Transumbilical Laparoscopy-assisted Appendectomy
Transumbilical Laparoscopy-assisted Appendectomy
transumbilical laparoscopic-assisted appendectomy (TULAA) was reported that the operation
 time was shorter and the postoperative frequency of complications was not high compared to
 conventional laparoscopic appendectomy (CLA) with three conventional ports in retrospective
 studies. The purpose of this study is to evaluate the outcomes of transumbilical
 laparoscopic-assisted appendectomy (TULAA) and to compare them to the outcomes of CLA.
Single port appendectomy can be considered as the better option than conventional
 laparoscopic appendectomy (CLA) for pediatric patients with uncomplicated acute appendicitis
 in cosmetic aspect. However, this technique has not gained popularity because it has been
 regarded as a tricky and time-consuming procedure. Recently, the frequency of implementation
 of transumbilical laparoscopy-assisted appendectomy (TULAA) is increasing in pediatric
 patients with uncomplicated appendicitis. The reason that this operation is possible in
 children, is that the length between umbilicus and appendix is shorter than that of an adult,
 and the abdominal wall is flexible, so that the appendix can be extracted through umbilical
 incision. It was reported that the operation time was shorter and the postoperative frequency
 of complications was not high compared to the laparoscopic appendectomy with three
 conventional ports. The purpose of this study is to evaluate the outcomes of transumbilical
 laparoscopic-assisted appendectomy (TULAA) and to compare them to the outcomes of CLA.
