まとめ
大腸憩室出血(CDB)の内視鏡的治療は高い成功率を示す。スルーザスコープ(TTS)クリップは予後が悪く、内視鏡的デタッチャブルスネア結紮(EDSL)は有害事象が多かった。
科学分野:
- 消化器病学; 内視鏡外科学; 臨床研究
背景:
- 大腸憩室出血(CDB)は、急性下部消化管出血の頻繁な原因である。 スルーザスコープ(TTS)クリップ、内視鏡的バルーン結紮(EBL)、内視鏡的デタッチャブルスネア結紮(EDSL)、オーバースコープクリップ(OTSC)など、様々な内視鏡治療法が存在する。
研究 の 目的:
- CDBに対する様々な内視鏡治療法の有効性と安全性を系統的にレビューし、メタアナリシスを行うこと。
主な方法:
- PubMed、Embase、Cochrane Libraryデータベースを検索した。 プール推定値と95%信頼区間(CI)を計算する比例メタアナリシスを実施した。 内視鏡治療法に基づくサブグループ解析を実施し、P < 0.10を有意差ありとみなした。
主要な成果:
- 観察研究21件(参加者3,161人)を対象とした。 プールされた成功止血率は98.90%(95% CI 97.66-99.75%)で、サブグループ間に有意な差はなかった。 TTSクリップは再出血および処置時間において予後が悪かった。 EDSLは有害事象発生率が最も高かった(2.15%)。
結論:
- CDBの内視鏡治療は、すべての治療法において高い即時止血率を提供する。 TTSクリップは予後不良と関連していたが、入院期間または死亡率に有意差のある治療法はなかった。 EDSLは有害事象の頻度が高いことと関連していた。

Esophageal Varices-II: Clinical Features and Management
334
Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
In the initial assessment, a thorough review of the patient's medical history is vital to identify risk factors such as liver disease, alcohol...

Inflammatory Bowel Disease V: Surgical Management
420
Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:

Endoscopic Procedures II: Colonoscopy
541
The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
604
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Esophageal Varices-I: Introduction
1.1K
Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy
496
Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...
