Sleeve gastrectomy can cause functional stenosis due to spiral stapling, leading to dysphagia. Converting to Roux-en-Y gastric bypass (RY-GBP) resolved symptoms and improved quality of life in a patient.
Area of Science:
- Bariatric Surgery
- Gastroenterology
- Surgical Complications
Background:
- Sleeve gastrectomy (SG) is a popular bariatric procedure with increasing rates globally.
- Gastric stricture is a known early complication of SG, occurring in 0.7-4.0% of patients.
- Functional stenosis, distinct from anatomic stricture, can arise from spiral stapling during SG, causing recurrent dysphagia.
