Laparoscopic appendectomy offers significant benefits over open appendectomy, including shorter hospital stays and fewer complications. This surgical approach leads to better patient outcomes and a higher rate of routine discharge after appendicitis treatment.

Area of Science:

  • Surgical Procedures
  • Gastrointestinal Surgery
  • Public Health

Background:

  • Conflicting results from single-institutional trials necessitate further investigation into laparoscopic versus open appendectomy.
  • A definitive consensus on the advantages of each appendectomy technique remains elusive.
  • Nationwide data analysis is crucial for establishing evidence-based surgical practice guidelines.

Purpose of the Study:

  • To compare length of hospital stay, in-hospital complications, mortality, and routine discharge rates.
  • To evaluate laparoscopic versus open appendectomy outcomes.
  • To utilize a representative nationwide database for robust statistical analysis.

Main Methods:

  • Analysis of the 1997 Nationwide Inpatient Sample, representing approximately 20% of US hospital discharges.

  • Selection of patients based on ICD-9 procedure codes for laparoscopic and open appendectomy.
  • Application of multiple linear and logistic regression for risk-adjusted endpoint assessment.

    • Main Results:

    • Laparoscopic appendectomy was associated with a significantly shorter median hospital stay (2.06 vs. 2.88 days).
    • Lower rates of infections (OR=0.5), gastrointestinal complications (OR=0.8), and overall complications (OR=0.84) were observed with laparoscopic appendectomy.
    • A higher rate of routine discharge was found for laparoscopic appendectomy (OR=3.22).

    Conclusions:

    • Laparoscopic appendectomy demonstrates significant advantages over open appendectomy.
    • Key benefits include reduced hospital stay, improved routine discharge rates, and decreased postoperative morbidity.
    • These findings support the broader adoption of laparoscopic appendectomy.
