A proportion of these patients will require further surgery because of high risk features, which include mesoappendiceal involvement or an involved margin. While an open appendicectomy technique usually involves en bloc mesoappendiceal resection, the increasingly common laparoscopic method often skeletonizes the appendix, leaving the mesoappendix in situ. This retrospective observational study investigates whether routine resection of the mesoappendix rather than skeletonization would reduce the need for further surgery in patients with an incidental finding of appendiceal neuroendocrine neoplasm.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We included appendicectomies performed over an 11\u2010year period at <jats:styled-content style=\"fixed-case\">A<\/jats:styled-content>uckland <jats:styled-content style=\"fixed-case\">C<\/jats:styled-content>ity <jats:styled-content style=\"fixed-case\">H<\/jats:styled-content>ospital and identified all cases of incidental appendiceal neuroendocrine neoplasms.
