Fusaroli, Pietro / Napoleon, Bertrand / Gincul, Rodica / Lefort, Christine / Palazzo, Laurent / Palazzo, Maxime / Kitano, Masayuki / Minaga, Kosuke / Caletti, Giancarlo / Lisotti, Andrea. ·Gastroenterology Unit, Hospital of Imola, University of Bologna, Bologna, Italy. · Department of Gastroenterology, Private Hospital Jean Mermoz, Lyon, France. · Trocadero Clinic, Paris, France. · Department of Gastroenterology and Hepatology, Kinki University Faculty of Medicine, Osaka-Sayama, Japan. ·Gastrointest Endosc · Pubmed #27311654.

ABSTRACT: BACKGROUND AND AIMS: The use of contrast-harmonic EUS (CH-EUS) in routine clinical practice is increasing rapidly but is not yet standardized. We present the levels of evidence (LEs) found in the literature to put its clinical outcomes in the appropriate perspective. METHODS: We conducted a systematic review of the available English-language articles. The LEs were stratified according to the Oxford Centre for Evidence-Based Medicine guidelines. RESULTS: Overall, 210 articles were included and presented according to different pathologic conditions. For pancreatic solid neoplasms, the pooled sensitivity and specificity in the diagnosis of pancreatic carcinoma were very high (LE 1); quantitative analysis and guidance of FNA were reported as investigational research (LE 2-3). For pancreatic cystic lesions, the identification of neoplastic solid components as hyperenhanced lesions represented a promising application of CH-EUS (LE 2). For lymph nodes, CH-EUS increased the diagnostic yield of B-mode EUS for the detection of malignancy (LE 2). For submucosal tumors, CH-EUS seemed useful for differential diagnosis and risk stratification (LE 2-3). For other applications, differential diagnosis of gallbladder and vascular abnormalities by CH-EUS were reported (LE 2-3). CONCLUSIONS: The LEs of CH-EUS in the literature have evolved from the initial descriptive studies to multicenter and prospective trials, and even meta-analyses. The differential diagnosis between benign and malignant lesions is the main field of application of CH-EUS. With regard to pancreatic solid neoplasms, the concomitant use of both CH-EUS and EUS-FNA may have additive value in increasing the overall accuracy by overcoming the false-negative results associated with each individual technique. Other applications are promising but still investigational.

2 Review Contrast enhancement and elastography in endoscopic ultrasound: an overview of clinical applications in pancreatic diseases. 2014

Serrani, M / Caletti, G / Fusaroli, P. ·Department of Medical and Surgical Sciences University of Bologna/Hospital of Imola, Imola, Italy - pietro.fusaroli@unibo.it. ·Minerva Med · Pubmed #25028864.

ABSTRACT: Endoscopic ultrasound is a very accurate imaging technique with a relevant clinical impact in the diagnosis and staging of various conditions such as pancreaticobiliary lesions, esophageal cancer, lung cancer, submucosal lesions and lymph nodes. Despite its increasing importance in everyday clinical routine, endoscopic ultrasound outcomes are still highly operator-dependent and tissue confirmation with fine needle aspiration is very often required for definitive differential diagnosis of tumors. Several techniques of image enhancement have been developed in recent years in the attempt to make the technique less operator-dependent. Among them the most important appear to be contrast harmonic-endoscopic ultrasound and endoscopic ultrasound-elastography. Contrast harmonic-endoscopic ultrasound is performed with a dedicated harmonic which displays the fine vascular network of both normal and pathological tissues after injection of an ultrasound contrast agent. Endoscopic ultrasound-elastography displays with different colors the differences in hardness between tissues, thus estimating elasticity in soft normal tissues which appear red and hard neoplastic tissues which appear blue. While contrast harmonic-endoscopic ultrasound has been introduced into clinical practice, endoscopic ultrasound-elastography mainly represents an investigational tool. The purpose of this paper was to review the mechanism of action and the clinical outcomes of contrast harmonic-endoscopic ultrasound and endoscopic ultrasound-elastography in pancreatic diseases. Both techniques show promising applications in the study of pancreatic tumors including differential diagnosis and providing guidance to fine needle aspiration.

