RESUMEN
The cranial sutures are proposed to be a stem cell niche, harbouring skeletal stem cells that are directly involved in development, homeostasis and healing. Like the craniofacial bones, the sutures are formed from both mesoderm and neural crest. During cranial bone repair, neural crest cells have been proposed to be key players; however, neural crest contributions to adult sutures are not well defined, and the relative importance of suture proximity is unclear. Here, we use genetic approaches to re-examine the neural crest-mesoderm boundaries in the adult mouse skull. These are combined with calvarial wounding experiments suggesting that suture proximity improves the efficiency of cranial repair. Furthermore, we demonstrate that Gli1+ and Axin2+ skeletal stem cells are present in all calvarial sutures examined. We propose that the position of the defect determines the availability of neural crest-derived progenitors, which appear to be a key element in the repair of calvarial defects.

In newborn humans, and up to approximately 2 y of age, calvarial bone defects can naturally regenerate. This remarkable regeneration potential is also found in newborn mice and is absent in adult mice. Since previous studies showed that the mouse calvarial sutures are reservoirs of calvarial skeletal stem cells (cSSCs), which are the cells responsible for calvarial bone regeneration, here we hypothesized that the regenerative potential of the newborn mouse calvaria is due to a significant amount of cSSCs present in the newborn expanding sutures. Thus, we tested whether such regenerative potential can be reverse engineered in adult mice by artificially inducing an increase of the cSSCs resident within the adult calvarial sutures. First, we analyzed the cellular composition of the calvarial sutures in newborn and in older mice, up to 14-mo-old mice, showing that the sutures of the younger mice are enriched in cSSCs. Then, we demonstrated that a controlled mechanical expansion of the functionally closed sagittal sutures of adult mice induces a significant increase of the cSSCs. Finally, we showed that if a calvarial critical size bone defect is created simultaneously to the mechanical expansion of the sagittal suture, it fully regenerates without the need for additional therapeutic aids. Using a genetic blockade system, we further demonstrate that this endogenous regeneration is mediated by the canonical Wnt signaling. This study shows that controlled mechanical forces can harness the cSSCs and induce calvarial bone regeneration. Similar harnessing strategies may be used to develop novel and more effective bone regeneration autotherapies.

The craniocervical junction (CCJ) forms the bridge between the skull and the spine, a highly mobile group of joints that allows the mobility of the head in every direction. The CCJ plays a major role in protecting the inferior brainstem (bulb) and spinal cord, therefore also requiring some stability. Children are subjected to multiple constitutive or acquired diseases involving the CCJ: primary bone diseases such as in FGFR-related craniosynostoses or acquired conditions such as congenital torticollis, cervical spine luxation, and neurological disorders. To design efficient treatment plans, it is crucial to understand the relationship between abnormalities of the craniofacial region and abnormalities of the CCJ. This can be approached by the study of control and abnormal growth patterns. Here we report a model of normal skull base growth by compiling a collection of geometric models in control children. Focused analyses highlighted specific developmental patterns for each CCJ bone, emphasizing rapid growth during infancy, followed by varying rates of growth and maturation during childhood and adolescence until reaching stability by 18 years of age. The focus was on the closure patterns of synchondroses and sutures in the occipital bone, revealing distinct closure trajectories for the anterior intra-occipital synchondroses and the occipitomastoid suture. The findings, although based on a limited dataset, showcased specific age-related changes in width and closure percentages, providing valuable insights into growth dynamics within the first 2 years of life. Integration analyses revealed intricate relationships between skull and neck structures, emphasizing coordinated growth at different stages. Specific bone covariation patterns, as found between the first and second cervical vertebrae (C1 and C2), indicated synchronized morphological changes. Our results provide initial data for designing inclusive CCJ geometric models to predict normal and abnormal growth dynamics.
RESUMEN
Flap fixation is the most promising solution to prevent seroma formation after mastectomy. In this systematic review with network meta-analysis (NMA), three different techniques were compared. The NMA included 25 articles, comprising 3423 patients, and revealed that sutures are superior to tissue glue in preventing clinically significant seroma. In addition, running sutures seemed to be superior to interrupted sutures. An RCT comparing these suture techniques seems necessary, given the quality and nature of existing literature.

