Objective To investigate the feasibility and safety of robot-assisted laparoscopic surgery for retroperitoneal tumors (RT) in children. Methods A retrospective analysis was carried out on the clinical data of 12 RT children who underwent robot-assisted laparoscopic surgery in the department of pediatric surgery of the First Affiliated Hospital of Guangxi Medical University from April 2017 to April 2024. Preoperatively, all children underwent abdominal color ultrasound, CT and other examinations to clarify the location of the tumor and its adjacency with the surrounding tissues. Among them, there were 6 boys and 6 girls; the age (in months) ranged from 2 months to 14 years, with a median age of 8.5 years; the weight range was 5.4 to 47.0 kg, with a median weight of 25.5 kg; the tumor diameter range was 2.5 to 14.0 cm, with a median tumor diameter of 4.2 cm. The operation time, intraoperative blood loss, treatment outcomes, and other relevant data of the 12 children were collected for analysis. Results All 12 cases of roboti-assisted laparoscopic retroperitoneal tumor resection (RRTR) were successfully completed without converted surgery. The operation time was 132-305 (195.5±43.92) min, the intraoperative blood loss range was 0 to 100 mL, with a median of 20 mL, and no cases required intraoperative or postoperative blood transfusion. The postoperative feeding time range was 1 to 5 days, with a median of 2 days. The frequency range of postoperative use of analgesic drugs was 0 to 7 times, with a median of 1 time. The postoperative hospital stay was 4-14 (7.17±1.75) d. Four cases (33.33%) with malignant tumors underwent simultaneous peritumoral lymph node dissection, and postoperative pathological examination showed negative tumor margins in all cases. One case (8.3%) of the children presented with postoperative chylous leakage in the abdominal cavity and was conservatively cured and discharged. The postoperative follow-up period was 8-48 (17.00±8.33) months, with no tumor recurrence or reoperation cases. Conclusion RRTR is safe and feasible for the treatment of pediatric RT, particularly demonstrating significant advantages in meticulous anatomical dissection and enhanced recovery after surgery, providing a new option for the surgical treatment of pediatric RT.
