    Mueck, Krislynn M; Kao, Lillian S

    Surgical site infections (SSIs) are a significant healthcare quality issue, resulting in increased morbidity, disability, length of stay, resource utilization, and costs. Identification of high-risk patients may improve pre-operative counseling, inform resource utilization, and allow modifications in peri-operative management to optimize outcomes. Review of the pertinent English-language literature. High-risk surgical patients may be identified on the basis of individual risk factors or combinations of factors. In particular, statistical models and risk calculators may be useful in predicting infectious risks, both in general and for SSIs. These models differ in the number of variables; inclusion of pre-operative, intra-operative, or post-operative variables; ease of calculation; and specificity for particular procedures. Furthermore, the models differ in their accuracy in stratifying risk. Biomarkers may be a promising way to identify patients at high risk of infectious complications. Although multiple strategies exist for identifying surgical patients at high risk for SSIs, no one strategy is superior for all patients. Further efforts are necessary to determine if risk stratification in combination with risk modification can reduce SSIs in these patient populations.

    Venous thromboembolism (VTE) in pediatric surgical patients is a rare event. The risk factors for VTE in pediatric general surgery patients undergoing abdominopelvic procedures are unknown. The American College of Surgeon's National Surgical Quality Improvement Program-Pediatric (NSQIP-P) database (2012-2015) was queried for patients with VTE after abdominopelvic general surgery procedures. Patient and operative variables were assessed to identify risk factors associated with VTE and develop a pediatric risk score. From 2012-2015, 68 of 34,813 (0.20%) patients who underwent abdominopelvic general surgery procedures were diagnosed with VTE. On multivariate analysis, there was no increased risk of VTE based on concomitant malignancy, chemotherapy, inflammatory bowel disease, or laparoscopic surgical approach, while a higher rate of VTE was identified among female patients. The odds of experiencing VTE were increased on stepwise regression for patients older than 15 years and those with preexisting renal failure or a diagnosis of septic shock, patients with American Society of Anesthesia (ASA) classification ≥ 2, and for anesthesia time longer than 2 h. The combination of age > 15 years, ASA classification ≥ 2, anesthesia time > 2 h, renal failure, and septic shock was included in a model for predicting risk of VTE (AUC = 0.907, sensitivity 84.4%, specificity 88.2%). VTE is rare in pediatric patients, but prediction modeling may help identify those patients at heightened risk. Additional studies are needed to validate the factors identified in this study in a risk assessment model as well as to assess the efficacy and cost-effectiveness of prophylaxis methods.

    Surgical cholecystostomy under local infiltration anesthesia was combined with radiologic removal of gallstones in 36 high-risk patients with acute calculous gallbladder disease. At cholecystostomy, the fundus of the gallbladder was sutured to the anterior abdominal wall, permitting early percutaneous stone removal through the short surgical tract. All gallstones were removed in 31 of 36 patients, for an overall success rate of 86%. The success rate was 97% for gallbladder stones, 86% for cystic duct stones, and 63% for common bile duct stones which were removed by traversing the cystic duct. There were no deaths or serious complications

    Although elderly patients with thoracic disease were considered to be poor candidates for thoracotomy before, recent advances in preoperative and postoperative care as well as surgical techniques have improved outcomes of thoracotomies in this patient group. The aim of this study was to investigate surgical risk factors and results in elderly patients (aged > or =70 years) with thoracic empyema. Seventy-one elderly patients with empyema thoracis were enrolled and evaluated from July 2000 to April 2003. The following characteristics and clinical data were analysed: age, sex, aetiology of empyema, comorbid diseases, preoperative conditions, postoperative days of intubation, length of hospital stay after surgery, complications and mortality. Surgical intervention, including total pneumonolysis and evacuation of the pleura empyema cavity, was carried out in all patients. Possible influent risk factors on the outcome were analysed. The sample group included 54 men and 17 women with an average age of 76.8 years. The causes of empyema included parapneumonic effusion (n = 43), lung abscess (n = 8), necrotizing pneumonitis (n = 8), malignancy (n = 5), cirrhosis (n = 2), oesophageal perforation (n = 2), post-traumatic empyema (n = 2) and post-thoracotomy complication (n = 1). The 30-day mortality rate was 11.3% and the in-hospital mortality rate was 18.3% (13 of 71). Mean follow up was 9.4 months and mean duration of postoperative hospitalization was 35.8 days. Analysis of risk factors showed that patients with necrotizing pneumonitis or abscess had the highest mortality rate (10 of 18, 62.6%). The second highest risk factor was preoperative intubation or ventilator-dependency (8 of 18, 44.4%). This study presents the clinical features and outcomes of 71 elderly patients with empyema thoracis who underwent surgical treatment. The 30-day surgical mortality rate was 11.3%. Significant risk factors in elderly patients with empyema thoracis were necrotizing pneumonitis, abscess

    To reduce the incidence of urinary tract infection, Surgical Care Improvement Project 9 mandates the removal of urinary catheters within 48 hours postoperatively. In patients with thoracic epidural anesthesia, we sought to determine the rate of catheter reinsertion, the complications of reinsertion, and the factors associated with reinsertion. We conducted a prospective observational study of consecutive patients undergoing major pulmonary or esophageal resection with thoracic epidural analgesia over a 2-year period. As per Surgical Care Improvement Project 9, all urinary catheters were removed within 48 hours postoperatively. Excluded were patients with chronic indwelling catheter, patients with urostomy, and patients requiring continued strict urine output monitoring. Multivariable logistic regression analysis was used to identify independent risk factors for urinary catheter reinsertion. Thirteen patients met exclusion criteria. Of the 275 patients evaluated, 60 (21.8%) required reinsertion of urinary catheter. There was no difference in the urinary tract infection rate between patients requiring reinsertion (1/60 [1.7%]) versus patients not requiring reinsertion (1/215 [0.5%], P = .389). Urethral trauma during reinsertion was seen in 1 of 60 patients (1.7%). After reinsertion, discharge with urinary catheter was required in 4 of 60 patients (6.7%). Multivariable logistic regression analysis found esophagectomy, lower body mass index, and benign prostatic hypertrophy to be independent risk factors associated with catheter reinsertion after early removal in the presence of thoracic epidural analgesia. When applying Surgical Care Improvement Project 9 to patients undergoing thoracic procedures with thoracic epidural analgesia, consideration to delayed removal of urinary catheter may be warranted in patients with multiple risk factors for reinsertion.

    The aim of this study was to assess the usefulness of clinical-administrative databases for the development of risk adjustment in the assessment of adverse events in surgical patients. The study was conducted at the Hospital of Navarra, a tertiary teaching hospital in northern Spain. We studied 1602 hospitalizations of surgical patients from 2008 to 2010. We analysed 40 comorbidity variables included in the National Surgical Quality Improvement (NSQIP) Program of the American College of Surgeons using 2 sources of information: The clinical and administrative database (CADB) and the data extracted from the complete clinical records (CR), which was considered the gold standard. Variables were catalogued according to compliance with the established criteria: sensitivity, positive predictive value and kappa coefficient >0.6. The average number of comorbidities per study participant was 1.6 using the CR and 0.95 based on CADB (p<.0001). Thirteen types of comorbidities (accounting for 8% of the comorbidities detected in the CR) were not identified when the CADB was the source of information. Five of the 27 remaining comorbidities complied with the 3 established criteria; 2 pathologies fulfilled 2 criteria, whereas 11 fulfilled 1, and 9 did not fulfil any criterion. CADB detected prevalent comorbidities such as comorbid hypertension and diabetes. However, the CABD did not provide enough information to assess the variables needed to perform the risk adjustment proposed by the NSQIP for the assessment of adverse events in surgical patients.

    Full Text Available Background: Patients with liver cirrhosis have high surgical risks due to malnutrition, impaired immunity, coagulopathy, and encephalopathy. However, there is no information in English literature about the results of liver cirrhotic patients who underwent instrumented lumbar surgery. The purpose of this study is to report the perioperative complications, clinical outcomes and determine the surgical risk factors in cirrhotic patients. Methods: We retrospectively reviewed 29 patients with liver cirrhosis who underwent instrumented lumbar surgery between 1997 and 2009. The hepatic functional reserves of the patients were recorded according to the Child-Turcotte-Pugh scoring system. Besides, fourteen other variables and perioperative complications were also collected. To determine the risks, we divided the patients into two groups according to whether or not perioperative complications developed. Results: Of the 29 patients, 22 (76% belonged to Child class A and 7 (24% belonged to Child class B. Twelve patients developed one or more complications. Patients with Child class B carried a significantly higher incidence of complications than those with Child class A (p = 0.011. In the Child class A group, patients with 6 points had a significantly higher incidence of complications than those with 5 points (p = 0.025. A low level of albumin was significantly associated with higher risk, and a similar trend was also noted for the presence of ascites although statistical difference was not reached. Conclusion: The study concludes that patients with liver cirrhosis who have undergone instrumented lumbar surgery carry a high risk of developing perioperative complications, especially in those with a Child-Turcotte-Pugh score of 6 or more.

    Neuroblastoma is the second most common solid pediatric tumor and the most common cancer to be detected in children younger than 12 months of age. To date, 2 different staging systems describe the extent of the disease: the International Neuroblastoma Staging System (INSS) and the International Neuroblastoma Risk Group Staging System (INRGSS). The INRGSS-system is characterized by the presence or absence of so called image-defined risk factors (IDRFs), which are described as surgical risk factors. We hypothesized that IDRFs correlate with surgical complications, surgical radicality, local recurrence and overall survival (OS). Between 2003 and 2010, 102 patients had neuroblastoma surgery performed in our department. We analyzed medical records for IDRF-status and above named data. 16 patients were IDRF-negative, whereas 86 patients showed one or more IDRF. Intra- or postoperative complications have been reported in 21 patients (21%). 19 of them showed one or more IDRF and 2 patients were IDRF-negative (p=n.s.). Patients who suffered from intra- or postoperative complications demonstrated a decreased OS (p=0.011). Statistical analysis revealed an inverse correlation between the extent of macroscopical removal and IDRF-status (p=0.001). Furthermore, the number of IDRFs were associated with a decreased likelihood of radical tumor resection (p<0.001). 19 patients had local recurrence; all of them were IDRF-positive (p=0.037). Pediatric surgeons should consider IDRFs as a useful tool for risk assessment and therefore planning for neuroblastoma surgery. © Georg Thieme Verlag KG Stuttgart · New York.

    National guidance states that all patients having emergency surgery should have a mortality risk assessment calculated on admission so that the 'high risk' patient can receive the appropriate seniority and level of care. We aimed to assess if peri-operative risk scoring tools could accurately calculate mortality and morbidity risk. Mortality risk scores for 86 consecutive emergency laparotomies, were calculated using pre-operative (ASA, Lee index) and post-operative (POSSUM, P-POSSUM and CR-POSSUM) risk calculation tools. Morbidity risk scores were calculated using the POSSUM predicted morbidity and compared against actual morbidity according to the Clavien-Dindo classification. The actual mortality was 10.5%. The average predicted risk scores for all laparotomies were: ASA 26.5%, Lee Index 2.5%, POSSUM 29.5%, P-POSSUM 18.5%, CR-POSSUM 10.5%. Complications occurred following 67 laparotomies (78%). The majority (51%) of complications were classified as Clavien-Dindo grade 2-3 (non-life-threatening). Patients having a POSSUM morbidity risk of greater than 50% developed significantly more life-threatening complications (CD 4-5) compared with those who predicted less than or equal to 50% morbidity risk (P = 0.01). Pre-operative risk stratification remains a challenge because the Lee Index under-predicts and ASA over-predicts mortality risk. Post-operative risk scoring using the CR-POSSUM is more accurate and we suggest can be used to identify patients who require intensive care post-operatively. In the absence of accurate risk scoring tools that can be used on admission to hospital it is not possible to reliably audit the achievement of national standards of care for the 'high-risk' patient.

    Identification of risk factors for requiring transfusions during surgery for colorectal cancer may lead to preventive actions or alternative measures, towards decreasing the use of blood components in these procedures, and also rationalization of resources use in hemotherapy services. This was a retrospective case-control study using data from 383 patients who were treated surgically for colorectal adenocarcinoma at 'Fundação Pio XII', in Barretos-SP, Brazil, between 1999 and 2003. To recognize significant risk factors for requiring intraoperative blood transfusion in colorectal cancer surgical procedures. Univariate analyses were performed using Fisher's exact test or the chi-squared test for dichotomous variables and Student's t test for continuous variables, followed by multivariate analysis using multiple logistic regression. In the univariate analyses, height (P = 0.06), glycemia (P = 0.05), previous abdominal or pelvic surgery (P = 0.031), abdominoperineal surgery (Pblood transfusion.

    Full Text Available Aleksandra Kołtuniuk, Joanna Rosińczuk Department of Nervous System Diseases, Faculty of Health Science, Wroclaw Medical University, Wroclaw, Poland Background: Cardiovascular diseases (CVDs are the leading cause of mortality among adults in Poland. A number of risk factors have significant influence on CVD incidence. Early identification of risk factors related to our lifestyle facilitates taking proper actions aiming at the reduction of their negative impact on health.Aim: The aim of the study was to compare the prevalence of CVD risk factors between patients aged over 65 years and patients of other age groups in surgical wards.Material and methods: The study was conducted for assessment and finding the distribution of major risk factors of CVD among 420 patients aged 18–84 years who were hospitalized in surgical wards. Interview, anthropometric measurements, blood pressure, and fasting blood tests for biochemical analysis were conducted in all subjects. Statistical analysis of the material was performed using Student’s t-test, chi-square test, Fisher’s exact test, Mann–Whitney U-test, and analysis of variance.Results: While abdominal obesity (83.3%, overweight and obesity (68%, hypertension (65.1%, hypercholesterolemia (33.3%, and low level of physical activity (29.1% were the most common CVD risk factors among patients over 65 years old, abdominal obesity (36.2%, overweight and obesity (36.1%, and current smoking were the most common CVD risk factors among patients up to the age of 35. In the age group over 65, the least prevalent risk factors for CVD were diabetes mellitus (14.8%, depressive episodes (13.6%, abuse of alcohol (11.4%, and smoking (7.8%. In the group under 35 years, we have not reported any cases of hypercholesterolemia and a lesser number of patients suffered from diabetes and HTN.Conclusion: Distribution of the major risk factors for CVD is quite high in the adult population, especially in the age group over 65

    A simplified minimally invasive mitral valve surgery (MIMVS) approach avoiding cross-clamping and cardioplegic myocardial arrest using a small (5 cm) right antero-lateral incision was developed. We hypothesized that, in high-risk patients and in patients with prior sternotomy, this approach would yield superior results compared to those predicted by the Society of Thoracic Surgeons (STS) algorithm for standard median sternotomy mitral valve surgery. Five hundred and four consecutive patients (249 males/255 females), median age 65 years (range 20-92 years) underwent MIMVS between 1/06 and 8/09. Median preoperative New York Heart Association function class was 3 (range 1-4). Eighty-two (16%) patients had an ejection fraction ≤35%. Forty-seven (9%) had a STS predicted mortality ≥10%. Under cold fibrillatory arrest (median temperature 28°C) without aortic cross-clamp, mitral valve repair (224/504, 44%) or replacement (280/504, 56%) was performed. Thirty-day mortality for the entire cohort was 2.2% (11/504). In patients with a STS predicted mortality ≥ 10% (range 10%-67%), the observed 30-day mortality was 4% (2/47), lower than the mean STS predicted mortality of 20%. Morbidity in this high-risk group was equally low: 1 of 47 (2%) patients underwent reexploration for bleeding, 1 of 47 (2%) patients suffered a permanent neurologic deficit, none had wound infection. The median length of stay was 8 days (range 1-68 days). This study demonstrates that MIMVS without aortic cross-clamp is reproducible with low mortality and morbidity rates. This approach expands the surgical options for high-risk patients and yields to superior results than the conventional median sternotomy approach.

  18. Cervical spine surgery performed in ambulatory surgical centers: Are patients being put at increased risk?

    Spine surgeons are being increasingly encouraged to perform cervical operations in outpatient ambulatory surgical centers (ASC). However, some studies/data coming out of these centers are provided by spine surgeons who are part or full owners/shareholders. In Florida, for example, there was a 50% increase in ASC (5349) established between 2000-2007; physicians had a stake (invested) in 83%, and outright owned 43% of ASC. Data regarding "excessive" surgery by ASC surgeon-owners from Idaho followed shortly thereafter. The risks/complications attributed to 3279 cervical spine operations performed in 6 ASC studies were reviewed. Several studies claimed 99% discharge rates the day of the surgery. They also claimed major complications were "picked up" within the average postoperative observation window (e.g., varying from 4-23 hours), allowing for appropriate treatment without further sequelae. Morbidity rates for outpatient cervical spine ASC studies (e.g. some with conflicts of interest) varied up to 0.8-6%, whereas morbidity rates for 3 inpatient cervical studies ranged up to 19.3%. For both groups, morbidity included postoperative dysphagia, epidural hematomas, neck swelling, vocal cord paralysis, and neurological deterioration. Although we have no clear documentation as to their safety, "excessive" and progressively complex cervical surgical procedures are increasingly being performed in ASC. Furthermore, we cannot rely upon ASC-based data. At least some demonstrate an inherent conflict of interest and do not veridically report major morbidity/mortality rates for outpatient procedures. For now, cervical spine surgery performed in ASC would appear to be putting patients at increased risk for the benefit of their surgeon-owners.

    To evaluate the technical feasibility and clinical efficacy of percutaneous transhepatic cholecystolithotomy under fluoroscopic guidance in high-risk surgical patients with acute cholecystitis. Sixty-three consecutive patients of high surgical risk with acute calculous cholecystitis underwent percutaneous transhepatic gallstone removal under conscious sedation. The stones were extracted through the 12-Fr sheath using a Wittich nitinol stone basket under fluoroscopic guidance on three days after performing a percutaneous cholecystostomy. Large or hard stones were fragmented using either the snare guide wire technique or the metallic cannula technique. Gallstones were successfully removed from 59 of the 63 patients (94%). Reasons for stone removal failure included the inability to grasp a large stone in two patients, and the loss of tract during the procedure in two patients with a contracted gallbladder. The mean hospitalization duration was 7.3 days for acute cholecystitis patients and 9.4 days for gallbladder empyema patients. Bile peritonitis requiring percutaneous drainage developed in two patients. No symptomatic recurrence occurred during follow-up (mean, 608.3 days). Fluoroscopy-guided percutaneous gallstone removal using a 12-Fr sheath is technically feasible and clinically effective in high-risk surgical patients with acute cholecystitis

    As the most suitable approach for preventing bisphosphonate-related osteonecrosis of the jaw (BRONJ) in patients undergoing surgical tooth extraction is still under discussion, the present study evaluates the incidence of BRONJ after surgical tooth extraction using a standardized surgical protocol in combination with an adjuvant perioperative treatment setting in patients who are at high-risk for developing BRONJ. High-risk patients were defined as patients who received intravenous bisphosphonate (BP) due to a malignant disease. All teeth were removed using a standardized surgical protocol. The perioperative adjuvant treatment included intravenous antibiotic prophylaxis starting at least 24 h before surgery, a gastric feeding tube and mouth rinses with chlorhexidine (0.12%) three times a day. In the follow-up period patients were examined every 4 weeks for the development of BRONJ. Minimum follow-up was 12 weeks. In 61 patients a total number of 184 teeth were removed from 102 separate extraction sites. In eight patients (13.1%) BRONJ developed during the follow-up. A higher risk for developing BRONJ was found in patients where an additional osteotomy was necessary (21.4% vs. 8.0%; p = 0.0577), especially for an osteotomy of the mandible (33.3% vs. 7.3%; p = 0.0268). Parameters including duration of intravenous antibiotic prophylaxis, the use of a gastric feeding tube and the duration of intravenous BP therapy showed no statistical impact on the development of BRONJ. Furthermore, patients currently undergoing intravenous BP therapy showed no higher risk for BRONJ compared with patients who have paused or completed their intravenous BP therapy (p = 0.4232). This study presents a protocol for surgical tooth extraction in high-risk BP patients in combination with a perioperative adjuvant treatment setting, which reduced the risk for postoperative BRONJ to a minimum. However, the risk for BRONJ increases significantly if an additional osteotomy is necessary

    Inhaled milrinone (iMil) has been used for the treatment of pulmonary hypertension (PH) but its efficacy, safety, and prophylactic effects in facilitating separation from cardiopulmonary bypass (CPB) and preventing right ventricular (RV) dysfunction have not yet been evaluated in a clinical trial. The purpose of this study was to investigate if iMil administered before CPB would be superior to placebo in facilitating separation from CPB. High-risk cardiac surgical patients with PH were randomized to receive iMil or placebo after the induction of anesthesia and before CPB. Hemodynamic parameters and RV function were evaluated by means of pulmonary artery catheterization and transesophageal echocardiography. The groups were compared for the primary outcome of the level of difficulty in weaning from CPB. Among the secondary outcomes examined were the reduction in the severity of PH, the incidence of RV failure, and mortality. Of the 124 patients randomized, the mean (standard deviation [SD]) EuroSCORE II was 8.0 (2.6), and the baseline mean (SD) systolic pulmonary artery pressure (SPAP) was 53 (9) mmHg. The use of iMil was associated with increases in cardiac output (P = 0.03) and a reduction in SPAP (P = 0.04) with no systemic hypotension. Nevertheless, there was no difference in the combined incidence of difficult or complex separation from CPB between the iMil and control groups (30% vs 28%, respectively; absolute difference, 2%; 95% confidence interval [CI], -14 to 18; P = 0.78). There was also no difference in RV failure between the iMil and control groups (15% vs 14%, respectively; difference, 1%; 95% CI, -13 to 12; P = 0.94). Mortality was increased in patients with RV failure vs those without (22% vs 2%, respectively; P < 0.001). In high-risk cardiac surgery patients with PH, the prophylactic use of iMil was associated with favourable hemodynamic effects that did not translate into improvement of clinically relevant endpoints. This trial was registered at

    Whether the fraction of inspired oxygen (F I O 2 ) influences the risk of surgical site infection (SSI) is controversial. The World Health Organization and the World Federation of Societies of Anesthesiologists offer conflicting recommendations. In this study, we evaluate simultaneously three different definitions of F I O 2 exposure and the risk of SSI in a large surgical population. Patients with clean (type 1) surgical incisions who developed superficial and deep organ/space SSI within 30 days after surgery from January 2003 through December 2012 in five surgical specialties were matched to specialty-specific controls. Fraction of inspired oxygen exposure was defined as (1) nadir F I O 2 , (2) percentage of operative time with F I O 2 greater than 50%, and (3) cumulative hyperoxia exposure, calculated as the area under the curve (AUC) of F I O 2 by time for the duration in which F I O 2 greater than 50%. Stratified univariable and multivariable logistic regression models tested associations between F I O 2 and SSI. One thousand two hundred fifty cases of SSI were matched to 3,248 controls. Increased oxygen exposure, by any of the three measures, was not associated with the outcome of any SSI in a multivariable logistic regression model. Elevated body mass index (BMI; 35+ vs. operative oxygen exposure was associated with higher odds of SSI in the neurosurgical and spine populations. Increased intra-operative inspired fraction of oxygen was not associated with a reduction in SSI. These findings do not support the practice of increasing F I O 2 for the purpose of SSI reduction in patients with clean surgical incisions.

    Full Text Available Background: High prevalence of malnutrition along with the risk for the development of malnutrition in hospitalised children has been reported. However, this problem remains largely unrecognised by healthcare workers. Aims: To determine the prevalence of malnutrition and effectiveness of STRONGkids nutritional risk screening (NRS tool in the identification of malnutrition risk among pediatric surgical patients. Study Design: Cross-sectional study. Methods: A total of 494 pediatric surgical patients (median age 59 months, 75.8% males were included in this prospective study conducted over 3 months. SD-scores 60 months (13.4 vs. 6.6%, p=0.012. Chronic malnutrition was identified in 23 (4.6% of patients with no significant difference between age groups. There were 7 (1.4% children with coexistent acute and chronic malnutrition. The STRONGkids tool revealed that 35.7% of patients were either in the moderate or high risk group for malnutrition. Malnutrition, as revealed by anthropometric measurements, was more likely in the presence of gastrointestinal (26.9%, p=0.004 and inguinoscrotal/penile surgery (4.0%, p=0.031, co-morbidities affecting nutritional status (p<0.001 and inpatient admissions (p=0.014. Among patients categorized as low risk for malnutrition, there were more outpatients than inpatients (89.3 vs. 10.7%, p<0.001 and more elective surgery cases than emergency surgery cases (93.4 vs. 6.6%, p<0.001. Conclusion: Providing data on the prevalence of malnutrition and risk of malnutrition in a prospectively recruited group of hospitalised pediatric surgical patients, the data acquired in the present study emphasise the need to raise clinician’s awareness about the importance of nutritional status assessment among hospitalised pediatric patients and the benefits of identifying patients at the risk of nutritional depletion before malnutrition occurs. Our findings support the use of the STRONGkids tool among pediatric surgical patients to

    intraluminal stent implantation is an alternative. Objective: to analyze the impact of percutaneous implantation of aortic stents in high-risk surgical patients with a minimum of one y ear follow-up. Method: Descriptive study conducted from December 2005 to March 2010 which included 125 patients with thoracic or abdominal aortic aneurysm, meeting surgical criteria by its diameter and that were rejected from surgery due to their high risk. The outcomes were intraoperative death from any cause and aneurysm-related at one, six and twelve months. Complications were defined as vascular occurred during the first thirty days. Results: Abdominal aneurysm was more frequent (70.4%. The overall mortality at 25.7 months follow-up was 14.8%. Of this percentage, 5.2% died from causes related to the aneurysm. One patient died during surgery. 4.3% were reoperated for leaks. There was higher aneurysm-related mortality in the thoracic (14.7 vs. 1.2% p = 0.003 and a trend in those of larger diameter (6.9 vs. 5.7 cm p = 0.210. There was no association between mortality and diabetes mellitus, smoking, heart disease, hypertension or dyslipidemia. Conclusions: aneurysm-related mortality in patients undergoing aortic stent graft is low. Mortality was associated with thoracic aneurysm and to its greater diameter. Complications did not imply an increase in mortality. In conclusion, in patients with aortic aneurysm and high surgical risk rejected for open surgery, percutaneous approach is a safe and effective treatment in a medium-term follow-up.

    Although several studies have been conducted on the role of surgery in localized neuroblastoma, the impact of surgical timing and extent of primary tumor resection on outcome in high-risk patients remains controversial. Patients from the German neuroblastoma trial NB97 with localized neuroblastoma INSS stage 1-3 age > 18 months were included for retrospective analysis. Imaging reports were reviewed by two independent physicians for Image Defined Risk Factors (IDRF). Operation notes and corresponding imaging reports were analyzed for surgical radicality. The extent of tumor resection was classified as complete resection (95-100%), gross total resection (90-95%), incomplete resection (50-90%), and biopsy (Neuroblastoma Risk Group (INRG) staging system. Survival curves were estimated according to the method of Kaplan and Meier and compared by the log-rank test. A total of 179 patients were included in this study. 77 patients underwent more than one primary tumor operation. After best surgery, 68.7% of patients achieved complete resection of the primary tumor, 16.8% gross total resection, 14.0% incomplete surgery, and 0.5% biopsy only. The cumulative complication rate was 20.3% and the surgery associated mortality rate was 1.1%. Image defined risk factors (IDRF) predicted the extent of resection. Patients with complete resection had a better local-progression-free survival (LPFS), event-free survival (EFS) and OS (overall survival) than the other groups. Subgroup analyses showed better EFS, LPFS and OS for patients with complete resection in INRG high-risk patients. Multivariable analyses revealed resection (complete vs. other), and MYCN (non-amplified vs. amplified) as independent prognostic factors for EFS, LPFS and OS. In patients with localized neuroblastoma age 18 months or older, especially in INRG high-risk patients harboring MYCN amplification, extended surgery of the primary tumor site improved local control rate and survival with an acceptable risk of

    Purpose: Recent prospective data have shown that patients with solitary or oligometastatic disease to the brain may be treated with upfront stereotactic radiosurgery (SRS) with deferral of whole-brain radiation therapy (WBRT). This has been extrapolated to the treatment of patients with resected lesions. The aim of this study was to assess the risk of leptomeningeal disease (LMD) in patients treated with SRS to the postsurgical resection cavity for brain metastases compared with patients treated with SRS to intact metastases. Methods and Materials: Four hundred sixty-five patients treated with SRS without upfront WBRT at a single institution were identified; 330 of these with at least 3 months' follow-up were included in this analysis. One hundred twelve patients had undergone surgical resection of at least 1 lesion before SRS compared with 218 treated for intact metastases. Time to LMD and overall survival (OS) time were estimated from date of radiosurgery, and LMD was analyzed by the use of cumulative incidence method with death as a competing risk. Univariate and multivariate analyses were performed with competing risk regression to determine whether various clinical factors predicted for LMD. Results: With a median follow-up time of 9.0 months, 39 patients (12%) experienced LMD at a median of 6.0 months after SRS. At 1 year, the cumulative incidence of LMD, with death as a competing risk, was 5.2% for the patients without surgical resection versus 16.9% for those treated with surgery (Gray test, P<.01). On multivariate analysis, prior surgical resection (P<.01) and breast cancer primary (P=.03) were significant predictors of LMD development. The median OS times for patients undergoing surgery compared with SRS alone were 12.9 and 10.6 months, respectively (log-rank P=.06). Conclusions: In patients undergoing SRS with deferral of upfront WBRT for intracranial metastatic disease, prior surgical resection and breast cancer primary are associated with an

    Full Text Available Denise Visco Eyes of York Cataract & Laser Center, York, PA, USA Purpose: To evaluate the effect of intracameral phenylephrine/ketorolac (1%/0.3% during cataract surgery on the use of iris fixation ring and surgical time in patients with poor pupil dilation (≤5.0 mm or intraoperative floppy iris syndrome (IFIS. Setting: Private practice outpatient surgical center. Design: This retrospective analysis was conducted from January 1, 2014 to October 7, 2015. Materials and methods: The use of iris fixation rings was evaluated in a retrospective analysis of 46 patients who underwent cataract surgery from January 1, 2014, to October 7, 2015, and who were identified before surgery to be at risk for intraoperative miosis. The qualifying factors were presurgical examination of pupil dilation ≤5.0 mm after being administered topical tropicamide 1% and phenylephrine 2.5% or history of IFIS during surgery in the fellow eye. All patients received a 2-day preoperative course of topical nonsteroidal anti-inflammatory drugs (NSAIDs and day-of-surgery preoperative dilation using topical cyclopentolate 1%, tropicamide 1%, and phenylephrine 10%. Phenylephrine/ketorolac 1%/0.3% (Omidria® or epinephrine 1:1,000 with sulfites was added to the ophthalmic irrigation solution and delivered intracamerally at the start of the procedure and throughout surgery. The use of iris fixation rings and surgical time for each patient were captured for each group. Results: Eighteen (50% of the patients in the epinephrine group and no patients in the phenylephrine/ketorolac group required iris fixation ring insertion to maintain pupil dilation or to control IFIS (p=0.0034. Mean surgical time was significantly shorter in the group of patients who received phenylephrine/ketorolac (p=0.0068. Conclusion: In this retrospective cohort analysis of patients with poorly dilated pupils and/or IFIS, the use of intracameral phenylephrine/ketorolac in patients at risk for intraoperative

    Considerable blood product support is administered to the cardiac surgery population. Due to the multifactorial etiology of bleeding in the cardiac bypass patient, blood products frequently and empirically are infused to correct bleeding, with varying success. Several studies have demonstrated the benefit of algorithm-guided transfusion in reducing blood loss, transfusion exposure, or rate of surgical re-exploration for bleeding. Some transfusion algorithms also incorporate laboratory-based decision points in their guidelines. Despite published success with standardized transfusion practices, generalized change in blood use has not been realized, and it is evident that current laboratory-guided hemostasis measures are inadequate to define and address the bleeding etiology in these patients.

    Full Text Available Aim: In association with increasing life expectancy, the number of elderly individuals undergoing coronary bypass grafting (CABG and additional cardiac surgical procedures are increasing. In this study, we evaluated the effects of additional cardiac procedures and preoperative risk factors for postoperative mortality and morbidity in patients 80 years of age and older. Methods: The records of 29 patients aged 80 years and older (82.86±2.91 who had undergone coronary bypass surgery in the department of cardiac surgery between September 2009 and June 2012, were retrospectively reviewed. The subjects were divided into two groups: group 1 included the patients who had undergone CABG, group 2 consisted of those who had undergone CABG and additional cardiac procedures. Results: The mean age of the patients [14 male (48.3% 15 female (51.7%] was 82.86±2.91 years. The left internal thoracic artery was harvested for all patients. The mean number of graft per patient was 3.07±0.95. Carotid endarterectomy was performed in 3 patients before CABG. CABG and aortic valve replacement were performed in 1 patient. CABG, mitral valve replacement ant tricuspid plasty were performed in another patient. Furthermore, in one patient, abdominal aortic graft replacement due to ruptured abdominal aortic aneurysm and CABG was performed at the same session. The mean EuroSCORE was 5.06±5.16. Postoperative 30 days mortality was 6.8%, and the mean length of stay in hospital was 10.45±8.18 days. Conclusion: Coronary bypass surgery is an acceptable treatment method in patients 80 years of age and older. Although additional cardiac procedures may increase sugical risks, they can be successfully performed. (The Me­di­cal Bul­le­tin of Ha­se­ki 2014; 52: 14-8

    Standard treatment for operable patients with single peripheral lung metastases is metastasectomy. We report mature CyberKnife outcomes for high-risk surgical patients with biopsy proven single peripheral lung metastases. Twenty-four patients (median age 73 years) with a mean maximum tumor diameter of 2.5 cm (range, 0.8–4.5 cm) were treated over a 6-year period extending from September 2004 to September 2010 and followed for a minimum of 1 year or until death. A mean dose of 52 Gy (range, 45–60 Gy) was delivered to the prescription isodose line in three fractions over a 3–11 day period (mean, 7 days). At a median follow-up of 20 months, the 2-year Kaplan–Meier local control and overall survival rates were 87 and 50%, respectively. CyberKnife with fiducial tracking is an effective treatment for high-risk surgical patients with single small peripheral lung metastases. Trials comparing CyberKnife with metastasectomy for operable patients are necessary to confirm equivalence.

    In a retrospective study, we compared two groups of consecutive patients operated by the same team during the year 2000 for coronary artery disease with the use of extracorporeal circulation (group 1, n=230) or on the beating heart using the Octopus II plus stabiliser (group 2, n=228). High-risk patients were identified by a EuroSCORE plus 6. EuroSCORE definitions and predicted risk models were utilized to compare the variables of the groups. There were no significant differences between the preoperative variables of the groups in age, gender, left ventricular function, diabetes and peripheral vascular and renal disease as is indicated by the Euroscore (resp. 4.7/5.1 p=0.107). Calcification of the ascending aorta and chronic obstructive lung disease were statistically significant more prevalent in the beating heart group. No differences in preoperative variables in the high-risk patients group (Euroscore 8.5/8.1 p=0.356) except for calcification of the ascending aorta. All patients underwent a full revascularisation through a midline sternotomy. Significant more distal anastomoses were performed in group 1 (3.7 per patient (1-6)) with regard to group 2 (2.9 per patient (1-6)). Anesthesia, postoperative treatment and follow up were equal for both groups. A significant lower incidence of atrial fibrillation (p=0.010), shorter ICU stay (p=0.031) and renal insufficiency (p=0.033) was reported in group 2. In the low risk group, we could not diagnose any difference between the two groups, except for atrial fibrillation. The benefits of the beating heart surgery however were more pronounced in the high-risk patient as is indicated by a significant reduction of the ICU stay by 1 day (3.5d/2.5d (p=0.028)), better preservation of the renal function (p=0.017) and a significant reduction of the length of hospital stay by more than two days (p=0.040).

    To assess the efficacy and safety of ultrasound guided percutaneous cholecystostomy (PC) in the treatment of acute cholecystitis in a well-defined high risk patients under general anesthesia. The data of 27 consecutive patients who underwent percutaneous transhepatic cholecystostomy for the management of acute cholecystitis from January 1999 to June 2003 was retrospectively evaluated. All of the patients had both clinical and sonographic signs of acute cholecystitis and had comorbid diseases. Ultrasound revealed gallbladder stones in 25 patients and acalculous cholecystitis in two patients. Cholecystostomy catheters were removed 14-32 d (mean 23 d) after the procedure in cases where complete regression of all symptoms was achieved. There were statistically significant reductions in leukocytosis, (13.7 x 10(3)+/-1.3 x 10(3) microg/L vs 13 x 10(3)+/-1 x 10(3) microg/L, P extraction was performed successfully with endoscopic retrograde cholangio-pancreatography (ERCP) in three patients. After cholecystostomy, 5 (18%) patients underwent delayed cholecystectomy without any complications. Three out of 22 patients were admitted with recurrent acute cholecystitis during the follow-up and recovered with medical treatment. Catheter dislodgement occurred in three patients spontaneously, and two of them were managed by reinsertion of the catheter. As an alternative to surgery, percutaneous cholecystostomy seems to be a safe method in critically ill patients with acute cholecystitis and can be performed with low mortality and morbidity. Delayed cholecystectomy and ERCP, if needed, can be performed after the acute period has been resolved by percutaneous cholecystostomy.

    Prior research has provided inconsistent data regarding the risk factors associated with complications from arterial cannulation. The goal of this study was to clearly define the incidence and risks factors associated with arterial cannulation complications. After obtaining institutional review board approval, all patients requiring arterial line placement with documentation were included in this retrospective study between January 1, 2006, and December 31, 2012. Leveraging two robust data warehouses, the Perioperative DataMart and the Mayo Clinic Life Silences System, the authors cross-matched arterial line cannulation with a documented vascular consult, neurologic consult, infection, or return to surgery within 30 days in order to identify the initial patient population. A total of 62,626 arterial lines were placed in 57,787 patients, and 90.1% of the catheters placed were 20-gauge catheters. The radial artery was cannulated in 94.5% of patients. A total of 21 patients were identified as having experienced vascular complications or nerve injuries, resulting in a complication rate of 3.4 per 10,000 (95% CI, 2.1 to 5.1). Cardiac surgery had the largest number of catheters placed (n = 15,419) with 12 complications (complication rate = 7.8 per 10,000; 95% CI, 4.0 to 13.6). The rate of complications differed significantly (P < 0.001) across the three most common catheter sizes (2.7 per 10,000 [95% CI, 1.5 to 4.4] for 20 gauge, 17.2 per 10,000 [95% CI, 4.7 to 43.9] for 18 gauge, and 9.4 per 10,000 [95% CI, 1.1 to 34.1] for 5 French). In a large retrospective study, the authors document a very low rate of complications with arterial line placement.

    AIM: To assess the efficacy and safety of ultrasound guided percutaneous cholecystostomy (PC) in the treatment of acute cholecystitis in a well-defined high risk patients under general anesthesia. METHODS: The data of 27 consecutive patients who underwent percutaneous transhepatic cholecystostomy for the management of acute cholecystitis from January 1999 to June 2003 was retrospectively evaluated. All of the patients had both clinical and sonographic signs of acute cholecystitis and had comorbid diseases. RESULTS: Ultrasound revealed gallbladder stones in 25 patients and acalculous cholecystitis in two patients. Cholecystostomy catheters were removed 14-32 d (mean 23 d) after the procedure in cases where complete regression of all symptoms was achieved. There were statistically significant reductions in leukocytosis, (13.7 × 103 ± 1.3 × 103 μg/L vs 13 × 103 ± 1 × 103 μg/L, P < 0.05 for 24 h after PC; 13.7 × 103 ± 1.3 × 103 μg/L vs 8.3 × 103 ± 1.2 × 103 μg/L, P < 0.0001 for 72 h after PC), C -reactive protein (51.2 ± 18.5 mg/L vs 27.3 ± 10.4 mg/L, P < 0.05 for 24 h after PC; 51.2 ± 18.5 mg/L vs 5.4 ± 1.5 mg/L, P < 0.0001 for 72 h after PC), and fever (38 ± 0.35°C vs 37.3 ± 0.32°C, P < 0.05 for 24 h after PC; 38 ± 0.35°C vs 36.9 ± 0.15°C, P < 0.0001 for 72 h after PC). Sphincterotomy and stone extraction was performed successfully with endoscopic retrograde cholangio-pancreatography (ERCP) in three patients. After cholecystostomy, 5 (18%) patients underwent delayed cholecystectomy without any complications. Three out of 22 patients were admitted with recurrent acute cholecystitis during the follow-up and recovered with medical treatment. Catheter dislodgement occurred in three patients spontaneously, and two of them were managed by reinsertion of the catheter. CONCLUSION: As an alternative to surgery, percutan-eous cholecystostomy seems to be a safe method in critically ill patients with acute cholecystitis and can be performed with low

    Pseudoaneurysm of the ascending aorta is an uncommon pathology and a challenge in high-risk patients who undergo conventional surgery because of high operative morbidity and mortality. Endovascular exclusion of an aortic pseudoaneurysm using an endoprosthesis is a less invasive approach, but few such cases have been reported. Moreover, the use of this approach poses unique therapeutic challenges because there is no specific endoprosthesis for ascending aortic repair, particularly to treat patients with previous coronary artery bypass graft (CABG). We describe the case of a 74-year-old patient who had undergone CABG and later presented with an iatrogenic ascending aortic pseudoaneurysm that occurred during an angiography. This patient was at very high risk for surgical treatment and, therefore, an endovascular approach was adopted: percutaneous coronary intervention for the left main coronary artery, left anterior descending and left circumflex native coronary arteries followed by endovascular endoprosthesis deployment in the ascending aorta to exclude the pseudoaneurysm. Both procedures were successfully performed, and the patient was discharged without complications 4 days later. At 5 months' clinical follow-up, his clinical condition was good and he had no complications. Copyright © 2011 Wiley-Liss, Inc.

    The primary aim of this study was to determine whether orthopaedic trauma patients receive appropriate antibiotic prophylaxis keeping in view the results of their MRSA screening. The secondary aim was to analyse the risk of developing MRSA surgical site infection with and without appropriate antibiotic prophylaxis in those colonized with MRSA. We reviewed 400 consecutive orthopaedic trauma patient episodes. Preoperative MRSA screening results, operative procedures, prophylactic antibiotics and postoperative course were explored. In addition to these consecutive patients, the hospital MRSA database over the previous 5 years identified 27 MRSA colonized acute trauma patients requiring surgery. Of the 400 consecutive patient episodes, 395(98.7%) had MRSA screening performed on admission. However, in 236 (59.0%) cases, the results were not available before the surgery. Seven patient episodes (1.8%) had positive MRSA colonization. Analysis of 27 MRSA colonized patients revealed that 20(74%) patients did not have the screening results available before the surgery. Only 5(18.5%) received Teicoplanin and 22(81.4%) received cefuroxime for antibiotic prophylaxis before their surgery. Of those receiving cefuroxime, five (22.73%) patients developed postoperative MRSA surgical site infection (SSI) but none of those (0%) receiving Teicoplanin had MRSA SSI. The absolute risk reduction for SSI with Teicoplanin as antibiotic prophylaxis was 22.73% (CI=5.22%-40.24%) and NNT (Number Needed to Treat) was 5 (CI=2.5-19.2) CONCLUSION: Lack of available screening results before the surgery may lead to inadequate antibiotic prophylaxis increasing the risk of MRSA surgical site infection. Glycopeptide (e.g.Teicoplanin) prophylaxis should be considered when there is history of MRSA colonization or MRSA screening results are not available before the surgery. Copyright © 2017.

    Median sternotomy, the most common means of accessing the heart for cardiac procedures, is associated with higher risk of surgical site infections (SSIs). A limited number of studies reporting the impact of medication use prior to cardiac surgery on the subsequent risk of SSIs usually focused on antibacterial prophylaxis. The objective of the current study was to evaluate the effect of medications prescribed commonly to cardiac patients on the risk of incident SSIs. The study analyzed data on consecutive cardiac surgery patients undergoing median sternotomy at a McGill University teaching hospital between April 1, 2011 and October 31, 2013. Exposure of interest was use of medications for heart disease and cardiovascular conditions in the seven days prior to surgery and those for comorbid conditions. The main outcome was SSIs occurring within 90 d after surgery. Univariate and multivariate logistic regression (adjusted odds ratio [AOR]) was used to evaluate the effect. The cohort included 1,077 cardiac surgery patients, 79 of whom experienced SSIs within 90 d of surgery. The rates for sternal site infections and harvest site infections were 5.8 (95% confidence interval [CI]: 4.4-7.3) and 2.5 (95% CI: 1.4-3.7) per 100 procedures, respectively. The risk of SSI was increased with the pre-operative use of immunosuppressors/steroids (AOR 3.47, 95% CI: 1.27-9.52) and α-blockers (AOR 3.74, 95% CI: 1.21-1.47). Our findings support the effect of immunosuppressors/steroids on the risk of SSIs and add evidence to the previously reported association between the use of anti-hypertensive medications and subsequent development of infection/sepsis.

    The objectives of patient selection and counseling are ultimately to enhance successful outcomes. However, the definition for success is often narrowly defined in published literature (ability to complete surgery, complications, satisfaction) and fails to account for patient desires and expectations, temporal changes, natural history of underlying diseases, or independent validation. Factors associated with satisfaction and dissatisfaction are often surgery-specific, although correlation with pre-operative expectations, revisions, and complications are common with most procedures. The process of appropriate patient selection is determined by the integration of patient and surgeon factors, including psychological capacity to handle unsatisfactory results, baseline expectations, complexity of case, and surgeon volume and experience. Using this model, a high-risk scenario includes one in which a low-volume surgeon performs a complex case in a patient with limited psychological capacity and high expectations. In contrast, a high-volume surgeon performing a routine case in a male with low expectations and abundant psychiatric reserve is more likely to achieve a successful outcome. To further help identify patients who are at high risk for dissatisfaction, a previously published mnemonic is recommended: CURSED Patient (compulsive/obsessive, unrealistic, revision, surgeon shopping, entitled, denial, and psychiatric). Appropriate patient counseling includes setting appropriate expectations, reviewing the potential and anticipated risks of surgery, post-operative instruction to limit complications, and long-term follow-up. As thorough counseling is often a time-consuming endeavor, busy practices may elect to utilize various resources including educational materials, advanced practice providers, or group visits, among others. The consequences for poor patient selection and counseling may range from poor surgical outcomes and patient dissatisfaction to lawsuits, loss of

    MitraClip is an approved therapy for mitral regurgitation (MR); however, health care resource utilization pre- and post-MitraClip remains understudied. Patients with functional and degenerative MR at high surgical risk in the EVEREST II High-Risk Registry and REALISM Continued-Access Study were linked to Medicare data. Pre- and post-MitraClip all-cause death, stroke, myocardial infarction, heart failure (HF), and bleeding hospitalizations were identified. Inpatient costs, adjusted to 2010 US dollars, were calculated, and event rate ratios and cost ratios were estimated with multivariable modeling. Among 403 linked patients, the mean age was 80 years, 60% were male, mean baseline left ventricular ejection fraction was 49.6%, 83.3% were New York Heart Association class III/IV, 78.2% were MR grade 3+/4+, and 63.3% had functional MR. All-cause hospitalization decreased from 1,854 to 1,435/1,000 person-years (Pproviders seeking to reduce HF hospitalizations and associated Medicare costs may consider MitraClip among appropriate patients likely to survive 1 year.

    Retrospective case series of surgically treated adolescent patients with scoliosis. To assess the prevalence and independent risk factors for postoperative shoulder imbalance in surgically treated adolescent patients with idiopathic scoliosis. Despite recent reports that have identified risk factors for postoperative shoulder imbalance, the relative risks remain unclear. A retrospective review of 85 consecutive patients treated with thoracic fusion with a minimum 2-year follow-up (mean, 3.1 yr) was conducted to investigate the patient radiographical measurements and demographics. Shoulder height difference (SHD) was measured as the graded height difference of the soft tissue shadows. A SHD more than 2 cm indicated an unbalanced shoulder. Patient demographics and radiographical data were studied to determine risk factors for postoperative SHD. The potential risk factors included age, sex, Risser sign, Cobb angle, flexibility, and apical vertebral rotation (AVR) of the main curve, upper-instrumented vertebra level, SHD, and clavicle chest cage angle difference (CCAD). Univariate and multivariate logistic regression analyses were performed to determine the independent risk factors for postoperative shoulder imbalance. Of the 85 patients, 21 patients presented postoperative shoulder imbalance. The univariate analysis indicated age, Risser sign, Cobb angle of the main curve, AVR of the main curve, and CCAD as risk factors, but the multivariate logistic regression analysis showed that only AVR of the main curve and CCAD were independent risk factors for postoperative shoulder imbalance (AVR, P = 0.04, odds ratio (OR): 3.54; CCAD, P = 0.01, OR: 5.10). Postoperative shoulder imbalance was observed in 25% of the surgically treated adolescent patients. The CCAD and AVR of the main thoracic curve were independent risk factors for postoperative shoulder imbalance in surgically treated patients with adolescent idiopathic scoliosis. The significant correlation between CCAD and

    Widespread overuse and inappropriate use of antibiotics contribute to increasingly antibiotic-resistant pathogens and higher health care costs. It is not clear whether routine antibiotic prophylaxis can reduce the rate of surgical site infection (SSI) in low-risk patients undergoing orthopaedic surgery. We designed a simple scorecard to grade SSI risk factors and determined whether routine antibiotic prophylaxis affects SSI occurrence during open reduction and internal fixation (ORIF) orthopaedic surgeries in trauma patients at low risk of developing SSI. The SSI risk scorecard (possible total points ranged from 5 to 25) was designed to take into account a patient's general health status, the primary cause of fractures, surgical site tissue condition or wound class, types of devices implanted, and surgical duration. Patients with a low SSI risk score (≤8 points) who were undergoing clean ORIF surgery were divided into control (routine antibiotic treatment, cefuroxime) and evaluation (no antibiotic treatment) groups and followed up for 13-17 months after surgery. The infection rate was much higher in patients with high SSI risk scores (≥9 points) than in patients with low risk scores assigned to the control group (10.7% vs. 2.2%, Prisk score. Implementation of this scoring system could guide the rational use of perioperative antibiotics and ultimately reduce antibiotic resistance, health care costs, and adverse reactions to antibiotics.

