[New in hysteroscopy: hysteroscopic morcellators]. / Nouvelle technique en hystéroscopie : les morcellateurs hystéroscopiques.

A new technology recently appeared for the treatment of endo-uterine pathologies: hysteroscopic morcellators. It seemed to us useful to review this new technology. The morcellator we mostly experiment is the Myosure®, in 14 patients, with a median age of 40.5 years (28-58). The time of procedure went from 5 to 75 min with a median time at 26 min. The median of the total fluid deficit was 300 mL (0-1500 mL). A conversion in traditional resectoscopy happened in 4 cases (29%). This results are not so good as in literature. This is probably bound to one the learning curve but also the type of pathology. For the operative time, all the studies agree that hysteroscopic morcellation is faster than hysteroscopic resection. The quantity of fluid used is also lesser, as the deficit of fluid when the morcellator is used. The percentage of success to remove the pathology is high, close to 100% for the polyps and 92% for the submucous myomas. The indications are the polyps and the submucous myomas type 0 or 1. The morcellation of remnant trophoblastic tissues is also described and seems effective. Others indications, as the removal of uterine septum or cure of uterine synechias, are criticisable. In conclusion, hysteroscopic morcellators are probably a great progress for the cure of the endo-uterine pathologies. They cannot yet concurrence the hysterosopic resectoscopes for the treatment of big submucous myoma or those with a large intramyometrial involvement.

[Long-term complication of laparoscopic uterine morcellation: iatrogenic parasitic myomas]. / Complication à long terme du morcellement utérin par voie cœlioscopique: les myomes parasitiques iatrogènes.

OBJECTIVES: Identify parasitic myomas following uterine laparoscopic morcellation and describe the circumstances of diagnosis, management, potential consequences and possible preventive measures. METHODS: Retrospective study of observed cases in a university hospital between 2000 and 2012 and review of the literature. RESULTS: Five cases were identified in our department. Pelvic pain was the main symptom in three patients while one was asymptomatic and one consulted for a cystocele. The average time to diagnosis was 88 months (3-192). Surgical removal was performed in four cases by laparoscopy and vaginally for one case. Histological examination showed typical leiomyomas, but in one case, an atypical leiomyoma with limited experience for a typical primary lesion. In the literature, there are about 50 cases. One required a bowel resection and for another one, after subtotal hysterectomy, histological examination showed complex atypical endometrial hyperplasia for normal endometrium initially. CONCLUSIONS: This study should draw the attention of laparoscopic surgeon. It emphasizes, beyond a potential reoperation, a risk of atypical histological secondary processing. Surgical resection should be discussed even in case of asymptomatic lesions.
