The etiology and developmental process of hypertrophic scar and keloid
are unclear, therefore, it is important to make effort to prevent and
treat these lesions at an early stage. The lower abdominal region is
known as a site at which postoperative abnormal scars are easy to
develop.
Since May 2006, we have started an outpatient clinic that examines
postoperative scars after obstetrical and gynecological operation. The
aim of this study was to classify the types of scars at one month
postoperative and determine the frequency of abnormal scars such as
hypertrophic scars and keloids one year after operation.
There were 6 types of postoperative scars that were classified on the
basis of the scar condition at one month postoperative.
The frequency of development of postoperative hypertrophic scar at 1
year was 22.9% and that for keloid was 2.55%.
There were differences in the frequency of development of hypertrophic
scars and keloids among different types of scars one month
postoperative.
It was revealed that it is important to check the scar condition at one
month postoperative, and decide whether treatment is needed to prevent
abnormal development of scars.
