The primary aim of this study is to compare wound outcomes between two closure strategies after open appendectomy:
1. Simple interrupted skin sutures (standard method), versus
2. Subcuticular (intradermal) skin suture combined with a subcutaneous closed suction drain.
Specifically, the study aims to
* Determine whether the combined subcuticular closure with drain reduces the incidence of superficial surgical- site infection (SSI) within 30 days compared with interrupted sutures.
* Evaluate the effect of both techniques on secondary outcomes, including seroma or abscess formation, wound dehiscence, post-operative pain, cosmetic appearance of the scar, length of hospital stay, and drain-related adverse events.