3 Review Pancreatico-biliary endoscopic ultrasound: a systematic review of the levels of evidence, performance and outcomes. 2012

Fusaroli, Pietro / Kypraios, Dimitrios / Caletti, Giancarlo / Eloubeidi, Mohamad A. ·Department of Clinical Medicine, University of Bologna, 40100 Bologna, Italy. pietro.fusaroli@unibo.it ·World J Gastroenterol · Pubmed #22969187.

ABSTRACT: Our aim was to record pancreaticobiliary endoscopic ultrasound (EUS) literature of the past 3 decades and evaluate its role based on a critical appraisal of published studies according to levels of evidence (LE). Original research articles (randomized controlled trials, prospective and retrospective studies), meta-analyses, reviews and surveys pertinent to gastrointestinal EUS were included. All articles published until September 2011 were retrieved from PubMed and classified according to specific disease entities, anatomical subdivisions and therapeutic applications of EUS. The North of England evidence-based guidelines were used to determine LE. A total of 1089 pertinent articles were reviewed. Published research focused primarily on solid pancreatic neoplasms, followed by disorders of the extrahepatic biliary tree, pancreatic cystic lesions, therapeutic-interventional EUS, chronic and acute pancreatitis. A uniform observation in all six categories of articles was the predominance of LE III studies followed by LE IV, II b, II a, I b and I a, in descending order. EUS remains the most accurate method for detecting small (< 3 cm) pancreatic tumors, ampullary neoplasms and small (< 4 mm) bile duct stones, and the best test to define vascular invasion in pancreatic and peri-ampullary neoplasms. Detailed EUS imaging, along with biochemical and molecular cyst fluid analysis, improve the differentiation of pancreatic cysts and help predict their malignant potential. Early diagnosis of chronic pancreatitis appears feasible and reliable. Novel imaging techniques (contrast-enhanced EUS, elastography) seem promising for the evaluation of pancreatic cancer and autoimmune pancreatitis. Therapeutic applications currently involve pancreaticobiliary drainage and targeted fine needle injection-guided antitumor therapy. Despite the ongoing development of extra-corporeal imaging modalities, such as computed tomography, magnetic resonance imaging, and positron emission tomography, EUS still holds a leading role in the investigation of the pancreaticobiliary area. The major challenge of EUS evolution is its expanding therapeutic potential towards an effective and minimally invasive management of complex pancreaticobiliary disorders.

ABSTRACT: BACKGROUND: Endoscopic Ultrasound has been used in the clinical arena for almost 35 years and it is now well-integrated in everyday hospital practice. METHOD: We conducted a systematic review of the available English-language articles. OBJECTIVE: The purpose of this review is to summarize all the relevant indications to endoscopic ultrasound and analyze its relevant data in terms of accuracy and clinical outcomes. RESULTS: More than 5000 scientific papers published in the literature have demonstrated its high accuracy for the diagnosis and staging of a variety of benign and malignant conditions. Staging indications include gastroesophageal and rectal cancers. Diagnostic, staging and therapeutic indications include diseases of the pancreaticobiliary area. Finally, differential diagnosis of submucosal tumors represents another important indication to this technique.

5 Article Contrast Harmonic-Endoscopic Ultrasound Is Useful to Identify Neoplastic Features of Pancreatic Cysts (With Videos). 2016

