2024 AHA/ACC/ACS/ASNC/HRS/SCA/SCCT/SCMR/SVM Guideline for Perioperative Cardiovascular Management for Noncardiac Surgery: A Report of the American College of Cardiology/American Heart Association Joint Committee on Clinical Practice Guidelines.

AIM: The "2024 AHA/ACC/ACS/ASNC/HRS/SCA/SCCT/SCMR/SVM Guideline for Perioperative Cardiovascular Management for Noncardiac Surgery" provides recommendations to guide clinicians in the perioperative cardiovascular evaluation and management of adult patients undergoing noncardiac surgery. METHODS: A comprehensive literature search was conducted from August 2022 to March 2023 to identify clinical studies, reviews, and other evidence conducted on human subjects that were published in English from MEDLINE (through PubMed), EMBASE, the Cochrane Library, the Agency for Healthcare Research and Quality, and other selected databases relevant to this guideline. STRUCTURE: Recommendations from the "2014 ACC/AHA Guideline on Perioperative Cardiovascular Evaluation and Management of Patients Undergoing Noncardiac Surgery" have been updated with new evidence consolidated to guide clinicians; clinicians should be advised this guideline supersedes the previously published 2014 guideline. In addition, evidence-based management strategies, including pharmacological therapies, perioperative monitoring, and devices, for cardiovascular disease and associated medical conditions, have been developed.

Preoperative Hepatology and Primary Care Visits Improve Postoperative Outcomes in Patients With Cirrhosis Undergoing Surgery.

BACKGROUND AND AIMS: Cirrhosis patients are at increased risk for postoperative complications. It remains unclear whether preoperative nonsurgical clinician visits improve postoperative outcomes. We assessed the impact of preoperative primary care physician (PCP) and/or gastroenterologist/hepatologist (GI/Hep) visits on postoperative mortality in cirrhosis patients undergoing surgery and explored differences in medication changes and paracentesis rates as potential mediators. METHODS: This was a retrospective cohort study of cirrhosis patients in the Veterans Health Administration who underwent surgery between 2008 and 2016. We compared 1982 patients with preoperative PCP and/or GI/Hep visits with 1846 propensity-matched patients without preoperative visits. We used Cox regression and Fine and Gray competing risk regression to evaluate the association between preoperative visit type and postoperative mortality at 6 months. RESULTS: Patients with preoperative GI/Hep and PCP visits had a 45% lower hazard of postoperative mortality compared with those without preoperative visits (hazard ratio [HR], 0.55; 95% confidence interval [CI], 0.35-0.87). A smaller effect size was noted with GI/Hep preoperative visit alone (HR, 0.69; 95% CI, 0.48-0.99) or PCP visit alone (HR, 0.70; 95% CI, 0.53-0.93). Patients with preoperative PCP/GI/Hep visits were more likely to have diuretics, spontaneous bacterial peritonitis prophylaxis, and hepatic encephalopathy medications newly initiated and/or dose adjusted and more likely to receive preoperative paracentesis as compared with those without preoperative visits. CONCLUSIONS: Preoperative PCP/GI/Hep visits are associated with a reduced risk of postoperative mortality with the greatest risk reduction observed in those with both PCP and GI/Hep visits. This synergistic effect highlights the importance of a multidisciplinary approach in the preoperative care of cirrhosis patients.

Postoperative Adverse Events Following Neoadjuvant Therapy and Surgery for Borderline Resectable Pancreatic Cancer in a Phase 2 Clinical Trial (Alliance A021501).

BACKGROUND: Postoperative adverse events (AEs) in patients with borderline resectable pancreatic ductal adenocarcinoma (BR-PC) treated with neoadjuvant therapy and pancreatectomy in the national cooperative group setting have not been previously characterized. We conducted a preplanned secondary analysis of patients enrolled on the Alliance A021501 clinical trial to quantify perioperative AE rates. METHODS: The A021501 phase 2 trial randomized patients with BR-PC to receive 8 doses of mFOLFIRINOX (Arm 1) or 7 doses of mFOLFIRINOX and hypofractionated radiotherapy (Arm 2), followed by pancreatectomy (December 31, 2016 to May 31, 2019). Adverse events were assessed 90 days after pancreatectomy. RESULTS: Of 126 enrolled patients, 51 (40%) underwent pancreatectomy (n = 32, Arm 1; n = 19, Arm 2) at 28 institutions. Five (10%) patients required reoperation within 90 days; 56% of patients (n = 27/48) experienced at least one grade 3 or higher AE (50% vs. 67%, p = 0.37). Ninety-day mortality was 2.0%. Readmission was less frequent in Arm 1 (16% vs. 42%, p = 0.05), but there were no differences between study arms in rates of reoperation (13% vs. 5%), pancreatic fistula or intra-abdominal abscess requiring drainage (9% vs. 16%), or wound infection (6% vs. 16%). Pancreatic fistula or intra-abdominal abscess requiring drainage was associated with receipt of adjuvant therapy (p = 0.012). No difference in overall survival was observed based on occurrence of postoperative AEs (hazard ratio = 1.1; 95% confidence interval 0.5-2.6). CONCLUSIONS: In this multicenter study, rates of postoperative AEs were consistent with those previously reported. Multimodality trials of preoperative therapy for BR-PC may be performed in the cooperative group setting with careful quality assurance and safety monitoring.

