まとめ

遅い結腸通過 (CT) は,胃の空きが遅いこと (GE) と関連しており,結腸反射の抑制を示しています. 胃収納障害 (GA) と遅れたGEは,遅いCTと不協同排便 (DD) の患者で一般的です.

科学分野:

胃腸内科
神経胃腸内科
消化器の生理学

背景:

潜在的に神経反射を含む上部と下部胃腸 (GI) 機能障害の共存は一般的です.
大腸と胃の機能の相互作用を理解することは,胃腸運動障害の診断と管理に不可欠です.

研究の目的:

遅い結腸経路 (CT) と不協和性排便 (DD) の患者における胃収納障害 (GA) と胃の排泄遅延 (GE) の有病率を決定する.
CTやDDとGAの障害やGEの遅延との関係を調査する.

主な方法:

遅いCTまたはDDを記録した178人の成人の分析
99mTc-SPECTを用いたGAとGEの評価と,標準化された卵の食事後のシンチグラフィー.
変数間の関係を評価するためにスピアーマンランクテストを用いた相関分析.

主要な成果:

遅いCTは遅いGEと関連しており (35. 6%の患者で) コロガストリック反射阻害を示唆している.
DD (23. 7%) と遅いCT (26. 7%) の患者の有意な割合でGA障害が観察されました.
CTとGAの間の有意な相関は見つかりませんでしたが,CTはGEとの相関を示しました.

結論:

遅いCTは遅いGEと関連していますが,GAの障害はなく,コロガストリック反射の役割をサポートしています.
遅いCTとDDの患者では,GA障害と遅いGEの高い流行がある.
これらの発見は,上部と下部消化器官の運動障害の頻繁な同時発生を強調しています.

Drugs Affecting GI Tract Motility: Serotonin Receptor Agonists

400

Serotonin, a crucial neurotransmitter synthesized by enterochromaffin cells, plays a cardinal role in regulating gastrointestinal (GI) motility. With over 90% of the body's total serotonin in the GI tract, its influence on digestive processes is profound. Serotonin is swiftly released upon various stimuli, such as food boluses or certain drugs, triggering intrinsic sensory neurons in the myenteric plexus and extrinsic vagal and spinal sensory neurons. This leads to the activation of the...

Gastrointestinal Motility Disorders

594

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...

Drugs Affecting GI Tract Motility: Other Laxatives

457

Laxatives are primarily used to alleviate constipation, a common gastrointestinal disorder characterized by infrequent bowel movements and difficulty passing stools. They work by various mechanisms to increase the volume or frequency of bowel movements. The primary modes of action of laxatives include increasing stool bulk, softening the stool, stimulating intestinal motility, and osmotically drawing water into the intestines.
Osmotic or saline laxatives, like magnesium hydroxide or milk of...

Drugs for Treatment of Constipation-Predominant IBS

331

Pharmacological therapies for IBS-C are designed to alleviate abdominal discomfort and enhance bowel function. In patients with IBS-C, fiber supplements may help soften stools and decrease straining, but may also lead to increased gas production and bloating. Osmotic laxatives like milk of magnesia are frequently used to soften stools and increase stool frequency in IBS-C patients. In addition, two drugs approved for use in severe IBS-C adult cases are linaclotide (Linzess) and lubiprostone...

Drugs Affecting GI Tract Motility: Dopamine Receptor Antagonists

610

Prokinetic agents are specialized medications that stimulate gastrointestinal (GI) motility, promoting food movement through the GI tract. Dopamine, an inhibitory neurotransmitter, plays a significant role in this process, reducing GI motility and indirectly controlling the speed of digestion. Dopamine receptor antagonists, such as metoclopramide and domperidone, offer a unique advantage as prokinetic agents. By blocking the dopamine receptors, these drugs increase GI motility, improving food...

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

142

This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...
