Classic yet challenging case of stump appendicitis: a case report

Introduction: Stump appendicitis is a rare complication of appendectomy in which residual appendiceal tissue becomes inflamed, mimicking acute appendicitis. This case report highlights the classic clinical presentation, diagnosis, and management of stump appendicitis. Case presentation: A 61-year-old male presented with abdominal pain and a past history of open appendectomy performed 4 years prior. Clinical examination, laboratory, and radiological findings were highly suggestive of stump appendicitis. Surgical exploration confirmed an inflamed appendiceal stump, which was resected, and the patient had an uneventful recovery postoperatively. Discussion: Stump appendicitis is a rare but important differential diagnosis in patients with a history of appendectomy who present with acute abdominal pain. Delayed diagnosis can result in complications such as perforation and peritonitis. Imaging plays a crucial role in diagnosis, and surgical resection, typically performed through open-completion appendectomy, remains the treatment of choice. Conclusion: Although stump appendicitis is rare, it should always be considered in patients with a prior appendectomy who present with acute abdomen. Early recognition and prompt surgical intervention are essential to prevent morbidity and mortality.
