Management of Large Ovarian Tumors in Elderly Patients Using the Aron Alpha Method and Principles of Enhanced Recovery after Surgery

Abstract Objectives: We performed preoperative evaluations of giant ovarian tumors in older adult patients using the comprehensive geriatric assessment (CGA) and estimation of physiologic ability and surgical stress (E-PASS) scoring systems. We report a case in which the Aron Alpha method was performed, and perioperative management was performed using enhanced recovery after surgery (ERAS). Materials and Methods: We performed preoperative evaluations using the E-PASS scoring system and CGA on older adult patients with giant ovarian tumors, followed by the minimally invasive Aron Alpha method and perioperative management using ERAS. Results: The mean patient age was 75.8 ± 8.8 years; comorbidities included hypertension in three patients, hyperlipidemia in two, angina pectoris in one, cholecystitis in one, and lower extremity varicose veins in one. The mean tumor size was 21.0 ± 5.4 cm. The E-PASS scoring system showed a preoperative risk score of 0.7 ± 0.4, a surgical stress score of 0, and a comprehensive risk score of 0.3 ± 0.3. CGA showed that two patients had problems with activities of daily living and cognitive function. The mean duration of surgery was 89.0 ± 16.6 min, and the mean blood loss was 56.0 ± 65.4 mL. No surgery-associated complications were observed. No patients had prolonged hospitalization or a decline in activities of daily living. Conclusion: We showed the usefulness of performing detailed preoperative evaluations using CGA and the E-PASS system, followed by the minimally invasive Aron Alpha surgical method and perioperative management using ERAS in improving surgical outcomes in older adult patients with giant ovarian tumors.

Estimation of Physiologic Ability and Surgical Stress (E-PASS) predicts postoperative complications after radical cystectomy.

This study evaluates the effectiveness of the Estimation of Physiologic Ability and Surgical Stress (E-PASS) scoring system in predicting postoperative complications following radical cystectomy (RC). In this single-center retrospective study, we analyzed data from patients who underwent open RC for muscle-invasive bladder cancer by a single surgeon between 2008 and 2023. Cases involving cystectomy for non-urothelial carcinoma or urinary diversion other than ileal conduit were excluded. We recorded patient demographics, body mass index (BMI), history of abdominal/retroperitoneal surgery, ASA score, performance status (PS), and pre-existing conditions, such as hypertension (HT), coronary artery disease (CAD), diabetes mellitus (DM), and chronic kidney disease (CKD). Intraoperative data included surgery duration, blood loss, and need for blood transfusion. Post-operative complications were classified using the Clavien-Dindo system. E-PASS score was calculated using the Preoperative Risk Score (PRS), Surgical Stress Score (SSS), and Comprehensive Risk Score (CRS). The study included 252 patients. Patients who experienced postoperative complications had higher age, BMI, prior surgical history, ASA score, PS, and rates of CAD, HT, DM, and CKD compared to those who did not. Surgery duration, blood loss, blood transfusion requirement, and E-PASS scores (PRS, SSS, CRS) were also higher in this group. The ROC curve for CRS revealed a predictive cutoff of 0.4911 (AUC = 0.905, p < 0.001). Independent risk factors for postoperative complications included high BMI (p = 0.031), longer surgery duration (p < 0.001), HT (p = 0.042), CKD (p = 0.017), and CRS > 0.4911 (p < 0.001). E-PASS system effectively predicts postoperative complications in RC patients.

Efficiency of the estimation of physiologic ability and surgical stress (E-PASS) score in predicting postoperative complications after robot-assisted radical prostatectomy.

