Input: We found one RCT, which included 13 women, that met our inclusion criteria and this trial reported data on LARVH versus RAH. Women who underwent LARVH for treatment of early-stage cervical cancer appeared to have less blood loss compared with those who underwent RAH. The trial reported a borderline significant difference between the two types of surgery (median blood loss 400 mL (interquartile range (IQR): 325 to 1050) and 1000 mL (IQR: 800 to 1025) for LARVH and RAH, respectively, P value = 0.05). RAH was associated with significantly shorter operation time compared with LARVH (median: 180 minutes with LARVH versus 138 minutes with RAH, P value = 0.05). There was no statistically significant difference in the risk of perioperative complications in women who underwent LARVH and RAH. The trial reported two (29%) and four (57%) cases of intraoperative and postoperative complications, respectively, in the LARVH group and no (0%) reported cases of intraoperative complications and five (83%) cases of postoperative complications in the RAH group. There were no reported cases of severe perioperative complications. Bladder and bowel dysfunction of either a transient or chronic nature remain major morbidities after radical hysterectomy, and the one included study showed that there may be significantly less after LARVH. The included trial lacked statistical power due to the small number of women in each group and the low number of observed events. Therefore, the absence of reliable evidence, regarding the effectiveness and safety of the two surgical techniques for the management of early-stage cervical cancer, precludes any definitive guidance or recommendations for clinical practice. The trial did not report data on long-term outcomes, but was at moderate risk of bias due to very low numbers of included women.
Output:

We carried out a systematic review and searched for published and unpublished randomised controlled trials (RCTs) that compared open and laparoscopically assisted vaginal methods of performing radical hysterectomy in women with early cervical cancer. The evidence is current to July 2013. We found only one relevant trial. It included only 13 women; seven had a laparoscopically assisted radical vaginal hysterectomy (LARVH) and six had radical abdominal hysterectomy (RAH). Women who underwent LARVH appeared to have less blood loss, shorter hospital stay and less requirement for pain medication compared with those who underwent RAH. There was no statistically significant difference in the risk of complications related to the operation in women who underwent LARVH and RAH. However, RAH had a significantly shorter operation time compared with LARVH. The trial did not assess overall survival and progression-free survival (PFS; the time that a woman lives with the cancer but does not get worse) or quality of life (QoL) as the main focus of the trial was to examine short-term complications. Due to the small number of cases and the short-term scope of the trial, we were unable to reach any definite conclusions about the relative benefits and harms of the two forms of treatment and we were unable to identify subgroups of women who are likely to benefit from one treatment or the other.
