BACKGROUND/AIMS: Gallbladder polyps (GBP) are a common clinical finding and may possess malignant potential. We conducted this study to determine whether visceral obesity is a risk factor for GBP. METHODS: We retrospectively reviewed records of subjects who received both ultrasonography and computed tomography with measurements of the areas of visceral adipose tissue and total adipose tissue (TAT) on the same day as health checkups. RESULTS: Ninety-three of 1,615 subjects (5.8%) had GBP and were compared with 186 age- and sex-matched controls. VAT (odds ratio [OR], 2.941; 95% confidence interval [CI], 1.325 to 6.529; p=0.008 for the highest quartile vs the lowest quartile) and TAT (OR, 3.568; 95% CI, 1.625 to 7.833; p=0.002 for the highest quartile vs the lowest quartile) were independent risk factors together with hypertension (OR, 2.512; 95% CI, 1.381 to 4.569; p=0.003), diabetes mellitus (OR, 2.942; 95% CI, 1.061 to 8.158; p=0.038), hepatitis B virus positivity (OR, 3.548; 95% CI, 1.295 to 9.716; p=0.014), and a higher level of total cholesterol (OR, 2.232; 95% CI, 1.043 to 4.778; p=0.039 for <200 mg/dL vs > or =240 mg/dL). Body mass index and waist circumference were not meaningful variables. CONCLUSIONS: Visceral obesity measured by VAT and TAT was associated with GBP irrespective of body mass index or waist circumference.

The goal of this study was to evaluate the association between gallbladder (GB) polyps and metabolic syndrome. A total of 5,685 healthy subjects were included, and 485 of these subjects had GB polyps and 744 had metabolic syndrome. In this study, metabolic syndrome was diagnosed according to standards suggested by the AHA/NHLBI ATP III 2005, and abdominal obesity (> or = 90 cm in men and > or = 85 cm in women for Korean) was diagnosed according to standards set forth by the Korean Society for Study of Obesity. Biphasic logistic regression adjusted for age and gender was used to evaluate the association between metabolic syndrome and GB polyps. Subjects who were male (OR, 1.493; 95% CI, 1.11-2.00) and hepatitis B suface Ag (HBsAg) positive (OR, 1.591; 95% CI, 1.06-2.38) were significantly more likely to have GB polyps. The metabolic syndrome group had a higher risk of GB polyps (OR, 1.315; 95% CI, 1.01-1.69) than the group without metabolic syndrome. In conclusion, subjects who were HBsAg positive and male appear to be associated with the risk of GB polyps. The presence of metabolic syndrome also appears to be associated with the risk of GB polyps in Koreans.

Obesity is an important health problem in the world and related to many critical diseases, such as diabetes, cardiovascular disease, and metabolic syndrome. Obesity leads to fat infiltration of multiple organs and infiltrated adipose tissue produces many cytokines resulting in the dysfunction of organs such as the gallbladder. In the biliary diseases, obesity and overweight have been known as a major risk factor for gallstones. According to current studies, obesity, insulin resistance, hyperinsulinemia, and metabolic syndrome are related to various gallbladder diseases including gallbladder stones, cholecystitis, gallbladder polyps, and gallbladder cancers. We reviewed further literature on the obesity and gallbladder diseases, in aspects of epidemiology, mechanism, pathology and prevention.

Endoscopic retrograde biliary drainage (ERBD) is useful for the palliative decompression of biliary obstruction. However, the complications of ERBD include cholangitis, hemorrhage, acute pancreatitis, obstruction of the stent, and duodenal perforation. Pressure necrosis on the duodenal mucosa by the stent may contribute to perforation. Although duodenal perforation following ERBD is very rare compared to other complications, it can result in a fatal outcome. Recent reports describe nonsurgical treatment for small gastrointestinal perforation with localized peritonitis and suggest that endoclipping may be appropriate in the management of a well selected group of patients with iatrogenic perforation. We describe a case of duodenal perforation secondary to ERBD that was successfully treated with approximating using endoclip and detachable snare.

