BACKGROUND: One-Anastomosis Gastric Bypass (OAGB) is becoming popular, but some patients may need to convert to Roux-en-Y Gastric Bypass (RYGB) due weight-related difficulties or postoperative complications. The data on conversions is currently limited to 30-day or short-term follow-up studies. As such, the objective of this study was to evaluate the indications and mid-term outcomes for OAGB conversions to RYGB at a tertiary referral center in the United Arab Emirates.
METHODS: A retrospective analysis was conducted on patients who underwent conversion from OAGB to RYGB between February 2016 and May 2023. Demographic information, indications for conversion, intraoperative details, and mid-term outcomes were collected and analyzed.
RESULTS: Sixty-four patients underwent conversion from previous OAGB to RYGB. The cohort was 73.4% female (n = 47) with a mean age of 40.8 years. Indications for conversion included acid reflux (n = 28, 43.7%), intractable nausea/vomiting (n = 20, 31.2%), protein-calorie malnutrition (n = 7, 10.9%), anastomotic ulcer (n = 6, 9.3%) and weight recidivism (n = 3, 4.7%). The mean operative time was 238 ± 78.3 min. During the procedure, three intraoperative complications occurred: two cases of bleeding and one case of bowel perforation; all successfully addressed during surgery. The median hospital stay was 3 ± 15.8 days. Three patients (4.6%) experienced major postoperative complications comprising 2 anastomotic leaks and 1 small bowel obstruction. The mean follow-up time was 26.2 ± 19.7 months, with 96.2% of patients reporting resolution of symptoms. There were no mortalities.
CONCLUSIONS: Acid reflux is representing 43.7% of the indications for conversion from OAGB to RYGB. The symptom resolution rate holds significance, standing at a remarkable 96.8%. Despite surgical technique advancements, the complication rate after conversions remains significant at 4.6%, with no mortality reported. OAGB patients should be informed about these risks prior to undergoing conversions from OAGB to RYGB.
