RT Journal Article SR Electronic T1 Extraperitoneal Approach During Peritonectomy in the Right Upper Quadrant for Peritoneal Metastases from Ovarian Malignancies JF In Vivo JO In Vivo FD International Institute of Anticancer Research SP 341 OP 349 DO 10.21873/invivo.12708 VO 36 IS 1 A1 MIKLOS ACS A1 HUBERT LEEBMANN A1 SEBASTIAN HÄUSLER A1 PHILIPP HARTER A1 POMPILIU PISO YR 2022 UL http://iv.iiarjournals.org/content/36/1/341.abstract AB Aim: To present the extraperitoneal approach for the removal of peritoneal metastases in the right upper abdomen in patients with ovarian cancer and to evaluate safety and potential advantages with comparison with the traditional approach. Patients and Methods: Detailed description of the right upper quadrant peritonectomy as extraperitoneal approach. Procedure-specific short-term complications were retrospectively analyzed in a cohort of patients. Results: Sixty-four patients were included. Full-thickness diaphragmatic resection was performed in 17% of primary cases, and in 44% of the patients with recurrent ovarian carcinoma. The rate of complete cytoreduction (CC-0) was 70%. The most common postoperative complication was pleural effusion (32%). Conclusion: The extraperitoneal approach for peritonectomy of the right upper quadrant in patients with ovarian cancer is feasible, with improved access to the right subdiaphragmatic area. This enables a high rate of complete cytoreduction, and simplified and safe surgical dissection in an uncontaminated area under secured vascular structures. The early postoperative outcomes are comparable to those of the traditional transperitoneal approach.