Robot-Assisted Radical Prostatectomy (RARP) is increasingly becoming the standard surgical treatment for prostate cancer. While some risk factors for postoperative complications of RARP have been identified, no scoring model that incorporates both preoperative physical status of the patient and intraoperative risk factors has been developed. The Estimation of Physiologic Ability and Surgical Stress (E-PASS) score was initially described to predict postoperative complications after gastrointestinal surgical procedures. This study aims to assess the effectiveness of the E-PASS score in predicting postoperative complications of RARP. A retrospective evaluation was conducted on 204 patients who underwent RARP between 2019 and 2022. Demographic data, parameters indicating patients' preoperative physical condition, and intraoperative risk factors were analyzed. The E-PASS score and subscores were calculated for each patient. Of the patients, 164 (80.4%) were discharged without any postoperative complications (Group 1), and 40 (19.6%) experienced various degrees of complications (Group 2). Patients in Group 2 had higher rates of previous abdominal surgery, elevated Eastern Cooperative Oncology Group (ECOG) performance scores, longer surgical durations, and higher E-PASS scores. To assess the effectiveness of the Comprehensive Risk Score (CRS) as a predictive factor for postoperative complications, a receiver operating characteristic (ROC) curve was constructed with a 95% confidence interval (CI), and a cut-off value was established. The cut-off value for CRS was determined to be -0.0345 (area under the curve [AUC]=0.783, CI: 0.713-0.853; p<0.001). Patients with a CRS higher than the cut-off value had a 16.4 times higher rate of postoperative complications after RARP (95% CI: 5.58-48.5). The E-PASS scoring model successfully predicts postoperative complications in patients undergoing RARP by using preoperative data about the physical status of the patient and surgical risk factors. The E-PASS score and its subscores could be utilized as objective criteria to determine the risk of postoperative complications before and immediately after surgery.

Estimation of physiologic ability and surgical stress (E-PASS) predicts postoperative major complications after hepato-pancreato biliary surgery in the elderly

Estimation of physiologic ability and surgical stress (E-PASS) predicts postoperative major complications after hepato-pancreato biliary surgery in the elderly

Estimation of Physiologic Ability and Surgical Stress (E-PASS) Predicts Postoperative Major Complications After Hepato-Pancreato Biliary Surgery in the Elderly.

As society ages, an increasing number of elderly patients require hepato-pancreato-biliary (HPB) surgery. We investigated the risk factors for complications in elderly patients undergoing HPB surgery using surgical risk scoring models. We retrospectively investigated 184 elderly patients (≥ 65years old) who underwent HPB surgery, including the liver, pancreas, bile duct, and/or gallbladder resection, with exemption to simple cholecystectomy between January 2017 and December 2019. The surgical risk scoring models used included the Estimation of Physiological Ability and Surgical Stress (E-PASS), Physiological and Operative Severity Score for the enUmeration of Mortality and Morbidity (POSSUM), and Geriatric 8 (G8). We evaluated the correlations between the scores and severe complications. Complications were classified as severe (Clavien-Dindo classification [C-D] ≥ III) or non-severe (C-D ≤ II). Complications occurred in 78 patients (24 C-D ≥ III, 54 C-D ≤ II). Preoperative risk score (PRS), surgical stress score (SSS), and comprehensive risk score (CRS) were significantly higher in patients with C-D ≥ IIIa than in those with C-D ≤ II. Multiple logistic regression analysis revealed that PRS (P = 0.01) and SSS (P = 0.04) were independent predictive factors for severe complications. However, the POSSUM and G8 models showed no significant correlations to severe complications. E-PASS is a useful model for predicting complications in elderly patients undergoing HPB surgery.

Usefulness of the estimation of physiologic ability and surgical stress (E-PASS) system for prediction of complication and prognosis in hepatocellular carcinoma patients after hepatectomy.

BackgroundEstimation of physiologic ability and surgical stress (E-PASS) system was verified in predicting postoperative complications or mortality in many surgical operations. This research aimed to investigate whether the E-PASS system could predict postoperative complications and was related with long-term prognosis in primary hepatocellular carcinoma (HCC) patients.MethodsA total of 236 HCC patients who underwent liver resection were collected in this study. We performed univariate analyses to determine the potential risk factors for complications after hepatectomy. The potential independent risk factors were then included in the logistic regression for multivariable analysis. The optimal cutoff value of Comprehensive Risk Score (CRS) was identified by a receiver operating characteristic (ROC) curve. Based on this value, the patients were divided into two groups to investigate the relation between CRS with postoperative complications. The relation between CRS and overall survival (OS) or recurrence-free survival (RFS) was analyzed further in these two groups.ResultsPostoperative complications occurred in 79 patients. Multivariable analysis suggested that CRS was independent factor for predicting postoperative complications (P<0.001). The optimal CRS cutoff value in our study was 0.126. Patients with high Preoperative Risk Score (PRS) had a higher rate of postoperative complications occurrence, both major and mild complications (P<0.001). Our study showed that HCC patients with higher CRS had poorer survival prognosis [hazard ratio (HR): 3.735, 95% confidence interval (CI): 1.200–11.631, P=0.023]. The 3-year OS rate of high CRS group (CRS ≥0.126) and low CRS group (CRS <0.126) were 66.2% vs. 84.8% (P<0.001), respectively.ConclusionsFor HCC patients after liver resection, E-PASS was an effective predictive system for evaluating the risks of postoperative complications and may can predict prognosis in long term.

