title: Ligasure versus stapled hemorrhoidectomy in the treatment of hemorrhoids: a meta-analysis of randomized control trials.
abstract: The aim of this meta-analysis was to compare the outcomes of Ligasure hemorrhoidectomy and stapled hemorrhoidectomy for prolapsed hemorrhoids. Original studies in any language were searched from MEDLINE database, PubMed, Web of science and the Cochrane Library database, and Wangfang database. Randomized control trials that compared Ligasure hemorrhoidectomy with stapled hemorrhoidectomy were identified. Data were extracted independently for each study, and a meta-analysis was performed using fixed and random-effects models. Five trials including 397 patients met the inclusion criteria. Patients treated with Ligasure had a significantly shorter operative time compared with patients who underwent stapler techniques. The recurrence rate was higher in patients who underwent stapled hemorrhoidectomy. No statistically significant differences were observed in postoperative bleeding, urinary retention, difficult defecating, anal fissure, anal stenosis, incontinence, postoperative pain, return to normal activities, and hospital stay. Our meta-analysis shows that Ligasure is an effective instrument for hemorrhoidectomy, which results in shorter operation time and lower recurrence rate.