BACKGROUND: There are limited data on the effect of different sutures and surgical approaches on the quality of pancreaticojejunostomy in minimally invasive pancreaticoduodenectomy (MIPD). This study compares the incidence of clinically relevant postoperative pancreatic fistula (CR-POPF) between the use of barbed sutures (BSs) and conventional sutures (CSs). METHODS: A retrospective cohort study was conducted on 253 consecutive patients who had undergone MIPD from July 2016 to April 2023. Patients were excluded if conversion to open surgery or open anastomosis was necessary. 220 patients were enrolled and divided into BS (n = 148) and CS (n = 72) groups. After 1:1 propensity score matching (PSM), 67 cases remained in each group. Univariate and multivariate analyses identified factors associated with CR-POPF. Comparisons were also made between laparoscopic (LPD) and robotic (RPD) pancreaticoduodenectomy. RESULTS: After PSM, BSs were associated with significantly lower rates of CR-POPF (7.5 vs. 22.4%, P = 0.015) and severe complications (Clavien-Dindo ≥ III) (7.5vs. 19.4%, P = 0.043). No significant differences were found in operative time, length of postoperative hospital stay, or other major morbidities. Multivariate analyses revealed BMI ≥ 22 kg/m2 (OR = 5.048, 95% CI: 1.256-20.287, P = 0.023) and the use of BSs (OR = 0.196, 95% CI: 0.059-0.653, P = 0.008) as the independent predictors of CR-POPF. There were no significant differences in postoperative outcomes between the LPD and RPD groups, but RPD was associated with significantly shorter operative time (402.8 min vs. 429.4 min, P = 0.015). CONCLUSIONS: In conclusion, using BSs for PJ during MIPD is feasible and has the potential to reduce CR-POPF and severe complications.
RESUMEN
BACKGROUND: Reduction of inflammation and early detection of complications after surgical procedures are important objectives for proper veterinary practice. This study aimed to evaluate the differences between shelter and pet female cats in selected acute-phase parameters scheduled to ovariohysterectomy. Postoperative monitoring after ovariohysterectomy with the same laboratory parameters was performed in shelter cats, in which two different types of surgical sutures were used for the entire procedure. The experimental group comprised 40 female cats from animal shelters ('shelter cats,' n = 40). These cats were divided into two subgroups: group A (n = 20) operated on with absorbable sutures and group NA (n = 20) operated on with non-absorbable sutures. In addition, the same parameters were evaluated in pet female cats (n = 19). Blood was collected from shelter cats immediately before surgery (term 0), at 24 and 72 h (terms 1 and 3, respectively), and at 7 and 14 days (terms 7 and 14, respectively) after ovariohysterectomy. Blood samples from the pet cat group were collected only once. RESULT: The mean haptoglobin concentration before ovariohysterectomy in pet cats was significantly lower than that in shelter cats. Fibrinogen concentration was significantly lower in pet cats than in cats from group A. Serum albumin, beta-1, beta-2, and gamma-globulin concentrations were significantly higher in the shelter cats than in the pet cats. Subcutaneous tissue thickening at the site of the postoperative wound was observed in five patients cats (25%) in group A, and two (10%) cats in the NA group. CONCLUSION: These results indicate that ovariohysterectomy leads to local and general inflammatory responses. The majority of cats from animal shelters suffered from subclinical inflammation.

Nowadays dog bite is becoming a world public health problem. Therefore, the study aimed to develop a dog bite animal model that is helpful to solve these problems. In this study, the skull of an adult dog was scanned. The three-dimensional model of the dog maxillofacial bones and dentition was built by MIMICS. Next, the model was printed with Co-Cr alloy by using selective laser sintering technology to develop the dog bite simulation pliers. Then, to simulate dog bite to most, the maximum bite force of the pliers was measured and actions contained in dog bite process was analyzed. Afterwards, according to action analysis results, rabbits were bitten by the prepared instrument in actions that simulate dog's bite. Finally, the reproducibility and controllability of this animal model of dog bite injuries was validated in an in vivo study. The results showed a reliable animal model of dog bite injuries has been developed in this study. The sites and severities of the injuries could be adjusted as the operator wishes and the animal model of dog bite injuries was highly repeatable. This study also indicates the feasibility of using digital technology in establishing animal bite models.

