Strategies to Minimize Sternal and Leg Wound Complications after Coronary Artery Bypass Grafting Using No-Touch Saphenous Vein Grafts.

PURPOSE: The aims of the present study were to examine sternal and saphenous vein (SV) harvest site wound complication rates, and to assess the strategies to minimize the sternal and leg wound complications after coronary artery bypass grafting using a no-touch (NT) SV. METHODS: Patients who underwent coronary artery bypass grafting (CABG) using internal thoracic artery (ITA) and/or NT SV grafts from March 2021 to June 2023 (N = 166) at a newly opened cardiac surgical program were included. We obeyed the current guidelines for the prevention of sternal wound infection. In addition, unilateral ITA was used in most of the patients and the sternal wound was meticulously closed using multiple sternal wires (≥7) and ZipFix. For the NT SV harvesting, the LigaSure device was used to minimize thermal injury, and the wound was meticulously closed. RESULTS: Sternal wound infections developed in 3/166 (1.8%) patients; all three patients showed superficial sternal wound infections. Leg wound complications were present in 2/153 (1.3%) patients, who recovered after secondary intention healing. CONCLUSION: Sternal wound complications after CABG could be minimized by the unilateral ITA usage, meticulous closure of the sternal wound in addition to compliance with the current guidelines. Wound complications after NT SV harvest may also be minimized by preoperative evaluation, careful harvesting, and meticulous wound closure.

Left ventricular assist device-associated driveline infections as a specific form of complicated skin and soft tissue infection/acute bacterial skin and skin structure infection - issues and therapeutic options.

PURPOSE OF REVIEW: This review comments on the current guidelines for the treatment of wound infections under definition of acute bacterial skin and skin structure infections (ABSSSI). However, wound infections around a catheter, such as driveline infections of a left ventricular assist device (LVAD) are not specifically listed under this definition in any of the existing guidelines. RECENT FINDINGS: Definitions and classification of LVAD infections may vary across countries, and the existing guidelines and recommendations may not be equally interpreted among physicians, making it unclear if these infections can be considered as ABSSSI. Consequently, the use of certain antibiotics that are approved for ABSSSI may be considered as 'off-label' for LVAD infections, leading to rejection of reimbursement applications in some countries, affecting treatment strategies, and hence, patients' outcomes. However, we believe driveline exit site infections related to LVAD can be included within the ABSSSI definition. SUMMARY: We argue that driveline infections meet the criteria for ABSSSI which would enlarge the 'on-label' antibiotic armamentarium for treating these severe infections, thereby improving the patients' quality of life.

Long-term outcomes and complications of isolated anterior thoracolumbar fusion for neuromuscular scoliosis associated with myelomeningocele.

PURPOSE: Neuromuscular scoliosis associated with myelomeningocele is a difficult clinical dilemma for the treating surgeon. The traditional surgical treatment consists of a posterior spinal instrumented fusion with or without a combined anterior procedure, but this has been associated with high complication rates, mostly related to deep infection. An anterior thoracolumbar fusion is not able to address the entirety of the deformity in many cases but could potentially avoid the devastating infection risks from the posterior approach by avoiding compromised skin. This study aims to evaluate the long-term outcomes and complications associated with isolated anterior thoracolumbar fusion in this high-risk group. METHODS: This study is a retrospective analysis of patients with myelomeningocele-associated scoliosis treated with an isolated anterior spinal fusion over a 20-year time period at a single center. Surgical details, demographics, curve characteristics and complications were recorded. Comparisons were made between patients who required revision surgery and those who did not. RESULTS: Sixteen patients were enrolled with an average age of 12.7 years at the time of surgery and average follow-up of 5.5 years. Patients had on average 7.4 levels fused anteriorly with the most common levels being T10-L4. There were no deep wound infections associated with the anterior surgery. Overall, nine patients (56%) had to be revised posteriorly due to adding-on or junctional deformity at an average of 3.7 years after index procedure. Four patients were revised due to proximal adding-on, while 1 was extended distally. Four additional patients were extended both proximally and distally. Of the posterior revisions, 2 patients developed deep wound infections, and both of these were in patients extended distally. Preoperative lumbar lordosis was higher in patients who required distal extension (100 vs. 69 degrees; p = 0.035). CONCLUSIONS: Patients undergoing isolated anterior fusion for scoliosis associated with myelomeningocele have low infection rates but often require posterior revision. The majority of patients can avoid the deep infection risk associated with distal posterior surgery at long-term follow-up. LEVEL OF EVIDENCE: IV.

