Background
The aim of the study was to compare the results in 95 patients randomly allocated to undergo either stapled or open hemorrhoidectomy using Ligasure.
Methods
Ninety-five patients with grade III and IV hemorrhoids were randomly allocated to undergo either stapled (50 patients) or open using Ligasure (45 patients). Stapled hemorrhoidectomy was performed with the use of a circular stapling device. Open hemorrhoidectomy was accomplished according to the Milligan-Morgan technique by using Ligasure. Postoperative pain was assessed by means of a visual analog scale (VAS). Recovery evaluation included return to pain-free defecation and normal activities. A 6-month clinical follow-up and an 18 (12-24) month median telephone follow-up were obtained in all patients.
Results
Operation time for open hemorrhoidectomy using Ligasure was shorter [median 13 (range 9.2-16.1) min vs 15 (range 8-17) minutes, p < 0.05]. Median range of VAS score in the stapled group were significantly lower [VAS score after 8 h: 3 (2-6) vs 5 (3-8), p < 0.01; VAS score after first defecation: 5 (3-8) vs 7 (3-9), p < 0.001. The stapled hemorrhoidectomy was associated with an increased incidence of intraoperative bleeding in 18 cases (36%) vs four cases (8.8%) of the Ligasure group. There were three cases (6%) from the stapled group with recurrence of the hemorrhoids and none from the open technique.
Conclusions
Hemorrhoidectomy with a circular stapler device is easy to perform, but one more line of clips must be added to the device to avoid intraoperative bleeding from the cut line. Hemorrhoidectomy performed using Ligasure is more painful postoperatively but is a more radical operation.
