A Novel Hybrid Laparoscopic–Extracorporeal Technique for Fertility-Preserving Management of Large Benign Ovarian Cysts: A Case Report

Background and Clinical Significance: The management of large benign ovarian cysts in women of reproductive age requires balancing minimally invasive surgery with oncologic safety and preservation of ovarian function. Laparoscopic cystectomy for large cysts is technically challenging and carries an increased risk of intraoperative rupture and spillage; Case Presentation: We describe a novel hybrid laparoscopic–extracorporeal technique in which controlled cyst decompression is performed using a balloon-tipped trocar through a suprapubic port under direct laparoscopic visualization. The ovary is then carefully mobilized and exteriorized through the same incision, allowing extracorporeal cystectomy and ovarian reconstruction before returning the adnexa to the abdominal cavity. This approach was applied in a series of six patients with large benign-appearing ovarian cysts, including one 42-year-old patient with an 18 cm multilocular mature cystic teratoma. There were no intraoperative or postoperative complications, no conversions to laparotomy, and all patients were discharged on postoperative day 1. Follow-up at six weeks and subsequent imaging at nine months demonstrated preserved ovarian architecture, normal menstrual function, and high patient satisfaction; Conclusions: The hybrid laparoscopic–extracorporeal approach appears feasible and may offer a safe surgical option in carefully selected patients, allowing fertility preservation while minimizing the risk of spillage. Further studies are needed to evaluate reproducibility, oncologic safety, and long-term reproductive outcomes.
