Background The availability of Mohs micrographic surgery (MMS) in Australia has increased dramatically since its inception in the 1980s. Objective This study aimed to describe the evolution of MMS practices at the Skin and Cancer Foundation Australia (SCFA) over the past 20 years (1997-2017). Methods Retrospective analysis of Mohs surgery cases at SCFA in 2017, 2007, and 1997, comparing data on sex, age, tumor type and site, initial tumor and final defect size, number of surgical stages and sections, and closure management. The present study is limited by being a retrospective analysis from a single institution. Results There was a 415% increase in the number of Mohs surgery cases from 1997 to 2017, and a significant increase in Mohs surgery-treated squamous cell carcinoma. The preoperative tumor and final defect size have decreased. More side-to-side closures and fewer grafts are being performed over time. Limitations Retrospective analysis from a single institution. Conclusion Over the last 20 years, MMS has remained appropriate in its application and is being increasingly used for treatment of squamous cell carcinoma suggesting improved access.

Wound complications after pediatric spinal deformity surgery are a relatively common and challenging complication that results in emotional, physical, and monetary costs to the patients, families, and healthcare providers. The role of wound closure techniques for the prevention of wound complications is being increasingly explored. Interdisciplinary care by spinal surgeons and plastic surgeons has been recently found to decrease wound complication rates in patients with nonidiopathic scoliosis.

Emergency department (ED) providers spend a significant amount of time treating low-acuity medical conditions, such as simple laceration repairs. Lacerations account for 5% of all ED visits in the United States (). An extended period of time by the provider is required for traditional wound repair, and there is perceived pain reported by patients (). The closure devices (Zip Closure device) are a latex-free, noninvasive alternative to staples, sutures, and glue and make wound closure an easy, fast process, allowing patients to remove the device after the wound has healed. The purpose/aim of this quality improvement project was to implement and evaluate the effectiveness of a noninvasive wound closure technique in the ED. The specific aims were to determine whether the Zip Closure device resulted in cost savings for the facility by decreasing the provider time that was needed for the laceration repair and determine whether there was an improved patient satisfaction compared with traditional wound closure methods. Following provider education regarding the use of the Zip Closure device, the device was available to providers over a 4-month period of time for use with patients in the ED. There were 63 lacerations seen in the ED during the 4 months of the quality improvement project, and an evaluation note was completed by a provider on all wounds. Six subjects were treated with the Zip Closure device, and 5 expressed satisfaction with the device. Providers stated that barriers to using the product on more wounds were that the lacerations were nonlinear, complex, high tension, and superficial or involved the finger, hand, scalp, face, or mouth; therefore, the device was inappropriate for treatment of the laceration. This was preliminary work of the noninvasive wound closure device. It is recommended that the study be repeated in a larger ED setting.

OBJECTIVE To determine what factors increase the risk of early wound complications in patients undergoing direct anterior total hip arthroplasty whose wounds were closed with 2-octyl cyanoacrylate with mesh. METHODS This study was a retrospective review of 75 consecutive patients who underwent direct anterior total hip arthroplasty closed with 2-octyl cyanoacrylate with mesh. MAIN RESULTS Of 29 patients who were smokers, five patients (17.2%) developed a wound complication, whereas out of 46 nonsmokers, only one patient (2.2%) developed a wound complication (P = .029). CONCLUSIONS The authors recommend a closure technique that sufficiently protects the wound during healing, as well as preoperative patient optimization and smoking cessation.

The union rate of wire fixation after median sternotomy remains unsatisfactory. We developed a novel osteoconductive sheet composed of hydrophilized hydroxyapatite and evaluated its osteogenetic effect when interposed between sternal halves in a canine model. Eighteen canines were divided equally into groups based on the hemostatic agent used: osteoconductive sheet (S), none (C), and bone wax (BW). After median sternotomy, the sternal halves were closed by wire fixation. In each group, 3 canines were euthanized at 1 month, while 3 were euthanized at 2 months. Resected sternums were mechanically assessed by the 3-point bending test, radiographically assessed by micro-CT, and pathologically assessed to quantify the osteogenesis between sternal halves. Compared with the BW group, the S group had a greater maximum stress at 1 month (S: 322.9 ± 107.7 N, C: 233.0 ± 62.7 N, BW: 124.9 ± 88.4 N; P = 0.025), and greater maximum shear force at 1 month (S: 1.92 ± 0.67 N/m2; C: 1.23 ± 0.28 N/m2; BW: 0.68 ± 0.41 N/m2; P = 0.025). Micro-CT revealed that the S group had more osteogenesis than the BW group at 1 month (25.7% ± 9.8% vs 6.9% ± 9.2%), and 2 months (34.0% ± 15.1% vs 14.8% ± 9.4%); the respective values in the C group were 17.1% ± 7.2% and 29.7% ± 9.3%. Pathologic examination revealed that the S group had the greatest osteogenetic area at 2 months (S: 38.8% ± 18.8%; C: 24.5% ± 6.9%; BW: 24.7% ± 18.6%). Adjuvant osteoconductive therapy using a cotton-like hydroxyapatite sheet in addition to wire fixation significantly improved sternal healing compared with BW. This new material also showed relatively better outcome than the C group.

Our multi-institutional university consortium implemented a gastroschisis pathway in 2015 to standardize and improve care by promoting avoidance of routine intubation and paralysis during silo placement, expeditious abdominal wall closure, discontinuation of antibiotics/narcotics within 48 h of closure, and early initiation/advancement of feeds.Adherence to the gastroschisis pathway was prospectively monitored. Outcomes for the contemporary cohort (2015-2018) were compared with a historical cohort (2007-2012).Good adherence to the pathway was observed for 70 cases of inborn uncomplicated gastroschisis. The contemporary cohort had significantly lower median mechanical ventilator days (2 versus 5; p 0.01) and antibiotic days (5.5 versus 9; p 0.01) as well as earlier days to initiation of feeds (12 versus 15; p 0.01). However, no differences were observed in length of stay (28 versus 29 days; p = 0.70). A skin closure technique was performed in 66% of the patients, of which 46% were performed at bedside without intubation, the assistance of an operating-room team, or general anesthesia.In this study, adherence to a clinical pathway for gastroschisis across different facilities was feasible and led to reduction in exposure to mechanical ventilation and antibiotics. The adoption of a bedside skin closure technique appears to facilitate compliance with the pathway.Level II/III TYPE OF STUDY: Prospective comparative study with historical cohort.

