Introduction
The aim of this study was to compare the outcomes between the LigaSure vessel sealing system and the conventional closed Ferguson hemorrhoidectomy procedure performed by diathermy.
Methods
A series of 84 patients with grades III and IV hemorrhoids were randomized into two groups: (1) LigaSure hemorrhoidectomy with submucosal dissection (42 patients) and (2) Ferguson hemorrhoidectomy (42 patients). The patient demographics, operative details, parenteral analgesic requirement, postoperative pain score (assessed by an independent assessor), operating time, intraoperative blood loss, hospital stay, early and delayed complications, and time off from work or normal activity were recorded. The patients were regularly followed up at 1, 2, 4, 6, and 8 weeks after surgery.
Results
There were no statistically significant differences between the two groups in terms of age, gender, duration of symptoms, grade of the hemorrhoid(s), or number of hemorrhoids resected. The mean operating time for LigaSure hemorrhoidectomy with submucosal dissection was significantly shorter than that for the Ferguson hemorrhoidectomy (11.3 ± 0.4 vs. 34.2 ± 0.7 minutes; P < 0.0001). Patients treated with the LigaSure method had significantly less blood loss (P < 0.0001), a better pain score (P < 0.0001), less parenteral analgesic requirement (P < 0.0001), shorter hospital stay (P < 0.0001), and less time off from work or normal activity (P < 0.0001). There was no difference in the early and delayed postoperative complications between the two groups.
Conclusions
LigaSure hemorrhoidectomy with submucosal dissection is a safe, effective procedure for grade III and IV hemorrhoids. Patients derive greater short-term benefits: reduced intraoperative blood loss, operating time, and postoperative pain as well as earlier resumption of work or normal activity. Long-term follow-up with a larger number of patients is required to confirm the long-term results of this procedure.
