Study Notes
Biliary Surgery Overview
- Biliary surgery involves the gallbladder, pancreas, spleen, and liver anatomy.
- Understanding the indications and procedural considerations is crucial for various biliary surgeries.
- In Canada, organ transplantation processes are governed by established protocols.
Biliary Anatomy
- Triangle of Calot is a key surgical landmark for cholecystectomy, consisting of:
- Common Hepatic Duct (CHD)
- Cystic Duct
- Cystic Artery
- Common hepatic duct connects left and right biliary ducts, with blood supply from cystic artery (branch of hepatic artery).
- Sphincter of Oddi regulates the flow into the duodenum.
Gallbladder
- Located at the back of the liver, it stores bile (40-70 mL capacity) to aid digestion.
- Blood supply through cystic artery from the hepatic artery.
Surgical Factors
- General anesthesia is standard; procedures can be open or laparoscopic.
- Supine position is typically utilized for surgery.
- Blood loss management is integral, especially for scrub nurses.
Surgical Interventions
- Cholecystectomy (gallbladder removal)
- Splenectomy (spleen removal)
- ERCP (Endoscopic Retrograde Cholangiopancreatography) used for diagnosing biliary tract issues.
- Liver interventions include hepatic resection, liver transplant, and pancreatic transplant.
Endoscopic Retrograde Cholangiopancreatography (ERCP)
- Used to diagnose biliary tract problems via scope inserted through the mouth.
- Catheter connects to the common bile duct for x-ray guided imaging and contrast dye application.
Cholecystectomy
- Performed open or laparoscopically for chronic inflammation or cholelithiasis (gallstones).
- Approximately 90% are done laparoscopically.
- Overall process remains consistent once abdominal entry is achieved.
Pancreatic Transplant
- Options include:
- Pancreas Transplant Alone (PTA)
- Simultaneous Pancreas-Kidney Transplant (SPK)
- Pancreas After Kidney Transplant (PAK)
- Lifelong immunosuppressants are required post-transplant to prevent rejection.
Spleen Anatomy and Function
- Spleen is located in the upper left quadrant (ULQ) and is crucial for filtering blood and immune function.
- Blood supply from the aorta and celiac axis, connected to the splenic artery and vein.
Splenectomy
- Indicated for trauma, malignancies, infections, and other conditions.
- Careful blood supply management is essential during the procedure.
Liver Anatomy and Function
- Right upper quadrant organ responsible for carbohydrate, protein, and fat metabolism.
- Lobules are functional units containing portal triads and Kupffer cells for immune response.
Hepatic Resection
- Performed for tumor removal, requiring careful hemostatic measures during surgery.
Liver Transplantation
- Involves re-anastomosing donor liver vessels to restore blood flow.
- Main diseases necessitating liver transplant include hepatic cancer, cirrhosis, and biliary atresia.
Organ Donation
- Organ donations are operated under stringent protocols via the Trillium Gift of Life Network.
- Types of donors include Neurological Determination of Death (NDD) and After Circulatory Death (DCD).
- Maintenance of aseptic technique is crucial throughout the process.