Surgical Stress Evaluation of Left Lateral Sectionectomy Based on Skeletal Muscle Catabolism.

By examining skeletal muscle catabolism, we aimed to investigate whether laparoscopic left lateral sectionectomy (LLS) is less invasive compared with the open approach. The psoas muscle index (PMI) was measured using computed tomography images before and after surgery. We assessed the relationship between the perioperative PMI reduction rate and the estimation of physiologic ability and surgical stress (E-PASS) score and then compared the PMI reduction rates associated with different approaches. Of the 31 patients, 13 and 18 underwent the open and laparoscopic approaches, respectively. A strong correlation was observed between the PMI reduction rates and surgical stress scores (SSS) ( r =0.561, P <0.01). The laparoscopic approach was associated with a significantly lower PMI reduction rate ( P <0.01) and SSS ( P <0.01) than the open approach. Laparoscopic LLS should be less invasive than the open approach from the perspective of not only perioperative outcomes but also skeletal muscle catabolism.

The Estimation of Physiologic Ability and Surgical Stress (E-PASS) model as a predictor of postoperative complications and mortality after digestive surgeries: a meta-analysis and systematic review.

Conflicting results exist about the usefulness of the Estimation of Physiologic Ability and Surgical Stress (E-PASS) model in patients undergoing digestive surgeries. Thus, this study aims to analyze and evaluate the E-PASS model for predicting postoperative complications and mortality. A literature search strategy for "E-PASS" was carried out in PubMed, Embase, Google Scholar, Ovid, and Cochrane databases for studies published before November 2020. "E-PASS" or "Estimation of Physiologic Ability and Surgical Stress" were used as the search terms in all databases, and a total of 20 published English language studies with available data relating to digestive surgery were selected for this study. Clinical data and indices including preoperative risk score (PRS), surgical stress score (SSS), comprehensive risk score (CRS), postoperative complications, mortality, and overall survival (OS) were collected. Meta-analyses of heterogeneity were performed using Review Manager version 5.3 and STATA 14.0. Twenty studies with 9,136 patients were included in our meta-analysis. Using a random-effects model, the indices of the E-PASS model in patients with postoperative complications were significantly greater than those in patients without complications [PRS: 95% confidence interval (CI): 0.14-1.50; SSS: 95% CI: 0.28-1.06; CRS: 95% CI: 048-1.49]. Moreover, patient morbidity and mortality were associated with a higher CRS (morbidity: 95% CI: 2.17-6.29; mortality: 95% CI: 1.57-4.78), while subgroup analyses showed that a high CRS in the elderly was related to increased morbidity (95% CI: 1.57-4.78) without heterogeneity. In addition, we found that a high E-PASS CRS was significantly associated with shorter OS after digestive surgery (95% CI: 1.24-5.41). The higher CRS score in the E-PASS model accompanies with many postoperative complications, increased mortality and shorter OS. Collectively, the E-PASS model is a convenient and effective risk assessment for patients undergoing digestive surgeries. More stringently designed studies are expected to develop better estimates of the application value of this model in digestive surgeries.

Accurate prediction of severe postoperative complications after pancreatic surgery: POSSUM vs E-PASS.

