Lymph nodes zvivako zviduku zvakagadzirwa nenyuchi zviri mumuviri wose. Izvo zvikamu zve lymph system, mararamiro-akasiyana-siyana kune mutezo weropa wehutachiona. Lymph nodes inoshanda sechidiki chemasimba omumakungwa kunze kwemasango, anopararira pamwe chete nehurongwa hwemigero inopisa mvura kubva mumasumbu mune dzimwe nhengo dzomuviri.
Apo lymph nodes mune chimwe chikamu chemuviri unozivikanwa sekuti retroperitoneum yakawedzerwa, kune zvakawanda zvinokonzera zvinokonzera, kusanganisira zvinotevera:
- Zvirwere, zvakadai sechirwere chetachiona
- Kuvhiringidza kubva kune imwe nhamba yezvikonzero, kusanganisira zvirwere zvakadai sarcoidosis
- Kanzura kubva panzvimbo yakakura mumuviri inosangana nemasikirini
- Ropa rekenza rinowedzera mumakirinikodhi kana kupararira kune lymph nodes
- Zvimwe zvinokonzera zvisingaiti
Kune nguva dzose dzakasiyana-siyana dzakakonzera zvikonzero zvekuti chero nhengo ipi neipi yerymph node inodonha, uye kwete vose vane kenza. Ichokwadi, kana munhu achiona chiremba chekuremara kwema-lymph nodes, kenza haiwanzo chikonzero. Asi, hutachiona hwehutachiona hunowanzopomera mhosva-kunyanya kana lymph nodes dzakarema dziri pamutsipa. Zvisinei, kune dzimwe mhando dzemaitiro emakiromine nhengo dzisinganyanyi kuratidzira maitiro akaoma, akadai sekumhanya kukuru kwemakiromodhi akawedzerwa anoonekwa akabatanidzwa pamwe chete mukudzidza kwekufungidzira.
Retroperitoneal Lymph Nodes Inogona Kuwedzera mune Zvirwere Zvimwe
Retroperitoneal lymph nodes iri munzvimbo yavasingawanzoonekwa kana kuonekwa pavanotanga kuvhara, uye saka vanachiremba vangauya kuzodzidza nezvekuwedzera kwavo nenzira yekufungidzirwa kwekufungidzira kwakafanana neT CT scan yemimba nemapapu.
Dzimwe nguva retroperitoneal lymph nodes inowanzobatanidzwa nehutano iyo inobereka zviratidzo, sezvo zvivako zviri pedyo zvingakanganisa. Mune zvimwe zviitiko, zviratidzo zvinogona kutungamirira kuchidzidzo chekufungidzira chinoona retroperitoneal lymph node kuwedzera. Zvisinei, chikonzero chekudzivirira hachifaniri kuonekwa nyore nyore kubva pamagetsi ekufungidzira, uye bhiopsy yemakwenzi anowanzobatanidzwa anowanzodiwa.
Mune mhaka yevanhu vane simba rekudzivirira zvirwere, mamwe emakona ekuwedzera kwema-lrophitoneal lymph nodes ndiwo: hutachiona nemhando yebhakitiriya inonzi Mycobacterium; lymphoma, kenza yeropa inowanzotanga mumakirini emakumbo; uye Kaposi's sarcoma, kenza inowanzobva mumasero ayo anowedzera lymph kana mitsipa yeropa.
Apo lymph nodes yakakura yakaonekwa mune chimwe chikamu chemuviri chakadai se retroperitoneal, nzvimbo iyo inonyanya kujeka munguva, naizvozvo kune mikana yakasiyana maererano nehosha inenge iripo. Nodhi dzakawedzerwa dzinogona kunge dzichiri chikamu chekutanga chechirwere chichazopedzisira chichiratidza lymph node kuwedzera munzvimbo dzakasiyana dzomuviri kana kufambira mberi kwechiremera chinonzi lymphadenopathy syndrome.
