[PMID: 38760264 PMCID: PMC11213983 DOI: 10.1016/j.bja.2024.04.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2023] [Revised: 04/02/2024] [Accepted: 04/02/2024] [Indexed: 05/19/2024] Open
Abstract
BACKGROUND Diabetes mellitus is a significant modulator of postoperative outcomes and is an important risk factor in the patient selection process. We aimed to investigate the effect of diabetes mellitus and use of insulin on outcomes after colorectal resection using a national cohort. METHODS Adults with a recorded colorectal resection in England between 2010 and 2020 were identified from Hospital Episode Statistics data linked to the Clinical Practice Research Database. The primary outcome was 90-day mortality. Secondary outcomes included hospital length of stay (LOS) and readmission within 90 days. RESULTS Of the 106 139 (52 875, 49.8% male) patients included, diabetes mellitus was prevalent in 10 931 (10.3%), 2145 (19.6%) of whom had a record of use of insulin. Unadjusted 90-day mortality risk was 5.7%, with an increased adjusted hazard ratio (aHR) for people with diabetes mellitus (aHR 1.28, 95% confidence interval [CI] 1.19-1.37, P<0.001). This risk was higher in both people with diabetes using insulin (aHR 1.51, 95% CI 1.31-1.74, P<0.001) and not using insulin (aHR 1.22, 95% CI 1.13-1.33, P<0.001), compared with those without diabetes. Ninety-day readmission occurred in 20 542 (19.4%) patients and this was more likely in those with diabetes mellitus (aHR 1.23, 95% CI 1.18-1.29, P<0.001). Median (inter-quartile range) LOS was 8 (5-15) days and was higher in people with diabetes mellitus (adjusted time ratio 1.10, 95% CI 1.08-1.11, P<0.001). CONCLUSIONS People with diabetes mellitus undergoing colorectal resection are at a higher risk of 90-day mortality, prolonged LOS, and 90-day readmission, with use of insulin associated with additional risk.

Variation in the definition of 'failure to rescue' from postoperative complications: a systematic review and recommendations for outcome reporting. Surgery 2024; 175:1103-1110. [PMID: 38245447 DOI: 10.1016/j.surg.2023.12.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2023] [Revised: 11/14/2023] [Accepted: 12/12/2023] [Indexed: 01/22/2024]
Abstract
BACKGROUND Failure to rescue is the rate of death amongst patients with postoperative complications and has been proposed as a perioperative quality indicator. However, variation in its definition has limited comparisons between studies. We systematically reviewed all surgical literature reporting failure to rescue rates and examined variations in the definition of the 'numerator,' 'denominator,' and timing of failure to rescue measurement. METHODS Databases were searched from inception to 31 December 2022. All studies reporting postoperative failure to rescue rates as a primary or secondary outcome were included. We examined the complications included in the failure to rescue denominator, the percentage of deaths captured by the failure to rescue numerator, and the timing of measurement for complications and mortality. RESULTS A total of 359 studies, including 212,048,069 patients, were analyzed. The complications included in the failure to rescue denominator were reported in 295 studies (82%), with 131 different complications used. The median number of included complications per study was 10 (interquartile range 8-15). Studies that included a higher number of complications in the failure-to-rescue denominator reported lower failure-to-rescue rates. Death was included as a complication in the failure to rescue the denominator in 65 studies (18%). The median percentage of deaths captured by the failure to rescue calculation when deaths were not included in the denominator was 79%. Complications (52%) and mortality (40%) were mostly measured in-hospital, followed by 30-days after surgery. CONCLUSION Failure to rescue is an important concept in the study of postoperative outcomes, although its definition is highly variable and poorly reported. Researchers should be aware of the advantages and disadvantages of different approaches to defining failure to rescue.

Comparing 90-Day Postoperative Mortality After Neoadjuvant Proton-Based Versus Photon-Based Chemoradiotherapy for Esophageal Cancer. Int J Part Ther 2024; 11:100012. [PMID: 38757082 PMCID: PMC11095098 DOI: 10.1016/j.ijpt.2024.100012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2023] [Revised: 02/07/2024] [Accepted: 03/05/2024] [Indexed: 05/18/2024] Open
Abstract
Purpose Evidence suggests that proton-beam therapy (PBT) results in less toxicity and postoperative complications compared to photon-based radiotherapy in patients who receive chemoradiotherapy followed by esophagectomy for cancer. Ninety-day mortality (90DM) is an important measure of the postoperative (nononcologic) outcome as proxy of quality-of-care. We hypothesize that PBT could reduce 90DM compared to photon-based radiotherapy. Materials and Methods From a single-center retrospective database patients treated with chemoradiotherapy before esophagectomy for cancer were selected (1998-2022). Univariable logistic regression was used to study the association of radiotherapy modality with 90DM. Three separate methods were applied to adjust for confounding bias, including multivariable logistic regression, propensity score matching, and inverse probability of treatment weighting. Stratified analysis for the age threshold that maximized the difference in 90DM (ie, ≥67 vs <67 years) was performed. Results A total of 894 eligible patients were included and 90DM was 5/202 (2.5%) in the PBT versus 29/692 (4.2%) in the photon-based radiotherapy group (P = .262). After adjustment for age and tumor location, PBT versus photon-based radiotherapy was not significantly associated with 90DM (P = .491). The 90DM was not significantly different for PBT versus photon-based radiotherapy in the propensity score matching (P = .379) and inverse probability of treatment weighting cohort (P = .426). The stratified analysis revealed that in patients aged ≥67 years, PBT was associated with decreased 90DM (1.3% vs 8.8%; P = .026). Higher age significantly increased 90DM risk within the photon-based radiotherapy (8.8% vs 2.7%; P = .001), but not within the PBT group (1.3% vs 3.2%; P = .651). Conclusion No statistically significant difference was observed in postoperative 90DM after esophagectomy for cancer between PBT and photon-based neoadjuvant chemoradiotherapy. However, among older patients a signal was observed that PBT may reduce 90DM risk.

Abstract
INTRODUCTION Thirty-day reoperation rate reflects short-term surgical outcomes following surgery. Laparoscopic surgery for colorectal cancer reportedly has positive effects on postoperative complications. This retrospective study investigated risk factors for 30-day reoperation rate among patients after laparoscopic colorectal cancer surgery using a multicenter database. METHODS Participants comprised 3037 patients who had undergone laparoscopic resection of colorectal cancer between April 2016 and December 2022 at the Nagasaki University and six affiliated centers, classified into those who had undergone reoperation within 30 days after surgery (RO group; n = 88) and those who had not (NRO group; n = 2949). Clinicopathological characteristics were compared between groups. RESULTS In the RO group, anastomotic leakage occurred in 57 patients (64.8%), intestinal obstruction in 12 (13.6%), and intraabdominal abscess in 5 (5.7%). Female patients were more frequent, preoperative treatment less frequent, body mass index (BMI) lower, operation time longer, blood loss greater, and hospital stay longer in the RO group (p < .05 each). Multivariate analysis revealed BMI (odds ratio, 0.415; 95% confidence interval, 0.218-0.787; p = .021) and poor performance status (odds ratio, 1.966; 95% confidence interval, 1.106-3.492; p = .021) as independent predictors of reoperation. CONCLUSION Perioperative measures are warranted for patients with low BMI and poor performance status undergoing laparoscopic colorectal surgery.

Determining the optimal time to report mortality after lobectomy for lung cancer: An analysis of the time-varying risk of death. JTCVS OPEN 2023; 16:931-937. [PMID: 38204618 PMCID: PMC10774977 DOI: 10.1016/j.xjon.2023.08.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/27/2023] [Revised: 06/10/2023] [Accepted: 07/31/2023] [Indexed: 01/12/2024]
Abstract
Objective Surgical mortality has traditionally been assessed at arbitrary intervals out to 1 year, without an agreed optimum time point. The aim of our study was to investigate the time-varying risk of death after lobectomy to determine the optimum period to evaluate surgical mortality rate after lobectomy for lung cancer. Methods We performed a retrospective study of patients undergoing lobectomy for lung cancer at our institution from 2015 to 2022. Parametric survival models were assessed and compared with a nonparametric kernel estimate. The hazard function was plotted over time according to the best-fit statistical distribution. The time points at which instantaneous hazard rate peaked and stabilized in the 1-year period after surgery were then determined. Results During the study period, 2284 patients underwent lobectomy for lung cancer. Cumulative mortality at 30, 90, and 180 days was 1.3%, 2.9%, and 4.9%, respectively. Log-logistic distribution showed the best fit compared with other statistical distribution, indicated by the lowest Akaike information criteria value. The instantaneous hazard rate was greatest during the immediate postoperative period (0.129; 95% confidence interval, 0.087-0.183) and diminishes rapidly within the first 30 days after surgery. Instantaneous hazard rate continued to decrease past 90 days and stabilized only at approximately 180 days. Conclusions In-hospital mortality is the optimal follow-up period that captures the early-phase hazard during the immediate postoperative period after lobectomy. Thirty-day mortality is not synonymous to "early mortality," as instantaneous hazard rate remains elevated well past the 90-day time point and only stabilizes at approximately 180 days after lobectomy.

Abstract
OBJECTIVE To evaluate factors associated with perioperative outcomes in a multi-institutional cohort of patients treated with cytoreductive nephrectomy (CN). METHODS Data were analyzed for metastatic renal cell carcinoma patients treated with CN at 6 tertiary academic centers from 2005 to 2019. Outcomes included: Clavien-Dindo complications, mortality, length of hospitalization, 30-day readmission rate, and time to systemic therapy. Univariate and multivariable models evaluated associations between outcomes and prognostic variables including the year of surgery. RESULTS A total of 1272 consecutive patients were treated with CN. Patients treated in 2015-2019 vs 2005-2009 had better performance status (P<.001), higher pathologic N stage (P = .04), more frequent lymph node dissections (P<.001), and less frequent presurgical therapy (P = .02). Patients treated in 2015-2019 vs 2005-2009 had lower overall and major complications from surgery, 22% vs 39%, P<.001% and 10% vs 16%, P = .03. Mortality at 90days was higher for patients treated 2005-2009 vs 2015-2019; 10% vs 5%, P = .02. After multivariable analysis, surgical time period was an independent predictor of major complications and 90-day mortality following cytoreductive surgery. CONCLUSION Postoperative major complications and mortality rates following CN are significantly lower in patients treated within the most recent time period.

