necrotizing enterocolitis

坏死性小肠结肠炎
  • 文章类型: Case Reports
    背景:坏死性小肠结肠炎(NEC)和颅内出血是新生儿期的严重紧急情况。这两者似乎并不相关。然而,我们的报告提示,足月新生儿脑实质出血可能通过脑-肠轴改变肠功能,使患者面临NEC风险.
    方法:我们介绍一例足月新生儿自发性脑实质出血病例,该病例在第15天发生早期NEC。
    结论:可能认为脑实质出血是NEC出现的危险因素。临床医生应高度谨慎的NEC在经历过实质性出血的婴儿。本文首次讨论足月新生儿实质性出血与NEC的关系。
    BACKGROUND: Necrotizing enterocolitis (NEC) and intracranial hemorrhage are severe emergencies in the neonatal period. The two do not appear to be correlated. However, our report suggests that parenchymal brain hemorrhage in full-term newborns may put patients at risk for NEC by altering intestinal function through the brain-gut axis.
    METHODS: We present a case of spontaneous parenchymal cerebral hemorrhage in a full-term newborn who developed early-stage NEC on Day 15.
    CONCLUSIONS: It is possible to consider brain parenchymal hemorrhage as a risk factor for the appearance of NEC. Clinicians should be highly cautious about NEC in infants who have experienced parenchymal hemorrhage. This article is the first to discuss the relationship between parenchymal hemorrhage and NEC in full-term newborns.

    背景:吲哚菁绿荧光血管造影,一种经过验证的非侵入性成像技术,用于评估组织血管化。这里,我们报告了3例接受术中吲哚菁绿荧光血管造影的婴儿患者,这些患者因缺乏弱荧光肠切除而出现术后并发症,并评估了残余肠灌注。
    方法:我们观察了2022年1月至2022年12月接受治疗的患者的临床特征和手术结果。静脉注射吲哚菁绿(0.5mg/kg)。第一位患者是一名29天大的女孩,患有手术坏死性小肠结肠炎,在第一眼和第二眼手术中接受了术中吲哚菁绿荧光血管造影。在第二次手术期间,近端空肠难以诊断以检测血流。第二名患者是一名32天大的男孩,患有手术坏死性小肠结肠炎。保留了患者表现出微弱荧光的部分抗肠系膜粘膜;但是,术后形成血肿。第三位患者是一个30天大的男孩,患有中肠扭转。在肠壁中观察到微弱的荧光,距回盲阀5cm的小肠被保留,但是它形成了一个狭窄,30天后患者接受回盲部切除术。
    结论:通过实施吲哚菁绿荧光血管造影术在婴儿肠道中的弱荧光与未恢复的缺血性病变和术后并发症的高风险相关。
    BACKGROUND: Indocyanine green fluorescence angiography, a validated noninvasive imaging technique, is used to assess tissue vascularization. Here, we report three infant patients who underwent intraoperative indocyanine green fluorescence angiography and suffered from postoperative complications caused by the lack of weak fluorescent intestinal resection and assessed residual intestinal perfusion.
    METHODS: We observed the clinical characteristics and operative findings of patients treated from January 2022 to December 2022. Indocyanine green (0.5 mg/kg) was intravenously injected. The first patient was a 29-day-old girl with surgical necrotizing enterocolitis who underwent intraoperative indocyanine green fluorescence angiography at the first- and second-look operations. The proximal jejunum was difficult to diagnose to detect blood flow during the second-look operation. The second patient was a 32-day-old boy with surgical necrotizing enterocolitis. A part of the antimesenteric mucosa of the patient that exhibited weak fluorescence was preserved; however, it formed postoperative hematomas. The third patient was a 30-day-old boy with midgut volvulus. Weak fluorescence in the intestinal wall was observed 5 cm of the small intestine from the ileocecal valve was preserved, but it formed a stricture, and the patient underwent ileocecal resection after 30 days.
    CONCLUSIONS: Weak fluorescence in the intestine in infants by performing indocyanine green fluorescence angiography is associated with a high risk of non-recovering ischemic lesions and postoperative complications.

