Other Major Surgery 

1. Multivisceral resection (MVR)

is a complex surgical procedure where two or more organs or structures are removed simultaneously to completely excise cancer. It is performed when a tumor has invaded multiple adjacent organs, making simple resection insufficient for complete cancer removal.

 

When is Multivisceral Resection Used?

MVR is typically done for locally advanced cancers that have spread beyond the primary organ but have not metastasized to distant sites. It is commonly used for cancers such as:

• Colorectal cancer invading nearby structures (e.g., bladder, uterus, small intestine)

• Gastric (stomach) cancer with local extension

• Pancreatic cancer affecting nearby vessels or organs

• Retroperitoneal sarcomas (soft tissue tumors in the abdomen)

• Ovarian or uterine cancer with spread to intestines or bladder

​

​

2. Peritonectomy

is a surgical procedure in which part or all of the peritoneum (the thin membrane lining the abdominal cavity and covering the abdominal organs) is removed. This procedure is usually performed to treat cancers that have spread within the abdominal cavity, especially peritoneal carcinomatosis (cancer affecting the peritoneum).

​

Why is Peritonectomy Performed?

Peritonectomy is commonly used for patients with peritoneal surface malignancies, including:

• Peritoneal carcinomatosis (cancer spread to the peritoneum from other organs)

• Pseudomyxoma peritonei (rare mucus-producing tumor)

• Mesothelioma of the peritoneum

• Ovarian cancer with peritoneal spread

• Colorectal or gastric cancer that has spread to the peritoneum

​

​

3. Intra-abdominal soft tissue tumors / Sarcomas

\Intra-abdominal soft tissue tumors are abnormal growths that develop in the connective tissues (muscles, fat, blood vessels, or nerves) inside the abdominal cavity. These tumors can be benign (non-cancerous) or malignant (cancerous, known as sarcomas).

 

What Are Sarcomas?

Sarcomas are rare cancers that arise from soft tissues or bones. When they occur in the abdomen, they are called intra-abdominal sarcomas.

​

Types of Intra-Abdominal Sarcomas

• Gastrointestinal Stromal Tumor (GIST)

• Liposarcoma

• Leiomyosarcoma

• Desmoid Tumor (Aggressive Fibromatosis)

• Synovial Sarcoma & Other Rare Sarcomas

4. Liver/ Biliary / Pancreas surgeries requiring vascular resection and reconstruction

Liver and biliary surgery refers to surgical procedures performed on the liver, gallbladder, and bile ducts to treat various conditions, including tumors, infections, blockages, and organ failure. These surgeries range from minimally invasive to complex open procedures, depending on the disease.
