The impact of comorbidities on post-operative complications following colorectal cancer surgery

Impact of age and comorbidities on colorectal endoscopic submucosal dissection outcomes: Large multicenter study in a Western cohort

Background and study aims

Endoscopic submucosal dissection (ESD) has emerged as the standard treatment for colorectal lesions. Considering aging of the global population, we aimed to assess effectiveness and safety of colorectal ESD in patients aged ≥ 80 years compared with those aged 65 to 79 years in a large Western cohort.

Patients and methods

We retrospectively enrolled patients aged > 64 years undergoing colorectal ESD, classifying them into a very elderly group (VE-Group, aged > 80 years) and elderly group (E-Group, 65-79 years). Procedure outcomes and safety were compared between the VE-Group and E-Group and between patients with comorbidities and those who were healthy (1-CM-Group and H-Group).

Results

A total of 980 patients were included (269; 27.5% in the VE-Group and 711; 72.5% in the E-Group). En-bloc, R0, and oncological curative resection rates did not differ, nor did intra-procedure or post-procedure adverse events (AEs). Delirium occurrence was registered in VE-group [6 (2.2%) in VE-Group vs 1 (0.1%) in E-Group; P = 0.001; OR = 16.2, (95%CI:1.9-135.2)]. The 1-CM-Group had a higher rate of intra-procedure bleeding ( P = 0.001), delayed perforation ( P = 0.03), fever onset ( P < 0.001), and systemic infections ( P = 0.02) compared with the H-Group. Having one or more comorbidities was associated with increased overall AEs ( P < 0.001; OR 2.3, 95% CI 1.5-3.6).

Conclusions

Colorectal ESD is feasible in elderly patients. Physicians should consider delirium a possible AE in patients older than age 80 years. These findings, which bridge the gap between Asian and Western clinical data, underscore the importance of tailored pre-procedure and post-procedure assessments in a global clinical context.

Risk Factors in Elective Colon Surgery for the Elderly: A Retrospective Cohort Analysis From the Swedish Part of the International ERAS Database

BACKGROUND

The growing proportion of older individuals worldwide is anticipated to lead to an increase in the number of elderly patients requiring surgery for colon cancer. Consequently, it is crucial to identify specific risk factors for mortality and complications after colon surgery in this age group.

METHODS

The Swedish part of the ERAS registry (EIAS) between 2009 and 2022 was used. Patients aged ≥ 75 years undergoing colon surgery were compared with younger patients regarding risk factors for severe complications and mortality after multivariate regression analysis.

RESULTS

After adjusting for potential confounders, three risk factors specifically associated with severe complications in elderly patients were identified: severe pulmonary disease (OR 1.64; 95% CI 1.04-2.58), recent immunosuppressive treatment (OR 1.92; 95% CI 1.12-3.30), and left hemicolectomy (OR 1.43; 95% CI 1.04-1.97). Furthermore, four risk factors for mortality, statistically significant only in the older age group, were found: male sex (OR 1.73; 95% CI 1.08-2.76), ASA ≥ 3 (OR 2.92; 95% CI 1.66-5.15), severe pulmonary disease (OR 2.28; 95% CI 1.02-5.06), and open surgery (OR 1.68; 95% CI 1.04-2.73).

CONCLUSION

Several risk factors for severe complications and 30-day mortality specific to the elderly group were identified. Among these, severe pulmonary disease was associated with both severe complications and mortality.

The effect of comprehensive geriatric assessment on treatment decisions, supportive care received, and postoperative outcomes in older adults with cancer undergoing surgery: A systematic review

INTRODUCTION

Surgery is an essential part of cancer treatment, particularly for localised solid tumours. Geriatric assessments (GA) with tailored interventions or comprehensive GA (CGA) can identify frailty factors and needs of older adults with cancer, assisting treatment decisions and care strategies to reduce postoperative complications. This systematic review summarises the effects of GA/CGA compared to usual care for older adults with cancer intended for surgery: their impact on treatment decisions, supportive care interventions, postoperative complications, survival, and health-related quality of life (HRQOL).

MATERIALS AND METHODS

We conducted a systematic search of MEDLINE, EMBASE, CINAHL, and PubMed (January 2000-October 2022) for randomised controlled trials (RCTs) or cohort studies with a comparison group on the effects of GA/CGA in older adults with cancer (≥65 years) intended for surgery. This systematic review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Due to heterogeneity in study designs and reporting, a meta-analysis was not possible; results are narratively described.

RESULTS

From 12,440 citations, 312 were selected for full-text review. Thirteen studies reporting on 12 trials were included for analysis: four RCTs and eight cohort studies with comparison groups (three prospective, five retrospective). RCTs ranged in sample size (122-475; mean 249), with variability in who performed GA/CGA, disciplines involved, and team integration. Primary outcomes included impact of GA/CGA on postoperative delirium (two studies), Clavien-Dindo (CD) grade II-V postoperative complications (one study), hospital length of stay (one study), and a composite criterion including mortality, functional impairment, and weight loss (one study). All RCTs scored high for risk of bias due to underpowering for their primary outcome; none met their primary endpoint. After adjustment for prespecified factors in secondary analyses, one RCT found GA/CGA significantly reduced the odds of postoperative complications (CD grade I-V) (adjusted-OR: 0.33, 95 %CI: 0.11-0.95; p = 0.05) due to fewer grade I-II complications. One RCT reported no significant difference between groups in HRQOL: intervention patients reported less pain at discharge, but this difference disappeared at three-month follow-up.

DISCUSSION

Well-powered, high-quality trials are needed to determine the impact of GA/CGA on optimising surgical treatment decisions, supportive care and postoperative outcomes for older adults with cancer.

Does surgeon or hospital volume influence outcome in dedicated colorectal units?-A Viennese perspective

OBJECTIVE

A clear relationship between higher surgeon volume and improved outcomes has not been convincingly established in rectal cancer surgery. The aim of this study was to evaluate the impact of individual surgeon's caseload and hospital volume on perioperative outcome.

METHODS

We retrospectively analyzed 336 consecutive patients undergoing oncological resection for rectal cancer at two Viennese hospitals between 1 January 2015 and 31 December 2020. The effect of baseline characteristics as well as surgeons' caseloads (low volume: 0-5 cases per year, high volume > 5 cases per year) on postoperative complication rates (Clavien-Dindo Classification groups of < 3 and ≥ 3) were evaluated.

RESULTS

No differences in baseline characteristics were found between centers in terms of sex, smoking status, or comorbidities of patients. Interestingly, only 14.7% of surgeons met the criteria to be classified as high-volume surgeons, while accounting for 66.3% of all operations. There was a significant difference in outcomes depending on the treating center in univariate and multivariate binary logistic regression analysis (odds ratio (OR) = 2.403, p = 0.008). Open surgery was associated with lower complication rates than minimally invasive approaches in univariate analysis (OR = 0.417, p = 0.003, 95%CI = 0.232-0.739) but not multivariate analysis. This indicated that the center's policy rather than surgeon volume or mode of surgery impact on postoperative outcomes.

CONCLUSION

Treating center standards impacted on outcome, while individual caseload of surgeons or mode of surgery did not independently affect complication rates in this analysis. The majority of rectal cancer resections are performed by a small number of surgeons in Viennese hospitals.

How aging may impact the failure to rescue after colorectal laparoscopic surgery. Analysis of 1000 patients in a single high-volume center

This study aimed to evaluate the FTR after laparoscopic colorectal surgery in an Italian high-volume centre. A retrospective analysis was conducted in a consecutive series of patients who underwent elective laparoscopic colorectal surgery for neoplastic disease between January 2010 and December 2023 at the General Surgery Department of the San Eugenio Hospital, Rome, Italy. Patients were grouped by age in adult (vs. < 75 years) and elderly group (≥ 75 years). A multivariate analysis of the predictive factors of complications was performed. A total of 1,000 patients met the inclusion criteria, excluding those who underwent open or robotic surgery, either in emergency or elective settings. 53 patients (5.3%) experienced major complications. The mean age of patients with no or mild complications was 65.60 years (± 10.61), whereas patients with severe complications were older (69.94 years ± 12.02, p = 0.0041). Gender distribution and BMI do not represent a risk factor for major complications (p = 0.2555 and p = 0.2686, respectively), unlike the ASA score III or IV (p = 0.0001). The overall FTR rate for adult patients is 9%, while it is slightly higher at 10% for elderly patients. No statistical differences were found between the 2 groups. Elderly patients had more frequent FTR due to infective complications, while the FTR rate for cardiovascular disease was more frequent in the adult group. Minimally invasive approach, skilled team, well-established rapid response and standardized complication management protocols can positively impact FTR regardless of patients' age.

Accuracy of the "Timed Up and Go" Test for Predicting Low Muscle Mass in a Preoperative Prehabilitation Program for Colorectal Cancer

Background: Preoperative sarcopenia is associated with increased morbidity and mortality in patients undergoing colorectal cancer (CRC) surgery. The assessment of muscle mass is crucial in identifying at-risk patients, but standard imaging methods like computed tomography (CT) scans require significant resources. Functional tests, such as the Timed Up and Go (TUG) test, may serve as simple and effective alternatives for sarcopenia screening. Objective: To evaluate the accuracy of the TUG test in predicting preoperative sarcopenia in patients scheduled for CRC surgery. Methods: A prospective observational study was conducted at a tertiary colorectal unit from January 2022 to June 2023. Patients underwent a prehabilitation assessment, including the TUG test, four weeks before surgery. Sarcopenia was diagnosed based on reduced muscle mass measured at the third lumbar vertebra on CT images. Statistical analyses included the sensitivity, specificity, and overall accuracy of the TUG test in predicting sarcopenia. Results: The study included 199 CRC patients (58.3% male, mean age 71.76 ± 10.42 years). Sarcopenia was present in 48.7% of patients. The mean TUG test length was 12.52 ± 7.95 s. A TUG test time of ≥10.19 s predicted sarcopenia with 70.1% sensitivity, 75.5% specificity, and an overall accuracy of 72.9% (95% CI = 0.660-0.790). Conclusions: The TUG test is a reliable, simple, and non-invasive tool for identifying sarcopenia in patients scheduled for colorectal cancer surgery, reducing reliance on CT scans. Early detection allows for timely interventions, improving surgical outcomes and overall patient prognosis.

