Subcuticular interrupted versus continuous skin suturing in elective cesarean section in obese women: a randomized controlled trial.

To compare the interrupted subcuticular skin closure with continuous one in obese women undergoing cesarean delivery. A randomized controlled study conducted on 169 obese women with term uncomplicated singleton pregnancy who underwent elective cesarean delivery. They were randomized to either skin closure through continuous subcuticular sutures using vicryl 3/0 or interrupted subcuticular suturing using vicryl 3/0. The primary outcome parameter was occurrence of wound infection. Secondary outcomes included other skin complications, postoperative pain, operative duration and hospital stay There was a statistically higher number of cases with wound hematoma (20 vs. 10,  = .04), infection (30 vs. 15,  = .008) and those who needed reclosure of wound (8 vs. 0,  = .004) in the continuous when compared to women in the interrupted subcuticular group, respectively. Healing with secondary intension was significantly higher in women in the continuous subcuticular group (52 vs. 26, respectively,  < .001). The number of cases with wound seroma and keloid formation was not statistically different between the two groups (25 vs. 19,  = .272 and 12 vs. 5,  = .069 in the continuous vs. interrupted groups, respectively). The duration of CS was longer in those who underwent interrupted closure when compared to continuous ones. However, that was statistically insignificant (40.95 + 6.376 vs. 37.05 + 6.455,  = 0.14). Most surgical wound complications were reduced if skin closure with continuous subcuticular sutures is replaced with interrupted one.
