[Aseptic resection of the intraluminal colon in laparoscopy]

Laparoscopic surgery is an "old" technique extending to new applications including colon surgery. Basically, even though surgical technique and indications do not differ from traditional surgery, it has the advantage to eliminate most of the complications associated with an abdominal incision. In order to improve also the outcome of intestinal anastomoses, an aseptic technique by intestinal intussusception previously described (3) has been modified and carried out laparoscopically in 3 pigs and 3 dogs successfully. The animals were sacrificed after 2 months. Anastomoses were evaluated endoscopically by barium enema and by gross and microscopic examination. Results indicated no mortality or complications except for a small area of mucosal peri-anastomotic necrosis in one dog, which spontaneously healed. Therefore, it seems that the aseptic resection of the colon is possible with laparoscopy obtaining at the same time a decreased morbidity related to the abdominal incision and colonic anastomosis.