Skull base reconstruction after an endoscopic endonasal approach into the cerebrospinal fluid (CSF) space is always challenging. Various reconstructive methods are available, but no standard technique is established. This report describes the endoscopic skull base dural closure using a modified nonpenetrating clip device with shaft length of 15 cm. Six patients with an intra-suprasellar or suprasellar tumor who underwent extended endoscopic endonasal transsphenoidal surgery were targeted. For closure of the skull base dural defect after tumor removal, fascia lata was first placed as an inlay graft and was subsequently fixed with the dura using a modified nonpenetrating clip device. No CSF leakage from the closed dura with an inlay fascia lata fixed with clips was confirmed by the Valsalva maneuver. To complete skull base reconstruction, fascia lata was then positioned as an overlay graft and covered with vascularized pedicled nasoseptal flaps. Five of six patients experienced no CSF rhinorrhea postoperatively. The modified nonpenetrating clip device may achieve effective dural closure in the deep and narrow nasal cavity. We introduce this clip device technique as one of the endoscopic skull base dural closure methods.

Summary: Background: Many techniques have been developed to prevent postoperative pancreatic fistula (POPF) after distal pancreatectomy, but POPF rates remain high. The aim of our study was to analyze POPF occurrence after closure of the pancreatic remnant by different operative techniques. Methods: Between 2006 and 2017, 284 patients underwent distal pancreatectomy in our institution. For subgroup analysis the patients were divided into hand-sewn (n = 201) and stapler closure (n = 52) groups. The hand-sewn closure was performed in three different ways (fishmouth-technique, n = 27; interrupted transpancreatic U-suture technique, n = 77; common interrupted suture, n = 97). All other techniques were summarized in a separate group (n = 31). Results were gained by analysis of our prospective pancreatic database. Results: The median age was 63 (range 23–88) years. 74 of 284 patients (26%) were operated with spleen preservation (similar rates in subgroups). ASA-classes, median BMI as well as frequencies of malignant diseases, chronic pancreatitis, alcohol and nicotine abuse were also comparable in the subgroups. Neither the rates of overall POPF (fishmouth-technique 30%, common interrupted suture 40%, stapler closure 33% and interrupted U-suture 38%) nor the rates of POPF grades B and C showed significant differences in the subgroups. However is shown to be associated with pancreatic function and parenchymal texture. Conclusion: In our experience the technique of pancreatic stump closure after distal resection did not influence postoperative pancreatic fistula rate. As a consequence patient specific reasons rather than surgical techniques may be responsible for POPF formation after distal pancreatectomy.

BACKGROUND The timing of coverage of an open wound is based on heavily on clinical gestalt. DoD's Surgical Critical Care Initiative created a clinical decision support tool that predicts wound closure success using clinical and biomarker data. The military uses a regimented protocol consisting of serial washouts and debridements. While decisions around wound closure in civilian centers are subject to the same clinical parameters, preclosure wound management is, generally, much more variable. We hypothesized that the variability in management would affect local biomarker expression within these patients. METHODS We compared data from 116 wounds in 73 military patients (MP) to similar data from 88 wounds in 78 civilian patients (CP). We used Wilcoxon rank-sum tests to assess concentrations of 32 individual biomarkers taken from wound effluent. Along with differences in the debridement frequency, we focused on these local biomarkers in MP and CP at both the first washout and the washout performed just prior to attempted closure. RESULTS On average, CP waited longer from the time of injury to closure (21.9 days, vs. 11.6 days, p < 0.0001) but had a similar number of washouts (3.86 vs. 3.44, p = 0.52). When comparing the wound effluent between the two populations, they had marked biochemical differences both when comparing the results at the first washout and at the time of closure. However, in a subset of civilian patients whose average number of days between washouts was never more than 72 hours, these differences ceased to be significant for most variables. CONCLUSION There were significant differences in the baseline biochemical makeup of wounds in the CP and MP. These differences could be eliminated if both were treated under similar wound care paradigms. Variations in therapy affect not only outcomes but also the actual biochemical makeup of wounds. LEVEL OF EVIDENCE Therapeutic, level IV.

Background Component separation technique (CST) allows fascial medialization during abdominal wall reconstruction (AWR). Wound contamination increases the incidence of wound complications, which multiplies the incidence of repair failure. The aim of this study was to compare the impact of CST on AWR outcomes in contaminated fields in comparison to those operations without CST. Methods A prospective, single institution hernia database was queried for patients undergoing AWR with CST and contamination. A case control cohort was identified using propensity score matching. Results There were 286 CSTs performed in contaminated cases. After propensity score matching, 61 CSTs were compared to 61 No-CSTs. These groups were matched by defect area (CST:287.1 ± 150.4 vs No-CST:277.6 ± 218.4 cm2, p = 0.156), BMI (32.0 ± 7.0 vs 32.2 ± 6.0 kg/m2, p = 0.767), diabetes (26.2% vs 32.8%, p = 0.427), and panniculectomy (52.5% vs 36.1%, p = 0.068). Groups had similar rates of wound complications (42.6% vs 40.7%, p = 0.829) and recurrence (4.9% vs 13.1%, p = 0.114). Conclusions The use of CST in the face of contamination is not associated with an increase in wound complications, mesh complications, or recurrence.

Over the past several decades, technical advances in breast reconstruction have resulted in the development of flaps that are aimed at progressively decreasing abdominal wall morbidity. There is, however, ongoing controversy related to the superiority of deep inferior epigastric perforator (DIEP) flaps over muscle-sparing TRAM (MS-TRAM) flaps. Hence, the question remains unanswered as to which approach should be considered the standard of care, and more importantly, whether the rate of DIEP flap utilization should be considered a quality metric in breast reconstruction. In this review article, we examine the literature pertaining to abdominal free tissue transfer in breast reconstruction from both donor site and flap characteristics as well as the resultant complications and morbidity. The impact on the donor site remains a prevailing principle for autologous breast reconstruction; thus, must be adequately respected when classifying what is left behind following flap harvest. The most commonly used nomenclature is too simplistic. This, in turn, leads to inadequate incorporation of critical variables, such as degree of muscular preservation, fascial involvement, mesh implantation, and segmental nerve anatomy. Currently, there is insufficient evidence to support DIEP flap harvest as a quality indicator in breast reconstruction, as DIEP flap outcomes are not clearly superior when compared with MS-TRAM flaps.

