Objective : To compare the operative time, postoperative complications, and analgesic requirement between
closed hemorrhoidectomy and LigasureTM hemorrhoidectomy.
Materials and 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 (cid:31) 11.76 vs 35.68
(cid:31) 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.
Conclusion : Ligasure hemorrhoidectomy is superior to closed hemorrhoidectomy in terms of reducing the
operative time without affecting postoperative complications.