Timing and morbidity of loop ileostomy closure after rectal cancer resection: a prospective observational multicentre snapshot study from Multidisciplinary Italian Study group for STOmas (MISSTO)

PURPOSE

Time to closure and morbidity are significant issues associated with ileostomy reversal after rectal cancer resection. This study aimed to investigate the rate, time, and morbidity associated with ileostomy closure procedure.

METHODS

Between February and December 2022, patients who underwent protective ileostomy after rectal cancer surgery across 45 Italian surgical centres were prospectively included. Data on ileostomy closure times, surgical methods, and complications were collected and analyzed. Both univariate and multivariate statistical tests were employed to assess stoma closure rates and the occurrence of post-operative complications.

RESULTS

A total of 287 patients participated in the study. Ileostomy closure was achieved in 241 patients, yielding overall and 6-month closure rates of 84% and 62%, respectively. The median time for ileostomy closure was 146 days. Direct sutures were used to close approximately 70% of skin defects, while purse-string sutures were applied in around 20%. The overall morbidity rate was 17%, with complications including skin suture dehiscence (7%), small bowel obstruction (6%), and anastomotic leakage (2%). Multivariate analysis revealed that an American Society of Anesthesiologists (ASA) score > 2 (p = 0.028), advanced age (p = 0.048), and previous stoma complications (p = 0.048) were independently linked to failure of stoma closure; hypertension (p = 0.036) was found to be a significant independent risk factor for post-operative complications.

CONCLUSION

This study demonstrated that a delay and a significant no-closure rate exist in ileostomy reversal after rectal cancer surgery. Post-operative complications remain high but can be prevented with adequate pre-operative assessment and post-operative care.

Medication Management of Patients With Cancer Undergoing Surgery From Preadmission to Discharge: A Mixed-Methods Systematic Review

AIM(S)

To identify and synthesise available evidence about regular medication management processes, from preadmission to discharge from hospital, in patients with cancer undergoing surgery.

DESIGN

Mixed-methods systematic review.

METHODS

Studies published from inception of each database until February 2023 were screened, utilising four main search concepts. The JBI methodology for mixed-methods systematic review was followed in this review.

DATA SOURCES

MEDLINE, CINAHL, EMBASE, APA PsycINFO, Scopus and Web of Science.

RESULTS

Eight out of 717 screened studies were included. Two themes related to patients' medication management were identified. Preoperative factors such as polypharmacy, potentially inappropriate medications, delirium-inducing medications and preoperative discontinuation-requiring medications were associated with several postoperative complications in patients with cancer. Additionally, pharmacist-led interventions and collaborative efforts between nurses and patients were shown to improve the medication management process across the perioperative pathway.

CONCLUSION

This systematic review emphasises the necessity of effectively managing regular medication, especially before surgery, to mitigate postoperative complications in patients with cancer. It offers critical insights into how involving pharmacists and nurses enhances medication management outcomes, benefiting health care professionals and institutions aiming to optimise perioperative medication therapy.

IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE

Enhancing patients' regular medication management through comprehensive reviews before surgery, and improving collaborative practices among pharmacists, nurses and patients via targeted interventions introduced by health care organisations, ensure safe medication use throughout the perioperative pathway.

IMPACT

Improving regular medication management process can reduce risk of medication errors and adverse drug events and enhance postoperative outcomes.

Surgery for colorectal cancer in people aged 80 years or older - complications, risks, and outcomes

The number of older adult patients with colorectal cancer (CRC) is steadily increasing with the increasing aging population. However, healthcare professionals continue to approach treatment in older adult patients while considering the potential coexistence of complications relative to their age. There is a tendency to define and limit treatment options for managing "older adult patients" at relatively younger ages. Given the progression of aging societies and aging of patients with CRC, the impact of age on post-surgical outcomes should be analyzed to guide treatment decisions and ensure the highest quality of care for this population. This study aimed to compare outcomes in patients aged approximately 80 years who have undergone surgery after being diagnosed with CRC at the National Pusan University Hospital. This retrospective observational study included 502 patients who underwent surgery after being diagnosed with CRC at Pusan National University Hospital from January 2018 to December 2022. All surgeries were performed by a single surgeon. Older adult patients underwent open surgery more frequently. No significant differences in surgical outcomes or hospital stay were found between the two groups. Moreover, no notable differences were observed in overall complications, including major surgery-related complications such as anastomotic leakage, bleeding, and infection, between the two groups. However, pneumonia was significantly more common in the older patient group (P = .016). Among patients requiring emergency surgery, the older adult group demonstrated a significantly higher proportion of emergency surgeries and complications associated with regular surgeries compared with the younger group. In older adult patients, the risk of postoperative complications should not be determined solely based on age; a comprehensive assessment is necessary. However, in the case of emergency surgery, older adult patients may be relatively vulnerable compared with younger patients.

Prevalence of cancer-related fatigue syndrome and its association with sociodemographic and clinical characteristics in adult patients with colorectal cancer: a cross-sectional study

PURPOSE

To describe the prevalence of fatigue in adults with colorectal cancer (CRC). Additionally, to explore the associations and correlations between fatigue and sociodemographic and clinical characteristics.

METHODS

Patients with CRC at various phases of the disease were evaluated for fatigue using the Brief Fatigue Inventory (BFI), independence in activities of daily living using the Barthel index, perception of pain using the Visual Analogue Scale (VAS), and performance status using the Eastern Cooperative Oncology Group criteria in a Chilean public hospital. Descriptive analyses were used to describe the variables. Chi-square and Spearman tests were utilized to evaluate associations between fatigue and other variables.

RESULTS

Among 241 patients participate (mean age 68.9 ± 12.2 years) and colon cancer was most common (66.4%). Fatigue was present in all disease phases, with moderate fatigue most prevalent (49.3%), followed by mild (24.2%) and severe (13.6%). Newly diagnosed patients had a higher proportion of severe fatigue (p = 0.04). Women experienced more moderate fatigue than men (p < 0.05). Patients with over three comorbidities and severe pain had higher severe fatigue (p < 0.05). Mood disorders were linked to more severe fatigue, while their absence was related to milder fatigue (p = 0.02). Musculoskeletal disorders correlated with moderate fatigue, while their absence correlated with mild fatigue (p < 0.01). Small positive correlations existed between fatigue and age (Rho = 0.15) and pain (Rho = 0.23) (p < 0.05).

CONCLUSION

Cancer-related fatigue (CRF) is highly prevalent in individuals with CRC and can be present throughout all phases of the disease. Early screening and management are recommended, prior to surgical treatment.

Analyzing postoperative complications in colorectal cancer surgery: a systematic review enhanced by artificial intelligence

INTRODUCTION

Colorectal cancer stands as a predominant cause of cancer-related mortality worldwide. Despite progressive strides in surgical methodologies, the specter of postoperative complications is very large, significantly impacting both morbidity and mortality rates. This review aims to meticulously examine existing scholarly works to gauge the prevalence, severity, and therapeutic approaches to postoperative complications arising from colorectal cancer surgeries.

METHODS

Employing a systematic approach, this study reviewed 135 peer-reviewed publications from the period of 2000-2023. The corpus was organized into categories reflective of the postoperative complications discussed: anastomotic leakage, port-site metastases, small bowel adhesions and obstructions, thrombosis, ileus, postoperative infections, urinary dysfunctions, and cardiovascular dysfunctions. Advanced artificial intelligence tools were leveraged for in-depth literature searches and semantic analyses to pinpoint research lacunae.

RESULTS

The analysis revealed that anastomotic leakage and postoperative infections garnered the majority of academic focus, representing 35% and 25% of the studies, respectively. Conversely, port-site metastases and cardiovascular dysfunctions were less frequently examined, accounting for merely 5% and 3% of the literature. The reviewed studies indicate a disparity in the reported prevalence rates of each complication, oscillating between 3% and 20%. Furthermore, the review identified a dearth of evidence-based management protocols, underscored by a pronounced heterogeneity in treatment guidelines.

CONCLUSIONS

The literature is replete with analyses on anastomotic leakage and postoperative infections; however, there exists a glaring scarcity of exhaustive research on other postoperative complications. This review emphasizes the pressing need for uniform treatment guidelines and spotlights areas in dire need of further research, aiming at the comprehensive enhancement of patient outcomes following colorectal cancer surgery.

Evaluation of preoperative blood markers for predicting intra-abdominal infection during colorectal cancer resection: A commentary on recent findings

This commentary evaluates the study by Liu et al. This study investigates the predictive utility of the neutrophil-lymphocyte ratio, platelet-lymphocyte ratio, systemic immune-inflammation index, and carcinoembryonic antigen levels for post-operative intra-abdominal infection following colorectal cancer (CRC) surgery. The study highlights the critical need for analyzing diverse patient demographics and delves into the potential impact of various confounding factors on the predictive accuracy of these markers. Additionally, the commentary advocates for the initiation of prospective studies aimed at validating and enhancing the clinical utility of these biomarkers in the context of CRC treatment. The commentary aims to underscore the importance of broadening the research framework to include a wider patient demographic and more comprehensive factor analyses, thereby enriching the predictive model's applicability and relevance in clinical settings.