    Carotid endarterectomy success in symptomatic or asymptomatic patients has been demonstrated in NASCET and ACAS studies. Although, some patients with carotid stenosis have frequently other pathologies which increase risk in endarterectomy or other surgeries like coronary bypass and aortic-iliac reconstruction. Other patients have lesions such as post surgical restenosis, fibromuscular dysplasia, radiation stenosis or tumoral disease, or stenotic lesions above jaw angle. The main objectives of this work are: to demonstrate, upon the results, that multidisciplinary management of 1 patient with symptomatic or not carotid critical stenosis. Let to select, with strict clinical criteria, those doing well with endovascular therapy. To evaluate implantation technique, peryoperatory morbidity and mortality and permeability time with implanted dispositive. In this study, the preliminary experience of the neurovascular group at the Clinica Cardiovascular Santa Maria in Medellin is presented, during an 18 months period of multidisciplinary management in 15 patients, 7 men and 8 women with critical carotid stenosis. 18 procedures were performed and 21 stents were implanted. The mean age was 66 years. All patients had 70% or greater stenotic lesions, and 93.3% were symptomatic. Twelve (80%) had contraindications to perform surgery. one asymptomatic patient (6.6%) was referred with procedure indications and two (13.3%) requested the stent implantation as their own election. the patient with fibromuscular dysplasia was treated with Wallstent (number 4) and the remaining patients were treated with Palmaz stent. technical success was 100%, 3 patients had pacemaker rhythm, one patient (6.6%) presented extra-pyramidal syndrome which responded to medical treatment in 24 hours. one patient developed right side hemiparesis with total recovery in 4 hours. One patient with a critical left carotid artery stenosis presented right side hemiparesis (3/5) and aphasia, nine months later paresis

      To compare anthropometric z-scores with incidence of post-operative complications for patients undergoing primary cleft lip or palate repair.   This was a retrospective observational analysis of patients from a surgical center in Assam, India, and includes a cohort from a single surgical mission completed before the opening of the center.   Patients included in the study underwent surgery during an Operation Smile mission before the opening of Operation Smile's Guwahati Comprehensive Cleft Care Center in Guwahati, India. The remaining cohort received treatment at the center. All patients received preoperative assessment and screening; surgery; and postoperative care, education, and follow-up.   Our sample size included 1941 patients and consisted of all patients with complete information in the database who returned for follow-up after receiving primary cleft lip repair or primary cleft palate repair between January 2011 and April 2013.   Preoperative anthropometric measurements.   Postoperative complications.   Anthropometric z-scores were not a significant predictor of adverse surgical outcomes in the group analyzed. Palate surgery had increased risk of complication versus lip repair, with an overall odds ratio of 5.66 (P < .001) for all patients aged 3 to 228 months.   Anthropometric z-scores were not correlated with increased risk of surgical complications, possibly because patients were well screened for malnutrition before surgery at this center. Primary palate repair is associated with an approximate fivefold increased risk of developing postoperative complication(s) compared with primary lip repair.

    The multicenter EPIC (FiberNet Embolic Protection System in Carotid Artery Stenting Trial) single-arm trial evaluated the 30-day outcomes of a new design concept for embolic protection during carotid artery stenting (CAS). Embolic protection filters available for use during CAS include fixed and over-the-wire systems that rely on embolic material capture within a "basket" structure. The FiberNet Embolic Protection System (EPS), which features a very low crossing profile, consists of a three-dimensional fiber-based filter distally mounted on a 0.014 inch guidewire with integrated aspiration during filter retrieval. The trial enrolled 237 patients from 26 centers. Demographics, clinical and lesion characteristics, as well as adverse events through a 30-day follow-up were recorded. The mean age of the patients was 74 years, 64% were male and 20% had symptomatic carotid artery disease. The combined major adverse event (MAE) rate at 30 days for all death, stroke, and myocardial infarction was 3.0%. There were three major strokes (two ischemic and one hemorrhagic) and two minor strokes (both ischemic) for a 2.1% 30-day stroke rate. The procedural technical success rate was 97.5% and macroscopic evidence of debris was reported in 90.9% of the procedures. The FiberNet EPS, used with commercially available stents, produced low stroke rates following CAS in high surgical risk patients presenting with carotid artery disease. The unique filter design including aspiration during retrieval may have contributed to the low 30-day stroke rate reported during CAS in patients considered at high risk for complications following carotid endarterectomy (CEA).

    To identify risk factors for failure of a therapeutic injection leading to operative management of both medial and lateral epicondylitis. A national database was used to query Medicare Standard Analytic Files from 2005-2012 for patients treated with therapeutic injections for medial or lateral epicondylitis using CPT codes for injections associated with corresponding ICD-9 diagnostic codes (726.31 and 726.32, respectively). Those who subsequently underwent surgical treatment following injection were identified. A multivariate binomial logistic regression analysis was utilized to evaluate patient-related risk factors for requiring surgery within 2 years after therapeutic injection. 1,837 patients received therapeutic injections for medial epicondylitis. 52 (2.8%) required ipsilateral surgery at a mean of 429 ± 28 days post-injection. Risk factors for requiring surgical intervention included age lateral epicondylitis. 201 (3.1%) required subsequent surgery at a mean of 383 ± 128 days' post-injection. Risk factors included age lateral epicondylitis is low (~3%). Risk factors for failing a therapeutic injection include age  30) for medial epicondylitis and age lateral epicondylitis. Patients with these identified risk factors presenting with medial or lateral epicondylitis should be cautioned that they carry a higher risk of subsequent surgical treatment. Therapeutic, III.

    The aim of this study was to describe our experience with percutaneous ultrasound-guided radiofrequency ablation of kidney tumors. From July 2002 to August 2005, 45 radiofrequency ablations (RFA) in 42 selected patients with kidney tumor were performed. The patients had either contraindications to surgery procedures or had a solitary kidney. The average tumor size was 37.5 mm (range, 18-59 mm) with the mean age of 68 years (range, 28-83 years). RFA were performed based on radiographic findings. Needle biopsy was made only twice. Monopolar Cool-tip Tyco or bipolar Celon Olympus radiofrequency devices were used. The procedure was performed under conscious sedation with local anesthesia. Treatment efficacy was assessed by computed tomography and by Doppler ultrasound. The absence of contrast enhancement on computed tomography was considered to be a successful treatment. The average follow up was 14 months (range, 3-36 months). In 42 tumors (93%), total absence of contrast enhancement was obtained after the initial RFA and in three tumors (7%) after the second ablation session. There were no complications following 41 procedures, including all ablations in small (<35 mm) renal masses. In four procedures, minor complications were observed. All patients are alive. There has been no need for chronic hemodialysis and, until now, we have not observed any local recurrences with the exception of one metastasis to an ipsilateral adrenal gland. RFA of kidney tumors is a promising alternative treatment which could be considered for patients who are not suitable for surgery. (author)

    We developed an artificial intelligence program from a large computerized database of hemodynamic and oxygen transport measurements together with prior studies defining survivors' values, outcome predictors, and a branched-chain decision tree. The artificial intelligence program was then tested on the data of 100 survivors and 100 nonsurvivors not used for the development of the program or other analyses. Using the predictor as a surrogate outcome measure, the therapy recommended by the program improved the predicted outcome 3.16% per therapeutic intervention while the actual therapy given increased outcome 1.86% in surviving patients; the artificial intelligence-recommended therapy improved outcome 7.9% in nonsurvivors, while the actual therapy given increased predicted outcome -0.29% in nonsurvivors (p < .05). There were fewer patients whose predicted outcome decreased after recommended treatment (14%) than after the actual therapy given (37%). Review of therapy recommended by the program did not reveal instances of inappropriate or potentially harmful recommendations.

    Iatrogenic flattening of lumbar lordosis in patients with adolescent idiopathic scoliosis (AIS) was a major downside of first generation instrumentation. Current instrumentation systems allow a three-dimensional scoliosis correction, but flattening of lumbar lordosis remains a significant problem which is associated with decreased health-related quality of life. This study sought to identify risk factors for loss of lumbar lordosis in patients who had surgical correction of AIS with the use of segmental instrumentation. Patients were included if they had surgical correction for AIS with segmental pedicle screw instrumentation Lenke type 1 or 2 and if they had a minimum follow-up of 24 months. Two groups were created, based on the average loss of lumbar lordosis. The two groups were then compared and multivariate analysis was performed to identify parameters that correlated to loss of lumbar lordosis. Four hundred and seventeen patients were analyzed for this study. The average loss of lumbar lordosis at 24 months follow-up was an increase of 10° lordosis for group 1 and a decrease of 15° for group 2. Risk factors for loss of lumbar lordosis included a high preoperative lumbar lordosis, surgical decrease of thoracic kyphosis, and the particular operating surgeon. The lowest instrumented vertebra or spinopelvic parameters were two of many parameters that did not seem to influence loss of lumbar lordosis. This study identified important risk factors for decrease of lumbar lordosis in patients who had surgical treatment for AIS with segmental pedicle screw instrumentation, including a high preoperative lumbar lordosis, surgical decrease of thoracic kyphosis, and factors attributable to a particular operating surgeon that were not quantified in this study.

    The purpose of this study was to evaluate the feasibility, safety and midterm outcome of elective implantation of the Carotid Wallstent (registered) in patients considered to be at high surgical risk. In a prospective study, 54 carotid artery stenoses in 51 patients were stented over a 24-month period. Three patients underwent bilateral carotid artery stenting. Institutional inclusion criteria for invasive treatment of carotid occlusive disease (carotid endarterectomy or carotid artery stenting) are patients presenting with a 70% or more symptomatic stenosis and those with an 80% or more asymptomatic stenosis having a life-expectancy of more than 1 year. All patients treated by carotid artery stenting were considered at high risk for carotid endarterectomy because of a hostile neck (17 patients-31.5%) or because of severe comorbidities (37 patients-68.5%). No cerebral protection device was used. Of the 54 lesions, 33 (61.1%) were symptomatic and 21 (38.8%) were asymptomatic. Follow-up was performed by physical examination and by duplex ultrasonography at 1 month, 6 months, 1 year and 2 years after the procedure. All 54 lesions could be stented successfully without periprocedural stroke. Advert events during follow-up (mean 13.9 ± 5.7 months) were non-stroke-related death in 6 patients (11.1%), minor stroke in 4 stented hemispheres(7.4%), transient ipsilateral facial pain in 1 patient (1.8%),infection of the stented surgical patch in 1 patient (1.8%) and asymptomatic in stent restenosis in 4 patients (7.4%). The percutaneous implantation of the Carotid Wallstent (registered) , even without cerebral protection device, appears to be a safe procedure with acceptable clinical and ultrasonographic follow-up results in patients at high surgical risk. But some late adverse events such as ipsilateral recurrence of non-disabling (minor) stroke or in stent restenosis still remain real challenging problems

    Previous research has shown that sicker patients are less satisfied with their healthcare, but specific effects of adverse health outcomes have not been investigated. The present study aimed to assess whether patients who experience adverse outcomes, in hospital or after discharge, differ in their evaluation of quality of care compared with patients without adverse outcomes. In hospital adverse outcomes were prospectively recorded by surgeons and surgical residents as part of routine care. Four weeks after discharge, patients were interviewed by telephone about the occurrence of post-discharge adverse outcomes, and their overall evaluation of quality of hospital care and specific suggestions for improvements in the healthcare provided. Of 2145 surgical patients admitted to the Leiden University Medical Center in 2003, 1876 (88%) agreed to be interviewed. Overall evaluation was less favourable by patients who experienced post-discharge adverse outcomes only (average 19% lower). These patients were also more often dissatisfied (OR 2.02, 95% CI 1.24 to 3.31) than patients without adverse outcomes, and they more often suggested that improvements were needed in medical care (OR 2.07, 1.45 to 2.95) and that patients were discharged too early (OR 3.26, 1.72 to 6.20). The effect of in hospital adverse outcomes alone was not statistically significant. Patients with both in hospital and post-discharge adverse outcomes also found the quality of care to be lower (on average 33% lower) than patients without adverse outcomes. Post-discharge adverse outcomes negatively influence patients' overall evaluation of quality of care and are perceived as being discharged too early, suggesting that patients need better information at discharge.

    There is dilemma as to whether patients infected with the Human Immunodeficiency Virus (HIV) requiring implant orthopaedic surgery are at an increased risk for post-operative surgical site infection (SSI). We conducted a systematic review to determine the effect of HIV on the risk of post-operative SSI and sought to determine if this risk is altered by antibiotic use beyond 24 hours. We searched electronic databases, manually searched citations from relevant articles, and reviewed conference proceedings. The risk of postoperative SSI was pooled using Mantel-Haenszel method. We identified 18 cohort studies with 16 mainly small studies, addressing the subject. The pooled risk ratio of infection in the HIV patients when compared to non-HIV patients was 1.8 (95% Confidence Interval [CI] 1.3-2.4), in studies in Africa this was 2.3 (95% CI 1.5-3.5). In a sensitivity analysis the risk ratio was reduced to 1.4 (95% CI 0.5-3.8). The risk ratio of infection in patients receiving prolonged antibiotics compared to patients receiving antibiotics for up to 24 hours was 0.7 (95% CI 0.1-4.2). The results may indicate an increased risk in HIV infected patients but these results are not robust and inconclusive after conducting the sensitivity analysis removing poor quality studies. There is need for larger good quality studies to provide conclusive evidence. To better develop surgical protocols, further studies should determine the effect of reduced CD4 counts, viral load suppression and prolonged antibiotics on the risk for infection.

    The California Technology Assessment Forum is dedicated to assessment and public reporting of syntheses of available data on medical technologies. In this assessment, transcatheter aortic valve replacement (TAVR) was evaluated for patients with severe aortic stenosis (AS) who are at high risk for complications. In this assessment, 5 criteria were used: Regulatory approval, sufficient scientific evidence to allow conclusions on effectiveness, evidence that the technology improves net health outcomes, evidence that the technology is as beneficial as established methods, and availability of the technology outside investigational settings. In this assessment, all 5 criteria were judged to have been met. The primary benefit of TAVR is the ability to treat AS in patients who would otherwise be ineligible for surgical aortic valve replacement. It may also be useful for patients at high surgical risk by potentially reducing periprocedural complications and avoiding the morbidity and recovery from undergoing heart surgery. Potential harms include the need for conversion to an open procedure, perioperative death, myocardial infarction, stroke, bleeding, valve embolization, aortic regurgitation, heart block that requires a permanent pacemaker, renal failure, pulmonary failure, and major vascular complications such as cardiac perforation or arterial dissection. Potential long-term harms include death, stroke, valve failure or clotting, and endocarditis. As highlighted at the February 2012 California Technology Assessment Forum meeting, the dispersion of this technology to new centers across the United States must proceed with careful thought given to training and proctoring multidisciplinary teams to become new centers of excellence. TAVR is a potentially lifesaving procedure that may improve quality of life for patients at high risk for surgical AVR. However, attention needs to be paid to appropriate patient selection, their preoperative evaluation, surgical techniques, and

    Purpose: To compare the outcome of patients with invasive breast cancer both with and without lobular carcinoma in situ (LCIS)-positive/close surgical margins after breast-conserving treatment. Methods and Materials: We retrospectively studied 2358 patients with T1-T2 invasive breast cancer treated with lumpectomy and radiation therapy from January 1980 to December 2009. Median age was 57 years (range, 24-91 years). There were 82 patients (3.5%) with positive/close LCIS margins (<0.2 cm) and 2232 patients (95.7%) with negative margins. A total of 1789 patients (76%) had negative lymph nodes. Patients who received neoadjuvant chemotherapy were excluded. A total of 1783 patients (76%) received adjuvant systemic therapy. Multivariable analysis (MVA) was performed using Cox's proportional hazards model. Results: The 5-year cumulative incidence of locoregional recurrence (LRR) was 3.2% (95% confidence interval [CI] 2.5%-4.1%) for the 2232 patients with LCIS-negative surgical margins (median follow-up 104 months) and 2.8% (95% CI 0.7%-10.8%) for the 82 patients with LCIS-positive/close surgical margins (median follow-up 90 months). This was not statistically significant (P=.5). On MVA, LCIS-positive margins after the final surgery were not associated with increased risk of LRR (hazard ratio [HR] 3.4, 95% CI 0.5-24.5, P=.2). Statistically significant prognostic variables on Cox's MVA for risk of LRR included systemic therapy (HR 0.5, 95% CI 0.33-0.75, P=.001), number of positive lymph nodes (HR 1.11, 95% CI 1.05-1.18, P=.001), menopausal status (HR 0.96, 95% CI 0.95-0.98, P=.001), and histopathologic grade (grade 3 vs grade 1/2) (HR 2.6, 95% CI 1.4-4.7, P=.003). Conclusion: Our results suggest that the presence of LCIS at the surgical margin after lumpectomy does not increase the risk of LRR or the final outcome. These findings suggest that re-excision or mastectomy in patients with LCIS-positive/close final surgical margins is unnecessary.

    Full Text Available Background. The STOP-BANG questionnaire has been used to identify surgical patients at risk for undiagnosed obstructive sleep apnea (OSA by classifying patients as low risk (LR if STOP-BANG score < 3 or high risk (HR if STOP-BANG score ≥ 3. Few studies have examined whether postoperative complications are increased in HR patients and none have been described in oncologic patients. Objective. This retrospective study examined if HR patients experience increased complications evidenced by an increased length of stay (LOS in the postanesthesia care unit (PACU. Methods. We retrospectively measured LOS and the frequency of oxygen desaturation (<93% in cancer patients who were given the STOP-BANG questionnaire prior to cystoscopy for urologic disease in an ambulatory surgery center. Results. The majority of patients in our study were men (77.7%, over the age of 50 (90.1%, and had BMI < 30 kg/m2 (88.4%. STOP-BANG results were obtained on 404 patients. Cumulative incidence of the time to discharge between HR and the LR groups was plotted. By 8 hours, LR patients showed a higher cumulative probability of being discharged early (80% versus 74%, P=0.008. Conclusions. Urologic oncology patients at HR for OSA based on the STOP-BANG questionnaire were less likely to be discharged early from the PACU compared to LR patients.

    Full Text Available Objectives: The aim of this study was to assess the exposure of patients to organic substances produced and identified in surgical smoke formed in the abdominal cavity during laparoscopic cholecystectomy. Material and Methods: Identification of these substances in surgical smoke was performed by the use of gas chromatography-mass spectrometry (GC-MS with selective ion monitoring (SIM. The selected biomarkers of exposure to surgical smoke included benzene, toluene, ethylbenzene and xylene. Their concentrations in the urine samples collected from each patient before and after the surgery were determined by SPME-GC/MS. Results: Qualitative analysis of the smoke produced during laparoscopic procedures revealed the presence of a wide variety of potentially toxic chemicals such as benzene, toluene, xylene, dioxins and other substances. The average concentrations of benzene and toluene in the urine of the patients who underwent laparoscopic cholecystectomy, in contrast to the other determined compounds, were significantly higher after the surgery than before it, which indicates that they were absorbed. Conclusions: The source of the compounds produced in the abdominal cavity during the surgery is tissue pyrolysis in the presence of carbon dioxide atmosphere. All patients undergoing laparoscopic procedures are at risk of absorbing and excreting smoke by-products. Exposure of the patient to emerging chemical compounds is usually a one-time and short-term incident, yet concentrations of benzene and toluene found in the urine were significantly higher after the surgery than before it.

    Advanced age is a strong predictor of high perioperative mortality in surgical patients and patients aged 75 years and older have an elevated surgical risk, much higher than that of younger patients. Progressive advances in surgical techniques now make it possible to treat high-risk surgical patients with minimally invasive procedures. Endovascular techniques have revolutionized the treatment of several vascular diseases, in particular carotid stenosis, aortic pathologies, and severely incapacitating intermittent claudication or critical limb ischemia. The main advantages of the endovascular approach are the low complication rate, high rate of technical success and a good clinical outcome. Biliary stenting has improved the clinical status of severely ill patients with bile duct stricture before major surgery, and represents a good palliative therapy in the case of malignant biliary obstruction.

    Differences in the risk factors for surgical site infection (SSI) following open heart surgery and coronary artery bypass graft surgery are not well described. To identify and compare risk factors for SSI following open heart surgery and coronary artery bypass graft surgery. SSI surveillance data on open heart surgery (CARD) and coronary artery bypass graft surgery (CBGB) submitted to the Japan Nosocomial Infection Surveillance (JANIS) system between 2008 and 2010 were analysed. Factors associated with SSI were analysed using univariate modelling analysis followed by multi-variate logistic regression analysis. Non-binary variables were analysed initially to determine the most appropriate category. The cumulative incidence rates of SSI for CARD and CBGB were 2.6% (151/5895) and 4.1% (160/3884), respectively. In both groups, the duration of the operation and a high American Society of Anesthesiologists' (ASA) score were significant in predicting SSI risk in the model. Wound class was independently associated with SSI in CARD but not in CBGB. Implants, multiple procedures and emergency operations predicted SSI in CARD, but none of these factors predicted SSI in CBGB. There was a remarkable difference in the prediction of risk for SSI between the two types of cardiac surgery. Risk stratification in CARD could be improved by incorporating variables currently available in the existing surveillance systems. Risk index stratification in CBGB could be enhanced by collecting additional variables, because only two of the current variables were found to be significant for the prediction of SSI.

    Because of its complex nature, surgical pathology practice is prone to error. In this report, we describe our methods for reducing error as much as possible during the pre-analytical and analytical phases. This was achieved by revising procedures, and by using computer technology and automation. Most mistakes are the result of human error in the identification and matching of patient and samples. To avoid faulty data interpretation, we employed a new comprehensive computer system that acquires all patient ID information directly from the hospital's database with a remote order entry; it also provides label and request forms via-Web where clinical information is required before sending the sample. Both patient and sample are identified directly and immediately at the site where the surgical procedures are performed. Barcode technology is used to input information at every step and automation is used for sample blocks and slides to avoid errors that occur when information is recorded or transferred by hand. Quality control checks occur at every step of the process to ensure that none of the steps are left to chance and that no phase is dependent on a single operator. The system also provides statistical analysis of errors so that new strategies can be implemented to avoid repetition. In addition, the staff receives frequent training on avoiding errors and new developments. The results have been shown promising results with a very low error rate (0.27%). None of these compromised patient health and all errors were detected before the release of the diagnosis report.

    Full Text Available Abstract Background Patients undergoing major elective or urgent surgery are at high risk of death or significant morbidity. Measures to reduce this morbidity and mortality include pre-operative optimisation and use of higher levels of dependency care after surgery. We propose a pragmatic multi-centre randomised controlled trial of level of dependency and pre-operative fluid therapy in high-risk surgical patients undergoing major elective surgery. Methods/Design A multi-centre randomised controlled trial with a 2 * 2 factorial design. The first randomisation is to pre-operative fluid therapy or standard regimen and the second randomisation is to routine intensive care versus high dependency care during the early post-operative period. We intend to recruit 204 patients undergoing major elective and urgent abdominal and thoraco-abdominal surgery who fulfil high-risk surgical criteria. The primary outcome for the comparison of level of care is cost-effectiveness at six months and for the comparison of fluid optimisation is the number of hospital days after surgery. Discussion We believe that the results of this study will be invaluable in determining the future care and clinical resource utilisation for this group of patients and thus will have a major impact on clinical practice.

    Prophylaxis against venous thromboembolism (VTE) is routinely administered during the hospital stay in at-risk surgical and medical patients. However, in high-risk groups, the risk of deep-vein thrombosis or pulmonary embolism may persist for several weeks after discharge. The standard duration of thromboprophylaxis (6-14 days) may not provide adequate protection against such events. This article reviews published data on the efficacy and safety profile of extended-duration thromboprophylaxis in patients at high risk for VTE, the potential cost-effectiveness of such treatment, and practical aspects of ensuring an effective transition from the inpatient to the outpatient setting. MEDLINE and the Cochrane Database of Systematic Reviews were searched through January 2009 for relevant English-language reports of clinical trials, abstracts, and case reports. The search terms included, but were not limited to, venous thromboembolism, pulmonary embolism, anticoagulation, thromboprophylaxis, prolonged duration, and extended duration. The reference lists of the identified articles were reviewed for additional relevant publications. Congress Web sites were also consulted. The principal criteria for inclusion of a study were that it have a prospective, randomized design and include a control group. Case series and retrospective analyses were excluded. Studies have found that extended-duration thromboprophylaxis (28-45 days) with low-molecular-weight heparins (LMWHs) can reduce the risk of VTE in high-risk patients. In separate meta-analyses, extended-duration thromboprophylaxis with LMWH was associated with significant reductions in the likelihood of symptomatic VTE compared with standard-duration thromboprophylaxis in patients undergoing major orthopedic surgery (odds ratio [OR] = 0.38; 95% CI, 0.24-0.61) or major abdominal or pelvic surgery (Peto OR = 0.22; 95% CI, 0.06-0.80). There was large heterogeneity in the reported rates of major and minor bleeding. The occurrence of

    An important factor in the pathophysiology of venous thromboembolism is blood stasis, thus, preoperative hospitalization length of stay may be contributory to risk. We assessed preoperative hospital length of stay as a risk factor for venous thromboembolism. We performed a retrospective review of patients who underwent colorectal operations using univariate and multivariable propensity score analyses. This study was conducted at a tertiary referral hospital. Data on patients was obtained from the American College of Surgeons National Surgical Quality Improvement Program 2005-2011 Participant Use Data Files. Short-term (30-day) postoperative venous thromboembolism was measured. Our analysis included 242,670 patients undergoing colorectal surgery (mean age, 60 years; 52.9% women); of these, 72,219 (29.9%) were hospitalized preoperatively. The overall rate of venous thromboembolism was 2.07% (1.4% deep vein thrombosis, 0.5% pulmonary embolism, and 0.2% both). On multivariable analysis, the most predictive independent risk factors for venous thromboembolism were return to the operating room (OR, 1.62 (95% CI, 1.44-1.81); p relationship between preoperative lengths of stay and risk of postoperative venous thromboembolism (p risk factor for venous thromboembolism and its associated increase in mortality after colorectal surgery, whereas laparoscopy is a strong protective variable. Further research into preoperative screening for highest-risk patients is indicated.

    Psychiatric patients are liable to stereotyping by healthcare providers. We explored attitudes toward caring for psychiatric patients among 13 nurses working in general hospitals in Ireland. Participants thought aloud in response to a simulated patient case and described a critical incident of a patient for whom they had cared. Two attitudinal orientations were identified that correspond to stereotypical depictions of risk and vulnerability. The nurses described psychosocial care strategies that were pragmatic rather than authentically person-centered, with particular associations between risk-oriented attitudes and directive nursing care. Nurses had expectations likely to impede relationship building and collaborative care. Implications arising include the need for improved knowledge about psychiatric conditions and for access to professional development in targeted therapeutic communication skills.

    The risk factors for surgical site infections in surgery should be measured and monitored from admission to 30 days after the surgical procedure, because 30% of Surgical Site Infection is detected when the patient was discharged. Calculate the Relative Risk of associated factors to surgical site infections in adult with elective surgery. Patients were classified according to the surgery contamination degree; patient with surgery clean was defined as no exposed and patient with clean-contaminated or contaminated surgery was defined exposed. Risk factors for infection were classified as: inherent to the patient, pre-operative, intra-operative and post-operative. Statistical analysis; we realized Student t or Mann-Whitney U, chi square for Relative Risk (RR) and multivariate analysis by Cox proportional hazards. Were monitored up to 30 days after surgery 403 patients (59.8% women), 35 (8.7%) developed surgical site infections. The factors associated in multivariate analysis were: smoking, RR of 3.21, underweight 3.4 hand washing unsuitable techniques 4.61, transfusion during the procedure 3.22, contaminated surgery 60, and intensive care stay 8 to 14 days 11.64, permanence of 1 to 3 days 2.4 and use of catheter 1 to 3 days 2.27. To avoid all risk factors is almost impossible; therefore close monitoring of elective surgery patients can prevent infectious complications.

    Full Text Available Surgical site infections (SSI are an important cause of peri-surgical morbidity with risks that vary extensively between patients and surgeries. Quantifying SSI risk would help identify candidates most likely to benefit from interventions to decrease the risk of SSI.We randomly divided all surgeries recorded in the National Surgical Quality Improvement Program from 2010 into a derivation and validation population. We used multivariate logistic regression to determine the independent association of patient and surgical covariates with the risk of any SSI (including superficial, deep, and organ space SSI within 30 days of surgery. To capture factors particular to specific surgeries, we developed a surgical risk score specific to all surgeries having a common first 3 numbers of their CPT code.Derivation (n = 181 894 and validation (n = 181 146 patients were similar for all demographics, past medical history, and surgical factors. Overall SSI risk was 3.9%. The SSI Risk Score (SSIRS found that risk increased with patient factors (smoking, increased body mass index, certain comorbidities (peripheral vascular disease, metastatic cancer, chronic steroid use, recent sepsis, and operative characteristics (surgical urgency; increased ASA class; longer operation duration; infected wounds; general anaesthesia; performance of more than one procedure; and CPT score. In the validation population, the SSIRS had good discrimination (c-statistic 0.800, 95% CI 0.795-0.805 and calibration.SSIRS can be calculated using patient and surgery information to estimate individual risk of SSI for a broad range of surgery types.

    Flow in the aortic vasculature may impact stroke risk in patients with left ventricular assist devices (LVAD) due to severely altered hemodynamics. Patient-specific 3D models of the aortic arch and great vessels were created with an LVAD outflow graft at 45, 60 and 90° from centerline of the ascending aorta, in order to understand the effect of surgical placement on hemodynamics and thrombotic risk. Intermittent aortic valve opening (once every five cardiac cycles) was simulated and the impact of this residual native output investigated for the potential to wash out stagnant flow in the aortic root region. Unsteady CFD simulations with patient-specific boundary conditions were performed. Particle tracking for 10 cardiac cycles was used to determine platelet residence times and shear stress histories. Thrombosis risk was assessed by a combination of Eulerian and Lagrangian metrics and a newly developed thrombogenic potential metric. Results show a strong influence of LVAD outflow graft angle on hemodynamics in the ascending aorta and consequently on stroke risk, with a highly positive impact of aortic valve opening, even at low frequencies. Optimization of LVAD implantation and management strategies based on patient-specific simulations to minimize stroke risk will be presented

    2010-09-01

    The prevalence of latex allergy is increasing in surgical patient populations. Avoidance of exposure to the allergen is essential to minimizing perioperative complications in patients suspected to be at risk. Natural rubber latex has historically been ubiquitous in medical devices containing rubber. In 1998, the Food and Drug Administration (FDA) began to require the labeling of medical devices made from natural rubber latex; since that time substantial progress has been made in identifying latex-free alternatives. However, the rubber stoppers commonly found in pharmaceutical vial closures are exempt from FDA labeling requirements. Examination of the clinical and basic science literature regarding pharmaceutical vial closures supports limiting the rubber stopper to a single needle puncture as a safer practice, with the caveat that no strategy exists for the complete elimination of risk as long as stoppers made from natural rubber latex are used in pharmaceutical vials intended for human use.

    Recently, transcatheter aortic valve replacement (TAVR) has become the procedure of choice in high surgical risk patients with aortic stenosis (AS). However, its value is still debated in operable AS cases. We performed this meta-analysis to compare the safety and efficacy of TAVR to surgical aortic valve replacement (SAVR) in low-to-moderate surgical risk patients with AS. A systematic search of five authentic databases retrieved 11 eligible studies (20,056 patients). Relevant Data were pooled as risk ratios (RRs) or standardized mean differences (SMD), with their 95% confidence interval, using Comprehensive Meta-Analysis and RevMan software for windows. At one-year of follow-up, the pooled effect-estimates showed no significant difference between TAVR and SAVR groups in terms of all-cause mortality (RR 1.02, 95% CI [0.83, 1.26], stroke (RR 0.83, 95%CI [0.56, 1.21]), myocardial infarction (RR 0.82, 95% CI [0.57, 1.19]), and length of hospital stay (SMD -0.04, 95% CI [-0.34, 0.26]). The incidence of major bleeding (RR 0.45, 95% CI [0.24, 0.86]) and acute kidney injury (RR 0.52, 95% CI [0.30, 0.88]) was significantly lower in the TAVR group, compared to the SAVR group. However, TAVR was associated with a higher risk of permanent pacemaker implantation (RR 2.57, 95% CI [1.36, 4.86]), vascular-access complications at 1 year (RR 1.99, 95%CI [1.04, 3.80]), and paravalvular aortic regurgitation at 30 days (RR 3.90, 95% CI [1.25, 12.12]), compared to SAVR. Due to the comparable mortality rates in SAVR and TAVR groups and the lower risk of life-threatening complications in the TAVR group, TAVR can be an acceptable alternative to SAVR in low-to-moderate risk patients with AS. However, larger trials with longer follow-up periods are required to compare the long-term outcomes of both techniques.

    Salivary contamination of surgical wounds in clean-contaminated head and neck surgery with free flap reconstruction remains a major cause of infection and leads to significant morbidity. This study investigates the correlation between intraoral flora and surgical site infections (SSIs) among high-risk head and neck cancer patients undergoing resection and free flap reconstruction. One hundred twenty-nine patients were identified as being at high risk for infective complications based on cancer stage, tumor size, comorbid factors, and extent of reconstruction. All patients had intraoral swab cultures before surgery. Patients with culture-confirmed SSI after surgery were chosen for analysis, using the κ index and its 95% confidence interval for concordance analysis. All patients received clindamycin and gentamicin for antibiotic prophylaxis for 5 days. Antibiotic susceptibility testing of all isolates was obtained and analyzed. Thirty-seven patients experienced SSI, or an infection rate of 28.3%, occurring at a mean of 9.3 postoperative days. The overall concordance between oral flora and SSI was fair to moderate (κ index of 0.25), but detailed analysis shows a higher concordance for known and opportunistic pathogens, such as Pseudomonas aeruginosa and Enterococcus faecalis, compared to typical oral commensals. Antibiotic susceptibility tests show rapid and significant increases in resistance to clindamycin, indicating a need for a more effective alternative. Predicting pathogens in SSI using preoperative oral swabs did not demonstrate a good concordance in general for patients undergoing clean-contaminated head and neck surgery, although concordance for certain pathogenic species seem to be higher than for typical intraoral commensals. The rapid development of resistance to clindamycin precludes its use as a prophylactic agent.

  2. Can the surgical checklist reduce the risk of wrong site surgery in orthopaedics? - can the checklist help? Supporting evidence from analysis of a national patient incident reporting system

    Full Text Available Abstract Background Surgical procedures are now very common, with estimates ranging from 4% of the general population having an operation per annum in economically-developing countries; this rising to 8% in economically-developed countries. Whilst these surgical procedures typically result in considerable improvements to health outcomes, it is increasingly appreciated that surgery is a high risk industry. Tools developed in the aviation industry are beginning to be used to minimise the risk of errors in surgery. One such tool is the World Health Organization's (WHO surgery checklist. The National Patient Safety Agency (NPSA manages the largest database of patient safety incidents (PSIs in the world, already having received over three million reports of episodes of care that could or did result in iatrogenic harm. The aim of this study was to estimate how many incidents of wrong site surgery in orthopaedics that have been reported to the NPSA could have been prevented by the WHO surgical checklist. Methods The National Reporting and Learning Service (NRLS database was searched between 1st January 2008- 31st December 2008 to identify all incidents classified as wrong site surgery in orthopaedics. These incidents were broken down into the different types of wrong site surgery. A Likert-scale from 1-5 was used to assess the preventability of these cases if the checklist was used. Results 133/316 (42% incidents satisfied the inclusion criteria. A large proportion of cases, 183/316 were misclassified. Furthermore, there were fewer cases of actual harm [9% (12/133] versus 'near-misses' [121/133 (91%]. Subsequent analysis revealed a smaller proportion of 'near-misses' being prevented by the checklist than the proportion of incidents that resulted in actual harm; 18/121 [14.9% (95% CI 8.5 - 21.2%] versus 10/12 [83.3% (95%CI 62.2 - 104.4%] respectively. Summatively, the checklist could have been prevented 28/133 [21.1% (95%CI 14.1 - 28.0%] patient safety

    Bilateral salpingo-oophorectomy (BSO) in carriers of BRCA1 and BRCA2 mutations is widely recommended as part of a risk-reduction strategy for ovarian or breast cancer due to an underlying genetic predisposition. BSO is also performed as a therapeutic intervention for patients with hormone-positive premenopausal breast cancer. BSO may be performed via a minimally invasive approach with the use of three to four 5 mm and/or 12 mm ports inserted through a skin incision. To further reduce the morbidity associated with the placement of multiple port sites and to improve cosmetic outcomes, single-port laparoscopy has been developed with a single access point from the umbilicus. The purpose of this study was to evaluate the surgical outcomes associated with reducing the risks of salpingo-oophorectomy performed in a single port, while comparing multiport laparoscopy in women with a high risk for ovarian cancer. Single-port laparoscopy-BSO is feasible and safe, with favorable surgical and cosmetic outcomes when compared to conventional laparoscopy.

    Full Text Available The assessment of nutritional intakes during hospitalization is crucial, as it is known that nutritional status tends to worsen during the hospital stay, and this can lead to the negative consequences of malnutrition. International guidelines recommend the use of parenteral nutrition (PN in hypophagic, non-surgical patients at nutritional risk, with contraindications to enteral nutrition. However, to date, there are no published data regarding either energy intake or objective measurements associated with it in this patient population. The aim of the present exploratory methodological study was to evaluate whether phase angle (PhA and handgrip strength normalized for skeletal muscle mass (HG/SMM are sensitive early markers of energy intake in hypophagic, non-surgical patients at nutritional risk, with contraindications to enteral nutrition. We evaluated 30 eligible patients, who were treated with personalized dietary modifications and supplemental PN for at least one week during hospitalization. In a liner regression model adjusted for age, gender, basal protein intake and the basal value of each variable, a trend toward improvement of PhA and preservation of HG/SMM was observed in patients satisfying the estimated calorie requirements (N = 20, while a significant deterioration of these parameters occurred in those who were not able to reach the target (N = 10. The mean adjusted difference and 95% CI were +1.4° (0.5–2.3 (p = 0.005 for PhA and +0.23 (0.20–0.43 (p = 0.033 for HG/SMM. A significant correlation between PhA and HG/SMM variations was also observed (r = 0.56 (95% CI, 0.23–0.77; p = 0.0023. PhA and HG/SMM were able to distinguish between hypophagic, non-surgical patients at nutritional risk who satisfied their estimated caloric requirements and those who did not after a one-week personalized nutritional support. Clinical studies are warranted, in order to verify these preliminary observations and to validate the role of Ph

    The relationship between patient satisfaction and surgical quality is unclear for US hospitals. Using national data, we examined if hospitals with high patient satisfaction have lower levels of performance on accepted measures of the quality and efficiency of surgical care. Federal policymakers have made patient satisfaction a core measure for the way hospitals are evaluated and paid through the value-based purchasing program. There is broad concern that performance on patient satisfaction may have little or even a negative correlation with the quality of surgical care, leading to potential trade-offs in efforts to improve patient experience with other surgical quality measures. We used the Hospital Consumer Assessment of Healthcare Providers and Systems survey data from 2010 and 2011 to assess performance on patient experience. We used national Medicare data on 6 common surgical procedures to calculate measures of surgical efficiency and quality: risk-adjusted length of stay, process score, risk-adjusted mortality rate, risk-adjusted readmission rate, and a composite z score across all 4 metrics. Multivariate models adjusting for hospital characteristics were used to assess the independent relationships between patient satisfaction and measures of surgical efficiency and quality. Of the 2953 US hospitals that perform one of these 6 procedures, the median patient satisfaction score was 69.5% (interquartile range, 63%-75.5%). Length of stay was shorter in hospitals with the highest levels of patient satisfaction (7.1 days vs 7.7 days, P patient satisfaction had the higher process of care performance (96.5 vs 95.5, P patient satisfaction also had a higher composite score for quality across all measures (P patient satisfaction provided more efficient care and were associated with higher surgical quality. Our findings suggest there need not be a trade-off between good quality of care for surgical patients and ensuring a positive patient experience.

    Esophageal resection in patients with esophageal cancer (EC) is still associated with high mortality and morbidity rates. We aimed to develop a simple preoperative risk score for the prediction of short-term and long-term outcomes for patients with EC treated by esophageal resection. In total, 498 patients suffering from esophageal carcinoma, who underwent esophageal resection, were included in this retrospective cohort study. Three preoperative esophagectomy risk (PER) groups were defined based on preoperative functional evaluation of different organ systems by validated tools (revised cardiac risk index, model for end-stage liver disease score, and pulmonary function test). Clinicopathological parameters, morbidity, and mortality as well as disease-free survival (DFS) and overall survival (OS) were correlated to the PER score. The PER score significantly predicted the short-term outcome of patients with EC who underwent esophageal resection. PER 2 and PER 3 patients had at least double the risk of morbidity and mortality compared to PER 1 patients. Furthermore, a higher PER score was associated with shorter DFS (P PER score was identified as an independent predictor of tumor recurrence (hazard ratio [HR] 2.1; P PER score allows preoperative objective allocation of patients with EC into different risk categories for morbidity, mortality, and long-term outcomes. Thus, multicenter studies are needed for independent validation of the PER score.

    To identify pre-operative risk factors for surgical delay of more than 2 days after admission in patients older than 65 years with a hip fracture. A prospective observational study was conducted on 180 hip fractures in patients older than 65 years of age admitted to our hospital from January 2015 to April 2016. The data recorded included, patient demographics, day of admission, pre-fracture comorbidities, mental state, level of mobility and physical function, type of fracture, antiaggregant and anticoagulant medication, pre-operative haemoglobin value, type of treatment, and surgical delay. The mean age of the patients was 83.7 years. The mean Charlson Index was 2.8. The pre-fracture baseline co-morbidities were equal or greater than 2 in 70% of cases. Mean timing of surgery was 3.1 days. At the time of admission, 122 (67.7%) patients were fit for surgery, of which 80 (44.4%) underwent surgery within 2 days. A Charlson index greater than 2, anticoagulant therapy, and admission on Thursday to Saturday, were independently associated with a surgical delay greater than 2 days. The rate of hip fracture patients undergoing surgery within 2 days is low. Risk factors associated to surgical delay are non-modifiable. However, their knowledge should allow the development of protocols that can reduce surgical delay in this group of patients. Copyright © 2017 SECOT. Publicado por Elsevier España, S.L.U.

    To clarify the clinical features and risk factors of cervicogenic headache (CEH; as diagnosed according to the International Classification of Headache Disorders-Third Edition beta) in patients with cervical spine disorders requiring surgery. CEH is caused by cervical spine disorders. The pathogenic mechanism of CEH is hypothesized to involve a convergence of the upper cervical afferents from the C1, C2, and C3 spinal nerves and the trigeminal afferents in the trigeminocervical nucleus of the upper cervical cord. According to this hypothesis, functional convergence of the upper cervical and trigeminal sensory pathways allows the bidirectional (afferent and efferent) referral of pain to the occipital, frontal, temporal, and/or orbital regions. Previous prospective studies have reported an 86-88% prevalence of headache in patients with cervical myelopathy or radiculopathy requiring anterior cervical surgery; however, these studies did not diagnose headache according to the International Classification of Headache Disorders criteria. Therefore, a better understanding of the prevalence rate, clinical features, risk factors, and treatment responsiveness of CEH in patients with cervical spine disorders requiring surgery is necessary. We performed a single hospital-based prospective cross-sectional study and enrolled 70 consecutive patients with cervical spine disorders such as cervical spondylotic myelopathy, ossification of the posterior longitudinal ligament, cervical spondylotic radiculopathy, and cervical spondylotic myeloradiculopathy who had been scheduled to undergo anterior cervical fusion or dorsal cervical laminoplasty between June 2014 and December 2015. Headache was diagnosed preoperatively according to the International Classification of Headache Disorders-Third Edition beta. The Japanese Orthopaedic Association Cervical Myelopathy Evaluation Questionnaire, Neck Disability Index, and a 0-100 mm visual analog scale (VAS) were used to evaluate clinical

    The PARTNER group recently published a comparison between the latest generation SAPIEN 3 transcatheter aortic valve implantation (TAVI) system (Edwards Lifesciences, Irvine, CA, USA) and surgical aortic valve replacement (SAVR) in intermediate-risk patients, apparently demonstrating superiority of the TAVI and suggesting that TAVI might be the preferred treatment method in this risk class of patients. Nonetheless, assessment of the non-randomized methodology used in this comparison reveals challenges that should be addressed in order to elucidate the validity of the results. The study by Thourani and colleagues showed several major methodological concerns: suboptimal methods in propensity score analysis with evident misspecification of the propensity scores (PS; no adjustment for the most significantly different covariates: left ventricular ejection fraction, moderate-severe mitral regurgitation and associated procedures); use of PS quintiles rather than matching; inference on not-adjusted Kaplan-Meier curves, although the authors correctly claimed for the need of balancing score adjusting for confounding factors in order to have unbiased estimates of the treatment effect; evidence of poor fit; lack of data on valve-related death.These methodological flaws invalidate direct comparison between treatments and cannot support authors' conclusions that TAVI with SAPIEN 3 in intermediate-risk patients is superior to surgery and might be the preferred treatment alternative to surgery. © The Author 2017.

    To investigate the value of Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity (POSSUM) and a modification of the POSSUM system (P-P0SSUM) scoring system in predicting the surgical operative risk of pancreaticoduodenectomy for periampullary tumors. POSSUM and P-POSSUM scoring systems were used to retrospectively evaluate the clinical data of 432 patients with periampullar tumors who underwent pancreaticoduodenectomy in the Department of Abdominal Surgery, Cancer Hospital, Chinese Academy of Medical Sciences from January 1985 to December 2010. The predictive occurrence of postoperative complications and mortality rate were calculated according to the formula. ROC curve analysis and different group of risk factors were used to determine the discrimination ability of the two score systems, and to determine their predictive efficacy by comparing the actual and predictive complications and mortality rates, using Hosmer-Lemeshow test to determine the goodness of fit of the two scoring systems. The average physiological score of the 432 patients was 16.1 ± 3.5, and the average surgical severity score was 19.6 ± 2.7. ROC curve analysis showed that the area under ROC curve for mortality predicted by POSSUM and P-POSSUM were 0.893 and 0.888, showing a non-significant difference (P > 0.05) between them. The area under ROC curve for operative complications predicted by POSSUM scoring system was 0.575. The POSSUM score system was most accurate for the prediction of complication rates of 20%-40%, showing the O/E value of 0.81. Compared with the POSSUM score system, P-POSSUM had better ability in the prediction of postoperative mortality, when the predicted value of mortality was greater than 15%, the predictive result was more accurate, and the O/E value was 1.00. POSSUM and P-POSSUM scoring system have good value in predicting the mortality of patients with periampullary tumors undergoing pancreaticoduodenectomy, but a poorer value of

    Fluid strategies may impact on patient outcomes in major elective surgery. We aimed to study the effectiveness and cost-effectiveness of pre-operative fluid loading in high-risk surgical patients undergoing major elective surgery. This was a pragmatic, non-blinded, multi-centre, randomised, controlled trial. We sought to recruit 128 consecutive high-risk surgical patients undergoing major abdominal surgery. The patients underwent pre-operative fluid loading with 25 ml/kg of Ringer's solution in the six hours before surgery. The control group had no pre-operative fluid loading. The primary outcome was the number of hospital days after surgery with cost-effectiveness as a secondary outcome. A total of 111 patients were recruited within the study time frame in agreement with the funder. The median pre-operative fluid loading volume was 1,875 ml (IQR 1,375 to 2,025) in the fluid group compared to 0 (IQR 0 to 0) in controls with days in hospital after surgery 12.2 (SD 11.5) days compared to 17.4 (SD 20.0) and an adjusted mean difference of 5.5 days (median 2.2 days; 95% CI -0.44 to 11.44; P = 0.07). There was a reduction in adverse events in the fluid intervention group (P = 0.048) and no increase in fluid based complications. The intervention was less costly and more effective (adjusted average cost saving: £2,047; adjusted average gain in benefit: 0.0431 quality adjusted life year (QALY)) and has a high probability of being cost-effective. Pre-operative intravenous fluid loading leads to a non-significant reduction in hospital length of stay after high-risk major surgery and is likely to be cost-effective. Confirmatory work is required to determine whether these effects are reproducible, and to confirm whether this simple intervention could allow more cost-effective delivery of care.

    Intermittent vital signs measurements are the current standard on hospital wards, typically recorded once every 8 hours. Early signs of deterioration may therefore be missed. Recent innovations have resulted in 'wearable' sensors, which may capture patient deterioration at an earlier stage. The objective of this study was to determine whether a wireless 'patch' sensor is able to reliably measure respiratory and heart rate continuously in high-risk surgical patients. The secondary objective was to explore the potential of the wireless sensor to serve as a safety monitor. In an observational methods comparisons study, patients were measured with both the wireless sensor and bedside routine standard for at least 24 hours. University teaching hospital, single centre. Twenty-five postoperative surgical patients admitted to a step-down unit. Primary outcome measures were limits of agreement and bias of heart rate and respiratory rate. Secondary outcome measures were sensor reliability, defined as time until first occurrence of data loss. 1568 hours of vital signs data were analysed. Bias and 95% limits of agreement for heart rate were -1.1 (-8.8 to 6.5) beats per minute. For respiration rate, bias was -2.3 breaths per minute with wide limits of agreement (-15.8 to 11.2 breaths per minute). Median filtering over a 15 min period improved limits of agreement of both respiration and heart rate. 63% of the measurements were performed without data loss greater than 2 min. Overall data loss was limited (6% of time). The wireless sensor is capable of accurately measuring heart rate, but accuracy for respiratory rate was outside acceptable limits. Remote monitoring has the potential to contribute to early recognition of physiological decline in high-risk patients. Future studies should focus on the ability to detect patient deterioration on low care environments and at home after discharge. © Article author(s) (or their employer(s) unless otherwise stated in the text of

    Patients with diabetes have a high risk of surgical site infection (SSI) after ankle surgery. The aim of the present study was to investigate the efficacy of vacuum-assisted closure (VAC) in the prevention of SSI after ankle surgery compared with the efficacy of standard moist wound care (SMWC). A retrospective study was performed of unstable ankle fractures for surgical fixation in patients with diabetes from January 2012 to December 2014. VAC and SMWC were used for surgical incision coverage. The primary outcome was the incidence of SSI, and the secondary outcomes were the length of hospital stay and crude hospital costs. The data from 76 patients were analyzed, with 22 (28.95%) in the VAC group and 54 (71.05%) in the SMWC group. The incidence of SSI was 4.6% in the VAC group compared with 27.8% in the SMWC group (chi-square 5.076; p = .024), and the crude odds ratio for SSI in the VAC group was 0.124 (95% confidence interval 0.002 to 0.938). The length of hospital stay was lower in the VAC group than in the SMWC group (12.6 ± 2.7 days and 15.2 ± 3.5 days, respectively; t = 3.122, p = .003). The crude hospital costs were also lower in the VAC group than in the SMWC group (Chinese yuan 8643.2 ± 1195.3 and 9456.2 ± 1106.3, respectively; t = 2.839, p = .006). After logistic regression analysis, the adjusted odds ratio for the total SSI rate comparing VAC and SMWC was 0.324 (95% confidence interval 0.092 to 0.804; p = .021). Compared with SMWC, VAC can decrease the SSI rate after ankle surgery in patients with diabetes. This finding should be confirmed by prospective, randomized controlled clinical trials.

