Thermography and diagnosis of appendicitis

Thermography and diagnosis of appendicitis

Acute appendicitis is a life-threatening pathology that requires urgent surgical intervention (Ferris, M., et al., 2017). This diagnosis remains challenging because its clinical presentation can be atypical and symptoms often overlap with other conditions that may or may not need surgical treatment (Ramirez-GarciaLuna, J. L., et al. 2020).

Recently, a study (Ramirez-GarciaLuna, J. L., et al. 2020) has evaluated skin infrared thermal imaging as a diagnostic adjunct for acute appendicitis in adults. For this purpose, they analyzed 51 patients with appendicitis, 20 with abdominal pain (no appendicitis) and 51 healthy controls.

They identified that abdominal region temperature <34°C discriminate healthy controls and patients with acute abdomen pain. Among this last group, a thermal asymmetry of the right abdominal region vs left abdominal region >0.35°C discriminate patients with and without appendicitis These results support that infrared thermography could be an adjunct tool in the diagnosis of appendicitis in locations with limited resources.
