During which period should we avoid cholecystectomy in patients who underwent endoscopic retrograde cholangiopancreatography?

ABSTRACT Objective: To determine the period during which we should avoid cholecystectomy after endoscopic retrograde cholangiopancreatography. Methods: A retrospective analysis of electronic medical charts of 532 patients undergoing endoscopic retrograde cholangiopancreatography, between March 2013 and December 2017. Results: Approximately one-third of patients underwent the procedure between 4 and 30 days after endoscopic retrograde cholangiopancreatography. The conversion rate was 3.8%. The need for abdominal drainage and the finding of biliary tract injury after surgery were observed in 15.1% and 1.9% of patients, respectively. The length of stay was significantly shorter among patients undergoing surgery more than 30 days after endoscopic retrograde cholangiopancreatography. These patients had a median length of stay of one day, whereas the median length of stay in the group undergoing the procedure between 4 and 30 days after endoscopic retrograde cholangiopancreatography was 2 days. Conclusion: The period during which we should avoid cholecystectomy is between 4 and 30 days after endoscopic retrograde cholangiopancreatography.

摘要
研究目的：明确内镜逆行胰胆管造影术（endoscopic retrograde cholangiopancreatography）后应避免行胆囊切除术的时间段。
研究方法：对2013年3月至2017年12月期间接受内镜逆行胰胆管造影术的532例患者的电子病历进行回顾性分析。
研究结果：约三分之一的患者于内镜逆行胰胆管造影术后4~30天内行胆囊切除术。手术中转率为3.8%。15.1%的患者术后需行腹腔引流，1.9%的患者术后发现胆道损伤。内镜逆行胰胆管造影术后30天以上接受胆囊切除术的患者，其住院时长显著更短：该组患者的住院时长中位数为1天，而内镜逆行胰胆管造影术后4~30天内接受胆囊切除术的患者组，其住院时长中位数为2天。
研究结论：应于内镜逆行胰胆管造影术后4~30天内避免行胆囊切除术。