Purpose: To compare the clinical outcomes, feasibility, and safety between groups with sutured and sutureless wound closure in congenital ectopia lentis (CEL) patients. Methods: Patients with CEL who received phacoemulsification combined with intrascleral fixation of capsular hook (CH) and implantation of capsular tension ring (CTR) and in-the-bag intraocular lens (IOL) were included in this study. Results: A total of 68 eyes of 34 patients aged 18 years or younger were enrolled in this study. Incisions of 21 patients (34 eyes) did not require sutures while sutures were applied in 21 patients (34 eyes). Postoperative uncorrected distance visual acuity, best corrected distance visual acuity and intraocular pressure measurements were comparable on follow-up visits (P > 0.05). The magnitude of surgically induced astigmatism was significantly greater (P = 0.001) in the suture group (Median: 0.47; IQ: 1.63, 2.97) than in the sutureless group (Median: 0.88; IQ: 0.63, 1.35). No cases of endophthalmitis and retinal detachment were found postoperatively in either group, while suture-related complications were observed in the sutured group, including loose suture with discomfort in 5 (14.71%) eyes, loose suture with mucus infiltration in 3 (8.82%) eyes. In total, 22 sutures (64.71%) of 34 eyes required removal. Conclusions: Sutureless clear corneal incision in CEL patients can achieve satisfactory clinical results comparable to sutured wound closure in terms of the efficacy and safety. Advantages of this approach are the reduced risk of suture-related complications, no need for additional surgery under general anesthesia for suture removal, and less cost.

BACKGROUND: Intramural ectopic pregnancy is a rare form of ectopic pregnancy that occurs within the myometrium. It is challenging to diagnose it early because of its nonspecific clinical presentation, and there is no consensus or guideline on the optimal management among gynecologists. CASE PRESENTATION: We report a case of a 34-year-old woman who developed fundal intramural ectopic pregnancy after a previous caesarean section with B-Lynch suture. The B-Lynch suture was performed at 38 weeks of gestation for postpartum hemorrhage caused by refractory uterine atony about 8 years ago. Since then, the patient had oligomenorrhea. The diagnosis of intramural ectopic pregnancy was not confirmed by magnetic resonance imaging or ultrasound. An exploratory laparoscopy and hysteroscopy was performed to remove the gestational sac without significant bleeding. The surgery was successful and the patient recovered well. The patient was advised to monitor her ß-HCG levels regularly until they returned to normal, and a follow-up pelvic ultrasound showed no complications. However, she has not been able to conceive or have an ectopic pregnancy so far. CONCLUSIONS: This case illustrates the difficulty of diagnosing intramural ectopic pregnancy, especially when it is associated with previous uterine surgery and B-Lynch suture. It also demonstrates the feasibility and safety of laparoscopic surgery for treating complete IUP, especially when the gestational sac is located close to the uterine serosa. However, the risk of uterine rupture and hemorrhage should be considered, and the patient should be informed of the possible complications and alternatives. Gynecologists should be familiar with various management strategies and customize the treatment plan according to the patient's clinical situation and preferences.

INTRODUCTION: Severe congenital ptosis poses a complex challenge for oculoplastic surgeons, requiring meticulous surgical intervention to restore eyelid function and improve aesthetic outcomes mainly by using frontalis sling approach. A crucial issue in frontalis sling surgeries is the sustainability of effect. PURPOSE: This retrospective study reports the outcomes of two surgical techniques for treating severe congenital ptosis in the paediatric age group: Silicon rods ptosis sling and a novel technique involving the use of Silicon rods with green braided polyester (Ethibond) sutures to secure the rods in place "sling for the sling". METHODS: The medical records of children who underwent frontalis suspension were reviewed in a retrospective fashion. We identified two groups; the first group (20 patients: 35 eyelids) had the traditional frontalis suspension surgery using silicone suspension set, the second group (14 patients: 25 eyelids) was operated using the new "sling for sling" technique. We used the postoperative marginal reflex distance-1 (MRD-1) as the primary outcome measure while the frequency of both wound related complications and recurrence were considered as secondary outcome measures. Post operative data were collected and compared after 1 month, 6 months, 12 months, and 18 months. RESULTS: Preliminary results indicate promising outcomes for both techniques, with significant improvement in eyelid elevation observed in both groups. However, the novel technique using Silicon rods with Ethibond sutures demonstrated enhanced sustainability, leading to a more durable outcome with significantly less recurrence. CONCLUSION: This study highlights the potential benefits of the novel technique in treating severe congenital ptosis and introduces an innovative approach to Silicone rods fixation to achieve a long-term corrective effect.