Occurrence of Dumping Syndrome After Esophageal Cancer Surgery: Systematic Review and Meta-analysis.

BACKGROUND: Dumping syndrome occurs frequently after esophageal cancer surgery, but the reported prevalence varied across previous studies. This systematic review and meta-analysis aimed to clarify the prevalence of dumping syndrome after esophageal cancer surgery, particularly exploring the sources of heterogeneity in previous studies. METHODS: A comprehensive literature search was conducted in PubMed, MEDLINE, Web of Science, Embase, and the Cochrane Library databases, supplemented by hand-search of reference lists, through March 2023. Random-effects meta-analysis estimated the average prevalence of dumping syndrome after esophageal cancer surgery. Heterogeneity across studies was examined by the I2 statistic and Cochran's Q test. RESULTS: Among the 2949 articles retrieved from the databases, 16 articles (15 cohort studies and 1 randomized controlled trial) met the inclusion criteria. The prevalence of dumping syndrome ranged 0-74% in these studies, showing high heterogeneity (I2 = 99%, P < 0.01), with the pooled prevalence of 27% (95% confidence interval [CI] 14-39%). The pooled prevalence in the three studies using specialized questionnaires was 67% (95% CI 60-73%), with reduced heterogeneity (I2 = 43%, P = 0.17). The prevalence also varied by year of publication, study population, and length and completeness of follow-up. CONCLUSIONS: Our findings revealed that dumping syndrome is common after esophageal cancer surgery. The varying prevalence across previous studies was probably owing to differences in measurement of dumping syndrome. Using specific patient reported outcome questionnaires is recommended for future investigations on dumping syndrome after esophageal cancer surgery.

Home-Based Trimodal Prehabilitation in Patients with Peritoneal Carcinomatosis Undergoing Cytoreductive Surgery: Effect on Functional Walking Capacity and Skeletal Muscle Mass.

BACKGROUND: Patients with peritoneal carcinomatosis often suffer from loss of skeletal muscle mass and require extensive surgery. Multimodal prehabilitation may improve physical status but its benefits for these specific patients remain unknown. This study aimed to evaluate the effect of prehabilitation on functional walking capacity and skeletal muscle mass, as well as its association with postoperative complications. PATIENTS AND METHODS: A prospective study of patients with peritoneal carcinomatosis following a home-based trimodal prehabilitation program was carried out. Functional walking capacity was assessed with the 6-min walk test (T6MWT), and by the appendicular skeletal muscle index (ASMI) estimated by bioelectrical impedance analysis. Data were collected at the first medical appointment and on the day before surgery. A 90-day postoperative morbidity was registered according to the Clavien-Dindo classification. RESULTS: A total of 62 patients were included in the analysis. Women were more prevalent (77.4%) and peritoneal metastasis from ovarian origin accounted for 48.4%. Clavien II-V grades occurred in 30 (57.7%) patients. After prehabilitation, functional walking capacity improved by 42.2 m (39.62-44.72 m) compared with baseline data (p < 0.001), but no improvement was observed in the ASMI (p = 0.301). Patients able to walk at least 360 m after prehabilitation suffered fewer Clavien-Dindo II-V postoperative complications (p = 0.016). A T6MWT of less than 360 m was identified as an independent risk factor in the multivariable analysis (OR 3.99; 1.01-15.79 p = 0.048). CONCLUSIONS: This home-based trimodal prehabilitation program improved functional walking capacity but not ASMI scores in patients with peritoneal metastasis before surgery. A T6MWT of less than 360 m was found to be a risk factor for postoperative complications.

The Effect of Laparoscopic Gastric Ischemic Preconditioning Prior to Esophagectomy on Anastomotic Stricture Rate and Comparison with Esophagectomy-Alone Controls.

