肝癌肝切除术后感染并发症相关危险因素分析

目的 探讨肝癌肝切除术后感染并发症相关危险因素.方法 对本院近6年来行肝切除术的217例肝癌患者的临床资料进行回顾性分析,对可能引起感染并发症的因素进行统计学分析.结果 217例肝癌肝切除病例根据术后是否发生感染并发症分为感染组（n=33）与非感染组（n=184）.33例中,手术部位感染15例（占45.45％）、肝脏周围感染4例（占12.12％）、远处部位感染14例（占42.42％）;术后死亡3例（占1.38％）.多因素Logistic逐步回归分析显示年龄（P=0.006,0R=2.564）、糖尿病史（P=0.02,OR=1.996）、手术时间（F=0.005,0R=2.237）及胆漏发生率（P＜0.001,0R=7.325）是肝切除术后感染并发症的独立危险因素.结论 年龄、糖尿病史、手术时间及胆漏发生率是影响肝癌患者肝切除术后感染并发症发生的独立危险因素.     

肝切除术后肝功能衰竭的危险因素

随着肝脏外科技术的发展,围手术期管理和患者筛选标准的进步使可以接受半肝切除术或扩大肝切除术的患者数量大大增加.而肝切除术后肝功能衰竭是肝切除术后严重的并发症之一,肝切除术后肝功能衰竭患者相关风险中糖尿病及已有肝脏疾病如肝硬化、脂肪肝、胆汁淤积等是最重要的危险因素.手术相关风险中残肝体积及术中大出血是影响肝切除术后肝功能衰竭发病率及病死率的关键因素.而到目前为止还没有很好的方法治疗肝功能衰竭,所以预防显得尤为重要.     

腹腔镜胆囊切除术对患者肝功能及C反应蛋白水平的影响

目的：探讨腹腔镜胆囊切除术（laparoscopic cholecystectomy,LC）与开腹胆囊切除术（open cholecystectomy,OC）两种术式对患者肝功能的影响。方法：随机将慢性胆囊炎合并胆囊结石患者75例分为LC组40例,OC组35例,分别于术前及术后第1、3、5天抽取外周静脉血2ml,检测以下指标：血清总胆汁酸（TBA）、丙氨酸氨基转移酶（ALT）、天冬氨酸氨基转移酶（AST）、血清总胆红素（TBIL）、γ-谷氨酸转肽酶（γ-GT）、碱性磷酸酶（ALP）以及C反应蛋白（CRP）。结果：LC组和OC组手术后第1天与第3天TBA、ALT、AST、TBIL及CRP均升高,LC组的CRP升高较OC组更加显著（P〈0.05）。手术后第5天两组各项指标均恢复至正常水平,两组无显著差异。结论：腹腔镜胆囊切除术与开腹胆囊切除术相比,对肝功能的影响无明显差异,实施腹腔镜胆囊切除术安全可行。

Increase of C-reactive protein serum values following haemodialysis

In this study serum C-reactive protein values were measured to prove the induction of an acute-phase response during the haemodialysis procedure in end-stage renal disease patients. C-reactive protein values were measured with a sensitive enzyme-linked immunosorbent assay to detect values below the detection limit of standard assays. Predialysis C-reactive protein serum values in 17 patients on regular haemodialysis with cuprophan dialysers were greater than those of 18 normal controls (P less than 0.001). In the same group of haemodialysis patients serum C-reactive protein values 24 h after haemodialysis were significantly greater than predialysis values (P less than 0.001). These results suggest that acute-phase proteins are induced during haemodialysis, probably due to cytokine release during the haemodialysis procedure.

目的:分析影响早期肝癌术后复发的危险因素。方法:回顾性分析2002年1月至2004年12月手术切除并获得随访的197例经组织学确认为早期肝癌(单发,≤5 cm,无淋巴结及远处转移,无门静脉癌栓)病人,利用K-M生存曲线分析来评估不同组病人的复发差异,采用COX比例风险回归模型来研究与早期肝癌复发相关的危险因素。结果:197例病人中,肿瘤的中位直径为2.8 cm,肿瘤直径>2 cm的病人占58.4%,病人血清AFP阳性(>100 ng/mL)占47.7%,病理结果提示有微血管癌栓(MVI)者为32.5%。术后中位复发时间(TTR)为28.5个月,总体复发率为59.4%。术后1、3、5年的累积复发率分别为26.4%、55.6%、66.0%。我们建立了一个包含3组的早期肝癌复发评估系统,组中位TTR和1、3、5年复发率分别为:0分组(40.9个月和9.9%、26.7%、41.7%)、1分组(31.1个月和14.1%、50.1%、63.0%)、2～3分组(18.9个月和48%、71.8%、89.1%)(P<0.001)。结论:肿瘤大小、AFP水平和MVI是早期肝癌术后复发的独立危险因素。在不同危险因素存在的情况下,早期肝癌病人的复发时间差异明显。     

Incidence,risk factors and consequences of bile leakage following laparoscopic major hepatectomy

Background

Bile leakage (BL) remains a common cause of major morbidity after open major liver resection but has only been poorly described in patients undergoing laparoscopic major hepatectomy (LMH). The present study aimed to determine the incidence, risk factors and consequences of BL following LMH.

Methods

All 223 patients undergoing LMH between 2000 and 2013 at two tertiary referral centres were retrospectively analysed. BL was defined according to the International Study Group of Liver Surgery, and its incidence and consequences were assessed. Risk factors for BL were determined on multivariate analysis.

