Screw versus staple fixation for Akin osteotomy.

INTRODUCTION: Akin osteotomies are commonly fixed with a screw or staple. Hardware-related symptoms are not uncommon. We compared the outcomes and costs of the two implants. METHODS: We evaluated 74 Akin osteotomies performed in conjunction with first metatarsal osteotomy for hallux valgus. The osteotomy was fixed with a headless compression screw in 39 cases and a staple in 35 cases. We looked at the implant-related complications, removal of metalwork, revision, non-union and cost. Pre- and postoperative hallux valgus interphalangeal (HI) angles and length of the proximal phalanx were measured. RESULTS: There was 100% union, no failure of fixation, no revision surgery and no delayed union in either group. The radiological prominence of screws was significant (p=0.02), but there was no significant difference in soft-tissue irritation (p=0.36) or removal of implants (p=0.49). Two cortical breaches (5.8%) occurred in staple fixation and 4 (10.2%) in screw fixation (not statistically significant (NS), p=0.50). The mean improvement in HI angle was 4.3° with screw fixation and 4.1° with staple fixation (NS, p=0.69). The mean shortening of the proximal phalanx was 2.5mm with screw fixation and 2.3mm with staple fixation (NS, p=0.64). The total cost was £1,925 for staple fixation and £4,290 for screw fixation. CONCLUSIONS: Staple and screw fixation are reproducible modalities with satisfactory outcomes, but screw fixation is expensive. We conclude staple fixation is a cost-effective alternative.

Dermatological surgery: an update on suture materials and techniques. Part 2.

This is the second part of a two-part series summarizing the latest evidence related to suture materials and wound closure techniques in dermatological surgery. We critically appraised evidence focusing on the following consequences of suture choice: scar/cosmesis, pain, patient satisfaction, cost, infection and wound complications. We searched the databases MEDLINE, PubMed and Embase using the keywords 'skin surgery', 'dermatological surgery', 'sutures', 'braided sutures', 'monofilament sutures' and 'antibacterial sutures' to identify relevant English-language articles. This part of the review assesses the evidence for different types of buried sutures, including braided vs. monofilament sutures, longer-absorbing sutures and antibacterial sutures. The majority of trials were noted to be of poor quality, single-centre (thus lacking external validity) and underpowered, which presents challenges in comparing suture techniques in skin surgery. Future large-scale, multicentre, randomized trials are needed, with both surgeon and patient-assessed validated outcomes.

Dermatological surgery: an update on suture materials and techniques. Part 1.

Significant variation exists in the surgical suture materials and techniques used for dermatological surgery. Many wound-closure techniques are now practised, including use of sutures, staples and topical adhesives. The focus of our review article is to summarize the latest evidence relating to suture materials and wound-closure techniques, considering the following areas: scar/cosmesis, pain, patient satisfaction, cost, infection and wound complications. We searched the databases Medline, PubMed and Embase using the keywords 'skin surgery', 'dermatologic surgery', 'sutures', 'suture techniques', 'suturing techniques' and 'surgical techniques' to identify relevant English-language articles. Absorbable superficial sutures may be a preferred alternative to nonabsorbable sutures by both patients and surgeons. Subcuticular sutures may be preferable to simple interrupted sutures for superficial wound closure, and there may also be a role for skin staples in dermatological surgery, particularly on the scalp. However, there remains limited evidence specific to dermatological surgery supporting the use of particular suture materials and suturing techniques. Further high-quality research is required, including multicentre randomized trials with larger cohorts.

A Systematic Review of Suture Technologies in Total Knee Arthroplasty.

Over time, various materials and techniques have been developed for superficial and deep wound closure. However, potential complications, such as infections and dehiscences, can still occur, driving the development of new closure modalities. As wound closure technology continues to advance and change, the need to continuously evaluate the current techniques and materials persists. Therefore, the purpose of this systematic review was to evaluate the current literature on the various closure materials and techniques utilized for total knee arthroplasty. Specifically, we evaluated: 1) closure times; 2) infections and complication rates; as well as 3) costs related to superficial and deep wound closures. Based on the findings from the current literature, barbed suture was associated with significantly shorter closing times in all five studies when compared to interrupted sutures (p<0.05). Additionally, the use of barbed sutures may result in similar postoperative complication rates. Although the cost of an individual barbed suture is potentially higher than the cost of an individual conventional suture, a knotless technique can require a shorter suture length, which might also help decrease costs.

