Key result
Visuospatial ability positively correlated with improvement in performing anastomoses (rs=0.76, P<0.005), indicating it is more important than pure motor ability in predicting surgical capacity.
Why the study?
Does visuospatial ability or manual dexterity predict the capacity to perform an anastomosis and improve over time in junior surgical trainees?
Observational (n=10)

Visuospatial skills are more important than pure motor ability in predicting the capacity to perform an anastomosis and improve over time.
Visuospatial testing may aid trainee selection for anastomosis skills; leaves open prospective validation in surgical curricula.
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.

Steele et al. (1992) conducted an observational in Junior surgical trainees (n=10). Psychomotor testing (manual dexterity and visuospatial ability) was evaluated on Correlation between improvement in anastomosis cumulative error score and visuospatial ability (rs 0.76, p=<0.005). Visuospatial ability positively correlated with improvement in performing anastomoses (rs=0.76, P<0.005), indicating it is more important than pure motor ability in predicting surgical capacity.
