Evaluation of long-term outcome following therapeutic mammaplasty: the effect of wound complication on initiation of adjuvant therapy and subsequent oncological outcome.

Therapeutic mammaplasty (TM) facilitates large tumour resection while maintaining optimal aesthetic outcome. It carries higher wound complication risks, which may delay adjuvant therapy initiation. Whether this delay affects oncological outcome requires evaluation. Data were collected for consecutive patients receiving TM at the Leeds breast unit (2009-2017). A prospectively maintained database was used to determine tumour characteristics, wound complication rates, receipt of adjuvant therapy and breast cancer recurrence or death. In total 112 patients (median age of 54 years) underwent 114 TM procedures. The most common histological subtypes were invasive ductal carcinoma (61.4%), invasive lobular carcinoma (13.2%) and ductal carcinoma in situ (13.2%). Of the patients, 88.2% had oestrogen receptor-positive cancer and 14% had human epidermal growth factor receptor-positive cancer; 26.3% had multifocal cancer. The median tumour size was 30mm. The median Nottingham Prognostic Index was 4.2. The local recurrence rate was 3.5% (median follow-up of 8.6 years). The 5- and 10-year disease-free survival (DFS) was 88.5% and 83.5%, and the equivalent overall survival (OS) rates were 94% and 83.5%. Wound complication rate was 23.6% (n=27), the commonest being wound infection (11.4%; n=13) and T-junction wound breakdown (10.5%; n=12). The median time to adjuvant therapy was 72 days (interquartile range [IQR] 56-90) for patients with wound complications, and 51 days (IQR 42-58) for those without. However, this delay did not affect DFS or OS (log-rank test; p=0.58 and p=0.94, respectively). This was confirmed on Cox regression analysis. Our study finding demonstrates that although wound complications after TM leads to a modest delay to adjuvant therapy, the long-term oncological outcomes were comparable with those in patients without wound complications.

Prospective phase II trial of preoperative hypofractionated proton therapy for extremity and truncal soft tissue sarcoma: the PRONTO study rationale and design

BackgroundOncologic surgical resection is the standard of care for extremity and truncal soft tissue sarcoma (STS), often accompanied by the addition of pre- or postoperative radiation therapy (RT). Preoperative RT may decrease the risk of joint stiffness and fibrosis at the cost of higher rates of wound complications. Hypofractionated, preoperative RT has been shown to provide acceptable outcomes in prospective trials. Proton beam therapy (PBT) provides the means to decrease dose to surrounding organs at risk, such as the skin, bone, soft tissues, and adjacent joint(s), and has not yet been studied in patients with extremity and truncal sarcoma.MethodsOur study titled “PROspective phase II trial of preoperative hypofractionated protoN therapy for extremity and Truncal soft tissue sarcOma (PRONTO)” is a non-randomized, prospective phase II trial evaluating the safety and efficacy of preoperative, hypofractionated PBT for patients with STS of the extremity and trunk planned for surgical resection. Adult patients with Eastern Cooperative Group Performance Status ≤ 2 with resectable extremity and truncal STS will be included, with the aim to accrue 40 patients. Treatment will consist of 30 Gy radiobiological equivalent of PBT in 5 fractions delivered every other day, followed by surgical resection 2–12 weeks later. The primary outcome is rate of major wound complications as defined according to the National Cancer Institute of Canada Sarcoma2 (NCIC-SR2) Multicenter Trial. Secondary objectives include rate of late grade ≥ 2 toxicity, local recurrence-free survival and distant metastasis-free survival at 1- and 2-years, functional outcomes, quality of life, and pathologic response.DiscussionPRONTO represents the first trial evaluating the use of hypofractionated PBT for STS. We aim to prove the safety and efficacy of this approach and to compare our results to historical outcomes established by previous trials. Given the low number of proton centers and limited availability, the short course of PBT may provide the opportunity to treat patients who would otherwise be limited when treating with daily RT over several weeks. We hope that this trial will lead to increased referral patterns, offer benefits towards patient convenience and clinic workflow efficiency, and provide evidence supporting the use of PBT in this setting.Trial registration: NCT05917301 (registered 23/6/2023).

Association of Timing of Hindfoot Arthrodesis and Early Reoperation Rates for Total Ankle Arthroplasty.

