Background: In 2007, Cancer Care Ontario created Thoracic Surgical Oncology Standards for the delivery of surgery, including lobectomy, esophagectomy, and pneumonectomy. These standards regionalized thoracic surgery into designated centers and mandated physical and human resources. This analysis sought to identify the impact of these standards, hereafter referred to as "regionalization," on outcomes after thoracic oncology surgery in Ontario, Canada., Methods: This study was a population-level analysis of patients undergoing lobectomy, esophagectomy, or pneumonectomy, and it used multilevel regression models to compare 30- and 90-day mortality and length of stay before, during, and after regionalization. Interrupted time series models were used to assess for an impact of regionalization while controlling for ongoing trends., Results: A total of 22,195 surgical procedures (14,902 lobectomies, 4958 esophagectomies, and 2408 pneumonectomies) were performed within the study period. A total of >99% of cases were performed at a designated center after regionalization. Mean annual volumes per designated center increased after regionalization for lobectomy and esophagectomy and decreased for pneumonectomy. The 30- and 90-day mortality and length of stay improved for lobectomy and esophagectomy over the study period, as did 90-day mortality for pneumonectomy. However, the interrupted time series analysis did not demonstrate any statistically significant effect of regionalization on these outcomes, separate from preexisting trends., Conclusions: Consistent improvements in mortality and length of stay in thoracic surgical oncology occurred on a provincial level between 2003 and 2020, although this analysis does not attribute these improvements to implementation of Thoracic Surgical Oncology Standards including regionalization., Competing Interests: Disclosures The authors have no conflicts of interest to disclose., (Copyright © 2024 The Authors.

Background and Objectives: The combination of focused ultrasound (FUS) and chemotherapy is a novel treatment for pancreatic cancer. This paper reviews the literature on this combined therapy., Methods: The medical literature was searched according to PRISMA guidelines. Inclusion criteria were any study of patients with pancreatic cancer undergoing treatment with FUS and chemotherapy. Data extracted included stage, radiologic response, resection rate, survival, and adverse events., Results: The initial search yielded 212 citations; 10 studies met inclusion criteria (9 retrospective cohorts; 1 randomized trial). A total of 631 patients received FUS + chemotherapy; 63.6% being stage 4, and 29.7% stage 3. Patient selection, FUS parameters, and chemotherapy used were all heterogeneous. Overall survival ranged from 7.4 to 21.6 months, radiologic response rate was 44.1%, and 24.4% of stage 3 patients underwent resection. All four studies with a comparison group demonstrated improved survival. FUS + chemotherapy decreased pain in 69.7% of patients. Severe adverse events occurred in 0.65%., Conclusions: The literature on combined FUS and chemotherapy for pancreatic cancer is heterogeneous. There is good evidence that adverse events are low, and that it provides effective palliation. There is evidence to suggest oncologic benefit, however, this is subject to selection bias and prospective trials are needed., (© 2024 The Author(s).

Background: In 2006, Cancer Care Ontario created Surgical Oncology Standards for the delivery of hepatopancreatobiliary (HPB) surgery including hepatectomy and pancreaticoduodenectomy (PD). Our objective was to identify the impact of standardization on outcomes after HPB surgery in Ontario, Canada., Study Design: This study was a population-level analysis of patients undergoing hepatectomy or PD (2003 to 2019). Logistic regression models were used to compare 30- and 90-day mortality and length of stay (LOS) before (2003 to 2006), during (2007 to 2011), and after (2012 to 2019) standardization. Interrupted time series models were used to co-analyze secular trends., Results: A total of 7,904 hepatectomies and 5,238 PDs were performed. More than 80% of all cases were performed at a designated center (DC) before standardization. This increased to >98% in the poststandardization era. Median volumes at DCs increased from 55 to 67 hepatectomies/year and from 22 to 50 PDs/year over time. In addition, 30-day mortality after hepatectomy was 2.6% before standardization and 2.3% after standardization (p = 0.9); 30-day mortality after PD was 3.6% before standardization and 2.4% after standardization (p = 0.1). Multivariable analyses revealed a significant difference in 90-day mortality following PD poststandardization (4.3% vs 6.3%; adjusted odds ratio, 0.7; p = 0.03). Median LOS was shorter for hepatectomy (6 days vs 8 days) and PD (9 days vs 14 days; p < 0.0001) after standardization. Immediate and late effects on mortality and LOS were likely attributable to secular trends, which predated standardization., Conclusions: Standardization was associated with a higher volume of hepatectomy and PDs with further concentration of care at DCs. Pre-existing quality initiatives may have attenuated the effect of standardization on quality outcomes. Our data highlight the merits of a multifaceted provincial system for enabling consistent access to high quality HPB care throughout a region of 15 million people over a 16-year period., (Copyright © 2023 by the American College of Surgeons.