A simple and novel technique for training in microvascular suturing in a rat model.

BACKGROUND: Though microvascular clamps are widely used for anastomosis training, there still have several shortcomings, including the bulging, expensiveness and unavailability due to sterilization. The aim of this study is to introduce a simple and novel microvascular training model without use of microvascular clamps. METHODS: Femoral vessels of Sprague Dawley rats training model were used to evaluate the usefulness of 4-0 silk as a slipknot for performing arterio-arterial and veno-venous microvascular anastomoses. A total of 12 Sprague Dawley rats were randomly assigned to either slipknot group or vascular clamp group. We also assess other endpoints, including ischemic time, patency rate, and clinical features. An additional histological study was performed to compare their immediate traumatic effects on vessel wall. RESULTS: There was no ischemic change or congestive sign in the lower limb after microvascular anastomosis. The total warm ischemic time for the vascular anastomosis was not significantly different. We performed the patency test immediately after microvascular anastomosis and one week after surgery. No intraoperative vascular bleeding was found during these procedures and no thrombosis occurred postoperatively. The histologic damages to occluded area were not significantly different in both groups. CONCLUSION: We demonstrate a microsurgical suture technique performed without any vascular clamp on a rat model. This rat model was designed for training in the technique of microvascular anastomosis. Compared with microvascular clamps, silk slipknot is a cheap, easily available, less space-occupying technique while performing microvascular anastomoses training. This preliminary study provides a simple and effective alternative method for microvascular anastomosis training.

Reoperation following strabismus surgery among Medicare beneficiaries: Associations with geographic region, academic affiliation, surgeon volume, and adjustable suture technique.

Purpose: The objective of this study was to determine the associations of strabismus surgery reoperation rates in a large national database of provider payments with geographic region, practice type and volume, and the availability of adjustable suture technique. Methods: Fee-for-service payments to providers for medicare beneficiaries having strabismus surgery between 2012 and 2015 were retrospectively analyzed to identify reoperations in the same calendar year. The adjustable-suture technique was considered to be available to the patient if the patient's surgeon billed for adjustable sutures. Predictors of reoperation in the same calendar year were determined by multivariable logistic regression. Results: Availability of the adjustable suture technique was not associated with reoperation rate in multivariable analysis among 5971 patients having horizontal muscle surgery (odds ratio, [OR] 0.86, P = 0.29), 2840 patients having vertical muscle surgery (OR 0.98, P = 0.93), or 1199 patients having surgery with scarring or restriction (OR 0.86, P = 0.61). For horizontal surgery, the reoperation rate was higher in academic practices (OR 1.67), as compared with community practices, and in the South (OR 2.85) and West (OR 1.92, all P < 0.001). The reoperation rate was unchanged with surgeons in the lowest-quartile of surgical volume. Among surgeons paid for horizontal surgery, 45% of surgeons in the Northeast, the West, or Florida coded for adjustable sutures, compared with 8% of surgeons elsewhere (P < 0.001). Conclusion: The availability of the adjustable-suture technique was not associated with reoperation rate after strabismus surgery in this large national database. Having surgery by a lower-volume surgeon was not associated with a higher reoperation rate. The reoperation rate was higher when surgery was conducted in an academic practice, or in certain regions of the country. Adjustable sutures are largely a bicoastal practice.

Suture material use and procurement: an audit of a public hospital surgical system in Gauteng, South Africa.