Results

BL occurred in 30 (13.5 %) patients, and its incidence remained stable over time (p = 0.200). BL was diagnosed following the presence of bile into the abdominal drain in 14 (46.7 %) patients and after drainage of symptomatic abdominal collections in 16 (53.3 %) patients without intra-operative drain placement. Grade A, B and C BL occurred in 3 (10.0 %), 23 (76.6 %) and 4 (13.4 %) cases, respectively. Interventional procedures for BL included endoscopic retrograde cholangiography, percutaneous and surgical drainage in 10 (33.3 %), 23 (76.7 %) and 4 (13.3 %) patients, respectively. BL was associated with significantly increased rates of symptomatic pleural effusion (30.0 vs. 11.4 %, p = 0.006), multiorgan failure (13.3 vs. 3.6 %, p = 0.022), postoperative death (10.0 vs. 1.6 %, p = 0.008) and prolonged hospital stay (18 vs. 8 days, p < 0.001). On multivariable analysis, BMI > 28 kg/m² (OR 2.439, 95 % CI 1.878–2.771, p = 0.036), history of hepatectomy (OR 1.675, 95 % CI 1.256–2.035, p = 0.044) and biliary reconstruction (OR 1.975, 95 % CI 1.452–2.371, p = 0.039) were significantly associated with increased risk of BL.

Conclusions and relevance

After LMH, BL occurred in 13.5 % of the patients and was associated with significant morbidity. Patients with one or several risk factors for BL should benefit intra-operative drain placement.

     

Microalbuminuria post-renal transplantation: relation to cardiovascular risk factors and C-reactive protein

Abstract:  Microalbuminuria predicts graft loss and all-cause mortality in renal transplant recipients. In the general population, it clusters with both traditional cardiovascular risk factors and elevated C-reactive protein (CRP). Our objective was to define the relationship between microalbuminuria and these risk factors in stable renal transplant recipients. We identified 222 stable recipients who were minimum two months post-transplant and provided three urine albumin-to-creatinine ratio (ACR) measurements, excluding those with recent illness and proteinuria. Microalbuminuria was defined as averaged ACR ≥ 2.0 in men and 2.8 mg/mmol in women (Canadian Diabetes Association 2003). Risk factors associated with microalbuminuria were determined by multivariate logistic regression analysis. Averaged ACR correlated to CRP (R = 0.21, p = 0.001). Prevalence of microalbuminuria was 48% (108/222). Patients with microalbuminuria had higher CRP (7.01 ± 8 vs. 3.21 ± 3 mg/L, p < 0.0001) and systolic BP (129 ± 17 vs. 123 ± 12 mmHg, p = 0.004). Microalbuminuria was associated with increasing CRP [odds ratio 1.129 per 1 mg/L (95% CI 1.058–1.204), p = 0.0002], SBP [1.248 per 10 mmHg (1.023–1.522), p = 0.029] and smoking [1.938 (1.023–3.672), p = 0.042]. Post-transplant microalbuminuria is prevalent and is associated with elevated CRP, elevated BP, and smoking. Its relationship to these factors suggests it may be an indicator of graft and patient health.     

肝切除术后胆汁漏的影响因素分析

背景与目的：胆汁漏是肝切除术后常见的并发症,可导致住院时间的延长及腹腔引流管拔管时间的延后,增加患者的痛苦及治疗费用,严重的胆汁漏会导致腹腔感染及败血症,甚至导致死亡。本研究通过回顾性分析探讨术后胆汁漏发生的相关影响因素,以期为临床减少术后胆汁漏的发生提供参考。方法：回顾性收集中南大学湘雅医院从2020年1月1日—2022年10月1日期间行肝切除术的2 047例患者的基本信息和临床资料。用单因素与多因素Logistic分析法分析术后胆汁漏的影响因素。结果：共纳入1 845例接受肝切除术的患者,其中59例(3.2%)发生胆汁漏,包括A级36例、B级20例、 C级3例。单因素分析显示,既往肝脏手术史(χ²=9.337, P=0.002)、恶性肿瘤诊断(χ²=10.849,P=0.001)、解剖性肝切除(χ²=8.015,P=0.005)、手术时间(t=4.613,P<0.001)、出血量(t=4.274,P<0.001)、是否输血(χ²=5.129,P=0.024)及术中使用纤维蛋白胶(χ<...     

C-reactive protein response following pediatric orthopaedic surgery

The purpose of this study was to describe the pediatric C-reactive protein (CRP) response following orthopaedic surgery, specifically addressing whether CRP values in children return to normal within 3 weeks as they do in adults. Children undergoing elective orthopaedic procedures had serum CRP values measured before surgery and then on days 3, 7, and 21 after surgery. These intervals were chosen to assess the rise, fall, and return to normal of CRP levels. Twenty-two children were studied. CRP levels on day 3 varied from normal to 22.2 mg/dL (mean 7.3 mg/dL), on day 7 they averaged 2.2 mg/dL, and at 3 weeks all values were normal. None of the patients had postoperative infections. The authors concluded that the CRP rise in children may be more varied than in adults. In children, CRP levels return to normal within 3 weeks after surgery. This information can be useful in identifying postoperative infections in children.     

C-reactive protein levels following standard neurosurgical procedures

Summary ¶Background. The aim of the present study was to establish the magnitude and time-course of C-reactive protein increases following routine neurosurgical procedures in the absence of clinical and laboratory signs of infection. Method. C-reactive protein levels were studied daily following ventriculo-peritoneal shunt implantation, anterior cervical fusion, vestibular schwannoma operation, supratentorial glioma surgery, endovascular intracranial aneurysm treatment and open cerebral aneurysm surgery. Findings. The magnitude of the C-reactive protein increase depended on the extent of surgical trauma and peak-levels were recorded between postoperative day one and four after which the levels tapered off. Interpretation. Increases occurring after the fourth postoperative day are likely to be caused by complications of surgery, e.g. infection.Published online July 23, 2003
