[Diagnostic strategy in diseases of the small intestine].

For the most frequent and important indications for radiologic examination of the small bowel (passage disorder, blood of unknown origin, inflammatory processes, malabsorption) a diagnostic strategy was established. From the contrast investigations the imaging of the small bowel with a tube, enteroclysma, is preferred. The significance of plain films and sonography is also pointed out. Computed tomography and angiography are rarely indicated. The recommendation of enteroclysma is substantiated by the evaluation of our own series of investigations.

[Frequency and significance of inflammatory pancreatic duct changes in patients with upper abdominal pain of unknown origin].

In 104 patients with longstanding abdominal pain of unknown origin endoscopic pancreatography was carried through after a thorough noninvasive exploration (Secretin-CCK-test included). Pancreatography revealed in 18% slight but distinct-pathological changes at the pancreatic duct system compatible with chronic pancreatitis. As the frequency of the pathological pancreatographic findings showed no correlation with duration of pain history but a significant correlation with age it is suggested that the duct changes encountered represent rather age-dependent irrelevant fibrosis of the pancreas tan clinically relevant chronic pancreatitis. Slight pathological duct changes are by themselves no proof of chronic pancreatitis because there is no possibility to discriminate between chronic pancreatitis and age-dependent fibrosis on the ground of pancreatography. ERP therefore is of little or no value in patients with otherwise insubstantial suspicion of chronic pancreatitis.

[A discrepancy between endoscopic retrograde pancreatography (ERP) and secretin-pancreozymin test (SPT). Attempt of an evaluation (author's transl)].

A discrepancy between the ERP and SPT was found in 16 patients (15,4%) out of 104 examinations. The results of these examinations were compared with the clinical diagnosis. A cause of false positive results of ERP could be operations on pancreas, of SPT the advancing years of the patients. Neither ERP nor SPT has a better diagnostic significance in chronic pancreatitis.

[Exocrine pancreatic function and endoscopic retrograde pancreatography. A comparative evaluation (author's transl)].

The authors have performed successively endoscopic retrograde pancreatography (ERP) and secretin-pancreozymin test (SPT) 104 times. A good correlation between ERP und SPT was demonstrated in 84.6%: 50% of patients with pathologic pancreatogram showed also an abnormal pancreatic function test while 36 (34.6%) out of 104 examinations demonstrated both normlal ERP und SPT. A discrepancy between both procedures was found only in 15.4%: pathologic ERP and normal SPT (9.6%) and reversal (5.8%). In conclusions, ERP and pancreatic function tests appear complementary to each other in the evaluation of pancreatic disorders.

[The contribution of ERCP to the diagnosis of chronic pancreatitis].

A survey is given of the present state of the ERCP in the diagnostics of the chronic pancreatitis. The ERCP is not suited for the proof of early changes in the chronic pancreatitis; it does not allow an exclusion diagnosis. The value of the ERCP in the chronic pancreatitis consists in the fact to render the indication to operation by the proof changes which should be operated on, or to precise it, respectively, and to prevent unnecessary test laparotomies. For this reason the ERCP is indicated above all in the ascertained chronically relapsing pancreatitis and in the persistence of symptoms after an acute inflammatory attack. The most comprehensive information about the morphologic state of the pancreas is got by the combination of the ERCP with methods which reflect the size and the external form of the organ and give evidence concerning the structural changes (sonography, computer tomography).
