Transjugular intrahepatic portosystemic shunt(TIPS) placement is a standard procedure for the treatment of portal hypertension complications. When this conventional approach is not feasible, alternative procedures for systemic diversion of portal blood have been proposed. A one-step interventional approach, combining minilaparotomy-assisted transmesenteric(MAT) antegrade portal recanalization and TIPS, is described in an adolescent with recurrent esophageal varice bleeding and portal cavernoma(PC). A 16-yearold girl was admitted to our Unit because of repeated bleeding episodes over a short period of time due to esophageal varices in the context of a PC. A portal vein recanalization through an ileocolic vein isolation with the MAT approach followed by TIPS during the same session was performed. In the case of failed portal recanalization, this approach, would also be useful for varice endovascular embolization. Postoperative recovery was uneventful. Treatment consisting of propanolol, enoxaparin and a proton pump inhibitor was prescribed after the procedure. One month post-op, contrast enhanced computed tomography confirmed the patency of the portal and intrahepatic stent grafts. No residual peritoneal fluid was detected nor opacification of the large varices. Endoscopy showed good improvement of the varices. Doppler ultrasound confirmed the accelerated flow in the portal stent and hepatopetal flow inside the intrahepatic portal branches. Three months post-op, TIPS maintained its hourglass shape despite a slight expansion. Portal hypertension and life threatening conditions related to PC would benefit from one-step portal recanalization. MAT-TIPS is feasible and safe for the treatment of PC even in children. This minimally invasive procedure avoids or delays surgical treatment or re-transplantation when necessary in pediatric patients.

In CH group, ICAM-1 levels were significantly related to inflammatory activity (P= 0.041) and ALT values (r= 0.77;P＜0.05).

A 68-year-old Caucasian man with hepatitis C virus- related cirrhosis was admitted to our Unit in February 2010 for a diagnostic evaluation of three centimetric hypoechoic focal liver lesions detected by regular sur- veillance ultrasound. The subsequent computer tomog- raphy(CT) led to a diagnosis of unifocal hepatocellular carcinoma(HCC) in Ⅵ hepatic segment, defined the other two nodules in the Ⅵ and Ⅶ segment as sus- pected metastases, and showed a luminal narrowing with marked segmental circumferential thickening of the hepatic flexure of the colon. Colonoscopy detected an ulcerated, bleeding and stricturing lesion at the hepatic flexure, which was subsequently defined as ad- enocarcinoma with a moderate degree of differentiation at histological examination. Finally, ultrasound-guided liver biopsy of the three focal liver lesions confirmed the diagnosis of HCC for the nodule in the Ⅵ segment, and characterized the other two lesions as metastases from colorectal cancer. The patient underwent laparo- tomic right hemicolectomy with removal of thirty-nine regional lymph nodes(three of them tested positive for metastasis at histological examination), and simulta- neous laparotomic radio-frequency ablation of both nodule of HCC and metastases. The option of adju- vant chemotherapy was excluded because of the post- surgical onset of ascites. Abdomen CT and positron emission tomography/CT scans performed after 1, 6 and 12 mo highlighted a complete response to treat- ments without any radiotracer accumulation. After 18 mo, the patient died due to progressive liver failure. Our experience emphasizes the potential coexistence of two different neoplasms in a cirrhotic liver and the complexity in the proper diagnosis and management of the two tumours.

AIM： To accurately differentiate the adenomatous from the non-adenomatous polyps by colonoscopy. METHODS： All lesions detected by colonoscopy were first diagnosed using the conventional view followed by chromoendoscopy with magnification. The diagnosis at each step was recorded consecutively. All polyps were completely removed endoscopically for histological evaluation. The accuracy rate of each type of endoscopic diagnosis was evaluated, using histological findings as gold standard. RESULTS： A total of 240 lesions were identified, of which 158 （65.8%） were non-neoplastic and 82 （34.2%） were adenomatous. The overall diagnostic accuracy of conventional view, and chromoendoscopy with magnification was 76.3% （183/240） and 95.4% （229/240）, respectively （P〈 0.001） CONCLUSION： The combination of colonoscopy and magnified chromoendoscopy is the most reliable nonbiopsy method for distinguishing the non-neoplastic from the neoplastic lesions.

AIM： To report the endoscopic treatment of large hyperplastic polyps of the esophagus and esophagogastric junction （EGJ） associated with Barrett＇s esophagus （BE） with low-grade dysplasia （LGD）, by endoscopic rnucosal resection （EMR）. METHODS： Cap fitted EMR （EMR-C） was performed in 3 patients with hyperplastic-inflammatory polyps （HIPs） and BE. RESULTS： The polyps were successfully removed in the 3 patients. In two patients, with short segment BE （SSBE）（≤ 3 cm）, the metaplastic tissue was completely excised. A 2 cm circumferential EMR was performed in one patient with a polyp involving the whole EGJ. A simultaneous EMR-C of a BE-associated polypoid dysplastic lesion measuring 1 cm × 10 cm, was also carried out. In the two patients, histologic assessment detected LGD in BE. No complications occurred. Complete neosquamous reepithelialization occurred in the two patients with SSBE. An esophageal recurrence occurred in the remaining one and was successfully retreated by EMR. CONCLUSION： EMR-C appears to be a safe and effective method for treating benign esophageal mucosal lesions, allowing also the complete removal of SSBE.

AIM： To investigate the prevalence of the clinical pa- rameters of insulin resistance and diabetes in patients affected by chronic hepatitis C （CHC） or chronic hepa- titis B （CHB）. METHODS： We retrospectively evaluated 852 consec- utive patients （726 CHC and 126 CriB） who had under- gone liver biopsy. We recorded age, sex, ALT, type 2 diabetes and/or metabolic syndrome （MS）, body mass index （BMI）, and apparent disease duration （ADD）. RESULTS： Age, ADD, BMI, prevalence of MS and diabetes in patients with mild/moderate liver fibrosis were significantly higher in CHC. However, the degree of steatosis and liver fibrosis evaluated in liver biop- sies did not differ between CHC and CHB patients. At multivariate analysis, age, sex, BMI, ALT and diabetes were independent risk factors for liver fibrosis in CHC, whereas only age was related to liver fibrosis in CHB. We also evaluated the association between significant steatosis （〉 30%） and age, sex, BMI, diabetes, MS and liver fibrosis. Diabetes, BMI and liver fibrosis were associated with steatosis 〉 30% in CHC, whereas only age and BMI were related to steatosis in CriB. CONCLUSION： These data may indicate that hepatitis C virus infection is a risk factor for insulin resistance.
