Abstract:
Objective To observe the efficacy and safety of CT-guided percutaneous biopsy of gastrointestinal space-occupying lesions.Methods Data of 116 patients with gastric,small intestinal or colorectal space-occupying lesions(totally 116 lesions)who underwent CT-guided percutaneous biopsy were retrospectively analyzed.The success rate of sampling was recorded.According to surgical pathology or follow-up results,the effectiveness of percutaneous biopsy,including the diagnostic sensitivity,specificity,accuracy and false negative rate were calculated.The impact of cavity wall thickness of the lesion(＜1 cm and≥1 cm),needle insertion depth(＜5 cm and≥5 cm)and puncture needle through gastrointestinal tract or not were observed and the related complications were recorded.Results All lesions were successfully sampled.The diagnostic sensitivity of percutaneous biopsy was 88.07%(96/109),with specificity of 100%(7/7),accuracy of 88.79%(103/116)and false negative rate of 11.93%(13/109).For lesions with cavity wall thickness≥1 cm and puncture needle insertion depth＜5 cm,the sensitivity and accuracy of puncture biopsy were higher(all P＜0.05),while the sensitivity and accuracy of puncture needle through gastrointestinal tract or not were not different(both P＞0.05).Slight bleeding around the lesions occurred in 12 cases(12/116,10.34%),but no other complications happened.Conclusion CT-guided percutaneous biopsy of gastrointestinal space-occupying lesions was effective and safe.