    With a limited number of access ports, minimally invasive surgery (MIS) often requires the complete removal of one tool and reinsertion of another. Modular or multifunctional tools can be used to avoid this step. In this study, soft computing techniques are used to optimally arrange a modular tool's functional tips, allowing surgeons to deliver treatment of improved quality in less time, decreasing overall cost. The investigators watched University Medical Center surgeons perform MIS procedures (e.g., cholecystectomy and Nissen fundoplication) and recorded the procedures to digital video. The video was then used to analyze the types of instruments used, the duration of each use, and the function of each instrument. These data were aggregated with fuzzy logic techniques using four membership functions to quantify the overall usefulness of each tool. This allowed subsequent optimization of the arrangement of functional tips within the modular tool to decrease overall time spent changing instruments during simulated surgical procedures based on the video recordings. Based on a prototype and a virtual model of a multifunction laparoscopic tool designed by the investigators that can interchange six different instrument tips through the tool's shaft, the range of tool change times is approximately 11-13 s. Using this figure, estimated time savings for the procedures analyzed ranged from 2.5 to over 32 min, and on average, total surgery time can be reduced by almost 17% by using the multifunction tool.

    from this controlled clinical trial demonstrate only trivial differences in overall healthcare costs and quality-adjusted life expectancy between the 2 strategies. If the CREST results can be replicated in clinical practice, these findings suggest that factors other than cost-effectiveness should be considered when deciding between treatment options for carotid artery stenosis in patients at standard risk for surgical complications.

    Surgeon engagement with social media is growing rapidly. Innovative applications in diverse fields of health care are increasingly available. The aim of this review is to explore the current and future applications of social media in surgical training. In addition, risks and barriers of social media engagement are analyzed, and recommendations for professional social media use amongst trainers and trainees are suggested. The published, peer-reviewed literature on social media in medicine, surgery and surgical training was reviewed. MESH terms including "social media", "education", "surgical training" and "web applications" were used. Different social media surgical applications are already widely available but limited in use in the trainee's curriculum. E-learning modalities, podcasts, live surgery platforms and microblogs are used for teaching purposes. Social media enables global research collaboratives and can play a role in patient recruitment for clinical trials. The growing importance of networking is emphasized by the increased use of LinkedIn, Facebook, Sermo and other networking platforms. Risks of social media use, such as lack of peer review and the lack of source confirmation, must be considered. Governing surgeon's and trainee's associations should consider adopting and sharing their guidelines for standards of social media use. Surgical training is changing rapidly and as such, social media presents tremendous opportunities for teaching, training, research and networking. Awareness must be raised on the risks of social media use. Copyright © 2018 Association of Program Directors in Surgery. All rights reserved.

    Rhabdomyolysis is a syndrome of injury of skeletal muscles associated with myoglobinuria, muscle weakness, electrolyte imbalance and often, acute kidney injury as severe complication. of this study is to detect the incidence of rhabdomyolysis in critically ill patients in the surgical intensive care unit (ICU), and to raise awareness of this medical condition and its treatment among the clinicians. A retrospective review of all surgical and trauma patients admitted to surgical ICU of the University Surgical Clinic "Mother Teresa" in Skopje, Macedonia, from January 1 st till December 31 st 2015 was performed. Patients medical records were screened for available serum creatine kinase (CK) with levels > 200 U/l, presence of myoglobin in the serum in levels > 80 ng/ml, or if they had a clinical diagnosis of rhabdomyolysis by an attending doctor. Descriptive statistical methods were used to analyze the collected data. Out of totally 1084 patients hospitalized in the ICU, 93 were diagnosed with rhabdomyolysis during the course of one year. 82(88%) patients were trauma patients, while 11(12%) were surgical non trauma patients. 7(7.5%) patients diagnosed with rhabdomyolysis developed acute kidney injury (AKI) that required dialysis. Average values of serum myoglobin levels were 230 ng/ml, with highest values of > 5000 ng/ml. Patients who developed AKI had serum myoglobin levels above 2000 ng/ml. Average values of serum CK levels were 400 U/l, with highest value of 21600 U/l. Patients who developed AKI had serum CK levels above 3000 U/l. Regular monitoring and early detection of elevated serum CK and myoglobin levels in critically ill surgical and trauma patients is recommended in order to recognize and treat rhabdomyolysis in timely manner and thus prevent development of AKI.

    Essential communication between healthcare staff is considered one of the key requirements for both safety and quality care when patients are handed over from one clinical area to other. This is particularly important in environments such as the operating theatre and intensive care where mistakes can be devastating. Health care has learned from other high-risk organisations (HRO) such as aviation where the use of checklists and human factors awareness has virtually eliminated human error and mistakes. To our knowledge, little has been published around ways to improve pathology specimen handover following surgery, with pathology request forms often conveying the bare minimum of information to assist the laboratory staff. Furthermore, the request form might not warn staff about potential hazards. In this article, we provide a brief summary of the factors involved in human error and introduce a novel checklist that can be readily completed at the same time as the routine pathology request form. This additional measure enhances safety, can help to reduce processing and mislabelling errors and provides essential information in a structured way assisting both laboratory staff and pathologists when handling head and neck surgical specimens. © 2017 John Wiley & Sons A/S.

    2015-06-01

    Patient satisfaction is an increasing area of interest due to implications of pay for performance and public reporting of results. Although scores are adjusted for patient factors, little is known about the relationship between hospital structure, postoperative outcomes, and patient satisfaction with the hospital experience. Hospitals participating in the University HealthSystem Consortium database from 2011-2012 were included. Patients were restricted to those discharged by general surgeons to isolate surgical patients. Hospital data were paired with Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) results from the Hospital Compare website. Postoperative outcomes were dichotomized based on the median for all hospitals and stratified based on surgical volume. The primary outcome of interest was high on overall patient satisfaction, whereas other HCAHPS domains were assessed as secondary outcomes. Chi square and binary logistic regression analyses were performed to evaluate whether postoperative outcomes or surgical volume more significantly influenced high patient satisfaction. The study population consisted of 171 hospitals from the University HealthSystem Consortium database. High surgical volume was a more important predictor of overall patient satisfaction regardless of hospital complication (P patient satisfaction on the HCAHPS survey than postoperative outcomes, whereas volume was less predictive in other HCAHPS domains. Patients may require more specific questioning to identify high quality, safe hospitals. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available Background & Aims: Patient safety is one of the indicators of risk management in clinical governance system. Surgical care is one of the most sophisticated medical care in the hospitals. So it is not surprising that nearly half of the adverse events, 66% were related to surgery. Pre-flight aircraft Inspection model is starting point for designing surgical safety checklist that use for audit procedure. The aim of this study is to evaluate the effect of the use of surgical safety checklist on surgical patients mortality and complications. Materials and Methods: This is a prospective descriptive study. This study was conducted in 2012 in the North West of Iran. The population consisted of patients who had undergoing surgery in α university of medical science`s hospital which have surgical department. In this study, 1125 patients underwent surgery within 3 months were studied. Data collection tool was designed based on WHO model and Surgcical Care and Outcomes Assessment Program(SCOAP. Data analysis was performed using the SPSS-20 statistical software and logistic regression analysis was used to calculate P values for each comparison. Results: No significant differences between patients in the two periods (before and after There was. All complications rate reduced from 11 percent to 4 percent after the intervention by checklist (p<0.001. In the all hospitals mortality rate was decreased from 3.44% to 1.3% (p <0.003. Overall rate of surgical site infection and unplanned return to the operating room was reduced (p<0.001 and p<0.046. Conclusion: Many people every year due to lack of safety in hospitals, lose their lives. Despite the risks, such as leaving surgery sets in patient body and wrong surgery is due to lack of proper safety programs during surgery. By using safety checklist in all hospitals mortality rate and complications was reduced but this reduction was extremely in α3 hospital (from 5.2% to 1.48%.

    Science.gov (United States)

    Fournier, Matthew N; Hallock, Justin; Mihalko, William M

    2016-08-01

    Obesity is a problem that is increasing in prevalence in the United States and in other countries, and it is a common comorbidity in patients seeking total joint arthroplasty for degenerative musculoskeletal diseases. Obesity, as well as commonly associated comorbidities such as diabetes mellitus, cardiovascular disease, and those contributing to the diagnosis of metabolic syndrome, have been shown to have detrimental effects on total joint arthroplasty outcomes. Although there are effective surgical and nonsurgical interventions which can result in weight loss in these patients, concomitant benefit on arthroplasty outcomes is not clear. Preoperative optimization of surgical risk in obese total joint arthroplasty patients is an important point of intervention to improve arthroplasty outcomes. Copyright © 2016 Elsevier Inc.

    Published data suggests that wedge resection for stage I non-small cell lung cancer (NSCLC) is associated with improved overall survival compared to stereotactic body radiation therapy. We report CyberKnife outcomes for high-risk surgical patients with biopsy-proven stage I NSCLC. PET/CT imaging was completed for staging. Three-to-five gold fiducial markers were implanted in or near tumors to serve as targeting references. Gross tumor volumes (GTVs) were contoured using lung windows; the margins were expanded by 5 mm to establish the planning treatment volume (PTV). Treatment plans were designed using a mean of 156 pencil beams. Doses delivered to the PTV ranged from 42 to 60 Gy in three fractions. The 30 Gy isodose contour extended at least 1 cm from the GTV to eradicate microscopic disease. Treatments were delivered using the CyberKnife system with tumor tracking. Examination and PET/CT imaging occurred at 3 month follow-up intervals. Forty patients (median age 76) with a median maximum tumor diameter of 2.6 cm (range, 1.4–5.0 cm) and a mean post-bronchodilator percent predicted forced expiratory volume in 1 s (FEV1) of 57% (range, 21–111%) were treated. A median dose of 48 Gy was delivered to the PTV over 3–13 days (median, 7 days). The 30 Gy isodose contour extended a mean 1.9 cm from the GTV. At a median 44 months (range, 12–72 months) follow-up, the 3 year Kaplan–Meier locoregional control and overall survival estimates compare favorably with contemporary wedge resection outcomes at 91 and 75%, respectively. CyberKnife is an effective treatment approach for stage I NSCLC that is similar to wedge resection, eradicating tumors with 1–2 cm margins in order to preserve lung function. Prospective randomized trials comparing CyberKnife with wedge resection are necessary to confirm equivalence.

    To investigate the use of machine learning to empirically determine the risk of individual surgical procedures and to improve surgical models with this information. American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) data from 2005 to 2009 were used to train support vector machine (SVM) classifiers to learn the relationship between textual constructs in current procedural terminology (CPT) descriptions and mortality, morbidity, Clavien 4 complications, and surgical-site infections (SSI) within 30 days of surgery. The procedural risk scores produced by the SVM classifiers were validated on data from 2010 in univariate and multivariate analyses. The procedural risk scores produced by the SVM classifiers achieved moderate-to-high levels of discrimination in univariate analyses (area under receiver operating characteristic curve: 0.871 for mortality, 0.789 for morbidity, 0.791 for SSI, 0.845 for Clavien 4 complications). Addition of these scores also substantially improved multivariate models comprising patient factors and previously proposed correlates of procedural risk (net reclassification improvement and integrated discrimination improvement: 0.54 and 0.001 for mortality, 0.46 and 0.011 for morbidity, 0.68 and 0.022 for SSI, 0.44 and 0.001 for Clavien 4 complications; P risk for individual procedures. This information can be measured in an entirely data-driven manner and substantially improves multifactorial models to predict postoperative complications. Copyright © 2014 Elsevier Inc.

    Presence of comorbidity in surgical patients may be associated with adverse perioperative events and increased the risk of morbidity and mortality. This audit was conducted to determine the frequencies of comorbidities in elective surgical patients and the outcome of anesthesia in a Tertiary Hospital in Nigeria. Observational study of a cross-section of adult patients scheduled for elective surgery over a 6-month period. A standardized questionnaire was used to document patients' demographics, the presence of comorbidity and type, surgical diagnosis, anesthetic technique, intraoperative adverse events, and outcome of anesthesia. The questionnaire was administered pre- and post-operatively to determine the effects of the comorbidities on the outcome of anesthesia. One hundred and sixty-five adult patients aged between 18 and 84 years were studied. There were 89 (53.9%) females and 76 (46.1%) males. Forty-five (27.3%) have at least one comorbidity. Hypertension was the most common (48.8%) associated illness. Other comorbidities identified include anemia (17.8%), asthma (8.9%), diabetes mellitus (6.7%), chronic renal disease (6.7%), and others. The perioperative period was uneventful in majority of patients (80.6%) despite the presence of comorbidities. Intraoperative adverse events include hypotension, hypertension, shivering, and vomiting. No mortality was reported. Hypertension was the most common comorbidity in this cohort of patients. The presence of comorbidity did not significantly affect the outcome of anesthesia in elective surgical patients.

    2016-10-01

    The association of surgical duration with the risk of surgical site infection (SSI) has not been quantified in neurosurgery. We investigated the association of operative duration in neurosurgical procedures with the incidence of SSI. We performed a retrospective cohort study involving patients who underwent neurosurgical procedures from 2005 to 2012 and were registered in the American College of Surgeons National Quality Improvement Project registry. To control for confounding, we used multivariable regression models and propensity score conditioning. During the study period there were 94,744 patients who underwent a neurosurgical procedure and met the inclusion criteria. Of these patients, 4.1% developed a postoperative SSI within 30 days. Multivariable logistic regression showed an association between longer operative duration with higher incidence of SSI (odds ratio [OR], 1.18; 95% confidence interval [CI], 1.16-1.20). Compared with procedures of moderate duration (third quintile, 40th-60th percentile), patients undergoing the longest procedures (>80th percentile) had higher odds (OR, 2.07; 95% CI, 1.86-2.31) of developing SSI. The shortest procedures (operative duration was associated with increased incidence of SSI for neurosurgical procedures. These results can be used by neurosurgeons to inform operative management and to stratify patients with regard to SSI risk. Copyright © 2016 Elsevier Inc. All rights reserved.

    Second branchial cleft anomalies predispose to recurrent infections, and surgical resection is recommended as the treatment of choice. There is no clear consensus regarding the timing or surgical technique in the operative treatment of these anomalies. Our aim was to compare the effect of age and operative techniques to patient characteristics and treatment outcome. A retrospective study of pediatric patients treated for second branchial sinuses or fistulae during 1998-2012 at two departments in our academic tertiary care referral center. Comparison of patient characteristics, preoperative investigations, surgical techniques and postoperative sequelae. Our data is based on 68 patients, the largest series in the literature. One-fourth (24%) of patients had any infectious symptoms prior to operative treatment. Patient demographics, preoperative investigations, use of methylene blue, or tonsillectomy had no effect on the surgical outcome. There were no re-operations due to residual disease. Three complications were observed postoperatively. Our patient series of second branchial cleft sinuses/fistulae is the largest so far and enables analyses of patient characteristics and surgical outcomes more reliably than previously. Preoperative symptoms are infrequent and mild. There was no difference in clinical outcome between the observed departments. Performing ipsilateral tonsillectomy gave no outcome benefits. The operation may be delayed to an age of approximately three years when anesthesiological risks are and possible harms are best avoided. Considering postoperative pain and risk of postoperative hemorrhage a routine tonsillectomy should not be included to the operative treatment of second branchial cleft fistulae.

    Pugliese, Omar Talhouk; Solari, Juan Lombardi; Ferreres, Alberto R

    2014-07-01

    The notion that consent to surgery must be informed implies not only that information should be provided by the surgeon but also that the information should be understood by the patient in order to give a foundation to his or her decision to accept or refuse treatment and thus, achieve autonomy for the patient. Nonetheless, this seems to be an idyllic situation, since most patients do not fully understand the facts offered and thus the process of surgical informed consent, as well as the patient's autonomy, may be jeopardized. Informed consent does not always mean rational consent.

    2018-03-02

    This paper presents a conceptual framework which outlines the risk factors associated with surgical wound dehiscence (SWD) as identified in the literature. The purpose for the development of the conceptual framework was to derive an evidence-based, informed understanding of factors associated with SWD, in order to inform a programme of research on the aetiology and potential risk factors of SWD. Incorporated within the patient-centric conceptual framework are patient related comorbidities, intraoperative and postoperative risk factors related to SWD. These are categorised as either 'mechanical' or 'physiological mechanisms' posited to influence these relationships. The use of the conceptual model for assessment of patients has particular clinical relevance for identification of risk and the management of patients in the pre-, intra- and postoperative period.

    The aim of this study was to evaluate the cost-effectiveness of transcatheter aortic valve replacement (TAVR) compared with surgical aortic valve replacement (AVR) for patients with severe aortic stenosis and high surgical risk. TAVR is an alternative to AVR for patients with severe aortic stenosis and high surgical risk. We performed a formal economic analysis based on cost, quality of life, and survival data collected in the PARTNER A (Placement of Aortic Transcatheter Valves) trial in which patients with severe aortic stenosis and high surgical risk were randomized to TAVR or AVR. Cumulative 12-month costs (assessed from a U.S. societal perspective) and quality-adjusted life-years (QALYs) were compared separately for the transfemoral (TF) and transapical (TA) cohorts. Although 12-month costs and QALYs were similar for TAVR and AVR in the overall population, there were important differences when results were stratified by access site. In the TF cohort, total 12-month costs were slightly lower with TAVR and QALYs were slightly higher such that TF-TAVR was economically dominant compared with AVR in the base case and economically attractive (incremental cost-effectiveness ratio economically dominated by AVR in the base case and economically attractive in only 7.1% of replicates. In the PARTNER trial, TAVR was an economically attractive strategy compared with AVR for patients suitable for TF access. Future studies are necessary to determine whether improved experience and outcomes with TA-TAVR can improve its cost-effectiveness relative to AVR.

    Full Text Available Abstract Background Selective serotonin reuptake inhibitors (SSRI decrease platelet-function, which suggests that SSRI use may increase the risk of post-surgical bleeding. Few studies have investigated this potential association. Methods We conducted a population-based study of the risk of re-operation due to post-surgical bleeding within two weeks of primary surgery among Danish women with primary breast cancer. Patients were categorised according to their use of SSRI: never users, current users (SSRI prescription within 30 days of initial breast cancer surgery, and former users (SSRI prescription more than 30 days before initial breast cancer surgery. We calculated the risk of re-operation due to post-surgical bleeding within 14 days of initial surgery, and the relative risk (RR of re-operation comparing SSRI users with never users of SSRI adjusting for potential confounders. Results 389 of 14,464 women (2.7% were re-operated. 1592 (11% had a history of SSRI use. Risk of re-operation was 2.6% among never users, 7.0% among current SSRI users, and 2.7% among former users. Current users thus had an increased risk of re-operation due to post-operative bleeding (adjusted relative risk = 2.3; 95% confidence interval (CI = 1.4, 3.9 compared with never users. There was no increased risk of re-operation associated with former use of SSRI (RR = 0.93, 95% CI = 0.66, 1.3. Conclusions Current use of SSRI is associated with an increased risk of re-operation due to bleeding after surgery for breast cancer.

    Currently, many scholars are concerned about the treatment of postoperative infection; however, few have completed multivariate analyses to determine factors that contribute to the risk of infection. Therefore, we conducted a multivariate analysis of a retrospectively collected database to analyze the risk factors for acute surgical site infection following lumbar surgery, including fracture fixation, lumbar fusion, and minimally invasive lumbar surgery. We retrospectively reviewed data from patients who underwent lumbar surgery between 2014 and 2016, including lumbar fusion, internal fracture fixation, and minimally invasive surgery in our hospital's spinal surgery unit. Patient demographics, procedures, and wound infection rates were analyzed using descriptive statistics, and risk factors were analyzed using logistic regression analyses. Twenty-six patients (2.81%) experienced acute surgical site infection following lumbar surgery in our study. The patients' mean body mass index, smoking history, operative time, blood loss, draining time, and drainage volume in the acute surgical site infection group were significantly different from those in the non-acute surgical site infection group (p operative type in the acute surgical site infection group were significantly different than those in the non-acute surgical site infection group (p operative type, operative time, blood loss, and drainage time were independent predictors of acute surgical site infection following lumbar surgery. In order to reduce the risk of infection following lumbar surgery, patients should be evaluated for the risk factors noted above.

    Full Text Available Background. Endometriosis is nowadays probably the most frequent cause of infertility or subfertility and is revealed in approximately 30–40% of infertile women. The association between fertility and minimal or mild endometriosis remains unclear and controversial. Moderate and severe forms of the disease distort anatomical relations in the minor pelvis, resulting in infertility. The goals of endometriosis treatment are relief of pain symptoms, prevention of the disease progression and fertility improvement. Treatment of stages I and II endometriosis (according to the R-AFS classification may be expectative, medical or surgical. In severely forms of the disease (stage III and IV the method of choice is surgical treatment. Combined medical and surgical treatment is justified only in cases, in which the complete endometriotic tissue removal is not possible or recurrence of pain symptoms occur. Nowadays, laparoscopic surgical treatment is the golden standard being the diagnostic and therapeutic tool during the same procedure. The aim of this study was to evaluate the fertility rate after surgical treatment of different stages of endometriosis.Patients and methods. In prospectively designed study 100 infertile women were included. The only known cause of infertility was endometriosis. In group A there were 51 patients with stage I and II endometriosis, whereas in group B there were 49 patients with stage III and IV of the disease. Endometriosis was diagnosed and treated laparoscopically. Endometriotic implants were removed either with bipolar coagulation or CO2 laser vaporisation, whereas adhesions were sharp or blunt dissected, and endometriomas stripped out of ovaries. Pregnancy rates were calculated for both groups of patients, and statistically compared between the groups.Results. Mean age of patients was 29.25 (SD ± 4.08 years and did not significantly differ between the groups of patients (29.5 years in group A and 29 years in group B. In

    Parenteral nutrition may protect patients unable to eat from malnutrition almost indefinitely. If fat is not also given EFAD will occur. This outlines a prospective study of 28 surgical patients on total intravenous fat-free nutrition to determine the developmental course of EFAD and the response to therapy. Twenty-eight patients ranging from newborn to 66 years receiving parenteral nutrition without fat had regular determinations of the composition of total plasma fatty acids and the triene/tetraene ratio using gas liquid chromatography. Physical signs of EFAD were looked for also. Patients found to have evidence of EFAD were treated with 10% Intralipid. Topical safflower oil was used in three infants. Total plasma fatty acid composition was restudied following therapy. In general, infants on fat-free intravenous nutrition developed biochemical EFAD within two weeks, but dermatitis took longer to become evident. Older individuals took over four weeks to develop a diagnostic triene/tetraene ratio (greater than 0.4; range 0.4 to 3.75). Therapeutic correction of biochemical EFAD took 7 to 10 days but dermatitis took longer to correct. Cutaneous application of safflower oil alleviated the cutaneous manifestations but did not correct the triene/tetraene ratio of total plasma fatty acids. These studies indicate that surgical patients who are unable to eat for two to four weeks, depending upon age and expected fat stores, should receive fat as a part of their intravenous regimen.

    Full Text Available Current literature on risk factors for surgical site infection (SSI in dermatological surgery in the absence of antibiotic prophylaxis is limited. The aim of this study was to retrospectively evaluate patients presenting for dermatological surgery. A total of 1,977 procedures were reviewed. SSI was clinically suspected in 79 (4.0% patients and confirmed by culture in 38 (1.9%. Using the strictest definition of SSI (clinical symptoms with positive culture significantly higher risk of SSI was found for location on the ear (odds ratio (OR 6.03, 95% confidence interval (95% CI 2.12–17.15, larger defects (OR 1.08 per cm2 increase, 95% CI 1.03–1.14, closure with flaps (OR 6.35, 95% CI 1.33–30.28 and secondary intention (OR 3.01, 95% CI 1.11–8.13. These characteristics were also associated with higher risk of clinically suspected SSI regardless of culture results with slightly lower ORs. In conclusion, the risk of acquiring a SSI is increased in surgeries performed on the ear, in larger wounds and in defects closed with flaps or healed by secondary intention.

    Full Text Available ABSTRACT Objective The aim was to assess whether postoperative calorie and protein intakes increase the risk of infection and prolonged length of stay in a tertiary care university hospital in Southern Brazil. Methods This is a prospective cohort study approved by the hospital's Research Ethics Committee. The sample consisted of adult patients undergoing elective surgery. The exclusion criteria included patients who could not undergo nutritional assessment and those with a planned hospital stay of fewer than 72 hours. Nutritional status was assessed on admission and every seven days thereafter until hospital discharge or death. Demographic and clinical data, as well as information regarding independent and outcome variables, were collected from the patient's records. Food intake assessment was conducted by researchers six times a week. Calorie and protein intakes were considered adequate if equal to or greater than 75% of the prescribed amount, and length of stay was considered prolonged when above the average for specialty and type of surgery. Data was analyzed using Poisson regression. Results Of the 519 study patients, 16.2% had adequate nutritional therapy. Most of these patients were men with ischemic heart disease and acquired immunodeficiency syndrome. After adjusting for confounders, inadequate nutritional therapy increased risk of infection by 121.0% (RR=2.21; 95%CI=1.01-4.86 and risk of prolonged length of stay by 89.0% (RR=1.89; 95%CI=1.01-3.53. Conclusion Most patients did not have adequate nutritional therapy. Those with inadequate nutritional therapy had a higher risk of infection and longer length of stay.

    Postoperative nausea and vomiting (PONV) affect approximately 80% of surgical patients and is associated with increased length of hospital stay and systemic costs. Preoperative and postoperative pain, anxiety and depression are also commonly reported. Recent evidence regarding their safety and effectiveness has not been synthesised. The aim of this systematic review is to evaluate the efficacy and safety of herbal medications for the treatment and prevention of anxiety, depression, pain and PONV in patients undergoing laparoscopic, obstetrical/gynaecological and cardiovascular surgical procedures. The following electronic databases will be searched up to 1 October 2016 without language or publication status restrictions: CENTRAL, MEDLINE, EMBASE, CINAHL, Web of Science and LILACS. Randomised clinical trials enrolling adult surgical patients undergoing laparoscopic, obstetrical/gynaecological and cardiovascular surgeries and managed with herbal medication versus a control group (placebo, no intervention or active control) prophylactically or therapeutically will be considered eligible. Outcomes of interest will include the following: anxiety, depression, pain, nausea and vomiting. A team of reviewers will complete title and abstract screening and full-text screening for identified hits independently and in duplicate. Data extraction, risk of bias assessments and evaluation of the overall quality of evidence for each relevant outcome reported will be conducted independently and in duplicate using the Grading of Recommendations Assessment Development and Evaluation classification system. Dichotomous data will be summarised as risk ratios; continuous data will be summarised as standard average differences with 95% CIs. This is one of the first efforts to systematically summarise existing evidence evaluating the use of herbal medications in laparoscopic, obstetrical/gynaecological and cardiovascular surgical patients. The findings of this review will be disseminated

    Previous studies show a prolongation of activated partial thromboplastin time and prothrombin time in healthy volunteers after treatment with sugammadex. The authors investigated the effect of sugammadex on postsurgical bleeding and coagulation variables. This randomized, double-blind trial enrolled patients receiving thromboprophylaxis and undergoing hip or knee joint replacement or hip fracture surgery. Patients received sugammadex 4 mg/kg or usual care (neostigmine or spontaneous recovery) for reversal of rocuronium- or vecuronium-induced neuromuscular blockade. The Cochran-Mantel-Haenszel method, stratified by thromboprophylaxis and renal status, was used to estimate relative risk and 95% confidence interval (CI) of bleeding events with sugammadex versus usual care. Safety was further evaluated by prespecified endpoints and adverse event reporting. Of 1,198 patients randomized, 1,184 were treated (sugammadex n = 596, usual care n = 588). Bleeding events within 24 h (classified by an independent, blinded Adjudication Committee) were reported in 17 (2.9%) sugammadex and 24 (4.1%) usual care patients (relative risk [95% CI], 0.70 [0.38 to 1.29]). Compared with usual care, increases of 5.5% in activated partial thromboplastin time (P sugammadex occurred 10 min after administration and resolved within 60 min. There were no significant differences between sugammadex and usual care for other blood loss measures (transfusion, 24-h drain volume, drop in hemoglobin, and anemia), or risk of venous thromboembolism, and no cases of anaphylaxis. Sugammadex produced limited, transient (<1 h) increases in activated partial thromboplastin time and prothrombin time but was not associated with increased risk of bleeding versus usual care.

    Hospital inpatients are frequently hypokalaemic. Low plasma potassium levels may cause life threatening complications, such as cardiac arrhythmias. Potassium supplementation may be administered parenterally or enterally. Oral potassium supplements have been associated with oesophageal ulceration, strictures and gastritis. An alternative to potassium salt tablets or solution is dietary modification with potassium rich food stuffs, which has been proven to be a safe and effective method for potassium supplementation. The potassium content of one medium banana is equivalent to a 12 mmol potassium salt tablet. Potassium supplementation by dietary modification has been shown to be equally efficacious to oral potassium salt supplementation and is preferred by the majority of patients. Subsequently, it is our practice to replace potassium using dietary modification, particularly in surgical patients having undergone oesophagogastrectomy or in those with peptic ulcer disease.

    To report the use of a newly constructed, covered, retrievable, expandable nitinol stent with barbs to overcome the problem of stent migration associated with conventional covered prostatic expandable stents and to evaluate prospectively the technical feasibility and clinical effectiveness of the stents in patients with benign prostatic hyperplasia (BPH). A covered retrievable expandable nitinol stent with four barbs was placed with use of an 18-F stent delivery system in seven consecutive patients with symptomatic BPH who had high operative risks. Age range of patients was 62-83 years (mean 74 years). In cases in which the stent migrated, it was replaced with a stent with eight barbs. The stents were routinely removed 4 months after placement using a 21-F stent removal set. Stent placement was technically successful and well tolerated in six of the seven patients. The remaining patient needed a second stent placement after removal of the first stent. The stent with four barbs migrated into the urinary bladder in four patients (57%); three of these patients received a second stent with eight barbs with good results, and the fourth patient did not need further treatment because his symptoms improved. Routine removal of the stent 4 months after placement was performed in three of the seven patients with good results. Retrievable stents with eight barbs seem to overcome the problem of stent migration associated with conventional prostatic expandable stents. Preliminary results suggest that stents with barbs are both feasible and effective in patients with BPH. Copyright © 2011 SIR. Published by Elsevier Inc. All rights reserved.

  18. Acute limb ischemia in cancer patients: should we surgically intervene?

    Tsang, Julian S

    2012-02-01

    BACKGROUND: Cancer patients have an increased risk of venous thromboembolic events. Certain chemotherapeutic agents have also been associated with the development of thrombosis. Reported cases of acute arterial ischemic episodes in cancer patients are rare. METHODS: Patients who underwent surgery for acute limb ischemia associated with malignancy in a university teaching hospital over a 10-year period were identified. Patient demographics, cancer type, chemotherapy use, site of thromboembolism, treatment and outcome were recorded. RESULTS: Four hundred nineteen patients underwent surgical intervention for acute arterial ischemia, 16 of these patients (3.8%) had associated cancer. Commonest cancer sites were the urogenital tract (n = 5) and the lungs (n = 5). Eight patients (50%) had been recently diagnosed with cancer, and four (25%) of these cancers were incidental findings after presentation with acute limb ischemia. Four patients (25%) developed acute ischemia during chemotherapy. The superficial femoral artery was the most frequent site of occlusion (50%), followed by the brachial (18%) and popliteal (12%) arteries. All patients underwent thromboembolectomy, but two (12%) patients subsequently required a bypass procedure. Six patients (37%) had limb loss, and in-patient mortality was 12%. Histology revealed that all occlusions were due to thromboembolism, with no tumor cells identified. At follow-up, 44% of patients were found to be alive after 1 year. CONCLUSION: Cancer and chemotherapy can predispose patients to acute arterial ischemia. Unlike other reports that view this finding as a preterminal event most appropriately treated by palliative measures, in this series, early diagnosis and surgical intervention enabled limb salvage and patient survival.

    Leucoscintigraphy with Tc-99m-HMPAO is an important diagnostic modality for localizing of the site of infection. It has distinct advantages over gallium 67 and indium-111 labelled leukocytes, in terms of better image quality, less cell activation and the choice of using Technetium instead of In-111. This study was designed to set up the technique in AEMC, Multan Pakistan, to assess the practicality of using the procedure, and to see if the results offered additional clinical information that could affect patient management in our clinical environment. 27 patients were studied using the technique. There were 17 post-surgical patients, 4 post-partal patients and 6 patients who did no fit into the above categories. An accuracy of 81%, sensitivity of 75% and a specificity of 100 % were achieved. The spectrum of clinical presentation was broad and included post-operative infections, intra-abdominal haematoms, brain abscesses, localized peritonitis, sterile and infected intraperitoneal collections, infected pleural effusions and pyrexia of unknown origin. It was concluded that this technique is practicable in our conditions and gives important clinical information. (author)

    To assess the nutritional response of a group of critically ill patients, as well as the differences in the response to nutritional support between medical and surgical patients. One-year long retrospective study including critically ill patients on artificial nutrition for 7 days. Throughout the first week, three nutritional biochemical controls were done that included albumin, prealbumin, transferrin, cholesterol, and electrolytes. Other data gathered were: nutritional risk index, age, gender, weight, height, APACHE, delay of onset of nutritional support, access route, predicted and real caloric intake, medical or surgical patient, hospital stay, duration of the central venous catheter, urinary tube, and/or mechanical ventilation, incidence and density of incidence of nosocomial infections. Sixty-three patients were studied, 30 (47%) medical and 33 (53%) surgical/trauma patients, with a usage of EN higher among medical patients (16/30, 53% vs. 5/33, 15%), PN higher among surgical patients (25/33, 76%), and mixed nutrition similar in both groups (5 medical and 3 surgical patients) (p = 0.001). There were no differences between medical and surgical patients regarding: both predicted and real caloric and nitrogenous intake, APACHE, delay of onset of nutrition, phosphorus, magnesium or glucose levels, mortality and incidence of nosocomial infections. There were no differences either in hospital stay or use of mechanical ventilation, although these tended to be lower in surgical patients. The baseline biochemical parameters did not show differences between both groups, although they were worse among surgical patients. These patients presented during the study period steady albumin levels with improvement in the remaining parameters, whereas medical patients showed a decrease in albumin and transferrin levels, steady prealbumin levels, and slightly improvement in cholesterol levels. We have observed higher usage of PN among surgical patients, which showed worse

    Postoperative nausea and vomiting frequently complicate outpatient anesthesia and surgery. The duration of treatment for this complication must occasionally extend beyond discharge from the hospital. In this study, we evaluated the commonly used anti-emetic promethazine for its efficacy in the post-discharge period. Adult outpatient surgical patients who had excessive postoperative nausea and vomiting in the recovery room, or who were at risk for postoperative nausea and vomiting following discharge were given two promethazine suppositories (25 mg) for home use. All patients were contacted by our recovery room nurses on the first business day after their surgery and questioned as to their use of the suppositories and, if used, their efficacy. We found that 55 percent of patients given promethazine suppositories for home use had nausea and vomiting in the post-discharge period. Of the patients given promethazine, 89 percent used the suppositories. All of these patients reported improvement in their symptoms following use of the suppositories. None reported adverse effects from the promethazine suppositories. In conclusion, we found promethazine suppositories to be an inexpensive and efficacious treatment for nausea and vomiting in adult outpatient surgical patients following discharge from the hospital. Side-effects were minimal, and our patients voiced no complaints about this mode of therapy. We recommend this therapy for treatment of nausea and vomiting after hospital discharge following adult outpatient surgery. PMID:10527366

    Aortic valve stenosis (AVS) is the most frequent acquired valvular heart disease in western industrialized countries and its prevalence considerably increases with age. Once becoming symptomatic severe AVS has a very poor prognosis. Progressive and rapid symptom deterioration leads to an impairment of functional status and compromised healthrelated quality-of-life (HrQoL) simultaneously. Until recently, surgical aortic valve replacement (SAVR) has been the only effective treatment option for improving symptoms and prolonging survival. Transcatheter aortic valve replacement (TAVR) emerged as an alternative treatment modality for those patients with severe symptomatic AVS in whom the risk for SAVR is considered prohibitive or too high. TAVR has gained clinical acceptance with almost startling rapidity and has even quickly become the standard of care for the treatment of appropriately selected individuals with inoperable AVS during recent years. Typically, patients currently referred for and treated by TAVR are elderly with a concomitant variable spectrum of multiple comorbidities, disabilities and limited life expectancy. Beyond mortality and morbidity, the assessment of HrQoL is of paramount importance not only to guide patient-centered clinical decision-making but also to judge this new treatment modality. As per current evidence, TAVR significantly improves HrQoL in high-surgical risk patients with severe AVS with sustained effects up to two years when compared with optimal medical care and demonstrates comparable benefits relative to SAVR. Along with a provision of a detailed overview of the current literature regarding functional and HrQoL outcomes in patients undergoing TAVR, this review article addresses specific considerations of the HrQoL aspect in the elderly patient and finally outlines the implications of HrQoL outcomes for medico-economic deliberations.

    Gynecomastia refers to a benign enlargement of the male breast. This article describes the authors' method of using power-assisted liposuction and gland removal through a subareolar incision for thin patients. Power-assisted liposuction is performed for removal of fatty breast tissue in the chest area to allow skin retraction. The subareolar incision is used to remove glandular tissue from a male subject considered to be within a normal weight range but who has bilateral grade 1 or 2 gynecomastia. Gynecomastia correction was successfully performed for all the patients. The average volume of aspirated fat breast was 100-200 ml on each side. Each breast had 5-80 g of breast tissue removed. At the 3-month, 6-month, and 1-year follow-up assessments, all the treated patients were satisfied with their aesthetic results. Liposuction has the advantages of reducing the fat tissue where necessary to allow skin retraction and of reducing the traces left by surgery. The combination of surgical excision and power-assisted lipoplasty also is a valid choice for the treatment of thin patients.

    Mucormycosis as a consequence of trauma is a devastating complication; these infections are challenging to control, with a fatality rate approaching 96% in immunocompromised patients. We present a case where a proactive approach was successfully employed to treat mucormycosis following complex polytrauma. Aggressive repeated surgical debridement, in combination with appropriate antifungal therapy, proved successful in this instance. In our opinion, mucormycosis in trauma mandates an aggressive surgical approach. This prevents ascending dissemination of mucormycosis and certainly reduces the risk of patient mortality as a direct result. Anti-fungal therapy should be used secondarily as an adjunct together with surgical debridement, or as an alternative when surgical intervention is not feasible.

    To evaluate associations between prophylactic preoperative antibiotic choice and surgical site infection rates after hysterectomy. A retrospective cohort study was performed of patients in the Michigan Surgical Quality Collaborative undergoing hysterectomy from July 2012 to February 2015. The primary outcome was a composite outcome of any surgical site infection (superficial surgical site infections or combined deep organ space surgical site infections). Preoperative antibiotics were categorized based on the recommendations set forth by the American College of Obstetricians and Gynecologists and the Surgical Care Improvement Project. Patients receiving a recommended antibiotic regimen were categorized into those receiving β-lactam antibiotics and those receiving alternatives to β-lactam antibiotics. Patients receiving nonrecommended antibiotics were categorized into those receiving overtreatment (excluded from further analysis) and those receiving nonstandard antibiotics. Multivariable logistic regression models were developed to estimate the independent effect of antibiotic choice. Propensity score matching analysis was performed to validate the results. The study included 21,358 hysterectomies. The overall rate of any surgical site infection was 2.06% (n=441). Unadjusted rates of "any surgical site infection" were 1.8%, 3.1%, and 3.7% for β-lactam, β-lactam alternatives, and nonstandard groups, respectively. After adjusting for patient and operative factors within clusters of hospitals, compared with the β-lactam antibiotics (reference group), the risk of "any surgical site infection" was higher for the group receiving β-lactam alternatives (odds ratio [OR] 1.7, confidence interval [CI] 1.27-2.07) or the nonstandard antibiotics (OR 2.0, CI 1.31-3.1). Compared with women receiving β-lactam antibiotic regimens, there is a higher risk of surgical site infection after hysterectomy among those receiving a recommended β-lactam alternative or nonstandard regimen.

    Acute suppurative parotitis (ASP) is a severe infection seen particularly in elderly surgical patients. Factors that increase the risk of ASP include post-operative dehydration, debilitating conditions, and immunosuppressed states. Case report and literature review. An 82-year-old female patient was admitted because of paralytic ileus, dehydration, and poor oral hygiene, and was in distress. After two days of hospitalization, the patient developed a progressive painful swelling of her right parotid gland and fever up to 39.0°C. Computed tomography scanning showed an abscess in the parotid gland. Because of her progressive clinical deterioration, the patient underwent operative drainage of the abscess and removal of the necrotic material. Unfortunately, she suffered multiple organ dysfunction syndrome and died. Acute suppurative parotitis requires prompt aggressive treatment that nevertheless may fail.

    Image-defined risk factors (IDRFs) have been propounded for predicting the surgical risks associated with localized neuroblastoma (NB) since 2009. In 2011, a new guideline (NG) for assessing IDRFs was published. According to the NG, the situation in which "the tumor is only in contact with renal vessels," should be considered to be "IDRF-present." Previously, this situation was diagnosed as "IDRF absent." In this study, we evaluated the IDRFs in localized NB patients to clarify the predictive capability of IDRFs for surgical complications, as well as the usefulness of the NG. Materials and A total of 107 localized patients with NB were included in this study. The enhanced computed tomography and magnetic resonance images from the time of their diagnoses were evaluated by a single radiologist. We also analyzed the association of clinical factors, including the IDRFs (before and after applying the NG), with surgical complications. Of the 107 patients, 33 and 74 patients were diagnosed as IDRF-present (OP group), and IDRF-absent (ON group) before the NG, respectively. According to the NG, there were 76 and 31 patients who were classified as IDRF-present (NP group) and IDRF absent (NN group), respectively. Thus, 43 (40%) patients in the ON group were reassigned to the NP group after the NG. Surgical complications were observed in 17 of 82 patients who underwent surgical resection. Of the patients who underwent secondary operations, surgical complication rates were 55% in the OP group and 44% in the NP group. According to a univariate analysis, non-INSS 1, IDRFs before and after the NG and secondary operations were significantly associated with surgical complications. In a multivariate analysis, non-INSS 1 status and IDRFs after the NG were significantly associated with surgical complications. Georg Thieme Verlag KG Stuttgart · New York.

    Surgical site infection (SSI) complicates approximately 2% of surgeries in the Veterans Affairs (VA) hospitals. Surgical site infections are responsible for increased morbidity, length of hospital stay, cost, and mortality. Surgical site infection can be minimized by modifying risk factors. In this study, we identified risk factors and developed accurate predictive surgical specialty-specific SSI risk prediction models for the Veterans Health Administration (VHA) surgery population. In a retrospective observation study, surgical patients who underwent surgery from October 2013 to September 2016 from 136 VA hospitals were included. The Veteran Affairs Surgical Quality Improvement Program (VASQIP) database was used for the pre-operative demographic and clinical characteristics, intra-operative characteristics, and 30-day post-operative outcomes. The study population represents 11 surgical specialties: neurosurgery, urology, podiatry, otolaryngology, general, orthopedic, plastic, thoracic, vascular, cardiac coronary artery bypass graft (CABG), and cardiac valve/other surgery. Multivariable logistic regression models were developed for the 30-day post-operative SSIs. Among 354,528 surgical procedures, 6,538 (1.8%) had SSIs within 30 days. Surgical site infection rates varied among surgical specialty (0.7%-3.0%). Surgical site infection rates were higher in emergency procedures, procedures with long operative duration, greater complexity, and higher relative value units. Other factors associated with increased SSI risk were high level of American Society of Anesthesiologists (ASA) classification (level 4 and 5), dyspnea, open wound/infection, wound classification, ascites, bleeding disorder, chemotherapy, smoking, history of severe chronic obstructive pulmonary disease (COPD), radiotherapy, steroid use for chronic conditions, and weight loss. Each surgical specialty had a distinct combination of risk factors. Accurate SSI risk-predictive surgery specialty

    Cigarette smoking is a known risk factor for postoperative complications. Quitting or cutting down on cigarettes around the time of surgery may reduce these risks. This study aimed to determine the feasibility of using electronic nicotine delivery systems (ENDS) to help patients achieve this goal, regardless of their intent to attempt long-term abstinence. An open-label observational study was performed of cigarette smoking adults scheduled for elective surgery at Mayo Clinic Rochester and seen in the pre-operative evaluation clinic between December 2014 and June 2015. Subjects were given a supply of ENDS to use prior to and 2 weeks after surgery. They were encouraged to use them whenever they craved a cigarette. Daily use of ENDS was recorded, and patients were asked about smoking behavior and ENDS use at baseline, 14 days and 30 days. Of the 105 patients approached, 80 (76%) agreed to participate; five of these were later excluded. Among the 75, 67 (87%) tried ENDS during the study period. At 30-day follow-up, 34 (51%) who had used ENDS planned to continue using them. Average cigarette consumption decreased from 15.6 per person/d to 7.6 over the study period (P < .001). At 30 days, 11/67 (17%) reported abstinence from cigarettes. ENDS use is feasible in adult smokers scheduled for elective surgery and is associated with a reduction in perioperative cigarette consumption. These results support further exploration of ENDS as a means to help surgical patients reduce or eliminate their cigarette consumption around the time of surgery. Smoking in the perioperative period increases patients' risk for surgical complications and healing difficulties, but new strategies are needed to help patients quit or cut down during this stressful time. These pilot data suggest that ENDS use is feasible and well-accepted in surgical patients, and worthy of exploration as a harm reduction strategy in these patients. © The Author 2016.

    Full Text Available Moderate induced hypothermia has become standard of care for children with peripartum hypoxic ischaemic encephalopathy. However, children with congenital abnormalities and conditions requiring surgical intervention have been excluded from randomised controlled trials investigating this, in view of concerns regarding the potential side effects of cooling that can affect surgery. We report two cases of children, born with congenital conditions requiring surgery, who were successfully cooled and stabilised medically before undergoing surgery. Our first patient was diagnosed after birth with duodenal atresia after prolonged resuscitation, while the second had an antenatal diagnosis of left-sided congenital diaphragmatic hernia and suffered an episode of hypoxia at birth. They both met the criteria for cooling and after weighing the pros and cons, this was initiated. Both patients were medically stabilised and successfully underwent therapeutic hypothermia. Potential complications were investigated for and treated as required before they both underwent surgery successfully. We review the potential side effects of cooling, especially regarding coagulation defects. We conclude that newborns with conditions requiring surgery need not be excluded from therapeutic hypothermia if they might benefit from it.

    Full Text Available The aim of the paper was to evaluate the surgical outcome in patients with spontaneous supratentorial intracerebral hemorrhage (ICH after surgical intervention, in respect to the initial clinical conditions, age, sex, hemispheric side and anatomic localization of ICH. Thirty-eight surgically treated patients with spontaneous supratentorial intracerebral hemorrhage were included in the study. The surgical outcome was evaluated three months after the initial admission, according to the Glasgow Outcome Scale (GOS. The surgical treatment was successful in 14 patients (37%, whereas it was unsuccessful in 24 patients (63%. We have detected a significant negative correlation between the Glasgow Coma Scale (GCS scores on admission and the GOS scores after three months, suggesting worse neurological outcome in patients with initially lower GCS scores. The surgical outcome in patients with ICH was not affected by the sex, the hemispheric side and the anatomic localization of ICH, but the age of the patients was estimated as a significant factor for their functional outcome, with younger patients being more likely to be treated successfully. The surgical outcome is affected from the initial clinical state of the patients and their age. The treatment of ICH is still an unsolved clinical problem and the development of new surgical techniques with larger efficiency in the evacuation of the hematoma is necessary, thus making a minimal damage to the normal brain tissue, as well as decreasing the possibility of postoperative bleeding.

    Patient value (V) is enhanced when quality (Q) is increased and cost (C) is diminished (V = Q/C). However, calculating value has been inhibited by a lack of risk-adjusted cost data. The aim of this analysis was to measure patient value before and after implementation of quality improvement and cost reduction programs. Multidisciplinary efforts to improve patient value were initiated at a safety-net hospital in 2012. Quality improvement focused on adoption of multiple best practices, and minimizing practice variation was the strategy to control cost. University HealthSystem Consortium (UHC) risk-adjusted quality (patient mortality + safety + satisfaction + effectiveness) and cost (length of stay + direct cost) data were used to calculate patient value over 3 fiscal years. Normalized ranks in the UHC Quality and Accountability Scorecard were used in the value equation. For all hospital patients, quality scores improved from 50.3 to 66.5, with most of the change occurring in decreased mortality. Similar trends were observed for all surgery patients (42.6 to 48.4) and for general surgery patients (30.9 to 64.6). For all hospital patients, cost scores improved from 71.0 to 2.9. Similar changes were noted for all surgical (71.6 to 27.1) and general surgery (85.7 to 23.0) patients. Therefore, value increased more than 30-fold for all patients, 3-fold for all surgical patients, and almost 8-fold for general surgery patients. Multidisciplinary quality and cost efforts resulted in significant improvements in value for all hospitalized patients as well as general surgery patients. Mortality improved the most in general surgery patients, and satisfaction was highest among surgical patients. Copyright © 2016 American College of Surgeons. Published by Elsevier Inc.

    Medical surgical nurses may not have the time or resources to provide effective pre- and post-operative instructions for patients in today's healthcare system. And, making timely physical assessments following discharge from the hospital is not always straightforward. Therefore, the risk for readmission associated with post-surgical complications is a concern. At present, mobile healthcare technologies and patient care are precipitously evolving and may serve as a resource to enhance communication between the healthcare provider and patient. A mobile telephone text message (short message service [SMS]) intervention for abdominal surgical patients may foster effective education (communication) and timely self-reported physical assessment in the home environment hence preventing deleterious outcomes. The aim of this research proposal is to identify the feasibility of using a SMS intervention via smart phones to improve health outcomes via timely communication, reach large numbers of at-risk surgical patients and, establish and sustain uniform protocols in a cost-efficient manner.

    The number of surgical risks recalled by a patient after surgery can be used as a parameter for assessing how well the patient has understood the informed consent process. No study has investigated the usefulness of a self-developed mobile application in the traditional informed consent process in patients with a nasal bone fracture. This study aimed to investigate whether delivery of information, such as surgical risks, through a mobile application is more effective than delivery of information through only verbal means and a paper. This prospective, randomized study included 60 patients with a nasal bone fracture. The experimental group (n=30) received preoperative explanation with the traditional informed consent process in addition to a mobile application, while the control group (n=30) received preoperative explanation with only the traditional informed consent process. Four weeks after surgery, the number of recalled surgical risks was compared for analysis. The following six surgical risks were explained: pain, bleeding, nasal deformity, numbness, nasal obstruction, and nasal cartilage necrosis. The mean number of recalled surgical risks among all patients was 1.58±0.56. The most frequently recalled surgical risk was nasal deformity in both groups. The mean number of recalled surgical risks was 1.72±0.52 in the experimental group and 1.49±0.57 in the control group. There was a significant association between mobile application use and the mean number of recalled surgical risks ( p =0.047). Age, sex, and the level of education were not significantly associated with the mean number of recalled surgical risks. This study found that a mobile application could contribute to the efficient delivery of information during the informed consent process. With further improvement, it could be used in other plastic surgeries and other surgeries, and such an application can potentially be used for explaining risks as well as delivering other types of information.