Morbidity after accelerated enhanced recovery protocol for colon cancer surgery

Previous studies showed that accelerated enhanced recovery programs (ERPs) with discharge 1-3 days after colorectal surgery are feasible for specific patients without compromising patients' safety. This study aimed to examine the incidence, severity, and treatment of complications after treatment according to an accelerated ERP (CHASE). This accelerated ERP consisted of adjustments in pre-, peri- and postoperative care. Patients treated according to the CHASE protocol were compared to a retrospective cohort of patients who received standard ERAS care. The primary outcome was the rate of severe complications. The overall complication rates were similar in both cohorts (CHASE 30.7% vs ERAS 31.4%, p = 0.958) as well as severe complications (CHASE 20.9% vs ERAS 21.4%, p = 0.950). Among the 113 patients with a complicated course, the readmission rate was significantly higher in the CHASE cohort (41.9% vs 21.4%, p = 0.020). LOS after readmission was longer in the CHASE cohort (p = 0.018), but the total LOS was shorter (4 versus 6 days, p = 0.001). This study demonstrates that accelerated recovery can be safe for ASA I-II patients and has the potential to become a standard of care. Moreover, the CHASE protocol proved to be beneficial in terms of total LOS for patients with complications.

Effect of rapid rehabilitation nursing on improving clinical outcomes in postoperative patients with colorectal cancer

BACKGROUND

Surgical resection is the cornerstone treatment for colorectal cancer. Rapid rehabilitation care predicated on evidence-based medical theory aims to improve postoperative nursing care, subsequently reducing the physical and mental traumatic stress response and helping patients who undergo surgery recover rapidly.

AIM

To assess the effect of rapid rehabilitation care on clinical outcomes, including overall postoperative complications, anastomotic leaks, wound infections, and intestinal obstruction in patients with colorectal cancer.

METHODS

We searched the PubMed, Web of Science, Embase, Elsevier Science Direct, and Springer Link databases from January 1, 2010, to January 1, 2024, to screen eligible studies on rapid rehabilitation care among patients who underwent colorectal cancer surgery. Patients were screened based on the inclusion and exclusion criteria. RevMan 5.4 software was used for statistical analysis of the data.

RESULTS

Twelve studies were enrolled, which included 2420 patients. The results showed that rapid rehabilitation care decreased the incidence of overall postoperative complications (OR: 0.44, 95%CI: 0.26-0.74, P = 0.002), anastomotic leaks (OR: 0.68, 95%CI: 0.41-1.12, P = 0.13), wound infections (OR: 0.45, 95%CI: 0.29-0.72, P = 0.0007), and intestinal obstruction (OR: 0.54, 95%CI: 0.34-0.86, P = 0.01) compared to conventional care. Further trials and studies are needed to confirm these results.

CONCLUSION

Rapid rehabilitation care decreased the occurrence of postoperative complications, anastomotic leaks, wound infections, and intestinal obstruction compared to conventional care in patients who underwent colorectal surgery. Therefore, promoting the application of rapid rehabilitation care in clinical practice cannot be overemphasized.

Predictive Factors for Successful Same-Day Discharge After Minimally Invasive Colectomy and Stoma Reversal

BACKGROUND

Same-day discharge after minimally invasive colorectal surgery is a safe, effective practice in specific patients that can enhance the efficiency of enhanced recovery pathways.

OBJECTIVE

To identify predictive factors associated with success or failure of same-day discharge.

DESIGN

Prospective cohort study from January 2020 to March 2023.

SETTINGS

Tertiary colorectal center.

PATIENTS

Adult patients eligible for same-day discharge with remote postdischarge follow-up included those with minimal comorbidities, residing near the hospital, having sufficient home support, and owning a mobile device.

INTERVENTIONS

Patients were discharged on the day of surgery upon meeting specific criteria, including adequate pain control, tolerance of oral intake, independent mobility, urination, and the absence of complications. Successful same-day discharge was defined as discharge on the day of surgery without unplanned visits in the first 72 hours.

MAIN OUTCOME MEASURES

Factors associated with successful or failed same-day discharge after minimally invasive colorectal surgery.

RESULTS

A total of 175 patients (85.3%) were discharged on the day of surgery, with 14 patients (8%) having an unplanned visit within 72 hours. Overall, 161 patients (78.5%) were categorized as same-day discharge success and 44 patients (21.5%) as same-day discharge failure. The same-day discharge failure group had a higher Charlson Comorbidity Index (3.7 vs 2.8, p = 0.03). Mean length of stay (0.8 vs 3.0, p = 0.00), 30-day complications (10% vs 48%, p = 0.00), and readmissions (8% vs 27%, p = 0.00) were higher in the same-day discharge failure group. Regression analysis showed that failed same-day discharge was associated with higher comorbidities (OR 0.79; 95% CI, 0.66-0.95) and prolonged postanesthesia care unit time (OR 0.99; 95% CI, 0.99-0.99). Individuals who received a regional nerve block (OR 4.1; 95% CI, 1.2-14) and those who did not consume postoperative opioids (OR 4.6; 95% CI, 1-21) were more likely to have successful same-day discharge.

LIMITATIONS

Single-center study.

CONCLUSIONS

Our findings indicate that comorbidities and prolonged postanesthesia care unit stays were associated with same-day discharge failure, whereas regional nerve blocks and minimal postoperative opioids were related to success. These factors may inform future research aiming to enhance colorectal surgery recovery protocols. See Video Abstract .

FACTORES PREDICTIVOS PARA UN ALTA EXITOSA EL MISMO DA DESPUS DE UNA COLECTOMA MNIMAMENTE INVASIVA Y REVERSIN DEL ESTOMA

El alta exitosa el mismo día se definió como el alta el día de la cirugía sin visitas no planificadas en las primeras 72 horas.PRINCIPALES MEDIDAS DE RESULTADO:Factores asociados con el alta exitosa o fallida el mismo día después de una cirugía colorrectal mínimamente invasiva.RESULTADOS:Un total de 175 (85,3%) pacientes fueron dados de alta el día de la cirugía y 14 (8%) pacientes tuvieron una visita no planificada dentro de las 72 horas. En total, 161 (78,5%) pacientes se clasificaron como éxito del alta el mismo día y 44 (21,5%) pacientes como fracaso del alta el mismo día. El grupo de fracaso del alta el mismo día tuvo un índice de comorbilidad de Charlson más alto (3,7, 2,8, p = 0,03). La duración media de la estancia hospitalaria (0,8, 3,0, p = 0,00), las complicaciones a los 30 días (10%, 48%, p = 0,00) y los reingresos (8%, 27%, p = 0,00) fueron mayores en el mismo día grupo de fallo de descarga. El análisis de regresión mostró que el alta fallida el mismo día se asoció con mayores comorbilidades (OR 0,79; IC del 95 %: 0,66; 0,95) y tiempo prolongado en la unidad de cuidados postanestésicos (OR 0,99; IC del 95 %: 0,99; 0,99). Las personas que recibieron un bloqueo nervioso regional (OR 4,1; IC del 95 %: 1,2, 14) y aquellos que no consumieron opioides posoperatorios (OR 4,6, IC del 95 %: 1-21) tuvieron más probabilidades de tener éxito en el mismo día -descarga.LIMITACIONES:Estudio unicéntrico.CONCLUSIONES:Nuestros hallazgos indican que las comorbilidades y las estancias prolongadas en la unidad de cuidados postanestésicos se asociaron con el fracaso del alta el mismo día, mientras que los bloqueos nerviosos regionales y los opioides postoperatorios mínimos se relacionaron con el éxito. Estos factores pueden informar investigaciones futuras destinadas a mejorar los protocolos de recuperación de la cirugía colorrectal. (Traducción-Yesenia Rojas-Khalil ).

Readmission rates following major colorectal surgery

BACKGROUND

Readmissions following colorectal surgery (CRS) have negative clinical, psychological and financial implications. Identifying patients at risk of readmission remains challenging.

AIMS

To determine factors predictive of those likely to require readmission at 40-days following major CRS and to identify novel strategies capable of reducing readmissions.

METHODS

Consecutive patients were studied from a prospectively maintained database. All patients were operated on by a single surgeon in a high-volume centre. Where applicable, photography was recorded by patients and emailed directly to the institutional email of the consultant surgeon. Data was recorded and analysed using descriptive statistics.

RESULTS

515 patients were included over a 15-year period (2007-2022). The mean age at surgery was 64 years (18-93). The majority of patients were male (56.9%, n=293) and underwent cancer surgery (58.2%, n=299). Overall, 55 patients were readmitted within 40 days of major CRS (10.7%). Patients with pre-treatment diagnoses of heart failure (P=0.012), ischemic heart disease (P=0.002), renal impairment (P<0.001), atrial fibrillation (P=0.006), hypercholesterolemia (P=0.001), asthma (P=0.013) and hypertension (P=0.001) were more likely to require readmission. The majority of patients were readmitted for definitive management of surgical site issues (SSIs) (43.7% n=24). Other reasons included bowel obstruction (9.1%, n=5), pelvic sepsis (7.3%, n=4) and gastrointestinal upset (7.3%, n=4).

CONCLUSION

This series demonstrated that patients with cardiopulmonary comorbidities were more likely to be readmitted following major CRS and most readmissions are SSI related. Readmissions for SSIs can be reduced by patients sending photography to the treating surgeon which could reduce readmissions and A&E attendances.

Access, Outcomes, and Costs Associated with Surgery for Malignancy Among People Experiencing Homelessness

BACKGROUND

Little is known about surgery for malignancy among people experiencing homelessness (PEH). Poor healthcare access may lead to delayed diagnosis and need for unplanned surgery. This study aimed to (1) characterize access to care among PEH, (2) evaluate postoperative outcomes, and (3) assess costs associated with surgery for malignancy among PEH.

METHODS

This was a retrospective cohort study of patients in the Healthcare Cost and Utilization Project (HCUP) who underwent surgery in Florida, New York, or Massachusetts for gastrointestinal or lung cancer from 2016 to 2017. PEH were identified using HCUP's "Homeless" variable and ICD-10 code Z59. Multivariable regression models controlling patient and hospital variables evaluated associations between homelessness and postoperative morbidity, length of stay (LOS), 30-day readmission, and hospitalization costs.

