Laparoscopic appendicectomy (LA) and open appendicectomy (OA) showed similar postoperative outcomes in patients with acute appendicitis. While LA had a longer operating time, both surgical methods resulted in comparable recovery and return to work.

Area of Science:

  • Surgical innovation
  • Minimally invasive surgery
  • Gastrointestinal surgery

Background:

  • Assessing new laparoscopic surgical techniques is challenging due to surgeon learning curves and preference.
  • Standardized comparisons are needed to evaluate the efficacy of emerging surgical methods.

Purpose of the Study:

  • To prospectively compare laparoscopic appendicectomy (LA) with conventional open appendicectomy (OA) in patients with suspected acute appendicitis.
  • To evaluate postoperative outcomes and recovery between the two surgical approaches.

Main Methods:

  • A prospective randomized trial comparing LA and OA in 140 patients with suspected acute appendicitis.
  • Surgeons with comparable experience performed operations; postoperative management was independent.
  • Data collected included operating time, intraoperative complications, conversion rates, and postoperative recovery metrics.

Main Results:

  • Laparoscopic appendicectomy (LA) had a significantly longer operating time (mean 70.3 min) compared to open appendicectomy (OA) (mean 46.5 min).
  • 20% of LA cases required conversion to open surgery; no major intraoperative complications occurred in either group.
  • No significant differences were observed in postoperative pain, analgesic needs, diet reintroduction, hospital stay, or return to work between LA and OA.

Conclusions:

  • The postoperative course for patients undergoing laparoscopic appendicectomy (LA) does not significantly differ from conventional open appendicectomy (OA).
  • While LA may offer a trend towards fewer wound complications, overall recovery and patient outcomes are comparable.
  • This study supports the use of both techniques, highlighting the importance of surgeon experience in laparoscopic procedures.
