  • Evaluation of Imaging Examinations in the Diagnosis of Periampullary Carcinoma

    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.

  • Evaluation of Imaging Examinations in Diagnosis of Malignant Obstructive Jaundice

    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 preoperative 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 preoperative diagnosis and assessing resectability.

  • 成人胰腺体尾部海绵状血管瘤1例报道并文献复习

    目的总结胰腺海绵状血管瘤的影像学表现及其相关临床特征。 方法回顾性分析四川省人民医院收治的经病理学检查确诊的1例胰腺海绵状血管瘤患者的临床及CT资料,分析其影像学表现及特点,并进行文献复习。 结果本例胰腺海绵状血管瘤患者的病灶位于胰腺体尾部,CT增强后其内分隔中度强化,并可见液-液平面,经病理学检查诊断为海绵状血管瘤。文献复习结果示:成人胰腺海绵状血管瘤好发于女性(14/19,占73.68%),发病年龄为23~79岁,平均49岁;最常见的症状为腹痛(12/18,占66.67%),发病部位最常见于胰头(8/19,占42.11%);通常为较大的囊性病灶,最大径从3~20 cm不等。胰腺海绵状血管瘤的诊断方法从20世纪60年代的腹部X线平片发展到现在应用较多的MRI及CT检查,最常用的检查方法仍然是CT检查(13/18,占72.22%)。 结论胰腺海绵状血管瘤是一种少见的囊性肿瘤,CT检查时动脉期并不一定会出现显著强化,并可因伴有囊内出血而出现液-液平面。

  • Research progress in imaging examination of inguinal hernia

    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.

  • 乳腺包裹性乳头状癌 3 例报道并文献复习

    目的总结乳腺包裹性乳头状癌(encapsulated papillary carcinoma,EPC)的临床病理学特征、诊断、鉴别诊断以及治疗方法,从而加深对 EPC 疾病的认识以及规范诊治。方法回顾性分析遵义医科大学附属医院 2012 年 1 月至 2018 年 11 月期间收治且经术后石蜡标本病理学检查明确诊断为 EPC 患者的临床资料,并结合相关文献总结其临床病理学特征以及治疗方法。结果共收集到 3 例患者,均为女性,年龄分别为 36 岁、50 岁、70 岁。其中 2 例以“发现乳腺肿块”就诊,肿块均为单发,边界清楚;另 1 例以“乳房胀痛伴乳头溢血溢液 2+ 年”入院。2 例患者的免疫表型为 Luminal 型,1 例免疫表型为三阴性型。 2 例 Luminal 型患者以手术治疗为主,而三阴性型以手术治疗及术后化疗为主。3 例患者目前在随访中、无复发及转移。结论乳腺 EPC 是厚的纤维囊壁包裹且囊壁肌上皮缺乏特殊亚型的浸润性癌,预后较好。其中 Luminal 型 EPC 的治疗原则同导管原位癌(ductal carcinoma in situ,DCIS),而三阴性型 EPC 的治疗参照传统型浸润性乳腺癌。

  • Clinical study of imaging and rapid pathology in diagnosis and treatment of pancreatic cystic neoplasm

    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.
