Diagnostic hysteroscopy at King Chulalongkorn Memorial Hospital: 7 years experience.

We reported our experience and results of diagnostic hysteroscopy performed on 294 patients between June 1994 and May 2000 at the Gynecologic Endoscopy Unit, King Chulalongkorn Memorial Hospital. Diagnostic hysteroscopy was performed successfully in 286 patients (97.3%), allowing thorough inspection of the uterine cavity. Cervical dilatation was required in 146 patients (49.6%). The most common indication was endometrial polyps (34.4%) followed by infertility (19.4%) and abnormal uterine bleeding (14.9%), respectively. Each of the hysteroscopic findings accounted for 103 patients (35%) in endometrial polyps and normal endometrium. The procedure failed in 8 patients (2.71%) due to uterine perforation. In conclusion, diagnostic hysteroscopy should be considered as a safe, effective and successful investigation procedure for suspected intrauterine pathology.

Accuracy of hysteroscopic diagnosis of endometrial polyps.

OBJECTIVE: To evaluate the diagnostic accuracy of endometrial polyps by hysteroscopy. MATERIAL AND METHOD: One hundred and sixty five women undergoing diagnostic hysteroscopy between January 1996 and December 1998 at the Gynecologic Endoscopy Unit, King Chulalongkorn Memorial Hospital were recruited in this study. The hysteroscopic diagnosis was compared with the histopathology by endometrial curettages performed after hysteroscopy. RESULTS: Endometrial polyps were diagnosed by hysteroscopy in 54 patients (32.73%). When compared to tissue pathology, we found an accuracy of 81.21 per cent, sensitivity of 92.59 per cent, specificity of 78.98 per cent, positive predictive value of 46.29 per cent, negative predictive value of 98.19 per cent, false positive of 17.57 per cent and false negative of 1.21 per cent. CONCLUSION: For endometrial polyps, diagnostic hysteroscopy yields a high accuracy but low positive predictive value. Therefore, endometrial biopsy is necessary to confirm diagnosis of endometrial polyps by hysteroscopy.