Major complications after total hip arthroplasty with the direct anterior approach at a high-volume Ontario tertiary care centre.

BACKGROUND: The rate of major surgical complications for high-volume orthopedic surgeons using the direct anterior approach (DAA) in Ontario, Canada, is not known. The purpose of this study was to investigate the rate of major surgical complications after total hip arthroplasty (THA) using DAA performed by experienced orthopedic surgeons at a high-volume tertiary care centre in Ontario. METHODS: We conducted a retrospective cohort review of primary THA through DAA performed by 2 experienced fellowship-trained surgeons at an academic hospital in London, Ontario, between Jan. 1, 2012, and May 1, 2019. We excluded the first 100 cases to allow for surgeon learning curves. We recorded major surgical complications (intraoperative events, postoperative periprosthetic fractures, dislocation requiring closed or open reduction, implant failure [aseptic loosening or subsidence], early (< 6 wk) deep wound infection requiring irrigation and débridement, late (≥ 6 wk) deep wound infection requiring irrigation and débridement, and wound complications [wound dehiscence, stitch abscess, erythema, hematoma or seroma]) within 1 year of THA. RESULTS: A total of 875 primary DAA THA procedures were included. The rates of surgical complications were 0.9% for intraoperative events, 1.5% for postoperative periprosthetic fractures, 0.8% for implant failure, 0.7% for early deep wound infection, 0.1% for late deep wound infection and 3.2% for wound complications; there were no cases of dislocation. The rate of revision for implant failure within 1 year was 0.1%. Male sex was associated with a greater risk of implant failure (p = 0.01), and having a higher body mass index was associated with both increased rates of infection (p < 0.01) and having a wound complication (p < 0.01). CONCLUSION: Intraoperative events, postoperative periprosthetic fractures, implant failure, deep wound infection and wound complications accounted for the major surgical complications within 1 year of THA through DAA. The low revision rate suggests that DAA is a safe approach for THA.

Blood transfusions in non-major burns patients.

BACKGROUND: Blood transfusions are essential to treating anaemia of burn injuries. It has recently been observed that patients with non-major burns < 20%TBSA may also develop anaemia requiring transfusion of blood products. Due to the morbidity and mortality rate associated with blood transfusions better understanding of risk factors may guide clinical practices to improve patient care. OBJECTIVE: To determine risk factors for transfusion of blood products in patients with non-major burn injuries and assess transfusion practices to establish impact on patient outcome. METHOD: Our study included 182 adult patients with non-major burn injuries, < 20%TBSA admitted over a 3-year period at the Department of Plastic Surgery and Burns Unit of the Emergency County Hospital Cluj-Napoca. We analysed patient and injury characteristics: age, gender, %TBSA burn, %FT burn, burn site, mechanism of injury, inhalation injury, Hb lab determinations throughout admission and surgical management. Charlson comorbidities index has been determined based on cardiovascular, neurological, gastrointestinal and renal comorbidities as well as diabetes mellitus. We selected blood transfusions, wound infections and length of hospital stay as outcome for our analysis. RESULTS: 37.9% of patients included in our study developed anaemia throughout admission and 7.7% underwent blood transfusions. Mean Hb levels triggering blood transfusions have been recorded at 7.4 (IQR=8.8-9.9) g/dL. Patients who received transfusions were older, presented with higher %TBSA and associated a higher comorbidity index. They also tended to develop coagulopathy and underwent more surgical procedures to achieve wound closure. In transfused patients who associate comorbidities we observed a higher rate of wound infections and longer hospital stay. CONCLUSIONS: Patient related comorbidities correlate with higher transfusion rates in non-major burn injuries. Due to the risk associated with the use of blood products decision to transfuse should adhere to current guideline practices and be tailored to specific patient requirements.

Selective Deep Lobe Parotidectomy vs Total Parotidectomy for Patients With Benign Deep Lobe Parotid Tumors.

