Effect of pancreatic biliary reflux AS A cofactor in cholecystitis

الملخص EN

This study assessed the effect of pancreatico-biliary reflux (PBR) as co-factor in the process of chronic cholecystitis by measurement of the levels of active pancreatic enzyme amylase in gallbladder bile and serum of patients undergoing cholecystectomy.

Pancreatic Amylase levels in bile from the gallbladder and serum were measured during surgery in 68 patients with chronic calcular cholecystitis subjected to elective open or laparoscopic cholecystectomy in the National Hepatology and Tropical Medicine Research Institution and Theodore Bilharz Research Institute.

Bile amylase was detected in 64 patients (94.1 %) indicating pancreatico-biliary reflux.

Biliary amylase level ranged from 20-50 IU / L in 42patients (61.76 %), below 20 IU / l in 14 patients (20.59 %), over 50 IU / L in 8 patients (11.76 %) and undetectable in two patients.

According to gallbladder bile amylase, the incidence of Occult PBR in patients operated upon for chronic calcular cholecystitis was 94.1 %.

The reason should be clarified by further research and wider scale study.

Routinely investigating biliary amylase in every patient having cholecystitis can be a method for early detection of precancerous lesions.
