Comparing wound complication rates following closure of hip wounds with metallic skin staples or subcuticular vicryl suture: a prospective randomised trial

Superiority trial for the development of an ideal method for the closure of midline abdominal wall incisions to reduce the incidence of wound complications after elective gastroenterological surgery: study protocol for a randomized controlled trial

BACKGROUND

The recent guidelines from the European and American Hernia Societies recommend a continuous small-bite suturing technique with slowly absorbable sutures for fascial closure of midline abdominal wall incisions to reduce the incidence of wound complications, especially for incisional hernia. However, this is based on low-certainty evidence. We could not find any recommendations for skin closure. The wound closure technique is an important determinant of the risk of wound complications, and a comprehensive approach to prevent wound complications should be developed.

METHODS

We propose a single-institute, prospective, randomized, blinded-endpoint trial to assess the superiority of the combination of continuous suturing of the fascia without peritoneal closure and continuous suturing of the subcuticular tissue (study group) over that of interrupted suturing of the fascia together with the peritoneum and interrupted suturing of the subcuticular tissue (control group) for reducing the incidence of midline abdominal wall incision wound complications after elective gastroenterological surgery with a clean-contaminated wound. Permuted-block randomization with an allocation ratio of 1:1 and blocking will be used. We hypothesize that the study group will show a 50% reduction in the incidence of wound complications. The target number of cases is set at 284. The primary outcome is the incidence of wound complications, including incisional surgical site infection, hemorrhage, seroma, wound dehiscence within 30 days after surgery, and incisional hernia at approximately 1 year after surgery.

DISCUSSION

This trial will provide initial evidence on the ideal combination of fascial and skin closure for midline abdominal wall incision to reduce the incidence of overall postoperative wound complications after gastroenterological surgery with a clean-contaminated wound. This trial is expected to generate high-quality evidence that supports the current guidelines for the closure of abdominal wall incisions from the European and American Hernia Societies and to contribute to their next updates.

Effect of suture closure and staple closure on postoperative wound complications in patients undergoing knee replacement surgery: A meta-analysis

The purpose of this meta-analysis is to determine if the application of stitching in the closed area of the knee arthroplasty remains significantly superior to that of the staples. Data sources: EMBASE, Cochrane Libraryand, publications, and the Web of Science. Patients were treated with staples for closure of their wounds, or with conventional stitches for closure of wounds. The main findings were surgical site infection, wound dehiscence, and cutting time. The secondary results were the time to completion, the duration of the hospitalization, and the time to discharge. We incorporated the SIX trial into the meta-analyses with Review Manager V.5.3. The hazard ratio was computed as a therapeutic outcome with respect to the heterogeneity. For more than 50% of heterogeneous samples, we employed a stochastic effect model. The results showed that there was no significant difference in the degree of infection, the degree of dehiscence, the length of the cut and the degree of satisfaction of the wound. But the time to close the wound and the time to operate were significantly different. The time needed to close the wound was shorter than that of the suture (OR, -227. 22; 95% CI, -238. 74, -215. 69 p < 0. 0001); The time taken to replace the knee was also significantly lower among those who had been stapled sutures (OR, -5.46; 95% CI, -10. 43, -0.49 p = 0. 03). Wound closing materials are an afterthought for many orthopaedic surgeons. Together, the findings from a number of comparative studies indicate that the selection of wound closure materials might affect the outcome of the surgery. The evidence, however, is weak because of the heterogeneous approach adopted in earlier research. This study program is intended to provide guidance on how to select the best wound closure material for the purpose of identifying if there is any difference in the incidence of injuries among traditional stitches and staples.

Skin Reactions Following Primary Total Knee Arthroplasty With an Adhesive Superficial Closure System: A Case Series

BACKGROUND

We investigated a skin adhesive closure device consisting of a self-adhesive polyester mesh placed over the surgical incision, followed by a liquid adhesive that is spread over the mesh and surrounding the skin. It is intended to reduce wound closure times, scarring, and skin complications associated with traditional closure with sutures or staples. The aim of this study was to report on skin reactions in patients who underwent primary total knee arthroplasty (TKA) using the skin adhesive closure system.

METHODS

A retrospective review of patients who underwent TKA using adhesive closure between 2016 to 2021 at a single institute was performed. A total of 1,719 cases were analyzed. Patient demographics were collected. The primary outcome was any postoperative skin reaction. Skin reactions were classified as allergic dermatitis, cellulitis, or other. Treatment(s), duration of symptoms, and surgical infections were also collected.

RESULTS

A total of 5.0% (86) of patients were found to have any type of skin reaction following their TKA. Of these 86, 39 (2.3%) had symptoms of allergic dermatitis (AD), 23 (1.3%) had symptoms of cellulitis, and 24 (1.4%) had other symptoms. A total of 27 (69%) allergic dermatitis patients were treated with a topical corticosteroid cream only; their symptoms resolved within an average of 25 days. There was only 1 case of superficial infection (<0.001%). No prosthetic joint infections were observed.

CONCLUSION

Despite skin reactions appearing in 5.0% of cases, the rate of infection was low. A patient-specific preoperative workup and effective treatment strategies can minimize complications associated with adhesive closure system and increase patient satisfaction following TKA.

Occlusive wound closure prevents prolonged wound discharge-A randomised controlled trial in patients undergoing tumour resection and endoprosthetic reconstruction of the proximal femur because of metastatic bone disease

Prolonged wound discharge is a common postoperative complication of orthopaedic procedures and a risk factor for implant-related infection. Occlusive wound closure methods have previously been suggested to reduce or even prevent this complication. We performed a randomised controlled trial on 70 patients who underwent surgical treatment for metastatic bone disease involving the proximal femur at our centre between January 2017 and August 2018. At conclusion of the tumour resection and endoprosthetic reconstruction procedure, patients were randomised to either occlusive wound closure (n = 35), using the Dermabond Prineo-22 skin closure system, or routine wound closure with conventional skin staples (n = 35). Skin closure with occlusive wound closure resulted in a lesser degree (P < .0001) and shorter duration of postoperative wound discharge (HR 2.89 [95% CI 1.6-5.05], P < .0018). Compared with staples, surgical wounds were already dry after a mean of 3.5 days [95% CI 3.2-3.9] versus 6.1 days [95% CI 4.8-7.3] (P < .0001). Prolonged wound discharge for 7 days or more was observed in 23% of patients (n = 8) in the Staples-group but was entirely absent in the occlusive wound closure group (P < .003). This study provides strong evidence that occlusive wound closure reduces frequency, degree, and duration of wound discharge in a patient population at particularly high risk for this complication.

The Routine Use of Running Subcuticular Closures in Orthopaedic Trauma Patients Does Not Increase Wound Complications

OBJECTIVE

To investigate whether the routine use of running subcuticular closures (RSC) in orthopaedic trauma patients increases the rate of wound complications and reoperations.

DESIGN

Retrospective comparative study.

SETTING

Urban Level 1 trauma center.

PATIENTS/PARTICIPANTS

Two hundred sixty-six patients undergoing orthopaedic trauma procedures between June 2020 and March 2022.

INTERVENTION

Adoption of an RSC protocol where any incision/wound that could be approximated with interrupted subcuticular 2-0 monofilament sutures was closed with a running subcuticular 3-0 monofilament suture.

MAIN OUTCOME MEASUREMENTS

Wound complications and subsequent reoperations.

RESULTS

With adoption of the RSC protocol, 91.0% of all orthopaedic trauma procedures were closed with RSC compared with 7.5% of the historical control group. There were no observed differences in the rate of wound complications (proportional difference (PD) 6.0%, confidence interval (CI) -2.3% to 14.1%; P = 0.15) or reoperations (PD 5.2%, CI -1.9% to 12.2%; P = 0.14) between the RSC and the control group. Wound complications were not associated with RSC on univariate analysis (PD 7.2%, CI -10.0% to 24.0%; P = 0.41). On multivariate analysis, an ASA>2 (odds ratio (OR) 2.4, CI 1.0 to 5.7; P = 0.03), lower extremity injuries (OR 4.9, CI 1.3 to 17.8; P = 0.01), and open reduction internal fixation procedures (OR 2.8, CI 1.1 to 7.2; P = 0.02) were found to be independently associated with wound complications.

CONCLUSION

RSC for orthopaedic trauma procedures was not associated with increased wound complications when compared a historical cohort.

Staples versus sutures wound closure in hip and knee arthroplasty: a prospective cohort study

OBJECTIVE

This study aimed to compare two methods of wound skin closure-staples versus vertical mattress nylon sutures-in patients undergoing primary total hip (THR) and total knee replacements (TKR). The comparison was for wound complications as a primary outcome, and satisfaction of patient and nurse as secondary outcomes.

METHOD

A prospective cohort study was conducted at an academic teaching hospital. All the patients who were admitted for either primary THR or TKR from September 2018 to September 2019 were included. Revision surgeries, patients >85 years of age, and those who were on steroid therapy were excluded. Patients were divided into two groups (staples and sutures) to compare the two methods of wound closure. Patients in each group were assessed for characteristics such as age, sex, weight, height, comorbidities, smoking status, postoperative wound complications, reoperation and patient/nurse satisfaction.

