Endoscopic Surgical Approach for Pediatric Solid Tumors That Permits Complete Curability and Exhibits Cosmetic...

We actively use novel endoscopic surgical approaches with complete curability and good cosmetic outcomes to facilitate the removal of resected tumors from the body via a small incision. This retrospective study reviewed the medical records of patients who underwent endoscopic surgery for treating solid tumors in the abdominal, thoracic, and urogenital regions between April 2013 and March 2020. At our institution, minimally invasive surgery (MIS) is performed for malignant tumors with a maximum diameter of ≤5 cm and nonmalignant tumors without diameter restrictions, although both need to have no vascular encasement. In total, 135 pediatric solid tumor resections were performed at our institution during the aforementioned period, among whom 37 patients satisfied the MIS criteria. Among them, 28 patients underwent endoscopic surgeries, whereas 9 underwent open surgeries. The median surgical durations were 192 and 138 minutes in the MIS and open groups, respectively (P = .096). The median volume of blood loss was 1 and 8 mL in the MIS and open groups, respectively (P = .086). The median lengths of hospital stay were 8 and 7 days in the MIS and open groups, respectively (P = .178). One patient in each group had Clavien-Dindo grade ≥Ⅲ complications. However, there was no surgery-related death. All patients receiving MIS had satisfactory operative scarring, early recovery, and good cosmetic outcomes. MIS can be used for pediatric solid tumors, considering the patient's quality of life while allowing complete curability and providing endoscopic surgical advantages.
