    OBJECTIVES: Cervical cancer is one of the most frequently diagnosed cancers in pregnancy. Our aim was to evaluate the safety and efficacy of abdominal radical trachelectomy (ART) for pregnant women with early-stage cervical cancer who strongly desire to preserve their pregnancies. METHODS/MATERIALS: A retrospective observational study was performed for stage IB1 cervical cancer patients who underwent ART or radical hysterectomy (RH) at our hospital between February 2013 and June 2017. We compared differences in perioperative findings and oncologic outcomes among ART during pregnancy (ART-DP), ART, and RH groups. RESULTS: A total of 38 patients were included in this analysis. Six, 10, and 22 patients were assigned to the ART-DP, ART, and RH groups, respectively. There were no significant differences in the distribution of pathological TNM classifications, histology, tumor size, stromal invasion, and lymph-vascular space invasion among the 3 groups. The patients in the ART-DP group were younger than those in the RH group (P = 0.014). The ART-DP group was associated with more blood loss and prolonged surgery compared with the RH group (P = 0.017 and P = 0.014). The number of total lymph nodes in the ART-DP group was lower than that in the RH group (P = 0.036). However, there were no significant differences in age, surgical time, blood loss, or lymph node count between the ART-DP and ART groups. There were no significant differences in progression-free and overall survival times among the 3 groups, and no recurrence was observed in the ART-DP group. CONCLUSIONS: Abdominal radical trachelectomy may be a tolerable treatment option for pregnant women with early-stage cervical cancer who strongly desire a baby.

    Uterine sacculation is rare complication affecting the pregnant uterus, and is difficult to diagnose. Sacculation consists of a transitory pouch or sac-like structure caused by inverted uterine polarity. Vaginal delivery is difficult, and even cesarean section can be difficult because of peculiar risks associated with uterine sacculation. We report a pregnant patient with posterior sacculation due to a huge myoma in the lower anterior uterine segment. Sacculation, especially that complicated by a huge myoma, is very difficult to accurately diagnose and makes cesarean section surgery challenging. Because of the myoma in our present case, opening the lower uterine segment was impossible with cesarean section. The uterus was instead opened by corporeal vertical cesarean section. Myomectomy was not performed and the giant myoma thus remained. Postoperative assessment revealed the uterus to still be retroverted. The giant myoma was the cause of sacculation in this case.
