【摘要】目的探讨成人肠套叠的临床特点和诊治原则。方法对1980年1月至2004年2月期间我院收治的167例成人肠套叠临床资料进行回顾性分析。结果术前确诊79例,占47.3%。167例中159例行手术治疗,其中116例为肠道肿瘤,良性48例,恶性68例; 余51例为手术或外伤后、肠道炎症、盲肠过长等。共有117例行肿瘤根治性切除术或相应肠段切除术,50例行单纯复位或复位后固定术。2例术后死亡,余均恢复良好,134例随访2个月~10年,无肠套叠复发。结论提高对成人肠套叠的认识是诊断的关键,检查应选用B超、CT、钡灌肠等,治疗则首选手术治疗。
目的 总结分析普通B超监测引导PTCD方法改进后的优点及经验。方法 用普通B型超声诊断仪,腹部扇扫探头和国产配套的专用PTCD套针及引流管,改进监测引导PTCD的方法,总结分析其方法的优越性。结果 95例梗阻性黄疸患者PTCD成功率为100%,引流效果良好,并发症发生率为零。结论 用改进普通B超监测引导的方法进行PTCD,能克服在X线下进行PTCD的盲目性,对碘过敏者无禁忌,避免了长时间X线对人体的伤害。同时具有定位准确、费时少、成功率高、并发症少、价格便宜、适宜在基层医院推广应用等优点。
Objective To investigate the significance of urinary trypsinogen-2 dipstick test and the ratio of urinary amylase to urinary creatinine for the diagnosis of acute pancreatitis(AP).Methods A total of 57 consecutive patients who were suspected as AP presenting with abdominal pain at the emergency department experienced the test of serum and urinary amylase, urinary creatinine assay, urinary trypsinogen-2 dipstick and ultrasonography. Results There were 18 patients diagnosed as acute pancreatitis, the serum amylase assay had a sensitivity of 88.9 percent (cutoff value, 300 U per liter) and a specificity of 87.2 percent, the sensitivity and specificity of the urinary amylase assay and the ratio of urinary amylase to urinary creatinine were 88.9 (cutoff value, 2000 U per liter), 94.4 (cutoff value, 120 U per mmol Cr), 84.6 and 89.7 percent, respectively. The sensitivity and specificity of the urinary trypsinogen-2 test strip were 94.4 and 92.3 percent. The sensitivity of the ultrasonography were 88.9 percent. Conclusion Urinary trypsinogen-2 dipstick test is a good index for the diagnosis of AP. The ratio of urinary amylase to urinary creatinine is also a useful index and may be better than urinary amylase for the diagnosis of AP.
目的报告8例肝血管平滑肌脂肪瘤的影像学特征及病理学特点,探讨其诊断与治疗方法。方法对8例经手术及病理证实的肝血管平滑肌脂肪瘤的术前影像学表现(B超、CT、MRI、99mTcPMT)、手术情况及病理特点进行分析。结果B超: 肿瘤呈强回声光团6例,低回声光团2例; 边界清楚7例,血供丰富、内部回声不均匀4例,其中1例内部呈分隔网状结构。彩色Doppler超声示肿瘤血供丰富,均测及动脉频谱,阻力指数为0.4~0.5。静脉造影示肿瘤内血流信号明显增加。CT: 平扫示肿瘤呈低密度影7例,不均匀5例,边界清楚7例,肿瘤内见软组织影2例,脂肪成分2例。增强扫描示动脉期明显强化,门脉期及延迟期逐渐呈低密度。MRI: 肿瘤呈短T1、长T2信号,增强后强化明显,脂肪抑制后短T1变成长T1。99mTcPMT示肿瘤呈放射性增强,5 min相肿块区呈放射性缺损,2 h、5 h延迟相肿块区未见放射性填充,肝血池相肿块呈放射性填充。病理及免疫组化: 肿瘤由成熟的脂肪、血管及平滑肌组成,HMB45阳性。术前确诊3例。结论B超示强回声光团,CT呈低密度影中出现软组织影、脂肪成分,增强明显,MRI出现脂肪信号,脂肪抑制后短T1变成长T1,增强明显。99mTcPMT示肿瘤呈放射性增强,5 min相呈放射性缺损,延迟相未见放射性填充,肝血池相呈放射性填充。这些是肝血管平滑肌脂肪瘤的影像学特点,结合病史可作出诊断。此病应尽早手术治疗,行肝部分切除术。最后确诊依靠病理检查及免疫组化分析。
目的 评价B超引导下核心针活检术(CNB)对不可触及的乳腺病变(NPBL)的诊断价值。方法 采用18G Tru-cut针结合活检枪对88例患者的96个NPBL行B超引导下CNB,并与切除活检病理结果比较。结果 NPBL大小4~23mm(平均13.1mm)。在CNB中,86个为良性,2个为可疑恶性,6个为恶性,2个取材不良。在切除活检中9个为恶性,87个为良性。CNB可疑恶变的2个NPBL均为恶性,1个恶性NPBL误诊为乳腺腺病,取材不良的2个NPBL均为良性。本组NPBL中恶性病变占9.38%(9/96),B超引导下CNB对NPBL的良恶性诊断正确率为98.94%(93/94),诊断乳腺癌的敏感性为88.89%(8/9),特异性为100%(8/8),良性病变的病理诊断符合率为97.70%(85/87),取材不良为2.08%(2/96)。结论 B超引导下CNB对NPBL的诊断具有较高的敏感性和特异性,结果准确可靠。
During the past 54 months a total of 24 patients with secondary hepatic carcinoma have been treated by resection of hepatic metastasis and postoperation percutaneous intrahepatoportal chemotherapy(PHPC) under ultrasound guidance A followup from five months to four years shows that 21 patients have survivde for 5 to 48 months except 3 extremely advanced cases. The authors suggest that a combined therapeutic method for treating secondary hepatic carcinoma is more effective than either simple hepatectomy or chemotherapy.
Objective To evaluate the urine cytology silver staining combined with ultrasonography(USG)in the detection of bladder transitional cell carcinoma (TCC) recurrence after transurethral resection of bladder tumor(TURBT)in terms of sensitivity and specificity. Methods Cystoscopy was used as “gold standard”. Urine cytology combined with USG or cystoscopy was measured separately and blindly. AgNORs protein stained by silver were used in cytology with Kappa of inter-observers 0.81. For the USG, the patients were scanned with trans-rectal probe with Kappa of inter-observers 0.76. The results of urine cytology combined with USG (Positive when urine cytology and/or USG positive. Negative when both urine cytology and USG negative) were compared with “gold standard”. Results The 148 consecutive superficial TCC patients with TURBT one year previously were included in this study. Fifty seven recurrenced cases were detected. Recurrence rate was 38.51%. The sensitivity and specificity of urine cytology silver stain were 89.47% (95% CI 0.82 to 0.98) and 87.91% (95% CI 0.81 to 0.95). Area under ROC curve was 82.22%. The sensitivity and specificity of USG were 57.90% (95% CI 0.45 to 0.71 ) and 90. 11% ( 95% CI 0.84 to 0.96). Area under ROC curve was 73.13% . The sensitivity was improved to 94. 74% (95% CI 0.89 to 1.00) when cytology combined with USG. But specificity decreased to 84. 62% (95% CI 0.77 to 0.92 ). Area under ROC curve was improved to 98.28%. Conclusions Urine cytology silver stain combined with USG improves the high sensitivity for follow-up TCC patients after TURBT. The non-invasive protocol is suggested.
