Filter by:Background. Gastric cancer is an important health care problem even though treatment advances, and it is diagnosed mainly in elderly. Surgery is the main treatment for gastric cancer and is associated with a high rate of postoperative complications and mortality, even higher in older patients. Chronological age seems not to be the main factor influencing the worse outcome of older patients, comorbidities and frailty have also been taken into account recently. Methods. Participation in the study will be offered to all centers that are currently part of the Spanish EURECCA (EUropean REgistry of Cancer CAre) Esophagogastric Cancer Registry. The impact of the frailty on different outcome variables will be evaluated. The main outcome variable will be 90-day mortality after the intervention. Health-Related Quality of Life (HRQoL) will also be evaluated. Objective. The objective of the study is to value the impact of frailty on gastric cancer surgery outcomes therein the Spanish EURECCA Esophagogastric Cancer Registry.
The aims of this study is to determine the inter- and intra-rater reliability of SEG and SEFS grade systems for postmastectomy lymphedema.
The Edmonton Obesity Staging System (EOSS) is a more comprehensive measure of obesity-related diseases and predictor of mortality than BMI or waist circumference. EOSS is also important in predicting post - operative outcome and 30-day mortality after metabolic surgery. The aim of this study is to determine whether EOSS could be an indicator for procedure selection in obesity and metabolic surgery.
Background: The list of studies with inconsistent data regarding the effect of intra-operative ventilatory management on post-operative lung injury is large. The literature is lacking data on the least injurious way of ventilating surgical patients intra-operatively. This study is necessary to support future guidelines on the practice of intra-operative mechanical ventilation. Specific Aim: The aims of this study is first to describe intra-operative ventilatory practices at the American University of Beirut Medical Center (AUBMC), (with particular focus on the mode of ventilation, tidal volume per body weight and PEEP settings) and second, to identify the post-operative complications that could be associated with particular settings. Methodology: This is a prospective observational study that will be conducted in the operating room at AUBMC, on patients being admitted for surgeries under general anesthesia. During the patient's stay in the hospital, targeted process (patient characteristics, surgical procedure, mechanical ventilation management, anesthesiologist characteristics) and outcomes parameters (postoperative pulmonary complications) will be collected for analysis. Patients will be monitored and followed up with intraoperatively and postoperatively. Analysis: Different parameters and outcomes will be collected and by subgrouping the patients per their medical history statistical significance will be tested to reach a correlative analysis to the outcomes documented. Statistical comparison will be made using the ANOVA, Student's t-test, and Chi-squared test. Level of statistical significance will be considered at p<0.05. Mean age, weight, height and BMI of participants in the different groups will be calculated. ANOVA test will be performed to test statistical significance to compare the different means between different subgroups. A two sided P value of less than 0.05 was considered to be significant Significance: The literature is lacking data on the least injurious way of ventilating surgical patients intra-operatively. This study is necessary to support future guidelines on the practice of intra-operative mechanical ventilation
Malnutrition has long been linked to postoperative complications and adverse outcomes in a variety of surgical fields , such as increased susceptibility to infection, delayed wound healing, and increased frequency of decubitus ulcers. In particular, it is a modifiable risk factor, as evident by studies that have associated optimization of preoperative nutrition with improved surgical outcomes. Therefore, it is important to identify these patients who are at risk so that appropriate nutritional support can be implemented. A range of options for nutritional status assessment have been proposed; a comprehensive assessment may include measurements of dietary intake, clinical assessment, anthropometric measurements, and biochemical measurements of serum protein, micronutrients and metabolic parameters . Many of the signs of malnutrition, however, only manifest in extreme cases. Thus it is crucial to identify sensitive markers that can be utilized to screen for clinical as well as subclinical malnutrition patients. In orthopaedic patients, the prevalence of clinical and subclinical malnutrition has been reported to be up to 42.4%. Common markers of malnutrition that have been studied include low serum albumin as a marker of protein status, low total lymphocyte count (TLC), and excessively high or low body mass index (BMI). They have been compared against various adverse surgical outcomes, including surgical site infections (SSI), delayed wound healing, unplanned intubation and ICU admission , postoperative anemia and cardiac complications , and length of hospital stay. However, conflicting results have been reported; for example, while hypoalbuminemia (serum albumin <3.5mg/dL) have been associated with increased risk of SSI and longer than average hospital stay, its effect on wound healing is less clear - Marin et al. reported no significant predictive value of hypoalbuminemia on wound healing, yet Greene et al. reported a 5-time increase in frequency of major wound complication. The purpose of this retrospective cohort study was to identify biomarkers of malnutrition in patients undergoing elective total knee arthroplasty (TKA) that are predictive of adverse in-hospital postoperative complications, which would facilitate the identification of at risk patients for nutritional optimization before surgery. Six-hundred and twenty-six patients who underwent elective TKA between 2013 and 2017 in the Prince of Wales Hospital in Hong Kong were reviewed; the preoperative serum albumin, TLC, and BMI were compared against in-hospital postoperative complications.
