The study was registered in the Japanese UMIN Clinical Trials Registry as UMIN000018727 [https://www.umin.ac.jp/ctr/index.htm], and all patients provided their written informed consent before registering in the study. Patients who were ≥ 20 years of age and undergoing laparoscopic colorectal surgery were eligible for this study. The inclusion/exclusion criteria for this study are shown in Table . Methods: This study was a prospective, multi-center, single-arm registry wherein patients who received INTERCEED® in laparoscopic colorectal surgery were registered consecutively (UMIN-CTR 00001872).
