Internal Hernia Following Primary Laparoscopic SADI-S: the First Reported Case

Background Internal hernias have not been reported with primary laparoscopic single anastomosis duodeno-ileostomy with sleeve gastrectomy (LSADI-S). This is the first reported case of an internal hernia following primary LSADI-S and its surgical treatment. Case Presentation In this video case report, we present a case of a 54-year-old woman with a BMI of 53 kg/m2 who had undergone a primary LSADI-S for morbid obesity. The patient underwent an exploratory laparoscopy for chronic nausea and bile reflux. At surgery, we discovered a Petersen's hernia defect, which was corrected by untwisting the bowel and sewing the space closed (video). A Braun enteroenterostomy was also performed. Conclusions An internal hernia following LSADI-S is rare, despite the unclosed space behind the small bowel mesentery. If they occur, they should not cause ischemia and can be fixed easily using a laparoscopic surgical approach with good postoperative outcomes.
