<br><b>Introduction:</b> Postoperative intra-abdominal adhesions are a clinical condition that may develop after any abdominal surgery and constitute the leading cause of mechanical small bowel obstructions.</br> <br><b>Aim:</b> This study investigates factors which influence the formation of postoperative adhesion and evaluates the efficiency of applying minimally invasive surgical techniques in reducing adhesion.</br> <br><b>Material and methods:</b> Patients who underwent surgery to diagnose obstructive ileus in our clinic between January 2015 and January 2020 were analyzed retrospectively. Demographic data of the patients, operation details time between the operations and history of hospitalizations, postoperative mortality and morbidity, as well as the severity of complications were recorded. The patients included in the study were divided into groups according to the surgical technique applied in the first operation (laparoscopy/ laparotomy), the abdominal incision line (upper/lower/total), and the etiology of the primarily operated lesion (benign/malignant).</br> <br><b>Results:</b> One hundred eighteen (118) patients were included in the study. The mean age of patients was 61.2 ± 10.8 (39-82) years. Age, ileus history, time to the onset of ileus, length of hospital stay and the number of complications were shorter in the laparoscopy group as compared to the laparotomy group and the difference was found to be statistically significant. In addition, when patients were categorized according to the abdominal incision line, fewer hospitalizations and more frequent postoperative complications due to ileus were observed in the sub-umbilical incision group (p < 0.05).</br> <br><b>Conclusions:</b> Postoperative adhesion formation is currently one of the clinical conditions which pose a challenge to both the patient and the clinician due to its incidence and recurrence. However, adhesion formation can be reduced by applying minimally invasive surgical methods, especially laparoscopic surgery and precise maneuvers during surgery.</br>.
