-
Implications of Child Pugh criteria?
- • Major surgeries can be done only in Class AQ
- • Only minor surgical procedures can be performed in Class BQ
- • No surgical intervention should be done in Class C (Best treatment is liver transplantation)Q
-
• Shunt surgery is considered only in patients with preserved hepatic function (CTP class A)Q
• TIPS is used in patients with decompensated liver disease (CTP class B or C)Q.
-
Modifications of Sengstaken and Blakemore tube?
- Sengstaken and Blakemore tube - triple-lumenQ

Protected by placement of an endotracheal tubeQ.
-
Volume of balloon in Sengstaken–Blakemore tube?
- Gastric balloon is inflated with with 300 ml of airQ
- If bleeding does not stop promptly, esophageal balloon may be inflated to a pressure of 40 mm HgQ.
-
Mechanism of vitamin A induced Hepatotoxicity?
- • Excess vitamin A is stored in stellate cellsQ in the liver and accumulation can lead to their activation and hypertrophy, excess collagen production, fibrosisQ and liver injury.
- Liver biopsy is diagnosticQ
-
Porto-Systemic Anastomosis in Esophageal varices?
Left gastric veinQ - Azygous veinQ and accessory hemiazygous vein
-
Porto-Systemic Anastomosis in Rectum and anal Canal?
Superior rectal veinQ - Middle and inferior rectal veinQ
-
Porto-Systemic Anastomosis in Umbilicus?
Left branch of portal vein (paraumblical branches) - Superficial (superior and inferior) epigastric veinsQ
-
Porto-Systemic Anastomosis in Posterior abdominal wall?
Colic and omental veinsQ - Retroperitoneal veinsQ of abdominal wall, renal capsule, splenic and hepatic flexure

What is Model for End-Stage Liver disease (ME LD) Score?
- • MELD score is used to assess the severity of chronic liver diseaseQ
- • It was initially developed to predict death within 3 months of surgery in patients that had undergone TIPS.Q
- • It is calculated by using 3 variables (CBI): S. Creatinine, S. Bilirubin, INRQ [@ CBI]

-
Role of antibiotics in UGI bleeding?
- • Cirrhotic patients with variceal bleeding have a high risk of developing bacterial infectionsQ
- • Bacterial infections are associated with rebleeding and a higher mortality rateQ.
