The concept of chronic pancreatitis has been stated in our country much later than acute pancreatitis. This manuscript proposes a synthesis of the etiopathogenic, diagnostic and therapeutic data in chronic pancreatitis based on actual information correlated with the results of our experimental study. The experiment was conducted on 18 animals, in which was performed the intraduodenal ligation of the pancreatic duct apertures and the obstruction of the pancreatic ducts with intraparenchymatous, intraoperative neoprene injections. We investigated the lesions by using intraoperative pancreatic tissue collected after injections. The results encourage us to continue the research and to choose genetically modified animals because are closer to the human one.

The pathogenesis of chronic pancreatitis and pain syndrome had not been fully studied. The aim of the study was to evaluate the interrelation of fibrotic and ischemic changes in the parenchyma of pancreas, and pancreatic duct pressure in the pathogenesis of chronic pancreatitis. In a prospective study, a morphological, the immunohistochemical study of pancreatic preparations was performed, and the indicators of tissue oximetry and pancreatic duct pressure were studied intraoperatively in 40 patients operated for chronic pancreatitis. It was found that with the progression of fibrotic changes in the pancreatic tissue of patients with chronic pancreatitis, there was an increase in TGF-β1 expression (р < 0.001), an increase in the number of pancreatic stellate cells (r = 0.32, р < 0.05), a decrease in glycogen (ischemia marker). The intraoperative direct measurement revealed a high pancreatic duct pressure: 34.2 (26.6; 45.3) mm Hg, a decrease in oxygenation of the pancreatic tissue that correlate with a degree of fibrosis. The pancreatic tissue in chronic pancreatitis has chronic hypoxia associated with fibrosis and increased pancreatic ductal hypertension. So, secondary pancreatic ischemia can be a significant factor in the progression of fibrosis and chronic pain syndrome in chronic pancreatitis.

AbstractPancreaticopleural fistula is a rare complication of chronic pancreatitis caused by disruption of the pancreatic duct and fistulous communication with the pleural cavity. It usually presents with respiratory symptoms from recurrent large volume pleural effusions. Paucity of abdominal symptoms makes it a diagnostic challenge, leading often to delayed diagnosis. Marked elevation of pleural fluid amylase, which is not a commonly performed test, is a sensitive marker in its detection. Imaging with magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography can help delineate the fistula. In this report, we present the clinical features, imaging, and management of a 59-year-old male patient with pancreaticopleural fistula, wherein the diagnosis was suspected only after repeated pleural fluid drainages were performed for re-accumulating pleural effusions and it was eventually successfully treated with pancreatic duct stenting. We review the literature with regards to the incidence, presentation, diagnosis, and management of this rare entity.

The findings from endoscopic retrograde pancreatography (ERP) and secretin-CCK test data were compared in 69 patients: 36 with chronic pancreatitis, 9 with possible chronic pancreatitis, and 24 without chronic pancreatic disease. The ERP findings were also compared with the histologic changes in pancreatic tissue in 18 patients who underwent pancreatic surgery for chronic pancreatitis. ERP films were reviewed according to the criteria proposed by Kasugai et coll. (8) with special attention paid to the side branches. Secretin-CCK test data were interpreted using the discriminant analysis. A good correlation between bicarbonate and chymotrypsin output and ductular changes at ERP was found. The results of ERP and the secretin-CCK test were compatible in 86 per cent of the patients. The relationship between ERP findings and histologic changes was not straightforward. It was concluded that ERP and the secretin-CCK test are complementary in the diagnosis of chronic pancreatitis. ERP does not necessarily represent the histology in chronic pancreatitis.

Discriminating between focal chronic pancreatitis and pancreatic cancer is always a challenge in clinical medicine. Contrast-enhanced endoscopic ultrasound using Doppler techniques can uniquely reveal different vascularisation patterns in pancreatic tissue alterated by chronic inflammatory processes and even allows a discrimination from pancreatic cancer. This paper will describe the basics of contrast-enhanced high mechanical index endoscopic ultrasound (CEHMI EUS) and contrast enhanced low mechanical index endoscopic ultrasound (CELMI EUS) and explain the pathophysiological differences of the vascularisation of chronic pancreatitis and pancreatic carcinoma. Furthermore it will discuss how to use these techniques in daily clinical practice.
