RESUMEN
Background: Anal fissures are often encountered in surgical practice with surgery the gold standard management for chronic anal fissures. Recently the widespread use of pharmacologic agents for chronic fissures has increased. In our study we compare topical 2% diltiazem with lateral sphincterotomy with respect to symptoms such as relief of pain, ulcer healing, and side effects of treatments.Methods: A prospective comparative study, a total of 80 patients were randomized into 2 groups 40 each. Group A patients were subjected to open internal lateral sphincterotomy and group B to 2% topical diltiazem. The patients in both groups were followed up at 1st, 4th, 14th weeks and 6 months in OPD and were assessed for pain, sphincter tone and complications.Results: In group A (lateral anal sphincterotomy), patients achieved a good pain relief with a mean pain score of 1.98 by one week post procedure whereas group B (2% diltiazem) had taken 14 weeks to achieve similar pain relief (pain score of 1.5). At the end of 6 months, healing of fissure was noted in 100% of group A and in 90% of group B. 4 patients (10%) had recurrences in group B. Flatus incontinence was reported in 2 patients (5%) in group A although transient.Conclusions: Lateral anal sphincterotomy is superior to 2% diltiazem especially in healing of fissure, pain relief, quality of life and recurrence. Pharmacologic agents should be reserved for patients who are unfit or unwilling for surgery or can be used as a bridge therapy till sphincterotomy can be planned.
RESUMEN
Anal fissures are often encountered in surgical practice in both sexes. It is a distressing disease impacting quality of life and causes profound morbidity among those affected. If left untreated, it may lead onto perianal abscess or even malignancy in long standing cases. Surgery is the gold standard management for chronic anal fissures. Recently the widespread use of pharmacologic agents for chronic fissures has increased. The management of chronic anal fissures has migrated to an era of multifaceted approach. This narrative review looks into various studies spanning over a period of 16 years. Various articles were shortlisted and analyzed for efficacy of various treatment methods, their impact in hospital stay, quality of life improvement, recurrence rate and complications among various treatment methods. We concluded from this review, that open lateral internal sphincterotomy is still the gold standard method of treatment for chronic anal fissure. Among pharmacological agents, 2% diltiazem has the best effectiveness with good compliance rate. Modern surgical techniques like VY plasty can be reserved for special situations. We do not recommend the practice of manual anal dilatation.