PURPOSE: In craniofacial surgery, the stable fixation of transposed bone segments is crucial in order to ensure good long-term results. The use of absorbable material in fixation avoids the need for a second surgery, which would otherwise be required to remove osteosynthesis material. The authors of the present manuscript have already demonstrated that absorbable sutures ensure the stable fixation of bone segments in patients up to 24 months of age. However, it has thus far remained unclear whether stable fixation is possible in older patients by using only absorbable sutures due to the slower bone remodelling and prolonged healing time in this cohort. METHOD: For the present study, osteosynthesis was performed in 50 patients ranging from 25.7 to 192.1 months of age (mean, 61.4 ± 21.7 months) using solely absorbable sutures (PDS II®, Ethicon, Germany). Post-operative stability and possible restrictions-such as foreign body reactions-were evaluated within clinical and radiological routine follow-ups. RESULTS: All children demonstrated clinically and radiologically stable osteosynthesis both directly post-operatively and in follow-ups. No significant foreign body reaction could be seen. CONCLUSION: The present study demonstrates-for the first time-that absorbable sutures with a longer absorption period are also very well suited for the fixation of bone segments in patients over 24 months of age. The sole use of absorbable sutures in children over 24 months of age is a safe procedure with nearly no foreign body reactions. The procedure enables stable and highly cost-effective osteosynthesis without altering the osteotomy design.

This study evaluates contemporary wound closure techniques in spinal surgery, focusing on the efficacy of barbed sutures, skin staples, and negative-pressure wound therapy (NPWT), compared to traditional methods. Barbed sutures, like STRATAFIX™ Symmetric, and skin staples demonstrate significant advantages, including reduced wound closure time, lower infection rates, and improved surgical outcomes, particularly in multilevel or revisional procedures. In contrast, plastic surgery closures do not show a substantial reduction in postoperative complications despite being used in more complex cases. NPWT is highlighted as an effective adjunct therapy for managing surgical site infections and reducing the need for hardware removal. The findings suggest that while modern techniques offer clear benefits, traditional methods remain valuable in specific contexts. The review advocates for further research through large-scale, long-term studies and emphasizes the need for personalized wound closure strategies based on individual patient risk factors.

OBJECTIVE: To investigate if wearing surgical face mask by doctors and nurses during suturing of traumatic wounds has any impact on postoperative infection rate. DESIGN: Randomized controlled study with masked or unmasked health personnel groups. SETTING: A Norwegian Minor Injury Department. SUBJECTS: Adult patients with traumatic wounds sutured at the clinic between 7 October 2019 and 28 May 2020. MAIN OUTCOME MEASURES: Postoperative infections of sutured wounds. RESULTS: One hundred and sixty-five patients with 176 wounds were included in the study. Nine out of 88 wounds (10.2%) in the masked group and 11 out of 88 wounds in the unmasked group (12.5%) had a wound infection. CONCLUSIONS: Despite a higher percentage of postoperative infections in the unmasked than in the masked group (12.5% versus 10.2%), the difference was not statistically significant (p = .6). This might imply that the use of facemasks during suture of traumatic wounds in an outpatient setting does not significantly reduce the number of infections. However, due to the covid pandemic, the study had to be prematurely stopped before the planned number of participants had been recruited (n = 594). This increases the risk of type II error.
Few studies from hospital setting have found significant difference in postoperative wound infections if surgical face masks were worn or not during surgery.High quality studies about face masks and wound infections from primary care are lacking.This randomized study at a minor injury department outside hospital found no significant difference in frequency of postoperative wound infection if health personnel had worn surgical face masks or not while suturing traumatic wounds.

