Brief Summary

Lateral internal sphinterotomy (LIS) is the gold standard against which all treatments are compared with a healing rate over 92%. However, the most serious complication of this procedure is anal incontinence. To overcome these problems, continued efforts are being tried to find less invasive treatments modalities for anal fissure that is as effective as surgical therapy with lower morbidity.

Study Arms (2)

LIS group

ACTIVE COMPARATOR

Lateral internal shincterotomy: A blade knife (No 11) was inserted between internal and external sphincter. The tip of the blade was angled medially pointing just above the dentate line and IS was divided. When the knife was felt beneath the intact mucosa, it was withdrawn.

Procedure: lateral internal sphincterotomy

TENS group

ACTIVE COMPARATOR

Posterior tibial nerve stimulation by transcutaneous electrical nerve stimulation by through a stimulating TENS unit.

Procedure: TENS

Interventions

TENSPROCEDURE
