    This paper estimates the risk of bacterial meningitis following surgery between 1996 and 2009 in Denmark. We conducted two retrospective nationwide cohort studies; first by linking notified bacterial meningitis cases to the National Patient Registry to see how many had undergone a surgical procedure; second, we scrutinized notified bacterial meningitis cases to see if the clinician suspected a surgical procedure to be the aetiology. We found that ear, nose and throat surgery had an 11-fold, and neurosurgery a sevenfold, increased risk compared to the reference group in the first 10 days following surgery. Streptococcus pneumoniae was the pathogen most often involved. Operation procedures involving penetration of dura mater was associated with increased risk for post-operative bacterial meningitis. In absolute numbers we found few bacterial meningitis cases after surgery; however, patients undergoing certain surgical procedures are at-risk and should be considered when national vaccination guidelines are revised.

    Routine preoperative testing is discouraged before low-risk surgery because testing does not provide any beneficial effect in terms of patient outcome. However, few studies have assessed the utilization of hospital health care resources in terms of preoperative tests in a real-world setting. Here, we aimed to assess the prevalence and factors associated with preoperative blood tests before low-risk surgery in Japan. In this retrospective observational study, we used the nationwide insurance claims data of Japan. Patients who underwent low-risk surgeries between April 1, 2012, and March 31, 2016, were included. Our primary outcome was the receipt of any preoperative tests within 60 days before an index procedure: complete blood count, basic metabolic panel, coagulation tests, and liver function tests. We performed a descriptive analysis to estimate the proportions of preoperative blood tests, and examined the associations between patient-level and institutional-level factors and preoperative blood tests, using multilevel logistic regression analysis. Interinstitutional variation in the utilization of preoperative tests was summarized using the median odds ratio (OR). The study sample included 59,818 patients (mean [standard deviation] age, 44.0 [11.3] years; 33,574 [56.1%] women) from 9746 institutions. The overall proportion of each test was: complete blood count, 58.7%; metabolic panel, 47.8%; coagulation tests, 36.6%; and liver function tests, 48.5%. The proportion receiving any preoperative tests in the overall sample was 59.5%. Multilevel logistic regression analysis indicated that preoperative blood tests were associated with the Charlson comorbidity index score (score ≥3: adjusted OR, 4.21; 95% confidence interval [CI], 3.69-4.80), anticoagulant use (adjusted OR, 4.12; 95% CI, 2.35-7.22), type of anesthesia (general anesthesia: adjusted OR, 5.69; 95% CI, 4.85-6.68; regional anesthesia: adjusted OR, 3.76; 95% CI, 3.28-4.30), surgical setting (inpatient

    Bariatric surgery represents an appropriate treatment for adolescent severe obesity, but its utilization remains low in this patient population. We studied the impact of race and sex on preoperative characteristics, outcomes, and utilization of adolescent bariatric surgery. Retrospective analysis (2007-2014) of adolescent bariatric surgery using the Bariatric Outcomes Longitudinal Database, a national database that collects bariatric surgical care data. We assessed the relationships between baseline characteristics and outcomes (weight loss and remission of obesity-related conditions [ORCs]). Using the National Health and Nutrition Examination Survey and U.S. census data, we calculated the ratio of severe obesity and bariatric procedures among races and determined the ratio of ratios to assess for disparities. About 1,539 adolescents underwent bariatric surgery. Males had higher preoperative body mass index (BMI; 51.8 ± 10.5 vs. 47.1 ± 8.7, p adolescents underwent bariatric surgery at a higher proportion than blacks and Hispanics (2.5 and 2.3 times higher, respectively). Preoperative characteristics vary according to race and sex. Race and sex do not impact 12-month weight loss or ORC's remission rates. Minority adolescents undergo bariatric surgery at lower-than-expected rates. Copyright © 2017 Society for Adolescent Health and Medicine. Published by Elsevier Inc. All rights reserved.

    Background Kawasaki disease (KD) has been reported in many countries. However, the incidence of KD in Mongolia is not known. This is the first report of incident cases of KD in Mongolia, which were identified using data from 2 nationwide surveys. Methods Two nationwide retrospective surveys were conducted: medical histories were collected from patients aged 0 to 16 years who were hospitalized countrywide between 1996 and 2008. Hospital records for these patients were also reviewed. Nationwide training seminars on KD were conducted before each survey. Results For the nationwide surveys, the participation rates among all hospitals with pediatric wards were 97% and 94%. Inpatient medical histories from 1996 through 2008 were reviewed, and, among children younger than 16 years, 9 patients with KD were investigated. The age of KD patients ranged from 1.4 to 14 years; 7 of 9 patients were male. Six (67%) patients fulfilled all 6 clinical diagnostic criteria; the other 3 (33%) were defined as having KD based on the presence of 5 such criteria. Fever persisting 5 or more days, bilateral conjunctival congestion, and changes of the lips and oral cavity were the most common symptoms, and cervical lymphadenopathy was the least common symptom. Cardiac sequelae developed in 5 of the patients, 4 of whom were older than 10 years. Conclusions The results of these nationwide surveys reveal that KD cases do exist in Mongolia. However, knowledge of KD among Mongolian pediatricians is likely to be poor. Thus, there is a need to augment their understanding to improve management of KD patients. Further studies are crucial to clarify the epidemiologic characteristics of KD in Mongolia. PMID:21691035

    Retrospective cohort study using national health insurance data. To provide a longitudinal reoperation rate after surgery for lumbar herniated intervertebral disc (HIVD) disease, and to compare the reoperation rates of surgical methods. Herniated intervertebral disc disease is the most common cause of lumbar spinal surgery. Despite improved surgical techniques and instrumentation, reoperation cannot be avoided. The reoperation rates were in the range of 6% to 24% in previous studies. A population-based study is less subject to bias; hence, a nationwide longitudinal analysis was warranted. A national health insurance database was used to identify a cohort of patients who underwent first surgery for herniated intervertebral disc disease in 2003 and 18,590 patients were selected. Individual patients were followed for at least 5 years through their encrypted unique resident registration number. The primary endpoint was any type of second lumbar surgery. After adjusting for confounding factors, 5 surgical methods (fusion, laminectomy, open discectomy, endoscopic discectomy, and nucleolysis [including mechanical nucleus decompression]) were compared. Open discectomy was used as the reference method. Open discectomy was the most common procedure (68.9%) followed by endoscopic discectomy (16.1%), laminectomy (7.9%), fusion (3.9%), and nucleolysis (3.2%). The cumulative reoperation rate was 5.4% at 3 months, 7.4% at 1 year, 9% at 2 years, 10.5% at 3 years, 12.1% at 4 years, and 13.4% at 5 years. The reoperation rates were 18.6%, 14.7%, 13.8%, 12.4%, and 11.8% after laminectomy, nucleolysis, open discectomy, endoscopic discectomy, and fusion, respectively. Compared with open discectomy, the reoperation rate was higher after laminectomy at 3 months, whereas the other surgical methods had similar rates. The cumulative reoperation rate after 5 years was 13.4% and half of the reoperations occurred during the first postoperative year. With the exception of laminectomy, the

    This study evaluated the risk of acute myocardial infarction (AMI) and mortality among patients with systemic lupus erythematosus (SLE) in two nationwide retrospective cohort studies. Using Taiwan's National Health Insurance Research Database, we conducted a retrospective cohort study and identified 1207 adults newly diagnosed with SLE in 2000-2004. Non-SLE cohort consisted of 9656 adults without SLE, frequency-matched for age and sex and randomly selected from the same data set. Events of AMI were considered as outcome during the follow-up period between 2000 and 2008. Another nested cohort study of 6900 patients with AMI receiving cardiac surgeries was conducted to analyze the impact of SLE on post-AMI mortality. During the follow-up period, there were 52 newly diagnosed AMI cases. The incidences of AMI for SLE cohort and non-SLE cohort were 2.10 and 0.49 per 1000 person-years, respectively, with an adjusted hazard ratio (HR) of 5.11 (95% confidence interval [CI] 2.63-9.92). For females, the adjusted HR of AMI associated with SLE was as high as 6.28 (95% CI 2.67-14.7). Further analyses in the nested cohort showed that SLE was significantly associated with post-AMI mortality (odds ratio, 2.60; 95% CI 1.09-6.19). Patients with SLE had higher risk of AMI compared with non-SLE control, and this risk was more significant in females. In addition, SLE is an independent risk factor for post-AMI mortality.

    Photodynamic therapy (PDT) is a palliative treatment for malignant biliary obstruction. The objective of this article is to assess the feasibility and safety of this technique. In this nationwide, retrospective study of prospectively collected clinical data, all patients treated with PDT using polyhematoporphyrin in Austria from March 2004 to May 2013 were included. Feasibility, adverse events, stent patency and mortality rates were investigated. Eighty-eight patients (54 male, 34 female, median age 69 years) underwent 150 PDT procedures at seven Austrian referral centers for biliary endoscopy. The predominant underlying disease was Klatskin tumor (79/88). All PDT procedures were feasible without technical issues. Cholangitis was the most frequent adverse event (21/88). Stent patency was 246 days (95% CI 203-289) median and was significantly longer for metal than for plastic stents (269 vs. 62 days, p  < 0.01). The median survival was 12.4 months (95% CI 9.7-14.9 m) calculated from first PDT and 15.6 months (95% CI 12.3-18.7 m) calculated from initial diagnosis. In patients suffering from biliary tract cancer, Cox regression revealed the number of PDT treatment sessions as the only independent predictor of survival at a multivariate analysis ( p  = 0.048). PDT using polyhematoporphyrin was feasible and safe in this nationwide analysis. Survival data suggest a benefit of PDT in this unselected real-life patient population. Prospective trials comparing PDT to other palliative treatments will help to define its role in the management of malignant biliary obstruction. The study is registered at ClinicalTrials.gov number: NCT02504957.

    Purpose: To present, analyze, and discuss results of a nationwide, multicenter, retrospective study on high-dose-rate brachytherapy (HDR-BT) as monotherapy for low-, intermediate-, and high-risk prostate cancer. Methods and Materials: From 1995 through 2013, 524 patients, 73 (14%) with low-risk, 207 (40%) with intermediate-risk, and 244 (47%) with high-risk prostate cancer, were treated with HDR-BT as monotherapy at 5 institutions in Japan. Dose fractionations were 27 Gy/2 fractions for 69 patients (13%), 45.5 Gy/7 fractions for 168 (32%), 49 Gy/7 fractions for 149 (28%), 54 Gy/9 fractions for 130 (25%), and others for 8 (2%). Of these patients, 156 (30%) did not receive androgen deprivation therapy, and 202 patients (39%) did receive androgen deprivation therapy <1 year, 112 (21%) for 1-3 years, and 54 (10%) for >3 years. Median follow-up time was 5.9 years (range, 0.4-18.1 years), with a minimum of 2 years for surviving patients. Results: After 5 years, respective actuarial rates of no biochemical evidence of disease, overall survival, cause-specific survival, and metastasis-free survival for all patients were 92%, 97%, 99%, and 94%. For low/intermediate/high-risk patients, the 5-year no biochemical evidence of disease rates were 95%/94%/89%, the 5-year overall survival rates were 98%/98%/94%, the 5-year cause-specific survival rates were 98%/100%/98%, and the 5-year metastasis-free survival rates were 98%/95%/90%, respectively. The cumulative incidence of late grade 2 to 3 genitourinary toxicity at 5 years was 19%, and that of late grade 3 was 1%. The corresponding incidences of gastrointestinal toxicity were 3% and 0% (0.2%). No grade 4 or 5 of either type of toxicity was detected. Conclusions: The findings of this nationwide, multicenter, retrospective study demonstrate that HDR-BT as monotherapy was safe and effective for all patients with low-, intermediate-, and high-risk prostate cancer.

    Pelvic inflammatory disease (PID) a common infection in women that is associated with significant morbidity and is a major cause of infertility. A clear temporal causal relationship between PID and psychiatric disorders has not been well established. We used a nationwide population-based retrospective cohort study to explore the relationship between PID and the subsequent development of psychiatric disorders. We identified subjects who were newly diagnosed with PID between 1 January 2000 and 31 December 2002 in the Taiwan National Health Insurance Research Database. A comparison cohort was constructed for patients without PID. A total of 21 930 PID and 21 930 matched control patients were observed until diagnosed with psychiatric disorders, or until death, withdrawal from the NHI system, or until 31 December 2009. Adjusted hazard ratio (HR) of bipolar disorder, depressive disorder, anxiety disorder and sleep disorder in subjects with PID were significantly higher (HR: 2.671, 2.173, 2.006 and 2.251, respectively) than that of the controls during the follow-up. PID may increase the risk of subsequent newly diagnosed bipolar disorder, depressive disorder, anxiety disorder and sleep disorder, which will impair life quality. Our findings highlight that clinicians should pay particular attention to psychiatric comorbidities in PID patients.

    Nephrotic syndrome is a common chronic illness encountered during childhood. Infections have been identified as a cause of nephrotic syndrome. The aim of this study was to evaluate the association between enteroviral infection and nephrotic syndrome. A nationwide retrospective cohort study was conducted by analyzing data from the National Health Insurance Research Database in Taiwan. Children aged children were randomly selected as the comparison cohort. The primary endpoint was the occurrence of nephrotic syndrome. This study included 280,087 enterovirus-infected children and 280,085 non-enterovirus-infected children. The mean age of the enterovirus-infected children was 2.38 years, and 53.7% of these children were boys. The overall incidence densities of nephrotic syndrome for enterovirus- and non-enterovirus-infected children were 2.65 and 2.21 per 10,000 person-years, respectively. The enterovirus-infected cohort had a higher cumulative incidence of nephrotic syndrome than did the non-enterovirus-infected cohort (log-rank test, p = 0.01). Multivariable analyses revealed that children with enteroviral infection were significantly associated with an increased risk of nephrotic syndrome compared with those without enteroviral infection (adjusted hazard ratio, 1.20; 95% confidence interval, 1.04-1.39; p = 0.01), particularly in children infected with coxsackievirus. Subgroup analyses revealed that enterovirus-infected girls, children of blue-collar workers, and children without allergies had a higher risk of nephrotic syndrome than did children in the non-enterovirus-infected cohort. This study revealed a significant association between enteroviral infection and nephrotic syndrome. Additional studies elucidating the role and pathogenesis of enterovirus in nephrotic syndrome are warranted.

    Full Text Available Abstract Background Nausea and vomiting is a problem for children after neurosurgery and those requiring posterior fossa procedures appear to have a high incidence. This clinical observation has not been quantified nor have risk factors unique to this group of children been elucidated. Methods A six year retrospective chart audit at two Canadian children's hospitals was conducted. The incidence of nausea and vomiting was extracted. Hierarchical multivariable logistic regression was used to quantify risk and protective factors at 120 hours after surgery and early vs. late vomiting. Results The incidence of vomiting over a ten day postoperative period was 76.7%. Documented vomiting ranged from single events to greater than 20 over the same period. In the final multivariable model: adolescents (age 12 to Conclusion The incidence of vomiting in children after posterior fossa surgery is sufficient to consider all children requiring these procedures to be at high risk for POV. Nausea requires better assessment and documentation.

    Retrospective cohort study of a nationwide database OBJECTIVE.: The primary objective was to summarize the use of surgical methods for lumbar herniated intervertebral disc disease (HIVD) at two different time periods under the national health insurance system (NHIS). The secondary objective was to perform a cost-effectiveness analysis by utilizing incremental cost-effectiveness ratio (ICER). The selection of surgical method for HIVD may or may not be consistent with cost effectiveness under NHIS, but this issue has rarely been analyzed. The data of all patients who underwent surgeries for HIVD in 2003 (n = 17,997) and 2008 (n = 38,264) were retrieved. The surgical methods included open discectomy (OD), fusion surgery, laminectomy and percutaneous endoscopic lumbar discectomy (PELD). The hospitals were classified as tertiary-referral hospitals (≥ 300 beds), medium-sized hospitals (30-300 beds), or clinics (< 30 beds). ICER showed the difference in the mean total cost per 1% decrease in the reoperation probability among surgical methods. The total cost included the costs of the index surgery and the reoperation. In 2008, the number of surgeries increased by 2.13-fold. The number of hospitals increased by 34.75% (731 in 2003 and 985 in 2008). The proportion of medium-sized hospitals increased from 62.79% to 70.86%, but the proportion of surgeries performed at those hospitals increased from 61.31% to 85.08%. The probability of reoperation was highest after laminectomy (10.77%), followed by OD (10.50%), PELD (9.20%) and fusion surgery (7.56%). The ICERs indicated that PELD was cost-effective surgical method. The proportion of OD increased from 71.21% to 84.12%, but that of PELD decreased from 16.68% to 4.57%. The choice of surgical method might not always be consistent with cost-effectiveness strategies, and a high proportion of medium-sized hospitals may be responsible for this change. 4.

    According to the very limited cancer registry, incidence and mortality rates for female breast cancer in China are regarded to be increasing especially in the metropolitan areas. Representative data on the breast cancer profile of Chinese women and its time trend over years are relatively rare. The aims of the current study are to illustrate the breast cancer profile of Chinese women in time span and to explore the current treatment approaches to female breast cancer. This was a hospital-based nation-wide and multi-center retrospective study of female primary breast cancer cases. China was divided into 7 regions according to the geographic distribution; from each region, one tertiary hospital was selected. With the exception of January and February, one month was randomly selected to represent each year from year 1999 to 2008 at every hospital. All inpatient cases within the selected month were reviewed and related information was collected based on the designed case report form (CRF). The Cancer Hospital/Institute, Chinese Academy of Medical Sciences (CICAMS) was the leading hospital in this study. Four-thousand two-hundred and eleven cases were randomly selected from the total pool of 45,200 patients and were included in the analysis. The mean age at diagnosis was 48.7 years (s.d. = 10.5 yrs) and breast cancer peaked in age group 40-49 yrs (38.6%). The most common subtype was infiltrating ductal carcinoma (86.5%). Clinical stage I & II accounted for 60.6% of 4,211 patients. Three-thousand five-hundred and thirty-four cases had estrogen receptor (ER) and progestin receptor (PR) tests, among them, 47.9% were positive for both. Two-thousand eight-hundred and forty-nine cases had human epidermal growth factor receptor 2(HER-2) tests, 25.8% of them were HER-2 positive. Among all treatment options, surgery (96.9% (4,078/4,211)) was predominant, followed by chemotherapy (81.4% (3,428/4,211). Much less patients underwent radiotherapy (22.6% (952/4,211)) and endocrine

    As in other surgical specialties, increasing concern has been expressed worldwide about the shortage of trainees in pediatric surgery training programs. We performed a nationwide survey to investigate the current situation in Germany. An internet-based nationwide survey comprising 36 questions on training conditions in pediatric surgery was linked to the homepage of the German Society of Pediatric Surgery from June to September 2008. Statements on the following aspects were evaluated by responding residents using a scale from 1 (I do not agree at all) to 5 (I fully agree): workplace, cooperation with colleagues, head of the department, cooperation with other specialties, training and research conditions. A median value of 3 indicated an unsatisfactory assessment, with at least 50% of respondents giving an indifferent or negative response. 70 questionnaires were completed. Some of the evaluations revealed problematic areas. In particular, statements regarding working hours revealed dissatisfaction among the responding doctors. The median value accorded the statement "I am satisfied with the current working time regulation" was 2.9. With regard to departmental heads, some criticisms were directed against a perceived lack of soft skills. According to the respondents, their involvement in decision-making processes was insufficient ("We are involved in decision-making processes affecting our working conditions" - median value 2.4). Residents were also dissatisfied with the feedback they received for their work ("I get enough feedback regarding my achievement" - median value 2.6). Another problem area was career development ("I will finish my specialist training in time" - median value 2.9). However, these points did not affect overall satisfaction. Trainee satisfaction with regulations on working hours is low. Despite a general satisfaction with all fields appraised, improvements in various individual areas, e. g., the attitude of departmental heads and strategies of

    The literature on transverse colonic cancer resection is sparse. The optimal surgical approach for this disease is thus unknown. This study aimed to examine laparoscopic versus open surgery for transverse colonic cancer. This study was a nationwide, retrospective cohort study of all patients registered with a transverse colonic cancer in Denmark between 2010 and 2013. Data were obtained from the Danish Colorectal Cancer Group, the Danish Pathology Registry, Danish National Patient Registry, and patients' records. Main outcome measures were surgical resection plane, lymph node yield, and long-term cancer recurrence and survival. In total, 357 patients were included. Non-mesocolic resection was more frequent with laparoscopic compared with open resection (adjusted odds ratio 2.44, 95% CI 1.29-4.60, P = 0.006). Median number of harvested lymph nodes was higher after open compared with laparoscopic resection (22 versus 19, P = 0.03). Non-mesocolic resection (adjusted hazard ratio 2.45, 95% CI 1.25-4.79, P = 0.01) and increasing tumor stage (P Cancer recurrence was significantly associated with an increased risk of mortality (adjusted hazard ratio 4.32, 95% CI 2.75-6.79, P transverse colonic cancers led to similar long-term results compared with open resection.

    Full Text Available This was a retrospective review of a consecutive series of patients with spinal disease in year 2000, who underwent posterior fusion and instrumentation with Harrington distraction and Cotrel-Dobousset system to evaluate causes of hardware failure. Many cases of clinical failure has been observed in spinal instrumentation used in spinal disorder like spondylolisthesis, fractures, deformities, … . Thirty six cases that were operated because of spinal disorders like spondylolisthesis, fractures, deformities, …, were included in this study. Seventeen of this cases had breakage of device. Factors like age at surgery, type of instrumentation, angles before and after surgery and …, were compared in two groups of patients. The most common instrument breakage was pedicle screw breakage. Pseudoarthrosis was the main factor that was presented in failure group (P value<0.001. Other important causes were, age of patient at surgery (P value=0.04, pedicle screw placement off center in the sagittal or coronal plane of the pedicle (P value=0.04. Instrumentation loads increased significantly as a direct result of variations in surgical technique that produce pseudoarthrosis, pedicle screw placement off center in the sagittal plane of the pedicle, or using less than 6 mm diameter screw. This factor can be prevented with meticulous surgical technique and using proper devices.

    Lumbar spinal stenosis is one of the most common degenerative spine diseases. Surgical options are largely divided into decompression only and decompression with arthrodesis. Recent randomized trials showed that surgery was more effective than nonoperative treatment for carefully selected patients with lumbar stenosis. However, some patients require reoperation because of complications, failure of bony fusion, persistent pain, or progressive degenerative changes, such as adjacent segment disease. In a previous population-based study, the 10-year reoperation rate was 17%, and fusion surgery was performed in 10% of patients. Recently, the lumbar fusion surgery rate has doubled, and a substantial portion of the reoperations are associated with a fusion procedure. With the change in surgical trends, the longitudinal surgical outcomes of these trends need to be reevaluated. To provide the longitudinal reoperation rate after surgery for spinal stenosis and to compare the reoperation rates between decompression and fusion surgeries. Retrospective cohort study using national health insurance data. A cohort of patients who underwent initial surgery for lumbar stenosis without spondylolisthesis in 2003. The primary end point was any type of second lumbar surgery. Cox proportional hazards regression modeling was used to compare the adjusted reoperation rates between decompression and fusion surgeries. A national health insurance database was used to identify a cohort of patients who underwent an initial surgery for lumbar stenosis without spondylolisthesis in 2003; a total of 11,027 patients were selected. Individual patients were followed for at least 5 years through their encrypted unique resident registration number. After adjusting for confounding factors, the reoperation rates for decompression and fusion surgery were compared. Fusion surgery was performed in 20% of patients. The cumulative reoperation rate was 4.7% at 3 months, 7.2% at 1 year, 9.4% at 2 years, 11.2% at

    The primary aim was to examine exposure-response relationships between cumulative occupational shoulder exposures and surgery for subacromial impingement syndrome (SIS), and to compare sex-specific exposure-response relationships. The secondary aim was to examine the time window of relevant exposures. We conducted a nationwide register study of all persons born in Denmark (1933-1977), who had at least 5 years of full-time employment. In the follow-up period (2003-2008), we identified first-time events of surgery for SIS. Cumulative exposure estimates for a 10-year exposure time window with a 1-year lag time were obtained by linking occupational codes with a job exposure matrix. The exposure estimates were expressed as, for example, arm-elevation-years in accordance with the pack-year concept of tobacco consumption. We used a multivariable logistic regression technique equivalent to discrete survival analysis. The adjusted OR (ORadj) increased to a maximum of 2.1 for arm-elevation-years, repetition-years and force-years, and to 1.5 for hand-arm-vibration-years. Sex-specific exposure-response relationships were similar for men and women, when assessed using a relative risk scale. The ORadj increased gradually with the number of years contributing to the cumulative exposure estimates. The excess fraction was 24%. Cumulative occupational shoulder exposures carried an increase in risk of surgery for SIS with similar exposure-response curves for men and women. The risk of surgery for SIS increased gradually, when the period of exposure assessment was extended. In the general working population, a substantial fraction of all first-time operations for SIS could be related to occupational exposures. Published by the BMJ Publishing Group Limited.

    Bariatric surgery is a well-accepted procedure for severe and massive obesity management. We aimed to determine trends, geographical variations, and factors influencing bariatric surgery and the choice of procedure in France in a large observational study.The Health Insurance Fund for Salaried Workers (Caisse National Assurance Maladie Travailleurs Salariés) covers about 86% of the French population. The Système National d'Information Inter-régimes de l'Assurance Maladie database contains individualized and anonymized patient data on all reimbursements for healthcare expenditure. All types of primary bariatric procedures (Roux-en-Y gastric bypass [RYGB] or omega loop, adjustable gastric banding [AGB], or longitudinal sleeve gastrectomy [LSG]) performed during 2011 to 2013 were systematically recorded. Surgical techniques performed by region of residence and age-range relative risks with 95% confidence intervals of undergoing LSG or RYGB versus AGB were computed.In 2013, LSG was performed more frequently than RYGB and AGB (57% vs 31% and 13%, respectively). A total of 41,648 patients underwent a bariatric procedure; they were predominantly female (82%) with a mean (±standard deviation) age of 40 (±12) years and a body mass index ≥40 kg/m for 68% of them. A total of 114 procedures were performed in patients younger than 18 years and 2381 procedures were performed in patients aged 60 years and older. Beneficiaries of the French universal health insurance coverage for low-income patients were more likely to undergo surgery than the general population. Large nationwide variations were observed in the type choice of bariatric surgical procedures. Significant positive predictors for undergoing RYGB compared to those for undergoing AGB were as follows: referral to a center performing a large number of surgeries or to a public hospital, older age, female gender, body mass index ≥50 kg/m, and treatment for obstructive sleep apnea syndrome, diabetes, or

    Pelvic inflammatory disease (PID) is characterized by infection and inflammation of the upper genital tract in women and is associated with health sequelae. We used a nationwide population-based retrospective cohort study to explore the relationship between PID and the subsequent development of gynecological cancers including ovarian, breast or uterine cancer. We identified subjects diagnosed with PID between January 1 st , 2000 and December 31 st , 2002 in the Taiwan National Health Insurance Research Database. A comparison cohort constructed for patients without PID were matched according to age and sex. All PID patients and control groups were observed until diagnosed with ovarian, breast or uterine cancer, or until death, withdrawal from the NHI system, or until December 31 st , 2009. The PID cohort consisted of 32,268 patients, and an equal number of matched controls without PID. The adjusted hazard ratio (HR) of ovarian, breast or uterine cancer in subjects with PID were: HR 1.326 (95 % confidence interval: 0.775-2.269), HR: 1.039 (95 % confidence interval: 0.862-1.252), and HR: 1.439 (95 % confidence interval: 0.853-2.426) respectively in comparison with controls during follow-up. This large nationwide population-based cohort study suggests that there is no increased risk for ovarian, breast or uterine cancer among women who have PID compared to a matching population.

    Full Text Available Background: Surgical treatment of adult lumbar spinal disorders is associated with a substantial risk of intraoperative and perioperative complications. There is no clearly defined medical literature on complication in lumbar spine surgery. Purpose of the study is to retrospectively evaluate intraoperative and perioperative complications who underwent various lumbar surgical procedures and to study the possible predisposing role of advanced age in increasing this rate. Materials and Methods: From 2007 to 2011 the number and type of complications were recorded and both univariate, (considering the patients′ age and a multivariate statistical analysis was conducted in order to establish a possible predisposing role. 133 were lumbar disc hernia treated with microdiscetomy, 88 were lumbar stenosis, treated in 36 cases with only decompression, 52 with decompression and instrumentation with a maximum of 2 levels. 26 patients showed a lumbar fracture treated with percutaneous or open screw fixation. 12 showed a scoliotic or kyphotic deformity treated with decompression, fusion and osteotomies with a maximum of 7.3 levels of fusion (range 5-14. 70 were spondylolisthesis treated with 1 or more level of fusion. In 34 cases a fusion till S1 was performed. Results: Of the 338 patients who underwent surgery, 55 showed one or more complications. Type of surgical treatment ( P = 0.004, open surgical approach (open P = 0.001 and operative time ( P = 0.001 increased the relative risk (RR of complication occurrence of 2.3, 3.8 and 5.1 respectively. Major complications are more often seen in complex surgical treatment for severe deformities, in revision surgery and in anterior approaches with an occurrence of 58.3%. Age greater than 65 years, despite an increased RR of perioperative complications (1.5, does not represent a predisposing risk factor to complications ( P = 0.006. Conclusion: Surgical decision-making and exclusion of patients is not justified only

    Actuarial analysis of stoma complications (problematic stomas) is lacking. The objectives of this audit were: to identify the incidence of stoma complications within the UK; to highlight any dissimilarity of incidence from centre to centre; to ascertain if the height of the stoma (distance of stoma lumen from the skin) at the time of fashioning is a predisposing factor to problems; and finally to initiate much needed research. Commencing 1st January 2005, stoma care services nationwide (256) were invited to audit prospectively their next 50 enteric stomas or for a period of 1 year which ever came first. The definition of a problematic stoma being one, which needed one or more accessories to keep the patient clean and dry for a minimum period of 24 h. The incident is to have happened within 3 weeks of surgery. Factors taken into account were: type of stoma, height of stoma within 48 h of surgery; emergency or elective procedure, problem identified, BMI, gender and underlying diagnosis of the patient. The identities of the participating centres are confidential. Of the 256 hospital-based stoma care services within the UK, 93 (36%) participated. A total of 3970 stomas were recorded, of which 1329 (34%) were identified as problematic. Sixty-two centres reported 45-50 stomas with a range of complications 6-96%. The loop ileostomy was found to be the stoma which causes most problems. A stoma of stomas formed, but have significantly fewer problems and there is no significant difference between underlying diagnoses. The stoma height, stoma type and gender of the patient are significant risk factors identified in this audit. The BMI of patient did not affect the outcome. Patients undergoing an emergency procedure are more likely to have a problematic stoma. The significant variation of complications from centre to centre indicates surgical technique as being the key factor in stoma formation and subsequent quality of life for the patient.

    Traditionally regarded as a disease of the elderly, the incidence of diverticulitis of the colon has been on the rise, especially in younger cohorts. These patients have been found to experience a more aggressive disease course with more frequent hospitalization and greater need for surgical intervention. To characterize factors that portend a poor prognosis in patients diagnosed with diverticulitis; in particular, to evaluate the role of demographic variables on disease course. Using the Canadian Institute for Health Information Discharge Abstract Databases, readmission rates, length of stay, colectomy rates and mortality rates in patients hospitalized for diverticulitis were examined. Data were stratified according to age, sex and comorbidity (as defined by the Charlson index). In the cohort ≤30 years of age, a clear male predominance was apparent. Colectomy rate in the index admission, stratified according to age, demonstrated a J-shaped curve, with the highest rate in patients ≤30 years of age (adjusted OR 2.3 [95% CI 1.62 to 3.27]) compared with the 31 to 40 years of age group. In-hospital mortality increased with age. Cumulative rates of readmission at six and 12 months were 6.8% and 8.8%, respectively. In the present nationwide cohort study, younger patients (specifically those ≤30 years of age) were at highest risk for colectomy during their index admission for diverticulitis. It is unclear whether this observation was due to more virulent disease among younger patients, or surgeon and patient preferences.

    Periodontitis is one of the most prevalent oral diseases. In this study, we probed the nationwide registered database to assess the time trends of prevalence of periodontitis in Taiwan.A retrospective study was conducted to analyze the registered database compiled by the National Health Insurance provided by the Department of Health, Taiwan, from 1997 to December 2013.We found that the prevalence of periodontitis significantly increased from 11.5% in 1997 to 19.59% in 2013 (P for trend periodontitis from 1997 to 2013 was 54.46 ± 14.47 and 45.51 ± 16.58 years old, respectively. The proportion of individuals with periodontitis in age group >65 years old decreased markedly. The proportion of individuals with periodontitis in age groups periodontitis (male: RR, 67.42, 95% confidence interval [CI], 17.04-266.76; female: RR, 65.85, 95% CI, 16.70-259.70). Both male and female groups showed the similar age-effect pattern in the cross-sectional age curve from age-period-cohort model. There was an upturn with advancing age up to 40 to 50 years old and then a downward trend in both genders. Population dwelling in suburban area (RR, 0.95; 95% CI, 0.94-0.97) and rural area (RR, 0.97; 95% CI, 0.95-0.99) had the lower risk of periodontitis than those who lived in urban area. The higher income group revealed the higher risk of periodontitis compared with lower income group (RR, 1.20; 95% CI, 1.18-1.23).The prevalence of periodontitis significantly increased in Taiwan over past 17 years. The mean age with periodontitis was shown in a decreased pattern. The use of a nationwide population-based database could provide sufficient sample size, generalizability, and statistical power to assess the periodontal status in Taiwan.

    There are limited data on the risk of non-melanoma skin cancer (NMSC) and melanoma skin cancer (MSC) among thiopurine-treated patients with ulcerative colitis (UC). Our aim was to investigate the risk while on, by cumulative years, and after stopping thiopurine therapy. Nationwide data were obtained from the Veterans Affairs (VA) health-care system during 2001-2011. We performed a retrospective cohort study evaluating patients with UC. Cox regression was used to investigate the association between thiopurines use and time to NMSC while adjusting for demographics, ultraviolet radiation exposure, and VA visiting frequency. A matched nested case-control study was conducted to investigate the association between thiopurine use and MSC. We included 14,527 patients with UC in the analysis, with a median follow-up of 8.1 years. A total of 3,346 (23%) patients used thiopurines for a median duration of 1.6 years. We identified 421 NMSC and 45 MSC cases. The adjusted hazard ratios of developing NMSC while on and after stopping thiopurines were 2.1 (P<0.0001) and 0.7 (P=0.07), respectively, as compared with unexposed patients. The incidence rate of NMSC among those who never used thiopurines was 3.7 compared with 5.8, 7.9, 8.3, 7.8, and 13.6 per 1,000 person-years for the 1st, 2nd, 3th, 4th, and 5th year of thiopurine use, respectively. No statistically significant association was observed between thiopurine use and MSC, odds ratio 0.8 (P=0.6). In this predominantly white male nationwide cohort, there was a twofold increase in the risk of NMSC while on thiopurines. The incidence rate of NMSC significantly increased with subsequent years of cumulative exposure to thiopurines. Stopping thiopurines reduced the risk of NMSC to pre-exposure levels irrespective of the prior exposure duration.

    Since its introduction in 1997, robotic surgery has overcome many limitations, including setup costs and surgeon training. The use of robotics in general surgery remains unknown. This study evaluates robotic-assisted procedures in general surgery by comparing characteristics with its nonrobotic (laparoscopic and open) counterparts. Weighted Healthcare Cost and Utilization Project Nationwide Inpatient Sample data (2008, 2009) were used to identify the top 12 procedures for robotic general surgery. Robotic cases were identified by Current Procedural Terminology codes 17.41 and 17.42. Procedures were grouped: esophagogastric, colorectal, adrenalectomy, lysis of adhesion, and cholecystectomy. Analyses were descriptive, t tests, χ(2)s, and logistic regression. Charges and length of stay were adjusted for gender, age, race, payer, hospital bed size, hospital location, hospital region, median household income, Charlson score, and procedure type. There were 1,389,235 (97.4%) nonrobotic and 37,270 (2.6%) robotic cases. Robotic cases increased from 0.8 per cent (2008) to 4.3 per cent (2009, P surgery had significantly shorter lengths of stay (4.9 days) than open surgery (6.1 days) and lower charges (median $30,540) than laparoscopic ($34,537) and open ($46,704) surgery. Fewer complications were seen in robotic-assisted colorectal, adrenalectomy and lysis of adhesion; however, robotic cholecystectomy and esophagogastric procedures had higher complications than nonrobotic surgery (P surgery had a lower mortality rate (0.097%) than nonrobotic surgeries per 10,000 procedures (laparoscopic 0.48%, open 0.92%; P surgery is generally considered a prohibitive factor. In the present study, when overall cost was considered, including length of stay, robotic surgery appeared to be cost-effective and as safe as nonrobotic surgery except in cholecystectomy and esophagogastric procedures. Further study is needed to fully understand the long-term implications of this new technology.

    The purpose of the present study was to compare the perioperative and oncologic outcomes between laparoscopic surgery and open surgery for transverse colon cancer. We conducted a retrospective review of patients who underwent surgery for transverse colon cancer at six Hallym University-affiliated hospitals between January 2005 and June 2015. The perioperative outcomes and oncologic outcomes were compared between laparoscopic and open surgery. Of 226 patients with transverse colon cancer, 103 underwent laparoscopic surgery and 123 underwent open surgery. There were no differences in the patient characteristics between the two groups. Regarding perioperative outcomes, the operation time was significantly longer in the laparoscopic group than in the open group (267.3 vs 172.7 minutes, Ptransverse colon cancer. Therefore, laparoscopic surgery offers a safe alternative to open surgery in patients with transverse colon cancer.

    Laparoscopic surgery is a surgical approach with proven advantages in the contemporary treatment of gynaecological diseases. It is applied with proven results in oncologic patients in order to respect certain rules. Mini-invasive approach has less complication and therefore is widely recommended. In this respect, the constantly increasing interest in this surgery and additional training and education. Risk factors must be taken into consideration and patients should be informed about possible complications during surgery.

    There is no study about cervical herniated intervertebral disc (cervical HIVD) in physicians in the literature; therefore, we conceived a retrospective nationwide, population-based cohort study to elucidate the topic. We identified 26,038 physicians, 33,057 non-physician healthcare providers (HCPs), and identical numbers of non-HCP references (i.e., general population). All cohorts matched a 1:1 ratio with age and gender, and each were chosen from the Taiwan National Health Insurance Research Database (NHIRD). We compared cervical HIVD risk among physicians, nonphysician HCPs, and non-HCP references and performed a follow-up between 2007 and 2011. We also made comparisons among physician specialists. Both physicians and nonphysician HCPs had higher cervical HIVD risk than non-HCP references (odds ratio [OR]: 1.356; 95% confidence interval (CI): 1.162-1.582; OR: 1.383; 95% CI: 1.191-1.605, respectively). There was no significant difference of cervical HIVD risk between physicians and nonphysician HCPs. In the comparison among physician specialists, orthopedists had a higher cervical HIVD risk than other specialists, but the difference was not statistically significant (adjusted OR: 1.547; 95% CI: 0.782-3.061). Physicians are at higher cervical HIVD risk than the general population. Because unknown confounders could exist, further prospective studies are needed to identify possible causation.

    The purpose of this study was to evaluate the risk of adverse maternal outcomes associated with trial of labor (TOL) after cesarean during subsequent pregnancies in the low-risk population. We conducted a retrospective cohort study using the Nationwide Inpatient Sample and ICD-9 diagnostic and procedure codes from the years 2003 to 2011. A cohort of low-risk pregnant women with a history of previous cesarean delivery were identified and separated into two groups: TOL and no TOL. Logistic regression analysis was used to calculate odds ratios (ORs) comparing adverse maternal outcomes between these two groups. Out of 7 290 474 registered deliveries, there were 685 137 low-risk women who met inclusion criteria. Of these women, 144 066 (21.0%) underwent a TOL, with rates remaining steady over the course of our study. The TOL group was at increased risk of overall morbidity (OR 1.74, 95% confidence interval (CI), 1.66-1.79), most notably uterine rupture (OR 22.52, 95% CI, 19.35-26.20, Pcesarean delivery.

    Routine preoperative pulmonary function tests (PFTs) are not recommended prior to low-risk surgery because their prognostic value is limited. However, only a few studies have assessed the utilization of healthcare resources regarding preoperative PFTs in a real-world setting. Here, we aimed to assess the prevalence and determinant factors of preoperative PFTs before low-risk surgery in Japan. In this retrospective cohort study, we used the nationwide insurance claims databases. Patients who underwent low-risk surgeries under general anesthesia between April 1, 2012, and March 31, 2016, were included. The primary outcome was the receipt of PFTs within 60 days before an index surgery. We performed descriptive analyses to estimate the rates of preoperative PFTs annually starting in 2012, and examined the associations between patient- and institutional-level factors and preoperative PFTs using multilevel logistic regression analyses. The cohort included 9495 procedures (8866 patients) at 1487 institutions. Preoperative PFTs were conducted before 71.8% of the procedures. The temporal trend of preoperative PFTs remained constant from 72.4% in 2012 to 72.2% in 2015. Multilevel regression analysis revealed that preoperative PFTs were associated with older age, number of beds at a medical facility, and inpatient procedures. The median institutional-specific proportion of PFTs was 75.0% (interquartile range, 14.3-100%) with wide inter-institutional variation. Our analysis found that preoperative PFTs were performed before 72% of low-risk surgeries under general anesthesia. Apart from age, preoperative PFTs were determined primarily by non-medical factors. Additionally, we observed substantial institutional variation in the use of preoperative PFTs.

    Infections by carbapenem-resistant Klebsiella pneumoniae (CRKp) represent a challenging problem after SCT. A retrospective survey (January 2010 to July 2013) involving 52 Italian centers was performed to assess the epidemiology and the prognostic factors of CRKp infections in auto- and allo-SCT. Cases of CRKp infection were reported in 53.4% of centers. CRKp infections were documented in 25 auto-SCTs and 87 allo-SCTs, with an incidence of 0.4% (from 0.1% in 2010 to 0.7% in 2013) and 2% (from 0.4% in 2010 to 2.9% in 2013), respectively. A CRKp colonization documented before or after transplant was followed by an infection in 25.8% of auto-SCT and 39.2% of allo-SCT patients. The infection-related mortality rates were 16% and 64.4%, respectively. A pre-transplant CRKp infection (hazard ratio (HR) 0.33, 95% confidence intervals (CIs) 0.15-0.74; P=0.007) and a not CRKp-targeted first-line treatment (HR 2.67, 95% CI 1.43-4.99; P=0.002) were independent factors associated with an increased mortality in allo-SCT patients who developed a CRKp infection. Our study shows challenging findings of CRKp infections in SCT patients in Italy particularly after allo-SCT. The detection of carriers and the definition of early therapeutic strategies represent critical aspects of the management of CRKp infections after SCT.

    Studies have reported an association between asthma and oral diseases, including periodontal diseases. The aim of this retrospective study is to investigate risk of periodontal diseases for patients with asthma. Using the claims data of National Health Insurance of Taiwan and patients without a history of periodontal diseases, 19,206 asthmatic patients, who were newly diagnosed from 2000 through 2010, were identified. For each case, four comparison individuals without history of asthma and periodontal disease were randomly selected from the general population and frequency matched (categorical matched) by sex, age, and year of diagnosis (n = 76,824). Both cohorts were followed to the end of 2011 to monitor occurrence of periodontal diseases. Adjusted hazard ratios (aHRs) of periodontal disease were estimated using Cox proportional hazards regression analysis. Overall incidence of periodontal diseases was 1.18-fold greater in the asthma cohort than in the comparison cohort (P periodontal diseases compared with those with a mean of less than one visit. Patients with at least three admissions annually also had a similar aHR (51.8) for periodontal disease. In addition, asthmatic patients on inhaled corticosteroid (ICS) therapy had greater aHRs than non-users (aHR = 1.12; 95% CI = 1.03 to 1.23). In the studied population, asthmatic patients are at an elevated risk of developing periodontal diseases. The risk is much greater for those with emergency medical demands or hospital admissions and those on ICS treatment.

    The cytogenetic and molecular data is recognized as the most valuable prognostic factor in acute myeloid leukemia (AML). Our aim was to systemically analyze the cytogenetics of Korean AML patients and to compare the cytogenetic profiles of various races to identify possible geographic heterogeneity. We retrospectively reviewed medical records of 2806 AML patients diagnosed at 11 tertiary teaching hospitals in Korea between January 2007 and December 2011. The most common recurrent chromosomal abnormality was t(8;21) (8.8 %, 238/2717), but t(15;17) showed an almost same number (8.6 %,235/2717). Among de novo AML, the most frequent aberrations were t(15;17), observed in 229 (10.7 %). The most common French-American-British (FAB) classification type was M2 (32.2 %), and recurrent cytogenetic abnormalities correlated with the FAB subtypes. Among 283 secondary AML cases, myelodysplastic syndrome was the most common predisposing factor. About 67.1 % of the secondary AML cases were associated with chromosomal aberrations, and chromosome 7 abnormalities (n = 45, 15.9 %) were most common. The incidence of FLT3 internal tandem duplication mutation was relatively low at 15 %. Our study reports certain similarities and differences in comparison to previous reports. Such discrepancies call for extensive epidemiological studies to clarify the role of genetic as well as geographic heterogeneity in the pathogenesis of AML.

    Oral leukoplakia (OL) is one of the clinically diagnosed oral potentially malignant disorders (OPMDs) with an increased risk of oral cancer development. In this study, we investigated the malignant transformation of OL in Taiwanese population. A retrospective cohort study was analyzed from Taiwan's National Health Insurance Research Database. A comparison cohort was randomly frequency-matched with the OL cohort according to age, sex, and index year. Oral submucous fibrosis (OSF) and oral lichen planus (OLP) were further stratified to evaluate the possible synergistic effects for OL-associated malignant transformation. In this cohort, 102 (5.374%) of 1898 OL patients were observed to transform into oral cancer. The malignant transformation rate was 26.40-fold in the OL cohort than in the comparison cohort after adjustment (95% confidence intervals 18.46-37.77). To further stratify with OSF and OLP, OL with OSF (58.38; 95% confidence intervals 34.61-98.50) and OL with OLP (36.88; 95% confidence intervals 8.90-152.78) had higher risk of malignant transformation rate than OL alone (27.01; 95% confidence intervals 18.91-38.59). The Kaplan-Meier plot revealed the free of malignant transformation rate was significant over the 13 years follow-up period (log-rank test, p transformation than those without OL. In addition, both OSF and OLP could enhance malignant transformation in patients with OL. However, further studies are required to identify the histopathological and clinical parameters in the pathogenesis of malignant transformation among OPMDs. Copyright © 2018.

    Bell's palsy and anxiety disorders share numerous risk factors (e.g., immune response, ischemia, and psychological stress). However, there have been no studies on the bidirectional temporal association between the two illnesses. In this study, we used the Taiwan National Health Insurance Research Database (NHIRD) to test the bidirectional association between Bell's palsy and anxiety disorders. We hypothesized that patients with Bell's palsy would have an increased risk of subsequent anxiety disorders later in life and that, conversely, those with anxiety disorders would have an increased likelihood of developing Bell's palsy later in life. We conducted two retrospective cohort studies using Taiwan's National Health Insurance Research Database (NHIRD). Study 1 included 8070 patients diagnosed with anxiety disorders and 32,280 controls without anxiety disorders who were matched with sex, age, and enrollment date to analyze the following risk of Bell's palsy among both groups. Study 2 included 4980 patients with Bell's palsy and 19,920 controls without Bell's palsy who were matched with sex, age, and enrollment date to analyze the following risk of anxiety disorders among both groups. The patient records selected for the studies were dated between January 1, 2000, and December 31, 2004. All subjects were observed until their outcomes of interest, death or December 31, 2009. After adjustment for age, sex, comorbidities, urbanization, and income, the hazard ratio (HR) for patients with anxiety disorders to contract Bell's palsy was 1.53 (95% CI, 1.21-1.94, PBell's palsy to develop an anxiety disorder was 1.59 (95% CI, 1.23-2.06, PBell's palsy and anxiety disorders. After one of these conditions develops, the morbidity rate for the other significantly increases. Additional studies are required to determine whether these two conditions share the same pathogenic mechanisms, and whether successfully treating one will reduce the morbidity rate for the other.

    To investigate the risk of epilepsy in stroke patients receiving and not receiving acupuncture treatment. Retrospective cohort study. This study was based on Taiwan's National Health Insurance Research Database that included information on stroke patients hospitalised between 1 January 2000 and 31 December 2004. We identified 42 040 patients hospitalised with newly diagnosed stroke who were aged 20 years and above. We compared incident epilepsy during the follow-up period until the end of 2009 in stroke patients who were and were not receiving acupuncture. The adjusted HRs and 95% CIs of epilepsy associated with acupuncture were calculated using multivariate Cox proportional hazard regression. Stroke patients who received acupuncture treatment (9.8 per 1000 person-years) experienced a reduced incidence of epilepsy compared to those who did not receive acupuncture treatment (11.5 per 1000 person-years), with an HR of 0.74 (95% CI 0.68 to 0.80) after adjustment for sociodemographic factors and coexisting medical conditions. Acupuncture treatment was associated with a decreased risk of epilepsy, particularly among stroke patients aged 20-69 years. The log-rank test probability curve indicated that stroke patients receiving acupuncture treatment had a reduced probability of epilepsy compared with individuals who did not receive acupuncture treatment during the follow-up period (pacupuncture treatment had a reduced risk of epilepsy compared with those not receiving acupuncture treatment. However, the protective effects associated with acupuncture treatment require further validation in prospective cohort studies. Published by the BMJ Publishing Group Limited.

    Increasing evidence suggests that certain types of cancers are more common in people with diabetes mellitus (DM). This study aimed to investigate the risk of skin cancer in patients with DM in Taiwan. In this retrospective cohort study using data from the Taiwan Longitudinal Health Insurance Research Database, the risk of developing overall skin cancer, including nonmelanoma skin cancer (NMSC) and melanoma, was compared by Poisson regression analysis and Cox regression analysis between the DM and non-DM cohorts. The DM cohort with newly diagnosed DM (n = 41,898) and a non-DM cohort were one-to-one matched by age, sex, index date, and comorbidities (coronary artery disease, hyperlipidemia, hypertension, chronic kidney disease, chronic obstructive pulmonary disease, and obesity). Compared with non-DM cohort statistically, for the people with DM aged ≥60 years, the incidence rates of overall skin cancer and NMSC were significantly higher (overall: DM/non-DM: number [n] = 99/76, incidence rate ratio [IRR] = 1.44, P = 0.02; NMSC: DM/non-DM: n = 94/66, IRR = 1.57, P = 0.005). By Cox regression analysis, the risk of developing overall skin cancer or NMSC was significantly higher after adjusting for sex, comorbidities, and overall diseases with immunosuppression status (overall: adjusted hazard ratio [AHR] = 1.46, P = 0.01; NMSC: AHR = 1.6, P = 0.003). Other significant risk factors were older males for skin cancer (overall: AHR = 1.68, P = 0.001; NMSC: AHR = 1.59, P = 0.004; melanoma: AHR = 3.25, P = 0.04), chronic obstructive pulmonary disease for NMSC (AHR = 1.44, P = 0.04), and coronary artery disease for melanoma (AHR = 4.22, P = 0.01). The risk of developing melanoma was lower in the DM cohort than in the non-DM cohort, but without significance (AHR = 0.56, P = 0.28; DM/non-DM: n = 5/10). The incidence rate and risk of developing overall skin cancer, including NMSC, was significantly higher in older adults with DM. Other significant risk factors for older adults

    Outcome after intrauterine transfusions due to severe hemolytic disease of the fetus and newborn. Nationwide population-based retrospective cohort study. All women treated with intrauterine transfusions for hemolytic disease of the fetus and newborn in Finland in 2003-2012. 339 intrauterine transfusions, performed in 104 pregnancies of 84 women. Information on antenatal screening of red cell antibodies and red cell units issued for intrauterine transfusion was obtained from the Finnish Red Cross Blood Service database, and obstetric and neonatal data from hospital records. Procedure-related complications, perinatal mortality, neonatal morbidity. Overall survival was 94.2% (95% confidence interval 89.7-98.7). There were four fetal and two neonatal deaths. Procedure-related fetal loss rate was 1.2% (95% confidence interval 0.04-2.4) per procedure and 3.8% (95% confidence interval 0.1-7.5) per pregnancy. Of the four procedure-related losses, three were due to technically difficult intrauterine transfusions causing infection and preterm birth. Of the live born infants, 19% (95% confidence interval 11.3-26.7) were born before 32 weeks' gestation. The incidence of severe neonatal morbidity (respiratory distress syndrome, severe cerebral injury, sepsis) was 22.2% (95% confidence interval 13.4-30.2). Poor outcome (death, severe neonatal morbidity) was negatively associated with gestational age at first transfusion (p = 0.001) and at birth (p = 0.00006). Follow-up of the infants was too incomplete to assess the neurodevelopmental outcome. Although overall survival is comparable with previous studies, our concern is procedure-related infections and preterm births. Close collaboration between the university hospitals is needed to ensure timely treatment, operator skills and systematic follow-up of the children. © 2015 Nordic Federation of Societies of Obstetrics and Gynecology.

