Total biliary protein, mucus glycoproteins, cyclic-AMP, and apolipoproteins in the gallbladder bile of patients with cholesterol stones and stone-free controls.

The concentrations of total protein, mucus glycoprotein, cyclic-AMP, and apolipoproteins A-I, A-II, and B were determined in the gallbladder bile of patients with cholesterol gallbladder stones and in stone-free controls. The total protein content was significantly increased in gallstone patients (2.03 +/- 0.

Diagnostic fine-needle puncture of the gallbladder with US guidance.

From February 1988 to January 1990, 118 fine-needle diagnostic punctures of the gallbladder (DPG) were performed under continuous ultrasound (US) guidance on symptomatic patients with gallstones. The first attempt at gallbladder puncture and aspiration was successful in every patient with use of a 22-gauge needle and continuous US visualization of the needle tip. The aspirated volume varied between 3 and 88 mL (average +/- standard deviation, 25.

[Comparison of ultrasound-controlled fine needle and coarse needle puncture of defined lesions in the abdomen].

Within a 2-year period 677 diagnostic fine needle (DFP) and coarse needle punctures (DGP) were performed in 536 patients. In 34 patients (14 women; 20 men; 54 +/- 17.6 years) the abdominal tumour mass was punctured with the fine needle (22 g) as well as with the coarse (18 g) needle.

[Preventing the recurrence of common bile duct calculi following endoscopic papillotomy with ursodeoxycholic acid].

The effect of ursodeoxycholic acid on recurrence prevention of choledochal calculi after endoscopic sphincterotomy (EPT) was evaluated in 46 patients, whose bile duct stones had been removed endoscopically. 22 patients received 500 mg of ursodeoxycholic acid once a day, 24 patients received placebo. 1 recurrent stone could be detected in the ursodeoxycholic acid treated group 19 months after EPT, whereas 4 recurrent stones occurred in the placebo group about 16 months after EPT.
