超声诊断剖宫产术后相关腹壁病变

目的探讨超声对剖宫产术后相关腹壁病变的诊断价值。方法回顾性分析47例剖宫产术后腹壁切口处不适并触及肿物患者的超声资料,记录病灶位置、形态、大小、边界、内部回声、坏死液化或钙化情况以及病变区血流信号。结果超声诊断21例为腹壁切口子宫内膜异位症,9例为炎性肉芽肿,7例为腹壁韧带样纤维瘤,4例为腹壁血肿,3例为脂肪液化,另3例为腹壁切口疝。结论超声对剖宫产术后相关腹壁病变的诊断与鉴别诊断具有重要价值。

腹壁病变的CT诊断

作者收集了28例经临床和病理证实的腹壁病变,对其CT表现进行了分析。CT扫描的价值在于确定病灶的来源、范围、内部结构及其与腹腔内脏器的关系,为临床治疗提供帮助。

高频超声在肝硬化及相关疾病诊断中的应用价值

目的探讨高频超声在肝硬化及相关疾病诊断中的应用价值。方法选取2013年1月-2015年1月在本院就诊的肝硬化患者144例,对其行常规超声检查,当常规腹部探头显示肝实质回声不均或肝脏浅表组织可疑病变时,加用高频线阵探头进行检查,并对检查出的15个被膜下结节行高频超声造影。结果发现肝被膜下结节92例,腹壁静脉曲张28例,肝细胞肝癌胸壁转移2例,脐疝6例。对其中15个结节行高频超声造影,诊断为肝细胞肝癌（HCC）10个,血管瘤2个,再生结节3个。高频超声诊断被膜下HCC的敏感性为80%,特异性为28.6%,准确性为47.0%。高频超声造影诊断被膜下HCC的敏感性为90%,特异性为71.4%,准确性为76.4%。结论高频超声检查可明显提高肝硬化及相关疾病的诊断正确率。

Reconstruction of the abdominal wall by using a combination of the human acellular dermal matrix implant and an interpositional omentum flap after extensive tumor resection in patients with abdominal wall neoplasm: A preliminary result

AIM:To present our trial using a combination of the human acellular dermal matrix (HADM) implant and an interpositional omentum flap to repair giant abdominal wall defects after extensive tumor resection. METHODS:Between February and October of 2007, three patients with giant defects of the abdominal wall after extensive tumor resection underwent reconstruction with a combination of HADM and omentum flap. Postoperative morbidities and signs of herniation were monitored. RESULTS:The abdominal wall reconstruction was successful in these three patients, there was no severe morbidity and no signs of herniation in the follow-up period. CONCLUSION:The combination of HADM and omentum flap offers a new, safe and effective alternative to traditional forms in the repair of giant abdominal wall defects. Further analysis of the long-term outcome and more cases are needed to assess the reliability of this technique.
