When is Endometriosis Surgery an Emergency?

When is Endometriosis Surgery an Emergency?

Endometriosis is a chronic estrogen-dependent disease which is defined as the localization of endometrial glandular and stromal cells outside the uterine cavity. Lifelong management should be planned with the goal of maximizing the use of medical treatment and avoiding repeated surgical procedures. Therapies for endometriosis-related symptoms including dysmenorrhea, dyspareunia, chronic pelvic pain, and infertility are mainly analgesics, hormonal treatments, surgical intervention, and a combined approach. Due to complications and disadvantages of surgery such as risk of organ damage (especially the bowel, bladder, ureters, blood vessels), possible reduction of ovarian reserve (eg, after ovarian cyst excision), adhesion formation, possible lack of improvements in pain or recurrence of disease/pain, necessity for the use of postoperative medical treatment to decrease recurrence and standard surgical risks, surgical management is rarely preferred in clinical practice (1). However, non-surgical management of ovarian endometrioma may have some potential drawbacks and risks such as causing pelvic inflammatory disease or Tubo-ovarian abscesses through rupture or infection, the risk of malignant transformation later in life, and the negative impact of ovarian endometrioma on the ovarian reserve (2). Furthermore, surgical intervention has some advantages over medical treatments that provide a histologic diagnosis, allows assessment of pelvic cysts or masses with features concerning for malignancy, and reduces pain by destroying all endometriotic implants (3). There are also some cases that surgical intervention should be preferred.

They are as follows:

  • Need for tissue diagnosis of endometriosis,
  • Contraindications to or refusal of medical therapy,
  • Persistent pain despite medical therapy,
  • Obstruction of the bowel or urinary tract,
  • Management of endometrioma rupture,
  • Exclusion of malignancy especially in endometriomas having a typical appearance and growing fast.

Prior to ascribing a patient's abdominal or pelvic pain to endometriosis, the clinician should consider other important causes of such pain, including ectopic pregnancy, pelvic infection, and ovarian torsion. Patients may also have concomitant endometriosis and inflammatory bowel disease (stricturing Crohn disease). Endometriosis may be a cause for acute abdomen in women, and it should be considered in the differential diagnosis (4). The first stage to be done in such emergency cases is taking a careful anamnesis and performing a detailed physical and pelvic examination. Then hemogram and a pregnancy test should be ordered to differentiate the presence of pregnancy and pregnancy-related adverse conditions. Imaging modalities such as ultrasonography, Doppler ultrasonography, and magnetic resonance imaging can be used in differential diagnosis. Other departments such as General surgery and Urology should be consulted to rule out the presence of an emergency related to the environmental organs including appendicitis, nephrolithiasis or acute pyelonephritis.

Especially in the case of endometrioma rupture, early surgical intervention should be performed to reduce the dissemination of endometriotic cyst fluid spread, prevent adhesions and preserve future fertility (5). If obstruction of the bowel or urinary tract occurs due to infiltration of endometriosis, urgent surgical management plays a vital role to minimalize the loss of organ function.

Although blood tests such as serum CA125 level are not sensitive and specific for endometriosis, increased blood values of these markers during follow-up, changes in the ultrasonographic appearance of endometriomas, and aggravation of patient symptoms may also require emergent surgical intervention to rule out endometriosis-associated malignant transformation or any other morbid conditions.

Deep infiltrating endometriosis is the most severe manifestation of endometriosis, affecting 20% of patients with endometriosis. It is defined as the infiltration of ectopic endometrial tissue under the peritoneum, pelvic structures, and the organ walls such as the uterosacral ligaments, colon, vagina, bladder, ureter, rectovaginal septum, and the lateral parametrium. Lateral parametrium covers the retroperitoneal connective tissue from the uterus to the lateral pelvic wall. If endometriosis spread to the parametrium, surgical intervention plays a major role in management (6). However, preoperative clinical treatment can be applied for the reduction of tissue injury and less aggressive surgical intervention (7). While disc excision is performed for single lesions, segmental resection is preferred for larger lesions or when neoplasia is a concern (8).
Surgical resection can be conservative (treatment of endometriosis by ablation or resection) or definitive (removal of all visible implants). The main objective should be therapeutic and effective surgical intervention. The potential benefits and complications should be discussed with the patient based on her age, obstetric history, desire for pregnancy, and symptoms, the characteristics, and localization of the endometriotic lesions (9). Ablation is aimed to completely destroy endometrial epithelium surrounded by stroma. Excisional surgery results in a more favorable outcome than drainage and ablation regarding the recurrence of disease and symptoms, and obstetric outcomes. Ovarian cystectomy using stripping technique or combined excision/ablation technique is the preferred surgical technique comparing with ablation in terms of endometrioma recurrence, pain symptoms and increased spontaneous conception rate among subfertile patients (10). In the case of ovarian torsion due to the presence of endometrioma, detorsion of the ovary and cystectomy of the endometrioma is the most appropriate approach. Clinicians can consider hysterectomy with oophorectomy and removal of all visible endometriosis lesions in women who do not have fertility desires and have no response to other conservative therapies. It should be shared with the patient that hysterectomy is not a definitive treatment for endometriosis. Laparotomy and laparoscopy are equally effective in the treatment of endometriosis, but laparoscopic surgery appears to be superior to laparotomy due to less postoperative pain, shorter hospital stay, and quicker recovery and better cosmetic outcome (11*). In the case of emergent surgery for endometriosis, if the vital signs of the patient is stable, laparoscopy may be preferable. Postoperative use of hormonal therapy is recommended in patients who do not desire to become pregnant immediately after surgery (12).

Despite extensive research, the optimal management of endometriosis still remains unclear. The decision for treatment should be patient-centered considering her clinical presentation and age, symptom severity, disease extent and location, reproductive desires, other comorbidities, side effects and complications related with medical treatment and surgery, and cost (13). Relief of pain, amelioration of infertility, prevention of progression of the disease, restoration of normal anatomy, and delay of recurrence should be aimed in the management of endometriosis, even in emergency situations (14).

As a result, all women with endometriosis should be evaluated with a multidisciplinary approach considering all possibilities in differential diagnosis (15). The final decision for treatment of urgent cases should be made in a short time based on tolerability, therapeutic effectiveness, the physician’s experience, the patient’s preferences, and needs, cost.

    Like so many women who have tirelessly sought a correct diagnosis and proper, thorough medical treatment for endometriosis, I found myself 26 years into this unwanted journey without clear answers or help from four previous gynecological doctors and two emergency laparoscopic surgeries. I desperately wanted to avoid the ER again; a CT scan for appendicitis also revealed a likely endometrioma…
