<h4>Objective</h4>This study was done to evaluate whether perioperative propranolol (ß-blocker) in ovarian cancer patients undergoing debulking surgery reduced perioperative tumor growth induced by surgical stress.<h4>Methods</h4>This was a prospective randomized single institution analysis. The primary objective was to compare the changes in CA 125 level (changes between preoperation day 2 and postoperative day 7). As a study arm, patients received a low dose of propranolol 40 mg/day (4×10 mg) ...[more]

Project description:ObjectiveCytoreduction for ovarian cancer is associated with substantial morbidity. We examined the outcome of patients undergoing surgery for ovarian cancer to determine if there are sub-groups of patients who may benefit from alternative treatments.MethodsThe National Surgical Quality Improvement Program database was used to identify women who underwent surgery for ovarian cancer from 2005-2012. Multivariable logistic regression models were used to examine the effect of age, race, functional status, ASA class, preoperative albumin and performance of extended cytoreductive procedures on morbidity, mortality and resource utilization.ResultsA total of 2870 women were identified. The perioperative complication rate increased from 9.5% in women <50years, to 13.4% in those age 60-69years, and 14.6% in women ≥70years (P<0.0001). Similarly, complications rose from 7.3% in those who did not require any extended procedures to 12.9% after 1 procedure, 28.4% for those who had 2, and 30.0% in women who underwent ≥3 extended procedures (P<0.0001). In a series of multivariable models, the number of extended cytoreductive procedures performed and preoperative albumin were the factors most consistently associated with morbidity. Using a series of model fit statistics, compared to chance alone, the ability to predict any complication increased by 27.4% when procedure score was analyzed, 22.0% with preoperative albumin, 11% with age, and 4% with functional status.ConclusionsWhile preoperative clinical and demographic factors may help predict the risk of adverse outcomes for women undergoing surgery for ovarian cancer, performance of extended cytoreductive procedures is the strongest risk factor for complications.

Project description:BackgroundWomen with ovarian cancer have been shown to be at significant risk of malnutrition with incidence rates described as being between 28% to 67%. Nutrition interventions may improve clinical outcomes positively, nutritional status or quality of life measures in this patient group.ObjectivesThis review was conducted to assess the effects of nutrition interventions during the perioperative period for women with ovarian cancer.Search methodsElectronic searches were conducted of the Cochrane Gynaecological Cancer Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL 2012, Issue 7), Medline (1946 to July week 4 2012), Embase (1980 to 2012 week 31), DARE (to 7th August 2012) AMED (1985 to April 2012), BNI (1992 to April 2012), CINAHL (to April 2012). We also searched trials databases, conference proceedings and related citation lists. Reference listings were handsearched. No restrictions were applied on language or date.Selection criteriaRandomised controlled trials (RCTs) in which women 18 years and over with any stage of ovarian cancer, including recurrent cancer, were in the perioperative phase of treatment and received any type of nutrition intervention.Data collection and analysisTitles and abstracts were screened by two review authors with study selection discussed by a team. Pairs of review authors worked independently on data collection and compared findings.Main resultsA total of 4092 titles were screened and 14 full text reports reviewed; a single small study met the inclusion criteria. In the included RCT, 40 women (35 with ovarian cancer) had extensive elective surgery including bowel resection for treatment of gynaecological malignancy. Randomisation was made to either early oral feeding (oral fluids in the first 24 hours, solid foods on the following day) or to a 'traditional' feeding regimen where oral fluids and foods were delayed until there was evidence of bowel function. Most women in the early feeding group (14/18) were able to resume eating solid food one day after surgery. This resulted in a significantly shorter hospital stay with no increase in postoperative complications or change in quality of life measures in comparison with the women on the 'traditional' feeding regimen. The incidence of nausea and vomiting during the postoperative stay was similar in both groups and was noted in slightly more than half of the women. Overall survival was evaluated until 30 days following discharge from hospital; in this period, there was one death of a woman who had been in the 'traditional oral feeding' group, cause of death was not noted. We assessed risk of bias and found no high risk of bias was identified in the methodology and reporting of the included study, although there was an increased risk of bias due to the small size of the study in which not all of the women had ovarian cancer.Authors' conclusionsAlthough women with ovarian cancer have been shown to be at risk of malnutrition, there is a lack of evidence derived from RCTs evaluating the identification, assessment and treatment of malnutrition during the perioperative phase of treatment. There is evidence from one small study that some women with ovarian cancer undergoing surgery with associated bowel resection may safely commence oral fluids within 24 hours of surgery and solid foods on the following day. Further research is required, including a RCT, to generate guidance concerning the treatment of malnutrition in this patient group.

