Brief Communication


Single anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S) can be considered as either a primary procedure or second stage procedure. Malnutrition is rare but could lead to a reversal of the SADI-S. The aim of this manuscript is to present the management and technique of weight regain after proximalization of a SADI-S by converting it to a gastric bypass.
