Hepatolithiasis and intrahepatic cholangiocarcinoma: A review

引用

World Journal of Gastroenterology 2015年第48期21卷 13418-13431页

作者： hyo jung kim Jae Seon kim Moon Kyung Joo Beom Jae Lee Ji Hoon kim Jong Eun Yeon Jong-Jae Park Kwan Soo Byun Young-Tae Bak Department of Internal Medicine Korea University college of MedicineGuro Hospital

Although the incidence of hepatolithiasis is decreasing as the pattern of gallstone disease changes in Asia, the prevalence of hepatolithiasis is persistently high, especially in Far Eastern countries. Hepatolithiasis is an established risk factor for cholangiocarcinoma(CCA), and chronic proliferative inflammation may be involved in biliary carcinogenesis and in inducing the upregulation of cell-proliferating factors. With the use of advanced imaging modalities, there has been much improvement in the management of hepatolithiasis and the diagnosis of hepatolithiasis-associated CCA(HLCCA). However, there are many problems in managing the strictures in hepatolithiasis and differentiating them from infiltrating types of CCA. Surgical resection is recommended in cases of single lobe hepatolithiasis with atrophy, uncontrolled stricture, symptom duration of more than 10 years, and long history of biliaryenteric anastomosis. Even after resection, patients should be followed with caution for development of HL-CCA, because HL-CCA is an independent prognostic factor for survival. It is not yet clear whether hepatic resection can reduce the occurrence of subsequent HL-CCA. Furthermore, there are no consistent findings regarding prediction of subsequent HL-CCA in patients with hepatolithiasis. In the management of hepatolithiasis, important factors are the reduction of recurrence of cholangitis and suspicion of unrecognized HL-CCA.

Application of the Prague C and M criteria for endoscopic description of columnar-lined esophagus in South Korea

作者： jung Wan Choe Young Choon kim Moon Kyung Joo hyo jung kim Beom Jae Lee Ji Hoon kim Jong Eun Yeon Jong-Jae Park Jae Seon kim Kwan Soo Byun Young-Tae Bak Department of Gastroenterology Korea University Guro Hospital

AIM:To ascertain whether the Prague circumferential(C) length and maximal(M) length criteria for grading the extent of Barrett's esophagus can be applied prior to its widespread application in South ***:Two hundred and thirteen consecutive cases with endoscopic columnar-lined esophagus(CLE) were included and classified according to the Prague C and M ***:Of 213 cases with CLE, the distribution of maximum CLE lengths was: 0.5-0.9 cm in 99 cases(46.5%); 1.0-1.4 cm in 63 cases(29.6%); 1.5-1.9 cm in 15 cases(7.0%); 2.0-2.4 cm in 14 cases(6.6%); 2.5-2.9 cm in 1 case(0.5%); and 7.0 cm in 1 case(0.5%). Twenty cases(9.4%) had columnar islands alone. Two hundred and eight cases(97.7%) lacked the circumferential CLE component(C0Mx). Columnar islands were found in 70 cases(32.9%), of which 20 cases(9.4%) had columnar islands ***:In regions where most CLE patients display short or ultrashort tongue-like appearance, more detailed descriptions of CLE's in < 1.0 cm lengths and columnar islands, as well as avoidance of repeating the prefix "C0" need to be considered in parallel with the widespread application of the Prague system in South Korea.

Dear Editor,H∞This letter develops a new framework for the robust stability and performance conditions as well as the relevant controller synthesis with respect to uncertain robot *** often exist model uncertainties between the nominal model and the real robot manipulator and disturbances. Hence, dealing with their effects plays a crucial role in leading to high tracking performances, as discussed in [1]–[5].
