Objective: This study of living liver transplant donors compared postoperative atrophy of the rectus abdominis after an upper abdominal midline incision vs a Mercedes incision. Methods: A total of 110 donors underwent left-side donor hepatectomy in our hospital from 2007 to 2016. We analyzed the postoperative computed tomography data of 102 cases 3, 6, and 12 months after surgery. Donors were categorized as having a midline incision (MID group, n = 39)or a Mercedes incision (MER group, n = 63). The rectus abdominis was assessed on computed tomography images, and the percentage of muscle thickness (PMT)was compared in the 2 groups. Results: Patient age, sex, and body mass index did not differ in the 2 groups. Laparoscope-assisted hepatectomy was only performed in the MID group, while open hepatectomy was performed mainly in the MER group. The mean PMT of the rectus abdominis did not change 3, 6, and 12 months after surgery in the MID group but decreased to 80%, 76%, and 72% of the baseline value in the MER group 3, 6, and 12 months after surgery, respectively. The PMT values were significantly lower in the MER group than in the MID group at all 3 time points (P <.001). In the MER group, rectus abdominis atrophy was significantly worse on the right side than on the left. There was no significant difference in morbidity between the 2 groups. Conclusion: In living donor liver transplant, the Mercedes incision resulted in significantly greater atrophy of the rectus abdominis in donors compared with the midline incision.
