuracy, time, and path length for (1) camera manipulation and (2) hand-eye coordination combined with 2-handed maneuvers (p = 0.795). Neither the comparison of the average of the intervention groups (groups 1 and 2) vs control (group 3) nor the pairwise comparisons revealed any significant differences in VR performance, neither multivariate nor univariate. VR performance improved with increasing performance score in the cognitive exercise warm-up (iPad 3D puzzle) for accuracy, time, and path length in the camera navigation task. We were unable to show an effect of the 2 tested warm-up strategies on VR performance in laypersons. We are currently designing a follow-up study including surgeons rather than laypersons with a longer warm-up exercise, which is more closely related to the final task.

    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 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

    Laparoscopy-assisted gastrectomy (LAG) is increasingly performed in Japan by a number of surgeons. As this is a relatively new technique, a training system is important, however there has been little discussion about an educational system for teaching trainees to perform LAG and the ideal training system has not yet been established. Two hundred and sixty-three patients who underwent LAG at the Cancer Institute Hospital were included in this study. In all cases there was standardization of LAG (the way in which the surgical field was formed by the assistant and the way the operator dissected the lymph nodes was determined and all cases were performed using the same laparoscopic procedures) and a step-by-step training system was completed. Specialists performed the surgery in 213 patients (S group) while the remaining 50 patients had their surgery performed by trainees (T group). Early surgical outcomes were compared between specialists and trainees to clarify whether the standardization and our educational system are useful in maintaining the quality of LAG. T-group patients had significantly longer operation times than those of S-group (262.3 +/- 7.3 versus 233.3 +/- 3.7 min), however, the trainees reached the plateau of their learning curve earlier than previously reported. All other early surgical outcomes examined, including intraoperative blood loss (76.7 +/- 35.1 versus 64.9 +/- 7.7 ml), number of retrieved lymph nodes (33.4 +/- 1.4 versus 35.7 +/- 0.8), morbidity (8 versus 14%), and mortality (0% in both groups), were not significantly different between the two groups. The surgical results of T-group were almost equal to those of S-group, showing that our educational system is effective and surgical quality is maintained. Standardized laparoscopic procedures and sufficient intensive experience in the short term are requisites for effectively learning how to perform LAG.

    To evaluate safety and efficacy of laparoscopy-assisted radical gastrectomy (LARG) for advanced gastric cancer patients aged 70 years or older. Clinical data were retrospectively collected from patients with IIA-IIIC gastric cancer who underwent LARG (n = 30) and open radical gastrectomy (ORG, n = 34) in Department of Gastrointestinal Surgery in the Ningbo First Hospital from January 2012 to December 2013. The mean operative time was longer in the LARG group than in the ORG group but there was no statistical difference between the two groups. The intraoperative blood loss (120 ± 52.7 ml vs 227.3 ± 146.9 ml), incidence of postoperative complication (23.0% vs 47%) were lower in the LARG group than those in the ORG group. In addition, the time to first flatus (2.9 ± 0.8 d vs 4.6 ± 1.2 d), time to first ambulation (1.2 ± 0.4 vs 4.1 ± 1.0 d), time of nasogastric intubation (2.5 ± 1.0 d vs 3.5 ± 1.4 d), and postoperative hospital stay (13.0 ± 4.2 d vs 16.9 ± 4.1 d) were significantly shorter in the LARG group than in the ORG group, respectively. No statistical difference in the number of harvested lymph nodes was noted between the two groups (30.2 ± 12.0 vs 28.1 ± 11.8, P > 0.05). LARG is safer, more effective and less invasive for the elderly patients with advanced gastric cancer.

    This study aimed to introduce a method to remove huge ovarian tumors (≥15 cm) intact with single-port laparoscopic surgery (SPLS) using SW Kim's technique and to compare the surgical outcomes with those of laparotomy. Medical records were retrospectively reviewed for patients who underwent either SPLS (n=21) with SW Kim's technique using a specially designed 30×30-cm(2)-sized 3XL LapBag or laparotomy (n=22) for a huge ovarian tumor from December 2008 to May 2016. Perioperative surgical outcomes were compared. In 19/21 (90.5%) patients, SPLS was successfully performed without any tumor spillage or conversion to multi-port laparoscopy or laparotomy. There was no significant difference in patient characteristics, including tumor diameter and total operation time, between both groups. The postoperative hospital stay was significantly shorter for the SPLS group than for the laparotomy group (median, 2 [1 to 5] vs. 4 [3 to 17] days; Phuge ovarian tumors.

    Full Text Available Thirty patients with ovarian dermoid cysts removed by laparoscopic surgery were compared with 42 patients with ovarian dermoid cysts removed by laparotomy, with respect to the selection criteria, surgical procedures, operating time, intraoperative and postoperative complications, blood loss, and hospital stay. Although the operating time for unilateral cystectomy, unilateral salpingo-oophorectomy, and bilateral cystectomy performed by laparoscopic surgery was longer (120.3 ± 43.7 min, mean ± SD than those for the same procedures performed by laparotomy (73.9 ± 21.6 min, p < 0.01, we observed a learning curve with a remarkable declining tendency (linear regression model, p < 0.01. At the end of this study, the times taken for laparoscopic procedures were almost the same as those for laparotomy. Less blood loss (18.2 ± 1.7 ml versus 105.9 ± 84.3 ml, p < 0.01 and shorter hospital stay (5.9 ± 1.9 days versus 12.0 ± 2.9 days, p < 0.01 were also found to be advantages of laparoscopic surgery. This article discusses the technical procedures of laparoscopic surgery. The efficiency and safety of operative laparoscopy as an alternative access route for the management of ovarian dermoid cysts were recognized. We stress that strict criteria for selection of patients should always be followed and the necessity of retraining schedules for gynecologists and nursing staff in the speciality of laparoscopic surgery.

    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.

    The aim of this study was to assess the performance curve for novices training in bimanual tissue manipulation and angled laparoscope navigation, and compare those performances with the performances of experienced laparoscopic surgeons. The Camera Navigation task with a 30 degrees angled laparoscope and the Place Arrow task of the new SimSurgery SEP virtual reality simulator were used. Fourteen medical trainees (no laparoscopy experience) performed four training sessions within one week, including 15 repetitions of each task in total. The experienced participants (>50 procedures & familiar with angled laparoscope) performed each task twice. The performance on both tasks by the novices improved significantly over the training sessions. The experienced participants performed both tasks significantly better than the novices in repetition 3. After repetition 15, the performances of the novices on both tasks were of the same level as the performances of the experienced participants. By training on SimSurgery SEP, medical trainees can extensively improve their skills in navigation with 30 degrees angled laparoscope and bimanual tissue manipulation. Further research should focus on the transfer of skills acquired on the simulator to the clinical setting. Knowledge on proficiency thresholds and training end-points for pre-clinical criterion-based training of different laparoscopic tasks also needs to be extended.

    Recent literature suggests that laparoscopic repair of ventral hernias may have very low recurrence rates. However, laparoscopy may not be feasible in certain situations. We describe an open technique that uses the tension-free retrofascial principles of laparoscopic repair without the need for subcutaneous flaps. Through an incision in the hernia, the peritoneum is entered and adhesions are taken down. A piece of DualMesh (W.L. Gore & Associates, Inc, Newark, Del) is trimmed to fit with a 5-cm circumferential overlap. A vertical incision is made in the mid portion of the mesh. The mesh is fixed in an intraperitoneal retrofascial position using GORE-TEX sutures (W.L. Gore & Associates, Inc). The sutures are brought through the abdominal wall using a laparoscopic suture passer and tied into place on one side of the mesh. That side is then tacked to the posterior fascia with a spiral tacking device. The other side is sutured into place in a similar fashion and then tacked to the fascia by passing the spiral tacking device through the incision in the mesh. The mesh incision is closed with a running GORE-TEX suture. The overlying tissues are closed in layers.

    Full Text Available Introduction: Liver diseases have a high incidence in the whole world. In order to diagnose, stage and follow these diseases it is often necessary the execution of liver biopsy. There are many possible ways to perform the procedure and the rise of transumbilical endoscopic surgery (TUES brings to the medical practice an additional good option. Materials and Methods: The study is prospective, nonrandomised and cohort type. It involves 42 patients who underwent liver biopsy through TUES using conventional video laparoscopic material. Results: Among the patients 18 (42.86% underwent isolated liver biopsy and 24 (57.14% to liver biopsy associated with umbilical hernia repair. Within those, 27 (64.28% were male and 15 (35.71% female. The average body mass index (BMI was of 27.26 kg/m2, 10 were in the normal BMI range, 24 (57.14% were in the overweight range, 6 (14.28% had class I obesity and 2 (4.76% had class II obesity. In none of the cases the procedure was converted to regular video laparoscopy, all the patients were discharged in the day after the procedure and reported a satisfactory aesthetic result. Conclusions: The study shows that liver biopsy using TUES has applicability and good results, including in obese patients that would have a contraindication to other methods.

    Full Text Available Cost-effectiveness in health care management is critical. The situation in debt-stricken Greece is further aggravated by the financial crisis and constant National Health System expense cut-downs. In an effort to minimize the cost of laparoscopy, our department introduced reusable laparoscopic instruments in December 2011. The aim of this study was to assess potential cost reduction of laparoscopic operations in the field of general surgery. Hospital records, invoice lists, and operative notes between January 2012 and December 2013, were retrospectively reviewed and data were collected on laparoscopic procedures, instrument failures, and replacement needs. Initial acquisition cost of 5 basic instrument sets was €21,422. Over the following 24 months, they were used in 623 operations, with a total maintenance cost of €11,487. Based on an average retail price of €490 per set, projected cost with disposable instruments would amount to €305,270, creating savings of €272,361 over the two-year period under study. Despite the seemingly high purchase price, each set amortized its acquisition cost after only 9 procedures and instrument cost depreciated to less than €55 per case. Disposable instruments cost 9 times more than reusable ones, and their high price would almost equal the total hospital reimbursement by social security funds for many common laparoscopic procedures.

  13. "Spaghetti Maneuver": A useful tool in pediatric laparoscopy - Our experience

    2011-01-01

    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.

    Full Text Available Background: Currently, benefits of robotic surgery in patients with benign gynecological conditions remain unclear. In this study, we compared the surgical outcome of robotic and laparoscopic total hysterectomies and evaluated the feasibility of robotic surgery in cases with pelvic adhesions or large uterus. Materials and Methods: A total of 216 patients receiving total hysterectomy via robotic or laparoscopic approach were included in this study. Of all 216 patients, 88 underwent robotic total hysterectomy and 128 underwent laparoscopic total hysterectomy. All cases were grouped by surgical type, adhesion score, and uterine weight to evaluate the interaction or individual effect to the surgical outcomes. The perioperative parameters, including operation time, blood loss, postoperative pain score, time to full diet resumption, length of hospital stay, conversion rate, and surgery-related complications were compared between the groups. Results: Operation time and blood loss were affected by both surgical type and adhesion score. For cases with severe adhesions (adhesion score greater than 4, robotic surgery was associated with a shortened operation time (113.9 ± 38.4 min versus 164.3 ± 81.4 min, P = 0.007 and reduced blood loss (187.5 ± 148.7 mL versus 385.7 ± 482.6, P=0.044 compared with laparoscopy. Moreover, robotic group showed a lower postoperative pain score than laparoscopic group, as the effect was found to be independent of adhesion score or uterine weight. The grade-II complication rate was also found to be lower in the robotic group. Conclusions: Comparing to laparoscopic approach, robotic surgery is a feasible and potential alternative for performing total hysterectomy with severe adhesions.

    To prove feasibility of laparoscopic and vaginal surgical approach in obese patients with endometrial cancer, 81 patients were included retrospectively in 2 Cancer Centres : 41 obese and 40 non obese. We performed hysterectomy with oophorectomy and pelvic lymphadenectomy by laparoscopic and vaginal approach. Operative time was higher for obese patients vs non obese (150 vs 121 minutes, p = 0.01) but pelvic nodes (16.3 vs 16.2), postoperative stay (3.8 [2-8] vs 3.6 days [2-7]), complications and disease-free survival (93 % vs 83 %) were similar. Matching 41 obese patients treated by laparoscopy with 29 obese patients with endometrial cancer treated by laparotomy, hospital stay was shorter in the laparoscopic group (3.8 [2-8] vs 7.4 days [5-10] p obese patients with stage I endometrial adenocarcinoma, laparoscopic approach should be first choice because of similar operative complications and pelvic nodes, shorter hospital stay and less abdominal wall morbidity associated with lower risk to delay adjuvant radiotherapy.

    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

    While there are many reported advantages to laparoscopic surgery compared to open surgery, the impact of a laparoscopic approach on postoperative morbidity in obese patients undergoing rectal surgery has not been studied. Our goal was to determine whether obese patients undergoing laparoscopic rectal surgery experienced the same benefits as non-obese patients. We identified patients undergoing rectal resections using the National Surgical Quality Improvement Project Participant Use Data File. We performed multivariable analyses to determine the independent association between laparoscopy and postoperative complications. A total of 26,437 patients underwent rectal resection. The mean age was 58.5 years, 32.6 % were obese, and 47.2 % had cancer. Laparoscopic procedures were slightly less common in obese patients compared to non-obese patients (36.0 vs. 38.2 %, p = 0.0006). In unadjusted analyses, complications were lower with the laparoscopic approach in both obese (18.9 vs. 32.4 %, p obese (15.6 vs. 25.3 %, p obesity worsened. The likelihood of experiencing a postoperative complication increased by 25, 45, and 75 % for obese class I, obese class II, and obese class III patients, respectively. A laparoscopic approach was associated with a 40 % decreased odds of a postoperative complication for all patients (OR 0.60, 95 % CI 0.56-0.64). Laparoscopic rectal surgery is associated with fewer complications when compared to open rectal surgery in both obese and non-obese patients. Obesity was an independent risk factor for postoperative complications. In appropriately selected patients, rectal surgery outcomes may be improved with a minimally invasive approach.

  18. Surgery for inflammatory bowel disease in the era of laparoscopy

    During the course of inflammatory bowel disease (IBD), surgery may be needed. Approximately 20% of patients with ulcerative colitis (UC) will require surgery, whereas up to 80% of Crohn’s disease (CD) patients will undergo an operation during their lifetime. For UC patients requiring surgery, total proctocolectomy and ileoanal pouch anastomosis (IPAA) is the operation of choice as it provides a permanent cure and good quality of life. Nevertheless a permanent stoma is a good option in selected patients, especially the elderly. Minimally invasive surgery has replaced the conventional open approach in many specialized centres worldwide. Laparoscopic colectomy and restorative IPAA is rapidly becoming the standard of care in the treatment of UC requiring surgery, whilst laparoscopic ileo-cecal resection is already the new gold standard in the treatment of complicated CD of terminal ileum. Short term advantages of laparoscopic surgery includes faster recovery time and reduced requirement for analgesics. It is, however, in the long term that minimally invasive surgery has demonstrated its superiority over the open approach. A better cosmesis, a reduced number of incisional hernias and fewer adhesions are the long term advantages of laparoscopy in IBD surgery. A reduction in abdominal adhesions is of great benefit when a second operation is needed in CD and this influences positively the pregnancy rate in young women undergoing restorative IPAA. In developing the therapeutic plan for IBD patients it should be recognized that the surgical approach to the abdomen has changed and that surgical treatment of complicated IBD can be safely performed with a true minimally invasive approach with great patient satisfaction.

    Technology in hemostasis laboratories has evolved enormously during the last 30 years. Although many scientists and clinicians will remember the traditional tilt-tube techniques to screen for coagulation abnormalities and to monitor anticoagulant therapy, the hemostasis laboratory today uses a variety of modern technologies. These include flow cytometry, chromogenic assays, molecular typing (e.g., polymerase chain reaction), immunologic assays (e.g., enzyme-linked immunosorbent assays), functional assays of specific coagulation proteins, and platelet function analyzers. Although these advances in technology have resulted in greater capability, productivity, sensitivity, specificity, and ultimately, improvement in the clinical care of patients, controversies and limitations remain. This article highlights new and emerging technologies in hemostasis and discusses whether they have improved or are likely to improve laboratory diagnostics by specifically addressing the following: (1) Can new technologies help predict likelihood of thrombosis recurrence? (2) Has an understanding of the role of A Disintegrin-like And Metalloprotease with Thrombo Spondin type 1 motifs (ADAMTS13) in microangiopathy resulted in improved diagnostic methods for this disorder? (3) Does thrombelastography allow better definition of bleeding risk than conventional hemostasis assays, especially in settings of acute hemostatic pathology?

Patients and Methods: This prospective study of ultrasonographic examination in 146 paediatric patients presenting with acute onset abdominal pain at the emergency/paediatric outpatient department section of Jawaharlal Nehru Medical College & Hospital, Aligarh, between June 2006 and December 2007, using 3.75 MHz and 8 MHz transducers of the ADARA (Siemens machine. Results : Common causes of acute abdominal emergencies in pediatric patients as noted on ultrasonography included nonspecific pain (28%, abdominal abscess (21%, acute appendicitis (7% and intussusception (7%. Ultrasonography was diagnostic in 45.2% cases and supportive in 12.3% of the cases. As for as the final outcome, ultrasonography prevented surgery in almost 20% cases and laparotomy was avoided in 7% of the patients as ultrasound guided interventions in the form of abscess aspiration were carried out. Conclusion: Ultrasonography evaluation of children with acute abdominal pain, helps in making significant changes in the management plan of the patients, and also reveals various clinically unsuspected diseases.

    In 2003, following a workshop at the National Institutes of Health, the International Restless Legs Syndrome Study Group (IRLSSG) developed updated diagnostic criteria for restless legs syndrome/Willis-Ekbom disease (RLS/WED). These criteria were integral to major advances in research, notably in epidemiology, biology, and treatment of RLS/WED. However, extensive review of accumulating literature based on the 2003 NIH/IRLSSG criteria led to efforts to improve the diagnostic criteria further. The clinical standards workshop, sponsored by the WED Foundation and IRLSSG in 2008, started a four-year process for updating the diagnostic criteria. That process included a rigorous review of research advances and input from clinical experts across multiple disciplines. After broad consensus was attained, the criteria were formally approved by the IRLSSG executive committee and membership. Major changes are: (i) addition of a fifth essential criterion, differential diagnosis, to improve specificity by requiring that RLS/WED symptoms not be confused with similar symptoms from other conditions; (ii) addition of a specifier to delineate clinically significant RLS/WED; (iii) addition of course specifiers to classify RLS/WED as chronic-persistent or intermittent; and (iv) merging of the pediatric with the adult diagnostic criteria. Also discussed are supportive features and clinical aspects that are important in the diagnostic evaluation. The IRLSSG consensus criteria for RLS/WED represent an international, interdisciplinary, and collaborative effort intended to improve clinical practice and promote further research.

    In the prospect of improved disease management and future clinical trials in Frontotemporal Dementia, it is desirable to share common diagnostic procedures. To this aim, the Italian FTD Network, under the aegis of the Italian Neurological Society for Dementia, has been established. Currently, 85 Italian Centers involved in dementia care are part of the network. Each Center completed a questionnaire on the local clinical procedures, focused on (1) clinical assessment, (2) use of neuroimaging and genetics; (3) support for patients and caregivers; (4) an opinion about the prevalence of FTD. The analyses of the results documented a comprehensive clinical and instrumental approach to FTD patients and their caregivers in Italy, with about 1,000 newly diagnosed cases per year and 2,500 patients currently followed by the participating Centers. In analogy to other European FTD consortia, future aims will be devoted to collect data on epidemiology of FTD and its subtypes and to provide harmonization of procedures among Centers.

    We describe the first clinical case of a total extraperitoneal hernioplasty combined with intestinal resection assisted by laparoscopy for a strangulated Richter femoral hernia. The patient was a 94-year-old woman admitted to the emergency room with signs and symptoms of acute small bowel obstruction. Diagnosis of a strangulated left Richter femoral hernia was only possible during the initial exploratory laparoscopy. The extraperitoneal approach for mesh positioning was performed gaining access through an infraumbilical 12 mm trocar incision, and assistance of two 5 mm laparoscopic ports at the hipogastrium and right flank. Laparoscopy was resumed and segmental intestinal resection with primary anastomosis was performed. The patient recovered without complications and was discharged home at the fourth postoperative day. The total extraperitoneal approach for acute hernia repair was successful in our particular case. However, factors such as laparoscopic surgical experience, careful patient selection, and correct preoperative diagnosis must be considered before studies in the emergency setting.

    Delaying initiation of adjuvant chemotherapy more than 8 weeks after surgical resection for colorectal cancer adversely affects overall patient survival. The effect of a laparoscopic surgical approach on initiation of chemotherapy has not been studied. The goal of this study was to determine if a laparoscopic approach to colon cancer resection affects the timing of adjuvant chemotherapy and outcomes. Patients who underwent curative surgery for stage II or III colon cancer and received adjuvant chemotherapy between 2003 and 2010 were identified from a prospectively maintained database. Patients were categorized according to surgical approach: open or laparoscopic. Patient demographics, clinicopathologic variables, postoperative complications, time from surgery to initiation of chemotherapy, and long-term oncologic outcomes were compared. Age, gender, ASA class, BMI, tumor stage, and postoperative complications were similar for laparoscopic and open cases, while length of stay was 2 days shorter for laparoscopic cases (5.4 vs 7.6 days, p < 0.01). The proportion of patients who received adjuvant chemotherapy more than 8 weeks after surgery did not differ between the groups (35.6 % open vs 38.7 % laparoscopic, p = 0.77). In the open group, delay in chemotherapy after surgery was associated with decreased disease-free and overall survival (p = 0.01, 0.01, respectively). However, delay in chemotherapy more than 8 weeks did not affect disease-free or overall survival in the laparoscopy group (p = 0.93, 0.51, respectively). The benefits of quicker recovery after laparoscopic surgery did not translate into earlier initiation of adjuvant chemotherapy in this retrospective study. However, a laparoscopic approach negated the inferior oncologic outcomes of patients who received delayed initiation of chemotherapy.

    Background 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. Methods 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. Results 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

    Background Laparoscopy has been accepted for years as a management of benign ovarian tumors. The aim of this study was to estimate the feasibility and safety of laparoscopy in diagnosis and management of adnexal masses.Methods A total of 2083 patients with benign adnexal mass were treated by laparoscopy at Peking Union Medical College Hospital from January 2000 to December 2003. Their clinical data were reviewed retrospectively. All the adnexal masses suspicious of malignancy at the time of laparoscopy were sent for frozen section evaluation intraoperatively. The rates of unexpected intracystic vegetation and low malignant potential (LMP) tumor or malignancy were investigated. The sensitivity, specificity, positive predictive value, and negative predictive value of laparoscopic diagnosis for LMP or ovarian malignancies were calculated. The ratios were compared by Chi-square test and the continuous variables were tested using two-tailed t test. Results Of the 2083 patients, 16 had LMP or invasive tumors (0.77%), among which 14 were diagnosed histologically intraoperatively and 2 postoperatively. Fifty-five (2.6%) of the 2083 patients had unexpected intracystic vegetations. Their frozen sections showed benign tumors in 41 (74.5%), LMP tumors in 8 (14.5%), and focal invasive ovarian cancers (stage Ic) in 6 (10.9%). The final pathological diagnosis were benign tumors in 41 (74.5%), LMP tumors 7 (12.7%), and focal invasive ovarian cancers (stage Ic) in 7 (12.7%). Laparoscopy achieved a sensitivity of 87.5%, specificity of 98%, positive predictive value of 25.5%, and negative predictive value of 99.9% in the diagnosis of ovarian malignancies. 2067 cases with benign adnexal masses underwent laparoscopy successfully. No conversion to laparotomy, or intra- and postoperative complications in this series. Of the 16 patients with LMP or invasive ovarian cancer, seven underwent laparoscopic surgery including immediate staging laparoscopy in 3. The mean follow-up was 17.3 months

    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.

    This study was done to evaluate the combination effects of capsicum plaster at the Korean hand acupuncture points K-D2 with prophylactic antiemetic on Postoperative Nausea and Vomiting (PONV). An experimental research design (a randomized, a double-blinded, and a placebo-control procedure) was used. The participants were female patients undergoing gynecologic laparoscopy; the control group (n=34) received intravenous prophylactic ramosetron 0.3mg, while the experimental group (n=34) had Korean Hand Therapy additionally. In the experimental group, capsicum plaster was applied at K-D2 of both 2nd and 4th fingers by means of Korean Hand Therapy for a period of 30 minutes before the induction of anesthesia and removed 8 hours after the laparoscopy. The occurrence of nausea, nausea intensity and need for rescue with antiemetic in the experimental group was significantly less than in the control group 2 hours after surgery. Results of the study show capsicum plaster at K-D2 is an effective method for reducing PONV in spite of the low occurrence of PONV because of the prophylactic antiemetic medication.

