Abstract

PURPOSE
Conventional laparoscopic appendectomy (LA) is a widely used treatment for appendicitis. Nowadays, single incision laparoscopic appendectomy (SILA) is increasingly used as an alternative treatment for appendicitis. The purpose of this study is to evaluate the clinical significance and differences between LA and SILA.
METHODS
A total of 519 patients undergoing LA or SILA between January 2011 and December 2012 were identified in a retrospectively collected database. Patients' characteristics and peri-operative variables were analyzed.
RESULTS
LA was performed in 485 patients and SILA was performed in 34 patients. Mean operation time for the LA group was 62.7 minutes (range 23.3~68.1) and that for the SILA group was 62.7 minutes (range 50.9~74.5). This difference of operation time was statistically significant. In the learning curve of SILA, operation time was gradually decreased. No significant differences in hospital stay and peri-operative complications were observed between groups.
CONCLUSION
Although operation time for SILA was longer than that for LA, SILA was safe. Therefore, a prospective study should be conducted in order to confirm the possibility of application to most appendicitis patients.