    CHPS会严重影响婴儿的生长发育,甚至会导致食管反流引起的误吸。有潜在的危险。CHPS是常见的,而胃壁和门静脉有气体的CHPS很少见。胃壁和门静脉中的气体通常是更严重疾病的关键特征。当CHPS患者在胃壁和门静脉中有气体时,它很容易被误认为是一种严重的疾病。
    一名56天大的婴儿在无胆汁呕吐20天后因吸入性肺炎住院。与呕吐相比,这是最常见的症状,肺炎往往会引起更多的关注。因为肺炎,进行了胸部CT扫描,发现食管壁中大量气体积聚,胃,和门静脉。因此,首先考虑NEC,并保守治疗一周。然而,呕吐仍在继续,CHPS经超声证实。CHPS诊断的延迟是由于对气体积聚迹象的认识不足。由于缺乏经验和缺乏关于CHPS与胃肠道肺炎的知识,医生未能做出早期准确的诊断。病例2是一名29天大的男性,因呕吐而没有胆汁而入院。他接受了超声波检查,入院后胃壁和门静脉有气体。经过详细全面的体检,未发现腹膜炎。迅速排除了NEC等危及生命的紧急疾病。他尽快接受了手术,恢复顺利,没有并发症。
    CHPS可能在胃或食管壁和门静脉中存在气体,这不是手术的禁忌症。
    UNASSIGNED: CHPS dramatically affects infant growth and development and can even cause aspiration resulting from esophageal reflux. There is potential danger. CHPS is common, while CHPS with gas in the stomach wall and portal vein is rare. Gas in the stomach wall and portal vein are often the key features of more serious disease. It can be easily mistaken as a serious disease when patients with CHPS have gas in the stomach wall and portal vein.
    UNASSIGNED: A 56-day-old baby was hospitalized for aspiration pneumonia after vomiting without bile for 20 days. Compared with vomiting, which is the most common symptom, pneumonia tends to attract more attention. Because of pneumonia, a chest CT scan was performed and revealed massive gas accumulation in the walls of the esophagus, stomach, and portal vein. Therefore, NEC was considered first and was treated conservatively for one week. However, the vomiting continued, and CHPS was confirmed by ultrasound. The delay in CHPS diagnosis was due to insufficient recognition of the signs of gas accumulation. Because of inexperience and lack of knowledge about CHPS with gastrointestinal pneumatosis, physicians failed to make an early accurate diagnosis. Case 2 was a 29-day-old male who was admitted to the hospital with vomiting without bile. He was examined by ultrasound, which revealed gas in the stomach wall and portal vein after admission to the hospital. No peritonitis was found after a detailed and comprehensive physical examination. Emergency life-threatening diseases such as NEC were quickly ruled out. He received surgery as soon as possible and had an uneventful recovery with no complications.
    UNASSIGNED: CHPS may present with gas in the gastric or esophageal wall and portal vein, which is not a contraindication to surgery.

    许多研究提出在与坏死性小肠结肠炎(NEC)诊断相关的许多生物标志物中使用粪便钙卫蛋白。这项研究旨在评估粪便钙卫蛋白作为纯母乳喂养的婴儿可疑NEC(阶段1)的早期标志物。
    我们从阿斯旺大学医院新生儿重症监护病房的新生儿中收集了20个粪便样本,这些新生儿被诊断为I期NEC。我们将它们与来自匹配的健康新生儿的20个样本进行了比较。通过酶联免疫吸附法测量粪便钙卫蛋白水平。
    病例组粪便钙卫蛋白水平高于对照组(P<0.001)。此外,粪便钙卫蛋白与C反应蛋白呈正相关(P=0.001)。然而,粪便钙卫蛋白与性别或出生后年龄之间没有相关性。
    NEC阶段新生儿的粪便钙卫蛋白水平增加。虽然不具体,其敏感性提示在可疑NEC的评估中作为潜在的生物标志物发挥作用.
    UNASSIGNED: Numerous studies have proposed using fecal calprotectin among many biomarkers associated with necrotizing enterocolitis (NEC) diagnosis. This study aimed to evaluate fecal calprotectin as an early marker for suspected NEC (stage 1) in infants fed exclusively breast milk.