Prior literature has demonstrated that ipsilateral hindfoot arthrodesis may increase the risk for reoperation after total ankle arthroplasty (TAA) and that simultaneous hindfoot arthrodesis with TAA could result in short-term clinical and radiologic improvements. The purpose of this study is to compare the reoperation rates after TAA with prior hindfoot arthrodesis vs simultaneous arthrodesis and TAA. Patients who underwent primary TAA were identified in the PearlDiver database. Patients were sorted into 2 study cohorts: hindfoot arthrodesis prior to TAA and simultaneous arthrodesis and TAA. Propensity matched control cohorts were identified for each study group. Multivariate analysis was conducted to account for any confounding variables and covariates when identifying differences in complications between cohorts. 297 patients underwent TAA with prior hindfoot arthrodesis and 174 underwent TAA and hindfoot arthrodesis concurrently. The incidence of reoperation (13.8% vs 5.2%, P < .001) and infection (12.6% vs 5.9%, P = .011) for the simultaneous cohort was higher when compared to the matched control cohort. In contrast, there was no statistically significant difference when comparing the prior arthrodesis cohort to the matched control cohort in reoperation rates (5.1% vs 4.7%, P = .787) or infection rates (4.4% vs 4.8%, P = .734). Those undergoing simultaneous procedures had increased incidences of reoperation, wound complications, infection, and emergency department visits (P < .0167) when compared to the TAA with prior arthrodesis cohort. Patients undergoing TAA and hindfoot arthrodesis concurrently were found to have higher rates of reoperation and infection when compared to the matched control cohort . In contrast, there was no difference in these rates in patients undergoing TAA with prior hindfoot arthrodesis compared with their matched control cohort. Patients undergoing simultaneous procedures had increased rates of reoperations, wound complications, infection, and emergency department visits compared to the TAA with prior arthrodesis cohort. Level III, retrospective comparative database study.

Same-day Discharge for Cleft Palate Repair: A Single-Surgeon Retrospective Analysis.

To evaluate the safety of same-day discharge for patients undergoing primary cleft palate repair. Single-surgeon retrospective review. Tertiary care institution. 40 consecutive patients that underwent primary cleft palate repair by a single surgeon from September 2018 to June 2023. Same-day discharge versus overnight admission after primary palatoplasty. 30-day readmission, reoperation, wound and all-cause complication rate and 1-year fistula incidence. Of 40 total cases, 20 patients were discharged on the same calendar day and 20 patients were admitted for overnight stay following primary cleft palate repair. In the same-day discharge group, readmission incidence was 10%(n = 2), wound complication incidence was 5%(n = 1), and postoperative complication incidence was 15%(n = 3). In comparison, patients admitted overnight had a readmission incidence of 5%(n = 1, P = 1.00), wound complication incidence of 10%(n = 2, P = 1.00), and postoperative complications of 20%(n = 4, P = 1.00) No patients had 30-day reoperations or fistulas at 1 year. A higher proportion of admitted patients held a preoperative diagnosis of unilateral cleft palate and alveolus (Veau 3) as compared to patients discharged on the same day (P = .019). During the postoperative hospital course, admitted patients received significantly more oxycodone at median of 2 doses (IQR 1.00-3.75) and acetaminophen at a median of 4 doses (IQR 3.00-5.00) than patients with same-day discharge with a median of 1 dose (IQR 0.00 -1.00, P < .001). In a low-risk patient population, same-day discharge following primary cleft palate repair may be safely undertaken and result in similar short-term outcomes and 1-year fistula incidence as patients admitted for overnight stay.

INTERNATIONAL DELPHI CONSENSUS ON WOUND CLOSURE AND DRESSING MANAGEMENT IN TOTAL HIP ARTHROPLASTY

The purpose of this modified Delphi study was to obtain consensus on wound closure (including best practices for each tissue layer of closure) and dressing management in total hip arthroplasty (THA), using an evidence-based approach.The Delphi panel included 20 orthopedic surgeons from Europe and North America. Eighteen statements were identified (14 specific to THA and 4 relating to both THA and total knee arthroplasty) using a targeted literature review. Consensus was developed on the statements with up to three rounds of anonymous voting per topic. Panelists ranked their agreement with each statement on a five-point Likert scale. An a priori threshold of 75% was required for consensus.In Round 1, 15 of 18 statements achieved consensus via a structured electronic questionnaire. In Round 2, the 3 statements that did not achieve consensus were revised during a virtual face to face meeting. An additional 2 statements were edited for clarity. In Round 3, the 5 revised statements achieved consensus via a structured electronic questionnaire. Wound closure related interventions that were recommended for use in THA included: 1) barbed sutures over non-barbed sutures (shorter closing times and overall cost savings); 2) subcuticular sutures over skin staples (lower risk of infections and higher patient preference); 3) mesh-adhesives over silver-impregnated dressings (lower rate of wound complications); 4) negative pressure wound therapy over other dressings (lower wound complications and reoperations and fewer dressing changes); 5) triclosan coated sutures (lower risk of surgical site infection).Using a modified Delphi approach, a panel of 20 orthopedic surgeons achieved consensus on 18 statements pertaining to multi-layer wound closure and dressing management in THA. This study forms the basis for identifying critical evidence gaps within wound management to help reduce variability in outcomes during THA.

