Background: Surgical treatment of empyema thoracis in patients with chronic kidney disease is challenging, and few studies in the literature have evaluated this issue. In this study, we aim to report the surgical outcomes of empyema and to analyze factors predicting perioperative mortality in patients with chronic kidney disease. Methods: This retrospective study included data from 34 patients with chronic kidney disease (estimated glomerular filtration rate <60 mL/min/1.73 ㎡ for 3 or more months) who underwent surgery for empyema between 2012 and 2020. An analysis of demographic characteristics and perioperative variables, including complications, was carried out. Postoperative mortality was the primary outcome measure. Results: Patients' age ranged from 20 to 74 years with a 29-to-5 male-female ratio. The majority (n=19, 55.9%) of patients were in end-stage renal disease (ESRD) requiring maintenance hemodialysis. The mean operative time was 304 minutes and the mean intraoperative blood loss was 562 mL. Postoperative morbidity was observed in 70.5% of patients (n=24). In the subgroup analysis, higher values for operative time, blood loss, intensive care unit stay, and complications were found in ESRD patients. The mortality rate was 38.2% (n=13). In the univariate and multivariate analyses, poor performance status (Eastern Cooperative Oncology Group >2) (p=0.03), ESRD (p=0.02), and late referral (>8 weeks) (p<0.001) significantly affected mortality. Conclusion: ESRD, late referral, and poor functional status were poor prognostic factors predicting postoperative mortality. The decision of surgery should be cautiously assessed given the very high risk of perioperative morbidity and mortality in these patients.

Objective: To assess the effects of perioperative comprehensive supportive care interventions on outcome of Chinese esophageal cancer patients in a prospective study. Methods: 60 patients with primary esophageal carcinoma were randomized into an intervention group (IG, n=31) and a control group (CG, n=29). The Chinese version of symptom checklist-90 (SCL-90) was adopted to assess their psychological status. The interventions, including health education, psychological support, stress management, coping strategies and behavior training, were carried out in 3 phases (preoperative, postoperative I and postoperative II), and psychological effects were thereafter evaluated accordingly before surgery, and 1 week, 4 weeks and 24 weeks post-surgery. Medical costs were estimated at discharge. Survival of patients was estimated each year post-surgery. General health status and satisfaction-with-hospital were surveyed by a follow-up questionnaire 4 years post-surgery. Results: All the subjects demonstrated higher scores in the preoperative phase than the normal range of Chinese population concerning 7 psychological domains including somatization, obsessive-compulsive, depression, anxiety, hostility, phobic anxiety and paranoid ideation. Although no significant difference was observed between the two groups at admission, the scores of IG, which tended to decrease at a faster rate, were generally lower than those of CG at weeks 1, 4 and 24 post-surgery. The length of hospital stay and medical costs of IG were significantly less than those of CG and satisfaction-with-hospital was better. However, there was no significant difference in 4-year survival or health status between two groups. Conclusions: Appropriate perioperative comprehensive supportive care interventions help to improve the psychological state of Chinese patients with esophageal carcinoma, to reduce health care costs and to promote satisfaction of patients and their families with hospital.

This retrospective case-control study explored the factors associated with anaphylactic shock during surgery for cystic echinococcosis (CE) at the First Affiliated Hospital of Xinjiang Medical University between October 2008 and September 2013. Patients who suffered from anaphylactic shock (n=16) were age-matched 3:1 to patients who did not (n=43). Multivariate analysis suggested that IL-4 levels (odds ratio=1.096; 95% confidence interval=1.015-1.185; P=0.02) and cyst size (odds ratio=3.028, 95% confidence interval=1.259-7.283, P=0.013) were independently associated with CE-induced perioperative anaphylactic shock. Using the receiver operating characteristic (ROC) curves and a cut-off value of 415.7 ng/ml, IL-4 showed an area under the ROC (AUC) of 0.926, sensitivity of 75.0%, and specificity of 97.7%. Using a cut-off value of 7.8 cm, cyst size showed an AUC of 0.828, sensitivity of 81.3%, and specificity of 76.7%. In conclusion, results suggest that levels of IL-4 and cyst size were independently associated with echinococcosis-induced perioperative anaphylactic shock. These results could help identifying patients with echinococcosis at risk of anaphylactic shock in whom appropriate prophylaxis could be undertaken.

