Post-cholecystectomy syndrome and magnesium deficiency.

Background And Objective: In 20%-30% of cholecystectomised patients a biliary syndrome (called Post-Cholecystectomy Syndrome: PCES) reappears after some weeks or months. Its etiology, in certain cases, is an anatomic one: (choledochal lithiasis or stricture, obstructive papillitis, pancreatic duct stenosis), but there are many cases in which all organic causes are excluded.

Methods: The aim of this study was to analyze the correlation between these functional disturbances and magnesium (Mg) deficiency (MD).

Post-cholecystectomy syndrome and magnesium deficit.

The serum level of magnesium and calcium was systematically measured in patients with gallstones before and after cholecystectomy. It was found that 60 percent of the operated patients suffered of different digestive syndromes in association with magnesium deficiency, while 40 percent of patients had the same complaints in association of magnesium and calcium deficiency. When magnesium and/or magnesium plus calcium was supplemented these syndromes could be decreased significantly.

Comparative study of two methods for hepatitis B antigen (HBAg) detection: double sequential counterimmunoelectrophoresis (DCIEP) and Ausria II-125I radioimmunoassay.

Double sequential counterimmunoelectrophoresis (DCIEP) (an improved method that we have developed) and Ausria II-125I (an indirect solid-phase radioimmunoassay) were compared for HBAg detection in chronic liver diseases. 26.8% of the patients were positive using DCIEP and 41.