Few reports have evaluated the differences in the predictive accuracy between the physiological and operative severity score for the enumeration of mortality and morbidity (POSSUM) and estimation of physiologic ability and surgical stress (E-PASS) in pancreatic surgery. Thus, we evaluated the accuracy and similarity of POSSUM and E-PASS for the prediction of severe postoperative complications (PCs) after pancreatic surgery. We enrolled 343 consecutive patients who underwent pancreatic surgery in our department between April 2006 and September 2017.The difference in predictive values of POSSUM and E-PASS for the occurrence of PCs≥Clavien-Dindo grade IIIa (PCs-CD≥IIIa) was nonparametrically compared. The predictive accuracy and similarity of each tool was examined using the receiver operating characteristic (ROC) curve and linear regression analyses. Forty-five patients developed PCs-CD≥IIIa. E-PASS had a significantly higher predictive value for estimating PCs-CD≥IIIa occurrence (P=.002) than did POSSUM. The area under the curve value in ROC analysis was significantly higher in E-PASS than in POSSUM (0.643 vs 0.543, P=.014), with a weak positive correlation in the predictive value between E-PASS and POSSUM (R2 =.333, P<.001). Estimation of physiologic ability and surgical stress was useful for predicting severe PCs after pancreatic surgery and had a higher accuracy than POSSUM.

Pancreaticoduodenectomy can be indicated for elderly patients: risk prediction using the estimation of physiologic ability and surgical stress (E-PASS) system.

Pancreaticobiliary malignant diseases are primarily treated by surgical resection. However, the surgical indications for elderly patients, especially for pancreaticoduodenectomy (PD), must be carefully considered due to patient compliance. Whether PD can contribute to better prognoses in elderly patients remains unclear. Therefore, we aimed to evaluate the complications, compliance, and survival of elderly and non-elderly patients who underwent PD in our department. We retrospectively analyzed 282 patients who underwent PD from 2000 to 2017 and divided them into non-elderly (aged≤79years, n=238) and elderly (aged≥80years, n=44) groups. The estimation of physiologic ability and surgical stress (E-PASS) system was used to evaluate morbidity and mortality using preoperative risk score (PRS), surgical stress score (SSS), and comprehensive risk score (CRS). Preoperative risk score was higher in the elderly group than in the non-elderly group, although SSS and CRS were similar. No significant differences were detected in the occurrence of postoperative complications. In the elderly group, CRS was higher in patients with complications than in those without. Long-term outcomes evaluated by overall and disease-specific survival were not significantly different. In the elderly patients, E-PASS especially CRS can predict the occurrence of complications. The safety and prognoses of elderly patients after PD are comparable with those of non-elderly patients.

E-PASS Scoring System May Be Useful for Prediction of Postoperative Complications in Super Elderly Colorectal Cancer Surgery Patients.

Objectives: Japan is facing an aging society. Elderly individuals are generally more prone to comorbidities and have weaker immune defenses, with ominous prognostic implications if postoperative complications arise. The aim of this study was to explore scoring systems for predicting postoperative morbidity risk in super elderly patients (≥85 years old) after colorectal surgery for cancer. Methods: A population of elderly patients (n = 145) surgically treated for primary colorectal cancer within our department between April 2007 and December 2018 was examined retrospectively, assessing the capacities of various indices, such as Estimation of Physiologic Ability and Surgical Stress (E-PASS), neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), prognostic nutritional index (PNI), and modified Glasgow Prognostic Score (mGPS), to predict postoperative complications. Results: NLR, PLR, and mGPS did not differ significantly in the presence or absence of complications, whereas PNI tended to be lower if complications developed. The E-PASS system showed no group-wise differences in preoperative risk score (PRS), but the surgical stress score (SSS) and the comprehensive risk score (CRS; a composite of PRS and SSS) was significantly higher in patients with complications. Based on the cutoff value calculated from the Receiver operating curve (ROC) for the E-PASS CRS (−0.0580), patients were stratified into low-scoring and high-scoring (HSG) groups. Although not significantly different, the overall survival in the HSG tended to be lower by comparison. Conclusions: The E-PASS scoring system may be a useful predictor of postoperative complications in super elderly patients requiring colorectal cancer surgery.

