Individualization of the best approach for adhesive small bowel obstruction

Abstract

AbstractBackgroundLaparoscopic postoperatives outcomes in adhesiolysis are promising but conversion and morbidity remains high. The objective of our study was to determine preoperative factors to individualize and select the most appropriate approach for each patient.MethodsPatients ≥18 years old undergoing emergent surgery for adhesive small bowel obstruction and internal hernias were evaluated. Bivariate and multivariate analysis were performed to investigate factors related to conversion to open surgery and to the type of adhesions.ResultsOf 333 patients, 224 were operated by laparotomy and 109 by laparoscopy (conversion rate: 40%). Previous abdominal wall mesh, type of adhesions, bowel lesion, need for intestinal resection and laparoscopic skills were statistically related to conversion. In the multivariate analysis, complex adhesions (OR 4.3, 95% CI 1.5–12.2; P = 0.006), the need for intestinal resection (OR 14.16, 95% CI 2.55–78.68; P = 0.002), and non‐advanced laparoscopy surgeons (OR 4.31, 95% CI 1.56–11.94; P = 0.005) were independent factors for conversion to open surgery. ASA III–IV, previous surgeries, previous abdominal mesh and previous adhesiolysis were related to complex adhesions. Previous laparoscopic surgery and internal hernia or closed loop in computed tomography were associated with simple adhesions as a cause of the obstruction. In the multivariate, previous adhesiolysis (OR 4.76, 95% CI 1.23–18.3; P = 0.023) and the findings on computed tomography were significantly related with the type of adhesion.ConclusionSome preoperative factors allow to individualize the surgical approach in the adhesive small bowel obstruction improving surgical outcomes.
