Lo lus "fat necrosis" txhais tau hais tias focal necrosis ntawm cov ntaub so ntswg adipose vim kev ua ntawm ntau yam. Cov rog necrosis tshwm sim hauv pancreas, nyob rau hauv cov ntaub so ntswg retroperitoneal adipose, ntawm cov rog ntawm omentum, mesentery, nyob rau hauv cov nqaijrog ntawm mediastinum, nyob rau hauv lub epicardial rog, nyob rau hauv cov rog txheej nyob rau hauv lub parietal pleura, nyob rau hauv lub subcutaneous fatty ntaub so ntswg. hauv cov pob txha.
Lub anatomical qauv ntawm cov pendants nyob rau hauv cov hnyuv sigmoid qhia lawv volvulus thiab kev loj hlob ntawm o thiab necrosis. Qhov ua rau raug tshem tawm volvulus tuaj yeem ua rau lawv mus rau parietal peritoneum lossis lwm yam kabmob. Ntau qhov kev ntsuam xyuas ntawm cov neeg laus raug kev txom nyem los ntawm cem quav tau ua rau kev txiav txim siab tias lawv cov nyuv sigmoid loj tuaj thiab yog li ntawd cov roj ntsha pendants raug nias tawm tsam phab ntsa sab hauv plab.
Cov nqaij ntshiv ntawm lub plab anterior, vim yog kev hloov pauv ntawm hypotrophic, muaj hernias nyob rau hauv qhov chaw muaj kev cuam tshuam tshaj plaws, fatty suspensions ntawm dawb ntug ntawm sigmoid nyuv poob rau hauv kev nyuaj siab los yog fossa ntawm parietal peritoneum, ua mob thiab soldered rau nws. Tom qab ntawd, necrosis tuaj yeem tshwm sim.
Muaj ntau hom rog necrosis
· Enzymatic rog necrosis yog qhov tshwm sim ntawm tus mob pancreatitis thiab kev puas tsuaj rau tus txiav, yog tsim thaum pancreatic enzymes tawm hauv cov ducts mus rau hauv cov ntaub so ntswg. Pancreatic lipase rhuav tshem triglycerides hauv cov rog rog rau hauv glycerol thiab fatty acids, uas ua rau muaj kev cuam tshuam nrog cov ntshav calcium ions los tsim cov calcium xab npum. Dawb, ntom plaques thiab nodules tshwm nyob rau hauv cov ntaub so ntswg adipose. Yog tias lipase nkag mus rau hauv cov hlab ntsha, cov roj necrosis tuaj yeem kuaj pom hauv ntau qhov chaw ntawm lub cev.
· Tsis-enzymatic rog necrosis kuaj pom nyob rau hauv cov qog mammary, cov ntaub so ntswg subcutaneous adipose thiab nyob rau hauv lub plab kab noj hniav, nws yog hu ua traumatic fat necrosis. Nws ua rau muaj qhov nce ntawm cov macrophages nrog foamy cytoplasm, neutrophils thiab lymphocytes. Cov txheej txheem ntawm kev tsim cov ntaub so ntswg (fibrosis) tuaj yeem tshwm sim, feem ntau yuam kev rau kev tsim cov qog.
Nws paub tias rog necrosis tsis hloov mus rau hauv cov qog nqaij hlav, tab sis tuaj yeem simulate nws. Fatty necrosis ntawm lub caj pas mammary tshwm sim los ntawm kev raug mob, raws li qhov tshwm sim ntawm cov hlab ntsha me me, cov ntshav poob. Cov kab mob no tuaj yeem tshwm sim thaum kho hluav taws xob, nrog kev poob phaus sai.
Tus kab mob tuaj yeem mus tsis mob lossis hnov mob ntawm palpation. Nws yog tus cwj pwm los ntawm kev nce hauv cov qog ntshav qog thiab tsim cov dimples ntawm daim tawv nqaij. Kev kho mob muaj nyob rau hauv kev tshem tawm qhov tseem ceeb ntawm cov rog necrosis los ntawm sectoral resection.
Inflammatory kab mob los yog necrosis ntawm subcutaneous adipose ntaub so ntswg tshwm sim nyob rau hauv cov me nyuam mos.
Txog niaj hnub no, cov laj thawj tseem tsis tau qhia meej. Lub ntsiab localization ntawm pathology yog pom ntawm pob tw, ncej puab, nraub qaum, sab caj npab thiab lub ntsej muag. Kev tsim ntawm cov txheej txheem no yog ua ntej los ntawm qhov ntom ntom ntom ntawm daim tawv nqaij. Necrosis nyob rau hauv cov ntaub ntawv no yuav ua tau focal los yog dav. Nws yog txiav txim los ntawm lub xub ntiag ntawm qhov mob ntawm daim tawv nqaij xim los yog reddish nrog ib tug liab doog tint thiab irregular duab.
Nyob rau ntawm qhov chaw ntawm qhov txhab, arbitrary neutralization ntawm pathological phenomena tuaj yeem tshwm sim, los ntawm qhov tsis muaj kab nyob. Yog tias calcium ntsev tau tsim nyob rau hauv qhov chaw cuam tshuam los ntawm necrosis, cov kua dej tawm tuaj, thiab cov nti me me tuaj yeem tsim. Muaj tsawg zaus, cov tsos mob hauv qab no tuaj yeem ua tau: txo qis ntshav siab, qaug zog, ntuav thiab kub taub hau.
Kev tshuaj xyuas hais txog qhov nce ntawm cov calcium hauv cov ntshav plasma thiab nce qib ntawm lipids. Fat necrosis nyob rau hauv cov me nyuam loj hlob raws li ib tug tshwm sim ntawm kev yug me nyuam raug mob, asphyxia, cuam tshuam ntawm tsis kub los yog ib tug txo nyob rau hauv lub cev kub. Nyob rau hauv txoj kev tshawb no, histological kev hloov pauv tseem ceeb heev, qhia los ntawm thickening ntawm fibrous septa, deposition ntawm crystals nyob rau hauv cov roj hlwb thiab granulomatous cell infiltrates.
Tus kab mob no tshwm sim, yog li kev kho mob tsis tas yuav tsum tau, nws tsis pom zoo kom aspirate nrog ib rab koob los ntawm cov tawv nqaij hloov pauv, qhov no tuaj yeem ua rau muaj kab mob, thiab tom qab ntawd cov teeb meem tsis tau pom dua tuaj yeem ua tau. Kuj tseem muaj cov ntaub so ntswg adipose necrosis, qhov twg cov ntaub so ntswg adipose nyob ib ncig ntawm cov pob qij txha ua necrotic.
Hauv qhov no, lub cev kub ib txwm nce, mob caj dab tsim, thiab cov pob qij txha raug puas tsuaj. Disseminated necrosis ntawm cov ntaub so ntswg adipose kuj tshwm sim los ntawm qhov tseeb tias pancreatic enzymes nkag mus rau hauv cov ntshav lossis lymph. Tus neeg tuag nyob rau hauv hom adipose nqaij necrosis yog siab heev, koj yuav tsum nco ntsoov tias koj yuav tsum qhia cov tsos mob ntawm kev noj qab haus huv tsis zoo rau koj tus kws kho mob. Tsuas yog kev kho mob raws sij hawm xwb thiaj li ua rau muaj kev noj qab haus huv.
