Single-Anastomosis Sleeve Jejunal (SAS-J) Bypass as Revisional Surgery After Primary Restrictive Bariatric Procedures

Purpose: Single-anastomosis sleeve jejunal (SAS-J) bypass is the modification of a single-anastomosis sleeve ileal (SASI) bypass with a short biliary limb. SAS-J bypass is reported to be a good primary bariatric procedure. This study aimed to evaluate the results of SAS-J bypass as a revisional surgery after failed primary restrictive bariatric procedures.

Material and methods: This was a prospective cohort study including 43 patients who underwent SAS-J bypass as a revisional surgery for weight regain after laparoscopic sleeve gastrectomy (LSG), laparoscopic adjustable gastric band (LAGB), or laparoscopic gastric plication.

Results: Of the total patients, 35 (81.4%) were female, and 8 (18.6%) were male. The mean BMI was 46.3 kg/m². The mean age was 41 years. Thirty-two patients (74.4%) had a failed sleeve, 9 (20.9%) had a failed LAGB, and 2 (4.7%) had a failed gastric plication. The mean operative time was 104 min. Intra-abdominal bleeding occurred in 1 case (2.3%), and intraluminal bleeding occurred in 3 cases (7%). No case (0%) developed a leak. The percentage of excess weight loss (%EWL) reached 76.5% after 1 year. Type 2 diabetes mellitus remission occurred in all diabetic patients, hypertension remitted in 80%, hyperlipidemia remitted in 83.3%, and obstructive sleep apnea syndrome improved in all cases. Gastroesophageal reflux disease (GERD) symptoms were improved in 86.7% of patients. Significant biliary gastritis occurred in 4 patients (9.3%). Dumping syndrome was reported in 4 patients (9.3%).

Conclusions: SAS-J bypass was effective as a salvage surgery after failed restrictive bariatric procedures, but long-term follow-up is needed.