    Context: Compact groups of galaxies are entities that have high densities of galaxies and serve as laboratories to study galaxy interactions, intergalactic star formation and galaxy evolution. Aims: The main goal of this study is to search for young objects in the intragroup medium of seven compact groups of galaxies: HCG 2, 7, 22, 23, 92, 100 and NGC 92 as well as to evaluate the stage of interaction of each group. Methods: We used Fabry-Perot velocity fields and rotation curves together with GALEX NUV and FUV images and optical R-band and HI maps. Results: (i) HCG 7 and HCG 23 are in early stages of interaction, (ii) HCG 2 and HCG 22 are mildly interacting, and (iii) HCG 92, HCG 100 and NGC 92 are in late stages of evolution. We find that all three evolved groups contain populations of young blue objects in the intragroup medium, consistent with ages < 100 Myr, of which several are younger than < 10 Myr. We also report the discovery of a tidal dwarf galaxy candidate in the tail of NGC 92. These three ...

    2012-11-01

    Full Text Available Abstract Background The application of laparoscopic surgery for advanced gastric cancer (AGC remains questionable on account of technical difficulty of D2 lymphadenectomy, and there has been few large-scale follow-up results regarding the oncological adequacy of laparoscopic surgery compared with that of open surgeries for AGC. The aim of this study is to evaluate technical feasibility and oncological efficacy of laparoscopy-assisted gastrectomy (LAG for advanced gastric cancer without serosal invasion. Methods From January 2008 to December 2012, 1114 patients with gastric cancer underwent D2 gastrectomy, including 336 T2 and T3 patients in term of depth of invasion. Of all 336 patients, 224 underwent LAG, while open gastrectomy (OG performed on the other 112 patients. The comparison was based on the clinicopathologic characteristics, surgical outcome, and follow-up results. Results There are not significant differences in clinicopathological characteristics between the two groups (P > 0.05. The operation time and first ambulation time was similar in the two groups. However, estimated blood loss, bowel function recovery time and duration of hospital stay were significantly less in the LAG group. No significant difference in morbidity and mortality was found between the LAG group and OG group (11.1% vs. 15.3%, P = 0.266; 0.9% vs. 1.8%, P = 0.859. The mean number of resected lymph nodes (LNS between the LAG group and OG group was similar (30.6 ± 10.1 vs. 30.3 ± 8.6, P = 0.786. Furthermore, the mean number of removed LNS in each station was not significantly different in the distal gastrectomy and total gastrectomy (P > 0.05. No statistical difference was seen in 1 year survival rate (91.5% vs. 89.8% P > 0.05 and the survival curve after surgery between the LAG group and OG group. Conclusion Laparoscopy-assisted D2 radical gastrectomy is feasible, effective and has comparative oncological efficacy compared with

    Full Text Available Abstract Objectives To validate the role of high mobility group box-1(HMGB1 in diagnosis of acute appendicitis (AA with different pathological severity. Methods According to the pathologically diagnosis, 150 patients underwent appendectomies between Jan. 2007 and Dec, 2010 were divided into acute simple, acute suppurative and acute gangrenous appendicitis as group 1, 2 and 3, respectively. Each patient group contains 50 sex and age matched cases to make comparison with 50 healthy volunteers. The mRNA and protein expression levels of serum HMGB1 were determined by real-time quantitative PCR and enzyme linked immunosorbent assay (ELISA. Serum High-sensitivity C-reactive protein (hs-CRP levels were determined by rate nephelometric immunoassay. Results In comparison with health volunteers, relative HMGB1 mRNA levels in group 1, 2 and 3 were significantly increased 3.05 ± 0.51,8.33 ± 0.75 and 13.74 ± 1.09 folds, reflecting a tendency of augmented severity. In accordance, serum protein levels of HMGB1 were 10.97 ± 1.64, 14.42 ± 1.56 and 18.08 ± 2.41 ng/ml in 3 patient groups, which are significantly higher than that of healthy volunteers’ 5.47 ± 0.73 ng/ml. hs-CRP levels were 12.85 ± 3.41, 21.04 ± 1.98 and 31.07 ± 5.46 ng/ml in 3 patients groups compared with 2.06 ± 0.77 ng/ml in controls. The concentrations of HMGB1 and hs-CRP were both positively correlated with disease severity. Conclusion Serum HMGB1 constitutes as a valuable marker in diagnosis of AA. Positively correlated with hs-CRP level, mRNA and protein expression of HMGB1 to a certain extent reflected the severity of AA.

    Background Although Brazilian National Public Health System (BNPHS) has presented advances regarding the treatment for obesity in the last years, there is a repressed demand for bariatric surgeries in the country. Despite favorable evidences to laparoscopy, the BNPHS only performs this procedure via laparotomy. Aim 1) Estimate whether bariatric surgeons would support the idea of incorporating laparoscopic surgery in the BNPHS; 2) If there would be an increase in the total number of surgeries performed; 3) As well as how BNPHS would redistribute both procedures. Methods A panel of bariatric surgeons was built. Two rounds to answer the structured Delphi questionnaire were performed. Results From the 45 bariatric surgeons recruited, 30 (66.7%) participated in the first round. For the second (the last) round, from the 30 surgeons who answered the first round, 22 (48.9%) answered the questionnaire. Considering the possibility that BNPHS incorporated laparoscopic surgery, 95% of surgeons were interested in performing it. Therefore, in case laparoscopic surgery was incorporated by the BNPHS there would be an average increase of 25% in the number of surgeries and they would be distributed as follows: 62.5% via laparoscopy and 37.5% via laparotomy. Conclusion 1) There was a preference by laparoscopy; 2) would increase the number of operations compared to the current model in which only the laparotomy is available to users of the public system; and 3) the distribution in relation to the type of procedure would be 62.5% and 37.5% for laparoscopy laparotomy.

    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 introduction of laparoscopic approach (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.

    Full Text Available Abstract Background Robot-assisted laparoscopy (RL is used in a wide range of operative interventions, but the advantage of this technique over conventional laparoscopy (CL remains unclear. Studies comparing RL and CL are scarce. The present study was performed to test the hypothesis that maiden users master surgical tasks quicker with the robot-assisted laparoscopy technique than with the conventional laparoscopy technique. Methods 20 subjects, with no prior surgical experience, performed three different surgical tasks in a standardized experimental setting, repeated four times with each of the RL and CL techniques. Speed and accuracy were measured. A cross-over technique was used to eliminate gender bias and the experience gained by carrying out the first part of the study. Results The task "tie a knot" was performed faster with the RL technique than with CL. Furthermore, shorter operating times were observed when changing from CL to RL. There were no time differences for the tasks of grabbing the needle and continuous suturing between the two operating techniques. Gender did not influence the results. Conclusion The more advanced task of tying a knot was performed faster using the RL technique than with CL. Simpler surgical interventions were performed equally fast with either technique. Technical skills acquired during the use of CL were transferred to the RL technique. The lack of tactile feedback in RL seemed to matter. There were no differences between males and females.

    Highlights: • Synthesis and processing of PMMA-co-MAA spin-coatings on silicon wafers. • Surface chemistry and morphology as a function of tailored co-polymer structure. • Polymer coatings with controlled number of surface carboxyl groups. - Abstract: The generally accepted strategy in development of bio-diagnostic devices is to immobilize proteins on polymeric surfaces as a part of detection process for diseases and viruses through antibody/antigen coupling. In that perspective, polymer surface properties such as concentration of functional groups must be closely controlled in order to preserve the protein activity. In order to improve the surface characteristics of transparent polymethacrylate plastics that are used for diagnostic devices, we have developed an effective fabrication procedure of polymethylmetacrylate-co-metacrylic acid (PMMA-co-MAA) coatings with controlled number of surface carboxyl groups. The polymers were processed effectively with the spin-coating technique and the detailed control over surface properties is here by demonstrated through the variation of a single synthesis reaction parameter. The chemical structure of synthesized and processed co-polymers has been investigated with nuclear magnetic resonance spectroscopy (NMR) and matrix-assisted laser desorption time-of-flight mass spectrometry (MALDI-ToF-MS). The surface morphology of polymer coatings have been analyzed with atomic force microscopy (AFM) and scanning electron microscopy (SEM). We demonstrate that the surface morphology and the concentration of surface –COOH groups (determined with UV–vis surface titration) on the processed PMMA-co-MAA coatings can be precisely controlled by variation of initial molar ratio of reactants in the free-radical polymerization reaction. The wettability of developed polymer surfaces also varies with macromolecular structure.

    Introduction and aim: Ovarian carcinoma (OC) is a common cancer in the Western Countries, and an important cause of death in patients suffering with gynaecologic malignancies. The majority of patients present with advanced disease at the time of diagnosis. Treatment with debulking surgery followed by chemotherapy is the standard approach while chemotherapy is contemplated when surgery is not possible. A correct pre-operative staging is important to ensure a most appropriate management. Laparoscopy (LPS) is the standard diagnostic tool for the assessment of intraperitoneal infiltration but is invasive and requires general anaesthesia. FDG-PET/CT is increasingly used for staging different types of cancer, and the aim of this study is to assess the value of FDG-PET/CT in staging advanced OC and its sensitivity to detect lesions in different quadrants of the abdominal-pelvic area compared to laparoscopy. Materials and methods: From September 2004 till April 2008, 40 patients with high suspicion of OC were referred to our hospital for diagnostic LPS to explore the possibility of optimal debulking surgery. Those who were not suitable for surgery were referred for chemotherapy. Before chemotherapy, the patients underwent an FDG-PET/CT scan. The findings in 9 quadrants of abdominal-pelvic area (total 360 quadrants) for PET/CT and LPS were recorded and compared. Results: In 14/360 areas (3.8%), surgical evaluation was not possible because of presence of adhesions, thus the number of areas explored by laparoscopy was 346. Tumour was found in 308 quadrants (38 quadrants free of disease). PET/CT was positive in all 40 patients with true negative results in 26/346 quadrants (7.5%), and true positives results in 243/346 quadrants (70.2%). False positive and negative PET/CT results were found in 12/346 and 65/346 quadrants, respectively. False positive PET/CT findings were evenly present in all quadrants. False negative PET/CT findings were present in 31/109 (28.4%) upper

    Obesity is known to be a preoperative risk factor for gastric cancer surgery. This study aimed to investigate the influence of obesity on the surgical outcomes of laparoscopy-assisted distal gastrectomy (LADG) for gastric cancer. The clinical data of 131 patients with gastric cancer from January 2010-December 2013 were analyzed retrospectively. Perioperative outcomes were compared between 43 patients with a body mass index (BMI) ≥30 kg/m(2) (obese group) and 88 patients with a BMI obese group than for the nonobese group (234.1 ± 57.2 min versus 212.2 ± 43.5 min, P = 0.026). There were no statistically significant differences between two groups in terms of intraoperative blood loss, the number of retrieved lymph nodes, postoperative recovery, and postoperative complications (P > 0.05). During the follow-up period of 5 mo-49 mo (average, 36 mo), the overall survival rates were not significantly different between the two groups (80.0% [32/40] versus 81.9% [68/83], P > 0.05). The differences in recurrence and metastasis between the two groups were not statistically significant. Our analysis revealed that LADG can be safely performed in patients with BMI ≥30. The procedure was considered to be difficult but sufficiently feasible. Copyright © 2015 Elsevier Inc. All rights reserved.

    The Nordic Orofacial Test-Screening (NOT-S) was developed as a comprehensive method to assess orofacial function. Results from the screening protocol have been presented in 11 international publications to date. This study reviewed these publications in order to compile NOT-S screening data and create profiles of orofacial dysfunction that characterize various age groups and disorders. NOT-S results of nine reports meeting the inclusion criteria were reviewed. Seven of these studies not only provided data on the mean and range of total NOT-S scores, but also on the most common domains of orofacial dysfunction (highest rate of individuals with dysfunction scores), allowing the construction of orofacial dysfunction profiles based on the prevalence of dysfunction in each domain of NOT-S. The compiled data comprised 669 individuals, which included healthy control subjects (n = 333) and various patient groups (n = 336). All studies reported differences between individuals with diagnosed disorders and healthy control subjects. The NOT-S data could measure treatment effects and provided dysfunction profiles characterizing the patterns of orofacial dysfunction in various diagnoses. This review corroborates previous results that the NOT-S differentiates well between patients and healthy controls and can also show changes in individuals after treatment. NOT-S could be used as a standard instrument to assess orofacial dysfunction, evaluate the outcomes of oral habilitation and rehabilitation and improve comparability in clinical practice and research.

    CT and MRI are both used for abdominal staging of pediatric renal tumors. The diagnostic performance of the two modalities for local and regional staging of renal tumors has not been systematically evaluated. To compare the diagnostic performance of CT and MRI for local staging of pediatric renal tumors. The study population was derived from the AREN03B2 study of the Children's Oncology Group. Baseline abdominal imaging performed with both CT and MRI within 30 days of nephrectomy was available for retrospective review in 82 renal tumor cases. Each case was evaluated for capsular penetration, lymph node metastasis, tumor thrombus, preoperative tumor rupture, and synchronous contralateral lesions. The surgical and pathological findings at central review were the reference standard. The sensitivity of CT and MRI for detecting capsular penetration was 68.6% and 62.9%, respectively (P = 0.73), while specificity was 86.5% and 83.8% (P = 1.0). The sensitivity of CT and MRI for detecting lymph node metastasis was 76.5% and 52.9% (P = 0.22), and specificity was 90.4% and 92.3% (P = 1.0). Synchronous contralateral lesions were identified by CT in 4/9 cases and by MRI in 7/9 cases. CT and MRI have similar diagnostic performance for detection of lymph node metastasis and capsular penetration. MR detected more contralateral synchronous lesions; however these were present in a very small number of cases. Either modality can be used for initial loco-regional staging of pediatric renal tumors. (orig.)

Studies clearly documenting a comparison between robotic surgery and laparoscopy or between robotic surgery and laparotomy for endometrial cancer were selected. The outcome measures included operating time (OT, number of complications, length of hospital stay (LOHS, estimated blood loss (EBL, number of transfusions, total lymph nodes harvested (TLNH, and number of conversions. Pooled odds ratios and weighted mean differences with 95% confidence intervals were calculated using either a fixed-effects or random-effects model.Twenty-two studies were included in the meta-analysis. These studies involved a total of 4420 patients, 3403 of whom underwent both robotic surgery and laparoscopy and 1017 of whom underwent both robotic surgery and laparotomy. The EBL (p = 0.01 and number of conversions (p = 0.0008 were significantly lower and the number of complications (p<0.0001 was significantly higher in robotic surgery than in laparoscopy. The OT, LOHS, number of transfusions, and TLNH showed no significant differences between robotic surgery and laparoscopy. The number of complications (p<0.00001, LOHS (p<0.00001, EBL (p<0.00001, and number of transfusions (p = 0.03 were significantly lower and the OT (p<0.00001 was significantly longer in robotic surgery than in laparotomy. The TLNH showed no significant difference between robotic surgery and laparotomy.Robotic surgery is generally safer and more reliable than laparoscopy and laparotomy for patients with endometrial cancer. Robotic surgery is associated with significantly lower EBL than both laparoscopy and laparotomy; fewer conversions but more complications than laparoscopy; and shorter LOHS, fewer complications, and fewer transfusions but a longer OT

    Hans Christian Jacobaeus performed the first clinical laparoscopic surgery in Stockholm. This pioneering procedure was based on the animal experiments of Georg Kelling (1866-1945), a German physician from Dresden, who performed the first laparoscopic intervention in 1901 using a Nitz cystoscope in a dog. In 1910, Jacobaeus published his initial experiences with laparoscopic surgery in the Münchner Medizinischen Wochenschrift under the title "The Possibilities for Performing Cystoscopy in Examinations of Serous Cavities." He used this technique for diagnostic purposes in undefined abdominal complaints and functional impairment. Jacobaeus was the first who pointed out the possibility of injuring organs, especially the intestines, by inserting the trocar. In 1910, Jacobaeus recognized the immense diagnostic and therapeutic possibilities of laparoscopic surgery, as well as its difficulties and limits. He also was the first to realize the need for initial endoscopic training in animals and corpses. He promoted the development of special laparoscopic instruments to optimize and simplify the procedure.

    Full Text Available Background: Chlamydia trachomatis infections are the most prevalent sexually transmittedbacterial infections (STI in the world that lead to a cause of tubal factor infertility in women. Theaim of this study is to determine the presence of C.trachomatis by polymerase chain reaction (PCRand ELISA.Materials and Methods: Endocervical swabs were collected from 80 women; 22 of them wereasymptomatic and 58 symptomatic. Samples were examined by PCR designed to detect Chlamydialplasmid using specific KL1 and KL2 primers. Serum IgG and IgA antibodies to C.trachomatiswere detected by ELISA. Since elevated CRP levels are a marker for inflammation, the presence ofC- Reactive protein (CRP has also been evaluated in all samples.Results: The rate of C.trachomatis infection by PCR was revealed to be 27.2% and 18.9% inasymptomatic and symptomatic women, respectively The χ2 test shows no significant difference(p value= 0.22. Serological screening was done on all samples. The high level of IgG and IgAto C.trachomatis infection was 29.4% and 17.6%, respectively. The presence of high levels ofCRP, as a serological marker of persistence infection, was 31.8% and 34.4% in asymptomaticand symptomatic women, respectively. The high rate of CRP level in the samples indicates acuteinfections in both groups.Conclusion: Genital C.trachomatis infection is the leading cause of tubal factor infertility. Thepresent study shows that C.trachomatis infection could be present in symptomatic as well asasymptomatic women. Therefore, a screening test for C.trachomatis infection is recommended forall women who refer to gynecologic outpatient departments in Isfahan and other parts of Iran.

    Full Text Available Background: Streptococcus Pyogenes (group A streptococcus, GAS is the most important cause of bacterial pharyngitis in children and adolescents. Acute pharyngitis is one of the most common conditions in all ages but it is most common in children. Over diagnosis of acute pharyngitis represents one of the major causes of antibiotic abuse. The goal of this study is to make an estimate of the frequency of group A streptococcus in sore throat patients in Farshchian hospital emergency department and clinic in Hamadan. Methods: For estimation of the clinical features role in diagnosis of streptococcal sore throat, we took samples of 100 patients with average age of 32.96±29.86 years with sore throat. We took samples from pharynx and used standard methods of bacteriology in order to detect streptococcus. Results: Group A Streptococcus (GAS accounts for 3 percent of all cases of pharyngitis. Clinically, all of the patients had sore throat. The percent breakdowns are as follows: 30% had exudate, 78% had fever, 8% had lymphadenopathy and 7.7 percent of exudative pharyngitis was streptococcal. The cost for unnecessary antibiotic therapy for every single patient who had negative pharynx culture was approximately 32160 Rails. Conclusion: The low frequency of streptococcus pharyngitis in treated patients reveal that diagnosis based on clinical features is not reliable. We recommend use of other diagnostic methods such as Rapid Antigen Detection Tests (RATs. Only reliable and scientific protocols for antibiotic to therapy.

    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.

    The aim of this study was to introduce and examine a modified mechanical end-to-side esophagogastrostomy method ("reverse-Tornado" anastomosis) in laparoscopy-assisted proximal gastrectomy. Five patients with gastric cancer who underwent laparoscopy-assisted proximal gastrectomy were analyzed retrospectively. Esophagogastrostomy in the anterior wall was performed in three patients, and esophagogastrostomy in the posterior wall was performed in two patients. Clinicopathological features, operative outcomes (operative time, operative blood loss), and postoperative outcomes (complications, postoperative hospital stay, reflux esophagitis) were evaluated. Operative time was normal (278 min). There was no marked operative blood loss, postoperative complications, prolonged hospital stay, or reflux esophagitis. Esophagogastrostomy was completed in a normal time with reverse-Tornado anastomosis. This method can be safe and can enable good postoperative quality of life. © 2016 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and John Wiley & Sons Australia, Ltd.

    Full Text Available Background. Laparoscopic hysterectomy has proved to be a safe alternative to open surgery in women with benign indications. Few studies compare laparotomy and laparoscopy in gynecologic oncology, and the objective of this study was to analyze the feasibility and development of laparoscopic surgery in endometrial cancer patients. Material and Methods. Records from all women having a hysterectomy due to premalignant or malignant endometrial changes during the years 2002–2009 were examined retrospectively. Results. A total of 521 hysterectomies were performed during the study period. Laparoscopy was performed in about 20% of the cases in the first two years, increasing to 83% in the last year of the period. Moreover, the laparoscopic technique was increasingly applied in older women, more obese women and in women with high-risk preoperative diagnosis, without increasing the complication rate. Conclusions. As for benign indications, laparoscopic hysterectomy in endometrial cancer patients should be preferred whenever possible.

    Success in improving treatment outcomes in childhood cancer has been achieved almost exclusively through multicenter and multidisciplinary clinical and applied research over several decades. While biologically rational as well as empirical approaches have led to combination chemotherapy and multimodality approaches to therapy, which have given rise to evidence-based practice standards, similar scientific rigor has not always been as evidently applied to modalities utilized to assess initial disease burden and, more important, response to investigational approaches to therapy. As the empirical approach to therapeutic advances has likely maximized its benefit, future progress will require translation of biologic discovery most notably from the areas of genomics and proteomics. Hence, attempts to improve efficacy of therapy will require a parallel effort to minimize collateral damage of future therapeutic approaches, and such a parallel approach will mandate the continued dependence on advances in diagnostic imaging for improvements in staging methodologies to best define risk groups for risk-adjusted therapy. In addition, anatomic and functional assessment of response and surveillance for disease recurrence will require improved understanding of the biology as well as natural history of individual diseases, which one hopes will better inform investigators in designing trials. Clinical and research expertise is urgently needed in the selection of specific imaging studies and frequencies that best assess a response as well as to define disease-free intervals. Despite limited resources to develop sufficient infrastructure, emphasis on enabling early assessment of new technology to minimize risks associated with treatment advances and with those critical diagnostic and staging procedures must continue to be a focus of pediatric cancer clinical research.

    International Prognostic Scoring Systems are used to determine the individual risk profile of myelodysplastic syndrome patients. For the assessment of International Prognostic Scoring Systems, an adequate chromosome banding analysis of the bone marrow is essential. Cytogenetic information is not available for a substantial number of patients (5%–20%) with dry marrow or an insufficient number of metaphase cells. For these patients, a valid risk classification is impossible. In the study presented here, the International Prognostic Scoring Systems were validated based on fluorescence in situ hybridization analyses using extended probe panels applied to cluster of differentiation 34 positive (CD34+) peripheral blood cells of 328 MDS patients of our prospective multicenter German diagnostic study and compared to chromosome banding results of 2902 previously published patients with myelodysplastic syndromes. For cytogenetic risk classification by fluorescence in situ hybridization analyses of CD34+ peripheral blood cells, the groups differed significantly for overall and leukemia-free survival by uni- and multivariate analyses without discrepancies between treated and untreated patients. Including cytogenetic data of fluorescence in situ hybridization analyses of peripheral CD34+ blood cells (instead of bone marrow banding analysis) into the complete International Prognostic Scoring System assessment, the prognostic risk groups separated significantly for overall and leukemia-free survival. Our data show that a reliable stratification to the risk groups of the International Prognostic Scoring Systems is possible from peripheral blood in patients with missing chromosome banding analysis by using a comprehensive probe panel (clinicaltrials.gov identifier:01355913).

    Due to the proliferation of disciplines employing fluoroscopy as their primary imaging tool and the prolonged extensive use of fluoroscopy in interventional and cardiovascular angiography procedures, "dose-area-product" (DAP) meters were installed to monitor and record the radiation dose delivered to patients. In some cases, the radiation dose or the output value is calculated, rather than measured, using the pertinent radiological parameters and geometrical information. The AAPM Task Group 190 (TG-190) was established to evaluate the accuracy of the DAP meter in 2008. Since then, the term "DAP-meter" has been revised to air kerma-area product (KAP) meter. The charge of TG 190 (Accuracy and Calibration of Integrated Radiation Output Indicators in Diagnostic Radiology) has also been realigned to investigate the "Accuracy and Calibration of Integrated Radiation Output Indicators" which is reflected in the title of the task group, to include situations where the KAP may be acquired with or without the presence of a physical "meter." To accomplish this goal, validation test protocols were developed to compare the displayed radiation output value to an external measurement. These test protocols were applied to a number of clinical systems to collect information on the accuracy of dose display values in the field.