The use of the E-PASS scoring system in determining complication development in patients with isolated acetabular fractures

The decision to treat acetabular fractures is occasionally deferred or foregone in patients perceived to be unfit for surgery. The previously validated estimation of physiologic ability and surgical stress (E-PASS) score has been shown to predict outcome in a variety of fractures, and consists of a preoperative risk score (PRS), a surgical stress score (SSS), and a comprehensive risk score (CRS). To correlate E-PASS and its components with postoperative complication to quantify risk for individual surgical and patient factors in acetabular fracture management. A retrospective review of patient records was performed for all patients with acetabular fractures surgically treated between January 2013 and June 2018 in a level 1 Trauma Centre. Patients with multiple injuries and/or malignancies were excluded. E-PASS scores were determined with standard demographic data and subscores were correlated with complication development. Of the included 106 patients (mean age 61years, range 17-93), complications were reported in 37 (34.9%) patients and 3 (2.8%) died. Hospital postoperative morbidity and mortality rates increased significantly with the PRS and CRS. The SSS did not correlate significantly with frequency of complications. Age was found to be the only significant independent risk factor (p value=0.031, OR=1.03 per year of age). Latent patient factors have a clear influence on adverse outcomes in contrast to controllable factors such as surgical stress indicating an important role for perioperative care in reducing postoperative complications. Integrated orthogeriatric care with assessment of comorbidities, prevention or early recognition, and treatment of perioperative complications is essential.

Survival outcomes of elderly patients with pathological stages II and III gastric cancer following curative gastrectomy.

AimSurvival outcomes in elderly patients with pathological stages (pStages) II and III gastric cancer remain inadequately elucidated. We retrospectively analyzed outcomes of elderly and nonelderly patients who underwent curative gastrectomy for this cancer and considered clinical results of the Estimation of Physiologic Ability and Surgical Stress (E‐PASS) scoring system for prediction.MethodsAmong 1041 patients who underwent gastrectomy for pStages II and III gastric cancer between 2008 and 2013 consecutively, 898 patients were enrolled. Of these, 158 patients (17.6%) were elderly and 740 patients (82.4%) were nonelderly.ResultsDisease‐specific survival (DSS) in the elderly group with pStage III cancer was significantly worse than that in the same stage nonelderly group (P = .001), while there was no difference in DSS for pStage II cancer between the groups (P = .45). Overall survival (OS) was significantly worse in elderly patients for both pStages II and III. Elderly patients with pStage II cancer had larger survival gaps between OS and DSS compared with those with pStage III cancer. OS for elderly patients with comprehensive risk score (CRS) > 0.159 was significantly worse than that for elderly patients with CRS ≤ 0.159 in pStage II cancer.ConclusionsCompared with nonelderly patients, different characteristics were observed in the survival outcomes of elderly patients between pStages II and III gastric cancer. The survival gap between OS and DSS of elderly patients was larger in pStage II cancer than in pStage III cancer. The E‐PASS scoring system could be a relatively useful predictor in elderly patients.

Mortality and Morbidity Prediction for Older Patients Undergoing Emergency Abdominal Surgery—Comparison of the POSSUM, E-PASS Score, and SASA Score

Several postoperative outcome scoring systems have been developed and validated, combining both pre- and intraoperative factors. Among others are The Portsmouth Physiological and Operative Severity Score for the enUmeration of Mortality and Morbidity (P-POSSUM), the Estimation of Physiologic Ability and Surgical Stress (E-PASS), and the Surgical Apgar Score combined with the American Society of Anesthesiologists (SASA) physical status classification. The aim of this study is to compare the above scoring systems in the prediction of 30-day postoperative mortality and major morbidity in older patients undergoing emergency abdominal surgery. Patients ≥ 65 years were enrolled into the study. Pre- and intraoperative variables were used to calculate the scores and the ROC curve; logistic regression analysis was performed. The study sample comprised 427 older patients with a median age of 77 (range 65–100) years. The most frequent surgical indications were cholecystitis, followed by ileus, complication of colorectal cancer, complicated diverticulitis, and appendicitis. Decreasing SASA and increasing E-PASS and POSSUM/P-POSSUM scores were significantly associated with both 30-day postoperative major complications and death. Multivariate analyses identified all the scores as independent variables to predict postoperative outcomes. The areas under the ROC curve were 0.66–0.81 for predicting mortality and 0.67–0.79 for predicting morbidity (p < 0.01). All the scores were confirmed to be predictive of 30-day postoperative morbidity and mortality. The SASA and the E-PASS scores demonstrated the highest discriminatory ability. However, SASA was found to combine effectiveness and simplicity. Based on this study, we therefore recommend SASA for postoperative risk evaluation in older patients undergoing emergency abdominal surgery.

