The epidemiological patterns for pancreatic and biliary cancers reveal more differences than similarities. Pancreatic carcinoma is common in western countries, although 2 Polynesian groups (New Zealand Maoris and native Hawaiians) have the highest rates internationally. In the United States the disease is rising in frequency, predominating in males and in blacks. The rates are elevated in urban areas, but geographic analysis uncovered no clustering of contiguous counties except in southern Louisiana. The origin of pancreatic cancer is obsure, but a twofold increased risk has been documented for cigarette smokers and diabetic patients. Alcohol, occupational agents, and dietary fat have been suspected, but not proven to be risk factors. Except for the rare hereditary form of pancreatitis, there are few clues to genetic predisposition. In contrast, the reported incidence of biliary tract cancer is highest in Latin American populations and American Indians. The tumor predominates in females around the world, except for Chinese and Japanese who show a male excess. In the United States the rates are higher in whites than blacks, and clusters of high-risk counties have been found in the north central region, the southwest, and Appalachia. The distribution of biliary tumors parallels that of cholesterol gallstones, the major risk factor for biliary cancer. Insights into biliary carcinogenesis depend upon clarification of lithogenic influences, such as pregnancy, obesity, and hyperlipoproteinemia, exogenous estrogens, familial tendencies, and ethnic-geographic factors that may reflect dietary habits. Noncalculous risk factors for biliary cancer include ulcerative colitis, clonorchiasis, Gardner's syndrome, and probably certain industrial exposures. Within the biliary tract, tumors of the gallbladder and bile duct show epidemiological distinctions. In contrast to gallbladder cancer, bile duct neoplasms predominate in males; they are less often associated with stones and more often with other risk factors. In some respects, bile duct and pancreatic tumors are alike. The male predominance of both tumors, an association between cholecystectomy and pancreatic cancer, and other considerations have prompted the notion that the same biliary carcinogens may affect the bile duct, ampulla of Vater, or, by reflux, the pancreatic duct. Various epidemiological and interdisciplinary approaches are needed to further clarify the origins of biliary tract and pancreatic cancers, but nutritional studies hold special promise in laying the groundwork for prevention of these tumors.

Cytologic brushings of ductal lesions noted at ERCP are a reliable method of diagnosing malignancy. However, prior studies have involved only small numbers of patients. This study presents the results of attempted brushings in 69 patients. A satisfactory specimen was obtained in 62 patients (90%). The overall sensitivity was 44% with 100% specificity. Common bile duct brushings had a higher sensitivity rate than did pancreatic brushings. Similarly, biliary tract cancer was more likely to be diagnosed than was pancreatic cancer by brushing. Markedly atypical cells were identified in 36% of patients with a false negative cytology result. These findings were not seen in patients with benign disease. Two patients developed mild pancreatitis and one developed cholangitis. It is unclear what role the act of brushing had on causing these complications.

In order to evaluate the usefulness of serum DU-PAN-2, we determined this antigen in 384 patients with various malignancies and in 215 patients with benign diseases using a sandwich enzyme immunoassay system (Kyowa Medex Co.). Elevated DU-PAN-2 levels (greater than 400 U/ml) were observed in 55% of hepatocellular cancers, 50% of pancreatic cancers, and 43% of biliary tract cancers. On the other hand, most false-positive cases with benign diseases were observed in patients with liver injury, especially in the acute phase of acute hepatitis, chronic active hepatitis, and liver cirrhosis. However, in only a few cases with other benign diseases including pancreatitis, increased levels were found. Moreover, among the pancreatic cancer or biliary tract cancer patients studied, DU-PAN-2 was positive in 7 of the 19 CA 19-9-negative (less than 37 U/ml) patients and 32 of the 68 CEA-negative (less than 5 ng/ml) patients. These results indicate that the assay of DU-PAN-2 by EIA may have diagnostic usefulness in digestive cancer, especially pancreatic cancer or biliary tract cancer.

When diagnosing autoimmune pancreatitis (AIP), it is most important to differentiate it from neoplastic lesions such as pancreatic or biliary cancers. The revised diagnostic criteria are based on the minimum consensus of AIP in order to avoid misdiagnosing pancreas or biliary cancer as far as possible, but not for screening AIP. Therefore, it is recommended that facile therapeutic diagnosis by steroidal administration should be avoided. These criteria contain three approaches: pancreatic imaging, laboratory data, and histopathology. (i) Pancreatic image examinations show the narrowing of the main pancreatic duct and enlargement of the pancreas, which are characteristic of the disease. (ii) Laboratory data show the presence of autoantibodies or elevated levels of serum gammaglobulin, IgG, or IgG4. (iii) Histopathologial examinations of the pancreas show fibrosis and pronounced infiltration of cells, mainly lymphocytes and plasmacytes, which is called lymphoplasmacytic sclerosing cholangitis (LPSP). For a diagnosis of AIP, criterion (i) must be present, together with criterion (ii) and/or (iii). However, it is necessary to exclude malignant diseases such as pancreatic or biliary cancers.

