ABSTRACT
PURPOSE:
This study compared the perioperative and pathologic outcomes between an extralevator abdominoperineal resection (APR) in the prone position and a conventional APR.METHODS:
Between September 2011 and March 2014, an extralevator APR in the prone position was performed on 13 patients with rectal cancer and a conventional APR on 26 such patients. Patients' demographics and perioperative and pathologic outcomes were obtained from the colorectal cancer database and electronic medical charts.RESULTS:
Age and preoperative carcinoembryonic antigen (CEA) level were significantly different between the conventional and the extralevator APR in the prone position (median age, 65 years vs. 55 years [P = 0.001]; median preoperative CEA level, 4.94 ng/mL vs. 1.81 ng/mL [P = 0.011]). For perioperative outcomes, 1 (3.8%) intraoperative bowel perforation occurred in the conventional APR group and 2 (15.3%) in the extralevator APR group. In the conventional and extralevator APR groups, 12 (46.2%) and 6 patients (46.2%) had postoperative complications, and 8 (66.7%) and 2 patients (33.4%) had major complications (Clavien-Dindo III/IV), respectively. The circumferential resection margin involvement rate was higher in the extralevator APR group compared with the conventional APR group (3 of 13 [23.1%] vs. 3 of 26 [11.5%]).CONCLUSION:
The extralevator APR in the prone position for patients with advanced low rectal cancer has no advantages in perioperative and pathologic outcomes over a conventional APR for such patients. However, through early experience with a new surgical technique, we identified various reasons for the lack of favorable outcomes and expect sufficient experience to produce better peri- or postoperative outcomes.
