[Ligature and excision method with diathermy for haemorrhoidectomy: in comparison with conventional method].

The usefulness of ligature and excision method with diathermy (group D) for haemorrhoidectomy was evaluated in comparison with conventional ligature and excision method with scalpel and scissors (group S) from several parameters. Intraoperative bloodloss and hospitalization days in group D were significantly smaller than those in group S. Moreover, post-operative woundal bleeding and edema in group D were significantly smaller than those in group S. As regards post-operative pain, although there were no significant differences between the two groups, the values in group D were slightly improved as compared with group S. These results indicate the usefulness of diathermic method for haemorrhoidectomy because of its better cost-efficacy as compared with conventional method with scalpel and scissors.
