| pubmed-article:11528606 | pubmed:abstractText | Preoperative histochemistry on rectal mucosal-submucosal specimens is the most important step in the diagnosis of Hirschsprung's disease and other dysganglionoses. Today, rectal mucosal-submucosal biopsy specimens are obtained by suction with the widely used tool first designed by Noblett in the late 1960s. The authors developed a new instrument, for which a patent has already been filed, for one-hand execution of rectal suction biopsies, which will make this operation easier and faster. | lld:pubmed |
