[Various techniques for laparoscopic small intestinal anastomosis. A preliminary report].

Three groups with n = 6 pigs were subjected to different techniques of endoscopic small bowel anastomosis. In Group I connection of the gut endings was done, using an all layer stapler-device, otherwise employed as hernia-stapler. Two thirds of the circumference became inverted, one third was everted. Anastomosis of Group II was done with the same stapler device, but all clips were set to evert the wound-endings. Group III consisted of triangularly shaped anastomosis, for which a linear stapler device was being used. All animals survived the investigation period (14 days) and were postmortally examined. Technical aspects and clinical results are being discussed.