RESULTS

A total of 100 patients met the inclusion criteria. In the staples group (n=50), 26 patients underwent THR while 24 patients underwent TKR. In the sutures group (n=50), 23 patients underwent THR and 27 patients underwent TKR. Overall, there was no significant difference between the two groups (staples versus sutures) in terms of wound complications (p=0.401), patient satisfaction (p=0.357) and nurse satisfaction (p=0.513). Further analysis compared THR and TKR subgroups (THR staples versus THR sutures and TKR staples versus TKR sutures). The results showed no significant difference between the staples and sutures subgroups of THR and TKR in terms of wound complications, patient satisfaction and nurse satisfaction.

CONCLUSION

In THR and TKR, there was no significant difference between either vertical mattress nylon sutures or staples primary skin closure in terms of wound complications and patient satisfaction in this study. The decision on wound closure method should be based on the availability of resources in the institution/country.

Advantages of skin closure with subcuticular suture for liver resection on postoperative and cosmetic outcomes: a propensity matched analysis

PURPOSE

The effects of subcuticular sutures on postoperative and cosmetic outcomes in patients who underwent liver resection have not been well studied. Here, we investigated the advantages of subcuticular suture compared to skin stapler regarding open liver resection.

METHODS

We assessed 342 patients who underwent liver resection at Nara Medical University between 2008 and 2015. They were divided into two groups: subcuticular suture and staple groups. Baseline characteristics and perioperative outcomes were retrospectively compared using one-to-one propensity score matching analysis.

RESULTS

In this period, 179 patients underwent skin closure with subcuticular sutures and 163 patients underwent skin closure with staples. After propensity matching, 85 pairs of cases were matched. The incidence of wound infection was similar in the two groups (3.5% in the subcuticular suture group and 9.4% in the staple group; p = 0.119). The length of hospital stay was significantly shorter in the subcuticular suture group than in the staple group (10 days vs 15 days; p < 0.001). In addition, the rate of patients who were discharged within 7 days after surgery was statistically higher in the subcuticular group (21.1% vs 3.5%, p = 0.001). Hypertrophic scar 6 months after surgery was significantly less frequent in the subcuticular group (9.4% vs 25.9%, p = 0.010).

CONCLUSION

Subcuticular sutures might be advantageous for liver surgery reducing length of hospital stay and proportion of hypertrophic scar.

Staples versus sutures for skin closure in hip arthroplasty: a meta-analysis and systematic review

Objective

The purpose of the present study was to estimate complications and other outcomes associated with staple and suture closure after hip arthroplasty through meta-analysis techniques and a systematic review.

Methods

We searched for articles in EMBASE, PubMed, Medline, Web of Science and the Cochrane Library. To determine the eligibility of the searched trials, Cochrane Collaboration's Review Manager software was used to perform the meta-analysis.

Results

Five randomized controlled trials and one retrospective cohort trial were included in our study. Our study indicated that for skin closure after hip arthroplasty, the risks of superficial infection and prolonged discharge were higher with staples than with sutures. There was no significant difference between the two groups in terms of allergic reaction, dehiscence, inflammation, abscess formation, the Hollander Wound Evaluation Scale or patient's satisfaction with skin closure methods. However, suturing required a longer operating time.

Conclusions

Closure with sutures is associated with lower risks of superficial infection and prolonged discharge than closure with staples following hip arthroplasty, but it may take more time.

Randomized Controlled Trial of Topical Skin Adhesive vs Nylon Sutures for Incision Closure in Forefoot Surgery

BACKGROUND

There are many options for incision closure in forefoot surgery. The aim of this study was to compare topical skin adhesive (2-octyl-cyanoacrylate) to simple interrupted nylon sutures.

METHODS

A prospective randomized controlled trial comparing topical skin adhesive (TSA) and nylon sutures (NSs) for elective open forefoot surgery. Primary outcome was Hollander Wound Evaluation Scale (HWES) assessed 2 weeks following surgery. Secondary objectives included time taken for wound closure, wound assessment, patient satisfaction with wound cosmesis, incision pain, and infection rate.

RESULTS

Between January and December 2018, 84 feet (70 patients) underwent hallux valgus scarf/Akin osteotomy or first metatarsophalangeal arthrodesis and were randomized to receive either intervention (topical skin adhesive) or control (3/0 nylon sutures). We found worse HWES scores when using TSA compared to NSs (1.07 vs 0.60). Incision closure time was slower for TSA (mean, 272 vs 229 seconds). At 2 weeks postoperatively, wound care was faster for TSA (mean 71 secs) vs NSs (mean 120), and patient-reported pain was less with TSA (visual analog scale: TSA 1.2 vs NSs 2.1). A high degree of overall patient satisfaction was reported in both groups, without significant difference.

CONCLUSION

Closure of elective forefoot surgery incisions with topical skin adhesive or interrupted nylon sutures offers high satisfaction rates, low pain scores, and low complications. However, topical skin adhesive was associated with more inflammation and areas of wound separation compared to nylon sutures. We recommend the use of sutures for wound closure in forefoot surgery.

LEVEL OF EVIDENCE

Level I, randomized controlled trial.

Subcuticular sutures versus staples for skin closure after primary hip arthroplasty

High-quality and cost-effective health care are highly recommended especially in joint replacement surgeries, particularly in total hip arthroplasty. Therefore, it is indispensable for orthopaedic surgeons to spot the potential areas of quality improvement. Evaluating the efficacy of the different ways of skin closure is an unacknowledged topic. We performed this study following both the Preferred Reporting Items for Systematic Reviews and Meta- analyses Statement (PRISMA) and the Cochrane Handbook for systematic reviews and meta-analysis. Articles were from any country, written in any language. We included all randomised control trials and retrospective cohort studies undergoing primary total hip arthroplasty who either received staples or subcuticular sutures for skin closure. The primary outcome was the incidence of wound infection. Secondary outcomes included length of stay (LOS), time to skin closure, total cost, and patient’s satisfaction. We included five studies in our cumulative meta- analysis. We conducted them using Review Manager V.5.0. We computed the risk ratio as a measure of the treatment effect, taking into account heterogeneity. We used Random-effect models. Primary skin closure with subcuticular sutures had insignificant marginal advantages for wound infections, LOS, and wound oozing. On the contrary, staples were more cost- effective and had less time for closure with higher patient’s satisfaction. Except for closure time and patient satisfaction , no significant difference between the two groups. The use of staples after THA may have several slight clinical advantages over the subcuticular sutures. However, owing to the complexities associated with wound closure, future clinical and laboratory studies assessing their complication outlines must be examined before an optimum technique can be determined.

Subcuticular Sutures Versus Staples for Wound Closure in Open Liver Resection: A Randomised Clinical Trial

BACKGROUND

Subcuticular sutures reduce wound complication rates only in clean surgeries. Repeat resection is frequently required in liver surgery, due to the high recurrence rate (30-50%) of liver cancers. The aim of this study is to assess that subcuticular sutures is superior to staples in liver surgery.

METHODS

This single-centre, single-blinded, randomised controlled trial was conducted at a university hospital between January 2015 and October 2018. Patients were randomly assigned (1:1) to receive either subcuticular sutures or staples for skin closure. Three risk factors (repeat resection, diabetes mellitus and liver function) were matched preoperatively for equal allocation. The primary endpoint was the wound complication rate, while secondary endpoints were surgical site infection (SSI), duration of postoperative hospitalisation and total medical cost. Subset analyses were performed only for the 3 factors allocated as secondary endpoints.

RESULTS

Of the 581 enrolled patients, 281 patients with subcuticular sutures and 283 patients with staples were analysed. As the primary outcome, the wound complication rate with subcuticular sutures (12.5%) did not differ from that with staples [15.9%; odds ratio (OR), 1.33; 95% confidence interval (CI), 0.83-2.15; p = 0.241]. As secondary outcomes, no significant differences were identified between the two procedures in the overall cohort while overall wound complications [7 patients (8.5%) vs. 17 patients (20.0%); OR, 2.68; 95% CI, 1.08-7.29; p = 0.035] with repeat incision were significantly less frequent with subcuticular sutures.

CONCLUSION

Subcuticular sutures were not shown to reduce wound complications compared to staples in open liver resection, but appear beneficial for repeat incisions.

Effect of Wound Closure Technique in Proximal Femoral Fractures: A Prospective Cohort Study

OBJECTIVES

To compare the effect of different wound closure techniques on wound drainage, postoperative length of stay, and complications in patients with proximal femoral fractures, including femoral neck fractures (31A fractures) and peritrochanteric fractures (31B fractures).

DESIGN

Prospective cohort study.

SETTING

Footscray Hospital, Western Health, Victoria, Australia; an acute teaching hospital.

PATIENTS AND PARTICIPANTS

All inpatients receiving surgery for proximal femoral fractures at our facility between May 2016 and August 2017. A total of 486 consecutive patients who presented during the study period were included in the study.

