The aim of this study was to evaluate the effects of ERCP on LC and to determine appropriate time of LC after ERCP.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Six hundred twenty\u2010one patients who underwent LC for gallstone disease were enrolled. These patients were divided into two groups; patients with preoperative ERCP prior to LC (ERCP group) and patients who underwent LC without ERCP (non\u2010ERCP group). Among these patients, patients who had shown acute cholecystitis or cholangitis were excluded. To control for different demographic factors in the two groups, propensity score case matching was used at a 1:1 ratio. Finally, 142 patients were matched with 71 patients of the ERCP group and 71 patients of the non\u2010ERCP group. Intraoperative inflammation degree, technical difficulty, and postoperative outcome were analyzed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In the ERCP group, the degree of inflammation was severe and operations were more difficult than those of the non\u2010ERCP group. The operation time was longer, and rates of open conversion were higher in the ERCP group. On multivariate analysis, preoperative ERCP was significant factor for difficult operations. The difficulty of operation was not different according to the operation timing after ERCP.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Preoperative ERCP is a significant factor in difficult LC. Therefore, experienced surgeons should perform LC after preoperative ERCP. Since operation difficulty was similar according to the timing of cholecystectomy after ERCP, there is no reason to delay LC after ERCP.<\/jats:p><\/jats:sec>","DOI":"10.1007\/s00268-015-3076-7","type":"journal-article","created":{"date-parts":[[2015,4,16]],"date-time":"2015-04-16T16:58:28Z","timestamp":1429203508000},"page":"2235-2242","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Impact
