Use of Misoprostol in Hysteroscopic Myomectomy

Официальное название

Use of Misoprostol in Hysteroscopic Myomectomy, a Randomized Peospective Trial

Обзор

Hysteroscopic myomectomy is typically suitable for myomas measuring under 4 cm in size. The utilization of misoprostol before the procedure can facilitate uterine access, decrease fluid absorption, and reduce blood loss, consequently leading to a decrease in the overall procedure time. In this randomized trial, the investigators aim to investigate the impact of misoprostol administration and its effects on each of the mentioned parameters.

Подробное описание

Hysteroscopic myomectomy is a minimally invasive surgical procedure designed to remove uterine fibroids that are located within the uterine cavity. Traditionally, hysteroscopic myomectomy for large fibroids has been performed as a two-step procedure, with fibroid removal divided into separate stages. However, advancements in surgical techniques and equipment have allowed for the development of hysteroscopic myomectomy as a one-step procedure, in which all fibroids are removed in a single surgical session.

As a one-step procedure, hysteroscopic myomectomy offers several potential benefits. It eliminates the need for multiple surgeries and reduces the overall treatment timeline for patients. The size limit for hysteroscopic myomectomy varies among surgeons and institutions. In general, submucosal fibroids up to 4 centimeters in diameter are considered suitable for hysteroscopic resection.

Fluid overload is an important consideration in hysteroscopic myomectomy, especially when it is performed as a one-step procedure, making it a time-limited procedure. During hysteroscopic myomectomy, a distension media is used to expand the uterine cavity, providing better visualization and creating a working space for the surgeon. However, there is a risk of fluid overload if excessive fluid is absorbed into the bloodstream, potentially leading to complications such as electrolyte imbalances, fluid imbalance, hyponatremia, or cardiovascular issues. To mitigate this risk, certain precautions are taken during the procedure.

When the uterus contracts, the fibroid may undergo several changes. These changes can affect the position, size, and accessibility of the fibroid, potentially influencing the surgical approach and outcome. Fibroid extrusion occurs when the fibroid becomes detached from its attachment site and is pushed out of the uterus by the uterine contractions.

A case study published by Murakami et al. discussed the contributing effect of intraoperative injection of prostaglandin F2 alpha in a patient undergoing hysteroscopic myomectomy, resulting in a successful one-step hysteroresectoscopy of a sessile submucous leiomyoma . Additionally, Indman described the effect of intracervical injection of carboprost prior to hysteroscopic resection of submucous myomas that could not be completely resected in a series of 10 case studies .

To the investigators knowledge, the use of misoprostol in hysteroscopic resection has been primarily limited to its role as a cervical dilation primer prior to the procedure. The use of misoprostol in hysteroscopy may reduce the need for mechanical cervical dilatation , however, many centers do not use misoprostol routinely in every hysteroscopy.
