RESUMO
INTRODUCTION: Multiple studies have identified risk factors for readmission in colon cancer patients. We need to determine which risk factors, when modified, produce the greatest decrease in readmission for patients so that limited resources can be used most effectively by implementing targeted evidence-based performance improvements. We determined the potential impact of various modifiable risk factors on reducing 30-d readmission in colon cancer patients. METHODS: We used a cohort design with the 2012-2020 American College of Surgeons' National Surgical Quality Improvement Program data to track colon cancer patients for 30 d following surgery. Colon cancer patients who received colectomies and were discharged alive were included. Readmission (to the same or another hospital) for any reason within 30 d of the resection was the outcome measure. Modifiable risk factors were the use of minimally invasive surgery (MIS) versus open colectomy, mechanical bowel preparation, preoperative antibiotic use, functional status, smoking, complications (deep vein thrombosis, pulmonary embolism, myocardial infarction, stroke, infections, anastomotic leakage, prolonged postoperative ileus, extensive blood loss, and sepsis), serum albumin, and hematocrit. RESULTS: 111,691 patients with colon cancer were included in the analysis. About half of the patients were male, most were aged 75 or older, and were discharged home. Overall, 11,138 patients (10.0%) were readmitted within 30 d of surgery. In adjusted analysis, the reduction in readmission would be largest by preventing both prolonged ileus and by switching open colectomies to MIS (28.0% relative reduction) followed by preventing anastomotic leaks (6.2% relative reduction). Improving other modifiable risk factors would have a more limited impact. CONCLUSIONS: The focus of readmission reduction should be on preventing prolonged ileus, increasing the use of MIS, and preventing anastomotic leaks.

Surgical care is now recognized as a fundamental component of universal health coverage. Unfortunately, most of the world is still without access to safe and timely surgical care, including 9 out of 10 people living in low- and middle-income countries (LMICs). Additionally, even in LMICs with sustainable surgical programs, surgical outcomes continue to lag behind those in high-income countries. In this article, we will provide a brief history and introduction to global surgery, an overview of the existing literature on global surgical outcomes, and a discussion surrounding the challenges to building surgical capacity and improving surgical outcomes in LMICs. In addition, we will discuss the existing frameworks for building surgical care into national universal healthcare plans and initiatives striving improve surgical outcomes in LMICs.
RESUMO
BACKGROUND: Multimodal, narcotic-sparing analgesic strategies are an important part of enhanced recovery after surgery protocols. Within such protocols, regional anesthetics have proven to be superior to narcotics. OBJECTIVE: This study aimed to evaluate the impact of the transversus abdominis plane block within an enhanced recovery after surgery protocol on length of stay. DESIGN: A retrospective analysis of patients who underwent colorectal surgery in 2015 to 2016 was completed. The primary end points for this analysis were total length of stay and total narcotics consumed during hospitalization. Length of stay and total narcotic use were compared for patients who received a transversus abdominis plane block versus those that did not. DATA SOURCE: The data were obtained from the data warehouse of a university teaching hospital. SETTINGS: This study took place at a university teaching hospital. PATIENTS: The patients were 18 years or older. MAIN OUTCOME MEASURES: The primary outcomes measured were length of stay and the total narcotics used. RESULTS: A total of 347 patients underwent colorectal procedures under the enhanced recovery protocol. Among these, 186 (54%) received a transversus abdominis plane block. Overall, the mean length of stay was 5.8 days (SD ±5.6), and median length of stay was 4 days. These values compare to a mean length of stay of 9.6 days and median length of stay of 7 days before implementing the enhanced recovery protocol. Patients who received a transversus abdominis plane block had a mean length of stay of 5.1 days compared to 6.6 days for those who did not receive one (p < 0.01). Patients who received a transversus abdominis plane block consumed 736.5 morphine milligram equivalents of opioids compared to 1150.3 morphine milligram equivalents of opioid consumed by those without a transversus abdominis plane block (p < 0.05), a 36% decrease in opioid use. When comparing patients who had a mean length of stay of 4 days with those whose length of stay was >4 days, there was an 80% decrease in opioid use. The readmission rate was 7.8%. LIMITATIONS: The lack of randomization of patients was a limitation of this study. CONCLUSION: The use of transversus abdominis plane block in the setting of a well-structured enhanced recovery protocol was associated with a statistically significant decrease in length of stay by 1.5 days and a 36% decrease in narcotic use.

