| 1 | MR弹性成像对正常胰腺评价及胰腺占位性病变鉴别的临床价值显示文摘目的探讨正常胰腺和胰腺占位性病变,在磁共振弹性成像(MRE)检测中的平均弹性值差异鉴别胰腺占位性病变的诊断有效性。方法选取我院收治的胰腺肿瘤患者68例,其中胰腺导管腺癌40例,良性占位28例。另纳入同期体检健康志愿者20例为对照组。全部观察对象接受3.0T MR弹性成像检查,共振频率设定为40 Hz。结果胰腺癌组织的平均弹性值为4.33±1.69,胰腺良性占位平均弹性值为1.93±0.86,正常胰腺组织的平均弹性值为1.13±1.10,组间差异具有统计学意义(P<0.05);以弹性值≥1.325 kPa为诊断良性胰腺占位的ROC曲线下面积为0.748,敏感性为71.4%,特异性为100.0%;以弹性值≥3.310 kPa为鉴别良、恶性胰腺占位的ROC曲线下面积为0.871,敏感性为75.0%,特异性为89.3%。结论MRE可以通过测定组织弹性,有效区分正常胰腺及胰腺占位性病变的良、恶性,对鉴别诊断具有较高的临床应用价值。 | 翟所席 任翠芳 毕研翠 王乃武 | 2021 | 医学影像学杂志2021，31，11： | 4 |
| 2 | Endoscopic ultrasound-guided drainage of pancreatic fluid collections: The impact of evolving experience and new technologies in diagnosis and treatment over the last two decades显示文摘Background: Endoscopic ultrasound (EUS)-guided drainage is the preferred approach for drainage of pan- creatic uid collections (PFCs) due to the better experience and signi cant progress using newer stents and access devices during last decade. This study aimed to evaluate the role of the evolving experience and possible in uence of new technological devices on the outcome of patients evaluated for PFCs and submitted to EUS-guided drainage during two different periods: the early period at the beginning of experience when a standardized technique was used and the late period when the increased experience of the operator, combined with different stents quality were introduced in the management of PFCs. Methods: We retrospectively analyzed the clinical data of a cohort of 91 consecutive patients, who underwent EUS-guided drainage of symptomatic PFCs from October 2001 to September 2017. Demographic, therapeutic results, complications, and outcomes were compared between early years’ group (2001 2008) and late years’ group (2009 2017). Results: Endoscopic treatment was successfully achieved in 55.6% (20/36) of patients in the early years’ group, and in 96.4% (53/55) in the late years’ group. Eighteen patients (12 in early years’ and 6 in the late year’s group) required additional open surgery. Procedural complications were observed in 5 patients, 4 in early years’ and 1 in late years’ group. Mortality was registered in two patients (2.2%), one for each group. Conclusions: During our long-term survey using EUS-guided endoscopic drainage of PFCs, signi cantly better outcomes in term of improved success rate and decrease complications rate were observed during the late period. | Pietro Gambitta Anna Maffioli Jean Spiropoulos Antonio Armellino Maurizio Vertemati Paolo Aseni | 2020 | Hepatobiliary & Pancreatic Diseases International2020，19，1： | 1 |
