INTRODUCTION: Hysteroscopic septoplasty is a safe and routinely used procedure for the treatment of septate uterus. The aim of this paper is to determine which hysteroscopic technique (scissors, monopolar/bipolar diathermy) is superior for post-treatment reproductive outcome.
EVIDENCE ACQUISITION: Two different hysteroscopic septoplasty instruments (scissors and monopolar/bipolar diathermy) were compared, focusing on the pregnancy outcome. In addition, all published studies and reviews regarding pregnancy outcomes that occurred after operative hysteroscopy using different techniques (bipolar, monopolar electrodes, resectoscope, VERSAPOINT™ [Ethicon LLC] and scissors) were reviewed. Dichotomous analysis, with use of the Mantel-Haenszel method, was performed for all five outcomes, with fixed effect analysis model and odds ratio (OR) as the effect measure. Analysis details included totals and subtotals with 95% confidence interval. The Multinomial CI package for the R statistical language was also used.
EVIDENCE SYNTHESIS: Out of 26 full-text articles available in the literature, two studies were finally selected as eligible, with a total number of 125 patients. Pregnancy rate for scissors was 88.8% and for resectoscope was 75.6% (OR: 2.13, I2=29%; P=0.23). Delivery rate for scissors was 78.1% and for resectoscope was 75.0% (OR: 1.29, I2=0%; P=0.53). Miscarriage rate for scissors was 21.8% and for resectoscope was 27.1% (OR: 0.78, I2=0%; P=0.53). Preterm delivery rate for scissors was 6.2% and for resectoscope was 6.7% (OR: 0.85, I2=0%; P=0.94). Term delivery rate for scissors was 71.8% and for resectoscope was 66.1% (OR: 1.32, I2=0%; P=0.47). The lack of evidence in literature regarding the potential influence in the reproductive outcome of the instrument used when performing a hysteroscopy to treat a septate uterus became radically clear.
CONCLUSIONS: No statistically significant differences were observed in reproductive outcomes between women treated for septate uterus using resectoscope or scissors.
