Episiotomy is a common procedure worldwide; however, its value in prevention of various maternal and neonatal complications remains unproven. One of the common assumptions is that suturing of episiotomy, a straight incision which length and depth are determined by the obstetrician, might be easier compared to repair of unpredictable spontaneous perineal tears. The objective of our study was to examine this hypothesis. The data for this study was collected prospectively, as part of randomized controlled trial that examined the effects of episiotomy avoidance on advanced perineal tears in women towards their first vaginal delivery, compared to standard care. For the current analysis we compared suturing characteristics between two groups: vaginal deliveries in which episiotomy was performed, vs. deliveries with spontaneous perineal tears. Suturing characteristics included the duration of the repair, amount of suture packs and subjective rating of suturing difficulty (rated from 1 to 5). Of 525 vaginal deliveries, episiotomy was performed in 165 (31.5%) of the cases, 60 of which (36.4%) were accompanied by additional vaginal tears. Spontaneous vaginal tears without episiotomy were noted in 182 deliveries. The two groups did not differ in terms of various demographic and obstetric characteristics (age, body mass index, gestational age or birthweight); however, in the episiotomy group longer second stage and a higher percentage of vacuum extraction deliveries were noted (Table 1). No difference in the amount of suture packs or suturing difficulty was found between the two groups; however, in episiotomy group significantly higher rates of suturing duration above 10 minutes were noted (Table 1). According to our results, suturing of episiotomy is not easier, and might even be more complicated than the repair of spontaneous perineal tears. It might be related to the unpredictable nature of perineal tears, which might be shorter and shallower compared to the standard episiotomy incision.
