Effect of sarcopenia in predicting postoperative mortality in emergency laparotomy: a systematic review and meta-analysis

Abstract

Background While emergency laparotomy has been associated with high rates of postoperative mortality and adverse events, preoperative systematic evaluation of patients may improve perioperative outcomes. However, due to the critical condition of the patient and the limited operation time, it is challenging to conduct a comprehensive evaluation. In recent years, sarcopenia is considered a health problem associated with an increased incidence of poor prognosis. This study aimed to investigate the effect of sarcopenia on 30-day mortality and postoperative adverse events in patients undergoing emergency laparotomy. Methods We systematically searched databases including PubMed, Embase, and Cochrane for all studies comparing emergency laparotomy in patients with and without sarcopenia up to March 1, 2022. The primary outcome was of 30-day postoperative mortality. Secondary outcomes were the length of hospital stay, the incidence of adverse events, number of postoperative intensive care unit (ICU) admissions, and ICU length of stay. Study and outcome-specific risk of bias were assessed using the Quality in Prognosis Studies (QUIPS) tool. We rated the certainty of evidence using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE). Result A total of 11 eligible studies were included in this study. The results showed that patients with sarcopenia had a higher risk of death 30 days after surgery (OR = 2.42, 95% CI = 1.93–3.05, P < 0.00001). More patients were admitted to ICU after surgery (OR = 1.58, 95% CI = 1.11–2.25, P = 0.01). Both the ICU length of stay (MD = 0.55, 95% CI = 0.05–1.06, P = 0.03) and hospital length of stay (MD = 2.33, 95% CI = 1.33–3.32, P < 0.00001) were longer in the sarcopenia group. The incidence of postoperative complications was also significantly higher in patients with sarcopenia (OR = 1.78, 95% CI = 1.41–2.26, P < 0.00001). Conclusion In emergency laparotomy, sarcopenia was associated with increased 30-day postoperative mortality. Both the lengths of stay in the ICU and the total length of hospital stay were significantly higher than those in non-sarcopenic patients. Therefore, we concluded that sarcopenia can be used as a tool to identify preoperative high-risk patients, which can be considered to develop new postoperative risk prediction models.

Postnatal Protein Intake as a Determinant of Skeletal Muscle Structure and Function in Mice—A Pilot Study

“…While all individuals lose muscle mass and develop age-related muscle weakness (termed sarcopenia), some individuals are more likely to reach clinically relevant levels that profoundly impacts on their quality of life, resulting in a reduced ability to carry out everyday tasks and increased susceptibility to falling. Furthermore, sarcopenia has been associated with various musculoskeletal disorders and poor prognosis in the context of various age-related outcomes [ 6 , 7 ].…”

Is the measurement of sarcopenia associated with oncological disease in patients undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy?

“…The median PCI score (excluding PMP) was 11 [6][7][8][9][10][11][12][13][14][15][16][17][18] and the median PCI score (only PMP) was 25 (11-32) (Table 2). CC0 was achieved in the majority of patients excluding PMP (62 patients, 81.6%).…”

Sarcopenia as a predictor of outcome after transcatheter aortic valve implantation: protocol for systematic review and meta-analysis

“…Sarcopenia is demonstrated to herald adverse outcomes across a range of clinical conditions and is considered an independent marker of life quality and disease prognosis 10 11 14. Sarcopenia was observed to be a strong prognostic indicator for perioperative complications, which increased short-term and long-term postoperative mortality and morbidity,15–17 including cognitive impairment,18 mental disorders,19 acute kidney injury20 21 and even survival 17 22 23. Moreover, the sarcopenia cohort was associated with longer ICU and hospital stays,17 whose evidence was mainly observed in patients undergoing non-cardiac surgery.…”

Yet, no full consensus has been achieved on sarcopenia being a predictor of poor outcomes after TAVI.…”