A total of 40 patients having a diagnosis of atherosclerotic coronary arterial disease were analysed on the operative outcomes according to variables as follows: 1) preoperative risk factors such as age, sex, CCS (Canadian Cardiovascular Society) functional class, type of angina, number of diseased vessel, presence of left main coronary artery stenosis, previous history of habitual smoking and presence of other medical diseases (diabetes mellitus, essential hypertension), 2) preoperative management such as intravenous infusion of nitroglycerine, preoperative IABP (intra-aortic balloon pump) support and whether the operation was scheduled as emergency or not, 3) intraoperative variables such as infusion method and composition of cardioplegic solutions, number of distal anastomosis, use of internal mammary artery, total cardiopulmonary bypass time and total cross clamp time. Complications included operative death in 12.5％, perioperative myocardial infarction in 25.0％ and perioperative arrhythmia in 17.5％. Nineteen perioperative variables were analyzed to identify risk factors for these end points. For operative death, presence of left main coronary artery stenosis (p = 0.056) and cardiopulmonary bypass time (p = 0.029) were significant in the univariate analysis, but presence of left main coronary artery lesion (p = 0.011, $\chi$$^2$= 6.45) and abscence of preoperative of IABP support (p = 0.069, $\chi$$^2$ = 3.30) were independent predictor in multivariate analysis (stepwise linear logistic regression).

Background: To determine surgical outcomes, perioperative complications, and patient outcomes in gynecologic cancer patients undergoing robotic surgery. Materials and Methods: Surgical outcomes, including docking time, total operative time, console time, estimated blood loss (EBL), conversion rate and perioperative complications were retrospectively reviewed in 30 gynecologic cancer patients undergoing robotic surgery. Patient outcomes included recovery time and patient satisfaction, as scored by a visual analogue scale (VAS) from 0-10. Results: The operations included 24 hysterectomies with pelvic lymphadenectomy (PLD) and/or para-aortic lymphadenectomy, four radical hysterectomies with PLD, and two radical trachelectomies with PLD. Mean docking time was $12.8{\pm}9.7min$, total operative time was $345.5{\pm}85.0min$, and console time was $281.9{\pm}78.6min$. These times were decreased in the second half of the cases. There was no conversion rate. Three intraoperative complications, including one external iliac artery injury, one bladder injury, and one massive bleeding requiring blood transfusion were reported. Postoperative complications occurred in eight patients, most were minor. Only one patient had port herniation that required reoperation. Mean hospital stay was $3.5{\pm}1.7days$, and recovery time was $14.2{\pm}8.1days$. Two-thirds of patients felt very satisfied and one-third felt satisfied; the mean satisfaction score was 9.4 +0.9. Two patients with stage III endometrial cancer developed isolated port site metastasis at five and 13 months postoperatively. Conclusions: Robotic surgery for gynecologic cancer appears to be feasible, with acceptable perioperative complication rate, fast recovery time and high patient satisfaction.

Several studies have reported a relation between serum levels of uric acid and a wide variety of cardiovascular conditions. But, the relationship between serum levels of uric acid and coronary artery disease (CAD) is still controversial. The present study was retrospectively designed to investigate whether CAD can be stratified by the level of uric acid and there are the relationships between preoperative levels of uric acid and perioperative biochemical markers in fifty-adult patients that underwent coronary artery bypass grafting surgery (CABG) and twenty-normal subjects. They were divided into the control, the unstable angina (UA-group) and the myocardial infarction group (MI-group). In preoperative levels of uric acid, the MI-group was higher than control and the UA-group. The MI-group had significantly higher correlations than the UA-group between preoperative levels of uric acid and left ventricular ejection fraction, cardiac markers (creatine kinase, lactate dehydrogenase and brain natriuretic peptide), renal markers (blood urea nitrogen and creatinine) or total leukocyte levels. At postoperative periods, the MI-group had higher relationships of uric acid with aspartate aminotransferase, blood urea nitrogen or creatinine levels. Although there was not statistically significant, the UA-group tended to have higher correlation coefficients than the MI-group between preoperative levels of uric acid and intensive care unit-stay (ICU), or postoperative mechanical ventilation time. These results reflect that increased levels of serum uric acid may be a tool for the diagnosis of coronary heart disease and may be considered as a good predictor in assessing the cardiac and renal functions in patients with myocardial infarction or unstable angina at the preoperative period. However, further studies should be performed in a large patient population.

Background: Conventionally, elderly hip fracture patients are assessed by orthopedists to decide whether they need geriatric intervention. We aimed to evaluate the effect of perioperative geriatric intervention on healthcare outcomes in patients undergoing surgery for hip fractures. Methods: Our care model for hip fracture surgery resembles a combination of a routine geriatric consultation model and a geriatric ward model. We retrospectively reviewed the medical records of patients aged ${\geq}65years$ undergoing surgery for hip fracture at a single tertiary hospital from January 2010 to December 2013. We assessed comorbidity, indwelling status, fracture type, and mode of anesthesia. We also evaluated in-hospital expenditure, duration of admission, disposition at discharge and 1-year mortality as clinical outcomes. We developed a propensity score model using the variables of age, cholesterol, and creatinine and examined the effect of perioperative geriatric intervention on intergroup differences of clinical variables. Results: Among 639 patients, 138 patients received the geriatric intervention and 501 patients received the usual care. Univariate analysis showed that factors such as age; Charlson comorbidity index; and serum levels of cholesterol, albumin, and creatinine differed significantly between these 2 groups. There was no significant difference between the groups in terms of 1-year mortality, disposition at discharge, and in-hospital expenditure in the propensity matched model. However, the duration of hospitalization was shorter in the intervention group ($8.9{\pm}0.8days$) than in the usual care group ($14.2{\pm}3.7days$, p=0.006). Conclusion: This care model of geriatric intervention for patients with hip fracture is associated with reduced hospitalization duration.

