目的 探讨小儿结肠系膜淋巴管瘤的诊断与治疗方法。方法 回顾性分析我院2006年1月至2011年12月期间手术治疗的5例小儿结肠系膜淋巴管瘤的临床资料。结果 3例诊断为腹腔包块性质待查的患儿，术中发现腹腔肿块来源于乙状结肠系膜，其中1例肿块侵犯到降结肠系膜达结肠脾曲而行左半结肠切除＋肠吻合术，另外2例行乙状结肠系膜淋巴管瘤切除＋部分乙状结肠切除＋肠吻合术；1例患儿诊断为急性化脓性阑尾炎合并乙状结肠系膜淋巴管瘤，行阑尾切除＋乙状结肠系膜淋巴管瘤切除＋肠吻合术，1例患儿诊断为乙状结肠系膜淋巴管瘤破裂并弥漫性腹膜炎，行乙状结肠系膜淋巴管瘤切除＋乙状结肠造瘘术，术后6个月后再行二期手术。5例患儿手术后恢复良好，未发生吻合口漏等并发症。术后随访5个月～5年， （2.3±1.1）年，1例失访，余均存活，仍在随访中，所有病例均未复发。结论 日常行阑尾手术中，应常规探查小肠、结肠；未进行肠道准备的结肠一期吻合手术中结肠灌洗可减少吻合口漏等并发症的发生率；腹腔感染严重的患儿结肠一期吻合不可取，结肠造瘘安全；小儿结肠系膜淋巴管瘤术前确诊困难，反复出现腹痛、腹部包块的患儿应想到结肠系膜淋巴管瘤的可能性，行充分的肠道准备后择期手术，手术是肠系膜淋巴管瘤唯一的治疗方法。
目的:探讨纤维支气管镜(简称纤支镜)肺泡灌洗术在治疗肺部感染性疾病的疗效。方法:共从内科系统中入选社区获得性肺炎和医院获得性肺炎患者122例,将其分为二组,治疗组:传统治疗加纤支镜肺泡灌洗术治疗肺部感染,共52例;对照组:传统方法治疗肺部感染,共70例。结果:两组病例在发热时间,咳嗽,咳痰及肺部罗音消失时间,住院日,抗生素使用时间,治愈率和死亡率方面对比均有显著性差异(Plt;0.05)。结论:纤支镜肺泡灌洗术在治疗肺部感染性疾病的疗效确切,且术中危险性小,值得推广。
Objective To analyze the risk factors inducing tumor cells exfoliating during radical resection of rectal cancer. Methods Sixty patients who were diagnosed as rectal cancer from May 2006 to November 2007 and given radical operations were assigned prospectively in this study. Before cutting the rectal stump below the tumor, saline was instilled into rectum to irrigate the stump. Collected irrigating fluids were sent to pathology laboratory, and the exfoliated malignant cells were tested by HE （haematoxylin and eosin） dyeing and common smear technique. The results of examines were collected and statistical analysis, including a Logistic regression model, was performed. Results Exfoliated malignant cells were found in 27 samples. By univariate analysis, the statistically significant factors defining a high risk of exfoliating were age, tumor size, TNM stage, operation time and operation method (Plt;0.05). Only TNM stage， operation time and operation method were confirmed by Logistic regression analysis to independently result in a statistically significant increased risk of exfoliating. Conclusion Irrigating the rectal stump before cutting down the tumor is essential to avoid local recurrence. The effects of TNM stage, tumor size and operation time are important. Although the laparoscopic surgery is more predominant than conventional surgery for non-neoplasma technology, irrigating is an important process.
ObjectiveTo assess the methodological quality of guidelines for bronchoscopic alveolar lavage. MethodsCNKI, VIP, WanFang Data, CBM, Web of Science, PubMed, EMbase databases and medlive.cn, the National Guideline Clearinghouse (NGC), the National Guideline International Network (GIN), the Scottish Intercollegiate Guidelines Network (SIGN), the National Institute for Clinical Excellence (NICE), and the World Health Organization (WHO) websites were electronically searched to collect guidelines of bronchoscopic alveolar lavage from inception to December 2020. Two reviewers independently screened literature, extracted data, and assessed the methodological quality of the guidelines by using AGREE Ⅱ tool. ResultsA total of 19 guidelines were included, with 5 from China, 5 from the USA, 3 from Europe, 2 from the UK, 1 from Australia, 1 from Israel, 1 from Spain, and 1 from India. The average standard score rates of the 19 guidelines in the six fields were 50.73% for scope and purpose, 20.02% for participants, 15.13% for formulation rigor, 36.40% for clarity of presentation, 3.51% for applicability, and 22.37% for editorial independence.ConclusionsThe quality of bronchoalveolar lavage guidelines remains relatively low.
Objective To assess the value of procalcitonin ( PCT) in serum and percentage of infected cells ( PIC) in bronchoalveolar lavage fluid ( BALF) for the diagnosis of early ventilator-associatedpneumonia ( VAP) .Methods A prospective observational study was conducted in a teaching hospital. The patients consecutively admitted to the intensive care unit from January 2011 to June 2012, who received mechanical ventilation for more than 48h and clinically suspected for VAP, were recruited in the study.Patients with infection outside the lungs and previous diagnosed infection were excluded. PCT was detected and bronchoalveolar lavage was performed in the day when VAP was diagnosed. BALF cells were stained by May-Grunwald Giemsa ( MGG) for counting 100 phagocytic cells and calculating infected cells ( ICs )percentage.Results 76 of all 421 patients were enrolled in this study, 64 of which were diagnosed, 12 were under-diagnosed. The PCT [ ( 3. 48 ±1. 46) ng/mL vs. ( 1. 53 ±0. 60) ng/mL] and PIC [ ( 3. 11 ±1. 47) % vs. ( 1. 08 ±0. 29) % ] were significant higher in the patients with VAP. The threshold of 2 ng/mL of PCT and 2% of PIC corresponded to sensitivity of 78. 12% and 78. 12% , and specificity of 75. 00% and 91. 67% , respectively. The area under the receiver operating characteristic ( ROC) curve was 0. 87 ( 95% CI 78. 9%-95. 9% ) and 0. 874 ( 95% CI 79. 2% -94. 9% ) , respectively. The area under ROC curve was 0. 979, and the sensitivity was 97. 36% , specificity was 97. 36% when the two cutoff values were both achieved. Conclusion PCT and PIC are useful markers to diagnose early VAP quickly and conveniently and allow early antibiotic treatment of patients with suspected VAP.
ObjectiveTo investigate the clinical features of patients who went through Nocardia co-infection with Aspergillus in lung.MethodsClinical data of 3 pulmonary nocardiosis patients complicated with aspergillosis from China-Japan Hospital during June 2015 and May 2016 were retrospectively analyzed. Nine related literatures found at PubMed were reviewed and they all were case report. No Chinese literature was found at Wanfang data and Chinese Journal Fulltext Database.ResultsAll of the 3 patients were diagnosed as pulmonary nocardiosis by etiological detection, at the same time meeting the diagnostic criteria of invasive pulmonary aspergillosis. Two cases were infected with Aspergillus fumigatus. Aspergillus was not detected in the third case, but the galactomannan of serum and bronchoalveolar lavage fluid significantly increased.ConclusionPulmonary nocardiosis complicated with aspergillosis trends to occur in immunocompromised patients, and pathogen detection is important for diagnosis.
