A 61-year-old man presents to the emergency department with severe, unremitting right groin pain and nausea for the past 6 hours. He has vomited dark, foul-smelling fluid three times. He has a history of a right-sided groin bulge that he normally pushes back in, but since the pain started, he has been unable to do so. His temperature is 38.2°C (100.8°F), blood pressure is 110/70 mm Hg, heart rate is 115/min, and respiratory rate is 18/min. Physical examination reveals a distended abdomen with high-pitched bowel sounds. Examination of the right groin reveals a 5-cm, firm, exquisitely tender, and erythematous mass above the inguinal ligament. Laboratory studies show a leukocyte count of 16,500/mm³ and a serum lactate level of 3.8 mmol/L. Which of the following is the most appropriate next step in the management of this patient?
- ANasogastric tube decompression and serial abdominal examinations
