The value of oral contrast-enhanced gastric ultrasonography in the diagnosis and staging of benign peptic ulcer

Abstract

We evaluate the value of oral contrast-enhanced gastric ultrasonography (OCUS) by comparing it with conventional gastroscopy in diagnosing and staging benign peptic ulcer. From July 2018 to December 2020, 44 patients with gastroscopy-confirmed benign peptic ulcers (a total of 45 ulcers were detected), who also received OCUS, were retrospectively reviewed. Each patient’s ultrasound images were compared with gastroscopy and pathology findings. The characteristics of ultrasonic images of different stages of ulcer were analysed. A total of 43 ulcers were detected by OCUS in 44 patients with benign peptic ulcers. There were no false positive results among the OCUS exams, but two ulcers were misdiagnosed. OCUS for benign peptic ulcer staging also shows acceptable clinical practice results. OCUS is useful for detecting and staging benign peptic ulcer, and may be considered an alternative method for conventional gastroscopy. OCUS is especially useful in the follow-up of BPU treatment, but futher study is needed to improve the diagnostic accuracy of benign and malignant ulcers.