Importance: Limited literature exists on surgical outcomes after selective deep lobe parotidectomy (SDLP) with preservation of superficial lobe for patients with benign deep lobe tumors. Objective: To compare the following factors for SDLP vs total parotidectomy for patients with benign tumors in the deep lobe: postoperative complications, including facial nerve paresis or paralysis, Frey syndrome, first bite syndrome, cosmetic defect, sialocele formation, and wound infection; and tumor control and recurrence. Design, Setting, and Participants: This case series included 273 adults who underwent SDLP (n = 177) or total parotidectomy (n = 96) at a single tertiary care institution for benign parotid tumors located in the deep lobe or deep lobe and parapharynx from January 1, 2000, to December 31, 2020. Exposure: Selective deep lobe parotidectomy vs total parotidectomy. Main Outcomes and Measures: Incidence of postoperative complications and tumor recurrence. Results: Among 273 patients (SDLP, 177 [65%]; 122 women [69%]; median age at surgery, 58 years [IQR, 46-67 years]; total parotidectomy, 96 [35%]; 57 women [59%]; median age at surgery, 59 years [IQR, 40-68 years]), the most common tumor was pleomorphic adenoma (SDLP, 128 of 177 [72%]; total parotidectomy, 62 of 96 [65%]). An abdominal dermal fat graft was less commonly performed for patients who underwent SDLP than those who underwent total parotidectomy (2 of 177 [1%] vs 20 of 96 [21%]; difference, -20% [95% CI, -28% to -11%]). The rate of great auricular nerve preservation was higher in the SDLP group than in the total parotidectomy group (84 of 102 [82%] vs 20 of 34 [59%]; difference, 24% [95% CI, 5%-42%]). No meaningful difference in length of hospital stay was found. The percentage of patients with House-Brackmann grade I immediately after surgery was 48% (85 of 177) in the SDLP group and 21% (20 of 96) in the total parotidectomy group (difference, 28% [95% CI, 16%-40%]). There were no clinically meaningful differences in rates of hematoma, sialocele, seroma, ear numbness, wound infection, or unplanned return to emergency department or operating room. The SDLP group reported a lower rate of Frey syndrome than the total parotidectomy group (1 of 137 [1%] vs 12 of 78 [15%]; difference, -15% [95% CI, -23% to -7%]), as well as a lower rate of facial contour defect (28 of 162 [17%] vs 25 of 84 [30%]; difference, -13% [95% CI, -24% to -1%]) and a higher rate of first bite syndrome (34 of 148 [23%] vs 7 of 78 [9%]; difference, 14% [95% CI, 5%-23%]). The percentage of patients with House-Brackmann grade I at their first follow-up visit was 67% (118 of 177) in the SDLP group compared with 49% (47 of 96) in the total parotidectomy group (difference, 17% [95% CI, 4%-30%]). There was no clinically meaningful difference in House-Brackmann grade after 1 year. Conclusions and Relevance: Findings of this case series study suggest that SDLP can be considered an effective and even superior technique for management of benign tumors in the deep parotid lobe. Advantages associated with SDLP include reduction in need for reconstruction for facial contour defect and reduction in complications, such as immediate facial nerve weakness and Frey syndrome. The incidence of first bite syndrome was higher in the SDLP group. Tumor control was not compromised by SLDP.

Maternal obesity and the risk of postpartum infections according to mode of delivery.

OBJECTIVE: The aim of the present study was to assess the impact of different maternal Body Mass Index (BMI) classes on the risk of postpartum endometritis, wound infection, and breast abscess after different modes of delivery. Secondly to estimate how the risk of postpartum infection varies with different maternal BMI groups after induction of labor and after obstetric anal sphincter injuries. METHODS: A population-based observational study including women who gave birth during eight years (N = 841,780). Data were collected from three Swedish Medical Health Registers, the Swedish Medical Birth Register, the Swedish National Patient Register, and the Swedish Prescribed Drug Register. Outcomes were defined by ICD-10 codes given within eight weeks postpartum. The reference population was uninfected women. Odds ratios were determined using Mantel-Haenszel technique. Year of delivery, maternal age, parity and smoking in early pregnancy were considered as confounders. RESULTS: There was a dose-dependent relationship between an increasing maternal BMI and a higher risk for postpartum infections. Women in obesity class II and III had an increased risk for endometritis after normal vaginal delivery aOR 1.45 (95% CI: 1.29-1.63) and for wound infections after cesarean section aOR 3.83 (95% CI: 3.39-4.32). There was no difference in how maternal BMI affected the association between cesarean section and wound infection, regardless of whether it was planned or emergent. Women in obesity class II and III had a lower risk of breast abscess compared with normal-weight women, aOR 0.47 (95% CI: 0.38-0.58). The risk of endometritis after labor induction decreased with increasing maternal BMI. The risk of wound infection among women with an obstetrical sphincter injury decreased with increasing BMI. CONCLUSION: This study provides new knowledge about the impact of maternal BMI on the risk of postpartum infections after different modes of delivery. There was no difference in how BMI affected the association between cesarean section and wound infections, regardless of whether it was a planned cesarean section or an emergency cesarean section.

