To evaluate the clinical significance and therapeutic effect of single-hole laparoscopy combined with small umbilical incision for excision of giant ovarian cysts during pregnancy.

A retrospective analysis was performed on the clinical outcomes of 6 patients undergoing single-hole laparoscopy combined with a small umbilical incision and external giant ovarian cyst (10-11 cm) pregnancy during May to Nov. 2018. data.

All 6 patients successfully completed the excision of giant ovarian cysts with single-hole laparoscopy combined with a small umbilical incision. In 6 patients, two patient′s ovarian cysts were twisted, one patient’s mesentery cysts were twisted, and other three patient′s ovaries had normal anatomical structure. No necrosis occurred, and cystectomy was performed. The median operation time was 51.50 min(43.75-63.50 min), the median intraoperative blood loss was 7.5 ml (5-20 ml), and the average hospital day was (3.50 ± 0.43) days. Follow-up, of the 6 patients, 5 were pregnant to full-term delivery (83.33%), 1 was premature (16.67%); 2 of them underwent cesarean section (33.33%), 4 were delivered in labor (66.67%); median newborn weight 3 050 g (2 750-3 162.5 g). There were no deformities and asphyxia in the newborns of 6 patients.

After sufficient pre-operative and intra-operative evaluations to rule out the possibility of severe malignant ovarian tumors and pelvic adhesions, single-hole laparoscopy combined with a small umbilical incision to remove giant ovarian cysts during pregnancy. The technique is safe and feasible and worthy of clinical promotion.
