Questions on Bile ducts?

 Ans b

"Poncho trial " answers this question of timing of cholecystectomy in biliary pancreatitis 

Early cholecystectomy (just before discharge, when the patient has recovered and severe disease excluded), compared to interval cholecystectomy, effectively reduces---

  1. The rate of recurrent gallstone-related complications in patients with mild biliary pancreatitis,
  2. low added risk of complications.

Evidence on the timing of cholecystectomy in severe pancreatitis is scarce. Cholecystectomy is recommended after all signs of pancreatic necrosis have been resolved or if they persist more than 6 weeks

  • Cholecystectomy during the same admission is recommended for patients with mild biliary pancreatitis to prevent recurrent attacks.
  • In cases of severe pancreatitis, surgery is generally delayed until the inflammation subsides.
  • Studies have shown that early cholecystectomy during the same admission for mild to moderate biliary pancreatitis does not increase complications compared to delayed or interval cholecystectomy.

Blood supply of CBD

by

Q) Supraduodenal  CBD is supplied by all except (AIIMS NOV 18)
a Cystic art
b RHA
c LHA
d Anterosuperior pancreaticoduodenal artery

 

Ans c

The blood supply to the right and left hepatic ducts and upper portion of the CHD is from the CA and the right and left hepatic arteries.

The supraduodenal bile duct is supplied by arterial branches from the right hepatic, cystic, posterior superior pancreaticoduodenal, and retroduodenal arteries.

arteries to the supraduodenal bile duct run parallel to the duct at the 3 and 9 o’clock positions.

Approximately 60% of the blood supply to the supraduodenal bile duct originates
inferiorly from the pancreaticoduodenal and retroduodenal arteries

whereas 38% of the blood supply originates superiorly from the right hepatic artery and CD artery
