ObjectiveTo investigate the diagnosis and treatment of pancreatic cystic neoplasm. MethodsThe clinical data of 40 cases of pancreatic cystic neoplasm from October 2001 to October 2013 in our hospital were retrospec-tively analyzed. ResultsPatients with pancreatic cystic neoplasm had no specific clinical feature. Ultrasonography and computed tomography displayed a cystic tumor in 57.5%(23/40) and 72.5%(29/40) of all patients, respectively, but could not distinguish the histological types. All of the patients had been operated, among them 2 cases were misdia-gnosed as pseudocysts and internal drainage; another 38 patients were undergoing the distal pancreatectomy. Pathologic examination results after operation showed 23 cases of serous cystadenoma, 9 cases of mucinous cystadenoma, 3 cases of intraductal papillary mucinous adenoma, and 5 cases of mutinous cystadenocarcinoma. Thirty five patients were followed-up. The followed-up time range from 2 months to 8 years, verage(74.2±12.8) months. Among the 3 patients with mucinous cystadenocarcinoma, 1 patient alived with no evidence of recurrence, the other 2 patients died of tumor invasion and metastasis in 4 months and 7months after operation. The others were still alive now with no evidence of recurrence. ConclusionSurgical resection is the most effective treatment for pancreatic cystic tumor, even if the patients with no any symptoms.
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.
Objective To summarize ultrasonography, CT and (or) MRI imaging features of cystic liver lesions so as to improve its diagnostic accuracy. Methods The literatures relevant imaging studies of different types of cystic liver lesions at home and abroad were searched. Then with the etiology as clue, the imaging fetures of ultrasonography, CT and (or) MRI plain scan and enhancement scan were summarized. Results The cystic liver lesions had many types, their imaging findings were different and existed overlaps. The diagnosis and differential diagnosis of atypical cases were difficult. ① For the simple hepatic cyst, it was a round cystic mass with water-like echo, density and signal. The boundary was clear, and there was no separation in the cyst, without contrast enhancement. The sensitivity and specificity of diagnosing were higher by ultrasonography and MRI as compared with CT. ② For the bile duct hamartoma and Caroli diease, they were manifested as multiple cysts, widely distributed in the whole liver, without enhancement for the most lesions. The multiple cystic lesions without communicating with the bile duct was the key sign of differential diagnosis for these two dieases. ③ Enhancing mural nodules were more common in cystadenocarcinoma than cystadenoma. The accurate diagnosis of biliary cystadenoma depended on combination of ultrasonography, CT, and MRI findings. ④ For the cystic liver metastatic tumor, it was multiple cystic neoplasms in the liver parenchyma or around the liver. CT was the main method for the diagnosis, and which showed that the density was lower than that of the liver parenchyma, peripheral ring-enhanced lesion as enhanced scan. It was easy to distinguish with simple hepatic cyst by MRI. ⑤ For the cystic hepatocellular carcinoma, it presented as a multilocular cystic solid tumor. The presence of tumor thrombus in portal vein could help to the diagnosis. ⑥ For the undifferentiated embryonal sarcoma, CT plain scan showed the cystic low density mass with clear boundary, the edge with calcification, enhanced scan showed that the soft tissue composition presented continuous strengthening sign. There was no specific signal in MRI plain scan, and the periphery of the tumor was slowly strengthening. ⑦ For the liver abscess, it was easy to diagnose because it had different characteristic features in different pathological phase, but it was misdiagnosis of intrahepatic cholangiocarcinoma when its symptoms were atypical. ⑧ The ultrasonography and the CT were the optimal methods for the hepatic cystic echinococcosis and the hepatic alveolar echinococcosis respectively. The significances of imaging were to determine the activity of hydatid cyst and to identify anatomy structure among alveolar echinococcosis, bile duct and blood vessel, and judge invasion or not, MRCP was important for diagnosis. Conclusions Abdominal ultrasonography could be used as the first choice for diagnosis of cystic liver lesions, CT and MRI could be used as effective supplementary methods for it. A combination of various imaging techniques is key to diagnosis. Moreover, number and morphology of lesion, and solid component or not are important imaging features of diagnosis and differential diagnosis of cystic liver lesion.
Objective To summarize the current progress in diagnosis and treatment of polycystic liver disease, and provide ideas for further research direction and clinical practice of polycystic liver disease. Method The domestic and foreign literature about polycystic liver disease was reviewed, screened, and summarized. Results The diagnosis, evaluation, and classification of polycystic liver disease were mainly performed clinically by abdominal ultrasound and CT. Surgical treatment was the main treatment, including aspiration sclerotherapy, fenestration, segmental hepatectomy, and liver transplantation. Conclusions The classification and evaluation scheme of polycystic liver disease needs to be improved, and its medical treatment still needs further research. Estrogen receptor and gonadotropin-releasing hormone receptor are promising therapeutic targets.