INTERVENTION

Three cohorts of consecutive patients were assigned to use either skin staples, monofilament absorbable subcuticular sutures (Monocryl), or, sutures with the addition of 2-octylcyanoacrylate (OCA) (Monocryl and Dermabond), respectively, for skin closure according to when the patients entered the study.

MAIN OUTCOME MEASUREMENTS

The primary outcome of interest was prolonged wound drainage measured using a standardized technique after postoperative day 3. Secondary outcomes included inpatient length of stay and overall complications.

RESULTS

We found a statistically significant increase in prolonged wound drainage in the staples cohort compared with the subcuticular sutures cohort and the sutures and OCA cohort (21.1% vs. 8.5% vs. 4.4%, P < 0.001). Inpatient length of stay was also significantly increased in the staples cohort (5.83 days vs. 4.78 days vs. 5.5 days, P = 0.005). There were no statistically significant differences between the 3 cohorts when comparing incidence of any medical complications, withholding of thromboprophylactic agents, or usage of topical negative pressure dressings.

CONCLUSIONS

In patients with proximal femoral fractures, closure with staples has the highest rate of prolonged wound drainage and length of stay. Subcuticular sutures in combination with OCA result in the lowest incidence of prolonged wound drainage.

LEVEL OF EVIDENCE

Therapeutic Level II. See Instructions for Authors for a complete description of levels of evidence.

A combination of subcuticular sutures and subcutaneous closed-suction drainage reduces the risk of incisional surgical site infection in loop ileostomy closure

PURPOSE

The purpose of this study was to evaluate the effectiveness of a wound closure method using a combination of subcuticular sutures and subcutaneous closed-suction drainage (SS closure) for preventing incisional surgical site infection (SSI) in loop ileostomy closure.

METHODS

A total of 178 consecutive patients who underwent loop ileostomy closure at Nara Medical University Hospital between 2004 and 2018 were retrospectively assessed. The patients were divided into 2 groups: the conventional skin closure (CC) group from 2004 to 2009 (75 patients) and the SS closure (SS) group from 2010 to 2018 (103 patients). The incidence of incisional SSI was compared between the two groups, and the factors associated with incisional SSI were examined by univariate and multivariate analyses.

RESULTS

Incisional SSI occurred in 7 cases (9.3%) in the CC group but was significantly reduced to only 1 case (0.9%) in the SS group (p = 0.034). In the univariate analysis, the hemoglobin levels, serum creatinine levels, and SS closure were associated with incisional SSI. SS closure was the only independent preventive factor for incisional SSI according to the multivariate analysis (hazard ratio = 0.24, p = 0.011).

CONCLUSION

The combination of subcuticular sutures and subcutaneous closed-suction drainage may be a promising way of preventing incisional SSI in loop ileostomy closure.

Wound complications after total hip arthroplasty: a prospective, randomised controlled trial comparing staples with sutures

OBJECTIVE

Does the use of staples or sutures for wound closure have a lower surgical site infection rate in patients receiving primary total hip arthroplasty (THA)?

DESIGN

Prospective, randomised controlled multicentre trial.

METHODS

535 patients undergoing THA were included and randomised into 2 groups: 268 wounds were closed with staples, and 267 with sutures. Primary outcome was surgical site infection (SSI). Secondary outcomes were prosthetic joint infection (PJI), other wound complications (dehiscence, necrosis and prolonged drainage) and duration of admittance. Follow-up occurred at 2, 6, and 12 weeks, and at 1 year.

RESULTS

There were no significant demographic differences between the 2 groups. SSI occurred more frequently when wounds were closed with staples (4% compared to 1% with sutures; OR 2.8; CI, 0.885-0.952; p = 0.057). SSI was treated with oral antibiotics. The staples group showed significantly more wound complications (17% compared to 5%; OR 3.943, CI 2.073-7.498; p = 0.000). Wound discharge was significantly prolonged in the staples group (n = 40, compared to n = 12 in the sutures group; OR 3.728; CI, 1.909-7.281; p = 0.000). There was no significant difference in PJI (p = 0.364).

CONCLUSIONS

In this large RCT comparing staples with sutures after THA, the use of staples is associated with a nearly 3 times greater risk of SSI (OR 2.8; p = 0.057). Staples significantly prolong wound discharge. The use of sutures for wound closure after THA is advised.

Surgical wound closure by staples or sutures?: Systematic review

AIM

To compare the effects of sutures and staples for skin closure of surgical wounds.

MATERIAL AND METHODS

We included published and unpublished randomized controlled trials (RCTs) and cluster-randomized trials comparing staples with sutures. Patients were adults (aged 18 years or over) who had undergone any type of surgery. The primary outcomes were risk of overall and severe wound infection. Secondary outcomes included length of hospital stay, readmission rate, adverse events, patient satisfaction with cosmetic results, postoperative pain.

RESULTS

Forty-two very low to low quality RCTs with a total of 11,067 patients were included. Sutures resulted in slightly fewer overall wound infections (4.90%) compared to staples (6.75%) but it is uncertain whether there is a difference between the groups (risk ratio [RR] 1.20, 95% confidence intervals [CI] 0.80-1.79; patients = 9864; studies = 34; I = 70%). The evidence was also insufficient to state a difference in terms of severe wound infection (staples 1.4% vs sutures 1.3%; RR 1.08, 95% CI 0.61-1.89; patients = 3036; studies = 17; I = 0%), grade of satisfaction (RR 0.99, 95% CI 0.91-1.07; patients = 3243; studies = 14; I = 67%) and hospital stay. Staples may increase the risk of adverse events (7.3% for staples vs 3.5% for sutures; RR 2.00, 95% CI 1.44-2.79; patients = 6246; studies = 21; I = 33%), readmission rate (RR 1.28, 95% CI 0.18-9.05; patients = 2466; studies = 5; I = 66%) and postoperative pain (standardized mean difference [SMD] 0.41,95%CI -0.35 to 1.16; I = 88%, patients = 390 patients, studies = 5).

CONCLUSIONS

Due to the lack of high quality evidence, we could not state if sutures are better than staples in terms of wound infection, readmission rate, adverse events, and postoperative pain. With a low quality of evidence, sutures reduce postoperative pain and improve grade of satisfaction with the cosmetic outcome.

Barbed sutures versus staples for closure in total hip arthroplasty using wound ooze as a primary outcome measure: A prospective study

BACKGROUND

Prosthetic joint infection is a rare, but devastating complication of primary total hip arthroplasty (THA). Postoperative wound discharge and deep infection are related. We examined whether barbed sutures were associated with a decrease in the incidence of postoperative wound discharge when compared with skin closure using metal staples.

METHODS

Prospective nonrandomized comparison between two groups (35 barbed suture closures vs. 49 staple closures). Wounds were assessed daily for postoperative wound discharge until dry. Hemoglobin and hematocrit were recorded at the preoperative assessment and on day 3 postoperative.

RESULTS

There were no significant differences between the groups with regard to age, body mass index, gender, preoperative hemoglobin, preoperative hematocrit, or estimated blood volume. The number of days elapsed until the wound was dry was significantly lower in the barbed suture group than the staples group (p < 0.0001). In the staples cohort, ongoing wound ooze resulted in delayed hospital discharge in three (6%) patients, six bed days total.

CONCLUSION

Barbed sutures reliably reduce the period of postoperative wound ooze following primary THA compared to staple closure. The use of barbed sutures may prevent delayed patient discharge from hospital, decreasing the bed burden.

Subcuticular sutures for skin closure in non-obstetric surgery

BACKGROUND

Following surgery, surgical wounds can be closed using a variety of devices including sutures (subcuticular or transdermal), staples and tissue adhesives. Subcuticular sutures are intradermal stitches (placed immediately below the epidermal layer). The increased availability of synthetic absorbable filaments (stitches which are absorbed by the body and do not have to be removed) has led to an increased use of subcuticular sutures. However, in non-obstetric surgery, there is still controversy about whether subcuticular sutures increase the incidence of wound complications.

OBJECTIVES

To examine the efficacy and acceptability of subcuticular sutures for skin closure in non-obstetric surgery.

SEARCH METHODS

In March 2019, we searched the Cochrane Wounds Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL); Ovid MEDLINE (including In-Process & Other Non-Indexed Citations); Ovid Embase and EBSCO CINAHL Plus. We also searched clinical trials registries for ongoing and unpublished studies, and scanned reference lists of relevant included studies as well as reviews, meta-analyses and health technology reports to identify additional studies. There were no restrictions with respect to language, date of publication or study setting.

SELECTION CRITERIA

All randomised controlled trials which compared subcuticular sutures with any other methods for skin closure in non-obstetric surgery were included in the review.

DATA COLLECTION AND ANALYSIS

Two review authors independently identified the trials, extracted data and carried out risk of bias and GRADE assessment of the certainty of the evidence.

