Body composition parameters in initial CT imaging of mechanically ventilated trauma patients: Single-centre observational study. J Cachexia Sarcopenia Muscle 2024. [PMID: 39185615 DOI: 10.1002/jcsm.13578] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/05/2024] [Revised: 06/13/2024] [Accepted: 08/06/2024] [Indexed: 08/27/2024] Open
Abstract
BACKGROUND Body composition parameters provide relevant prognostic significance in critical care cohorts and cancer populations. Published results regarding polytrauma patients are inconclusive to date. The goal of this study was to analyse the role of body composition parameters in severely injured trauma patients. METHODS All consecutive patients requiring emergency tracheal intubation and mechanical ventilation before initial computed tomography (CT) at a level-1 trauma centre over a 12-year period (2008-2019) were reanalysed. The analysis included CT-derived body composition parameters based upon whole-body trauma CT as prognostic variables for 30-day mortality, intensive care unit length of stay (ICU LOS) and mechanical ventilation duration. RESULTS Four hundred seventy-two patients (75% male) with a median age of 49 years, median injury severity score of 26 and 30-day mortality rate of 22% (104 patients) met the inclusion criteria and were analysed. Regarding body composition parameters, 231 patients (49%) had visceral obesity, 75 patients had sarcopenia (16%) and 35 patients had sarcopenic obesity (7.4%). After adjustment for statistically significant univariable predictors age, body mass index, sarcopenic obesity, visceral obesity, American Society of Anesthesiologists classification ≥3, injury severity score and Glasgow Coma Scale ≤ 8 points, the Cox proportional hazard model identified sarcopenia as significant prognostic factor of 30-day mortality (hazard ratio 2.84; 95% confidence interval 1.38-5.85; P = 0.004), which was confirmed in Kaplan-Meier survival analysis (log-rank P = 0.006). In a subanalysis of 363 survivors, linear multivariable regression analysis revealed no significant associations of body composition parameters with ICU LOS and duration of mechanical ventilation. CONCLUSIONS In a multivariable analysis of mechanically ventilated trauma patients, CT-defined sarcopenia was significantly associated with 30-day mortality whereas no associations of body composition parameters with ICU LOS and duration of mechanical ventilation were observed.

Sarcopenia is independently associated with poor preoperative physical fitness in patients undergoing colorectal cancer surgery. J Cachexia Sarcopenia Muscle 2024. [PMID: 38925534 DOI: 10.1002/jcsm.13536] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/20/2023] [Revised: 04/05/2024] [Accepted: 06/03/2024] [Indexed: 06/28/2024] Open
Abstract
BACKGROUND Accurate preoperative risk assessment for major colorectal cancer (CRC) surgery remains challenging. Body composition (BC) and cardiopulmonary exercise testing (CPET) can be used to evaluate risk. The relationship between BC and CPET in patients undergoing curative CRC surgery is unclear. METHODS Consecutive patients undergoing CPET prior to CRC surgery between 2010 and 2020 were identified between two different UK hospitals. Body composition phenotypes such as sarcopenia, myosteatosis, and visceral obesity were defined using widely accepted thresholds using preoperative single axial slice CT image at L3 vertebrae. Relationships between clinicopathological, BC, and CPET variables were investigated using linear regression analysis. RESULTS Two hundred eighteen patients with stage I-III CRC were included. The prevalence of sarcopenia, myosteatosis, and visceral obesity was 62%, 33%, and 64%, respectively. The median oxygen uptake at anaerobic threshold (VO2 at AT) was 12.2 mL/kg/min (IQR 10.6-14.2), and oxygen uptake at peak exercise (VO2 peak) was 18.8 mL/kg/min (IQR 15.4-23). On univariate linear regression analysis, male sex (P < 0.001) was positively associated with VO2 at AT. While ASA grade (P < 0.001) and BMI (P = 0.007) were negatively associated with VO2 at AT, on multivariate linear regression analysis, these variables remained significant (P < 0.05). On univariate linear regression analysis, male sex (P < 0.001) was positively associated with VO2 peak, whereas age (P < 0.001), ASA grade (P < 0.001), BMI (P = 0.003), sarcopenia (P = 0.015), and myosteatosis (P < 0.001) were negatively associated with VO2 peak. On multivariate linear regression analysis age (P < 0.001), ASA grade (P < 0.001), BMI (P < 0.001), and sarcopenia (P = 0.006) were independently and negatively associated with VO2 peak. CONCLUSIONS The novel finding that sarcopenia is independently associated with reduced VO2 peak performance in CPET supports the supposition that reduced muscle mass relates to poor physical function in CRC patients. Further work should be undertaken to assess whether sarcopenia diagnosed on CT can act as suitable surrogate for CPET to further enhance personalized risk stratification.

Abstract
OBJECTIVE The prognostic significance of a low visceral fat area (VFA) in colorectal cancer (CRC) remains unclear. The aim of this study was to evaluate the prognostic effects of a low VFA on the long-term outcomes of patients with CRC after laparoscopic surgery. METHODS This retrospective study included 306 patients with stages I-III CRC who underwent R0 resection. VFA was preoperatively measured via computed tomography using image processing software. Relapse-free survival (RFS) and overall survival (OS) rates were analyzed using the Cox proportional hazards model and Kaplan-Meier curves. RESULTS Low VFA was identified in 153 patients. The low VFA group had significantly lower RFS and OS rates than did the high VFA group (5-y RFS rates: 72 versus 89%, P = 0.0002; 5-y OS rates: 72 versus 92%, P = 0.0001). The independent significant predictors of RFS were T3 or T4 disease (hazard ratio [HR], 2.75; 95% confidence interval [CI], 1.12-6.76; P = 0.027), stage III CRC (HR, 3.49; 95% CI, 1.82-6.69; P < 0.001), low psoas muscle index (PMI; HR, 2.12; 95% CI, 1.19-3.79; P = 0.011), and low VFA (HR, 2.12; 95% CI, 1.16-3.86; P = 0.014). The independent significant predictors of OS were age ≥65 y (HR, 2.59; 95% CI, 1.13-5.92, P = 0.024), carbohydrate antigen 19-9 levels ≥37 ng/mL (HR, 2.32; 95% CI, 1.18-4.58; P = 0.015), stage III CRC (HR, 2.66; 95% CI, 1.37-5.17; P = 0.004), low PMI (HR, 2.00; 95% CI, 1.06-3.77; P = 0.031), and low VFA (HR, 2.42; 95% CI, 1.24-4.70; P = 0.009). CONCLUSION A low preoperative VFA was significantly associated with worse RFS and OS rates in patients who underwent CRC resection.

Abstract
Rectal cancer is one of the most prevalent cancers that arise in the digestive tract. The purpose of this retrospective study was to investigate the impact of visceral fat area (VFA) on postoperative outcomes in mid and low rectal cancer patients undergoing robotic surgery (RS). Data were collected on patients who underwent robotic anterior rectal resection in a single center from December 2019 to October 2023. Clinical pathology information was analyzed. Statistical analysis was done on the computed tomography (CT) imaging data. A total of 277 patients were included in the study, including 121 cases with visceral obesity (VO) and 156 cases without VO. There was no statistically significant disparity in the lymph node dissection count, blood loss, duration of hospitalization, time to first liquid diet, early postoperative complications, histopathologic specimen indices (quality of TME and CRM involvement rate), and or the rate of conversion to open surgery between VO and non-VO group (P > 0.05). Nevertheless, the group of individuals with VO experienced a lengthier duration of surgery (P < 0.001) and a delayed time until the first passage of flatus (P < 0.001) in comparison to the group without VO. The study suggests that VO does not significantly impact early complications or the quality of surgical outcomes in mid and low rectal cancer patients undergoing robotic surgery. The findings support the continued use of RS as an optimal strategy for technically demanding patients.

Abstract
BACKGROUND Visceral obesity, a strong indicator of chronic inflammation and impaired metabolic health, has been shown to be associated with poor postoperative outcomes and complications. This study aimed to evaluate the relationship between visceral fat area (VFA) and periprosthetic joint infection (PJI) in total joint arthroplasty (TJA) patients. METHODS A retrospective study of 484 patients who had undergone a total hip or knee arthroplasty was performed. All patients had a computed tomography scan of the abdomen/pelvis within two years of their TJA. Body composition data (ie, VFA, subcutaneous fat area, and skeletal muscle area) were calculated at the Lumbar-3 vertebral level via two fully automated and externally validated machine learning algorithms. A multivariable logistic model was created to determine the relationship between VFA and PJI, while accounting for other PJI risk factors. Of the 484 patients, 31 (6.4%) had a PJI complication. RESULTS The rate of PJI among patients with VFA in the top quartile (> 264.1 cm2) versus bottom quartile (< 82.6 cm2) was 5.6% versus 10.6% and 18.8% versus 2.7% in the total hip arthroplasty and total knee arthroplasty cohorts, respectively. In the multivariate model, total knee arthroplasty patients with a VFA in the top quartile had a 30.5 times greater risk of PJI than those in the bottom quartile of VFA (P = .0154). CONCLUSION VFA may have a strong association with PJI in TJA patients. Using a standardized imaging modality like computed tomography scans to calculate VFA can be a valuable tool for surgeons when assessing risk of PJI.

Abstract
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.

