Abstract
The use of intraoperative colonoscopy has increased alongside progress in the development of colonoscopy-associated devices and techniques, including the colonoscope itself. In the present review, we focus on four circumstances in which intraoperative colonoscopy is beneficial to colorectal surgery: (i) intraoperative determination of a tumor's location; (ii) observation of the proximal colon in cases of obstructive colorectal cancer; (iii) confirmation of the integrity of anastomosis; and (iv) novel surgical techniques that combine laparoscopic and endoscopic surgery. In light of the findings of our review, a combination of colonoscopy and surgery-especially laparoscopic surgery-is expected to facilitate the optimal handling of a variety of colorectal tumors, ranging from benign cases to advanced and obstructive cases.
