まとめ
穿刺内視鏡胃瘻造設術(PEG)抜去後の胃穿孔遅延は稀である。本症例は、PEG抜去後6年を経て発症した生命を脅かす腹壁敗血症について詳述し、良好な転帰のためには迅速な外科的介入の重要性を強調する。
科学分野:
- 消化器病学; 外科腫瘍学; 感染症学
背景:
- 経皮内視鏡的胃瘻造設術(PEG)は、長期経管栄養のための一般的な手技である。一般的に安全であるが、抜去後の持続的な瘻孔などの合併症が発生する可能性がある。胃穿孔の遅延は極めて稀な合併症である。
研究 の 目的:
- PEG抜去後6年を経て発症した皮下胃穿孔の稀な症例を報告する。この稀な合併症の診断上の課題と管理を強調する。早期外科的介入の重要性を強調する。
主な方法:
- 食道気管瘻とPEG依存の既往がある24歳男性の症例報告。発熱、腹痛、腹壁腫脹の臨床症状。皮下気腫と液体貯留を示す診断画像(CTスキャン)。緊急外科的探査、胃の修復、軟部組織感染症の管理。
主要な成果:
- 患者は胃内容物が皮下腔に流入することによる壊死性軟部組織感染症を呈した。緊急手術では、胃の一次修復、瘻孔の切除、広範なドレナージが行われた。患者は集中治療、外科的根治的治療、抗菌薬療法後に回復した。
結論:
- PEG抜去後数年を経て発症する皮下胃穿孔の遅延は稀であるが、致命的となる可能性がある。臨床症状は壊死性軟部組織感染症に類似する可能性があり、高い疑いと早期の外科的探査が必要である。根治的治療と支持療法を含む迅速な外科的管理は、良好な転帰のために不可欠である。

Esophageal Perforation-I: Introduction
669
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
793
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.

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding
1.2K
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.

Endoscopic Procedures I: Esophagogastroduodenoscopy
1.5K
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:

The clinical manifestations of gastritis can vary depending on the cause and type of gastritis, but some common symptoms may include the following.
Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