BACKGROUND: Benign anastomotic stricture is a recognized complication following esophagectomy. Laparoscopic gastric ischemic preconditioning (LGIP) prior to esophagectomy has been associated with decreased anastomotic leak rates; however, its effect on stricture and the need for subsequent endoscopic intervention is not well studied. METHODS: This was a case-control study at an academic medical center using consecutive patients undergoing oncologic esophagectomies (July 2012-July 2022). Our institution initiated an LGIP protocol on 1 January 2021. The primary outcome was the occurrence of stricture within 1 year of esophagectomy, while secondary outcomes were stricture severity and frequency of interventions within the 6 months following stricture. Bivariable comparisons were performed using Chi-square, Fisher's exact, or Mann-Whitney U tests. Multivariable regression controlling for confounders was performed to generate risk-adjust odds ratios and to identify the independent effect of LGIP. RESULTS: Of 253 esophagectomies, 42 (16.6%) underwent LGIP prior to esophagectomy. There were 45 (17.7%) anastomotic strictures requiring endoscopic intervention, including three patients who underwent LGIP and 42 who did not. Median time to stricture was 144 days. Those who underwent LGIP were significantly less likely to develop anastomotic stricture (7.1% vs. 19.9%; p = 0.048). After controlling for confounders, this difference was no longer significant (odds ratio 0.46, 95% confidence interval 0.14-1.82; p = 0.29). Of those who developed stricture, there was a trend toward less severe strictures and decreased need for endoscopic dilation in the LGIP group (all p < 0.20). CONCLUSION: LGIP may reduce the rate and severity of symptomatic anastomotic stricture following esophagectomy. A multi-institutional trial evaluating the effect of LGIP on stricture and other anastomotic complications is warranted.

Adjuvant Therapy After Upfront Resection of Resectable Pancreatic Cancer: Patterns of Omission and Use-A Prospective Real-Life Study.

BACKGROUND: Little is known about adjuvant therapy (AT) omission and use outside of randomized trials. We aimed to assess the patterns of AT omission and use in a cohort of upfront resected pancreatic cancer patients in a real-life scenario. METHODS: From January 2019 to July 2022, 317 patients with resected pancreatic cancer and operated upfront were prospectively enrolled in this prospective observational trial according to the previously calculated sample size. The association between perioperative variables and the risk of AT omission and AT delay was analyzed using multivariable logistic regression. RESULTS: Eighty patients (25.2%) did not receive AT. The main reasons for AT omission were postoperative complications (38.8%), oncologist's choice (21.2%), baseline comorbidities (20%), patient's choice (10%), and early recurrence (10%). At the multivariable analysis, the odds of not receiving AT increased significantly for older patients (odds ratio [OR] 1.1, p < 0.001), those having an American Society of Anesthesiologists score ≥II (OR 2.03, p = 0.015), or developing postoperative pancreatic fistula (OR 2.5, p = 0.019). The likelihood of not receiving FOLFIRINOX as AT increased for older patients (OR 1.1, p < 0.001), in the presence of early-stage disease (stage I-IIa vs. IIb-III, OR 2.82, p =0.031; N0 vs. N+, OR 3, p = 0.03), and for patients who experienced postoperative major complications (OR 4.7, p = 0.009). A twofold increased likelihood of delay in AT was found in patients experiencing postoperative complications (OR 3.86, p = 0.011). CONCLUSIONS: AT is not delivered in about one-quarter of upfront resected pancreatic cancer patients. Age, comorbidities, and postoperative complications are the main drivers of AT omission and mFOLFIRINOX non-use. CLINICALTRIALS REGISTRATION: NCT03788382.

Impact of the COVID-19 Pandemic on the Outcomes of Patients Undergoing Oncological Surgeries: CORONAL Study.

BACKGROUND: The impact of coronavirus disease 2019 (COVID-19) on postoperative recovery from oncology surgeries should be understood for the clinical decision-making. Therefore, this study was designed to evaluate the postoperative cumulative 28-day mortality and the morbidity of surgical oncology patients during the COVID-19 pandemic. METHODS: This retrospective cohort study included patients consecutively admitted to intensive care units (ICU) of three centres for postoperative care of oncologic surgeries between March to June 2019 (first phase) and March to June 2020 (second phase). The primary outcome was cumulative 28-day postoperative mortality. Secondary outcomes were postoperative organic dysfunction and the incidence of clinical complications. Because of the possibility of imbalance between groups, adjusted analyses were performed: Cox proportional hazards model (primary outcome) and multiple logistic regression model (secondary outcomes). RESULTS: After screening 328 patients, 291 were included. The proportional hazard of cumulative 28-day mortality was higher in the second phase than that in the first phase in the Cox model, with the adjusted hazard ratio of 4.35 (95% confidence interval [CI] 2.15-8.82). The adjusted incidences of respiratory complications (odds ratio [OR] 5.35; 95% CI 1.42-20.11) and pulmonary infections (OR 1.53; 95% CI 1.08-2.17) were higher in the second phase. However, the adjusted incidence of other infections was lower in the second phase (OR 0.78; 95% CI 0.67-0.91). CONCLUSIONS: Surgical oncology patients who underwent postoperative care in the intensive care unit during the COVID-19 pandemic had higher hazard of 28-day mortality. Furthermore, these patients had higher odds of respiratory complications and pulmonary infections. Trials registration The study is registered in the Brazilian Registry of Clinical Trials under the code RBR-8ygjpqm, UTN code U1111-1293-5414.

