The aim of this study was to evaluate ileal J-pouch interposition as a neorectum between the anal canal and the remaining colon in comparison to coloanal anastomosis and transverse coloplasty. Methods: Twelve dogs, weighing 23-27 kg, were divided into three groups. After laparotomy, the volume of the primary rectum was measured so that it could be compared with that of the neorectum at the end of the study. After rectal resection in Group A, the colon was directly anastomosed to the anus. In Group B, a 5-cm longitudinal incision was made 2 cm proximal to the anastomosis and was sutured transversely (coloplasty). In Group C, a 5-cm ileal J-pouch was interposed between the colon and anus. After 8 weeks, the neorectum was evaluated for volume, radiology, and pathology. Results: All the samples were alive until the end of the study. The healing of the anastomotic lines was acceptable (pathologically) in all. The mean volume expansion was 20.9% in Group A, 21.7% in Group B, and 118.2% in Group C, with the latter being significantly higher than that of the other groups (P=0.03). Colon J-pouch and coloplasty after proctectomy in some situations have not been performable. This study evaluated the performance of ileal J-pouch interposition. Conclusion: This study showed that ileal J-pouch interposition might produce an acceptable reservoir function and that it seems feasible and safe in selected cases. PMID:24644380

    Full Text Available Aim. Single-access laparoscopic surgery (SALS can be effective for benign and malignant diseases of the ileum in both the elective and urgent setting. Methods. Ten consecutive, nonselected patients with ileal disease requiring surgery over a twelve month period were included. All had a preoperative abdominopelvic computerized tomogram. Peritoneal access was achieved via a single transumbilical incision and a “surgical glove port” utilized as our preferred access device. With the pneumoperitoneum established, the relevant ileal loop was located using standard rigid instruments. For ileal resection, anastomosis, or enterotomy, the site of pathology was delivered and addressed extracorporeally. Result. The median (range age of the patients was 42.5 (22–78 years, and the median body mass index was 22 (20.2–28 kg/m2. Procedures included tru-cut biopsy of an ileal mesenteric mass, loop ileostomy and ileotomy for impacted gallstone extraction as well as ileal (=3 and ileocaecal resection (=4. Mean (range incision length was 2.5 (2–5 cm. All convalescences were uncomplicated. Conclusions. These preliminary results show that SALS is an efficient and safe modality for the surgical management of ileal disease with all the advantages of minimal access surgery and without requiring a significant increase in theatre resource or cost or incurring extra patient morbidity.

    Complications from a Meckel's diverticulum include diverticulitis, bleeding, intussusception, bowel obstruction, a volvulus, a vesicodiverticular fistula, perforation or very rarely as a tumour. We report a case where a Meckel's diverticulum presented with a terminal ileal volvulus in a 32-year-old man without the presence of a typical vitelline band or axial torsion of the diverticulum causing the volvulus. It was successfully managed laparoscopically.

    Few studies have reported minimally invasive total proctocolectomy with ileal pouch-anal anastomosis (IPAA) for ulcerative colitis (UC) and familial adenomatous polyposis (FAP). We herein report a novel hand-assisted hybrid laparoscopic-robotic technique for patients with FAP and UC. Between February 2010 and March 2014, six patients underwent hand-assisted hybrid laparoscopic-robotic total proctocolectomy with IPAA. The abdominal colectomy was performed laparoscopically with hand assistance through a transverse suprapubic incision, also used to fashion the ileal pouch. The proctectomy was carried out with the da Vinci Surgical System. The IPAA was hand-sewn through a trans-anal approach. The procedure was complemented by a temporary diverting loop ileostomy. The mean hand-assisted laparoscopic surgery (HALS) time was 154.6 (±12.8) min whereas the mean robotic time was 93.6 (±8.1) min. In all cases, a nerve-sparing proctectomy was performed, and no conversion to traditional laparotomy was required. The mean postoperative hospital stay was 13.2 (±7.4) days. No anastomotic leakage was observed. To date, no autonomic neurological disorders have been observed with a mean of 5.8 (±1.3) bowel movements per day. The hand-assisted hybrid laparoscopic-robotic approach to total proctocolectomy with IPAA has not been previously described. Our report shows the feasibility of this hybrid approach, which surpasses most of the limitations of pure laparoscopic and robotic techniques. Further experience is necessary to refine the technique and fully assess its potential advantages.

    Emerging evidence suggests that a laparoscopic approach to colorectal procedures generates fewer adhesions. Even though laparoscopic ileal pouch-anal anastomosis (IPAA) is a lengthy procedure, the prospect of fewer adhesions may justify this approach. The aim of this study was to assess abdominal and adnexal adhesion formation following laparoscopic versus open IPAA in patients with ulcerative colitis. A diagnostic laparoscopy was performed at time of ileostomy closure. All abdominal quadrants and the pelvis were video recorded systematically and graded offline. The incisional adhesion score (IAS; range 0-6) and total abdominal adhesion score (TAS; range 0-10) were calculated, based on the grade and extent of adhesions. Adnexal adhesions were classified by the American Fertility Society (AFS) adhesion score. A total of 43 patients consented to participate, of whom 40 could be included in the study (laparoscopic 28, open 12). Median age was 38 (range 20-61) years. There was no difference in age, sex, body mass index, American Society of Anesthesiologists grade and time to ileostomy closure between groups. The IAS was significantly lower after laparoscopic IPAA than following an open procedure: median (range) 0 (0-5) versus 4 (2-6) respectively (P = 0·004). The TAS was also significantly lower in the laparoscopic group: 2 (0-6) versus 8 (2-10) (P = 0·002). Applying the AFS score, women undergoing laparoscopic IPAA had a significantly lower mean(s.d.) prognostic classification score than those in the open group: 5·2(3·7) versus 20·0(5·6) (P = 0·023). Laparoscopic IPAA was associated with significantly fewer incisional, abdominal and adnexal adhesions in comparison with open IPAA. Copyright © 2011 British Journal of Surgery Society Ltd.

    Full Text Available Surgery for ulcerative colitis is a major and complex colorectal surgery. Laparoscopy benefits these patients with better outcomes in context of cosmesis, pain and early recovery, especially in young patients. For surgeons, it is a better tool for improving vision and magnification in deep cavities. This is not the simple extension of the laparoscopy training. Starting from preoperative preparation to post operative care there are wide variations as compared to open surgery. There are also many variations in steps of laparoscopic surgery. It involves left colon, right colon and rectal mobilisation, low division of rectum, pouch creation and anastomosis of pouch to rectum. Over many years after standardisation of this technique, it takes same operative time as open surgery at our centre. So we present our standardized technique of laparoscopic assisted restorative proctocolectomy and ileal pouch anal anastomosis (IPAA.

    mortalidade, factível cirurgicamente pela via laparoscópica e passível de ser ofertada como opção operatória ao tratamento da diabetes mellitus tipo 2.INTRODUCTION: There is an evidence that the best results in terms of resolution of diabetes in morbidly obese patients are achieved with bilio-pancreatic bypass, especially the duodenal switch. These operations are characterized by partial gastrectomy and the rapid transit of food into the distal ileum through derivation of a significant segment of small intestine. The idea of performing the technique presented here was based on these principles. METHOD: The procedures are usually performed laparoscopically, after establishment of a pneumoperitoneum at 12-15 mmHg and introduction of six trocars. The patient is initially positioned in 30° reverse Trendelenburg with the surgeon on the right side of the patient. The sleeve gastrectomy is performed using the anatomical distal trifurcation of the anterior vagus nerve as a reference. The devascularization of the greater curvature is performed and extends to the oesophagogastric junction. With an intra-gastric calibration tube of 20 mm positioned along the lesser curvature, gastric resection starts at the proximal antrum with linear stapler up to oesophagogastric angle. An invaginating running suture is also performed. To perform the ileal interposition in the proximal jejunum, it is divided 20-30 cm distally with a 45-mm linear stapler. The cecum is identified and the distal ileum transected 30cm proximal to the ileocecal valve. A 170 to 200 cm of ileum was measured proximally along the anti-mesenteric border using a 10-cm marked atraumatic grasper, and transected with a 45-mm linear stapler. This segment of ileum is interposed in an isoperistaltic way into the proximal jejunum, previously divided. Next are perform three side-to-side enteroanastomosis. The first enteroanastomosis is the ileo-ileostomy, then the jejuno-ileostomy and finally, the ileo-jejunostomy. All three

    Familial adenomatous polyposis is a hereditary disease characterized by the presence of thousands of colonic adenomas, which, if untreated, invariably undergo malignant transformation. Because this disease manifests at a young age, the laparoscopic approach to perform surgery would be desirable due to its cosmetic benefits. We describe our experience with this procedure and review the literature on the topic. This is a case series of 15 patients who underwent restorative proctocolectomy with ileo-anal pouch anastomosis for familial adenomatous polyposis between 2000 and 2007. The salient operative steps are described. There were 9 males and 6 females, 32 to 52 years of age, with an average age of 44.8 years. The median body mass index was 21.5 (range, 17 to 28). Rectal cancer was already present in 4 patients at the time of diagnosis. The median operating time was 225 minutes. Mean blood loss was 60 mL, with none of the patients requiring perioperative blood transfusion. None of the surgeries required conversion to the open approach. Bowel function resumed on the second postoperative day in 12 patients and on the third postoperative day in 3 patients. The median hospital stay was 8 days. Postoperatively, there was no mortality and no serious morbidity. Laparoscopic restorative proctocolectomy with ileal pouch anal anastomosis is a feasible surgery for familial adenomatous polyposis, and considering its cosmetic benefit, is a desirable option for this group of predominantly young patients.

    To assess morbidity and functional consequences of laparoscopic cystectomy with ileal conduit urinary diversion: in neurologic patients. We reviewed the records of forty-two patients (ten men and thirty-two women) who underwent surgery between August 2007 and October 2013. The median age of the patient was 54 years old (range between 21-79 years). A laparoscopic cystectomy was performed followed by a short laparotomy to perform the ileal conduit urinary diversion. Records were reviewed to retrieve the indications and describe the postoperative and functional course. Patients and GPs were interviewed during phone calls to appreciate the quality of life by the PGII scale in order to assess the functional outcome. The operation was performed on 42 patients, of whom 18 had multiple sclerosis, nine a post-traumatic neurogenic bladder. Among the total population, 10 patients (23.81%) required a transfusion of at least one packed red blood cells (1-7). The overall rate of early complications was 35.71%. Belated complications were seen in 52.38% of the population. The median duration of hospital stay was 16 days (range between 9-70 days). The median follow up was 34 months (range between 1-76 months). For patients, the PGII scale rating had a median value of 6 (2-7). All referring physicians described a better functional status. The laparoscopic cystectomy can make postoperative course smoother for the neurological patients. However, the surgeon must weigh individually the benefit of performing the operation.

  17. Interposition vein cuffs.

    Science.gov (United States)

    Harris, P; Da Silva, T; How, T

    1996-01-01

    A vein cuff interposed at the distal anastomosis between a prosthetic vascular graft and a recipient infrageniculate artery improves the chances of continued patency of the graft, at least in the short and medium term. The mode of effect appears to be suppression or modification of anastomotic myointimal hyperplasia (MIH). In the event of graft failure the recipient artery and run-off vessels remain free from MIH and their patency is preserved thereby improving the prospects for further vascular reconstruction and limb salvage. The mechanisms by which interposition vein cuffs might modulate MIH are reviewed. Experimental evidence is described to show that the geometry of a cuffed anastomosis promotes a characteristic haemodynamic flow structure with a stable vortex. It is suggested that this vortex exerts greater shear stress upon the wall of the artery than the normal laminar flow observed in conventional anastomoses. High shear stress is known to inhibit MIH.

    Full Text Available Abstract Background There is still confusion and controversy over the diagnosis and optimal surgical treatment of non traumatic terminal ileal perforation-a cause of obscure peritonitis. Methods This study was a prospective study aimed at evaluating the clinical profile, etiology and optimal surgical management of patients with nontraumatic terminal ileal perforation. Results There were 79 cases of nontraumatic terminal ileal perforation; the causes for perforation were enteric fever(62%, nonspecific inflammation(26%, obstruction(6%, tuberculosis(4% and radiation enteritis (1%. Simple closure of the perforation (49% and end to side ileotransverse anastomosis(42% were the mainstay of the surgical management. Conclusion Terminal ileal perforation should be suspected in all cases of peritonitis especially in developing countries and surgical treatment should be optimized taking various accounts like etiology, delay in surgery and operative findings into consideration to reduce the incidence of deadly complications like fecal fistula.

    2018-03-01

    Post-hysterectomy vesicovaginal fistula (VVF) is rare. In addition to conventional abdominal and vaginal approaches, robotic-assisted VVF repairs have recently been described. We present a case of an extravesical, robotic-assisted VVF repair, without placement of an interposition graft performed in a Canadian teaching center. A 51-year-old woman presented with urinary incontinence 5 days after laparoscopic hysterectomy. Computed tomography cystogram, cystoscopy, and methylene blue dye test, confirmed a VVF above the bladder trigone. The patient underwent a robotic-assisted VVF repair 3 months after presentation, without complication. An abdominal, extravesical approach was used. Operative time was 116 min and repeat CT cystogram showed no evidence of persistent. We have demonstrated that a VVF repair, using a robotic-assisted, extravesical approach without interposition graft placement, can be safe, less invasive and have a successful outcome at 1 year of follow-up.

    2011-01-01

    Anomalies of the gallbladder position in the biliary tract are rare, but they could be very dangerous during cholecystectomy. A 48-year-old man presented with a 2-week history of intermittent epigastric pain, scleral jaundice and elevation of liver function tests. After a magnetic resonance cholangiogram and an endoscopic retrograde cholangiogram with sphincterotomy, he was submitted to laparoscopic cholecystectomy, the conversion to laparotomy was decided for the suspect of gallbladder interposition. The anatomical anomaly was confirmed and a Roux-en-Y hepaticojejunostomy was executed, with end-to-side anastomosis between the confluence of the hepatic ducts and the fourth loop of jejunum, on a biliary stent. This catheter was removed in the tenth postoperative day; after cholangiography and CT abdominal scan the patient was discharged, without complications. The gallbladder interposition is a rare malformation which seems to arise from an embryonic anomaly occurring between the 4th and the 5th week and whose potential causes have not been detected. A similar outcome could be also determined by a Mirizzi syndrome, but in our case it is excluded because intra-operatively there was no inflammatory reaction that could justify the presence of a fistula between the gallbladder and the common hepatic duct. Once the gallbladder interposition is found, the surgical treatment consists in removing the gallbladder itself and the corresponding part of the common hepatic duct. The reconstruction is carried out by a Roux-en-Y hepaticojejunostomy with anastomosis at the hepatic hilum, positioning a biliary stent.

This case not only highlights the importance of routine ileoscopy but also the successful use of chemotherapy in a disease for which the optimal treatment modality has not been well characterized.

    Ten patients with severe postgastrectomy-postvagotomy symptoms, all of whom had the features of vasomotor dumping, underwent gastric emptying studies, using a 300 milliliter meal of 15 per cent dextrose labeled with 99mTc-sulphur colloid. Studies were repeated two to 11 months following remedial operative treatment, using a 12.5 to 15.0 centimeter isoperistaltic jejunal interposition. Preoperatively, all patients had rapid gastric emptying with a typical biphasic pattern. Following isoperistaltic interposition, the rate of gastric emptying was similar to that found in control patients. Gastric emptying reverted to a more normal pattern but, as in the preoperative studies, was best described by a double exponential function, consisting of slow and fast components. Analysis of these particular functions suggests the manner in which isoperistaltic interposition modified the underlying disorder of gastric motility.

    For patients with hallux rigidus seeking a motion-sparing procedure, interposition arthroplasty is an alternative to fusion. The purpose of this study was to report patient outcomes after interpositional arthroplasty for hallux rigidus. All patients undergoing interpositional arthroplasty at our institution from 2001 to 2014 were identified and a retrospective chart review was performed. Follow-up was conducted through a telephone survey to obtain survivorship, satisfaction, and functional scores. Survivorship of the interpositional arthroplasty procedure was defined as no subsequent surgery on the hallux after the index procedure. Patients were excluded for incomplete records. Complications were recorded. From 2001 to 2014, 183 patients were identified. Of these, 14 were excluded for incomplete data, leaving 169 patients. Of these, 133 had an average follow-up of 62.2 months (range, 24.3 months to 151.2 months). The overall failure rate was 3.8% (5/133). Patient-reported outcome was rated as excellent in 65.4% (87/133) or good in 24.1% (32/133) of patients and fair or poor in 10.5% (14/133) of patients. Of 133 patients, 101 (76%) were able to return to fashionable or regular footwear. The infection rate was 1.5% (2/133). Patient-reported cock-up deformity of the first metatarsophalangeal joint (MTPJ) occurred in 4.5% (6/133) of patients. In addition, 17.3% (23/133) of patients reported metatarsalgia of the second or third MTPJ at the time of final follow-up, and there was no significant difference between interposition types ( P = .441). Interpositional arthroplasty for hallux rigidus was found to have excellent or good results in most patients at a mean follow-up of 62.2 months. Level IV, retrospective case series.

    To describe the laparoscopic approach for uretero-ileal anastomosis strictures and to analyse our long term series. A retrospective review was performed evaluating our series of patients with benign ureteroileal anastomosis strictures treated laparoscopically from 2011 to 2017. Demographics and perioperative data were obtained and analyzed. Complications were described with the Clavien-Dindo classification. The surgical technique was described and a literature review was performed. Eleven procedures were performed in ten patients. Mean blood loss was 180 ml. All the operations were performed laparoscopically without conversion. Mean hospital stay was 10 days (4-23). Early complications were Clavien-Dindo I y II: Two cases of limited anastomosis leakage, one lymphorrea, one paralitic ileum and one accidental descent of the ureteral catheter. Mean follow-up was 56 months (12-179) No late complications have been described. Based on our series with 5 year follow up, the laparoscopic approach for uretero-ileal anastomosis strictures is feasible and safe.

    Full Text Available Anorectal malformation is a common anomaly in neonates. Although colorectal perforations have been reported as a complication, ileal perforation is rarely encountered. This is a report of a 2-day-old boy presenting with a low anorectal malformation, complicated with ileal perforation, necessitating laparotomy and ileal repair. Anoplasty was done for the low anomaly. Early presentation and prompt treatment of anorectal malformations is important to prevent such potential life threatening complication.

    Full Text Available Abstract Background Laparoscopic gastrectomy is a new and technically challenging surgical procedure with potential benefit. The objective of this study was to investigate clinical and para-clinical consequences following Roux-en-Y and Jejunal Loop interposition reconstructive techniques for subtotal gastrectomy using laparoscopic assisted surgery. Results Following resection of the stomach attachments through a laparoscopic approach, stomach was removed and reconstruction was performed with either standard Roux-en-Y (n = 5 or Jejunal Loop interposition (n = 5 methods. Weight changes were monitored on a daily basis and blood samples were collected on Days 0, 7 and 21 post surgery. A fecal sample was collected on Day 28 after surgery to evaluate fat content. One month post surgery, positive contrast radiography was conducted at 5, 10, 20, 40, 60 and 90 minutes after oral administration of barium sulfate, to evaluate the postoperative complications. There was a gradual decline in body weight in both experimental groups after surgery (P  0.05. Fecal fat content increased in the Roux-en-Y compared to the Jejunal loop interposition technique (P  0.05. Conclusion Roux-en-Y and Jejunal loop interposition techniques might be considered as suitable approaches for reconstructing gastro-intestinal tract following gastrectomy in dogs. The results of this study warrant further investigation with a larger number of animals.

    Full Text Available Background. Radical cystectomy remains the golden standard for treatment of muscle invasive bladder cancer. Objective: to duplicate with highest accuracy the open radical cystectomy procedure, which we successfully utilized earlier in our clinic, in the of laparoscopic conditions in order to preserve the advantages of minimally invasive procedures and retain the reliability of the tried and tested open surgery.Materials and methods. In the report were included 35 patients (27 men and 8 women with bladder cancer, who underwent laparoscopic radical cystectomy in Volgograd Regional Center of Urology and Nephrology between April 2013 and March 2016. Only the patients who had been submitted to full intracorporal ileal conduits were included.Results. The mean operative time was 378 minutes, the mean blood loss was 285 millilitres, the mean length of hospital stay was 12.4 days, only 20 % of patients required the narcotic anesthetics. The postoperative complication rate was 11.4 %. However, the majority of the patients were successfully treated with minimally invasive procedures. Generally, our results were similar to other reported studies.Conclusion. Laparoscopic radical cystectomy is a safe and efficient modality of treatment of bladder cancer. However, it needs more procedures and longer observation period to establish laparoscopic radical cystectomy as an alternative to open radical cystectomy.

    Conclusion: Glenohumeral contact pressure is significantly improved with interposition of allograft at time zero compared to an arthritic state. Our findings suggest that concentric reaming did not differ from the arthritic model when compared to normal. These findings favor the use of allograft for interposition as a potential treatment option in patients with glenoid wear.

    2013-10-01

    The hypoglossal-facial-anastomosis is the most often applied procedure for the reanimation of a long lasting peripheral facial nerve paralysis. The use of an interposition graft and its end-to-side anastomosis to the hypoglossal nerve allows the preservation of the tongue function and also requires two anastomosis sites and a free second donor nerve. We describe the modified technique of the hypoglossal-facial-jump-anastomosis without an interposition and present the first results. Retrospective case study. We performed the facial nerve reconstruction in five patients. The indication for the surgery was a long-standing facial paralysis with preserved portion distal to geniculate ganglion, absent voluntary activity in the needle facial electromyography, and an intact bilateral hypoglossal nerve. Following mastoidectomy, the facial nerve was mobilized in the fallopian canal down to its bifurcation in the parotid gland and cut in its tympanic portion distal to the lesion. Then, a tensionless end-to-side suture to the hypoglossal nerve was performed. The facial function was monitored up to 16 months postoperatively. The reconstruction technique succeeded in all patients: The facial function improved within the average time period of 10 months to the House-Brackmann score 3. This modified technique of the hypoglossal-facial reanimation is a valid method with good clinical results, especially in cases of a preserved intramastoidal facial nerve. Level 4.

    Full Text Available BackgroundThis study has been conducted with the aim of evaluating modified T-plate interpositional arthroplasty.MethodsA prospective comparative study in patients admitted with temporomandibular joint ankylosis. Ankylotic temporomandibular joint arthroplasty included condylectomy gap arthroplasty in 7, temporalis muscle flap interpositional arthroplasty in 8, and modified T-plate interpositional arthroplasty in 13 cases. The patients were followed for three years. Collected data were tabulated and subjected to Fisher's exact test, chi-square test and probability estimation.ResultsA significant increase in interincisal distance of 32 mm was seen in 12 (92.31% patients in the T-plate interposition group, in 2 (25% cases of the temporalis muscle flap interposition group, and in 1 case (14.28% of the condylectomy group at 12, 24, and 36 months. Re-ankylosis was observed in 1 case (9.69% of the T-plate interposition group, while as it was observed in 4 (50% cases in the temporalis muscle flap interposition group and 4 (57.14% cases in the condylectomy group, and these differences were statistically significant.ConclusionsOur clinical experience with the use of the T-plate over the past 5 years has been encouraging, and our physiotherapy technique is quite simple. Even illiterate parents can assess it easily. Hence, we recommend this easy technique that does not damage the temporalis muscle for the management of temporomandibular joint ankylosis.

  1. Robotic Assisted Radical Cystoprostatectomy and Intracorporeal Ileal Conduit Urinary Diversion for a Kidney Transplant Recipient

    Directory of Open Access Journals (Sweden)

    Peter A. Caputo

    Full Text Available ABSTRACT Introduction and Objectives: Robotic assisted radical cystectomy (RARC is an alternative to open radical cystectomy. As experience is gained with the RARC approach the technique is being applied to more complex surgical cases. We describe here our technique for RARC with intracorporeal ileal conduit urinary diversion for a renal transplant recipient. Materials and Methods: The patient is a 60-year old man with high-grade muscle invasive bladder cancer. He has a history of renal failure due to polycystic kidney disease and received a deceased donor renal transplant in 2008. His hospital course at time of transplant was complicated by low-level BK virus viremia. Interestingly his trans-urethral bladder tumor resection specimen at time of bladder cancer diagnosis stained positive for SV40. His native kidneys were anuric so bilateral laparoscopic nephrectomy was performed in a staged fashion 2 weeks prior to RARC. Our surgical technique utilizes 6 trocars, of note a 12-mm assistant trocar is placed 1 cm superior to the pubic symphysis, and this trocar is solely used to pass a laparoscopic stapler to facilitate the excision of the ileal segment and the stapled enteric anastomosis. Surgical steps include: identification of native ureters bilaterally (removed en bloc with the bladder specimen; identification of the transplanted ureter at the right bladder dome; posterior bladder and prostate dissection along Denonvilliers’ fascia; development of the space of Retzius; ligation and transection of the bladder and prostate vascular bundles; apical prostate dissection and transection of urethra; left pelvic lymphadenectomy; ilium resection for creation of the ileal conduit; stapled enteric anastomosis; ureteroileal anastomosis; maturation of the ileal conduit stoma. Results: The surgery had no intraoperative complications. Operative time was 443 minutes (7.4 hours. Estimated blood loss was 250 cc. Length of hospital stay was 5 days. The patient

    Intra-articular membranous interposition was detected by MRI in the hip joint with residual subluxation of a girl aged 5 years 10 months. This structure, which had low signal intensity on both T1- and T2-weighted images, separated the femoral head from the acetabulum. Histological examination revealed chondrometaplasia, which suggested that this interposition might be transformed to a surface cartilaginous tissue of the secondary acetabulum often observed in residual subluxation of the hip.

    Full Text Available Objective: To compare audiometric results between the standard total ossicular replacement prosthesis (TORP-S and a new fat interposition total ossicular replacement prosthesis (TORP-F in pediatric and adult patients and to assess the complication and the undesirable outcome. Study design: This is a retrospective study. Methods: This study included 104 patients who had undergone titanium implants with TORP-F and 54 patients who had undergone the procedure with TORP-S between 2008 and 2013 in our tertiary care centers. The new technique consists of interposing a fat graft between the 4 legs of the universal titanium prosthesis (Medtronic Xomed Inc, Jacksonville, FL, USA to provide a more stable TORP in the ovale window niche. Normally, this prosthesis is designed to fit on the stapes’ head as a partial ossicular replacement prosthesis. Results: The postoperative air-bone gap less than 25 dB for the combined cohort was 69.2% and 41.7% for the TORP-F and the TORP-S groups, respectively. The mean follow-up was 17 months postoperatively. By stratifying data, the pediatric cohort shows 56.5% in the TORP-F group (n = 52 compared with 40% in the TORP-S group (n = 29. However, the adult cohort shows 79.3% in the TORP-F group (n = 52 compared with 43.75% in the TORP-S group (n = 25. These improvements in hearing were statistically significant. There were no statistically significant differences in the speech discrimination scores. The only undesirable outcome that was statistically different between the 2 groups was the prosthesis displacement: 7% in the TORP-F group compared with 19% in the TORP-S group ( P  = .03. Conclusions: The interposition of a fat graft between the legs of the titanium implants (TORP-F provides superior hearing results compared with a standard procedure (TORP-S in pediatric and adult populations because of its better stability in the oval window niche.

  7. Laparoscopic herniorrhaphy.

    Swanstrom, L L

    1996-06-01

    There is little doubt that laparoscopic herniorrhaphy has assumed a place in the pantheon of hernia repair. There is also little doubt that further work needs to be done to determine the exact role that laparoscopic hernia repair should play in the surgical armamentarium. Hernias have been surgically treated since the early Greeks. In contrast, laparoscopic hernia repair has a history of only 6 years. Even within that short time, laparoscopic hernia repair techniques have not remained unchanged. This is obviously a technique in evolution, as indicated by the abandonment of early repairs ("plug and mesh" and IPOM) and the gradual gain in pre-eminence of the TEP repair. During the same time frame, surgery itself has evolved into a discipline more concerned with cost-effectiveness, outcomes, and "consumer acceptance." Confluence of these two developments has led to a situation in which traditional concerns regarding surgical procedures (i.e., recurrence rates or complication rates) assume less of a role than cost-effectiveness, learnability, marketability, and medical-legal considerations. No surgeon, whether practicing in a academic setting or a private practice, is exempt from these pressures. Laparoscopic hernia repair therefore seems to fit into a very specialized niche. In our community, the majority of general surgeons are only too happy to not do laparoscopic hernia repairs. On the other hand, in our experience, certain indications do seem to cry out for a laparoscopic approach. At our own center we have found that laparoscopic repairs can indeed be effective, and even cost-effective, under specific circumstances. These include completing a minimal learning curve, utilizing the properitoneal approach, minimizing the use of reusable instruments, using dissecting balloons as a time-saving device, and very specific patient selection criteria. At present these include patients with bilateral inguinal hernias on clinical examination, patients with recurrent

    Neonatal intestinal volvulus in the absence of malrotation is a rare occurrence and rarer still is the intestinal volvulus in absence of any other predisposing factors. Primary segmental volvulus in neonates is very rare entity, which can have catastrophic outcome if not intervened at appropriate time. We report two such cases, which were preoperatively diagnosed as ileal atresia and intraoperatively revealed to be primary segmental volvulus of the ileum. PMID:26023426

    2016-02-01

    Full Text Available Abstract The present report describes a case where typical findings of traumatic glenohumeral interposition of rotator cuff stumps were surgically confirmed. This condition is a rare complication of shoulder trauma. Generally, it occurs in high-energy trauma, frequently in association with glenohumeral joint dislocation. Radiography demonstrated increased joint space, internal rotation of the humerus and coracoid process fracture. In addition to the mentioned findings, magnetic resonance imaging showed massive rotator cuff tear with interposition of the supraspinatus, infraspinatus and subscapularis stumps within the glenohumeral joint. Surgical treatment was performed confirming the injury and the rotator cuff stumps interposition. It is important that radiologists and orthopedic surgeons become familiar with this entity which, because of its rarity, might be neglected in cases of shoulder trauma.

    2004-01-01

    Restorative proctocolectomy and ileal pouch (IP) has become an established surgery for patients with chronic ulcerative colitis and poliposis syndromes. The authors report the results of 8-year experience of restorative proctocolectomy and IP. Chart review was performed for 51 patients undergoing IP from 1994 through 2002. Preoperative histopathologic diagnoses were ulcerative colitis (n=39), poliposis syndromes (n=10), 2 Crohn diseases and 1 patient with colorectal cancer and extended resection. Information was obtained regarding patient demographics, type and duration of diseases, previous operations, and indications for surgery. Early (within 30 days after surgery) and late complications were noted. Follow-up included an annual function, physical examination, and biopsies of the pouch and anal transitional zone when were indicated. Of the 51 patients (24 women) with mean follow-up time of 44,5 months (range 12 -108 months), histopathologic diagnoses of ulcerative colitis were changed for Crohn's disease in 2 patients. The overall mortality rate was 2% (1 patient) one death was related to perineal sepsis 45 months after ileal pouch. The overall morbidity rate was 65% (73 complications in 33 patients; early 39%; late 49%) the mean hospitalary stance was 8, 9 days (range 6-25 days). Small bowel obstruction, septic complication and reoperation rates were 36%, 22% and 26%, respectively. The most frequent late complication was pouchitis (31,8%). The ileal pouch was removed in 1 patient, and it is functional in 50 (98%). There was a satisfactory index with 82% with excellent-good results, and 16% and 2% with regular and bad results. Restorative proctocolectomy with an IP is a safe procedure, with low mortality and major morbidity rates. Although total morbidity rate is appreciable, functional results generally are good and patient satisfaction is acceptable

    Taenia spp. are flatworms of the class Cestoda, whose definitive hosts are humans and primates. Human infestation (taeniasis) results from the ingestion of raw meat contaminated with encysted larval tapeworms and is considered relatively harmless and mostly asymptomatic. Anemia is not recognized as a possible sign of taeniasis and taeniasis-induced hemorrhage is not described in medical books. Its therapy is based on anthelmintics such praziquantel, niclosamide or albendazole. Here we describe a case of acute ileal bleeding in an Italian man affected with both Taenia spp. infestation resistant to albendazole and Helicobacter pylori -associated duodenal ulcers.

    Traumatic interposition of a rotator cuff tendon in the glenohumeral joint without recognizable glenohumeral dislocation is an unusual complication after shoulder trauma. Here we report the clinical and imaging presentations of a 17-year-old man with trapped rotator cuff tendons in the glenohumeral joint after a bicycle accident. The possible trauma mechanism is also discussed.

    Interpositional arthroplasty is considered by many surgeons for the treatment of isolated medial compartment osteoarthritis of the knee. In this procedure, an interpositional spacer is inserted into the medial compartment of the joint with no bone resection and no mechanical fixation. Major problems such as implant dislocation, severe pain or need for revision have been reported post-operatively. In this study, the kinematics of a knee implanted with an interpositional spacer made of either polyurethane or cobalt-chrome during walking, stair ascent and squatting cycles have been predicted and compared to the normal knee using finite element analysis. In addition, articular cartilage stress histories have been examined to obtain distributions of cumulative stress, a measure of the likelihood of articular cartilage degeneration. The insertion of a polyurethane interpositional spacer in the medial side of the knee did not affect knee kinematics as compared to the normal knee, but caused an increase of articular cartilage cumulative contact stress exposures in the medial compartment of the joint. The knee implanted with the Co-Cr spacer exhibited similar trends in knee kinematics, however significantly different ranges of motion were observed during some periods of the activity cycles, specifically during the first half of the walking cycle where lower ranges of motion were predicted. In addition, higher articular cartilage cumulative contact stress exposures were observed in both compartments of the knee. In both cases, cumulative contact stress exposures of the tibial articular cartilage were more affected than those of the femoral articular cartilage. These results suggest implant material as an important parameter in the design phase of interpositional spacers.

    We report our results and short term follow up of transperitoneal laparoscopic pyeloplasty for pelvi-ureteric junction (PUJ) obstruction. We have prospectively maintained a database to document our initial experience of 54 laparoscopic pyeloplasty. All procedures were carried out by one surgeon through a transperitoneal approach. The data extends from April 2005 to September 2008 and reports operative time, blood loss, complications, hospital stay, short term follow-up on symptomatic and radiological outcome. Fifty-four procedures were performed during the study period. Mean patient age was 29 years. Mean operating time was 133 minutes (range 65-300 minutes), and mean blood loss was 45 ml (range 20-300 ml). No intra operative complication occurred. Neither blood transfusion nor conversion to open surgery was required. Postoperative mean hospital stay was 3.4 days (range 3-14 days). There were 3 anastomotic leakages; 2 in the immediate postoperative period and 1 following removal of stent. They all required percutaneous drainage and prolonged stenting. Overall 47 (87%) patients have symptomatic relief and resolution of obstruction on renogram. Four (7%) patients developed recurrence. Three (5.5%) patients had symptomatic relief but have a persistent obstructive renogram. Laparoscopic pyeloplasty is an effective alternative treatment for symptomatic pelvi-ureteric junction obstruction. The results appear comparable to open pyeloplasty with decreased postoperative morbidity.

    Full Text Available Purpose: To discuss the role and mechanism of action of soft tissue reinforcement interposition flaps (STRIFs in hypospadias repairs (reinforced hypospadiac urethroplasties. Materials and Methods: Between 2000-2005, 120 consecutive hypospadiacs (distal 85, mid 20, proximal 15, who underwent primary reinforced urethroplasties employing different types of STRIFs, were retrospectively analyzed. The STRIFs were highly vascular soft tissue pedicled flaps (devoid of epithelium interposed between neo-urethras and the covering skin to reinforce the neo-urethras against fistula formation. The STRIFs were harvested, without much donor site deformity, from: preputial skin, penile skin and scrotal skin by de-epithelialization. Those from Buck′s fascia, corpus spongiosum and tunica vaginalis are STRIFs without epithelium anyway, therefore do not need de-epithelialization. Redo urethroplasties and micropenises were not included. Seven patients were excluded because they had incomplete follow-up. The remaining 113 (distal 84, mid 17, proximal 12 were followed up for nine to 40 months for number, size, location, spontaneous closure and persistence of urethro-cutaneous fistula (UCF, and other complications with regard to the severity of hypospadias, method of neourethral re-construction, types of STRIFs employed and skin cover used. A total of 158 STRIFs and 124 skin covers were used in 113 hypospadiac urethroplasties. Results: The first surgery was curative in 74 (65% of 113 patients. In the remaining 39 (35%, various complications included 12 urethro-cutaneous fistulas (UCFs, 10 urethral strictures, six cases each of penile torsion and meatal stenosis and five cases each of superficial necrosis and poor cosmesis. Of these 39 patients, 25 (64% recovered with conservative treatment and 14 (36% required re-operation, i.e. UCFs and strictures in four cases each and penile torsion, meatal stenosis and dog-ears in two cases each. All the 12 UCFs were single

    ABSTRACT: INTRODUCTION: The occurrence of intussusception in adults is rare. The condition is found in 1 in 1300 abdominal operations and 1 in 100 patients operated for intestinal obstruction. The child to adult ratio is 20:1. CASE PRESENTATION: A 52-year-old Irish Caucasian woman was investigated for a 3-month history of intermittent episodes of colicky midgut pain and associated constipation. Ileocolonoscopy revealed a pedunculated lesion in the terminal ileum prolapsing into the caecum. Computed tomography confirmed a smooth-walled, nonobstructing, low density intramural lesion in the terminal ileum with secondary intussusception. A laparoscopic small bowel resection was performed. Histology revealed a large pedunculated polypoidal mass measuring 4 x 2.5 x 2 cm consistent with a submucosal lipoma. She had complete resolution of her symptoms and remained well at 12-month follow-up. CONCLUSION: This case highlights an unusual cause of incomplete small bowel obstruction successfully treated through interdisciplinary cooperation. Ileal lipomas are not typically amenable to endoscopic removal and require resection. This can be successfully achieved via a laparoscopic approach with early restoration of premorbid functioning.

    Since Frankel reported the congenital anomalous intestinal duplication incidentally during autopsy in 1883, about 228 cases has been reported on the literatures. In our severance hospital, one case of ileal duplication was found, and was confirmed by pathology and surgery. This patient of duplication usually reveals the symptoms of abnormal distension, pain and palpable abdominal mass, and sometimes the symptoms of intestinal obstruction. On x-ray flate abdomen, huge occupying mass displaces intestinal gas pattern to left side. Barium enema study reveals elongation and displacement of ileum by large extrinsic mass. And cecum is also displaced upward. On the IVP, this extrinsic mass is not related to kidneys. Also, the literature was reviewed.

    Today's options for biliary bypass procedures, for difficult choledocholithiasis, range from open surgery to laparo-endoscopic hybrid procedures. The aim of this study was to analyze the outcomes of patients with difficult choledocholithiasis treated with laparoscopic choledochoduodenostomy. We performed a prospective observational study from March 2011 to June 2016. We included patients with difficult common bile duct stones (recurrent or unresolved by ERCP) in which a biliary bypass procedure was required. We performed a laparoscopic bile duct exploration with choledochoduodenostomy and intraoperative cholangioscopy. A total of 19 patients were included. We found female predominance (78.9%), advanced mean age (72.4±12 years) and multiple comorbidities. Most patients with previous episodes of choledocholitiasis or cholangitis, mode 1 (min-max: 1-7). Mean common bile duct diameter 24.9±7mm. Mean operative time 218.5±74min, estimated blood loss 150 (30-600)mL, resume of oral intake 3.2±1 days, postoperative length of stay 4.9±2 days. We found a median of 18 (12-32) months of follow-up. All patients with normalization of liver enzymes during follow-up. One patient presented with sump syndrome and one patient died due to nosocomial pneumonia. Laparoscopic choledochoduodenostomy with intraoperative cholangioscopy seems to be safe and effective treatment for patients with difficult common bile duct stones no resolved by endoscopic procedures. This procedure is a good option for patients with advanced age and multiple comorbidities. We offer all the advantages of minimally invasive surgery to these patients. Copyright © 2017 AEC.

    Copper is normally supplemented in poultry diets as a growth promotant and antimicrobial. However, there are conflicting reports about the growth benefits and little information about how Cu affects the microbiota in the intestinal tract of poultry. Therefore, in vitro and in vivo experiments were conducted with broilers to determine the effects of Cu source and supplementation on ileal microbiota. The influence of Cu on growth of lactobacilli and Escherichia coli in media inoculated with ileal contents was determined in the first study. When Cu sulfate pentahydrate was supplemented to the cultures, quadratic increases in lactobacilli to graded concentrations of Cu up to 125 mg/kg and quadratic decreases in E. coli up to 250 mg/kg of Cu were observed after 24 h of incubation at 37 degrees C. However, when tribasic Cu chloride (TBCC) was supplemented, neither linear nor quadratic responses to graded concentrations of dietary Cu were observed on number of lactobacilli or number of E. coli. The effects of Cu and Cu source on ileal microbiota and growth performance in broiler chickens were determined in the second study. Bird performance was not affected by Cu source or concentration. The bacterial culture enumeration results revealed that supplementation with 187.5 mg/kg of Cu from Cu sulfate pentahydrate and TBCC had no effect on number of ileal lactobacilli of birds. The denaturing gradient gel electrophoresis analyses of ileal microbial communities revealed that neither Cu supplementation nor source had effects on the number of bacterial species predominant in the ileal digesta or associated with the ileal mucosa. Supplementation with TBCC supplementation significantly increased the similarity coefficients of microbiota in the ileal mucosa compared with cross-products of all individuals. This suggests that TBCC may alter the intestinal microbiota, yet this shift had no effect on bird performance.

The management of TMJ ankylosis has a complicated chore and it is challenging for the maxillofacial surgeon because of technical hitches and high rate of re-ankylosis. Interpositional gap arthroplasty is one of the modalities for its management. A range of inter-positional materials have been used to avert recurrence after gap arthroplasty in TMJ ankylosis. The aim of this series was to evaluate the effectiveness of the temporomyofacial flap in the treatment of TMJ ankylosis as an interpositional gap arthroplasty. A total of 10 cases with unilateral TMJ ankylosis were treated by interpositional gap arthroplasty by pedicled temporalis myofacial flap and evaluated with a follow-up of 6 months to 5 years (Mean 3.3 years) for the functional stability of TMJ. All the patients were successfully treated. There were no signs of recurrence in any patients up to last follow up visit. The result showed that temporalis myofascial flap is a preferable choice for inter-positional gap arthroplasty which proves its versatility as an inter-positional material.

    Patients undergoing laparoscopic splenectomy were observed for their postoperative recovery and development of complications. It was a retrospective analysis done at Services Hospital and National Hospital and Medical Center, Lahore, from January 2010 to December 2012. A total of 13 patients underwent laparoscopic splenectomy and were included in the study. Patients were followed for their postoperative recovery and development of any complications. The median age of patients was 19 years ranging from 13 to 69 years. Accessory spleens were removed in 3 patients. Mean operating time was 158 minutes. One operation had to be converted to open because of uncontrolled hemorrhage. Six patients experienced postoperative complications including unexplained hyperpyrexia (n=2), pleural effusion (n=4) and prolonged pain > 48 hours (n=1). No deaths or infections were seen. Seven out of 8 patients with idiopathic thrombocytopenic purpura developed a positive immediate response to the splenectomy, defined as a platelet count greater than 100 x 109/L after the surgery, which was maintained without medical therapy. Mean hospital stay was 5.5 days. Average time to return to activity was 15 days. All patients were followed for 6 months and no follow-up complications were noted. (author)

    To review the post-operative morbidity and mortality of total esophagogastrectomy (TEG) with second barrier lymphadenectomy (D2) with interposition of a transverse colon and to determine the oncological outcomes of TEG D2 with interposition of a transverse colon. This study consisted of a retrospective review of patients with a cancer diagnosis who underwent TEG between 1997 and 2013. Demographic data, surgery protocols, complications according to Clavien-Dindo classifications, final pathological reports, oncological follow-ups and causes of death were recorded. We used the TNM 2010 and Japanese classifications for nodal dissection of gastric cancer. We used descriptive statistical analysis and Kaplan-Meier survival curves. A P-value of less than 0.05 was considered statistically significant. The series consisted of 21 patients (80.9% men). The median age was 60 years. The 2 main surgical indications were extensive esophagogastric junction cancers (85.7%) and double cancers (14.2%). The mean total surgery time was 405 min (352-465 min). Interposition of a transverse colon through the posterior mediastinum was used for replacement in all cases. Splenectomy was required in 13 patients (61.9%), distal pancreatectomy was required in 2 patients (9.5%) and resection of the left adrenal gland was required in 1 patient (4.7%). No residual cancer surgery was achieved in 75.1% of patients. A total of 71.4% of patients had a postoperative complication. Respiratory complications were the most frequently observed complication. Postoperative mortality was 5.8%. Median follow-up was 13.4 mo. Surgery specific survival at 5 years of follow-up was 32.8%; for patients with curative surgery, it was 39.5% at 5 years. TEG for cancer with interposition of a transverse colon is a very complex surgery, and it presents high post-operative morbidity and adequate oncological outcomes.

    Despite current advances in microsurgery, fingertip replantation is still controversial, mainly due to its difficulty and cost. The purpose of this study is to describe a new technique of interposition vein graft guided by polypropylene suture in distal fingertip replantation. A total of eight consecutive Tamai zone 1 fingertip replantations performed by the same author were included. All replantations were performed using interposition vein graft guided by polypropylene suture. This technique involved a vein graft of ∼ 2 cm, with appropriate calibration, obtained from the volar part of the forearm and a 2-0 polyprolene suture passed through the interposition vein graft. Then, a polypropylene suture guide carrying the vein graft was inserted into the artery. The anastomosis was easily performed with the aid of 10-0 or 11-0 nylon in a bloodless medium and without encountering the posterior wall problem. Average surgery time was 2.5 hours (range = 2-3 hours). Among eight Tamai zone 1 replantations, six were successful (75%). There were two replantations lost because of arterial failure. This technique may ease fingertip replantations and increase the success rate for Tamai zone 1 injuries.