    Neuraxial anesthesia in upper abdominal laparoscopic surgery decreases perioperative morbidity and mortality. However, shoulder pain is common and difficult to control. Use of a major opioid (e.g., fentanyl) for the control of this event may depress respiratory function. This is why we believe that a safe and effective therapeutic control of this disease pain is a multimodal analgesic scheme which we have called infusional therapy. To compare various schemes for controlling shoulder pain secondary to pneumoperitoneum. Nonrandomized clinical trial with 56 patients ASA I-II divided into four groups undergoing laparoscopic cholecystectomy. Group I (n= 15) managed with ketorolac 1 mg kg, group II (n = 12) ketoprofen 100 mg, group III (n = 14) ketoprofen 50 mg + 50 mg tramadol, and group IV (n = 15) ketoprofen 100 mg + 100 mg tramadol. The following ariables were analyzed: presence and intensity of pain, analgesia rescue and operative time. Group I had more shoulder pain events compared to other groups (p= 0.002) in the same way the group IV required less rescue analgesia (p= 0.034). preemptive analgesia to infusional therapy with ketoprofen-tramadol at doses of 100 mg each is safe for laparoscopic surgery.

    The aetiological assessment of an infertile couple includes several complementary biological and morphological examinations. Initial exploration of the female genital tract requires the performance of pelvic ultrasound and hysterosalpingography. The value of systematic laparoscopy in infertility assessment is still subject to debate. The aim of the present review is to evaluate arguments against the systematic use of laparoscopy and to define the place of the other tests as Chlamydia Trachomatis serology, hysterosalpingosonography and MR-IRM. In our opinion, laparoscopy is of course indicated in infertility assessments not only when anomalies are revealed by hysterosalpingography but also in the following circumstances: past history of infection (especially a positive Chlamydia antibody blood test) and/or pelvic surgery (a significant risk of adhesions), unexplained secondary infertility, unexplained infertility after the age of 38 (when choosing between artificial insemination and direct enrolment in an IVF programme) and failure of 3 cycles of good-quality intra-uterine inseminations (with ovarian stimulation and a sufficient number of spermatozoids).

    Irrigation with taurolidine after laparoscopy decreases tumor growth in colon carcinoma. In pancreatic cancer subcutaneous therapy with octreotide decreases oxidative stress and carcinogenesis as well. However, it is still unclear, whether irrigation with taurolidine or octreotide after laparoscopic pancreatic biopsy reduces tumor growth in pancreatic cancer as well. In 60 Syrian hamsters ductal pancreatic adenocarcinoma was induced by weekly injection of 10mg/kg body weight N-nitrosobis-2-oxopropylamine s.c. for 10 weeks. In week 16 laparoscopic pancreatic biopsy by use of carbon dioxide was performed (gr. 1, n = 20) with subsequent laparoscopic irrigation with taurolidine (gr. 2, n = 20) or octreotide (gr. 3, n = 20). In week 25 hamsters were sacrificed. Our results show that macroscopic visible primary tumors were found in only one animal of the taurolidine group (5.9%), compared to 42.1% in the saline and 62.5% in the octreotide group (Ptaurolidine after pancreatic biopsy inhibited tumor growth in ductal pancreatic adenocarcinoma.

    This study compared surgical outcomes between patients undergoing laparoscopy-assisted distal gastrectomy (LADG) and those undergoing open distal gastrectomy (ODG) from the viewpoint of obesity. Between June 2002 and May 2008, 146 patients with preoperatively diagnosed early gastric cancer who underwent LADG (n = 90) or ODG (n = 56) were enrolled in this study and compared in terms of clinicopathological findings and operative outcome. The visceral fat area (VFA) and subcutaneous fat area (SFA) were assessed as identifiers of obesity using FatScan software. The relationship between obesity and operative outcomes after LADG and ODG was evaluated. There were no significant correlations between intraoperative blood loss (IBL) and any obesity-related factors, or between operation time (OT) and any obesity-related factors in the LADG group. There was a significant correlation between IBL and BMI (r = 0.486, P = 0.0001), IBL and VFA (r = 0.456, P = 0.0003), IBL and SFA (r = 0.311, P = 0.0193), OT and BMI (r = 0.406, P = 0.0017), OT and VFA (r = 0.314, P = 0.0178), and between OT and SFA (r = 0.382, P = 0.0034) in the ODG group. LADG may be a useful operative manipulation that is not influenced by obesity, whereas ODG may be influenced by obesity even after reaching the surgical plateau. (c) 2010 Wiley-Liss, Inc.

    Full Text Available Background: Laparoscopic resection (LR offers significant advantages compared to open resections for gastric gastrointestinal stromal tumours (GISTs. We aimed to evaluate whether LR outcomes jeopardised short and long-term outcomes of patients with large GISTs. Patients and Methods: Among 50 patients undergoing surgery for gastric GISTs, 12 underwent LR for large GISTs (>5 cm. Their characteristics, perioperative results and survival were retrospectively compared to those of 22 patients who underwent LR for 'small GIST'. Results: The two groups were similar regarding demographics, rate of wedge resection and mean blood loss. No patient required transfusion or conversion. Operative time was significantly increased in the 'large GIST' group (160 min vs 112 min, P = 0.001. Mean tumour size was significantly lower in the 'small GIST' group (8.4 cm vs 2.4 cm, P = 0.0001. Resection margins were negative. The mortality rate was nil and the overall morbidity rates was similar in both groups. Median length of hospital stay was significantly increased in the 'large GIST' group (7 days vs 5 days, P = 0.004. Median follow-up was 47 months and one patient in the 'small GIST' group developed recurrence and died during follow-up 11 years after surgery. No patient died during follow-up. Conclusions: LR for large GISTs is safe and technically feasible and does not negatively influence the oncologic course. Prospective randomised trials should be performed before using this approach in routine surgical care.

    Laparoscopy assisted distal gastrectomy (LADG) for gastric cancer has been rapidly adopted for the treatment of both early and advanced gastric cancers which need lymph node dissection, but remains difficult procedure, especially in patients with obesity. We evaluated the impact of obesity on short- and long-term outcomes of LADG for gastric cancer. We retrospectively investigated 243 patients who underwent LADG for gastric cancer between January 2007 and December 2014. The patients were classified based on their body mass index (BMI) into the Obese (BMI ≥ 25) and Non-Obese (BMI Obese Group. Fewer lymph nodes were retrieved in the Obese Group (38 ± 23.7 vs. 47.5 ± 24.3; P = 0.004). No differences were evident in postoperative complication rate (20% vs. 17%; P = 0.688) or the duration of postoperative hospital stay (9 ± 8.5 vs. 9 ± 5.1 days; P = 0.283) between the two groups. In the Obese Group, the 5-year overall survival rate was significantly lower than in the Non-Obese Group (67.6% vs. 90.3%; P = 0.036). Furthermore, 5-year disease-specific survival was significantly lower in the Obese Group than in the Non-Obese Group (72.7% vs. 94.9%; P = 0.015). LADG in patients with obesity could be performed as safe as in patients without obesity, with comparable postoperative results. But obesity may be a poor prognostic factor in gastric cancer.

    Pain and postoperative nausea and vomiting (PONV) are common problems after gynaecologic laparoscopy. Two recent studies have shown that morphine requirements and PONV are lower when an LMA ProSeal™ is used, rather than an endotracheal tube (ETT), for female patients undergoing breast and gynaecological surgery. We conducted a patient and observer-blinded randomised controlled trial, recruiting non-obese women without gastro-oesophageal reflux undergoing laparoscopic gynaecological surgery. Patients received a standardised relaxant general anaesthetic and then were randomised to receive either an LMA ProSeal or an endotracheal tube. Patients were assessed at two and 24 hours post-anaesthesia. The primary outcome was postoperative pain score and secondary endpoints included morphine consumption, postoperative emesis and adverse upper airway symptoms. We recruited 116 patients to the study, 57 patients in the ETT group and 59 patients in the LMA ProSeal group. The patients were similar in demographic and surgical characteristics. At two hours, the ETT group was similar to the LMA ProSeal group in regards to pain scores (Visual Analogue Scale 3.0 vs 3.5, P=0.86), morphine consumption (7.2 vs 7.4 mg, P=0.56) and PONV (47.4 vs 47.5%, P=0.99). After 24 hours, pain scores and PONV rates were also similar. No significant difference in rates of sore throat or dysphagia was observed between the ETT and LMA ProSeal groups. No significant complications were attributable to either airway device. The LMA ProSeal did not decrease pain or PONV in patients undergoing gynaecological laparoscopy when compared to endotracheal intubation.

    Introduction With the trend of increasing incidence of autoimmune diseases, laboratories are faced with exponential growth of the requests for tests relating the diagnosis of these diseases. Unfortunately, the lack of laboratory personnel experienced in this specific discipline of laboratory diagnostic, as well as an unawareness of a method limitation often results in confusion for clinicians. The aim was to gain insight into number and type of Croatian laboratories that perform humoral diagnostics with the final goal to improve and harmonize laboratory diagnostics of autoimmune diseases in Croatia. Materials and methods In order to get insight into current laboratory practice two questionnaires, consisting of 42 questions in total, were created. Surveys were conducted using SurveyMonkey application and were sent to 88 medical biochemistry laboratories in Croatia for the first survey. Out of 33 laboratories that declared to perform diagnostic from the scope, 19 were selected for the second survey based on the tests they pleaded to perform. The survey comprised questions regarding autoantibody hallmarks of systemic autoimmune diseases while regarding organ-specific autoimmune diseases was limited to diseases of liver, gastrointestinal and nervous system. Results Response rate was high with 80 / 88 (91%) laboratories which answered the first questionnaire, and 19 / 19 (1.0) for the second questionnaire. Obtained results of surveys indicate high heterogeneity in the performance of autoantibody testing among laboratories in Croatia. Conclusions Results indicate the need of creating recommendations and algorithms in order to harmonize the approach to laboratory diagnostics of autoimmune diseases in Croatia.

    Objective: To evaluate the performance of T cell enzyme-linked immuno-spot assay (T-SPOT) on peripheral blood in combination with adenosine deaminase (ADA) on pleural fluid for diagnosis of tuberculous (TB) pleurisy within different age groups. Methods: The data of patients with pleural effusion from the Department of Pulmonary and Critical Care Medicine of the First Affiliated Hospital of Wenzhou Medical University from April 2012 to November 2016 were retrospectively analyzed, and the diagnoses of these patients were histopathologically confirmed through medical thoracoscopy. The cases who had confirmed diagnosis, in the same time, received peripheral blood T-SPOT.TB were enrolled. The performance of peripheral blood T-SPOT.TB in combination with pleural fluid ADA on diagnosing TB pleurisy in the younger patients (16-59 years old) and elderly patients (≥60 years old) were analyzed respectively. The sensitivity, specificity and the receiver operating characteristic (ROC) curve were adopted for statistical analysis. Results: A total of 448 cases were finally enrolled, 341(76.1%) confirmed with TB pleurisy, 224 males, 117 females, (47±19) years old; and 107 (23.9%) classified as non-TB pleurisy, 65 males, 42 females, (61±14) years old. There were 285 cases who were classified as younger group, and the other 163 cases were classified as elderly group. The sensitivity and specificity of peripheral blood T-SPOT.TB were 85.4% (204/239) and 71.7% (33/46) in the younger patients, 76.5% (78/102) and 59.0% (36/61) respectively in the elderly patients. The sensitivity of peripheral blood T-SPOT.TB in the younger patients was significantly higher than that in the elderly patients (P=0.047). The sensitivity and specificity were 99.2% and 95.7% in combination with peripheral blood T-SPOT.TB and pleural fluid ADA respectively in the younger patients. The area under ROC curve (AUC) of T-SPOT.TB in the younger patients was 0.833, AUC of T-SPOT.TB combined with ADA was 0

    Full Text Available Abstract Background Two criteria based on a 2 h 75 g OGTT are being used for the diagnosis of gestational diabetes (GDM, those recommended over the years by the World Health Organization (WHO, and those recently recommended by the International Association for Diabetes in Pregnancy Study Group (IADPSG, the latter generated in the HAPO study and based on pregnancy outcomes. Our aim is to systematically review the evidence for the associations between GDM (according to these criteria and adverse outcomes. Methods We searched relevant studies in MEDLINE, EMBASE, LILACS, the Cochrane Library, CINHAL, WHO-Afro library, IMSEAR, EMCAT, IMEMR and WPRIM. We included cohort studies permitting the evaluation of GDM diagnosed by WHO and or IADPSG criteria against adverse maternal and perinatal outcomes in untreated women. Only studies with universal application of a 75 g OGTT were included. Relative risks (RRs and their 95% confidence intervals (CI were obtained for each study. We combined study results using a random-effects model. Inconsistency across studies was defined by an inconsistency index (I2 > 50%. Results Data were extracted from eight studies, totaling 44,829 women. Greater risk of adverse outcomes was observed for both diagnostic criteria. When using the WHO criteria, consistent associations were seen for macrosomia (RR = 1.81; 95%CI 1.47-2.22; p 2 ≥ 73%. Magnitudes of RRs and their 95%CIs were 1.73 (1.28-2.35; p = 0.001 for large for gestational age; 1.71 (1.38-2.13; p Conclusions The WHO and the IADPSG criteria for GDM identified women at a small increased risk for adverse pregnancy outcomes. Associations were of similar magnitude for both criteria. However, high inconsistency was seen for those with the IADPSG criteria. Full evaluation of the latter in settings other than HAPO requires additional studies.

    2015-01-01

    Background and Objectives: In recent years, 2 modifications of laparoscopic transabdominal preperitoneal (TAPP) inguinal hernia repair—needlescopic (nTAPP) surgery and single-port (sTAPP) surgery—have greatly improved patient outcomes over traditional approaches. For a comparison of these 2 modifications, we sought to investigate and compare the extent of surgical trauma and postoperative consequences for the abdominal wall in these two procedures. Methods: In a retrospective study, 50 nTAPP and 35 sTAPP procedures occurring at a community hospital from November 1, 2009, through July 31, 2012 were reviewed. Intraoperative data, including length of the umbilical skin incision and operative time, were recorded. A follow-up evaluation included investigation of hernia recurrence, postoperative pain, abdominal wall mobility, cosmetic satisfaction, and period of sick leave. Results: The mean umbilical skin incision was 13 ± 4 mm in nTAPP vs 27 ± 3 mm in sTAPP (P < .001). The nTAPP procedure required less operating time than the sTAPP procedure (54.8 ± 16.9 minutes vs 85.9 ± 19.7 minutes; P < .001). The mean immediate postoperative pain score on the visual analog scale was 2.7 ± 2.1 in the nTAPP group and 4.4 ± 1.9 in the sTAPP group (P = .016). In addition, patients who underwent nTAPP had a shorter period of sick leave (11.2 ± 8.4 days vs 24.1 ± 20.1 days; P = .02). At the follow-up evaluation after approximately 30 months, abdominal wall mobility and cosmetic satisfaction were equally positive, with no hernia recurrence. Conclusion: In patients with uncomplicated inguinal hernia, the nTAPP procedure, with less surgical trauma and operating time, has distinct advantages in reduction of immediate postoperative pain and sick leave time.

    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.

    Trocar-site hernias are rare complications of laparoscopic surgery. Although trocar-site hernias occur more often at >10-mm sites, hernias can still develop at 5-mm sites after laparoscopy and can lead to serious complications. The primary objective of this review is to summarize the current medical literature pertaining to the clinical presentation and predisposing risk factors of trocar-site hernias at 5-mm sites after laparoscopy. A total of 295 publications were identified, 17 (5.76%) of which met the inclusion criteria. Twenty-seven patients with trocar-site hernias were identified after laparoscopic cases. The median age (interquartile range) for all adult patients with trocar-site hernias was 63 years (interquartile range, 39.5-66.5 years). Eight of the 18 patients (44.4%) undergoing gynecologic laparoscopy were parous although details of parity were not reported in most publications. Simple manual reduction or laparoscopic reduction with fascial closure (21 patients [84%]) was used more often compared with exploratory laparotomy (4 patients [16%], p manipulation can extend 5-mm fascial incisions, thereby increasing the risk of trocar-site hernias. Parous women older than 60 years may have unrecognized fascial defects, which confer a higher risk of trocar-site hernias after laparoscopic surgery, even in the absence of incision manipulation or prolonged surgical duration. Such patients may benefit from closure of 5-mm fascial incisions although prospective data are required to validate the overall generalizability of this management strategy.

    Full Text Available Abstract Background The Theoretical Domains Framework (TDF was developed to investigate determinants of specific clinical behaviors and inform the design of interventions to change professional behavior. This framework was used to explore the beliefs of chiropractors in an American Provider Network and two Canadian provinces about their adherence to evidence-based recommendations for spine radiography for uncomplicated back pain. The primary objective of the study was to identify chiropractors’ beliefs about managing uncomplicated back pain without x-rays and to explore barriers and facilitators to implementing evidence-based recommendations on lumbar spine x-rays. A secondary objective was to compare chiropractors in the United States and Canada on their beliefs regarding the use of spine x-rays. Methods Six focus groups exploring beliefs about managing back pain without x-rays were conducted with a purposive sample. The interview guide was based upon the TDF. Focus groups were digitally recorded, transcribed verbatim, and analyzed by two independent assessors using thematic content analysis based on the TDF. Results Five domains were identified as likely relevant. Key beliefs within these domains included the following: conflicting comments about the potential consequences of not ordering x-rays (risk of missing a pathology, avoiding adverse treatment effects, risks of litigation, determining the treatment plan, and using x-ray-driven techniques contrasted with perceived benefits of minimizing patient radiation exposure and reducing costs; beliefs about consequences; beliefs regarding professional autonomy, professional credibility, lack of standardization, and agreement with guidelines widely varied ( social/professional role & identity; the influence of formal training, colleagues, and patients also appeared to be important factors ( social influences; conflicting comments regarding levels of confidence and comfort in managing patients

    Obesity is known to be associated with postoperative morbidity in gastric cancer surgery, but its impact on laparoscopy assisted gastrectomy (LAG) for gastric cancer has rarely been evaluated. The clinical data for 1,485 LAG procedures for gastric cancer in 10 institutions were reviewed. The patients were divided into high body mass index (BMI) (BMI > or = 25 kg/m(2); n = 432) and low BMI (BMI gastric cancer. However, when a surgeon is relatively inexperienced with LAG, a careful approach is required for male patients with a high BMI.

    The goal of the point-of-care (POC) sexually transmitted infection (STI) Diagnostics meeting was to review the state-of-the-art research and develop recommendations for the use of POC STI diagnostics. Experts from academia, government, nonprofit, and industry discussed POC diagnostics for STIs such as Chlamydia trachomatis, human papillomavirus, Neisseria gonorrhoeae, Trichomonas vaginalis, and Treponema pallidum. Key objectives included a review of current and emerging technologies, clinical and public health benefits, POC STI diagnostics in developing countries, regulatory considerations, and future areas of development. Key points of the meeting are as follows: (i) although some rapid point-of-care tests are affordable, sensitive, specific, easy to perform, and deliverable to those who need them for select sexually transmitted infections, implementation barriers exist at the device, patient, provider, and health system levels; (ii) further investment in research and development of point-of-care tests for sexually transmitted infections is needed, and new technologies can be used to improve diagnostic testing, test uptake, and treatment; (iii) efficient deployment of self-testing in supervised (ie, pharmacies, clinics, and so on) and/or unsupervised (ie, home, offices, and so on) settings could facilitate more screening and diagnosis that will reduce the burden of sexually transmitted infections; (iv) development of novel diagnostic technologies has outpaced the generation of guidance tools and documents issued by regulatory agencies; and (v) questions regarding quality management are emerging including the mechanism by which poor-performing diagnostics are removed from the market and quality assurance of self-testing is ensured.

    We present a 7-year-old boy with recurrent thrombocytopenia after primary laparoscopic splenectomy for immune thrombocytopenia (ITP). Imaging modalities (ultrasound, computed tomography scan, and scintigraphy) revealed two accessory spleens while the subsequent second laparoscopy revealed 11, which were successfully removed. The relevant medical literature is reviewed, and the value of laparoscopy for chronic ITP is highlighted. PMID:27695216

    We evaluated selection bias in a prospective study of 1,162 consecutive patients with suspected pulmonary embolism. Of these, 983 were eligible, and 627 could actually be included. During two months extensive data were collected on all non-included patients. Finally, our patient characteristics were compared with those of the PIOPED study (1990) and the study of Hull et al. (1994). Compared with included patients, the non-included patients had more often non-diagnostic V/Q scans (50% vs. 36%, p PIOPED study. In the PIOPED study patients who had contra-indications for pulmonary angiography were excluded, while in the study of Hull et al. those with inadequate cardiorespiratory reserve were excluded. In studies on new diagnostic technologies, patient selection bias does occur. The potential for such a selection bias should be taken into account when diagnostic strategies are devised to improve their generalizability and acceptability.

    A major diagnostic intervention in the consideration of many patients suspected to have primary immunodeficiency diseases (PIDDs) is the application and interpretation of vaccination. Specifically, the antibody response to antigenic challenge with vaccines can provide substantive insight into the status of human immune function. There are numerous vaccines that are commonly used in healthy individuals, as well as others that are available for specialized applications. Both can potentially be used to facilitate consideration of PIDD. However, the application of vaccines and interpretation of antibody responses in this context are complex. These rely on consideration of numerous existing specific studies, interpolation of data from healthy populations, current diagnostic guidelines, and expert subspecialist practice. This document represents an attempt of a working group of the American Academy of Allergy, Asthma & Immunology to provide further guidance and synthesis in this use of vaccination for diagnostic purposes in consideration of PIDD, as well as to identify key areas for further research.

    Despite higher costs for robotic-assisted laparoscopy (RAL) than standard laparoscopy (SL), RAL treatment of endometriosis is performed without established indications. PubMed/MEDLINE was searched for 'robotic surgery' and 'endometriosis' or 'gynaecological benign disease' from January 2000 to December 2016. Full-length studies in English reporting original data were considered. Among 178 articles retrieved, 17 were eligible: 11 non-comparative (RAL only) and six comparative (RAL versus SL). Non-comparative studies included 445 patients. Mean operating time, blood loss and hospital stay were 226 min, 168 ml and 4 days. Major complications and laparotomy conversions were 3.1% and 1.3%. Eight studies reported pain improvement at 15-month follow-up. Comparative studies were all retrospective; 749 women underwent RAL and 705 SL. Operating time was longer for RAL in five studies. Major complications and laparotomy conversions for RAL and SL were 1.5% versus 0.3% and 0.3% versus 0.5%. One study reported pain reduction for RAL at 6-month follow-up. RAL treatment of endometriosis did not provide benefits over SL, overall and among subgroups of women with severe endometriosis, peritoneal endometriosis and obesity. Available evidence is low-quality, and data regarding long-term pain relief and pregnancy rates are lacking. RAL treatment of endometriosis should be performed only within controlled studies.

    2015-01-01

    Full Text Available Background: Cutaneous ureterostomy is still practiced despite a trend towards primary surgical correction for obstructive or refluxive uropathy. For future open reimplantation, ureterostomy can be created by minimal invasive technique at the end(s of the suprapubic creaseline. Materials and Methods: From 1 January 2009 to 31 July 2012, seven children were treated with laparoscopy-assisted cutaneous ureterostomy followed by ureteric reimplantation. Indications were primary obstructive megaureter 3, hugely dilated ureters with reflux 3 and posterior urethral valve with poor general health 1. The distal manoeuverable part of tortuous ureter was pulled to the surface at either end of suprapubic creaseline to create the stoma. During reimplantation, this stoma was dismembered and brought inside urinary bladder obviating the need for stoma-site repair. Results: Mean age was 4.6 ± 2.8 years with six males. There were three bilateral cases with total 10 lesions. Mean operating time was 39.8 ± 12.5 minutes. Mean follow-up was 1.7 ± 0.8 years and except for peri-stomal excoriations no major complication occurred. All these were reimplanted 6-12 months after ureterostomy and faring well except in one case. Conclusions: Laparoscopy-assisted cutaneous ureterostomy can be fashioned at suprapubic creaseline to facilitate future reimplantation without much jeopardy and extra scar.

    Over the past three decades, rates of overweight and obesity internationally have risen to epidemic proportions. There are currently no published prospective studies examining the effect of obesity on gynaecologic laparoscopy for benign indications within a population with obesity rates comparable to Australian women. To assess and quantify whether increasing patient body mass index negatively impacted upon the ability to successfully complete planned laparoscopic surgery. From January 2009 until October 2012, 307 women undergoing laparoscopic gynaecological surgery for benign pathology were recruited. Intra-operative variables included the following: ease of identification of anatomical landmarks, entry technique and number of attempts, conversion to laparotomy and any complications encountered. Any post-operative complications were recorded at the six week post-operative review. 94.46% of operations were completed as planned. As BMI increased, the ease of identification of important anatomical landmarks significantly decreased. There was no correlation between increasing BMI and surgical complication rates. Planned gynaecological laparoscopy can be performed in obese patients with a high likelihood of completion. In this study, obesity was not associated with a significant increase in complication rates or failure to complete the surgery as planned. © 2014 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    Hoffmann, S; Abele, H; Bachmann, C

    2016-04-01

    Objective: Bilateral tubal ectopic pregnancies are rare; the reported incidence is only 1 in 200 000 pregnancies. Detecting bilateral tubal ectopic pregnancy is urgent because of the associated morbidity and mortality. The appropriate fertility-preserving surgery must also be considered, as preservation of both tubes is presumed to offer better fertility prospects. Case Report: A 39-year-old gravida 2, para 1 presented with vaginal bleeding at 8 + 4 weeks of gestation. An approximately 18 mm adnexal mass in the right fallopian tube was detected on ultrasound. Laparoscopy was performed because ectopic pregnancy was suspected. This suspicion was confirmed during laparoscopy; the right fallopian tube was found to contain a mass measuring 20 mm in the isthmic part. Ultrasound of the left fallopian tube also showed a mass in the ampullary region (diameter: 10 mm), also suspicious for ectopic pregnancy. Bilateral salpingotomy was performed laparoscopically. Pathological examination confirmed the diagnosis. Conclusions for Practice: Although ectopic tubal pregnancy is seen more often after assisted reproductive techniques, bilateral spontaneous ectopic pregnancies must also be considered in other cases. Laparoscopic surgery is effective to confirm the diagnosis and treat heterotopic pregnancies. Further studies will be needed to confirm whether unilateral or bilateral conservative fertility-preserving surgery is more appropriate.

