مقایسه قطر اسکار آپاندکتومی بدون عارضه با برش راکی دیویس با قطر اسکار برش فن اشتایل در سزارین در زنان مراجعه کننده به بیمارستان شهید رجایی 1386- 1388

Backgroundformation which is probably due to amniotic fluid around the fetus, unique extracellular matrix andthe fetal immature immunity. It is supposed that biochemical and physical characteristics of amnioticfluid prepares the conditions for wound healing without scar formation. The goal of this study was tocompare the scar diameter of uncomplicated appendectomy by Rocky-Davis incision with scardiameter of cesarean section by Pfanneistiel incision in order to evaluate the effect of amniotic fluidon scar diameter.: According to some studies, fetal wound in contrast with adult wound heals without scarMethodsRocky-Davis incision who were pregnant or had history of cesarean in the last 18 months wereincluded (2007-2009). After 18 months of operation (appendectomy and cesarean), scar diameterswere measured in three points (first, middle and end of scar) and the mean was calculated. Then themean scar diameter of appendectomy was compared with the mean scar diameter of cesarean in eachpatient. For data analysis we used T-test, Paired T-test, correlation coefficient and regression tests.: In this analytic within-patient study all women with uncomplicated appendectomy byResultsdiameter of appendectomy was 2.09±0.677 millimeter and the mean scar diameter of cesarean was0.467±0.633 millimeter which was significantly less than appendectomy scar diameter (p= 0.008).: In this study the effect of weight and height on scar diameter was evaluated. Mean scarConclusionfuture scar diameter.: It seems that the presence of amniotic fluid in the first hours of healing decreases the
