However, the intraoperative evaluation of the appendix is difficult, as the negative appendectomy rate remains 12%\u201318%.

In 57% (841\/1,465), a laparoscopic appendectomy was performed, with 9% ( n = 75) negative appendectomies. In 51% of the negative appendectomies, the visual assessment of the appendix was decisive in performing the appendectomy. In 33%, the surgeon was in doubt whether the appendix was inflamed or normal. In 4%, the surgeon was aware he removed a healthy appendix, and in 9%, an appendectomy was performed for different reasons.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>In more than half of the microscopic healthy appendices, the surgeon was convinced of the diagnosis appendicitis during surgery.