Front Nutr 2023; 10:1126127. [PMID: 37260520 PMCID: PMC10228740 DOI: 10.3389/fnut.2023.1126127] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2022] [Accepted: 04/10/2023] [Indexed: 06/02/2023] Open
Abstract
Background The influence of body composition on the outcome of colorectal cancer surgery is controversial. The aim of this study was to evaluate the effects of visceral obesity and sarcobesity on the incidence of total and surgical complications after radical resection of colorectal cancer. Methods We collected a total of 426 patients who underwent elective radical resection of colorectal cancer at Beijing Friendship Hospital, Capital Medical University from January 2017 to May 2018. According to the inclusion and exclusion criteria, 387 patients were finally included. A CT scan at the level of the L3-L4 intervertebral disk was selected to measure the values of visceral fat area and skeletal muscle area. Multivariate analysis was used to explore the independent risk/protective factors affecting postoperative complications. Results 128 (33.1%) patients developed complications, and 44 (11.4%) patients developed major complications. Among them, 111 patients developed surgical complications and 21 developed medical complications. Visceral fat area (Z = -3.271, p = 0.001), total fat area (Z = -2.613, p = 0.009), visceral fat area to subcutaneous fat area ratio (V/S, Z = -2.633, p = 0.008), and sarcobesity index (Z = -2.282, p = 0.023) were significantly associated with total complications. Visceral fat area (Z = -2.119, p = 0.034) and V/S (Z = -2.010, p = 0.044) were significantly associated with total surgical complications. Sarcobesity index, smoking, stoma, blood loss, surgery time, and American Society of Anesthesiology (ASA) score were selected as risk factors for total postoperative complications according to LASSO regression. Multivariate logistic regression analysis suggested that sarcobesity index was an independent risk factor for postoperative total complications and surgical complications. Subgroup analysis suggested that albumin level was an independent protective factor for postoperative total complications in male patients. Smoking, operative time, and sarcobesity index were independent risk factors, and cholesterol was an independent protective factor for total postoperative complications in female patients. Conclusion Increased sarcobesity index is an independent risk factor for postoperative complications in patients with colorectal cancer, while visceral fat area is not. For female patients, smoking, operation time, and obesity index are independent risk factors for postoperative complications, while cholesterol is an independent protective factor. For male patients, serum albumin is an independent protective factor for postoperative complications.

Jones A, Silver HJ. Myosteatotic and sarcopenic obesity impact postoperative outcomes more robustly than visceral obesity in general surgery patients, with differences by sex. Clin Nutr 2023; 42:625-635. [PMID: 36947987 DOI: 10.1016/j.clnu.2023.03.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2022] [Revised: 03/02/2023] [Accepted: 03/06/2023] [Indexed: 03/24/2023]
Abstract
BACKGROUND AND AIMS Computed tomography (CT) defined myosteatotic, sarcopenic, and visceral obesity are associated with adverse surgical outcomes and mortality in patients with malignancies. These occult conditions may also be widely prevalent in today's general surgery patients who tend to be overweight/obese. This study identified the predominant obesity phenotypes in 906 patients aged 18-85 years who were scheduled for laparoscopic resection for benign abdominal or colorectal disease at Vanderbilt University Medical Center between 2010 and 2017. METHODS Sex and body mass index (BMI) specific cut-points were used to identify myosteatotic, sarcopenic, and visceral obesity phenotype from abdominal CT scan morphometrics. Multivariable regression modeling determined relationships between sex, obesity phenotype, and postoperative outcomes. RESULTS The myosteatostic + sarcopenic obesity phenotype associated with longer surgery duration and increased the likelihood for major complication (OR 1.34, 95%CI 1.01-1.74) and ICU admission (OR 1.39, 95%CI 1.04-1.90). Having myosteatotic obesity doubled the likelihood for hospital stay >7 days and discharge to a nursing home (OR 2.11, 95%CI 1.43,3.11), increasing the likelihood for readmission within 90 days. Obesity was more prevalent in females, but myosteatotic, sarcopenic, and visceral obesity were more prevalent in males, regardless of age or BMI. Males had more major complications (23.6% vs 17.7%, P = 0.03), particularly wound dehiscence or infection, and a 2-day longer hospital stay. CONCLUSIONS This study shows that sarcopenic and myosteatotic obesity phenotypes are highly prevalent, especially in male general surgery patients, regardless of age or BMI. Importantly, sarcopenic and myosteatostic obesity may be more detrimental than visceral obesity; these phenotypes robustly associated with adverse postoperative outcomes. Future work could use these findings for design of phenotype-specific interventions to reduce patient risk and prevent outcomes that are harmful and costly.

Sarcopenia is an independent risk factor for failure to achieve the 1-year MCID of the KOOS, JR and PROMIS PF-SF10a after TKA. Knee 2023; 42:64-72. [PMID: 36913864 DOI: 10.1016/j.knee.2023.02.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/01/2022] [Revised: 02/07/2023] [Accepted: 02/28/2023] [Indexed: 03/15/2023]
Abstract
BACKGROUND Sarcopenia, which is a progressive and multifactorial condition of decreased muscle strength, has been identified as an independent predictor for falls, revision, infection, and readmissions following total knee arthroplasty (TKA), but its association to patient reported outcomes (PROMs) is less studied. The aim of this study is to determine if sarcopenia and other measures of body composition are correlated with ability to achieve the 1-year minimal clinically important difference (MCID) of the KOOS JR and PROMIS-PF-SF10a following primary TKA. METHODS A multicenter retrospective case-control study was performed. Inclusion criteria consisted of patients over the age of 18 undergoing primary TKA, body composition metrics determined by computed tomography (CT), and available pre- and post-operative PROM scores. Predictors of achievement of the 1-year MCID of the KOOS JR and PROMIS PF-SF-10a were determined through a multivariate linear regression. RESULTS 140 primary TKAs met inclusion criteria. 74 (52.85%) patients achieved the 1-year KOOS, JR MCID and 108 (77.41%) patients achieved the 1-year MCID for the PROMIS PF-SF10a. Sarcopenia was independently associated with decreased odds of achieving the MCID of both the KOOS, JR (OR 0.31, 95%CI 0.10-0.97, p = 0.04) and the PROMIS-PF-SF10a (OR 0.32, 95%CI 0.12-0.85, p = 0.02) CONCLUSIONS: In our study, sarcopenia was independently associated with increased odds of failure to achieve the 1-year MCID of the KOOS, JR and PROMIS PF-SF10a after TKA. Early identification of sarcopenic patients may be beneficial for arthroplasty surgeons so that targeted nutritional counseling and exercises can be recommended prior to TKA.

Advantage of laparoscopic surgery in patients with generalized obesity operated for colorectal malignancy: A retrospective cohort study. Front Surg 2023; 9:1062746. [PMID: 36684184 PMCID: PMC9852741 DOI: 10.3389/fsurg.2022.1062746] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2022] [Accepted: 11/21/2022] [Indexed: 01/07/2023] Open
Abstract
Background Because of the progression of minimally invasive surgery skills and obesity in colorectal surgery, we aimed to evaluate the short-term outcomes of colorectal cancer resections in patients with generalized obesity at a single teaching hospital with mature surgical techniques and training programs. Methods A total of 537 patients were diagnosed with CRC and had a body mass index ≥30 kg/m2 between January 2009 and December 2019 at a single institution. 265 patients underwent open surgery and 272 patients underwent laparoscopic surgery. Data were analysed to explore the independent risk factors for postoperative complications. Results The laparoscopic group had less blood loss (73 ± 128 vs. 148 ± 290 ml, p < 0.001) and a shorter postoperative hospital stay (10.8 ± 17.1 vs. 11.7 ± 6.8 days, p < 0.001) than the open group. The number of harvested lymph nodes did not significantly differ between the two groups (30.9 ± 18.3 vs. 30.2 ± 15.3, p = 0.981). Although anastomotic leakage was significantly higher in the laparoscopic group (1.5% vs. 4.8%, p = 0.030), there were also similar overall postoperative morbidity and mortality rates between the open and laparoscopic groups for CRC patients with generalized obesity who underwent surgery. Conclusion Laparoscopic surgery can reduce blood loss, decrease the length of hospital stay, obtain a similar number of harvested lymph nodes, and achieve an acceptable conversion rate for CRC patients with generalized obesity. We suggest that laparoscopic surgery could become a standard method for CRC treatment in patients with generalized obesity.

Impact of adipose tissue distribution on prostate cancer recurrence after radical prostatectomy. ACTAS UROLÓGICAS ESPAÑOLAS (ENGLISH EDITION) 2022; 47:104-110. [PMID: 37078845 DOI: 10.1016/j.acuroe.2022.06.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/14/2021] [Accepted: 12/19/2021] [Indexed: 11/06/2022]
Abstract
OBJECTIVE The aim of our study is to correlate the CT adipose tissue distribution and recurrence risk of Prostatic Cancer (PCa) after Radical Prostatectomy (RP). Furthermore, we evaluated the association of adipose tissue and PCa aggressiveness. MATERIALS AND METHODS We identified two groups of patients based on presence (group A) and absence (group B or control group) of Bio-chemical Recurrence (BCR) after RP. A semi-automatic function able to recognize the typical attenuation values of adipose tissue was used for sub-cutaneous (SCAT), visceral (VAT), total (TAT) and periprostatic (PPAT) adipose tissues. For both groups of patients, a descriptive analysis of continuous variables and categorical variables was performed. RESULTS After comparing between groups, a statistically significant difference was found for VAT (p<0.001) and for VAT/TAT ratio (p=0.013). No statistically significant correlation was found for PPAT and SCAT, even if higher values were found in patients with high grade tumors. CONCLUSION This study confirms visceral adipose tissue as a quantitative imaging parameter related to oncological risk of PCa recurrence development, and the role of abdominal fat distribution measured with CT before RP as an important tool to predict the PCa recurrence risk, particularly in patients with high grade tumors.

