Intrahepatic Stones (intrahepatic + stone)
Selected AbstractsLifestyle risk factors for intrahepatic stone: Findings from a case,control study in an endemic area, TaiwanJOURNAL OF GASTROENTEROLOGY AND HEPATOLOGY, Issue 7pt1 2008Masato Momiyama Abstract Background and Aim:, To examine associations between lifestyle risk factors and intrahepatic stone (IHS), we conducted a case,control study in Taiwan, which has the highest incidence of IHS in the world. Methods:, Study subjects were 151 patients newly diagnosed with IHS at Chang Gung Memorial Hospital between January 1999 and December 2001. Two control subjects per case were selected randomly from patients who underwent minor surgery at the same hospital and from family members or neighbors of the hospital staff. Controls were matched to each case by age and gender. Information on lifestyle factors was collected using a self-administered questionnaire. Strength of associations was assessed using odds ratios derived from conditional logistic models. Results:, Female patients were significantly shorter than female controls. Compared to subjects with two or fewer children, odds ratios for those with six or more children were 20.4 in men (95% confidence interval, 1.89,221) and 2.82 (0.97,8.22) in women. Increasing level of education lowered the risk of intrahepatic stone (trend P = 0.004 for men and < 0.0001 for women). Women who had consumed ground-surface water for a long period had a somewhat increased risk (trend P = 0.05). Conclusion:, Lower socioeconomic status and poor hygiene may be involved in the development of intrahepatic stones. [source] Surgical management of hepatolithiasisHPB, Issue 3 2009Sujit Vijay Sakpal Abstract Background:, Globalization and intercontinental migration have not just changed the socioeconomic status of regions, but have also altered disease dynamics across the globe. Hepatolithiasis, although still rare, is becoming increasingly evident in the West because of immigration from the Asia-Pacific region, where the disease prevails in endemic proportions. Such rare but emerging diseases pose a therapeutic challenge to doctors. Methods:, Here, we briefly introduce the topic of hepatolithiasis and describe features of intrahepatic stones, the aetiology of hepatolithiasis and the symptoms and sequelae of the condition. We then provide a comprehensive review of the various management modalities currently in use to treat hepatolithiasis. Conclusions:, In our opinion, and as is evident from the literature, surgery remains the definitive treatment for hepatolithiasis. However, non-surgical procedures such as cholangiography, although limited in their therapeutic capabilities, play a vital role in diagnosis and preoperative evaluation.

[source] Biliary access loops for intrahepatic stones: results of jejunoduodenal anastomosisANZ JOURNAL OF SURGERY, Issue 5 2003Hariharan Ramesh Background: Patients with intrahepatic calculi require multiple interventions following successful surgical stone clearance for recurrent stones and cholangitis. The present paper describes the results of a technique of in-continuity side-to-side jejunoduodenal anastomosis (JDA) that provides endoscopic access to the hepaticojejunostomy and intrahepatic ducts. This operation is compared to other techniques in a critical appraisal of various biliary access procedures described for long-term management of intrahepatic calculi. Methods: A retrospective analysis of clinical data of 13 patients who underwent biliary drainage procedures with access loops for intrahepatic calculi during the period March 1990 to December 2000 was performed. The postoperative course of patients and the feasibility of postoperative endoscopic access to the hepaticojejunostomy and intrahepatic ductal system in treatment of recurrent cholangitis were assessed. Nine patients underwent JDA, two underwent permanent-access hepaticojejunostomy (PAH) and two others underwent an interposition hepaticojejunoduodenostomy (IHJ). Results: The analysis revealed no major procedure-related complications or mortality. Endoscopic access (using forward-viewing gastroscope) was possible in 100% of cases following JDA, and with difficulty in both cases after PAH. Endoscopic access in the two patients with IHJ failed because of technical reasons. Recurrent cholangitis was seen in seven patients (54%) , two out of two patients in the PAH group, one out of two in the IHJ group and four out of nine in the JDA group. This required 12 endotherapy sessions (mean: 1.5 procedures per patient). Conclusion: In-continuity side-to-side JDA allows easy access of conventional gastroduodenoscopes to the biliary tree for removal of recurrent/residual intrahepatic stones. The technique has advantages over other access loop procedures in the long term management of recurrent intrahepatic stones. [source] Percutaneous transhepatic choledochoscopic removal of intrahepatic stonesBRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 11 2003M.-T. Cheung Background: Treatment of hepatolithiasis is complex and difficult. With the advent of biliary endoscopy and radiological intervention, percutaneous choledochoscopic removal of intrahepatic stones has become a well established procedure. Methods: Seventy-nine patients with intrahepatic stones that were removed by percutaneous transhepatic choledochoscopy (PTCS) between 1993 and 2001 were studied retrospectively. The results of the procedure and the long-term outcome of these patients were analysed. Results: The success rate of choledochoscopic removal of intrahepatic stones was 76·8 per cent. Complications occurred in 17 patients (21·5 per cent). Removal of stones predominantly on the right side was difficult using this method. Cholangitis occurred in about one third of patients within 3,5 years after PTCS. For patients with a stricture, cholangitis recurred gradually over the years of follow-up. Conclusion: Intrahepatic stricture was the major determinant for the recurrence of stones or symptoms. Hepatic resection should be offered to these patients if the disease is localized in one liver segment or lobe. In other cases, percutaneous choledochoscopy and stricture dilatation is a useful solution, and may reduce further damage to the liver. Copyright © 2003 British Journal of Surgery Society Ltd.
