Conditions

Single Anastomosis Sleeve Jejunal Bypass, Sleeve Gastrectomy

Brief summary

The aim of this work is to compare the outcomes of Single Anastomosis Sleeve Jejunal Bypass (SASJ) with sleeve gastrectomy as regards efficacy including sustained weight loss, metabolic syndrome, quality of life, complications and associated comorbidities in morbid obese.

Detailed description

The most commonly performed bariatric surgery worldwide is the vertical sleeve gastrectomy (VSG), the Roux-en-Y gastric bypass (RYGB), and the One anastomosis (Mini) gastric bypass, which has been demonstrated to produce excellent bariatric and metabolic outcomes. Single anastomosis sleeve ileal (SASI) bypass was introduced in 2015 as a modification of Santorini's operation in, as it keeps pass to the duodenum so the biliary tree and the whole gut and can be assessed by the endoscope; there are no blind loops, excluded segments or foreign bodies.

Interventions

Patients underwent single anastomosis sleeve jejunal bypass as a metabolic and weight loss surgery.

PROCEDURELaparoscopic sleeve gastrectomy

Patients underwent laparoscopic sleeve gastrectomy (LGS) as a metabolic and weight loss surgery.

Design outcomes

Primary

MeasureTime frameDescription
Weight loss1 month after the procedureWeight loss was recorded.

Secondary

MeasureTime frameDescription
Metabolic syndrome1 month after the procedureMetabolic syndrome was recorded.
Assessment of quality of life1 month after the procedurequality of life was assessed using specific scoring system is a variation of the BAROS (Bariatric Analysis and Reporting Outcome System). The specific tiers you listed (High, Moderate, and Mild Improvement) * High Improvement excess Weight Loss (%EWL) \>50% + comorbidity resolution + no complications. * Moderate Improvement EWL 30-50% + partial comorbidity resolution. * Mild Improvement EWL \<30% + no major issues.
Incidence of complications1 month after the procedureIncidence of complications such as gastroesophageal reflux disease (GERD), bile reflux, gall stones, reoperations, and postoperative bleeding were recorded.
