Materials and Methods: The study group comprised 121 patients who underwent laparoscopic surgery for small-bowel obstruction. Results: Previous operations were open surgery in 107 patients and laparoscopic surgery in 14. On univariate analysis, 4 risk factors were related to conversion to open surgery: radiotherapy (P=0.0002), previous episode of intestinal obstruction (P=0.0064), bleeding volume of ≥50 mL (P=0.0059), and the presence or absence of previous bowel resection (P=0.0269). On multivariate analysis, only radiotherapy was an independent risk factor for conversion to open surgery (odds ratio, 5.5141; P=0.0091). Conclusions: Laparoscopic surgery can be safely performed in patients with postoperative small-bowel obstruction and is considered an effective treatment with a low rate of recurrent bowel obstruction.