Kana pane zvikamu zvakawanda zve lymph nodes zvinosanganisira retroperitoneum uye kuongorora kunoratidzawo chiropa chakawedzerwa uye spleen, izvi zvinogona kuva zvinokurudzira zve lymphoma , zvisinei, pane zvimwe zvingaita. Castleman chirwere chirwere chisingawanzo chinosanganisira lymph nodes. Mamwe mazita anosanganisira giant lymph node hyperplasia, uye angiofollicular lymph node hyperplasia. Dr. Benjamin Castleman akatanga kuzvitsanangura muma1950.
Chirwere chinonzi Castleman chinoonekwa sechirwere chechirwere chinonzi lymphoproliferative, zvinoreva kuti kune kukwira kwemasero e-lymph system.
Kunyange zvazvo isisiri kenza, inogona kufanana zvikuru ne lymphoma, uye mamwe maitiro anogona kukura kuva lymphoma.
Ndekupi Retroperitoneum uye Nei Zvine Basa?
Gross anatomy inosarudza zita reyine lymph nodes. Retroperitoneal lymph nodes inonzi lymph nodes inowanikwa mune imwe nzvimbo yemuviri, inonzi retroperitoneum. Iro retroperitoneum inotsanangura chikamu chemuviri wemimba-chikamu chemuviri chinowanzoswedera pedyo neshure mako kupfuura chinetso chako chemimba, kumashure shure kwemukati.
Retroperitoneal lymph nodes ndeimwe yemapoka akawanda emaronda anowanikwa mukati memuviri, sezvinoratidzwa munotevera urongwa:
- Retroperitoneal lymph nodes - inowanika mu retroperitoneum
- Inguin lymph nodes - inowanikwa munzvimbo inogomera
- Axillary lymph nodes - inowanikwa mumarmpits
- Mediastinal lymph nodes - inowanikwa mubhokisi, pedyo nemwoyo
Lymph nodes inogona kutumidzwa kunzvimbo ipi zvayo yemuviri kana kuti nhengo yakasiyana. Semuenzaniso, kune lymph node inowanikwa mumatare ari pedyo neaorta. Izvozvo zvinonzi lymph node zvingawanzoidzwa seytracic node. Kuva yakajeka, kana iri muimba iri pedo nemwoyo, inogonawo kuonekwa seyemukati wemakiriniki , kana kunyanya kunyanya, kana iri pedo neaorta, iyo yechipfupa inopera-yose iyo inenge ichinyora mazita, asi kushandiswa kwaizova kwakanyanya kunyanya.
Iro peritoneum inhengo inobatanidza dumbu remuviri uye inosanganisira nhengo dzemimba. Chimbofungidzira se 'bundu rakapetwa repurasitiki' rinoita kuti zvose zvinyongedzwe pachako panguva yekufambisa. Dzimwe nhengo dziri intraperitoneal, kana mukati me peritoneum, asi vamwe vari shure kwavo, kana retroperitoneal.
Retroperitoneal Organs
Chikonzero chekuwedzera kwe-lymph node dzimwe nguva chinoratidzika kune nhengo dziri pedo nodhi dzakawedzerwa. Nhengo dzinoverengeka dziri mukati me peritoneum uye vamwe vari muchidimbu mukati uye nechekunze kunze kwe peritoneum. Vadzidzi vanogona kushandisa chiyeuchidzo chinotevera chekuyeuka kuti vadzidze nhengo dzipi dziri retroperitoneal:
S: suprarenal kana adrenal gland
A: aorta / inferior vena cava
D: duodenum (yechipiri nechetatu chikamu)
P: pancreas (kunze kwemuswe wepancreas)
U: ureters
C: colon (ichikwira uye ichidzika)
K: itsvo
E: esophagus
R: rectum
Zvikamu zvinoteverwa nevabereki vevana zvinongodzokorora zvishoma nezvishoma. Dzimwe nguva chirwere chinokanganisa chimwe chezvikamu izvi chichatibatsirawo maitiro emakirini anoenderana uye pamwe chete. Semuenzaniso, vanorwara vanotakura urinha kubva kuinso kusvika kune chidimbu, uye masasa munzvimbo ino anogona kudzivisa ureter, zvichikonzera zviratidzo zvekuvhenekera. Retroperitoneal lymphadenopathy kazhinji haibereki zviratidzo, asi zvirwere zvakakura zvinogona kutungamirira kumakumbo asinganzwisisi kana kuvhiringidzwa kwemvura.
