Single Anastomosis Sleeve Jejunal Bypass (SASJ) Versus Roux-en-Y Gastric Bypass in Patients with Obesity

Obesity and its related morbidities has become a great concern worldwide. Bariatric surgery, regardless of its type, is the most effective approach for morbid obesity treatment. Single anastomosis sleeve jejunal (SASJ) bypass is a novel technique of bariatric surgery that can be considered for patients with previous history of severe gastroesophageal symptoms. The current study aimed to compare outcomes of SASJ with classic gastric bypass in a six-month follow-up.

This was a cohort study conducted on 50 patients underwent two types of bariatric surgeries (Classic Roux en-Y and SASJ), each contained 25 cases, during the years 2017 and 2018. Patients' information including age, gender, height, basal weight, body mass index (BMI), serum albumin, and glycated hemoglobin (HbA1C) were recorded and compared basically and within one, three and six months after surgery.

Members of two groups were similar regarding age, gender distribution, height, basic BMI, HbA1C, albumin, and excess weight (P > 0.050 for all). Both the groups significantly lost weight within six months; while comparison of them showed no statistical difference regarding excess weight loss, BMI, HbA1C, and albumin (P > 0.050 for all). Within six months, the mean excess weight loss was 54.54 in SASJ and 50.54 in the other group.

Trend of weight loss following SASJ bypass was similar to classic gastric bypass. Therefore, due to reversibility and easier gastric follow-up studies in SASJ approach, this technique can be considered for cases with particular indications. Further studies with longer follow-ups are strongly recommended.
