Year 4niche
A 72-year-old woman with a BMI of 30 presents with a tender right groin lump that has become irreducible over the past 6 hours. She reports mild nausea but no vomiting. On examination, the lump is located below the inguinal ligament and is firm, tender, and non-reducible. She underwent an open appendectomy 40 years ago via a lower midline incision. Blood tests are unremarkable.
What is the most appropriate management strategy?