ABSTRACT: OBJECTIVES: To evaluate the potential role of contrast harmonic endoscopic ultrasound (CH-EUS) in the differential diagnosis of pancreatic cysts and detection of malignancy. METHODS: Patients who underwent CH-EUS for evaluation of cyst wall, septae, and solid components of pancreatic cysts were included. The findings were compared to fine needle aspiration and surgery. RESULTS: Seventy-six patients were included. Serous and mucinous cysts were both hyperenhanced (86% and 89%, respectively; P = ns), whereas pseudocysts were hypoenhanced in 90% of the cases (P = 0.000004 vs serous cysts and P = 0.000005 vs mucinous cysts). Patients showing hyperenhanced solid components were finally diagnosed with malignancy (2 malignant intraductal papillary mucinous neoplasms, 2 cystic neuroendocrine tumors), in contrast to the patients with nonenhanced solid components who resulted to have either benign cysts with internal mucus clots (n = 10) or pseudocysts with internal debris (n = 8). CONCLUSIONS: CH-EUS allowed differentiation between pseudocysts and other pancreatic cysts but not mucinous versus serous cysts. Malignant vegetations inside pancreatic cystic lesions were clearly shown by CH-EUS as solid components with features of hyperenhancement, directing EUS-fine needle aspiration of potential neoplastic areas and avoiding puncture of debris and mucus plugs.

ABSTRACT: BACKGROUND AND AIMS: Endoscopic ultrasound-guided fine needle aspiration is routinely used in the diagnostic work up of pancreatic cancer but has a low sensitivity. Studies showed that Pancreatic Duodenal Homeobox-1 (PDX-1) is expressed in pancreatic cancer, which is associated with a worse prognosis. We aimed to verify whether the assessment of PDX-1 in endoscopic ultrasound-guided fine needle aspiration samples may be helpful for the diagnosis of pancreatic cancer. METHODS: mRNA of 54 pancreatic cancer and 25 cystic lesions was extracted. PDX-1 expression was assessed by Real-Time PCR. RESULTS: In all but two patients with pancreatic cancer, PDX-1 was expressed and was found positive in 7 patients with pancreatic cancer in which cytology was negative. The positivity was associated with a probability of 0.98 (95% CI 0.90-1.00) of having cancer and the negativity with one of 0.08 (95% CI 0.01-0.27). The probability of cancer rose to 1.00 (95% CI 0.97-1.00) for patients positive to both PDX-1 and cytology and fell to 0.0 (95% CI 0.00-0.15) in patients negative for both. CONCLUSIONS: PDX-1mRNA is detectable in samples of pancreatic cancer. Its quantification may be helpful to improve the diagnosis of pancreatic cancer.

7 Article Contrast harmonic endoscopic ultrasonography in the characterization of pancreatic metastases (with video). 2014

Fusaroli, Pietro / D'Ercole, Maria Cristina / De Giorgio, Roberto / Serrani, Marta / Caletti, Giancarlo. · ·Pancreas · Pubmed #24713844.

ABSTRACT: OBJECTIVE: The differential diagnosis between primary pancreatic neoplasms versus pancreatic metastases (PM) is challenging. Endoscopic ultrasonography with fine-needle aspiration can be used to differentiate primary versus metastatic tumors although with a suboptimal accuracy. Recently, contrast harmonic EUS (CH-EUS) has been reported as an adjunct in the diagnosis of pancreatic neoplasms. We evaluated the potential role of CH-EUS in the differential diagnosis of PM. METHODS: This study is a retrospective analysis of a prospectively maintained database. Of the 266 patients, 4.1% were diagnosed with PM. Endoscopic ultrasonography with fine-needle aspiration and/or surgical pathology represented our criterion standard. RESULTS: The origins of PM were renal cancer (3 patients), colon cancer(2 patients), breast cancer (2 patients), ovarian cancer (1 patient), melanoma(1 patient), lymphoma (1 patient), and sarcoma (1 patient). All lesions appeared hypoechoic at standard EUS. At CH-EUS, of the 11 lesions, 6 appeared hypoenhancing (colon cancer, sarcoma, and breast and ovarian cancer), 4 were hyperenhancing (renal cancer and lymphoma),and 1 was isoenhancing (melanoma). CONCLUSIONS: In our population, standard EUS features of PM were unremarkable. At CH-EUS, most of the PM appeared hypoenhancing suggesting a possible malignant origin. However, a subset of PM showed hyperenhancing pattern. In the appropriate context, particularly when cancer history is present, CH-EUS may add to the differential diagnosis and potentially spare endoscopic ultrasonography with fine-needle aspiration.

