Gastrointestinal Obstruction After Bariatric Surgery

Bowel obstruction is a significant and potentially life-threatening complication following bariatric surgery, affecting procedures like Roux-en-Y gastric bypass, sleeve gastrectomy, and biliopancreatic diversion with duodenal switch. The clinical manifestations of bowel obstruction vary widely, depending on the site and nature of the blockage, ranging from nausea and vomiting to severe abdominal pain and distension. Prompt diagnosis and management are crucial, utilizing advanced imaging techniques such as computed tomography (CT) scans to identify the obstruction site and guide treatment. This chapter delves into the evaluation and therapeutic strategies for various types of bowel obstructions post-bariatric surgery, highlighting the importance of tailored surgical interventions and the role of endoscopic procedures in alleviating strictures. The comprehensive understanding of these complications is essential for optimizing patient outcomes and minimizing morbidity.
