Combined endo-laparoscopic treatment of large gastrointestinal stromal tumor of the stomach: Report of a case and literature review
2020
Highlights • We report a case of 75-year-old Caucasian men with unknown voluminous gastric GIST, who came to our attention complaining melena. We decided to perform a laparoscopic-endoscopic combined surgical approach. • Intraoperative endoscopy identified gastric GIST and confirmed the submucosal origin and the integrity of the capsule. A 10 cm laparoscopic gastrotomy was carried out along the gastric found in order to realize a laparo-endoscopic rendez-vous technique. • Laparoscopy has rapidly become a preferable approach for gastric GISTs surgical treatment. The magnified view and the lesser invasiveness of laparoscopic technique allow the surgeon to perform a more meticulous dissection,…
A New Sampling Method for Spleen Stiffness Measurement Based on Quantitative Acoustic Radiation Force Impulse Elastography for Noninvasive Assessment…
2014
In our study, we evaluated the feasibility of a new sampling method for splenic stiffness (SS) measurement by Quantitative Acoustic Radiation Force Impulse Elastography (Virtual Touch Tissue Quantification (VTTQ)).We measured SS in 54 patients with HCV-related cirrhosis of whom 28 with esophageal varices (EV), 27 with Chronic Hepatitis C (CHC) F1–F3, and 63 healthy controls. VTTQ-SS was significantly higher among cirrhotic patients with EV (3.37 m/s) in comparison with controls (2.19 m/s,P<0.001), CHC patients (2.37 m/s,P<0.001), and cirrhotic patients without EV (2.7 m/s,P<0.001). Moreover, VTTQ-SS was significantly higher among cirrhotic patients without EV in comparison with bot…
Non-invasive prediction of esophageal varices by stiffness and platelet in non-alcoholic fatty liver disease cirrhosis.
2018
Background & Aims: Baveno VI and expanded Baveno VI criteria can avoid the need for esophagogastroduodenoscopy (EGD) to screen for varices needing treatment (VNT) in a substantial proportion of compensated patients with viral and/or alcoholic cirrhosis. This multicenter, cross-sectional study aims to validate these criteria in patients with compensated cirrhosis due to non-alcoholic fatty liver disease (NAFLD), accounting for possible differences in liver stiffness measurement (LSM) values between M and XL probes. Methods: We assessed 790 patients with NAFLD-related compensated cirrhosis who had EGD within six months of a reliable LSM, measured by FibroScan® using M and/or XL probe. Baveno …
Is Transient Elastography Needed for Noninvasive Assessment of High-Risk Varices? The REAL Experience
2019
INTRODUCTION: The Baveno VI consensus guidelines and an expanded algorithm suggest that transient elastography (TE) and platelet (PLT) count can be used to identify patients with cirrhosis who can avoid esophagogastroduodenoscopy (EGD). The primary aims of this study were to assess the ability of a simple algorithm, which uses only laboratory parameters, to predict medium/large esophageal varices (EV) in patients with hepatitis C virus (HCV) and cirrhosis from the Rete Sicilia Selezione Terapia-HCV (RESIST-HCV) cohort and to compare the performance of the algorithm with Baveno VI and Expanded Baveno VI criteria. The secondary aim was to assess the role of TE in ruling out large EV. METHODS:…
The duodenum in liver cirrhosis: endoscopic, morphological and clinical findings.
1991
Endoscopic studies were performed to determine whether changes occurred in the duodenum related to portal hypertension in patients with liver cirrhosis. The total of 271 patients studied were subdivided into three groups: 83 patients with liver cirrhosis and portal hypertension, 53 with liver cirrhosis but no portal hypertension, and 135 controls. In the duodenum of cirrhotic patients with portal hypertension several changes were observed on endoscopy that were also present in the other two groups. Atrophy and vascular malformations, however, were present only in the duodenum of cirrhotic patients with portal hypertension, although in only a few patients and with statistical significance on…
Insulin resistance is a risk factor for esophageal varices in hepatitis C virus cirrhosis
2008
Indirect methods to predict the presence of esophageal varices (EV) in patients with cirrhosis are not sensitive enough to be used as a surrogate for endoscopy. We tested the effectiveness of liver stiffness measurement (LSM) by transient elastography and the presence of insulin resistance (IR), a marker associated with fibrosis progression, in the noninvasive prediction of portal hypertension. One hundred four consecutive patients with newly diagnosed Child A hepatitis C virus (HCV) cirrhosis underwent upper gastrointestinal endoscopy to search for EV. Clinical, anthropometric, biochemical, ultrasonographic, and metabolic features, including IR by the homeostasis model assessment (HOMA), a…
Oesophagogastroduodenoscopy in patients with cirrhosis: Extending the range of detection beyond portal hypertension
2010
Background: Oesophagogastroduodenoscopy is currently recommended for the screening of varices in cirrhosis. In addition to the assessment of varices, oesophagogastroduodenoscopy can detect conditions that, while unrelated to portal hypertension, may require treatment. Aims: We evaluated in a large cohort of cirrhotic patients the prevalence of upper digestive findings other than oesophagogastric varices, the associations between upper gastrointestinal findings, portal hypertension and features of cirrhosis, and the incidence of new lesions in the course of a surveillance program. Methods: Analysis of the records of 611 consecutive cirrhotic patients undergoing oesophagogastroduodenoscopy fo…
StellaTUM: current consensus and discussion on pancreatic stellate cell research
2011
The field of pancreatic stellate cell (PSC) biology is very young, as the essential in-vitro tools to study these cells (ie, methods to isolate and culture PSC) were only developed as recently as in 1998. Nonetheless, there has been an exponential increase in research output in this field over the past decade, with numerous research groups around the world focusing their energies into elucidating the biology and function of these cells. It is now well established that PSC are responsible for producing the stromal reaction (fibrosis) of two major diseases of the pancreas—chronic pancreatitis and pancreatic cancer. Despite exponentially increasing data, the methods for studying PSC remain var…
Mini-laparoscopy in the endoscopy unit: Safety and outcomes in over one thousand patients
2011
AIM: To investigate the safety of consecutive mini-laparoscopy guided liver biopsies for the diagnosis and staging of liver diseases. METHODS: In this study we retrospectively analyzed the safety of mini-laparoscopic liver biopsy performed in an endoscopy unit in 1071 patients. We measured the incidence of bleeding and evaluated the management and outcome of bleeding interventions. RESULTS: The most common etiologies of liver injury were viral hepatitis and autoimmune liver disease. 250 patients had macroscopically and histologically proven cirrhosis. 13 patients had no pathological findings. 33% of all patients had bleeding that required argon plasma coagulation of the puncture site during…
Diagnostic and Therapeutic Role of Endoscopy in Crohn’s Disease
2015
Endoscopy plays a very important role in the management of Crohn’s disease (CD). It is an extremely important diagnostic tool in the period of symptoms onset, allowing the evaluation of the activity and of the extent of the disease; moreover, it is very useful in follow-up giving an evaluation of the response to the medical therapy, a detection of recurrences following surgery, and providing an oncological screening. Several procedures like traditional colonoscopy, single- and double-balloon enteroscopy, endocapsule examination, and endoscopic ultrasound are today available. CD can be diagnosed with endoscopy by a skilled gastroenterologist in the setting of a suggestive clinical presentati…