    Rotator cuff reconstructions may be improved by adding growth factors, cells, or other biologic factors into the repair zone. This usually requires a biological carrier (scaffold) to be integrated into the construct and placed in the area of tendon-to-bone healing. This needs to be done without affecting the constructs mechanics. Hypothesis/ The hypothesis was that scaffold placement, as an interposition, has no adverse effects on biomechanical properties of double-row rotator cuff repair. The purpose of this study was to examine the effect of scaffold interposition on the initial strength of rotator cuff repairs. Controlled laboratory study. Twenty-five fresh-frozen shoulders (mean age: 65.5 ± 8.9 years) were randomly assigned to 5 groups. Groups were chosen to represent a broad spectrum of commonly used scaffold types: (1) double-row repair without augmentation, (2) double-row repair with interposition of a fibrin clot (Viscogel), (3) double-row repair with interposition of a collagen scaffold (Mucograft) between tendon and bone, (4) double-row repair with interposition of human dermis patch (ArthroFlex) between tendon and bone, and (5) double-row repair with human dermis patch (ArthroFlex) placed on top of the repair. Cyclic loading to measure displacement was performed to 3000 cycles at 1 Hz with an applied 10- to 100-N load. The ultimate load to failure was determined at a rate of 31 mm/min. There were no significant differences in mean displacement under cyclic loading, slope, or energy absorbed to failure between all groups (P = .128, P = .981, P = .105). Ultimate load to failure of repairs that used the collagen patch as an interposition (573.3 ± 75.6 N) and a dermis patch on top of the reconstruction (575.8 ± 22.6 N) was higher compared with the repair without a scaffold (348.9 ± 98.8 N; P = .018 and P = .025). No significant differences were found for repairs with the fibrin clot as an interposition (426.9 ± 103.6 N) and the decellularized dermis

    Two experiments with growing pigs were conducted to determine the effects of dietary P and Ca levels, phytase supplementation, and ileal pectin infusion on changes in bacterial populations in the ileum and on ileal and fecal fermentation patterns. Growing pigs (BW 30.1 +/- 1.3 kg) were fitted with simple T-cannulas at the distal ileum and were fed a low-P corn-soybean meal control diet (3 g of P/kg), or the control diet supplemented with either 15 g of monocalcium phosphate (MCP)/kg (Exp. 1) or 1,000 phytase units of phytase/kg (Exp. 2). Daily infusion treatments consisted of either 60 g of pectin dissolved in 1.8 L of demineralized water or 1.8 L of demineralized water as a control infusion, infused via the ileal cannula. In each experiment, 8 barrows were assigned to 4 dietary treatments according to a double incomplete 4 x 2 Latin square design. The dietary treatments in Exp. 1 were the control diet with water infusion, the control diet with pectin infusion, the MCP diet with water infusion, or the MCP diet with pectin infusion. In Exp. 2, the pigs received the same control treatments as in Exp. 1 and the phytase diet in combination with water or pectin infusion. Gene copy numbers of total bacteria, Lactobacillus spp., Lactobacillus reuteri, Lactobacillus amylovorus/Lactobacillus sobrius, Lactobacillus mucosae, Enterococcus spp., Enterococcus faecium, Enterococcus faecalis, bifidobacteria, the Clostridium coccoides cluster, the Clostridium leptum cluster, the Bacteroides-Prevotella-Porphyrmonas group, and Enterobacteriaceae were determined by quantitative PCR in DNA extracts of ileal digesta. In Exp. 1, addition of MCP reduced ileal gene copy numbers of Enterococcus spp. (P = 0.048), E. faecium (P = 0.015), and the C. leptum cluster (P = 0.028), whereas pectin infusion enhanced (P = 0.008) ileal d-lactate concentration. In Exp. 2, supplemental phytase led to greater ileal gene copy numbers of the C. coccoides (P = 0.041) and C. leptum (P = 0.048) clusters and

    The purpose of our study was to evaluate the overall prevalence and clinical significance of interposition of the posterior cruciate ligament (PCL) into the medial compartment of the knee joint in coronal magnetic resonance imaging (MRI). We retrospectively reviewed 317 consecutive patients referred for knee MRI at our institution between October 2009 and December 2009. Interposition of the PCL into the medial compartment of the knee joint on proton coronal MRI was evaluated dichotomously (i.e., present or absent). We analyzed the interposition according to its prevalence as well as its relationship with right-left sidedness, gender, age, and disease categories (osteoarthritis, anterior cruciate ligament tear, and medial meniscus tear). Prevalence of interposition of PCL into the medial compartment of the knee joint was 47.0% (149/317). There was no right (50.0%, 83/166) to left (43.7%, 66/151) or male (50.3%, 87/173) to female (43.1%, 62/144) differences in the prevalence. There was no significant association between the prevalence and age, or the disease categories. Interposition of the PCL into the medial compartment of the knee joint is observed in almost half of patients on proton coronal MRI of the knee. Its presence is not associated with any particular factors including knee pathology and may be regarded as a normal MR finding.

    Robotic surgery offers advantages for operating in a narrow space such as inside the pelvis. We report on the technique of robotic-assisted laparoscopic total proctocolectomy with lymphadenectomy and ileal pouch-anal anastomosis for ulcerative colitis with transverse colitic cancer, using the single cart position. A 46-year-old female patient was diagnosed with colitic cancer of the transverse colon during the surveillance of ulcerative colitis. Six port sites were used. Mobilization of the left-sided colon through to the rectum and mobilization of the transverse colon with lymphadenectomy around the middle colic artery were performed using the robotic surgical system. After rectal mobilization was conducted near the anus, the right side of the colon was mobilized and the ileum resected laparoscopically. Thereafter, a mucosectomy of the proctorectum was carried out through a trans-anal approach, and a hand-sewn J-pouch was performed. Finally, a diverting ileostomy was constructed through the right lower abdomen. The operative time was 460 minutes, including the console time of 361 minutes. The amount of blood loss was 76 g. The patient was discharged on postoperative day nine. Pathological results demonstrated that the depth of the lesion was T3, and the positive lymph node was 1 of 115 retrieved lymph nodes. There were no complications or mortality. Robotic-assisted total proctocolectomy and lymphadenectomy with ileal pouch-anal anastomosis for transverse colitic cancer of ulcerative colitis was performed safely using the single cart position.

    A method for assessing the patency of the H-graft interposition mesocaval shunts by computerized tomography is described. Five patients with such shunts were examined with a 5.5 second CT scanner. After locating the graft a 50 cc bolus of 76% diatrizoate was injected into a cubital vein and 3-4 scans were executed at a preselected level. A distinct vessel like enhancement appeared if the shunt was open. With dynamic CT-scanning the flow can be demonstrated in graphical form as time-density curves.

    Full Text Available Objective To compare the erectile function (EF and sexual desire (SD in men after radical cystoprostatectomy (RCP who had either an ileal conduit urinary diversion or orthotropic ileal neobladder substitution. Materials and Methods Eighty one sexually active men with bladder cancer were enrolled in this prospective study. After RCP according to patients' preferences they underwent either ileal conduit urinary diversion (n = 41 or orthotropic ileal neobladder substitution (n = 40. EF and SD were assessed using International Index of Erectile Function (IIEF questionnaire. Patients were assessed at 4-week before surgery and were followed up at 1, 6, and 12-month postoperatively using the same questionnaire. Results Postoperatively the EF and SD domains deteriorated significantly in both groups, but in a small proportion of the patients submitted to ileal neobladder they gradually improved with time (P = 0.006. At 12-month postoperative period, 4 (9.8% and 14 (35.0% patients in ileal conduit and ileal neobladder groups were able to achieve erections hard enough for vaginal penetration and maintained their erection to completion of intercourse, respectively (P = 0.006. Among patients in the ileal conduit and ileal neobladder groups, additional 4 (9.8% and 7 (17.1% patients were able to get some erection, but were unable to maintain their erection to completion of intercourse (P = 0.02. At 12-month follow up period 24.4% of the ileal conduit and 45.0% of the ileal neobladder patients rated their sexual desire very high or high (P = 0.01. Conclusion When performed properly, orthotopic ileal neobladder substitution after RCP offers better long-term results in terms of EF and SD.

    Full Text Available Pouch prolapse is a complication following the creation of restorative proctocolectomy. There is a paucity of information in the literature pertaining to its management. An ileal J pouch patient with dyschezia presented to our Pouch Center. Under sedation, pouchos- copy was performed with a gastroscope. We detected an anterior distal pouch mucosal prolapse, 1.5 cm in diameter, blocking the anal canal. The prolapsed mucosa was excised with hot snare under a retroflex view. There was no bleeding or perforation. The entire procedure took 25 minutes. The patient tolerated the procedure well and was discharged home 30 minutes after post-procedural observation. The patient reported the resolution of the dyschezia symptom. The histopathological examination of excised specimen showed small bowel mucosa and sub-mucosa with changes compatible with mucosal prolapse. En- doscopic hot snare appears to be feasible in the management of pouch mucosal prolapse. Resumo: O prolapso da bolsa ileal é uma complicação que pode surgir após a criação da proctoco- lectomia restauradora. As informações na literatura são escassas quanto ao tratamento. Um paciente com bolsa ileal em “J” e apresentando disquezia deu entrada em nosso centro médico. Sob sedação, realizamos uma endoscopia da bolsa ileal. Detectamos uma bolsa distal anterior com prolapso da mucosa, com 1,5 cm de diâmetro, bloqueando o canal anal. O prolapso da mucosa foi retirado com alça diatérmica sob visão retroflexa. Não houve san- gramento ou perfuração. A duração de todo o processo foi de 25 minutos. O paciente tolerou bem o procedimento e recebeu alta após 30 minutos de observação pós-procedimento. O paciente relatou a resolução do sintoma de disquezia. O exame histopatológico do espéci- me extirpado mostrou a mucosa e submucosa do intestino delgado com alterações com- patíveis com o prolapso da mucosa.

    Congenital brachymetatarsia, a shortened metatarsal bone, can be corrected surgically by callus distraction or one-stage lengthening using bone graft. We asked whether one-stage metatarsal lengthening using metatarsal homologous bone graft could improve forefoot function, lead to metatarsal healing, restore metatarsal parabola, and improve cosmetic appearance. We retrospectively reviewed 29 patients (41 feet) in whom we lengthened 50 metatarsals. Surgery consisted of a transverse proximal osteotomy of the metatarsal shaft and interposition of a metatarsal homologous bone graft (average, 13 mm long) fixed with an intramedullary Kirschner wire. Minimum followup was 3 years (mean, 5 years; range, 3-11 years). Bone union was achieved in all cases. The mean preoperative American Orthopaedic Foot and Ankle Society score was 37 points (range, 28-53 points) and the mean postoperative score was 88 points (range, 74-96 points), with an average improvement of 51 points. Radiographically, the mean gain in length was 13 mm (range, 10-15 mm), and the mean percentage increase was 23%. One-stage metatarsal lengthening using interposition of metatarsal homologous bone graft to correct congenital brachymetatarsia has low morbidity for the patient, limited complications, short recovery times, and restores forefoot anatomy.

    Talocalcaneal joint middle facet coalition is the most common tarsal coalition, occurring in ≤2% of the population. Fewer than 50% of involved feet obtain lasting relief of symptoms after nonoperative treatment, and surgical intervention is commonly used to relieve symptoms, increase the range of motion, improve function, reconstruct concomitant pes planovalgus, and prevent future arthrosis from occurring at the surrounding joints. Several approaches to surgical intervention are available for patients with middle facet coalitions, ranging from resection to hindfoot arthrodesis. We present a series of 4 cases, in 3 adolescent patients, of talocalcaneal joint middle facet coalition resection with interposition of a particulate juvenile hyaline cartilaginous allograft (DeNovo(®) NT Natural Tissue Graft, Zimmer, Inc., Warsaw, IN). With a mean follow-up period of 42.8 ± 2.9 (range 41 to 47) months, the 3 adolescent patients in the present series were doing well with improved subtalar joint motion and decreased pain, and 1 foot showed no bony regrowth on a follow-up computed tomography scan. The use of a particulate juvenile hyaline cartilaginous allograft as interposition material after talocalcaneal middle facet coalition resection combined with adjunct procedures to address concomitant pes planovalgus resulted in good short-term outcomes in 4 feet in 3 adolescent patients.

    Since early 1990’s, when it was inaugurally introduced, laparoscopic splenectomy has been performed with excellent results in terms of intraoperative and postoperative complications. Nowadays laparoscopic splenectomy is the approach of choice for both benign and malignant diseases of the spleen. However some contraindications still apply. The evolution of the technology has allowed though, cases which were considered to be absolute contraindications for performing a minimal invasive procedure to be treated with modified laparoscopic approaches. Moreover, the introduction of advanced laparoscopic tools for ligation resulted in less intraoperative complications. Today, laparoscopic splenectomy is considered safe, with better outcomes in comparison to open splenectomy, and the increased experience of surgeons allows operative times comparable to those of an open splenectomy. In this review we discuss the indications and the contraindications of laparoscopic splenectomy. Moreover we analyze the standard and modified surgical approaches, and we evaluate the short-term and long-term outcomes. PMID:28979707

    Full Text Available Laparoscopic surgery provides patients with less painful surgery but is more demanding for the surgeon. The increased technological complexity and sometimes poorly adapted equipment have led to increased complaints of surgeon fatigue and discomfort during laparoscopic surgery. Ergonomic integration and suitable laparoscopic operating room environment are essential to improve efficiency, safety, and comfort for the operating team. Understanding ergonomics can not only make life of surgeon comfortable in the operating room but also reduce physical strains on surgeon.

    A 55-year-old man with hepatitis B virus antigen-positive liver cirrhosis was admitted to our hospital with anal bleeding. Colonoscopy revealed blood retention in the entire colon, but no bleeding lesion was found. Computed tomography images showed that vessels in the ileum were connected to the right testicular vein, and we suspected ileal varices to be the most probable cause of bleeding. We immediately performed double balloon enteroscopy, but failed to find any site of bleeding owing to the difficulty of fiberscope insertion with sever adhesion. Using a balloon catheter during retrograde transvenous venography, we found ileal varices communicating with the right testicular vein (efferent vein) with the superior mesenteric vein branch as the afferent vein of these varices. We performed balloon occluded retrograde transvenous obliteration by way of the efferent vein of the varices and have detected no further bleeding in this patient one year after treatment.

    2017-10-01

    Full Text Available Background. Every effort should be made to optimize surgical techniques and to minimize potential morbidity rates associated with live donor operations. Advances in a minimally invasive approach by robotic surgery to donor nephrectomy have raised the possibility of applying this technique to live donor bowel resections for intestinal transplantation. Methods. We report the first 5 consecutive cases of a robotic-assisted live donor ileal segmentectomy. We describe the technical aspects of the procedure, discuss the rationale for considering this option, and evaluate potential advantages of this approach. Results. We found that this new approach is associated with less postoperative discomfort, a shorter hospital length of stay, and a faster recovery of bowel function compared to our previous open surgery. Conclusions. Our initial experience suggests that robotic surgery is a safe and feasible procedure for live donor ileal resection for intestinal transplantation and is a useful alternative to conventional open surgery.

    A case of moving ileal Taenia saginata parasites is presented with demonstrative images. We came across the parasites surprisingly while performing robot-assisted laparoscopic radical cystoprostatectomy with intracorporeal Studer pouch urinary diversion. We recommend stool sample evaluation in the preoperative period for possible presence of intestinal parasitic diseases, particularly in patients with bladder cancer who are admitted from areas with an increased incidence of intestinal parasitic diseases, before opening the bowel segments during surgery to perform radical cystectomy and urinary diversion.

    Abstract Rationale: Laparoscopic total pancreatectomy is a complicated surgical procedure and rarely been reported. This study was conducted to investigate the safety and feasibility of laparoscopic total pancreatectomy. Patients and Methods: Three patients underwent laparoscopic total pancreatectomy between May 2014 and August 2015. We reviewed their general demographic data, perioperative details, and short-term outcomes. General morbidity was assessed using Clavien–Dindo classification and delayed gastric emptying (DGE) was evaluated by International Study Group of Pancreatic Surgery (ISGPS) definition. Diagnosis and Outcomes: The indications for laparoscopic total pancreatectomy were intraductal papillary mucinous neoplasm (IPMN) (n = 2) and pancreatic neuroendocrine tumor (PNET) (n = 1). All patients underwent laparoscopic pylorus and spleen-preserving total pancreatectomy, the mean operative time was 490 minutes (range 450–540 minutes), the mean estimated blood loss was 266 mL (range 100–400 minutes); 2 patients suffered from postoperative complication. All the patients recovered uneventfully with conservative treatment and discharged with a mean hospital stay 18 days (range 8–24 days). The short-term (from 108 to 600 days) follow up demonstrated 3 patients had normal and consistent glycated hemoglobin (HbA1c) level with acceptable quality of life. Lessons: Laparoscopic total pancreatectomy is feasible and safe in selected patients and pylorus and spleen preserving technique should be considered. Further prospective randomized studies are needed to obtain a comprehensive understanding the role of laparoscopic technique in total pancreatectomy. PMID:28099344

    The complication of growth disturbance after physeal fracture of the distal tibia has been well recognized. Although irreducible fractures of the physis due to trapped soft tissue, including periosteum, are not common, it could still cause growth disturbances. Therefore, the detection of periosteal interposition with physeal injury on imaging study is important. We present a case of a 10-year-old girl with surgically confirmed periosteal interposition in the distal tibial Salter-Harris type I fracture, through magnetic resonance imaging findings.

    Ileal pouch anal anastomosis (IPAA) may alter sexuality and fertility in women. The laparoscopic approach seems to reduce infertility rates in women after IPAA. However, the impact of hand sewn versus stapled IPAA on sexuality and fertility has never been assessed in patients with ulcerative colitis (UC). The objective of this study was to analyze the impact of the IPAA technique on sexuality and fertility in UC. All UC patients who underwent an IPAA between May 1996 and April 2011 were included. The patients answered mailed questionnaires including sexuality validated questionnaires and fertility questionnaires. The risk factors of sexual dysfunction were explored. A total of 135 patients were included. Eighty-eight patients (65%) answered the questionnaires. Their mean age and follow-up were 37.2 ± 13.4 y and 109.7 ± 57.5 mo. The rates of female and male sexual dysfunction were 50% and 29%, respectively. Intestinal transit disorders were identified as risk factors in both men and women and anastomotic stricture in women sexual dysfunction, in univariate analyses. The IPAA technique did not impact sexual function in women but there was a trend for less erectile dysfunction after hand sewn IPAA (16.7% versus 44.4%). The fertility rate was 47% in women and 75% in men, with a trend for a better fertility in women after hand sewn IPAA (P = 0.07). In this preliminary study, the hand sewn or stapled IPAA technique did not impact the sexuality or fertility outcomes of UC patients, but there was a trend for better female fertility and male erectile function after hand sewn IPAA. Intestinal transit disorders contributed to male and female sexual dysfunction after IPAA. Copyright © 2016 Elsevier Inc. All rights reserved.

    Pelvic fracture urethral defects associated with urethrorectal fistulas are rare and difficult to repair. The aim of this study was to evaluate the efficacy of transperineal urethroplasty with gracilis muscle interposition for the repair of pelvic fracture urethral defects associated with urethrorectal fistulas. We identified 32 patients who underwent transperineal urethroplasty with gracilis muscle interposition to repair pelvic fracture urethral defects associated with urethrorectal fistulas. Patient demographics as well as preoperative, operative and postoperative data were obtained. Mean followup was 33 months (range 6 to 64). The overall success rate was 91% (29 of 32 cases). One-stage repair was successful in 17 of 18 patients (94%) using perineal anastomosis with separation of the corporeal body and in 12 of 14 (86%) using perineal anastomosis with inferior pubectomy and separation of the corporeal body. All 22 patients (100%) without a previous history of repair were successfully treated. However, only 7 of 10 patients (70%) with a previous history of failed urethroplasty and urethrorectal fistula repair were cured. Recurrent urethral strictures developed in 2 cases. One patient was treated successfully with optical internal urethrotomy and the other was treated successfully with tubed perineoscrotal flap urethroplasty. Recurrent urethrorectal fistulas associated with urethral strictures developed in an additional patient. Transperineal urethroplasty with gracilis muscle interposition is a safe and effective surgical procedure for most pelvic fracture urethral defects associated with urethrorectal fistulas. Several other factors may affect its postoperative efficiency. Copyright © 2017 American Urological Association Education and Research, Inc. Published by Elsevier Inc. All rights reserved.

    The purpose of the review was to evaluate the feasibility and outcome of laparoscopic pancreatic cystogastrostomy for operative drainage of symptomatic pancreatic pseudocysts. A retrospective review of all patients who underwent laparoscopic pancreatic cystogastrostomy between June 1997 and July 2001 was performed. Data regarding etiology of pancreatitis, size of pseudocyst, operative time, complications, and pseudocyst recurrence were collected and reported as median values with ranges. Laparoscopic pancreatic cystogastrostomy was attempted in 6 patients. Pseudocyst etiology included gallstone pancreatitis (3), alcohol-induced pancreatitis (2), and post-ERCP pancreatitis (1). The cystogastrostomy was successfully performed laparoscopically in 5 of 6 patients. However, the procedure was converted to open after creation of the cystgastrostomy in 1 of these patients. There were no complications in the cases completed laparoscopically and no deaths in the entire group. No pseudocyst recurrences were observed with a median followup of 44 months (range 4-59 months). Laparoscopic pancreatic cystgastrostomy is a feasible surgical treatment of pancreatic pseudocysts with a resultant low pseudocyst recurrence rate, length of stay, and low morbidity and mortality.

    Filshie, G M

    1989-09-01

    An overview of laparoscopic sterilization techniques from a historical and practical viewpoint includes instrumentation, operative techniques, mechanical occlusive devices, anesthesia, failure rates, morbidity and mortality. Laparoscope was first reported in 1893, but was developed simultaneously in France, Great Britain, Canada and the US in the 1960s. There are smaller laparoscopes for double-puncture procedures, and larger, single-puncture laparoscopes. To use a ring or clip, a much larger operating channel, up to 8 mm is needed. Insufflating gas may be CO2, which does not support combustion, but is more uncomfortable, NO2, which is also an anesthetic, and room air often used in developing countries. Unipolar electrocautery is now rarely used, in fact most third party payers do not allow it. Bipolar cautery, thermal coagulation and laser photocoagulation are safer methods. Falope rings, Hulka-Clemens, Filshie, Bleier, Weck and Tupla clips are described and illustrated. General anesthesia, usually a short acting agent with a muscle relaxant, causes 33% of the mortality of laparoscope, often due to cardiac arrest and arrhythmias, preventable with atropine. Local anesthesia is safer and cheaper and often used in developing countries. Failure rates of the various laparoscopic tubal sterilization methods are reviewed: most result from fistula formation. Mortality and morbidity can be caused by bowel damage, injury or infection, pre- existing pelvic infection, hemorrhage, gas embolism (avoidable by the saline drip test), and other rare events.

    Innovative techniques have a really magical attraction for physicians as well as for patients. The number of robotic-assisted procedures worldwide has almost tripled from 80,000 procedures in the year 2007 to 205,000 procedures in 2010. In the same time the total number of Da Vinci surgery systems sold climbed from 800 to 1,400. Advantages, such as three-dimensional visualization, a tremor-filter, an excellent instrument handling with 6 degrees of freedom and better ergonomics, together with aggressive marketing led to a veritable flood of new Da Vinci acquisitions in the whole world. Many just took the opportunity to introduce a new instrument to save a long learning curve and start immediately in the surgical master class.If Da Vinci sacrocolpopexy is compared with the conventional laparoscopic approach, robotic-assisted sacrocolpopexy shows a significantly longer duration of the procedure, a higher need for postoperative analgesics, much higher costs and an identical functional outcome without any advantage over the conventional laparoscopic approach. Although the use of robotic-assisted systems shows a significantly lower learning curve for laparoscopic beginners, it only shows minimal advantages for the experienced laparoscopic surgeon. Therefore it remains uncertain whether robotic-assisted surgery shows a significant advantage compared to the conventional laparoscopic surgery, especially with small reconstructive laparoscopic procedures such as sacrocolpopexy.

    2000-01-01

    Full Text Available This work is aimed at identifying factors associated with primary jejunum-ileal tumors malignancy, defining a prediction model with sensitivity, specificity and accuracy to distinguish malign from benign neoplasms. These tumors are rare, have highly unspecific presentation and, frequently, are diagnosed late. We reviewed the charts of 42 patients with primary jejunum-ileal tumors treated in the Department of General Surgery of Rio de Janeiro State University Hospital, Rio de Janeiro, RJ, Brazil, from 1969 to 1998. We performed bivariate analyses, based on chi² test, searching associations between tumors malignancy and demographic and clinical variables. Then logistic regression was employed to consider the independent effect of variables previously identified on malignancy risk. The malign tumors included 11 adenocarcinomas, 7 leiomyosarcomas, 5 carcinoids and 4 lymphomas; the benign tumors included 10 leiomyomas, 2 hamartomas, and single cases of adenoma, multiple neurilemoma and choristoma. The bivariate analyses indicated the association between malignancy and palpable abdominal mass (P = 0.003, period from signs and symptoms onset to diagnosis (P = 0.016, anemia (P = 0.020, anorexia (P = 0.003, abdominal pain (P = 0.031, weight loss (P = 0.001, nausea and vomit (P = 0.094, and intestinal obstruction (P = 0.066; no association with patients demographic characteristics were found. In the final logistic regression model, weight loss, anemia and intestinal obstruction were statistically associated with the dependent variable of interest. Based only on three variables -- weight loss, anemia and intestinal obstruction -- the model defined was able to predict primary jejunum-ileal tumors malignancy with sensitivity of 85.2%, specificity of 80.0%, and accuracy of 83.3%.

    A 12-year-old girl presented with prolonged fever with no obvious focus on either history or clinical examination. High-resolution computerized tomography of the chest revealed the ‘tree-in-bud’ sign in the right lung and necrotic mediastinal lymph nodes. Barium meal showed multiple ileal strictures. The child was treated with anti-tuberculous therapy for six months. At follow-up six months later, the child had gained weight and had no signs of intestinal obstruction. Tuberculosis is a common cause of fever of undetermined origin and should be investigated for especially in countries with a high prevalence. PMID:25478420

    Full Text Available Duplications of the alimentary tract are rare congenital anomalies which can be found at all levels of the alimentary tract. Majority of the duplications present as spherical cysts and usually range from a few millimeters to less than ten centimeters in size. Duplications produce complications such as intestinal obstruction or hemorrhage. A two-month-old infant presented with recurrent episodes of bleeding per rectum. Laparotomy revealed a giant ileal duplicated bowel segment which exhibited extensive gastric heterotopia with focal ulceration.

    Duplication cysts of the gastrointestinal tract are rare congenital abnormalities. Ectopic gastric mucosa, which can be found in duplications, may cause peptic ulceration, gastrointestinal bleeding or perforation. We report a 1-year-old boy with a perforated ileal duplication cyst with haemorrhagic pseudocyst formation caused by peptic ulceration of the duplication cyst. It presented a snowman-like appearance consisting of a small, thick-walled, true enteric cyst and a large, thin-walled haemorrhagic pseudocyst on US and CT. It is an unusual manifestation of a duplication cyst, which has not been reported in the English language literature. (orig.)

    Variceal bleeding is an unusual complication of ileal conduits. We report a case in which recurrent stomal variceal hemorrhage from an ileal conduit for bladder cancer was successfully treated by percutaneous transhepatic obliteration (PTO) using microcoils and N-butyl cyanoacrylate. Therefore, PTO can be one treatment option to prevent recurrent stomal variceal bleeding from ileal conduits.

    The current nature of tendon-bone healing after rotator cuff (RC) repair is still the formation of granulation tissue at the tendon-bone interface rather than the formation of fibrocartilage, which is the crucial structure in native tendon insertion and can be observed after knee ligament reconstruction. The interposition of calcium phosphate materials has been found to be able to enhance tendon-bone healing in knee ligament reconstruction. However, whether the interposition of these kinds of materials can enhance tendon-bone healing or even change the current nature of tendon-bone healing after RC repair still needs to be explored. The interposition of calcium phosphate materials during RC repair would enhance tendon-bone healing or change its current nature of granulation tissue formation into a more favorable process. Controlled laboratory study. A total of 144 male Sprague-Dawley rats underwent unilateral detachment of the supraspinatus tendon, followed by delayed repair after 3 weeks. The animals were allocated into 1 of 3 groups: (1) repair alone, (2) repair with Ca5(PO4)2SiO4 (CPS) bioceramic interposition, or (3) repair with hydroxyapatite (HA) bioceramic interposition at the tendon-bone interface. Animals were sacrificed at 2, 4, or 8 weeks postoperatively, and microcomputed tomography (micro-CT) was used to quantify the new bone formation at the repair site. New fibrocartilage formation and collagen organization at the tendon-bone interface was evaluated by histomorphometric analysis. Biomechanical testing of the supraspinatus tendon-bone complex was performed. Statistical analysis was performed using 1-way analysis of variance. Significance was set at P repair, CPS bioceramic significantly increased the area of fibrocartilage at the tendon-bone interface compared with the control and HA groups. Moreover, CPS and HA bioceramics had significantly improved collagen organization. Biomechanical tests indicated that the CPS and HA groups have greater ultimate

    This study was performed to evaluate the effectiveness of overlapping the temporalis fascia flaps (TFFs) and the sternocleidomastoid muscle flaps (SCMFs) as physical barriers to treat established Frey syndrome and concavity after parotidectomy. We retrospectively reviewed 17 patients who underwent corrective procedures with simultaneous TFF and SCMF interposition for the treatment of Frey syndrome. The affected areas of the cheek skin were identified with starch-iodine tests. The facial contours of the patients were classified as bilaterally symmetric (BS), with a slightly shallow (SS) contour on the surgical side, or with a conspicuously shallow (CS) contour on the surgical side. The sample was followed up for a mean of 22 months. The average area of gustatory-sweating positive skin was reduced from 12.80 to 1.32 square centimeters postoperatively. The facial asymmetry secondary to parotidectomy was greatly improved. The authors concluded that this technique was efficacious in ameliorating Frey syndrome and facial concavity secondary to parotidectomy. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available Parastomal hernia, defined as an “incisional hernia related to an abdominal wall stoma”, is a frequent complication after conduit urinary diversion that can negatively impact quality of life and present a clinically significant problem for many patients. Parastomal hernia (PH rates may be as high as 65% and while many patients are asymptomatic, in some series up to 30% of patients require surgical intervention due to pain, leakage, ostomy appliance problems, urinary obstruction, and rarely bowel obstruction or strangulation. Local tissue repair, stoma relocation, and mesh repairs have been performed to correct PH, however, long-term results have been disappointing with recurrence rates of 30%–76% reported after these techniques. Due to high recurrence rates and the potential morbidity of PH repair, efforts have been made to prevent PH development at the time of the initial surgery. Randomized trials of circumstomal prophylactic mesh placement at the time of colostomy and ileostomy stoma formation have shown significant reductions in PH rates with acceptably low complication profiles. We have placed prophylactic mesh at the time of ileal conduit creation in patients at high risk for PH development and found it to be safe and effective in reducing the PH rates over the short-term. In this review, we describe the clinical and radiographic definitions of PH, the clinical impact and risk factors associated with its development, and the use of prophylactic mesh placement for patients undergoing ileal conduit urinary diversion with the intent of reducing PH rates.

    Massive irreparable rotator cuff tears are a difficult problem. Modalities such as irrigation and debridement, partial repair, tendon transfer and grafts have been utilized with high failure rates and mixed results. Synthetic interpositional patch repairs are a novel and increasingly used approach. The present study aimed to examine the biomechanical properties of common synthetic materials for interpositional repairs in contrast to native tendon. Six ovine tendons, six polytetrafluoroethylene (PTFE) felt sections and six expanded PTFE (ePTFE) patch sections were pulled-to-failure to analyze their biomechanical and material properties. Six direct tendon-to-bone surgical method repairs, six interpositional PTFE felt patch repairs and six interpositional ePTFE patch repairs were also constructed in ovine shoulders and pulled-to-failure to examine the biomechanical properties of each repair construct. Ovine tendon had higher load-to-failure (591 N) and had greater stiffness (108 N/mm) than either PTFE felt (296 N, 28 N/mm) or ePTFE patch sections (323 N, 34 N/mm). Both PTFE felt and ePTFE repair techniques required greater load-to-failure (225 N and 177 N, respectively) than direct tendon-to-bone surgical repairs (147 N) in ovine models. Synthetic materials lacked several biomechanical properties, including strength and stiffness, compared to ovine tendon. Interpositional surgical repair models with these materials were significantly stronger than direct tendon-to-bone model repairs.

    2014-09-01

    Metastases from ileal neuroendocrine tumors (NETs) to the myocardium are rare and generally seen in patients with widespread metastatic NET disease. The objectives of this investigation were to describe the frequency of intracardiac metastases in ileal NET patients examined by (68)Ga-DOTA-TOC-PET/CT and to describe the cases in detail. All (68)Ga-DOTA-TOC-PET/CT examinations performed at the Karolinska University Hospital since 2010 until April 2012 were reviewed. In all, 128 out of 337 examinations were in patients with ileal NETs. Four patients had seven myocardiac metastases, yielding a frequency of 4.3 % in patients with ileal NETs. One patient had cardiac surgery while three were treated with somatostatin analogs. The cardiac metastases did not affect the patients' activity of daily life. (68)Ga-DOTA-TOC-PET/CT is an established imaging modality in identifying cardiac metastases in ileal NETs. Prospective studies are needed to confirm the true clinical value of (68)Ga-DOTA-TOC-PET/CT in detecting cardiac metastases in both ileal and non-ileal NETs.

    Laparoscopic adenomectomy is a feasible and effective surgical procedure. We have progressively simplified the procedure using barbed sutures and a technique we call "knotless" laparoscopic adenomectomy. We present a prospective, multicenter, descriptive study that reflects the efficacy and safety of this technique in an actual, reproducible clinical practice situation. A total of 26 patients with benign prostatic hyperplasia of considerable size (>80cc) underwent "knotless" laparoscopic adenomectomy. This is an extraperitoneal laparoscopic technique with 4 trocars based on the controlled and hemostatic enucleation of the adenoma using ultrasonic scalpels, precise urethral sectioning under direct vision assisted by a urethral plug, trigonization using barbed suture covering the posterior wall of the fascia, capsulorrhaphy with barbed suture and extraction of the morcellated adenoma through the umbilical incision. The median patient age was 69 (54-83)years, the mean prostate volume was 127 (89-245)cc, the mean operative time was 136 (90-315)min, the mean estimated bleeding volume was 200 (120-500)cc and the hospital stay was 3 (2-6)days. All patients experienced improved function in terms of uroflowmetry and International Prostate Symptom Score and quality of life questionnaires. There were complications in 6 patients, 5 of which were minor. "Knotless" laparoscopic adenomectomy is a procedure with low complexity that combines the advantages of open surgery (lasting functional results and complete extraction of the adenoma) with laparoscopic procedures (reduced bleeding and need for transfusions, shorter hospital stays and reduced morbidity and complications related to the abdominal wall). The use of ultrasonic scalpels and barbed sutures simplifies the procedure and enables a safe and hemostatic technique. Copyright © 2014 AEU. Publicado por Elsevier España, S.L.U.

    2015-08-01

    Full Text Available ABSTRACTBackground:Uretero-ileal anastomotic stricture (UIAS is a urological complication after ileal neobladder, the initial management being endourological intervention. If this fails or stricture recurs, surgical intervention will be indicated.Design and Participants:From 1994 to 2013, 129 patients were treated for UIAS after unsuccessful endourological intervention. Unilateral UIAS was present in 101 patients, and bilateral in 28 patients; total procedures were 157. The previous ileal neobladder techniques were Hautmann neobladder, detubularized U shape, or spherical shape neobladder.Surgical procedures:Dipping technique was performed in 74 UIAS. Detour technique was done in 60 renal units. Ileal Bladder flap was indicated in 23 renal units. Each procedure ended with insertion of double J, abdominal drain, and indwelling catheter.Results:Follow-up was done for 12 to 36 months. Patency of the anastomosis was found in 91.7 % of cases. Thirteen patients (8.3% underwent antegrade dilatation and insertion of double J.Conclusion:After endourological treatment for uretero-ileal anastomotic failure, basically three techniques may be indicated: dipping technique, detour technique, and ileal bladder flap. The indications are dependent on the length of the stenotic/dilated ureteral segment. Better results for long length of stenotic ureter are obtained with detour technique; for short length stenotic ureter dipping technique; when the stenotic segment is 5 cm or more with a short ureter, the ileal tube flap is indicated. The use of double J stent is mandatory in the majority of cases. Early intervention is the rule for protecting renal units from progressive loss of function.

    Full Text Available Gossypiboma is defined as a mass caused by foreign body reaction developed around the retained surgical item in the operative area. When diagnosed, it should be removed in symptomatic patients. Minimal invasive surgery should be planned for the removal of the retained item. The number of cases treated by laparoscopic approach is rare in the literature. We present a case of forty-year-old woman referred to emergency room with acute abdomen diagnosed as gossypiboma and treated successfully with laparoscopic surgery.

    2015-01-01

    We report a case of a prolapsed patent vitellointestinal duct (PVID) in a 2-month-old girl child who presented with sudden increase in size of a polypoidal lesion into a large, ‘Y’-shaped reddish, prolapsing lesion, discharging gaseous and faecal matter at her umbilicus. The lesion was diagnosed as a prolapse of inverted ileal loops through the PVID. The child had no associated congenital anomalies. A transumbilical exploration was performed, followed by wedge resection and anastomosis. The child tolerated the procedure well and the postoperative course was uneventful. If the omphalomesenteric duct fails to obliterate a range of congenital defects related to the umbilicus, it can become clinically apparent. Meckel's diverticulum is the commonest of these defects but is most often asymptomatic. PVID is the most common symptomatic anomaly of the patent omphalomesenteric duct and requires prompt surgical correction to avoid complications. PMID:26494719

    Full Text Available A rare case of neonatal Bartter syndrome presenting with severe hyperkalemia is reported in a preterm child born to consanguineous parents. This child also had ileal atresia, and meconium plugs were found at laparotomy. The diagnosis of cystic fibrosis was subsequently made on genetic testing. Despite full intensive care management and surgical interventions, he died of respiratory failure after 70 days. This is the first reported case of such conglomeration of pathologies in a newborn child. Second, in highlighting this case we want clinicians to be aware that a subtype of neonatal Bartter syndrome can present with initial hyperkalemia so that an erroneous diagnosis of pseudohypoaldosteronism is not made when this is seen in combination with hyperkalemia and hyperrenin hyperaldosteronism.

    Full Text Available Bladder outlet obstruction due to benign prostatic hyperplasia (BPH remains one of the most common problems of men in the advanced age group. Open prostatectomy for patients with large BPH is still the standard treatment recommended by the European Association of Urology and is performed quiet often. Disadvantages of this method of treatment are significant surgical trauma and high rate of perioperative complications . Laparoscopic modification of simple prostatectomy presents a worthy minimal invasive alternative to open surgical treatment of BPH. From November 2014 to December 2015, laparoscopic adenomectomy was performed for 16 patients. 7 (43.5% patients had transperitoneal (TP and 9 (56.25% patients had extraperitoneal (EP laparoscopic simple prostatectomy. None of the cases required conversion . All patients were discharged in satisfactory condition with complete restoration of free micturation. Laparoscopic prostatectomy as a method of surgical treatment for BPH can be easily reproducible. It can be adopted as a routine urological practice for large-sized BPH with the aim of minimizing operative trauma and achieving short hospital stay.

    Amino acid compositions of ovine muscle, ovine myofibrillar protein, ovine spleen, ovine liver, bovine blood plasma, bovine blood globulins and bovine serum albumin and the amino acid compositions and in vivo (laboratory rat) true ileal amino acid digestibilities of hydrolysates (sequential hydrolysis with Neutrase, Alcalase and Flavourzyme) of these protein sources were determined. True ileal amino acid digestibility differed (Pprotein hydrolysates. The ovine myofibrillar protein and liver hydrolysates were the most digestible, with a mean true ileal digestibility across all amino acids of 99%. The least digestible protein hydrolysate was bovine serum albumin with a comparable mean true ileal digestibility of 93%. When the digestible amino acid contents were expressed as proportions relative to lysine, considerable differences, across the diverse protein sources, were found in the pattern of predicted absorbed amino acids.

    2012-08-01

    The true ileal digestibility assay provides the most informative measure of digestibility to assess bioavailability of amino acids in foods for humans. To determine 'true' estimates of ileal amino acid digestibility, requires that endogenous amino acids present in digesta at the terminal ileum be quantified. The amounts of endogenous amino acids in ileal digesta can be determined after feeding an animal or human a protein-free diet (traditional approach) or by various methods after giving a protein-containing diet. When the protein-free method has been applied with adult human subjects an overall mean value (three separate studies) for endogenous ileal nitrogen flow of 800 mg N/d has been reported. This value is considerably lower than a comparable value obtained after feeding protein of 1852 mg N/d (mean of four separate studies), and thus endogenous ileal N and amino acids should be measured under conditions of protein alimentation. There is some confusion concerning the terminology used to define digestibility, with the term "true" digestibility having different adopted meanings. Here, true amino acid digestibility is defined as apparent amino acid digestibility corrected for the basal amino acid losses determined after giving either a protein-free or a protein-containing diet. Basal losses should be determined at a defined dry-matter and protein intake. The protein-free diet approach to determining endogenous amino acids is considered unphysiological and basal losses refer to ileal endogenous amino acid flows associated with digesta dry-matter flow, and not including "specific" effects of dietary factors such as non starch polysaccharides and anti nutritional factors. Arguments are advanced that the enzyme hydrolysed protein/ultra filtration method may be suitable for routine application with a cannulated pig model, to obtain physiologically-valid basal estimates of ileal endogenous amino acids to allow calculation of true ileal amino acid digestibility in the

    Although the many advantages of laparoscopic surgery have made it an established technique, training in laparoscopic surgery posed problems not encountered in conventional surgical training. Virtual reality simulators open up new perspectives for training in laparoscopic surgery. Under realistic conditions in real time, trainees can tailor their sessions with the VR simulator to suit their needs and goals, and can repeat exercises as often as they wish. VR simulators reduce the number of experimental animals needed for training purposes and are suited to the pursuit of research in laparoscopic surgery.

  7. Single access laparoscopic nephrectomy

    Directory of Open Access Journals (Sweden)

    Jay D Raman

    2008-01-01

    Full Text Available Laparoscopic nephrectomy has assumed a central role in the management of benign and malignant kidney diseases. While laparoscopy is less morbid than open surgery, it still requires several incisions each at least 1-2 cm in length. Each incision carries morbidity risks of bleeding, hernia and/or internal organ damage, and incrementally decreases cosmesis. An alternative to conventional laparoscopy is single access or keyhole surgery, which utilizes magnetic anchoring and guidance system (MAGS technology or articulating laparoscopic instruments. These technical innovations obviate the need to externally space trocars for triangulation, thus allowing for the creation of a small, solitary portal of entry into the abdomen. Laboratory and early clinical series demonstrate feasibility as well as safe and successful completion of keyhole nephrectomy. Future work is necessary to improve existing instrumentation, increase clinical experience, assess benefits of this surgical approach, and explore other potential applications for this technique.

    AIM: To study the transcolonic extraction of the proximally resected colonic specimens by colonoscopic assistance at laparoscopic colonic surgery. METHODS: The diagnoses of our patients were Crohn’s disease, carcinoid of appendix and adenocarcinoma of cecum. We preferred laparoscopic total mesocolic resections. Colon and terminal ileum were divided with endoscopic staplers. A colonoscope was placed per anal and moved proximally in the colon till to reach the colonic closed end under the laparoscopic guidance. The stump of the colon was opened with laparoscopic scissors. A snare of colonoscope was released and the intraperitoneal complete free colonic specimen was grasped. Specimen was moved in to the colon with the help of the laparoscopic graspers and pulled gently through the large bowel and extracted through the anus. The open end of the colon was closed again and the ileal limb and the colon were anastomosed intracorporeally with a 60-mm laparoscopic stapler. The common enterotomy orifice was closed in two layers with a running intracorporeal suture. RESULTS: There were three patients with laparoscopic right-sided colonic resections and their specimens were intended to remove through the remnant colon by colonoscopy but the procedure failed in one patient (adenocarcinoma) due to a bulky mass and the specimen extraction was converted to transvaginal route. All the patients had prior abdominal surgeries and had related adhesions. The operating times were 210, 300 and 500 min. The lengths of the specimens were 13, 17 and 27 cm. In our cases, there were no superficial or deep surgical site infections or any other complications. The patients were discharged uneventfully within 4-5 d and they were asymptomatic after a mean 7.6 mo follow-up (ranged 4-12). As far as we know, there were only 12 cases reported yet on transcolonic extraction of the proximal colonic specimens by colonoscopic assistance after laparoscopic resections. With our cases, success rate of the

    Specimen retrieval bags have long been used in laparoscopic gynecologic surgery for contained removal of adnexal cysts and masses. More recently, the concerns regarding spread of malignant cells during mechanical morcellation of myoma have led to an additional use of specimen retrieval bags for contained "in-bag" morcellation. This review will discuss the indications for use retrieval bags in gynecologic endoscopy, and describe the different specimen bags available to date.

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

    Radiofrequency has been used as a tool for liver resection since 2002. A new laparoscopic device is reported in this article that assists liver resection laparoscopically. From October 2006 to the present, patients suitable for liver resection were assessed carefully for laparoscopic resection with the laparoscopic Habib Sealer (LHS). Detailed data of patients resected laparoscopically with this device were collected prospectively and analyzed. In all, 28 patients underwent attempted laparoscopic liver resection. Four cases had to be converted to an open approach because of extensive adhesions from previous colonic operations. Twenty-four patients completed the procedure comprising tumorectomy (n = 7), multiple tumoretcomies (n = 5), segmentectomy (n = 3), and bisegmentectomies (n = 9). Vascular clamping of portal triads was not used. The mean resection time was 60 +/- 23 min (mean +/- SD), and blood loss was 48 +/- 54 mL. None of the patients received any transfusion of blood or blood products perioperatively or postoperatively. Postoperatively, 1 patient developed severe exacerbation of asthma that required steroid therapy, and 1 other patient had a transient episode of liver failure that required supportive care. The mean duration of hospital stay was 5.6 +/- 2 days (mean +/- SD). At a short-term follow up, no recurrence was detected in patients with liver cancer. Laparoscopic liver resection can be performed safely with this new laparoscopic liver resection device with a significantly low risk of intraoperative bleeding or postoperative complications.

    Full Text Available Of the various options for patients with end stage renal disease, kidney transplantation is the treatment of choice for a suitable patient. The kidney for transplantation is retrieved from either a cadaver or a live donor. Living donor nephrectomy has been developed as a method to address the shortfall in cadaveric kidneys available for transplantation. Laparoscopic living donor nephrectomy (LLDN, by reducing postoperative pain, shortening convalescence, and improving the cosmetic outcome of the donor nephrectomy, has shown the potential to increase the number of living kidney donations further by removing some of the disincentives inherent to donation itself. The technique of LLDN has undergone evolution at different transplant centers and many modifications have been done to improve donor safety and recipient outcome. Virtually all donors eligible for an open surgical procedure may also undergo the laparoscopic operation. Various earlier contraindications to LDN, such as right donor kidney, multiple vessels, anomalous vasculature and obesity have been overcome with increasing experience. Laparoscopic live donor nephrectomy can be done transperitoneally or retroperitoneally on either side. The approach is most commonly transperitoneal, which allows adequate working space and easy dissection. A review of literature and our experience with regards to standard approach and the modifications is presented including a cost saving model for the developing countries. An assessment has been made, of the impact of LDN on the outcome of donor and the recipient.

