Recurrence in endoscopic and surgical intervention. Proportions of meta-analyses were calculated and shown as forrest-plots for EA (A), SA (B) and PD (C). Pooled rates of recurrence were calculated to obtain a proportion with a 95% confidence interval (CI). The binary random effects model (DerSimonian–Laird) was used for EA and SA and a fixed effect model with inverse variance weighting was used for PD. EA: endoscopic ampullectomy, SA: surgical ampullectomy, PD: pancreaticoduodenectomy.
