Staging videolaparoscopy and peritoneal citology in the colorectal carcinomas for the preoperative section of the HIPEC treatment

The authors report their preliminary results about preoperative videolaparoscopy staging of colorectal cancer cases. The examination for peritoneal cytology, performed during preoperative staging could thus be used to plan since the first surgical operation in case of positive cytology (even more in presence of evident carcinosis which was not revealed through CT), the combination with Intraperitoneal Chemo-Hyperthermia (HIPEC). Realizing this procedural hypothesis requires a preoperative performance of a staging videolaparoscopy, in order to explore the peritoneal surface, exclude the macroscopic presence of carcinosis (in this case it is indicated to perform peritonectomy and HIPEC) and detect the cytologic study (through washing or aspiration of potential ascitic effusion). The expected results aim to see a significant reduction of the peritoneal recurrence, but till now our proposal is a medical hypothesis: in fact results should be considered temporarily because the reduced observation time.