Purpose: To examine and compare the perioperative outcomes of laparoscopic adrenalectomy (LA) and to determine its efficacy in patients with nonfunctioning adrenal adenomas (NFA) and subclinical Cushing syndrome (SCS). Materials and Methods: We retrospectively analyzed the clinical data obtained from 79 consecutive patients who underwent LA for the treatment of either NFA (n=35) or SCS (n=44) between 2011 and 2016. All patients had undergone computed tomography, as well as endocrinological tests to confirm the diagnosis prior to the adrenalectomy. The primary endpoint was improved metabolic parameters relating to diabetes, hypertension, dyslipidemia, and obesity. Results: Patients with SCS compared to those with NFA showed a higher occurrence of diabetes (29.5% vs. 11.4%), hypertension (59.1% vs. 34.3%), and dyslipidemia (43.2% vs. 14.3%). Patients with SCS showed a smaller median tumor size compared to those with NFA (2.5 cm vs. 5 cm). No significant perioperative complications ${\geq}$ Clavien-Dindo classification grade III were observed in any patient (SCS or NFA group). In terms of their metabolic profile, patients with SCS showed a significant postoperative improvement in hypertension (50.0%), diabetes (53.9%), dyslipidemia (31.6%), and obesity (29.2%). However, patients with NFA showed a postoperative improvement only in dyslipidemia (40.0%) and obesity (4.8%). Conclusions: Owing to absence of significant perioperative complications and the marked postoperative improvement in metabolic impairment, LA is a useful treatment strategy in patients diagnosed with SCS. In contrast, LA was not observed to show beneficial effects in correcting/improving the metabolic profile in patients presenting with NFA.

Background Cleft treatment is frequently performed in Indonesia, mostly in charity missions, but without a postoperative protocol it is difficult to establish the risks and complications of cleft treatment. The present study was designed to give an overview of current cleft lip and palate treatment strategies in Indonesia and to assess the complication rates during and after surgery. Methods This prospective study evaluated anesthetic, intraoperative surgical, and short-term postoperative complications in patients undergoing primary, secondary, or corrective surgery for cleft lip and palate deformities. The population consisted of 98 non-syndromic cleft patients. The main anesthetic complication that occurred during general anesthesia was high blood pressure, whereas the main intraoperative surgical complication was excessive bleeding and the main early postoperative complication was extremely poor wound hygiene. Results In this study, there were no cases of perioperative or postoperative mortality. However, in 23 (23.4%) of the 98 operations performed, at least one perioperative complication related to anesthesia occurred. The intraoperative and early postoperative complications following cleft lip and/or palate were assessed. There was a significant difference in the complication rate between procedure types (χ²=0.02; P<0.05). However, no relationship was found between perioperative complications related to anesthesia and the occurrence of postoperative complications (χ²=1.00; P>0.05). Nonetheless, a significant difference was found between procedure types regarding perioperative complications and the occurrence of postoperative complications (χ²=0.031; P<0.05). Conclusions Further evaluation of these outcomes would help direct patient management toward decreasing the complication rate.

Objective: The perioperative management of antithrombotic therapy is often challenging and it requires a fine balance between the risk of hemorrhage and thrombosis. We aimed to evaluate the antithrombotic management for moderate to high risk patients in real world setting. Methods: Among the patients who were consulted to the neurologist for the evaluation of perioperative risk from 2010 to 2012, patients undergoing moderate to high risk surgery and taking antithrombotics within 30 days were identified. We analyzed the timing of discontinuation and reinitiation of antithrombotic drugs before or after surgery as well as the status of bridging therapy. In addition, the conformity with the guideline suggested by American College of Chest Physicians was assessed. The rate of thromboembolic event and major hemorrhage were also investigated. Results: A total of 329 patients were included. The concordance rate of warfarin stop and restart time with guideline was 23.4% and 10.3%, respectively. Continuing aspirin in patients undergoing coronary artery bypass surgery or non-cardiac surgery in patients with high risk for cardiovascular events were 59.2% and 2.6%, respectively. Bridging therapy was adopted in 92.9% and 81.2% in patients who had received anticoagulant before surgery and who were at high and low risk thromboembolism, respectively. In entire cohorts, 30-day incidence of major bleeding and thromboembolic event were 31.9% and 3.0%. Co-morbid renal disease were shown as independent predictor for major bleeding (adjusted OR 2.65. 95% CI 1.33-5.28). Conclusion: The concordance rate with guideline regarding perioperative antithrombotic use was low and bridging therapy was prevalent in patients undergoing moderate to high risk surgery.
