450例青年人纤维结肠镜检出大肠癌11例分析

Analysis of 11 Cases with Colonic Cancer Detected in 450 Young Patients Undergoing Fibrocolonoscopic Examination

我们从１９８７年８月～１９９４年８月共进行１９３８例次纤维结肠镜检查，经病理证实大肠癌共１０８例，检出率５５７％，其中３５岁以下４５０例，病理证实青年大肠癌１１例，检出率２４４％。青年大肠癌占大肠癌总数的１０１９％。青年大肠癌１１例中，男７例，女４例，男∶女＝１７５∶１，２０岁１例，２１～２５岁４例，２６～３０岁１例，３１～３５岁５例。大肠癌发生在直肠６例（５４５５％），乙状结肠３例（２７２７％），横结肠１例（９０９％），升结肠１例（９０９％）。主要临床症状依次为血便、腹痛、腹泻、粘液便，病程平均１１３个月。病理分类：腺癌７例（６３６４％），息肉腺瘤恶变３例（２７２７％），乳头状腺癌１例（９０９％）。本组直肠癌６例作肛门指诊，均能触及病灶。

From August 1989 to August 1994,11 cases of colonic cancer were detected in 450 young patients (age<35 years).Among these patients with colonic cancer,male:female=1 75∶1,the age distribution:20 years old 1 case,21～25 years old 4 cases,26～30 years old 1 case and 31～35 years old 5 cases.The localization of colonic cancer:in rectum 6 cases (54 55%),in sigmoidal colon 3 cases (27.27%),in transversal colon 1 case (9.09%) and in ascending colon 1 case (9.09%).The major clinical symptoms included hematochezia,abdominal pain,diarrhea,mucous feces.The pathological classifcation:adenocarcinoma 7 cases feces.The pathological classification:adenocarcinoma 7 cases (63.64%),polypoid adenocarcinoma 3 cases (27.27%),papillary adenocarcinoma 1 case(9.9%).Based on above analysis,fibrocolonocopic examination should still be done for the young people with high risk to find out the colonic carcer,even if the rectal palpation is inconspicuous.
