anal mastoidectomy

Anal mastoidectomy is an operation that restores anal function by removing the enlarged mastoid part. Treatment of diseases: acute mastoiditis Indication Anal mastoid enlargement due to various reasons. Contraindications 1, with systemic diseases, can not tolerate surgery. 2, local infection, not suitable for surgery. Preoperative preparation 1. Regular use of antibiotics before surgery. 2. Clean the intestines before surgery. complication 1. Bleeding: Because the knot is not tight, slipping is caused; the latter occurs about 7 to 10 days after surgery, due to infection at the ligation site. Due to the action of the anal sphincter, the blood flows back into the intestine without going to the anus, so the phenomenon of "staining red dressing" cannot be found clinically. Therefore, this "acute bleeding" is often not easy to find early. 2, stenosis: careful surgical operation and early anal canal expansion can prevent anal canal stenosis. The stenosis can be at the anal rim, the tooth line or the tooth line. Stenosis at the anal margin is mainly due to excessive removal of the skin and mucosa of the anal margin, causing the wound to contract and causing anal stenosis. The scar is often accompanied by an anal fissure, which is caused by tearing during defecation. The use of manual methods and instruments to expand the anus is ineffective, often requiring multiple surgical treatments. 3, urinary retention: urinary retention is the most common complication after anal canal surgery, prevention of urinary retention.