The closure of wounds associated with soft tissue defects is surgically challenging, frequently requiring extensive plastic surgery and free flaps. The combination of ADM and STSG is an innovative method used to cover such wounds. The human-derived ADMs (H-ADMs) are the most described in the literature but according to European legislations, Companies H-ADMs outside the EC are not allowed to commercialize them in Europe, H-ADMs being “human products” and not “medical devices”, so being ruled by European legislations on transplants. The Skin Bank of the Bufalini Hospital (Cesena, Italy) obtained in 2009 the approval for the production and distribution of the first human cadaver-donor derived ADM from the Italian National Transplant Center and National Health Institute, we called with the Italian acronym M.O.D.A. (Matrice Omologa Dermica Acellulata). We present here the first use of a new H-ADM for treatment of distal lower extremity wounds with exposed tendons managed in one-stage pocedure with STSG. The excellent performance suggests that in cases where autologous tissue is unavailable or undesirable, the use of M.O.D.A. in one-stage procedure represents a promising alternative for covering wounds associated with tendons exposition.

Flap reconstruction is recommended for select patients undergoing abdominoperineal resection to mitigate complications. However, the clinical effectiveness and financial implications of flap reconstruction remain unknown. The authors aim to compare the costs and complications for patients undergoing abdominoperineal resection with and without flap reconstruction.The Truven MarketScan Databases (2009 to 2016) were used to perform retrospective population-based analysis of colorectal carcinoma patients who underwent abdominoperineal resection with and without flap reconstruction. Univariate and multivariable logistic regressions were used to study effective cost (cumulative cost/number of healthy days) and complications.Of 2557 total abdominoperineal resection patients, 194 patients underwent flap reconstruction. Patients undergoing flap reconstruction had a higher Elixhauser Comorbidity Index (p = 0.004) and were more likely to have local invasion (p0.001). At 6 months postoperatively, there were no differences in complications between the two groups (p = 0.116). Flap reconstruction was protective against intraabdominal infections (OR, 0.4; 95 percent CI, 0.2 to 0.9; p = 0.033) but conferred an increased risk of wound complications (OR, 1.5; 95 percent CI, 1.0 to 2.3; p = 0.039). Total median cost of care was similar (abdominoperineal resection alone, $40,050; abdominoperineal resection with flap, $41,380; p = 0.456). Effective cost was greater for abdominoperineal resection alone ($259/healthy day) than abdominoperineal resection with flap ($186/healthy day) but was not statistically significant (p = 0.17).Patients with flap reconstruction displayed a higher comorbidity score and more extensive disease, but these unfavorable factors did not result in a higher complication rate, total cost, or effective cost. Therefore, flap reconstruction for complex perineal defects confers a benefit in select patients and is a judicious use of health care resources.Therapeutic, III.

An ideal scar is flat, thin, and color matched to the surrounding skin. Incision planning, skin closure, and postoperative care are vital to create an inconspicuous scar. Depressed, hypertrophic, and keloid scars each pose unique challenges to the facial plastic surgeon. Several surgical and nonsurgical options exist in the treatment of scars. Appropriate treatment is based on scar location, quality, and size as well as patient history, preferences, and expectations. This article discusses techniques for prevention and treatment options for unsightly and hypertrophic scars.

AIM The efficiency and safety of EZ-close Port-Site Closure System were investigated in comparison with those of the Carter-Thomason CloseSure System (CT) device. METHODS This was a prospective randomized control study. The primary outcome was the time taken to complete the closure of the port site using either the EZ or CT. The suture time (mean±SD) for the EZ group was significantly less than that of the CT group (36.8±10.1 s for the EZ group vs. 48.9±21.5 s for the CT group, P=0.004). There was no need for additional instruments in the EZ group, but in 84.6% of the patients in the CT group, a grasper was required to hold the tie (P

PURPOSE The role of the plastic surgeon in wound management following complications from prior spinal surgeries is well established. The present study evaluates wound complications following plastic surgeon closure of the primary spinal surgery in a large patient population. METHODS Spinal surgeries closed by a single plastic surgeon at a large academic hospital were reviewed. Descriptive statistics were applied and outcomes in this sample were compared with previously published outcomes using 2-sample z tests. RESULTS Nine hundred twenty-eight surgeries were reviewed, of which 782 were included. Seven hundred fifteen operations were for degenerative conditions of the spine, 22 for trauma, 30 for neoplasms, and 14 for congenital conditions. Four hundred twenty-one were lumbosacral procedures (53.8%) and 361 (46.2%) cervical. Fourteen patients (1.8%) required readmission with 30 days. This compares favorably to a pooled analysis of 488049 patients, in which the 30-day readmission rate was found to be 5.5% (z=4.5, P

Large and complex colon polyps are frequently referred to surgery for fear of perforation that may need emergency surgery. During the last 15 years, advances in clip and suturing devices allowed us to close perforations and avoid surgery. In addition, we have made substantial progress in our understanding of the lesions at risk for either immediate or delayed perforation. This article focuses on the colonoscopic closure of resection defects and perforations and the prevention and treatment of colon perforations after endoscopic resection.

Background We aimed to evaluate multiple transit-time flow measurements during coronary artery bypass grafting. Methods Transit-time flow measurements were performed first on the arrested heart both with and without a proximal snare on the target coronary artery, second, after weaning from cardiopulmonary bypass, and third, before chest closure. Results Among the 214 grafts considered, 9 (4.2%) were patent and 6 (2.8%) were failing. In the failed grafts, an abnormal transit-time flow was found during the first measurement, in 5 (2.3%) cases with a proximal snare and in one (0.47%) without a snare. In these cases, technical errors with the distal anastomoses were found and immediately corrected. A problem with the proximal anastomosis was found in one graft during the second measurement and corrected right away. Bending due to excessive length was found in 2 (0.93%) grafts during the third measurement, and graft repositioning was performed. The first transit-time flow measurement showed that mean graft flow was significantly decreased with a proximal snare compared to without a proximal snare, throughout the entire coronary territory. Pulsatility index during the first transit-time flow measurement was higher with a proximal snare than without one. Conclusions The 3-time transit-time flow measurement strategy makes it possible to verify and immediately correct technical problems with coronary bypass grafts.