Abstract
Objective This study evaluated the association between body composition and clinical parameters and prognosis in patients with colorectal cancer (CRC) treated by radical resection. Methods Baseline data on patient age, body mass index (BMI), bowel obstruction and tumor-related factors were collected retrospectively. Body composition parameters such as visceral fat area (VFA), total abdominal muscle area (TAMA), muscle attenuation (MA), posterior renal fat thickness (PPNF) and intermuscular fat area (IMF) are measured using Computed tomography (CT) scans. We also propose a new predictor of linear skeletal muscle index (LSMI) that can be easily measured clinically at CT. Follow-up endpoints were disease-free survival and all-cause death. We follow up with patients in hospital or by telephone. Univariate and multifactorial Cox proportional hazards analyses were performed to identify risk factors associated with prognosis. Survival analysis was performed using the Kaplan-Meier method and a nomogram was established to predict survival. Results A total of 1761 patients (median age 62 years) with CRC were enrolled in our study, of whom 201 had intestinal obstruction and 673 had a BMI > 24.0. Among all patients, the 3- and 5-year disease-free survival rates were 84.55% and 68.60% respectively, and the overall survival rates were 88.87% and 76.38%. Overall survival was significantly correlated with MA, LSMI, SMI, Tumor size, N stage, metastasis and adjuvant therapy by Cox regression analysis (p < 0.05). The risk of tumor progression was significantly associated with MA, VFA, LSMI, SMI, Male, N stage, metastasis and adjuvant therapy (p < 0.05). In addition, based on the Chinese population, we found that female patients with MA < 30.0 HU, LSMI < 18.2, and SMI < 38.0 had a worse prognosis, male patients with MA < 37.6 HU, LSMI < 21.9, and SMI < 40.3 had a poorer prognosis. Conclusion Our findings suggest that linear skeletal muscle index and MA can be used as new independent predictors for colorectal cancer patients treated with radical surgery, and that baseline data such as body composition parameters, LSMI and tumor-related factors can collectively predict patient prognosis. These results could help us to optimize the management and treatment of patients after surgery.

Distance of Peritoneum to Inferior Mesenteric Artery Predicts the Operation Time During Laparoscopic Colectomy for Sigmoid or Rectosigmoid Colon Cancer. CANCER DIAGNOSIS & PROGNOSIS 2022; 2:240-246. [PMID: 35399172 PMCID: PMC8962805 DOI: 10.21873/cdp.10100] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/16/2021] [Accepted: 01/07/2022] [Indexed: 06/14/2023]
Abstract
BACKGROUND/AIM Obesity is a major technical limiting factor for laparoscopic surgery because abundant visceral fat is known to extend the operation time. However, special hardware is needed to assess it. We hypothesized that the depth from the peritoneum to the bifurcation of the inferior mesenteric artery (IMA) defined as 'peritoneum to IMA distance (PID)' might be a simple predictive factor for extended operation time during laparoscopic colectomy. PATIENTS AND METHODS One hundred twenty-four patients who were diagnosed with sigmoid or rectosigmoid colon cancer and underwent laparoscopic colectomy were included. The patients were divided into two groups based on the operation time (210 min). The vertical distance from the peritoneum to the bifurcation of the inferior mesenteric artery was defined as PID. The factors eliciting an operation time longer than 210 min were investigated. RESULTS There was significant difference in sex, BMI, cT, cN, and PID between the Early group (<210 min) and Late group (≥210 min). Less blood loss was observed in the Early group than in the Late group. Multivariate analysis showed that PID was the only independent factor that affected operation time (p<0.001). CONCLUSION PID predicts the operation time during laparoscopic colectomy for sigmoid or rectosigmoid colon cancer.

Abstract
INTRODUCTION Surgery for colorectal cancer is associated with post-operative morbidity and mortality. Multiple systematic reviews have reported on individual factors affecting short-term outcome following surgical resection. This umbrella review aims to synthesize the available evidence on host and other factors associated with short-term post-operative complications. METHODS A comprehensive search identified systematic reviews reporting on short-term outcomes following colorectal cancer surgery using PubMed, Cochrane Database of Systematic Reviews and Web of Science from inception to 8th September 2020. All reported clinicopathological variables were extracted from published systematic reviews. RESULTS The present overview identified multiple validated factors affecting short-term outcomes in patients undergoing colorectal cancer resection. In particular, factors consistently associated with post-operative outcome differed with the type of complication; infective, non-infective or mortality. A minimum dataset was identified for future studies and included pre-operative age, sex, diabetes status, body mass index, body composition (sarcopenia, visceral obesity) and functional status (ASA, frailty). A recommended dataset included antibiotic prophylaxis, iron therapy, blood transfusion, erythropoietin, steroid use, enhance recovery programme and finally potential dataset included measures of the systemic inflammatory response CONCLUSION: A minimum dataset of mandatory, recommended, and potential baseline variables to be included in studies of patients undergoing colorectal cancer resection is proposed. This will maximise the benefit of such study datasets.

Abstract
BACKGROUND This is a study aimed at exploring the relationship between pretreatment overweight/obesity, adipose tissue distribution, and long-term prognosis of gastric cancer. METHODS A total of 607 gastric cancer patients were involved in the retrospective cohort study. Overweight/obese patients were defined as body mass index (BMI) greater than 25 kg/m2, and adipose tissue distribution parameters, including visceral adipose tissue (VAT), subcutaneous adipose tissue (SAT), and VAT/SAT ratio were measured at the level of the third lumbar vertebra using computerized tomography images within 15 days before the surgery. Multiple Cox regression models were applied to evaluate the association between overweight/obesity and disease-specific survival (DSS) of gastric cancer, and covariates including age, gender, T stage, N stage, and chemotherapy were adjusted. Furthermore, multiple Cox regression models were performed to evaluate the association between adipose tissue distribution parameters and DSS of gastric cancer; except for covariates mentioned above, overweight/obesity was adjusted additionally. RESULTS Overweight/obesity was a predictive factor (HR = 0.61, 95% CI: 0.37-0.99) for the prognosis of gastric cancer. After additionally adjusting for overweight/obesity, high SAT percentage was an independent protective factor (HR = 0.59, 95% CI: 0.36-0.96), while high VAT percentage (HR = 1.68, 95% CI: 1.06-2.68) and high VAT/SAT ratio (HR = 1.99, 95% CI: 1.19-3.34) were independent risk factors for DSS of gastric cancer. Compared with other patients (overweight/obesity with low VAT/SAT ratio group, non-overweight/obesity or high VAT/SAT ratio group), patients in the non-overweight/obesity with high VAT/SAT ratio group had a worse prognosis (HR = 1.89, 95% CI: 1.28-2.77). CONCLUSION These results suggest that overweight/obesity is a predictive factor for the prognosis of gastric cancer. The VAT/SAT ratio could be used as a promising prognostic factor for gastric cancer. Therefore, in preoperative evaluation of gastric cancer patients, attention should be paid not only to BMI but also to adipose tissue distribution.

Abstract
Background The impact of body compositions on surgical results is controversially discussed. This study examined whether visceral obesity, sarcopenia or sarcopenic obesity influence the outcome after hepatic resections of synchronous colorectal liver metastases. Methods Ninety-four consecutive patients with primary hepatic resections of synchronous colorectal metastases were identified from a single center database between January 2013 and August 2018. Patient characteristics and 30-day morbidity were retrospectively analyzed. Body fat and skeletal muscle were calculated by planimetry from single-slice CT images at the level of L3. Results Fifty-nine patients (62.8%) underwent minor hepatectomies, and 35 patients underwent major resections (37.2%). Postoperative complications occurred in 60 patients (62.8%) including 35 patients with major complications (Clavien–Dindo grade III–V). The mortality was nil at 30 days and 2.1% at 90 days. The body mass index showed no influence on postoperative outcomes (p = 1.0). Visceral obesity was found in 66 patients (70.2%) and was significantly associated with overall and major complication rates (p = .002, p = .012, respectively). Sarcopenia was observed in 34 patients (36.2%) without a significant impact on morbidity (p = .461), however, with longer hospital stay. Sarcopenic obesity was found in 18 patients (19.1%) and was significantly associated with postoperative complications (p = .014). Visceral obesity, sarcopenia and sarcopenic obesity were all identified as significant risk factors for overall postoperative complications. Conclusion Visceral obesity, sarcopenic obesity and sarcopenia are independent risk factors for overall complications after resections of CRLM. Early recognition of extremes in body compositions could prompt to perioperative interventions and thus improve postoperative outcomes.

Abstract
BACKGROUND There is an increasing interest in studying the impact of altered body composition parameters and colorectal cancer (CRC) treatment outcomes. The aim of this study is to explore the impact of computed tomography (CT)-measured visceral obesity, sarcopenia and myosteatosis on survival of non-metastatic CRC. METHODS Consecutive patients with stage I-III CRC who underwent curative-intent treatment between January 2010 and December 2015 were included. By measuring the visceral fat area, and the skeletal muscle index and radiodensity in the pre-operative staging CT, patients were classified as visceral obese, sarcopenic or myosteatotic. The associations between CT-based body composition parameters and survival were assessed using log-rank tests and a Cox regression analysis. RESULTS Of 359 patients, 263 (73.3%) were visceral obese, 85 (23.7%) sarcopenic and 80 (22.3%) myosteatotic. Overall (OS), cancer-specific (CSS) and disease-free survivals (DFS) at 5 years were 78.8%, 84.7% and 75%, respectively. Myosteatosis and the combination of myosteatosis and visceral obesity were associated with a reduced DFS (hazard ratio 1.67; 95% confidence interval 1.06-2.61 and hazard ratio 1.85; 95% confidence interval 1.15-2.96, respectively). However, after performing a multivariate analysis including other relevant clinicopathological factors, none of the body composition parameters were associated with any long-term outcome measures, even after stratifying by cancer stage. CONCLUSIONS CT-measured body composition parameters do not independently influence survival in non-metastatic CRC. There is a need for larger cohort studies with standardized patient selection and methodology to confirm these findings.

