Endosalpingiosis in laparoscopy

Study Objective. To estimate the laparoscopic frequency of endosalpingiosis Versus other causes of peritoneal proliferation. Design. Clinic-based, prospective, nonrandomized study (Canadian Task Force classification II-2). Setting. University-affiliated hospital. Patients. The 1107 consecutive women undergoing laparoscopy over 1 year. intervention. Peritoneoscopy was performed during laparoscopy. All peritoneal proliferations were excised and examined by histology. Measurements and Main Results. In 7.6% of patients there was histologic evidence of endosalpingiosis. The frequency in asymptomatic women undergoing elective sterilization was 8.3%, and in infertile patients it was not significantly higher (11.7%, p = 0.6765). No significant difference was seen between patients with (7.3%) and without (7.3%) lower abdominal pain (p = 0.7027). Conclusion. Endosalpingiosis is the second most common cause of peritoneal proliferation in the lower abdomen, with histologic evidence of the disorder in more than 7% of premenopausal women. In contrast to endometriosis, endosalpingiosis plays only a minor role in the evaluation of infertility and lower abdominal pain. Because of its relationship to serous ovarian neoplasms of low malignant potential, further prospective studies are urgently needed.
