HIPEC Surgery Procedure: Step-by-Step Process & Timeline

Step 1: Pre-Surgery Preparation

Before HIPEC is planned, the patient undergoes a detailed medical evaluation. This typically includes blood tests, imaging such as CT scans and sometimes MRI, anaesthesia fitness review, and surgical oncology consultation. The current HIPEC page on the site also notes the importance of disease mapping and patient selection, including advanced imaging and staging methods when needed.

Patients are then prepared for surgery with standard preoperative instructions such as fasting, medication review, hospital admission planning, and consent. Since HIPEC is performed as part of a major abdominal cancer operation, general anaesthesia is used so that the patient remains unconscious and pain-free throughout the procedure.

Step 2: Cytoreductive Surgery (Tumour Removal)

The first major surgical stage is cytoreductive surgery. This means removing all visible tumour deposits from the abdominal cavity as completely as possible. The Cancer Surgery Clinic HIPEC page clearly identifies cytoreductive surgery as a central part of treatment and highlights Dr. Ganesh Nagarajan’s expertise in complex abdominal cancer surgery, multiorgan resections, and complete removal of visible peritoneal disease where feasible.

Depending on the disease extent, the surgeon may need to remove tumour deposits from the peritoneal surfaces, bowel, omentum, or other involved structures while preserving uninvolved healthy organs whenever possible. In most HIPEC cases, this is performed through an open abdominal approach because it allows full disease assessment and tumour clearance, although minimally invasive techniques are part of the broader surgical expertise highlighted on the site for selected cancer operations.

Step 3: HIPEC Infusion

After visible tumour removal is completed, the HIPEC phase begins. Heated chemotherapy drugs are prepared and circulated directly inside the abdominal cavity. Your content brief mentions examples such as mitomycin C and cisplatin; the exact drug used depends on the tumour type, surgical plan, and institutional protocol. The chemotherapy is typically heated to around 41–42°C and circulated for approximately 60 to 90 minutes to expose residual microscopic cancer cells to high local concentrations of treatment. This timing-and-temperature concept matches the standard HIPEC process you want explained and is consistent with how the site frames HIPEC as heated chemotherapy delivered after surgical clearance.

Catheters and a specialized perfusion setup are used to circulate the solution throughout the abdominal cavity in a controlled way. This helps achieve uniform exposure to the heated chemotherapy while the surgical and anaesthesia teams closely monitor the patient throughout the process. The site’s focus on multidisciplinary expertise and technically demanding abdominal surgery supports explaining this as a carefully coordinated intraoperative step rather than a simple infusion.

Step 4: Post-Chemotherapy Draining

Once the chemotherapy has circulated for the planned duration, the solution is drained from the abdominal cavity. The abdomen is then reassessed, and the team prepares for the final surgical stage. This drainage step is important because it marks the completion of the heated intraperitoneal chemotherapy component of the HIPEC surgery process.

Step 5: Closing the Surgical Site

After the HIPEC infusion is completed and drained, the surgeon closes the surgical site. If reconstruction or bowel rejoining is required, that may be done depending on the procedure performed. Sterile dressings are applied, and the patient is shifted to recovery or critical care for close monitoring after this major operation. Postoperative care is an important part of the treatment pathway described by the clinic, especially because HIPEC is performed only in selected cases requiring specialized perioperative support.

The total operation can be long because HIPEC includes both major tumour-removal surgery and a chemotherapy perfusion phase. A practical patient-facing explanation is that surgery commonly takes 6 to 12 hours, depending on how extensive the disease is, which organs are involved, and how much tumour needs to be removed. The site itself strongly supports this framing by presenting HIPEC as a technically demanding, highly specialized abdominal cancer procedure rather than a routine operation.

HIPEC also requires a multidisciplinary team. At minimum, that includes the surgical oncologist, anaesthesiologists, operating room nurses, critical care support, and postoperative recovery staff. Cancer Surgery Clinic positions Dr. Ganesh Nagarajan as a specialist in technically demanding abdominal and GI cancer surgery, and the broader site highlights advanced surgical care delivered through expert teamwork.

