HIPEC Surgery

1. Treatment Overview

The Smart T Web Hospital is proud to offer HIPEC (Hyperthermic Intraperitoneal Chemotherapy) surgery, one of the most advanced treatments for peritoneal cancers. This revolutionary procedure combines cytoreductive surgery with heated chemotherapy delivered directly to the abdomen, providing hope for patients with previously considered incurable peritoneal surface malignancies.

Since establishing our surgical oncology program in 2012, we have become Gujarat's leading center for complex oncological procedures. Our HIPEC program represents the pinnacle of surgical innovation, combining the expertise of our multidisciplinary team with state-of-the-art technology to deliver optimal outcomes for our patients.

2. What is HIPEC Surgery

2.1 Understanding HIPEC

HIPEC (Hyperthermic Intraperitoneal Chemotherapy) is an innovative treatment that combines two powerful cancer-fighting approaches:

• Cytoreductive Surgery (CRS): Surgical removal of all visible cancer from the peritoneal cavity
• Heated Chemotherapy: Direct application of heated chemotherapy drugs to the abdominal cavity
• Hyperthermia: Use of elevated temperature (42-43°C) to enhance drug penetration
• Direct Delivery: Chemotherapy delivered directly to cancer site
• Localized Treatment: Minimizes systemic toxicity

2.2 Scientific Principles

The effectiveness of HIPEC is based on several scientific principles:

• Hyperthermia Enhancement: Heat increases drug penetration into tissues
• Direct Cytotoxicity: Heat itself has cancer cell killing properties
• Pharmacokinetic Advantage: High local concentration with low systemic absorption
• Peritoneal Barrier: Peritoneum acts as barrier preventing systemic distribution
• Synergistic Effect: Combined effect greater than sum of individual treatments

2.3 Historical Development

HIPEC has evolved over decades of research and clinical development:

• First developed in the 1980s for peritoneal mesothelioma
• Expanded to colorectal and ovarian cancers
• Continuous refinement of techniques and protocols
• Growing worldwide adoption and experience
• Ongoing research into new applications
