title: Lateral internal anal sphincterotomy for anal fissure: with or without associated anorectal procedures.
abstract: OBJECTIVE
  To confirm or refute the validity of the fear associated with anal sphincterotomy for anal fissure, particularly when performed with other anorectal procedures.
  
  
  METHODS
  Descriptive study.
  
  
  METHODS
  Surgical Wings - Medicare Hospital and Fatima Medical Center, Multan, over a period of 8 years from January 1994 to December 2001.
  
  
  METHODS
  Records of 112 anal fissure patients, 46 (41.0%) males and 66 (58.9%) females, ranging in age from 12-95 years (mean 39) were studied. All patients with acute or chronic anal fissures with or without other anorectal pathologies were included. Seventeen patients who had anal dilatation and 2 recurrent fissures were excluded. Open technique of anal sphincterotomy was employed in all cases. Results were recorded and analyzed.
  
  
  RESULTS
  Fissures were acute in 16 (14.2 %) and chronic in 96 (85.7 %) patients. Anterior fissure was present in 20 (17.8%), posterior in 80 (71.4%), both in 9 (8.0%) and lateral or multiple fissures in 3 (2.6%) cases. Commonest associated pathology was haemorrhoids; encountered in 64 (57.1%) patients. Minor complications, taken together, occurred in 20 (17.8%) patients. Urinary retention was seen in 3 (2.6%) with lateral internal anal sphincterotomy (LIAS), and in 6 (5.3%) where haemorrhoidectomy was added. Haemorrhage in 2 (1.7%), temporary loss of flatus control in 3(2.6%) and soiling of clothes in 2 (1.7%) patients was encountered. No permanent loss of flatus or faecal control and recurrence has been reported to-date.
  
  
  CONCLUSIONS
  Anal sphincterotomy with or without other anorectal procedures can be safely practiced in properly selected patients. Postoperatively, ablution with mild antiseptic added to plain water is adequate in maintaining hygiene to promote healing.
