RESUMO
BACKGROUND: Against the technological advances in limb salvage, below-the-knee amputation (BKA) remains a common procedure. Although most elective BKA is classified as clean operation, the reported stump complication rate is much higher than predicted. Postoperative casting (PC) may reduce the number of these complications. The aim of this study was to compare the efficacy of elastic bandage with knee immobilizer (EBKI) and PC in BKA stump complications. METHODS: Retrospective cohort comparison design identified patients who underwent BKA between 2000 and 2023 for non-correctable critical limb ischemia (CLI), or excessive tissue loss secondary to CLI, infection, severe neuropathy, or the combination of these and stratified them into 2 cohorts based on their postoperative stump dressing: EBKI and PC. BKAs that were done for trauma or neoplastic processes were excluded. The primary outcome measures: wound healing in 6 weeks and length of stay (LOS). SECONDARY OUTCOME MEASURES: stump injury, infection, dehiscence, necrosis, number of higher-level amputations, knee contracture, and post-BKA mobility with Special Interest Group of Amputee Medicine score. RESULTS: One hundred sixteen patients with 122 limbs (52 EBKI and 70 PC) were found who met inclusion criteria and analyzed. The groups were comparable in demographics and comorbidities and preoperative variables, including mobility. The primary wound healing at 6 weeks was higher (P = 0.007); wound dehiscence (P = 0.01) and LOS (P = 0.006) was lower in the PC group compared to EBKI group. The PC group achieved higher Special Interest Group of Amputee Medicine mobility score and lower number of contractures developed compared to the EBKI group. CONCLUSIONS: Applying and maintaining PC to the BKA stump during the first month of healing reduced the incidence of stump complications, shortened the LOS, and improved postrehabilitation mobility results. We found no effect of PC on postoperative infections, stump necrosis, and higher-level amputations.
RESUMO
This report describes two cases of rarely reported, severe large arterial vascular spasms seen on computed tomography images after methamphetamine abuse. Although the effects of methamphetamine on the central nervous system and smaller arteries are relatively well known, its effects on large caliber arteries are rarely discussed. We present two cases of severe large arterial multisegmented vasospasm, captured on contrast-enhanced computed tomography, several hours after methamphetamine abuse. One of the patients was discharged without apparent tissue loss or organ failure. The other developed severe heart failure, liver failure, and toe gangrene. The publication of the de-identified images has been approved by the VA Central California Health Care System's Research and Development Committee and Privacy Officer. Vascular surgeons and, perhaps, acute care physicians, who are usually aware of small arterial vasospastic conditions, should also be aware of this methamphetamine-induced large arterial finding, which can be quite dramatic in appearance on imaging.
RESUMO
Frailty is defined as a state of decreased physiologic reserve contributing to functional decline and adverse outcomes. Racial disparities in frail patients have been described sparsely in the literature. We aimed to assess whether race influences frailty status in geriatric patients undergoing revascularization for peripheral artery disease (PAD) with chronic limb-threatening ischemia (CLTI). A 5-year analysis of the National Surgical Quality Improvement Program database included all geriatric (65 years and older) patients who underwent revascularization for lower extremity PAD with CLTI. The frailty index was calculated using a 11-variable modified frailty index and a cutoff of 0.27 indicated frail status. The primary outcome was an association of race or ethnicity with frailty status. We included 7,837 geriatric patients who underwent a surgical procedure (open: 55.2%) for PAD with CLTI. Mean age of patients was 75.4 years, 63.8% were male, 24.1% (nâ¯=â¯1,889) were frail, and 21.8% (nâ¯=â¯1,710) were African American (AA). Overall complication rate was 11.2% (nâ¯=â¯909) and overall mortality rate was 1.9% (nâ¯=â¯148). AA patients were more likely to be frail than White patients (29.6% v 23.9%; Pâ¯=â¯.03). AA and Hispanic patients were more likely to have complications (Pâ¯=â¯.03 and Pâ¯=â¯.001) and require readmission (Pâ¯=â¯.015 and Pâ¯=â¯.001) compared with White and non-Hispanic patients, respectively. Frail AA and frail Hispanic patients were more likely to have 30-day complications and readmission compared with frail White and frail non-Hispanic patients, respectively. Race and ethnicity influence frailty status in geriatric patients with PAD and CLTI. These disparities exist regardless of age, sex, comorbid conditions, and type of operative procedure. Additional studies are needed to highlight disparities by race and ethnicity to identify potentially modifiable risk factors to improve outcomes.