Primary Arthrodesis with Retrograde Hindfoot Nail for Elderly Patients with Tibia Pilon Fractures and Psychiatric Illness.

Management of tibial pilon fracture in elderly patients with psychiatric illness remains challenging for orthopedic doctors because of patients' poor bone quality and inability for self-care. This study aimed to ascertain the viability and reliability of primary arthrodesis by using retrograde hindfoot nail for these difficult cases. We retrospectively reviewed eight elderly consecutive patients (age older than 65 years) with tibial pilon fractures and psychiatric illness from January of 2012 to December of 2019 in our institute. Primary tibiotalocalcaneal arthrodesis with retrograde hindfoot nail was used as a definitive procedure. The bone union time, wound complication rate, ankle alignment, necessity for narcotic agents, and ambulation status were evaluated. The average length of follow-up was 22.25 months (range, 15-36 months). Additional bone grafting surgery was performed for one patient because of fusion-site nonunion 6 months postoperatively. Another patient required debridement and removal of posterior calcaneal screw because of implant prominence and local infection. Osseous union with angular deformity less than 10° was achieved in all patients finally. The average bone union time was 6.6 months (range, 4-12 months). In terms of walking ability, six patients were capable of outdoor ambulation (classes 2 and 3). Two patients required oral pain medication at the final visit. The current study involved only a small number of patients, and two of the eight cases encountered undesired complications (one local infection and one bone nonunion); however, we believe that our method may serve as a valuable alternative for the treatment of tibial pilon fractures in elderly patients with psychiatric illness, considering the specificity of this fragile population.

Soft Tissue Reconstruction After Sacral Neoplasm Resection: The University of California San Francisco Experience.

Resection of sacral neoplasms such as chordoma and chondrosarcoma with subsequent reconstruction of large soft tissue defects is a complex multidisciplinary process. Radiotherapy and prior abdominal surgery play a role in reconstructive planning; however, there is no consensus on how to maximize outcomes. In this study, we present our institution's experience with the reconstructive surgical management of this unique patient population. We conducted a retrospective review of patients who underwent reconstruction after resection of primary or recurrent pelvic chordoma or chondrosarcoma between 2002 and 2019. Surgical details, hospital stay, and postoperative outcomes were assessed. Patients were divided into 3 groups for comparison based on reconstruction technique: gluteal-based flaps, vertical rectus abdominus myocutaneous (VRAM) flaps, and locoregional fasciocutaneous flaps. Twenty-eight patients (17 males, 11 females), with mean age of 62 years (range, 34-86 years), were reviewed. Twenty-two patients (78.6%) received gluteal-based flaps, 3 patients (10.7%) received VRAM flaps, and 3 patients (10.7%) were reconstructed with locoregional fasciocutaneous flaps. Patients in the VRAM group were significantly more likely to have undergone total sacrectomy (P < 0.01) in a 2-stage operation (P < 0.01) compared with patients in the other 2 groups. Patients in the VRAM group also had a significantly greater average number of reoperations (2 ± 3.5, P = 0.04) and length of stay (29.7 ± 20.4 days, P = 0.01) compared with the 2 other groups. The overall minor and major wound complication rates were 17.9% and 42.9%, respectively, with 17.9% of patients experiencing at least 1 infection or seroma. There was no association between prior abdominal surgery, surgical stages, or radiation therapy and an increased risk of wound complications. Vertical rectus abdominus myocutaneous flaps are a more suitable option for patients with larger defects after total sacrectomy via 2-staged anteroposterior resections, whereas gluteal myocutaneous flaps are effective options for posterior-only resections. For patients with small- to moderate-sized defects, local fasciocutaneous flaps are a less invasive and effective option. Paraspinous flaps may be used in combination with other techniques to provide additional bulk and coverage for especially long postresection wounds. Furthermore, mesh is a useful adjunct for any reconstruction aimed at protecting against intra-abdominal complications.

