BACKGROUND: Obstructive jaundice is often accompanied by bacterial translocation and subsequent sepsis. The effect of lactulose in preventing that process was evaluated in an experimental model. Obstructive jaundice was induced in 23 rabbits after common bile duct ligation. METHODS: Animals were divided into two groups. Group A of 11 animals-controls and group B of 12 rabbits, which received 2 ml/kg of lactulose p.o. by a nasogastric tube. Blood was sampled daily, before and after operation. Samples were applied for culture and for estimation of endotoxins (LPS), tumor necrosis factor (TNFa), and malondialdehyde (MDA). RESULTS: Mean (+/-SD) survival of animals of group A was 3.08+/-0.19 days compared to 5.36+/-0.41 days of animals of group B. Serum concentrations of LPS and TNFa of each day of treatment remain constant in animals of group A; they were steadily decreased in animals of group B reaching statistical significance on the fourth day. Similar changes were not found for MDA. CONCLUSION: The administration of lactulose may prevent systemic endotoxaemia and the subsequent inflammatory response in an experimental model of obstructive jaundice, so as to extend survival. These results merit further clinical evaluation.

Congenital web of the common bile duct in association with cholelithiasis.

Congenital web formations are extremely rare anomalies of the extrahepatic biliary tree. The age at presentation and the clinical symptomatology of these anomalies depend on the grade of the biliary obstruction. We report a case of a common bile duct septum in association with cholelithiasis in a 30-year-old woman. The diagnosis was made on preoperative magnetic resonance cholangiopancreatography (MRCP) and confirmed with intraoperative cholangiography. Because all known causes of acquired web formation were excluded, a congenital origin of the web was assumed. The patient was treated with a hepaticoduodenostomy above the level of the septum. The embryological aspects of this rare anomaly are described.
