Ukuhlinzwa kokuhlukaniswa kabili (for twins conjoined) kuvame ukushaya izindaba, ezibandakanya odokotela namahora amaningi. Uke waba nesifiso sokuthi impela ukuhlinzekwa okufana nalokhu kufaka phakathi?
Ukuqonda amawele ahlangene
Ukuhlinzwa kokuhlukana kwe-Twin kwenzeka lapho odokotela behlukanisa amawele abazalwa ngokuhlanganyela ngesikhathi sokuzalwa. Amawele ahlangene ahlangene ndawonye, kokubili ngaphakathi emzimbeni wabo ngokuhlanganyela izitho ezithile noma izingxenye zomzimba, kanye nangaphandle kwesikhumba.
Ngokuvamile amawele afanayo, okusho ukuthi azoba ngesondo esifanayo. Amawele ahlangene empeleni ayalwa kakhulu, acatshangwa ukuthi angaba ngu-1 kuma-50,000 kuya ku-100,000 amawele emhlabeni jikelele.
Uma amazinyane amabili amawele ehlanganiswa ndawonye endaweni efanayo, abizwa ngokuthi amawele ahlangene. Kwezinye izimo, elinye lamawele ahlangene kungenzeka ukuthi aliphili futhi libizwa ngokuthi "ama-parasitic" amawele. Omunye amawele angase akhuliswe futhi akwazi ukuhlala ngaphandle kwesibeletho, kanti amanye amawele angathuthuki kahle ukuze aqhubeke nokuphila.
Amawele amancane angama-twins angama-symmetrical, kuyilapho ama-fetus abesilisa ejwayele ukuba namacala amaningi amawele angama-parasitic. Nakuba odokotela bengacaciseki ukuthi kungani, amawele amakhosikazi ahlangene nawo athambekele ekubeni nethuba eliphakeme lokusinda. Ngezinye izikhathi, zombili amawele angase ahambisane nokuphila ngenxa yokuthuthukiswa okungavamile nokuhlanganiswa. Amawele ahlangene, uma esinda, asemngciphekweni wezinkinga eziningi zezempilo nezinkinga.
Iyini Ukuhlinzwa Okwehlukaniswa Okwesithathu?
Ukuhlinzwa kwe-twwin yokuhlukanisa amawele ahlangene kungaba okuhlukile, kuye ngokuthi amawele ahlangene kanjani. Isibonelo, amanye amawele angabelana nge-digestive tract noma ingxenye yesistimu yabo yokujikeleza. Uhlelo oluyinkimbinkimbi yesimiso esithintekile, ukuhlinzwa kungase kube nzima.
Ngokusho kweYunivesithi yaseMalnandan, kunezigaba ezingaba ngu-12 ezihlukene zamawele ezihlangene ezizocacisa ukuthi yiyiphi inqubo yokuhlinzwa edingekayo. Amawele angaboshwa emizimbeni yawo engaphezulu futhi abelane ngenhliziyo, okwenza kube nzima ukwenza umsebenzi ophumelelayo. Ezinye izinhlobo zamawele zingabelana nomzimba ophezulu nezitho ezithile, njenge-isibindi noma i-GI ipheshana, kodwa hhayi inhliziyo, okwenza ukuhlinzwa kube inketho engokoqobo. Uhlobo oluhlukumezayo lwamathanga ahlangene ngama-craniopagus amawele, axhunyiwe ekhanda.
Ngokwemlando, ukuhlinzwa kokubili kwamawele kwakungeyona inketho futhi amawele ahlangene awakhulelwa ahlala ehlangene kuwo wonke ukuphila kwawo. Isibonelo, esinye sezintambo ezidume kakhulu zamawele kwakuyi-Eng no-Chang Bunker. Abazalwane bazalwa eThailand, ebizwa ngokuthi "uSiam," ngo-1811, nokuthi iqiniso lokuthi bahlala bahlangane ekugcineni baholela ekutheni igama elithi "amawele e-Siamese." Nokho, lelo gama alisetshenzisiwe njengamawele angama-conjoined ahlobene nendawo lapho izingane zizalwa khona.
Uyini Umphumela Wokuhlinzwa Okwehlukaniswa Kwababili?
Umphumela wokuhlinzwa kokuhlukana kwamabili kuzoxhomeka ukuthi amawele ahlangene kanjani nokuthi kuphi. Ngeshwa, udokotela akakwazi ukutshela izinga lokuhlanganiswa kuze kube yilapho abantwana bezalwa, ngakho-ke noma yikuphi ukukhetha kanye nemininingwane ethile mayelana nokuthi yiluphi uhlobo lokuhlinzwa oludingekayo kufanele ulinde kuze kube sekuzalweni kwezingane.
Esinye isifundo esilandela amawele angu-14 ahlukaniswe ukuhlinzwa ngemva kokubeletha, amafa amabili amawele ayenamaviki amabili asinda futhi lawo mafa amabili amane adingeka okungaphezu kokuhlinzwa okulodwa ngaphambi kokuqedwa kokuqedwa. Kodwa-ke, wonke amawele ezitsheni ezisaphila alandelwa odokotela futhi wabonisa ukuthuthukiswa okufanele nokujwayelekile. Nakuba kwezinye izimo, amawele ahlukaniswe angadinga usizo olwengeziwe noma ukwelashwa emithonjeni yabo ikakhulukazi, njengoba abaningi babo bengabumba kahle.
Njengoba ubuchwepheshe buqhubekile, amawele amaningi ahlangene akwazi ukuzuza ekuhlinzekeni kwamawele amabili ngaphandle kokubhekana nezinkinga ezinkulu.
