Endoscopic monopolar coagulation of internal haemorrhoids: a surgeon's experience of the first 100 cases

The purpose of this study was to evaluate one surgeon's initial experience with a novel technique of retroflexed endoscopic coagulation of internal haemorrhoids.

Patients who presented with symptoms and signs indicating Grade II-III haemorrhoids were counselled before the procedure. Those who were assessed to require an examination of their colon, based on their age and symptoms, underwent a full colonoscopy before treatment of the haemorrhoids. After the procedure, patients were routinely prescribed nonsteroidal anti-inflammatory drugs, antibiotics and laxatives.

The first 100 patients of median age 52.0 (20.8-78.5) years included 65 (65%) women. Five (5%) patients suffered from postprocedural complications, of which three (3%) were postprocedural bleeding and two (2%) were postprocedural pain, all treated conservatively. The recurrence rate was 6% at a median follow-up time of 36 (6-76) months. The median duration of follow-up was 36.5 (8.5-57.0) months.

This novel technique appears to be safe and effective for the treatment of Grade II-III internal haemorrhoids, and can be incorporated seamlessly into the end of a colonoscopy for the evaluation of haematochezia. Comparative trials should be performed.