The Value of Textbook Outcome in Benchmarking Pancreatoduodenectomy for Nonfunctioning Pancreatic Neuroendocrine Tumors.

BACKGROUND: Textbook outcome (TO) is a composite variable that can define the quality of pancreatic surgery. The aim of this study is to evaluate TO after pancreatoduodenectomy (PD) for nonfunctioning pancreatic neuroendocrine tumors (NF-PanNETs). PATIENTS AND METHODS: All patients who underwent PD for NF-PanNETs (2007-2016) in different centers were included in this retrospective study. TO was defined as the absence of severe postoperative complications and mortality, length of hospital stay ≤ 19 days, R0 resection, and at least 12 lymph nodes harvested. RESULTS: Overall, 477 patients were included. The TO rate was 32%. Tumor size [odds ratio (OR) 1.696; p = 0.013], a minimally invasive approach (OR 12.896; p = 0.001), and surgical volume (OR 2.062; p = 0.023) were independent predictors of TO. The annual frequency of PDs increased over time as well as the overall rate of TO. At a median follow-up of 44 months, patients who achieved TO had similar disease-free (p = 0.487) and overall survival (p = 0.433) rates compared with patients who did not achieve TO. TO rate in patients with NF-PanNET > 2 cm was 35% versus 27% in patients with NF-PanNET ≤ 2 cm (p = 0.044). Considering only NF-PanNETs > 2 cm, patients with TO and those without TO had comparable 5-year overall survival rates (p = 0.766) CONCLUSIONS: TO is achieved in one-third of patients after PD for NF-PanNETs and is not associated with a benefit in terms of long-term survival.

Association of Neoadjuvant Immunotherapy With Postoperative Major Morbidity After Oncologic Surgery.

BACKGROUND: Despite increasing use of immunotherapy in the treatment of various cancer types, understanding of its impact on postoperative complications still is limited. This study aimed to characterize the association between neoadjuvant immunotherapy and surgical outcomes for rectal, colon, anal, esophageal, lung (non-small cell), and oral cavity cancers. METHODS: Using the National Cancer Database (NCDB), the study selected patients ages 18-90 years who underwent non-palliative oncologic surgery between 2010 and 2020. The primary outcome was major morbidity, defined as hospital length of stay within the top decile of each surgery subtype, unplanned 30-day readmission, or 30-day mortality. Multivariable logistic regressions for major morbidity were performed to assess neoadjuvant immunotherapy effects by cancer type while controlling for patient demographics, Charlson-Deyo comorbidity index, cancer staging, procedure type, surgical approach, and other treatment (e.g., chemotherapy or radiotherapy). RESULTS: Of 1,348,334 cases with any of the six cancer types, the study sample included 953,612 cases. Of these cases, 4771 (0.5 %) involved neoadjuvant immunotherapy, and 948,841 (99.5 %) did not. The pooled odds ratio was 0.98 (95% confidence interval [CI] 0.81-1.19). Neoadjuvant immunotherapy was not significantly associated with major morbidity after surgery for rectal (adjusted odds ratio [aOR], 0.83; 95% CI 0.60-1.16), colon (aOR, 1.27; 95% CI 0.87-1.85), anal (aOR, 1.90; 95 % CI 0.16-23.15), esophageal (aOR, 0.35; 95% CI 0.08-1.49), lung (non-small cell) (aOR, 1.06; 95% CI 0.65-1.73), or oral (aOR, 1.10; 95% CI 0.61-2.00) cancer. CONCLUSIONS: Neoadjuvant immunotherapy is not significantly associated with postoperative complications across several cancer types. As the largest study on neoadjuvant immunotherapy postoperative complications, this study suggests that surgery in the setting of neoadjuvant immunotherapy is safe.

Myosteatosis predicts postoperative complications and long-term survival in robotic gastrectomy for gastric cancer: A propensity score analysis.

BACKGROUND: Robotic gastrectomy is increasingly utilized for gastric cancer, but high morbidity remains a concern. Myosteatosis or low skeletal muscle density reflecting fatty infiltration, associates with complications after other cancer surgeries but has not been evaluated for robotic gastrectomy. METHODS: This retrospective study analysed 381 patients undergoing robotic gastrectomy for gastric cancer from September 2019 to October 2022. Myosteatosis was quantified on preoperative computed tomography (CT) images at lumbar 3 (L3). Propensity score matching addressed potential confounding between myosteatosis and non-myosteatosis groups. Outcomes were postoperative complications, 30 days mortality, 30 days readmissions and survival. RESULTS: Myosteatosis was present in 33.6% of patients. Myosteatosis associated with increased overall (47.7% vs. 26.5%, p < 0.001) and severe complications (12.4% vs. 4.9%, p < 0.001). After matching, myosteatosis remained associated with increased overall complications, major complications, intensive care unit (ICU) transfer and readmission (all p < 0.05). Myosteatosis independently predicted overall [odds ratio (OR) = 2.86, 95% confidence interval (CI): 1.57-5.20, p = 0.001] and severe complications (OR = 4.81, 95% CI: 1.51-15.27, p = 0.008). Myosteatosis also associated with reduced overall (85.0% vs. 93.2%, p = 0.015) and disease-free survival (80.3% vs. 88.4%, p=0.029). On multivariate analysis, myosteatosis independently predicted poorer survival [hazard ratio (HR) = 2.83, 95% CI: 1.32-6.08, p=0.012] and disease-free survival (HR = 1.83, 95% CI: 1.01-3.30, p=0.032). CONCLUSION: Preoperative CT-defined myosteatosis independently predicts increased postoperative complications and reduced long-term survival after robotic gastrectomy for gastric cancer. Assessing myosteatosis on staging CT could optimize preoperative risk stratification.

