Hepatobiliary surgery is a specialized field of surgery that encompasses a broad scope of conditions, diseases, treatments, and procedures related to the liver, gallbladder, bile ducts, and pancreas. Hepatobiliary experts are highly skilled in diagnosing, managing, and surgically treating various liver diseases, including cirrhosis, hepatitis B and C, and fatty liver disease. They also address liver tumors such as hepatocellular carcinoma (HCC) and cholangiocarcinoma, as well as gallbladder diseases like gallstones and gallbladder cancer. In addition, hepatobiliary surgeons manage diseases of the bile ducts, such as biliary strictures and choledocholithiasis, and pancreatic conditions like pancreatitis and pancreatic tumors. With their expertise, hepatobiliary surgeons employ a range of treatments and procedures, including cholecystectomy, liver resection, biliary reconstruction, and pancreatic surgery, to provide comprehensive care for patients with hepatobiliary disorders.
Scope: Conditions, Diseases, Treatments, and Procedures
Liver Diseases:
Cirrhosis: Hepatobiliary experts manage cirrhosis by addressing the underlying causes, such as alcohol abuse or viral hepatitis, and providing supportive care. They may recommend lifestyle modifications, including alcohol cessation and a healthy diet. In advanced cases, liver transplantation may be considered.
Hepatitis B: Hepatobiliary surgeons collaborate with hepatologists to manage hepatitis B. They may prescribe antiviral medications to suppress viral replication and monitor liver function. In severe cases, liver transplantation may be necessary.
Hepatitis C: Hepatobiliary surgeons work closely with hepatologists to manage hepatitis C. They may prescribe antiviral therapy to eradicate the virus and monitor liver function. In cases of advanced liver disease, liver transplantation may be considered.
Fatty liver disease: Hepatobiliary experts manage fatty liver disease by addressing the underlying risk factors, such as obesity, diabetes, and high cholesterol. They may recommend lifestyle changes, including weight loss, regular exercise, and a healthy diet. Medications and close monitoring of liver function may be necessary in some cases.
Liver cysts: Hepatobiliary surgeons evaluate liver cysts to determine if intervention is required. They may perform cyst drainage using imaging guidance or recommend surgical removal if the cysts are symptomatic, large, or causing complications.
Liver abscess: Hepatobiliary experts manage liver abscesses by draining the abscess and administering appropriate antibiotic therapy. They may perform percutaneous or surgical drainage procedures, depending on the size and location of the abscess.
Liver Tumors:
Hepatocellular carcinoma (HCC): Hepatobiliary surgeons play a crucial role in managing HCC. Treatment options depend on the stage and extent of the tumor. They may perform surgical resection to remove the tumor if it is localized. In advanced cases, liver transplantation, ablation techniques (such as radiofrequency ablation or microwave ablation), transarterial chemoembolization (TACE), and systemic therapies like targeted therapy or immunotherapy may be considered.
Cholangiocarcinoma: Hepatobiliary surgeons manage cholangiocarcinoma through a multidisciplinary approach. Surgical resection, including liver resection and bile duct resection, is the primary treatment for localized tumors. Liver transplantation may be an option for select cases. Adjuvant therapies such as radiation therapy or chemotherapy may be recommended before or after surgery.
Liver metastases from other cancers: Hepatobiliary surgeons assess the extent and location of liver metastases to determine the appropriate treatment approach. They may perform surgical resection if the metastases are limited and resectable. Ablation techniques, such as radiofrequency or microwave ablation, may be used for smaller metastases. Systemic therapies like chemotherapy or targeted therapy may also be recommended in combination with surgical interventions.
Benign liver tumors (e.g., hemangioma, adenoma): Hepatobiliary surgeons assess benign liver tumors based on their size, location, and symptoms. In certain cases, observation and monitoring may be sufficient. However, if the tumor is causing significant symptoms, enlarging, or potentially malignant, surgical resection or ablation techniques may be considered.
Gallbladder Diseases:
Gallstones (cholelithiasis): Hepatobiliary surgeons commonly perform cholecystectomy (gallbladder removal) to manage symptomatic gallstones. The surgery can be performed using laparoscopic or open techniques. Laparoscopic cholecystectomy is the preferred approach due to its minimally invasive nature, resulting in faster recovery and less scarring.
Cholecystitis (inflammation of the gallbladder): In acute cases of cholecystitis, hepatobiliary surgeons may recommend urgent cholecystectomy to remove the inflamed gallbladder. In chronic or recurrent cases, elective cholecystectomy may be performed to prevent further complications.
