要旨

Background & Aims:

Fully covered self-expandable metal stents (FCSEMSs) palliate distal malignant biliary obstruction (dMBO), but migration remains a limitation. We compared a finned anti-migration FCSEMS (AMS) with a conventional flared FCSEMS (CS).

Methods:

Retrospective cohort (April 2020-April 2024) of adults with unresectable dMBO undergoing ERCP with AMS or CS. Primary outcomes were stent migration and recurrent biliary obstruction (RBO). Time-to-event outcomes were analyzed using IPTW Cox models, with PSM for sensitivity.

Results:

Among 276 patients (CS 172; AMS 104), crude migration was lower with AMS (0.96% vs 7.6%; p=0.02). After IPTW adjustment, migration risk remained directionally lower but was not statistically significant (HR 0.23; 95% CI 0.03-1.80; p=0.16). Migration remained numerically lower after PSM (p=0.10). RBO risk was similar across groups.

Conclusions:

Anti-migration FCSEMSs demonstrated lower crude migration with similar patency (RBO risk), but adjusted analyses did not reach statistical significance.

Metallic Solids

Metallic Solids

Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.
All metallic solids exhibit high thermal and electrical conductivity, metallic luster, and malleability....

Bonding in Metals

Bonding in Metals

Metallic bonds are formed between two metal atoms. A simplified model to describe metallic bonding has been developed by Paul Drüde called the “Electron Sea Model”.

Molecular Comparison of Gases, Liquids, and Solids

Molecular Comparison of Gases, Liquids, and Solids

Particles in a solid are tightly packed together (fixed shape) and often arranged in a regular pattern; in a liquid, they are close together with no regular arrangement (no fixed shape); in a gas, they are far apart with no regular arrangement (no fixed shape). Particles in a solid vibrate about fixed positions (cannot flow) and do not generally move in relation to one another; in a liquid, they move past each other (can flow) but remain in essentially constant contact; in a gas, they move...

Sign Convention

Sign Convention

When analyzing a beam subjected to various loads, it is crucial to understand the internal forces and moments generated within the structure. These internal forces can be broadly classified into normal forces, shear forces, and bending moments. To determine these forces and moments, we use the method of sections and apply a specific sign convention based on their direction and the side of the section being analyzed.
The normal force acts perpendicular to the beam's cross-section and can...

The Sense of Self: Reflected Self-Appraisal and Social Comparison

The Sense of Self: Reflected Self-Appraisal and Social Comparison

According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Lattice Centering and Coordination Number

Lattice Centering and Coordination Number

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.

Imagine taking a large number of identical...
