Management of post-bariatric complications. Our Center experience and literature review.

Bariatric surgery is recognized as the most effective treatment for morbid obesity, maintaining a stable weight reduction in the long term and reducing comorbidities, with a favorable impact on mortality. The aim of this study is to evaluate the complication rate and treatment techniques adopted in all patients undergoing bariatric surgery procedures in our center. From May 2017 to March 2020, 91 patients with morbid obesity are admitted to the Department of Medical and Surgical Science of the University Hospital of Foggia undergoing bariatric surgery. Seventyone patients underwent sleeve gastrectomy, nineteen gastric bypass and one mini-gastric bypass, five of these were redo operation procedures. Regarding postoperative complications (8,8%), there were 1 gastric leak (1,09%), 4 bleedings (4,39%) - 1 intraluminal bleeding and 3 intra-abdominal bleedings, 2 port-sites infections (2,19%) and 1 haemoperitoneum (1,09%). In our center we have also treated 3 cases of complications after bariatric surgery procedures performed in others centers. There were no deaths. Despite improvement in the performance of bariatric surgical procedures, complications are not uncommon. Flexible endoscopy has become an essential tool in managing bariatric surgery patients and offers the benefit of providing both diagnostic and therapeutic applications.
