Is acute appendicitis a surgical emergency?

Abstract

Urgent appendectomy has become the basis of management for acute appendicitis because of the disparity in morbidity and mortality rates between perforated and nonperforated appendicitis. Immediate surgery results in the confirmation of diagnosis and the control of sepsis without the risk of recurrent appendicitis. However, when notified by the emergency room of the diagnosis, many surgeons are opting to begin antibiotics and intravenous fluids and to schedule the appendectomy at their convenience. We hypothesize that using intravenous antibiotics and hydration to delay appendectomy until "normal business hours" has a negative impact on patient morbidity and mortality. During a 23-month period, the medical records of 81 patients at a single institution who underwent appendectomy were reviewed. All patients had preoperative CT scans and all operations were performed by one of two surgeons. Group A included those patients who underwent appendectomy within 10 hours of CT diagnosis and group B included those appendectomies performed greater than 10 hours after diagnosis. Wound complications, antibiotic use, total analgesic requirements, length of operation, and hospital length of stay were used for comparison. The average time to operation (3.18 vs 15.85 hours), operative time (54.1 vs 55.7 minutes), length of stay (2.65 vs 2.09 days), wound infections (4 vs 0), and antibiotic use at discharge (19 vs 3) for group A and B were not statistically different. This data suggests that delaying operative intervention for acute appendicitis to accommodate a surgeon's preference or to maximize a hospital's efficiency does not pose a significant risk to the patient.
