Gastro-intestinale ziekteleer
- Slokdarm: achalasie, slokdarmspasmen, GERD & maligne tumoren
- Maag: ulcuslijden, gastritis, maligne tumoren
- Functionele darmstoornissen: IBS, functionele dyspepsie
- Coeliakie
- Inflammatoire darmziekten: ziekte van Crohn, colitis ulcerosa
- Diverticulitis = ontsteking van kleine uitstulpingen in dikke darm (divertikels)
- Hemorroïden
Slokdarm (oesophagus)
- Functie: aboraal transport van voedselbolus & speeksel + voorkomen van
reflux van maaginhoud
- Via: peristaltiek (primaire, secundaire), sfinctermechanismen (cricopharyngeus,
GES) & neuronale controle (inhibitie & excitatie)
- Peristaltiek: spieren contraheren waardoor de passageweg smaller wordt & de
voedselbolus naar beneden wordt getrokken => bij voedselbolus relaxeren
spieren waardoor passageweg breder wordt zodat voedselbolus kan passeren
- Symptomen bij slokdarmpathologie: dysfagie (moeilijk slikken), odynofagie (pijn
bij slikken), regurgitatie (terug naar boven komen van onverteerd voedsel),
pyrosis (reflux), aspiratie(maaginhoud komt via mond terug naar binnen =>
longen), gewichtsverlies, bloedverlies, globusgevoel, halitose (slechte
ademgeur) examen
- Onderzoek bij slokdarmpathologie: examen
o Oesophagoscopie: met endoscoop kijken of mucosa ontstoken is van
slokdarm
, 10
o Röntgenonderzoek: met contrastvloeistof => kijken of contrastvloeistof bijft
hangen (tumoren)
o Manometrisch onderzoek: verschillende kanalen in slokdarm om peristal te
meten, volgt normaal een bepaald patroon => indien afwijkingen wijst dit op
een pathologie (als contracties allemaal tegelijk gebeuren)
o Ambulante pH meting: buisje met meetpunten voor pH te meten gedurende
24u, indien reflux = lagere pH in slokdarm (want maagzuur komt in slokdarm)
▪ Gouden standaard voor diagnose GERD
▪ Kwantificatie tijd dat mucosa blootgesteld wordt aan maagzuur
▪ Meet vermogen van slokdarm om refluxzuur te clearen
o Impedantie meting: meting elektrische weerstand, indien er een voedselbolus
aanwezig is, zijn er veel ionen aanwezig dus lage impedantie
- Slokdarmpathologie:
o Motorische stoornissen:
▪ Achalasie (examen): een motiliteitsstoornis van de slokdarm,
progressieve ziekte gekenmerkt door dysfagie voor vast & vloeibaar
voedsel
• Prevalentie: 7-32/100 000
• Meestal tussen 40 & 60 jaar
• Geen peristaltiek in slokdarm = simultane contracties =>
slokdarm is heel breed
• Lage gastro-oesofageale sfincter (GES) dilateert niet, hoge GES
tonus
• Progressieve obstructie slokdarm => geen passage naar darm
• Oorzaak: denervatie van inhibitorische neuronen tgv
progressieve degeneratie ganglioncellen thv. myenterische
plexus in slokdarmwand => inhibitie valt weg
• Primair: idiopathisch => vermoedelijk auto-immuunziekte +
genetische predispositie
