Official Description

Intraoperative hyperthermic intraperitoneal chemotherapy (HIPEC) procedure, including separate incision(s) and closure, when performed; first 60 minutes (List separately in addition to code for primary procedure)

Common Language Description

Intraoperative hyperthermic intraperitoneal chemotherapy (HIPEC) is a specialized procedure that involves the administration of heated chemotherapy directly into the peritoneal cavity during surgery. This technique is primarily utilized after the surgical excision of malignant tumors located in the abdominal region. The objective of HIPEC is to eliminate any residual cancer cells that may remain after the tumor has been removed, thereby reducing the risk of recurrence. The chemotherapy agents used in this procedure are heated to temperatures between 41-43 degrees Celsius (106-109 degrees Fahrenheit), which enhances their effectiveness by allowing deeper penetration into the cancerous tissues. The procedure is characterized by the use of separate incisions for the insertion of catheters that facilitate the delivery and circulation of the heated chemotherapy solution throughout the abdominal cavity. This localized treatment approach minimizes systemic exposure to the chemotherapy drugs, thereby reducing potential side effects associated with traditional chemotherapy methods. The entire process typically lasts for about 60 minutes, during which the heated solution is circulated, and upon completion, it is drained from the abdomen, followed by rinsing with saline and closure of the incisions.

1. Indications

The intraoperative hyperthermic intraperitoneal chemotherapy (HIPEC) procedure is indicated for patients who have undergone surgical resection of abdominal tumors, particularly in cases where there is a high risk of residual cancer cells remaining in the peritoneal cavity. The following conditions may warrant the use of HIPEC:

  • Malignant Peritoneal Mesothelioma - A rare cancer that affects the lining of the abdominal cavity, often requiring aggressive treatment.
  • Ovarian Cancer - Advanced stages of ovarian cancer where traditional treatments may not be sufficient to eliminate all cancerous cells.
  • Colorectal Cancer with Peritoneal Carcinomatosis - When colorectal cancer spreads to the peritoneum, HIPEC can be used to target these areas directly.
  • Gastric Cancer - In cases of advanced gastric cancer, HIPEC may be employed to address remaining cancer cells post-surgery.

2. Procedure

The intraoperative hyperthermic intraperitoneal chemotherapy (HIPEC) procedure involves several critical steps to ensure effective delivery of the chemotherapy agents. The following outlines the procedural steps:

  • Step 1: Surgical Preparation - The patient is prepared for surgery, and the surgical team ensures that all necessary equipment and chemotherapy agents are ready for use. Anesthesia is administered, and the primary surgical procedure to remove the tumor is performed first.
  • Step 2: Catheter Placement - After the tumor has been excised, separate incisions may be made to insert inlet and outlet catheters into the abdominal cavity. These catheters are essential for the delivery and drainage of the heated chemotherapy solution.
  • Step 3: Heating the Chemotherapy Solution - The chemotherapy agents are mixed with a carrier solution and heated to a temperature range of 41-43 degrees Celsius (106-109 degrees Fahrenheit) using a perfusion machine. This heating process is crucial for enhancing the drug's efficacy.
  • Step 4: Infusion of Chemotherapy - The heated chemotherapy solution is pumped into the peritoneal cavity through the inlet catheter. The solution is circulated throughout the abdominal cavity for a duration of 60 minutes, allowing for maximum exposure of the cancer cells to the chemotherapy agents.
  • Step 5: Drainage and Rinsing - Once the infusion time is complete, the chemotherapy solution is drained from the abdomen through the outlet catheter. The abdominal cavity is then rinsed with a saline solution to remove any residual chemotherapy agents.
  • Step 6: Closure of Incisions - After rinsing, the surgical team removes the catheters and closes the incisions made for the procedure, ensuring proper healing and recovery.

3. Post-Procedure

Following the intraoperative hyperthermic intraperitoneal chemotherapy (HIPEC) procedure, patients are typically monitored in a recovery area for any immediate post-operative complications. Expected recovery may vary based on individual patient factors and the extent of the initial surgery. Patients may experience some discomfort or pain at the incision sites, which can be managed with appropriate pain relief medications. It is essential for healthcare providers to monitor for signs of infection or other complications during the recovery period. Follow-up appointments will be necessary to assess the patient's overall recovery and to determine the effectiveness of the HIPEC treatment in conjunction with the primary surgical intervention.
