FV-EUS Endoscope Versus CLA-EUS for EUS-FNA of Solid Lesions

Not Applicable

Completed

• Conditions: Solid Lesions of the GI Tract or of Adjacent Organs
• Interventions: Device: EUS-guided fine needle aspiration

• Registration Number: NCT01673945
• Lead Sponsor: Catholic University of the Sacred Heart

Brief Summary

The intent of this study is to compare the performance of the CLA-EUS versus the FV-EUS in the performance of EUS-FNA of patients with solid lesions of the GI tract and of adjacent organs, with the aim of establishing for which lesions and from which location the capability of the FV-EUS will be superior, equal or, inferior to the CLA-EUS

Detailed Description

Recently, a forward viewing linear echoendoscope (FV-EUS) has been developed with the aim of potentially expanding the therapeutic applications of EUS. This prototype is a modification of the CLA scope and it is characterized primarily by a shifting of the orientation of the endoscopic and US views from oblique to forward. The US transducer is located adjacent to the working channel, at the endoscope tip, to display a forward-viewing image along to a scanning plane that is parallel to the insertion direction with a 90° scanning range. It has a 3.7 mm working channel without elevator, which allows exit of the FNA needle or any other accessory used parallel to the longitudinal axis of the scope.

Preliminary experiences with this scope have reported potential advantages over the conventional linear scope (CLA-EUS) for pseudocysts drainage and for hilar biliary strictures. Moreover, a large experience still unpublished from the Catholic University, Rome, Italy in the use of the FV-EUS for FNA of solid and cystic lesions throughout the GI tract has shown the FV-EUS to be highly effective with a performance that seems at least comparable to that of the CLA-EUS. To date, however, no data comparing the performance of both scopes for FNA of target lesions are available to better clarify the advantages and disadvantages of one scope over the other.

We designed a randomized comparative trial in which patients will be randomized to undergo examination with CLA-EUS or with FV-EUS. In case of failure of: (i) visualization of the presumed lesion; (ii) failure in performing the FNA with the scope used based on randomization, a second attempt will be made using the other scope.

Arm && Interventions

Group	Intervention	Description
EUS-FNA with the CLA-EUS	EUS-guided fine needle aspiration	patients examined with the CLA-EUS
EUS-FNA With the FV-EUS	EUS-guided fine needle aspiration	patients examined with the FV-EUS

Primary Outcome Measures

Name	Time	Method
Technical performance of the CLA-EUS versus FV-EUS for EUS-FNA	6 months	(i)Successful lesion identification. (ii)Successful execution of EUS-FNA proved by EUS image confirming the needle into the lesion.

Secondary Outcome Measures

Name	Time	Method
Rate of complications	1 month	Rate of bleeding, pancreatitis, infection and perforation for each procedure will be measured by observation of the patient in the recovery area soonafter and one hour after completion of the procedure. The rate of pancreatitis and infection rate will be also assessed at 24 hours by visiting or calling the patients if discharged
Diagnostic performance of the CLA-EUS versus FV-EUS for EUS-FNA	6 months	sensitivity, specificity, and diagnostic accuracy of EUS-FNA performed with the two different EUS scopes in the evaluation of solid lesions will be determined and compared
Ease of procedure	6 months	Ease of the procedure will be graded on a analog 5 point score as listed in the table below.; Physician will be asked to answer the following questions: * Ease of visualization?; * Ease of puncturing?; * Ease of moving back and forth inside the lesion?; * Ease of overall procedure?
