Ntau npaum li cas Stents Paub - suav cov "Low key" Non Vascular Stents

Thaum nws los txog rau stents, qhov paub zoo tshaj plaws yog vascular stents (xws li coronary thiab peripheral vascular stents). Kev mob hnyav ntawm cov hlab ntsha ntawm cov hlab ntsha tuaj yeem ua rau txo qis hauv kev ua neej zoo ntawm cov neeg mob thiab txawm hem lawv lub neej. Yog li ntawd, stents yuav tsum tau muab tso rau kom rov qab cov ntshav txaus. Tab sis puas tsuas muaj cov hlab ntsha hauv cov hlab nqaim ntawm tib neeg lub cev? Cov lus teb yog inevitably tsis zoo. Tsis muaj vascular lumens xws li txoj hlab pas, txoj hlab ntsws, kab mob hauv plab, thiab plab hnyuv hauv tib neeg lub cev kuj tuaj yeem nqaim vim qee qhov laj thawj (cov qog, anastomotic fistulas, thiab lwm yam), uas ua rau muaj cov tsos mob xws li kev noj zaub mov nyuaj lossis ua pa, jaundice. , thiab lwm yam. Ntawm no, siv cov tsis muaj vascular stents xws li esophageal, ua pa, biliary, thiab plab hnyuv stents rau kev kho mob tuaj yeem txhim kho tus neeg mob lub neej zoo los yog tsim lub hauv paus zoo rau kev xaiv phais los ntawm kev txhawb nqa nqaim lumen.

1. Esophageal stent:

Esophageal stenosis muaj xws li benign thiab malignant stenosis, uas tuaj yeem ua rau cov tsos mob xws li nqos nyuaj rau cov neeg mob. Benign stenosis feem ntau yog tshwm sim los ntawm kab mob gastroesophageal reflux, phais, kho hluav taws xob, kho ablation, corrosive ingestion, thiab tshuaj puas tsuaj, thiab tuaj yeem kho nrog stents ib ntus (feem ntau yog them stents, tshem tawm hauv ib hlis); Malignant esophageal stenosis feem ntau tshwm sim los ntawm kev mob qog noj ntshav hauv plab, kab mob hauv siab malignant, thiab qog nqaij hlav malignant infiltration rau hauv txoj hlab pas. Tam sim no, kev siv cov esophageal stents los txo cov stenosis esophageal stenosis tau dhau los ua ib txoj kev kho mob tseem ceeb rau malignant esophageal stenosis.

Scope ntawm daim ntawv thov kev pab txhawb esophageal

Haum rau kev kho mob ntawm benign lossis malignant esophageal strictures, anastomotic strictures, thiab strictures tom qab radiotherapy.

2. Ua pa stent

Cov kab mob ua pa tau muab faib ua cov kab mob ua pa sab saud thiab sab qis, thiab cov hlab ntsws infarction tuaj yeem ua rau cov tsos mob xws li ua tsis taus pa thiab ua pa nyuaj. Airway stenosis yog hais txog qhov nqaim ntawm trachea thiab bronchial lumens tshwm sim los ntawm ntau yam kab mob benign lossis malignant airway kab mob. Cov ua rau benign central airway stenosis muaj xws li tracheobronchial tuberculosis, mus sij hawm ntev tracheal intubation los yog tracheostomy, sarcoidosis, tracheobronchial amyloidosis, thiab lwm yam; Malignant stenosis yog tshwm sim los ntawm thawj los yog metastatic qog ntawm lub trachea, carina, sab laug thiab txoj cai lub ntsiab bronchi, thiab nruab nrab bronchi, nrog rau cov qog malignant invading los yog compressing cov kabmob uas nyob ib sab.

Muaj feem cuam tshuam txog kev ua pa stent

Haum rau dilation kev kho mob ntawm benign los yog malignant stenosis ntawm trachea thiab bronchus.

3.Biliary stent

Cov kab mob biliary muaj lub luag haujlwm ntawm kev zais, khaws cia, tsom mus, thiab thauj cov kua tsib, uas ua lub luag haujlwm tseem ceeb hauv kev tso tawm cov kua tsib mus rau hauv duodenum. Yog hais tias muaj cov kab mob benign los yog malignant nyob rau hauv cov kua tsib los yog ib feem ntawm cov kua tsib duct, nws yuav cuam tshuam cov ndlwg ntawm cov kua tsib mus rau hauv lub duodenum los ntawm cov kua tsib duct, ua rau kom lub siab nyob rau hauv lub bile duct, ua rau cov kua tsib reflux los ntawm daim siab. cell thiab capillaries rau hauv cov ntshav sinuses thiab perisinuses, ua rau kom nce qib ntawm conjugated bilirubin hauv cov ntshav thiab ua rau jaundice. Cov kab mob qog nqaij hlav tsis zoo yog tshwm sim los ntawm cov qog, thiab yog tias qhov cuam tshuam ntev dhau lawm, nws tuaj yeem ua rau muaj kev puas tsuaj rau lub cev tseem ceeb. Tam sim no, biliary stent implantation tau dhau los ua ib txoj kev kho mob tseem ceeb, uas tuaj yeem txo lossis tshem tawm jaundice, txhim kho cov neeg mob tag nrho, thiab txhim kho lawv lub neej zoo.

Muaj feem cuam tshuam ntawm biliary stent

Feem ntau yog siv rau kev kho mob ntawm biliary stenosis.

4.Intestinal stent

Cov hnyuv yog cov ducts ntev tshaj plaws hauv lub plab zom mov, suav nrog duodenum, jejunum, ileum, cecum, txoj hnyuv, thiab lub qhov quav. Thaum lub plab hnyuv stenosis los yog kev cuam tshuam yog tshwm sim los ntawm cov qog malignant siab los yog lwm yam mob qog nqaij hlav hauv plab, nws tuaj yeem ua rau nyuaj rau kev zom zaub mov, nqus, thiab defecation. Kev siv cov hlau stents mus tas li lossis ib ntus txhawb nqa qhov nqaim lossis cuam tshuam ntawm cov kab noj hniav tuaj yeem rov ua dua patency thiab tsim cov xwm txheej rau kev xaiv phais.

Scope ntawm kev siv cov hnyuv stent

Haum rau kev kho mob ntawm plab hnyuv stenosis, kev cuam tshuam, lossis anastomotic stenosis hauv tib neeg lub cev (duodenum, transverse colon, descending colon, sigmoid colon, rectum).
