Chithandizo cha endoscopic cha zotupa zam'mimba zam'mimba: mfundo zazikulu 3 zomwe zafotokozedwa mwachidule m'nkhani imodzi.

Submucosal tumors (SMT) ya m'mimba ndi zotupa zokwezeka zochokera ku muscularis mucosa, submucosa, kapena muscularis propria, komanso zitha kukhala zotupa za extraluminal.Ndi chitukuko chaukadaulo wazachipatala, njira zopangira opaleshoni zachikhalidwe zalowa pang'onopang'ono m'nthawi ya chithandizo chochepa kwambiri, monga l.opaleshoni ya laparoscopic ndi opaleshoni ya robotic.Komabe, muzochita zachipatala, zikhoza kupezeka kuti "opaleshoni" si yoyenera kwa odwala onse.M'zaka zaposachedwa, mtengo wa chithandizo endoscopic walandira chidwi pang'onopang'ono.Mtundu waposachedwa wa mgwirizano wa akatswiri aku China pa matenda a endoscopic ndi chithandizo cha SMT watulutsidwa.Nkhaniyi iphunzira mwachidule chidziwitso choyenera.

1.SMT mliri wa khalidweotsutsa

(1) Zochitika za SMT ndi yosiyana m'madera osiyanasiyana a m'mimba, ndipo m'mimba ndi malo omwe amapezeka kwambiri a SMT.

Zochitika zosiyanasiyanas mbali za m`mimba thirakiti ndi wosagwirizana, ndi chapamwamba m`mimba thirakiti kukhala ambiri.Mwa izi, 2/3 imapezeka m'mimba, ndikutsatiridwa ndi esophagus, duodenum, ndi colon.

(2) The histopathologicall mitundu ya SMT ndi yovuta, koma ma SMT ambiri ndi zilonda zowopsa, ndipo ochepa okha ndi owopsa.

A.SMT imaphatikizapo ayiN-neoplastic zotupa monga ectopic pancreatic minofu ndi zotupa za neoplastic.

B. Pakati pa zotupa za neoplastics, ma leiomyomas a m'mimba, lipomas, Brucella adenomas, zotupa zama cell a granulosa, schwannomas, ndi zotupa za glomus nthawi zambiri zimakhala zowopsa, ndipo zosakwana 15% zimatha kuwoneka ngati minofu Phunzirani zoyipa.

C. M'mimba stromal zotupa (GIST) ndi zotupa za neuroendocrine (NET) mu SMT ndi zotupa zomwe zili ndi mphamvu zina zowopsa, koma izi zimadalira kukula kwake, malo ndi mtundu wake.

D. Malo a SMT ndi okhudzanaku gulu la pathological: a.Leiomyomas ndi mtundu wamba wamtundu wa SMT mum'mero, womwe umawerengera 60% mpaka 80% ya SMTs zam'mimero, ndipo nthawi zambiri zimachitika pakati ndi m'munsi zigawo za mmero;b. Mitundu ya matenda a m'mimba ya SMT ndi yovuta kwambiri, yokhala ndi GIST, leiomyoMa ndi ectopic kapamba omwe amapezeka kwambiri.Pakati pa chapamimba SMT, GIST imapezeka kwambiri mu fundus ndi thupi la m'mimba, leiomyoma nthawi zambiri imapezeka kumtima ndi kumtunda kwa thupi, ndipo ectopic pancreas ndi ectopic pancreas ndizofala kwambiri.Lipomas amapezeka kwambiri m'mimba;c.Lipomas ndi cysts ndizofala kwambiri m'madera otsika ndi a bulbous a duodenum;d.Mu SMT ya m'munsi m'mimba thirakiti, ma lipomas ndi omwe amapezeka kwambiri m'matumbo, pomwe ma NET ndi omwe amapezeka kwambiri mu rectum.

(3) Gwiritsani ntchito CT ndi MRI kuti muwerenge, kuchiza, ndikuwunika zotupa.Kwa ma SMT omwe akuganiziridwa kuti ndi owopsa kapena ali ndi zotupa zazikulu (zautalim'mimba mwake> 2 cm), CT ndi MRI akulimbikitsidwa.

Njira zina zojambulira, kuphatikizapo CT ndi MRI, ndizofunikanso kwambiri pozindikira matenda a SMT.Amatha kuwonetsa mwachindunji malo a chotupa, mawonekedwe a kukula, kukula kwa chotupa, mawonekedwe, kukhalapo kapena kusapezeka kwa lobulation, kachulukidwe, homogeneity, kuchuluka kwa kukulitsa, ndi mizere yamalire, ndi zina zambiri, ndipo amatha kupeza ngati ndi kuchuluka kwaKuchuluka kwa khoma la m'mimba. Chofunika kwambiri, kufufuza kojambula kumeneku kungathe kudziwa ngati pali kuukira kwa ziwalo zoyandikana ndi zilondazo komanso ngati pali metastasis mu peritoneum yozungulira, ma lymph nodes ndi ziwalo zina.Ndiwo njira yayikulu yopangira matenda, chithandizo ndi kuwunika kwa zotupa.

(4) Kuyesa kwa minofu sikubwereransozopangira ma SMTs abwino omwe amatha kuzindikirika ndi endoscopy wamba kuphatikiza ndi EUS, monga lipomas, cysts, ndi kapamba ectopic.

Pa zotupa zomwe zikuganiziridwa kuti ndizowopsa kapena ngati endoscopy yodziwika bwino yophatikizidwa ndi EUS siyingawunikire zotupa zowopsa kapena zowopsa, kuwongolera singano motsogozedwa ndi EUS kungagwiritsidwe ntchito (endoscopic ultrasonography guided fine n.eedle aspiration/biopsy, EUS-FNA/FNB), mucosal incision biopsy(mucosalincision-assisted biopsy, MIAB), ndi zina zotero.Poona zofooka za EUS-FNA ndi zotsatira zotsatila za endoscopic resection, kwa iwo omwe ali oyenerera opaleshoni ya endoscopic, poyang'ana kuti chotupacho chikhoza kuchotsedwa kwathunthu, mayunitsi omwe ali ndi luso lachipatala la endoscopic akhoza kuthandizidwa ndi odziwa zambiri. The endoscopist amachita endoscopic resection mwachindunji popanda kupeza preoperative pathological matenda.

Njira iliyonse yopezera zitsanzo za pathological musanachite opaleshoni imakhala yovuta ndipo idzawononga mucosa kapena kuchititsa kumamatira ku minofu ya submucosal, potero kumawonjezera vuto la opaleshoni ndipo mwinamwake kuonjezera kuopsa kwa magazi, perfo.kudya, ndi kufalitsa chotupa.Choncho, preoperative biopsy sikofunikira.Zofunikira, makamaka kwa ma SMT omwe amatha kuzindikiridwa ndi endoscopy wamba kuphatikiza ndi EUS, monga lipomas, cysts, ndi kapamba ectopic, palibe zitsanzo za minofu zomwe zimafunikira.
