Background

Single Anastomosis Duodeno-Ileostomy (SADI-S) Versus One Anastomosis Gastric Bypass (OAGB/MGB) as Revisional Procedures for Patients with Weight Recidivism after Sleeve Gastrectomy: a Comparative Evaluation of the Efficacy and Outcomes in 91 Patients at a Single Center

Methods

A retrospective analysis of a prospective collected data base of patients who underwent SADI or OAGB/MGB as a revisional procedure for weight recidivism after primary LSG and followed for a minimum of one year was conducted. Patients in both study groups were compared in terms of weight loss, comorbidities resolution, nutritional deficiencies and complication rates.

Results

Ninety-one patients were included in the study (42 underwent SADI and 49 OAGB/MGB). A slight advantage in weight loss (total weight loss percentage, TWL %) at one year follow-up was observed for SADI when compared to OAGB/MGB (23.7±5.7 vs. 18.7±8.5, p=0.02). However, this was comparable at 18 months follow-up (26.4±7.3 vs. 21.2±11.0, p=0.25). Remission of comorbidities (diabetes and hypertension) and vitamin deficiency were similar in both study groups. Although OAGB/MGB had higher complication rate than SADI, the difference was not statistically significant (27% vs. 19%, p = 0.39). No mortality was reported in either of the study groups.

Conclusions

Both SADI-S and OAGB/MGB were effective revisional procedures to deal with weight regain post LSG with comparable outcomes in short term follow up. SADI-S procedure appears to cause less upper gastrointestinal complications and even looks a good option for patients suffering from GERD post primary LSG
