Laparoscopic Appendectomy: A Prospective Randomized Trial."
Annals of Surgery. 254, (2011): 586-590.
This is a definitive study in 360 patients with a 90% power. The
primary outcome variable is post-operative infection.
Likely there are several secondary variables that will show
small differences between groups. This study will precisely
quantify these variables to allow for adequate consultation from
surgeons to families with children with acute appendicitis. The
single-incision approach is not controlled for and surgeons may
vary in the technique and equipment they choose to employ.
Because the differences between the two groups are likely to be
small and cosmesis is a proposed advantage of single-incision
surgery, we are also using a validated tool to measure scar
satisfaction at six weeks and six months after the