Impact of obesity in colorectal endoscopic submucosal dissection: single-center retrospective cohort study. BMC Gastroenterol 2021; 21:74. [PMID: 33593282 PMCID: PMC7885483 DOI: 10.1186/s12876-021-01652-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/17/2020] [Accepted: 02/02/2021] [Indexed: 12/28/2022] Open
Abstract
BACKGROUND When performing colorectal endoscopic submucosal dissection (ESD) in obese patients, technically difficult cases are sometimes experienced because of difficulty with the insertion of the colonoscope, poor scope maneuverability, or an abundance of fat tissue in the submucosal layer. Since the association between obesity and colorectal ESD has not been investigated, we evaluated the clinical impact of obesity in patients who underwent colorectal ESD. METHODS We retrospectively reviewed 535 patients who underwent colorectal ESD between April 2012 and February 2019. Patients were divided into three groups based on their body mass index (BMI): a control group (BMI < 25 kg/m2), an overweight group (25 kg/m2 ≤ BMI < 30 kg/m2), and an obese group (BMI ≥ 30 kg/m2), and the short-term clinical outcomes were analyzed to assess the safety and difficulty of colorectal ESD. RESULTS No significant difference in the procedure times, en bloc resection rates, pathological diagnoses, or complications were seen among the groups. While the amount of sedative per body weight was significantly lower in the group with a higher BMI (flunitrazepam: 1.75 × 10-2 [1.27 × 10-2-2.34 × 10-2] mg/kg vs. 1.48 × 10-2 [1.08 × 10-2-2.03 × 10-2] mg/kg vs. 1.16 × 10-2 [0.98 × 10-2-1.54 × 10-2] mg/kg, P < 0.001; pethidine: 0.63 [0.55-0.72] mg/kg vs. 0.50 [0.46-0.56] mg/kg vs. 0.39 [0.32-0.45] mg/kg, P < 0.001), a reduction in percutaneous arterial oxygen saturation occurred significantly more frequently in the group with a higher BMI (123 [30.2%] vs. 43 [43.9%] vs. 10 [55.6%], P = 0.005). When the procedures were performed by trainees, the number of cases that required a procedure time of longer than 90 min was significantly larger in the group with a higher BMI (27 [10.8%] vs. 14 [21.9%] vs. 3 [25.0%], P = 0.033). CONCLUSIONS This study showed that colorectal ESD could be performed safely and effectively in obese patients. However, ESD in obese patients requires attention, particularly to changes in respiratory conditions.

Abstract
Importance Given the risks of postoperative morbidity and its consequent economic burden and impairment to patients undergoing colon resection, evaluating risk factors associated with complications will allow risk stratification and the targeting of supportive interventions. Evaluation of muscle characteristics is an emerging area for improving preoperative risk stratification. Objective To examine the associations of muscle characteristics with postoperative complications, length of hospital stay (LOS), readmission, and mortality in patients with colon cancer. Design, Setting, and Participants This population-based retrospective cohort study was conducted among 1630 patients who received a diagnosis of stage I to III colon cancer from January 2006 to December 2011 at Kaiser Permanente Northern California, an integrated health care system. Preliminary data analysis started in 2017. Because major complication data were collected between 2018 and 2019, the final analysis using the current cohort was conducted between 2019 and 2020. Exposures Low skeletal muscle index (SMI) and/or low skeletal muscle radiodensity (SMD) levels were assessed using preoperative computerized tomography images. Main Outcomes and Measures Length of stay, any complication (≥1 predefined complications) or major complications (Clavien-Dindo classification score ≥3), 30-day mortality and readmission up to 30 days postdischarge, and overall mortality. Results The mean (SD) age at diagnosis was 64.0 (11.3) years and 906 (55.6%) were women. Patients with low SMI or low SMD were more likely to remain hospitalized 7 days or longer after surgery (odds ratio [OR], 1.33; 95% CI, 1.05-1.68; OR, 1.39; 95% CI, 1.05-1.84, respectively) and had higher risks of overall mortality (hazard ratio, 1.40; 95% CI, 1.13-1.74; hazard ratio, 1.44; 95% CI, 1.12-1.85, respectively). Additionally, patients with low SMI were more likely to have 1 or more postsurgical complications (OR, 1.31; 95% CI, 1.04-1.65) and had higher risk of 30-day mortality (OR, 4.85; 95% CI, 1.23-19.15). Low SMD was associated with higher odds of having major complications (OR, 2.41; 95% CI, 1.44-4.04). Conclusions and Relevance Low SMI and low SMD were associated with longer LOS, higher risk of postsurgical complications, and short-term and long-term mortality. Research should evaluate whether targeting potentially modifiable factors preoperatively, such as preserving muscle mass, could reverse the observed negative associations with postoperative outcomes.

Abstract
OBJECTIVES Infectious morbidity is the most common and costly among all surgery-related complications, and infections by multidrug-resistant microorganisms (MDR) are associated with poor outcomes. Derangements of body composition is a recognized risk factor for infections. The aim of this study was to investigate the potential association between specific traits of body composition and the risk of having MDR-related infections. METHODS This was a prospective study with patients scheduled for major abdominal surgery for gastrointestinal cancer. Bioimpedance vector analysis (BIVA), a reliable tool for body composition assessment, was performed the day before the operation. Postoperative complications were collected focusing on resistance patterns and site of infection. Patterns of resistance were compared with BIVA parameters. RESULTS Data from 182 patients suffering from pancreatic (n = 76, 41.7%), rectal (n = 38, 20.9%), gastric (n = 31, 17%), or hepatic (n = 37, 20.3%) malignancy were collected. Overall complications occurred in 108 patients (59%), and in 45 patients (28%) bacterial infections were proven at culture. Of these, 15 (8%) were multidrug-sensitive (MDS), 38 MDR, and 2 extended drug-resistant (XDR) infections. The standardized phase angle measured (SPA) at BIVA was significantly lower in the MDR/XDR infections (-0.02 ± 1.20) than for no infection/MDS (0.56 ± 1.53; P = 0.029). A multivariate analysis showed that SPA was the only independent variable for MDR/XDR infections with an odds ratio of 3.057 (95% confidence interval, 1.354-6903; P = 0.007). The predictive ability of SPA revealed an area under the receiver operating characteristic curve of 0.662, with an optimal threshold of -0.3. CONCLUSIONS In surgical cancer patients, preoperative value of SPA lower than -0.3 is associated with the outbreak of MDR bacterial infections.

Abstract
BACKGROUND Anthropometric data as prognostic factors of colorectal cancer are promising but contradictory. The aim of this study was to assess the preoperative body composition profiles as predictive factors for postoperative, oncologic, and inflammation outcomes. OBJECTIVES We sought to assess the impact of body composition profiles on short- and long-term outcomes and on postoperative inflammatory response in a clinical setting for patients following curative intent surgery for colorectal cancer. SETTING University hopsital METHODS: We analyzed 122 patients from a prospective cohort (IMACORS) with colorectal cancer undergoing curative-intent surgery from 2011 to 2014. Musculature, total, visceral, and subcutaneous adiposity were measured from a preoperative CT scan and outcomes were compared between profiles. RESULTS Preoperative myopenia was an independent predictive factor of recurrence (HR = 3.3 95% CI = 1.6-6.9; P = .002) while subcutaneous adiposity was a protective factor (HR = .4 95% CI = .2-.9; P = .03). No anthropometric measurement was predictive of overall survival and postoperative intra abdominal infection was not determined by body composition profiles. Preoperative and D4 CRP levels were significantly higher in patients with subcutaneous adiposity. CONCLUSIONS Myopenia and subcutaneous adiposity seemed to have independent and opposite prognostic effects on recurrence. Muscle mass loss may represent a modifiable risk factor while the amount of subcutaneous adipose tissue reflects an energetic storage favorable to face this pathologic process.

Abstract
OBJECTIVE Visceral obesity (VO) is a risk factor for developing postoperative complications in patients undergoing abdominal oncological surgery. However, in ovarian cancer patients this influence of body composition on postoperative morbidity is not well established. The aim of this study is to assess the association between body composition and complications in patients with advanced ovarian cancer undergoing cytoreductive surgery. METHODS Patients with FIGO stage 3 or 4 ovarian cancer between 2006 and 2017 were included. Visceral fat area, total skeletal mass and total fat area were measured on a single slice on the level of L3-L4 of the preoperative CT-scan. VO was defined as visceral fat ≥100cm2. The perioperative data were extracted retrospectively. A multivariate logistic regression analysis was performed to test the predictive value of multiple variables such as body composition, albumin levels and preoperative morbidity. RESULTS 298 consecutive patients out of nine referring hospitals were included. VO patients were more likely to be hypertensive (38% vs 17% p < 0.001), and to have an ASA 3 score (21% vs 10% P = 0.012). Complications occurred more often in VO patients (43% vs 21% P < 0.001). Thrombotic events were found in 4.9% of VO patients versus 0.6% of the non-visceral obese patients (p = 0.019). VO(OR: 4.37, p < 0.001), hypertension (OR:1.9, p = 0.046) and duration of surgery (OR: 1.004, p = 0.017) were predictors of post-surgical complications. Muscle mass is not a predictor of complications. CONCLUSION Visceral obesity is associated with a higher occurrence of complications in patients with advanced ovarian cancer undergoing cytoreductive surgery.

