title: Glyceryl trinitrate ointment did not reduce pain after stapled hemorrhoidectomy: a randomized controlled trial.
abstract: Medications, including topical 0.2% glyceryl trinitrate (GTN), can reduce anal spasm and pain after excisional hemorrhoidectomy. GTN after stapled hemorrhoidopexy was compared with routine postoperative management. Patients with symptomatic grade 3/4 hemorrhoids were recruited. After stapled hemorrhoidopexy, residual perianal skin tags were excised as appropriate. Those requiring double purse-string mucosectomy were excluded. Postoperative pain, pain duration, and complications were assessed. One hundred ten patients (74 men; mean age 50.6 years) were enrolled in the control group and 100 patients (57 men; mean age 49.8 years) in the GTN group. Maximum pain was higher in the GTN group (P  =  0.015). There were no differences between the two groups in residual perianal skin tags requiring excision, postoperative complications, recurrence rates, follow-up period, average pain, duration of pain, or satisfaction scores. Sixteen GTN patients were noncompliant due to side effects. None had persistent perianal skin tags. GTN did not reduce postoperative pain after stapled hemorrhoidectomy.