    UNASSIGNED: We collected 20 stool samples from newborns admitted to the neonatal intensive care unit at Aswan University Hospital diagnosed with stage I NEC. We compared them with 20 samples from matched healthy newborns. Fecal calprotectin level was measured by enzyme-linked immunosorbent assay.
    UNASSIGNED: Fecal calprotectin level was higher in cases than in the control group (P < 0.001). Also, there was a positive correlation between fecal calprotectin and C-reactive protein in the studied cases (P = 0.001). However, there were no correlations between fecal calprotectin and sex or postnatal age.
    UNASSIGNED: Fecal calprotectin levels increase in newborns with stage I NEC. Although not specific, its sensitivity suggests a role as a potential biomarker in the evaluation of suspected NEC.

    急性肠道疾病(AID),包括坏死性小肠结肠炎和自发性肠穿孔,是一组通常存在于早产儿中的病症,并与死亡率和发病率升高有关。这些疾病的危险因素在很大程度上仍然未知。研究的目的是确定孪生与AID发展之间的相关性。
    进行单中心回顾性病例对照研究。我们招募了所有诊断为艾滋病的婴儿,通过解剖病理学证实,2010年至2020年在NICU康复。考虑到结果的稀有性,从新生儿的总体群体中随机选择每个受试者的4个匹配的对照。通过创建有向无环图,使用条件逻辑回归模型和多变量模型计算赔率比(OR)和95%置信区间(CI)(www。dagutty.net)。
    研究人群导致65例病例和260例对照。两组的中位胎龄和平均出生体重(克)相似。这些病例具有较高的新生儿病理频率(定义为至少一个动脉导管未闭,早期或晚期败血症,严重呼吸窘迫)(84.6%vs.51.9%),医学辅助生育(33.8%vs.18.8%)和脑室周围白质软化(10.8%vs.2.7%),和较低的类固醇预防频率(67.7%vs.86.9%)。大约50%的病例需要手术。直接效应的OR值与不使用和重复测量声明的逻辑回归表的OR值不同:从1.14到4.21(p=.019)和从1.16到4.29(p=.016),分别。
    我们的研究表明,孪生可能是AID发展的危险因素。由于观察到的病例数较少,需要对更大的人群进行进一步的研究。
    UNASSIGNED: Acute intestinal diseases (AID), including necrotizing enterocolitis and spontaneous intestinal perforation, are a group of conditions that typically present in preterm infants, and are associated with an elevated mortality and morbidity rate. The risk factors for these diseases remain largely unknown. The aim of the study is to identify the correlation between twinning and the development of AID.
    UNASSIGNED: A single-center retrospective case-control study was conducted. We recruited all infants with a diagnosis of AID, confirmed by anatomopathology, recovered in NICU between 2010 and 2020. Considering the rarity of the outcome, 4 matched controls for each subject were randomly chosen from the overall population of newborns. Odds Ratio (OR) and 95% Confidence Interval (CI) were calculated using a conditional logistic regression model and a multivariate model by the creation of a Directed Acyclic Graph (www.dagitty.net).
    UNASSIGNED: The study population resulted in 65 cases and 260 controls. The two groups present similar median gestational age and mean birthweight in grams. The cases have a higher frequency of neonatal pathology (defined as at least one of patent ductus arteriosus, early or late sepsis, severe respiratory distress) (84.6% vs. 51.9%), medically assisted procreation (33.8% vs. 18.8%) and periventricular leukomalacia (10.8% vs. 2.7%), and a lower frequency of steroids prophylaxis (67.7% vs. 86.9%). About 50% of cases needed surgery. The OR for the direct effect were difference from one using logistic regression booth without and with repeated measures statements: from 1.14 to 4.21 (p = .019) and from 1.16 to 4.29 (p = .016), respectively.
    UNASSIGNED: Our study suggests that twinning may be a risk factor for the development of AID. Due to the small number of cases observed, further studies on larger populations are needed.

