Abstract

Background

One-anastomosis gastric bypass (OAGB) is an effective bariatric procedure that confers satisfactory weight loss and improvement in comorbidities. The present study aimed to compare OAGB with fixed bypass of the proximal 200 cm of small bowel and tailored bypass of the proximal 1/3 of bowel.

Methods

Patients with class II/III obesity underwent OAGB with either fixed bypass of the proximal two meters or tailored bypass of the proximal 1/3 of bowel. The main outcomes of the study were weight loss, improvement in comorbidities, complications, and changes in nutritional parameters after each technique.

Results

The present study included 80 patients (62 female) of a mean age of 41 years and mean body mass index (BMI) of 50.9 kg/m2. The tailored bypass group was followed by a significantly lower BMI and significantly higher excess weight loss and total weight loss at 6 and 12 months postoperatively. There was no significant difference between the two groups in terms of improvement in comorbidities. The fixed bypass group was associated with a significantly higher complication rate than the tailored bypass group (22.5 vs. 5%, P = 0.04). Both groups were associated with similar changes in the nutritional parameters at 12 months postoperatively, except for the higher serum albumin levels after the tailored bypass than the fixed bypass.

Conclusions

OAGB with tailored bypass of the proximal one-third of bowel was associated with greater weight loss and comparable improvement in comorbidities as compared to fixed bypass of the proximal two meters of intestine.