Key equipment used during the procedure includes surgical instruments for tumour removal, abdominal catheters for perfusion, and a specialized heating-circulation system that maintains the chemotherapy solution at a controlled temperature throughout the HIPEC phase. For selected cancer operations, the site also highlights laparoscopic and robotic expertise, which supports describing the clinic as equipped for advanced cancer surgery workflows.

Before HIPEC Surgery

Before HIPEC, the patient typically goes through diagnosis confirmation, imaging review, blood investigations, fitness evaluation, and surgical planning. The clinic’s HIPEC page also highlights evaluation of disease burden and suitability for cytoreductive surgery, including staging methods and detailed patient selection.

During the HIPEC Procedure

During the operation, the timeline usually follows this order: anaesthesia, abdominal exploration, cytoreductive surgery, heated chemotherapy infusion, chemotherapy drainage, and closure. This is the clearest way to explain HIPEC surgery step by step for patients searching for what happens during HIPEC surgery.

After Surgery: Post-Surgery Care and Recovery

After the operation, the patient is monitored in recovery and sometimes in intensive care or a high-dependency setting, especially in the first 24 to 48 hours. A practical hospital-stay estimate for a patient information page is 7 to 14 days, depending on the extent of surgery, bowel recovery, pain control, nutrition, and any complications. The clinic site emphasizes that postoperative care and multidisciplinary monitoring are part of proper HIPEC treatment.

Pain is managed with IV medicines, epidural or opioid-based strategies when appropriate, and a structured postoperative recovery plan. Patients may also need IV fluids, nutritional support, drains, wound care, and gradual mobilization. This matches the site’s overall positioning of advanced surgical care and recovery support for complex GI and abdominal cancer surgery.

A useful patient-facing follow-up schedule to mention is review after about 1 week, 1 month, 3 months, and then at regular intervals based on the cancer type and oncology plan. This should be framed as a typical pattern that may vary from patient to patient. The website consistently presents treatment planning as individualized under specialist care.

Because HIPEC is a major operation, there are important surgical risks to discuss clearly. The clinic’s HIPEC page specifically mentions risks such as infection, bleeding, bowel complications, and prolonged recovery. These should absolutely be included because they are already consistent with the website’s own treatment framing.

You can also responsibly expand this section to include possible damage to nearby organs, anaesthesia-related risks, and blood clots, especially in a procedure page focused on what to expect. Post-surgery complications may include nausea, vomiting, bowel dysfunction, wound issues, temporary nutritional challenges, and in some cases kidney or liver stress depending on the chemotherapy used and the extent of surgery. These added details are reasonable extensions of the site’s major-surgery framing, but the strongest on-site support remains infection, bleeding, bowel complications, and prolonged recovery.

Complications are managed through close monitoring by the surgical, anaesthesia, nursing, and recovery teams. Early mobilization, fluid balance, pain control, drain care, wound monitoring, and blood test review are all part of postoperative management in high-complexity abdominal cancer surgery. Cancer Surgery Clinic consistently positions these cases as specialist-managed procedures requiring expertise across the full treatment pathway.

In the first 24 to 48 hours, the focus is usually on close monitoring, pain relief, fluid balance, breathing exercises, and assessing bowel recovery. Some patients require ICU or high-dependency care during this phase, especially after long or extensive procedures. The site’s framing of HIPEC as complex abdominal surgery supports setting expectations for intensive early monitoring.

Over the next several days, the goals are to help the patient start moving, gradually restart oral intake when safe, manage drains and wounds, and support recovery of strength. Many patients take 2 to 3 weeks to regain basic mobility and light daily functioning, while full recovery can take several months, especially if multiorgan surgery was needed. This is consistent with the site’s warning that recovery can be prolonged after HIPEC.

Patients should be told that recovery timelines vary widely depending on tumour burden, the extent of cytoreductive surgery, nutritional status, medical fitness, and whether additional cancer treatment is needed afterward. That individualized approach is closely aligned with how Dr. Ganesh Nagarajan’s site presents decision-making and surgical planning.
