Objective: Complete surgical cytoreduction is the most important prognostic factor of survival in patients with peritoneal metastases from various cancers, including ovarian cancer. In order to achieve the optimum result, surgeons use extensive procedures that involve peritonectomies and multivisceral resections. Cytoreductive surgery (CRS) aims to eliminate all macroscopic disease by achieving complete cytoreduction. This article describes a surgical approach designed to achieve total extraperitoneal access for parietal peritonectomy.
Study design: Visceral resections and parietal peritonectomy procedures must be conducted for complete removal of all visible malignancy. This article presents a technique that combines existing surgical approaches (anterolateral parietal peritonectomy, complete pelvic peritonectomy with sleeve resection of the sigmoid colon, and right and left upper quadrant peritonectomies) to achieve access to the upper abdomen, the lateral abdomen and the pelvis while keeping the peritoneum intact.
Results and conclusion: This approach facilitates the peritonectomies necessary for complete cytoreduction, and improves access to difficult sites such as the pelvis and the subdiaphragmatic areas in a standardized manner that can be reproduced safely by an experienced surgical team.

INDICATIONS FOR USE & INTENDED USE DISCLOSURES
- The Renuvion Precise, Precise Open, and J-Plasma Handpieces are intended to be used with compatible electrosurgical generators for the delivery of radiofrequency energy and/or helium plasma for cutting, coagulation, and ablation of soft tissue during open surgical procedures.
- Apyx Medical wants to present to you with current scientific discourse.
- Risk associated with the use of the device may include: Helium embolism into the surgical site due to inadvertent introduction into the venous or arterial blood supply system, unintended burns (deep or superficial), pneumothorax, temporary or permanent nerve injury, ischemia, fibrosis, infection, pain, discomfort, gas buildup resulting in temporary and transient crepitus or pain, bleeding, hematoma, seroma, subcutaneous induration, pigmentation changes, increased healing time, and/or unsatisfactory scarring. There may be additional risks associated with the use of other devices along with Renuvion/J-Plasma and there may be an increased risk for patients who have undergone prior surgical or aesthetic procedures in the treatment area.
As with any procedure, individual results may vary. As with all energy devices there are inherent risks associated with its use, refer to the IFU for further information.
