Study finds barbed suture gastropexy may shorten GDV surgery: full analysis

CURRENT FULL VERSION: A newly published Veterinary Surgery study adds fresh data to a familiar emergency-surgery question: can barbed suture gastropexy speed up GDV surgery without compromising outcomes? In a retrospective review of 121 client-owned dogs treated at Cornell University Hospital for Animals, researchers found that open right-sided barbed suture gastropexy produced similar perioperative mortality, complication rates, and recurrence outcomes compared with standard incisional gastropexy, while shortening procedure time when the gastropexy was performed as the sole procedure.

That question matters because gastropexy is a standard part of surgical management for GDV, a life-threatening condition in dogs that requires rapid stabilization and surgery. The American College of Veterinary Surgeons notes that once the stomach is returned to normal position, it is permanently affixed to the abdominal wall, and that postoperative risks can include hypotension, hemorrhage, arrhythmia, infection, dehiscence, shock, and death. In other words, even modest gains in operative efficiency can be meaningful in a high-acuity setting. (acvs.org)

In the new study, the authors compared 58 dogs treated with barbed suture gastropexy and 63 treated with standard incisional gastropexy. The overall perioperative mortality rate was 5.79% across the cohort, with no statistically significant difference between groups. The main difference was speed: when gastropexy was the only procedure performed, the barbed suture approach averaged 53.3 minutes, compared with 62.6 minutes for standard incisional gastropexy. Rates of perioperative and postoperative surgical complications, recurrence of GDV, and gastric dilatation without volvulus were not significantly different between techniques. The authors concluded that barbed suture gastropexy is a viable option for GDV management, while also noting that persistent gastrointestinal signs can still occur regardless of technique.

The findings fit with earlier veterinary surgery literature suggesting that barbed sutures can reduce suturing time in gastropexy. In one earlier controlled clinical trial summarized by Clinician’s Brief, laparoscopic gastropexy using self-anchoring barbed sutures had shorter suturing and total surgery times than traditional intracorporeal knot tying, with no significant complications reported in that small cohort. Other published series have also described acceptable short-term outcomes with barbed-suture laparoscopic gastropexy. This doesn’t make the current Cornell study definitive, but it does suggest the time-saving signal is biologically and technically plausible across settings. (files.brief.vet)

That broader pattern is not unique to gastropexy. A separate Veterinary Evidence review looking at Gambee versus single interrupted closure after canine enterotomy found the evidence base to be weak and methodologically limited, based on three experimental clinical trials. Across those studies, simple interrupted closure was generally easier and faster, with one study also suggesting lower stenotic index, fewer adhesions, and faster gain in tensile strength, while another found no difference in postoperative complications and a third reported higher initial and maximum leak pressures with Gambee despite longer closure time. The review’s bottom line was cautious: current evidence is too weak to recommend one technique over the other, so the choice remains largely surgeon dependent. That is a useful reminder that in veterinary soft tissue surgery, apparent technical advantages such as speed do not always translate into a clearly superior clinical standard without stronger comparative data.

The larger evidence base on recurrence remains less robust. A 2025 Veterinary Evidence knowledge summary reviewing 16 studies concluded that recurrence of GDV after gastropexy appears low, but the overall strength of evidence is weak because of methodological limitations across the literature. That context is important: this new paper strengthens the case that barbed suture gastropexy performs similarly to standard incisional gastropexy in the short term, but it doesn’t settle the question of long-term superiority.

Why it matters: For surgeons and emergency teams, the practical takeaway is that barbed suture gastropexy may offer a way to streamline one part of GDV surgery without obvious compromise in safety or recurrence risk. In a disease where patients may already be hemodynamically unstable, shaving minutes off a procedure can matter operationally and clinically, even if the study was not designed to prove downstream survival benefits from shorter anesthesia time. For general practices and referral centers considering protocol changes, the paper supports barbed sutures as a reasonable technique option rather than a clear new standard of care. It also fits a wider evidence pattern in veterinary surgery: many suture-technique comparisons suggest possible efficiency differences, but the supporting studies are often too limited to justify strong claims of superiority.

There’s also a training and adoption angle. Nicole Buote’s group at Cornell has been active in minimally invasive and advanced soft tissue surgery, and the new report may encourage more clinicians to revisit where barbed sutures fit in open emergency procedures, not just prophylactic or laparoscopic gastropexy. Still, decisions around suture choice will likely continue to depend on surgeon familiarity, material cost, availability, and comfort with handling characteristics in compromised tissue. That last point is an inference based on how surgical techniques are typically adopted, rather than a direct finding of the study. (pubmed.ncbi.nlm.nih.gov)

What to watch: The next meaningful development would be prospective, ideally multicenter, comparisons that include longer-term follow-up, standardized complication reporting, and measures such as anesthesia duration, total case time, cost, and surgeon learning curve. As the enterotomy literature also illustrates, future studies need to be designed well enough to distinguish between a technique that is simply faster and one that is meaningfully better for patients. If those data hold up, barbed suture gastropexy could move from a viable alternative to a more widely preferred workflow choice in GDV surgery. (pubmed.ncbi.nlm.nih.gov)