Median sternotomy remains the most common access to perform cardiac surgery procedures. However, the experience of the operating surgeon remains a crucial factor during sternal closure to avoid potential complications related to poor sternal healing, such as mediastinitis. Considering the lack of major randomized controlled trials and the heterogeneity of the current literature, this narrative review aims to summarize the different techniques and approaches to sternal closure with the aim to investigate their reflections into clinical outcomes and to inform the choice on the most effective closure method after median sternotomy. A literature search through PubMed, Embase, EBSCO, Cochrane database of systematic reviews, and Web of Science from its inception up to April 2019 using the following search keywords in various combinations: sternal, sternotomy, mediastinitis, deep sternal wound infection, cardiac surgery, closure. Single wire fixation methods, at present, seems the most useful method to perform sternal closure in routine patients, although patients with a fragile sternum might benefit more from a figure-of-eight technique. In high-risk patients (e.g. chronic pulmonary disease, obesity, bilateral internal mammary artery harvesting, diabetes, off-midline sternotomy), rigid plate fixation is currently the most effective method, if available; alternatively, weave techniques could be used. The choice among the sternal closure techniques should be mainly inspired and tailored on the patient’s characteristics, and correct judgement and experience play a pivotal role. A decisional algorithm has been proposed as an attempt to overcome the absence of specific guidelines and to guide the operative approach. This operative approach might be used also in non-cardiac procedure in which median sternotomy is required, such as in case of thoracic surgery.

Introduction Implantation rates of cardiac implantable electrophysiological devices (CIEDs) are rising, mainly because of the expansion of implantable cardioverter-defibrillators indications for primary prevention. As the CIED usage increases, CIED-related complications are also in rise. Transvenous approach and laser utilization techniques are replacing the open heart surgeries, for removal of CIED systems that are suspected to be infected. In this study, we aimed to share our new method of fasciocutaneous flap coverage results of patients with exposed CIED systems who were not eligible for the CIED replacement surgery for various reasons. Patients and methods Patients operated with rotational fasciocutaneous flaps with addition of pectoralis fascia, owing to their exposed CIEDs between June 2016 and January 2019, were enlisted. Patients with signs of infection whether systemic or limited to the CIED pocket with or without positive blood cultures were referred to infectious diseases department and not included in this study. Patients included in the study were evaluated retrospectively in terms of demographic data, implanted CIED type, time elapsed from implantation to exposure, from referral to flap coverage operation, total follow-up time, survival ratios during follow-up, and complications related to flap coverage operation. In addition, indications for CIED implantation, patient comorbidities, and culture results obtained from the capsule encompassing the CIED battery unit were included to the evaluation. Results A total of 13 patients with exposed CIEDs have undergone total capsulectomy and CIED system coverage with rotational fasciocutaneous flaps. The mean patient age ± SD was 60.2 ± 13.4 years. The average time elapsed from CIED implantation to exposure was 27.3 ± 15.4 months. The average time spanned from initial referral to operation was 6 ± 1.6 days. The most prevalent comorbidity was diabetes mellitus. The average time elapsed during operation for pectoral fascia incorporated rotation flaps was 90 ± 10.6 minutes. Coagulase negative staphylococci were the dominant species (46.5%) obtained from capsule cultures. Apart from 1 case of hematoma, no early or late operation-related complication was encountered. Conclusions A more precise definition of contamination and infection has to be made in guidelines, which may lead the first group to be treated without extraction. Surgical method defined in this study can be used for the treatment of patients in contaminated CIED subgroup, conserving individuals from risks of device extraction.

Background: Given appropriate case selection and capability, many acute lacerations can be managed in the primary care setting. An understanding of the basic pathophysiology, assessment and management principles is essential. Objective: The aim of this article is to provide a basic framework for assessing and managing simple acute lacerations. Discussion: The aim of assessment is initially to decide whether the laceration is suitable for office-based treatment, and then whether it requires formal surgical closure with sutures or staples. Two non-surgical techniques for skin closure in amenable wounds are described. A companion article in this issue provides details of surgical closure techniques and wound aftercare.

Wound healing is a series of different dynamic and complex phenomena. Many studies have been carried out based on the type and severity of wounds. However, to recover wounds faster there are no suitable drugs available, which are highly stable, less expensive as well as has no side effects. Nanomaterials have been proven to be the most promising agent for faster wound healing among all the other wound healing materials. This review briefly discusses the recent developments of wound healing by nanotechnology, their applicability and advantages. Nanomaterials have unique physicochemical, optical, and biological properties. Some of them can be directly applied for wound healing or some of them can be incorporated into scaffolds to create hydrogel matrix or nanocomposites, which promote wound healing through their antimicrobial, as well as selective anti- and pro-inflammatory, and proangiogenic properties. Owing to their high surface area to volume ratio, nanomaterials have not only been used for drug delivery vectors but also can affect wound healing by influencing collagen deposition and realignment and provide approaches for skin tissue regeneration.

Background: Delayed sternal closure commonly is used after pediatric cardiac surgery. Its benefits include relieving cardiac compression and stabilizing postoperative critically ill patients. Methods: We retrospectively reviewed the records of 72 patients, who had undergone delayed sternal closure, among 1,254 patients operated for congenital heart diseases. Indications of delayed sternal closure, perioperative hemodynamic and metabolic status, postoperative infection, and mortality were reported. Results: Transposition of great arteries was the most common preoperative cardiac pathology (26.3%). Bleeding and hemodynamic instability were the most frequent indications for delayed sternal closure, representing 38.8% and 34.7%, respectively. The mean duration of open chest was 3.45 days ± 1.46 days. The mean duration of ICU stay was 20.95 days ± 20.06 days. Two patients had deep sternal wound infection. Sepsis was found in 39 patients (54.1%), and the most common causative organism was coagulase negative (30.5%). ICU stay was a significant risk factor for sepsis (P = .003); duration of open sternum, period of mechanical ventilation (MV), and total hospital stay were not statistically significant risk factors. Sternal closure time (SCT) was affected by period of hemodynamic instability (P = .036). Bypass time, clamping time, and nonsurgical bleeding did not significantly affect SCT. The mortality rate was 15.2% (N = 11). Conclusion: Delayed sternal closure is a simple and effective technique that could prevent postoperative cardiac compression in hemodynamic instability states after pediatric cardiac operations.

