Within 30\u2009days we experienced three complications Clavien\u2010Dindo grade 3 or higher and 13 complications Clavien\u2010Dindo grade 2 or less. Beyond 30\u2009days, interventions were performed for reflux (18 patients), three port\u2010site hernias, two perforated ulcers, and one obstruction secondary to adhesions. Endoscopy was performed for 14 symptomatic gastroenteric anastomotic ulcers and one reflux esophagitis, all managed conservatively. There was no mortality. A total of 159 (60.9%) patients responded to the survey (mean 41.8\u2009months after conversion), with 37.1% reporting significant heartburn and 23.9% reporting significant regurgitation. Nonetheless, 81.8% were happy with the procedure, and 78% would choose it again. Among those with post\u2010cOAGB reflux, enteroenterostomy markedly improved symptoms.

The median percent excess weight loss was 61.1% (IQR 37.7\u201389.5) and mean percent total weight loss was 22.5% (SD 13.3).
