Intraoperative Localization Of Right-Sided Small Colonic Lesions: A Novel Use Of The Cholangioscope

Background/Aim: We describe a novel use of the cholangioscope to help in the intraoperative localization of small colonic malignancies on the right side of the colon. Methods: A small incision was made at the base of the appendix and a cholangioscope was inserted into the ascending colon through the incised hole of the appendix. Results: The site of the lesion was precisely determined by palpating the distal end of the cholangioscope while observing the area right under it. Conclusion: Our procedure therefore appears to be worthy of consideration in patients with small colonic lesions on the right side of the colon in whom preoperative endoscopic marking techniques might otherwise be required.
