Closed vs ligasure hemorrhoidectomy: a prospective, randomized clinical trial.
OBJECTIVE
To compare the operative time, postoperative complications, and analgesic requirement between closed hemorrhoidectomy and Ligasure hemorrhoidectomy.


METHODS
The study was conducted in a prospectively randomized controlled fashion. Forty-seven patients with grade 3 or 4 hemorrhoids plus external component or skin tag were operated on by either hemorrhoidectomy with Ligasure (24 patients) or closed hemorrhoidectomy (23 patients). One patient in each group was lost to follow up. The operative time, postoperative verbal numeric pain score, analgesic requirement, bleeding, and wound dehiscence between the two groups were compared Unpaired t-tests, Mann-Whitney U tests, or Fisher's Exact tests were used where appropriate.


RESULTS
Demographic and clinical data between two groups were comparable. Operative time for the Ligasure hemorrhoidectomy was significantly shorter than the closed hemorrhoidectomy group (21.70 +/- 11.76 vs 35.68 +/- 14.25 min, p < 0. 001), while the number of resected hemorrhoids in the study group were 2.91 versus 2.18 in the control group. However, there were no differences in post-operative pain score, analgesic requirement, bleeding, or wound dehiscence between the two groups.


CONCLUSIONS
Ligasure hemorrhoidectomy is superior to closed hemorrhoidectomy in terms of reducing the operative time without affecting postoperative complications.