Objectives Cosmesis after surgical wound closure is an important outcome. This is relevant after thyroid and parathyroid surgery as anterior neck scars are visible and often of concern to patients. We aimed to investigate whether wound closure method influences cosmetic outcome in thyroid and parathyroid surgery, in particular using sutures, staples, steri-strips and glue. Design We performed a systematic review of MEDLINE, PubMed, EMBASE, CINAHL and Cochrane focusing on wound cosmesis following thyroid and parathyroid surgery. Searches were conducted using combinations of the search terms: thyroid/parathyroid surgery, wound/skin closure and suture, staples, clips, glue and steri-strips, using appropriate MESH terms and Boolean operators. Main outcome measures Primary outcome was wound cosmesis. Secondary measures were also extracted. Results Initial search found 304 papers and after systematic review, a total of 10 studies compared different closure methods and cosmetic outcomes. There were nine randomised controlled trials and one cohort study, with a total of 712 patients. Three studies compared staples vs glue; three compared sutures vs clips; two compared suture vs steri-strips and two studies for suture vs glue. In general, short-term cosmesis was better with subcuticular sutures compared to glue or clips, long-term cosmetic outcomes were not influenced by closure method. Conclusions We found closure with subcuticular suture or steri-strips produced superior short-term cosmetic outcomes. Although long-term cosmetic outcome is not influenced by closure method, given the superior cosmetic outcome and advantage of not needing removal, we recommend subcuticular sutures should be performed for wound closure in thyroid and parathyroid surgery.

Introduction. Closing the wound cavity after the coccyx resection in patients with posttraumatic coccygodynia remains an issue unresolved. Closing the wound cavity with local tissues often leads to the wound dehiscence due to excessive tension which in turn leads to suppuration and prolonged healing.This paper aims to assess experimentally the effectiveness of using ground autograft bone of the coccyx removed for the closure of the surgical wound.Materials and methods. In the animal experiment the coccyx resection was performed under a combined anaesthesia in six pigs (three in the study group and three in control). In the control group the wound edges were sutured to its floor. In the study group after the coccyx resection the ground bone mass made of the coccyx resected was implanted into the wound cavity.Results and discussion. In the control group the wound dehiscence was registered in all the animals. After the animals were taken out of the experiment it was established that in the study group a new consolidated bony conglomerate was formed without any pronounced inflammatory changes around the wound. In control the wound cavity healed with secondary intention.Conclusions. The study confirms the effectiveness of using ground autograft bone for the closure of the wound cavity.

Summary: Background/Objective: Biliary leakage is a potential complication of liver resection and is still a concern. The aim of the present study was to evaluate the effectiveness of four routinely used sealants in preventing bile leakage under pressure from an induced perforation of the gallbladder in a porcine model. Methods: Forty Landrace pigs were randomly assigned to one of five groups. These included a control group (n = 8) and one group each for the sealants TachoSil®, TissuCol Duo®, Coseal®, and FloSeal® (n = 8 per group). In the control group, the perforation was left unsealed. To evaluate the biliostatic potential of the sealants, we measured the pressure that was needed to induce leakage (mmHg) and the gallbladder volume (cc) at the time of leakage in each group. Results: A significantly higher mean pressure was required to induce leakage in the sealant groups compared with the control group. However, the biliostatic effects were heterogeneous among the sealant groups. Sealants with the highest to lowest effectiveness were TachoSil, Coseal, TissuCol, and FloSeal. The mean gallbladder volume at the time of leakage also varied between sealant groups. Conclusion: Biliostatic properties are markedly improved by the use of modern sealants compared with using no sealant. However, the advantages and disadvantages of using sealants should be carefully considered in each clinical situation. The effectiveness of the sealants should be evaluated in chronic and clinical studies. Keywords: Bile leakage, Gallbladder, Sealant, Swine

Background Mesh suture used in high-tension wound closures produces large knots susceptible to increased palpability, infection, and foreign body response; yet has superior tensile strength and increased resistance to cutting through tissue compared to standard suture. This study investigates mesh suture fixation in abdominal tissue with a knotless novel, low-profile anchor-clip. Methods Single and double end fixation of mesh suture in swine rectus abdominus fascia with an anchor-clip, a knot, and predicate device fixation underwent cyclic testing followed by pull-to-failure testing. Results Failure load of standard knot, single corkscrew and double anchor-clip were not statistically different, but were significantly greater than single anchor-clip and double corkscrew fixation (p > 0.05). Conclusions The anchor-clip is ∼60% smaller than a standard knot while maintaining fixation strength when exposed to physiologic forces using double anchor-clip fixation in abdominal wall closure.

