Is It Absolutely Necessary to Undergo Anal Dilatation After Anal Fissure Surgery?

Postoperative Anal Dilatation for Anal Fissures

Whether anal dilatation is necessary after anal fissure surgery depends on the specific condition of the patient. For simple anal fissures, anal dilatation is generally not required; however, for chronic anal fissures, anal dilatation treatment is necessary. Here are the details:

1. Simple Anal Fissure

Simple anal fissure refers to an ulcer formed after mechanical damage to the skin layer of the anal canal, often caused by long-term constipation or diarrhea. Patients with simple anal fissures typically do not experience anal sphincter spasm, therefore, anal dilatation is not necessary. Treatment involves using potassium permanganate solution for sitz baths as prescribed by the doctor, and applying topical medications such as erythromycin ointment for anti-infective purposes. Additionally, dietary adjustments are crucial to avoid spicy or irritating foods that may exacerbate the condition.

2. Chronic Anal Fissure

Chronic anal fissure involves a full-thickness defect of the anal canal skin, resulting in a chronic ulcer. Due to the frequent presence of anal sphincter spasm in this condition, anal dilatation treatment is required. Two common methods of anal dilatation are manual dilation and mechanical dilation. Manual dilation is suitable for mild cases of chronic anal fissures, while mechanical dilation is more appropriate for severe cases. During anal dilatation treatments, maintaining local cleanliness and hygiene to prevent infections is also important.

The treatment approach for anal fissures varies depending on the type of fissure. Prior to treatment, it is crucial to identify the underlying cause and select the appropriate treatment method under the guidance of a healthcare professional.
