Abstract
Occasionally,we find the patient whose stoma is hard to be cared by oneself at the sitting position because of the hanging upper abdominal wall over the stoma,though the stoma was made at the preoperatively marking site. It has frequently occurred in obese patients or old women with redundant abdominal wall. The lower abdominal wall of the obese patienth angsd own,projectsa tth e sitting position,and the increasing thickness of subcutaneous fatty tissue is also observed. But the colon situated in the abdominal wall as the stoma and the surrounding tissue do not stretch,and the stoma is depressed relatively and covered by the upper abdominal fatty wall.
In order to prevent this trouble,we prepare the enough length of the colon for the subcutanous part of the colostomy,and we think that the site of the colostomy should be made at the higher level than usual,namely at the level of the navel or slightly at lower level than it.
