Prospective, randomized trial comparing pain and complications between diathermy and scissors for closed hemorrhoidectomy.
OBJECTIVE
The aim of this study was to assess pain and complication rates after closed hemorrhoidectomy with the use of either scissors or diathermy excision.


METHODS
Ninety-one consecutive patients were prospectively randomly assigned by use of sealed envelopes to Group A (diathermy dissection; n = 44) or Group B (scissors dissection; n = 47). The resulting hemorrhoidal pedicle after hemorrhoidal dissection was transfixed and buried under the mucosa, which was closed with 3-0 chromic catgut.


RESULTS
The median time taken for surgery was ten minutes in both groups. The range for Group A was 5 to 25 minutes, and the range for Group B was 5 to 20 minutes. There were no statistically significant differences in the pain scores between the two groups for any of the seven postoperative days studied. The median number of pethidine injections in Group A was 1 and in Group B was 0 (P < 0.009). The number of oral analgesic tablets used was 8 (range, 4-10) and 14 (range, 0-10) for Groups A and B, respectively (P < 0.001). The number of tubes of topical lignocaine jelly used was 14 (range, 0-22) and 14 (range, 7-88) in Groups A and B, respectively. Two patients in each group developed secondary hemorrhage, but no patient had anal stricturing.


CONCLUSIONS
No excessive complications are seen with closed hemorrhoidectomy, and diathermy seems to require less postoperative analgesic medicine than scissors for closed hemorrhoidectomy except in the first 24 hours.
