概括
患有胃的儿童在禁食期间表现出异常的胃缓慢波,正常胃波较少,太胃波较多. 这项研究突出了电气胃学的重点.
科学领域:
- 胃肠病学 胃肠病学
- 儿科医学 儿科医学
- 生理学 生理学 生理学
背景情况:
- 胃衰竭,以延迟的胃排空而没有机械阻塞为特征,呈现出复杂的病理生理学与组织学异常,如卡哈尔的间歇细胞损失.
- 这些细胞变化可能会破坏胃慢波,这对于调节胃运动至关重要.
- 电气胃学 (EGG) 是一种评估胃慢波活动的非侵入性方法.
研究的目的:
- 在被诊断为胃衰竭的儿童中,系统地审查和元分析胃慢波异常的患病率和范围.
- 为了比较儿科胃衰竭患者和健康对照组的EGG发现.
主要方法:
- 系统审查和元分析遵循PRISMA指南,从创立到2023年9月搜索多个数据库 (MEDLINE,Embase,LILACS,Web of Science,Cochrane).
- 纳入标准:在6-18岁的患有胃衰竭的儿童中使用表面电胃镜的研究.
- 关键结果:常态胃,动态胃,布拉迪胃百分比,主导频率,功率比,刺激后功率变化和主导频率不稳定. 使用乔安娜·布里格斯研究所工具评估偏差风险;用于元分析的随机效应模型.
主要成果:
- 对涉及70名患者和15名对照组的四项研究的分析显示,与对照组相比,患有胃衰竭的儿童的禁食常态胃显著减少 (SMD = -3.363) 和禁食快速胃衰竭增加 (SMD = 3.287).
- 在胃性儿童中观察到明显较低的功率比率 (SMD = -4.067),表明胃电活动发生了变化.
- 包含的研究提供了各种EGG参数的数据,分析强调了患者和对照组之间关键指标的显著差异.
结论:
- 患有胃的儿童在禁食期间表现出更高的太基胃的患病率和更低的正常胃的患病率.
- 在这些儿童中,刺激后功率变化的减少表明胃收缩和/或膨胀机制的潜在损伤.
- 电气胃学是一项有价值的工具,用于描述儿科胃的胃节律失常,为潜在的病理生理学提供了洞察力.

Gastrointestinal Motility Disorders
1.1K
Gastrointestinal or GI motility disorders are characterized by irregular gastrointestinal tract movements, disrupting food transit from the mouth to the anus. They are caused by damage or dysfunction in gut muscles or nerves. These disorders can cause symptoms such as severe constipation, diarrhea, abdominal pain, and swallowing difficulties. Disorders can affect any segment of the GI tract and range widely in severity, from common conditions like GERD to life-threatening conditions like...

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding
800
Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.

Gastroesophageal reflux disease, or GERD, is a persistent medical condition that affects many individuals worldwide. Its clinical manifestations can vary greatly, making diagnosis and management challenging for healthcare professionals. The following is a comprehensive overview of the clinical manifestations, assessment, and management strategies for GERD.
Clinical Manifestations
GERD presents itself in a multitude of ways, with symptoms varying from person to person. The hallmark symptoms are...

Endoscopic Procedures I: Esophagogastroduodenoscopy
862
An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:

Endoscopic Procedures V: ERCP
2.7K
Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

Gastric Emptying
3.3K
Gastric emptying occurs when the stomach gradually releases chyme into the duodenum. When the stomach is distended, it triggers the release of gastrin, a hormone that promotes gastric acid secretion to aid in digestion. Additionally, stomach distension contributes to peristaltic waves that propel gastric contents toward the pyloric region. The gastroenteric reflex, on the other hand, primarily stimulates peristalsis in the intestines, facilitating the movement of contents further along the...