    Haematocrit has been studied as an outcome predictor. The aim of this study was to evaluate the correlation between low haematocrit at surgical intensive care unit admission and high disease scoring system score and early outcomes. This retrospective study included 4398 patients admitted to the surgical intensive care unit between January 2006 and July 2013. Acute physiology and chronic health evaluation and simplified acute physiology score II values were calculated and all variables entered as parameters were evaluated independently. Patients were classified as haematocrit if they had a haematocrit < 30% at surgical intensive care unit admission. The correlation between admission haematocrit and outcome was evaluated by univariate analysis and linear regression. A total of 1126 (25.6%) patients had haematocrit. These patients had higher rates of major cardiac events (4% vs 1.9%, p < 0.001), acute renal failure (11.5% vs 4.7%, p < 0.001), and mortality during surgical intensive care unit stay (3% vs 0.8%, p < 0.001) and hospital stay (12% vs 5.9%, p < 0.001). A haematocrit level < 30% at surgical intensive care unit admission was frequent and appears to be a predictor for poorer outcome in critical surgical patients. Patients with haematocrit had longer surgical intensive care unit and hospital stay lengths, more postoperative complications, and higher surgical intensive care unit and hospital mortality rates.

    Stimulation to bronchial mucosa is one of the major risk factor of asthma attack. When patients receive surgical intervention and general anesthesia, they are always exposed to stimulation to bronchial mucosa. Prevention method of bronchial asthma attack during surgical intervention is not established yet. We investigated that clinical course of patients with bronchial asthma who received general anesthesia and surgical intervention. Seventy-six patients with bronchial asthma were received general anesthesia and surgical intervention from 1993 to 1998. Twenty-four patients were mild asthmatic patients, 39 were moderate asthmatic patients and 13 were severe asthmatic patients. Preoperative treatment for preventing asthma attack was as follows; Eight patients were given intravenous infusion of aminophylline before operation. Fifty-two patients were given intravenous infusion of aminophylline and hydrocortisone before operation. Three patients were given intravenous infusion of hydrocortisone for consecutive 3 days before operation. Thirteen patients were given no treatment for preventing asthma attack. One patient was suffered from asthma attack during operation. She was given no preventing treatment for asthma attack before operation. Three patients were suffered from asthma attack after operation. No wound dehiscence was observed in all patients. To prevent asthma attack during operation, intravenous infusion of steroid before operation is recommended, when patients with asthma receive general anesthesia and surgical intervention.

    The incidence of chronic post-surgical pain (CPSP) after various common operations is 10% to 50%. Identification of patients at risk of developing chronic pain, and the management and prevention of CPSP remains inadequate. The aim of this study was to develop an easily applicable risk index for the detection of high-risk patients that takes into account the multifactorial aetiology of CPSP. A comprehensive item pool was derived from a systematic literature search. Items that turned out significant in bivariate analyses were then analysed multivariately, using logistic regression analyses. The items that yielded significant predictors in the multivariate analyses were compiled into an index. The cut-off score for a high risk of developing CPSP with an optimal trade-off between sensitivity and specificity was identified. The data of 150 patients who underwent different types of surgery were included in the analyses. Six months after surgery, 43.3% of the patients reported CPSP. Five predictors multivariately contributed to the prediction of CPSP: capacity overload, preoperative pain in the operating field, other chronic preoperative pain, post-surgical acute pain and co-morbid stress symptoms. These results suggest that several easily assessable preoperative and perioperative patient characteristics can predict a patient's risk of developing CPSP. The risk index may help caregivers to tailor individual pain management and to assist high-risk patients with pain coping. © 2011 European Federation of International Association for the Study of Pain Chapters.

    2016-06-01

    Body piercing, a type of body modification that is practiced in many cultures, creates an unnatural tract through tissue that is then held open by artificial means. Today, professional body piercing is often performed in piercing establishments that are subject to dissimilar forms of regulation. The most frequently reported medical complication of body piercing and similar body modifications, such as dermal implantation, is infection. Patients with piercings who undergo surgery may have additional risks for infection, electrical burns, trauma, or airway obstruction. The published research literature on piercing prevalence, complications, regulations, education, and nursing care is outdated. The purpose of this article is to educate nurses on topics related to nursing care for patients with piercings and similar body modifications, including the history, prevalence, motivations for, and perceptions of body piercings as well as possible complications, devices used, locations, healing times, regulations, patient education, and other health concerns.

    The main treatment strategies for chronic pancreatitis in young patients include therapeutic endoscopic retrograde cholangio-pancreatography (ERCP) intervention and surgical intervention. Therapeutic ERCP intervention is performed much more extensively for its minimally invasive nature, but a part of patients are referred to surgery at last. Historical and follow-up data of 21 young patients with chronic pancreatitis undergoing duodenum-preserving total pancreatic head resection were analyzed to evaluate the outcomes of therapeutic ERCP intervention and surgical intervention in this study. The surgical complications of repeated therapeutic ERCP intervention and surgical intervention were 38% and 19% respectively. During the first therapeutic ERCP intervention to surgical intervention, 2 patients developed diabetes, 5 patients developed steatorrhea, and 5 patients developed pancreatic type B pain. During the follow-up of surgical intervention, 1 new case of diabetes occurred, 1 case of steatorrhea recovered, and 4 cases of pancreatic type B pain were completely relieved. In a part of young patients with chronic pancreatitis, surgical intervention was more effective than therapeutic ERCP intervention on delaying the progression of the disease and relieving the symptoms.

    Although medical treatment has advanced, surgical treatment is needed to control symptoms of Takayasu's arteritis (TA), such as angina, stroke, hypertension, or claudication. Endovascular or open surgical intervention is performed; however, there are few comparative studies on these methods. This meta-analysis and systematic review aimed to examine the outcome of surgical treatment of TA. A meta-analysis comparing outcomes of endovascular and open surgical intervention was performed using MEDLINE and Embase. This meta-analysis included only observational studies, and the evidence level was low to moderate. Data were pooled and analysed using a fixed or random effects model with the I 2 statistic. The included studies involved a total of 770 patients and 1363 lesions, with 389 patients treated endovascularly and 420 treated by surgical revascularization. Restenosis was more common with endovascular than open surgical intervention (odds ratio [OR] 5.18, 95% confidence interval [CI] 2.78-9.62; p open surgical intervention patients in the coronary artery, supra-aortic branches, and renal artery. In both the active and inactive stages, restenosis was more common in those treated endovascularly than in those treated by open surgery. However, stroke occurred less often with endovascular intervention than with open surgical intervention (OR 0.33, 95% CI 0.12-0.90; p = .003). Mortality and complications other than stroke and mortality did not differ between endovascular and open surgical intervention. This meta-analysis has shown a lower risk of restenosis with open surgical intervention than with endovascular intervention. Stroke was generally more common with open surgical intervention than with endovascular intervention. However, there were differences according to the location of the lesion, and the risk of stroke in open surgery is higher when the supra-aortic branches are involved rather than the renal arteries.

    Ankle fracture is a common injury and there is an increasingly greater emphasis on operative fixation. The purpose of the study was to determine the complication rate in this cohort of patients and, in doing so, determine risk factors which predispose to surgical site infection. A prospective cohort study was performed at a tertiary referral trauma center examining risk factors for surgical site infection in operatively treated ankle fractures. Univariate and multivariate analysis was performed. Female gender and advancing age were determined to be the risk factors in univariate analysis. Drain usage and peri-operative pyrexia were found to be significant for infection in multivariate analysis. This study allows surgeons to identify those at increased risk of infection and counsel them appropriately. It also allows for a high level of vigilance with regard to soft tissue handling intra-operatively in this higher risk group.

    Over the past decade, revelations of inappropriate financial relationships between surgeons and surgical device manufacturers have challenged the presumption that surgeons can collaborate with surgical device manufacturers without damaging public trust in the surgical profession. We explored postoperative Canadian patients' knowledge and opinions about financial relationships between surgeons and surgical device manufacturers. This complex issue was explored using qualitative methods. We conducted semistructured face-to-face interviews with postoperative patients in follow-up arthroplasty clinics at an academic hospital in Toronto, Canada. Interviews were audiotaped, transcribed and analyzed. Patient-derived concepts and themes were uncovered. We interviewed 33 patients. Five major themes emerged: 1) many patients are unaware of the existence of financial relationships between surgeons and surgical device manufacturers; 2) patients approve of financial relationships that support innovation and research but are opposed to relationships that involve financial incentives that benefit only the surgeon and the manufacturer; 3) patients do not support disclosure of financial relationships during the consent process as it may shift focus away from the more important risks; 4) patients support oversight at the professional level but reject the idea of government involvement in oversight; and 5) patients entrust their surgeons to make appropriate patient-centred choices. This qualitative study deepens our understanding of financial relationships between surgeons and industry. Patients support relationships with industry that provide potential benefit to current or future patients. They trust our ability to self-regulate. Disclosure combined with appropriate oversight will strengthen public trust in professional collaboration with industry.

    2009-10-01

    Surgical smoke is the gaseous by-product formed during surgical procedures. Most surgeons, operating theatre staff and administrators are unaware of its potential health risks. Surgical smoke is produced by various surgical instruments including those used in electrocautery, lasers, ultrasonic scalpels, high speed drills, burrs and saws. The potential risks include carbon monoxide toxicity to the patient undergoing a laparoscopic operation, pulmonary fibrosis induced by non-viable particles, and transmission of infectious diseases like human papilloma virus. Cytotoxicity and mutagenicity are other concerns. Minimisation of the production of surgical smoke and modification of any evacuation systems are possible solutions. In general, a surgical mask can provide more than 90% protection to exposure to surgical smoke; however, in most circumstances it cannot provide air-tight protection to the user. An at least N95 grade or equivalent respirator offers the best protection against surgical smoke, but whether such protection is necessary is currently unknown.

    Providing optimal care for critically ill and injured surgical patients will become more challenging with staff shortages for surgeons and intensivists. This white paper addresses the historical issues behind the present situation, the need for all intensivists to engage in dedicated critical care per the intensivist model, and the recognition that intensivists from all specialties can provide optimal care for the critically ill surgical patient, particularly with continuing involvement by the surgeon of record. The new acute care surgery training paradigm (including trauma, surgical critical care, and emergency general surgery) has been developed to increase interest in trauma and surgical critical care, but the number of interested trainees remains too few. Recommendations are made for broadening the multidisciplinary training and practice opportunities in surgical critical care for intensivists from all base specialties and for maintaining the intensivist model within acute care surgery practice. Support from academic and administrative leadership, as well as national organizations, will be needed.

    Full Text Available Background/Aim. Arthrosis of the hip is the most common cause of a hip joint disorders. The aim of this study was to present our experience in the application of a safe surgical dislocation of the hip in patients with minor morphological changes in the hip joint, which, through the mechanism of femoroacetabular impingement, cause damage to the acetabular labrum and adjacent cartilage as an early sign of the hip arthrosis. Methods. We have operated 51 patients with different morphological bone changes in the hip area and resultant soft tissue damage of the acetabular labrum and its adjacent cartilage. Surgical technique that we applied in this group of patients, was adapted to our needs and capabilities and it was minimaly modified compared to the original procedure. Results. The surgical technique presented in this paper, proved to be a good method of treatment of bone and soft tissue pathomorphological changes of the hip in patients with femoroacetabular impingement. We had no cases with avascular necrosis of the femoral head, and two patients had nonunion of the greater trochanter, 9 patients developed paraarticular ossification, without subjective symptoms, while 3 patients suffered from postoperative pain in the groin during more energetic physical activities. Conclusion. Utilization of our partly modified surgical technique of controlled and safe dislocation of the hip can solve all the bone and soft tissue problems in patients with femoroacetibular impingement to stop already developed osteoarthritis of the hip or to prevent mild form of it.

    To determine the risk factors, clinical characteristics, surgical management and outcome of pseudoaneurysm secondary to iatrogenic or traumatic vascular injury. This was a cross-sectional study being performed in department of cardiovascular and thoracic surgery skims soura during a 4-year period. We included all the patients referring to our center with primary diagnosis of pseudoaneurysm. The pseudoaneurysm was diagnosed with angiography and color Doppler sonography. The clinical and demographic characteristics were recorded and the risk factors were identified accordingly. Patients with small swelling (less than 5-cm) and without any complication were managed conservatively. They were followed for progression and development of complications in relation to swelling. Others underwent surgical repair and excision. The outcome of the patients was also recorded. Overall we included 20 patients with pseudoaneurysm. The mean age of the patients was 42.1±0.6 years. Among them there were 11 (55%) men and 9 (45%) women. Nine (45%) patients with end stage renal disease developed pseudoaneurysm after inadvertent femoral artery puncture for hemodialysis; two patients after interventional cardiology procedure; one after femoral embolectomy; one developed after fire arm splinter injury and one formed femoral artery related pseudoaneurysm after drainage of right inguinal abscess. The most common site of pseudoaneurysm was femoral artery followed by brachial artery. Overall surgical intervention was performed in 17 (85%) patients and 3 (15%) were managed conservatively. End stage renal disease is a major risk factor for pseudoaneurysm formation. Coagulopathy, either therapeutic or pathological is also an important risk factor. Patients with these risk factors need cannulation of venous structures for hemodialysis under ultrasound guide to prevent inadvertent arterial injury. Patients with end stage renal disease who sustain inadvertent arterial puncture during cannulation for

    Full Text Available In rural India most of the surgical patients become impoverished due to surgical treatment pushing several families below poverty line. We describe the various methods that we tried to help these patients pay for the surgical procedures without becoming impoverished. Some of them were successful and many of them were not so successful. The large turnover and innovative methods helped the mission hospitals to serve the poor and the marginalized. Some of these methods might not be relevant in areas other than Northeast India while many could be used in other areas.

    2015-01-01

    Full Text Available Background and Objectives: Surgical site infection (SSI is the most common nosocomial infection encountered in post operative surgical wards. The use of prophylactic antibiotic in clean elective surgical cases is still a subject of controversy to surgeons. The objective of the study is to identify the need for using prophylactic antibiotics in clean surgeries, prevalence of organisms in patients who are not given prophylactic antibiotics and to study whether the presence of risk factors increase the incidence of surgical site infection. Methodology: The comparative study consists of 100 cases admitted under two groups of 50 each: Group A was given prophylactic antibiotic and Group B didn’t receive any. All surgeries other than clean surgical cases were excluded from the study. Results: Out of 50 patients in group B who were not given prophylactic antibiotic, 2 patients had more than one risk factor for development of SSI and both of them developed SSI. Of the 50 patients who received prophylactic antibiotic, none developed SSI. The rate of infection in group A was nil and in Group B was 4%. Conclusion: Prophylactic antibiotics are not recommended for clean elective surgical cases as there is no statistically significant change in the infection rate seen in patients not receiving prophylactic antibiotic(P=0.4952. Meticulous surgical technique and correcting risk factors prior to surgery is a must for reducing incidence of SSI.

    Full Text Available BACKGROUND: Intellectually disabled patients have various comorbidities, but their risks of adverse surgical outcomes have not been examined. This study assesses pre-existing comorbidities, adjusted risks of postoperative major morbidities and mortality in intellectually disabled surgical patients. METHODS: A nationwide population-based study was conducted in patients who underwent inpatient major surgery in Taiwan between 2004 and 2007. Four controls for each patient were randomly selected from the National Health Insurance Research Database. Preoperative major comorbidities, postoperative major complications and 30-day in-hospital mortality were compared between patients with and without intellectual disability. Use of medical services also was analyzed. Adjusted odds ratios using multivariate logistic regression analyses with 95% confidence intervals were applied to verify intellectual disability's impact. RESULTS: Controls were compared with 3983 surgical patients with intellectual disability. Risks for postoperative major complications were increased in patients with intellectual disability, including acute renal failure (odds ratio 3.81, 95% confidence interval 2.28 to 6.37, pneumonia (odds ratio 2.01, 1.61 to 2.49, postoperative bleeding (odds ratio 1.35, 1.09 to 1.68 and septicemia (odds ratio 2.43, 1.85 to 3.21 without significant differences in overall mortality. Disability severity was positively correlated with postoperative septicemia risk. Medical service use was also significantly higher in surgical patients with intellectual disability. CONCLUSION: Intellectual disability significantly increases the risk of overall major complications after major surgery. Our findings show a need for integrated and revised protocols for postoperative management to improve care for intellectually disabled surgical patients.

    Full Text Available Objective: Metabolic acidosis after deep hypothermic circulatory arrest (DHCA for thoracic aortic operations is commonly managed with sodium bicarbonate (NaHCO 3 . The purpose of this study was to determine the relationships between total NaHCO 3 dose and the severity of metabolic acidosis, duration of mechanical ventilation, duration of vasoactive infusions, and Intensive Care Unit (ICU or hospital length of stay (LOS. Methods: In a single center, retrospective study, 87 consecutive elective thoracic aortic operations utilizing DHCA, were studied. Linear regression analysis was used to test for the relationships between the total NaHCO 3 dose administered through postoperative day 2, clinical variables, arterial blood gas values, and short-term clinical outcomes. Results: Seventy-five patients (86% received NaHCO 3 . Total NaHCO 3 dose averaged 136 ± 112 mEq (range: 0.0-535 mEq per patient. Total NaHCO 3 dose correlated with minimum pH (r = 0.41, P < 0.0001, minimum serum bicarbonate (r = −0.40, P < 0.001, maximum serum lactate (r = 0.46, P = 0.007, duration of metabolic acidosis (r = 0.33, P = 0.002, and maximum serum sodium concentrations (r = 0.29, P = 0.007. Postoperative hypernatremia was present in 67% of patients and peaked at 12 h following DHCA. Eight percent of patients had a serum sodium ≥ 150 mEq/L. Total NaHCO 3 dose did not correlate with anion gap, serum chloride, not the duration of mechanical ventilator support, vasoactive infusions, ICU or hospital LOS. Conclusion: Routine administration of NaHCO 3 was common for the management of metabolic acidosis after DHCA. Total dose of NaHCO 3 was a function of the severity and duration of metabolic acidosis. NaHCO 3 administration contributed to postoperative hypernatremia that was often severe. The total NaHCO 3 dose administered was unrelated to short-term clinical outcomes.

    The aim of this study was to assess the risk of headache in patients undergoing surgical treatment of intracranial aneurysms. The risk of the post-craniotomy headache has never been studied. Patients with intracranial aneurysm, who were consecutively admitted to the Hospital da Restauração, Brazil, from May 2009 to October 2010, were interviewed before they underwent surgical or non-surgical treatment of the aneurysms. The patients were followed for 4 months after intervention. The International Headache Society criteria for post-craniotomy headache were used after surgery and adapted for headache after embolization (maximum intensity of pain on the same side of the aneurysm). We also used the Headache Impact Test, the Hospital Anxiety and Depression Scale, and the Epworth Sleepiness Scale. Of 101 patients enrolled, 53 patients underwent craniotomy and 48 patients embolization. The surgery group was younger and had fewer women. The incidence of headache was 28/51 cases (54.9%) after surgery and 12/47 cases (25.5%) after embolization (relative risk = 2.15; 95% confidence interval [CI] 1.24-3.72). The incidence of persistent headache was not different between the 2 groups. The only risk factor for headache after the intervention was craniotomy (odds ratio = 2.6; 95% CI 1.1-6.7) and for persistent headache was anxiety prior to treatment (odds ratio = 8.5; 95% CI 1.7-42.3). The headache after treatment was not associated with the risk of anxiety or depression after the intervention. Patients who underwent craniotomy had an increased risk of headache after treatment of intracranial aneurysms. The incidence of persistent headache after 3 months was higher among patients who had anxiety before the intervention. © 2013 American Headache Society.

    Here, we present the clinical presentation and surgical outcomes of women with symptomatic urethral prolapse presenting to our institution over 20 years, and seek to provide treatment recommendations for management of symptomatic urethral prolapse and caruncle. A retrospective review of medical records from female patients who underwent surgery for symptomatic urethral prolapse from June 1995 to August 2015 was performed. Surgical technique consisted of a four-quadrant excisional approach for repair of urethral prolapse. A total of 26 patients were identified with a mean age of 38.8 years (range 3-81). The most common presentations were vaginal bleeding, hematuria, pain, and dysuria. All patients underwent surgical excision of urethral prolapse via a standard approach. Follow-up data was available in 24 patients. Six patients experienced temporary postoperative bleeding, and one patient required placement of a Foley catheter for tamponade. One patient experienced temporary postoperative urinary retention requiring Foley catheter placement. Three patients had visible recurrence of urethral prolapse, for which one later underwent re-excision. Surgical excision of urethral prolapse is a reasonable treatment option in patients who have tried conservative management without relief, as well as in those who present with severe symptoms. Possible complications following excision include postoperative bleeding and recurrence, and patients must be counseled accordingly. In this work, we propose a treatment algorithm for symptomatic urethral prolapse. © 2017 Wiley Periodicals, Inc.

    Age is considered as a risk factor in bariatric surgery. The observation was made on the basis of results from studies where patients underwent different type of surgery, but laparoscopic sleeve gastrectomy (LSG) was not among them. It is necessary to reevaluate the association of age with adverse events in the group of patients after LSG. To investigate the association of age with surgery-related adverse events in patients after LSG. Retrospective analysis of medical data was performed. The study involved 345 patients who underwent LSG in our institution between January 2013 and December 2014. The patients were subdivided by age into four groups according to quartiles. In 30-day follow-up adverse events were evaluated. We considered the presence of the following events as the endpoint of our study: death, medical events and surgical events. In general, we observed adverse events in 36 (10.4%) patients. The mortality rate in our study was 0.59%. Nineteen events were surgical and 18 medical. In 1 patient a surgical event was associated with a medical event. Bleeding was the most common surgical event and was observed in 17 (4.9%) cases. Age was not associated with surgical events (OR = 1.032, 95% CI: 0.991-1.075, p = 0.33) or medical events (OR = 0.997, 95% CI: 0.956-1.039, p = 0.89). The LSG is a safe bariatric procedure with low mortality. Bleeding is the most frequent surgical complication. Our findings suggest that age is not associated with increased risk of surgical or medical adverse events after LSG.

    To estimate the frequency of and risk factors for surgical-site infections (SSIs) in Bolivia, and to study the performance of the National Nosocomial Infections Surveillance (NNIS) System risk index in a developing country. A prospective study with patient follow-up until the 30th postoperative day. A general surgical ward of a public hospital in Santa Cruz, Bolivia. Patients admitted to the ward between July 1998 and June 1999 on whom surgical procedures were performed. Follow-up was complete for 91.5% of 376 surgical procedures. The overall SSI rate was 12%. Thirty-four (75.6%) of the 45 SSIs were culture positive. A logistic regression model retained an American Society of Anesthesiologists score of more than 1 (odds ratio [OR], 1.87), a not-clean wound class (OR, 2.28), a procedure duration of more than 1 hour (OR, 1.81), and drain (OR, 1.98) as independent risk factors for SSI. There was no significant association between the NNIS System risk index and SSI rates. However, a "local" risk index constructed with the above cutoff points showed a linear trend with SSI (P < .001) and a relative risk of 3.18 for risk class 3 versus a class of less than 3. SSIs cause considerable morbidity in Santa Cruz. Appropriate nosocomial infection surveillance and control should be introduced. The NNIS System risk index did not discriminate between patients at low and high risk for SSI in this hospital setting, but a risk score based on local cutoff points performed substantially better.

    Patients treated with antithrombotic therapy that require abdominal surgical procedures has progressively increased overtime. The management of antithrombotics during both the peri- and post- operative period is of crucial importance. The goal of this review is to present current data concerning the management of antiplatelets in patients with coronary artery disease and of anticoagulants in patients with atrial fibrillation who had to undergo abdominal surgical operations. For this purpose, incidence of major adverse cardiovascular events (MACE) and risk of antithrombotic use during surgical procedures, as well as the recommendations based on recent guidelines were reported. A thorough search of PubMed, Scopus and the Cochrane Databases was conducted to identify randomized controlled trials, observational studies, novel current reviews, and ESC and ACC/AHA guidelines on the subject. Antithrombotic use in daily clinical practice results to two different pathways: reduction of thromboembolic risk, but a simultaneous increase of bleeding risk. This may cause a therapeutic dilemma during the perioperative period. Nevertheless, careless cessation of antithrombotics can increase MACE and thromboembolic events, however, maintenance of antithrombotic therapy may increase bleeding complications. Studies and current guidelines can assist clinicians in making decisions for the treatment of patients that undergo abdominal surgical operations while on antithrombotic therapy. Aspirin should not be stopped perioperatively in the majority of surgical operations. Determining whether to discontinue the use of anticoagulants before surgery depends on the surgical procedure. In surgical operations with a low risk for bleeding, oral anticoagulants should not be discontinued. Bridging therapy should only be considered in patients with a high risk of thromboembolism. Finally, patients with an intermediate risk for thromboembolism, management should be individualized according to patient

    Without treatment, the life expectancy of patients with Marfan syndrome is reduced by the associated cardiovascular abnormalities. In this study, we reviewed our experience of the patients with Marfan syndrome who required multiple surgical interventions to identify the optimal treatment for these patients. Between January 1986 and December 2000, 44 patients with Marfan syndrome were operated on at Shizuoka City Hospital (SCH). Among them, 10 patients (22.7%) underwent multiple surgical interventions. There were 5 male and 5 female patients with a mean age of 40.6 +/- 16.1 years at the initial surgery. Only one patient was operated on at another hospital for his first, second, and third operations. His fourth operation was carried out at SCH. The remaining 9 patients underwent a total of 14 additional surgical procedures at SCH. Computed tomography (CT) scans were taken every 6 months postoperatively, and aortic diameter greater than 60 mm was considered as the indication for the additional surgery. There were no early death and one late death. The causes of additional surgery were enlargement of true aneurysm in 6, enlargement of residual dissection in 4, new dissection in 4, false aneurysm at the coronary anastomosis of Bentall procedure in 1. In 9 patients, both ascending and descending aorta were replaced. Among these 9 patients, only 3 patients underwent total arch replacement, and remaining 6 patients had their arch left in place with or without dissection. Our current strategy of the treatment of Marfan patients with acute type A dissection is total arch replacement with an elephant trunk at the initial emergent surgery.

Methods. The evaluation of vegetative homeostasis, reactivity of the vegetative nervous system by the data of variation pulsometry («REAN-POLY» RGPA-6/12, Taganrog in 60 patients with gonarthrosis at the age of 50-72 years and the disease duration — 9+1.5 years before and after surgical treatment: total tunnelization (Group I, tunnelization with osteotomy of leg bones for correction of limb biomechanical axis (Group II, treatment-and-diagnostic arthroscopy (Group III. Results. The reduction of the level of hypoxia tolerance and the decrease of the processes of general adaptation one month after surgery in Group I was registered in 40% of patients. As for patients of Group II, by the end of the period of fixation with the llizarov device — in 50%. As for those of Group III after arthroscopy — in 10% of patients. Among the patients whose 1С / 1С calculated parameter after surgical treatment was registered <1.0, its values were >10.0 before treatment in 70% of cases. At rest, marked vagotonia was registered with hypersympathicotonic reaction to orthotest, as well as with sharp decrease of the proportion of second-order slow waves while transition to standing position (VLF proportion <10.0%, thereby reflecting organism»s energy deficiency state. Conclusion. Preoperative examination. When VLF proportion after orthotest is registered <10.0%, such patients should be referred to risk group and prescribed in-depth examination. The index of centralization (1С dynamics for orthotest (1С test/1С rest is one of the criteria of functional recovery level for the particular patient: its increase points to the positive dynamics of restorative rehabilitative process, and the values <1.0 —to the negative one.

    AIM: To determine if surgical biliary bypass would provide improved quality of residual life and safe palliation in elderly patients with unresectable pancreatic head cancer. METHODS: Nineteen patients, 65 years of age or older, were managed with surgical biliary bypass (Group A). These patients were compared with 19 patients under 65 years of age who were managed with surgical biliary bypass (Group B). In addition, the results for group A were compared with those obtained from 17 patients, 65 years of age or older (Group C), who received percutaneous transhepatic biliary drainage to evaluate the quality of residual life. RESULTS: Five patients (26.0%) in Group A had complications, including one intraabdominal abscess, one pulmonary atelectasis, and three wound infections. One death (5.3%) occurred on postoperative day 3. With respect to morbidity, mortality, and postoperative hospitalization, no statistically significant difference was noted between Groups A and B. The number of readmissions and the rate of recurrent jaundice were lower in Group A than in Group C, to a statistically significant degree (P = 0.019, P = 0.029, respectively). The median hospital-free survival period and the median overall survival were also significantly longer in Group A (P = 0.001 and P < 0.001, respectively). CONCLUSION: Surgical palliation does not increase the morbidity or mortality rates, but it does increase the survival rate and improve the quality of life in elderly patients with unresectable pancreatic head cancer.

    Oral and maxillofacial surgery, which involves several sharp instruments and fixation materials, is consistently at a high risk for cross-contamination due to perforated gloves, but it is unclear how often such perforations occur. This study aimed to address this issue. The frequency of the perforation of surgical gloves (n=1436) in 150 oral and maxillofacial surgeries including orthognathic surgery (n=45) was assessed by the hydroinsufflation technique. Orthognathic surgery had the highest perforation rate in at least 1 glove in 1 operation (91.1%), followed by cleft lip and palate surgery (55.0%), excision of oral soft tumour (54.5%) and dental implantation (50.0%). The perforation rate in scrub nurses was 63.4%, followed by 44.4% in surgeons and first assistants, and 16.3% in second assistants. The odds ratio for the perforation rate in orthognathic surgery versus other surgeries was 16.0 (95% confidence interval: 5.3-48.0). The protection rate offered by double gloving in orthognathic surgery was 95.2%. These results suggest that, regardless of the surgical duration and blood loss in all fields of surgery, orthognathic surgery must be categorized in the highest risk group for glove perforation, following gynaecological and open lung surgery, due to the involvement of sharp objects.

    The aim of this study was to determine whether older postmenopausal women with a history of bilateral oophorectomy before natural menopause (surgical menopause) have a higher risk of nonvertebral postmenopausal fracture than women with natural menopause. We used 21 years of prospectively collected incident fracture data from the ongoing Study of Osteoporotic Fractures, a cohort study of community-dwelling women without previous bilateral hip fracture who were 65 years or older at enrollment, to determine the risk of hip, wrist, and any nonvertebral fracture. χ(2) and t tests were used to compare the two groups on important characteristics. Multivariable Cox proportional hazards regression models stratified by baseline oral estrogen use status were used to estimate the risk of fracture. Baseline characteristics differed significantly among the 6,616 women within the Study of Osteoporotic Fractures who underwent either surgical (1,157) or natural (5,459) menopause, including mean age at menopause (44.3 ± 7.4 vs 48.9 ± 4.9 y, P menopause, even among women who had never used oral estrogen (hip fracture: hazard ratio [HR], 0.87; 95% CI, 0.63-1.21; wrist fracture: HR, 1.10; 95% CI, 0.78-1.57; any nonvertebral fracture: HR, 1.11; 95% CI, 0.93-1.32). These data provide some reassurance that the long-term risk of nonvertebral fracture is not substantially increased for postmenopausal women who experienced premenopausal bilateral oophorectomy, compared with postmenopausal women with intact ovaries, even in the absence of postmenopausal estrogen therapy.

    Full Text Available Background. Appropriate critical care admissions are an important component of surgical care. However, there are few data describing postoperative critical care admission in resource-limited low- and middle-income countries. Objective. To describe the demographics, organ failures, organ support and outcomes of non-cardiac surgical patients admitted to critical care units in South Africa (SA. Methods. The SA Surgical Outcomes Study (SASOS was a 7-day national, multicentre, prospective, observational cohort study of all patients ≥16 years of age undergoing inpatient non-cardiac surgery between 19 and 26 May 2014 at 50 government-funded hospitals. All patients admitted to critical care units during this study were included for analysis. Results. Of the 3 927 SASOS patients, 255 (6.5% were admitted to critical care units; of these admissions, 144 (56.5% were planned, and 111 (43.5% unplanned. The incidence of confirmed or strongly suspected infection at the time of admission was 35.4%, with a significantly higher incidence in unplanned admissions (49.1 v. 24.8%, p<0.001. Unplanned admission cases were more frequently hypovolaemic, had septic shock, and required significantly more inotropic, ventilatory and renal support in the first 48 hours after admission. Overall mortality was 22.4%, with unplanned admissions having a significantly longer critical care length of stay and overall mortality (33.3 v. 13.9%, p<0.001. Conclusion. The outcome of patients admitted to public sector critical care units in SA is strongly associated with unplanned admissions. Adequate ‘high care-dependency units’ for postoperative care of elective surgical patients could potentially decrease the burden on critical care resources in SA by 23%.

    To understand how structural and process elements may affect the risk for surgical site infections (SSIs) in the ambulatory surgery center (ASC) environment, the researchers employed a tool known as socio-technical probabilistic risk assessment (ST-PRA). ST-PRA is particularly helpful for estimating risks in outcomes that are very rare, such as the risk of SSI in ASCs. Study objectives were to (1) identify the risk factors associated with SSIs resulting from procedures performed at ASCs and (2) design an intervention to mitigate the likelihood of SSIs for the most common risk factors that were identified by the ST-PRA for a particular surgical procedure. ST-PRA was used to study the SSI risk in the ASC setting. Both quantitative and qualitative data sources were utilized, and sensitivity analysis was performed to ensure the robustness of the results. The event entitled "fail to protect the patient effectively" accounted for 51.9% of SSIs in the ambulatory care setting. Critical components of this event included several failure risk points related to skin preparation, antibiotic administration, staff training, proper response to glove punctures during surgery, and adherence to surgical preparation rules related to the wearing of jewelry, watches, and artificial nails. Assuming a 75% reduction in noncompliance on any combination of 2 of these 5 components, the risk for an SSI decreased from 0.0044 to between 0.0027 and 0.0035. An intervention that targeted the 5 major components of the major risk point was proposed, and its implications were discussed.

    Summary Satisfaction of patients with their health care is gaining importance as a measure of hospital quality due to public reporting of these values and an increasing connection between hospital reimbursement and scores on the current tool to measure satisfaction, the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey. We found that high hospital and surgical volume and low rates of risk-adjusted mortality are associated with high patient satisfaction. However, other favorable patient outcomes are not consistently associated with positive satisfaction scores on HCAHPS. Contributors to patients' perceptions of their care are likely multifactorial and not related just to outcomes traditionally assessed by surgeons or hospitals. Moving in a direction of patient centered care, with a focus on increased understanding and involvement of patients in the care process, will likely strengthen the relationship between surgical outcomes and patient satisfaction.

    Rationale: Drug-resistant tuberculosis transmission in hospitals threatens staff and patient health. Surgical face masks used by patients with tuberculosis (TB) are believed to reduce transmission but have not been rigorously tested. Objectives: We sought to quantify the efficacy of surgical face masks when worn by patients with multidrug-resistant TB (MDR-TB). Methods: Over 3 months, 17 patients with pulmonary MDR-TB occupied an MDR-TB ward in South Africa and wore face masks on alternate days. Ward air was exhausted to two identical chambers, each housing 90 pathogen-free guinea pigs that breathed ward air either when patients wore surgical face masks (intervention group) or when patients did not wear masks (control group). Efficacy was based on differences in guinea pig infections in each chamber. Measurements and Main Results: Sixty-nine of 90 control guinea pigs (76.6%; 95% confidence interval [CI], 68–85%) became infected, compared with 36 of 90 intervention guinea pigs (40%; 95% CI, 31–51%), representing a 56% (95% CI, 33–70.5%) decreased risk of TB transmission when patients used masks. Conclusions: Surgical face masks on patients with MDR-TB significantly reduced transmission and offer an adjunct measure for reducing TB transmission from infectious patients. PMID:22323300

The data including clinical types and manifestations, surgical methods and outcomes were reviewed and analyzed. RESULTS: There were 11 male cases and 2 female cases who all had no ocular and systemic anomalies. The left eye was involved in 9 cases, the right eye was involved in 3 cases and 1 case involved in both eyes. Six cases were type Ⅰ,1 case was typeⅡand 6 cases were type Ⅲ. Eleven cases had abnormal head posture(AHP, 9 cases had the up- or down-shoot phenomenon. The surgical treatment was designed according to subtypes and clinical features which included medial rectus recession, lateral rectus recession, recession of both horizontal rectus muscles and lateral rectus recession combined with Y splitting. After surgery, horizontal deviation was less than ±10△ in all patients, and AHP disappeared in 4 cases and improved in 7 cases. The up- or down-shoot and global retraction disappeared in 5 cases and improved in 4 cases. Simultaneously, the restriction of ocular motility was improved in all patients. CONCLUSION: The clinical features of DRS are variant in different types. Detailed examination before surgery and reasonable surgical design are important in treatment of patients with DRS.

    High-resolution MRI can detect dual pathology (an extrahippocampal lesion plus hippocampal atrophy) in about 5-20% of patients with refractory partial epilepsy referred for surgical evaluation. We report the results of 41 surgical interventions in 38 adults (mean age 31 years, range 14-63 years) with dual pathology. Three patients had two operations. The mean postoperative follow-up was 37 months (range 12-180 months). The extrahippocampal lesions were cortical dysgenesis in 15, tumour in 10, contusion/infarct in eight and vascular malformation in five patients. The surgical approach aimed to remove what was considered to be the most epileptogenic lesion, and the 41 operations were classified into lesionectomy (removal of an extrahippocampal lesion); mesial temporal resection (removal of an atrophic hippocampus); and lesionectomy plus mesial temporal resection (removal of both the lesion and the atrophic hippocampus). Lesionectomy plus mesial temporal resection resulted in complete freedom from seizures in 11/15 (73%) patients, while only 2/10 (20%) patients who had mesial temporal resection alone and 2/16 (12.5%) who had a lesionectomy alone were seizure-free (P dual pathology removal of both the lesion and the atrophic hippocampus is the best surgical approach and should be considered whenever possible.

    Surgical site infection is a serious and significant complication after spinal surgery and is associated with high morbidity rates, high healthcare costs and poor patient outcomes. Accurate identification of risk factors is essential for developing strategies to prevent devastating infections. The purpose of this study was to identify independent risk factors for surgical site infection among posterior thoracic and/or lumbar spinal surgery in adult patients using a prospective multicenter surveillance research method. From July 2010 to June 2012, we performed a prospective surveillance study in adult patients who had developed surgical site infection after undergoing thoracic and/or lumbar posterior spinal surgery at 11 participating hospitals. Detailed preoperative and operative patient characteristics were prospectively recorded using a standardized data collection format. Surgical site infection was based on the definition established by the Centers for Disease Control and Prevention. A total of 2,736 consecutive adult patients were enrolled, of which 24 (0.9%) developed postoperative deep surgical site infection. Multivariate regression analysis indicated four independent risk factors. Preoperative steroid therapy (P = 0.001), spinal trauma (P = 0.048) and gender (male) (P = 0.02) were statistically significant independent patient-related risk factors, whereas an operating time ≥3 h (P operating time ≥3 h were independent risk factors for deep surgical site infection after thoracic and/or lumbar spinal surgery in adult patients. Identification of these risk factors can be used to develop protocols aimed at decreasing the risk of surgical site infection.

    Full Text Available Purpose: Myelomeningocele is one of the most common birth defects. It is associated with severe neurological deficiencies, and ocular changes, such as strabismus, are very common. The purpose of this study was to describe indications for strabismus surgery in patients with myelomeningocele and to evaluate the results achieved with surgical correction. Methods: We retrospectively reviewed records of all patients with myelomeningocele who underwent surgery for strabismus correction in a 5-year period in an institution for disabled children. Results: The main indications for strabismus surgery were esotropia and A-pattern anisotropia. Excellent surgical results were achieved in 60.9% of patients, satisfactory in 12.2%, and unsatisfactory in 26.9%. Conclusion: Patients with myelomeningocele and strabismus had a high incidence of esotropia and A-pattern anisotropia. Strabismus surgery in these patients had an elevated percentage of excellent and satisfactory results, not only for the ocular deviation, but also for improvement of head posture.

    A marked knowledge gap exists concerning the information needs of hepato-pancreato-biliary (HPB) surgical oncology patients. We investigated the comprehensive information needs of this patient population, including the type and amount of information desired, as well as the preferred method of receiving information. A questionnaire was administered to patients being treated surgically for cancers of the liver, pancreas, gallbladder, or bile ducts at Toronto General Hospital, part of the University Health Network, in Toronto, Canada. The questionnaire examined patients' information needs across six domains of information: medical, practical, physical, emotional, social, and spiritual. Among 36 respondents, the importance of information and amount of information desired differed significantly by domain (both p < 0.001). This group of patients rated information in the medical and physical domains as most important, though they also desired specific items of information from the emotional, practical, and social domains. Patients' overwhelming preference was to receive information via a one-on-one consultation with a healthcare provider. It is important for healthcare providers working with HPB surgical oncology patients to be comprehensive when providing information related to patients' cancer diagnosis, prognosis, associated symptoms, and side effects of treatment. Certain emotional, practical, and social issues (e.g., fears of cancer recurrence, drug coverage options, relationship changes) should be addressed as well. Face-to-face interactions should be the primary mode of delivering information to patients. Our findings are being used to guide the training of healthcare providers and the development of educational resources specific to HPB surgical oncology patients.

    The National Surgical Quality Improvement Program (NSQIP) of the American College of Surgeons provides risk-adjusted surgical outcome measures for participating hospitals that can be used for performance improvement of surgical mortality and morbidity. A surgical clinical nurse reviewer collects 135 clinical variables including preoperative risk factors, intraoperative variables, and 30-day postoperative mortality and morbidity outcomes for patients undergoing major surgical procedures. A report on mortality and complications is prepared twice a year. This article summarizes briefly the history of NSQIP and how its report on surgical outcomes can be used for performance improvement within a hospital system. In particular, it describes how to drive performance improvement with NSQIP data using the example of postoperative respiratory complications--a major factor of postoperative mortality. In addition, this article explains the benefit of a collaborative of several participating NSQIP hospitals and describes how to develop a "playbook" on the basis of an outcome improvement project.

    Antibiotic prophylaxis is a key component of the prevention of surgical site infection (SSI). Failure to manage antibiotic prophylaxis effectively may increase the risk of SSI. This study aimed to examine the effects of antibiotic prophylaxis on SSI risk. A retrospective cohort study was conducted among patients having general surgery between May 2012 and June 2015 at the University of Washington Medical Center. Peri-operative data extracted from hospital databases included patient and operation characteristics, intra-operative medication and fluid administration, and survival outcome. The effects of antibiotic prophylaxis and potential factors on SSI risk were estimated using multiple logistic regression and were expressed as risk ratios (RRs). A total of 4,078 patients were eligible for analysis. Of these, 180 had an SSI. Mortality rates within and after 30 days were 0.8% and 0.3%, respectively. Improper antibiotic redosing increased the risk of SSI (RR 4.61; 95% confidence interval [CI] 1.33-15.91). Other risk factors were in-patient status (RR 4.05; 95% CI 1.69-9.66), smoking (RR 1.63; 95% CI 1.03-2.55), emergency surgery (RR 1.97; 95% CI 1.26-3.08), colectomy (RR 3.31; 95% CI 1.19-9.23), pancreatectomy (RR 4.52; 95% CI 1.53-13.39), proctectomy (RR 5.02; 95% CI 1.72-14.67), small bowel surgery (RR 6.16; 95% CI 2.13-17.79), intra-operative blood transfusion >500 mL (RR 2.76; 95% CI 1.45-5.26), and multiple procedures (RR 1.40; 95% CI 1.01-1.95). These data demonstrate that failure to redose prophylactic antibiotic during long operations increases the risk of SSI. Strengthening a collaborative surgical quality improvement program may help to eradicate this risk.

    Surgical myocardial revascularization in patients with reduced left ventricular function has been a matter of debate for decades. Recently published 10-years extension follow-up of the STICH trial have conclusively demonstrated benefit of surgical myocardial revascularization in patients with significant coronary artery disease and low left ventricular ejection fraction. However, selection of patients for surgery remains challenging as well as decision to perform percutaneous rather than surgical revascularization in this class of patients. New evidence helped to clarify the role of preoperative patients' characteristics as risk factors for surgery and to identify those patients who may benefit the most from surgery. Focus of this review is to review epidemiology, aetiology and pathophysiology of coronary artery disease in patients with reduced left ventricular function, role of viability and results of observational and investigational studies on revascularization in patients with reduced left ventricular function with a particular emphasis on relative indication of coronary artery bypass grafting and percutaneous coronary intervention and the surgical implications of development of ischemic mitral regurgitation or ischemic left ventricular aneurysm.

    The incidence of surgical site infection (SSI) across surgical procedures, specialties, and conditions is reported to vary from 0.1% to 50%. Operative duration is often cited as an independent and potentially modifiable risk factor for SSI. The objective of this systematic review was to provide an in-depth understanding of the relation between operating time and SSI. This review included 81 prospective and retrospective studies. Along with study design, likelihood of SSI, mean operative times, time thresholds, effect measures, confidence intervals, and p values were extracted. Three meta-analyses were conducted, whereby odds ratios were pooled by hourly operative time thresholds, increments of increasing operative time, and surgical specialty. Pooled analyses demonstrated that the association between extended operative time and SSI typically remained statistically significant, with close to twice the likelihood of SSI observed across various time thresholds. The likelihood of SSI increased with increasing time increments; for example, a 13%, 17%, and 37% increased likelihood for every 15 min, 30 min, and 60 min of surgery, respectively. On average, across various procedures, the mean operative time was approximately 30 min longer in patients with SSIs compared with those patients without. Prolonged operative time can increase the risk of SSI. Given the importance of SSIs on patient outcomes and health care economics, hospitals should focus efforts to reduce operative time.

    Nutritional status of patients significantly affects the outcome of surgical treatment, whether it's about being obese or malnutrition with loss of muscle mass. Inadequate nutritional support in the perioperative period compromises surgical procedures even in patients who are adequately nourished. In this paper, particular attention was paid to malnourished patients, and their incidence in population hospitalized in surgical wards can be high up to 30%. Special emphasis was paid to the appropriateness of preoperative fasting and to the acceptance of new knowledge in this area of treatment. The aim of this working group was to make guidelines for perioperative nutritional support with different modalities of enteral nutrition. The development of these guidelines was attended by representatives of Croatian Medical Association: Croatian Society for Digestive Surgery, Croatian Society for Clinical Nutrition, Croatian Society of Surgery, Croatian Society for Endoscopic Surgery, Croatian Trauma Society and the Croatian Society of Anesthesiology and Intensive Care. The guidelines are designed as a set of questions that arise daily in clinical practice when preparing patients for surgery and after the surgical treatment, which relate to the assessment of nutritional status, perioperative nutritional support, duration of preoperative fasting period and the selection of food intake route. Assessment of nutritional status and the use of different modes of enteral nutrition should enter into standard protocols of diagnosis and treatment in the Croatian hospitals.

    Conclusions: In our present series, bladder cancer recurrence of urothelial malignancy occurred in nearly half of the patients after surgical management of UTUC. Ureteric tumour was the only identifiable risk factor, thus patients with ureteric tumours may benefit from prophylactic intravesical chemoimmunotherapy. Bladder recurrence does not appear to affect the cancer-specific survival after surgical management of UTUC.

  20. Blocking Surgically Induced Lysyl Oxidase Activity Reduces the Risk of Lung Metastases

    Full Text Available Surgery remains the most successful curative treatment for cancer. However, some patients with early-stage disease who undergo surgery eventually succumb to distant metastasis. Here, we show that in response to surgery, the lungs become more vulnerable to metastasis due to extracellular matrix remodeling. Mice that undergo surgery or that are preconditioned with plasma from donor mice that underwent surgery succumb to lung metastases earlier than controls. Increased lysyl oxidase (LOX activity and expression, fibrillary collagen crosslinking, and focal adhesion signaling contribute to this effect, with the hypoxic surgical site serving as the source of LOX. Furthermore, the lungs of recipient mice injected with plasma from post-surgical colorectal cancer patients are more prone to metastatic seeding than mice injected with baseline plasma. Downregulation of LOX activity or levels reduces lung metastasis after surgery and increases survival, highlighting the potential of LOX inhibition in reducing the risk of metastasis following surgery.

    Effective communication and patient safety practices are paramount in health care. Surgical residents play an integral role in the perioperative team, yet their perceptions of patient safety remain unclear. We hypothesized that surgical residents perceive the perioperative environment as more unsafe than their faculty and operating room staff despite completing a required safety curriculum. Surgeons, anesthesiologists, and perioperative nurses in a large academic children's hospital participated in multifaceted, physician-led workshops aimed at enhancing communication and safety culture over a 3-y period. All general surgery residents from the same academic center completed a hospital-based online safety curriculum only. All groups subsequently completed the psychometrically validated safety attitudes questionnaire to evaluate three domains: safety culture, teamwork, and speaking up. Results reflect the percent of respondents who slightly or strongly agreed. Chi-square analysis was performed. Sixty-three of 84 perioperative personnel (75%) and 48 of 52 surgical residents (92%) completed the safety attitudes questionnaire. A higher percentage of perioperative personnel perceived a safer environment than the surgical residents in all three domains, which was significantly higher for safety culture (68% versus 46%, P = 0.03). When stratified into two groups, junior residents (postgraduate years 1-2) and senior residents (postgraduate years 3-5) had lower scores for all three domains, but the differences were not statistically significant. Surgical residents' perceptions of perioperative safety remain suboptimal. With an enhanced safety curriculum, perioperative staff demonstrated higher perceptions of safety compared with residents who participated in an online-only curriculum. Optimal surgical education on patient safety remains unknown but should require a dedicated, systematic approach. Copyright © 2015 Elsevier Inc. All rights reserved.

    Gross hip instability is a rare complication after hip arthroscopy, and there is limited literature surrounding this topic. This systematic review investigates cases of gross hip instability after arthroscopy and discusses the risk factors associated with this complication. A systematic search was performed in duplicate for studies investigating gross hip instability after hip arthroscopy up to October 2015. Study parameters including sample size, mechanism and type of dislocation, surgical procedure details, patient characteristics, postoperative rehabilitation protocol, and level of evidence were analyzed. The systematic review identified 9 case reports investigating gross hip instability after hip arthroscopy (10 patients). Anterior dislocation occurred in 66.7% of patients, and most injuries occurred with a low-energy mechanism. Common surgical factors cited included unrepaired capsulotomy (77.8%) and iliopsoas release (33.3%), whereas patient factors included female gender (77.8%), acetabular dysplasia (22.2%), and general ligamentous laxity (11.1%). Postoperative restrictions and protocols were variable and inconsistently reported, and their relation to post-arthroscopy instability was difficult to ascertain. This systematic review discussed various patient, surgical, and postoperative risk factors of gross hip instability after arthroscopy. Patient characteristics such as female gender, hip dysplasia, and ligamentous laxity may be risk factors for post-arthroscopy dislocation. Similarly, surgical risk factors for iatrogenic hip instability may include unrepaired capsulotomies and iliopsoas debridement, although the role of capsular closure in iatrogenic instability is not clear. The influences of postoperative restrictions and protocols on dislocation are also unclear in the current literature. Surgeons should be cognizant of these risk factors when performing hip arthroscopy and be mindful that these factors appear to occur in combination. Level IV

    To explore the impact of racial and ethnic diversity on the performance of cardiac surgical risk models, the Chinese SinoSCORE was compared with the Society of Thoracic Surgeons (STS) risk model in a diverse American population. The SinoSCORE risk model was applied to 13 969 consecutive coronary artery bypass surgery patients from twelve American institutions. SinoSCORE risk factors were entered into a logistic regression to create a 'derived' SinoSCORE whose performance was compared with that of the STS risk model. Observed mortality was 1.51% (66% of that predicted by STS model). The SinoSCORE 'low-risk' group had a mortality of 0.15%±0.04%, while the medium-risk and high-risk groups had mortalities of 0.35%±0.06% and 2.13%±0.14%, respectively. The derived SinoSCORE model had a relatively good discrimination (area under of the curve (AUC)=0.785) compared with that of the STS risk score (AUC=0.811; P=0.18 comparing the two). However, specific factors that were significant in the original SinoSCORE but that lacked significance in our derived model included body mass index, preoperative atrial fibrillation and chronic obstructive pulmonary disease. SinoSCORE demonstrated limited discrimination when applied to an American population. The derived SinoSCORE had a discrimination comparable with that of the STS, suggesting underlying similarities of physiological substrate undergoing surgery. However, differential influence of various risk factors suggests that there may be varying degrees of importance and interactions between risk factors. Clinicians should exercise caution when applying risk models across varying populations due to potential differences that racial, ethnic and geographic factors may play in cardiac disease and surgical outcomes.