Conversion chemoradiotherapy combined with nab-paclitaxel plus cisplatin in patients with locally advanced borderline-resectable or unresectable esophageal squamous cell carcinoma: a phase i/ii prospective cohort study.

BACKGROUND: To evaluate the efficacy and safety of nab-paclitaxel plus cisplatin as the regimen of conversional chemoradiotherapy (cCRT) in locally advanced borderline resectable or unresectable esophageal squamous cell carcinoma (ESCC). METHODS: Patients with locally advanced ESCC (cT3­4, Nany, M0­1, M1 was limited to lymph node metastasis in the supraclavicular area) were enrolled. All the patients received the cCRT of nab-paclitaxel plus cisplatin. After the cCRT, those resectable patients received esophagectomy; those unresectable patients continued to receive the definitive chemoradiotherapy (dCRT). The locoregional control (LRC), overall survival (OS), event-free survival (EFS), distant metastasis free survival (DMFS), pathological complete response (pCR), R0 resection rate, adverse events (AEs) and postoperative complications were calculated. RESULTS: 45 patients with ESCC treated from October 2019 to May 2021 were finally included. The median follow-up time was 30.3 months. The LRC, OS, EFS, DMFS at 1 and 2 years were 81.5%, 86.6%, 64.3%, 73.2 and 72.4%, 68.8%, 44.8%, 52.7% respectively. 21 patients (46.7%) received conversional chemoradiotherapy plus surgery (cCRT+S). The pCR rate and R0 resection rate were 47.6 and 84.0%. The LRC rate at 1 and 2 years were 95.0%, 87.1% in cCRT+S patitents and 69.3%, 58.7% in dCRT patients respectively (HR, 5.14; 95%CI, 1.10-23.94; P = 0.021). The toxicities during chemoradiotherapy were tolerated, and the most common grade 3-4 toxicitiy was radiation esophagitis (15.6%). The most common postoperative complication was pleural effusion (38.1%) and no grade ≥ IIIb complications were observed. CONCLUSION: nab-paclitaxel plus cisplatin are safe as the regimen of conversional chemoradiotherapy of ESCC.

Patients´ experiences of an exercise intervention in primary care following robot-assisted radical cystectomy due to bladder cancer: a qualitative study.

BACKGROUND: Physical activity is thought to be a key component in reducing postoperative complications following major abdominal surgery. The available literature on exercise interventions following radical cystectomy in patients with bladder cancer is scarce but suggests that physical activity and exercise might improve physical function and health-related quality of life, thus calling for further investigation. The CanMoRe-trial is a single-blinded randomised controlled trial (Clinicals Trials NCT03998579 25/06/2019), aimed at evaluating the impact of an exercise intervention in primary care following robot-assisted radical cystectomy. This study seeks to explore patients' experiences of the exercise intervention in the CanMoRe-trial to gain a better understanding of facilitating aspects and potential barriers. METHODS: A qualitative study was conducted involving 20 patients from the intervention group of the CanMoRe-trial who were interviewed individually between October 2020 and March 2023 using a semi-structured interview guide. The interviews were recorded and transcribed verbatim and reflexive thematic analysis was used to analyse the data. RESULTS: Four main themes were identified: Having to adapt to new circumstances, describing the challenges regarding physical activity patients face after discharge. Optimising conditions for rehabilitation, describing how practical conditions affect patients' ability to exercise. Motivated to get back to normal, describing patients´ desire to get back to normal life and factors influencing motivation. Importance of a supportive environment, describing the impact of social support, support from physiotherapists, and how the environment where exercise takes place impacts patients' ability to exercise. CONCLUSION: This study found that patients participating in the CanMoRe-trial are positive towards physical exercise in PC following radical RARC. They are motivated to get back to normal life but face major challenges when arriving home following surgery, which affect their ability to perform physical activity and engage in exercise. Conditions need to be optimised to support patients' ability to engage in exercise by providing an accessible PC location to perform exercise in. A supportive environment is also needed, including guidance from healthcare professionals regarding which type of exercise, intensity and amount of exercise that should be performed, enabling patients gradually to develop self-efficacy regarding exercise and focusing on goals related to patients' normal lives before surgery.