Parastomal hernia repair, trying to optimize the impossible reconstruction

PurposeParastomal hernias are a common and challenging problem with high rates of wound complications and hernia recurrence after repair. We present our approach to optimizing parastomal hernia repair through preoperative preparation, surgical approach, and postoperative management.MethodsPatients are carefully evaluated and optimized prior to surgery. Our typical surgical approach involves a generous midline laparotomy and retrorectus dissection followed by a posterior component separation with transversus abdominis release. We typically utilize a Sugarbaker technique for retromuscular mesh placement but also use the retromuscular keyhole or cruciate technique if there is insufficient bowel length.ResultsPreviously published results from our institution include wound complication rates of up to 16% after open retromuscular parastomal hernia repair. Stoma-specific complications, such as mesh erosion in the bowel, may be attributed to the mesh placement techniques. Hernia recurrence rates range from 11 to 30% up to 2 years postoperatively.ConclusionWe prefer an open retromuscular approach with a Sugarbaker mesh configuration to treat complex parastomal hernias. However, wound morbidity and repair failure rates remain high, and additional research is needed to optimize surgical outcomes.

Incisional Negative Pressure Wound Therapy After Revascularisation Surgery in Patients with Peripheral Arterial Disease: A Randomised Trial (PICO-Vasc Study)

This study assessed the potential benefits of using incisional negative pressure wound therapy (iNPWT) for patients undergoing revascularisation due to peripheral arterial disease. A prospective randomised controlled trial was conducted to compare the inguinal application of iNPWT vs. standard surgical dressings. Patients were enrolled from February 2021 to November 2022. A total of 133 groin incisions were randomised (66 intervention group, 67 control group). The randomisation sequence was carried out by permuted blocks and allocation assigned by opening opaque envelopes once the revascularisation procedure had finished. Wound healing and complication rates were assessed at post-operative days 5, 14, and 30. Primary and secondary endpoints were: 30 day post-operative surgical site infection (SSI) and surgical site occurrence (SSO) rates, defined as a surgical wound complication other than aSSI. Post-operative SSI was defined according to the US Centers for Disease Control and Prevention criteria. SSO included: wound dehiscence, seroma or lymphocele, haematoma, and lymphorrhagia. The study was registered at ClinicalTrials.gov database (NCT04840576) and reported according to the CONSORT guidelines. iNPWT did not modify the 30 day inguinal SSI and SSO rates (16.7% vs. 20.9% and 37.9% vs. 44.8%; p= .53, relative risk [RR] 0.999, 95% confidence interval [CI] 0.52- 1.88 and p=.42, RR 1.29, 95% CI 0.89- 1.86, respectively). It reduced the early SSO rate (19.7% vs. 35.8%; p=.044, RR 1.45, 95% CI 1.047 - 2.013) and post-operative seroma rate (4.6% vs. 19.4%; p= .014, RR 1.73, 95% CI 1.296- 2.397). There were no differences in SSI and SSO rates, although statistically significant reductions in early SSO rates and seroma were found in the intervention group.

Significance of radiation therapy in the myxoid round-cell liposarcoma treatment regimen.

Because myxoid liposarcomas are more radiosensitive than other soft tissue sarcomas, there have been several reports of 50Gy preoperative radiation therapy combined with surgery, but the wound complication rate is reportedly high. We have performed preoperative irradiation at a reduced dose of 40Gy and definitive radiation therapy for unresectable cases. This study aimed to report the tumor reduction rate and oncological results with a reduced dose of preoperative irradiation and the outcome of definitive irradiation for unresectable cases. Forty-one patients with myxoid liposarcoma treated in our institution between 2002 and 2021 were included. We examined the tumor volume shrinkage rate with preoperative radiation, compared complications and oncological outcomes between preoperative radiation and surgery-only cases, and investigated the prognosis and tumor shrinkage of definitive radiation cases. The total dose irradiated was 40Gy except in two cases. The mean tumor volume reduction rate was 52.0%. A decreased dose of preoperative radiation did not worsen clinical outcomes with fewer complications. The total dose of definitive radiation was approximately 60Gy. The mean tumor volume reduction rate was 55.0%. The tumor shrinkage maintenance rate was 100% in a median follow-up period of 50.5months. Preoperative radiation therapy for myxoid liposarcoma near vital organs is a good approach because even with a reduced dose of 40Gy, significant tumor reduction and excellent results were achieved. Definitive radiation therapy is the recommended treatment for older patients with serious comorbidities or inoperable patients.

Colorectal Anastomosis Versus Colostomy Creation in High MELD Patients: An ACS-NSQIP Analysis.