BACKGROUND: Surgical systems are integral to successful, safe and cost effective clinical practice and must balance surgical demands on consumable items and their costs. Suture material is a key consumable resource, and was evaluated in an audit of consumable use and cost as well as the procurement systems within the South African Gauteng public health care sector. AIMS: To determine suture use and cost in the four commonest general surgical procedures - abdominal wall closure, mastectomy, appendicectomy and inguinal hernia repair - in three academic Gauteng hospitals. Performance and availability were evaluated as a secondary aim in suture material use. METHOD: A prospective observational study. Suture use was documented by the surgeon at the time of the procedure and qualitative investigation at relevant hospital departments determined suture material procurement and expenditure. RESULTS: The surgeons in three facilities documented consistent material type and average number of units used; however, in some cases there was a lack of availability of appropriate material and breakage of generic material intraoperatively. There is no consistent and consolidated electronic record-keeping of suture stock and cost in all three hospitals, therefore cost of suture material used was not obtainable. CONCLUSION: Clinical deficiencies in availability and quality of material may have adverse implications for patient health, healthcare costs and budgets through procedure-related complications and should be investigated. There is a lack of communication between the financial management, procurement officers, hospital and theatre stores and theatre staff. It is suggested that clinical protocols and system-based strategies be put in place to manage surgical consumables.

The efficacy and safety of knotless barbed sutures in total joint arthroplasty: a meta-analysis of randomized-controlled trials.

BACKGROUND: The knotless barbed sutures (KBS) are an innovative type of suture that can accelerate the placement of sutures and eliminate knot tying. Whether the KBS are safe and efficient in total joint arthroplasty (TJA) remains controversial. Therefore, we conducted a meta-analysis to evaluate its efficacy and safety. METHODS: Randomized-controlled trials (RCTs) were identified from the PubMed, Embase, and Cochrane Library databases up to October 2017. The Cochrane risk of bias tool was used to assess methodological quality. The statistical analysis was performed with RevMan 5.3.5 software. RESULTS: A total of five RCTs (600 participants) were included in our meta-analysis. The results showed that KBS reduced wound suture time (MD - 4.51, 95% CI - 5.37 to - 3.66, P < 0.00001) and the wound suture cost (MD - 282.63, 95% CI - 445.32 to - 119.95, P < 0.00001), and did not significantly increase the rate of complications (OR 0.77, 95% CI 0.42-1.39, P = 0.13) or intraoperative events (OR 0.86, 95% CI 0.04-17.28, P = 0.92). There were no significant differences in ROM at postoperative 6 weeks and 3 months (MD - 0.74, 95% CI - 4.19 to 2.71, P = 0.67; MD - 0.30, 95% CI - 2.62 to 2.02, P = 0.80; respectively). CONCLUSION: Our findings suggest that KBS are a safe and effective method for TJA. Given the possible biases, adequately powered and better designed studies with longer follow-up are required to reach a firmer conclusion.

Economic and clinical comparison of 2-octyl cyanoacrylate/polymer mesh tape with skin staples in total knee replacement.

OBJECTIVE: To compare economic and clinical outcomes between skin staples and 2-octyl cyanoacrylate plus polymer mesh tape, Dermabond Prineo skin closure system, (SCS) among patients undergoing total knee replacement (TKR). METHOD: Retrospective, observational study using the Premier Healthcare Database, which comprises hospital administrative and billing data for over 700 hospitals in the US. Patients selected for study had an elective hospital admission, with discharge occurring between January 2012 and September 2015, carrying primary ICD-9-CM procedure and diagnosis codes for TKR and osteoarthritis. Patients were classified into two mutually-exclusive groups based on billing records during the index admission: those with billing record(s) for the skin closure system (SCS group); and those with billing record(s) for skin staples (staple group). Primary outcomes were index admission's length of stay (LOS), total hospital costs, and discharge status (skilled nursing facility (SNF)/other versus home/home health-care); exploratory outcomes included operating room time (ORT) during index admission and 30, 60, and 90-day readmissions. The SCS and staple groups were propensity score matched (1:1/nearest neighbour/caliper=0.10) on patient, hospital, and provider characteristics. Multivariable regressions accounting for hospital-level clustering after matching were used to compare outcomes between study groups. RESULTS: Each group comprised 971 patients (1942 total patients; mean age: 65.3 years; female: 63.5%). The groups were generally well-balanced on matching covariates: mean standardised difference calculated across 49 covariates=0.049. Compared with the staple group, the SCS group had statistically significant shorter LOS (2.8 days versus 3.2 days, p=0.002), lower rate of discharge to SNF/other versus home/home health-care (26.4% versus 38.5%, p=0.011), and lower rate of 30, 60, and 90-day readmissions (30-day, 1.8% versus 4.4%, p=0.006; 60-day, 3.0% versus 5.4%, p<0.001; 90-day, 5.4% versus 7.4%, p=0.016). Differences between the groups for other outcomes were not statistically significant. CONCLUSION: Among patients undergoing TKR, use of the SCS was associated with shorter LOS, less resource intensive discharge status, and lower rates of all-cause readmission as compared with skin staples.

