The aim of this randomized prospective trial was to compare LigaSure and conventional diathermy haemorrhoidectomy.


Two hundred and eighty‐four patients with grade III or IV haemorrhoids were randomized to LigaSure or diathermy (Milligan–Morgan) haemorrhoidectomy as a day‐case procedure. Operating time, postoperative pain score, hospital stay, postoperative complications, wound healing time and time to return to normal activities were assessed. Thirty‐four patients were lost to follow‐up.


The mean operating time for LigaSure haemorrhoidectomy was significantly shorter than that for diathermy (P = 0·011). Patients treated with LigaSure had significantly less postoperative pain (measured on a visual analogue scale; P = 0·010), a shorter wound healing time (defined as time to absence of swelling; P = 0·012) and less time off work (P = 0·010) than patients who had diathermy. Neither postoperative complications nor mean hospital stay (day‐case surgery) were significantly different.


LigaSure haemorrhoidectomy demonstrates simplicity, reproducibility, a low complication rate, fast wound healing, a quick return to work and reduced postoperative pain. Copyright © 2007 British Journal of Surgery Society Ltd. Published by John Wiley & Sons, Ltd.
