Abstract
Purpose
We devised a new method for the safe introduction of the first trocar and induction of pneumoperitoneum for laparoscopic excision of the large intestine.
Methods
With this method, a small laparotomy is first conducted according to the size of the exposed affected intestinal tract or tumor size, prior to the application of a LAP DISC (LD) to the wound and introduction of a 12-mm trocar for the establishment of pneumoperitoneum. The method is advantageous in that organ injury and vessel injury are avoided when the small laparotomy is conducted first, and prompt transition to a conventional laparotomy is possible. The diaphragm of the iris bulb can be controlled in a non-stepwise manner. In addition, trocars, the stapler, and other instruments, can be inserted under the pneumoperitoneum. Furthermore, the use of a 5-mm flexible scope allows surgical maneuvers, except for application of LD, to be conducted via 5-mm trocars. In addition, the 5-mm scope can be inserted through any trocar, allowing multidirectional avoidance of dead space and intraperitoneal observation. When only 5-mm trocars are used, it is not necessary for the sites of trocar puncture to be closed by sutures, and this minimizes the risk of adhesions and port-site herniation. The method is also considered to be excellent from the point of view of esthetics.
Results
We employed this surgical approach in 50 patients with colorectal cancer at our hospital. None of the patients developed any traumatic complications associated with the insertion of trocars, and none of the patients, even those with a past history of abdominal operation, required conversion to conventional laparotomy.
Conclusions
Based on these results, this method involving a small laparotomy prior to the application of an LD and introduction of a 12-mm trocar for establishing pneumoperitoneum, with the efficient use of a 5-mm flexible camera, is considered to be safe and useful for laparoscopic excision of the large intestine.