The Value of Morphometric Measurements in Risk Assessment for Donor-Site Complications after Microsurgical Breast Reconstruction. J Clin Med 2020; 9:jcm9082645. [PMID: 32823954 PMCID: PMC7465816 DOI: 10.3390/jcm9082645] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2020] [Revised: 07/24/2020] [Accepted: 08/11/2020] [Indexed: 12/24/2022] Open
Abstract
Microsurgical abdominally-based reconstruction is considered the gold standard in autologous breast reconstruction. Despite refined surgical procedures, donor-site complications still occur, reducing patient satisfaction and quality of life. Recent work has outlined the potential of morphometric measurements in risk assessment for postoperative hernia development. With rising demand for personalised treatment, the goal of this study was to investigate their potential in risk assessment for any donor site complication. In this retrospective cohort study, 90 patients were included who each received microsurgical breast reconstruction at the hands of one surgeon between January 2015 and May 2017. Donor-site complications formed the primary outcome and were classified according to Clavien-Dindo. Morphometric measurements were taken on a routinely performed computed tomographic angiogram. Complications occurred in 13 of the 90 (14.4%) cases studied. All patients who developed any type of postoperative donor site complication had a history of abdominal surgery. The risk of postoperative complications increased by 3% with every square centimetre of omental fat tissue (OR 1.03, 95% CI 1.00-1.06, and p-value = 0.022). Morphometric measurements provide valuable information in risk assessment for donor-site complications in abdominally-based breast reconstruction. They may help identify personalised reconstructive options for maximal postoperative patient satisfaction and quality of life.

Abstract
Background To determine the relationship between adipose tissue and skeletal muscle measurements on computed tomography (CT) and overall survival and major postoperative complications in patients with soft-tissue sarcoma (STS). Methods The retrospective study included 137 STS patients (75 men, 62 women; mean age, 53 years, SD 17.7; mean BMI, 28.5, SD 6.6) who had abdominal CT exams. On a single CT image, at the L4 pedicle level, measurements of visceral adipose tissue (VAT), subcutaneous adipose tissue (SAT), and skeletal muscle area and attenuation were obtained using clinical PACS and specialized segmentation software. Clinical information was recorded, including STS characteristics (size, depth, grade, stage, and site), overall survival, and postoperative complications. The relationships between CT metrics and survival were analyzed using Cox proportional hazard models and those between CT metrics and postoperative complications using logistic regression models. Results There were 33 deaths and 41 major postoperative complications. Measured on clinical PACS, the psoas area (P=0.003), psoas index (P=0.006), psoas attenuation (P=0.011), and total muscle attenuation (P=0.023) were associated with overall survival. Using specialized software, psoas attenuation was also associated with overall survival (P=0.018). Adipose tissue metrics were not associated with survival or postoperative complications. Conclusions In STS patients, CT-derived muscle size and attenuation are associated with overall survival. These prognostic biomarkers can be obtained using specialized segmentation software or routine clinical PACS.

Abstract
OBJECTIVES Baseline body composition has been associated with dismal outcomes in patients undergoing a variety of major abdominal operations. Whether specific anthropometric indexes can predict morbidity after rectal resection has been poorly investigated. The aims of this study were to assess whether there is a relationship between body mass index and the different computed tomography-assessed body composition indexes, and whether the analysis of different body compartments could be predictive of short-term outcomes in patients undergoing curative surgery for rectal cancer. METHODS Computed tomography-derived measures of skeletal muscle and adipose tissue areas of patients undergoing surgery for rectal cancer between January 2009 and December 2016 were used to calculate population-specific thresholds of sarcopenia, subcutaneous adiposity, visceral adiposity, visceral obesity, sarcopenic obesity, and myosteatosis. Association between the aforementioned body composition features were related with overall complication, infection, and anastomotic leak. RESULTS During the study period, 311 patients received surgery and 173 were eligible for an accessible preoperative computed tomography imaging. After surgery, 59 (34.1%) patients experienced a complication, 29 an infection, and 10 an anastomotic failure. The overall morbidity rate was observed more frequently in patients with sarcopenia than in those without sarcopenia (39% versus 17.5%; P = 0.002) and infections (41.4% versus 21.5% respectively; P = 0.024). The presence of myosteatosis also was associated with a higher incidence of overall morbidity (33.9% versus 20.2% in patients without myoteatosis; P = 0.048). Anastomotic failure occurred in 6 of 10 patients with visceral obesity and in 24 of 112 (21.4%) patients without this condition (P = 0.007). CONCLUSIONS Some anthropometric indexes are accurate predictors of specific types of morbidity. These findings may allow a more accurate preoperative risk stratification.

Abstract
PURPOSES This study sought to identify any significant predictors of blood loss during pancreatoduodenectomy (PD) among preoperative variables, including the body composition indexes. METHODS The preoperative data of patients undergoing PD were retrospectively reviewed. The objective variable was the percentage of blood loss during PD to the estimated circulating blood volume (proportional blood loss: PBL). The circulating blood volume was estimated using Nadler's formula. The total psoas area, average Hounsfield units of psoas area (psoas muscle density: PMD), and visceral to subcutaneous adipose tissue area ratio (VSR) were measured at the third vertebra using preoperative plain computed tomography images. A univariate analysis and multiple linear regression analysis for PBL were conducted using the preoperative variables. RESULTS A total of 415 patients were analyzed. The median PBL was 24.5%. The PMD (coefficient - 0.267; 95% CI - 0.518, - 0.015), VSR (coefficient 2.719; 95% CI 0.238, 5.201), serum albumin level (coefficient - 8.458; 95% CI - 13.02, - 3.898), neoadjuvant therapy (coefficient 9.605; 95% CI 1.722, 17.49), and prothrombin time-international normalized ratio (PT-INR, coefficient 38.63; 95% CI 10.94, 66.31) were independently associated with PBL. CONCLUSIONS The preoperative PMD, VSR, serum albumin level, neoadjuvant therapy, and PT-INR independently affected PBL. These factors could therefore be potential targets to reduce blood loss during PD.

Abstract
Purpose Progressive loss (sarcopenia) and fatty infiltration of muscle mass (myosteatosis) are well-established risk factors for an adverse clinical outcome in obese patients. Data concerning non-obese sarcopenic patients in oncologic surgery are scarce and heterogeneous. The aim of this study was to determine the impact of sarcopenia and myosteatosis in non-obese patients with cancer of the right colon on clinical outcome. Methods This study comprised 85 patients with a BMI < 30 kg/m2, who underwent surgery for right colon cancer in a single center. Skeletal muscle area (SMA), visceral fat area (VFA), and myosteatosis were retrospectively assessed using preoperative abdominal CT images. Univariate und multivariate analysis was performed to evaluate the association between body composition, complications, and oncologic follow-up. Results Traditional risk factors such as visceral fat (p = 0.8653), BMI (p = 0.8033), myosteatosis (p = 0.7705), and sarcopenia (p = 0.3359) failed to show any impact on postoperative complications or early recurrence. In our cohort, the skeletal muscle index (SMI) was the only significant predictor for early cancer recurrence (p = 0.0467). Conclusion SMI is a significant prognostic factor for early cancer recurrence in non-obese colon cancer patients. Our study shows that conventional thresholds for sarcopenia and BMI do not seem to be reliable across various cohorts. Target prehabilitation programs could be useful to improve outcome after colorectal surgery. Trial Registration DRKS00014655, www.apps.who.int/trialsearch

Abstract
INTRODUCTION Obese patients are considered at increased risk of postoperative adverse events after colorectal surgery. OBJECTIVE The objective of the present study was to compare postoperative outcomes between obese and non-obese patients undergoing elective colorectal surgery in an Enhanced Recovery After Surgery (ERAS) program. METHODS A retrospective analysis of a prospective cohort including patients who underwent elective colorectal surgery and were included in an ERAS protocol between February 2014 and December 2017 at Geneva University Hospital, Geneva, Switzerland, was performed. Postoperative outcomes of obese and non-obese patients were compared. RESULTS Data of 460 patients were analyzed, including 374 (81%) non-obese and 86 (19%) obese patients. Overall, there was no difference in postoperative outcomes between the 2 groups. Among patients undergoing oncologic surgery, obese subjects had a significantly higher rate of conversion to laparotomy (11.9 vs. 2.1%, p = 0.01) and longer time until return of bowel function (2.38 vs. 1.98 days, p = 0.03), without increased morbidity or longer length of stay. CONCLUSION Obese and non-obese patients had similar postoperative outcomes after elective colorectal surgery with ERAS management. ERAS can potentially reduce the increased morbidity usually observed in obese patients following elective colorectal surgery.

