Accuracy of palpation and percussion manoeuvres in the diagnosis of splenomegaly.
A study was conducted on 80 patients admitted in a teaching hospital to see the accuracy of two palpatory methods (Supine palpation and Middleton's manoeuvre) and three percussion methods (Traube's space percussion, Castell's and Nixon's manoeuvres) in the diagnosis of splenomegaly. Ultrasonographic findings were considered as gold standard for diagnosing splenomegaly. Mean age of study subjects was 31.5 years and mean Quetelet's index was 17.8 +/- 2.6 kg/m2. Sensitivity of Middleton's and Castell's manoeuvres was similar (85.7%) and higher than other manoeuvres. Nixon's manoeuvre had the least sensitivity (66.7%). Specificity was highest (92.1%) with supine palpation and least (31.6%) with Castell's manoeuvre. Supine palpation showed highest positive predictive value (91.7%). Receiver Operating Characteristics curves showed greater area with middleton's manoeuvre (0.93) followed by supine palpation (0.92), Castell's manoeuvre (0.75) and Traube's space percussion (0.74), the findings of the study suggests that palpatory methods like Middeton's manoeuvre and Supine palpation should be routinely used for diagnosing splenomegaly among non-obese individuals.
