Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies01:28

Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies

742
Peptic ulcer disease (PUD) presents with diverse symptoms depending on the location and severity of the ulcer. Clinical manifestations of peptic ulcer include dull pain and a burning sensation in the mid-epigastric region.
Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.

Peptic Ulcer Disease I: Introduction

981
Peptic Ulcer Disease (PUD) is characterized by mucosal excavation in the esophagus, stomach, pylorus, or duodenum. It can manifest as acute or chronic based on the extent and duration of mucosal involvement.
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
Peptic ulcers can also be...

Chronic Pancreatitis I: Introduction

842
The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

Other Disorders of Digestive System

1.7K
The gastrointestinal tract is susceptible to various disorders. If the lower esophageal sphincter is damaged, stomach acid can flow back into the esophagus, causing irritation and inflammation of the lining. This condition is called gastroesophageal reflux disease (known as heartburn) and may cause chest pain and difficulty swallowing. In the stomach, prolonged use of nonsteroidal anti-inflammatory drugs like aspirin, chronic alcohol consumption, bacterial infections such as Helicobacter...

Pathophysiology of Peptic Ulcer Disease: Injurious Factors

1.4K
Peptic ulcers are sores on the stomach's inner lining and the upper small intestine, which are the result of disruptions in the mucosal layer that houses parietal cells which produce gastric acid, and chief cells which secrete pepsinogen.
In the antrum region, G cells secrete the gastrin hormone that binds to gastrin-cholecystokinin-B (CCK2) receptors on parietal and enterochromaffin-like (ECL) cells in the fundic glands. Simultaneously, the vagus nerve releases acetylcholine, which binds...

Gastritis-II: Pathophysiology01:17

Gastritis-II: Pathophysiology

1.7K
Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

    患者の2.8%で診断される症状性十二指腸炎は,十二指腸潰瘍につながる可能性があります. これは,十二指腸炎が潰瘍スペクトルの一部であり,独立した状態ではないことを示唆しています.

    • 胃腸内科 胃腸内科
    • 病理生理学 病理生理学とは
    • 内視鏡診断による診断

    背景:

    • 十二指腸炎は,小腸の最初の部分である十二指腸の炎症です.
    • 十二指腸潰瘍との関連については議論されており,前駆体または同時発症の症状と見なす人もいます.

    研究 の 目的:

    • 併存する十二指腸潰瘍のない症状性十二指腸炎の自然経歴を調査する.
    • 十二指腸炎は,十二指腸潰瘍疾患の発達における独立した実体か,または段階であるかどうかを判断する.

    主な方法:

    • 30ヵ月間にわたって502の光線性食道胃腸門鏡検査を遡及的に分析した.
    • 症状性十二指炎と診断された14人の患者 (2.8%) の追跡調査は1~3年半にわたって行われました.
    • 繰り返しの内視鏡検査と二重コントラストバリウム粉を用いて,ヒストロジカル検査 (ヘマトキシリンとエオシン) を含むフォローアップ評価を行った.

    主要な成果:

    • 最初の十二指腸炎を患った14人の患者のうち6人 (42.8%) が後に十二指腸潰瘍を発症し,全員が手術を必要とした.
    • さらに2人の患者は,再発した十二指腸炎による絶え間ない消化不良を報告し,組織学的に確認した.
    • 残りの患者は症状のない状態で,内視鏡検査の繰り返しで十二指管内膜が正常または軽く炎症していた.

    結論:

    • 症状のある十二指腸炎は十二指腸潰瘍の発症に先行する可能性があります.
    • 研究結果は,十二指腸炎は十二指腸潰瘍の病理生理学的スペクトルの一部であり,潜在的に活性または治癒段階を表していることを示唆しています.
    • 十二指腸炎は,独立した疾患ではなく,十二指腸潰瘍疾患の連続体内の症状である可能性があります.
