Advantages of laparoscopic appendectomy in the elderly

Area of Science:

• Surgery
• Geriatric Medicine
• Minimally Invasive Procedures

Background:

• The number of elderly patients undergoing appendectomy is rising.
• The benefits of laparoscopic appendectomy (LA) in this demographic are not well-established.
• Open appendectomy (OA) is the traditional approach.

Purpose of the Study:

• To compare perioperative outcomes of LA versus OA in elderly patients.
• To determine if LA offers advantages in the elderly population.
• To analyze outcomes for perforated appendicitis in the elderly.

Main Methods:

• Retrospective review of the North Carolina Hospital Association Patient Data System (1997-2003).
• Inclusion of adult patients (>18 years) undergoing appendectomy, with a focus on those aged 65 and older.
• Comparison of length of stay, charges, complications, discharge location, and mortality between LA and OA groups.

Main Results:

• Elderly patients undergoing LA had shorter LOS (4.6 vs 7.3 days), higher discharge-to-home rates (91.4% vs 78.9%), fewer complications (13.0% vs 22.4%), and lower mortality (0.4% vs 2.1%) compared to OA.
• For perforated appendicitis in the elderly, LA showed shorter LOS (6.8 vs 9.0 days) and higher discharge-to-home rates (86.6% vs 70.9%) with similar charges and mortality.
• Elderly patients undergoing LA had higher total charges than younger adults (18-64 years) but equivalent mortality rates.

Conclusions:

• Laparoscopic appendectomy (LA) demonstrates significant advantages over open appendectomy (OA) in elderly patients, including reduced mortality, complications, and length of stay.
• The laparoscopic approach is particularly beneficial for elderly patients with perforated appendicitis, leading to shorter hospitalizations and more home discharges.
• While hospitalization charges are higher for elderly patients undergoing LA compared to younger adults, mortality rates are comparable, suggesting LA may be the preferred method for appendectomy in the elderly.
