An Outcomes Review of 330 Sternal Wound Reconstructions: Timing of Closure Does Make a Difference.

BACKGROUND: Sternal wound infection and dehiscence following cardiac surgery remain difficult clinical problems with high morbidity. Older classification systems regarding timing to reconstruction do not take into account recent improvements in critical care, wound vacuum-assisted closure use, or next-generation antibiotic therapies, which may prolong time to reconstruction. METHODS: Records of patients undergoing sternal wound reconstruction performed by the senior author (J.A.A.) from 1996 to 2018 at a high-volume cardiac surgery center were reviewed. Indications included sternal wound infection or dehiscence. All patients underwent single-stage removal of hardware, débridement, and flap closure. Patients were divided into two groups based on timing of wound closure after cardiac surgery: less than 30 days or greater than or equal to 30 days. RESULTS: Of the 505 patients identified during the study period, 330 had sufficient data for analysis. Mean time to sternal wound surgery was 15.7 days in the early group compared to 64.4 days (p < 0.01) beyond 30 days. Postdébridement cultures were positive in 72 percent versus 62.5 percent of patients (p = 0.11), whereas rates of postoperative infection were significantly higher in the delayed group: 1.9 percent versus 9.5 percent (p < 0.01). Partial wound dehiscence rates were also higher after 30 days (1.9 percent versus 11.3 percent; p < 0.01), whereas total length of stay was decreased. Use of wound vacuum-assisted closure was significantly associated with reconstruction beyond 30 days (p < 0.01). CONCLUSIONS: Although performing sternal wound reconstruction more than 30 days after initial cardiac surgery was associated with a shorter overall hospital length of stay and higher extubation rates in the operating room, these patients also had elevated postoperative infection and wound complication rates. The authors thus recommend not delaying definitive surgical reconstruction when possible. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Pre-tracheotomy for Potentially Emergent Airway Scenarios: Indications and Outcomes.

OBJECTIVES/HYPOTHESIS: Airway access in the setting of unsuccessful ventilation and intubation typically involves emergent cricothyrotomy or tracheotomy, procedures with associated significant risk. The potential for such emergent scenarios can often be predicted based on patient and disease factors. Planned tracheotomy can be performed in these cases but is not without its own risks. We previously described a technique of pre-tracheotomy or exposing the tracheal framework without entering the trachea, as an alternative to planned tracheostomy in such cases. In this way, a tracheotomy can be easily completed if needed, or the wound can be closed if it is not needed. This procedure has since been used in an array of indications. We describe the clinical situations where pre-tracheotomy was performed as well as subsequent patient outcomes. METHODS: Retrospective series of patients undergoing a pre-tracheotomy from 2015 to 2020. Records were reviewed for patient characteristics, indication, whether the procedure was converted to tracheotomy or closed at the bedside, and any post-procedural complications. RESULTS: Pre-tracheotomy was performed in 18 patients. Indications included failed extubation after head and neck reconstruction, subglottic stenosis, laryngeal masses, laryngeal edema, thyroid masses, and an oropharyngeal bleed requiring operative intervention. Tracheotomy was avoided in 10 patients with wound closed at the bedside; procedure was converted to tracheotomy in the remaining eight. There were no complications. Indications for conversion included failed extubation, intraoperative hemorrhage, significant stridor with dyspnea, and inability to ventilate. CONCLUSION: Pre-tracheotomy offers simplified airway access and provides a valuable option in scenarios where tracheotomy may, but not necessarily, be needed.

Cephalad-caudad versus transverse blunt expansion of the low transverse hysterotomy during cesarean delivery decreases maternal morbidity: a meta-analysis.