Project description:We assessed whether perioperative fluid management with balanced solutions and a limited volume of hydroxyethyl starch (renal-protective fluid management [RPF] strategy) could improve renal outcomes after cardiovascular surgery.For this retrospective observational study, we evaluated 2613 patients who underwent cardiovascular surgery from January 1, 2010 to December 31, 2013. The control group were given intravenous fluids with saline-based solutions and unlimited volumes of hydroxyethyl starch solutions and the RPF group were given intravenous fluids with RPF. The primary outcome was the incidence of acute kidney injury (AKI) and chronic dialysis within 12 months after cardiovascular surgery. Multivariable regression and propensity analyses were performed to evaluate the association between perioperative fluid management strategy and postoperative renal outcomes.Postoperative AKI and chronic dialysis occurred in 213 (21.2%) and 5 (0.5%) patients in the RPF group compared with 696 (43.2%) and 38 (2.4%) patients in the control group, respectively. After adjustment, the RPF group was linked to a decreased risk of postoperative AKI, severe AKI, persistent AKI, use of renal replacement therapy, chronic kidney disease, chronic dialysis, and a shorter postoperative extubation time and intensive care unit, and hospital stay duration.The perioperative fluid management strategy with balanced solutions and a limited volume of hydroxyethyl starch was related to improved acute and 1-year renal and clinical outcomes after cardiovascular surgery. These findings indicate the need for further definitive clinical trials on perioperative fluid management strategy.

Project description:ObjectiveTo analyse populational trends and perioperative complications following conservative surgery versus oophorectomy in women <50 years of age with ovarian torsion.DesignPopulation-based retrospective observational study.SettingNationwide Inpatient Sample in the USA (2001-2015).PopulationIn all, 89 177 ovarian torsions including 20 597 (23.1%) conservative surgeries and 68 580 (76.9%) oophorectomies.Methods(1) Trend analysis to assess utilisation of conservative surgery over time, (2) multivariable binary logistic regression to identify independent factors associated with conservative surgery and (3) inverse probability of treatment weighting with a generalised estimating equation to analyze perioperative complications.Main outcome measuresTrends, characteristics and complications related to conservative surgery.ResultsPerformance of conservative surgery increased from 18.9 to 25.1% between 2001 and 2015 (32.8% relative increase, P = 0.001) but decreased steadily after age 15, and sharply declined after age 35 (P < 0.001). On multivariable analysis, younger age exhibited the largest effect size for conservative surgery among the independent factors (adjusted odds ratios 3.39-7.96, P < 0.001). In the weighted model, conservative surgery was associated with an approximately 30% decreased risk of perioperative complications overall (10.0% versus 13.6%, odds ratio 0.73, 95% confidence interval 0.62-0.85, P < 0.001) and was not associated with venous thromboembolism (0.2 versus 0.3%, P = 0.457) or sepsis (0.4 versus 0.3%, P = 0.638).ConclusionThere has been an increasing utilisation of conservative surgery for ovarian torsion in the USA in recent years. Our study suggests that conservative surgery for ovarian torsion may not be associated with increased perioperative complications.Tweetable abstractConservative surgery for ovarian torsion may not be associated with increased perioperative complications.

Project description:Background: Previous studies have suggested that dexmedetomidine may have a protective effect on renal function. However, it is currently unclear whether perioperative dexmedetomidine administration is associated with postoperative acute kidney injury (AKI) incidence risk in hypertensive patients undergoing non-cardiac surgery. Methods: This investigation was a retrospective cohort study. Hypertensive patients undergoing non-cardiac surgery in Third Xiangya Hospital of Central South University from June 2018 to December 2019 were included. The relevant data were extracted through electronic cases. The univariable analysis identified demographic, preoperative laboratory, and intraoperative factors associated with acute kidney injury. Multivariable stepwise logistic regression was used to assess the association between perioperative dexmedetomidine administration and postoperative acute kidney injury after adjusting for interference factors. In addition, we further performed sensitivity analyses in four subgroups to further validate the robustness of the results. Results: A total of 5769 patients were included in this study, with a 7.66% incidence of postoperative acute kidney injury. The incidence of postoperative acute kidney injury was lower in the dexmedetomidine-administered group than in the control group (4.12% vs. 8.06%, p < 0.001). In the multivariable stepwise logistic regression analysis, perioperative dexmedetomidine administration significantly reduced the risk of postoperative acute kidney injury after adjusting for interference factors [odds ratio (OR) = 0.56, 95% confidence interval (CI): 0.36-0.87, p = 0.010]. In addition, sensitivity analysis in four subgroups indicated parallel findings: i) eGRF <90 mL/min·1.73/m2 subgroup (OR = 0.40, 95% CI: 0.19-0.84, p = 0.016), ii) intraoperative blood loss <1000 mL subgroup (OR = 0.58, 95% CI: 0.36-0.94, p = 0.025), iii) non-diabetes subgroup (OR = 0.51, 95% CI: 0.29-0.89, p = 0.018), and iv) older subgroup (OR = 0.55, 95% CI: 0.32-0.93, p = 0.027). Conclusion: In conclusion, our study suggests that perioperative dexmedetomidine administration is associated with lower risk and less severity of postoperative acute kidney injury in hypertensive individuals undergoing non-cardiac surgery. Therefore, future large-scale RCT studies are necessary to validate this benefit.

