RESUMEN
STUDY OBJECTIVE: Because postmenopausal bleeding (PMB) is associated with up to 10% of endometrial neoplasia and office endometrial sampling fails in approximately 10% and is inadequate in 30% of cases, the objective was to determine the role of hysteroscopic endometrial resection (HER) for the diagnosis and treatment of women with PMB. DESIGN: A retrospective cohort. SETTING: A university-affiliated teaching hospital. PATIENTS: One hundred fifty-one women with PMB (September 1990-December 2010). INTERVENTION: HER in the operating room. MEASUREMENTS AND MAIN RESULTS: The median (range) age and body mass index were 58 (50-87) years and 29 (21-52) kg/m2, respectively. Office endometrial biopsy failed in 30 (19.8%), was inadequate in 20 (13.2%), identified nonatypical endometrial hyperplasia (NAH) in 21 (14%), atypical hyperplasia (AH) in 4 (2.6%), and endometrial cancer (EC) in 2 (1.3%) women. HER in 151 women identified 7 new cases of AH (3 from failed/inadequate office biopsy and 4 from NAH) and 9 EC (5 from failed/inadequate office biopsy, 1 from proliferative endometrium, 2 from NAH, and 1 from AH). All 27 women with NAH were treated by HER alone. Of 8 women with AH, 6 were treated with HER and 2 with hysterectomy; no residual endometrium was found in hysterectomy specimens. Of the 11 women with EC, 2 refused hysterectomy and are well 10 and 15 years after HER. Hysterectomy was performed for 9 of 11 EC cases, 2 of 8 AH cases, and 1 for abnormal uterine bleeding. Six women had repeat HER for persistent abnormal uterine bleeding, and 10 were lost to follow-up. At a median follow-up of 11.5 years (range, 7-20 years), 132 (12 hysterectomiesâ¯+â¯10 lost) of 151 (87.4%) women were satisfied with no further bleeding. CONCLUSION: In women with PMB, hysteroscopic endometrial resection concomitantly with resection of intrauterine pathology by experienced surgeons is feasible, safe, and effective for diagnosis in all cases and treatment of the majority of intrauterine pathology including NAH and selected cases of AH and EC.

Aims. Our aim is to compare the adequacy and diagnostic yield of samples obtained by the endometrial Explora Sampler I-MX120 with endometrial specimens obtained by conventional dilatation and curettage (D&C). Methods. A total of 1270 endometrial samples were received in the histopathology laboratories at the King Khalid University Hospital, Riyadh, Saudi Arabia, between 2007 and 2010. In the outpatient clinic, the Uterine Explora Model I was used to obtain 996 samples. The remaining 274 samples were obtained by conventional D&C. Sample adequacy and the clustering of inadequate specimens according to age groups by the two different techniques were compared and statistically analyzed. Results. Out of 1270 endometrial samples, 253 (19.9%) were inadequate. The Uterine Explora was used in 88.5% of these inadequate samples (253 samples), and the remaining 11.5% were obtained by D&C. The insufficient tissue incidence was higher with the Explora (17.6%) than with the D&C (2.2%) and the difference was statistically significant (P < 0.0001). The ages of the patients, as well as the clinical indications for the procedures, were recorded. Conclusion. This retrospective study demonstrated better specimen adequacy when D&C was used compared to the higher rate of sample insufficiency obtained with the Explora.
