Project description:BackgroundPeriampullary diverticula (PAD) often detected during endoscopic retrograde cholangiopancreatography (ERCP), and ERCP remains the primary approach to treating bile duct stones, and papilla cannulation plays a critical role in the success of ERCP. PAD can reduce the cannulation success rate. Needle knife precut greatly promoted the clinical application of precut incision. However, this approach also increases the risk of various adverse events. The present study aimed to compare the perioperative outcomes of pancreatic duct guide wire-assisted needle knife precut and conventional needle knife precut for PAD with difficult cannulation.MethodsA total of 230 cases of PAD with difficult cannulation of the duodenal papilla diagnosed by ERCP between June 2009 and December 2021 were retrospectively reviewed. The exclusion criteria were set as follows: patients with ERCP history, coagulopathy prothrombin time two times longer or platelet (PLT) count ≤70×109/L, or an inability to tolerate endoscopy due to severe heart/lung diseases. Pancreatic duct guide wire-assisted needle knife precut (Group A) was performed in 135 cases, and conventional needle knife precut (Group B) was performed in 95 cases. All clinical data were analyzed retrospectively. SPSS20.0 statistical software was used for the t-test and analysis of variance. P<0.05 was considered statistically significant.ResultsThe operating time of the needle knife precut was significantly shorter in Group A (18.44±6.65 min) compared with Group B (32.05±13.15 min, P<0.01). Moreover, the success rate of the cannulation was markedly higher in Group A (100%, 135/135) compared with Group B (78.9%, 75/95). Intraoperative complications occurred in 15 (11.1%) and 26 (27.4%) cases in Groups A and B, respectively (P<0.01). Postoperative complications occurred in 10 (7.4%) and 17 (17.9%) cases in Groups A and B, respectively (P<0.01). Our results showed notable differences in the operating time, success rate of cannulation, intraoperative complication rates, and postoperative complication rates between the two approaches.ConclusionsPancreatic duct guide wire-assisted needle knife precut appeared to be a safe and effective modality for PAD with difficult cannulation in the duodenal papilla.