ABSTRACT: BACKGROUND AND AIM: Contrast harmonic endoscopic ultrasound (CH-EUS) was recently introduced to clinical practice; its reproducibility among endosonographers is unknown. Our aim was to assess the interobserver agreement (IA) in CH-EUS. METHODS: Fifteen endosonographers (eight experienced and seven non-experienced) from 11 Italian EUS centers evaluated 80 video-cases (40 solid pancreatic lesions, 20 pancreatic cystic lesions and 20 submucosal lesions) of CH-EUS, according to the degree of enhancement, the pattern of distribution and the washout of the contrast agent. IA within each group and between the two groups of observers was assessed with the Fleiss kappa statistic. RESULTS: Overall IA was moderate for the uptake and fair for the pattern of distribution and the washout. In solid pancreatic lesions, IA was moderate for the uptake and fair for the pattern and the washout. In cystic pancreatic lesions, IA was uniformly moderate for the assessment of uptake, slight for the pattern and fair for the washout. In submucosal tumors, IA was substantial for the uptake, slight for the pattern and fair for the washout. Non-experienced endosonographers demonstrated, in most cases, comparable IA with the experienced ones. CONCLUSIONS: Interobserver agreement among endosonographers for CH EUS was satisfactory. In particular, overall IA varied from slight to substantial, being fair in the majority of cases. Inherent structural features of the lesions, as well as technical differences between the variables assessed, could have accounted for the fluctuation of the results. Outcomes of IA were reproducible between experienced and non-experienced endosonographers.

10 Article Contrast harmonic echo-endoscopic ultrasound improves accuracy in diagnosis of solid pancreatic masses. 2010

Fusaroli, Pietro / Spada, Alessia / Mancino, Maria Grazia / Caletti, Giancarlo. ·Department of Clinical Medicine, GI Unit, University of Bologna/Aziendo Sanitaria Locale of Imola, Imola, Italy. p.fusaroli@ausl.imola.bo.it ·Clin Gastroenterol Hepatol · Pubmed #20417721.

ABSTRACT: BACKGROUND & AIMS: Contrast harmonic echo (CHE) has been developed for endoscopic ultrasound (EUS). This new technique detects echo signals from microbubbles in vessels with very slow flow, without artifacts. We assessed whether CHE-EUS increases the accuracy of diagnosis of pancreatic solid lesions. METHODS: At a tertiary-care EUS center, we examined 90 patients who were suspected of having pancreatic solid neoplasm. Radial and linear echoendoscopes were used with dedicated software for CHE. Sonovue (Bracco International BV, Amsterdam, The Netherlands) uptake, pattern, and washout were studied; data were compared for pancreatic lesions and adjacent parenchyma. The final diagnosis was obtained based on results of surgical pathology and/or EUS-fine needle aspiration (FNA) analyses. RESULTS: The finding of a hypoenhancing mass with an inhomogeneous pattern was a sensitive and accurate identifier of patients with adenocarcinoma (96% and 82%, respectively) (49 of 51 patients with primary pancreatic adenocarcinoma had a hypoenhancing mass that was inhomogeneous and had fast washout). This finding was more accurate in diagnosis than the finding of a hypoechoic lesion using standard EUS (P < .000). Hyperenhancement specifically excluded adenocarcinoma (98%), although sensitivity was low (39%). Of neuroendocrine tumors, 11 of 13 were non-hypo-enhancing (9 hyperenhancing, 2 isoenhancing). Interestingly, CHE-EUS allowed detection of small lesions in 7 patients who had uncertain standard EUS findings because of biliary stents (n = 5) or chronic pancreatitis (n = 2). Targeted EUS-FNA was performed on these lesions. CONCLUSIONS: Detection of a hypoenhancing and inhomogeneous mass accurately identified patients with pancreatic adenocarcinoma. CHE-EUS increased the detection of malignant lesions in difficult cases (patients with chronic pancreatitis or biliary stents) and helped guide EUS-FNA. A hyperenhancing pattern could be used to rule out adenocarcinoma.
