Abstract:
Objective:To evaluate the efficacy of vacuum sealing drainage (VSD) in the comprehensive management of full-thickness perineal wound dehiscence following pelvic exenteration (PE).Methods:This study employed a descriptive case series design. We retrospectively analyzed the clinical data of 29 patients who developed postoperative perineal wound infections with full-thickness dehiscence after PE. These cases included 16 patients from the Department of General Surgery at Jiangyin People's Hospital (Jiangsu Province) and 13 patients from the Department of Colorectal Surgery at the Second Affiliated Hospital of Naval Medical University (Shanghai Changzheng Hospital). VSD was applied to manage the dehisced wounds, with outcomes assessed based on wound healing time, complications, and follow-up data.Results:A total of 29 patients were included in the study. The operative time for PE was (498 ± 83) minutes. Among them, 23 patients underwent combined sacrococcygeal resection. The median number of VSD devices used was 28 (22, 39). The postoperative perineal wound healing time was 95 (82, 110) days in patients who underwent combined sacrococcygeal resection, 74 (63, 89) days in those without sacrococcygeal resection, 93 (79, 102) days in those treated with simple pelvic-abdominal isolation using a biological basement membrane mesh and 76 (60, 91) days in those who received combined pelvic packing with a pedicled omental flap. All patients uniformly developed Clavien-Dindo grade III complications at 2 weeks postoperatively, manifesting as perineal wound infection and dehiscence, which were successfully managed with VSD therapy. Subsequent evaluation identified delayed (>30 days) grade III complications, including enterocutaneous (3 cases) and urinary (2 cases) fistulae, all requiring surgical revision. All patients completed the follow-up at 6 months postoperatively. Three patients still presented with minimal exudate from the perineal wound, which resolved after standardized wound care and packing with alginate silver ion dressings. Four cases (13.8%) developed stoma high-output syndrome, which improved after oral medication. Eight patients (27.6%) developed adhesive intestinal obstruction, which improved with conservative treatment.Conclusions:VSD demonstrates unique advantages in managing complex wounds. For full-thickness perineal wound dehiscence after PE, VSD is a safe and effective therapeutic strategy.
