  • Diagnosis and Treatment of Intussusception in Adults (Report of 167 Cases)

    【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。

  • A COMBINED TREATMENT FOR SECONDARY HEPATIC CARCINOMA

    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 followup 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.

  • ULTRASOUND GUIDED CORE-NEEDLE BIOPSY OF NONPALPABLE BREAST LESIONS

    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。

  • B超立体定位可提高颈内静脉穿刺置管成功率

    【摘要】 目的 总结B超引导下对深静脉穿刺置管的方法,减少并发症提高一次性穿刺置管成功率。 方法 2009年8月-2010年1月对99例患者,用超声探头探测颈内静脉,测得直径及皮下距离后,沿静脉纵轴从穿刺点向近心端两点或三点定位,并沿定位标记穿刺进针。 结果 B超定位下一定穿刺成功98例,无气、血胸、颈部血肿及神经损伤等并发症发生。 结论 B超定位能有效提高低年资医师颈内静脉一次性置管成功率,并能相对降低颈内静脉置管并发症。

  • Urine Cytology Silver Stain Combined with Ultrasonography in the Detection of Recurrence of Bladder Cancer

    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.
