Radical trachelectomy is considered in patients with early-stage cervical cancer who desire future fertility. This article is accompanied by a video that provides step-by-step demonstration of a uterine artery-sparing robotic-assisted radical trachelectomy in a patient with stage IB1 squamous cell carcinoma of the cervix, a 2-cm mass, and a desire for future fertility. We also conducted a review of the literature examining the use of uterine artery-sparing techniques among minimally invasive radical trachelectomies. Using PubMed, Google Scholar, and Ovid search tools, 28 total publications were reviewed, of which 16 were eligible for use in our comparison. With the addition of our case report, a total of 154 cases sparing the uterine artery and 40 cases sacrificing the uterine artery were examined, including both conventional laparoscopic and robotic-assisted approaches. Data describing patient demographics as well as surgical, oncologic, and fertility outcomes were collected. The mean age was 30 years for the spared group and 32 years for the sacrificed group. At least 42% of the women in the spared and 53% of the uterine artery-sacrificed group were nulliparous. The majority of cases in both the spared and sacrificed groups represented squamous cell histology (71% for spared and 51% for sacrificed) followed by adenocarcinoma (24% vs 43%). The majority of the patients in both groups had stage IB1 disease (79% for spared vs 65% for sacrificed). The operative times among the 2 groups were similar, with a mean time of 314 minutes (range, 170-420 minutes) in the spared group and 283 minutes (range, 172-345 minutes) in the sacrificed group. The mean estimated blood loss was 173 mL (range, 23-300 mL) in the spared group and 77 mL (range, 50-250 mL) in the sacrificed group. The recurrence rates for the uterine artery-sparing and -sacrificing groups were equal at 2.6% after a mean follow-up of 42 months and 26 months, respectively. The methods of reporting fertility outcomes were varied among the different publications, with 41 patients achieving pregnancy in the spared group and 2 patients achieving pregnancy in the sacrificed group. Among patients who were not trying to conceive or had not conceived, 15 patients in the spared group and 6 patients in the sacrificed group were reported to have normal menses. The successful preservation of uterine arteries supports the maintenance of uterine arterial blood flow and is used by many gynecologic surgeons performing minimally invasive radical trachelectomy, with promising oncologic and obstetric outcomes.