The impact of sarcobesity on incisional hernia after laparoscopic colorectal cancer surgery.

PURPOSE: Incisional hernia is a common complication after abdominal surgery, especially in obese patients. The aim of the present study was to evaluate the relationship between sarcobesity and incisional hernia development after laparoscopic colorectal cancer surgery. METHODS: In total, 262 patients who underwent laparoscopic colorectal cancer surgery were included in the present study. Univariate and multivariate analyses were performed to evaluate the independent risk factors for the development of incisional hernia. We then performed subgroup analyses to assess the impact of visceral obesity according to clinical variables on the development of incisional hernia in laparoscopic surgery for colorectal cancer surgery. RESULTS: Forty-four patients (16.8%) developed incisional hernias after laparoscopic colorectal cancer surgery. In the univariate analysis, the development of incisional hernia was significantly associated with female sex (P = 0.046), subcutaneous obesity (P = 0.002), visceral obesity (P = 0.002), sarcobesity (P < 0.001), and wound infection (P < 0.001). In the multivariate analysis, sarcobesity (P < 0.001) and wound infection (P < 0.001) were independent predictors of incisional hernia. In subgroup analysis, the odds ratio of visceral obesity was the highest (13.1; 95% confidence interval [CI], 4.51-37.8, P < 0.001) in the subgroup of sarcopenia. CONCLUSION: Sarcobesity may be a strong predictor of the development of incisional hernia after laparoscopic surgery for colorectal cancer, suggesting the importance of body composition in the development of incisional hernia.

Minithoracotomy versus sternotomy in mitral valve surgery: meta-analysis from recent matched and randomized studies.

BACKGROUND: There is still ongoing debate about the benefits of mini-thoracotomy (MTH) approach in mitral valve surgery in comparison with complete sternotomy (STER). This study aims to update the current evidence with mortality as primary end point. METHODS: The MEDLINE and EMBASE databases were searched through June 2022. Two randomized studies and 16 propensity score matched studies published from 2011 to 2022 were included with a total of 12,997 patients operated on from 2005 (MTH: 6467, STER: 6530). Data regarding early mortality, stroke, reoperation for bleeding, new renal failure, new onset of atrial fibrillation, need of blood transfusion, prolonged ventilation, wound infection, time-related outcomes (cross clamp time, cardiopulmonary bypass time, ventilation time, length of intensive care unit stay, length of hospital stay), midterm mortality and reoperation, and costs were extracted and submitted to a meta-analysis using weighted random effects modeling. RESULTS: The incidence of early mortality, stroke, reoperation for bleeding and prolonged ventilation were similar, all in the absence of heterogeneity. However, the sub-group analysis showed a significant OR in favor of MTH when robotic enhancement was used. New renal failure (OR 1.67, 95% CI 1.06-2.62, p = 0.03), new onset of atrial fibrillation (OR 1.31, 95% CI 1.15-1.51, p = 0.001) and the need of blood transfusion (OR 1.77, 95% CI 1.39-2.27, p = 0.001) were significantly lower in MTH group. Regarding time-related outcomes, there was evidence for important heterogeneity of treatment effect among the studies. Operative times were longer in MTH: differences in means were 20.7 min for cross clamp time (95% CI 14.9-26.4, p = 0.001), 36.8 min for CPB time (95% CI 29.8-43.9, p = 0.001) and 37.7 min for total operative time (95% CI 19.6-55.8, p < 0.001). There was no significant difference in ventilation duration; however, the differences in means showed significantly shorter ICU stay and hospital stay after MTH compared to STER: - 0.6 days (95% CI - 1.1/- 0.21, p = 0.001) and - 1.88 days (95% CI - 2.72/- 1.05, p = 0.001) respectively, leading to a significant lower hospital cost after MTH compared to STER with difference in means - 4528 US$ (95% CI - 8725/- 326, p = 0.03). The mid-term mortality was significantly higher after STER compared to MTH: OR = 1.50, 1.09-2.308 (95% CI), p = 0.01; the rate of mid-term reoperation was reported similar in MTH and STER: OR = 0.76, 0.50-1.15 (95% CI), p = 0.19. CONCLUSIONS: The present meta-analysis confirms that the MTH approach for mitral valve disease remains associated with prolonged operative times, but it is beneficial in terms of reduced postoperative complications (renal failure, atrial fibrillation, blood transfusion, wound infection), length of stay in ICU and in hospitalization, with finally a reduction in global cost. MTH approach appears associated with a significant reduction of postoperative mortality that must be confirmed by large randomized study.

