The generalized abdominal pain started 3 days ago and is associated with several episodes of nonbloody and nonbilious emesis.

He was discharged with medication for constipation. However, he continues to have pain, emesis, and progressive abdominal distention. Radiographs at our ED today reveal unchanged stool burden as well as an incidental left-sided pleural effusion and lower lobe opacification (Fig 1), for which he is immediately admitted to the hospital for further evaluation. Figure 1. Chest radiograph shows left-sided pleural effusion, lower lobe opacification, and dilated loops of bowel. Initial vital signs include a temperature of 96.6°F (35.9°C) (axillary), respiratory rate of 30 breaths/min, heart rate of 140 beats/min, blood pressure of 108/56 mm Hg, and oxygen saturation of 98% on room air. He exhibits respiratory distress, with grunting, subcostal retractions, and diminished air entry in the left lung base. There is significant abdominal distention, with diffuse tenderness, normal bowel sounds, and tympanic percussion from the …