    The objective of this study was to examine the association between obesity and all-cause mortality, length of stay and hospital cost among patients with sepsis 20 years of age or older. It was a retrospective cohort study. The dataset was the Nationwide Inpatient Sample 2011, the largest publicly available all-payer inpatient care database in the United States. Hospitalizations of sepsis patients 20 years of age or older were included. All 25 primary and secondary diagnosis fields were screened to identify patients with sepsis using International Classification of Diseases, Ninth Revision, Clinical Modification codes. Obesity was the exposure of interest. It was one of the 29 standardized Elixhauser comorbidity measures and readily available in the dataset as a dichotomized variable. The outcome measures were all-cause in-hospital death, length of stay and hospital cost. After weighting, our sample projected to a population size of 1,763,000, providing an approximation for the number of hospital discharges of all sepsis patients 20 years of age or older in the US in 2011. The overall all-cause mortality rate was 14.8%, the median hospital length of stay was 7 days and the median hospital cost was $15,917. After adjustment, the all-cause mortality was lower (adjusted OR = 0.84; 95% CI = 0.81 to 0.88); the average hospital length of stay was longer (adjusted difference = 0.65 day; 95% CI = 0.44 to 0.86) and the hospital cost per stay was higher (adjusted difference = $2,927; 95% CI = $1,606 to $4,247) for obese sepsis patients as compared to non-obese ones. With this large and nationally representative sample of over 1,000 hospitals in the US, we found that obesity was significantly associated with a 16% decrease in the odds of dying among hospitalized sepsis patients; however it was also associated with greater duration and cost of hospitalization.

    Recent clinical studies have shown that anticoagulant therapy might be effective only in specific at-risk subgroups of patients with sepsis and coagulation dysfunction. The definition of sepsis was recently modified, and as such, old scoring systems may no longer be appropriate for the diagnosis of sepsis-associated coagulopathy. The aim of this study was to evaluate prognostic factors in patients diagnosed with sepsis and coagulopathy according to the new sepsis definition and assess their accuracy in comparison with existing models. Retrospective analysis of the nationwide survey for recombinant human soluble thrombomodulin. General emergency and critical care centres in secondary and tertiary care hospitals. We evaluated the prognostic value of the newly proposed diagnostic criteria for sepsis-induced coagulopathy (SIC). A total of 1498 Japanese patients with sepsis and coagulopathy complications who were treated with recombinant thrombomodulin were analysed in this study. The platelet count, prothrombin time (PT) ratio, fibrinogen/fibrin degradation products, systemic inflammatory response syndrome score and Sequential Organ Failure Assessment (SOFA) score obtained just before the start of treatment were examined in relation to the 28-day mortality rate. The platelet count, PT ratio and total SOFA were independent predictors of a fatal outcome in a logistic regression model. A SIC score was defined using the three above-mentioned variables with a positivity threshold of 4 points or more. The SIC score predicted higher 28-day mortality rate compared with the current Japanese Association for Acute Medicine-disseminated intravascular coagulation score (38.4%vs34.7%). The SIC score is based on readily available parameters, is easy to calculate and has a high predictive value for 28-day mortality. Future studies are warranted to evaluate whether the SIC score may guide the decision to initiate anticoagulant therapy. © Article author(s) (or their employer(s) unless

This study used a nationwide population-based reimbursement database to investigate the relationship between low-dose aspirin use and breast cancer incidence in women with diabetes. This retrospective cohort study was conducted using data retrieved from the National Health Insurance Research Database in Taiwan from January 1, 1998 to December 31, 2011. Women diagnosed as having diabetes with low-dose aspirin use (75-165 mg daily) were identified as the study population, whereas those without low-dose aspirin use were selected as the comparison group. We analyzed 148,739 patients with diabetes. Their mean age (standard deviation) was 63.3 (12.8) years. A total of 27,378 patients were taking aspirin. Overall, the use of aspirin in patients with diabetes reduced the risk of breast cancer by 18% (hazard ratio [HR], 0.82; 95% confidence interval [CI], 0.71-0.94) after adjustment for potential confounders, namely age and comorbidities. Specifically, a cumulative dose of aspirin exceeding 88,900 mg was observed to reduce the risk of breast cancer by 47% (HR, 0.53, 95% CI, 0.43-0.67); however, low (aspirin did not reduce the risk of breast cancer. Our findings suggest that a cumulative aspirin dosage of more than 88,900 mg daily was associated with a reduced risk of breast cancer in women with diabetes. However, additional studies are necessary to confirm these findings.

    The objective of the study was to assess common practice in pediatric epilepsy surgery in Italy between 2008 and 2014. A survey was conducted among nine Italian epilepsy surgery centers to collect information on presurgical and postsurgical evaluation protocols, volumes and types of surgical interventions, and etiologies and seizure outcomes in pediatric epilepsy surgery between 2008 and 2014. Retrospective data on 527 surgical procedures were collected. The most frequent surgical approaches were temporal lobe resections and disconnections (133, 25.2%) and extratemporal lesionectomies (128, 24.3%); the most frequent etiologies were FCD II (107, 20.3%) and glioneuronal tumors (105, 19.9%). Volumes of surgeries increased over time independently from the age at surgery and the epilepsy surgery center. Engel class I was achieved in 73.6% of patients (range: 54.8 to 91.7%), with no significant changes between 2008 and 2014. Univariate analyses showed a decrease in the proportion of temporal resections and tumors and an increase in the proportion of FCDII, while multivariate analyses revealed an increase in the proportion of extratemporal surgeries over time. A higher proportion of temporal surgeries and tumors and a lower proportion of extratemporal and multilobar surgeries and of FCD were observed in low (epilepsy surgery in Italy between 2008 and 2014, associated with a stable seizure outcome.

    Objective There have been no clinical studies regarding the epidemiology and treatment outcome for unruptured intracranial aneurysm (UIA) in South Korea yet. Thus, The Korean Society of Cerebrovascular Surgery (KSCVS) decided to evaluate the clinical and epidemiological characteristics, and outcome of the treatment of UIA in 2006, using the nationwide multicenter survey in South Korea. Methods A total of 1,696 cases were enrolled retrospectively over one year at 48 hospitals. The following data were obtained from all patients : age, sex, presence of symptoms, location and size of the aneurysm, treatment modality, presence of risk factors for stroke, and the postoperative 30-day morbidity and mortality. Results The demographic data showed female predominance and peak age of seventh and sixth decades. Supraclinoid internal carotid artery was the most common site of aneurysms with a mean size of 5.6 mm. Eight-hundred-forty-six patients (49.9%) were treated with clipping, 824 (48.6%) with coiling, and 26 with combined method. The choice of the treatment modalities was related to hospital (p = 0.000), age (p = 0.000), presence of symptom (p = 0.003), and location of aneurysm (p = 0.000). The overall 30-day morbidity and mortality were 7.4% and 0.3%, respectively. The 30-day mortality was 0.4% for clipping and 0.2% for coiling, and morbidity was 8.4% for clipping and 6.3% for coiling. Age (p = 0.010), presence of symptoms (p = 0.034), size (p = 0.000) of aneurysm, and diabetes mellitus (p = 0.000) were significant prognostic factors, while treatment modality was not. Conclusion This first nation-wide multicenter survey on UIAs demonstrates the epidemiological and clinical characteristics, outcome and the prognostic factors of the treatment of UIAs in South Korea. The 30-day postoperative outcome for UIAs seems to be reasonable morbidity and mortality in South Korea. PMID:20224709

    The integrated model of plastic surgery education, shortly to become the standard for all 6-year programs, has set minimal but no maximal exposure to plastic surgery. The authors hypothesized that the first 3 years of integrated training will show variability among residency programs. Rotation schedules for all 42 integrated programs were analyzed for plastic surgery versus 18 nonplastic surgery rotations for postgraduate years 1, 2, and 3 as well as cumulatively for the first 3 years. Rotations "strongly suggested" by the Residency Review Committee on Plastic Surgery and American Board of Plastic Surgery were also examined. Postgraduate years 1 through 3 spent a wide range of 3 to 19 months (SD ± 4.9 months) on plastic surgery (mean, 9.1 months). General surgery also varied dramatically, with 8 to 21 months (SD ± 4.0 months) of exposure (mean, 16.3 months). Surgical subspecialty rotations ranged substantially from 1 to 6 months (SD ± 1.0 months). Plastic surgery exposure was greater in programs based within plastic surgery departments than within divisions (13.8 versus 8.3 months, p plastic surgery experience in the first 3 years of residency training varies by a greater than 6-fold difference among integrated programs. This was also found in the 2.5-fold and 6-fold differences in general surgery and subspecialty surgery experiences. Since standardized residency training is an expectation by both accrediting bodies and the public, this variability may warrant closer attention.

    This study was designed to assess the relationship between insurance status and likelihood of receiving a neurosurgical procedure following admission for either extraaxial intracranial hemorrhage or spinal vertebral fracture. A retrospective analysis of the Nationwide Inpatient Sample (NIS; 1998-2009) was performed. Cases of traumatic extraaxial intracranial hematoma and spinal vertebral fracture were identified using International Classification of Diseases, Ninth Revision (ICD-9) diagnosis codes. Within this cohort, those patients receiving a craniotomy or spinal fusion and/or decompression in the context of an admission for traumatic brain or spine injury, respectively, were identified using the appropriate ICD-9 procedure codes. A total of 190,412 patients with extraaxial intracranial hematoma were identified between 1998 and 2009. Within this cohort, 37,434 patients (19.7%) received a craniotomy. A total of 477,110 patients with spinal vertebral fracture were identified. Of these, 37,302 (7.8%) received a spinal decompression and/or fusion. On multivariate analysis controlling for patient demographics, severity of injuries, comorbidities, hospital volume, and hospital characteristics, uninsured patients had a reduced likelihood of receiving a craniotomy (odds ratio [OR] 0.76, 95% confidence interval [CI] 0.71-0.82) and spinal fusion (OR 0.67, 95% CI 0.64-0.71) relative to insured patients. This statistically significant trend persisted when uninsured and insured patients were matched on the basis of mortality propensity score. Uninsured patients demonstrated an elevated risk-adjusted mortality rate relative to insured patients in cases of extraaxial intracranial hematoma. Among patients with spinal injury, mortality rates were similar between patients with and without insurance. In this study, uninsured patients were consistently less likely to receive a craniotomy or spinal fusion for traumatic intracranial extraaxial hemorrhage and spinal vertebral fracture

    Full Text Available The association between primary headaches, including tension-type headache (TTH as one of the most common primary headache disorders, and dementia remains controversial. In this nationwide, population-based, retrospective, cohort study, we explored the potential association between TTH and dementia and examined sex, age, and comorbidities as risk factors for dementia.Using the Taiwan National Health Insurance Research Database (NHIRD claims data, the sample included 13908 subjects aged ≥20 years with newly-diagnosed TTH in 2000-2006. The non-TTH group included 55632 randomly selected sex- and age-matched TTH-free individuals. All subjects were followed until dementia diagnosis, death, or the end of 2011. Patients with dementia, including vascular and non-vascular (including Alzheimer's subtypes, were identified using International Classification of Diseases Ninth Revision, Clinical Modification codes. Multivariate Cox proportional hazards regression models were used to assess the risk of dementia and dementia-associated risk factors, such as migraine and other medical comorbidities.During the average follow-up of 8.14 years, the incidence density rates of dementia were 5.30 and 3.68/1,000 person-years in the TTH and non-TTH groups, respectively. Compared with the non-TTH group, the risks of dementia were 1.25 (95% confidence interval [CI], 1.11-1.42 and 1.13 (95% CI, 1.01-1.27 times higher in the women and >65-year-old TTH group, respectively. TTH patients with comorbidities had a higher risk of dementia. TTH patients had a greater risk of non-vascular dementia (hazard ratio, 1.21; 95% CI, 1.09-1.34 than the non-TTH group.TTH patients have a future risk of dementia, indicating a potentially linked disease pathophysiology that warrants further study. The association between TTH and dementia is greater in women, older adults, and with comorbidities. Clinicians should be aware of potential dementia comorbidity in TTH patients.

    Full Text Available The objective of this study was to examine the association between obesity and all-cause mortality, length of stay and hospital cost among patients with sepsis 20 years of age or older.It was a retrospective cohort study. The dataset was the Nationwide Inpatient Sample 2011, the largest publicly available all-payer inpatient care database in the United States. Hospitalizations of sepsis patients 20 years of age or older were included. All 25 primary and secondary diagnosis fields were screened to identify patients with sepsis using International Classification of Diseases, Ninth Revision, Clinical Modification codes. Obesity was the exposure of interest. It was one of the 29 standardized Elixhauser comorbidity measures and readily available in the dataset as a dichotomized variable. The outcome measures were all-cause in-hospital death, length of stay and hospital cost.After weighting, our sample projected to a population size of 1,763,000, providing an approximation for the number of hospital discharges of all sepsis patients 20 years of age or older in the US in 2011. The overall all-cause mortality rate was 14.8%, the median hospital length of stay was 7 days and the median hospital cost was $15,917. After adjustment, the all-cause mortality was lower (adjusted OR = 0.84; 95% CI = 0.81 to 0.88; the average hospital length of stay was longer (adjusted difference = 0.65 day; 95% CI = 0.44 to 0.86 and the hospital cost per stay was higher (adjusted difference = $2,927; 95% CI = $1,606 to $4,247 for obese sepsis patients as compared to non-obese ones.With this large and nationally representative sample of over 1,000 hospitals in the US, we found that obesity was significantly associated with a 16% decrease in the odds of dying among hospitalized sepsis patients; however it was also associated with greater duration and cost of hospitalization.

    One by one, minimally invasive alternatives to established gastrointestinal procedures have become clinical routine. We have studied the use of laparoscopy in four common procedures-cholecystectomy, appendectomy, reflux surgery, and bariatric surgery-as well as in major resectional gastrointestinal surgery in Sweden. The National Patient Registry was used to identify all in-hospital procedures performed in patients above the age of 15 during 1998-2014, meeting our inclusion criteria. For each group, the annual number of procedures and proportion of laparoscopic surgery were studied, as well as applicable subgroups. Differences in age, gender, as well as geographical differences were evaluated in the most recent 3-year period (2012-2014). In total, 537,817 procedures were studied, 43% by laparoscopic approach. In 2012-2014, the proportion of laparoscopic surgery ranged from high rates in the four common procedures (cholecystectomy 81%, appendectomy 47%, reflux surgery 72%, and bariatric surgery 97%) to rather low numbers in resectional surgery (4%-10%), however, increasing in the last years. In appendectomy and cholecystectomy, men were less likely to have laparoscopic surgery (42% versus 51% and 74% versus 85%, respectively, p laparoscopy were also noted, for example, the proportion of laparoscopic appendectomy varied from 11% to 76% among the 21 different Swedish counties. The proportion of laparoscopy was high in the four common procedures and low, but rising, in major resectional surgery. A large variation in the proportion of laparoscopic surgery by age, gender, and place of residence was noted.

    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.

The perioperative outcomes and oncologic outcomes were compared between laparoscopic and open surgery.Results: Of 226 patients with transverse colon cancer, 103 underwent laparoscopic surgery and 123 underwent open surgery. There were no differences in the patient characteristics between the two groups. Regarding perioperative outcomes, the operation time was significantly longer in the laparoscopic group than in the open group (267.3 vs 172.7 minutes, P<0.001, but the time to soft food intake (6.0 vs 6.6 days, P=0.036 and the postoperative hospital stay (13.7 vs 15.7 days, P=0.018 were shorter in the laparoscopic group. The number of harvested lymph nodes was lower in the laparoscopic group than in the open group (20.3 vs 24.3, P<0.001. The 5-year overall survival (90.8% vs 88.6%, P=0.540 and disease-free survival (86.1% vs 78.9%, P=0.201 rates were similar in both groups.Conclusion: The present study showed that laparoscopic surgery is associated

    The incidence of symptomatic adjacent segment disease (ASD) after anterior cervical diskectomy and fusion (ACDF) was reported as 2.9%/y in a previous cohort of 374 patients. Few other data corroborate the incidence and natural history of ASD. To calculate the incidence of ASD after ACDF that required secondary fusion surgery. The retrospective study used an 11-year nationwide database to analyze the incidences. All patients who underwent ACDF for cervical disk diseases were identified through diagnostic and procedure codes. Kaplan-Meier and Cox regression analyses were performed. From 1997 to 2007, covering 241 800 725.8 person-years, 19 385 patients received ACDF and 568 had ≥ 2 ACDF operations. The incidence of secondary ACDF operations was 7.6 per 1000 person-years. At the end of the 10-year cohort, 94.4% of patients who had received 1 ACDF remained free from secondary ACDF. The average time interval between the first and second ACDF was 23.3 months. After adjustment for comorbidities and socioeconomic status, secondary ACDF operations were more likely performed on male patients (hazard ratio = 1.27; P = .008) 15 to 39 years of age (hazard ratio = 1.45; P = .009) and 40 to 59 years of age (hazard ratio = 1.41, P = .002, respectively). Repeat ACDF surgery for ASD cumulated steadily in an annual incidence of approximately 0.8%, much lower than the reported incidence of symptomatic ASD. However, at the end of this 10-year cohort, a considerable portion of patients (5.6%) received a second operation. Younger and male patients are more likely to receive such second operations.

  9. A Retrospective Study of Surgery and Reirradiation for Recurrent Ependymoma

    Merchant, Thomas E.; Boop, Frederick A.; Kun, Larry E.; Sanford, Robert A.

    2008-01-01

    Purpose: To report disease control for patients with recurrent ependymoma (EP) treated with surgery and a second course of radiation therapy (RT 2 ). Patients and Methods: Thirty-eight pediatric patients (median age, 2.7 years) with initially localized EP at the time of definitive RT underwent a second course of RT after local (n = 21), metastatic (n = 13), or combined (n = 4) failure. Reirradiation included radiosurgery (n = 6), focal fractionated reirradiation (n = 13), or craniospinal irradiation (CSI; n = 19). Results: Initial time to failure was 16 months, and median age at second treatment was 4.8 years. Radiosurgery resulted in significant brainstem toxicity and one death (median dose, 18 Gy). Progression-free survival ratio was greater than unity for 4 of 6 patients; there was one long-term survivor. Three of 13 patients treated using focal fractionated reirradiation (median combined dose, 111.6 Gy) experienced metastasis. The CSI was administered to 12 patients with metastatic failure, 3 patients with local failure, and 4 patients with combined failure. The 4-year event-free survival rate was 53% ± 20% for 12 patients with metastatic failure treated with CSI. Failure after CSI was observed in 1 of 3 patients with a history of local failure and 3 of 4 patients with a history of combined failure. Conclusion: Patients with locally recurrent EP experience durable local tumor control, but remain at risk of metastasis. Patients with metastatic EP failure may receive salvage therapy that includes a component of CSI. Durability of disease control and long-term effects from this approach require further follow-up

    Practitioners who are not board-certified by the American Board of Plastic Surgery are practicing cosmetic surgery. The extent of this issue across the United States has yet to be examined in detail. A systematic search using Google was performed to evaluate the qualifications of clinicians marketing themselves as plastic surgeons. For every U.S. state, the following searches were performed: [state] plastic surgery, [state] cosmetic surgery, and [state] aesthetic surgery. The first 50 Web sites returned for each search were visited and scrutinized using the American Society of Plastic Surgeons and American Board of Plastic Surgery Web sites. In total, 7500 Web sites were visited, yielding 2396 board-certified plastic surgeons (77.9 percent of all practitioners). There were 284 board-certified ear, nose, and throat surgeons, 61 (21.5 percent) of whom practice outside their scope; 106 board-certified general surgeons, 100 (94.3 percent) of whom practice outside their scope; 104 board-certified oral and maxillofacial surgery surgeons, 68 (65.4 percent) of whom practice outside their scope; 70 board-certified ophthalmologists/oculoplastic surgeons, 49 (70 percent) of whom practice outside their scope; and 74 board-certified dermatologists, 36 (48.6 percent) of whom practice outside their scope. There were also 16 internal medicine doctors, 13 obstetrics and gynecology physicians, six emergency medicine physicians, three pediatricians, two urologists, two anesthesiologists, and finally one phlebotomist; all of these practitioners practice outside their scope as defined by Accreditation Council for Graduate Medical Education core competencies. Many clinicians performing cosmetic surgery are not board-certified. This finding has important implications for patient safety.

    Although, the vast majority of bariatric procedures worldwide are performed laparoscopically, there is no consensus on the best technique to enter the first trocar, a potentially dangerous maneuver. Three principally different techniques exist: initial pneumoperitoneum by Verres needle, open Hasson technique, and direct placement of an optical trocar. In this nationwide survey, we have studied the presently used technique to place the first trocar and identified any intraabdominal injuries in 2012-2014. A questionnaire concerning techniques for placing the first trocar and identified intraabdominal injuries was sent to all 41 centers performing laparoscopic Roux en-Y gastric bypass (LRYGB) in Sweden. Total number of procedures were collected from the national quality registry, Scandinavian Obesity Surgery Registry (SOReg), also searched for reports on intraabdominal injuries. During the present study period, 17,446 LRYGBs were performed. Twelve intraabdominal injuries (0.07 %) were found: bleedings from the omentum, small bowel mesentery and liver (n = 8), and gastric or small bowel perforation (n = 4). The injuries were evenly distributed between the Veress technique and direct placement of an optical trocar, while no injuries occurred with the Hasson technique. Concerning placement of the first trocar, initial pneumoperitoneum with Veress needle was most common (59 %), followed by direct placement of an optical trocar (30 %). This indicates a switch from 2009-2010 (Veress 45 % and optical trocar 45 %, p < 0.001). Twelve intraabdominal injuries (0.07 %) were found in this nationwide survey. The most common technique for placing the first trocar had switched from directly placing an optical trocar to prior establishment of pneumoperitoneum.

This study utilized a subset of the National Health Insurance Research Database, which includes the data on all paid medical benefit claims from 1997 to 2007, for 1 million beneficiaries in 2005. We analyzed the claims data for all patients with hypospadias who had undergone primary urethroplasty. The characteristics of the patients, surgeons, and hospitals associated with surgical outcomes were analyzed to investigate possible associations with the need for secondary surgery. Among 52,705 live male newborn babies, 218 were diagnosed with hypospadias, of whom 89 received repair surgery. A total of 75 (84.3%) male newborn babies received single hypospadias surgery, and 14 (15.7%) underwent more than two surgical procedures. Univariate analysis demonstrated that the type of hypospadias and the surgeon caseload volume were significantly associated with the need for additional hypospadias surgery (p = 0.02 and p = 0.03, respectively). In multivariate analysis, the type of hypospadias (distal vs. proximal, odds ratio, 0.25; p = 0.03) and the surgeon caseload volume (high vs. low, odds ratio, 0.04; p = 0.05) were significantly correlated with secondary operation. The type of hypospadias and the surgeon caseload volume were significantly associated with the need for secondary hypospadias surgery. The findings of this study provide important information on the outcomes of hypospadias repair for parents and specialists. Copyright © 2017. Published by Elsevier Taiwan.

    Maxillomandibular advancement has been shown to be one of the most effective operations for management of severe obstructive sleep apnea, yet pharyngeal surgery is more commonly performed. The goal of this study was to identify socioeconomic factors associated with this phenomenon. Patients aged 14 or older with a primary hospital diagnosis of sleep apnea were identified using the National Inpatient Sample from 2005 to 2012. ICD9 codes were used to determine whether a pharyngeal or jaw procedure was performed. Patient demographics, comorbidities, and complications were compared. Among 6316 sleep surgeries, 5964 (94.4%) were pharyngeal and 352 (5.6%) were jaw procedures. Women were significantly more likely to receive jaw surgery than men (odds ratio [OR] = 1.68, P = 0.0007). African Americans (OR = 0.19, P < 0.0001), Hispanics (OR = 0.42, P = 0.0009), Asians (OR = 0.41, P = 0.0009), and other non-Caucasians (OR = 0.19, P = 0.0008) had a significantly lower odds of receiving jaw surgery than Caucasians. Patients falling into lower-income brackets (OR = 0.39 and 0.57, P = 0.02 and 0.04) and patients with Medicare compared with private or Health Maintenance Organization insurance (OR = 0.46, P = 0.008) also had significantly decreased odds of undergoing jaw surgery. Comorbidities were similar between surgical groups, and there were no significant differences in bleeding, infection, or cardiopulmonary complications. We identified no significant difference in complication rates between pharyngeal and jaw procedures. Nonetheless, African American, Hispanic, and Asian patients, in addition to lower-income patients and patients with Medicare, had a significantly lower odds of receiving jaw surgery. Awareness of these disparities may help guide efforts to improve patients' surgical options for sleep apnea.

    Robot-assisted anti-reflux surgery (RAAS) is an alternative to conventional laparoscopic anti-reflux surgery (CLAS). The purpose of this study was to evaluate initial Danish experiences with robot-assisted anti-reflux surgery compared to conventional laparoscopic anti-reflux surgery incorporating follow-up and evaluation of possible learning curve. Patients undergoing primary RAAS or CLAS at The Department of Surgery A, Odense University Hospital and The Department of General Surgery, Kolding Hospital from April 2013 to April 2015 was included. Demographic data, comorbidity, docking time, length of procedure, type of fundic wrap as well as perioperative complications and postoperative complications, need for reoperation or any upper gastrointestinal endoscopy from surgery to final follow-up was retrospectively extracted from patient records. 103 patients were included in this study. 39 patients underwent RAAS and 64 patients underwent CLAS. There were no statistically significant differences in demographic data or comorbidities except distribution of heart disease (RAAS: 5.1% vs. CLAS: 18.8%, p = 0.05) and previous abdominal surgery (RAAS: 28.2% vs. CLAS: 48.4%, p = 0.04). Duration of surgery was significantly increased in patients undergoing RAAS (RAAS: 135 ± 27 min vs. CLAS: 86 ± 19 min, p surgery as robot-assisted procedures neither intra-operatively nor at follow-up.

    A multicenter, retrospective review of C5 palsy after cervical spine surgery. Postoperative C5 palsy is a known complication of cervical decompressive spinal surgery. The goal of this study was to review the incidence, patient characteristics, and outcome of C5 palsy in patients undergoing cervical spine surgery. We conducted a multicenter, retrospective review of 13 946 patients across 21 centers who received cervical spine surgery (levels C2 to C7) between January 1, 2005, and December 31, 2011, inclusive. P values were calculated using 2-sample t test for continuous variables and χ 2 tests or Fisher exact tests for categorical variables. Of the 13 946 cases reviewed, 59 patients experienced a postoperative C5 palsy. The incidence rate across the 21 sites ranged from 0% to 2.5%. At most recent follow-up, 32 patients reported complete resolution of symptoms (54.2%), 15 had symptoms resolve with residual effects (25.4%), 10 patients did not recover (17.0%), and 2 were lost to follow-up (3.4%). C5 palsy occurred in all surgical approaches and across a variety of diagnoses. The majority of patients had full recovery or recovery with residual effects. This study represents the largest series of North American patients reviewed to date.

    To validate the comprehensive features of adverse outcomes after surgery for patients with myasthenia gravis. Using reimbursement claims from Taiwan's National Health Insurance Research Database, we analyzed 2290 patients who received major surgery between 2004 and 2010 and were diagnosed with myasthenia gravis preoperatively. Surgical patients without myasthenia gravis (n = 22,900) were randomly selected by matching procedure with propensity score for comparison. The adjusted odds ratios and 95% confidence intervals of postoperative adverse events associated with preoperative myasthenia gravis were calculated under the multiple logistic regressions. Compared with surgical patients without myasthenia gravis, surgical patients with myasthenia gravis had higher risks of postoperative pneumonia (OR = 2.09; 95% CI: 1.65-2.65), septicemia (OR = 1.31; 95% CI: 1.05-1.64), postoperative bleeding (OR = 1.71; 95% CI: 1.07-2.72), and overall complications (OR = 1.70; 95% CI: 1.44-2.00). The ORs of postoperative adverse events for patients with myasthenia gravis who had symptomatic therapy, chronic immunotherapy, and short-term immunotherapy were 1.76 (95% CI 1.50-2.08), 1.70 (95% CI 1.36-2.11), and 4.36 (95% CI 2.11-9.04), respectively. Patients with myasthenia gravis had increased risks of postoperative adverse events, particularly those experiencing emergency care, hospitalization, and thymectomy for care of myasthenia gravis. Our findings suggest the urgency of revising protocols for perioperative care for these populations.

    Enhanced Recovery After Surgery (ERAS) programmes aim at an early recovery after surgical trauma and consequently at a reduced length of hospitalisation. This paper presents the protocol for a study that focuses on large-scale implementation of the ERAS programme in major gynaecological surgery in the Netherlands. The trial will evaluate effectiveness and costs of a stepped implementation approach that is characterised by tailoring the intensity of implementation activities to the needs of organisations and local barriers for change, in comparison with the generic breakthrough strategy that is usually applied in large-scale improvement projects in the Netherlands. All Dutch hospitals authorised to perform major abdominal surgery in gynaecological oncology patients are eligible for inclusion in this cluster randomised controlled trial. The hospitals that already fully implemented the ERAS programme in their local perioperative management or those who predominantly admit gynaecological surgery patients to an external hospital replacement care facility will be excluded. Cluster randomisation will be applied at the hospital level and will be stratified based on tertiary status. Hospitals will be randomly assigned to the stepped implementation strategy or the breakthrough strategy. The control group will receive the traditional breakthrough strategy with three educational sessions and the use of plan-do-study-act cycles for planning and executing local improvement activities. The intervention group will receive an innovative stepped strategy comprising four levels of intensity of support. Implementation starts with generic low-cost activities and may build up to the highest level of tailored and labour-intensive activities. The decision for a stepwise increase in intensive support will be based on the success of implementation so far. Both implementation strategies will be completed within 1 year and evaluated on effect, process, and cost-effectiveness. The primary

    To predict the probability of lymphedema development in breast cancer patients in the early post-operation stage, we investigated the ability of quantitative lymphoscintigraphic assessment. This retrospective study included 201 patients without lymphedema after unilateral breast cancer surgery. Lymphoscintigraphy was performed between 4 and 8 weeks after surgery to evaluate the lymphatic system in the early postoperative stage. Quantitative lymphoscintigraphy was performed using four methods: ratio of radiopharmaceutical clearance rate of the affected to normal hand; ratio of radioactivity of the affected to normal hand; ratio of radiopharmaceutical uptake rate of the affected to normal axilla (RUA); and ratio of radioactivity of the affected to normal axilla (RRA). During a 1-year follow-up, patients with a circumferential interlimb difference of 2 cm at any measurement location and a 200-mL interlimb volume difference were diagnosed with lymphedema. We investigated the difference in quantitative lymphoscintigraphic assessment between the non-lymphedema and lymphedema groups. Quantitative lymphoscintigraphic assessment revealed that the RUA and RRA were significantly lower in the lymphedema group than in the non-lymphedema group. After adjusting the model for all significant variables (body mass index, N-stage, T-stage, type of surgery, and type of lymph node surgery), RRA was associated with lymphedema (odds ratio=0.14; 95% confidence interval, 0.04-0.46; p=0.001). In patients in the early postoperative stage after unilateral breast cancer surgery, quantitative lymphoscintigraphic assessment can be used to predict the probability of developing lymphedema.

    Throat packs are commonly used to prevent ingestion or aspiration of blood and other debris during cleft lip/palate surgery. However, dislodgement or (partial) retainment after extubation could have serious consequences. The aim of the present study was to investigate the effect of omitting pharyngeal packing during cleft lip/palate surgery on the incidence of early postoperative complications in children. A retrospective study was performed on all children who underwent cleft lip/palate surgery at the Wilhelmina Children's Hospital. This study compared the period January 2010 through December 2012 when pharyngeal packing was applied according to local protocol (group A) with the period January 2013 till December 2015 when pharyngeal packing was no longer applied after removal from the protocol (group B). Data were collected for sex, age at operation, cleft lip/palate type, type of repair, lateral incisions, length of hospital stay, and complications in the first 6 weeks after surgery. Early complications included wound dehiscence, postoperative bleeding, infection, fever, upper respiratory tract infection (URTI), and lower respiratory tract infection (LRTI). This study included 489 cleft lip/palate operations (group A n = 246, group B n = 243). A total of 39 (15.9%) early complications were recorded in group A and a total of 40 (16.5%) in group B. There were no significant differences (P = 0.902) in complications between the two groups; however, there was a significant difference (P cleft lip/palate surgery was not associated with an increased early postoperative complication rate. Therefore, the traditional, routine placement of a throat pack during cleft lip/palate surgery can be questioned.

    Full Text Available Background Laparoscopic renal surgery has been widely used in the treatment of renal diseases. However, there is still little research about its application in addressing renal tuberculosis. The purpose of this study is to retrospectively investigate the surgical results of laparoscopic and open surgery for nonfunctional tuberculous kidneys. Methods Between May 2011 and June 2016, 120 nephrectomies were performed in patients with a nonfunctional tuberculous kidney. Of these, 69 patients underwent retroperitoneal laparoscopic nephrectomy, and 51 patients underwent open nephrectomy. Data about the patients’ characteristics and surgical outcomes were collected from their electronic medical records. Outcomes were compared between these two groups. Results Our results showed that a number of renal tuberculosis patients presented no significant symptoms during their disease. Lower urinary tract symptoms (LUTS were the most common at a rate of 73/120, followed by flank pain or accidently discovery (66/120, urine abnormality (30/120 and fever (27/120. Patients who underwent open surgery were similar to laparoscopic patients with regard to sex, BMI, location, previous tuberculous history, grade, anemia, adhesion, hypertension, diabetes and preoperative serum creatinine level, but were generally older than laparoscopic patients. There were no significant differences between open and laparoscopic surgery in estimated blood loss, transfusion, postoperative hospital days and perioperative complication rate. However, the median operation time of laparoscopic operation was much longer than open surgery (180 [150–225] vs 135 [120–165] minutes, P < 0.01. Seven of the 69 laparoscopic operations were converted to open surgery because of severe adhesions. Conclusion Laparoscopic nephrectomy is as an effective treatment as open surgery for a nonfunctional tuberculous kidney, although it requires more time during the surgical procedure. No significant

    Nonrechargeable deep brain stimulation impulse generators (IGs) with low or empty battery status require surgical IG exchange several years after initial implantation. The aim of this study was to investigate complication rates after IG exchange surgery and identify risk factors. We retrospectively analyzed complications following IG exchange surgery from 2008 to 2015 in our department. Medical records of all patients who underwent IG exchange surgery were systematically reviewed. The shortest follow-up time was 19 months. From 2008 to 2015, 438 IGs were exchanged in 319 patients. Overall complication rate was 8.90%. Infection developed in 12 patients (2.74%). Six patients (1.37%) experienced local wound erosions. Hardware malfunctions were present in 11 patients (2.51%), and local hemorrhage was observed in 3 cases (0.68%). Repeated fixation of the IG was required in 2 patients (0.46%). Traction of the connecting cables necessitated surgical revision in 2 patients (0.46%). In 2 cases (0.46%), the IG was placed abdominally or exchanged for a smaller device owing to patient discomfort resulting from the initial positioning. One 80-year-old patient (0.23%) had severely worsening heart failure and died 4 days after IG exchange surgery. IG exchange surgery, although often considered a minor surgery, was associated with a complication rate of approximately 9% in our center. Patients and physicians should understand the complication rates associated with IG exchange surgery because this information might facilitate selection of a rechargeable IG.

    Despite the broad category of differentials for sellar region, most of them present with similar clinical signs and symptoms. Headache and visual disturbance are among the frequently seen as presenting symptom. Visual field (VF) assessment is one of the crucial component of neuroophtalmologic assessment and mean deviation (MD) value from automated perimetry allows quantification of the visual field defect. We formulated a study to look into the factors that affect the visual field outcome after surgery. All patients with sellar region tumor who has underwent surgery in Queen Elizabeth Hospital from July 2010 to July 2016 were retrospectively analysed through hospital notes. VF assessment via Humphrey visual assessment for these patient pre and post-surgery were reviewed for MD value. Eighty four patients were recruited and out of them, 151 eyes were taken into analysis after excluding eyes with missing data. Mean age of patients were 45.4 years with 70.2% of them were male. Visual disturbance is the commonest presenting symptom with mean duration of symptom prior to surgery is 9.7 months. Majority of them were pituitary adenomas (75%) followed by sellar meningioma (19%), craniopharyngioma (4.8%), and rathke cleft cyst (1.2%). 70.9% of patients showed improvement in VF based on MD outcome. Mean MD for pre surgery and post-surgery were -14.0 dB and -12.4 dB, respectively. Univariate analysis reveals younger age, female sex, shorter duration of symptom, pituitary adenoma, transsphenoidal approach, and transcranial approach favours improvement in VF. Multivariate analysis shows only shorter symptom duration, transphenoidal approach, and transcranial approach are significant for favourable VF outcome when other factors adjusted. Symptom duration and surgical approach were independent factors that affects the visual field after surgery in patients with sellar region tumors.

    A retrospective review. To review the effectiveness of blood conservation techniques in the spinal fusion of patients that refuse blood transfusion; specifically the Jehovah's witnesses population. Spinal surgery can be challenging in patients refusing blood transfusion. There is paucity in the literature examining blood conservation techniques in spinal surgery. The radiographic and medical records of 19 Jehovah's witnesses patients who underwent spinal deformity surgery at a single institution between 2000 and 2003 were reviewed. Patients were assessed for excessive blood loss (EBL), deformity correction, operative time, perioperative complications, and hospital stay. At latest follow-up (mean, 40 months; range, 8-76) the patients were examined for radiographic fusion, progression and complications. Spinal fusion was attempted in 19 patients, with a mean age of 17 years (range, 10-36 years). All 19 patients were identified through the "Bloodless Surgery Program." Hypotensive anesthesia, hemodilution, and cell saver was employed for all 19 cases. Erythropoietin with supplemental iron was used in 15 patients. Aprotinin was used in 3 patients. EBL and blood returned by cell saver averaged 855 and 341 mL, respectively. Operative times average 315 minutes. The average drop in hemoglobin from after surgery was 3.1 g/dL. There were 2 intraoperative complications: (i) transient loss of somatosensory evoked potential/motor evoked potential signals; and (ii) one surgery abandoned due to EBL. The average spinal deformity correction was 58%. There were 3 postoperative complications, none related to their refusal of a transfusion. 17 patients were available for radiographic and clinic follow-up of at least 24 months. All displayed radiographic fusion without progression. These blood conservation techniques allow satisfactory completion of deformity surgery on those patients not willing to be transfused and without major anesthetic or medical complications.

    Various definitions for bariatric surgery (BS) success exist, with weight loss and comorbidity resolution outcomes being the most prominent. The study's aim was to compare how various healthcare professionals perceive success in BS. A 29-item, 10-point Likert scale online survey was distributed via email to Israeli healthcare professionals involved in the different BS aspects using common national professional organizations. These included bariatric surgeons, dietitians, social workers, psychologists, psychiatrists, primary care physicians, gastroenterologists, and nurses. Statement relevancy to BS success was rated. An item was classed as "very important" for BS success if at least 70% of participants rated it 8 or higher in each subgroup. Inter-observer agreement was calculated using kappa statistics. Data on specific occupation, years-in-practice, and major workplace were collected as well. A total of 155 responses was obtained. The majority of respondents were dietitians (34.8%, n = 54), followed by bariatric surgeons (31.0%, n = 48) and nurses (14.8%, n = 23). Most respondents work mainly at public hospitals (32.9%, n = 51), followed by private hospitals (26.5%, n = 41). The mean years-in-practice among all healthcare professionals was 8.5 ± 8.5 years. Overall inter-observer agreement for prioritized items in accordance to BS success among all health professional subgroups was fair (Fleiss kappa = 0.278, P success by different healthcare professionals, although there was some overlap of core outcomes prioritized by all professionals. International uniform definitions for BS success are required.

    To determine the incidence of retinitis pigmentosa (RP) in South Korea. Nationwide, population-based retrospective study. Census population of South Korea PARTICIPANTS: This study involved the entire population of South Korea (n=47 990 761). Patients confirmed as having RP by an ophthalmologist from 1 January 2011 to 31 December 2014 were included. The average incidence of RP during the 4-year study period was estimated using population data from the 2010 Korean census. A total of 3144 (1567 men and 1577 women) patients confirmed as having RP were identified. The average incidence of RP was 1.64 cases/100 000 person-years (95% CI 1.58 to 1.70). The incidence of RP distribution skewed to the left across age groups, with one smaller peak observed in the 20-24-year-old age group (1.24 cases/100 000 person-years) and a larger peak observed in the 65-69-year-old age group (3.26 cases/100 000 person-years). The overall incidence was similar in men and women (1.64 cases/100 000 person-years (95% CI 1.56 to 1.73) for men; 1.63 cases/100 000 person-years (95% CI 1.55 to 1.72) for women). Our study's estimates of the nationwide population-based incidence of RP in an Asian population will help advance the understanding of the disease onset and allow healthcare systems to plan accordingly. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Febrile convulsions and allergic rhinitis are both common childhood disorders and both are considered as generally benign disorders. Yet, especially in the case of allergic rhinitis, adverse effects on school performance and limited socialization are found. The relationship between febrile convulsions and allergic rhinitis has not been previously reported; thus, this article seeks to explore the association between these two disorders by collecting data from the Taiwanese nationwide cohort database. A total of 1304 children with febrile convulsions were identified as the case cohort, and controls were matched based on age, sex, urbanization levels, and parents' occupation on a 1 to 4 ratio. Cox's proportional hazards regression model was used to estimate the hazard ratio and confidence interval of allergic rhinitis disorder among children with febrile convulsions. During an average 6.7 years follow-up period, the incidence of allergic rhinitis in the febrile convulsions case group was higher (65.16 vs 51.45 per 1000 person-years). After 11 years of follow-up, the allergic rhinitis incidence in the febrile convulsion patients was approximate 4% higher than controls (log-rank test P allergic rhinitis in the febrile convulsions group was found to be 1.21 times higher than in the control group (95% confidence interval, 1.08-1.36). This risk of allergic rhinitis development is further increased (0.94 vs 18.9) with frequency of febrile convulsions-related medical visits (one to three visits vs more than three visits, P allergic rhinitis occurrence in children. Children with more than three febrile convulsion-related medical visits had a significantly higher cumulative incidence of allergic rhinitis.

    Based on the mechanism of pathophysiology, thalassemia major or transfusion-dependent thalassemia patients may have an increased risk of developing organic erectile dysfunction resulting from hypogonadism. However, there have been few studies investigating the association between erectile dysfunction and transfusion-naive thalassemia populations. We constructed a population-based cohort study to elucidate the association between transfusion-naive thalassemia populations and organic erectile dysfunction. This nationwide population-based cohort study involved analyzing data from 1998 to 2010 obtained from the Taiwanese National Health Insurance Research Database, with a follow-up period extending to the end of 2011. We identified men with transfusion-naive thalassemia and selected a comparison cohort that was frequency-matched with these according to age, and year of diagnosis thalassemia at a ratio of 1 thalassemia man to 4 control men. We analyzed the risks for transfusion-naive thalassemia men and organic erectile dysfunction by using Cox proportional hazards regression models. In this study, 588 transfusion-naive thalassemia men and 2337 controls were included. Total 12 patients were identified within the thalassaemia group and 10 within the control group. The overall risks for developing organic erectile dysfunction were 4.56-fold in patients with transfusion-naive thalassemia men compared with the comparison cohort after we adjusted for age and comorbidities. Our long-term cohort study results showed that in transfusion-naive thalassemia men, there was a higher risk for the development of organic erectile dysfunction, particularly in those patients with comorbidities.

    Bariatric surgery for severe obesity has become an effective and accepted treatment for sustained weight loss. The aim of our study was to analyze the complications and issues raised by the experts on which jury or judges' decisions were made for the different types of bariatric surgery. University Hospital, France. We have carried out a retrospective study of 59 expert review dossiers over a period of 15 years (1999-2014) on the different types of bariatric surgery (laparoscopic adjustable gastric band [LAGB], sleeve gastrectomy [SG], Roux-en-Y gastric bypass [RYGB], vertical banded gastroplasty [VBG], and gastric plication [GP]). Of the cases, 81% were women and the average age was 39 years old (range 19 to 68 years). Among the procedures giving rise to the complaints, 40% were for LAGB, 28% for RYGB, and 23% for SG. The most common initial complications were perforations (30%), fistulae (27%), bowel obstruction (14%), vascular injuries (9.5%), and infections (peritonitis, pleurisy, abscesses, and so forth) (8%). Revision surgery was required in 78% of patients, and perioperative complications accounted for 28.5% of dossiers. The experts concluded that fault had occurred in 40% of case. Negligence arising from an error deemed to be an act of negligence was found in 30% of cases, 67% of which were because of delayed diagnosis. Major long-term complications accounted for 8% of dossiers and minor long-term complications for 22%. Forty-seven percent of patients completely recovered. Delayed diagnosis was the main error established by the experts. Surgeons should remain vigilant postoperatively after every bariatric surgical procedure.

    Surgical site infection (SSI) is a serious postoperative complication. The incidence of SSIs is lower in clean orthopedic surgery than in other fields, but it is higher after spinal surgery, reaching 4.15% in high-risk patients. Several studies reported that triclosan-coated polyglactin 910 sutures (Vicryl Plus; Ethicon, Inc., Somerville, NJ, USA) significantly reduced the infection rate in the general surgical, neurosurgical, and thoracic surgical fields. However, there have been no studies on the effects of such coated sutures on the incidence of SSIs in orthopedics. To compare the incidence of wound infections after spinal surgery using triclosan-coated suture materials with that of noncoated ones. A retrospective, nonrandomized, and clinical study. From May 2010 to April 2012, 405 patients underwent a spinal surgical procedure in the Department of Orthopedic Surgery of two university hospitals. The primary outcome was the number of wound infections and dehiscences. Two hundred five patients had a conventional wound closure with polyglactin 910 suture (Vicryl) between May 2010 and April 2011 (Time Period 1 [TP1]), and 200 patients underwent wound closure with triclosan-coated polyglactin 910 suture (Vicryl Plus) between May 2011 and April 2012 (TP2). Statistical comparisons of wound infections, dehiscence, and risk factors for poor wound healing or infection were performed. None of the authors has any conflict of interest associated with this study. There were two cases of wound dehiscence in TP1 and one in TP2 (p=.509). Using noncoated sutures in TP1, eight patients (3.90%) had wound infections, whereas one patient (0.50%) had wound infections in TP2 (using triclosan-coated sutures); the difference was significant (p=.020). The use of triclosan-coated polyglactin 910 sutures instead of polyglactin 910 sutures may reduce the number of wound infections after spinal surgery. Copyright © 2015 Elsevier Inc.

    We evaluated recurrence outcomes of penile sparing surgery in what is to our knowledge the largest multicenter cohort of patients to date. We retrospectively identified patients treated with penile sparing surgery from May 1990 to July 2016 at 5 tertiary referral institutions. Treatments consisted of circumcision, wide local excision, laser therapy with or without local excision, partial or total glansectomy and glans resurfacing. The study primary end point was local recurrence-free survival, defined from initial treatment to time of local recurrence and estimated with the Kaplan-Meier method. After applying study exclusion criteria 1,188 patients were included in analysis. During the median followup of 43.0 months there were 252 local recurrences (21.2%), of which 99 (39.3%) developed in year 1. Median time to local recurrence was 16.3 months and the 5-year local recurrence-free survival incidence was 73.6%. When stratified by stage, the 5-year local recurrence-free survival rate was 75.0%, 71.4% and 75.9% in Ta/Tis, T1 and T2 cases, respectively (log rank p = 0.748). Of the recurrences 58.3% were treated with repeat organ sparing procedures and the secondary partial (total) penectomy rate was 19.0%. Only margin status was significantly associated with local recurrence on multivariate analysis (p = 0.001). Study limitations included the retrospective design and the heterogeneous clinical approach. Penile sparing surgery can provide excellent local control for superficial penile tumors as well as for appropriately selected invasive lesions. Strict followup in the early postoperative period is highly recommended. Copyright © 2018 American Urological Association Education and Research, Inc. Published by Elsevier Inc. All rights reserved.

    Stroke after coronary by-pass grafting (CABG) is often disabling. The incidence of ischemic stroke may approach 3% to 5%. Several risk factors have been identified including previous history of stroke, prolonged cardiopulmonary bypass time, and postoperative atrial fibrillation. Objective was to determine the incidence and risk factors of neurological deficit after open heart surgery. Retrospective study was done during the period 1992-1995 at the King Khalid University Hospital, Riyadh, Saudi Arabia. There were 350 patients who were subjected to (CABG), 10 patients (2.8%) found to suffer from cerebrovascular accidents (CVA) following open-heart surgery. In 8 patients, the complaint lasted more than 24 hours (stroke), while 2 patients developed transient ischemic attacks (TIA). Five factors were found to be associated with increased risk of post cardiac surgery CVA. These factors are postoperative atrial fibrillation, carotid bruit, past history of heart failure, past history of CVA and smoking. The authors concluded that it is necessary to start a prospective study to verify the area of improvement with regards to technique, selection of patients and mode of perfusion during cardiopulmonary bypass (CPB) Arabia.

    There are limited data regarding blood transfusion following abdominoplasty, especially in post-bariatric surgery patients. The purpose of this study was to evaluate (1) the frequency and outcomes of blood transfusion in post-bariatric surgery patients undergoing abdominoplasty and (2) the predictive risk factors of blood transfusion in this patient population. Using the Nationwide Inpatient Sample database, the authors examined the clinical data of patients with a history of bariatric surgery who underwent abdominoplasty from 2007 to 2011 in the United States. A total of 20,130 post-bariatric surgery patients underwent abdominoplasty during this period. Overall, 1871 patients (9.3 percent) received blood transfusion. Chronic anemia patients had the highest rate of blood transfusion (25.6 percent). Post-bariatric surgery patients who received blood transfusion experienced a significantly higher complication rate (10.1 percent versus 4.8 percent; p blood transfusion. The blood transfusion rate in post-bariatric surgery abdominoplasty patients is not insignificant. Chronic anemia and congestive heart failure are the two major predictors of transfusion. Modifying risk factors such as anemia before abdominoplasty might significantly decrease the possibility of blood transfusion. Risk, III.

