Purpose: “Chromoendoscopy” results in 34 recurrent miscarriage (MR) patients in whom conventional hysteroscopy did not show any apparent endometrial pathology. Method: 5 ml of 1% methylene blue dye was introduced through the hysteroscopic inlet. Results: The study group was classified according to the staining characteristics. Group I included 19 patients in whom focal dark staining was observed. Group II included 15 patients in whom diffuse light blue staining was observed. There was no significant difference between the two groups in age, smoking, status, BMI, number of miscarriages and in mean gestational age of the miscarriages. Time to hysteroscopy after the last miscarriage was shorter in Group I (63.9 vs 95.3 days). Then, the study group was classified according to the histopathology result. Group I included ten cases of endometritis while Group II included 24 cases with a normal histopathology. The mean number of miscarriages was higher in Group I (3.4 vs 2.5). Conclusion: Chromohysteroscopy improves the efficacy of hysteroscopy in RM cases and is warranted after three miscarriages in two cycles time.
