BACKGROUND: The current literature and guidelines are largely silent regarding the contribution of the fallopian tubes to the fluid deficit (FD) during hysteroscopy. We explored whether the FD could be in part due to transtubal passage.
METHODS: This was a prospective cohort study. Patients who underwent hysteroscopy because of benign gynecologic pathology with, or without, laparoscopy were enrolled. The fluid deficit and, in laparoscopic cases, the amount of fluid found in the pelvis were prospectively reported.
RESULTS: Comparisons between FD and intraperitoneal fluid were performed. Sixty-five patients were included in the study. Forty-five underwent hysteroscopy prior to laparoscopy and 20 patients underwent hysteroscopy-only. These were further divided into operative hysteroscopy and diagnostic hysteroscopy subgroups. In the laparoscopy group, the average FD was 525.9 mL (95% CI: 482.1-569.7) and the calculated FD due to intravasation was 286.6 mL (95%CI: 253.0-320.3). In the hysteroscopy without laparoscopy group, the average FD was 303.0 mL (95% CI: 85.2-520.8). There was no correlation between the intrauterine fluid pressure and the amount of FD, or the presence of intraperitoneal fluid.
CONCLUSIONS: Most women with patent tubes undergoing hysteroscopy have accumulation of distention fluid in the pelvis and that the passage was not correlated with the intrauterine fluid pressure. These findings add new insight to the current guidelines, suggesting more accurate and patient-centered safety protocols.
