Q

what is a Frey procedure?

A

coring out diseased portion of pancreatic head with longitudinal dissection of pancreatic duct toward the tail and then lateral pancreaticojejunostomy for chronic pancreatitis

Q

What is a Beger procedure?

A

duodenum preserving pancreatic head resection
uses 2 anastomoses with RNY jejunal loop to pancreatic tail remnant (end to side) and to the excavated pancreatic head (side to side)

For patients with a large inflammatory mass in the head with no evidence of distal ductal dilation – makes the end to side PJ the most appropriate anastomosis

Q

what are the 4 types of acute pancreatitis complications per the revised Atlanta classification?

Q

How to manage a pseudocyst?

A

supportive for 4-6 weeks

if no resolution, wait until thick fibrous wall and do internal cyst drainage via open or endoscopic cystgastrostomy, cystojejunostomy, or cystuodenostomy

always perform biopsy to r/o malignancy

external drainage can be done for infected collections of pseudocysts