    The standard treatment for patients with early-stage cervical cancer has been radical hysterectomy. However, for women interested in future fertility, radical trachelectomy is now considered a safe and feasible option. The use of minimally invasive surgical techniques to perform this procedure has recently been reported. We report the first case of a laparoscopic radical trachelectomy performed in a developing country. The patient is a nulligravid, 30-y-old female with stage IB1 adenocarcinoma of the cervix who desired future fertility. She underwent a laparoscopic radical trachelectomy and bilateral pelvic lymph node dissection. The operative time was 340 min, and the estimated blood loss was 100mL. There were no intraoperative or postoperative complications. The final pathology showed no evidence of residual disease, and all pelvic lymph nodes were negative. At 20 mo of follow-up, the patient is having regular menses but has not yet attempted to become pregnant. There is no evidence of recurrence. Laparoscopic radical trachelectomy with pelvic lymphadenectomy in a young woman who desires future fertility may also be an alternative technique in the treatment of early cervical cancer in developing countries.

    The purpose of this study was to assess the diagnostic value of epidural fat interposition between the dura mater and spinous process of L5 as an indirect sign of spondylolysis on mid-sagittal MR imaging of the lumbar spine. Mid-sagittal T1-weighted MR images of the lumbar spine of 85 patients with spondylolysis and 93 patients without pars interarticularis fractures were randomized and evaluated by a masked reader. After a training sample of five cases, the reader was asked to note the presence or absence of epidural fat interposition between the dura mater and spinous process of L5 on the randomized images. The epidural fat interposition between the dura mater and spinous process of L5 was noted in 67 out of the 85 patients with spondylolysis (78.8%) and three of the patients without pars interarticularis fracture (3.2%). The difference was statistically significant (P<0.01). This sign has a specificity of 96.7%, sensitivity of 78.8%, positive predictive value of 95.7%, negative predictive value of 83.3% and accuracy of 88.2% for diagnosis of spondylolysis. Epidural fat interposition between the dura mater and spinous process may be a helpful sign for the diagnosis of spondylolysis on mid-sagittal MR imaging of the lumbar spine. (orig.)

    We report our experience of concomitant laparoscopic treatment for enterocele and stapled transanal rectal resection (STARR) for rectocele and/or rectal prolapse in patients with complex obstructed defecation syndrome (ODS). From June 2005 to June 2007, we submitted 20 patients with ODS due to rectal prolapse and/or rectocele, combined with stable enterocele, to STARR and laparoscopic correction of the enterocele. Preoperative assessment included symptom evaluation with standardized questionnaires, clinical examination, colonoscopy, proctoscopy, anal sphincter ultrasonography, video-defecography with synchronous opacification of the ileal loops in all patients and colpography in female patients, and anorectal manometry. Follow-up was performed in the first, third, sixth, 12th, and 24th month after surgery. Eighteen (90%) patients were submitted to both procedures, simultaneously. One patient, previously submitted to STARR, underwent laparoscopic treatment of the enterocele. Postoperative complications occurred in two (10%) patients: one case of postoperative rectal bleeding and one case of retropneumoperitoneum. Median (range) preoperative and postoperative Altomare's obstructed defecation score was ten (6-14) and two (0-14), respectively (p<0.001). Median (range) preoperative and postoperative quality of life score was 79 (39-109) and 109 (50-126), respectively (p<0.001). No symptom related to ODS was detected at 6-month follow-up (19 patients) and at 24-month follow-up (19 patients). The combination of STARR and laparoscopy provides a safe and effective method to treat ODS caused by rectal internal prolapse and/or rectocele combined with enterocele.

  18. Laparoscopic pelvic sling placement facilitates optimum therapeutic radiotherapy delivery in the management of pelvic malignancy.

    Joyce, M

    2012-02-01

    BACKGROUND: Radiotherapy has a significant role in the management of pelvic malignancies. However, the small intestine represents the main dose limiting organ. Invasive and non-invasive mechanical methods have been described to displace bowel out of the radiation field. We herein report a case series of laparoscopic placement of an absorbable pelvic sling in patients requiring pelvic radiotherapy. METHODS: Six patients were referred to our minimally invasive unit. Four patients required radical radiotherapy for localised prostate cancer, one was scheduled for salvage localised radiotherapy for post-prostatectomy PSA progression and one patient required adjuvant radiotherapy post-cystoprostatectomy for bladder carcinoma. All patients had excessive small intestine within the radiation fields despite the use of non-invasive displacement methods. RESULTS: All patients underwent laparoscopic mesh placement, allowing for an elevation of small bowel from the pelvis. The presence of an ileal conduit or previous surgery did not prevent mesh placement. Post-operative planning radiotherapy CT scans confirmed displacement of the small intestine allowing all patients to receive safely the planned radiotherapy in terms of both volume and radiation schedule. CONCLUSION: Laparoscopic mesh placement represents a safe and efficient procedure in patients requiring high-dose pelvic radiation, presenting with unacceptable small intestine volume in the radiation field. This procedure is also feasible in those that have undergone previous major abdominal surgery.

    Full Text Available While the 'best pancreatic anastomosis technique' debate is going during Whipple procedure, the laparoscopic pancreaticoduodenectomy lately began to appear more and more often in the medical literature. All the popular anastomosis techniques used in open pancreas surgery are being experienced in laparoscopic pancreaticoduodenectomy. However, when they were adapted to laparoscopy, their implementation was not technically easy, and assistance of robotic surgery was sometimes required at the pancreatic anastomosis stage of the procedure. Feasibility and simplicity of a new technique have a vital role in its adaptation to laparoscopic surgery. We frequently use the extra-mucosal single row handsewn anastomosis method in open and laparoscopic surgery of the stomach, small and large bowel and we found it easy and reliable. Here, we defined the adaptation of this technique to the laparoscopic pancreas anastomosis. The outcomes were not inferior to the other previously described techniques and it has the advantage of simplicity.

    Primary cheek teratomas are rare with joint ankylosis (TMJA). The fundamental aim in the treatment of TMJA is the successful surgical resection of ankylotic bone, prevention of recurrence, and aesthetic improvement by ensuring functional occlusion. Early treatment is necessary to promote proper growth and function of mandible and to facilitate the positive psychological development of child. Inter-positional arthroplasty with ultra-thin silicone sheet was performed. Advantages include short operative time, less foreign material in the joint space leading to negligible foreign body reactions and least chances of implant extrusion. Instead of excising a large bony segment, a thin silicone sheet was interposed and then sutured ensuring preservation of mandibular height. Aggressive post-operative physiotherapy with custom made dynamic jaw exerciser was used to prevent recurrence.

    Full Text Available Background: Periodontal therapy has developed beyond the scope of the treatment of periodontal pathoses. Periodontal plastic surgery consists of the reconstructive procedures designed to enhance the both function and esthetics. Deficient ridges pose a severe problem to the restorative dentist in restoring the natural form, function and esthetics of the prosthesis replacing the natural dentition. Depending upon the severity, location of these defects and the prosthetic option chosen, hard and soft tissue ridge augmentation or non-surgical approach or a combination may help to address them. The present clinical report describes a soft tissue ridge augmentation of a localized ridge defect in maxillary aesthetic region using onlay interpositional graft followed by fixed partial denture.

    Heterotopic ossification around the elbow can lead to considerable functional disability. We describe a case of a 42-year-old man who developed heterotopic ossification of his elbow after closed reduction of the elbow dislocation and radial neck fracture and retrograde intramedullary nailing for radial neck fracture. During the follow-up after initial surgery, movements of the elbow were gradually deteriorated and diagnosed as heterotopic ossification of the elbow. Implant removal, radial head excision along with heterotopic mass, and also interposition of the anconeus muscle resulted in improvement of his elbow mobility. At 18 months of follow-up, patient had elbow flexion arc of 15°-110°, 70° of supination, and 50° of pronation without recurrence of heterotopic ossification. The uniqueness of this case lies in the treatment of heterotopic ossification of the elbow to prevent its recurrence, which was developed after retrograde intramedullary nailing for radial neck fracture following closed reduction.

    An experiment was conducted to estimate true ileal phosphorus (P:) digestibility of 3 meat and bone meal samples (MBM-1, MBM-2: , and MBM-3:) for broiler chickens. Four semipurified diets were formulated from each sample to contain graded concentrations of P. The experiment was conducted as a completely randomized design with 6 replicates (6 birds per replicate) per dietary treatment. A total of 432 Ross 308 broilers were assigned at 21 d of age to the 12 test diets. The apparent ileal digestibility coefficient of P was determined by the indicator method, and the linear regression method was used to determine the true P digestibility coefficient. The apparent ileal digestibility coefficient of P in birds fed diets containing MBM-1 and MBM-2 was unaffected by increasing dietary concentrations of P (P > 0.05). The apparent ileal digestibility coefficient of P in birds fed the MBM-3 diets decreased with increasing P concentrations (linear, P digestibility of MBM-1, MBM-2, and MBM-3 was determined to be 0.693, 0.608, and 0.420, respectively. True ileal P digestibility coefficients determined for MBM-1 and MBM-2 were similar (P digestible P contents of MBM-1, MBM-2, and MBM-3 were determined to be 37.5 and 26.0; 60.2 and 36.6; and 59.8 and 25.1 g/kg, respectively, on an as-fed basis. © 2015 Poultry Science Association Inc.

    Chronic pancreatitis is a painful inflammatory disease that leads to progressive and irreversible destruction of pancreatic parenchyma [1]. A lateral pancreaticojejunostomy, also known as the Puestow procedure, is performed for symptomatic chronic pancreatitis associated with a dilated pancreatic duct secondary to calcifications or strictures [4]. An open approach is used traditionally due to the complexity of the case, and there have only been a handful of laparoscopic case reports [2]. This video depicts a laparoscopic lateral pancreaticojejunostomy for chronic pancreatitis. A 45-year-old gentleman with a 20-year history of chronic alcohol abuse presented with diffuse abdominal pain. His pain was worse postprandially and associated with loose stools. A computed tomography scan revealed multiple calcified deposits within the body and tail of the pancreas, and a dilated pancreatic duct measuring 1.4 cm with a proximal obstructing calcified stone. A 5-port foregut technique was used, and a 15-cm pancreatic ductotomy was performed with an ultrasonic scalpel. Calcified stones were cleared from the duct, and a roux-en-y pancreaticojejunostomy was performed using a hand-sewn technique. The patient had a relatively uncomplicated hospital course with return of bowel function on postoperative day 4. His patient-controlled analgesic device was discontinued on post operative day 3. He was ambulating, tolerating a regular diet and discharged home on postoperative day 5. At 12- and 26-month follow-up, he remains off narcotics, but still requires 1-2 tabs of pancreatic enzyme replacement per meal. Most importantly, he has not had any alcohol for over 2 years. The two primary goals in treating chronic pancreatitis include long-term pain relief and improvements in quality of life [3]. For patients with chronic pancreatitis and a dilated pancreatic duct, a laparoscopic lateral pancreaticojejunostomy may be an effective approach to decrease pain and improve quality of life.

    Intraluminal small bowel hematoma has been rarely reported in children, as a rare cause of small bowel obstruction. We present a case of an intraluminal ileal hematoma presenting as small bowel obstruction in a child. Computed Tomography (CT) indicated a large intraluminal hyperdense lesion in the distal ileum as the cause of small bowel obstruction. Abdominal ultrasonography (US) showed an echogenic mass-like lesion with multiple septa in the distal ileum. Small bowel obstruction due to a complicated cystic mass was provisionally diagnosed. Histopathologic examination of the resected mass suggested a submucosal ileal hematoma. Although intraluminal small bowel hematoma is rare in children, it can present as an intraluminal cystic mass and should be considered as a rare cause of small bowel obstruction. The US and CT findings of submucosal ileal hematoma could be useful for the diagnosis of such cases in the future

    A 48-year-old woman with alcoholic liver cirrhosis was admitted to our hospital because of hematochezia and severe anemia. She had been hospitalized many times over the past year for hematochezia of unknown etiology. Contrast-enhanced CT demonstrated ileal varices, which were fed by several ileal veins. These feeding veins were selectively embolized with N-butyl cyanoacrylate (NBCA) via a recanalized paraumbilical vein. The paraumbilical vein instead of the portal vein was punctured to decrease the risk of bleeding complications because she had coagulopathy and ascites. We consider antegrade embolization of ileal varices with NBCA to be a feasible and effective treatment. Access via a paraumbilical vein is an alternative to the transhepatic approach.Level of Evidence Level V, case report.

    Full Text Available A rare case of ileal perforation, as a fatal initial presentation of total colonic aganglionosis (TCA in infancy is reported. A 10-week-old boy, was brought to the emergency department with symptoms of complicated intestinal obstruction. He looked ill, was lethargic, markedly dehydrated and had a severely distended abdomen. An abdominal X-ray revealed multiple air fluid levels seen in a distended small intestine. During exploratory laparotomy the ileum was massively dilated with distal segment perforation. Ileal perforation repair was performed. A totally collapsed microcolon was identified. Biopsies were taken from the high rectum, sigmoid and hepatic flexure. Appendectomy and ileostomy were performed. All biopsies, as well as the appendix, showed absence of ganglion cells. Despite this procedure the patient progressively deteriorated and later died due to sepsis. Ileal perforation in infants is a rare, but potentially fatal initial presentation of TCA. Early detection is essential to prevent life-threatening complications.

    The role of laparoscopic surgery in treatment of patients with diverticulitis is unclear. A retrospective comparison of laparoscopic with conventional surgery for patients with chronic diverticulitis was performed to assess morbidity, recovery from surgery, and cost. Records of patients undergoing elective resection for uncomplicated diverticulitis from 1992 to 1994 at a single institution were reviewed. Laparoscopic resection involved complete intracorporeal dissection, bowel division, and anastomosis with extracorporeal placement of an anvil. Sigmoid and left colon resections were performed laparoscopically in 25 patients and by open technique in 17 patients by two independent operating teams. No significant differences existed in age, gender, weight, comorbidities, or operations performed. In the laparoscopic group, three operations were converted to open laparotomy (12 percent) because of unclear anatomy. Major complications occurred in two patients who underwent laparoscopic resection, both requiring laparotomy, and in one patient in the conventional surgery group who underwent computed tomographic-guided drainage of an abscess. Patients who underwent laparoscopic resection tolerated a regular diet sooner than patients who underwent conventional surgery (3.2 +/- 0.9 vs. 5.7 +/- 1.1 days; P < 0.001) and were discharged from the hospital earlier (4.2 +/- 1.1 vs. 6.8 +/- 1.1 days; P < 0.001). Overall costs were higher in the laparoscopic group than the open surgery group ($10,230 +/- 49.1 vs. $7,068 +/- 37.1; P < 0.001) because of a significantly longer total operating room time (397 +/- 9.1 vs. 115 +/- 5.1 min; P < 0.001). Follow-up studies with a mean of one year revealed two port site infections in the laparoscopic group and one wound infection in the open group. Of patients undergoing conventional resection, one patient experienced a postoperative bowel obstruction that was managed nonoperatively, and, in one patient, an incarcerated incisional hernia

    The totally laparoscopic approach to partial gastrectomy had not been compared previously with results of the open technique. This study compares the results of a series of laparoscopic cases with matched open cases. A retrospective case-matched study was performed in 36 patients (18 laparoscopic surgeries, 18 open surgeries). Each laparoscopic case was matched for patient age and indication for surgery. The intraoperative and postoperative details of the two groups were compared. Laparoscopic surgery resulted in less blood loss, although operative time was increased. Nasogastric tubes were less likely to be used after laparoscopic surgery, and patients in the laparoscopic group had an earlier return to normal bowel function than those in the open group. Length of hospital stay was 2 days shorter in the laparoscopic group. The totally laparoscopic approach to partial gastrectomy is an excellent alternative to the more traditional open approach. It results in a more rapid return of intestinal function and a shorter hospital stay.

  17. GATA4 Is Sufficient to Establish Jejunal Versus Ileal Identity in the Small IntestineSummary

    Full Text Available Background & Aims: Patterning of the small intestinal epithelium along its cephalocaudal axis establishes three functionally distinct regions: duodenum, jejunum, and ileum. Efficient nutrient assimilation and growth depend on the proper spatial patterning of specialized digestive and absorptive functions performed by duodenal, jejunal, and ileal enterocytes. When enterocyte function is disrupted by disease or injury, intestinal failure can occur. One approach to alleviate intestinal failure would be to restore lost enterocyte functions. The molecular mechanisms determining regionally defined enterocyte functions, however, are poorly delineated. We previously showed that GATA binding protein 4 (GATA4 is essential to define jejunal enterocytes. The goal of this study was to test the hypothesis that GATA4 is sufficient to confer jejunal identity within the intestinal epithelium. Methods: To test this hypothesis, we generated a novel Gata4 conditional knock-in mouse line and expressed GATA4 in the ileum, where it is absent. Results: We found that GATA4-expressing ileum lost ileal identity. The global gene expression profile of GATA4-expressing ileal epithelium aligned more closely with jejunum and duodenum rather than ileum. Focusing on jejunal vs ileal identity, we defined sets of jejunal and ileal genes likely to be regulated directly by GATA4 to suppress ileal identity and promote jejunal identity. Furthermore, our study implicates GATA4 as a transcriptional repressor of fibroblast growth factor 15 (Fgf15, which encodes an enterokine that has been implicated in an increasing number of human diseases. Conclusions: Overall, this study refines our understanding of an important GATA4-dependent molecular mechanism to pattern the intestinal epithelium along its cephalocaudal axis by elaborating on GATA4’s function as a crucial dominant molecular determinant of jejunal enterocyte identity.

    The purpose of this study was to develop and validate a method of directly measuring ileal bile acid absorption efficiency during a single enterohepatic cycle (first-pass ileal clearance). This has become feasible for the first time because of the availability of the synthetic gamma-labeled bile acid 75Selena-homocholic acid-taurine (75SeHCAT). Together with the corresponding natural bile acid cholic acid-taurine (labeled with 14C), SeHCAT was infused distal to an occluding balloon situated beyond the ampulla of Vater in six healthy subjects. Completion of a single enterohepatic cycle was assessed by obtaining a plateau for 75SeHCAT activity proximal to the occluding balloon, which prevented further cycles. Unabsorbed 75SeHCAT was collected after total gut washout, which was administered distal to the occluding balloon. 75SeHCAT activity in the rectal effluent measured by gamma counter was compared with that of absorbed 75SeHCAT level measured by gamma camera and was used to calculate first-pass ileal clearance. This was very efficient (mean value, 96%) and showed very little variation in the six subjects studied (range, 95%-97%). A parallel time-activity course in hepatic bile for 14C and 75Se during a single enterohepatic cycle, together with a ratio of unity for 14C/75Se in samples obtained at different time intervals, suggests that 75SeHCAT is handled by the ileum like the natural bile acid cholic acid-taurine. Extrapolation of 75SeHCAT first-pass ileal clearance to that of the natural bile acid therefore seems justifiable. In a subsidiary experiment, ileal absorption efficiency per day for 75SeHCAT was also measured by scanning the gallbladder area on 5 successive days after the measurement of first-pass ileal clearance. In contrast with absorption efficiency per cycle, absorption efficiency per day varied widely (49%-86%)

    The introduction of laparoscopic cholecystectomy has led to controversial discussions about the proceeding in case of coincident common bile duct stones. In our unit choledocholithiasis has been treated laparoscopically since November 1991. Basic requirement has been a routine intraoperative cholangiography. 67 patients with common bile duct stones were treated until January 1995. All patients underwent a follow up and the results were compared to other concepts. In 40 cases common bile duct stones were eliminated via cystic duct and in 27 cases by choledochotomy. The choledochus was drained routinely for postoperative x-ray control. In 9 cases we found residual concrements: 7 patients required postoperative endoscopic papillotomy and in 2 cases the calculi where eliminated with a dormia basket introduced via drainage tube. In one case surgical management was changed to laparotomy. Postoperative complications occurred in 8 cases. One patient suffering from bacterial peritonitis underwent laparotomy on the 9th postoperative day; one with bleeding from the cystic artery was treated by relaparoscopy. One patient developed a liver abscess and two patients a bilioma requiring ultrasound guided drainage. A superficial wound infection in one patient and a biliary leakage after removal of the drainage in two patients healed spontaneously. Due to an intact papilla with less stress to the patient, as well as a complication rate comparable with other published therapeutic concepts, this strategy can be recommended as a valuable alternative procedure.

    Full Text Available Abstract Background The purpose of this clinical study is to evaluate the feasibility of using 2-mm laparoscopic instruments to perform an appendectomy in patients with clinically suspected acute appendicitis and compare the outcome of this mini-laparoscopic or "needlescopic" approach to the conventional laparoscopic appendectomy. Methods Two groups of patients undergoing appendectomy over 24 months were studied. In the first group, needlescopic appendectomy was performed in 15 patients by surgeons specializing in advanced laparoscopy. These patients were compared with the second or control group that included 21 consecutive patients who underwent laparoscopic appendectomy. We compared the patients' demographic data, operative findings, complications, postoperative pain medicine requirements, length of hospital stay, and recovery variables. Differences were considered statistically significant at a p-value Results Patient demographics, history of previous abdominal surgery, and operative findings were similar in both groups. There was no conversion to open appendectomy in either group. No postoperative morbidity or mortality occurred in either group. The needlescopic group had a significantly shorter mean operative time (p = 0.02, reduced postoperative narcotics requirements (p = 0.05, shorter hospital stay (p = 0.04, and quicker return to work (p = 0.03 when compared with the laparoscopic group. Conclusions We conclude that the needlescopic technique is a safe and effective approach to appendectomy. When performed by experienced laparoscopic surgeons, the needlescopic technique results in significantly shorter postoperative convalescence and a prompt recovery.

    Laparoscopic surgery has become the treatment of choice for the management of perforated peptic ulcer. The advantages of laparoscopic repair for perforated peptic ulcer include less pain, a short hospital stay, and an early return to normal activity. Although the operation time of laparoscopic surgery is significantly longer than that of open surgery, laparoscopic technique is safe, feasible, and with morbidity and mortality comparable to that of the conventional open technique. To benefit from the advantages offered by minimally invasive laparoscopic technique, further study will need to determine whether laparoscopic surgery is safe in patients with generalized peritonitis or sepsis.

    The use of laparoscopy has been established in improving perioperative and postoperative outcomes for patients with simple appendicitis. Laparoscopic appendectomy is associated with less wound pain, less wound infection, a shorter hospital stay, and faster overall recovery when compared to the open appendectomy for uncomplicated cases. In the past two decades, the use of laparoscopy for the treatment of perforated appendicitis to take the advantages of minimally invasiveness has increased. This article reviewed the prevalence, approaches, safety disclaimers, perioperative and postoperative outcomes of the laparoscopic appendectomy in the treatment of patients with perforated appendicitis. Special issues including the conversion, interval appendectomy, laparoscopic approach for elderly or obese patient are also discussed to define the role of laparoscopic treatment for patients with perforated appendicitis.

    This study reviews our experience with laparoscopic cholecystectomy in the treatment of cholelithiasis in transplant patients. Demographic data, medications used, and operative and postoperative data of all transplant recipients who were subjected to laparoscopic cholecystectomy for cholelithiasis at our hospital were obtained. A total of 15 transplant patients (13 renal transplantation and 2 bone marrow transplantation) underwent laparoscopic cholecystectomy. All patients were admitted to the hospital on the day of the operation. The immunosuppressive regimen was not modified during hospitalization. Clinical presentation of cholelithiasis was biliary colicky (n=12), acute cholecystitis (n=2), and jaundice (n=1). The operation was uneventful in all patients. Postoperative complications were nausea and vomiting in 2 patients, prolonged tracheal intubation in 1, wound infection in 1 and large superficial hematoma in 1 patient. Laparoscopic cholecystectomy is associated to a low morbidity and mortality and good postoperative outcome in transplant patients with uncomplicated cholecystitis.

    For patients with recurrent inguinal hernia, or bilateral inguinal hernia, or for women, laparoscopic repair offers significant advantages over open techniques with regard to recurrence risk, pain, and recovery. For unilateral first-time hernias, either laparoscopic or open repair with mesh can offer excellent results. The major drawback of laparoscopy is that the technique requires a significant number of cases to master. For surgeons in group practice, it makes sense to have one surgeon in ...

    2015-11-01

    Full Text Available The authors report their experience in laparoscopic repair of inguinal hernias in children. From May 2010 to November 2013, 122 patients with inguinal hernia underwent laparoscopic herniorrhaphy (92 males and 30 females. Telescope used was 5 mm, while trocars for the operative instruments were 3 or 2 mm. After introducing the camera at the umbilical level and trocars in triangulation, a 4-0 nonabsorbable monofilament suture was inserted directly through the abdominal wall. The internal inguinal ring was then closed by N or double N suture. All operations were performed in one-day surgery setting. In the case of association of inguinal and umbilical hernia an original technique was performed for positioning and fixing the umbilical trocar and for the primary closure of the abdominal wall defect. The postoperative follow-up consisted of outpatient visits at 1 week and 1, 3, and 6 months. The mean age of patients was 38.5 months. Of all patients, 26 were also suffering from umbilical hernia (19 males and 7 females. A total of 160 herniorrhaphies were performed; 84 were unilateral (66 inguinal hernia, 18 inguinal hernia associated with umbilical hernia, 38 bilateral (30 inguinal hernia, 8 inguinal hernia associated with umbilical hernia. Nine of 122 patients (6 males and 3 females were operated in emergency for incarcerated hernia. A pre-operative diagnosis of unilateral inguinal hernia was performed in 106 cases. Of these patients, laparoscopy revealed a controlateral open internal inguinal ring in 22 cases (20.7%. The mean operative time was 29.9±15.9 min for the monolateral herniorrhaphies, while in case of bilateral repair the mean operative time was 41.5±10.4 min. The mean operative time for the repair of unilateral inguinal hernia associated with umbilical hernia was 30.1±7.4 while for the correction of bilateral inguinal hernia associated with umbilical hernia 39.5±10.6 min. There were 3 recurrences (1.8%: 2 cases in unilateral repair and

    Laparoscopic resection of hilar cholangiocarcinoma is technically challenging because it involves complicated laparoscopic procedures that include laparoscopic hepatoduodenal lymphadenectomy, hemihepatectomy with caudate lobectomy, and hepaticojejunostomy. There are currently very few reports describing this type of surgery. Between August 2014 and December 2014, 5 patients underwent total laparoscopic or laparoscopic-assisted surgery for hilar cholangiocarcinoma. Two patients with type I or II hilar cholangiocarcinoma underwent radical hilar resection. Three patients with type IIIa or IIIb cholangiocarcinoma underwent extended hemihepatectomy together with caudate lobectomy. The median (range) age, operation time, blood loss, and length of hospital stay were 63 years (43-76 years), 610 minutes (410-665 minutes), 650 mL (450-1,300 mL), and 12 days (9-21 days), respectively. Four patients had a negative margin, but 1 patient was diagnosed with high-grade dysplasia on the proximal resection margin. The median tumor size was 3.0 cm. One patient experienced postoperative biliary leakage, which resolved spontaneously. Laparoscopic resection is a feasible surgical approach in selected patients with hilar cholangiocarcinoma.

    2012-02-01

    BACKGROUND: Laparoscopic adrenalectomy is an attractive alternative to the traditional open approach in the surgical excision of an adrenal gland. It has replaced open adrenalectomy in our institution and we review our experience to date. METHODS: All cases of laparoscopic adrenalectomies in our hospital over eight years (from 2001 to May 2009) were retrospectively reviewed. Patient demographics, diagnosis, length of hospital stay, histology and all operative and post-operative details were evaluated. RESULTS: Fifty-five laparoscopic adrenalectomies (LA) were performed on 51 patients over eight years. The mean age was 48 years (Range 16-86 years) with the male: female ratio 1:2. Twenty-three cases had a right adrenalectomy, 24 had a left adrenalectomy and the remaining four patients had bilateral adrenalectomies. 91% were successfully completed laparoscopically with five converted to an open approach. Adenomas (functional and non functional) were the leading indication for LA, followed by phaeochromocytomas. Other indications for LA included Cushing\\'s disease, adrenal malignancies and rarer pathologies. There was one mortality from necrotising pancreatitis following a left adrenalectomy for severe Cushing\\'s disease, with subsequent death 10 days later. CONCLUSION: Laparoscopic adrenalectomy is effective for the treatment of adrenal tumours, fulfilling the criteria for the ideal minimally invasive procedure. It has replaced the traditional open approach in our centre and is a safe and effective alternative. However, in the case of severe Cushing\\'s disease, laparoscopic adrenalectomy has the potential for significant adverse outcomes and mortality.

The Endometriosis Care Centre of Australia and the private practices of authors. Two hundred and fifteen patients with clinical evidence of endometriosis examined laparoscopically between March 1999 and May 2001. Confirmation of endometriosis by histological biopsy. Endometriosis was confirmed in 168 of the 215 women. Of these women 38 had a previous negative laparoscopy within 12 months of the current laparoscopy. It is possible that in some of the patients, who previously had a negative laparoscopy, endometriosis was not recognised. Possible reasons for difficulty in diagnosis have been identified and techniques to improve diagnosis suggested. This retrospective study was performed to consider and explain the possibility of difficulties in diagnosis of endometriosis at previous laparoscopy.

The proportion of rapid eye movement (REM) sleep was not significantly changed after operation. There were no changes in arterial oxygen saturation on the postoperative...... compared with the preoperative night. Comparison of our results with previous studies on SWS and REM sleep disturbances after open laparotomy, suggests that the magnitude of surgery or administration of opioids, or both, may be important factors in the development of postoperative sleep disturbances.......The sleep pattern and oxygenation of 10 patients undergoing laparoscopic cholecystectomy were studied on the night before operation and the first night after operation.

    Full Text Available A comparative evaluation of three different techniques of laparoscopic ovariectomy was carried out in 33 healthy female in rabbits, which included resection and removal of ovary after clip application, electrocautery of the ovary, then resection, and pulling ovary outside abdomen, ligation by silk, then ovary was removed. The ovaries and associated structures were better visualized by laparoscopy and all three techniques were carried out perfectly. All rabbits after operation were healthy and they were monitored for one month after operation. However, 3 of them died after operation, two of them died due to bleeding and the other of them died due to unknown causes. General anesthesia by using ketamine-xylazine i.m., was suitable for this technique, and the anesthesia provided good analgesia and good muscle relaxation. CO2 was used to establish pneumoperitoneum. In conclusion, resection and removal of the ovaries after clip application technique was found superior to the other two techniques.

Seven patients received interposition grafts in the posterior mandible for implant rehabilitation. The computed tomography cone beam images were analysed with OsiriX Imaging Software 6.5 (Pixmeo Geneva, Switzerland) in the pre-surgical period (T0), at 15 days post-surgery (T1) and at 180 days post-surgery (T2). The tomographic analysis was performed by a single trained and calibrated radiologist. Descriptive statistics and nonparametric methods were used to analyse the data. There was a significant difference in vertical and volume augmentation with both biomaterials using the technique (P  0.05) in volume change of the graft, bone volume augmentation, or augmentation of the maximum linear vertical distance between the two analysed biomaterials. The GEISTLICH BIO-OSS ® and STRAUMANN ® BONECERAMIC interposition grafts exhibited similar and sufficient dimensional stability and volume gain for short implants in the atrophic posterior mandible. © 2016 John Wiley & Sons A/S.

    We report an unusual case of complex giant and large fusiform aneurysms not amenable for clipping or coiling in a 4-year-old child managed with aneurysm resection and radial artery interposition graft. A 4-year-old child presented with repeated severe headache and vomiting. Computed tomography, magnetic resonance imaging, and magnetic resonance angiography and digital subtraction angiography showed a giant fusiform aneurysm on the right middle cerebral artery (MCA). Because of the complex shape, endovascular treatment or clip reconstruction was not possible, and a bypass procedure was planned. Right frontotemporal craniotomy and orbitotomy was performed. Two aneurysms involving the M1 segment of the MCA were found in line, 1 giant, and the other large in size. The aneurysms were resected and treated with short radial artery interposition graft, which was narrower than the proximal or distal MCA. The child recovered normally, and the bypass was patent after 1 year. Large fusiform MCA aneurysms may be difficult to treat, but there are treatment options that include a bypass procedure. Resection and short interposition radial artery graft is an excellent but rare treatment option in a very young child. This was a very successful treatment in this child.

    We report on the functional results of ortho topic modified T pouch ileal neo bladder, incorporating serous- lined extra mural ileal anti reflux technique for urinary diversion after radical cystectomy. Material and Methods: From September 1998 through November 2001,42 patients of mean age 49 years (range 45-54) having invasive bladder carcinoma underwent radical cystectomy and ortho topic ileal neo bladder urinary diversion, the modified T pouch. Thirty-three patients were males while the remaining 9 were females. The mean follow up was 24 months (range 18-42). Preoperative unior bilateral ureteral dilatation was noted in 13/42 (30.9%) patients). Follow up included clinical examination, laboratory, radiological and uro dynamic investigations. Early postoperative complications were recorded in 3 cases, that were managed conservatively. Day and night continence were achieved in 34/42 (81 %) and 29/42 (69%) patients, night enuresis in 2 (4.8%),while satisfactory day and night continence were noted, respectively. Upper urinary tract (UUT) remained unchanged or improved in all cases. No need for clean intermittent catherization (CIC). No evidence of reflux was detected. Pressure at maximum capacity (average 17 cm H 2 O at 600 ml). Mean flow rate was 17.6 ml/sec (range 15-24). Pelvic cancer recurrence was recorded in 5 patients at mean 24 months, respectively. Modified T pouch has an excellent functional criteria as an ortho topic ileal neo bladder reservoir. It is absolutely indicated in short and/or massively dilated ureter

    Full Text Available In 2010, researchers reported that the two US-licensed rotavirus vaccines contained DNA or DNA fragments from porcine circovirus (PCV. Although PCV, a common virus among pigs, is not thought to cause illness in humans, these findings raised several safety concerns. In this study, we sought to determine whether viruses, including PCV, could be detected in ileal tissue samples of children vaccinated with one of the two rotavirus vaccines. A broad spectrum, novel DNA detection technology, the Lawrence Livermore Microbial Detection Array (LLMDA, was utilized, and confirmation of viral pathogens using the polymerase chain reaction (PCR was conducted. The LLMDA technology was recently used to identify PCV from one rotavirus vaccine. Ileal tissue samples were analyzed from 21 subjects, aged 15–62 months. PCV was not detected in any ileal tissue samples by the LLMDA or PCR. LLMDA identified a human rotavirus A from one of the vaccinated subjects, which is likely due to a recent infection from a wild type rotavirus. LLMDA also identified human parechovirus, a common gastroenteritis viral infection, from two subjects. Additionally, LLMDA detected common gastrointestinal bacterial organisms from the Enterobacteriaceae, Bacteroidaceae, and Streptococcaceae families from several subjects. This study provides a survey of viral and bacterial pathogens from pediatric ileal samples, and may shed light on future studies to identify pathogen associations with pediatric vaccinations.

    Side effects and complications of the application of partial ileal bypass used for dislipidemia were analyzed in 162 patients with atherosclerosis. It was shown, that the partial ileal bypass operation could lead to the development of series of undesirable side effects such as diarrhea, hypovitaminosis B12, off-state intestine enteritis. The application of modification of partial ileal bypass such as formation of ileo-ileoanastomosis 5-6 cm long near ileocecal valve with the maintenance of its functions disposed the diarrhea and minimized the risk of the development of hypovitaminosis B12 after operation. It is possible to prevent the development of enteritis of off-state loop of the small intestine by using microanastomosis between off-state and functioning iliac intestine. The partial ileal bypass operation didn't influence on body weight, wouldn't increase the risk of stone formation in the gallbladder and kidneys. The risk of the development of hypovitaminosis B12 is minimal after operation.

    Although the aortic interposition bypass model has been widely used to evaluate biomaterials for bypass grafting, there is no comprehensive description of the procedure or of the distribution of intimal hyperplasia that results. The objectives of this study were to (1) review and summarize approaches of aortic interposition grafting in animal models, (2) determine the pertinent anatomy for this procedure, (3) validate this model in the rat and guinea pig, and (4) compare the distribution of intimal hyperplasia that develops in each species. A literature search was performed in PubMed from 1980 to the present to analyze the use of anesthesia, anticoagulation, antiplatelet agents, graft material, suture, and anastomotic techniques. Using 10-week-old male Sprague-Dawley rats and Hartley guinea pigs, we established pertinent aortic anatomy, developed comparable models, and assessed complications for each model. At 30 days, the graft and associated aorta were explanted, intimal formation was assessed morphometrically, and cellularity was assessed via nuclear counting. We reviewed 30 articles and summarized the pertinent procedural findings. Upon establishing both animal models, key anatomic differences between the species that affect this model were noted. Guinea pigs have a much larger cecum, increased retroperitoneal fat, and lack the iliolumbar vessels compared with the rat. Surgical outcomes for the rat model included a 53% technical success rate and a 32% technical error rate. Surgical outcomes for the guinea pig model included a 69% technical success rate and a 31% technical error rate. These two species demonstrated unique distribution of intimal hyperplasia at 30 days. Intimal hyperplasia in the rat model was greatest at two areas, the proximal graft (5400 μm 2 ; P guinea pig model developed similar intimal hyperplasia throughout the graft (4500-5100 μm 2 ; P guinea pig, and describe a unique distribution of intimal formation that results in both species

    Substantial microbial fermentation may occur mainly in the lower small intestine (SI) of human adults, but there is no established methodology to determine this. The study aimed to develop a combined in vivo and in vitro methodology for ileal fermentation based on the pig as an animal model for digestion in human adults. Several aspects of a combined in vivo/in vitro ileal fermentation assay were evaluated. Male 9-wk-old pigs (n = 30; mean ± SD body weight: 23 ± 1.6 kg) were fed a human-type diet (143, 508, 45, 49, and 116 g/kg dry matter diet of crude protein, starch, total lipid, ash, and total dietary fiber) for 15 d. On day 15, pigs were killed, and the last third of the SI was collected to prepare an ileal digesta-based inoculum. Terminal jejunal digesta (last 50 cm of the second third of the SI) were collected as substrate for the assay to test the form of substrate (fresh or freeze-dried), origin (location in jejunum or SI) of the substrate, storage of the inoculum, incubation time (1.2-6.8 h), pH of the medium, and inoculum concentration (6-26 mg inoculum/100 mg substrate). The group of donor pigs used to prepare the inoculum, form of the substrate, origin of the substrate, origin of the inoculum (location in the SI), storage of the inoculum, incubation time, and inoculum concentration did not influence the in vitro ileal organic matter (OM) fermentability (P > 0.05). The in vitro ileal OM fermentability decreased when the pH of the medium increased from 5.5 to 7.5 (31% to 28%; P ≤ 0.05). Predicted (in vivo/in vitro) apparent ileal OM digestibility was similar to the value measured in vivo. Thirty-percent of the terminal jejunal digesta OM was fermented in the ileum. Fiber fermentation in the ileum can be studied using the optimized in vivo/in vitro ileal fermentation method.

    Full Text Available Objective: Postoperative pouch bleeding is a rare but detrimental complication following ileal pouch surgery. It is usually self-limited, however continuous bleeding requires inter- vention. There is limited published data on its management. Design: Ileoscopy via stoma for loop ileostomy and pouchoscopy via anus for ileal pouch were performed under sedation for the purpose of diagnosis and management of postop- erative bleeding. Results: Ileoscopy demonstrated a large, long blood clot in the lumen of efferent limb, but no sign of active bleeding was identified. Pouchoscopy showed that lumen of pouch body as well as afferent limb was filled with maroon-colored liquid stool. Pouch and neo-terminal ileum mucosa was normal. Two dislodged staples at the anastomotic line with sharp tips towards the lumen were found, with activating bleeding at one site. The staples were re- moved by biopsy forceps, and active bleeding was successfully controlled by the deploy- ment of one endoclip. Conclusions: We reported the first case that postoperative pouch bleeding, which was caused by dislodged staples, was successfully managed by endoscopic removal of the staples com- bined with clipping. Resumo: Objetivo: O sangramento pós-operatório da bolsa ileal é uma complicação rara, mas prejudi- cial após abordagem cirúrgica da bolsa ileal. Esse sangramento é geralmente autolimitado, porém, requer intervenção quando contínuo. Não há dados publicados sobre o tratamento. Método: Ileoscopia através de estoma para ileostomia em alça e endoscopia via ânus para a bolsa ileal foram realizadas sob sedação para diagnóstico e tratamento do sangramento pós-operatório. Resultados: A ileoscopia demonstrou um grande e longo coágulo sanguíneo no lúmen do ramo eferente, mas nenhum sinal de sangramento ativo foi identificado. A endoscopia da bolsa ileal mostrou que os lumens do corpo da bolsa e ramo aferente estavam cheios de fe- zes líquidas de cor marrom. A

    A standard procedure for single-port laparoscopic adrenal surgery has not been established. We retrospectively investigated intraoperative and postoperative outcomes after laparoscopic adrenalectomy through mono port (LAMP) and conventional laparoscopic adrenalectomy to assess the feasibility of LAMP. Between March 2008 and December 2009, 22 patients underwent adrenalectomy at the Department of Surgery, Kangbuk Samsung Hospital. Twelve patients underwent conventional laparoscopic adrenalectomy and 10 patients underwent LAMP. The same surgeon performed all the surgeries. The 2 procedures were compared in terms of tumor size, operating time, time to resumption of a soft diet, length of hospital day, and postoperative complications. The 2 groups were similar in terms of tumor size (30.08 vs. 32.50 mm, P=0.796), mean operating time (112.9 vs. 127 min, P=0.316), time to resumption of a soft diet (1.25 vs. 1.30 d, P=0.805), and length of hospital day (4.08 vs. 4.50 d, P=0.447). Despite 1 patient in the LAMP group experiencing ipsilateral pleural effusion as a postoperative complication, this parameter was similar for the 2 groups (P=0.195). Perioperative mortality, blood transfusion, and conversion to open surgery did not occur. Perioperative outcomes for LAMP were similar to those for conventional laparoscopic adrenalectomy. LAMP appears to be a feasible option for adrenalectomy.

    Thromboelastography (TEG) is a technique that measures coagulation processes and surveys the properties of a viscoelastic blood clot, from its formation to lysis. To determine the possible hypercoagulability state and the effect of antithrombotic prophylaxis on thromboelastogram results and development of venous thrombosis during laparoscopic fundoplication. The study was performed on 106 patients who were randomized into two groups. The first group received low-molecular-weight heparin (LMWH) 12 h before the operation, and 6 and 30 h after it. The second group received LMWH only 1 h before the laparoscopic fundoplication. The TEG profile was collected before LMWH injection, 1 h after the introduction of the laparoscope and 15 min after the surgery was completed. There was no significant difference in thromboelastography R-time between the groups before low-molecular-weight heparin injection. In group I preoperative R-values significantly decreased 1 h after the introduction of the laparoscope, after the end of surgery and on the third postoperative day. K-time values decreased significantly on the third postoperative day compared with the results before low-molecular-weight heparin injection, and after the operation. In group II, preoperative R-values significantly decreased 1 h after the introduction of the laparoscope, and after surgery. K-time values did not change significantly during or after the laparoscopic operation. Our study results demonstrated that the hypercoagulation state (according to the TEG results) was observed during and after laparoscopic fundoplication in patients when LMWH was administered 12 h before the operation together with intraoperative intermittent pneumatic compression. The optimal anticoagulation was obtained when LMWH was administered 1 h before fundoplication.

    To compare three ports laparoscopic cholecystectomy and four ports laparoscopic cholecystectomy in terms of complications, time taken to complete the procedure, hospital stay and cost effectiveness in local perspective. Methodology: This randomized control trial included 60 patients who underwent elective laparoscopic cholecystectomy at Department of Surgery, Pakistan Institute of Medical Sciences, Islamabad, Pakistan from January 2013 to June 2013. These patients were randomized on computer generated table of random numbers into group A and Group B. In Group A patients four ports were passed to perform laparoscopic cholecystectomy and in Group B patients three ports were passed to perform the procedure. Results: The mean age in both groups was 44 years (range 18-72). Three ports laparoscopic cholecystectomy (43 min) took less time to complete than four ports laparoscopic cholecystectomy (51 min). Patients in three ports laparoscopic cholecystectomy experienced less pain as compared to four ports group. The total additional analgesia requirement in 24 hours calculated in milligrams was less in three port laparoscopic cholecystectomy group as compared four port laparoscopic cholecystectomy group. The mean hospital stay in three port laparoscopic cholecystectomy group is 25 hours while the mean hospital stay in the four port laparoscopic cholecystectomy group is 28 hours. Conclusion: Three ports laparoscopic cholecystectomy is safe and effective procedure and it did not compromise the patient safety. (author)

    To determine whether the post-harvest magnetic resonance (MR) imaging appearance of flexor carpi radialis (FCR) tendons, harvested during ligamentous reconstruction tendon interposition (LRTI) of the thumb carpometacarpal (CMC) joint arthroplasty, is consistent with tendon regeneration. Operative reports and patient medical records for all patients undergoing LRTI arthroplasty between 1995 and 2003 at our institution were reviewed. MR images of the patients' forearms and wrists were obtained and interpreted by two musculoskeletal radiologists. Using the flexor carpi ulnaris (FCU) tendon as an internal standard, the extent of FCR tendon regeneration was expressed as a percentage by dividing the volume of regenerated FCR tendon by the volume of the FCU tendon. Fourteen patients who had the full thickness of the FCR tendon harvested and who were available for MR imaging were identified and included in the study. At least partial regeneration of the FCR tendon occurred in 11 of the 14 patients (79%). Of these, 2 patients (14%), demonstrated complete, or nearly complete regeneration. Partial regeneration of the FCR tendon was seen in 9 of the 14 patients (64%). In 3 patients (21%), there was no appreciable regeneration of the FCR tendon. Among patients who underwent full-thickness harvest of the FCR tendon for LRTI arthroplasty of the first CMC joint, the follow-up MR imaging appearance of the flexor carpi radialis tendon was consistent with tendon regeneration in 79% of those examined.

