Patients undergoing SADI-S may experience GERD symptoms and diarrhea at a rate of up to 30% during a follow-up period exceeding three years. Utilizing validated objective assessments to monitor postoperative patient symptoms appears to be a practical and valuable approach for long-term follow-up care in SADI-S patients.

Early correction of deficiencies, regular lab monitoring, and multidisciplinary follow-up also contribute to positive results. However, the study recommended further research to refine dosing guidelines for essential nutrients after advanced weight-loss surgeries.

Additional studies are warranted to identify more favorable revisional bariatric procedures following unsuccessful SG.

Revisional laparoscopic SADI-S vs. duodenal switch following failed primary sleeve gastrectomy: a single-center comparison of 101 consecutive cases. Obes Surg. 2021;31(8):3667–74. This single-institution study on revisional surgery post-sleeve Gastrectomy (SG) suggests that Duodenal Switch (DS) offers better weight control and diabetes/hypertension resolution than SADI-S at 2 and 5 years. DS, however, requires more vitamins and micronutrient supplementation. DS may be preferable for patients with inadequate weight loss or regain post-SG, especially those with severe obesity or persistent diabetes/hypertension. Suggesting further research for a better understanding of SADI-S/DS as revisional procedures.

Langenbeck's Arch Surg. 2022;407(5):1851–62. SADI-S, with its minimal early complication rates, proves its safety, especially when conducted in specialized centers. It stands as a viable option for treating super-obese patients and those with unsatisfactory outcomes post-sleeve gastrectomy. Yet, establishing national and international registries is crucial for obtaining standardized data and analyzing long-term bariatric and metabolic effects across a broad patient cohort.

In this multicenter study, BPD-DS showed a higher percentage of Total Body Weight Loss (%TBWL) after two years. However, upon stratifying study groups, the initial hypothesis of potential procedural superiority was disproven, revealing similar weight loss between BPD-DS and SADI-S. SADI-S was linked to shorter operative times and hospital stays, with no significant increase in complication rates, except for higher rates of emergency department visits compared to the BPD-DS group.

There is no internationally recognized definition of bariatric surgery. It is anticipated that the rising frequency of sleeve gastrectomy procedures will correspondingly lead to an increase in the need for revisional surgeries. Conversion to Roux-en-Y Gastric Bypass is likely the most common operation performed for weight loss failure and GERD, with metabolic effects similar to primary RYGB.

This review provides additional evidence in multiple comorbid states, that at the twelve months following SADI-S, the rates of resolution for comorbidities were 72.6% for diabetes, 77.2% for dyslipidemia, and 59.0% for hypertension. Reoperation necessity emerged as the primary postoperative complication. Despite some patients experiencing nutrient deficiencies, SADI-S appears to be a generally safe and successful bariatric procedure.
