Single-Incision Retroperitoneal Laparoscopic Resection of Adrenal Tumors in Children

We describe our experience with single-incision retroperitoneal laparoscopic (SIRL) for resection of adrenal tumors in pediatric patients and discuss the technique's clinical value.

We retrospectively analyzed clinical data of 27 pediatric patients who underwent SIRL between January 2020 and September 2023. Patients with tumors >5 cm in size and those requiring vascular skeletonization surgery or extensive lymph node dissection were excluded. Demographic, perioperative, and prognostic data were collected, and computed tomography (CT) and magnetic resonance imaging were used for preoperative tumor assessment.

Of 27 patients, 16 were male and 11 were female; mean age 54 ± 45 months and mean body mass index 17.2 ± 3.6 kg/m². Mean tumor length, width, and height were 4.1 ± 1.8 cm, 3.3 ± 2.1 cm, and 2.9 ± 1.7 cm, respectively. One patient experienced a diaphragmatic tear, three patients incurred peritoneal damage, and one patient developed postoperative renal artery injury, leading to thrombosis and renal atrophy. No surgery was converted to open surgery, and no intraoperative or postoperative blood transfusions were required. Operative time, blood loss, and postoperative dietary recovery time were satisfactory. No local recurrence or distant metastases were detected during the 6-48 months of follow-up involving outpatient and telephone assessments.

Application of SIRL in pediatric patients with adrenal tumors achieved favorable clinical outcomes with an effective, minimally invasive surgical option for treating children with adrenal tumors. This technique demands a high level of surgical expertise, specialized instruments and experienced surgeons. Our findings indicate that SIRL is safe and provides significant postoperative benefits in pediatric patients.
