まとめ
外科的クリップの移動は、胆嚢摘出術から数年後の胆道閉塞の原因となる可能性があります。この症例では、移動したクリップの周りに形成された総胆管結石を治療するために、胆管鏡ガイド下砕石術が使用されました。
科学分野:
- 消化器病学
- 外科的合併症
- 胆道インターベンション
背景:
- 外科的クリップの移動は、胆嚢摘出術後の遅発性合併症のまれではあるが重要な原因です。
- 遅発性胆道閉塞は、特に異物の移動に関連する場合、診断上の課題を提示します。
研究 の 目的:
- 腹腔鏡下胆嚢摘出術後の移動性外科的クリップによる遅発性胆道閉塞の症例を報告すること。
- このような合併症の管理における胆管鏡検査および体外衝撃波結石破砕術を伴うERCPの有効性を例示すること。
主な方法:
- 胆嚢摘出術の既往歴のある患者が胆道閉塞の症状を呈しました。
- 画像診断により総胆管結石が明らかになりました。
- 胆管鏡検査を伴うERCPにより、結石の巣としての移動性外科的クリップが特定されました。
- 体外衝撃波結石破砕術が結石破砕に使用され、その後バルーン抽出とステント留置が行われました。
主要な成果:
- 移動した外科的クリップが総胆管結石の巣であることが特定されました。
- 体外衝撃波結石破砕術は結石を効果的に破砕しました。
- 患者は、内視鏡的介入およびステント留置後の合併症のない回復を経験しました。
結論:
- 胆嚢摘出術後の遅発性胆道閉塞の鑑別診断においては、クリップ移動を考慮すべきです。
- 胆管鏡ガイド下体外衝撃波結石破砕術は、移動したクリップに関連する複雑な総胆管結石に対する実行可能で効果的な治療法です。

Migration
8.9K
Migration is long-range, seasonal movement from one region or habitat to another. This common strategy, carried out by many different organisms around the world, is an adaptive response that typically corresponds to changes in an organism’s environment, like resource availability or climate. Migrations can involve huge groups of thousands of animals as well as single individuals traveling alone and can range from thousands of kilometers to just a few hundred meters.

Cell Migration
6.5K
Cell migration is a process by which the cells move from one location to another, playing an essential role in embryological development, repair and regeneration, immune response, and metastasis. Cells migrate in response to chemical or mechanical signals generated by specific organs or tissues. The overall mechanism includes three steps - polarization, protrusion, and release. Polarization involves the formation of a distinct cell front and rear, which determines the direction of movement.

Cell Migration

Cell migration, the process by which cells move from one location to another, is essential for the proper development and viability of organisms throughout their life. When cells are not able to migrate properly to their ordained locations, various disorders may occur. For example, disruption in cell migration causes chronic inflammatory diseases such as arthritis.

Cancer Cell Migration through Invadopodia
3.3K
Invadosome is a broad category of cell surface structures with proteolytic activity that degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...

Chemotaxis and Direction of Cell Migration
4.6K
Cells can detect chemical cues in their environment and reorganize the cytoskeleton to migrate toward them or away from them. This directional migration, called chemotaxis, is essential during embryogenesis and development, immune response, tissue repair and regeneration, and reproduction. These chemical cues can either attract or repel the cell's movement. For example, axon development is determined by a combination of chemoattractants and chemorepellents that direct the growing axon...

Role of Myosin in Cell Migration
3.3K
Myosins are multimeric motor proteins involved in various cellular processes such as migration, adhesion, and proliferation. Myosin II is the most common type in animal cells, which binds and cross-links actin filaments.
Myosin II is a hexamer comprising two heavy chains with globular heads and coiled-coil tails, two regulatory light chains, and two essential light chains. The ATPase sites on the myosin heads hydrolyze ATP, and the released phosphate generates the force for contraction....