Objective: To examine long-term healthcare dependency outcomes of stereotactic body radiation therapy (SBRT) to surgery for older adults with stage I non-small cell lung cancer (NSCLC)., Background: SBRT is an emerging alternative to surgery in patients with early-stage lung cancer. There remains a paucity of prospective studies comparing these modalities, especially with respect to long-term dependency outcomes in older adults with lung cancer., Methods: Adults 70 years old and above with stage I NSCLC treated with surgery or SBRT from January 2010 to December 2017 were analyzed using 1:1 propensity score matching. Homecare use, days at home, and time spent alive and at home were compared. E-value methods assessed residual confounding., Results: A total of 1129 and 2570 patients underwent SBRT and surgery, respectively. In all, 1016 per group were matched. SBRT was associated with a higher overall risk of homecare utilization [hazard ratio (HR)=1.75, 95% confidence interval (CI): 1.37-2.23] than surgery up to 5 years following treatment. While the hazards of death or nursing home admission were lower in the first 3 months after SBRT (HR=0.55, 95% CI: 0.36-0.85), they became consistently higher beyond this period and remained high up to 5 years compared with surgery (HR=2.13; 95% CI: 1.85-2.45). The above findings persisted in stratified analyses for frail patients and those with no pretreatment homecare. E-values indicated it was unlikely that the observed estimates could be explained by unmeasured confounders., Conclusions: Surgery offers robust long-term dependency outcomes compared with SBRT. These are important patient-centered endpoints which may be used for counseling and shared decision-making in older adults with stage I NSCLC., Competing Interests: The authors report no conflicts of interest., (Copyright © 2022 Wolters Kluwer Health, Inc.

Objective: To conduct a population-level analysis of temporal trends and risk factors for high symptom burden in patients receiving surgery for non-small cell lung cancer (NSCLC)., Background: A population-level overview of symptoms after curative intent surgery is necessary to inform decision making and supportive care for patients with lung cancer., Methods: Retrospective cohort study of patients receiving surgery for stages I to III NSCLC between January 2007 and September 2018. Prospectively collection Edmonton Symptom Assessment System (ESAS) scores, linked to provincial administrative data, were used to describe the prevalence, trajectory, and predictors of moderate-to-severe symptoms in the year following surgery., Results: A total of 5350 patients, with 28,490 unique ESAS assessments, were included in the analysis. Moderate-to-severe tiredness (68%), poor wellbeing (63%), and shortness of breath (60%) were the most common symptoms reported. The rise and fall in the proportion of patients experiencing moderate-to-severe symptoms after surgery coincided with the median time to first (58 days, interquartile range: 47-72) and last cycle of chemotherapy (140 days, interquartile range: 118-168), respectively. There was eventual stabilization, albeit above the preoperative baseline, within 6 to 7 months after surgery. Female sex (relative risk [RR] 1.09- 1.26), lower income (RR 1.08-1.23), stage III disease (RR 1.15-1.43), adjuvant therapy (RR 1.09-1.42), chemotherapy within 2 weeks of an ESAS assessment (RR 1.14-1.73), and pneumonectomy (RR 1.05-1.15) were associated with moderate-to-severe symptoms following surgery., Conclusions: Knowledge of population-level prevalence, trajectory, and predictors of moderate-to-severe symptoms after surgery for NSCLC can be used to facilitate shared decision making and improve symptom management throughout the course of illness., Competing Interests: J.H. has received speaking honoraria from Ipsen Biopharmaceuticals Canada and Advanced Accelerator Applications.

Background: Prolonged operative duration has been associated with increased post-operative morbidity in numerous surgical subspecialties; however, data are limited in operations for colon cancer specifically and existing literature makes unwarranted methodological assumptions of linearity. We sought to assess the effects of extended operative duration on perioperative outcomes in those undergoing segmental colectomy for cancer using a methodologically sound approach., Methods: We conducted a retrospective cohort study of patients undergoing segmental colectomy for cancer between 2014 and 2018, logged in the National Surgical Quality Improvement Program datasets. Our primary outcome was a composite of any complication within 30 days; secondary outcomes included length of stay and discharge disposition. Our main factor of interest was operative duration., Results: We analyzed 26,380 segmental colectomy cases, the majority of which were approached laparoscopically (64.95%) and were right sided (62.93%). Median operative duration was 152 (95% CI 112-206) minutes. On multivariable regression, increased operative duration was linearly associated with any complication (OR = 1.003, 95% CI 1.003-1.003, p < 0.0001) in the overall cohort, as was length of stay (p < 0.0001). All subgroups except for the laparoscopic left colectomy group were linearly associated with operative duration. In the laparoscopic left colectomy group, an inflection point in the odds of any complication was found at 176 min (OR = 1.39, 95% CI 1.20-1.61, p < 0.0001)., Conclusions: This study suggests that the risk of perioperative complications increases linearly with increasing operative duration, where each additional 30 min increases the odds of complication by 10%. In those undergoing laparoscopic left colectomy, the risk of complications sharply increases after ~ 3 h, suggesting that surgeons should aim to complete these procedures within 3 h where possible., (© 2021.

