Their research was published online in the British Journal of Surgery on March 3 and will appear in the Journal\u2019s May issue. The produced nanosheets, made from polylactic acid, do not exacerbate infections, allowing them to be used even when a patient suffers from an infection. Many expect the nanosheets to help prevent intestinal adhesion during perforation peritonitis and in the future, intestinal adhesion in young children.<\/p>\n<h3>Research summary<\/h3>\n<p>Intestinal adhesion can occur after surgery and cause issues when consuming food. For these patients, even if their surgery is a success, their overall quality-of-life drops. During perforation peritonitis, it is especially easy for intestinal adhesion to occur and there are currently no effective treatments. Following surgery in a young child, intestinal adhesion can make it difficult to consume food, drastically hindering the child\u2019s development. By utilizing the polylactic acid nanosheets, we can effectively prevent this from happening.<\/p>\n<div id=\"attachment_38497\" class=\"wp-caption alignleft\"><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-38497   \" alt=\"\u30ca\u30ce\u7d46\u5275\u818f\u3092\u3057\u3087\u3046\u819c\u304c\u6b20\u640d\u3057\u305f\u5c0f\u8178\u306b\u8cbc\u308b\u3068\u3053\u308d\" src=\"https:\/\/www.waseda.jp\/top\/en\/assets\/uploads\/2016\/03\/20160307_fig2-360x270.png\" width=\"252\" height=\"189\" \/><p class=\"wp-caption-text\">The &#8220;nanosheet,&#8221; or adhesive plaster (the transparent square) attached to a mouse&#8217;s damaged small intestine<\/p><\/div>\n<p>The research group from the National Defense Medical College, in collaboration with Waseda University, produced nanosheets approximately 80 nm thick that are capable of sealing holes in a collapsed lung as well as tears in large veins that lead to heavy bleeding.
