The most certain symptomatic manifestation of gallstones is episodic upper abdominal pain. Characteristically, this pain is severe and located in the epigastrium and/or the right upper quadrant. The onset is relatively abrupt and often awakens the patient from sleep. The pain is steady in intensity, may radiate to the upper back, be associated with nausea and lasts for hours to up to a day. Dyspeptic symptoms of indigestion, belching, bloating, abdominal discomfort, heartburn and specific food intolerance are common in persons with gallstones, but are probably unrelated to the stones themselves and frequently persist after surgery. Many, if not most, persons with gallstones have no history of pain attacks. Persons discovered to have gallstones in the absence of typical symptoms appear to have an annual incidence of biliary pain of 2-5% during the initial years of follow-up, with perhaps a declining rate thereafter. Gallstone-related complications occur at a rate of less than 1% annually. Those whose stones are symptomatic at discovery have a more severe course, with approximately 6-10% suffering recurrent symptoms each year and 2% biliary complications. The far higher rates of symptom development reported in a few studies raise the possibility that these incidence estimates may be too low. The best predictors of future biliary pain are a history of pain at the time of diagnosis, female gender and possibly obesity. The risk of acute cholecystitis appears to be greater in those with large solitary stones, that of biliary pancreatitis in those with multiple small stones, and that of gallbladder cancer in those with large stones of any number. Drugs that inhibit the synthesis of prostaglandins may now be the treatment of choice in patients with gallstones who are suffering acute pain attacks. Persistent dyspeptic symptoms occur frequently following cholecystectomy. A prolonged history of such symptoms prior to surgery and evidence of significant psychological distress appear to be the best predictors of unsatisfactory outcome.

A case-control study of gallbladder cancer was conducted with 90 Chilean cases registered at one hospital in Santiago city, Chile from January, 1992 to August, 1994. Controls were selected among outpatients of the hospital who received abdominal echography. Each case was assigned 2 age- and sex-matched controls; either with or without gallstone(s). Study subjects were all directly interviewed by well-trained medical students. The present study focused on 74 female pairs and the following findings were obtained: 1) Odds Ratio(OR)s were significantly high for education years less than or equal to 6, body mass index greater than or equal to 24.0, constipation, and consumption of egg, fried meals, green and red chili. Chili pepper consumption of both types in cases showed significantly elevated risks with higher frequency. 2) While high ORs were observed, biliary symptoms such as dyspepsia and past history of cholelithiasis were strongly involved with present gallstone(s) and may not be independent factors for gallbladder cancer. 3) Significantly low ORs were seen for past history of intestinal parasitosis and surgical operation, hormone therapy, all industrial workers and workers in clothes & textile industry. However results may be influenced by more years of education or recall bias. 4) When a conditional logistic model was applied and controls with gallstone(s) were taken as reference, those with the habit of constipation showed a significantly high risk of 2.10 (95% CI: 1.01-4.38), and the consumers of red chili with a frequency > or = 1 time/day had elevated risks of 2.16 (1.27-3.66) vs those < 1 time/day and 4.66 (1.63-13.40) vs non-consumers, respectively. From the above results, the occurrence of gallbladder cancer in Chilean females may be related to constipation and chili pepper consumption, based on the presence of gallstone(s). Further investigations are needed to elucidate whether these are actual risk factors or whether only a false association was detected.