    Bisphosphonates (BPs) are a class of medications used for the treatment of osteoporosis. Nitrogen-containing BPs (N-BPs) are more potent than non-nitrogenous BPs in terms of their effects on osteoporosis. We examined the effects of N-BPs on osteoporosis in patients included in a large population-based cohort study. Based on the National Health Insurance Research Database of Taiwan, we identified 1258 patients with osteoporosis who had received N-BP treatment from 2005 through 2010. During the retrospective observation period, N-BP users had significantly higher incidence rates of hypertension, acute ischemic stroke, atrial fibrillation (Af), and congestive heart failure (CHF), and lower rates of hyperlipidemia than patients who did not use N-BPs. Overall, N-BP users had a higher incidence of cardiovascular events at the end of the follow-up period. After adjustment for age, sex, and comorbidities, the risk of developing cardiovascular events was significantly high for patients using N-BPs. Patients who received N-BP therapy also had a higher risk of Af and CHF than those who did not during the five-year follow-up period. We provide evidence that patients with osteoporosis using N-BP therapy have an increased risk of CHF and Af. This potential risk should be weighed against the reduction in the risk of osteoporotic fractures. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Randomized controlled trials (RCTs) in the field of diabetes have limitations inherent to the fact that design, setting, and patient characteristics may be poorly transferrable to clinical practice. Thus, evidence from studies using routinely accumulated clinical data are increasingly valued. We herein describe rationale and design of the DARWIN-T2D (DApagliflozin Real World evIdeNce in Type 2 Diabetes), a multicenter retrospective nationwide study conducted at 50 specialist outpatient clinics in Italy and promoted by the Italian Diabetes Society. The primary objective of the study is to describe the baseline clinical characteristics (particularly HbA1c) of patients initiated on dapagliflozin from marketing authorization approval to the end of 2016. Secondary and exploratory objectives will evaluate the changes in glycaemic and extraglycaemic efficacy parameters after initiation of dapagliflozin or after initiation of comparator glucose lowering medications (DPP-4 inhibitors, gliclazide extended release, and long-acting GLP-1 receptor agonists). An automated software will extract relevant data from the same electronic chart system at all centres, thereby minimizing data treatment and human intervention. The study is expected to collect an enormous dataset of information on dapagliflozin- and comparator-using patients. After study completion, the Italian Diabetes Society will launch an open crowdsourcing call on the DARWIN-T2D database, challenging diabetes researchers to apply their ideas and approaches to address new unmet needs and knowledge gaps in diabetes. We believe this will move DARWIN-T2D to the next generation of real world studies.

    Background: Survival rates after curative surgery for gastric cancer are disappointing. Therefore adjuvant therapeutic strategies are required. Aim: To analyze survival and side effects of treatment among gastric cancer patients treated with adjuvant chemoradiotherapy after curative resection of gastric adenocarcinoma. Material and methods: Retrospective review of medical records of 74 patients aged 20 to 74 years, treated with complete resection of gastric adenocarcinoma followed by adjuvant chemo radiation. Survival analysis was based on the records and information from the National Mortality Registry. Results: Five years survival fluctuated from 50% among patients in stage 1B to 25% among those is stage IV. Significant acute toxicity was observed in 23 patients (31%). No patients died due to acute toxicity. Eleven patients (16.4%) developed significant late toxicity, with two possible deaths related to treatment. Conclusions: Postoperative chemoradiotherapy is feasible in our experience. Continuos infusion of 5- fluoruracil is recommended to reduce toxicity

    The objective of this 10 year, retrospective study is to evaluate the indications for the removal of titanium miniplates following osteosynthesis in maxillofacial trauma and orthognathic surgery. All patients who had miniplates placed in a Regional Oral and Maxillofacial Department between January 1998 and October 2007 were included. The following variables were recorded: patient gender and age, number of plates inserted, indications for plate placement, location of plates, number and location of plates removed, indications for plate removal, time between insertion and removal, medical co-morbidities, and the follow-up period. During the 10 years of the study, 1247 titanium miniplates were placed in 535 patients. A total of 32 (3%) plates were removed from 30 patients. Superficial infection accounted for 41% of all plates removed. All complications were minor and most plates were removed within the first year of insertion. A low removal rate of 3% suggests that the routine removal of asymptomatic titanium miniplates is not indicated.

    Although the number of pregnancies in women with cardiac disease is increasing worldwide, there are few data concerning their clinical characteristics and peripartum outcomes. Using the Diagnosis Procedure Combination database between 2008 and 2014 in Japan, we retrospectively identified pregnant women who underwent high-risk delivery due to obstetric or non-obstetric comorbidities. We classified eligible women into those with pre-existing cardiac disease (cardiac disease group) and those with non-cardiac comorbidities (non-cardiac disease group) and compared their characteristics and peripartum outcomes. Of 94,364 women undergoing high-risk delivery at 556 hospitals, 857 (0.91%) had pre-existing cardiac disease (302, congenital heart disease; 190, arrhythmia; 176, valvular heart disease; 120, ischemic heart disease; 65, cardiomyopathy; 4, pericardial disease). Women in the cardiac disease group were more likely to be treated at university hospitals (51.1 versus 28.6%; p women with congenital heart disease (12.3%), valvular heart disease (12.5%), or cardiomyopathy (12.3%) than in women with arrhythmia (6.3%) or ischemic heart disease (5.8%). Multivariable logistic regression analysis showed a significant positive association between pre-existing cardiac disease and risk of heart failure (adjusted odds ratio, 24.7; 95% confidence interval, 17.6-34.6; p woman in the cardiac disease group died, whereas 18 women (0.02%) in the non-cardiac disease group did (p = 1.000). These findings suggest that pregnant women with pre-existing cardiac disease are at a higher risk of heart failure during the peripartum period than those with non-cardiac comorbidities.

    During pregnancy, the hyperdynamic physiology of circulation can exacerbate many cardiovascular disorders. Congestive heart failure (CHF) usually occurs during late pregnancy, which is significantly associated with a high level of maternal and neonatal morbidities and mortalities. The profile of women who develop peripartum CHF (PCHF) is unknown. We investigated the epidemiological profiles of PCHF. In this retrospective cohort study, PCHF patients were identified using International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes in Taiwan's National Health Insurance Research Database. Risk factors and obstetric outcomes were compared in women with and without PCHF. From 2,115,873 birth-mothers in Taiwan between 1997 and 2013, we identified 512 with PCHF (incidence: 24.20/10 5 ). More women with than without PCHF were older (≥ 35, 18.16% vs. 9.62%), and had more multifetal gestations (7.42% vs. 1.40%), gestational hypertension (HTN) (19.2% vs. 1.31%), and gestational diabetes mellitus (4.10% vs. 0.67%). After the analysis had been adjusted for confounders, the leading comorbidities associated with PCHF were structural heart diseases (adjusted odds ratio [aOR]: 67.21; 95% confidence interval [CI]: 54.29-83.22), pulmonary diseases (aOR: 13.12; 95% CI: 10.28-16.75), chronic HTN (aOR: 11.27; 95% CI: 6.94-18.28), thyroid disease (aOR: 9.53; 95% CI: 5.27-17.23), and gestational HTN (aOR: 5.16; 95% CI: 3.89-6.85). PCHF patients also had a higher rate of cesarean sections (66.41% vs. 34.46%; p outcomes, including maternal death. Our findings should benefit healthcare providers, and government and health insurance policy makers.

    Full Text Available Abstract Background The ongoing extended spectrum β-lactamase-producing Enterobacteriaceae (ESBL-PE pandemic has led to an increasing carbapenem use, requiring release of guidelines for carbapenem usage in France in late 2010. We sought to determine factors associated with changes in carbapenem use in intensive care units (ICUs, medical and surgical wards between 2009 and 2013. Methods This ward-level multicentre retrospective study was based on data from French antibiotic and multidrug-resistant bacteria surveillance networks in healthcare facilities. Antibiotic use was expressed in defined daily doses per 1000 patient-days. Factors associated with the reduction in carbapenem use (yes/no over the study period were determined from random-effects logistic regression model (493 wards nested within 259 healthcare facilities: ward characteristics (type, size…, ward antibiotic use (initial antibiotic use [i.e., consumption of a given antibiotic in 2009], initial antibiotic prescribing profile [i.e., proportion of a given antibiotic in the overall antibiotic consumption in 2009] and reduction in the use of a given antibiotic between 2009 and 2013 and regional ESBL-PE incidence rate in acute care settings in 2011. Results Over the study period, carbapenem consumption in ICUs (n = 85, medical (n = 227 and surgical wards (n = 181 was equal to 73.4, 6.2 and 5.4 defined daily doses per 1000 patient-days, respectively. Release of guidelines was followed by a significant decrease in carbapenem use within ICUs and medical wards, and a slowdown in use within surgical wards. The following factors were independently associated with a higher probability of reducing carbapenem use: location in Eastern France, higher initial carbapenem prescribing profile and reductions in consumption of fluoroquinolones, glycopeptides and piperacillin/tazobactam. In parallel, factors independently associated with a lower probability of reducing carbapenem use were

    Full text: To determine the overall survival and gastrointestinal toxicity for patients treated with salvage definitive chemo-radiotherapy after primary surgery for locoregional relapse of oesophageal carcinoma. A retrospective review of 525 patients who had a resection for oesophageal or oesophagogastric carcinoma at Princess Alexandra Hospital identified 14 patients treated with salvage definitive radiotherapy or chemo-radiotherapy, following localized recurrence of their disease. We analysed the patient and treatment characteristics to determine the median overall survival as the primary end point. Gastrointestinal toxicity was examined to determine if increased toxicity occurred when the stomach was irradiated within the intrathoracic radiotherapy field. The median overall survival for patients treated with curative intent using salvage definitive chemo-radiotherapy was 16 months and the 2-year overall survival is 21%. One patient is in clinical remission more than 5 years after therapy. Age <60 years old and nodal recurrence were favourable prognostic factors. Treatment compliance was 93% with only one patient unable to complete the intended schedule. Fourteen per cent of patients experienced grade 3 or 4 gastrointestinal toxicity. Salvage definitive chemo-radiotherapy should be considered for good performance status patients with oesophageal carcinoma who have a locoregional relapse after primary surgery. The schedule is tolerable with low toxicity and an acceptable median survival

    The aim of this study was to assess the frequency of appendiceal pathology in women undergoing surgery for mucinous ovarian neoplasm and to evaluate whether appendicectomy is necessary. This single-institution retrospective study reviewed prevalence of appendiceal lesions in all patients operated on at our institution from 2002 to 2013 with the final diagnosis of mucinous tumor of the ovary. Clinicopathological data were analyzed. One hundred twenty-three cases were identified. These included 45 (37%) benign mucinous ovarian neoplasms, 63 (51%) borderline, and 11 (9%) invasive mucinous ovarian tumors. In addition, 4 (3%) cases of metastatic tumors to the ovary were also identified. Appendiceal pathology was found in association with all types of mucinous ovarian tumors (benign, borderline, and malignant). In 24% of cases, appendix was macroscopically abnormal at the time of the surgery, prompting the surgical removal. Regardless of the gross findings, microscopic abnormality in the appendix was seen in 24% of all cases. The prevalence of significant occult microscopic appendiceal pathology, that is, when the appendix was grossly normal, was 6%. Given the prevalence of coexisting appendiceal pathology found in this study and the reported low rates of complications associated with the procedure, an appendicectomy is recommended in the management of all mucinous ovarian neoplasms.

    To analyze the impact of infectious complications and microbiology in the postoperative period after major oncologic neck surgeries. A retrospective study conducted in an oncology center, including all the consecutive patients who developed infectious complications after major neck cancer surgery, from October 2012 to May 2016 (44 months). Among other data, we collected TNM stage, ASA score, body mass index, comorbidities and habits, pre and postoperative hemoglobin levels, albumin serum levels, pre-surgical treatments, length of inpatient stay, isolated microbiological agents and the recorded complications and mortality rate. In the studied period, 761 major neck surgeries were performed. Of these, 96 patients had complications (12.6%). Pharyngocutaneous fistula (PCF) was the most frequent complication (56%) and nosocomial pneumonia was the most common systemic complication (23%). Pseudomonas aeruginosa was the principal microorganism of the 26 species isolated (15%). 12 deaths were registered. Using multiple linear regression we concluded that flap/cutaneous necrosis and PCF were complications with statistical significance that prolonged inpatient stay. The same complications had significant relative risk for more than 30 days of hospitalization. The postoperative period is critical for the successful treatment of head and neck oncology patients. PCF and flap/cutaneous necrosis were the principal complications which worsened the outcomes during this critical period. The early recognition and treatment of these complications is crucial.

    The use of continuous positive airway pressure (CPAP) perioperatively in bariatric surgery patients with obstructive sleep apnea (OSA) has been controversial. Although studies have demonstrated that CPAP use is safe in bariatric patients, prior studies have not shown improvement in outcomes in these patients. A retrospective review of patients who underwent bariatric surgery from 2005 to 2009 was performed. All patients underwent polysomnography preoperatively. Patient age, sex, BMI, comorbidities, polysomnogram data, type of bariatric procedure, length of hospital stay, and postoperative complications were reviewed. The Fisher exact test was used for statistical analysis. Among the 352 patients studied, 47 with apnea-hypopnea index (AHI) ≥5 did not receive CPAP postoperatively. A total of 7/47 (14.9 %) developed postoperative pulmonary complications. There were no non-pulmonary complications. Some 9/305 (2.95 %) with CPAP developed pulmonary complications. There were 26/305 patients with all-cause complications (8.52 %). The AHI was higher in the group receiving treatment. There was a statistically significant difference in pulmonary complications between patients with and those without treatment (p value 0.0002). The average length of stay was 3.0 and 3.2 days in treatment and comparison groups, respectively, a difference that did not reach statistical significance. Patients who did not receive CPAP postoperatively developed more pulmonary complications than those with CPAP, suggesting that CPAP might be beneficial in decreasing pulmonary complications in patients undergoing bariatric surgery. However, further investigation is warranted to better delineate other risk factors due to small sample size in our study group.

    Full Text Available Abstract Background Widespread literature on inequity in healthcare access and utilization has been published, but research on socioeconomic differences in waiting times is sparse and the evidence is fragmentary and controversial. The objective of the present study is the analysis of the relationship between individual socioeconomic level and waiting times for in-hospital elective surgery. Methods We retrospectively studied the waiting times experienced by patients registered on hospital waiting lists for 6 important surgical procedures by using the Hospital Discharge Database (HDD of the Piedmont Region (4,000,000 inhabitants in the North West of Italy from 2006 to 2008. The surgical procedures analyzed were: coronary artery by-pass (CABG, angioplasty, coronarography, endarterectomy, hip replacement and cholecystectomy. Cox regression models were estimated to study the relationship between waiting times and educational level taking into account the confounding effect of the following factors: sex, age, comorbidity, registration period, and Local Health Authorities (LHA as a proxy of supply. Results Median waiting times for low educational level were higher than for high educational level for all the selected procedures. Differences were particularly high for endarterectomy and hip replacement. For all considered procedures, except CABG, an inverse gradient between waiting times and educational level was observed: the conditional probabilities of undergoing surgery were lower among individuals with a low to middle level education than for individuals with a higher level of education after adjustment for sex, age, comorbidities, registration period, and LHAs. For most procedures the effect decreases over the follow up period. Conclusions The results of the study show evidence of inequalities in access to elective surgery in Italy. Implementation of policies aimed to promote national information initiatives that guarantee wider access to those

    The optimal time to initiate renal replacement therapy (RRT) in cardiac surgery-associated acute kidney injury (CSA-AKI) is unknown. Evidence suggests that the early use of RRT in critically ill patients is associated with improved outcomes. We studied the effects of time to initiation of RRT on outcome in patients with CSA-AKI. This was a retrospective observational multicenter study (24 Spanish hospitals). We analyzed data on 203 patients who required RRT after cardiac surgery in 2007. The cohort was divided into 2 groups based on the time at which RRT was initiated: in the early RRT group, therapy was initiated within the first 3 days after cardiac surgery; in the late group, RRT was begun after the 3rd day. Multivariate nonconditional logistic and linear regression models were used to adjust for potential confounders. In-hospital mortality was significantly higher in the late RRT group compared with early RRT patients (80.4 vs. 53.2%; p < 0.001; adjusted odds ratio of 4.1, 95% CI: 1.6-10.0). Also, patients in the late RRT group had longer adjusted hospital stays by 11.6 days (95% CI: 1.4-21.9) and higher adjusted percentage increases in creatinine at discharge compared with baseline by 67.7% (95% CI: 28.5-106.4). Patients who undergo early initiation of RRT after CSA-AKI have improved survival rates and renal function at discharge and decreased lengths of hospital stay. Copyright © 2011 S. Karger AG, Basel.

    Objectives To test whether cleft centres vary in their use of secondary cleft palate surgery, also known as revision palate surgery, and if so to identify modifiable hospital factors and surgeon factors that are associated with use of secondary surgery. Design Retrospective cohort study. Setting Forty-three paediatric hospitals across the USA. Patients Children with cleft lip and palate who underwent primary cleft palate repair from 1999 to 2013. Main outcome measures Time from primary cleft palate repair to secondary palate surgery. Results We identified 4939 children who underwent primary cleft palate repair. At 10 years after primary palate repair, 44% of children had undergone secondary palate surgery. Significant variation existed among hospitals (ppalate repair before 9 months of age was associated with an increased hazard of secondary palate surgery (initial HR 6.74, 95% CI 5.30 to 8.73). Postoperative antibiotics, surgeon procedure volume and hospital procedure volume were not associated with time to secondary surgery (p>0.05). Of the outcome variation attributable to hospitals and surgeons, between-hospital differences accounted for 59% (ppalate surgery exists depending on a child’s age at primary palate repair and the hospital and surgeon performing their repair. Performing primary palate repair before 9 months of age substantially increases the hazard of secondary surgery. Further research is needed to identify other factors contributing to variation in palate surgery outcomes among hospitals and surgeons. PMID:29479567

    Although ambulatory surgery offers patients convenience and reduced costs, same-day cancellation of ambulatory surgery negatively affects patient experiences and operational efficiency. We conducted a retrospective analysis to determine the frequency and reasons for same-day cancellations in an outpatient surgery center at a large academic tertiary referral center. Of 41 389 ambulatory surgical procedures performed, same-day cancellations occurred at a rate of 0.5% and were usually unforeseeable in nature. Focusing on foreseeable cancellations offers opportunities for enhanced patient satisfaction, improved quality of care, and systems-based practice improvements to mitigate cancellations related to areas such as scheduling or patient noncompliance.

    Full Text Available Recent results show a protective effect of tranexamic acid on death due to bleeding in patients with postpartum hemorrhage in low- and middle-resource countries. We quantify the association between early administration of tranexamic acid compared to late or no administration and severe acute maternal morbidity and blood loss among women suffering from persistent severe postpartum hemorrhage in a high-income country.We performed a nationwide retrospective cohort study in 61 hospitals in the Netherlands. The study population consisted of 1260 women with persistent postpartum hemorrhage who had received at least four units of red cells, or fresh frozen plasma or platelets in addition to red cells. A review of medical records was performed and cross-referenced with blood bank data. The composite endpoint comprised maternal morbidity (hysterectomy, ligation of the uterine arteries, emergency B-Lynch suture, arterial embolization or admission into an intensive care unit and mortality.247 women received early tranexamic acid treatment. After adjustment for confounding, odds ratio for the composite endpoint for early tranexamic acid (n = 247 versus no/late tranexamic acid (n = 984 was 0.92 (95% confidence interval (CI 0.66 to 1.27. Propensity matched analysis confirmed the absence of a difference between women with and without tranexamic acid. Blood loss after administration of first line therapy did not differ significantly between the two groups (adjusted difference -177 mL, CI -509.4 to +155.0.Our findings suggest that in a high-resource country the effect of tranexamic acid on both blood loss and the combined endpoint of maternal mortality and morbidity may be disappointing.

    Guidance on pre-operative fluids fasting policy continues to evolve. Current European guidelines encourage the intake of oral fluids up to 2 h before the induction of general anaesthesia. From October 2014, Torbay Hospital Day Surgery Unit commenced an unrestricted fluid policy, encouraging patients to drink clear fluids up until the time of transfer to theatre. The aim of this study was to assess the incidence of postoperative nausea and vomiting before and after the change to the unrestricted pre-operative clear oral fluids. Retrospective, before and after study. Single district general hospital between November 2013 and February 2016. A total of 11 500 patients on the day case pathway who were receiving either sedation, general anaesthesia, regional anaesthesia or their combination. The data from these patients were collected routinely. This number of patients represents approximately 78% of all patients before the change in fluids policy and 74% after the change. Exclusions were patients undergoing a termination of pregnancy, or patients undergoing community dental procedures, from whom patient experience data are not collected. Introduction of a change to the day surgery pathway policy permitting unrestricted clear oral fluids preoperatively until transfer to theatre (from October 2014). Incidence of postoperative nausea and vomiting. The rates of nausea within 24 h postoperatively were 270/5192 (5.2%) when patients could not drink within 2 h of surgery, and 179/4724 (3.8%) when patients could drink up until surgery, a relative rate (95% confidence interval) of 0.73 (0.61 to 0.88), P = 0.00074. The corresponding rates of vomiting were 146/5186 (2.8%) and 104/4716 (2.2%), a relative rate (95% confidence interval) of 0.78 (0.61 to 1.00), P = 0.053. Our data suggest that the liberal consumption of clear fluids before the induction of scheduled day case anaesthesia reduced the rates of postoperative nausea and vomiting.

    Adverse events (AEs) are a major concern in surgery, but the evidence in cardiac surgery is limited, especially on the contributory factors. According to the data of the National Outcomes Program, a unit was selected to conduct a mixed methods investigation into the incidence, type, and cause of AE, given its mortality rate that was double the national average on coronary artery bypass grafting, valve reparation, and replacement. A retrospective investigation on the performance of a cardiac surgery, combining the routinely collected data on process and outcome measures with a 2-stage structured review of 280 medical records performed by 3 expert clinicians, with the support of a methodologist. At least one risk had been verified in 137 of 280 cases (48.9%, 95% CI, 43.1-54.8). The total number of AE was 42, with an incidence of 15% (95% CI, 10.8-20.2) and a preventability of 80.9% (95% CI, 69.1-92.8). In 11.9% of AE, the consequence is death, disability in 40.5%, and extended hospital stay in 69% of the cases. Adverse events are associated with problems in care management at the ward (89/137, 64.9%, 95% CI, 56.9-72.9), followed by surgical complications (46/137, 33.6%, 95% CI, 25.7-41.5) and infection/sepsis (32/137, 23.4%, 95% CI, 16.3-30.4). An active error was made by the health care workers in 31 of 42 cases with AE, either during the decision making or during the execution of an action. A total of 36 AEs were due to deficiencies attributed to organizational factors and 31 were linked to poor teamwork. The mixed methods approach demonstrated how a deep understanding of AE and poor performance may emerge thanks to the combination of routinely available data and experts' evaluations. The main limitation of this study is its focus on the cardiac surgery rather than on the entire process of care. The evaluation could have been integrated with on-site observations and the analysis of reported incidents. © 2017 John Wiley & Sons, Ltd.

    A retrospective analysis of presurgical clinical picture and blood pressures of 34 patients with histologically verified pheochromocytoma. Assessment of clinical state, blood pressure and prognosis in the course of patients control hospitalizations from 2001 to 2002. The study was designed as a synoptic one, based on a retrospective analysis of 34 patients records with histologically verified pheochromocytoma (26 women and 8 men). Our assessments of clinical symptomatology, maximum paroxysmal hypertension values, average blood pressure values in patients with persistent arterial hypertension, arterial hypertension grade and circadian index were based on patients records. Patients epinephrectomies were followed during their control hospitalizations to assess their clinical state. Their blood pressures were evaluated by means of their circadian monitoring. From the 34 patients, 21 were diagnosed with solitary pheochromocytomas. The circadian index persistence analysis prior to the surgery was associated with circadian blood pressure monitoring in 21 patients. It was lost in 57% of patients. During their control hospitalization as many as 82% of patients preserved their circadian blood pressure variability with a more than 10% decrease in the night time, 5 patients did not preserve their circadian blood pressure variability. Seven from the original 34 patients died: Three of them died from their primary disease, one 63-year old man died from shock following tumour extirpation. The death of other 3 patients was not associated with their primary disease. Long-lasting survival of patients with pheochromocytoma after surgical treatment--except for those with malignant disease--was demonstrated. Although our assessment of the resulting treatment effects was positive, a long-term follow-up is inevitable because of a difficult pathologic-anatomical verification of the malignant nature of the disease as well as of the risk of tumour relapse assessment.

    Bariatric patients are often candidates for plastic surgery. However, the rate of postbariatric procedures is not known. The aim of this study was to analyze the rate of plastic surgery, and factors related to surgery, in bariatric patients. University hospital, France. This was a cohort study based on administrative data. All adult patients who received bariatric surgery in France between 2007 and 2013 were included to estimate the rate of plastic surgery and related predictive factors. Data are reported according to the reporting of studies conducted using observational routinely collected data guidelines for observational studies on administrative data. Among the 183,514 patients who underwent bariatric surgery in the study period, 23,120 plastic surgeries were performed on 17,695 patients, including abdominoplasty (62%), dermolipectomy of the upper or lower limbs (25%), and reconstruction of the breast (14%). The rates of plastic surgery were 13%, 18%, and 21% at 3, 5, and 7 years post-bariatric surgery, respectively. Multivariate analysis revealed that patients who had a biliopancreatic diversion or a gastric bypass had a hazard ratio of 2.67 and 2.67 for subsequent plastic surgery, respectively, compared with patients who had adjustable gastric banding. Women had a 2-fold probability of surgery compared with men (hazard ratio 2.02). Important variability in the rate of surgery was found among different hospitals; rates ranged from 6.1% to 41.3% at 5 years. This study showed that 21% of bariatric patients undergo plastic surgery. Large variability exists among hospitals, suggesting that several unmeasured factors may limit access to contouring surgery. Copyright © 2018. Published by Elsevier Inc.

This has led to a dramatic change in the postoperative condition of these patients, facilitating early ambulation and easier management of postoperative pain. However, empirical evidence on postoperative pain management after TS is limited. The aims of this study were to determine the efficacy and adequacy of postoperative analgesic medications and to simplify the choice of additional drugs based on a numerical rating scale (NRS.Materials and methods: A retrospective study of patients who underwent TS was performed to evaluate postoperative pain, analgesia requirements, and the number of drugs needed during the perioperative period based on the NRS score.Results: Of the 524 patients, mild pain was noted in 87% patients on the day of the operation and in 75.6% patients on ambulation. The mean NRS score was 1.83±1.49 on the day of the operation and 2.73±1.75 on ambulation. An NRS score of 3 on both the day of operation and on ambulation was defined as the necessary condition for improved pain management. Multivariate analysis showed that high surgical stress significantly influenced pain scores. Reduction in pain with an NRS score of ≥1 was significant with the addition of pentazocine hydrochloride (p<0.01 and flurbiprofen (p<0.01. Interestingly, the addition of tramadol was borderline efficacious (p=0.05 in patients with an NRS score of >3 on ambulation.Conclusion: A small number of patients have moderate-to-severe pain after TS. Tramadol demonstrated borderline efficacy in controlling postoperative intense pain with an NRS score of ≥3. Keywords: tramadol, thoracoscopic

    The purpose of this retrospective study was to evaluate the 4-year outcome of endodontic microsurgery using two different magnification devices. One-hundred and two teeth in 65 patients were included according to specific selection criteria. Endodontic surgery was performed under surgical microscope as magnification device in 63 teeth in 36 patients, while 39 teeth in 29 patients were treated under magnifying loupes. Thirteen patients did not attend the 4-year follow up. The overall success rate on a patient basis was 91.7% at the 1-year and 90.5% at the 4-year follow up for the group using loupes, while for the group using microscope it was 91.4% at the 1-year and 93.3% at the 4-year follow up. The relative risk was 2.07 (95% confidence interval: 0.31, 13.95) in favour of the group in which microscope was used. No statistically significant difference was found in the treatment outcomes relating to the type of magnification device. © 2011 The Authors.

In this retrospective review of hip replacement surgery patients, BMI classification was a predictor of early postoperative complications. Although the exact underlying mechanisms are still not clear, these results are consistent with the obesity paradox, in which obesity or its correlates provide some form of protection.

    Background: Differentiating between septic and aseptic joint prosthesis may be challenging, since no single test is able to confirm or rule out infection. The choice and interpretation of the panel of tests performed in any case often relies on empirical evaluation and poorly validated scores. The "Combined Diagnostic Tool (CDT)" App, a smartphone application for iOS, was developed to allow to automatically calculate the probability of having a of periprosthetic joint infection, on the basis of the relative sensitivity and specificity of the positive and negative diagnostic tests performed in any given patient. Objective: The aim of the present study was to apply the CDT software to investigate the ability of the tests routinely performed in three high-volume European centers to diagnose a periprosthetic infection. Methods: This three-center retrospective study included 120 consecutive patients undergoing total hip or knee revision, and included 65 infected patients (Group A) and 55 patients without infection (Group B). The following parameters were evaluated: number and type of positive and negative diagnostic tests performed pre-, intra- and post-operatively and resultant probability calculated by the CDT App of having a peri-prosthetic joint infection, based on pre-, intra- and post-operative combined tests. Results: Serological tests were the most common performed, with an average 2.7 tests per patient for Group A and 2.2 for Group B, followed by joint aspiration (0.9 and 0.8 tests per patient, respectively) and imaging techniques (0.5 and 0.2 test per patient). Mean CDT App calculated probability of having an infection based on pre-operative tests was 79.4% for patients in Group A and 35.7 in Group B. Twenty-nine patients in Group A had > 10% chance of not having an infection, and 29 of Group B had > 10% chance of having an infection. Conclusion: This is the first retrospective study focused on investigating the number and type of tests commonly performed

    Full Text Available Endocrine therapy (ET is one of the main systemic treatments for patients with breast cancer. To our knowledge, few studies have addressed the performance of ET or relevant influencing factors in cancer treatment in China. By retrospectively analyzing the clinicopathological data on breast cancer collected from representative hospitals of 7 traditional areas in China in one random month from each year between year 1999 and 2008, we found that: 1 The rate of the use of hormone receptor (HR testing was 83.8% (3529/4211, with the estrogen receptor-positive (ER+ rate and/or the progesterone receptor-positive (PR+ rate being 67.9% (2395/3529, and the ER-PR rate being 32.1% (1134/3529. 2 Of the 1599 patients who had received ET, 999 patients (58.3% were premenopausal while 600 (41.7% were postmenopausal; 1598 patients received adjuvant hormonal therapy (AHT, whereas only 1 patient received palliative therapy. The medications mainly administered to patients were anti-estrogen agents (80.3% [1283/1598], followed by AIs (15.5% [248/1598]. Of the 1598 patients receiving AHT, 1416 patients (88.6% were positive for ER and/or PR, while 75 (4.7% were negative for both and 108 patients (6.7% had unknown HR status. The ratio of the use of endocrine therapy for breast cancer patients with ER+ and/or PR+ status was 60.0% (1416/2395. 3 Results from the logistic regression analysis revealed that geography, occupations, and history of chemotherapy and surgery were dependent factors affecting the application of ET in breast cancer treatment in China (P<0.001. In conclusion, the use of ET on Chinese women with breast cancer is increasingly and gradually accounted into the standardized process. Economic status, occupations, and history of chemotherapy and surgery were key factors affecting the application of ET. People residing in developed areas, engaging in mental labour, having history of chemotherapy and surgery are susceptible to accept ET.

    Anterior cervical spine procedures have been associated with satisfactory outcomes. However, the occurrence of troublesome complications, although uncommon, needs to be taken into consideration. The purpose of our study was to assess the actual incidence of anterior cervical spine procedure-associated complications and identify any predisposing factors. A total of 114 patients undergoing anterior cervical procedures over a 6-year period were included in our retrospective, case-control study. The diagnosis was cervical radiculopathy, and/or myelopathy due to degenerative disc disease, cervical spondylosis, or traumatic cervical spine injury. All our participants underwent surgical treatment, and complications were recorded. The most commonly performed procedure (79%) was anterior cervical discectomy and fusion (ACDF). Fourteen patients (12.3%) underwent anterior cervical corpectomy and interbody fusion, seven (6.1%) ACDF with plating, two (1.7%) odontoid screw fixation, and one anterior removal of osteophytes for severe Forestier's disease. Mean follow-up time was 42.5 months (range, 6-78 months). The overall complication rate was 13.2%. Specifically, we encountered adjacent intervertebral disc degeneration in 2.7% of our cases, dysphagia in 1.7%, postoperative soft tissue swelling and hematoma in 1.7%, and dural penetration in 1.7%. Additionally, esophageal perforation was observed in 0.9%, aggravation of preexisting myelopathy in 0.9%, symptomatic recurrent laryngeal nerve palsy in 0.9%, mechanical failure in 0.9%, and superficial wound infection in 0.9%. In the vast majority anterior cervical spine surgery-associated complications are minor, requiring no further intervention. Awareness, early recognition, and appropriate management, are of paramount importance for improving the patients' overall functional outcome.

    Changes in medical education have resulted in less available time for plastic surgery, which might jeopardise the availability of plastic surgery for patients. The aims of this study were to investigate the level of knowledge within and attitudes towards plastic surgery among medical students, and find predictors for a wish to pursue a career in plastic surgery. A previously used questionnaire was sent to all clinical medical students. Law students were used as a control group. Thirty per cent of all clinical medical students in the country responded. The majority of students considered education in plastic surgery valuable/very valuable and 23% were considering it as a career. Nonetheless, about half of the students were unaware of the plastic surgical education at their faculty and reported non-academic sources of learning. Only 44% of medical students were able to name five common plastic surgical procedures and 8% were unable to name any. Law students were superior to medical students in the task (p = 0.005). Forty-two per cent of medical students were successful in indicating on which body parts plastic surgeons operate, whereas law students were less successful (p = 0.001). Male gender and positive valuing of clinical attachment could predict a wish for a career in plastic surgery. In some aspects, medical students are only as knowledgeable as their non-medical peers. These results call for higher quality plastic surgery teaching, to secure referral of the correct patients and successful specialist recruitment to plastic surgery.

    Bariatric surgery leads to significant weight loss with reduced morbidity and mortality. However, excess skin as a consequence of weight loss represents a major problem, impacting upon patient's functionality with potential negative effects on weight loss. We evaluated the effect of body-contouring surgery on weight-loss maintenance following bariatric surgery. We undertook a retrospective analysis of patients undergoing Roux-en-Y gastric bypass (RYGB) +/- body-contouring surgery (BC). The control group (n = 61) received RYGB, the test group (n = 30) received RYGB+BC 12 to 18 months after bariatric surgery. Each RYGB+BC patient was matched to two control patients for age, sex, glycaemic status, and weight on day of surgery. Per cent weight loss (%WL) was calculated at 3, 6, 12, 24, 36, 48, and 60 months post-RYGB for both groups. The %WL was similar at 3, 6, and 12 months post-RYGB. At 24 months, %WL was 35.6% in the RYGB+BC group and 30.0% in the RYGB group (P RYGB+BC group maintained their weight loss (%WL 33.0%), in contrast, the RYGB gained weight (%WL = 27.3%, P RYGB+BC vs RYGB) at 48 months (%WL 30.8% vs 27.0%) and at 60 months (%WL 32.2% vs 22.7%, P < 0.05). Our results suggest patients who undergo body contouring after bariatric surgery are able to lose significantly more weight and maintain weight loss at five years of follow up compared to those undergoing bariatric surgery alone. © 2017 The American Society for Aesthetic Plastic Surgery, Inc.

    Genetic predisposition is involved in only 10% of patients with breast cancer. This study was to evaluate the impact of prophylactic surgery. This is a retrospective study of 61 patients who received prophylactic breast surgery. Data collection was carried out through the computer file of the ICO. The inclusion criteria were: patients who benefited from a bilateral prophylactic mastectomy. There were no exclusion criteria. Patients received a satisfaction questionnaire to complete. Our study included 61 patients, 67% had a history of breast cancer. Bilateral prophylactic surgery was performed in 40 patients. It was made an average of two interventions, 44.3% of them presented postoperative complications, 18% recovery. Forty-three patients were satisfied with the medical information before surgery. The end result matched the expectations of 54.4% and 67.4% of patients would be ready to start. It was found pain associated with breast surgery in 56.5% of patients and almost half reported a change in their sexual life. Prophylactic mastectomy is the most effective technique to prevent the risk of breast cancer. The consequences of such an action are important. It is necessary to better select patients who would benefit most from this type of surgery. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    To assess morbidity and mortality associated with oral and maxillofacial surgery procedures requiring general anesthesia among children with aspiration tendency requiring enteral feeding. A retrospective chart review was conducted of children surgically treated under general anesthesia by the oral and maxillofacial surgery service at the Hospital for Sick Children in Toronto, Canada. Medical and dental records over a 9-year period (January 1, 2000 to January 1, 2010) were reviewed. Data were collected on demographics, primary illness, coexisting medical conditions, procedures performed, medications administered, type of airway management used, duration of general anesthesia, American Society of Anesthesiologists' physical status classification and adverse events. During the period reviewed, 28 children underwent 35 oral and maxillofacial surgery procedures under general anesthesia. The mean patient age was 12 years (range 4-17 years). No deaths occurred. Of the 35 surgeries, 10 (29%) were associated with at least 1adverse event. Adverse events included 1incident of respiratory distress, 2incidents of fever, 5incidents of bleeding, 1incident of seizure and 4incidents of oxygen saturation below 90% for more than 30s. Children with a history of aspiration tendency that necessitates enteral feeding, who undergo oral and maxillofacial surgery under general anesthesia, are at increased risk of morbidity. Before initiating treatment, the surgeon and parents or guardians of such children should carefully consider these risks compared with the anticipated benefit of surgery.

    Macroglossia is the commonest symptom of Beckwith-Wiedemann syndrome (BWS) and sometimes requires surgical tongue reduction for cosmetic, feeding, drooling and speech problems. We retrospectively reviewed the perioperative course of 14 BWS patients. The subjects were children who underwent tongue reduction surgery or glossopexy between 1994 and 2008 at Osaka Medical Center for Maternal & Child Health. The median age was 18 months, and the median weight was 12.2 kg at the time of surgery. One patient had the trachea intubated and another had tracheostomy to keep airway patency. Other 12 patients had no artificial airway and were premedicated with midazolam or diazepam and had the trachea intubated after induction with sevoflurane and nitrous oxide in oxygen. Only one patient developed difficult mask ventilation for which a nasal airway was applied. No patients demonstrated difficult intubation. All without preoperative artificial airway were extubated in the OR after the surgery. One patient demonstrated hypoglycemia. Airway compromise in the two patients who was intubated or had tracheostomy prior to surgery was not alleviated by the surgery. Airway disorder was not alleviated by tongue reduction surgery or glossopexy.

    Full Text Available Background Our study aimed to compare the outcomes of surgical treatment of tongue cancer patients in three different age groups. Methods From 2004 to 2013, we retrospectively analyzed the clinical data of 1,712 patients who were treated in the four institutions constituting the Chang Gung Memorial Hospitals (CGMH. We divided and studied the patients in three age groups: Group 1, younger (<65 years; Group 2, young old (65 to <75; and Group 3, older old patients (≥75 years. Results Multivariate analyses determined the unfavorable, independent prognostic factors of overall survival to be male sex, older age, advanced stage, advanced T, N classifications, and surgery plus chemotherapy. No significant differences were found in adjusted hazard ratios (HR of death in early-stage disease (stage I–II among Group 1 (HR 1.0, Group 2 (HR 1.43, 95% confidence interval (CI [0.87–2.34], p = 0.158, and Group 3 (HR 1.22, 95% CI [0.49–3.03], p = 0.664 patients. However, amongst advanced-stage patients (stage (III–IV, Group 3 (HR 2.53, 95% CI [1.46–4.38], p  = 0.001 showed significantly worse survival than the other two groups after other variables were adjusted for. Fourteen out of 21 older old, advanced-staged patients finally died, and most of the mortalities were non-cancerogenic (9/14, 64.3%, and mostly occurred within one year (12/14, 85% after cancer diagnosis. These non-cancer cause of death included underlying diseases in combination with infection, pneumonia, poor nutrition status, and trauma. Conclusions Our study showed that advanced T classification (T3–4, positive nodal metastasis (N1–3 and poorly differentiated tumor predicted poor survival for all patients. Outcome of early-stage patients (stage I–II among three age groups were not significantly different. However, for advanced-stage patients (stage III–IV, the older old patients (≥75 had significantly worse survival than the other two patient groups. Therefore, for early

    Many adverse events occur due to poor communication between surgical and anesthesia unit personnel. The aim of this study was to identify strategies to reduce risks unveiled by a national survey on patient safety. During 2011-2015, specially trained survey teams visited the surgery departments at Swedish hospitals and documented routines concerning safety in abdominal surgery. The reports from the first seventeen visits were reviewed by an independent group in order to extract findings related to routines in communication between anesthesia and surgical unit personnel. In general, routines regarding preoperative risk assessment were safe and well- coordinated. On the other hand, routines regarding medication prior to surgery, reporting between the different units, and systems for reporting and providing feedback on adverse events were poor or missing. Strategies with highest priority include: 1. a uniform national health declaration form; 2. consistent use of admission notes; 3. systems for documenting all important medical information, that is accessible to everyone; 4. a multidisciplinary forum for the evaluation of high-risk patients; 5. weekly and daily scheduling of surgical programs; 6. application of the WHO check list; 7. open dialog during surgery; 8. reporting based on SBAR; 9. oral and written reports from the surgeon to the postoperative unit; and 10. combined mortality and morbidity conferences. One repeatedly occurring hazard endangering patient safety was related to communication between surgical and anesthesia unit personnel. Strategies to reduce this hazard are suggested, but further research is required to test their effectiveness.

    The need for nonobstetric abdominal surgical interventions in pregnant females arises periodically in practice and can be a source for concern for both the patient and the surgeon because of the risk of adverse outcome. To determine the indications for, and assess maternal and fetal outcome following nonobstetric abdominal surgeries in Jos University Teaching Hospital. This was a retrospective cross-sectional study analyzing clinical records of pregnant women, who had nonobstetric abdominal surgeries in Jos University Teaching Hospital between January 2007 and December 2011. Fifty patients had nonobstetric abdominal surgery during the study period (January 2007 to December 2011). The ages of the women ranged 15-49 years with a mean of 29 ± 8.13 years. Intraoperative findings in the patients were consistent with acute appendicitis in 43 (86%) patients, two patients (4%) had ruptured spleen while one patient each (2.0%) had a transverse colon injury, postoperative adhesion bands, ruptured uterus and urinary bladder, and mesenteric injury. One (2.0%) mother died after surgery. 38 (76%) had spontaneous deliveries, and there were 11 miscarriages (22%) and 1 perinatal death. The perinatal mortality rate was 0.093/1000 deliveries. The mean hospital stay was 5.52 days. Nonobstetric abdominal surgeries in pregnant women are an infrequent occurrence at Jos University Teaching Hospital but when they do occur, they are indicated by acute appendicitis in pregnancy.

    While plastic surgeons and plastic surgery residents aspire to leadership in academic plastic surgery, there is no well-established pathway. Plastic surgery residencies and program directors(PDs) were obtained from the AMA's FREIDA database. The division chief or department chair (academic head) of every academic plastic surgery program was identified. One internet-based survey was distributed to academic heads, another to PDs. 90 academic heads were identified, 35 of whom also serve as PD. 67 unique PDs were identified. There was a 51% academic head response rate and a 65% PD response rate. Academic plastic surgery is overwhelmingly administered by mid-career males. The average PD was appointed at age 45 and has served for 7 years. S/he was trained via the independent track, completed additional training in hand surgery, and is a full professor. S/he publishes 2-3 peer reviewed manuscripts per year and spends 9 hours-per-week in administration. The average academic head was appointed at age 45 and has held his/her position for 12 years. S/he was trained in the independent model, completed fellowship training, and is a full professor. S/he publishes 5 peer reviewed manuscripts per year and spends 12 hours-per-week involved in administration. PDs and academic heads serve non-overlapping roles. Few PDs will advance to the role of academic head. Successful applicants to the PD position often serve as an associate program director and are seen as motivated resident educators. In contrast, those faculty members selected for the academic head role are academically accomplished administrators with business acumen.

    Increasing rates of obesity have led to growing demand for bariatric surgery. This has implications for wait times, particularly in publicly funded programs. This study examined the impact of patient and operational factors on wait times in a multidisciplinary bariatric surgery program. A retrospective study was conducted involving patients who were referred to a tertiary care centre (University Health Network, Toronto Western Hospital, Toronto) for bariatric surgery between June 2008 and July 2011. Patient characteristics, dates of clinical assessments and records describing operational changes were collected. Univariable analysis and multivariable log-linear and parametric time-to-event regressions were performed to determine whether patient and operational covariates were associated with the wait time for bariatric surgery (i.e., length of preoperative evaluation). Of the 1664 patients included in the analysis, 724 underwent surgery with a mean wait time of 440 (standard deviation 198) days and a median wait time of 445 (interquartile range 298-533) days. Wait times ranged from 3 months to 4 years. Univariable and multivariable analyses showed that patients with active substance use (β = 0.3482, p = 0.02) and individuals who entered the program in more recent operational periods (β = 0.2028, p < 0.001) had longer wait times. Additionally, the median time-to-surgery increased over 3 discrete operational periods (characterized by specific program changes related to scheduling and staffing levels, and varying referral rates and defined surgical targets; p < 0.001). Some patients could be identified at referral as being at risk for longer wait times. We also found that previous operational decisions significantly increased the wait time in the program since its inception. Therefore, careful consideration must be devoted to process-level decision-making for multistage bariatric surgical programs, because managerial and procedural changes can affect timely

    Full Text Available Abstract Background Acute kidney injury is among the most serious complications after cardiac surgery and is associated with an impaired outcome. Multiple factors may concur in the development of this disease. Moreover, severe renal failure requiring renal replacement therapy (RRT presents a high mortality rate. Consequently, we studied a Spanish cohort of patients to assess the risk factors for RRT in cardiac surgery-associated acute kidney injury (CSA-AKI. Methods A retrospective case-cohort study in 24 Spanish hospitals. All cases of RRT after cardiac surgery in 2007 were matched in a crude ratio of 1:4 consecutive patients based on age, sex, treated in the same year, at the same hospital and by the same group of surgeons. Results We analyzed the data from 864 patients enrolled in 2007. In multivariate analysis, severe acute kidney injury requiring postoperative RRT was significantly associated with the following variables: lower glomerular filtration rates, less basal haemoglobin, lower left ventricular ejection fraction, diabetes, prior diuretic treatment, urgent surgery, longer aortic cross clamp times, intraoperative administration of aprotinin, and increased number of packed red blood cells (PRBC transfused. When we conducted a propensity analysis using best-matched of 137 available pairs of patients, prior diuretic treatment, longer aortic cross clamp times and number of PRBC transfused were significantly associated with CSA-AKI. Patients requiring RRT needed longer hospital stays, and suffered higher mortality rates. Conclusion Cardiac-surgery associated acute kidney injury requiring RRT is associated with worse outcomes. For this reason, modifiable risk factors should be optimised and higher risk patients for acute kidney injury should be identified before undertaking cardiac surgery.

    Full Text Available Abstract Background This retrospective study compared the clinicopathological results among three groups divided by time sequence to evaluate the impact of introducing laparoscopic surgery on long-term oncological outcomes for right-sided colon cancer. Methods From April 1986 to December 2006, 200 patients who underwent elective surgery with stage II and III right-sided colon cancer were analyzed. The period for group I referred back to the time when laparoscopic approach had not yet been introduced. The period for group II was designated as the time when first laparoscopic approach for right colectomy was carried out until we overcame its learning curve. The period for group III was the period after overcoming this learning curve. Results When groups I and II, and groups II and III were compared, overall survival (OS did not differ significantly whereas disease-free survival (DFS in groups I and III were statistically higher than in group II (P = 0.042 and P = 0.050. In group III, laparoscopic surgery had a tendency to provide better long-term OS ( P = 0.2036 and DFS ( P = 0.2356 than open surgery. Also, the incidence of local recurrence in group III (2.6% was significantly lower than that in groups II (7.4% and I (12.1% ( P = 0.013. Conclusions Institutions should standardize their techniques and then provide fellowship training for newcomers of laparoscopic colon cancer surgery. This technique once mastered will become the gold standard approach to colon surgery as it is both safe and feasible considering the oncological and technical aspects.

    Full Text Available Breast cancer is one of the primary indications for cryopreservation and subsequent autotransplantation of ovarian tissue. The safety of this fertility preservation method remains questionable, as the presence of disseminated breast tumor cells cannot yet be excluded in the ovarian autografts. We explored the prevalence of ovarian metastases among young breast cancer patients and determined risk factors for the development of ovarian metastases.Using the nationwide database of the Dutch Pathology Registry (PALGA, we identified a cohort of 2648 women with primary invasive breast cancer at age 5 cm and/or inflammatory carcinoma, we recommend a cautious approach to ovarian tissue autotransplantation.

    Staple line leakage after bariatric surgery can be treated by endoscopic placement of a self-expandable stent. The success rate of stent placement is generally high, but migration is a frequent adverse event that hampers successful treatment. The Niti-S Beta stent is a fully covered double-bump stent that was specifically designed to prevent migration. This study aimed to evaluate the effectiveness and adverse event rate of the Niti-S Beta stent. A retrospective study was performed in three high-volume bariatric centers. All consecutive patients between 2009 and 2016 who underwent placement of a Beta stent for staple line leakage were included. Primary outcome was resolution of the leakage; secondary outcome was the adverse event rate including migration. Thirty-eight patients were included. Twenty-five (66%) had resolution of the leakage. Success rate was higher in patients who were treated with implantation of a Beta stent as initial treatment (100%) than in patients who were treated with a stent after revisional surgery had failed (55%, p = 0.013). Migration occurred in 12 patients (32%). There were two severe adverse events requiring surgical intervention, including a bleeding from an aorto-esophageal fistula. The success rate and the migration rate of the Beta stent seem comparable to other stents in this retrospective study. Despite the novel double-bump structure of the stent, the migration rate does not seem to be decreased.

    To determine the impact of each cause of revision surgery in total hip arthroplasty during the period 2009-2013. To analyse the relationship between these causes with different variables. A study was conducted on 127 patients who had hip replacement revision surgery in our hospital during this period. Parameters, such as age, sex, date of primary arthroplasty, prosthetic replacement date, and main cause of the revision were recorded. Those revisions performed within 5 years after the primary arthroplasty were considered as early rescue. The most common cause of rescue was aseptic loosening in 38 (30%) followed by instability in 30 (24%). In terms of age at the time of rescue, statistically significant differences were found, with it being significantly higher in patients re-operated for a fracture. Differences in age at first surgery were found to be 7 years younger than those with late rescue (63.40) with respect to early (70.21). Similar results to ours have been observed in other published series, except for the higher incidence of instability in early rescue. This study demonstrates aseptic loosening and instability as the most frequent causes of revision surgery in our hospital. Age is a very influential factor in relation to longevity of primary arthroplasty. Complications were higher in when the primary hip replacement is implanted in older patients.

    The prevalence and costs of the obesity epidemic and obesity-related conditions, including diabetes mellitus, is consistently increasing worldwide. Bariatric medicine is attempting to address this with weight loss and exercise programmes, and with increasing frequency, various forms of bariatric surgery. There has been considerable success reported after bariatric surgery but not without. We describe 14 patients with orthostatic intolerance (OI) post bariatric surgery. We report on OI (postural dizziness, palpitations and fainting), the results of cardiovascular autonomic testing and the associated and/or causative findings as well as reviewing the literature to consider the possible mechanisms. Comprehensive autonomic testing revealed that 35.7% (Buchwald et al., 2004) of these patients fulfilled the criteria for the Postural Tachycardia Syndrome (PoTS), 57.1% (Cremieux et al., 2008) had low levels of basal BP and 42.9% (Cammisotto & Bendayan, 2007) patients were presyncopal and 14.3% (Billakanty et al., 2008) experienced syncope. We propose that the incidence of OI post-bariatric surgery is higher than considered, that certain cohorts may be more susceptible to complications, and that further research is needed to identify the prevalence and, ideally anticipate occurrence. With the increasing prevalence of obesity and required clinical interventions, further understanding of the pathophysiological processes causing autonomic dysfunction after bariatric interventions will aid management, which may differ in those with an underlying disposition to autonomic involvement, such as diabetics, in whom such procedures are increasingly used.

