An 80-year-old Japanese man with liver cirrhosis was suspected of having lipomatous pseudohypertrophy of the pancreas on the basis of results of ultrasonography and a computed tomography scan. He eventually died of hepatic failure. He had no obesity, diabetes mellitus or pancreatic symptoms during his entire clinical course. Autopsy results confirmed lipomatous pseudohypertrophy of the pancreas, cholecystolithiasis, and postnecrotic liver cirrhosis associated with submassive hepatic necrosis was suspected. Although the pathogenesis of lipomatous pseudohypertrophy of the pancreas is not clear, the findings in the present case provide further evidence to support the hypothesis that advanced hepatic lesions cause this lesion.

Tamoxifen is being used successfully in breast cancer patients as adjuvant hormonal therapy. The aim of this retrospective cohort study is to evaluate the impact of tamoxifen on gallstone formation in postmenopausal breast cancer patients. A total of 3165 patients who were treated for invasive breast cancer between 1990 and 1997 were reviewed. The data were collected from four university hospitals in a population-based registry. Among these patients, 2462 were excluded from the study owing to improper follow-up and other reasons. Premenopausal patients were also excluded. Of the 703 patients included in the study, 457 had received adjuvant therapy including tamoxifen, and the other 246 had not. Gallstone formation was assessed by annual abdominal ultrasonography. The mean follow-up period was 4.6 years (range 1-7 years). There were no significant differences between the groups of breast cancer patients treated with or without tamoxifen regarding the age of the patients at the time of breast cancer diagnosis, the age at menopause, the duration between the onset of menopause and the time the breast cancer was diagnosed, the presence of diabetes, and the body mass index. At the end of 5 years the incidence of gallstone formation in tamoxifen-treated patients was 37.4%, whereas it was 2.0% in patients who did not receive tamoxifen ( p < 0.0001). The incidences of gallstones being detected in 171 tamoxifen-treated patients were 0.4%, 3.7%, 24.4%, 33.1%, and 37.4% cumulatively during the first, second, third, fourth, and fifth years, respectively. Hence adjuvant tamoxifen therapy leads to gallstone formation in postmenopausal breast cancer patients and is most apparent after 3 years of treatment.

We report a case of severe metabolic acidosis associated with acute renal failure and septicaemia following treatment with maximal therapeutic doses of metformin and diclofenac. On the second day of intensive care the patient deteriorated with respiratory insufficiency and abdominal pain during continuous renal replacement therapy. A laparoscopy revealed a perforated cholecystitis with abscess formation. The patient regained renal function and recovered. Intake of diclofenac 5 days before this episode could have been the main cause of renal insufficiency and metabolic acidosis in this patient and could also have delayed surgical treatment by masking early clinical signs of perforated cholecystitis. The renal failure may also have caused metformin and lactate to accumulate, contributing to the mixed pattern of metabolic acidosis. This case report describes a mixed organic and non-organic metabolic acidosis associated with acute renal failure, presumably resulting from a combination of drugs and diseases often found in the elderly - metformin for diabetes mellitus and a non-steroidal anti-inflammatory drug for cholecystolithiasis. Acid-base balance and electrolyte changes were rapidly normalized by continuous renal replacement therapy.