Purpose: The impact of body mass index (BMI) on outcomes after open or laparoscopic surgery for rectal cancer remains unclear. The objective of this retrospective cohort study was to examine the interaction of body mass index and surgical modality (i.e., laparoscopy versus open) with respect to short-term clinical outcomes in patients with rectal cancer., Methods: The ACS-NSQIP database (2012-2016) was reviewed for patients undergoing open or laparoscopic surgery for rectal cancer. The primary outcome was 30-day all-cause morbidity. Logistic regression and Cox proportional hazard models were used for analysis., Results: A total of 16,145 patients were grouped into open (N = 6759, 42%) and laparoscopic (N  = 9386, 58%) cohorts. Patients with higher BMI (p < 0.001) and those undergoing open surgery (p < 0.001) were at increased risk of all-cause morbidity. There was no significant change in the odds ratio of experiencing all-cause morbidity between open and laparoscopic surgery with increasing BMI (p = 0.572). Median length of stay was significantly shorter in the laparoscopy group (4 days vs. 6 days; p < 0.001), at the cost of increased operative time (239 min vs. 210 min, p < 0.001). The difference in operative time between laparoscopy and open surgery did not increase with rising BMI (i.e., ∆37 min vs. ∆39 min at BMI 25 kg/m 2 vs 50 kg/m 2 , respectively, p = 0.491)., Conclusion: BMI may not be a strong modifier for surgical approach with respect to short-term clinical outcomes in patients with obesity and rectal cancer. Laparoscopic surgery was associated with improved short-term clinical outcomes, without much change in the absolute difference in operative time compared with open surgery, even at higher BMIs., (© 2021.

Background: Anastomotic leak (AL) is a common complication after colectomy with a relatively high failure to rescue rate (FTR), or death after major complications. There is emerging evidence to suggest an early AL may be associated with increased technical difficulty. Whether the timing of an AL is associated with higher FTR has not been established., Methods: Patients who underwent a colectomy between 2012 and 2017 were identified from the American College of Surgeons National Quality Improvement Program (ACS NSQIP database). The primary outcome was FTR after AL. The predictor variable used was day of post-operative leak (POD) categorized into early (POD ≤ 3), intermediate (3 < POD ≤ 20) and late (20 < POD ≤ 30) AL. These POD groups were compared to generate hypotheses to explain any association observed between timing of AL and FTR., Results: Of 135,539 identified patients, 4613 patients experienced an AL (3.4%) with an overall FTR of 6.4%. FTR differed by timing of AL: early AL was found to have a FTR of 28/195 (12.6%), with a FTR in intermediate AL of 152/2550 (5.6%) and 3/356 (0.8%) in late AL patients (p < 0.0001). When compared by timing of AL, patients differed by sex, pre-operative bowel preparation, de-functioning ostomy rates and re-operation rates (p < 0.05). Controlling for age, ASA, sex, emergency status, operative approach, indication, de-functioning ostomy, re-operation and concurrent procedure, an early AL was found to have a 2.3-fold increased risk of FTR (95% CI 1.38-3.84, p = 0.001), with a late AL having a 0.15-fold decreased risk (95% CI 0.04-0.49, p = 0.002), both compared to an intermediate AL., Conclusion: Early ALs, occurring within three days of surgery, may carry a significant risk of FTR. Given the findings identified here, this may support the use of early detection algorithms and interventions of AL to minimize the risk of FTR., (© 2021.

Objective: We describe our five-year experience with a novel co-learning curriculum in quality improvement (CCQI) 1 for the largest reported cohort of surgical residents. The program introduces trainees to principles of quality improvement (QI) 2 and empowers them to complete collaborative projects with mentorship from faculty experts., Design: Each iteration consists of three interactive seminars. Residents are required to complete and present a QI project in the third seminar. To assess the impact of the program, graduates of the 2020-2021 iteration were surveyed using validated tools to examine changes in confidence and knowledge of QI principles., Setting: Department of Surgery, University of Toronto, Toronto, ON, Canada., Participants: Participation ranged from 57 to 63 residents yearly, from diverse surgical disciplines including General Surgery, Plastic Surgery, Obstetrics and Gynecology, amongst others. Multiple small groups consisted of 4-6 residents from each speciality, mentored by a faculty lead from the same specialty., Results: Approximately 300 first-year surgical residents have participated in the CCQI since 2015, with over 60 completed QI projects. A total of 41(66%) and 51(82%) residents completed the survey in its pre- and post-course administration in 2020-2021, respectively. There was a significant increase in confidence scores with respect to describing a QI issue, building a team, and testing the change, amongst other aspects. There was also a statistically significant increase in mean knowledge scores for both scenarios of the Quality Improvement Knowledge Application Tool. 69% and 73% of residents reported "some improvement" in their knowledge, and confidence in applying QI principles to patient care, respectively. A majority of residents (73%) found the QI curriculum somewhat valuable, with 23% reporting it to be very valuable to their residency and future surgical career., Conclusions: We describe successful long-term implementation of a novel co-learning curriculum in quality improvement. Residents derive value from this curriculum with a meaningful increase in confidence and knowledge of QI as an integral part of surgical practice., (Copyright © 2021 Association of Program Directors in Surgery.

