Prospective, randomized controlled trial of LigaSure™ versus conventional hemorrhoidectomy for grade III and IV hemorrhoids

Wagih Mommtaz Ghnnam.

Abstract
Background:
Performing hemorrhoidectomy with LigaSure™ vessel sealing system is a rapid and simple new technique. The aim of this study was to evaluate LigaSure™ hemorrhoidectomy (LH) to open hemorrhoidectomy (OH) performed by the conventional diathermy.
Patients and methods:
One hundred and sixteen patients with grades III and IV hemorrhoids were prospectively randomized to either LigaSure™ or open conventional diathermy hemorrhoidectomy. Primary end point was postoperative pain. Secondary end points were operative time, blood loss, complications, need for analgesics and time to achieve complete wound healing.
Results:
The LigaSure™ group achieved a significant reduction in operative time, blood loss, first postoperative day pain score, seventh day pain score and overall pain score. Patients in the LigaSure™ group required less pethidine analgesia on the first postoperative day. Time to achieve complete wound healing were shorter in the LigaSure™ group. There was no difference in postoperative complications.
Conclusion:
LigaSure™ hemorrhoidectomy provides a valid alternative to conventional hemorrhoidectomy. Based on our results, further studies addressing long-term functional results are needed to prove that LigaSure™ hemorrhoidectomy is the ideal method of hemorrhoidectomy for the patients.
