背景和目的：刷检细胞学对诊断胆管狭窄很有用。关于乳头周围胆总管远端的胆管狭窄刷检，内镜逆行胰胆管造影术后胰腺炎的风险尚不清楚。我们的研究旨在评估后内镜逆行胰胆管造影胰腺炎的风险，通过使用此procedure.Methods：共150例内镜逆行胰胆管造影初治患者接受内镜逆行胰胆管造影术，包括胆管狭窄刷回顾性分析。将患者分为乳头周围组（n=25）和非乳头周围组（n=125）。主要结局是内镜逆行胰胆管造影术后胰腺炎的发生率。我们分析了内镜逆行胰胆管造影术后胰腺炎的风险，采用基于倾向评分的治疗加权逆概率来调整选择偏倚。内镜逆行胰胆管造影术后胰腺炎的总发生率为11.3%，内镜逆行胰胆管造影术后乳头周围胰腺炎的发生率明显高于其他组（32.0% vs 7.2%，p
Background and aims: Brushing cytology is useful for diagnosing biliary strictures. With regard to biliary stricture brushing at the distal common bile duct in the surrounding of the papilla, the risk of post-endoscopic retrograde cholangiopancreatography pancreatitis is unknown. Our study aimed to evaluate the risk of post-endoscopic retrograde cholangiopancreatography pancreatitis by using this procedure.Methods: A total of 150 endoscopic retrograde cholangiopancreatography-naive patients undergoing endoscopic retrograde cholangiopancreatography including biliary stricture brushing were retrospectively analyzed. Patients were divided into two groups: the surrounding of the papilla group (n=25) and the other group (n=125). The primary outcome was the post-endoscopic retrograde cholangiopancreatography pancreatitis incidence. We analyzed the risk of post-endoscopic retrograde cholangiopancreatography pancreatitis by using inverse probability of treatment weighting based on propensity scores to adjust for selection bias.Results: The overall incidence of post-endoscopic retrograde cholangiopancreatography pancreatitis was 11.3%, and post-endoscopic retrograde cholangiopancreatography pancreatitis of the surrounding of the papilla group occurred significantly more frequently than in the other group (32.0% vs 7.2%, p