Closure of Large Percutaneous Femoral Venous Access Using a Modified "Figure-of-Eight" Suture.

Recent advances in different percutaneous treatments made insertion of large-caliber sheaths in the femoral veins more common. Venous punctures are historically managed by initial manual compression with subsequent application of a compression bandage and bed rest. We describe a modified "figure-of-eight" suture technique for minimizing the risk of accidental puncture of the vein while grabbing the subcutaneous tissue. We examined the safety and feasibility of this technique combined with early mobilization in a real-world setting. We performed a retrospective analysis on 56 consecutive patients undergoing percutaneous mitral valve repair using large femoral venous access. The patient population was heterogeneous and bleeding risk characteristics were common. Bleeding Academic Research Consortium Consensus (BARC)-classifiable bleeding complications occurred in eight patients (14%), BARC of two events or more in five patients (8.9%), and BARC of three or more event in only one patient (1.8%), which is a comparable success rate to large venous access closure with suture-mediated closure devices. No BARC Type 3b or BARC Type 5 bleeding occurred. During routine clinical follow-up, no groin-related problems were reported in all patients. Closure of large femoral venous access using a modified temporary subcutaneous figure-of-eight suture in combination of a light compression bandage and bed rest for 2 to 4 hours provides a safe and low-cost alternative to closure devices for early mobilization.

The Use of Tissue Glue for Circumcision in Children: Systematic Review and Meta-analysis.

OBJECTIVE: To evaluate the efficacy of tissue glue in pediatric circumcision. MATERIALS AND METHODS: A systematic review and meta-analysis of the English literature (1997-2017) was conducted according to the Preferred Reporting Items for Systematic Review and Meta-analyses (PRISMA) statement on children who underwent circumcision with tissue glue. Meta-analysis was conducted using RevMan 5.3, Comprehensive Meta-Analysis 2, and MedCalc 18. P values <.05 were considered significant. RESULTS: The search returned 15 studies for a total of 4567 circumcisions, of which 3045 (66%) were performed with tissue glue. The systematic review indicated that overall complication rates were 4.3% (tissue glue) and 5.9% (sutures). The use of tissue glue was associated with reduced postoperative pain, better cosmetic results, and reduced cost. Meta-analysis showed that there was no difference between the incidence of total postoperative complications (relative risk [RR] 0.86 [95% confidence interval {CI}: 0.62-1.19], P = .36) and wound infection and dehiscence between the 2 groups (RR 0.95 [95% CI: 0.59-1.56], P = .85). Postoperative bleeding and hematoma formation were reduced with the use of tissue glue (RR 0.55 [95% CI: 0.32-0.95], P = .03). Tissue glue also significantly shorten the operative time (mean difference -0.22 [95% CI: -0.39 to -0.05], P = .01). CONCLUSION: The incidence of postoperative bleeding and hematoma formation in pediatric circumcision is reduced with the use of tissue glue. Tissue glue has reduced operative time; furthermore, it might be associated with reduced postoperative pain, less overall cost, and superior cosmetic results.

Looped suture versus stapler device in pediatric laparoscopic appendectomy: a comparative outcomes and intraoperative cost analysis.

