The diagnostic efficiency of ultrasound-guided biopsy of gastrointestinal lesions

Objective To explore the diagnostic efficiency of ultrasound-guided biopsy in the diagnosis of gastrointestinal lesions. Methods The study retrospectively analyzed 41 cases who underwent ultrasound-guided biopsy and diagnosis were confirmed as gastrointestinal lesions either by surgery resections or by biopsies in our hospital from January 2006 to April 2018. The detection rate and the safety in the diagnosis of gastrointestinal lesions by ultrasound-guided biopsy were evaluated and they were compared with clinical efficiency of the endoscopic biopsy. Results ⑴ Of the 41 cases underwent ultrasound-guided biopsies, 38 cases were confirmed by pathology. A 92.7% detection rate had achieved by ultrasound-guided biopsies. In the 38 cases, the diagnoses were grouped in benign and malignant, with 29 malignant and 9 benign. ⑵ Among the 13 cases examined by both of the ultrasound-guided biopsy and endoscopic biopsy, the diagnostic accuracy of ultrasound-guided biopsy was 84.6% and 61.5% with endoscopy. No significant difference (P=0.378) between the two modalities. ⑶ No complication occurred with both of methods. Conclusions Ultrasound-guided biopsy of gastrointestinal lesions is a safe and effective method. It would be an alternative solution to provide clinicians with reliable diagnosis, especially when endoscopic diagnosis is not inapplicable or failed.
