Postoperative Complications and Recovery after Surgical Procedures: A 10 Year PRISMA Based Systematic Review
Keywords:
postoperative complications, surgical site infection, hemorrhage, pulmonary complications, delirium, recovery, PRISMAAbstract
This systematic review synthesizes evidence from the past decade on the most common postoperative complications across surgical specialties and their impact on recovery, following PRISMA methodology. Across 2016–2025, general postoperative complication rates in large cohorts ranged around 20%, with bleeding, surgical site infection (SSI), pulmonary and cardiac events, and postoperative delirium emerging as dominant entities affecting early outcomes. SSIs occurred in roughly 10–25% of patients in high‑risk settings and were frequently driven by multidrug‑resistant Gram‑negative organisms, substantially prolonging length of stay and impairing wound recovery. Multiple studies highlighted that cascades of complications significantly increase mortality, with mortality after any complication reaching almost sixfold that of uncomplicated cases. Recovery trajectories were strongly influenced by preoperative risk profile, procedure complexity, perioperative care, and follow‑up intensity, with structured infection prevention and early mobilization associated with improved functional recovery. Future work should standardize complication reporting and recovery metrics to enable high‑quality meta‑analysis, particularly in low‑ and middle‑income countries where data remain scarce.
