まとめ
内視鏡的逆行性胆管膵管造影(ERCP)は膵管閉塞に対して失敗することがある。内視鏡的超音波検査(EUS)ガイド下膵管ドレナージは、治療が必要な患者に対して、成功裏の低侵襲代替法を提供する。
科学分野:
- 消化器病学
- インターベンショナル内視鏡
- 肝胆膵外科
背景:
- 膵管閉塞は疼痛および膵萎縮を引き起こす。
- 内視鏡的逆行性胆管膵管造影(ERCP)は標準的な治療法である。
- 乳頭経由ERCPは、解剖学的困難または膵管異常により失敗することがある。
研究 の 目的:
- EUSガイド下膵管ドレナージの臨床的成功を評価すること。
- EUSガイド下ドレナージを複雑な症例に対する手術の代替法として評価すること。
- ERCPに失敗した患者における有効性を判断すること。
主な方法:
- EUSガイド下膵管ドレナージを受けた46人の患者(2016-2022年)の後ろ向きレビュー。
- 臨床的成功は、疼痛軽減(VAS≦2)および膵炎再発の不在によって定義された。
- 体重減少を伴う慢性膵炎に対しては、体重安定または増加を使用した。
主要な成果:
- 技術的成功は患者の93.5%で達成された。
- 技術的成功を収めた患者の臨床的成功率は93%であった。
- 疼痛再発率(9.3%)および膵炎再発率(6.9%)は低かった。
結論:
- EUSガイド下膵管ドレナージは、非常に成功率の高い低侵襲手技である。
- ERCPに失敗した症候性膵管狭窄患者に対して、有効な代替法を提供する。
- この手技は、良性または悪性の病因による膵臓手術を回避するのに役立つ可能性がある。

Observational Studies

Observational studies are a type of analytical study where researchers observe events without any interventions. In other words, the researcher does not influence the response variable or the experiment's outcome.
There are three types of observational studies – Prospective, retrospective, and cross-sectional.
Prospective Study
Prospective studies, also known as longitudinal or cohort studies, are carried out by collecting future data from groups sharing similar characteristics. One...

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.

Naturalistic Observations
17.4K
If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

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...

Center of Gravity
2.2K
The center of gravity is the point at which an object's weight appears to be concentrated and can be used to balance the object perfectly. This point is essential in mechanics as it provides information regarding a body's stability and moments of inertia. The center of gravity does not always have to fall within the shape or boundaries of the body; it may also lie outside the body in certain cases.
To determine its location, the principle of moments can be utilized by dividing the object into...

Cavity Drainage and Flashings in Masonry walls
471
Typically, a cavity wall consists of two wythes separated by a gap of at least 2 inches, which may contain insulation while still maintaining a minimum clear space of 1 inch to facilitate adequate drainage. Advanced methods like the insertion of a continuous drainage mat can further reduce this space while ensuring effective moisture expulsion.
Weep holes, strategically placed at the base of the cavity, are critical for draining accumulated water. These openings are created by leaving head...