OBJECTIVE: Cesarean delivery is the most prevalent surgical procedure worldwide, reaching approximately 29.7 million cases in 2015. It is directly associated with an increased risk of maternal and neonatal morbidity rates in the absence of malpresentation. Several techniques have been investigated, and there is evidence that cephalad-caudad expansion of the uterine incision might be associated with improved maternal outcomes compared with traditional transverse blunt expansion. The purpose of this meta-analysis was to evaluate the impact of cephalad-caudad expansion on adverse maternal outcomes, including intraoperative blood loss, risk of uterine vessel injury, and tearing of the lower uterine segment. DATA SOURCES: We searched Medline, Scopus, the Cochrane Central Register of Controlled Trials, Google Scholar, and Clinicaltrials.gov databases from inception to January 2021. STUDY ELIGIBILITY CRITERIA: Randomized controlled trials that assessed the impact of the cephalad-caudad blunt expansion of the low transverse uterine incision during cesarean delivery rather than those of transverse blunt expansion were selected for inclusion. METHODS: Effect sizes were calculated with the Hartung-Knapp-Sidik-Jonkman random-effects model in R. Trial sequential analysis was performed to evaluate the adequacy of sample sizes. RESULTS: Cephalad-caudad blunt expansion of the uterine incision was associated with a lower prevalence of unintended incision extension (relative risk, 0.62; 95% confidence interval, 0.45-0.86) and uterine vessel injury (relative risk, 0.55; 95% confidence interval 0.41-0.73). However, these complications were not accompanied by the increased need for additional suture placement (relative risk, 0.62; 95% confidence interval, 0.31-4.12) or transfusion rates (relative risk, 0.75; 95% confidence interval, 0.28-2.03). Similarly, the intraoperative duration was comparable with cases treated with transverse blunt expansion (mean difference = -0.45 minutes; 95% confidence interval -2.12 to 1.21) and the risk of intentional incision extension in the form of an inverted T (relative risk, 0.38; 95% confidence interval, 0.09-1.52). Trial sequential analysis revealed that the required sample size was reached in the unintended incision extension and uterine vessel injury outcomes. CONCLUSION: The findings of our study suggested that cephalad-caudad blunt expansion of the uterine incision is superior to transverse expansion in terms of reducing unintended incision extension and uterine vessel injury.

Shifting and reducing breathing disturbance in patients with very severe obstructive sleep apnea by modified Z-palatoplasty with one-layer closure in one-stage multilevel surgery.

Very severe obstructive sleep apnea (OSA) with apnea-hypopnea index (AHI) ≥ 60 events/h differs in several areas from OSA with other severities, including having a low-level daytime partial pressure of oxygen and residual on-CPAP (continuous positive airway pressure) AHIs greater than 20/h. Patients with very severe OSA show narrow retroglossal space and confined framework, which is difficult to be enlarged via conventional Uvulopalatopharyngoplasty (UPPP) surgery, resulting in poor response to non-framework surgeries. Our latest report showed efficacy and efficiency for subjects undergoing modified Z-palatoplasty (ZPP) with one-layer closure in a one-stage multilevel surgery. It is unclear whether and how this procedure could help patients with very severe OSA characterized with confined framework. From Mar. 2015 to May 2018, we enrolled 12 patients with very severe OSA receiving one-stage multi-level surgery with modified ZPP with one-layer closure, CO2 laser partial tongue-base glossectomy, and bilateral septomeatoplasty. Our results show that the surgery reduced AHI from 73.8 ± 10.7 to 30.8 ± 23.2 events/h and achieved a mean AHI reduction of 58.3% (p < 0.001 against 0 reduction or no surgery). The surgery shifted components of the breathing disturbances. It reduced more apnea than hypopnea and might convert some apnea to hypopnea.

Intersphincteric Exploration With Ligation of Intersphincteric Fistula Tract or Attempted Closure of Internal Opening for Acute Anorectal Abscesses.