Abstract
BACKGROUND Body mass index (BMI) and waist circumference (WC) were used to evaluate nutritional status and obesity. We aimed to examine whether preoperative BMI or WC was associated with mortality after cancer surgery. METHODS This population-based cohort study used data extracted from the National Health Insurance Service database of South Korea. We included adult patients who underwent major cancer surgery with curative intent between January 1, 2016, and December 31, 2020. RESULTS A total of 87,220 patients were included in the final analysis, and 1,374 (1.6%) died within 90 days after cancer surgery. In the multiple logistic regression model, the BMI < 18.5/kg/m² and > 35 kg/m² groups showed 1.98-fold (odds ratio [OR], 1.98; 95% confidence interval [CI], 1.58-2.49; P < 0.001) and 2.60-fold (OR, 2.60; 95% CI, 1.25-5.40; P < 0.001) higher 90-day mortality after cancer surgery than did the BMI 18.5-24.9 kg/m² group. The 25.0-29.9 kg/m² (P = 0.144) and 30.0-34.9 kg/m² (P = 0.105) BMI groups did not show significant differences compared to the BMI 18.5-24.9 kg/m² group. Compared with the normal WC group, the high (P = 0.052) and very high (P = 0.232) WC groups also did not show significant differences in terms of 90-day mortality. CONCLUSIONS Preoperative BMI < 18.5 kg/m² and > 35 kg/m² is associated with an elevated risk of 90-day mortality after major cancer surgery. However, preoperative WC was not significantly associated with 90-day mortality after cancer surgery.

Abstract
BACKGROUND Several contemporary risk stratification tools are now being used since the development of the Charlson Comorbidity Index (CCI) in 1987. The purpose of this systematic review and meta-analysis was to compare the utility of commonly used co-morbidity indices in predicting surgical outcomes. METHODS A comprehensive review was performed to identify studies reporting an association between a pre-operative co-morbidity measurement and an outcome (30-day/in-hospital morbidity/mortality, 90-day morbidity/mortality, and severe complications). Meta-analysis was performed on the pooled data. RESULTS A total of 111 included studies were included with a total cohort size 25,011,834 patients. The studies reporting the 5-item Modified Frailty Index (mFI-5) demonstrated a statistical association with an increase in the odds of in-hospital/30-day mortality (OR:1.97,95%CI: 1.55-2.49, p < 0.01). The pooled CCI results demonstrated an increase in the odds for in-hospital/30-day mortality (OR:1.44,95%CI: 1.27-1.64, p < 0.01). Pooled results for co-morbidity indices utilizing a scale-based continuous predictor were significantly associated with an increase in the odds of in-hospital/30-day morbidity (OR:1.32, 95% CI: 1.20-1.46, p < 0.01). On pooled analysis, the categorical results showed a higher odd for in-hospital/30-day morbidity (OR:1.74,95% CI: 1.50-2.02, p < 0.01). The mFI-5 was significantly associated with severe complications (Clavien-Dindo ≥ III) (OR:3.31,95% CI:1.13-9.67, p < 0.04). Pooled results for CCI showed a positive trend toward severe complications but were not significant. CONCLUSION The contemporary frailty-based index, mFI-5, outperformed the CCI in predicting short-term mortality and severe complications post-surgically. Risk stratification instruments that include a measure of frailty may be more predictive of surgical outcomes compared to traditional indices like the CCI.

Oh TK, Park HY, Song IA. Association between Preoperative Psychiatric Morbidities and Mortality after Oncologic Surgery: A Nationwide Cohort Study from 2002 to 2019 in South Korea. J Pers Med 2023; 13:1069. [PMID: 37511682 PMCID: PMC10382024 DOI: 10.3390/jpm13071069] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2023] [Revised: 06/19/2023] [Accepted: 06/27/2023] [Indexed: 07/30/2023] Open
Abstract
We aimed to examine whether preoperative psychiatric morbidities affect 30-day postoperative mortality. Using a nationwide registration database in South Korea, the study included all patients who underwent curative cancer surgery from 1 January 2002 to 31 December 2019. Patients underwent surgery for breast, laryngeal, lung, thyroid, gastric, colorectal, esophageal, liver, pancreatic, kidney, bladder, testicular, prostate, vulvar, uterine, or brain cancer. Depression, anxiety disorder, substance abuse, and post-traumatic stress disorder were considered preoperative psychiatric morbidities. Among the 944,794 patients in the final analysis, 5490 (0.6%) died within 30 days of the surgery, and 24,370 (2.6%) had preoperative psychiatric morbidities. Multivariable logistic regression analysis showed that preoperative psychiatric morbidities were associated with a higher (adjusted odds ratio [aOR]: 1.23; 95% confidence interval [CI]: 1.09, 1.39; p = 0.001) 30-day mortality rate than the rate noted for patients without preoperative psychiatric morbidities. This association was significant in the breast (aOR: 3.31, 95% CI: 1.36, 8.07; p = 0.009), lung (aOR: 1.54, 95% CI: 1.19, 2.01; p = 0.001), and kidney (aOR: 1.87, 95% CI: 1.06, 3.31; p = 0.03) cancer groups in the subgroup analyses. In South Korea, preoperative psychiatric morbidities are considered to be associated with increased 30-day postoperative mortality.

Practice variation in anastomotic leak after esophagectomy: Unravelling differences in failure to rescue. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2023; 49:974-982.

Abstract
INTRODUCTION Failure to rescue (FTR) is an important outcome measure after esophagectomy and reflects mortality after postoperative complications. Differences in FTR have been associated with hospital resection volume. However, insight into how centers manage complications and achieve their outcomes is lacking. Anastomotic leak (AL) is a main contributor to FTR. This study aimed to assess differences in FTR after AL between centers, and to identify factors that explain these differences. METHODS TENTACLE - Esophagus is a multicenter, retrospective cohort study, which included 1509 patients with AL after esophagectomy. Differences in FTR were assessed between low-volume (<20 resections), middle-volume (20-60 resections) and high-volume centers (≥60 resections). Mediation analysis was performed using logistic regression, including possible mediators for FTR: case-mix, hospital resources, leak severity and treatment. RESULTS FTR after AL was 11.7%. After adjustment for confounders, FTR was lower in high-volume vs. low-volume (OR 0.44, 95%CI 0.2-0.8), but not versus middle-volume centers (OR 0.67, 95%CI 0.5-1.0). After mediation analysis, differences in FTR were found to be explained by lower leak severity, lower secondary ICU readmission rate and higher availability of therapeutic modalities in high-volume centers. No statistically significant direct effect of hospital volume was found: high-volume vs. low-volume 0.86 (95%CI 0.4-1.7), high-volume vs. middle-volume OR 0.86 (95%CI 0.5-1.4). CONCLUSION Lower FTR in high-volume compared with low-volume centers was explained by lower leak severity, less secondary ICU readmissions and higher availability of therapeutic modalities. To reduce FTR after AL, future studies should investigate effective strategies to reduce leak severity and prevent secondary ICU readmission.

Abstract
The aim of this study was to compare LAP with OPEN regarding short-term mortality, morbidity and completeness of the cancer resection for colon cancer in a routine health care setting using population based register data. All 13,683 patients who were diagnosed 2012-2018 and underwent elective surgery for right-sided or sigmoid colon cancer were included from the Swedish Colorectal Cancer Registry and the National Patient Registry. Primary outcome was 30-day mortality. Secondary outcomes were 90-day mortality, length of hospital stay, reoperation, readmission and positive resection margin (R1). Weighted and unweighted multi regression analyses were performed. There were no difference in 30-day mortality: LAP (0.9%) and OPEN (1.3%) (OR 0.89, 95% CI 0.62-1.29, P = 0.545). The weighted analyses showed an increased 90-day mortality following OPEN, P < 0.001. Re-operations and re-admission were more frequent after OPEN and length of hospital stay was 2.9 days shorter following LAP (P < 0.001). R1 resections were significantly more common in the OPEN group in the unweighted and weighted analysis with P = 0.004 and P < 0.001 respectively. Therefore, the favourable short-term outcomes following elective LAP versus OPEN resection for colon cancer in routine health care indicate an advantage of laparoscopic surgery.

Abstract
BACKGROUND The Canadian Institute for Health Information (CIHI) annually reports on health system performance indicators, including various 30-day in-hospital mortality rates. We aimed to assess the impact of including out-of-hospital deaths on 3 CIHI indicators: 30-day acute myocardial infarction (AMI) in-hospital mortality, 30-day stroke in-hospital mortality and hospital deaths following major surgery. METHODS We followed national cohorts of patients admitted to hospital in 1 of 9 Canadian provinces for AMI, stroke and major surgery for 30-day all-cause mortality in 2 fiscal years (2011/12 and 2016/17). We calculated descriptive statistics to characterize the cohorts. The CIHI Discharge Abstract Database was linked with the Canadian Vital Statistics Death Database using a probabilistic algorithm to identify out-of-hospital deaths. We calculated absolute numbers, relative proportions and 30-day mortality rates for in-hospital, out-of-hospital and all deaths. We compared results between fiscal years. RESULTS We found that hospital admissions increased between fiscal years for each indicator; however, cohort characteristics remained consistent. In 2016/17, the number of out-of-hospital deaths that occurred was 325 for AMI, 545 for stroke and 820 for major surgery. The relative proportions of out-of-hospital deaths ranged from 12.3% for AMI to 14.9% for major surgery in 2016/17 (an increase from 10.6% and 13.1%, respectively, from 2011/12). In-hospital mortality rates improved over time for all 3 indicators, while out-of-hospital mortality rates remained consistent between fiscal years at 0.8% for AMI, 1.9%-2.0% for stroke and 0.2%-0.3% for major surgery. INTERPRETATION Improvements between fiscal years were attributable to reductions in in-hospital mortality, rather than deaths occurring outside of hospitals. Trends over time were the same for each indicator irrespective of whether in-hospital mortality or all deaths were measured.

