Evaluation of argon plasma coagulation in healing of a solitary rectal ulcer in comparison with conventional therapy: a randomised controlled trial.

Introduction: Argon plasma coagulation (APC) has been reported to be effective in the treatment of solitary rectal ulcer syndrome (SRUS). However, it has not appeared to be effective in healing ulcers.

Aim: This study aimed at assessing the effectiveness of APC in controlling rectal ulcer-induced bleeding, and at examining the ultimate effect of this approach in healing these lesions.