Trend of unplanned reoperation rates after lumbar degenerative surgery from 2011 to 2019: a large patient population study.

BACKGROUND: Unplanned reoperation is commonly performed due to postoperative complications. Previous studies have reported the incidence of unplanned reoperation following lumbar spinal surgery. But few study focused on the trend of reoperation rates, and the reasons of unplanned reoperation were not clear. In this study, we conducted a retrospective study to determine the trend of unplanned reoperation rates after degenerative lumbar spinal surgery from 2011 to 2019, and the reasons and risk factors of unplanned reoperation were also determined. METHODS: Data of patients who were diagnosed with degenerative lumbar spinal disease and underwent posterior lumbar spinal fusion surgery in our institution from January 2011 to December 2019 were reviewed. Those who received unplanned reoperation during the primary admission were identified. The demographics, diagnosis, surgical segments and postoperative complications of these patients were recorded. The rates of unplanned reoperation from 2011 to 2019 were calculated, and the reasons of unplanned reoperation were statistically analysed. RESULTS: A total of 5289 patients were reviewed. Of them, 1.91% (n = 101) received unplanned reoperation during the primary admission. The unplanned reoperation rates of degenerative lumbar spinal surgery firstly increased from 2011 to 2014, with a peak rate in 2014 (2.53%). Then, the rates decreased from 2014 to 2019, with the lowest one in 2019 (1.46%). Patients with lumbar spinal stenosis have a higher rate of unplanned reoperation (2.67%) compared with those diagnosed as lumbar disc herniation (1.50%) and lumbar spondylolisthesis (2.04%) (P < 0.05). The main reasons for unplanned reoperation were wound infection (42.57%), followed by wound hematoma (23.76%). Patients who underwent 2-segment spinal surgery had a higher unplanned reoperation rate (3.79%) than those receiving other segments surgery (P < 0.001). And different spine surgeons had different reoperation rates. CONCLUSIONS: The rates of unplanned reoperation after lumbar degenerative surgery increased at first and then decreased during past 9 years. Wound infection was the major reason for unplanned reoperation. 2-segment surgery and surgeon's surgical skills were related to the reoperation rate.

Delirium After Surgery for Proximal Femoral Fractures in the Frail Elderly Patient: Risk Factors and Clinical Outcomes.

Purpose: The primary aim of this study was to identify risk factors for delirium after hip fracture surgery. The secondary purpose of this study was to verify peri-operative clinical outcomes, adverse events and mortality rates in delirium patients after hip fracture surgery. Patients and Methods: A prospective hip fracture database was used to obtain data. In total, 2051 patients older than 70 years undergoing a hip fracture surgery between 01-01-2018 and 01-01-2021 were included. A delirium was diagnosed by a geriatrician based on the DSM-V criteria. Results: The results showed that 16% developed a delirium during hospital admission. Multivariable analysis showed that male gender (OR: 1.99, p<0.001), age (OR: 1.06, p<0.001), dementia (OR: 1.66, p=0.001), Parkinson's disease (OR: 2.32, p=0.001), Δhaemoglobin loss (OR: 1.19, p=0.022), pneumonia (OR: 3.86, p<0.001), urinary tract infection (UTI) (OR: 1.97, p=0.001) and wound infection (OR: 3.02, p=0.007) were significant independent prognostic risk factors for the development of a delirium after hip surgery. The median length in-hospital stay was longer in patients with a delirium (9 days) vs patients without a delirium (6 days) (p<0.001). The 30-day mortality was 7% (with delirium 16% vs with no delirium 6% (p<0.001)). Conclusion: Significant independent prognostic factors associated with delirium after hip surgery were male gender, age, dementia, Parkinson's disease, Δhaemoglobin loss, pneumonia, UTI and wound infection.

