title: [Postoperative anorectal stenosis].
abstract: Stenosis of the rectum after surgery is a rare complication of low anastomosis. Infection, ischemia, foreign body reaction, technical faults or recurrence of neoplasms are the most important causes. Dilatation is attempted either manually or by instrument, if the stenosis causes discomfort and in particular if diarrhea results. Rarely resection of the stenosed segment is necessary. Stenosis in conjunction with incontinence is the most feared complication of anorectal surgery. It develops exceptionally after scarring of a large mucocutaneous defect after hemorrhoidectomy, correction of an anal fistula, a mucosal prolapse, electro-resection, infection or trauma. Anal stenosis leads to increasing constipation, a reduction of stool volume, abdominal cramps and rectal bleeding.
