Porcelain gallbladder is a rare disorder by deposition of calcium in the wall of gallbladder. The chronic cholecystitis is reported to produce mural calcification and obstruction to the cystic duct by stone. Since porcelain gallbladder is commonly associatedwith gallbladder cancer, cholecystectomy is prerformed to prevent it. We report here a case of a patient with porcelain gallbladder. This case showedthe typical ultrasonogaphic, computer tomogaphic and radiaographic findings of the disease.

Although the incidence of gallbladder cancer is relatively low, Korea is one of the countries with the highest incidences of gallbladder cancer in the world. Gallbladder cancer is also often diagnosed in an advanced state, and has poor prognosis. A gallstone is one of the major risk factors for gallbladder cancer and a majority of epidemiological studies support correlation between cholelithiasis and gallbladder cancer. Clear mechanism, however, regarding how gallstones cause gallbladder cancer is not known. In this article, results of studies about the relationship between gallstone and gallbladder cancer were thoroughly reviewed. Also, it was discussed whether prophylactic cholecystectomy is necessary to prevent gallbladder cancer in asymptomatic gallstone patients without other risk factors such as a gallbladder polyp or porcelain gallbladder.

Carcinoma of the gallbladder is an uncommon but highly malignant tumor with a poor five year survival rate. Early detection is very important for successful treatment because this tumor is very hard to cure in cases where it has advanced beyond the reach of surgical treatment. The purpose of this review was to evaluate risk factors for carcinoma of the gallbladder and determine the best management approach.. Solitary polys, more than one cm are considered to be predisposing factors for gallbladder carcinoma when they are found to be echopenic, sessile, and with a high cell density. Anomalous union of the pacreato-biliary duct(AUPBD) without a choledochal cyst is also considered to increase risk for gallbladder carcinoma. A polyps size of more than one cm and an AUPBD are indications for prophylactic cholecystectomy. The presence of gallstones is a well-established risk factor for the development of gallbladder carcinoma; risk appears to correlate with the stone size and the duration of chronic cholecystitis. Metaplastic changes of the gallbladder epithelium present with chronic cholecystitis and may indicate a premalignant lesion. Abnormal forms of cholecystitis such as xanthogranulomatous or a porcelain gallbladder also have malignant potential; cholecystoenteric fistula as well as bacterial infection of the gallbladder(typhoid, helicobacter species) also has malignant potential. In this review, the risk factors associated with carcinoma of the gallbladder are summarized with special attention to gallstones, polyps, AUPBD, and chronic inflammation.

Acalculous hemorrhagic cholecystitis is a rare complication of acute cholecystitis and is associated with a high mortality rate. We present a case of acalculous hemorrhagic cholecystitis with hematoma in the gallbladder lumen, which was diagnosed using magnetic resonance imaging (MRI). The T1- & T2-weighted MRI revealed gallbladder distension with a hypointense intraluminal hematoma. The excellent tissue contrast provided by MRI is useful for detecting hematomas in the cases of hemorrhagic cholecystitis.

Background/aim : Gallbladder stone is the most common disease of biliary tract. It is lead to acute abdominal pain. The cholecystitis which is caused by in gallbladder stone occurs frequently and the possibility of the gallbladder cancer comes to be high. Our study was designed to determine the prevalence and risk factors gallbladder stone in a population who community. Materials and Methods : We enrolled a total of 826 (male : 297, female : 529) persons who 60 or older in Jeju-do 10 places from 2008 July one months. The height, weight, liver function tests, lipid profile, fasting blood sugar, were all measurement. They had their gallbladder examined with using ultrasonography. Statistical significance was defined as a p-value less than 0.05. Results : Among 826 persons, gallbladder stone was found in 49 persons (5.9%). The male is 6.1% and the female is 5.8%, the male 1.03 times appeared more highly the female. The body mass index above of 23.0 kg/$m^2$ with the gallbladder stone was 69.3% (p<0.047). Conclusion : The gallbladder stone appeared highly according to age increases. The obesity is the risk factor of gallbladder stone. The weight management and diet control is a possibility of reducing a gallbladder stone creation.