Project description:BackgroundThe fluid balance associated with a better outcome following emergency surgery is unknown. The aim of this study was to explore the association of the perioperative fluid balance and postoperative complications during emergency gastrointestinal surgery.MethodsWe retrospectively included patients undergoing emergency surgery for gastrointestinal obstruction or perforation. A perioperative fluid balance of 2.5 L divided the cohort in a conservative and liberal group. Outcome was Clavien-Dindo graded complications registered 90 days postoperatively. We used logistic regression adjusted for age, sex, American Society of Anesthesiologists' classification, use of epidural analgesia, use of vasopressor, type of surgery, intraabdominal pathology, and hospital. Predicted risk of complications was demonstrated on a continuous scale of the fluid balance.ResultsWe included 342 patients operated between July 2014 and July 2015 from three centers. The perioperative fluid balance was 1.6 L IQR [1.0 to 2.0] in the conservative vs. 3.6 L IQR [3.0 to 5.3] in the liberal group. Odds ratio of overall 2.6 (95% CI 1.5 to 4.4), p < 0.001, and cardiopulmonary complications 3.2 (95% CI 1.9 to 5.7), p < 0.001, were increased in the liberal group. A perioperative fluid balance of 0-2 L was associated with minimal risk of cardiopulmonary complications compared to 1.5-3.5 L for renal complications.ConclusionWe found a perioperative fluid balance above 2.5 L to be associated with an increased risk of overall and cardiopulmonary complications following emergency surgery for gastrointestinal obstruction or perforation. A perioperative fluid balance of 0-2 L was associated with the lowest risk of cardiopulmonary complications and 1.5-3.5 L for renal complications.

Project description:Recent studies have called into question the benefit of perioperative corticosteroids in children undergoing heart surgery, but have been limited by the lack of placebo control, limited power, and grouping of various steroid regimens together in analysis. We evaluated outcomes across methylprednisolone regimens versus no steroids in a large cohort of neonates.Clinical data from the Society of Thoracic Surgeons Database were linked to medication data from the Pediatric Health Information Systems Database for neonates (?30 days) undergoing heart surgery (2004-2008) at 25 participating centers. Multivariable analysis adjusting for patient and center characteristics, surgical risk category, and within-center clustering was used to evaluate the association of methylprednisolone regimen with outcome.A total of 3180 neonates were included: 22% received methylprednisolone on both the day before and day of surgery, 12% on the day before surgery only, and 28% on the day of surgery only; 38% did not receive any perioperative steroids. In multivariable analysis, there was no significant mortality or length-of-stay benefit associated with any methylprednisolone regimen versus no steroids, and no difference in postoperative infection. In subgroup analysis by surgical-risk group, there was a significant association of methylprednisolone with infection consistent across all regimens (overall odds ratio 2.6, 95% confidence interval 1.3-5.2) in the lower-surgical-risk group.This multicenter observational analysis did not find any benefit associated with methylprednisolone in neonates undergoing heart surgery and suggested increased infection in certain subgroups. These data reinforce the need for a large randomized trial in this population.

