Official title
A Randomized, Controlled Trial of Single-incision Laparoscopic (SILS) Versus Conventional Laparoscopic Appendectomy for the Treatment of Acute Appendicitis
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Recent advances in laparoscopic instrumentation have made it possible to perform intra-abdominal operations entirely through a small incision that can be hidden within the umbilicus. The goal is to perform surgery with fewer incisions and no visible scars. Other potential benefits are faster recovery, less pain, and fewer wound complications. The term SILS (Single Incision Laparoscopic Surgery) is being used to describe such techniques, and many have touted SILS as a major breakthrough in minimally-invasive surgery, moving the field closer to surgery that is bloodless, incisionless, and painless. Despite the hype, prospective comparisons of SILS versus conventional laparoscopy are lacking. Results of SILS procedures have generally been limited to case reports and small case series that lack controls. The investigators propose to conduct a prospective, randomized, single-center trial of SILS appendectomy versus conventional laparoscopic appendectomy to treat acute appendicitis. Primary end-points are operative time, complication rate, postoperative pain, recovery time, and long-term cosmetic outcome. The investigators hypothesize SILS appendectomy is equivalent to laparoscopic appendectomy with respect to operative time, complication rate, postoperative pain, and recovery time while providing a better cosmetic outcome.
