Barbed suture gastropexy may shorten GDV surgery time in dogs

CURRENT FULL VERSION: A newly published Veterinary Surgery study adds fresh data to a practical question in canine GDV surgery: can barbed suture speed open gastropexy without giving up safety or durability? Reviewing 121 dogs treated for gastric dilatation-volvulus at Cornell, the authors found that open right-sided barbed suture gastropexy was associated with shorter operative time than standard incisional gastropexy when the gastropexy was the only procedure performed, while perioperative mortality, complications, and recurrence outcomes were similar between groups. (pubmed.ncbi.nlm.nih.gov)

The comparison matters because gastropexy is a core part of definitive GDV management, but surgeons still weigh efficiency against confidence in long-term fixation. ACVS notes that GDV surgery requires derotation, assessment of gastric and splenic viability, and permanent fixation of the stomach to the abdominal wall, all in patients that may already be unstable from shock, arrhythmias, or reperfusion injury. In that setting, even modest reductions in surgical time can be meaningful if they don't increase recurrence or postoperative complications. (acvs.org)

In the Cornell cohort, 58 dogs underwent barbed suture gastropexy and 63 underwent standard incisional gastropexy. The perioperative mortality rate across the full population was 5.79% with no significant difference between groups. When gastropexy was performed as the sole procedure, median surgical time favored the barbed approach, 53.3 minutes versus 62.6 minutes. The study also found no significant between-group differences in perioperative or postoperative surgical complications, recurrence of GDV, or gastric dilatation without volvulus. Postoperative gastrointestinal signs were reported in 23% of dogs overall, again without a significant difference by technique. The authors concluded that barbed suture gastropexy is a viable option for surgical management of GDV. (pubmed.ncbi.nlm.nih.gov)

The findings fit with earlier literature suggesting barbed sutures can improve efficiency in gastropexy. A prior laparoscopic study in 30 dogs found markedly shorter suturing and total surgery times with knotless barbed sutures than with traditional intracorporeal suturing, with no significant complications and intact gastropexies on follow-up imaging. Commentary accompanying that work described the barbed, knotless approach as quicker “with no downside,” while also cautioning that careful placement is needed to avoid penetrating the gastric lumen. Although that was a laparoscopic prevention setting rather than open GDV treatment, it supports the broader idea that barbed technology may reduce operative time in appropriately selected hands.

There is also useful context in the existing gastropexy outcomes literature. A large retrospective report on 766 prophylactic incisional gastropexies documented that barbed glycomer suture was already being used in a meaningful minority of cases, suggesting the material has been entering routine surgical practice beyond experimental settings. Meanwhile, earlier long-term follow-up data on incisional gastropexy found no GDV recurrence in the study cohort, but the authors cautioned that recurrence can still emerge years later and that losses to follow-up may underestimate true event rates. That caution is important here: the new Cornell paper is encouraging, but it doesn't settle the long-term durability question. (pmc.ncbi.nlm.nih.gov)

The study also lands in a broader surgical evidence landscape where speed and technical preference do not always clearly predict better outcomes. A recent Veterinary Evidence review on canine enterotomy closure found only weak evidence comparing Gambee with single interrupted sutures. Across three experimental clinical trials, simple interrupted closure was generally easier and faster, and one study suggested less stenosis and fewer adhesions, but another found no difference in postoperative complications, while Gambee closure showed higher leak pressures in one trial. The review’s practical conclusion was cautious: current evidence is too weak to recommend one pattern over the other, so technique choice still depends largely on surgeon judgment. That framing is relevant to the Cornell gastropexy data as well. A shorter procedure is attractive, but the more important question is whether that efficiency holds up without hidden tradeoffs over time.

For GDV specifically, perioperative decision-making starts well before the first suture. A retrospective acid-base analysis of 100 dogs with GDV found that traditional acid-base analysis was normal in 37% of dogs presenting within 1 hour, even though 89% had hyperlactatemia and semiquantitative analysis identified one or more abnormalities in every dog assessed that way. Mixed respiratory and metabolic acidosis was the most common traditional disorder, and the anion gap poorly reflected hyperlactatemia. The takeaway was straightforward: dogs with GDV often have multiple competing acidotic and alkalotic processes, so each patient needs individualized assessment rather than assumptions based on a single screening metric. That helps explain why even modest reductions in anesthesia or operative time can matter in these unstable cases, while also underscoring that surgical technique is only one part of the overall risk picture.

There is also a useful parallel from equine surgery on how outcome measures can shift depending on what matters most to owners and clinicians. In Thoroughbred broodmares that survived either large colon resection or colopexy, a retrospective study found no significant difference in subsequent reproductive success between procedures, and live foal per mare served rates were similar to national averages. The authors concluded that postoperative reproductive success should not drive intraoperative choice between those preventive strategies. Although the species and procedure are very different, the principle carries over: when short-term technical differences exist between surgical options, the clinically meaningful question is whether they change the outcomes owners ultimately care about.

A similar prognostic lesson appears in another recent small-animal surgery study, this time in dogs with perineal hernia. Investigators found that higher rectal dilatation scores immediately after surgery and at 60 days were associated with poorer outcomes, and that both persistent rectal dilatation and rectal wall fibrosis were linked to recurrence. Histology also showed greater inflammation and fibrosis in affected dogs than in controls. For surgeons, that study highlights the value of looking beyond the procedure itself to postoperative markers and tissue-level disease when estimating recurrence risk. In the GDV setting, the Cornell paper gives reassuring short-term comparative data on technique, but it does not yet offer that kind of deeper prognostic resolution.

Why it matters: For veterinary professionals, this study offers support for a technique decision that is often made in real time, under pressure, in unstable patients. If a barbed suture gastropexy can reliably trim operative time without worsening short-term outcomes, that could help surgeons reduce anesthesia exposure and streamline emergency workflow. But the practical takeaway isn't that one technique has definitively won. The study was retrospective, from a single institution, and focused on short-term outcomes plus recurrence tracking available through follow-up. For clinicians, the more useful interpretation is narrower: barbed suture appears to be a reasonable open GDV option in experienced hands, not a mandate to abandon standard incisional gastropexy. (pubmed.ncbi.nlm.nih.gov)

The paper also reinforces a point pet parents may not expect: even after successful surgery, recovery isn't always straightforward. ACVS notes that postoperative complications can include hypotension, hemorrhage, arrhythmias, shock, infection, dehiscence, and organ dysfunction related to reperfusion injury. The Cornell authors' finding that nearly one in four dogs had postoperative gastrointestinal signs, regardless of gastropexy type, aligns with that reality and may help teams set expectations for monitoring, discharge counseling, and longer-term follow-up.

What to watch: The next step is better long-term evidence, ideally prospective or multicenter, on recurrence, late gastric dilatation, and whether the time advantage with barbed suture persists across surgeons and case complexity. It would also be useful to know whether perioperative physiologic variables, including the mixed acid-base disturbances commonly seen in GDV, interact with surgical technique or recovery in ways not captured here. For now, the study gives clinicians another data point in favor of barbed suture as a credible option, but not yet the final word on durability. (pubmed.ncbi.nlm.nih.gov)
