Background
Surgical site infection (SSI) is one of the major complications after appendectomy. Among the many efforts to reduce variable risk factors, subcutaneous wound irrigation has been reported in some abdominal surgeries. However, there are no relevant literatures regarding patients who underwent laparoscopic appendectomy. This study aimed to determine the effect of wound irrigation before skin closure when performing laparoscopic appendectomy.
Methods
We included patients who had undergone laparoscopic appendectomy due to acute appendicitis from March 2017 to October 2019 from three hospitals. Clinical data of 333 patients were retrospectively collected, and we divided 333 patients into three groups according to the method of wound irrigation: no irrigation (n = 93), saline irrigation (n = 144), and povidone-iodine (PI) (n = 96) groups.
Results
A total of 15 patients (4.5%) were diagnosed with SSI within postoperative 30 days. There was no difference in the SSI rates (4.3% vs. 5.1% vs. 4.5%, p = 0.953). None of the factors were associated with SSI among the variables (sex, age, ASA, perforated appendicitis, preoperative WBC and hemoglobin levels, operation time, wound irrigation, type of wound closure material, and preoperative and postoperative fever).
Conclusions
Wound irrigation did not affect the SSI rate in patients who underwent laparoscopic appendectomy.