    Full Text Available Background: Condylar resorption as a cause of relapse after orthognathic surgery is well known. Several authors have presented evidence of the relation between orthognathic surgery and condylar remodeling and resorption. This study was done to appraise the condylar changes along with the form and function following orthognathic surgery, as well as to assess what factors may have contributed to the problems. Methodology: A diagnosis of progressive condylar resorption (PCR was made by comparison of preoperative and postoperative radiographs (cephalometric radiograms, as well as clinical evaluations. The radiographs were taken for each patient preoperatively and postoperatively, which include immediately after osteotomy, at 6 months and 24 months. Additional radiographs were taken when required. Then, preoperative and postoperative tracings were compared at 24 months postoperatively. Results and Conclusion: It can be concluded from this study that females of relative low age (<18 years appeared to be a high-risk factor for the occurrence of condylar alteration including PCR. A steep mandibular plane angle, the low facial height ratio (post/ant, and magnitude of surgery were also significantly related to the occurrence of condylar alteration, but the multivariance regression showed that these parameters had only limited value.

    Abdominal complications following cardiopulmonary bypass (CPB) procedures may have mortality rates as high as 25%. Advanced procedures such as ventricular assist devices, artificial hearts and cardiac transplantation are being increasingly employed, changing the complexity of interventions. This study was undertaken to examine the changing trends in complications and the impact of cardiac surgery on emergency general surgery (EGS) coverage. A retrospective review was conducted of all CPB procedures admitted to our ICU between Jan. 2007 and Mar. 2010. The procedures included coronary bypass (CABG), valve, combination (including adult congenital) and advanced heart failure (AHF) procedures. The records were reviewed to obtain demographics, need for EGS consult/procedure and outcomes. Mean age of the patients was 66 ± 8.5 years, 71% were male. There were 945 CPB procedures performed on 914 patients during this study period. Over 39 months, 23 EGS consults were obtained, resulting in 10 operations and one hospital death (10% operative mortality). CABG and valve procedures had minimal impact on EGS workload while complex cardiac and AHF procedures accounted for significantly more EGS consultations (p surgery, advanced technology has increased the volume of complex CPB procedures increasing the EGS workload. Emergency general surgeons working in institutions that perform advanced procedures should be aware of the potential for general surgical complications perioperatively and the resultant nuances that are associated with operative management in this patient population.

Moreover, the influence of surgery on weight evolution in the diabetic population was compared with that observed in a nondiabetic matched population. Methods. Among 970 patients who were operated on in our center since 2001, 81 patients were identified as type 2 diabetes. Laparoscopic adjustable gastric banding (GB, intervention type Mason (MA, gastric bypass (RYGB, and sleeve gastrectomy (SG were performed, respectively, in 25%, 17%, 28%, and 30% of this diabetic population. Results. The resolution rate of diabetes one year after surgery was significantly higher after SG than GB (62.5% versus 20%, P<0.01, but not significantly different between SG and RYGB. In terms of LDL-cholesterol reduction, RYGB was equivalent to SG and superior to CGMA or GB. Considering the other cardiovascular risk factors, there was no significant difference according to surgical procedures. The weight loss was not statistically different between diabetic and nondiabetic matched patients regardless of the surgical procedures used. Conclusion. Our data confirm that the efficacy of surgery to treat diabetes is variable among the diverse procedures and SG might be an interesting option in this context.

    This retrospective study evaluates the results of 41 consecutive hand and forearm operations in 19 patients with systemic sclerosis performed between 1985 and 2000. The mean age of the patients was 50 (14-84) years. Twenty-seven operations were elective and 14 were acute, carried out for skin breakdown and/or skin necrosis. One minor wound healing problem occurred in the elective group. In the acute group, seven of 14 operations healed uneventfully. Four patients had necrosis/infections after surgery, which required further surgery. Two patients had repeated wound infections. Another patient only healed after he stopped smoking. In systemic sclerosis, surgery performed electively does not seem to have increased difficulty with wound healing. Even larger operations, such as wrist arthrodesis or wrist replacement, can be performed safely. In acute cases with spontaneous skin breakdown and/or necrosis and/or critically ischaemic fingers, wound healing is more precarious and several procedures may be necessary to achieve skin healing.

    Conclusion: This retrospective case series describes, for the first time, the clinical outcomes in a series of patients treated with radiotherapy for bone hydatid disease. Although no direct comparison between the treatment groups could be made due to methodological limitations of the study design, this study indicates that well-designed prospective randomized controlled clinical trials assessing radiotherapy may be warranted in patients with inoperable hydatid disease of the bones.

    Full Text Available The association between type 1 diabetes and thyroid autoimmunity has been studied in various populations, but seldom on Taiwanese children and adolescents. Therefore, the aim of this study was to examine the incidence of autoimmune thyroid disorders in Taiwanese children and adolescent patients with type 1 diabetes, based on data from a nationwide, population-based, health claims database.Using Taiwan's National Health Insurance Research Database, we identified 3,652 patients with type 1 diabetes between 2000 and 2012. A comparison cohort was assembled, which consisted of five patients without type 1 diabetes, based on frequency matching for sex and 3-year age interval, for each patient with type 1 diabetes. Both groups were followed until diagnosis of thyroid disorders or the end of the follow-up period. Poisson regression models were used to calculate incidence rate ratios for the thyroid disorders between the type 1 diabetes cohort and the comparison cohort.Simple and unspecified goiter (International Classification of Diseases, 9th Revision, Clinical Modification [ICD-9-CM] code 240, thyrotoxicosis (ICD-9-CM code 242, unspecified hypothyroidism (ICD-9-CM code 244.9, and thyroiditis (ICD-9-CM code 245 showed significantly higher incidences in the type 1 diabetes cohort compared with the control cohort, with incidence rate ratios of 2.74, 6.95, 6.54, 16.07, respectively.Findings from this nationwide, population-based cohort study showed that the incidences of autoimmune thyroid disorders were significantly higher in Taiwanese children and adolescents with type 1 diabetes compared with those without the disease.

    2012-01-01

    Background Functional tricuspid regurgitation (TR) occurs in patients with rheumatic mitral valve disease even after mitral valve surgery. The aim of this study was to analyze surgical results of TR after previous successful mitral valve surgery. Methods From September 1996 to September 2008, 45 patients with TR after previous mitral valve replacement underwent second operation for TR. In those, 43 patients (95.6%) had right heart failure symptoms (edema of lower extremities, ascites, hepatic congestion, etc.) and 40 patients (88.9%) had atrial fibrillation. Twenty-six patients (57.8%) were in New York Heart Association (NYHA) functional class III, and 19 (42.2%) in class IV. Previous operations included: 41 for mechanical mitral valve replacement (91.1%), 4 for bioprosthetic mitral valve replacement (8.9%), and 7 for tricuspid annuloplasty (15.6%). Results The tricuspid valves were repaired with Kay's (7 cases, 15.6%) or De Vega technique (4 cases, 8.9%). Tricuspid valve replacement was performed in 34 cases (75.6%). One patient (2.2%) died. Postoperative low cardiac output (LCO) occurred in 5 patients and treated successfully. Postoperative echocardiography showed obvious reduction of right atrium and ventricle. The anterioposterior diameter of the right ventricle decreased to 25.5 ± 7.1 mm from 33.7 ± 6.2 mm preoperatively (P valve replacement in rheumatic heart disease is a serious clinical problem. If it occurs or progresses late after mitral valve surgery, tricuspid valve annuloplasty or replacement may be performed with satisfactory results. Due to the serious consequence of untreated TR, aggressive treatment of existing TR during mitral valve surgery is recommended. PMID:22490269

    2016-11-01

    The vast majority of studies published on robot-assisted thyroid surgery are South Korean. This study aims to assess the impact of certain anthropometric parameters on performing robot-assisted thyroid surgery on Caucasian patients. A total of 91 patients underwent robot-assisted surgery by the axillary approach in the Fifth Surgical Clinic, City Hospital Cluj-Napoca, between 2010 and 2015. Besides the specific clinical and pathological parameters, a series of anthropometric parameters and the postoperative occurrence of skin disorders in the cervical or subclavicular region were determined for each patient. There was an increase in dissection time and console time, which was directly proportional to the patients' body mass index. There were no statistically significant differences in the incidence of postoperative complications in patients with different body mass indices. The postoperative drainage volume was significantly higher in overweight or obese patients. The time needed to visualize the thyroid lodge was longer in patients with wider shoulders, and there was a negative correlation between neck length and console time. A statistically significant direct correlation was found between the clavicle length-neck length ratio and the duration of the entire intervention. There was no significant influence of any of these parameters on the duration of hospitalization or the occurrence of other postoperative complications. The nutritional status of the patients and the other anthropometric parameters influenced the duration and difficulty of the intervention, without affecting its safety in terms of intra- and postoperative- complications.

    Sun-Kyung Park

    Full Text Available Acute kidney injury (AKI after pediatric cardiac surgery is associated with high morbidity and mortality. Modifiable risk factors for postoperative AKI including perioperative anesthesia-related parameters were assessed. The authors conducted a single-center, retrospective cohort study of 220 patients (aged 10 days to 19 years who underwent congenital cardiac surgery between January and December 2012. The incidence of AKI within 7 days postoperatively was determined using the Kidney Disease: Improving Global Outcomes (KDIGO criteria. Ninety-two patients (41.8% developed AKI and 18 (8.2% required renal replacement therapy within the first postoperative week. Among patients who developed AKI, 57 patients (25.9% were KDIGO stage 1, 27 patients (12.3% were KDIGO stage 2, and eight patients (3.6% were KDIGO stage 3. RACHS-1 (Risk-Adjusted classification for Congenital Heart Surgery category, perioperative transfusion and fluid administration as well as fluid overload were compared between patients with and without AKI. Multivariable logistic regression analyses determined the risk factors for AKI. AKI was associated with longer hospital stay or ICU stay, and frequent sternal wound infections. Younger age (3 g/dl from preoperative level on POD1 was entered into the multivariable analysis, it was independently associated with postoperative AKI (OR, 6.51; 95% CI, 2.23-19.03 compared with no increase. This association was significant after adjustment with patient demographics, medication history and RACHS-1 category (hemoglobin increase >3g/dl vs. no increase: adjusted OR, 6.94; 95% CI, 2.33-20.69, regardless of different age groups and cyanotic or non-cyanotic heart disease. Prospective trials are required to evaluate whether correction of preoperative anemia and prevention of hemoconcentration may ameliorate postoperative AKI in patients who underwent congenital cardiac surgery.

    To study the anatomic and functional outcome of air descemetopexy in postcataract surgery Descemet's membrane detachment (DMD). Retrospective study. Setting: Institutional. Records of 112 patients who underwent air descemetopexy for postcataract surgery sight-threatening DMD at Aravind Eye Hospital, Pondicherry, between January 2013 and December 2015 were studied. Anatomical outcome refers to reattachment of the Descemet's membrane (DM). Functional outcome was given by the best-corrected visual acuity. The mean age was 66.47±8.46 (SD) years, the male to female ratio was 45:67. The incidence of DMD was more in extracapsular cataract extraction (0.26%) and manual small incision cataract surgery (0.11%) than phacoemulsification (0.04%) (p=0.005 and pair descemetopexy, 78 (71%) out of the 110 patients had DM reattachment. The complications noted after descemetopexy include persistent DMD (21.8%), corneal decompensation (7.3%), appositional angle closure (18%), pupillary block with air (2.7%) and uveitis (2.7%). Age, sex and timing of intervention did not influence the reattachment rate. Fifteen patients underwent repeat air descemetopexy for persistent DMD among whom nine (60%) had successful reattachment. Almost 75% of patients had vision better than 6/18 1 month after anatomically successful descemetopexy. Air descemetopexy is a safe and efficient modality of treatment of DMD and should be tried even in patients with severe DMD before planning a major surgery like endothelial keratoplasty. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Complex, oncologic surgery is an important component of resident education. Our objective was to evaluate the impact of resident participation in oncologic procedures on overall 30-day morbidity and mortality. A retrospective cohort analysis was performed using the National Surgical Quality Improvement Program Participant User Files for 2005-2009. Colorectal, hepatopancreaticobiliary, and gastroesophageal oncology procedures were included. Multivariate logistic regression was used to assess the impact of trainee involvement on 30-day morbidity and mortality after adjusting for potential confounders. A total of 77,862 patients were included for analysis, 53,885 (69.2%) involving surgical trainees and 23,977 (30.8%) without trainees. The overall 30-day morbidity was significantly higher in the trainee group [27.2 vs. 21%, adjusted odds ratio (AOR) 1.19, 95% confidence interval (CI) 1.15-1.24, p patients suffering one or more postoperative complications) (5.9 vs. 7.6%, AOR 0.79, 95% CI 0.68-0.90, p = 0.001). The overall 30-day morbidity was highest in the PGY 5 level (29%) compared to 24% for PGY 1 or 2 and 23% for PGY 3 (AOR per level increase 1.05, 95% CI 1.03-1.07, p surgery is associated with significantly higher rates of 30-day postoperative complications in NSQIP-participating hospitals; however, this effect is countered by overall lower 30-day mortality and improved rescue rate in preventing death among patients suffering complications.

    Osteoarthritis (OA) is the most common form of arthritis associated with an increased prevalence of type 2 diabetes mellitus (T2DM), however their impact on decreasing joint replacement surgery has yet to be elucidated. This study aimed to investigate if the combination of COX-2 inhibitor and metformin therapy in OA with T2DM were associated with lower the rate of joint replacement surgery than COX-2 inhibitor alone. In total, 968 subjects with OA and T2DM under COX-2 inhibitor and metformin therapy (case group) between 1 January to 31 December 2000 were selected from the National Health Insurance Research Database of Taiwan, along with 1936 patients were the 1:2 gender-, age-, and index year-controls matched without metformin therapy (control group) in this study. Cox proportional hazards analysis was used to compare the rate of receiving joint replacement surgery during 10 years of follow-up. At the end of follow-up, 438 of all enrolled subjects (15.08%) had received the joint replacement surgery, including 124 in the case group (12.81%) and 314 in the control group (16.22%). The case group tended to be associated with lower rate of receiving the joint replacement surgery at the end of follow-up than the control group (p = 0.003). Cox proportional hazards regression (HR) analysis revealed that study subjects under combination therapy with metformin had lower rate of joint replacement surgery (adjusted HR 0.742 (95% CI = 0.601-0.915, p = 0.005)). In the subgroups, study subjects in the combination metformin therapy who were female, good adherence (>80%), lived in the highest urbanization levels of residence, treatment in the hospital center and lower monthly insurance premiums were associated with a lower risk of joint replacement surgery than those without. Patients who have OA and T2DM receiving combination COX-2 inhibitors and metformin therapy associated with lower joint replacement surgery rates than those without and this may be attributable to combination

    To determine the suitability of amniotic membrane an bovine bone xenografts for the use in spinal surgery and anterior cranial for a generations. Fifteen patients with anterior cranial fossa defects and spinal bone fractures received bovine bone xenografts and 10 patients with meningomyeloceles received amniotic membranes (produced by the Malaysian National Tissue Bank) were analysed retrospectively. Clinical criterias like fever, signs of inflammation, breakdown of graft implant, non specific reaction to the nervous tissue were analysed haematological and radiologically. All patients who received the bovine grafts and amniotic membranes did not show any evidence of inflammation or fever. There were no graft implant breakdowns. There was no radiological or clinical evidence of specific or non specific reaction to the nervous tissue after 12-36 months followup Amniotic membranes and bovine xenografts may be used in the healing and reconstruction of spinal and cranial defects. Despite no evidence of rejection and infection after 36 months, a long term followup is still needed

    The aim of surgical approach in advanced ovarian cancer should be the complete removal of all visible disease. Our purpose was to compare perioperative features and postoperative complications, and secondarily oncological outcomes, between patients who underwent splenectomy and those who did not at the time of surgery. Thirty-three subjects underwent splenectomy, and we selected 99 controls with similar surgical characteristics but who did not undergo splenectomy. Data collected included perioperative details and follow-up data. Longer operating time (33 minutes longer; P = 0.02), larger estimated blood loss (812 mL more; P = 0.03), higher rate of intraoperative blood transfusions (78.8% vs 42.4%; P < 0.01), and intensive care unit stay (1.4 vs 0.5 days; P < 0.01) as well as higher pneumonia rate (2% vs 0%; P = 0.01) were observed in the splenectomy group. Disease-free and overall survival rates were 30.3% and 66.6%, respectively, in the splenectomy group, and 33.3% and 59.6%, respectively, in the control group. Splenectomy at the time of primary cytoreductive surgery for advanced ovarian cancer may contribute to achieve complete cytoreduction with low perioperative complication rate. This procedure seems to be an acceptable and rational intervention to increase the survival rates of those patients.

    Full Text Available It is perceived that patients with a history of frequent alcohol consumption require more opioids for postoperative pain control and experience less postoperative nausea and vomiting than patients without such a history. However, there is scarce evidence supporting this notion. The aim of this study was to assess association between frequent alcohol consumption and opioid requirement for postoperative pain control and occurrence of postoperative nausea and vomiting.The medical records for 4143 patients using intravenous patient-control analgesia with opioids after abdominal surgery between January 2010 and September 2013 were obtained, and associations were sought between the cumulative opioid consumption (in intravenous morphine equivalence per body weight (mg/kg in the first 2 days after abdominal operation and several demographic and clinical variables by multiple regression analysis. The association between the occurrence of postoperative nausea and vomiting and several demographic and clinical variables was also sought by multiple logistic regression analysis.Frequent alcohol drinking, among other previously reported factors, was associated with increased opioid consumption for postoperative pain control (p < 0.001. The estimate effect of frequent alcohol drinking was 0.117 mg/kg. Frequent alcohol drinking was also associated with decreased risks of postoperative nausea (odds ratio = 0.59, p = 0.003 and vomiting (odds ratio = 0.49, p = 0.026.Frequent alcohol drinking was associated with increased opioid consumption for postoperative pain control and decreased risks of postoperative nausea and vomiting after abdominal surgery.

    Background: in the therapy of brain metastases there has been a great progress in the last years. It was shown, that more aggressive therapies can not only extend the survival of the patients, but also improve quality of life. The major question of this study was, whether surgery or stereotactic radiotherapy with the linear accelerator show better results in behalf of the survival. Beside this major question many parameters regarding the patient or his primary cancer were examined. Methods: from the 1st of January 1995 until the 30th of June 2000 233 patients with one or more brain metastases have been treated in the Wagner Jauregg Landesnervenkrankenhaus Oberoesterreich (WJ LNKH OeO).

    Minimally invasive surgical techniques have been developed to minimize tissue damage, reduce narcotic requirements, decrease blood loss, and, therefore, potentially avoid prolonged immobilization. Thus, the purpose of the present retrospective study was to assess the safety and efficacy of a minimally invasive posterior approach with transforaminal lumbar interbody debridement and fusion plus pedicle screw fixation in lumbar spondylodiscitis in comparison to an open surgical approach. Furthermore, treatment decisions based on the patient´s preoperative condition were analyzed. 67 patients with lumbar spondylodiscitis treated at our department were included in this retrospective analysis. The patients were categorized into two groups based on the surgical procedure: group (MIS) minimally invasive lumbar spinal fusion (n = 19); group (OPEN) open lumbar spinal fusion (n = 48). Evaluation included radiological parameters on magnetic resonance imaging (MRI), laboratory values, and clinical outcome. Preoperative MRI showed higher rates of paraspinal abscess (35.5 vs. 5.6%; p = 0.016) and multilocular location in the OPEN group (20 vs. 0%, p = 0.014). Overall pain at discharge was less in the MIS group: NRS 2.4 ± 1 vs. NRS 1.6 ± 1 (p = 0.036). The duration of hospital stay was longer in the OPEN than the MIS group (19.1 ± 12 days vs. 13.7 ± 5 days, p = 0.018). The open technique is effective in all varieties of spondylodiscitis inclusive in epidural abscess formation. MIS can be applied safely and effectively as well in selected cases, even with epidural abscess.

    The objective of this study was to investigate the influence of oral contraceptives on the incidence rate of alveolar osteitis (AO) following the surgical extraction of both impacted mandibular third molars. This retrospective study reviewed the clinical records of patients who presented to the oral surgery clinic of a university school of dentistry for the extraction of impacted mandibular third molars. Using a database search, all patients were categorized by sex, age, occurrence of AO, and whether the females were taking oral contraceptives at the time of surgery. The patient was considered positive for AO if either one or both sockets developed AO. The incidence of AO among women taking oral contraceptives at the time of impacted mandibular third molar extraction differed significantly from that in the other patient groups. AO occurred in 37.9% (11/29) of females taking oral contraceptives, while only 8.9% (16/179) of females who were not taking oral contraceptives at the time of extraction developed AO. The total incidence of AO among females was 13.0% (27/208). The total incidence of AO among the 363 males and females presenting for mandibular third molar extractions was 13.8%. Females who are taking oral contraceptives at the time of impacted mandibular third molar extraction are at a higher risk of developing AO following extraction.

    Surgical resection is the main treatment for patients with non-small-cell lung cancer (NSCLC), but patients' long-term outcome is still challenging. The purpose of this study was to identify predictors of long-term survival in patients after lung cancer surgery. Patients who underwent surgery for NSCLC from January 1, 2006, to December 31, 2009, were enrolled into this retrospective cohort study. The primary outcome was the survival length after surgery. Predictors of long-term survival were screened with the multivariable Cox proportional hazard model. Postoperative follow-up was completed in 588 patients with a median follow-up duration of 5.2 years (interquartile range, 2.0-6.8). Two hundred ninety-one patients (49.5%) survived at the end of follow-up with median survival duration of 64.3 months (interquartile range, 28.5-81.6). The overall survival rates were 90.8%, 70.0%, and 57.1% at the end of the first, third, and fifth year after surgery, respectively. Limited resection (hazard ratio [HR], 1.46; 95% confidence interval [CI], 1.08-1.98; P = .013) and large tumor size (HR, 1.29; 95% CI, 1.17-1.42; P administration of dexamethasone and flurbiprofen axetil was associated with longer survival (compared to no use of both: adjusted HR, 0.57; 95% CI, 0.38-0.84; P = .005). Certain factors in particular perioperative dexamethasone and flurbiprofen axetil therapy may improve patients' long-term survival after surgery for NSCLC. Given the small sample size, these findings should be interpreted with caution, and randomized clinical trials are needed for further clarification.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

    Elderly patients with chronic nonresolving symptoms due to degenerative spine pathologies are prone to have poor surgical outcomes and hardware-related complications, especially following multilevel instrumented lumbar fusion surgeries. With intention of analyzing if teriparatide can be an effective adjunct therapy to surgical management, radiological outcomes are studied. Sixty-two elderly patients were divided into 2 similar groups. Group 1 (n = 30; mean age = 69.83 years; fusion levels = 137; screws = 269) had taken teriparatide (20 mcg SC injection, once daily) for a duration of 7.4 ± 2.4 months following surgery and Group 2 (n = 32; mean age = 70.38 years; fusion levels = 144; screws = 283) did not take teriparatide. Radiological evaluation was done to determine the state of postero lateral fusion mass and to investigate the incidence of pedicle screw loosening at 1-year follow-up. Unilateral or bilateral bridging bone formation across the transverse process of adjacent vertebras showing continuous trabeculation suggestive of solid fusion was obtained in 66.7% patients in the teriparatide group and 50% patients in the control group (P = 0.20). 13.4% of the total no. of screws showed signs of loosening in the teriparatide group, compared to 24.4% in the control group (P = 0.001). Percentage of patients achieving solid fusion following teriparatide use was found to be more than that of the control group. This difference may have clinical importance but was not statistically significant. However, teriparatide use was more significantly influential in reducing the incidence of subsequent pedicle screw loosening.

    Lumbar floating fusion occasionally causes postoperative adjacent segment disorder (ASD) at lumbosacral level, causing L5 spinal nerve disorder by L5-S1 foraminal stenosis. The disorder is considered to be one of the major outcomes of L5-S1 ASD, which has not been evaluated yet. The present study aimed to evaluate the incidence and risk factors of postoperative L5 spinal nerve disorder after lumbar interbody fusion extending to the L5 vertebra. We evaluated 125 patients with a diagnosis of spondylolisthesis who underwent floating fusion surgery with transforaminal lumbar interbody fusion with average postoperative period of 25.2 months. The patients were regarded as symptomatic with postoperative L5 spinal nerve disorder such as radicular pain/numbness in the lower limbs and/or motor dysfunction. We estimated and compared the wedging angle (frontal view) and height (lateral view) of the lumbosacral junction in pre- and postoperative plain X-ray images and the foraminal ratio (ratio of the narrower foraminal diameter to the wider diameter in the craniocaudal direction) in the preoperative magnetic resonance image. Risk factors for the incidence of L5 spinal nerve disorder were explored using multivariate logistic regression. Eight of the 125 patients (6.4%) were categorized as symptomatic, an average of 13.3 months after surgery. The wedging angle was significantly higher, and the foraminal ratio was significantly decreased in the symptomatic group (both P < 0.05) compared to the asymptomatic group. Multivariate logistic regression analysis of possible risk factors revealed that the wedging angle, foraminal ratio, and multileveled fusion were statistically significant. Higher wedging angle and lower foraminal ratio in the lumbosacral junction were significantly predictive for the incidence of L5 nerve root disorder as well as multiple-leveled fusion. These findings indicate that lumbosacral fixation should be considered for patients with these risk factors even

    To determine the effects of bariatric surgery on albuminuria in obese patients with type 2 diabetes mellitus. Retrospective analyses of clinical records of obese patients with type 2 diabetes mellitus who had either micro- or macroalbuminuria and had undergone various bariatric surgery were retrieved from a local hospital database. Their clinical data from follow-up appointments including albuminuria were analysed. Of the 46 subjects with type 2 diabetes mellitus, 15 subjects had diabetic nephropathy and had pre- and post-bariatric surgery urine albumin-to-creatinine ratio or urine protein-to-creatinine ratio data available for analysis; 13 out of the 15 subjects (86.7%) showed improvement of urine albumin-to-creatinine ratio or urine protein-to-creatinine ratio after surgery; 2 showed equivocal results; 9 of 13 subjects (69.2%) showed remission of diabetic nephropathy; 7 of these 9 patients had microalbuminuria before surgery, 2 had macroalbuminuria before surgery. There were significant improvements to glycosylated haemoglobin, fasting plasma glucose, blood pressure and body weight post surgery. The usage of insulin and oral medications dropped significantly post surgery for all subjects. This study shows that bariatric surgery significantly improves diabetic nephropathy in obese type 2 diabetes mellitus subjects. The results suggest that in our local type 2 diabetes mellitus patients, it is possible not only to improve metabolic parameters, but also to reverse what may be considered established microvascular complications by means of bariatric surgery.

    Full Text Available BACKGROUND: Thoracic surgeries including thoracotomy and VATS are some of the highest risk procedures that often lead to CPSP, with or without a neuropathic component. This retrospective study aims to determine retrospectively the prevalence of CPSP following thoracic surgery, its predicting risk factors, the incidence of neuropathic component, and its impact on quality of life. METHODS: Patients who underwent thoracic surgeries including thoracotomy and VATS between 01/2010 and 12/2011 at the First Affiliated Hospital, School of Medicine, Zhejiang University were first contacted and screened for CPSP following thoracic surgery via phone interview. Patients who developed CPSP were then mailed with a battery of questionnaires, including a questionnaire referenced to Maguire's research, a validated Chinese version of the ID pain questionnaire, and a SF-36 Health Survey. Logistic regression analyses were subsequently performed to identify risk factors for CPSP following thoracic surgery and its neuropathic component. RESULTS: The point prevalence of CPSP following thoracic surgery was 24.9% (320/1284 patients, and the point prevalence of neuropathic component of CPSP was 32.5% (86/265 patients. CPSP following thoracic surgery did not improve significantly with time. Multiple predictive factors were identified for CPSP following thoracic surgery, including age<60 years old, female gender, prolonged duration of post-operative chest tube drainage (≥ 4 days, options of post-operative pain management, and pre-existing hypertension. Furthermore, patients who experienced CPSP following thoracic surgery were found to have significantly decreased physical function and worse quality of life, especially those with neuropathic component. CONCLUSIONS: Our study demonstrated that nearly 1 out of 4 patients underwent thoracic surgery might develop CPSP, and one third of them accompanied with a neuropathic component. Early prevention as well as aggressive

    The benefits of cytoreductive surgery for uterine carcinosarcoma (UCS) are unknown. The objective of this study was to determine the impact of optimal surgery on advanced UCS patient survival. We performed a multi-institutional, retrospective study of women diagnosed with stage IIIIV UCS between 2007 and 2012. Data were obtained retrospectively from medical records, including demographic, clinicopathologic, treatment, and outcome information. Optimal cytoreductive surgery was defined as surgery resulting in a maximum residual tumor of ≤1cm. The Kaplan-Meier method was used to calculate progression-free survival (PFS) and overall survival (OS), and the Cox regression model was used to examine the impact of selected factors on survival. A total of 225 UCS patients (median age, 63years) were identified, including 136 (60%) with stage III and 89 (40%) with stage IV disease. Among these patients, 170 (76%) received optimal cytoreductive surgery. The median follow-up time was 19months. The median PFS was 11.5months (95% confidence interval [CI], 10.6-13.4) and 8.1months (95% CI, 5.1-9.5) for patients who received optimal and suboptimal cytoreductive surgery, respectively (P1cm was associated with worse OS while pelvic lymph node dissection was associated with improved OS. Optimal cytoreductive surgery and pelvic lymph node dissection are associated with improved OS in advanced UCS patients. Copyright © 2016 Elsevier Inc. All rights reserved.

Some studies have shown reduced surgical time, postoperative pain, time in the postanesthesia care unit (PACU, incidence of urinary retention, postoperative nausea, and more favorable cost-effectiveness with spinal anesthesia. Despite these results, the current literature has also shown contradictory results in between-group comparisons. Materials and methods: A retrospective analysis was performed by querying the electronic medical record database for surgeries performed by a single surgeon between 2007 and 2011 using procedural codes 63030 for diskectomy and 63047 for laminectomy: 544 lumbar laminectomy and diskectomy surgeries were identified, with 183 undergoing general anesthesia and 361 undergoing spinal anesthesia (SA. Linear and multivariate regression analyses were performed to identify differences in blood loss, operative time, time from entering the operating room (OR until incision, time from bandage placement to exiting the OR, total anesthesia time, PACU time, and total hospital stay. Secondary outcomes of interest included incidence of postoperative spinal hematoma and death, incidence of paraparesis, plegia, post-dural puncture headache, and paresthesia, among the SA patients. Results: SA was associated with significantly lower operative time, blood loss, total anesthesia time, time

    Posterior fossa ependymoma comprises two distinct molecular variants termed EPN_PFA and EPN_PFB that have a distinct biology and natural history. The therapeutic value of cytoreductive surgery and radiation therapy for posterior fossa ependymoma after accounting for molecular subgroup is not known. Four independent nonoverlapping retrospective cohorts of posterior fossa ependymomas (n = 820) were profiled using genome-wide methylation arrays. Risk stratification models were designed based on known clinical and newly described molecular biomarkers identified by multivariable Cox proportional hazards analyses. Molecular subgroup is a powerful independent predictor of outcome even when accounting for age or treatment regimen. Incompletely resected EPN_PFA ependymomas have a dismal prognosis, with a 5-year progression-free survival ranging from 26.1% to 56.8% across all four cohorts. Although first-line (adjuvant) radiation is clearly beneficial for completely resected EPN_PFA, a substantial proportion of patients with EPN_PFB can be cured with surgery alone, and patients with relapsed EPN_PFB can often be treated successfully with delayed external-beam irradiation. The most impactful biomarker for posterior fossa ependymoma is molecular subgroup affiliation, independent of other demographic or treatment variables. However, both EPN_PFA and EPN_PFB still benefit from increased extent of resection, with the survival rates being particularly poor for subtotally resected EPN_PFA, even with adjuvant radiation therapy. Patients with EPN_PFB who undergo gross total resection are at lower risk for relapse and should be considered for inclusion in a randomized clinical trial of observation alone with radiation reserved for those who experience recurrence. © 2016 by American Society of Clinical Oncology.

    "Facing the block" is defined as trimming tissue on a microtome from peripheral or deep surgical margins before sectioning. Facing includes trimming performed intentionally but unnecessarily, accidentally, or out of necessity because of one's choice of embedding and freezing method. To assess whether facing the block is associated with a greater number of stages to clear tumor and, by inference, a significant false positive rate. A retrospective analysis was performed comparing the average number of stages per Mohs case at two surgical facilities with the same physician over a 1-year period. Site A histotechnologists intentionally face the block, whereas site B histotechnologists do not. Tissue thickness lost during trimming at each site was recorded for 4 weeks. Comparing Sites A and B, stages per case were 1.92 and 1.53, respectively (p < .01) and trimming depths before the first section were 325 and 187 μm (p < .01). Facing the block is associated with 0.39 more stages per case and, by inference, a false-positive rate of approximately 39%. Mohs surgeons should evaluate the methods of tissue preparation that their histotechnologists use. Facing the block should not be performed. © 2013 by the American Society for Dermatologic Surgery, Inc. Published by Wiley Periodicals, Inc.

    Surgical site infection (SSI) and wound dehiscence are dreaded complications following laparotomy in general surgical patients, and can potentially occur more often in various comorbid states. Negative-pressure wound therapy (NPWT) has a positive effect of on open and complicated wounds and so has been used for at-risk surgical incisions with the aim of redistributing lateral tension and holding incision edges together. The aim of the present study was to compare the rate of wound complications following laparotomy in high-risk general surgical patients with a clean incision treated with closed-incision negative-pressure therapy (ciNPT) with those receiving conventional care. A retrospective review was performed of the hospital medical records of patients who underwent laparotomy between 1 October 2010 and 31 March 2012. Records of 69 patients who received ciNPT and 112 who were managed by adherent gauze dressings were included in the final analysis. Two (2.9%) patients in the ciNPT group and 23 (20.5%) in the non-NPWT group developed a wound complication following laparotomy (P surgery patients considered to have risk of developing wound complications following laparotomy. © 2016 The Authors.

    Spinal immobilization has been indicated for all blunt trauma patients suspected of having cervical spine injury. However, for traumatic cardiac arrest (TCA) patients, rapid transportation without compromising potentially reversible causes is necessary. Our objective was to investigate the temporal trend of spinal immobilization for TCA patients and to examine the association between spinal immobilization and survival. We conducted a retrospective cohort study using the Japan Trauma Data Bank 2004-2015 registry data. Our study population consisted of adult blunt TCA patients encountered at the scene of a trauma. The primary outcome was the survival proportion at hospital discharge, and the secondary outcome was the proportion achieving return of spontaneous circulation (ROSC). We examined the association between spinal immobilization and these outcomes using a logistic regression model based on imputed data sets with the multiple imputation method to account for missing data. Among 4313 patients who met the inclusion criteria, 3307 (76.7%) were immobilized. The proportion of patients that underwent spinal immobilization gradually decreased from 82.7% in 2004-2006 to 74.0% in 2013-2015. 1.0% of immobilized and 0.9% of non-immobilized patients had severe cervical spine injury. Spinal immobilization was significantly associated with lower survival at discharge (odds ratio [OR], 0.64; 95% confidence interval [CI], 0.42 to 0.98) and ROSC by admission (OR, 0.48; 95%CI, 0.27 to 0.87). There was no significant sub-group difference of the association between spinal immobilization and survival at discharge by patients with or without cervical spine injury (p for interaction 0.73). Spinal immobilization is widely used even for blunt TCA patients, even though it is associated with a lower rate of survival at discharge and ROSC by admission. According to these results, we suggest that spinal immobilization should not be routinely recommended for all blunt TCA patients

  2. The impact of Down syndrome screening on Taiwanese Down syndrome births: a nationwide retrospective study and a screening result from a single medical centre.

    Full Text Available A retrospective analysis of the Taiwanese National Birth Defect Registration and Notification System was conducted in order to determine the live birth- and stillbirth rates in infants with Down syndrome, trisomy 18, trisomy 13 and Turner syndrome between 2001 and 2010. The objective was to investigate the impact of Down syndrome screening on the Taiwanese Down syndrome live birth rate. In addition, the results of first-trimester Down syndrome screening between 2006 and 2011, and of second-trimester quadruple testing between 2008 and 2011, were obtained from the National Taiwan University Hospital. All Taiwanese infants born between 2001 and 2010 were included in the first part of the analysis, and women receiving first-trimester Down syndrome screening or second-trimester quadruple testing from the National Taiwan University Hospital were included in the second part. The live birth rate of infants with Down syndrome, per 100 000 live births, decreased from 22.28 in 2001 to 7.79 in 2010. The ratio of liveborn DS to total DS was 48.74% in 2001, and then decreased to 25.88% in 2006, when first-trimester screening was widely introduced in Taiwan. This ratio dropped to 20.64% in 2008, when the second-trimester quadruple test was implemented. The overall positive rate in first-trimester screening in the National Taiwan University Hospital was 3.1%, with a Down syndrome detection rate of 100%; the quadruple test had values of 9.0% and 75%, respectively. The use of first-trimester screening and the second-trimester quadruple test may be responsible for the marked decrease in the Taiwanese Down syndrome live birth rate observed between 2001 and 2010.

  3. Prime incision: A minimally invasive approach to breast cancer surgical treatment-A 2 cohort retrospective comparison with conventional breast conserving surgery.

    Directory of Open Access Journals (Sweden)

    Silvio Eduardo Bromberg

    Full Text Available The prime incision technique is an oncoplastic surgery aimed to remove both the breast tumor and the sentinel lymph node through one incision, thus providing better aesthetic results than the conventional breast conservative two incision technique. We retrospectively evaluated 2 cohorts of 60 consecutive breast cancer patients operated by either conventional breast conservative surgery (N = 26 or one incision surgery (N = 34. There were no recurrence or death events observed in any group. No difference was seen regarding the incidence of surgical complications. In the prime incision group the breast volume removed was significantly lower than in the conventional surgery group as well as was the surgical time and the number of dissected lymph nodes. Aesthetical results were better in the one incision group. Further prospective studies are needed to validate the one incision technique as a surgical option for selected early stage breast cancer patients.

    Hemolytic-uremic syndrome (HUS) is a clinical triad of microangiopathic hemolytic anemia, impaired renal function and thrombocytopenia, primarily affecting pre-school-aged children. HUS can be classified into diarrhea-associated HUS (D(+)HUS), usually caused by Shiga toxin-producing Escherichia coli (STEC), and non-diarrhea-associated HUS (D(-)HUS), both with potentially serious acute and long-term complications. Few data exists on the clinical features and long-term outcome of HUS in Norway. The aim of this paper was to describe these aspects of HUS in children over a 10-year period. We retrospectively collected data on clinical features, therapeutic interventions and long-term aspects directly from medical records of all identified HUS cases dialysis, with hemodialysis used most often in both groups, and plasma infusion(s) were utilized in 6/38 and 4/9 patients, respectively. Of extra-renal complications, neurological complications occurred in 9/38 and 2/9, serious gastrointestinal complications in 6/38 and 1/9, respiratory complications in 10/38 and 2/9, and sepsis in 11/38 and 3/9 cases, respectively. Cardiac complications were seen in two D(+)HUS cases. In patients where data on follow up ≥1 year after admittance were available, 8/21 and 4/7 had persistent proteinuria and 5/19 and 4/5 had persistent hypertension in the D(+)HUS and D(-)HUS group, respectively. Two D(+)HUS and one D(-)HUS patient were diagnosed with chronic kidney disease and one D(+)HUS patient required a renal transplantation. Two D(+)HUS patients died in the acute phase (death rate; 5 %). The HUS cases had a high rate of complications and sequelae, including renal, CNS-related, cardiac, respiratory, serious gastrointestinal complications and sepsis, consistent with other studies. This underlines the importance of attention to extra-renal manifestations in the acute phase and in renal long-term follow-up of HUS patients.

    High-risk medication exposure in the elderly is common and associated with increased mortality, hospitalizations, and emergency department (ED) visits. Skeletal muscle relaxants and antihistamines are high-risk medications commonly prescribed in elderly patients. The objective of this study was to determine the association between skeletal muscle relaxants or antihistamines and mortality, hospitalizations, and emergency department visits. This study used a new-user, retrospective cohort design using national Veteran Affairs (VA) data from 128 hospitals. Veterans ≥65 years of age on October 1, 2005 who received VA inpatient/outpatient care at least once in each of fiscal year (FY) 2005 and FY 2006 were included. Exposure to skeletal muscle relaxants and antihistamines was defined by the National Committee for Quality Assurance Healthcare Effectiveness Data and Information Set measures for high-risk medications in the elderly. Primary outcomes identified within one year of exposure were death, ED visit, or hospitalization; ED visits or hospitalizations due to falls and fracture were also assessed. Propensity score matching (1 to 1 match) was used to balance covariates between exposed patients and non-exposed patients. In this cohort of 1,807,404 patients 55,566 patients were included in the propensity-matched cohort for skeletal muscle relaxants and 60,058 patients were included in the propensity-matched cohort for anti-histamines. Mortality was lower in skeletal muscle relaxants-exposed patients (adjusted odds ratio [AOR] 0.87, 95% CI 0.81-0.94), but risk of emergency care (AOR 2.25, 95% CI 2.16-2.33) and hospitalization (AOR 1.56, 95% CI 1.48-1.65) was higher for patients prescribed skeletal muscle relaxants. Similar findings were observed for emergency and hospital care for falls or fractures. Mortality (AOR 1.93, 95% CI 1.82-2.04), ED visits (AOR 2.35, 95% CI 2.27-2.43), and hospitalizations (AOR 2.21, 95% CI 2.11-2.32) were higher in the antihistamine

    Many patients with gastric cancer seek traditional medicine consultations in Asian countries. This study aimed to investigate the prescription of Chinese herbal medicine (CHM) and its benefits for the patients with gastric cancer in Taiwan. From the Registry for Catastrophic Illness Patients Database, we included all patients with gastric cancer whose age at diagnosis was ≥18 from 1997 to 2010 in Taiwan. We used 1:1 frequency matching by age, sex, Charlson comorbidity score, treatment and index year to compare the CHM users and non-CHM users. We used the Cox regression model to compare the hazard ratios (HR) for the risk of mortality and the Kaplan-Meier curve for the survival time. There was a total of 1333 patients in the CHM-cohort and 44786 patients in the non-CHM cohort. After matching, we compared 962 newly diagnosed CHM users and 962 non-CHM users. Adjusted HRs (aHR) were higher among patients of above 60-year-old group, with a Charlson Comorbidity Index score ≥2 before the index date, and those who need surgery combined with chemotherapy or radiotherapy. CHM users had a lower HR of mortality risk (adjusted HR: 0.55, 95% CI: 0.48-0.62). Compared to the non-CHM users, the aHR among CHM-users is 0.37 (95% CI:0.2-0.67) for those who used CHM more than 180 days annually. The Kaplan-Meier curve revealed that the survival probability was higher for complementary CHM-users. Bai-Hua-She-She-Cao (Herba Hedyotidis Diffusae) was the most commonly used single herb and Xiang-Sha-Liu-Jun-Zi-Tang was the most commonly used herbal formula among CHM prescriptions. Complementary CHM improves the overall survival among patients with gastric cancer in Taiwan. Further ethnopharmacological investigations and clinical trials are required to validate the efficacy and safety. Copyright © 2017 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available Introduction: Phyllodes tumor (PT is a rare tumor of the breast. Usually, difficulty in making preoperative diagnoses and unpredictable clinical outcome of this disease leads to inappropriate management. Till date, no definite conclusion regarding the appropriate surgical procedure can be drawn. Objectives: The objective of this retrospective study is to study the clinicopathological correlation of phyllodes tumors in North-Central part of the India and also to evaluate efficacy of the various surgical options available for the management of phyllodes tumors of the breast. Materials and Methods: A retrospective study of 24 cases from the archives of department of surgery of three tertiary institutes of North-Central part of India. We reviewed the clinical, pathological features of this disease entity with a view to highlight relevant features. We also analyzed various surgical options done for primary as well as recurrent PT. Results: The breast masses in our study were particularly large. The mean size of the lump was 9.5΁5.5 cm (range was 4.0-23 cm. Histopathological report was benign, borderline, and malignant PT in 62.4%, 20.8%, and 16.8% of the cases, respectively. Overall, 31 surgical procedures (24 in primary and 7 in recurrent were performed. Simple lumpectomy, wide local excision and simple mastectomy were done in 25%, 27.4% and 27.4% of primary (non-recurrent cases of PT, respectively. Modified radical mastectomy and simple mastectomy with LD flap reconstruction was done in 7.2% and 2.4% in primary cases, respectively in recurrent cases, simple mastectomy was done in four cases and modified radical mastectomy was done in one case. Overall, recurrence was seen in 29.2% of the cases. The median time for recurrence was 6 months (range 5.0-36 months. 90% (6/7 of recurrence occurred in lumpectomy patients. Conclusion: The unpredictable behavior of histological types and the disputable results of particular surgical procedures have

    The immature coagulation system during infancy has age-related physiological differences in proteins that contribute to significant variation in heparin responsiveness through alterations in heparin-enhanced thrombin inhibition. The primary aim of this study was to evaluate the relationship between preoperative antithrombin (AT) activity and heparin responsiveness in neonates and infants undergoing congenital cardiac surgery. In this retrospective cohort study, neonates (aged 0-28 days) and infants (aged 29-365 days) undergoing congenital cardiac surgery in the 12-month period from October 2013 to 2014 were studied. The two age groups were compared for the primary endpoint of heparin response measured by the heparin sensitivity index (HSI), with heparin loading doses and heparin resistance being secondary endpoints. Multivariable linear regression analyses were used to explore the relationship between AT activity and heparin response measured by HSI. There were 122 infants and 19 neonates included in the study. After adjusting for low-molecular-weight heparin, unfractionated heparin, and platelet count, there was a significant relationship between AT activity and HSI (r = 0.44; P = 0.009). The median [interquartile range] HSI did not differ between neonates and infants (0.76 [0.69- 0.98] vs 0.89 [0.70-1.10] sec·unit(-1)·kg(-1), respectively; median difference, 0.08; 95% confidence interval [CI], -0.01 to 0.17; P = 0.182), despite the mean (standard deviation) AT activity differing between age groups [60 (16)% vs 84 (18)%, respectively; mean difference, 24; 95% CI, 15 to 32; P < 0.001]. There was a moderate relationship between AT activity and heparin response measured by HSI. Comparing neonates and infants, there was similar heparin responsiveness measured by HSI despite differing AT activity levels. These findings should help guide the perioperative administration of exogenous AT to neonates and infants and suggest that, outside the neonatal period, preoperative

    Spondylodiscitis may arise primarily via hematogenous spread or direct inoculation of virulent organisms during spine surgery. To date, no comparative data investigating the differences between primary and postoperative spondylodiscitis is available. Thus, the purpose of this retrospective study was to investigate differences between these two etiologies. One hundred fifty-nine patients that were treated at our department were included in the retrospective analysis. The patients were categorized into two groups based on the etiology of spondylodiscitis: group NS, primary spondylodiscitis without prior spinal surgery; group S, spondylodiscitis following spinal surgery. Evaluation included magnetic resonance imaging (MRI), laboratory values, clinical outcome, and operative or conservative management. Preoperative MRI showed higher rates of epidural and paraspinal abscess in patients with primary spondylodiscitis (p < 0.005). Vertebral bone destruction was more severe in group NS (p < 0.05). Survival rate in group S (98.2%) was higher than in group NS (87.5%, p = 0.024). The extent of the operative procedure in patients who were surgically treated (n = 116) differed between the two groups (p < 0.005). In conclusion, spondylodiscitis is a life-threatening and serious disease and requires long-term treatment. Primary spondylodiscitis is frequently associated with epidural and paraspinal abscess, vertebral bone destruction and has a higher mortality rate than postoperative spondylodiscitis. Therefore, primary spondylodiscitis shows a more severe course than spondylodiscitis following spine surgery.

    A retrospective study of data abstracted from the Diagnosis Procedure Combination (DPC) database, a national representative database in Japan. The aim of this study was to examine seasonal variations in the risk of reoperation for surgical site infection (SSI) following spinal fusion surgery. Although higher rates of infection in the summer than in other seasons were thought to be caused by increasing inexperience of new staff, high temperature, and high humidity, no studies have examined seasonal variations in the risk of SSI following spinal fusion surgery in the country where medical staff rotation timing is not in summer season. In Japan, medical staff rotation starts in April. We retrospectively extracted the data of patients who were admitted between July 2010 and March 2013 from the DPC database. Patients were included if they were aged 20 years or older and underwent elective spinal fusion surgery. The primary outcome was reoperation for SSI during hospitalization. We performed multivariate analysis to clarify the risk factors of primary outcome with adjustment for patient background characteristics. We identified 47,252 eligible patients (23,659 male, 23,593 female). The mean age of the patients was 65.4 years (range, 20-101 yrs). Overall, reoperation for SSI occurred in 0.93% of the patients during hospitalization. The risk of reoperation for SSI was significantly higher in April (vs. February; odds ratio, 1.93; 95% confidence interval, 1.09-3.43, P = 0.03) as well as other known risk factors. In subgroup analysis with stratification for type of hospital, month of surgery was identified as an independent risk factor of reoperation for SSI among cases in an academic hospital, although there was no seasonal variation among those in a nonacademic hospital. This study showed that month of surgery is a risk factor of reoperation for SSI following elective spinal fusion surgery, nevertheless, in the country where medical staff rotation timing is not in

    The aim of this study was to review the treatment outcomes of surgery and definitive chemoradiotherapy (CRT) in elderly patients with squamous cell carcinoma of the thoracic esophagus. A total of 64 patients aged 75 or older were retrospectively reviewed; 40 were treated with surgery and 24 with CRT. The CRT group included eight patients with unresectable disease and four patients medically unfit for surgery. Surgery included esophagectomy with lymphadenectomy and CRT consisted of 60-70 Gy of radiation concurrent with 5-fluorouracil alone or combined with cisplatin. Short- and long-term outcomes and survival of each modality were assessed. In the surgery group, 33 patients (82.5%) had co-morbid conditions. Complete resection rate was 90.0%. An overall post-operative complication rate was 65.0% and in-hospital mortality was seen in three patients (7.5%). In the CRT group, complete response rate was 41.7%. Leukopenia was most common Grade 3 hematological toxicity. Treatment-related deaths caused by acute toxicities occurred in three patients (12.5%), whereas those caused by late toxicities in four (16.7%). For cStage I disease in the surgery group, the overall 1-, 3- and 5-year survival rate were 90.9%, 63.6% and 54.5%, respectively, with a median survival time of 78.7 months. For cStages II-IV, the median survival time of the surgery and the CRT group was 18.7 and 12.8 months, respectively. The short- and long-term outcomes of surgery for the elderly seemed acceptable; however, definitive CRT may be a promising treatment modality. Further investigation may alter the sphere of influence in the field of esophageal cancer treatment in the elderly. (author)

    To investigate the survival and prognostic factors of stage 0 to III rectal cancer in 10 years. Clinical data and follow-up of 856 rectal cancer patients with stage 0-III underwent curative surgery from January 2000 to December 2010 were retrospective analyzed. There were 470 male and 386 female patients, with a mean age of (58 ± 12) years. Kaplan-Meier method was used to analyze the overall survival and disease free survival. Log-rank test was used to compare the survival between groups. Cox regression was used to analyze the independent prognostic factors of rectal cancer. The patients in each stage were stage 0 with 18 cases, stage I with 209 cases, stage II with 235 cases, and stage III with 394 cases. All patients received curative surgery. There were 296 patients evaluated as cT3, cT4 and any T with N+ received preoperative radiotherapy. 5.4% patients got pathological complete response (16/296), and the recurrence rate was 4.7% (14/296). After a median time of 41.7 months (range 4.1 to 144.0 months) follow-up, the 5-year overall survival rate in stage 0 to I of was 91.0%, stage II 86.2%, and stage III 60.0%, with a significant difference (P=0.000). The cumulative local recurrence rate was 4.8% (41/856), of which 70.7% (29/41) occurred within 3 years postoperatively, 97.6% (40/41) in 5 years. The cumulative distant metastasis rate was 16.4% (140/856), of which 82.9% (129/140) occurred within 3 years postoperatively, 96.4% (135/140) in 5 years. The incidence of abnormal imaging findings was significantly higher in pulmonary than liver and other sites metastases (75.0% vs. 21.7%, χ² =25.691, P=0.000). The incidence of CEA elevation was significantly higher in liver than lung and other sites metastases (56.8% vs. 37.8%, χ² =25.691, P=0.000). Multivariable analysis showed that age (P=0.015, HR=1.385, 95% CI: 1.066 to 1.801), surgical approach (P=0.029, HR=1.337, 95% CI: 1.030 to 1.733), differentiation (P=0.000, HR=1.535, 95% CI: 1.222 to 1.928), TNM stage (P

    The objective of this study was to collect integrated data from nationwide hospitals using a web-based national database system to build up our own risk model for the outcome from thoracic aortic surgery. The Japan Adult Cardiovascular Surgery Database was used; this involved approximately 180 hospitals throughout Japan through a web-based data entry system. Variables and definitions are almost identical to the STS National Database. After data cleanup, 4707 records were analyzed from 97 hospitals (between January 1, 2000, and December 31, 2005). Mean age was 66.5 years. Preoperatively, the incidence of chronic lung disease was 11%, renal failure was 9%, and rupture or malperfusion was 10%. The incidence of the location along the aorta requiring replacement surgery (including overlapping areas) was: aortic root, 10%; ascending aorta, 47%; aortic arch, 44%; distal arch, 21%; descending aorta, 27%; and thoracoabdominal aorta, 8%. Raw 30-day and 30-day operative mortality rates were 6.7% and 8.6%, respectively. Postoperative incidence of permanent stroke was 6.1%, and renal failure requiring dialysis was 6.7%. OR for 30-day operative mortality was as follows: emergency or salvage, 3.7; creatinine >3.0 mg/dL, 3.0; and unexpected coronary artery bypass graft, 2.6. As a performance metric of the risk model, C-index of 30-day and 30-day operative mortality was 0.79 and 0.78, respectively. This is the first report of risk stratification on thoracic aortic surgery using a nationwide surgical database. Although condition of these patients undergoing thoracic aortic surgery was much more serious than other procedures, the result of this series was excellent.

