Abstract
INTRODUCTION: Recently, use of reduced-port surgery has become widespread; however, it is a difficult operation. Hachisuka et al. developed a method called the umbilical zigzag incision, which enlarges the fascial incision using only an umbilical skin incision. We believe this method will be feasible for concomitant laparoscopic surgery. We report our surgical techniques for concomitant laparoscopic surgery using an umbilical zigzag incision. METHODS: The patient who should receive more than 2 places of abdominal operation were indicated this procedure. In all cases, we made the zigzag incision in the umbilical region. After the linea alba and peritoneum were incised, the wound retractor was inserted through the incision, which enlarges the fascial opening. GelPoint was attached to the wound retractor and the operation was started. RESULTS: We could create a fascial opening of up to 6 cm with the umbilical zigzag incision, which improves the triangulation of forceps and reduces interference among the trocars. The trocars in the center of the abdomen could be utilized for almost all intraperitoneal operations. This procedure was especially useful in cases that included lymph node dissection because dissection of a malignant tumor is a delicate procedure. Furthermore, extraction of specimens and anastomosis went very smoothly because the fascial incision was large enough such that no extension of the incision was needed. No early or late postoperative complications occurred in any case. Postoperative wounds were clear and therefore patient satisfaction levels were high. CONCLUSION: Umbilical zigzag incision may be feasible especially in concomitant laparoscopic surgery.