IMPACTO DE LA ANESTESIA DEL PLANO MUSCULAR DE LOS TRANSVERSOS ABDOMINALES EN LA ESTADA DENTRO UN PROTOCOLO ERAS: ANTECEDENTES:La estrategia analgésica multimodal que consume poco medicamento de tipo narcótico es parte importante en los protocolos de recuperación mejorada postoperatoria. Dentro de dichos protocolos, los anestésicos regionales han demostrado ser superiores a la administración de medicamentos narcóticos.OBJETIVO:Estudiar el impacto del bloqueo del plano muscular de los transversos del abdomen sobre la duración de la estadía dentro de un protocolo de recuperación mejorada postoperatoria.DISEÑO:Se realizó un análisis retrospectivo de los pacientes que se sometieron a cirugía colorrectal entre 2015-2016. Los criterios principales de valoración en el presente análisis fueron la duración total de la estadía y el total de medicamentos narcóticos consumidos durante la hospitalización. Se comparó la duración de la estadía y el uso total de narcóticos en los pacientes que recibieron un bloqueo anestésico del plano muscular de los transversos del abdomen con los que no lo recibieron.FUENTE DE DATOS:Banco de datos de un hospital universitario docente.AMBIENTE:Hospital Universitario Docente.PACIENTES:Adultos desde los 18 años o mayores.PRINCIPALES MEDIDAS DE RESULTADO:Duración de la estadía, cantidad total de medicamentos narcóticos administrados.RESULTADOS:Un total de 347 pacientes se sometieron a procedimientos colorrectales bajo el protocolo ERAS. Entre ellos, 186 (54%) recibieron un bloqueo del plano muscular de los transversos del abdomen. En la globalidad, la duración media de la estadía fué de 5,8 días (DE ± 5,6) y la duración media de la estadía fué de 4 días. Estos resultados fueron comparados con la estadía media de 9,6 días y una estadía media de 7 días antes de implementar el protocolo ERAS. Los pacientes que recibieron un bloqueo del plano muscular de los transversos del abdomen tuvieron una estadía media de 5,1 días en comparación con los 6,6 días de los que no recibieron el mencionado bloqueo (p <0,01). Los pacientes que recibieron el bloqueo del plano muscular consumieron 736,5 miligramos de morfina o su equivalente en opioides, comparados con los 1150,3 de aquellos sin bloqueo del plano muscular (p <0,05) lo que significó una disminución del 36% en la administración de opioides. Al comparar los pacientes que tuvieron una estadía media de 4 días con aquellos cuya estadía fue mayor a 4 días, se evidenció una disminución en el 80% de la administración de opioides. La tasa de reingreso fue del 7,8%.LIMITACIONES:Estudio sin sin aleatorización de pacientes.CONCLUSIÓN:El bloqueo anestésico del plano muscular de los transversos del abdomen dentro un contexto protocolar tipo ERAS o de recuperación mejorada bien estructurada, se asoció con la disminución estadísticamente significativa de la duración de la estadía en 1,5 días y una disminución del 36% en la administración de medicamentos narcóticos.

