Diagnostic value of high-frequency ultrasound in the diagnosis of abdominal wall incision endometriosis

Objective To investigate the diagnostic value of high-frequency ultrasound in abdominal wall incision endometriosis.Methods Twenty-five cases(24 cases after caesarean section,1 case after chocolate cyst exsection) which were suspected as endometriosis of abdominal wall incision in the clinic were examined by high-frequency ultrasound and the sonogram characters were analyzed.Results All cases were confirmed as endometriosis of abdominal wall incision by patho-operations or biopsy-puncturations.There were obscure boundary,anomal-morph,interior inhomogeneous and low echo-level masses in the sonogram characters.Color doppler flow imaging showed that there was punctiform or trabs blood flow signal in the perimeter of the masses and no blood flow signal in the interior in 21 cases,and there was semiring blood flow signal in the perimeter and punctiform blood flow signal in the interior in 2 cases,and there was no blood flow signal in the perimeter and in the interior in 2 cases.Pulse doppler(PW) showed artery frequency spectrum of low speed(Vs 5.4-19.2 cm/s) and high resistance(RI 0.71-0.85).Conclusion Combined with the clinical datun,high-frequency ultrasound has high consistent rate and very important clinical application value in the diagnosis of abdominal wall incision endometriosis.
