Background: Most surveillance programs for postoperative infection focus on surgical site infections (SSI). However, remote infections, as postoperative infections, are of emerging clinical importance. We investigated the incidence of both SSI and remote infection following colorectal surgery by performing a subanalysis of a multicenter survey after gastrointestinal surgery. Methods: From September 2015 to March 2016, 1724 patients underwent colorectal surgery in 28 affiliated institutions in Japan. We retrospectively recorded patients' age, sex, surgical site, surgical approach, wound classification, performance status at discharge, and postoperative infection status. Results: Postoperative infections occurred in 236 (13.7%) patients; 150 and 86 patients underwent colon and rectal surgeries (postoperative infection incidence: 13.7% and 14.8%), respectively. Laparoscopic surgery was associated with a significantly lower incidence of postoperative infection compared with open surgery for both colon and rectal surgery (p < 0.001). Among all patients with postoperative infections, 211 (89.4%) had single infections, and 25 (10.6%) had multiple infections. SSI and remote infection in patients with single postoperative infections occurred in 143 (60.6%) and 68 (28.8%) patients, respectively. The most common multiple postoperative infections 3 were "incisional and organ/space SSIs", and "organ/space SSI and bacteremia of unknown origin", with three cases each. Conclusions: This study revealed the distribution of the overall prevalence of postoperative infections, including both SSI and remote infections. Considering the substantial influence of remote infections on patients' quality of life and the social burden, prospective periodic surveillance for both SSI and remote infection is necessary for detailed evaluation and prevention.
