Objective To analyse the causes of missed diagnosis in colorectal cancers and improve the early diagnosis. Methods A retrospective analysis was made to investigate the cause of missed diagnosis in 380 cases suffering from colorectal cancers.Results Of the 1 020 patients treated in our hospital in the past ten years (1984-1993), 380 patients were missed diagnosed, with the missed diagnosis rate of 37.3%. The main causes included: ①lacking attention to the early symptoms of colorectal cancers, neglecting the need to conduct certain tests such digital rectal examination and stool occult blood examination, ②delaying of seeking medical advice on the part of the patients, ③being satisfied with the diagnosis and treatment of benign disease, and ④neglecting certain special tests such as enteroscopy and barium enema examination of colon.Conclusion Routine use of rectal touch, occult blood examination and necessary use of special tests such as enteroscopy, barium enema examination of colon in patients suffering from stool change will increase the rate of accurate diagnosis of colorectal cancer.
Objective To investigate the imaging characteristics of endometrial polyps by using transvaginal ultrasound and analyze the causes of misdiagnosis. Methods Fifty-seven patients pathologically diagnosed of endometrial polyps were retrospectively analyzed. Results The endometrial polyps had its own characteristics of ultrasound images, especially the lesion, size, shape, echo, border, color Doppler flow imaging (CDFI) and so on. Conclusion Endometrial polyps has some special features on ultrasound image. Inspection in the secretary period, along with endometrial hyperplasia of the merger as well as multiple myoma the merger may result in misdiagnosis.
目的 探讨宫颈癌漏诊的原因及特点，提高首诊诊断率。 方法 回顾性分析2009年1月－2011年3月收治的外院漏诊的65例宫颈癌患者临床资料。 结果 漏诊的65例中有51例误诊为宫颈糜烂，其中仅13例首诊曾行细胞学筛查，16例行阴道镜检查及活检，总平均年龄仅39岁，农村居民54例。 结论 各地区应加强宫颈癌筛查意识，采取相应措施及适合的筛查方式提高宫颈癌筛查率，减少漏诊。
【摘要】 目的 分析超声对腺性膀胱炎的误、漏诊原因，探讨减少其误、漏诊的方法。 方法 回顾性分析2006年1月-2010年2月经病理证实的135例腺性膀胱炎的声像图表现。 结果 135例腺性膀胱炎患者中，超声误诊26例，误诊率19.3%，漏诊11例，漏诊率8.2%。误诊的主要原因：乳头结节型和团块型与膀胱肿瘤声像图极为相似、容易混淆，超声医师对膀胱壁各层次的观察不仔细，对病史重视不够；漏诊的主要原因：膀胱充盈不佳或不充盈，病变体积太小、位于前壁或顶部，或病变位于膀胱后壁及颈部被明显增生的前列腺、膀胱内血凝块及膀胱结石等掩盖。 结论 超声是诊断腺性膀胱炎常用方法，但存在一定的误、漏诊，改进检查方法，可减少其误、漏诊发生。【Abstract】 Objective To analyze the reasons of missed diagnosis and misdiagnosis of glandularis cystitis by ultrasonography. Methods The sonographic outcomes of 135 patients with glandular cystitis diagnosed by pathological examination from January 2006 to February 2010 were retrospectively analyzed. Results In 135 patients, misdiagnosis was in 26 with a rate of 19.3%, missed diagnosis was in 11 with a rate of 8.2%. The reasons of misdiagnosis included: the sonographic outcomes of mastoid and tuberculous conglomeration were similar to those of bladder tumour; the ultrasonographic professionals didn’t clearly observe each layer of the bladder wall, and didn’t pay enough attention to the disease history. The reasons of missed diagnosis included: the bladder was under-filled or unfilled, the size of the lesions were too small and were located at the anterior wall or the top, and the lesions were located at the posterior wall and neck of the bladder which were covered up by obvious prostate hyperplasia,and gores or stones of bladder so that the lesions could not be observed. Conclusion Ultrasonography is a usual method for diagnosing glandular cystitis,and we should ameliorate the examination to decrease the misdiagnosis and missed diagnosis.
