The Efficacy of Laparoscopic Surgical Treatment of Ovarian Remnant and Ovarian Retention Syndromes

Abstract

Study ObjectiveTo evaluate the degree of pain relief provided by laparoscopic surgical treatment of ovarian remnant and ovarian retention syndromes. DesignRetrospective analysis (Canadian Task Force classification II-2). SettingAcademic hospital and affiliated outpatient offices. PatientsA total of 54 patients from 2004 to 2008 who underwent surgical treatment for suspected ovarian remnant syndrome or ovarian retention syndrome. InterventionsOophorectomy. Measurements and Main ResultsPreoperative and postoperative pain scores were recorded from patients who underwent surgical treatment for either ovarian remnant or ovarian retention syndrome. Data regarding comorbid diagnoses that would contribute to chronic abdominopelvic pain, previous surgical history, surgical complications, and pathology to confirm the preoperative diagnosis were also collected. Pathology confirmed that ovarian tissue was removed in 52 of the 54 patients. Forty percent and 41% of patients with ovarian remnant and ovarian retention, respectively, achieved a 50% reduction of their average pain levels; 50% and 56%, respectively, achieved a 30% reduction in average pain levels. There was not a statistically significant difference in postoperative pain relief between the 2 groups. Cases with ovarian remnant syndrome had more prior surgical procedures (4.8 vs 3.6, p = .049) and were more likely to have a surgical complication (25% vs 3%, p = .03) than cases with ovarian retention syndrome. Patients with a 30% or greater decrease in their pain levels postoperatively were likely to have fewer other diagnoses associated with chronic pain (1.4 ± 1.1 vs 2.1 ± 0.9, p = .009). ConclusionSurgical treatment for ovarian remnant or ovarian retention syndrome is effective but is most effective in patients with no other pain-related diagnoses. Thus, it is important to thoroughly evaluate women with ovarian remnant or ovarian retention syndrome for other pelvic pain–related disorders. In almost all cases, surgery can be done laparoscopically in patients with these syndromes.