Background: Frequent emergency department (ED) visits occur after esophagectomy. We aimed to identify the incidence of and risk factors for conversion from ED visit to inpatient admission., Methods: A retrospective cohort study was performed of consecutive esophagectomies at a tertiary Canadian center (1999 to 2014). Multivariable regression analyses identified factors associated with conversion from ED visit to admission., Results: There were 520 esophagectomies with 6% inhospital mortality (n = 31). Of those discharged, 29.7% (n = 145) had one or more emergency visit and 43.4% (n = 63) of these patients were readmitted to the hospital. First-time ED visits resulted in inpatient conversion 23.4% of the time (n = 34); successive ED visits resulted in increasing conversion. On multivariable analysis, anastomotic leak (adjusted odds ratio 2.45; 95% confidence interval, 1 to 6.01; P = .05) was independently associated with higher odds of conversion to admission. Sensitivity analysis using Poisson regression to model conversion as a rate identified that living in regions further away was associated with lower conversion rate to admission (risk ratio 0.35; 95% confidence interval, 0.13 to 0.94; P = .04)., Conclusions: Although postesophagectomy ED utilization is high, the majority of visits do not convert to admission. With each increasing ED visit, likelihood of converting to admission increases. Anastomotic leakage was associated with higher odds of conversion to admission, possibly related to development of strictures. Access to urgent outpatient endoscopy may help reduce the incidence of ED visits and admission. Although living in regions further away is associated with lower conversion rates to admission at the index hospital, that may be due to patients utilizing closer local hospitals., (Copyright © 2021 The Society of Thoracic Surgeons.

Importance: Failure to rescue (FTR), or death after major complications, has emerged as a marker of hospital-level quality of care., Objective: To evaluate the predictive performance of the ACS-NSQIP modified frailty index (mFI) in determining FTR following an anastomotic leak (AL) after a colectomy for colorectal cancer., Design: Retrospective cohort study., Setting: Multicenter interrogation of the 2012-2016 American College of Surgeons (ACS) colectomy procedure targeted National Surgical Quality Improvement Program (NSQIP) database., Patients and Methods: A total of 50,944 patients who underwent colectomy for colorectal cancer., Exposure: Frailty as measured by: (1) Age, ASA, and emergency status (model 1), (2) Age, ASA, emergency status, and mFI (model 2), (3) ACS-NSQIP mortality prediction (model 3)., Main Outcome and Measure: Primary outcome was FTR after AL., Results: A total of 1755 patients experienced an AL (3.46%) with a FTR rate of 6.44%. The mean age was 65.6 years (95% CI 65.28-65.58 years), median ASA was 3 (IQR 2-3), 51 patients (2.92%) were partially or totally dependent, 366 (20.86%) were diabetic, 105 (5.98%) had a history of chronic obstructive pulmonary disease (COPD), 32 (1.82%) had a history of congestive heart disease (CHD), and 966 (55.04%) were on hypertensive treatment. The performance of model 1 (AUROC 0.77; 95% CI 0.72-0.81), model 2 (AUROC 0.77; 95% CI 0.73-0.82), and model 3 (AUROC 0.79; 95% CI 0.75-0.83) to predict FTR was not different (p = 0.44)., Conclusions and Relevance: Age and ASA remain the most reliable predictors of failure to rescue anastomotic leak after colectomy for colorectal cancer. Addition of the modified frailty index, or all variables collected by NSQIP, did not significantly improve predictive performance.