Liver failure patients are at increased risk of surgical complications. The decision to perform a colonic anastomosis vs a colostomy in urgent colorectal surgery remains unclear. The ACS-NSQIP database was queried for patients undergoing nonelective colorectal surgery between 2016 and 2018. MELD score was calculated and stratified into 3 groups. Subgroup analysis of the high-MELD group was performed. Higher MELD scores were associated with significantly higher mortality. Colostomy formation was consistent between intermediate and high-MELD groups. In high-MELD patients, colonic anastomosis was associated with higher mortality than those receiving colostomy (41.1% vs 28.4%, P < .001). Patients receiving colostomy had higher rates of wound complications, but lower rates of return to OR and non-wound complications. Regression analysis revealed that colostomy formation remained an independent predictor of survival (mortality OR = .594, P < .001). High-MELD patients undergoing nonelective colorectal surgery have increased risk of complications such as mortality. Patients in this group receiving an anastomosis have increased complications and mortality, and may benefit from colostomy formation.

The Impact of Metabolic Syndrome on Post-Operative Outcomes in Abdominal Body Contouring: A Propensity Score-Matched Nationwide Analysis

Abstract Goals/Purpose Metabolic syndrome (MetS) represents cardiometabolic dysregulation, defined by hypertension, obesity, diabetes, and dyslipidemia. Its prevalence is on the rise, affecting approximately 47.3% of U.S. adults. In recent years, MetS has been associated with an elevated risk of postoperative complications. However, there remains a significant gap in our understanding of how patients with MetS fare after abdominal body contouring procedures. The objective of this study is to assess the influence of MetS on postoperative outcomes of abdominal body contouring by concurrent abdominoplasty and panniculectomy. Methods/Technique The ACS-NSQIP database was utilized to identify patients who underwent concurrent abdominoplasty and panniculectomy procedures from 2015 to 2021. Through propensity score matching, distinct cohorts were established based on the presence of MetS, characterized by patients receiving medical interventions for diabetes mellitus and hypertension, with a body mass index exceeding 30kg/m2. Disparities among groups were assessed via unpaired T-tests and Fisher's Exact tests. Logistic regression models were constructed to evaluate the occurrence of mild and severe systemic complications, reoperation rates, and wound complications between these groups. Results/Complications A total of 13,346 patients underwent abdominal body contouring. Following propensity score matching, 586 patients were included in the analysis, with 293 in each group (MetS vs. non-MetS). Bivariate analysis revealed a longer hospital length of stay (2.4 vs. 1.7 days; p=0.002) and higher readmission rates (11.9 vs. 6.5; p=0.031) in the MetS group in comparison to the non-MetS cohort. While surgical-related reasons for readmission were predominant across both groups, statistically significant differences were observed only for medical-related reasons (p=0.028). Logistic regression models demonstrated a statistically significant elevated likelihood of 30-day readmission in the MetS group (OR 1.96; 95% CI 1.091-3.507; p=0.024). No noteworthy disparities were observed in the rates of 30-day wound complications, mild systemic, and severe systemic complications between the groups. Conclusion Our findings revealed no increase in postoperative wound and systemic complications among patients with MetS who underwent concurrent abdominoplasty and panniculectomy. This suggests that abdominal body contouring remains a secure option for patients with MetS. Nonetheless, the higher readmission rates and longer hospital length stays observed in patients with MetS may potentially translate to increased overall costs. Continued research is warranted to comprehensively assess the economic implications of MetS in the context of abdominal body contouring.

Improvement of Transfusion Practice in Cardiothoracic Surgery Through Implementing a Patient Blood Management Program.

In this study, we examined the impact of a patient blood management (PBM) program on red blood cell (RBC) transfusion practices in cardiothoracic surgery. The PBM program had 3 components: monitoring transfusions through an order communication system checklist, educating the medical team about PBM, and providing feedback to ordering physicians on the appropriateness of transfusion. The retrospective analysis examined changes in the hemoglobin levels triggering transfusion and the proportions of appropriate RBC transfusions before, during, and after PBM implementation. Further analysis was focused on patients undergoing cardiac surgery, with outcomes including 30-day mortality, durations of intensive care unit and hospital stays, and rates of pneumonia, sepsis, and wound complications. The study included 2,802 patients admitted for cardiothoracic surgery. After the implementation of PBM, a significant decrease was observed in the hemoglobin threshold for RBC transfusion. This threshold dropped from 8.7 g/dL before PBM to 8.3 g/dL during the PBM education phase and 8.0 g/dL during the PBM feedback period. Additionally, the proportion of appropriate RBC transfusions increased markedly, from 23.9% before PBM to 34.9% and 58.2% during the education and feedback phases, respectively. Among the 381 patients who underwent cardiac surgery, a significant reduction was noted in the length of hospitalization over time (p<0.001). However, other clinical outcomes displayed no significant differences. PBM implementation effectively reduced the hemoglobin threshold for RBC transfusion and increased the rate of appropriate transfusion in cardiothoracic surgery. Although transfusion practices improved, clinical outcomes were comparable to those observed before PBM implementation.