BACKGROUND: Appendiceal ligation during pediatric laparoscopic appendectomy (LA) may be performed using looped suture versus stapler. Controversy regarding the utility of either method exists. Clinical outcomes and cost analysis of LA with both methods were compared. METHODS: All pediatric LA were performed from fiscal years 2013 and 2014 by two pediatric surgeons. While one surgeon used looped suture, the other used stapler exclusively. chi-Square tests were performed to analyze associations. RESULTS: Two hundred thirty-eight cases were analyzed where looped suture versus stapler LA was performed in 46% and 54% of patients, respectively. Operating room costs were $317.10 and $707.12/person for looped suture and stapler LA, respectively (P<0.0001). Difference in cost of $390.02/person was attributed solely to ligation type. On bivariate analysis, rate of in-hospital complications, length of stay, return-to-ER and readmission within 30 days did not significantly differ between groups. CONCLUSION: A comparative analysis of looped suture versus stapler device during LA for pediatric appendicitis revealed that postoperative complications, length of stay, ER visits and readmissions were not significantly different. Looped suture LA was significantly more cost efficient than stapler LA. In pediatric appendicitis, appendiceal ligation during LA may be performed safely and cost effectively with looped suture versus stapler. TYPE OF STUDY: Cost effectiveness LEVEL OF EVIDENCE: III.

Low cost endo-loop for rural surgeons.

Readymade endo-loops can make laparoscopic surgery convenient and faster. Commercially made endo-loops are expensive. We describe a method of making low-cost endo-loops from materials available in the operating room.

Cost-Effective Surgical Management of Liver Disease Amidst a Financial Crisis.

BACKGROUND: Intraoperative use of specialized equipment and disposables contributes to the increasing cost of modern liver surgery. As a response to the recent severe financial crisis in our country we have employed a highly standardized protocol of liver resection that minimizes intraoperative and postoperative costs. Our goal is to evaluate cost-effectiveness of this protocol. STUDY DESIGN: We evaluated retrospectively all patients who underwent open hepatic resections for 4 years. All resections were performed by the same surgical team under selective hepatic vascular exclusion, i.e., occlusion of the hepatoduodenal ligament and the major hepatic veins, occasionally combined with extrahepatic ligation of the ipsilateral portal vein. Sharp parenchymal transection was performed with a scalpel and hemostasis was achieved with sutures without the use of energy devices. In each case we performed a detailed analysis of costs and surgical outcomes. RESULTS: Our cohort included 146 patients (median age 63 years). 113 patients were operated for primary or metastatic malignancies and 33 for benign lesions. Operating time was 121 ± 21 min (mean ± SD), estimated blood loss was 310 ± 159 ml (mean ± SD), and hospital stay was 7 ± 5 days (mean ± SD). Six patients required admission in the ICU postoperatively. 90-day mortality was 2.74 %, and 8.9 % of patients developed grade III/IV postoperative complications (Clavien-Dindo classification). Total in-hospital cost excluding physician fees was 6987.63 ± 3838.51 USD (mean ± SD). CONCLUSIONS: Our analysis suggests that, under pressing economic conditions, the proposed surgical protocol can significantly lessen the financial burden of liver surgery without compromising patient outcomes.

Efficacy of triclosan-coated sutures for reducing risk of surgical site infection in adults: a meta-analysis of randomized clinical trials.

BACKGROUND: Surgical site infection (SSI) is the third most frequent type of nosocomial infections. Triclosan-coated sutures are often used to reduce the risk of SSI, but studies examining this have given conflicting results. Therefore, this meta-analysis was performed to assess the efficacy of triclosan-coated sutures for reducing risk of SSI in adults. METHODS: PubMed, EMBASE, Google Scholar, and ClinicalTrials.gov were searched to identify randomized clinical trials evaluating triclosan-coated sutures for preventing SSI on patients 18 y or older. RESULTS: Thirteen randomized clinical trials involving 5256 participants were included. Triclosan-coated sutures were associated with lower risk of SSI than uncoated sutures across all surgeries (risk ratio [RR] 0.76, 95% confidence interval [CI] 0.65-0.88, P < 0.001). Similar proportions of patients experienced wound dehiscence with either type of suture (RR 0.97, 95% CI 0.49-1.89, P = 0.92). Subgroup analysis showed lower risk of SSI with triclosan-coated sutures in abdominal surgeries (RR 0.70, 95% CI 0.50-0.99, P = 0.04) and group with prophylactic antibiotic (RR 0.79, 95% CI 0.63-0.99, P = 0.04). However, such risk reduction was not observed in cardiac surgeries, breast surgeries, or group without prophylactic antibiotic. CONCLUSIONS: Triclosan-coated sutures can decrease the incidence of SSI in abdominal surgeries and might not interfere with wound healing process. Nevertheless, further studies are needed to examine whether triclosan-coated sutures are effective at preventing SSI in non-abdominal surgeries and to further study the interaction of antibiotic prophylaxis with triclosan-coated sutures.

