Summary

Minilaparoscopic appendectomy using 2-mm instruments shows comparable outcomes to conventional laparoscopic appendectomy. However, retrocecal appendix and older patient age are risk factors for conversion in this minimally invasive approach.

Area of Science:

  • Minimally Invasive Surgery
  • Gastrointestinal Surgery
  • Surgical Technology

Background:

  • Conventional laparoscopic appendectomy utilizes larger instruments (5- and 10-mm).
  • The feasibility of using smaller 2-mm instruments for appendicitis treatment is under investigation.
  • Identifying limitations for smaller instrument use is crucial for surgical advancement.

Purpose of the Study:

  • To assess the feasibility of 2-mm laparoscopic instruments in appendicitis treatment.
  • To identify risk factors associated with the limited use of 2-mm instruments.
  • To compare perioperative outcomes of minilaparoscopic versus conventional laparoscopic appendectomy.

Main Methods:

  • Minilaparoscopic appendectomy (2-mm instruments) was performed on 26 patients.

  • A control group of 32 patients underwent conventional laparoscopic appendectomy (5- and 10-mm instruments).
  • Statistical analysis included Student t test and Fisher exact test (P < 0.05).

    • Main Results:

    • Mean operative time was shorter for minilaparoscopic appendectomy (69.5 min) compared to conventional (85.5 min) (P = 0.02).
    • Minilaparoscopic appendectomy was completed in 50% of patients; conversions were associated with retrocecal appendix and older age (P = 0.05).
    • No significant differences in postoperative length of stay or complication rates were observed between groups.

    Conclusions:

    • Minilaparoscopic appendectomy with 2-mm instruments offers comparable perioperative outcomes to conventional laparoscopic appendectomy.
    • Retrocecal appendicitis and increasing patient age are significant risk factors limiting the use of 2-mm instrumentation.
    • Further research may optimize the application of 2-mm instruments in specific appendicitis cases.