Pure laparoscopic versus open left lateral hepatectomy in pediatric living donor liver transplantation: a review and meta-analysis.

PURPOSE: The meta-analysis was conducted to evaluate the safety and feasibility of pure laparoscopic left lateral hepatectomy in comparison with open approach for pediatric living donor liver transplantation (LDLT). METHODS: A systemic literature survey was performed by searching the PubMed, EMBASE and Cochrane Library databases for articles that compared pure laparoscopic left lateral living donor hepatectomy (LLDH) and open left lateral living donor hepatectomy (OLDH) by November 2021. Meta-analysis was performed to assess donors' and recipients' perioperative outcomes using RevMan 5.3 software. RESULTS: A total of five studies involving 432 patients were included in the analysis. The results demonstrated that LLDH group had significantly less blood loss (WMD = -99.28 ml, 95%CI -152.68 to -45.88, p = 0.0003) and shorter length of hospital stay (WMD = -2.71d, 95%CI -3.78 to -1.64, p < 0.00001) compared with OLDH group. A reduced donor overall postoperative complication rate was observed in the LLDH group (OR = 0.29, 95%CI 0.13-0.64, p = 0.002). In the subgroup analysis, donor bile leakage, wound infection and pulmonary complications were similar between two groups (bile leakage: OR = 1.31, 95%CI 0.43-4.02, p = 0.63; wound infection: OR = 0.38, 95%CI 0.10-1.41, p = 0.15; pulmonary complications: OR = 0.24, 95%CI 0.04-1.41, p = 0.11). For recipients, there were no significant difference in perioperative outcomes between the LLDH and OLDH group, including mortality, overall complications, hepatic artery thrombosis, portal vein and biliary complications. CONCLUSION: LLDH is a safe and effective alternative to OLDH for pediatric LDLT, reducing invasiveness and benefiting postoperative recovery. Future large-scale multi-center studies are expected to confirm the advantages of LLDH in pediatric LDLT.

Factors Influencing Hospital Readmission after Lower Extremity Bypass for Chronic Limb-Threatening Ischemia.

Objectives: Unplanned hospital readmission is a leading source of hospital resource expenditure, and preventing readmission may improve both patient quality of life and healthcare costs. The factors influencing hospital readmission after lower extremity bypass (LEB) for chronic limb-threatening ischemia (CLTI) remain incompletely investigated. Methods: A regional, multi-institutional database was retrospectively reviewed for all patients who underwent LEB for CLTI between 1995 to 2020. The primary outcome was unplanned hospital readmission up to 30 days following bypass. Results: A total of 1315 patients underwent LEB across all institutions, of whom 843 (64.1%) underwent bypass for CLTI. The 30-day hospital readmission rate was 25.3%, and the leading causes of readmission were wound-related complications (51.6%). There was no difference in age, sex, or race between readmitted and non-readmitted patients. Conduit type and bypass target were also similar between groups. Readmitted patients more frequently underwent LEB for tissue loss (58.2% vs 50.2%, P = 0.042). On multivariable analysis, wound infection (odds ratio [OR] 9.1, 95% confidence interval [CI] 6.2-13.2, P < 0.001) and non-infectious wound complications (OR 2.0, 95% CI 1.0-3.9, P = 0.041) were independently associated with hospital readmission. Factors not associated with hospital readmission included patient age, conduit type, distal bypass target, and other medical comorbidities. Conclusions: One quarter of patients are readmitted within 30 days following lower extremity bypass for chronic limb-threatening ischemia. Efforts to mitigate wound infection and non-infectious wound complications may decrease rates of unplanned hospital readmission.

Off-Pump Bilateral Skeletonized Internal Thoracic Artery Grafting in Octogenarians.