RESULTS

Of 67,034 patients at 566 hospitals, 98 (0.2%) were PEH. Most PEH (44.9%) underwent surgery for colorectal cancer. PEH more frequently underwent unplanned surgery than housed patients (65.3% vs 23.7%, odds ratio (OR) 5.17, 95% confidence interval (CI) 3.00-8.92) and less often were treated at cancer centers (66.0% vs 76.2%, p=0.02). Morbidity rates were similar between groups (20.4% vs 14.5%, p=0.10). However, PEH demonstrated higher odds of facility discharge (OR 5.89, 95% CI 3.50-9.78) and readmission (OR 1.81, 95% CI 1.07-3.05) as well as 67.7% longer adjusted LOS (95% CI 42.0-98.2%). Adjusted costs were 32.7% higher (95% CI 14.5-53.9%) among PEH.

CONCLUSIONS

PEH demonstrated increased odds of unplanned surgery, longer LOS, and increased costs. These results underscore a need for improved access to oncologic care for PEH.

The Global Leadership Initiative on Malnutrition criteria for diagnosis of malnutrition and outcomes prediction in emergency abdominal surgery

OBJECTIVES

Malnutrition has adverse postoperative outcomes, especially in emergency surgery. Among the numerous tools for nutritional assessment, this study aims to investigate malnutrition diagnosed by Global Leadership Initiative on Malnutrition criteria and the Global Leadership Initiative on Malnutrition predictive value for outcomes after emergency abdominal surgery.

METHODS

This was a prospective observational study. Among the 468 patients undergoing emergency abdominal surgery admitted to a department of emergency surgery from June 2020 to December 2021, 53 patients were not eligible for enrollment, and 19 patients had missing data. Thus, the final number of participants was 396. Muscle mass was evaluated by skeletal muscle index at the third lumbar vertebra on computed tomography scans, and the lower quartile was defined as the threshold of muscle mass reduction. The associations of Global Leadership Initiative on Malnutrition, Global Leadership Initiative on Malnutrition (muscle mass reduction excluded), and skeletal muscle index with in-hospital mortality, postoperative complications, and postoperative stay were evaluated using χ2. In addition, confounding factors were screened, regression models were established, and the Global Leadership Initiative on Malnutrition predictive value was analyzed for clinical outcome. Ethical approval was obtained from the appropriate department.

RESULTS

Malnutrition was observed in 19.9% of the total 396 patients based on the Global Leadership Initiative on Malnutrition and in 12.4% on the Global Leadership Initiative on Malnutrition (muscle mass reduction excluded). Sarcopenia by skeletal muscle index was found in 24.7% of patients. Univariate analysis indicated that in-hospital mortality, postoperative complications, infective complication rate, and postoperative hospital stay were significantly higher in malnourished and sarcopenic patients. Multivariate analysis found that malnutrition diagnosed by the Global Leadership Initiative on Malnutrition was predictive for complications, infective complications, and postoperative stay (total postoperative complications: odds ratio = 3.620; 95% CI, 1.635-8.015; P = 0.002; infective complications: odds ratio = 3.127; 95% CI, 1.194-8.192; P = 0.020; and postoperative stay: regression coefficient = 2.622; P = 0.022). The Global Leadership Initiative on Malnutrition (muscle mass reduction excluded) identified postoperative complications and postoperative stay (total postoperative complications: odds ratio = 3.364; 95% CI, 1.247-9.075; P = 0.017 and postoperative stay: regression coefficient = 3.547; P = 0.009). Sarcopenia by skeletal muscle index was a risk factor for postoperative complications (odds ratio = 3.366; 95% CI, 1.587-7.140; P = 0.002).

CONCLUSION

The Global Leadership Initiative on Malnutrition and Global Leadership Initiative on Malnutritison (muscle mass reduction excluded) had predictive value for adverse clinical outcomes due to malnutrition in patients undergoing emergency abdominal surgery.

Comorbidities Associated With Increased Likelihood of Postoperative Surgical Site Infection in Patients Treated for Hand or Finger Fracture and/or Dislocations

BACKGROUND

We aimed to determine the relationship between common preoperative comorbidities and subsequent incidence of postoperative surgical site infections (SSIs) in hand and finger fractures and/or dislocations.

METHODS

We queried the American College of Surgeons National Safety and Quality Improvement Program from January 1, 2015 to December 31, 2019. Patients were included in our study if they were treated by open or percutaneous fixation for any hand or finger fracture and/or dislocation. Predictor variables were smoking status, diabetes mellitus status, and obesity (body mass index > 30) status. Primary outcome was incidence of postoperative SSI.

RESULTS

There were a total of 9245 patients included in our study, and 148 patients (1.6%) experienced postoperative SSI. Of these, 59 patients (39.9%) were only smokers, 7 patients (4.7%) only had diabetes mellitus, and 55 patients (37.2%) were only obese. Overall, patients experienced greater odds of sustaining a postoperative SSI if they were a smoker or diabetic compared to non-smokers and non-diabetics, respectively. Considering only open fixation modality, patients with comorbidities were not at significantly increased odds of sustaining postoperative SSI. Considering only percutaneous fixation modality, patients experienced significantly greater odds of sustaining postoperative SSI if they were a smoker compared to non-smoker.

CONCLUSIONS

Common preoperative comorbidities, including smoking status and diabetes mellitus, increase the likelihood of postoperative complication in patients with hand and finger fractures and/or dislocations undergoing surgical treatment. Further investigation into the different relationship of these comorbidities between open and closed fractures with larger sample sizes will be valuable.

Impact of comorbidities on immediate post-operative complications in oral cavity free flap patients

PURPOSE

To examine the relationship between comorbidities and the development of immediate post-operative complications in patients undergoing oral cavity composite resection (OCCR) with free flap (FF) reconstruction.

MATERIALS AND METHODS

Retrospective analysis was completed on all consecutive OCCRs with FF reconstruction performed at a single quaternary care facility between 1999 and 2020. Comorbidities, immediate post-operative complications, patient demographics, and tumor characteristics were collected. Odds ratios (OR) with 95 % confidence intervals were calculated for associations between comorbidities and immediate post-operative complications.

RESULTS

320 patients who underwent OCCR with FF reconstruction were included. One hundred twenty-one (37.8 %) patients developed a post-operative complication during their initial hospital admission. The most common complications were non-pneumonia cardiopulmonary events (14.1 %), pneumonia (9.4 %), and wound infection (8.4 %). Other complications included flap compromise, bleeding, and fistula. On multivariate analysis, patients without comorbid conditions were less likely to develop a post-operative complication (OR 0.64; 0.41-0.98). Atrial fibrillation (OR 2.94; 1.17-7.39) and cerebrovascular disease (OR 2.28; 1.08-4.84) were associated with increased odds of developing any complications. Furthermore, cerebrovascular disease (OR: 2.33; 1.04-5.39) and peripheral vascular disease (OR: 2.7; 1.2-6.08) were independently associated with pneumonia.

CONCLUSION

In this retrospective review of patients undergoing OCCR with FF reconstruction for oral cavity SCC, lack of identifiable comorbidities appeared to be protective for post-operative complications while atrial fibrillation and cerebrovascular disease were associated with increased odds of any complication. Pre-existing vascular disease was also associated with an increased risk of pneumonia.

More than 30 Years of POSSUM: Are Scoring Systems Still Relevant Today for Colorectal Surgery?

BACKGROUND

The Physiological and Operative Severity Score for the enUmeration of Mortality and Morbidity (POSSUM) weights the patient's individual health status and the extent of the surgical procedure to estimate the probability of postoperative complications and death of general surgery patients. The variations Portsmouth-POSSUM (P-POSSUM) and colorectal POSSUM (CR-POSSUM) were developed for estimating mortality in patients with low perioperative risk and for patients with colorectal carcinoma, respectively. The aim of the present study was to evaluate the significance of POSSUM, P-POSSUM, and CR-POSSUM in two independent colorectal cancer cohorts undergoing surgery, with an emphasis on laparoscopic procedures.

METHODS

For each patient, an individual physiological score (PS) and operative severity score (OS) was attributed to calculate the predicted morbidity and mortality, respectively. Logistic regression analysis was used to evaluate the possible correlation between the subscores and the probability of postoperative complications and mortality.

RESULTS

The POSSUM equation significantly overpredicted postoperative morbidity, and all three scoring systems considerably overpredicted in-hospital mortality. However, the POSSUM score identified patients at risk of anastomotic leakage, sepsis, and the need for reoperation. Logistic regression analysis demonstrated a strong correlation between the subscores and the probability of postoperative complications and mortality, respectively.

CONCLUSION

Our results suggest that the three scoring systems are too imprecise for the estimation of perioperative complications and mortality of patients undergoing colorectal surgery in the present day. Since the subscores proved valid, a revision of the scoring systems could increase their reliability in the clinical setting.