BACKGROUND: Establishing a forearm arteriovenous fistula (AVF) offers preferred cannulation sites and preserves proximal access opportunities. When a radiocephalic AVF at the wrist is not feasible and the upper arm cephalic and median cubital veins are inadequate, an AV graft or more complex access procedure is often required. Creating a retrograde flow forearm AVF (RF-AVF) is a valuable alternative where the mid-forearm median antebrachial or cephalic vein is adequate, offering forearm cannulation zones with AVF outflow through deep and superficial collaterals. We report our technique and results. METHODS: We retrospectively reviewed our vascular access data base of consecutive patients during an 11-year study period where a RF-AVF established the only available cannulation target in the forearm. In addition to physical examination, all patients had ultrasound vessel mapping. RESULTS: A forearm access was established with a RF-AVF as the only opportunity for cannulation in 48 patients. Ages were 14-86 years (median = 62 years). Forty-four percent female, 63% diabetic, 13% obese, and 29% had previous access operations. Inflow was proximal radial artery in 47 individuals and one proximal ulnar. Nine AVFs (19%) failed at 2-66 months (median 14 months). One RF-AVF was ligated due to arm edema. Follow-up was 2-111 months (median = 23.5 months). Primary and cumulative patency rates were 62% and 91% at 12 months, and 46% and 85% at 24 months. Five patients were lost to follow-up with functioning RF-AVFs (mean 41 months). Twenty-three patients (48%) died during F/U of causes unrelated to access procedures (mean 25 months). CONCLUSIONS: Establishing a reverse flow forearm AVF offers a successful autogenous access option in the forearm for selected patients with an inadequate distal radial artery and/or cephalic vein at the wrist, avoiding more complex or staged procedures and preserving upper arm sites for future use. A proximal radial artery inflow procedure is recommended.

BACKGROUND: Loss of independence (LOI) is a significant concern in patients undergoing liver surgery. Although the risks of morbidity and mortality have been well studied, there is a dearth of data regarding the risk of LOI. Therefore, this study aimed to assess predictors of LOI after liver surgery. METHODS: This study utilized the National Surgical Quality Improvement Program (NSQIP) data from 2015 to 2018 from a retrospective cohort study of patients undergoing liver resections. LOI was defined as the change from preoperative functional independence to the postoperative discharge requirement in a post-care facility. Frailty was defined using the modified frailty index-5 (mFI-5). RESULTS: A total of 22,463 patients underwent hepatectomy via the NSQIP during the study period. In total, 22,067 participants were included in the analysis. A total of 4.7% of patients had LOI after surgery and were discharged to a rehabilitation center or nursing facility. mFI-1 was an independent predictor of LOI (OR:2.2 [1.9-4.3]). However, the odds for LOI were higher (OR:5.1[2.5-8.2]) in patients with mFI ≥ 2. CONCLUSION: LOI is an important outcome of liver surgery. Frailty is a predictor of LOI and should be used as a guide to inform patients about the potential outcomes.

BACKGROUND: Venous thromboembolism (VTE) is commonly associated with hypercoagulability in patients with cancer; however, there have been few investigations of VTE as the first sign of malignancy and even fewer performed in the United States. The aim of our study was to evaluate the incidence and predictors of unrecognized malignancy in patients presenting with VTE. METHODS: We performed a 1-year retrospective analysis of the Nationwide Readmission Database, including patients aged 18 years or older, presenting with a primary diagnosis of deep vein thrombosis (DVT) or a pulmonary embolism (PE). Patients known to have preexisting malignant diseases were excluded. Outcomes included the rate of newly diagnosed malignancy within 6 months from the discovery of VTE and demographic or associated illness predictors for the diagnosis of malignancy. A regression analysis was performed, based on which a VTE malignancy score was developed. RESULTS: A total of 116,048 patients were identified with VTE (49.8% DVT, 41.7% PE, 8.6% DVT and PE), 16% (n = 18,294) with malignancy. Of the remaining 97,754 patients, 31% were readmitted within 6 months. The incidence of newly diagnosed malignancy within 6 months was 2.4% (n = 2354). The most common malignancies were gastrointestinal in origin (29.2%). Demographic and diagnostic predictors for malignancy included age 65 years or older, female sex, inferior vena cava (IVC) thrombus, upper extremity thrombus, and a Charlson Comorbidity Index score of 5 or more. Receiver operating characteristic curve analysis found a cutoff VTE Malignancy score of 3 (sensitivity, 86%; specificity, 89%) to be predictive of an increased risk of a newly discovered malignancy within 6 months. CONCLUSIONS: VTE can be a risk indicator of underlying malignancy. Validation of a patient risk stratification score using multiple demographic or comorbid predictors for VTE on index admission may offer an opportunity for earlier diagnosis of occult malignancy.

