Pancreatic malignant tumor is one of the common malignant tumors in clinical practice. Due to the early stage of pancreatic malignant tumor, the onset is relatively insidious and patients often do not have obvious clinical manifestations. Most of the patients once discovered pancreatic malignant tumor are in the middle and late stage of the tumor, which misses the best time for surgical treatment. So what are the methods of adjuvant examination for pancreatic malignant tumor, here is a study for you. The main clinical examination methods for pancreatic malignant tumor are the following: 1. Because of its simplicity, non-invasiveness and reproducibility, color ultrasound is clinically preferred for screening pancreatic malignant tumors. However, since the pancreas is a retroperitoneal organ, the pneumatosis of the intestinal ducts may interfere with the early diagnosis of pancreatic malignant tumors. 2.CT examination. CT examination of abdomen is not affected by pneumatization of intestinal ducts, but it has certain radiation. CT of pancreas can clearly show the outline of pancreas, especially combined with enhanced CT examination of pancreas can find small lesions of 1 cm in diameter. 3.Enhanced magnetic resonance examination. Magnetic resonance examination can show the volume, size and location of the lesion in the pancreas through different imaging levels. In combination with contrast enhancement examination, smaller tumor lesions can be detected. MRI is more accurate than CT, and there is no radiation in MRI, but the duration of MRI is longer and noisier, which is often not tolerated by patients with mental abnormalities. 4.Ultrasound endoscopy. At present, ultrasound endoscopy can not only clarify the specific location of pancreatic lesions, but also perform puncture biopsy to clarify the nature of the lesions, which is increasingly widely used in clinical practice.