BACKGROUND: Studies investigating the association between pesticide exposure and colorectal cancer (CRC) risk have been inconclusive. OBJECTIVES: Investigate the association between pesticide exposure and CRC risk through a systematic literature review. METHODS: CRC has the fourth-highest rate of cancer-caused death in the US after lung cancer, breast cancer in women, and prostate cancer in men. Here we have conducted a systematic literature search on studies examining the association between any pesticide exposure and CRC risk using PubMed, MEDLINE via EBSCO host, and Embase according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist. RESULTS: Following the review, 139 articles were included for qualitative evaluation. Study participants were farmers, pesticide applicators, pesticide manufacturers, spouses of pesticide applicators, farm residents, Korean veterans of the Vietnam War, rural communities, and those who consumed food with pesticide residues. The studies' results were split between those with significant positive (39 significant results) and inverse (41 significant results) associations when comparing pesticide exposure and CRC risk. DISCUSSION: From our literature review, we have identified a similar number of significant positive and inverse associations of pesticide exposure with CRC risk and therefore cannot conclude whether pesticide exposure has a positive or inverse association with CRC risk overall. However, certain pesticides such as terbufos, dicamba, trifluralin, S-ethyl dipropylthiocarbamate (EPTC), imazethapyr, chlorpyrifos, carbaryl, pendimethalin, and acetochlor are of great concern not only for their associated elevated risk of CRC, but also for the current legal usage in the United States (US). Aldicarb and dieldrin are of moderate concern for the positive associations with CRC risk, and also for the illegal usage or the detection on imported food products even though they have been banned in the US. Pesticides can linger in the soil, water, and air for weeks to years and, therefore, can lead to exposure to farmers, manufacturing workers, and those living in rural communities near these farms and factories. Approximately 60 million people in the US live in rural areas and all of the CRC mortality hotspots are within the rural communities. The CRC mortality rate is still increasing in the rural regions despite the overall decreasing of incidence and mortality of CRC elsewhere. Therefore, the results from this study on the relationship between pesticide exposure and CRC risk will help us to understand CRC health disparities.

Electronic health records (EHRs) or electronic medical records (EMRs) contain a vast amount of clinical data that can be useful for multiple purposes including research. Disease registries are collections of data in predefined formats for population management, research, and other purposes. There are differences between EHRs and registries in the data structure, data standards, and protocols. Proprietary EHR systems use different coding systems and data standards, which are usually kept secret. For EHR data to flow seamlessly into registries, there is the need for interoperability between EHR systems and between EHRs and registries. The levels of interoperability required include functional, structural, and semantic interoperability. EHR data can be manually mapped to registry data, but that is a tedious, resource-intensive endeavor. The development of data standards that can be used as building blocks for both EHRs and registries will help overcome the problem of interoperability.
RESUMO
Rectal prolapse is a debilitating condition with a complex etiology. Symptoms are most commonly prolapse of the rectum and pain with bowel movements or straining, with worsening fecal incontinence over time due to progressive stretching of the anal sphincters. Physical findings are fairly consistent from patient to patient-most notably diastasis of the levator ani muscles, deep pouch of Douglas, redundant sigmoid colon, a mobile mesorectum, and occasionally a solitary rectal ulcer. Evaluation includes a physical exam or imaging demonstrating the prolapse, and evaluating for other causes of pelvic floor dysfunction. Multiple surgical repairs are available, but treatment must be individualized based on patient symptoms and the presence or absence of constipation or other pelvic floor disorders. Mesh repairs have shown promising results, but carry the added risks of mesh erosion, infection, and mesh migration. The optimal repair has not been clearly demonstrated at this time.
RESUMO
Patients with diffuse large B-cell lymphoma (DLBCL) can present with nodal or extra-nodal disease. The most common extra-nodal site is the gastrointestinal tract, including the stomach or illeo-cecal region. Primary colonic diffuse large B-cell lymphoma (DLBCL) is uncommon and presents a unique diagnostic and therapeutic challenge. We present a case of a middle-aged man who presented with abdominal pain and pathological weight loss and underwent hemi-colectomy for suspected adenocarcinoma. Final pathology revealed DLBCL, completely changing the prognosis and subsequent management. We will discuss some of the aspects of this rare presentation and shed light on therapeutic strategies currently available.