Burden of Social and Behavioral Determinants of Health on Infectious Complications in Emergency General Surgery

Background: Infectious complications lead to worse post-operative outcomes and are used to compare hospital performance in pay-for-performance programs. However, the impact of social and behavioral determinants of health on infectious complication rates after emergency general surgery (EGS) remains unclear. Patients and Methods: All patients undergoing EGS in the 2019 Nationwide Readmissions Database were included. The primary outcome of the study was the rate of infectious complications within 30 days, defined as a composite outcome including all infectious complications occurring during the index hospitalization or 30-day re-admission. Secondary outcomes included specific infectious complication rates. Multivariable regression analyses were used to study the impact of patient characteristics, social determinants of health (insurance status, median household income in the patient's residential zip code), and behavioral determinants of health (substance use disorders, neuropsychiatric comorbidities) on post-operative infection rates. Results: Of 367,917 patients included in this study, 20.53% had infectious complications. Medicare (adjusted odds ratio [aOR], 1.3; 95% confidence interval [CI], 1.26-1.34; p < 0.001), Medicaid (aOR, 1.24; 95% CI,1.19-1.29; p < 0.001), lowest zip code income quartile (aOR, 1.17; 95% CI, 1.13-1.22; p < 0.001), opioid use disorder (aOR,1.18; 95% CI,1.10-1.29; p < 0.001), and neurodevelopmental disorders (aOR, 2.16; 95% CI, 1.90-2.45; p < 0.001) were identified as independent predictors of 30-day infectious complications. A similar association between determinants of health and infectious complications was also seen for pneumonia, urinary tract infection (UTI), methicillin-resistant Staphylococcus aureus (MRSA) sepsis, and catheter-association urinary tract infection (CAUTI). Conclusions: Social and behavioral determinants of health are associated with a higher risk of developing post-operative infectious complications in EGS. Accounting for these factors in pay-for-performance programs and public reporting could promote fairer comparisons of hospital performance.

The Relationship Between BMI and Postoperative Complications Among Colorectal Cancer Patients Undergoing Surgery

INTRODUCTION

Colorectal cancer (CRC) is common worldwide, and surgery is one of the main treatments. Postoperative complications are a concern. The primary objective of this study is to determine whether elevated body mass index (BMI), the presence of comorbidities, tumor characteristics, and the type of surgery are associated with an increased risk of postoperative complications such as wound infections, pulmonary complications, anastomotic leak, venous thromboembolism (VTE), bowel obstruction, and incisional hernia. The secondary objective is to describe the characteristics of colorectal cancer patients with different BMI groups.

METHODOLOGY

A retrospective cohort study was conducted using a non-probability sampling technique at a tertiary National Guard Hospital in Riyadh, Saudi Arabia. This study involved 122 patients aged 18 years or more who underwent elective or emergency surgery for colorectal cancer between the years 2015 and 2022. Data analysis was performed using Statistical Package for Social Sciences (SPSS) version 27 (IBM SPSS Statistics, Armonk, NY). Descriptive statistics (mean and standard deviation) were used for quantitative variables, while qualitative variables were presented as percentages and frequencies. Non-parametric tests were applied to compare qualitative variables. Quantitative variables were analyzed using the analysis of variance (ANOVA) test. Significance was established at a p-value of 0.05. Ethical considerations were followed throughout the study. Prior to conducting the study, ethical approval was obtained from the Institutional Review Board of King Abdullah International Medical Research Center (KAIMRC) (approval number: IRB/1598/23).

RESULTS

High BMI scores were observed in patients with postoperative complications. A statistically significant variation in BMI scores (p-value < 0.05) was found between patients with complications and without complications. This observation suggests that factors beyond excessive body weight might contribute to the onset of postoperative complications. Moreover, elevated BMI scores were more prevalent in males and were associated with reduced hemoglobin (Hgb) levels, underscoring the potential influence of physiological variables on the emergence of postoperative complications (p-value < 0.05). Tumors located in the rectum or rectosigmoid regions, as well as partial colectomy procedures, exhibited a higher risk of postoperative complications (p-value < 0.05). However, no significant connections were identified between the presence of comorbidities and the occurrence of postoperative complications (p-value > 0.05).

CONCLUSION

This study highlights the impact of BMI on postoperative outcomes in colorectal cancer patients. Higher BMI was associated with unfavorable postoperative outcomes, such as an increased risk of VTE and fluid collection. However, no significant differences in mortality rates or length of hospital stay (LOS) were observed across various BMI categories. Factors beyond BMI, including tumor characteristics, the type of surgical intervention, and preoperative care, play a significant role in determining postoperative outcomes. Therefore, it is essential to adopt a comprehensive approach that considers multiple factors when managing postoperative complications in colorectal cancer patients, particularly those with higher BMI.

CARE: Protocol of a randomised trial evaluating the feasibility of preoperative intentional weight loss to support postoperative recovery in patients with excess weight and colorectal cancer

AIM

Excess weight increases the risk of morbidity following colorectal cancer surgery. Weight loss may improve morbidity, but it is uncertain whether patients can follow an intensive weight loss intervention while waiting for surgery and there are concerns about muscle mass loss. The aim of this trial is to assess the feasibility of intentional weight loss in this setting and determine progression to a definitive trial.

METHODS

CARE is a prospectively registered, multicentre, feasibility, parallel, randomised controlled trial with embedded evaluation and optimisation of the recruitment process. Participants with excess weight awaiting curative colorectal resection for cancer are randomised 1:1 to care as usual or a low-energy nutritionally-replete total diet replacement programme with weekly remote behavioural support by a dietitian. Progression criteria will be based on the recruitment, engagement, adherence, and retention rates. Data will be collected on the 30-day postoperative morbidity, the typical primary outcome of prehabilitation trials. Secondary outcomes will include, among others, length of hospital stay, health-related quality of life, and body composition. Qualitative interviews will be used to understand patients' experiences of and attitudes towards trial participation and intervention engagement and adherence.

CONCLUSION

CARE will evaluate the feasibility of intensive intentional weight loss as prehabilitation before colorectal cancer surgery. The results will determine the planning of a definitive trial.

Mesenteric traction syndrome - Incidence, impact, and treatment: A systematic scoping review of the literature

BACKGROUND

Mesenteric traction syndrome (MTS) is commonly seen during major abdominal surgery and is characterised by facial flushing, hypotension, and tachycardia 15 min into surgery. MTS also impacts the postoperative course, as severe MTS has been associated with increased postoperative morbidity. However, despite MTS being common and severe MTS causing increased postoperative morbidity, the gaps in the literature are not clearly defined. We aimed to examine the diagnostic criteria, incidence, intraoperative and postoperative impact, and potential preventative measures of MTS while highlighting potential gaps in the literature.

METHODS

We followed the Prisma guidelines and performed a systematic literature search. We included only human studies examining MTS. All hits were screened for title and abstract, followed by a full-text review by at least two authors for determining eligibility for inclusion. Data were extracted and risk of bias was assessed by two independent reviewers.

RESULTS

A total of 37 studies, comprising 1102 patients were included in the review. The combined incidence of MTS during open abdominal surgery was found to be 76%, with 35% developing severe MTS. It was found that the development of MTS was associated with marked haemodynamic changes. It was also found that several different subjective diagnostic criteria exist and that severe MTS was associated with increased postoperative morbidity. Furthermore, several preventative measures for protecting against MTS have been examined, but only on the incidence of MTS and not on the postoperative course.

CONCLUSION

MTS occurs in 76% of patients undergoing major abdominal surgery and is associated with deleterious haemodynamic effects, which are more pronounced in patients developing severe MTS. Severe MTS is also associated with a worse postoperative outcome. However, gaps are still present in the current literature on MTS.

Perineal reconstruction after radical pelvic surgery: A cost-effectiveness analysis

BACKGROUND

Radical resection of pelvic and low rectal malignancies leads to complex reconstructive challenges. Many pelvic reconstruction options have been described including primary closure, omental flaps, and various fasciocutaneous and myocutaneous flaps. Little consensus exists in the literature on which of the various options in the reconstructive armamentarium provides a superior outcome. The authors of this study set out to determine the costs and quality-of-life outcomes of primary closure, vertical rectus abdominus muscle flap, gluteal thigh flap, and gracilis flap to aid surgeons in identifying an optimal reconstructive algorithm.

METHODS

A decision tree analysis was performed to analyze the cost, complications, and quality-of-life associated with reconstruction by primary closure, gluteal thigh flap, vertical rectus abdominus muscle flap, and gracilis flap. Costs were derived from Medicare reimbursement rates (FY2021), while quality-adjusted life-years were obtained from the literature.

RESULTS

Gluteal thigh flap was the most cost-effective treatment strategy with an overall cost of $62,078.28 with 6.54 quality-adjusted life-years and an incremental cost-effectiveness ratio of $5,649.43. Gluteal thigh flap was always favored as the most cost-effective treatment strategy in our 1-way sensitivity analysis. Gracilis flap became more cost-effective than gluteal thigh flap, in the scenario where gluteal thigh flap complication rates increased by roughly 4% higher than gracilis flap complication rates.

CONCLUSION

Our data suggest that, when available, gluteal thigh flap be the first-line option for reconstruction of pelvic defects as it provides the best quality-of-life at the most cost-effective price point. However, future studies directly comparing outcomes of gluteal thigh flap to vertical rectus abdominus muscle and gracilis flap are needed to further delineate superiority.

Variations in Textbook Oncologic Outcomes After Curative-Intent Resection: Early Versus Intermediate Hepatocellular Carcinoma Based on Barcelona Clinic Liver Cancer Criteria and Child-Pugh Classification

BACKGROUND

The impact of early versus intermediate hepatocellular carcinoma (HCC) on short-term "optimal" outcomes remains ill-defined. This study sought to define the incidence of textbook oncologic outcomes (TOO), as well as to identify factors associated with TOO among patients with early versus intermediate HCC.

METHODS

Patients who underwent curative-intent liver resection for HCC (1998-2020) were identified from a multi-institutional database. Textbook oncologic outcome (TOO) was defined as negative surgical margins, no return to the operating room, no extended hospital stay, no severe complications, and no 90-day mortality or readmission. Patients were stratified as early HCC (BCLC 0 or BCLC A/Child-Pugh A) or intermediate HCC (BCLC A/Child-Pugh B or BCLC B). Multivariate logistic regression analysis was used to assess factors associated with TOO.

