Effects of staple size, tissue thickness, and precompression time on staple shape in side-to-side jejunocecal anastomosis in specimens obtained from healthy horses at an abattoir.
Abstract: To determine effects of staple size, precompression time, and tissue thickness on staple shape and tissue approximation in side-to-side jejunocecal anastomosis in equine specimens. Methods: Cecum, ileum, and jejunum specimens obtained from 18 healthy horses at an abattoir. Methods: Specimens were allotted into 2 groups. Anastomoses were stapled with 4.8-or 3.8-mm staples. Precompression time was 15 seconds for both groups. Staple lines were cut into proximal, middle, and distal sections. Thickness of intestinal walls was measured with a calibrated tissue micrometer, photographs were obtained, and intestinal tissues were digested. An investigator measured staples and assessed the shape of staples on high-definition digital images. Number of optimally shaped staples and staple height were compared among sections and between groups. Results: Use of 4.8-mm staples resulted in poor approximation of tissues in the distal sections of anastomoses. The percentage of optimally shaped staples was 538 of 551 (97.6%) and 616 of 634 (97.2%) for 4.8- and 3.8-mm staples, respectively. The percentage of optimally shaped staples did not differ significantly between groups for the same sections. There was a lower percentage of optimally shaped staples in the distal sections than in the proximal and middle sections of each group. Mean staple height did not differ significantly among sections of each group. Conclusions: Use of 3.8-mm staples with an adequate precompression time for jejunocecal anastomosis in horses resulted in proper staple shape. These findings could be used to improve the technique and outcome for stapled jejunocecal anastomoses in horses.

The research article investigates the influence of staple size, precompression time, and tissue thickness on staple shape and tissue approximation in the surgical process of side-to-side jejunocecal anastomosis in horses.
Research Methodology
- The research was conducted on cecum, ileum, and jejunum specimens sourced from 18 healthy horses at an abattoir.
- The anastomoses were stapled with either 4.8 or 3.8-mm staples. For both groups, a precompression time of 15 seconds was followed.
- The researchers dissected the staple lines into proximal, middle, and distal sections.
- They then measured the thickness of the intestinal walls using a calibrated tissue micrometer, took photographs, and digested the intestinal tissues.
- An investigator gauged the staples and evaluated the shape of staples using high-definition digital images.
- The number of optimally shaped staples and the staple height were compared across sections and between groups.
Research Findings
- The research found that using 4.8-mm staples led to poor tissue approximation in the distal sections of the anastomoses.
- For 4.8-mm staples, 97.6% (538 of 551) were optimally shaped, while for 3.8-mm staples, 97.2% (616 of 634) staples were optimally shaped.
- No significant differences were observed in the percentage of optimally shaped staples between groups for the same sections.
- The distal section had a lower percentage of optimally shaped staples compared to the proximal and middle sections within each group.
- There was no significant difference in the mean staple height among sections within the same group.
Conclusions
- The research concluded that the use of 3.8-mm staples, combined with an adequate precompression time, resulted in the proper staple shape for jejunocecal anastomosis in horses.
- These results could be employed to enhance the technique and outcome for stapled jejunocecal anastomoses in horses.