    Surgery is a common and important component of breast cancer treatment. We assessed the rates of breast cancer surgery across Canada from 2007/08 to 2009/10. We used hospital and day surgery data from the Canadian Institute for Health Information to assemble a cohort of women who had undergone breast cancer surgery. We identified the index surgical procedure and subsequent surgical procedures performed within 1 year for each woman included in the analysis. We calculated the crude mastectomy rate for each province, and we calculated the adjusted mastectomy rate for select jurisdictions using a logistic regression model fitted using age, neighbourhood income quintile and travel time. In total, 57 840 women underwent breast cancer surgery during the study period. Among women with unilateral invasive breast cancer, the crude mastectomy rate was 39%. Adjusted rates for mastectomy varied widely by province (26%-69%). The rate of re-excision within 1 year for women who had breast-conserving surgery as their index procedure was 23% and varied by province in terms of frequency and type (mastectomy or repeat breast-conserving surgery). Among women who underwent mastectomy for unilateral invasive breast cancer, 6% also underwent contralateral prophylactic mastectomy, and 7% had immediate breast reconstruction following surgery. Of mastectomy procedures, 20% were performed as day surgery; for breast-conserving surgery, 70% were performed as day surgery. There is substantial interprovincial variation in surgical care for breast cancer in Canada. Further research is needed to better understand such variation, and continued monitoring should be the focus of quality initiatives.

    Background: Interleukin (IL)-1 inhibitors have been suggested as possible therapeutic options in a large number of old and new clinical entities characterized by an IL-1 driven pathogenesis. Objectives: To perform a nationwide snapshot of the on-label and off-label use of anakinra (ANA) and canakinumab (CAN) for different conditions both in children and adults. Methods: We retrospectively collected demographic, clinical, and therapeutic data from both adult and pediatric patients treated with IL-1 inhibitors from January 2008 to July 2016. Results: Five hundred and twenty-six treatment courses given to 475 patients (195 males, 280 females; 111 children and 364 adults) were evaluated. ANA was administered in 421 (80.04%) courses, CAN in 105 (19.96%). Sixty-two (32.1%) patients had been treated with both agents. IL-1 inhibitors were employed in 38 different indications (37 with ANA, 16 with CAN). Off-label use was more frequent for ANA than CAN (p < 0.0001). ANA was employed as first-line biologic approach in 323 (76.7%) cases, while CAN in 37 cases (35.2%). IL-1 inhibitors were associated with corticosteroids in 285 (54.18%) courses and disease modifying anti-rheumatic drugs (DMARDs) in 156 (29.65%). ANA dosage ranged from 30 to 200 mg/day (or 1.0–2.0 mg/kg/day) among adults and 2–4 mg/kg/day among children; regarding CAN, the most frequently used posologies were 150mg every 8 weeks, 150mg every 4 weeks and 150mg every 6 weeks. The frequency of failure was higher among patients treated with ANA at a dosage of 100 mg/day than those treated with 2 mg/kg/day (p = 0.03). Seventy-six patients (14.4%) reported an adverse event (AE) and 10 (1.9%) a severe AE. AEs occurred more frequently after the age of 65 compared to both children and patients aged between 16 and 65 (p = 0.003 and p = 0.03, respectively). Conclusions: IL-1 inhibitors are mostly used off-label, especially ANA, during adulthood. The high frequency of good clinical responses suggests that IL-1

    Persisting pain after spine surgery remains a challenge for the patient and the pain physician. The etiology depends on age, pathology and the interval between the first and the revision surgery. In young patients who underwent initially to discectomy, the etiology of failed back surgery syndrome (FBSS) is commonly a recurrence of herniation whereas in the elderly population, who has previously undergone a spinal fusion, persisting pain might be due to secondary sagittal unbalance associated, as a consequence, to adjacent disc disease or pseudarthrosis. To review the etiology of failed back surgery syndrome and to discuss the radiological work-up and the treatment strategies. Retrospective analysis of 39 consecutive patients diagnosed with FBSS. For all cases, the following parameters were reviewed: original diagnosis and initial surgery, interval between the last surgery and the revision procedure, final diagnosis after revision. Treatment options were discussed. Twelve patients have undergone decompressive procedures and 27 had one or multilevel fusion for various back and/or leg pain. In group 1 (decompressive surgery), the mean age of patients who had a disc herniation was 42.2 years and 69 years for patients who had laminectomies for lumbar stenosis. In group 2 (fusion), the mean age was 63.3. Loss of lumbar lordosis in elderly after one or several laminectomy(ies) was found to be a cause of failure because of sagittal kyphosis and consecutive back pain. In the fused group, suboptimal correction of lumbar lordosis could generate a pseudarthrosis, proximal junctional kyphosis and persisting pain. Dealing with FBSS patients is far from simple but it corresponds to daily practice for spine surgeons. Clinical and radiological assessments should include a full diagnostic work-up focusing on sagittal balance. Surgical treatment and re-operation might be an option if a consistent source of pain is detected. Copyright © 2015. Published by Elsevier Masson SAS.

    Background. There are a few papers that compared the lateral transversus abdominis plane (TAP) block with the posterior TAP block. Our study aimed to compare retrospectively the quality of analgesia after laparoscopic gynecologic surgery using the lateral TAP block with general anesthesia versus the posterior TAP block with general anesthesia. Method. Sixty-seven adult female patients were included in this retrospective study. Of these patients, thirty-four patients received the lateral TAP block with general anesthesia (lat. TAP group), and the rest of thirty-three patients received the posterior TAP block with general anesthesia (pos. TAP group). Pain scores both at rest and at movement and the use of additional analgesic drugs were recorded in the postoperative care unit within twenty-four hours after the operation. Postoperative complications were noted. Results. Patients who received pos. TAP reported lower visual analog scale (VAS) pain scores in all points, within twenty-four hours after the operation, than patients who received lat. TAP. Moreover, with the use of additional analgesic drugs, the incidence of nausea and vomiting during the first twenty-four hours after surgery was lower in the pos. TAP group than in the lat. TAP group. Conclusion. The posterior TAP block provided more effective analgesia than the lateral TAP block in patients undergoing laparoscopic gynecologic surgery.

    The prevention of medullary thyroid cancer in patients with multiple endocrine neoplasia type 2 syndrome has demonstrated the ability of molecular diagnosis and prophylactic surgery to improve patient outcomes. However, the other major neoplasia associated with multiple endocrine neoplasia type 2, phaeochromocytoma, is not as well characterised in terms of occurrence and treatment outcomes. In this study, we aimed to systematically characterise the outcomes of management of phaeochromocytoma associated with multiple endocrine neoplasia type 2. This multinational observational retrospective population-based study compiled data on patients with multiple endocrine neoplasia type 2 from 30 academic medical centres across Europe, the Americas, and Asia. Patients were included if they were carriers of germline pathogenic mutations of the RET gene, or were first-degree relatives with histologically proven medullary thyroid cancer and phaeochromocytoma. We gathered clinical information about patients'RET genotype, type of treatment for phaeochromocytoma (ie, unilateral or bilateral operations as adrenalectomy or adrenal-sparing surgery, and as open or endoscopic operations), and postoperative outcomes (adrenal function, malignancy, and death). The type of surgery was decided by each investigator and the timing of surgery was patient driven. The primary aim of our analysis was to compare disease-free survival after either adrenal-sparing surgery or adrenalectomy. 1210 patients with multiple endocrine neoplasia type 2 were included in our database, 563 of whom had phaeochromocytoma. Treatment was adrenalectomy in 438 (79%) of 552 operated patients, and adrenal-sparing surgery in 114 (21%). Phaeochromocytoma recurrence occurred in four (3%) of 153 of the operated glands after adrenal-sparing surgery after 6-13 years, compared with 11 (2%) of 717 glands operated by adrenalectomy (p=0.57). Postoperative adrenal insufficiency or steroid dependency developed in 292 (86%) of 339

    Topping-off surgery is a newly-developed surgical technique which combines rigid fusion with an interspinous process device in the adjacent segment to prevent adjacent segment degeneration. There are few reports on Topping-off surgery and its rationality and indications remains highly controversial. Our study aims to investigate the short-term and mid-term clinical results of Topping-off surgery in preventing adjacent segment degeneration when mild or moderate adjacent segment degeneration existed before surgery. The 25 cases that underwent L5-S1 posterior lumbar interbody fusion (PLIF) + L4-L5 interspinous process surgeries between April 2008 and March 2010 formed Topping-off group. The 42 cases undergoing L5-S1 PLIF surgery formed PLIF group. Both groups matched in gender, age, body mass index and Pfirrmann grading (4 to 6). The patients were evaluated with visual analogue scale (VAS) and Japanese orthopaedic association (JOA) scores before surgery and in the last follow-up. Modic changes of endplates were recorded. The follow-up averaged 24.8 and 23.7 months. No symptomatic or radiological adjacent segment degeneration was observed. There was no significant difference in intraoperative blood loss or postoperative drainage. VAS and lumbar JOA scores improved significantly in both groups (t = 12.1 and 13.5, P adjacent segment degeneration, restrict the adjacent segment's ROM in extension and prevent excessive olisthesis of adjacent segment in both extension and flexion.

    Introduction: The incidence of maxillofacial injuries is on the rise due to motor vehicle accidents and increased incidence of violence in recent times. The aim of this retrospective study was to determine the incidence, etiology, and the pattern of fractures in the maxillofacial region. Materials and Methods: After obtaining permission from the concerned authorities, a predesigned questionnaire was used to collect the necessary data from the department. A retrospective analysis of 787 patients, who suffered trauma and were managed in the Department of Oral and Maxillofacial Surgery, Indira Gandhi Government Dental College (IGGDC), Jammu over a period of 2 years was carried out. Results: Road traffic accident (RTA) was the common cause of maxillofacial injuries. Men sustained more injuries as compared to women. Injuries were most commonly sustained in the age group of 11-40 years, constituting about 76% of all injuries, mandibular fractures were the most common. Conclusion: RTAs were the commonest cause for the maxillofacial injuries. PMID:25937724

    Pyogenic spondylodiscitis is a form of spinal infection that can result in severe back pain and even death. However, information is lacking on the relative effectiveness of various therapies. A retrospective chart review was conducted to investigate whether early surgical treatment of pyogenic spondylodiscitis coupled with intravenous antibiotics results in better patient prognoses than intravenous antibiotics therapy alone. All patients treated for pyogenic spondylodiscitis at a single medical center from July 2006 to July 2011 were retrospectively reviewed. The inclusion criteria consisted of diagnosis of an early stage infection without neurological deficit, and patients without severe sepsis who were suitable candidates for early surgery as determined by a Pittsburgh bacteremia score spondylodiscitis typically achieves a better prognosis, shorter hospitalization period, and subsequent significant improvement in kyphotic deformity and quality of life.

    Orthopedic and trauma surgery is the specialty for which claims for compensation are most often filed. Little data exists on the subject in France, especially in a teaching hospital. We conducted a retrospective study aimed at (1) identifying the epidemiological characteristics of patients filing claims against the orthopedic surgery and traumatology department of a teaching hospital in France, (2) analyzing the surgical procedures involved, the type of legal proceedings, and the financial consequences. The epidemiological profile of proceedings seeking damages in France is consistent with the data from European and American studies. An observational, retrospective, single-center study of all claims for damages between 2007 and 2016 involving the orthopedic and trauma surgery department of a teaching hospital was carried out. Patients' epidemiological data, the surgical procedure, type of legal proceeding, and financial consequences were analyzed. Of the 51,582 surgical procedures performed, 71 claims (0.0014%) were analyzed (i.e., 1/726 procedures). A significant increase in the number of cases (p=0.040) was found over a 10-year period. Of these, 36/71 (53.7%) were submitted to the French regional conciliation and compensation commission (CRCI), 23/71 (32.8%) were filed with the administrative court, and 12/71 (13.4%) were submitted for an amicable settlement. The most common reason for which patients filed claims was hospital-acquired infections, with 36/71 (50.7%) cases. Twenty-nine complaints (40.8%) resulted in monetary damages being awarded to the patient, with an average award of € 28,301 (€ 2,400-299,508). Damage awards were significantly higher (pClaims against orthopedic surgeons have been increasing significantly over the last 10 years. Although rare, they represent a significant cost to society. Hospital-acquired infections are the main reason for disputes in our specialization. IV, retrospective study. Copyright © 2017 Elsevier Masson SAS. All

    Although laparoscopy is rapidly becoming the abdominal surgical modality of choice in adults, there are obstacles to its use in children. We analyzed our experience with pediatric laparoscopic surgery over the past 5 years, with particular emphasis on emergency procedures. We retrospectively evaluated the records of patients aged time, total length of hospital stay, and postoperative complications.During the 5-year study period, 482 laparoscopic procedures were performed on patients aged times and shorter postoperative hospital stays. The numbers of laparoscopic procedures performed increased over time. Pediatric laparoscopic surgery for emergency conditions provides excellent results, including better exposure and cosmetic outcomes than laparotomy. At our institution, the numbers and types of laparoscopic procedures performed have increased over time, and the outcomes of laparoscopic procedures have improved.

    Retrospective analysis using national administrative data. This study presents US nationwide trends in the surgical management of patients with lumbar spinal stenosis (LSS) with and without coexisting spondylolisthesis and scoliosis from 2004 to 2009. Lack of consensus and wide variability exists in surgical decision making for patients with LSS. Data were obtained from the Nationwide Inpatient Sample, a database developed as part of the Healthcare Cost and Utilization Project. All discharged patients with a primary diagnosis of LSS were identified. Three subgroups were studied: (1) LSS alone, (2) LSS with spondylolisthesis, and (3) LSS with scoliosis. Surgical treatment was divided into 3 groups: (1) decompression only (laminectomy, discectomy), (2) simple fusion (1-2 disc levels, single approach), and (3) complex fusion (>2 disc levels or a combined posterior and anterior approach). Between 2004 and 2009, national estimates for the annual number of discharged inpatients with a primary diagnosis of LSS increased from 94,011 (population rate, [the age adjusted population rate per 100,000] 32.1) to 102,107 (population rate, 33.3). The rate of decompressions decreased from 58.5% to 49.2% for discharged patients with LSS from 2004 to 2009 (P spondylolisthesis and 67.6% of patients with coexisting scoliosis underwent a fusion procedure. This study demonstrates that the rate of simple fusion surgery has increased for treatment of LSS compared with decompression only. 4.

    The main goal of this study was to determine the effects of incretins on type 2 diabetes (T2D) remission after Roux-en-Y gastric bypass (RYGB) surgery for patients taking insulin. Type 2 diabetes is a chronic disease with potentially debilitating consequences. RYGB surgery is one of the few interventions that can remit T2D. Preoperative use of insulin, however, predisposes to significantly lower T2D remission rates. A retrospective cohort of 690 T2D patients with at least 12 months follow-up and available electronic medical records was used to identify 37 T2D patients who were actively using a Glucagon-like peptide 1 (GLP-1) agonist in addition to another antidiabetic medication, during the preoperative period. Here, we report that use of insulin, along with other antidiabetic medications, significantly diminished overall T2D remission rates 14 months after RYGB surgery (9%) compared with patients not taking insulin (56%). Addition of the GLP-1 agonist, however, increased significantly T2D early remission rates (22%), compared with patients not taking the GLP-1 agonist (4%). Moreover, the 6-year remission rates were also significantly higher for the former group of patients. The GLP-1 agonist did not improve the remission rates of diabetic patients not taking insulin as part of their pharmacotherapy. Preoperative use of antidiabetic medication, coupled with an incretin agonist, could significantly improve the odds of T2D remission after RYGB surgery in patients also using insulin.

    Postoperative pulmonary complications (PPCs) are common and result in prolonged hospital stays, higher costs and increased mortality. However, data on the incidence and predictors of PPCs after major oral and maxillofacial surgery with microvascular reconstruction are rare. This retrospective analysis identifies perioperative risk factors for postoperative pulmonary complications (PPCs) after major oral and maxillofacial surgery with microvascular reconstruction. Perioperative data and patient records of 648 subjects were analyzed in the period of June 2007 to May 2013. PPCs were defined as pneumonia, atelectasis, pleural effusions, pulmonary embolism, pulmonary oedema, pneumothorax or respiratory failure. 18.8% of all patients developed PPCs. Patient-related risk factors for PPCs were male sex, advanced age, smoking, alcohol abuse, a body mass index >30, American Society of Anaesthesiologists grade higher than 2, pre-existent pulmonary diseases and preoperative antihypertensive medication. Among the investigated procedure-related variables, the length of the operation, the amount of fluid administration and blood transfusion and an impaired oxygenation index during surgery were shown to be associated with the development of PPCs. Using a multivariable logistic regression model, we identified a body mass index >30, American Society of Anaesthesiologists grade higher than 2 and alcohol abuse as independent risk factors for PPCs. Several perioperative factors can be identified that are associated with the development of PPCs. Patients having one or more of these conditions should be subjected to intensified postoperative pulmonary care. Copyright © 2016 European Association for Cranio-Maxillo-Facial Surgery.

    The aim of this study was to determine the effects of nanocarbon particles in combination with meticulous capsular dissection on enhancing the identification and protecting the function of parathyroid glands in thyroid cancer surgery.The data of 97 patients with papillary thyroid tumors diagnosed and treated at the Second Affiliated Hospital, Harbin Medical University between January 2014 and February 2015 were reviewed. Data regarding the sex, age, calcium and parathyroid hormone (PTH) levels, tumor size, multifocality, T stage, and extrathyroid invasion were collected. The incidence of surgeries in which the parathyroid glands were cut mistakenly, the concentration of serum calcium and parathyroid hormone before surgery (baseline) and after surgery on days 1, 3, and 7, and 1 and 6 months in the patients of the two groups (the nanocarbon and control groups) were analyzed.Fifty-two patients underwent meticulous capsular dissection combined with nanocarbon treatment (nanocarbon group), and 45 underwent meticulous capsular dissection alone (control group). The nanocarbon group showed a significantly higher total and average number of revealed parathyroid glands (average number is the mean for different individuals have different number) and a lower incidence of the parathyroid glands being mistakenly cut, in addition to a lower level of hypoparathyroidism than control group following surgery (P parathyroid in thyroid cancer surgery, reduce the risk of mistakenly cutting the parathyroid, and reduce the incidence of postoperative hypoparathyroidism.

    To determine the risk factors of morbidity after surgery for ileocolonic Crohn disease (CD). The risk factors of morbidity after surgery for CD, particularly the role of anti-TNF therapy, remain controversial and have not been evaluated in a large prospective cohort study. From 2013 to 2015, data on 592 consecutive patients who underwent surgery for CD in 19 French specialty centers were collected prospectively. Possible relationships between anti-TNF and postoperative overall morbidity were tested by univariate and multivariate analyses. Because treatment by anti-TNF is possibly dependent on the characteristics of the patients and disease, a propensity score was calculated and introduced in the analyses using adjustment of the inverse probability of treatment-weighted method. Postoperative mortality, overall and intra-abdominal septic morbidity rates in the entire cohort were 0%, 29.7%, and 8.4%, respectively; 143 (24.1%) patients had received anti-TNF risk factor of the overall postoperative morbidity (odds-ratio [OR] =1.99; confidence interval [CI] 95% = 1.17-3.39, P = 0.011), with preoperative hemoglobin 180 min (OR = 2.71; CI 95% = 1.54-4.78, P risk of overall (OR = 2.98; CI 95% = 2.04-4.35, P risk of morbidity after surgery for ileocolonic CD. This information should be considered in the surgical management of these patients, particularly with regard to the preoperative preparation and indication of temporary defunctioning stoma.

However, data on the incidence and risk factors of POP after oral and maxillofacial surgery are rare. This study aims to identify perioperative risk factors for POP after major oral cancer (OC surgery.Perioperative data and patient records of 331 consecutive subjects were analyzed in the period of April 2014 to March 2016. We individually traced each OC patient for a period to discharge from the hospital or 45 days after surgery, whichever occur later.The incidence of POP after major OC surgery with free flap construction or major OC surgery was 11.6% or 4.5%, respectively. Patient-related risk factors for POP were male sex, T stage, N stage, clinical stage and preoperative serum albumin level. Among the investigated procedure-related variables, incision grade, mandibulectomy, free flap reconstruction, tracheotomy, intraoperative blood loss, and the length of the operation were shown to be associated with the development of POP. Postoperative hospital stay was also significantly related to increased incidence of POP. Using a multivariable logistic regression model, we identified male sex, preoperative serum albumin level, operation time and postoperative hospital stay as independent risk factors for POP.Several perioperative risk factors can be identified that are associated with POP. At-risk oral cancer patients should be subjected to intensified postoperative pulmonary care.

    This study aimed to determine surgical outcomes related to hand-assisted robotic surgery (HARS) for staging of ovarian cancer and uterine cancers with high risk of peritoneal spread and compare them to laparotomy and standard robotic-assisted surgery. A retrospective cohort study of women undergoing staging for uterine and ovarian cancer between January 2011 and July 2013 at a major metropolitan teaching hospital was reviewed. Patients undergoing HARS were matched with patients undergoing staging laparotomy [exploratory laparotomy (XLAP)] for the same indications and with patients undergoing traditional robotic surgery (RS) for staging of endometrioid endometrial cancer. In HARS, a longer incision is used to allow palpation of the peritoneal surfaces, to exteriorize the small bowel, to examine the mesentery, and to perform omentectomy. One hundred five patients were analyzed (15 HARS, 45 RS, 45 XLAP). Compared with XLAP, HARS was associated with decreased blood loss (200 vs 400 mL, P = 0.011) and shorter hospital stay (1 vs 4 days, P < 0.001). Patients who had undergone HARS had fewer major complications, but those results did not reach statistical significance (0% vs 27%, P = 0.063). Hand-assisted robotic surgery was associated with higher blood loss and length of stay as compared to robotic staging of endometrioid endometrial cancer (RS). Minor wound complications were also more common (27% vs 2%, P = 0.012). Hand-assisted robotic surgery allows for thorough visual and tactile assessment of peritoneal surfaces. It represents a safe alternative to laparotomy for staging of ovarian and uterine cancers with high risk of peritoneal spread. Long-term follow-up study is needed to determine oncologic adequacy of HARS.

    Early stages of Crohn's disease [CD] are predominantly inflammatory and early treatment could be useful to change the natural history of CD. We aimed to evaluate the impact of early treatment in our cohort of CD patients. We retrospectively reviewed clinical records of all CD patients at our centre who have received immunomodulators. Time from diagnosis to first CD-related major abdominal surgery or end of follow-up was considered. Dates of diagnosis, of starting immunomodulators (thiopurines / anti-tumour necrosis factor [TNF]), and of the first CD-related surgery when appropriate were collected. Of 422 patients who received thiopurines, 189 operated patients started thiopurines after a median of 117 months (interquartile range [IQR] 44-196) since diagnosis; non-operated patients, after a median of 30 months [IQR 6-128], p risk of major abdominal surgery in Crohn's disease.

    A xenogeneic DNA vaccination has been licensed for use in dogs with locally controlled stage II and III oral malignant melanoma (OMM). At present, there are limited outcome data for dogs with OMM treated with surgery and immunotherapy. The aim of this study is to retrospectively review the outcome and survival of 32 dogs affected by OMM that were treated with a combination of surgery and the xenogeneic DNA vaccination (with the addition of radiotherapy in some cases) and to determine the influence of surgical margins and delay in receiving vaccination. The overall median survival time (MST) was 335 days (95% CI: 301-540 days), and the overall median progression-free survival (PFS) was 160 days (mean 182 days, 95% CI: 132-232 days). Stage, completeness of surgical margins and delay in administration of the vaccine did not appear to statistically influence survival or PFS, although these results may reflect the low statistical power of the study due to small numbers. Further studies are required to assess whether the addition of any adjuvant treatment to surgery, including immunotherapy, is able to significantly prolong survival in cases of canine oral melanoma.

    To assess the utility of nasotracheal tubes in postoperative oxygen supplementation in dogs following corrective surgery for brachycephalic syndrome. Retrospective study 2003-2007. University teaching hospital. Thirty-six client-owned dogs that underwent corrective surgery for brachycephalic syndrome. None. Medical records were reviewed for animals that underwent surgical interventions for brachycephalic syndrome including palatoplasty, ventriculectomy, and rhinoplasty. Data collected included signalment, presenting complaints, analgesic and surgical interventions, type of supplemental oxygen therapy, complications and mortality occurring during hospitalization. A nasotracheal tube (NTT) was placed in 20 dogs at the end of surgery; 16 dogs received other forms of oxygen supplementation (8) or no oxygen supplementation (8) during recovery. The total number of postoperative complications was similar in both groups (8/20 dogs with NTTs and 7/16 in those without NTTs). However, respiratory distress was observed in 5 dogs without NTTs but was not observed in any dog while an NTT was in place. One dog in each group died postoperatively. Placement of an NTT was found to be easy and may offer benefit in dogs with brachycephalic syndrome as a noninvasive means of delivering oxygen. The use of NTT may minimize severe postoperative morbidity, in particular by reducing postoperative respiratory distress. © Veterinary Emergency and Critical Care Society 2011.

    OBJECTIVE The aim of this study was to investigate the treatment outcomes and social engagement of patients who had undergone pediatric epilepsy surgery more than 10 years earlier. METHODS Between 1983 and 2005, 110 patients younger than 16 years underwent epilepsy surgery at the National Epilepsy Center, Shizuoka Institute of Epilepsy and Neurological Disorders. The authors sent a questionnaire to 103 patients who had undergone follow-up for more than 10 years after surgery; 85 patients (82.5%) responded. The survey contained 4 categories: seizure outcome, use of antiepileptic drugs, social participation, and general satisfaction with the surgical treatment (resection of the epileptic focus, including 4 hemispherectomies). The mean patient age at the time of surgery was 9.8 ± 4.2 (SD) years, and the mean duration of postoperative follow-up was 15.4 ± 5.0 years. Of the 85 patients, 79 (92.9%) presented with a lesional pathology, such as medial temporal sclerosis, developmental/neoplastic lesions, focal cortical dysplasia, and gliosis in a single lobe. RESULTS For 65 of the 85 responders (76.5%), the outcome was recorded as Engel Class I (including 15 [93.8%] of 16 patients with medial temporal sclerosis, 20 [80.0%] of 25 with developmental/neoplastic lesions, and 27 [73.0%] of 37 with focal cortical dysplasia). Of these, 29 (44.6%) were not taking antiepileptic drugs at the time of our survey, 29 (44.6%) held full-time jobs, and 33 of 59 patients (55.9%) eligible to drive had a driver's license. Among 73 patients who reported their degree of satisfaction, 58 (79.5%) were very satisfied with the treatment outcome. CONCLUSIONS The seizure outcome in patients who underwent resective surgery in childhood and underwent followup for more than 10 years was good. Of 85 respondents, 65 (76.5%) were classified in Engel Class I. The degree of social engagement was relatively high, and the satisfaction level with the treatment outcome was also high.

    Full Text Available Accurate predictions of functional outcome after limb salvage surgery (LSS in the lower limb are important for several reasons, including informing the patient preoperatively and, in some cases, deciding between amputation and LSS. This study aimed to elucidate the correlation between surgeon-predicted and patient-reported functional outcome of LSS in the Netherlands. Twenty-three patients (between six months and ten years after surgery and five independent orthopedic oncologists completed the Toronto Extremity Salvage Score (TESS and the RAND-36 physical functioning subscale (RAND-36 PFS. The orthopedic oncologists made their predictions based on case descriptions (including MRI scans that reflected the preoperative status. The correlation between patient-reported and surgeon-predicted functional outcome was “very poor” to “poor” on both scores (r2 values ranged from 0.014 to 0.354. Patient-reported functional outcome was generally underestimated, by 8.7% on the TESS and 8.3% on the RAND-36 PFS. The most difficult and least difficult tasks on the RAND-36 PFS were also the most difficult and least difficult to predict, respectively. Most questions had a “poor” intersurgeon agreement. It was difficult to accurately predict the patient-reported functional outcome of LSS. Surgeons’ ability to predict functional scores can be improved the most by focusing on accurately predicting more demanding tasks.

    To estimate the risk of surgery for subacromial impingement syndrome (SIS) in relation to occupational exposures, lifestyle factors and diabetes mellitus. We conducted a case-control study nested in a register-based cohort study of the Danish working population. For each of 3000 first-time cases of surgery for SIS, two age-matched and sex-matched controls were drawn. Cases and controls received a questionnaire on job history and other factors. Job histories were combined with a psychosocial job exposure matrix (JEM) and the updated Shoulder JEM, which provided exposure intensities on measurement scales. Ten-year cumulative exposures to upper arm elevation >90°, repetitive shoulder movements, forceful shoulder exertions and hand-arm vibrations (HAVs) were estimated. We used conditional logistic regression. There were 5396 persons (60%) who answered the questionnaire. For occupational mechanical exposures, the adjusted OR (OR adj ) ranged from 1.9 (95% CI 1.5 to 2.5 for HAVs) to 2.5 (95% CI 1.9 to 3.5 for force) among men and 1.7 (95% CI 1.2 to 2.5 for HAVs) to 2.0 (95% CI 1.3 to 2.9 for force) among women. No statistically significant associations were found for occupational psychosocial factors. Body mass index (BMI) and pack-years of smoking showed OR adj up to 2.0. Diabetes mellitus showed OR adj of 1.5 (95% CI 1.1 to 2.2) for men and 2.2 (95% CI 1.4 to 3.4) for women. Our findings add to the evidence of an increased risk of surgery for SIS in relation to occupational cumulative mechanical exposures, even when an increased risk in relation to BMI, smoking and diabetes mellitus is taken into account. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    BACKGROUND: Elevated levels of depressive symptoms are generally found among cancer patients, but results from existing studies vary considerably with respect to prevalence and proposed risk factors. PURPOSE: To study the prevalence of depressive symptoms and major depression 3-4 months following...... breast cancer during the 2 1/2 year study period. Of these, 3343 women (68%) participated in a questionnaire study 12-16 weeks following surgery. Depressive symptoms (Beck's Depression Inventory II) and health-related behaviors were assessed by questionnaire. The Danish Breast Cancer Cooperative Group...... symptoms and major depression (13.7%) compared to population-based samples. The pre-cancer variables: Social status, net-wealth, ethnicity, comorbidity, psychiatric history, and age were all independent risk factors for depressive symptoms. Of the clinical variables, only nodal status carried additional...

    This study was designed to assess the satisfaction or otherwise of a proportion of the U.K. population who have undergone standard four-port laparoscopic cholecystectomy within the past 18 months. The results should indicate whether there is potential demand for a new, improved approach to surgery. Patients who underwent laparoscopic cholecystectomy between October 2008 and October 2009 in two geographically separated general hospitals were identified from hospital databases. Notes were reviewed to confirm the technique and lack of conversion to an open procedure. Those who had immediate complications were excluded. A telephone questionnaire was conducted to answer questions related to long-term cosmetic and general satisfaction of the current procedure. Of the patients surveyed, 93% were happy or extremely happy with the current procedure, 48% experienced some wound-related issues (pain, infection), and 65% of those were at the umbilicus (a possible reflection of location and retrieval site for gallbladder). Cosmesis was rated less important than hospital cleanliness and experience of the surgeon. Overall satisfaction was high with the existing technique. The high rate of umbilical wound problems is an issue that will not be eradicated by introduction of single-port laparoscopic surgery.

    Two almost identical groups of 258 patients each who underwent surgery for the substitution of one or more than one cardiac valve were taken into consideration. After surgery all patients, with the exception of those who received a porcine allograph, were given coumarin drugs for 1 year for thrombosis prophylaxis. In the first group of patients operated in 1972 and 1973 the laboratory follow-up and the therapeutic range were neither constant nor uniform. In the case of the second group, which included patients operated in 1974 and 1975, adequate laboratory follow-up and constantly adequate therapeutic ranges were always kept. This retrospective study has shown a statistically significant decrease in mortality due to thromboembolism and to unknown causes in the second group of patients (x2 = 8,313, "p" less than 0,0025). A decrease of the non-lethal embolic complications was also noted in the second group of patients (x2 = 6,813, "p" less than 0,0025). On the other hand, bleeding complications were greater in the second group of patients (x2 = 3,485, "p" less than 0,05) and this was interpreted as secondary to the higher anticoagulation administered to the latter patients. The results indicate that an adequate coumarin anticoagulation seems able to decrease the incidence of lethal or non-lethal thromboembolic complications after cardiac valve replacement significantly.

    Background: The purpose of this study is to determine the type and frequency of pathological conditions around third molar teeth among randomly selected patient’s records in Oral and Maxillofacial Surgery, College of Dentistry, King Saud University, Riyadh. Materials and Methods: Totally, 281 patient panoramic radiographs were selected with detectable pathology among 570 files of patients seen in oral and maxillofacial surgery clinics 2 years retrospectively. Almost 17-55 years age (mean age 25.43) was selected. The following radiographs were analyzed for all pathology associated impacted teeth; dental caries, bone resorption, periodontitis, and apical pathology. Results: The study found caries, external bone resorption and periodontitis are highly frequent to mesioangular and horizontal in mandibular impacted third molar compared to maxillary impacted third molar. Overall result evaluated that tooth #28 related periodontitis is significant (P = 0.021), and tooth #38 related bone resorption, tooth #48 related root caries, bone resorption and apical pathology are highly significant (P = 0.000) comparing to others. This study also concluded the high frequency of root caries, bone resorption and apical pathology reported in relation to mandibular impacted third teeth. Significant results were also achieved with periodontitis in relation to mesiangular and vertical angulation of left impacted maxillary third molars. Conclusion: Prophylactic removal of impacted third molars is recommended in many studies to avoid future risk of associated pathology. Retained asymptomatic impacted third molars imply pathology that could be difficult in later ages as less morbidity in younger ages. PMID:25954064

    Transcanalicular lacrimal duct surgery has become more important over the past two decades. The aim of the study was to prove the prognostic value of postoperative lacrimal syringing and the testing of spontaneous drainage of lacrimal fluid immediately after tube removal. A total of 110 cases with postoperative lacrimal syringing and 183 cases with verification of the postoperative lacrimal fluid drainage performed between January 2001 and August 2008 were retrospectively evaluated. The indication for postoperative diagnostics was set by the investigator. The prognostic value of these two procedures was determined by using prognostic parameters (positive predictive value, PPV; negative predictive value, NPV) and analyzing recurrence nonexistence via Cox regression and Kaplan-Meier estimator. The observation period was limited to 12 months. Predominantly, recurrence was defined on the patient's satisfaction and absence of symptoms, which was determined with the help of a questionnaire. Postoperative verification of the lacrimal syringing is a suitable instrument to estimate surgical success within the first year after lacrimal surgery with a PPV of 92.31%. Testing of the spontaneous drainage of lacrimal fluid after tube removal reached a PPV of 63.33%. The proven prognostic value shows that syringing of the lacrimal duct and verification of spontaneous drainage should be integrated into postoperative care in a standardized manner. Hereby, early information for the patient about the expected result of the surgical procedure is enabled.

    Full Text Available Abstract Background Degenerative spinal stenosis and instability requiring multilevel spine surgery has been associated with large blood losses. Factors that affect perioperative blood loss include time of surgery, surgical procedure, patient height, combined anterior/posterior approaches, number of levels fused, blood salvage techniques, and the use of anti-fibrinolytic medications. This study was done to evaluate the efficacy of tranexamic acid in reducing blood loss in spine surgery. Methods This retrospective case control study includes 97 patients who had to undergo surgery because of degenerative lumbar spinal stenosis and instability. All operations included spinal decompression, interbody fusion and posterior instrumentation (4-5 segments. Forty-six patients received 1 g tranexamic acid intravenous, preoperative and six hours and twelve hours postoperative; 51 patients without tranexamic acid administration were evaluated as a control group. Based on the records, the intra- and postoperative blood losses were measured by evaluating the drainage and cell saver systems 6, 12 and 24 hours post operation. Additionally, hemoglobin concentration and platelet concentration were reviewed. Furthermore, the number of red cell transfusions given and complications associated with tranexamic acid were assessed. Results The postoperative hemoglobin concentration demonstrated a statistically significant difference with a p value of 0.0130 showing superiority for tranexamic acid use (tranexamic acid group: 11.08 g/dl, SD: 1.68; control group: 10.29 g/dl, SD: 1.39. The intraoperative cell saver volume and drainage volume after 24 h demonstrated a significant difference as well, which indicates a less blood loss in the tranexamic acid group than the control group. The postoperative drainage volume at12 hours showed no significant differences; nor did the platelet concentration Allogenic blood transfusion (two red cell units was needed for eight patients

    The purpose of this study was to analyze the probability and time course of fibrotic changes in breast reconstruction before or after postmastectomy radiotherapy (PMRT). Between 1995 and 2004, 109 patients were treated with PMRT at Tuebingen University and underwent heterologous (HL) or autologous (AL) breast reconstruction prior or subsequent to radiation therapy. Fibrosis of the reconstructed breast after radiotherapy was assessed using the Baker score for HL reconstructions and the Common Terminology Criteria for Adverse Events (CTCAE) for all patients. Actuarial rates of fibrosis were calculated for the maximum degree acquired during follow- up and at the last follow-up visit documented. Median time to follow-up was 34 months (3-227 months). Radiotherapy was applied with a median total dose of 50.4 Gy. A total of 44 patients (40.4%) received a boost treatment with a median dose of 10 Gy. Breast reconstruction was performed with AL, HL, or combined techniques in 20, 82, and 7 patients, respectively. The 3-year incidence of ≥ grade III maximum fibrosis was 20% and 43% for Baker and CTCAE scores, respectively. The corresponding figures for fibrosis at last follow-up visit were 18% and 2%. The 3-year rate of surgical correction of the contralateral breast was 30%. Initially unplanned surgery of the reconstructed breast was performed in 39 patients (35.8%). Boost treatment and type of cosmetic surgery (HL vs. AL) were not significantly associated with the incidence of fibrosis. We found severe fibrosis to be a frequent complication after PMRT radiotherapy and breast reconstruction. However, surgical intervention can ameliorate the majority of high grade fibrotic events leading to acceptable long-term results. No treatment parameters associated with the rate of fibrosis could be identified. (orig.)

    Evidence on the role of intravenous iron (IVI) supplementation after colorectal cancer (CRC) surgery is rather scant. This study was aimed at assessing the benefit of postoperative IVI administration after elective CRC surgery at our institution. This was a single-centre, retrospective observational study including all patients who underwent CRC surgery during 2014. Anaemia was defined as a haemoglobin (Hb) <13 g/dL, regardless of gender. Anaemic patients received 200 mg IVI up to three times a week to cover iron deficiency (IVI group). Those who did not receive IVI were placed on standard care (NIVI group). The primary outcome was the proportion of anaemic patients on post-operative day (POD)1 and POD30. Secondary outcomes included Hb changes from POD1 to POD30, transfusion requirements and complication rates. Of the 159 patients studied, 139 (87%) presented with anaemia: 47 (34%) of these received post-operative IVI and 92 (66%) did not. Patients in the IVI group had lower POD1 Hb levels compared to those in the NIVI group (p=0.001). On POD30, only 103 had their Hb measured (34 IVI, 69 NIVI). Anaemia was more prevalent and more severe among the patients in the IVI group (p=0.027), despite their greater increment in Hb (2.0±1.5 g/dL vs 1.1±1.2 g/dL; p=0.001). Eleven patients needed post-operative transfusions (7 IVI, 4 NIVI; p=0.044). There were no differences in post-operative complication rates between the groups. No IVI-related adverse events were recorded DISCUSSION: Compared with standard care, post-operative IVI administration to anaemic patients improved the recovery of Hb levels at POD30, without increasing post-operative complications.

    Full Text Available Background: Premature infants scheduled for surgery under general anesthesia are more prone to cardio-respiratory complications. Risk factors include post-conception age (PCA, cardiac and respiratory disease, anemia and opioid administration. This retrospective study evaluates the perioperative management and post-operative course (apnea and bradycardia in premature infants undergoing surgery for retinopathy of prematurity (ROP. Materials and Methods: We analyzed the pre-operative data, anesthesia chart and post-operative course of 52 former premature infants for 56 general anesthesia exposures for ROP surgery. Results: At the time of procedure, median PCA was 51 (36-60 weeks. 71% of the infants were above 46 weeks of PCA. Five infants had cardiac disease and four had a history of convulsion. Four infants had a pre-operative history of apneic spells. The airway was secured with either endotracheal tube (46 or supraglottic device (10. Fentanyl (0.5-1 μg/kg, paracetamol, topical anesthetic drops and/or peribulbar block were administered for analgesia. Extubation was performed in the operating room for 54 cases. Three infants had apnea post-operatively. Seven infants were shifted to neonatal intensive care unit either for observation or due to delayed recovery, persistent apneic spells and pre-existing cardio-respiratory disease. Conclusion: In the present study, intravenous paracetamol and topical anesthetics reduced the total intra-operative opioid requirement, which resulted in low incidence of post-operative apnea. Regional anesthesia may be considered in infants with high risk of post-operative apnea. Infants with PCA > 42 weeks and without any co-morbidity can be managed in post-anesthesia care unit.

    Laboratory hemostatic variables and parameters of rotational thromboelastometry (ROTEM) were evaluated for their ability to predict perioperative excessive blood loss (PEBL) after congenital cardiac surgery. Retrospective and observational. Single, large university hospital. The study comprised 119 children younger than 10 years old undergoing congenital cardiac surgery with cardiopulmonary bypass (CPB). Intraoperative excessive blood loss was defined as estimated blood loss≥50% of estimated blood volume (EBV). Postoperative excessive blood loss was defined as measured postoperative chest tube and Jackson-Pratt drainage≥30% of EBV over 12 hours or≥50% of EBV over 24 hours in the intensive care unit. PEBL was defined as either intraoperative or postoperative excessive blood loss. External temogram (EXTEM) and fibrinogen temogram (FIBTEM) were analyzed before and after CPB with ROTEM and laboratory hemostatic variables. Multivariate logistic regression was performed. Incidence of PEBL was 19.3% (n = 23). Independent risk factors for PEBL were CPB time>120 minutes, post-CPB FIBTEM alpha-angle, clot firmness after 10 minutes20%. Laboratory hemostatic variables were not significant in multivariate analysis. The risk prediction model was developed from the results of multivariate analysis. The area under the receiver operating characteristic curve was 0.94 (95% confidence interval: 0.90-0.99). Post-CPB ROTEM may be useful for predicting both intraoperative and postoperative excessive blood loss in congenital cardiac surgery. This study provided an accurate prediction model for PEBL and supported intraoperative transfusion guidance using post-CPB FIBTEM-A10 and EXTEM-A10. Copyright © 2016 Elsevier Inc.

    The aim of this retrospective investigation was to evaluate the position of the nasotracheal tube in the nose and to show its anatomical relationship with the maxillary sinus ostium. Fifty data sets from patients who had undergone endonasal intubation were analyzed for tube positioning. There was a drop-out of eight data sets due to missing information concerning tube size and mode. Tube positioning was determined at the maxillary sinus ostium in the intraoperatively generated three-dimensional X-ray data sets. The type of tube, the tube size, and the presence of maxillary sinusitis were analyzed 30 minutes after intubation. The tube was positioned in the middle nasal meatus in 35 (83.3%) patients and not in the middle nasal meatus in 7 (16.7%) patients. The difference in comparison with equal distribution was significant (P tubes are positioned in the middle nasal meatus. This result can be part of the answer to the question of the causal relationship between position of the breathing tube and the onset of maxillary sinusitis. The indications for prolonged nasotracheal intubation instead of orotracheal intubation or early tracheostomy should be considered carefully.

    For 75% of patients with trigeminal neuralgia (TN), the pain can be controlled with medication. For those who fail medication therapy, surgical options include microvascular decompression (MVD), percutaneous radiofrequency rhizotomy (RFR), and stereotactic radiosurgery (SRS). Few studies have explored the relative cost-effectiveness of these interventions, particularly in surgically naïve patients. A retrospective chart review performed between January 2003 and January 2013 identified a total of 89 patients who underwent surgical treatment for TN (MVD=27, RFR=23, SRS=39). Outcome measures included facial pain (excellent=no pain, no medications; good=no pain, medications required; fair=>50% decrease in pain; and poor=RFR=76.2±16, and SRS=74.5±12 (pRFR=4700±2200, and SRS=39,300±6000 (pRFR=52%, and SRS=28% (pRFR=74%, and SRS=31% (pRFR=59±76, and SRS=35±25. Mean quality adjusted pain-free years were MVD=1.58, RFR=2.28, and SRS=0.99. Cost-effectiveness calculations in US dollars showed MVD=31,800, RFR=2100, and SRS=39,600 (pRFR was the least expensive procedure, provided immediate relief, but was associated with the highest rates of facial numbness and recurrence. Based on cost-effectiveness, considering both cost and outcome, RFR was the most cost-effective, followed by MVD, and finally SRS. Copyright © 2015 Elsevier B.V. All rights reserved.

    Full Text Available Abstract Background It is unclear when it is safe to discharge patients with a diagnosis of Obstructive Sleep Apnea (OSA after ambulatory surgical procedures due to concern for postoperative respiratory compromise and hypoxemia. Our OSA patients undergoing ambulatory-type orthopedic procedures are monitored overnight in the PACU, thus we reviewed patient records to determine incidence of complications. Methods Two hundred and six charts of patients with preoperative diagnosis of OSA based on ICD-9 codes were reviewed for outcomes including episodes of hypoxemia. Univariate analysis followed by logistic regression and propensity analysis was performed to determine independent risk factors for hypoxemia and association with adverse outcomes. Results The majority of patients had regional anesthesia (95%. Thirty four percent of patients had hypoxemia in the PACU. Initial risk factors for hypoxemia identified by univariate analysis were BMI ≥ 35, increased age, history of COPD, upper extremity procedure, and use of peripheral nerve block. Independent risk factors identified by logistic regression were history of COPD (OR 3.64 with 95% CI 1.03-12.88 and upper extremity procedure (2.53, 1.36-4.68. After adjustment with propensity scores, adverse events were rare, and unplanned hospital admission after PACU stay was not increased with hypoxemia (11% vs 16% Conclusions Episodes of postoperative hypoxemia in OSA patients undergoing ambulatory surgery with regional anesthesia are not associated with increased adverse outcomes or unplanned hospital admission.

    Despite the variable results of published studies, it is imperative for ambulatory surgery centers to self-audit local cost-implications for post-operative nausea and vomiting (PONV) management. Our retrospective cost-audit assessed if there were comparative peri-anesthesia care cost-trends among patients who had undergone Low-Emetogenicity-Risk Procedures (LERP), Moderate-Emetogenicity-Risk Procedures (MERP) and Severe-Emetogenicity-Risk Procedures (SERP). This study was a review of Same Day Surgery Center practices in an academic university hospital setting during a three-year period (2010-2012). The patient lists were accessed from CIS and CITRIX App Bar for time audit and OR (operating room) schedule reports. Subsequently, OR pharmacy department ran a search for peri-operative anti-emetics and opioids that were billed for the patients at Same Day Surgery Center for the review period. The primary outcomes were the comparative costs/charges of these medications and comparative durations/ charges for these patients' stay in the post-anesthesia care unit (PACU). Secondary outcomes analyzed in the study included peri-anesthesia durations. A total of 8,657 patient records were analyzed. Almost all analyzed variables revealed statistically significant inter-variable positive correlations. The patients' age was significantly (P < 0.001) different among LERP/MERP/SERP patients (LERP: 48.8 +/- 14.7 years; MERP: 61.8 +/- 14.6 years; SERP: 51.3 +/- 14.5 years). In regards to primary and secondary outcomes, the statistical significant differences among LERP/MERP/SERP patients (after correcting for both patients' age as well as patients' sex) were only achieved for preoperative times (P = 0.002; Power = 0.9), operating room recovery times (P = 0.003; Power = 0.9), PACU stay times (P < 0.001; Power = 1.0), and PACU charges (P < 0.001; Power = 1.0). PACU stay times and PACU charges were significantly higher in patients who had undergone SERP as compared to patients who had

    To validate Aristotle basic complexity and Aristotle comprehensive complexity (ABC and ACC) and risk adjustment in congenital heart surgery-1 (RACHS-1) prediction models for in hospital mortality after surgery for congenital heart disease in a single surgical unit. Patients younger than 18 years, who had undergone surgery for congenital heart diseases from July 2007 to July 2013 were enrolled. Scoring for ABC and ACC scoring and assigning to RACHS-1 categories were done retrospectively from retrieved case files. Discriminative power of scoring systems was assessed with area under curve (AUC) of receiver operating curves (ROC). Calibration (test for goodness of fit of the model) was measured with Hosmer-Lemeshow modification of χ2 test. Net reclassification improvement (NRI) and integrated discrimination improvement (IDI) were applied to assess reclassification. A total of 1150 cases were assessed with an all-cause in-hospital mortality rate of 7.91%. When modeled for multivariate regression analysis, the ABC (χ2 = 8.24, P = 0.08), ACC (χ2 = 4.17 , P = 0.57) and RACHS-1 (χ2 = 2.13 , P = 0.14) scores showed good overall performance. The AUC was 0.677 with 95% confidence interval (CI) of 0.61-0.73 for ABC score, 0.704 (95% CI: 0.64-0.76) for ACC score and for RACHS-1 it was 0.607 (95%CI: 0.55-0.66). ACC had an improved predictability in comparison to RACHS-1 and ABC on analysis with NRI and IDI. ACC predicted mortality better than ABC and RCAHS-1 models. A national database will help in developing predictive models unique to our populations, till then, ACC scoring model can be used to analyze individual performances and compare with other institutes.

