 Pressurized intraperitoneal aerosol chemotherapy is a procedure involving the administration of intraperitoneal chemotherapy in aerosolized form through laparoscopy. It enables superior distribution and depth of penetration of chemotherapy. Pre procedure, you are asked to undergo blood tests and body scans. The doctor may advise you to stop certain medications a few days before the procedure. On the day of the procedure, you are administered general anesthesia after which the surgeon inserts tubes via small incisions into the peritoneal cavity. First, small tissue samples of the tumor are retrieved. Then chemotherapy in the form of aerosol under pressure is sprayed inside the abdominal cavity with a special instrument capped open for 10 minutes and left for 13 minutes. At the end of the procedure, the pressure is released and the gas aspirated and the skin incisions are closed. The entire procedure takes about 90 minutes. Post procedure, you may be asked to stay in the hospital for 1-2 days depending on your recovery.
