Expert Surgical Excision of Peritoneal Malignancies
A peritonectomy is a highly complex surgical procedure designed to strip away the peritoneum, which is the membrane that lines the inner wall of the abdomen and covers the internal organs. When cancer spreads to this lining, it creates a condition known as peritoneal carcinomatosis.
Standard surgical techniques are generally insufficient to clear thousands of tiny tumor nodules from the abdominal cavity. To achieve a true curative intent, surgical oncologists utilize an Advanced Peritonectomy Procedure. This standardized approach allows for the systematic removal of all visible tumor deposits.
Dr. Snita Sinukumar possesses the specialized high volume training required to perform these extensive resections safely, ensuring maximum tumor clearance while preserving the maximum possible organ function.
Standardized Peritonectomy Procedures
Depending on the Peritoneal Cancer Index (PCI) calculated during staging, one or a combination of the six standard peritonectomy procedures is performed to achieve complete cytoreduction:
- Anterior Parietal Peritonectomy: Stripping the lining from the front abdominal wall.
- Right Upper Quadrant Peritonectomy: Removing the tumor from the right diaphragm and liver capsule, often involving right hemicolectomy.
- Left Upper Quadrant Peritonectomy: Stripping the left diaphragm, which may require splenectomy and distal pancreatectomy.
- Pelvic Peritonectomy: Excision of the pelvic lining, including total hysterectomy and bilateral salpingo oophorectomy in female patients.
- Omentectomy: Complete removal of the greater and lesser omentum where tumor cells frequently aggregate.
- Bowel Resection and Anastomosis: Removing heavily involved segments of the small or large intestine and carefully reconnecting the healthy tissues.
Completeness of Cytoreduction (CC) Score
The primary goal of a peritonectomy is to achieve a Completeness of Cytoreduction score of CC-0 or CC-1. This is the most critical prognostic factor for patient survival.
A CC-0 score means no visible tumor remains. A CC-1 score means the remaining tumor nodules are smaller than 2.5 millimeters. Meticulous surgical effort is focused to ensure the patient reaches these exact margins, as any larger residual tumors will fail to respond to subsequent therapies.
Integration with HIPEC
A peritonectomy is almost always followed immediately by Hyperthermic Intraperitoneal Chemotherapy (HIPEC) in the same operating theater.
Once the advanced peritonectomy has reduced the tumor burden to microscopic levels, heated chemotherapy is circulated directly into the abdomen. Because the thick peritoneal lining has been removed, the chemotherapy drugs can penetrate the raw tissue surfaces deeply and eradicate any remaining microscopic cancer cells.
