Anal stretch has a higher risk of fissure persistence than internal sphincterotomy and also a significantly higher risk of minor incontinence than sphincterotomy .
The combined results of open versus closed partial lateral internal sphincterotomy show little difference between the two procedures both in fissure persistence and risk of incontinence .

These reports are either subject to selection bias ( in non-r and omized studies ) or observer bias ( in all studies ) or have inadequate numbers of patients enrolled to answer the question of efficacy .

Anal sphincter function after treatment of fissure-in-ano by lateral subcutaneous sphincterotomy versus anal dilatation
Twenty patients with chronic anal fissure were r and omized into two groups . Ten patients were treated with lateral subcutaneous sphincterotomy and 10 with anal dilatation . Anal dilatation was carried out preoperatively , and at 1 and 3 months after the operation in all patients . Preoperatively there was a significantly increased maximal resting pressure in the 20 fissure patients ( 80 mmHg median ) compared with 20 control subjects ( 50 mmHg median ) . Postoperatively a significant decrease in pressure occurred in the dilated group ( 49 mmHg medianp<0.05 ) , whereas the pressure was not significantly reduced in the group that underwent sphincterotomy ( 65 mmHg medianp<0.05 ) . At 1 year three patients complained of recurrent symptoms of anal fissure in the dilated group compared with one in the sphincterotomy group . Minor continence disturbance was noted in two patients in both groups
