Comparison of MGB with SADI-S: Revision of Sleeve Gastrectomy to MGB or Single Anastomosis Duodeno-Ileostomy (SADI)

  • Arun Prasad


SADI-S is a sleeve gastrectomy (SG) with proximal duodenal division and end-to-side anastomosis 250 cm proximal to ileocecal valve. SADI-S appears to have some disadvantages compared to the MGB. Both show excellent improvement in co-morbidities, but no comparison has been reported.

Revision of SG for inadequate weight loss or weight regain is now becoming the main reason for revision bariatric surgery. Two revisions` which appear technically simple but give good weight and metabolic results are the MGB and the SADI. We did a comparative study of these procedures with a 2-year follow-up. Both procedures were done robotically by a single surgeon in patients with comparable demography. While weight loss was comparable after both procedures, nutritional deficiencies and GI symptoms were higher with SADI. Thus, MGB is our preferred choice.
