Summary:
Objective: The aim of this study was to analyze the incidence, causes and management in women with
chronic pelvic pain and to evaluate the role of laparoscopy.
Design: A prospective non-randomized clinical trial on 86 women with chronic pelvic pain.
Setting: Clinic of Gynecology and Obstetrics, JMF CU Martin, Slovak Republic.
Methods: A prospective clinical trial was performed on 86 patients with chronic pelvic pain, who have
undergone laparoscopy from March 2003 to March 2004. Only patients with a pain history of at least 6
month were enrolled into this trial. Specific patient’s history characteristics, laparoscopic and cytologic
findings were reviewed and analyzed (pain interval, organic findings, preoperative ultrasound examination,
previous surgical intervention, oral contraceptive usage, patient’s medical history, menstrual cycle
regularity, age, presence of dysmenorrhea). In all women, laparoscopy was performed under general
anesthesia.
Results: During the study we have performed 309 diagnostic laparoscopic examinations, from which 86
(27.8%) were done due to chronic pelvic pain. The mean patient’s age was 35.8 years (19–56). The mean
parity was 1.6, ranging from 0–5. Pelvic organ pathology was present in 88.4% of the patients. The most
frequent finding was endometriosis (31.4%). According to revised criteria of the American Fertility
Society the presence of first, second, third and fourth stage of endometriosis was 55.6, 25.9, 11.1 and
7.4%, respectively. The most frequent occurrence of endometriotic lesions were on ligamenta sacrouterina
(21.4%) and plica vesicouterina (19.0%). Pelvic adhesions, myomas, pelvic varicosities and chronic
inflammatory process were present in 25.6, 15.1, 9.3 and 3.5% of the cases, respectively. No somatic origin
of pain was identified at laparoscopy in 11.6% of patients. Preoperative ultrasonic examination with
pelvic pathology findings were performed in 36 patients, and laparoscopy correlated with ultrasonographic
findings in 31 (86.1%) cases. The average pain duration was 11.5 months (6–28) with the majority
among women with history of previous surgical intervention (48.8%) and parturated women.
Presence of pain was most common among women after 31 years of age. Predominantly, cytology examination
of biological materials (peritoneal fluid, cyst fluid) revealed an increased histiocytic reaction in
coincidence with chronic inflammation process in 31.6%.
Conclusion: Invasive laparoscopy in chronic pelvic pain pertains to one of the most important examination
procedures for its high specificity and sensitivity. Laparoscopy can reveal organic causes of pelvic
pathology in 60% of cases with the possibility of following treatment. Our combined effort should stop
the progression of such pathology leading to possible morphologic, functional and psychological alteration,
especially among young women in fertile age. Today, endometriosis still remains the main cause of
chronic pelvic pain in high percentage rate.
