At laparotomy, sonohysterography was performed on 16 patients with endometrial adenocarcinoma. Volumes at which tubal spill occurred were recorded. Collected specimens were processed and incubated. After evaluation for viable cells, cytologic analysis was undertaken.
The median volume that was required for adequate sonohysterography was 8.5 mL. Five patients (31 % ) had transtubal spill. With an additional saline solution flush, the median total volume for a spill was 20.5 mL. Two patients (12.5 % ) had viable benign cells that were cultured after routine sonohysterography. One patient (6 % ) had nonviable carcinoma cells that were identified.
Transtubal spill occurs during sonohysterography. No critical spill volume was identified. A highly diagnostic tool when abnormal bleeding is evaluated, sonohysterography has a low probability of cancer cell dissemination.
