Bottom Line: In subepithelial lesions of the stomach and duodenum, the visualization time (98.8±62.2 seconds vs 139.0±66.6 seconds, p=0.008) and image quality (4.1±1.3 vs 3.3±1.7, p=0.02) of FV-EUS were significantly superior to OV-EUS.FV-EUS may increase the ease of access to gastrointestinal subepithelial lesions compared to conventional OV-EUS.The performance of FV-EUS for evaluating pancreatobiliary diseases and performing interventions was comparable to conventional OV-EUS.

ABSTRACT

Background/aims: We aimed to evaluate the feasibility and efficacy of a forward-viewing linear endoscopic ultrasound (FV-EUS) in diagnostic EUS procedures compared to standard oblique-viewing EUS (OV-EUS).

Methods: This study was a prospective, randomized study that permitted cross-over. Fifty-one patients with subepithelial pancreatobiliary and upper gastrointestinal lesions underwent FV-EUS and OV-EUS sequentially, in random order. The EUS visualization was performed by a novice endosonographer, and the image quality of specific lesions was scored by an expert endosonographer. If fine-needle aspiration (FNA) was indicated, it was performed using both echoendoscopes by an expert endosonographer.

Results: Both of the EUS procedures had similar visualization times and image quality. In general, the visualization time was inversely related to the diameter of the specific lesions. In subepithelial lesions of the stomach and duodenum, the visualization time (98.8±62.2 seconds vs 139.0±66.6 seconds, p=0.008) and image quality (4.1±1.3 vs 3.3±1.7, p=0.02) of FV-EUS were significantly superior to OV-EUS. FV-EUS-guided FNA of pancreatic masses was successful in seven patients (87.5%).

Conclusions: FV-EUS may increase the ease of access to gastrointestinal subepithelial lesions compared to conventional OV-EUS. The performance of FV-EUS for evaluating pancreatobiliary diseases and performing interventions was comparable to conventional OV-EUS.

Mentions: In detail, the mean scores of image quality for pancreas head lesions of FV-EUS and OV-EUS were 4.4±0.6 and 4.4±0.6, respectively (p=1.00), and for pancreas body and tail lesions were 4.6±0.5 and 4.6±1.1, respectively (p=0.71). The image quality scores of FV-EUS and OV-EUS for subepithelial lesions of the stomach and duodenum were 4.1±1.3 and 3.3±1.7, respectively (p=0.02) (Fig. 2), and for gallbladder lesions were 3.3±1.9 and 4.2±1.6, respectively (p=0.1) (Table 4).
