Patterns and impact of early surgical complications after gastrointestinal surgery: a narrative review
Keywords:
gastrointestinal surgery, postoperative complications, anastomotic leakage, surgical site infection, postoperative ileus, mortality, risk stratification, perioperative careAbstract
Early postoperative complications remain a major determinant of outcomes after gastrointestinal (GI) surgery, despite advsances in minimally invasive techniques and perioperative care. Surgical site infection (SSI), anastomotic leakage, postoperative ileus, and cardiopulmonary events account for most morbidity, re‑interventions, and deaths within 30 days. Patient‑related risk factors (age, comorbidities, malnutrition, poor performance status) and procedure‑related factors (emergency setting, prolonged operative time, blood loss, and anastomotic complexity) synergistically increase complication risk. This narrative review summarizes the epidemiology of common early complications after major GI procedures and highlights modifiable perioperative risk factors and outcome patterns, using a simplified comparative model of gastrectomy, colorectal resection, and small‑bowel resection. Hypothetical comparative data illustrate differences in SSI, anastomotic leakage, ileus, and 30‑day mortality as a framework for quality‑improvement and risk‑stratification strategies. Understanding complication profiles and their interaction with baseline risk is essential to optimize perioperative pathways, guide shared decision‑making, and prioritize preventive interventions in GI surgery.
