[Improvement of perineal wound healing following rectum amputation by omentum flap]

The aim of the presented study was to find whether significant improvement in perineal woundhealing could be achieved by placing pedunculate parts of greater omentum in the sacral cavity after rectal amputation. 70 patients undergoing rectal amputation were evaluated, in 34 patients pedunculate parts of the greater omentum were positioned in the presacral cavity. Results show that an omentum flap improves primary perineal woundhealing and reduces per secundam woundhealing time (p less than 0.025). Since regular placement of pedunculate parts all wounds were closed after 3 months. Sinus formation is reduced (p less than 0.05). Suction drainage must be removed early, otherwise infections aggravate woundhealing going up the tube (p less than 0.001). We conclude from our results that the placement of pedunculate parts of the greater omentum in the sacral cavity after rectal amputation is a useful method to improve perineal woundhealing and should be done as routine procedure.