Abstract
IMPORTANCE The rate of postoperative death in children undergoing tonsillectomy is uncertain. Mortality rates are not separately available for children at increased risk of complications, including young children (aged <3 y) and those with sleep-disordered breathing or complex chronic conditions. OBJECTIVE To estimate postoperative mortality following tonsillectomy in US children, both overall and in relation to recognized risk factors for complications. DESIGN, SETTING, AND PARTICIPANTS Retrospective cohort study based on longitudinal analysis of linked records in state ambulatory surgery, inpatient, and emergency department discharge data sets distributed by the Healthcare Cost and Utilization Project for 5 states covering 2005 to 2017. Participants included 504 262 persons younger than 21 years for whom discharge records were available to link outpatient or inpatient tonsillectomy with at least 90 days of follow-up. EXPOSURES Tonsillectomy with or without adenoidectomy. MAIN OUTCOME AND MEASURES Postoperative death within 30 days or during a surgical stay lasting more than 30 days. Modified Poisson regression with sample weighting was used to estimate postoperative mortality per 100 000 operations, both overall and in relation to age group, sleep-disordered breathing, and complex chronic conditions. RESULTS The 504 262 children in the cohort underwent a total of 505 182 tonsillectomies (median [IQR] patient age, 7 [4-12] years; 50.6% females), of which 10.1% were performed in young children, 28.9% in those with sleep-disordered breathing, and 2.8% in those with complex chronic conditions. There were 36 linked postoperative deaths, which occurred a median (IQR) of 4.5 (2-20.5) days after surgical admission, and most of which (19/36 [53%]) occurred after surgical discharge. The unadjusted mortality rate was 7.04 (95% CI, 4.97-9.98) deaths per 100 000 operations. In multivariable models, neither age younger than 3 years nor sleep-disordered breathing was significantly associated with mortality, but children with complex chronic conditions had significantly higher mortality (16 deaths/14 299 operations) than children without these conditions (20 deaths/490 883 operations) (117.22 vs 3.87 deaths per 100 000 operations; adjusted rate difference, 113.55 [95% CI, 51.45-175.64] deaths per 100 000 operations; adjusted rate ratio, 29.39 [95% CI, 13.37-64.62]). Children with complex chronic conditions accounted for 2.8% of tonsillectomies but 44% of postoperative deaths. Most deaths associated with complex chronic conditions occurred in children with neurologic/neuromuscular or congenital/genetic disorders. CONCLUSIONS AND RELEVANCE Among children undergoing tonsillectomy, the rate of postoperative death was 7 per 100 000 operations overall and 117 per 100 000 operations among children with complex chronic conditions. These findings may inform decision-making for pediatric tonsillectomy.

Abstract
Background Pancreatic exocrine insufficiency (PEI) is a well-defined complication of malignant diseases and pancreatic resection; however, study results of PEI are less consistent. Assessment of PEI by estimation of fecal elastase (FE)-1 in stool by enzyme-linked immunosorbent essay (ELISA) is a relatively inexpensive, noninvasive, and simple test. This study assessed exocrine function of pancreas following pancreaticoduodenectomy (PD) by estimating FE-1. Methods This prospective hospital-based study involved 30 patients who had undergone PD for malignancy. All 30 patients had an uneventful postoperative period under the unit's enhanced recovery after surgery (ERAS) protocol with no Grade B, C postoperative pancreatic fistula/postpancreatectomy hemorrhage as per the International Study Group of Pancreatic Surgery (ISGPS) definitions. Stool samples were collected postoperatively 3 months after surgery from all patients irrespective of clinical symptoms. The analysis was based on a solid phase ELISA used for the quantitative determination of human elastase 1 in feces. Fecal elastase was considered normal if >200 μg/gm stool, moderately reduced if 100-200 μg/gm stool, and severely reduced if <100 μg/gm stool. Results Among 30 patients included, fecal elastase levels were moderately reduced in 10 (33.33%) and severely reduced in 20 (66.67%) patients (P <0.0001). Mean (± standard deviation) of fecal elastase was 87.12 ± 38.76 with median of 74.6 μg/gm stool. There was no significant difference in the fecal elastase levels between men and women (P = 0.057), age (P = 0.48), pancreatic duct diameter (P = 0.609), pancreatic texture (P = 0.286), and presence or absence of clinical symptoms (P = 0.181). Conclusions PD was frequently associated with PEI. Unfortunately PEI is an under recognized and under treated long-term sequel of PD. Fecal elastase 1 should be performed routinely in both symptomatic and asymptomatic patients. Pancreatic enzyme replacement therapy should be considered in every patient after PD.

Video-assisted thoracoscopic lobectomy and bilobectomy versus open thoracotomy for non-small cell lung cancer: Mortality and survival. TURKISH JOURNAL OF THORACIC AND CARDIOVASCULAR SURGERY 2022; 30:66-74. [PMID: 35444859 PMCID: PMC8990136 DOI: 10.5606/tgkdc.dergisi.2022.20912] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/08/2020] [Accepted: 05/17/2021] [Indexed: 11/21/2022]
Abstract
Background
In this study, we aimed to evaluate patients who had non-small cell lung cancer and underwent resection, to investigate our tendency to prefer video-assisted thoracic surgery or open thoracotomy, and to compare 30- and 90-day mortalities and survival rates.
Methods
Between January 2013 and January 2019, a total of 706 patients (577 males, 129 females; mean age: 61.9±8.6 years; range, 17 to 84 years) who underwent lobectomy or bilobectomy due to primary non-small cell lung cancer were retrospectively analyzed. The patients were divided into two groups as operated on through video-assisted thoracic surgery and through open thoracotomy. The 30- and 90-day mortality rates and survival rates were compared.
Results
Of the patients, 202 (28.6%) underwent video-assisted thoracic surgery and 504 (71.4%) underwent open thoracotomy. Lobectomy was performed in 632 patients (89.5%) and bilobectomy was performed in 74 patients (10.5%). Patients who were chosen for video-assisted thoracic surgery were statistically significantly older, did not require any procedure other than lobectomy, did not receive neoadjuvant therapy, had a small tumor, and did not have lymph node metastases. The 30- and 90-day mortality rates in the video-assisted thoracic surgery and open thoracotomy groups were 1.8% vs. 2% and 2.6% vs. 2.5%, respectively. The five-year survival rates of video-assisted thoracic surgery and open thoracotomy groups were 74.1% and 65.2%, respectively (p>0.05). The 30- and 90-day mortality and five-year survival rates were 2.1%, 2.6%, and 73.5% in the video-assisted thoracic surgery group and 2.1%, 2.1%, and 68.5% in the open thoracotomy group, respectively, indicating no statistically significant difference between the two groups.
Conclusion
Throughout the study period, video-assisted thoracic surgery was more preferred in patients with advanced age, in those who had a small tumor, who did not receive neoadjuvant therapy, did not have lymph node metastasis, and did not require any procedure other than lobectomy. In the video-assisted thoracic surgery and open thoracotomy groups, 30- and 90-day mortality and five-year survival rates were similar. Based on these findings, both procedures seem to be acceptable in this patient population.

Abstract
Background 60% of patients diagnosed with lung cancer are older than 65 years and are at risk for substandard treatment due to a reluctance to recommend surgery. Pneumonectomy remains a high risk procedure especially in elderly patients. Nevertheless, the impact of age and neoadjuvant treatment on outcomes after pneumonectomy is still not well described. Methods We performed a multicentric retrospective study, analyzing outcomes of patients older than 70 years who underwent pneumonectomy for central primary lung malignancy between January 2009 and June 2019 in 7 thoracic surgery departments: Lucerne and Bern (Switzerland), Hamilton (Canada), Alicante (Spain), Monza (Italy), London (UK), Leuven (Belgium). Survival was estimated with Kaplan-Meier, and differences in survival were determined by log-rank analysis. We investigated pre- and post-operative prognostic factors using Cox proportional hazards regression model; multivariable analysis was performed only with variables, which were statistically significant at the invariable analysis. Results A total of 136 patients were included in the study. Mean age was 73.8 years (SD 3.6). 24 patients (17.6%) had an induction treatment (chemotherapy alone in 15 patients and chemo-radiation in 9). Mean length of stay (LOS) was 12.6 days (SD 10.39) and 74 patients (54.4%) had experienced a post-operative complication: 29 (21.3%) had a pulmonary complication, 33 (24.3%) had a cardiac complication and in 12 cases (8.8%) patients experienced both cardiac and pulmonary complications. 16 patients were readmitted [median LOS 13.7 days (range, 2–39 days)] and of those 14 (10.3%) required redo surgery. Median overall survival (OS) of the entire cohort was 38 months (95% CI: 29.9–46.1 months); in-hospital mortality was 1.5%, 30-day mortality rate was 3.7%, while 90-day mortality was 8.8% accounting for 5 and 12 patients respectively. Patients receiving neo-adjuvant therapy did not experience a higher incidence of postoperative complications (P=0.633), did not have a longer postoperative course (P=0.588), nor did they have an increased mortality rate (P=0.863). Conclusions Age should not be considered an absolute contraindication for pneumonectomy in elderly patients even after neoadjuvant treatment. It has become apparent that especially in these patients, a patient-tailored approach with a careful selection should be used to define the risk-benefit balance.

