Abstract
Background: Metabolic bariatric surgery (MBS) is an effective treatment for obesity and its related comorbidities.1 Publicly funded MBS in New Zealand is regionally limited with variable case volumes, potentially limiting surgical training.2 This retrospective study aims to evaluate if MBS safety and effectiveness are impacted by teaching within a low-volume unit.
Methods: A retrospective outcomes analysis was carried out for all MBS cases of a single surgeon (public and private). Cases were compared based on primary operator status: consultant (COP) and trainee/fellow (TOF). Primary outcomes included multiple safety and effectiveness parameters including leaks, haemorrhage, 30-day morbidity and total weight loss (TWL).
Results: Two-hundred and fifty patients satisfied inclusion criteria. Results are reported as COP and TOF. Primary operator: 87 (34.8%) and 163 (65.2%). There were no leaks, strictures or 30-day mortalities. Perioperative haemorrhage: 1 and 4. Thirty-day morbidity: 1 and 5. One-year TWL: 36.0% and 35.0%. Sleeve stenosis: 0 and 1. Thirty-day readmissions: 1 and 4. One-year readmissions: 4 and 9. Length of stay: 3 and 4 (p=<0.001).
Conclusion: MBS safety and effectiveness outcomes in low-volume practice performed by TOF were no different to COP within our study setting.
