An experimental technique of laparoscopic bowel resection and reanastomosis.
With the development of laparoscopic cholecystectomy, surgeons have been stimulated to develop techniques that allow many open surgical procedures to be performed laparoscopically. Appendectomy, hernia repair, and vagotomy have already been introduced clinically. Laparoscopic bowel resection, however, is somewhat more complicated. Bowel transection, mass tissue removal, and reanastomosis in the proper geometric fashion are critical to the success of this type of operation. The introduction of the Endo-GIA stapler (United States Surgical Corp., Norwalk, CT) will make this procedure feasible on a large-scale basis. The major problem with bowel resection is not transection or tissue removal, but, rather, reanastomosis. With intracorporeal anastomosis, manipulation of the bowel with proper orientation becomes difficult. This is less of a problem when performing low-anterior resection, however, because one of the bowel limbs is fixed. The purpose of this study was to develop a technique in the laboratory that would ensure proper orientation of the two bowel limbs, with minimal manipulation prior to performance of the anastomosis. The technique that we developed and describe herein does not require manual orientation during anastomosis. Improper bowel alignment with kinking and twisting is thereby avoided. The technique appears to be useful for small- and large-bowel resections, but not for low-anterior resection. For this technique to become a reality clinically, longer endoscopic staplers with taller staple height will be required.
