Sleeve Stenosis, Torsion, and Delayed Emptying

Over the past decade, sleeve gastrectomy (SG) has emerged as the leading bariatric surgery worldwide, constituting 55.4% of all procedures in 2018. Sleeve gastrectomy has uncommon but significant complications: sleeve stenosis, torsion, and delayed gastric emptying, which are crucial for clinicians to recognize and manage effectively. Sleeve stenosis, occurring in 0.2–4% of cases, with symptoms such as nausea and requires endoscopic or surgical intervention. Torsion, a form of functional stenosis, results from anatomical alterations post-SG, necessitating diagnostic laparoscopy and potential surgical correction. Delayed gastric emptying calls for dietary modifications, medical intervention with the involvement of gastroenterology and motility specialists, as well as possible surgical revision of SG. This comprehensive review emphasizes the importance of a multidisciplinary approach to optimize patient outcomes and manage these complex postoperative scenarios in the evolving field of bariatric surgery.
