During staging laparoscopy, peritoneal washings are obtained to provide what type of information?

• A. Infectious disease status
• B. Immediate therapeutic effect
• C. Prognostic information to guide therapy
• D. Diagnostic histology of liver

Answer: (C)

The main concept is that peritoneal washings during staging laparoscopy provide prognostic information through cytology to guide treatment decisions. Collecting washings allows detection of malignant cells in the peritoneal cavity, which reflects microscopic spread and helps shape the overall plan—such as the choice of systemic therapy, the aggressiveness of planned debulking, or other treatment strategies. This information is about prognosis and guiding therapy, not about acute infection status, not a therapeutic intervention itself, and not a histologic study of the liver.
