Brief Summary

Chronic pelvic pain (CPP) is a common disease with multiple systems and multiple causes. In recent years, the incidence rate of CPP in women has gradually increased. It is a pain symptom that originates from pelvic organs or related structures and lasts for more than 6 months. It is closely related to gynecological diseases such as endometriosis (EMs), adenomyosis, pelvic inflammatory disease (PID), uterine leiomyoma, residual ovarian syndrome, pelvic venous congestion syndrome (PCS), etc. But its pathophysiology is very complex and still needs further exploration. Recent studies have shown that central sensitization is an important mechanism for the sustained existence of CPP. Explore the relationship between chronic pelvic pain and its postoperative outcomes, as well as preoperative endometriosis related questionnaire surveys such as such as Endometriosis Health Profile-30 (EHP-30), Central Sensitivity Inventory (CSI), Simplified McGill Pain Questionnaire (SF-MPQ). Explore the relationship between chronic pelvic pain and its postoperative outcomes, as well as in vitro detection results such as preoperative venous blood, intraoperative pathological tissue immunohistochemistry, ELISA, transcriptome sequencing in patients with endometriosis.

Outcome Measures

Primary Outcomes (2)

  • Chronic pelvic pain

    Using Simplified McGill Pain Questionnaire (SF-MPQ) for scoring

    Within 3 days before surgery, before leaving the hospital after surgery, postoperative discharge (6 months -3 years)

  • In vitro detection results

    The results of immunohistochemistry, ELISA, and transcriptome sequencing of preoperative venous blood and endometrial tissue excised during surgery in patients with endometriosis

    Venous blood within 3 days before surgery; Endometriosis sample excised during surgery
