Case report highlights Roux-en-Y bypass for equine pyloric obstruction

A new Equine Veterinary Journal case report describes Roux-en-Y gastrojejunostomy combined with side-to-side jejunojejunostomy as a pyloric obstruction bypass option in two equine patients, one adult horse and one foal. The authors report that both cases recovered well long term, and they argue the modified approach may reduce some of the complications seen with more conventional bypass procedures used for gastric outflow obstruction in horses. The report adds to a small but growing body of literature on surgical options for rare, high-stakes pyloric and pyloroduodenal obstruction cases in equine practice. (madbarn.com)

Why it matters: For equine surgeons and referral teams, pyloric obstruction remains uncommon, but it can be difficult to manage and carries a guarded reputation because standard bypass techniques may be followed by delayed gastric emptying, recurrent colic, poor weight gain, or other postoperative complications. Earlier reports in foals and adult horses have shown that gastrojejunostomy, with or without jejunojejunostomy, can be lifesaving and may support long-term survival, but outcomes have been variable. This new two-case report suggests a Roux-en-Y configuration could be a useful alternative when the goal is to bypass the pylorus while limiting bile reflux and other functional problems associated with simpler bypass constructs.

What to watch: Whether additional case series confirm that this approach improves postoperative function and durability compared with standard gastrojejunostomy in horses and foals. (madbarn.com)
