The present study aimed to compare the outcome of single anastomosis sleeve ileal (SASI) bypass and sleeve gastrectomy (SG) in regards weight loss, improvement in comorbidities at 12 months of follow-up, and postoperative complications. This was a case-matched, multicenter analysis of the outcome of patients who underwent SG or SASI bypass. Patients who underwent SASI bypass were matched with an equal number of patients who underwent SG in terms of age, sex, BMI, and comorbidities. The main outcome measures were excess weight loss (EWL) at 6 and 12 months after surgery, improvement in medical comorbidities, and complications. A total of 116 patients (97 female) of a mean age of 35.8 years were included. Fifty-eight patients underwent SASI bypass and an equal number underwent SG. %EWL at 6 months postoperatively was similar between the two groups. SASI bypass conferred significantly higher %EWL at 12 months than SG (72.6 Vs 60.4, p < 0.0001). Improvement in type 2 diabetes mellitus (T2DM) and gastroesophageal reflux disease (GERD) after SASI bypass was better than SG (95.8% Vs 70% and 85.7% Vs 18.2%, respectively). SASI bypass required longer operation time than SG (108.7 Vs 92.8 min, p < 0.0001). Complications occurred in 12 (20.7%) patients after SG and 4 (6.9%) patients after SASI bypass (p = 0.056). The %EWL at 12 months after SASI bypass was significantly higher than after SG. SASI bypass conferred better improvement in T2DM and GERD than SG. Both procedures had similar weight loss at 6 months postoperatively and comparable complication rates.

Single anastomosis sleeve ileal (SASI) bypass versus sleeve gastrectomy: a case-matched multicenter study

BACKGROUND Morbid obesity has been recognized as a public health crisis, particularly in developed countries. Single anastomosis sleeve ileal (SASI) bypass has been introduced as a novel bariatric and metabolic procedure. The present study aimed to describe the technical steps and assess the short-term outcomes of SASI bypass in patients with super morbid obesity. PATIENTS AND METHODS Adult patients of both sexes with body mass index (BMI) ≥50 kg/m underwent SASI bypass and were followed for 12 months postoperatively. Changes in BMI, excess weight loss (EWL), and improvement in comorbidities were recorded on follow-up. RESULTS Twenty patients (17 female) of the mean age of 35.4 years were included in the study. The mean preoperative BMI (53.7±5.9) showed a significant decrease at 6 months (39.9±5.2) and then at 12 months (33.6±6) postoperatively. The mean %EWL was 44.3±7.8 at 6 months and 65.2±12.6 at 12 months. All patients with diabetes mellitus, osteoarthritis, and reflux esophagitis showed resolution at 12 months after the SASI bypass. Complications were recorded in 2 patients and no mortality was reported. CONCLUSIONS SASI bypass is an effective and safe bariatric procedure that confers significant loss of weight and improvement in medical comorbidities. As compared with previous studies on patients with lower BMI, patients with super morbid obesity attained lower %EWL but similar resolution of diabetes mellitus at 12 months after SASI bypass.

Laparoscopic Single Anastomosis Sleeve Ileal (SASI) Bypass for Patients With Morbid Obesity: Technical Description and Short-term Outcomes.

Is transit bipartition a better alternative to biliopancreatic diversion with duodenal switch for superobesity? Comparison of the early results of both procedures.

Single-anastomosis sleeve ileal (SASI) bypass is a simplification of sleeve gastrectomy with transit bipartition. Both share a metabolic foundation through early postprandial ileal brake, and SASI bypass has the advantages of shorter operative time and less incidence of internal herniation. This study evaluates the safety and outcome of SASI bypass with 2-year follow-up. A retrospective cohort study of all patients who underwent SASI bypass in the period between June 2016 and January 2019. The primary outcome was weight loss and diabetic remission. Three hundred twenty-two patients underwent SASI bypass with a mean age of 37.4 ± 15 years and a mean body mass index of 50.1 ± 7.7 kg/m2. Thirteen patients (4%) had early major postoperative complications. The 1-year percentage of excess weight loss (%EWL) was 86.9 ± 9.2, and diabetic remission rate was 98.2%. The 2-year %EWL was 96.7 ± 5, and diabetic remission rate was 97.9%. Twenty-six patients had gastroesophageal reflux that improved in 21 (80.7%) patients, remained stationary in 4 (15.4%) patients, and worsened in one patient who required reversal. One patient (0.3%) had severe protein-energy malnutrition and is prepared for reversal. Technical variations had no significant impact on %EWL or diabetic remission. SASI bypass had a promising outcome in terms of 2-year %EWL, diabetic remission, and improvement of preoperative GERD. However, stationary or progressive course of GERD is a substantial possibility. Although the double-outlet for the gastric content allows duodenal access, it may be an obstacle to the standardization of postoperative care. The double-outlet is not a guarantee for absence of malnutrition.
