Methods From 15th to 16th April, 2010, 83 patients who were injured in Yushu Earthquake underwent CT or DR examinations. Results In 83 patients, chest injury was found in 33, limb injury was in 32, spinal injury was in 22, pelvic injury was in 15, head and maxillofacial injuries were in 12, abdominal injury was in seven,and single soft tissue injury was in 13. Conclusion Radiological examination can exactly, quickly and effectually diagnose the injuries caused by the earthquake.
ObjectiveTo evaluate the imaging examination in the diagnosis of periampullary carcinoma. MethodsA retrospective analysis of 125 patients with pathologically proven periampullary carcinomas enrolled in Zhongshan hospital between Jan. 1991 and Dec. 2000. ResultsThe accuracy of BUS or CT was higher than that of ERCP in patients with pancreatic head carcinoma (P=0.044,P=0.029, respectively). The accuracy of ERCP was higher than that of BUS or CT in patients with duodenal papillary carcinoma (P=0.005,P=0.03, respectively). The accuracy of ERCP was higher than that of BUS or CT in patients with ampullary carcinoma (P=0.157,P=0.282, respectively). The accurary of MRCP was 8/8,8/9 respectively in patients with duodenal papillary carcinoma and ampullary carcinoma. ConclusionBUS+CT is the manner of choice in the diagnosis of pancreatic head carcinoma, ERCP is suitable for nonpancreatic periampullary cancer. MRCP should be applied widely in the near future.
ObjectiveTo study the diagnostic value of imaging examinations and their accuracy in evaluating the malignant obstructive jaundice and their resectability. MethodsThe clinical data of 674 malignant obstructive jaundice within 10 years were collected and analyzed.ResultsFor BUS, CT, PTC, ERCP and MRCP, the preoperative accuracy in malignant obstructive jaundice were 74.0%, 86.5%, 88.4%, 92.9% and 94.0%, while the ratio of actual removals in those who had been assessed removable preoperatively were 63.4%, 68.5%, 86.8%, 87.3% and 93.9%, respectively. Conclusion MRCP， PTC, CT and ERCP are better than BUS in the diagnosis of malignant obstructive jaundice (P＜0.05 vs. P＜0.01), while MRCP，ERCP and PTC are much better than BUS and CT in evaluating resectability (P＜0.01). Combination of two or more imaging examinations can improve the accuracy of preoperative diagnosis and assessing resectability.
目的 探讨脾占位性病变的临床诊断特点和治疗对策。方法 回顾性分析68例脾占位性病变患者的临床资料。结果 超声和CT是诊断脾占位性病变的主要方法。68例脾占位性病变中良性48例，恶性20例。手术治疗47例，其中脾切除37例，脾切除加胰尾切除2例，脾部分切除3例，脾切除加脾窝引流4例，单纯脾囊肿去顶减压1例。1例脾脓肿行脾切除术后发生肺部感染，经抗感染治疗后痊愈； 1例脾脓肿行脾切除术后，发生脾窝脓肿，感染严重，被迫再次开腹行脓肿引流术，其余良性病变经手术治疗后效果好； 恶性病变术后效果差。结论 脾占位性病变良性多见，恶性少见； 影像学检查是诊断脾占位性病变的主要手段。脾切除对成年人是一种有效的治疗方法，良性预后好，恶性预后差； 对儿童、青少年脾良性病变，脾部分切除是一种很好的选择。
ObjectiveTo discuss the main auxiliary inspection methods and their guiding significance for inguinal hernia.MethodsBy searching literatures and international guidelines, to review the main auxiliary examination methods, such as ultrasound, CT, and MRI.ResultsClinical physical examination combined with ultrasound could increase diagnostic sensitivity. CT could provide surgeons with a better sense of wholeness and structural details, and could be used as a guide for specific types of inguinal hernia. The soft tissue recognition of MRI was good, and it had a good effect on the identification of hidden hernia, mesh conditions, and tissue inflammation.ConclusionEach examination has its own advantages, and should be selected based on clinical practice and medical center conditions.
ObjectiveTo investigate the guiding value of preoperative imaging and intraoperative rapid pathology in the diagnosis and treatment of pancreatic cystic neoplasm (PCN).MethodsThe clinical data of 205 patients with PCN diagnosed by pathology from July 14, 2003 to July 31, 2018 were analyzed retrospectively. The precise and fuzzy diagnostic rate and misdiagnosis rate of PCN by preoperative imaging and intraoperative rapid pathology were analyzed.ResultsThe most commonly used preoperative imaging methods were ultrasound and CT, in 146 cases (82.95%) and 141 cases (80.11%), respectively. There were 54 cases (30.68%) with MRI. Of them, 47 cases were examined by single examination, 129 cases received combined examination, of which 123 cases (95.35%) were examined by ultrasound combined with CT. The precise and fuzzy diagnostic rate of PCN by ultrasound, CT, and MRI were 81.51% (119/146), 81.56% (115/141), and 87.04% (47/54), respectively. Comparison of ultrasound with CT and MRI showed statistical significance (χ2=47.747, P<0.001; χ2=11.873, P=0.018), but no significant difference was observed between CT and MRI (χ2=5.012, P>0.05). In 27 cases of false diagnosis by ultrasound, no obvious abnormality was found in 14 cases (51.85%), followed by misdiagnosis as pancreatic pseudocyst (11 cases, 40.74%). Of the 26 cases misdiagnosed as pancreatic cancer by CT, 57.69% (15 cases) were misdiagnosed as pancreatic cancer; 7 cases were misdiagnosed by MRI, 42.86% (3 cases) of patients were misdiagnosed as pancreatic cancer and pancreatic pseudocyst. Thirty-one cases were misdiagnosed by intraoperative rapid pathology, and most of them misdiagnosed as pancreatic pseudocyst (10 cases, 32.26%). The next was SPN misdiagnosed as pancreatic neuroendocrine tumor (7 cases, 22.58%). The precise and fuzzy diagnostic rates of PCN were 81.58% (124/152), 86.84% (132/152), and 97.37% (148/152) in preoperative imaging, intraoperative rapid pathology, and preoperative imaging combined with intraoperative rapid pathology, while the misdiagnostic rates were 18.42% (28/152), 13.16% (20/152), and 2.63% (4/152), respectively.ConclusionsIn preoperative imaging and intraoperative rapid pathological examination, it is possible that ultrasound could not find PCN lesions. CT and MRI are most likely to be misdiagnosed as pancreatic cancer. Intraoperative rapid pathological examination misdiagnosed as pancreatic pseudocyst is most common. Perfect preoperative imaging and rapid intraoperative pathology can improve the correct diagnosis rate of PCN and avoid unreasonable surgical intervention measures.
