Abstract
Resting anal canal pressure was measured in 15 patients with anal fissure before and after lateral internal sphincterotomy. This pressure was significantly higher in these subjects (mean 95 .+-. 23.08 mm HG) than in the control group (mean 66.10 .+-. 14.28 mm Hg) before surgery (P < 0.005). After surgery, a normal and canal pressure was produced. Anal canal spasm apparently is responsible for chronicity of anal fissures.Keywords