BACKGROUND: Racial disparity exists in colorectal cancer outcomes. The reasons for this are multifactorial. OBJECTIVE: The aim of this study was to evaluate the role of equal treatment of blacks and whites in the elimination of racial disparity in colorectal cancer outcomes. DESIGN: A retrospective cohort study of 878 patients with colorectal cancer diagnosed between 1998 and 2008 was done at a University tertiary referral center. Demographic variables including age, sex, and race were abstracted. Tumor-specific variables including American Joint Committee on Cancer stage, anatomic tumor location, vital status, and survival were obtained. Treatment-specific variables including surgery, chemotherapy, radiotherapy, and follow-up were also obtained. Racial differences in these variables were studied and their effect on overall survival was determined by using univariate and multivariate analyses. The findings were then compared with previous data from our institution. SETTING: University tertiary referral center. MAIN OUTCOME MEASURES: The primary outcomes measured were overall survival and cancer-specific mortality. RESULTS: A total of 878 patients met the inclusion criteria, 186 (21.2%) of whom were black. Blacks were significantly younger at diagnosis in comparison with whites, with a median (quartiles) age of 55 years (28-87) compared with 59 years (23-94) (p = 0.0012). Equal proportions of blacks (78.5%) and whites (79.2%) underwent surgery (p = 0.84), similar proportions of blacks (55.4%) and whites (60.8%) received chemotherapy (p = 0.18), and similar proportions of blacks (17.2%) and whites (20.5%) received radiation therapy (p = 0.31). There was no difference in overall survival or cancer-specific mortality between the 2 racial groups. Univariate analysis showed American Joint Committee on Cancer stage and surgery as the only statistically significant factors for overall survival. On multivariate analysis, stage, surgery, and chemotherapy were the only statistically significant factors. Race was not an independent determinant of survival. CONCLUSIONS: There were no differences in overall survival and cancer-related mortality between blacks and whites, and this may have resulted from identical treatment. The previously noted disparities in treatment and overall survival at our institution have disappeared.

Since the development of the stapled intestinal anastomosis, efforts have been aimed at reducing complications and standardizing methods. The main complications associated with stapled anastomoses include bleeding, device failure, and anastomotic failure (leaks and strictures). These complications are associated with increased cost of care, increase in cancer recurrence, decreased overall survival, poor quality of life, and in some cases the need for further procedures including a diverting ostomy. Reducing these complications therefore has important implications. To this end, techniques to reduce the incidence of anastomotic complications have been the focus of many investigators. In this review, we summarize the current staple line reinforcement technology as well as other adjunctive measures, and specifically discuss the role of biologic materials in this realm.
RESUMO
BACKGROUND: We tested the hypothesis that racial differences that exist in the distribution of ABO blood type would partially explain the racial disparity in overall survival seen in colorectal cancer. METHODS: retrospective analysis of the cancer registry of a university hospital for patients treated for colorectal cancer between 1996 and 2008. Demographic, tumor-specific, and treatment-specific variables were abstracted. We also obtained ABO blood group data. The primary end point was overall survival. We divided patients into two groups based on where they underwent surgery: the University of Arkansas for Medical Sciences (UAMS) or outside facilities. RESULTS: Of 833 patients, 182 (21.8%) were black. There was no difference in overall survival between blacks and whites for the entire group (P = 0.61). There was a statistically significant difference in overall survival between patients at the UAMS and outside facilities (P < 0.0001). For the outside facilities group, there was a statistically significant difference in overall survival between blacks and whites (hazard ratio, CI: 1.48 [1.06-2.00]; P = 0.012); no race difference existed for the UAMS group. The ABO blood group had no effect on overall survival. On stage-stratified univariate and multivariate analyses, chemotherapy and surgery were the only statistically significant determinants of survival. CONCLUSIONS: In this study, racial differences in ABO blood group distribution had no effect on overall survival.