MAIN RESULTS

We included 66 studies (7487 participants); 11 included trials had more than two arms. Most trials had poorly-reported methodology, meaning that it is unclear whether they were at high risk of bias. Most trials compared subcuticular sutures with transdermal sutures, skin staples or tissue adhesives. Most outcomes prespecified in the review protocol were reported. The certainty of evidence varied from high to very low in the comparisons of subcuticular sutures with transdermal sutures or staples and tissue adhesives; the certainty of the evidence for the comparison with surgical tapes and zippers was low to very low. Most evidence was downgraded for imprecision or risk of bias. Although the majority of studies enrolled people who underwent CDC class 1 (clean) surgeries, two-thirds of participants were enrolled in studies which included CDC class 2 to 4 surgeries, such as appendectomies and gastrointestinal surgeries. Most participants were adults in a hospital setting. Subcuticular sutures versus transdermal sutures There may be little difference in the incidence of SSI (risk ratio (RR) 1.10; 95% confidence interval (CI) 0.80 to 1.52; 3107 participants; low-certainty evidence). It is uncertain whether subcuticular sutures reduce wound complications (RR 0.83; 95% CI 0.40 to 1.71; 1489 participants; very low-certainty evidence). Subcuticular sutures probably improve patient satisfaction (score from 1 to 10) (at 30 days; MD 1.60, 95% CI 1.32 to 1.88; 290 participants; moderate-certainty evidence). Wound closure time is probably longer when subcuticular sutures are used (MD 5.81 minutes; 95% CI 5.13 to 6.49 minutes; 585 participants; moderate-certainty evidence). Subcuticular sutures versus skin staples There is moderate-certainty evidence that, when compared with skin staples, subcuticular sutures probably have little effect on SSI (RR 0.81, 95% CI 0.64 to 1.01; 4163 participants); but probably decrease the incidence of wound complications (RR 0.79, 95% CI 0.64 to 0.98; 2973 participants). Subcuticular sutures are associated with slightly higher patient satisfaction (score from 1 to 5) (MD 0.20, 95% CI 0.10 to 0.30; 1232 participants; high-certainty evidence). Wound closure time may also be longer compared with staples (MD 0.30 to 5.50 minutes; 1384 participants; low-certainty evidence). Subcuticular sutures versus tissue adhesives, surgical tapes and zippers There is moderate-certainty evidence showing no clear difference in the incidence of SSI between participants treated with subcuticular sutures and those treated with tissue adhesives (RR 0.77, 95% CI 0.41 to 1.45; 869 participants). There is also no clear difference in the incidence of wound complications (RR 0.62, 95% CI 0.35 to 1.11; 1058 participants; low-certainty evidence). Subcuticular sutures may also achieve lower patient satisfaction ratings (score from 1 to 10) (MD -2.05, 95% CI -3.05 to -1.05; 131 participants) (low-certainty evidence). In terms of SSI incidence, the evidence is uncertain when subcuticular sutures are compared with surgical tapes (RR 1.31, 95% CI 0.40 to 4.27; 354 participants; very low-certainty evidence) or surgical zippers (RR 0.80, 95% CI 0.08 to 8.48; 424 participants; very low-certainty evidence). There may be little difference in the incidence of wound complications between participants treated with subcuticular sutures and those treated with surgical tapes (RR 0.90, 95% CI 0.61 to 1.34; 492 participants; low-certainty evidence). It is uncertain whether subcuticular sutures reduce the risk of wound complications compared with surgical zippers (RR 0.55, 95% CI 0.15 to 2.04; 424 participants; very low-certainty evidence). It is also uncertain whether it takes longer to close a wound with subcuticular sutures compared with tissue adhesives (MD -0.34 to 10.39 minutes; 895 participants), surgical tapes (MD 0.74 to 6.36 minutes; 169 participants) or zippers (MD 4.38 to 8.25 minutes; 424 participants) (very low-certainty evidence). No study reported results for patient satisfaction compared with surgical tapes or zippers.

AUTHORS' CONCLUSIONS

There is no clear difference in the incidence of SSI for subcuticular sutures in comparison with any other skin closure methods. Subcuticular sutures probably reduce wound complications compared with staples, and probably improve patient satisfaction compared with transdermal sutures or staples. However, tissue adhesives may improve patient satisfaction compared with subcuticular sutures, and transdermal sutures and skin staples may be quicker to apply than subcuticular sutures. The quality of the evidence ranged from high to very low; evidence for almost all comparisons was subject to some limitations. There seems to be no need for additional new trials to explore the comparison with staples because there are high-quality studies with large sample sizes and some ongoing studies. However, there is a need for studies exploring the comparisons with transdermal sutures, tissue adhesives, tapes and zippers, with high-quality studies and large sample sizes, including long-term assessments.

Tissue adhesive for wound closure in enhanced-recovery total hip arthroplasty: a prospective, randomized and controlled study

Background

We aimed to present our experience of adopting tissue adhesive as adjunct to standard wound closure in total hip arthroplasty (THA) and evaluate its performance.

Methods

From September 2019 to November 2019, we prospectively enrolled consecutive patients who underwent simultaneous bilateral THA in this randomized and controlled study. Standard wound closure was applied on one side of hip while additional tissue adhesive was applied on the other side at random. We collected and analyzed patients’ information, including age, gender, body mass index (BMI), diagnosis, postoperative length of stay (LOS), dressing changes, wound evaluation scores, wound-related cost and complications.

Results

Thirty patients with simultaneous bilateral THA were enrolled in this study. During the hospital stay, the times of dressing change in hips with tissue adhesive was significantly less than that in the other hips (p = 0.000). However, the wound-related cost in hips with tissue adhesive was significantly higher (p = 0.000). According to patients’ feedback at one-month follow-up, wound evaluation of hips with tissue adhesive was significantly better than the other hips (p = 0.004). Seventeen patients preferred tissue adhesive and only five patients preferred standard wound closure.

Conclusions

Tissue adhesive could significantly reduce wound drainage and increase patients’ satisfaction, which can be an ideal adjunct to standard wound closure in enhanced-recovery THA.

Subcuticular sutures in laparoscopic colorectal surgery: a comparative study to evaluate wound infection rates and cosmetic results

Laparoscopic colorectal surgery is categorized as clean-contaminated surgery. It is important to prevent incisional surgical site infections (SSIs), because SSIs can prolong hospital stays, increase medical costs and produce negative cosmetic outcomes for patients. The aim of this study is to evaluate the efficacy of subcuticular skin sutures following colorectal laparoscopic surgery in terms of wound infection rates and aesthetic results. A retrospective analysis on a database of a consecutive series of unselected patients was conducted. Patients underwent elective colorectal laparoscopic surgery in a single center between October 1st of 2016 and October 30th of 2017. Data on patients' demographics, operative details, short-term and long-term outcomes and aesthetic satisfaction were prospectively recorded. A total of 100 patients were selected and divided in 2 groups: 43 patients who had received subcuticular sutures, 57 patients who had received separate stitch sutures. Wound infection rates were lower, with no statistical significance in the subcuticular suture group (6.9% versus 15.8%, p = 0.182), but the patient-reported cosmetic results were superior in the subcuticular suture group (1.9 versus 2.9, p < 0.001). Multivariate analyses identified high BMI and low preoperative hemoglobin level as possible risk factors associated with wound infection after colorectal laparoscopic surgery. Subcuticular sutures could improve cosmetic results in patients undergoing elective laparoscopic surgery for colorectal cancer with comparable risks of wound infection. In this population, high BMI and low preoperative hemoglobin levels appear to be risk factors associated with wound infections.

Comparison of skin closure techniques in patients undergoing open pancreaticoduodenectomy: A single center experience

BACKGROUND

This study evaluated closure techniques and incisional surgical site complications (SSCs) and incisional surgical site infections (SSIs) after pancreaticoduodenectomy (PD).

METHODS

Retrospective review of open PDs from 2015 to 2018 was performed. Outcomes were compared among closure techniques (subcuticular + topical skin adhesive (TSA); staples; subcuticular only). SSCs were defined as abscess, cellulitis, seroma, or fat necrosis. SSIs were defined according to the National Surgical Quality Improvement Program (NSQIP).

RESULTS

Patients with subcuticular + TSA (n = 205) were less likely to develop an incisional SSC (9.8%) compared to staples (n = 139) (20.1%) and subcuticular (n = 74) (16.2%) on univariable analysis (P = 0.024). Multivariable analysis revealed no statistically significant difference in incisional SSC between subcuticular + TSA and subcuticular (P = 0.528); a significant difference remained between subcuticular + TSA and staples (P = 0.014). Unadjusted median length of stay (LOS) (days) was significantly longer for staples (9) vs. subcuticular (8) vs. subcuticular + TSA (7); P < 0.001. Incisional SSIs were evaluated separately according to the NSQIP definition. When comparing rates, the subcuticular + TSA group experienced lower incisional SSIs compared to the other two techniques (4.9% vs. 10.1%, 10.8%). However, this difference was not statistically significant by either univariable or multivariable analysis.

CONCLUSIONS

Subcuticular suture + TSA reduces the risk of incisional SSCs when compared to staples alone after pancreaticoduodenectomy.

Skin Closure Tape and Surgical Staples in Primary Total Knee Arthroplasty: A Systematic Review and Meta-Analysis

Background

Staples closure technology has been widely used in total knee arthroplasty (TKA) and achieved good results. In recent years, a new type of material called skin closure tape (SCT) has been applied to TKA which also showed good treatment results. However, since it is still not clear yet which one is better, this paper collects literatures for statistical analysis so as to provide evidence for the use of SCT in TKA.