BACKGROUND: American Indians (AI) or Alaska Natives, or in combination with another race, comprised 6.8 million individuals in 2010 and the population is expected to exceed 10 million in the current census. Diabetes is more common in AIs than in other races in the United States and is responsible for 69% of new onset end stage renal disease in AI patients. The incidence of obesity is also higher among AIs. As both diabetes and obesity make creating a successful autogenous vascular access more challenging, we reviewed our experience creating arteriovenous fistulas in AI patients. METHODS: Our vascular access database was reviewed for consecutive new AI patients undergoing creation of a hemodialysis vascular access during a 10-year period. Each patient underwent ultrasound vessel mapping by the operating surgeon in addition to history and physical examination. The goal for initial cannulation was 4-6 weeks after access creation. Minimal AVF flow volume for cannulation was 500 mL/min with an outflow vein diameter of 6 mm. RESULTS: 235 consecutive new AI patients were identified. All patients had an autogenous access constructed. The median age was 56 years (range, 15-89 years). Diabetes was present in 85% and 42% were female. Obesity was noted in 27% of the patients and 37% had previous vascular access operations. Primary patency at 12 and 24 months was 62% and 46%, respectively. Cumulative patency at 12 and 24 months was 96% and 94%, respectively. Female gender and previous access operations were associated with lower primary (P = 0.002 and 0.02, respectively) and cumulative patency (P = 0.01 and 0.04, respectively). Obesity was associated with lower cumulative access patency (P = 0.02). Overall, 74% of the access operations used the radial or ulnar artery for AVF inflow. Distal radial artery inflow AVFs were associated with longer patient survival (P = 0.01) and individuals with proximal radial inflow had longer survival when compared to brachial artery AVFs. Previous access operations were associated with shorter patient survival (P = 0.04). CONCLUSIONS: Safe and functional arteriovenous fistulas can be created for American Indians despite a higher prevalence of vascular access risk factors such as diabetes and obesity.

BACKGROUND: Frailty syndrome is an established predictor of adverse outcomes after surgical procedures. Our study aimed to compare the simplified National Surgical Quality Improvement Program 5-factor-modified frailty index (mFI-5) to its prior 11-factor-modified frailty index (mFI-11) with respect to the predictive ability for mortality, postoperative complications, and unplanned 30-d readmission in patients undergoing lower limb amputation. METHODS: The National Surgical Quality Improvement Program (2005-2012) databank was queried for all geriatric patients (>65 y) who underwent above-knee and below-knee amputations. We calculated each mFI by dividing the number of factors present for a patient by the total number of available factors. To assess the correlation between the mFI-5 and mFI-11, we used Spearman's rho rank coefficient. We then compared the two indices for each outcome (30-d complication, 30-d mortality, and 30-d readmission) and C-Statistic using predictive models. RESULTS: A total of 8681 patients were included with mean age of 76 ± 9 y, complication rate 35.8%, mortality rate 10.2%, and readmission rate 15.9%. There was no difference in type of amputation in frail and nonfrail. Correlation between the mFI-5 and mFI-11 was above 0.9 for all outcome measures. Both mFI-5 and mFI-11 indexes had strong predictive ability for mortality, postoperative complications, and 30-d readmissions. CONCLUSIONS: In patients undergoing major lower limb amputation, we found mFI-5 and the mFI-11 were equally effective in predicting postoperative outcomes. Frailty remained a strong predictor of postoperative complications, mortality, and 30-d readmission.