    The aim of this clinical investigation was to evaluate the clinical and radiologic outcomes of a single-step surgical procedure that includes functional endoscopic sinus surgery (FESS) and maxillary sinus elevation by the lateral window approach in patients with reversible contraindications to sinus elevation. Thirty-eight patients with insufficient bone height in the posterior maxilla caused by pneumatization of the sinus and with reversible ear-nose-throat (ENT) contraindications to sinus elevation were recruited for this investigation between January 2010 and January 2012. All patients were treated in a single session under general anesthesia for a total of 69 consecutive sinus augmentations. FESS was performed by an ENT specialist, and an oral surgeon carried out sinus elevation through the lateral window approach. Particulate xenograft was used beneath the sinus membrane. Intraoperative and postoperative complications (eg, membrane tears, rhinosinusitis, graft infection or loss) were reported. Nasal endoscopies were performed at 7, 14, and 30 days and 3 months after treatment. After a healing period of 6 months, 137 implants were inserted. Computed tomography scans were performed after 6 months and 1 year. Intraoperative membrane perforation occurred in only one case. No implant failures were recorded during the follow-up period. Radiologic and clinical findings showed the resolution of ENT disease and good bone graft integration after 1 year. A relapse of mucosal thickening observed in some patients did not influence the graft healing. Preliminary rhinosinusal evaluation by an ENT specialist and computed tomography of the ostiomeatal complex are necessary in patients needing maxillary sinus elevation. A single-step approach to FESS and sinus elevation is a predictable technique to manage patients with ENT reversible contraindications to sinus elevation.

    The purpose of the present study was to compare management of varicose veins by endovenous laser ablation (EVL) and a vein-sparing procedure (CHIVA: Conservatrice et Hémodynamique de l'Insuffisance Veineuse en Ambulatoire) for management of varicose veins. Data from 82 consecutive patients with great saphenous vein (GSV) reflux and primary varicose veins presenting to the vascular clinic at the Far Eastern Memorial Hospital between June and December 2005 were reviewed. Of these, 74 who met the inclusion criteria were included in this study. CHIVA was performed by a double division of the refluxing saphenous vein (i.e., proximal and distal ligation), and EVL was performed using 10-14 W beginning approximately 4 cm below the saphenofemoral junction to the level of the knee. Phlebectomy for significant branch varicose veins on the leg was routinely performed in all patients. Outcome measures included postoperative thrombophlebitis, bruising, pain, assessment of ultrasonographic and clinical symptoms (measured by the Venous Clinical Severity Score [VCSS]) and comparison of quality of life survey scores obtained preoperatively and postoperatively (measured by the Aberdeen Varicose Veins Score [AVVQ] and RAND-36). Patients were examined one week post-procedurally and again at 1, 3, 6, and 12 months. Endovenous laser ablation and CHIVA were performed on 54 and 20 patients, respectively. The EVL patients had significantly higher pain scores and bruising than the CHIVA group (pEVL and CHIVA; however, patients treated by EVL had significantly more pain postoperatively than those treated by CHIVA (p=0.003). Twenty-two of 54 (40.7%) and 3 of 17 (17.6%) patients in the EVL and CHIVA groups, respectively, required sclerotherapy for residual varicosities (p=0.026). Both groups benefited significantly from surgery in disease-specific perceptions. The CHIVA patients had less pain postoperatively and a significantly higher sclerotherapy-free period compared to patients in the EVL

    The incidence of cancer in the proximal third of the stomach is increasing. Laparoscopic proximal gastrectomy (LPG) seems an attractive option for the treatment of early-stage proximal gastric cancer but has not gained wide acceptance because of technical difficulties, including the prevention of severe reflux. In this study, we describe our technique for LPG with jejunal interposition (LPG-IP) and evaluate its safety and feasibility. In this retrospective analysis, we reviewed the data of patients with proximal gastric cancer who underwent LPG-IP (n = 22) or the same procedure with open surgery (OPG-IP; n = 68) between January 2008 and September 2011. Short-term surgical variables and outcomes were compared between the groups. The reconstruction method was the same in both groups, with creation of a 15 cm, single-loop, jejunal interposition for anastomosis. There were no differences in patient or tumor characteristics between the groups. Operation time was longer in the LGP-IP group (233 vs. 201 min, p = 0.0002) and estimated blood loss was significantly less (20 vs. 242 g, p < 0.0001). The average number of harvested lymph nodes did not differ between the two groups (17 vs. 20). There also were no differences in the incidence of leakage at the esophagojejunostomy anastomosis (9.1 vs. 7.4%) or other postoperative complications (27 vs. 32%). The number of times additional postoperative analgesia was required was significantly less in the LPG-IP group compared with the OPG-IP group (2 vs. 4, p < 0.0001). LPG-IP has equivalent safety and curability compared with OPG-IP. Our results imply that LPG-IP may lead to faster recovery, better cosmesis, and improved quality of life in the short-term compared with OPG-IP. Because of the limitations of retrospective analysis, a further study should be conducted to obtain definitive conclusions.

    Retrospective, single-center analysis of multilevel anterior fusion rates and health-related quality-of-life outcomes of mineralized collagen and bone marrow aspirate (BMA) in anterior interbody fusion cages for spine fusion surgery. To determine the ability and effectiveness of mineralized collagen and BMA to achieve multilevel anterior spinal fusion in adult spinal deformity patients when placed in carbon fiber reinforced polymer cages. High rates of postoperative pain and nonunion can result from spine fusion procedures. Factors that affect the success of fusion include patient comorbidities, position of implant, and mechanical and biological deficiencies, as well as the choice of bone graft replacement. Analysis of radiographic images and health-related quality-of-life outcomes was performed for a consecutive series of 22 prospectively enrolled adult spinal deformity patients with 104 total anterior fusion levels. Fusions were graded by 3 blinded surgeons not involved in the operative procedure; each fusion was graded on a 1-4 scale based on fusion mass appearance. Levels with an average fusion grade of 1-2.4 were classified as fused; levels with an average grade >2.5 were classified as not fused. The mean patient age was 51.5 years (range, 38-61) with 21 females. A total of 95% of anterior operative levels were graded as fused based on flexion/extension and full-length biplane radiographs at 1 year. Computed tomography grading showed a reduced fusion rate at 87% overall. There was a statistically significant improvement in the Oswestry Disability Index and Scoliosis Research Society 22-item questionnaire scores at 1 and 2 years after index surgery. Fusion rates in multilevel anterior spinal fusion using mineralized collagen and BMA are relatively low compared with fusion rates of 95% or more reported in the existing literature on long fusions with bone morphogenetic protein.

    Postoperative analgesic methods are suggested to have an impact on long-term prognosis after cancer surgery through opioid-induced immune suppression. We hypothesized that regional analgesia that reduces the systemic opioid requirement would be related to lower cancer recurrence and higher overall survival compared to intravenous patient-controlled analgesia (PCA) for lung cancer surgery. Records for all patients who underwent open thoracotomy for curative resection of primary lung cancer between 2009 and 2013 in a tertiary care hospital were retrospectively analyzed. Patients were divided by postoperative analgesic methods: PCA (n = 574), thoracic epidural analgesia (TEA, n = 619), or paravertebral block (PVB, n = 536). Overall and recurrence-free survivals were compared among 3 analgesic methods via a multivariable Cox proportional hazard model and a log-rank test after adjusting confounding factors using propensity score matching (PSM). Analgesic method was associated with overall survival (P= .0015; hazard ratio against TEA [95% confidence intervals]: 0.58 [0.39-0.87] for PCA, 0.60 [0.45-0.79] for PVB). After confounder adjustment using PSM, PVB showed higher overall survival than PCA (log-rank P= .0229) and TEA (log-rank P= .0063) while PCA and TEA showed no difference (log-rank P= .6). Hazard ratio for PVB was 0.66 [0.46-0.94] against PCA and 0.65 [0.48-0.89] against TEA after PSM. However, there was no significant association between the analgesic methods and recurrence-free survival (P= .5; log-rank P with PSM = .5 between PCA and TEA, .5 between PCA and PVB, .1 between TEA and PVB). Pain-control methods are not related to cancer recurrence. However, PVB may have a beneficial effect on overall survival of patients with lung cancer.

    Full Text Available Diabetic foot ulcers (DFU are one of the most important complications in people with diabetes mellitus. The present study was aimed to retrospectively review the efficacy of at least 1-week medical treatment before any surgical intervention in patients with Grade-3 and higher DFU according to Wagner's classification. A total of 52 patients (36 males and 16 females hospitalized and treated between June 2006 and February 2009 and had initially received therapeutic treatment (local wound care, antibiotic therapy and blood glucose regulation for a period of at least 1 week were included in the study. The level of amputation, rates of reulceration and mortality in both groups were recorded in the following period of 2 years. Group 1 (did not respond to preoperative medical intervention included 16 patients where a surgical debridement, flap or skin graft surgery was performed in 2 (12.5% patients, major amputation was performed in another 2 (12.5% patients and minor amputation was performed in the remaining 12 (75% patients. Of 36 patients in Group 2 (did respond to preoperative medical intervention, 5 (13.9% patients underwent the surgical debridement, flap or skin graft surgery, 8 (22.2% patients had a major amputation and the remaining 23 (63.9% patients lead to a minor amputation. The ulcer recurrence and mortality rates were obtained as 2 (12.5% and 2 (12.5% in Group 1 and 2 (5.6% and 1 (2.8% in Group 2, respectively. Despite the lower rates of ulcer recurrence and mortality in patients having adequate responses to initial treatment before surgical procedures were performed, no statistically significant difference was observed between the 2 groups. In addition, there was no statistically significant difference between the levels of amputation in both groups.

    The prevalence of anaemia is increasing globally. It has a close association with perioperative blood transfusion which, in turn, results in an increased risk of postoperative complications. Undesirable effects are not only limited to short-term, but also have long-term implications. Despite this, many patients undergo cardiac surgery with undiagnosed and untreated anaemia. We designed a retrospective, observational study to estimate the prevalence of anaemia in patients having cardiac surgery in Auckland District Health Board, blood transfusion rates and associated clinical outcome. Two hundred of seven hundred and twelve (28.1%) patients were anaemic. Red blood cell (RBC) transfusion rates were significantly higher in the anaemic group compared to the non-anaemic group (160 (80%) vs. 192 (38%), p-value rates for fresh frozen plasma (FFP), cryoprecipitate and platelets were also higher in the anaemic group. Anaemia was significantly associated with the development of new infection (14 (7%) vs. 15 (2.9%), p-value 0.0193, RR (CI 95%) 2.389 (1.175-4.859)), prolonged ventilation time (47.01 hours vs. 23.59 hours, p-value 0.0076) and prolonged intensive care unit (ICU) stay (80.23 hours vs. 50.27, p-value 0.0011). Preoperative anaemia is highly prevalent and showed a clear link with significantly higher transfusion rates and postoperative morbidity. It is vital that a preoperative management plan for the correction of anaemia should be sought to improve patient safety and outcome. © The Author(s) 2014.

    Population-based studies evaluating outcomes of different approaches for rectal cancer are scarce. We conducted a retrospective cohort study using the Nationwide Inpatient Sample database between 2008 and 2012. We compared the outcomes and costs among rectal cancer patients undergoing robotic, laparoscopic, or open surgeries using propensity scores for adjusted and matched analysis. We identified 194 957 rectal cancer patients. Over the 5-year period, the annual admission number decreased by 13.9%, the in-hospital mortality rate decreased by 32.2%, while the total hospitalization cost increased by 13.6%. Compared with laparoscopic surgery, robotic surgery had significantly lower length of stay (LOS) (OR 0.69, 95%CI 0.57-0.84), comparable wound complications (OR 1.08, 95%CI 0.70-1.65) and higher cost (OR 1.42, 95%CI 1.13-1.79), while open surgery had significantly longer LOS (OR 1.38, 95%CI 1.19-1.59), more wound complications (OR 1.49, 95%CI 1.08-1.79), and comparable cost (OR 0.92, 95%CI 0.79-1.07). There were no difference in in-hospital mortality among three approaches. Laparoscopic surgery was associated with better outcomes than open surgery. Robotic surgery was associated with higher cost, but no advantage over laparoscopic surgery in terms of mortality and complications. Studies on cost-effectiveness of robotic surgery may be warranted. © 2017 Wiley Periodicals, Inc.

    Hepatic surgery is a major abdominal surgery. Epidural analgesia may decrease the incidence of postoperative morbidities. Hemostatic disorders frequently occur after hepatic resection. Insertion or withdrawal (whether accidental or not) of an epidural catheter during coagulopathic state may cause an epidural hematoma. The aim of the study is to determine the incidence of coagulopathy after hepatectomy, interfering with epidural catheter removal, and to identify the risk factors related to coagulopathy. We performed a retrospective review of a prospective, multicenter, observational database including patients over 18 years old with a history of liver resection. Main collected data were the following: age, preexisting cirrhosis, Child-Pugh class, preoperative and postoperative coagulation profiles, extent of liver resection, blood loss, blood products transfused during surgery. International normalized ratio (INR) ≥1.5 and/or platelet count <80,000/mm defined coagulopathy according to the neuraxial anesthesia guidelines. A logistic regression analysis was performed to assess the association between selected factors and a coagulopathic state after hepatic resection. One thousand three hundred seventy-one patients were assessed. Seven hundred fifty-nine patients had data available about postoperative coagulopathy, which was observed in 53.5% [95% confidence interval, 50.0-57.1]. Maximum derangement in INR occurred on the first postoperative day, and platelet count reached a trough peak on postoperative days 2 and 3. In the multivariable analysis, preexisting hepatic cirrhosis (odds ratio [OR] = 2.49 [1.38-4.51]; P = .003), preoperative INR ≥1.3 (OR = 2.39 [1.10-5.17]; P = .027), preoperative platelet count <150 G/L (OR = 3.03 [1.77-5.20]; P = .004), major hepatectomy (OR = 2.96 [2.07-4.23]; P < .001), and estimated intraoperative blood loss ≥1000 mL (OR = 1.85 [1.08-3.18]; P = .025) were associated with postoperative coagulopathy. Coagulopathy is frequent (53

    We evaluate the challenges of laparoscopic colorectal surgery for diverticular disease. Retrospective study of elective laparoscopic colorectal procedures (LCP) performed 2002-2011. The study compares LCP for Diverticular disease (S group) with both LCP for other pathology (C1 group) and open procedures for diverticular disease (C2 group). Statistical analysis was performed using Fisher's exact test, Student "t" test and Mann Whitney U-test. The study included 194 LCP out of which 22 were in S group. Conversion rate in S group was 27.3% vs 9.9% in C1 group, p = 0.017. The mean operating time was significantly higher in S group (250 min) compared with 196 min in C1 group, p = 0.0004. The median length of hospital stay was 6 days in S group and 4 days in C group, p = 0.12. Both morbidities and mortality rates were not statistically different between the two groups. In the second part of the study we compare LCP with OCP performed for diverticular disease. LCP for Diverticular disease are technically challenging and should be attempted later in the learning curve. Copyright © 2013 Surgical Associates Ltd. Published by Elsevier Ltd.

    The main distinctive aspect of Juvenile Idiopathic Scoliosis (JIS) with respect to Adolescent Idiopathic Scoliosis (AIS) is the high risk of severe deformity and surgery. Approximately 70% of curves in patients with JIS progress and ultimately require surgery. There are presently very few studies with long-term follow-up of JIS and even fewer looking specifically at bracing Purpose To verify the effectiveness of a complete conservative treatment, including bracing and exercises, for JIS. Retrospective cohort observational study nested in a clinical prospective database of consecutive outpatients. Patient Sample Inclusion criteria: JIS, no previous treatment, all consecutive radiographies available from treatment start to end of growth (Risser sign 3). We found 30 patients, 27 females, 10 JIS type 1; mean age at first diagnosis was 7.8 +/-1.5 and mean treatment lasted 5.8 years. Cobb degrees 24.4+/-10 degrees, with 7 cases >30 degrees, and 2 > 45degrees. Outcome Measures Physiological measures. Radiographic and clinical data. Treatment (exercises alone, or elastic-rigid-highly rigid braces plus exercises) was tailored and continuously changed according to Cobb degrees, individual preferences, anthropometric characteristics, pubertal spurt, remaining growth, rotation, hump, lumbar curve take-off, and imbalance. The SOSORT Guidelines for patients' management have been followed. Funding and Conflict of Interest: no. 33.3% (95% Confidence Interval 16.4-50.2%) of patients worsened over the years. At the end of growth, 6.6% (0-15.5%) had surgical deformities (>45degrees). We observed a good correction in the first years of treatment until pubertal growth spurt, when progression was usually noted and treatment changed increasing corrective forces (hours or rigidity of bracing). 23 cases were followed up until they had two consecutive radiographies showing Risser sign 5 and showed stability. Conservative treatment initiated already in childhood may favorably change the

    Full Text Available Purpose. As a secondary analysis, we reassess the association of initial congenital cataract surgery times, compliance to amblyopia therapy, and visual outcomes for a long-term follow-up in a secondary IOL implantation. Methods. Retrospective review of records of all infants with congenital cataracts who underwent secondary IOL implantation in the Eye and ENT Hospital of Fudan University from January 1, 2001, to December 31, 2007, and the minimum follow-up period was 5 years. Multiple regression analysis was used and the possible confounding factors were also analyzed to assess the effect on visual outcome. Results. A total of 110 patients (male: 59.1% were included. The median (min–max age at cataract extraction and IOL implantation was 7.5 (3.0–15.0 and 35.0 (22.0–184.0 months, respectively, and the average follow-up period was 99.3 ± 23.6 months. The median (min–max BCVA at final follow-up was 0.20 (0.01–1.00. Compliance to amblyopia therapy was none, poor, and good in 21.8%, 24.5%, and 53.6%, respectively. Postoperative BCVA [logMAR, median (min–max 0.70 (0.00–2.00] linearly decreased with increasing cataract extraction time (per month (β=0.04, 95% CI: 0.03–0.06, p<0.0001 in multivariable models with laterality and compliance to amblyopia therapy adjusted. Good compliance to amblyopia therapy was associated with better BCVA (logMAR at last follow-up (β=−0.40, 95% CI = −0.53 to −0.27, p<0.0001 with laterality, opacity type, and extraction time adjusted. Conclusions. For Chinese infants with congenital cataract, an earlier primary congenital cataract surgery at an age of 3 to 15 months is associated with a better visual outcome. Good compliance to amblyopia therapy was also significant to visual outcome.

    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.

    Single event multilevel surgery (SEMLS) has become a standard intervention for children with cerebral palsy (CP). SEMLS proved to improve the gait in bilateral spastic cerebral palsy and those improvements can be maintained in the long term. However there is no evidence on the long-term outcome of unilateral SEMLS in children with unilateral spastic cerebral palsy. The gait analyses and clinical data of 14 children (9 male/5 female, mean age 12.1) with unilateral CP (6 children Gross Motor Function Classification System Scale level I and 8 children level II) were retrospectively reviewed at four time-points: preoperatively, 1year, 3-5 years and approximately 10 years after unilateral SEMLS. The Gait Profile Score (GPS) of the affected leg was used as a main and the number of fine tuning procedures as well as complications rate (Clavien-Dindo classification) as secondary outcome measures. The gait improved postoperatively and the GPS of the affected leg significantly declined by 3.73° which is well above the minimal clinical important difference of 1.6°. No deterioration of GPS occurred throughout the follow-up period. Therefore the postoperative improvement was maintained long-term. However, additional fine-tuning procedures had to be performed during the follow-up in 5 children and three complications occurred (one level II and two level III). The results indicate that children with unilateral cerebral palsy benefit from unilateral SEMLS and maintain gait improvements long-term. Copyright © 2016 Elsevier B.V. All rights reserved.

    To report our experience with EBRT combined with limb-sparing surgery in elderly patients (>70 years) with primary extremity soft tissue sarcomas (STS). Retrospectively analyzed were 35 patients (m:f 18:17, median 78 years) who all presented in primary situation without nodal/distant metastases (Charlson score 0/1 in 18 patients; ≥2 in 17 patients). Median tumor size was 10 cm, mainly located in lower limb (83%). Stage at presentation (UICC7th) was Ib:3%, 2a:20%, 2b:20%, and 3:57%. Most lesions were high grade (97%), predominantly leiomyosarcoma (26%) and undifferentiated pleomorphic/malignant fibrous histiocytoma (23%). Limb-sparing surgery was preceded (median 50 Gy) or followed (median 66 Gy) by EBRT. Median follow-up was 37 months (range 1-128 months). Margins were free in 26 patients (74%) and microscopically positive in 9 (26%). Actuarial 3- and 5-year local control rates were 88 and 81% (4 local recurrences). Corresponding rates for distant control, disease-specific survival, and overall survival were 57/52%, 76/60%, and 72/41%. The 30-day mortality was 0%. Severe postoperative complications were scored in 8 patients (23%). Severe acute radiation-related toxicity was observed in 2 patients (6%). Patients with Charlson score ≥2 had a significantly increased risk for severe postoperative complications and acute radiation-related side effects. Severe late toxicities were found in 7 patients (20%), including fractures in 3 (8.6%). Final limb preservation rate was 97%. Combination of EBRT and limb-sparing surgery is feasible in elderly patients with acceptable toxicities and encouraging but slightly inferior outcome compared to younger patients. Comorbidity correlated with postoperative complications and acute toxicities. Late fracture risk seems slightly increased. (orig.)

    Objective: To evaluate the short-term and oncologic outcomes of single-incision plus one port laparoscopic surgery (SILS+ 1) for sigmoid colon and upper rectal cancer. Methods: The clinic data of 46 patients with sigmoid colon and upper rectal cancer underwent SILS+ 1 at Department of General Surgery, Nanfang Hospital, Southern Medical University from September 2013 to September 2014 were retrospectively reviewed (SILS+ 1 group). After generating 1∶1 ration propensity scores given the covariates of age, gender, body mass index, American Society of Anesthesiologists score, surgeons, tumor location, the distance of tumor from anal, tumor diameter, and pathologic TNM stage, 46 patients with sigmoid colon and upper rectal cancer underwent conventional laparoscopic surgery (CLS) in the same time were matched as CLS group. The baseline characteristics and short-term outcomes were compared using t test, χ(2) test or Wilcoxon signed ranks test. Kaplan-Meier survival curves and Log-rank tests demonstrated the distribution of disease free survival. Results: The two study groups were well balanced with respect to the baseline characteristics of the propensity score derivation model. As compared to the CLS group, patients in SILS+ 1 group had a smaller incision ((6.9±1.1) cm vs . (8.4±1.2) cm, t =6.502, P =0.000), less estimated blood loss (20(11) ml vs . 50(30) ml, Z =2.414, P =0.016), shorter intracorporeal operating time ((67.0±25.8) minutes vs . (75.5±27.7) minutes, t =2.062, P =0.042) and significantly faster recovery course including shorter time to first ambulation ((46.7±20.3) hours vs . (78.6±28.0) hours, t =6.255, P =0.000), shorter time to first oral diet ((64.7±28.8) hours vs . (77.1±30.0) hours, t =2.026, P =0.047), shorter time of postoperative hospital stay ((7.8±2.2) days vs .

    Pyogenic spondylodiscitis is a rare disease, but its incidence is increasing. Over the last decade, spinal surgery has been modified to become minimally invasive. In degenerative spinal disorders, such minimally invasive surgery (MIS) reduces blood loss, muscular trauma, and the hospital stay. However, it is not known whether MIS also confers these benefits to patients with pyogenic spondylodiscitis. This retrospective cohort study compared the safety and efficacy of MIS and the conventional open surgical procedure in patients with pyogenic spondylodiscitis. The study cohort consisted of all consecutive patients who underwent surgery for thoracic or lumbar pyogenic spondylodiscitis that was not caused by previous surgery or tuberculosis in our tertiary-care institution between January 2003 and December 2011. Of the 148 eligible patients, 75 and 73 underwent MIS and open surgery, respectively. The 2 groups did not differ in terms of age, body mass index, American Society of Anaesthesiologists score, comorbidities, septic disease, or preoperative neurologic deficit. The 2 methods were associated with similar postoperative stays in the intensive care unit, overall hospital stays, complication rates, and postoperative survival. However, MIS was associated with a significantly shorter operating time, a lower perioperative need for blood products, and, as expected, an increased intraoperative fluoroscopy duration. Our 9-year experience suggests that MIS is safe and effective for spontaneous pyogenic thoracic and lumbar spondylodiscitis. Copyright © 2017 Elsevier Inc. All rights reserved.

    Pregnancies among morbidly obese women are associated with serious adverse maternal and neonatal outcomes. Our study objective is to evaluate the effect of bariatric surgery on obstetrical outcomes. We carried out a retrospective cohort study using the healthcare cost and utilization project - Nationwide Inpatient Sample from 2003 to 2011 comparing outcome of births among women who had undergone bariatric surgery with births among women with morbid obesity. Logistic regression was used to estimate the adjusted effect of bariatric surgery on maternal and newborn outcomes. There were 8 475 831 births during the study period (221 580 (2.6%) in morbidly obese women and 9587 (0.1%) in women with bariatric surgery). Women with bariatric surgery were more likely to be Caucasian and ≥35 years old as compared with morbidly obese women. As compared with women with morbid obesity, women with bariatric surgery had lower rates of hypertensive disorders, premature rupture of membrane, chorioamnionitis, cesarean delivery, instrumental delivery, postpartum hemorrhage, and postpartum infection. Induction of labor, postpartum blood transfusions, venous thromboembolisms, and intrauterine fetal growth restriction were more common in the bariatric surgery group. There were no differences observed in preterm births, fetal deaths, or reported congenital anomalies. In general, women who undergo bariatric surgery have improved pregnancy outcomes as compared with morbidly obese women. However, the bariatric surgery group was more likely to have venous thromboembolisms, to require a blood transfusion, to have their labor induced and to experience fetal growth restriction.

    Cosmetic surgery procedures are more complex for adolescents than for adults because there are more factors affecting patient satisfaction, especially psychological factors. This study was designed to find answers to four main questions: (1) whether postoperative satisfaction rates differ statistically between males and females, (2) whether postoperative satisfaction correlates significantly with the self-esteem, body image, life satisfaction trilogy, (3) what the postoperative patient satisfaction and cosmetic procedure rates are among adolescents by years, and (4) whether a statistically significant relationship exists between postoperative satisfaction and a willingness of adolescents to undergo another cosmetic surgery. The study enrolled 86 of 165 patients who underwent surgery between January 2001 and June 2005. A simple poll consisting of 12 simple questions was used to collect data. No statistically significant difference was found in postoperative satisfaction rates between males and females. The findings show that postoperative satisfaction is significantly related to self-esteem, body image, and life satisfaction. The patient satisfaction rate was 93.83%, and there was no increase in adolescent cosmetic surgery rates over the years. Adolescents are good candidates for cosmetic surgery, but patients must be evaluated carefully. Any suspicion about a patient's psychological status must result in a psychiatric consultation.

    To assess the relationship between the timing of radiotherapy and the risk of local failure in patients with endometrioid-type endometrial cancer who had undergone surgery and adjuvant external pelvic radiotherapy (with or without brachytherapy), but not chemotherapy. One hundred and seventy seven patients were analyzed in this study. The median follow-up of the survivors was 72 months. Radiotherapy was delivered after a median time of 14.6 weeks from surgery and the median overall treatment time was 6.4 weeks. The tumor relapsed in 32 (18.1%) patients after a median time of 21 months. The local recurrence (vaginal or central pelvic) occurred in 11 patients. The local recurrence rate was associated with tumor grade (p=0.02), myometrial invasion (p=0.046), FIGO stage (p=0.003), pathological node status (p=0.037) and time interval from surgery to radiotherapy using 9 weeks as the cut-off value (p=0.046), but not with the overall treatment time. All the local relapses occurred in patients who received adjuvant irradiation after an interval from surgery >9 weeks. The time interval from surgery to radiotherapy might affect the local recurrence rate in patients not receiving chemotherapy. Every possible effort should be made to start radiotherapy within 9 weeks, when radiotherapy only is deemed necessary as adjuvant treatment.

    Immediate loading has become a widely reported practice in implant dentistry. The aim of this study is to report on the 10-year clinical and radiographic outcomes of an immediate-loading treatment protocol that included flapless surgery. Forty-six patients were treated with 97 immediately loaded Mk IV implants (Nobel Biocare) with machined surface in the maxilla. Presurgically, a three-dimensional model of each patient's soft tissue and underlying alveolar bone anatomy was created and a surgical template was fabricated. A circular mucotome was used to punch out a 5-mm hole in the mucosa to avoid flap elevation. Control examinations were performed on the day of surgery and at 1, 2, 3, 6, 8, and 10 years after surgery. All prepared implant sites had intact buccal and lingual bone walls. The prefabricated provisional restorations showed excellent fit. Nine implants failed within 8 weeks of loading, resulting in a cumulative survival rate of 91% after 10 years of loading. The survival rates were 94% for implants supporting partial prostheses and 81% for implants supporting single restorations. Average marginal bone resorption was 1 mm during the first year, 0.4 mm during the second year, and 0.1 mm during the third year and after 10 years. The unchanged survival rate and the low average bone loss after 10 years confirm the feasibility of an immediate loading treatment protocol in the maxilla that included flapless surgery.

    Conclusion: Despite routine use of methylene blue dye test in 924 patients, there were only two positive tests. Whilst HPMB may demonstrate technical failure, this study suggests that there is no role for its routine use in primary bariatric surgery. Discontinuation of this practice would reduce risk of anaphylaxis to the dye, cost, and intra-operative time.

    Full Text Available Abstract Background Surveillance colonoscopy is commonly recommended following potentially curative surgery for colorectal cancer. We determined factors associated with patients undergoing a least one colonoscopy within five years of surgery. Methods In this historical cohort study, data on 3918 patients age 30 years or older residing in Alberta, Canada, who had undergone a potentially curative surgical resection for local or regional stage colorectal cancer between 1983 and 1995 were obtained from the provincial cancer registry, ministry of health and cancer clinic charts. Kaplan-Meier estimates of the probability of undergoing a post-operative colonoscopy were calculated for patient, tumor and treatment-related variables of interest. Results A colonoscopy was performed within five years of surgery in 1979 patients. The probability of undergoing a colonoscopy for those diagnosed in the 1990s was greater than for those diagnosed earlier (0.65 vs 0.55, P Conclusions The majority of patients undergo colonoscopy following colorectal cancer surgery. However, there are important variations in surveillance practices across different patient and treatment characteristics.

    Purpose: Chondrosarcoma is a rare malignant tumor of the cartilage affecting young adults. Surgery, followed by charged-particle irradiation, is considered the reference standard for the treatment of patients with grade I to II skull base chondrosarcoma. The present study was conducted to assess the effect of the quality of surgery and radiation therapy parameters on local control (LC) and overall survival (OS). Methods and Materials: From 1996 to 2013, 159 patients (median age 40 years, range 12-83) were treated with either protons alone or a combination of protons and photons. The median total dose delivered was 70.2 Gy (relative biologic effectiveness [RBE]; range 67-71). Debulking and biopsy were performed in 133 and 13 patients, respectively. Results: With a median follow-up of 77 months (range 2-214), 5 tumors relapsed based on the initial gross tumor volume. The 5- and 10-year LC rates were 96.4% and 93.5%, respectively, and the 5- and 10-year OS rates were 94.9% and 87%, respectively. A total of 16 patients died (13 of intercurrent disease, 3 of disease progression). On multivariate analysis, age <40 years and primary disease status were independent favorable prognostic factors for progression-free survival and OS, and local tumor control was an independent favorable predictor of OS. In contrast, the extent of surgery, dosimetric parameters, and adjacent organs at risk were not prognostic factors for LC or OS. Conclusions: Systematic high-dose postoperative proton therapy for skull base chondrosarcoma can achieve a high LC rate with a low toxicity profile. Maximal safe surgery, followed by high-dose conformal proton therapy, is therefore recommended.

    Serum creatinine is the most commonly used indicator of renal function, but its derivative, estimated glomerular filtration rate (eGFR), has been shown to be superior in non-surgical settings. It remains unknown if eGFR better predicts postoperative mortality in non-cardiac surgical patients. We thus tested the hypothesis that eGFR predicts 30-day mortality after non-cardiac surgery better than serum creatinine. We evaluated patients who had inpatient non-cardiac surgery of at least one hour duration during January 2006 to December 2011 at the Cleveland Clinic Main Campus and whose preoperative serum creatinine was measured within 30 days before surgery. The eGFR was calculated using the Chronic Kidney Disease-Epidemiology Collaboration equation. Preoperative eGFR was compared in a multivariable analysis with preoperative serum creatinine (both assessed as continuous variables) on the ability to predict 30-day mortality in all patients. Secondarily, the comparison was made within subgroups based on amount of blood loss, blood transfusion, and sex. There were 92,888 patients included in the final analysis. The eGFR was a modestly better discriminator of 30-day mortality than serum creatinine, with an estimated c-statistic (95% confidence interval) of 0.67 (0.65 to 0.68) for eGFR vs 0.61 (0.59 to 0.63) for serum creatinine (P serum creatinine. Nevertheless, a multivariable combination of baseline characteristics of American Society of Anesthesiologists physical status, age, and body mass index (all P serum creatinine did not change the c-statistic. The eGFR is a modestly better predictor of 30-day mortality than serum creatinine in patients having inpatient non-cardiac surgery. Given that eGFR is often reported by clinical laboratories and is otherwise easy to calculate, it should generally be used in preference to creatinine alone.

    Full Text Available OBJECTIVE: Mohs micrographic surgery is a specialized surgical procedure used to treat skin cancer. The purpose of this study was to better understand the profile of the patients who underwent the procedure and to determine how histology might be related to complications and the number of stages required for complete removal. METHODS: The records of patients who underwent Mohs micrographic surgery from October 2008 to November 2013 at the Dermatology Division of the Hospital of the Campinas University were assessed. The variables included were gender, age, anatomical location, histology, number of stages required and complications. RESULTS: Contingency tables were used to compare the number of stages with the histological diagnosis. The analysis showed that patients with superficial basal cell carcinoma were 9.03 times more likely to require more than one stage. A comparison between complications and histological diagnosis showed that patients with superficial basal cell carcinoma were 6.5 times more likely to experience complications. CONCLUSION: Although superficial basal cell carcinoma is typically thought to represent a less-aggressive variant of these tumors, its propensity for demonstrating “skip areas” and clinically indistinct borders make it a challenge to treat. Its particular nature may result in the higher number of surgery stages required, which may, as a consequence, result in more complications, including recurrence. Recurrence likely occurs due to the inadequate excision of the tumors despite their clear margins. Further research on this subtype of basal cell carcinoma is needed to optimize treatments and decrease morbidity.

    The aim of this study was to evaluate the efficacy of carbon nanoparticles in identifying lymph nodes and promoting parathyroid gland function recovery after thyroid carcinoma surgery along with central lymph node dissection. A total of 231 patients who underwent thyroid carcinoma surgery combined with central lymph node dissection were divided into two groups: the CN group (intraoperative carbon nanoparticles injections) and the control group (no injection). Datas were collected respectively on the pre-operative, 1st, 7th and 30th postoperative days and monthly thereafter. While the pathological results (e.g. amount of incidental removed parathyroid glands and lymph nodes dissected), complications (e.g. rates of vocal cord paralysis, the neuromuscular symptoms, hypocalcemia and hypoparathyroidism), as well as follow-up outcomes of the serum Ca2+ and PTH levels were gathered and measured to be included in. In regard to the results of the pathological tests, the control group had a relatively higher incidence of incidental parathyroidectomy when compared to the CN group (P  0.05). Carbon nanoparticles play a key role in accurately identifying lymph nodes, reducing mistaken excision of parathyroid glands, accelerating rapid recovery of parathyroid function during thyroid carcinoma surgery with central lymph node dissection, without increasing the probability of postoperative complications.

    There remains a dearth of information regarding the surgical complications following multilevel spine surgery in Parkinson's disease (PD) patients. This retrospective cohort study was performed to address this issue on a nationwide level using the Nationwide Inpatient Sample from 2001 to 2012. More than 25 postoperative variables were analyzed to assess the impact of fusion construct length on each variable. Subsequently, the same analysis was performed on admissions without PD. 4301 PD patients with spine fusion were identified, of whom 934 (21.7%) underwent fusion of at least three levels; the remaining 3367 underwent fusion of 1-2 levels. Patients with 3+ level fusions were more likely to suffer paraplegia (P=.001; OR=3.0; 95%CI=1.5-6.1), hematoma/seroma (P=.009; OR=1.9; 95%CI=1.2-3.2), IVC filter placement (P=.018; OR=2.1; 95%CI=1.1-3.9), RBC transfusion (Panemia (P1week (P<.001; OR=2.1; 95%CI=1.8-2.5), and a nonroutine discharge (P=.005; OR=1.9; 95%CI=1.4-2.4). 692,173 non-PD patients with spine fusion were identified; 123,964 (17.9%) underwent 3+ level fusion. Differences between 3+ versus 1-2 level fusions were similar to those in PD patient, but unlike PD patients, postoperative infection was significant while in-hospital mortality, PE and VTE were not. Fusion of at least three levels increased morbidity, mortality, and adverse discharge disposition compared with 1-2 level fusions. Nearly 80% of all spine fusions performed in the United States are fewer than three levels. These findings are worth considering during operative decision-making in both PD and non-PD patients.

    Full Text Available Objective: To study the distribution of weight for age standard score (Z score in pediatric cardiac surgery and its effect on in-hospital mortality. Introduction: WHO recommends Standard Score (Z score to quantify and describe anthropometric data. The distribution of weight for age Z score and its effect on mortality in congenital heart surgery has not been studied. Methods: All patients of younger than 5 years who underwent cardiac surgery from July 2007 to June 2013, under single surgical unit at our institute were enrolled. Z score for weight for age was calculated. Patients were classified according to Z score and mortality across the classes was compared. Discrimination and calibration of the for Z score model was assessed. Improvement in predictability of mortality after addition of Z score to Aristotle Comprehensive Complexity (ACC score was analyzed. Results: The median Z score was -3.2 (Interquartile range -4.24 to -1.91] with weight (mean±SD of 8.4 ± 3.38 kg. Overall mortality was 11.5%. 71% and 52.59% of patients had Z score < -2 and < -3 respectively. Lower Z score classes were associated with progressively increasing mortality. Z score as continuous variable was associated with O.R. of 0.622 (95% CI- 0.527 to 0.733, P < 0.0001 for in-hospital mortality and remained significant predictor even after adjusting for age, gender, bypass duration and ACC score. Addition of Z score to ACC score improved its predictability for in-hosptial mortality (δC - 0.0661 [95% CI - 0.017 to 0.0595, P = 0.0169], IDI- 3.83% [95% CI - 0.017 to 0.0595, P = 0.00042]. Conclusion: Z scores were lower in our cohort and were associated with in-hospital mortality. Addition of Z score to ACC score significantly improves predictive ability for in-hospital mortality.

Methods: A review of all patients undergoing cataract surgery with insertion of a CTR between July 2000 and June 2010 was conducted at The Royal Victorian Eye and Ear Hospital, a large tertiary teaching hospital in Victoria, Australia. Information relating to each patient's demographic details, preoperative assessment, surgical procedure, and postoperative assessment were obtained. Results: Eighty-four eyes of 82 patients were included in this study. The main indications for CTR insertion were previous trauma, pseudoexfoliation syndrome, and mature cataracts. Twenty-one eyes (25.0% did not have any obvious preoperative indication. A posterior capsule tear was the most common intraoperative complication (3.6%. An intraocular lens was successfully implanted in the bag in 72 eyes (85.7%. Postoperatively, the most common complications were a decentered intraocular lens (8.3% and persistent corneal edema (6.0%. Overall, 61 eyes (72.6% had better postoperative visual acuity compared with preoperative acuity, with 67 patients (79.8% achieving vision of 20/40 or better. Conclusion: For the majority of cases, CTR use in complex cataract surgeries is associated with improved postoperative outcomes. CTR implantation is most commonly required in patients with known risk factors for zonular instability. Keywords: capsular tension ring, cataract extraction, indications, outcomes

    To evaluate the clinical outcome of fully edentulous patients in the maxilla, who were treated with immediately loaded implant-supported cross-arch bridges using computer-aided implant surgery. The clinical outcome of 15 consecutive patients (5 males and 10 females) with a mean age of 52 years (range 40 to 70), with edentulous arches and treated with implant-supported cross-arch bridges was evaluated. Two computed tomography scans were performed, the first with the patient wearing the denture/radiographic guide and the radiographic index, and the second of the denture alone. The guided flapless surgical procedure was performed under local anaesthesia. Ninety implants were placed. The implant length ranged from 10 to 13 mm and the implant diameter was either 4.3 or 5 mm. All implants were immediately loaded with screw-retained provisional acrylic prostheses prepared in advance and delivered immediately after surgery. Clinical and radiographic follow-up visits were scheduled at 6, 12 and 18 months from surgery; implant survival rate, marginal bone levels, patient satisfaction and any complications were recorded. After the follow-up period of 18 months, two patients each lost one implant. After 18 months, patients lost, on average, 1.6 mm of peri-implant marginal bone. A patient satisfaction questionnaire at 18 months revealed a very high level of satisfaction with the treatment. Although limited by the number of patients, it can be concluded that software- and computed tomography-guided surgical planning for completely edentulous arches provides reliable results with high success rates.

    Immediate loading of dental implants shortens the treatment time and makes it possible to give the patient an esthetic appearance during the whole treatment period. The aim of the present study was to evaluate an immediate-loading treatment protocol, which included flapless surgery, implants placed in predetermined positions and connected to prefabricated provisional restorations, and the 3-year clinical results. A total of 97 Brånemark System Mk IV implants (Nobel Biocare AB, Gothenburg, Sweden) with a machined surface were inserted in the maxillas of 46 patients. A presurgical three-dimensional model of the patients' soft tissue and underlying alveolar bone anatomy was created, which allowed the clinician to place the implants in predetermined positions and connect them to prefabricated provisional restorations. A surgical template with drilling guides corresponding to each implant was used. The apical part of the master guide was equipped with a circular "mucotome," which punched out a 5 mm hole in the mucosa to eliminate the need for flap elevation. The patients received 25 fixed partial prostheses and 27 single-tooth restorations. Bone quality and quantity were assessed. Radiographic examinations were performed on the day of surgery/loading and at the 1-, 2-, and 3-year follow-up visits. All implant sites showed intact buccal and lingual bone walls during surgery, confirming the accuracy of the bone-mapping procedure. The prefabricated temporary restorations fitted, meaning that the implants were positioned clinically in the same way as on the cast. Nine implants in eight patients failed during the first 8 weeks of loading. This resulted in a cumulative survival rate of 91% after 3 years of prosthetic load. The survival rate of splinted implants was 94%. The number of failed implants was significantly higher in cases of single-tooth replacements and placement in soft bone sites and smokers. The failed implants were successfully replaced according to a two

    The primary aim of this study was to compare preoperative assessments with postoperative outcomes from patients undergoing foot and ankle revisions and/or complex reconstructions with tendon and/or nerve involvement using cryopreserved human amniotic membrane and umbilical cord (cHAM/UC). We hypothesized complex foot and ankle surgery using amniotic membrane would be an effective treatment leading to reduced pain and improved functional outcomes. Fourteen patients (6 male and 8 female) underwent open foot and ankle surgery during the study period. All 14 patients included in this cohort reported improvement, namely, lessened pain intensity both on the American Orthopedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale and the pain numeric rating scale (NRS), as well as improved functional status. The mean AOFAS score improved from 50 (range, 17-79) preoperatively to 85 (range, 67-100) postoperatively. The mean NRS score also improved from 8 (range, 4-10) preoperatively to 2 (range, 0-6) postoperatively with a mean percent change in pain NRS of 78% (range 17-100%). Both outcome-scoring systems showed statistically significant differences (p < .0001) when we compared the preoperative and postoperative results. All patients included in the cohort showed improvement in both outcome measures. Further study of long-term endpoints is warranted.

    Pre- and/or intra-operative use of diuretics, angiotensin-converting enzyme inhibitors (ACE-I) or angiotensin II receptor blockers (ARB) constitutes a potentially modifiable risk factor for postoperative acute kidney injury (AKI). It has been studied whether use of these drugs predicts AKI after cardiac surgery. The objective of this study was to examine whether administration of these agents was independently associated with AKI after non-cardiac surgery. This was a retrospective observational study. Inclusion criteria were adult patients (age ≥ 18) who underwent non-cardiac surgery under general anesthesia from 2007 to 2009 at Kyoto Katsura Hospital. Exclusion criteria were urological surgery, missing creatinine values, and preoperative dialysis. The exposures of interest were pre- and/or intra-operative use of diuretics or ACE-I/ARB. Outcome variables were postoperative AKI as defined by the AKI Network (increase in creatinine ≥ 0.3 mg/dL or 150% within 48 hours, or urine output 6 hours). Multivariable logistic regression analyses were conducted and adjusted for potential confounders. Propensity scores (PS) for receiving diuretics or ACE-I/ARB therapy were estimated and PS adjustment, PS matching, and inverse probability weighting were performed. There were 137 AKI cases (5.0%) among 2,725 subjects. After statistical adjustment for patient and surgical characteristics, odds (95% CI) of postoperative AKI were 2.07 (1.10-3.89) (p = 0.02) and 0.89 (0.56-1.42) (p = 0.63) in users of diuretics and ACE-I/ARB, respectively, compared with non-users. PS adjustment, PS matching, and inverse probability weighting yielded similar results. The effect size of diuretics was significantly greater in the patients with lower propensity for diuretic use (p for interaction diuretics, but not ACE-I/ARB, was independently associated with postoperative AKI after non-cardiac surgery, especially in patients with low propensity for diuretic use. It might be reasonable to withhold

    In an attempt to maximize treatment outcomes, refractive surgery techniques are being directed toward customized ablations to correct not only lower-order aberrations but also higher-order aberrations specific to the individual eye. Measurement of the entirety of ocular aberrations is the most definitive means to establish the true effect of refractive surgery on image quality and visual performance. Whether or not there is a statistically significant difference in induced higher-order corneal aberrations between the VISX Star S4 (Abbott Medical Optics, Santa Ana, California) and the WaveLight EX500 (Alcon, Fort Worth, Texas) lasers was examined. A retrospective analysis was performed to investigate the difference in root-mean-square (RMS) value of the higher-order corneal aberrations postoperatively between two currently available laser platforms, the VISX Star S4 and the WaveLight EX500 lasers. The RMS is a compilation of higher-order corneal aberrations. Data from 240 total eyes of active duty military or Department of Defense beneficiaries who completed photorefractive keratectomy (PRK) or laser in situ keratomileusis (LASIK) refractive surgery at the Wilford Hall Ambulatory Surgical Center Joint Warfighter Refractive Surgery Center were examined. Using SPSS statistics software (IBM Corp., Armonk, New York), the mean changes in RMS values between the two lasers and refractive surgery procedures were determined. A Student t test was performed to compare the RMS of the higher-order aberrations of the subjects' corneas from the lasers being studied. A regression analysis was performed to adjust for preoperative spherical equivalent. The study and a waiver of informed consent have been approved by the Clinical Research Division of the 59th Medical Wing Institutional Review Board (Protocol Number: 20150093H). The mean change in RMS value for PRK using the VISX laser was 0.00122, with a standard deviation of 0.02583. The mean change in RMS value for PRK using the

    Full Text Available Background: Chronic subdural hematoma (CSDH is a very common clinical emergency encountered in neurosurgery. While both general anesthesia (GA and monitored anesthesia care (MAC can be used during CSDH surgery, MAC is the preferred choice among surgeons. Further, while dexmedetomidine (DEX is reportedly a safe and effective agent for many diagnostic and therapeutic procedures, there have been no trials to evaluate the safety and efficacy of DEX vs. sufentanil in CSDH surgery. Objective: To evaluate the safety and efficacy of DEX vs. sufentanil in MAC during burr-hole surgery for CSDH.Methods: In all, 215 fifteen patients underwent burr-hole surgery for CSDH with MAC and were divided into three groups: Group D1 (n=67, DEX infusion at 0.5 μg·kg–1 for 10 min, Group D2 (n=75, DEX infusion at 1 μg·kg–1 for 10 min, and Group S (n=73, sufentanil infusion 0.3 μg·kg–1 for 10 min. Ramsay sedation scale (RSS of all three groups was maintained at 3. Anesthesia onset time, total number of intraoperative patient movements, hemodynamics, total cumulative dose of DEX, time to first dose and amount of rescue midazolam or fentanyl, percentage of patients converted to alternative sedative or anesthetic therapy, postoperative recovery time, adverse events, and patient and surgeon satisfaction scores were recorded.Results: The anesthesia onset time was significantly less in group D2 (17.36±4.23 vs. 13.42±2.12 vs. 15.98±4.58 min, respectively, for D1, D2, S; P<0.001. More patients in groups D1 and S required rescue midazolam to achieve RSS=3 (74.63% vs. 42.67% vs. 71.23%, respectively, for D1, D2, S; P<0.001. However, the total dose of rescue midazolam was significantly higher in group D1 (2.8±0.3 vs. 1.9±0.3 vs. 2.0±0.4 mg, respectively, for D1, D2, S; P<0.001. The time to first dose of rescue midazolam was significantly longer in group D2 (17.32±4.47 vs. 23.56±5.36 vs. 16.55±4.91 min, respectively, for D1, D2, S; P<0.001. Significantly fewer

    Several studies point in the direction that the Global Trigger Tool for Measuring Adverse Events (GTT) published by the Institute for Healthcare Improvement (IHI) is an appropriate method to detect adverse events with high specificity, sufficient sensitivity and adequate interrater and intrarater reliability. After passing a certain training period, rating teams in healthcare institutions can successfully detect and reliably compare adverse event rates on local and national levels. To date there exist no published relevant data specifically for departments of cardiovascular surgery. In this single-center, retrospective study adverse event rates were detected using GTT for a department of cardiovascular surgery in a Viennese hospital. Having begun to establish a risk management system in the year 2008, 120 case histories were rated by a trained team for the years 2009 and 2012 each (240 in total). From 2009 to 2012 the detection rate for adverse events improved significantly from 21.1 to 42.8 events per 1,000 patient days. This change was in agreement with an improvement in the detection rate of adverse events per 100 hospital admissions (from 43.7 to 80.0) as well as an improvement in the detection rate of the proportion of patients suffering from adverse events (from 24.4 % to 42.5 %). In the course of the introduction and continuous optimization of a risk management system, the detection rate of adverse events, as measured with GTT, could be brought up to international standards. Thus, the utility of GTT as a possible instrument to help increase patient safety and improve quality could also be established at a department of cardiovascular surgery. Copyright © 2017.

    Current protocols for venous thromboembolism (VTE) prophylaxis after craniofacial surgery (CFS) vary widely with substantial disagreements in both indications and managements. An evidence-based approach to this issue requires the following: the incidence of postoperative VTE, comorbidities associated with coagulopathy, risk reduction after VTE prophylaxis, and complications attributable to prophylaxis. This study addresses the first two. Retrospective cross-sectional study. Discharge data from 64,170 patients undergoing CFS between 2008 and 2013 extracted from the Healthcare Cost and Utilization Project Nationwide Inpatient Sample were analyzed. The outcome measures extracted were: deep venous thrombosis, pulmonary embolism, demographic data, common comorbidities, length of stay, total cost, and discharge outcome. Diagnoses of deep venous thrombosis or pulmonary embolism, collectively classified as VTE, were observed in 355 (0.55%) of 64,170 patients discharged after CFS. Other surgeries exhibited a VTE rate of 1.17%. Men exhibited nearly double the incidence of VTE relative to women (0.69% compared with 0.37% respectively, P use did not exhibit any significant association (odds ratio, 0.94; P = 0.679). Afflicted patients experienced 4.60 times longer hospital stays averaging 23.8 days (95% confidence interval, 21.4-26.2; P use of VTE chemoprophylaxis is appropriate.