Background: Technical and clinical differences in resection of obstructed and non-obstructed colon cancers may result in differences in lymph node retrieval. The objective of this study is to compare the lymph node harvest following resection of obstructed and nonobstructed colon cancer patients., Methods: A retrospective analysis utilizing the 2014-2018 NSQIP colectomy targeted data set was conducted. One-to-one coarsened exact matching (CEM) was utilized between patients undergoing resection for obstructed and non-obstructed colon cancer. The primary outcome was the adequacy of lymph node retrieval (LNR, ≥12 nodes)., Results: CEM resulted in 9412 patients. Patients with obstructed tumors were more likely to have inadequate LNR (13.3% vs 8.2%, p < .001) compared to those with nonobstructed tumors. Multivariate analysis demonstrated that patients with obstructing tumors had worse LNR compared to non-obstructed tumors (odds ratio [OR]: 0.74, 95% confidence interval [CI]: 0.62-0.87; p < .005). Increased age (OR: 0.99, 95% CI: 0.098-0.99), presence of preoperative sepsis (OR: 0.70, 95% CI: 0.055-0.90), left-sided and sigmoid tumors compared to right-sided (OR: 0.64, 95% CI: 0.51-0.81; OR: 0.69, 95% CI: 0.58-0.82, respectively), and open surgical resection compared to an minimally invasive surgical approach were associated with inadequate LNR (p < .05)., Conclusion: This study demonstrated that resection for obstructing colon cancer compared to non-obstructed colon cancer is associated with increased odds of inadequate lymph node harvest., (© 2020 Wiley Periodicals LLC.)

Objective: To determine if Black race is associated with worse short-term postoperative morbidity and mortality when compared to White race in a contemporary, cross-specialty-matched cohort., Background: Growing evidence suggests poorer outcomes for Black patients undergoing surgery., Methods: A retrospective analysis was conducted comprising of all patients undergoing surgery in the National Surgical Quality Improvement Program dataset between 2012 and 2018. One-to-one coarsened exact matching was conducted between Black and White patients. Primary outcome was rate of 30-day morbidity and mortality., Results: After 1:1 matching, 615,118 patients were identified. Black race was associated with increased rate of all-cause morbidity (odds ratio [OR] = 1.10, 95% confidence interval [CI] 1.08-1.13, P < 0.001) and mortality (OR = 1.15, 95% CI 1.01-1.31, P = 0.039). Black race was associated with increased risk of re-intubation (OR = 1.33, 95% CI 1.21-1.48, P < 0.001), pulmonary embolism (OR = 1.55, 95% CI 1.40-1.71, P < 0.001), failure to wean from ventilator for >48 hours (OR = 1.14, 95% CI 1.02-1.29, P < 0.001), progressive renal insufficiency (OR = 1.63, 95% CI 1.43-1.86, P < 0.001), acute renal failure (OR = 1.39, 95% CI 1.16-1.66, P < 0.001), cardiac arrest (OR = 1.47, 95% CI 1.24-1.76 P < 0.001), bleeding requiring transfusion (OR = 1.39, 95% CI 1.34-1.43, P < 0.001), DVT/thrombophlebitis (OR = 1.24, 95% CI 1.14-1.35, P < 0.001), and sepsis/septic shock (OR = 1.09, 95% CI 1.03-1.15, P < 0.001). Black patients were also more likely to have a readmission (OR = 1.12, 95% CI 1.10-1.16, P < 0.001), discharge to a rehabilitation center (OR = 1.73, 95% CI 1.66-1.80, P < 0.001) or facility other than home (OR = 1.20, 95% CI 1.16-1.23, P < 0.001)., Conclusion and Relevance: This contemporary matched analysis demonstrates an association with increased morbidity, mortality, and readmissions for Black patients across surgical procedures and specialties., Competing Interests: Disclosure: The authors declare that they have nothing to disclose., (Copyright © 2020 The Author(s).

Patient reported outcomes (PROs) fulfill a crucial and unique niche in patient management, providing health-care providers a glimpse into their patients' health experience. This is of utmost importance in patients with benign and malignant disorders of esophagus requiring surgery, which carries significant morbidity, in part due to a high burden of symptoms affecting health-related quality of life (HRQOL). There are a variety of generic and disease-specific patient reported outcome measures (PROMs) available for use in esophageal surgery. This article provides a broad overview of commonly used HRQOL instruments in esophageal surgery, including their utility in comparative effectiveness research, prognostication and shared decision-making for patients undergoing surgery for benign and malignant disorders of the esophagus., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at http://dx.doi.org/10.21037/jtd.2020.03.58).

Summary: The coronavirus disease 2019 (COVID-19) pandemic has accentuated the importance of leadership training for health care professionals, particularly surgeons. Surgeons are expected to lead and thrive in multidisciplinary teams. There is, however, a critical gap in teaching residents about fundamental leadership principles, such as developing productive and vision-driven teams, conflict resolution and emotional intelligence. We discuss the merits of leadership training for surgical residents and future directions for implementing a leadership curriculum for Canadian residency programs in the competency by design era., Competing Interests: None declared., (© 2020 Joule Inc. or its licensors.)

