Intrahepatic cholangiocarcinoma as a rare secondary malignancy after allogeneic hematopoietic stem cell transplantation for childhood acute lymphoblastic leukemia: A case report

Secondary malignancies are a significant cause of non‐relapse mortality in patients who undergo allogeneic HCT. However, secondary liver cancer is rare, and ICC following HCT has never been reported in the literature. Secondary solid cancers typically have a long latency period, and cholangiocarcinoma is classically a malignancy occurring in older individuals. Here, we report the first case of secondary ICC, which presented just 3 years after HCT in a young adult with a history of childhood ALL. A 26‐year‐old male with history of precursor B‐cell ALL presented with asymptomatic elevated liver function tests 3 years after HCT. Laboratories were indicative of biliary obstruction. ERCP showed focal biliary stricturing of the common and left hepatic ducts. MRCP revealed left intrahepatic duct dilatation, suggestive of intrahepatic obstructing mass. Additional workup lead to a clinical diagnosis of ICC. The patient underwent left hepatectomy with extrahepatic bile duct resection and portal lymphadenectomy. Surgical pathology was consistent with moderately differentiated cholangiocarcinoma. Our case illustrates a rare SMN following HCT for ALL. It is the first case report of ICC occurring as a secondary cancer in this patient population. Although cholangiocarcinoma is characteristically diagnosed in the older population, it must remain on the differential for biliary obstruction in post‐HCT patients.     

PICC导管继发性异位并打结1例的护理体会

经外周置入的中心静脉导管(peripherally inserted central catheter,PICC)具有留置时间长、安全可靠、成功率高等优点,在临床上被广泛用于长期连续输液治疗、肠外营养及恶性肿瘤的静脉化疗给药。静脉化疗对血管损伤及局部刺激很大,PICC导管可以减少患者反复穿刺的痛苦及对血管的伤害,恶性肿瘤患者尤为适用[1]。但在PICC导管的留置以及维护期间也会有相关并发症的出现,其中就包括导管继发性异位。     

腹腔镜肝切除术中副损伤预防及处理

随着腹腔镜肝切除术在国内开展，腹腔镜肝切除术的手术适应证和手术范围在逐渐扩大，外科医生在手术操作过程中的意外和手术风险也逐渐提高。腹腔镜肝切除术中副损伤主要包括胆管损伤、术中出血、膈肌损伤、气体栓塞等。当在术中发生意外损伤时，应立即正确辨别出损伤类型，并迅速采取对应的处理策略，及时处理损伤，避免造成更严重的后果。同时，在术中合理使用吲哚菁绿（ICG）荧光染色及实时超声等辅助技术，可减少术中副损伤的发生。     

深部热疗配合输卵管通水术治疗继发性不孕症的疗效研究

目的:探析对继发性不孕症患者行以深部热疗配合输卵管通水术治疗的疗效。方法:于2018年1月~2019年1月择取某院收治的40例继发性不孕症患者,按照数字奇偶法将其分成对照组和研究组,对照组20例患者予以输卵管通水术治疗,研究组20例患者予以输卵管通水术配合深部热疗治疗,对照分析两组临床效果。结果:从临床总有效率上来看,研究组高于对照组(P<0.05);治疗前两组TNF-α、IL-6对比无统计学差异,治疗后研究组TNF-α、IL-6均优于对照组(P<0.05)。结论:对继发性不孕症患者来说,深部热疗配合输卵管通水术治疗的效果显著。     

超声引导下经皮经肝胆囊穿刺后继发性脓肿发生的危险因素分析

目的 探讨超声引导下经皮经肝胆囊穿刺置管引流术(Percutaneous Transhepatic Gallbladder Drainage,PTGD)术后发生继发性脓肿(Secondary abscess,SA)的发生率及其危险因素。方法 回顾性分析南京医科大学附属无锡人民医院2010年1月至2017年12月间410例经超声引导下PTGD患者的临床资料,采用单因素和多因素Logistic回归分析相关危险因素。结果 12例(2.93%,12/410)患者PTGD术后出现SA,再次针对SA穿刺引流的成功率100%。对良性疾病梗阻、基础疾病、胆囊大小、腹水、凝血功能、血小板、糖化血红蛋白(HbA_1C)、短期内引流管脱落/自行拔出等混杂因素进行校正后,Logistic回归分析表明短期内引流管脱落/自行拔出(OR=6.64,95%Cl：3.34～13.81,P=0.03)和HbA_1C＞9.0%(OR=3.38,95%Cl：1.22～7.95,P=0.04)是引起术后SA的独立危险因素。结论 SA是超声引导下PTGD术后罕见的并发症,再次穿刺引流是治疗SA有效和安全的方法。临床可通过加强对穿刺引流管的保护和应用降血糖药物,降低PTGD术后SA的发生。     

A case-control study of risk factors for intussusception among infants in eastern France after the introduction of the rotavirus vaccine

ObjectiveThe objective of the present study was to investigate the risk factors for intussusception (IS) among infants, including vaccination against rotavirus.MethodsCase-control study with systematic inclusion of all infants aged <1 year with suspected IS admitted to emergency departments in the eastern region of France between 1 April 2008 and 31 March 2012. All cases classed level 1 according to the Brighton classification were matched to 4 hospital controls. Two exposure windows were examined; exposure to the first dose of rotavirus vaccine in the 7 and in the 14 days prior to the occurrence of IS.ResultsA total of 115 cases were matched with 457 controls. The average vaccination coverage rate over the 4 years of study was 8.6%. Rotavirus vaccine was not found to be significantly associated with the occurrence of IS in the 7 days (odds ratio (OR) not calculated; p = 0.99) and in the 14 days after administration of one dose vaccine (OR 1.33, 95% confidence interval (CI) 0.14–12.82). Infant formula alone or combined with breastfeeding was associated with an excess risk of IS (OR 2.74, 95% CI 1.10–6.79). A history of gastroenteritis within 2 weeks prior to hospitalisation was also associated with an increased risk (OR 2.24, 95% CI 1.07–4.67).ConclusionOur study indicates that infant formula alone or combined with breastfeeding is a risk factor for IS. A small, non-significant increase in the risk of IS was observed after rotavirus vaccination, although the low vaccine coverage rate likely precluded detection of a significant increase in risk.
