Laparoscopic Approach to Appendectomy Reduces the Incidence of Short- and Long-Term Post-operative Bowel Obstruction: Systematic Review and Pooled Analysis

The aim of this meta-analysis was to determine the effect of laparoscopic appendectomy (LA) compared to open appendectomy (OA) on short-term and long-term post-operative bowel obstruction.
Medline, Embase, trial registries, conference proceedings and reference lists were searched. Subset analysis was performed for paediatric patients, patients who presented with perforated appendicitis and studies with long-term follow-up and surveillance for bowel obstruction and with surgery for bowel obstruction.
Overall, 29 studies comprising 159,729 patients (60,875 LA versus 98,854 OA) were included. LA was associated with a significant reduction in the incidence of post-operative bowel obstruction in the general population (pooled odds ratio (POR) = 0.43 [95 %C.I. 0.3–0.63]). Subset analysis demonstrated that LA significantly reduced the incidence of post-operative bowel obstruction in paediatric patients (POR = 0.48 [95 %C.I. 0.3–0.78]) and patients with perforated appendicitis (POR = 0.44 [95 %C.I. 0.26–0.74]). Furthermore, LA was associated with a significantly reduced incidence of long-term bowel obstruction (POR = 0.33 [95 %C.I. 0.19–0.56]) and bowel obstruction requiring surgery (POR = 0.31 [95 %C.I. 0.2–0.48]).
This present meta-analysis provides evidence to clearly demonstrate the benefits of a laparoscopic approach to appendectomy as reflected by a reduction in short- and long-term adhesive bowel obstruction. Important future areas for assessment include the influence of surgical approach on long-term quality of life following appendectomy.
