The study was conducted at the Small Animal Clinic of the Veterinary Faculty at the University of Ljubljana in Slovenia. The dogs had permanent dentition and were undergoing clinically indicated closed or open extractions. The investigators excluded animals with conditions or treatments that could impair wound healing, those requiring perioperative or postoperative antibiotics, and dogs with an oronasal fistula. No perioperative or immediate postoperative antibiotics or antiseptics were administered. All 87 animals were discharged on the day of surgery with pain management as clinically indicated, received a routine non-sedated examination 10 days later, and, if a healing complication was detected, underwent weekly in-person or telemedicine follow-up until healing was confirmed.

Dehiscence was defined by incomplete epithelial healing and separation of the wound edges, with defects of varying extent and granulation tissue accompanied by signs of inflammation. Investigators adapted a numerical scoring system for examination without sedation, meaning the assessment focused on wound-edge separation, gap size, and the presence of bridging granulation tissue. Features such as discharge, ulceration, necrotic tissue, debris, and inflammation could not be evaluated consistently in awake dogs and were not included in the score. Of the 17 affected sites, 13, or 76.5%, were classified as mild, while four had gaps larger than 10 mm that were not bridged by granulation tissue at the first examination.

Most complications involved large, functionally important teeth. Canine teeth accounted for six of the 17 affected sites, maxillary fourth premolars for four, and the mandibular first molar for one; together, these teeth represented 11 of 17 cases. Three affected dogs received antibiotics beginning five days after surgery, and one additional dog received extended analgesia because owners reported pain during eating. Two of the antibiotic-treated dogs had mandibular canine extraction sites, marked halitosis, and pain with eating. No affected site required revision surgery. After continued home-care measures, including soft food, avoidance of tooth brushing at the site, prevention of access to hard chew toys, and saline rinsing after meals, all wounds healed within 31 days.

Statistical analysis found several factors associated with dehiscence, although the observational design means these were associations rather than proof of causation. Each additional kilogram of body weight was associated with 13% higher odds of the complication, with an odds ratio of 1.13 and a 95% confidence interval of 1.04 to 1.23. Age was not associated with dehiscence. Compared with closed extractions, open procedures had nearly 17-fold higher odds, but that estimate had a wide 95% confidence interval of 2.11 to 141.91. The relatively small number of events and the strong relationship between surgical technique and procedural difficulty limit interpretation of these estimates.

Anatomical location also mattered. Sites in the rostral mandible, extending from the mandibular canine to the third premolar, had 23.25 times the odds of dehiscence seen in the incisive region, with a 95% confidence interval of 4.03 to 134.27. The rostral maxilla also had higher odds in the main model, although that difference did not remain significant after correction for multiple comparisons. The investigators proposed that persistent tension from the lower lip and perioral muscles may contribute to wound separation in the rostral mandible, but the study did not directly measure tissue tension. Caudal maxillary and mandibular sites were not significantly associated with dehiscence relative to the incisive region.

The extent of surgery showed a strong association. Removal of at least 50% of the alveolar bone was associated with nearly 19-fold higher odds of dehiscence compared with no buccal bone removal, although the 95% confidence interval was broad, from 2.36 to 151.59. Extractions for traumatic dentoalveolar injury had 9.20 times the odds associated with extractions for periodontal disease, while other extraction indications were not significantly associated. The authors suggested that fractured, periodontally healthy teeth may require more traumatic removal, whereas extensive bone removal may serve as a marker of extraction difficulty rather than being the sole cause of wound breakdown.

Flap design produced a notable but potentially confounded pattern. Among open extractions, triangular flaps were associated with higher estimated odds of dehiscence than envelope flaps. In the Bayesian model, the posterior median odds ratio was 4.44 for triangular versus envelope flaps among open procedures, with a 95% credible interval of 1.18 to 20.00. Pedicle flaps also had elevated estimated odds, but the estimate was imprecise because only five sites used that technique. Triangular flaps were more frequently used in procedures requiring removal of at least half the alveolar bone, so the researchers cautioned that the result may reflect extraction complexity and tissue trauma rather than flap design alone.

