Altered Mental Status as the Primary Presentation of Intussusception in a 3-Month-Old Child Diagnosed by Point-Of-Care Ultrasonography

BackgroundIntussusception can lead to significant morbidity in affected children secondary to tissue ischemia and necrosis. When a child outside of the classic age range presents with symptoms other than intermittent abdominal pain, the diagnosis of intussusception can be difficult and is often delayed.Case ReportWe present the case of a three-month-old boy who presented to the emergency department with waxing and waning mental status and seizure-like activity who was ultimately diagnosed with intussusception. The effective use of bedside ultrasonography, by the attending pediatric radiologist, enabled an interdisciplinary team to explore abdominal etiologies in parallel with testing for more commonly seen causes of altered mental status. This led to an expedited diagnosis and successful definitive management.Why Should an Emergency Physician Be Aware of This?Intussusception is a common pediatric emergency encountered by emergency physicians where a timely diagnosis can have a profound impact on patient outcomes. Previous case reports highlight how easily intussusception can be overlooked with this atypical neurologic presentation. Furthermore, because patients with profound altered mental status are often too ill to leave the emergency department for diagnostic testing, bedside abdominal ultrasonography may be helpful in these patients.     

10Gyγ线照射后小鼠两相邻肠段运动变化

本文用同时记录两相邻空肠段的收缩活动来观察经10Gyγ线照射后小肠运动的变化,以了解照射后是否出现逆蠕动,以便进一步分析肠套叠形成的原因.结果表明,照射后两相邻肠段出现强度不一的收缩活动,并且可以产生逆蠕动;但是这种逆蠕动发生的机率是不大的.本实验未观察到逆蠕动发生的规律性.因此,逆蠕动的产生可能是照射后发生肠套叠的部分原因.     

小儿肠套叠空气灌肠复位影响因素探讨

目的 分析空气灌肠治疗小儿肠套叠的各种影响因素。方法 对117例确诊肠套叠的患儿，采用双腔气囊外接压力计或不接压力计，在X线透视下行空气灌肠。结果 117例中，完全复位92例(78％)，复位失败17例(14．5％)，不完全复位8例(6％)。结论 空气灌肠是治疗小儿肠套叠的重要方法，其影响复位成功与否的因素，主要有套入时间、类型、复位方法等。     

Intussesception after jejunoileal bypass as diagnosed by ultrasound

Eighty patients who had undergone jejunoileal bypass for morbid obesity were examined by ultrasound at their routine follow-up visits to the clinic. Ultrasonographic evidence of intestinal intussusception was found in 15 patients (19%). Two of these patients were asymptomatic. Ultrasonographic findings were confirmed by operation in 6 patients (5 with intussusception, 1 negative).     

超声在小儿急腹症中的应用价值和经验探讨

目的研究彩色多普勒在小儿消化系统急腹症中的应用价值。方法回顾性分析阐述2019年1-12月期间医院收治的136例急腹症患儿的超声检查和临床资料,分析彩色多普勒超声诊断的符合率。结果彩色多普勒超声诊断急性肠系膜淋巴结炎符合率92.86%,急性阑尾炎符合率90.91%,肠套叠符合率97.44%,肠旋转不良伴中肠扭转符合率100%,肠梗阻符合率100%。结论彩色多普勒超声在诊断小儿急腹症中具有较高的符合率,是小儿急腹症首选的检查方法。     

Colo-colic intussusception secondary to colon lipoma: A case report

Introduction and importanceIntestinal intussusception is rare in adults and it is associated with lead points affecting the colon in around 17% of patients. Lipomas are very rare benign tumors which may act as lead points for intestinal intussusception. Indeed, the incidence of intestinal intussusception is much rare when caused by lipomas.Case presentationOur patient is a 29-year-old male, previously healthy and admitted for severe right lower quadrant abdominal pain of 2-day duration. Computed tomography (CT) scan of the abdomen and pelvis showed large mass of fat consistency containing colon structure.Clinical DiscussionUrgent laparotomy was opted during which colo-colic intussusception was diagnosed and right hemicolectomy with primary ileocolic anastomosis was performed. Pathology report showed that intussusception was induced by a colon lipoma. Patient had an uneventful hospital stay and was discharged on post-operative day 5.ConclusionThus we recommend that colo-colic intussusception caused by lipoma be considered in the differential when diagnosing adults with right lower quadrant pain.     

改良新产程模式管理硬膜外麻醉无痛分娩产程对母婴结局的影响

目的探讨应用改良新产程模式管理硬膜外麻醉无痛分娩产程对母婴结局的影响。方法选取2018年1月-2020年2月在长春市妇产医院自愿行硬膜外麻醉无痛分娩的单胎初产足月妊娠产妇220例为研究对象,随机分为观察组和对照组,每组各110例。观察组产妇应用改良新产程模式管理无痛分娩,对照组产妇应用新产程模式管理产程无痛分娩。观察两种产程管理模式管理产程对母婴结局影响。结果观察组产妇潜伏期、加速期及第二产程时间均较对照组明显缩短,差异均有统计学意义(均P<0.01)。两组产妇剖宫产率和产后出血率比较,差异无统计学意义(P>0.05)。观察组产妇阴道助产率明显低于对照组,差异有统计学意义(P<0.05)。观察组产妇产后出血量明显少于对照组,差异有统计学意义(P<0.05)。观察组新生儿脐动脉血pH值<7.2比例低于对照组,差异有统计学意义(P<0.05)。结论采用改良新产程模式管理的硬膜外麻醉无痛分娩产妇产程时限明显缩短,阴道助产率降低,产后出血量明显减少,新生儿脐动脉血pH值<7.2比例明显降低,因此改良新产程模式管理产程,可有效保证母婴安全。     

Intra-anal intussusception: diagnosis by posteroanterior stress proctography

Intra-anal intussusception was diagnosed in eight of 39 patients on evacuation proctography. Posteroanterior views revealed prolapse of the infolded rectum into the anal canal on straining in seven of eight patients, associated with splaying open of the anal canal and sudden distal movement of the fold during prolapse. Similar changes were seen in four of 31 patients in whom intussusception had not been diagnosed on lateral evacuation proctography. The pattern of the collapsed rectum was assessed for fold length, thickness, and angulation in relation to the midline of the rectum. Infoldings that prolapsed were closer to the anorectal junction on stress (mean 14.6 42.4 mm, p < 0.0001) showed greater change in height between rest and strain (28.8 14.6 mm, p < 0.05) and became more acutely angled during straining (41.9 5.3°, p < 0.01). Intra-anal intussusception may be missed in 33% (four of 12 patients) on routine evacuation proctography. Posteroanterior stress proctography is a simple supplementary examination to validate intussusception.
