We report a new procedure that was local resection of the colonic tumor using a colonoscopy in the operation. We called it Colonoscopy-assisted Operation. This method was started at Kin-Ikyo Central Hospital in February 1995. The indications for this procedure are a benign colonic tumor, carcinoma in situ and carcinoma which minutely invaded the submucosal layer. Additionally, this method was adapted to cases in which polypectomy (mucosal resection) by colonoscopy was difficult or not successful. The most remarkable points of this procedure were as follows: first, the site of the skin incision was just above the lesion and its scar was very small: second, the distance to the lesion was very short by colonoscopy: third, pneumoperitoneum was not necessary. The benefits of this method were less surgical stress than the conventional operation and shorter operating time than the laparoscopic operation, and enyone can do this operation very easily. It is suggested that this procedure is a reasonable method for adaptation to colonic non-invasive tumors.
