Objective:To evaluate prenatal and postnatal management strategies for ovarian cysts in fetuses and infants under three months of age.Methods:This retrospective analysis included 94 cases managed at Wuhan Children's Hospital, Tongji Medical College, Huazhong University of Science and Technology (December 2013 to December 2023) with prenatal/postnatal imaging, management, and outcomes data. Cysts were stratified by diameter: <3 cm ( n=44), 3-4 cm ( n=19), and ≥4 cm ( n=31). Proportions of complex cysts and ovarian necrosis rates were compared using Chi-square tests. Results:Among 94 cases , 62 were simple ovarian cysts and 32 complex (including two initially simple cysts that converted to complex in utero). Prenatal diagnosis occurred in 67 cases (52 simple, 15 complex) without intrauterine intervention and 27 were postnatally detected (10 simple, 17 complex). Ovarian necrosis affected 93.8% (30/32) of complex cysts. Both 3-4 cm and ≥4 cm groups demonstrated significantly higher complex cyst rates [12/19 and 48.3% (15/31) vs. 11.4% (5/44), χ2=15.53 and 10.92, both P<0.001] and ovarian necrosis frequencies [12/19 and 45.2% (14/31) vs. 9.1% (4/44), χ2=17.72 and 11.07, both P<0.001] compared to the <3 cm group, whereas no significant differences existed between 3-4 cm and ≥4 cm groups (both P>0.05). Conclusions:For postnatal management, surgical intervention is recommended for complex ovarian cysts in fetuses and infants within three months of age. For simple cysts ≥4 cm, surgery is advised, while those measuring 3-4 cm warrant close monitoring due to elevated necrosis risk.

Objective Summarizing the recent efficacy and initial experience of using da Vinci robot surgery for pediatric annular pancreas in our hospital.Methods The clinical data of 3 children with annular pancreas treated by Da Vinci robotic surgery in Wuhan Children's Hospital from October 2020 to December 2022 were retrospectively analyzed.Results All three cases were successfully completed with robot-assisted lateral duoduodenal anastomosis without intraoperative complications.The operation time was 240 min,212 min,135 min,respectively.Postoperative feeding was started at 12 d,7 d,and 6 d,respectively.The postoperative hospital stays were 33 d,18 d,and 13 d,respectively.The first case was complicated with neonatal necrotizing enterocolitis after operation,and was cured and discharged after conservative treatment.The remaining 2 cases were cured and discharged.The follow-up time was 2 years,3 months and 5 months,respectively.No relevant complications occurred during the follow-up period,and the prognosis of the three children was good.Conclusion Da Vinci robotic surgery is safe and feasible in the treatment of annular pancreas in children,but it still needs to be supported by large sample studies.
