METHODS:From December 1987 to December 2007, 276 patients underwent hepatic resection for hepa-tolithiasis in Changhua Christian Hospital.Sixty-five patients were excluded due to incomplete medical records and the remaining 211 patients constituted our study population base.Ten patients were diag-nosed with C-CCA based on the preoperative biopsy or postoperative pathology.During the follow-up period, 12 patients developed S-CCA.The diagnosis of S-CCA was made by image-guided biopsy or by pathology if surgical intervention was carried out.Patient charts were reviewed to collect clinical information.Parameters such as CCA incidence,interval from operation to CCA diagnosis,interval from CCA diagnosis to disease-related death,follow-up time,and mortality rate were calculated for both the C-CCA and S-CCA groups.The outcomes of the C-CCA and S-CCA groups were math-ematically compared and analysed. RESULTS:Our study demonstrates the clinical implications and the survival outcomes of C-CCA and S-CCA. Among the patients with unilateral hepatolithiasis,the incidence rates of C-CCA and S-CCA were fairly similar (4.8%vs 4.5%,respectively,P=0.906).However,for the patients with bilateral hepatolithiasis,the incidence rate of S-CCA(12.2%)was higher than that of C-CCA (4.7%),although the sample size was limited and the difference between two groups was not statistically sig-nificant(P=0.211).The average follow-up time was 56 mo for the C-CCA group and 71 mo for the S-CCA group.Regard to the average time intervals from operation to CCA diagnosis,S-CCA was diagnosed after 67 mo from the initial hepatectomy.The average time intervals from the diagnoses of CCA to disease-related death was 41 mo for the C-CCA group and 4 mo for the S-CCA group,this difference approached statistical sig-nificance(P=0.075).Regarding the rates of overall and disease-related mortality,the C-CCA group had signifi-ca展开更多

HPA is caused by invasion and migration of nematode,Ascaris lumbricoides,in to the biliary tract and pancreatic duct. Patients present with biliary colic,cholangitis,cholecystitis,hepatic abscesses and acute pancreatitis. Ascarides traverse the ducts repeatedly,get trapped and die,leading to formation of hepatolithiasis. HPA is ubiquitous in endemic regions and in Kashmir,one such region,HPA is the etiological factor for 36.7%,23%,14.5% and 12.5% of all biliary diseases,acute pancreatitis,liver abscesses and biliary lithiasis respectively. Ultrasonography is an excellent diagnostic tool in visualizing worms in gut lumen and ductal system. The rational treatment for HPA is to give appropriate treatment for clinical syndromes along with effective anthelmintic therapy. Endotherapy in HPA is indicated if patients continue to have symptoms on medical therapy or when worms do not move out of ductal lumen by 3 wk or die within the ducts. The worms can be removed from the ductal system in most of the patients and such patients get regression of symptoms of hepatobiliary and pancreatic disease.展开更多
