The patient was diagnosed and successfully treated using laparoscopy. We propose that laparoscopy is a viable option for diagnosis and treatment of patients with SBO and no history of abdominal surgery. CASE REPORT A 64-year-old female presented with 24 hours of nausea, abdominal pain, and vomiting. She denied any prior ab- dominal surgery or trauma. Her past medical history was significant only for hypertension, gastroesophageal reflux disease, and high cholesterol. An abdominal x-ray re- vealed multiple loops of dilated small bowel with air fluid levels consistent with a small bowel obstruction. Subse- quent computed tomography of the abdomen and pelvis showed multiple dilated loops of small bowel consistent with SBO, but no obvious underlying cause (Figure 1). The differential diagnosis included internal hernia, neo- plasm, spontaneous adhesion, stricture, or congenital ab- normality. The patient was treated conservatively overnight with Mercy Hospital of Pittsburgh, Pittsburgh, Pennsylvania, USA (all authors). bowel rest and nasogastric tube decompression.

Computed tomography has become the definitive radiographic study, as the scan will demonstrate the point of obstruction in addition to any other underlying pathology. Enteroclysis or a small bowel follow through is occasionally used to evaluate the small bowel mucosa or, less frequently, for therapeutic value. Initial treatment of SBO without associated fever, elevated white blood cell count, or abdominal pain is conservative. Definitive treatment of a small bowel ob- struction is directed towards the cause. Surgical interven- tion traditionally consisted of a laparotomy, although more surgeons are opting for a minimally invasive ap- proach.1 Few surgeons eagerly anticipate the fourth “lap and lysis” for recurrent SBO. Entry into the peritoneal cavity, small bowel enterotomy, ventral hernia, and enterocutaneous fistulae are all very real issues, and the postoperative Figure 2.