OBJECTIVE: To assess the safety and efficacy of retrograde arterial recanalization of infrainguinal CTOs in the OBL setting. METHODS: Consecutive patients who underwent interventions for lower extremity CTOs in the OBL setting by a single vascular surgeon were evaluated (January 2013-November 2017). If antegrade crossing was not possible, then a retrograde distal approach was used. Patient characteristics, CTO location, procedural time, contrast, anticoagulation and radiation doses and costs were recorded. Post-procedural complications were documented on post-procedure day 1 and 10-14 days post procedure. Three groups were compared: group 1-antegrade approach for femoropopliteal CTOs; group 2-antegrade approach for tibial CTOs, and; group 3-retrograde approach for femoropopliteal and tibial CTOs. RESULTS: Two hundred and thirty-seven patients were studied. In 39 (16.5%), the lesions could not be crossed. A successful antegrade approach was used in 185 of them, of which 69% (group 1, n = 128) patients had femoropopliteal CTOs and 31% (group 2, n = 57) had tibial CTOs. Fourteen patients (5.9%, group 3) were treated by retrograde distal approach. Group 3 patients received higher contrast doses than groups 1 and 2 (p = 0.01). However, patients in groups 1 and 2 received similar contrast doses. Group 3 patients had the highest operative time and treatment costs followed by group 1 and then group 2 (p = 0.01). Three femoral pseudoaneurysms were noted in group 1, and 2 in group 2. No complications were seen in group 3. CONCLUSIONS: Although the operative times, costs, radiation and contrast dose are higher with retrograde arterial access, it represents a safe and effective method for the crossing of CTO infrainguinal lesions in an ambulatory venue.

Timely creation and maintenance of a safe and reliable vascular access is essential for hemodialysis patients with end-stage renal disease. Hemodialysis access-induced distal ischemia (HAIDI) is a recognized complication of arteriovenous fistulas and grafts that may result in serious or even devastating consequences. Avoiding such complications is clearly preferred over treatment of HAIDI once established. Proper recognition of patients at increased risk of HAIDI includes careful pre-operative evaluation of the patient's medical and surgical history along with physical examination and imaging to determine a plan for creating a functional permanent access while minimizing the risk of distal ischemia. Our aim is to review identifying characteristics of individuals at risk of HAIDI and provide recommendations regarding pre-operative assessment. Vascular access options and techniques are suggested for establishing a functional vascular access without distal ischemia for such patients.

BACKGROUND: Frailty is a state of decreased physiologic reserve contributing to functional decline and is associated with adverse surgical outcomes, particularly in the elderly. Racial disparities have been reported previously both in frail individuals and in limb-salvage patients. Our goal was to assess whether race and ethnicity are disproportionately linked to frailty status in geriatric patients undergoing lower-limb amputation, leading to an increased risk of complications. METHODS: A 3-year analysis was conducted of the National Surgical Quality Improvement Program database and included all geriatric (age ≥65 years) patients who underwent amputation of the lower limb. The frailty index was calculated using the 11-factor modified frailty index with a cutoff limit of 0.27 defined for frail status. Outcomes were 30-day complications, mortality, and readmissions. Multivariate regression analysis was performed. RESULTS: A total of 4,218 geriatric patients underwent surgical amputation of a lower extremity (above knee: 41%; below knee: 59%). Of these patients, 29% were frail, 26% were African American, and 9% were Hispanic. Being African American (odds ratio: 1.6 [1.3-1.9]) and Hispanic (odds ratio: 1.1 [1.05-2.5]) was independently associated with frail status. Frail African Americans had a higher likelihood of 30-day complications (odds ratio: 3.2 [1.9-4.4]) and 30-day readmissions (odds ratio: 2.9 [1.8-3.6]) when compared with nonfrail individuals. Similarly, frail Hispanics had higher 30-day complications (odds ratio: 2.6 [1.9-3.1]) and 30-day readmissions (odds ratio: 1.4 [1.1-2.7]) compared with nonfrail Hispanics/Latinos. CONCLUSION: African American and Hispanic geriatric patients undergoing lower-limb amputation are at increased risk for frailty status and, as a result, increased associated operative complications. These disparities exist regardless of age, sex, comorbid conditions, and location of amputation. Further studies are needed to highlight disparities by race and ethnicity to identify potentially modifiable risk factors, decrease frailty, and improve outcomes.