    背景:坏死性小肠结肠炎(NEC)仍然是新生儿死亡的主要原因之一。本研究报告了来自法国病例对照前瞻性多中心研究的数据。
    方法:共纳入146例有或没有NEC的早产儿(PNs)。对粪便样品(n=103)进行细菌16SrRNA基因测序。使用特定的培养基分离大肠杆菌,丁酸梭菌,和新生梭菌,和菌株进行表型表征。
    结果:PNs的肠道微生物群以厚壁菌和变形杆菌为主,并鉴定了五种肠型。NEC病例和PN对照之间的微生物群组成相似。然而,观察到乳杆菌属的相对丰度差异,在NEC组中明显更低,而梭状芽孢杆菌III簇的明显更高(p<0.05)。在肠型中,在NEC病例中,几种基因型明显更丰富(p<0.05)。关于围产期因素,发现肠道菌群与剖宫产和抗真菌治疗之间存在统计学关联.在NEC案例和PN控制中,基于培养,尿路致病性大肠杆菌的携带率和毒力基因相当。大肠杆菌之间没有发现相关性,丁酸杆菌,和C.新生马车,β-内酰胺抗性,和抗生素治疗。
    结论:在疾病发作时,我们的数据支持NEC和对照婴儿在属水平上的微生物群失调.此外,它提供了有关细菌抗菌药物敏感性的有价值的信息。
    BACKGROUND: Necrotizing enterocolitis (NEC) is still one of the leading causes of neonatal death. The present study reports the data from a French case-control prospective multicenter study.
    METHODS: A total of 146 preterm neonates (PNs) with or without NEC were included. Bacterial 16S rRNA gene sequencing was performed on stool samples (n = 103). Specific culture media were used to isolate Escherichia coli, Clostridium butyricum, and Clostridium neonatale, and strains were phenotypically characterized.
    RESULTS: The gut microbiota of PNs was dominated by Firmicutes and Proteobacteria, and five enterotypes were identified. The microbiota composition was similar between NEC cases and PN controls. However, differences were observed in the relative abundance of Lactobacillus genus, which was significantly lower in the NEC group, whereas that of the Clostridium cluster III was significantly higher (p < 0.05). Within enterotypes, several phylotypes were significantly more abundant in NEC cases (p < 0.05). Regarding perinatal factors, a statistical association was found between the gut microbiota and cesarean delivery and antifungal therapy. In NEC cases and PN controls, the carriage rates and virulence genes of uropathogenic E. coli were equivalent based on culture. No correlation was found between E. coli, C. butyricum, and C. neonatale carriages, beta-lactam resistance, and antibiotic treatment.
    CONCLUSIONS: At disease onset, our data support a microbiota dysbiosis between NEC and control infants at the genus level. In addition, it provides valuable information on bacterial antimicrobial susceptibility.

    背景:坏死性小肠结肠炎(NEC)是早产儿中最常见的危及生命的胃肠道急症。病理生理学是多因素的,仍然没有完全理解。早期诊断和治疗可以降低死亡率和发病率的风险。我们旨在确定与早产新生儿NEC相关的因素。
    方法:本病例对照研究包括2009年1月1日至2018年12月31日在南希新生儿重症监护病房接受NEC治疗的所有早产儿。对于每种情况,根据三个标准匹配两个对照:胎龄(WG),出生日期,和交付方式。产前,围产期,并分析了NEC之前的产后危险因素。
    结果:共有292名婴儿参与了这项研究,其中113人拥有NEC。NEC新生儿的平均胎龄为29WG,平均出生体重,1340g。只有早发性感染被确定为NEC的重要危险因素(15%vs.感染p<0.04的6.6%,28.3%vs.感染和败血症的16.4%p<0.02,NECvs.controls,分别)。迟发性喂养和初始连续肠内喂养与更严重的NEC的发生显着相关(分别为p<0.02和p=0.03)。
    结论:这项研究的结果与肠道菌群失调是NEC的危险因素相一致。发现早发性感染是一个重要的危险因素。肠内喂养实践也可能与NEC有关。
    BACKGROUND: Necrotizing enterocolitis (NEC) is the most common life-threatening gastrointestinal emergency in prematurity. The pathophysiology is multifactorial and remains incompletely understood. Early diagnosis and treatment could reduce the risk of mortality and morbidity. We aimed to identify factors associated with NEC in preterm newborns.
