Is postponed laparoscopic appendectomy justified for patients with acute appendicitis?

Abstract

Introduction

Recent meta‐analyses revealed that laparoscopic appendectomy (LA) is a feasible procedure even for patients with complicated appendicitis. More than a few patients with acute appendicitis arrive at the hospital during night shifts and have their operation postponed for various reasons. However, the feasibility and disadvantages of this so‐called "postponed laparoscopic appendectomy" (PLA) remain controversial.

Methods

We included 149 patients who underwent LA for acute appendicitis within 48 h of diagnosis between January 2013 and May 2018. Patients were divided into an immediate LA group (patients who underwent LA within 4 h of diagnosis, n = 84) and a PLA group (patients who underwent LA 4–48 h after diagnosis, n = 65). Comparisons were made between these groups.

Results

The preoperative characteristics of the patients in the immediate LA and PLA groups were not significantly different. Operative time was significantly longer in the PLA group than in the LA group (92.5 ± 40.8 vs 78.1 ± 29.7 min, P = 0.012). The incidence of postoperative complications (grade II or higher) was significantly greater in the PLA group than in the LA group (32.3% vs 17.8%, P = 0.041). Multivariate analysis revealed that a preoperative CT finding of periappendiceal fluid (P = 0.005, odds ratio = 4.71) and surgery 4–48 h after diagnosis (P = 0.005, odds ratio = 4.425) were independent risk factors of postoperative complications (grade II or higher).

Conclusions

For patients with acute appendicitis, surgeons should perform immediate LA, if that is the patient's preferred surgical treatment, as long as there is no special reason to postpone surgery.