Methods

The comparative study on effects between SCT and staples is reviewed after the primary release of TKA in PubMed, the Cochrane library, and the EMBASE database up to March 2019. The two researchers independently screened the literature and evaluated the quality of the literature using bias risk tools.

Results

A total of four studies (3330 knees) have been included in our meta-analysis. For the main point, the results show that the SCT can reduce readmission rates compared to staples (RR 0.68, 95% CI 0.49–0.95, P=0.03), with no significant difference in complications (RR 0.85, 95% CI 0.27–2.64, P=0.77). Secondly, the results suggest that although there is no significant difference in removal time between the two groups, the SCT can reduce pains, save time and costs, and have a better cosmetic effect.

Conclusions

Our study indicates SCT as a closure method with fewer complications and faster speed compared with staples. Nevertheless, the cost and pain need to be further confirmed because of the small sample size included in this study.

A double-blinded randomised controlled trial - do subcuticular non-absorbable skin sutures have a better aesthetic outcome than skin staples in large wound closures?

Introduction: Traditionally, non-absorbable skin sutures (SS) have been utilised in the closure of the skin in large wounds. More recently, however, skin staples (SC) have been introduced with the aim of reducing closure time and infection rates.

Method: A double-blinded randomized controlled trial in all patients undergoing elective open surgeries in a single unit, from May 2007 to May 2010. Data on patient demographics, type of surgery, methods of skin closure, rate of wound infection and cosmetic satisfaction were collected. Patients were then randomly allocated to skin sutures (SS) or skin staples (SC) groups. Patients and investigators were then “blinded” to the arm of trial they were allocated to.

Result: In total, 369 patients were recruited, of which 218 patients completed the study. 134 patients were allocated to the SS group with a median age of 67 (IQR 61, 74). SC group had a total of 84 patients with a median age of 69 (IQR 61, 71). 15% of SS group developed wound infection, compared to 20% in SC group (p=0.202). 61% of the SS group claimed better aesthetic results compared to 46% in SC group (p=0.020).

Conclusion: Our results demonstrated that patients with non-absorbable subcuticular skin closures had lower infection rates, better cosmetic outcome and better patient satisfaction outcome compared with skin staples. We therefore suggest using subcuticular sutures to close the skin in elective abdominal open surgery.

Nylon sutures versus skin staples in foot and ankle surgery: is there a clinical difference?

BACKGROUND

Staple sutures have already been proven as a good alternative to nylon sutures for wound closure in hip and knee surgeries. One such advantage to using staple sutures is the significant decrease in surgical time. In foot surgeries, staple sutures are still considered critical and are only used sporadically.

OBJECTIVE

The aim of this retrospective study was to compare nylon sutures and skin staples for wound closure in foot and ankle surgeries with respect to complications and patient satisfaction.

METHODS

A total of 61 patients underwent different operations in the fore-, mid-, and hindfoot areas, which were performed by a single surgeon. Twenty-nine patients received staple wound closures, while 32 patients received nylon suture closures using the Donati back-and-forth technique. Incision length, surgery time, in-patient stay, and wound complications were recorded. Furthermore, a patient survey using the verbal numeric rating scale (VNRS) for subjective pain and cosmetic results at the time of stitch removal (14 days) and after a 6-week follow-up was conducted.

RESULTS

A significant between-group difference was found for surgery time (p = .041) and VNRS for pain (p < .001), with better results seen for staple sutures. Four patients with staple sutures and five with nylon sutures experienced wound dehiscence 14 days postoperatively. However, all patients had completely healed wounds at their 6-week follow-up. No revisional surgeries were necessary.

CONCLUSION

The present results indicate that a skin staple wound closure is a considerable alternative to the nylon suture closure in foot and ankle surgeries. Nevertheless, further prospective randomized trials must cement these insights.

Is the Risk of Infection Lower with Sutures than with Staples for Skin Closure After Orthopaedic Surgery? A Meta-analysis of Randomized Trials

BACKGROUND

Two previous meta-analyses comparing staples versus sutures have led to conflicting relative risks for surgical site infection between skin closure methods after orthopaedic surgery. Consequently, the choice of sutures or staples for skin closure continues to be a subject of conversation. Recently, additional randomized trials have been published, and an updated meta-analysis is needed to inform this debate.

QUESTIONS/PURPOSES

To determine using a meta-analysis of randomized trials (1) whether there is a difference in surgical site infection (SSI) between staples and sutures for skin closure after orthopaedic surgery, and (2) whether that finding remains the same when the analysis is limited to randomized trials with a low risk of bias.

METHODS

A systematic review and meta-analysis of randomized controlled trials (RCTs) comparing staples with sutures for skin closure after orthopaedic surgery was conducted. We excluded barbed sutures, surgical zippers, and skin adhesives from this meta-analysis. Medline, Embase, CINAHL, Cochrane Library, and Global Index Medicus were searched from date of inception to October 18, 2017. The sole outcome of interest was SSI as defined by the original study authors, with preference given to Center for Disease Control and Prevention (CDC) definitions whenever possible, recognizing that this may result in the pooling of more common minor events with rarer, more severe events, and in so doing, overestimate between-group differences. Because of this, subgroup analysis was planned based on severity of infection. Relative risk was calculated using a random-effects model (relative risk [RR], 95% confidence interval [CI]). Heterogeneity was estimated using I. Publication bias was explored using visual inspection of the funnel plot and Egger's test. Subgroup analysis was planned for type of orthopaedic surgery, suture material, SSI category, and country development index. Subgroup interaction p values were calculated. The Cochrane risk of bias tool was used to assess study quality. Sensitivity analysis was planned to assess whether the results changed when the analysis was limited to studies with low risk of bias. In total, 17 RCTs (2446 patients) were eligible, of which five RCTs (501 patients) were at low risk of bias.

RESULTS

In the primary analysis, patients randomized to staples had a higher risk of SSI versus those who received sutures for skin closure (RR, 2.05; 95% CI,1.38-3.06; I = 0%). However, most of the events were driven by superficial SSI, and only two deep infections were explicitly reported in total (one in each group). After a post-hoc sensitivity analysis excluded a highly influential trial with high risk of bias, the results were highly fragile, relying on a difference of only four additional events in the staples group. When we limited the analysis to RCTs with low risk of bias, no difference was found between sutures and staples in terms of SSI (RR, 1.45; 95% CI, 0.31-6.79; I = 46%). Effect sizes were consistent across subgroups (p value for subgroup interaction was not significant for elective versus trauma; hip versus knee arthroplasty; suture material; high versus middle- versus low-income settings).

CONCLUSIONS

Even in this relatively large meta-analysis, existing RCTs do not provide definitive evidence of a difference in SSI risk when staples are used instead of sutures for skin closure after orthopaedic surgery. Currently, the total body of evidence remains weak and, even when limiting to only low risk of bias studies, it is not possible to rule in or rule out clinically important differences between staples and sutures. Until randomized studies of adequate power and followup duration are performed to definitively inform this issue, the choice between staples versus sutures should be based on other factors such as local availability, surgeon preference, and cost.

Non-invasive, Zip Type Skin Closure Device vs. Conventional Staples in Total Knee Arthroplasty: Which Method Holds Greater Potential for Bundled Payments?

Introduction: A new, noninvasive zip surgical skin closure device has recently been introduced into the market and introduces a new alternative to the traditional staple closure method which has dominated the industry for many years.

Methods: This was a retrospective chart review and case study of a consecutive series of 130 patients who underwent primary total knee arthroplasty (TKA) from April 2016 to November 2016. The first 65 patients in this series underwent a primary TKA utilizing the standard staple closure method (staple group). The next 65 patients underwent a primary TKA through the new zip surgical skin closure method (zip group). Charts were reviewed for incision-related phone calls to the clinic, additional clinic visits due to incision concerns, antibiotic prescriptions due to incision complications, and incision-related emergency room (ER) admits.

Results: The staple group had a significantly higher amount of incision-related phone calls made to the clinic as compared to the zip group (20 versus 8, P < .05, respectively). The staple group also had more incision-related ER admits, more incision-related clinic visits, and more antibiotics prescribed due to incisional complications than the zip group (1 versus 0, 5 versus 2, and 4 versus 1, respectively), although it was not proven to be significant (P > .05).

Conclusion: This is the largest patient cohort study comparing the noninvasive zip-type closure device to staple closures in TKA cases and provides insight on how a simple change in the closure methodology can lead to many potential downstream savings when considering a bundled payment model.

Concealed cosmetic closure in total knee replacement surgery - A prospective audit assessing appearance and patient satisfaction

OBJECTIVE

With the trend towards accelerated rehabilitation, the method of skin closure has become increasingly important in orthopedic surgery. It is imperative to evaluate a technique that provides superior clinical and cosmetic results specifically for TKA, due to relatively thin skin anterior to the knee making poor wound healing an issue of concern. We conducted a prospective, single-arm audit evaluating the patient assessments of incision cosmesis for a novel technique in TKA wound closure called Concealed Cosmetic Closure (CCC).

