Retrograde jejunojejunal intussusception in a pregnant female after laparoscopic Roux-en-Y gastric bypass.

Adult intussusception is a rare complication after laparoscopic Roux-En-Y gastric bypass (LRYGB) surgery. Incidence of intussusception is on the rise as the demand of bariatric surgeries is increased to treat morbid obesity. Among the bariatric surgeries, LRYGB gastric bypass results in significantly higher weight loss with thinning of the mesentery resulting in increased risk for intussusception.

Transanal rectosigmoid resection via natural orifice translumenal endoscopic surgery (NOTES) with total mesorectal excision in a large human cadaver series.

Background: The authors' group has previously described successful transanal rectosigmoid resection via natural orifice translumenal endoscopic surgery (NOTES) in both porcine and cadaveric models using the transanal endoscopic microsurgery platform. This report describes the largest cadaveric series to date as optimization of this approach for clinical application continues.

Methods: Between December 2008 and September 2011, NOTES transanal rectosigmoid resection with total mesorectal excision (TME) was successfully performed in 32 fresh human cadavers using transanal dissection alone (n = 19), with transgastric endoscopic assistance (n = 5), or with laparoscopic assistance (n = 8).
