Combined transabdominal and transperineal endoscopic pelvic exenteration for colorectal cancer: feasibility and safety of a two-team approach

Abstract

Purpose Pelvic exenteration (PE) is a highly invasive procedure with high morbidity and mortality rates. Promising options to reduce this invasiveness have included laparoscopic and transperineal approaches. The aim of this study was to identify the safety of combined transabdominal and transperineal endoscopic PE for colorectal malignancies. Methods Fourteen patients who underwent combined transabdominal and transperineal PE (T group: 2-team approach, n = 7; O group: 1-team approach, n = 7) for colorectal malignancies between April 2016 and March 2020 in our institutions were included in this study. Clinicopathological features and perioperative outcomes were compared between groups. Results All patients successfully underwent R0 resection. Operation time tended to be shorter in the T group (463 minutes) than in the O group (636 minutes, P = 0.080). Time to specimen removal was significantly shorter (258 minutes vs. 423 minutes, P = 0.006), blood loss was lower (343 mL vs. 867 mL, P = 0.042), and volume of blood transfusion was less (0 mL vs. 560 mL, P = 0.063) in the T group, respectively. Postoperative complications were similar between groups. Conclusion Combined transabdominal and transperineal PE under a synchronous 2-team approach was feasible and safe, with the potential to reduce operation time, blood loss, and surgeon stress.

“…Histopathological analysis revealed complete excision with clear margins. This combination technique may be subject to further developments [1][2][3][4]. We have demonstrated that simultaneous surgery and the sequential procedure can shorten the operating time.…”