METHODS

570 knees were included in the study whose wound was closed with concealed cosmetic subcuticular interrupted sutures (CCCIS) between January 2014 and May 2016. A validated, ordinal questionnaire, Stony Brooks Scar Evaluation Scale (SBSES) designed to elicit a score evaluating scar satisfaction was interviewed by the investigators to patients 6 months to 3 years postoperatively.

RESULTS

CCC is a simple and relatively rapid single-operator technique that takes about 7-10 min to close 11-17 cm knee incision. In our study, the mean score for Stony Brook Scar Evaluation Scale (SBSES) was 4.4 (SD of 0.73) (range 3-5). The scar was rated highly in terms of cosmesis, patient satisfaction and appearance of the wound.

CONCLUSION

CCC is an effective modality for skin closure in total knee arthroplasty providing superior cosmetic healing with minimal complications leading to improved long term patient satisfaction.

Staple versus suture closure for ankle fracture fixation: Retrospective chart review for safety and outcomes

INTRODUCTION/AIM

Recent comparisons of suture versus metal staple skin closure on the rates of wound complications in orthopaedic surgeries have yielded conflicting results. Several studies have since started to approach this question based on anatomic location, comparing suture versus staple closure in total hip and knee arthroplasty and acetabulum fracture surgery. Ankle fractures are one of the most commonly treated fractures by orthopaedic surgeons with unique challenges to skin closure due to the lack of subcutaneous support. However, to date there are no studies comparing superficial skin closure methods specifically in ankle surgery. The objective of this study was to evaluate the safety of staple versus suture closure for open fixation of acute traumatic ankle fractures.

METHODS

The medical records of patients treated at one institution by a single surgeon with open surgical fixation of an acute traumatic ankle fracture between 2011 and 2017 were retrospectively reviewed. Patients with less than 6 months of follow-up, polytrauma patients, diabetic patients, and patients with more than 3 medical comorbidities were excluded. Skin closure technique was determined by the presence or absence of metallic staples on postoperative imaging. Demographic variables, surgical characteristics, and postoperative outcomes up to one year were compared between patients who received superficial skin closure using staple versus suture techniques. Statistical analysis was performed using chi-squared tests and Fisher's exact tests, with p=0.05 used to denote statistical significance.

RESULTS

This study included 94 patients aged 18 to 75: two groups of 47 patients (Staple group and Suture group) that were demographically similar at baseline. Overweight and obese patients constituted the majority of the sample, 34% and 46% of patients, respectively. Current tobacco use was reported by 45% of patients. Fractures tended to be right-sided (63%), low energy (64%), and closed (98%), and the most common fracture types were bimalleolar (30%), lateral malleolar (24%), and pilon (19%) fractures. Ten patients (10.6%) developed local wound related complications within 4 months postoperatively, including five incidences of wound dehiscence, four superficial wound infections, and one deep infection. Eight patients (8.5%) required revision surgery due to wound related complications. There was no difference in the incidence of surgical site infections (p=0.361), local wound related complications (p=0.316), or revision surgeries (p=0.267) between wound closure techniques. Suture group patients required more staff in the operating room compared with staple group patients (p=0.001).

CONCLUSION

These results suggest that staples are a safe alternative to sutures for superficial skin closure in healthy, non-diabetic patients following open surgical fixation of acute traumatic ankle fractures. However, this retrospective, single-institution study was limited by the low number of available patients relative to the rare outcomes of interest. Larger, prospective studies are needed to validate the accuracy and generalizability of these results.

A combination of subcuticular suture and enhanced recovery after surgery reduces wound complications in patients undergoing hepatectomy for hepatocellular carcinoma

The aim of this study was to examine whether using subcuticular sutures during initial hepatectomy for hepatocellular carcinoma is associated with shorter postoperative length of hospital stay (PLOS) than using staples for patients treated in the enhanced recovery after surgery (ERAS) approach. A total of 376 patients were randomized to receive either subcuticular sutures or staples (188 per group), and the two groups were compared in terms of the incidence of wound complications and PLOS. Independent risk factors for PLOS were identified by multivariate analysis. Sutures were associated with significantly lower incidence of wound infection (4.3% vs. 13.3%, P = 0.020) and significantly shorter PLOS (7.97 vs. 8.45 days, P = 0.048). Independent risk factors for wound infection after hepatectomy were advanced age, increased preoperative body mass index, decreased preoperative serum albumin, and skin closure using staples. These results suggest that subcuticular sutures may be more effective than staples for conducting hepatectomy in patients with hepatocellular carcinoma who receive ERAS care.

Superficial Surgical Site Infection in Hepatobiliary-Pancreatic Surgery: Subcuticular Suture Versus Skin Staples

PURPOSE

Postoperative superficial surgical site infection is a major complication in hepatobiliary-pancreatic surgery. We aimed to compare the efficacy of subcuticular sutures versus staples for skin closure in preventing superficial surgical site infection in hepatobiliary-pancreatic surgery.

METHODS

Consecutive patients who underwent hepatobiliary-pancreatic surgery at our hospital from October 2006 to March 2011 and from April 2012 to March 2015 were reviewed retrospectively. Superficial surgical site infection incidence was evaluated in patients who received subcuticular sutures and those who received staples for skin closure. Propensity score matching analysis was used to adjust bias from confounding factors.

RESULTS

A total of 691 patients were included. Patients with skin staple closures (n = 346) were compared with patients with subcuticular suture closures (n = 345). After a propensity score matching analysis, a significant difference in superficial surgical site infection incidence was found between the skin stapler group (11.3%) and subcuticular sutures group (2.6%). The same comparison was performed by a subgroup analysis and supported this finding in patients after hepatectomy without biliary reconstruction, pancreatoduodenectomy, or open laparotomy surgeries and in patients with body mass index < 25.

CONCLUSIONS

Subcuticular suturing after hepatobiliary-pancreatic surgery was more efficacious in reducing postoperative superficial surgical site infection incidence than staples for skin closure.

Skin closure following fractured neck of femur surgery: a survey of orthopaedic surgeons' practices

INTRODUCTION

Surgical intervention for patients presenting with a fractured neck of femur is common, however the best method of skin closure remains unclear. It has been suggested that the use of metallic skin clips in the closure of hip wounds may increase the rate of surgical site infections, however there are few high quality studies evaluating this.

METHODS

We designed a survey to assess surgeons preferred skin closure method and their reasons for choosing it. This was sent to 545 consultant orthopaedic surgeons.

RESULTS

The positive response rate to our survey was 68% (n = 370). The survey showed that 44% of surgeons used metallic skin clips, and this was the most common method of closure reported. Hip surgeons were less likely to use metallic skin clips when compared to surgeons with other principal subspecialty practices. Surgeons using clips were most likely to state the rationale for use as convenience, whereas those using non-clip skin closure methods were more likely to cite reduced rates of wound inflammation, discharge, and infection as the rationale for use. Only a small proportion of surgeons indicate that their decisions were evidence based.

CONCLUSIONS

Skin closure following surgery for fractured neck of femur is not consistent amongst surgeons and is not driven by evidence. Greater levels of evidence in this field are required to improve outcomes in this patient group.

Complication rate of different wound closures after primary hip arthroplasty - A survey of 373 patients

BACKGROUND

Wound closure is highly associated with wound complications and the best wound closure method was controversial in total hip arthroplasty.

METHODS

We performed a retrospective study of primary hip arthroplasty and compared three types of closure method.

RESULTS

155 cases were closed using continuous subcuticular sutures then with staples, 111 using staples, 141 using interrupted sutures. 28 cases of wound complications occurred. Wound complication rates in subcuticular suture group, staple group and interrupted suture group were 1.9%, 11.7% and 8.5%, respectively (p < 0.01).

CONCLUSION

Wound complication rate was significantly lower when wound was closed with continuous subcuticular suturue.

A prospective randomised comparison of 2 skin closure techniques in primary total hip arthroplasty surgery

INTRODUCTION

As an essential step of total hip arthroplasty (THA), an effective and secure skin closure technique after primary THA is important. Metallic staples closure and subcuticular suture are the 2 common techniques for skin closure. However, which closure technique is the optimal skin-closure method remains unclear. The purpose of this prospective randomised clinical study was to compare the clinical outcomes and costs between staples and subcuticular suture techniques.

METHODS

In this clinical study, 165 patients who underwent primary unilateral THA through a posterolateral approach from August 2014 to May 2015 were included. According to skin closure technique, the patients were randomised into staples group (interrupted suture with staples, 83 cases) and sutures group (running 4-0 absorbable subcuticular suture, 82 cases). The same operative and perioperative care were provided to all patients. The surgical site infections (SSIs) rate, closure time, time to dry wounds and postoperative hospital stay were recorded and compared. Besides, cosmetic results and patient's satisfaction were evaluated with Hollander wound evaluation score (HWES) and VAS score at postoperative 3 months follow-up respectively. Relative total costs were recorded as well.