Association between preoperative anxiety states and postoperative complications in patients with esophageal cancer and COPD: a retrospective cohort study.

BACKGROUND: Esophageal cancer brings emotional changes, especially anxiety to patients. Co-existing anxiety makes the surgery difficult and may cause complications. This study aims to evaluate effects of anxiety in postoperative complications of esophageal cancer patients with chronic obstructive pulmonary disease (COPD). METHODS: Patients with esophageal cancer and co-existing COPD underwent tumor excision. Anxiety was measured using Hospital Anxiety and Depression Scale (HAD) before surgery. Clavien-Dindo criteria were used to grade surgical complications. A multiple regression model was used to analyze the relationship between anxiety and postoperative complications. The chi-square test was used to compare the differences in various types of complications between the anxiety group and the non-anxiety group. A multinomial logistic regression model was used to analyze the influencing factors of mild and severe complications. RESULTS: This study included a total of 270 eligible patients, of which 20.7% had anxiety symptoms and 56.6% experienced postoperative complications. After evaluation by univariate analysis and multivariate logistic regression models, the risk of developing complications in anxious patients was 4.1 times than non-anxious patients. Anxious patients were more likely to develop pneumonia, pyloric obstruction, and arrhythmia. The presence of anxiety, surgical method, higher body mass index (BMI), and lower preoperative oxygen pressure may increase the incidence of minor complications. The use of surgical methods, higher COPD assessment test (CAT) scores, and higher BMI may increase the incidence of major complications, while anxiety does not affect the occurrence of major complications (P = 0.054). CONCLUSION: Preoperative anxiety is associated with postoperative complications in esophageal cancer patients with co-existing COPD. Anxiety may increase the incidence of postoperative complications, especially minor complications in patient with COPD and esophageal cancer.

Impact of preoperative haemoglobin A1c levels on postoperative outcomes in adults undergoing major noncardiac surgery: A systematic review.

AIMS: Diabetes is known to increase morbidity and mortality after major surgery. However, literature is conflicting on whether elevated preoperative haemoglobin A1c (HbA1c) levels are associated with worse outcomes following major noncardiac surgery. We aimed to investigate the effect of incremental preoperative HbA1c levels on postoperative outcomes in adults who had undergone major noncardiac surgery. METHODS: We systematically searched PubMed, EMBASE and the Cochrane Library databases for eligible studies published between January 2012 and July 2023. Randomised controlled trials and observational studies (cohort and case-control studies) which measured HbA1c within 6 months before surgery and compared outcomes between at least three incremental subgroups or analysed HbA1c as a continuous variable were included. The systematic review protocol was registered with PROSPERO (CRD42023391946). RESULTS: Twenty observational studies investigating outcomes across multiple surgical types were included. Higher preoperative HbA1c levels were associated with increased odds of overall postoperative complications, postoperative acute kidney injury, anastomotic leak, surgical site infections and increased length of stay. Each 1% increase in preoperative HbA1c was associated with increased odds of these complications. No association with reoperations and 30-day mortality was identified. The literature was highly variable with respect to composite major complications, perioperative cardiovascular events, hospital readmissions, postoperative pneumonia and systemic thromboembolism. CONCLUSIONS: Current evidence suggested that higher preoperative HbA1c levels were associated with increased odds of postoperative complications and extended length of stay in adults undergoing major noncardiac surgery. Further high-quality studies would be needed to quantify the risks posed and determine whether early intervention improves outcomes.

Clinical usefulness of routinely performed drain fluid cultures after pancreaticoduodenectomy. A new ally to predict patients' outcomes?

BACKGROUND: Previous studies showed that bacterial contamination of surgical drains was associated with higher morbidity and mortality following pancreaticoduodenectomy (PD). However, there is still no agreement on the routine use of fluid drainage cultures in the management of patients underwent PD. Therefore, we aimed to clarify the role of surgical drain bacterial contamination in predicting patients' postoperative course. METHOD: Single-centre study including patients underwent PD at Humanitas Research Hospital (2010-2021). Preoperative, intraoperative and postoperative data were collected. Routinely performed fluid drain cultures on postoperative day (POD) 5 were analyzed and compared among patients throughout the cohort. RESULTS: A total of 825 patients were analyzed. Bacterial contamination of surgical drains was observed in 420 (50.9 %) patients and it was found to be associated with a higher rate of B/C grade pancreatic fistula (POPF) (P < 0.001), Clavien-Dindo≥3 (P < 0.001), 30-day mortality (P = 0.011), wound infection (P < 0.001), relaparotomies (P = 0.003) and greater length of hospital stay (LOS) (P < 0.001). Also, E. coli surgical drain contamination was demonstrated to double the risk of B/C grade POPF development (OR = 1.628, 95 % IC = 1.009-2.625, P = 0.046). Finally, preoperative biliary drainage (OR = 2.474, 95 % IC = 1.855-3.298, P < 0.001), age ≥75 years old (OR = 1.492, 95 % IC = 1.077-2.067, P = 0.016) and isolated Roux-en-Y pancreaticojejunostomy (OR = 1.639, 95 % IC = 1.229-2.188, P < 0.001) were identified as risk factors for surgical drains bacterial contamination. CONCLUSION: Bacterial contamination of surgical drains predicts the development of B/C grade POPF and other major complications after PD. Therefore, we suggest the routine use of fluid drain cultures following PD.

