Objective Total parietal peritonectomy is gradually being recognized as a surgical option for advanced ovarian cancer; however, evidence regarding its efficacy and safety remains insufficient. Herein, we aimed to assess the short- and long-term post-operative safety profiles of total parietal peritonectomy.
Methods We reviewed the medical records of post-operative morbidity and mortality of patients who underwent cytoreductive surgery with total parietal peritonectomy for stage III and IV ovarian cancer between April 2018 and January 2023.
Results Fifty patients were enrolled in the study: 31 who underwent primary cytoreductive surgery and 19 who underwent interval cytoreductive surgery. The median age of all patients was 57 (range, 23–74) years. The median follow-up period was 22 (range, 3–59) months. Of 44 patients (88%) with stage IIIC/IV, 38 patients (76%) had high-grade serous carcinoma. The complete resection rates were 94%, 91%, and 100% in all patients, the primary cytoreductive surgery group, and the interval cytoreductive surgery group, respectively. There were 63 post-operative complication events overall, including 17 (27%) major complication events in 15 patients within 1 year post-operatively. Ten major complications occurred within 30 days of surgery, mainly in the primary cytoreductive surgery group (9 cases). Regarding complication type, the most frequent major event was pleural effusion (3 cases, 7%). After 30 days, there were a total of 17 all-grade complication events, of which ileus and hydronephrosis were major complications in 3 cases each (18%). There were no mortalities related to cytoreductive surgery. The scheduled adjuvant chemotherapy could be completed in 96% of patients.
Conclusions Total parietal peritonectomy is a feasible procedure for managing advanced ovarian cancer. Short- and long-term complications may include pleural effusion and ileus/hydronephrosis, respectively.
