Endoscopic biopsy is thought to be the best method to obtain biopsy samples of the gastrointestinal tract. In our case, however, an endoscopic forceps biopsy failed to confirm malignancy of an intramural gastric tumour. Since the tumour, about 4 cm in diameter, was well delineated on the CT scan, the patient was referred for a percutaneous CT-guided needle biopsy, which confirmed a gastrointestinal stromal tumour.
内镜活检被认为是获取胃肠道活检样本的最佳方法。然而，在我们的病例中，内镜钳取活检未能确诊胃壁内肿瘤的恶性性质。由于直径约4厘米的肿瘤在CT扫描上边界清晰，该患者被转诊进行经皮CT引导下针吸活检，结果确诊为胃肠道间质瘤。
