Risk of malignancy on suspicion of polyps in menopausal women.

Improved performances in gynaecological ultrasonography have enabled an increasing number of often asymptomatic endometrial polyps to be detected. Most of these polyps are removed surgically, as a precautionary measure, so as not to miss a case of endometrial cancer. Nonetheless, this management strategy is based solely on the sonographer's judgement and a number of these operations, which are probably of no benefit, could be avoided. In order to do so, risk factors for malignancy need to be identified. OBJECTIVE: Estimate the prevalence of lesions in menopausal patients with a pre-operative diagnosis of endometrial polyp. Establish risk factors for malignancy. STUDY DESIGN: This is a single-centre retrospective study. Enrolment criteria were menopausal patients aged over 45 who had undergone hysteroscopic resection of a polyp. Pre-op diagnosis was made either by ultrasonography or diagnostic hysteroscopy. Malignant lesions included cancers and atypical hyperplasia. Benign lesions consisted of simple polyps, non-atypical simple hyperplasia and non-atypical complex hyperplasia. Risk factors studied were existing abnormal uterine bleeding, endometrial thickness, personal or first-degree family history of gynaecological cancer (breast, cervix, endometrium, ovary) and age on diagnosis. RESULTS: 631 patients were enrolled of whom 30 presented a malignant disorder (4.75%); 579 patients (91.76%) presented a simple polyp, 11 a non-atypical simple hyperplasia (1.74%) and 11 a non-atypical complex hyperplasia (1.74%). On univariate analysis age alone proved to be statistically significant (OR 1.05; 95%CI=[1.02-1.09] p<0.01), with a threshold of 59 years of age on the ROC curve. On multivariate analysis, factors predictive of a malignant lesion were age (OR=1.06; 95%CI [1.02-1.10]), existence of AUB (OR=2.4; 95% CI [1.07-5.42]) and family history (OR=2.88; 95%CI [1.08-7.67]). Neither the univariate nor multivariate model was able to demonstrate a statistically significant relationship with respect to endometrial thickness. The risk of malignancy was 12.3% in patients aged over 59 presenting AUB. For all other subgroups, the risk varied between 2.31 and 3.78%. CONCLUSION: The risk of a malignant lesion appears to be high (12%) in menopausal patients aged over 59 presenting an endometrial polyp detected when there is pre-existing AUB. In this situation, hysteroscopic resection of endometrial polyps should therefore be routinely proposed. For other patients, the risk of a malignant lesion is low but not insignificant, standing at about 3%. Each patient record should therefore be discussed on an individual case basis, taking into consideration the patient's pre-existing conditions, after providing clear and appropriate information.

Treatment of a Fetal Tracheal Obstruction by Fetoscopy and Laser.

We report below a case of in utero tracheoscopy with laser collapse of a bronchogenic cyst obstructing the fetal trachea. The patient was referred for ultrasonography at 24 weeks of gestation because of fetal hydrops. Tracheoscopy was performed via fetoscopic approach using a single trocar under local anesthesia with lidocaine and ultrasound guidance. This revealed an image suggestive of a cyst obstructing the middle third at the anterior base of the trachea. Coagulation using a diode laser enabled us to collapse this fluid-filled cyst with three 10-watt bursts (3 times 3 s) and to visualize a completely unobstructed tracheobronchial tree with significant pulmonary fluid reflux on removal of the obstacle. The fetal condition improved markedly within 48 h after the procedure. To the best of our knowledge, this is the first described case of in utero treatment of a tracheal obstruction by tracheoscopy and laser. In severe cases of obstruction of the fetal airways, whether the obstacle is situated in a high or low position, fetal endoscopy is of diagnostic and potentially therapeutic utility.
