Purpose: This study aimed to investigate the incidence and risk factors of early postoperative small bowel obstruction (EPSBO) after laparotomy for trauma patients.
Methods: From 2009 to 2016, consecutive patients who had undergone laparotomy for trauma were retrospectively evaluated. EPSBO was defined as the presence of signs and symptoms of obstruction between postoperative days 7 and 30, or obstruction occurring anytime within 30 days and lasting more 7 days.
Results: Among 297 patients who met the inclusion criteria, 72 (24.2%) developed EPSBO. The length of hospital stay was significantly longer in patients with EPSBO than in those without EPSBO (median [interquartile range], 34 [21?48] days 24 [14?38] days, P < 0.001). Multivariate logistic analysis identified male sex (adjusted odds ratio [AOR], 3.026; P = 0.008), intraoperative crystalloid (AOR, 1.130; P = 0.031), and Abbreviated Injury Scale (AIS) score for mesenteric injury (AOR, 1.397; P < 0.001) as independent risk factors for EPSBO. The incidence of adhesive small bowel adhesion after 30 days postoperatively did not significantly differ between the 2 groups (with EPSBO, 5.6% without EPSBO, 5.3%; P = 0.571). Most of the patients with EPSBO were recovered by conservative treatment (95.8%).
Conclusion: After laparotomy for trauma patients, the incidence of EPSBO was 24.2% in our study. EPSBO was associated with a longer hospital stay. Male sex, use of intraoperative crystalloid, and AIS score for mesenteric injury were significant independent risk factors for EPSBO. Patients with these risk factors should be followed-up more carefully.
