RESUMO
OBJECTIVE: Appendicitis is the most common abdominal emergency usually requiring surgery in the pediatric age group. Diagnosis of acute appendicitis can at times be difficult, especially in children. A failure to diagnose can lead to a progression of disease with its associated morbidity and mortality. The authors used a modification of Alvarado scoring system which consists of eight variables and would provide an accurate guide to the preoperative diagnosis of acute appendicitis leading to proper and timely management. METHODS: This was a prospective study conducted from Jan 2005 through Dec 2006 and included 90 consecutive patients with suspected acute appendicitis. They were given specific scores according to variables of scoring system and divided into 3 groups. Group III patients (score 7 or more) underwent surgery, group II (score 5-6) were admitted for close observation and group I (score 4 or less) were discharged home. Patients from group II with increased symptom intensity (score 7 or more) on re-evaluation underwent surgery. Diagnosis was confirmed by operative findings and histopathological examination. Reliability of scoring system was assessed by calculating negative appendicectomy rate and positive predictive value. RESULTS: Out of total 90 patients, 73 patients underwent surgery and appendicitis was confirmed in 68 cases. The negative appendicectomy rate was 6.84%, perforation rate was 36.9%. Positive predictive value was 93.1%. CONCLUSIONS: Our scoring system is useful as a first line, rapid, reliable and economic way of early preoperative diagnosis of acute appendicitis in children and in reducing the incidence of negative appendicectomy rate.

Sixtynine patients (31 males and 38 females) above the age of 12 years undergoing surgery under general anaesthesia were selected for this study. Thirty percent males and 29% females were depleted, 55% and 37% males and females, respectively, were normal and 13% and 34% males and females, respectively, were obese as indicated by Body-mass index (BMI). Measurement of midarm-muscle-circumference (MAMC) indicated mild to moderate protein deficiency in 32% of the patients while triceps skinfold thickness (T.S.T) indicates mild to severe calorie deficiency in 68% males and 50% females. Dietary intake both pre and post operatively was unsatisfactory. Pre-operatively 26% of the females had Hb level below normal (less than 11 G%). Only 3-5% of the patients had protein and albumin level below normal (less than 3.5 G%). Post-operatively all the anthropometric measurements as well as serum protein and albumin levels decreased and BUN increased significantly indicating body catabolism. Post operative hospital stay was significantly more in undernourished patients.