Abstract
Background Care Assessment of Need (CAN) scores predicting 90-day mortality and hospitalization are automatically computed each week for patients receiving care at Veterans Health Administration facilities. While currently used only by primary care teams for care coordination, we explored their value as a perioperative risk stratification tool before major elective surgery. Methods We collected relevant demographic and perioperative data along with perioperative CAN scores for veterans who underwent total knee replacement between July 2014 and December 2015. We examined score distribution, relationships of preoperative CAN 1-year mortality scores with 1-year postoperative mortality and index hospital length of stay (LOS), and patterns of mortality. Results Among 8206 patients, 1-year mortality was 1.4% (110 patients), and CAN scores exhibited near-normal distribution. Median scores among survivors were significantly higher than those of in nonsurvivors (45 vs 75; P < .001). The Kaplan-Meier curves showed an approximately 4-fold higher rate of death at 1 year in the highest tercile for 1-year mortality CAN scores compared with those with lower scores (2.0% vs 0.5% respectively; P < .001). Locally estimated scatterplot smoothing curves revealed a significant and nonlinear increase in hospital LOS across preoperative CAN scores. Conclusions Although designed for ambulatory care use, CAN scores can identify patients at high risk for mortality and extended hospital LOS in an elective surgery population. The CAN scores may prove valuable in supporting informed decision making and preoperative planning in high-risk and vulnerable populations. Further study is needed to confirm the validity of CAN scores and compare them to other more widely used surgical risk calculators.

Abstract
OBJECTIVE The aim of this study is to identify factors influencing reoperations following minimally invasive Ivor Lewis esophagectomy and associated mortality and hospital costs. MATERIALS AND METHODS Between 2013 and 2018, 125 patients were retrospectively analyzed. Outcomes included reoperations, mortality, and hospital costs. Multivariable logistic regression analyses determined factors associated with reoperations. RESULTS In-hospital reoperations (n=10) were associated with in-hospital mortality (n=3, P<0.01), higher hospital costs (P<0.01), and longer hospital stay (P<0.01). Conversely, reoperations after discharge were not associated with mortality. By multivariable analysis, baseline cardiovascular (P=0.02) and chronic kidney disease (P=0.01) were associated with reoperations. However, anastomotic leaks were not associated with reoperations nor mortality. CONCLUSION The majority of reoperations occur within 30 days often during index hospitalization. Reoperations were associated with increased in-hospital mortality and hospital costs. Notably, anastomotic leaks did not influence reoperations nor mortality. Efforts to optimize patient baseline comorbidities should be emphasized to minimize reoperations following minimally invasive Ivor Lewis esophagectomy.

Abstract
PURPOSE There is a paucity of data on the effect of intraoperative end-tidal carbon dioxide (EtCO2) levels on postoperative mortality. The purpose of this study was to investigate the relationship between intraoperative EtCO2 and 90-day mortality in patients undergoing major abdominal surgery under general anesthesia. METHODS We conducted a historical cohort study of patients undergoing major abdominal surgery under general anesthesia at Kyoto University Hospital. We measured the intraoperative EtCO2, and patients with a mean EtCO2 value < 35 mm Hg were classified as low EtCO2. The time effect was determined based on minutes below an EtCO2 of 35 mm Hg, and cumulative effects were evaluated by measuring the area under the threshold of 35 mm Hg for each patient. RESULTS Of 4,710 patients, 1,374 (29%) had low EtCO2 and 55 (1.2%) died within 90 days of surgery. Multivariable Cox regression analysis-adjusted for age, American Society of Anesthesiologists Physical Status classification, sex, laparoscopic surgery, emergency surgery, blood loss, mean arterial pressure, duration of surgery, type of surgery, and chronic obstructive pulmonary disease-revealed an association between low EtCO2 and 90-day mortality (adjusted hazard ratio, 2.2; 95% confidence interval [CI], 1.2 to 3.8; P = 0.006). In addition, severity of low EtCO2 was associated with an increased 90-day mortality (area under the threshold; adjusted hazard ratio; 2.9, 95% CI, 1.2 to 7.4; P =0.02); for long-term exposure to an EtCO2 < 35 mm Hg (≥ 226 min), the adjusted hazard ratio for increased 90-day mortality was 2.3 (95% CI, 0.9 to 6.0; P = 0.08). CONCLUSION A mean intraoperative EtCO2 < 35 mm Hg was associated with increased postoperative 90-day mortality.

Abstract
OBJECTIVE The aims of the study were to develop risk-adjusted models and apply them for comparisons of hospital performance to define potentially preventable adverse outcomes (OAs) in Medicare lung resection surgery. METHODS The Medicare Limited Data Set for 2010-2012 was used to design predictive risk models for the four OAs of inpatient deaths, prolonged length-of-stay outliers, 90-day postdischarge deaths without hospital readmission, and 90-day readmissions after removal of unrelated readmission events. The probability of adverse events for each hospital was used to compute the hospital-specific standard deviation (SD) tailored to patient risk profiles. Observed versus predicted adverse events divided by the hospital-specific SD identified the z score for each hospital. Risk-adjusted OA rates were then computed for comparing hospital performance. RESULTS A total of 39,405 lung resection patients from 739 hospitals had 768 inpatient deaths (1.9%), 3147 had prolonged LOS (8.0%), 514 had 90-day postdischarge deaths without readmission (1.3 %), and 7701 had one or more 90-day readmissions (19.5%); 10,924 patients (27.7%) had one or more of these OAs. Twenty-six hospitals were two SDs better than predicted and 34 hospitals were two SDs poorer than predicted. When evaluated by deciles of risk-adjusted OAs, the top performing decile of hospitals had rates of 14.3% and the poorest performing decile had OA rates of 41.0%. CONCLUSIONS The differences in risk-adjusted comparative outcomes between top- and suboptimal-performing hospitals in lung resections define the potential opportunities for care improvement. Identification of risk factors associated with OAs and causes for readmissions provides direction for specific areas of care redesign for improvement.

Abstract
OBJECTIVES The ability to accurately estimate the risk of peri-operative mortality after lung resection is important. There are concerns about the performance and validity of existing models developed for this purpose, especially when predicting mortality within 90 days of surgery. The aim of this study was therefore to develop a clinical prediction model for mortality within 90 days of undergoing lung resection. METHODS A retrospective database of patients undergoing lung resection in two UK centres between 2012 and 2018 was used to develop a multivariable logistic risk prediction model, with bootstrap sampling used for internal validation. Apparent and adjusted measures of discrimination (area under receiving operator characteristic curve) and calibration (calibration-in-the-large and calibration slope) were assessed as measures of model performance. RESULTS Data were available for 6600 lung resections for model development. Predictors included in the final model were age, sex, performance status, percentage predicted diffusion capacity of the lung for carbon monoxide, anaemia, serum creatinine, pre-operative arrhythmia, right-sided resection, number of resected bronchopulmonary segments, open approach and malignant diagnosis. Good model performance was demonstrated, with adjusted area under receiving operator characteristic curve, calibration-in-the-large and calibration slope values (95% confidence intervals) of 0.741 (0.700, 0.782), 0.006 (-0.143, 0.156) and 0.870 (0.679, 1.060), respectively. CONCLUSIONS The RESECT-90 model demonstrates good statistical performance for the prediction of 90-day mortality after lung resection. A project to facilitate large-scale external validation of the model to ensure that the model retains accuracy and is transferable to other centres in different geographical locations is currently underway.

Hospital volume following major surgery for gastric cancer determines in-hospital mortality rate and failure to rescue: a nation-wide study based on German billing data (2009-2017). Gastric Cancer 2021; 24:959-969. [PMID: 33576929 DOI: 10.1007/s10120-021-01167-8] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/11/2020] [Accepted: 01/31/2021] [Indexed: 02/07/2023]
Abstract
BACKGROUND For many cancer resections, a hospital volume-outcome relationship exists. The data regarding gastric cancer resection-especially in the western hemisphere-are ambiguous. This study analyzes the impact of gastric cancer surgery caseload per hospital on postoperative mortality and failure to rescue in Germany. METHODS All patients diagnosed with gastric cancer from 2009 to 2017 who underwent gastric resection were identified from nation-wide administrative data. Hospitals were grouped into five equal caseload quintiles (I-V in ascending caseload order). Postoperative deaths and failure to rescue were determined. RESULTS Forty-six thousand one hundred eighty-seven patients were identified. There was a significant shift from partial resections in low-volume hospitals to more extended resections in high-volume centers. The overall in-house mortality rate was 6.2%. The crude in-hospital mortality rate ranged from 7.9% in quintile I to 4.4% in quintile V, with a significant trend between volume categories (p < 0.001). In the multivariable logistic regression analysis, quintile V hospitals (average of 29 interventions/year) had a risk-adjusted odds ratio of 0.50 (95% CI 0.39-0.65), compared to the baseline in-house mortality rate in quintile I (on average 1.5 interventions/year) (p < 0.001). In an analysis only evaluating hospitals with more than 30 resections per year mortality dropped below 4%. The overall postoperative complication rate was comparable between different volume quintiles, but failure to rescue (FtR) decreased significantly with increasing caseload. CONCLUSION Patients who had gastric cancer surgery in hospitals with higher volume had better outcomes and a reduced failure to rescue rates for severe complications.

