What to Expect During HIPEC Surgery for Abdominal Cancers

HIPEC surgery – short for hyperthermic intraperitoneal chemotherapy – is a specialised, two-part cancer treatment that combines aggressive surgical tumour removal with a targeted dose of heated chemotherapy delivered directly into the abdominal cavity. Designed for cancers that have spread to the peritoneum, the HIPEC procedure offers patients with otherwise difficult-to-treat abdominal malignancies a meaningful chance at extended survival. This article walks you through everything you need to know – from candidacy criteria and procedure steps to recovery timelines, potential side effects, and real-world outcomes, as performed by the specialist team at SPARSH Hospitals – Global Care.

HIPEC Surgery: The Basics

Cancer that spreads to the peritoneal cavity, the thin membrane lining your abdomen and covering most abdominal organs, presents one of the most challenging treatment scenarios in oncology. Standard intravenous chemotherapy struggles to reach cancer cells embedded in the peritoneum at therapeutic concentrations. Hyperthermic intraperitoneal chemotherapy was developed specifically to overcome this limitation.

The HIPEC procedure involves two sequential phases performed in a single operating session. First, the surgical oncologist performs cytoreductive surgery (CRS), a meticulous operation aimed at removing every visible tumour nodule from the abdominal cavity. Once the surgical team achieves maximal cytoreduction, heated chemotherapy drugs (typically between 41°C and 43°C) are pumped directly into the peritoneal cavity and circulated for 60 to 90 minutes. This “hot chemotherapy” bath targets any remaining microscopic cancer cells with precision, delivering drug concentrations far higher than systemic chemotherapy could safely achieve without exposing the rest of the body to the same dose.

At SPARSH Hospitals – Global Care, our surgical oncology team offers comprehensive HIPEC surgery treatment details and end-to-end peritoneal cancer surgery support to help patients make informed, confident decisions about their care pathway.

What Is HIPEC Surgery and Who Is a Candidate?

Not every patient with peritoneal cancer is a suitable candidate for HIPEC surgery. The procedure demands a high level of physiological fitness and a disease profile that makes complete or near-complete cytoreduction feasible. Your multidisciplinary team at SPARSH Hospitals – Global Care evaluates each patient against a detailed set of clinical criteria before recommending the procedure.

Cancers Commonly Treated with HIPEC

• Appendiceal cancer (including pseudomyxoma peritonei) – HIPEC produces some of its strongest survival results here
• Colorectal cancer with peritoneal metastasis
• Ovarian cancer – both primary and recurrent disease
• Gastric cancer with peritoneal spread
• Peritoneal mesothelioma
• Small bowel cancer and selected sarcomas involving the peritoneum

Patients who explore HIPEC surgery are typically those for whom systemic chemotherapy alone has been insufficient, or in whom disease is confined to the peritoneal cavity without distant spread to the lungs, liver parenchyma beyond limited resectable lesions, or bones.

Step-by-Step: What Happens During the HIPEC Procedure

1. Pre-operative assessment: CT/MRI staging, performance status scoring, nutritional assessment, and anaesthesia review to confirm you can safely tolerate a long operation.
2. General anaesthesia & cytoreductive surgery (CRS): You are placed under general anaesthesia. The surgeon makes a large midline incision and methodically removes all visible tumour deposits – this may involve removing sections of bowel, the omentum, the spleen, or other affected structures. This phase can take 4 to 6 hours.
3. HIPEC infusion: Catheters are placed through small incisions. The machine warms the chemotherapy solution (commonly cisplatin, mitomycin-C, or oxaliplatin) to approximately 41-43°C and pumps it into the abdomen for 60 to 90 minutes while body temperature is carefully monitored.
4. Drainage & closure: The chemotherapy solution is completely drained. The surgical team closes the abdomen and you are transferred to the ICU for close monitoring.
5. ICU & ward recovery: Most patients spend 1–3 days in the ICU, followed by a ward stay of 5–10 days before discharge.

HIPEC Surgery Survival Rate and Outcomes

HIPEC surgery survival outcomes vary significantly depending on cancer type, extent of peritoneal spread, completeness of cytoreduction, and the patient’s overall health. That said, published data consistently demonstrate that hyperthermic intraperitoneal chemotherapy combined with cytoreductive surgery produces substantially better survival outcomes than systemic chemotherapy or supportive care alone in appropriately selected patients.

For colorectal peritoneal cancer surgery, research has recorded a median overall survival of over 54 months in HIPEC-treated patients versus just 24.5 months in those managed without HIPEC – a near doubling of survival time. In ovarian cancer, the landmark OVHIPEC-1 trial demonstrated a 12-month improvement in overall survival when HIPEC was added to interval debulking surgery, without increasing serious complications.

It is important to understand that HIPEC surgery is not a cure for every patient. Its goal is disease control, quality-of-life preservation, and maximising survival duration. The expertise of the operating surgeon and the technology of the centre performing the procedure also play a crucial role in outcomes. The oncology care specialists at SPARSH Hospitals – Global Care bring advanced training and multidisciplinary support to every peritoneal cancer surgery case.

HIPEC Surgery Recovery Time and Side Effects

Given that the HIPEC procedure is a major surgery often lasting 6 to 10 hours in total, the recovery period is longer than that of most standard abdominal operations. Understanding what to expect helps patients and families plan ahead and reduces anxiety around the process.

Recovery Timeline

• Days 1-3 (ICU): Close haemodynamic monitoring, IV nutrition, pain management, and fluid balance management. A nasogastric tube and urinary catheter are standard.
• Days 4-10 (Ward): Gradual return to oral intake, physiotherapy begins, short walks. Bowel function typically returns within 3-5 days.
• Weeks 2-6 (Home recovery): Fatigue is common. Patients should avoid lifting heavy objects for 6-8 weeks. Wound care and follow-up appointments are essential.
• 1-3 months: Most patients return to light activities. Full recovery, including return to pre-surgery energy levels, may take up to 12 months for some individuals.

Potential Side Effects

Because HIPEC surgery involves both an extensive surgical procedure and direct chemotherapy exposure, side effects can arise from either component. The medical team at SPARSH Hospitals – Global Care monitors patients closely throughout the entire perioperative period to identify and manage complications early.

It’s worth noting that while the procedure carries meaningful risks, the complication rates at experienced, high-volume centres like SPARSH Hospitals – Global Care are managed with structured perioperative protocols and specialist nursing teams. The decision to proceed is always made on a patient-specific risk-benefit analysis.
