Laparoscopic conversion of sleeve gastrectomy to a biliopancreatic diversion with duodenal switch or a Roux-en-Y gastric bypass due to weight loss failure: our algorithm
Changing sleeve gastrectomy to two types of weight-loss surgery when it doesn't work: our step-by-step approach

Abstract
The mean pre-surgery weight for patients undergoing biliopancreatic diversion with duodenal switch (DS) was 143±36 kg.
- Patients converted to DS had a mean body mass index (BMI) of 51.5±11 kg/m2 prior to surgery.
- The average time between sleeve gastrectomy (SG) and conversion to DS was 27±18 months, while it was 36±17 months for Roux-en-Y gastric bypass (RYGB).
- Operation times averaged 191±64 minutes for DS and 111±37 minutes for RYGB, with hospital stays of 4.3±2.4 days and 3.1±1.1 days, respectively.
- Post-surgery, the DS group achieved a weight of 84±19 kg and a percentage of excess weight loss (%EWL) of 80±40%.
- The RYGB group had a post-surgery weight of 81±21 kg and an %EWL of 65.5±34%.
- Both procedures are feasible after SG failure, with DS potentially resulting in greater weight loss.
