This new intestinal aspirator is designed to avoid the usual difficulties encountered when decompressing the obstructed colon prior to performing a cecostomy. If partial deflation can be done readily and safely, it often permits easy manipulation of the cecum and facilitates subsequent operative technic. If such drainage is attempted with a trocar, the instrument may become occluded before sufficient decompression is accomplished. When this occurs, removal of the trocar is necessary, with subsequent welling out of intestinal contents. Furthermore, insertion of a large trocar through a tense, thinned out intestinal wall may cause the bowel wall to split, permitting fecal material to ooze around the trocar.
The instrument consists of a large double wall tube so arranged that, when negative pressure is applied, the space between the two walls acts as a suction cup and virtually seals the instrument to the viscus. The suction cup, as well as the large