Feasibility and operative outcomes of surgery in the liver area in advanced ovarian cancer.

OBJECTIVE: The study aimed to characterize intra-and postoperative complications according to a standardized anatomo-surgical classification for ovarian cancer metastases in the liver area. METHODS: Data from all patients with advanced ovarian cancer undergoing primary or secondary surgery with perihepatic liver involvement (May-2016 to May-2022), were retrospectively retrieved and classified according to a standardized anatomo-surgical classification, and clustered into four Classes: Class I "Peritoneal", Class II "Hepatoceliac-lymph-nodes", Class III "Parenchymal" and Class IV Mixed (≥ 2 classes). RESULTS: Data from 615 patients were collected. Intraoperative complications were observed in 15%, and severe postoperative complications in 17.6% of cases. While surgical complexity scores were similar, Class IV had longer operative times, higher blood loss, and a 30.4% intraoperative transfusion rate. Class II showed a higher prevalence of vascular injuries (8%). Classes II and IV were significantly associated with severe postoperative complications. Specific complications varied among classes, such as perihepatic collection and intrahepatic hematoma/abscess in Class III (p = 0.003, p < 0.001, respectively), and pleuric effusion, sepsis, anemia, and "other complications" in Class IV (p = 0.002, p = 0.004, p = 0.03, p = 0.03, respectively). Multivariable analysis identified Class II and IV (Class II: OR 4.991, p = 0.045; Class IV: OR 5.331, p = 0.030), Surgical Complexity Score group 3 (OR:3.922, p = 0.003), and the presence of residual tumor (OR:1.748, p = 0.048) as independent risk factors for severe postoperative complications. CONCLUSIONS: Liver procedures during advanced ovarian cancer surgery are feasible with acceptable complication rates According to the anatomo-surgical classification, metastatic patterns are related to both different surgical outcomes and postoperative complication profiles.

Effect of surgical volume on short-term outcomes of cytoreductive surgery for advanced-stage ovarian cancer: A population-based study from the Dutch Gynecological Oncology Audit.

OBJECTIVE: Despite lacking clinical data, the Dutch government is considering increasing the minimum annual surgical volume per center from twenty to fifty cytoreductive surgeries (CRS) for advanced-stage ovarian cancer (OC). This study aims to evaluate whether this increase is warranted. METHODS: This population-based study included all CRS for FIGO-stage IIB-IVB OC registered in eighteen Dutch hospitals between 2019 and 2022. Short-term outcomes included result of CRS, length of stay, severe complications, 30-day mortality, time to adjuvant chemotherapy, and textbook outcome. Patients were stratified by annual volume: low-volume (nine hospitals, <25), medium-volume (four hospitals, 29-37), and high-volume (five hospitals, 54-84). Descriptive statistics and multilevel logistic regressions were used to assess the (case-mix adjusted) associations of surgical volume and outcomes. RESULTS: A total of 1646 interval CRS (iCRS) and 789 primary CRS (pCRS) were included. No associations were found between surgical volume and different outcomes in the iCRS cohort. In the pCRS cohort, high-volume was associated with increased complete CRS rates (aOR 1.9, 95%-CI 1.2-3.1, p = 0.010). Furthermore, high-volume was associated with increased severe complication rates (aOR 2.3, 1.1-4.6, 95%-CI 1.3-4.2, p = 0.022) and prolonged length of stay (aOR 2.3, 95%-CI 1.3-4.2, p = 0.005). 30-day mortality, time to adjuvant chemotherapy, and textbook outcome were not associated with surgical volume in the pCRS cohort. Subgroup analyses (FIGO-stage IIIC-IVB) showed similar results. Various case-mix factors significantly impacted outcomes, warranting case-mix adjustment. CONCLUSIONS: Our analyses do not support further centralization of iCRS for advanced-stage OC. High-volume was associated with higher complete pCRS, suggesting either a more accurate selection in these hospitals or a more aggressive approach. The higher completeness rates were at the expense of higher severe complications and prolonged admissions.

Patient perspectives in adverse event reporting after vaginal apical prolapse surgery.

