title: Pregnancy-related complications after vaginal radical trachelectomy for early-stage invasive uterine cervical cancer.
abstract: BACKGROUND
  Pregnancy-related complications after vaginal radical trachelectomy (RT) for early-stage invasive uterine cervical cancer were studied in comparison with those occurring after laser conization. The strategy to reduce vaginal RT-related complications during pregnancy is also discussed.
  
  
  METHODS
  Pregnancy courses after vaginal RT in two patients and those after laser conization in five patients, whose operations were performed during the same period, were studied with respect to symptoms, cervical length, and infectious signs.
  
  
  RESULTS
  The cervix shortened progressively both in patients with laser conization and in those with RT. However, throughout the pregnancy, the remaining cervix after the operation was longer in patients who had undergone conization than in those who had undergone vaginal RT. After laser conization, two of the five patients suffered from preterm rupture of the membrane (PROM) at 36 weeks of gestation, and both patients who had undergone vaginal RT had premature PROM (pPROM), at 32 and 24 weeks of gestation, respectively.
  
  
  CONCLUSIONS
  Prevention of preterm labor and the following occurrence of pPROM is a significant task to be resolved in order to improve pregnancy outcome after vaginal RT for early-stage invasive uterine cervical cancer. Daily vaginal disinfection with povidone iodine and the administration of a ulinastatin vaginal suppository, bed rest, and the use of ritodrine would be the best approach, and a more conservative approach for stage Ia2 also might be taken into consideration.