BACKGROUND: Frailty syndrome is an established predictor of adverse outcomes after carotid surgery. Recently, a modified 5-factor National Surgical Quality Improvement Program frailty index has been used; however, its utility in vascular procedures is unclear. The aim of our study was to compare the 5-factor modified frailty index (mFI-5) with the 11-factor modified frailty index (mFI-11) regarding value and predictive ability for mortality, postoperative infection, and unplanned 30-day readmission. METHODS: The mFI was calculated by dividing the number of factors present for a patient by the number of available factors for which there were no missing data. Spearman rho test was used to assess the correlation between the mFI-5 and mFI-11. Predictive models, using both unadjusted and adjusted logistic regressions, were created for each outcome for carotid endarterectomy using 2005-2012 National Surgical Quality Improvement Program data, the last year all mFI-11 variables existed. RESULTS: A total of 36,000 patients were included with mean age of 74.6 ± 5.9 years, complication rate of 10.7%, mortality rate of 3.1%, and readmission rate of 6.2%. Correlation between mFI-5 and mFI-11 was above 0.9 across all outcomes for patients. mFI-5 had strong predictive ability for mortality, postoperative complications, and 30-day readmission. CONCLUSIONS: The mFI-5 and mFI-11 are equally effective predictors of postoperative outcomes in patients undergoing carotid endarterectomy. mFI-5 is a strong predictor of postoperative complications, mortality, and 30-day readmission.

BACKGROUND: Frailty syndrome confers a greater risk of morbidity and mortality after operative interventions. The aim of the present study was to assess the effect of frailty on the outcomes after carotid interventions, including both carotid endarterectomy (CEA) and carotid artery stenting (CAS). METHODS: We performed an 8-year (2005-2012) retrospective analysis of the National Surgery Quality and Improvement Program database, including patients who had undergone CEA or CAS for carotid artery stenosis. A modified frailty index score was calculated. Frail status was defined as a modified frailty index score of ≥0.27. The outcome measures were inpatient complications, mortality, failure to rescue (FTR), hospital length of stay, and 30-day readmissions. Multivariable regression analysis was performed to study the association between frailty and the perioperative outcomes. RESULTS: The data from 37,875 patients were included. Of the 37,875 patients, 95.7% had undergone CEA, and 27.3% of the patients were frail (27% of the CEA and 26% of the CAS groups had qualified as frail). Overall, 11.7% of the patients had experienced complications, 2.2% had died, and 6.7% had been readmitted after discharge. On regression analysis, after controlling for age, gender, albumin level, type of surgery, and American Society of Anesthesiologists class, frail status was an independent predictor of complications (23.5% vs 7.2%; P < .001), mortality (5.2% vs 1.1%; P = .02), FTR (12.1% vs 4.7%; P = .02), and 30-day readmissions (14.9% vs 3.7%; P = .03). On subanalysis of the patients who had undergone CAS, no association was found between frail status and the occurrence of complications (odds ratio [OR], 1.5; 95% confidence interval [CI], 0.8-3.2), mortality (OR, 1.2; 95% CI, 0.6-2.7), FTR (OR, 0.9; 95% CI, 0.4-2.3), and 30-day readmission rate (OR, 1.1; 95% CI, 0.5-3.1). CONCLUSIONS: Frailty syndrome was associated with morbidity and mortality among patients undergoing surgical interventions for carotid stenosis. In the present study, frailty was associated with significant mortality and morbidity for those who had undergone CEA but not for those who had undergone CAS. However, the present study was not designed to determine the optimal treatment of frail patients. Incorporating frailty status into the treatment algorithm (CEA vs CAS) might provide a more accurate risk assessment and improve patient outcomes.

BACKGROUND: Surgical site infection (SSI) is an established quality indicator and predictor for adverse patient outcomes. Multiple strategies have been established to reduce SSI; however, optimum protocol remains unclear. The aim of the study was to assess the impact of established protocol on SSI after colon surgery. METHODS: We established a colon SSI bundle in 2017, which includes a chlorhexidine prescrub followed by chloraPrep, betadine wound wash, antibiotic infused irrigation, use of closure tray, and incision coverage with silver impregnated dressing. Retrospective analysis of a 2-y (2016-2017) prospectively collected before and after analysis of all patients undergoing elective colon surgery was performed. Patients were divided into two groups: preprotocol (PP: year 2016) and postprotocol (PoP: year 2017). Patients in the two groups were matched using propensity score matching for age, gender, comorbidities, Anesthesiology Severity Score, indication of procedure, and procedure type. Outcome measures were SSI, hospital length of stay, and readmission rate. RESULTS: A total of 328 patients were analyzed, and after propensity matching, 94 patients (PP:47 and PoP:47) were included. The mean age was 63.7 ± 16.4 y, 43.6% male, and 44.6% of procedures were performed laparoscopically. There was no difference in demographics, comorbidities, and procedure details between two groups. PoP patients had significantly lower superficial (odds ratio: 0.91 [0.74-0.98]; P = 0.045) and deep SSI (odds ratio:0.97 [0.65-0.99]; P = 0.048) than PP patients. PoP patient had shorter length of stay (P = 0.049) and trend toward lower readmission rate (P = 0.098) compared with PP patients and an 85% reduction in the Centers for Medicare and Medicaid Services standardized infection rate. CONCLUSIONS: Protocol-driven patient care improves patient outcomes. SSI bundle reduced SSI in patient undergoing colon surgery. Establishing national SSI bundles will help standardize care and help optimize patient outcomes.