    This study aimed to identify and compare risk factors for surgical site infection (SSI) and non-surgical site infections (non-SSIs), particularly urinary tract infection (UTI), after spine surgery. We retrospectively reviewed 825 patients (median age 59.0 years (range 33-70 years); 442 males) who underwent spine surgery at Kagoshima University Hospital from January 2009 to December 2014. Patient parameters were compared using the Mann-Whitney U and Fisher's exact tests. Risk factors associated with SSI and UTI were analyzed via the multiple logistic regression analysis. P operation time (P = 0.0019 and 0.0162, respectively) and ASA classification 3 (P = 0.0132 and 0.0356, respectively). The 1 week post-operative C-reactive protein (CRP) level was a risk factor for UTI (P = 0.0299), but not for SSI (P = 0.4996). There was no relationship between SSI and symptomatic UTI after spine surgery. Risk factors for post-operative SSI and UTI were operative time and ASA classification 3; 1 week post-operative CRP was a risk factor for UTI only.

    Despite the significant advances in the medical management of inflammatory bowel disease over the last decade, surgery continues to play a major role in the management of pediatric Crohn's disease (CD). While adult and pediatric Crohn's disease may share many clinical characteristics, pediatric Crohn's patients often have a more aggressive phenotype, and the operative care given by the pediatric surgeon to the newly diagnosed Crohn's patient is very different in nature to the surgical needs of adult patients after decades of disease progression. Children also have the unique surgical indication of growth failure to consider in the overall clinical decision making. While surgery is never curative in CD, it has the ability to transform the disease process in children, and appropriately timed operations may have tremendous impact on a child's physical and mental maturation. This monograph aims to address the surgical care of Crohn's disease in general, with a specific emphasis on the surgical treatment of small intestinal and ileocecal involvement.

    Full Text Available Background Oncoplastic surgery is being increasingly performed in Korean women; however, unlike Westerners, Korean women usually have small to moderate-sized breasts. To achieve better outcomes in reconstructed breasts, several factors should be considered to determine the optimal surgical method. Methods A total of 108 patients who underwent oncoplastic surgery from January 2013 to December 2016 were retrospectively investigated. We used various methods, including glandular tissue reshaping, latissimus dorsi (LD flap transposition, and reduction oncoplasty, to restore the breast volume and symmetry. Results The mean weight of the tumor specimens was 40.46 g, and the ratio of the tumor specimen weight to breast volume was 0.12 g/mL in the patients who underwent glandular tissue reshaping (n=59. The corresponding values were 101.47 g and 0.14 g/mL, respectively, in the patients who underwent reduction oncoplasty (n=17, and 82.54 g and 0.20 g/mL, respectively, in those treated with an LD flap (n=32. Glandular tissue reshaping was mostly performed in the upper outer quadrant, and LD flap transposition was mostly performed in the lower inner quadrant. No major complications were noted. Most patients were satisfied with the aesthetic results. Conclusions We report satisfactory outcomes of oncoplastic surgical procedures in Korean patients. The results regarding specimen weight and the tumor-to-breast ratio of Asian patients will be a helpful reference point for determining the most appropriate oncoplastic surgical technique.

    Objective: To investigate risk factors of rupture of internal carotid artery resection during carotid body tumor resection and to summarize our treatment experience. Methods: During the period from 1991 to 2016, rupture of internal carotid artery occurred in 27 patients (28 tumors) during surgical resection of carotid body tumor in the First Affiliated Hospital of Sun Yat-sen University. Their clinical and follow-up data were retrospectively collected and analyzed. For all patients underwent surgical resection during this period, Logistic regression analysis was used to investigate the risk factors of intraoperative rupture of internal carotid artery. Results: Of these 28 tumors, there were 15 (53.6%) tumors with diameter≥5 cm and 20 (71.4%) Shamblin Ⅲ tumors. Intraoperatively, shunt was applied for 8 (28.6%) cases. Thirteen (46.4%) patients underwent ligation of external carotid artery, while 2 (7.1%) patients accepted resection of cranial nerves. Direct closure/patchplasty, autologous vessels or graft reconstruction was used in 16, 10 and 2 cases, respectively. Postoperatively, stroke occurred in 4(14.3%) cases and cranial nerve deficit in 15 (53.6%) cases. During a median length of 36 (14-125) months, cranial nerve deficit persisted in 5 cases. Follow-up radiologic examination indicated 3 (10.7%) cases of targeted vessel occlusion. However, no new-onset stroke was identified. Among all patients underwent surgical resection of carotid body tumor, female ( OR =3.650, P =0.012), age≤25 years old ( OR =3.710, P =0.013) and Shamblin Ⅲ tumor ( OR =4.631, P =0.008) increase the risks of intraoperative carotid artery rupture. Conclusions: Shamblin Ⅲ tumor is the predictor of rupture of internal carotid artery. Intraoperative, properly increased blood pressure, intraoperative heparinization and use of shunt for those cases without well-compensated cranial collateral arteries are likely to decreasing the incidence of stroke.

    Full Text Available Background: Different studies underline the use of pre-operative antibiotic prophylaxis in clean surgeries like herniotomy and inguinal orchiopexy. But, the meta-analyses do not recommend nor discard the use of prophylactic pre-operative antibiotics. The scarcity of controlled clinical trials in paediatric population further vitiates the matter. This study assessed the difference in the rate of early post-operative wound infection cases in children who received single dose of pre-operative antibiotics and children who did not receive antibiotics after inguinal herniotomy and orchiopexy. Materials and Methods: This randomised prospective study was conducted in Paediatric Surgery department of PGIMER Chandigarh. Out of 251 patients, 112 patients were randomised to the case group and 139 were ascribed to the control group. The patients in control group were given a standard regimen of single dose of intravenous antibiotic at the time of induction followed by 3-4 days of oral antibiotic. Case group patients underwent the surgical procedure in similar manner with no antibiotic either at the time of induction or post-operatively. Results: The incidence of surgical site infection in case group was 3.73 % and that in control group was 2.22%. The observed difference in the incidence of surgical site infection was statistically insignificant (P value = 0.7027. The overall infection rate in case and control group was 2.89%. Conclusions: Our preliminary experience suggests that there is no statistically significant difference in the proportion of early post-operative wound infection between the patients who received single dose of pre-operative antibiotics and the patients who received no antibiotics after inguinal herniotomy and orchiopexy. The risk of surgical site infection in paediatric heriotomies does not increase even if the child′s weight is less than his/her expected weight for age.

    Intratumoral lung abscess is a secondary lung abscess that is considered to be fatal. Therefore, surgical procedures, although high-risk, have sometimes been performed for intratumoral lung abscesses. However, no studies have examined the surgical outcomes of non-small cell lung cancer patients with intratumoral lung abscesses. The aim of this study was to investigate the surgical and survival outcomes of non-small cell lung cancer patients with intratumoral lung abscesses. Eleven consecutive non-small cell lung cancer patients with intratumoral lung abscesses, who had undergone pulmonary resection at our institution between January 2007 and December 2015, were retrospectively analysed. The post-operative prognoses were investigated and prognostic factors were evaluated. Ten of 11 patients were male and one patient was female. The median age was 64 (range, 52-80) years. Histopathologically, 4 patients had Stage IIA, 2 patients had Stage IIB, 2 patients had Stage IIIA, and 3 patients had Stage IV tumors. The median operative time was 346 min and the median amount of bleeding was 1327 mL. The post-operative morbidity and mortality rates were 63.6% and 0.0%, respectively. Recurrence of respiratory infections, including lung abscesses, was not observed in all patients. The median post-operative observation period was 16.1 (range, 1.3-114.5) months. The 5-year overall survival rate was 43.3%. No pre-operative, intra-operative, or post-operative prognostic factors were identified in the univariate analyses. Surgical procedures for advanced-stage non-small cell lung cancer patients with intratumoral lung abscesses, although high-risk, led to satisfactory post-operative mortality rates and acceptable prognoses.

    The U.S. Centers for Medicare & Medicaid Services (CMS) has been considering the implementation of a mandatory bundled payment program, the Surgical Hip and Femur Fracture Treatment (SHFFT) model. However, bundled payments without appropriate risk adjustment may be inequitable to providers and may restrict access to care for certain patients. The SHFFT proposal includes adjustment using the Diagnosis-Related Group (DRG) and geographic location. The goal of the current study was to identify and quantify patient factors that could improve risk adjustment for SHFFT bundled payments. We retrospectively reviewed a 5% random sample of Medicare data from 2008 to 2012. A total of 27,898 patients were identified who met SHFFT inclusion criteria (DRG 480, 481, and 482). Reimbursement was determined for each patient over the bundle period (the surgical hospitalization and 90 days of post-discharge care). Multivariable regression was performed to test demographic factors, comorbidities, geographic location, and specific surgical procedures for associations with reimbursement. The average reimbursement was $23,632 ± $17,587. On average, reimbursements for male patients were $1,213 higher than for female patients (p payments; e.g., reimbursement for those ≥85 years of age averaged $2,282 ± $389 less than for those aged 65 to 69 (p reimbursement, but dementia was associated with lower payments, by an average of $2,354 ± $243 (p reimbursement ranging from $22,527 to $24,033. Less common procedures varied by >$20,000 in average reimbursement (p reimbursement (p reimbursed by an average of $10,421 ± $543 more than DRG 482. Payments varied significantly by state (p ≤ 0.01). Risk adjustment incorporating specific comorbidities demonstrated better performance than with use of DRG alone (r = 0.22 versus 0.15). Our results suggest that the proposed SHFFT bundled payment model should use more robust risk-adjustment methods to ensure that providers are reimbursed fairly and that

    Perioperative physicians occasionally encounter situations where central venous catheters placed preoperatively turn out to be unnecessary. The purpose of this retrospective study is to identify the unnecessary application of central venous catheter placement and determine the factors associated with the unnecessary application of central venous catheter placement. Using data from institutional perioperative central venous catheter surveillance, we analysed data from 1,141 patients who underwent central venous catheter placement. We reviewed the central venous catheter registry and medical charts and allocated registered patients into those with the proper or with unnecessary application of central venous catheter according to standard indications. Multivariate analysis was used to identify factors associated with the unnecessary application of central venous catheter placement. In 107 patients, representing 9.38% of the overall population, we identified the unnecessary application of central venous catheter placement. Multivariate analysis identified emergencies at night or on holidays (odds ratio [OR] 2.109, 95% confidence interval [95% CI] 1.021-4.359), low surgical risk (OR=1.729, 95% CI 1.038-2.881), short duration of anesthesia (OR=0.961/10min increase, 95% CI 0.945-0.979), and postoperative care outside of the intensive care unit (OR=2.197, 95% CI 1.402-3.441) all to be independently associated with the unnecessary application of catheterization. Complications related to central venous catheter placement when the procedure consequently turned out to be unnecessary were frequently observed (9/107) compared with when the procedure was necessary (40/1034) (p=0.032, OR=2.282, 95% CI 1.076-4.842). However, the subsequent multivariate logistic model did not hold this significant difference (p=0.0536, OR=2.115, 95% CI 0.988-4.526). More careful consideration for the application of central venous catheter is required in cases of emergency surgery at night or on

    The management of patients with unruptured intracranial aneurysms (UIAs) is controversial. We aimed to assess the natural history of UIAs and evaluate the surgical results. We analyzed 154 patients (181 saccular UIAs) with no history of subarachnoid hemorrhage (SAH) from a different aneurysm. Aneurysms were detected by magnetic resonance angiography (MRA) or by 3-dimensional CT angiography. Although the most frequent reason for the diagnosis was routine brain examinations of healthy patients or a vague symptom such as headache or dizziness, 15 patients were symptomatic. The natural history in patients who did not have surgery (follow-up group: 76 cases, 95 aneurysms) was assessed, and the surgical outcome of UIAs (surgical group: 78 cases, 86 aneurysms) was evaluated. Among 76 patients in the follow-up group, 7 had SAH. The mean latency period to aneurysm rupture was 3.2 months. The aneurysms with subsequent bleeding ranged from 5 to 25 mm (19.3 mm on average), whereas those without ranged from 1 to 28 mm (4.5 mm on average). The rupture rates of UIAs in anterior and posterior circulation were 6.2% and 14.3%, respectively. All ruptured cases were females. Mortality and morbidity associated with UIAs in the follow-up group were 3.9% and 3.9%, respectively. In the surgical group, no mortality was noted. Permanent morbidity associated with prospective repair of UIAs was 5.1%, although the morbidity of the patients with preoperative Rankin scores of 0 or 1 was 1.3%. Transient morbidity was observed in 6 patients (7.7%) with the size of the aneurysm 19.8 mm on average. The natural history and surgical results in patients with UIAs are modified by several factors including aneurysm size and location, the patient's age and gender, the medical status and the patient's preoperative Rankin score. The present results indicated that these factors should be considered in deciding whether to treat UIAs, and that careful assessment of the surgical benefits might be essential

    Full Text Available Pneumatosis intestinalis (PI is the presence of gas within the wall of the gastrointestinal tract and represents a tremendous spectrum of conditions and outcomes, ranging from benign diseases to abdominal sepsis and death. It is seen with increased frequency in patients who are immunocompromised because of steroids, chemotherapy, radiation therapy, or AIDS. PI may result from intraluminal bacterial gas entering the bowel wall due to increased mucosal permeability caused by defects in bowel wall lymphoid tissue. We present a case of PI who was treated conservatively and in whom PI resolved completely and we present a literature review of conservative management. It is not difficult to make a precise diagnosis of PI and to prevent unnecessary surgical intervention, especially when PI presents without clinical evidence of peritonitis. Conservative treatment is possible and safe for selected patients. Awareness of these rare causes of PI and close observation of selected patients without peritonitis may prevent unnecessary invasive surgical explorations.

    To evaluate the treatment time and the anterior and posterior teeth movement pattern as closing extraction space for the Class III surgical patients facilitated by accelerated osteogenic orthodontic treatment. There were 10 skeletal Class III patients in accelerated osteogenic orthodontic group (AOO) and 10 patients in control group. Upper first premolars were extracted in all patients. After leveling and alignment (T2), corticotomy was performed in the area of maxillary anterior teeth to accelerate space closing.Study models of upper dentition were taken before orthodontic treatment (T1) and after space closing (T3). All the casts were laser scanned, and the distances of the movement of incisors and molars were digitally measured. The distances of tooth movement in two groups were recorded and analyzed. The alignment time between two groups was not statistically significant. The treatment time in AOO group from T2 to T3 was less than that in the control group (less than 9.1 ± 4.1 months). The treatment time in AOO group from T1 to T3 was less than that in the control group (less than 6.3 ± 4.8 months), and the differences were significant (P 0.05). Accelerated osteogenic orthodontic treatment could accelerate space closing in Class III surgical patients and shorten preoperative orthodontic time. There were no influence on the movement pattern of anterior and posterior teeth during pre-surgical orthodontic treatment.

    We evaluated the surgical risks associated with fibrocavernous pulmonary tuberculosis by retrospectively examining chest computed tomography (CT) scans. We reviewed the records of 40 patients who underwent pulmonary resection for fibrocavernous pulmonary tuberculosis, for whom preoperative CT scans were available. The disease was categorized as class I, defined as a cavity within one lobe without remarkable pleural thickness, in 21 patients; class II, defined as a cavity extending beyond one lobe or within one lobe with remarkable pleural thickness, in 10 patients; and class III, defined as bilateral cavities, in 9 patients. Four of the nine patients with bilateral cavities underwent bilateral pulmonary resection and five underwent unilateral pulmonary resection. The study parameters were intraoperative blood loss, operative time, hospital stay, major operative morbidity, and hospital death. Intraoperative blood loss and operative time were significantly greater and hospital stay was significantly longer in patients with advanced disease (P=0.046, P=0.000, and P=0.143, respectively). Major surgical morbidity mainly occurred in association with advanced disease (P=0.028) at the following incidences: class I, 5%; class II, 30%; class III, 44.4%. Two hospital deaths occurred, both following bilateral pulmonary resection for class III disease, accounting for an overall 5% mortality rate. The surgical risks associated with fibrocavernous pulmonary tuberculosis were well correlated with anatomic involvement, according to the extent of cavitation and the severity of pleural thickness, as depicted by CT. Staged pulmonary resection or the combination of one-sided resection with other modalities is recommended for the treatment of bilateral cavities. (author)

    To assess the incidence of hospital-acquired, surgery-related pressure injury (ulcers) and identify risk factors for these injuries. We used a prospective cohort study to investigate the research question. The study was conducted at a major metropolitan hospital in Brisbane, Australia. Five hundred thirty-four adult patients booked for any surgical procedure expected to last more than 30 minutes were eligible for inclusion. Patients who provided informed consent for study participation were assessed for pressure ulcers, using the European Pressure Ulcer Advisory Panel and National Pressure Ulcer Advisory Panel Guidelines, before entering the operating room and again in the post-anesthetic care unit (PACU). Research nurses and all PACU nurses were trained in skin assessment and in pressure ulcer staging. Patients were not assessed again after their discharge from the PACU. Seven patients (1.3%) had existing pressure injuries (ulcers) and a further 6 (1.3%) developed a surgery-related pressure ulcer. Risk factors associated with surgery-related pressure injuries were similar to non-surgically related risks and included older age, skin condition, and being admitted from a location other than one's own home. Length of surgery was not associated with pressure ulcer development in this cohort. Perioperative nurses play an important role in identifying existing or new pressure injuries. However, many of these nurses are unfamiliar with pressure ulcer classification, so education in this area is essential. Although the incidence of surgically acquired pressure ulcers was low in this cohort, careful skin inspection before and after surgery provides an opportunity for early treatment and may prevent existing lesions progressing to higher stages.

    Growing evidence shows a causal role of high-risk humane papillomavirus (HPV) infections in the development of head and neck cancer. A recent case report shows two patients suffering from tonsillar cancer without any risk factors apart from their work as gynecologists doing laser ablations and loop electrosurgical excision procedures (LEEP). The aim of the present investigation is to evaluate whether surgical plume resulting from routine LEEPs of HSIL of the cervix uteri might be contaminated with the DNA of high-risk HPV. The prospective pilot study is done at the Department of Gynecology and Obstetrics of the University of Lübeck, Germany. The primary outcome was defined as HPV subtype in resected cone and in surgical plume resulting from LEEPs of HSIL of the cervix uteri. Plume resulting from LEEPs was analyzed using a Whatman FTA Elute Indicating Card which was placed in the tube of an exhaust suction device used to remove the resulting aerosols. For detection of HPV and analysis of its subtype, the novel EUROArray HPV test was performed. Resected cones of LEEPs were evaluated separately for HPV subtypes. Four samples of surgical plume resulting from routine LEEPs indicated contamination with high-risk HPV and showed the same HPV subtype as identified in the resected cones. Surgical plume resulting from routine LEEPs for HSIL of the cervix uteri has the risk of contamination with high-risk HPV. Further investigations of infectiousness of surgical plume are necessary for evaluation of potential hazards to involved healthcare professionals.

    Surgical site infection is one of the most common complications following ankle fracture surgery. These infections are associated with substantial morbidity and lead to increased resource utilization. Identification of risk factors is crucial for developing strategies to prevent these complications. We performed an age and sex-matched case-control study to identify patient and surgery-related risk factors for deep surgical site infection following operative ankle fracture treatment. We identified 1923 ankle fracture operations performed in 1915 patients from 2006 through 2009. A total of 131 patients with deep infection were identified and compared with an equal number of uninfected control patients. Risk factors for infection were determined with use of conditional logistic regression analysis. The incidence of deep infection was 6.8%. Univariate analysis showed diabetes (odds ratio [OR] = 2.2, 95% confidence interval [CI] = 1.0, 4.9), alcohol abuse (OR = 3.8, 95% CI = 1.6, 9.4), fracture-dislocation (OR = 2.0, 95% CI = 1.2, 3.5), and soft-tissue injury (a Tscherne grade of ≥1) (OR = 2.6, 95% CI = 1.3, 5.3) to be significant patient-related risk factors for infection. Surgery-related risk factors were suboptimal timing of prophylactic antibiotics (OR = 1.9, 95% CI = 1.0, 3.4), difficulties encountered during surgery, (OR = 2.1, 95% CI = 1.1, 4.0), wound complications (OR = 4.8, 95% CI = 1.6, 14.0), and fracture malreduction (OR = 3.4, 95% CI = 1.3, 9.2). Independent risk factors for infection identified by multivariable analyses were tobacco use (OR = 3.7, 95% CI = 1.6, 8.5) and a duration of surgery of more than ninety minutes (OR = 2.5, 95% CI = 1.1, 5.7). Cast application in the operating room was independently associated with a decreased infection rate (OR = 0.4, 95% CI = 0.2, 0.8). We identified several modifiable risk factors for deep surgical site infection following operative treatment of ankle fractures.

    The results of treatment of 127 patients, suffering cervix uteri cancer stage IIB in period of 1998 - 2012 yrs, were analyzed. Complications of surgical stage of the combined treatment have had occurred in 40.9% patients, including 40.5% patients, to whom neoadjuvant chemotherapy was conducted and in 41.5%--radiation therapy (RTH). The main postoperative complications--retroperitoneal lymphatic cysts--were revealed in 35.4% patients. The factors, raising the risk of postoperative complications occurrence, are following: the primary tumor spreading, metastatic affection of lymphatic nodes of pelvic cavity, preoperative conduction of RTH or chemotherapy.

    Full Text Available Background: Patients who had received surgical services at Bellin Hospital reported anxiety with the surgical flow. This study tested the hypothesis that the introduction of a surgical navigator, someone who guided the patient and their accompanying others throughout the surgical process, would improve patient satisfaction. Methods: Ambulatory surgical patients were randomized to control and study groups. The study group patients were assigned a surgical navigator. Prior to discharge from the hospital, patients were asked to complete a patient satisfaction survey. Results: The study group had significantly higher mean scores (P value ≤ 0.026, top box scores (P value ≤ 0.021, and positive comments. Conclusion: The addition of a surgical navigator to the perioperative process significantly enhanced patient satisfaction in ambulatory surgical patients.

    To question the usefulness of the lab analysis considered routine testing for the identification of abnormalities in the surgical care. To determine the percentage of unnecessary laboratory tests in the preoperative assessment as well as to estimate the unnecessary expenses. A descriptive, cross-sectional study of patients referred for surgical evaluation between January 1st and March 31st 2013. The database of laboratory testing and electronic files were reviewed. Reference criteria from surgical services were compared with the tests requested by the family doctor. In 65% of the patients (n=175) unnecessary examinations were requested, 25% (n=68) were not requested the tests that they required, and only 10% of the patients were requested laboratory tests in accordance with the reference criteria (n=27). The estimated cost in unnecessary examinations was $1,129,552 in a year. The results were similar to others related to this theme, however, they had not been revised from the perspective of the first level of attention regarding the importance of adherence to the reference criteria which could prevent major expenditures. It is a priority for leaders and operational consultants in medical units to establish strategies and lines of action that ensure compliance with institutional policies so as to contain spending on comprehensive services, and which in turn can improve the medical care.

    In haemophilia, the ankle joint is one of the most common and earliest joints affected by recurrent bleeding, commonly resulting in end-stage ankle osteoarthritis during early adulthood. The surgical treatment of haemophilic ankle arthropathy is challenging. This review aims to highlight the literature addressing clinical outcomes following the most common approaches for different stages of haemophilia-induced ankle osteoarthritis: arthroscopic debridement, joint distraction arthroplasty, supramalleolar osteotomies, total ankle replacement, and ankle arthrodesis. A systematic literature review was performed using established medical literature databases. The following information was retrieved from the literature: patients' demographics, surgical technique, duration of follow-up, clinical outcome including pain relief and complication rate. A total of 42 clinical studies published between 1978 and 2015 were included in the systematic literature review. Eight and 34 studies had prospective and retrospective design, respectively. The most common studies were level IV studies (64.3%). The orthopaedic treatment of patients with haemophilic ankle osteoarthritis is often challenging and requires complete and careful preoperative assessment. In general, both joint-preserving and joint non-preserving procedure types can be performed. All specific relative and absolute contraindications should be considered to achieve appropriate postoperative outcomes. The current literature demonstrated that orthopaedic surgeries, with appropriate indication, in patients with haemophilic ankle arthropathy result in good postoperative results comparable to those observed in non-haemophiliacs. The surgical treatment should be performed in a setting with the ability to have multidisciplinary management, including expertise in haematology. © 2016 John Wiley & Sons Ltd.

    Full Text Available Abstract Despite remarkable developments in the use of surgical techniques, ergonomic advancements in the operating room, and implementation of bundles, surgical site infections (SSIs remain a substantial burden, associated with increased morbidity, mortality and healthcare costs. National and international recommendations to prevent SSIs have been published, including recent guidelines by the World Health Organization, but implementation into clinical practice remains an unresolved issue. SSI improvement programs require an integrative approach with measures taken during the pre-, intra- and postoperative care from the numerous stakeholders involved. The current SSI prevention strategies have focused mainly on the role of healthcare workers (HCWs and procedure related risk factors. The importance and influence of patient participation is becoming an increasingly important concept and advocated as a means to improve patient safety. Novel interventions supporting an active participative role within SSI prevention programs have not been assessed. Empowering patients with information they require to engage in the process of SSI prevention could play a major role for the implementation of recommendations. Based on available scientific evidence, a panel of experts evaluated options for patient involvement in order to provide pragmatic recommendations for pre-, intra- and postoperative activities for the prevention of SSIs. Recommendations were based on existing guidelines and expert opinion. As a result, 9 recommendations for the surgical patient are presented here, including a practice brief in the form of a patient information leaflet. HCWs can use this information to educate patients and allow patient engagement.

SSI improvement programs require an integrative approach with measures taken during the pre-, intra- and postoperative care from the numerous stakeholders involved. The current SSI prevention strategies have focused mainly on the role of healthcare workers (HCWs) and procedure related risk factors. The importance and influence of patient participation is becoming an increasingly important concept and advocated as a means to improve patient safety. Novel interventions supporting an active participative role within SSI prevention programs have not been assessed. Empowering patients with information they require to engage in the process of SSI prevention could play a major role for the implementation of recommendations. Based on available scientific evidence, a panel of experts evaluated options for patient involvement in order to provide pragmatic recommendations for pre-, intra- and postoperative activities for the prevention of SSIs. Recommendations were based on existing guidelines and expert opinion. As a result, 9 recommendations for the surgical patient are presented here, including a practice brief in the form of a patient information leaflet. HCWs can use this information to educate patients and allow patient engagement.

    To assess how much information communicated to patients is understood and retained after preoperative discussion of upper extremity procedures. A prospective study was designed by recruiting patients prior to undergoing upper extremity surgical procedures after a detailed discussion of their operative technique, postoperative care and treatment outcomes. Patients were given the same 20-item questionnaire to fill out twice, at two pre operative visits. An independent evaluator filled out a third questionnaire as a control. Various discussion points of the survey were compared among the 3 questionnaires and retained information and perceived comprehension were evaluated. The average patients' age was 50.3 (27-75) years The average time between the two surveys preoperative 1 and preoperative 2 was 40.7 (7-75) days,. The average patient had approximately 2 years of college or an associate's degree. Patients initially retained 73% (52-90%) of discussion points presented during preoperative 1 and 61% (36-85%) of the information at preoperative 2 p = .002. 50% of patients felt they understood 100% of the discussion, this dropped to only 10% at their preoperative 2 visit. 15% of our patients did not know what type of anesthesia they were having at preoperative 2. A communication barrier between patients and physicians exists when patients are informed about their preoperative surgical discussion. The retention of information presented is worsened with elapsing time from the initial preoperative discussion to the second preoperative visit immediately prior to surgery. Methods to enhance patients' retention of information prior to surgery must be sought and implemented which will improve patients' treatment outcome.

    Background: Problems regarding bowel elimination are quite common in patients undergoing abdominal surgery. Objectives: To determine constipation risk before the surgery, bowel elimination during postoperative period, and the factors affecting bowel elimination. Patients and Methods: This is a cross-sectional study. It was conducted in a general surgery ward of a university hospital in Zonguldak, Turkey between January 2013 and May 2013. A total of 107 patients were included in the study, who were selected by convenience sampling. Constipation Risk Assessment Scale (CRAS), patient information form, medical and nursing records were used in the study. Results: The mean age of the patients was found to be 55.97 ± 15.74 (year). Most of the patients have undergone colon (37.4%) and stomach surgeries (21.5%). Open surgical intervention (83.2%) was performed on almost all patients (96.3%) under general anesthesia. Patients were at moderate risk for constipation with average scores of 11.71 before the surgery. A total of 77 patients (72%) did not have bowel elimination problem during postoperative period. The type of the surgery (P < 0.05), starting time for oral feeding after the surgery (P < 0.05), and mobilization (P < 0.05) were effective on postoperative bowel elimination. Conclusions: There is a risk for constipation after abdominal surgery. Postoperative practices are effective on the risk of constipation. PMID:26380107

    The traditional implementation of the risk-adjusted Bernoulli cumulative sum (CUSUM) chart for monitoring surgical outcome quality requires waiting a pre-specified period of time after surgery before incorporating patient outcome information. We propose a simple but powerful implementation of the risk-adjusted Bernoulli CUSUM chart that incorporates outcome information as soon as it is available, rather than waiting a pre-specified period of time after surgery. A simulation study is presented that compares the performance of the traditional implementation of the risk-adjusted Bernoulli CUSUM chart to our improved implementation. We show that incorporating patient outcome information as soon as it is available leads to quicker detection of process deterioration. Deterioration of surgical performance could be detected much sooner using our proposed implementation, which could lead to the earlier identification of problems. © The Author 2017.

  10. Risk Factors for Postoperative Fibrinogen Deficiency after Surgical Removal of Intracranial Tumors.

    Directory of Open Access Journals (Sweden)

    Naili Wei

    Full Text Available Higher levels of fibrinogen, a critical element in hemostasis, are associated with increased postoperative survival rates, especially for patients with massive operative blood loss. Fibrinogen deficiency after surgical management of intracranial tumors may result in postoperative intracranial bleeding and severely worsen patient outcomes. However, no previous studies have systematically identified factors associated with postoperative fibrinogen deficiency. In this study, we retrospectively analyzed data from patients who underwent surgical removal of intracranial tumors in Beijing Tiantan Hospital date from 1/1/2013to12/31/2013. The present study found that patients with postoperative fibrinogen deficiency experienced more operative blood loss and a higher rate of postoperative intracranial hematoma, and they were given more blood transfusions, more plasma transfusions, and were administered larger doses of hemocoagulase compared with patients without postoperative fibrinogen deficiency. Likewise, patients with postoperative fibrinogen deficiency had poorer extended Glasgow Outcome Scale (GOSe, longer hospital stays, and greater hospital expenses than patients without postoperative fibrinogen deficiency. Further, we assessed a comprehensive set of risk factors associated with postoperative fibrinogen deficiency via multiple linear regression. We found that body mass index (BMI, the occurrence of postoperative intracranial hematoma, and administration of hemocoagulasewere positively associated with preoperative-to-postoperative plasma fibrinogen consumption; presenting with a malignant tumor was negatively associated with fibrinogen consumption. Contrary to what might be expected, intraoperative blood loss, the need for blood transfusion, and the need for plasma transfusion were not associated with plasma fibrinogen consumption. Considering our findings together, we concluded that postoperative fibrinogen deficiency is closely associated with

    Introduction An increasing proportion of the population is living into their nineties and beyond. These high risk patients are now presenting more frequently to both elective and emergency surgical services. There is limited research looking at outcomes of general surgical procedures in nonagenarians and centenarians to guide surgeons assessing these cases. Methods A retrospective analysis was conducted of all patients aged ≥90 years undergoing elective and emergency general surgical procedures at a tertiary care facility between 2009 and 2015. Vascular, breast and endocrine procedures were excluded. Patient demographics and characteristics were collated. Primary outcomes were 30-day and 90-day mortality rates. The impact of ASA (American Society of Anesthesiologists) grade, operation severity and emergency presentation was assessed using multivariate analysis. Results Overall, 161 patients (58 elective, 103 emergency) were identified for inclusion in the study. The mean patient age was 92.8 years (range: 90-106 years). The 90-day mortality rates were 5.2% and 19.4% for elective and emergency procedures respectively (p=0.013). The median survival was 29 and 19 months respectively (p=0.001). Emergency and major gastrointestinal operations were associated with a significant increase in mortality. Patients undergoing emergency major colonic or upper gastrointestinal surgery had a 90-day mortality rate of 53.8%. Conclusions The risk for patients aged over 90 years having an elective procedure differs significantly in the short term from those having emergency surgery. In selected cases, elective surgery carries an acceptable mortality risk. Emergency surgery is associated with a significantly increased risk of death, particularly after major gastrointestinal resections.

    Postoperative unplanned readmissions are costly and decrease patient satisfaction; however, little is known about this complication in pediatric surgery. The purpose of this study was to determine rates and predictors of unplanned readmission in a multi-institutional cohort of pediatric surgical patients. Unplanned 30-day readmissions following general and thoracic surgical procedures in children readmission per 30 person-days were determined to account for varied postoperative length of stay (pLOS). Patients were randomly divided into 70% derivation and 30% validation cohorts which were used for creation and validation of a risk model for readmission. Readmission occurred in 1948 (3.6%) of 54,870 children for a rate of 4.3% per 30 person-days. Adjusted predictors of readmission included hepatobiliary procedures, increased wound class, operative duration, complications, and pLOS. The predictive model discriminated well in the derivation and validation cohorts (AUROC 0.710 and 0.701) with good calibration between observed and expected readmission events in both cohorts (p>.05). Unplanned readmission occurs less frequently in pediatric surgery than what is described in adults, calling into question its use as a quality indicator in this population. Factors that predict readmission including type of procedure, complications, and pLOS can be used to identify at-risk children and develop prevention strategies. III. Copyright © 2017 Elsevier Inc.

    Orthopaedic surgical-site infections prolong hospital stays, double rehospitalization rates, and increase healthcare costs. Additionally, patients with orthopaedic surgical-site infections (SSI) have substantially greater physical limitations and reductions in their health-related quality of life. However, the risk factors for SSI after operative fracture care are unclear. We determined the incidence and quantified modifiable and nonmodifiable risk factors for SSIs in patients with orthopaedic trauma undergoing surgery. We retrospectively indentified, from our prospective trauma database and billing records, 1611 patients who underwent 1783 trauma-related procedures between 2006 and 2008. Medical records were reviewed and demographics, surgery-specific data, and whether the patients had an SSI were recorded. We determined which if any variables predicted SSI. Six factors independently predicted SSI: (1) the use of a drain, OR 2.3, 95% CI (1.3-3.8); (2) number of operations OR 3.4, 95% CI (2.0-6.0); (3) diabetes, OR 2.1, 95% CI (1.2-3.8); (4) congestive heart failure (CHF), OR 2.8, 95% CI (1.3-6.5); (5) site of injury tibial shaft/plateau, OR 2.3, 95% CI (1.3-4.2); and (6) site of injury, elbow, OR 2.2, 95% CI (1.1-4.7). The risk factors for SSIs after skeletal trauma are most strongly determined by nonmodifiable factors: patient infirmity (diabetes and heart failure) and injury complexity (site of injury, number of operations, use of a drain). Level II, prognostic study. See the Guideline for Authors for a complete description of levels of evidence.

    With the development of population aging in our country, the incidence of gastrointestinal cancer is increasing. The risk of developing gastrointestinal cancer in elderly over 75 years was 5-6 times and the risk of death of gastrointestinal cancer was 7-8 times of the general population. As compared to non-elderly, the incidence of gastric cancer was not decreased obviously but the total incidence of colorectal cancer was increased more quickly. Therefore, screening of gastrointestinal cancer should be performed in the elderly for early discovery, diagnosis and treatment. Because of the insidious onset of the illness in elderly patients, gastrointestinal cancers are mostly diagnosed at advanced or late stage (stage III or IV). Well differentiated cancer is more common, such as papillary or tubular adenocarcinoma. Lauren type, Borrmann II or III are more common in gastric cancer, which are relatively favorable. Compared with non-elderly patients, many elderly patients also suffer from comorbid diseases with higher operation risk and postoperative complication rates. Therefore, we must pay great attention to the perioperative management and the surgical operation for the elderly patients. In this paper, several key issues involved the development trend of incidence and mortality of gastrointestinal cancer, the clinicopathological characteristics, the comorbidity and surgical treatment in the elderly patients with gastrointestinal cancer will be elaborated, aiming at promoting further attention to the clinical therapeutic strategies, management measures and prognostic factors for the elderly patients with gastrointestinal cancer.

    To evaluate the impact of preoperative biliary drainage on surgical morbidity in hilar cholangiocarcinoma patients underwent surgery. One hundred and eleven consecutive patients with hilar cholangiocarcinoma whose serum total bilirubin (TBIL) level > 85 micromol/L and underwent surgery in the period from June 1998 to August 2007 were enrolled. There were 67 male and 44 female patients, aged from 26 to 82 years old with a mean of 56 years old. Fifty-five patients underwent preoperative biliary drainage with a mean of 11.4 d of drainage period (drainage group), the other (n = 56) were the non-drainage group. The preoperative TBIL level of drainage group was (154 +/- 69) micromol/L, which was significantly lower than the value of pre-drainage (256 +/- 136) micromol/L (P = 0.000) and the value of non-drainage group (268 +/- 174) micromol/L (P = 0.005). ALT and GGT levels could be lowered by preoperative biliary drainage. The postoperative complications of these two groups were comparable (36.3% vs. 28.6%, P = 0.381). Four patients in drainage group and 5 patients in non-drainage group died of liver failure. Multivariate logistic regression indicated that hepatectomy (OR = 0.284, P = 0.003) was the independent risk factor associated with postoperative morbidity. Bismuth-Corlette classification (OR = 0.211, P = 0.028) was the independent risk factor linked to postoperative mortality. Preoperative biliary drainage could alleviate liver injury due to hyperbilirubin, but it could not decrease the surgical morbidity and postoperative mortality. Concomitant hepatectomy and Bismuth-Corlette classification were independent risk factors linked to surgical risks.

    To evaluate the incidence and risk factors of postsurgical site infections (SSIs) in elective neurosurgical procedures in patients treated with an ultrashort antibiotic protocol. In this consecutive series of 1747 patients treated with elective neurosurgery and ultrashort prophylactic antibiotic therapy at the Fondazione Istituto Nazionale Neurologico "Carlo Besta" in Milan, the rate of SSIs was 0.7% (13 patients). When only clean neurosurgery was considered, there were 11 such SSIs (1.52%) in 726 craniotomies and one SSI (0.15) in 663 spinal operations. The antibiotic protocol was prolonged in every case of external communication as cerebrospinal fluid leaks or external drainages. The infection rate of the whole series was low (0.72%), and a risk factor identified for SSIs in clean neurosurgery was longer surgery duration. The relative risk estimate was 12.6 for surgeries lasting 2 hours and 24.3 for surgeries lasting 3 or more hours. Patients aged older than 50 years had a lower risk of developing SSI with a relative risk of 0.23 when compared with patients aged younger than 50 years. The present series reports a low incidence of SSIs for elective neurosurgery, even for high-risk complex craniotomies performed for tumor removal. Given that an antibiotic protocol prolongation was used to pretreat any early signs of infection and external communication, the protocol was appropriate for the case mix. The two identified risk factors (surgical duration > 2 hours and middle-aged patients [16-50 yr]) may be indicators of other factors, such as the level of surgical complexity and poor neurological outcome.

    The prevention of medical and surgical harm remains an important public health problem despite increased awareness and implementation of safety programs. Successful introduction and maintenance of surgical safety programs require both surgeon leadership and collaborative surgeon-hospital alignment. Documentation of success of such surgical safety programs in orthopaedic practice is limited. We describe the scope of orthopaedic surgical patient safety issues, define critical elements of orthopaedic surgical safety, and outline leadership roles for orthopaedic surgeons needed to establish and sustain a culture of safety in contemporary healthcare systems. We identified the most common causes of preventable surgical harm based on adverse and sentinel surgical events reported to The Joint Commission. A comprehensive literature review through a MEDLINE(®) database search (January 1982 through April 2012) to identify pertinent orthopaedic surgical safety articles found 14 articles. Where gaps in orthopaedic literature were identified, the review was supplemented by 22 nonorthopaedic surgical references. Our final review included 36 articles. Six important surgical safety program elements needed to eliminate preventable surgical harm were identified: (1) effective surgical team communication, (2) proper informed consent, (3) implementation and regular use of surgical checklists, (4) proper surgical site/procedure identification, (5) reduction of surgical team distractions, and (6) routine surgical data collection and analysis to improve the safety and quality of surgical patient care. Successful surgical safety programs require a culture of safety supported by all six key surgical safety program elements, active surgeon champions, and collaborative hospital and/or administrative support designed to enhance surgical safety and improve surgical patient outcomes. Further research measuring improvements from such surgical safety systems in orthopaedic care is needed.

    Purpose: Although positive surgical margins are generally associated with a higher risk of local-regional recurrence (LRR) for most solid tumors, their significance after mastectomy remains unclear. We sought to clarify the influence of the mastectomy margin on the risk of LRR. Methods and Materials: The retrospective cohort consisted of 397 women who underwent mastectomy and no radiation for newly diagnosed invasive breast cancer from 1998-2005. Time to isolated LRR and time to distant metastasis (DM) were evaluated by use of cumulative-incidence analysis and competing-risks regression analysis. DM was considered a competing event for analysis of isolated LRR. Results: The median follow-up was 6.7 years (range, 0.5-12.8 years). The superficial margin was positive in 41 patients (10%) and close (≤2 mm) in 56 (14%). The deep margin was positive in 23 patients (6%) and close in 34 (9%). The 5-year LRR and DM rates for all patients were 2.4% (95% confidence interval, 0.9-4.0) and 3.5% (95% confidence interval, 1.6-5.3) respectively. Fourteen patients had an LRR. Margin status was significantly associated with time to isolated LRR (P=.04); patients with positive margins had a 5-year LRR of 6.2%, whereas patients with close margins and negative margins had 5-year LRRs of 1.5% and 1.9%, respectively. On univariate analysis, positive margins, positive nodes, lymphovascular invasion, grade 3 histology, and triple-negative subtype were associated with significantly higher rates of LRR. When these factors were included in a multivariate analysis, only positive margins and triple-negative subtype were associated with the risk of LRR. Conclusions: Patients with positive mastectomy margins had a significantly higher rate of LRR than those with a close or negative margin. However, the absolute risk of LRR in patients with a positive surgical margin in this series was low, and therefore the benefit of postmastectomy radiation in this population with otherwise favorable features

    Pancreatic duct stone (PDS) is a common complication of chronic pancreatitis. Surgery is a common therapeutic option for PDS. In this study we assessed the surgical procedures for PDS in patients with chronic pancreatitis at our hospital. Between January 2004 and September 2009, medical records from 35 patients diagnosed with PDS associated with chronic pancreatitis were retrospectively reviewed and the patients were followed up for up to 67 months. The 35 patients underwent ultrasonography, computed tomography, or both, with an overall accuracy rate of 85.7%. Of these patients, 31 underwent the modified Puestow procedure, 2 underwent the Whipple procedure, 1 underwent simple stone removal by duct incision, and 1 underwent pancreatic abscess drainage. Of the 35 patients, 28 were followed up for 4-67 months. There was no postoperative death before discharge or during follow-up. After the modified Puestow procedure, abdominal pain was reduced in patients with complete or incomplete stone clearance (P>0.05). Steatorrhea and diabetes mellitus developed in several patients during a long-term follow-up. Surgery, especially the modified Puestow procedure, is effective and safe for patients with PDS associated with chronic pancreatitis. Decompression of intraductal pressure rather than complete clearance of all stones predicts postoperative outcome.

    Epilepsy is a frequent complication of central nervous system (CNS) infections. Post-infectious epilepsy is commonly refractory to medical treatment and plays a pivotal role for the poor long-term outcome of CNS infections. To provide an overview of clinical characteristics and risk factors of seizures associated with CNS infections. In addition, to summarize the state of the art of anticonvulsive treatment and the pre-surgical evaluation process in refractory cases. A comprehensive literature search for articles published between January 1970 and December 2011 was carried out. The occurrence of seizures during the acute course of meningitis, encephalitis and brain abscess is the main risk factor for the development of post-infectious epilepsy. There is a shortage of trials evaluating the efficacy of prophylactic and symptomatic treatment during the course of acute infection. Moreover, there are no randomized-controlled trials studying anticonvulsive drugs and their combinations for the management of post-infectious epilepsy. In a selected group of patients, however, medically refractory focal epilepsy is potentially curable by surgery. Further studies are required to improve the pathogenetic understanding of post-infectious epilepsy in order to develop preventive measures as well as to evaluate additional medical and surgical treatment strategies for the patients currently not considered for surgery. © 2012 The Author(s) European Journal of Neurology © 2012 EFNS.

    Background: Spondylolithesis is forward slipping of upper vertebra in relation to its lower one, which at times requires surgery. The objective of present study is to document the outcome of surgical treatment in spondylolisthesis of lumbosacral region. Methods: We reviewed outcome of surgery in 45 patients with spondylolisthesis. Improvement in pain intensity, neurological status and union achieved after surgery was studied. All patients requiring surgical treatment were included in the study. The patients were operated by single spine surgeon. A proforma was made for each patient and records were kept in a custom built Microsoft access database. Results: Majority of our patient were in 4th and 5th decade with some male domination. Pain was main indication for surgery which was excruciating in 6, severe in 33, and moderate in 6 cases. The neurological status was normal in 34 cases while 11 patients had some deficit. L5-S1 was affected in 26, L4-L5 in 13 and multi or high level was found in rest of cases. Slip grade was measured with Meyerding grades, 18 had grade II, 15 had I, 9 had III and 3 had IV spondylolisthesis. Posterior lumbar inter body fusion (PLIF) was done in 24 patients, posterolateral, transforaminal lumbar inter body and anterior inter body fusion in others. Translaminar screw fixation, transpedicular transdiscal transcorporial and Delta fixation in some cases. Pedicle screw fixation was done in most cases, AO fixator internae and 4.5 mm screw in others. Average follow up was 2 years and 5 months, max 5 years and minimum 6 months. Pain relief was achieved in 82%, neurological improvement 60% and union in 91% cases. There was no deterioration of neurological status, two implant failure and one wound infection. Conclusion: Surgical procedure for Spondylolisthesis must be individualised. Young patients with spondylolysis can be treated with osteosynthesis and sparing of motion segment. PLIF provides satisfactory results in majority of low to moderate

    Full Text Available Objective: A study of accessibility of surgical care to elderly patients (aged 60 and above with valvular heart disease has been conducted at the BSCCS "Bakulev Scientific Center of Cardiovascular Surgery» of the Ministry of Health of the Russian Federation. Methods: A retrospective analysis of structure of hospitalizations of 1726 patients, that were hospitalized between 2009 and 2010 at the BSCCS for surgical correction of valvular heart disease was performed. Results: Our study demonstrated that age, on one hand, is not the most significant barrier in the geographical accessibility of cardiac surgical care. On the other hand, it can influence the availability in general, taking into account other factors (urban / rural areas, the presence of cardiac surgical clinics, and clinical status. Provision of cardiac surgical care for patients with heart defects at the BSCCS per 1 million population varies considerably in the context of federal districts and is 0.4 for the Siberian Federal District 30 for the Central Federal District (the highest is 42 for the Moscow Region. Conclusion: Thus, our study demonstrated accessibility of surgical care for elderly patients is the highest for the urban areas with specialized cardiac surgery centers, where patients referred from rural regions

    To investigate in surgical gynaecological patients the types of health problems arising or persisting up to six weeks after discharge and the effectiveness of telephone advice. The decreasing length of hospital stay has increased the need for specific instructions about the postdischarge period. Telephone advice could be a valuable tool to address this problem. To our knowledge, postdischarge health problems and the value of telephone advice have not been investigated among gynaecological patients. Randomised controlled trial. Gynaecological patients expected to stay in the ward longer than 24 hour were invited to participate. A pilot study showed that wound healing, pain, mobility, urination, defecation and vaginal bleeding were the most common health problems postdischarge. Based on that information, guidelines were formulated that were used by trained nurses to give telephone advice to the intervention group (n=235), in addition to the usual care. The control group of gynaecological patients (n=233) received usual care only. Of all 468 participants, about 50% were operated for general gynaecology. At discharge, wound pain (56%), mobility problems (54%) and constipation (27%) were the most frequently mentioned problems in both groups. Participants who completely followed the advice with regard to wound healing (p=0.02), pain (p=0.01), vaginal bleeding (p=0.03) and mobility (p=0.04) experienced greater improvement than participants who did not follow, or only partly followed, the advice. The telephone advice appears to make a significant contribution to help gynaecological surgical patients to solve or reduce their postdischarge health problems. The positive effect of such advice can be interpreted as an improvement in the quality of life of the postoperative gynaecological patient. © 2010 Blackwell Publishing Ltd.