    2009-06-01

    The intestinal derotation technique, introduced by Cattel and Valdoni 40 years ago, is carried out using a laparoscopic procedure, which is described here for the first time. The method is effective in the treatment of malign lesions of the III and IV duodenum and during laparoscopic subtotal colectomy with anastomosis between the ascending colon and the rectum. Ultimately, the procedure allows for the verticalization of the duodenal C and the anterior positioning of the mesenteric vessels, facilitating biopsy and resection of the III and IV duodenal portions and allowing anastomosis of the ascending rectum, avoiding both subtotal colectomy and the risk of torsion of the right colic loop. Although the procedure calls for extensive experience with advanced video-laparoscopic surgery, it is both feasible and repeatable. In our experience we have observed no mortality or morbidity.

    2011-01-01

    In the current age of minimally invasive surgery, laparoscopic surgery for colon cancer has been established as oncologically equivalent to conventional open surgery. The advantages of laparoscopic surgery have translated into smaller incisions and shorter recovery. Since the advent of laparoscopy, surgeons have been fueled to develop less invasive operative methods as feasible alternatives to traditional procedures. As techniques evolved and technology advanced, laparoscopy became more widely accepted and is now more commonly used in many institutions. Recently, a trend toward less invasive surgery, driven by patient and surgeon alike, has been a major objective for many institutions because of the ability of laparoscopic surgery to reduce postoperative pain, achieve a quicker recovery time, and improve cosmetic outcomes. Although still evolving, traditional laparoscopy has served as a foundation for even further refinements in the minimally invasive approach and as a result, more advanced equipment and newer techniques have arisen

    OBJECTIVE: To investigate the frequency and severity of dysphagia during the first 8 weeks after laparoscopic Nissen fundoplication for gastro-oesophageal reflux disease. So far, there have been no studies reporting data on day-to-day occurrence of dysphagia after laparoscopic fundoplication...... in a consecutive series of patients. This may explain why the frequency of dysphagia varies greatly in the literature (4-100%). MATERIAL AND METHODS: Forty consecutive patients, undergoing elective laparoscopic Nissen fundoplication, completed a standard dysphagia registration diary each day during the first 8...... weeks after surgery. Patients who preoperatively had suffered from dysphagia were excluded. Thus, none of the patients had dysphagia in the 2-month period before surgery. Ten patients undergoing elective cholecystectomy served as controls. Data were quantified, and a score value of 4 or more...

    Full Text Available Objective: Most laparoscopic surgeons have attempted to reduce incisional morbidity and improve cosmetic outcomes by using less and smaller trocars. Single incision laparoscopic splenectomy is a new laparoscopic procedure. Herein we would like to present our experiences.Material and Methods: Between January 2009 and June 2009, data of the 7 patients who underwent single incision laparoscopic splenectomy were evaluated retrospectively.Results: There were 7 patients (5 females and 2 males with a mean age of 29.9 years. The most common splenectomy indication was idiopathic thrombocytopenic purpura. Single incision laparoscopic splenectomy was performed successfully in 6 patients. In one patient the operation was converted to an open procedure.Conclusion: With surgeons experienced in minimally invasive surgery, single incision laparoscopic splenectomy could be performed successfully. However, in order to demonstrate the differneces between standard laparoscopic splenectomy and SILS splenetomy, prospective randomized comparative studies are required.

    Enhanced stimulation of the lower gut is hypothesized to play a key role in the weight loss and resolution of diabetes following bariatric surgeries. Ileal transposition (IT) permits study of the effects of direct lower gut stimulation on body weight, glucose homeostasis and other metabolic adaptations without the confounds of gastric restriction or foregut exclusion. However, the underlying mechanisms and the length of the ileum sufficient to produce metabolic benefits following IT surgery remain largely unknown. To determine the effects of transposing varying lengths of the ileum to upper jejunum on food intake, body weight, glucose tolerance and lower gut hormones, and the expression of key markers of glucose and lipid metabolism in skeletal muscle and adipose tissue in rats. Adult male Sprague-Dawley rats (n=9/group) were subjected to IT surgery with translocation of 5, 10 or 20 cm of the ileal segment to proximal jejunum or sham manipulations. Daily food intake and body weight were recorded, and an intraperitoneal glucose tolerance test was performed. Blood samples were assayed for hormones and tissue samples for mRNA (RT-qPCR) and/or protein abundance (immunoblotting) of regulatory metabolic markers. We demonstrate that IT surgery exerts ileal length-dependent effects on multiple parameters including: (1) decreased food intake and weight gain, (2) improved glucose tolerance, (3) increased tissue expression and plasma concentrations of glucagon-like peptide-1 (GLP-1) and peptide YY (PYY), and decreased leptin concentrations and (4) upregulation of key markers of glucose metabolism (glucose transporter-4 (GLUT-4), insulin receptor substrate 1 (IRS-1), adenosine monophosphate-activated protein kinase (AMPK), hexokinase (HK) and phosphofructokinase (PFK)) together with a downregulation of lipogenic markers (fatty acid synthase (FAS)) in muscle and adipose tissue. Together, our data demonstrate that the reduction in food intake and weight gain, increase in lower

    Full Text Available As a first step in firmly establishing laparoscopic hepatectomy, we introduce a porcine model of laparoscopic partial hepatectomy. This procedure has been successfully performed under the normal-pressure or low-pressure pneumoperitoneum condition supported by the full-thickness abdominal wall lifting technique. An ultrasonic dissector combined with electrocautery, newly developed by Olympus Optical Corporation (Japan was effectively utilized in facilitating safe and smooth incisions into the liver parenchyma. Although indications for this procedure seem to be limited only to peripheral lesions and not to central lesions, clinical application of this method may be useful for some patients in the near future.

    The management of gastrointestinal malignancies continues to evolve with the latest available therapeutic and diagnostic modalities. There are currently two driving forces in the management of these cancers: the benefits of minimally invasive surgery so thoroughly demonstrated by laparoscopic surgery, and the shift toward neoadjuvant chemotherapy for upper gastrointestinal cancers. In order to match the appropriate treatment to the disease, accurate staging is imperative. No technological advances have combined these two needs as much as laparascopic ultrasound to evaluate the liver and peritoneal cavity. We present a concise review of the latest application of laparoscopic ultrasound in management of gastrointestinal malignancy.

A package system enables the hospitals to get cost settlements done more easily. Also, it is more convenient for the patients who are aware upfront of the charges. The principal disadvantages seems to be for the surgeon, who may face displeasure of the patient, hospital or insurance agencies apart from forfeiting his personal charges if (a he is a novice in laparoscopic surgery and takes extra time to complete a procedure, (b unforeseen problems occur during surgery, or (c new pathologies are discovered on exploration.

    Full Text Available OBJECTIVE: In this study, we have gathered the second largest series yet published on laparoscopic radical cystectomy in order to evaluate the incidence and cause of intra and postoperative complication, conversion to open surgery, and patient mortality. MATERIALS AND METHODS: From 1997 to 2005, 59 laparoscopic radical cystectomies were performed for the management of bladder cancer at 3 institutions in South America. Twenty nine patients received continent urinary diversion, including 25 orthotopic ileal neobladders and 4 Indiana pouches. Only one case of continent urinary diversion was performed completely intracorporeally. RESULTS: Mean operative time was 337 minutes (150-600. Estimated intraoperative blood loss was 488 mL (50-1500 and 12 patients (20% required blood transfusion. All 7 (12% intraoperative complications were vascular in nature, that is, 1 epigastric vessel injury, 2 injuries to the iliac vessels (1 artery and 1 vein, and 4 bleedings that occurred during the bladder pedicles control. Eighteen (30% postoperative complications (not counting mortalities occurred, including 3 urinary tract infections, 1 pneumonia, 1 wound infection, 5 ileus, 2 persistent chylous drainage, 3 urinary fistulas, and 3 (5% postoperative complications that required surgical intervention (2 hernias - one in the port site and one in the extraction incision, and 1 bowel obstruction. One case (1.7% was electively converted to open surgery due to a larger tumor that precluded proper posterior dissection. Two mortalities (3.3% occurred in this series, one early mortality due to uncontrolled upper gastrointestinal bleeding and one late mortality following massive pulmonary embolism. CONCLUSIONS: Laparoscopic radical cystectomy is a safe operation with morbidity and mortality rates comparable to the open surgery.

  20. How I do it: the stapled ileal J pouch at restorative proctocolectomy.

    Ileal pouch-anal anastomosis (IPAA) following proctocolectomy is the preferred option for patients with medically refractory ulcerative colitis, indeterminate colitis, and familial adenomatous polyposis. However, it remains a procedure associated with morbidity and mortality. Pelvic sepsis, pouch fistulae, and anastomotic dehiscence predispose to pouch failure. We report our experience with an adaptation for the formation of the stapled ileal J pouch using the GIA™ 100 stapling device (Covidien, Mansfield, Massachusetts, USA). When creating the J pouch, we remove the bevelled plastic protector from the thin fork of the stapling device, allowing the staple line to be completed to the tip of the stapled efferent limb of the pouch, thereby minimizing potential blind ending in the efferent limb and injury to the transverse staple line.

    1996-01-01

    To investigate specific plasma membrane structural changes associated with apoptosis, whole cells and purified plasma membranes of apoptotic B cells from the ileal Peyer's patch of sheep were analyzed for their 'membrane fluidity'. The ileal Peyer's patch of sheep provided a large number of B cells required for plasma membrane isolation (>5 x 10 9 ). As the incidence of apoptosis increased with time of culture, the fluidity of purified plasma membranes, as measured with the fluorophore DPH (diphenylhexatriene), increased. To evaluate this phenomenon with intact cells, B cells at different apoptotic stages were fractionated on discontinuous Percoll gradients. Similar results were obtained using the fluorophore TMA-DPH (trimethylammoniumdiphenylhexatriene), which has been shown to localize specifically to the plasma membrane. Functionally, the increase in plasma membrane fluidity associated with apoptosis may represent either a mechanism to cycle phosphatidylserine to the outer leaflet, mediating phagocytic recognition of apoptotic cells, or a consequence of this event.

    Billroth-I (BI) is a simple, physiological method of reconstruction following distal gastrectomy. In actuality, postoperative QOL is by no means favorable due to the high incidence of post-gastrectomy syndrome. The aim of this study is to assess the safety and efficacy of boomerang-shaped jejunal interposition (BJI) after distal gastrectomy. Sixty-six patients with early gastric cancer underwent the BI procedure (n = 33) or BJI (n = 33) after distal gastrectomy, following which they were compared for 5 years. Tumor characteristics, operative details, postoperative complications and complaints, number of meals, and body weight were analyzed. Patients were followed up by endoscopy every 12 months. There were no significant differences in the incidence of postoperative complications. The incidence of heartburn (30 vs. 0 %, P = 0.0009) and oral bitterness (33 vs. 6 %, P = 0.0112) were significantly lower in the BJI cases. Endoscopic findings revealed significantly lower incidences of reflux esophagitis (24 vs. 0 %, P = 0.0051) and remnant gastritis (70 vs. 3 %, P < 0.0001) in the BJI group. The incidence of food stasis was low in both groups (12 vs. 15 %). In the BJI group, 30 patients (90 %) were eating 3 meals/day within 12 months, whereas in the BI group, 16 patients (48 %) were still eating 5 meals/day at 12 months or later. BJI is as safe as BI, but is better in terms of improvement in bile reflux and food intake without stasis. This procedure, therefore, appears to be a useful method for reconstruction after distal gastrectomy.

    We performed an interposition arthroplasty using the abductor pollicis longus tendon for arthrosis in the basal joint of the thumb that needed surgery from 1995 to 2010. In 2001 47 patients (55 thumbs) were reviewed after 3.5 (1-5) years. The pain relief was excellent in 32 thumbs, and 25 patients improved their ability to perform daily tasks. Mobility was well preserved. Key pinch and grip strengths averaged 78% and 89%, respectively, of those in unaffected hands. We have now re-examined all 33 available patients (36 thumbs) 11-14 years after surgery. Fourty one of the originally examined patients were still alive. Seven were too ill to attend a follow-up and one refused. The remainder were examined in a fashion as similar as possible to that at the original review. The patients' subjective estimations of pain during the last week and satisfaction with the cosmetic and general results were recorded on visual analogue scales. The patients' ability to perform various activities of daily living were recorded and they completed the Disability of the arm, shoulder and hand (DASH) questionnaire. The mobility of the wrist and abduction of the thumb of the operated hands were recorded with a goniometer. Grip and pinch strength were measured and new radiographs were obtained. Key pinch strength had increased significantly over the last 10 years. The mobility was still good, except for thumb abduction, which had decreased with time. The median DASH score had fallen from 28 to 20 between the two reviews. There was insignificant further median loss of distance between the scaphoid and the metacarpal since the earlier review. The good results of this procedure found soon after surgery are maintained long-term.

    Retrograde ureteric catheterization of a patient with an ileal conduit is difficult, because guide wires and catheters coil in the conduit. A modified loopogram, using a Foley catheter as a fulcrum through which catheters can be advanced to the ureteric anastomosis, is described. This technique was used to remove a JJ stent, which had been inserted previously across a stricture in one ureter, the stent crossing from one kidney to the other.

    Full Text Available Zinc oxide nanoparticles (ZnO NPs are used widely in consumer and industrial products, however, their influence on gut microbiota and metabolism and their mutual interactions are not fully understood. In this study, the effects of ZnO NPs on ileal bacterial communities, plasma metabolites, and correlations between them were investigated. Hens were fed with different concentrations of ZnO NPs [based on Zn; 0 mg/kg (control, 25 mg/kg, 50 mg/kg, and 100 mg/kg] for 9 weeks. Subsequently, ileal digesta and blood plasma were collected for analysis of microflora and metabolites, respectively. The V3-V4 region of the 16S rRNA gene of ileal digesta microbiota was sequenced using the Illumina HiSeq 2500 platform. The predominant bacterial community in the ileum belongs to the phylum Firmicutes. The richness of the bacterial community was negatively correlated with increasing amounts of ZnO NPs (r = -0.636, P < 0.01; when ZnO NP levels were at 100 mg/kg, microbiota diversity was significantly decreased (P < 0.05. The community structure determined by LEfSe analysis indicated that Bacilli, Fusobacteria, and Proteobacteria were changed, and Lactobacillus was reduced by ZnO NPs. Moreover, metabolism as analyzed by nuclear magnetic resonance (NMR indicated that glucose, some amino acids, and other metabolites were changed by ZnO NPs. Choline, lactate, and methionine were positively correlated with bacterial richness. In summary, ZnO NPs could influence the levels of microflora in ileal digesta, particularly Lactobacillus. Furthermore, the richness of the microbiota was related to changes in choline, lactate, and methionine metabolism.

    Objective was to revise indications, case fatality ratio, and postoperative early and late complications of ileal conduit as a method of urinary diversion. This is a retrospective study in which 200 patients underwent an ileal conduit from August 1994 to December 2000 in Mansoura Urology and Nephrology Center, Mansoura, Egypt. Preoperative criteria of patient selection, preoperative findings and postoperative follow-up data were reviewed. In 200 patients aged 29-75 years, with a mean age of 55.84-/+ 8.91 years, the ileal conduit was chosen as a method of urinary diversion, due to one of the following patient or surgical factors; 50 (25%) cardiopulmonary co-morbidities, 27(13.5%) liver cirrhosis, 20 (10%) impaired renal function, 18 (9%) poorly controlled diabetes mellitus and 3 (1.5%) morbid obesity. Frozen section pathological examination showed carcinoma invasion of the urethra in 26 (13%) and prostate stroma in 16 (8%) male patients. Severe adhesions and difficulty cystectomy were encountered in 25 (12.5%) patients. Tumor was found at or close to the bladder neck in 13 (6.5%) female patients and 2 (1%) patients were found to have short mesentery. The mean follow up period was 90.02 -/+ 22.63 months. Fatality rate was 2%. Twenty-three (11.5%) patients had early complications, while 36 (23.7%) patients had late complications. Ileal conduit is still the best urinary diversion method in many patients who have bladder cancer with associated chronic medical disease or certain surgical factors that render other urinary diversion methods more difficult carry more postoperative morbidity and mortality or both.

    Full Text Available The incidence of blunt abdominal trauma has increased in recent years; however, relatively little attention has been paid to instances of its sequelae, especially in childhood. Small bowel stricture following a history of abdominal trauma is a rare cause of small bowel obstruction and there have been few reports examining its occurrence. We are presenting here a case of posttraumatic double ileal stenosis in a 4-year female child.

    To quantitatively assess microvascular activation in the thickened ileal walls of patients with Crohn disease (CD) by using contrast-enhanced ultrasonography (US) and evaluate its correlation with widely used indexes of CD activity. This prospective study was approved by the ethics committee, and written informed consent was obtained from all patients. The authors examined 54 consecutively enrolled patients (mean age, 35.29 years; age range, 18-69 years; 39 men, 15 women) with endoscopically confirmed CD of the terminal ileum. Ileal wall segments thicker than 3 mm were examined with low-mechanical-index contrast-enhanced US and a second-generation US contrast agent. The authors analyzed software-plotted time-enhancement intensity curves to determine the maximum peak intensity (MPI) and wash-in slope coefficient (β) and evaluated their correlation with (a) the composite index of CD activity (CICDA), (b) the CD activity index (CDAI), and (c) the simplified endoscopic score for CD (SES-CD, evaluated in 37 patients) for the terminal ileum. Statistical analysis was performed with the Mann-Whitney test, Spearman rank test, and receiver operating characteristic (ROC) analysis. MPI and β coefficients were significantly increased in the 36 patients with a CICDA indicative of active disease (P<.0001 for both), the 33 patients with a CDAI of at least 150 (P<.032 and P<.0074, respectively), and the 26 patients with an SES-CD of at least 1 (P<.0001 and P<.002, respectively). ROC analysis revealed accurate identification (compared with CICDA) of active CD with an MPI threshold of 24 video intensity (VI) (sensitivity, 97%; specificity, 83%) and a β coefficient of 4.5 VI/sec (sensitivity, 86%; specificity, 83%). Contrast-enhanced US of the ileal wall is a promising method for objective, reproducible assessment of disease activity in patients with ileal CD. © RSNA, 2011

    Full Text Available The objective of this experiment was to determine the concentration and digestibility of crude protein (CP and amino acid (AA in meat meal (MM, and to compare these values with the respective values in soybean meal (SBM. Six barrows (initial body weight = 66.9±3.8 kg surgically fitted with a T-cannula at the distal ileum were allotted to a replicated 3×3 balanced Latin square design with 3 diets and 3 periods. Two experimental diets containing test ingredients as the sole source of AA were prepared to estimate the apparent ileal digestibility (AID for CP and AA by the direct method. An N-free diet was also prepared to estimate basal endogenous losses of CP and AA. All experimental diets contained 5% chromic oxide as an indigestible index. Each period consisted of a 5-d adaptation period and a 2-d of ileal digesta collection period. Ileal digesta samples were collected from 0900 to 1700 on d 6 and 7 of each period. The concentrations of CP, Lys, Met, and Trp in MM and SBM were analyzed to be 64.1, 3.5, 1.1 and 0.6, and 45.6, 2.8, 0.8, and 0.3%, respectively. The AID of all AA except Gly in MM was less (p<0.05 than in SBM. The AID of Lys, Met, and Trp in MM was estimated to be 56.0, 71.7, and 47.1%, respectively. The SID of all AA in MM was less (p<0.05 than in SBM. The SID of Lys, Met, and Trp was 65.1, 79.2, and 78.5%, respectively. In conclusion, the CP and AA contents in MM were greater than those in SBM whereas the ileal digestibility of all AA in MM was less than in SBM.

    Purpose: Radical trachelectomy is a fertility-sparing procedure with the aim to provide adequate oncological safety to patients with cervical cancer while preserving their fertility. The purpose of this study was to retrospectively evaluate, in a series of 3 patients, the feasibility, morbidity, and safety of laparoscopically assisted vaginal radical trachelectomy for early cervical cancer. Patients and Methods: Three non consecutive patients with FIGO stage IA1 and IB1 cervical cancer was evaluated in a period of years 2008 - 2011. The patients underwent a laparoscopic pelvic lymphadenectomy and radical parametrectomy class II procedure according to the Piver classification. The section of vaginal cuff, trachelectomy, permanent cerclage and isthmo-vaginal anastomosis ware realised by vaginal approach. Results: The median operative time, the median blood loss and the mean number of resected pelvic nodes was comparable with published data. Major intraoperative complications did not occur and no patient required a blood transfusion. The median follow-up time was 33 (38-59) months. One vaginal recurrence occurred in 7 months after primary surgery. The patient was underwent a radicalisation procedure and adjuvant oncologic therapy and now is free of disease. Conclusions: Laparoscopically assisted vaginal radical trachelectomy (LAVRT)may be an alternative in fertility-preserving surgery for early cervical cancer. The procedure offers patients potential benefits of minimally invasive surgery with adequate oncological safety, but it should be reserved for oncologic surgeons trained in advanced laparoscopic procedures.

    Epiphrenic diverticula (ED) are a rare clinical entity characterized by out-pouchings of the esophageal mucosa originating in the distal third of the esophagus, close to the diaphragm. The proportion of diverticula reported symptomatic enough to warrant surgery is extremely variable, ranging from 0% to 40%. The natural history of ED is still almost unknown and the most intriguing question concerns whether or not they all need surgical treatment. From 1993 to 2010 35 patients underwent surgery at our institution. Eleven patients were treated via a thoracotomic approach alone and were excluded from present study. The remaining 24 patients formed our study population. Seventeen patients (48.6%) underwent surgery via a purely laparoscopic approach, and received a diverticulectomy + myotomy + antireflux procedure. Seven patients (23%), with ED positioned well above inferior pulmonary vein, were treated via a combined laparoscopic-thoracotomic approach: they all underwent diverticulectomy + myotomy + an antireflux procedure. Mortality was nil. The overall morbidity rate was 25%. A suture leakage occurred in 4 patients (16.6%) and they were all conservatively treated. Patients' symptom scores decreased from a median of 15 to 0 (P = 0.0005). Laparoscopic surgery for ED is effective, but given the not negligible incidence of complications such suture-line leakage, should be considered only in symptomatic patients or in event of huge diverticula. A tailored combined laparoscopic-thoracotomic approach may be useful in case of ED located high in mediastinum or with large neck. Copyright © 2012 Elsevier Inc. All rights reserved.

    We describe the feasibility and short-term results of laparoscopic transureteroureterostomy in children. We performed transperitoneal laparoscopic transureteroureterostomy with a 4-trocar technique in 3 children with a mean age of 63 months (range 18 to 105). Diagnoses were unilateral ureteral obstruction after cross-trigonal reimplantation for vesicoureteral reflux (1 patient), unilateral refluxing megaureter (1) and ureteral injury after bladder diverticulectomy (1). Cystoscopy, retrograde pyelogram and stent placement in the recipient ureter were performed at the beginning of each case. The anastomoses were carried out with running 6-zero reabsorbable sutures at the level of the pelvic bream. An abdominal drain and Foley catheter were left indwelling for 1 to 3 days. All cases were performed successfully. Postoperative course was uneventful except for a transient urinary leak, and patients were discharged home on postoperative day 2 to 4. At a mean followup of 6 months all patients were clinically well, with normal kidney function and blood pressure, and no significant hydronephrosis. Based on our initial experience, laparoscopic transureteroureterostomy is safe and effective, and is associated with little blood loss, minimal analgesia requirements, fast recovery and excellent cosmetic results. We believe that in selected cases in which transureteroureterostomy is the chosen technique a laparoscopic approach is advantageous.

    Full Text Available Background. In laparoscopic surgery errors are unavoidable and require proper acknowledgment to reduce the risk of intraoperative and accurately assess the appropriate therapeutic approach. Fortunately, their frequency is low and cannot overshadow the benefits of laparoscopic surgery. Materials and Methods. We made an epidemiological investigation in General Surgery Department of Emergency Clinical Hospital "St. John" Bucharest, analyzing 20 years of experience in laparoscopic surgery, during 1994-2014. We wanted to identify evolution trends in complications of laparoscopic surgery, analyzing the dynamic of errors occurred in all patients with laparoscopic procedures. Results. We recorded 26847 laparoscopic interventions with a total of 427 intra-or postoperative complications that required 160 conversions and 267 reinterventions to resolve inconsistencies. The average frequency of occurrence of complications was 15.9‰ (15.9 of 1,000 cases. In the period under review it was a good momentum of laparoscopic procedures in our department. Number of minimally invasive interventions increased almost 10 times, from 266 cases operated laparoscopically in 1995 to 2638 cases in 2008. Annual growth of the number of laparoscopic procedures has surpassed the number of complications. Conclusions. Laborious work of laparoscopic surgery and a specialized centre with well-trained team of surgeons provide premises for a good performance even in the assimilation of new and difficult procedures.

    An interaction between Ca ++ -channel antagonists and the α 2 -adrenergic receptor on active electrolyte transport was demonstrated in rabbit ileum. Clonidine, an α 2 -agonist, stimulated NaCl absorption apparently by Ca ++ -channel antagonism since it inhibited 45 Ca ++ uptake across the basolateral membrane and decreased total ileal calcium content. This stimulation was inhibited by the Ca ++ -channel antagonists dl- and l-verapamil and cadmium but not by nifedipine. The binding of 3 H-yohimbine, a specific α 2 -adrenergic antagonist, was studied on purified ileal cell membranes using a rapid filtration technique. dl-Verapamil and Cd ++ inhibited the specific binding of 3 H-yohimbine over the same concentration range in which they affected transport. In contrast, nifedipine had no effect on binding, just as it had no effect on clonidine-stimulated NaCl absorption. These data demonstrate that there is an interaction between Ca ++ -channels and α 2 -adrenergic receptors in ileal basolateral membranes. Some Ca ++ -channel antagonists alter α 2 -adrenergic binding to the receptor and α 2 -agonist binding leads to changes in Ca ++ entry. A close spatial relationship between the Ca ++ -channel and the α 2 -receptor could explain the data

  3. An unusual case of giant ileal diverticulum–A case report

    Full Text Available Small bowel diverticulosis is rare with an incidence of 1–2% in the general population. It is an uncommon cause of gastrointestinal bleeding that ranges from obscure to overt bleeding. Large ileal diverticula are extremely rare and bleeding complications can result in high overall mortality.A young gentleman presented with persistent per-rectal bleeding and drop in hemoglobin level. He was recently diagnosed with acute myeloid leukemia and was undergoing chemotherapy. A computed tomography scan of the abdomen and pelvis revealed a giant ileal diverticulum. In view of on-going bleeding, he underwent double balloon enteroscopy which revealed active bleeding from an ulcer within the giant ileal diverticulum and successful hemostasis was performed with hemostatic clips.Small bowel diverticulosis though uncommon has to be considered during workup for gastrointestinal bleeding. Endoscopic treatment is a modern approach towards small bowel diverticular bleeding that is effective and less invasive.

    2000-06-01

    Full Text Available The effects of four protein sources (soybean meal, sunflower meal, pea and fish meal as the main protein source were investigated on fattening performance, carcass and meat quality traits and body composition of pigs. Eight animals per treatment received the diets from 30 to 105 kg live weight at a level of 3.0 times maintenance requirement of energy. Diets were formulated on the basis of ileal digestible protein and amino acid content of feedstuffs. Protein sources resulted similar fattening performance from 30-105 kg body weight. From 30 to 60 kg soybean treatment had lowest performance. The protein source treatments did not alter the body composition, lean meat percentage, liver weight and meat quality (intramuscular fat content, pH 45 min and 24 hours after slaughter, drip loss, meat lightness and hue measured 24 hours and 4 days after slaughter. It can be concluded that protein sources can be replaced without affecting overall fattening performance, carcass and meat quality and body composition if diet formulation is based on the ileal digestible amino acid contents of feedstuffs. However the lower performance of the soybean treatment in the first phase may indicate that ileal digestible Lys content of heat treated protein sources may not characterise the feedstuffs well enough. It may be that young pigs are more sensitive to unavailable lysine by the way.

    Intestinal occlusion due to intussusception produced by intestinal tumors is a very rare condition. Gastrointestinal stromal tumors are also rare digestive neopasias, with an impredictable malignant behavior, which are usually growing outside the intestinal wall, being rarely the initiators of an intestinal intussusception. We present the case of a 59 years old female, admitted in our hospital to elucidate the etiology of her iron deficient anaemia, which developed an intestinal occlusion at the intestinal preparation for colonoscopy. The abdominal CT scan performed in emergency conditions highlighted occlusive intestinal tumor complicated with intestinal intussusception. We performed an emergency laparotomy that revealed intestinal occlusion due to ileo-ileal intussusception produced by an ileal tumor. The surgical intervention consisted in segmental ileal enterectomy including the tumor with latero-lateral entero-enteral anastomosis. The patient recovered without complications. The histopathological and immunohisto-chemical examinations established the diagnose of gastro-intestinal stromal tumor with high risk malignant behavior, therefore the patient was guided in the oncological department for specific treatment and oncological surveillance.

    Injury to the small intestine from pelvic irradiation increases in frequency when extended treatment fields are utilized and when radiation therapy follows a major abdominal operation. Recommended surgical correction of such injury has been intestinal bypass to avoid the excessive morbidity and mortality from anastamotic leaks associated with primary resection and anastomosis. Since 1980, eight patients with extensive ileal injury secondary to irradiation have been seen at the Naval Hospital Bethesda, Maryland. All patients had previously undergone an abdominal operation and three patients had irradiation utilizing extended fields. In all cases, right hemicolectomy and extended ileal resection were performed with primary anastamosis of the ileum to the ascending colon or the transverse colon. Operating time averaged 4 1/2 hr utilizing hand closure anastomoses and 2 1/2 hr with stapled anastomoses. All patients received postoperative hyperalimentation and six of eight patients received preoperative hyperalimentation. One operative death occurred in a patient with intestinal perforation who required multiple resections. The remaining seven patients experienced no serious complications and had rapid return of bowel function. Our experience indicates that wide ileal resection with right hemicolectomy and primary reanastomosis is an acceptable alternative to intestinal bypass for the treatment of severe irradiation injury, especially when performed with gastrointestinal stapling devices

Recommended surgical correction of such injury has been intestinal bypass to avoid the excessive morbidity and mortality from anastamotic leaks associated with primary resection and anastomosis. Since 1980, eight patients with extensive ileal injury secondary to irradiation have been seen at the Naval Hospital Bethesda, Maryland. All patients had previously undergone an abdominal operation and three patients had irradiation utilizing extended fields. In all cases, right hemicolectomy and extended ileal resection were performed with primary anastamosis of the ileum to the ascending colon or the transverse colon. Operating time averaged 4 1/2 hr utilizing hand closure anastomoses and 2 1/2 hr with stapled anastomoses. All patients received postoperative hyperalimentation and six of eight patients received preoperative hyperalimentation. One operative death occurred in a patient with intestinal perforation who required multiple resections. The remaining seven patients experienced no serious complications and had rapid return of bowel function. Our experience indicates that wide ileal resection with right hemicolectomy and primary reanastomosis is an acceptable alternative to intestinal bypass for the treatment of severe irradiation injury, especially when performed with gastrointestinal stapling devices.

    Full Text Available ABSTRACT Objective: The purpose of this video is to present the laparoscopic repair of a VUF in a 42-year-old woman, with gross hematuria, in the immediate postoperative phase following a cesarean delivery. The obstetric team implemented conservative management, including Foley catheter insertion, for 2 weeks. She subsequently developed intermittent hematuria and cystitis. The urology team was consulted 15 days after cesarean delivery. Cystoscopy indicated an ulcerated lesion in the bladder dome of approximately 1.0cm in size. Hysterosalpingography and a pelvic computed tomography scan indicated a fistula. Materials and Methods: Laparoscopic repair was performed 30 days after the cesarean delivery. The patient was placed in the lithotomy position while also in an extreme Trendelenburg position. Pneumoperitoneum was established using a Veress needle in the midline infra-umbilical region, and a primary 11-mm port was inserted. Another 11-mm port was inserted exactly between the left superior iliac spine and the umbilicus. Two other 5-mm ports were established under laparoscopic guidance in the iliac fossa on both sides. The omental adhesions in the pelvis were carefully released and the peritoneum between the bladder and uterus was incised via cautery. Limited cystotomy was performed, and the specific sites of the fistula and the ureteral meatus were identified; thereafter, the posterior bladder wall was adequately mobilized away from the uterus. The uterine rent was then closed using single 3/0Vicryl sutures and two-layer watertight closure of the urinary bladder was achieved by using 3/0Vicryl sutures. An omental flap was mobilized and inserted between the uterus and the urinary bladder, and was fixed using two 3/0Vicryl sutures, followed by tube drain insertion. Results: The operative time was 140 min, whereas the blood loss was 100ml. The patient was discharged 3 days after surgery, and the catheter was removed 12 days after surgery

    Full Text Available Leiomyosarcoma of inferior vena cava (IVC involving bilateral renal veins presents a surgical challenge. Herein, we report the successful management of two such cases using restoration of left renal venous outflow by saphenous vein interposition graft as first step of surgery. Then radical resection of tumor and right kidney was done. IVC was lastly reconstructed using Gore-Tex graft. This report highlights the surgical challenges to ensure radical resection. Furthermore, the importance of restoring left renal outflow in presence of concomitant right nephrectomy is discussed. Both the patients were disease free at six months with no loss of left renal glomerular filtration rate.

    Birth rates in males with ulcerative colitis and ileal pouch-anal anastomosis have not been studied. This study aimed to estimate birth rates in males and females with ulcerative colitis and study the impact of ileal pouch-anal anastomosis. This was a retrospective registry-based cohort study that was performed over a 30-year period. Records for parenting a child from the same period were cross-linked with patient records, and birth rates were calculated using 15 through 49 years as age limits. All data were prospectively registered. All patients with ulcerative colitis and ulcerative colitis with ileal pouch-anal anastomosis between 1980 and 2010 were identified in Danish national databases. The primary outcomes measured were birth rates in females and males with ulcerative colitis and ulcerative colitis with ileal pouch-anal anastomosis. We included 27,379 patients with ulcerative colitis (12,812 males and 14,567 females); 1544 had ileal pouch-anal anastomosis (792 males and 752 females). Patients with ulcerative colitis have slightly reduced birth rates (males at 40.8 children/1000 years, background population 43.2, females at 46.2 children/1000 years, background population 49.1). After ileal pouch-anal anastomosis, males had increased birth rates at 47.8 children/1000 years in comparison with males with ulcerative colitis without ileal pouch-anal anastomosis (40.5 children/1000 years), whereas females had reduced birth rates at 27.6 children/1000 years in comparison with females with ulcerative colitis without ileal pouch-anal anastomosis (46.8 children/1000 years). Only birth rates were investigated and not fecundability. Furthermore, there is a question about misattributed paternity, but this has previously been shown to be less than 5%. Ulcerative colitis per se has little impact on birth rates in both sexes, but ileal pouch-anal anastomosis surgery leads to a reduction in birth rates in females and an increase in birth rates in males. This has clinical

    Laparoscopic resection of transverse colon carcinoma is technically demanding and was excluded from most of the large trials of laparoscopic colectomy. The aim of this study was to assess the safety, feasibility, and outcome of laparoscopic resection of carcinoma of the transverse colon. A retrospective review was performed to identify patients who underwent laparoscopic resection of transverse colon carcinoma. These patients were compared to patients who had laparoscopic resection for right and sigmoid colon carcinoma. In addition, they were compared to a historical series of patients who underwent open resection for transverse colon cancer. A total of 22 patients underwent laparoscopic resection for transverse colon carcinoma. Sixty-eight patients operated for right colon cancer and 64 operated for sigmoid colon cancer served as comparison groups. Twenty-four patients were identified for the historical open group. Intraoperative complications occurred in 4.5% of patients with transverse colon cancer compared to 5.9% (P = 1.0) and 7.8% (P = 1.0) of patients with right and sigmoid colon cancer, respectively. The early postoperative complication rate was 45, 50 (P = 1.0), and 37.5% (P = 0.22) in the three groups, respectively. Conversion was required in 1 (5%) patient in the laparoscopic transverse colon group. The conversion rate and late complications were not significantly different in the three groups. There was no significant difference in the number of lymph nodes harvested in the laparoscopic and open groups. Operative time was significantly longer in the laparoscopic transverse colectomy group when compared to all other groups (P = 0.001, 0.008, and transverse colectomy, respectively). The results of laparoscopic colon resection for transverse colon carcinoma are comparable to the results of laparoscopic resection of right or sigmoid colon cancer and open resection of transverse colon carcinoma. These results suggest that laparoscopic resection of transverse

    Full Text Available Background. The optimal surgical treatment for Kienböck’s disease with stages IIIB and IV remains controversial. A cadaver study was carried out to evaluate the use of coiled extensor carpi radialis longus tendon for tendon interposition and a strip obtained from the same tendon for ligament reconstruction in the late stages of Kienböck’s disease. Methods. Coiled extensor carpi radialis longus tendon was used to fill the cavity of the excised lunate, and a strip obtained from this tendon was sutured onto itself after passing through the scaphoid and the triquetrum acting as a ligament to preserve proximal row integrity. Biomechanical tests were carried out in order to evaluate this new ligamentous reconstruction. Results. It was biomechanically confirmed that the procedure was effective against axial compression and distributed the upcoming mechanical stress to the distal row. Conclusion. Extensor carpi radialis longus tendon has not been used for tendon interposition and ligament reconstruction in the treatment of this disease before. In view of the biomechanical data, the procedure seems to be effective for the stabilization of scaphoid and carpal bones.

    1993-01-01

    An ultrasound dissector especially developed for laparoscopic surgery was used during laparoscopic cholecystectomy on 34 patients. The ultrasound power, the volume of suction and irrigation could be determined individually at the generator and activated during the operation with a foot pedal. With the dissector it was possible to fragmentate, emulgate and aspirate simultaneously fat tissue as well as infected edematous structures. The cystic artery and cystic duct, small vessels, lymphatic and connective tissue were not damaged. Therefore this system seems to be excellent for the preparation of Calot's trigonum and blunt dissection of the gallbladder out of its bed, particularly in fatty, acute or chronic infected tissue. No complications were observed within the peri- and postoperative period.

    The B lymphocyte-epithelial cell interactions that define the microenvironment of the ileal Peyer's patch, the primary B lymphocyte organ of the fetal lamb, have been replicated in tissue culture. Mixed suspensions of ileal epithelial cells, lymphocytes and fibroblasts from fetuses of 63-103 days of gestation organized into macroscopically visible agglomerates within 72 h. These agglomerates contained translucent spherical cavities and were enclosed within a marginal cell layer and surrounded by an expanding corona of emigrating cells. The lining of the cavities and the marginal layer consisted of well-differentiated, polarized columnar ileal epithelial cells. One population of B lymphocytes in the initial mixed suspension differentiated into two discrete populations reproducing the characteristics of intact fetal ileal Peyer's patches. B cells apposed to follicle-associated epithelium (FAE) within agglomerates underwent apoptosis. The other population of emigrant B cells proliferated and expressed the BAQ44A differentiation marker. Differentiation of ileal epithelial cells into FAE, typical of Peyer's patches, was markedly accelerated. The mutually inductive influences of intestinal epithelial cells and B lymphocytes in these agglomerates replicate normal mid-gestational fetal development of the mucosal immune system and afford new opportunities for its further investigation.

    External biliary fistula (BF) or ileal bypass (IB) was performed in dogs at the time of or 2 weeks after portacaval shunt (PCS). The pathologic changes in the dog livers 2 to 4 weeks later were compared to those caused by PCS alone. Histopathologic differences between PCS alone vs. PCS plus BF or IB could not be found. Thus, the experiments did not confirm recent observations by others in rats that BF prevents or reverses the hepatic injury of PCS. As estimated by plasma mevalonic acid determinations, the increase in hepatic cholesterol synthesis that is characteristic after BF or IB was suppressed in animals with PCS. BF and IB reduced but did not eliminate the postprandial elevation in serum bile acid that occurs after PCS. The findings have possible relevance in planning the treatment of patients with familial hypercholesterolemia with the combined use of PCS and IB. PMID:6862371

    Laparoscopic cholecystectomy has undergone an explosive growth. Its benefits to patients--shortened recovery time and less pain--became immediately obvious. The procedure's development and adaptation have largely been devised and implemented by ingenious and creative private practitioners, not the typical mode of introduction. Most or many new procedures in the past evolved from academic institutions after laboratory and then clinical trials. With rapid development and acceptance has come an additional new burden among medical practitioners: credentialing and granting clinical privileges.

    The application of minimally invasive approaches to pancreatic resection for benign and malignant diseases has been growing in the last two decades. Studies have demonstrated that laparoscopic distal pancreatectomy (LDP) is feasible and safe, and many of them show that compared to open distal pancreatectomy, LDP has decreased blood loss and length of hospital stay, and equivalent post-operative complication rates and short-term oncologic outcomes. LDP is becoming the procedure of choice for benign or small low-grade malignant lesions in the distal pancreas. Minimally invasive pancreaticoduodenectomy (MIPD) has not yet been widely adopted. There is no clear evidence in favor of MIPD over open pancreaticoduodenectomy in operative time, blood loss, length of stay or rate of complications. Robotic surgery has recently been applied to pancreatectomy, and many of the advantages of laparoscopy over open surgery have been observed in robotic surgery. Laparoscopic enucleation is considered safe for patients with small, benign or low-grade malignant lesions of the pancreas that is amenable to parenchyma-preserving procedure. As surgeons’ experience with advanced laparoscopic and robotic skills has been growing around the world, new innovations and breakthrough in minimally invasive pancreatic procedures will evolve.

    Morbid obesity, defined as a body mass index (BMI), i.e. weight (kg)/height (m2) over 36 for males and 38 for females, is a common condition and a threat for health, life and individual well being. Hitherto, surgery is the only effective treatment for weight reduction. Surgical methods can be malabsorptive, reducing the patients ability to absorb nutrients, or restrictive, reducing the capacity of food intake. Exclusively malabsorptive methods have been abandoned due to severe side effects. Restrictive methods, gastroplasties, reduces the compliance capacity of the stomach. Two types are performed laparoscopically, the vertical banded gastroplasty and the adjustable gastric banding. The proximal gastric by pass is also performed laparoscopically and is a combination of a restrictive proximal gastroplasty and a malabsorptive Roux-en-Y gastro-jejunal anastomosis. With laparoscopic adjustable gastric banding mean BMI was reduced from 41 kg/m2 to 33 kg/m2 (n = 43) after one year. Two years after surgery mean BMI was 30 kg/m2 (n = 16). The different operative techniques are further discussed in this paper.

    Laparoscopic adhesiolysis has been demonstrated to be technically feasible in small bowel obstruction and carries advantages in terms of post-surgical course. The increasing dissemination of laparoscopic surgery in the emergency setting and the lack of concrete evidence in the literature have called for a consensus conference to draw recommendations for clinical practice. A literature search was used to outline the evidence, and a consensus conference was held between experts in the field. A survey of international experts added expertise to the debate. A public jury of surgeons discussed and validated the statements, and the entire process was reviewed by three external experts. Recommendations concern the diagnostic evaluation, the timing of the operation, the selection of patients, the induction of the pneumoperitoneum, the removal of the cause of obstructions, the criteria for conversion, the use of adhesion-preventing agents, the need for high-technology dissection instruments and behaviour in the case of misdiagnosed hernia or the need for bowel resection. Evidence of this kind of surgery is scanty because of the absence of randomized controlled trials. Nevertheless laparoscopic skills in emergency are widespread. The recommendations given with the consensus process might be a useful tool in the hands of surgeons. © 2012 The Authors.

    Full Text Available A 31-year-old nulligravid underwent laparoscopic myomectomy and the masses were removed by an electric morcellator. Five years later, this patient suffered from acute pelvic pain and received an operation. During laparoscopic surgery, an 8-cm right-sided multiloculated ovarian cyst with chocolate-like content was seen. After adhesiolysis, two parasitic myomas (each ∼2 cm in diameter were found attached to the right ovarian cyst and the other two parasitic myomas (each ∼1 cm in diameter were found at the right infundibulopelvic ligament and omentum respectively. These tumors were successfully removed by laparoscopic procedure. Histopathological examination confirmed that all masses were leiomyomas and the right ovarian cyst was confirmed to be endometriosis. The formation of parasitic myomas was assumed that myomatous fragments during morcellation at the time of myomectomy may have been left behind unintentionally. Thus, morcellator should be used carefully. With that being said, all of the myomatous fragment should be removed after morcellation.

    Objective: To determine the medium and long-term outcome of orthotopic continent urinary diversion with ileal (Studer) neo-bladder following radical cystectomy. Study Design: Case series. Place and Duration of Study: Department of Surgery, The Aga Khan University Hospital, Karachi, from January 1998 to September 2010. Methodology: Thirty eight patients underwent radical cystectomy for invasive bladder tumor with ileal neo-bladder (Studer type) reconstruction. Peri-operative and late complications, functional outcome of neo-bladder, urinary continence, metabolic and upper urinary tract status and overall survival were evaluated in all patients. Results: A total of 29 patients (23 males and 6 females) with mean age of 59 +- 12 years were included for the final analysis. The mean duration of surgery (both radical cystectomy and urinary diversion) was 520 +- 70 minutes. Perioperative complication rate was 24% (n=7) with surgical site infection in 4 patients, sepsis in 1 patient and 2 had ureteroileal leak. At 6 months follow-up, 22 patients were fully continent while 7 patients had minimal stress / nocturnal incontinence. The continence rate was 93% (n=27) at one year follow-up. The mean capacity of neo-bladder at 6 months was 384 +- 66 mLs. The late complication rate was 17% (n=5). Three patients developed anastomotic stricture requiring transurethral incision of neo bladder neck, one formed stone in neo-bladder and one developed incision hernia. All patients had preserved renal functions on follow-up. The survival rate was 80% (n=23) at a median follow-up of 66.4 +- 36 months. Two patients developed local recurrence and four developed distant metastasis. Conclusion: Studer ileal neo-bladder is a safe and effective option for urinary diversion in select patients with good oncological and functional outcomes comparable to contemporary literature, even in a low volume center.