Venous thromboembolism (VTE) can occur after major general surgery. Pulmonary embolism is recognized as the most common identifiable cause of death in hospitalized patients in the United States. The risk of deep venous thrombosis (DVT) and pulmonary embolism (PE) is higher in colorectal surgical procedures compared with general surgical procedures. The incidence of venous thromboembolism in this population is estimated to be 0.2 to 0.3%. Prevention of VTE is considered a patient-safety measure in most mandated quality initiatives. The measures for prevention of VTE include mechanical methods (graduated compression stockings and intermittent pneumatic compression devices) and pharmacologic agents. A combination of mechanical and pharmacologic methods produces the best results. Patients undergoing surgery should be stratified according to their risk of VTE based on patient risk factors, disease-related risk factors, and procedure-related risk factors. The type of prophylaxis should be commensurate with the risk of VTE based on the composite risk profile.
RESUMO
BACKGROUND: Malignant small bowel obstruction has a poor prognosis and is associated with multiple related symptoms. The optimal treatment approach is often unclear. We aimed to compare surgical versus non-surgical management with the aim to determine the optimal approach for managing malignant bowel obstruction. METHODS: S1316 was a pragmatic comparative effectiveness trial done within the National Cancer Trials Network at 30 hospital and cancer research centres in the USA, Mexico, Peru, and Colombia. Participants had an intra-abdominal or retroperitoneal primary cancer confirmed via pathological report and malignant bowel disease; were aged 18 years or older with a Zubrod performance status 0-2 within 1 week before admission; had a surgical indication; and treatment equipoise. Participants were randomly assigned (1:1) to surgical or non-surgical treatment using a dynamic balancing algorithm, balancing on primary tumour type. Patients who declined consent for random assignment were offered a prospective observational patient choice pathway. The primary outcome was the number of days alive and out of the hospital (good days) at 91 days. Analyses were based on intention-to-treat linear, logistic, and Cox regression models combining data from both pathways and adjusting for potential confounders. Treatment complications were assessed in all analysed patients in the study. This completed study is registered with ClinicalTrials.gov, NCT02270450. FINDINGS: From May 11, 2015, to April 27, 2020, 221 patients were enrolled (143 [65%] were female and 78 [35%] were male). There were 199 evaluable participants: 49 in the randomised pathway (24 surgery and 25 non-surgery) and 150 in the patient choice pathway (58 surgery and 92 non-surgery). No difference was seen between surgery and non-surgery for the primary outcome of good days: mean 42·6 days (SD 32·2) in the randomised surgery group, 43·9 days (29·5) in the randomised non-surgery group, 54·8 days (27·0) in the patient choice surgery group, and 52·7 days (30·7) in the patient choice non-surgery group (adjusted mean difference 2·9 additional good days in surgical versus non-surgical treatment [95% CI -5·5 to 11·3]; p=0·50). During their initial hospital stay, six participants died, five due to cancer progression (four patients from the randomised pathway, two in each treatment group, and one from the patient choice pathway, in the surgery group) and one due to malignant bowel obstruction treatment complications (patient choice pathway, non-surgery). The most common grade 3-4 malignant bowel obstruction treatment complication was anaemia (three [6%] patients in the randomised pathway, all in the surgical group, and five [3%] patients in the patient choice pathway, four in the surgical group and one in the non-surgical group). INTERPRETATION: In our study, whether patients received a surgical or non-surgical treatment approach did not influence good days during the first 91 days after registration. These findings should inform treatment decisions for patients hospitalised with malignant bowel obstruction. FUNDING: Agency for Healthcare Research and Quality and the National Cancer Institute.

BACKGROUND: The vast majority of women with breast cancer in sub-Saharan Africa present with advanced stage disease, due primarily to the lack of opportunities for early detection and treatment. As part of a larger effort to increase access to diagnostic and therapeutic services for women's cancers in the Democratic Republic of Congo (DRC), we implemented a curriculum to train the local workforce and a program to build the supportive infrastructure for the diagnosis and treatment of breast cancer at a private sector health facility (Biamba Marie Mutombo Hospital) in Kinshasa. STUDY DESIGN: After onsite trainings in the DRC by a US breast surgeon (RT), Congolese surgeons, general physicians, physician assistants, and nurses used the Phillips Lumify smart-phone ultrasound device to perform and interpret the results of whole breast ultrasound on symptomatic women. Surgeons were trained to perform ultrasound-guided core needle biopsy on those who met the criteria for tissue diagnosis, after which they trained nurses to do the same. RESULTS: Over 3 years, 5,211 patients were identified as having a breast abnormality on clinical breast examination. Ultrasound abnormalities were noted in 1,493 (27%) patients, of which 632 (42%) met the criteria for ultrasound-guided core needle biopsy or fine needle aspiration. Pathology reports were available on 368 (58%) patients who underwent biopsy, of which 164 were malignant and 204 benign. CONCLUSIONS: We demonstrated how the "ability to look" using smart technology can be successfully used to augment clinical breast exam and triage patients for biopsy in a resource-constrained African setting.

