Jun Young Chung, Hyun Jyung Kim, Sam Beom Lee, Byung Soo Do
BACKGROUND: Acute appendicitis is very not uncommon disease and has many difficulties in the diagnosis of disease. So we should evaluate the significance of diagnosis by "MANTRELS" score which is very simple and easily accessible tools in patients of right lower quadrant abdominal pain.
We studied 164 patients initially complainted of right lower quadrant abdominal pain from Jan 1 to Jun 30. 1997 in emergency department of Yeungnam university hospital. At first, "MANTRELS" scores was calculated and we evaluated the final diagnosis, surgically operated or not, transferred or not, etc, retrospectively. Next, two groups were divided each that group A was surgically operated, group B was not surgically operated. And then the statistical significance and accuracy rate according to scores and cut-off values in each groups were evaluated.
All 164 patients was admitted in emergency department of Yeungnam University hospital and male to female ratio was 1:0.98, mean ages was 35.3 years old. The incidences according to each items of "MANTRELS" were as follows; most in Tenderness and Shift to left, Migration of pain in group A and most in Tenderness and Anorexia. Nausea in group B. As the results according to each scores in both group, score 8; 25 cases, score 7; 14 cases in group B were showed and the correlation coefficients was 0.979. And as the results according to cut-off value in both groups. it's sensitivity and negative predictability. false negative, positive joint probability were decreased and others were increased as the cut-off values, respectively. The diagnostic weight was most highest(75.0%) when the cut-off value was 7.
The authors would authorize that "MANTRELS" score is very simple scoring system and have diagnostic values in differentiating between acute appendicitis and other diseases complaining of right lower quadrant abdominal pain.
