Abstract
In this study we evaluated a recently introduced method of treatment of chronic_anal fissure (medically using Diltiazem 2o/o twice daily) versus a standard, previously evaluated and universally accepted method of treatment (surgically by open lateral internal sphincterotomy).Forty patients were included in this study and were divided randomly into two groups.