BACKGROUND: Acute anorectal abscesses of cryptoglandular origin are commonly managed by incision and drainage, which results in fistula development in up to 73% of cases, requiring subsequent definitive fistula surgery. However, given that fistula tracts may already be present at the initial presentation, primary closure of the tract as secondary prevention of fistula formation, using ligation of intersphincteric fistula tract, may be useful. OBJECTIVE: This study aims to examine the feasibility and outcomes of performing intersphincteric exploration with ligation of intersphincteric fistula tract or attempted closure of internal opening for acute anorectal abscesses. DESIGN: This is a retrospective study of patients with acute anorectal cryptoglandular abscesses who underwent surgery between January 2014 and December 2016. SETTINGS: The patients were treated at a tertiary referral center in Thailand. PATIENTS: Eighty-six patients with acute anorectal abscesses without previous surgery were included. INTERVENTIONS: Intersphincteric dissection was performed. Further surgical intervention was dependent on the intersphincteric findings. MAIN OUTCOME MEASURE: The main outcome measure was the 90-day healed rate. RESULTS: Of the 86 patients, 3 had low intersphincteric abscesses, 26 had low transsphincteric abscesses, 25 had anterior high transsphincteric abscesses, 27 had posterior high transsphincteric abscesses, and 5 had high intersphincteric abscesses. Ligation of intersphincteric fistula tract was successfully performed in 66 patients with an identifiable intersphincteric tract. Intersphincteric exploration with attempted closure of the internal opening was performed in the remaining 20 patients. The success rates were 86% and 70%. Unidentified internal opening and intersphincteric pathology were risk factors for nonhealing. No patients reported fecal incontinence postoperatively. LIMITATIONS: The limitation of this study is its retrospective nature and that all operations were performed by a single surgeon; therefore, the results may vary according to the individual surgeon's expertise. CONCLUSIONS: Fistula tract formation was found in most cases of acute anorectal abscesses. Definitive surgery using this strategy provides promising results.

EXPLORACIN INTERESFINTRICA CON LIGADURA DEL TRAYECTO EN LA FSTULA INTERESFINTRICA O INTENTO DE CIERRE DEL ORIFICIO INTERNO EN ABSCESOS ANORRECTALES AGUDOS: ANTECEDENTES:Los abscesos anorrectales agudos de origen criptoglandular, comúnmente se manejan mediante incisión y drenaje, lo que resulta en el desarrollo de una fístula hasta en un 73% de los casos, requiriendo posteriormente cirugía definitiva de la fístula. Sin embargo, dado que los trayectos de la fístula ya pueden estar inicialmente presentes, puede ser útil el cierre primario del trayecto, como prevención secundaria en la formación de la fístula, mediante la ligadura del trayecto de la fístula interesfintérica.OBJETIVO:El estudio tiene como objetivo, examinar la viabilidad y los resultados en realizar exploración interesfintérica, con ligadura del trayecto de fístula interesfintérica o intento de cierre del orificio interno para abscesos anorrectales agudos.DISEÑO:Se trata de un estudio retrospectivo de pacientes con abscesos criptoglandulares anorrectales agudos, que fueron operados entre enero de 2014 y diciembre de 2016.AJUSTES:Los pacientes fueron tratados en un centro de referencia terciario en Tailandia.PACIENTES:Se incluyeron 86 pacientes con abscesos anorrectales agudos, sin cirugía previa.INTERVENCIONES:Se realizó disección interesfintérica. La intervención quirúrgica adicional dependió de los hallazgos interesfintéricos.PRINCIPALES MEDIDAS DE RESULTADO:La principal medida de resultado, fue la tasa de cicatrización a 90 días.RESULTADOS:De los 86 pacientes, hubo 3 abscesos interesfintéricos bajos, 26 abscesos transesfintéricos bajos, 25 abscesos transesfintéricos anteriores altos, 27 abscesos transesfintéricos posteriores altos y 5 abscesos interesfintéricos altos. La ligadura del tracto de la fístula interesfintérica, con tracto interesfintérico identificable, se realizó con éxito en 66 pacientes. Se realizó exploración interesfintérica, con intento de cierre del orificio interno en los 20 pacientes restantes. Las tasas de éxito fueron 86% y 70% respectivamente. Orificio interno no identificado y patología interesfintérica, fueron factores de riesgo para la falta de cicatrización. Ningún paciente reportó incontinencia fecal posoperatoria.LIMITACIONES:La limitación de este estudio, es su naturaleza retrospectiva y que todas las operaciones fueron realizadas por un solo cirujano, por lo tanto, los resultados pueden variar según la experiencia de cada cirujano.CONCLUSIONES:En la mayoría de los casos de abscesos anorrectales agudos, se encontró formación de trayectos fistulosos. La cirugía definitiva con esta estrategia, proporciona resultados prometedores. Consulte Video Resumen en http://links.lww.com/DCR/B451.

