Abstract:
Objective:To investigate the value of surgical classification and pelvic floor reconstruction in pelvic exenteration for locally recurrent or locally advanced rectal cancer. Methods:A retrospective descriptive study method was used.Perioperative data were collected from 67 consecutive patients with locally advanced or locally recurrent rectal cancer who underwent pelvic exenteration at the Department of Anorectal Surgery,the Second Affiliated Hospital of Navy Military Medical University between November 2021 and November 2022 through the Chinese Combined Pelvic Exenteration Case Database for rectal cancer.The surgical range was divided into two categories:mainly localized in the pelvic cavity(48 cases)and combined with resection of the main tissue of the pelvic wall(1 9 cases).Outcome indexes included:(1)preoperative general data of patients;(2)intraoperative conditions;(3)postoperative recovery and complications(postoperative complications were evaluated by international Clavien-Dindo classification);(4)follow-up(outpatient and telephone follow-up were used to understand the postoperative survival,tumor recurrence and metastasis of patients,and the follow-up time was up to February 28,2023 or the case died).Measurement data are expressed by median(range),and enumeration data are expressed by example(％). Results:In the pelvic resection group,the median age of 48 patients was 57.5 years(range:31-82 years);29 were males and 19 were females;26 of them had locally advanced rectal cancer and 22 had locally recurrent rectal cancer;39 had a history of chemotherapy,immunotherapy or targeted therapy,and 26 had a history of radiotherapy;the median operation time was 425 min(range:240-1 020 min);the median intraoperative blood loss was 500 mL(range:200-4 000 mL);the median time to recovery of intestinal function was 3 d(range:1-9 d);the median recovery time of empty pelvis syndrome was 25.3 d(range:5-105 d);43 patients had postoperative complications＜grade Ⅲ,and of the 5 patients with ≥ grade Ⅲcomplications,2 died of multiple organ failure 7 d after operation,2 patients had surgical hemostasis for massive hemorrhage of pelvic floor wounds after operation,and 1 patient recovered from postoperative respiratory failure after rescue.In the combined pelvic wall resection group,the median age of 1 9 patients was 54.5 years(range:43-76 years);9 were males and 10 were females;4 patients had locally advanced rectal cancer and 15 patients had locally recurrent rectal cancer,all of whom had a history of chemotherapy,immunotherapy or targeted therapy,and 1 5 patients had a history of radiotherapy;the median operation time was 580 min(range:360-960 min);the median intraoperative blood loss was 1 600 mL(range:400-4 000 mL);the median intestinal function recovery time was 3 d(range:2-7 d);the median empty pelvis syndrome recovery time was 62.3 d(range:7-120 d);15 patients had postoperative complications＜grade Ⅲ,and of the 4 patients with grade ≥ Ⅲ,3 patients had surgical hemostatis for postoperative pelvic floor wound bleeding and 1 patient recovered after the second operation for intestinal obstruction.As of February 28,2023 or death,67 patients were followed up for a median of 7.5 months(range:3-1 5 months),and 3 patients died 3-8 months after operation due to rapid tumor progression,severe urinary tract infection,and sudden heart disease during the follow-up period.The remaining 62 cases survived. Conclusion:The surgical classification has guiding significance for preoperative surgical planning in patients with locally advanced or locally recurrent rectal cancer who undergo combined pelvic exenteration,and the method of pelvic floor reconstruction based on biological mesh is safe and feasible in combined pelvic exenteration for locally advanced or locally recurrent rectal cancer.
