  1. What is Pringle Maneuver (Total Inflow Occlusion)?
    • Total clamping of the hepatic pedicle, by placing an atraumatic clamp across the foramen of WinslowQ.
    • • Appropriate-sized vascular clamp or loop snare easily controls hemorrhage from either the portal vein or the hepatic arteriesQ.
    • • Inflow occlusion durations of up to 30 minutes can be tolerated safely in cirrhotic livers and possibly up to 60 minutes in early disease. • If prolonged occlusion is required, intermittent clamping can be used with repeated clampings of 10-20 minutes duration, each followed by 5 minutes declamping.
  2. What is Trisegmentectomy?
    • Right trisegmentectomy or extended right hepatectomy: Complete resection of segment IV with the right liver (removal of segment IV, V, VI, VII, VIII) Q.
    • Left trisegmentectomy or extended left hepatectomy: Complete resection of segments V and VIII with the left liver (removal of segment II, III, IV, V, VIII)
  3. What is duration of Liver Regeneration?
    Following resection of 2/3rd of the liver, regeneration is complete within 5-6 months.
  4. MC organ injured in blunt abdominal trauma?
    Spleen > liverQ
  5. Most common organ injured in penetrating abdominal injuries?
    small bowel (38%) > colon (31%)Q > , liver (28%)
  6. Most common segments involved in liver injury?
    • 6, 7 and 8 of the liverQ.
    • Lver injury bleeding is venous Q; and therefore low pressure, tamponade is readily performed
  7. Conservative criteria for non-operative management in lier injury?
    • Hemodynamically stable patientQ
    • No peritoneal signs on examinationQ
    • Absence of other major injuriesQ
  8. MC complication of severe liver injury in patients who undergo operationQ?
    Liver parenchymal necrosis
  9. MC complication of non-operative management of liver injury?
  10. Management of Deep Liver Laceration?
    Opening the liver wound and directly approaching the bleeding vessel, a procedure known as tractotomyQ.
  11. Management of Penetrating Liver Tracts?
    Tractotomy or tamponade using a balloon catheterQ
  12. Management of Injuries in the vicinity of retrohepatic IVC?
    Packing alone, without operative exploration Q
  13. Management of Retrohepatic IVC Injury?
    Atriocaval shunt (Shrock shunt)Q
