Abstract
Background Early postoperative small bowel obstruction (EPSBO) is a distinct clinical entity that is often difficult to differentiate from postoperative ileus. Methods A literature search was performed for articles dealing with early postoperative small bowel obstruction using Medline and Google™. Results and conclusion When bowel function does not return within 5 days after surgery, causes of persistent ileus should be excluded and treated. Most instances of mechanical EPSBO can be treated expectantly for at least 10–14 days with almost no risk of bowel strangulation. Some causes of obstruction (for example herniation at a laparoscopic trocar site) require early reintervention, whereas in other cases (such as radiation enteritis, carcinomatosis) reintervention may be deferred indefinitely. Many episodes of EPSBO resolve without the cause being elucidated.
