Diseases presenting with dyspepsia fall into two general categories: organic and functional. Overall, most patients with dyspepsia have no underlying identifiable disease process. The diagnostic yield of organic causes is less in younger patients, and, conversely, serious organic lesions are common in elderly dyspeptic patients. The commonest organic causes of dyspepsia are peptic ulcer disease, gastroesophageal reflux, biliary tract disease, and gastric cancer. Symptoms and physical signs may help to differentiate these organic causes from functional dyspepsia but endoscopic or radiographic/ultrasound studies are usually necessary to ensure the appropriate diagnosis. Less common organic causes of dyspepsia not to be overlooked include drugs, pancreatitis, malabsorption syndromes, metabolic disorders, ischemic heart disease, and collagen vascular disorders.

Two hundred and fifty cases of biliary tract disease were studied as regards case history, physical and laboratory investigations, surgery and follow-up. It was found that females especially multipara were frequently affected; majority of cases were in 3rd to 5th decade of their life, rise in age showing decline in incidence. Majority of cases (82.4%) were vegetarians and had used vegetable fats (oriental diet). Most of the cases (98.8%) belonged to middle and poor class and were lean and thin. Pain in the right upper quadrant of the anterior abdominal wall had been the commonest symptom, in about half the cases it got aggravated by fatty meals. A mass was felt in the right hypochondrium in 29.6% and Murphy's sign was positive in 55.5% of cases. Radio-opaque calculi were present in 8% of cases, in another 10.8% the calculi were demonstrated by oral cholecystography, radiography could detect calculi in 47 (25.4%) cases and its overall diagnostic success rate has been low (56.8%). Ultrasonography proved more valuable tool for diagnosis; bile culture was positive in 8.8% of cases only for Esch coli, proteus, klebsiella, staphylococci or paracolon. Right subcostal incision gave the best results. Chronic cholecystitis with cholelithiasis (74%) was more common than acalculus cholecystitis (26%), incidence of carcinoma was 2.8%, and in 5 out of 7 cases malignancy was associated with cholelithiasis. Early diagnosis and cholecystectomy for gallstones can prevent malignancy. Surgery on the whole proved beneficial and it can be more rewarding if pre-operatively other causes of dyspepsia are either excluded or confirmed. Excluding cases of malignancy, the mortality has been quite low and thus acceptable.

Dyspepsia, defined as chronic or recurrent upper abdominal pain or nausea, is a common occurrence. Dyspepsia without an ulcer (non-ulcer dyspepsia) is diagnosed in patients at least twice as often as peptic ulceration. Diseases that may present with similar symptoms include gastroesophageal reflux, biliary tract disease, chronic pancreatitis, and irritable bowel syndrome. A careful history and physical examination, supplemented by selected tests, usually lead to a correct diagnosis. The pathogenesis of non-ulcer dyspepsia remains unknown. Gastric acid secretion, duodenogastric reflux, psychological factors, environmental exposures, and heredity probably do not play a major role. Some patients may have motility disturbances, but whether these disturbances cause dyspepsia is unknown. Campylobacter pylori infection and associated gastritis are common in non-ulcer dyspepsia, but their etiologic role is controversial, as is the importance of chronic duodenitis. By recognizing the heterogeneity of patients who present with non-ulcer dyspepsia, more rational management may be possible. Although an empiric trial of antacids or H2 blockers has been recommended to treat dyspepsia, most controlled trials show that although these substances reduce severity of symptoms, they are no more effective than placebos in non-ulcer dyspepsia.

Since Helicobacter pylori (Hp) was first isolated in 1983, much work has been carried out on the pathogenic effects of this organism. Hp infection is common in humans and currently is the most important etiologic agent in the development of chronic active gastritis, gastric and duodenal ulcers, carcinoma and Malt-lymphoma of the stomach. Moreover Hp infection has also been associated with various extradigestive diseases. At present, a role of Hp infection in dyspepsia is discussed. Dyspepsia is defined by persistence of pain, burning or discomfort localised to the upper abdomen; some authors include in dyspepsia symptoms such as belching, bloating, alitosis, nausea, postprandial repletion, vomiting and regurgitation. In absence of any underlying pathologies, such as peptic ulcer, gastroesophageal reflux, pancreatitis, biliary tract disease or others, dyspepsia is defined as functional or idiopathic dyspepsia. Functional dyspepsia may be distinct in ulcer, reflux or dysmotility-like dyspepsia and unspecified dyspepsia. Hp infection is common in dyspeptic patients and a role of this bacterium has been postulated mostly in ulcer-like dyspepsia. Mechanisms by when Hp induces dyspeptic symptoms are uncertain; bacterial cytotoxins, phlogosis mediators, activity of chronic gastritis Helicobacter-related and host immune response probably play an important role in pathogenesis of functional dyspepsia. However, dyspepsia is not present only in infected patients; therefore other pathogenic factors may be implicated in expression of dyspeptic symptoms in uninfected subjects, such as gastric dysmotility, modifications of gastric output or altered visceral sensibility, psychological factors, gastroesophageal reflux and irritable bowel.
