Summary
Lumen-apposing metal stents (LAMS) are used for pancreatic fluid collections and biliary access. More data are needed to compare LAMS models, but electrocautery aids placement for evolving clinical demands.
Area of Science:
- Gastroenterology and Endoscopy
- Medical Devices
Background:
- Lumen-apposing metal stents (LAMS) are increasingly utilized for transluminal interventions.
- Applications include complex pancreatic fluid collections (PFCs) and challenging biliary access.
Purpose of the Study:
- To review the current landscape of LAMS technology.
- To highlight the need for comparative data on various LAMS models.
- To discuss advancements in LAMS placement techniques.
Main Methods:
- Literature review of LAMS applications and advancements.
- Discussion of procedural techniques, including electrocautery-assisted placement.
- Analysis of current clinical use and future directions.
Main Results:
- Limited high-quality comparative data exist for different LAMS models.
- Electrocautery has streamlined LAMS placement, enabling single-step or 'hot' approaches.
- Operator expertise and device availability influence current LAMS use.
Conclusions:
- LAMS are valuable tools for complex endoscopic procedures.
- Further research is required to guide optimal LAMS selection and utilization.

52.9K
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”.

02:37Metallic Solids
20.9K
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.

25.0K
Group 1 elements are soft and shiny metallic solids. They are malleable, ductile, and good conductors of heat and electricity. The melting points of the alkali metals are unusually low for metals and decrease going down the group, while the density increases going down the group with the exception of potassium (Table 1).

The hemoglobin in the blood, the chlorophyll in green plants, vitamin B-12, and the catalyst used in the manufacture of polyethylene all contain coordination compounds. Ions of the metals, especially the transition metals, are likely to form complexes.
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

02:58Properties of Transition Metals
30.1K
Transition metals are defined as those elements that have partially filled d orbitals. As shown in Figure 1, the d-block elements in groups 3–12 are transition elements. The f-block elements, also called inner transition metals (the lanthanides and actinides), also meet this criterion because the d orbital is partially occupied before the f orbitals.

1.8K
The conduction of free electrons inside a conductor is best described by quantum mechanics. However, a classical model makes predictions close to the results of quantum mechanics. It is called the theory of metallic conduction.
In this theory, Newton's second law of motion is used to determine the acceleration of an electron in the presence of an applied electric field. Then, its velocity is expressed via this acceleration.