RESULTS

It was shown that no infections developed in sutures group, while 2 postoperative superficial infections (2.4%) occurred in the staples group. There was a statistically significant difference in the time to dry surgical incisions and postoperative hospital stay favoring sutures (4.8 vs. 5.0 days, p = 0.028; 6.0 vs. 12.0 days, p<0.001, respectively). The cutaneous incision closure using staples consumed significantly less time than that with subcuticular suture (24.7 vs. 357.7 seconds, p<0.001). Moreover, there was no significant difference in HWES and patient's satisfaction between the 2 groups. Finally, the application of subcuticular suture saved an average of $82.2 per case.

CONCLUSIONS

Closure with running subcuticular suture is cheaper and appears to have a clinical advantage when compared with metallic staples skin closure in primary THA surgery. However, additional operating time may be incurred.

Allgöwer-Donati Versus Vertical Mattress Suture Technique Impact on Perfusion in Ankle Fracture Surgery: A Randomized Clinical Trial Using Intraoperative Angiography

OBJECTIVE

The purpose of this study was to evaluate which primary wound closure technique for ankle fractures affords the most robust perfusion as measured by laser-assisted indocyanine green angiography: Allgöwer-Donati or vertical mattress.

DESIGN

Prospective, randomized.

SETTING

Level 1 Academic Trauma Center.

PATIENTS/PARTICIPANTS

Thirty patients undergoing open reduction internal fixation for ankle fractures were prospectively randomized to Allgöwer-Donati (n = 15) or vertical mattress (n = 15) closure. Demographics were similar for both cohorts with respect to age, sex, body mass index, surgical timing, and OTA/AO fracture classification.

MAIN OUTCOME MEASUREMENTS

Skin perfusion (mean incision perfusion and mean perfusion impairment) was quantified in fluorescence units with laser-assisted indocyanine green angiography along the lateral incision as well as anterior and posterior to the incision at 30 separate locations. Minimum follow-up was 3 months with a mean follow-up 4.7 months.

RESULTS

Allgöwer-Donati enabled superior perfusion compared with the vertical mattress suture technique. Mean incision perfusion for Allgöwer-Donati was 51 (SD = 13) and for vertical mattress was 28 (SD = 10, P < 0.0001). Mean perfusion impairment was less in the Allgöwer-Donati cohort (12.8, SD = 9) compared with that in the vertical mattress cohort (23.4, SD = 14; P = 0.03). One patient in each cohort experienced a wound complication.

CONCLUSIONS

The Allgöwer-Donati suture technique offers improved incision perfusion compared with vertical mattress closure after open reduction internal fixation of ankle fractures. Theoretically, this may enhance soft tissue healing and decrease the risk of wound complications. Surgeons may take this into consideration when deciding closure techniques for ankle fractures.

Randomized Comparison of Subcuticular Sutures Versus Staples for Skin Closure After Open Abdominal Surgery: a Multicenter Open-Label Randomized Controlled Trial

BACKGROUND

The incisional surgical site infection (SSI) is an extremely common complication following open abdominal surgery and imposes a considerable treatment and cost burden.

METHOD

We conducted a multicenter open-label randomized controlled trial at three Tokyo Metropolitan medical institutions. We enrolled adult patients who underwent either an elective or an emergency open laparotomy. Eligible patients were allocated preoperatively to undergo wound closure with either subcuticular sutures or staples. A central Web-based randomization tool was used to assign participants randomly by a permuted block sequence with a 1:1 allocation ratio and a block size of 4 before mass closure to each group. The primary endpoint was the occurrence of a superficial SSI within 30 days after surgery in accordance with the Centers for Disease Control and Prevention criteria. This trial was registered with UMIN-CTR as UMIN 000004836 ( http://www.umin.ac.jp/ctr ).

RESULTS

Between September 1, 2010 and August 31, 2015, 401 patients were enrolled and randomly assigned to either group. One hundred and ninety-nine patients were allocated to the subcuticular suture and 202 patients to the staple groups (hereafter the "suture" and "staple" group, respectively). Three hundred and ninety-nine were eligible for the primary endpoint. Superficial SSIs occurred in 25 of 198 suture patients and in 27 of 201 staple patients. Overall, the rate of superficial SSIs did not differ significantly between the suture and staple groups.

CONCLUSION

Subcuticular sutures did not increase the occurrence of superficial SSIs following open laparotomies mainly consisting of clean-contaminated surgical procedures. The applicability of the wound closure material and method is likely to depend on individual circumstances of the patient and surgical procedure.

Skin staples versus intradermal wound closure following primary hip arthroplasty: a prospective, randomised trial including 231 cases

Intradermal wound closure is controversial in primary total hip arthroplasty. Randomised, controlled trials in wound closure following a total hip arthroplasty (THA) are scarce. Our hypothesis was that skin staples closure would be related to a similar complication rate and operative time as intradermal closure with polypropylene. From September 2011 to May 2012, 231 THAs in 219 patients with an average age of 62 years old (range: 21-91) were performed. No differences were observed in both groups according to sex, age, BMI and comorbidities (p = 0,82). Cases were divided into 3 groups according to medical factors that influence wound healing: group 1 (no medical history, 70.5%), group 2 (diabetes, tobacco smokers, obesity, corticosteroids, rheumatoid disease, 25%) and group 3 (organ transplantation, neoplastic patients or 2 or factors of group 2, 4.5%). Once randomised using a computer-generated method, all patients remained within the group to which they were allocated to wound closure with skin staples (Leukosan® SkinStapler PTW-35, BSN, Germany) that were used in 112 THAs in 105 patients (48%), or continuous 3.0 intradermal non-absorbable polypropylene suture (Prolene™ 0, Ethicon Inc. Somerville, New Jersey, USA) in 119 THA´s in 115 patients (52%). A 3.8% wound complication rate was observed in this series, with a 2.1% complication rate for the group that was closed with skin staples and a 1.7% rate for the group with intradermal suture (p = 0.7). All the complications were treated conservatively except for one acute deep infection (0.4%) that was successfully treated with debridement, component retention and intravenous antibiotics. There were no differences in both groups related to operative time or wound length.In these series of primary elective THAs, skin staples were associated with a similar complication rate to an intradermal closure technique.

Refinement of Tissue-Engineering Chamber Implantation in the Rat

PURPOSE

Rodent in vivo models that successfully generate new adipose, muscle, or vascular tissue in a tissue-engineering chamber (TEC) has advanced in the last decade. In this article, technical refinements in these operative foreign body implantations have been described to improve the execution of animal models in a way so that they can reduce wastage of time and resources.

MATERIALS & METHODS

Male Sprague-Dawley rats were studied and randomly divided into two equal sized groups. In each group, a different operative procedure was used for implanting the TEC. Twenty animals were operated with diagonal incisions in the groin region, followed by staples for wound closure after TEC implantation. The remaining 20 animals received longitudinal incisions in the abdominal region followed by wound closure with ongoing intradermal nonresorbable sutures and skin glue. The outcome of both procedures with regard to complications, animal growth, and experimental failure was compared. Statistical analysis was performed using the nonparametric chi-squared (χ²) test.

RESULTS

Significant difference in wound dehiscence was recorded in Group I as compared to Group II (p = 0.0001). Consequently, 55% of the experiments had to be aborted in Group I and the animals were removed from the experiment. On the contrary, in Group II, all the animals could be kept.

CONCLUSION

Median longitudinal incisions and thorough wound closure with ongoing intradermal nonresorbable sutures, followed by application of skin glue, are strongly recommended to prevent surgical site complications, such as wound dehiscence, animal harm, and failure of the individual experiment.

A randomised controlled trial comparing skin closure in total knee arthroplasty in the same knee: nylon sutures versus skin staples

OBJECTIVES

Nylon sutures and skin staples are used commonly in total knee arthroplasty (TKA) surgical wound closure. However, there is no study that compares the wound healing efficacy and patient satisfaction scores of both techniques in the same knee.

METHODS

We randomised 70 patients who underwent primary TKA into two groups. In one group of 34 patients, the skin at the upper half of the wound was closed with skin staples and the lower half of the wound was closed with simple interrupted nylon sutures. In the other group of 36 patients, the skin at the upper half of the wound was closed with nylon stitches and the lower half of the wound was closed with skin staples. We recorded the wound closure time, pain score at the time of stitch removal, wound complication rate, patient satisfaction score, and the Hollander wound evaluation score at the post-operative periods of five days, 14 days, six weeks, three months, and six months. Each half wound was analysed separately.

RESULTS

The mean patient body mass index was 26.8 kg/m(2) (standard deviation 6.3). A total of 70 nylon stitched wounds and 70 skin stapled wounds were analysed. There were no significant differences in wound complication rates, patient satisfaction score, and the Hollander wound evaluation score between both types of wounds (p > 0.05). The wound closure time for skin stapled wounds was significantly lower than the nylon stitched wounds (p < 0.001). However, the skin stapled wounds had a significantly higher pain score at the time of stitch removal (p < 0.001).

CONCLUSION

Skin staples and nylon stitches had comparable results with respect to wound healing and patient satisfaction in TKA wound closure in non-obese patients. The benefit of skin staples over nylon stitches was a decrease in operative time, but was more painful upon removal.Cite this article: V. Yuenyongviwat.

