Liver, Bile Duct and Pancreas Disease

Liver, Bile Duct and Pancreas Disease

Liver and Bile Duct Surgery Program

Mount Sinai South Nassau's Liver and Bile Duct Surgery Program, headed by Ganesh Gunasekaran, MD, routinely treats patients with complex benign tumors, malignant cancers and other disorders of the liver, gallbladder, bile duct and pancreas.

The program’s experienced, board certified and fellowship-trained hepatobiliary and hepatopancreatobiliary (HPB) surgeons use the latest technology and minimally invasive techniques and work in conjunction with other specialists to provide patients with a multidisciplinary approach to care.

Conditions We Treat

  • Bile Duct Cancer (Cholangiocarcinoma)
  • Gallbladder Cancer
  • Liver Cancer (Hepatocellular Carcinoma)
  • Metastatic Liver Tumors (Colorectal Cancer)
  • Benign Liver Tumors

Procedures We Offer

  • Liver Resection
    A liver resection, or hepatectomy, is a surgical procedure to remove part of your liver. You can have up to two-thirds of your liver removed if the rest of your liver is healthy. If you have liver disease, you may have a smaller portion removed. Your liver can grow back and if your remaining liver is healthy, it will grow back to its former size.
  • Minimally Invasive Liver Surgery
    Minimally invasive surgery are procedures done with small incisions (cuts). This method reduces side effects and helps you recover faster. There are minimally invasive procedures for primary liver cancer, such as ablation, NanoKnife®, or embolization.  
  • Bile Duct Resection, including Cholecystectomy
    Bile duct resection is surgery that removes your gall bladder and bile duct outside the liver. Your surgeon then reconnects your liver and intestine. After this surgery, bile will be able to flow freely from your liver into your intestine to help you digest food.
  • Hepatic Artery Infusion Pump
    Hepatic Artery Infusion is a type of regional chemotherapy to treat advanced colorectal cancer that has spread to the liver. It delivers a high dose of chemo directly into the liver's blood supply using a pump that surgeons implant under your skin.
  • Ablation (Laparoscopic or Percutaneous Approach)
    Ablation is treatment that destroys liver tumors without removing them. These techniques can be used in patients with a few small tumors and when surgery is not a good option (often because of poor health or reduced liver function).
