ARTICLE HIGHLIGHTS
Research background

Three-dimensional (3D) laparoscopy provides a 3D sense of depth and layering that allows surgeons to obtain a field of vision similar to open surgery. 3D laparoscopic techniques are gradually being applied in the treatment of carcinoma in the remnant stomach (CRS), but their clinical efficacy remains controversial.

Research motivation

There are limited reports and studies about the application of 3D laparoscopic-assisted techniques in the treatment of CRS. No study has shown whether 3D laparoscopic-assisted gastrectomy (3DLAG) is superior or non-inferior to open gastrectomy (OG) for CRS.

Research objectives

This study retrospectively collected the clinical data of 3DLAG and OG in the treatment of CRS, analyzed the short-term and long-term efficacy of the two methods, and provided a reference for the minimally invasive treatment of CRS.

Research methods

The authors retrospectively evaluated 84 patients with CRS who had undergone OG for carcinoma or 3DLAGC at the First Medical Center of Chinese PLA General Hospital from January 2016 to January 2021. The short-term and long-term outcomes were compared between the OG (n = 48) and 3DLAG (n = 36) groups.

Research results

Compared with the OG group, the 3DLAG group had less surgical trauma and faster recovery after surgery. However, the complication rate and intensive care unit admission rate were equivalent between the two groups. The 1-year overall survival (OS) and 3-year OS rates were similar between the two groups, which suggested comparable long-term survival results between the groups. Our research showed that 3DLAG for CRS can be promoted safely and effectively in selected patients.

Research conclusions

Compared with OG, 3DLAG for CRS can achieve better short-term efficacy and equivalent oncological results without increasing clinical complications.

Research perspectives

Prospective randomized controlled trials with large samples and multiple centers are needed in the future.