Abstract
Background Personalized risk assessment provides opportunities for tailoring treatment, optimizing healthcare resources and improving outcome. The aim of this study was to develop a 90-day mortality-risk prediction model for identification of high- and low-risk patients undergoing surgery for colorectal cancer. Methods This was a nationwide cohort study using records from the Danish Colorectal Cancer Group database that included all patients undergoing surgery for colorectal cancer between 1 January 2004 and 31 December 2015. A least absolute shrinkage and selection operator logistic regression prediction model was developed using 121 pre- and intraoperative variables and internally validated in a hold-out test data set. The accuracy of the model was assessed in terms of discrimination and calibration. Results In total, 49 607 patients were registered in the database. After exclusion of 16 680 individuals, 32 927 patients were included in the analysis. Overall, 1754 (5.3 per cent) deaths were recorded. Targeting high-risk individuals, the model identified 5.5 per cent of all patients facing a risk of 90-day mortality exceeding 35 per cent, corresponding to a 6.7 times greater risk than the average population. Targeting low-risk individuals, the model identified 20.9 per cent of patients facing a risk less than 0.3 per cent, corresponding to a 17.7 times lower risk compared with the average population. The model exhibited discriminatory power with an area under the receiver operating characteristics curve of 85.3 per cent (95 per cent c.i. 83.6 to 87.0) and excellent calibration with a Brier score of 0.04 and 32 per cent average precision. Conclusion Pre- and intraoperative data, as captured in national health registries, can be used to predict 90-day mortality accurately after colorectal cancer surgery.

Surgical outcomes following colorectal cancer resections in patients aged 80 years and over: results from the Australia and New Zealand Binational Colorectal Cancer Audit. Colorectal Dis 2021; 23:814-822. [PMID: 33188657 DOI: 10.1111/codi.15445] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/28/2020] [Revised: 09/30/2020] [Accepted: 10/12/2020] [Indexed: 02/08/2023]
Abstract
AIM The primary aim was to compare the 30-day morbidity and mortality in patients aged ≥80 years undergoing surgery for colorectal cancer with those aged <80 years. The secondary aim was to identify independent outcome predictors. METHOD This was a retrospective study of patients undergoing surgery for colorectal cancer between January 2007 and February 2018. Patients were divided into those <80 years and those ≥80 years at the time of surgery. Data had been collected prospectively by the Australasian Binational Colorectal Cancer Audit and included patient demographics, site and stage of tumour, comorbidity, operative details, American Society of Anesthesiologists score (ASA), pathological staging, 30-day mortality and morbidity (medical and surgical). Univariate and multivariate analyses were used to identify predictors of 30-day morbidity and mortality. RESULTS During the study period, 4600 out of 20 463 (22.5%) patients were ≥80 years. They had a greater 30-day mortality after both colonic (97/2975 [3.3%] vs. 66/7010 [0.9%], P < 0.001) and rectal resections (50/1625 [3.1%] vs. 36/9006 [0.4%], P < 0.001) compared with younger patients. They also had an increased length of stay (colon cancer, 9 vs. 7 days; rectal cancer, 10 vs. 8 days; P < 0.001) and medical complications (colon cancer, 23.5% vs. 12.7%; rectal cancer, 25.2% vs. 11.2%; P < 0.001). Surgical complications were equivalent. Age ≥80 years was not an independent predictor of 30-day morbidity or mortality. Patients ≥80 years who were ASA 2/3 and had rectal cancer seemed to fare worse in terms of 30-day mortality (ASA 2, 22%, 95% CI 9%-36%, P < 0.001; ASA 3, 11%, 95% CI 4%-19%, P< 0.001). CONCLUSIONS Postoperative morbidity and mortality are significantly greater in patients ≥80 years undergoing colorectal cancer surgery. Any recommendation for surgery in this age group should take into account patient comorbidity and not be based on age alone.

Abstract
BACKGROUND Total gastrectomy for gastric cancer is associated with significant 30-day mortality, but this endpoint may underestimate the short-term mortality of the procedure. METHODS Retrospective analysis was performed using the National Cancer Database (2004-2015). Patients who underwent total gastrectomy for stage I to III gastric adenocarcinoma were identified and divided into cohorts based on 90-day mortality. Predictors of mortality were analyzed using multivariable logistic regression, and annual trends in mortality rates were calculated by Joinpoint Regression. RESULTS Of the 5,484 patients who underwent total gastrectomy, 90-day and 30-day mortality rates were 9.1% and 4.7%, respectively. Factors associated with 90-day mortality included increasing age (odds ratio 1.0, P < .001), income below the median (odds ratio 1.2, P = .039), Charlson-Deyo score ≥2 (odds ratio 1.4, P = .039), treatment at low-volume facilities (odds ratio 1.5, P < .001), N1 (odds ratio 2.0, P < .001), N2 (odds ratio 2.0, P < .001), or N3 (odds ratio 2.7, P < .001) stage disease, having <16 lymph nodes harvested (odds ratio 1.5, P < .001), and lack of treatment with chemotherapy (3.7, P < .001). Lack of health insurance (odds ratio 4.1, P = .080), and positive microscopic margins (odds ratio 1.3, P = .080) were correlated, but not significantly associated, with 90-day mortality. The 90-day mortality rate significantly declined from 14.3% in 2004 to 7.9% in 2015 (P = .006), and the 30-day mortality rate significantly declined from 7.7% in 2004 to 4.8% in 2015 (P = .009). CONCLUSION Nearly half of the deaths within 90 days after total gastrectomy for cancer occur beyond 30 days postoperative. Ninety-day mortality has improved over time, but rates remain high, suggesting the need for improved out-of-hospital postoperative care beyond 30 days.

Abstract
Importance Questions have recently arisen as to whether 30-day mortality is a reasonable metric for understanding institutional practice differences after transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR). Objective To examine the utility of 30-day vs 90-day mortality after TAVR and SAVR as a mortality quality metric. Design, Setting, and Participants This nationally representative, multicenter, cohort study analyzed data from Medicare beneficiaries undergoing TAVR and SAVR procedures from January 1, 2012, to December 31, 2015. Concomitant coronary artery bypass grafting and other heart valve or other major open-heart procedures were excluded. Hospitals that performed fewer than 50 TAVR or 70 SAVR procedures per year were excluded to ensure reliable estimates and to reduce the risks of inflated results because of small institutional sample sizes. Data were analyzed from October 2018 to August 2019. Exposures Hospitals were ranked into top- (10%), middle- (80%), and bottom-performing (10%) groups based on their 4-year mean 30-day mortality. Main Outcomes and Measures Changes in hospital performance rankings at 90 days and 1 year and correlation of 30- and 90-day mortality with 1-year mortality were examined. Results A total of 30 329 TAVR admissions at 184 hospitals and 26 021 SAVR admissions at 191 hospitals were evaluated. For TAVR, 40 hospitals (21.7%) changed performance rankings at 90 days: 13 (48.1%) in the top-performing group and 8 (29.6%) in the bottom-performing group. At 1 year, 56 hospitals (30.4%), which included 21 (77.8%) in the top-performing group and 12 (44.4%) in the bottom-performing group, changed rankings. Similar findings were observed for SAVR, with an overall 90-day conversion rate of 17.3% and a 1-year rate of 30.3%. These findings persisted after adjusting for the differences in patient risk profiles among the 3 groups. Capturing 90-day events was also more robustly informative regarding expected 1-year outcomes after both TAVR and SAVR, largely owing to the observed plateau in the instantaneous hazard observed beyond this point. Conclusions and Relevance The findings suggest that evaluation of hospital performance based on 30-day mortality may underestimate outcomes and therefore substantially misrepresent institutional performance after TAVR and SAVR compared with 90-day mortality, even after risk adjustment. Although 30-day mortality has been validated, 90-day mortality may be a more reliable outcome metric for measuring hospital performance and capturing procedure-related mortality.

Abstract
BACKGROUND As age advances, a higher burden of comorbidities and less functional reserve are expected, however, the impact of aging in the surgical outcomes of gastric cancer (GC) patients is unknown. OBJECTIVE The aim of this study is to evaluate surgical outcomes of GC patients according to their age group. METHODS Patients submitted to gastrectomy with curative intent due to gastric adenocarcinoma were divided in quartiles. Each group had 150 patients and age limits were: ≤54.8, 54.9-63.7, 63.8-72, >72. The outcomes assessed were: postoperative complications (POC), 90-day postoperative mortality, disease-free survival (DFS) and overall survival (OS). RESULTS Major surgical complications were 2.7% in the younger quartile vs 12% for the others (P=0.007). Major clinical complications raised according to the age quartile: 0.7% vs 4.7% vs 5.3% vs 7.3% (P<0.042). ASA score and age were independent risk factors for major POC. The 90-day mortality progressively increased according to the age quartile: 1.3% vs 6.0% vs 7.3% vs 14% (P<0.001). DFS was equivalent among quartile groups, while OS was significantly worse for those >72-year-old. D2 lymphadenectomy only improved OS in the three younger quartiles. Age >72 was an independent risk factor for worse OS (hazard ratio of 1.72). CONCLUSION Patients <55-year-old have less surgical complications. As age progresses, clinical complications and 90-day mortality gradually rise. OS is worse for those above age 72, and D2 lymphadenectomy should be individualized after this age.

Abstract
Operative mortality is an important outcome for patients, surgeons, healthcare institutions, and policy makers. Although measures of perioperative mortality have conventionally been limited to in-hospital and 30-day mortality (or a composite endpoint combining both), there is a large body of evidence emerging to support the extension of the perioperative period after lung resection to a minimum of 90 days after surgery. Several large-volume studies from centers across the world have reported that 90-day mortality after lung resection is double 30-day mortality. Hence, true perioperative mortality after lung resection is likely to be significantly higher than what is currently reported. In the contemporary era, where new treatment modalities such as stereotactic ablative body radiotherapy are emerging as viable nonsurgical alternatives for the treatment of lung cancer, accurate estimation of perioperative risk and reliable reporting of perioperative mortality are of particular importance. It is likely that shifting the discussion from 30-day to 90-day mortality will lead to altered decision making, particularly for specific patient subgroups at an increased risk of 90-day mortality. We believe that 90-day mortality should be adopted as the standard measure of perioperative mortality after lung resection and that strategies to reduce the risk of mortality within 90 days of surgery should be investigated.