Assessment of the Risk and Economic Burden of Surgical Site Infection Following Colorectal Surgery Using a US Longitudinal Database: Is There a Role for Innovative Antimicrobial Wound Closure Technology to Reduce the Risk of Infection?

BACKGROUND: Colorectal surgical procedures place substantial burden on health care systems because of the high complication risk, of surgical site infections in particular. The risk of surgical site infection after colorectal surgery is one of the highest of any surgical specialty. OBJECTIVE: The purpose of this study was to determine the incidence, cost of infections after colorectal surgery, and potential economic benefit of using antimicrobial wound closure to improve patient outcomes. DESIGN: Retrospective observational cohort analysis and probabilistic cost analysis were performed. SETTINGS: The analysis utilized a database for colorectal patients in the United States between 2014 and 2018. PATIENTS: A total of 107,665 patients who underwent colorectal surgery were included in the analysis. MAIN OUTCOME MEASURES: Rate of infection was together with identified between 3 and 180 days postoperatively, infection risk factors, infection costs over 24 months postoperatively by payer type (commercial payers and Medicare), and potential costs avoided per patient by using an evidence-based innovative wound closure technology. RESULTS: Surgical site infections were diagnosed postoperatively in 23.9% of patients (4.0% superficial incisional and 19.9% deep incisional/organ space). Risk factors significantly increased risk of deep incisional/organ-space infection and included several patient comorbidities, age, payer type, and admission type. After 12 months, adjusted increased costs associated with infections ranged from $36,429 to $144,809 for commercial payers and $17,551 to $102,280 for Medicare, depending on surgical site infection type. Adjusted incremental costs continued to increase over a 24-month study period for both payers. Use of antimicrobial wound closure for colorectal surgery is projected to significantly reduce median payer costs by $809 to $1170 per patient compared with traditional wound closure. LIMITATIONS: The inherent biases associated with retrospective databases limited this study. CONCLUSIONS: Surgical site infection cost burden was found to be higher than previously reported, with payer costs escalating over a 24-month postoperative period. Cost analysis results for adopting antimicrobial wound closure aligns with previous evidence-based studies, suggesting a fiscal benefit for its use as a component of a comprehensive evidence-based surgical care bundle for reducing the risk of infection.

