Ileocolonic intussusception due to severe endometriosis.

Endometriosis is the presence of normal endometrial tissue outside the uterus, which may appear in up to 15% of fertile female population. Bowel endometriosis is uncommon, and obstruction due to endometrial ileocolic intussusception is extremely rare. Herein, we report a case of a 27-year-old female who presented with bowel obstruction due to ileocolic intussusception secondary to endometriosis. A 27-year-old female, without pregnancies, and with a 1 year history of endometriosis presented to the emergency department referring severe abdominal pain in right lower quadrant, nausea and vomiting, she had medical history of prior episodes of mild abdominal pain due to endometriosis with OB/GYN follow-up. Physical examination revealed abdominal distension with decreased bowel movements to auscultation. A CT scan reported suspicion of intussusception. Colonoscopy was ordered, where an ileocolic intussusception was found. Diagnostic laparoscopy was performed, and the initial diagnosis was confirmed. A right hemicolectomy with extracorporeal anastomosis was achieved without any surgical complications. The patient was discharge on postoperative day 4 and continues doing well on a 12 month follow-up. Ileocolic intussusception due to endometriosis is a very rare condition, and it must be considered a differential diagnosis in female patients in reproductive age, when presenting with intestinal obstruction.

Effect of Surgical Expertise on Biomechanical Properties of Sutures After Abdominal Wall Closure.

BACKGROUND: Despite preventive methods and careful surgical technique, surgical site infection and incisional hernias are of main concern after the closure of surgical incisions and keep haunting abdominal wall wound healing. The aim of this study is to find how surgical expertise level modifies biomechanical properties of sutures commonly used in abdominal wall fascial closure (polypropylene, polyglactin 910, polydioxanone). MATERIALS AND METHODS: Surgery residents with different experience levels performed abdominal wall fascial closure in swine models with the previously mentioned suture materials. A standardized technique was used. Sutures were removed, and a tensile stress test was performed on the removed sutures. A total of 81 abdominal fascial closures were achieved. Time, extension, maximum tensile force (Ftmax), and maximum stress were measured and analyzed. RESULTS: The results of the polydioxanone stress test present a trend in three variables: extension, tensile force, and stress. The trend shows higher medians in the expert group and lower medians in the novice group. While using polypropylene sutures, medians in the expert group are the highest; however, a trend is not observed. Polyglactin 910 sutures have nonspecific behavior among the different experience groups and variables. Polypropylene is the material with the lowest Ftmax tested and fails at 42.64 (IQR 40.98-44.89) N. Regarding the elastic properties of the material, polyglactin demonstrates the least extension of all sutures tested, with a 14 (IQR 13.33-14.83) mm extension. This study demonstrates that polydioxanone has a superior Ftmax compared with polypropylene and has a superior extension at failure properties compared with polyglactin, confirming that polydioxanone could be the suture of choice used for abdominal wall fascial closure. CONCLUSIONS: Study results do not show statistically significant differences regarding the impact of the experience level of different general surgery residents in the biomechanical properties of sutures used in abdominal wall fascial closure.

Transjejunal Laparoscopic Assisted ERCP in a Patient with Roux-en-Y Hepaticojejunostomy.

Background and Objectives: Nowadays, with the increasing laparoscopic expertise and accessibility to modern surgical tools, laparoscopic assisted ERCP (LAERCP) has become an effective approach for the management of bile stone disease in patients with modified gastrointestinal anatomy. In contrast to patients with gastric bypass in whom a transgastric LAERCP approach is usually performed, the resultant anatomy of Roux-en-Y hepaticojejunostomy precludes a gastric approach as the newly formed bilioenteric anastomosis is not reachable through the stomach. Therefore, a transjejunal approach has been described as an alternative LAERCP technique. To the best of our knowledge this is the tenth case of transjejunal LAERCP reported worldwide. Materials and Methods: We present the case of a 50-year-old female with history of biliary injury during a cholecystectomy corrected with Roux-en-Y hepaticojejunostomy who presented to our center with manifestations of acute abdomen. After laboratory and image analysis, diagnosis of intrahepatic lithiasis was confirmed. The decision to perform a transjejunal LAERCP was made due to the complex anatomy in this patient. No complications were found during surgery and in the follow up period. Conclusions: Transjejunal LAERCP is an effective approach for endoscopic management of biliary complications in patients with Roux-en-Y hepaticojejunostomy and other modified gastrointestinal anatomy. Previous recommendations by more experienced teams have been reported, nonetheless, there are too few cases reported to make definitive recommendations and conclusions. In limited settings, such as ours, some of these recommendations may not be applicable. We are certain that, with the increasing expertise and innovations in laparoscopy surgery for the management of complications that cannot be addressed by endoscopic or noninvasive measures, more cases will be reported.

Laparoscopy-assisted transgastric endoscopic retrograde cholangiopancreatography for choledocholithiasis after Roux-en-Y gastric bypass: A case report.

BACKGROUND: Exclusion of the stomach after Roux-en-Y gastric bypass (RYGB) makes access to the biliary tree very challenging for the surgeon or the endoscopist. Different techniques have been described to overcome this downside, including laparoscopy-assisted transgastric endoscopic retrograde cholangiopancreatography (ERCP), which is an outstanding method to access the remnant stomach in order to reach the duodenal papilla. The use of this technique is associated with a high success rate. PRESENTATION OF CASE: Here we present the case of a 57-year-old patient with altered RYGB anatomy. The patient underwent laparoscopic cholecystectomy. Intraoperative cholangiography revealed the presence of a stone in the common bile duct. A laparoscopy-assisted transgastric ERCP was performed successfully. During the procedure, the duodenoscope was introduced through a gastrostomy, obviating the need for an intragastric trocar. The patient evolved favorably and was discharged on second postoperative day without any complications. DISCUSSION: Transgastric laparoscopy-assisted ERCP represents an effective approach for the management of biliary complications after RYGB, even if there is a long interval between the two interventions, as occurred in the present case. Other methods described for accessing the biliary tree in patients with altered RYGB anatomy are double-balloon ERCP and endoscopic ultrasound-directed transgastric ERCP. We elected to perform the laparoscopy-assisted approach because choledocholithiasis was diagnosed transoperatively, thus, avoiding the need for secondary procedures or interventions. CONCLUSION: Transgastric laparoscopy-assisted ERCP is a feasible procedure with low complication rates and is used in treating patients with altered RYGB anatomy who present with biliary tract disorders. The use of transgastric laparoscopy-assisted ERCP allows endoscopic treatment and cholecystectomy to be performed in a single setting.
