Chronic pelvic pain and the role of exploratory laparoscopy as diagnostic and therapeutic tool: a retrospective observational study

Background:
Forty percent of exploratory laparoscopies are performed for chronic pelvic pain (CPP). However, a
final diagnosis is still unreported in 35% of the patients. We decided to evaluate the identification of pathological lesions and the improvement of painful symptoms in patients with CPP and normal physical examination and imaging and who are scheduled for exploratory laparoscopy. The prospective study was designed in a tertiary referral center for endometriosis. Forty-eight patients complaining of CPP and scheduled for exploratory laparoscopy were included. Pelvic pain intensity was assessed using the visual analogue pain scale (VAS), and at inclusion, negative clinical and imaging assessments were required. During exploratory laparoscopy, the recognized lesions were reported and different surgical treatment options were performed depending on the location of the
lesion.
Results:
In 98% of the cases, exploratory laparoscopy demonstrated the presence of pelvic anomalies that had not been diagnosed at the time of clinical and imaging examination. After surgery, a significant improvement of CPP has been demonstrated in 24 (59%) patients with VAS < 5 postoperatively.
Conclusions:
Exploratory laparoscopy is reasonable in patients complaining of CPP, allowing a final diagnosis in a
high percentage of patients and a significant improvement in pain symptom in 59% of the cases. This study was retrospectively registered by our local Ethics Committee on February 7, 2018 (B412201835729).
