INDEPENDENT FACTORS FOR SMALL BOWEL OBSTRUCTION IN JORDANIAN PATIENTS POST EXPLORATORY LAPAROTOMY FOR TRAUMA

Objective: To assess the frequency and factors for small bowel obstruction after surgery in patients post exploratory laparotomy for trauma. Methods: This prospective and double blind investigation had 145 participants, males and females, 41.3-64.5 years and who were exposed to exploratory laparotomy for trauma at Prince Rashed military hospital, Irbid, Jordan and King Talal military hospital, Al Mafraq, Jordan during the period Nov 2015-Mar 2018. Small bowel obstruction after surgery is the existence of clinical features of obstruction between 7 days and 30 days after surgery or an obstruction presenting during postoperative 4 weeks and persisting over one week. Univariate analysis was achieved to assess patients having (Group I, n=32 patients) or not (Group II, n=113 patients) early postoperative small bowel obstruction, Continuous parameters and categorical parameters were assessed. Logistic regression was evaluated to recognize remarkable factors of small bowel obstruction after surgery. A P-value of less than 0.05 was remarkable. Results: 32 patients (22.1%) experienced early postoperative small bowel obstruction. Multivariate logistic analysis found male gender (P < 0.05) and Abbreviated Insult Scale for mesenteric insult (P < 0.05) as remarkable factors for postoperative small bowel obstruction. Conclusion: The frequency of early postoperative small bowel obstruction was 22.1%. Male gender and Abbreviated Insult Scale score for mesenteric insult were remarkable independent risk factors for early postoperative small bowel obstruction post exploratory laparotomy for trauma.
