Background and Study Aims: It is difficult, dangerous, and time consuming to resect colorectal polyps situated behind the semilunar folds. The aim of this study was to examine the efficacy of a distal attachment in the endoscopic resection of these polyps.

Patients and Methods: The study group consisted of 11 patients, each with a colorectal polyp situated behind a semilunar fold, and of which the base was invisible without the use of a distal attachment. With the attachment fitted to the distal end of the endoscope, we pressed the semilunar fold situated at the anal side of the polyp so that the polyp, including its base, could be brought within the visual field. Maintaing the optimal position, we snared, ligated, and resected all polyps by electrocautery.

Results: The polyps were of sessile type in eight patients and pendunculated type in three, with a diameter ranging from 7 to 18 mm (mean 11 mm). Although the base of the polyp was invisible under conventional observation, pressing the fold brought good visualization. The optimal position for snaring the polyp was secured by fine endoscopic adjustment, and the polyps were easily resected in all patients.

Conclusion: We conclude that the distal attachment is a simple but very valuable tool in the endoscopic resection of colorectal polyps situated behind the semilunar folds, and recommend its routine use in both diagnostic and therapeutic colonoscopy.