    In gastric cancer patients, the most common form of synchronous cancer is colorectal cancer. To reduce the invasiveness of the resection, a laparoscopy-assisted combined resection was performed in three patients with synchronous gastric and colorectal cancer. Although all gastric lesions were in the early stages, two colorectal lesions were advanced cases. In all cases, the laparoscopic gastric resection and reconstruction was performed first, followed by the colorectal resection. In the case of right-side colon cancer in addition to gastric cancer, it was relatively easy to perform the combined resection with lymph node dissection sharing the same ports used for the gastrectomy, although we needed an additional port. In one case, in which rectal cancer was present in addition to gastric cancer located in the upper portion of the stomach, a totally laparoscopic proximal gastrectomy was combined with a laparoscopy-assisted low anterior resection, leaving only a lower abdominal minilaparotomy wound. All patients quickly returned to normal activity without remarkable complications, with the exception of a wound infection in one patient. With a mean follow-up of 30.7 months, all patients survived without any sign of recurrence. This procedure represents a feasible option for minimally invasive treatment of synchronous gastric and colorectal cancer.

    Full Text Available Introduction. Congenital pelviureteric junction obstruction (PUJO is one of the most common causes of hydronephrosis. Historically, open dismembered pyeloplasty has been considered the gold standard intervention for correcting PUJO. The aim of this study was to compare the surgical and functional outcomes of three different approaches, namely, open, conventional laparoscopy, and robotic pyeloplasty. Material and Methods. 60 patients underwent minimally invasive pyeloplasty (30 conventional laparoscopies and 30 robotics for congenital PUJO at a tertiary health center in India. Demographic, perioperative, and postoperative data were prospectively collected and analyzed. The data of these patients were retrospectively compared with another cohort of 30 patients who had undergone open pyeloplasty. Results. There was significant difference in operative time, time to drain removal, hospital stay, pain score, and complications rate between open and minimally invasive pyeloplasty (P<0.05. SFI was considerably lesser in robotic as compared to conventional laparoscopy. The success rate in OP, CLP, and RP was 93.33, 96.67, and 96.67%. Conclusion. Robotic pyeloplasty is safe, effective, and feasible. It is associated with significantly lesser operative time, lesser blood loss, less pain, shorter hospital stay, and fewer complications. It is also associated with considerably lesser surgeon fatigue as compared to conventional laparoscopy pyeloplasty.

    Bossuyt Patrick MM

    2007-08-01

    Full Text Available Abstract Background The acute abdomen is a frequent entity at the Emergency Department (ED, which usually needs rapid and accurate diagnostic work-up. Diagnostic work-up with imaging can consist of plain X-ray, ultrasonography (US, computed tomography (CT and even diagnostic laparoscopy. However, no evidence-based guidelines exist in current literature. The actual diagnostic work-up of a patient with acute abdominal pain presenting to the ED varies greatly between hospitals and physicians. The OPTIMA study was designed to provide the evidence base for constructing an optimal diagnostic imaging guideline for patients with acute abdominal pain at the ED. Methods/design Thousand consecutive patients with abdominal pain > 2 hours and Discussion This study aims to provide the evidence base for the development of a diagnostic algorithm that can act as a guideline for ED physicians to evaluate patients with acute abdominal pain.

    The aim of this study was to compare outcomes between laparoscopy-assisted distal gastrectomy (LADG) and open distal gastrectomy (ODG) in obese and non-obese patients. Subjects comprised 248 consecutive patients who underwent distal gastrectomy for gastric cancer between January 1999 and December 2005. Patients with body mass index (BMI) > or = 25 kg/m2 were defined as obese, and patients with BMI obese. Parameters analyzed included patients characteristics, tumor characteristics, operative details, postoperative outcomes, and prognosis. For LADG, 35 patients were considered obese, and 106 patients were non-obese. For ODG, 25 patients were considered obese, and 82 patients were non-obese. Mean operative times in each procedure were significantly longer for the obese group than for the non-obese group (ODG: 241.4 min vs. 199.5 min, p obese group than for the non-obese group in ODG (300 ml vs. 400 ml, p = 0.024), but no significant differences were observed between obese and non-obese groups for LADG. Incidence of major postoperative complications, number of retrieved lymph nodes, and disease-free survival rates were similar in obese and non-obese groups for each procedure. Our analysis revealed that LADG can be safely performed in obese patients, with complication rates and operation outcomes similar to those for non-obese patients.

    2009-01-01

    Full Text Available Abstract Background Splenosis is a heterotropic implantation of splenic fragments onto exposed vascularised peritoneal and intrathoracic surfaces, following splenic injury or elective splenectomy. Case presentation A 60 year old cirrhotic patient was referred to us with a hepatic mass, suspected to be HCC in a cirrhotic liver. A computerized tomography scan (CT demonstrated a cirrhotic liver with a 2 × 2.7 cm focal hypervascular nodule, lying peripherally at the junction of segment 7 and 8. Diagnostic laparoscopy demonstrated a 3 cm exofitic dark brown splenunculus attached to the diaphragm and indenting the surface of segment 7 of the liver. The lesion was easily resected laparoscopically and shaved from the live surface with no need for a liver resection. The histopathological assessment confirmed the diagnosis of splenunculus, with no evidence of neoplasia. Conclusion Hepatic splenosis is not a rare event and should be suspected in patients with a history of splenic trauma or splenectomy. Correct diagnosis is essential and will determine subsequent management plans. In doubtful cases laparoscopic investigation can offere essential information and should be part of the standard protocol for investigating suspected splenosis.

    Laparoscopic surgery is now an integral technique in the practice of urology, particularly in the management of certain urologic malignancies. Advanced laparoscopy training in urology is primarily reserved for those pursuing fellowship training and is offered both by traditional endourology fellowships and increasingly in urologic oncology fellowships. The purpose of our study was to evaluate and compare current laparoscopy training at the fellowship level. A 17-item questionnaire was developed with support from both the Endourological Society (EUS) and Society of Urologic Oncology (SUO). Surveys were sent to program directors of fellowships recognized by the EUS and SUO. Directors were surveyed on the laparoscopic case volume, degree of oncology training, and career choice of their graduates. Data were analyzed with Wilcoxon rank-sum and Student t tests. Our survey had an overall response rate of 60%. Fellows performed more than 100 laparoscopies during their training period in 57% of EUS and 25% of SUO fellowship programs. Similar trends are demonstrated when analyzing robotic procedures, with 73% of EUS fellows performing more than 50 procedures compared with 43% of SUO fellows. The majority (59%) of EUS programs provide oncologic training. Between 44% and 100% of graduates from EUS and SUO fellowships obtain academic positions. The majority of SUO directors (63%) believe that fellowship training in laparoscopy should be provided in fellowships governed solely by the SUO, while 41% of EUS directors believe this training should be governed solely by the EUS. Endourology fellowships currently provide a greater exposure to laparoscopy and robotics than SUO fellowships. The percentage of fellows seeking academic positions is similar for EUS and SUO fellowship programs and has remained stable for several years. Directors of fellowship programs that offer advanced laparoscopic training have divergent views as to which administrative body should govern its future.

From the cohort of 35 patients having single-port laparoscopy (SPL, a sealed envelope method was used to randomly select ten patients to the TAP group and 25 patients to the control group. The ten patients in the TAP group received ultrasound-guided TAP blocks with 30 mL of 0.2% Ropivacaine injected bilaterally. The dermatomal distribution of the sensory block (by pinprick test was recorded. VAS scores for the first 24 hours after surgery and opioid use were compared between the IV-PCA+TAP block and IV-PCA only groups.Results: Sensory block ranged from T5–L1. Mean VAS pain scores decreased from 8 ± 2 to 4 ± 3 (P=0.04 within 30 minutes of TAP block administration. Compared with patients given IV-PCA only, significantly fewer patients who received TAP block had moderate or severe pain (VAS 4–10 after block administration at 6 hours and 12 hours post-surgery.

    INTRODUCTION: Laparoscopy is well established in the majority of elective procedures in abdominal surgery. In contrast, it is primarily used in minor surgery such as appendectomy or cholecystectomy in the emergent setting. This study aimed to analyze the safety and effectiveness of a laparoscopic...... approach in a large cohort of major abdominal emergencies. METHODS: A population-based cohort from the Region of Copenhagen, Denmark, including n = 1,139 patients undergoing major abdominal emergency surgery in 2012. RESULTS: A total of 313 patients were operated with an initial laparoscopic approach; 37......% were laparoscopically completed and 63% of the operations were converted to a laparotomy. Most conversions (40%) were for performing a bowel resection, 35% were due to inadequate exposure, 2% were converted due to accidental bleeding and 7% due to iatrogenic injuries. The reoperation rate was 17...

    A 56-year-old woman who was found to have a submucosal tumor (SMT) of the stomach in a medical check-up was admitted to our hospital for a detailed investigation of the SMT. Upper gastrointestinal endoscopy revealed an SMT of 20mm at the anterior wall of the antrum of the stomach. Endoscopic ultrasonography showed a hyperechoic tumor in the fourth layer of the stomach wall. CT examination showed a strongly enhancing tumor on arterial phase images and persistent enhancement on portal venous phase images. Laparoscopy endoscopy cooperative surgery was performed with a diagnosis of SMT of the stomach highly suspicious of a glomus tumor. Immunohistochemistry revealed expression of α-SMA but no expression of desmin, c-kit, CD34, or S-100. The tumor was finally diagnosed as a glomus tumor of the stomach.

    Arteriovenous malformations of the stomach are an uncommon cause of upper GI bleeding. We report a case of stomach arteriovenous malformation in an 85-year-old Asian man who presented with massive hematemesis. Initial esophagogastroduodenoscopy did not detect this lesion, but contrast multi-detector CT confirmed GI bleeding. Multi-detector CT revealed a mass of blood vessels underlying the submucosa that arose from the right gastroepiploic artery. Repeat esophagogastroduodenoscopy showed that the lesion was a submucosal tumor with erosion and without active bleeding in the lower body of the stomach on the greater curvature. We performed partial gastrectomy via laparoscopy-assisted surgery. The histopathological diagnosis was arteriovenous malformation. © 2016 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and John Wiley & Sons Australia, Ltd.

    We present a female patient with sigmoid colon endometriosis who was diagnosed correctly preoperatively and underwent minimally invasive surgery. She was admitted to our hospital with rectal bleeding and constipation. We performed several workups. Colonoscopy and endoscopic ultrasonography showed sigmoid colon stenosis caused by submucosal tumor, and magnetic resonance imaging revealed a sigmoid colon tumor displaying signal hypointensity on both T1- and T2-weighted imaging. However, colonoscopic ultrasonography-assisted needle aspiration biopsy could not specify tumor characteristics. From these examinations, the lesion was diagnosed as sigmoid colon endometriosis and laparoscopy-assisted sigmoidectomy was performed. Pathological diagnosis from the resected specimen was identical to preoperative diagnosis, i.e., colonic endometriosis. Since differential diagnosis of intestinal endometriosis seems difficult, a cautious preoperative diagnosis is required to select treatments including minimally invasive surgery.

    Gastric carcinoma is derived from epithelial cells inthe gastric mucosa. We reported an extremely rarecase of submucosal gastric carcinoma originating fromthe heterotopic submucosal gastric gland (HSG) thatwas safely diagnosed by laparoscopy and endoscopycooperative surgery (LECS). A 66-year-old manunderwent gastrointestinal endoscopy, which detected asubmucosal tumor (SMT) of 1.5 cm in diameter on thelesser-anterior wall of the upper gastric body. The tumorcould not be diagnosed histologically, even by endoscopicultrasound-guided fine-needle aspiration biopsy. Localresection by LECS was performed to confirm a diagnosis.Pathologically, the tumor was an intra-submucosal welldifferentiated adenocarcinoma invading 5000 μm into the submucosal layer. The resected tumor had negativelateral and vertical margins. Based on the Japanesetreatment guidelines, additional laparoscopic proximalgastrectomy was curatively performed. LECS is a lessinvasive and safer approach for the diagnosis of SMT,even in submucosal gastric carcinoma originating fromthe HSG.

    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.

    BACKGROUND: The systemic impact of intra-abdominal pressure (IAP) and/or changes in carbon dioxide (CO2) during laparoscopy are not yet well defined. Changes in brain oxygenation have been reported as a possible cause of cerebral hypotension and perfusion. The side effects of anaesthesia could also be involved in these changes, especially in children. To date, no data have been reported on brain oxygenation during routine laparoscopy in paediatric patients. PATIENTS AND METHODS: Brain and peripheral oxygenation were investigated in 10 children (8 male, 2 female) who underwent elective minimally invasive surgery for inguinal hernia repair. Intraoperative transcranial near-infrared spectroscopy to assess regional cerebral oxygen saturation (rScO2), peripheral oxygen saturation using pulse oximetry and heart rate (HR) were monitored at five surgical intervals: Induction of anaesthesia (baseline T1); before CO2 insufflation induced pneumoperitoneum (PP) (T2); CO2 PP insufflation (T3); cessation of CO2 PP (T4); before extubation (T5). RESULTS: rScO2 decreases were recorded immediately after T1 and became significant after insufflation (P = 0.006; rScO2 decreased 3.6 ± 0.38%); restoration of rScO2 was achieved after PP cessation (P = 0.007). The changes in rScO2 were primarily due to IAP increases (P = 0.06). The HR changes were correlated to PP pressure (P < 0.001) and CO2 flow rate (P = 0.001). No significant peripheral effects were noted. CONCLUSIONS: The increase in IAP is a critical determinant in cerebral oxygenation stability during laparoscopic procedures. However, the impact of anaesthesia on adaptive changes should not be underestimated. Close monitoring and close collaboration between the members of the multidisciplinary paediatric team are essential to guarantee the patient's safety during minimally invasive surgical procedures.

    Hepar lobatum carcinomatosum (HLC) is defined as an acquired hepatic deformity consisting of an irregularly lobulated hepatic contour caused by intravascular infiltration of metastatic carcinoma. To date, only nine cases of HLC have been reported in the literature. We report a case of a 68-year-old woman showing hepatic metastasis of breast carcinoma in radiologically unidentified form. Initially, she received left partial mastectomy for breast cancer but solid hepatic metastases were identified in S2 and S6, 9 mo after surgery. Then, they responded to chemotherapy and radiologically disappeared. After radiological disappearance of the liver tumors, the patient's blood chemistry showed abnormal liver function. A CT scan demonstrated heterogeneous enhancement effect in the liver in the late phase,suggesting uneven hepatic blood supply. Hepatic deformity was not obvious. Laparoscopy revealed a slightly deformed liver surface with multiple indentations and shallow linear depressions. Furthermore, a wide scar was observed on the surface of S2 possibly at the site where the metastatic tumor existed before chemotherapy. Liver biopsy from the wide scar lesion showed intraportal tumor thrombi with desmoplastic change. Because of its similarity to the histology of the original breast cancer, we concluded that the hepatic functional abnormalities and slightly deformed liver surface were derived from the circulatory disturbance caused by microscopic tumor thrombi. Besides, since the wide scar was located at the site of the pre-existing tumor,it is probable that chemotherapy was an important cause of fibrous scarring as a result of tumor regression. These morphologic findings are compatible with those of HLC.Laparoscopy-assisted liver biopsy was useful to make definite diagnosis, even though the hepatic deformity was radiologically undetectable.

    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

    Low back and radicular pain recently became a major public health problem. Medical expenses in general, and surgical procedures associated with overall care for the lower back pain are high and growing. Furthermore, these two chronic pain conditions are also leading causes for missed workdays. Degenerative changes of the intervertebral disc, facet joints, sacroiliac joint or disc herniation as described during imaging diagnostics may or may not be the cause of patients' lower back pain. Diagnostic blocks often precede further interventions in order to confirm or dispute a source of the lower back pain. Chronic lower back pain caused by painful intervertebral disc should be treated using biacuplasty. If the pain of the lumbar spine is caused by facet joints or sacroiliac joint, patient can be offered neuroablative procedures using radiofrequency. In cases where the low back and radicular pain are caused by the central and foraminal spinal stenosis patients are advised epidural steroid injections, unless claudications are present. Patients suffering from the chronic radicular pain may be treated with various nucleoplasty procedures or they may be offered percutaneous radiofrequent neuromodulation. The purpose of above advised procedures is to relieve patients' pain, allow optimal physical therapy, and improved functional capacity, consequently providing better quality of life.

    Augmentation of symptom severity is the main complication of dopaminergic treatment of restless legs syndrome (RLS). The current article reports on the considerations of augmentation that were made during a European Restless Legs Syndrome Study Group (EURLSSG)-sponsored Consensus Conference in April 2006 at the Max Planck Institute (MPI) in Munich, Germany, the conclusions of which were endorsed by the International RLS Study Group (IRLSSG) and the World Association of Sleep Medicine (WASM). The Consensus Conference sought to develop a better understanding of augmentation and generate a better operational definition for its clinical identification. Current concepts of the pathophysiology, clinical features, and therapy of RLS augmentation were evaluated by subgroups who presented a summary of their findings for general consideration and discussion. Recent data indicating sensitivity and specificity of augmentation features for identification of augmentation were also evaluated. The diagnostic criteria of augmentation developed at the National Institutes of Health (NIH) conference in 2002 were reviewed in light of current data and theoretical understanding of augmentation. The diagnostic value and criteria for each of the accepted features of augmentation were considered by the group. A consensus was then developed for a revised statement of the diagnostic criteria for augmentation. Five major diagnostic features of augmentation were identified: usual time of RLS symptom onset each day, number of body parts with RLS symptoms, latency to symptoms at rest, severity of the symptoms when they occur, and effects of dopaminergic medication on symptoms. The quantitative data available relating the time of RLS onset and the presence of other features indicated optimal augmentation criteria of either a 4-h advance in usual starting time for RLS symptoms or a combination of the occurrence of other features. A paradoxical response to changes in medication dose also indicates

    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.

    The authors are grateful for the interesting perspectives given by Buchs and colleagues in their letter to the editor entitled "3D Laparoscopy: A Step Toward Advanced Surgical Navigation." Shutter-based 3D video systems failed to become established in the operating room in the late 1990s. To strengthen the starting conditions of the new 3D technology using better monitors and high definition, the authors give suggestions for its practical use in the clinical routine. But first they list the characteristics of single-channeled and bichanneled 3D laparoscopes and describe stereoscopic terms such as "comfort zone," "stereoscopic window," and "near-point distance." The authors believe it would be helpful to have the 3D pioneers assemble and share their experiences with these suggestions. Although this letter discusses "laparoscopy," it would also be interesting to collect experiences from other surgical disciplines, especially when one is considering whether to opt for bi- or single-channeled optics.

    Laparoscopic resection of rectal cancer or gastric cancer has been advocated for the benefits of a reduced morbidity, a shorter treatment time, and similar outcomes. However, simultaneous laparoscopy-assisted low anterior resection and distal gastrectomy for synchronous carcinoma of rectum and stomach are rarely documented in literature. Endoscopic examination revealed a synchronous carcinoma of rectum and stomach in a 55-year-old male patient with rectal bleeding and epigastric discomfort. He underwent a simultaneous laparoscopy-assisted low anterior resection and distal gastrectomy with regional lymph nodes dissected. The operation time was 270 min and the estimated blood loss was 120 mL. The patient required parenteral analgesia for less than 24 h. Flatus was passed on postoperative day 3, and a solid diet was resumed on postoperative day 7. He was discharged on postoperative day 13. With the advances in laparoscopic technology and experience, simultaneous resection is an attractive alternative to a synchronous gastrointestinal cancer.

    Mild cognitive impairment (MCI) was proposed as a nosological entity referring to elderly people with mild cognitive deficit but no dementia. MCI is a heterogeneous clinical entity with multiple sources of heterogeneity. The concept of MCI was reviewed and a diagnostic procedure with three different stages was proposed by the European Consortium on Alzheimer's Disease Working Group on MCI. Firstly, MCI should correspond to cognitive complaints coming from the patients or their families; the reporting of a relative decline in cognitive functioning during the past year by a patient or informant; cognitive disorders as evidenced by clinical evaluation; absence of major repercussions on daily life; and absence of dementia. These criteria, similar to those defined during an international workshop in Stockholm, make it possible to identify an MCI syndrome, which is the first stage of the diagnostic procedure. Secondly, subtypes of MCI had to be recognised. Finally, the aetiopathogenic subtype could be identified. Identifying patients at a high risk for progression to dementia and establishing more specific and adapted therapeutic strategies at an early stage, together with more structured overall management, is made possible by the diagnostic procedure proposed.

    The EU directive on medical exposure, 97/43/EURATOM (referred to in the following as MED) imposes new requirements on hospital departments using ionising radiation for either diagnostics or treatment of illnesses. The directive was approved on 30 June 1997, and the member states were obliged to implement the requirements into national legislation before 13 May 2000. The implementation of a directive of this kind is a complicated process requiring time as well as other resources. The Nordic EU countries (Sweden, Finland and Denmark) must comply with the rules in MED, while this is not the case for Norway and Iceland as EFTA (European Free Trade Association) members, since the agreements between EFTA and EU does not cover the EURATOM treaty. The issues that have to be addressed in the national legislation are justification, optimisation, responsibilities, procedures, training, equipment, special protection during pregnancy and breast-feeding, and potential exposure. A central aspect in MED is the requirement for quality assurance programmes to be established in radiological departments (and in other departments employing ionising radiation). A change of this magnitude in legislation requires adjustments in the routines of the individual departments. The staff in each department needs to prepare and follow procedures and instructions for daily work and also participate in day-to-day quality assurance. A considerable burden has also been laid on the radiation protection authorities in the member states, first in the process of transposing MED into national law or regulations, and secondly in guiding the process of practical implementation. Here we will describe how the individual Nordic EU countries have chosen to implement MED in national legislation and how far the process of complying with the requirements has come so far. Although Norway and Iceland are not required to follow MED, it is still interesting for comparison to include the situation in these countries

    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 robot was 157.1 and 342.5 s for 3D with a P value robotic systems over 3D straight-stick laparoscopy, in terms of reduced error rate and quicker task performance time.

    The refinement of surgical techniques represents a key opportunity to improve the welfare of laboratory rodents, while meeting legal and ethical obligations. Current methods used for monitoring intra-abdominal disease progression in rodents usually involve euthanasia at various time-points for end of study, one-time individual tissue collections. Most rodent organ tumour models are developed by the introduction of tumour cells via laparotomy or via ultrasound-guided indirect visualization. Ischaemic rodent models are often generated using laparotomies. This approach requires a high number of rodents, and in some instances introduces high degrees of morbidity and mortality, thereby increasing study variability and expense. Most importantly, most laparotomies do not promote the highest level of rodent welfare. Recent improvements in laparoscopic equipment and techniques have enabled the adaptation of laparoscopy for rodent procedures. Laparoscopy, which is considered the gold standard for many human abdominal procedures, allows for serial biopsy collections from the same animal, results in decreased pain and tissue trauma as well as quicker postsurgical recovery, and preserves immune function in comparison to the same procedures performed by laparotomy. Laparoscopy improves rodent welfare, decreases inter-animal variability, thereby reducing the number of required animals, allows for the replacement of larger species, decreases expense and improves data yield. This review article compares rodent laparotomy and laparoscopic surgical methods, and describes the utilization of laparoscopy for the development of cancer models and assessment of disease progression to improve data collection and animal welfare. In addition, currently available rodent laparoscopic equipment and instrumentation are presented.