BACKGROUND: Many clinical trials use systematic methodology to monitor adverse events and determine grade (severity), expectedness, and relatedness to treatments as determined by clinicians. However, patient perspectives are often not included in this process. OBJECTIVE: This study aimed to compare clinician vs patient grading of adverse event severity in a urogynecologic surgical trial. Secondary objectives were to estimate the association of patient grading of adverse events with decision-making and quality of life outcomes and to determine if patient perspective changes over time. STUDY DESIGN: This was a planned supplementary study (Patient Perspectives in Adverse Event Reporting [PPAR]) to a randomized trial comparing 3 surgical approaches to vaginal apical prolapse. In the parent trial, adverse events experienced by patients were collected per a standardized protocol every 6 months during which clinicians graded adverse event severity (mild, moderate, severe/life-threatening). In this substudy, we obtained additional longitudinal patient perspectives for 19 predetermined "PPAR adverse events." Patients provided their own severity grading (mild, moderate, severe/very severe/life-threatening) at initial assessment and at 12 and 36 months postoperatively. Clinicians and patients were masked to each other's reporting. The primary outcome was the interrater agreement (kappa statistic) for adverse event severity between the initial clinician and patient assessment, combining patient grades of mild and moderate. The association between adverse event severity and the Decision Regret Scale, Satisfaction with Decision Scale, the 12-Item Short-Form Health Survey, and Patient Global Impression of Improvement scores was assessed using the Spearman correlation coefficient (ρ) for continuous scales, the Mantel-Haenszel chi-square test for Patient Global Impression of Improvement, and t tests or chi-square tests comparing the assessments of patients who rated their adverse events or symptoms as severe with those who gave other ratings. To describe patient perspective changes over time, the intraobserver agreement was estimated for adverse event severity grade over time using weighted kappa coefficients. RESULTS: Of the 360 randomly assigned patients, 219 (61%) experienced a total of 527 PPAR adverse events (91% moderate and 9% severe/life-threatening by clinician grading). Mean patient age was 67 years; 87% were White and 12% Hispanic. Among the patients reporting any PPAR event, the most common were urinary tract infection (61%), de novo urgency urinary incontinence (35%), stress urinary incontinence (22%), and fecal incontinence (13%). Overall agreement between clinician and participant grading of severity was poor (kappa=0.24 [95% confidence interval, 0.14-0.34]). Of the 414 adverse events that clinicians graded as moderate, patients graded 120 (29%) as mild and 80 (19%) as severe. Of the 39 adverse events graded as severe by clinicians, patients graded 15 (38%) as mild or moderate. Initial patient grading of the most severe reported adverse event was mildly correlated with worse Decision Regret Scale (ρ=0.2; P=.01), 12-Item Short-Form Health Survey (ρ=-0.24; P<.01), and Patient Global Impression of Improvement (P<.01) scores. There was no association between adverse event severity and Satisfaction with Decision Scale score. Patients with an initial grading of "severe" had more regret, lower quality of life, and poorer global impressions of health than those whose worst severity grade was mild (P<.05). Agreement between the patients' initial severity ratings and their ratings at 12 months (kappa=0.48 [95% confidence interval, 0.39-0.58]) and 36 months (kappa=0.45 [95% confidence interval, 0.37-0.53]) was fair. CONCLUSION: Clinician and patient perceptions of adverse event severity are discordant. Worse severity from the patient perspective was associated with patient-centered outcomes. Including the patient perspective provides additional information for evaluating surgical procedures.

Gender-affirming care in urology: emergency care of the gender-affirming surgical patient-what the primary urologist needs to know.

OBJECTIVE: To present a narrative review of fundamental information needed to manage postoperative complications in patients who have undergone genital gender-affirming surgery (GAS). METHODS: A narrative review was performed using the following keywords: 'gender-affirming surgery', 'complications', 'emergency', 'postoperative'. Articles were included after being reviewed by two primary authors for relevance. Four clinicians with significant experience providing both primary and ongoing urological care to patients after GAS were involved in article selection and analysis. RESULTS: The most common feminising genital GAS performed is a vaginoplasty. The main post-surgical complications seen by urologists include wound healing complications, voiding dysfunction, postoperative bleeding, vaginal stenosis, acute vaginal prolapse and graft loss, rectovaginal fistula, and urethrovaginal fistula. The most common masculinising genital GAS options include metoidioplasty and phalloplasty. Complications for these surgeries include urethral strictures, urethral fistulae, and urethral diverticula. Penile implants may also accompany phalloplasties and their complications include infection, erosion, migration, and mechanical failure. CONCLUSION: Genital GAS is increasing, yet there are still many barriers that individuals face not only in accessing the surgeries, but in receiving follow-up care critical for optimal outcomes. Improved education and training programmes would be helpful to identify and manage postoperative complications. Broader cultural level changes are also important to ensure a safe, gender-inclusive environment for all patients.
