Sleeve gastrectomy with transit bipartition: a review of the literature

IntroductionObesity has been identified by the World Health Organization (WHO) as a significant global medical, social, and public health issue. Surgery is the most important therapeutic option for severe morbid obesity and metabolic diseases linked to obesity. Sleeve gastrectomy-transit bipartition (SG-TB) and the single anastomosis sleeve ileal (SASI) bypass, a more simplified variation of SG-TB, have recently become popular methods for treating these conditions. The clinical investigations of SG-TB and SASI bypass are included in this review. In order to find papers published up until December 2022, the Pubmed database was searched.Areas coveredWe comprehensively review the most recent research on the use of SG-TB and SASI bypass in clinical practice, including the surgical technique, weight loss, comorbidity remission, post-operative complications, post-operative nutritional status, and the mechanism of operation.Expert OpinionStudies on the SG-TB and SASI bypass have shown positive short-term outcomes. The weight loss and improvement of comorbid conditions with SG-TB and SASI bypass have shown promising results. In comparison to other operations, it has also been demonstrated that there is a relatively low incidence of adverse effects. However, more research is necessary to determine its long-term effectiveness and to address several intriguing issues.
