    Abstract:
    In the present study the time courses of serum lipase, serum amylase and serum elastase 1 after ERCP/ES as indicators for pancreatic damage were prospectively analysed in 46 cases. The elevations of pancreatic enzymes after ERCP/ES scattered in a wide range and elevations occured which were greater than one hundred times the upper limit of normal. A moderate increment was seen as early as 5 minutes after intubation of the papilla. Elevations above the upper limit of normal were still seen at 24 hours after the procedure. The maxima occurred about 6 hours after the procedure. Lipase was the most sensitive among the parameters tested, nearly 50% of the cases with previously normal values revealed elevated lipase after the procedure. For daily clinical routine a single lipase measurement at 2 hours after the beginning of the ERCP/ES provides valuable information for planning further surveillance. Younger age and high calcium levels seem to be risk factors for ERCP/ES-induced pancreatic damage. The time course of serum lipase seems to be a more reliable criterion for ERCP/ES-induced pancreatic damage than the poorly defined complication of post-ERCP pancreatitis . The high incidence of a measurable pancreatic injury after ERCP/ES provides a sensitive tool for the testing of drugs claimed to be protective for the pancreas and for evaluating new ERCP/ES techniques. Measurement of the serum lipase before, 8 and 24 hours after the procedure, and a detailed description of degree and duration of pain, are necessary for such studies.
