まとめ
逆行性バルーン拡張術は、良性食道狭窄の治療において安全かつ効果的な方法であり、順行性方法と同等の技術的成功率を示した。この技術は、食道狭窄患者における再拡張の必要性を減らす可能性もある。
科学分野:
- 消化器病学;インターベンショナル内視鏡検査;食道疾患
背景:
- 良性食道狭窄(BES)は、一般的に順行性Savary拡張法または静的バルーン拡張法で管理される。;逆行性バルーン拡張術は、BES管理に利点をもたらす可能性のある修正された技術である。;逆行性バルーン拡張術に関する有効性と安全性データは限られている。
研究 の 目的:
- 良性食道狭窄に対する逆行性バルーン拡張術の有効性と安全性を評価すること。;単一施設での経験において、逆行性バルーン拡張術と順行性Savary拡張術を比較すること。
主な方法:
- BESを有する53例の患者を対象とした後向き研究で、逆行性バルーンプルスルー拡張術を受けた23例と順行性Savary拡張術を受けた30例を比較した。;主要評価項目は技術的成功(内腔径≥16 mm)であった。;副次評価項目には、1年以内の再拡張率および有害事象が含まれた。
主要な成果:
- 両手技ともに高い技術的成功率を示した:逆行性バルーンプルスルー法は95.7%、順行性Savary拡張法は100%(P = .434)。;逆行性バルーンプルスルー法では、再拡張率が低い傾向が観察された(22例中4例 vs 30例中12例、P = .076)。;逆行性群では軽微な有害事象が1件報告されたのみであった。
結論:
- 逆行性バルーンプルスルー拡張術は、単純および複雑な良性食道狭窄の管理において有効かつ安全である。;この技術は、従来の順行性方法に代わる実行可能な選択肢を提供する。;さらなる研究により、再治療率を低下させる可能性が確認される可能性がある。

Esophageal Strictures-I: Introduction
884
Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous).
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...

Esophageal Strictures-II: Clinical Features and Management
672
Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

Pilot and Numeric Relaying
492
Pilot relaying is a type of differential protection used in power systems. It compares electrical quantities at the terminals of equipment via a communication channel instead of direct relay interconnection. This method is essential for transmission lines where the terminals are far apart, typically up to 80 km for lines with 69 to 115 kV ratings. Four types of communication channels are used for pilot relaying:

Lattice Centering and Coordination Number
11.7K
The structure of a crystalline solid, whether a metal or not, is best described by considering its simplest repeating unit, which is referred to as its unit cell. The unit cell consists of lattice points that represent the locations of atoms or ions. The entire structure then consists of this unit cell repeating in three dimensions. The three different types of unit cells present in the cubic lattice are illustrated in Figure 1.

Esophageal Varices-I: Introduction
1.5K
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...

Center of Gravity
6.7K
The center of gravity (COG) of an object is the point where the object's total weight is considered to be concentrated. Knowing the location of the center of gravity is useful when predicting the behavior of a moving object or designing static structures. In a uniform gravitational field, the center of gravity is similar to the center of mass (COM); yet, these two points can be positioned differently. For example, the Moon's center of mass lies very close to its geometric center, but...