Other perioperative measurements did not show clear associations. Anesthesia duration, hypotension requiring a crystalloid bolus, and intraoperative root fracture were not significantly associated with dehiscence. Higher minimum body temperature was associated with greater odds in the primary model, but the relationship disappeared after adjustment for body weight, suggesting confounding. Root fracture occurred at 9.9% of extraction sites and involved 27.6% of the dogs, but fractured roots were successfully retrieved. The study also recorded two cases of late suborbital swelling after apparently uncomplicated healing, one linked to a subcutaneous foreign body and the other to panniculitis and myositis, showing that not every postoperative facial sign necessarily reflects the extraction wound itself.

Several limitations constrain the findings. The first examination occurred 10 days after surgery, so an earlier assessment might have detected more dehiscence while a later one might have missed mild cases that had already healed. Because examinations were performed without sedation, the investigators could not assess every tissue feature or bone healing consistently. The sample also came from one veterinary clinic, included only 17 dehiscence events, and contained relatively few pedicle-flap cases. Factors such as flap design, bone removal, extraction type, fracture, and body weight were interrelated, making it difficult to isolate the independent effect of any one factor. The authors called for more uniform canine populations and further prospective studies, while describing their cohort as the largest prospective clinical study of post-extraction wound-healing complications in healthy adult dogs reported to date.

The review, led by June Y. Moon, Yasir Al-Dojaily, Zahidul Islam, and Lucy Wang of New York Medical College’s Department of Dermatology, together with senior author Amor Khachemoune, systematically combed the published literature for reports on managing superficial cutaneous wound dehiscence. The search was deliberately broad, reaching beyond dermatology into other surgical specialties where wound separation has been studied in greater depth. What the authors found was sobering: after excluding a single-patient case report, the entire body of relevant comparative evidence amounted to just three studies covering 185 patients.

Those 185 patients were divided between two fundamentally different management philosophies. The first is secondary re-closure, in which a surgeon reintroduces sutures or other closure devices to bring the wound edges together again, sometimes after a period of wound preparation or delayed primary closure. The second is secondary intention healing, in which the wound is left open and allowed to fill in from the base through granulation tissue, contraction, and re-epithelialization. Each approach carries its own logic. Re-closure promises faster coverage and potentially better cosmesis but risks trapping bacteria and recreating the conditions that caused the separation. Secondary intention avoids foreign material in a potentially contaminated wound but demands weeks of dressing changes and leaves healing to the body’s slower processes.

The three studies that met the review’s criteria came from strikingly different clinical worlds. One was a randomized trial from obstetrics and gynecology, in which women with superficial dehiscence after gynecologic procedures were assigned to either secondary closure or healing by secondary intention. A second came from cardiothoracic surgery, examining superficial dehiscence after median sternotomy, the midline chest incision used to access the heart. The third was a retrospective case series in immunocompromised patients whose wounds were colonized by multidrug-resistant organisms, a population at extreme risk both from infection and from impaired healing.

Despite their differences, all three studies converged on a single descriptive finding: wounds that were re-closed healed faster than wounds left to heal by secondary intention. Two of the three studies also reported that re-closure required fewer clinic visits or fewer treatments, an outcome with real consequences for patients who face daily dressing changes over many weeks. In the sternotomy cohort, two closure failures were documented among the re-closed wounds, a reminder that suturing a previously opened wound back together does not always succeed. In the immunocompromised series, one late suture-associated abscess appeared, illustrating the infection risk that delayed closure is meant to mitigate but does not eliminate.

The authors are careful, and correctly so, to warn against over-reading these results. The studies differed substantially in design, wound characteristics, and how they reported outcomes, and none used the kind of rigorous, dermatology-specific framework that would allow confident generalization. The randomized trial did not provide detailed reporting of complications after re-closure, which makes a balanced risk assessment nearly impossible. Descriptive findings, the review emphasizes, do not establish superiority. A faster healing time in three heterogeneous, non-dermatologic cohorts is a signal worth investigating, not a treatment guideline.

