Hysteroscopic morcelation of large type II myoma
Gynecological Surgery volume 12, pages267–269(2015)
Large uterine submucous fibroids can cause severe clinical symptoms, depending on size and location . The standard technique to remove uterine intracavitary abnormalities is resectoscopy . Electroresection is used to remove polyps, type 0 or I myoma <5 cm diameter, whereas type II myomas are commonly treated in more than one procedure [3, 6].
Hysteroscopic morcelation (HM) is a promising technique to remove myomas. HM reduces tissue by mechanical cutting into small fragments [2–4], whereas subsequent aspiration leads to tissue collection. Several studies indicated successful removal of myomas (type I or 0) and polyps by HM . Consistency of myomas can be a significant factor using morcelation. This communication describes the first successful morcelation of a soft 6-cm type II myoma.
A woman (39 years) visiting the outpatient Gynaecology Clinic2, complaining of heavy regular menstrual bleeding (HMB), revealed at diagnostic workup a 6-cm submucous uterine fibroid (Fig. 1a, b). Her history included four caesarean sections and a left salpingectomy. Leuprolide acetate showed no benefit. Hysteroscopic removal of the myoma was attempted by using the HM. The patient received misoprostol and antibiotics preoperatively and was counselled for multiple procedures. During an international workshop2, complete morcelation using HM (TRUCLEAR; Smith and Nephew, Andover, MA, USA) was performed, using a reciprocating 5-mm blade (Fig. 2). Intrauterine pressure of 100 mmHG, a rotary speed of 1400 rpm and a suction of 200 mm Hg was used to morcelate the intracavitary part of the myoma. The remaining intramural part was enucleated and morcelated manoeuvring the stiff blade between the myoma and the capsula. The procedure lasted 15.4 min with 450 cc fluid deficit. Finally, no adherent intracavitary remnants remained (Fig. 1c).
This communication describes a complete hysteroscopic morcelation of a soft 6-cm, type II myoma. Studies using HM describe safe resection of type 0 or I myomas [2, 3, 5]. HM is easy to perform, demonstrates less fluid-related complications and shows a shorter learning curve, compared to traditional resectoscopes [2, 3, 5]. Significant reduction in operation time may be due to simultaneous aspiration of tissue fragments rather than the removal of each individual fragment by using resectoscopy [1–3]. Risks of complications increase in type II myoma with increased intramural extension [6, 7]. Overall, success rates are lower with higher rates of incomplete resection, post-operative bleeding and reoperation .
Probably the soft tissue characteristics led to complete removal in a short operation time, with minimal fluid loss. There is more adaption of tissue into the beak of the device, and larger tissue fragments could be morcelated. The tip of the device is able to dissect the myoma out of its capsula. Despite the absence of electrical current, no excessive bleeding or other complications occurred which demonstrates the future opportunities of HM.
Furthermore, it could be of importance to examine the consistency of the myoma (e.g. using dynamic sonography and elastography) in the pre-operative assessment prior to hysteroscopic removal.
Morcelation of a type II myoma should be performed in select cases to optimize outcome with notice of the consistency of the myoma.