Abstract
Aims: Interstitial lung disease (ILD) is associated with the incidence of non-small cell lung cancer (NSCLC). Patients with ILD are at risk of acute exacerbation (AE) after pulmonary resection. However, there have been no recognized treatment guidelines for NSCLC patients with ILD on computed tomography (CT). Methods: We reviewed the medical records of 156 consecutive patients with ILD on high-resolution CT who have undergone pulmonary resection and between 2014 and 2018. Data regarding general information, imaging features, perioperative indicators, and long-term prognosis of patients were compared. Results: The mean patient age was 67.24 ± 6.80 years. Postoperative AE occurred in seven (4.5%) patients; five (71.4%) of the seven patients who had an AE died within 30 days. The incidence of postoperative AE was 5.3% among patients who underwent lobectomy (n = 6). Overall survivals (OS) was significantly poorer in patients with possible usual interstitial pneumonia (UIP)/UIP [hazard ratio (HR) 2.34, 95% confidence interval (CI) 1.11–4.95, p = 0.026] and severe postoperative complications (Grade ⩾3) (versus no complication: HR 2.58, 95% CI 1.11–6.02, p = 0.028; versus mild complications: HR 6.05, 95% CI 2.69–13.6, p < 0.001). Age (HR 1.071, 95% CI 1.006–1.137, p = 0.030) and ILD patterns (HR 2.420, 95% CI 1.024–5.716, p = 0.044) were independent prognostic factors for OS. Forced vital capacity (FVC) (odds ratio 0.351, 95% CI 0.145–0.850, p = 0.020) was an independent prognostic factor for patients who needed postoperative intensive care unit intervention. Conclusion: Pulmonary resection for NSCLC Patients with ILD on CT is a safe procedure. However, surgical indications for lobectomy need to be more carefully for these patients, especially for possible UIP/UIP patients and patients with lower FVC. The reviews of this paper are available via the supplemental material section.

Abstract
BACKGROUND The ACS-NSQIP risk calculator predicts perioperative risk. This study tested the calculator's ability to predict risk for outcomes following retroperitoneal sarcoma (RPS) resection. METHODS The United States Sarcoma Collaborative database was queried for adults who underwent RPS resection. Estimated risk for outcomes was calculated twice in the risk calculator, once using sarcoma-specific CPT codes and once using codes indicative of most comorbid organ resection (eg nephrectomy). ROC curves were generated, with area under the curve (AUC) and Brier scores reported to assess discrimination and calibration. An AUC < 0.6 was considered ineffective discrimination. A negative ▲ Brier indicated improved performance relative to baseline outcome rates. RESULTS In total, 482 patients were identified with a 42.3% 90-day complication rate. Discrimination was poor for all outcomes except "all complications" and "renal failure." Baseline outcome rates were better predictors than calculator estimates except for "discharge to nursing or rehab facility" and "renal failure." Replacing sarcoma-specific CPT codes with resection-specific codes did not improve performance. CONCLUSION The ACS-NSQIP risk calculator poorly predicted outcomes following RPS resection. Changing sarcoma-specific CPT to resection-specific codes did not improve performance. Comorbidities in the calculator may not effectively capture perioperative risk. Future work should evaluate a sarcoma-specific calculator.

Abstract
BACKGROUND This study aimed to investigate the association between perioperative antiplatelet (anti-PLT) therapy and 90-d mortality after elective noncardiac surgery. MATERIALS AND METHODS This retrospective cohort study analyzed the medical records of adult patients aged 18 y and older who were admitted to a single tertiary academic hospital between January 1, 2012 and December 31, 2018 for planned elective noncardiac surgery. All patients with a history of coronary artery stent insertion before the day of surgery were excluded from the analysis. Propensity score matching and conditional logistic regression analysis were used for statistical analysis. RESULTS After propensity score matching, a total of 24,710 patients (12,355 in each group) were included in the final analysis. Ninety-day mortalities in the anti-PLT and non-anti-PLT groups were 0.9% (107/12,355) and 1.2% (143/12,355), respectively. The anti-PLT group showed significantly lower odds for 90-d mortality (by 27%) than the non-anti-PLT group (odds ratio, 0.73; 95% confidence interval, 0.55-0.95; P = 0.017). In the sensitivity analysis of the anti-PLT group classified according to the drug type and combination, the aspirin and clopidogrel subgroups significantly showed 23% and 41% lower odds for 90-d mortality compared with the non-anti-PLT group, respectively. The dual anti-PLT groups showed no significant difference in 90-d mortality (P = 0.658). CONCLUSIONS Perioperative anti-PLT therapy (aspirin, clopidogrel, or dual anti-PLT therapy) was associated with lower 90-d mortality after elective noncardiac surgery in adult surgical patients without a coronary stent. This association was most evident in patients on a monotherapy of aspirin or clopidogrel.

Abstract
Background Infectious complications occur in 4–22 per cent of patients undergoing surgical resection of malignant solid tumours. Improving the patient's immune system in relation to oncological surgery with immunonutrition may play an important role in reducing postoperative infections. A meta‐analysis was undertaken to evaluate the potential clinical benefits of immunonutrition on postoperative infections and 30‐day mortality in patients undergoing oncological surgery. Methods PubMed, Embase and Cochrane Library databases were searched to identify eligible studies. Eligible studies had to include patients undergoing elective curative surgery for a solid malignant tumour and receiving immunonutrition orally before surgery, including patients who continued immunonutrition into the postoperative period. The main outcome was overall infectious complications; secondary outcomes were surgical‐site infection (SSI) and 30‐day mortality, described by relative risk (RR) with trial sequential analysis (TSA). Risk of bias was assessed according to Cochrane methodology. Results Some 22 RCTs with 2159 participants were eligible for meta‐analysis. Compared with the control group, immunonutrition reduced overall infectious complications (RR 0·58, 95 per cent c.i. 0·48 to 0·70; I2 = 7 per cent; TSA‐adjusted 95 per cent c.i. 0·28 to 1·21) and SSI (RR 0·65, 95 per cent c.i. 0·50 to 0·85; I2 = 0 per cent; TSA‐adjusted 95 per cent c.i. 0·21 to 2·04). Thirty‐day mortality was not altered by immunonutrition (RR 0·69, 0·33 to 1·40; I2 = 0 per cent). Conclusion Immunonutrition reduced overall infectious complications, even after controlling for random error, and also reduced SSI. The quality of evidence was moderate, and mortality was not affected by immunonutrition (low quality). Oral immunonutrition merits consideration as a means of reducing overall infectious complications after cancer surgery.

Abstract
Management of intrathoracic anastomotic leakage after esophagectomy by means of endoscopic stent insertion has gained wide acceptance as an alternative to surgical reintervention. Between January 2004 and March 2013 all patients who underwent esophagectomy at a German high-volume center for esophageal surgery were included in this retrospective study. The study comprises 356 patients. Anastomotic leakage occurred in 49 cases. There were no significant differences in age, American Society of Anesthesiologists (ASA) score, or frequency of neoadjuvant therapy between cases with and without leak. However, leak patients sustained significantly more often postoperative pneumonia, pleural empyema, sepsis, and acute renal failure. Moreover, leak victims had higher odds for fatal outcome (16 of 49 vs 33 of 307; odds ratio, 5.94; 95% confidence interval, 2.65 to 13.15; P < 0.0001). The leakage was amendable by endoscopic stenting in 29 cases, whereas rethoracotomy was mandatory in 20 patients. Between stent and rethoracotomy cases, we observed no significant differences in age, ASA score, neoadjuvant therapy, occurrence of pneumonia, pleural empyema, or tracheostomy rate. Rethoracotomy patients sustained more often sepsis (16 of 20 vs 14 of 29; P = 0.04) and acute renal failure (nine of 20 vs four of 29; P = 0.02) as expression of more severe septic disease. Nevertheless, there was no significant difference in mortality (seven of 29 vs nine of 20; P = 0.21). Furthermore, we observed three cases of stent-related aortic erosion with peracute death from exsanguination. Despite being the preferred treatment option, endoscopic stenting was only feasible in approximately 60 per cent of all intrathoracic leaks. The results are marred by the occurrence of deadly vascular erosion. Therefore, individualized strategies should be preferred to a general recommendation for endoscopic stenting.

Abstract
Operative management of esophageal carcinoma in the very elderly is still controversially discussed. It is not yet decided whether the risk warrants the procedure. The aim of this study is to analyze the outcome of esophagectomy for esophageal cancer in the very elderly. Factors influencing the clinical course and determining the outcome are identified. A retrospective study 292 consecutive cases of esophagectomy for nonmetastatic esophageal cancer at a German tertiary referral hospital between 2004 and 2011 were reviewed. Two age groups (75 years or older and younger than 75 years) were formed. The mean age was 63 years. Altogether 45 patients were 75 years or older. There were no significant differences in American Society of Anesthesiologists score, operative procedure, or in the frequency of anastomotic leakage between the age groups. However, very elderly patients with anastomotic leak had an eight times higher risk for fatal outcome than the very elderly without leak (odds ratio [OR], 8.54; 95% confidence interval [CI], 1.0 to 112.18; P = 0.025). Moreover, the odds for postoperative death were five times higher in very elderly patients with leak than in younger patients sustaining anastomotic leakage (OR, 5.67; 95% CI, 0.67 to 73.83; P = 0.046). In general, the very elderly had a three times higher risk for a fatal outcome (OR, 3.30; 95% CI, 1.37 to 7.86; P = 0.008). In-hospital mortality of the very elderly was 11 out of 45 compared with 8 per cent (20 of 247) in the younger group. Fatal outcome was more often caused by medical (seven) than by surgical complications (four cases). The remaining 34 patients recovered well. Very elderly patients undergoing esophagectomy have no elevated risk for occurrence of surgical complications, whereas the mortality of these complications is much higher. Improved outcome is achievable by timely management of postoperative surgical as well as medical complications. Notwithstanding the increased mortality, esophagectomy should be considered in thoroughly selected very elderly patients with curable esophageal carcinoma.

