Icharamba iripo kusvikira kupora kwechisikigo uye kugadzirisa matishu kwemuviri kwapera (anenge masvondo maviri), uye zvino ichabviswa kuburikidza nekuvhiya endoscopic pasina kudiwa kwekupindira kwechipiri kwekuvhiya. Izvi zvinobvisa kudiwa kwevarwere kutsungirira kurwadziwa kweartificial anus uye kupfeka mabhegi ekugadzira. Inogona kubviswa mumazuva gumi, uye murwere anogona kutangazve hupenyu hwakajairika
Chinangwa Kushandiswa
Chiitiko chekudonha kweanastomotic mushure mekuvhiyiwa kwegomarara remukati ndeye 5% kusvika 15%. Kamwe kudonha kweanastomotic kunoitika, hakungokanganisa kupora kwemurwere mushure mekuvhiyiwa uye kunowedzera kugara kwavo muchipatara, asi kunodawo kudzokororwa nguva nenguva kana zvichidikanwa, kuwedzera marwadzo omurwere uye mari yekurapa; Zviitiko zvakakomba zvinogona kutungamirira kune septic shock kana kunyange rufu; Panguva imwecheteyo, zvinogonawo kutungamirira kumatambudziko akareba senge postoperative anastomotic stenosis uye kusagadzikana kwekuita defecation, zvichikanganisa hupenyu hwehupenyu hurefu hwemurwere. Maitiro ekudzivirira anastomotic leakage ichiri kutarisisa uye kuoma mukutsvagisa kwekiriniki mukati memunyika nekunze, uye mhinduro dzinogutsa hadzisati dzawanikwa. Chidzidzo ichi chinotora nzira itsva yekudzivirira, inosanganisira kuisa intestinal stent inonzi "anastomotic leak proof protective stent" panzvimbo yeanastomotic panguva yekuvhiyiwa, zvichiwana mhedzisiro yakanaka.

Rusvingo rwemukati rwakafukidzwa nefirimu rinoonekera risina mvura, uye stent ine chitarisiko chedumbbell ine groove yakanaka zvishoma pakati. Ona Mufananidzo 1. Mugumo wepamusoro webhakiti wakareba 20mm uye une dhayamita yekunze ye 33mm, iyo inopindirana nehupamhi hwemukati we sigmoid colon; Mugumo wepazasi wakareba 20mm uye une dhayamita yekunze ye28mm, idiki zvishoma pane dhayamita yemukati yemucheto wezasi we rectum, kuitira kuti zviri mukati memukati zvakaunganidzwa mugororo zvigone kuburitswa nenguva. Iyo groove yakareba 10mm uye ine dhayamita yekunze ye20-25mm, iyo inoenderana nekucheka blade dhayamita yemhando dzakasiyana dzetubular staplers kuti ive nechokwadi chekuti radial tension yekuvhura anastomotic haina kuwedzera mushure mekunge bracket yaiswa. Nokudaro, kana uchiisa bhakiti, kusungirirwa kunofanira kuiswa mu groove. Iyo yekumberi bracket inomanikidzwa kuita kaviri-layer catheter ine dhayamita yekunze ye8mm, uye bracket iri pakati pemukati nekunze catheter.
