Resumo Introdução
SASI is a metabolic surgery that has recently gained renewed attention,it employs an omega loop for single-anastomosis intestinal bipartition.SASI offers potential advantages,including access to the biliary tree and duodenum,reduced risk of nutritional deficiencies,and avoidance of excluded gastrointestinal segments.This report presents our initial outcomes ofSASI.
Resumo Métodos
We retrospectively analyzed data from46 patients who underwentSASI between September2024andJuly2025,evaluating their treatment outcomes.
Resumo Resultados
Of the46 patients,most were female (n=33;71.7%) with a mean age of39years.Mean preoperative BMI was51,4±6,2kg/m2.Revisional operations accounted for19,6%(n=9)of procedures,predominantly in patients with prior gastric sleeve surgery (n=8,88,9%).2 cases of iatrogenic organ perforation occurred intraoperatively,but without significant impact.Most patients were discharged on postoperative day2 (n=42,91,3%).Early postoperative complications included 3surgical site infections and 1case of AKI requiring readmission.At 6months postoperative(n=15),overall mean total weight loss was21,7%,while in primary cases was25% and in revisional procedures was13%.To date,no clinical or laboratory evidence of significant nutritionaldeficiencies has been observed in any case.
Resumo Discussão
Our initial experience withSASIdemonstrates its safety and positive short-term outcomes,consistent with existing literature.Continued long-termfollow-up is crucial for understanding future challenges and optimizing bariatric results.
