Left-side hepatectomy in living donors: Through a reduced upper-midline incision for liver transplantation

Background We present our attempts at reducing the length of incision in living donor left-side hepatectomy without laparoscopic approach. Methods The chief surgeon initially made a 10-cm upper midline incision and performed all procedures through a minilaparotomy without abdominal wall lifting or pneumoperitoneum. For the procedures in the lateral and deep areas, we effectively applied traction to the wound in multiple directions using a wound retraction system so that the chief surgeon could obtain a good direct view. We also placed a fiberscope on the minilaparotomy so that the assistant surgeons could obtain an additional video view via a monitor. Surgeons lengthened the incision at their own discretion if the initial length was thought to be too short for the donor's safety. Since February 2009, we have employed this operation for 19 living donors (12 lateral segmentectomies and 7 left hepatectomies) and compared parameters between the 19 donors and 34 previous donors who underwent the procedure with standard incision (11 lateral segmentectomies and 23 left hepatectomies). Results The resultant length of incision was significantly reduced in operations with reduced incision length as compared with standard incision. Clinical outcomes such as operation time and length of hospital stay were comparable or significantly reduced with the reduced incision. The resultant incision length remained within 10 and 12 cm in lateral segmentectomy and left hepatectomy cases, respectively, whose body mass index was less than 22. Conclusion It appears to be feasible to reduce the incision length for living donor left-side hepatectomy, especially in nonobese cases.
