GASTROJEJUNAL ANASTOMOTIC STRICTURES AFTER BYPASS OPERATIONS: PREVENTION AND TREATMENT

Gastrojejunal anastomotic strictures represent a significant complication following Roux-en-Y gastric bypass (RYGB) surgery, occurring in 3-27% of patients and substantially impacting quality of life and nutritional status. This comprehensive review examines the etiology, risk factors, prevention strategies, and treatment modalities for anastomotic strictures in bariatric surgery. Understanding the pathophysiology of stricture formation and implementing evidence-based prevention and treatment protocols is essential for optimizing patient outcomes and minimizing long-term complications. Current management approaches include endoscopic balloon dilation, bougie dilation, steroid injection, and surgical revision, with success rates varying from 70-95% depending on stricture characteristics and treatment modality