    Urinary tract infection (UTI) is one of the most common complications after radical cystectomy and orthotopic neobladder reconstruction. This study investigated the incidence and implicated pathogen of febrile UTI after ileal neobladder reconstruction and identify clinical and urodynamic parameters associated with febrile UTI. From January 2001 to May 2015, 236 patients who underwent radical cystectomy and ileal neobladder were included in this study. Fifty-five episodes of febrile UTI were identified in 46 patients (19.4%). The probability of febrile UTI was 17.6% and 19.8% at 6 months and 24 months after surgery, respectively. While, Escherichia coli was the most common implicated pathogen (22/55, 40.0%), Enterococcus spp. were the most common pathogen during the first month after surgery (18/33, 54.5%). In multivariate logistic regression analysis, ureteral stricture was an independent risk factor associated with febrile UTI (OR 5.93, P = 0.023). However, ureteral stricture accounted for only 6 episodes (10.9%, 6/55) of febrile UTI. Most episodes of febrile UTI occurred within 6 months after surgery. Thus, to identify risk factors associated with febrile UTI in the initial postoperative period, we assessed videourodynamics within 6 months after surgery in 38 patients. On videourodyamic examination, vesicoureteral reflux (VUR) was identified in 16 patients (42.1%). The rate of VUR presence in patients who had febrile UTI was not significantly different from those in patients without febrile UTI (50% vs. 39.3%, P = 0.556). Patients with febrile UTI had significantly larger residual urine volume (212.0 ± 193.7 vs. 90.5 ± 148.2, P = 0.048) than those without. E. coli and Enterococcus spp. are common pathogens and ureteral stricture and residual urine are risk factors for UTI after ileal neobladder reconstruction.

    Appendicovesicostomy is commonly employed to facilitate drainage of urine through the catheter. Due to the tendency to less invasive procedures for the treatment of patients with neurogenic bladder, laparoscopy has been used as an alternative to open surgery, with the immediate advantages of postoperative recovery, shorter postoperative ileus, better cosmetic results, lower postoperative pain and early reintegration into everyday life. Compare the results of laparoscopic procedure with open appendicovesicostomy. We conducted an observational, analytical, longitudinal, ambispective cohort study, which included patients from 6-16 years of age diagnosed with neurogenic bladder, operated through laparoscopic and open appendicovesicostomy from January 2009 to June 2013. Information was obtained from clinical records. Six patients were operated laparoscopically and 14 by open approach. Surgical time was longer and statistically significant in the laparoscopic group with a median of 330 min (300-360 min) compared to open procedure of 255 min (180-360 min). Seven patients had complications in the open group and only one in the laparoscopic group. The difference in the dose of analgesics and time of use was statistically significant in favor of the laparoscopic group. The degree of urinary continence through the stoma was higher for laparoscopic (100%) compared to the open procedure (64%). In neurogenic bladder with urodynamic bladder capacity and leak point pressure bladder within acceptable values, laparoscopic appendicovesicostomy was a better alternative.

    An experiment was conducted to estimate the true ileal digestibility of P in wheat, sorghum, soybean meal, and corn distiller's dried grains with solubles (DDGS) in broiler chickens. Four semipurified diets were formulated from each ingredient (wheat and sorghum: 236.5, 473, 709.5, and 946 g/kg; soybean meal and corn DDGS: 135, 270, 405, and 540 g/kg) to contain graded concentrations of nonphytate P. The experiment was conducted as a randomized complete block design with 4 weight blocks of 16 cages each (5 birds per cage). A total of 320 21-d-old broilers (Ross 308) were assigned to the 16 test diets with 4 replicates per diet. Apparent ileal digestibility coefficients of P were determined by the indicator method and the linear regression method was used to determine the true P digestibility coefficients. The results showed that the apparent ileal P digestibility coefficients of wheat-based diets were not influenced (P>0.05) by increasing dietary P concentrations, whereas those of diets based on sorghum, soybean meal, and corn DDGS differed (Pdigestibility in broilers fed diets with soybean meal and corn DDGS linearly (Pdigestibility coefficients of wheat, sorghum, soybean meal, and corn DDGS were determined to be 0.464, 0.331, 0.798, and 0.727, respectively. Ileal endogenous P losses in birds fed diets with wheat, soybean meal, and corn DDGS were estimated to be 0.080, 0.609, and 0.418 g/kg DMI, respectively. In birds fed sorghum-based diets, endogenous P losses were estimated to be negative (-0.087 g/kg DMI). True digestible P contents of wheat, sorghum, soybean meal, and corn DDGS were determined to be 1.49, 0.78, 5.16, and 5.94 g/kg, respectively. The corresponding nonphytate P contents in wheat, sorghum, soybean meal, and corn DDGS were 1.11, 0.55, 2.15, and 4.36 g/kg, respectively. These differences between digestible P and nonphytate P contents may be suggestive, at least in part, of overestimation of P digestibility under the calcium-deficient conditions

    Full Text Available Duplications of the alimentary tract are infrequent anomalies. They are most frequently located in the terminal ileum, and majority of them became symptomatic before the age of 2. Presenting symptoms may include abdominal mass, intestinal obstruction, intussusception, rectal bleeding, and abdominal pain. Preoperative diagnosis is usually difficult, intra-abdominal duplications are usually diagnosed during surgical explorations of above complications. We presented a 12-year-old girl with asymptomatic ileal duplication cyst associated with non-complicated acute appendicitis, whose imaging studies at admission were compatible with complicated perforated appendicitis.

    Fetal intestinal volvulus is a rare life-threatening condition usually manifesting after birth with most cases being associated with intestinal malrotation. It appears on prenatal sonography (US) as a twisting of the bowel loops around the mesenteric artery, leading to mechanical obstruction and ischemic necrosis of the bowel. We report a case of intrauterine intestinal volvulus with ileal atresia, suspected when US revealed a typical "whirlpool" sign at 37 weeks' gestation, with a segment of markedly distended bowel loops and small amount of fetal ascites.

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

    A small number of patients fail fundoplication and require reoperation. Laparoscopic techniques have been applied to reoperative fundoplications. We reviewed our experience with reoperative laparoscopic fundoplication. Reoperative laparoscopic fundoplication was undertaken in 28 patients, 19 F and 9 M, of mean age 56 years +/- 12. Previous antireflux procedures included 19 open and 12 laparoscopic antireflux operations. Symptoms were heartburn (90%), dysphagia (35%), and atypical symptoms (30%%). The mean interval from antireflux procedure to revision was 13 months +/- 4.2. The mean DeMeester score was 78+/-32 (normal 14.7). Eighteen patients (64%) had hiatal breakdown, 17 (60%) had wrap failure, 2 (7%) had slipped Nissen, 3 (11%) had paraesophageal hernias, and 1 (3%) had an excessively tight wrap. Twenty-five revisions were completed laparoscopically, while 3 patients required conversion to the open technique. Complications occurred in 9 of 17 (53%) patients failing previous open fundoplications and in 4 of 12 patients (33%) failing previous laparoscopic fundoplications and included 15 gastrotomies and 1 esophagotomy, all repaired laparoscopically, 3 postoperative gastric leaks, and 4 pneumothoraces requiring tube thoracostomy. No deaths occurred. Median length of stay was 5 days (range 2-90 days). At a mean follow-up of 20 months +/- 17, 2 patients (7%) have failed revision of their fundoplications, with the rest of the patients being essentially asymptomatic (93%). The results achieved with reoperative laparoscopic fundoplication are similar to those of primary laparoscopic fundoplications. Laparoscopic reoperations, particularly of primary open fundoplication, can be technically challenging and fraught with complications. Copyright 2001 Academic Press.

    2014-03-01

    Identifying the set of skills that can transfer from laparoscopic to robotic surgery is an important consideration in designing optimal training curricula. We tested the degree to which laparoscopic skills transfer to a robotic platform. Fourteen medical students and 14 surgery residents with no previous robotic but varying degrees of laparoscopic experience were studied. Three fundamentals of laparoscopic surgery tasks were used on the laparoscopic box trainer and then the da Vinci robot: peg transfer (PT), circle cutting (CC), and intracorporeal suturing (IS). A questionnaire was administered for assessing subjects' comfort level with each task. Standard fundamentals of laparoscopic surgery scoring metric were used and higher scores indicate a superior performance. For the group, PT and CC scores were similar between robotic and laparoscopic modalities (90 versus 90 and 52 versus 47; P > 0.05). However, for the advanced IS task, robotic-IS scores were significantly higher than laparoscopic-IS (80 versus 53; P robotic-PT score when compared with laparoscopic-PT (92 versus 105; P  0.05). The robot was favored over laparoscopy for all drills (PT, 66.7%; CC, 88.9%; IS, 94.4%). For simple tasks, participants with preexisting skills perform worse with the robot. However, with increasing task difficulty, robotic performance is equal or better than laparoscopy. Laparoscopic skills appear to readily transfer to a robotic platform, and difficult tasks such as IS are actually enhanced, even in subjects naive to the technology. Copyright © 2014 Elsevier Inc.

    Full Text Available The ideal treatment for choledocholithiasis should be simple, readily available, reliable, minimally invasive and cost-effective for patients. We performed this study to compare the benefits and drawbacks of different laparoscopic approaches (transcystic and choledochotomy for removal of common bile duct stones.A systematic search was implemented for relevant literature using Cochrane, PubMed, Ovid Medline, EMBASE and Wanfang databases. Both the fixed-effects and random-effects models were used to calculate the odds ratio (OR or the mean difference (MD with 95% confidence interval (CI for this study.The meta-analysis included 18 trials involving 2,782 patients.

    After establishing a method for ileal mucosa transplantation in an animal model, the authors investigated the absorptive capacity for oligopeptides of the transplanted mucosa. In 14 beagle dogs the authors transplanted ileal mucosa in a vascularized demucosed segment of the transverse colon. The colonic wall-ileal mucosa complex then was integrated in the ileal continuity. Six animals were lost owing to operative complications. Absorptive capacity for oligopeptides was measured in the remaining 8 animals with the iodine 131 (131I)-marked tripeptide glycine-tyrosine-glycine before and 4 weeks after transplantation. The results were compared and analyzed with the Student's t test for matched pairs. Blood concentrations of the marked tripeptide with P value less than .05 were considered as a significant reduction in the absorptive capacity of the transplanted ileal mucosa. After fixation with glutaraldehyd graft, uptake of the colonic wall-ileal mucosa complex was evaluated histologically in 8 animals. In all 8 animals, a 100% graft uptake was verified in all sections. Fifteen minutes after application of 15 MBc Glycine-131I-Tyrosine-Glycine there was no significant difference in the absorption between normal and transplanted ileal mucosa. After 30 minutes, the absorption of the transplanted ileal mucosa showed a tendency (P < .1) for an impaired uptake of the marked tripeptide. However, 60 minutes after application the difference in the absorptive capacity of the transplanted ileal mucosa was significant (P < .05). Autologous allotopic ileal mucosa transplantation is feasible; however, an impaired absorption of oligopeptides of the transplanted mucosa 4 weeks after transplantation could be observed.

    Leutriene (LTC4) is one of the components of Slow Reacting Substance of Anaphylaxis (SRS-A) and is a potent constrictor of guinea pig ilea. The contraction is likely to be a receptor-mediated process. Here the authors report the existence of specific binding sites for 3 H-LTC4 in a crude membrane preparation from guinea pig ileal longitudinal muscle. At 4 degrees C in the presence of 20 mM Serine-borate, binding increases linearly with protein concentration, reaches equilibrium in 10 minutes, and is reversible upon addition of 3 x 10(-5) M unlabelled LTC4. The dissociation curve is consistent with the existence of more than one class of binding site. Ca++ and Mg++ greatly enhance the binding of 3 H-LTC4 at equilibrium. In the presence of 5 mM CaCl 2 and MgCl 2 not only LTC4 (IC50 10(-7)M), but also LTD4 and the SRS-A antagonist FPL 55712 can compete with 3 H-LTC4 for its binding sites. FPL 55712 only displaces 60-70% of the total amount bound, while LTC4 displaces 90-95%. These studies indicate that multiple classes of binding sites exist for 3 H-LTC4 in guinea pig ileal longitudinal muscle, and that at least part of these binding sites might be related to the ability of LTC4 to contract guinea pig ilea

    Full Text Available Urinary diversion reconstruction is essential after radical cystectomy and neobladder reconstruction is accepted as a fine option. This study included 51 patients, who underwent radical cystectomy with orthotopic neobladder reconstruction by a Hautmann ileal neobladder with chimney modification from 2006 to 2014. Functional outcomes were evaluated using a questionnaire and uroflowmetry. Perioperative complications were analyzed retrospectively. The mean follow-up period was 36.1 months. Eighty-six percent of patients voided without clean intermittent catheterization (CIC assistance. CIC was used 1-2x per day or every time they voided in 8% and 6% of patients, respectively, and 71% of patients were continent. The percentages of patients who used 1, 2, 3-4, and ≥5 pads per day were 15%, 6%, 2%, and 6%, respectively. Daytime and nighttime continence were achieved in 86% and 69% of patients, respectively. Daily mucus leakage was reported in 69% of patients. The mean maximum neobladder capacity, voided volume, postvoid residual volume, and maximum flow rate were 413.2 mL, 370.6 mL, 43.7 mL, and 20.8 mL/s, respectively. Eighteen early and 5 late complications developed in 13 and 5 patients, respectively. Reoperations were needed in 7 patients. The Hautmann ileal neobladder with chimney modification provided satisfactory results regarding functional outcomes.

    Full Text Available The aim of the current study was to determine the effect of extrusion process on apparent metabolizable energy (AME, crude protein (CP and amino acid (AA digestibility of canola meal (CM in broiler chickens. A total of 36, 42-day-old broilers were randomly assigned into adaptation diets (no CM or 30% CM with six replicates. After 4 days of adaptation period, on day 47, birds were allowed to consume the assay diets that contain CM or extruded canola meal (ECM as the sole source of energy and protein. Following 4 h after feeding, the birds were killed and ileal contents were collected. The results showed that ECM had greater (P<0.001 AME (10.87 vs 9.39 MJ/kg compared to CM. The extrusion also significantly enhanced apparent ileal digestibility of CP and some of AA such as Asp, Glu, Ser, Thr and Trp. In conclusion, the extrusion treatment appeared to be a practical and effective approach in enhancing the digestibility of AME, CP and some AA of CM in broiler chickens.

    Full Text Available Familial hypercholesterolemia is characterized by high serum levels of total cholesterol and LDL-cholesterol. It may be homozygous or heterozygous. In homozygous patients, LDL-cholesterol levels range from 500 to 1000mg/dL and coronary artery disease is precocious, usually manifesting itself between the 2nd and 3rd decades of life. The diagnosis is often made by the presence of xanthoma tuberosum and tendinous xanthomas that appear between the 1st and 2nd decades of life. The use of high doses of statins or even unusual procedures (apheresis, partial ileal bypass surgery, liver transplantation, gene therapy, or both, is necessary for increasing survival and improving quality of life, because a reduction in cholesterol levels is essential for stabilizing the coronary artery disease and reducing xanthomas. We report our experience with 3 patients with xanthomatous familial hypercholesterolemia and coronary artery disease, who underwent partial ileal bypass surgery. Their follow-up over the years (approximately 8 years showed a mean 30% reduction in total cholesterol, with a significant reduction in the xanthomas and stabilization of the coronary artery disease.

    Full Text Available An experiment was conducted to evaluate the effect of dietary Orgacids® (organic acid; OA supplementation on the productive performance, nutrients ileal digestibility, relative weight of organs and serum enzyme activities in broiler chickens. One hundred-sixty Ross 308 male chicks were randomly allotted to 4 dietary treatments: a nutritionally balanced basal diet supplemented with 0, 1, 2 and 3 OA g kg–1 of feed from 7 to 42 d of age. Each treatment had 4 replications with 10 broilers/replicate pen. As a result of this study, body weight, average daily gain and average daily feed intake increased (linear effect, P<0.05 at 3 g kg–1 of OA inclusion, whereas feed conversion ratio was negatively affected by dietary treatments (quadratic, P<0.05 as inclusion of OA increased to 2 g kg-1 and then decreased with further inclusion. Ileal digestibility of total phosphorus and relative weight of pancreas, heart and spleen increased (linear effect, P<0.05 with increasing inclusion of OA. Metabolizable energy corrected to zero nitrogen retention increased linearly and quadratically on increasing OA addition reaching a maximum at 2 g kg–1 diet. The results indicated that serum enzyme activity of alkaline phosphatase and alanine aminotransferase increased (linear effect, P<0.05 with increasing inclusion levels of OA, but lactate dehydrogenase decreased. In conclusion, these findings demonstrate that the OA supplementation at 3 g kg–1 of the diet resulted in optimal growth performance and nutrients digestibility.

    The objective of the experiment reported here was to investigate and compare the amino acid (AA) digestibility of distillers' dried grains (DDG), distillers' dried grains with solubles (DDGS), high protein distillers' dried grains (HP-DDG), and high protein distillers' dried grains with solubles (HP-DDGS) in growing pigs. Five semi-purified diets consisting of DDG, DDGS, HP-DDG, HP-DDGS, and nitrogen-free diet (NFD) were fed to pigs fitted with simple T-cannula for 5 observations per diet. Endogenous losses of AA at the terminal ileum of pigs that received the NFD were used to calculate standardized ileal digestibility (SID) of AA from apparent ileal digestibility (AID) of AA. The AID of Lys in DDGS was lower ( P  digestibility, there was no difference between DDG and DDGS in the SID of the indispensable AA. The SID of Lys in DDG was greater ( P  digestibility values for traditional and high-protein corn distillers' dried grains coproducts for use in formulating swine diets. Amino acid digestibility was generally higher in HP-DDG than in other tested co-products of the dry grind processing of corn for ethanol.

    Full Text Available Primary repair of traumatic colonic perforation is progressively gaining acceptance as the best method of management. However, when delayed, the risk of infection-related complications may increase. Here, we present a new method of repairing colon perforation in the presence of peritonitis. Acute colon injury was simulated in 22 German shepherd dogs. The dogs were randomly divided into two groups of 11 and after 24 hours they were operated on. The perforations were repaired by subserosal suture technique. In the first group (group A, ileal patch was used. In the other group (group B, the colon was closed by debridement and anastomosis. After 6 weeks, the repairs were assessed on the basis of survival, gross and histological assessments. Nine (82% dogs in group A and six (56% in group B survived. Ileal patch utilization significantly decreased the mortality rate (p < 0.05. The cause of death in two group A dogs and five group B dogs was peritonitis and intra-abdominal abscess formation. None of the surviving dogs showed evidence of anastomotic leakage or breakdown. Small bowel patch used in primary repair of colon injury in the presence of peritonitis may decrease the risk of postoperative infection-related complications and the mortality rate.

    Interactions between the host and gut microbial community likely contribute to Crohn disease (CD) pathogenesis; however, direct evidence for these interactions at the onset of disease is lacking. Here, we characterized the global pattern of ileal gene expression and the ileal microbial community in 359 treatment-naive pediatric patients with CD, patients with ulcerative colitis (UC), and control individuals. We identified core gene expression profiles and microbial communities in the affected CD ilea that are preserved in the unaffected ilea of patients with colon-only CD but not present in those with UC or control individuals; therefore, this signature is specific to CD and independent of clinical inflammation. An abnormal increase of antimicrobial dual oxidase (DUOX2) expression was detected in association with an expansion of Proteobacteria in both UC and CD, while expression of lipoprotein APOA1 gene was downregulated and associated with CD-specific alterations in Firmicutes. The increased DUOX2 and decreased APOA1 gene expression signature favored oxidative stress and Th1 polarization and was maximally altered in patients with more severe mucosal injury. A regression model that included APOA1 gene expression and microbial abundance more accurately predicted month 6 steroid-free remission than a model using clinical factors alone. These CD-specific host and microbe profiles identify the ileum as the primary inductive site for all forms of CD and may direct prognostic and therapeutic approaches.

    2014-01-01

    Full Text Available Introduction. Restorative surgery for ulcerative colitis with ileal pouch anal anastomosis (IPAA is frequently accompanied by complications. Volvulus of the ileal pouch is one of the most rarely reported late complications and to our knowledge no report exists on reoperative surgery for this condition. Case Report. A 58-year-old woman who previously had undergone restorative proctocolectomy due to ulcerative colitis with an IPAA presented with volvulus of the pouch. She was operated with a single row pouchopexy to the presacral fascia. Two months later she returned with a recurrent volvulus. At reoperation, the pouch was found to have become completely detached from the fascia. A new pexy was made by firmly anchoring the pouch with two rows of sutures to the presacral fascia as well as with sutures to the lateral pelvic walls. At follow-up after five months she was free of symptoms. Conclusion. This first report ever on reoperative surgery for volvulus of a pelvic pouch indicates that a single row pouchopexy might be insufficient for preventing retwisting. Several rows seem to be needed.

    Full Text Available Background: Ulcerative colitis patients who underwent restorative proctocolectomy with ileal pouch-anal anastomosis can develop various mechanical complications. Among them is presacral sinus resulting from chronic anastomotic leak. Methods: We present a symptomatic patient with a large fecalith blocking the sinus which was successfully treated with Doppler ultrasound guided endoscopic needle knife sinusotomy along with fecalith extraction. Results: A 67-year-old female presented with a 4-month history of perianal pain and urgency. Pouchocopy showed a 3-cm deep wide-mouthed anastomotic sinus, the orifice of which was blocked by a large hard fecalith. Removal of the fecalith using RothNet, Tripod, or Basket were made but failed. Then needle knife was applied to cut the orifice to enlarge the opening of the sinus. One month later, the patient returned and the fecalith was successfully removed with two Baskets and two Rothnets. Six months after fecalith extraction, pouchoscopy showed a compartalized distal pouch sinus with two cavities, which was treated by two sessions of Doppler ultrasound guided endoscopic needle knife sinusotomy. Six months following the treatment, the sinus was completed healed. The patient tolerated all procedures well without any complication. Conclusion: Fecalith blocking pouch anastomotic sinus is a rare complication in patients with restorative proctocolectomy. In our case, this surgical complication was successfully treated with a carefully planned, stepwise endoscopy approach. Resumo: Experiência: Pacientes com colite ulcerativa tratados por proctocolectomia restauradora com anastomose bolsa ileal-anal podem ser acometidos por diversas complicações mecânicas.

    Full Text Available Gallbladder stones are an endemic disease of hepatobiliary system.Whereas, cholecystoenteric fistules which develop by depending on gallbladder stone are rarely seen complications. A diagnosis is usually established during an operation. As is seen in our case too, in view of acute-stoned cholecystitis, laparoscopy has been carried out and a diagnosis of cholecystoduodenal fistule has been established during laparoscopy. Our case to whom laparoscopic duodenography and cholecystectomy has been applied is a rarely seen disease in literature. So, we aimed at sharing this information.

    Full Text Available "Peritonitis fibrosa incapsulata", first described in 1907, is a condition characterized by encasement of the bowel with a thick fibrous membrane. This condition was renamed as "abdominal cocoon" in 1978. It presents as small bowel obstruction clinically. 35 cases of abdominal cocoon have been reported in the literature over the last three decades. Abdominal cocoon is more common in adolescent girls from tropical countries. Various etiologies have been described, including tubercular. It is treated surgically by releasing the entrapped bowel. We report a laparoscopic experience of tubercular abdominal cocoon and review the literature.

    This prospective study describes a simple method of combining laparoscopic ovariectomy and laparoscopic-assisted prophylactic gastropexy and determines the duration of surgery, complications, and long-term outcome including prevention of gastric dilatation-volvulus (GDV). Laparoscopic ovariectomy and laparoscopic-assisted gastropexy were performed on 26 sexually intact female dogs susceptible to GDV. The mean surgery time was 60.8 ± 12.4 min. No GDV episode was seen during the study period (mean follow-up: 5.2 ± 1.4 y). All dogs had an intact gastropexy attachment assessed by ultrasonography at 1 y. Post-operative complications were minor and owners were satisfied with the procedure. Combined laparoscopic ovariectomy and laparoscopic- assisted gastropexy appears to be a successful and low morbidity alternative procedure to both ovariectomy/ovariohysterectomy and gastropexy via open ventral-midline laparotomy.

    Full Text Available Abstract Background Interposition of a reversed jejunal loop in short bowel sydrome has previously been investigated in human along with animal models and seemed able to facilitate intestinal adaptation. However, it is unclear if growth hormone and insulin, well known for their implication in short bowel pathophysiology, intervene on this effect. Findings Porcine models were randomly allocated to two cohorts: (1 short bowel (SB group (n = 8 and (2 short bowel reverse jejunal segment (SB-RS group (n = 8. Amongst other parameters serum growth hormone and insulin were measured at baseline, as well as on postoperative day 30 and 60. Conclusion Both endogenous hormones failed to demonstrate significant difference in respect to potential direct effect to mechanisms of enhanced intestinal adaptation in reversed group

    Full Text Available This study aimed to evaluated laparoscopic ureterocalicostomy as treatment of experimental ureteropelvic junction (UPJ obstruction in pigs. Ten male Large White pigs weighting approximately 28.4 (±1.43 kg were used in the current study. The UPJ obstruction was created laparoscopically by double-clipping of the left ureter. After 14 days the animals underwent laparoscopic ureterocalicostomy f The animals were sacrificed for subsequent retrograde pyelography in order to assess the anastomotic patency on the 28th day. The laparoscopic procedure for experimental obstruction of UPJ was successfully performed in all animals, as well as the laparoscopic ureterocalicostomy. There was intestinal iatrogenic injury in one animal. Satisfactory UPJ patency was noted in 75% of the animals. There was no stenosis of the proximal anastomosis between the ureter and the lower pole of the kidney in 37.5%, mild stenosis in 37.5% and severe stenosis in 25% of the animals. The laparoscopic approach for reestablishment he urinary flow by ureterocalicostomy was feasible in the porcine model. The ascending pyelography revealed satisfactory results of the laparoscopic ureterocalicostomy

    Full Text Available Introduction: Laparoscopic cholecystectomy has clearly become the choice over open cholecystectomy in the treatment of hepatobiliary disease since its introduction by Mouret in 1987. This study evaluates a series of patients with chronic calculus cholecystitis who were treated with laparoscopic and open cholecystectomy and assesses the outcomes of both techniques. Objective: To evaluate the efficacy of laparoscopic vs open cholecystectomy in chronic calculus cholecystitis and establish the out-comes of this treatment modality at Lumbini Medical College and Teaching Hospital. Methods: This was a retrospective analysis over a one-year period (January 1, 2012 to December 31, 2012, per-formed by single surgeon at Lumbini Medical College and Teaching Hospital located midwest of Nepal. 166 patients underwent surgical treatment for chronic calculus cholecystitis. Patients included were only chronic calculus cholecystitis proven histopathologocally and the rest were excluded. Data was collected which included patients demographics, medical history, presentation, complications, conversion rates from laparoscopic. cholecystectomy to open cholecystectomy, operative and postoperative time. Results: Patients treated with laparoscopic cholecystectomy for chronic calculus cholecystitis had shorter operating times and length of stay compared to patients treated with open cholecystectomy for chronic calculus cholecystitis. Conversion rates were 3.54% in chronic calculus cholecystitis during the study period. Complications were also lower in patients who underwent laparoscopic cholecystectomy versus open cholecystectomy for cholelithiasis. Conclusions: Laparoscopic cholecystectomy appears to be a reliable, safe, and cost-effective treatment modality for chronic calculus cholecystitis.

    2008-01-01

    In recent years the progress of laparoscopic procedures and the development of new and dedicated technologies have made laparoscopic hepatic surgery feasible and safe. In spite of this laparoscopic liver resection remains a surgical procedure of great challenge because of the risk of massive bleeding during liver transection and the complicated biliary and vascular anatomy in the liver. A new laparoscopic device is reported here to assist liver resection laparoscopically. The laparoscopic Habib 4X is a bipolar radiofrequency device consisting of a 2 x 2 array of needles arranged in a rectangle. It is introduced perpendicularly into the liver, along the intended transection line. It produces coagulative necrosis of the liver parenchyma sealing biliary radicals and blood vessels and enables bloodless transection of the liver parenchyma. Twenty-four Laparoscopic liver resections were performed with LH4X out of a total of 28 attempted resections over 12 months. Pringle manoeuvre was not used in any of the patients. None of the patients required intraoperative transfusion of red cells or blood products. Laparoscopic liver resection can be safely performed with laparoscopic Habib 4X with a significantly low risk of intraoperative bleeding or postoperative complications.

    Perineal hernias are infrequent complications following abdominoperineal operations. Various approaches have been described for repair of perineal hernias including open transabdominal, transperineal or combined abdominoperineal repairs. The use of laparoscopic transabdominal repair of perineal hernias is not well-described. We present a case report demonstrating the benefits of laparoscopic repair of perineal hernia following previous laparoscopic abdominoperineal resection (APR) using a nonabsorbable mesh to repair the defect. We have demonstrated that the use of laparoscopy with repair of the pelvic floor defect using a non absorbable synthetic mesh offers an excellent alternative with many potential advantages over open transabdominal and transperineal repairs.

    Full Text Available Central pancreatectomy is an ideal surgical procedure for the treatment of benign or low-grade malignant tumors in the pancreatic neck or the proximal body of the pancreas, and it can preserve more normal pancreatic tissue in order to reduce the incidence of endocrine and exocrine insufficiency after surgery. Although some clinical studies have demonstrated the feasibility and safety of this procedure, laparoscopic central pancreatectomy was technically challenging with a few number of cases. This article reviews the current status of laparoscopic central pancreatectomy and introduces our clinical experience of laparoscopic central pancreatectomy and pancreaticojejunostomy.

    Placement of feeding tubes is a common procedure for general surgeons. While the advent of percutaneous endoscopic gastrostomy has changed and improved surgical practice, this technique is contraindicated in many circumstances. In some patients placement of feeding tubes in the stomach may be contraindicated due to the risks of aspiration, gastric paresis, or gastric dysmotility. We describe a technique of laparoscopic jejunostomy tube placement which is easy and effective. It is noteworthy that this method may be used in patients who have had previous abdominal operations, and it has the added advantage of a direct peritoneal view of the viscera. We suggest that qualified laparoscopic surgeons learn the technique of laparoscopic jejunostomy.

    1992-04-01

    With the advent and rapid proliferation of laparoscopic cholecystectomy, numerous techniques and "tips" have been described. Intraoperative cholangiography during laparoscopic cholecystectomy can be tedious, frustrating, and time consuming. Described herein is a technique of intraoperative cholangiography during laparoscopic cholecystectomy which has proven to be easy, fast, and succinct. This method utilizes a rigid cholangiogram catheter which is placed into the peritoneal cavity through a small additional puncture site. This catheter is easily inserted into the cystic duct by extracorporeal manipulation. We suggest this method to surgeons who have shared our prior frustration with intraoperative cholangiography.

    Full Text Available Port site wound infection, abdominal wall hematoma and intraabdominal abscess formation has been reported after laparoscopic appendicectomy. We describe here a rectus sheath abscess which occurred three weeks after the laparoscopic appendicectomy. It was most likely the result of secondary infection of the rectus sheath hematoma due to bleeding into the rectus sheath from damage to the inferior epigastric arteries or a direct tear of the rectus muscle. As far as we are aware this complication has not been reported after laparoscopic appendicectomy.

    To evaluate the outcome of Laparoscopic Cholecystectomy in Gall stone disease, critically analyzing the complication rate, morbidity and mortality rate. All patients (>12 years) with cholelithiasis were included in this study. Patients with common bile duct dilatation (>8mm) or stones, or gall bladder mass or jaundice, and those declared unfit for anaesthesia were excluded. The detailed data of all the cases was compiled and analyzed. Out of the total of 1345 patients operated during the study period, 1234 (91.75%) were females and 111 (8.25%) males; their ages ranged from 12 to 89 years, majority were in the age bracket of 30-50 years. Our conversion rate was 6.4%. Nine (0.67%) patients developed bleeding from the port site, 30 (2.23%) port site infection, 43 (3.20%) umbilical port hernia, two bile ducty injury and one colonic injury. There was no mortality in this series. Laparoscopic Cholecystectomy is a safe and effective treatment for Cholelithiasis. (author)

    Most of amino acid (AA) digestibility values for feed ingredients are obtained using pigs cannulated in the distal ileum. The ileal-cannulated pig model uses pigs older than six weeks due to difficulties related to implanting the T-cannula in distal ileum of younger pigs and complications during the post-surgical recovery. However, to properly formulate the diet of weaned pigs, the nutritive value of feed ingredients should be determined with younger pigs. Thus, 25 weaned pigs were used to determine the apparent total tract digestibility (ATTD) of nutrients, energy, and apparent ileal digestibility (AID) and standardized ileal digestibility (SID) ileal AA digestibility of broken rice (BR), with or without multicarbohydrase (MC) and phytase (Phy) supplementation. Piglets were weaned at 23 d of age and individually housed in digestibility cages until 45 d of age. The trial consisted of 7 d of adaptation to the experimental diets and 3 d of excreta (feces and urine) collection. Ileal digesta was collected at slaughter (about 6 weeks of age). A completely randomized experimental design was used to determine the effects of MC and Phy. Reference diets (RD, 5% casein) was replaced by 30% of BR with or without MC, Phy, or MC+Phy. The RD was used to quantify endogenous AA losses. BR with Phy supplied had increased the ATTD of dry matter (pdigestible energy and protein and SID for histidine (pdigestibilities. Standardized amino acid digestibilities of BR, without enzymes, were lower than those values reported in the literature. The MC and Phy improved the digestibility of some nutrients and energy of BR in post-weaned piglet diets.

    Background: Ulcerative colitis (UC) only involves the colonic mucosa. Yet, nearly 50% of patients with UC who undergo total proctocolectomy with ileal pouch anal anastomosis develop UC-like inflammation of the ileal pouch (pouchitis). By contrast, patients with familial adenomatous polyposis (FAP) with ileal pouch anal anastomosis develop pouchitis far less frequently. We hypothesized that pathogenic events associated with the development of UC are recapitulated by colonic-metaplastic transcriptomic reprogramming of the UC pouch. Methods: We prospectively sampled pouch and prepouch ileum mucosal biopsies in patients with UC with ileal pouch anal anastomosis 4, 8, and 12 months after their pouch was in continuity. Mucosal samples were also obtained from patients with FAP. Transcriptional profiles of the UC and FAP pouch and prepouch ileum were investigated via RNA sequencing and compared with data from a previously published microarray study. Results: Unlike patients with FAP, subjects with UC exhibited a large set of differentially expressed genes between the pouch and prepouch ileum as early as 4 months after pouch functionalization. Functional pathway analysis of differentially expressed genes in the UC pouch revealed an enhanced state of immune/inflammatory response and extracellular matrix remodeling. Moreover, >70% of differentially expressed genes mapped to published inflammatory bowel diseases microarray data sets displayed directional changes consistent with active UC but not with Crohn's disease. Conclusions: The UC pouch, well before histologic inflammation, already displays a systems-level gain of colon-associated genes and loss of ileum-associated genes. Patients with UC exhibit a unique transcriptomic response to ileal pouch creation that can be observed well before disease and may in part explain their susceptibility to the development of pouchitis.

    Objective: To determine the incidence of intraoperative anesthesia-related complications of laparoscopic cholecystectomy. Results: One hundred patients with male to female ratio of 1:8.09 in the age range of 20-80 years (mean 39 years) underwent general anesthesia for laparoscopic cholecystectomy. The duration of operation in 94 laparoscopic cholecystectomy was from 20 to 80 minutes (mean 60.63 minutes). The incidence of intraoperative hypotension was 9%. Four percent of the patients developed arrhythmias. Increase in end-tidal-carbon dioxide (ETCO/sub 2/) was observed in 3% of cases. Conversion rate to open cholecystectomy was 6%. Damage to intraabdominal vessels with trocar insertion occurred in 1% of cases. Conclusion: Although laparoscopic cholecystectomy has major surgical and anesthetic advantages, there are anesthesia related complications requiring specific anesthetic interventions to improve patients outcome without compromising their safety.

    2013-01-01

    A best evidence topic in surgery was written according to a structured protocol. The question addressed was whether playing video games improves surgical performance in laparoscopic procedures. Altogether 142 papers were found using the reported search, of which seven represented the best evidence to answer the clinical question. The details of the papers were tabulated including relevant outcomes and study weaknesses. We conclude that medical students and experienced laparoscopic surgeons with ongoing video game experience have superior laparoscopic skills for simulated tasks in terms of time to completion, improved efficiency and fewer errors when compared to non-gaming counterparts. There is some evidence that this may be due to better psycho-motor skills in gamers, however further research would be useful to demonstrate whether there is a direct transfer of skills from laparoscopic simulators to the operating table.

    The treatment of hepatocellular carcinoma (HCC) is complicated and challenging because of the frequent presence of cirrhosis. Therefore, we propose a novel surgical approach to minimize the invasiveness and risk in patients with HCC, hypersplenism, and esophagogastric varices. This was a retrospective study carried out in 25 patients with HCC and hypersplenism and who underwent simultaneous laparoscopic-guided radio-frequency ablation and laparoscopic splenectomy with endoscopic variceal ligation. Tumor size was restricted to a single nodule of splenectomy. Laparoscopic-guided radio-frequency ablation with laparoscopic splenectomy and endoscopic variceal ligation could be an available technique for patients with HCC <3 cm, hypersplenism, and esophagogastric varices. This approach may help to minimize the surgical risks and results in a fast increase in platelet counts with an acceptable rate of complications.

    No criteria define indications for laparoscopic splenectomy in trauma. This investigation compared characteristics of trauma patients and outcomes between laparoscopic and open splenectomies. Patients were identified retrospectively by using ICD-9 codes. Included patients were 18 or older, with a blunt splenic injury from January 1, 2011, through December 31, 2014, and required splenectomy. Excluded patients had penetrating trauma, successful nonoperative management, or successful embolization. Variables included demographics, presenting characteristics, injury severity scores, abdominal abbreviated injury scores, splenic injury grade, surgical indication and approach (open or laparoscopic), surgery length, intra-operative blood loss, transfusions, length of stay, complications, mortality, and discharge disposition. Forty-one patients underwent open splenectomy, and 11 underwent laparoscopic splenectomy. The mean age was 48.7 years, and men comprised the sample majority (36/52). The groups were well matched for age, abdominal injury scores, and admission vital signs. The open group had a significantly lower level of consciousness and more acidosis compared with the laparoscopic group. Most laparoscopic splenectomies were performed after failed nonoperative management or embolization. The indications for open splenectomy were a positive focused assessment with sonography for trauma and computed tomography results. Laparoscopic patients had significantly longer times between presentation and surgery and longer operations, but had significantly less blood loss and fewer transfusions compared with the open group. There were no differences in mortality, length of stay, complications, or discharge dispositions. Laparoscopic splenectomy is useful in patients with blunt trauma in whom conservative management produced no improvement and who do not have other injuries to preclude laparoscopy.

    2014-01-01

    Background To compare the nutritional value and digestibility of five quality protein maize (QPM) hybrids to that of white and yellow maize, two experiments were carried out in growing pigs. In experiment 1, the energy metabolizability and the nitrogen balance of growing pigs fed one of five QPM hybrid diets were compared against those of pigs fed white or yellow maize. In experiment 2, the apparent and standardized ileal digestibility (AID and SID, respectively) of proteins and amino acids from the five QPM hybrids were compared against those obtained from pigs fed white and yellow maize. In both experiments, the comparisons were conducted using contrasts. Results The dry matter and nitrogen intakes were higher in the pigs fed the QPM hybrids (P digestibility (P digestible lysine than normal maize. PMID:25045520

    Laparoscopic cholecystectomy, a minimal access surgery, is fast replacing open cholecystectomy and is being associated with less trauma. The objective of this study was to compare the proinflammatory cytokine levels in both laparoscopic cholecystectomy and open cholecystectomy. This study was carried out at Aseer Central Hospital, Aseer region, Abha Private Hospital and the College of Medicine and Medical Sciences, King Khalid University, Abha, Kingdom of Saudi Arabia, during the time period October 1998 through to November 2000. Sixty-one patients were included in the study, 27 of them had laparoscopic cholecystectomy and 34 had open cholecystectomy. Cytokines [Interleukin-6 Interleukin-1b, Tumor necrosis factor -a and Interleukin- 8] were measured in blood samples collected from the patients before, at and 24 hours post surgery, using commercially available kits. Interleukin-6 levels were significantly increased at 24 hours post surgery in the open cholecystectomy group of patients compared to the laparoscopic cholecystectomy group (P<0.04). No differences were found in the other cytokines levels (Interleukin-1b, tumor necrosis factor -a and Interleukin-8) between the open cholecystectomy and laparoscopic cholecystectomy groups. Laparoscopic cholecystectomy, a minimal access surgery, is associated with lower levels of the proinflammatory interleukin-6 cytokine compared to open cholecystectomy. (author)

    Intestinal stricture, a major complication of Crohn's disease (CD), results from fibromuscular remodeling and expansion of the intestinal wall. The corresponding microanatomical alterations have not been fully described, hindering progress toward understanding their pathogenesis and devising appropriate treatments. We used tissue-specific staining and quantitative digital histomorphometry for this purpose. Serial histological sections from 37 surgically-resected ileal strictures and adjacent non-strictured controls from patients with CD were evaluated after staining for smooth muscle actin, collagen (Sirius red) and collagen types I, III and V. Overall mural thickening in strictures was increased 2.4±0.3-fold compared with non-strictured regions of the same specimens. The muscular layer most altered was the muscularis mucosae (MM). Compared with the inner and outer layers of the MP which were expanded 2.1±0.2- and 1.4±0.1-fold, respectively, the MM was expanded 22.1±3.6-fold, reflecting the combined effects of architectural disarray, an 11.6±1.4-fold increase smooth muscle content, and elaboration of pericellular type V collagen. In contrast, the architecture of the MP was preserved and pericellular collagen was virtually absent; rather, fibrosis in this layer was limited to expansion of the intramuscular septa by collagen types I and III. The muscular arteries and veins within the strictured submucosa frequently exhibited eccentric, luminally-oriented adventitial mantles comprising hyperplastic myocytes and extracellular type V collagen. We conclude that the fibromuscular remodeling which results in CD-associated ileal strictures predominantly involves the MM and submucosal vasculature in a luminally-polarized fashion and suggests that mucosal-based factors may contribute to stricture pathogenesis.

    Internal hernias have an overall incidence of less than 1% and are difficult to diagnose clinically due to their nonspecific presentation. Most internal hernias present as strangulating closed-loop obstruction and delay in surgical intervention is responsible for a high mortality rate (49%). We present a case of ileal herniation through the foramen of Winslow. A 29-year-old previously healthy female presented with acute onset right upper quadrant pain, abdominal fullness, and nausea. The pain was sudden in onset and began shortly after a dinner party where she consumed larger portions of food. Laboratory investigations revealed mild leukocytosis with left shift. Dual-phase multi-detector computed tomography disclosed herniation of the small bowel into the lesser sac. The patient underwent an emergency median laparotomy that revealed ileal herniation through the foramen of Winslow. Adhesiolysis and manual reduction of the bowel was performed, and the reduced bowel showed only congestive changes. The postoperative recovery was uneventful and the patient was discharged on the third postoperative day. Risk factors for internal herniation still remain unclear, although excessively mobile bowel loops and an enlarged foramen of Winslow have been described. Our case demonstrated that overeating could be an additional risk factor for internal herniation. We describe our clinical and radiology findings, as well as surgical management. Due to the high rates of morbidity and mortality, it is imperative that clinicians be aware of the possible risks factors for internal herniation. Internal hernias should be included in the differential diagnosis of small bowel obstruction so that appropriate steps can be made in the work-up of these patients, followed by timely surgical intervention.

    Full Text Available A vesicovaginal fistula is one of the complications that a gynaecologist is bound to face after oncological operations, especially in postmenopausal women. Over the years there have been introduced many techniques of surgical treatment of this entity, including transabdominal and transvaginal approaches.We present a case of a 46-year-old patient who suffered from urinary leakage via the vagina due to the presence of a vesicovaginal fistula that developed after radical abdominal hysterectomy and subsequent radiotherapy. The decision was made to repair it laparoscopically due to retracted, fibrous and scarred tissue in the vaginal apex that precluded a transvaginal approach. A small cystotomy followed by an excision of fistula borders was performed. After six-month follow-up no recurrence of the disease has been noted.We conclude that laparoscopy is an interesting alternative to traditional approaches that provides comparable results.

    Full Text Available INTRODUCTION : Laparoscopic splenectomy (LS is an accepted procedure for elective splenectomy. Advancement in technology has extended the possibility of LS in massive splenomegaly [Choy et al., J Laparoendosc Adv Surg Tech A 14(4, 197-200 (2004], trauma [Ren et al., Surg Endosc 15(3, 324 (2001; Mostafa et al., Surg Laparosc Endosc Percutan Tech 12(4, 283-286 (2002], and cirrhosis with portal hypertension [Hashizume et al., Hepatogastroenterology 49(45, 847-852 (2002]. In a developing country, these advanced gadgets may not be always available. We performed LS using conventional and reusable instruments in a public teaching the hospital without the use of the advanced technology. The technique of LS and the outcome in these patients is reported. MATERIALS AND METHODS : Patients undergoing LS for various hematological disorders from 1998 to 2004 were included. Electrocoagulation, clips, and intracorporeal knotting were the techniques used for tackling short-gastric vessels and splenic pedicle. Specimen was delivered through a Pfannensteil incision. RESULTS : A total of 26 patients underwent LS. Twenty-two (85% of patients had spleen size more than 500 g (average weight being 942.55 g. Mean operative time was 214 min (45-390 min. The conversion rate was 11.5% ( n = 3. Average duration of stay was 5.65 days (3-30 days. Accessory spleen was detected and successfully removed in two patients. One patient developed subphrenic abscess. There was no mortality. There was no recurrence of hematological disease. CONCLUSION : Laparoscopic splenectomy using conventional equipment and instruments is safe and effective. Advanced technology has a definite advantage but is not a deterrent to the practice of LS.

    Studies using conventional consoles have suggested a possible link between video-gaming and laparoscopic skill. The authors hypothesized that the Nintendo Wii, with its motion-sensing interface, would provide a better model for laparoscopic tasks. This study investigated the relationship between Nintendo Wii skill, prior gaming experience, and laparoscopic skill. In this study, 20 participants who had minimal experience with either laparoscopic surgery or Nintendo Wii performed three tasks on a Webcam-based laparoscopic simulator and were assessed on three games on the Wii. The participants completed a questionnaire assessing prior gaming experience. The score for each of the three Wii games correlated positively with the laparoscopic score (r = 0.78, 0.63, 0.77; P skill overlap between the Nintendo Wii and basic laparoscopic tasks. Surgical candidates with advanced Nintendo Wii ability may possess higher baseline laparoscopic ability.