    Full Text Available The Ki-67 labelling index is significant for the management of breast cancer. However, the concordance of Ki-67 expression between preoperative biopsy and postoperative surgical specimens has not been well evaluated. This study aimed to find the correlation in Ki-67 expression between biopsy and surgical specimens and to determine the clinicopathological risk factors associated with discordant values.Ki-67 levels were immunohistochemically measured using paired biopsy and surgical specimens in 310 breast cancer patients between 2008 and 2013. ΔKi-67 was calculated by postoperative Ki-67 minus preoperative levels. The outliers of ΔKi-67 were defined as [lower quartile of ΔKi-67-1.5 × interquartile range (IQR] or (upper quartile + 1.5 × IQR and were evaluated according to clinicopathological parameters by logistic regression analysis.The median preoperative and postoperative Ki-67 levels were 10 (IQR, 15 and 10 (IQR, 25, respectively. Correlation of Ki-67 levels between the two specimens indicated a moderately positive relationship (coefficient = 0.676. Of 310 patients, 44 (14.2% showed outliers of ΔKi-67 (range, ≤-20 or ≥28. A significant association with poor prognostic factors was found among these patients. Multivariate analysis determined that significant risk factors for outliers of ΔKi-67 were tumor size >1 cm, negative progesterone receptor (PR expression, grade III cancer, and age ≤35 years. Among 171 patients with luminal human epidermal growth factor receptor 2-negative tumors, breast cancer subtype according to preoperative or postoperative Ki-67 levels discordantly changed in 46 (26.9% patients and a significant proportion of patients with discordant cases had ≥1 risk factor.Ki-67 expression showed a substantial concordance between biopsy and surgical specimens. Extremely discordant Ki-67 levels may be associated with aggressive tumor biology. In patients with luminal subtype disease, clinical application of Ki-67

    Simulated patient care has gained acceptance as a medical education tool but is underused in surgical training. To improve resident clinical management in critical situations relevant to the surgical patient, high-fidelity full patient simulation training was instituted at Baystate Medical Center in 2005 and developed during successive years. We define surgical patient simulation as clinical management performed in a high fidelity environment using a manikin simulator. This technique is intended to be specifically modeled experiential learning related to the knowledge, skills, and behaviors that are fundamental to patient care. We report 3 academic years' use of a patient simulation curriculum. Learners were PGY 1-3 residents; 26 simulated patient care experiences were developed based on (1) designation as a critical management problem that would otherwise be difficult to practice, (2) ability to represent the specific problem in simulation, (3) relevance to the American Board of Surgery (ABS) certifying examination, and/or (4) relevance to institutional quality or morbidity and mortality reports. Although training started in 2005, data are drawn from the period of systematic and mandatory training spanning from July 2006 to June 2009. Training occurred during 1-hour sessions using a computer-driven manikin simulator (METI, Sarasota, Florida). Educational content was provided either before or during presimulation briefing sessions. Scenario areas included shock states, trauma and critical care case management, preoperative processes, and postoperative conditions and complications. All sessions were followed by facilitated debriefing. Likert scale-based multi-item assessments of core competency in medical knowledge, patient care, diagnosis, management, communication, and professionalism were used to generate a performance score for each resident for each simulation (percentage of best possible score). Performance was compared across PGYs by repeated

    The Centers for Medicare and Medicaid Services include patient experience as a core component of its Value-Based Purchasing program, which ties financial incentives to hospital performance on a range of quality measures. However, it remains unclear whether patient satisfaction is an accurate marker of high-quality surgical care. To determine whether hospital performance on a patient satisfaction survey is associated with objective measures of surgical quality. Retrospective observational study of participating American College of Surgeons National Surgical Quality Improvement Project (ACS NSQIP) hospitals. We used data from a linked database of Medicare inpatient claims, ACS NSQIP, the American Hospital Association annual survey, and Hospital Compare from December 2, 2004, through December 31, 2008. A total of 103 866 patients older than 65 years undergoing inpatient surgery were included. Hospitals were grouped by quartile based on their performance on the Hospital Consumer Assessment of Healthcare Providers and Systems survey. Controlling for preoperative risk factors, we created hierarchical logistic regression models to predict the occurrence of adverse postoperative outcomes based on a hospital's patient satisfaction scores. Thirty-day postoperative mortality, major and minor complications, failure to rescue, and hospital readmission. Of the 180 hospitals, the overall mean patient satisfaction score was 68.0% (first quartile mean, 58.7%; fourth quartile mean, 76.7%). Compared with patients treated at hospitals in the lowest quartile, those at the highest quartile had significantly lower risk-adjusted odds of death (odds ratio = 0.85; 95% CI, 0.73-0.99), failure to rescue (odds ratio = 0.82; 95% CI, 0.70-0.96), and minor complication (odds ratio = 0.87; 95% CI, 0.75-0.99). This translated to relative risk reductions of 11.1% (P = .04), 12.6% (P = .02), and 11.5% (P = .04), respectively. No significant relationship was noted between patient satisfaction

    Unfavourable hemodynamics in heart failure patients implanted with left ventricular assist devices (LVAD), due to non-optimal surgical configurations and patient management, strongly influence thrombogenicity. This is consistent with the increase in devastating thromboembolic complications (specifically thrombosis and stroke) in patients, even as the risk of thrombosis inside the device decreases with modern designs. Inflow cannula and outflow graft surgical configurations have been optimized via patient-specific modeling that computes the thrombogenic potential with a combination of Eulerian (endothelial) wall shear stress and Lagrangian (platelet shear history) tracking. Using this view of hemodynamics, the benefits of intermittent aortic valve opening (promoting washout and reducing stagnant flow in the aortic valve region) have been assessed in managing the patient's residual native cardiac output. The use of this methodology to understand the contribution of the hemodynamics in the flow surrounding the LVAD itself to thrombogenesis show promise in developing holistic patient-specific management strategies to minimize stroke risk and enhance efficacy of LVAD therapy.

    Objective: To determine the number of hospitalized patients at risk for developing venous thromboembolism (VTE) / deep vein thrombosis (DVT), identifying the most common risk factor and to document the use of thromboprophylaxis. Study Design: Observational and cross-sectional study. Place and Duration of Study: Chandka Medical College Hospital, Larkana, from October to December 2011. Methodology: A total of 170 patients underwent this study and these included 51 (30%) from general medical, and 119 (70%) from surgical units. Inclusion and exclusion criteria were defined and data was collected on printed format. VTE risk assessment was done according to Caprini Model and criteria defined by the American College of Chest Physicians- ACCP. Results: Out of 170 patients, 91 were male and 79 female with mean age of 39 +- 16 years. According to ACCP criteria for VTE risk assessment, 20% (n=34) patients were identified to be at low risk, 20% (n=34) at moderate risk, 47.65% (n=81) at high risk and 12.35% (n=21) at very high risk of developing VTE. The commonest risk factor significantly identified was immobility (54.7%, p < 0.005), followed by advancing age (41.17%, p < 0.005) and obesity (18.23%). The most common risk factor in all types of surgical patients was anaesthesia for more than 45 minutes 82.35% (n=98/119) and in medical patients advancing age 45% (n=23/51). Only 6 (3.5%) patients received thromboprophylaxis, all were surgical patients of very high-risk category. Conclusion: Majority of studied hospitalized patients were at high risk of developing VTE. Immobility was the commonest risk factor for developing VTE, followed by advancing age and obesity. Very few hospitalized patients actually received thromboprophylaxis. (author)

    Recently, the patient's role in preventing adverse events has been emphasized. Patients who are more knowledgeable about safety issues are more likely to engage in safety initiatives. Therefore, nurses need to develop techniques and tools that increase patients' knowledge in preventing adverse events. For this reason, an educational smartphone application for patient safety called "Safe Patients" was developed through an iterative process involving a literature review, expert consultations, and pilot testing of the application. To determine the effect of "Safe Patients," it was implemented for patients in surgical units in a tertiary hospital in South Korea. The change in patients' knowledge about patient safety was measured using seven true/false questions developed in this study. A one-group pretest and posttest design was used, and a total of 123 of 190 possible participants were tested. The percentage of correct answers significantly increased from 64.5% to 75.8% (P effectively improve patients' knowledge of safety issues. This will ultimately empower patients to engage in safe practices and prevent adverse events related to surgery.

    To evaluate the effectiveness of surgical treatment performed in patients with double elevator palsy (DEP). Patients diagnosed with congenital DEP between April 2003 and March 2007 were included in the study. The cases with positive traction test had inferior rectus (IR) recession followed by full tendon width muscle transposition Knapp surgery or partial tendon width transposition operation, while those without positive traction test underwent transposition procedure alone. Transposition surgery was combined with recession and resection of horizontal rectus muscles in patients with exotropia according to the amount of horizontal deviation. Eyelid surgery was applied in patients with ptosis following strabismus surgery. The average age of 13 patients was 14+/-32.5 years (range, 3-60 years). Five patients (38%) were female and 8 patients (62%) were male. The mean preoperative hypotropia was decreased from 29.2+/-3.5 prism diopters (PD) (range, 16-45 PD) to 2.6+/-2.8 PD (range, 0-6 PD) postoperatively. The median amount of horizontal deviation in patients with exotropia (n=4) was 30 PD (range, 25-45 PD) preoperatively; it was reduced to 2 PD (range, 0-8 PD) postoperatively. Mean follow-up period was 14.1+/-2.8 months (range, 6-31 months). Five patients (38%) underwent eyelid surgery, and all achieved cosmetically satisfactory results. Transposition surgery alone or combined with IR recession is an effective procedure in treatment of double elevator palsy. In patients with moderate horizontal deviations, recession and resection of horizontal rectus muscles combined with transposition provide correction of the horizontal deviation at the same time.

    There is a general consensus by intensivists and nonsurgical providers that surgeons hesitate to withdraw life-sustaining therapy on their operative patients despite a patient's or surrogate's request to do so. The objective of this study was to examine the culture and practice of surgeons to assess attitudes and concerns regarding advance directives for their patients who have high-risk surgical procedures. A qualitative investigation using one-on-one, in-person interviews with open-ended questions about the use of advance directives during perioperative planning. Consensus coding was performed using a grounded theory approach. Data accrual continued until theoretical saturation was achieved. Modeling identified themes and trends, ensuring maximal fit and faithful data representation. Surgical practices in Madison and Milwaukee, WI. Physicians involved in the performance of high-risk surgical procedures. None. We describe the concept of surgical "buy-in," a complex process by which surgeons negotiate with patients a commitment to postoperative care before undertaking high-risk surgical procedures. Surgeons describe seeking a commitment from the patient to abide by prescribed postoperative care, "This is a package deal, this is what this operation entails," or a specific number of postoperative days, "I will contract with them and say, 'look, if we are going to do this, I am going to need 30 days to get you through this operation.'" "Buy-in" is grounded in a surgeon's strong sense of responsibility for surgical outcomes and can lead to surgeon unwillingness to operate or surgeon reticence to withdraw life-sustaining therapy postoperatively. If negotiations regarding life-sustaining interventions result in treatment limitation, a surgeon may shift responsibility for unanticipated outcomes to the patient. A complicated relationship exists between the surgeon and patient that begins in the preoperative setting. It reflects a bidirectional contract that is assumed by

    Full Text Available Background: Degenerative lumbar scoliosis surgery can lead to development of adjacent segment degeneration (ASD after lumbar or thoracolumbar fusion. Its incidence, risk factors, morbidity and correlation between radiological and clinical symptoms of ASD have no consensus. We evaluated the correlation between the occurrence of radiologic adjacent segment disease and certain imperative parameters. Materials and Methods: 98 patients who had undergone surgical correction and lumbar/thoracolumbar fusion with pedicle screw instrumentation for degenerative lumbar scoliosis with a minimum 5 year followup were included in the study. We evaluated the correlation between the occurrence of radiologic adjacent segment disease and imperative patient parameters like age at operation, sex, body mass index (BMI, medical comorbidities and bone mineral density (BMD. The radiological parameters taken into consideration were Cobb′s angle, angle type, lumbar lordosis, pelvic incidence, intercristal line, preoperative existence of an ASD on plain radiograph and magnetic resonance imaging (MRI and surgical parameters were number of the fusion level, decompression level, floating OP (interlumbar fusion excluding L5-S1 level and posterolateral lumbar interbody fusion (PLIF. Clinical outcomes were assessed with the Visual Analogue Score (VAS and Oswestry Disability Index (ODI. Results: ASD was present in 44 (44.9% patients at an average period of 48.0 months (range 6-98 months. Factors related to occurrence of ASD were preoperative existence of disc degeneration (as revealed by MRI and age at operation ( P = 0.0001, 0.0364. There were no statistically significant differences between radiological adjacent segment degeneration and clinical results (VAS, P = 0.446; ODI, P = 0.531. Conclusions: Patients over the age of 65 years and with preoperative disc degeneration (as revealed by plain radiograph and MRI were at a higher risk of developing ASD.

    Full Text Available Abstract In children with Prader Willi syndrome (PWS, besides growth hormone (GH therapy, control of the food environment and regular exercise, surgical treatment of scoliosis deformities seems the treatment of choice, even though the risks of spinal surgery in this specific population is very high. Therefore the question arises as to whether the risks of spinal surgery outweigh the benefits in a condition, which bears significant risks per se. The purpose of this systematic review of the Pub Med literature was to find mid or long-term results of spinal fusion surgery in patients with PWS, and to present the conservative treatment in a case study of nine patients with this condition. Methods Types of studies included; all kinds of studies; retrospective and prospective ones, which reported upon the outcome of scoliosis surgery in patients with PWS. Types of participants included: patients with scoliosis and PWS. Type of intervention: surgery. Search strategy for identification of the studies; Pub Med; limited to English language and bibliographies of all reviewed articles. Nine patients with PWS from our data-base treated conservatively have been found, being 19 years or over at the time this study has been performed. The results of conservative management are described and related to the natural history and treatment results found in the Pub Med review. Results From 2210 titles displayed in the Pub Med database with the key word being "Prader Willi syndrome", 5 different papers were displayed at the date of the search containing some information on the outcome of surgery and none appeared to contain a mid or long-term follow-up. The PWS patients treated conservatively from our series all stayed below 70° and some of which improved. Discussion If the curve of scoliosis patients with PWS can be kept within certain limits (usually below 70 degrees conservatively, this treatment seems to have fewer complications than surgical treatments.

    Our goals were to evaluate the risk factors predisposing to saphenous vein harvest surgical site infection (HSSI), the microbiology implicated, associated outcomes including 30-day mortality, and identify opportunities for prevention of infection. All patients undergoing coronary artery bypass grafting (CABG) procedures from January 2000 through September 2004 were included. Data were collected on preoperative, intraoperative, and postoperative factors, in addition to microbiology and outcomes. Eighty-six of 3578 (2.4%) patients developed HSSI; 28 (32.6%) of them were classified as deep. The median time to detection was 17 (range, 4-51) days. An organism was identified in 64 (74.4%) cases; of them, a single pathogen was implicated in 50 (78%) cases. Staphylococcus aureus was the most frequently isolated pathogen: 19 (38% [methicillin-susceptible S aureus (MSSA) = 12, methicillin-resistant S aureus (MRSA) = 7]). Gram-negative organisms were recovered in 50% of cases, with Pseudomonas aeruginosa predominating in 11 (22%) because of a single pathogen. Multiple pathogens were identified in 14 (22%) cases. The 30-day mortality was not significantly different in patients with or without HSSI. Multivariate analysis showed age, diabetes mellitus, obesity, congestive heart failure, renal insufficiency, and duration of surgery to be associated with increased risk. Diabetes mellitus, obesity, congestive heart failure, renal insufficiency, and duration of surgery were associated with increased risk for HSSI. S aureus was the most frequently isolated pathogen.

However, it remains unclear whether one type of dressing is better than any other type for preventing ulcer development during surgery. Therefore, we compared the effects of ceramide 2-containing hydrocolloid dressing with film dressings in high-risk patients with regard to reducing the incidence of pressure ulcer development during surgery. Patients and methods: A prospective, randomized, open-label, clinical trial was conducted involving patients who were at a high risk of developing pressure ulcers at a Japanese hospital. The intervention group received ceramide 2-containing hydrocolloid dressings (n=66, and the control group received film dressings (n=64. The primary end point was the incidence rate of pressure ulcer development in both groups; skin damage, such as blanchable erythema, skin discoloration, contact dermatitis, and stripped skin, was recorded as the secondary end point. The relative risk (RR and 95% confidence interval (CI were assessed to compare the probability ratios of pressure ulcer development between the groups. Results: There were significantly fewer patients who developed pressure ulcers in the intervention group than in the control group (RR, 0.37; 95% CI, 0.05–0.99; P=0.04. In the post hoc subgroup analysis, the superiority of the intervention group was more marked when patients had a lower body mass index (P=0.02, lower albumin values (P=0.07, and operation time of 3 hours or more and less than 6 hours (P=0.03.

    The objectives of the research were to compare the outcomes of pancreatoduodenectomy (PD) (Kausch-Whipple or Traverso-Longmire) and resection with drainage operations (RDO) (Frey or Partingtone-Rochelle) in patients suffering from chronic pancreatitis (CP), in management of pain syndrome and quality of life provided by these kinds of surgical procedures. From 2002 to 2008 sixteen patients suffering from CP underwent PD and 16 underwent RDO. Treatment results for the two groups were analyzed with respect to postoperative complications and results of the questionnaire MOS SF-36 v.2(TM). In the immediate postoperative period more complications were observed in the PD group (a<0.05). In both groups a positive effect on removing the painful syndrome and improvement of the quality of life (p<0.01) were observed. In the PD group there were the best results of management by General Health difference criterion (a<0.01). A greater improvement of Physical Functiong value (a<0.01) was noticed in patients who underwent RDO. Both PD and RDO adequately remove pain syndrome and improve the quality of life in patients suffering from CP. Under equal conditions the preference should be given to RDO, as improvement in life quality of operated patients is greater.

    To investigate nutritional risk and its relationship with clinical outcome in children hospitalized in the surgical department, and to provide a scientific basis for clinical nutrition management. Nutritional risk screening was performed on 706 children hospitalized in the surgical department using the Screening Tool for Risk on Nutritional Status and Growth. The data on nutritional support during hospitalization, incidence of infectious complications, length of hospital stay, post operative length of hospital stay and total hospital expenses were recorded. Of the 706 cases, 11.5% had high nutritional risk, 46.0% had moderate nutritional risk, and 42.5% had low nutritional risk. Congenital hypertrophic pyloric stenosis, intestinal obstruction and congenital heart disease were the three most common types of high nutritional risk. The incidence of high nutritional risk was significantly higher in infants than in other age groups (Pnutritional risk received parenteral nutrition. Children with high nutritional risk were significantly more likely to have weight loss than children with low nutritional risk (Pnutritional risk had significantly increased incidence of infectious complications, length of hospital stay, post operative length of hospital stay and total hospital expenses compared with those with moderate or low nutritional risk (Pnutritional risk is seen in children hospitalized in the surgical department. Nutritional risk score is correlated with clinical outcome. Nutritional support for these children is not yet properly provided. Nutritional risk screening and standard nutritional support should be widely applied among hospitalized children.

    Full Text Available Background. Postresective mandibular reconstruction is common in cases of oral and mandibular tumors. However, complications such as infection, plate exposure, or plate fracture can occur. We identified several significant risk factors of complications after reconstructive surgery and compared the effectiveness of different surgical techniques for reducing the incidence of complications. Methods. This study is a retrospective analysis of 28 oromandibular cancer cases that required reconstructive surgery between January 1999 and December 2011 at Kobe University Graduate School of Medicine in Japan. All cases were classified using Hashikawa’s CAT and Eichner’s classification methods. Then, we determined whether these classifications and different treatment or surgical methods were significantly related to complications. Results. Complications after mandibular reconstruction occurred in 10/28 patients (36%. Specifically, five patients had plate fractures, four had plate exposures, and one had an infection. Radiation therapy and closure without any flaps were significantly related to infection or plate exposure. The wrap-around technique of securing reconstruction plates was used in 14 cases, whereas the run-through technique was used in two cases. Conclusions. The success of mandibular reconstruction depends on both mechanical and biological factors, such as the location of defects, presence of occlusions, and the amount of vascularization of the flap.

    Postoperative respiratory complications (PRCs) increase hospitalization time, 30-day mortality and costs by up to $35 000. These outcomes measures have gained prominence as bundled payments have become more common. Results of recent quantitative effectiveness studies and clinical trials provide a framework that helps develop center-specific treatment guidelines, tailored to minimize the risk of PRCs. The implementation of those protocols should be guided by a local, respected, and visible facilitator who leads proper implementation while inviting center-specific input from surgeons, anesthesiologists, and other perioperative stakeholders. Preoperatively, patients should be risk-stratified for PRCs to individualize intraoperative choices and postoperative pathways. Laparoscopic compared with open surgery improves respiratory outcomes. High-risk patients should be treated by experienced providers based on locally developed bundle-interventions to optimize intraoperative treatment and ICU bed utilization. Intraoperatively, lung-protective ventilation (procedure-specific positive end-expiratory pressure utilization, and low driving pressure) and moderately restrictive fluid therapy should be used. To achieve surgical relaxation, high-dose neuromuscular blocking agents (and reversal agents) as well as high-dose opioids should be avoided; inhaled anesthetics improve surgical conditions while protecting the lungs. Patients should be extubated in reverse Trendelenburg position. Postoperatively, continuous positive airway pressure helps prevent airway collapse and protocolized, early mobilization improves cognitive and respiratory function.

    To develop a 30-day mortality risk index for noncardiac surgery that can be used to communicate risk information to patients and guide clinical management at the "point-of-care," and that can be used by surgeons and hospitals to internally audit their quality of care. Clinicians rely on the Revised Cardiac Risk Index to quantify the risk of cardiac complications in patients undergoing noncardiac surgery. Because mortality from noncardiac causes accounts for many perioperative deaths, there is also a need for a simple bedside risk index to predict 30-day all-cause mortality after noncardiac surgery. Retrospective cohort study of 298,772 patients undergoing noncardiac surgery during 2005 to 2007 using the American College of Surgeons National Surgical Quality Improvement Program database. The 9-point S-MPM (Surgical Mortality Probability Model) 30-day mortality risk index was derived empirically and includes three risk factors: ASA (American Society of Anesthesiologists) physical status, emergency status, and surgery risk class. Patients with ASA physical status I, II, III, IV or V were assigned either 0, 2, 4, 5, or 6 points, respectively; intermediate- or high-risk procedures were assigned 1 or 2 points, respectively; and emergency procedures were assigned 1 point. Patients with risk scores less than 5 had a predicted risk of mortality less than 0.50%, whereas patients with a risk score of 5 to 6 had a risk of mortality between 1.5% and 4.0%. Patients with a risk score greater than 6 had risk of mortality more than 10%. S-MPM exhibited excellent discrimination (C statistic, 0.897) and acceptable calibration (Hosmer-Lemeshow statistic 13.0, P = 0.023) in the validation data set. Thirty-day mortality after noncardiac surgery can be accurately predicted using a simple and accurate risk score based on information readily available at the bedside. This risk index may play a useful role in facilitating shared decision making, developing and implementing risk

    Comanagement of surgical patients is occurring more commonly among adult and pediatric patients. These systems of care can vary according to institution type, comanagement structure, and type of patient. Comanagement can impact quality, safety, and costs of care. We review these implications for pediatric surgical patients. © 2014 Society of Hospital Medicine.

    Availability of surgical site infection (SSI) surveillance rates challenges clinicians, healthcare administrators and leaders and the public. The purpose of this report is to demonstrate the consequences patient self-assessment strategies have on SSI reporting rates. We performed SSI surveillance among patients undergoing general surgery procedures, including telephone follow-up 30 days after surgery. Additionally we undertook a separate validation study in which we compared patient self-assessments of SSI with surgeon assessment. Finally, we performed a meta-analysis of similar validation studies of patient self-assessment strategies. There were 22/266 in-hospital SSIs diagnosed (8.3%), and additional 16 cases were detected through the 30-day follow-up. In total, the SSI rate was 16.8% (95% CI 10.1-18.5). In the validation survey, we found patient telephone surveillance to have a sensitivity of 66% (95% CI 40-93%) and a specificity of 90% (95% CI 86-94%). The meta-analysis included five additional studies. The overall sensitivity was 83.3% (95% CI 79-88%), and the overall specificity was 97.4% (95% CI 97-98%). Simulation of the meta-analysis results divulged that when the true infection rate is 1%, reported rates would be 4%; a true rate of 50%, the reported rates would be 43%. Patient self-assessment strategies in order to fulfill 30-day SSI surveillance misestimate SSI rates and lead to an erroneous overall appreciation of inter-institutional variation. Self-assessment strategies overestimate SSIs rate of institutions with high-quality performance and underestimate rates of poor performance. We propose such strategies be abandoned. Alternative strategies of patient follow-up strategies should be evaluated in order to provide valid and reliable information regarding institutional performance in preventing patient harm.

    Pelvic radiation therapy for cervical or vaginal cancer often leads to ovarian failure. To remove the ovaries from the radiation portal and preserve their function, they can be transposed to the lateral abdomen. Serial imaging studies in 14 patients who had undergone ovarian transposition (five bilateral, nine unilateral) were reviewed. Images obtained included 32 CT scans, 20 sonograms, and one MR image. Most transposed ovaries were located along the paracolic gutters near the iliac crests, creating an extrinsic mass effect on adjacent bowel. Detection of surgical clips on the ovary on CT scans allowed confident recognition of all 19 transposed ovaries. Cysts in the transposed ovaries, noted on most imaging studies, did not correlate with complications of pain or hormonal dysfunction. In one case, a large physiologic cyst in a transposed ovary distorted the cecum and was mistaken for a mucocele of the appendix. In another case, a large ovarian cyst was thought to be tumor recurrence or a lymphocele. These findings indicate that although the transposed ovaries can be recognized on CT scans by the surgical clips attached to the ovaries, the appearance of the ovary does not predict reliably the development of complications.

    Acute surgical patients are particularly vulnerable to human error. The Acute Physiological Support Team (APST) was created with the twin objectives of identifying high-risk acute surgical patients in the general wards and reducing both the incidence of error and impact of error on these patients. A number of error taxonomies were used to understand the causes of human error and a simple risk stratification system was adopted to identify patients who are particularly at risk of error. During the period November 2012-January 2013 a total of 101 surgical patients were cared for by the APST at Edendale Hospital. The average age was forty years. There were 36 females and 65 males. There were 66 general surgical patients and 35 trauma patients. Fifty-six patients were referred on the day of their admission. The average length of stay in the APST was four days. Eleven patients were haemo-dynamically unstable on presentation and twelve were clinically septic. The reasons for referral were sepsis,(4) respiratory distress,(3) acute kidney injury AKI (38), post-operative monitoring (39), pancreatitis,(3) ICU down-referral,(7) hypoxia,(5) low GCS,(1) coagulopathy.(1) The mortality rate was 13%. A total of thirty-six patients experienced 56 errors. A total of 143 interventions were initiated by the APST. These included institution or adjustment of intravenous fluids (101), blood transfusion,(12) antibiotics,(9) the management of neutropenic sepsis,(1) central line insertion,(3) optimization of oxygen therapy,(7) correction of electrolyte abnormality,(8) correction of coagulopathy.(2) CONCLUSION: Our intervention combined current taxonomies of error with a simple risk stratification system and is a variant of the defence in depth strategy of error reduction. We effectively identified and corrected a significant number of human errors in high-risk acute surgical patients. This audit has helped understand the common sources of error in the general surgical wards and will inform

    To assess the current prevalence of Hepatitis B and C virus in our set up. All patients who were operated during the study period. The detailed information about each patient was entered on a pre-designed questionnaire, including age, sex, type of operation, HBV and HCV screening test results, and presence of risk factors like: history of drug addiction, blood transfusion, family history of hepatitis, tattooing, viral vaccination, hospitalization, previous surgery, haemodialysis, etc. Amongst the total 275 patients, 27 (9.8%) had the Hepatitis virus: HBV-10, HCV-14 and HBV and HCV-3. Infection was more common among male patients and those between the ages of 41-50 years. Knowledge about Hepatitis risk factors is deficient, hence there should be more emphasis on public mass education programmes. Besides HBV vaccination should be carried out to reduce Hepatitis transmission. (author)

    The purpose of this study was to determine the incidence of, and risk factors for, surgical site infections in a contemporary cohort of women with endometrial carcinoma. We retrospectively studied 1164 women treated for endometrial carcinoma by hysterectomy at a single institution in 2007-2013. In all, 912 women (78.4%) had minimally invasive hysterectomy. Data on surgical site infections were collected from medical records. Univariate and multivariate analyses were used to identify risk factors for incisional and organ/space infections. Ninety-four women (8.1%) were diagnosed with a surgical site infection. Twenty women (1.7%) had an incisional infection and 74 (6.4%) had an organ/space infection. The associations of 17 clinico-pathologic and surgical variables were tested by univariate analyses. Those variables that were identified as potential risk factors in univariate analyses (p infections as dependent variables. Obesity (body mass index ≥ 30 kg/m(2)), diabetes, and long operative time (>80th centile) were independently associated with a higher risk of incisional infection, whereas minimally invasive surgery was associated with a smaller risk. Smoking, conversion to laparotomy, and lymphadenectomy were associated with a higher risk of organ/space infection. Organ/space infections comprised the majority of surgical site infections. Risk factors for incisional and organ/space infections differed. Minimally invasive hysterectomy was associated with a smaller risk of incisional infections but not of organ/space infections. © 2015 Nordic Federation of Societies of Obstetrics and Gynecology.

    Patient education is increasingly accessed with online resources and is essential for patient satisfaction and clinical outcomes. The average American adult reads at a seventh grade level, and the National Institute of Health (NIH) and the American Medical Association (AMA) recommend that information be written at a sixth-grade reading level. Health literacy plays an important role in the disease course and outcomes of all patients, including those with depression and likely other psychiatric disorders, although this is an area in need of further study. The purpose of this study was to collect and analyze written, online mental health resources on the Veterans Health Administration (VA) website, and other websites, using readability assessment instruments. An internet search was performed to identify written patient education information regarding mental health from the VA (the VA Mental Health Website) and top-rated psychiatric hospitals. Seven mental health topics were included in the analysis: generalized anxiety disorder, bipolar, major depressive disorder, posttraumatic stress disorder, schizophrenia, substance abuse, and suicide. Readability analyses were performed using the Gunning Fog Index, the Flesch-Kincaid Grade Level, the Coleman-Liau Index, the SMOG Readability Formula, and the Automated Readability Index. These scores were then combined into a Readability Consensus score. A two-tailed t-test was used to compare the mean values, and statistical significance was set at P readability consensus than six of the top psychiatric hospitals (P readability consensus for mental health information on all websites analyzed was 9.52. Online resources for mental health disorders are more complex than recommended by the NIH and AMA. Efforts to improve readability of mental health and psychosocial wellness resources could benefit patient understanding and outcomes, especially in patients with lower literacy. Surgical outcomes are correlated with patient mental

    Use of surgery for the treatment of infective endocarditis (IE) as related to surgical indications and operative risk for mortality has not been well defined. The International Collaboration on Endocarditis-PLUS (ICE-PLUS) is a prospective cohort of consecutively enrolled patients with definite IE from 29 centers in 16 countries. We included patients from ICE-PLUS with definite left-sided, non-cardiac device-related IE who were enrolled between September 1, 2008, and December 31, 2012. A total of 1296 patients with left-sided IE were included. Surgical treatment was performed in 57% of the overall cohort and in 76% of patients with a surgical indication. Reasons for nonsurgical treatment included poor prognosis (33.7%), hemodynamic instability (19.8%), death before surgery (23.3%), stroke (22.7%), and sepsis (21%). Among patients with a surgical indication, surgical treatment was independently associated with the presence of severe aortic regurgitation, abscess, embolization before surgical treatment, and transfer from an outside hospital. Variables associated with nonsurgical treatment were a history of moderate/severe liver disease, stroke before surgical decision, and Staphyloccus aureus etiology. The integration of surgical indication, Society of Thoracic Surgeons IE score, and use of surgery was associated with 6-month survival in IE. Surgical decision making in IE is largely consistent with established guidelines, although nearly one quarter of patients with surgical indications do not undergo surgery. Operative risk assessment by Society of Thoracic Surgeons IE score provides prognostic information for survival beyond the operative period. S aureus IE was significantly associated with nonsurgical management. © 2014 American Heart Association, Inc.

    Lymph node metastasis with extranodal extension represents one of the most important adverse prognostic factors for survival in patients with head and neck squamous cell carcinoma. We propose that extranodal extension occurs to differing extents. The aim of this study was to determine the prognostic significance of extranodal extension in patients with head and neck squamous cell carcinoma. Two hundred and ninety-eight patients with head and neck squamous cell carcinoma who underwent surgical resection and neck dissection were included. Cervical lymph nodes were classified into four categories: (i) pathological N negative, (ii) extranodal extension negative, (iii) non-surgical extranodal extension and (iv) surgical extranodal extension. Lymph node metastases were detected in 67.1% of laryngeal/hypopharyngeal cancer patients and 52.7% of oral cancer patients. The 3-year disease-specific survival rates for patients in the pathological N negative, extranodal extension negative, non-surgical extranodal extension and surgical extranodal extension groups were 90.9%, 79.6%, 63.8% and 48.3%, respectively. In laryngeal/hypopharyngeal cancer patients, surgical extranodal extension was associated with a significantly poorer disease-specific survival than a pathological N negative, extranodal extension negative or non-surgical extranodal extension status. In oral cancer patients, no significant differences were observed between the non-surgical and surgical extranodal extension groups. However, non-surgical extranodal extension was associated with a poorer disease-specific survival than a pathological N negative or extranodal extension negative status. Surgical extranodal extension was a poor prognostic factor in patients with head and neck squamous cell carcinoma. The prognostic significance of surgical extranodal extension differed between laryngeal/hypopharyngeal and oral cancer patients. The clinical significance of surgical extranodal extension was much greater for

    Risk assessment is an essential component in the decision-making process for the correct prevention and management of dental caries. Multiple risk factors and indicators have been proposed as targets in the assessment of risk of future disease, varying sometimes based on the age group at which...... they are targeted. Multiple reviews and systematic reviews are available in the literature on this topic. This chapter focusses primarily on results of reviews based on longitudinal studies required to establish the accuracy of caries risk assessment. These findings demonstrate that there is a strong body...... of evidence to support that caries experience is still, unfortunately, the single best predictor for future caries development. In young children, prediction models which include a variety of risk factors seem to increase the accuracy of the prediction, while the usefulness of additional risk factors...

    Cerebral palsy (CP) is a group of nonprogressive syndromes of posture and motor impairment associated with lesions of the immature brain. Spastic quadriplegia is the most severe form with a high incidence of scoliosis, back pain, respiratory compromise, pelvic obliquity, and poor sitting balance. Surgical stabilization of the spine is an effective technique for correcting deformity and restoring sitting posture. The decision to operate in this group of patients is challenging. The aim of this study is to determine the benefits of surgical correction of scoliosis in children with spastic quadriplegia, the adverse effects of this treatment, and what preoperative factors affect patient outcome after surgical correction. A systematic review was undertaken to identify studies describing benefits and adverse effects of surgery in spastic quadriplegia. Factors affecting patient outcome following surgical correction of scoliosis were assessed. Studies involving adults and nonspastic quadriplegia were excluded. A total of 10 case series and 1 prospective and 3 retrospective cohort studies met inclusion criteria. There was significant variation in the overall risk of complications (range, 10.9-70.9%), mortality (range, 2.8-19%), respiratory/pulmonary complications (range, 26.9-57.1%), and infection (range, 2.5-56.8%). Factors associated with a worse outcome were a significant degree of thoracic kyphosis, days in the intensive care unit, and poor nutritional status. Caregivers report a high degree of satisfaction with scoliosis surgery for children with spastic quadriplegia. There is limited evidence of preoperative factors that can predict patient outcome after scoliosis. There is a need for well-designed prospective studies of scoliosis surgery in spastic quadriplegia.

    The number of men undergoing cosmetic surgery is increasing in North America. To determine the incidence and risk factors of major complications in males undergoing cosmetic surgery, compare the complication profiles between men and women, and identify specific procedures that are associated with higher risk of complications in males. A prospective cohort of patients undergoing cosmetic surgery between 2008 and 2013 was identified from the CosmetAssure database. Gender specific procedures were excluded. Primary outcome was occurrence of a major complication in males requiring emergency room visit, hospital admission, or reoperation within 30 days of the index operation. Univariate and multivariate analysis evaluated potential risk factors for major complications including age, body mass index (BMI), smoking, diabetes, type of surgical facility, type of procedure, and combined procedures. Of the 129,007 patients, 54,927 underwent gender nonspecific procedures, of which 5801 (10.6%) were males. Women showed a higher mean age (46.4 ± 14.1 vs 45.2 ± 16.7 years, P procedures (RR 3.47), and combined procedures (RR 2.56). Aesthetic surgery in men is safe with low major complication rates. Modifiable predictors of complications included BMI and combined procedures.

    Full Text Available Abstract Background: Predicting mortality in patients undergoing transcatheter aortic valve implantation (TAVI remains a challenge. Objectives: To evaluate the performance of 5 risk scores for cardiac surgery in predicting the 30-day mortality among patients of the Brazilian Registry of TAVI. Methods: The Brazilian Multicenter Registry prospectively enrolled 418 patients undergoing TAVI in 18 centers between 2008 and 2013. The 30-day mortality risk was calculated using the following surgical scores: the logistic EuroSCORE I (ESI, EuroSCORE II (ESII, Society of Thoracic Surgeons (STS score, Ambler score (AS and Guaragna score (GS. The performance of the risk scores was evaluated in terms of their calibration (Hosmer–Lemeshow test and discrimination [area under the receiver–operating characteristic curve (AUC]. Results: The mean age was 81.5 ± 7.7 years. The CoreValve (Medtronic was used in 86.1% of the cohort, and the transfemoral approach was used in 96.2%. The observed 30-day mortality was 9.1%. The 30-day mortality predicted by the scores was as follows: ESI, 20.2 ± 13.8%; ESII, 6.5 ± 13.8%; STS score, 14.7 ± 4.4%; AS, 7.0 ± 3.8%; GS, 17.3 ± 10.8%. Using AUC, none of the tested scores could accurately predict the 30-day mortality. AUC for the scores was as follows: 0.58 [95% confidence interval (CI: 0.49 to 0.68, p = 0.09] for ESI; 0.54 (95% CI: 0.44 to 0.64, p = 0.42 for ESII; 0.57 (95% CI: 0.47 to 0.67, p = 0.16 for AS; 0.48 (95% IC: 0.38 to 0.57, p = 0.68 for STS score; and 0.52 (95% CI: 0.42 to 0.62, p = 0.64 for GS. The Hosmer–Lemeshow test indicated acceptable calibration for all scores (p > 0.05. Conclusions: In this real world Brazilian registry, the surgical risk scores were inaccurate in predicting mortality after TAVI. Risk models specifically developed for TAVI are required.

    Full Text Available The use of modern surgical dressings to prevent wound complications and surgical site infection (SSI after minimally invasive total knee arthroplasty (MIS-TKA is lacking. In a prospective, randomized, controlled study, 240 patients were randomized to receive either AQUACEL Ag Surgical dressing (study group or a standard dressing (control group after MIS-TKA. The primary outcome was wound complication (SSI and blister. The secondary outcomes were wear time and number of dressing changes in the hospital and patient satisfaction (pain, comfort, and ease of use. In the intention-to-treat analysis, there was a significant reduction in the incidence of superficial SSI (0.8%, 95% CI∶ 0.00–2.48 in the study group compared to 8.3% (95% CI∶ 3.32–13.3 in the control group (p=0.01. There were no differences in blister and deep/organ-space SSIs between the two groups. Multivariate analysis revealed that AQUACEL Ag Surgical dressing was an independent risk factor for reduction of SSI (odds ratio: 0.07, 95% CI: 0.01–0.58, p=0.01. The study group had longer wear time (5.2±0.7 versus 1.7±0.4 days, p<0.0001 and lower number of dressing changes (1.0±0.2 versus 3.6±1.3 times, p<0.0001. Increased patient satisfaction (p<0.0001 was also noted in the study group. AQUACEL Ag Surgical dressing is an ideal dressing to provide wound care efficacy, patient satisfaction, reduction of SSI, and cost-effectiveness following MIS-TKA.

    Resection of left hemisphere (LH) tumors is often complicated by the risks of causing language dysfunction. Although neurosurgeons' concerns when operating on the presumed dominant hemisphere are well known, literature evaluating laterality as a predictive surgical parameter in glioblastoma (GB) patients is sparse. We evaluated whether tumor laterality correlated with surgical performance, functional outcome, and survival. All patients with GB treated at our institution between 2006 and 2016 were reviewed. Analysis comprised clinical characteristics, extent of resection (EOR), neurologic outcome, and survival in relation to tumor lateralization. Two hundred thirty-five patients were included. Right hemisphere (RH) tumors were larger and more frequently extended into the frontal lobe. Preoperatively, limb paresis was more frequent in RH, whereas language deficits were more frequent in LH tumors (P = 0.0009 and P < 0.0001, respectively). At 6 months after resection, LH patients presented lower Karnofsky Performance Status (KPS) score (P = 0.036). More patients with LH tumors experienced dysphasia (P < 0.0001), and no difference was seen for paresis. Average EOR was comparable, but complete resection was achieved less often in LH tumors (37.7 vs. 64.8%; P = 0.0028). Although overall survival did not differ between groups, progression-free survival was shorter in LH tumors (7.4 vs. 10.1 months; P = 0.0225). Patients with LH tumors had a pronounced KPS score decline and shorter progression-free survival without effects on overall survival. This observation might partially be attributed to a more conservative surgical resection. Further investigation is needed to assess whether systematic use of awake surgery and intraoperative mapping results in increased EOR and improved quality survival of patients with GB.

    We assessed the value of (18)F-FDG uptake in the gallbladder polyp (GP) in risk stratification for surgical intervention and the optimal cutoff level of the parameters derived from GP (18)F-FDG uptake for differentiating malignant from benign etiologies in a select, homogeneous group of patients with 1- to 2-cm GPs. Fifty patients with 1- to 2-cm GPs incidentally found on the CT portion of PET/CT were retrospectively analyzed. All patients had histologic diagnoses. GP (18)F-FDG activity was visually scored positive (≥liver) or negative (L ratio) were also measured. Univariate and multivariate logistic regression analyses were performed to determine the utility of patient and clinical variables--that is, sex, age, gallstone, polyp size, and three (18)F-FDG-related parameters in risk stratification. Twenty GPs were classified as malignant and 30 as benign. Multivariate analyses showed that the age and all parameters (visual criteria, SUVgp, and GP/L) related to (18)F-FDG uptake were significant risk factors, with the GP/L being the most significant. The sex, size of GPs, and presence of concurrent gallstones were found to be insignificant. (18)F-FDG uptake in a GP is a strong risk factor that can be used to determine the necessity of surgical intervention more effectively than other known risk factors. However, all criteria derived from (18)F-FDG uptake presented in this series may be applicable to the assessment of 1- to 2-cm GPs.

    Full Text Available Surgical site infection (SSI has not been extensively studied in musculoskeletal tumors (MST owing to the rarity of the disease. We analyzed incidence and risk factors of SSI in MST. SSI incidence was evaluated in consecutive 457 MST cases (benign, 310 cases and malignant, 147 cases treated at our institution. A detailed analysis of the clinical background of the patients, pre- and postoperative hematological data, and other factors that might be associated with SSI incidence was performed for malignant MST cases. SSI occurred in 0.32% and 12.2% of benign and malignant MST cases, respectively. The duration of the surgery (P=0.0002 and intraoperative blood loss (P=0.0005 was significantly more in the SSI group than in the non-SSI group. We established the musculoskeletal oncological surgery invasiveness (MOSI index by combining 4 risk factors (blood loss, operation duration, preoperative chemotherapy, and the use of artificial materials. The MOSI index (0–4 points score significantly correlated with the risk of SSI, as demonstrated by an SSI incidence of 38.5% in the group with a high score (3-4 points. The MOSI index score and laboratory data at 1 week after surgery could facilitate risk evaluation and prompt diagnosis of SSI.

    This study compares the medium-term results of De Vega, modified De Vega, and ring annuloplasty techniques for the correction of tricuspid insufficiency and investigates the risk factors for recurrent grades 3 and 4 tricuspid insufficiency after repair. In our clinic, 93 patients with functional tricuspid insufficiency underwent surgical tricuspid repair from May 2007 through October 2010. The study was retrospective, and all the data pertaining to the patients were retrieved from hospital records. Functional capacity, recurrent tricuspid insufficiency, and risk factors aggravating the insufficiency were analyzed for each patient. In the medium term (25.4 ± 10.3 mo), the rates of grades 3 and 4 tricuspid insufficiency in the De Vega, modified De Vega, and ring annuloplasty groups were 31%, 23.1%, and 6.1%, respectively. Logistic regression analysis revealed that chronic obstructive pulmonary disease, left ventricular dysfunction (ejection fraction, tricuspid insufficiency. Medium-term survival was 90.6% for the De Vega group, 96.3% for the modified De Vega group, and 97.1% for the ring annuloplasty group. Ring annuloplasty provided the best relief from recurrent tricuspid insufficiency when compared with DeVega annuloplasty. Modified De Vega annuloplasty might be a suitable alternative to ring annuloplasty when rings are not available.

    To assess the Physiological and Operative Severity Score for the enumeration of mortality and morbidity (POSSUM) and its validity for use in gynaecological oncology surgery. All patients undergoing gynaecological oncology surgery at the Northern Gynaecological Oncology Centre (NGOC) Gateshead, UK over a period of 12months (2002-2003) were assessed prospectively. Mortality and morbidity predictions using the Portsmouth modification of the POSSUM algorithm (P-POSSUM) were compared to the actual outcomes. Performance of the model was also evaluated using the Hosmer and Lemeshow Chi square statistic (testing the goodness of fit). During this period 468 patients were assessed. The P-POSSUM appeared to over predict mortality rates for our patients. It predicted a 7% mortality rate for our patients compared to an observed rate of 2% (35 predicted deaths in comparison to 10 observed deaths), a difference that was statistically significant (H&L chi(2)=542.9, d.f. 8, prisk of mortality for gynaecological oncology patients undergoing surgery. The P-POSSUM algorithm will require further adjustments prior to adoption for gynaecological cancer surgery as a risk adjusted surgical audit tool.

    Colorectal surgery is commonly performed for colorectal cancer and other pathology such as diverticular and inflammatory bowel disease. Despite significant advances, such as laparoscopic techniques and multidisciplinary recovery programs, morbidity and mortality remain high and vary among surgical centers. The use of scoring systems and assessment of functional capacity may help in identifying high-risk patients and predicting complications. An understanding of perioperative factors affecting colon blood flow and oxygenation, suppression of stress response, optimal fluid therapy, and multimodal pain management are essential. These fundamental principles are more important than any specific choice of anesthetic agents. Anesthesiologists can significantly contribute to enhance recovery and improve the quality of perioperative care.

    In cases of penetrating injury with implantation of small arms ammunition, it can often be difficult to tell the difference between simple ballistics and ballistics associated with unexploded ordnances (UXOs). In the operative environment, where highly flammable substances are often close to the surgical site, detonation of UXOs could have catastrophic consequences for both the patient and surgical team. There is a paucity of information in the literature regarding how to evaluate whether an implanted munition contains explosive material. This report describes a patient who presented during Operation Enduring Freedom with an implanted munition suspicious for a UXO and the subsequent workup organized by Explosive Ordnance Disposal (EOD) Company prior to surgical removal. Clinical risk factors for UXOs include assassination attempts and/or wartime settings. Specific radiological features suggestive of a UXO include projectile size greater than 7.62-mm caliber, alterations in density of the tip, as well as radiological evidence of a hollowed-out core. If an implanted UXO is suspected, risks to the surgical and anesthesia teams can be minimized by notifying the nearest military installation with EOD capabilities and following clinical practice guidelines set forth by the Joint Theater Trauma System.

    Drug-resistant tuberculosis transmission in hospitals threatens staff and patient health. Surgical face masks used by patients with tuberculosis (TB) are believed to reduce transmission but have not been rigorously tested. We sought to quantify the efficacy of surgical face masks when worn by patients with multidrug-resistant TB (MDR-TB). Over 3 months, 17 patients with pulmonary MDR-TB occupied an MDR-TB ward in South Africa and wore face masks on alternate days. Ward air was exhausted to two identical chambers, each housing 90 pathogen-free guinea pigs that breathed ward air either when patients wore surgical face masks (intervention group) or when patients did not wear masks (control group). Efficacy was based on differences in guinea pig infections in each chamber. Sixty-nine of 90 control guinea pigs (76.6%; 95% confidence interval [CI], 68-85%) became infected, compared with 36 of 90 intervention guinea pigs (40%; 95% CI, 31-51%), representing a 56% (95% CI, 33-70.5%) decreased risk of TB transmission when patients used masks. Surgical face masks on patients with MDR-TB significantly reduced transmission and offer an adjunct measure for reducing TB transmission from infectious patients.

    Diagnostic molecular testing is used in the workup of thyroid nodules. While these tests appear to be promising in more definitively assigning a risk of malignancy, their effect on surgical decision making has yet to be demonstrated. To investigate the effect of diagnostic molecular profiling of thyroid nodules on the surgical decision-making process. A surgical management algorithm was developed and published after peer review that incorporated individual Bethesda System for Reporting Thyroid Cytopathology classifications with clinical, laboratory, and radiological results. This algorithm was created to formalize the decision-making process selected herein in managing patients with thyroid nodules. Between April 1, 2014, and March 31, 2015, a prospective study of patients who had undergone diagnostic molecular testing of a thyroid nodule before being seen for surgical consultation was performed. The recommended management undertaken by the surgeon was then prospectively compared with the corresponding one in the algorithm. Patients with thyroid nodules who did not undergo molecular testing and were seen for surgical consultation during the same period served as a control group. All pertinent treatment options were presented to each patient, and any deviation from the algorithm was recorded prospectively. To evaluate the appropriateness of any change (deviation) in management, the surgical histopathology diagnosis was correlated with the surgery performed. The study cohort comprised 140 patients who underwent molecular testing. Their mean (SD) age was 50.3 (14.6) years, and 75.0% (105 of 140) were female. Over a 1-year period, 20.3% (140 of 688) had undergone diagnostic molecular testing before surgical consultation, and 79.7% (548 of 688) had not undergone molecular testing. The surgical management deviated from the treatment algorithm in 12.9% (18 of 140) with molecular testing and in 10.2% (56 of 548) without molecular testing (P = .37). In the group with

    To identify incidence and risk factors for surgical glove perforation in small animal surgery. Observational cohort study. Surgical gloves (n = 2132) worn in 363 surgical procedures. All gloves worn by operative personnel were assessed for perforation at end-procedure using a water leak test. Putative risk factors were recorded by a surgical team member. Associations between risk factors and perforation were assessed using multivariable multi-level random-effects logistic regression models to control for hierarchical data structure. At least 1 glove perforation occurred in 26.2% of procedures. Identified risk factors for glove perforation included increased surgical duration (surgery >1 hour OR = 1.79, 95% CI = 1.12-2.86), performing orthopedic procedures (OR = 1.88; 95% CI = 1.23-2.88), any procedure using powered instruments (OR = 1.93; 95% CI = 1.21-3.09) or surgical wire (OR = 3.02; 95% CI = 1.50-6.05), use of polyisoprene as a glove material (OR = 1.59, 95% CI = 1.05-2.39), and operative role as primary surgeon (OR = 2.01; 95% CI = 1.35-2.98). The ability of the wearer to detect perforations intraoperatively was poor, with a sensitivity of 30.8%. There is a high incidence of unrecognized glove perforations in small animal surgery. © Copyright 2014 by The American College of Veterinary Surgeons.

