PURPOSE: to evaluate the spreading of endometrial cells to the peritoneal cavity during diagnostic hysteroscopy. METHODS: a prospective, descriptive study involving 76 patients divided in two groups: one with 61 patients without malignant endometrial cancer, and the other with 15 patients with endometrial cancer. Two samples of peritoneal fluid were collected, one before (PF-1) and the other immediately after (PF-2) the diagnostic hysteroscopy. Spread to the peritoneal cavity was defined by the presence of endometrial cells in PF-2, with the absence of such cells in PF-1. The 5 mm diameter Storz’s hysteroscopy was used. Distention was obtained by CO2 with electronically controlled flow pressure of 80 mmHg. The PF was fixated in absolute alcohol (ratio1:1). The PF samples were centrifuged and aliquots were smeared and stained using the Papanicolaou method. Analyses were performed by the same observer. RESULTS: during the study, four patients (5.26%) were excluded for presenting endometrial cells in PF-1. In the remaining 72 patients, there was no spread of cells to the peritoneal cavity. In the non-endometrial cancer group, 88.1% (52/59) presented secretory endometrial phase, with correlation of 80% between the hysteroscopy and the biopsy. In the group with endometrial cancer, most of the patients were in stage I (92.3%). There was a 100% correlation between the hysteroscopy/biopsy and histopathology of the surgical sample. CONCLUSIONS: the diagnostic hysteroscopy with CO2 at flow pressure of 80 mmHg did not cause spread of endometrial cells to the peritoneal cavity in both groups, thus suggesting that the diagnostic hysteroscopy is safe for patients at high risk for endometrial cancer.
