Abstract: The fundamental idea of transumbilical endoscopic surgery (TUES) or laparo-endoscopic single site (LESS) surgery is to have all of the working ports entering the abdomen through a single incision, which could have better cosmetic results or less trauma. The history, current status and controversies of TUES are introduced in this article. The hotspot in TUES is to overcome difficulty in manipulation caused by external and internal conflict, and lack of triangulation. The range of TUES procedures is expanding rapidly. However, we should not overlook the safety for slightly improved cosmetic value. The multicenter, randomized and clinical trials are necessary to further elucidate the safety and efficiency of this new technique

Key words: Transumbilical, Laparoscopy, TUES, Single site surgery