This retrospective, population-based cohort study will evaluate the comparative effectiveness of peripheral nerve blocks on patient outcomes after ambulatory shoulder surgery in adults patients undergoing surgery in Ontario.
This is a protocol for a trial carried out from 1999 to 2002. At that time, surgical patients received a large volume of intravenous saline during operations on the colon or the rectum, often so much fluid that their bodyweight increased by 4-6 kilograms. We hypothesized; that a restricted fluid regimen could prevent the development of cardiopulmonary complications and improve wound healing including the healing of an anastomosis of the gut. We designed a clinical randomized assessor blinded multi-center trial comparing a restricted fluid regimen to a standard fluid regimen, the difference being the volume of saline administered to the patients. Patients undergoing surgery on the colon or the rectum were included after informed oral and written consent. The restricted regimen aimed at zero-fluid balance with allowance for a body weight increase of 1 kg. The standard regimen was a bit "dryer" than the actual standard; our patients in the standard group received saline causing a body weight increase of only 3-4 kg. The fluid therapy started at midnight the day of operation, went on through the operation and continued on the wards until discharge. The patients were encouraged to eat and drink as much and as soon as possible after the operation. The primary outcome was the number of patients who died or suffered a complication measured within 30 days of surgery. We looked at all complications, but especially heart and lung complications and complications related to the healing of wounds and anastomosis. The patients was examined in the outpatient clinic after 30 days, and in addition, blinded assessors were reviewing the medical files for registration of postoperative complications. The results are published in The Annals of Surgery 2003; 238(5)641-48. The restricted regimen nearly halved the number of patients with complications, and heart and lung complications were almost eliminated. Other investigators confirmed the results, and a more restricted approach to fluid therapy to surgical patients has been implemented worldwide.
The aim of the present prospective study was, first, to verify the correlation between biliary colonization and postoperative infectious complications, and secondarily to asses morbidity and mortality for patients who underwent pancreaticoduodenectomy. The hypothesis is that a proportion of post-operative infections after pancreaticoduodenectomy is due to bacteria that colonize the bile ducts during the preoperative period.
Diastolic dysfunction is an important cause of hemodynamic instability in the perioperative field.Therefore this study aims to investigate the influence of existing diastolic dysfunction or deterioration of diastolic function on hemodynamic stability during induction of anesthesia and postoperative complications. The impact of different anesthetics on diastolic function is investigated.
A high percentage of patients undergoing major abdominal surgery will develop a postoperative complication. Our hypothesis is that by observing postoperative patients with continuous wireless monitoring, it is possible to detect the correlation between deviating vital parameters and subsequent postoperative complications. A prospective observational study will take place on general surgical wards with the enrolment of 500 patients in two different hospitals. Physiological parameters will be recorded for 96 hours postoperative. Data is collected preoperative, peroperative and postoperative in up to 6 months for data analyzing.