目的 评价不同外科手术治疗肝脏囊性占位的临床疗效以及不同外科治疗策略的优缺点。 方法 对1998年1月－2011年12月收治的肝囊性占位患者的临床资料进行回顾性分析。共纳入148例患者，其中单纯性肝囊肿患者86例（单发35例，多发51例），多囊肝病患者62例。43.9%（65/148）患者行腹腔镜囊肿开窗治疗，27.0%（40/148）患者行开腹囊肿开窗术，21.6%（32/148）的患者行经皮囊肿穿刺及硬化剂注入术，另有7.4%（11/148）患者行开腹肝部分切除联合囊肿开窗术。 结果 经过手术治疗后，患者症状缓解率高达100.0%；术中患者出血量以经皮囊肿穿刺及硬化剂注入术最少，而以开腹肝部分切除联合囊肿开窗术最多。对于单纯性肝囊肿单发患者，不同手术治疗后均未出现症状复发；对于单纯性肝囊肿多发患者，肝部分切除联合囊肿开窗术治疗未出现症状复发，而经皮囊肿穿刺及硬化剂注入、腹腔镜囊肿开窗和开腹囊肿开窗治疗则分别有3、4、2例患者发生症状或影像学复发，总复发率为17.6%(9/51)；对于多囊肝病患者，经皮囊肿穿刺及硬化剂注入、腹腔镜囊肿开窗、开腹开窗和肝部分切除联合囊肿开窗治疗则分别有2、7、3和2例患者发生症状或影像学复发，总复发率为22.6%（14/62）。 结论 目前常用治疗方式对于单纯性肝囊肿单发患者疗效均理想，但对于单纯性多发肝囊肿和多囊肝病患者远期效果均尚不理想。
ObjectiveTo summarize the experience of diagnosis and treatment of pancreatic cystic neoplasms (PCN).MethodThe general information, imaging findings, preoperative blood biochemical indexes, tumor markers, operation related data, postoperative complications, and pathological results of patients with PCN confirmed by pathological examination in Affiliated Hospital of Xuzhou Medical University from January 1, 2014 to December 31, 2019 were retrospectively analyzed.ResultsAmong the 158 patients who underwent surgical resection, the male to female ratio was 1∶1.6, and the median age was 56.2 years (range 26 to 82 years). Serous cystadenoma (SCN) was the most common, accounting for 34.2% (n=54), followed by mucinous cystadenoma (MCN) and intraductal papillary mucinous neoplasm (IPMN), accounting for 26.6% (n=42) and 20.2% (n=32). The proportion of solid pseudopapillary tumor (SPT) was the smallest, which was 19.0% (n=30). The PCN malignant rate was 19.0% (n=30), with the highest malignant rate being IPMN (43.8%, n=14), and the lowest being SCN (3.7%, n=2). Patients with PCN malignant group had significantly higher serum CA19-9, CEA, CA125, and neutrophil/lymphocyte ratio (NLR) than those in the benign group（all P<0.05）. The preoperative diagnosis of PCN was ambiguous, and the rate of misdiagnosis was high. The correct diagnosis rate of accurate preoperative specific classification was only 31.6% (n=50), and the lowest SCN (14.8%, n=8). High CA19-9, high NLR value, tumor location in the head/neck of pancreas and enhanced solid component were independent predictors of malignant PCN (P<0.05).ConclusionImproving the preoperative diagnosis ability of PCN and accurately determining the PCN classification before operation are helpful for the standardized treatment of PCN.
ObjectiveTo explore the diagnostic value of exhaled volatile organic compounds (VOCs) for cystic fibrosis (CF). MethodsA systematic search was conducted in PubMed, EMbase, Web of Science, Cochrane Library, CNKI, Wanfang, VIP, and SinoMed databases up to August 7, 2024. Studies that met the inclusion criteria were selected for data extraction and quality assessment. The quality of included studies was assessed by the Newcastle-Ottawa Scale (NOS), and the risk of bias and applicability of included prediction model studies were assessed by the prediction model risk of bias assessment tool (PROBAST). ResultsA total of 10 studies were included, among which 5 studies only identified specific exhaled VOCs in CF patients, and another 5 developed 7 CF risk prediction models based on the identification of VOCs in CF. The included studies reported a total of 75 exhaled VOCs, most of which belonged to the categories of acylcarnitines, aldehydes, acids, and esters. Most models (n=6, 85.7%) only included exhaled VOCs as predictive factors, and only one model included factors other than VOCs, including forced expiratory flow at 75% of forced vital capacity (FEF75) and modified Medical Research Council scale for the assessment of dyspnea (mMRC). The accuracy of the models ranged from 77% to 100%, and the area under the receiver operating characteristic curve ranged from 0.771 to 0.988. None of the included studies provided information on the calibration of the models. The results of the Prediction Model Risk of Bias Assessment Tool (PROBAST) showed that the overall bias risk of all predictive model studies was high, and the overall applicability was unclear. ConclusionThe exhaled VOCs reported in the included studies showed significant heterogeneity, and more research is needed to explore specific compounds for CF. In addition, risk prediction models based on exhaled VOCs have certain value in the diagnosis of CF, but the overall bias risk is relatively high and needs further optimization from aspects such as model construction and validation.