Radiofrequency ablation (RFA) is performed as an alternative to surgical resection for primary or secondary liver malignancies. Although RFA can be performed safely in most patients, early and late complications related to mechanical or thermal damage occur in 8-9.5% cases. Hemocholecyst, which refers to hemorrhage of the gallbladder, has been reported with primary gallbladder disease or as a secondary event associated with hemobilia. Hemobilia, defined as hemorrhage in the biliary tract and most commonly associated with accidental or iatrogenic trauma, is a rare complication of RFA. Here we report a case of hemocholecyst associated with hemobilia after RFA for hepatocellular carcinoma that was successfully managed by laparoscopic cholecystectomy.

Gallbladder perforation is an almost exclusive complication of cholecystitis, which accompanies severe inflammation of the gallbladder with or without cholelithiasis. Whether it is of a calculous or acalculous origin, gallbladder perforation, as a complication of acute cholecystitis, has common symptoms, signs, laboratory data, radiological findings and treatment modalities. Even though many reports of gallbladder perforation have been published, there are few reports of gallbladder perforation without any clinical and radiological indications. We experienced a case of a 70-year-old woman with acute abdomen, which was found to be peritonitis caused by spontaneous gallbladder perforation that was devoid of clues suggesting this condition. Although rare and unusual, this case shows that this disorder should be considered in elderly patients presenting with peritonitis with an unknown etiology.

Although acute acalculous cholecystitis (AAC) accounts for less than 10% of acute cholecystitis in the adult population, gangrene and perforation are much more frequent compared to the usual cases of acute cholecystitis (calculus cholecystitis). However, spontaneous biliary-enteric fistula is well recognized in AAC, 90% of which are cholecystoduodenal fistula (CDF) though it is an uncommon disorder. The majority of the CDF are caused by cholelithiasis. As patients are usually associated with complicated clinical illness, the diagnosis is often difficult to make and required surgery is often delayed. We have studied a rare complication of acute acalculous cholecystitis which was presented as intermittent upper gastrointestinal bleeding. Ulceration of the superficial branch of the cystic artery has been observed due to acalculous cholecystitis associated with a cholecystoduodenal fistula. We have performed a transfixing ligation of the bleeding vessel, cholecystectomy and simple closure of the CDF. We have finally made a diagnosis of early gallbladder cancer through a frozen section. There was no serious complication after the operation and the patient has achieved an uneventful recovery.

OBJECTIVETo investigate changes in renal function, urine N-acetyl-beta-D-glucosaminidase enzyme (N-AG),liver function, myocardial enzymes, the pathology of renal damage and the mechanism of acute renal failure (ARF) associated with fish gall bladder poisoning.

METHODSEleven patients with acute fish gall bladder poisoning were consecutively admitted to our hospital from September 1997 to October 1999. Renal function, urine N-AG enzyme, liver function, and myocardial enzymes were assayed before and after treatment. One patient consented to a kidney biopsy and the pathology of renal damage was observed under light and electron microscopes.

RESULTSAll patients had multiple organ dysfunction syndrome (MODS) and 11 patients suffered from ARF. Ten patients had liver dysfunction, ten patients had poisonous myocarditis, and 8 patients had gastrointestinal dysfunction. Renal function, urine N-AG enzyme, liver function, and myocardial enzymes were significantly improved after treatment compared with those of before treatment (P < 0.05). Kidney biopsy showed that the main damage site was the proximal renal tubule. All eleven patients recovered and were discharged from the hospital.

CONCLUSIONSIngestion of fish gall bladder leads to kidney damage, as well as liver, heart and gastrointestinal tract injury. The mechanism of acute renal function failure is the serious tubular damage, confirming the location of kidney damage. Necrosis of the proximal tubules plays an important role in the development of ARF. Immediate hemodialysis is the most effective treatment.

Percutaneous liver biopsy is valued in the diagnosis of diffuse or localized liver disease. Serious complications after ultrasonography-guided liver biopsy are rare. We report a case of a 69-year-old man who underwent a percutaneous liver biopsy for the evaluation of his underlying liver disease with subsequent late complication of intraluminal gallbladder hematoma.
