Advantages of Single-port Laparoscopy in the Treatment of Benign Ovarian  
Tumors in Children and Adolescents: A Multicenter Retrospective Study  
1. Starting and ending date of the project study: January 2019 to January 2023  
2. Introduction of research content:  
A multi-center analysis was performed on children and adolescents with benign ovarian 
tumors in 6 hospitals in Fujian province, and the removal of benign ovarian tumors by 
porous laparoscopy or ovarian cysts by single-pore laparoscopy was performed to 
analyze the incidence and clinical characteristics of gynecologic tumors in children and 
adolescents. The operation time, intraoperative blood loss, intraoperative tumor rupture 
rate, anal exhaust time, hospital stay, aesthetic score (CS) and visual analogue score 
(VAS) were compared between the two groups.  
3. Research objectives:   
To compare the efficacy of single-aperture laparoscopy and porous laparoscopy in 
benign ovarian tumors in Chinese children and adolescents, and to explore the most 
suitable minimally invasive surgical treatment for this special population, so as to guide 
clinical practice.  
4. Research design and methods:  
1) Data collection: Data of multicenter patients meeting the criteria were collected, 
and their general clinical data, including age, diagnosis, pathology, and ovarian tumor 
size (mean tumor diameter; In the case of bilateral ovaries, the diameter of the larger 

side was recorded), location of ovarian tumor, operation time, intraoperative blood loss, 
and intraoperative tumor rupture rate. In addition, postoperative complications, anal 
exhaust time, length of hospital stay, cosmetic score, VAS score, and 5-point Likert 
satisfaction Scale were collected.  
2) Statistical 
analysis: 
Clinical 
characteristics, 
surgery-related 
indicators, 
postoperative pain and aesthetic satisfaction of patients in the two groups were 
compared by statistical methods.  
5. Inclusion and exclusion criteria:  
Inclusion criteria: ① patients ≤18 years old; ② Postoperative pathological diagnosis 
confirmed benign ovarian tumor; ③ Multi-hole laparoscopic or single-hole 
laparoscopic surgery; ④ Medical records and pathological data were complete and 
available.  
Exclusion criteria: ① Patients with malignant pathological diagnosis; ② Patients 
undergoing open surgery; ③ Incomplete medical records or pathological data.  
6. Protection measures for subjects:   
The medical records used in this study were obtained from previous clinical diagnosis 
and treatment, and the postoperative satisfaction of patients was interviewed by 
telephone. The researchers would inform the information orally and obtain the consent 
of patients and their families before the study. By controlling the risk of disclosure of 
personal privacy through anonymization and other means, the subject will not accept 
any additional medical intervention/examination, will not increase the risk of routine 

diagnosis and treatment, will not affect his access to normal medical services, and the 
risk to the subject is less than the minimum risk. Any public reporting of the results of 
this study will not identify the individual patients. We will make every effort to protect 
the privacy of our patients' personal medical information to the extent permitted by law.