Perioperative intravenous dexamethasone use is not associated with periprosthetic joint infection or wound healing complications following shoulder arthroplasty

BackgroundPerioperative intravenous (IV) dexamethasone is commonly used in lower extremity total joint arthroplasty to manage postoperative pain and nausea/vomiting, and recent studies have demonstrated that its use may lower rates of acute postoperative medical complications. However, there is limited information regarding the safety and efficacy of IV dexamethasone in patients undergoing total shoulder arthroplasty (TSA). Additionally, there is concern surrounding corticosteroid use prior to surgery as preoperative corticosteroid injections have been associated with adverse outcomes after TSA, including periprosthetic joint infection (PJI) and revision surgery. Thus, the purpose of this study was to evaluate the effect of perioperative IV dexamethasone on 90-day rates of PJI, wound complications, and medical complications after TSA. MethodsThe Premiere national hospital database was used to identify adult patients undergoing elective TSA between 2016 and 2020; patients were excluded if they were under 18 years old, were undergoing revision TSA, or had a prior proximal humerus open reduction internal fixation (ORIF) procedure. Patients who did and did not receive perioperative IV dexamethasone were then compared in both univariate and multivariate analyses. A Bonferroni correction was utilized to adjust for multiple comparisons. The primary endpoint was risk of acute infectious complications within 90 days of surgery, including PJI and wound infection/dehiscence. Secondary endpoints included acute pulmonary, renal, and thromboembolic complications. ResultsA total of 135,333 patients underwent TSA during the study period; 61.2% underwent reverse total shoulder arthroplasty (RTSA), 33.8% underwent anatomic total shoulder arthroplasty (ATSA), and 5.0% underwent hemiarthroplasty (HA). From 2016 to 2020, perioperative IV dexamethasone use increased by 135%. Multivariate analysis revealed that patients who received perioperative IV dexamethasone did not have increased odds of PJI, superficial wound infection, or wound dehiscence (p = 0.15 – 0.47) but did have decreased odds of sepsis (OR 0.67, 95% CI 0.55-0.81) and other medical complications such as urinary tract infection (UTI) and acute kidney injury (AKI). Additionally, there was a trend towards decreased 90-day hospital readmission (OR 0.88, 95% CI 0.81-0.96, p=0.003). ConclusionsPerioperative IV dexamethasone was not associated with increased risk of acute infectious and wound healing complications. Moreover, patients who received perioperative IV dexamethasone had decreased odds of medical complications and trended towards lower rates of 90-day hospital readmission. The results of this study support the safety of perioperative IV dexamethasone use in patients undergoing elective TSA.

Surgical Approach and Body Mass Index Impact Risk of Wound Complications Following Total Hip Arthroplasty

BackgroundPrevious studies have suggested that wound complications may differ by surgical approach after total hip arthroplasty (THA), with particular attention toward the direct anterior approach (DAA). However, there is a paucity of data documenting wound complication rates by surgical approach and the impact of concomitant patient factors, namely body mass index (BMI). This investigation sought to determine the rates of wound complications by surgical approach and identify BMI thresholds that portend differential risk. MethodsThis multicenter study retrospectively evaluated all primary THA patients from 2010 to 2023. Patients were classified by skin incision as having a laterally based approach (posterior or lateral approach) or DAA (longitudinal incision). We identified 17,111 patients who had 11,585 laterally based (68%) and 5,526 (32%) DAA THAs. The mean age was 65 years (range, 18 to 100), 8,945 patients (52%) were women, and the mean BMI was 30 (range, 14 to 79). Logistic regression and cut-point analyses were performed to identify an optimal BMI cutoff, overall and by approach, with respect to the risk of wound complications at 90 days. ResultsThe 90-day risk of wound complications was higher in the DAA group versus the laterally based group, with an absolute risk of 3.6% versus 2.6% and a multivariable adjusted odds ratio of 1.5 (P < .001). Cut-point analyses demonstrated that the risk of wound complications increased steadily for both approaches, but most markedly above a BMI of 33. ConclusionsWound complications were higher after longitudinal incision DAA THA compared to laterally based approaches, with a 1% higher absolute risk and an adjusted odds ratio of 1.5. Furthermore, BMI was an independent risk factor for wound complications regardless of surgical approach, with an optimal cut-point BMI of 33 for both approaches. These data can be used by surgeons to help consider the risks and benefits of approach selection. Level of EvidenceLevel III.