Impact of visceral obesity and sarcobesity on surgical outcomes and recovery after laparoscopic resection for colorectal cancer. Clin Nutr 2020; 39:3763-3770. [PMID: 32336524 DOI: 10.1016/j.clnu.2020.04.004] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2020] [Revised: 03/23/2020] [Accepted: 04/04/2020] [Indexed: 12/14/2022]
Abstract
BACKGROUND & AIMS Studies analyzing the impact of visceral fat excess on surgical outcomes after resection for colorectal cancer (CRC) have yielded conflicting results. Visceral obesity (VO) and sarcobesity (SO) have been recently addressed as risk factors for poor short-term results while no data are available for recovery goals after surgery. No data are available on the protective effect of ERAS in VO and SO patients. The aim of this study was to assess clinical implications of computed tomography (CT) assessed VO and SO on surgical and recovery outcomes after minimally invasive resection for CRC before and after ERAS protocol implementation. METHODS Visceral adipose tissue (VAT) and skeletal muscle area (SMA) were retrospectively assessed using pre-operative CT studies of 261 patients who underwent laparoscopic resection for CRC between January 2012 and April 2019; ERAS protocol was adopted in 160 patients operated on after March 2014. Patients' surgical and recovery outcomes were compared according to BMI categories, VO and SO which was defined using the VAT/SMA ratio (Sarcobesity Index). Predictive factors for poor surgical and recovery outcomes were evaluated by univariate and multivariate analyses. RESULTS Of the 261 patients, 12.6% were BMI obese while 68.6% presented visceral obesity. BMI was not associated to any of the outcomes considered. No differences in intra-operative results were found except for a lower number of retrieved lymph nodes both in VO and SO patients. While VO showed no impact on post-operative course, SO resulted an independent risk factor for cardiac complications and prolonged post-operative ileus (PPOI) at logistic regression analysis. Furthermore, sarcobese patients showed delayed recovery after surgery. Patients enrolled in the ERAS protocol showed improved recovery outcomes for both VO and SO groups, although ERAS did not result to be a protective factor for cardiac complications and PPOI. CONCLUSIONS A high Sarcobesity Index is a risk factor for developing cardiac complications and PPOI after laparoscopic resection for CRC. A reduced number of lymph nodes retrieved is associated to VO and SO. These conditions should then be considered in clinical practice for the risk of down staging the N stage. Effect of VO and SO on recovery items after surgery should be further investigated. ERAS protocol application should be implemented to improve recovery outcomes in VO and SO patients undergoing laparoscopic colorectal resection.

Abstract
PURPOSE We aimed to examine the possible relationship between abdominal adiposity parameters and the presence of colorectal cancer (CRC) and between these adiposity parameters and various histopathologic findings of the tumor. METHODS A total of 60 control subjects and 111 CRC patients, 63 with early-stage and 48 with advanced-stage disease, were enrolled. Medical data and abdominopelvic computed tomography (CT) examinations of each study group were retrospectively reviewed. Abdominal adiposity parameters, including visceral adipose tissue (VAT) volume, subcutaneous adipose tissue (SAT) volume, and total adipose tissue (TAT) volume, were calculated on all slices of the CT examinations with specialized software, and results for each study group were compared. Adiposity parameters were also compared with tumor histopathologic findings. RESULTS We found lower VAT and higher SAT volumes in advanced-stage CRC patients, compared with the early-stage group. However, this relationship was not statistically significant (P = 0.721 for VAT and P = 0.432 for SAT volumes). We detected significantly lower VAT and SAT volumes in the early-stage CRC group compared with the control group (P = 0.014 for both). There was no significant relationship between TAT volumes and the study groups (P = 0.06). No statistically significant relationship was detected between adipose tissue parameters and histopathologic features of the CRC group (P > 0.05). CONCLUSION We found statistically significant lower VAT and SAT volumes in patients with early-stage CRC compared with the control group. Volumetric adipose tissue measurements may be more accurate than area measurements and can easily be performed on abdominopelvic CT examination, which is the routine imaging modality for CRC patients.

Abstract
GOALS The aim of this study was to determine a potential strategy to prevent acute pancreatitis (AP) from deteriorating in obese patients. BACKGROUND Nutritional support plays a critical role in the treatment of AP. Early enteral nutrition (EEN) is considered to be able to protect mucosa of AP patients and alleviate inflammatory reactions. Obesity worsen AP prognosis. However, little is known about the effects of EEN in obese patients. STUDY Prospective randomized control trial. Subjects with moderately severe AP or severe AP were divided into the visceral fat obesity (VFO) group and the non-VFO group by obesity index VFO. The patients received "delayed" enteral nutrition (started enteral nutrition feeding after the first 48 hours after admission to the hospital: group A: patients of non-VFO, n=108; group B: VFO patients, n=88) or EEN (in the VFO subgroup, group C: n=91).Occurrence of complication, clinical outcomes, plasma levels of cytokines, and intestine gut barrier index were measured at different timepoints after admission. RESULTS VFO was a risk factor for aggravating of AP. EEN prevented the VFO patients from developing pancreatic necrotic infection, the mechanism of which might be related with inhibiting excessive inflammatory reactions, adjusting the imbalance of inflammatory response, and alleviating ischemia of intestine mucosa. CONCLUSIONS The potential strategy, EEN, was able to prevent AP from deteriorating in obese patients.

Abstract
Abdominal visceral fat is a well-recognized a risk for colorectal cancer (CRC). In contrast to the risk for CRC, the impact of adiposity in disease staging and patient survival is less well-established. Our aim was to critically review the literature on the influence of adiposity assessed by different methods routinely used in clinical settings, on CRC staging and prognosis. In the 32 studies reviewed, overweight was initially identified as a survival advantage, an evidence that was later challenged by studies suggesting that body adiposity is likely to have a deleterious effect in CRC outcomes, particularly in males. Hence, whether obesity has a negative impact in CRC staging or prognosis remains controversial. In sum, addressing the impact of body fat in CRC biological behavior is still an unmet need. Understanding how adiposity influences CRC staging and prognosis could allow further patient risk stratification for devising targeted interventions and improve clinical outcomes.

The Incidence of Postoperative Complications after Gastrectomy Increases in Proportion to the Amount of Preoperative Visceral Fat. JOURNAL OF ONCOLOGY 2019; 2019:8404383. [PMID: 31929799 PMCID: PMC6942899 DOI: 10.1155/2019/8404383] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/23/2019] [Revised: 10/23/2019] [Accepted: 10/30/2019] [Indexed: 12/12/2022]
Abstract
Background Visceral obesity is a risk factor for complications after gastrectomy in patients with gastric cancer. However, it is unclear whether postoperative complications decrease with preoperative reduction of visceral fat without the achievement of a nonobese state. This is because previous studies have performed categorical comparisons of obesity and nonobesity. The current study was performed to estimate the impact of the preoperative visceral fat area (VFA) as a continuous variable on postoperative complications after gastrectomy. Methods Consecutive patients with gastric cancer who underwent curative gastrectomy between June 2006 and August 2017 at the Kyoto University Hospital were included in this retrospective study. The VFA at the level of the umbilicus was measured using preoperative computed tomography. The relationship between postoperative complications and VFA was investigated with univariate and multivariate analyses. Results total of 566 patients were included in the study. Their mean VFA was 110 ± 58 cm2, and postoperative complications occurred in 121 patients (21.4%). The larger the VFA (<50, 50–99, 100–149, and ≥150 cm2), the higher the incidence of postoperative complications (11%, 14%, 21%, and 38%, respectively, P < 0.001). Multivariate logistic regression analyses showed that the VFA was associated with postoperative complications (odds ratio: 1.009, 95% confidence interval (CI): 1.004–1.013, P < 0.001), with an incidence of postoperative complications that was 9% (95% CI: 4%–12%) higher for every 10 cm2 increase in the VFA. Conclusion The incidence of postoperative complications after gastrectomy increases in proportion to an increase in the preoperative VFA.

Abstract
Background Current literature is inconsistent in the associations between computed tomography (CT)‐based body composition measures and adverse outcomes in older patients with colorectal cancer (CRC). Moreover, the associations with consecutive treatment modalities have not been studied. This study compared the associations of CT‐based body composition measures with surgery‐ and chemotherapy‐related complications and survival in older patients with CRC. Materials and Methods A retrospective single‐center cohort study was conducted in patients with CRC aged ≥65 years who underwent elective surgery between 2010 and 2014. Gender‐specific standardized scores of preoperative CT‐based skeletal muscle (SM), muscle density, intermuscular adipose tissue (IMAT), visceral adipose tissue (VAT), subcutaneous adipose tissue, IMAT percentage, SM/VAT, and body mass index (BMI) were tested for their associations with severe postoperative complications, prolonged length of stay (LOS), readmission, and dose‐limiting toxicity using logistic regression and 1‐year and long‐term survival (range 3.7–6.6 years) using Cox regression. Bonferroni correction was applied to account for multiple testing. Results The study population consisted of 378 patients with CRC with a median age of 73.4 (interquartile range 69.5–78.4) years. Severe postoperative complications occurred in 13.0%, and 39.4% of patients died during follow‐up. Dose‐limiting toxicity occurred in 77.4% of patients receiving chemotherapy (n = 53). SM, muscle density, VAT, SM/VAT, and BMI were associated with surgery‐related complications, and muscle density, IMAT, IMAT percentage, and SM/VAT were associated with long‐term survival. After Bonferroni correction, no CT‐based body composition measure was significantly associated with adverse outcomes. Higher BMI was associated with prolonged LOS. Conclusion The associations between CT‐based body composition measures and adverse outcomes of consecutive treatment modalities in older patients with CRC were not consistent or statistically significant. Implications for Practice Computed tomography (CT)‐based body composition, including muscle mass, muscle density, and intermuscular, visceral, and subcutaneous adipose tissue, showed inconsistent and nonsignificant associations with surgery‐related complications, dose‐limiting toxicity, and overall survival in older adults with colorectal cancer. This study underscores the need to verify whether CT‐based body composition measures are worth implementing in clinical practice. Colorectal cancer is prevalent in older individuals. This article compares the associations of computed tomography‐based body composition measures with surgery‐ and chemotherapy‐related complications and survival in older patients with colorectal cancer.