Background An open abdomen is often necessary for survival of patients after peritonitis, compartment syndrome, or in damage control surgery. However, abdominal wall retraction relieves delays and complicates abdominal wall closure. The principle of the newly fascia preserving device (FPD) is the application of anteriorly directed traction on both fascial edges over an external support through a longitudinal beam to relieve increased abdominal pressure and prevent fascial retraction. Methods Twelve pigs were randomly divided into two groups. Both groups underwent midline laparotomy under general anesthesia. Group one was treated with the new device, group two served as controls. The tension for closing the abdominal fascia was measured immediately after laparotomy as well as at 24 and 48 h. Vital parameters and ventilation pressure were recorded. Post mortem, all fascial tissues were histologically examined. Results All pigs demonstrated increases in abdominal circumference. In both groups, forces for closing the abdomen increased over the observation period. Concerning the central closing force after 24 h we saw a significant lower force in the FPD group (14.4 ± 3 N) vs. control group (21.6 ± 5.7 N, p

The paper examines the development and testing of an electro-pneumatic device for wound healing therapy after surgery in the neck area. The device generates air pressure values in a miniaturized cuff using electronic circuitry to drive an electro-valve and air compressor. The device works in two distinct modes: continuous pressure mode and pulsating pressure mode. The pressure value setting can vary from 3 to 11 mmHg, and the pulsating pressure mode’s operating frequency range is approximately 0.1 to 0.3 Hz. Laboratory measurements were conducted to evaluate the device’s correct functioning in both continuous and pulsating pressure modes. A four-day prospective study with animals (n = 10) was also conducted to evaluate neck wound healing therapy using the electro-pneumatic device. Out of the twelve histological parameters analysed to reveal the differences between the experimental and control wounds, only one demonstrated a significant difference. Out of the ten animals treated with the device, three showed a significant difference in terms of benefit after therapy. We can therefore conclude that the device potentially improves the wound healing process in the neck area if the pre-set air pressure value does not exceed 8 mmHg.

Background Many techniques have been described to correct prominent ears, including cartilage-suturing, cartilage-scoring, and cartilage-breaking techniques. Understanding the topography and anatomy of the auricular cartilage is crucial for performing safe otoplasty with consistent results. Methods Two hundred consecutive patients with prominent ears were operated on using a modified Mustarde and Furnas technique with some refinements and without performing any cartilage scoring or excision. Adequate dissection and exposure of cartilage and precise repositioning of the tail of helix (cauda helicis) are keys to correction of lobule prominence without the need for any adjunctive procedures such as skin excision from the back of the lobule or suture fixation of the lobular tissues to the concha, mastoid, or scalp. Detailed description of the technique and review of the complications are presented. Results This suturing-only technique had a low complication rate. Hematoma occurred in two patients only. Skin necrosis and wound dehiscence were not reported in any patient. Suture extrusion was the most common complication and was easily managed, mostly in the clinic. Relapse of deformity needing surgical correction occurred in eight cases. Conclusions The series demonstrates that most of the potential complications of otoplasty can be avoided and favorable results can be obtained by paying attention to the anatomical details of the deformity and the auricular cartilage anatomy. The described cartilage-sparing otoplasty procedure with the refinements outlined resulted in a reproducible natural correction, with a low risk profile, that can be applied to almost all prominent ears.

Background:Delayed sternal closure (DSC) following pediatric cardiac surgery is commonly implemented at many centers. Infectious complications occur in 18.7% of these patients based on recent multicenter data. We aimed to describe our experience with DSC, hypothesizing that our practices surrounding the implementation and maintenance of the open sternum during DSC minimize the risk of infectious complications.Methods:We reviewed patients less than 365 days who underwent DSC between 2012 and 2016 at our institution. Infectious complications as defined by the Society of Thoracic Surgeons Congenital Heart Surgery Database were recorded. Patients with and without infectious complications were compared using Wilcoxon rank sum tests or Fisher exact tests as appropriate.Results:We identified 165 patients less than 365 days old who underwent DSC, 135 (82%) of whom had their skin closed over their open sternum. Median duration of open sternum was 3 days (range: 1-32 days). Infectious complications occurred in 15 (9.1%) patients—13 developed clinical sepsis with positive blood cultures, one patient developed ventilator-associated pneumonia, and one patient developed wound infection (0.6%). No cases of mediastinitis occurred. No statistical differences in characteristics between patients with and without infectious complications could be identified.Conclusion:Infectious complications after DSC at our institution were notably less than reported in recent literature, primarily due to minimization of surgical site infections. Practices described in the article, including closing skin over the open sternum whenever possible, could potentially aid other institutions aiming to reduce infectious complications associated with DSC.

Small steps wound closure of midline laparotomy has been reported to decrease the incidence of incisional hernia development in two randomized controlled trials. The aim of the present study was to evaluate the effect of implementing the small steps wound closure technique in clinical practice with regards to the development of incisional ventral hernia (IVH) and surgical site infections (SSI) in clinical practice. Implementation of the small steps wound closure technique using the small tissue bites technique as the standard closure technique for abdominal midline incisions in our clinical practice was done in March 2015. For this study, all patients from June 2013 until June 2016 with a midline laparotomy, either long or small in case of specimen extraction in laparoscopic surgery, in either elective or emergency setting were included. Conventional large bite wound closure was compared to small steps wound closure with regards to the development of SSI, IVH as well as burst abdomen. A total of 327 patients were included. The small steps suture technique was used in 136 (42%) of the patients, whereas the conventional large bites suture technique was used in 191 patients (58%). A total of 54 patients in the large bites group developed SSI (28%) compared to 23 (17%) patients in the small steps group (p = 0.02). A total number of 10 patients (7%) developed IVH in the small steps group compared to 27 patients (14%) in the large bites group (p = 0.08). Implementation of small bites wound closure of abdominal midline incisions in clinical practice was correlated with a reduction in surgical site infections.

Background This study sought to identify risk factors associated with wound disruption following Caesarean section (CS) in women with class III obesity and to determine the value of individualized perioperative care plans in reducing its incidence. Methods The study included women with class III obesity who underwent CS after 24 weeks of gestation at Mount Sinai Hospital, Toronto, Ontario between 2011 and 2015 and collected data on demographics, clinical history, and perioperative details. Multivariable logistic regression analysis was performed to identify factors likely to contribute to a higher incidence of wound disruption (level of evidence II-3B). Results Of the 334 identified cases, in women with a mean BMI of 48.20 ± 7.52 kg/m2, there were 60 cases of wound disruption (18%). The most common perioperative interventions involved Pfannenstiel skin incisions (75.6%), subcutaneous tissue closure (65.4%), use of pressure dressings (65%), and thromboprophylaxis (71.8%). On bivariable analysis, surgical time >1 hour (24.2% vs. 13.5%; OR 2.03; P = 0.017) and the use of thromboprophylaxis (20.1% vs. 10.6%; OR 2.22, P = 0.031) were associated with increased wound disruption, but these associations were attenuated on multivariable regression analysis. Conclusions No single risk factor or perioperative intervention was independently associated with wound disruption. However, the use of individualized perioperative care plans resulted in fewer wound disruptions in our cohort when compared with published literature.