    A prospective multicenter trial has been started in Korea to evaluate the diagnostic accuracy of endometrial aspiration biopsy compared with dilatation and curettage in patients treated with progestin for endometrial hyperplasia. For conservative treatment of endometrial hyperplasia, orally administered progestins are most commonly used method with various treatment regimens and more recently, the levonorgestrel-releasing intrauterine system also has been used successfully to treat endometrial hyperplasia. However, there is no report about the accuracy of endometrial sampling during hormonal treatment for follow-up evaluation of endometrial hyperplasia. Patients with histologically confirmed endometrial hyperplasia are offered hormonal treatment with any one of the following three options: oral medroxyprogesterone acetate 10 mg/day for 14 days per cycle, continuous oral medroxyprogesterone acetate 10 mg/day or insertion of levonorgestrel-releasing intrauterine system. Histological surveillance is performed at 3 months or 6 months following initial treatment. Endometrial tissues are obtained via endometrial aspiration biopsy using a pipelle and dilatation and curettage. In the case of levonorgestrel-releasing intrauterine system, endometrial aspiration biopsy will be done with levonorgestrel-releasing intrauterine system in uterus and then, after the removal of levonorgestrel-releasing intrauterine system, dilatation and curettage will be done. The biopsy findings will be compared. The primary endpoint is to compare the pathological outcome of endometrial aspiration with dilatation and curettage. The secondary endpoint is the response rate with three types of progestin treatment at 6 months.

    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

    Because so many common surgical problems can now be addressed by the laparoscopic approach, the issue of sterile processing has to be reconsidered. Selected laparoscopic instrumentation was analyzed regarding wear and tear and decontamination after sterile processing following 6,000 surgical laparoscopies carried out between 1990 and 1996 at the Academic Hospital Moabit, Berlin. Fewer than 7.9 (parts of) instruments failed per 100 laparoscopies. Most of the repairs involved scissors. The main problems were blunting, burnt or disconnected electromechanical components, defective insulation, and damaged or lost parts of dismantable instruments. Residues of human blood proteins were detected on a few instruments. The effect of intraluminal rinsing was documented by measuring the iron content (as an indicator for blood contamination). A comparison of costs showed that it was >10 times cheaper to use instrumentation with reusable components. The sterile processing of economic reusable instrumentation for laparoscopies needs staff well trained in sterile supply. Instrument design should allow easy dismantling and rinsing of internal parts. Insulating compounds present a problem for decontamination. Disinfection with aldehydes before cleaning the lumina of instruments must be avoided because protein coagulation will occur. A tube-in-tube concept for tubular instruments offering compatibility should be favored.

    Background Because of the high prevalence of obesity, there is a growing demand for bariatric surgery worldwide. The objective of this systematic review was to analyze the difference in relation to cost-effectiveness of access route by laparoscopy versus laparotomy of Roux en-Y gastric bypass (RYGB). Methods A systematic review was conducted in the electronic databases MEDLINE, Embase, Scopus, Cochrane and Lilacs in order to identify economic evaluation studies that compare the cost-effectiveness of laparoscopic and laparotomic routes in RYGB. Results In a total of 494 articles, only 6 fulfilled the eligibility criteria. All studies were published between 2001 and 2008 in the United States (USA). Three studies fulfilled less than half of the items that evaluated the results quality; two satisfied 5 of the required items, and only 1 study fulfilled 7 of 10 items. The economic evaluation of studies alternated between cost-effectiveness and cost-consequence. Five studies considered the surgery by laparoscopy the dominant strategy, because it showed greater clinical benefit (less probability of post-surgical complications, less hospitalization time) and lower total cost. Conclusion This review indicates that laparoscopy is a safe and well-tolerated technique, despite the costs of surgery being higher when compared with laparotomy. However, the additional costs are compensated by the lower probability of complications after surgery and, consequently, avoiding their costs. PMID:24945704

    In myelodysplastic syndromes (MDS), deletion of the short arm of chromosome 12 (del(12p)) is usually a small abnormality, rarely detected as a single aberration by chromosome banding analysis (CBA) of bone marrow metaphases. Del(12p) has been described in 0.6 to 5% of MDS patients at initial diagnosis and is associated with a good to intermediate prognosis as a sole anomaly according to current scoring systems. Here, we present the results of a systematic del(12p) testing in a German prospective diagnostic study (clinicaltrials.gov: NCT01355913) on 367 MDS patients in whom CD34+ peripheral blood cells were analysed for the presence of del(12p) by sequential fluorescence in situ hybridization (FISH) analyses. A cohort of 2,902 previously published MDS patients diagnosed by CBA served as control. We demonstrate that, using a sensitive FISH technique, 12p deletion occurs significantly more frequently in MDS than previously described (7.6% by CD34+ PB-FISH vs. 1.6% by CBA, P < 0.001) and is often associated with other aberrations (93% by CD34+ PB-FISH vs. 60% by CBA). Additionally, the detection rate can be increased by repeated analyses in a patient over time which is important for the patient´s prognosis to distinguish a sole anomaly from double or complex aberrations. To our knowledge, this is the first study to screen for 12p deletions with a suitable probe for ETV6/TEL in 12p13. Our data suggest that the supplement of a probe for the detection of a 12p deletion to common FISH probe panels helps to avoid missing a del(12p), especially as part of more complex aberrations.

    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.

    Complex laparoscopy is difficult to master because it involves 3-dimensional (3D) interpretation on a 2-dimensional (2D) viewing screen. The use of 3D technology has an uncertain effect on training surgeons. We aim to evaluate the effectiveness of 3D on learning and performing laparoscopic tasks. Medical students without laparoscopic experience (novices) were evaluated doing inanimate object transfer and laparoscopic suturing. Tasks were repeated using 2D and 3D cameras with standard instruments. Time and error rates (missed attempts, dropped objects, and failure to complete the task) were recorded. Twenty-nine novice medical students experienced a 45.5% decrease in the time to complete PEG transfer using 3D (mean 207 s with 2D vs. 113 s with 3D). Error rate was reduced to 50% (2D, 4 errors vs. 3D, 2 errors) and mean drop rate was reduced to 0. Similar decreases in suture time (46.5%) were seen (mean 403 s with 2D vs. 220 s with 3D). Our results indicate that 3D significantly improved visualization and ability to perform complex tasks in the skills laboratory setting. This technology may be very effective in teaching advanced laparoscopic skills in the era of work-hour restrictions.

    This article presents the implementation of surgeon's musculo-skeletal model for gesture analysis in laparoscopy, thereby providing a complete account of the objective metrics needed to evaluate surgical performance and to improve the design of new surgical instruments including robotic instrumentation for surgical procedures. Previous published work has been based exclusively on the kinematics involved whereas, this study is focused on the dynamics and muscle contraction analysis to assess loads on bones and muscle fatigue during simulation of surgical interventions. Nine medical students and 2 fully trained surgeons participated in the experimental sessions using a virtual laparoscopic simulator. Movement was acquired by means of an Optical Localization System and processed by means of the biomechanical software platform ADAMS-LifeMOD. The musculo-skeletal analysis allows calculation of how the muscles are used and their respective mean work during the exercises. Results, relative to biceps and trapezius for left and right arm, clearly demonstrate different proficiencies between surgeons and medical students and highlight differences in using different surgical instruments and assumption of different postures. The model provides data on the evaluation of biomechanical parameters of surgical gesture not only in kinematic terms but also includes analysis of the dynamics of muscle contraction analysis during surgical manipulations.

    The number of obese and morbidly obese patients within the developed world is dramatically increasing within the last 20 years. Apart from demographical changes, obese patients are especially prone to have oestrogen-dependent morbidities and neoplasias, of which laparoscopic treatment should be the standard of care. The increasing number of patients with BMI >40 is concerning, making it necessary to summarise considerations for safe and effective Gynaecological Laparoscopic Surgery. The sequel to successful laparoscopic surgery in obese patients comprises an interdisciplinary appreciation of laparoscopy. Preoperatively, anaesthetics and medical review are suggested to optimise treatment of comorbidities (i.e. infections and blood sugar levels). Positioning of the patient should consider anti-slip options and pannus fixation to ease laparoscopic access and decrease pressure to the chest. There is no standard port placement in obese patients and landmarks have to be the bony structures of the pelvis and ribs. Retraction of the bowel is essential and mobilisation of the sigmoid with fan retractors or endoloops can accomplish adequate vision. 30° scopes can be considered for vision "around the obstacle". An experienced assistant with anticipation of surgical steps is favourable for successful surgery completion. Intra-operatively, good surgical techniques are essential. Vessel sealing systems reduce the need for instrument changes and may be helpful in following visualised tissue planes. A transvaginal vault closure may be advantageous compared to laparoscopic closure and Endostiches may be preferred to close the fascia of large trocar sites under vision.

    Clinical diagnostics in metabolic bone diseases cover a broad spectrum of conventional and state of the art methods ranging from the medical history and clinical examination to molecular imaging. Patient treatment is carried out in an interdisciplinary team due to the multiple interactions of bone with other organ systems. Diagnosis of osteoporosis is supported by high level national guidelines. A paradigm shift concerning the clinical relevance of bone mineral density measurement renders this now to be a strong risk factor rather than a diagnostic parameter, while strengthening the value of other clinical factors for risk assessment. The impact of parameters for muscle mass, structure and function is steadily increasing in all age groups. In order to identify underlying diseases that influence bone metabolism a panel of general laboratory diagnostic parameters is recommended. Markers for bone formation and resorption and specific parameters for the regulation of calcium and phosphate metabolism should be evaluated by specialists because they require diligence in preanalytics and experience in interpretation. Genetic diagnosis is well established for rare bone diseases while diagnostic panels are not yet available for routine diagnostics in polygenetic diseases such as osteoporosis. Conventional radiology is still very important to identify, e. g. fractures, osteolytic and osteoblastic lesions and extraosseous calcifications; however tomography-based methods which combine, e. g. scintigraphy or positron emission technologies with anatomical imaging are of increasing significance. Clinical diagnostics in osteology require profound knowledge and are subject to a dynamic evolution.

    Various methods exist to detect an astrovirus infection. Current methods include electron microscopy (EM), cell culture, immunoassays, polymerase chain reaction (PCR) and various other molecular approaches that can be applied in the context of diagnostic or in surveillance studies. With the advent of metagenomics, novel human astrovirus (HAstV) strains have been found in immunocompromised individuals in association with central nervous system (CNS) infections. This work reviews the past and current methods for astrovirus detection and their uses in both research laboratories and for medical diagnostic purposes. PMID:28085120

    This study assessed the overall and specific prevalence of the main rheumatic regional pain syndromes (RRPS) in four Latin-American indigenous groups. A Community Oriented Program for Control of Rheumatic Diseases (COPCORD) methodology-based census study was performed in 4240 adults (participation rate: 78.88 %) in four indigenous groups: Chontal (Oaxaca, Mexico, n = 124), Mixteco (Oaxaca, Mexico; n = 937), Maya-Yucateco (Yucatán, Mexico; n = 1523), and Qom (Rosario, Argentina; n = 1656). Subjects with musculoskeletal pain were identified using a cross-cultural, validated COPCORD questionnaire administered by bilingual personnel, and reviewed by general practitioners or rheumatologists using standardized case definitions for the 12 most frequent RRPS. The overall prevalence of RRPS was confirmed in 239 cases (5.64 %, 95 % CI: 4.98-6.37). The prevalence in each group was Chontal n = 19 (15.32 %, 95 % CI: 10.03-22.69); Maya-Yucateco n = 165 (10.83 %, 95 % CI: 9.37-12.49); Qom n = 48 (2.90 %, 95 % CI: 2.19-3.82); and Mixteco n = 7 (0.75 %, 95 % CI: 0.36-1.53). In the whole sample, the syndrome-specific prevalence was rotator cuff tendinopathy: 1.98 % (95 % CI: 1.60-2.45); lateral epicondylalgia: 0.83 % (95 % CI: 0.59-1.15); medial epicondylalgia: 0.73 % (95 % CI: 0.52-1.04); biceps tendinopathy: 0.71 % (95 % CI: 0.50-1.01); anserine syndrome: 0.64 % (95 % CI: 0.44-0.92); inferior heel pain: 0.61 % (95 % CI: 0.42-0.90); trochanteric syndrome: 0.49 % (95 % CI: 0.25-0.64); de Quervain's tendinopathy: 0.45 % (95 % CI: 0.29-0.70); trigger finger: 0.42 % (95 % CI: 0.27-0.67); carpal tunnel syndrome: 0.28 % (95 % CI: 0.16-0.49); Achilles tendinopathy (insertional): 0.12 % (95 % CI: 0.05-0.28); and Achilles tendinopathy (non-insertional): 0.07 % (95 % CI: 0.02-0.21).

    Objectives: We sought to define the role of laparoscopy in identifying the clinical significance, cause, and association between adhesions and chronic pelvic pain. Methods: A retrospective chart review was conducted from October 2004 to July 2005, at the Kiel School of Gynecological Endoscopy, University Hospitals Schleswig-Holstein, Campus Kiel, Germany. Included in the study was the analysis of 462 laparoscopic procedures; 275 (59.5%) of the patients undergoing these procedures had pelvic or abdominal adhesions. Of these, 84 (30.5%) patients were admitted with the main complaint of chronic pelvic pain. Further evaluation and assessment of this group was carried out. Results: Among those patients with adhesions, the second most frequent reason for admission was chronic pelvic pain (30.5%) (P<0.0005). In our study, adhesions were found in 79.2% (n=84) of patients (n=106) with chronic pelvic pain. These adhesions were thin- filmy (19.0%) or thick-fibrous (81.0%) adhesions containing blood vessels. Thick-fibrous adhesions were present in 50.0% of patients at multiple abdominopelvic sites (P<0.005). Conclusions: Thick-fibrous adhesions that extend beyond the pelvic sidewall can cause significant chronic abdominopelvic pain. PMID:17931511

    Molecular diagnostic methods and biological imaging techniques can make a major contribution to tailoring patients' treatment needs with regard to medical, ethical and pharmaco-economic aspects. Modern diagnostic methods are already being used to help identify different sub-groups of patients with thoracic tumours who are most likely to benefit significantly from a particular type of treatment. This contribution looks at the most recent developments that have been made in the field of thoracic tumour diagnosis and analyses the pros and cons of new molecular and other imaging techniques in day-to-day clinical practice.

    Klatskin tumors are defined as malignant tumors of the bile duct involving the bifurcation and intrahepatic bile ducts. The most common presenting clinical feature, obstructive jaundice, usually occurs with advanced disease. Diagnostic tools currently available are therefore either performed too late or are not able to detect early disease stage. Imaging procedures for diagnosis and staging are ultrasonography, magnetic resonance imaging with cholangiopancreaticography, intravenous bolus-enhanced spiral computed tomography and endoscopic retrograde cholangiopancreaticography. Before initiating any palliative measure, a proper staging and a surgical consultation at a hepatobiliary center is necessary. To assess resectability, additional diagnostic methods like angiography, positron emission tomography, cholangioscopy, endoscopic or intraluminal ultrasonography and finally even explorative laparoscopy may be required. At time of diagnosis only a small percentage of Klatskin tumors is curative resectable. Therefore, palliative treatment options play an important role. Endoprostheses insertion is the method of choice to relieve jaundice. Although it improves quality of life, it does not seem to improve survival time. Definitive evidence for a benefit of additional radio and/or chemotherapy is still missing. Photodynamic therapy, a light therapy, is the first approach leading to an improvement of cholestasis and quality of life as well as to a prolongation of survival time. PDT should therefore be offered to all patients with nonresectable cholangiocarcinoma.

    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).

    (1) How does the quality of life of patients with ADHD treated in an ambulatory care setting compare to that of other patient groups in child and adolescent psychiatry? (2) Can differences in the quality of life be demonstrated between patients with simple disorders of activity and attention and those with hyperkinetic conduct disorders? (3) How does the quality of life in these patient groups change over one year of treatment? The Inventory for the Assessment of Life Quality in Children and Adolescents (Inventar zur Untersuchung der Lebensqualität von Kindern und Jugendlichen, ILK) was applied to a sample of 726 patients derived from nine different outpatient practices for child and adolescent psychiatry. Among them were 196 patients with a simple disorder of activity and attention and 64 with a hyperkinetic conduct disorder. A comparison between these two groups was the main aim of the study. The mean age of the patients in the sample (all diagnoses) was 8.7 ± 3 years. The two groups of hyperkinetic patients made up 35% of the overall sample, and both of them showed a marked male predominance. The hyperkinetic patients tended to have lower quality-of-life scores than patients in the other diagnostic groups. Longitudinal observation revealed improvements in the quality of life across all patient groups, but the patients with hyperkinetic disorders (both groups) improved the least. The parents of the hyperkinetic patients, too, reported suffering greater stress because of their children's condition than the parents of children with other types of disorders. The ILK instrument has test-metrical qualities that render it usable and capable of holding its own among other, comparable instruments. It can be used to assess the quality of life of children with various diagnoses. Children with ADHD tend to have the least favorable quality-of-life scores, yet they do show some degree of improvement in their quality of life after a year of treatment.

    Full Text Available Background/Aim. Global budget per calendar year is a traditional method of funding hospitals in Serbia. Diagnose related groups (DGR is a method of hospital payment based on classification of patients into groups with clinically similar problems and similar utilization of hospital resources. The aim of this study was to compare current methods of hospital services payment with the projected costs by DRG payment method in urology. Methods. The data were obtained from the information system used in the Clinical Hospital Center “Dr. Dragiša Mišović” - Dedinje in Belgrade, Serbia. The implemented hospital information system was the main criterion for selection of healthcare institutions. The study included 994 randomly selected patients treated surgically and conservatively in 2012. Results. Average costs under the current payment method were slightly higher than those projected by DRG, however, the variability was twice as high (54,111 ± 69,789 compared to 53,434 ± 32,509, p < 0,001 respectively. The univariate analysis showed that the highest correlation with the current payment method as well as with the projected one by DRG was observed in relation to the number of days of hospitalization (ρ = 0.842, p < 0.001, and ρ = 0.637, p < 0.001, respectively. Multivariate regression models confirmed the influence of the number of hospitalization days to costs under the current payment system (β = 0.843, p < 0.001 as well as under the projected DRG payment system (β = 0.737, p < 0.001. The same predictor was crucial for the difference in the current payment method and the projected DRG payment methods (β = 0.501, p <0.001. Conclusion. Payment under the DRG system is administratively more complex because it requires detailed and standardized coding of diagnoses and procedures, as well as the information on the average consumption of resources (costs per DRG. Given that aggregate costs of treatment under two hospital payment methods compared

    Recognition of the significance of anxiety disorders in older adults is growing. The revision of the Diagnostic and Statistical Manual of Mental Disorders (DSM) provides a timely opportunity to consider potential improvements to diagnostic criteria for psychiatric disorders for use with older people. The authors of this paper comprise the Advisory Committee to the DSM5 Lifespan Disorders Work Group, the purpose of which was to generate informative responses from individuals with clinical and research expertise in the field of late-life anxiety disorders. This paper reviews the unique features of anxiety in later life and synthesizes the work of the Advisory Committee. Suggestions are offered for refining our understanding of the effects of aging on anxiety and other disorders (e.g., mood disorders) and changes to the DSM5 criteria and text that could facilitate more accurate recognition and diagnosis of anxiety disorders in older adults. Several of the recommendations are not limited to the study of anxiety but rather are applicable across the broader field of geriatric mental health. DSM5 should provide guidelines for the thorough assessment of avoidance, excessiveness, and comorbid conditions (e.g., depression, medical illness, cognitive impairment) in anxious older adults.

    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.

    Surgery has traditionally been learned on patients in the operating room, which is time-consuming, can have an impact on the patient outcomes, and is of variable effectiveness. As a result, surgical training models have been developed, which are compared in this systematic review. We searched Pubmed, CENTRAL, and Science Citation index expanded for randomised clinical trials and randomised cross-over studies comparing laparoscopic training models. Studies comparing one model with no training were also included. The reference list of identified trials was searched for further relevant studies. Fifty-eight trials evaluating several training forms and involving 1591 participants were included (four studies with a low risk of bias). Training (virtual reality (VR) or video trainer (VT)) versus no training improves surgical skills in the majority of trials. Both VR and VT are as effective in most studies. VR training is superior to traditional laparoscopic training in the operating room. Outcome results for VR robotic simulations versus robot training show no clear difference in effectiveness for either model. Only one trial included human cadavers and observed better results versus VR for one out of four scores. Contrasting results are observed when robotic technology is compared with manual laparoscopy. VR training and VT training are valid teaching models. Practicing on these models similarly improves surgical skills. A combination of both methods is recommended in a surgical curriculum. VR training is superior to unstructured traditional training in the operating room. The reciprocal effectiveness of the other models to learn surgical skills has not yet been established.

    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.

    ABSTRACT Introduction Endometriosis is a disease with causes still unclear, affecting approximately 15% of women of reproductive age, and in 1%-2% of whom it may involve the urinary tract. The bladder is the organ most frequently affected by endometriosis, observed around 85% of the cases. In such cases, the most effective treatment is partial cystectomy, especially via videolaparoscopy. Study Objective, Design, Size and Duration In order to identify and delimit the extent of the intravesical endometriosis lesion, to determine the resection limits, as well as to perform an optimal reconstruction of the organ aiming for its maximum preservation, we performed a cystoscopy simultaneously with the surgery, employing a modified light-to-light technique in 25 consecutive patients, from September 2006 to May 2012. Setting Study performed at Campinas Medical Center – Campinas – Sao Paulo – Brazil.Participants/materials, setting and methods: Patients aged 27 to 47 (average age: 33.4 years) with deep endometriosis with total bladder involvement were selected for the study. The technique used was conventional laparoscopy with a transvaginal uterine manipulator and simultaneous cystoscopy (the light-to-light technique). A partial videolaparoscopic cystectomy was performed with cystoscopy-assisted vesical reconstruction throughout the entire surgical time. The lesions had an average size of 2.75cm (ranging from 1.5 to 5.5cm). The average surgical time was 137.7 minutes, ranging from 110 to 180 minutes. Main Results Postoperative follow-up time was 32.4 months (12-78 months), with clinical evaluation and a control cystoscopy performed every six months. No relapse was observed during the follow-up period. Conclusions A cystoscopy-assisted partial laparoscopic cystectomy with a modified light-to-light technique is a method that provides adequate identification of the lesion limits, intra or extravesically. It also allows a safe reconstruction of the organ aiming for its

    Single-incision laparoscopic surgery (SILS) has been demonstrated to be a feasible alternative to multiport laparoscopy, but concerns over port-site incisional hernias have not been well addressed. A retrospective study was performed to determine the rate of port-site hernias as well as influencing risk factors for developing this complication. A review of all consecutive patients who underwent SILS over 4 years was conducted using electronic medical records in a multi-specialty integrated healthcare system. Statistical evaluation included descriptive analysis of demographics in addition to bivariate and multivariate analyses of potential risk factors, which were age, gender, BMI, procedure, existing insertion-site hernia, wound infection, tobacco use, steroid use, and diabetes. 787 patients who underwent SILS without conversion to open were reviewed. There were 454 cholecystectomies, 189 appendectomies, 72 colectomies, 21 fundoplications, 15 transabdominal inguinal herniorrhaphies, and 36 other surgeries. Cases included 532 (67.6 %) women, and among all patients mean age was 44.65 (±19.05) years and mean BMI of 28.04 (±6). Of these, 50 (6.35 %) patients were documented as developing port-site incisional hernias by a health care provider or by incidental imaging. Of the risk factors analyzed, insertion-site hernia, age, and BMI were significant. Multivariate analysis indicated that both preexisting hernia and BMI were significant risk factors (p value = 0.00212; p value = 0.0307). Morbidly obese patients had the highest incidence of incisional hernias at 18.18 % (p value = 0.02). When selecting patients for SILS, surgeons should consider the presence of an umbilical hernia, increased age and obesity as risk factors for developing a port-site hernia.

    Laparoscopy-assisted distal gastrectomy (LADG) for stomach cancer is increasingly performed in Japan and Korea. However, the procedure still is considered to be complicated, and the optimal education system for trainees has not been established to date. The authors organized a 1-day professional training course termed the LADG Basic Lab Course for LADG beginners. The participants were required to apply as a team of two surgeons and two operating nurses. The training course consisted of lectures and a live porcine lab emphasizing use of the ultrasonically activated device and the flexible laparoscope as well as team cooperation. The quality and effectiveness of the course were evaluated 6-10 months (mean, 8.2 +/- 2.2 months) after the course using a survey form sent to a representative surgeon of each institution. From May 2007 to July 2008, a total of 80 colleagues (47 surgeons and 33 nurses) from 20 different centers in Japan participated in the training course. These surgeons represented 12.4 +/- 6.2 postgraduate years of education and had performed 2.7 +/- 4.9 LADGs before taking the course. In the follow-up evaluation, 12 institutions (60%) completed the survey forms. The mean operation time was reduced for eight respondents (66.7%). The number of LADGs performed per month increased in 50% of the respondents' institutions. The degree of lymph node dissection in LADG was extended for 66.7% of the respondents. The respondents answered that 100% of the first operators showed improvement in skills, as did 59.5% of the scope operators and 59.5% of the nurses. The training course was an effective means of introducing LADG to each institution. Training courses emphasizing explanations of key devices and teamwork may be effective for the introduction of advanced laparoscopic surgeries.

