[Prevention abdominal contamination by napkin in performance of colonic anastomosis]

A special napkin for performance of colonic anastomosis is proposed. The napkin represents a piece of cellophane with the side cuttings, ending with 2 orifices of 3 cm in diameter. 2 tubes are installed into the piece of cellophane on the upper and lower sides. The mobilized part of the colon and the tumor are put into the napkin. The napkins edges are being fixed to the surgical sheets. The parts of the colon, that are being planned to resect, are isolated from the abdominal cavity and are located in the cellophane bag. After accomplishing the first row of sutures a flowing irrigation of the anastomosed parts of colon is being done. The use of the napkin prevents polluting the abdominal cavity and abdominal wall wound.
