title: Psychomotor testing and the ability to perform an anastomosis in junior surgical trainees.
abstract: Ten junior surgical trainees underwent objective testing of manual dexterity and visuospatial ability and were required to carry out five consecutive anastomoses on fresh porcine jejunum. Anastomoses were scored by a single observer and a cumulative error score (CES) derived for each procedure. In the first anastomosis there was little correlation between the psychomotor test results and the anastomosis scores. In subsequent trials there were significant negative correlations between aspects of manual dexterity and the CES. Over the five anastomoses there were significant negative correlations between improvement and manual dexterity, but there was a positive correlation between improvement and visuospatial ability (rs = 0.76, P < 0.005). Visuospatial skills are more important than pure motor ability in predicting the capacity to perform an anastomosis and tests of manual dexterity may be misleading in this context.
