Study compares barbed and standard gastropexy in dogs with GDV

CURRENT FULL VERSION: A Cornell-led study in Veterinary Surgery adds new comparative data to one of the most familiar decisions in emergency soft tissue surgery: how to perform the gastropexy once a dog with GDV is on the table. In 121 dogs treated surgically for gastric dilatation-volvulus, investigators found that open right-sided barbed suture gastropexy produced shorter surgical times than standard right-sided incisional gastropexy, with similar perioperative complications, recurrence rates, and persistent gastrointestinal signs on follow-up.

The backdrop is a procedure that’s already considered standard-of-care in GDV management. ACVS notes that once the stomach is derotated and viability assessed, the stomach is permanently affixed to the body wall to reduce the risk of recurrent volvulus. Even so, these patients can still face major complications tied to shock, reperfusion injury, arrhythmias, gastric necrosis, or splenic involvement, and some dogs will continue to experience gastric dilatation without volvulus after surgery.

That’s why technique questions still matter. The new study, from the Department of Clinical Sciences at Cornell University Hospital for Animals, retrospectively reviewed client-owned dogs with GDV that underwent either barbed suture gastropexy or standard incisional gastropexy. According to the abstract, the barbed suture technique was deemed a viable surgical option, and the authors highlighted shorter surgical times as its main differentiator. They also noted that persistent gastrointestinal signs remained possible regardless of technique. (pubmed.ncbi.nlm.nih.gov)

The finding lands in a literature base that has generally focused more on whether gastropexy prevents recurrence than on head-to-head comparisons of specific pexy methods in emergency GDV cases. A recent Veterinary Evidence knowledge summary reviewing recurrence after gastropexy found substantial variation in techniques and study quality across the published evidence. That review cites prior reports of recurrence after incisional gastropexy, but also underscores that recurrence appears uncommon overall when a gastropexy is performed, compared with much higher recurrence risk when GDV is treated without one.

There’s also relevant context from minimally invasive surgery. A 2017 PubMed-indexed study of total laparoscopic gastropexy using a single continuous barbed suture line in 63 dogs reported a median gastropexy surgery time of 70 minutes, with few short-term complications. That doesn’t make it directly comparable to the new open GDV paper, but it does support the broader idea that barbed suture constructs can be workable in veterinary gastropexy and may reduce some of the technical burden of suturing. A recent case report in Frontiers in Veterinary Science similarly described biomechanical and technical advantages proposed for self-anchoring barbed sutures, though that evidence remains early and procedural context differs. (pubmed.ncbi.nlm.nih.gov)

For veterinary professionals, the practical significance is less about declaring a winner than about expanding the evidence base around efficiency in a time-critical surgery. In GDV, shaving operative time can matter, but only if it doesn’t come at the cost of pexy integrity, postoperative complications, or recurrence. This study suggests barbed suture gastropexy may clear that first hurdle in one referral-center setting. Still, it’s a retrospective cohort study, so surgeon preference, case selection, case complexity, and changes in perioperative care over time could all influence the result. That caution is consistent with other veterinary surgery evidence reviews: for example, a Veterinary Evidence assessment of Gambee versus single interrupted closure after canine enterotomy found the available studies were small and methodologically weak, with mixed findings on speed, leak pressure, stenosis, and adhesions. Its bottom line was that no technique could be recommended confidently over the other, and that surgeon choice still drives practice when evidence is thin. (pubmed.ncbi.nlm.nih.gov)

The study also arrives as clinicians continue refining gastropexy technique more broadly. Prior work has looked at modified incisional approaches, laparoscopic-assisted methods, and long-term recurrence after incisional gastropexy, but comparative evidence remains patchy. That broader pattern shows up in other species and procedures too. In Thoroughbred broodmares surviving surgery for large-colon disease, a recent Veterinary Surgery retrospective study found no significant difference in later reproductive success between mares treated with large colon resection and those treated with colopexy; live foal-per-mare-served rates were similar between surgical groups and comparable to national studbook averages. The authors concluded that expected postoperative reproductive performance should not drive intraoperative choice between those preventive strategies. It’s a different clinical question, but the theme is familiar: when two accepted surgical approaches produce similar downstream function, efficiency, indication, and case specifics often become the deciding factors.

Another useful parallel comes from prognosis research rather than technique comparison. In dogs undergoing surgery for perineal hernia, a recent cohort and case-control study in The Veterinary Journal found that higher postoperative rectal dilatation scores and rectal wall fibrosis were associated with recurrence or incomplete resolution of clinical signs. The same study also showed more inflammation and fibrosis in affected dogs than in controls. For surgeons, that’s a reminder that long-term success is not only about which closure or fixation method is chosen, but also about identifying measurable postoperative or tissue-level factors that help predict which patients are at higher risk of failure. In GDV gastropexy research, standardized follow-up and clearer prognostic markers could be just as valuable as additional head-to-head technique comparisons.

In that sense, the Cornell paper is useful not because it settles the question, but because it gives surgeons a more current benchmark for discussing open-technique options with colleagues, trainees, and pet parents facing emergency consent decisions. (veterinaryevidence.org)

What to watch: The next step is external validation, ideally through multicenter or prospective studies that report exact operative time differences, complication definitions, and long-term follow-up in a standardized way, so practices can judge whether the time savings are clinically meaningful enough to influence protocol. It would also help to see future work pair technique comparisons with stronger prognostic data—similar to how postoperative rectal dilatation and fibrosis have been explored in perineal hernia—so clinicians can better separate procedure effects from patient-level risk.