RESULTS

Among 1383 patients, the overall incidence of TOO was 69.0%. Patients with intermediate HCC were less likely to achieve a TOO (early [71.6 %] vs. intermediate [60.1%]; p < 0.001). On multivariate analysis, factors associated with decreased odds of a TOO were high tumor burden (odds ratio [OR], 0.57; 95% confidence interval [CI], 0.33-1.00), high aspartate transaminase-platelet ratio index (APRI) (OR, 0.46; 95% CI, 0.30-0.70), Charlson Comorbidity Index (CCI) greater than 3 (OR, 0.67; 95% CI, 0.49-0.91), major liver resection (OR, 0.68; 95% CI, 0.52-0.90), and intermediate HCC (OR, 0.68; 95% CI, 0.50-0.93) (all p < 0.05). Notably, although high APRI, CCI greater than 3, and major liver resection contributed to lower odds of a TOO in early HCC, the only factor that adversely impacted TOO in intermediate HCC was high tumor burden.

CONCLUSIONS

Patients with intermediate HCC and early HCC patients with liver dysfunction, comorbidities, or an extensive resection were less likely to achieve an "optimal" postoperative outcome.

The impact of sarcopenia on the postoperative outcome in colorectal cancer surgery

Background and aim

Malnutrition-induced sarcopenia predicts poorer clinical outcomes for patients with cancer. Postoperative complications such as wound infection, anastomotic leak (AL), cardiorespiratory events are the most frequent and devastating postoperative complications in colorectal cancer surgery and are frequently associated with malnutrition.

Methods

We reviewed the recent available literature to assess the relationship between the patient nutritional status and sarcopenia in colorectal surgery. The PubMed database was searched for publications. The included studies were original articles, prospective and randomized trials, clinical, systematic reviews and meta-analyses. The information was structured in a narrative review form.

Results

A simple method to assess malnutrition is to define the presence of sarcopenia (skeletal muscle mass reduction and modified composition) by radiological image analysis. Quantifying the material composition and quality is a novel method in patient-specific therapy. This could be a new perspective in colorectal surgery to reduce postoperative mortality, improve surgical planning, and enhance clinical outcomes. A few recent studies have objectively investigated the presence of sarcopenia in colorectal cancer and its impact on morbidity and mortality, but sometimes the results are contradictory.

Conclusion

There is evolving research to find the most appropriate management method, surgeons must be aware of the existence of sarcopenia to identify this risk factor in the occurrence of postoperative complications in colorectal cancer surgery.

Racial disparities in endoscopic retrograde cholangiopancreatography (ERCP) utilization in the United States: are we getting better?

BACKGROUND

We identified trends of inpatient therapeutic endoscopic retrograde cholangiopancreatography (ERCP) in the United States (US), focusing on outcomes related to specific patient demographics.

METHODS

The National Inpatient Sample was utilized to identify all adult inpatient ERCP in the US between 2007-2018. Trends of utilization and adverse outcomes were highlighted. P-values ≤ 0.05 were considered statistically significant.

RESULTS

We noted a rising trend for total inpatient ERCP in the US from 126,921 in 2007 to 165,555 in 2018 (p = 0.0004), with a significant increase in utilization for Blacks, Hispanics, and Asians. Despite an increasing comorbidity burden [Charlson Comorbidity Index (CCI) score ≥ 2], the overall inpatient mortality declined from 1.56% [2007] to 1.46% [2018] without a statistically significant trend (p = 0.14). Moreover, there was a rising trend of inpatient mortality for Black and Hispanic populations, while a decline was noted for Asians. After a comparative analysis, we noted higher rates of inpatient mortality for Blacks (2.4% vs 1.82%, p = 0.0112) and Hispanics (1.17% vs 0.83%, p = 0.0052) at urban teaching hospitals between July toand September compared to the October to June study period; however, we did not find a statistically significant difference for the Asian cohort (1.9% vs 2.10%, p = 0.56). The mean length of stay (LOS) decreased from 7 days in 2007 to 6 days in 2018 (p < 0.0001), while the mean total hospital charge (THC) increased from $48,883 in 2007 to $85,909 in 2018 (p < 0.0001) for inpatient ERCPs. Compared to the 2015-2018 study period, we noted higher rates of post-ERCP pancreatitis (27.76% vs 17.25%, p < 0.0001) from 2007-2014.

CONCLUSION

Therapeutic ERCP utilization and inpatient mortality were on the rise for a subset of the American minority population, including Black and Hispanics.

Impact of atherosclerosis on the postoperative complications of colorectal surgery in older patients with colorectal cancer

BACKGROUND

Atherosclerosis is associated with various comorbidities; nonetheless, its effect on the postoperative complications of colorectal surgery in older patients with colorectal cancer (CRC) remains unclear. This study aimed to evaluate the impact of atherosclerosis on the postoperative complications of colorectal surgery in older adults with CRC.

METHODS

Patients aged ≥ 65 years who underwent surgery for CRC between April 2017 and October 2020 were enrolled. To evaluate atherosclerosis, we prospectively calculated the cardio-ankle vascular index (CAVI) measured by the blood pressure/pulse wave test and abdominal aortic calcification (AAC) score from computed tomography. Risk factors for Clavien-Dindo grade ≥ III postoperative complications were evaluated by univariate and logistic regression analyses.

RESULTS

Overall, 124 patients were included. The mean CAVI value and AAC score were 9.5 ± 1.8 and 7.0 ± 8.0, respectively. Clavien-Dindo grade ≥ III postoperative complications were observed in 14 patients (11.3%). CAVI (odds ratio, 1.522 [95% confidence interval, 1.073-2.160], p = 0.019), AAC score (1.083 [1.009-1.163], p = 0.026); and operative time (1.007 [1.003-1.012], p = 0.001) were identified as risk factors for postoperative complications. Based on the optimal cut-off values of CAVI and AAC score, the probability of postoperative complications was 27.8% in patients with abnormal values for both parameters, which was 17.4 times higher than the 1.6% probability of postoperative complications in patients with normal values.

CONCLUSIONS

Atherosclerosis, particularly that assessed using CAVI and AAC score, could be a significant predictor of postoperative complications of colorectal surgery in older adults with CRC.

Utility of Preoperative Laboratory Testing for Ambulatory Endoscopic Sinonasal Surgery in Low-Risk Patients

Background

Preoperative laboratory tests (PLTs) are often obtained prior to outpatient surgical procedures. The objective of this study is to examine the current practice of routine PLT in low-risk patients undergoing ambulatory endoscopic sinonasal surgery (ESS) and to assess whether such testing impacts surgical outcomes.

Methods

Patients undergoing ambulatory ESS were identified from the 2011 to 2018 NSQIP database. Low-risk patients were defined as American Society of Anesthesiologist class 1 or 2. PLTs were grouped into hematologic, chemistry, coagulation, and liver function tests. Chi-square analyses and independent samples t-tests were conducted to compare categoric and continuous variables, respectively.

Results

A total of 664 cases met the inclusion criteria, of which 419 (62.1%) underwent at least one PLT. Of these, the most frequent PLT obtained was a complete blood cell count (92.4%). Major complications occurred in 1.5% of patients. There were no statistically significant differences in overall postoperative complications between those with and without PLT ( P = .264). Specifically, no significant difference was seen in the incidence of postoperative bleeding ( P = .184), urinary tract infection ( P = .444), pulmonary embolism ( P = .444), or wound infection ( P = .701). On multivariable analyses, PLT status was not significantly associated with any complication ( P = .097) or unplanned readmission ( P = .898).

Conclusions

Our analysis did not reveal an association between the use of PLT and postoperative morbidity or unplanned readmission in low-risk patients undergoing outpatient ESS.

Perioperative outcomes of emergency and elective colorectal surgery: a bi-institutional study

BACKGROUND

Emergency colorectal surgery tends to be associated with poorer outcomes compared to elective colorectal surgery. This study assessed the morbidity and mortality in patients undergoing emergency and elective colorectal resection in two metropolitan hospitals.

METHODS

Patients were identified retrospectively from two institutions between April 2018 and July 2020. Baseline, operative and postoperative parameters were collected for comparative analysis between emergency and elective surgery groups. A binary logistic regression was performed to identify independent predictors of postoperative complications.

RESULTS

During the study period, 454 patients underwent colorectal resection, 135 were emergency cases (29.74%) and 319 were elective cases (70.26%). Compared with elective resections, patients undergoing emergency resections were observed to have a higher American Society of Anesthesiologists (ASA) score of III to IV (53.33% vs. 38.56%) (P = 0.004). The mortality rate was similar between the emergency and elective group (1.48% vs. 0.63%, P = 0.369). The overall complication rate was higher in patients undergoing emergency resections (64.44% vs. 36.68%, P < 0.001), but the major complication rate was similar between groups (12.59% vs. 10.34%, P = 0.484). Independent predictors for postoperative complications included emergency surgery (Odds Ratio (OR) 2.77, 95% Confidence Interval (CI): 1.66 to 4.61) and an ASA Score of III to IV (OR 2.87, 95% CI: 1.84 to 4.47).

CONCLUSION

The overall complication rate was higher in patients undergoing emergency colorectal resection, however, rates of major complications and mortality were similar between groups. Higher complication rates reflect advanced disease pathology in patients who are more comorbid.

Surgical Care of Patients Experiencing Homelessness: A Scoping Review Using a Phases of Care Conceptual Framework

Homelessness is a growing concern across the world, particularly as individuals experiencing homelessness age and face an increasing burden of chronic health conditions. Although substantial research has focused on the medical and psychiatric care of patients experiencing homelessness, literature about the surgical care of these patients is sparse. Our objective was to review the literature to identify areas of concern unique to patients experiencing homelessness with surgical disease. A scoping review was conducted using a comprehensive database for studies from 1990 to September 1, 2020. Studies that included patients who were unhoused and discussed surgical care were included. The inclusion criteria were designed to identify evidence that directly affected surgical care, systems management, and policy making. Findings were organized within a Phases of Surgical Care framework: preoperative care, intraoperative care, postoperative care, and global use. Our search strategy yielded 553 unique studies, of which 23 met inclusion criteria. Most studies were performed at public and/or safety-net hospitals or via administrative datasets, and surgical specialties that were represented included orthopedic, cardiac, plastic surgery trauma, and vascular surgery. Using the Surgical Phases of Care framework, we identified studies that described the impact of housing status in pre- and postoperative phases as well as global use. There was limited identification of barriers to surgical and anesthetic best practices in the intraoperative phase. More than half of studies (52.2%) lacked a clear definition of homelessness. Thus, there is a marked gap in the surgical literature regarding the impact of housing status on optimal surgical care, with the largest area for improvement in the intraoperative phase of surgical and anesthetic decision making. Consistent use of clear definitions of homelessness is lacking. To promote improved care, a standardized approach to recording housing status is needed, and studies must explore vulnerabilities in surgical care unique to this population.

