ObjectiveTo determine the characters of symptomatic pancreatic pseudocyst due to acute pancreatitis and effects of surgical treatment with two kinds of procedure (internal drainage or external drainage). MethodsOne hundred and fifteen cases hospitalized during recent ten years were retrospectively analyzed.ResultsWe found that necrotic tissue existed in the pseudocyst in most cases and infection might occur in these pseudocyst. Although effect of two kinds of surgery was similar, the clinical course was different. The complications after surgery were fewer in patients underwent internal drainage than that with procedure of external drainage, and average hospital day was 7d in cases with internal drainage and 11d in cases with external one respectively. Surgery of internal drainage used in treatment was not only successful in noninfectious and single pseudocyst, but in infectious or multiple seudocyst.ConclusionInternal drainage should be used in most cases and considered as the first selection in surgery of pseudocyst due to acute pancreatitis.

ObjectiveTo study the clinical manifestation, radiographic characteristics, and treatments of reactive lymphoid hyperplasia(RLH) of liver. MethodsThe clinical data and treatment process of 1 patient with RLH of liver in our hospital was analyzed retrospectively, and the other 49 cases reported in English literature were reviewed. ResultsThere were 33 pieces of case reports found in PubMed database. For all 50 patients, there were 45 female(90%) and 5 male(10%) patients, and the mean age was(57.6±14.0) years(15-85 years). Only 8 patients(16%) were discovered with multiple mass, the rest of them were solitary mass(84%). Of the 50 patients, 6 patients(12%) were discovered because of bellyache, 2 patients(4%) were discovered during operation, 2 patients(4%) were discovered by pathological examination after liver transplantation, 1 patient(2%) was discovered during autopsy, 39 patients were discovered during examination or reexamination. The tumors were located in the right lobe for 25 patients(50%), in the left lobe for 15 patients(30%), in the both lobes for 4 patients(8%), and in the caudal lobe for 1 patient(2%), while 5 cases(10%) were not given in the articles. Eleven patients(22%) had the history of malignancy, 15 patients(30%) were concomitant with autoimmune disease, and 5 patients(10%) were concomitant with virus hepatitis infection. Thirty-six patients(72%) were diagnosed as malignancy preoperatively, and 43 patients(86%) underwent surgical resection. ConclusionsRLH of liver is an extremely rare and benign condition which presents a female predilection and often concomitants with autoimmune disease and history of malignancy. Considering the risk of malignant transformation, surgical resection is recommended and further researches are necessary for better understanding of this disease.
目的:探讨彩色多普勒超声在诊断冠状动脉造影术后引发的医源损伤性假性动脉瘤的临床价值。方法: 经股动脉穿刺,行冠状动脉造影术而发生的股动脉假性动脉瘤共39例,所有患者都采用高频彩色多普勒诊断仪,对动脉瘤的二维超声图像、彩色多普勒图像及脉冲多普勒图像进行分析。结果: 39例假性动脉瘤患者在穿刺部位动脉的一侧均显示一搏动性无回声区或混合性低回声区;彩色多普勒显示无回声区内呈涡流或旋转样血流信号,表现为一半红色一半蓝色;脉冲多普勒显示典型的双期双向频谱。39例假性动脉瘤彩色多普勒超声诊断完全明确。其中32例在彩色多普勒超声监控下行人工加压包扎修复。7例经血管外科手术修补治疗。结论: 彩色多普勒超声在诊断冠状动脉造影术后造成的医源损伤性假性动脉瘤,在观察动脉瘤的大小、形态、瘤体的结构,判断来源动脉破口定位上准确、简便、无创,且可在超声引导下行安全无创治疗,可作为该病诊断及治疗的首选方法。
Objective To evaluate surgical treatment of infected femoral artery pseudoaneurysm. Methods The data on surgical treatment of 45 patients with infected femoral artery pseudoaneurysm admitted from January 2003 to June 2008 were analyzed retrospectively. Fourty-three patients underwent operative treatment including excision of infected femoral artery pseudoaneurysm, exhaustive debridement and bypass graft with vascular prosthesis. Two patients were unavoidable to undergo removing of infected femoral artery pseudoaneurysm and ligating the proximal and distal artery of pseudoaneurysm because of severe infection and large volume. Results The patients were followed up from 3 to 12 months (mean 7.82 months). The limbs of all the patients underwent bypass graft with vascular prosthesis were salvaged successfully, patients of which had secondary wound healing and had not intermittent lameness. One of two patients performed ligation of artery was salvaged successfully but had severe intermittent lameness, another patient underwent high amputation above knee because of ischemic gangrene. Conclusion For infected femoral artery pseudoaneurysm, the operative treatment including excision of infected femoral artery pseudoaneurysm, exhaustive debridement and bypass graft with vascular prosthesis is effective and safe.
Objective To discuss the clinical application value of CT angiography (CTA) in traumatic pelvic artery pseudoaneurysm and dissecting aneurysm. Methods A total of 8 patients including 7 with traumatic pelvic artery pseudoaneurysm and 1 with dissecting aneurysm diagnosed by CTA in Suining Central Hospital from August 2012 to January 2016 were enrolled in this study, in whom 6 patients with traumatic pseudoaneurysm treated with embolotherapy were confirmed by digital subtraction angiography. Image post-processing techniques of CTA including curve planar reformation, multiplanar reconstruction and volume rendering were used. Results In the seven patients diagnosed as solitary traumatic pelvic artery pseudoaneurysm by CTA, 3 had superior gluteal artery pseudoaneurysm, 2 had inferior gluteal artery pseudoaneurysm, and 2 had external iliac artery pseudoaneurysm. The 7 pseudoaneurysms were pouch-shaped with the short diameters ranged from 9 to 64 mm and the long diameters ranged from 11 to 78 mm. Six locations of artery laceration were displayed clearly, thereinto 1 case was combined with arteriovenous fistula. In addition, a vessel occlusion caused by the limitation of right external iliac artery dissecting aneurysm and the thrombosis in left side of the external iliac artery was found in 1 case. Conclusions As a non-invasive diagnostic technique, CTA can accurately diagnose traumatic pelvic artery pseudoaneurysm and dissecting aneurysm, clearly display the location relationship of pseudoaneurysm and its parent artery, and find whether arteriovenous fistula exists. Beyond that, the true and false lumen of dissecting aneurysm can be precisely identified by this technique. CTA can provide important image information for formulating individual treatment plan.
ObjectiveTo review the definition, incidence, risk factors, potential pathogenesis, biomarkers, and choice of follow-up treatment strategies of hyperprogressive disease (HPD).MethodDomestic and international literatures were collected to summarize the research progress of HPD in patients with malignant tumors who treated with immune checkpoint inhibitors (ICIs).ResultsThe research types of HPD were scattered, the sample size was limited, the definition standard was different, and there was lack of prospective validation studies. Therefore, the early warning assessment and molecular mechanism of HPD would become the next focus of the study of immunotherapy.ConclusionICIs can greatly improve the survival time of some patients with advanced malignant tumor, although some patients have HPD during treatment, but the incidence is relatively low.