Gallstone disease remains one of the most common medical problems leading to surgical intervention. Every year, approximately 500,000 cholecystectomies are performed in the US. Cholelithiasis affects approximately 10% of the adult population in the United States. It has been well demonstrated that the presence of gallstones increases with age. An estimated 20% of adults over 40 years of age and 30% of those over age 70 have biliary calculi. During the reproductive years, the female-to-male ratio is about 4:1, with the sex discrepancy narrowing in the older population to near equality. The risk factors predisposing to gallstone formation include obesity, diabetes mellitus, estrogen and pregnancy, hemolytic diseases, and cirrhosis. A study of the natural history of cholelithiasis demonstrates that approximately 35% of patients initially diagnosed with having, but not treated for, gallstones later developed complications or recurrent symptoms leading to cholecystectomy. During the last two decades, the general principles of gallstone management have not notably changed. However, methods of treatment have been dramatically altered. Today, laparoscopic cholecystectomy, laparoscopic common bile duct exploration, and endoscopic retrograde management of common bile duct (CBD) stones play important roles in the treatment of gallstones. These technological advances in the management of biliary tract disease are not infrequently accomplished by a multidisciplinary team of physicians, including surgeons trained in laparoscopic techniques, interventional gastroenterologists, and interventional radiologists. With the evolution of laparoscopic cholecystectomy, there has been a global reeducation and retraining program of surgeons. However, the treatment of choice for gallstones remains cholecystectomy. In recognition of the revolutionary advances in the treatment of cholelithiasis, it is the purpose of this collective review to describe recent information on the following topics: types of gallstones, asymptomatic gallstones, symptomatic gallstones, chronic cholecystitis, acute cholecystitis, and other complications of gallstones. Gross and compositional analysis of gallstones allows them to be classified as cholesterol, mixed, and pigment gallstones. When asymptomatic gallstones are detected during the evaluation of a patient, a prophylactic cholecystectomy is normally not indicated because of several factors. Only about 30% of patients with asymptomatic cholelithiasis will warrant surgery during their lifetime, suggesting that cholelithiasis can be a relatively benign condition in some people. However, there are certain factors that predict a more serious course in patients with asymptomatic gallstones and warrant a prophylactic cholecystectomy when they are present. These factors include patients with large (>2.5 cm) gallstones, patients with congenital hemolytic anemia or nonfunctioning gallbladders, or during bariatric surgery or colectomy. Epigastric and right upper quadrant pain occurring 30-60 minutes after meals is frequently associated with gallstone disease. The diagnosis of chronic cholecystitis is made by the presence of biliary colic with evidence of gallstones on an imaging study. Ultrasonography is the diagnostic test of choice, being 90-95% sensitive. The surgical literature suggests that 3-10% of patients undergoing cholecystectomy will have CBD stones. Intraoperative laparoscopic ultrasonography has recently replaced cholangiography as the method of choice for detecting CBD stones. Ultrasonography and radionuclide cholescintigraphy (HIDA scan) are useful in establishing a diagnosis of acute cholecystitis. Laparoscopic cholecystectomy should also be used in the treatment of acute cholecystitis. Laparoscopic cholecystectomy is more likely to be successful when performed within 3 days of the onset of symptoms. It is important to remember that gallstones can lead to a variety of other complications including choledocholithiasis, gallstone ileus, and acute gallstone pancreatitis.

Recently, the incidence of intrahepatic cholangiocarcinoma (ICC) has been increasing in a number of developed (Western) countries. However, risk factors in these low-risk populations are poorly understood. In this nationwide population based case-control study in Denmark, we examined the relationship between selected medical conditions and subsequent ICC risk to provide additional clues to etiopathogenesis. All histologically confirmed ICC cases diagnosed in Denmark between 1978 and 1991 were identified from the Danish cancer registry. Population controls were selected from the central population registry and were matched 4:1 to cases on sex and year of birth. Cases and controls were linked to the Danish hospital discharge registry to obtain information on prior hospital diagnoses. Odds ratios (OR) and 95% confidence intervals (95% CI) were derived using conditional logistic regression. A total of 764 ICC cases and 3,056 population controls were included in the study. Chronic liver diseases were significantly related to ICC: alcoholic liver disease (OR = 19.22, 95% CI = 5.55-66.54), unspecified cirrhosis (OR = 75.9, 95% CI 10.2-565.7). Bile duct diseases were also associated with risk: cholangitis (OR = 6.3, 95% CI = 2.3-17.5), choledocholithiasis (OR = 23.97, 95% CI = 2.9-198.9), cholecystolithiasis (OR = 4.0, 95% CI = 2.0-7.99), though gallbladder removal did not change risk (OR = 1.6, 95% CI = 0.65-3.7). Among other conditions, chronic inflammatory bowel disease (OR = 4.7, 95% CI = 1.65-13.9) was significantly associated with ICC. Diabetes was associated with risk in the year prior to diagnosis of ICC (OR = 3.02, 95% CI = 1.05-8.69). Obesity was unrelated to risk. These results confirm that prior bile duct diseases increase risk of ICC and suggest that alcoholic liver disease and diabetes may also increase risk.

It remains unclear as to whether insulin resistance alone or in the presence of wellknown risk factors, such as diabetes or obesity, is associated with gallstones in men. The aim of this study was to determine whether insulin resistance is associated independently with gallstone disease in non-diabetic men, regardless of obesity. Study subjects were 19,503 Korean men, aged 30-69 yr, with fasting blood glucose level <126 mg/dL and without a documented history of diabetes. Gallbladder status was assessed via abdominal ultrasonography after overnight fast. Body mass index and waist circumference were measured. Insulin resistance was estimated by the Homeostasis Model Assessment of insulin resistance (HOMA-IR). The prevalence of obesity, abdominal obesity, and metabolic syndrome in the subjects with gallstones were higher than in those without. The prevalence of elevated HOMA (>75 percentile) in subjects with gallstones was significantly higher than in those without, and this association remained even after the obesity stratification was applied. In multiple logistic regression analyses, only age and HOMA proved to be independent predictors of gallstones. Insulin resistance was positively associated with gallstones in non-diabetic Korean men, and this occurred regardless of obesity. Gallstones appear to be a marker for insulin resistance, even in non-diabetic, nonobese men.

