# Real-world effectiveness of a new powered stapling system with gripping surface technology on the intraoperative clinical and economic outcomes of gastrectomy for gastric cancer

## TL;DR

This study shows that a new powered stapling system with Gripping Surface Technology improves surgical outcomes and reduces costs during gastric cancer surgery.

## Contribution

Demonstrates real-world effectiveness of a new stapling system with Gripping Surface Technology in gastrectomy for gastric cancer.

## Key findings

- The GST group had significantly lower risks for intraoperative bleeding and anastomosis intervention.
- The GST system reduced cartridge consumption by one compared to the non-GST group.
- Multivariate analysis confirmed the benefits of GST on multiple intraoperative outcomes.

## Abstract

Surgical staplers have been widely used to facilitate surgeries, and this study aimed to examine the real-world effectiveness of a new powered stapling system with Gripping Surface Technology (GST) on intraoperative outcomes of gastrectomy for gastric cancer.

The data were extracted from the Fourth Hospital of Hebei Medical University’s (FHHMU) medical records system. Participants (N = 121 patients) were classified into the GST (n = 59) or non-GST group (n = 62), based on the use of the GST system. The intraoperative outcomes such as bleeding were assessed by reviewing video records. T-tests, Chi-square tests, and Mann–Whitney-U tests were used to compare the baseline characteristics between groups. Multivariate logistic regression was conducted for adjusting outcomes to study the effect of variables.

Compared with the non-GST group, the GST group had significantly lower risks for intraoperative bleeding, intraoperative anastomosis intervention rate, intraoperative suture, and intraoperative pression (aORs: 0.0853 (p < 0.0001), 0.076 (p = 0.0003), 0.167 (p = 0.0012), and 0.221 (p = 0.0107), respectively). The GST group also consumed one fewer cartridge than the non-GST group (GST:5 vs non-GST: 6, p = 0.0241).

The use of the GST system was associated with better intraoperative outcomes and lower cartridge consumption in Chinese real-world settings.
