  1. Biliary Pathology

  2. Liver Biliary tree Gallbladder

  3. RPC Acute cholecystitis Empyema of gallbladder Mucoceal of gallbladder Cholangitis Pancreatitis

  4. Biliary Patholgy • History and Examination • Previous biliary surgery • Previous history of biliary pathology • Epigastic / RUQ pain • Duration of pain • Associate symptoms / signs • E.g. Tea color urine, jaundice, stool color… • Vital signs • Pulse, resp rate, blood pressure, temperature • Toxic or not ?? • X rays • Abdominal supine x ray • Gallstone • Aerobilia • CXR --- right side pleural effusion • Blood test • WCC, LFT, amylase ECG

  5. Aerobilia

  6. Acute cholecystitis

  7. Acute cholecystitis • Blockage of cystic duct • Tissue oedema …. Ischaemia … infection • Ultrasound abdomen • Thickened gallbladder wall • Sonographic murphy’s sign • Pericholecystic fluid • Gallstone • Conservative Vs Early Lap +/- open cholecystectomy Vs Cholecystostomy • Medical / GA risk of the patient

  8. Acute Cholecystitis • Ultrasound abdomen • Thickened gallbladder wall • Pericholecystic Fluid • Sonographic murphy sign • Also look at: • Free fluid • CBD size / CBD stone • Gallstones

  9. Acute Cholecystitis • Early Vs Delay Cholecystectomy • Medical risk too high for GA operation • Precutaneous Cholecystostomy • Decompress the gallbladder • Drain infected bile / pus • Still require antibiotic

  10. Precutaneous Transhepatic Cholecystostomy

  11. Cholecystostomy • Decompress the gallbladder • Observe for improvement • Continue deterioration • ? Perforated gallbladder – urgent operation • Tube blocked • Drain content and amount • Bile production approx 500mls per day • Mucous only – blocked cystic duct • Lots of bile (500mls or above) – CBD stone • Check cholecystogram • Tube position • Position of stone in gallbladder (cystic duct still obstructed ?) • Cholangiogram (any CBD stone… drop stone) • Definitive Rx plan • Lap cholecystectomy • Conservative Rx / Removal of tube

  12. Cholecystogram

  13. Cholangitis Cholangitis

  14. Fever RUQ pain Jaundice +/- Confusion Biliary Decompression Need to check clotting profile Vit K IV 10mg daily Antibiotics Definitive Mx Aim to remove causative factors Cholangitis Charcot’s triad • Assess patient clinical status • Vital parameters • Resuscitation Biliary decompression Ultra-urgent Vs urgent/early

  15. Biliary decompression • ERCP • Endoscopic retrograde cholangiopancreatogram • PTBD • Percutaneous transhepatic biliary drainage • ECBD • Exploration of common bile duct

  16. ERCP

  17. Internal stent

  18. ERCP not suitable

  19. ERCP with previous B1 gastrectomy

  20. ERCP with previous B2 gastrectomy Definitely higher risk of perforation

  21. Cholangitis • What if ERCP failed ?? • Anatomical problem • Technical difficulties • Patient condition poor • Respiratory problem • Severe sepsis / MOF

  22. Percutaneous Transhepatic Biliary Drainage External PTBD

  23. External PTBD Right side system

  24. Percutaneous Transhepatic Biliary Drainage • Under LA, interventional radiological procedure • Risks • Contrast allergies, Local anaesthetic agents allergies • Liver laceration, bleeding, traumatic tapping • NOT suitable in patient with marked ascites • Tube complications • Kinking, blockage, dislodgement • Patient usually spike high fever after procedure • Need injection of contrast into biliary tree --- bacteraemia

  25. Percutaneous Transhepatic Biliary Drainage • External PTBD • Right or left system ? • Usually communicable except in case of tumour • Usually external PTBD at initial stage • Short procedure time, less manipulation • Aim is to decompress the biliary system • Internal – external PTBD • Aim to direct bile into duodenum • Need better cholangiogram first (therefore wait till 1 wk after inflammation settle and edema subside) • Lost of fluid, electrolytes • Able to disconnect the bed side bag • Allow future ERCP (two hand technique) if initial ERCP failed due to difficult cannulation

  26. Internal – external PTBD

  27. Internal-external PTBD

  28. ERCP two hand technique Internal – external PTBD ERCP

  29. Percutaneous Transhepatic Biliary Drainage • Monitor patient progress • Vital signs • Clinical signs • Drainage amount and content • Suspect blockage revision? • Definitive Management Plan • Surgery • Trans PTBD dilatation and removal of CBD stone

  30. Remember to use correct antibiotic Send for Timing of biliary decompression is crucial Cholangitis can be quickly lethal especially in elderly Need accurate clinical assessment and appropriate treatment

  31. Recurrent Pyogenic Cholangitis L R

  32. ERCP of a case of RPC Stones

  33. RPC • Appropriate antibiotic • According to previous bile culture • Depends on the disease distribution • Peripheral and / or Central • Decompression of biliary system • Definitive Treatment • Exploration of common bile duct +/- drainage procedure • Choledochoduodenostomy • Choledochojejunostomy • Liver segmentectomy

  34. RPC • Before definitive procedure • Need to correctly assess • Biliary drainage and function of the liver • Accurate assessment of the distribution of the disease • CT abdomen • EHIDA scan

  35. RPC Right Lobe CT

  36. RPC Left lobe

  37. RPC • Definitive treatments Vs conservative Plan • Need to BALANCE the risk of OT and the problems of disease process • Disease process • Recurrent attack • Liver abscess formation • Cholangiocarcinoma

  38. End of Topic
