Is serum amylase measured four hours after endoscopic sphincterotomy a reliable predictor of postprocedure pancreatitis?
Serum amylase assessment 4 h after ES minimizes the likelihood of underestimating the risk of postprocedure pancreatitis. It is therefore a reliable, cost-effective follow-up, particularly in outpatients.
Correction for chromosome-17 is the method of choice for clinical practice; Her-2>6, but not Her-2>4, could be used as an alternative.
