[Therapeutic effect of sulfobenzyl-penicillin (SB-PC) on the concentration of SB-PC in human bile (author's transl)].

Sulfobenzyl-penicillin (SB-PC) is currently being investigated for use in man. The purpose of this study was to evaluate effect of SB-PC on Salmonella typhosa and biliary excretion of SB-PC in disease of the biliary tract. 1) Clinically, typhoid carriers without cholelithiasis were initiated with 4.0 g/day of SB-PC. Stool and bile became negative for Salmonella typhosa 14 days after initial treatment. 2) In typhoid carriers with cholelithiasis, Salmonella typhosa were not isolated from bile, wall of the gallbladder and surface of gallstone, but were isolated from nuclei of gallstones. The treatment of typhoid carriers with cholelithiasis may belong to a most difficult problem. 3) Biliary excretion of SB-PC in the patient given a single dose of 2.0 g/day im. was markedly dependent on characteristics of the patient, situation of external drainage and volume of bile excretion. High concentration in bile in some patient was 298 mug/ml at 3 hours after administration. 4) In intravenous administration of single dose of 6.0 g. maximum concentration in bile was about 2,000 mug/ml at 2 hours after administration and bactericidal concentration was obtained for resistant bacteria (Pseudomonas, Proteus, etc.) in biliary infection. 5) As side effects, pain and redness were infrequent after im. administration. Toxicity was not experienced in the patients injected intravenously.

Whether or not prophylactic excision of the extrahepatic bile duct is appropriate for patients with pancreaticobiliary maljunction without bile duct dilatation.

BACKGROUND/AIMS: The standard treatment for patients with a pancreaticobiliary maljunction (PBM) without bile duct dilatation remains controversial. METHODOLOGY: We followed up 29 patients with such PBM who mainly underwent a cholecystectomy alone. The ages of the patients ranged from 3 to 76 years (average age 47.3 years) and the ratio of males to females was 8 vs. 21. When the diameter of the common bile duct was less than 10mm, such bile ducts were diagnosed to have no dilatation. The main clinical indications for surgery were cholecystolithiasis in 15 patients, choledocholithiasis in 3, cholecystocholedocholithiasis in 2, gallbladder polyp in 2, adenomyomatosis in 2, cholecystitis in 2, and protein plug in 1. RESULTS: The amylase levels of gallbladder bile in 20 patients ranged from 115 to 460,200 IU/mL (a mean of 191,698 IU/mL). One patient died of gastric cancer 182 months after surgery and two patients died of other diseases 153, 171 months after surgeries, respectively. The remaining 26 patients have all been doing well for 36 months to 326 months after surgery (a median follow-up period, 160.5 months). The 10- and 15-year survival rates were 100% and 89.7%. CONCLUSIONS: In conclusion, a prophylactic resection of the extrahepatic bile duct and biliary diversion could be unnecessary for patients with PBM without bile duct dilatation.
