Surgery is superior to endotherapy for long-term pain reduction in patients with painful obstructive chronic pancreatitis. Better selection of patients for endotherapy may be helpful in order to maximize results. Due to its low degree of invasiveness, however, endotherapy can be offered as a first-line treatment, with surgery being performed in case of failure and/or recurrence.

E. coli Nissle seems to be effective in the restoration of normal colonic colonization and can probably lower endotoxemia in cirrhotic patients.

Pancreatic cancer has the worst prognosis among all cancers. Cancer screening of body fluids may improve the survival time prognosis of patients, who are often diagnosed too late at an incurable stage. Several studies report the dysregulation of lipid metabolism in tumor cells, suggesting that changes in the blood lipidome may accompany tumor growth. Here we show that the comprehensive mass spectrometric determination of a wide range of serum lipids reveals statistically significant differences between pancreatic cancer patients and healthy controls, as visualized by multivariate data analysis. Three phases of biomarker discovery research (discovery, qualification, and verification) are applied for 830 samples in total, which shows the dysregulation of some very long chain sphingomyelins, ceramides, and (lyso)phosphatidylcholines. The sensitivity and specificity to diagnose pancreatic cancer are over 90%, which outperforms CA 19-9, especially at an early stage, and is comparable to established diagnostic imaging methods. Furthermore, selected lipid species indicate a potential as prognostic biomarkers.

There have been only a few studies dealing with the incidence of chronic pancreatitis published. Over the last 80 years, original studies describing the incidence of chronic pancreatitis were undertaken, including studies in Scandinavia, Switzerland, Hungary and Poland. Incidence varied geographically, from 1.6 new cases per year among 100,000 inhabitants in Switzerland to 23 new cases among 100,000 inhabitants in Finland. The aetiology of 70% of all cases was alcoholic pancreatitis. The incidence of chronic pancreatitis in the Czech Republic is 7.9 per 100,000 inhabitants per year, similar to that of Denmark and Germany, but higher than that of Poland or Switzerland. In our study, the main aetiological factor was alcohol (65.4% of all cases, with consumption of alcohol of > 75.0 g/day).

Gastric adenocarcinoma and proximal polyposis of the stomach (GAPPS) is a rare variant of familial adenomatous polyposis. It is an autosomal-dominant cancer-predisposition syndrome with massive polyposis of the stomach and a significant risk of gastric adenocarcinoma. Li et al., 2016, described point mutations in the Ying Yang 1 binding site of the APC gene 1B promoter associated with GAPPS syndrome. The first GAPPS syndrome in a Czech family was described in 2016. At Masaryk Memorial Cancer Institute, GAPPS syndrome was dia gnosed in eight families using Sanger sequencing. In all families, one mutation in promoter 1B of APC gene NM_001127511: c.-191T>C was detected. This mutation was not found in any patient with multiple colon polyposis without a detected classic mutation in the APC gene. In total, 24 carriers of this mutation in promoter 1B of the APC gene were detected. Out of those 24 carriers, 20 had massive gastric polyposis with more than 100 fundic glandular polyps dia gnosed between the age of 22 and 65, 5 had already died of adenocarcinoma of the stomach (at the ages of 29, 40, 59, 60 and 64, respectively) and another woman was treated at the age of 29. Two female carriers do not yet have polyposis of the stomach at the ages of 31 and 65, respectively; one female carrier has incipient polyposis at the age of 58. A male carrier does not have any clinical symptoms, gastroscopy was not indicated because of his age. Prophylactic total gastrectomy with D2 lymphadenectomy has already been performed 6 times at Masaryk Memorial Cancer Institute, in 5 cases without adenocarcinoma at the ages of 27, 34, 44, 51 and 66, respectively; in one female carrier adenocarcinoma of the stomach was detected in a histology specimen. Two prophylactic gastrectomies with D1 lymphadenectomy were performed at University Hospital Brno at the ages of 42 and 50, respectively. In the Czech Republic point mutation c.-191T>C (rs879253783) in the 1B promoter of the APC gene is a frequent cause of gastric polyposis with a high risk of gastric adenocarcinoma, even at a young age. Positively tested individuals are recommended to high-risk oncology clinic. A necessary part of the discus sion with the patient is information about a preventive gastrectomy.

Pancreatic carcinoma is a condition with late diagnosis and one for which there is no effective screening method. One possible diagnostic approach of so-called early adenocarcinoma is the identification and systematic examination of individuals at risk for this condition. Between 1992 and 2005 we systematically observed 223 individuals diagnosed with chronic pancreatitis. In this 14-year period we performed classical biochemical tests, endoscopic ultrasound, CT scans and ERCP. We also asked about the number of cigarettes smoked per year and classified individuals consuming regularly more than 80 g of alcohol per day for 5 years for men and 50 g of alcohol per day for 5 years for women as having the alcoholic form of chronic pancreatitis. The remaining patients were classified according to the TIGARO classification. Alcohol-related etiology was detected in 73.1% of patients, 21.5% had the chronic obstructive form and only 5.4% were classified as idiopathic pancreatitis. Pancreatic carcinoma was detected in 13 patients with chronic pancreatitis (5.8%), 3 patients were diagnosed with gastric carcinoma and 1 with esophageal carcinoma. Pancreatic malignancy developed mainly in patients with the alcoholic form of pancreatitis (4.5%). In the 14-year period 11 subjects died, out of which 8 cases were related to pancreatic carcinoma. Pancreatic and extrapancreatic cancer localized in the gastrointestinal tract are serious complications of chronic nonhereditary pancreatitis. Systematic observation of patients with chronic pancreatitis must be performed with the aim of early diagnosis of pancreatic malignancies (but also including other types).

This method is more demanding than standard endoscopic retrograde cholangiopancreatography due to altered postsurgical anatomy. However, it is effective, safe, and widens the possibilities of resolving biliary pathology.

Autoimmune pancreatitis is a form of chronic pancreatitis of presumed autoimmune aetiology. The disease is characterised with clinical, serological, histomorphological and imaging features. Autoimmune pancreatitis is recognised as a T-cell-mediated specific disease with lymphoplasmatic infiltration of pancreatic tissue and pancreatic parenchyma fibrosis. Serum immunoglobulin IgG or IgG4 and antibodies (rheumatoid factor, lactoferrin antibodies, carbonic anhydrase II, etc) are usually increased. But the lack of specific biochemical markers is a major drawback in the diagnosis of autoimmune pancreatitis. The Japan Pancreas Society proposed diagnostic criteria for autoimmune pancreatitis as the presence antibodies, pancreas enlargement and pancreatic duct narrowing, lymphoplasmatic infiltration, response to corticosteroid therapy, and association with other autoimmune diseases such as autoimmune hepatitis, sclerosing cholangitis, primary biliary cirrhosis, sialoadenitis, inflammatory bowel disease and Sjögren syndrome. New criteria (HISORt Criteria) incorporate imaging changes, organ involvement, specific elevation of IgG4 subclass and histopathological markers. Autoimmune pancreatitis could be associated with diabetes mellitus and exocrine pancreatic dysfunction. Clinically, autoimmune pancreatitis is a disease with mild symptoms; severe attacks of abdominal pain are not typical. Typically, pancreatic calcifications and pseudocyst are absent; on the other hand jaundice and/or pancreatic mass are frequent signs, and both make differential diagnosis with pancreatic cancer difficult. From a practical point of view, in an elderly male presenting with obstructive jaundice and pancreatic mass, autoimmune pancreatitis is one of the differential diagnoses to avoid unnecessary surgical therapy.