BACKGROUND: We compared postoperative outcomes in octogenarians who underwent off-pump isolated coronary artery bypass grafting for multivessel disease using either skeletonized bilateral or single internal thoracic artery (ITA).Methods and Results: Among 1,532 patients who underwent isolated coronary artery bypass grafting between 2002 and 2021, 173 octogenarians were analyzed retrospectively. After inverse probability of treatment weighting, we found no statistically significant difference regarding patients' preoperative characteristics. No patient experienced deep sternal wound infection. More patients in the single than bilateral ITA group died within 30 days after surgery (5.0% vs. 0%, respectively; P=0.003). The mean follow-up duration was 4.2 years. At 5 years, the freedom from overall death following bilateral versus single ITA grafting was 78.2% and 53.7%, respectively (log-rank test, P=0.003), and freedom from major adverse cardiac and cerebrovascular events (MACCE) was 67.9% and 44.8% respectively (log-rank test, P=0.002). In multivariable Cox models, bilateral ITA grafting was significantly associated with a lower risk of overall death (hazard ratio [HR] 0.555; 95% confidence interval [CI] 0.342-0.903; P=0.018) and MACCE (HR 0.586; 95% CI 0.376-0.913; P=0.018). CONCLUSIONS: Compared with single ITA grafting, off-pump skeletonized bilateral ITA grafting is associated with lower rates of overall death and MACCE in octogenarians undergoing CABG and does not increase the risk of deep sternal wound infection.

Incidence of complications associated with cervical spine surgery and post-operative physical therapy and implications for timing of initiation of post-operative physical therapy: a retrospective database study.

PURPOSE: To describe the incidence of complications associated with cervical spine surgery and post-operative physical therapy (PT), and to identify if the timing of initiation of post-operative PT impacts the incidence rates. METHODS: MOrtho PearlDiver database was queried using billing codes to identify patients who had undergone Anterior Cervical Discectomy and Fusion (ACDF), Posterior Cervical Fusion (PCF), or Cervical Foraminotomy and post-operative PT from 2010-2019. For each surgical procedure, patients were divided into three 12-week increments for post-operative PT (starting at post-operative weeks 2, 8, 12) and then matched based upon age, gender, and Charlson Comorbidity Index score. Each group was queried to determine complication rates and chi-square analysis with adjusted odds ratios, 95% confidence intervals, and p-values were used. RESULTS: Following matching, 3,609 patients who underwent cervical spine surgery at one or more levels and had post-operative PT (ACDF:1784, PCF:1593, and cervical foraminotomy:232). The most frequent complications were new onset cervicalgia (2-14 weeks, 8-20 weeks, 12-24 weeks): ACDF (15.0%, 14.0%, 13.0%), PCF (18.8%, 18.0%, 19.9%), cervical foraminotomy (16.8%, 16.4%, 19.4%); revision: ADCF (7.9%, 8.2%, 7.4%), PCF (9.3%, 10.6%, 10.2%), cervical foraminotomy (11.6%, 10.8% and 13.4%); wound infection: ACDF (3.3%, 3.4%, 3.1%), PCF (8.3%, 8.0%,7.7%), cervical foraminotomy (5.2%, 6.5%, < 4.7%). None of the comparisons were statistically significant. CONCLUSION: The most common post-operative complications included new onset cervicalgia, revision and wound infection. Complications rates were not impacted by the timing of initiation of PT whether at 2, 8, or 12 weeks post-operatively.

Randomized Controlled Trial Investigating Perioperative Immunonutrition for Patients Undergoing Cytoreductive Surgery (CRS) and Hyperthermic Intraperitoneal Chemotherapy (HIPEC).

BACKGROUND: Immunonutrition has been shown to reduce hospital stay and postoperative morbidity in patients undergoing gastrointestinal, and head and neck surgery. However, its use has not been demonstrated in patients undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC). This study aims to determine the effectiveness of perioperative immunonutrition on patients undergoing CRS-HIPEC in reducing length of hospitalization and postoperative complications. PATIENTS AND METHODS: From April 2017 to December 2018, patients undergoing CRS-HIPEC for peritoneal metastases in a single center were enrolled in a randomized controlled trial. Patients with evidence of intestinal obstruction or with diabetes mellitus were excluded. Patients were randomly assigned in a 1:1 fashion to receive perioperative oral immunonutrition or standard nutritional feeds. Length of hospital stay and rates of wound infection and complications were recorded and compared between the two groups in an intention-to-treat manner. RESULTS: A total of 62 patients were recruited and randomized into two groups. Compliance to nutritional feeds in the preoperative period was significantly higher in the standard nutrition group (95.2% versus 75.4%, p = 0.004). There was no difference in postoperative compliance rates. Length of hospital stay and rates of wound infection and postoperative complications were higher in the standard nutrition group when compared with patients on immunonutrition (15.5 versus 11.1 days, p = 0.186; 19% versus 9.7%, p = 0.473; 16% versus 9.7%, p = 0.653; respectively). CONCLUSIONS: Patients undergoing CRS-HIPEC who received perioperative immunonutrition had shorter hospitalization and less wound infections and postoperative complications, although the differences with the standard nutrition group were not statistically significant. Potential benefits of perioperative immunonutrition need to be further evaluated in larger studies.