The purpose of this study was to examine a previous increase in male gallstone disease and to consider the burden of gallstones in a necropsy study with matched controls over a decade. Gallstone prevalence in 5,050 males fell from 20.2% to 19.1% (P=0.022) and in 4,125 females fell from 30.4% to 29.0% (P=0.03). Female gallstone subjects had a higher BMI than controls 24.5 vs. 23.3 (P<0.01), but males did not. Gallstones were twice as common in diabetics, but not with coronary heart disease (CHD). A third of elderly patients of both sexes had gallstones, but cholecystectomy was more common in females, 17:10%. Gallstone-related mortality was 0.7%. The prevalence of gallstones fell slightly. The association between gallstones and diabetes was confirmed, but not for CHD, and for BMI this was confined to females. Gallstones are very common in the elderly, but most are unoperated and seldom cause death.

We evaluated the prevalence and the risk factors for gallstone disease in patients with chronic hepatitis C infection. We investigated 453 consecutively admitted patients with chronic infection with hepatitis C virus (HCV) (cirrhosis excluded) and 879 patients without liver disease (October 2006-April 2007). Gallstone disease was diagnosed if gallstones were present at ultrasonography or if there had been a previous cholecystectomy. Variables evaluated were age, gender, gallstone heredity, body mass index, waist circumference, parity, serum lipids, fatty liver, arterial hypertension, diabetes mellitus and metabolic syndrome (International Diabetes Federation criteria). Informed consent was obtained from all patients. We found that 88 of 453 (19%) patients with chronic HCV hepatitis (age 50.1 +/- 11.7 years) and 153 of 879 (17%) controls (age 60.6 +/- 12.6 years) had gallstone disease (GD). Abdominal obesity (OR = 2.108, 95% CI 1.287-3.452) and steatosis (OR = 3.699, 95% CI 2.277-6.008) were risk factors for GD in HCV patients. Gallstone heredity, dyslipidaemia, type 2 diabetes mellitus and metabolic syndrome increased the risk for GD in controls vs HCV patients. Our study shows that even HCV patients with chronic hepatitis but not cirrhosis have an increased prevalence of gallstones. Compared with controls, gallstones are present in HCV patients at a younger age and are associated with central obesity and liver steatosis, but not with gallstone heredity, dyslipidaemia, diabetes mellitus or metabolic syndrome. Although we could not establish a temporal relationship, the association between HCV infection and gall stone disease is real and appears to be causally linked, at least in predisposed individuals (obese and with liver steatosis).

Background. The aim of this study is to evaluate the incidence of gallstone after gastrectomy, risk factors for gallstone formation, and the surgical outcome of cholecystectomy after gastrectomy. Methods. A total of 2480 gastric cancer patients who underwent curative resection at two institutions between January 1997 and December 2012 were retrospectively reviewed. The patients' age, gender, diabetes mellitus, type of gastrectomy, extent of node dissection, and type of reconstruction were evaluated. Results. Gallstone formation occurred in 128 of 2480 (5.2%) patients who had undergone gastrectomy for gastric cancer. The incidence of gallstones was significantly higher after total compared with subtotal gastrectomy. Roux-en-Y reconstruction and lymph node dissection in the hepatoduodenal ligament were associated with a significantly higher incidence. In multivariate analysis, diabetes mellitus and reconstruction method were identified as significant risk factors for gallstone development. The proportion of silent stone was higher in the laparoscopic cholecystectomy (LC) group than in the open cholecystectomy (OC) group. Operation time and hospital stay were shorter in the LC group than in the OC group. Conclusions. Diabetes mellitus and Roux-en-Y reconstruction are risk factors for gallstones after gastrectomy. Only a few postoperative complications after subsequent cholecystectomy occurred, even when using a laparoscopic approach.

The aim of this study was to evaluate the frequency of gallbladder stone in functional dyspepsia (FD) by abdominal ultrasonography and to determine the factors associated with this frequency in Guilan province. A total of 195 subjects who referred to outpatient clinic of Razi Hospital, a tertiary referral center (Guilan, Iran) to evaluate FD were included in this study. They were interviewed by using a questionnaire and underwent ultrasonography. Among the 195 subjects were 18.5% male and 81.5% female. The overall frequency of Gallstones (GS) was 19% (37/195) with 17% males and 83% female. In patients with dyspepsia, the presence of fatty liver evidenced by ultrasonography was 67% (131/195). From 131 patients with fatty liver disease 24 (18.3%) have been reported GS. The most frequent symptom in all participants as well as patients with GS and patients with fatty liver was abdominal pain (69.7%, 81% and 66%, respectively) followed by excess flatus. Risk factor associated with increased odds ratios (ORs) for the development of gall stones was diabetes mellitus (OR = 2.63). It also showed that gallbladder wall thickening was more common in patients with GS (OR = 36.63). GS disease was not significantly related to the age, gender, fatty liver, renal stone, history of hypertension (HTN) and hyperlipidemia (HLP), alcohol consumption and smoking status. Patients with FD especially if they have diabetes should be referred for upper abdominal ultrasonography for screening and early detection of GS disease.
