[Disorders of wound healing of the sacral cavity after abdomino-perineal resection of the rectum].

In 95 patients it was necessary to perform abdominoperineal resection and colostomy due to malignant tumours of the rectum, the anus, as well as gynaecological tumours. After standardized preoperative preparation and comparable operative techniques in more than 93 per cent of the cases we performed suction drainage of the sacral cavity. In 86 per cent we observed primary perineal wound closure and the patients were spared lengthy secondary wound healing.
