A Matched Cohort Analysis of Stomach Intestinal Pylorus Saving (SIPS) Surgery Versus Biliopancreatic Diversion with Duodenal Switch with Two-Year Follow-up.
BACKGROUND: In bariatric surgery, the procedure with the highest average weight loss is the biliopancreatic diversion with duodenal switch (BPDDS). A new simplified duodenal switch called the stomach intestinal pylorus sparing (SIPS) surgery with less malabsorption and one fewer anastomosis claims to have similar outcomes when compared to the BPDDS. METHODS: A retrospective matched cohort analysis of SIPS versus BPDDS patients in a single private practice was obtained by matching every BPDDS to a SIPS patient of the same gender and BMI. Excess weight loss percentage (EWL), BMI, and percentage total weight loss (%TWL) were compared. Additionally, comorbidity resolution, nutritional data, and complications were also compared. Data was analyzed using both descriptive and comparative statistics. RESULTS: Over 2 years, there was no statistical difference in weight loss between BPDDS and SIPS. There also was no difference in nutritional data between the two procedures pre- and post-op. Complication rates were lower in SIPS however, due to the small sample sizes this is not statistically significant. CONCLUSION: Weight loss and nutritional results between SIPS and BPDDS are similar at 2 years. However, there are fewer complications with SIPS.