Laparoscopic cholecystectorny can be performed safely in most patients with symptomatic cholelithiasis. Preoperative evaluation should assess the potential problems that affect the performance of laparoscopic cholecystectomy. Hepatobiliary scintigraphy or oral cholecystography can assess the gallbladder function and nonvisualization of gallbladder usually indicates acute or severe chronic cholecystitis. The purpose of this study was to evaluate the role of preoperative hepatobiliary scintigraphy or oral cholecystography in predicting the performance of laparoscopic cholecystectorny. The study group consists of 176 patients who underwent both hepatobiliary scintigraphy with Tc-99m DISIDA and oral cholecystography within one month before laparoscopic cholecystectomy. Nonvisualization of gallbladder was defined as persistent nonvisualization of gallbladder until 4 hours on hepatobiliary scintigraphy or 12 hours on oral cholecystography. Among 176 patients, gallbladder was not visualized in 38 patients on hepatobiliary scintigraphy and 41 patients on oral cholecystography. Concordance rate between hepatobiliary scintigraphy and oral cholecystography was 89.2%. The conversion rate to open cholocystectomy was significantly higher in patients with nonvisualization of gallbladder than in patients with gallbladder visualization(15.8% vs 2.9% on hepatobiliary scintigraphy, 12.2% vs 3.7% on oral cholecystography p<0.01 and p<0.05 respectively). The operative complication rate was also significantly higher in patients with nonvisualization of gallbladder (13.2% vs 2.9% on hepatobiliary scintigraphy, 14.6% vs 2.2% on oral cholecystography p<0.01 and p<0.001, respectively). Similarly, operation time was significantly prolonged in patients with nonvisualization of gallbladder ($88.8{\pm}41.9min$ vs $62.5{\pm}23.6min$ on hepatobiliary scintigraphy : p<0.001, $89.4{\pm}41.3$ min vs $61.8{\pm}22.8$ min on oral cholecystography : p<0.001). It is concluded that nonvisualization of gallbladder on hepatobiliary scintigraphy or oral cholecystography is a valuable preoperative clinical risk factor in predicting increased conversion rate to open cholecystectomy, increased operative complication and prolonged operation time.

Background/Aims : Gallbladder(GB) stone is the most common disease in the biliary system, and the incidence is gradually increasing in Korea. This change may include rapidly proceeding urbanization and changing food factor. We performed this study to investigate related GB stones and contraction of GB as dietary factors. Methods : We investigated 129 subjects(mean age : 47 years). GB stone group is 9 subjects(M: 2, F: 7) in Namyangju-si. Control group without GB stone is 18 subjects(M: 6, F: 12) in Wi-do island. For subjects without GB stone, diabetes mellitus decide 4(M: 2, F: 2) and then each after eat flesh and meat of estimated by experimental group ejection fraction rate(%). Results : Ejection fraction rate of GB were different between meat and fishes intake. When ate the meat in experiment for hypothetical verification, when become ejection fraction rate of meal GB 210 minutes, was the highest and when ate fish, the ejection fraction rate of GB was the highest in meal 120 minutes. Conclusions : After meats intaking the bile inside the GB is stagnant long and the GB stone is formed. We studied the results GB motility may important play a role on GB stone formation.

Transgastric endoscopic cholecystectomy was successfully accomplished in a 1-year-old, 15 kg, female, mongrel dog. Single-working channel flexible gastric endoscope was used with the aid of one abdominal laparoscopic port. Gastrotomy was performed using endoscopic needle knife at the ventral antral region. Through the gastric incision endoscope was advanced and retroflexed for the visualization of gallbladder. For the better exposure of surgical field, gentle traction was applied at the fundus of the gallbladder using laparoscopic grasping forceps. Cystic duct and artery was ligated using endoclips. After transecting the duct and artery, gallbladder was dissected using endoscopic coagulating grasping forceps and needle knife. Resected gallbladder was retrieved through the mouth and gastric incision site was sutured using endoclips. There was no evidence of bile leakage or stomach leakage on postoperative day (POD) 3. On POD 16, gastric endoscopy and laparoscopy was performed. Gastric endoscopy revealed complete adhesion of incision site. The content of the peritoneum appeared healthy, with no sign of infection, bile staining, or organ injury. The omentum was adhered over resected gallbladder fossa and the serosal surface of gastrotomy site. This is the first report of NOTES cholecystectomy in the dog and provides new concept of cholecystectomy of the dog.

Purpose Acute cholecystitis is a complication of transarterial chemoembolization (TACE) that occasionally requires surgical intervention. We aimed to analyze the incidence and risk factors of cholecystitis requiring surgical intervention in patients with embolic material uptake on cone beam CT (CBCT) performed immediately after various TACE procedures. Materials and Methods After a retrospective review of 2633 TACE procedures performed over a 6-year period, 120 patients with embolic material retention in the gallbladder wall on CBCT immediately after TACE were selected. We analyzed the incidence of and risk factors for acute cholecystitis. Results The overall incidence of acute cholecystitis requiring surgical intervention was 0.45% (12 of 2633 TACE procedures); however, it was present in 10% (12 of 120) of procedures that showed high-density embolic material retention in the gallbladder wall on CBCT performed immediately after TACE. Acute cholecystitis requiring surgical intervention occurred in eight patients (66.7%) who underwent direct cystic arterial embolization. Surgical intervention was performed 15 days (mean) after TACE. Conclusion Most unintended chemolipiodol deposits in the gallbladder wall resolved without intervention or surgery. However, superselective direct cystic arterial chemoembolization was associated with a high incidence of acute cholecystitis requiring surgery, and patients who undergo this procedure should be closely monitored.