    Full Text Available As technology and medications have improved and increased, survival rates are also increasing in intensive care units (ICUs, so it is now important to focus on improving the patient outcomes and recovery. To do this, ICU patients need to be assessed and started on an early mobility program, if stable. While the early mobilization of the ICU patients is not without risk, the current literature has demonstrated that patients can be safely and feasibly mobilized, even while requiring mechanical ventilation. These patients are at a high risk for muscle deconditioning due to limited mobility from numerous monitoring equipment and multiple medical conditions. Frequently, a critically ill patient only receives movement from nurses; such as, being turned side to side, pulled up in bed, or transferred from bed to a stretcher for a test. The implementation of an early mobility protocol that can be used by critical care nurses is important for positive patient outcomes minimizing the functional decline due to an ICU stay. This paper describes a pilot study to evaluate an early mobilization protocol to test the safety and feasibility for mechanically ventilated patients in a surgical trauma ICU in conjunction with the current unit standards.

    Full Text Available Introduction: The risk of postoperative hemorrhage from oral surgical procedures has been a concern in the treatment of patients who are receiving long-term anticoagulation therapy. A study undertaken in our institution to address questions about the amount and severity of bleeding associated with minor outpatient oral surgery procedures by assessing bleeding in patients who did not alter their anticoagulant regimen. Subjects and Methods: Eighty-three patients receiving long-term anticoagulant therapy visited Department of Oral and Maxillofacial Surgery from May 2010 to October 2011 for extractions and minor oral surgical procedures. Each patient was required to undergo preoperative assessment of prothrombin time (PT and measurement of the international normalized ratio. Fifty-six patients with preoperative PT values within the therapeutic range 3-4 were included in the study. The patients′ age ranged between 30 and 75 years. Application of surgispon was done following the procedure. Extraction of teeth performed with minimal trauma to the surrounding tissues, the socket margins sutured, and sutures removed after 5 days. Results: There was no significant incidence of prolonged or excessive hemorrhage and wound infection and the healing process was normal.

    Background Surgical patients frequently experience postoperative increases in creatinine levels. The authors hypothesized that even small increases in postoperative creatinine levels are associated with adverse outcomes. Methods The authors examined the association of postoperative changes from preoperative baseline creatinine with all-cause in-hospital mortality and hospital length of stay (HLOS) in a retrospective analysis of surgical patients at a single tertiary care center between January 2006 and June 2012. Results The data of 39,369 surgical patients (noncardiac surgery n = 37,345; cardiac surgery n = 2,024) were analyzed. Acute kidney injury (AKI)—by definition of the Kidney Disease: Improving Global Outcome group—was associated with a five-fold higher mortality (odds ratio [OR], 4.8; 95% CI, 4.1 to 5.7; P creatinine, exposure to radiocontrast agent, type of surgery, and surgical AKI risk factors. Importantly, even minor creatinine increases (Δcreatinine 25 to 49% above baseline but creatinine increases had a five-fold risk of death (OR, 5.4; 95% CI, 1.5 to 20.3; P creatinine levels are associated with adverse outcomes. These results emphasize the importance to find effective therapeutic approaches to prevent or treat even mild forms of postoperative kidney dysfunction to improve surgical outcomes. PMID:26492475

    Patients frequently have misconceptions regarding diagnosis, surgical indication, and expected outcome following spinal surgery for degenerative spinal disease. In this study, we sought to understand the relationship between patient-perceived surgical indications and patient expectations. We hypothesized that patients reporting appendicular symptoms as a primary surgical indication would report a higher rate of having expectations met by surgery compared to those patients reporting axial symptoms as a primary indication. Questionnaires were administered to patients who had undergone surgery for degenerative spinal disease at 2 tertiary care institutions. Questions assessed perception of the primary indication for undergoing surgery (radicular versus axial), whether the primary symptom improved after surgery, and whether patient expectations were met with surgery. Outcomes of interest included patient-reported symptomatic improvement following surgery and expectations met by surgery. Various factors were assessed for their relationship to these outcomes of interest. There were 151 unique survey respondents. Respondents were nearly split between having a patient-perceived indication for surgery as appendicular symptoms (55.6%) and axial symptoms (44.4%). Patient-perceived surgical indication being appendicular symptoms was the only factor predictive of patient-reported symptomatic improvement in our logistic regression model (OR 2.614; 95% CI 1.218-5.611). Patient-perceived surgical indication being appendicular symptoms (OR 3.300; 95% CI 1.575-6.944) and patient-reported symptomatic improvement (OR 33.297; 95% CI 12.186-90.979) were predictive of patients reporting their expectations met with surgery in both univariate and multivariate logistic regression modeling. We found that patient-reported appendicular symptoms as the primary indication for surgery were associated with a higher rate of both subjective improvement following surgery and having expectations met

    Seniors presenting with surgical disease face increased risk of postoperative morbidity and mortality and have increased treatment costs. Comprehensive Geriatric Assessment (CGA) is proposed to reduce morbidity, mortality, and the cost after surgery. A systematic review of CGA in emergency surgical patients was conducted. The primary outcome was cost-effectiveness; secondary outcomes were length of stay, return of function, and mortality. Inclusion and exclusion criteria were predefined. Systematic searches of MEDLINE, Embase, Cochrane, and National Health Service Economic Evaluation Database were performed. Text screening, bias assessment, and data extraction were performed by two authors. There were 560 articles identified; abstract review excluded 499 articles and full-text review excluded 53 articles. Eight studies were included; one nonorthopedic trauma and seven orthopedic trauma studies. Bias assessment revealed moderate to high risk of bias for all studies. Economic evaluation assessment identified two high-quality studies and six moderate or low quality studies. Pooled analysis from four studies assessed loss of function; loss of function decreased in the experimental arm (odds ratio 0.92, 95% confidence interval [CI]: 0.88-0.97). Pooled results for length of stay from five studies found a significant decrease (mean difference: -1.17, 95% CI: -1.63 to -0.71) after excluding the nonorthopedic trauma study. Pooled mortality was significantly decreased in seven studies (risk ratio: 0.78, 95% CI: 0.67-0.90). All studies decreased cost and improved health outcomes in a cost-effective manner. CGA improved return of function and mortality with reduced cost or improved utility. Our review suggests that CGA is economically dominant and the most cost-effective care model for orthogeriatric patients. Further research should examine other surgical fields.

    The acute abdomen (AA) still remains a challenging situation for surgeons. New pathological conditions have been imposed to our attention in this field in recent years. The definition of abdominal compartmental syndrome (ACS) in surgical practice and the introduction of new biological matrices, with the concepts of tension-free (TS) repair of incisional hernias, prompted us to set up new therapeutic strategies for the treatment of patients with AA. Thus we reviewed the cases of AA that we observed in recent years in which we performed a laparostomy in order to prevent or to treat an ACS. They are all cases of acute abdomen (AA), but from different origin, including chronic diseases, as in the course of inflammatory bowel disease (IBD), and acute pancreatitis. In all the cases, the open abdominal cavity was covered with a polyethylene sheet. The edges of the wound were sutured to the plastic sheet, and a traction exerted by a device that causes a negative pressure was added. This method was adopted in several cases without randomization, and resulted in excellent patient's outcomes. Abdominal compartmental syndrome, Acute abdomen, Laparostomy.

    Children with hydrocephalus are at risk for epilepsy both due to their underlying condition and as a consequence of surgical treatment; however, the relative contributions of these factors remain unknown. The authors sought to characterize epilepsy among children with infancy-onset hydrocephalus and to examine the risks of epilepsy associated with hydrocephalus subtype and with factors related to surgical treatment. We conducted a longitudinal cohort study of all children with infancy-onset hydrocephalus treated at a major regional children's hospital during 2002 to 2012, with follow-up to ascertain risk factors and epilepsy outcome through April 2015. Poisson regression was used to calculate adjusted risk ratios and 95% confidence intervals for associations. Among 379 children with hydrocephalus, 86 (23%) developed epilepsy (mean onset age = 2.7 years), almost one fifth of whom had a history of infantile spasms. Relative to spina bifida-associated hydrocephalus, children with other major hydrocephalus subtypes had fourfold higher risks of developing epilepsy. Among children who underwent surgery, surgical infection doubled the risk of epilepsy (risk ratio = 2.0, 95% confidence interval = 1.4 to 3.0). Epilepsy was associated with surgical failure for intracranial reasons but not extracranial reasons (risk ratio = 1.7, 95% confidence interval = 1.1 to 2.7; risk ratio = 1.1, 95% confidence interval = 0.7 to 1.9, respectively). Epilepsy is common among children with hydrocephalus. Compared with children with spina bifida-associated hydrocephalus, children with other major hydrocephalus subtypes have a markedly increased risk of epilepsy.

    To determine the association (1) between shorter operative duration and surgical site infection (SSI) and (2) between surgeon median operative duration and SSI risk among first-time hip and knee arthroplasties. Retrospective cohort study A total of 43 community hospitals located in the southeastern United States. Adults who developed SSIs according to National Healthcare Safety Network criteria within 365 days of first-time knee or hip arthroplasties performed between January 1, 2008 and December 31, 2012. Log-binomial regression models estimated the association (1) between operative duration and SSI outcome and (2) between surgeon median operative duration and SSI outcome. Hip and knee arthroplasties were evaluated in separate models. Each model was adjusted for American Society of Anesthesiology score and patient age. A total of 25,531 hip arthroplasties and 42,187 knee arthroplasties were included in the study. The risk of SSI in knee arthroplasties with an operative duration shorter than the 25th percentile was 0.40 times the risk of SSI in knee arthroplasties with an operative duration between the 25th and 75th percentile (risk ratio [RR], 0.40; 95% confidence interval [CI], 0.38-0.56; Poperative duration did not demonstrate significant association with SSI for hip arthroplasties (RR, 1.04; 95% CI, 0.79-1.37; P=.36). Knee arthroplasty surgeons with shorter median operative durations had a lower risk of SSI than surgeons with typical median operative durations (RR, 0.52; 95% CI, 0.43-0.64; Poperative durations were not associated with a higher SSI risk for knee or hip arthroplasty procedures in our analysis.

    We sought to determine whether publication of blood conservation guidelines by the Society of Thoracic Surgeons in 2007 influenced transfusion rates and to understand how patient- and hospital-level factors influenced blood product usage. We identified 4,465,016 patients in the Nationwide Inpatient Sample database who underwent cardiac operations between 1999 and 2010 (3,202,404 before the guidelines and 1,262,612 after). Hierarchical linear modeling was used to account for hospital- and patient-level clustering. Transfusion rates of blood products increased from 13% in 1999 to a peak of 34% in 2010. Use of all blood components increased over the study period. Aortic aneurysm repair had the highest transfusion rate with 54% of patients receiving products in 2010. In coronary artery bypass grafting, the number of patients receiving blood products increased from 12% in 1999 to 32% in 2010. Patients undergoing valvular operations had a transfusion rate of 15% in 1999, increasing to 36% in 2010. Patients undergoing combined operations had an increase from 13% to 40% over 11 years. Risk factors for transfusion were anemia (odds ratio [OR], 2.05; 95% confidence interval [CI], 2.01-2.09), coagulopathy (OR, 1.54; 95% CI, 1.51-1.57), diabetes (OR, 1.32; 95% CI, 1.28-1.36), renal failure (OR, 1.29; 95% CI, 1.26-1.32), and liver disease (OR, 1.23; 95% CI, 1.16-1.31). Compared to the Northeast, the risk for transfusion was significantly lower in the Midwest; higher-volume hospitals used fewer blood products than lower-volume centers. Cell salvage usage remained below 5% across all years. Independent of patient- and hospital-level factors, blood product utilization continues to increase for all cardiac operations despite publication of blood conservation guidelines in 2007. © 2014 AABB.

Methods A retrospective study of SSI was conducted in 242 HIV-infected patients including 17 patients who combined with hemophilia from October 2008 to September 2011 in Shanghai Public Health Clinical Center. SSI were classified according to Centers for Disease Control and Prevention (CDC criteria and identified by bedside surveillance and post-discharge follow-up. Data were analyzed using SPSS 16.0 statistical software (SPSS Inc., Chicago, IL. Results The SSI incidence rate was 47.5% (115 of 242; 38.4% incisional SSIs, 5.4% deep incisional SSIs and 3.7% organ/space SSIs. The SSI incidence rate was 37.9% in HIV-infected patients undergoing abdominal operation. Patients undergoing abdominal surgery with lower preoperative CD4 counts were more likely to develop SSIs. The incidence increased from 2.6% in clean wounds to 100% in dirty wounds. In the HIV-infected patients combined with hemophilia, the mean preoperative albumin and postoperative hemoglobin were found significantly lower than those in no-SSIs group (P Conclusions SSI is frequent in HIV-infected patients. And suitable perioperative management may decrease the SSIs incidence rate of HIV-infected patients.

    Full Text Available Abstract Background Surgical site infections (SSI are one of the most common healthcare associated infections in the low-middle income countries. Data on incidence and risk factors for SSI following surgeries in general and Obstetric and Gynecological surgeries in particular are scare. This study set out to identify risk factors for SSI in patients undergoing Obstetric and Gynecological surgeries in an Indian rural hospital. Methods Patients who underwent a surgical procedure between September 2010 to February 2013 in the 60-bedded ward of Obstetric and Gynecology department were included. Surveillance for SSI was based on the Centre for Disease Control (CDC definition and methodology. Incidence and risk factors for SSI, including those for specific procedure, were calculated from data collected on daily ward rounds. Results A total of 1173 patients underwent a surgical procedure during the study period. The incidence of SSI in the cohort was 7.84% (95% CI 6.30–9.38. Majority of SSI were superficial. Obstetric surgeries had a lower SSI incidence compared to gynecological surgeries (1.2% versus 10.3% respectively. The risk factors for SSI identified in the multivariate logistic regression model were age (OR 1.03, vaginal examination (OR 1.31; presence of vaginal discharge (OR 4.04; medical disease (OR 5.76; American Society of Anesthesia score greater than 3 (OR 12.8; concurrent surgical procedure (OR 3.26; each increase in hour of surgery, after the first hour, doubled the risk of SSI; inappropriate antibiotic prophylaxis increased the risk of SSI by nearly 5 times. Each day increase in stay in the hospital after the surgery increased the risk of contacting an SSI by 5%. Conclusions Incidence and risk factors from prospective SSI surveillance can be reported simultaneously for the Obstetric and Gynecological surgeries and can be part of routine practice in resource-constrained settings. The incidence of SSI was lower for Obstetric surgeries

    There are few data concerning the impact of preoperative renal function, assessed using estimated glomerular filtration rate, on surgical outcomes following acute type A aortic dissection. We investigated the accuracy of estimated glomerular filtration rate (in ml/min/1.73 m(2)) in predicting in-hospital mortality and postoperative renal replacement therapy in such cases. We reviewed 114 consecutive patients with non-dialysis-dependent renal dysfunction who underwent thoracic aortic surgery for acute type A aortic dissection between 1997 and 2012. Preoperative renal function was categorized as normal (estimated glomerular filtration rate >90; n = 15) or as mild (60-89; n = 39), moderate I (45-59; n = 39), moderate II (30-44; n = 14) or severe (15-29; n = 7) renal dysfunction. In-hospital mortality was 14.9%. Eighteen (15.8%) of 114 patients required renal replacement therapy. A more severe stage stratified by preoperative estimated glomerular filtration rate levels could effectively predict postoperative renal replacement therapy (area under the receiver operating characteristic curve 0.786). The best cut-off value of estimated glomerular filtration rate for predicting postoperative renal replacement therapy was 60 (sensitivity 95%, specificity 59%). On multiple regression analysis, the independent preoperative and intraoperative risk factors for postoperative renal replacement therapy were estimated glomerular filtration rate (P replacement (P replacement therapy (OR, 5.47; P regression analysis. Preoperative estimated glomerular filtration rate can effectively predict the need for renal replacement therapy after surgery for acute type A aortic dissection. However, it is not an effective diagnostic tool to predict in-hospital mortality. The complexity of the characteristics of patients who undergo surgical procedures may make prediction of surgical outcomes difficult. Risk models to predict hospital mortality and morbidities are needed to assist clinicians in

    This study aimed to quantitatively summarize the risk factors associated with surgical site infection after open reduction and internal fixation of tibial plateau fracture. Medline, Embase, CNKI, Wanfang database and Cochrane central database were searched for relevant original studies from database inception to October 2016. Eligible studies had to meet quality assessment criteria according to the Newcastle-Ottawa Scale, and had to evaluate the risk factors for surgical site infection after open reduction and internal fixation of tibial plateau fracture. Stata 11.0 software was used for this meta-analysis. Eight studies involving 2214 cases of tibial plateau fracture treated by open reduction and internal fixation and 219 cases of surgical site infection were included in this meta-analysis. The following parameters were identified as significant risk factors for surgical site infection after open reduction and internal fixation of tibial plateau fracture (p operative time (OR 2.15; 95% CI 1.53-3.02), tobacco use (OR 2.13; 95% CI 1.13-3.99), and external fixation (OR 2.07; 95% CI 1.05-4.09). Other factors, including male sex, were not identified as risk factors for surgical site infection. Patients with the abovementioned medical conditions are at risk of surgical site infection after open reduction and internal fixation of tibial plateau fracture. Surgeons should be cognizant of these risks and give relevant preoperative advice. Copyright © 2017. Published by Elsevier Ltd.

    Outcomes for oesophagogastric cancer surgery are compared with the aim of benchmarking quality of care. Adjusting for patient characteristics is crucial to avoid biased comparisons between providers. The study objective was to develop a case-mix adjustment model for comparing 30- and 90-day mortality and anastomotic leakage rates after oesophagogastric cancer resections. The study reviewed existing models, considered expert opinion and examined audit data in order to select predictors that were consequently used to develop a case-mix adjustment model for the National Oesophago-Gastric Cancer Audit, covering England and Wales. Models were developed on patients undergoing surgical resection between April 2011 and March 2013 using logistic regression. Model calibration and discrimination was quantified using a bootstrap procedure. Most existing risk models for oesophagogastric resections were methodologically weak, outdated or based on detailed laboratory data that are not generally available. In 4882 patients with oesophagogastric cancer used for model development, 30- and 90-day mortality rates were 2·3 and 4·4 per cent respectively, and 6·2 per cent of patients developed an anastomotic leak. The internally validated models, based on predictors selected from the literature, showed moderate discrimination (area under the receiver operating characteristic (ROC) curve 0·646 for 30-day mortality, 0·664 for 90-day mortality and 0·587 for anastomotic leakage) and good calibration. Based on available data, three case-mix adjustment models for postoperative outcomes in patients undergoing curative surgery for oesophagogastric cancer were developed. These models should be used for risk adjustment when assessing hospital performance in the National Health Service, and tested in other large health systems. © 2015 BJS Society Ltd Published by John Wiley & Sons Ltd.

    Full Text Available Background: Since the introduction of nerve-sparing radical prostatectomy (NSRP, there have been concerns about the increased risks of positive surgical margins (PSM and biochemical progression (BP. We examined the relationship of NSRP with PSM and BP using a large, mature dataset. Materials and Methods: Patients who underwent RP for clinically localized prostate cancer at our center between 1997 and 2008 were identified. Patients who received neoadjuvant therapy were excluded. We examined the relation of NSRP to the rate of PSM and BP in univariate and multivariate analyses adjusting for clinical and pathological variables including age, pretreatment prostate-specific antigen (PSA levels and doubling time, and pathological stage and grade. Results: In total, 856 patients were included, 70.9% underwent NSRP and 29.1% had non-NSRP. PSM rates were 13.5% in the NSRP group compared to 17.7% in non-NSRP (P=0.11. In a multivariate analysis, non-NSRP was preformed in patients with a higher pathological stage (HR 1.95, 95% CI 1.25-3.04, P=0.003 and a higher baseline PSA level (HR 1.04, 95% CI 1.01-1.08, P=0.005. With a median follow-up of 41 months, BP-free survival was 88% for non-NSRP compared to 92% for the NSRP group (log rank P=0.018; this difference was not significant in a multivariate Cox regression analysis (HR 0.54, 95% CI 0.28-1.06, P=0.09. Conclusion: When used in properly selected patients, NSRP does not seem to increase the risk of PSM and disease progression. The most effective way of resolving this issue is through a randomized clinical trial; however, such a trial is not feasible.

    Choosing between total hip replacement (THR) and partial hip replacement (PHR) for patients with intracapsular hip fractures is often based on subjective factors. Predicting the survival of these patients and risk of surgical re-intervention is essential to select the most adequate implant. We conducted a retrospective cohort study on mortality of patients over 70 years with intracapsular hip fractures who were treated between January 2010 and December 2013, with either PHR or THR. Patients' information was withdrawn from our local computerized database. The age-adjusted Charlson comorbidity index (ACCI) and American Society of Anesthesiologists (ASA) score were calculated for all patients. The patients were followed for 2 years after surgery. Survival and surgical re-intervention rates were compared between the two groups using a Multivariate Cox proportional hazard model. A total of 356 individuals were included in this study. At 2 years of follow-up, 221 (74.4%) of the patients with ACCI score≤7 were still alive, in contrast to only 20 (29.0%) of those with ACCI score>7. In addition, 201 (76.2%) of the patients with ASA score≤3 were still alive after 2 years, compared to 30 (32.6%) of individuals with ASA >3. Patients with the ACCI score>7, and ASA score>3 had a significant increase in all-cause 2-year mortality (adjusted hazard ratio of 3.2, 95% CI 2.2-4.6; and 3.12, 95% CI 2.2-4.5, respectively). Patients with an ASA score>3 had a quasi-significant increase in the re-intervention risk (adjusted hazard ratio 2.2, 95% CI 1.0-5.1). The sensitivity, specificity, positive predictive value and negative predictive values of ACCI in predicting 2-year mortality were 39.2%, 91.1%, 71%, and 74.4%, respectively. On the other hand, the sensitivity, specificity, positive predictive value and negative predictive values of ASA score in predicting 2-year mortality were 49.6%, 79.1%, 67.4%, and 76.1%, respectively. Both ACCI and ASA scales were able to predict the 2-year

    Radiological investigations have become a key adjunct in patient management and consequently radiation exposure to patients is increasing. The study objectives were to examine the use of radiological investigations in the management of acute surgical patients and to assess whether a guideline-based radiation exposure risk/benefit analysis can aid in the choice of radiological investigation used. A prospective observational study was completed over a 12-week period from April to July 2008 for all acute surgical admissions. Data recorded included demographics, clinical presentation, differential diagnosis, investigations, surgical interventions, and final clinical outcome. The use of radiological investigative modalities as an adjunct to clinical assessment was then evaluated against The Royal College of Radiologists (RCR) guidelines. A total of 380 acute surgical admissions (M = 174, F = 185, children = 21) were assessed during the study period. Seven hundred thirty-four radiological investigations were performed with a mean of 1.93 investigations per patient. Based on the RCR guidelines, 680 (92.6%) radiological investigations were warranted and included 142 CT scans (19.3%), 129 chest X-rays (17.6%), and 85 abdominal X-rays (11.6%). Clinically, radiological imaging complemented surgical management in 326 patients (85.8%) and the management plan remained unchanged for the remaining 54 patients (14.2%). This accounted for an average radiation dose of 4.18 millisievert (mSv) per patient or 626 days of background radiation exposure. CT imaging was responsible for the majority of the radiation exposure, with a total of 1310 mSv (82.6%) of the total radiation exposure being attributed to CT imaging in 20.8% of acute admissions. Subgroup analysis demonstrated that 92.8% of the CT scans performed were appropriate. Radiation exposure was generally low for the majority of acute surgical admissions. However, it is recommended that CT imaging requests be evaluated carefully

    Object of study: Improvement of life quality of patients with high stroke risk ia the main goal for development of system for patient-specific modeling of cardiovascular system. This work is dedicated at increase of safety outcomes for surgical treatment of brain blood supply alterations. The objects of study are common carotid artery, internal and external carotid arteries and bulb. Methods: We estimated mechanical properties of carotid arteries tissues and patching materials utilized at angioplasty. We studied angioarchitecture features of arteries. We developed and clinically adapted computer biomechanical models, which are characterized by geometrical, physical and mechanical similarity with carotid artery in norm and with pathology (atherosclerosis, pathological tortuosity, and their combination). Results: Collaboration of practicing cardiovascular surgeons and specialists in the area of Mathematics and Mechanics allowed to successfully conduct finite-element modeling of surgical treatment taking into account various features of operation techniques and patching materials for a specific patient. Numerical experiment allowed to reveal factors leading to brain blood supply decrease and atherosclerosis development. Modeling of carotid artery reconstruction surgery for a specific patient on the basis of the constructed biomechanical model demonstrated the possibility of its application in clinical practice at approximation of numerical experiment to the real conditions.

    Psychiatric outcomes of patients submitted to epilepsy surgery have gained particular interest given the high prevalence of pre-surgical psychiatric disorders (PD) in this population. The present study aimed to verify the possible pre-surgical predictors for psychiatric disorders following epilepsy surgery in a homogeneous series of patients with refractory temporal lobe epilepsy and mesial temporal sclerosis (TLE-MTS). Data from 115 TLE-MTS patients (65 females; 56.5%) who underwent cortico-amygdalohippocampectomy were included. Pre- and post-surgical psychiatric evaluations were performed using DSM-IV criteria. Pre-surgical PD - particularly mood, anxiety and psychotic disorders - were diagnosed in 47 patients (40.8%). Twenty-seven patients (54% of those with pre-surgical PD) demonstrated a remission of psychiatric symptoms on post-surgical psychiatric evaluation. Eleven patients (9.6%) developed de novo PD. The presence of pre-surgical depression (OR=3.32; p=0.008), pre-surgical interictal psychosis (OR=4.39; p=0.009) and epileptiform discharges contralateral to the epileptogenic zone (OR=2.73; p=0.01) were risk factors associated with post-surgical PD. Although epilepsy surgery is considered to be the best treatment option for patients with refractory TLE-MTS, the relatively high psychiatric comorbidities observed in surgical candidates and their possible negative impact on post-surgical outcomes require a careful pre-surgical evaluation of clinical, sociodemographic and psychiatric factors.

    Critically ill surgical patients are always at increased risk of actual or potentially life-threatening health complications. Central/peripheral venous lines form a key part of their care. We review the current evidence on incidence of central and peripheral venous catheter-related bloodstream infections in critically ill surgical patients, and outline pathways for prevention and intervention. An extensive systematic electronic search was carried out on the relevant databases. Articles were considered suitable for inclusion if they investigated catheter colonisation and catheter-related bloodstream infection. Two independent reviewers engaged in selecting the appropriate articles in line with our protocol retrieved 8 articles published from 1999 to 2011. Outcomes on CVC colonisation and infections were investigated in six studies; four of which were prospective cohort studies, one prospective longitudinal study and one retrospective cohort study. Outcomes relating only to PICCs were reported in one prospective randomised trial. We identified only one study that compared CVC- and PICC-related complications in surgical intensive care units. Although our search protocol may not have yielded an exhaustive list we have identified a key deficiency in the literature, namely a paucity of studies investigating the incidence of CVC- and PICC-related bloodstream infection in exclusively critically ill surgical populations. In summary, the diverse definitions for the diagnosis of central and peripheral venous catheter-related bloodstream infections along with the vastly different sample size and extremely small PICC population size has, predictably, yielded inconsistent findings. Our current understanding is still limited; the studies we have identified do point us towards some tentative understanding that the CVC/PICC performance remains inconclusive.

    Full Text Available Does the Finneson-Cooper score reflect the true value of predicting surgical success before discectomy? The aim of this study was to identify reliable predictors for surgical success two year after surgery for patients with LDH. Prospective analysis of 154 patients with LDH who underwent single-level lumbar discectomy was performed. Pre- and post-surgical success was assessed by the Oswestry Disability Index (ODI over a 2-year period. The Finneson-Cooper score also was used for evaluation of the clinical results. Using the ODI, surgical success was defined as a 30% (or more improvement on the ODI score from the baseline. The ODI was considered the gold standard in this study. Finally, the sensitivity, specificity, and positive and negative predictive power of the Finneson-Cooper score in predicting surgical success were calculated. The mean age of the patients was 49.6 (SD = 9.3 years and 47.4% were male. Significant improvement from the pre- to post-operative ODI scores was observed (P < 0.001. Post-surgical success was 76.0% (n = 117. The patients' rating on surgical success assessments by the ODI discriminated well between sub-groups of patients who differed with respect to the Finneson-Cooper score. Regarding patients' surgical success, the sensitivity, specificity, and accuracy of the Finneson-Cooper ratings correlated with success rate. The findings indicated that the Finneson-Cooper score was reflective of surgical success before discectomy.

In the late postoperative period, we detected the progression of limb ischemia in 4(5.5% patients; in connection with that, we performed limb amputation at thigh level. Ischemic stroke with a lethal outcome developed in one patient (1.4%. Conclusion: In patients with multifocal atherosclerosis, multilevel reconstructive surgical interventions must be performed in stages, due to the high operational risk, and risk of complications, secondary amputations and lethality in the postoperative period.

    The impact of operative technique on outcomes in laparoscopic sleeve gastrectomy has been explored previously; however, the relative importance of patient characteristics remains unknown. Our aim was to characterize national variability in operative technique for laparoscopic sleeve gastrectomy and determine whether patient-specific factors are more critical to predicting outcomes. We queried the database of the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program for laparoscopic sleeve gastrostomies performed in 2015 (n = 88,845). Logistic regression models were used to determine predictors of postoperative outcomes. In 2015, >460 variations of laparoscopic sleeve gastrectomy were performed based on combinations of bougie size, distance from the pylorus, use of staple line reinforcement, and oversewing of the staple line. Despite such substantial variability, technique variants were not predictive of outcomes, including perioperative morbidity, leak, or bleeding (all P ≥ .05). Instead, preoperative patient characteristics were found to be more predictive of these outcomes after laparoscopic sleeve gastrectomy. Only history of gastroesophageal disease (odds ratio 1.44, 95% confidence interval 1.08-1.91, P < .01) was associated with leak. Considerable variability exists in technique among surgeons nationally, but patient characteristics are more predictive of adverse outcomes after laparoscopic sleeve gastrectomy. Bundled payments and reimbursement policies should account for patient-specific factors in addition to current accreditation and volume thresholds when deciding risk-adjustment strategies.

    Identification of prognostic factors for surgery in patients with sciatica is important to be able to predict surgery in an early stage. Identification of prognostic factors predicting persistent pain, disability and recovery are important for better understanding of the clinical course, to inform patient and physician and support decision making. Consequently, we aimed to systematically review prognostic factors predicting outcome in non-surgically treated patients with sciatica. A search of Medline, Embase, Web of Science and Cinahl, up to March 2012 was performed for prospective cohort studies on prognostic factors for non-surgically treated sciatica. Two reviewers independently selected studies for inclusion and assessed the risk of bias. Outcomes were pain, disability, recovery and surgery. A best evidence synthesis was carried out in order to assess and summarize the data. The initial search yielded 4392 articles of which 23 articles reporting on 14 original cohorts met the inclusion criteria. High clinical, methodological and statistical heterogeneity among studies was found. Reported evidence regarding prognostic factors predicting the outcome in sciatica is limited. The majority of factors that have been evaluated, e.g., age, body mass index, smoking and sensory disturbance, showed no association with outcome. The only positive association with strong evidence was found for leg pain intensity at baseline as prognostic factor for subsequent surgery. © 2013 European Federation of International Association for the Study of Pain Chapters.

    The aim of the present study was to create a unique risk adjustment model for surgical site infection (SSI) in patients who underwent colorectal surgery (CRS) at the Cleveland Clinic (CC) with inherent high risk factors by using a nationwide database. The American College of Surgeons National Surgical Quality Improvement Program database was queried to identify patients who underwent CRS between 2005 and 2010. Initially, CC cases were identified from all NSQIP data according to case identifier and separated from the other NSQIP centers. Demographics, comorbidities, and outcomes were compared. Logistic regression analyses were used to assess the association between SSI and center-related factors. A total of 70,536 patients met the inclusion criteria and underwent CRS, 1090 patients (1.5%) at the CC and 69,446 patients (98.5%) at other centers. Male gender, work-relative value unit, diagnosis of inflammatory bowel disease, pouch formation, open surgery, steroid use, and preoperative radiotherapy rates were significantly higher in the CC cases. Overall morbidity and individual postoperative complication rates were found to be similar in the CC and other centers except for the following: organ-space SSI and sepsis rates (higher in the CC cases); and pneumonia and ventilator dependency rates (higher in the other centers). After covariate adjustment, the estimated degree of difference between the CC and other institutions with respect to organ-space SSI was reduced (OR 1.38, 95% CI 1.08-1.77). The unique risk adjustment strategy may provide center-specific comprehensive analysis, especially for hospitals that perform inherently high-risk procedures. Higher surgical complexity may be the reason for increased SSI rates in the NSQIP at tertiary care centers.

    Results of the radioisotope esophageal motility studies in patients after surgical treatment of achalasia are presented. 28 patients were studied. In both group of the patients (after Belsey-Mark and modified Nissen antireflux surgical techniques) slightly delayed esophageal transit time was found. Mean transit time of the esophagus proved to be a useful practical parameter. This simple, noninvasive, physiological radioisotope technique is recommended for follow-up studies of patients after gastroesophageal surgery. (N.T.). 10 refs., 2 figs

    Computer simulation methods for determining patient dose from dental radiography have demonstrated that patient risk from a two-film interproximal examination ranges from 1.1 X 10(-8) to 3.4 X 10(-7) using 90-kVp beams, depending on film speed, projection technique, and age and sex of the patient. Further, changing from a short-cone round-beam to a long-cone technique with rectangular collimation reduces risk by a factor of 2.9, independent of other factors

    BACKGROUND: Persistent acetabular dysplasia (AD) after periacetabular osteotomy has been hypothesized to increase the risk for malpositioning of the acetabular component. In this study, we investigate whether AD is an independent risk factor for cup malpositioning during primary total hip...... arthroplasty (THA). METHODS: Patient demographics, surgical approach, presence of AD assessed using the lateral center-edge angle, and acetabular cup positioning determined using Martell Hip Analysis Suite were investigated in 836 primary THA patients enrolled in a prospective multicenter study.

    Full Text Available Abstract Background Abdominal surgical site infections are among the most common complications of inpatient admissions and have serious consequences for outcomes and costs. Different risk factors may be involved, including age, sex, nutrition and immunity, prophylactic antibiotics, operation type and duration, type of shaving, and secondary infections. This study aimed to determine the risk factors affecting abdominal surgical site infections and their incidence at Imam Khomeini, a major referral teaching hospital in Iran. Methods Patients (n = 802 who had undergone abdominal surgery were studied and the relationships among variables were analyzed by Student's t and Chi-square tests. The subjects were followed for 30 days and by a 20-item questionnaire. Data were collected through pre- and post-operative examinations and telephone follow-ups. Results Of the 802 patients, 139 suffered from SSI (17.4%. In 40.8% of the cases, the wound was dirty infected. The average age for the patients was 46.7 years. The operations were elective in 75.7% of the cases and 24.7% were urgent. The average duration of the operation was 2.24 hours, the average duration of pre-operative hospital stay 4.31 days and the average length of (pre- and post-operation hospital stay 11.2 days. Three quarters of the cases were shaved 12 hours before the operation. The increased operation time, increased bed stay, electivity of the operation, septicity of the wound, type of incision, the administration of prophylactic antibiotic, type of operation, background disease, and the increased time lapse between shaving and operation all significantly associated with SSI with a p-value less than 0.001. Conclusion In view of the high rate of SSI reported here (17.4% compared with the 14% quoted in literature, this study suggests that by reducing the average operation time to less than 2 hours, the average preoperative stay to 4 days and the overall stay to less than 11 days, and

    Purpose: To compare perioperative and follow-up outcomes of symptomatic versus asymptomatic patients following endovascular repair of anastomotic pseudoaneurysms (APAs) of the abdominal aorta and iliac arteries. Methods: We retrospectively evaluated 17 patients (two women), with a mean age of 66.2 years (range 30–83 years). Endovascular treatment was performed in ten symptomatic, and seven asymptomatic patients electively. Data included technical success, perioperative (within 30 days) mortality and morbidity, as well as stent graft-related complications, reinterventions, and survival in follow-up. Results: Bifurcated (n = 13), aortomonoiliac (n = 3) endoprosthesis and one aortic cuff were implanted with a primary technical success rate of 100%. The overall in-hospital mortality and morbidity rate was 11.8% and 35.3%. The mean survival was 36.5 (range 0–111) months. There was a clear trend toward a lower overall survival within hospital and at one and three years for symptomatic patients compared to asymptomatic patients. (47.7 (CI: 0–138.8) versus 52.6 (CI: 28.5–76.8) months (p = 0.274)). During follow-up, late stent graft related complications were observed in six patients (35.3%) necessitating eight endovascular reinterventions. Additional three patients with primary fistulas between the APA and the intestine were treated by late surgical revision. Conclusion: Endovascular therapy of APAs represents a considerable alternative to open surgical repair. Short proximal anchoring zones still pose a risk for endoleaks and unintentional overstenting of side branches with commercially available devices, but this might be overcome by use of fenestrated and branched stent grafts in elective cases.

    The American College of Surgeons and the American Geriatrics Society have suggested that preoperative cognitive screening should be performed in older surgical patients. We hypothesized that unrecognized cognitive impairment in patients without a history of dementia is a risk factor for development of postoperative complications. We enrolled 211 patients 65 yr of age or older without a diagnosis of dementia who were scheduled for an elective hip or knee replacement. Patients were cognitively screened preoperatively using the Mini-Cog and demographic, medical, functional, and emotional/social data were gathered using standard instruments or review of the medical record. Outcomes included discharge to place other than home (primary outcome), delirium, in-hospital medical complications, hospital length-of-stay, 30-day emergency room visits, and mortality. Data were analyzed using univariate and multivariate analyses. Fifty of 211 (24%) patients screened positive for probable cognitive impairment (Mini-Cog less than or equal to 2). On age-adjusted multivariate analysis, patients with a Mini-Cog score less than or equal to 2 were more likely to be discharged to a place other than home (67% vs. 34%; odds ratio = 3.88, 95% CI = 1.58 to 9.55), develop postoperative delirium (21% vs. 7%; odds ratio = 4.52, 95% CI = 1.30 to 15.68), and have a longer hospital length of stay (hazard ratio = 0.63, 95% CI = 0.42 to 0.95) compared to those with a Mini-Cog score greater than 2. Many older elective orthopedic surgical patients have probable cognitive impairment preoperatively. Such impairment is associated with development of delirium postoperatively, a longer hospital stay, and lower likelihood of going home upon hospital discharge.

    First generation cephalosporins are commonly used as antibiotic prophylaxis prior to surgery. Patients labeled as penicillin-allergic are often precluded from receiving cephalosporins because of an allergic cross-reactivity. The aims of this study were to evaluate the clinical practice for surgical prophylaxis at Nationwide Children's Hospital and to determine the incidence of adverse effects and allergic reactions when using cephalosporins in patients labeled as penicillin-allergic. A retrospective chart review was performed to identify patients who were allergic to penicillin, penicillin antibiotic family, who required surgical treatment for an existing medical condition, and received an antibiotic to prevent surgical site infection. Five hundred thirteen penicillin-allergic patients were identified, encompassing 624 surgical cases. Cephalosporins were administered in 153 cases (24.5%) with cefazolin used 83% of the time. Only one documented case of nonanaphylactic reaction was reported. Clindamycin was the most common cephalosporin substitute (n=387), and the reported adverse reaction rate was 1.5%. No cases of anaphylaxis were documented. Our data suggest that the administration of cephalosporins for surgical prophylaxis following induction of anesthesia in a patient with a known or reported penicillin-allergy appears appropriate and results in a lower adverse event rate that when clindamycin is administered.

    Full Text Available Introduction: Causation of surgical site infection (SSI following craniotomy is multifactorial. Most preventive strategies (including site preparation and antibiotic prophylaxis revolve around reducing preoperative contamination of the local site. There is little evidence, however, linking site contamination with postoperative infections. This is important given the preference for performing non-shaved cranial surgery. We undertook a prospective study to document the scalp flora in neurosurgical patients in an Indian setting and to assess possible association with SSI. Materials and Methods: A prospective study recruited 45 patients undergoing non-shaved clean craniotomies for various brain tumors. Standard perioperative procedures and antibiotic policy were employed. Prior to and immediately following the pre-surgical scrubbing, we collected swabs and evaluated their growth qualitatively. SSI was documented adhering to CDC guidelines. The association of swab-positivity with various parameters (including SSI was evaluated. Results: Pre-scrub positivity was seen in 18 of 44 patients, three of them developed subsequent SSI. Most were known skin contaminants. Five patients had swab positivity after scrubbing, though none of these developed any SSI. Four of these five had pre-scrub positivity. In three the same organisms persisted (two being Staphylococcus aureus, and one had different growth post-scrub, whereas one patient developed new growth (contaminant mycelial fungus in the post-scrub swab. We did not find any association between swab positivity and SSI. Swab positivity was also not related to hair-length or hygiene. Conclusion: Scalp flora in Indian patients is similar to that described. Pre-surgical preparation does not always eliminate this contamination (especially staphylococcus. However, this does not necessarily translate into increased SSI. Moreover, the results also provide objective evidence to support the performance of non

Retrospective case control analysis of high-risk patients undergoing cardiac surgery. Single cardiac center. Sixty one adult cardiac surgical patients with pulmonary hypertension, 40 of whom received inhalation therapy. Inhaled milrinone and inhaled prostacyclin were administered before cardiopulmonary bypass (CPB). Administration of both inhaled prostacyclin and milrinone was associated with reductions in central venous pressure, and mean pulmonary artery pressure, increases in cardiac index, heart rate, and the mean arterial-to-mean pulmonary artery pressure ratio (p milrinone before CPB was associated with a reduction in the severity of pulmonary hypertension. In addition, a significant reduction in vasoactive support in the intensive care unit during the first 24 hours after cardiac surgery was observed. The impact of this strategy on postoperative survival needs to be determined. Copyright © 2014 Elsevier Inc. All rights reserved.

    To determine the prevalence of nutritional risk in surgical departments and to evaluate the impact of nutritional support on clinical outcomes. The nutritional risk in different surgical diseases and the different way of nutritional support on clinical outcomes in patients at nutritional risk remain unclear. Hospitalized patients from general surgical departments were screened using the Nutritional Risk Screening (NRS) 2002 questionnaire on admission. Data were collected on nutritional risk, complications, and length of stay (LOS). Overall, 5034 patients were recruited; the overall prevalence of nutritional risk on admission were 19.2%. The highest prevalence was found among patients with gastric cancer. At-risk patients had more complications and longer LOS than nonrisk patients. Of the at-risk patients, the complication rate was significantly lower and LOS was significantly shorter in the nutritional-support group than in the no-support group (20.9 versus 30.0%, P nutrition or who received support for 5 to 7 days, or daily support entailing 16 to 25 kcal/kg of nonprotein energy. Different surgical diseases have different levels of nutritional risk. The provision of nutritional support was associated with a lower complication rate and a shorter LOS for gastric, colorectal, and HPB cancer patients at nutritional risk. The improper use of nutritional support may not improve outcomes for at-risk patients. PMID:26011204

    To evaluate the demographics, surgical indications and clinical results of patients with repositioned or explanted intraocular lens (IOL) in a tertiary referral eye hospital. Forty-eight eyes of 48 patients that underwent surgery to exchange or reposition the IOL at Ulucanlar Eye Training and Research Hospital between 2009 and 2013 were included in the study. Medical records of patients were evaluated for surgical indications, time elapsed since initial operation, preoperative and postoperative best corrected distance visual acuity and the presence of ocular disease. The mean age of the 31 male and 17 female patients was 64.91±14.26 years. Median time between the initial and final operations was 36.0 months. Pseudoexfoliation syndrome (PEX) was present in 25% of the patients. There was history of previous vitreoretinal surgery in 18.8% of patients, ocular trauma in 6.3%, high myopia and refractive surgery in 4% of patients. In the first operation the IOL was implanted in the sulcus in 50%, in the bag in 27.1%, and in the anterior chamber in 20.8%; following the final surgery the IOL was in the sulcus in 27.1%, in the anterior chamber in 22.9%, and fixated to the sclera in 10.4% of the patients, while the remaining 29.1% remained aphakic. Indication for the secondary surgery was IOL dislocation in 58%, corneal decompensation in 20.8% and IOL degeneration in 6.3%. In the final surgery, IOL was exchanged in 54.2% of the cases, removed in 31.3% of cases, and repositioned in 14.6%. Visual acuity improved by 1-3 lines in 52.3% and remained stable in 13.6% of the patients postoperatively. IOL exchange may be necessary at any time following cataract surgery due to surgical complications, IOL dislocation, biometric measurement errors and corneal decompensation. Factors such as vitreoretinal surgery and the existence of PEX increase the risk of IOL exchange surgery.

    Dr Robert R. Shaw arrived in Dallas to practice Thoracic Surgery in 1937, as John Alexander's 7th Thoracic Surgical Resident from Michigan University Medical Center. Dr Shaw's modus operandi was, "You can accomplish almost anything, if you don't care who gets the credit." He was a remarkable individual who cared the most about the patient and very little about getting credit for himself. From 1937 to 1970, Dr Shaw established one of the largest lung cancer surgical centers in the world in Dallas, Texas. It was larger than M.D. Anderson and Memorial Sloan-Kettering Hospitals put together regarding the surgical treatment of lung cancer patients. To accomplish this, he had the help of Dr Donald L. Paulson, who trained at the Mayo Clinic and served as Chief of Thoracic Surgery at Brook Army Hospital during the Second World War. Following the War, because of his love for Texas, he ended up as a partner of Dr Shaw in Dallas. Together, they pursued the development of this very large surgical lung cancer center. Dr Shaw and his wife Ruth went to Afghanistan with Medico multiple times to teach men modern cardiac and thoracic surgery. They also served as consultants on Medico's Ship of Hope in Africa. Dr Shaw initiated multiple new operations including: 1) resection of Pancoast's cancer of the lung after preoperative irradiation; 2) upper lobe of the lung bronchoplasty, reattaching (and saving) the lower lobe to prevent the "disabling" pneumonectomy; and 3) resections of pulmonary mucoid impaction of the lung in asthmatics. Because of his humility and giving "the credit to others," Dr Shaw was never President of a major medical or surgical association. Copyright © 2012 The Society of Thoracic Surgeons.

    Full Text Available Background: Closure of a secundum atrial septal defect (ASD is possible through surgical intervention or device placement. During surgical intervention, concomitant pathologies are corrected. The present study was conducted to investigate the outcomes of surgical ASD closure, to determine the risk factors of mortality, and establish the effects of concomitant disease correction. Methods: Between October 1989 and October 2009, 693 adults underwent surgery for secundum ASD. Their mean age was 40.9±13.1 years, and 199 (28.7% were male. Preoperatively, atrial fibrillation was noted in 39 patients (5.6% and significant tricuspid regurgitation (TR in 137 patients (19.8%. The mean follow-up duration was 12.4±4.7 years. Results: There was no 30-day mortality. The 1-, 5-, 10-, and 20-year survival rates were 99.4%, 96.8%, 94.5%, and 81.6%, respectively. In multivariate analysis, significant preoperative TR (hazard ratio [HR], 1.95; 95% confidence interval [CI], 1.09 to 3.16; p=0.023 and preoperative age (HR, 1.04; 95% CI, 1.01 to 1.06; p=0.001 were independent risk factors for late mortality. The TR grade significantly decreased after ASD closure with tricuspid repair. However, in patients with more than mild TR, repair was not associated with improved long-term survival (p=0.518. Conclusion: Surgical ASD closure is safe. Significant preoperative TR and age showed a strong negative correlation with survival. Our data showed that tricuspid valve repair improved the TR grade effectively. However, no effect on long-term survival was found. Therefore, early surgery before the development of significant TR mat be beneficial for improving postoperative survival.

    Pre-/poststudy comparing surgical and nonsurgical treatment. To identify whether orthopedic spinal surgery can effectively improve life satisfaction and self-esteem in patients with adolescent idiopathic scoliosis. There have been many studies about the effect of spinal deformity and its various treatments on the mental health of patients with adolescent idiopathic scoliosis. Scoliosis has been reported to have a negative effect on the life quality and mental health of patients. It has also been reported that no matter what the treatment, the existence of scoliosis is a risk factor for depression. However, there has been no report on whether orthopedic spinal surgery affects the life satisfaction and self-esteem of scoliosis patients. Forty-six patients with Cobb angles of more than 30° were recruited from a group of patients that were treated from January 2007 to August 2007. Twenty-one patients with Cobb angles of more than 40° underwent surgical correction while the remaining patients received regular observation (n = 11) or bracing (n = 14). Self-esteem and life satisfaction were assessed before and approximately 1 year after treatment using previously validated scales. There were no between-group differences in age, sex, or major curve location between the surgically and nonsurgically treated groups. The major curve Cobb angle decreased significantly following treatment in the surgically treated (52° ± 10° to 15° ± 8°, P life satisfaction (8 ± 1 vs. 7 ± 10); however, preintervention self-esteem scores were significantly higher in the nonsurgically treated group (28 ± 4 vs. 25 ± 3, P = 0.008). Postintervention, both life satisfaction (9 ± 1) and self-esteem (31 ± 2) scores improved significantly (P Self-esteem levels decreased significantly in the nonsurgically treated group (P self-esteem and life satisfaction scores were significantly higher in the surgically treated than the nonsurgically treated group (P self-esteem and life satisfaction.

    Surgical therapy remains the gold standard treatment for Peyronie's Disease (PD). Surgical options include plication, grafting, and placement of inflatable penile prosthesis (IPP). Postoperative erectile dysfunction (ED) is a potential complication for PD surgery without IPP. We present our large series follow-up to evaluate preoperative risk factors for postoperative ED. The aim of this study is to evaluate preoperative risk factors for the development of ED following surgical correction of PD taking into account the degree of curvature, graft size, surgical approach, hypertension, hyperlipidemia, diabetes, smoking history, preoperative use of phosphodiesterase 5 inhibitors (PDE5), and preoperative duplex ultrasound findings including peak systolic and end diastolic velocities and resistive index. We identified 218 men undergoing either tunica albuginea plication (TAP) or partial plaque excision with pericardial grafting for PD following a previously published algorithm between November 1992 and April 2007. Preoperative and postoperative erectile function, curvature characteristics, presence of vascular risk factors, and duplex ultrasound findings were available on 109 patients. Our primary outcome measure is the development of ED after surgery for PD. Ten percent of TAP and 21% of plaque excision with grafting patients developed postoperative ED. Neither curve direction (P = 0.76), graft area (P = 0.78), surgical approach (P = 0.12), chronic hypertension (P = 0.51), hyperlipidemia (P = 0.87), diabetes (P = 0.69), nor smoking history (P = 0.99) were significant predictors of postoperative ED. No combination of risk factors was found to be predictive of postoperative ED. Preoperative use of PDE5 was not a significant predictor of postoperative ED (P = 0.33). Neither peak systolic, end diastolic, nor resistive index were significant predictors of ED (P = 0.28, 0.28, and 0.25, respectively). This long-term follow-up of a large published series suggests that neither

    Surgical paients have been known to benefit immensely from psychological interventions. This study set out to assess the pre and postoperative anxiety levels and depression and the effect of cognitive therapy among Nigerian surgical patients. The effects of gender and educational status on perioperative anxiety and depression were also evaluated. The study utilized a controlled outcome design to evaluate the efficacy of self-instructional training (SIT) and rational emotive therapy (RET) in surgical patients. Preoperative anxiety and depression scores were used as co-variants. Thirty-three (33) elective surgical patients were sampled randomly, divided into 3 groups of eleven (11) patients each. Eight (8) subjects underwent gynaecological procedures while the remaining 25 subjects had general surgical procedures. The mean age was 32.72 +/- 15.83 years (range = 17-16 years.) The major instruments used in the study were the State Anxiety Subscale of the Speilberger State Trait Anxiety Inventory (STAI) and Hospital Anxiety and Depression Inventory. SIT had the potential to reduce anxiety level among subjects postoperatively (t = 2.06; df = 10; p < 0.05). The use of RET reduced depression among surgical patients (t = 1.23; df = 10; p < 0.05). It was concluded that surgical patients manifest varying degrees of anxiety preoperatively and postoperatively. Patient's pre and postoperative anxiety and depression can be reduced by the introduction of SIT and RET.