BACKGROUND: The influence of hospital-related factors on outcomes following colorectal surgery is not well-established. The aim of our study was to evaluate the relationship between hospital factors on outcomes in surgically managed colorectal cancer patients. METHODS: We performed a 2-year (2014-2015) analysis of the NIS database. Adult (> 18 years) patients who underwent open or laparoscopic colorectal resection were identified using ICD-9 codes. Patients were stratified based on hospital: volume (low vs. high), teaching status, and location (urban vs. rural). Outcome measures were complications and mortality. Multivariate logistic regression was performed. RESULTS: A total of 153,453 patients with CRC were identified of which 35.3% underwent surgical management. Mean age was 69 ± 13 years, 51.6% were female, and 67% were white. Twenty-seven percent of the patients were managed at a high-volume center, 48% at intermediate-volume center while 25% at a low-volume center. Complications and mortality rates were lower in patients who were managed at high-volume centers and urban hospitals, while no difference was noticed based on teaching status. On regression analysis, patients managed at high-volume centers (OR 0.76 [0.56-0.89]) and urban hospitals (OR 0.83 [0.64-0.91]) have lower odds of complications; similarly, high-volume centers (OR 0.79 [0.65-0.90]) and urban facility (OR 0.87 [0.70-0.92]) were associated with lower odds of mortality. However, there was no association between teaching status and outcomes. CONCLUSION: Hospital factors significantly influence outcomes in patients with CRC managed surgically. High-volume centers and urban facilities have relatively better outcomes. Regionalization of care along with the appropriate availability of resources may improve outcomes in patients with CRC. LEVEL OF EVIDENCE: Level III, Retrospective Observational Study.

BACKGROUND: The incidence in young patients has increased significantly over the last few decades. The aim of this study is to evaluate demographic and tumor characteristics of young patients and analyze the short-term surgical outcomes of patients undergoing surgery. METHODS: We performed a 2-year review (2015-2016) of the ACS-NSQIP and included all patients with CC who underwent surgical management. Patients were stratified into two groups: early-onset CC (< 50 years old) and late-onset CC (≥ 50 years old). Outcome measures were hospital length of stay, 30-day complications, mortality, and readmission. RESULTS: We included a total of 15,957 patients in the analysis. Mean age was 65 ± 13 years, and 52% were male. Overall 10% of the patients had early-onset CC. Patients with early-onset CC were more likely to be black (11% vs 7%, p = 0.04) and Hispanic (8% vs 4%, p = 0.02). Additionally, they presented with a more aggressive tumor and higher TNM staging. Patients with early onset CC had lower 30-day complications (18% vs 22%, p = 0.02), shorter hospital length of stay (6[3-8] vs 8[5-11], p = 0.03) and lower 30-day mortality (0.4% vs 1.8%, p = 0.04) compared to their counterparts. However, there was no difference between the two groups regarding 30-day readmission. On regression analysis, there was no difference between the two groups regarding study outcomes. CONCLUSIONS: Racial disparity does exist in the incidence of colon cancer in the young with higher incidence in blacks. Younger patients with CC tend to have better surgical outcomes on univariate analysis. On regression analysis, the surgical outcomes between the two groups are comparable.