Retroperitoneal Lymph Nodes muLymphoma
Lymphomas iboka rekenza ye lymph system . Lymphomas inowanzotanga mu lymph nodes, uye retroperitoneal lymph nodes inokanganiswa mune mishonga yakawanda.
Kune zvikamu zviviri zvakakura zve lymphoma:
1) Hodgkin's lymphoma, kana HL- uye pano ndiyo hukama huri kuHodgkin's.
2) Hasi-Hodgkin's lymphoma, kana NHL iyo inowedzera anenge 90 muzana yemaronda ose, inowanikwa nemhando dzakawanda kupfuura Hodgkin's lymphoma.
Zvose HL neNHL zvinogona kukonzera retroperitoneal lymph node kupinda. Kunyange zvazvo HL inowanzopararira mune imwe nzira yakatsanangurwa, kubva kune rimwe rymph node boka kusvika kune rinotevera, NHL inogona kusimuka uye inosanganisira kuisa mapoka akasiyana emakirini, izvo zvinosanganisira retroperitoneal lymph nodes, panguva yekuratidzwa.
Retroperitoneal Lymph Nodes mune dzimwe Kankere
Zvimwe zvirwere zvekenza zvinogonawo kugadzirisa zvirwere zvekudzivirira zvinonzi lymph nodes. Chimwe chekenza iyi ndeyechirwere chekenza. Kanzera yechipupuriro inowanzopararira mumutambo unofanirwa kuburikidza nemakirini ekutora (retroperitoneal lymph nodes (RPLN), uye mune dzimwe nguva, chirwere chinonzi retroperitoneal lymph node dissection (RPLND) chakaitwa. Imwe nzira inogona kuitika yekuvhiya iyi inodzorerazve kudii. Kana chirwere ichi chichichera chirwere panguva yekuvhiyiwa, kuwedzerwa kunogona kuitika, asi chirume chinopedzisira chiri mukanyoka, uye naizvozvo kusununguka inetso.
Shoko Rinobva
Apo lymph nodes yakakura mu retroperitoneum inoratidzika, kukosha kwekuwana uku kunobva kune dzimwe dzose zveruzivo, kusanganisira nhoroondo yezvechiremba yemunhu ane nodes akawedzerwa. Chimwe chinhu chinonyanya kukoshesa nodes yakakura munzvimbo ino chaiyo ndeyekuti ivo vari kure zvakanyanya kubva kune imwe yose yomuviri uye haisi nyore nyore kuonekwa se lymph nodes mumutsipa, mazamu kana kugomera, somuenzaniso.
Dzimwe nguva lymph nodes "muganhu-yakawedzerwa" pamafungiro, zvichireva kuti zvishoma kudarika zvinowanzoitika, asi kwete chaizvoizvo chikonzero chekufunganya. Mune zviitiko izvi, pangava nekufungidzira kwekutevera kwakaitwa uye kuenzanisa nekuongorora kwekare kuti uone kana kune kuve nekuwedzerwa mukati.
Nguva dzose taura neboka rako rekutarisira utano kana iwe uine mibvunzo pamusoro pekuwana zvakadai sekuwedzerwa retroperitoneal lymph nodes kana mibvunzo pamusoro pekukosha kwezviwanikwa izvi.