Knotless suture in revision total joint arthroplasty: a prospective randomized controlled trial.

The use of barbed sutures for wound closure in primary total joint arthroplasty (TJA) has been shown to be effective and safe. However, their effectiveness and safety in revision TJA procedures has not been thoroughly studied. This study aims to evaluate the efficacy and safety of using barbed suture closure in revision TJA setting. A total of 80 patients undergoing revision TJA between September 2020 and November 2022 were included in this randomized controlled trial study. Following informed consent, patients were computer-randomized to the treatment arm (barbed suture wound closure) or to the control arm (conventional wound closure). Closure duration, closure rate, number of sutures used and wound related outcomes including complication rates and Patient and Observer Scar Assessment Scale (POSAS) score were compared between groups. The use of barbed sutures decreased closure time by 6min (30.1 vs. 36.1min, P = 0.008) with a higher wound closure rate (6.5 vs. 5.5mm/minute, P = 0.013). Additionally, the number of sutures used for wound closure in the barbed group was significantly lower than in the control group (6.2 vs. 10.1, respectively, P < 0.001). There were no significant differences in the rate of postoperative wound complications (P = 0.556) or patient and observer POSAS scores (P = 0.211, P = 297, respectively) between the two groups at 3-month follow-up. Closure of revision TJA surgical wound utilizing barbed sutures reduced closure time and the number of needles handled by operative staff, with no significant increase in intra- or post-operative complications rate when compared to traditional closure technique.

Idiopathic intracranial hypertension and obstetric and neonatal outcomes: A 1:20 matched study from a population database.

Idiopathic intracranial hypertension (IIH), also known as pseudotumor cerebri, is a common pathology in reproductive-aged women, although data regarding pregnancy outcomes are scarce. In the present study, we aimed to compare pregnancy and perinatal outcomes between women who suffered from IIH to those who did not. A retrospective cohort study using the Healthcare Cost and Utilization Project, Nationwide Inpatient Sample. All pregnant women who delivered or had a maternal death in the US (2004-2014) were included. Women with an ICD-9 diagnosis of IIH before or during pregnancy were matched to controls without IIH according to age, race, insurance type, and income quartile, in a 1:20 ratio. Pregnancy, delivery, and neonatal outcomes were compared between the two groups. Overall, 9 096 788 deliveries were identified. Of these, 1454 women (0.016%) had a diagnosis of IIH (study group) and were compared to 29 080 women without IIH (control group). Women with IIH, compared to those without, were more likely to be obese (body mass index >30 kg/m2) and suffer from pregestational diabetes mellitus and chronic hypertension (P < 0.001, all). After adjusting for confounders, patients in the IIH group, compared to those without, had a higher rate of pregnancy-induced hypertension (aOR 1.82, 95% CI: 1.57-2.1, P < 0.001), pre-eclampsia (aOR 1.98, 95% CI: 1.61-2.45, P < 0.001), preterm delivery (aOR 1.88, 95% CI: 1.59-2.23, P < 0.001), CD (aOR 2.41, 95% CI: 2.12-2.73, P < 0.001), wound complications (aOR 3.2, 95% CI: 1.89-5.42, P < 0.001), and congenital anomalies (aOR 2.18, 95% CI: 1.4-3.4, P < 0.001). Women with IIH had a higher incidence of obstetrical complications, including preterm deliveries, hypertensive disorders of pregnancy, and congenital anomalies.

Propensity matched analysis of minimally invasive and open radical resection for rectal cancer: comparison of short-term outcomes in elderly/frail patients.

