Uniportal thoracoscopy combined with laparoscopy as minimally invasive treatment of esophageal cancer

2018

A 67-year-old man was referred to our attention for management of esophageal adenocarcinoma, localized at the level of the esophagogastric junction and obstructed the 1/3 of the esophageal lumen. Due to the extension of the disease (T3N1M0-Stage IIIA), the patient underwent neo-adjuvant chemo-radiation therapy and he was then scheduled for a minimally invasive surgical procedure including laparoscopic gastroplasty, uniportal thoracoscopic esophageal dissection and intrathoracic end-to-end esophago-gastric anastomosis. No intraoperative and post-operative complications were seen. The patient was discharged in post-operative day 9. Pathological study confirmed the diagnosis of adenocarcinoma …

Non invasive tools for the diagnosis of liver cirrhosis

2014

Liver cirrhosis (LC), the end stage of many forms of chronic hepatitis of different etiologies is a diffuse process characterized by fibrosis and the conversion of normal liver architecture into structurally abnormal nodules surrounded by annular fibrosis. This chronic progressive clinical condition, leads to liver cell failure and portal hypertension, which can favour the onset of hepatocellular carcinoma. Defining the phase of the natural history is crucial for therapeutic choice and prognosis. Liver biopsy is currently considered the best available standard of reference but it has some limits, so alternative tools have been developed to substitute liver biopsy when assessing liver fibros…

Systematic review with meta-analysis: the haemodynamic effects of carvedilol compared with propranolol for portal hypertension in cirrhosis

2013

Summary Background Propranolol is recommended for prophylaxis of variceal bleeding in cirrhosis. Carvedilol is a nonselective beta-blocker with a mild anti-alfa-1-adrenergic activity. Several studies have compared carvedilol and propranolol, yielding inconsistent results. Aim To perform a systematic review and meta-analysis of the randomised clinical trials comparing carvedilol with propranolol for hepatic vein pressure gradient reduction. Methods Studies were searched on the MEDLINE, EMBASE and Cochrane library databases up to November 2013. The weighted mean difference in percent hepatic vein pressure gradient reduction and the relative risk of failure to achieve a hemodynamic response (r…

Il portale obliquo nel Palazzo Abatellis

2013

Il contributo analizza e commenta la presenza di un portalino obliquo, a imposte divergenti e non ortogonali alla giacitura del muro nel quale si inserisce, all'interno del quattrocentesco Palazzo Abatellis a Palermo. Interessante saggio di stereotomia moderna praticata in Sicilia a partire dal XV secolo sulla scorta di precedenti esperienze elaborate nel Levante iberico.

Pietro Novelli architetto. Disegni di portali e finestre

2013

Tra i disegni della collezione del barone Pietro Sgadari di Lo Monaco, oggi conservati presso la Galleria Interdisciplinare Regionale della Sicilia di Palazzo Abatellis (Palermo), figurano sette portali e una finestra attribuiti al noto pittore Pietro Novelli (1603 - 1647). I dettagli di alcuni portali - come quello di Santa Maria Maggiore nel quartiere Albergheria - richiamano le incisioni del secondo volume Della Trasportatione dell’obelisco vaticano… di Domenico Fontana (Napoli 1604); inoltre nel grafico S.L.M. Novelli 75 è possibile riconoscere il portale laterale di Santa Teresa alla Kalsa, in origine appartenente alla chiesa della Madonna delle Raccomandate, oggi non più esistente.

Computed Tomography of HCC

2016

Contrast-enhanced CT allows an accurate noninvasive diagnosis of Hepatocellular Carcinoma (HCC) nodules, and assessment of hepatic vascular anatomy and patency. The use of state-of-the-art equipment and of a tailored protocol is crucial. CT results help to detect and stage HCC, select the best treatment option, and evaluate response to therapy. In this chapter, the CT protocol for the cirrhotic liver, the CT features of HCC before and after treatment and of portal vein thrombosis will be described.

Transient hepatic nodular lesions associated with patent ductus venosus in preterm infants.

2010

We report on two cases of low-birth-weight preterm infants with patent ductus venosus associated with hepatic hypoechoic lesions of the fourth segment in an otherwise normal liver. Although tumorlike hepatic lesions have been previously reported in association with portosystemic shunts in children and adults, they were never described in preterm infants during physiological patency of ductus venosus. In our patients, hepatic lesions disappeared shortly after the spontaneous ductus closure. Physiopathologic interactions are discussed regarding altered portal blood supply caused by ductus venosus shunt.

Palazzo Alliata di Pietratagliata, già Termine

2013

Palazzo Termine Pietratagliata esemplifica bene, con le sue vicende plurisecolari, la storia complessa e stratificata della gran parte delle residenze nobiliari palermitane, risultato di una successione pressoché ininterrotta di interventi di ampliamento, di consolidamento strutturale, di ammodernamento distributivo degli interni, di aggiornamento stilistico degli apparati decorativi. Il suo portale, d'altro canto, appare come uno degli elementi del prospetto meno manomessi e con il suo sesto lievemente acusesto testimonia a quella data la lenta transizione verso l’architettura rinascimentale, lentezza ascrivibile al consapevole radicamento in Sicilia dei saperi e delle tradizioni costrutti…

Focal nodular hyperplasia-like lesions in patients with cavernous transformation of the portal vein: prevalence, MR findings and natural history.

2011

PURPOSE: To retrospectively investigate the prevalence, MR findings, natural history, and association with other hepatic lesions of focal nodular hyperplasia (FNH)-like lesions in a cohort of consecutive patients with cavernous transformation of the portal vein (CTPV). MATERIALS AND METHODS: This retrospective IRB-approved study comprised 58 patients (32 men, 26 women; average age, 50 years) with CTPV who underwent liver MR imaging between 2000 and 2008. MR images were assessed by two radiologists in consensus for the presence of (a) FNH-like lesions and other liver lesions, and (b) other imaging findings. Patients were assigned to a stable or progressive clinical course based on lesion cha…
