Emphysematous cholecystitis. what cultures?

cultures with gas forming Ecoli, clostridia

Emphysematous cholecystitis. treatment?

Emergent cholecystectomy broad abs with clostridium coverage (eg ampicillin-sulbactam).

Acalculous cholecystitis. Never had a gallbladder disease before. Diagnosis by a high degree of suspicion and imaging studies.

Acalculous cholecystitis. risk factors?

Severe trauma or recent surgery Prolonged fasting or TPN Critical illness (sepsis, ICU)

Acalculous cholecystitis. clinical?

Fever, leukocytosis, incf. LFTs, RUQ pain Jaundince and RUQ mass is less common

Acalculous cholecystitis. diagnosis?

US preffered HIDA or CT if needed

Acalculous cholecystitis. treatment?

Enteric abs coverage Cholecystostomy for initial drainage Cholecystectomy one clinically stable

Management of gallstones. stones without symptoms?

No treatment required in most patients

Management of gallstones. stones with typical biliary colic symptoms? 2

elective laparoscopic cholecystectomy possible ursodeoxycholic acid in poor surgical candidates

Management of gallstones. complicated gallstone disease * *acute cholecystitits, choledocholithiasis, gallstone pancreatitis.

cholecystectomy within 72 h

what in included in complicated gallstone disease?

*acute cholecystitits, choledocholithiasis, gallstone pancreatitis.

Postcholecystectomy syndrome. when manifests?

Postoperative (early) or months to years (late) after cholecystectomy.

Postcholecystectomy syndrome. due to 2 groups of reasons?

Can be due to biliary (retained CBD or cystic duct stone, biliary dyskinesia) OR extra-biliary (pancreatitis, PUD, CAD). Sphincter of Oddi dysfunction; either stenosis or dyskinesia (SOD). Can be triggered by opioid medication (morphine).

Postcholecystectomy syndrome. CP?

Persistent abdominal pain. Dyspepsia.

Postcholecystectomy syndrome. labs? transferazes visokios

Elevated ALP. Abnormal aminotransferases. Dilated CBD on abdominal US. SOD --> SOD manometry. SOD = stenosis or dyskinesia

Postcholecystectomy syndrome. management?

Endoscopic US, ERCP, or MRCP. Directed at causative agent. SOD --> sphincterotomy.

Choledolithiasis. definition?

stone in common bile duct

Choledolithiasis. CP?

C/P: Gallstone pancreatitis. Hepatitis. Obstructive jaundice. Painful. Positive Murphy’s sign. Fever. Leukocytosis.

Choledolithiasis. diagnosis?

RUQ US: obstruction. If negative --> MRCP.

Choledolithiasis. treatment?

Treatment: NPO. IVF fluids. IV Abx if complicated; sepsis. Urgent ERCP: sphincterotomy & elective cholecystectomy. Or urgent cholecystectomy.

Choledolithiasis. followup?

Follow up: ball-valve effect: stone goes up and down the duct; might show improvement but stone is still there so ERCP is required.

Acute cholangitis. etiology?

Ascending infection due to billiary obstruction

Acute cholangitis. CP?

fever, jaundice, RUQ pain (Charcot triad) +/- hypotension, AMS (Reynolds pentad)

Acute cholangitis. labs?

Leukocytosis with a left shift. Direct hyperbilirubinemia. Elevated ALP. Anion gap metabolic acidosis from lactic acidosis.

Acute cholangitis. what is Charcot triad?

fever, jaundice, RUQ pain (Charcot triad)

Acute cholangitis. what is Reynolds pentad?

fever, jaundice, RUQ pain (Charcot triad) +/- hypotension, AMS (Reynolds pentad)

Acute cholangitis. diganosis? labs

Acute cholangitis. US/CT findings?

biliary dilation on US or CT

Acute cholangitis. treatment?

abs coverage of enteric bacteria biliary drainage by ERCP within 24-48h buvo abs pamineti: Ciprofloxacin plus metronidazole. Ampicillin/gentamicin plus metronidazole. dar buvo papildomai prierasas: Therapeutic and diagnostic: emergent ERCP. Other options: percutaneous transhepatic cholangiography and open surgical decompression. Urgent cholecystectomy.

porcelain. definition?

Calcium-laden gallbladder wall with bluish color and brittle consistency. Associated with chronic cholecystitis.

porcelain. CP?

Asymptomatic. RUQ pain. Firm and nontender RUQ mass in PE.

porcelain. diagnosis? xray and CT

X-ray shows a rim like calcification in the area of the gallbladder. CT scan reveals a calcified rim in the gallbladder wall with central bile-filled dark area.

porcelain. treatment?

cholecystectomy

porcelain. Increased risk for gallbladder adenocarcinoma.

Cholangiocarcinoma. definition?

Malignancy of the bile duct epithelium.

Cholangiocarcinoma. risk factors?

Fibropolycystic liver disease. PSC.

Cholangiocarcinoma. CP?

Abdominal pain. Weight loss. Hyperbilirubinemia. Cholestatic liver enzyme pattern. Hepatomegaly and palpable RUQ mass.

Cholangiocarcinoma. diagnosis? labs

Elevated CEA. Elevated Ca19-9. Normal AFP.

Cholangiocarcinoma. diagnosis instrumental?

Abdominal imaging: intrahepatic or CBD dilation and biliary mass. EUS or ERCP required for diagnosis.

bile acid diarrhea. pathophysiology?

Unresorbed bile acids spill into the colon, resulting in mucosal irritation -> bile acid enters terminal ileum too rapidly and overwhelms resorptive capacity (eg post cholecystectomy) -> ileal disease impairs bile absorption (eg Crohn disease, abdominal radiation damage)

bile acid diarrhea. clinical? 3

Secretory diarrhea (eg fasting diarrhea, nocturnal episodes) Bloating, abdominal cramps Unremarkable serum and stool studies

bile acid diarrhea. treatment?

bile acid-binding resins (eg cholestyramine, colestipol)