Relationships between multiple patient safety outcomes and healthcare and hospital-related risk factors in colorectal resection cases: cross-sectional evidence from a nationwide sample of 232 German hospitals

OBJECTIVES

Studies analysing colorectal resections usually focus on a specific outcome (eg, mortality) and/or specific risk factors at the individual (eg, comorbidities) or hospital (eg, volume) level. Comprehensive evidence across different patient safety outcomes, risk factors and patient groups is still scarce. Therefore the aim of this analysis was to investigate consistent relationships between multiple patient safety outcomes, healthcare and hospital risk factors in colorectal resection cases.

DESIGN

Cross-sectional study.

SETTING

German inpatient routine care data of colorectal resections between 2016 and 2018.

PARTICIPANTS

We analysed 54 168 colon resection and 20 395 rectum resection cases treated in German hospitals. The German Inpatient Quality Indicators were used to define colon resections and rectum resections transparently.

PRIMARY OUTCOME MEASURES

Additionally to in-hospital death, postoperative respiratory failure, renal failure and postoperative wound infections we included multiple patient safety outcomes as primary outcomes/dependent variables for our analysis. Healthcare (eg, weekend surgery), hospital (eg, volume) and case (eg, age) characteristics served as independent covariates in a multilevel logistic regression model. The estimated regression coefficients were transferred into ORs.

RESULTS

Weekend surgery, emergency admissions and transfers from other hospitals were significantly associated (ORs ranged from 1.1 to 2.6) with poor patient safety outcome (ie, death, renal failure, postoperative respiratory failure) in colon resections and rectum resections. Hospital characteristics showed heterogeneous effects. In colon resections hospital volume was associated with insignificant or adverse associations (postoperative wound infections: OR 1.168 (95% CI 1.030 to 1.325)) to multiple patient safety outcomes. In rectum resections hospital volume was protectively associated with death, renal failure and postoperative respiratory failure (ORs ranged from 0.7 to 0.8).

CONCLUSIONS

Transfer from other hospital and emergency admission are constantly associated with poor patient safety outcome. Hospital variables like volume, ownership or localisation did not show consistent relationships to patient safety outcomes.

Training prediction models for individual risk assessment of postoperative complications after surgery for colorectal cancer

BACKGROUND

The occurrence of postoperative complications and anastomotic leakage are major drivers of mortality in the immediate phase after colorectal cancer surgery. We trained prediction models for calculating patients' individual risk of complications based only on preoperatively available data in a multidisciplinary team setting. Knowing prior to surgery the probability of developing a complication could aid in improving informed decision-making by surgeon and patient and individualize surgical treatment trajectories.

METHODS

All patients over 18 years of age undergoing any resection for colorectal cancer between January 1, 2014 and December 31, 2019 from the nationwide Danish Colorectal Cancer Group database were included. Data from the database were converted into Observational Medical Outcomes Partnership Common Data Model maintained by the Observation Health Data Science and Informatics initiative. Multiple machine learning models were trained to predict postoperative complications of Clavien-Dindo grade ≥ 3B and anastomotic leakage within 30 days after surgery.

RESULTS

Between 2014 and 2019, 23,907 patients underwent resection for colorectal cancer in Denmark. A Clavien-Dindo complication grade ≥ 3B occurred in 2,958 patients (12.4%). Of 17,190 patients that received an anastomosis, 929 experienced anastomotic leakage (5.4%). Among the compared machine learning models, Lasso Logistic Regression performed best. The predictive model for complications had an area under the receiver operating characteristic curve (AUROC) of 0.704 (95%CI 0.683-0.724) and an AUROC of 0.690 (95%CI 0.655-0.724) for anastomotic leakage.

CONCLUSIONS

The prediction of postoperative complications based only on preoperative variables using a national quality assurance colorectal cancer database shows promise for calculating patient's individual risk. Future work will focus on assessing the value of adding laboratory parameters and drug exposure as candidate predictors. Furthermore, we plan to assess the external validity of our proposed model.

Cancer-related fatigue and treatment burden in surgically treated colorectal cancer patients - A cross-sectional study

OBJECTIVE

This cross-sectional study aimed to describe cancer-related fatigue (CRF) in colorectal cancer (CRC) patients who were surgically treated with curative intent, identify subgroups at risk of elevated fatigue levels and explore associations between CRF and treatment burden.

BACKGROUND

CRF is a prominent symptom among cancer patients. In patients treated for CRC, CRF is associated with adjuvant treatments, low quality of life and reduced ability to self-manage.

METHODS

One hundred thirty-four patients with CRC treated at a Norwegian university hospital between 2016-2018 were included. The Schwartz Cancer Fatigue Scale-6 and the Patient Experience with Treatment and Self-management questionnaires were applied for data collection. Statistical analyses included descriptive statistics and non-parametric approaches to analyse correlations and identify differences between groups. The study adhered to STROBE Statement checklist for reporting of cross-sectional studies.

RESULTS

Median fatigue level was 10.0 (range: 7.0-13.0). Physical fatigue was higher than perceptual fatigue, with medians of 6.0 (interquartile range [IQR]: 3.0-13.0) and 4.0 (IQR: 3.0-12.0), respectively. Higher fatigue levels were associated with age <60 years, advanced cancer and adjuvant treatments. Increased CRF was significantly associated with higher treatment burden on seven of the nine dimensions, adjusted for demographic and clinical variables. The association of fatigue and treatment burden was stronger in survivors <60 years, with advanced cancer, 6-12 months since surgery or who had more comorbid conditions.

CONCLUSIONS

This study showed patients at risk of experiencing CRF following CRC treatment. It established proof of associations between CRF and treatment burden and identified subgroups of CRC patients where this association was stronger.

RELEVANCE TO CLINICAL PRACTICE

Screening of CRF in CRC patients can help clinicians provide individualized treatment and care to manage CRF. Clinicians should consider the association between CRF and treatment burden, especially in subgroups of CRF patients.

Clinical Staging to Estimate the Probability of Severe Postoperative Complications in Patients With Vestibular Schwannoma

Importance

Vestibular schwannomas have long been treated as a homogeneous entity. Clinical symptoms at presentation may help elucidate the underlaying pathophysiologic characteristics of tumor subtypes. Describing the heterogeneity of these benign tumors may assist in predicting clinical outcomes associated with their treatment.

Objective

To create a tumor staging system that incorporates symptoms at presentation and tumor size to predict severe surgical complications.

Design, Setting, and Participants

A retrospective cohort of patients at a single-center tertiary referral center from January 1, 1998, to October 13, 2020, was studied. Patients diagnosed with sporadic vestibular schwannoma surgically treated at Washington University in St Louis, Missouri, were included.

Main Outcomes and Measures

Severe surgical complications within 30 days of surgery as determined by the Clavien-Dindo classification system. Patients experiencing a complication of grade 3 or above were determined to have a severe complication.

Results

Of 185 patients evaluated, 40 (22%) had severe postoperative complications. Twenty of the 40 patients (50%) were women; mean (SD) age was 46 (13) years. Patients with severe complications were more likely to have large tumors (>2.5 cm in largest diameter), vestibular symptoms, and recent hearing loss at presentation. Using conjunctive consolidation, a 4-stage clinical severity staging system that incorporates clinical symptoms and tumor size at presentation was created to predict severe complications. The clinical severity staging system demonstrated an improvement in the ability to discriminate severe complications (C index, 0.754; 95% CI, 0.67-0.84) from a model of tumor size alone (C index, 0.706; 95% CI 0.62-0.79).

Conclusions and Relevance

This cohort study found that, among patients with vestibular schwannoma, symptoms present at initial evaluation, in addition to tumor size, served as predictors of severe postoperative complications. A new clinical severity staging system incorporating symptoms at presentation can be helpful for clinicians to identify patients at high risk for severe postoperative complications.

Use of Machine Learning and Statistical Algorithms to Predict Hospital Length of Stay Following Colorectal Cancer Resection: A South African Pilot Study

The aim of this pilot study was to develop logistic regression (LR) and support vector machine (SVM) models that differentiate low from high risk for prolonged hospital length of stay (LOS) in a South African cohort of 383 colorectal cancer patients who underwent surgical resection with curative intent. Additionally, the impact of 10-fold cross-validation (CV), Monte Carlo CV, and bootstrap internal validation methods on the performance of the two models was evaluated. The median LOS was 9 days, and prolonged LOS was defined as greater than 9 days post-operation. Preoperative factors associated with prolonged LOS were a prior history of hypertension and an Eastern Cooperative Oncology Group score between 2 and 4. Postoperative factors related to prolonged LOS were the need for a stoma as part of the surgical procedure and the development of post-surgical complications. The risk of prolonged LOS was higher in male patients and in any patient with lower preoperative hemoglobin. The highest area under the receiving operating characteristics (AU-ROC) was achieved using LR of 0.823 (CI = 0.798–0.849) and SVM of 0.821 (CI = 0.776–0.825), with each model using the Monte Carlo CV method for internal validation. However, bootstrapping resulted in models with slightly lower variability. We found no significant difference between the models across the three internal validation methods. The LR and SVM algorithms used in this study required incorporating important features for optimal hospital LOS predictions. The factors identified in this study, especially postoperative complications, can be employed as a simple and quick test clinicians may flag a patient at risk of prolonged LOS.