Bioabsorbable sutures can improve the medical functions of existing non-absorbable sutures, and may produce new medical effects, and are expected to become a new generation of medical degradable materials. In this study, the cytocompatibility of triclosan coated polyglactin910 sutures (CTS-PLGA910) was analyzed and different concentrations of sutures were prepared. The effects of sutures on the cytotoxicity and cell proliferation of HUVEC were studied by CCK-8 assay. The hemolysis, total antioxidant capacity (T-AOC) activity and nitric oxide (NO) content were investigated to improve the blood compatibility of sutures. The results showed that the hemolysis rate of CTS-PLGA910 was less than 5%. After treatment on HUVEC cells for 48 and 72 h, there was no significant change in NO content in CTS-PLGA910 groups compared with the control group, while T-AOC activity and antioxidant capacity were significantly increased in medium and high dose groups. In summary, the blood compatibility and cell compatibility were significantly improved, which provided a basis for the clinical application of sutures in the future.

BACKGROUND: Achieving an aesthetically pleasant tip rotation is paramount in rhinoplasty, and these results should be long-lasting. However, even powerful structural techniques such as septal extension grafts can lose rotation over time, as most support depends on the attachment of the graft to the septal cartilage. METHODS: We describe a simple suture technique to strengthen tip support in rhinoplasty, by suspending it to the cartilaginous dorsum, providing additional support to the tip against forces, such as gravity, scar contraction and muscle tension. CONCLUSIONS: Combining traditional techniques with suspension sutures can improve intraoperative results and could enhance long-term tip stability.

PURPOSE: This study aimed to formulate evidence-based recommendations for optimising wound management in hip and knee arthroplasty by exploring alternative methods such as barbed sutures and skin adhesives. METHODS: A Delphi panel, comprising seven orthopaedic surgeons, one musculoskeletal infectious disease specialist, and one health economics expert, was convened to evaluate the use of barbed sutures and skin adhesives for wound closure in hip and knee arthroplasty. Two systematic reviews informed the development of questionnaires, with panelists ranking their agreement on statements using a 5-point Likert scale. Consensus was achieved if ≥75% agreement. Unresolved statements were revisited in a second round. RESULTS: Consensus was reached on 11 statements, providing evidence-based recommendations. The expert panel advocates for a multilayer watertight technique using barbed sutures to prevent surgical site infections (SSI), reduce complications, shorten surgical times, optimise resources and improve cosmetic appearance. For skin closure, the panel recommends topical adhesives to decrease wound dehiscence, enhance cosmetic appearance, promote patient compliance, prevent SSIs, and optimise resources. CONCLUSION: The Delphi consensus by Italian total joint arthroplasty experts underscores the pivotal role of barbed sutures and skin adhesives in optimising outcomes. While guiding clinical decision-making, these recommendations are not prescriptive and should be adapted to local practices. The study encourages further research to enhance current evidence. LEVEL OF EVIDENCE: Level III.

OBJECTIVE: Cyanoacrylate tissue adhesive has been presented as an alternative to sutures and several studies have compared them. The objective of this meta-analysis was to evaluate the effect of cyanoacrylate tissue adhesive on postoperative pain and swelling, following mandibular third molar surgery. MATERIALS AND METHODS: Database search was conducted in MEDLINE/PubMed and Scopus, along with extensive search in the grey literature, including randomized and non-randomized clinical trials that applied cyanoacrylate adhesive for closing mandibular third molar surgical sites and compared it with silk sutures, assessing postoperative pain and swelling. The search ended on September 22, 2023. RESULTS: Of 886 identified articles, six were included and meta-analyzed. Applying cyanoacrylate demonstrated a reduction in the overall postoperative pain (SMD = -0.57, 95% CI -1.00 to -0.15, p = 0.009). A similar outcome was noted when pain was evaluated on the first and last postoperative days, based on controlled clinical trials (SMD = -0.47, 95% CI -0.92 to -0.03, p = 0.04), and randomized trials (SMD = -0.97, 95% CI -1.31 to -0.62, p < 0.00001). Patients/sides received cyanoacrylate showed a decrease in postoperative swelling (SMD = -0.26, 95% CI -0.51 to -0.01, p = 0.04). Following the GRADE rating system, the quality of evidence on pain and swelling was judged as moderate and low, respectively. CONCLUSIONS: The use of cyanoacrylate adhesive may offer benefit in reducing postoperative pain and swelling following mandibular third molar surgery. Nevertheless, this should be further investigated, considering the low number of included reports. CLINICAL RELEVANCE: The current results could help clinicians who perform this procedure to manage postoperative pain and swelling more effectively.

