Duodenal switch gastric bypass surgery for morbid obesity: imaging of postsurgical anatomy and postoperative gastrointestinal complications.
OBJECTIVE
The purpose of our study was to evaluate the normal postsurgical findings and appearance of gastrointestinal tract complications in patients who have undergone biliopancreatic diversion with duodenal switch bariatric surgery. We performed a 4-year retrospective review of 218 patients who underwent duodenal switch surgery.


CONCLUSIONS
The most common complications of duodenal switch surgery were bowel obstruction, followed by ventral hernias and anastomotic leaks. Only 2% of cases required repeat surgery for management.
