Suppurative appendicitis at colonoscopy
Publication History
Publication Date:
19 March 2010 (online)
A 65-year-old man came to our emergency department with complaints of diffuse abdominal pain and a change in bowel habits for the past 4 days. He denied nausea, vomiting or fever. His medical history included diabetes mellitus, arterial hypertension, cerebral stroke, and ischemic heart disease. He had no past surgical history. On presentation, he was in good general condition and the abdomen was soft, depressive, with diffuse discomfort on palpation in the right upper quadrant, but without Blumberg sign. Laboratory tests showed leukocytosis (11|700/µL), hemoglobin at 14 g/dL, and C-reactive protein at 8.7 mg/dL (normal range < 1.0 mg/dL). Abdominal radiography and ultrasonography were normal. He was admitted with suspicion of diverticulitis.
He was still complaining of pain 5 days later, despite analgesia medication. A colonoscopy was performed, which showed a suppurative appendicitis ([Fig. 1]).

After the procedure, surgical consultation was immediately requested and an abdominal computed tomography (CT) was performed. CT scan revealed an inflammatory mass with gas inside the right lower quadrant, without free peritoneal liquid. The patient underwent appendectomy and abscess drainage, and postoperative recovery was uneventful.
The diagnosis of acute appendicitis is based on clinical criteria, corroborated by laboratory data and image findings [1]. However, some situations have subtle or atypical presentations and the role of colonoscopy has been shown to be particularly useful in these situations [1] [2] [3].