EVALUACIÓN DEL RIESGO Y LA CARGA ECONÓMICA DE LA INFECCIÓN DEL SITIO QUIRÚRGICO DESPUÉS DE UNA CIRUGÍA COLORRECTAL UTILIZANDO UNA BASE DE DATOS LONGITUDINAL DE EE.UU.: ¿EXISTE UN PAPEL PARA LA TECNOLOGÍA INNOVADORA DE CIERRE DE HERIDAS ANTIMICROBIANAS PARA REDUCIR EL RIESGO DE INFECCIÓN?: Los procedimientos quirúrgicos colorrectales suponen una carga considerable para los sistemas de salud debido al alto riesgo de complicaciones, particularmente las infecciones del sitio quirúrgico. El riesgo de infección posoperatoria del sitio quirúrgico colorrectal es uno de los más altos de cualquier especialidad quirúrgica.El propósito de este estudio fue determinar la incidencia, el costo de las infecciones después de la cirugía colorrectal y el beneficio económico potencial del uso del cierre de la herida con antimicrobianos para mejorar los resultados de los pacientes.Análisis retrospectivo de cohorte observacional y análisis de costo probabilístico.El análisis utilizó la base de datos para pacientes colorrectales en los Estados Unidos entre 2014 y 2018.Un total de 107,665 pacientes sometidos a cirugía colorrectal.Se identificó una tasa de infección entre 3 y 180 días después de la operación, los factores de riesgo de infección, los costos de infección durante 24 meses posteriores a la operación por tipo de pagador (pagadores comerciales y Medicare), y los costos potenciales evitados por paciente utilizando una tecnología innovadora de cierre de heridas basada en evidencias.Infecciones del sitio quirúrgico, diagnosticadas postoperatoriamente en el 23,9% de los pacientes (4,0% incisional superficial y 19,9% incisional profunda / espacio orgánico). Los factores de riesgo aumentaron significativamente el riesgo de infección profunda por incisión / espacio orgánico e incluyeron comorbilidades selectivas del paciente, edad, tipo de pagador y tipo de admisión. Después de 12 meses, el aumento de los costos asociados con las infecciones varió de $ 36,429 a $ 144,809 para los pagadores comerciales y de $ 17,551 a $ 102,280 para Medicare, según el tipo de infección del sitio quirúrgico. Los costos incrementales ajustados continuaron aumentando durante un período de estudio de 24 meses para ambos pagadores. Se prevé que el uso del cierre antimicrobiano de la herida para la cirugía colorrectal reducirá significativamente los costos medios del pagador en $ 809- $ 1,170 por paciente en comparación con el cierre tradicional de la herida.Los sesgos inherentes asociados a las bases de datos retrospectivas limitaron este estudio.Se encontró que la carga del costo de la infección del sitio quirúrgico es mayor que la reportada previamente, y los costos del pagador aumentaron durante un período postoperatorio de 24 meses. Los resultados del análisis de costos para la adopción del cierre de heridas antimicrobianas se alinean con estudios previos basados en evidencia, lo que sugiere un beneficio fiscal para su uso como componente de un paquete integral de atención quirúrgica basada en evidencia para reducir el riesgo de infección.

Management of Gustilo-Anderson Type II and IIIA Open Long Bone Fractures in Children: Which Wounds Require a Second Washout?

INTRODUCTION: Timing of wound closure in pediatric Gustilo-Anderson grade II and IIIA open long bone fracture remain controversial. Our aims are (1) to determine the proportion of patients with these fractures whose wounds can be treated with early primary wound closure (EPWC); (2) to compare the complication rates between EPWC and delayed wound closure (DWC); and (3) to determine factors associated with higher likelihood of undergoing DWC. PATIENTS AND METHODS: At a level-1 pediatric trauma center, 96 patients (younger than 18 y) who sustained Gustilo-Anderson grade II and IIIA open long bone fractures (humerus, radius, ulnar, femur, or tibia) within a 10-year period (2006-2016) were included for this study. Decision for EPWC versus DWC was at the discretion of the attending surgeon at time of initial surgery. Data collection was via retrospective review of charts and radiographs. Particular attention was paid to the incidence of return to operating room rate, nonunion, compartment syndrome, and infection. Median follow-up duration was 7.5 months (interquartile range: 3.6 to 25.3 mo). All patients were followed-up at least until bony union. RESULTS: Overall, 81% of patients (78/96) underwent EPWC. Of the grade II fractures, 86% underwent EPWC. Four patients (5%) in the EPWC group and 1 patient (6%) in the DWC group had at least 1 complication. When controlling for mechanism of injury, Gustilo-Anderson fracture type and age, there was no difference in rate of complications between the EPWC and the DWC groups. Grade IIIA fractures and being involved in a motor vehicle accident were factors associated with a higher likelihood of undergoing DWC. CONCLUSION: The majority of grade II and IIIA pediatric long bone fractures may be safely treatable with EPWC without additional washouts. Future prospective research is required to further define the subgroups that can benefit from DWC. LEVEL OF EVIDENCE: Level IV-therapeutic, case cohort study.

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.

Comparison of the modified direct closure method and skin grafting for wounds at the anterolateral thigh flap donor site.

