Efficacy and safety of an Aron Alpha method in managing giant ovarian tumors.

BACKGROUND

Giant malignant tumors have an increased risk of intraoperative rupture, which might lead to a worse disease condition and tumor recurrence. We performed a clinical study on patients with a giant ovarian mass who underwent laparoscopy combined with an Aron Alpha method.

METHODS

This retrospective clinical study spanned from January 2016 to September 2022 and included 23 patients with giant ovarian tumors treated with an Aron Alpha method.

RESULTS

The mean age of the subjects was 47.6 ± 17.8 years, mean tumor diameter 20.4 ± 5.8 cm, mean surgical duration 87.2 ± 33.1  min, and mean hemorrhage volume 94.1 ± 92.2 mL. No patient experienced intraoperative tumor rupture or surgery-related symptoms. Histopathology of excised samples revealed serous cyst adenoma and mucinous cystadenoma, mucinous cystadenoma of borderline malignancy and mature cystic teratoma, and endometriotic cyst adenoma in 6, 4, and 3 patients, respectively. The mean hospitalization period was 6.0 ± 1.2 days, and the hospitalization period was not extended in any subject.

CONCLUSION

The Aron Alpha method allows tumor resection without capsular rupture and is a useful, minimally invasive surgical method for resecting giant ovarian tumors in which malignancy cannot be ruled out.
