Abstract
INTRODUCTION: To our knowledge, this study is the first to identify the predictive factors and outcomes of prolonged operative time associated with laparoscopic appendectomy. We aimed to identify preoperative factors that influence operation time and to determine how operative time affects laparoscopic appendectomy outcomes.
METHODS: The medical records of 3,049 patients who had undergone laparoscopic appendectomy between January 2008 and December 2014 were retrospectively reviewed. Prolonged operative time was defined in the top 10% according to distribution (>90 min). A multivariate regression model was generated to assess potential predictive factors and outcomes of prolonged operative time.
RESULTS: In laparoscopic appendectomy for non-perforated appendicitis, independent factors that predict a prolonged operative time as identified through multivariate analysis were elevated C-reactive protein levels, symptom duration of more than 3 days, and computed tomography findings indicating an appendiceal diameter of more than 10 mm. In laparoscopic appendectomy for perforated appendicitis, overweight, elevated C-reactive protein, symptom duration of more than 3 days, and computed tomography findings of abscess were independent predictive factors for prolonged operative time. Prolonged surgery increases the risk of complications, prolonged hospital stay, and readmission.
CONCLUSIONS: Overweight, elevated C-reactive protein, symptom duration of more than 3 days, appendiceal diameter of more than 10 mm, and abscess were independent predictive factors of prolonged operative time. Furthermore, prolonged operative time was associated with adverse postoperative outcomes after laparoscopic appendectomy.