Abstract
BACKGROUND The chronic use of opioids and glucocorticoids is associated with serious side effects. Moreover, both medications are related to poor long-term postoperative outcomes. OBJECTIVE The study aimed to investigate the association between pre-operative chronic opioid and glucocorticoid use and 90-day mortality after noncardiac surgery. DESIGN Retrospective, population-based cohort study. SETTING Single tertiary academic hospital. PATIENTS The study enrolled adult (≥18 years of age) patients admitted to Seoul National University Bundang Hospital, between January 2012 and December 2018 for planned, elective, noncardiac surgery. MAIN OUTCOME MEASURES The study compared the 90-day mortality for patients using opioids or glucocorticoids chronically (≥3 months) prior to surgery and for opioid-naïve and glucocorticoid-naïve patients. RESULTS A total of 112 606 patients were included in the study. Among them, 107 843 (95.9%) were opioid-naïve and glucocorticoid-naïve patients; 3373 (3.0%), 1199 (1.1%) and 191 patients (0.2%) were chronic users of opioids, glucocorticoids or both, respectively. In the multivariable model, compared with opioid-naïve and glucocorticoid-naïve patients, the odds of dying within 90 days were significantly higher for chronic users of opioids [3.56-fold; 95% confidence intervals (CIs) 2.36 to 5.38; P < 0.001], glucocorticoids (4.17-fold; 95% CI 3.28 to 5.29; P < 0.001) and combined opioids and glucocorticoids (7.66-fold; 95% CI 3.91 to 15.01; P < 0.001). CONCLUSION Chronic pre-operative use of opioids and glucocorticoids, together or individually, were associated with increased 90-day mortalities after noncardiac surgery, compared with opioid-naïve and glucocorticoid-naïve patients. Our results suggest that chronic pre-operative use of opioids and glucocorticoids should be managed carefully.

Abstract
BACKGROUND The Barcelona Clinic Liver Cancer (BCLC) staging system is widely applied to stage hepatocellular carcinoma (HCC). However, it may be inaccurate when applied to East Asian HCC patients. In this study, a large Chinese HCC cohort was analyzed to evaluate possible modifications for the BCLC staging system. METHODS Between January 1995 and December 2009, 622 HCC patients who underwent hepatectomy were enrolled. Prognostic risk factors were analyzed using univariate and multivariate analyses. The ability of the modified system to predict survival was evaluated by determining the area under the receiver operating characteristic curve. RESULTS Patients without bile duct tumor thrombus (BDTT; 1-, 3- and 5-year overall survival, 80%, 60% and 48%, respectively) showed a substantial survival advantage over those with BDTT (1-, 3- and 5-year overall survival, 77%, 42% and 23%, respectively; χ2 = 6.280, P = 0.012). In BCLC stage 0-A patients, significant differences were identified between the BDTT group and the non-BDTT group, while no such differences were found in BCLC stage B patients. Based on this finding, BCLC stage 0-A BDTT patients were recategorized into stage B. The modified BCLC classification featured better performance in the prediction of overall survival than the original system (modified BCLC χ2 = 53.596, P < 0.001; original BCLC χ2 = 46.335, P < 0.001). The ability to predict mortality was also slightly higher using the modified BCLC system. CONCLUSIONS Modification of the BCLC system to include BDTT status might further enhance its prognostic ability.

Abstract
Background Radical cystectomy is still the gold standard for muscle-invasive bladder carcinoma (MIBC) treatment. In order to reduce postoperative complications, multimodality bladder-sparing therapies could be a good alternative. Studies in various malignancies have shown that the modified Frailty Index (mFI) may be more useful for identifying high-risk patients. Objectives We investigated the possible correlation between the mFI in cystectomy patients with MIBC and serious complications 30 and 90 days postoperatively. Methods Analysis of a prospective database of 109 consecutive MIBC patients who underwent a cystectomy between January 2012 and August 2017 was performed. The mFI was added retrospectively. Differences between groups were tested with independent t-tests, Mann-Whitney U tests, ANOVA, Kruskal-Wallis test, or Chi square tests as appropriate. Univariate and multivariate logistic regression analysis were performed to analyse the relation between the mFI and complications. Results Patients with Clavien-Dindo ≥ 3 at 30 and 90 days postoperatively had a significantly higher mFI compared to patients with Clavien-Dindo < 3: the odds ratio of the mFI for serious complications within 30 days was 1.5 (95% confidence interval 1.1-2.1, p = 0.010) and for 90 days was 1.5 (95% confidence interval 1.1-2.1, p = 0.008). Conclusions We found an association between a high mFI and postoperative complications and mortality. The mFI is therefore useful when discussing treatment options with MIBC patients.

Abstract
OBJECTIVES Mortality rates of 5% to 10% after pneumonectomy have remained constant during the last decade. To understand the patterns of outcomes after pneumonectomy, we investigated the time-varying risks of readmission and death during the first postoperative year and examined the contributions of specific causes to these patterns over time. METHODS We retrospectively reviewed all pneumonectomies for lung cancer at our institution from 2000 to 2018. The time-varying instantaneous risk of all-cause readmission and mortality up to 1 year after pneumonectomy was estimated using parametric analyses and was repeated for each primary cause of readmission (oncologic, infectious, pulmonary, cardiac, or other) and death (oncologic or nononcologic). RESULTS In our cohort of 355 patients who underwent pneumonectomy, risk of readmission was highest immediately after discharge and was halved by 14 days. This risk reached a nadir and remained constant from 4 to 8 months, after which it gradually increased. Pulmonary causes accounted for most readmissions within 90 days, after which oncologic causes predominated. Likewise, the overall risk of death was highest immediately after surgery, was halved by 7 days, reached a nadir at 90 days, and then increased throughout the remainder of the first year. All deaths during the first 90 days after surgery were due to nononcologic causes. CONCLUSIONS Nononcologic causes of readmission and death predominate in the first 90 days after pneumonectomy, after which oncologic causes prevail. We also identify specific causes that pose the highest risk of readmission immediately after discharge. Efforts are warranted to define the effects of specific causes of readmission on overall mortality after pneumonectomy.

Abstract
OBJECTIVES To develop a simplified version of the Eurolung risk model to predict cardiopulmonary morbidity and 30-day mortality after lung resection from the ESTS database. METHODS A total of 82 383 lung resections (63 681 lobectomies, 3617 bilobectomies, 7667 pneumonectomies and 7418 segmentectomies) recorded in the ESTS database (January 2007-December 2018) were analysed. Multiple imputations with chained equations were performed on the predictors included in the original Eurolung models. Stepwise selection was then applied for determining the best logistic model. To develop the parsimonious models, different models were tested eliminating variables one by one starting from the less significant. The models' prediction power was evaluated estimating area under curve (AUC) with the 10-fold cross-validation technique. RESULTS Cardiopulmonary morbidity model (Eurolung1): the best parsimonious Eurolung1 model contains 5 variables. The logit of the parsimonious Eurolung1 model was as follows: -2.852 + 0.021 × age + 0.472 × male -0.015 × ppoFEV1 + 0.662×thoracotomy + 0.324 × extended resection. Pooled AUC is 0.710 [95% confidence interval (CI) 0.677-0.743]. Mortality model (Eurolung2): the best parsimonious model contains 6 variables. The logit of the parsimonious Eurolung2 model was as follows: -6.350 + 0.047 × age + 0.889 × male -0.055 × BMI -0.010 × ppoFEV1 + 0.892 × thoracotomy + 0.983 × pneumonectomy. Pooled AUC is 0.737 (95% CI 0.702-0.770). An aggregate parsimonious Eurolung2 was also generated by repeating the logistic regression after categorization of the numeric variables. Patients were grouped into 7 risk classes showing incremental risk of mortality (P < 0.0001). CONCLUSIONS We were able to develop simplified and updated versions of the Eurolung risk models retaining the predictive ability of the full original models. They represent a more user-friendly tool designed to inform the multidisciplinary discussion and shared decision-making process of lung resection candidates.

Abstract
(1) Background: Oncological gastrectomy requires complex multidisciplinary management. Clinical pathways (CPs) can potentially facilitate this task, but evidence related to their use in managing oncological gastrectomy is limited. This study evaluated the effect of a CP for oncological gastrectomy on process and outcome quality. (2) Methods: Consecutive patients undergoing oncological gastrectomy before (n = 64) or after (n = 62) the introduction of a CP were evaluated. Assessed parameters included catheter and drain management, postoperative mobilization, resumption of diet and length of stay. Morbidity, mortality, reoperation and readmission rates were used as indicators of outcome quality. (3) Results: Enteral nutrition was initiated significantly earlier after CP implementation (5.0 vs. 7.0 days, p < 0.0001). Readmission was more frequent before CP implementation (7.8% vs. 0.0%, p = 0.05). Incentive spirometer usage increased following CP implementation (100% vs. 90.6%, p = 0.11). Mortality, morbidity and reoperation rates remained unchanged. (4) Conclusions: After implementation of an oncological gastrectomy CP, process quality improved, while indicators of outcome quality such as mortality and reoperation rates remained unchanged. CPs are a promising tool to standardize perioperative care for oncological gastrectomy.