For dermatologic surgeons, the gap is glaring. None of the three studies evaluated dehiscence after cutaneous surgery specifically, and none assessed cosmetic outcomes or patient satisfaction, two endpoints that matter enormously when the wound in question sits on a patient’s face, nose, or ear. Dermatologic surgery wounds differ in important ways from sternotomies or abdominal incisions: they are often smaller, frequently on sun-damaged skin with different biomechanics, frequently closed under significant tension on convex surfaces, and managed in an outpatient setting where healing is supervised by the operating surgeon rather than an inpatient team. Extrapolating from a 1992 obstetric trial or a cardiothoracic series to a nose defect after Mohs reconstruction is a leap that the evidence simply cannot yet support.

The biology of why wounds separate, and why they might behave differently when closed a second time, adds further nuance. Dehiscence usually follows a combination of factors: excessive tension across the closure, infection or hematoma beneath the surface, patient factors such as diabetes, smoking, immunosuppression, or advanced age, and mechanical forces from movement or trauma. Once the skin has opened, the wound bed is no longer a clean, surgically prepared plane. It is a contaminated, granulating surface colonized by bacteria, and the question of whether to close it becomes a question of whether the benefits of apposing the edges outweigh the risk of sealing microorganisms inside. The concept of delayed primary closure, well described in the plastic surgery literature, occupies the middle ground: the wound is managed briefly with dressings or negative pressure, then closed once it appears clean, theoretically capturing speed without sacrificing safety.

In practice, the review concludes, dermatologists currently manage dehiscence based on clinical experience, expert opinion, and extrapolation from other specialties. Many factors inform individual decisions: the size and depth of the wound, its location, the burden of contamination, the patient’s immune status and healing capacity, and the patient’s tolerance for repeated visits versus an open, healing wound. Some wounds on concave surfaces, such as the medial canthus or ear concha, are well suited to secondary intention and may heal with acceptable cosmetic results without re-closure. Others, under tension on convex surfaces, may benefit from being reapproximated once the infection risk is controlled. But the evidence base underlying any of these choices, when a wound actually opens, is essentially anecdote and judgment.

That is why the authors’ closing call for prospective dermatologic studies carries such weight. Wound dehiscence after skin surgery is common enough that well-designed trials, comparing re-closure against secondary intention with standardized measures of healing time, complication rates, cosmetic outcomes, and patient satisfaction, would be feasible and would transform a judgment-driven corner of practice into an evidence-based one. Until such trials exist, the review offers dermatologic surgeons something less satisfying but honest: a clear-eyed account of what is known, what is not, and where the field must go. When a wound separates, the surgeon’s hands may know what to do. The published literature, this review makes clear, does not yet.

Researchers at the Mayo Clinic conducted the analysis in accordance with the Cochrane Collaboration Handbook and the PRISMA reporting guidelines, registering the protocol prospectively in PROSPERO. Their search of PubMed, Embase, and the Cochrane Library yielded 1,479 records, which were screened independently by two reviewers down to just four eligible studies: three retrospective cohorts and one prospective cohort, together encompassing 8,944 adult patients undergoing body contouring procedures. Notably, semaglutide dominated the treatment landscape, accounting for more than 99 percent of prescriptions across the included studies, a detail that reflects how thoroughly one molecule has come to define the pharmacologic weight loss revolution.

The investigators focused their primary analysis on surgical site occurrences, a composite category capturing wound dehiscence, surgical site infection, seroma, and hematoma, the complications that most concern reconstructive surgeons operating on reshaped tissue. Secondary outcomes included readmission, emergency department visits, and gastrointestinal complications. Pooled risk ratios were calculated using random-effects models, with between-study heterogeneity quantified by the I² statistic, and leave-one-out sensitivity analyses were used to test whether any single study was driving the pooled results. Risk of bias was evaluated with the ROBINS-I instrument, and the certainty of evidence was graded using the GRADE framework.

The headline finding concerns wound dehiscence, the partial or complete separation of a surgical incision. Across the four studies, patients exposed to GLP-1 receptor agonists experienced wound dehiscence at a rate of 5.2 percent, compared with 2.9 percent among non-users. The pooled analysis produced a risk ratio of 1.62 with a 95 percent confidence interval of 1.09 to 2.42 and a p-value of 0.017, with no detectable heterogeneity, a statistically significant elevation in risk that carries real clinical weight. Dehiscence can prolong recovery, inflate healthcare costs, and undermine the aesthetic outcomes that motivate contouring surgery in the first place, so a 62 percent relative increase, if genuine, would matter to surgeons and patients alike.