BACKGROUND: Sacral tumors present a significant challenge to the spine surgeon. As new techniques have evolved in recent years, these lesions have become more amenable to aggressive surgical treatment. Although sacral tumors make up only a small minority of spinal tumors, their surgical management warrants special consideration. METHODS: Based on our experience, we highlight 3 important surgical nuances specifically for the treatment of sacral tumors: preservation and maximization of neurologic function, protection of ventral abdominal and pelvic structures, and lumbopelvic fixation. RESULTS: Two cases of patients with sacral tumors treated at our institution are presented to illustrate these points. Both patients had successful postoperative courses, and remained pain free, well-fixated, and neurologically intact at 3-4 month follow-up. They had no evidence of biomechanical instability. CONCLUSIONS: To ensure a successful outcome, a goal-directed, methodical approach is required.

To test the efficacy of a community-based intervention, Empowering Communities for Life (EC4L), designed to increase colorectal cancer (CRC) screening through fecal occult blood test (FOBT) in rural underserved communities in a randomized controlled trial. Participants were randomized into 3 groups (2 interventions and 1 control). Interventions were delivered by community lay health workers or by academic health professionals. The main outcome of interest was return rate of FOBT screening kit within 60 days. Participants included 330 screening-eligible adults. The overall return rate of FOBT kits within 60 days was 32%. The professional group (Arm 2) had the highest proportion of returned FOBTs within 60 days at 42% (n = 46/110), a significantly higher return rate than the lay group (Arm 1) [28%(n = 29/103);P = 0.0422] or control group (Arm 3) [25%(n = 29/117);P = 0.0099]. Thus, one arm (Arm 2) of our intervention produced significantly higher CRC screening through FOBT. Community-based participation partnered with academic health professionals enhanced CRC screening among rural and poor-resourced communities.

Precision public health requires research that supports innovative systems and health delivery approaches, programs, and policies that are part of this vision. This study estimated the effects of health insurance mandate (HiM) variations and the effects of physician utilization on moderating colorectal cancer (CRC) screening rates. A time-series analysis using a difference-in-difference-in-differences (DDD) approach was conducted on CRC screenings (1997-2014) using a multivariate logistic framework. Key variables of interest were HiM, CRC screening status, and physician utilization. The adjusted average marginal effects from the DDD model indicate that physician utilization increased the probability of being "up-to-date" vs. non-compliance by 9.9% points (pâ¯=â¯0.007), suggesting that an estimated 8.85 million additional age-eligible persons would receive a CRC screening with HiM and routine physician visits. Routine physician visits and mandates that lower out-of-pocket expenses constitute an effective approach to increasing CRC screenings for persons ready to take advantage of such policies.

Fiber bundle microendoscopic imaging of colorectal tissue has shown promising results, for both qualitative and quantitative analysis. A quantitative image quality control and image feature extraction algorithm was previously designed for quantitative image feature analysis of proflavine-stained ex vivo colorectal tissue. We investigated fluorescein as an alternative topical stain. Images of ex vivo porcine, caprine, and human colorectal tissue were used to compare microendoscopic images of tissue topically stained with fluorescein and proflavine solutions. Fluorescein was shown to be comparable for automated crypt detection, with an average crypt detection sensitivity exceeding 90% using a combination of three contrast limit pairs.