Although minimally invasive surgery (MIS), such as robotic and laparoscopic procedures, is sometimes a better option than open surgery for patients with rectal cancer, it can present challenges for some elderly or frail patients who have a higher risk of chronic illnesses and poor surgical tolerance. On the basis of several pathophysiological characteristics, the patients were grouped according to their age. The time nodes, which are 65 and 80years old, can clarify the goal of the study and offer some therapeutic benefit. These subgroups stand to gain a great deal from MIS because of its superior arm of machinery and imagery. The short-term oncological outcomes and postoperative conditions of robotic surgery, laparoscopic surgery, and conventional open surgery were compared in this study using a propensity-matched analysis. In this retrospective study, a total of 2049 consecutive patients who underwent proctectomy between September 2017 and June 2023 were chosen. We then carried out a propensity matching analysis based on inclusion criteria. Patients were split into two age groups: 65-80 and > 80. While the secondary objective was to further investigate the similar characteristics between RS and LS, the major objective was to compare oncological outcomes and postoperative conditions between MIS and OS. K-M survival curves were used to represent oncological outcomes and survival conditions. Complication rate and mFI score were used to assess postoperative conditions. Regarding the functional outcomes, the LARS scale was applied to create questionnaires that calculated the anal function of the patients. 110 cases from the group of patients aged 65-80 were successfully merged after matching 1: 1 by propensity score, whereas 73 instances from patients aged > 80 were incorporated while examining the primary objective between OS and MIS. Regarding the secondary goal, each group contained 45 cases for patients above 80 and 65 cases for patients aged 65-80, respectively. Faster recovery from MIS included quicker first flatus passage, earlier switch to liquid nutrition, and shorter hospital stay. In the meantime, MIS also showed benefits in terms of the proportion of low mFI scores and the rates of wound complications in the two age groups. Less blood loss and shorter operational time are further MIS features. On the other hand, MIS experienced more pulmonary complications than OS. Robotic surgery was statistically no different from laparoscopic surgery in patients aged 65-80, although it was superior in terms of operative time and recovery. Comparable and satisfactory oncological and survival results were obtained with all three treatments. For elderly/frail patients with rectal cancer, MIS could be recognized as an effective procedure with favorable outcomes of recovery that are accompanied by better postoperative conditions. While, robotic surgery is slightly better than laparoscopic surgery in some aspects. However, to further demonstrate the effectiveness of three surgical modalities in treating certain groups, multi-center prospective studies are required.

High Rate of Undetected Infections in Failed Osteosynthesis of Pertrochanteric Fractures.

The objective of this study was to assess the incidence of infection in patients with cutout after proximal femur fracture (PFF) osteosynthesis. Retrospective cohort study. Third-level trauma center. Patients presenting with a cutout following PFF (OTA/AO 31A) osteosynthesis, between January 2007 and December 2020. The primary outcome was infection according to the European Bone and Joint Infection Society criteria. Sixty-seven patients presenting with a cutout were included, with mean age of 83.3 years (range 63-96), and 51 (76.1%) were women. Of all cases, 16 (24.7%) presented a concomitant infection. The presence of concomitant infection was suspected preoperatively in only 3 of the cases. A subgroup analysis was performed between the cases with infection and those without infection, the groups being comparable in terms of demographic data and postoperative radiological criteria. Patients with underlying infection had a higher rate of surgical wound complication (56.3% vs. 22%, P = 0.014) and higher rates of leukocytosis (11.560 vs. 7.890, P = 0.023). Faced with a cutout after osteosynthesis of a PFF, underlying infection should be considered as a possible etiological factor. Therapeutic Level IV.

Use of Vacuum-Assisted Closure to Reduce the Likelihood of Wound Complications After Limb-Sparing Resection of Pediatric Primary Bone Sarcomas of the Femur

BackgroundLimb-sparing surgery is the standard of care for primary bone tumors. However, such procedures are associated with high rates of wound complications, specifically in lower-extremity surgeries. Therefore, identifying and implementing interventions to minimize the likelihood of wound complications after limb-sparing resection of the lower extremity is crucial. MethodsPatients who underwent limb-sparing osteosarcoma or Ewing sarcoma resection during a 7-year period at a single institution were retrospectively reviewed. Data were collected on 39 patients who underwent limb-sparing resection of the femur. Patient demographics, tumor characteristics, and perioperative and postoperative data were extracted and analyzed. Patients who underwent resection before April 2017 received conventional postoperative incision dressings. Starting in April 2017, patients received vacuum-assisted closure (VAC) with the 3 M™ Prevena VAC system after surgical closure. Eighteen patients received conventional postoperative incision dressing, and 21 received incisional wound VAC. A wound complication was defined as any Clavien-Dindo classification greater than 0 within a 28-day postoperative period. ResultsPatients who received postoperative incisional wound VAC had lower rates of wound complications than those who received conventional incision dressings (14% vs. 50%; p = 0.035). Additionally, patients in whom wound complications developed had a longer average hospital stay than those without wound complications (5 days vs. 4 days; p = 0.029). ConclusionsWound complications prolong the hospital stay and can delay adjuvant chemotherapy for bone tumors. The use of postoperative incisional wound VAC is associated with less likelihood of wound complications and should be considered in any high-risk surgical closure.
