RESUMO
La derivación biliopancreática con cruce duodenal (BPD-DS) es el procedimiento bariátrico que ha mostrado los mejores resultados en cuanto a pérdida de peso y resolución de comorbilidades. Sin embargo, su adopción ha sido lenta, principalmente debido a sus complicaciones nutricionales y dificultad técnica. Dado esto, algunos autores han propuesto variaciones de este procedimiento. Estas están basadas en disminuir las anastomosis a solo una, y realizarla con un asa tipo loop (sin derivación biliopancreática). Estos cambios podrían reproducir las ventajas del BPD-DS, y eliminar algunas de sus desventajas. En este artículo, mostramos los resultados de estas variaciones comparadas con el BPD-DS, y cómo sus resultados prometedores pueden tener como consecuencia una nueva aproximación a la población que sufre de obesidad y sus comorbilidades
Biliopancreatic Diversion with duodenal switch (BPD-DS) is the bariatric surgery that has shown the better results regarding long-term weight loss and comorbidities resolution. Nevertheless, BPD-DS' adoption has been slow, mainly due to its nutritional complications, and technical complexity. Given this, some authors have proposed surgical variations of this effective procedure. These new procedures are based on reducing the anastomosis to only one, and doing it just a loop anastomosis (no biliopacreatic diversion). These changes might bring to us the advantages of BPD-DS, and eliminate some of its disadvantages. In this article, we show the results of these variations compared with BPD-DS, and how their promising results could be a new approach for obese population and bariatric surgery.

BACKGROUND AND OBJECTIVE: The Roux-en-Y duodenal switch (RYDS) is one of the most efficient forms of bariatric surgery. However, diarrhea, malnutrition, ulcers, and internal hernias have hampered its widespread adoption. The stomach intestinal pylorus-sparing (SIPS) procedure was developed to alleviate these sequelae while retaining the same weight loss as the RYDS. In this study, we report our midterm experience with this novel technique. METHODS: Retrospective analysis was performed on data from 225 patients who underwent a primary SIPS procedure by 2 surgeons at a single center from October 2013 through December 2016. RESULTS: Two hundred twenty-five patients were identified for analysis. The mean preoperative body mass index (BMI) was 52.4 ± 9.1 kg/m2. Forty-eight patients were beyond 2 years after surgery, with data available for 30 patients (62.5% follow-up). Three patients were lost to follow-up. At 2 years, the patients had an average change in BMI of 26.6 U (kg/m2) with an average of 88.7% of excess weight loss. Three deaths were related to the surgery. The most common short-term complication was a leak (2.2%), whereas the most common long-term complication was diarrhea (2.2%). CONCLUSION: In conclusion, SIPS surgery is a safe procedure with favorable weight loss outcomes at 2 years.