    The objective of the study that is presented herein was to determine the true ileal calcium (Ca) digestibility in meat and bone meal (MBM) for broiler chickens using the direct method. Four MBM samples (coded as MBM-1, MBM-2, MBM-3 and MBM-4) were obtained and analyzed for nutrient composition, particle size distribution and bone to soft tissue ratio. The Ca concentrations of MBM-1, MBM-2, MBM-3 and MBM-4 were determined to be 71, 118, 114 and 81 g/kg, respectively. The corresponding geometric mean particle diameters and bone to soft tissue ratios were 0.866, 0.622, 0.875 and 0.781 mm, and 1:1.49, 1:0.98, 1:0.92 and 1:1.35, respectively. Five experimental diets, including four diets with similar Ca concentration (8.3 g/kg) from each MBM and a Ca and phosphorus-free diet, were developed. Meat and bone meal served as the sole source of Ca in the MBM diets. Titanium dioxide (3 g/kg) was incorporated in all diets as an indigestible marker. Each experimental diet was randomly allotted to six replicate cages (eight birds per cage) and offered from d 28 to 31 post-hatch. Apparent ileal Ca digestibility was calculated by the indicator method and corrected for ileal endogenous Ca losses to determine the true ileal Ca digestibility. Ileal endogenous Ca losses were determined to be 88 mg/kg dry matter intake. True ileal Ca digestibility coefficients of MBM-1, MBM-2, MBM-3 and MBM-4 were determined to be 0.560, 0.446, 0.517 and 0.413, respectively. True Ca digestibility of MBM-1 was higher (P 0.05) to that of MBM-3. True Ca digestibility of MBM-2 was similar (P > 0.05) to MBM-3 and MBM-4, while that of MBM-3 was higher (P digestibility in feed ingredients and that Ca in MBM is not highly available as often assumed. The variability in true Ca digestibility of MBM samples could not be attributed to Ca content, percentage bones or particle size. © 2015 Poultry Science Association Inc.

    Full Text Available O experimento foi conduzido com o objetivo de determinar a digestibilidade ileal aparente e verdadeira dos aminoácidos de seis diferentes farinhas de carne e ossos. Foram utilizados 12 suínos mestiços, machos castrados, com peso médio inicial de 52,5 ± 5,1 kg. Os animais foram previamente submetidos à cirurgia para implantação de cânula "T" simples no íleo terminal, e, após 20 dias de recuperação, foram distribuídos em um delineamento experimental de blocos ao acaso, com seis tratamentos, quatro repetições e um animal por unidade experimental. Ao término das duas primeiras repetições, os tratamentos foram redistribuídos para evitar que o mesmo animal recebesse a mesma dieta em duas repetições consecutivas. Os tratamentos consistiram de uma dieta isenta de proteína à base de açúcar, amido, óleo e casca de arroz, tendo como única fonte protéica as farinhas de carne e ossos. Os coeficientes de digestibilidade ileal aparente da lisina, treonina e metionina, das diferentes farinhas de carne e ossos variaram de 54,87 a 74,80; 62,62 a 81,19 e 72,35 a 85,46%, respectivamente, e a variação entre os coeficientes de digestibilidade ileal verdadeira foram de 57,00 a 76,08; 66,26 a 83,07 e 73,76 a 86,39%, respectivamente, para a lisina, treonina e metionina.

    To estimate readmission rates and emergency care use by patients discharged home the same day after laparoscopic hysterectomy. This was a retrospective case series of patients discharged home the same-day after total or supracervical laparoscopic hysterectomy in a managed care setting. Chart reviews were performed for outcomes of interest which included readmission rates, emergency visits, and surgical and demographic characteristics. The two hysterectomy groups were compared using χ² tests for categorical variables and t tests or Wilcoxon rank-sum tests for continuously measured variables. One-thousand fifteen laparoscopic hysterectomies were performed during the 3-year study period. Fifty-two percent (n=527) of the patients were discharged home the same-day; of those, 46% (n=240) had total laparoscopic hysterectomies and 54% (n=287) had supracervical. Cumulative readmission rates were 0.6%, 3.6%, and 4.0% at 48 hours, 3 months, and 12 months, respectively. The most common readmission diagnoses included abdominal incision infection, cuff dehiscence, and vaginal bleeding. Less than 4% of patients presented for emergency care within 48 or 72 hours, most commonly for nausea or vomiting, pain, and urinary retention. Median uterine weight was 155 g, median blood loss was 70 mL, and median surgical time was 150 minutes. There was no difference in readmission rates or emergency visits for the total compared with the supracervical laparoscopic hysterectomy group. Same-day discharge after laparoscopic hysterectomy is associated with low readmission rates and minimal emergency visits in the immediate postoperative period. Same-day discharge may be a safe option for healthy patients undergoing uncomplicated laparoscopic hysterectomy.

    Colorectal resections are common surgical procedures all over the world. Laparoscopic colorectal surgery is technically feasible in a considerable amount of patients under elective conditions. Several short-term benefits of the laparoscopic approach to colorectal resection (less pain, less morbidity, improved reconvalescence and better quality of life) have been proposed. This review compares laparoscopic and conventional colorectal resection with regards to possible benefits of the laparoscopic method in the short-term postoperative period (up to 3 months post surgery). We searched MEDLINE, EMBASE, CancerLit, and the Cochrane Central Register of Controlled Trials for the years 1991 to 2004. We also handsearched the following journals from 1991 to 2004: British Journal of Surgery, Archives of Surgery, Annals of Surgery, Surgery, World Journal of Surgery, Disease of Colon and Rectum, Surgical Endoscopy, International Journal of Colorectal Disease, Langenbeck's Archives of Surgery, Der Chirurg, Zentralblatt für Chirurgie, Aktuelle Chirurgie/Viszeralchirurgie.

The incidence of small bowel diverticulitis varies from 0.3 to 2.3 % in the general population. Complications of this rare clinical entity are often confused with other causes of acute abdomen such as acute appendicitis, perforated peptic ulcer, inflammatory bowel disease or ischemic bowel disease. Case Presentation We describe a 65-year-old male with a history of ileal diverticulosis who presented with acute abdomen and was subsequently found to have perforated ileal diverticulitis with abscess formation. Conclusions The case, differential diagnosis, imaging studies, complications and management of this rare clinical disease are discussed.

  14. Image acquisition in laparoscopic and endoscopic surgery

    1995-04-01

    Laparoscopic and endoscopic surgery rely uniquely on high quality display of acquired images, but a multitude of problems plague the researcher who attempts to reproduce such images for educational purposes. Some of these are intrinsic limitations of current laparoscopic/endoscopic visualization systems, while others are artifacts solely of the process used to acquire and reproduce such images. Whatever the genesis of these problems, a glance at current literature will reveal the extent to which endoscopy suffers from an inability to reproduce what the surgeon sees during a procedure. The major intrinsic limitation to the acquisition of high-quality still images from laparoscopic procedures lies in the inability to couple directly a camera to the laparoscope. While many systems have this capability, this is useful mostly for otolaryngologists, who do not maintain a sterile field around their scopes. For procedures in which a sterile field must be maintained, one trial method has been to use a beam splitter to send light both to the still camera and the digital video camera. This is no solution, however, since this results in low quality still images as well as a degradation of the image that the surgeon must use to operate, something no surgeon tolerates lightly. Researchers thus must currently rely on other methods for producing images from a laparoscopic procedure. Most manufacturers provide an optional slide or print maker that provides a hardcopy output from the processed composite video signal. The results achieved from such devices are marginal, to say the least. This leaves only one avenue for possible image production, the videotape record of an endoscopic or laparoscopic operation. Video frame grabbing is at least a problem to which industry has applied considerable time and effort to solving. Our own experience with computerized enhancement of videotape frames has been very promising. Computer enhancement allows the researcher to correct several of the

    Laparoscopic repair of ventral and incisional hernia has become increasingly popular as compared to open repair. The procedure has the advantages of minimal access surgery, reduction of post operative pain and the recurrence rate. A prospective study of laparoscopic incisional hernia repair was performed in our center from August 2002 to April 2004. Eighteen cases (n: 18) were performed during the study period. Fifteen cases (n: 15) had open hernia repair previously. Sixteen patients (n: 16) had successful repair of the hernia with the laparoscopic approach and two cases were converted to open repair. The mean hernia defect size was 156cm2. There was no intraoperative or immediate postoperative complication. The mean operating time was 100 +/- 34 minutes (75 - 180 minutes). The postoperative pain was graded as mild to moderate according to visual analogue score. The mean day of discharge after surgery was two days (1 - 3 days). During follow up, three patients (16.7%) developed seroma at the hernia sac which was resolved with conservative management after three weeks. One (5.6%) patient developed recurrence six months after surgery. In conclusion, laparoscopic repair of incisional hernia particularly recurrent hernia has been shown to be safe and effective in our centre. However, careful patient selection and acquiring the necessary advanced laparoscopic surgical skills coupled with the proper use of equipment are mandatory before embarking on this procedure.

  16. Should all distal pancreatectomies be performed laparoscopically?

    2009-01-01

    Despite the relatively slow start of laparoscopic pancreatectomy relative to other laparoscopic resections, an increasing number of these procedures are being performed around the world. Operations that were once considered impossible to perform laparoscopically, such as pancreaticoduodenectomy and central pancreatectomy are gaining momentum. Technology continues to improve, as does surgical experience and prowess. There are both enough experience and data (though retrospective) to confirm that LDP with or without spleen preservation appears to be a safe treatment for benign or noninvasive lesions of the pancreas. Based on the fact that LDP can be performed with similar or shorter operative times, blood loss, complication rates, and length of hospital stay than ODP, it can be recommended as the treatment of choice for benign and noninvasive lesions in experienced hands when clinically indicated. It is very difficult to make clear recommendations with regard to laparoscopic resection of malignant pancreatic tumors due to the lack of conclusive data. As long as margins are negative and lymph node clearance is within accepted standards, LDP appears to have no untoward oncologic effects on outcome. Certainly more data, preferably in the manner of a randomized clinical trial, are needed before additional recommendations can be made. Potential benefits of laparoscopic resection for cancer include the ability to inspect the abdomen and abort the procedure with minimal damage if occult metastases are identified. This does not delay the onset of palliative chemotherapy, which would be the primary treatment in that circumstance. In fact, there is evidence to suggest that there is a greater likelihood of receiving systemic therapy if a laparotomy is avoided in patients who have radiologically occult metastases. Patients may also undergo palliative laparoscopic gastric and biliary bypass if indicated. Faster wound healing may also translate into a shorter waiting time before

    Full Text Available Video-based smoke detection in laparoscopic surgery has different potential applications, such as the automatic addressing of surgical events associated with the electrocauterization task and the development of automatic smoke removal. In the literature, video-based smoke detection has been studied widely for fire surveillance systems. Nevertheless, the proposed methods are insufficient for smoke detection in laparoscopic videos because they often depend on assumptions which rarely hold in laparoscopic surgery such as static camera. In this paper, ten visual features based on motion, texture and colour of smoke are proposed and evaluated for smoke detection in laparoscopic videos. These features are RGB channels, energy-based feature, texture features based on gray level co-occurrence matrix (GLCM, HSV colour space feature, features based on the detection of moving regions using optical flow and the smoke colour in HSV colour space. These features were tested on four laparoscopic cholecystectomy videos. Experimental observations show that each feature can provide valuable information in performing the smoke detection task. However, each feature has weaknesses to detect the presence of smoke in some cases. By combining all proposed features smoke with high and even low density can be identified robustly and the classification accuracy increases significantly.

    Music education affects the mathematical and visuo-spatial skills of school-age children. Visuo-spatial abilities have a significant effect on laparoscopic suturing performance. We hypothesize that prior music experience influences the performance of laparoscopic suturing tasks. Thirty novices observed a laparoscopic suturing task video. Each performed 3 timed suturing task trials. Demographics were recorded. A repeated measures linear mixed model was used to examine the effects of prior music experience on suturing task time. Twelve women and 18 men completed the tasks. When adjusted for video game experience, participants who currently played an instrument performed significantly faster than those who did not (PMen who had never played an instrument or were currently playing an instrument performed better than women in the same group (P=0.002 and P<0.001). There was no sex difference in the performance of participants who had played an instrument in the past (P=0.29). This study attempted to investigate the effect of music experience on the laparoscopic suturing abilities of surgical novices. The visuo-spatial abilities used in laparoscopic suturing may be enhanced in those involved in playing an instrument.

    Full Text Available Background: A prospective case series of single incision multiport laparoscopic colorectal resections for malignancy using conventional laparoscopic trocars and instruments is described. Materials and Methods: Eleven patients (seven men and four women with colonic or rectal pathology underwent single incision multiport laparoscopic colectomy/rectal resection from July till December 2010. Four trocars were placed in a single transumblical incision. The bowel was mobilized laparoscopically and vessels controlled intracorporeally with either intra or extracorporeal anastomosis. Results: Three patients had carcinoma in the caecum, one in the hepatic flexure, two in the rectosigmoid, one in the descending colon, two in the rectum and two had ulcerative pancolitis (one with high grade dysplasia and another with carcinoma rectum. There was no conversion to standard multiport laparoscopy or open surgery. The median age was 52 years (range 24-78 years. The average operating time was 130 min (range 90-210 min. The average incision length was 3.2 cm (2.5-4.0 cm. There were no postoperative complications. The average length of stay was 4.5 days (range 3-8 days. Histopathology showed adequate proximal and distal resection margins with an average lymph node yield of 25 nodes (range 16-30 nodes. Conclusion: Single incision multiport laparoscopic colorectal surgery for malignancy is feasible without extra cost or specialized ports/instrumentation. It does not compromise the oncological radicality of resection. Short-term results are encouraging. Long-term results are awaited.

    1991-07-01

    Most general surgeons are familiar with monopolar electrocautery, but few are equally comfortable with laser dissection and coagulation. At courses across the country, surgeons are being introduced to laparoscopy and laser use in one and two day courses, and are certified from that day forward as laser laparoscopists. Some surgeons are told that laser and electrosurgery may be equally acceptable techniques for performance of laparoscopic surgery, but that a surgeon may double his patient volume by advertising 'laser laparoscopic cholecystectomy.' The sale of certain lasers has skyrocketed on the basis of such hype. The only surprise is that laparoscopic cholecystectomy complications occurring in this country seem to be more closely related to the laparoscopic access and visualization than to the choice of laser of electrocautery as the preferred instrument for thermal dissection. The purpose of this article is to: 1) Discuss the physics and tissue effects of electrosurgery and laser; 2) compare the design and safety of electrosurgical and laser delivery systems; and 3) present available data comparing laser and electrocautery application in laparoscopic cholecystectomy.

    Since last two decades minimally invasive techniques have revolutionized surgical field. In 2003 Pomel first described laparoscopic pelvic exenteration, since then very few reports have described minimally invasive approaches for total pelvic exenteration. We report the 10 cases of locally advanced rectal adenocarcinoma which were operated between the periods from March 1, 2017 to November 11, 2017 at the Tata Memorial Hospital, Mumbai. All male patients had lower rectal cancer with prostate involvement on magnetic resonance imaging (MRI). One female patient had uterine and fornix involvement. All perioperative and intraoperative parameters were collected retrospectively from prospectively maintained electronic data. Nine male patients with diagnosis of nonmetastatic locally advanced lower rectal adenocarcinoma were selected. All patients were operated with minimally invasive approach. All patients underwent abdominoperineal resection with permanent sigmoid stoma. Ileal conduit was constructed with Bricker's procedure through small infraumbilical incision (4-5 cm). Lateral pelvic lymph node dissection was done only when postchemoradiotherapy MRI showed enlarged pelvic nodes. All 10 patients received neoadjuvant chemo radiotherapy, whereas 8 patients received additional neoadjuvant chemotherapy. Mean body mass index was 21.73 (range 19.5-26.3). Mean blood loss was 1000 mL (range 300-2000 mL). Mean duration of surgery was 9.13 hours (range 7-13 hours). One patient developed paralytic ileus, which was managed conservatively. One patient developed intestinal obstruction due to herniation of small intestine behind the left ureter and ileal conduit. The same patient developed acute pylonephritis, which was managed with antibiotics. Mean postoperative stay was 14.6 days (range 9-25 days). On postoperative histopathology, all margins were free of tumor in all cases. Minimally invasive approaches can be used safely for total pelvic exenteration in locally advanced

    Laparoscopic surgery has established itself as the approach of choice for a multitude of operations in general, urological, and gynecological surgery. A number of factors make performing laparoscopic surgery technically demanding, and as such it is crucial that surgical trainees hone their skills safely on trainers before operating on patients. These can be highly expensive. Here, we describe a novel and upgradable approach to constructing an affordable laparoscopic trainer. A pattern was produced to build an upgradable laparoscopic trainer for less than $100. The basic model was constructed from an opaque plastic crate with plywood base, 2 trocars, and 2 pairs of disposable laparoscopic instruments. A laptop, a light emitting diode (LED), and a fixed webcam were utilized to visualize the box interior. An enhanced version was also created, as an optional upgrade to the basic model, featuring a neoprene-trocar interface and a simulated mobile laparoscope. The described setup allowed trainees to gain familiarity with laparoscopic techniques, beginning with simple manipulation and then progressing through to more relevant procedures. Novices began by moving easy-to-grasp objects between containers and then attempting more challenging manipulations such as stacking sugar cubes, excising simulated lesions, threading circular mints onto cotton, and ligating fastened drinking straws. These techniques have introduced the necessity of careful instrument placement and have increased trainees' dexterity with laparoscopy. Here, we have outlined an upgradable and affordable alternative laparoscopic trainer that has given many trainees crucial experience with laparoscopic techniques, allowing them to safely improve their manual skill and confidence.

    Full Text Available The objective of the experiment reported here was to investigate and compare the amino acid (AA digestibility of distillers' dried grains (DDG, distillers' dried grains with solubles (DDGS, high protein distillers' dried grains (HP-DDG, and high protein distillers' dried grains with solubles (HP-DDGS in growing pigs. Five semi-purified diets consisting of DDG, DDGS, HP-DDG, HP-DDGS, and nitrogen-free diet (NFD were fed to pigs fitted with simple T-cannula for 5 observations per diet. Endogenous losses of AA at the terminal ileum of pigs that received the NFD were used to calculate standardized ileal digestibility (SID of AA from apparent ileal digestibility (AID of AA. The AID of Lys in DDGS was lower (P < 0.05 than that in DDG, which was also lower (P < 0.05 than that in HP-DDG. There were no differences in AID of Met among DDG, DDGS and HP-DDGS, but was greater (P < 0.05 in HP-DDG than in DDG or DDGS. The AID of Thr in HP-DDG was greater (P < 0.05 than that in DDGS but not different from that in DDG or HP-DDGS. The branched-chain AA Ile and Leu had greater (P < 0.05 AID in HP-DDG than in DDG, DDGS or HP-DDGS, and there was no difference among DDG, DDGS, and HP-DDGS. The AID of Trp in DDG and DDGS or HP-DDG and HP-DDGS were not different, but the AID of Trp in HP-DDGS was greater (P < 0.05 than that of DDGS. The greatest SID of the indispensable AA was in HP-DDG. Except for Arg and Lys in which DDG had greater (P < 0.05 digestibility, there was no difference between DDG and DDGS in the SID of the indispensable AA. The SID of Lys in DDG was greater (P < 0.05 than that of DDGS but there was no difference between that of DDG and HP-DDGS. Only His, Ile, and Met had lower (P < 0.05 SID in HP-DDGS than HP-DDG within the indispensable AA. The SID of Ala, Asp, Cys, Glu, Gly, Ser and Tyr were lower (P < 0.05 in DDGS than in HP-DDG. There SID of dispensable AA in DDG was not different from that of HP-DDGS. The current study provided

    Gastro-intestinal neuroendocrine tumors (GI-NETs) are rare neoplasms, frequently metastatic, raising difficult clinical and therapeutic challenges due to a poor knowledge of their biology. As neuroendocrine cells express both epithelial and neural cell markers, we studied the possible involvement in GI-NETs of axon guidance molecules, which have been shown to decrease tumor cell proliferation and metastatic dissemination in several tumor types. We focused on the role of Semaphorin 3F (SEMA3F) in ileal NETs, one of the most frequent subtypes of GI-NETs. SEMA3F expression was detected in normal neuroendocrine cells but was lost in most of human primary tumors and all their metastases. SEMA3F loss of expression was associated with promoter gene methylation. After increasing endogenous SEMA3F levels through stable transfection, enteroendocrine cell lines STC-1 and GluTag showed a reduced proliferation rate in vitro. In two different xenograft mouse models, SEMA3F-overexpressing cells exhibited a reduced ability to form tumors and a hampered liver dissemination potential in vivo. This resulted, at least in part, from the inhibition of mTOR and MAPK signaling pathways. This study demonstrates an anti-tumoral role of SEMA3F in ileal NETs. We thus suggest that SEMA3F and/or its cellular signaling pathway could represent a target for ileal NET therapy. PMID:26447612

    Full Text Available Laparoscopic inguinal herniorraphy via a transabdominal preperitoneal (TAPP approach using Polypropylene Mesh (Mesh and staples is an accepted technique. Mesh induces a localised inflammatory response that may extend to, and involve, adjacent abdominal and pelvic viscera such as the appendix. We present an interesting case of suspected Mesh-induced appendicitis treated successfully with laparoscopic appendicectomy, without Mesh removal, in an elderly gentleman who presented with symptoms and signs of acute appendicitis 18 months after laparoscopic inguinal hernia repair. Possible mechanisms for Mesh-induced appendicitis are briefly discussed.

    Full Text Available Introduction. The elbow interposition arthroplasty is a very common procedure performed mainly on active young patients who need great functionality and for whom total joint replacement is contraindicated and arthrodesis is noncompliant. We are going to demonstrate a case of a 34-year-old male suffering from malunion of the distal humerus, elbow stiffness, and manifest signs of arthrosis of the dominant limb, treated with the IA Grika technique at a 5-year follow-up. Patients and Methods. The chosen criteria to evaluate the injured side and the uninjured side during the clinical and radiological follow-up were the objective function and related quality of life, measured by the Mayo Elbow Performance Score (MEPS, and postoperative complications. To assess flexion and supination forces and elbow muscular strength, a hydraulic dynamometer was used. Results. At a 5-year follow-up, the results were excellent as during the first year. Conclusions. The Grika technique is a valid and feasible option in the treatment of elbow injuries.

    Phytase is well studied and explored, however, little is known about its effects on the microbial ecology of the gastrointestinal tract. In total, 400 one-day-old female Ross 308 chicks were randomly distributed to four experimental groups. The dietary treatments were arranged as a 2 × 2 complete factorial design, with the factors being adequate (PC) or insufficient calcium (Ca) and digestible phosphor (dP)(NC) and with or without 5000 phytase units (FTU)/kg of Escherichia coli 6-phytase. The gastrointestinal tract pH values, ileal microbial communities and short-chain fatty acid concentrations in the digesta were determined. The reduction in Ca and dP concentration significantly affected pH in the crop and caeca, and addition of phytase to the NC resulted in a pH increase in the ileum. The reduction in Ca and dP concentration significantly lowered, while phytase supplementation increased ileal total bacterial counts. Additionally, the deficient diet reduced butyrate- but increased lactate-producing bacteria. The addition of phytase increased Lactobacillus sp./Enterococcus sp. whereas in case of Clostridium leptum subgroup, Clostridium coccoides-Eubacterium rectale cluster, Bifidobacterium sp. and Streptococcus/Lactococcus counts, a significant Ca and dP level x phytase interaction was found. However, the recorded interactions indicated that the effects of phytase and Ca and dP levels were not consistent. Furthermore, the reduction of Ca and dP level lowered Clostridium perfringens and Enterobacteriaceae counts. The analysis of fermentation products showed that reducing the Ca and dP content in the diet reduced total SCFA, DL-lactate, and acetic acid in the ileum whereas phytase increased concentrations of these acids in the NC group. This suggests that P is a factor which limits fermentation in the ileum. It may be concluded that phytase plays a role in modulating the gut microbiota of chicken, however, this is clearly linked with the levels of P and Ca in a diet.

    Full Text Available Single-incision laparoscopic surgery is an alternative to conventional multiport laparoscopy. Single-access laparoscopy using a transumbilical port affords maximum cosmetic benefits because the surgical incision is hidden in the umbilicus. The advantages of single-access laparoscopic surgery may include less bleeding, infection, and hernia formation and better cosmetic outcome and less pain. The disadvantages and limitations include longer surgery time, difficulty in learning the technique, and the need for specialized instruments. Ongoing refinement of the surgical technique and instrumentation is likely to expand its role in gynecologic surgery in the future. We perform single-incision total laparoscopic hysterectomy using three ports in the single transumbilical incision.

    Full Text Available Laparoscopy has made a revolution in surgical procedures and treatment of various diseases but its complications are still under investigation. Intra-abdominal visceral and vessel injuries, trocar site hernia, and leaving foreign bodies into the peritoneal cavity are among some laparoscopic surgery complications. This is a rare report of Penrose drain migration following incomplete laparoscopic Fundoplication surgery. The patient was a 47- year- old woman, who was a candidate for Touplet Fundoplication via laparoscopic approach due to refractory gastro-esophageal reflux disease (GERD. While wrapping a Penrose drain around the esophagus, the patient had a cardiorespiratory arrest. Attempts to remove the Penrose drain were unsuccessful and the surgical procedure was terminated due to patient's condition. Four months later, after a long period of dysphagia and abdominal pain, the Penrose drain was defecated via rectum.

    Minimally invasive surgery has been replacing the open standard technique in several procedures. Similar or even better postoperative outcomes have been described in laparoscopic or robot-assisted procedures when compared to open surgery. Moreover, minimally invasive surgery has been providing less postoperative pain, shorter hospitalization, and thus a faster return to daily activities. However, the learning curve required to obtain laparoscopic expertise has been a barrier in laparoscopic spreading. Laparoscopic surgery training laboratory has been developed to aid surgeons to overcome the challenging learning curve. It may include tutorials, inanimate model skills training (box models and virtual reality simulators), animal laboratory, and operating room observation. Several different laparoscopic courses are available with specific characteristics and goals. Herein, we aim to describe the activities performed in a dry and animal-model training laboratory and to evaluate the impact of different kinds of laparoscopic surgery training courses on surgeon’s performance. Several tasks are performed in dry and animal laboratory to reproduce a real surgery. A short period of training can improve laparoscopic surgical skills, although most of times it is not enough to confer laparoscopic expertise for participants. Nevertheless, this short period of training is able to increase the laparoscopic practice of surgeons in their communities. Full laparoscopic training in medical residence or fellowship programs is the best way of stimulating laparoscopic dissemination. PMID:27933135

    Full Text Available Objectives: The most common indication for abdominal surgery in elderly (65 & older is gallstone disease.The elderly are more prone to complication of such surgery due to their other co-morbidity and thus they may benefit mostly from a safer method of surgical procedure. The purpose of this study was to evaluate the safety and outcome of laparoscopic cholecystectomy in elderly compare to the conventional method. Methods & Materials: Via prospective study from June 2005 to March 2008 included all patient older than 60 years of age who underwent cholecystectomy by open (Group A and laparoscopic (Group B method in Milad Hospital.The demographic data (sex age, American Society of Anesthesiologists’ (ASA score, postoperative mortality morbidity, length of stay and operative time were recorded for each patient and were compared between two methods. Data of patient’s analysis by SPSS with chi-square and t test. Results: The study included 311 elderlies (34% men and 66% women. Hundred fifty-seven patients underwent open cholecystectomy; 154 patients underwent laparoscopic cholecystectomy. The mean age was 7141 years. The outcome in group B (laparoscopic included: morality 0%, morbidity 2%, postoperative hospital stay 1 days, mean operation time was 40 minutes. In group A(open: mortality and morbidity rate were 21% and 12% respectively with postoperative hospital stay 331 days and similar operation time as group A. Conclusion: Laparoscopic cholecystectomy is the gold standard treatment and safe procedure in elderly patient and aging is not considered to be a contraindication laparoscopic surgery in such patients.

    Full Text Available Background. After more than decade of routine use of laparoscopic cholecystectomy for treatment of symptomatic gallbladder stones, the incidence of biliary injuries, which are potentially life threatening and cause prolonged hospitalization and major morbidity, seems to be increased in laparoscopic cholecystectomy compared with open operation. Injury rate was from some reports 2.5 to 4 times higher than with open operation. There are many proposed classifications of types of biliary injuries.The most frequent direct causes of laparoscopic biliary injury are misidentification of the common bile duct, cautery injuries to the bile duct and improper application of clips to the cystic duct.Conclusions. To avoid misidentification of ducts one should conclusively identify cystic duct and artery, the structures to be divide, in every laparoscopic cholecystectomy. To achieve that goal, Calot’s triangle must be dissected free of fat and fibrous – tissue and the lower end of the gallbladder must be dissected of the liver bed. The only two structures entering the gallbladder should be visible – cystic duct and artery. With avoidance of blind application of cautery and clips to control bleeding one should avoid injury of bile duct. Low cautery settings should be used in portal dissections to prevent arc.With meticulous care in dissection and conclusive identification of cystic duct and artery we can prevent injuries of bile duct, which still have impermissible high incidence. In the article 504 laparoscopic cholecystectomies performed at the Department of abdominal surgery in BPD in 2002 were analysed. We follow priciples of safety in laparoscopic cholecystectomy. There were no biliary injuries reports.

    Background There are scant data in the literature regarding the role of robotic liver surgery. The aim of the present study was to develop techniques for robotic liver tumour resection and to draw a comparison with laparoscopic resection. Methods Over a 1-year period, nine patients underwent robotic resection of peripherally located malignant lesions measuring <5 cm. These patients were compared prospectively with 23 patients who underwent laparoscopic resection of similar tumours at the same institution. Statistical analyses were performed using Student's t-test, χ2-test and Kaplan–Meier survival. All data are expressed as mean ± SEM. Results The groups were similar with regards to age, gender and tumour type (P = NS). Tumour size was similar in both groups (robotic −3.2 ± 1.3 cm vs. laparoscopic −2.9 ± 1.3 cm, P = 0.6). Skin-to-skin operative time was 259 ± 28 min in the robotic vs. 234 ± 17 min in the laparoscopic group (P = 0.4). There was no difference between the two groups regarding estimated blood loss (EBL) and resection margin status. Conversion to an open operation was only necessary in one patient in the robotic group. Complications were observed in one patient in the robotic and four patients in the laparoscopic groups. The patients were followed up for a mean of 14 months and disease-free survival (DFS) was equivalent in both groups (P = 0.6). Conclusion The results of this initial study suggest that, for selected liver lesions, a robotic approach provides similar peri-operative outcomes compared with laparoscopic liver resection (LLR).

    Full Text Available For choledocholithiasis, endoscopic management is the first line of treatment. Both Dormia basket and balloon catheter are used to retrieve common bile duct (CBD stones. Here we present a case of impaction of the Dormia basket during an endoscopic procedure. The patient was managed through laparoscopic choledochotomy, and the basket was found to be impacted with a common bile stone of size 18 mm. The stone was disengaged from the basket and, by holding the tip of the basket, was removed through one of the laparoscopic ports.

    2018-04-01

    Esophageal achalasia is a primary esophageal motility disorder defined by the lack of esophageal peristalsis, and by a lower esophageal sphincter that fails to relax in response to swallowing. Patients' symptoms include dysphagia, regurgitation, aspiration, heartburn, and chest pain. Achalasia is a chronic condition without cure, and treatment options are aimed at providing symptomatic relief, improving esophageal emptying, and preventing the development of megaesophagus. Presently, a laparoscopic Heller myotomy with a partial fundoplication is considered the best treatment modality. A properly executed operation is key for the success of a laparoscopic Heller myotomy.

    2006-01-01

    Full Text Available We had a 14 year old boy, who presented with recurrent attacks of right loin pain. Investigations revealed a retrocaval ureter. A transperitoneal three port laparoscopic approach was undertaken. The retrocaval portion of ureter was excised. A double J stent was placed laparoscopically and ureteroureterostomy was done with intracorporeal suturing. The patient was discharged after 72 hours and the stent was removed on the 15th day. Follow up showed regression of hydronephrosis. We recommend this approach compared to open surgery, as it offers several advantages compared to conventional open surgery like decreased postoperative pain, decreased hospital stay and a cosmetically more acceptable surgical scar.

    Placement of enteral feeding tubes is an important part of a surgeon's skill base. Surgical insertion of feeding tubes has been performed safely for many years with very few modifications. With the recent surge in interest and applicability of other laparoscopic procedures, it is well within the skills of the average laparoscopic surgeon to insert feeding tubes. We describe herein a simple technique for the insertion of the Moss feeding tube. The procedure described has a minimum of invasion, along with simplicity, safety, and accuracy.

    Spleen injury appears in 10% to 30% of abdominal trauma patients. Mortality among the patients in the last 20 years remains high (6% to 7%) and shows no tendency to decline. Nowadays nonoperative management is widely accepted management of patients with low-grade spleen injury, whereas management of patients with high-grade spleen injury (III and higher) is not so obvious. There are 3 methods exist in treatment of such patients: conservative (with or without angioembolization), spleen-preserving operations, and splenectomy. Today laparoscopic splenectomy is not a widely used operation and only few studies reported about successful use of laparoscopic splenectomy in patients with spleen injury.The aim of the study was to determine indications and contraindications for laparoscopic splenectomy in abdominal trauma patients and to analyze results of the operations. The study involved 42 patients with spleen injury grade III who were admitted in our institute in the years of 2010 to 2014. The patients were divided in 2 groups. Laparoscopic splenectomy was performed in 23 patients (group I) and "traditional" splenectomy was carried out in 19 patients (group II). There was no difference in the demographic data and trauma severity between the 2 groups. Noninvasive investigations, such as laboratory investigations, serial abdominal ultrasound examinations, x-ray in multiple views, and computed tomography had been performed before the decision about necessity of an operation was made. Patients after laparoscopic operations had better recovering conditions compared with patients with the same injury after "traditional" splenectomy. Neither surgery-related complications nor mortalities were registered in both groups. Laparoscopic splenectomy was more time-consuming operation than "traditional" splenectomy. We suggest that as experience of laparoscopic splenectomy is gained the operation time will be reduced. Laparoscopic splenectomy is a safe feasible operation in patients

  2. Organic Solute Transporter α-β Protects Ileal Enterocytes From Bile Acid–Induced InjurySummary

    Directory of Open Access Journals (Sweden)

    Courtney B. Ferrebee

    Full Text Available Background & Aims: Ileal bile acid absorption is mediated by uptake via the apical sodium-dependent bile acid transporter (ASBT, and export via the basolateral heteromeric organic solute transporter α-β (OSTα-OSTβ. In this study, we investigated the cytotoxic effects of enterocyte bile acid stasis in Ostα-/- mice, including the temporal relationship between intestinal injury and initiation of the enterohepatic circulation of bile acids. Methods: Ileal tissue morphometry, histology, markers of cell proliferation, gene, and protein expression were analyzed in male and female wild-type and Ostα-/- mice at postnatal days 5, 10, 15, 20, and 30. Ostα-/-Asbt-/- mice were generated and analyzed. Bile acid activation of intestinal Nrf2-activated pathways was investigated in Drosophila. Results: As early as day 5, Ostα-/- mice showed significantly increased ileal weight per length, decreased villus height, and increased epithelial cell proliferation. This correlated with premature expression of the Asbt and induction of bile acid–activated farnesoid X receptor target genes in neonatal Ostα-/- mice. Expression of reduced nicotinamide adenine dinucleotide phosphate oxidase-1 and Nrf2–anti-oxidant responsive genes were increased significantly in neonatal Ostα-/- mice at these postnatal time points. Bile acids also activated Nrf2 in Drosophila enterocytes and enterocyte-specific knockdown of Nrf2 increased sensitivity of flies to bile acid–induced toxicity. Inactivation of the Asbt prevented the changes in ileal morphology and induction of anti-oxidant response genes in Ostα-/- mice. Conclusions: Early in postnatal development, loss of Ostα leads to bile acid accumulation, oxidative stress, and a restitution response in ileum. In addition to its essential role in maintaining bile acid homeostasis, Ostα-Ostβ functions to protect the ileal epithelium against bile acid–induced injury. NCBI Gene Expression Omnibus: GSE99579.

    Laparoscopic splenectomy for massive splenomegaly is still a controversial procedure as compared with open splenectomy. We aimed to compare the feasibility of laparoscopic splenectomy versus open splenectomy for massive splenomegaly from different surgical aspects in children. The data of children aged splenectomy for hematologic disorders were retrospectively reviewed in 2 pediatric surgery centers from June 2004 until July 2012. The study included 32 patients, 12 who underwent laparoscopic splenectomy versus 20 who underwent open splenectomy. The mean ages were 8.5 years and 8 years in the laparoscopic splenectomy group and open splenectomy group, respectively. The mean operative time was 180 minutes for laparoscopic splenectomy and 120 minutes for open splenectomy. The conversion rate was 8%. The mean amount of intraoperative blood loss was 60 mL in the laparoscopic splenectomy group versus 110 mL in the open splenectomy group. Postoperative atelectasis developed in 2 cases in the open splenectomy group (10%) and 1 case in the laparoscopic splenectomy group (8%). Oral feeding postoperatively resumed at a mean of 7.5 hours in the laparoscopic splenectomy group versus 30 hours in the open splenectomy group. The mean hospital stay was 36 hours in the laparoscopic splenectomy group versus 96 hours in the open splenectomy group. Postoperative pain was less in the laparoscopic splenectomy group. Laparoscopic splenectomy for massive splenomegaly in children is safe and feasible. Although the operative time was significantly greater in the laparoscopic splenectomy group, laparoscopic splenectomy was associated with statistically significantly less pain, less blood loss, better recovery, and shorter hospital stay. Laparoscopic splenectomy for pediatric hematologic disorders should be the gold-standard approach regardless of the size of the spleen.

    Schwannomas are usually benign tumors attached to peripheral nerves and are rarely found in the gastrointestinal tract. Schwannomas in the porta hepatis are extremely rare, with only 15 cases described in the literature to date. A 22-year-old female patient presented with colicky upper abdominal pain lasting 3 months. Magnetic resonance imaging of the abdominal cavity revealed a tumor in the porta hepatis. The patient was qualified for laparoscopy. The tumor was totally excised laparoscopically under guidance of laparoscopic ultrasound without intra- or postoperative complications. Postoperative histopathological examination confirmed the porta hepatic schwannoma. The patient recovered uneventfully with very good cosmetic results. In the follow-up period of 5 months we have not observed any abdominal or general health problems. The present case is the first report in the world of laparoscopic ultrasound guided laparoscopic excision of a porta hepatic schwannoma.

    Laparoscopic surgery is applied today worldwide to most digestive procedures. In some of them, such as cholecystectomy, Nissen’s fundoplication or obesity surgery, laparoscopy has become the standard in practice. In others, such as colon or gastric resection, the laparoscopic approach is frequently used and its usefulness is unquestionable. More complex procedures, such as esophageal, liver or pancreatic resections are, however, more infrequently performed, due to the high grade of skill necessary. As a result, there is less clinical evidence to support its implementation. In the recent years, robot-assisted laparoscopic surgery has been increasingly applied, again with little evidence for comparison with the conventional laparoscopic approach. This review will focus on the complex digestive procedures as well as those whose use in standard practice could be more controversial. Also novel robot-assisted procedures will be updated.

    Methane has been associated with constipation-predominant irritable bowel syndrome, slowing intestinal transit time by augmenting contractile activity. However, the precise mechanism underlying this effect remains unclear. Therefore, we investigated the mechanisms underlying the effect of methane on contractile activity, and whether such effects are mediated by nerve impulses or muscular contraction. We connected guinea pig ileal muscle strips to a force/tension transducer and measured amplitudes of contraction in response to electrical field stimulation (EFS; 1, 2, 8, 16 Hz) following methane infusion in the presence of tetradotoxin (TTX), atropine, guanethidine, or GR 113808. We then performed calcium imaging using Oregon Green 488 BAPTA-1 AM in order to visualize changes in calcium fluorescence in response to EFS following methane infusion in the presence of TTX, atropine, or a high K + solution. Methane significantly increased amplitudes of contraction (PMethane-induced increases in amplitude were inhibited when lower-frequency (1, 2 Hz) EFS was applied following atropine infusion (PMethane significantly increased calcium fluorescence, while this increase was attenuated following atropine infusion (Pmethane infusion. The actions of methane on the intestine are influenced by the cholinergic pathway of the enteric nervous system. Our findings support the classification of methane as a gasotransmitter. © 2017 John Wiley & Sons Ltd.

    The aim of this literature review was to analyse the advantages and disadvantages of a traditional ileal conduit (IC) with separate colostomy technique compared to the outcomes of a double-barrelled wet colostomy (DBWC) technique. The former technique results in the formation of two stomas, and the latter results in the formation of one stoma. PubMed was searched electronically for articles on DBWC. Fifteen articles were retrieved and of them 13 were included in the literature review (350 patients). Of the articles, 3 directly compared DBWC to IC with colostomy. Review of 13 DBWC articles demonstrated perioperative mortality ranging between 0 and 11.1% and postoperative complications ranging from 0 to 100%. Three of the studies directly compared DBWC to IC with colostomy; median operating times and length of stay were shorter in DBWC patients (p colostomy technique, as it requires only one stoma. This literature review supports the use of the technically less challenging DBWC technique as a viable alternative to the traditional IC with colostomy technique. © 2016 S. Karger AG, Basel.

    Background. The aim of this study was to compare endosonography and manometry of the anal sphincters in patients after ileal pouch-anal anastomosis (IPAA). Patients and methods. Ten patients aged between 23 and 50 years with IPAA performed for ulcerative colitis were examined with anal endosonography (AES) and manometry. Results. AES visualised abnormal image of the internal anal sphincter (IAS) in 9 patients (90%). Defects of the external anal sphincter (EAS) and puborectalis muscle (PR) were shown in 4 patients (40%). In 5 patients (50%) correlation between endosonographic and manometric assessment for the all analysed muscles: IAS, EAS and PR was found. In 4 cases (40%) both methods correlated with the evaluation of the EAS only and in 1 patient (10%) no correlation was found. Correlation between both methods for the IAS was found in half of the patients (50%) while in the evaluation of the EAS and PR dynamic activity, it was found in 9 cases (90%). Conclusions. Anal endosonography and manometry allow us to assess the morphology as well as the function of the anal sphincters in patients with IPAA. The methods mentioned above show high correlation in the assessment of the EAS function (9 cases; 90%) whereas in the case of IAS, manometry frequently (5 patients; 50%) does not confirm endosonografically detected defects.

    Full Text Available The impact of Clostridium difficile infection (CDI on healthcare is becoming increasingly recognized as it represents a major cause of nosocomial diarrhea. A rising number of CDI cases and outbreaks have been reported worldwide. Here, we developed the pig ileal-ligated loop model for semi-quantitative analysis comparing temporal differential proteomes in C. difficile following in vivo incubation with in vitro growth using isobaric tags for relative and absolute quantification (iTRAQ. Proteins retrieved from the in vitro cultures and the loop contents after 4, 8, and 12 h in vivo incubation were subjected to in-solution digestion, iTRAQ labeling, two-dimensional liquid chromatography/tandem mass spectrometry and statistical analyses. From a total of 1152 distinct proteins identified in this study, 705 proteins were available for quantitative measures at all time points in both biological and technical replicates; 109 proteins were found to be differentially expressed. With analysis of clusters of orthologous group and protein-protein network interactions, we identified the proteins that might play roles in adaptive responses to the host environment, hence enhancing pathogenicity during CDI. This report represents the quantitative proteomic analysis of C. difficile that demonstrates time-dependent protein expression changes under conditions that mimic in vivo infection and identifies potential candidates for diagnostic or therapeutic measures.

    The effects of dietary supplementation with 2 recently developed feed additives on the composition of the mucosa-associated microbiota of the ileum were studied in growing broiler chickens. A total of 48 male 1-d-old broiler chickens of the Cobb 500 strain were distributed in 4 treatments with 2 replicates of 6 birds each. The 2 additives tested were a di-d-fructose dianhydride–enriched caramel (FC) and the garlic derivative propyl propane thiosulfonate (PTS-O). Dietary treatments were a control (commercial diet with no additive), INU (20 g inulin/kg diet), CAR (20 g FC/kg diet), and GAR (90 mgPTS-O/kg diet). As a result of this study, inulin supplementation resulted in lower (P Eubacterium rectale log10 number of copies respect to controls. Higher (P spp. revealed the presence of Bifidobacterium longum, Bifidobacterium pseudolongum, and Bifidobacterium pseudocatenulatum in samples from chickens fed the control and the PTS-O–supplemented diet. Bifidobacterium longum was exclusively found in poultry fed the control diet, whereas B. pseudocatenulatum was found only in poultry fed the PTS-O–supplemented diet. This study showed that both PTS-O and FC were able to modulate the composition of the ileal mucosa-associated microbiota of growing broiler chickens. Finally, in addition to B. pseudolongum, the presence of B. longum and B. pseudocatenulatum, species not previously described in intestinal samples of broilers, was also demonstrated.

    Full Text Available OBJECTIVE: To present the initial experience of videolaparoscopic nephrectomy in live renal donor. MATERIALS AND METHODS: In the period from April 2000 to August 2003, 50 left nephrectomies in live donor were performed by videolaparoscopy for transplantation. Twenty-eight patients were male (56% and 22 female (44%. Mean age was 37.2 years, and the mean body mass index (BMI was 27.1 kg/m². RESULTS: Mean surgical time was 179.5 minutes, and warm ischemia time of the graft was 3.79 minutes. The mean estimated bleeding was 141 mL. There was no need of blood transfusion or conversion to open surgery. In 42 cases (84%, the vascular portion of the graft was considered good by the recipient's surgical team and in all cases, the ureter was considered of proper size, though in one of them (2% its vascularization was considered improper. The transplanted kidneys produced urine still in the surgical room in 46 of the 50 transplantations considered. In only 2 cases opioid was required for analgesia. In average, 3.1 doses of dipyrone were used for each patient during hospital stay, and hospital discharge occurred, in average, after 3.2 days post-operatively. Two patients required re-operations and one of them evolved to death. CONCLUSIONS: The laparoscopic nephrectomy in live donor for renal transplantation is an alternative to conventional open surgery. In relation to the graft, no alteration, either anatomic or functional, was detected. Though there is already a large documentation in the international literature regarding this procedure, in our setting a prospective randomized study with the usual surgical study is still necessary in order to prove the advantages and disadvantages of the method.

