Adhesion-induced chronic abdominal pain: a case report on the diagnostic value of Carnett's test

Tsunetaka Kijima et al. J Med Case Rep. .

Abstract

Background: Chronic abdominal pain is a common clinical problem. However, diagnosing chronic abdominal pain often requires detailed diagnostic evaluations in addition to sufficient history taking and physical examination, owing to its uncertain etiology.

Case presentation: We report a case of a 36-year-old man with chronic abdominal pain originating from postoperative adhesions. Postoperative adhesions are common phenomena, and abdominal surgery can cause severe abdominal pain, the source of which can be difficult to detect. Carnett's test is useful to detect abdominal wall tenderness and to determine the affected abdominal quadrant. Incorporating its use with a detailed chronological clinical history contributes to the improvement of diagnostic accuracy. In addition to the above-mentioned information, attention to subtle imaging findings may provide greater diagnostic accuracy.

Conclusions: Abdominal pain induced by postoperative adhesions was reduced by laparoscopic adhesiolysis. Carnett's test is an effective tool for evaluating pain and detecting its cause.

Keywords: Adhesion; Carnett’s test; Chronic abdominal pain.
