Study Notes
Biliary Anatomy
- Triangle of Calot serves as a surgical landmark for cholecystectomy.
- Key structures in the 3 C’s: Common Hepatic Duct (CHD), Cystic Duct, Cystic Artery.
- Common hepatic duct connects left and right biliary ducts, supplying blood via the cystic artery.
- Sphincter of Oddi regulates flow between the common bile duct and pancreatic duct.
Celiac Axis
- Major abdominal artery originating from the abdominal aorta.
- Three main branches include Left Gastric, Splenic, and Common Hepatic Arteries.
Gallbladder Function
- Located behind the liver, it concentrates and stores bile (capacity: 40-70 mL).
- Bile release occurs in the duodenum to aid digestion; blood supply via cystic artery.
Perioperative Considerations
- General anesthesia is standard, with either open or laparoscopic approaches.
- Supine position is common, necessitating maintenance of blood loss precautions.
Surgical Counts
- Initial and Closing Counts classified as Major for open surgeries, Minor for laparoscopic.
Surgical Interventions
- Common biliary surgeries include Cholecystectomy (gallbladder), Splenectomy (spleen), and liver procedures such as Hepatic Resection and Transplant.
ERCP (Endoscopic Retrograde Cholangiopancreatography)
- Diagnostic procedure for biliary tract issues; scope inserted through the mouth into the duodenum.
- Involves injecting contrast dye to visualize blockages in the biliary tree.
Cholangiogram
- Conducted intraoperatively to identify blockages; identifies stones via contrast injection into cystic duct.
- Choledocholithotomy involves incision of the common bile duct for stone removal.
Cholecystectomy
- Removal of the gallbladder for chronic inflammation or gallstones; 90% laparoscopic approach.
- Key surgical tools include GIA staplers, silk and vicryl ties, and GI sutures.
Pancreatic Transplant
- Performed for Type 1 Diabetes patients; includes three options: PTA, SPK, and PAK.
- Aims to prevent diabetic complications, with lifelong immunosuppressants post-op.
Spleen Anatomy and Function
- Located in the upper left quadrant, protected by ribs; crucial for blood filtration and immune response.
- Blood supply delivers from the aorta through the celiac axis to the splenic artery.
Splenectomy
- Indicated for trauma, malignancies, hemolytic jaundice, and infections.
- Equipment varies between open and laparoscopic approaches, requiring blood replacement and hemostatic agents.
Liver Anatomy
- Found in the right upper quadrant, involved in metabolism of carbohydrates, proteins, and fats.
- Composed of functional lobules containing hepatic ducts and portal vessels.
Hepatic Resection
- Resection aims to remove tumors, requiring meticulous hemostasis and intraoperative imaging for tumor identification.
Liver Transplant
- Implantation of donor liver from either cadaveric or living donors, indicated for liver diseases like cirrhosis.
- Involves anastomosis of hepatic vessels and restoration of blood flow for proper function.
Organ Donation Procedures
- Governed by the Trillium Gift of Life Network; necessitates signed consent from the legal next of kin for organ donation.
- Organ recipients may come from neurological determination of death (NDD) or after circulatory death (DCD).
Aseptic Technique
- Critical maintenance of aseptic technique is emphasized throughout surgical procedures to prevent contamination and infection.