OBJECTIVE: This study was performed to compare the modified direct closure method and traditional skin grafting for wounds at the anterolateral thigh (ALT) flap donor site. METHODS: Among 29 consecutive patients with wounds at the ALT flap donor site, 14 underwent the modified direct closure method (MDC group) and 15 underwent traditional skin grafting (SG group). The operative time, follow-up time, complications, Vancouver Scar Scale (VSS) score, and Scar Cosmesis Assessment and Rating (SCAR) score of the two groups were statistically analyzed. RESULTS: The mean follow-up times in the MDC and SG group were 16.1 and 16.7 months, respectively. Two patients showed partial skin necrosis after skin grafting, but the remaining patients' wounds healed uneventfully. The operative time in the MDC group was an average of about 64 minutes shorter than that in the SG group. The average VSS and SCAR scores in the MDC group were 2.1 and 3.0 points lower, respectively, than those in the SG group. CONCLUSIONS: Compared with traditional skin grafting, the modified direct closure method is more efficient for repair of wounds at the ALT flap donor site because of its shorter operative time, better postoperative appearance of the donor site, and higher patient satisfaction.

Hem-o-lok clips versus intracorporeal knotting for the closure of the appendix stump in laparoscopic appendectomy: A prospective randomized study.

BACKGROUND: In this study, we aimed to evaluate the superiority of intracorporeal sutures and Hem-o-lok clips about efficiency, reliability and cost. METHODS: We performed laparoscopic surgery for acute appendicitis in this study. Appendiceal stump was closed by Hem-o-lok clips (Group I) and intracorporeal knotting (Group II) in a randomized manner. Groups were compared for demographic data (age, sex, body mass index, American Society of Anesthesiologists score) operation time, total cost, 2.6.12.24.hours and 7th day pain score. RESULTS: Demographic data, such as age, gender and BMI, were similar between groups (p>0.05). There was no significant difference between the groups concerning peroperative and postoperative complications (p>0.05). No postoperative nausea, vomiting, ileus and intraabdominal abscess were observed in patients. There was no significant difference between the groups about duration of operation, length of hospital stay and cost analysis (p>0.05). There was no significant difference in pain scores of groups. The effect of the operation type on pain scores was not statistically significant (p>0.05). CONCLUSION: This study showed that both intracorporeal knotting and Hem-o-loc clips were effective, reliable and similar cost-effective in laparoscopic appendectomy. The decision should be based on the surgeon's experience.

Evaluation of the Possible Risk Factors on Bronchial Closure Techniques for Bronchopleural Fistula after Lung Resection.

BACKGROUND: Broncho-pleural fistula (BPF) can occur after pulmonary resections as a complication with high morbidity and mortality rates. AIM: In the present study, we analyzed the relation between the possible risk factors and the two major bronchial closure techniques for BPF after lung resections, and the management methods of BPF. MATERIALS AND METHODS: A total of 26 cases detected and managed with BPF diagnosis in our clinic between September 2005 and September 2017 were evaluated retrospectively. The cases were divided into two groups: Group 1 (n=14); bronchial closure performed manually and Group 2 (n=12) bronchial closure with stapler. We analyzed cases for age, gender, body mass index, pulmonary function tests, time to fistula, total protein/albumin level, length of hospital stay, bronchial stump distance, presence of bronchial stump coverage, and the mean survivals. RESULTS: Twenty-three of the cases were males (88.5%) with a mean age of 60.03±8.7 years (range 38-73). While BPF was detected in twenty-three (88.5%) of the cases after pneumonectomy, three (11.5%) of them were after lobectomy. There was no statistically significant correlation between the two groups in gender, age, BMI, preoperative FEV1, time to fistula, total protein/albumin level, length of hospital stay, bronchial stump distance, and presence of bronchial stump coverage (chi-square test, p>0.05). As a result of the applied Kaplan-Meier analysis, we found no statistically significant difference in the mean survival rates between the two groups (p>0.05). CONCLUSIONS: Broncho-pleural fistulas still remains a major challenge. Although there is no statistical relationship between bronchial closure techniques and possible risk factors in our study, patients should be assessed in terms of possible risk factors. The management strategy for BPF varies according to individual patients' clinical condition, the size of the fistula, and development time.

