Background: Sarcopenia is a surrogate marker for malnutrition and frailty, which has been linked to higher complication rates and prolonged length of stay (LOS) after surgery. The study aim was to assess the correlation between computed tomography (CT)‐based sarcopenia and short‐term clinical outcomes after oncologic colon surgery. Methods: This retrospective study included consecutive patients operated between May 2014 and December 2019. Three radiological indices of sarcopenia were measured at the level of the third lumbar vertebra on preoperative CT scans: skeletal muscle area (SMA), skeletal muscle index (SMI) (both markers of muscle quantity), and skeletal muscle radiation attenuation (SMRA) (marker of muscle quality). Patients with major complications (grade ≥ 3b according to the Clavien classification) were compared with those without. Statistical correlation between sarcopenia indices, LOS, and comprehensive complication index (CCI) was tested with the Pearson correlation coefficient. Results: A total of 325 patients were included. Mean age was 67 years [standard deviation (SD) 14.3], mean body mass index was 26.0 kg/m2 (SD 5.3), and 193 (59%) were male. Fifty patients (15.4%) had major complications, while 275 (84.6%) did not. Patients with major complications had more open surgery (52 vs. 21%, P < 0.01), intraoperative blood loss (257 vs. 102 mL, P = 0.035), and intraoperative complications (22 vs. 9%, P = 0.012). Patients with major complications had significantly increased CCI scores (53 vs. 6, P < 0.01), reoperations (74 vs. 0%, P < 0.01), and LOS (33 vs. 7, P < 0.01). SMA and SMI were comparable between both groups (126.0 vs. 125.2 cm2, P = 0.974, and 43.4 vs. 44.3 cm2/m2, P = 0.636, respectively), while SMRA was significantly lower in patients with major complications (33.6 vs. 37.3 HU, P = 0.018). A lower SMRA was correlated with prolonged LOS (r = −0.207, P < 0.01) and higher CCI (r = −0.144, P < 0.01), while the other sarcopenia indices had no influence on surgical outcomes. Conclusions: Muscle quality (SMRA) as a specific sarcopenia marker was lower in patients with major complications and seems to prevail over muscle quantity (SMA and SMI) in the prediction of adverse outcomes after oncologic colon surgery.

Rationale: The aim of this study was to identify temporal readmission patterns according to baseline disease categories to provide opportunities for targeted interventions. Methods: Retrospective analysis of consecutive adult (≥18 years) patients who underwent elective colorectal resections (2011‐2017) at Mayo Clinic Rochester, MN. A prospective administrative database including patient demographics, procedure characteristics, discharge information and specifics on 30‐day readmissions (to index facility) including timing and reasons was utilized. The ICD‐9 codes were regrouped into the main pathologies Cancer, Crohn's disease (CD)/chronic ulcerative colitis (CUC), and diverticular disease. Results: In total, 521 (7.2%) out of 7245 patients undergoing inpatient colorectal surgery were readmitted. In all increments of time from discharge (0‐2 days: 31.3% of all readmissions, 3‐7 days: 32.4% of all readmissions, 8‐14 days: 18% of all readmissions, and 15‐30 days: 18.3% of all readmissions), reasons for readmission differed significantly (all P < 0.001). Across all disease categories, early readmissions (within 2 days of discharge) were most likely due to ileus/obstruction (53.4% of early readmissions), whereas with 42.5%, infection was the most common cause for late readmissions (>7 days). Patients with home discharge were more likely to be readmitted earlier within the 30‐day observation period (P = 0.099), whereas patients with a longer length of index hospital stay (>7 days) were readmitted later (P = 0.080). Conclusions: Reasons for readmission appear to be universal across different disease categories. Targeted educational and collaborative measures may help to mitigate the burden of hospital readmissions to index facilities. [ABSTRACT FROM AUTHOR]

Rationale: The present study aimed to define thresholds for perioperative fluids and weight gain after urgent colectomies. Method: Consecutive urgent colonic resections within an enhanced recovery pathway (2011‐2017) were included. Primary outcomes were postoperative complications, stratified as overall (I‐V) and major (IIIb‐V) according to Clavien scale. Fluid‐management–related thresholds were identified through receiver operating characteristics (ROC) analysis. Outcomes were compared for patients above vs below threshold, and multivariable logistic regression was performed to identify risk factors for overall complications. Results: Overall, complications were observed in 133 out of 224 patients (59%), severe complications in 43 patients (19%). For overall complications, area under ROC (AUROC) was 0.71, identifying a critical cut‐off of 3 L of total IV fluid administration at the day of surgery (negative predictive value [NPV]: 90%). Further, a critical cut‐off for postoperative weight gain of 2.3 kg at postoperative day (POD) 2 was identified (AUROC 0.7, NPV 92%). Multivariable analysis identified fluid administration of >3 L (OR 5.33; 95% CI, 2.36‐12.02) and weight gain of >2.3 kg at POD 2 (OR 2.5; 95% CI, 1.13‐5.53) as independent predictors for overall complications. Median length of stay was 7 (5‐10) days in patients receiving <3 L at POD 0 and 13 (9‐19) days in patients receiving >3 L (P <.001). Conclusions: Fluid administration of 3 L at the day of surgery and weight gain of 2.3 kg at POD 2 may represent critical thresholds for adverse outcomes after urgent colectomy. The suggested thresholds need to be confirmed through independent validation. [ABSTRACT FROM AUTHOR]
