Objective: Paraovarian cysts have a prevalence approximately 10% that of adnexal tumors, and it is a condition frequently experienced clinically. We conducted a retrospective clinical investigation of cases operated with paraovarian cyst surgery at our hospital.
Methods: The subjects were 145 cases of paraovarian cysts operated on between May 2009 and December 2014 at our hospital. A retrospective evaluation was performed on the preoperative examinations of the paraovarian cyst cases, surgical technique, surgical observations, frequency of torsion of the pedicle, and post-operative pathological diagnosis.
Results: The mean age of the patients was 38.7 years (13–82 years, median 36 years). The preoperative diagnosis was paraovarian cyst for 53 patients (36%), ovarian cyst for 54 patients (37%), and hydrosalpinx for 3 patients (2%). A total of 35 patients were diagnosed coincidentally during surgery (24%). The surgical approach was intracorporal laparoscopy in 131 patients (90.3%). Torsion of the pedicle was observed in 10 of the 145 patients (6.9%). Torsion of the pedicle occurred in only 19 of the 1,091 cases (1.7%) of ovarian cysts (excluding endometrial cysts) that were operated on in our hospital during the same time period. The histopathological diagnosis was a benign tumor in all cases, and there were no cases of borderline malignant tumors or malignant tumors.
Conclusions: Paraovarian cysts commonly arise in patients of reproductive age. The rate of onset of torsion of the pedicle is higher than that of ovarian cysts at our hospital. When taking the preservation of fertility into consideration, this surgery may be applied to ovarian cysts, even in asymptomatic cases. The majority of cases are benign tumors, and given that it is a condition that can occur in a wide range of ages, we believe that the application of minimally invasive laparoscopic surgery is appropriate.