Clinical study of E-PASS system for peri-operative morbidity of spinal surgery for degenerative scoliosis

Objective To evaluate the feasibility of the Estimation of Physiologic Ability and Surgical Stress (E-PASS) system to predict peri-operative risk in degenerative scoliosis patients scheduled for spinal surgery. Methods Clinical data of 227 cases with degenerative scoliosis (Male∶Female=57∶170, Mean age=66.2±7.7 years), who accepted the operation of instrumentation and fusion in our hospital from January 2013 to July 2017, were retrospectively reviewed according to the E-PASS system, including peri-operative complications. Both hospital stayand post-operative hospital staywere compared between the groups with and withoutthe complications using t test. All E-PASS scores, including Preoperative Risk Score (PRS), Surgical Stress Score (SSS) and Comprehensive Risk Score (CRS), were analyzed between the two groups using Mann-Whitney Utest.The relationship between complications and PRS, SSS and CRS were analyzed using Spearmancorrelation analysis. The predictiveaccuracy of PRS, SSS and CRS were analyzed using the area under the receiver operating characteristic (ROC) curve (AUC). Results There were a total of 47 patients (20.7%) suffering peri-operative complications, including 27 cases (11.9%) with complications at surgical sites and 23 cases (10.1%) with complications at non-surgical sites. Both hospital stay (t=-4.722, P<0.001)and post-operative hospital stay (t= -4.867, P<0.001) were increased because of the complications. All E-PASS scores, including PRS (P=0.005), SSS (P=0.003) and CRS (P<0.001) were significantly higher in patients with peri-operative complications and they were linearly correlated with the overall incidence of the complications(ρ=0.185-0.259). In particular, PRS was correlated with complications at non-surgical sites (ρ=0.162) and SSS with surgical site complications(ρ=0.162). The area under the receiver operating characteristic curve (AUC) for PRS and SSS was higher in patients with complications at non-surgical and surgical sites (AUC=0.655 and 0.650), respectively.The AUC for CRS exhibited good predictive power for both types of complications (AUC=0.662 and 0.631). Conclusion The peri-operative morbidity of spinal surgery for degenerative scoliosis was relatively higher. The E-PASS system could correctly predict the morbidity.

Frailty and postoperative complications in older Chinese adults undergoing major thoracic and abdominal surgery.

Purpose: To determine the association between frailty and postoperative complications in elderly Chinese patients and to determine whether addition of frailty assessment improves the predictive ability of the American Society of Anesthesiologists (ASA) score, Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity (POSSUM), and Estimation of Physiologic Ability and Surgical Stress (E-PASS) score.Patients and methods: A prospective cohort study was conducted in a tertiary hospital. Elderly patients undergoing major thoracic or abdominal surgery were included. Frailty phenotype and ASA, POSSUM, and E-PASS scores were assessed. Demographic, preoperative, and surgical variables were extracted from medical records. Primary outcome measure was in-hospital Clavien-Dindo ≥ grade II complications. Multiple logistic regression was used to examine the association between frailty and complications. Receiver operating characteristic curves were used to explore the predictive ability of frailty.Results: Prevalence of frailty was 26.12%. Significant differences were observed between the frail and non-frail groups with respect to age, Activities of Daily Living, Charlson Comorbidity Index, respiratory function, presence of malignancy, serum albumin, prealbumin, and hemoglobin levels (P<0.05). ASA, POSSUM, and E-PASS scores were higher in the frail group. After adjusting for all covariates, frailty was significantly associated with postoperative complications in hospital [odds ratio: 16.59, 95% CI: 4.56–60.40, P<0.001]. The area under the curve (AUC) for frailty was 0.762 (95% CI: 0.703–0.814). The AUC for ASA, POSSUM, and E-PASS for prediction of complications was 0.751 (95% CI: 0.692–0.804), 0.762 (95% CI: 0.704–0.814), and 0.824 (95% CI: 0.771–0.870), respectively. Addition of frailty assessment increased the AUC to 0.858 (95% CI: 0.808–0.899), 0.842 (95% CI: 0.790–0.885), and 0.854 (95% CI: 0.803–0.896), respectively.Conclusion: Frailty is an effective predictor of postoperative complications in elderly Chinese patients undergoing major thoracic and abdominal surgery. Frailty assessment can improve the predictive ability of current surgical risk assessment tools. Frailty phenotype should be considered perioperatively. Frailty assessment could also expand the scope for nurses to evaluate patients for safety management.

