Numerous single-institutional randomized clinical trials have assessed the efficacy of laparoscopic and open appendectomy. However, the results are conflicting.
In this study, doctors from Durham, North Carolina, compared length of hospital stay, in-hospital complications and mortality, and rate of routine discharge between laparoscopic and open appendectomy.
The team selected patients with primary ICD-9 procedure codes for laparoscopic and open appendectomy from the 1997 Nationwide Inpatient Sample.
They used multiple linear and logistic regression analyses to assess the risk-adjusted endpoints.

The team analyzed the discharge abstracts of 43,757 patients.
Of these patients, 17% and 83% underwent laparoscopic and open appendectomy, respectively.
Patients were an average age of 30.7 years. They were mainly white (58%) and male (59%).
The doctors determined that laparoscopic appendectomy was associated with shorter median hospital stay, lower rate of infections, decreased GI complications, lower overall complications, and higher rate of routine discharge.
Dr Ulrich Guller's team concluded, "Laparoscopic appendectomy has significant advantages over open appendectomy with respect to length of hospital stay, rate of routine discharge, and postoperative in-hospital morbidity".
