IntroductionThe high recurrence rate of hepatolithiasis, together with the high operative risk of hepatectomy performed for stones in cer− tain locations has until now been a difficult problem. In this re− port we describe a new treatment method we have devised to prevent postoperative recurrence of hepatolithiasis. Based on our previous animal experiments, this method of chemical bile duct embolization effectively results in chemical hepatectomy [1,2]. Case reportA 52−year−old woman was admitted to our hospital with intrahe− patic and extrahepatic lithiasis and acute suppurative cholangi− tis. Immediately after admission, she underwent emergency cho− ledocholithotomy and T−tube drainage, and was scheduled for a left lateral lobectomy later on. However, because of her poor clin− ical condition, she refused to undergo the planned hepatectomy. With her consent, therefore, we performed chemical bile duct embolization to prevent recurrence of the stones. After the cho− ledochoscopic cholelithotomy, the biliary balloon catheter was placed at the opening of stenotic bile duct. Selective cholangiog− raphy was then performed, which showed multiple biliary calcu− li complicated by a biliary stricture in the inferior branch of left lateral bile duct (Figure 1). After washing with normal saline, the targeted hepatic duct was injected with a volume of absolute ethanol equal to that of the contrast medium. Fifteen minutes la− ter, the absolute ethanol was aspirated and then an equal amount of cyanoacrylate (Jingya Co., Beijing, China) was injected quickly, under pressure. Six seconds later, the balloon catheter was pulled out.During the first 2 days after the chemical bile duct embolization, she had a low fever, her white blood cell count was 8.7The surgical treatment of hepatolithiasis is associated with a high postoperative recurrence rate. We present here the case of a 52−year−old woman who underwent emergency surgical cho− ledocholithotomy and T−tube drainage for acute cholangitis and common bile duct lithiasis. She refused subsequent treatment with hemihepatectomy for localized left inferior duct dilatation with stones and so we treated her by injecting a combination of absolute ethanol and cyanoacrylate into the diseased biliary duct lumen as a biliary embolizing reagent. Two months later, her T−tube cholangiography revealed that the targeted biliary ducts were completely ocluded; 15 months later, computed to− mography showed that the inferior segment of the left lateral lobe had almost completely atrophied, thus demonstrating suc− cessful chemical resection of this diseased hepatic lobe. Further systematic evaluation of this experimental technique is warranted to assess efficacy and complications. Case Report 845Downloaded by: University of British Columbia. Copyrighted material.

We study the ferromagnetic criticality of the pyrochlore magnet Lu 2 V 2 O 7 at the ferromagnetic transition T C % 70 K from the isotherms of magnetization MðHÞ via an iteration process and the Kouvel-Fisher method. The critical exponents associated with the transition are determined: b = 0.32(1), c = 1.41(1), and d ¼ 5:38. The validity of these critical exponents is further verified by scaling all the MðHÞ data in the vicinity of T C onto two universal curves in the plot of M=jej b versus H=jej bþc , where e ¼ T=T C À 1. The obtained b and c values show asymmetric behaviors on the T < T C and the T > T C sides, and are consistent with the predicted values of 3D Ising and cubic universality classes, respectively. This makes Lu 2 V 2 O 7 a rare example in which the critical behaviors associated with a ferromagnetic transition belong to different universality classes. We describe the observed criticality from the Ginzburg-Landau theory with the quartic cubic anisotropy that microscopically originates from the anti-symmetric Dzyaloshinskii-Moriya interaction as revealed by recent magnon thermal Hall effect and theoretical investigations.
