Abstract

Single-anastomosis duodenal switch (SADS) has become increasingly popular. This review compared the conceptual difference between Eastern (SADS-E) and Western (SADS-W) countries. After searching for SADS through PubMed and high-impact journals, 19 articles with 2280 patients were included for analysis. We found SADS-W was reserved for patients with a high body mass index (BMI) without type 2 diabetes mellitus (T2DM). Surgeons performing SADS-W used larger bougies and preferred shorter common channels. However, SADS-E was mainly preferred in T2DM patients with a low BMI. SADS-E bypassed less bowel and used smaller bougies. The spectra of major postoperative complications, nutritional deficiencies, and gastrointestinal disorders were different between SADS-E and SADS-W. SADS-W yielded better weight loss and better T2DM remission than SADS-E. SADS are effective bariatric and metabolic procedures with promising therapeutic outcomes and acceptable safety.
