A comparative evaluation of five-year results of SADI-S and biliopancreatic diversion/Duodenal switch (Hess-Marceau)

Background. Although Biliopancreatic Diversion (BPD) currently is infrequently used in metabolic surgery, SADI-S (Single Anastomosis DuodenoIleal + Sleeve) technique may revive interest to hypoabsorptive surgery not only as a second-step but also as a primary metabolic procedure. There are only small comparative studies between SADI-S and Hess-Marceau's BPD/Duodenal Switch (BPD/DS) operations.Objectives. To evaluate retrospectively 5-year experience of SADI-S with common limb of 250 cm (SADI-S 250) and to compare results with standard Hess-Marceau's BPD/DS.Methods. 226 patients underwent SADI-S 250 with Sleeve Gastrectomy (SG) between May 2014 and August 2019. Diabetes mellitus type 2 (DM2) was diagnosed in 80 (35,4 %). Patients who underwent second-step SADI-S after previous SG were not included. General follow-up rate after SADI-S was 98,2%. Percent of Excess weight loss (EWL), antidiabetic effect, complications and revision rate were compared with results of BPD/DS in series of 528 patients operated within years 2003-2015 (general follow-up rate - 99,2%)...
