Abstract

is single anastomosis sleeve jejunal bypass (SASJ). Few studies had compared SASJ to other bariatric surgeries. We aimed to compare OAGB to SASJ in weight-loss, reduction in BMI, remission of co-morbidities and operative time.
Methodology: We conducted a prospective non-randomized controlled trial comparing OAGB or SASJ for obesity management. The decision of procedural choice was a shared decision between multidisciplinary team and the patients. Throughout 2019 (January-December) patients were operated and followed for 2 years.
Results: OAGB had a statistically highly significant BMI difference compared to SASJ at 12 months and 24 months p<0.001. However, regarding 3 months BMI difference, no statistical significance was detected between both surgeries, p=0.172. Mean operative time was significantly lesser in OAGB p<0.001 which was statistically highly significant. (79.5%) in OAGB group and (64.7%) in SASJ group had remission of co-morbidities. (20.5%) in OAGB group and (35.3%) in SASJ group had improvement of comorbidities yet, no significant difference between both in remission or improvement of co-morbidities p value=0.250. No statistically significant difference between both groups in post-operative complications.
Conclusion: OAGB and SASJ achieved satisfactory results regarding BMI loss and remission of co-morbidities.
OAGB had less operative time compared to SASJ. OAGB had higher BMI loss at 12 and 24 months but not at 3 months of follow-up. More studies with larger sample size are needed with prolonged follow up to compare SASJ to other bariatric surgeries.
