They are proliferations of smooth muscle cells of the myometrium containing a large quantity of extracellular matrix and they are surrounded by a pseudo capsule of compressed areolar tissue and smooth muscle cells. They can cause various symptoms such as menorrhage, pain and infertility and therefore they can be a traumatic experience for several women. The treatment of choice is myomectomy. In the past, myomectomy was performed by relatively atraumatic techniques, which involved stretching the myoma from its pseudocapsule to extract the fibroid directly from the surrounding fibromuscular tissue, breaking up the fibrous bridge. Modern laparoscopic intracapsular myomectomy (LIM), however, leaves the fibrovascular network surrounding the myoma (namely the “fibroid neurovascular bundle”) intact which reduces the bleeding and/or uterine musculature trauma, and spares the neuropeptide fibers of the pseudocapsule. In this observational study, we compare the two techniques-laparoscopic intracapsular myomectomy (LIM) and conventional abdominal myomectomy (CAM) regarding the longterm uterine healing and a significantly faster healing process of the uterine incision was achieved by LIM compared to CAM.展开更多

A large sample study is necessary to assess the proportion of uterine malignant tumors found in patients with laparoscopic myomectomy. Methods： A national multicenter study was performed in China. From 2002 to 2014, 33,723 cases were retrospectively selected. We calculated the prevalence and recorded the clinical characteristics of the patients with malignancy after morcellation application. A total of 62 cases were finally pathologically confirmed as malignant postoperatively. Additionally, the medical records of the 62 patients were analyzed in details. Results： The proportion of postoperative malignancy after morcellation application was 0.18% （62/33,723） for patients who underwent laparoscopic myomectomy. Nearly 62.9% （39/62） of patients had demonstrated blood flow signals in the uterine fibroids before surgery. And, 23 （37.1%） patients showed rapid growth at the final preoperative ultrasound. With respect to the pathological types, 38 （61.3%） patients had detectable endometrial stromal sarcoma, 13 （21.0%） had detectable uterine leiomyosarcoma, only 3 （3.2%） had detectable carcinosarcoma, and 5 （8.1%） patients with leiomyoma had an undetermined malignant potential. Conclusions： The proportion of malignancy is low after using moreellation in patients who undergo laparoscopie myomectomy. Patients with fast-growing uterine fibroids and abnormal ultrasonic tumor blood flow should be considered for malignant potential, and morcellation should be avoided.展开更多
