Miv muaj peev xwm raug kev txom nyem los ntawm qee tus txheej txheem cem quav thoob plaws hauv lawv lub neej, tshwj xeeb tshaj yog muaj feem xyuam rau cov kev ntxhov siab uas lawv hnov mob heev, xws li kev hloov kho, kev hloov pauv hauv lawv txoj haujlwm, qhia txog tus tsiaj tshiab lossis tus neeg hauv tsev., los yog nws tuaj yeem muab tau los ntawm qee qhov kev cuam tshuam los yog cov txheej txheem neurological uas cuam tshuam rau txoj hnyuv thiab feem ntau muaj qhov kev pom zoo thaum qhov ua rau raug daws. Txawm li cas los xij, nyob rau lwm lub sijhawm, cem quav ntev los ntawm qee qhov ua rau cem quav ntev dhau lub sijhawm uas tsis tau daws, qee qhov hnyav dua, idiopathic lossis congenital pathological txheej txheem tuaj yeem ua rau tus miv tsim megacolon lossis, dab tsi zoo ib yam, dilation ntawm cov nyuv uas txuam nrog cov quav tawv hauv nws thiab hypomotility uas ua rau cem quav loj heev.
Yog koj xav paub qhov ua rau, tsos mob, kuaj mob thiab kev kho mob megacolon hauv miv, txuas ntxiv nyeem tsab xov xwm no ntawm peb lub xaib.
Megacolon hauv miv yog dab tsi?
Megacolon hauv miv txhais tau tias yog qhov hnyav thiab hloov tsis tau dilation ntawm txoj hnyuv nrog fecal retention thiab hypomotility ntawm txoj hnyuv. Hauv lwm lo lus, txoj hnyuv loj zuj zus, uas ua rau cov quav tso zis thiab poob suab, ua rau lub plab zom mov nyuaj thiab ua rau cem quav hauv cov miv cuam tshuam.
Nyob rau hauv cov miv, txoj hnyuv hauv plab yuav kav li ntawm 12 mus rau 24 teev los ntawm kev noj mus rau kev khiav tawm ntawm cov quav, thiab qee zaum tuaj yeem ua rau ntev yam tsis muaj kev phiv. Txawm li cas los xij, yog tias cov quav khaws cia ntev ntev, txoj hnyuv yuav muab dej los ntawm cov quav mus ntxiv mus txog thaum nws tsim cov tawv nqaij tawv thiab mob heev evacuated, ua rau cem quav. Yog hais tias cem quav no ntev, cov quav tso zis ua rau lub plab loj heev thiab nws yuav poob lub peev xwm los cog lus, ua rau megacolon.
Vim li no, thaum ntsib tus miv nrog cem quav, qhov ua rau yuav tsum tau pom, vim tias tsis kho mob cem quav tuaj yeem ua rau megacolon.
Causes of megacolon in miv
Feem ntau ntawm megacolon hauv miv, nyob ib ncig ntawm 62%, yog idiopathic, uas yog, lawv tsis muaj qhov tshwm sim, tom qab los ntawm obstructive mob ntawm txoj hnyuv (24%), tsim los ntawm neurological puas (11%).), congenital los yog los ntawm lwm yam ua rau ua rau cem quav nyob rau hauv miv.
Idiopathic megacolon
Megacolon no feem ntau tshwm sim nyob rau hauv cov laus txiv neej miv tshaj 8 xyoo nyob rau hauv uas tsis muaj cov kab mob organic. Nws ntseeg tau tias nws yuav yog vim yog thawj cov neuromuscular degeneration ntawm cov leeg nqaij ntawm txoj hnyuv, uas ua rau cem quav thiab tom qab megacolon. Nws raug kuaj pom los ntawm qhov tsis suav nrog lwm qhov laj thawj.

- Neuromuscular alterationvim sacro-coccygeal trauma.
Congenital megacolon
Qee zaum megacolon tshwm sim nyob rau hauv kittens, tuaj txog rau kev sab laj nyob rau hauv lawv thawj lub lim tiam ntawm lub neej vim mob fecal retention. Hauv cov xwm txheej no, nws feem ntau tshwm sim los ntawm cov kab mob hauv qab no:
- Aganglionosis: tsis muaj contraction-inhibiting neurons, uas ua rau cov leeg nqaij du ntawm txoj hnyuv los yog qhov quav, ua rau muaj kev cuam tshuam thiab megacolon.
- Nyob hauv Manx miv, vim yog ib feem los yog tsis tiav ntawm caudal thiab sacral spinal segment.
Megacolon vim cem quav heev
Thaum kawg, megacolon tuaj yeem tshwm sim los ntawm cem quav ntev vim:
- Stress/fearvim txav mus los, kho dua tshiab, qhia lwm tus tsiaj, kev hloov hauv chaw ua yeeb yam, pw hauv tsev kho mob, tsis ua haujlwm lossis kev tawm tsam rau lub tais ntawm xuab zeb. Yog xav paub ntxiv, tsis txhob nco lwm tsab xov xwm ntawm Kev Nyuaj Siab hauv miv.

- Hard tubular mass thoob plaws hauv plab palpation.
- Qee zaum diarrhoea, qee zaum muaj ntshav thiab hnoos.
