Introduction to Intestinal Stents

ʻO ka stent intestinal kahi lāʻau lapaʻau, maʻamau he ʻano tubular i hana ʻia me ka metala a i ʻole ka plastic, i hoʻohana ʻia e hoʻoponopono i ka ʻōpū o ka ʻōpū i hoʻokumu ʻia e ka stenosis intestinal a i ʻole occlusion. Hiki ke hoʻokomo ʻia nā ʻōpū o ka ʻōpū ma lalo o ka endoscopy a i ʻole ma nā puka liʻiliʻi o ka ʻili, a hiki i ka hoʻokomo ʻana i nā stents ke hoʻonui i ka wahi haiki o ka ʻōpū e hoʻihoʻi i ka paʻa a me ka hana. Hiki ke hoʻohana ʻia ka hoʻokomo ʻana o ka stent intestinal no ka mālama ʻana i nā maʻi ʻōpū he nui, e like me ka ʻōpū o ka ʻōpū, ka maʻi ʻeha o ka ʻōpū, ka maʻi maʻi pancreatic, a me nā mea ʻē aʻe. ke ola o nā maʻi a hoʻohaʻahaʻa i ko lākou ʻeha a me nā hōʻailona hōʻoluʻolu.

He ʻano lāʻau lapaʻau hou ʻo Intestinal stent, a hiki ke ʻike ʻia kona hoʻomohala ʻana i ka hopena o nā makahiki 1970 a me nā makahiki 1980. ʻO ka stent mua o ka ʻōpū i hana ʻia me ka plastic a ua hoʻohana nui ʻia e mālama i ka ʻāʻī o ka ʻōpū o luna i hana ʻia e nā maʻi ʻino e like me ka maʻi maʻi esophageal a me ka maʻi kanesa. Me ka hoʻomohala ʻana o ka ʻenehana lapaʻau, ua hoʻohana nui ʻia nā stents metala i ka mālama ʻana i ka ʻāʻī o ka ʻōpū.

I ka makahiki 1991, ua ʻae ka Food and Drug Administration (FDA) o ʻAmelika i ka stent metala mua no ka mālama ʻana i ka biliary stricture a me ka occlusion. Mai ia manawa, ua hoʻonui nui ʻia ka hoʻohana ʻana i nā stents metala e mālama i nā ʻano stricture gastrointestinal a me ka occlusion, e like me ka esophageal cancer, gastric cancer, duodenal cancer, biliary cancer, pancreatic cancer cancer a me colorectal cancer.

I nā makahiki i hala iho nei, me ka holomua o ka ʻenehana lapaʻau, ua hoʻomaikaʻi hou ʻia ka hoʻolālā a me nā mea hana o nā stents intestinal. ʻOi aku ka maikaʻi o ka hoʻolālā ʻana o nā stents intestinal hou me nā kumu biomechanical, hiki ke hoʻololi maikaʻi i nā ʻano physiological o ka ʻōpū a hoʻoponopono i nā kūlana pathological paʻakikī. I ka manawa like, ʻoi aku ka ʻokoʻa o ke koho ʻana o nā mea, me ke kila kila, ka cobalt chromium alloy, ka titanium maʻemaʻe, a me ka nickel titanium alloy. ʻAʻole i loaʻa i kēia mau mea hou nā waiwai mechanical ʻoi aku ka maikaʻi, akā ʻoi aku ka maikaʻi o ka corrosion-resistant a me ka biocompatible, hiki ke hōʻemi i ka hopena o nā hopena ʻino a me nā hoʻopiʻi ma hope o ka stent implantation.

Ma ke ʻano he ala lapaʻau wikiwiki a maikaʻi hoʻi, ua hoʻohana nui ʻia ka stent a he hana koʻikoʻi i ka mālama ʻana i ka stenosis intestinal a me ka occlusion. Me ka hoʻomau ʻana o ka hoʻomohala ʻana a me ka hoʻomaikaʻi ʻana i ka ʻenehana, ua manaʻo ʻia e loaʻa i nā stents intestinal kahi ākea ākea o nā manaʻo noi i ka wā e hiki mai ana.