    METHODS: This case-control study included all preterm newborns presenting with NEC and managed between January 1, 2009 and December 31, 2018 in the neonatal intensive care unit of Nancy. For each case, two controls were matched according to three criteria: gestational age (WG), date of birth, and mode of delivery. Antenatal, peripartum, and postnatal risk factors prior to NEC were analyzed.
    RESULTS: A total of 292 infants were involved in the study, 113 of whom had NEC. Mean gestational age for newborns with NEC was 29 WG, and mean birth weight, 1340 g. Only early-onset infection was identified as a significant risk factor for NEC (15% vs. 6.6% for infection p<0.04, and 28.3% vs. 16.4% p<0.02 for infection and sepsis, NEC vs. controls, respectively). Late-onset feeding and initial continuous enteral feeding were significantly associated with the occurrence of more severe NEC (p<0.02 and p = 0.03, respectively).
    CONCLUSIONS: The results of this study are consistent with intestinal dysbiosis being a risk factor for NEC. Early-onset infection was found to be a significant risk factor. Enteral feeding practice may also be associated with NEC.

    气腹通常是由破裂的中空内脏引起的,因此需要手术干预。这可能有各种病因,包括自发的,坏死性小肠结肠炎(NEC),和阻塞。在这些情况下,自发性肠穿孔(SIP)是一种独特的临床实体,其结果优于NEC相关肠穿孔的新生儿。这里,我们介绍了一个罕见的SIP病例,在生命的前八小时以气腹的形式表现出来,强调区分NEC和SIP的重要性,因为每种情况都有不同的治疗选择和结果考虑因素。
    Pneumoperitoneum is typically caused by breached hollow viscera and necessitates surgical intervention. This may have various etiologies, including spontaneous, necrotizing enterocolitis (NEC), and obstruction. In these cases, spontaneous intestinal perforation (SIP) is a unique clinical entity with a better outcome than newborns with NEC-related intestinal perforation. Here, we present a rare case of SIP manifested in the form of pneumoperitoneum in the first eight hours of life, emphasizing the importance of differentiation between NEC and SIP, as each condition has variable treatment options and outcome considerations.

    多发性骨髓瘤(MM)是一种克隆性浆细胞增殖性疾病,其特征是单克隆副蛋白的异常增加,并可导致特定的终末器官损伤。坏死性小肠结肠炎或肠坏死是由细胞死亡定义的外科紧急情况,因为流向胃肠道的血液减少。我们报告了一例75岁的女性,该女性被诊断患有高粘滞症(HVS)并被送往ED。进一步的检查显示,她有一个新的IgGκMM的诊断,她开始化疗。稍后,她出现呼吸窘迫和腹部扩张,排便频率较低,并咨询了普外科。腹部和骨盆的CT扫描对比显示,发现与肠缺血和梗塞一致。病人立即被送进手术室,剖腹探查术显示肠坏死无法存活。她被转为舒适护理,后来去世了。我们旨在提高医生的认识,将HVS作为MM的可能并发症之一,并及早发现以预防发病率和死亡率。
    Multiple myeloma (MM) is a clonal plasma cell proliferative disorder characterized by the abnormal increase of monoclonal paraprotein and can lead to specific end-organ damage. Necrotizing enterocolitis or bowel necrosis is a surgical emergency defined by cellular death because of reduced blood flow to the gastrointestinal tract. We report a case of a 75-year-old female who was diagnosed with hyperviscosity syndrome (HVS) and was sent to ED. Further workup showed that she had a new diagnosis of IgG kappa MM for which she was started on chemotherapy. Later, she developed respiratory distress and abdomen distention with less frequent bowel movements, and general surgery was consulted. CT scan of the abdomen and pelvis with contrast showed findings consistent with bowel ischemia vs infarction. The patient was immediately taken to the operating room, and exploratory laparotomy showed nonsurvivable bowel necrosis. She was transitioned to comfort care and passed away later. We aim to increase awareness among physicians to include HVS as one of the possible complications of MM and to detect it early to prevent morbidity and mortality.

