Abstract

Objective To compare the impact of whether to apply the outer suture after inner suture on skin incision healing. Methods This study was a prospective self-controlled clinical trial. From November 2020 to September 2021, 49 patients who underwent skin resection surgery and met the inclusion criteria were admitted to Shanghai Ninth People's Hospital of Shanghai Jiao Tong University School of Medicine, including 39 females and 10 males, aged 18 to 55 years. The surgical sites included the upper limbs (17 cases), lower limbs (2 cases), shoulders (3 cases), neck (8 cases), abdomen (8 cases), chest (10 cases), and back (1 case). Each patient's surgical incision was divided equally into the outer suture segment (with inner suture and outer suture) and the outer sutureless segment (only with inner suture) using the random sequence method. On the day of suture removal and at the 1^st month of follow-up after surgery, the incision dehiscence was observed. At the 12^th month of follow-up after surgery, the scar hyperplasia was observed and the scar hyperplasia rate was calculated. At the 6^th and 12^th months of follow-up after surgery, the scar width of incision was measured. At the 1^st, 6^th, and 12^th months of follow-up after surgery, the Vancouver Scar Scale (VSS) was used to assess scar condition of the incision in terms of color, thickness, vascularization, and pliability, and the total score was calculated. The number of patients corresponding to the VSS score in the 1^stand 12^th months of follow-up after surgery was 41 and 46, respectively, while the number of patients corresponding to other indicators was 49. Results On the day of suture removal and at the 1^st month of follow-up after surgery, no dehiscence was observed in either the outer suture segment or outer sutureless segment of any patient's surgical incision. At the 12^th month of follow-up after surgery, the scar hyperplasia rate in the outer suture segment was 2.04% (1/49), which was not significantly different from 4.08% (2/49) in the outer sutureless segment (P>0.05). At the 6^th and 12^th months of follow-up after surgery, the scar widths in the outer sutureless segment of incision were 1.48 (1.01, 1.91) and 1.41 (1.13, 1.93) mm, respectively, which were not significantly different from 1.38 (1.00, 1.94) mm and 1.45 (1.17, 1.84) mm in the outer sutureless segment (P>0.05). At the 1^st, 6^th, and 12^th months of follow-up after surgery, there were no statistically significant differences either in scores of scar color, thickness, vascularization, pliability, or in the total score of scar of the incision between the outer suture segment and the outer sutureless segment (P>0.05). Conclusions After tension reduction and fine inner suture of skin incisions, outer suture has no significant effect on incision healing or postoperative scar appearance.
