In order to reduce the risk of visceral injury for patients with upper abdominal adhesions, we devised an alternative to the umbilical approach. Five patients who had undergone a previous upper abdominal laparotomy and were scheduled for gynecologic laparoscopic surgeries at our hospital were evaluated. A micro-trocar was inserted via the posterior vaginal fornix and the periumbilicus was observed using a micro-laparoscope inserted in the micro-trocar. A trocar for conventional laparoscopy was inserted into the umbilicus under micro-laparoscopic observation in the cul-de-sac to avoid visceral organ adherent to the periumbilicus. Four cases had adhesions of the transverse colon, small bowel or omentum to the upper abdomen due to previous surgery; however, we were able to accomplish laparoscopic surgery without injury to adhesive organs in all patients. The micro-laparoscopic primary approach via the posterior vaginal fornix is a safe primary approach for patients who have undergone a previous upper abdominal laparotomy.