    坏死性小肠结肠炎(NEC)与早产儿的高发病率和死亡率相关。NEC的早期识别和治疗对于改善结果至关重要。肠神经系统(ENS)不成熟已被认为是NEC病理生理学的关键因素。胃肠动力障碍与ENS不成熟有关,可能是NEC发展的预测因素。在这项病例对照研究中,将早产儿(胎龄(GA)<30周)纳入两个IV级新生儿重症监护病房.基于GA(±3天),在生命的第一个月中患有NEC的婴儿与对照1:3匹配。通过对胎粪首次传代时间(TFPM)的逻辑回归分析NEC发育的几率,中途大便的持续时间,临床NEC发病前72小时的平均每日排便频率(DF结论:在这个队列中,没有发现TFPM之间的关联,胎粪的持续时间,和DF背景:•坏死性小肠结肠炎(NEC)是年轻早产儿的一种危及生命的急性肠道炎性疾病。为了促进早期诊断和治疗,已经研究了NEC的早期临床危险因素。•胃肠道活动中断的迹象,如胃潴留和麻痹性肠梗阻,已建立以支持NEC的诊断。然而,排便模式尚未得到充分研究。
    背景:•NEC前3天的排便模式与相应出生后年龄的胎龄匹配对照没有差异。此外,胎粪的首次通过和胎粪通过的持续时间在病例和对照组之间是相当的。目前,排便模式不能作为NEC的早期预警信号。这些参数是否基于肠坏死的位置而不同,还有待阐明。
    Necrotizing enterocolitis (NEC) is associated with significant morbidity and mortality in preterm infants. Early recognition and treatment of NEC are critical to improving outcomes. Enteric nervous system (ENS) immaturity has been proposed as a key factor in NEC pathophysiology. Gastrointestinal dysmotility is associated with ENS immaturity and may serve as a predictive factor for the development of NEC. In this case-control study, preterm infants (gestational age (GA) < 30 weeks) were included in two level-IV neonatal intensive care units. Infants with NEC in the first month of life were 1:3 matched to controls based on GA (± 3 days). Odds ratios for NEC development were analyzed by logistic regression for time to first passage of meconium (TFPM), duration of meconial stool, and mean daily defecation frequency over the 72 h preceding clinical NEC onset (DF < T0). A total of 39 NEC cases and 117 matched controls (median GA 27 + 4 weeks) were included. Median TFPM was comparable in cases and controls (36 h [IQR 13-65] vs. 30 h [IQR 9-66], p = 0.83). In 21% of both cases and controls, TFPM was ≥ 72 h (p = 0.87). Duration of meconial stool and DF < T0 were comparable in the NEC and control group (median 4 and 3, resp. in both groups). Odds of NEC were not significantly associated with TFPM, duration of meconial stools, and DF < T0 (adjusted odds ratio [95% confidence interval]: 1.00 [0.99-1.03], 1.16 [0.86-1.55] and 0.97 [0.72-1.31], resp.).
    CONCLUSIONS: In this cohort, no association was found between TFPM, duration of meconium stool, and DF < T0 and the development of NEC.
    BACKGROUND: • Necrotizing enterocolitis (NEC) is a life-threatening acute intestinal inflammatory disease of the young preterm infant. Early clinical risk factors for NEC have been investigated in order to facilitate early diagnosis and treatment. • Signs of disrupted gastrointestinal mobility, such as gastric retention and paralytic ileus, have been established to support the diagnosis of NEC. Nevertheless, defecation patterns have insufficiently been studied in relation to the disease.
    BACKGROUND: • Defecation patterns in the three days preceding NEC did not differ from gestational age-matched controls of corresponding postnatal age. Additionally, the first passage of meconium and the duration of meconium passage were comparable between cases and controls. Currently, defecation patterns are not useful as early warning signs for NEC. It remains to be elucidated whether these parameters are different based on the location of intestinal necrosis.
