Consensus statement for the management
of chronic pelvic pain and endometriosis:
proceedings of an expert-panel consensus
process

Joseph C. Gambone, D.O., M.P.H.,a,b Brian S. Mittman, Ph.D.,b,cMalcolm G. Munro, M.D.,a Anthony R. Scialli, M.D.,d Craig A. Winkel, M.D., M.B.A.,dand the Chronic Pelvic Pain/Endometriosis Working Group UCLA Medical School, Los Angeles, California Objective: To develop recommendations for the medical and surgical care of women who present with
chronic pelvic pain (CPP) and are likely to have endometriosis as the underlying cause.
Design: An expert panel comprised of practicing gynecologists from throughout the United States and experts
in consensus guideline development was convened. After completion of a structured literature search and
creation of draft algorithms by an executive committee, the expert panel of Ͼ50 practicing gynecologists met
for a 2-day consensus conference during which the clinical recommendations and algorithms were reviewed,
refined, and then ratified by unanimous or near-unanimous votes.
Patient(s): Women presenting with CPP who are likely to have endometriosis as the underlying cause.
Main Outcome Measure(s): None.
Conclusion(s): Chronic pelvic pain frequently occurs secondary to nongynecologic conditions that must be
considered in the evaluation of affected women. For women in whom endometriosis is the suspected cause of
the pain, laparoscopic confirmation of the diagnosis is unnecessary, and a trial of medical therapy, including
second-line therapies such as danazol, GnRH agonists, and progestins, is justified provided that there are no other indications for surgery such as the presence of a suspicious adnexal mass. When surgery is necessary, laparoscopic approaches seem to offer comparable clinical outcomes to those performed via laparotomy, but with reduced morbidity. The balance of evidence supports the use of adjuvant postoperative medical therapy after conservative surgery for CPP. There is some evidence that adjuvant presacral neurectomy adds benefit for midline pain, but currently, there is inadequate evidence to support the use of uterosacral nerve ablation or uterine suspension. Hysterectomy alone has undocumented value in the surgical management of women with endometriosis-associated CPP.

If one or more findings are con-sistent with a condition other than endometriosis withoutadnexal mass, then further diagnostic testing and/or treat-ment should be conducted, as appropriate (see section B ofthe algorithm).
