The length of the rectum, together with the Perineal region (anal canal), is 15 to 16 cm. The length of the anal canal is 2.5—3 cm, that of the rectal ampula 9 cm, and of the rectosigmoid region 3 cm (Fig. 3).
In the pelvis the rectum has bends both in the sagittal (Figs 1 and [...]

BRIEF SURGICAL ANATOMY OF THE COLON
The mucous and submucous membranes of the rectum and anal canal are provided with a dense network of lymphatics which extensively anastomose with each other. From the anus and the perineal rectum, lymph passes to the inguinal and, partly, to the femoral nodes, and goes upwards through the inguinal fold (Fig. 13). The lymphatic pathways, [...]

Incomplete internal fistulas, that is, those with a single internal opening into the rectal lumen are met wth only in [...]
In female patients with an anterior high-level fistula it is not allowed to divide the sphincter through the anterior vaginal wall because of the danger of incontinence of wind and faeces. Therefore we have developed a new operation for these patients. Under local or mixed inhalation anesthesia, the fistulous tract on the perineum is excised [...]

DIVISION OF SPHINCTER FOR THERAPEUTIC PURPOSES»In some diseases of the rectum we have to resort to partial division of the anal sphincter in the course of operation, so that its function could be temporarily arrested or decreased.
It is our practice to perform such sphincterotomy in operations for anorectal abscesses, anal fistulas and anal fissures by incising the sphincter from the [...]
