Ma colonoscopy enieni

Virtual colonoscopy (VC) ndi kuyesa kapena kuyesa x-ray komwe kumayang'ana khansa, polyps, kapena matenda ena m'matumbo akulu (colon). Dokotala dzina la mayeso awa ndi CT colonography.

VC ndiyosiyana ndi colonoscopy yanthawi zonse. Nthawi zonse colonoscopy imagwiritsa ntchito chida chotalika, chowala chotchedwa colonoscope chomwe chimayikidwa m'matumbo ndi m'matumbo akulu.

VC imachitika mu dipatimenti ya radiology pachipatala kapena kuchipatala. Palibe zotsekemera zomwe zimafunikira ndipo palibe colonoscope yomwe imagwiritsidwa ntchito.

Kuyesaku kwachitika motere:

• Mumagona kumanzere kwanu patebulo locheperako lomwe limalumikizidwa ndi makina a MRI kapena CT.
• Mawondo anu ali pafupi ndi chifuwa chanu.
• Tepu yaying'ono yosinthasintha imalowetsedwa mu rectum. Mpweya umaponyedwa kudzera mu chubu kuti chithunzicho chikhale chachikulu komanso chosavuta kuwona.
• Kenako mumagona chagada.
• Gome limalowa mumtsinje waukulu mu makina a CT kapena MRI. Ma X-ray amtundu wanu amatengedwa.
• Ma X-ray amatengedwanso mutagona m'mimba.
• Muyenera kukhala chete munthawiyi, chifukwa kuyenda kumatha kusokoneza ma x-ray. Mutha kupemphedwa kuti musunge mpweya wanu pang'ono x-ray ikamatengedwa.

Kompyutayi imaphatikiza zithunzi zonse kuti apange zithunzithunzi zazithunzi zitatu za m'matumbo. Dokotala amatha kuwona zithunzizi pa kanema kanema.

Matumbo anu ayenera kukhala opanda kanthu komanso oyeretsa mayeso. Vuto m'matumbo anu akulu omwe amafunika kuthandizidwa atha kusowa ngati matumbo anu sanatsukidwe.

Wothandizira zaumoyo wanu adzakupatsani njira zoyeretsera matumbo anu. Izi zimatchedwa kukonzekera matumbo. Njira zingaphatikizepo:

• Kugwiritsa ntchito enemas
• Osadya zakudya zolimba kwa masiku 1 kapena 3 mayeso asanayesedwe
• Kutenga mankhwala otsekemera

Muyenera kumwa zakumwa zambiri zomveka kwa masiku 1 kapena 3 mayeso musanayesedwe. Zitsanzo zamadzimadzi omveka ndi awa:

• Chotsani khofi kapena tiyi
• Bouillon wopanda mafuta kapena msuzi
• Gelatin
• Zakumwa zamasewera
• Madzi osakaniza zipatso
• Madzi

Pitirizani kumwa mankhwala anu pokhapokha dokotala atakuuzani.

Muyenera kufunsa omwe akukuthandizani ngati mukufuna kusiya kumwa mapiritsi azinyalala kapena zakumwa masiku angapo mayeso asanayesedwe, pokhapokha ngati wopezayo angakuwuzeni kuti zili bwino. Iron imatha kupangitsa chopondapo chanu kukhala chakuda. Izi zimapangitsa kuti zikhale zovuta kuti dokotala awone mkati mwa matumbo anu.

Makina a CT ndi MRI ali ndi chidwi kwambiri ndi zitsulo. Osamavala zodzikongoletsera patsiku la mayeso anu. Mudzafunsidwa kuti musinthe zovala zanu za mumsewu ndi kuvala zovala zachipatala pochita izi.

Ma x-ray samva kuwawa. Kupopera mpweya mumatumbo kungayambitse kupweteka kapena kupweteka kwa mpweya.

Pambuyo pa mayeso:

• Mutha kudzimva kukhala otupa komanso kukhala ndi nkhawa m'mimba ndikudutsa mpweya wambiri.
• Muyenera kubwerera kuzomwe mumachita nthawi zonse.

VC itha kuchitika pazifukwa izi:

• Kutsata khansa ya m'matumbo kapena tizilombo tating'onoting'ono
• Kupweteka m'mimba, kusintha kwa matumbo, kapena kuwonda
• Kuchepa kwa magazi chifukwa chachitsulo chochepa
• Magazi pamalopo kapena akuda, malo odikira
• Sewero la khansa ya m'matumbo kapena m'matumbo (liyenera kuchitika zaka zisanu zilizonse)

Dokotala wanu angafune kuchita colonoscopy yokhazikika m'malo mwa VC. Cholinga chake ndikuti VC siyilola kuti dokotala achotse minofu kapena ma polyps.

Nthawi zina, VC imachitika ngati dokotala sanathe kusuntha chubu chosunthira kudzera m'matumbo nthawi zonse.

Zomwe zapezedwa ndizithunzi zamatumbo athanzi.

Zotsatira zosayembekezereka zitha kutanthauza izi:

• Khansa yoyipa
• Zikwama zachilendo pamatumbo, zotchedwa diverticulosis
• Colitis (matumbo otupa komanso otupa) chifukwa cha matenda a Crohn, ulcerative colitis, matenda, kapena kusowa kwa magazi
• Kutuluka m'munsi m'mimba (GI)
• Tinthu ting'onoting'ono
• Chotupa

Nthawi zonse colonoscopy itha kuchitika (tsiku lina) pambuyo pa VC ngati:

• Palibe chifukwa chakutaya magazi kapena zizindikilo zina zomwe zidapezeka.VC imatha kuphonya mavuto ang'onoang'ono m'matumbo.
• Mavuto omwe amafunikira biopsy adawonedwa pa VC.

Zowopsa za VC ndizo:

• Kuwonetsedwa ndi radiation kuchokera ku CT scan
• Nsautso, kusanza, kuphwanya, kapena kupsa mtima kwapadera kuchokera kumankhwala omwe amagwiritsidwa ntchito kukonzekera mayeso
• Kuwonongeka kwa m'matumbo pomwe chubu lopopera mpweya limalowetsedwa (ndizokayikitsa kwambiri).

Kusiyanitsa pakati pa colonoscopy yodziwika bwino ndi monga:

• VC imatha kuwona colon m'makona osiyanasiyana. Izi sizophweka ndi colonoscopy yanthawi zonse.
• VC siyenera kukhala pansi. Mutha kubwereranso kuzomwe mumachita mukangoyesedwa. Nthawi zonse colonoscopy imagwiritsa ntchito sedation ndipo nthawi zambiri kutayika kwa tsiku logwira ntchito.
• VC yogwiritsa ntchito makina a CT imakuwonetsani ku radiation.
• Nthawi zonse colonoscopy imakhala ndi chiopsezo chochepa chazakudya zam'mimba (zopangira misozi yaying'ono). Palibe chiopsezo chotere kuchokera kwa VC.
• VC nthawi zambiri siyitha kudziwa tizilombo tating'onoting'ono tating'ono kuposa 10 mm. Nthawi zonse colonoscopy imatha kudziwa mitundu yambiri yamitundu yonse.
