Effect of Suture Used for Closure of Mesenteric Defects After Laparoscopic Roux-en-Y Gastric Bypass: Single-Center Study.

Introduction: Small bowel obstruction (SBO) due to internal herniation (IH) is a well-known complication of laparoscopic Roux-en-Y gastric bypass (LRYGBP). The objective of this study is to evaluate different types of non-absorbable sutures used for closure of the defects regarding the incidence of SBO due to IH/adhesions, adhesion formation in general, or reopening of the defects.

Methods: A single-center retrospective study was performed.

Internal Hernia After Laparoscopic Gastric Bypass: Effect of Closure of the Petersen Defect - Single-Center Study.

Background And Aims: Bowel obstruction due to internal hernia (IH) is a well-known late complication of a laparoscopic roux-en-y gastric bypass (LRYGBP). The objective of this study is to evaluate if closure of the mesenteric defect and Petersen's space will decrease the rate of internal hernias compared to only closure of the mesenteric defect.

Methods: A single-center retrospective descriptive study was performed.

An unusual cause of chronic abdominal pain after laparoscopic Roux en Y gastric bypass: Case report of a penetrating fish bone causing adhesions at the biliary-digestive junction resulting in partial obstruction and chronic symptoms.

Background: The management of chronic abdominal pain after laparoscopic Roux-en-Y gastric bypass (LRYGP) is complex and challenging. Foreign body intestinal perforation including that caused by fish bones has previously been reported in the literature and if clinically unrecognized, can cause significant morbidity and mortality. Fish bone perforation as a cause of chronic abdominal pain after LRYGP has rarely been reported.

Contraceptive treatment after biliopancreatic diversion needs consensus.

Background: An important population of patients who undergo biliopancreatic diversion (BPD) are fertile women. A consensus is needed with regard to contraceptive therapy after BPD by evaluating the risks of pregnancy, the safety of oral contraception and the changes in fertility after this bariatric surgery.

Method: From May 1997 until May 1998, 40 women who underwent a BPD were included in a prospective study evaluating the hormone status preoperatively and postoperatively after 2 and 7 days, 3 and 6 months and 1 year.

A technique for prevention of port complications after laparoscopic adjustable silicone gastric banding.

Background: Laparoscopic adjustable gastric banding is a safe and effective treatment method for morbid obesity. Injection port dislocation, tube perforation and access port infection are generally classified among the minor complications, although they can require a reoperation at the port-site or even at the level of the band which may have to be removed. We designed a technique to fix the port, that can avoid unnecessary complications.
