Experimental development in colorectal surgery.
A one year research programme on endoscopic colorectal resections was carried out at the University of Tübingen. Two research lines were planned: the development of the required technologies and the development of the surgical procedure. During the research programme on technologies a new device provided with an air proof system for transanal insertion of the anvil of a divisible stapler and a new technique for closure of the colonic and rectal stumps (cable binding technique) were developed. Such technological innovations enabled the authors to accomplish a new combined laparoscopic-rectoscopic procedure which was performed according to four different variants in a series of 32 animals. The last 15 consecutive successful cases, performed according to the definitive procedure, represented a standardized animal trial before starting the clinical investigation.