    Full Text Available ABSTRACT: The occlusion of inguinal ring is the treatment to avoid the inguinal hernia in horses. The aim of this study is evaluate the efficacy of homologous pericardium grafts for internal inguinal ring closure in horses, comparing mechanical or manual laparoscopic suture. Cross over study, using six healthy intact male Mangalarga breed horses aged between 3 and 12 years. Horses were operated under general anesthesia in 25º Trendelenburg position. Five laparoscopic portals were employed. Pericardium grafts measuring 4x5cm were anchored covering the left and right internal inguinal rings using either manual intracorporeal suture or laparoscopic stapler. Horses were followed-up during 11 weeks when were submitted to a laparoscopic control. Surgical time, trans and postoperative complications and effectiveness of internal inguinal closure were evaluated and statistically analyzed. The level of significance was set at 5% P<0.05. The procedures were realized without complications and the mean time required for manual and mechanical suture procedures differed significantly (67.8±15.3 and 14.1±2.1 min respectively; P<0.05. All manually sutured grafts remained in place and partial suture dehiscence with incomplete occlusion of the internal inguinal ring was observed in two stapled grafts. Non-severe complications were observed trans or postoperatively. One synechiae and three omental adhesions were observed by laparoscopic control on day 77, but without clinical relevance in the evaluated period. The use of homologous pericardium grafts was effectiveness to internal inguinal ring closure by laparoscopy. Mechanical suture was faster to perform than manual, but provided less satisfactory results concerning safety of graft fixation.

  17. Cystoscopy-assisted laparoscopy for bladder endometriosis: modified light-to-light technique for bladder preservation

    Directory of Open Access Journals (Sweden)

    Rafael Mamprin Stopiglia

    Full Text Available ABSTRACT Introduction Endometriosis is a disease with causes still unclear, affecting approximately 15% of women of reproductive age, and in 1%-2% of whom it may involve the urinary tract. The bladder is the organ most frequently affected by endometriosis, observed around 85% of the cases. In such cases, the most effective treatment is partial cystectomy, especially via videolaparoscopy. Study Objective, Design, Size and Duration In order to identify and delimit the extent of the intravesical endometriosis lesion, to determine the resection limits, as well as to perform an optimal reconstruction of the organ aiming for its maximum preservation, we performed a cystoscopy simultaneously with the surgery, employing a modified light-to-light technique in 25 consecutive patients, from September 2006 to May 2012. Setting Study performed at Campinas Medical Center – Campinas – Sao Paulo – Brazil.Participants/materials, setting and methods: Patients aged 27 to 47 (average age: 33.4 years with deep endometriosis with total bladder involvement were selected for the study. The technique used was conventional laparoscopy with a transvaginal uterine manipulator and simultaneous cystoscopy (the light-to-light technique. A partial videolaparoscopic cystectomy was performed with cystoscopy-assisted vesical reconstruction throughout the entire surgical time. The lesions had an average size of 2.75cm (ranging from 1.5 to 5.5cm. The average surgical time was 137.7 minutes, ranging from 110 to 180 minutes. Main Results Postoperative follow-up time was 32.4 months (12-78 months, with clinical evaluation and a control cystoscopy performed every six months. No relapse was observed during the follow-up period. Conclusions A cystoscopy-assisted partial laparoscopic cystectomy with a modified light-to-light technique is a method that provides adequate identification of the lesion limits, intra or extravesically. It also allows a safe reconstruction of the organ

    The Minnesota Multiphasic Personality Inventory-2 (MMPI-2) F(p) (Infrequency-Psychopathology) scale was developed to measure overreporting in a manner that was minimally confounded by genuine psychopathology, which was a problem with using the MMPI-2 F (Infrequency) scale among patients with severe mental illness. Although revised versions of both of these scales are included on the MMPI-2-Restructured Form and used in a forensic context, no item-level research has been conducted on their sensitivity to genuine psychopathology among forensic psychiatric inpatients. Therefore, we examined the psychometric properties of the scales in a sample of 438 criminally committed forensic psychiatric inpatients who were adjudicated as not guilty by reason of insanity and had no known incentive to overreport. We found that 20 of the 21 Fp-r items (95.2%) demonstrated endorsement rates ≤ 20%, with 14 of the items (66.7%) endorsed by less than 10% of the sample. Similar findings were observed across genders and across patients with mood and psychotic disorders. The one item endorsed by more than 20% of the sample had a 23.7% overall endorsement rate and significantly different endorsement rates across ethnic groups, with the highest endorsements occurring among Hispanic/Latino (43.3% endorsement rate) patients. Endorsement rates of F-r items were generally higher than for Fp-r items. At the scale level, we also examined correlations with the Restructured Clinical Scales and found that Fp-r demonstrated lower correlations than F-r, indicating that Fp-r is less associated with a broad range of psychopathology. Finally, we found that Fp-r demonstrated slightly higher specificity values than F-r at all T score cutoffs. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

    The Madden-Julian Oscillation (MJO) interacts with, and influences, a wide range of weather and climate phenomena (e.g., monsoons, ENSO, tropical storms, mid-latitude weather), and represents an important, and as yet unexploited, source of predictability at the subseasonal time scale. Despite the important role of the MJO in our climate and weather systems, current global circulation models (GCMs) exhibit considerable shortcomings in representing this phenomenon. These shortcomings have been documented in a number of multi-model comparison studies over the last decade. However, diagnosis of model performance has been challenging, and model progress has been difficult to track, due to the lack of a coherent and standardized set of MJO diagnostics. One of the chief objectives of the US CLIVAR MJO Working Group is the development of observation-based diagnostics for objectively evaluating global model simulations of the MJO in a consistent framework. Motivation for this activity is reviewed, and the intent and justification for a set of diagnostics is provided, along with specification for their calculation, and illustrations of their application. The diagnostics range from relatively simple analyses of variance and correlation, to more sophisticated space-time spectral and empirical orthogonal function analyses. These diagnostic techniques are used to detect MJO signals, to construct composite life-cycles, to identify associations of MJO activity with the mean state, and to describe interannual variability of the MJO.

    Diagnosis of pelvic inflammatory disease is difficult. We focus on a systematic literature review to study diagnostic values of history-taking, clinical examination, laboratory tests and imagery. After this literature review, we build a diagnostic model for pelvic inflammatory disease. This diagnostic model is built on two major criteria: presence of adnexal tenderness or cervical motion tenderness. Additional minor criteria, increasing the likelihood of the diagnosis of pelvic inflammatory disease were added based on their specificity and their positive likelihood ratio. These minor criteria are supported by history-taking, clinical examination, laboratory tests and also on relevant ultrasonographic criteria. Copyright © 2012 Elsevier Masson SAS.

    Minimally invasive hysterectomy in obese patients may be limited by laparoscopic sight on the one hand and by intraoperative complications related to reduced ventilation due to pneumoperitoneum on the other. Retractor-based laparoscopy offers an operative technique reducing anesthesia risks. We report the case of laparoscopic hysterectomy in an obese patient of short stature. Laparoscopic supracervical hysterectomy was performed by a hybrid approach of a retractor system exerting its effects on lifting the abdominal wall through gravity and conventional laparoscopy, thus bypassing the adverse effects of pneumoperitoneum on ventilation.

    Laparoscopy offers some evidence of benefit compared to open rectal surgery. Robotic rectal surgery is evolving into an accepted approach. The objective was to analyze and compare laparoscopic and robotic rectal surgery learning curves with respect to operative times and perioperative outcomes for a novice minimally invasive colorectal surgeon. One hundred and six laparoscopic and 92 robotic LAR rectal surgery cases were analyzed. All surgeries were performed by a surgeon who was primarily trained in open rectal surgery. Patient characteristics and perioperative outcomes were analyzed. Operative time and CUSUM plots were used for evaluating the learning curve for laparoscopic versus robotic LAR. Laparoscopic versus robotic LAR outcomes feature initial group operative times of 308 (291-325) min versus 397 (373-420) min and last group times of 220 (212-229) min versus 204 (196-211) min-reversed in favor of robotics; major complications of 4.7 versus 6.5 % (NS), resection margin involvement of 2.8 versus 4.4 % (NS), conversion rate of 3.8 versus 1.1 (NS), lymph node harvest of 16.3 versus 17.2 (NS), and estimated blood loss of 231 versus 201 cc (NS). Due to faster learning curves for extracorporeal phase and total mesorectal excision phase, the robotic surgery was observed to be faster than laparoscopic surgery after the initial 41 cases. CUSUM plots demonstrate acceptable perioperative surgical outcomes from the beginning of the study. Initial robotic operative times improved with practice rapidly and eventually became faster than those for laparoscopy. Developing both laparoscopic and robotic skills simultaneously can provide acceptable perioperative outcomes in rectal surgery. It might be suggested that in the current milieu of clashing interests between evolving technology and economic constrains, there might be advantages in embracing both approaches.

    Pelvic kidney stones remain a unique challenge to the endourologists. Treatment options include open surgery, extracorporeal shockwave lithotripsy, percutaneous nephrolithotomy (PNL), retrograde intrarenal surgery, and laparoscopy assisted PNL (LA-PNL). As a minimal invasive option, LA-PNL can decrease the risk for bowel and major vessel injury. Here, we describe our experience using the LA-PNL procedures with different combinations, to treat kidney stones in multiple patients with a pelvic ectopic kidney (PEK). Eight patients, with PEK, kidney stones, and no other treatment choice, but open surgery, were included in the study. Two different laparoscopic techniques such as mesocolon dissection and transmesocolic, and four different percutaneous procedures such as standard-PNL, mini-PNL, micro-PNL, and a PNL through the renal pelvis were used for stone extraction in these patients. The mean age of patients was 25.6 ± 12.9 years and mean stone size was 524.1 ± 430.3 mm(2). Mean operation time was 150.5 ± 40.0 (77-210) min which was composed of retrograde catheterization (14.8 ± 2.9 min), laparoscopic procedure (48.7 ± 20.6 min) and PNL procedure (86.8 ± 31.1 min). Residual stones were seen in two patients (no additional treatment was need), while a 'stone-free' procedure was achieved in six patients (75.0 %). On the post-operative first month visit, a stone was observed on radiological examinations in only one patient (87.5 % stone-free). Mean hospitalization time was 2.8 ± 0.9 days. No perioperative or post-operative complication was observed in all patients. LA-PNL surgery is a safe and effective option for treatment of PEK stones, and has several alternative approaches.

    None of the in-vitro and in-vivo methods listed permits on unambiguous diagnosis when applied alone, owing to the fact that similar or even identical findings are obtained for various individual parameters in different thyroid diseases. Further, especially the in-vitro tests are also subject to extrathyroidal effects which may mask the typical findings. The limited and varying specificity and sensitivity of the tests applied, as well as the falsification of results caused by the patients' idiosyncracies and the methodology, make it necessary to interpret and evaluate the in-vivo and in-vitro findings only if the clinical situation (anamnesis and physical examination) is known. For maximum diagnostic quality of the tests, the initial probability of the assumed type of thyroid disease must be increased (formulation of the clinical problem). The concepts of exclusion diagnosis and identification must be distinguished as well as the diagnosis of functional disturbances on the one hand and of thyroid diseases on the other. Both of this requires a qualified, specific and detailed anamnesis and examination procedure, and the clinical examination remains the obligatory basis of clinical diagnostics. In case of inexplicable discrepancies between the clinical manifestations and the findings obtained with specific methods, or between the findings obtained with a specific method, the patient should be referred to an expert institution, or the expert institution should be consulted.

    2012-10-01

    The incidence of acute abdominal pain ranges between 5-10% of all visits at emergency department. Abdominal emergencies of hospital visits may include surgical and non-surgical emergencies. The most common causes of acute abdomen are appendicitis, biliary colic, cholecystitis, diverticulitis, bowel obstruction, visceral perforation, pancreatitis, peritonitis, salpingitis, mesenteric adenitis and renal colic. Good skills in early diagnosis require a sound knowledge of basic anatomy and physiology of gastrointestinal tract, which are reflected during history taking and particularly, physical examination of the abdomen. Advanced diagnostic approaches such as radiography and endoscopy enhance the treatment for acute abdomen including pharmacological and surgical treatment. Therapeutic endoscopy, interventional radiology treatment and therapy using adult laparoscopy are the common modalities for treating patients with acute abdomen.

    Full Text Available PURPOSE: Radical nephrectomy can be performed using open or laparoscopic (with or without hand assistance methods, and most recently using the da Vinci Surgical Robotic System. We evaluated the perioperative outcomes using a contemporary cohort of patients undergoing radical nephrectomy by one of the above 4 methods performed by the same surgeon. MATERIALS AND METHODS: The relevant clinical information on 57 consecutive patients undergoing radical nephrectomy from September 2000 until July 2004 by a single surgeon was entered in a Microsoft Access DatabaseTM and queried. Following appropriate statistical analysis, p values < 0.05 were considered significant. RESULTS: Of 57 patients, the open, robotic, laparoscopy with or without hand assistance radical nephrectomy were performed in 18, 6, 21, and 12 patients, respectively. The age, sex, body mass index (BMI, incidence of malignancy, specimen and tumor size, tumor stage, Fuhrman grade, hospital stay, change in postoperative creatinine, drop in hemoglobin, and perioperative complications were not significantly different between the methods. While the estimated median blood loss, postoperative narcotic use for pain control, and hospital stay were significantly higher in the open surgery method (p < 0.05, the median operative time was significantly shorter compared to the robotic method (p = 0.02. Operating room costs were significantly higher in the robotic and laparoscopic groups; however, there was no significant difference in total hospital costs between the 4 groups. CONCLUSIONS: The study demonstrates that radical nephrectomy can be safely performed either by open, robotic, or laparoscopic with or without hand assistance methods without significant difference in perioperative complication rates. A larger cohort and longer follow up are needed to validate our findings and establish oncological outcomes.

    Health management (HM) in any engineering systems requires adequate understanding about the system s functioning; a sufficient amount of monitored data; the capability to extract, analyze, and collate information; and the capability to combine understanding and information for HM-related estimation and decision-making. Rotorcraft systems are, in general, highly complex. Obtaining adequate understanding about functioning of such systems is quite difficult, because of the proprietary (restricted access) nature of their designs and dynamic models. Development of an EIM (exact inverse map) solution for rotorcraft requires a process that can overcome the abovementioned difficulties and maximally utilize monitored information for HM facilitation via employing advanced analytic techniques. The goal was to develop a versatile HM solution for rotorcraft for facilitation of the Condition Based Maintenance Plus (CBM+) capabilities. The effort was geared towards developing analytic and reasoning techniques, and proving the ability to embed the required capabilities on a rotorcraft platform, paving the way for implementing the solution on an aircraft-level system for consolidation and reporting. The solution for rotorcraft can he used offboard or embedded directly onto a rotorcraft system. The envisioned solution utilizes available monitored and archived data for real-time fault detection and identification, failure precursor identification, and offline fault detection and diagnostics, health condition forecasting, optimal guided troubleshooting, and maintenance decision support. A variant of the onboard version is a self-contained hardware and software (HW+SW) package that can be embedded on rotorcraft systems. The HM solution comprises components that gather/ingest data and information, perform information/feature extraction, analyze information in conjunction with the dependency/diagnostic model of the target system, facilitate optimal guided troubleshooting, and offer

    Actually, many laboratories tend to acquire pre analytic automates to prepare specimens for analysis. For haemostasis, these pre analytical modules are not always in agreement with the recommendations from the Groupe d'étude de l'hémostase et de la thrombose (GEHT). For example in the MPA C10 module (Roche Diagnostics) the speed of centrifugation was not rather fast compared with the GEHT recommandations. Then, to be able to use this automate for routine coagulation assays, we compared results of Quick time, activated partial prothombin time, fibrinogen, factor II, factor V, factor VII, factor X and antithrombin levels and unfractioned heparin anti-Xa activity measurement after MPA (1,885 g - 999 sec) or GEHT (2,500 g - 900 sec) protocol of centrifugation. First, we verified platelet counts: in 82% of specimens, the platelet counts were under 10.10(9)/L after centrifugation on MPA module. Moreover, a good correlation was observed in all comparisons. Then we concluded the MPA C10 module was usable for routine coagulation tests.

    Full Text Available Diagnostic thoracoscopy in patients with pleural effusion of unclear origin mostly provides the correct diagnosis. Results from published reports of previous researches are not uniform. In 47 male and 20 female patients with pleural effusion of unknown etiology, after receiving negative results obtained from cytological finding of pleural effusion and percutaneous needle biopsy, thoracoscopy with biopsy of one or both pleurae was performed. Procedure was done in local anesthesia using Stortz rigid thoracoscope. In 37 patients with malignant disease (primary or metastatic diagnosis was confirmed histopathologically in 31 patient (81.12%. In 27 patients with inflammatory pleural disease diagnosis was confirmed histopathologically in 22 patients (81.4%. Among 11 patients with specific pleural effusions, tuberculosis was confirmed in 10 (90.91%. Normal finding in cases of spontaneous pneumothorax and pulmonary embolism was taken as a positive result. Total number of positive findings was 55 (82.10%. In one patient, the third spontaneous pneumothorax was the indication for thoracoscopy, and after numerous bullae were seen during the procedure, talcum powder pleurodesis was done. In four patients low intensity subcutaneous emphysema occurred one day after thoracoscopy. It can be concluded that thoracoscopy in local anesthesia out of the operating room is good and practical method for solving the unclear pleural effusions, with neglectable rate of complications.

    Both patients and the medical profession are quick to embrace new technology, particularly when it may replace an existing surgical procedure. Unfortunately, the rapidity of acceptance is rarely associated with careful evaluation. Laparoscopy is a recent example of such widely embraced technology. Studies of laparoscopy that yielded good comparative data to more traditional methods were slow to accrue. This led to the exposure of its shortcomings through governmental reports and the lay press. To prevent this from happening in thoracoscopy, two types of studies are required so that valid conclusions about the new technology can be drawn. The first is an accounting of the new technology as procedures evolve around it. The data collected in such a study should contain basic information, including the indications for the procedure, how it was performed, procedure length, associated complications, and patient outcome. Such information provides a broad profile of the technology, emphasizing from the outset its potential strengths and weaknesses. The second type of study involves a more detailed concurrent comparison of the specific procedures utilizing this technology to the established traditional methods. Such randomized studies help to firmly establish through scientific process the place of the new technology. The Video-Assisted Thoracic Surgery Study Group was organized in early 1992 to address these concerns. From an initial four surgeons the group has grown to include more than 41 institutions. Currently the group is collecting data in a registry and has established three clinical trials to evaluate video-assisted thoracic surgery.(ABSTRACT TRUNCATED AT 250 WORDS)

    2014-01-01

    Full Text Available A 79-year-old female was referred to our Gynecologic Department presenting with a pelvic magnetic resonance imaging (MRI, showing an adnexal mass, later confirmed at the pelvic examination. The patient’s routine laboratory tests were normal. A sonographic examination was performed with inconclusive results. Although the ultrasonography excluded the presence of vascularization and malignant degeneration, the adnexal localization appeared to be dubious. The laparoscopy and the subsequent histologic examination revealed the presence of a mucocele of the appendix. The following case report focuses the attention on a misdiagnosis of appendiceal mucocele. The misdiagnosis caused no negative impact on the treatment that in this case was adequate and successful.

    During laparoscopic surgery, carbon dioxide (CO2) pneumothorax can develop due to a congenital defect in the diaphragm. We present a case of a spontaneous massive left-sided pneumothorax that occurred during laparoscopy-assisted gastrectomy, because of an escape of intraperitoneal CO2 gas, under pressure, into the pleural cavity through a congenital defect in the esophageal hiatus of the left diaphragm. This was confirmed on intraoperative chest radiography and laparoscopic inspection. This CO2 pneumothorax caused tolerable hemodynamic and respiratory consequences, and was rapidly reversible after release of the pneumoperitoneum. Thus, a conservative approach was adopted, and the remainder of the surgery was completed, laparoscopically. Due to the high solubility of CO2 gas and the extra-pulmonary mechanism, CO2 pneumothorax with otherwise hemodynamically stable conditions can be managed by conservative modalities, avoiding unnecessary chest tube insertion or conversion to an open procedure.

    Carbon dioxide is the standard insufflation gas for laparoscopy. However, in many areas of the world, bottled carbon dioxide is not available. Laparoscopy offers advantages over open surgery and has been practiced using filtered room air insufflation since 2006 at Bongolo Hospital in Gabon, Africa. Our primary goal was to evaluate the safety of room air insufflation related to intraoperative and postoperative complications. Our secondary aim was to review the types of cases performed laparoscopically at our institution. This retrospective review evaluates laparoscopic cases performed at Bongolo Hospital between January 2006 and December 2013. Demographic and perioperative information for patients undergoing laparoscopic procedures was collected. Insufflation was achieved using a standard, oil-free air compressor using filtered air and a standard insufflation regulator. A total of 368 laparoscopic procedures were identified within the time period. The majority of cases were gynecologic (43%). There was a 2% (8/368) complication rate with one perioperative death. The 2 complications related to insufflation were episodes of hypotension responsive to standard corrective measures. No intracorporeal combustion events were observed in any cases in which the use of diathermy and room air insufflation were combined. The other complications and the death were unrelated to the use of insufflation with air. Insufflation complications with room air occurred in our study. However, the complications related to insufflation with room air in our study were no different than those described in the literature using carbon dioxide. As room air is less costly than carbon dioxide and readily available, confirming the safety of room air insufflation in prospective studies is warranted. Room air appears to be safe for establishing and maintaining pneumoperitoneum, making laparoscopic surgery more accessible to patients in low-resource settings.

    Background The acute abdomen is a frequent entity at the Emergency Department (ED), which usually needs rapid and accurate diagnostic work-up. Diagnostic work-up with imaging can consist of plain X-ray, ultrasonography (US), computed tomography (CT) and even diagnostic laparoscopy. However, no evidence-based guidelines exist in current literature. The actual diagnostic work-up of a patient with acute abdominal pain presenting to the ED varies greatly between hospitals and physicians. The OPTIMA study was designed to provide the evidence base for constructing an optimal diagnostic imaging guideline for patients with acute abdominal pain at the ED. Methods/design Thousand consecutive patients with abdominal pain > 2 hours and < 5 days will be enrolled in this multicentre trial. After clinical history, physical and laboratory examination all patients will undergo a diagnostic imaging protocol, consisting of plain X-ray (upright chest and supine abdomen), US and CT. The reference standard will be a post hoc assignment of the final diagnosis by an expert panel. The focus of the analysis will be on the added value of the imaging modalities over history and clinical examination, relative to the incremental costs. Discussion This study aims to provide the evidence base for the development of a diagnostic algorithm that can act as a guideline for ED physicians to evaluate patients with acute abdominal pain.

    The advent of molecular tools capable of subclassifying eosinophilia has changed the diagnostic and clinical approach to what was classically called hypereosinophilic syndrome. To review the etiologies of eosinophilia and to describe the current diagnostic approach to this abnormality. Literature review. Eosinophilia is a common, hematologic abnormality with diverse etiologies. The underlying causes can be broadly divided into reactive, clonal, and idiopathic. Classically, many cases of eosinophilia were grouped together into the umbrella category of hypereosinophilic syndrome, a clinical diagnosis of exclusion. In recent years, an improved mechanistic understanding of many eosinophilias has revolutionized the way these disorders are understood, diagnosed, and treated. As a result, specific diagnoses can now be assigned in many cases that were previously defined as hypereosinophilic syndrome. Most notably, chromosomal rearrangements, such as FIP1L1-PDGFRA fusions caused by internal deletions in chromosome 4, are now known to be associated with many chronic eosinophilic leukemias. When present, these specific molecular abnormalities predict response to directed therapies. Although an improved molecular understanding is revolutionizing the treatment of patients with rare causes of eosinophilia, it has also complicated the approach to evaluating and treating eosinophilia. Here, we review causes of eosinophilia and present a framework by which the practicing pathologist may approach this diagnostic dilemma. Finally, we consider recent cases as clinical examples of eosinophilia from a single institution, demonstrating the diversity of etiologies that must be considered.

