Questions
Laparoscopy vs open for acute appendicitis?

Laparoscopy vs Open Appendectomy
Acute Appendicitis
Less wound infx with laparoscopy
Stapler vs cautery/endo loop technique
-

4/24
Laparoscopy vs Open Appendectomy
Perforated Appendicitis
Far fewer (almost none)wound infx with
laparoscopic approach
Allows surgeon tosuction/irrigate underdirect visualization
Less small bowelobstruction (SBO)

Conclusions
There is no difference in infectiouscomplications, recovery or defervescenceafter perforated appendicitis between
Ceftriaxone/Metronidazole and AGC
Ceftriaxone/Metronidazole is more cost-
effective than AGC
