Igama elithi "fat necrosis" lisho i-focal necrosis yezicubu ze-adipose ngenxa yesenzo sezici ezihlukahlukene. I-fat necrosis yenzeka kumanyikwe, kuzicubu ze-adipose retroperitoneal, phakathi kwamafutha e-omentum, i-mesentery, kuzicubu ezinamafutha ze-mediastinum, kumafutha e-epicardial, kungqimba lwamafutha ngaphansi kwe-parietal pleura, ku-subcutaneous fat fat and emnkantsheni.
Ukwakheka kwe-anatomical yama-pendants kukholoni ye-sigmoid kuphakamisa i-volvulus yabo kanye nokuthuthukiswa kokuvuvukala kanye ne-necrosis. Imbangela ye-suspension volvulus ingase iwadayise ku-parietal peritoneum noma ezinye izitho. Ukuhlolwa okuningi kwabantu asebekhulile abaphethwe ukuqunjelwa kuye kwaholela esiphethweni sokuthi ikholoni yabo ye-sigmoid ikhulisiwe ngosayizi ngakho-ke amapende anamafutha acindezelwa odongeni lwangaphambili lwesisu.
Imisipha yodonga lwangaphambili lwesisu, ngenxa yezinguquko ze-hypotrophic, inama-hernias ezindaweni ezisengozini kakhulu, ukumiswa okunamafutha onqenqemeni lwamahhala lwekholoni ye-sigmoid kuwela ekucindezelekeni noma ku-fossa ye-parietal peritoneum, ivuvuke futhi ithengiswe kuyo. Ngemuva kwalokho, i-necrosis ingakhula.
Kunezinhlobo eziningana ze-fat necrosis
· I-Enzymatic fat necrosis kuwumphumela we-pancreatitis eyingozi kanye nokulimala kumanyikwe, kwakheka lapho ama-enzyme e-pancreatic ephuma emiseleni engena ezicutshini ezizungezile. I-pancreatic lipase iphula ama-triglycerides kumaseli amafutha abe yi-glycerol namafutha acid, abuye ahlangane nama-ion e-plasma calcium enze insipho ye-calcium. Ama-plaque amhlophe, aminyene namaqhuqhuva avela kuzicubu ze-adipose. Uma i-lipase ingena egazini, khona-ke i-fat necrosis ingatholwa ezindaweni eziningi zomzimba.
· I-non-enzymatic fat necrosis kutholakala ku-mammary gland, izicubu ze-adipose ezingaphansi kwesikhumba kanye nasemgodini wesisu, kubizwa ngokuthi i-traumatic fat necrosis. Kubangela ukwanda kwenani lama-macrophages ane-foamy cytoplasm, neutrophils nama-lymphocyte. Inqubo yokwakheka kwezicubu ezixhumeneyo (fibrosis) ingase yenzeke, ngokuvamile iphutha ngokwakhiwa kwesimila.
Kuyaziwa ukuthi i-fat necrosis ayiguquki ibe isimila esiyingozi, kodwa ingayilingisa. I-fatty necrosis ye-mammary gland ivela ngenxa yokuhlukumezeka, ngenxa yalokho imikhumbi emincane yonakaliswa, ukunikezwa kwegazi kulahleka. Le pathology ingenzeka ngesikhathi sokwelashwa ngemisebe, ngokuncipha okusheshayo kwesisindo.
Lesi sifo singaqhubeka ngaphandle kobuhlungu noma ngokuzwa ubuhlungu ku-palpation. Ibonakala ngokwanda kwama-lymph nodes kanye nokwakheka kwama-dimples esikhumbeni. Ukwelashwa kuhlanganisa ukususa ukugxila kwe-fat necrosis ngokukhishwa kwengxenye.
Isifo sokuvuvukala noma i-necrosis yezicubu ze-adipose ezingaphansi kwesikhumba zenzeka ikakhulukazi ezinganeni ezisanda kuzalwa.
Kuze kube manje, izizathu azikacaciswa. Indawo eyinhloko ye-pathology ibonakala ezinqeni, emathangeni, emhlane, ezingalweni ezingaphezulu nasebusweni. Ukwakheka kwale nqubo kwandulelwa ukuvuvukala okuminyene kwesikhumba. I-Necrosis kulokhu ingagxila noma isakazeke. Kunqunywa ukuba khona kwama-node abuhlungu ombala wesikhumba noma obomvu nge-purple tint kanye nesimo esingavamile.
Ezindaweni zezilonda, ukungathathi hlangothi okungahleliwe kwezenzakalo ze-pathological kungenzeka, lapho kungekho mkhondo osele. Uma ama-salts e-calcium akhiwa endaweni ethintekile yi-necrosis, khona-ke okuqukethwe kwe-liquid kuphuma, bese kuba nezibazi ezincane. Ezimweni ezingavamile, izimpawu ezilandelayo zingenzeka: ukwehlisa umfutho wegazi, ukukhathala, ukuhlanza kanye nezimo zokushisa.
Ihlaziya isho ukwanda kokugcwala kwe-calcium ku-plasma yegazi kanye nezinga eliphakeme ngokungavamile le-lipids. I-fat necrosis ezinganeni ikhula ngenxa yokulimala kokuzalwa, i-asphyxia, ithonya lamazinga okushisa aphansi noma ukwehla kokushisa komzimba okuyisisekelo. Ocwaningweni, izinguquko ze-histological zibaluleke kakhulu, zivezwa ngokujiya kwe-fibrous septa, ukufakwa kwamakristalu ngaphakathi kwamaseli amafutha kanye nokungena kwamaseli e-granulomatous.
Lesi sifo sizenzakalela, ngakho-ke ukwelashwa akudingeki, akufanelekile ukufisa ngenaliti kusuka ezintweni zesikhumba ezishintshayo, lokhu kungabangela ukutheleleka, bese kuba nezinkinga ezingalindelekile. Kukhona futhi necrosis yezicubu ze-adipose, lapho izicubu ze-adipose ezizungeze amalunga ziba necrotic.
Kulesi simo, izinga lokushisa lomzimba lihlala likhuphuka, isifo samathambo sikhula, futhi amalunga ayabhujiswa. I-necrosis esakazwayo yezicubu ze-adipose nayo ivela eqinisweni lokuthi ama-enzyme e-pancreatic angena egazini noma i-lymph. Izinga lokufa kulolu hlobo lwe-adipose tissue necrosis liphezulu kakhulu, kufanele uhlale ukhumbula ukuthi kufanele ubike noma yiziphi izimpawu zempilo embi kudokotela wakho. Ukunakekelwa kwezokwelapha okufika ngesikhathi kuphela kunomthelela ekulondolozweni kwempilo.