    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 Abstract Background The criterion for dementia implicit in DSM-IV is widely used in research but not fully operationalised. The 10/66 Dementia Research Group sought to do this using assessments from their one phase dementia diagnostic research interview, and to validate the resulting algorithm in a population-based study in Cuba. Methods The criterion was operationalised as a computerised algorithm, applying clinical principles, based upon the 10/66 cognitive tests, clinical interview and informant reports; the Community Screening Instrument for Dementia, the CERAD 10 word list learning and animal naming tests, the Geriatric Mental State, and the History and Aetiology Schedule – Dementia Diagnosis and Subtype. This was validated in Cuba against a local clinician DSM-IV diagnosis and the 10/66 dementia diagnosis (originally calibrated probabilistically against clinician DSM-IV diagnoses in the 10/66 pilot study. Results The DSM-IV sub-criteria were plausibly distributed among clinically diagnosed dementia cases and controls. The clinician diagnoses agreed better with 10/66 dementia diagnosis than with the more conservative computerized DSM-IV algorithm. The DSM-IV algorithm was particularly likely to miss less severe dementia cases. Those with a 10/66 dementia diagnosis who did not meet the DSM-IV criterion were less cognitively and functionally impaired compared with the DSMIV confirmed cases, but still grossly impaired compared with those free of dementia. Conclusion The DSM-IV criterion, strictly applied, defines a narrow category of unambiguous dementia characterized by marked impairment. It may be specific but incompletely sensitive to clinically relevant cases. The 10/66 dementia diagnosis defines a broader category that may be more sensitive, identifying genuine cases beyond those defined by our DSM-IV algorithm, with relevance to the estimation of the population burden of this disorder.

    Already 94 years ago in 1910, Dr. Hans Christian Jacobaeus performed the first clinical laparoscopic surgery in Stockholm. His pioneering procedure was based on the animal experiments of Georg Kelling (1866-1945), a German physician from Dresden, who performed the first laparoscopic intervention in 1901 using a Nitze cystoscope in a dog. In 1910 Jacobaeus published his first experiences with laparoscopic surgery in the Münchner Medizinische Wochenschrift under the title "The possibility to perform cystoscopy in examinations of serous cavities." He used this technique for diagnostic purposes in unclear abdominal complaints and functional impairment. Jacobaeus was the first who pointed out the possibility of causing injury to organs, especially the gut, by inserting the trocar. In 1910 Jacobaeus recognized the immense diagnostic and therapeutic possibilities of laparoscopic surgery, but also the difficulties and limits. He also was the first who recognized the need to complete training sessions on animals and corpses. He demanded the development of special laparoscopic instruments to optimize and simplify the operation.

    A 41-year-old patient presented several episodes of desaturation during a gynaecological laparoscopy. The major complication of this procedure is the venous air embolism. Several other side-effects have been reported: heart rate disorders, subcutaneous emphysema or pneumothorax. Pleural effusions during gynaecologic laparoscopy are apparently rare and the volume of effusion must be important to induce clinical symptoms. This fact can probably explain the frequent difficulty of diagnosis. The ...

    Full Text Available Background. National guidelines prompted the implementation of a designated two-week wait referral pathway to facilitate the early diagnosis of sarcomas, to improve treatment outcomes. Methods. Patients referred to the Cambridge Sarcoma Diagnostic Clinic between January 2013 and December 2014 were identified through the electronic appointments system. Information was retrospectively retrieved about patient characteristics and details of the diagnostic pathway. Results. 17.3% of patients referred (69/397 were diagnosed with a malignancy. Of these, 59.3% (41/69 had primary sarcomas, 17.4% (12/69 had metastatic cancer, and 23.2% (16/69 had a different primary malignancy. 15% of the 41 sarcomas were 10 cm. Sarcomas diagnosed through this clinic represented 13% (41/315 of sarcomas managed at the centre during the same 2 years. Conclusion. While we achieved the target of 10% (41/397 sarcoma diagnosis rate in the rapid access clinic, only 15% of these were <5 cm better prognosis lesions. This calls into question the “real world” impact of such diagnostic clinics on early diagnosis of sarcomas. In order to enhance generic cancer diagnostic skills, training in these diagnostic clinics could be usefully integrated into national training curricula for both surgical and nonsurgical oncologists.

    INTRODUCTION Retrorectal tumors are uncommon and the etiology diverse. Literature to define the preoperative diagnosis and plan the intraoperative management are uncommon. PRESENTATION OF CASE We describe a case of a 44 year old patient with a laparoscopic approach for the removal of a retrorectal tumor and emphasize on the preoperative diagnostics and the intraoperative, minimal invasive approach. DISCUSSION Especially because these tumors are rare and often an incidental finding in gynecologic surgery, it is important to know the various differential diagnoses and its consequences with the laparoscopic approach. CONCLUSION We suggest the laparoscopic approach in cases of retroperitoneal cysts of unknown origin is ideal also because anatomic structures, mostly nerves, can be easily spared. PMID:25194610

Wilson and Madison – 1989 describe the use of laparoscopy to diagnose an abdominal retained testes. Since then numerous laparoscopic cryptorchidectomy techniques have been described. Aims: In the encountered specialty literature there are few reports in which standing laparoscopic cryptorchidectomy could not be performed in stallions including miniature horse too. Because there are no informations regarding laparoscopic surgery in large animals in romanian literature this report describes the surgical management of a Canadian pony diagnosed with partial abdominal unilaterally cryptorchidism at which laparoscopic castration has failed and the removal of the retained testicle has been made through inguinal celiotomy. Materials and Methods: A 4-year-old unilaterally cryptorchid Canadian pony was admitted for castration. The left testis was in the scrotum, but neither the right testis nor the right epididymis could be located by external palpation of the right inguinal canal. The proposed treatment was laparoscopic cryptorchidectomy with pony standing in stock. With a long-handled forceps inserted into the abdominal cavity, the testis cord is gently grasped and moderate traction without success in bringing the testicle into the abdomen - retained testis. After the failure of laparascopic cryptorchidectomy but having an exact diagnosis - partial

    We performed two image reading experiments in order to investigate the diagnostic capability of I-123 IMP SPECT obtained by the ring type SPECT scanner in cerebro-vascular disease. Fourteen physicians diagnosed SPECT images of 55 cases with reference to clinical neurological information, first without brain XCT images and second with XCT images. Each physician detected perfusion defects and redistributions of I-123 IMP and assigned a confidence level of abnormality for these SPECT findings by means of five rating method. From results obtained by ROC analysis, we concluded as follows. (1) Generally, I-123 IMP SPECT is a stable diagnostic modality in the diagnosis of cerebro-vascular disease and the image reading of XCT had no effects on the diagnosis of SPECT on the whole of physician. (2) However, there were unnegligible differences among individuals in the detectability of findings and the effect of XCT image reading. (3) Detectability of redistribution of I-123 IMP was lower than that of perfusion defect and inter-observer variation in the diagnostic performance for redistribution was larger than that of perfusion defect. The results suggest that it is necessary to standardize diagnostic criteria among physicians for redistribution of I-123 IMP. (author).

    2015-01-01

    Full Text Available Background: Image-guided percutaneous drainage with antimicrobial agents is the standard modality of treatment of liver abscess. Open surgical drainage, and lately laparoscopic drainage becomes useful in selected patients. Nigeria is awakening late to the laparoscopic surgery revolution. Public health institutions have started making enormous investments in minimal access surgery, which can augment deficient diagnostic capacities. Objective: To describe the outcomes of the patients who underwent laparoscopic liver abscess drainage at the Federal Medical Centre, Owerri. Materials and Methods: A retrospective analysis of the laparoscopic liver abscess drainage procedures done between the period September 2007 and December 2012 was done. Results: A total of eight patients in the study period were worked up for abscess surgical drainage based on ultrasound (seven cases and computed tomography (one case supported localized collection in the liver. Intraoperatively, one patient was noticed to have nodules on the liver that was later confirmed as hepatocellular carcinoma. Operating time ranged from 37 to 126 min. There was no conversion to open surgery. On the follow-up, one patient had residual abscess of 45 mm diameter size, after 6 weeks, and in whose aspirate acid-fast bacilli were identified. Conclusion: Laparoscopic drainage should be considered in the management of liver abscess.

    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 evaluate the efficacy and cosmetic result of suprapubic single incision laparoscopic surgery(SSILS) in the treatment of rectosigmoid cancer. Clinicopathological data of 16 patients undergoing SSILS and 122 undergoing conventional laparoscopic surgery(CLS) for sigmoid colon and upper rectal cancer in the Nanfang Hospital from August 2011 to July 2012 were retrospectively analyzed. The patients were analyzed with propensity score matching at a ratio of 1 to 2 by logistic regression analysis. The matching covariates included age, gender, body mass index, American Society of Anesthesiologists(ASA) score, tumor location, tumor diameter, pathologic TNM stage, previous abdominal surgery. After matching, 48 patients (16 SSILS and 32 CLS) were enrolled in the study. The SSILS group comprised of 13 (81.3%) males with mean age of (56.4±13.4) years. The CLS group comprised of 23(71.9%) males with mean age of (55.6±13.7) years. Postoperative short-term parameters, oncologic efficacy and cosmetic result were compared between the two groups. The male gender ratio, age, body mass index, ASA score, tumor location, tumor diameter, tumor differentiation, depth of invasion, lymph node metastasis, TNM stage, previous abdominal surgery were comparable between the two groups. As compared to CLS group, less incision length [(4.8±1.5) cm vs. (6.8±1.2) cm, U=63.000, P=0.000], shorter time to ambulation [(2.6±1.0) days vs. (3.9±1.5) days, U=116.500, P=0.002], shorter hospital stay [(8.4±5.3) days vs.(9.2±3.1) days, U=139.000, P=0.010] and less postopertive pain(Visual Analogue Scale: 4.3±1.4 vs. 5.2±1.1 at day 3, t=2.457, P=0.018; 3.7±1.0 vs. 4.6±1.0 at day 4, t=2.700, P=0.010; 3.3±0.8 vs. 4.0±1.0 at day 5, t=2.466, P=0.017) were observed in SSILS group.

    To compare feasibility and surgical outcome of laparoscopic gynecologic surgery between obese, overweight, normal-weight, and underweight women. Retrospective case control study (Canadian Task Force classification II-3). Surgery Unit of Minimally Invasive Gynaecology. A total of 503 women who underwent laparoscopic procedures for both benign disease and malignancies. Four main categories of gynecologic disease were identified: uterine fibroids, benign adnexal masses, endometriosis, and endometrial cancer (stage I). For each category patients were divided into 4 groups: underweight (BMI obese (BMI ≥30 kg/m(2)). Selected outcomes were duration of surgery, rate of laparotomy conversion, intraoperative and postoperative complications, and duration of hospital stay. No statistical difference regarding demographic data, surgical and medical history, and intraoperative findings was present between groups. No laparotomy conversion occurred. Regarding duration of surgery, we found no statistical difference among the BMI groups with regard to benign diseases, whereas pelvic lymphadenectomy in obese patients with endometrial cancer had a statistically significant longer duration than in the control group (122 +/- 47 min vs 65 +/- 21 min, p <.001). The postoperative complication rate was 0.01%: 3 cases of blood transfusion and 1 case of hemoperitoneum among myomectomies; 1 ureteral fistula in surgery for pelvic endometriosis; and 1 case of postoperative lymphocele in endometrial cancer group. No statistically significant difference was found in duration of hospital stay among the BMI groups in any of the categories of disease. For each category we conducted an analysis to identify any possible risk factors other than BMI in the surgical outcomes. Laparoscopic approach in the various applications of gynecologic surgery does not appear to be significantly influenced by BMI in terms of surgical outcomes, laparotomy conversion rate, intraoperative and postoperative complications

    Over the last several years, reflectometry has grown in importance as a diagnostic for both steady-state density Profiles as well as for the investigation of density fluctuations and turbulence. As a diagnostic for density profile measurement, it is generally believed to be well understood in the tokamak environment. However, its use as a fluctuation diagnostic is hampered by a lack of quantitative experimental understanding of its wavenumber sensitivity and spatial resolution. Several researchers, have theoretically investigated these questions. However, prior to the UCLA laboratory investigation, no group has experimentally investigated these questions. Because of the reflectometer's importance to the world effort in understanding plasma turbulence and transport, UCLA has, over the last year, made its primary Task IIIA effort the resolution of these questions. UCLA has taken the lead in a quantitative experimental understanding of reflectometer data as applied to the measurement of density fluctuations. In addition to this, work has proceeded on the design, construction, and installation of a reflectometer system on UCLA's CCT tokamak. This effort will allow a comparison between the improved confinement regimes (H-mode) observed on both the DIII-D and CCT machines with the goal of achieving a physics understanding of the phenomena. Preliminary investigation of a new diagnostic technique to measure density profiles as a function of time has been initiated at UCLA. The technique promises to be a valuable addition to the range of available plasma diagnostics. Work on advanced holographic reflectometry technique as applied to fluctuation diagnostics has awaited a better understanding of the reflectometer signal itself as discussed above. Efforts to ensure the transfer of the diagnostic developments have continued with particular attention devoted to the preliminary design of a multichannel FIR interferometer for MST.

    Full Text Available Background: Endometriosis is one of the major problems in current gynecology due to steady increase of its incidence, involvement of young females, high frequency of infertility and difficulties with diagnostics and treatment. Confirmation of diagnosis of advanced endometriosis is still within the competence of research centers and big federal treatment establishments.Aim: To improve ultrasound diagnostics and to develop an algorithm of assessment in retrocervical endometriosis.Materials and methods: Seventy two females were assessed laparoscopically due to a gynecology disorder or infertility. Based on intraoperational data and results of pathomorphological assessments, two groups were formed: group 1 (control group, n = 26 comprised patients in reproductive age who had been admitted for elective surgery due to a gynecological disorder. Group 2 (main group, n = 46 included patients with various types of endometriosis. Patients from group 2 were divided into 3 subgroups: 2а (n = 17 – with superficial forms of external genital endometriosis; 2b (n = 18 – with endometrioid cysts; 2c (n = 11 – with deep infiltrative types of endometriosis.Results: Patients with superficial external genital endometriosis were characterized by positive symptom of “folding” (“freezing” of posterior uterine surface and of the walls of adjacent intestine. In endometriosis of posterior surface of cervix uteri, the diagnosis made by an ultrasound assessmentin 100% matched the diagnosis set during surgery, whereas if sacrouterine ligaments were involved, the diagnostic match was only 3%. In the group of patients with endometrioid cysts, in most of cases the cysts had specific ultrasound signs; coincidence of an ultrasound and a morphological diagnosis was seen in 98% of cases. Most cases of deep infiltrative endometriosis showed involvement of sacrouterine ligaments (72% and of parametrium (81%. There was a positive folding sign and a “Indian headdress

    AIM: To investigate the safety and feasibility of dezozine in gynecological lapa-raoscopy under epidural anesthesia. METHODS; Sixty ASA I or II patients, aged 18-55 yr, undergoing gynecological laparoscopy surgery, were randomly divided into 2 groups (n = 30 each): Dezocing group (group D) and Fentanyl group (group F). PeTCO2 and Ramsay sedation scales were recorded at the time points followed: pre-anesthesia ( T0), 10 min after administration (T1) instantly after pneumoperitoneum (T2), 30 min (T3) and 60 min (T4) after pneumoperitoneum, 5 min after eliminating pneumoperitoneum (T5). The incidences of side effects such as nausea, vomiting, algor and respiratory depression was observed. RESULTS:Ramsay seda- tion scales were not statistically different between the two groups. D group's PEt CO2 was lower than of F group at the time points of T3 and T4. The incidences of nausea, vomiting and respiratory depression were higher in F group (P<0. 05). CONCLUSION: Dezocine has significant advantages over fentanyl to assist epidural anesthesia in gynecological laparoscopy with respect to reduce discomfort during pneumoperitoneum, better analgesia and sedation, less side effects.%目的:探讨地佐辛辅助硬膜外麻醉在妇科腹腔镜手术中应用的可行性.方法:选择硬膜外麻醉下行妇科腹腔镜手术患者60例,ASA Ⅰ~Ⅱ级,年龄18~55岁,手术时间均不超过两个小时,随机均分为地佐辛组(D组)和芬太尼组(F组).记录给药前(T0)、给药后10 min (T1)、气腹后即刻(T2)、气腹后30 min(T3)、气腹后60 min(T4)、气腹消除后5 min(T5)的呼气末二氧化碳分压(PET CO2)及Ramsay镇静评分.观察两组患者出现恶心、呕吐、寒颤、呼吸抑制(呼吸频率低于8次/min或脉搏血氧饱和度(SpO2)低于90%)等不良反应的发生率.结果:两组患者的Ramsay镇静评分无统计学差异,T3、T4时点D组PFTCO2低于F组(P<0.05),恶心、呕吐、呼吸抑制的发生率F组明显高于D组.结论

    Inspired by natural orifice translumenal endoscopic surgery (NOTES), the authors launched a development of novel endoscopic irrigation and suction (I/S) catheter for "laparoscopy-like" I/S in flexible gastrointestinal (GI) endoscopy. The aims were to describe its basic research and development (R&D) process and to estimate its performance in both preclinical and clinical settings. In basic R&D phase, a layout of side hole at apex nozzle of endoscopic I/S (EIS) catheter were theoretically calculated and designed. Material of nozzle was selected based on the strength analysis. The performance of final prototype EIS catheter was then assessed preclinically in the porcine stomach, to compare with conventional endoscopic "tip irrigation" and "tip suction" as control. After regulatory clearance, safety and feasibility of I/S using EIS catheter were clinically assessed by endoscopists in small number of patients. Bench tests revealed 0.4 mm in diameter, 24 holes, and 6-8 holes per circumference as most suitable layout of side holes, and polyetheretherketone as an optimal nozzle material, respectively. Time to inject 500 mL saline with the EIS catheter was significantly shorter than tip irrigation (101 ± 3.1 seconds versus 154 ± 3.1 seconds; P suction was significantly weaker than conventional endoscopic tip suction, though it remained within the practical range. No mucosal injuries were noted in the EIS suction. In clinical assessments for human use, no adverse events were observed, and high degree of satisfaction for endoscopists was obtained. The newly developed EIS catheter is safely used with satisfactory performance in flexible GI endoscopy.

    Laparoscopy surgery has been widely used for many decades and combined laparoscopic procedures have become favorable choices for concomitant pathologies in the abdomen. However, the type of combination procedures and their safety in obese women have not been well elucidated in obese women. Here we retrospectively reported 147 obese women underwent combined laparoscopic gynecological surgery and cholecystectomy/appendicectomy in our hospital from January 2003 to December 2011. Of the total number of patients (n = 147), various laparoscopic gynecological surgeries were combined with laparoscopic cholecystectomy in 93 patients, and were combined with laparoscopic appendectomy in the rest 54 patients. Patients' ages ranged from 24 to 55 years with an average of 33 years. Our results showed that combined procedures caused various operative time and blood loss, with no difference considering the time to resume oral intake and length of hospital stay. Intraoperative complications occurred in a total of 7 patients (4.8%). None of the patients suffered from major complications after laparoscopic surgery, and minor postoperative complications occurred in 30 patients (20.4%). The follow-up period ranged from 6 to 24 months (average, 18.5 months). None of the patients developed complications during follow-up, except that one patient suffered from colporrhagia. Our results further suggest that the combined abdominal laparoscopic procedures of gynecologic and general surgery are safe and economic choices for obese women, and benefit patients in many ways including lesser pain, shorter hospital stays and earlier recovery.

    Due to their relative scarcity and to limit single-center bias, multi-center data are needed to study femoral hernias. The aim of this study was to evaluate outcomes and quality of life (QOL) following laparoscopic vs. open repair of femoral hernias. The International Hernia Mesh Registry was queried for femoral hernia repairs. Laparoscopic vs. open techniques were assessed for outcomes and QOL, as quantified by the Carolinas Comfort Scale (CCS), preoperatively and at 1, 6, 12, and 24 months postoperatively. Outcomes were evaluated using the standard statistical analysis. A total of 80 femoral hernia repairs were performed in 73 patients: 37 laparoscopic and 43 open. There was no difference in mean age (54.7 ± 14.6 years), body mass index (24.2 ± 3.8 kg/m(2)), gender (60.3 % female), or comorbidities (p > 0.05). The hernias were recurrent in 21 % of the cases with an average of 1.23 ± 0.6 prior repairs (p > 0.1). Preoperative CCS scores were similar for both groups and indicated that 59.7 % of patients reported pain and 46.4 % had movement limitations (p > 0.05). Operative time was equivalent (47.2 ± 21.2 vs. 45.9 ± 14.8 min, p = 0.82). There was no difference in postoperative complications, with an overall 8.2 % abdominal wall complications rate (p > 0.05). The length of stay was shorter in the laparoscopic group (0.5 ± 0.6 vs. 1.3 ± 1.6 days, p = 0.02). Follow-up was somewhat longer in the open group (23.8 ± 10.2 vs. 17.3 ± 10.9 months, p = 0.02). There was one recurrence, which was in the laparoscopic group (3.1 vs. 0 %, p = 0.4). QOL outcomes at all time points demonstrated no difference for pain, movement limitation, or mesh sensation. Postoperative QOL scores improved for both groups when compared to preoperative scores. In this prospective international multi-institution study of 80 femoral hernia repairs, no difference was found for operative times, long-term outcomes, or QOL in the treatment of femoral

    Uterine rupture is an uncommon complication following termination of pregnancy and is usually accompanied by severe lower abdominal pain and shock caused by intra-abdominal hemorrhage. Laparotomy should be carried out promptly in order to repair the uterus or even to resect the uterus. Here we present a case of uterine rupture of a scarred uterus, which occurred during a second-trimester induced abortion. The patient was successfully treated by laparoscopy with the help of laparoscopic ultrasound. This case suggests an alternative, effective approach to the diagnosis and treatment of uterine rupture. © 2015 Japan Society of Obstetrics and Gynecology.

    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.

    This study was performed to produce transgenic Korean native goat (Capra hircus) by laparoscopic embryo transfer (ET) to overcome the limitations of ET performed by laparotomy. Transgenic embryos were produced by DNA pronuclear microinjection of in vivo zygotes. The recipient goats were synchronized for estrus by using an introvaginal progesterone devices as a controlled internal drug-releasing insert (CIDR) for 13 days and injection of 400 IU PMSG 48 h before removal of the insert. Embryos were transferred on day 3 and 4 after removal of the insert. Recipient goats were deprived of feed for 48 h, then suspended in a laparotomy cradle at an angle of 45 degrees . After obtaining a sufficient pneumoperitoneum, the laparoscope and forceps were inserted abdominally through 5 mm trocar sleeves. Examination of the ovaries and uterus was performed and then 213 embryos were transferred into the oviducts via the infundibula of 76 recipient goats. To compare pregnancy rates, ET was also performed by laparotomy in 82 recipient goats. The pregnancies in the recipient goats were diagnosed by ultrasound on day 30 after embryo transfer. The pregnancy rate with laparoscopic ET was significantly higher than with ET performed by laparotomy (46.1% vs. 28.6%, p < 0.05). In addition, the pregnancy rates were compared between ovulated and non-ovulated ovaries of the recipient goats in the laparoscopic ET group. No significant difference was observed between the pregnancy rates of ovulated and non-ovulated ovaries (41.3% vs. 33.3%, p < 0.05) suggesting that ET may also be possible in non-ovulated recipients through artificial rupture of Graafian follicles. These results suggest that laparoscopic ET is a highly efficient method for the transfer of goat embryos.

    Autoimmune chronic pancreatitis (AIP) is increasingly being recognized worldwidely, as knowledge of this entity builds up. Above all, AIP is a very attractive disease to clinicians in terms of its dramatic response to the oral steroid therapy in contrast to ordinary chronic pancreatitis. Although many characteristic findings of AIP have been described, definite diagnostic criteria have not been fully established. In the year 2002, the Japan Pancreas Society published the diagnostic criteria of AIP and many clinicians around the world use these criteria for the diagnosis of AIP. The diagnostic criteria proposed by the Japan Pancreas Society, however, are not completely satisfactory and some groups use their own criteria in reporting AIP. This review discusses several potential limitations of current diagnostic criteria for this increasingly recognized condition. The manuscript is organized to emphasize the need for convening a consensus to develop improved diagnostic criteria.

    The objective of this study was to develop diagnostic criteria for internet addiction disorder (IAD) and to evaluate the validity of our proposed diagnostic criteria for discriminating non-dependent from dependent internet use in the general population. This study was conducted in three stages: the developmental stage (110 subjects in the survey group; 408 subjects in the training group), where items of the proposed diagnostic criteria were developed and tested; the validation stage (n = 405), where the proposed criteria were evaluated for criterion-related validity; and the clinical stage (n = 150), where the criteria and the global clinical impression of IAD were evaluated by more than one psychiatrist to determine inter-rater reliability. The proposed internet addiction diagnostic criteria consisted of symptom criterion (seven clinical symptoms of IAD), clinically significant impairment criterion (functional and psychosocial impairments), course criterion (duration of addiction lasting at least 3 months, with at least 6 hours of non-essential internet usage per day) and exclusion criterion (exclusion of dependency attributed to psychotic disorders). A diagnostic score of 2 + 1, where the first two symptoms (preoccupation and withdrawal symptoms) and at least one of the five other symptoms (tolerance, lack of control, continued excessive use despite knowledge of negative effects/affects, loss of interests excluding internet, and use of the internet to escape or relieve a dysphoric mood) was established. Inter-rater reliability was 98%. Our findings suggest that the proposed diagnostic criteria may be useful for the standardization of diagnostic criteria for IAD.