Autoimmune pancreatitis (AIP) is a particular type of pancreatitis of presumed autoimmune etiology. Currently, AIP should be diagnosed based on combination of clinical, serological, morphological, and histopathological features. When diagnosing AIP, it is most important to differentiate it from pancreatic cancer. Diagnostic criteria for AIP, proposed by the Japan Pancreas Society in 2002 first in the world, were revised in 2006. The criteria are based on the minimum consensus of AIP and aim to avoid misdiagnosing pancreatic cancer as far as possible, but not for screening AIP. The criteria consist of the following radiological, serological, and histopathological items: (1) radiological imaging showing narrowing of the main pancreatic duct and enlargement of the pancreas, which are characteristic of the disease; (2) laboratory data showing abnormally elevated levels of serum gamma-globulin, IgG or IgG4, or the presence of autoantibodies; (3) histopathological examination of the pancreas demonstrating marked fibrosis and prominent infiltration of lymphocytes and plasma cells, which is called lymphoplasmacytic sclerosing pancreatitis (LPSP). For a diagnosis of AIP, criterion 1 must be present, together with criterion 2 and/or criterion 3. However, it is necessary to exclude malignant diseases such as pancreatic or biliary cancer.

Autoimmune pancreatitis (AIP) is a disease which is considered to develop on the background of autoimmune mechanism. It is characterized by unique findings in imagings, appearance of various autoantibodies and elevation of IgG and IgG4 in the blood, and pathologically by lymphoplasmacytic sclerosing pancreatitis (LPSP). It associates various extrapancreatic lesions that have pathological findings similar to the pancreas. Oral prednisolone is a very effective medicine and symptoms and clinical findings disappear soon after the start of steroid therapy. Focal type of AIP is sometimes very difficult to be differentiated from pancreato-biliary cancer that raises dispute over the use of steroids for the differential diagnosis.

Autoimmune pancreatitis (ALP) represents a distinct form of chronic pancreatitis initially described in Japan but now reported worldwide. AIP often presents with obstructive jaundice/pancreatic mass as well as pancreatic exocrine and endocrine insufficiency. Histologically, it is characterised by a lymphoplasmacytic infiltrate with fibrosis. The disease responds readily to steroids in 70-80% of cases. Given the absence of unified diagnostic criteria, the diagnosis of AIP proves difficult. In particular, distinguishing ALP from pancreatic or biliary cancer remains a challenging task. In order to avoid unnecessary resections for an otherwise benign and easily treatable condition, it is urgent to refine diagnostic criteria and to reach an international consensus.

Carbohydrate antigen 19-9 is most valuable as a serum marker for pancreatic and biliary cancer, but increased concentrations occur in several other gastrointestinal malignancies. A carbohydrate antigen 19-9 value of >1,000 U/ml usually indicates a digestive cancer and has been reported to have a specificity greater than 99% for pancreatic cancer; nevertheless, false-positive results owing to benign diseases such as pancreatitis or liver cirrhosis have been noted. We present a patient with cholelithiasis and choledocholithiasis with acute cholangitis who had very high serum levels of carbohydrate antigen 19-9 (9586 IU/ml). The rapid decrease in carbohydrate antigen 19-9 after successful treatment was as interesting as the pretreatment high serum level of carbohydrate antigen 19-9.

Gallstone disease is more common in the elderly. In this short review, we summarize guideline-based recommendations for the diagnosis and treatment of biliary diseases in elderly patients. Warning episodes of biliary colic represent a general indication for cholecystectomy to avoid stone-related complications. Elderly patients with mild and moderate acute cholecystitis should undergo urgent cholecystectomy. After endoscopic retrograde cholangiography and stone extraction as well as mild acute biliary pancreatitis, cholecystectomy should be performed during the same hospital admission. Since the elevated risk of gallstone carriers to develop biliary cancer increases with age, cholecystectomy also protects against cancer.

There is no comprehensive report on the burden of gastrointestinal (GI) and liver diseases in India. In this study, we estimated the age-standardized prevalence, mortality, and disability adjusted life years (DALY) rates of GI and liver diseases in India from 1990 to 2016 using data from the Global Burden of Disease (GBD) Study, which systematically reviews literature and reports for international disease burden trends. Despite a decrease in the overall burden from GI infectious disorders since 1990, they still accounted for the majority of DALYs in 2016. Among noncommunicable disorders (NCDs), there were increases in the prevalence and mortality rates for pancreatitis, liver cancer, paralytic ileus and intestinal obstruction, gallbladder and biliary tract cancer, vascular intestinal disorders, colorectal cancer, and inflammatory bowel disease. Prevalence and mortality rates decreased for peptic ulcer disease, hernias, appendicitis, and stomach and esophageal cancer. For gastritis and duodenitis, cirrhosis and other chronic liver diseases, and gallbladder and biliary tract diseases, there was an increase in prevalence but a decrease in mortality while the opposite was true for pancreatic cancer (decreased prevalence, increased mortality). Indian gastroenterologists and hepatologists must continue to attend to the large majority of patients with infectious diseases while also managing the increasing number of GI and liver diseases, noncommunicable nonmalignant and malignant.