Do zip-type skin-closing devices show better wound status compared to conventional staple devices in total knee arthroplasty?

This study compared the pain score, cosmetic outcome and wound complication rate between zip-type skin-closing device and conventional staple device. Forty-five subjects with zip-type skin-closing device (the zip group) and 45 subjects with the conventional staple device (the staple group) after total knee arthroplasty were compared. Visual analogue scale score was significantly higher on postoperative (PO) 1, 3, 14 day (D) in the staple group compared to the zip group (P < 0·05). The Vancouver scar score was significantly better in the zip group compared to that of the staple group (4·6 ± 0·7 versus 6·9 ± 1·3, P = 0·043) on PO 90D. There was no significant wound complication rate between the two groups. The zip-type skin-closing device showed less pain PO 14D, especially during dressing and removal of the device, and better cosmetic outcome 3 months after surgeries. Surgeons may consider using the zip-type skin-closing device for patients who want less pain and better cosmetic outcome.

Comparing sutures versus staples for skin closure after orthopaedic surgery: systematic review and meta-analysis

OBJECTIVE

To determine whether there still remains a significant advantage in the use of sutures to staples for orthopaedic skin closure in adult patients.

DESIGN

Systematic Review/ Meta-Analysis.

DATA SOURCES

MEDLINE-OVID, EMBASE-OVID, CINAHL and Cochrane Library. Grey and unpublished literature was also explored by searching: International Clinical Trial Registry, Grey Matters BIOSIS Previews, Networked Digital Library of Theses and Dissertations, ClinicalTrials.gov, UK Clinical Trials Gateway, UK Clinical Research Network Study Portfolio, Open Grey, Grey Literature Report, and Web of Science.

SELECTION CRITERIA

Articles were from any country, written in English and published after 1950. We included all randomised control trials and observational studies comparing adults (≥ 18 years) undergoing orthopaedic surgery who either received staples or sutures for skin closure. The primary outcome was the incidence of surgical site infection. Secondary outcomes included closure time, inflammation, length of stay, pain, abscess formation, necrosis, discharge, wound dehiscence, allergic reaction and health-related quality of life.

RESULTS

13 studies were included in our cumulative meta-analysis conducted using Review Manager V.5.0. The risk ratio was computed as a measure of the treatment effect taking into account heterogeneity. Random-effect models were applied. There was no significant difference in infection comparing sutures to staples. The cumulative relative risk was 1.06 (0.46 to 2.44). In addition, there was no difference in infection comparing sutures to staples in hip and knee surgery, respectively. Lastly, except for closure time, there was no significant difference in secondary outcomes comparing sutures to staples.

CONCLUSIONS

Except for closure time, there was no significant difference in superficial infection and secondary outcomes comparing sutures to staples was found. Given that there may in fact be no difference in effect between the two skin closure and the methodological limitations of included studies, authors should begin to consider the economic and logistic implications of using staples or sutures for skin closure.

The Chitranjan Ranawat Award: Running Subcuticular Closure Enables the Most Robust Perfusion After TKA: A Randomized Clinical Trial

BACKGROUND

Maintaining robust perfusion is an important physiologic parameter in wound healing. The effect of different closure techniques on wound perfusion after total knee arthroplasty (TKA) has not been established previously and may have implications for wound healing.

QUESTIONS/PURPOSES

We asked whether a running subcuticular, vertical mattress, or skin staple closure technique enables the most robust wound perfusion after TKA as measured by laser-assisted indocyanine green angiography (LA-ICGA) in patients without specific risk factors for wound healing complications.

METHODS

Forty-five patients undergoing primary TKA without comorbidities known to impact wound healing and perfusion were prospectively randomized to receive superficial skin closure with one of the following techniques: (1) running subcuticular (3-0 monofilament); (2) vertical mattress (2-0 nylon); or (3) skin staples. Twenty procedures were performed by RTT, 15 by RJS, and 10 by FHS. All surgeons used an anterior skin incision over the medial third of the patella in combination with a median parapatellar arthrotomy. Perfusion was assessed with a LA-ICGA device and software system immediately after closure to quantify fluorescence. Twenty-seven points were assessed immediately after closure in the operating room in each patient (nine along the incision and nine pairs medial and lateral to the incision). Mean incision perfusion was determined from the nine points along the incision with higher values indicating greater blood flow. Mean perfusion impairment was determined by calculating the difference between the nine pairs of surrounding skin and the nine points along the incision with smaller values indicating less perfusion impairment. These parameters were compared with analysis of variance (ANOVA) and subsequent pairwise comparisons with an unadjusted analysis as well as a multivariate analysis that adjusted for age, sex, and body mass index. Patients were followed for a mean of 7 months after surgery (range, 3-12 months) for possible incision-related complications. No patents were lost to followup.

RESULTS

Running subcuticular closure demonstrated the best overall perfusion. Mean incision perfusion in fluorescent units with SD was as follows: running subcuticular, 64 (16); vertical mattress, 32 (18); and staples, 19 (7) (ANOVA p < 0.001). The running subcuticular closure demonstrated the least impairment of perfusion among the closures compared. Mean perfusion impairment was as follows: running subcuticular, 21 (12); vertical mattress, 37 (24); and staples, 69 (27) (ANOVA p < 0.001). All Tukey-adjusted pairwise comparisons from both metrics likewise favored the subcuticular closure (p < 0.001) both before and after adjusting for age, sex, and body mass index. One patient in the vertical mattress cohort experienced a surgical site infection; no other wound-related complications were observed in this study.

CONCLUSIONS

The method of closure can influence skin and soft tissue perfusion after TKA. Running subcuticular closure enables the most physiologic robust blood flow, which may improve wound healing. However, the clinical importance of these findings remains uncertain, because patients in this study were selected because they lacked risk factors for wound healing complications. Studies with this modality in specific patient populations at higher risk for wound complications will be necessary to quantify the clinical advantage of using running subcuticular closure.

Infection prevention in total knee arthroplasty

Periprosthetic joint infections are devastating complications that are difficult and expensive to treat and have a substantial mortality rate. A major goal of modern joint arthroplasty is to minimize these infections. Preoperative factors associated with increased risk of infection include malnutrition, diabetes mellitus, obesity (body mass index >40 kg/m(2)), and rheumatoid arthritis. Administration of appropriate antibiotics before the surgical incision is made is essential to minimize infection. The use of laminar flow rooms, proper skin preparation, limiting operating room traffic, and the use of various wound closure techniques can help to decrease infection rates. Postoperatively, optimal management of indwelling urinary catheters, blood transfusions, and wound drainage also may decrease infection rates.

Determining risk factors for surgical wound dehiscence: a literature review

Postoperative wound healing plays a significant role in facilitating a patient's recovery and rehabilitation. Surgical wound dehiscence (SWD) impacts on mortality and morbidity rates and significantly contributes to prolonged hospital stays and associated psychosocial stressors on individuals and their families. A narrative review of SWD was undertaken on English-only studies between 1945 and 2012 using three electronic databases Ovid CINHAL, Ovid Medline and Pubmed. The aim of this review was to identify predisposing factors for SWD and assessment tools to assist in the identification of at-risk patients. Key findings from the included 15 papers out of a search of 1045 revealed the most common risk factors associated with SWD including obesity and wound infection, particularly in the case of abdominal surgery. There is limited reporting of variables associated with SWD across other surgical domains and a lack of risk assessment tools. Furthermore, there was a lack of clarity in the definition of SWD in the literature. This review provides an overview of the available research and provides a basis for more rigorous analysis of factors that contribute to SWD.

Randomized clinical trial of skin closure by subcuticular suture or skin stapling after elective colorectal cancer surgery

Background

The best suture method to prevent incisional surgical-site infection (SSI) after clean-contaminated surgery has not been clarified.

Methods

Patients undergoing elective colorectal cancer surgery at one of 16 centres were randomized to receive either subcuticular sutures or skin stapling for skin closure. The primary endpoint was the rate of incisional SSI. Secondary endpoints of interest included time required for wound closure, incidence of wound problems, postoperative length of stay, wound aesthetics and patient satisfaction.

Results

A total of 1264 patients were enrolled. The cumulative incidence of incisional SSI by day 30 after surgery was similar after subcuticular sutures and stapled closure (8·7 versus 9·8 per cent respectively; P = 0·576). Comparison of cumulative incidence curves revealed that SSI occurred later in the subcuticular suture group (P = 0·019) (hazard ratio 0·66, 95 per cent c.i. 0·45 to 0·97). Wound problems (P = 0·484), wound aesthetics (P = 0·182) and postoperative duration of hospital stay (P = 0·510) did not differ between the groups; subcuticular sutures took 5 min longer than staples (P &lt; 0·001). Patients in the subcuticular suture group were significantly more satisfied with their wound (52·4 per cent versus 42·7 per cent in the staple group; P = 0·002).

Conclusion

Compared with skin stapling, subcuticular sutures did not reduce the risk of incisional SSI after colorectal surgery. Registration number: UMIN000004001 (http://www.umin.ac.jp/ctr).