Abstract
BACKGROUND The predictive risk factors of clinically relevant pancreatic fistula (CR-PF) following distal pancreatectomy (DP) remain to be identified. METHODS This is a retrospective cohort analysis of a single-institution database of patients undergoing DP, taking into account usual demographic, operative, and pathologic variables and visceral fat area (VFA), total muscle area (TMA), and surface muscle index (SMI) measured on preoperative CT scan. The primary end point was CR-PF. All variables associated with a p value < 0.05 on univariate analysis were included in a logistic regression model for multivariate analysis. RESULTS From 2012 to 2016, 208 patients operated by 4 pancreatic surgeons underwent DP including 32 (15%) who developed CR-PF. Risk factors of CR-PF on univariate analysis were: BMI ≥ 25 kg/m2 (p = 0.050), VFA ≥ 92 cm2 (p = 0.006), laparotomy (p = 0.023), main pancreatic duct dilatation (p = 0.035), open passive drainage (versus closed suction drainage) (p = 0.001), and blood loss ≥ 225 ml (p = 0.001). Sarcopenia did not influence the risk of CR-PF (p = 0.076). On multivariate analysis, VFA ≥ 92 cm2 (OR 3.14; IC 95% (1.18-8.31), p = 0.022), blood loss ≥ 225 ml (OR: 2.72; IC 95% (1.06-6.96), p = 0.037), and open passive drainage (OR 3.72; IC 95% (1.40-9.87) p = 0.008) were three independent predictive factors of CR-PF. A CR-PF risk score was developed, predicting a 0% risk of CR-PF when no risk factors were present and a 39% risk when the 3 risk factors were present. CONCLUSIONS Visceral obesity, blood loss ≥ 225 ml and open passive drainage significantly increase the risk of CR-PF following DP.

Abstract
OBJECTIVE To assess the impact of visceral obesity quantified by preoperative computed tomography on short-term postoperative outcomes compared with body mass index (BMI) in stage I-III colon adenocarcinoma patients. METHODS In this retrospective study, 107 patients treated with radical colectomy for stage I-III colon adenocarcinoma were classified as obese or non-obese by computed tomography-based measures or BMI (obese: BMI ≥28 kg/m2 , visceral fat area (VFA) to subcutaneous fat area ratio (V/S) ≥0.4, and VFA ≥100 cm2 ). Clinical variables, operation time, estimated blood loss, pathologic stage, histologic grade, postoperative complications, postoperative stay and hospitalization expenses were compared. RESULTS Obese patients by VFA were more likely to have higher postoperative complication rate (32.9 versus 11.8%, P = 0.021), have longer operation time (184.6 ± 49.5 versus 163.1 ± 44.1 min, P = 0.033), postoperative stay (15.21 ± 7.59 versus 12.29 ± 5.40 days, P = 0.047) and cost more ($10 758.7 ± 3271.7 versus $9232.0 ± 2994.6, P = 0.023) than non-obese. CONCLUSION Visceral obesity graded by VFA is associated with increased postoperative morbidity, operation time, postoperative stay and hospitalization expenses for colon adenocarcinoma patients and may be superior to BMI or V/S for the prediction of colon surgery.

Visceral obesity and short-term outcomes after laparoscopic rectal cancer resection. Surg Endosc 2019; 34:177-185. [PMID: 30887182 DOI: 10.1007/s00464-019-06748-4] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2018] [Accepted: 03/06/2019] [Indexed: 12/13/2022]
Abstract
BACKGROUND Complications after rectal resection are frequent. Recently, methods to assess visceral obesity (VO) have become available as an alternative to measurement of body mass index (BMI). The aim of this study was to examine the association between visceral fat volume (VFV) and the short-term outcomes after laparoscopic low anterior resection (LLAR) in patients with rectal cancer. METHODS We studied a consecutive series of patients undergoing LLAR at Bispebjerg University Hospital from 01.01.2013 to 01.01.2016. Preoperative VFV was calculated from abdominal CT scans using an automatic segmentation tool. The primary outcome was anastomotic leakage (AL). Secondary outcomes included conversion to open surgery, number of lymph nodes harvested, the rates of 30-day complications as well as reoperations, and 1-year survival. RESULTS A total of 102 patients were included. VO was defined as a VFV above the 75 percentile. Thirteen (12.7%) patients developed AL, four (15.4%) of whom were in the VO group (p = 0.900). At least one postoperative complication developed in 38 (37.3%) patients, with no significant difference between the VO and non-VO patients after univariable analysis (42.3% vs. 35.4%, p = 0.702) or multivariable adjustment (OR 1.01, 95% CI 0.38-2.65, p = 0.984). VO was significantly associated with an increased incidence of conversion to open surgery (OR 4.30, 95% CI 1.29-14.86, p = 0.018). There was a significant difference in the number of harvested lymph nodes between the two groups (mean 23.5 vs. 29.1, p = 0.045). CONCLUSIONS In this study on patients undergoing laparoscopic rectal resection, VO was not associated with development of AL or other complications. However, we found that visceral obesity was associated with an increased risk of conversion to open surgery.

Abstract
BACKGROUND Analytic morphomics, or more simply, "morphomics," refers to the measurement of specific biomarkers of body composition from medical imaging, most commonly computed tomography (CT) images. An emerging body of literature supports the use of morphomic markers measured on single-slice CT images for risk prediction in a range of clinical populations. However, uptake by healthcare providers been limited due to the lack of clinician-friendly software to facilitate measurements. The objectives of this study were to describe the interface and functionality of CoreSlicer- a free and open-source web-based interface aiming to facilitate measurement of analytic morphomics by clinicians - and to validate muscle and fat measurements performed in CoreSlicer against reference software. RESULTS Measurements of muscle and fat obtained in CoreSlicer show high agreement with established reference software. CoreSlicer features a full set of DICOM viewing tools and extensible plugin interface to facilitate rapid prototyping and validation of new morphomic markers by researchers. We present published studies illustrating the use of CoreSlicer by clinicians with no prior knowledge of medical image segmentation techniques and no formal training in radiology, where CoreSlicer was successfully used to predict operative risk in three distinct populations of cardiovascular patients. CONCLUSIONS CoreSlicer enables extraction of morphomic markers from CT images by non-technically skilled clinicians. Measurements were reproducible and accurate in relation to reference software.

Abstract
AIM Enhanced recovery after surgery (ERAS) programmes aim to standardise perioperative care leading to optimal patient outcomes. Despite these programmes, variation in outcomes still persists. This study aimed to assess the influence of lifestyle factors on short-term outcomes after colorectal surgery within this optimal recovery programme. METHODS Consecutive patients enrolled on an ERAS pathway who underwent elective colorectal surgery (June 2013 to July 2014) at one site were included. We used data routinely collected by ERAS nurse specialists and during preassessment to analyse association between patient and lifestyle factors and likelihood of developing postoperative complications or having an increased length of stay. RESULTS A total of 199 patients were included: mean age 61.8 years (range 17-90 years) and 53.8% male. Age, sex, deprivation, smoking status, alcohol intake, body mass index or level of comorbidity were not associated with postoperative complications. Patients reporting limited preoperative physical capacity (unable to climb two flights of stairs) were more than four times as likely to have a postoperative complication on univariate analysis and were found to still have increased risk of postoperative complications on multivariate analysis. Patients reporting limited preoperative physical capacity were shown to have significantly longer hospital stay on univariate analysis. In the multivariate analysis, limited physical capacity was not associated with prolonged length of stay due to confounding factors of age and deprivation. CONCLUSIONS Limited physical capacity was the only patient and lifestyle factor associated with poorer postoperative complications and prolonged hospital stay after elective colorectal surgery within an ERAS programme. Consideration should be given to individualised prehabilitation that aims to increase physical capacity pre-operatively to improve patient outcomes.

Abstract
ObjectivesTo determine if linear measurements of adiposity from pre-operative imaging can improve anticipation of surgical difficulty among endometrial cancer patients.MethodsEighty patients with newly diagnosed endometrial cancer were enrolled. Routine pre-operative imaging (MRI or CT) was performed. Radiologic linear measurements of the following were obtained: anterior-to-posterior skin distance; anterior skin to anterior edge of L5 distance (total anterior); anterior peritoneum to anterior edge of L5 distance (visceral obesity); and posterior edge of L5 to posterior skin distance (total posterior). Surgeons completed questionnaires quantifying preoperative anticipated operative difficulty and postoperative reported operative difficulty. The primary objective was to assess for a correlation between linear measurements of visceral fat and reported operative difficulty.ResultsSeventy-nine patients had questionnaires completed, preoperative imaging obtained, and surgery performed. Univariate analysis showed all four linear measurements, body mass index, weight, and anticipated operative difficulty were associated with increased reported operative difficulty (P< 0.05). Multivariate analysis demonstrated that body mass index and linear measurements visceral obesity and total posterior were independently associated with increased reported operative difficulty (P< 0.05). Compared with body mass index, the visceral obesity measurement was more sensitive and specific for predicting increased reported operative difficulty (visceral obesity; sensitivity 54%, specificity 91 %; body mass index; sensitivity 38%, specificity 89%). A difficulty risk model combining body mass index, visceral obesity, and total posterior demonstrated better predictive performance than any individual preoperative variable.ConclusionsSimple linear measurements of visceral fat obtained from preoperative imaging are more predictive than body mass index alone in anticipating surgeon-reported operative difficulty. These easily obtained measurements may assist in preoperative decision making in this challenging patient population.