BACKGROUND: While barbed sutures have been extensively utilized in other disciplines, they have not been widely adopted in cardiac surgery. The lack of safety and feasibility data has limited its use within the field. To aide in the further understanding of how cardiac surgeons can use barbed sutures, we sought to develop a high-pressure in vitro simulation model. We compared knotless barbed sutures in a highly pressurized anastomosis to conventional sutures. METHODS: Ten specimens in total were utilized in prosthesis anastomosis, using 34 mm Gelweave Plexus (Terumo Aortic, Sunrise, FL 33325, USA) and 34 mm Hemabridge (Intergard Woven Hemabridge, Getinge, Göteborg, Sweden). Five models of size 3-0 barbed suture anastomoses using non-absorbable, barbed, self-retaining, monofilament polypropylene sutures (Filbloc® 3-0, Assut Europe, Rome, Italy) were compared against five conventional anastomoses using size 4-0 polypropylene monofilament (Ethicon, USA). The systems were connected using a novel-designed extracorporeal circulation system. Pressure was rapidly increased in the specimen to a mean pressure of 300-350 mmHg, running then for a minimum of 48 hours to assess anastomosis strength and endurance. RESULTS: No anastomotic dehiscence or rupture was recorded. Complex, angular anastomosis required extra stitch leakage sutures in both conventional and barbed suture specimens. CONCLUSION: Using knotless barbed sutures with an additional self-locking maneuver for prosthesis-prosthesis anastomosis in cardiac surgery is feasible in an in vitro model under long term, high-mean pressure when compared to conventional sutures. In vivo trials should be performed to further validate the in vitro findings.

BACKGROUND: STRATAFIX, a recently introduced barbed suture device, incorporates self-anchoring, knotless sutures with higher tensile strength and enhanced tissue-holding capacity compared to traditional braided absorbable sutures. This study aimed to compare the efficacy of barbed sutures and interrupted sutures in capsular and fascial closure during total hip arthroplasty. METHODS: We retrospectively reviewed the records of patients who underwent total hip arthroplasty between April 2017 and March 2021. Overall, 547 patients were evaluated, comprising 77 men and 470 women (mean age: 64.5 years). Among them, 330 patients were in the interrupted suture (control) group, while 217 were in the barbed suture (BS) group. Data on surgical time, perioperative hemoglobin, length of hospital stay, complications such as transfusions and delayed wound healing, and dislocation rates were collected during the latest outpatient follow-up and compared between the two groups. RESULTS: No differences were observed in intraoperative blood loss between the groups. However, the BS group exhibited significantly longer operative time, as well as significantly lower postoperative blood loss, total blood loss, and postoperative hemoglobin drop compared to the control group. Dislocation was reported in two cases within the control group, whereas no instances were recorded in the BS group. CONCLUSION: The use of barbed sutures demonstrated effectiveness in reducing perioperative blood loss for capsular and fascial closure during total hip arthroplasty.
RESUMEN
BACKGROUND: Studies have described various surgical maneuvers in rhinoplasty to limit thickening from excessive scarring in the supratip region. This study aimed to compare the effectiveness of three maneuvers-a simple suture, a U suture, and bolster dressing-used to avoid supratip deformity in a rabbit model. METHODS: Thirty-two male New Zealand white rabbits were included. The animals were divided into four groups, and dissection was performed in the supra-perichondrial plane up to the supratip region through an open rhinoplasty incision. After dissection, the following approaches were applied to the supratip region: Group 1, simple approximation suture; Group 2, U suture; Group 3, bolster dressing; and Group 4 (control group), no suture. All animals were sacrificed after 12 weeks. Histological analysis was performed. RESULTS: In Group 4, scar thickness was significantly greater than in the other groups (p < 0.05). Group 3 had greater scar thickness than Group 2 (p < 0.05). The ratio of scar thickness to skin thickness was higher in Group 4 compared with the other groups (p < 0.05). Finally, there was no difference in the ratio of scar thickness to skin thickness between Groups 1, 2, and 3 (p > 0.05). CONCLUSIONS: In this study, it was concluded that surgical methods using sutures in the supratip region reduced scar thickness in a rabbit model, and these surgical methods had similar levels of effectiveness.