Darier and Ferrand's dermatofibrosarcoma: A carcinologic and cosmetologic challenge in a low-income country.

INTRODUCTION: Dermatofibrosarcoma (DFS) is a common dermic sarcoma. It is a local malignant tumor occurring in young adults. The recurrence potential justifies an R0-type surgery with a three centimeters margin. We report our experience of the management of locally advanced DFS by resection and reconstructive surgery. METHODS: It is an ongoing descriptive study spanned from June 2005 to December 2018. We included all DFS cases treated by curative resection and reconstruction. A total of eight cases of DFS among 108 soft tissue sarcomas were studied. All patients were males. The mean age was 41.8 years [32-60]. Carcinologic results, cosmetic results, and outcomes were analyzed. RESULTS: R0-type resection was performed in six cases. In two cases, the resection was R1-type and resulted in amputation. In four cases, it was an iterative surgery. Average desease duration was 4 years [1-8]. Reconstructive surgery was needed for wound closure in six cases. Wounds healed in 28 days [18-90]. Outcomes showed hyperchromic keloid scars (N=2) at the trunk localization. CONCLUSION: DFS is a common cancer with a good outcome if managed earliest. Delayed diagnoses and inadequate first-time surgery led to tumor extension and recurrences. Locally advanced tumors management needs extensive resections and reconstructive surgery. In addition to surgery, Imatinib and radiotherapy improve outcomes, but are not available in our context.

Treatment of Perianal Fistulas in Crohn's Disease, Seton Versus Anti-TNF Versus Surgical Closure Following Anti-TNF [PISA]: A Randomised Controlled Trial.

BACKGROUND AND AIMS: Most patients with perianal Crohn's fistula receive medical treatment with anti-tumour necrosis factor [TNF], but the results of anti-TNF treatment have not been directly compared with chronic seton drainage or surgical closure. The aim of this study was to assess if chronic seton drainage for patients with perianal Crohn's disease fistulas would result in less re-interventions, compared with anti-TNF and compared with surgical closure. METHODS: This randomised trial was performed in 19 European centres. Patients with high perianal Crohn's fistulas with a single internal opening were randomly assigned to: i] chronic seton drainage for 1 year; ii] anti-TNF therapy for 1 year; and iii] surgical closure after 2 months under a short course anti-TNF. The primary outcome was the cumulative number of patients with fistula-related re-intervention[s] at 1.5 years. Patients declining randomisation due to a specific treatment preference were included in a parallel prospective PISA registry cohort. RESULTS: Between September 14, 2013 and November 20, 2017, 44 of the 126 planned patients were randomised. The study was stopped by the data safety monitoring board because of futility. Seton treatment was associated with the highest re-intervention rate [10/15, versus 6/15 anti-TNF and 3/14 surgical closure patients, p = 0.02]. No substantial differences in perianal disease activity and quality of life between the three treatment groups were observed. Interestingly, in the PISA prospective registry, inferiority of chronic seton treatment was not observed for any outcome measure. CONCLUSIONS: The results imply that chronic seton treatment should not be recommended as the sole treatment for perianal Crohn's fistulas.

Predictors of Urinary Retention After Vesicovaginal Fistula Surgery: A Retrospective Case-Control Study.

OBJECTIVE: The objective of this study is to determine the predictors for urinary retention after vesicovaginal fistula surgery. METHODS: This was a retrospective case-control study of women who underwent vesicovaginal fistula repair between January 2014 and December 2017 at the Fistula Care Centre in Lilongwe, Malawi. Cases were defined as patients with documented urinary retention, defined as a postvoid residual that is 50% greater than the total void of at least 100 mL. The cases and controls were matched by the 3 components of the Goh classification system in a ratio of 1:5. Univariate analysis was used to detect differences between demographic, clinical characteristics, and operative techniques between cases and control. Logistic regression analysis was performed for estimation of odds ratios (ORs). RESULTS: There were no statistically significant differences between the 40 cases and 187 controls, when comparing age, gravidity, parity, body mass index, and length of postoperative catheterization. The median amount of postvoid residual noted at the time of diagnosis was 240 mL (range, 55-927 mL). Odds for urinary retention was 3 times higher among those with vertical closure than patients with horizontal closure of the bladder (OR, 2.91; 95% confidence interval, 1.35-6.20). Patients with prior fistula repairs were significantly less likely to develop urinary retention compared to those receiving surgery for the first time (OR, 0.27; 95% confidence interval, 0.10-0.67). CONCLUSIONS: Vertical closure of the bladder and patients without a history of prior fistula repairs are predictors for developing urinary retention after fistula repair surgery.