    Objectives Previous studies demonstrated women presenting with acute coronary syndrome (ACS) have poor outcomes when compared with men ‘the gender gap phenomenon’. The impact of prior coronary artery bypass graft (CABG) on women presenting with ACS is unknown. We hypothesised that the gender gap is altered in ACS patients with prior CABG. The aim of this study was to evaluate patients presenting with ACS according to their gender and history of prior CABG. Design Retrospective, observational (cohort) study. Setting Data were collected from hospital-based registry of patients hospitalised with ACS in Doha, Qatar, from 1991 through 2010. The data were analysed according to their gender and history of prior CABG. Participants A total of 16 750 consecutive patients with ACS were studied. In total, 693 (4.3%) patients had prior CABG; among them 125 (18%) patients were women. Primary and secondary outcome measures Comparisons of clinical characteristics, inhospital treatment, and outcomes, including inhospital mortality and stroke were made. Results Women with or without prior CABG were older, less likely to be smokers, but more likely to have diabetes mellitus (DM), hypertension and renal impairment than men (p=0.001). Women were less likely to receive reperfusion and early invasive therapies. When compared with men, women without prior CABG carried higher inhospital mortality (11% vs 4.9%; p=0.001) and stroke rates (0.9% vs 0.3%; p=0.001). Female gender was independent predictor of poor outcome. Among prior CABG patients, despite the fact that women had worse baseline characteristics and were less likely to receive evidence-based therapy, there were no significant differences in mortality or stroke rates between the two groups. Conclusions Consistent with the world literature, women presenting with ACS and without prior CABG had higher death rates compared with men. Patients with prior CABG had comparable death rates regardless of the gender status. PMID:23194954

    Background Minimally invasive parathyroidectomy (MIP) for primary hyperparathyroidism is dependent upon accurate prediction of single-gland disease on the basis of preoperative imaging and biochemistry. The aims of this study were to validate currently available predictive models of single-gland disease in two UK cohorts and to determine if these models can facilitate MIP. Methods This is a retrospectively cohort study of 624 patients who underwent parathyroidectomy for primary hyperparathyroidism in two centres between July 2008 and December 2013. Two recognised models: CaPTHUS (preoperative calcium, parathyroid hormone, ultrasound, sestamibi, concordance imaging) and Wisconsin Index (preoperative calcium, parathyroid hormone) were validated for their ability to predict single-gland disease. Results The rates of single- and multi-gland disease were 491 (79.6%) and 126 (20.2%), respectively. Cure rates in centres 1 and 2 were 93.2% and 93.8%, respectively (P = 0.789). The positive predictive value (PPV) of CaPTHUS score . 3 in predicting single-gland disease was 84.6%, compared with 100% in the original report. CaPTHUS . 4 and 5 had a PPV of 85.1 and 87.1, respectively. There were no differences in Wisconsin Index (WIN) between patients with single- and multi-gland (P = 0.573). A WIN greater than 1600 and weight of excised gland greater than 1 g had a positive predictive value of 86.7% for single-gland disease. Conclusions The use of CaPTHUS and WIN indices without intraoperative adjuncts (such as IOPTH) had the potential to result in failure to cure in up to 15% (CaPTHUS) and 13% (WIN) of patients treated by MIP targeting a single enlarged gland.

    In the developing world, most patients with hepatocellular carcinoma present with advanced-stage disease, considered to be incurable based on current therapeutic algorithms. Here, we demonstrate that curative liver resection is achievable in a portion of Peruvian patients not addressed by these treatment algorithms. We conducted a retrospective cohort study of 253 hepatocellular carcinoma patients that underwent a curative hepatectomy between 1991 and 2011 at the National Cancer Institute of Peru. The median age of the cohort was 36 years, and merely 15.4% of the patients displayed cirrhosis. The average tumor size was over 14 cm in diameter, resulting in 76.3% of major hepatectomies performed. The 5- and 10-year survival probability estimates were 37.5% and 26.2%, respectively. Age (>44 vs. ≤44 years old; P = 0.005), tumor size (>10 cm vs. ≤10 cm in diameter; P = 0.009), cirrhosis (P < 0.001), satellite lesions (P < 0.001), macroscopic vascular invasion (P < 0.001), allogeneic blood transfusion (P = 0.011), and spontaneous rupture of the tumor (P = 0.006) were independent predictive factors for prognosis. Hepatocellular carcinomas in Peru are characterized by a distinct clinical presentation with notable features compared with those typically described throughout relevant literature. Despite a large number of advanced-stage hepatocellular carcinomas, the outcomes of liver resection observed in the present study were in good standing with the results previously described in other series. It thus appears that staging systems and associated therapeutic algorithms designed for use in the developed world remain inadequate in certain populations, especially in the context of Peruvian patients. Our findings suggest that clinicians in the developing world should reconsider management guidelines pertaining to hepatocellular carcinoma. Indeed, we hypothesize that, in developing countries, a strict adherence to these therapeutic algorithms might create a selection bias

    The early risk of stroke after transient ischemic attack (TIA)/stroke is of the order of 5-10% at 1 week and 10-20% at 3 months. Even if carotid endarterectomy (CEA) is the treatment of choice in symptomatic internal carotid artery stenosis, the timing of carotid intervention after acute stroke is not yet codified. The authors want to determinate whether early CEA is safely carried out in the first few hours (stroke/death) in these cases is comparable with the results of those treated by delayed/deferred surgery (range, 48 hours-24 weeks). In 4 years, the authors performed 1,184 CEA (285 symptomatic). Five groups were formed from 285 symptomatic patients, according to interval between TIA/stroke onset and performance of CEA: G1, less than 48 hours; G2, 48 hours-2 weeks; G3, 2-4 weeks; G4, 4-8 weeks; G5, 8-24 weeks. Surgery was never performed on patients with disabling neurological deficit (modified Rankin Scale, 5) at the time of admittance, cerebral lesions greater than 3 cm at magnetic resonance/computed tomography scan, presence or suspect of parenchymal hemorrhage associated with ischemic damage, condition considered unfit for surgery (American Society of Anesthesiology classification grade V), and occlusion of the cerebral middle artery. Neurological and diagnostic examinations (duplex-scanning and computed tomography/magnetic resonance scan) were used in determining the selection for early CEA. Cumulative TIA/stroke/death rate after CEA was 3.8% (11/285) and at 30 days was 2.8% (8/285). The cumulative TIA rate after CEA and at 30 days was 0% (0/285). The cumulative stroke rate after CEA was 3.5% (10/285) and at 30 days was 2.4% (7/285). The cumulative death rate after CEA and at 30 days was 0.3% (1/285). Stroke rate after CEA in each group was: G1 4.2% (3/70); G2 3.2% (2/61); G3 0% (0/22); G4 3.4% (1/29); G5 3.8% (4/103). Any statistically significant difference between G1 and the other four groups was not detected with regard to postoperative stroke: G1 (4

    Full Text Available BACKGROUND: Despite the best standard treatment, optimal cytoreductive surgery (CRS and platinum/taxane-based chemotherapy, prognosis of advanced epithelial ovarian carcinoma (EOC remains poor. Recently, CRS plus hyperthermic intraperitoneal chemotherapy (HIPEC has been developed to treat peritoneal carcinomatosis (PC. This study was to evaluate the efficacy and safety of CRS+HIPEC to treat PC from advanced/recurrent EOC. METHODS: Forty-six PC patients from advanced EOC (group A or recurrent EOC (group B were treated by 50 CRS+HIPEC procedures. The primary endpoints were progression-free survival (PFS and overall survival (OS; the secondary endpoints were safety profiles. RESULTS: The median OS was 74.0 months [95% confidence interval (CI 8.5-139.5] for group A versus 57.5 months (95% CI 29.8-85.2 for group B (P = .68. The median PFS was not reached for group A versus 8.5 months (95% CI 0-17.5 for group B (P = .034. Better median OS correlated with peritoneal cancer index (PCI 20 group, P = .01, complete cyroreduction (residual disease ≤ 2.5 mm [79.5 months for completeness of cytoreduction (CC score 0-1 vs 24.3 months for CC 2-3, P = .00], and sensitivity to platinum (65.3 months for platinum-sensitive group vs 20.0 for platinum-resistant group, P = .05. Serious adverse events occurred in five patients (10.0%. Multivariate analysis identified CC score as the only independent factor for better survival. CONCLUSION: For advanced/recurrent EOC, CRS+HIPEC could improve OS with acceptable safety.

    Healthcare costs in the United States (U.S.) are rising. As outcomes improve, such as decreased length of stay and decreased mortality, it is expected that costs should go down. The aim of this study is to analyze hospital charges, cost of care, and mortality in bariatric surgery over time. A retrospective analysis of the Nationwide Inpatient Sample (NIS) database was performed. Adults with morbid obesity who underwent gastric bypass or sleeve gastrectomy were identified by ICD-9 codes. Multivariate analyses identified independent predictors of changes in hospital charges and in-hospital mortality. Results were adjusted for age, race, gender, Charlson comorbidity index, surgical approach (open versus laparoscopic), hospital volume, and insurance status. In order to estimate baseline surgical inflation, changes in hospital charges over time were also calculated for appendectomy. From 1998 to 2011, 209,106 patients were identified who underwent bariatric surgery. Adjusted in-hospital mortality for bariatric surgery decreased significantly by 2003 compared to 1998 (p bariatric surgery admission was 130 % from 1998 to 2011. Charges per stay increased by 2.1 % annually for bariatric surgery compared to 5.5 % for appendectomy. In-hospital mortality rate following bariatric surgery underwent a ninefold decrease since 1998 while maintaining surgical inflation costs less than appendectomy. Innovation in bariatric surgical technique and technology has resulted in improvement of outcomes while providing overall cost savings.

    There is good evidence that radiotherapy is beneficial in advanced rectal cancer, but its application in Italy has not been investigated. We conducted a nationwide survey among members of the Italian Society of Colo-Rectal Surgery (SICCR) on the use of radiation therapy for rectal cancer in the year 2005. Demographic, clinical and pathologic data were retrospectively collected with an online database. Italy was geographically divided into 3 regions: north, center and south which included the islands. Hospitals performing 30 or more surgeries per year were considered high volume. Factors related to radiotherapy delivery were identified with multivariate analysis. Of 108 centers, 44 (41%) responded to the audit. We collected data on 682 rectal cancer patients corresponding to 58% of rectal cancers operated by SICCR members in 2005. Radiotherapy was used in 307/682 (45.0%) patients. Preoperative radiotherapy was used in 236/682 (34.6%), postoperative radiotherapy in 71/682 (10.4%) cases and no radiotherapy in 375 (55.0%) cases. Of the 236 patients who underwent preoperative radiotherapy, only 24 (10.2%) received short-course radiotherapy, while 212 (89.8%) received long-course radiotherapy. Of the 339 stage II-III patients, 159 (47%) did not receive any radiotherapy. Radiotherapy was more frequently used in younger patients (P < 0.0001), in patients undergoing abdominoperineal resection (APR) (P < 0.01) and in the north and center of Italy (P < 0.001). Preoperative radiotherapy was more frequently used in younger patients (P < 0.001), in large volume centers (P < 0.05), in patients undergoing APR (P < 0.005) and in the north-center of Italy (P < 0.05). Our study first identified a treatment disparity among different geographic Italian regions. A more systematic audit is needed to confirm these results and plan adequate interventions.

To compare perioperative complication rates following adult cervical deformity corrective surgery between a prospective multicenter database for patients with cervical deformity (PCD) and the Nationwide Inpatient Sample (NIS). Retrospective review of prospective databases. A total of 11,501 adult patients with cervical deformity (11,379 patients from the NIS and 122 patients from the PCD database). Perioperative medical and surgical complications. The NIS was queried (2001-2013) for cervical deformity discharges for patients ≥18 years undergoing cervical fusions using International Classification of Disease, Ninth Revision (ICD-9) coding. Patients ≥18 years from the PCD database (2013-2015) were selected. Equivalent complications were identified and rates were compared. Bonferroni correction (pdatabases. A total of 11,379 patients from the NIS database and 122 patiens from the PCD database were identified. Patients from the PCD database were older (62.49 vs. 55.15, pdatabase. The PCD database had an increased risk of reporting overall complications than the NIS (odds ratio: 2.81, confidence interval: 1.81-4.38). Only device-related complications were greater in the NIS (7.1% vs. 1.1%, p=.007). Patients from the PCD database displayed higher rates of the following complications: peripheral vascular (0.8% vs. 0.1%, p=.001), gastrointestinal (GI) (2.5% vs. 0.2%, pdatabases (p>.004). Based on surgicalapproach, the PCD reported higher GI and neurologic complication rates for combined anterior-posterior procedures (pdatabase revealed higher overall and individual complication rates and higher data granularity. The nationwide database may underestimate complications of patients with adult cervical deformity (ACD) particularly in regard to perioperative surgical details owing to coding and deformity generalizations.

    Study Design Retrospective analysis of nationwide Veterans Health Administration (VA) clinical and administrative data. Objective Examine the association between HIV infection and the rate of spine surgery for degenerative spine disease. Summary of Background Data Combination anti-retroviral therapy (cART) has prolonged survival in patients with HIV/AIDS, increasing the prevalence of chronic conditions such as degenerative spine disease that may require spine surgery. Methods We studied all HIV infected patients under care in the VA from 1996–2008 (n=40,038) and uninfected comparator patients (n=79,039) matched on age, gender, race, year, and geographic region. The primary outcome was spine surgery for degenerative spine disease defined by ICD-9 procedure and diagnosis codes. We used a multivariate Poisson regression to model spine surgery rates by HIV infection status, adjusting for factors that might affect suitability for surgery (demographics, year, comorbidities, body mass index, cART, and laboratory values). Results Two-hundred twenty eight HIV infected and 784 uninfected patients underwent spine surgery for degenerative spine disease during 700,731 patient-years of follow-up (1.44 surgeries per 1,000 patient-years). The most common procedures were spinal decompression (50%), and decompression and fusion (33%); the most common surgical sites were the lumbosacral (50%), and cervical (40%) spine. Adjusted rates of surgery were lower for HIV infected patients (0.86 per 1,000 patient-years of follow-up) than for uninfected patients (1.41 per 1,000 patient-years; IRR 0.61, 95% CI: 0.51, 0.74, Pdegenerative spine disease. Possible explanations include disease prevalence, emphasis on treatment of non-spine HIV-related symptoms, surgical referral patterns, impact of HIV on surgery risk-benefit ratio, patient preferences, and surgeon bias.

    We had previously established concentrated autologous bone marrow aspirate transplantation (CABMAT), a one-step, low-invasive, joint-preserving surgical technique for treating osteonecrosis of the femoral head (ONFH). The present study aimed to evaluate the effects of CABMAT as a hip preserving surgical approach, preventing femoral head collapse in asymptomatic ONFH. In total, 222 patients (341 hips) with ONFH were treated with CABMAT between April 2003 and March 2013. Based on magnetic resonance imaging, we determined that 119 of these patients had bilateral asymptomatic ONFH (238 hips), and 38 further patients had unilateral asymptomatic ONFH (38 hips). In this series, we retrospectively examined 31 hips in 31 patients with unilateral asymptomatic ONFH treated surgically between 2003 and 2012 and followed up for more than 2 years. Clinical and radiological evaluation were performed immediately before the procedure and at the final follow-up. The two-year follow-up rate among patients with unilateral ONFH was 82% (31/38). Therefore, the present study included 31 patients (19 males and 12 females), with a mean age and follow-up period of 40 and 5.8 years, respectively. Of the 31 asymptomatic hips, 5, 6, 10, and 10 had osteonecrosis of types A, B, C1, and C2, respectively. The diagnosis, classification, and staging of ONFH were based on the 2001 Japanese Orthopaedic Association (JOA) classification. Secondary collapse of the femoral head was observed in 6/10 hips and 5/10 hips with osteonecrosis of types C1 and C2, respectively. Total hip arthroplasty was performed in 9.6% of patients (3/31 hips), at an average of 33 months after surgery. Clinical symptoms improved after surgery, and the secondary collapse rate at a mean of 5.8 years after CABMAT was lower than that reported in several previous studies on the natural course of asymptomatic ONFH. Early diagnosis of ONFH (i.e., before femoral head collapse) and early intervention with CABMAT could improve the

    Full Text Available Abstract Background 18F-FDG PET/CT is widely utilized in the management of cancer patients. The aim of this paper was to comprehensively describe the specific methodology utilized in our single-institution cumulative retrospective experience with a multimodal imaging and detection approach to 18F-FDG-directed surgery for known/suspected malignancies. Methods From June 2005-June 2010, 145 patients were injected with 18F-FDG in anticipation of surgical exploration, biopsy, and possible resection of known/suspected malignancy. Each patient underwent one or more of the following: (1 same-day preoperative patient diagnostic PET/CT imaging, (2 intraoperative gamma probe assessment, (3 clinical PET/CT specimen scanning of whole surgically resected specimens (WSRS, research designated tissues (RDT, and/or sectioned research designated tissues (SRDT, (4 micro PET/CT specimen scanning of WSRS, RDT, and/or SRDT, (5 total radioactivity counting of each SRDT piece by an automatic gamma well counter, and (6 same-day postoperative patient diagnostic PET/CT imaging. Results Same-day 18F-FDG injection dose was 15.1 (± 3.5, 4.6-26.1 mCi. Fifty-five same-day preoperative patient diagnostic PET/CT scans were performed. One hundred forty-two patients were taken to surgery. Three of the same-day preoperative patient diagnostic PET/CT scans led to the cancellation of the anticipated surgical procedure. One hundred forty-one cases utilized intraoperative gamma probe assessment. Sixty-two same-day postoperative patient diagnostic PET/CT scans were performed. WSRS, RDT, and SRDT were scanned by clinical PET/CT imaging and micro PET/CT imaging in 109 and 32 cases, 33 and 22 cases, and 49 and 26 cases, respectively. Time from 18F-FDG injection to same-day preoperative patient diagnostic PET/CT scan, intraoperative gamma probe assessment, and same-day postoperative patient diagnostic PET/CT scan were 73 (± 9, 53-114, 286 (± 93, 176-532, and 516 (± 134, 178-853 minutes

    The quality of water in 1 421 drinking-water wells was monitored in a nationwide well water study. Samples were taken once from all wells, and during three seasons from 421 wells. The wells were selected in such a way that me sample would be as representative as possible of the quality of the drinking-water in households' own wells in rural areas. The study comprised general water quality parameters, influence of sampling season, and factors related to the type, the condition and the pollution of the wells. In part of the well waters selenium, radioactivity and pesticides were determined. The effect of plumbing materials on the quality of water was also examined. (33 refs., 148 figs., 71 tabs.)

    OBJECTIVE Pedicle screw-based dynamic spinal stabilization systems (PDSs) were devised to decrease, theoretically, the risk of long-term complications such as adjacent-segment degeneration (ASD) after lumbar fusion surgery. However, to date, there have been few studies that fully proved that a PDS can reduce the risk of ASD. The purpose of this study was to examine whether a PDS can influence the incidence of ASD and to discuss the surgical coping strategy for L5-S1 segmental spondylosis with preexisting L4-5 degeneration with no related symptoms or signs. METHODS This study retrospectively compared 62 cases of L5-S1 segmental spondylosis in patients who underwent posterior lumbar interbody fusion (n = 31) or K-Rod dynamic stabilization (n = 31) with a minimum of 4 years' follow-up. The authors measured the intervertebral heights and spinopelvic parameters on standing lateral radiographs and evaluated preexisting ASD on preoperative MR images using the modified Pfirrmann grading system. Radiographic ASD was evaluated according to the results of radiography during follow-up. RESULTS All 62 patients achieved remission of their neurological symptoms without surgical complications. The Kaplan-Meier curve and Cox proportional-hazards model showed no statistically significant differences between the 2 surgical groups in the incidence of radiographic ASD (p > 0.05). In contrast, the incidence of radiographic ASD was 8.75 times (95% CI 1.955-39.140; p = 0.005) higher in the patients with a preoperative modified Pfirrmann grade higher than 3 than it was in patients with a modified Pfirrmann grade of 3 or lower. In addition, no statistical significance was found for other risk factors such as age, sex, and spinopelvic parameters. CONCLUSIONS Pedicle screw-based dynamic spinal stabilization systems were not found to be superior to posterior lumbar interbody fusion in preventing radiographic ASD (L4-5) during the midterm follow-up. Preexisting ASD with a modified Pfirrmann

    The risk of metachronous colorectal cancer is high after surgical resection for first colon cancer in Lynch syndrome. This study aimed to examine whether extended surgery decreases the risk of subsequent colorectal cancer and improves long-term survival. This was a retrospective study. Data were collected from a nationwide registry. Two hundred forty-two Lynch syndrome pathogenic variant carriers who underwent surgery for a first colon cancer from 1984 to 2009 were included. Patients underwent standard segmental colectomy (n = 144) or extended colectomy (n = 98) for colon cancer. Patients were followed a median of 14.6 up to 25 years. Risk of subsequent colorectal cancer in either group, overall and disease-specific survival, and operative mortality were the primary outcomes measured. Subtotal colectomy decreased the risk of subsequent colorectal cancer (HR, 0.20; 95% CI, 0.08-0.52; p = 0.001), compared with segmental resection. Subsequent colorectal cancer decreased in MLH1 carriers. The MSH2 carriers showed no statistical difference, possibly because of their small number. Disease-specific and overall survival within 25 years did not differ between the standard and extended surgeries (82.7% vs 87.2%, p = 0.76 and 47.2% vs 41.4%, p = 0.83). The cumulative risk of subsequent colorectal cancer was 20% in 10 years and 47% within 25 years after standard resection and 4% and 9% after extended surgery. The cumulative risk of metachronous colorectal cancer was 7% within 25 years after subtotal colectomy with ileosigmoidal anastomosis. One patient died of postoperative septicemia within 30 days after segmental colectomy. Data on surgical procedures were primarily collected retrospectively. Lynch syndrome pathogenic variant carriers may undergo subtotal colectomy to manage first colon cancer and avoid repetitive abdominal surgery and to reduce the remaining bowel to facilitate easier endoscopic surveillance. It provides no survival benefit, compared with segmental colon

    Anastomotic leak has a negative impact on the prognosis of patients who undergo colorectal cancer resection. However, data on anastomotic leak are limited for stage IV colorectal cancers. The purpose of this study was to investigate the impact of anastomotic leak on survival and the decision to administer chemotherapy and/or metastasectomy after elective surgery for stage IV colorectal cancer. This was a nationwide, retrospective cohort study. Data were obtained from the Danish Colorectal Cancer Group, the Danish Pathology Registry, and the National Patient Registry. Patients who were diagnosed with stage IV colorectal cancer between 2009 and 2013 and underwent elective resection of their primary tumors were included. The primary outcome was all-cause mortality depending on the occurrence of anastomotic leak. Secondary outcomes were the administration of and time to adjuvant chemotherapy, metastasectomy rate, and risk factors for leak. Of the 774 patients with stage IV colorectal cancer who were included, 71 (9.2%) developed anastomotic leaks. Anastomotic leak had a significant impact on the long-term survival of patients with colon cancer (p = 0.04) but not on those with rectal cancer (p = 0.91). Anastomotic leak was followed by the decreased administration of adjuvant chemotherapy in patients with colon cancer (p = 0.007) but not in patients with rectal cancer (p = 0.47). Finally, anastomotic leak had a detrimental impact on metastasectomy rates after colon cancer but not on resection rates of rectal cancer. Retrospective data on the selection criteria for primary tumor resection and metastatic tumor load were unavailable. The impact of anastomotic leak on patients differed between stage IV colon and rectal cancers. Survival and eligibility to receive chemotherapy and metastasectomy differed between patients with colon and rectal cancers. When planning for primary tumor resection, these factors should be considered.

    Current knowledge of the impact of facial vascularized composite allograft (VCA) procurement on the transplantation outcomes of the concomitantly recovered solid organs is limited to isolated case reports and short-term results. Here we report on a nationwide analysis of facial allograft donor surgery experience and long-term outcomes of the concomitantly recovered solid organs and their recipients. There were 10 facial VCA procurements in organ donors between December 2008 and October 2014. We identified the population of subjects who received solid organs from these 10 donors using the Scientific Registry of Transplant Recipients. We retrospectively reviewed operative characteristics, intraoperative parameters, and postoperative outcomes. Six of 10 donor surgeries were performed at outside institutions, all on brain-dead donors. Mean operative duration for facial VCA recovery was 6.9 hours (range, 4-13.25 hours). A total of 36 solid organs were recovered and transplanted into 35 recipients. Survival rates for kidney and liver recipients were 100% and 90% at a median follow-up of 33 and 27.5 months, respectively (range, 6-72 months). Graft survival rates for kidneys and livers were 15 of 16 (94%) and 9 of 10 (90%), respectively. Recipient and graft survival rates for hearts and lungs were 75% (n = 4) and 100% (n = 3) at mean follow-up time of 14.75 and 16 months, respectively. A liver recipient died at 22 months from unknown causes and a heart recipient died of leukemia at 10 months. Facial VCA procurement does not appear to adversely affect the outcomes of transplant recipients of concomitantly recovered solid organ allografts.

    The prevalence of obesity and number of patients undergoing bariatric surgery are increasing. Obesity has adverse effects in patients with acute pancreatitis (AP). We investigated whether bariatric surgery affects outcomes of patients with AP. We performed a retrospective study, collecting data from the US Nationwide Inpatient Sample (2007-2011) on all adult inpatients (≥18 years) with a principal diagnosis of AP (n = 1,342,681). We compared primary clinical outcomes (mortality, acute kidney injury, and respiratory failure) and secondary outcomes related to healthcare resources (hospital stay and charges) among patient groups using univariate and multivariate analyses. We performed a propensity score-matched analysis to compare outcomes of patients with versus without bariatric surgery. Of patients admitted to the hospital with a principal diagnosis of AP, 14,332 (1.07%) had undergone bariatric surgery. The number of patients that underwent bariatric surgery doubled, from 1801 in 2007 to 3928 in 2011 (P < .001). AP in patients that had undergone bariatric surgery was most frequently associated with gallstones. Multivariate analysis associated prior bariatric surgery with decreased mortality (odds ratio, 0.41; 95% confidence interval, 0.18-0.92), shorter duration of hospitalization (0.65 days shorter; P < .001), and lower hospital charges ($3558 lower) than in patients with AP not receiving bariatric surgery (P < .001). A propensity score-matched cohort analysis found that mortality and odds of acute kidney injury were similar between patients with versus without history of bariatric surgery, whereas respiratory failure was less frequent in patients who received bariatric surgery (1.34% vs 4.42%; P < .001). Prior bariatric surgery in patients hospitalized with AP is not adversely associated with in-hospital mortality, development of organ failure, or healthcare resource use. Bariatric surgery may mitigate the obesity-associated adverse prognostication in AP

    Marfan syndrome is associated with morbidity and mortality due to aortic dilatation and dissection. Preventive aortic root replacement has been the standard treatment in Marfan syndrome patients with aortic dilatation. In this study, we present aortic event data from a nationwide Marfan syndrome cohort. The nationwide cohort of Danish Marfan syndrome patients was established from the Danish National Patient Registry and the Cause of Death Register, where we retrieved information about aortic surgery and dissections. We associated aortic events with age, sex, and Marfan syndrome diagnosis prior or after the first aortic event. From the total cohort of 412 patients, 150 (36.4 %) had an aortic event. Fifty percent were event free at age 49.6. Eighty patients (53.3 %) had prophylactic surgery and seventy patients (46.7 %) a dissection. The yearly event rate was 0.02 events/year/patient in the period 1994-2014. Male patients had a significant higher risk of an aortic event at a younger age with a hazard ratio of 1.75 (CI 1.26-2.42, p = 0.001) compared with women. Fifty-three patients (12.9 %) were diagnosed with MFS after their first aortic event which primarily was aortic dissection [n = 44 (83.0 %)]. More than a third of MFS patients experienced an aortic event and male patients had significantly more aortic events than females. More than half of the total number of dissections was in patients undiagnosed with MFS at the time of their event. This emphasizes that diagnosing MFS is lifesaving and improves mortality risk by reducing the risk of aorta dissection.

    Full Text Available Objective. To report the patient demographics and nonsurgical complementary and alternative medicine treatment used at a Korean medicine hospital for low back pain (LBP and/or sciatica after surgery. Methods. Medical records of patients who visited a spine-specialized Korean medicine hospital at 2 separate sites for continuous or recurrent LBP or sciatica following back surgery were reviewed. The demographics, MRI and/or CT scans, and treatments were assessed. Results. Of the total 707 patients, 62% were male and the average age was 50.20 years. Ninety percent of patients presented with LBP and 67% with sciatica. Eighty-four percent were diagnosed with herniated nucleus pulposus at time of surgery. Of these patients, 70% had pain recurrence 6 months or later, but 19% experienced no relief or immediate aggravation of pain after surgery. Many patients selected traditional Korean medicine treatment as primary means of postsurgery care (47%. When time to pain recurrence was short or pain persisted after surgery, return of symptoms at the same disc level and side was frequent. Conclusion. An integrative treatment model focusing on Korean medicine and used in conjunction with radiological diagnostics and conventional medicine is currently used as a treatment option for patients with pain after lumbar spine surgery.

    Opiate addiction remains intractable in a large percentage of patients, and relapse is the biggest hurdle to recovery because of psychological dependence. Multiple studies identify a central role of the nucleus accumbens (NAc) in addiction; several studies note decreased addictive behavior after interventions in this area. Based on animal experiments, our institute started the clinical trial for the treatment of drug addicts' psychological dependence by making lesions in the bilateral NAc with stereotactic surgery from July 2000. The short-term outcomes were encouraging and triggered rapid application of this treatment in China from 2003 to 2004. However, lack of long-term outcomes and controversy eventually led to halting the surgery for addiction by the Ministry of Health of China in November 2004 and a nationwide survey about it later. Our institute had performed this surgery in 272 patients with severe heroin addiction. The follow-up study showed that the 5-year nonrelapse rate was 58% and the quality of life was significantly improved. Patients had several kinds of side effects, but the incidence rate was relatively low. The patients gradually recovered more than 5 years after the surgery. The side effects did not severely influence an individual's life or work. Nationwide surgery showed that the nonrelapse rate was 50% in the sample of 150 cases, from 1167 patients overall who underwent stereotactic surgery in China. Although sometimes accompanied by neuropsychological adverse events, stereotactic ablation of NAc may effectively treat opiate addiction. Lesion location has a significant impact on treatment efficacy and requires further study. Because ablation is irreversible, the NAc surgery for addiction should be performed with cautiousness, and deep brain stimulation (DBS) is an ideal alternative. Copyright © 2013 Elsevier Inc.

    Objective To characterize current vestibular schwannoma (VS) surgery outcomes with a nationwide database and identify factors associated with increased complications and prolonged hospital course. Study Design Retrospective review utilizing the University HealthSystem Consortium national inpatient database. Setting US academic health centers. Subjects and Methods Data from patients undergoing VS surgery were analyzed over a 3-year time span (October 2012 to September 2015). Surgical outcomes, such as length of stay (LOS), complications, and mortality, were analyzed on the basis of race, sex, age, and comorbidities during the 30-day postoperative period. Results A total of 3697 VS surgical cases were identified. The overall mortality rate was 0.38%, and the overall complication rate was 5.3%. Advanced age significantly affected intensive care unit LOS, mortality, and complications ( P = .04). Comorbidities, including hypertension, obesity, and depression, also significantly increased complication rates ( P = .02). Sixty-eight patients (1.8%) had a history of irradiation, and they had a significantly increased LOS ( P = .03). Conclusion Modern VS surgery has a low mortality rate and a relatively low rate of complications. Several factors contribute to high complication rates, including age and comorbidities. These data will help providers in counseling patients on which treatment course might be best suited for them.

    Work-hour regulations for residency programmes in Switzerland, including a 50-hour weekly limit, were set in on 1 January 2005. Patient safety was one of the major arguments for the implementation. As the effect of the restriction of residency work hours on patient care in Switzerland has not yet been evaluated on objective data, the aim of the present study was to assess its impact by comparing the patients' morbidity and mortality before (2001-2004) and after (2005-2008) the implementation. Retrospective analysis of records of the Spitalzentrum Biel AG, a large referral center classified according to the Swiss Medical Association, collected in the database of the Association for Quality Assurance in Surgery (AQC), a prospective database of consecutive patients undergoing surgical procedures in Switzerland. A selection of 2,686 patients with common surgeries, operated on by residents, was performed. There were 1,259 (46.9%) patients meeting our inclusion criteria who were admitted during the period before introduction of work-hour limitation and 1,427 (53.1%) patients after introduction. The in-hospital mortality and postoperative surgical complication rate were significantly higher after the reform (p limitation implemented in Switzerland was not associated with surgical patient safety measure improvement for common surgeries (i.e., morbidity and mortality rate). Further research on a nationwide basis is needed to assess the value of the higher surgical complication and mortality rate.

    Integrated 6-year cardiothoracic surgical residency programs have recently been implemented in the United States. We report the results of the first published nationwide survey assessing the motivations, satisfaction, and ambitions of integrated 6-year residents. A 63-question web-based survey was distributed to 83 residents enrolled in 21 Accreditation Council for Graduate Medical Education-accredited integrated 6-year programs in November 2013. There was an outstanding 69% response rate. The median age of integrated 6-year residents was 29 years with women comprising 24%. A clear majority had faculty mentorship (95%) and significant clinical exposure in medical school. Focused (100%) and abbreviated (74%) training curricula were identified as the top advantages of integrated 6-year programs; the format itself was a significant factor (46%) in career choice. Most integrated 6-year residents (95%) were satisfied with their program; 80.7% were satisfied with their operative experience thus far. Career plans skewed toward adult cardiac surgery (67%), followed by pediatric cardiac (24%) and general thoracic (9%) surgery; 49% were not particularly concerned about future employment, with 65% foreseeing an increase in opportunities. Specialized training (eg, aortic, heart failure, minimally invasive, congenital) was anticipated by 77%. Most integrated 6-year residents envision an academic career (94.7%). This survey takes an important snapshot of the nascent integrated 6-year format. Mentorship and intense clinical exposure are critical in attracting applicants. Purported advantages of the format are holding true among integrated 6-year residents, with the majority satisfied with their programs. These early data indicate that this format holds significant promise in attracting and retaining highly qualified trainees to academic cardiothoracic surgery.

    The use of obesity surgery has increased during the past decade. There is a need for population-based assessments of causes and risk factors for postoperative mortality. The objective of this study was to assess causes and risk factors for 1-year mortality after obesity surgery. This nationwide retrospective population-based cohort study included essentially all obesity surgery patients in Sweden from 1980-2010. Data were collected from Swedish national registries and medical records. Patient characteristics, co-morbidities, and surgical procedures were assessed in relation to 1-year mortality through multivariable Cox proportional hazards regression, providing hazard ratios (HR), and 95% confidence intervals (CI) adjusted for age, sex, surgical procedure, surgical access, and co-morbidity. Among 22,487 obesity surgery patients the 1-year cumulative mortality was .38% (n = 85). Follow-up of cohort was complete. Median time of postoperative death was 45 days. Main causes of death included cardiopulmonary complications (myocardial infarction [n = 14; 16%], pulmonary embolism [n = 12; 14%], sudden cardiac arrest [n = 11; 13%]), and anastomotic leak (n = 12; 14%). Male sex (HR = 2.31; 95% CI 1.48-3.60), diabetes (HR = 2.47; 95% CI 1.44-4.23), and congestive heart failure (HR = 4.82; 95% CI 2.25-10.35) were independently associated with increased 1-year mortality, while age, hypertension, cerebrovascular disease, coronary heart disease, chronic obstructive pulmonary disease, asthma, and surgical procedure were not. Open surgery entailed an increased mortality compared to laparoscopic surgery from 2000-2010 (HR = 2.72; 95% CI 1.53-4.83), but not from 1990-1999 (HR = .39; 95% CI .11-1.32). Although the absolute risk of mortality is low, the increased relative risk of mortality associated with male sex, diabetes, congestive heart failure, and open surgical access could influence clinical decision making.

    GNE myopathy is a slowly progressive autosomal recessive myopathy caused by mutations in the GNE (glucosamine (UDP-N-acetyl)-2-epimerase/N-acetylmannosamine kinase) gene. This study aimed to (1) develop a nationwide patient registry for GNE myopathy in order to facilitate the planning of clinical trials and recruitment of candidates, and (2) gain further insight into the disease for the purpose of improving therapy and care. Medical records of genetically-confirmed patients with GNE myopathy at the National Center Hospital of the National Center of Neurology and Psychiatry (NCNP) were retrospectively reviewed in order to obtain data reflecting the severity and progression of the disease. We also referred to items in the datasheet of the nationwide registry of dystrophinopathy patients in the Registry of Muscular Dystrophies (Remudy). Items selected for the registration sheet included age, sex, age at onset, past history and complications, family history, body weight and height, pathological findings of muscle biopsy, grip power, walking ability, respiratory function, cardiac function, willingness to join upcoming clinical trials, and participation in patient associations. A copy of the original genetic analysis report was required of each patient. We successfully established the Remudy-GNE myopathy. Currently, 121 patients are registered nationwide, and 93 physicians from 73 hospitals collaborated to establish the registry. The mean age at onset was 27.7 ± 9.6 years, and 19.8% (24/121) of patients could walk without assistance. Mean presumed durations from onset to use of assistive devices (cane and/or braces) and a wheelchair, and loss of ambulation were 12.4, 15.2, and 21.1 years, respectively. Three patients had a past history and/or complication of idiopathic thrombocytopenia. To share the progress of this study with the community, newsletters were published on a regular basis, and included information regarding new phase I clinical trials for GNE

    Bariatric surgery has a lot of problems in anesthesia. We retrospectively compared anesthesia for bariatric surgery in yellow race with that in normal weight patients. Twenty patients who received bariatric surgery and 20 normal body weight patients who received abdominal surgery in Japan were enrolled. Induction condition, depth of epidural space, dose of anesthetics, duration of the effects of muscle relaxants, ventilation, and fluid management in bariatric surgery were analyzed and compared with those in normal body weight patients. An epidural catheterization was successful under ultrasound guide in the bariatric group. The depth epidural space was significantly larger in the bariatric group. Cormack and Lehane classification and the number of intubation attempt were not different between the two groups, while one bariatric case was once awakened to intubate blindly. Pressure-controlled ventilation was used in the bariatric group. Four bariatric patients were continuously ventilated after surgery. The doses of anesthetics and fluid infusion rate were not different between the two groups when calculated by ideal body weight in the bariatric group. The duration of the effects of rocuronium and pancuronium were shorter in the bariatric group. For anesthesia of yellow race patients undergoing bariatric surgery, intravenous anesthetics and acetate Ringer's solution with 1% glucose could be administered per ideal body weight, the effects of muscle relaxants lasted shorter, pressure-controlled ventilation could keep oxygenation with adequate carbon dioxide, and ultrasound assist was useful in epidural catheterization in the bariatric patients.

    Cantillano, Pablo; Rubio, Fabián; Naser, Alfredo; Nazar, Rodolfo

    Endoscopic sinonasal surgery is the procedure of choice in the treatment of chronic rhinosinusitis and sinonasal polyposis refractory to medical treatment, with high rates of success (76% to 97.5%). However, 2.5%-24% of those patients will require revision surgery (RESS). In this study, we present the clinical, anatomical, radiological and histological features of patients receiving RESS in our centre during a 3-year period. A retrospective review of clinical, anatomical, radiological and histopathological data of patients receiving revision endoscopic sinonasal surgery between 2012 and 2014 was carried out. From 299 surgery procedures performed, 27 (9%) were revision surgeries. The mean patient age was 46 years, with a male/female ratio of 1.4/1. The most frequent preoperative and postoperative diagnosis was chronic polypoid rhinosinusitis. The mean time since the previous surgery was 6.1 years, with 11.9 months of mean follow-up since that surgery. Stenotic antrostomy was found during revision in 81.5% of the patients and incomplete anterior ethmoidectomy and persistent uncinate process, in 59.3%. In radiology, 70.4% of patients had persistent anterior ethmoidal cells. Antrostomy or widening of antrostomy was performed in 96.3% of cases and anterior ethmoidectomy or completion of it was performed in 66.7%. Polyps, stenotic antrostomy and incomplete ethmoidectomy were the most frequent causes of revision surgery, in concordance with the procedures performed. The patients had long periods of time without follow-up between surgeries. Further investigation is necessary to generate measures to reduce the number of revision surgeries.

    The goal of this study was to examine the effect of clinical depression, posttraumatic stress disorder, and comorbid depression and posttraumatic stress disorder on in-hospital mortality after a coronary artery bypass grafting surgery. It is hypothesized that depression, posttraumatic stress disorder, and comorbid depression and posttraumatic stress disorder will independently contribute to an increased risk for in-hospital mortality rates after coronary artery bypass grafting surgery. We performed a retrospective analysis of the 2006 Nationwide Inpatient Sample database. The Nationwide Inpatient Sample database provides information on approximately 8 million US inpatient stays from about 1000 hospitals. We performed chi(2) and unpaired t tests to evaluate potential confounding group demographic and medical variables. Hierarchic logistic regression was used with forced order entry of depression, posttraumatic stress disorder, and comorbid depression and posttraumatic stress disorder. Deceased patients were more likely to have had depression (alive, 24.8%; deceased, 60.3%; P posttraumatic stress disorder (alive, 13.4%; deceased, 56.1%; P posttraumatic stress disorder (alive, 7.8%; deceased, 48.5%; P posttraumatic stress disorder (odds ratio, 2.09; 95% confidence interval, 1.65-2.64), and comorbid depression and posttraumatic stress disorder (odds ratio, 4.66; 95% confidence interval, 3.46-6.26) had an increased likelihood of in-hospital mortality compared with that seen in patients who were alive. Two findings were noteworthy. First, depression, posttraumatic stress disorder, and comorbid depression and posttraumatic stress disorder are prevalent in patients undergoing coronary artery bypass grafting procedures. Second, depression, posttraumatic stress disorder, and comorbid depression and posttraumatic stress disorder increase the risk of death by magnitudes comparable with well-established physical health risk factors after coronary artery bypass grafting surgery

    To evaluate the incidence of secondary primary malignancy (SPM) in patients with ovarian cancer using a nationwide retrospective population-based dataset. Patients newly diagnosed with ovarian cancer between 1997 and 2010 were identified using Taiwan's National Health Insurance database. Patients with antecedent malignancies were excluded. Standardized incidence ratios (SIRs) for SPM were calculated and compared with the cancer incidence in the general population. Risk factors for cancer development were analyzed using Cox proportional hazard models. Effects of surgery, chemotherapy, and radiotherapy after ovarian cancer diagnosis were regarded as time-dependent variables to prevent immortal time bias. During the 14-year study period (follow-up of 56,214 person-years), 707 cancers developed in 12,127 patients with ovarian cancer. The SIR for all cancers was 2.78 (95% confidence interval 2.58-3.00). SIRs for follow-up periods of >5, 1-5, and cancer diagnosis, SIRs were significantly higher for cancers of the colon, rectum, and anus (2.14); lung and mediastinum (1.58); breast (1.68); cervix (1.65); uterus (7.96); bladder (3.17), and thyroid (2.23); as well as for leukemia (3.98) and others (3.83). Multivariate analysis showed that age ≥ 50 years was a significant SPM risk factor (hazard ratio [HR] 1.60). Different treatments for ovarian cancer, including radiotherapy (HR 2.07) and chemotherapy (HR 1.27), had different impacts on SPM risk. Patients with ovarian cancer are at increased risk of SPM development. Age ≥ 50 years, radiotherapy, and chemotherapy are independent risk factors. Close surveillance of patients at high risk should be considered for the early detection of SPM.

    Oral glucose-lowering medications are associated with excess risk of heart failure (HF). Given the absence of comparative data among drug classes, we performed a retrospective study in 32 Health Services of 16 Italian regions accounting for a population of 18 million individuals, to assess the association between HF risk and use of sulphonylureas, DPP-4i, and glitazones. We extracted data on patients with type 2 diabetes who initiated treatment with DPP-4i, thiazolidinediones, or sulphonylureas alone or in combination with metformin during an accrual time of 2 years. The endpoint was hospitalization for HF (HHF) occurring after the first 6 months of therapy, and the observation was extended for up to 4 years. A total of 127 555 patients were included, of whom 14.3% were on DPP-4i, 72.5% on sulphonylurea, 13.2% on thiazolidinediones, with average 70.7% being on metformin as combination therapy. Patients in the three groups differed significantly for baseline characteristics: age, sex, Charlson index, concurrent medications, and previous cardiovascular events. During an average 2.6-year follow-up, after adjusting for measured confounders, use of DPP-4i was associated with a reduced risk of HHF compared with sulphonylureas [hazard ratio (HR) 0.78; 95% confidence interval (CI) 0.62-0.97; P = 0.026]. After propensity matching, the analysis was restricted to 39 465 patients, and the use of DPP-4i was still associated with a lower risk of HHF (HR 0.70; 95% CI 0.52-0.94; P = 0.018). In a very large observational study, the use of DPP-4i was associated with a reduced risk of HHF when compared with sulphonylureas. Published on behalf of the European Society of Cardiology.

    Bladder dysfunction in patients with spina bifida can lead to significant morbidity due to renal insufficiency. Indications for surgery vary among institutions and the impact is unclear. We examined trends and variations in urological interventions and chronic renal insufficiency in patients with spina bifida. We reviewed NIS (Nationwide Inpatient Sample) for all patients with spina bifida treated from 1998 to 2011. We used ICD-9-CM codes to identify urological surgery and chronic renal insufficiency. We calculated the Spearman correlation coefficients between rates of spina bifida related bladder surgeries and rates of chronic renal insufficiency outcomes by state. Linear regression models were fitted to investigate the associations between rates of spina bifida related surgery and chronic renal insufficiency across treatment years. We identified 427,616 spina bifida hospital admissions. Mean patient age was 26 years and 56% of patients were female. Of the admissions 35,249 (8%) were for chronic renal insufficiency and 11,078 (3%) were for surgery. During the study period chronic renal insufficiency rates doubled from 6% to 12% and surgery rates decreased from 2.0% to 1.8%. There was a moderately weak inverse association between surgery and chronic renal insufficiency rates with time (r = -0.3, p = 0.06) and by state (r = -0.3, p = 0.04). On multivariate analysis higher rates of surgery were associated with the state in which the patient was treated (p spina bifida related surgery (p = 0.67). We observed a temporal and geographic trend toward decreasing urological surgery and increasing chronic renal insufficiency rates in spina bifida and a wide variation in urological surgical rates among states. Further study is needed to determine the factors behind these trends and variations in spina bifida management. Copyright © 2016 American Urological Association Education and Research, Inc.

    Previous studies suggest that long-term mortality is increased in patients who undergo splenectomy during surgery for colorectal cancer. The reason for this association remains unclear. The purpose of this study was to investigate the association between inadvertent splenectomy attributed to iatrogenic lesion to the spleen during colorectal cancer resections and long-term mortality in a national cohort of unselected patients. This was a retrospective, nationwide cohort study. Data were collected from the database of the Danish Colorectal Cancer Group and merged with data from the National Patient Registry and the National Pathology Databank. Danish patients with colorectal cancer undergoing curatively intended resection between 2001 and 2011 were included in the study. The primary outcome was long-term mortality for patients surviving 30 days after surgery. Secondary outcomes were 30-day mortality and risk factors for inadvertent splenectomy. Multivariable and propensity-score matched Cox regression analyses were used to adjust for potential confounding. In total, 23,727 patients were included, of which 277 (1.2%) underwent inadvertent splenectomy. There was no association between inadvertent splenectomy and long-term mortality (adjusted HR = 1.15 (95% CI, 0.95-1.40); p = 0.16) in the propensity score-matched model, whereas 30-day mortality was significantly increased (adjusted HR = 2.31 (95% CI, 1.71-3.11); p splenectomy was most often seen during left hemicolectomy (left hemicolectomy vs right hemicolectomy: OR = 24.76 (95% CI, 15.30-40.06); p splenectomy during resection for colorectal cancer does not seem to increase long-term mortality. The previously reported reduced overall survival after inadvertent splenectomy may be explained by excess mortality in the immediate postoperative period.

    Many insurance companies have considerable prebariatric surgery requirements despite a lack of evidence for improved clinical outcomes. The hypothesis of this study is that insurance-specific requirements will be associated with a decreased progression to surgery and increased delay in time to surgery. Retrospective data collection was performed for patients undergoing bariatric surgery evaluation from 2010-2015. Patients who underwent surgery (SGY; n = 827; mean body mass index [BMI] 49.1) were compared with those who did not (no-SGY; n = 648; mean BMI: 49.4). Univariate and multivariate analysis were performed to identify specific co-morbidity and insurance specific predictors of surgical dropout and time to surgery. A total of 1475 patients using 12 major insurance payors were included. Univariate analysis found insurance requirements associated with surgical drop out included longer median diet duration (no-SGY = 6 mo; SGY = 3 mo; Psurgery dropout. Additionally, surgical patients had an average interval between initial visit and surgery of 5.8±4.6 months with significant weight gain (2.1 kg, Psurgery insurance requirements were associated with lack of patient progression to surgery in this study. In addition, delays in surgery were associated with preoperative weight gain. Although prospective and multicenter studies are needed, these findings have major policy implications suggesting insurance requirements may need to be reconsidered to improve medical care.