    Laparoscopic nephrectomy for both benign and malignant diseases of kidney is increasingly being performed. We report our experience with the first 120 consecutive laparoscopic nephrectomy performed in our hospital. It is the retrospective analysis of a prospectively maintained database of 4 years period. The parameters examined included age, gender, indications, operative time, blood loss, intraoperative and post operative complications. Mean age of surgery was 59 years (rang 19-84years). The indications for surgery included solid renal masses (71 patients), non-functioning kidneys (43), and collecting system tumours (6). The mean operating time was 132 minutes (range 75-270), average blood loss was 209 ml (range 0-1090) and average hospital stay was 4.7days (range 2-20). Bleeding, bowel injury and poor progression of laparoscopic procedure were the reasons in 7 (5.8%) cases converted to open surgery. There was 1 (0.8%) perioperative mortality. Eight (6.6%) patients developed post operative complications. Laparoscopic nephrectomy has inherent benefits and may be considered an alternate therapeutic option for kidney diseases with acceptable morbidity

    2001-01-01

    Bladder injury is a complication of laparoscopic surgery with a reported incidence in the general surgery literature of 0.5% and in the gynecology literature of 2%. We describe how to recognize and treat the injury and how to avoid the problem. We report two cases of bladder injury repaired with a General Surgical Interventions (GSI) trocar and a balloon device used for laparoscopic extraperitoneal inguinal hernia repair. One patient had a prior appendectomy; the other had a prior midline incision from a suprapubic prostatectomy. We repaired the bladder injury, and the patients made a good recovery. When using the obturator and balloon device, it is important to stay anterior to the preperitoneal space and bladder. Prior lower abdominal surgery can be considered a relative contraindication to extraperitoneal laparoscopic hernia repair. Signs of gas in the Foley bag or hematuria should alert the surgeon to a bladder injury. A one- or two-layer repair of the bladder injury can be performed either laparoscopically or openly and is recommended for a visible injury. Mesh repair of the hernia can be completed provided no evidence exists of urinary tract infection. A Foley catheter is placed until healing occurs.

    Human perceptual capabilities related to the laparoscopic interaction paradigm are not well known. Its study is important for the design of virtual reality simulators, and for the specification of augmented reality applications that overcome current limitations and provide a supersensing to the surgeon. As part of this work, this article addresses the study of laparoscopic pulling forces. Two definitions are proposed to focalize the problem: the perceptual fidelity boundary, limit of human perceptual capabilities, and the Utile fidelity boundary, that encapsulates the perceived aspects actually used by surgeons to guide an operation. The study is then aimed to define the perceptual fidelity boundary of laparoscopic pulling forces. This is approached with an experimental design in which surgeons assess the resistance against pulling of four different tissues, which are characterized with both in vivo interaction forces and ex vivo tissue biomechanical properties. A logarithmic law of tissue consistency perception is found comparing subjective valorizations with objective parameters. A model of this perception is developed identifying what the main parameters are: the grade of fixation of the organ, the tissue stiffness, the amount of tissue bitten, and the organ mass being pulled. These results are a clear requirement analysis for the force feedback algorithm of a virtual reality laparoscopic simulator. Finally, some discussion is raised about the suitability of augmented reality applications around this surgical gesture.

    2010-06-01

    Laparoscopy is widely used in the surgical treatment of a number of diseases. Its advantages are generally believed to lie on its minimal invasiveness, better cosmetic outcome and shorter length of hospital stay based on surgical expertise and state-of-the-art equipment. Thousands of laparoscopic surgical procedures performed safely prove that mechanical ventilation during anaesthesia for laparoscopy is well tolerated by a vast majority of patients. However, the effects of pneumoperitoneum are particularly relevant to patients with underlying lung disease as well as to the increasing number of patients with higher-than-normal body mass index. Moreover, many surgical procedures are significantly longer in duration when performed with laparoscopic techniques. Taken together, these factors impose special care for the management of mechanical ventilation during laparoscopic surgery. The purpose of the review is to summarise the consequences of pneumoperitoneum on the standard monitoring of mechanical ventilation during anaesthesia and to discuss the rationale of using a protective ventilation strategy during laparoscopic surgery. The consequences of chest wall derangement occurring during pneumoperitoneum on airway pressure and central venous pressure, together with the role of end-tidal-CO2 monitoring are emphasised. Ventilatory and non-ventilatory strategies to protect the lung are discussed.

    The introduction of laparoscopic surgery (LS) can be considered the most important advancement in our specialty in the past 25 years. Despite its advantages, implementation and consolidation has not been homogenous, especially for advanced techniques. The aim of this study was to analyse the level of development and use of laparoscopic surgery in Spain at the present time and its evolution in recent years. During the second half of 2012 a survey was developed to evaluate different aspects of the implementation and development of LS in our country. The survey was performed using an electronic questionnaire. The global response rate was 16% and 103 heads of Department answered the survey. A total of 92% worked in the public system. A total of 99% perform basic laparoscopic surgery and 85,2% advanced LS. Most of the responders (79%) consider that the instruments they have available for LS are adequate and 71% consider that LS is in the right stage of development in their environment. Basic laparoscopic surgery has developed in our country to be considered the standard performed by most surgeons, and forms part of the basic surgical training of residents. With regards to advanced LS, although it is frequently used, there are still remaining areas of deficit, and therefore, opportunities for improvement. Copyright © 2013 AEC.

    Safe dissection of Calot's Triangle is important during the performance of laparascopic cholucystectomy. The purpose of the study is to determine the frequency of demonstrable Rouviere's sulcus in patients with symptomatic gall stones and its role in safe dissection in Calot's triangle. This is a prospective descriptive study design done in Department of surgery, Kathmandu Medical College Teaching Hospital from Jan 2013 to Jan 2015. Patients who were posted for laparoscopic cholecystectomy were included. During laparoscopy, Rouviere's sulcus was noted in the operative note and classified according to following: Type I: Open type was defined as a cleft in which the right hepatic pedicle was visualized and the sulcus was opened throughout its length. Type II: if the sulcus was open only at its lateral end. Type III If the sulcus was open only at its medial end. Type IV: Fused type was defined as one in which the pedicle was not visualized.  A total of 200 patients underwent laparoscopic cholecystectomy during period of 2 years. Out of which Rouviere's sulcus was visualized in 150 patients (75 %).Type I (open type) was commoner in 54%, type II in 12%, Type III in 9% and type IV (fused type) in 25%. Rouviere's Sulcus is an important extra biliary land mark for safe dissection of Calot's triangle during laparoscopic cholecystectomy.  Rouviere's Sulcus, Laparoscopic cholecystectomy, Bile duct injury.

    Achalasia is characterized by an incomplete relaxation of the lower esophageal sphincter. The best treatment is surgical and the laparoscopic approach may have good results. To assess the results of laparoscopic Heller myotomy among patients with achalasia. Prospective study of patients subjected to a laparoscopic Heller myotomy between 1995 and 2004. Clinical features, early and late operative results were assessed. Twenty seven patients aged 12 to 74 years (12 females) were operated. All had disphagia lasting for a mean of 32 months. Mean lower esophageal sphincter pressure ranged from 18 to 85 mmHg. Eight patients received other treatments prior to surgery but symptoms persisted or reappeared. The preoperative clinical score was 7. No patient died and no procedure had to be converted to open surgery. In a follow up of 21 to 131 months, all patients are satisfied with the surgical results and the postoperative clinical score is 1. Only one patient with a mega esophagus maintained a clinical score of six. In this series of patients, laparoscopic Heller myotomy was an effective and safe treatment for esophageal achalasia.

    For a surgeon who performed some of the first laparoscopic cholecystectomies, laparoscopic surgery is undoubtedly the main revolution in the last decade of this century. It is impossible not to be fascinated by the extraordinary changes introduced in our profession in less than 10 years. However, looking back in history, one realizes that laparoscopy is but one of those leaps forward that have always punctuated the evolution of our profession. Since the last century we have witnessed the advent of painless surgery, infectionless surgery, reconstructive surgery, microsurgery, surgery under extracorporeal circulation, organ replacement, and so on. We are in the time of scarless surgery, with no lengthy postoperative handicap. Maybe tomorrow will see surgery performed by remote-controlled robots and surgery at the molecule level. The laparoscopic revolution is particularly important because for the first time surgery no longer involves any physical contact between the surgeon's hand and the patient. Let us hope that this will not lead to total absence of a human relationship in the surgical operation. To avoid this possibility we must remain resolutely involved in the development of laparoscopic surgery; we must keep our minds open to the future advances of science and technology and integrate them in our operative procedures.

    Laparoscopic pancreatic surgery represents one of the most advanced applications for laparoscopic surgery currently in use. In the past, minimally invasive techniques were only used for diagnostic laparoscopy, staging of pancreatic cancer, and palliative procedures for unresectable pancreatic cancer. With new advances in technology and instrumentation, some sophisticated procedures are currently available, such as the Whipple procedure, one of the most sophisticated applications of minimally invasive surgery. A review of the literature shows that 146 laparoscopic Whipple procedures have been published worldwide since 1994. The authors analyzed blood loss, mean operating time, hospital stay, conversion rate, mean age, mortality rate, lymph nodes in the pathologic findings, follow up, and complications. Mean age was 59.1 years; mean operating time was 439 min. The average blood loss for the reviewed literature was 143 mL; median hospital stay was 18 days; conversion rate was 46%; number of lymph nodes in the pathologic findings was 19; and mortalities related to the procedure was low, 2 patients (1.3%) and the complication rate was 16% (23/46 patients). Complications included 2 hemorrhages, 4 bowel obstructions, 1 stress ulcer, 1 delay of gastric emptying, 4 pneumonias, and 11 leaks. This review demonstrates that the laparoscopic Whipple procedure is not only feasible but also safe, with low mortality and acceptable rates of complications.

    In order to assess ileal dysfunction in patients with complaints after pelvic radiation therapy, retention measurements and scintigraphic imaging with selenium 75 homocholic acid conjugated with taurine ( 75 Se-HCAT), combined with the carbon 14 clycochol breath test, were evaluated in 39 patients. In 22 patients without ileal resection the results of the 75 Se-HCAT test and the breath test differentiated between a normal functioning ileum (both tests negative) and ileal dysfunction as a cause of complaints (one or both tests positive). Among the patients with ileal dysfunction, the combination of both tests permitted those with bacterial overgrowth (breath test positive, 75 Se-HCAT negative) to be separated from patients with evidence of bile acid malabsorption ( 75 Se-HCAT positive, breath test positive or negative). In 17 patients with small-bowel resection, the 75 Se-HCAT test helped to estimate the severity of bile acid malabsorption with implications for therapy. In this group the breath test was false-negative in 7 cases with abnormal 75 Se-HCAT. Additional systematically performed scintigraphic imaging improved the accuracy of the 75 Se-HCAT test, revealing cases with prolonged colonic accumulation of the radiopharmaceutical, causing spurious retention values. In conclusion, assessment of ileal dysfunction by nuclear medicine techniques in post-irradiation conditions provides information about the aetiology and therefore the possibility of adjustment in the clinical management.

    Urinary tract obstruction and postoperative hydronephrosis are risk factor for renal function deterioration after orthotopic ileal neobladder construction. However, reports of relationship between transient hydronephrosis and renal function are limited. We assess the influence of postoperative transient hydronephrosis on renal function in patients with orthotopic ileal neobladder construction. Between January 2006 and June 2013, we performed radical cystectomy in 164 patients, and 101 received orthotopic ileal neobladder construction. This study included data available from 64 patients with 128 renal units who were enrolled retrospectively. The hydronephrosis grade of each renal unit scored 0-4. The patients were divided into 4 groups according to the grade of hydronephrosis: control, low, intermediate, and high. The grade of postoperative hydronephrosis was compared with renal function 1 month and 1 year after surgery. There were no significant differences in renal function before surgery between groups. One month after surgery, the presence of hydronephrosis was significantly associated with decreased renal function. However, 1 year after urinary diversion hydronephrosis grades were improved significantly, and renal function was comparable between groups. Postoperative hydronephrosis at 1 month had no significant influence on renal function 1 year after ileal neobladder construction. Limitations include retrospective design, short follow-up periods, and a sample composition. The presence of transient hydronephrosis immediately after surgery may have limited influence on renal function 1 year after ileal neobladder construction.

    Balloon dilatation of the oesophagus in children has been performed predominantly for treating strictures, which are the result of primary repair of oesophageal atresia, interposition surgery or restrictive Nissen's fundoplication. Reports of the use of this technique for alternative causes of stricture are few. To report our experience and success with balloon dilatation of strictures due to caustic ingestion, achalasia, oesophagitis, congenital stenosis, and epidermolysis bullosa (EB) and to make comparisons with our treatment of patients with primary repair of oesophageal atresia (OA), as well as with reports in the English language literature. Retrospective review of fluoroscopically guided balloon oesophageal dilatation procedures in 19 patients over a 5-year period, and comparison of those performed for OA repair complications with those due to other diseases. The average radiation dose, per procedure, was calculated by a medical physicist. Ten patients had strictures as a result of primary repair of OA. Three patients had stricture as a result of EB, two from achalasia, two from caustic injury, one due to an oesophageal web and one from reflux oesophagitis. Our results show that the technique can also be curative for the last group and that it may be used intermittently to alleviate symptoms in ongoing diseases. We have not experienced any complications and have also calculated that, even with prolonged use of multiple procedures, the radiation exposure is comparable to other radiological techniques. Patients with alternative causes for oesophageal stricture may be treated to resolution within 2 years using balloon dilatation. Ongoing diseases such as EB require ongoing dilatation, but balloon dilatation of strictures has been successful in alleviating swallowing difficulty. Patients with stricture from OA repair sometimes need ongoing dilatation. Radiation exposure for multiple procedures, over an extended period, is comparable to that from a single

    To evaluate mid-term results from using a silicone sheet for inter-positional arthroplasty in moderate or severe cases of osteoarthrosis of the temporo-mandibular joint (TMJ). To also determine any remaining indications from this method. This retrospective study included patients that underwent surgery between 2008 and 2016. Pre- and post-operative mouth opening (MO), according to inter-incisal distance (mm) and pain score (PS: 0=no pain to 4=very severe pain) were recorded for 24 patients. Patients were divided according to thickness of the silicone sheet (group A: 1.0 mm, group B: 1.5 mm). The cohort included 22 females (92%). Mean age at surgery was 55 years±13 (26-80). Mean length of follow-up was 26 months±24 (6-80). Mean improvement in MO was 8.2 mm (+33%) and of PS was 1.7 (-68%). MO was not improved for two patients and worsened for one. PS score improved for all patients. No statistical difference was found between groups A and B. There was also a tendency for degradation of outcomes over time. The poor reputation of prosthetic discoplasty was not as evident in our series, even though anatomical and functional status seemed to deteriorate over time. This is because total-joint prosthetic replacement is often proposed instead. However, for elderly or fragile patients that have severe pain, and regarding cost-benefit aspects, conventional arthroplasty can still be discussed, especially since French national health-care insurance does not yet support TMJ prosthetic replacement for osteoarthrosis.

    The anatomical and physiological changes after Roux-en-Y gastric bypass for morbid obesity can lead to severe hyperinsulinemic hypoglycemia with neuroglycopenia in a small percentage of patients. The exact physiologic mechanism is not completely understood. Surgical reversal to the original anatomy and distal or total pancreatectomy are current therapeutic options to reverse the hypoglycemic effect, with substantial associated morbidity. Our group reports a pilot clinical series of a novel surgical technique using one-anastomosis jejunal interposition with gastric remnant resection (Branco-Zorron Switch). Patients with severe symptomatic hyperinsulinemic hypoglycemia refractory to conservative therapy were treated using the technique. The procedure started with resection of the remnant stomach close to pylorus. The alimentary limb was sectioned at 20 cm from the gastrojejunal anastomosis, and the rest of the alimentary limb was resected until the Y-Roux anastomosis. A hand-sutured anastomosis was then performed with the proximal alimentary limb and the remnant antrum. Four patients were successfully submitted to the procedure with reversal of the symptomatology and normalization of insulin levels, postprandial glucose levels, and oral glucose tolerance test, with a mean follow-up of 24.3 months. Mean operative time was 188 min, and patients recovered without postoperative complications. Patients suffering from severe hyperinsulinemic hypoglycemia after gastric bypass may be efficiently treated by this innovative procedure, avoiding extreme surgical therapy such as pancreatectomy or restoring the gastric anatomy, while still maintaining sustained weight loss. Studies with larger series and longer follow-up are still needed to define the role of this therapy in managing this entity.

    Conventional laparoscopes provide a flat representation of the three-dimensional (3D) operating field and are incapable of visualizing internal structures located beneath visible organ surfaces. Computed tomography (CT) and magnetic resonance (MR) images are difficult to fuse in real time with laparoscopic views due to the deformable nature of soft-tissue organs. Utilizing emerging camera technology, we have developed a real-time stereoscopic augmented-reality (AR) system for laparoscopic surgery by merging live laparoscopic ultrasound (LUS) with stereoscopic video. The system creates two new visual cues: (1) perception of true depth with improved understanding of 3D spatial relationships among anatomical structures, and (2) visualization of critical internal structures along with a more comprehensive visualization of the operating field. The stereoscopic AR system has been designed for near-term clinical translation with seamless integration into the existing surgical workflow. It is composed of a stereoscopic vision system, a LUS system, and an optical tracker. Specialized software processes streams of imaging data from the tracked devices and registers those in real time. The resulting two ultrasound-augmented video streams (one for the left and one for the right eye) give a live stereoscopic AR view of the operating field. The team conducted a series of stereoscopic AR interrogations of the liver, gallbladder, biliary tree, and kidneys in two swine. The preclinical studies demonstrated the feasibility of the stereoscopic AR system during in vivo procedures. Major internal structures could be easily identified. The system exhibited unobservable latency with acceptable image-to-video registration accuracy. We presented the first in vivo use of a complete system with stereoscopic AR visualization capability. This new capability introduces new visual cues and enhances visualization of the surgical anatomy. The system shows promise to improve the precision and

    Full Text Available Background: Port site infection (PSI is an infrequent surgical site infection that complicates laparoscopic surgery but has a considerable influence in the overall outcome of laparoscopic cholecystectomy. The aim of this study was to evaluate factors that influence PSI after laparoscopic cholecystectomies and to analyze which of these factors can be modified to avoid PSI in a trail to achieve maximum laparoscopic advantages. Methods: A prospective descriptive qualitative study conducted on patients who underwent laparoscopic cholecystectomies. Swabs were taken for culture & sensitivity in all patients who developed PSI. Exploration under general anaesthesia, for patients, had deep surgical site infections and wound debridement was done, excisional biopsies had been taken for histopathological studies, and tissue samples for polymerase chain reaction for detection of mycobacterium tuberculosis was done. All patients were followed up for six months postoperatively. Factors as gender, site of infected port, type of microorganism, acute versus chronic cholecystitis, type of infection (superficial or deep infection and intraoperative spillage of stones, bile or pus were analyzed in our sample. Results: Port site infection rate was recorded in 40/889 procedures (4.5%, higher rates were observed in male patients 8/89 (8.9%, in acute cholecystitis 13/125 (10.4%, when spillage of bile, stones or pus occurred 24/80 (30%, and at epigastric port 32/40 (80%. Most of the PSI were superficial infections 77.5% with non-specific microorganism 34/40 (85%. Conclusion: There is a significant association of port site infection with spillage of bile, stones, or pus, with the port of gallbladder extraction and with acute cholecystitis. Especial consideration should be taken in chronic deep surgical site infection as mycobacterium tuberculosis could be the cause. Most of the PSIs are superficial and more common in males.

    Suprapubic hernia is the term to describe ventral hernias located less than 4 cm above the pubic arch in the midline. Hernias with an upper margin above the arcuate line encounter technical difficulties, and the differences in repair methods forced us to define them as large suprapubic hernias. To present our experience with laparoscopic repair of large suprapubic hernias that allows adequate mesh overlap. Nineteen patients with suprapubic incisional hernias who underwent laparoscopic repair between May 2013 and January 2015 were included in the study. Patients with laparoscopic extraperitoneal repair who had a suprapubic hernia with an upper margin below the arcuate line were excluded. Two men and 17 women, with a mean age of 58.2, underwent laparoscopic repair. Most of the incisions were midline vertical (13/68.4%). Twelve (63.1%) of the patients had previous incisional hernia repair (PIHR group); the mean number of previous incisional hernia repair was 1.4. Mean defect size of the PIHR group was higher than in patients without previous repair - 107.3 cm 2 vs. 50.9 cm 2 (p < 0.05). Mean operating time of the PIHR group was higher than in patients without repair - 126 min vs. 77.9 min (p < 0.05). Although all complications occurred in the PIHR group, there was no statistically significant difference. Laparoscopic repair of large suprapubic hernias can be considered as the first option in treatment. The low recurrence rates reported in the literature and the lack of recurrence, as observed in our study, support this view.

    Objectives: To evaluate the results of 160 consecutive laparoscopic cholecystectomy using sectorisation based port site selection to improve ergonomics for surgeons. Design: Descriptive study. Place and Duration of study: PNS Shifa Karachi, Pakistan from Feb 2011 to Feb 2012. Patients and Methods: In this prospective study, 160 consecutive patients had undergone laparoscopic cholecystectomy in a tertiary care hospital using sectorisation for trocar placement. All patients with symptomatic gallstones, acute calculous cholecystitis and empyema gallbladder were included. Patients with choledocholithiasis were excluded from the study. The collected data included age, sex, diagnosis, history of previous surgery, conversion to open surgery and its reasons, operative time, post-operative hospital stay, complications and laparoscopy related complications to the surgeon such as shoulder pain, wrist stress and pain, finger joint pain and stress exhaustion. Result: One hundred and sixty patients underwent laparoscopic cholecystectomy with mean age 45 +- 12.9 years. Female to male ratio was 7.8:1. A total of 110 patients had chronic cholecystitis / biliary colic, 34 patients were with acute cholecystitis and 16 patients had diagnosis of empyema gallbladder. The mean operative time was 35.3+-14.6 min. Conversion rate to open surgery was 1.2%. Complications included bleeding from cystic artery (n=1) and injury to common hepatic duct (CHD) (n=1). One patient developed port site hernia post operatively. There was no incidence of laparoscopy related complications in surgeon such as pain shoulder, strains on the wrist joint, stress exhaustion and hand-finger joint pain. Conclusion: Sectorisation technique can be used in laparoscopic cholecystectomy in order to avoid the physical constraints of laparoscopic shoulder, hand finger joint pain, tenosynovitis, stress exhaustion, and hand muscle injury without increasing any morbidity to the patients.

    The challenges in laparoscopic suturing include need to expertise to suture. Laparoscopic needle holder is a" key" instrument to accomplish this arduous task. The objective of this new invention was to develop a laparoscopic needle holder which would be adapted to avoid any wobble (with a shaft diameter same as a 5mm port), ensure accurate and dexterous suturing not just in adult patients but pediatric patients alike (with a short shaft diameter) and finally ensure seamless throw of knots with a narrow tip configuration. We did an initial evaluation to evaluate the validity of the prototype needle holder and its impact on laparoscopic suturing skills by experienced laparoscopic surgeons and novice laparoscopic Surgeons. Both the groups of surgeons performed two tasks. The first task was to grasp the needle and position it in an angle deemed ideal for suturing. The second task was to pass suture through two fixed points and make a single square knot. At the end of the tasks each participant was asked to complete a 5- point Likert's scale questionnaire (8 items; 4 items of handling and 4 items of suturing) rating each needle holder. In expert group, the mean time to complete task 1 was shorter with prototype 3/5 laparoscopic needle holder (11.8 sec Vs 20.8 sec). The mean time to complete task 2 was also shorter with prototype 3/5 laparoscopic needle holder (103.2 sec Vs 153.2 sec). In novice group, mean time to complete both the task was shorter with prototype 3/5 laparoscopic needle holder. The expert laparoscopic surgeons as well as novice laparoscopic surgeons performed laparoscopic suturing faster and with more ease while using the prototype 3/5 laparoscopic needle holder.

    AIM: To compare computed tomography enteroclysis (CTE) vs small intestine contrast ultrasonography (SICUS) for assessing small bowel lesions in Crohn's disease (CD), when using surgical pathology as gold standard. METHODS: From January 2007 to July 2008, 15 eligible patients undergoing elective resection of the distal ileum and coecum (or right colon) were prospectively enrolled. All patients were under follow-up. The study population included 6 males and 9 females, with a median age of 44 years (range: 18-80 years). Inclusion criteria: (1) certain diagnosis of small bowel requiring elective ileo-colonic resection; (2) age between 18-80 years; (3) elective surgery in our Surgical Unit; and (4) written informed consent. SICUS and CTE were performed ≤ 3 mo before surgery, followed by surgical pathology. The following small bowel lesions were blindly reported by one sonologist, radiologist, surgeon and histolopathologist: disease site, extent, strictures, abscesses, fistulae, small bowel dilation. Comparison between findings at SICUS, CTE, surgical specimens and histological examination was made by assessing the specificity, sensitivity and accuracy of each technique, when using surgical findings as gold standard. RESULTS: Among the 15 patients enrolled, CTE was not feasible in 2 patients, due to urgent surgery in one patients and to low compliance in the second patient, refusing to perform CTE due to the discomfort related to the naso-jejunal tube. The analysis for comparing CTE vs SICUS findings was therefore performed in 13 out of the 15 CD patients enrolled. Differently from CTE, SICUS was feasible in all the 15 patients enrolled. No complications were observed when using SICUS or CTE. Surgical pathology findings in the tested population included: small bowel stricture in 13 patients, small bowel dilation above ileal stricture in 10 patients, abdominal abscesses in 2 patients, enteric fistulae in 5 patients, lymphnodes enlargement (> 1 cm) in 7 patients and

    Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) has become an established operation for patients with ulcerative colitis and familial adenomatous polyposis (FAP). The results of a 15-year experience with IPAA are reported. Between September 1982 and June 1997, 203 patients had IPAA surgery. From a review of the charts, data were collected on the surgical procedure, the diagnosis and early and late complications. Pouch function was assessed by means of a postal questionnaire. Of the 201 patients (median age of 32 years; 89 women) with complete records, 122 had J pouches, 65 had W pouches and 14 S pouches were constructed. The pre-operative diagnosis in 88% was ulcerative colitis and in 10% it was FAP. During a median follow-up time of 6.1 years the diagnoses were changed for 8% of the patients; in 4% the diagnosis was changed to Crohn's disease. The overall mortality was 1.5% (early = 2, late = 1). The overall morbidity was 62% (early = 17%, late = 52%). The pouch was removed or was non-functional in 9%. All patients with a final diagnosis of Crohn's disease have had their pouch excised. The median stool frequency was 4.0 (range 1.3-8.7) during the day, and 0.7 (range 0-2.1) during the night. The fewer night-time stools (J = 1.0+/-0.6; W = 0.4+/-0.5 P requirement of the W-pouch patients for anti-diarrhoeals (P = 0.004) were offset by the need for two W-pouch patients to pass a catheter to empty their pouches. The type of patients who present for IPAA surgery and the outcomes observed in this series of Auckland patients are similar to those reported from major centres elsewhere.

    This experiment was conducted to determine standardized ileal amino acid digestibility (SIAAD) of commonly used feed ingredients in poultry diets in Pakistan. These feed ingredients included corn, rice broken (RB), rice polishings (RP), wheat bran (WB), sunflower meal (SFM), cottonseed meal (CSM), guar meal (GM), soybean meal (SBM) from India and Argentine and fish meal (FM). The SIAAD of each ingredient was determined in triplicate using 21-days-old broilers. Day-old male broiler chicks (Hubbard× Hubbard) were reared on corn-SBM based diet from 1 to 13 days and thereafter birds were fed experimental diets from day 14 to 21. Each diet was fed to 36 birds kept in six replicate cages, each cage had six birds. In cereals, the SIAAD of corn’s amino acid (AA) (90.1%) was similar (p>0.05) to RB (89.0%). Isoleucine (97.8%) and lysine (96.9%) were highly digestible AA in corn and RB, respectively. Among cereal-by products, WB’s SIAAD (76.9%) was same (p>0.05) as RP (71.9%). Arginine from WB (82.5%) and RP (83.2%) was highly digestible. However, threonine in WB (72.7%) and leucine in RP (69.6%) were the lowest digestible AAs. In plant protein meals, AAs from Argentine-SBM (85.1%) and Indian-SBM (83.4%) had higher (pdigestible from indispensable AAs. In SFM, methionine (91.4%) SIAAD was the greatest. The average SIAAD of FM was 77.6%. Alanine from FM had the highest (84.0%) but cysteine (62.8%) had the lowest SIAAD. In conclusion, cereals i.e. corn and RB had higher (p0.05). The SBM from plant protein meals had higher (p<0.05) SIAAD than other studied feed ingredients. However, the GM had the lowest (p<0.05) SIAAD among protein meals. PMID:26954227

    Urinary incontinence or the inability to void spontaneously after ileal orthotopic bladder substitution is a frequent finding in female patients. To evaluate how hysterectomy and nerve sparing affect functional outcomes and whether these relate to pre- and postoperative urethral pressure profile (UPP) results. Prospectively performed pre- and postoperative UPPs of 73 female patients who had undergone cystectomy and bladder substitution were correlated with postoperative voiding and continence status. Outcome analyses were performed with the Kruskal-Wallis test, Wilcoxon-Mann-Whitney, or two-group post hoc testing with the Bonferroni correction. Chi-square or Fisher exact tests were applied for the categorical data. Of postoperatively continent or hypercontinent patients, 22 of 43 (51.2%) had the uterus preserved; of incontinent patients, only 4 of 30 (13.3%, pcontinent or hypercontinent patients, 27 of 43 patients (62.8%) had bilateral and 15 of 43 (34.9%) had unilateral attempted nerve sparing. In incontinent patients, 11 of 30 (36.7%) had bilateral and 16 of 30 (53.3%) had unilateral attempted nerve sparing (p=0.02). When compared with postoperatively incontinent patients, postoperatively continent patients had a longer functional urethral length (median: 32mm vs 24mm; prest (56cm H2O vs 35cm H2O; prest (74cm H2O vs 47.5cm H2O; p=0.01). The main limitation was the limited number of patients. In female patients undergoing radical cystectomy and bladder substitution, preservation of the uterus and attempted nerve sparing results in better functional outcomes. The preoperative UPPs correlate with postoperative voiding and continence status and may predict which patients are at a higher risk of functional failure after bladder substitution. If preservation of the urethra's innervation is not possible during cystectomy, poor functional results with bladder substitutes are likely. Copyright © 2015 European Association of Urology.

    A potential complication in women after ileal pouch-anal anastomosis (IPAA) is sexual impairment and reduced fertility. The aim was to evaluate sexual function and fertility after IPAA. All female patients who underwent an IPAA between 2004 and 2013 were retrospectively included. Sexual function, fertility, and continence were explored by the female sexual function index (FSFI), telephonic interview, and Wexner's score. Among 127 women included, 93 responded to the questionnaires (73.2%). Seventy five were sexually active, and 48 (64%) had normal sexual function (FSFI > 26). In univariate analysis, there was a significant relationship between ulcerative colitis (p = 0.0161), age > 40 years (p = 0.01311), number of bowel movements (p = 0.0238), nocturnal pouch activity (p = 0.0094), use of loperamide (p = 0.0283), and existence of sexual dysfunction. After multivariate analysis, age and nocturnal pouch activity were associated with a worse sexual function (p = 0.0235, OR = 3.3 (1.2-9.9) and p = 0.0094, OR = 4.1 (1.4-13.5)). Of 16 patients who wished to have children, 10 (63%) became pregnant without recourse to in vitro fertilization, of whom 3 had two or more pregnancies. In total, there were 13 children born after IPAA. The mean time between the first pregnancy and surgery was 24.8 ± 22 months. At 12 and 24 months after cessation of contraception, 57 and 67% had at least one pregnancy. While sexual function is impaired in a limited number of patients, the impact of surgery can be regarded as modest. Age and nocturnal pouch activity were some independent factors of worse sexual function. The risk of infertility should not preclude consideration of IPAA as a treatment option.

In secondary infertility tubal occlusion was more common which accounted for 3 (30%). Conclusion: Laparoscopic procedures are less invasive, more convenient and more precise for diagnosis of sub-fertility in women. (author)

    Reduced port laparoscopic surgery has recently emerged as a method to improve the cosmetic results of conventional laparoscopic surgery. We reported our technique of reduced port laparoscopic colectomy using 3-port and short-time outcomes. Between 2005 and 2012, we performed 161 reduced port laparoscopic colectomies using the 3-port technique. Data analyzed in-cluded age, gender, body mass index (BMI), duration of surgery, number of harvested lymph nodes, and duration of hospital stay. All of the cases were successfully performed using the 3-port procedure. The median durations of surgery and postoperative hospital stay were 140 mm (range 75-463 mm) and 9 days (range 5-38 days), respectively. No mortality was associated with this technique. Reduced port laparoscopic colectomy is feasible and may have advantages over conventional laparoscopic colectomy.

    Full Text Available The establishment of gut microbiota is increasingly recognized as a crucial action in neonatal development, host health and productivity. We hypothesized that the ileal microbiome shifted as goats matured, and this colonization process would be associated with host fermentation capacity. To this end, eighteen Liuyang black grazing goats were randomly slaughtered at d 0, 7, 28, 42 and 70. Ileal microbiota was profiled by Miseq sequencing of 16S rRNA gene of bacteria, and fermentation capacity volatile fatty acid, activities of amylase, carboxymethylcellulase (CMCase and xylanase was determined using digesta sample. Principal coordinate analysis (PCoA revealed that each age group harboured its distinct bacteria. Total bacteria copy number and most alpha diversity indexes increased (P < 0.01 from d 0 to 70. At the phylum level, abundances of Cyanobacteria (P = 0.018 and TM7 (P = 0.010 increased linearly, abundances of Bacteroidetes (P = 0.075 and Fibrobacteres (P = 0.076 tended to increase linearly, whist Proteobacteria abundance tended to decline quadratically (P = 0.052 with age. At the genus level, Enterococcus (30.9%, Lactobacillus (32.8% and Escherichia (2.0% dominated at d 0, while Prevotella, Butyrivibrio, Ruminococcus, SMB53 and Fibrobacter surged in abundance after d 20. The highest amylase activity was observed at d 42, while xylanase activity increased quadratically (P = 0.002 from d 28 to 70. Correlation analysis indicated that abundances of Bacteroides, Clostridium, Lactobacillus, Propionibacterium, Enterococcus and p-75-a5 positively correlated with enzyme activity. Collectively, ileal bacteria in grazing goats assemble into distinct communities throughout development, and might participate in the improvement of host fermentation capacity.

  20. Estimation of the endogenous N proportions in ileal digesta and faeces in 15N-labelled pigs

    4 castrated male pigs 40 kg fitted with simple 'T' cannulas in the terminal ileum were given 15 N-labelled ammonium salts, added to a low protein diet, for 6 days. Excretion of 15 N in urine and feces was monitored daily throughout the labelling and subsequent experimental periods. During the experimental period the pigs were given a diet based on wheat and fish meal, supplemented with varying levels of partially hydrolyzed straw meal to give crude fiber contents ranging from 40 to 132 g/kg. After adaptation to the particular levels of straw meal, feces and ileal digesta were collected during successive 24 h periods. N digestibility values were determined by the chromium oxide ratio method. The retention of 15 N-labelled non-specific N was 0.46 of the dose given. The validity of using urine values as a measure of 15 N abundance in endogenous N was demonstrated by the similarity of 15 N abundance in urine immediately before slaughter at the end of the experiment and in the digestive secretory organs thereafter. The average amount of endogenous N passing the terminal ileum was 3.4 g/day or 0.30-0.50 of total ileal N flow. This was not affected by dietary fiber level. The proportion of fecal N which was of endogenous origin was similar to that in ileal digesta, suggesting similar utilization of endogenous and residual dietary N by hindgut bacteria. Half the endogenous N entering the large intestine was reabsorbed there. Increasing dietary crude fiber from 40 to 132 g/kg increased fecal endogenous N excretion from 1.3 to 2.0 g/animal and day.

    The aim of this study is to estimate the overall rates of significant incontinent conduit-related complications and compare rates between conduit types. This was a retrospective review of 166 patients who underwent incontinent urinary diversion from April 1993 through April 2013. Patients were categorized by conduit type-ileal, sigmoid colon, and transverse colon. Significant conduit-related complications were assessed at 30 and 90days after surgery. Significant conduit-related complication was defined as any of the following: ureteral stricture, conduit leak, conduit obstruction, conduit ischemia, ureteral anastomotic leak, stent obstruction requiring intervention via interventional radiology procedure or reoperation, and renal failure. A total of 166 patients underwent formation of an incontinent urinary conduit, most commonly during exenteration for gynecologic malignancy. There were 129 ileal, 11 transverse colon, and 26 sigmoid conduits. The overall significant conduit-related complication rate within 30days was 15.1%. Complication rates for ileal, transverse and sigmoid conduits were 14.7%, 0%, and 23.1%, respectively (Fisher's exact test, p=0.24). By 90days, the Kaplan-Meier estimated rates of significant complications were 21.8% overall, and 22.3%, 0%, and 28.9%, respectively, by conduit type (log-rank test, p=0.19). The most common significant conduit-related complications were conduit or ureteral anastomotic leaks and conduit obstructions. By 1 and 2years following surgery, the Kaplan-Meier estimated overall rate of significant conduit-related complication increased to 26.5% and 30.1%, respectively. Our study suggests that there are multiple appropriate tissue sites for use in incontinent conduit formation, and surgical approach should be individualized. Most significant conduit-related complications occur within 90days after surgery. Copyright © 2014 Elsevier Inc. All rights reserved.

    The retrograde axonal transport of intravenously (i.v.) administered 125 I-nerve growth factor ( 125 I-NGF) was examined in mesenteric nerves innervating the small bowel of rats with streptozocin (STZ) diabetes using methods described in detail in the companion article. The accumulation of 125 I-NGF distal to a ligature on the ileal mesenteric nerves of diabetic animals was 30-40% less than in control animals. The inhibition of accumulation of 125 I-NGF in diabetic animals was greater at a ligature tied 2 h after i.v. administration than at a ligature tied after 14 h, which suggests that the diabetic animals may have a lag in initiation of NGF transport in the terminal axon or retardation of transport at some site along the axon. The 125 I-NGF transport defect was observed as early as 3 days after the induction of diabetes, a time before the development of structural axonal lesions, and did not worsen at later times when dystrophic axonopathy is present. Both the ileal mesenteric nerves, which eventually develop dystrophic axonopathy in experimental diabetes, and the jejunal mesenteric nerves, which never develop comparable structural alterations, showed similar 125 I-NGF transport deficits, suggesting that the existence of the transport abnormality does not predict the eventual development of dystrophic axonal lesions. Autoradiographic localization of 125 I-NGF in the ileal mesenteric nerves of animals that had been diabetic for 11-13 mo demonstrated decreased amounts of 125 I-NGF in transit in unligated paravascular nerve fascicles. There was, however, no evidence for focal retardation of transported 125 I-NGF at the sites of dystrophic axonal lesions

    Two experiments using soybean meal (SBM) or canola meal (CM) were conducted to investigate whether the choice of digestibility marker influenced the apparent ileal digestibility (AID) or standardized ileal digestibility (SID) of N and AA in diets supplemented with phytase. In each experiment, 18 barrows fitted with T-cannulas at the ileocecal junction were assigned to 3 diets consisting of a N-free diet to determine endogenous losses of N and AA, a semipurified diet (SBM in Exp. 1 or CM in Exp. 2), and the semipurified diet supplemented with phytase at 1,000 phytase units/kg. Three digestibility markers including acid-insoluble ash (AIA), chromic oxide (Cr2O3), and titanium dioxide (TiO2) were added to each diet at 3 g/kg. Each diet was fed for 7 d, consisting of a 5-d adjustment and a 2-d collection of ileal digesta. In both studies, basal ileal endogenous losses determined with Cr2O3 as a digestibility marker were lower (Pdigestibility markers. Using SBM as the protein source in Exp. 1, there was no interaction between phytase and digestibility marker on AID or SID of AA. The AID of N and AA in SBM using AIA as a digestibility marker tended to be lower (Pdigestibility markers. Phytase supplementation increased (Pdigestibility marker tended to be associated with lower (Pdigestibility marker and phytase. Phytase supplementation had effects (Pdigestibility marker. With Cr2O3 or TiO2 as the digestibility marker in the CM diets, phytase supplementation increased (Pdigestibility marker. In contrast, there were no clear improvements in AA digestibility from phytase supplementation for SBM. Phytase effects on AID or SID of AA were dependent on the digestibility marker used in diets when CM was used as the protein source but not when SBM was used as the protein source. Therefore, AA digestibility response to phytase supplementation may depend on the protein being evaluated as well as the choice of digestibility marker.

    An isotope dose technique was utilized (i) to determine endogenous amino acid (AA) and protein losses and (ii) to propose adjusted values for AA requirements. The endogenous flow rate was calculated from the pool of enrichment in plasma AA, assuming similitude to enrichment of endogenous AA. In experiment 1, chicks were orally administered D4-lysine at 2% of estimated lysine intake from 16 to 24 days to find the isotopic steady state of the atom percent excess (APE) of lysine for plasma and jejunal and ileal digesta. The APE of D4-lysine in plasma, jejunal digesta and ileal digesta reached the isotopic steady state at 5.5, 3.4 and 2.0 days, respectively, by using the broken-line model. It was assumed that the isotopic steady state at 5 days identified for D4-lysine is also representative for the 15N-labeled AA. In experiment 2, chicks were fed diets from 1 to 21 days with increasing levels of fat (6%, 8%, 12%, 13% extract ether), protein (26%, 28.5%, 31% CP) or fiber (14%, 16%, 18% NDF) by adding poultry fat, soybean meal, blended animal protein or barley. Chicks were orally administered 15N-threonine, 15N-cysteine, 15N-methionine, 15N-lysine and 15N-leucine at 2% of estimated daily intake for 5 days from 17 to 21 days of age. Dietary nutrients influenced endogenous losses (EL), where dietary fat stimulated EL of lysine (P=0.06), leucine and protein (P=0.07); dietary protein enhanced EL of leucine and protein; and finally the dietary fiber increased EL of leucine. Dietary nutrients also affected apparent ileal digestibility (AID). Dietary fat increased AID of cysteine but decreased AID of lysine. Dietary protein reduced AID of protein, threonine, lysine and leucine, and similarly dietary fiber decreased AID of protein, threonine, methionine, lysine and leucine. In contrast, dietary fat or protein did not affect real ileal digestibility (RID) of protein and AA except threonine and leucine. The dietary fiber reduced the RID of protein, threonine and leucine.

    Full Text Available Myasthenia gravis is a chronic autoimmune disease affecting voluntary skeletal muscles. The altered sensitivity of acetylcholine receptors to muscle relaxants and concomitant treatment with anticholinesterase in these patients affect their anaesthetic management. Patients who have undergone bowel anastomosis and are on regular anticholinesterase treatment are susceptible to anastomotic leaks. We report successful anaesthetic management of class I myasthenic patient with coexisting small bowel intussusception operated for jejuno-ileal anastomoses using regional, inhalational and intravenous (i.v anaesthesia based on train of four responses, and avoiding the use of reversal (anticholinesterase.

    Current diagnostic tests for Johne's disease (JD), a chronic granulomatous inflammation of the gastrointestinal tract of ruminants caused by Mycobacterium avium subspecies paratuberculosis (MAP), lack the sensitivity to identify infected animals at early (asymptomatic) stages of the disease. The objective was to determine the pattern of MAP-associated dysbiosis of intestinal microbiota as a potential biomarker for early detection of infected cattle. To that end, genomic DNA was extracted from ileal mucosa and fecal samples collected from 28 MAP-positive and five control calves. High-throughput Illumina sequencing of the V4 hypervariable region of the 16S rRNA gene was used for community profiling of ileal mucosa-associated (MAM) or fecal microbiota. The PERMANOVA analysis of unweighted UniFrac distances revealed distinct clustering of ileal MAM (P = 0.049) and fecal microbiota (P = 0.068) in MAP-infected vs. control cattle. Microbiota profile of MAP-infected animals was further investigated by linear discriminant analysis effective size (LEfSe); several bacterial taxa within the phylum Proteobacteria were overrepresented in ileal MAM of control calves. Moreover, based on reconstructed metagenomes (PICRUSt) of ileal MAM, functional pathways associated with MAP infection were inferred. Enrichment of lysine and histidine metabolism pathways, and underrepresentation of glutathione metabolism and leucine and isoleucine degradation pathways in MAP-infected calves suggested potential contributions of ileal MAM in development of intestinal inflammation. Finally, simultaneous overrepresentation of families Planococcaceae and Paraprevotellaceae, as well as underrepresentation of genera Faecalibacterium and Akkermansia in the fecal microbiota of infected cattle, served as potential biomarker for identifying infected cattle during subclinical stages of JD. Collectively, based on compositional and functional shifts in intestinal microbiota of infected cattle, we inferred that

    Full Text Available Rationale and Objectives: Various devices are used to aid in the education of laparoscopic skills ranging from simple box trainers to sophisticated virtual reality trainers. Virtual reality system is an advanced and effective training method, however it is yet to be adopted in India due to its cost and the advanced technology required for it. Therefore, box trainers are being used to train laparoscopic skills. Hence this study was undertaken to assess the overall effectiveness of the box-training course. Study Procedure: The study was conducted during six-day laparoscopic skills training workshops held during 2006. Twenty five surgeons; age range of 26 to 45 years, of either sex, who had not performed laparoscopic surgery before; attending the workshop were evaluated. Each participant was given a list of tasks to perform before beginning the box-training course on day one and was evaluated quantitatively by rating the successful completion of each test. Evaluation began when the subject placed the first tool into the cannula and ended with task completion. Two evaluation methods used to score the subject, including a global rating scale and a task-specific checklist. After the subject completed all sessions of the workshop, they were asked to perform the same tasks and were evaluated in the same manner. For each task completed by the subjects, the difference in the scores between the second and first runs were calculated and interpreted as an improvement as a percentage of the initial score. Statistical Analysis: Wilcoxon matched-paired signed-ranks test was applied to find out the statistical significance of the results obtained. Results: The mean percentage improvement in scores for both the tasks, using global rating scale, was 44.5% + 6.930 (Mean + SD. For task 1, using the global rating scale mean percentage improvement was 49.4% + 7.948 (Mean + SD. For task 2, mean percentage improvement using global rating scale was 39.6% + 10.4 (Mean

    Full Text Available Laparoscopic fundoplication is fast emerging as the treatment of choice of gastro-esophageal reflux disease. However, a complication peculiar to laparoscopic surgery for this disease is the intrathoracic migration of the wrap. This article describes a case of a male patient who developed this particular complication after laparoscopic total fundoplication. Following a trauma, wrap migration occurred. The typical history and symptomatology is described. The classical Barium swallow picture is enclosed. Laparoscopic redo fundoplication was carried out. The difficulties encountered are described. Postoperative wrap migration can be suspected clinically by the presence of a precipitating event and typical symptomatology. Confirmation is by a Barium swallow. Treatment is by redo surgery.

