腹腔镜技术作为早期结直肠癌的一种极佳疗法已被广为接受。当癌明显侵及肠壁浆膜表面时,术中易于识别;但当病变侵袭深度仅限于浆膜下时,则很难辨认。对这种病例术中贯于采用结肠镜检法。但在腹腔镜术中此法很难进行,因病人通常仰卧在手术台上,不允许经肛门结肠途径行病变部位结肠镜鉴定。现介绍一种解决该问题的新方法——术前以结肠镜将活性碳颗粒注入病变周围的肠壁作为癌瘤位置的标 Laparoscopic techniques have been widely accepted as an excellent treatment for early stage colorectal cancer. When the cancer apparently invades the serous surface of the intestinal wall, it is easy to identify during surgery; however, when the invasion depth of the lesion is limited to the subserosa, it is difficult to identify. Colonoscopy was used throughout this case. However, this method is difficult to perform in laparoscopic surgery, because the patient is usually supine on the operating table, colonoscopy through the anal colon path lesions can not be identified. A new method to solve this problem is introduced - Preoperative colonic lens injection of activated carbon particles into the intestinal wall surrounding the lesion as a marker for the location of the tumor
