Sarcopenia discriminates poor prognosis in elderly patients following emergency surgery for perforation panperitonitis.

ABSTRACT:

Aim

Sarcopenia has been reported as a prognostic predictor in various conditions; however, it has not been examined in patients with perforation panperitonitis.

Methods

A total of 103 consecutive patients with perforation panperitonitis who underwent emergency surgery from 2008 to 2016 were retrospectively evaluated. Skeletal muscle index (SMI) was measured as the cross-sectional area (cm²) of skeletal muscle in the L3 region on computed tomography images normalized for height (cm²/m²). Sarcopenia was defined as an SMI of ≤43.75 and ≤41.10 cm²/m² in men and women, respectively. The impact of sarcopenia on postoperative outcomes was investigated.

Results

Sarcopenia was present in 50 (48.5%) patients. Severe complications (Clavien-Dindo grade ≥IIIb) and in-hospital mortality were more frequently observed in patients with than without sarcopenia (28.0% vs 9.4%, P = .015) (20.0% vs 5.7%, P = .029) respectively. Multivariate analysis showed that age, sarcopenia, and renal dysfunction were independent risk factors for severe complications and in-hospital mortality. The optimal cut-off levels of age and SMI for predicting these were ≥79 years and SMI <38 cm²/m², respectively. Among the patients aged ≥79 years, those with SMI <38 cm²/m² had a severe complication rate of 71% and an in-hospital mortality rate of 57%, whereas the rate of those with SMI ≥38 cm²/m² was 22% (P = .011) and 11% (P = .008), respectively.

Conclusion

Sarcopenia is a predictive factor of severe complications and in-hospital mortality following emergency surgery for perforation panperitonitis, especially in elderly patients. Estimation of sarcopenia may identify patients eligible or not eligible for emergency surgery among elderly patients.

Project description:Abstract Aim Frailty assessment in elderly patients is crucial to predict the postoperative course, considering that frailty is highly associated with postoperative complications and mortality. The aim of this study was to evaluate the value of osteopenia as a risk factor for severe postoperative complications in elderly patients who underwent emergency gastrointestinal surgery. Methods This study comprised 103 elderly patients who underwent emergency gastrointestinal surgery. Osteopenia was diagnosed by measuring bone mineral density, which was calculated as the average pixel density in the midvertebral core at the 11th thoracic vertebra on the preoperative plain computed tomography image. We retrospectively investigated the relationship between preoperative osteopenia and severe postoperative complications (Clavien–Dindo classification ≥III). Univariate and multivariate analyses were performed to evaluate the risk factors for severe postoperative complications. Results Twenty‐three patients (22.3%) developed severe postoperative complications. The optimal cutoff value of bone mineral density for severe postoperative complications was 119.5 Hounsfield unit (HU) and 39 patients (37.9%) were diagnosed with osteopenia. The univariate analysis revealed that the American Society of Anesthesiologists Physical Status of ≥3 (P = .0084), hemoglobin levels (P = .0026), albumin levels (P < .001), sarcopenia (P = .015), and osteopenia (P < .001) were significantly associated with severe postoperative complications. The multivariate analysis showed that osteopenia (P = .014) was an independent risk factor for severe postoperative complications. Conclusion Osteopenia may be a risk factor for severe postoperative complications in elderly patients after emergency gastrointestinal surgery. The aim of this study is to evaluate the value of osteopenia for severe postoperative complications in elderly patients who underwent emergency gastrointestinal surgery. In the multivariate analysis, osteopenia was an independent risk factor for severe postoperative complications. Osteopenia may be a risk factor for severe postoperative complications in elderly patients after emergency gastrointestinal surgery.

Project description:BackgroundReports indicate that black patients have lower survival after the diagnosis of a poor prognosis cancer, compared with white patients. We explored the extent to which this disparity is attributable to the underuse of surgery.Study designUsing the Surveillance, Epidemiology, and End Results program and Medicare database, we identified 57,364 patients, ages 65 years and older, with a new diagnosis of nonmetastatic liver, lung, pancreatic, and esophageal cancer, from 2000 to 2005. We evaluated racial differences in resection rates after adjustment for patient, tumor, and hospital characteristics using hierarchical logistic regression. Cox proportional hazards regression was used to assess racial differences in survival after adjusting for patient, tumor, and hospital characteristics, and receipt of surgery.ResultsCompared with white patients, black patients were less likely to undergo surgery for liver (adjusted odds ratio [aOR] = 0.49; 95% CI, 0.29-0.83), lung (aOR = 0.62; 95% CI, 0.56-0.69), pancreas (aOR = 0.53; 95% CI, 0.41-0.70), and esophagus cancers (aOR = 0.64; 95% CI, 0.42-0.99). Hospitals varied in their surgery rates among patients with potentially resectable disease. However, resection rates were consistently lower for black patients, regardless of the resection rate of the treating hospital. Although there were no racial differences in overall survival with liver and esophageal cancer, black patients experienced poorer survival for lung (adjusted hazard ratio = 1.05; 95% CI, 1.00-1.10) and pancreas cancer (adjusted hazard ratio = 1.15; 95% CI, 1.03-1.30). In both instances, there were no residual racial disparities in overall survival after adjusting for use of surgery.ConclusionsBlack patients are less likely to undergo surgery after diagnosis of a poor prognosis cancer. Our findings suggest that surgery is an important predictor of overall mortality, and that efforts to reduce racial disparities will require stakeholders to gain a better understanding of why elderly black patients are less likely to get to the operating room.
