Background
There are no comparative studies on the long-term outcomes after the primary traditional duodenal switch (DS) and single-anastomosis duodeno-ileostomy with sleeve gastrectomy (SADI-S).
Purpose
This study aims to compare the long-term outcomes in a matched cohort.
Setting
This study took place in a single private institute, in the USA.
Materials and Methods
Data from 266 patients who underwent a primary laparoscopic traditional DS or primary laparoscopic SADI-S from September 2011 to December 2015 by four surgeons were used for a retrospective matched cohort. Data were obtained by matching every DS patient to a SADI-S patient of the same age, sex, and body mass index (BMI). In addition, only patients that were out at least 5 years and had a minimum 5-year follow-up were included in the study.
Results
The matched cohort included 30 DS and 30 SADI-S patients. There were no statistically significant differences in the preoperative characteristics and baseline comorbidities between both groups. The SADI-S patients had significantly shorter operative time and length of stay. The overall long-term complications, especially the long-term Clavien-Dindo grade IIIb complications, were significantly fewer with SADI-S. At 6 years, the DS patients had statistically higher %EWL; however, the ending BMIs were statistically similar between both groups. There were no significant differences in the long-term comorbidity and nutritional outcomes of both groups. The long-term failure rates were comparable.
Conclusions
Most long-term outcomes of SADI-S were either similar or significantly better than DS. Part of the reasons could be the surgeon’s learning curve and the small sample sizes of both groups.