Diagnosis of megacolon in miv
Megacolon yuav tsum tau kuaj pom los ntawm kev siv ntau yam kev kuaj mob yam tsis tau saib xyuas cov keeb kwm kev kho mob zoo, anamnesis thiab kev kuaj mob dav dav ntawm tus miv kom ntsuas nws lub xeev ntawm kev noj qab haus huv, dej dej, lub cev thiab lub hlwb, thaum tau txais cov ntaub ntawv hais txog qhov ua tau los yog ua rau uas ua rau cem quav ntev vim megacolon. Yuav tsum ua
Cov txheej txheem kuaj mob ntawm kev xaiv rau kev kuaj mob ntawm megacolon hauv miv yog abdominal radiography Nrog cov txheej txheem imaging no dhau pelvic canal strictures thiab masses tuaj yeem txiav txim tau. Nrog radiography nws kuj tuaj yeem sib txawv ntawm qhov mob hnyav heev los ntawm kev sib piv qhov sib piv ntawm qhov tuab ntawm txoj hnyuv loj thiab qhov ntev ntawm lub cev L5:
- A ratio <1.28 is an indicator of a normal colon.
- A piv ntawm 1.28-1.48 qhia cem quav.
- A ratio >1.48 good indicator of megacolon
- A ratio >1.6 is diagnostic of megacolon
Lwm yam kev yees duab muaj txiaj ntsig rau kev kuaj mob tuaj yeem yog abdominal ultrasound, colonoscopythiab magnetic resonance imaging, tshwj xeeb tshaj yog rau cov mob ntawm obstructive megacolon.
Thiab rau megacolon hauv miv
Kev kho mob ntawm feline megacolon yuav tsum combine dietary therapy with medical therapy los ntawm kev siv tshuaj thiab cov khoom uas pab txhawb kev tawm ntawm cov quav Qee zaum, kev kho phais yuav tsim nyog.
Feline megacolon noj tshuaj kho mob
Kev noj zaub mov rau miv nrog megacolon yuav tsum muaj cov dej noo ntau, ua kom cov dej hauv cov khoom noj los ntawm kev siv wet tiav zaub mov, cov khoom noj ntub dej xws li mis nyuj rau cov miv laus lossis cov kua zaub (tseem haum rau miv), ntxiv rau ntxiv dej rau cov zaub mov qhuav nrog pub.
Nws kuj yog ib qho kev xaiv zoo rau ntxiv insoluble fibers xws li Pysillium, uas ua rau cov dej ntau ntxiv ntawm cov quav thiab zaus. ntawm defecation. Txawm li cas los xij, lawv ntxiv ntau rau cov quav, uas tuaj yeem ua rau lub plab puas lawm, yog li lawv yuav tsum tau muab tsuas yog thaum ntxov ntawm tus kab mob thiab hauv cov miv uas muaj dej zoo.
kho mob ntawm feline megacolon
Yog tias koj xav paub yuav ua li cas kho megacolon hauv miv, koj yuav tsum paub tias tus kws kho mob tshwj xeeb yuav tsum tau sau cov tshuaj tsim nyog. Yog li, kev kho mob los kho feline megacolon thaum noj zaub mov tsis txaus yog siv cov pab pawg hauv qab no:
- Laxatives: ntxiv thaum hloov kev noj haus tsis txaus. Lactulose tuaj yeem siv tau ntawm ib koob ntawm 0.5 ml / kg txhua 8-12 teev, polyethylene glycol 3350 (Movicol Pediatric hmoov rau kev daws®) ntawm koob tshuaj 1/8 txog 1/4 teaspoon, txhua 12 teev ntawm cov zaub mov lossis bisacodyl (Dulcolaxo 5 mg) ntawm ib koob ntawm 5 mg / 24 teev ntawm qhov ncauj. Lawv txhawb cov mucosal secretion thiab colonic contractility, tab sis txuas ntxiv siv yuav ua rau enteric neurons
- Prokinetics xws li ranitidine tuaj yeem pab tau, tab sis ib zaug cov quav hauv cov quav raug kho kom txhawb cov plab hnyuv loj.
- Enemas: txhawm rau ua kom cov quav tso quav los ntawm kev qhia cov kua dej uas yooj yim rau kev nkag mus, xws li 5 mL ntawm lauryl sulfoacetate (Micralax ®) lossis bisacodyl (Dulcolaxo suppositories ®) hauv cov mob me. Yog tias qhov mob hnyav heev, enemas yuav tsum tau siv los ntawm lub tshuab nqus dej zoo 10-12 Fabkis txoj dej sov (5-10 ml / kg) nrog xab npum me me lossis roj ntxhia (5-10 ml / miv) (Hodernal®) los yog lactulose (5-10 ml / miv) (Duphalac syrup®).
- Manual extraction: Cov txheej txheem no tsuas yog ua rau cov mob hnyav heev thiab ib txwm nrog tus miv feem ntau tshuaj loog thiab hydrated. Tom qab kev tswj hwm ntawm ib qho enema, cov quav yog manipulated los ntawm lub plab phab ntsa los yog los ntawm qhov quav. Qhov no tuaj yeem ua rau cov mucosa ntawm txoj hnyuv loj tuaj yeem ua rau muaj kev pheej hmoo ntawm kev nqus cov co toxins thiab cov kab mob mus rau hauv cov ntshav, yog li cov tshuaj tua kab mob prophylactic yuav tsum tau noj txhua hnub.
Kev kho mob ntawm feline megacolon
Thaum tus miv raug kev txom nyem los ntawm megacolon, kev phais hu ua ' subtotal colectomy' tuaj yeem ua tau, uas muaj kev tshem tawm ntawm 95 - 85% txoj hnyuv loj thiab muaj feem ntau pom zoo. Cov quav tej zaum yuav ua kua thaum xub thawj tom qab phais, tab sis txhim kho hauv 1 mus rau 6 lub lis piam yog tias koj tsis muaj lwm yam kab mob uas ua rau raws plab, xws li kab mob plab hnyuv loj (SIBO) lossis kab mob plab hnyuv (IBD).
