Assessment of local wound healing complications after groin surgery: a comparative study between two wound closure techniques

Abstract

Background: Scars are inevitable sequelae of any surgical procedure. Wound closure method has been shown to affect the post-operative scar outcome. This study compared the post-operative scar of two wound closure techniques in paediatric groin surgeries. Methods: This was a prospective comparative analytical study involving 60 paediatric surgical patients randomized into two groups. After a groin procedure in patients who met the inclusion criteria, patients in Group A had only the skin layer closed whereas both skin and subcutaneous tissue were closed in Group B. Scar assessment was done using the Patient and Observer Scar Assessment Scale (POSAS) at 1 week, 3 weeks and 6 weeks after surgery. Results: The mean POSAS score was 108.44 ± 20.32 and 113.91 ± 26.18 for groups A & B respectively (P = 0.379) while the overall opinion score for groups A & B were 19 (IQR = 4) and 21(IQR = 10) (P = 0.392) respectively. The average duration of surgery was 35 minutes in each group. There was equal distribution of seroma formation among the two wound closure groups. Among the patients that developed wound dehiscence, 25% were in group A, while 75% were in group B. Ninety-five percent of the wounds healed with fine linear scar. Conclusion: Majority of paediatric groin wounds heal with fine linear scars. Although no statistically significant association exists between wound closure technique and scar assessment scores, patients who had two-layer wound closure recorded worse scar assessment scores compared to those who had one-layer closure.
