Anal stricture following haemorrhoidectomy: early diagnosis and treatment.
Anal stricture is an uncommon but well recognized complication following haemorrhoidectomy. Twenty-seven (3.8%) out of 704 (500 elective and 204 emergency) cases of haemorrhoidectomy performed at the Singapore General Hospital over a 24 month period had clinical evidence of anal stricture post-haemorrhoidectomy. Of the 27 cases, 15 had haemorrhoidectomy as an elective procedure while 12 had it performed as an emergency procedure (chi 2 = 3.26, 1 d.f., P > 0.05, not significant). The mean interval between surgery and presentation of anal stricture was 6 weeks (range 3-12 weeks). Eighteen of the patients were managed by anal dilatation in the outpatient clinic combined with bulk laxatives and a local anaesthetic agent. The other nine patients required a minor surgical procedure comprising either a lateral internal sphincterotomy (five) or an anoplasty (four) procedure. All patients were well, following treatment. None of these patients developed a recurrent stricture at follow up 3 months after treatment. It was concluded that although anal stricture following haemorrhoidectomy is rare, it should be detected and treated early in order to avoid pain and suffering, and treatment is usually successful.
