Introduction: Postoperative gastrointestinal motility dysfunction is one of the most common complications experienced by patients following surgery, particularly abdominal procedures. The duration of surgery contributes to the development of postoperative gastrointestinal motility dysfunction through a series of biological and physiological mechanisms. Objective: This study aimed to identify the duration of surgery among patients undergoing abdominal surgery, assess postoperative gastrointestinal motility dysfunction, and analyze the relationship between surgical duration and postoperative gastrointestinal motility dysfunction. Methods: This study employed a quantitative analytical design with a cross-sectional approach. The study population consisted of 52 patients who underwent abdominal surgery. A total of 45 respondents were selected using a stratified random sampling technique. Data were analyzed using the Spearman's rank correlation (Spearman's Rho) test with a significance level of α = 0.05. Results: The findings demonstrated a statistically significant relationship between surgical duration and postoperative gastrointestinal motility dysfunction, with a p-value of 0.001 (p < 0.05) and a correlation coefficient of 0.944. This result indicates a very strong positive correlation, suggesting that longer surgical duration is associated with a higher degree of postoperative gastrointestinal motility dysfunction
