Isigmoidoscopy

I-Sigmoidoscopy yinkqubo esetyenziselwa ukubona ngaphakathi kwe-sigmoid colon kunye ne-rectum. Ikholoni ye-sigmoid yindawo yamathumbu amakhulu akufutshane ne-rectum.

Ngexesha lovavanyo:

• Ulala ngecala lakho lasekhohlo amadolo ebotshelelwe esifubeni sakho.
• Ugqirha ubeka ngobunono igloved kunye ne-lubricated finger kwi-rectum yakho ukujonga ukuvalwa kwaye ngobunono yandisa (dilate) i-anus. Oku kubizwa ngokuba luvavanyo lwedijithali.
• Emva koko, i-sigmoidoscope ibekwe kwi-anus. Ubungakanani yityhubhu eguqukayo enekhamera ekupheleni kwayo. Ubungakanani buhanjiswe ngobunono kwikholoni yakho. Umoya ufakwa kwikholoni ukuze wandise indawo kwaye uncede ugqirha ajonge indawo ngcono. Umoya unokubangela umnqweno wokuba nokuhamba kwamathumbu okanye ukudlulisa igesi. Ukufunxa kunokusetyenziselwa ukususa ulwelo okanye isitulo.
• Rhoqo, imifanekiso iyabonakala kwinkcazo ephezulu kwisibuko sevidiyo.
• Ugqirha unokuthatha iisampulu zethishu ngesixhobo esincinci se-biopsy okanye umgibe wentsimbi omncinci ofakwe kwisikali. Ubushushu (i-electrocautery) bunokusetyenziselwa ukususa iipolyps. Iifoto zangaphakathi kwikholoni yakho zinokuthathwa.

I-Sigmoidoscopy isebenzisa umda oqinileyo unokwenziwa ukunyanga iingxaki ze-anus okanye i-rectum.

Umboneleli wakho wezempilo uza kukuxelela indlela yokulungiselela uviwo. Uya kusebenzisa i-enema ukukhupha amathumbu akho. Oku kuhlala kwenziwa kwiyure e-1 ngaphambi kwesigmoidoscopy. Rhoqo, i-enema yesibini inokucetyiswa okanye umboneleli wakho anokucebisa nge-laxative engamanzi kubusuku obungaphambili.

Ngentsasa yenkqubo, unokucelwa ukuba uzile ngaphandle kwamayeza athile. Qinisekisa ukuba uxoxa ngale nto kunye nomboneleli wakho kwangaphambili. Ngamanye amaxesha, uyacelwa ukuba ulandele ukutya okucacileyo kolwelo kusuku olungaphambili, kwaye ngamanye amaxesha ukutya okuqhelekileyo kuvunyelwe. Kwakhona, xoxa oku nomboneleli wakho kwangaphambi komhla wovavanyo lwakho.

Ngexesha loviwo unokuziva:

• Uxinzelelo ngexesha lovavanyo lwe-rectal rectal okanye xa ubungakanani bubekwe kwi-rectum yakho.
• Isidingo sokunyakaza kwamathumbu.
• Ukudumba okanye ukucofa okubangelwa ngumoya okanye ukolulwa kwamathumbu yisigmoidoscope.

Emva kovavanyo, umzimba wakho uya kudlulisa umoya obekwe kwikholoni yakho.

Abantwana banokunikwa iyeza lokubenza balale kancinci (behliswe) kule nkqubo.

Umboneleli wakho unokucebisa olu vavanyo ukukhangela unobangela woku:

• Intlungu zesisu
• Urhudo, ukuqhina, okanye olunye utshintsho kwimikhwa yamathumbu
• Igazi, i-mucus, okanye i-pus esitulweni
• Ukwehla kobunzima obungenakuchazwa

Olu vavanyo lunokusetyenziselwa:

• Qinisekisa ukufunyanwa kolunye uvavanyo okanye i-x-ray
• Isikrini somhlaza onobala okanye iipolyps
• Thatha i-biopsy yokukhula

Iziphumo zovavanyo eziqhelekileyo aziyi kubonisa ngxaki ngombala, ubunjani, kunye nobungakanani belining ye-sigmoid colon, i-rectal mucosa, i-rectum kunye ne-anus.

Iziphumo ezingaqhelekanga zingabonisa:

• Ukuqhekeka kwe-anal (ukwahlula okuncinci okanye ukukrazula kwithishu encinci, emanzi efake i-anus)
• Ithumba le-anorectal (ingqokelela yobofu kwindawo ye-anus kunye ne-rectum)
• Ukuvaleka kwamathumbu amakhulu (isifo seHirschsprung)
• Umhlaza
• Iipolyps Colorectal
• I-Diverticulosis (iipokethi ezingaqhelekanga kumgca wamathumbu)
• Iimpawu
• Ukudumba kwesifo
• Ukudumba okanye usulelo (proctitis kunye necolitis)

Kukho umngcipheko omncinci wokugcotshwa kwamathumbu (ukukrazula umngxunya) kunye nokopha kwiindawo ze-biopsy. Umngcipheko uwonke mncinci kakhulu.