    Full Text Available A 60-year-old male patient presented with complaints of persistent red to a brown-colored plaque on his scrotum, with duration of approximately three years. The patient had been treated with oral and topical antifungals for inguinal tinea for several months and after that with topical corticosteroids for eczema for several more months. None of the regimens achieved any therapeutic effect. The histopathological evaluation revealed the presence of atypical keratinocytes in all layers of the epidermis with the altered epidermal pattern, spread parabasal mitotic activity, without secondary satellites, multiple dyskeratotic cells and multinucleated cells. The diagnosis of an intraepithelial non-invasive squamous cell carcinoma, associated with koilocytic dysplasia and hyperplasia was made, meeting the criteria for Bowen disease. An elliptic surgical excision of the lesion was made, while the defect was closed with single stitches, with excellent therapeutic and aesthetic result. First described by John T. Bowen in 1912, Bowen disease (BD represents a squamous cell carcinoma (SCC in situ with the potential for significant lateral spread. Treatment options include the application of topical 5-flurorouracil cream – useful in non-hairy areas, imiquimod cream or destructive methods such as radiation, curettage, cryotherapy, laser ablation and photodynamic therapy, especially useful in nail bed involvement. Despite the early lesions, surgical excision is the preferred treatment option, regarding the potential malignant transformation risk.

    Objective: This study was designed to determine the frequency, pattern and management of surgical complications among patients with dengue fever. Design: Cross sectional study design was used. Settings: Hameed Latif Hospital, Lahore. Methods: From March - 2009 to December - 2011 total of 875 patients of dengue fever with positive anti-dengue immunoglobulin M (IgM) serology were included in this study. Complete blood count, liver function test, blood urea, serum creatinin, serum amylase were determined in all patients admitted with the diagnosis of dengue fever. All the patients were evaluated for the presence of surgical complications by physical examination and real time ultrasound abdomen. Patient had CT - abdomen and brain where it was required. Patients having surgical complications were managed in dengue ward and ICU with multidisciplinary approach. Data entry and analysis was done by using SPSS 16. Results: Among 875 patients with dengue fever, 491 (43.9%) patients were men and 384 (48.9%) were women with age range (18 - 70) years. Surgical complications were detected in 121 (13.8%) patients: acute cholecystitis in 46 (5.26%); acute pancreatitis in 19 (2.17%); injection abscess in 14 (1.6%); gastrointestinal bleed in 24 (2.74%); forearm compartment syndrome in 3 (0.34%); abdominal compartment syndrome in 2 (0.23%) and acute appendicitis, 4 (0.46%) patients. Cerebral bleed, retroperitoneal hematoma, abdominal wall hematoma and splenic rupture was seen among 3 (0.34%), 2 (0.23%), 3 (0.34%), and 1 (0.11%) patients, respectively. Out of 121 patients surgery was done in 20 (16.5%) patients while rest of 101 (83.5%) patients were managed conservatively. Two patients died. Conclusion: Surgical complications are common and should be suspected in every patient with dengue fever. Majority of surgical manifestations of dengue fever were managed conservatively however surgical intervention was done in certain cases with favorable outcome. (author)

    To prospectively evaluate the ability of radio frequency detection (RFD) system-embedded sponges to mitigate the incidence of retained surgical sponges (RSS) after emergency surgery. Emergency surgery patients are at high risk for retained foreign bodies. All emergent trauma and nontrauma cavitary operations over a 5-year period (January 2010-December 2014) were prospectively enrolled. For damage-control procedures, only the definitive closure was included. RFD sponges were used exclusively throughout the study period. Before closure, the sponge and instrument count was followed by RFD scanning and x-ray evaluation for retained sponges. RSS and near-misses averted using the RFD system were analyzed. In all, 2051 patients [median (range)], aged 41 (1-101) years, 72.2% male, 46.8% trauma patients, underwent 2148 operations (1824 laparotomy, 100 thoracotomy, 30 sternotomy, and 97 combined). RFD detected retained sponges in 11 (0.5%) patients (81.8%laparotomy, 18.2% sternotomy) before cavitary closure. All postclosure x-rays were negative. No retained sponges were missed by the RFD system. Body mass index was 29 (23-43), estimated blood loss 1.0 L (0-23), and operating room time 160 minutes (71-869). Procedures started after 18:00 to 06:00 hours in 45.5% of the patients. The sponge count was incorrect in 36.4%, not performed due to time constraints in 45.5%, and correct in 18.2%. The additional cost of using RFD-embedded disposables was $0.17 for a 4X18 laparotomy sponge and $0.46 for a 10 pack of 12ply, 4X8. Emergent surgical procedures are high-risk for retained sponges, even when sponge counts are performed and found to be correct. Implementation of a RFD system was effective in preventing this complication and should be considered for emergent operations in an effort to improve patient safety.

    Recent reports have suggested that caudal anesthesia may be associated with an increased risk of postoperative surgical complications. We examined our experience with caudal anesthesia in hypospadias repair to evaluate for increased risk of urethrocutaneous fistula or glanular dehiscence. All hypospadias repairs performed by a single surgeon in 2001-2014 were reviewed. Staged or revision surgeries were excluded. Patient age, weight, hypospadias severity, surgery duration, month and year of surgery, caudal anesthesia use, and postoperative complications were recorded. Bivariate and multivariate statistical analyses were performed. We identified 395 single-stage primary hypospadias repairs. Mean age was 15.6 months; 326 patients had distal (83%) and 69 had proximal (17%) hypospadias. Caudal anesthetics were used in 230 (58%) cases; 165 patients (42%) underwent local penile block at the discretion of the surgeon and/or anesthesiologist. Complications of urethrocutaneous fistula or glanular deshiscence occurred in 22 patients (5.6%) and were associated with caudal anesthetic use (OR 16.5, 95% CI 2.2-123.8, P = 0.007), proximal hypospadias (OR 8.2, 95% CI 3.3-20.0, P anesthesia was associated with an over 13-fold increase in the odds of developing postoperative surgical complications in boys undergoing hypospadias repair even after adjusting for urethral meatus location. Until further investigation occurs, clinicians should carefully consider the use of caudal anesthesia for children undergoing hypospadias repair. © 2017 John Wiley & Sons Ltd.

    We conducted a nationwide survey on perioperative management and antimicrobial prophylaxis of transvaginal mesh surgeries for pelvic organ prolapse in Japan to understand the practice and risk factors for surgical site infection (SSI). Health records of women undergoing tension-free vaginal mesh (TVM) surgeries from 2010 to 2012 were obtained from 135 medical centers belonging to the Japanese Society of Pelvic Organ Prolapse Surgery. The questionnaire addressed hospital volume, perioperative management, and SSI. Risk factors for SSI were investigated by comparing cases with and without SSI. The hospital volume among institutions varied from 0 to 248 per year (median 16.7). Preoperative hair removal, bowel preparation, and urine culture were routinely performed at 74 (55%), 66 (49%), and 24 (18%) hospitals, respectively. Prophylactic antimicrobials used were mostly first-generation (43%) or second-generation (42%) cephalosporin. SSI was reported in 86 of 9323 patients (0.92%). A multivariate analysis indicated lower hospital volume (odds ratio [OR], 0.995 [by 1-point increase]; P < 0.001), preoperative bowel preparation (OR, 2.08; P = 0.013), non-routine urine culture (OR, 3.00; P = 0.0006), and the use of antibiotics other than first-generation cephalosporin (OR, 5.29; P = 0.0011) as significant risk factors for SSI. In contrast, the cut-off points of hospital volume for preventing SSI was 116.7 cases (area under curve: 0.61). The prevalence of SSI in TVM surgeries was 0.92% in Japan. Lower hospital volume, bowel preparation, non-routine preoperative urine culture, and prophylactic antibiotics other than first-generation cephalosporin significantly elevated the incidence of SSI. © 2018 Wiley Periodicals, Inc.

    Left ventricular assist devices (LVADs) are increasingly used to treat patients with end-stage heart failure. These patients may develop acute noncardiac surgical problems around the time of LVAD implantation or, as survival continues to improve, chronic surgical problems as ambulatory patients remote from the LVAD implant. Previous reports of noncardiac surgical problems in LVAD patients included patients with older, first-generation devices and do not address newer, second-generation devices. We describe the frequency and management of noncardiac surgical problems encountered during LVAD support with these newer-generation devices to assist noncardiac surgeons involved in the care of patients with LVADs. We retrospectively reviewed the medical records of consecutive patients receiving LVADs at our institution. We collected data for any consultation by noncardiac surgeons within the scope of general surgery during LVAD support and subsequent treatment. Ninety-nine patients received implantable LVADs between 2003 and 2009 (first-generation, n = 19; second-generation, n = 80). Excluding intestinal hemorrhage, general surgical opinions were rendered for 34 patients with 49 problems, mostly in the acute recovery phase after LVAD implantation. Of those, 27 patients underwent 28 operations. Respiratory failure and intra-abdominal pathologies were the most common problems addressed, and LVAD rarely precluded operation. Patients with second-generation LVADs were more likely to survive hospitalization (P = .04) and develop chronic, rather than emergent, surgical problems. Patients with LVADs frequently require consultation from noncardiac surgeons within the scope of general surgeons and often require operation. Patients with second-generation LVADs are more likely to become outpatients and develop more elective surgical problems. Noncardiac surgeons will be increasingly involved in caring for patients with LVADs and should anticipate the problems unique to this patient

    Full Text Available Abstract Background Veno-arterial extracorporeal membrane oxygenation (ECMO is a common modality of circulatory assist device used in children. We assessed the outcome of children who had ECMO following repair of congenital cardiac defects (CCD and identified the risk factors associated with hospital mortality. Methods From April 1990 to December 2003, 53 patients required ECMO following surgical correction of CCD. Retrospectively collected data was analyzed with univariate and multivariate logistic regression analysis. Results Median age and weight of the patients were 150 days and 5.4 kgs respectively. The indications for ECMO were low cardiac output in 16, failure to wean cardiopulmonary bypass in 13, cardiac arrest in 10 and cardio-respiratory failure in 14 patients. The mean duration of ECMO was 143 hours. Weaning off from ECMO was successful in 66% and of these 83% were survival to hospital-discharge. 37.7% of patients were alive for the mean follow-up period of 75 months. On univariate analysis, arrhythmias, ECMO duration >168 hours, bleeding complications, renal replacement therapy on ECMO, arrhythmias and cardiac arrest after ECMO were associated with hospital mortality. On multivariate analysis, abnormal neurology, bleeding complications and arrhythmias after ECMO were associated with hospital mortality. Extra and intra-thoracic cannulations were used in 79% and 21% of patients respectively and extra-thoracic cannulation had significantly less bleeding complications (p = 0.031. Conclusion ECMO provides an effective circulatory support following surgical repair of CCD in children. Extra-thoracic cannulation is associated with less bleeding complications. Abnormal neurology, bleeding complications on ECMO and arrhythmias after ECMO are poor prognostic indicators for hospital survival.

    The aims of the current study were to determine whether pre-operative urinary tract infections in patients presenting acutely with neck of femur fractures resulted in a delay to surgery and whether such patients were at increased risk of developing post-operative surgical site infections. A retrospective review of all patients presenting with a neck of femur fracture, at a single centre over a one-year period. The hospital hip fracture database was used as the main source of data. UK University Teaching Hospital. All patients ( n  = 460) presenting across a single year study period with a confirmed hip fracture. The presence of pre-operative urinary tract infection, the timing of surgical intervention, the occurrence of post-operative surgical site infection and the pathogens identified. A total of 367 patients were operated upon within 24 hours of admission. Urinary infections were the least common cause of delay. A total of 99 patients (21.5%) had pre-operative urinary tract infection. Post-operatively, a total of 57 (12.4%) patients developed a surgical site infection. Among the latter, 31 (54.4%) did not have a pre-operative urinary infection, 23 (40.4%) patients had a pre-operative urinary tract infection, 2 had chronic leg ulcers and one patient had a pre-operative chest infection. Statistically, there was a strong relationship between pre-operative urinary tract infection and the development of post-operative surgical site infection ( p -value: 0.0005). The results of our study indicate that pre-operative urinary tract infection has a high prevalence amongst those presenting with neck of femur fractures, and this is a risk factor for the later development of post-operative surgical site infection.

    Results of a radioisotope method of the gastro-esophageal reflux are presented in patients with achalasia cardiae after different types of surgical treatment. Both Belsey-Mark and modified Nissen techniques are effective in preventing spontaneous gastroesophageal reflux, however 2 patients after Nissen fundoplication demonstrated gastro-esophageal reflux provoked by abdominal compression. This simple, noninvasive and physiologic method is an appropriate diagnostic tool for evaluating the efficiency of different anti reflux surgical techniques and is recommended for follow-up studies of patients after gastro-esophageal surgical intervention.

    Most patient education involves passive learning. To improve patient education regarding surgery, an active learning workshop-based teaching method is proposed. The objective of this study was to assess level of patient surgical knowledge, achievement of workshop learning objectives, patient apprehension about future surgery, and participant workshop satisfaction after completing a surgical training workshop. A four-station workshop (surgical scrub, surgical suture, laparoscopic surgery, and robotic surgery) was developed to teach four important components of the surgical process. Healthy, surgery-naive adolescents were enrolled to attend this 1-h workshop-based training program. Training received by participants was technically and procedurally identical to training received by actual surgeons. Pre- and post-workshop questionnaires were used to assess learning outcomes. There were 1312 participants, with a mean age 15.9 ± 1.1 years and a gender breakdown of 303 males and 1009 females. For surgical knowledge, mean pre-workshop and post-workshop scores were 6.1 ± 1.5 and 7.5 ± 1.5 (out of 10 points), respectively (p education is an effective way to improve understanding of surgery-related processes. This teaching method may also decrease apprehension that patients or potential patients harbor regarding a future surgical procedure.

    Surgical myotomy of the lower esophageal sphincter has a 5-year success rate of approximately 91 %. Peroral endoscopic myotomy can provide similar results for controlling dysphagia. Some patients experience either persistent or recurrent dysphagia after myotomy. We present here a retrospective analysis of our experience with redo myotomy for recurrent dysphagia in patients with achalasia. From March 1996 to February 2015, 234 myotomies for primary or recurrent achalasia were performed in our center. Fifteen patients (6.4 %) had had a previous myotomy and were undergoing surgical redo myotomy (n = 9) or endoscopic redo myotomy (n = 6) for recurrent symptoms. Patients presented at a median of 10.4 months after previous myotomy. Median preoperative Eckardt score was 6. Among the nine patients undergoing surgical myotomy, three esophageal perforations occurred intraoperatively (all repaired immediately). Surgery lasted 111 and 62 min on average (median) in the surgical and peroral endoscopic myotomy (POEM) groups, respectively. No postoperative complications occurred in either group. Median postoperative stay was 3 and 2.5 days in the surgical and POEM groups, respectively. In the surgical group, Eckardt score was dysphagia. Preliminary results using POEM indicate that the technique can be safely used in patients who have undergone previous surgical myotomy.

    To report a study of patients' views of patient-centred care. The study aimed to explore patients' understanding and conceptualization of patient-centred care and link it to existing literature on the topic. Patient-centred care currently lacks a widely accepted definition, with much of the literature based on definitions formulated by health professionals and researchers. Qualitative research study grounded in phenomenology. Interpersonal interviews were conducted with ten participants who were patients in a surgical ward in a large metropolitan hospital in South Australia in 2010. Participants were unfamiliar with the concept of patient-centred care, but despite this, were able to describe what the term meant to them and what they wanted from their care. Patients equated the type and quality of care they received with the staff that provided it and themes of connectedness, involvement and attentiveness were prevalent in their descriptions of what they wanted from their care. Ensuring that patients have a voice in the definition and conceptualization of patient-centred care is essential and further and regular consultation with patients about their needs and priorities will ensure an integrated approach to patient-centred care. © 2012 Blackwell Publishing Ltd.

    OBJECT Case selection for the surgical treatment of arteriovenous malformations (AVMs) of the eloquent motor area remains challenging. The aim of this study was to determine the risk factors for worsened muscle strength after surgery in patients with this disorder. METHODS At their hospital the authors retrospectively studied 48 consecutive patients with AVMs involving motor cortex and/or the descending pathway. All patients had undergone preoperative functional MRI (fMRI) and diffusion tensor imaging (DTI), followed by resection. Both functional and angioarchitectural factors were analyzed with respect to the change in muscle strength. Functional factors included lesion-to-corticospinal tract distance (LCD) on DTI and lesion-to-activation area distance (LAD) and cortical reorganization on fMRI. Based on preoperative muscle strength, the changes in muscle strength at 1 week and 6 months after surgery were defined as short-term and long-term surgical outcomes, respectively. Statistical analysis was performed using the statistical package SPSS (version 20.0.0, IBM Corp.). RESULTS Twenty-one patients (43.8%) had worsened muscle strength 1 week after surgery. However, only 10 patients (20.8%) suffered from muscle strength worsening 6 months after surgery. The LCD was significantly correlated with short-term (p 0 mm (p = 0.009) and LCD > 5 mm (p 0 mm group and LCD > 5 mm group (p = 0.116). Nidus size was the other significant predictor of short-term (p = 0.021) and long-term (p = 0.016) outcomes. For long-term outcomes, the area under the ROC curve (AUC) was 0.728, and the cutoff point was 3.6 cm. Spetzler-Martin grade was not associated with short-term surgical outcomes (0.143), although it was correlated with long-term outcomes (0.038). CONCLUSIONS An AVM with a nidus in contact with tracked eloquent fibers (LCD = 0) and having a large size is more likely to be associated with worsened muscle strength after surgery in patients with eloquent motor area AVMs. Surgical

    To assess whether different diagnostic and prognostic cutoff values of procalcitonin should be considered in surgical and in medical patients with septic shock. Prospective observational study. Intensive care unit of the Avicenne teaching hospital, France. All patients with septic shock or noninfectious systemic inflammatory response syndrome within 48 hrs after admission. None. Patients were allocated to one of the following groups: group 1 (surgical patients with septic shock), group 2 (surgical patients with noninfectious systemic inflammatory response syndrome), group 3 (medical patients with septic shock), and group 4 (medical patients with noninfectious systemic inflammatory response syndrome). Procalcitonin at study entry was compared between group 1 and group 2 and between group 3 and group 4 to determine the diagnostic cutoff value in surgical and in medical patients, respectively. Procalcitonin was compared between survivors and nonsurvivors from group 1 and group 3 to determine its prognostic cutoff value. One hundred forty-three patients were included: 31 in group 1, 36 in group 2, 36 in group 3, and 40 in group 4. Median procalcitonin levels (ng/mL [interquartile range]) were higher in group 1 than in group 3 (34.00 [7.10-76.00] vs. 8.40 [3.63-24.70], p = .01). In surgical patients, the best diagnostic cutoff value was 9.70 ng/mL, with 91.7% sensitivity and 74.2% specificity. In medical patients, the best diagnostic cutoff value was 1.00 ng/mL, with 80% sensitivity and 94% specificity. Procalcitonin was a reliable early prognostic marker in medical but not in surgical patients with septic shock. A cutoff value of 6.00 ng/mL had 76% sensitivity and 72.7% specificity for separating survivors from nonsurvivors. The diagnostic cutoff value of procalcitonin was higher in surgical than in medical patients. Early procalcitonin was of prognostic interest in medical patients.

    Emergency abdominal surgery is associated with high morbidity and mortality rates, especially in the elderly patients, but prompt diagnoses and treatment should not be delayed. We conducted a retrospective review (1) to identify risk factors for morbidity and mortality among elderly patients admitted for emergent surgery of perforated peptic ulcers; and (2) to determine whether there were any differences between those who are 70-79 years old and those 80 years old and older. 94 patients who were older than 70 years old and underwent emergency surgery for perforated peptic ulcer between 2000 and 2004 in our institution were reviewed retrospectively. The following variables were followed: age, sex, comorbidity, previous medications, time from onset of symptoms/signs to surgery, time from arrival in emergent room to surgery, perioperative risks, operative findings, type of operation, morbidity, mortality and length of hospital stay. The age, morbidity, mortality and the length of intensive care unit stay were increased in Group 2 (>80 yrs) than Group 1 (70 to 79 yrs), but they did not achieve significant differences statistically. Time from symptoms/signs to emergency room over 24 hours, American Society of Anesthesiologist grade over IV and limited procedure showed significant contributions to postoperative morbidity on univariate analysis. Comorbidity, time from emergency room to operation room over 12 hours, American Society of Anesthesiologists grade over IV, peri-operative blood transfusion, postoperative morbidity and duration of ICU stays over 5 days were significant factors contributed to mortality on univariate analysis. Further analysis showed comorbidity, peri-operative blood transfusion, and postoperative morbidity were independent and predictive factors of mortality on multivariate model. Although perforated peptic ulcer in the elderly patients is associated with high morbidity and mortality, we should not delay the surgical intervention for patients with

    Objective: To compare the frequency of surgical site infections in patients with type II diabetes undergoing laparoscopic cholecystectomy as compared with non-diabetic patients. Study Design: Cohort study. Place and Duration of Study: Surgical Unit 2, Services Hospital, Lahore, from May to October 2012. Methodology: Patients were divided into two groups of 60 each, undergoing laparoscopic cholecystectomy. Group A comprised non-diabetic patients and group B comprised type II diabetic patients. Patients were followed postoperatively upto one month for the development of SSIs. Proportion of patients with surgical site infections or otherwise was compared between the groups using chi-square test with significance of p < 0.05. Results: In group A, 35 patients were above the age of 40 years. In group B, 38 patients were above the age of 40 years. Four patients in group A developed a surgical site infection. Seven patients in group B developed SSIs (p = 0.07). Conclusion: Presence of diabetes mellitus did not significantly affect the onset of surgical site infection in patients undergoing laparoscopic cholecystectomy. (author)

    Purpose To develop a machine learning model that allows high-risk breast lesions (HRLs) diagnosed with image-guided needle biopsy that require surgical excision to be distinguished from HRLs that are at low risk for upgrade to cancer at surgery and thus could be surveilled. Materials and Methods Consecutive patients with biopsy-proven HRLs who underwent surgery or at least 2 years of imaging follow-up from June 2006 to April 2015 were identified. A random forest machine learning model was developed to identify HRLs at low risk for upgrade to cancer. Traditional features such as age and HRL histologic results were used in the model, as were text features from the biopsy pathologic report. Results One thousand six HRLs were identified, with a cancer upgrade rate of 11.4% (115 of 1006). A machine learning random forest model was developed with 671 HRLs and tested with an independent set of 335 HRLs. Among the most important traditional features were age and HRL histologic results (eg, atypical ductal hyperplasia). An important text feature from the pathologic reports was "severely atypical." Instead of surgical excision of all HRLs, if those categorized with the model to be at low risk for upgrade were surveilled and the remainder were excised, then 97.4% (37 of 38) of malignancies would have been diagnosed at surgery, and 30.6% (91 of 297) of surgeries of benign lesions could have been avoided. Conclusion This study provides proof of concept that a machine learning model can be applied to predict the risk of upgrade of HRLs to cancer. Use of this model could decrease unnecessary surgery by nearly one-third and could help guide clinical decision making with regard to surveillance versus surgical excision of HRLs. © RSNA, 2017.

    Surgery is the cornerstone for clinical management of patients with borderline ovarian tumors (BOT). As these patients have an excellent overall prognosis, perioperative morbidity is the critical point for decision making when the treatment strategy is developed and the primary surgical approach is defined. Clinical and surgical parameters of patients undergoing surgery for primary BOT at our institutions between 1993 and 2008 were analyzed with regard to perioperative morbidity depending on the surgical approach (laparotomy vs. laparoscopy). A total of 105 patients were analyzed (44 with primary laparoscopy [42%], 61 with primary laparotomy [58%]). Complete surgical staging was achieved in 33 patients at primary surgical approach (31.4%) frequently leading to formal indication of re-staging procedures. Tumor rupture was significantly more frequent during laparoscopy compared to laparotomy (29.5% vs. 13.1%, p = 0.038) but no other intraoperative complications were seen in laparoscopic surgery in contrast to 7 of 61 laparotomies (0% vs. 11.5%, p = 0.020). Postoperative complication rates were similar in both groups (19.7% vs. 18.2%, p = 0.848). Irrespective of the surgical approach, surgical management of BOT has acceptable rates of perioperative complications and morbidity. Choice of initial surgical approach can therefore be made independent of complication-concerns. As the recently published large retrospective AGO ROBOT study observed similar oncologic outcome for both approaches, laparoscopy can be considered for staging of patients with BOT if this appears feasible. An algorithm for the surgical management of BOT patients has been developed.

    The diagnosis and surgical treatment of patients with Marfan syndrome remain controversial. It is of utmost importance to identify patients at risk for acute aortic events to establish the correct surgical timing and the appropriate surgical treatment. From May 2008 to December 2012, 500 patients were screened at the Marfan Presidium of the Tor Vergata University Hospital of Rome (Italy). Patients were evaluated by a cardiac surgeon, including echocardiographic, orthopedic, ophthalmologic and dental examinations. All patients received genetic counseling, and genetic sampling was performed if appropriate. The diagnosis of Marfan syndrome was confirmed in 146 patients (29.2%). Fifty-four patients (37%) underwent cardiac surgery on the aortic root, 4 patients had surgery on the mitral valve, 13 patients had combined surgery; 11 cases were emergent surgery for acute aortic dissection. Twenty-eight patients (52%) were operated on at our Division: 13 underwent valve-sparing aortic root replacement (David procedure), 1 underwent Yacoub remodeling procedure and 14 underwent Bentall procedure. Following the establishment of the Marfan Center, the David aortic valve-sparing operation was the most frequently performed procedure compared to the previous period of surgical activity (63 vs 22%, psyndromes. Early surgical treatment is recommended in these patients to achieve optimal results of valve-sparing procedures and life-saving management, especially for patients who live far away from a cardiac surgery center.

  12. Anesthesia and perioperative management of colorectal surgical patients - A clinical review (Part 1

    2012-01-01

    Full Text Available Colorectal surgery is commonly performed for colorectal cancer and other pathology such as diverticular and inflammatory bowel disease. Despite significant advances, such as laparoscopic techniques and multidisciplinary recovery programs, morbidity and mortality remain high and vary among surgical centers. The use of scoring systems and assessment of functional capacity may help in identifying high-risk patients and predicting complications. An understanding of perioperative factors affecting colon blood flow and oxygenation, suppression of stress response, optimal fluid therapy, and multimodal pain management are essential. These fundamental principles are more important than any specific choice of anesthetic agents. Anesthesiologists can significantly contribute to enhance recovery and improve the quality of perioperative care.

    Adults and children are required to fast before anaesthesia to reduce the risk of regurgitation and aspiration of gastric contents. However, prolonged periods of fasting are unnecessary and may cause complications. This study was conducted to evaluate preoperative fasting period in our centre and compare it with the ASA recommendations and factors that influence fasting periods. This is a cross-sectional study of preoperative fasting times among elective surgical patients. A total numbers of 260 patients were interviewed as they arrived at the reception area of operating theatre using questionnaire. Majority of patients (98.1%) were instructed to fast from midnight. Fifteen patients (5.8%) reported that they were told the importance of preoperative fasting. The mean fasting period were 15.9±2.5 h (range 12.0-25.3 h) for solids and 15.3±2.3 h (range 12.0-22.0 h) for liquids. The mean duration of fasting was significantly longer for patients operated after midday compared to those operated before midday, pfasting periods were 7.65 times longer for clear liquid and 2.5 times for solids than the ASA guidelines. It is imperative that the Hospital should establish Preoperative fasting policies and teach the staff who should ensure compliance with guidelines.

    The study was aimed at determining the dynamics of the emotional state and factors influencing thereupon in patients presenting with atherosclerosis of lower limb arteries and undergoing surgical treatment. The study included a total of sixty-five 36-to-90-year-old patients (53 men and 12 women) subjected to examination twice - prior to surgery and before discharge by means of semi-structured interview, self-assessment scale of feeling and mood, methods "Integrative test of anxiety" and "Type of attitude towards the disease" (TOBOL), questionnaire for assessing health-related quality of life SF-36 and Krantz questionnaire in order to determine the position in the therapeutic process. After surgery (on postoperative day 7-10 of hospital stay) the patients demonstrated a decrease in the degree of anxiety and somatic complaints. Women (p=0.037), patients with the duration of the disease from 1 to 8 years (p=0.033), with signs of personality anxiety (p≤0.045), disadaptive variants of attitude to disease and treatment (p≤0.05), as well as clearly manifesting mistrust for medical recommendations (p=0.014) belong to a group of risk of emotional stress at the postoperative stage. Clinical and socio-demographic determinants are comparatively less important in formation of pronounced anxiety of postoperative period than the patient's personality.

    Background: The aim of this study was to conduct external validation of risk prediction scores for invasive candidiasis. Methods: We conducted a prospective observational study in a 12-bedded adult medical/surgical Intensive Care Unit (ICU) to evaluate Candida score >3, colonization index (CI) >0.5, corrected CI >0.4 (CCI), and Ostrosky's clinical prediction rule (CPR). Patients' characteristics and risk factors for invasive candidiasis were noted. Patients were divided into two groups; invasive candidiasis and no-invasive candidiasis. Results: Of 198 patients, 17 developed invasive candidiasis. Discriminatory power (area under receiver operator curve [AUROC]) for Candida score, CI, CCI, and CPR were 0.66, 0.67, 0.63, and 0.62, respectively. A large number of patients in the no-invasive candidiasis group (114 out of 181) were exposed to antifungal agents during their stay in ICU. Subgroup analysis was carried out after excluding such patients from no-invasive candidiasis group. AUROC of Candida score, CI, CCI, and CPR were 0.7, 0.7, 0.65, and 0.72, respectively, and positive predictive values (PPVs) were in the range of 25%–47%, along with negative predictive values (NPVs) in the range of 84%–96% in the subgroup analysis. Conclusion: Currently available risk prediction scores have good NPV but poor PPV. They are useful for selecting patients who are not likely to benefit from antifungal therapy. PMID:28904481

    OBJECTIVE It is becoming increasingly necessary for surgeons to provide evidence supporting cost-effectiveness of surgical treatment for cervical spine pathology. Anticipating surgical risk is critical in accurately evaluating the risk/benefit balance of such treatment. Determining the risk and cost-effectiveness of surgery, complications, revision procedures, and mortality rates are the most significant limitations. The purpose of this study was to determine independent risk factors for medical complications (MCs), surgical complications (SCs), revisions, and mortality rates following surgery for patients with cervical spine pathology. The most relevant risk factors were used to structure an index that will help quantify risk and anticipate failure for such procedures. METHODS The authors of this study performed a retrospective review of the National Inpatient Sample (NIS) database for patients treated surgically for cervical spine pathology between 2001 and 2010. Multivariate models were performed to calculate the odds ratio (OR) of the independent risk factors that led to MCs and repeated for SCs, revisions, and mortality. The models controlled for age ( 65 years old), sex, race, revision status (except for revision analysis), surgical approach, number of levels fused/re-fused (2-3, 4-8, ≥ 9), and osteotomy utilization. ORs were weighted based on their predictive category: 2 times for revision surgery predictors and 4 times for mortality predictors. Fifty points were distributed among the predictors based on their cumulative OR to establish a risk index. RESULTS Discharges for 362,989 patients with cervical spine pathology were identified. The mean age was 52.65 years, and 49.47% of patients were women. Independent risk factors included medical comorbidities, surgical parameters, and demographic factors. Medical comorbidities included the following: pulmonary circulation disorder, coagulopathy, metastatic cancer, renal failure, congestive heart failure

    Most surgical wounds heal by primary intention, that is to say, the edges of the wound are brought together with sutures, staples, adhesive glue or clips. However, some wounds may be left open to heal (if there is a risk of infection, or if there has been significant tissue loss), and are known as 'surgical wounds healing by secondary intention'. They are estimated to comprise approximately 28% of all surgical wounds and are frequently complex to manage. However, they are under researched and little is known of their impact on patients' lives. To explore patients' views and experiences of living with a surgical wound healing by secondary intention. A qualitative, descriptive approach. Participants were recruited from acute and community nursing services in two locations in the North of England characterised by high levels of deprivation and diverse populations. Participants were aged 18 years or older and had at least one surgical wound healing by secondary intention, which was slow to heal. Purposeful sampling was used to include patients of different gender, age, wound duration and type of surgery (general, vascular and orthopaedic). Twenty people were interviewed between January and July 2012. Semi-structured interviews were conducted, guided by use of a topic guide developed with input from patient advisors. Data were thematically analysed using steps integral to the 'Framework' approach to analysis, including familiarisation with data; development of a coding scheme; coding, charting and cross comparison of data; interpretation of identified themes. Alarm, shock and disbelief were frequently expressed initial reactions, particularly to "unexpected" surgical wounds healing by secondary intention. Wound associated factors almost universally had a profound negative impact on daily life, physical and psychosocial functioning, and wellbeing. Feelings of frustration, powerlessness and guilt were common and debilitating. Patients' hopes for healing were often

  2. Recent developments in pharmacologic prophylaxis of atrial fibrillation in patients undergoing surgical revascularization.

    Atrial fibrillation is a frequent complication after CABG. It occurs in 20-50% of patients, most often between the 2nd and 3rd postoperative day. About 40 % of patients experience more than 1 episode. Postoperative AF (POAF) is associated with an increase in adverse events and hospital stay and, therefore, costs of care. The incidence of POAF is not influenced by the technique of CABG with or without cardiopulmonary by-pass Neurohormonal activation, electrolyte imbalance, fluid overload, surgical practices and finally an exaggerated inflammatory response has been proposed to be etiological factor. Advanced age, history of AF or heart failure, COPD, postoperative withdrawal of beta-blockers are independent risk factors of postoperative AF. Conversely, postoperative administration of beta-blockers, ACE inhibitors, potassium supplementation and NSAID were associated with a reduced risk of POAF. Pharmacological strategies for prevention of POAF may be divided in two main groups : the first one encompasses the use of antiarrhythmic drugs (amiodarone, metoprolol, sotalol) before and /or after surgery and has been extensively investigated in the last two decades. Recently an Italian study has shown that PUFA administration during hospitalization in patients undergoing CABG significantly decreased the incidence of POAF and was associated with a shorter hospital stay. Since an exaggerated inflammatory reaction may play a significant role in POAF, treatments directed to antagonize inflammation are presently under investigation. Despite different action mechanisms both hydrocortisone and statins have been shown to decrease post-operative AF risk. These two prophylactic regimens are not mutually exclusive and some data suggest that their association may be useful to further decrease the risk of POAF.

  3. Surgical strategies in patients with gallbladder cancer: nihilism to optimism.

    Gallbladder cancer is an aggressive disease with dismal results of surgical treatment and a poor prognosis. However, over the last few decades selected groups have reported improved results with aggressive surgery for gallbladder cancer. Review of recent world literature was done to provide an update on the current concepts of surgical treatment of this disease. Long-term survival is possible in early stage gallbladder carcinoma. Tis and T1a gallbladder carcinoma can be treated with simple cholecystectomy only. However, in T1b and beyond cancers, aggressive surgery (extended cholecystectomy) is important in improving the long-term prognosis. Laparoscopic cholecystectomy should not be performed where there is a high index of suspicion of malignancy due to the frequent association with factors (such as gallbladder perforation and bile spill) which may lead to implantation of cancer cells and dissemination. Surgical resection for advanced carcinoma gallbladder is recommended only if a potentially curative R0 resection is possible. Aggressive surgery with vascular and multivisceral resection has been shown to be feasible albeit with an increase in mortality and morbidity. However, the true benefit of these radical resections is yet to be realized, as the actual number of long-term survivors of advanced gallbladder carcinoma is few. Surgery for gallbladder carcinoma, like other malignancies, has the potential to be curative only in local or regional disease. Pattern of loco-regional spread of disease dictates the surgical procedure. Radical surgery improves survival in early gallbladder carcinoma. The long-term benefit of aggressive surgery for advanced disease is unclear and may be offset by the high mortality and morbidity. Copyright 2006 Wiley-Liss, Inc.

    After major operations, hypoxaemia is common in the late postoperative period in the surgical ward. Recent studies of humans after major operations showed that such hypoxaemia may be related to the development of myocardial ischaemia and cardiac arrhythmias, even in patients with no preoperative...... signs or symptoms of coronary artery disease. Experimental studies have shown an adverse effect of tissue hypoxia on wound healing and on resistance to bacterial wound infections. Finally, mental confusion and surgical delirium may be related to inadequate arterial oxygenation during the late...

  5. Setting the Threshold for Surgical Prevention in Women at Increased Risk of Ovarian Cancer.

    2018-01-01

    The number of ovarian cancer cases is predicted to rise by 14% in Europe and 55% worldwide over the next 2 decades. The current absence of a screening program, rising drug/treatment costs, and only marginal improvements in survival seen over the past 30 years suggest the need for maximizing primary surgical prevention to reduce the burden of ovarian cancer. Primary surgical prevention through risk-reducing salpingo-oophorectomy (RRSO) is well established as the most effective method for preventing ovarian cancer. In the UK, it has traditionally been offered to high-risk women (>10% lifetime risk of ovarian cancer) who have completed their family. The cost-effectiveness of RRSO in BRCA1/BRCA2 carriers older than 35 years is well established. Recently, RRSO has been shown to be cost-effective in postmenopausal women at lifetime ovarian cancer risks of 5% or greater and in premenopausal women at lifetime risks greater than 4%. The acceptability, uptake, and satisfaction with RRSO at these intermediate-risk levels remain to be established. Prospective outcome data on risk-reducing salpingectomy and delayed-oophorectomy for preventing ovarian cancer is lacking, and hence, this is best offered for primary prevention within the context and safe environment of a clinical trial. An estimated 63% of ovarian cancers occur in women with greater than 4% lifetime risk and 53% in those with 5% or greater lifetime-risk. Risk-reducing salpingo-oophorectomy can be offered for primary surgical prevention to women at intermediate risk levels (4%-5% to 10%). This includes unaffected women who have completed their family and have RAD51C, RAD51D, or BRIP1 gene mutations; first-degree relatives of women with invasive epithelial ovarian cancer; BRCA mutation-negative women from high-risk breast-and-ovarian cancer or ovarian-cancer-only families.

    Full Text Available Objectives: During laparoscopic cholecystectomy, the removal of the gall bladder, pyrolysis occurs in the peritoneal cavity. Chemical substances which are formed during this process escape into the operating room through trocars in the form of surgical smoke. The aim of this study was to identify and quantitatively measure a number of selected chemical substances found in surgical smoke and to assess the risk they carry to medical personnel. Material and Methods: The study was performed at the Maria Skłodowska-Curie Memorial Provincial Specialist Hospital in Zgierz between 2011 and 2013. Air samples were collected in the operating room during laparoscopic cholecystectomy. Results: A complete qualitative and quantitative analysis of the air samples showed a number of chemical substances present, such as aldehydes, benzene, toluene, ethylbenzene, xylene, ozone, dioxins and others. Conclusions: The concentrations of these substances were much lower than the hygienic standards allowed by the European Union Maximum Acceptable Concentration (MAC. The calculated risk of developing cancer as a result of exposure to surgical smoke during laparoscopic cholecystectomy is negligible. Yet it should be kept in mind that repeated exposure to a cocktail of these substances increases the possibility of developing adverse effects. Many of these compounds are toxic, and may possibly be carcinogenic, mutagenic or genotoxic. Therefore, it is necessary to remove surgical smoke from the operating room in order to protect medical personnel.

    Esophageal achalasia is a relatively rare disease that occurs usually in middle-aged patients. The laparoscopic Heller-Dor (LHD) procedure is the gold-standard surgical treatment for esophageal achalasia. There are many studies on the pathology and surgical outcome of esophageal achalasia from various perspectives, but there are no studies on gender differences in both the pathology and surgical outcome. This study aimed to evaluate gender differences in the surgical outcome with the LHD procedure and in the pathology of esophageal achalasia patients. The study included 474 LHD-treated patients who were postoperatively followed up for 6 months or more. The patients were divided into 2 groups by gender, to compare the preoperative pathology, surgical outcome, symptom scores before and after LHD, symptom score improvement frequency, and patient satisfaction with the surgery. The study population consisted of 248 male and 226 female, having a mean age of 45.1 years. There were no gender differences in the preoperative pathology, but a significantly lower BMI (p achalasia were characterized by low BMI, less esophageal dilation, and increased frequency and severity of chest pain. LHD improved the chest pain in the female patients, whereas the surgical outcome and satisfaction with the surgery were excellent regardless of gender.

    Full Text Available Background: Obstructive sleep apnea (OSA is often not diagnosed in patients presenting for surgical procedures thereby increasing the incidence of adverse perioperative course. Early diagnosis of this disease is important in modifying anesthetic management as well as utilizing specific means which may decrease the complications and improve the patient outcome. Methods: Patients greater than eighteen years of age, ASA I-III scheduled for elective surgical procedures under anesthesia were randomly selected. Their demographic data, diagnosis and nature of surgery were noted in a semi-structured performa. They were then screened for the presence of OSA with the help of a STOP BANG questionnaire. Results : This study included two hundred four patients randomly selected. Slight female predominance was seen in this sample (55.4%. Mean age of the subjects was 42.7 years (SD=15.08. 24.5% subjects were at high risk for OSA (STOP-BANG>3 with a male predominance (72% versus 37% in low risk group; X 2 =18.62; P<0.001. High risk OSA subjects had higher prevalence of cardiovascular risk factors (57% vs. 11.7% in low risk group; X 2 =33.35; P<0.001. Similarly, this group had a higher prevalence of asthma and chronic obstructive pulmonary disease (COPD (14% versus 3.8% in low risk group; X 2 =6.54; P=0.03. Prevalence of diabetes mellitus (22% and hypothyroidism (6% was also higher in this group (5.2% and 1.9% in low risk group respectively; X 2 =15.42; P<0.001. Conclusion : High degree of suspicion and knowledge of association of OSA and medical diseases may help in detection of such cases and decrease the rate of perioperative complications thus improving patients safety.

    Retained surgical instruments (RSI) are one of the most serious preventable complications in operating room settings, potentially leading to profound adverse effects for patients, as well as costly legal and financial consequences for hospitals. Safety measures to eliminate RSIs have been widely adopted in the United States and abroad, but despite widespread efforts, medical errors with RSI have not been eliminated. Through a systematic review of recent studies, we aimed to identify the impact of radio frequency identification (RFID) technology on reducing RSI errors and improving patient safety. A literature search on the effects of RFID technology on RSI error reduction was conducted in PubMed and CINAHL (2000-2016). Relevant articles were selected and reviewed by 4 researchers. After the literature search, 385 articles were identified and the full texts of the 88 articles were assessed for eligibility. Of these, 5 articles were included to evaluate the benefits and drawbacks of using RFID for preventing RSI-related errors. The use of RFID resulted in rapid detection of RSI through body tissue with high accuracy rates, reducing risk of counting errors and improving workflow. Based on the existing literature, RFID technology seems to have the potential to substantially improve patient safety by reducing RSI errors, although the body of evidence is currently limited. Better designed research studies are needed to get a clear understanding of this domain and to find new opportunities to use this technology and improve patient safety.

    Objective: To observe the prevalence of recognised and unrecognised depression among in-patients. Methods: The cross-sectional study was conducted from June 2012 to May 2013 at a tertiary care hospital in Karachi, and comprised patients admitted in the Medicine and Surgical departments at the time. Patients with known history of depression or on anti-depressants or on anti-psychotics, or with suicidal attempt were excluded. The prevalence of unrecognised depression was then perceived using Patient Health Qurstionnaire-9. Statistical analysis was performed using SPSS 20. Results: Of the 1180 patients, 432(36.6 percent) either had history of depression or on were on anti-depressants. The study sample, as such, comprised 748(65 percent), and of them 399(53 percent) were from the Medicine and 349(47 percent) patients were from Surgery department. Prevalence of recognised depression was 36.6 percent; 48 percent in Medical and 14 percent in Surgical patients. Unrecognised depression was 51.2 percent; 45.3 percent in Medical and 53.6 in Surgical patients. Overall prevalence was 87.9 percent; 93.4 percent in Medical and 53 percent in Surgical patients. Gender was not found to be significantly associated with depression in Medical (p= 0.367) and Surgical (p=0.606) patients. No depression was found in 48(12 percent) Medical patients and 131(37.5 percent) Surgical patients. Conclusion: More than one-third of in-patients had co-morbid depression diagnoses, mostly unrecognised by their clinicians. (author)

    Laparoscopic appendectomy (LA) is increasingly being performed in the United States, despite controversy about differences in infectious complication rates compared with open appendectomy (OA). Subpopulations exist in which infectious complication rates, both surgical site and organ space, differ with respect to LA compared with OA. All appendectomies in the National Surgical Quality Improvement Program database were analyzed with respect to surgical site infection (SSI) and organ space infection (OSI). Multivariate logistic regression analysis identified independent predictors of SSI or OSI. Probabilities of SSI or OSI were determined for subpopulations to identify when LA was superior to OA. From 2005 to 2009, there were 61,830 appendectomies performed (77.5% LA), of which 9,998 (16.2%) were complicated (58.7% LA). The risk of SSI was considerably lower for LA in both noncomplicated and complicated appendicitis. Across all ages, body mass index, renal function, and WBCs, LA was associated with a lower probability of SSI. The risk of OSI was considerably greater for LA in both noncomplicated and complicated appendicitis. In complicated appendicitis, OA was associated with a lower probability of OSI in patients with WBC >12 cells × 10(3)/μL. In noncomplicated appendicitis, OA was associated with a lower probability of OSI in patients with a body mass index OSI, however, SSI is consistently lower in LA patients.

    To review and summarize the surgical techniques and their outcomes for the treatment of lumbar spondylolysis in young patients by direct surgical repair. Both home and abroad literature on the surgical techniques and their outcomes respectively for the treatment of lumbar spondylolysis in young patients by direct surgical repair was reviewed extensively and summarized. Direct surgical repair of lumbar spondylolysis can offer a simple reduction and fixation for the injured vertebra, which is also in accord with normal anatomy and physiology. In this way, normal anatomy of vertebra can be sustained. As reported surgical techniques of direct repair, such as single lag screw, hook screw, cerclage wire, pedicle screw cable, pedicle screw rod, and pedicle screw hook system, they all can provide acceptable results for lumbar spondylolysis in young patients. Furthermore, to comply strictly with the inclusion criteria of surgical management and select the appropriate internal fixation can also contribute to a good effectiveness. Within the various methods of internal fixation, pedicle screw hook system has been widely recognized. Pedicle screw hook system fixation is simple and safe clinically. With the gradual improvement of this method and the development of minimally invasive technologies, it will have broad application prospects.

    Full Text Available In incidental aneurysms, endovascular treatment can lead to post-procedural headaches. We studied the difference of surgical clipping vs. endovascular coiling in concern to post-procedural headaches in patients with ruptured aneurysms. Sixtyseven patients with aneurysmal subarachnoidal haemorrhage were treated in our department from September 1st 2015 - September 1st 2016. 43 Patients were included in the study and the rest was excluded because of late recovery or highgrade subarachnoid bleedings. Twenty-two were surgical treated and twenty-one were interventionally treated. We compared the post-procedural headaches at the time points of 24 h, 21 days, and 3 months after treatment using the visual analog scale (VAS for pain. After surgical clipping the headache score decreased for 8.8 points in the VAS, whereas the endovascular treated population showed a decrease of headaches of 3.3 points. This difference was highly statistical significant and remained significant even after 3 weeks where the pain score for the surgically treated patients was 0.68 and for the endovascular treated 1.8. After 3 months the pain was less than 1 for both groups with surgically treated patients scoring 0.1 and endovascular treated patients 0.9 (not significant. Clipping is relieving the headaches of patients with aneurysm rupture faster and more effective than endovascular coiling. This effect stays significant for at least 3 weeks and plays a crucial role in stress relieve during the acute and subacute ICU care of such patients.

    To examine how surgeons use the "fix-it" model to communicate with patients before high-risk operations. The "fix-it" model characterizes disease as an isolated abnormality that can be restored to normal form and function through medical intervention. This mental model is familiar to patients and physicians, but it is ineffective for chronic conditions and treatments that cannot achieve normalcy. Overuse may lead to permissive decision making favoring intervention. Efforts to improve surgical decision making will need to consider how mental models function in clinical practice, including "fix-it." We observed surgeons who routinely perform high-risk surgery during preoperative discussions with patients. We used qualitative content analysis to explore the use of "fix-it" in 48 audio-recorded conversations. Surgeons used the "fix-it" model for 2 separate purposes during preoperative conversations: (1) as an explanatory tool to facilitate patient understanding of disease and surgery, and (2) as a deliberation framework to assist in decision making. Although surgeons commonly used "fix-it" as an explanatory model, surgeons explicitly discussed limitations of the "fix-it" model as an independent rationale for operating as they deliberated about the value of surgery. Although the use of "fix-it" is familiar for explaining medical information to patients, surgeons recognize that the model can be problematic for determining the value of an operation. Whether patients can transition between understanding how their disease is fixed with surgery to a subsequent deliberation about whether they should have surgery is unclear and may have broader implications for surgical decision making.

    There is considerable interest in improved off-line automated seizure detection methods that will decrease the workload of EEG monitoring units. Subject-specific approaches have been demonstrated to perform better than subject-independent ones. However, for pre-surgical diagnostics, the traditional method of obtaining a priori data to train subject-specific classifiers is not practical. We present an alternative method that works by adapting the threshold of a subject-independent to a specific subject based on feedback from the user.

    subcommittee on Control of Anticoagulation, of the International Society on Thrombosis and Haemostasis has previously published a recommendation for a harmonized definition of major bleeding in non-surgical studies. That definition has been adopted by the European Medicines Agency and is currently used......The definition of major bleeding varies between studies on surgical patients, particularly regarding the criteria for surgical wound-related bleeding. This diversity contributes to the difficulties in comparing data between trials. The Scientific and Standardization Committee (SSC), through its...... in several non-surgical trials. A preliminary proposal for a parallel definition for surgical studies was presented at the 54(th) Annual Meeting of the SSC in Vienna, July 2008. Based on those discussions and further consultations with European and North American surgeons with experience from clinical trials...
