To evaluate whether the presence of a visualizable "flow" effect in the fallopian tube ostia in hysteroscopy was predictive of tubal patency.. A prospective cohort study.. In a prospective study, infertile women who underwent surgery because of infertility between March and November 2018 were included. The main outcome parameter was fallopian tube patency assessed by laparoscopic chromopertubation. The predictive parameter tested was the presence of hysteroscopic tube flow.. Seventy-two infertile women.. Combined hysteroscopy and laparoscopy with chromopertubation.. One-hundred forty-four fallopian tubes were evaluated, with 88 (61.1%) patent tubes at laparoscopic chromopertubation. A positive hysteroscopic flow effect was recorded for 94 (65.3%) ostia and was accurate in predicting patency (p < .001), with a sensitivity of 85.3% (95% confidence interval [CI], 76.1-91.9) and a specificity of 66.1% (95% CI, 52.2-78.2). A multivariate binary regression model revealed that the presence of a hydrosalpinx (odds ratio = 8.216; 95% CI, 1.062-63.574; p = .044) and peritubal adhesions (odds ratio = 3.439; 95% CI, 1.142-10.353; p = .028) were associated with a false-normal flow result. A hazy hysteroscopic picture was found in 15 of 21 (71.4%) and 5 of 51 (9.8%) cases with and without bilateral tubal occlusion, respectively (p < .001, sensitivity = 71.4% [95% CI, 47.8-88.7], specificity = 90.2% [95% CI, 78.6-96.7]).. The presence of hysteroscopic tubal flow was a reliable indicator of tubal patency. A hydrosalpinx or peritubal adhesions increase the risk for a false-normal result. A hazy hysteroscopic picture suggests bilateral tubal occlusion. Using the hysteroscopic flow effect, one can provide additional information for the patient.

Diagnostic techniques for oviductal obstruction in the mare are limited and development of a more reliable and direct method to assess oviductal patency is needed.. To evaluate the feasibility of hysteroscopic selective hydrotubation of the equine oviduct via videoendoscopy in standing mares.. Using a catheter inserted under endoscopic guidance into the uterotubal junctions of 10 mares, 5 ml of indigo carmine solution (4 mg/ml) was flushed into the oviduct. After introduction of the dye, peritoneal fluid was obtained via abdominocentesis. A colpotomy was also performed to allow introduction of a videoendoscope into the abdominal cavity to assess the presence of dye visually at the ovarian end of the oviduct.. In 15 of 20 (75.0%) attempts, the catheter was successfully inserted into the uterotubal junction, and dye was observed at the ampulla, fimbria, overlying the ovary or surrounding tissue. In 2 mares, the videoendoscope could not be manipulated to identify the uterotubal junction. Only one of 2 oviducts was flushed in an additional mare because insufflation of the uterus could not be maintained. The colour of the dye was evident macroscopically and spectrophotometrically in 4 of 8 mares from which peritoneal fluid was successfully collected.. The equine oviduct can be evaluated by hysteroscopic selective hydrotubation.

The aim of this study was to determine whether autologous erythrocyte suspension can be used as a dye for evaluation of tubal patency and whether it has any advantages over methylene blue or indigo carmine solutions. Reproductively healthy female nulliparous Wistar Albino rats (n = 30), aged 6 months, mass 165-195 g, were assigned randomly to three groups. Rats received a 1 ml i.p. injection of 5% (w/v) methylene blue solution (methylene blue group: n = 10), 5% (w/v) indigo carmine solution (indigo carmine group: n = 10) or 5% (v/v) fresh autologous erythrocyte suspension (autologous erythrocyte group: n = 10). At 4 weeks after injection, a small sterile opening was made in the peritoneal cavity of each rat. The cavity was rinsed once with TCM-199 to collect macrophages. The rinsed peritoneal contents were cultured overnight to evaluate macrophage activation. The peritoneal opening was expanded for evaluation of adhesion formation. Only one rat from the autologous erythrocyte group had intra-peritoneal adhesions (score 2), whereas all rats in the methylene blue group (score 1: n = 1; score 2: n = 4; score 3: n = 4; and score 4: n = 1) and seven rats in the indigo carmine group (score 1: n = 1; score 2: n = 2; score 3: n = 3; and score 4: n = 1) had intra-abdominal adhesions. Macrophage activity was observed in the cultured peritoneal contents collected from the methylene blue and indigo carmine groups but not from the autologous erythrocyte group. Adhesion formation could be due to macrophage activation caused by methylene blue and indigo carmine solutions. These results indicate that tubal patency can be observed by laparoscopy using autologous erythrocyte suspension. The results of this study are believed to be the first to indicate that a patient's own erythrocyte suspension could be used during observation of tubal patency by laparoscopy. However, further studies are required.