Yet the story becomes considerably more complicated under scrutiny. When the researchers performed leave-one-out sensitivity analysis, the removal of a single large retrospective cohort by Lewis and colleagues, a study of nondiabetic post-bariatric patients treated exclusively with semaglutide, caused the wound dehiscence association to collapse to non-significance, with the pooled risk ratio falling to 1.02. In other words, the entire statistical signal appears to rest on one study. That cohort also reported higher overall complication rates than the other included trials, encompassing delayed wound healing, infections, nausea, vomiting, diarrhea, hypertrophic scars, and surgical site pain, and its authors had already recommended cautious perioperative planning, potential drug discontinuation before surgery, and nutritional optimization for patients on semaglutide undergoing post-bariatric contouring.

For every other outcome, the meta-analysis found no convincing signal of harm. Seroma formation showed no significant difference between users and non-users, with pooled rates of 9.2 percent versus 12.3 percent and a risk ratio of 0.78 that actually favored drug exposure. Hematoma rates were similarly indistinguishable, at 4.6 percent versus 2.6 percent, and surgical site infection showed no significant elevation at 5.3 percent versus 3.3 percent. Even the composite surgical site occurrence outcome, pooling all four studies, failed to reach significance, with rates of 13.9 percent versus 9.2 percent and wide confidence intervals. However, heterogeneity was high for seroma, infection, and composite outcomes, with I² values reaching 80.7 percent for the composite analysis, a statistical warning sign indicating that the underlying studies differed so substantially in populations, procedures, and definitions that pooling them may obscure more than it reveals.

Those differences are far from trivial. One included study restricted its analysis to lipoabdominoplasty, another to panniculectomy, while others spanned a broad range of contouring operations across the face, breast, trunk, and limbs. Treatment durations ranged from roughly 4.7 months to nearly four years, and perioperative discontinuation practices varied wildly: one study adhered to the American Society of Anesthesiologists protocol and stopped therapy one week before surgery, another reported an average discontinuation interval of 9.6 weeks with a range from zero to 100 weeks, and the remaining studies did not report discontinuation practices at all. Given that GLP-1 receptor agonists delay gastric emptying and raise theoretical aspiration risks under anesthesia, the absence of standardized perioperative protocols is itself a finding that should concern clinicians.

Physiologically, several mechanisms could plausibly link rapid pharmacologic weight loss to impaired wound repair. Aggressive weight reduction can precipitate relative malnutrition, depleting the protein stores and micronutrients essential for collagen deposition and tissue remodeling. There is also emerging evidence that GLP-1 receptor agonists may modulate inflammatory pathways and collagen synthesis, potentially affecting the mechanical integrity of healing incisions. Conversely, in diabetic patients, the improved glycemic control these drugs deliver may actually enhance wound healing and reduce infection risk, since obesity and hyperglycemia are well-established risk factors for postoperative complications. This inverse logic may explain why the study restricted to nondiabetic patients reported the worst outcomes, while studies with more metabolically diverse populations found neutral or even favorable effects. Prior bariatric surgery adds a further confounder, independently associated with nutritional deficiencies and impaired healing, and a separate comparison study found that bariatric surgery patients not taking GLP-1 drugs actually showed higher wound dehiscence and surgical site occurrence rates than matched drug users, hinting that the feared signal may partly reflect patient mix rather than the medication itself.

The quality assessment tempers optimism further. Using the ROBINS-I tool, the reviewers rated all included studies at moderate or serious risk of bias, with persistent problems in confounding, classification of interventions, missing data, and outcome measurement. Drug doses and timing were incompletely captured, outcome definitions were not standardized, and none of the studies had preregistered protocols, raising concerns about selective reporting. The authors themselves conclude that routine discontinuation of GLP-1 receptor agonists before body contouring surgery cannot yet be universally recommended, but that selective withholding may be appropriate, and that perioperative management should emphasize nutritional optimization, meticulous wound closure technique, multidisciplinary coordination with anesthesiologists and endocrinologists, and close postoperative surveillance for wound breakdown in active users.