    In this case report, we discuss single-incision laparoscopic cecectomy for low-grade appendiceal neoplasm after laparoscopic anterior resection for rectal cancer. The optimal surgical therapy for low-grade appendiceal neoplasm is controversial; currently, the options include appendectomy, cecectomy, right hemicolectomy, and open or laparoscopic surgery. Due to the risk of pseudomyxoma peritonei, complete resection without rupture is necessary. We have encountered 5 cases of low-grade appendiceal neoplasm and all 5 patients had no lymph node metastasis. We chose the appendectomy or cecectomy without lymph node dissection if preoperative imaging studies did not suspect malignancy. In the present case, we performed cecectomy without lymph node dissection by single-incision laparoscopic surgery (SILS), which is reported to be a reduced port surgery associated with decreased invasiveness and patient stress compared with conventional laparoscopic surgery. We are confident that SILS is a feasible alternative to traditional surgical procedures for borderline tumors, such as low-grade appendiceal neoplasms. PMID:24868331

    Full Text Available The wide use of current diagnostic techniques, such as ultrasound study, computed tomography, and magnetic resonance imaging, has led to significantly increased detection rates for disease in its early stages. This gave rise to a change in the standards for the treatment of locally advanced renal cell carcinoma (RCC. Laparoscopic nephrectomy (LN has recently become the standard treatment of locally advanced RCC in the clinics having much experience with laparoscopic surgery. The chief drawback of LN is difficulties in maintaining intraoperative hemostasis and a need for creating renal tissue ischemia. The paper gives the intermediate results of application of the new procedure of LN using radiofrequency thermal ablation in patients with non-ischemic early-stage RCC.

    Full Text Available Since its introduction at the end of the 20th century, laparoscopic cholecystectomy has evolved into a safe and convenient minimally invasive surgical method, which is now the gold standard therapy for cholelithiasis worldwide. Physicians have continued to improve upon the procedure, creating methods that further minimize the related scarring and pain, such as the laproendoscopic single-site cholecystectomy and the gasless-lift laparoscopy. Additionally, the primary challenge of limited operative space in these procedures remains a key feature requiring improvement. In this review, the development and progression of laparoscopic cholecystectomy over the past 26 years is discussed, highlighting the current advantages and disadvantages that need to be addressed by practicing physicians to maximize the clinical value of this important therapy.

    Peptic ulcer is a common disease affecting millions of people every year. Despite improved understanding and treatment of the disease, the number of patients admitted with duodenal peptic ulcer perforation has not decreased. Deaths from peptic ulcer disease overcome other common emergency situations. Laparoscopic repair of the perforated peptic ulcer (PPU) is the gold standard approach for simple perforation. However, in patients with large perforated chronic ulcers laparotomy with pyloroplasty is the standard treatment. It is generally accepted to perform open surgery in PPU emergencies because of the greater knowledge and experience gathered over the past decades and less potential harm for the patient or surgical complications. We present a case of successful laparoscopic pyloroplasty of a perforated duodenal ulcer with stenosis.

    Laparoscopic nephrectomy is gaining popularity. Improved instrumentation is making surgery easier with fewer complications. Our first three laparoscopic nephrectomies using the Harmonic Scalpel were performed on two women and one man. The surgical indications were nonfunctioning kidneys (two left, one right) with hypertension in one patient and stone disease in two. The three patients had a mean age of 46.3 years. The average hospital stay was 4 days, the average operative time 3.7 hours, and the average blood loss 160 mL. No complications occurred. Patients resumed oral intake within 8 hours postoperatively. We found the Harmonic Scalpel easy and safe to use. It saved time, was cost effective, and was capable of easily controlling small-vessel bleeding. In conclusion, the Harmonic Scalpel could be used effectively for both dissection and bleeding control without suction or other instrumentation.

  18. Carbon Dioxide Embolism during Laparoscopic Surgery

    2012-01-01

    Clinically significant carbon dioxide embolism is a rare but potentially fatal complication of anesthesia administered during laparoscopic surgery. Its most common cause is inadvertent injection of carbon dioxide into a large vein, artery or solid organ. This error usually occurs during or shortly after insufflation of carbon dioxide into the body cavity, but may result from direct intravascular insufflation of carbon dioxide during surgery. Clinical presentation of carbon dioxide embolism ranges from asymptomatic to neurologic injury, cardiovascular collapse or even death, which is dependent on the rate and volume of carbon dioxide entrapment and the patient's condition. We reviewed extensive literature regarding carbon dioxide embolism in detail and set out to describe the complication from background to treatment. We hope that the present work will improve our understanding of carbon dioxide embolism during laparoscopic surgery. PMID:22476987

    Abstract Gallbladder rupture due to blunt abdominal injury is rare. There are few reports of traumatic gallbladder injury, and it is commonly associated with other concomitant visceral injuries. Therefore, it is difficult to diagnose traumatic gallbladder rupture preoperatively when it is caused by blunt abdominal injury. We report a patient who underwent laparoscopic cholecystectomy after an exact preoperative diagnosis of traumatic gallbladder rupture. A 43-year-old man was admitted to our hospital due to blunt abdominal trauma. The day after admission, abdominal pain and ascites increased and a muscular defense sign appeared. Percutaneous drainage of the ascites was performed, and the aspirated fluid was bloody and almost pure bile. He was diagnosed with gallbladder rupture by the cholangiography using the endoscopic retrograde cholangiopancreatography technique. Laparoscopic cholecystectomy was performed safely, and he promptly recovered. If accumulated fluids contain bile, endoscopic cholangiography is useful not only to diagnose gallbladder injury but also to determine the therapeutic strategy. PMID:27462188

    2001-01-01

    We report seven patients in whom five dropped surgical clips and two gallstones were visualized in the peritoneal cavity, on radiological studies. In two, subphrenic abscesses and empyemas developed as a result of dropped clips into the peritoneal cavity during or following laparoscopic cholecystectomy. In one of these two, a clip was removed surgically from the site of an abscess. In two other patients dropped gallstones, and in three, dropped clips led to no complications. These were seen incidentally on studies done for other indications. Abdominal abscess secondary to dropped gallstones is a well-recognized complication of laparoscopic cholecystectomy (LC). We conclude that even though dropped surgical clips usually do not cause problems, they should be considered as a risk additional to other well-known causes of post-LC abdominal sepsis

    2018-02-01

    Laparoscopy was a progressive step to advancing surgical procedures as it minimised the scars left on the body after surgery, compared to traditional open surgery. Many years later, single-incision laparoscopic surgery (SILS) was created where, instead of having multiple incisions, only one incision is made or multiple small incisions in one location. SILS, or laparoendoscopic single-site surgery (LESS), may produce lesser scars but drawbacks for the surgeons are still present. This paper aims to present related literature of the recent technological developments in laparoscopic tools and procedure particularly in the vision system, handheld instruments. Tech advances in LESS will also be shown. Furthermore, this review intends to give an update on what has been going on in the surgical robot market and state which companies are interested and are developing robotic systems for commercial use to challenge Intuitive Surgical's da Vinci Surgical System that currently dominates the market.

    Haemangiomas are the most common solitary benign neoplasm of the liver with an incidence ranging from 5% to 20%. Although usually small and asymptomatic, they may reach considerable proportions and rarely give rise to life-threatening complications. Surgical intervention is required for incapacitating symptoms, established complications, and diagnostic uncertainty. The resection of haemangiomas demands meticulous surgical technique, owing to their high vascularity and the concomitant risk of intra-operative haemorrhage. Laparoscopic resection of giant haemangiomas is even more challenging, and has only been reported twice. We here report the case of a giant 10 cm liver haemangioma which was successfully resected laparoscopically using the laparoscopic HabibTM 4×, a bipolar radiofrequency device, without clamping major vessels and with minimal blood loss. Transfusion of blood or blood products was not required. The patient had an uneventful recovery and was asymptomatic at 7-mo follow-up.

    This study was performed to evaluate short-term clinical outcomes of laparoscopic intracorporeal ileocolic anastomosis following resection of the right colon. This was a retrospective study of selected patients who underwent laparoscopic intracorporeal ileocolic anastomosis following resection of the right colon for tumors or Crohn's disease by a single surgeon from July 2002 through June 2012. Data were retrieved from an Institutional Review Board-approved database. Study end point was postoperative adverse events, including mortality, complications, reoperations, and readmissions at 30 days. Antiperistaltic side-to-side anastomoses were fashioned laparoscopically with a 60-mm-long stapler cartridge and enterocolotomy was hand-sewn intracorporeally in two layers. Values were expressed as medians (ranges) for continuous variables. There were 243 patients (143 females) aged 61 (range = 19-96) years, with body mass index of 29 (18-43) kg/m(2) and ASA 1:2:3:4 of 52:110:77:4; 30 % had previous abdominal surgery and 38 % had a preexisting comorbidity. There were 84 ileocolic resections with ileo ascending anastomosis and 159 right colectomies with ileotransverse anastomosis. Operating time was 135 (60-220) min. Estimated blood loss was 50 (10-600) ml. Specimen extraction site incision length was 4.1 (3-4.4) cm. Conversion rate was 3 % and there was no mortality at 30 days, 15 complications (6.2 %), and 8 reoperations (3.3 %). Readmission rate was 8.7 %. Length of stay was 4 (2-32) days. Pathology confirmed Crohn's disease in 84 patients, adenocarcinoma in 152, and other tumors in 7 patients. Laparoscopic intracorporeal ileocolic anastomosis following resection of the right colon resulted in a favorable outcome in selected patients with Crohn's disease or tumors of the right colon.

    Full Text Available Purpose: The purpose of the study was two-fold. Firstly it was to assess the suitability for tubal recanalization and factors predicting successful laparoscopic recanalization. Secondly, it was to analyze the fertility outcomes and factors affecting the pregnancy rate following laparoscopic tubal recanalization. Materials and Methods: A retrospective chart review of prospectively followed-up 29 women at a tertiary care center seeking tubal sterilization reversal between May 2005 and February 2010 were included. Results: In 14 (48.3% women unilateral tubes were suitable and in only 3 women (10.3% bilateral tubes were suitable. All cases with laparoscopic tubal sterilization were suitable, whereas all cases with fimbriectomy were unsuitable for recanalization. In 6 (20.7% cases salphingostomy was performed as an alternative procedure to tubal reanastomosis. The overall pregnancy rate was 58.8%. In cases with sterilization by Pomeroy′s method, 4 out of 10 (40% conceived, whereas for laparoscopic tubal ligation cases 6 out of 7 (85.7% conceived (P=0.32. None of the patients with final tubal length <5 cm conceived (P=0.03. Comparing the age at recanalization, in women ≤30 years, 71.4% conceived, as compared with 50% when age of women was more than 30 years (P=0.37. Conclusions: The important factors determining the success of recanalization are technique of sterilization and the remaining length of the tube after recanalization. The gynecologist must use an effective technique of sterilization to minimize the failure rates, but at the same time, which causes minimal trauma, and aim at preserving the length of the tube so that reversal is more likely to be successful, should the patient′s circumstances change.

The aim of the present paper is to review current evidence and well-established practice for elective laparoscopic perioperative management. There is no firm evidence for best anesthetic technique, further high quality studies assessing short as well as more protracted outcomes are needed. Preventive multi-modal analgesia, combining non-opioid analgesics, paracetamol, nonsteroidal anti-inflammatory drugs or coxib, and local anesthesia, has a long history. Local anesthesia improves postoperative pain and facilitates discharge on the day of surgery. Whether transversus abdominis plane-block has clinically important advantages compared to local infiltration analgesia needs further studies. Single intravenous dose steroid, dexamethasone, reduces postoperative nausea and vomiting, pain, and enhances the recovery process. Multi-modal analgesia is reassuringly safe thus having a positive benefit versus risk profile. Adherence to modern guidelines avoiding prolonged fasting and liberal intravenous fluid regime supports rapid recovery. The effects of CO2 insufflation must be acknowledged and low intra-abdominal pressure should be sought in order to reduce negative cardiovascular/respiratory effects. There is no firm evidence supporting heating and humidification of the insufflated gas. The potential risk for CO2/gas entrainment into vasaculture, gas emboli, or subcutaneous/intra-thoracic into the pleural space must be kept in mind. Laparoscopic cholecystectomy in ASA 1-2 patients following a multi-modal enhanced recovery protocol promotes high success rate for discharge on the day of surgery. Keywords: laparoscopic

    Large inter-individual variation in the composition of the intestinal microbiota between unrelated individuals has made it challenging to identify specific aspects of dysbiosis that lead to Crohn's disease. To reduce variations in exposure during establishment of the gut flora and influence of genotype, we studied the mucosaassociated microbiota of monozygotic twin pairs that were discordant (n=6) or concordant (n=4) for Crohn's disease. DNA was extracted from biopsies collected from 5 locations between the ileum and rectum. Bacterial 16S ribosomal RNA genes were amplified and community composition assessed by terminal-restriction fragment length polymorphism, cloning and sequencing and quantitative real-time PCR. The microbial compositions at all biopsy locations for each individual were similar, regardless of disease state, but there were differences between individuals. In particular, individuals with predominantly ileal Crohn's had a dramatically lower abundance (P<0.001) of Faecalibacterium prausnitzii and increased abundance (P<0.03) of Escherichia coli compared to healthy co-twins and those with Crohn's localized in the colon. This dysbiosis was significantly correlated to the disease phenotype rather than genotype. The reduced abundance of F. prausnitzii and increased abundance of E. coli are indicative of an ileal Crohn's disease phenotype, distinct from colonic Crohn's disease and the relative abundances of these specific bacterial populations are promising biomarker candidates for differential diagnosis of Crohn's and eventually customized treatment.

    This study was conducted to determine the chemical composition and standardized ileal digestibility coefficients (SID) of crude protein (CP) and amino acids (AA) of European soya bean and rapeseed products in pigs. Six soya bean and two rapeseed products were used as the sole dietary source of CP and AA, including raw (FFSB) and roasted full-fat soya beans (FFSB R oasted ), soya bean (SBC) and rapeseed cake (RSC), and rapeseed meal (RSM) from Bavaria (Germany), soya bean meal (SBM) from the Danube region (Austria; SBM A ustria ), a commercially available standard SBM (SBM S td ) and an imported genetically modified organism-free SBM (SBM GMO -free ). Eight ileal- cannulated pigs with an initial body weight of 32 ± 2 kg were allotted to a row-column design with eight diets and six periods of seven days each. Trypsin inhibitor activity (TIA) ranged from 1.8 in SBM S td to 24.5 mg/g DM in FFSB. The SID of CP and all AA in FFSB R oasted were greater than in FFSB, but lower when compared to SBC and SBM A ustria (p soya bean and rapeseed products as influenced by differences in processing conditions.

    Apparent ileal digestibility (AID) of diets containing sesame expeller (SE) and soya bean meal (SBM) was determined using 15 piglets (Genetiporc(®)), weaned at 17 ± 0.4 days with average body weight of 6.4 ± 0.7 kg (Fertilis 20 × G Performance, Genetiporc(®), PIC México, Querétaro, México). Piglets were randomly assigned to three treatments: (i) a reference diet with casein as the sole protein source; (ii) a mixed diet of casein-SE; and (iii) a mixed diet of casein-SBM. The chemical composition of SE and SBM was determined, and AID and standardized ileal digestibility (SID) of crude protein (CP) and amino acids (AAs) were determined for each protein source. SE contained greater quantities of ether extract, neutral detergent fibre, phytic acid, methionine and arginine than SBM. Lysine and proline contents and trypsin inhibitor activity were higher in SBM than in SE. The AID and SID of CP and AA (except for lysine and proline) were similar in SE and SBM. The AID of lysine and proline was higher in SBM than in SE (p < 0.05), and the SID of proline was higher in SE than in SBM (p < 0.05). These findings indicate that SE is an appropriate alternative protein source for early weaned pigs. Journal of Animal Physiology and Animal Nutrition © 2014 Blackwell Verlag GmbH.

    Selenium-75 homocholic acid conjugated with taurine ({sup 75}Se-HCAT) was used during loperamide administration in seven patients suspected of having bile acid malabsorption due to late radiation damage and small-bowel resection in order to document the aetiology of ileal dysfunction and to adjust therapeutic mamagement. In two patients with ileal resection up to 50 cm and in one patient without resection, a reduction of bowel motility by loperamide resulted in marked normalization of the {sup 75}Se-HCAT retention measurements. Sequential scintigraphic {sup 75}Se-HCAT imaging demonstrated a significant improvement in the {sup 75}Se-HCAT reabsorption and recirculation, accompanied in one case by prolongation of colonic retention of the radiopharmaceutical. In four patients with more than 80 cm resection, the {sup 75}Se-HCAT test was abnormal during loperamide administration. In two of these patients for whom baseline values were available, no improvement in the pattern of {sup 75}Se-HCAT absorption was observed. In conclusion, the first results of loperamide {sup 75}Se-HCAT in patients suspected of having bile acid malabsorption and abnormal baseline {sup 75}Se-HCAT are promising. Intervention with loperamide is easy and seems to improve the clinical value of the test with direct therapeutic implications. Sequential {sup 75}Se-HCAT imaging is essential for interpreting changes in the {sup 75}Se-HCAT retention measurements. (orig.).

    1. Studies were conducted with tall oil fatty acids (TOFA) to determine their effect on broiler chicken performance and ileal microbiota. TOFA, a product originating from coniferous trees and recovered by fractional distillation of side-streams from pulp production, mainly comprises free long-chain fatty acids (~90%) and resin acids (~8%). Conjugated linolenic acids and pinolenic acid are characteristic fatty acid components of TOFA. 2. TOFA products at 750 mg/kg feed were tested in two 35-day broiler chicken trials, each using a wheat soya-based diet and with 12 replicate pens per treatment. In both trials, TOFA improved body weight gain at all time points (P TOFA formulations (silica carrier and palm oil coating) were tested and showed performance effects similar to liquid TOFA. 3. Ileal digesta of the broiler chickens was analysed for total eubacteria, Lactobacillus spp., Enterococcus spp., Escherichia coli and Clostridium perfringens on days 14 and 35. TOFA significantly increased total eubacteria and lactobacilli density on day 14 (P TOFA (P 250 mg/l. The in vitro results were thus in line with in vivo observations. 5. The mechanisms behind the bacterial shifts and their role in performance improvement are unknown. Further purification of TOFA components is needed to identify the effective agents.

  16. Recurrent Lower Gastrointestinal Bleeding: Ileal GIST Diagnosed by Video Capsule Endoscopy—A Case Report and Literature Review

    Full Text Available Introduction. Gastrointestinal stromal tumor (GIST in the ileum is an extremely rare cause of recurrent lower gastrointestinal bleeding (GIB. Case Report. An 89-year-old man was admitted with melana. He had extensive PMH of CAD post-CABG/AICD, AAA repair, chronic anemia, myelodysplastic syndrome, lung cancer after resection, and recurrent GIB. Prior EGDs, colonoscopies, and upper device-assisted enteroscopy showed duodenal ulcer, A-V malformation s/p cauterization, and angioectasia. On admission, Hb was 6.0 g/dL. An endoscopic capsule study showed an ulcerated tumor in the ileum. CT showed no distant metastasis. The lesion was resected successfully and confirmed as a high-grade GIST. The patient was discharged with no further bleeding. Discussion. Early diagnosis for patients with ileal GIST is often challenging. Video capsule endoscopy and double balloon enteroscopy could be useful diagnostic tools. Surgical removal is the first line for a resectable GIST. Imatinib has become the standard therapy. Conclusion. This is a unique case of an ileal GIST in a patient with recurrent GIB which was diagnosed by video capsule. Complicated medical comorbidities often lead to a significant delay in diagnosis. Therefore, we recommend that if GIB does not resolve after appropriate treatments for known causes, the alternative diagnosis for occult GIB must be considered, including malignancy such as GIST.

    Video games are mainly considered to be of entertainment value in our society. Laparoscopic surgery and video games are activities similarly requiring eye-hand and visual-spatial skills. Previous studies have not conclusively shown a positive correlation between video game experience and improved ability to accomplish visual-spatial tasks in laparoscopic surgery. This study was an attempt to investigate this relationship. The aim of the study was to investigate whether previous video gaming experience affects the baseline performance on a laparoscopic simulator trainer. Newly qualified medical officers with minimal experience in laparoscopic surgery were invited to participate in the study and assigned to the following groups: gamers (n = 20) and non-gamers (n = 20). Analysis included participants' demographic data and baseline video gaming experience. Laparoscopic skills were assessed using a laparoscopic simulator trainer. There were no significant demographic differences between the two groups. Each participant performed three laparoscopic tasks and mean scores between the two groups were compared. The gamer group had statistically significant better results in maintaining the laparoscopic camera horizon ± 15° (p value = 0.009), in the complex ball manipulation accuracy rates (p value = 0.024) and completed the complex laparoscopic simulator task in a significantly shorter time period (p value = 0.001). Although prior video gaming experience correlated with better results, there were no significant differences for camera accuracy rates (p value = 0.074) and in a two-handed laparoscopic exercise task accuracy rates (p value = 0.092). The results show that previous video-gaming experience improved the baseline performance in laparoscopic simulator skills. Copyright © 2017 IJS Publishing Group Ltd. Published by Elsevier Ltd.

    Owing to the possibility of weight regain after the long-term follow-up of gastric bypass patients and because of the high morbidity of biliopancreatic diversion with duodenal switch, single-anastomosis duodeno-ileal switch (SADIS) has emerged as a rescue procedure in bariatric surgery. The purpose of this review is to summarize the literature data on SADIS. University Hospital, NY. A comprehensive literature review was performed through October 2016 to identify English studies on SADIS performed in human subjects. Outcomes of interest were technical considerations, postoperative complications, weight loss outcome, comorbidity resolution rate, and nutritional deficiency after SADIS. A total of 12 studies including 581 SADIS patients (217 males and 364 females) were included. SADIS was a primary procedure in 508 patients (87.4%) and a conversion procedure in 73 patients (12.6%). The length of common limb was 300 cm in 54.2%, 250 cm in 23%, and 200 cm in 13.4% of patients. Anastomosis technique was a linear stapler in 26.7% and a hand sewn suture technique in 73.3% of patients. Diarrhea was the most common complication (1.2%). The average %EWL was 30% at 3 months, 55% at 6 months, 70% at 1 year, and 85% at 2 years. Co-morbidity resolution rate was 74.1% for type 2 diabetes mellitus, 96.3% for hypertension, 68.3% for dyslipidemia, 63.3% for obstructive sleep apnea, and 87.5% for GERD. Overall, vitamin A, selenium, and iron deficiency were the most common nutritional deficiencies with the possibility of the protein malnutrition in up to 34% of the patients when measured. As a modified bariatric procedure, SADIS has promising outcomes for weight loss and comorbidity resolution in morbidly obese patients. When measured, there was a high prevalence of macro-nutrient deficiencies following SADIS. There is a high technical variability, and long-term data are required before any meaningful conclusion can be made.

    Esophageal achalasia is the most common primary esophageal motor disorder. Laparoscopic Heller's myotomy combined with fundoplication represents the treatment of choice for this disease, achieving good results in about 90% of patients. However, about 10% of treated patients refer persistent or recurrent dysphagia. Many Authors showed that this failure rate is related to inadequate myotomy. To verify, from experimental to clinical study, the modifications induced by Heller's myotomy of the esophago- gastric junction on LES pressure (LES-P profile, using a computerized manometric system. From 2002 to 2010 105 patients with achalasia underwent laparoscopic calibrated Heller myotomy followed by antireflux surgery. The calibrated Heller myotomy was extended for at least 2.5 cm on the esophagus and for 3 cm on the gastric side. Each step was evaluated by intraoperative manometry. Moreover, intraoperative manometry and endoscopy were used to calibrate the fundoplication. The preoperative mean LES-P was 37.73 ± 12.21. After esophageal and gastric myotomy the mean pressure drop was 21.3% and 91.9%, respectively. No mortality was reported. Laparoscopic calibrated Heller myotomy with fundoplication achieves a good outcome in the surgical treatment of achalasia. The use of intraoperative manometry enables an adequate calibration of myotomy, being effective in the evaluation of the complete pressure drop, avoiding too long esophageal myotomy and, especially, too short gastric myotomy, that may be the cause of surgical failure.

    Although laparoscopy has become the standard approach in other procedures, this technique is not generally accepted for acute appendicitis, especially if it is complicated due reports on the increase in intra-abdominal abscesses. The purpose of this study was to evaluate the morbidity in a group of patients diagnosed with complicated apendicitis (gangrenous or perforated) who had undergone open or laparoscopic appendectomy. We prospectively studied 107 patients who had undergone appendectomy for complicated appendicitis over a two year period. Mean operation time, mean hospital stay and morbidity, such as wound infection and intra-abdominal abscess were evaluated. In the group with gangrenous appendicitis morbidity was significantly lower in laparoscopic appendectomy group (p = 0.014). Wound infection was significantly higher in the open appendectomy group (p = 0.041), and there were no significant differences in intra-abdominal abscesses (p = 0.471). In the perforated appendicitis group overall morbidity (p = 0.046) and wound infection (p = 0.004) was significantly higher in the open appendectomy group. There were no significant differences in intra-abdominal abscesses (p = 0.612). These results suggest that laparoscopic appendectomy for complicated appendicitis is a safe procedure that may prove to have significant clinical advantages over conventional surgery.

    Full Text Available Unilateral-dependent pulmonary edema though reported in laparoscopic donor nephrectomies, has not been reported after laparoscopic non-donor nephrectomies. A 75-kg, 61-year-old man, a diagnosed case of right renal cell carcinoma was scheduled for laparoscopic nephrectomy. After establishing general anesthesia, the patient was positioned in the left-sided modified kidney (flank position. During the 5.75-hour procedure, he was hemodynamically stable except for a transient drop in blood pressure immediately after positioning. Intra-abdominal pressure was maintained less than 15 mmHg throughout the procedure. Blood loss was approximately 50 mL and urine output was 100 mL in the first hour followed by a total of 20 mL in the next 4.75 hours. Total fluid received during the procedure included 1.5 L of Ringer′s lactate and 1.0 L of 6% hydroxyethyl starch. After an uneventful procedure he developed respiratory distress in the postoperative period with a radiological evidence of dependent lung edema. Clinical and radiological improvement followed noninvasive ventilation, intravenous diuretics and oxygen therapy.

    To compare the cost of laparoscopically assisted vaginal hysterectomy (LAVH) with that of total abdominal hysterectomy (TAH) under casemix. Retrospective comparison of the costs, operating time and length of hospital stay. The 16 women undergoing consecutive LAVH and 16 age-matched women undergoing TAH between 1 February 1994 and 31 July 1995; all women were public patients undergoing hysterectomy for benign disease. Monash Medical Centre, a large tertiary teaching hospital in Melbourne, Australia, where casemix is used to determine funding and budget allocation. The difference between the costs of the two procedures was not statistically significant (P = 0.5), despite the cost of laparoscopic hysterectomy including that of disposables. The mean operating time for TAH was 86 minutes (95% CI, 65.5-106.5), compared with 120 minutes (95% CI, 100.8-140.5) for LAVH (P < 0.01). The mean length of stay in the TAH group was 5.75 days, compared with 3.25 days in the LAVH group (P < 0.001). In hysterectomy for benign gynaecological disease, the laparoscopic procedure costs the same as the total abdominal procedure. Audit such as this is important in patient management and in guiding hospitals in funding and bed allocation.

    Diverticular disease is a common condition in Western industrialised countries. Most individuals remain asymptomatic throughout life; however, 25% experience acute diverticulitis. The standard treatment for acute diverticulitis is open surgery. Laparoscopic surgery - a minimal-access procedure - offers an alternative approach to open surgery, as it is characterised by reduced operative stress that may translate into shorter hospitalisation and more rapid recovery, as well as improved quality of life. To evaluate the effectiveness of laparoscopic surgical resection compared with open surgical resection for individuals with acute sigmoid diverticulitis. We searched the following electronic databases: the Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 2) in the Cochrane Library; Ovid MEDLINE (1946 to 23 February 2017); Ovid Embase (1974 to 23 February 2017); clinicaltrials.gov (February 2017); and the World Health Organization (WHO) International Clinical Trials Registry (February 2017). We reviewed the bibliographies of identified trials to search for additional studies. We included randomised controlled trials comparing elective or emergency laparoscopic sigmoid resection versus open surgical resection for acute sigmoid diverticulitis. Two review authors independently selected studies, assessed the domains of risk of bias from each included trial, and extracted data. For dichotomous outcomes, we calculated risk ratios (RRs) with 95% confidence intervals (CIs). For continuous outcomes, we planned to calculate mean differences (MDs) with 95% CIs for outcomes such as hospital stay, and standardised mean differences (SMDs) with 95% CIs for quality of life and global rating scales, if researchers used different scales. Three trials with 392 participants met the inclusion criteria. Studies were conducted in three European countries (Switzerland, Netherlands, and Germany). The median age of participants ranged from 62 to 66 years; 53% to 64% were

    1994-09-01

    Laparoscopic cholecystectomy is both resulting in a slightly higher incidence of biliary lesions and a change of prevalence of the type of lesions. Damage to the biliary system occurs in 4 different types: The most severe case is the lesion with a structural defect of the hepatic or common bile duct with (IVa) or without (IVb) vascular injury. Tangential lesions without structural loss of the duct should be denominated as type III (IIIa with additional lesion to the vessels, type IIIb without). Type II comprehends late strictures without obvious intraoperative trauma to the duct. Type I includes immediate biliary fistulae of usually good prognosis. The increasing prevalence of structural defects of the bile ducts appears to be a peculiarity of laparoscopic cholecystectomy necessitating highly demanding operative repair. In the majority of cases, hepatico-jejunostomy or even intraparenchymatous anastomoses are required. Adaptation of well proven principles of open surgery is the best prevention of biliary lesions in laparoscopic cholecystectomy as well as the readiness to convert early to the open procedure.

  5. Endoscopic and laparoscopic treatment of gastroesophageal reflux.

    2010-04-01

    Gastroesophageal reflux is extremely common in Western countries. For selected patients, there is an established role for the surgical treatment of reflux, and possibly an emerging role for endoscopic antireflux procedures. Randomized trials have compared medical versus surgical management, laparoscopic versus open surgery and partial versus total fundoplications. However, the evidence base for endoscopic procedures is limited to some small sham-controlled studies, and cohort studies with short-term follow-up. Laparoscopic fundoplication has been shown to be an effective antireflux operation. It facilitates quicker convalescence and is associated with fewer complications, but has a similar longer term outcome compared with open antireflux surgery. In most randomized trials, antireflux surgery achieves at least as good control of reflux as medical therapy, and these studies support a wider application of surgery for the treatment of moderate-to-severe reflux. Laparoscopic partial fundoplication is an effective surgical procedure with fewer side effects, and it may achieve high rates of patient satisfaction at late follow-up. Many of the early endoscopic antireflux procedures have failed to achieve effective reflux control, and they have been withdrawn from the market. Newer procedures have the potential to fashion a surgical fundoplication. However, at present there is insufficient evidence to establish the safety and efficacy of endoscopic procedures for the treatment of gastroesophageal reflux, and no endoscopic procedure has achieved equivalent reflux control to that achieved by surgical fundoplication.

    The aim of this study was to describe a minimally invasive laparoscopic jejunostomy (Lap-J) technique for obstruction due to upper gastrointestinal malignancies and evaluate the nutritional benefit of Lap-J during neoadjuvant chemotherapy (NAC) in cases with obstructing esophageal cancer. Under general anesthesia, the jejunum 20–30 cm distant from the Treitz ligament was pulled out through an extended umbilical laparoscopic incision and a jejunal tube was inserted to 30 cm. The loop of bowel was gently returned to the abdomen and the feeding tube was drawn through the abdominal wall via the left lower incision. The jejunum was then laparoscopically sutured to the anterior abdominal wall. Lap-J was performed in 26 cases. The median operative time was 82 min. The postoperative course was uneventful. Lap-J prior to NAC was not associated with a decrease in body weight or serum total protein during NAC, compared with patients who received NAC without Lap-J. This minimally invasive jejunostomy technique may be particularly useful in patients in whom endoscopic therapy is not feasible due to obstruction from upper gastrointestinal malignancies.

    Full Text Available Background. Choledochal cyst is a rare abnormality. Its esti- mated incidence is of 1:100,000 to 150,000 live births. Todani et al. in 1981 reported the main objection for performing a simpler procedure, i.e., hepaticoduodenostomy, has been the risk of an “ascending cholangitis”. This hazard, however, seems to be exaggerated. Methods: A laparoscopic procedure was performed in 8 consecutive patients with choledochal cyst between January 2010 and Septem- ber 2012; 6 females and 2 males mean age was 8 years. Results. Abdominal pain was the main symptom in everyone, jaundice in 1 patient and a palpable mass in 3 patients. Lapa- roscopic surgical treatment was complete resection of the cyst with cholecystectomy and hepaticoduodenostomy laparoscopy in every patient. Discussion and conclusion. A laparoscopic approach to chole- dochal cyst resection and hepaticoduodenostomy is feasible and safe. The hepaticoduodenal anastomosis may confer additional benefits over hepaticojejunostomy in the setting of a laparoscopic approach. The creation of a single anastomosis can decrease operative time and anesthetic exposure.

    Surgical site infections with elective laparoscopic cholecystectomy are less frequent and less severe, leading some to suggest that prophylactic antibiotics (PA) are no longer indicated. We compared the incidence of surgical site infections before and after an institutional practice change of withholding PA for elective laparoscopic cholecystectomy. Between May 7, 2013, and March 11, 2015, no PA were given to patients selected for elective cholecystectomy by two surgeons at a single center. The only patients excluded were those who received antibiotics before surgery for any reason. All others, including those at high risk for infection, were included. The incidence and severity of infections were compared with historical controls treated with prophylaxis by the same two surgeons from November 6, 2011, to January 13, 2013. There were 268 patients in the study group and 119 patients in the control group. Infection occurred in 3.0 per cent in the study group compared with 0.9 per cent in the controls (P = 0.29). All infections were mild except one. Based on these data, the routine use of PA for elective laparoscopic cholecystectomy is not supported.

    The purpose of this study was to determine the feasibility of performing laparoscopic radical prostatectomy in a canine model. Laparoscopic radical prostatectomy was performed on six adult male canines. A new endoscopic needle driver was used to construct a secure vesicourethral anastomosis. Average operative time required to complete the procedure was 304 min (range 270-345 min). Dissection of the prostate gland took an average of 67 min (range 35-90 min), and construction of the vesicourethral anastomosis took 154 min (rage 80-240 min). There were no intraoperative complications and only one postoperative complication (anastomotic leak). Five of the six animals recovered uneventfully from the procedure, and their foley catheters were removed 10-14 days postoperatively after a retrograde cystourethrogram demonstrated an intact vesicourethral anastomosis. Four (80%) of the surviving animals were clinically continent within 10 days after catheter removal. Post mortem examination confirmed that the vesicourethral anastomosis was intact with no evidence of urine extravasation. These data demonstrate the feasibility of laparoscopic radical prostatectomy in a canine model, and suggest that additional work with this technique should be continued to develop its potential clinical application.

    Single-port access laparoscopic lateral segmentectomy (LLS) has been developed as a novel minimally invasive surgery. We have experience with this LLS technique. To report our technique and patients' postoperative course in a series of single-port access LLS performed in our department. We also examine the cosmetic outcome, safety, and utility of the procedure. Between February 2010 and October 2016, 54 patients who underwent single- or multiple-port laparoscopic or open lateral segmentectomy (LS) were retrospectively analyzed with respect to cosmetic outcome, safety, and utility. In the single LLS group, the laparoscopic procedure was successfully completed for all 14 patients. The median operative time was significantly shorter in the single LLS group (123 min; range: 50-270 min) than in the other groups. Estimated blood loss was also significantly lower in the single LLS group (10 ml; range: 0-330 ml). During the first 7 postoperative days, the visual analog scale pain score and the use of additional analgesia were not significantly different between groups. The single LLS group had a 7.1% complication rate (Clavien-Dindo classification > IIIA); this was not significantly different between groups. Single-port access LLS is a procedure with excellent cosmetic results, although, with regard to invasiveness, there are no major differences from conventional LLS.

    To evaluate the clinical advantages of single-port laparoscopic hepatectomy (SPLH) compare to multi-port laparoscopic hepatectomy (MPLH). We retrospectively reviewed the medical records of 246 patients who underwent laparoscopic liver resection between January 2008 and December 2015 at our hospital. We divided the surgical technique into two groups; SPLH and MPLH. We performed laparoscopic liver resection for both benign and malignant disease. Major hepatectomy such as right and left hepatectomy was also done with sufficient disease-free margin. The operative time, the volume of blood loss, transfusion rate, and the conversion rate to MPLH or open surgery was evaluated. The post-operative parameters included the meal start date after operation, the number of postoperative days spent in the hospital, and surgical complications was also evaluated. Of the 246 patients, 155 patients underwent SPLH and 91 patients underwent MPLH. Conversion rate was 22.6% in SPLH and 19.8% in MPLH ( P = 0.358). We performed major hepatectomy, which was defined as resection of more than 2 sections, in 13.5% of patients in the SPLH group and in 13.3% of patients in the MPLH group ( P = 0.962). Mean operative time was 136.9 ± 89.2 min in the SPLH group and 231.2 ± 149.7 min in the MPLH group ( P started earlier in the SPLH group (1.06 ± 0.27 d after operation) than in the MPLH group (1.63 ± 1.27 d) ( P < 0.001). The mean hospital stay after operation was non-significantly shorter in the SPLH group than in the MPLH group (7.82 ± 2.79 d vs 7.97 ± 3.69 d, P = 0.744). The complication rate was not significantly different ( P = 0.397) and there was no major perioperative complication or mortality case in both groups. Single-port laparoscopic liver surgery seems to be a feasible approach for various kinds of liver diseases.

    The advantages of minimally invasive surgery are well accepted. Shorter hospital stays, decreased postoperative pain, rapid return to preoperative activity, decreased postoperative ileus, and preserved immune function are among the benefits of the laparoscopic approach. However, the instruments of laparoscopy afford surgeons limited precision and poor ergonomics, and their use is associated with a significant learning curve and the amount of time and energy necessary to develop and maintain such advanced laparoscopic skills is not insignificant. The robotic surgery allows all laparoscopists to perform advanced laparoscopic procedures with greater ease. The potential advantages of surgical robotic systems include making advanced laparoscopic surgical procedures accessible to surgeons who do not have advanced video endoscopic training and broadening the scope of surgical procedures that can be performed using the laparoscopic method. The wristed instruments, x10 magnifications, tremor filtering, scaling of movements and three-dimensional view allow the urologist to perform the intricate dissection and anastomosis with high precision. The robot is not, however, without significant disadvantages as compared with traditional laparoscopy. These include greater expense and consumption of operating room resources such as space and the availability of skilled technical staff, complete elimination of tactile feedback, and more limited options for trocar placement. The current cost of the da Vinci system is $ 1.2 million and annual maintenance is $ 138000. Many studies suggest that depreciation and maintenance costs can be minimised if the number of robotic cases is increased. The high cost of purchasing and maintaining the instruments of the robotic system is one of its many disadvantages. The availability of the robotic systems to only a limited number of centres reduces surgical training opportunities. Hospital administrators and surgeons must define the reasons for

    Large comparative studies and multiple prospective randomized control trials (RCTs) have reported equivalence in short and long-term outcomes between the open and laparoscopic approaches for the surgical treatment of colon cancer which has heralded widespread acceptance for laparoscopic resection of colon cancer.In contrast,laparoscopic total mesorectal excision (TME) for the treatment of rectal cancer has been welcomed with significantly less enthusiasm.While it is likely that patients with rectal cancer will experience the same benefits of early recovery and decreased postoperative pain from the laparoscopic approach,whether the same oncologic clearance,specifically an adequate TME can be obtained is of concern.The aim of the current study is to review the current level of evidence in the literature on laparoscopic rectal cancer surgery with regard to short-term and long-term oncologic outcomes.The data from 8 RCTs,3 metaanalyses,and 2 Cochrane Database of Systematic Reviews was reviewed.Current data suggests that laparoscopic rectal cancer resection may benefit patients with reduced blood loss,earlier retum of bowel function,and shorter hospital length of stay.Concerns that laparoscopic rectal cancer surgery compromises shortterm oncologic outcomes including number of lymph nodes retrieved and circumferential resection margin and jeopardizes long-term oncologic outcomes has not conclusively been refuted by the available literature.Laparoscopic rectal cancer resection is feasible but whether or not it compromises short-term or long-term results still needs to be further studied.

    Communication is important for patient safety in the operating room (OR). Several studies have assessed OR communications qualitatively or have focused on communication in crisis situations. This study used prospective, quantitative observation based on well-established communication theory to assess similarities and differences in communication patterns between open and laparoscopic surgery. Based on communication theory, a standardized proforma was developed for assessment in the OR via real-time observation of communication types, their purpose, their content, and their initiators/recipients. Data were collected prospectively in real time in the OR for 20 open and 20 laparoscopic inguinal hernia repairs. Assessors were trained and calibrated, and their reliability was established statistically. During 1,884 min of operative time, 4,227 communications were observed and analyzed (2,043 laparoscopic vs 2,184 open communications). The mean operative duration (laparoscopic, 48 min vs open, 47 min), mean communication frequency (laparoscopic, 102 communications/procedure vs open, 109 communications/procedure), and mean communication rate (laparoscopic, 2.13 communications/min vs open, 2.23 communications/min) did not differ significantly across laparoscopic and open procedures. Communications were most likely to be initiated by surgeons (80-81 %), to be received by either other surgeons (46-50%) or OR nurses (38-40 %), to be associated with equipment/procedural issues (39-47 %), and to provide direction for the OR team (38-46%) in open and laparoscopic cases. Moreover, communications in laparoscopic cases were significantly more equipment related (laparoscopic, 47 % vs open, 39 %) and aimed significantly more at providing direction (laparoscopic, 46 % vs open, 38 %) and at consulting (laparoscopic, 17 % vs open, 12 %) than at sharing information (laparoscopic, 17 % vs open, 31 %) (P communications were found in both laparoscopic and open cases during a relatively low

    Laparoscopic distal gastrectomy has recently become accepted as a surgical option for early gastric cancer in the distal stomach, but laparoscopic total gastrectomy (LTG) has not become widespread because of technical difficulties of esophagojejunal anastomosis and splenic hilar lymphadenectomy. Splenic hilar lymphadenectomy should be employed in the treatment of advanced proximal gastric cancer to complete D2 dissection, but laparoscopically it is technically difficult even for skilled surgeons. Based on the evidence that prophylactic combined resection of spleen in total gastrectomy increased the risk of postoperative morbidity with no survival impact, surgeons have preferred laparoscopic spleen-preserving splenic hilar lymphadenectomy (LSPL) for advanced tumors without metastasis to splenic hilar nodes or invasion to the greater curvature of the stomach, and reports with LSPL have been increasing rather than LTG with splenectomy. In this paper, recent reports with laparoscopic splenic hilar lymphadenectomy were reviewed.

    2017-01-01

    Objectives: Benign paroxysmal positional vertigo is a common vestibular disorder and it may be idiopathic or secondary to some conditions such as surgery, but rare following laparoscopic surgery. Methods: We report two cases of benign paroxysmal positional vertigo secondary to laparoscopic surgery, one after laparoscopic cholecystectomy in a 51-year-old man and another following laparoscopic hysterectomy in a 60-year-old woman. Results: Both patients were treated successfully with manual or device-assisted canalith repositioning maneuvers, with no recurrence on the follow-up of 6 -18 months. Conclusions: Benign paroxysmal positional vertigo is a rare but possible complication of laparoscopic surgery. Both manual and device-assisted repositioning maneuvers are effective treatments for this condition, with good efficacy and prognosis. PMID:28255446

    2005-10-01

    Full Text Available Abstract Background Rectovaginal fistula (RVF is an epithelium-lined communication between the rectum and vagina. Most RVFs are acquired, the most common cause being obstetric trauma. Most of the high RVFs are repaired by conventional open surgery. Laparoscopic repair of RVF is rare and so far only one report is available in the literature. Methods We present a case of high RVF repaired by laparoscopy. 56-year-old female who had a high RVF following laparoscopic assisted vaginal hysterectomy was successfully operated laparoscopically. Here we describe the operative technique and briefly review the literature. Results The postoperative period of the patient was uneventful and after a follow up of 6 months no recurrence was found. Conclusion Laparoscopic repair of high RVF is feasible in selected patients but would require proper identification of tissue planes and good laparoscopic suturing technique.

    Standardized short courses in laparoscopic cholecystectomy aim to teach laparoscopic skills to surgical trainees, although end-of-course assessments of performance remain subjective. The current study aims to objectively assess psychomotor skills acquisition of trainees attending laparoscopic cholecystectomy courses. Thirty-seven junior surgical trainees had their laparoscopic skills assessed before and after attending 1 of 3 separate 2-day courses (A, B, and C), all with identical format. Assessments were comprised of a standardized simulated laparoscopic task, with performance measured using a valid electromagnetic hand-motion tracking device. Overall, trainees made significant improvements in path length (P=.006), number of movements (Ppsychomotor skills on courses. In addition to providing participants with an insight into their skills, these data can be used to demonstrate course efficacy.

  19. Secrets of safe laparoscopic surgery: Anaesthetic and surgical considerations

    Directory of Open Access Journals (Sweden)

    Srivastava Arati

    2010-01-01

    Full Text Available In recent years, laparoscopic surgery has gained popularity in clinical practice. The key element in laparoscopic surgery is creation of pneumoperitoneum and carbon dioxide is commonly used for insufflation. This pneumoperitoneum perils the normal cardiopulmonary system to a considerable extent. Every laparoscopic surgeon should understand the consequences of pneumoperitoneum; so that its untoward effects can be averted. Pneumoperitoneum increases pressure on diaphragm, leading to its cephalic displacement and thereby decreasing venous return, which can be aggravated by the position of patient during surgery. There is no absolute contraindication of laparoscopic surgery, though we can anticipate some problems in conditions like obesity, pregnancy and previous abdominal surgery. This review discusses some aspects of the pathophysiology of carbon dioxide induced pneumoperitoneum, its consequences as well as strategies to counteract them. Also, we propose certain guidelines for safe laparoscopic surgery.

    Recently, there has been a growth in studies supporting the hypothesis that video games have positive effects on basic laparoscopic skills. This review discusses all studies directly related to these effects. A search in the PubMed and EMBASE databases was performed using synonymous terms for video games and laparoscopy. All available articles concerning video games and their effects on skills on any laparoscopic simulator (box trainer, virtual reality, and animal models) were selected. Video game experience has been related to higher baseline laparoscopic skills in different studies. There is currently, however, no standardized method to assess video game experience, making it difficult to compare these studies. Several controlled experiments have, nevertheless, shown that video games cannot only be used to improve laparoscopic basic skills in surgical novices, but are also used as a temporary warming-up before laparoscopic surgery.