Project description:Severe obesity in childhood is a major health problem with few effective treatments. Weight-loss surgery (WLS) is being used to treat severely obese adolescents, although with very limited data regarding surgical safety for currently used, minimally invasive procedures.To assess the preoperative clinical characteristics and perioperative safety outcomes of severely obese adolescents undergoing WLS.This prospective, multisite observational study enrolled patients from February 28, 2007, through December 30, 2011. Consecutive patients aged 19 years or younger who were approved to undergo WLS (n?=?277) were offered enrollment into the study at 5 academic referral centers in the United States; 13 declined participation and 22 did not undergo surgery after enrollment, thus the final analysis cohort consisted of 242 individuals. There were no withdrawals.This analysis examined preoperative anthropometrics, comorbid conditions, and major and minor complications occurring within 30 days of operation. All data were collected in a standardized fashion. Reoperations and hospital readmissions were adjudicated by independent reviewers to assess relatedness to the WLS procedure.The mean (SD) age of participants was 17.1 (1.6) years and the median body mass index (calculated as weight in kilograms divided by height in meters squared) was 50.5. Fifty-one percent demonstrated 4 or more major comorbid conditions. Laparoscopic Roux-en-Y gastric bypass, vertical sleeve gastrectomy, and adjustable gastric banding were performed in 66%, 28%, and 6% of patients, respectively. There were no deaths during the initial hospitalization or within 30 days of operation; major complications (eg, reoperation) were seen in 19 patients (8%). Minor complications (eg, readmission for dehydration) were noted in 36 patients (15%). All reoperations and 85% of readmissions were related to WLS.In this series, adolescents with severe obesity presented with abundant comorbid conditions. We observed a favorable short-term complication profile, supporting the early postoperative safety of WLS in select adolescents. Further longitudinal study of this cohort will permit accurate assessment of long-term outcomes for adolescents undergoing bariatric surgery.clinicaltrials.gov Identifier: NCT00474318.

Project description:Malnutrition is a major issue in gastrointestinal perioperative situations, as only 40% of malnourished patients are finally treated. This literature review investigates the inconsistencies regarding the diagnostic approach to both preoperative and postoperative patients and the various underlying causes, as well as the efficiency of the various therapeutic regimens. A literature search was conducted until August 2023 in MEDLINE and Scopus. Clinical studies involving perioperative nutritional assessment in adult gastrointestinal surgery patients during the last 10 years were included in the present review. Finally, 19 articles were included in the study. Preoperative nutritional therapy is increasingly recognized as a key component of surgical care. Malnourished patients who are hospitalized and operated on, have significantly worse clinical results. Gastrointestinal postoperative malnutrition coexists with metabolic stress, as patients usually suffer from minor chronic inflammations; therefore, postoperative malnutrition is the result of a combination of the effects of inflammation and a lack of food intake. Postoperative malnutrition leads to prolonged hospitalizations and hospital complications and therefore the need to treat it is essential. There are many recognized tools for detecting malnutrition. However, all tools showed inconsistent results regarding their validity. Per os feeding after surgery, and dietary supplements when necessary, have been recommended. Therefore, it is very important to reduce malnutrition and define clear strategies towards that direction.

Project description:ObjectivesTo investigate the relationship between obesity status and perioperative outcomes in elderly patients undergoing thoracoscopic anatomic lung cancer surgery.MethodsFrom January 2016 to December 2018, we performed a monocentric retrospective cohort study among 4164 consecutive patients aged 65 years or older who underwent thoracoscopic anatomic lung cancer surgery at Shanghai Chest Hospital. Two groups were stratified by body mass index (BMI): nonobese (BMI<28kg/m2) and obese status (BMI≥28kg/m2). Using a 1:1 propensity score matching (PSM) analysis to compare perioperative outcomes between two groups.Results4035 older patients were eventually enrolled, with a mean age of 69.8 years (range: 65-87), and 305 patients were eligible for obese status, with a mean BMI of 29.8 ± 1.7kg/m2. Compared with nonobese patients, obese patients were more likely to have higher rates of intraoperative hypoxemia (1.2% vs 3.9%, P=0.001) and new-onset arrhythmia (2.3% vs 4.3%, P=0.034). The difference in intraoperative transfusion and conversion rates and postoperative outcomes regarding pulmonary complications, new-onset arrhythmia, transfusion, length of hospital stay, 30-day readmission and hospitalization costs between two groups were not significant (P>0.05). After a 1:1 PSM analysis, the difference in both intraoperative and postoperative complications among two groups were not significant (P>0.05). In subgroup analysis, patients with BMI≥30kg/m2 had a similar incidence of perioperative complications compared to patients with BMI between 28 and 30 kg/m2 (P>0.05).ConclusionsOur research data support evidence for "obesity paradox" and also contribute the growing body of evidence that obesity in older patients should not exclude candidates for thoracoscopic anatomic lung cancer surgery.
