Summary
Laparoscopy accurately stages peritoneal cancer, assessing feasibility for peritonectomy with hyperthermic chemotherapy. This minimally invasive approach visualizes small tumors missed by imaging, improving patient selection for treatment.
Area of Science:
- Surgical Oncology
- Gastrointestinal Oncology
- Minimally Invasive Surgery
Background:
- The Peritoneal Cancer Index (PCI) aids in evaluating peritoneal surface malignancies for peritonectomy and hyperthermic chemotherapy.
- Radiologic imaging often fails to detect small peritoneal implants, particularly on the small bowel and mesentery, hindering accurate CT-based PCI classification.
Purpose of the Study:
- To evaluate the utility of videolaparoscopy for staging peritoneal carcinomatosis and assessing peritonectomy feasibility.
- To compare laparoscopic PCI assessment with intraoperative findings from open surgery.
Main Methods:
- Videolaparoscopy was used to stage 97 patients with peritoneal carcinomatosis.
- Laparoscopic Peritoneal Cancer Index (PCI) assessment was performed.
- Correlation between laparoscopic PCI and open surgery data was analyzed.
Main Results:
- Full laparoscopic PCI assessment was achieved in 96/97 cases, with accurate staging in most instances (96/96).
- Laparoscopic PCI demonstrated good correlation with open surgery findings.
- No mortality or neoplastic colonization at trocar sites was observed. Patients with extensive small bowel involvement were excluded from peritonectomy.
Conclusions:
- Laparoscopy is a valuable tool for staging peritoneal surface malignancies.
- It enables direct visualization of small cancer nodules, improving the assessment of peritonectomy feasibility.
- Laparoscopic staging enhances patient selection for surgical intervention.