Chronic Obstructive Pulmonary Disease and Its Acute Exacerbation before Colon Adenocarcinoma Treatment Are Associated with Higher Mortality: A Propensity Score-Matched, Nationwide, Population-Based Cohort Study

Simple Summary

This is the first study to reveal that hospitalization frequency for acute exacerbation of chronic obstructive pulmonary disease (AECOPD) before colon adenocarcinoma treatment is a severity-dependent and independent prognostic factor for overall survival in patients with stage I–III colon cancer receiving surgical resection and standard treatments. In patients with colon adenocarcinoma undergoing curative resection, those with chronic obstructive pulmonary disease (COPD) had poorer survival outcomes than had those without COPD. Hospitalization for AECOPD at least once within 1 year before colon adenocarcinoma diagnosis is an independent risk factor for poor overall survival in these patients, and a higher number of hospitalizations for AECOPD within 1 year before diagnosis was associated with poorer survival. Our study may be applied to accentuate the importance of COPD management, particularly the identification of frequent exacerbators and the prevention of AECOPD, before standard colon adenocarcinoma treatments are initiated.

Abstract

Purpose: To investigate whether chronic obstructive pulmonary disease (COPD) and COPD severity (acute exacerbation of COPD (AECOPD)) affect the survival outcomes of patients with colon adenocarcinoma receiving standard treatments. Methods: From the Taiwan Cancer Registry Database, we recruited patients with clinical stage I–III colon adenocarcinoma who had received surgery. The Cox proportional hazards model was used to analyze all-cause mortality. We categorized the patients into COPD and non-COPD (Group 1 and 2) groups through propensity score matching. Results: In total, 1512 patients were eligible for further comparative analysis between non-COPD (1008 patients) and COPD (504 patients) cohorts. In the multivariate Cox regression analysis, the adjusted hazard ratio (aHR; 95% confidence interval (CI)) for all-cause mortality for Group 1 compared with Group 2 was 1.17 (1.03, 1.29). In patients with colon adenocarcinoma undergoing curative resection, the aHRs (95% CIs) for all-cause mortality in patients with hospitalization frequencies of ≥1 and ≥2 times for AECOPD within 1 year before adenocarcinoma diagnosis were 1.08 (1.03, 1.51) and 1.55 (1.15, 2.09), respectively, compared with those without AECOPD. Conclusion: In patients with colon adenocarcinoma undergoing curative resection, COPD was associated with worse survival outcomes. Being hospitalized at least once for AECOPD within 1 year before colon adenocarcinoma diagnosis was an independent risk factor for poor overall survival in these patients, and a higher number of hospitalizations for AECOPD within 1 year before diagnosis was associated with poorer survival. Our study highlights the importance of COPD management, particularly the identification of frequent exacerbators and the prevention of AECOPD before standard colon adenocarcinoma treatments are applied.

Postoperative and long-term survival in relation to life-expectancy after pancreatic surgery in elderly patients (cohort study)

Background

An evaluation of the outcome after pancreatic surgery with focus on post-operative and late survival in elderly patients was performed.

Methods

The study included 1.556 patients from a single HBP unit operated from 1. January 2010 to 31. December 2019. Patients were divided into two cohorts, < 75 years (n = 1.296) and ≥75 years (n = 260). Post-operative outcome was evaluated in all patients and late outcome in patients with adenocarcinoma in the pancreas (n = 765) and the duodenum (n = 117). The follow-up of patients with benign disease and adenocarcinoma was 57.95 (12.1–132.7) and 39.85 (12.0–131.7) months, respectively.

Results

Length of hospital-stay and surgical complications were not significantly different in the two cohorts, but in-hospital death was 1.1% (<75 years) and 3.5% (≥75 years) (p = 0.008). The median overall survival of adenocarcinoma was 29.7 (<75 years) and 24.3 months (≥75 years) (p = 0.3228) with a one, two, and five-years survival of 74.5%, 56.6% and 28.6% vs. 73.6%, 51.1%, and 25.5%. Median time to relapse (46.2% of patients <75 years and 40.5% of patients ≥75 years) was 9 (1 - 51) and 8 (1 - 78) months (p = 0.534), respectively. Adjuvant chemotherapy did not have impact on the survival of the old cohort. Patients who died during the observation period had lost 94% (<75 years) and 87% (≥75 years) of expected remnant life. Estimated years lost in the old cohort was 4.2 in males and 4.9 in females (p = 0.025)

Conclusion

Elderly patients may undergo pancreatic surgery with a low mortality and for adenocarcinoma with an acceptable long-term survival.

•

Surgery is the only potentially curable treatment to pancreatic cancer.

•

Elderly patients may tolerate pancreatic surgery with low mortality.

•

Radical pancreatic surgery improves long-term survival, also in elderly patients.

•

Operability should be evaluated from morbidity and biological age.

•

Pancreatic surgery in elderly should only be performed in high volume centers.

Survival Impact of Chronic Obstructive Pulmonary Disease or Acute Exacerbation on Patients with Rectal Adenocarcinoma Undergoing Curative Resection: A Propensity Score-Matched, Nationwide, Population-Based Cohort Study

PURPOSE

The survival effect of current smoking-related chronic obstructive pulmonary disease (COPD) and COPD with acute exacerbation (COPDAE) is unclear for patients with rectal adenocarcinoma undergoing curative resection.

METHODS

We recruited patients with clinical stage I-IIIC rectal adenocarcinoma from the Taiwan Cancer Registry Database who had received surgery. The Cox proportional hazards model was used to analyze all-cause mortality. We categorized the patients into two groups by using propensity score matching based on COPD status to compare overall survival outcomes: Group 1 (current smokers with COPD) and Group 2 (nonsmokers without COPD).

RESULTS

In the multivariate Cox regression analyses, the adjusted hazard ratio (aHR; 95% confidence interval (CI)) of all-cause mortality for Group 1 compared with Group 2 was 1.25 (1.04-1.51). The aHRs (95% cis) of all-cause mortality for frequency of ≥1 hospitalizations for COPDAE or ≥2 hospitalizations within 1 year before diagnosis were 1.17 (1.05-1.51) and 1.48 (1.03-2.41) compared with no COPDAE in patients with rectal adenocarcinoma undergoing curative resection.

CONCLUSION

In patients with rectal adenocarcinoma undergoing curative resection, being a current smoker with COPD (Group 1) was associated with worse survival outcomes than being a nonsmoker without COPD (Group 2). Being hospitalized at least once for COPDAE within 1 year before the diagnosis of rectal adenocarcinoma is an independent risk factor for poor overall survival in these patients, and a higher number of hospitalizations for COPDAE within 1 year before diagnosis was associated with poorer survival.

Chronic Obstructive Pulmonary Disease Increases the Risk of Mortality among Patients with Colorectal Cancer: A Nationwide Population-Based Retrospective Cohort Study

Background: Colorectal cancer (CRC) is the third leading cause of cancer-related deaths in Taiwan. Chronic obstructive pulmonary disease (COPD) is associated with CRC mortality in several population-based studies. However, this effect of COPD on CRC shows no difference in some studies and remains unclear in Taiwan’s population. Methods: We conducted a retrospective cohort study using Taiwan’s nationwide database. Patients newly diagnosed with CRC were identified from 2007 to 2012 via the Taiwan Cancer Registry dataset and linked to the National Health Insurance research database to obtain their medical records. Propensity score matching (PSM) was applied at a ratio of 1:2 in COPD and non-COPD patients with CRC. The 5-year overall survival (OS) was analyzed using the Cox regression method. Results: This study included 43,249 patients with CRC, reduced to 13,707 patients after PSM. OS was lower in the COPD group than in the non-COPD group. The adjusted hazard ratio (aHR) for COPD was 1.26 (95% confidence interval (CI), 1.19–1.33). Moreover, patients with CRC plus preexisting COPD showed a higher mortality risk in all stage CRC subgroup analysis. Conclusions: In this 5-year retrospective cohort study, patients with CRC and preexisting COPD had a higher mortality risk than those without preexisting COPD, suggesting these patients need more attention during treatment and follow-up.

Can physical prehabilitation prevent complications after colorectal cancer surgery in frail older patients?

INTRODUCTION

Frail patients with colorectal cancer (CRC) are at increased risk of complications after surgery. Prehabilitation seems promising to improve this outcome and therefore we evaluated the effect of physical prehabilitation on postoperative complications in a retrospective cohort of frail CRC patients.

METHODS

The study consisted of all consecutive non-metastatic CRC patients ≥70 years who had elective surgery from 2014 to 2019 in a teaching hospital in the Netherlands, where a physical prehabilitation program was implemented from 2014 on. We performed both an intention-to-treat and per protocol analysis to evaluate postoperative complications in the physical prehabilitation (PhP) and non-prehabilitation (NP) group.

RESULTS

Eventually, 334 elective patients were included. The 124 (37.1%) patients in the PhP-group presented with higher age, higher comorbidity scores and walking-aid use compared to the NP-group. Medical complications occurred in 26.6% of the PhP-group and in 20.5% of the NP-group (p = 0.20) and surgical complications in 19.4% and 14.3% (p = 0.22) respectively. In all frailty subgroups, the medical complications were lower in the PhP-group compared to the NP-group (35.9% vs. 45.5% for patients with ≥2 comorbidities, 36.2% vs. 39.1% for ASA score ≥ III, 29.2% vs. 45.8% for walking-aid use). Differences were not significant.

CONCLUSIONS

In this study, patients selected for physical prehabilitation had a worse frailty profile and therefore a higher a priori risk of postoperative complications. However, the postoperative complication rate was not increased compared to patients who were less frail at baseline and without prehabilitation. Hence, physical prehabilitation may prevent postoperative complications in frail CRC patients ≥70 years.