Abstract
OBJECTIVE The aim of this study was to investigate the association between preadmission statin use and 90-day mortality after planned elective noncardiac surgery in adult patients. SUMMARY BACKGROUND DATA Statin therapy is known to have pleiotropic effects, which improve the outcomes of various diseases. However, the effect of perioperative statin therapy on postoperative mortality remains controversial. METHODS This retrospective cohort study analyzed the medical records of adult patients who were admitted to a single tertiary academic hospital for elective noncardiac surgery between January 2012 and December 2018. The primary endpoint was 90-day mortality, which was defined as any mortality within 90 days after surgery. The secondary endpoint was overall survival. RESULTS After propensity score matching, a total of 33,514 patients (16,757 patients in each group) were included in the analysis. The logistic regression analysis of the propensity score-matched cohort indicated that the odds ratio (OR) of 90-day mortality in the statin group was 26% lower than that of the nonstatin group [OR: 0.74; 95% confidence interval (CI): 0.59 to 0.92; P = 0.009]. The sensitivity analysis indicated that the high-dose intensity statin group had a 61% lower 90-day mortality rate than the nonstatin group (OR: 0.39; 95% CI: 0.18-0.84; P = 0.016). The overall survival time was significantly longer in the statin group than in the nonstatin group after propensity score matching (P < 0.001 by log-rank test). CONCLUSIONS Preoperative statin use was associated with lower 90-day mortality and longer overall survival for adult patients who underwent elective noncardiac surgery. This association was more evident for high-intensity statin users.

Abstract
BACKGROUND Postoperative hyperchloremia is known to be related to increases in mortality and morbidity after surgery. However, the relationship between preoperative hyperchloremia and hypochloremia and postoperative mortality and morbidity is not well established. Our aim was to evaluate the relationship between preoperative hyperchloremia or hypochloremia, as assessed using preoperative serum chloride tests, and 90-day mortality and morbidity after noncardiac surgery. METHODS In this retrospective cohort study, we reviewed the medical records of patients >20 years of age who underwent noncardiac surgery between January 2010 and December 2016. Patients were categorized into one of the following groups on the basis of the results of serum chloride testing performed within 1 month before surgery: normochloremia, 97-110 mmol·L; hyperchloremia, >110 mmol·L; and hypochloremia, <97 mmol·L. The primary end point of this study was the difference in postoperative 90-day mortality among the preoperative serum chloride groups. The secondary end point was the difference in postoperative acute kidney injury incidence among the preoperative serum chloride groups. RESULTS A total of 106,505 patients were included in the final analysis (2147 were allocated to the preoperative hypochloremia group and 617 to the hyperchloremia group). Multivariable Cox regression analysis revealed significantly increased 90-day mortality in the hypochloremia (hazard ratio, 1.46; 95% CI, 1.16-1.84; P = .001) and hyperchloremia (hazard ratio, 1.76; 95% CI, 1.13-2.73; P = .013) groups when compared with the normochloremia group. In addition, multivariable logistic regression analysis revealed a 1.83-fold increased odds of acute kidney injury in the preoperative hypochloremia group when compared with the normochloremia group (odds ratio, 1.83; 95% CI, 1.53-2.19; P < .001). CONCLUSIONS Preoperative hypochloremia and hyperchloremia were related to increased 90-day mortality after noncardiac surgery. In addition, preoperative hypochloremia was related to an increased risk for postoperative acute kidney injury.

Abstract
Importance Distant recurrence following preoperative chemoradiotherapy and resection in patients with gastroesophageal adenocarcinoma is common. Adjuvant chemotherapy may improve survival. Objective To compare adjuvant chemotherapy with postoperative observation following preoperative chemoradiotherapy and resection in patients with gastroesophageal adenocarcinoma. Design, Setting, and Participants Propensity score-matched analysis using the National Cancer Database. We included adult patients who received a diagnosis between 2006 and 2013 of clinical stage T1N1-3M0 or T2-4N0-3M0 adenocarcinoma of the distal esophagus or gastric cardia who were treated with preoperative chemoradiotherapy and curative-intent resection. Patients receiving adjuvant chemotherapy were matched by propensity score to patients undergoing postoperative observation. Exposures Adjuvant chemotherapy and postoperative observation. Main Outcomes and Measures Overall survival. Results We identified 10 086 patients (8840 [88%] male; mean [SD] age, 61 [9.5] years), 9272 in the postoperative observation group and 814 in the adjuvant chemotherapy group. Patients receiving adjuvant chemotherapy were younger (18-54 years: 252 [31%] vs 1989 [21%]; P < .001) and were more likely to have advanced disease (ypT3/4: 458 [62%] vs 3531 [46%]; P < .001; ypN+: 572 [72%] vs 3428 [39%]; P < .001), as well as shorter postoperative inpatient stays (>2 weeks: 94 [13%] vs 1589 [20%]; P < .001). A total of 732 patients in the adjuvant chemotherapy group were matched by propensity score to 3660 patients in the postoperative observation group. Adjuvant chemotherapy was associated with improved overall survival compared with postoperative observation (median survival: 40 months; 95% CI, 36-46 months vs 34 months; 95% CI, 32-35 months; stratified log-rank P < .001; hazard ratio, 0.79; 95% CI, 0.72-0.88). Overall survival at 1, 3, and 5 years was 88%, 47%, and 34% in the observation group, and 94%, 54%, and 38% in the adjuvant chemotherapy group, respectively. Adjuvant chemotherapy was associated with a survival benefit compared with postoperative observation in most patient subgroups. Conclusions and Relevance For patients with locally advanced gastroesophageal adenocarcinoma treated with preoperative chemoradiotherapy and resection, adjuvant chemotherapy was associated with improved overall survival. Our findings have important implications for the postoperative treatment of this patient group for which few data are available.

Optimizing histopathologic evaluation of EMR specimens of Barrett's esophagus-related neoplasia: a randomized study of 3 specimen handling methods. Gastrointest Endosc 2019; 90:384-392.e5.

Abstract
BACKGROUND AND AIMS Endoscopic resection is the cornerstone of treatment of Barrett's esophagus (BE)-related neoplasia. However, accurate histopathologic evaluation of endoscopic resection specimens can be challenging, and the preferred specimen handling method remains unknown. Therefore, the aim of our study was to compare 3 different specimen handling methods for assessment of all clinically relevant histopathologic parameters and time required for specimen handling. METHODS In this multicenter, randomized study EMR specimens of BE-related neoplasia with no suspicion of submucosal invasion during endoscopy were randomized to 3 specimen handling methods: pinning on paraffin using needles, direct fixation in formalin without prior tissue handling, and the cassette technique (small box for enclosing specimens). The histopathologic evaluation scores were assessed by 2 dedicated GI pathologists blinded to the handling method. RESULTS Of the 126 randomized EMR specimens, 45 were assigned to pinning on paraffin, 41 to direct fixation in formalin, and 40 to the cassette technique. The percentages of specimens with overall optimal histopathologic evaluation scores were similar for the pinning method (98%; 95% confidence interval [CI], 88.0-99.9) and for no handling (90%; 95% CI, 76.9-97.3) but were significantly lower (64%; 95% CI, 47.2-78.8) for the cassette technique (P < .001). Time required for specimen handling was shortest when no handling method was used (P < .001 vs pinning and cassette). CONCLUSIONS Both pinning on paraffin and direct fixation in formalin resulted in optimal histopathologic evaluation scores in a high proportion of specimens, whereas the cassette technique performs significantly worse, and its use in clinical daily practice should be discouraged. Given the significantly shorter handling time, direct fixation in formalin appears to be the preferred method over pinning on paraffin. However, the latter needs to be confirmed in larger studies with inclusion of all EMR specimens. (Clinical trial registration number: ISRCTN50525266.).

Abstract
BACKGROUND AND OBJECTIVES Primary colonic lymphoma (PCL) is rare, heterogeneous, and presents a therapeutic challenge for surgeons. Optimal treatment strategies are difficult to standardize, leading to variation in therapy. Our objective was to describe the patient characteristics, short-term outcomes, and five-year survival of patients undergoing nonpalliative surgery for PCL. METHODS We performed a retrospective cohort analysis in the National Cancer Database. Included patients underwent surgery for PCL between 2004 to 2014. Patients with metastases and palliative operations were excluded. Univariate predictors of overall survival were analyzed using multivariable Cox proportional hazard analysis. RESULTS We identified 2153 patients. Median patient age was 68. Diffuse large B-cell lymphoma accounted for 57% of tumors. 30- and 90-Day mortality were high (5.6% and 11.1%, respectively). Thirty-nine percent of patients received adjuvant chemotherapy. For patients surviving 90 days, 5-year survival was 71.8%. Chemotherapy improved survival (surgery+chemo, 75.4% vs surgery, 68.6%; P = .01). Adjuvant chemotherapy was associated with overall survival after controlling for age, comorbidity, and lymphoma subtype (HR 1.27; 95% CI, 1.07-1.51; P = .01). CONCLUSIONS Patients undergoing surgery for PCL have high rates of margin positivity and high short-term mortality. Chemotherapy improves survival, but <50% receive it. These data suggest the opportunity for improvement of care in patients with PCL.

Abstract
BACKGROUND/AIMS We measured changes in mitochondrial function and bioenergetics that occur during ischemia/ reperfusion in fresh liver samples of patients undergoing liver transplantation. These variations correlated with markers of liver function and clinical outcome. Ischemia/reperfusion injury related to liver transplantation affects mitochondrial function and bioenergetics. Experimental studies were conducted to identify the role of bioenergetics and mitochondrial dysfunction. To the best of our knowledge, no investigation of these two factors' impacts on liver transplantation has been performed. METHODS This was a prospective study of 28 patients who underwent liver transplantation. We measured parameters of mitochondrial function and bioenergetics in biopsies performed during the procedure. RESULTS We observed a statistically significant reduction in mitochondrial membrane potential, an increase in lag phase, and decreases in mitochondrial respiration and adenosine triphosphate content (P<0.010). Higher postoperative aminotransferase peaks correlated with worse mitochondrial function; mitochondrial respiration correlated with arterial lactate (P<0.010). CONCLUSION There is a relationship between mitochondrial function and ischemia/reperfusion injury. The future use of these clinical markers as prognostic factors may allow early identification of post-transplant liver failure and may indicate the need to perform a new transplant.
