Can sterile and non-sterile surgeries be performed together?

Patient's question:

Gender: Female
Age: 42
My friend had an appendectomy and a right salpingo-oophorectomy due to purulent tubo-ovarian abscess and acute exacerbation of chronic appendicitis. I often hear people say that appendicitis can only be performed as an emergency surgery and cannot be done together with clean surgery. Is that true? Why?

Doctor's answer:

According to your description, purulent tubo-ovarian abscess and acute exacerbation of chronic appendicitis are both classified as sterile surgeries and can be performed simultaneously. The occurrence of ovarianitis not only affects women's lives but also leads to gynecological diseases. Therefore, it is best to have a vaginal discharge test at the gynecology department of the hospital, identify the cause, and then receive symptomatic treatment. In daily life, you should drink more water and pay attention to personal hygiene.
