Chronic pancreatitis (CP) is an inflammatory disorder characterized by inflammation and fibrosis, resulting in a progressive and irreversible destruction of exocrine and endocrine pancreatic tissue. Clinicians should attempt to classify patients into one of the six etiologic groups according to the TIGARO classification system. MRI/MRCP, if possible with secretin enhancement, is considered the imaging modality of choice for the diagnosis of early-stage disease.In CP, pain is the most disabling symptom, with a significant impact on quality of life. Pain should be assessed using the Izbicki score and preferably treated using the "pain ladder" approach. In painful CP, endoscopic therapy (ET) can be considered as early as possible. This procedure can be combined with extracorporeal shock-wave lithotripsy (ESWL) in the presence of large (> 4 mm), obstructive stone(s) in the pancreatic head, and with ductal stenting in the presence of a single main pancreatic duct (MPD) stricture in the pancreatic head with a markedly dilated MPD. Pancreatic stenting should be pursued for at least 12 months in patients with persistent pain relief. On-demand stent exchange should be the preferred strategy. The simultaneous placement of multiple, side-by-side, pancreatic stents can be recommended in patients with MPD strictures persisting after 12 months of single plastic stenting. We recommend surgery in the following cases: a) technical failure of ET ; b) early (6 to 8 weeks) clinical failure ; c) definitive biliary drainage at a later time point; d) pancreatic ductal drainage when repetitive ET is considered unsuitable for young patients; e) resection of an inflammatory pancreatic head when pancreatic cancer cannot be ruled out; f) duodenal obstruction. Duodenopancreatectomy or oncological distal pancreatectomy should be considered for patients with suspected malignancy. Pediatricians should be aware of and systematically search for CP in the differential diagnosis of chronic abdominal pain. As malnutrition is highly prevalent in CP patients, patients at nutritional risk should be identified in order to allow for dietary counseling and nutritional intervention using oral supplements. Patients should follow a healthy balanced diet taken in small meals and snacks, with normal fat content. Enzyme replacement therapy is beneficial to symptomatic patients, but also in cases of subclinical insufficiency. Regular follow-up should be considered in CP patients, primarily to detect subclinical maldigestion and the development of pancreatogenic diabetes. Screening for pancreatic cancer is not recommended in CP patients, except in those with the hereditary form. [less ▲]

Curative resection of primary tumor and metastases is the only way to obtain a prolonged survival. Several additional treatments are under evaluation; some are already routinely proposed, in order to reduce the tumor size and to allow surgery, to reduce the recurrence rate, and to give a better survival in case of unresectable metastases. Even in case of unresectable metastases, resection of the primary tumor should be envisaged, as quality of life with an evolving rectal tumor is very poor. [less ▲]

Stress related ulcers are superficial and extensive gastric mucosal lesions. They occur in almost all critically ill patients but lead to gastrointestinal bleedings in only 5 to 10%. Endoscopy permits definitive diagnostic. Stress related mucosal diseases encount for substantial morbidity and mortality. The preventive therapeutic choice depends on efficacy, side effects as cost and nosocomial pneumonia. Sulcralfate appears to be the best choice because of its lower cost, comparable efficacy (sucralfate versus anti-H2) and its lower risk of inducing nosocomial pneumonia. Patients who greatly benefit from prevention, present respiratory failure with at least 48 hours mechanical ventilation, coagulopathy, sepsis or burns. Global management avoiding hypoxia, hypotension and acidosis, takes an important part in the prevention. [less ▲]

Long-term treatment with omeprazole induces hyperplasia of enterochromaffin-like cells, closely related to hypergastrinemia. We studied whether proglumide, an antagonist of gastrin/CCK receptor, and enprostil, a synthetic prostaglandin E2 derivative, might inhibit this hyperplasia. Six groups of 8 rats were treated for 10 weeks: a) untreated controls; b) omeprazole 10 mumol/kg; c) proglumide 500 mg/kg; d) enprostil 30 micrograms/kg; e) association of omeprazole and proglumide; f) association of omeprazole and enprostil. Serum gastrin levels were measured at different times during treatment. After sacrifice, fundic argyrophil cells were assessed by Grimelius' staining. Serum gastrin levels and argyrophil cell density were not modified in proglumide- and enprostil-treated groups, as compared with controls. Omeprazole increased significantly these two parameters. When given with omeprazole, proglumide decreased significantly serum gastrin levels and argyrophil cell density, as compared to omeprazole alone, while enprostil did not modify significantly these two parameters. These results indicate that proglumide, but not enprostil, can counteract the omeprazole-induced argyrophil cell hyperplasia in rats. [less ▲]

Hypergastrinemia induces argyrophil cell hyperplasia in oxyntic mucosa (FACH) in patients with non-antral atrophic gastritis, with or without pernicious anemia. This proliferation favours the development of carcinoid tumours. In order to determine the most usual appropriate method to document FACH, we have studied 29 consecutive fundic biopsies from 26 patients with fundic chronic gastritis. The study encompassed gastrinemia levels, standard histology permitting the classification of chronic gastritis, demonstration of FACH by Grimelius stain, immunohistochemical studies using NSE, chromogranin A and by electron microscopy. The FACH was classified for each stain as slight, moderate or severe. The study displayed a relationship between the grade of gastritis and the density of argyrophil endocrine cells in oxyntic mucosa assessed by Grimelius stain (p < 0.0001) and chromogranin A (P < 0.01). There was also a relationship between the serum gastrin level and the density of argyrophil endocrine cells detected by these two stains (p < 0.001). A highly significant correlation was observed between Grimelius stain and chromogranin A (p < 0.0001). On the other hand, no significant correlation was noted with either NSE or electron microscopy. We conclude that Grimelius stain and immunohistochemical studies against chromogranin A were the best methods for the demonstration of FACH in atrophic gastritis. One of these two techniques is sufficient in current practice for defining the patients at risk for subsequent surveillance. [less ▲]

It is clear since many years that the liability to develop inflammatory bowel disease is influenced by genetic factors. Recent progresses in the field of genetic markers and genetic models bring the concept of genetic heterogeneity. This new concept leads us to try to classify different forms of inflammatory bowel disease and could have in the future an impact on the prevention, the follow up and the treatment of these diseases.

The enterochromaffin-like (ECL) cells represent the predominating endocrine cell population in the oxyntic mucosa of the stomach. They are under the influence of gastrin. Recently, a histamine production was shown within the secretory granules of ECL cells. ECL cells appear to play a crucial role in the physiology of gastric acid secretion. There are many unknowns concerning the intervention of other trophic factors in addition to gastrin and concerning the receptors located on the cells. ECL cell hyperplasia is a well documented consequence of hypergastrinemia. The latter can result from a gastrinoma or from a reduction of gastric acid secretion related to pernicious anemia or to long-term treatment with antisecretory drugs. [less ▲]
