caiman versus ligasure hemorrhoidectomy. Postoperative pain, early complications, long-term follow-up, and costs
Purpose. Recently, the use of radiofrequency for hemorrhoidectomy has minimized incidence of postoperative complications. Effectiveness of LigaSure is demonstrated, but it is quite expensive. This study aims to compare LigaSure with Caiman, a cheaper instrument that uses radiofrequency for hemorrhoidectomy. Methods. A total of 35 patients were enrolled in this study between January 2015 and December 2017: 35 (Group A: Caiman) patients were matched with 35 control patients (Group B) from our historical cohort, treated with LigaSure.
