Using an indwelled test tube as a good "navigator" during enterostomy closure.

Surgeons often have difficulty in identifying a suitable incision line to enter the peritoneal cavity for stoma mobilization during enterostomy closure. A mini-size test tube that is preoperatively placed into the stoma can act as an efficient guide in finding a free area to enter the peritoneal cavity, by supplying efficient counter traction and a palpable marker of the intestinal wall.