CONCLUSIONES: Los conocimientos de la fisiopatología, de la senilidad y los avanzos en el manoseo del trauma quirúrgico están permitiendo extender los recursos de la cirugía cardíaca en el grupo de pacientes más edosos. La elección de la técnica anestésica debe tener criterio, bien como la hidratación, la asistencia ventilatoria y la analgesia pos-operatoria, permitiendo reducción de la morbimortalidad en este grupo de mayor riesgo quirúrgico.BACKGROUND AND OBJECTIVES: Increased life expectancy makes increasingly older patients to be submitted to cardiac surgeries. This study aimed at evaluating the incidence of octogenarian patients submitted to cardiac surgeries in the Heart Institute, Hospital das Clínicas, FMUSP, in the last 16 years. METHODS: The number of myocardial revascularization (MR and valvar surgeries (VS was analyzed for the period 1986 to 2001 and, within each group, the number of surgeries in octogenarian patients. Data were descriptively analyzed. RESULTS: Data have shown a progressive increase in the number of octogenarian patients submitted to cardiac surgeries. Myocardial revascularization surgeries have increased from 0.13% in 1986 to 3.5% in 2001. Valvar surgeries have increased from 0% in 1986 to 1.44% in 2001, with the highest rate of 3.02% in 1999. CONCLUSIONS: The understanding of pathophysiology and senility, and the advances in surgical trauma handling are allowing cardiac surgery resources to be expanded to elderly patients. Anesthetic technique should be carefully chosen, as well as hydration, ventilatory assistance and postoperative analgesia, to provide

    BACKGROUND: The mortality associated with anastomotic leakage (AL) after colonic cancer surgery is high and management often results in permanent fecal diversion. Preservation of bowel continuity in combination with proximal loop diversion (salvage) may reduce the number of permanent ostomies...... without jeopardizing safety. STUDY DESIGN: This nationwide study used prospective data from the database of the Danish Colorectal Cancer Group, the National Patient Registry, and patient files. Patients with AL requiring surgery (grade C) were categorized according to the type of surgical treatment....... Takedown and salvage were undertaken in 433 (85.4%) and 74 (14.6%) patients, respectively. Salvage was performed more frequently for Hinchey I-II or minor anastomotic defects and resulted in increased likelihood of stoma reversal (adjusted hazard ratio 3.24, 95% CI 2.04 to 5.16, p

    Female Genital Plastic Surgery, a relatively new entry in the field of Cosmetic and Plastic Surgery, has promised sexual enhancement and functional and cosmetic improvement for women. Are the vulvovaginal aesthetic procedures of Labiaplasty, Vaginoplasty/Perineoplasty ("Vaginal Rejuvenation") and Clitoral Hood Reduction effective, and do they deliver on that promise? For what reason do women seek these procedures? What complications are evident, and what effects are noted regarding sexual function for women and their partners? Who should be performing these procedures, what training should they have, and what are the ethical considerations? This study was designed to produce objective, utilizable outcome data regarding FGPS. 1) Reasons for considering surgery from both patient's and physician's perspective; 2) Pre-operative sexual functioning per procedure; 3) Overall patient satisfaction per procedure; 4) Effect of procedure on patient's sexual enjoyment, per procedure; 5) Patient's perception of effect on her partner's sexual enjoyment, per procedure; 6) Complications. This cross-sectional study, including 258 women and encompassing 341 separate procedures, comes from a group of twelve gynecologists, gynecologic urologists and plastic surgeons from ten centers in eight states nationwide. 104 labiaplasties, 24 clitoral hood reductions, 49 combined labiaplasty/clitoral hood reductions, 47 vaginoplasties and/or perineoplasties, and 34 combined labiaplasty and/or reduction of the clitoral hood plus vaginoplasty/perineoplasty procedures were studied retrospectively, analyzing both patient's and physician's perception of surgical rationale, pre-operative sexual function and several outcome criteria. Combining the three groups, 91.6% of patients were satisfied with the results of their surgery after a 6-42 month follow-up. Significant subjective enhancement in sexual functioning for both women and their sexual partners was noted (p = 0.0078), especially in patients

    The positive prognostic value of HPV-infections in oropharyngeal squamous cell cancer (OSCC) patients has led to the initiation of prospective clinical trials testing the value of treatment de-escalation. It is unclear how to define patients potentially benefiting from de-escalated treatment, whether a positive smoking history impacts survival data and what kind of de-escalation might be best. Here, we investigate the effect of HPV-status, smoking habit and treatment design on overall survival (OS) and progression free survival (PFS) of 126 patients with tonsillar SCC (TSCC) who underwent CO 2 -laser-surgery and risk adapted adjuvant treatment. HPV-DNA-, HPV-mRNA-, and p16 INK4A -expression were analysed and results were correlated to OS and PFS. Factors tested for prognostic value included HPV-status, p16 INK4A -protein expression, therapy and smoking habit. Log rank test and p-values ≤0.05 defined significant differences between groups. The highest accuracy of data with highest significance in this study is given when the HPV-RNA-status is considered. Using p16 INK4A -expression alone or in combination with HPV-DNA-status, would have misclassified 23 and 7 patients, respectively. Smoking fully abrogates the positive impact of HPV-infection in TSCC on survival. Non-smoking HPV-positive TSCC patients show 10-year OS of 100% and 90.9% PFS when treated with adjuvant RCT. The presented data show that high-precision HPV-detection methods are needed, specifically when treatment decisions are based on the results. Furthermore, smoking habit should be included in all studies and clinical trials testing HPV-associated survival. Adjuvant RCT especially for HPV-positive non-smokers may help to avoid distant failure. Copyright © 2017 Elsevier B.V. All rights reserved.

    2009-06-01

    Robotic surgery has evolved from an investigational surgical approach to a clinically useful adjunct in multiple surgical specialties over the past decade. Advocates of robotic-assisted gynecologic surgery revere the system's wristed instrumentation, ergonomic positioning, and three-dimensional high-definition vision system as significant improvements over laparoscopic equipment's four degrees of freedom and two-dimensional laparoscope that demand the surgeon stand throughout a procedure. The cost, lack of haptic feedback, and the bulky size of the equipment make robotics less attractive to others. Studies evaluating outcomes in robotic-assisted gynecologic surgery are limited. Multiple small retrospective studies demonstrate the safety and feasibility of robotic hysterectomy. With increased surgeon experience, operative times are similar to, or shorter than, laparoscopic cases. Robotic assistance can facilitate suturing in laparoscopic myomectomies, and is associated with decreased blood loss and a shorter hospital stay, although may require longer operative times. Robotic assistance has also been applied to multiple procedures in the subspecialties of infertility, urogynecology and gynecologic oncology with good success and relatively low morbidity. However, further research is warranted to better evaluate the relative benefits and costs of robotic assisted gynecologic surgery.

    Intrauterine adhesions (IUA) are a problematic complication after abortion, but their incidence is unknown. Our objective was to assess the incidence of IUA following induced abortion and the risk factors for IUA. Retrospective cohort study. A nationwide registry study. All women undergoing induced abortion (n = 80 015) in Finland between 2000 and 2008. The data were retrieved from the Finnish Abortion Registry and the Hospital Discharge Registry. The diagnosis of IUA or complications was based on the diagnostic codes (ICD-10) and operative codes according to the NOMESCO Classification of Surgical Procedures (NCSP). IUA were defined as ICD-10 code N85.6 or operative code LCG02. A sub-analysis of IUA cases and five matched controls was performed. The incidence of and risk factors for IUA. A total of 12 (1.5 per 10 000) IUA diagnoses were identified from 79 960 eligible induced abortions. The rate of IUA was 1.5 and 2.0 cases per 10 000 abortions following medically and surgically induced abortion, respectively (P = 0.19). In a subgroup analysis of IUA cases and five matched controls, surgical treatment of the remaining products of conception following abortion significantly increased the risk of IUA [odds ratio 5.50 (95% CI 1.46-20.79; P = 0.012)]. IUA that require further treatment are rare after induced abortion. Surgical evacuation following medical or surgical abortion was a risk factor for diagnosis of IUA. These results suggest that trauma to a recently pregnant uterus is an important risk factor for IUA. This article is protected by copyright. All rights reserved.

    2008-01-01

    The number of trauma victims in Turkey is expected to increase as a consequence of the increasing vehicular traffic, potential for earthquakes, and risk of terrorist attacks. The Turkish Association for Trauma and Emergency Surgery monitors trauma cases, publishes a quarterly journal, organizes trauma courses and seminars for various health personnel nationwide. It is also extending efforts to improve in-hospital care by establishing trauma and emergency surgery fellowships and trauma and emergency surgery centers nationwide, which is run by General Surgeons currently. Turkey faces the same dilemma as the rest of the developed world regarding the future of trauma surgeons in the current era of nonoperative trauma management. We suggest that the field of trauma and emergency surgery be redefined to include emergency general surgery and cavitary trauma.

    The purpose of this study is to compare outcomes of patients who become pregnant within the first year after surgery and those who delayed pregnancy until after 1 year after surgery. A retrospective review was performed to identify patients who became pregnant after their gastric-bypass surgery from 2001 to 2004. Endpoints included pregnancy complications, fetal birth weight and outcome, delivery method, weight change during pregnancy, and nutrition. Of 2,423 patients who had undergone bariatric surgery from 2001 to 2004, 21 patients became pregnant within the first year after surgery and 13 became pregnant after 1 year. Similar outcomes were seen between the 2 groups regarding fetal weight, term pregnancy, and complications. Pregnancy outcomes within the first year after weight-loss surgery revealed no significant episodes of malnutrition, adverse fetal outcomes, or pregnancy complications. Anxiety over poor outcomes of pregnancy during the first year after bariatric surgery can be allayed.

    To investigate outcomes and predictors of in-hospital morbidity and mortality after total pancreatectomy (TP) and islet autotransplantation. The nationwide inpatient sample (NIS) database was used to identify patients who underwent TP and islet autotransplantation (IAT) between 2002-2012 in the United States. Variables of interest were inherent variables of NIS database which included demographic data (age, sex, and race), comorbidities (such as diabetes mellitus, hypertension, and deficiency anemia), and admission type (elective vs non-elective). The primary endpoints were mortality and postoperative complications according to the ICD-9 diagnosis codes which were reported as the second to 25(th) diagnosis of patients in the database. Risk adjusted analysis was performed to investigate morbidity predictors. Multivariate regression analysis was used to identify predictors of in-hospital morbidity. We evaluated a total of 923 patients who underwent IAT after pancreatectomy during 2002-2012. Among them, there were 754 patients who had TP + IAT. The most common indication of surgery was chronic pancreatitis (86%) followed by acute pancreatitis (12%). The number of patients undergoing TP + IAT annually significantly increased during the 11 years of study from 53 cases in 2002 to 155 cases in 2012. Overall mortality and morbidity of patients were 0% and 57.8 %, respectively. Post-surgical hypoinsulinemia was reported in 42.3% of patients, indicating that 57.7% of patients were insulin independent during hospitalization. Predictors of in-hospital morbidity were obesity [adjusted odds ratio (AOR): 3.02, P = 0.01], fluid and electrolyte disorders (AOR: 2.71, P < 0.01), alcohol abuse (AOR: 2.63, P < 0.01), and weight loss (AOR: 2.43, P < 0.01). TP + IAT is a safe procedure with no mortality, acceptable morbidity, and achieved high rate of early insulin independence. Obesity is the most significant predictor of in-hospital morbidity.

    The number of bariatric procedures performed in Japan is increasing. There are isolated reports of bariatric surgery, but there have been no nationwide surveys including long-term data. We retrospectively reviewed data for patients who underwent bariatric and metabolic surgery throughout Japan and reviewed outcomes. Surveys were sent to ten institutions for number of procedures, preoperative patient weight and preoperative obesity-related comorbidities, and data at 1, 3, and 5 years postoperatively. Improvement of type 2 diabetes mellitus at 3 years after surgery was stratified by baseline ABCD score, based on age, body mass index, C-peptide level, and duration of diabetes. Replies were received from nine of the ten institutions. From August 2005 to June 2015, 831 patients, including 366 males and 465 females, underwent bariatric procedures. The mean age was 41 years, and mean BMI was 42 kg/m 2 . The most common procedure was laparoscopic sleeve gastrectomy (n = 501, 60 %) followed by laparoscopic sleeve gastrectomy with duodenojejunal bypass (n = 149, 18 %). Laparoscopic Roux-en-Y gastric bypass was performed in 100 patients (12 %), and laparoscopic adjustable gastric banding was performed in 81 (10 %). At 3 years postoperatively, the remission rate of obesity-related comorbidities was 78 % for diabetes, 60 % for hypertension, and 65 % for dyslipidemia. Patients with complete remission of diabetes at 3 years postoperatively had a higher ABCD score than those without (6.4 ± 1.6 vs 4.2 ± 2.0, P Bariatric and metabolic surgery for Japanese morbidly obese patients is safe and effective.

    Morbid obesity prevalence is reaching epidemic proportions in Western society. Long-term weight loss can be achieved by bariatric surgery. This surgery also has a positive impact in the reduction of obesity related co-morbid conditions. The purpose of this study is to determine the reasons that bariatric surgery patients had to visit the emergency department within a three month period after surgery. A retrospective chart review study was performed at the UPR Hospital in Carolina. Patients with the diagnosis of morbid obesity who had bariatric surgery were identified. Of the 283 patients who met the criteria, the following information was obtained: gender, age, height, weight, pre-operative BMI, obesity-related comorbid conditions, post operative length of stay (LOS), and reasons and length of stay of Emergency Department (ED) visits within a 3 month period after surgery. Statistical analysis was done with Statistical Package for Social Sciences (SPSS) Program. The same profile of gender and BMI was obtained between the population that had the surgery and the sample that visited the ED, the group of patients between 20-29 years old was more likely to visit the ED. No correlation was found between a longer post operative length of stay and an increased probability of visiting the ED. Of the population, 5% had to visit ED within a three month period. The most common post operative complications were: Abdominal Pain (46.2%), Emesis (38.5%), and Dehydration (30.8%). Other less frequent complications were nausea, DVT, pneumonia, dizziness, gastritis, infected wound and upper GI bleeding. The most common reasons that bariatric surgery patients had to visit the emergency department within a three month period after surgery were: abdominal pain, emesis, dehydration and nausea. These complications could most likely be attributed to patient poor compliance with diet, resulting in the classical symptoms of the dumping syndrome which is common in patients that have undergone

    Full Text Available INTRODUCTION: Different immunoglobulin manufacturing processes may influence its effectiveness for Kawasaki disease. However, nationwide studies with longitudinal follow-up are still lacking. The aim of this study was to evaluate the comparative effectiveness of immunoglobulin preparations from a nationwide perspective. MATERIALS AND METHODS: This is a nationwide retrospective cohort study with a new user design. Data came from the National Health Insurance Research Database of Taiwan. From 1997 to 2008, children under 2 years old who received immunoglobulin therapy for the first time under the main diagnosis of Kawasaki disease were enrolled. The manufacturing processes were divided into β-propiolactonation, acidification and those containing IgA. The endpoints were immunoglobulin non-responsiveness, acute aneurysm, prolonged use of anti-platelets or anti-coagulants, and recurrence. RESULTS: In total, 3830 children were enrolled. β-propiolactonation had a relative risk of 1.45 (95% CI 1.08~1.94 of immunoglobulin non-responsiveness, however, the relative risks for acidification and containing IgA were non-significant. For acute aneurysms, acidification had a relative risk of 1.49 (95% CI 1.17~1.90, however the relative risks for β-propiolactonation and containing IgA were non-significant. For prolonged use of anti-platelets or anti-coagulants, β-propiolactonation had a relative risk of 1.44 (95% CI 1.18~1.76, and acidification protected against them both with a relative risk of 0.82 (95% CI 0.69~0.97, whereas the relative risk for containing IgA was non-significant. For recurrence, all three factors were non-significant. CONCLUSIONS: The effectiveness of immunoglobulin may differ among different manufacturing processes. β-propiolactonation had a higher risk of treatment failure and prolonged use of anti-platelets or anti-coagulants. Acidification may increase the risk of acute coronary aneurysms.

    To assess the incidence of strabismus, relationship of strabismus with type and width of scleral buckle after scleral buckling surgery for retinal detachment. Retrospective analysis was done of 360 eyes of 344 patients treated for rhegmatogenous retinal detachment with scleral buckling surgery between January 2008 and January 2013. The mean age of patients was 38.45 ± 18.12 years (range: 7 to 89 years). Strabismus was detected in 48 out of 344 (13.95%) patients at 6 weeks after scleral buckling surgery. Horizontal deviation was the commonest type. Incidence of strabismus was higher after repeat scleral buckling surgery (4/9, 44.4%) compared to patients who had single scleral buckling surgery (44/335, 13.1%) (P=0.02). Strabismus was observed in 18.5% of patients with implants, compared to 11.3% of patients who received explants (P=0.02). Strabismus surgery was performed on 2 (4.1%) cases. Horizontal strabismus is common after scleral buckling surgery for repair of retinal detachment. Repeat scleral buckling and use of implants resulted in a higher incidence of strabismus in the postoperative period. Majority of these cases resolve with conservative management.

    Retrospective database analysis. The impact of the 2008-2009 economic downtown on elective lumbar spine surgery is unknown. Our objective was to investigate the effect of the economic downturn on the overall trends of elective lumbar spine surgery in the United States. The Nationwide Inpatient Sample (NIS) was used in conjunction with US Census and macroeconomic data to determine historical trends. The economic downturn was defined as 2008 to 2009. Codes from the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM), were used in order to identify appropriate procedures. Confidence intervals were determined using subgroup analysis techniques. From 2003 to 2012, there was a 19.8% and 26.1% decrease in the number of lumbar discectomies and laminectomies, respectively. Over the same time period, there was a 56.4% increase in the number of lumbar spinal fusions. The trend of elective lumbar spine surgeries per 100 000 persons in the US population remained consistent from 2008 to 2009. The number of procedures decreased by 4.5% from 2010 to 2011, 7.6% from 2011 to 2012, and 3.1% from 2012 to 2013. The R 2 value between the number of surgeries and the S&P 500 Index was statistically significant ( P ≤ .05). The economic downturn did not affect elective lumbar fusions, which increased in total from 2003 to 2013. The relationship between the S&P 500 Index and surgical trends suggests that during recessions, individuals may utilize other means, such as insurance, to cover procedural costs and reduce out-of-pocket expenditures, accounting for no impact of the economic downturn on surgical trends. These findings can assist multiple stakeholders in better understanding the interconnectedness of macroeconomics, policy, and elective lumbar spine surgery trends.

    To examine in-hospital mortality and postoperative major complications in patients undergoing fusion surgery for atlantoaxial subluxation (AAS) and to examine whether the risk of perioperative complications varies between patients with and without rheumatoid arthritis (RA). A retrospective analysis of data from the Diagnosis Procedure Combination database, a nationwide administrative impatient database in Japan, identified 1090 patients who underwent spinal fusion surgery for AAS during 2007-2012. Patients' clinical characteristics were extracted, including age, sex, use of homologous blood transfusion, length of stay, and type of hospital. Clinical outcomes included in-hospital death and major complications, including surgical-site infection, sepsis, cardiac events, respiratory disorders, acute renal failure, pulmonary embolism, perioperative stroke, and vertebral injury. Massive blood transfusion was defined as at least 6 units of red blood cells. Four hundred sixty-five patients (42.7%) were classified as the RA group. In-hospital mortality after fusion surgery for AAS was 0.5% (5/1090), and major complications occurred in 5% (55/1090). Multivariate analyses showed that patients with RA were more likely to have major complications after surgery than patients without RA (odds ratio: 1.69; 95% confidence interval: 0.96-2.97; P = 0.07), and the rate of massive blood transfusion was significantly greater in patients with RA than in patients without RA (odds ratio: 2.29; 95% confidence interval: 1.12-4.68; P = 0.02). The in-hospital mortality after fusion surgery for AAS was relatively low. However, patients with RA had an increased risk of postoperative complications and massive blood transfusion compared with patients without RA. Copyright © 2015 Elsevier Inc. All rights reserved.

    Lifestyle interventions can substantially improve obesity and cardiometabolic risks. However, evidence of long-term benefits of national intervention is sparse. We aimed to evaluate the long-term effectiveness of a nationwide program for abdominal obesity. A retrospective cohort study was performed using a longitudinal nationwide individual data in subjects aged 40-74 years who underwent checkups in fiscal year (FY) 2008. Lifestyle interventions were provided via interview in subjects with abdominal obesity and at least one cardiometabolic risk factor. Subjects who attended the lifestyle intervention (participants) were compared to those who did not attend (non-participants). Outcomes were waist circumferences (WC) and body mass index (BMI) reduction, reversal of metabolic syndrome (MetS), and changes in cardiometabolic risks. We used a three-step process with robust analytic approaches to account for selection bias that included traditional multivariate analysis, propensity-score matching and instrumental variable (IV) analyses. Of 19,969,722 subjects, 4,370,042 were eligible for analyses; 111,779 participants and 907,909 non-participants. A higher percentage of participants had ≥5% reductions in obesity profiles at year 3, compared to non-participants (WC, 21.4% vs 16.1%; BMI, 17.6% vs 13.6%; pintervention for abdominal obesity, the at-risk population achieved significant reductions in WC, BMI, and cardiometabolic risks in 3 years. This study provides evidence that the nationwide program effectively achieved long-term improvement in abdominal obesity and cardiometabolic risks.

    Full Text Available Purpose. Hand infections are common, usually resulting from an untreated injury. In this retrospective study, we report on hand infection cases needing surgical drainage in order to assess patient demographics, causation of infection, clinical course, and clinical management.Methods. Medical records of patients presenting with hand infections, excluding post-surgical infections, treated with incision and debridement over a one-year period were reviewed. Patient demographics; past medical history; infection site(s and causation; intervals between onset of infection, hospital admission, surgical intervention and days of hospitalization; gram stains and cultures; choice of antibiotics; complications; and outcomes were reviewed.Results. Most infections were caused by laceration and the most common site of infection was the palm or dorsum of the hand. Mean length of hospitalization was 6 days. Methicillin-resistant Staphylococcus aureus, beta-hemolytic Streptococcus and methicillin-susceptible Staphylococcus aureus were the most commonly cultured microorganisms. Cephalosporins, clindamycin, amoxicillin/clavulanate, penicillin, vancomycin, and trimethoprim/sulfamethoxazole were major antibiotic choices. Amputations and contracture were the primary complications.Conclusions. Surgery along with medical management were key to treatment and most soft tissue infections resolved without further complications. With prompt and appropriate care, most hand infection patients can achieve full resolution of their infection.

    Abstract OBJECTIVE To review the management of bariatric surgical patients. QUALITY OF EVIDENCE MEDLINE, EMBASE, and Cochrane Library databases were searched, as well as PubMed US National Library, from January 1950 to December 2009. Evidence was levels I, II, and III. MAIN MESSAGE Bariatric surgery should be considered for obese patients at high risk of morbidity and mortality who have not achieved adequate weight loss with lifestyle and medical management and who are suffering from the complications of obesity. Bariatric surgery can result in substantial weight loss, resolution of comorbid conditions, and improved quality of life. The patient’s weight-loss history; his or her personal accountability, responsibility, and comprehension; and the acceptable level of risk must be taken into account. Complications include technical failure, bleeding, abdominal pain, nausea or vomiting, excess loose skin, bowel obstruction, ulcers, and anastomotic stricture. Lifelong monitoring by a multidisciplinary team is essential. CONCLUSION Limited long-term success of behavioural and pharmacologic therapies in severe obesity has led to renewed interest in bariatric surgery. Success with bariatric surgery is more likely when multidisciplinary care providers, in conjunction with primary care providers, assess, treat, monitor, and evaluate patients before and after surgery. Family physicians will play a critical role in counseling patients about bariatric surgery and will need to develop skills in managing these patients in the long-term. PMID:20841586

    National databases are being used with increasing frequency to conduct orthopaedic research. However, there are important differences in these databases, which could result in different answers to similar questions; this important potential limitation pertaining to database research in orthopaedic surgery has not been adequately explored. The purpose of this study was to explore the interdatabase reliability of two commonly used national databases, the Nationwide Inpatient Sample (NIS) and the National Surgical Quality Improvement Program (NSQIP), in terms of (1) demographics; (2) comorbidities; and (3) adverse events. In addition, using the NSQIP database, we identified (4) adverse events that had a higher prevalence after rather than before discharge, which has important implications for interpretation of studies conducted in the NIS. A retrospective cohort study of patients undergoing operative stabilization of transcervical and intertrochanteric hip fractures during 2009 to 2011 was performed in the NIS and NSQIP. Totals of 122,712 and 5021 patients were included from the NIS and NSQIP, respectively. Age, sex, fracture type, and lengths of stay were compared. Comorbidities common to both databases were compared in terms of more or less than twofold difference between the two databases. Similar comparisons were made for adverse events. Finally, adverse events that had a greater postdischarge prevalence were identified from the NSQIP database. Tests for statistical difference were thought to be of little value given the large sample size and the resulting fact that statistical differences would have been identified even for small, clinically inconsequential differences resulting from the associated high power. Because it is of greater clinical importance to focus on the magnitude of differences, the databases were compared by absolute differences. Demographics and hospital lengths of stay were not different between the two databases. In terms of comorbidities

    It is unclear whether dissemination of automated external defibrillators (AEDs) in public places can improve the rate of survival among patients who have had an out-of-hospital cardiac arrest. From January 1, 2005, through December 31, 2007, we conducted a prospective, population-based, observational study involving consecutive patients across Japan who had an out-of-hospital cardiac arrest and in whom resuscitation was attempted by emergency responders. We evaluated the effect of nationwide dissemination of public-access AEDs on the rate of survival after an out-of-hospital cardiac arrest. The primary outcome measure was the 1-month rate of survival with minimal neurologic impairment. A multivariate logistic-regression analysis was performed to assess factors associated with a good neurologic outcome. A total of 312,319 adults who had an out-of-hospital cardiac arrest were included in the study; 12,631 of these patients had ventricular fibrillation and had an arrest that was of cardiac origin and that was witnessed by bystanders. In 462 of these patients (3.7%), shocks were administered by laypersons with the use of public-access AEDs, and the proportion increased, from 1.2% to 6.2%, as the number of public-access AEDs increased (Ppublic-access AEDs, 31.6% were alive at 1 month with minimal neurologic impairment. Early defibrillation, regardless of the type of provider (bystander or emergency-medical-services personnel), was associated with a good neurologic outcome after a cardiac arrest with ventricular fibrillation (adjusted odds ratio per 1-minute increase in the time to administration of shock, 0.91; 95% confidence interval, 0.89 to 0.92; Ppublic-access AEDs increased from fewer than 1 per square kilometer of inhabited area to 4 or more. Nationwide dissemination of public-access AEDs in Japan resulted in earlier administration of shocks by laypersons and in an increase in the 1-month rate of survival with minimal neurologic impairment after an out

    . In an unselected nationwide cohort, we used multivariate Poisson regression models controlling for age, gender, comorbidity, concomitant medication, socio-economic data, and calendar year, to assess the risk of VTE associated with psoriasis. A total of 35,138 patients with mild and 3,526 patients with severe...... psoriasis were identified and compared with 4,126,075 controls. Patients with psoriasis had higher incidence rates per 1000 person-years of VTE than controls (1.29, 1.92, and 3.20 for controls, mild psoriasis, and severe psoriasis, respectively). The rate ratio (RR) of VTE was elevated in all patients...... with psoriasis with RR 1.35 (95% confidence interval [CI] 1.21–1.49) and RR 2.06 (CI 1.63–2.61) for mild and severe psoriasis, respectively. Exclusion of patients with malignancies, and censoring of patients undergoing surgery did not alter the results. Conclusion This nationwide cohort study indicates...

    2000-01-01

    A retrospective analysis of a consecutive series of 12 patients with 15 intracranial hemangiopericytomas treated at the University of Virginia using gamma surgery is presented. Clinical and radiographic follow up of 3 to 56 months is available for 10 patients with 12 tumors. There was one tumor present at the time of initial gamma surgery in each patient. Two new tumors occurred in patients previously treated. Nine of the tumors decreased in volume and three remained stable. Four of the nine tumors that shrank later progressed at an average of 22 months after treatment. Of the tumors that decreased in volume and have not progressed, the response has been for an average of 11 months. The follow-up for two tumors that remained unchanged was 10 and 34 months (average 22 months). A third tumor was unchanged at 42 months but the patient died of new disease adjacent to the treated area in the anterior skull base. There were no complications and the quality of life following the procedure was maintained or improved in every case. Gamma surgery is effective in palliating the patients by decreasing tumor volume and delaying recurrence. (author)

    To characterize nationwide variation and factors associated with clinical laboratories': (1) capabilities to send structured test results electronically to ordering practitioners' EHR systems; and (2) their levels of exchange activity, as measured by whether they sent more than three-quarters of their test results as structured data to ordering practitioners' EHR systems. A national survey of all independent and hospital laboratories was conducted in 2013. Using an analytic weighted sample of 9382 clinical laboratories, a series of logistic regression analyses were conducted to identify organizational and area characteristics associated with clinical laboratories' exchange capability and activity. Hospital-based clinical laboratories (71%) and larger clinical laboratories (80%) had significantly higher levels of capability compared to independent (58%) and smaller laboratories (48%), respectively; though all had similar levels of exchange activity, with 30% of clinical laboratories sending 75% or more of their test results electronically. In multivariate analyses, hospital and the largest laboratories had 1.87 and 4.40 higher odds, respectively, of possessing the capability to send results electronically compared to independent laboratories (pLaboratories located in areas with a higher share of potential exchange partners had a small but significantly greater capability to send results electronically and higher levels of exchange activity(pClinical laboratories' capability to exchange varied by size and type; however, all clinical laboratories had relatively low levels of exchange activity. The role of exchange partners potentially played a small but significant role in driving exchange capability and activity. Published by Elsevier B.V.

  9. Defensive medicine in Israel - a nationwide survey.

    Directory of Open Access Journals (Sweden)

    Elad Asher

    Full Text Available BACKGROUND: Defensive medicine is the practice of diagnostic or therapeutic measures conducted primarily as a safeguard against possible malpractice liability. We studied the extent, reasons, and characteristics of defensive medicine in the Israeli health care system. METHODS AND FINDINGS: Cross-sectional study performed in the Israeli health care system between April and July 2008 in a sample (7% of board certified physicians from eight medical disciplines (internal medicine, pediatrics, general surgery, family medicine, obstetrics and gynecology, orthopedic surgery, cardiology, and neurosurgery. A total of 889 physicians (7% of all Israeli board certified specialists completed the survey. The majority [60%, (95%CI 0.57-0.63] reported practicing defensive medicine; 40% (95%CI 0.37-0.43 consider every patient as a potential threat for a medical lawsuit; 25% (95%CI 0.22-0.28 have previously been sued at least once during their career. Independent predictors for practicing defensive medicine were surgical specialty [OR=1.6 (95%CI 1.2-2.2, p=0.0004], not performing a fellowship abroad [OR=1.5 (95%CI 1.1-2, p=0.027], and previous exposure to lawsuits [OR=2.4 (95%CI 1.7-3.4, p<0.0001]. Independent predictors for the risk of being sued during a physician's career were male gender [OR=1.6 (95%CI 1.1-2.2, p=0.012] and surgery specialty [OR=3.2 (95%CI 2.4-4.3, p<0.0001] (general surgery, obstetrics and gynecology, orthopedic surgery, and neurosurgery. CONCLUSIONS: Defensive medicine is very prevalent in daily physician practice in all medical disciplines. It exposes patients to complications due to unnecessary tests and procedures, affects quality of care and costs, and undermines doctor-patient relationships. Further studies are needed to understand how to minimize defensive medicine resulting from an increased malpractice liability market.

    Medical costs in the United States have been increasing disproportionally to gross domestic product, raising concerns about the sustainability of U.S. healthcare expenditures. Care of patients with thyroid disease has been identified as an area of medicine where cost increases have been pronounced. The goals of this study were to identify potential drivers of the cost of hospitalization following thyroid surgery, and to understand which of these factors may be contributing to observed increases in cost from 2003 to 2011. A retrospective cross-sectional analysis of discharge data from the Nationwide Inpatient Sample (NIS) database for all admissions following thyroid lobectomy or total thyroidectomy in the years 2003, 2007, and 2011 was performed. Multiple regression analysis via a weighted generalized linear model was used to identify factors that were independently associated with high cost of hospitalization. Trend as well as subgroup analyses were then performed to identify which of these factors could be contributing to increasing costs. There were 47,854 hospital admissions following total thyroidectomy or thyroid lobectomy identified in the years 2003, 2007, and 2011. The aggregate national cost of hospitalization increased from $198 million in 2003 to $373 million in 2011 in inflation-adjusted 2011 dollars. The weighted mean cost of hospitalization following thyroid surgery increased from $6154 to $8982 from 2003 to 2011 in inflation-adjusted 2011 dollars. Higher comorbidity score, total thyroidectomy, lymphadenectomy, western region, rural region, and certain postoperative complications were the factors most highly associated with increased hospital costs. Of these, an increasing proportion of patients with higher severity of illness score and an increasing proportion of patients undergoing total thyroidectomy and lymphadenectomy were implicated as the most likely contributors to the cost increases. The rate of total thyroidectomy and lymphadenectomy was

    Full Text Available Background: In almost six decades different surgical techniques have been developed to treat patients with morbid obesity. Various surgical techniques are generally divided with respect to their effect into restrictive, malabsorbtive and humoral and a combination of these. Surgically modified human metabolism ameliorates metabolic diseases, particularly diabetes, even in nonobese patients. The understanding of metabolic effects changed the traditional paradigm of bariatric surgery from simple weight-loss procedure to metabolic surgery affecting whole-body metabolism. Proper surgical technique for individual patient is the most important factor influencing long- term results, comorbidities and quality of life. Recommendations for patient selection, surgical methods and pre- and postoperative patient management are to be respected. Metabolic surgery principles and current concepts are presented.

    Paraquat poisoning associates very high mortality rate. Early treatment with hemoperfusion is strongly suggested by animal and human studies. Although the survival benefit of additional immunosuppressive treatment (IST) in combination with hemoperfusion is also reported since 1971, the large-scale randomized control trials to confirm the effects of IST is difficult to be executed. Therefore, we designed this nationwide large-scale population-based retrospective cohort study to investigate the outcome of paraquat poisoning with hemoperfusion and the additional effects of IST combined with hemoperfusion. This nationwide retrospective cohort study utilized data retrieved from the National Health Insurance Research Database (NHIRD) of Taiwan. A total of 1811 hospitalized patients with a diagnosis of paraquat poisoning who received hemoperfusion between 1997 and 2009 were enrolled. The mean age of all 1811 study subjects was 47.3 years. 70% was male. The overall survival rate was only 26.4%. Respiratory failure and renal failure were diagnosed in 56.2% and 36% patients. The average frequency of hemoperfusion was twice. IST was added in 42.2% patients. IST significantly increases survival rate (from 24.3% to 29.3%, Pparaquat-poisoned patients. The best survival effect of IST is the combination of methylprednisolone, cyclophosphamide and daily dexamethasone, especially in patients with younger age. PMID:24475310

    Increased risk of heart valve disease during treatment with certain dopamine agonists, such as cabergoline, has been observed in patients with Parkinson's disease. The same compound is used to treat hyperprolactinemia, but it is unknown whether this also associates with heart valve disease. The objective of the study was to assess the incidence of diagnosed heart valve disease and cardiac valve surgery among patients with hyperprolactinemia, compared with a general population cohort in Denmark. This was a nationwide, population-based, cohort study based on a nationwide hospital registry. We identified 2381 hyperprolactinemia patients with a first-time diagnosis recorded from 1994 through 2010 in the registry, with no previous hospital diagnosis of heart valve disease. Each patient was compared with 10 age- and gender-matched comparison cohort members from the general population. The association between hyperprolactinemia and heart valve disease was analyzed with Cox's proportional hazards regression, controlling for potential confounding factors. To assess the risk of cardiac valve surgery and avoid ascertainment bias, a subanalysis was made in a cohort of 2,387 hyperprolactinemia patients with no previous cardiac valve surgery and 23,870 comparison cohort members. Nineteen hyperprolactinemic patients (0.80%) were diagnosed with heart valve disease during a total of 17,759.8 yr of follow-up, compared with 75 persons (0.31%) in the comparison cohort during 179,940.6 yr of follow-up [adjusted hazard ratio 2.27 (95% confidence interval 1.35-3.82)]. Seven of the 10 patients treated with cabergoline and diagnosed with heart valve disease were asymptomatic and diagnosed on the basis of an echocardiography performed as a safety measure. However, only two patients with hyperprolactinemia (0.08%) underwent surgery, compared with 28 persons in the general population cohort (0.12%) [adjusted hazard ratio 0.55 (95% confidence interval 0.13-2.42)].

    The surgery during which the cochlear implant internal device is implanted is not entirely free of risks and may produce problems that will require revision surgeries. To verify the indications for cochlear implantation revision surgery for the cochlear implant internal device, its effectiveness and its correlation with certain variables related to language and hearing. A retrospective study of patients under 18 years submitted to cochlear implant Surgery from 2004 to 2015 in a public hospital in Brazil. Data collected were: age at the time of implantation, gender, etiology of the hearing loss, audiological and oral language characteristics of each patient before and after Cochlear Implant surgery and any need for surgical revision and the reason for it. Two hundred and sixty-five surgeries were performed in 236 patients. Eight patients received a bilateral cochlear implant and 10 patients required revision surgery. Thirty-two surgeries were necessary for these 10 children (1 bilateral cochlear implant), of which 21 were revision surgeries. In 2 children, cochlear implant removal was necessary, without reimplantation, one with cochlear malformation due to incomplete partition type I and another due to trauma. With respect to the cause for revision surgery, of the 8 children who were successfully reimplanted, four had cochlear calcification following meningitis, one followed trauma, one exhibited a facial nerve malformation, one experienced a failure of the cochlear implant internal device and one revision surgery was necessary because the electrode was twisted. The incidence of the cochlear implant revision surgery was 4.23%. The period following the revision surgeries revealed an improvement in the subject's hearing and language performance, indicating that these surgeries are valid in most cases.

    The impact of previous abdominal surgeries on the need for conversion to open surgery and on short-term outcomes during/after laparoscopic colectomy was retrospectively investigated. This retrospective cohort study was conducted from December 1996 through December 2009. This study was conducted at Osaka Medical College Hospital. A total of 1701 consecutive patients who had undergone laparoscopic resection of the colon and rectum were classified as not having previous abdominal surgery (n = 1121) or as having previous abdominal surgery (n = 580). Short-term outcomes were recorded, and risk factors for conversion to open surgery were analyzed. There were no significant differences in operative time, blood loss, number of lymph nodes removed, or conversion rate between the groups. The rate of inadvertent enterotomy was significantly higher in the previous abdominal surgery group than in the not having previous abdominal surgery group (0.9% versus 0.1%; p = 0.03), and the postoperative recovery time was significantly longer in the previous abdominal surgery group than in the not having previous abdominal surgery group. Ileus was more frequent in the previous abdominal surgery group than in the not having previous abdominal surgery group (3.8% versus 2.1%; p = 0.04). Significant risk factors for conversion to open surgery were T stage ≥3 (OR, 2.81; 95% CI, 1.89-3.75), median incision (OR, 4.34; 95% CI, 1.23-9.41), upper median incision (OR, 2.78; 95% CI, 1.29-5.42), lower median incision (OR, 1.82; 95% CI, 1.09-3.12), and transverse colectomy (OR, 1.76; 95% CI, 1.29-2.41). The incidence of successfully completed laparoscopic colectomy after previous abdominal surgery remains high, and the short-term outcomes are acceptable.

    Emergency general surgery (EGS) represents 11% of surgical admissions and 50% of surgical mortality in the United States. However, there is currently no established definition of the EGS procedures. To define a set of procedures accounting for at least 80% of the national burden of operative EGS. A retrospective review was conducted using data from the 2008-2011 National Inpatient Sample. Adults (age, ≥18 years) with primary EGS diagnoses consistent with the American Association for the Surgery of Trauma definition, admitted urgently or emergently, who underwent an operative procedure within 2 days of admission were included in the analyses. Procedures were ranked to account for national mortality and complication burden. Among ranked procedures, contributions to total EGS frequency, mortality, and hospital costs were assessed. The data query and analysis were performed between November 15, 2015, and February 16, 2016. Overall procedure frequency, in-hospital mortality, major complications, and inpatient costs calculated per 3-digit International Classification of Diseases, Ninth Revision, Clinical Modification procedure codes. The study identified 421 476 patient encounters associated with operative EGS, weighted to represent 2.1 million nationally over the 4-year study period. The overall mortality rate was 1.23% (95% CI, 1.18%-1.28%), the complication rate was 15.0% (95% CI, 14.6%-15.3%), and mean cost per admission was $13 241 (95% CI, $12 957-$13 525). After ranking the 35 procedure groups by contribution to EGS mortality and morbidity burden, a final set of 7 operative EGS procedures were identified, which collectively accounted for 80.0% of procedures, 80.3% of deaths, 78.9% of complications, and 80.2% of inpatient costs nationwide. These 7 procedures included partial colectomy, small-bowel resection, cholecystectomy, operative management of peptic ulcer disease, lysis of peritoneal adhesions, appendectomy, and laparotomy. Only 7 procedures account

    Obesity is a nationwide epidemic, and the only evidence-based, durable treatment of this disease is bariatric surgery. This field has evolved drastically during the past decade. One of the latest advances has been the increased use of robotics within this field. The goal of our study was to perform a systematic review of the recent data to determine the safety and efficacy of robotic bariatric surgery. The setting was the University Hospitals Case Medical Center (Cleveland, OH). A PubMed search was performed for robotic bariatric surgery from 2005 to 2011. The inclusion criteria were English language, original research, human, and bariatric surgical procedures. Perioperative data were then collected from each study and recorded. A total of 18 studies were included in our review. The results of our systematic review showed that bariatric surgery, when performed with the use of robotics, had similar or lower complication rates compared with traditional laparoscopy. Two studies showed shorter operative times using the robot for Roux-en-Y gastric bypass, but 4 studies showed longer operative times in the robotic arm. In addition, the learning curve appears to be shorter when robotic gastric bypass is compared with the traditional laparoscopic approach. Most investigators agreed that robotic laparoscopic surgery provides superior imaging and freedom of movement compared with traditional laparoscopy. The application of robotics appears to be a safe option within the realm of bariatric surgery. Prospective randomized trials comparing robotic and laparoscopic outcomes are needed to further define the role of robotics within the field of bariatric surgery. Longer follow-up times would also help elucidate any long-term outcomes differences with the use of robotics versus traditional laparoscopy.

    Use of bariatric surgery has increased dramatically during the past 10 years, particularly among women of reproductive age. To estimate bariatric surgery rates among women aged 18 to 45 years and to assess the published literature on pregnancy outcomes and fertility after surgery. Search of the Nationwide Inpatient Sample (1998-2005) and multiple electronic databases (Medline, EMBASE, Controlled Clinical Trials Register Database, and the Cochrane Database of Reviews of Effectiveness) to identify articles published between 1985 and February 2008 on bariatric surgery among women of reproductive age. Search terms included bariatric procedures, fertility, contraception, pregnancy, and nutritional deficiencies. Information was abstracted about study design, fertility, and nutritional, neonatal, and pregnancy outcomes after surgery. Of 260 screened articles, 75 were included. Women aged 18 to 45 years accounted for 49% of all patients undergoing bariatric surgery (>50,000 cases annually for the 3 most recent years). Three matched cohort studies showed lower maternal complication rates after bariatric surgery than in obese women without bariatric surgery, or rates approaching those of nonobese controls. In 1 matched cohort study that compared maternal complication rates in women after laparoscopic adjustable gastric band surgery with obese women without surgery, rates of gestational diabetes (0% vs 22.1%, P bariatric surgery group. Findings were supported by 13 other bariatric cohort studies.

    Bariatric surgery makes up an increasing percentage of general surgery training. The safety of resident involvement in these complex cases has been questioned. We evaluated patient outcomes in resident performed laparoscopic bariatric procedures. Retrospective review of patients undergoing a laparoscopic bariatric procedure over seven years at a tertiary care single center. Procedures were primarily performed by a general surgery resident and proctored by an attending surgeon. Primary outcomes included operative volume, operative time and leak rate with perioperative outcomes evaluated as secondary outcomes. A total of 1649 bariatric procedures were evaluated. Operations included laparoscopic bypass (690) and laparoscopic sleeve gastrectomy (959). Average operating time was 136 min. Eighteen leaks (0.67%) were identified. Graduating residents performed an average of 89 laparoscopic bariatric cases during their training. There were no significant differences between resident levels with concern to operative time or leak rate (p 0.97 and p = 0.54). General surgery residents can safely perform laparoscopic bariatric surgery. When proctored by a staff surgeon, a resident's level of training does not significantly impact leak rate.

    The rate of venous thromboembolic events (VTE) including deep venous thrombosis (DVT) and pulmonary embolism (PE) among women undergoing gynecologic surgery is high, particularly for women with a gynecologic malignancy. Current guidelines recommend VTE thrombopropylaxis in the immediate postoperative period for patients undergoing open surgery. However, the VTE prophylaxis recommendations for women undergoing minimally invasive gynecologic surgery are not as well established. The risk of VTE in patients undergoing minimally invasive surgery appears to be low based on retrospective analyses. To date, there are no established guidelines that specifically provide a standard of care for patients undergoing minimally invasive gynecologic surgery for benign or malignant disease.

    Biliary disease requiring intervention can be complicated in the postbariatric surgery patient. A retrospective review was completed to identify patients who underwent laparoscopic Roux-en-Y gastric bypass or laparoscopic sleeve gastrectomy from September 2001 to September 2014, and those who underwent biliary intervention were identified. A total of 1527 patients underwent bariatric surgery during the study period. Of the 1,112 patients without prior cholecystectomy, 91 (8%) had biliary symptoms requiring intervention. Ninety patients underwent cholecystectomy, with 86 successfully completed laparoscopically. Six patients required laparoscopy-assisted percutaneous transgastric endoscopic retrograde cholangiopancreatography along with cholecystectomy to clear gallstones from the common bile duct. Three patients who had undergone cholecystectomy before bariatric surgery developed primary common bile duct stones. Surgery for biliary disease after bariatric surgery can be completed successfully with minimal complications, and percutaneous transgastric endoscopic retrograde cholangiopancreatography has a high success rate of access to and clearance of the biliary tree.

  10. Redefining surgery for gastric cancer.

    Whiting, J. L.; Hallissey, M. T.; Rowlands, D. C.; Fielding, J. W. L.

    1999-12-01

    BACKGROUND: Despite encouraging retrospective and non-randomized trials, two large prospective, randomized trials of D1 vs D2 resections show double the mortality in the D2 group, with no increase in long-term survival. However, the D2 resection still offers the only hope of cure when N2 nodes are involved. We propose a reclassification of the International Union Against Cancer TNM "N" staging to a system with an anatomical basis that is useful in defining the surgery performed. Junctional nodes lying between the N1 and N2 tiers will act as a guide to surgery. Where these nodes are uninvolved, the probability of gastric bed (N2) involvement is low and the radical D2 dissection with its higher mortality and morbidity can be avoided.CONCLUSION: Such "stage-appropriate" surgery will reduce the number of D2 resections while ensuring that patients with N2 disease are not denied curative surgery. A prospective, randomized, controlled trial of targeted surgery is required.

    Reoperative bariatric surgery has become a common practice in many bariatric surgery programs. There is currently little evidence-based guidance regarding specific indications and outcomes for reoperative bariatric surgery. A task force was convened to review the current evidence regarding reoperative bariatric surgery. The aim of the review was to identify procedure-specific indications and outcomes for reoperative procedures. Literature search was conducted to identify studies reporting indications for and outcomes after reoperative bariatric surgery. Specifically, operations to treat complications, failed weight loss, and weight regain were evaluated. Abstract and manuscript reviews were completed by the task force members to identify, grade, and categorize relevant studies. A total of 819 articles were identified in the initial search. After review for inclusion criteria and data quality, 175 articles were included in the systematic review and analysis. The majority of published studies are single center retrospective reviews. The evidence supporting reoperative surgery for acute and chronic complications is described. The evidence regarding reoperative surgery for failed weight loss and weight regain generally demonstrates improved weight loss and co-morbidity reduction after reintervention. Procedure-specific outcomes are described. Complication rates are generally reported to be higher after reoperative surgery compared to primary surgery. The indications and outcomes for reoperative bariatric surgery are procedure-specific but the current evidence does support additional treatment for persistent obesity, co-morbid disease, and complications.

    Laparoscopic surgery for gastric cancer has become extremely widespread in recent years especially in Asian countries due to its low invasiveness. As to evidence of indication for laparoscopic surgery for gastric cancer, laparoscopic surgery for gastric cancer often appears to be indicated for early gastric cancer at many institutions, while evidence was considered to be insufficient to recommend laparoscopic surgery for gastric cancer at Stage II and above. There are also problems with indications for cases other than tumour factors. No meta-analyses and prospective studies have been reported, but outcomes of laparoscopic surgery for gastric cancer in gastric cancer patients with co-morbid and/or existing diseases have been reported in retrospective studies. Indications in the elderly appear to be favourable in terms of post-operative ambulation considering factors such as the degree of dissection in accordance with the status of the patient. Meta-analyses, randomized controlled trials and several retrospective studies have compared the short-term usefulness of laparoscopic surgery for gastric cancer with that of conventional gastrectomy. The superiority of laparoscopic surgery for gastric cancer has been reported in terms of the reduced amount of bleeding, a reduction in the administration frequency and period of analgesic doses, a reduction in the duration of fever, early recovery of intestinal movement and early return to oral intake. A small-scale randomized controlled trial and several retrospective studies have demonstrated no significant differences in survival rate, recurrence rate and type of recurrence between laparoscopic surgery for gastric cancer and conventional gastrectomy. The results of the aforementioned trials in early gastric cancer in Japan and Korea for which enrolment is complete remain to be published. © The Author 2016. Published by Oxford University Press.

  18. The retrospective gambler's fallacy

    Full Text Available The gambler's fallacy (Tune, 1964 refers to the belief that a streak is more likely to end than chance would dictate. In three studies, participants exhibited a extit{retrospective gambler's fallacy} (RGF in which an event that seems rare appears to come from a longer sequence than an event that seems more common. Study 1 demonstrates this bias for streaks, while Study 2 does so with single rare events and shows that the appearance of rarity is more important than actual rarity. Study 3 extends these findings from abstract gambling domains into real world domains to demonstrate the generalizability of the effects. The RGF follows from the law of small numbers (Tversky and Kahneman, 1971 and has many applications, from perceptions of the social world to philosophical debates about the existence of multiple universes.

    Obesity is a global epidemic affecting populations globally. Bariatric surgery is an effective treatment for morbid obesity, and has increased dramatically. Bariatric surgery candidates frequently have pre-existing nutritional deficiencies that might exacerbate post-surgery. To provide better health care management pre- and post-bariatric surgery, it is imperative to establish the nutritional status of prospective patients before surgery. The aim of this study was to assess and provide baseline data on the nutritional status of bariatric candidates. A retrospective study was conducted on obese patients who underwent bariatric surgery from 2008 to 2015. The medical records of 1538 patients were reviewed for this study. Pre-operatively, the most commonly observed vitamin deficiencies were Vitamin D (76%) and Vitamin B12 (16%). Anemia and iron status parameters were low in a considerable number of patients before surgery, as follows: hemoglobin 20%, mean corpuscular volume (MCV) 48%, ferritin 28%, serum iron 51%, and transferrin saturation 60%. Albumin and transferrin were found to be low in 10% and 9% of the patients, respectively, prior to surgery. In addition to deficiencies, a great number of patients had hypervitaminosis pre-operatively. Excess levels of Vitamin B6 (24%) was the most remarkable. The findings in this study advocate a close monitoring and tailored supplementation pre- and post-bariatric surgery. PMID:29324643

    In April of 1994, a vicious civil was erupted in Rwanda, with more than 500,000 people massacred by extremist militias. The second United Nations Assistance Mission in Rwanda (UNAMIR II) deployed in August 1994 to monitor the ceasefire, with an Australian Defence Force Contingent of Health Service Support consisting of staff for the UNAMIR Head-quarters, and the Australian Medical Support Force (AS MSF). A retrospective audit was conducted of all operative surgery performed during the year-long deployment, in the AS MSF operating theatres. Twenty surgeons rotated through in 6-week intervals. A total of 750 operations were performed on 547 patients, of which 636 (84.8%) involved civilians. A total of 558 (74.4%) cases were the result of trauma both accidental (38.4%) and war related (36%). The mean age of patients was 21.7 years. The age distribution was skewed, with 289 (38.5%) cases being performed on children. General surgeons performed a wide range of surgery, covering the majority of surgical specialties. These included cardiothoracic, neurosurgical, vascular and paediatric cases. Orthopaedic surgeons dealt with amputations, debridements and skin grafting in addition to bony injuries and infections. Children formed a substantial number of those treated, and required surgery for war-related injuries significantly more often than adults. Surgeons involved in future peacekeeping missions should be aware of the broad variety of clinical problems encountered, and undertake refresher training in the sub-specialties. Children are at great risk of violence in war, and if a civilization can be judged by the protection it affords its helpless, the Rwandan genocide and ensuing civil war represents a horrific example of the opposite extreme.

    The effect of precollegiate orthopaedic surgery on injury risk in the elite collegiate athlete is unknown. To (1) assess the relationship between precollegiate surgery and subsequent injury requiring surgery in National Collegiate Athletic Association (NCAA) Division I athletes at a single institution and (2) compare the risk of subsequent surgery in the ipsilateral versus contralateral extremity in those with a history of precollegiate surgery. Cohort study; Level of evidence, 3. A retrospective chart review was performed of all athletes who began participation from 2003 to 2009 until completion of eligibility. Athletes who received orthopaedic surgery in college were identified through the Sports Injury Monitoring System and were cross-referenced with medical records. The risk of orthopaedic surgery was evaluated using multivariate Cox and Poisson regression models, with sex and sport as additional covariates. Risk of subsequent surgery in the ipsila
