title: Laparoscopic re-exploration in mechanical bowel obstruction after laparoscopic gastric bypass for morbid obesità.
abstract: OBJECTIVE
  This study reports a series of 7 patients who experienced small-bowel obstruction (SBO) after laparoscopic gastric bypass (LGBP).
  
  
  METHODS
  Between July 2001 and June 2004, 211 patients underwent surgery for morbid obesity in 2 different institutions and 7 of them required reoperative laparoscopic surgery or laparotomy for mechanical SBO.
  
  
  RESULTS
  Seven patients in the series (3%) developed a postoperative bowel obstruction requiring operative management. Their mean body mass index was 49 (range: 38-65) and the average age was 48 years (range 29-60). Six (86%) had undergone an initial LGBP. One (14%) had been converted to open surgery because of the presence of thick adhesions. One percent of the patients (14%) had undergone abdominal surgery prior to gastric bypass. The most common cause of SBO was internal hernia through a mesenteric defect (57%), followed by adhesions (14%), obstruction at the entero-enterostomy (14%) and Petersen hernia (14%). The obstruction was managed laparoscopically. Small-bowel resection was required in 14% with no death encountered after the second revision of the entero-enterostomy. Recovery time was less than 72 h after laparoscopic approach and more than 92 h following the open procedure.
  
  
  CONCLUSIONS
  Laparoscopic surgical correction of SBO following LGBP in morbidly obese patients is feasible. Reoperation of morbidly obese patients after LGBP can be achieved successfully through laparoscopic techniques.
