Here, we present a protocol for performing an intracapsular rotary-cut procedure (IRCP), a modified laparoscopic intracapsular myomectomy that promotes fertility preservation.

Uterine fibroids are common benign tumors in the female reproductive system. A hysterectomy is the most effective treatment for symptomatic fibroids. For patients desiring pregnancy, laparoscopic intracapsular myomectomy (LM) is an alternative surgery option. Although LM is widely accepted to treat fibroids, it is technically demanding with risk of excessive bleeding and difficult suturing, especially in cases with large fibroids or tumors in unusual locations. Therefore, we developed an intracapsular rotary-cut procedure (IRCP) as a modification of laparoscopic intracapsular myomectomy, with the intention to minimize risks of LM and help uterine healing. A summary of the improvements to the IRCP is described: 1) making an incision at the site of the fibroid with a length of one-third to one-half of the fibroid's diameter at a depth reaching the fibroid's surface; 2) holding the fibroid stably and making rotary cuts on the fibroid at a depth of 0.5–1 cm within its pseudo-capsule while pulling it outward slightly, making sure not to cut off any pieces of the fibroid; and 3) repeating the cutting-and-pulling until the longest dimension of the fibroid is outside the incision. The multiple cuts are to minimize the diameter and extend the length of the fibroid. When the multiple cuts cause half of the fibroid body to "shrink", the fibroid is squeezed out by contraction of the surrounding myometrium. Evaluation of the outcomes of IRCP showed that the time of enucleation and suturing, intraoperative bleeding, and decline of hemoglobin were significantly lower in the IRCP group than the LM group. As for reproductive outcomes, the full-term live birth rate of the IRCP group was significantly higher than that of LM group. However, there was no difference in delivery modes between the two groups. In conclusion, IRCP significantly benefits fertility preservation by minimizing damage to the uterus, protecting myofibers of the pseudo-capsule, and resulting in a shallower residual cavity, which eases stitching and causes less bleeding. It is worthwhile to adopt IRCP in younger patients who desire preservation of their fertility.

Uterine fibroids are the most common pelvic tumors observed in gynecologic practice. The incidence is estimated to be about 20–25% worldwide1. Most uterine fibroids are asymptomatic but sometimes cause abnormal uterine bleeding, pelvic pressure, pelvic pain, and adverse reproductive outcomes, thus diminishing the quality of life of women2,3. Management of fibroids depends on individual situations and includes options such as surgery, medication, and revisit observation4. A hysterectomy is an important method to treat uterine fibroids and is a radical surger....

IRCP was performed on 41 patients with uterine fibroids and traditional LM was performed on 72 patients from 2013 to 2016. 9 cases (12.5%) in the LM group were converted to laparotomy because of massive bleeding, difficulty in enucleation, or suturing, while laparoscopy was performed successfully in all cases in the IRCP group. The percentage of conversion to laparotomy was significantly higher in the LM group (p = 0.025). Excluding the 9 cases converted to laparotomy, the average age of .......

Uterine fibroids are the most common benign tumors of the female reproductive system, affecting 20–25% of all women1 and causing abnormal uterine bleeding, recurrent miscarriage, pelvic pain, premature birth, and infertility in 10–30% cases2. As most patients with uterine fibroids are asymptomatic, the actual incidence may be higher than recognized1. Management of uterine fibroids are generally based on various factors including the age a.......
