APPRAISAL OF MODIFIED ALVARADO SCORE FOR ACUTE APPENDICITIS IN NIGERIA ADULTS
Abstract
Decision making in cases of acute appendicitis may be difficult experience in Nigeria where the
facilities for investigations are lacking. Modified Alvarado score (MASS) was very important in
diagnosis and treatment of patients with acute appendicitis seen in a semi rural area of Lagos
Nigeria.
Method: All adult patients aged 16 and above who were seen with a provisional diagnosis of
acute appendicitis between January 2012 and December 2014 were included in the study. There
were 35 males and 23 females. The 58 patients were evaluated on admission using modified
Alvarado score to determine whether they have acute appendicitis. The Alvarado score was
compared with the operative and histology results.
Results: Fifty eight patients were operated. The operative findings showed 51 (87.9) has positive
result for acute appendicitis. While 7 (12.1) had negative findings. However the histology shows
44 (75.9) with features of acute appendicitis and 14 (24.1) were negative.
Conclusion: The above results shows modified Alvarado score is very sensitive in diagnosis of
acute appendicitis in our environment. It is a very useful tool in absence of facilities in diagnosis
of acute appendicitis.