Review of anterior cruciate ligament reconstruction cost variance within a regional health care system.

BACKGROUND: Examination of value in health care has become a national priority in the United States. Regional variation in health care costs is an area of focus among national policy experts. Procedural cost data can be used to provide physicians with information to evaluate costs and value. PURPOSE: To perform a cost review for anterior cruciate ligament (ACL) surgery to document the degree of variation in costs for ACL reconstruction. STUDY DESIGN: Economic and decision analysis; Level of evidence, 4. METHODS: A procedural cost review was performed for isolated ACL reconstructions within a 22-surgeon, 7-hospital system. Five consistent cost categories under the influence of the surgeon were identified and were analyzed for cost variation among surgeons: tibial fixation, femoral fixation, graft choice, sutures, and tools or disposable instruments. RESULTS: For these 5 categories, the total costs to perform an ACL reconstruction (in 2013 US dollars) ranged from $392.80 to $4670.31, a difference of $4277.51 and a mean of $2039.09. Tibial fixation costs ranged from $95.00 to $760.00 (mean, $293.52). Femoral fixation ranged from $95.00 to $865.00 (mean, $367.14). The graft cost ranged from $1275.00 to $2545.75 (mean, $1976.43). Suture prices for each individual suture varied from $1.19 to $46.00 (mean, $18.26). Tools and disposable supplies ranged from $40.10 to $2136.00 (mean, $452.33). CONCLUSION: There were substantial differences in ACL reconstruction costs in the implant and disposable instruments categories. As health systems and physicians collaborate to improve health care quality and value for patients, information on cost variation will be important. Rational variation in health care cost is appropriate, reflecting variation due to the unique requirements of procedures and patient-centered care. Irrational variations in procedural costs are those that do not add additional value.

Cost-benefit analysis of outcomes from the use of fibrin sealant for fixation of skin grafts in small-size burns compared to staples as historical controls: a retrospective review.

INTRODUCTION: Historically, split-thickness skin grafts have been fixed onto the recipient site by suture and/or staples. Fibrin sealants have become available for the fixation in the past 10 years. Fibrin sealants have been shown to be at least as effective as staples, and recent reports show them to cause less pain. However, the product is much more expensive than traditional suture and/or staple fixation. The cost-benefit ratio of sealant has not yet been proven. METHODS: A review of charts for 202 consecutive patients was undertaken for patients with burns that were less than 10% total body surface area (TBSA) that underwent excision and grafting using fibrin sealant at the regional burn center. A historical control comprising 48 consecutive patients with burns that were less than 10% TBSA that underwent excision and grafting using staples as the only means of fixation was used for comparison. Demographics (such as age, weight, and sex), personal history of tobacco use, previous diagnosis of diabetes, type and depth of burn, TBSA, area of grafting, graft and donor locations, mesh type, rate of hematomas, rate of graft loss, rate of complete closure at 1 month, and time to discharge after surgery were recorded for each patient in both cohorts. The data were compared and statistical analysis performed for graft loss complications and number of days until the patient could be discharged home with outpatient wound care. RESULTS: Use of fibrin sealants has resulted in statistically significant lower rates of loss of graft at our institution. Additionally, a decrease in the number of days until discharge to outpatient wound care of nearly 2 days produced a lower cost of care in patients with less than 10% TBSA undergoing excision and grafting. CONCLUSIONS: The use of fibrin sealants allows for fewer graft loss complications and earlier discharge in patients who have burns that are less than 10% TBSA. This decrease in hospital days results in savings, although this difference is not statistically significant.