An Evaluation of Fascial Closure Techniques in Open Ventral Hernia Repair: Practice Patterns and Short-Term Outcomes.

The best method for fascial closure during hernia repair remains unknown. This study evaluates the impact of fascial closure techniques on short-term outcomes. All patients undergoing open ventral hernia repair were queried using the Americas Hernia Society Quality Collaborative database. Analysis was stratified by suture type (absorbable and permanent) and technique (figure-of-eight, running, and interrupted). Outcome measures included SSI, surgical site occurrence (SSO), SSO requiring intervention, recurrence rate, and quality of life. Descriptive statistics and logistic regression were used. The study included 6544 patients. Two-thirds of surgeons closed fascia during ventral hernia repair with absorbable suture and one-third with permanent suture. In the absorbable group, 17 per cent used figure-of-eight, 46 per cent running, and 4 per cent interrupted suture. In the permanent group, 13 per cent used figure-of-eight, 8 per cent running, and 11 per cent interrupted suture. There was no significant association between SSO and closure technique (P = 0.2). However, SSO and suture type were significant (P < 0.001) with the odds of SSO for closure with absorbable suture being 62 per cent higher than the odds of permanent. Fascial closure technique and suture type had no significant association (P > 0.5) with SSI, SSO requiring intervention, hernia recurrence rate, or HerQLes or NIH PROMIS 3a scores at 30 days or 6 months. Fascial closure technique and suture material do not have a major impact on outcomes in ventral hernia repair. Despite a significantly higher rate of SSO for absorbable sutures than permanent, this did not increase the rate of interventions.

Reduced wound leakage in arthroplasty with modified wound closure: a retrospective cohort study.

INTRODUCTION: Wound leakage has been shown to increase the risk of prosthetic joint infections (PJIs) in primary total hip (THA) and knee arthroplasty (unicondylar and total knee arthroplasty; KA). The aim of this study is to determine whether the addition of a continuous subcuticular bonding stitch to a conventional three-layer closure method reduces the incidence of prolonged wound leakage and PJIs after THA and KA. MATERIALS AND METHODS: This retrospective cohort study included all patients receiving a THA or KA. Patients in the control group with a three-layer closure method had surgery between November 1st 2015 and October 31st 2016, and were compared to the study group with a four-layer closure method that had surgery between January 1st 2017 and December 31st 2018. The primary outcome was incidence of prolonged wound leakage longer than 72 h. Differences were evaluated using logistic regression. Incidence of PJIs was the secondary outcome. RESULTS: A total of 439 THA and 339 KA in the control group and 460 THA and 350 KA in the study group were included. In the control group, 11.7% of the patients had a prolonged leaking wound compared to 1.9% in the study group (p < 0.001). The modified wound closure method showed a protective effect for obtaining prolonged wound leakage; odds ratios were 0.09 (95% CI 0.04-0.22; p < 0.001) for THA and 0.21 (95% CI 0.10-0.43; p < 0.001) for KA. PJIs decreased from 1.54 to 0.37% (p = 0.019). CONCLUSIONS: The addition of a continuous subcuticular bonding stitch reduces the incidence of prolonged wound leakage and PJIs after THA and KA compared to a conventional three-layer wound closure method. The large reduction of incidence in wound leakage and PJIs in this study, combined with relatively negligible cost and effort of the modified wound closure method, would advocate for implementing this wound closure method in arthroplasty.