Abstract
AIM Visceral obesity is associated with perioperative and postoperative complications in colorectal surgery. We aimed to investigate the association between the perirenal fat surface area (PRF) and postoperative complications. METHOD Data on 610 patients undergoing curative, elective colon cancer resection between 2006 and 2016 at Stockholm South General Hospital were retrieved from a local quality register. We assessed perioperative and postoperative outcomes using a multinomial regression model adjusted for age, sex, American Society of Anesthesiologists classification and surgical approach (open/laparoscopy) in relation to PRF. RESULTS PRF could be measured in 605 patients; the median area was 24 cm2 . Patients with PRF ≥ 40 cm2 had longer operation time (median 223 vs 184 min), more intra-operative bleeding (250 vs 125 ml), reoperations (11% vs 6%), surgical complications (27% vs 13%) and nonsurgical infectious complications (16% vs 9%) than patients with PRF < 40 cm2 , but there were no differences in the need for intensive care or duration of hospital stay. The multivariate analyses revealed an increased risk of any complication [OR 1.68 (95% CI 1.1-2.6)], which was even more pronounced for moderate complications [Clavien-Dindo II, OR 2.14 (CI 1.2-2.4]; Clavien-Dindo III, OR 2.35 (CI 1.0-5.5)] in patients with PRF ≥ 40 vs < 40 cm2 . The absolute risk of complications was similar in men and women with PRF ≥ 40 cm2 . CONCLUSION PRF, an easily measured indirect marker of visceral obesity, was associated with overall and moderate complications in men and women and could serve as a useful tool in the assessment of preoperative risk.

Abstract
Background We investigated whether visceral adiposity is associated with more aggressive disease at prostatectomy. Materials and methods Four hundred and seventy-four patients referred for postoperative adjuvant or salvage radiotherapy were included in this study. Primary endpoints were positive surgical margins (pSM) or extracapsular extension (ECE). Visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) were manually contoured. Univariate and multivariate logistic regression was performed. Results In univariate analysis, VAT volume (p = 0.006), adipose tissue ratio (VAT/SAT, p = 0.003), density of the SAT (p = 0.04), as well as age (p < 0.001) were associated with pSM. In the univariate analysis, SAT density was associated with a trend towards a higher rate of ECE (p = 0.051) but visceral fat volume (p = 0.01), as well as the adipose tissue ratio (p = 0.03) were both protective factors. None of the adipose tissue measurements or BMI had an influence on biochemical recurrence or overall survival (all p ≥ 0.5). Conclusions SAT-volume and increased SAT-density were generally associated with more aggressive prostate cancers whereas VAT as a protective factor. These findings emphasize a possible mechanism for the association between obesity and prostate cancer aggressiveness.

Abstract
BACKGROUND/OBJECTIVES Currently, there are no widely accepted cut-off points to categorize patients as sarcopenic (low skeletal muscle mass) or myosteatotic based on computed tomography (CT) measurements. Moreover, little is known about skeletal muscle mass in healthy subjects, particularly in a Western-European population. SUBJECTS/METHODS Skeletal muscle mass (skeletal muscle index, cm2/m2) and density (Hounsfield units, HU) at the level of the third lumbar vertebra were measured on contrast-enhanced CT images in live kidney donors with an age range of 18-86 years, who may be considered as healthy subjects, from 2010 to 2015. Differences between sex, body mass index (BMI), age groups, and American Society of Anesthesiologists (ASA) classification were assessed. Mann-Whitney U and Kruskal-Wallis tests were used to compare groups. RESULTS Of the 1073 included patients, 499 (46.5%) were male and the median age and BMI were 51 years and 25.4 kg/m2, respectively. Male gender, increased age, and increased BMI were significantly associated with both skeletal muscle mass and density. Nomograms including these parameters were developed to calculate the estimated skeletal muscle mass and density of a healthy subject and the lower bound of the 90% prediction interval (p5) values were provided. CONCLUSIONS Skeletal muscle density and mass were significantly associated with sex, age, and BMI in a large cohort of healthy Western-European subjects. The newly developed nomograms may be used to calculate the estimated healthy skeletal muscle mass for individuals in patient populations.

Abstract
BACKGROUND Sarcopenia, visceral obesity (VO), and reduced muscle radiodensity (myosteatosis) are suggested risk factors for postoperative morbidity in colorectal cancer (CRC), but usually are not concurrently assessed. Published thresholds used to define these features are not CRC-specific and are defined in relation to mortality, not postoperative outcomes. This study aimed to evaluate body composition in relation to length of hospital stay (LOS) and postoperative outcomes. METHODS Pre-surgical computed tomography (CT) images were assessed for total area and radiodensity of skeletal muscle and visceral adipose tissue in a pooled Canadian and UK cohort (n = 2100). Sex- and age-specific values for these features were calculated. For 1139 of 2100 patients, LOS data were available, and sex- and age-specific thresholds for sarcopenia, myosteatosis, and VO were defined on the basis of LOS. Association of CT-defined features with LOS and readmissions was explored using negative binomial and logistic regression models, respectively. RESULTS In the multivariable analysis, the predictors of LOS (P < 0.001) were age, surgical approach, major complications (incidence rate ratio [IRR] 2.42; 95% confidence interval [CI] 2.18-2.68), study cohort, and three body composition profiles characterized by myosteatosis combined with either sarcopenia (IRR, 1.27; 95% CI 1.12-1.43) or VO (IRR, 1.25; 95% CI 1.10-1.42), and myosteatosis combined with both sarcopenia and VO (IRR, 1.58; 95% CI 1.29-1.93). In the multivariable analysis, risk of readmission was associated with VO alone (odds ratio [OR] 2.66; 95% CI 1.18-6.00); P = 0.018), VO combined with myosteatosis (OR, 2.72; 95% CI 1.36-5.46; P = 0.005), or VO combined with myosteatosis and sarcopenia (OR, 2.98; 95% CI 1.06-5.46; P = 0.038). Importantly, the effect of body composition profiles on LOS and readmission was independent of major complications. CONCLUSION The findings showed that CT-defined multidimensional body habitus is independently associated with LOS and hospital readmission.

Abstract
BACKGROUND With the increased prevalence of obesity and sarcopenia, those patients with both visceral obesity and sarcopenia were at higher risk of adverse outcomes. AIM The aim of this study was to ascertain the combined impact of visceral obesity and sarcopenia on short-term outcomes in patients undergoing colorectal cancer surgery. METHODS We conducted a prospective study from July 2014 to February 2017. Patients' demographic, clinical characteristics, physical performance, and postoperative short-term outcomes were collected. Patients were classified into four groups according to the presence of sarcopenia or visceral obesity. Clinical variables were compared. Univariate and multivariate analyses evaluating the risk factors for postoperative complications were performed. RESULTS A total of 376 patients were included; 50.8 and 24.5% of the patients were identified as having "visceral obesity" and "sarcopenia," respectively. Patients with sarcopenia and visceral obesity had the highest incidence of total, surgical, and medical complications. Patients with sarcopenia or/and visceral obesity all had longer hospital stays and higher hospitalization costs. Age ≥ 65 years, visceral obesity, and sarcopenia were independent risk factors for total complications. Rectal cancer and visceral obesity were independent risk factors for surgical complications. Age ≥ 65 years and sarcopenia were independent risk factors for medical complications. Laparoscopy-assisted operation was a protective factor for total and medical complications. CONCLUSION Patients with both visceral obesity and sarcopenia had a higher complication rate after colorectal cancer surgery. Age ≥ 65 years, visceral obesity, and sarcopenia were independent risk factors for total complications. Laparoscopy-assisted operation was a protective factor.

Abstract
AIM To determine the relationship of visceral fat (VF) with the surgical outcome of the patients with colorectal cancer (CRC) submitted to curative surgery. METHODS Retrospective analysis of all patients submitted to CRC surgery during 3 years with a minimum of 5 years of follow-up. We assessed the length of hospital stay, complications, pathologic reports, surgical re-interventions and hospital re-admissions, relapses, survival time and disease-free time. VF was calculated based on patients' pre-operative CT-scan. The patients were divided into quartiles according to the VF area. Linear regression models and logistic regression models were used to establish a relationship between VF and all data collected. RESULTS The study included 199 patients (129 with colon cancer [CC] and 70 with rectal cancer). The average area of VF was 115.7 cm2. Patients with CRC revealed a direct relationship between VF and postoperative complications (p = 0.043), anastomotic leakage (p = 0.009) and re-operation (p = 0.005). The subgroup of patients with CC had an inverse association between VF and lymph nodes harvested (p = 0.027). Survival analyses did not reveal significant differences. CONCLUSION VF has an influence on postoperative complications, anastomotic leakage and re-operation. A negative influence of VF on lymph nodes harvested was observed on CC patients.

Abstract
BACKGROUND The association of sarcopenia and visceral obesity to treatment outcome is not clear for locally advanced rectal cancer. This study evaluates the influence of skeletal muscle and visceral fat on short-term and long-term outcomes in locally advanced rectal cancer patients treated with neoadjuvant chemoradiation therapy followed by curative resection. METHODS A total of 188 patients with locally advanced cancer were included between January 2009 and December 2013. Neoadjuvant chemoradiotherapy was followed by curative resection. Sarcopenia and visceral obesity were identified in initial staging CT by measuring the muscle and visceral fat area at the third lumbar vertebra level. RESULTS Among the 188 included patients, 74 (39.4%) patients were sarcopenic and 97 (51.6%) patients were viscerally obese. Sarcopenia and high levels of preoperative carcinoembryonic antigen were significant prognostic factors for overall survival (P = 0.013, 0.014, respectively) in the Cox regression multivariate analysis. Visceral obesity was not associated with overall survival; however, it did tend to shorten disease-free survival (P = 0.079). CONCLUSIONS Sarcopenia is negatively associated with overall survival in locally advanced rectal cancer patients who underwent neoadjuvant chemoradiation therapy and curative resection. Visceral obesity tended to shorten disease-free survival. Future studies should be directed to optimize patient conditions according to body composition status.