Objectives: Lung cancer is associated with significant disease- and treatment-related morbidity. The Edmonton Symptom Assessment System (ESAS) is a tool developed to elicit patients' own assessment of the severity of common cancer-associated symptoms. The objective of this study was to examine symptom severity in the 12 months following diagnosis of lung cancer, and to identify predictors of high symptom burden., Materials and Methods: This was a retrospective population-based cohort study, including patients with stage I-III lung cancer diagnosed between 2007-2016, and who had symptom screening in the 12 months following diagnosis. The proportion of patients reporting severe symptoms (ESAS ≥ 7) in the year following diagnosis was plotted over time. Multivariable regression models were constructed to identify factors associated with severe symptoms., Results: 69,440 unique symptom assessments were reported by 11,075 lung cancer patients. Tiredness was the most prevalent severe symptom (47.3 %), followed by shortness of breath (39.4 %) and poor wellbeing (36.5 %) among all disease stages. Patients diagnosed with higher stage disease reported more severe symptoms, but symptom trajectories were similar for all stages in the year following diagnosis. Disease stage (RR 1.10-2.01), comorbidity burden (RR 1.17-1.51), degree of socioeconomic marginalization (RR1.15-1.45), and female sex (RR 1.15-1.50) were associated with reporting severe symptoms in the year following diagnosis., Conclusion: Severe physical and psychological symptoms persist throughout the first year following lung cancer diagnosis, regardless of disease stage. Those at risk of experiencing high symptom burden may benefit from targeted supportive care interventions, including psychosocial support aimed at improving health-related quality of life., Competing Interests: Declaration of Competing Interest NGC has received salary support from Cancer Care Ontario as the Clinical Lead of Patient Reported Outcomes and Symptom Management.

Background: There is growing enthusiasm for robotic and transanal surgery as an alternative to open or laparoscopic surgery for colorectal cancer (CRC). We examined the impact of surgical modality on body image and quality of life (QOL) in patients receiving anterior resection for CRC., Methods: We used a mixed-methods approach, consisting of a chart review and semistructured interviews with CRC patients, at least 8 months after surgery. We assessed cosmetic outcomes and QOL using validated questionnaires., Results: Thirty patients were stratified into open (n = 8), laparoscopic (n = 12) and robotic (n = 10) groups. Mean body image scores were significantly higher (i.e., poorer body image) in patients receiving open surgery (mean difference [MD] +5.7 with laparoscopy, p < 0.001). Open surgery was more detrimental to physical function, including strenuous activities, prolonged ambulation and self-care (MD –11.6 with laparoscopy, p = 0.039). Patients receiving laparoscopic surgery reported superior role (MD +27.6 with open surgery, p = 0.002) and social function (MD +13.7 with open surgery, p = 0.042), including the ability to enjoy hobbies, family life and social activities. Surgical modality did not impact emotional and cognitive function or symptoms including genitourinary function, pain and defecation., Conclusion: The negative impact of open surgery on body image and physical function warrants further educational interventions for patients. The protective effect of laparoscopy on role and function may be associated with “tumour factors” that are unaccounted for in the European Organization for Research and Treatment of Cancer questionnaires. Open surgery is detrimental to body image and physical function in patients receiving anterior resection for CRC. Prospective randomized studies are required to validate these findings., Competing Interests: None declared., (© 2019 Joule Inc. or its licensors)

Background: Frailty assessment has not been thoroughly assessed in thoracic surgery. Our primary objective was to assess the feasibility of comprehensive frailty testing prior to lung and esophageal surgery for cancer. The secondary objective was to assess the utility of frailty indices in risk assessment prior to thoracic surgery., Methods: Prospectively recruited patients completed multiple physiotherapy tests (6-min walk, gait speed, hand-grip strength), risk stratification (Charlson Comorbidity Index, Revised Cardiac Risk Index, Modified Frailty Index), and quality of life questionnaires. Lean psoas area was also assessed by a radiologist using positron emission tomography/computed tomography scans. Data was analyzed using Fisher's exact, Mann-Whitney U and independent t tests., Results: The feasibility of comprehensive frailty assessment was assessed over a 4-month period among 40 patients (esophagus n = 20; lung n = 20). Risk stratification questionnaires administered in clinic had 100% completion rates. Physiotherapy testing required a trained physiotherapist and an additional visit to the pre-admission clinic; these tests proved difficult to coordinate and had lower completion rates (63-75%). Although most measures were not significantly associated with occurrence of complications, the Modified Frailty Index approached statistical significance (p = 0.06)., Conclusions: Frailty assessment is feasible in the pre-operative outpatient setting and had a high degree of acceptance among surgeons and patients. Of the risk stratification questionnaires, the Modified Frailty Index may be useful in predicting outcomes as per this feasibility study. Pre-operative frailty assessment can identify vulnerable oncology patients to aid in treatment planning with the goal of optimizing clinical outcomes and resource allocation.