BACKGROUND: Rectal cancer (RC) among young patients (≤50 years) is on the rise. The factors associated with development of RC are established however; factors leading to early RC remain unclear. The aim of this study was to assess factors associated with RC among young patients. METHODS: National estimates for patients with RC were abstracted from the National Inpatient Sample (NIS) database [2010-2012]. Patients were divided into two groups: young (≤50 years) and old (>50 years). Demographic, comorbidities, procedures performed, and hospital outcomes were collected. Regression analysis was performed to compare both groups. RESULTS: A total of 68,699 patients with RC were included. Incidence of RC among young patients increased significantly over the study period (2.4% vs. 3.4%; P=0.04). Majority of young patients with RC were white females. Bleeding was the most common presentation among young patients (P=0.03). Younger patients were more likely to have a family history of RC (P=0.01) and were more likely to undergo elective surgery (P=0.04) and laparoscopic surgery (P=0.02) compared to the older patients. Younger patients with RC were also more likely to use alcohol (P=0.03), be obese (P=0.02) compared to elder patients. There was no difference in the other co-morbidities between the two groups. After controlling for all factors in a regression model, younger patients had a lower complication rate (P=0.01), hospital LOS (P=0.02), and mortality rate (P=0.04). CONCLUSIONS: RC in younger patients appears as a different disease with different outcomes. There appears to be multifactorial and environmental factors contributing to this trend. Race and gender also play a role in the incidence of RC in the young. Identifying these risk factors will lead to a more robust intervention plan to help improve care among younger patients with RC.
RESUMO
BACKGROUND: Colorectal cancer (CRC) is the third most commonly diagnosed cancer and the second leading cause of cancer related deaths in the United States. Racial disparities between Hispanics and Whites exist for incidence of late-onset (LO) CRC. However, not much is known about potential disparities between colon cancer (CC) and rectal cancer (RC) incidence queried individually. METHODS: Using the SEER database data from 2000 to 2010, we obtained the national estimates of CC and RC for Hispanics and Whites. We analyzed trends in incidence, mortality, gender and stage of disease for early-onset (EO) (<50 years old) and LO (>50 years old) CC and RC. RESULTS: In Hispanics, the overall incidence of CC and RC increased by 47% and 52%, respectively; while in Whites, the overall incidence of CC and RC decreased by 13% and 2% respectively. Incidence of EO CC increased in both Hispanics and Whites by 83% and 17%, respectively, and incidence of EO RC also increased for both groups with a 76% increase in Hispanics and a 34% increase in Whites. For LO CC, the incidence increased by 37% in Hispanics while it decreased by 17% in Whites and for LO RC, the trend in incidence increased in Hispanics by 41%, but decreased in Whites by 11%. CONCLUSIONS: This study established that the incidence of CC and RC are different and there is racial disparity in incidence between Whites and Hispanics. This study, hopefully, will help in crafting public policy that might help in addressing this disparity.
RESUMO
BACKGROUND: Return of bowel function (ROBF) after abdominal surgery is an important determinant of patient outcomes. The role of intraoperative fluids (IOFs) in colon surgery remains unclear. The aim of this study was to assess the impact of IOF on ROBF in patients undergoing colon surgery. We hypothesized that minimizing IOFs allows earlier ROBF. METHODS: A 2-year (2016-2017) retrospective analysis of all patients undergoing elective colon resection was performed at our tertiary hospital using a protocol limiting IOF and postoperative narcotics. Patients were divided into two groups: preprotocol (2016) and postprotocol (PoP) (2017). Patients were matched using propensity score matching for age, gender, comorbidities, Anesthesiology Severity Score, indication for procedure, and procedure type. The outcome measured was ROBF. Secondary outcome measures were complication rates and hospital length of stay. RESULTS: A total of 360 patients were analyzed. After propensity matching, 90 patients (preprotocol: 45; PoP: 45) were included. The mean age was 62.2 ± 14.8 y, 43.3% male, and 44.4% of procedures were performed laparoscopically. There was no difference in demographics and comorbidities between groups. PoP patients received lower IOF (P = 0.036, 2016: 1198.8 ± 1096.5 mL, 2017: 2176.7 ± 1458.3 mL) and lower postoperative narcotics (P = 0.042). PoP patients had earlier ROBF 2[2-4], 4[3-5] (odds ratio: 1.18 [1.05-1.52], P = 0.04), shorter length of stay 3[2-5] d versus 5[4-7] (odds ratio: 1.11 [1.09-1.89], P = 0.043), and trended toward lower complication rates (P = 0.09). CONCLUSIONS: IOF volume independently impacts ROBF after colon surgery. Restricting IOF allows for earlier bowel function and shorter hospital stay. Further studies defining optimum fluid management impacting ROBF may help optimize patient care.
