本文根据810例低张双对比造影所发现的44例良性息肉和侵及粘膜,粘膜下层的早期大肠癌10例的大体形态及x线表现进行分析。良性息肉多见于40—49岁,早期癌多见于50一59岁。良性息肉1.0cm以下者90个(71％),而早期癌全部在1.5cm以上,在良好的双对比造影下,隆起性病变可分为四型:微隆型,无蒂型、亚有蒂型及有蒂型。大而表面不光滑的亚有蒂或无蒂者早期癌多见,小而光滑的有蒂或无蒂者良性偏多。
In this paper, the gross morphology and x-ray findings of 44 cases of benign polyps and invasive mucosa, submucosal early colorectal cancer, were analyzed based on 810 low contrast double contrast images. Benign polyps more common in 40-49 years old, early cancer more common in 50-59 years old. 90 (71%) patients with benign polyps below 1.0 cm, and all patients with early cancers above 1.5 cm, with good dual contrast angiography, uplift lesions can be divided into four types: micro-long, non-pedicle, sub-distribution Type and pedicle type. Large, non-smooth Asian pedicles or pedicles are more common in early cancers, and small, smooth pedicles or pedicles are more benign.