Carcinomas of the lung and esophagus are associated with significant disease and treatment related morbidity. Measuring patients' self-perceived notion of their health-related quality of life (HRQOL), throughout the course of illness, is central to the delivery of comprehensive, patient-centered care. This article reviews commonly used HRQOL instruments in thoracic surgery and discusses the integral role of patient-reported outcomes (PROs) in comparative effectiveness research and prognostication in the realm of lung and esophageal cancer. We also highlight challenges and future directions for widespread implementation of PROs into clinical and research practice., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare.

Background: Several modalities exist for the management of hepatic neoplasms. Resection, the most effective approach, carries significant risk of hemorrhage. Blood loss may be corrected with red blood cell transfusion (RBCT) in the short term, but may ultimately contribute to negative outcomes., Purpose: Using available literature, we seek to define the frequency and risk factors of blood loss and transfusion following hepatectomy. The impact of blood loss and RBCT on short- and long-term outcomes is explored with an emphasis on peri-operative methods to reduce hemorrhage and transfusion., Results: Following hepatic surgery, 25.2-56.8% of patients receive RBCT. Patients who receive RBCT are at increased risk of surgical morbidity in a dose-dependent manner. The relationship between blood transfusion and surgical mortality is less apparent. RBCT might also impact long-term oncologic outcomes including disease recurrence and overall survival. Risk factors for bleeding and blood transfusion include hemoglobin concentration < 12.5 g/dL, thrombocytopenia, pre-operative biliary drainage, presence of background liver disease (such as cirrhosis), coronary artery disease, male gender, tumor characteristics (type, size, location, presence of vascular involvement), extent of hepatectomy, concomitant extrahepatic organ resection, and operative time. Strategies to mitigate blood loss or transfusion include pre-operative (iron, erythropoietin), intra-operative (vascular occlusion, parenchymal transection techniques, hemostatic agents, antifibrinolytics, low central pressure, hemodilution, autologous blood recycling), and post-operative (normothermia, correction of coagulopathy, optimization of nutrition, restrictive transfusion strategy) methods., Conclusion: Blood loss during hepatectomy is common and several risk factors can be identified pre-operatively. Blood loss and RBCT during hepatectomy is associated with post-operative morbidity and mortality. Disease-free recurrence, disease-specific survival, and overall survival may be associated with blood loss and RBCT during hepatectomy. Attention to pre-operative, intra-operative, and post-operative strategies to reduce blood loss and RBCT is necessary.

Objectives: Esophagectomy is a complex operation with potential for prolonged recovery. We aimed to identify the incidence of and risk factors for any and frequent emergency department visits within 1 year of esophagectomy., Methods: A retrospective cohort study was performed looking at consecutive esophagectomies at a tertiary Canadian center (1999-2014). Multivariable analyses identified factors associated with any emergency department visits and frequent emergency department use (≥3 visits) within 1 year postesophagectomy., Results: There were 520 esophagectomies with in-hospital mortality of 6% (n = 31). Of those discharged, 29.7% (n = 145) had ≥ 1 emergency department visit. Most common causes were feeding tube problems (39.3%; n = 57) and dysphagia/stricture (13.1%; n = 19). Higher income (adjusted odds ratio [aOR], 1.22; 95% confidence interval [CI], 1.04-1.42 per $10,000) and use of hybrid/minimally invasive esophagectomy (aOR, 3.24; 95% CI, 1.71-6.11) were independently associated with having emergency department visits. Patients with hybrid/minimally invasive esophagectomy were discharged earlier than others (P < .0001). Living outside of our metropolitan area (aOR, 0.36; 95% CI, 0.27-0.49) and having surgery in the later years of the study period (aOR, 0.91; 95% CI, 0.86-0.97; P = .006) were both independently associated with lower odds of emergency department visits. Forty-three patients (8.8%) were frequent emergency department users, with the most common causes of repeat emergency visits being feeding tube problems. Living outside of our metropolitan area was associated with lower odds of frequent emergency visits (aOR, 0.25; 95% CI, 0.14-0.45)., Conclusions: There is high emergency department use within 1 year postesophagectomy. Patients living farther away from our hospital had a lower rate of emergency department use. It is possible that they are utilizing emergency departments nearer to home; this needs further study. Feeding tube problems are the biggest culprits and are potentially modifiable., (Copyright © 2018. Published by Elsevier Inc.)