Summary Background The vertical rectus abdominis myocutaneous (VRAM) and transverse rectus abdominis myocutaneous (TRAM) flaps have traditionally been excluded from consideration of reconstructions with functional potential, because of their segmental innervation. We present a case series that aimed to demonstrate that segmental innervation does not preclude successful neural anastomoses and can deliver a functional reconstruction of a total compartment in the anterior thigh. Methods This review included all patients who required total anterior thigh compartmentectomy and reconstruction between December 2009 and February 2016 were included from the first author's prospective database. Results Eleven cases were identified, with innervated rectus abdominis flaps used for anterior thigh reconstruction. During the median follow up period of 12 months, all patients had reinnervation of the rectus with six reaching M5, one M4+, one M4, two M3 and one M2, according to Medical Research Council power grades. Conclusion All patients had successful functional reconstruction in the thigh using the rectus abdominis myocutaneous flap.

Abdominal wall transplantation has been consolidated as an alternative to primary abdominal wall closure in intestinal and multiple organ transplant recipients. Given that it is feasible to obtain the visceral graft and the abdominal wall graft from the same donor, abdominal wall transplantation could offer satisfactory outcomes and be easily coordinated. Non-vascularized fascia is one of the alternatives for abdominal wall closure in transplantation. We report two cases of non-vascularized fascia transplantation in intestinal and multivisceral transplants, respectively. Both donors were young (23 and 18 years old). Both recipients had endured multiple previous surgeries, and no surgical alternatives for primary wall repair could be offered. In both cases, a complete abdominal wall flap was retrieved from the donor, however, due to the characteristics of the recipient's abdominal wall defect, only non-vascularized fascia was used after removing skin and subcutaneous cellular tissue from the graft. Abdominal wall transplantation is an option to consider for abdominal wall closure in patients with multiple previous surgeries and no alternatives for primary wall repair.

Summary: Objectives: Monofilament sutures, both absorbable and non-absorbable, have been used for wound closure. Tissue adhesive has been used in closure of clean, low tension wounds. However, there have been very few published studies on the aesthetic outcomes in neck surgeries. The aim of this study is to compare the patients' and doctors’ satisfaction scores in the aesthetic outcome between both methods of closure of thyroidectomy wounds using validated scoring systems. Methods: A double-blinded randomised controlled trial comparing the aesthetic outcome between tissue adhesive and conventional suture was conducted among patients undergoing thyroid and parathyroid surgeries. Ninety-six patients were randomised into two treatment groups. Patients' wounds were scored by an independent observer using the SBSES score at 6 weeks postoperatively and observer component of the POSAS score at 3 months. Results: Forty-nine patients were randomised to the tissue adhesive group while forty-seven patients received the conventional method. There was no statistical difference in the aesthetic outcome using the patient's scoring system between both arms, with a median score of 9 (p = 0.25, SD ± 6.5). The observer's satisfaction score using POSAS was also not statistically significant (median score of 14 (p = 0.77, SD ± 6.2)). No significance was found in the observer's median score using the SBSES scoring system either (score 3, p = 0.12, SD ± 1.3). However, there was significant reduction in the duration of closure using glue (4.42 mins vs 6.36 mins, p

Background and AimsEndo-sponge [Braun Medical] assisted early surgical closure [ESC] is an effective treatment to control pelvic sepsis after ileal pouch-anal anastomosis [IPAA] leakage, and became standard treatment in our centre from 2010 onwards. The aim of this cohort study was to assess the long-term pouch function of ulcerative colitis [UC] patients treated with ESC or conventional management [CM] for anastomotic leakage after IPAA.MethodsConsecutive patients who underwent an IPAA for UC between 2002 and 2017 were included. Patients treated with ESC [2010–2017] or CM [2002–2009] for anastomotic leakage were compared with control patients without anastomotic leakage of the corresponding time period. Main endpoints were long-term pouch function on a 3-point scale and pouch failure, as measured with the validated pouch dysfunction score questionnaire.ResultsSome 280 of 334 patients [84%] returned the pouch dysfunction questionnaire, of whom 18 were treated with ESC and 22 with CM for anastomotic leakage. Control cohorts included 133 [2010–2017] and 107 patients [2002–2009]. Between ESC-treated patients and control patients, pouch function [p = 0.647] and pouch failure rates [0/18 versus 5/133, p >0.99] were similar. CM resulted in worse pouch function [p = 0.016] and a higher pouch failure rate [5/22 versus 5/107, p = 0.013] compared with control patients.ConclusionsESC, in contrast to CM, for IPAA leakage in UC patients is associated with preservation of pouch function and preclusion of pouch failure, probably due to early and effective treatment of pelvic sepsis.

Background Traditionally, a 30-day postoperative period is used to assess outcomes in surgery. However, it is not clear if this is sufficient. Our study assessed readmissions and their risk factors following the surgical repair of pressure ulcers in a 90-day postoperative period. Methods Patients with a pressure ulcer to the lower back, hip, and/or buttocks who underwent a pedicled or flap based wound operation were identified in the National Readmissions Database. We then analyzed risk factors for overall 0–90-day readmissions, early readmissions (0–30 days), and late-readmissions (31–90 days). Results 3329 patients were identified, of which 154 (4.66%) had surgical wound-related readmissions. A majority of these occurred after 30 days (53.89%). 90% of patients with a surgical-wound related readmission were readmitted within 63 days of index procedure. Conclusions The traditional 30-day outcome period is not enough to properly assess outcomes in pressure ulcer surgery such as readmission. We demonstrate that a period of at least 10 weeks and perhaps the entire global 90-day postoperative period would be more appropriate to evaluate readmissions after ulcer repair.