Postoperative complications and oncologic outcomes after multimodal therapy of localized high risk soft tissue sarcoma.

BACKGROUND: Standard therapy for localized high-risk soft tissue sarcoma includes surgical resection and neoadjuvant or adjuvant radiation therapy (± chemotherapy and locoregional hyperthermia). No difference in oncologic outcomes for patients treated with neoadjuvant and adjuvant radiation therapy was reported, whereas side effect profiles differ. The aim of this analysis was to analyse oncologic outcomes and postoperative complications in patients treated with multimodal treatment. METHODS: Oncologic outcomes and major wound complications (MWC, subclassified as wound healing disorder, infection, abscess, fistula, seroma and hematoma) were evaluated in 74 patients with localized high-risk soft tissue sarcoma of extremities and trunk undergoing multimodal treatment, and also separately for the subgroup of lower extremity tumors. Clinical factors and treatment modalities (especially neoadjuvant vs. adjuvant radiotherapy) were evaluated regarding their prognostic value and impact on postoperative wound complications. RESULTS: Oncologic outcomes were dependent on number of high risk features (tumor size, depth to superficial fascia and grading), but not on therapy sequencing (however with higher risk patients in the neoadjuvant group). Different risk factors influenced different subclasses of wound healing complications. Slightly higher MWC-rates were observed in patients treated with neoadjuvant therapy, compared to adjuvant radiotherapy, although only with a trend to statistical significance (31.8% vs. 13.3%, p = 0.059). However, except for wound infections, no significant difference for other subclasses of postoperative complications was observed between neoadjuvant and adjuvant therapy. Diabetes was confirmed as a major risk factor for immune-related wound complications. CONCLUSION: Rates of major wound complications in this cohort are comparable to published data, higher rates of wound infections were observed after neoadjuvant radiotherapy. Tumor localization, patient age and diabetes seem to be major risk factors. The number of risk factors for high risk soft tissue sarcoma seem to influence DMFS. Neoadjuvant treatment increases the risk only for wound infection treated with oral or intravenous antibiotic therapy and appears to be a safe option at an experienced tertiary center in absence of other risk factors.

Laparoscopic versus open repair of congenital duodenal obstruction: a systematic review and meta-analysis.

PURPOSE: To assess the safety and efficacy of laparoscopic versus open repair of congenital duodenal obstruction (CDO), we conducted a systematic review and meta-analysis (CDO). METHODS: A literature search was conducted to identify studies that compared laparoscopic surgery (LS) and open surgery (OS) for neonates with CDO. Meta-analysis was used to pool and compare variables such as operative time, time to feeding, length of hospital stay, anastomotic leak or stricture, postoperative ileus, wound infection, and overall postoperative complications. RESULTS: Among the 1348 neonatal participants with CDO in the ten studies, 304 received LS and 1044 received OS. When compared to the OS approach, the LS approach resulted in shorter hospital stays, faster time to initial and full feeding, longer operative time, and less wound infection. However, no significant difference in secondary outcomes such as anastomotic leak or stricture, postoperative ileus, and overall postoperative complications was found between LS and OS. CONCLUSIONS: LS is a safe, feasible and effective surgical procedure for neonatal CDO when compared to OS. Compared with OS, LS has a faster time to feeding, a shorter hospital stay, and less wound infection. Furthermore, in terms of anastomotic leak or stricture, postoperative ileus, and overall postoperative complications, LS is equivalent to OS. We conclude that LS should be considered an acceptable option for CDO.