What emerges is a portrait of a field racing to catch up with a medication revolution. With the population of patients on GLP-1 therapy expanding exponentially and body contouring demand rising in parallel, surgeons urgently need evidence-based guidelines for this new patient profile, yet the current evidence base consists of just four observational studies, none randomized, all carrying at least moderate bias risk. The investigators call for larger prospective studies with standardized protocols, ideally randomized controlled trials, that separately analyze patients with and without prior bariatric surgery, evaluate individual agents, doses, and treatment durations, and define optimal discontinuation strategies. Until such data arrive, the practical message for the millions of patients contemplating skin-removal surgery after their own pharmaceutical weight loss journey is one of measured reassurance: no consistent elevation in infections, fluid collections, or overall surgical complications has been demonstrated, but a possible, unconfirmed signal for wound dehiscence means the decision about when, whether, and how long to pause these drugs before going under the knife should be made deliberately, with a surgeon and endocrinologist at the table.

The commentary, authored by Syeda Bareera of Khyber Girls Medical College in Peshawar, Syed Hatim Hussain and Syed Muhammad Momin of Nowshera Medical College, Syed Muhammad Ahmad of Khyber Medical College, and Muhammad Fayyaz of Sphinghar University in Afghanistan, does not dismiss the original findings. Instead, the authors contend that the apparent link between GLP-1 receptor agonists and wound dehiscence may depend heavily on how drug exposure is defined, how rare outcomes are handled statistically, and whether wound risk is evaluated at the level of specific procedures rather than broad surgical categories. These three methodological distinctions, they argue, deserve far closer consideration before surgeons change practice or patients become alarmed. The commentary is a masterclass in the kind of critical appraisal that modern evidence-based medicine demands, particularly when a topic touches one of the most widely discussed drug classes in the world.

The first and perhaps most consequential point concerns the definition of exposure itself. The commentary authors emphasize that GLP-1 receptor agonist use should never be treated as a single, uniform perioperative exposure. There is a profound clinical difference between a patient who is actively taking a weekly injection in the days surrounding surgery, a patient who temporarily withheld the medication shortly before the operation, and a patient who discontinued therapy months earlier and has since achieved stable weight and nutritional status. Each of these scenarios carries a distinct physiological profile, and each could plausibly exert a different influence on wound healing. Yet in the studies included in the original meta-analysis, perioperative exposure timing was inconsistently reported at best. In some cohorts, cessation of the drug ranged from just one week before surgery to an average of 9.6 weeks, while in other cohorts the timing of discontinuation was not reported at all. This heterogeneity makes it genuinely difficult to know what the pooled estimates actually represent.

This ambiguity matters because clinical guidance on perioperative GLP-1 receptor agonist management has itself evolved rapidly. The initial recommendation from the American Society of Anesthesiologists advised holding weekly agents for one week before surgery, largely out of concern for residual gastric contents and aspiration risk during anesthesia. More recent multi-society guidance has shifted toward individualized assessment, weighing the timing of the last dose, the presence of gastrointestinal symptoms such as nausea and delayed gastric emptying, recent dose escalation, and patient-level risk factors. Against this moving target, the commentary authors argue that future studies must categorize exposure according to clinically meaningful perioperative windows: continued therapy, short-term withholding, prolonged withholding, or discontinuation after weight stabilization. They also suggest that investigators apply target trial emulation principles, a framework for causal inference from observational data championed by epidemiologist Miguel Hernán and colleagues, which aligns exposure assignment, follow-up, and outcome assessment with the causal question a randomized trial would ask. Only then, they contend, can observational analyses begin to disentangle the true effect of the drugs from the effects of weight change, nutrition, and timing.

The second methodological concern involves the statistical handling of rare events, a notoriously thorny problem in meta-analysis. In one of the included studies, led by Liang and colleagues, researchers reported zero surgical site infection events among GLP-1 receptor agonist users compared with seven events among controls, creating what statisticians call a single one-arm zero-event cell. Zero cells are poison for conventional risk ratio calculations, because dividing by zero is mathematically undefined and the choice of a continuity correction, a small artificial adjustment added to every cell, can materially change the pooled estimate. The original meta-analysis used Mantel-Haenszel random-effects risk ratios for binary outcomes, but the commentary authors note that it remains unclear whether a continuity correction was applied. They argue that a brief clarification of this analytic choice would help readers judge the robustness of the nonsignificant surgical site infection finding, and they cite the work of Xu and colleagues, who have proposed that meta-analysts select analytic methods according to the specific zero-event structure of their data rather than defaulting to a single approach.

