Primary Versus Delayed Wound Closure in Complicated Appendectomy (The HIEDI-Yemen Trial) (HIEDI-Yemen)
A Comparative Study of Primary Versus Delayed Wound Closure Using the High-Efficiency Incision and Drainage With Irrigation (HIEDI) Technique to Minimize Surgical Site Infection (SSI) Risk in Patients Undergoing Complicated Appendectomy
The goal of this clinical trial is to compare primary wound closure (PC) versus delayed primary closure (DPC) after standardized wound decontamination using the High-Efficiency Incision and Drainage with Irrigation (HIEDI) technique in patients undergoing open appendectomy for complicated appendicitis in Sana'a, Yemen.
The main questions it aims to answer are:
- Does primary closure with HIEDI result in a non-inferior or lower incidence of Surgical Site Infection (SSI) at 30 days compared with delayed primary closure with HIEDI?
- Does primary closure with HIEDI reduce length of hospital stay and improve the trajectory of objective wound healing compared with delayed primary closure with HIEDI?
- What is the impact of each closure method on patient satisfaction and health-related quality of life?
Researchers will compare the two groups to determine the optimal, evidence-based standard of care for wound management in complicated appendicitis within a resource-limited setting.
Participants will:
- Undergo open appendectomy for intraoperatively confirmed complicated appendicitis (perforation or gangrene).
- Receive standardized HIEDI wound decontamination (meticulous debridement and pulsatile irrigation with minimum 500 mL povidone-iodine 1:10 solution).
- Be randomly allocated to either primary closure (all layers closed at surgery) or delayed primary closure (skin/subcutaneous tissue left open and closed 3-5 days later).
- Attend follow-up visits at days 7, 14, and 30 for wound assessment, infection surveillance, and outcome evaluation.

Szczegółowy opis
Complicated appendicitis (perforation or gangrene) is a significant cause of postoperative morbidity worldwide. Surgical Site Infection (SSI) is the most common complication, with reported rates exceeding 30% in low- and middle-income countries (LMICs). In Sana'a, Yemen, local data from Al-Thawra Modern General Hospital documented a 27.5% SSI rate specifically in this patient population. The optimal wound closure strategy-primary closure (PC) versus delayed primary closure (DPC)-remains debated, with previous studies yielding conflicting results largely due to lack of standardized intraoperative wound decontamination.
The High-Efficiency Incision and Drainage with Irrigation (HIEDI) technique is a standardized, aggressive decontamination protocol combining meticulous debridement of wound edges with pulsatile high-pressure irrigation using a minimum of 500 mL of povidone-iodine solution (1:10 dilution). By applying HIEDI uniformly to both study arms, this trial isolates the effect of closure timing on SSI risk.
This is a prospective, multicenter, parallel-group, 1:1 randomized controlled superiority trial with blinded outcome assessment, conducted at three tertiary care hospitals in Sana'a, Yemen. The findings will provide high-level, locally generated evidence to establish a safe, resource-conscious standard of care for Yemen and similar settings.
