The diagnostic yield of ERCP in the investigation of unexplained abdominal pain.
One hundred and forty patients with undiagnosed severe chronic abdominal pain who had not undergone previous biliary surgery were investigated by ERCP. A diagnosis was achieved in 34 patients (24 per cent) including 8 with previously undiagnosed peptic ulceration and 5 with gallstones. Twenty-five patients (18 per cent) had an abnormal pancreatogram, including 1 with pancreatic cancer. The incidence of pancreatogram abnormalities suggestive or diagnostic of pancreatitis was particularly high (60 per cent) in patients with a history of alcohol abuse. ERCP has a valuable role in the investigation of patients with 'obscure' abdominal pain.
