Objective: The aim of this study was to evaluate the main pathologic component of bile obtained by biliary drainage in patients with acute idiopathic pancreatitis and therapeutic implications.
Method: Eighteen patients diagnosed with idiopathic acute pancreatitis underwent biliary drainage. Microscopic evaluation of bile was performed and pathologic components were classified in cholesterol microcrystals, bilirubinate granules, and calcium microspherolites.
Results: Five patients showed no abnormalities. In 11 patients, bilirubinate granules were found, cholesterol microcrystals in two, and Giardia lamblia in two.
Conclusion: Bilirubinate granules are the main pathologic component of bile in patients with acute idiopathic pancreatitis. Cholecystectomy is the preferred therapeutic approach.

Diagnostic Point-of-Care Ultrasound (POCUS) for Abdominal Pain: A Case of Tumefactive Sludge.

Emergency, Hospital de Braga, Braga, PRT.
Article Synopsis
- * Tumefactive sludge is a rare finding in the gallbladder and must be differentiated from conditions like gallbladder cancer and gangrenous cholecystitis.
- * Point-of-care ultrasound (POCUS) is a valuable tool for diagnosing gallbladder issues, as it effectively assesses gallbladder conditions and helped diagnose a case of abdominal pain caused by tumefactive sludge.

Biliary sludge (or very thick bile) is mainly comprised of calcium bilirubinate granules and lesser amounts of cholesterol crystals, and it can produce a layer of low amplitude of echoes in the most dependent part of the gallbladder (GB). In tumefactive biliary sludge, low-amplitude echoes do not form a fluid-fluid level but instead tend to give the appearance of a polypoid mass that is bounded by a smooth margin, round, and lobulated. Differential diagnoses for an echogenic mass in the GB lumen include GB carcinoma, tumefactive sludge, and gangrenous cholecystitis.

Background And Aims: Microlithiasis has been suspected to cause acute pancreatitis and biliary pain. We studied the frequency of microlithiasis and response to treatment in recurrent idiopathic acute pancreatitis (RIAP) and unexplained biliary pain.
Methods: Gallbladder bile was examined microscopically for cholesterol monohydrate crystals (CMC) and calcium bilirubinate granules (CBG) in patients with RAIP (n = 24; mean age 36 years, range 18-56 years; 14 men), unexplained biliary pain (n = 12; mean age 32 years, range 22-55 years; six men), gallstones (n = 22; mean age 40 years, range 30-58 years; 12 men) and patients without clinical or imaging evidence of gallstone disease (n = 12; mean age 32 years, range 14-54 years; six men).

Acalculous biliary pain has been related to gallbladder dysfunction that produces a gallbladder emptying defect-a condition which favours the development of lithiasis. It is therefore probable that microlithiasis is present in patients with gallbladder dysfunction. The aims of this study were to measure gallbladder emptying and investigate bile abnormalities in patients with acalculous biliary pain.

Background: The passage of gallstones (macro- or microlithiasis) is theorized to play a role in inducing sphincter of Oddi dysfunction. This study examined the frequency at which biliary crystals are found in patients with suspected type II and type III sphincter of Oddi dysfunction.
Methods: A total of 85 patients (66 women, 19 men; mean age 38 years) with unexplained abdominal pain of suspected pancreatobiliary origin and no prior episode of pancreatitis underwent ERCP with sphincter of Oddi manometry and bile collection for crystal analysis.