    Full Text Available Objectives: the aim of this retrospective study was to evaluate early experience with laparoscopic restorative proctocolectomy by analyzing the perioperative results of surgical treatment. Patients and methods: seven major surgeries were performed in six patients with familial adenomatous polyposis and ulcerative colitis. All procedures were performed under laparoscopy at our third-level hospital from June 2003 to October 2004. Results: mean surgical time was 287.5 ± 80.7 min, and median blood loss was 300 ± 249.0 cc. There were no conversions; return of peristalsis began at 32 ± 12.4 h; average time to first oral intake was 64.0 ± 32.8 h, and mean duration of hospital stay was 9.3 ± 1.2 days. There was one case of perineal sepsis due to ileal pouch-anal anastomotic leakage, which was successfully treated with oral intake restriction, parenteral nutrition, and intra-rectal drainage. The most common postoperative complication was postoperative ileus. Conclusions: we believe that the laparoscopic approach to restorative proctocolectomy may be considerably improved in our center. Particular aspects for improvement include efforts to achieve lower operating and hospitalization times to equate our results with those reported by multicenter studies for laparoscopic colon cancer surgery. In our opinion, learning and further training opportunities should be encouraged to improve surgeon experience in the field of laparoscopy, preferably at centers specializing in restorative proctocolectomy.

    The diagnostic of nanodusty plasmas, i.e. plasmas including nano-sized dust particles, is a challenging task. For both, the diagnostic of the nanodusty plasma itself, and the in-situ diagnostic of the nanoparticles, no standard diagnostic exist. Nanodust particle size and density can be estimated using light scattering techniques, namely kinetic Mie ellipsometry and extinction measurements. The charge of the nanoparticles can be estimated from the analysis of dust density waves (DDW). Parameters like the electron density, which give information about the plasma itself, may be deduced from the DDW analysis. We present detailed investigations on nanodust in a reactive Argon-Acetylene plasma created in an rf-driven parallel plate reactor at low pressure using the above mentioned portfolio of diagnostic.

    This report summarizes an extensive effort made to understand how to effectively use the various diagnostic technologies to establish the condition of medium voltage underground cable circuits. These circuits make up an extensive portion of the electric delivery infrastructure in the United States. Much of this infrastructure is old and experiencing unacceptable failure rates. By deploying efficient diagnostic testing programs, electric utilities can replace or repair circuits that are about to fail, providing an optimal approach to improving electric system reliability. This is an intrinsically complex topic. Underground cable systems are not homogeneous. Cable circuits often contain multiple branches with different cable designs and a range of insulation materials. In addition, each insulation material ages differently as a function of time, temperature and operating environment. To complicate matters further, there are a wide variety of diagnostic technologies available for assessing the condition of cable circuits with a diversity of claims about the effectiveness of each approach. As a result, the benefits of deploying cable diagnostic testing programs have been difficult to establish, leading many utilities to avoid the their use altogether. This project was designed to help address these issues. The information provided is the result of a collaborative effort between Georgia Tech NEETRAC staff, Georgia Tech academic faculty, electric utility industry participants, as well as cable system diagnostic testing service providers and test equipment providers. Report topics include: •How cable systems age and fail, •The various technologies available for detecting potential failure sites, •The advantages and disadvantages of different diagnostic technologies, •Different approaches for utilities to employ cable system diagnostics. The primary deliverables of this project are this report, a Cable Diagnostic Handbook (a subset of this report) and an online

    Melioidosis is a severe disease that can be difficult to diagnose because of its diverse clinical manifestations and a lack of adequate diagnostic capabilities for suspected cases. There is broad interest in improving detection and diagnosis of this disease not only in melioidosis-endemic regions but also outside these regions because melioidosis may be underreported and poses a potential bioterrorism challenge for public health authorities. Therefore, a workshop of academic, government, and private sector personnel from around the world was convened to discuss the current state of melioidosis diagnostics, diagnostic needs, and future directions.

    Full Text Available Autoimmune hepatitis is a chronic hepatitis that occurs in children and adults of all ages. Diagnosis is based upon characteristic serologic and histologic findings and the exclusion of other forms of chronic liver disease. Guidelines issued by the AASLD suggest the following diagnostic considerations: The diagnosis should be made in patients with compatible clinical signs, symptoms, and laboratory abnormalities. Other conditions that can cause chronic hepatitis should be excluded. In unclear cases a standardized scoring system should be used in the assessment. In those who are negative for conventional autoantibodies, additional autoantibodies should be sought. All patients with autoimmune hepatitis and inflammatory bowel disease should undergo cholangiographic studies to exclude primary sclerosing cholangitis.   Scoring systems- A scoring system developed and subsequently revised by the International Autoimmune Hepatitis Group to standardize the diagnosis with using simplified criteria based upon titers of autoantibodies, IgG levels, liver histology, and the exclusion of viral hepatitis. Autoantibodies: assign one point if the ANA or SMA are 1:40 OR assign two points if the ANA or SMA are ≥1:80 (OR if the LKM ≥1:40 OR if the SLA is positive. IgG: assign one point if the IgG is > the upper limit of normal OR assign two points if the IgG is >1.10 times the upper limit of normal. Liver histology: assign one point if the histological features are compatible with autoimmune hepatitis OR two points if the histological features are typical of autoimmune hepatitis. Absence of viral hepatitis A probable diagnosis of autoimmune hepatitis is made if the total points are six, while a definite diagnosis is made if the total points are ≥seven.

    2014-01-01

    Familial Mediterranean fever (FMF) is the most prevalent monogenic autoinflammatory disease, mainly affecting ethnic groups living at Mediterranean basin. FMF is characterized by recurrent, self-limited episodes of fever and serositis. The diagnosis is difficult in the presence of atypical signs, which may result in significant delay in initiating treatment. As autoinflammatory diseases may have overlapping symptoms, strict diagnostic criteria are essential. Since the discovery that mutations in the gene MEFV underlie FMF, molecular genetic testing has been used as a diagnostic adjunct, especially in atypical cases. However, despite progress in the understanding of FMF disease mechanisms during the past 15 years; the diagnosis is still based on clinical criteria. Several sets of diagnostic criteria have been proposed and used. Existing diagnostic criteria should be modified to include genetic data, and need to be more widely validated.

    Recently it has been postulated that most ovarian cancers have a tubal origin. The identification of preinvasive tubal lesions would be of great interest in the early diagnosis of ovarian cancer. Optical biopsy has been developed and validated in the detection of precancerous lesions (such as Barrett's oesophagus). The first objective of this study was to assess the feasibility of optical biopsy in the study of fallopian tubes during laparoscopy. The second objective was to describe the images in benign premalignant and malignant tubes with a histopathological and immunohistochemical (p53 and Ki67 expressions) correlation. In this prospective study, 40 patients undergoing laparoscopic salpingectomy for benign conditions (benign hysterectomy), prophylactic conditions (BRCA mutation) or in case of pelvic cancers were included after obtaining informed and signed consent prior to surgery. The optical biopsy was performed on the fimbria of each tube in and ex vivo. A correlation was made with the histopathological and immunohistochemical analysis. The feasibility of optical biopsy was always confirmed during laparoscopy. The optical biopsy iconography revealed different images in benign tubal epithelium (well-defined black and grey structure), in adenomatoid tumour (tortuous architectural organization), in STIC precancerous lesion (enlarged, irregular and pleomorphic cells, dilated and distorted vessels) and in tubal metastasis of high grade serous ovarian cancer (dark neoplastic cells irregular in size and shape) CONCLUSIONS: Optical biopsy may be the first emerging mini-invasive technology that could detect tubal lesions and may be considered as a promising tool in the early detection of ovarian cancer.

    Objective By exploring natural pregnancy rate and its related influencing factors of after the operation of palace laparoscopy to infertile patients with fallopian tube, to provide basis for doctors to accurately assess the opportunity of natural pregnancy after tubal infertility and to select the appropriate pregnancy program. Methods 93 cases of infertile patients with fallopian tube using palace laparoscopy operation with 2 year complete follow-up records were selected as the study objects. Natural pregnancy rate after operation was analyzed. They were divided into pregnancy group and non-pregnancy group according to natural pregnancy or not after operation. The main factors influencing the pregnancy rate after operation were aimed to find out. Results Among the 93 cases of patients, there were 36 cases of natural pregnancy within 2 years after palace laparoscopy operation, and the total natural pregnancy rate was 38.71%(36/93). The total natural pregnancy rate within 6 months was 30.11%(28/93).There were 6 cases of the total natural pregnancy rate within 7-12 months after operation.The cumulative natural pregnancy rate was 36.56%within 1 year after operation, which was close to total pregnancy rate.There were 2 cases of the total natural pregnancy rate within 13-24 months after operation.Pregnancy rate 1 year after operation was decreased significantly (P<0.05). In the relevant influencing factors, history of infertility, abortion, history of pelvic surgery and pelvic inflammatory disease, combined pelvic endometriosis, moderate and severe pelvic adhesion 7 factors were significant impacted on the postoperative pregnancy rate of the patients (P<0.05). Conclusion Infertility diagnosis should be treated as soon as possible, once it is established. After the operation, doctors should provide the optimal and individualized follow-up conception for the patients with the infertility, the related history and the operation condition. For the patients, whose fallopian

    The goal of individualized and targeted treatment and precision medicine requires the assessment of potential therapeutic targets to direct treatment selection. The biomarkers used to direct precision medicine, often termed companion diagnostics, for highly targeted drugs have thus far been almost entirely based on in vitro assay of biopsy material. Molecular imaging companion diagnostics offer a number of features complementary to those from in vitro assay, including the ability to measure the heterogeneity of each patient's cancer across the entire disease burden and to measure early changes in response to treatment. We discuss the use of molecular imaging methods as companion diagnostics for cancer therapy with the goal of predicting response to targeted therapy and measuring early (pharmacodynamic) response as an indication of whether the treatment has "hit" the target. We also discuss considerations for probe development for molecular imaging companion diagnostics, including both small-molecule probes and larger molecules such as labeled antibodies and related constructs. We then describe two examples where both predictive and pharmacodynamic molecular imaging markers have been tested in humans: endocrine therapy for breast cancer and human epidermal growth factor receptor type 2-targeted therapy. The review closes with a summary of the items needed to move molecular imaging companion diagnostics from early studies into multicenter trials and into the clinic.

    Only textbook to focus primarily on the topic of pitfalls in diagnostic radiology. Highlights the pitfalls in a comprehensive and systematic manner. Written by experts in different imaging modalities and subspecialties from reputable centers across the world. The practice of diagnostic radiology has become increasingly complex, with the use of numerous imaging modalities and division into many subspecialty areas. It is becoming ever more difficult for subspecialist radiologists, general radiologists, and residents to keep up with the advances that are occurring year on year, and this is particularly true for less familiar topics. Failure to appreciate imaging pitfalls often leads to diagnostic error and misinterpretation, and potential medicolegal problems. Diagnostic errors may be due to various factors such as inadequate imaging technique, imaging artifacts, failure to recognize normal structures or variants, lack of correlation with clinical and other imaging findings, and poor training or inexperience. Many, if not most, of these factors are potentially recognizable, preventable, or correctable. This textbook, written by experts from reputable centers across the world, systematically and comprehensively highlights the pitfalls that may occur in diagnostic radiology. Both pitfalls specific to different modalities and techniques and those specific to particular organ systems are described with the help of numerous high-quality illustrations. Recognition of these pitfalls is crucial in helping the practicing radiologist to achieve a more accurate diagnosis.

    his study was performed to investigate the effect of image enhancement of periapical radiographs according to the diagnostic task. Eighty digital intraoral radiographs were obtained from patients and classified into four groups according to the diagnostic tasks of dental caries, periodontal diseases, periapical lesions, and endodontic files. All images were enhanced differently by using five processing techniques. Three radiologists blindly compared the subjective image quality of the original images and the processed images using a 5-point scale. There were significant differences between the image quality of the processed images and that of the original images (P<0.01) in all the diagnostic task groups. Processing techniques showed significantly different efficacy according to the diagnostic task (P<0.01). Image enhancement affects the image quality differently depending on the diagnostic task. And the use of optimal parameters is important for each diagnostic task.

    Beamlet is instrumented extensively to monitor the performance of the overall laser system and many of its subsystems. Beam diagnostics, installed in key locations, are used to fully characterize the beam during its propagation through the multipass cavity and the laser`s output section. This article describes the diagnostics stations located on Beamlet and discusses the design, calibration, and performance of the Beamlet calorimeters. The authors used Nova`s diagnostics packages to develop the Beamlet design to determine beam energy, spatial profile, temporal profile, and other beam parameters. Technologic improvements within the last several years in controls, charge-coupled device (CCD) cameras, and fast oscilloscopes have allowed the authors to obtain more accurate measurements on the Beamlet laser system. They briefly cover some of these techniques, including a description of their LabVIEW based data acquisition system.

    Cytology in uropathological diagnostics is mainly performed for oncological purposes. The assessment of malignancy by urothelial cell morphology is therefore decisive; however, cytology is only sensitive enough to detect high-grade tumor cells and the different low-grade tumors cannot be reliably diagnosed. Thus, the four-tier classification system of cytological findings (i.e. negative, atypical cells but significance uncertain, suspicious and positive) refers to high-grade tumor cells only. Furthermore, for valid cytological diagnostics not only the cytological specimen but also clinical information on cystoscopy findings and, if applicable, a biopsy should be evaluated together. In difficult differential diagnostic settings, e.g. differentiation between reactive versus neoplastic atypia or difficult to access lesions in the upper urinary tract, additional fluorescence in situ hybridization of cytological preparations might be helpful. At the moment there are no indications for further immunocytology or additional biomarker tests.

    The hematologic evaluation of reptiles is an indispensable diagnostic tool in exotic veterinary practice. The diversity of reptile species, their characteristic physiologic features, and effects of intrinsic and extrinsic factors present unique challenges for accurate interpretation of the hemogram. Combining the clinical presentation with hematologic findings provides valuable information in the diagnosis and monitoring of disease and helps guide the clinician toward therapy and further diagnostic testing. This article outlines the normal and pathologic morphology of blood cells of reptile species. The specific comparative aspects of reptiles are emphasized, and structural and functional abnormalities in the reptilian hemogram are described.

    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

    The development and design of plasma diagnostics for the International Thermonuclear Experimental Reactor (ITER) present a formidable challenge for experimental plasma physicists. The large plasma size, the high central density and temperature and the very high thermal wall loadings provide new challenges for present measurement techniques and lead to a search for new methods. But the physics and control requirements for the long burn phase of the discharge, combined with very limited access to the plasma, constrained by the requirement for radiation shielding of the coils and sharing of access ports with heating and current drive power, remote manipulation, fueling and turn blanket modules, make for very difficult design choices. An initial attempt at these choices has been made by an international team of diagnostic physicists, gathering together in a series of three workshops during the ITER Conceptual Design Activity. This paper is based on that report and provides a summary of its most important points. To provide a background against which to place the diagnostic requirements and design concepts, the ITER device, its most important plasma properties and the proposed experimental program will be described. The specifications for the measurement of the plasma parameters and the proposed diagnostics for these measurements will then be addressed, followed by some examples of the design concepts that have been proposed. As a result of these design studies, it was clear that there were many uncertainties associated with these concepts, particularly because of the nuclear radiation environment, so that a Research and Development Program for diagnostic hardware was established. It will also be briefly summarized.

    Background Gynecological laparoscopic surgery has the characteristics of small trauma and less pain and has been widely used in clinic. Patient controlled intravenous analgesia(PCIA)is often used for post - operative analgesia after laparoscopic surgery. The analgesic effect is exact but it is a general analgesia with many adverse reactions. So it is of great signifi-cance to seek a perfect analgesic method with less adverse reactions. Objective To evaluate the effect of local infiltration of ropiv-acaine on postoperative analgesia in patients underwent gynecologic laparoscopy. Methods 60 patients with ovarian lesions admit-ted to Beijing Obstetrics and Gynecology Hospital,Capital Medical University from November 2011 to June 2012 were select-ed. All the patients were scheduled for gynecologic laparoscopy. The patients were randomly divided into research group and control group with each group 30 cases. In the research group,local infiltration of 0. 4% ropivacaine was performed,and 10 ml(40 mg)was injected on the navel incision while 5 ml(20 mg)was injected on the unilateral incision above the Mcburney′ s point. The two groups of patients both received PCIA with sufentanil after operation. The operation time and bleeding volume were recorded,and the score of visual analogue scale(VAS)at 2 h,4 h,6 h and 24 h,Ramsay sedation score and BCS comfort level were also recorded. The consumption of sufentanil within 24 h after operation,the number of successfully delivered doses (D1 )and the number of attempts(D2 )within 24 h after operation were recorded. The D1 / D2 was calculated. The patients′ satis-faction and the adverse reactions were also recorded. Results The operation time and bleeding volume between the two groups showed no statistically significant difference(P > 0. 05). VSA score at different time,Ramsay sedation score showed statistical-ly significant differences between the two groups(P 0. 05). Compared with the control group,the sufentanil used in PCIA

That is why we have assessed BSABS items on a sample of 243 consecutive admissions to the Department of Psychiatry at the RWTH University, Aachen, and 79 psychologically healthy persons. Then, a cluster analysis was calculated to identify the empirical item-grouping. Five well-interpretable BSABS subsyndromes were found. In addition, uni- and multivariate analyses were computed to evaluate the diagnostic validity of these subsyndromes. We were able to show that every BSABS subsyndrome separates at least schizophrenic, organic mental and affective disorders from personality, neurotic and substance-induced disorders, as well as from psychological health. Furthermore, the subsyndrome "information processing disturbances" differentiates between schizophrenic and organic mental disorders, on the one hand, and affective disorders, on the other, and additionally, the subsyndrome "interpersonal irritation" between schizophrenics and all other persons examined.

    Vasculitis is characterized by inflammation and necrosis of blood vessels walls. It represents a heterogeneous group of conditions, whose etiopathogenic mechanisms remain unclear. Although uncommon, with an annual incidence of 40-54 cases per 1.000.000 persons, this is an important cause of multiorganic dysfunction and premature mortality. Depending on the affected vessels, it can cause diverse clinical presentations, which makes difficult its recognition. It is therefore a challenge for any clinician. This paper reviews the diagnostic and therapeutic advances of the most common forms of vasculitis, in order to optimize the approach and management of this clinical entity. We have conducted a search in Medline database on articles written in English, published for the last 10 years using the keywords: vasculitis, epidemiology, classification, diagnosis and treatment. To minimize the impact of vasculitis it is essential an early diagnosis, allowing a timely institution of the appropriate treatment. The diagnosis depends on the integration of clinical, laboratory, imaging and histopathologic data. According to the clinical condition, it may be indicated the removal of the offending antigen, the treatment of the underlying disease or specific treatment of the primary vasculitis. The introduction of immunosuppressive therapy with glucocorticoids and cyclophosphamide has revolutionized the prognosis of these patients but, despite its efficacy, it is associated with frequent relapses and significant toxicity. The study of the pathogenesis has been providing more effective and safer diagnostic and therapeutic options, for example B-cell depleting agents, but additional studies are needed to confirm the potential of these alternatives.

    Full Text Available Malignant catarrhal fever (MCF is a frequently fatal disease, primarily of ruminants, caused by a group of gammaherpesviruses. Due to complexities of pathogenesis and epidemiology in various species, which are either clinically-susceptible or reservoir hosts, veterinary clinicians face significant challenges in laboratory diagnostics. The recent development of specific assays for viral DNA and antibodies has expanded and improved the inventory of laboratory tests and opened new opportunities for use of MCF diagnostics. Issues related to understanding and implementing appropriate assays for specific diagnostic needs must be addressed in order to take advantage of molecular diagnostics in the laboratory.

    We established and validated diagnostic criteria for pityriasis rosea and Gianotti-Crosti syndrome. In this paper, we compare and contrast both diagnostic criteria to formulate a protocol in establishing diagnostic criteria for other dermatological diseases. The diagnostic criteria are similar in employing clear dividing lines and conjunctions ('and/or') to assure high reliability. Both sets of criteria should be applicable for all ethnic groups. Spontaneous remission is not included, so diagnosis is not delayed while waiting for disease remission. Laboratory investigations are not enlisted, so that the criteria can be used in medical care systems in different parts of the world. The diagnostic criteria are different in that pathognomonic clinical manifestations exist for pityriasis rosea, such as the herald patch and the orientation of lesions along the lines of skin cleavages. These features, however, score low for sensitivity. These specific manifestations are not seen in Gianotti-Crosti syndrome. Such differences led to different categorisation of clinical features. Atypical variants are more common for pityriasis rosea. The diagnostic criteria for pityriasis rosea therefore do not include a list of differential diagnoses, while diagnostic criteria for Gianotti-Crosti syndrome do. Using this comparison, we constructed a protocol to establish diagnostic criteria for other skin diseases. We advocate the need to justify the establishment of diagnostic criteria, that multiple diagnostic criteria for the same disease should be avoided, that diagnostic criteria should be compatible with the disease classification if applicable, and that the scope should be well-delineated with regard to clinical variants. We outline the need for validation studies to assess the criteria-related validity, test-retest intra-clinician reliability, and inter-clinician reliability. We emphasise that the establishment of diagnostic criteria should not be a generic process. We also

    Taking a careful history is vital for the evaluation of dysphagia. The history will yield the likely underlying pathophysiologic process and anatomic site of the problem in most patients, and is crucial for determining whether subsequently detected radiographic or endoscopic 'anomalies' are relevant or incidental. Although the symptoms of pharyngeal dysphagia can be multiple and varied, the typical features of neurogenic pharyngeal dysphagia are highly specific, and can accurately distinguish pharyngeal from esophageal disorders. The history will also dictate whether the next diagnostic procedure should be endoscopy, a barium swallow or esophageal manometry. In some difficult cases, all three diagnostic techniques may need to be performed to establish an accurate diagnosis. Stroke is the most common cause of pharyngeal dysphagia. A videoradiographic swallow study is vital in such cases to determine the extent and timing of aspiration and the severity and mechanics of dysfunction as a prelude to therapy.

    Full Text Available Medical diagnosis has been greatly improved thanks to the development of new techniques capable of performing very sensitive detection and quantifying certain parameters. These parameters can be correlated with the presence of specific molecules and their quantity. Unfortunately, these techniques are demanding, expensive, and often complicated. On the other side, progress in other fields of science and technology has contributed to the rapid growth of nanotechnology. Although being an emerging discipline, nanotechnology has raised huge interest and expectations. Most of the enthusiasm comes from new possibilities and properties of nanomaterials. Biosensors (simple, robust, sensitive, cost-effective combined with nanomaterials, also called nanobiosensors, are serving as bridge between advanced detection/diagnostics and daily/routine tests. Here we review some of the latest applications of nanobiosensors in diagnostics field.

    Binary optics, where the optical element can be fabricated on a thin glass plate with micro-ion-etching film layer, has been widely applied in recent years. A novel optical scanning system for gene disease diagnostics described in this paper has four kinds of optical devices, including beam splitters, an array lens, an array filter and detection arrays. A software was developed to design the binary optics system using an iterative method. Two beam splitters were designed and fabricated, which can divide a beam into a 9×9 array or into a 13×13 array. The beam splitters have good diffraction efficiencies (>70%) and an even energy distribution. The gene disease diagnostic system is a portable biochip and binary optics technology. The binary optical devices in the non-confocal scanning system can raise the fluorescence detection sensitivity of the micro-array hybrid biochip.

    In this paper, a novel approach to modeling and diagnosing the cardiovascular system is introduced. A model exhibits a subset of the dynamics of the cardiovascular behavior of an individual by using a recurrent artificial neural network. Potentially, a model will be incorporated into a cardiovascular diagnostic system. This approach is unique in that each cardiovascular model is developed from physiological measurements of an individual. Any differences between the modeled variables and the variables of an individual at a given time are used for diagnosis. This approach also exploits sensor fusion to optimize the utilization of biomedical sensors. The advantage of sensor fusion has been demonstrated in applications including control and diagnostics of mechanical and chemical processes.

    Blistering distal dactylitis is a distinct clinical entity, generally due to S. pyogenes, unfrequently reported. Characteristically, blistering distal dactylitis is described as a localized infection involving the distal phalanx of the digits, and it usually presents as a fluid-filled blister. Between October 2009 and June 2014, 69 children (median age: 60 months, extremes: 0,6-176) were enrolled. The sensitivity of GAS rapid antigen detection test was 97 % (CI 95 %: 83-100 %), the specificity was 76 % (CI 95 %: 60-89 %), the negative predictive value was 97 % (CI 95 %: 83-100 %), and the positive predictive value 76 % (CI 95 %: 60-89 %). All patients with a positive GAS rapid antigen test were treated with antibiotics (amoxicillin essentially) and cured without surgery.
