title: Stapling procedure for haemorrhoids versus Milligan-Morgan haemorrhoidectomy: randomised controlled trial.
abstract: BACKGROUND
  Surgical haemorrhoidectomy has a reputation for being a painful procedure for a fairly benign disorder. The circular transanal stapled technique for the treatment of haemorrhoids has the potential to offer a less painful rectal procedure in place of ablative perianal surgery. We compared the short-term outcome of the circular stapled procedure for haemorrhoids with current standard surgery in a randomised controlled trial.
  
  
  METHODS
  40 patients admitted for surgical treatment of prolapsing haemorrhoids were randomly assigned to Milligan-Morgan haemorrhoidectomy (n=20) or the circular stapled procedure. Under general anaesthesia patients underwent standardised diathermy excision haemorrhoidectomy or had a circumferential doughnut of rectal mucosa and submucosa above the dentate line excised and closed with a standard circular end-to-end stapling device. All patients received standardised preoperative and postoperative analgesic and laxative regimens. Patients completed linear analogue pain charts each day and were interviewed at 1, 3, and 6-10 weeks postoperatively. Summary measures of average pain experience were calculated from 10 cm linear analogue pain scores and were used as the primary outcome measure.
  
  
  RESULTS
  The stapled group had shorter anaesthesia time (median 18 [range 9-25] vs 22 [15-35] mins). Average pain in the stapled group was significantly lower than it was in the Milligan-Morgan group (2.1 [0.2-7.6] vs 6.5 [3.1-8.5], 95.1% CI difference medians 1.9-4.7, p<0.0001. Mann-Whitney U test). Average pain relative to what the patient expected was also significantly less in the stapled group (-2.8 [-4.4 to 1.3] vs 0.7 [-1.8 to 3.4]. Hospital stay and time to first bowel motion were not significantly different between groups. Return to normal activity was significantly shorter in the stapled group (17 [3-60] vs 34 [14-90]. Early and late complications, patient-assessed symptom control, and functional outcome appear similar after short-term follow-up.
  
  
  CONCLUSIONS
  The circular stapled technique offers a significantly less painful alternative to Milligan-Morgan haemorrhoidectomy and is associated with an earlier return to normal activity. Early symptom control and functional outcome appear similar. However, long-term symptomatic and functional outcome need further study.
