The authors performed a meta-analysis of randomized controlled trials comparing short-term outcomes in LigaSure and conventional hemorrhoidectomy. They found that operative time, blood loss, and pain on postoperative day 1 were significantly less following LigaSure hemorrhoidectomy than conventional hemorrhoidectomy. For minor procedures, blood loss is realistically not a significant factor and the difference in operative times is also not clinically significant. Pain, however, remains an important issue.
