Background: Acute appendicitis is the most common emergency surgical condition in the world, in which appendectomy is the standard treatment. In complicated appendicitis after an appendectomy, the method of wound closure has played a major role in surgical site infection. The study aimed to compare the delayed primary closure versus primary closure in patients with complicated appendicitis underwent emergency open appendectomy. Material and Methods: A total of 50 patients with complicated appendicitis (gangrenous, abscess, perforated appendicitis with pyoperitoneum) admitted in the surgical ward from October 2018 to September 2019 were included in this study. After open appendectomy the patients were randomly assigned into two groups of Delayed primary closure and primary closure after written and informed consent. All the patients were examined for signs and symptoms of surgical site infection periodically in ward and outpatient on weakly basis for one month and recorded the outcome of wound infection. Results: out of 50 patients, In DPC there was 2 patients with positive signs of infection but in PC there were 7 patients with infection. The length of stay in DPC (7.22±2.8) and PC (7.24±3.27) with no significant difference between the two groups. Conclusion: In our study, patients with complicated appendicitis underwent emergency open appendectomy, DPC may be the preferable method than PC because of the lower incidence of SSI and related complications.
