Introduction of Intracapsular Rotary-cut Procedures (IRCP): A Modified Hysteromyomectomy Procedures Facilitating Fertility Preservation.

Abstract

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.
