Postoperative Anal Stenoses with Ligasure Hemorrhoidectomy

Haemorrhoidectomy with Ligasure™vs conventional excisional techniques: meta‐analysis of randomized controlled trials

“…However, recent reports of anal injuries suggest that LigaSureÔ haemorrhoidectomy is not without complications [35][36][37][38]. It was suggested that cauterizing would contribute to anal stenosis from thermal or electric injury [39]. In our analysis, anal stenosis and haemorrhoid relapse incidence were significantly lower in Ligasure group than in other excisional treatments (P = 0.024).…”

Haemorrhoidectomy by vessel sealing system under local anaesthesia in an outpatient setting: preliminary experience

“…[28] reported a 6% rate of stenosis requiring dilation [28]. Significant heat production generated by the larger surface area of the LigaSure TM jaws may lead to tissue damage with subsequent scarring responsible for this complication [29,30]. Symptomatic anal stenosis did not occur in our series and this may be related to the use of local anaesthesia.…”

Ligasure™ vs . Conventional Diathermy in Excisional Hemorrhoidectomy: A Prospective, Randomized Study

“…Postoperative anal stenosis with the Ligasure™ hemorrhoidectomy was reported in 1 of 42 patients (2.4 percent) by Wang et al 13 Ramcharan and Hunt 15 reported the same complication in 1 of 25 patients (4 percent) and have attributed this complication to scalding of the anal margin and/or perianal skin. Gravante and Venditti, 16 who encountered the same complication in 4 of 203 patients (2 percent), recommended that to avoid this complication the perianal and mucocutaneous bridges should be protected by incising the anorectal margin with the cold knife first and then retracting the cutaneous margin from the bipolar blades before the sealing cycle begins. The operative technique adopted in the present study for Ligasure™ hemorrhoidectomy entailed application of the bipolar blades to the perianal skin for several reasons.…”
