The clinical manifestations of acute pelvic inflammatory disease can vary depending on the severity and extent of the inflammation. Pelvic inflammatory disease is a general term for inflammation of the female internal genitalia (uterine body, fallopian tubes, ovaries) and surrounding connective tissue, pelvic peritoneum, which can be confined to one site or occur in several sites at the same time. Most patients with acute pelvic inflammatory disease have an acute onset, with pain in the lower abdomen accompanied by fever and, if severe, high fever, chills, headache and lack of appetite. If there is peritonitis, there are digestive symptoms such as nausea, vomiting, abdominal distention, diarrhea, etc. In case of abscess formation, there are symptoms of lower abdominal mass and local pressure irritation, such as bladder irritation (difficult urination, frequent urination, painful urination, etc.), rectal irritation (diarrhea, urgency and difficulty in defecation). On examination, the patient has an acute appearance with high body temperature, rapid heart rate, abdominal distension, lower abdominal muscle tension, pressure pain and rebound pain, and diminished or absent bowel sounds. On pelvic examination, there is vaginal congestion, increased discharge, fornix tenderness, cervical congestion, marked lifting pain, and uterine body tenderness. On examination of the pelvic area, the vagina is congested with increased blood and discharge, the fornix is painful to palpation, the cervix is congested with painful lifting, and the body of the uterus is painful to palpation. Acute pelvic inflammatory disease has a rapid onset and should be seen by a local hospital in a timely manner if the condition is severe.
