Comparison of Three- and Two-Dimensional Laparoscopy in Pediatric Nissen Fundoplication.

ABSTRACT

Aim: This study aimed to evaluate the usefulness of three-dimensional (3D) versus conventional two-dimensional (2D) vision in pediatric laparoscopic Nissen fundoplication. Materials and Methods: Medical records and procedure videos of patients 18 years old or younger who underwent laparoscopic Nissen fundoplication at a single institution between January 2015 and August 2018 were retrospectively reviewed. The total pneumoperitoneum and wrapping times were measured. The number of errors during the first stitch of the wrapping was counted. Three-dimensional laparoscopy was introduced in January 2017, and data were compared between the previous 2D and current 3D groups. A questionnaire was provided to each surgeon who performed the 3D procedure. Results: Laparoscopic fundoplication was performed under 2D vision in 32 patients and under 3D vision in 19 patients. Mean ages and weights at surgery were similar between the groups. There was no significant differences in pneumoperitoneum and wrapping times between the two groups. Significantly more errors were counted in the 2D versus 3D procedure, but all patients recovered without any complications related to intraoperative errors. On the questionnaires, all 8 surgeons desired a decreased scope diameter and multidirectional visual axis. Four surgeons (50%) experienced eyestrain and 1 experienced double vision. Conclusions: This study showed no reduction in surgical time with 3D versus 2D scope use. Three-dimensional vision decreased the technical errors in creating the wrap, but its clinical merit remains unclear. Decreasing the scope diameter and adding multidirectional vision capabilities are needed for the 3D scope to gain more widespread approval and use in pediatric surgery.