Background: Simultaneous resection for colorectal cancer with synchronous liver metastases is an established alternative to a staged approach. This study aimed to compare these approaches with regards to economic parameters and short-term outcomes., Methods: A retrospective cohort analysis was conducted between 2005 and 2016. The primary outcome was cost per episode of care. Secondary measures included 30-day clinical outcomes. A multivariate analysis was performed to determine the adjusted effect of a simultaneous surgical approach on total cost of care., Results: Fifty-three cases were identified; 27 in the staged approach, and 26 in the simultaneous group. Age (P = 0.49), sex (P = 0.20), BMI (P = 0.74), and ASA class (P = 0.44) were comparable between groups. Total cost ($20297 vs $27522), OR ($6830 vs $10376), PACU ($675 vs $1182), ward ($7586 vs $11603) and pharmacy costs ($728 vs $1075) were significantly less for the simultaneous group (P < 0.05). The adjusted rate ratio for total cost of care in the staged group compared to simultaneous group was 1.51 (95%CI: 1.16-1.97, P < 0.05). The groups had comparable Clavien-Dindo scores (P = 0.89), 30-day readmissions (P = 0.44), morbidity (P = 0.50) and mortality (P = 1.00)., Conclusions: Our study demonstrates that a simultaneous approach is associated with a significantly lower total cost while maintaining comparable short-term outcomes., (© 2018 Wiley Periodicals, Inc.)

Purpose: To report the use of a balloon catheter to facilitate percutaneous ultrasound-guided thrombin injection of a subclavian artery pseudoaneurysm., Case Report: A 36-year-old man presented with hoarseness after the insertion of a right temporary internal jugular line. Arteriography showed a short neck right subclavian artery pseudoaneurysm. A 6 mm × 40 mm balloon catheter was positioned across the neck of the pseudoaneurysm to permit percutaneous ultrasound-guided thrombin injection. Immediate post-treatment angiogram demonstrated no filling of the pseudoaneurysm. Seven-month clinical and imaging follow-up confirmed resolution of the pseudoaneurysm and hoarseness., Conclusions: This clinical vignette highlights the potential of balloon catheter-assisted percutaneous ultrasound-guided thrombin injection as an alternative to open or endovascular repair of pseudoaneurysms of the subclavian arteries.

Background: The objective of this study was to assess Canadian general surgeons' knowledge of bariatric surgery and perceived availability of resources to manage bariatric surgery patients., Methods: A self-administered questionnaire was developed using a focus group of general surgeons. The questionnaire was distributed at two large general surgery conferences in September and November 2012. The survey was also disseminated via membership association electronic newsletters in November and December 2012., Results: One hundred sixty-seven questionnaires were completed (104 practicing surgeons, 63 general surgery trainees). Twenty respondents were bariatric surgeons. Among 84 non-bariatric surgeons, 68.3 % referred a patient in the last year for bariatric surgery, 79 % agreed that bariatric surgery resulted in sustained weight loss, and 81.7 % would consider referring a family member. Knowledge gaps were identified in estimates of mortality and morbidity associated with bariatric procedures. The majority of surgeons surveyed have encountered patients with complications from bariatric surgery in the last year. Over 50 % of surgeons who do not perform bariatric procedures reported not feeling confident to manage complications, 35.4 % reported having adequate resources and equipment to manage morbidly obese patients, and few are able to transfer patients to a bariatric center. Of the respondents, 73.3 % reported residency training provided inadequate exposure to bariatric surgery, and 85.3 % felt that additional continuing medical education resources would be useful., Conclusions: There appears to be support for bariatric surgery among Canadian general surgeons participating in this survey. Knowledge gaps identified indicate the need for more education and resources to support general surgeons managing bariatric surgical patients.

Background: Decisions leading up to surgery are fraught with uncertainty owing to trade-offs between treatment effectiveness and quality of life. Past studies on shared decision-making (SDM) have focused on the physician-patient encounter, with little emphasis on familial and cultural factors. The literature is scarce in surgical oncology, with few studies using qualitative interviews. Our objective was to explore the complexities of SDM within the setting of colorectal cancer (CRC) surgery., Methods: An interdisciplinary team developed a semistructured questionnaire. Telephone interviews were conducted with CRC patients in the practice of 1 surgical oncologist. Data saturation was achieved and a descriptive thematic analysis was performed., Results: We interviewed 20 patients before achieving data saturation. Three major themes emerged. First, family was considered as a crucial adjunct to the patient-provider dyad. Second, patients identified several facilitators to SDM, including a robust social support system and a competent surgical team. Although language was a perceived barrier, there was no difference in level of involvement in care between patients who spoke English fluently and those who did not. Finally, patients perceived a lack of choice and control in decision-making, thus challenging the very notion of SDM., Conclusion: Surgeons must learn to appreciate the role of family as a vital addition to the patient-provider dyad. Family engagement is crucial for CRC patients, particularly those undergoing surgical resection of late-stage disease. Surgeons must be aware of the uniqueness of decision-making in this context to empower patients and families.