Beyond clarification, the commentary authors recommend sensitivity analyses to test whether the nonsignificant infection finding survives alternative analytic conventions. These could include the Mantel-Haenszel risk difference, appropriate one-stage models, or Peto odds ratios, though the latter are only appropriate when groups are reasonably balanced and treatment effects are small. The point is not academic pedantry. When outcomes are uncommon and event counts are sparse, the apparent absence of a statistical signal can be an artifact of the analytic method rather than a genuine reflection of safety. For clinicians deciding whether to delay surgery or alter medication management, understanding the degree of uncertainty around nonsignificant findings is essential. The commentary authors argue that transparent reporting of these conventions would allow readers to interpret uncommon outcome estimates with appropriate caution, rather than mistaking statistical silence for evidence of no effect.

The third concern is arguably the most intuitive: the composite category of body contouring surgery may simply be too broad for an outcome as mechanically dependent as wound dehiscence. Panniculectomy, abdominoplasty, lipoabdominoplasty, brachioplasty, thighplasty, and mastopexy differ dramatically in incision length, flap tension, extent of undermining, dead space, drain use, and postoperative mechanical stress on the closure. High-tension abdominal procedures such as panniculectomy and abdominoplasty may involve broad dissection and challenging closure-tension dynamics, whereas mastopexy or brachioplasty involve entirely different anatomic sites, incision geometry, and postoperative forces. These factors are directly related to dehiscence risk and are not interchangeable across procedure types. Pooling them into a single body contouring category risks diluting or distorting any true procedure-specific signal, and the commentary authors argue that future work should stratify analyses by procedure type wherever sample size permits, particularly separating high-tension abdominal operations from other contouring procedures.

The commentary extends this procedural critique to the outcome definitions themselves. Surgical site occurrences, as commonly reported in the plastic surgery literature, combine events with fundamentally different mechanisms: infection, seroma, hematoma, and dehiscence. The Centers for Disease Control and Prevention’s National Healthcare Safety Network framework links surgical site infection surveillance to operative procedure category and tissue depth, while leading plastic surgery researchers such as Gabriel, Gupta, and Orgill have emphasized the clinical importance of distinguishing among these wound events rather than treating them as interchangeable. A pooled estimate that blends a seroma with a wound separation tells clinicians very little about either. The commentary authors call for predefined wound-event definitions, standardized follow-up intervals, and procedure-stratified analyses in future research, arguing that only this level of granularity will reveal which patients, which operations, and which perioperative management strategies genuinely warrant additional caution.

Crucially, the authors are careful to frame their critique as a call for cautious interpretation rather than a rejection of the original work. They acknowledge that the finding of a possible association between GLP-1 receptor agonist use and wound dehiscence is clinically important, particularly as plastic surgeons increasingly encounter patients arriving after pharmacologic weight loss, often with altered nutritional status, rapid changes in tissue quality, and complex medication histories. The current evidence, they write, is clinically valuable but limited by heterogeneity and variable reporting across the underlying primary studies. Their goal is to ensure that the dehiscence signal stimulates better-designed research rather than premature clinical dogma. In an era when a single headline about a blockbuster drug class can reshape patient behavior overnight, the distinction between a preliminary association and an established risk is not a technicality; it is the difference between informed decision-making and unnecessary alarm.

The broader lesson of this scholarly exchange extends well beyond GLP-1 receptor agonists and the operating room. It illustrates how the quality of a meta-analysis is ultimately bounded by the quality and granularity of the primary studies it pools, and how seemingly technical choices, the definition of an exposure window, the treatment of a zero cell, the boundaries of a surgical category, can shape conclusions that reach millions of patients. As the obesity medication revolution continues and the wave of post-weight-loss body contouring surgery swells, the surgical community now has both a warning and a roadmap: take the wound-healing question seriously, but answer it with the methodological rigor it demands. Patients contemplating surgery while on these medications should discuss timing and individual risk with their surgical and prescribing teams, guided by evolving multi-society recommendations rather than by any single pooled estimate.
