A novel magnetic compression technique for small intestinal end-to-side anastomosis in rats

Abstract

Abstract

Background

Magnetic compression technology is a safe and convenient digestive tract reconstruction technique in large animals. The purpose of this study was to verify the feasibility of using the micromagnetic ring for construction of small intestinal end-to-side anastomosis in rats.

Methods

Thirty male Sprague–Dawley albino rats were randomly divided into two groups: a study group that underwent small intestinal anastomosis with micromagnetic ring and a control group that had hand-sewn anastomosis. The time to construct the anastomosis, survival rate and incidence of complications were compared between the two groups. The anastomotic segments in each group were harvested on day 28 after surgery and investigated.

Results

The mean anastomosis construction time was significantly lower in the study group than the control group (6.80 ± 1.97 min vs. 16.13 ± 3.29 min, P
