まとめ
植物由来物の摂取は小腸穿孔を引き起こし、虫垂炎を模倣する可能性があります。グネツム・グネモンの木片が回腸穿孔を引き起こした症例報告で、画像診断の限界を強調しています。
科学分野:
- 消化器病学;外科病理学;医用画像診断
背景:
- 植物由来物の摂取は、小腸穿孔のまれな原因である。;臨床像は急性虫垂炎を模倣する可能性があり、診断上の課題となる。
研究 の 目的:
- 摂取した植物由来物による小腸穿孔の症例を報告する。;このような症例における画像診断の限界を強調する。;特定の地域における植物由来物摂取による急性腹症の文献に寄与する。
主な方法:
- 右下腹部痛を呈した40歳タイ人男性の症例報告。;診断ワークアップには、検査および造影CT検査が含まれた。;画像診断が不明瞭であったにもかかわらず、持続的な腹膜炎のため、開腹手術が施行された。
主要な成果:
- CTでは虫垂の軽度拡張が認められたが、異物や穿孔の明らかな兆候はなかった。;開腹手術により、回腸末端のグネツム・グネモン由来の2.5cmの木片が発見され、穿孔を引き起こしていた。;この異物は摘出され、回腸の欠損部は修復され、虫垂切除術が施行され、術後の経過は無合併症であった。
結論:
- 本症例は、摂取した異物による小腸穿孔の診断における従来の画像診断の限界を強調する。;特にそのような食品が一般的な地域では、植物由来物摂取を急性腹症の鑑別診断に含めるべきである。;画像診断で確定できない場合でも、臨床的疑いが強い場合には、迅速な外科的介入が必要となる場合がある。

Esophageal Perforation-I: Introduction
844
Esophageal perforation is a severe medical condition characterized by a breach in the integrity of the esophageal wall. This breach can occur due to various factors such as trauma, medical procedures, or underlying diseases. When the esophageal wall is compromised, it allows food, fluids, and digestive juices into the chest cavity or adjacent structures, leading to potential complications and health risks.
The location of esophageal perforation can vary, occurring anywhere along the esophagus....

Esophageal Perforation-II: Clinical Manifestations and Management
1.1K
Esophageal perforations manifest in various clinical forms, influenced by factors such as the perforation's cause and location (cervical, intrathoracic, or intra-abdominal), the extent of contamination, and potential injury to adjacent mediastinal structures. The timing between the perforation occurrence and treatment initiation also affects the clinical presentation.

Appendicitis-I: Introduction
4.4K
The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...

Inflammatory Bowel Disease I: Ulcerative Colitis
1.5K
Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Intestinal Obstruction II: Pathophysiology
47
Intestinal obstruction triggers a series of physiological responses, starting with gas and fluid accumulation in the bowel segment proximal to the obstruction, leading to distension. This distended intestine compresses the diaphragm, hindering lung expansion and potentially leading to reduced respiratory effort, atelectasis, and pneumonia.To overcome the blockage, the gut intensifies contractions, causing colicky abdominal pain, nausea, and vomiting, which reduces fluid and food intake and...

Appendicitis
29
Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...
