Pilonidal sinus is a common disabling condition of young adults. Many
different operative treatments have been suggested, the ideal treatmen
t is, therefore, controversial. As the recurrence rate for the various
procedures is similar, avoidance of a general anaesthetic, minimal in
patient stay, and minimal inconvenience and time off work become impor
tant considerations. We present our experience with excision and prima
ry closure in 46 patients over a 4-year period. Half the patients had
a general anaesthetic, the other half a spinal anaesthetic. Average du
ration of inpatient stay was 1 day. Early complications (haematoma, wo
und infection, and minor wound breakdown) occurred in 8%. Early pain w
as less of a feature after the use of bupivacaine infiltration at the
end of the operation. There were 40 patients available for follow-up,
with an average of 3 weeks off work and a recurrence rate of 17.5%. Of
these patients, three have had the recurrence treated with no further
problems.