Evaluation of the Estimation of Physiologic Ability and Surgical Stress Score as a Prognostic Indicator for Older Patients with Gastric Cancer

Background: The incidence of gastric cancer (GC) among the older adults is increasing. Therefore, determining postoperative age-associated prognostic factors is clinically important. This present study retrospectively investigated the prognostic significance of the estimation of physiologic ability and surgical stress (E-PASS) of such patients with GC. Methods: We enrolled 136 patients aged ≥75 years with a histopathological diagnosis of gastric adenocarcinoma who underwent gastrectomy. Results: Receiver operating characteristic curves were generated to evaluate survival, and AUC values were compared to assess the discriminatory ability of carcinoembryonic antigen, the perioperative risk score, the surgical stress score, and the comprehensive risk score (CRS) of E-PASS. The AUC value of CRS was of the highest AUC value as a function of overall survival (OS) and disease-specific survival. The 5-year OS rates of CRS^High and CRS^Low groups were 50.6 and 76.9% (p = 0.0007) respectively. The 5-year DSS rates of the CRS^High and CRS^Low groups were 78.8 and 95.2% (p = 0.028) respectively. Further, the 5-year survival rates unrelated to cancer of the CRS^High and CRS^Low groups were 64.2 and 80.9% (p = 0.0096) respectively. Multivariate analysis identified that CRS was an independent prognostic indicator. Conclusions: E-PASS was a useful prognostic indicator for older GC patients.

Assessment of postoperative complications using E-PASS and APACHE II in patients undergoing oral and maxillofacial surgery

BackgroundThe prediction of postoperative complications is important for oral and maxillofacial surgeons. We herein aimed to evaluate the efficacy of the Estimation of Physiologic Ability and Surgical Stress (E-PASS) and Acute Physiology, Age, and Chronic Health Evaluation (APACHE) II scoring systems to predict postoperative complications in patients undergoing oral and maxillofacial surgery.MethodsThirty patients (22 males, 8 females; mean age: 65.1 ± 12.9 years) who underwent major oral surgeries and stayed in the intensive care unit for postoperative management were enrolled in this study. Postoperative complications were discriminated according to the necessity of the therapeutic intervention by the Medical Department, i.e. according to the Clavien–Dingo classification. E-PASS and APACHE II scores as well as laboratory test values were compared between patients with/without postoperative complications.ResultsPostoperative complications were developed in seven patients. The comprehensive risk score (CRS: 1.13 ± 0.24) and APACHE II score (13.0 ± 2.58) were significantly higher in patients with postoperative complications than in those without ones (p < 0.01, p < 0.05, respectively). The CRS showed an appropriate discriminatory power for predicting postoperative complications (area under the curve: 0.814). Furthermore, a correlation was detected between APACHE II scores and postoperative data until C-reactive protein levels decreased to < 1.0 mg/L (r = 0.43, p < 0.05).ConclusionThe E-PASS and APACHE II scoring systems were both shown to be useful to predict postoperative complications after oral and maxillofacial surgery.

An Overview of Risk Stratification in the Elderly Orthopaedic Population

Orthopaedic surgeries are occurring at an increasing frequency in the elderly patient. The goal of this review was to provide exposure to risk stratification scores to help identify high-risk elderly orthopaedic patients. New guidelines have been developed to assess the risk of cardiopulmonary and other perioperative complications. Older scoring systems, such as the American Society of Anesthesiologists (ASA) score and revised cardiac index, are still of importance as they have strong correlation with risks of cardiac and other complications. Other scoring systems, such as the Estimation of Physiologic Ability and Surgical Stress (E-PASS) score and Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity (POSSUM) score, have recently been shown to stratify high-risk elderly patients undergoing hip fracture surgery and other orthopaedic surgeries. The elderly orthopaedic patient has higher risks of perioperative complications than the younger patient. Scoring systems have been developed to help identify those patients at higher risk. Familiarity with these scoring systems will help the practitioner to appropriately select patients for surgery and guide patient counseling on risks on complications and protocols to optimize preoperative care.
