Handsewn semiclosed single-layer jejunocecal side-to-side anastomosis in the horse.

This research article discusses a new technique for semiclosed single-layer jejunocecal anastomosis in horses, providing a quicker and safer method to restore intestinal continuity during colic related surgeries. It suggests that this new method reduces operation time and minimizes mucosal exposure, offering a beneficial alternative to the conventional handsewn two-layer technique.

Research Methodology

The study was divided into two parts:

• In vitro experimentation: The researchers obtained intestinal specimens from 24 horses immediately post-mortem at a slaughterhouse.
• Clinical case study: They examined 10 live horses that exhibited clinical signs of colic requiring jejunocecostomies.

Additionally, they compared the duration and the stability of this semi-closed (SC) anastomosis method with that of the traditional two-layer handsewn (HS2L) method. They also recorded the mean bursting pressures of the anastomoses to provide a measure of their relative strength.

Results of the Study

The SC technique demonstrated substantial advantages in different aspects:

• Speed: The SC method was significantly faster than the HS2L technique.
• Safety: It was successfully performed in 10 clinical cases needing jejunocecal anastomosis, with only a single major complication—obstruction from kinking of the anastomosis—reported.
• Minimized exposure: It exposed significantly less of the mucosal layer compared to the HS2L method.

Final Conclusion

Based on the results, the study endorses the use of the SC technique for jejunocecostomies in horses. The researchers cite the time-efficiency and safety of the procedure, as well as the minimized mucosal exposure, as reasons to prefer this method over the traditional HS2L technique. The SC technique thus provides a new method for veterinary surgeons to consider when performing such surgeries on horses.