Gallbladder polyps: Hepatobiliary surgeons evaluate gallbladder polyps to determine their risk of malignancy. Polyps larger than 1 cm or showing suspicious features may require surgical removal through cholecystectomy to prevent potential cancer development.
Gallbladder cancer: Hepatobiliary surgeons play a critical role in the surgical management of gallbladder cancer. The recommended treatment is radical cholecystectomy, which involves removing the gallbladder, associated lymph nodes, and nearby tissues. Biliary reconstruction may be necessary to restore bile flow after gallbladder removal.
Bile Duct Diseases:
Biliary strictures: Hepatobiliary surgeons manage biliary strictures by performing surgical interventions to restore normal bile flow. These procedures may involve biliary reconstruction, using either the patient's own tissues or artificial materials, to bypass or repair the narrowed or obstructed bile ducts.
Biliary stones (choledocholithiasis): Hepatobiliary surgeons employ various techniques to manage biliary stones. Endoscopic methods, such as endoscopic retrograde cholangiopancreatography (ERCP), can be used to remove stones or place stents to relieve obstructions. Surgical common bile duct exploration may be necessary in complex cases.
Biliary atresia: Hepatobiliary surgeons manage biliary atresia in newborns through surgical intervention called the Kasai procedure. This procedure aims to establish bile flow by connecting the liver to the small intestine. In severe cases where the procedure is unsuccessful or complications arise, liver transplantation may be considered.
Primary sclerosing cholangitis (PSC): Hepatobiliary surgeons manage PSC by addressing symptoms, managing complications, and monitoring disease progression. Biliary drainage procedures, such as endoscopic stenting or surgical bypass, may be performed to relieve obstructions. Liver transplantation may be considered in advanced cases or when liver failure occurs.
Biliary tract infections (cholangitis): Hepatobiliary surgeons manage cholangitis by addressing the underlying cause and providing appropriate treatment. Biliary drainage procedures are performed to relieve obstructions and improve bile flow. Antibiotics are administered to treat the infection and prevent complications.
Pancreatic Diseases:
Pancreatitis (acute and chronic): Hepatobiliary surgeons manage pancreatitis through a combination of medical management, supportive care, and surgical interventions. In severe cases with complications such as infected necrosis or pseudocysts, surgical drainage procedures may be necessary. For chronic pancreatitis, hepatobiliary surgeons may perform pancreatic resection or other procedures to alleviate symptoms and improve quality of life.
Pancreatic cysts: Hepatobiliary surgeons evaluate pancreatic cysts to determine their nature and risk of malignancy. Small and asymptomatic cysts may be observed. However, larger cysts causing symptoms or with concerning features may require endoscopic or surgical drainage or even resection, depending on the specific characteristics and location of the cysts.
Pancreatic pseudocysts: Symptomatic or complicated pancreatic pseudocysts may require drainage procedures. Hepatobiliary surgeons may perform endoscopic cyst-gastrostomy or percutaneous catheter drainage to remove or treat the pseudocysts. In some cases, surgical intervention or resection may be necessary.
Pancreatic neuroendocrine tumors (PNETs): Surgical management of PNETs is a key aspect of treatment. Hepatobiliary surgeons assess the size, location, and stage of the tumor to determine the appropriate surgical approach. This may involve tumor resection, either partial or complete, with preservation of pancreatic function and consideration of lymph node removal.
Pancreatic adenocarcinoma (a type of pancreatic cancer): Hepatobiliary surgeons are involved in the surgical management of pancreatic cancer. Surgical procedures for pancreatic adenocarcinoma include pancreaticoduodenectomy (Whipple procedure) for tumors located in the head of the pancreas, distal pancreatectomy for tumors in the body or tail, and total pancreatectomy for extensive disease. They may also perform palliative surgical interventions to alleviate symptoms and improve quality of life in advanced cases.
The specific treatment and management approach for each condition or disease depend on individual patient factors, disease stage, and other considerations. Hepatobiliary experts evaluate the specific condition and develop tailored treatment plans to optimize patient outcomes.
Qualifications, Training, and Certifications
Becoming a hepatobiliary surgeon requires a physician to complete a five-year residency in general surgery. Thereafter, the surgeon needs to complete fellowship in hepatobiliary surgery, with the duration typically ranging from one to two years.