Wound leakage has been shown to increase the risk of prosthetic joint infections (PJIs) in primary total hip (THA) and knee arthroplasty (unicondylar and total knee arthroplasty; KA). The aim of this study is to determine whether the addition of a continuous subcuticular bonding stitch to a conventional three-layer closure method reduces the incidence of prolonged wound leakage and PJIs after THA and KA. This retrospective cohort study included all patients receiving a THA or KA. Patients in the control group with a three-layer closure method had surgery between November 1st 2015 and October 31st 2016, and were compared to the study group with a four-layer closure method that had surgery between January 1st 2017 and December 31st 2018. The primary outcome was incidence of prolonged wound leakage longer than 72 h. Differences were evaluated using logistic regression. Incidence of PJIs was the secondary outcome. A total of 439 THA and 339 KA in the control group and 460 THA and 350 KA in the study group were included. In the control group, 11.7% of the patients had a prolonged leaking wound compared to 1.9% in the study group (p

Objectives Surgical adhesives are increasingly used for vocal fold microsurgery to assist wound closure and reduce the risks of scar formation. Currently used vocal fold adhesives such as fibrin glue, however, have thus far not been found to promote wound closure or reduce scarring. The objectives of this study were to investigate the mechanical strength and the cytotoxicity of three commercially available adhesives (Glubran 2, GEM, Viareggio, Italy; BioGlue, CryoLife, Kennesaw, GA; and Tisseel, Baxter Healthcare, Deerfield, IL) for vocal fold wound closure. Methods Shear and tension tests were performed on 150 porcine larynges. The cytotoxicity of the adhesives to immortalized human vocal fold fibroblasts was investigated using neutral red uptake assays. Results The average shear adhesive strength for Tisseel, BioGlue, and Glubran 2 was 13.86 ± 5.03 kilopascal (kPa), 40.92 ± 17.94 kPa, and 68.79 ± 13.29 kPa, respectively. The tensile adhesive strength for Tisseel, BioGlue, and Glubran 2 was 10.70 ± 6.42 kPa, 34.27 ± 12.59 kPa, and 46.67 ± 12.13 kPa, respectively. The vocal fold cell viabilities in extracts of Tisseel, BioGlue, and Glubran 2 were 99.27%, 43.05%, and 1.79%, respectively. Conclusion There was a clear tradeoff between adhesive strength and toxicity. The maximum failure strength in shear or tension of the three surgical adhesives ranked from strongest to the weakest was: 1) Glubran 2, 2) BioGlue, and 3) Tisseel. Tisseel was found to be the least toxic of the three adhesives, whereas Glubran 2 was the most toxic. Level of evidence NA Laryngoscope, 129:2139-2146, 2019.

Background This study compared the safety and effectiveness of intraoperative device closure of a perimembranous ventricular septal defect (pmVSD) using the right thoracic minimal incision to right ventricle and lower midline sternotomy to right ventricle approaches. Methods We retrospectively analyzed the clinical data of 46 patients who underwent intraoperative device closure of a pmVSD through the right thoracic minimal incision to right ventricle route (group 1) and 52 patients who underwent intraoperative device closure of a pmVSD through a minimal incision in the lower sternum (group 2) at our hospital from March 2016 to March 2017. In group 1, a right thoracic minimal incision to the fourth intercostal space was used to establish a delivery system through the right ventricle to complete pmVSD closure. Results In group 1, intraoperative device closure of the pmVSD was successful in 44 patients and was converted to open surgery in 2 patients (a delivery system could not be established in the one, and a significant residual shunt was present in the other). In group 2, the corresponding numbers of patients were 50 and 2, respectively. Neither group exhibited serious adverse effects, including dislocation of the occluder, third-degree atrioventricular block, or new onset of aortic valve regurgitation during the perioperative period or during a median follow-up period of 1 to 2 years. Conclusions Intraoperative device closure of a pmVSD through the right thoracic minimal incision to right ventricle approach is safe and effective. This procedure can avoid some of the shortcomings caused by sternotomy, uses an incision with an improved cosmetic appearance, and is worth recommendation.

Introduction Diverting stomata are recommended in patients with low anterior resection and risk factors in order to reduce the severity of anastomotic leaks. Usually, a radiology study is performed prior to the closure of the stoma to detect subclinical leaks. The aim of the present study is to assess the clinical utility of the radiology study. Methods A prospective cohort study of patients undergoing anterior rectal resection for rectal cancer and those who underwent stoma closure without contrast enema. This study was carried out after a retrospective review of radiology study results prior to the closure of the stoma in patients operated from 2007 to 2011. Results Eighty-six patients met the study criteria. Thirteen patients (15.1%) presented pelvic sepsis. Contrast enema before stoma closure was pathological in 8 patients (9.3%). Five out of the 13 patients with pelvic sepsis had a pathological radiological study, compared to only 3 out of the 73 patients without intra-abdominal complications after rectal resection (38.5% vs 4.1%; P=.001). Based on these results, we conducted a prospective study omitting the contrast enema in patients with no postoperative complications. Thirty-eight patients had their stoma closed without a prior radiology study. None of the patients presented pelvic sepsis. Conclusions Radiology studies of the colorectal anastomosis before reconstruction can safely be omitted in patients without pelvic sepsis after the previous rectal resection.

The purpose of this study was to determine the impact of the incision used for specimen extraction on wound infection during laparoscopic colorectal surgery.All patients undergoing elective laparoscopic colorectal resection in a single specialized department from 2000 to 2011 were identified from a prospectively maintained institutional database. Specific extraction-sites and other relevant factors associated with wound infection rates were evaluated with univariate and multivariate analyses.2801 patients underwent specimen extraction through infra-umbilical midline (N = 657), RLQ/LLQ (N = 388), stoma site (N = 58), periumbilical midline (N = 629), Pfannenstiel (N = 789) and converted midline (N = 280). The overall wound infection rate was 10% and was highest in converted midline (14.6%) and Pfannenstiel (11.4%) incisions, while the lowest rate was associated with RLQ/LLQ (N = 13, 3.3%). Independent factors associated with wound infection were increased BMI (p 0.001), extraction site location (p = 0.006), surgical procedure (p = 0.020, particularly left-sided colectomy and total proctocolectomy), diagnosis (p 0.001, particularly sigmoid diverticulitis and inflammatory bowel disease), intraabdominal adhesions (p = 0.033) and intrabdominal rather than pelvic procedure (p = 0.005).A RLQ/LLQ extraction site is associated with the most reduced risk of wound infection in laparoscopic colorectal surgery.
