Abstract
BACKGROUND Sarcopenia is associated with adverse perioperative outcomes in patients undergoing operations for malignancy, but its influence on patients undergoing elective colectomy for diverticulitis is unknown. We hypothesized that sarcopenia is associated with adverse perioperative events in patients undergoing elective colectomy for diverticulitis. METHODS Comorbidities, operative characteristics, and postoperative complications were extrapolated from our institutional EMR in patients undergoing elective colectomy for diverticulitis from 2016 to 2020. Sarcopenia was calculated using perioperative imaging and defined by standard skeletal muscle index (SMI) and psoas muscle index (PMI) thresholds. Univariate analysis was used to compare sarcopenic and non-sarcopenic patients. RESULTS 148 patients met inclusion criteria. Using SMI thresholds, 95 patients (64%) were sarcopenic. With SMI criteria, sarcopenic patients were older (67 vs 52 years old; P < .01) and had lower BMIs (26.2 vs 34.0, respectively; P < .001) than non-sarcopenic patients. There were no differences in baseline characteristics, postoperative complications, and non-home discharge between groups (P > .05 for all). Postoperative length of stay was greater in sarcopenic patients (3 IQR 2-5 vs 2 IQR 2-3 days; P < .01). Using PMI thresholds, 68 (46%) met criteria for sarcopenia. Using PMI thresholds, sarcopenic patients were older (68 vs 57.5 years old; P < .01) and had lower BMIs (25.8 vs 32.8; P < .01). There were no differences in comorbidities or measured operative outcomes between groups (P > .05 for all), other than postoperative length of stay which was longer in the sarcopenic group (3.5 IQR 3-5 vs 2 IQR 2-3; P < .01). CONCLUSIONS Incidence of sarcopenia was high in patients undergoing elective colectomy for diverticulitis in our practice, but sarcopenia was not associated with adverse perioperative outcomes. In select patients, elective colectomy for diverticulitis can be safely performed in the presence of sarcopenia.

Abstract
BACKGROUND Surgeons have historically used age as a preoperative predictor of postoperative outcomes. Sarcopenia, the loss of skeletal muscle mass due to disease or biological age, has been proposed as a more accurate risk predictor. The prognostic value of sarcopenia assessment in surgical patients remains poorly understood. Therefore, the authors aimed to synthesize the available literature and investigate the impact of sarcopenia on perioperative and postoperative outcomes across all surgical specialties. METHODS The authors systematically assessed the prognostic value of sarcopenia on postoperative outcomes by conducting a systematic review and meta-analysis according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, searching the PubMed/MEDLINE and EMBASE databases from inception to 1st October 2022. Their primary outcomes were complication occurrence, mortality, length of operation and hospital stay, discharge to home, and postdischarge survival rate at 1, 3, and 5 years. Subgroup analysis was performed by stratifying complications according to the Clavien-Dindo classification system. Sensitivity analysis was performed by focusing on studies with an oncological, cardiovascular, emergency, or transplant surgery population and on those of higher quality or prospective study design. RESULTS A total of 294 studies comprising 97 643 patients, of which 33 070 had sarcopenia, were included in our analysis. Sarcopenia was associated with significantly poorer postoperative outcomes, including greater mortality, complication occurrence, length of hospital stay, and lower rates of discharge to home (all P <0.00001). A significantly lower survival rate in patients with sarcopenia was noted at 1, 3, and 5 years (all P <0.00001) after surgery. Subgroup analysis confirmed higher rates of complications and mortality in oncological (both P <0.00001), cardiovascular (both P <0.00001), and emergency ( P =0.03 and P =0.04, respectively) patients with sarcopenia. In the transplant surgery cohort, mortality was significantly higher in patients with sarcopenia ( P <0.00001). Among all patients undergoing surgery for inflammatory bowel disease, the frequency of complications was significantly increased among sarcopenic patients ( P =0.007). Sensitivity analysis based on higher quality studies and prospective studies showed that sarcopenia remained a significant predictor of mortality and complication occurrence (all P <0.00001). CONCLUSION Sarcopenia is a significant predictor of poorer outcomes in surgical patients. Preoperative assessment of sarcopenia can help surgeons identify patients at risk, critically balance eligibility, and refine perioperative management. Large-scale studies are required to further validate the importance of sarcopenia as a prognostic indicator of perioperative risk, especially in surgical subspecialties.

Abstract
BACKGROUND Risk assessment for emergency laparotomy (EL) is important for guiding decision-making and anticipating the level of perioperative care in acute clinical settings. While established tools such as the American College of Surgeons National Surgical Quality Improvement Program calculator (ACS-NSQIP), the National Emergency Laparotomy Audit Risk Prediction Calculator (NELA) and the Portsmouth Physiological and Operative Severity Score for the enumeration of Mortality and Morbidity calculation (P-POSSUM) are accurate predictors for mortality, there has been increasing recognition of the benefits from including measurements for frailty in a simple and quantifiable manner. Psoas muscle to 3rd lumbar vertebra area ratio (PM:L3) measured on CT scans was proven to have a significant inverse association with 30-, 90- and 365-day mortality in EL patients. METHODS A retrospective analysis was conducted of 500 patients admitted to four Australian hospitals who underwent EL during 2016-2017, and had contemporaneous abdomino-pelvic CT scans. Radiological sarcopenia was measured as PM:L3 ratios. ASC-NSQIP, NELA and P-POSSUM were retrospectively calculated. Univariate and multivariate logistic regression modelling was used to assess these ratios and scores, as well as American Society of Anaesthesiologists (ASA) classification separated into ASA I-III and IV/V (simplified ASA), as potential predictors of 30-, 90- and 365-day mortality. RESULTS PM:L3, simplified ASA, ACS-NSQIP, NELA and P-POSSUM were each statistically significant predictors of 30-day, 90-day and 365-day mortality (P < 0.001). Logistic regression models of 30-, 90- and 365-day mortality combining PM:L3 (P = 0.001) and simplified ASA (P < 0.001) exhibited AUCs of 0.838 (0.780, 0.896), 0.805 (0.751, 0.860) and 0.775 (0.729, 0.822), respectively, which were comparable to that of ACS-NSQIP and NELA. CONCLUSION Combining the semi-physiological parameter ASA classification with PM:L3 provides a quick and simple alternative to the more complex established risk assessment scores and is superior to PM:L3 alone.

Muscle mass and quality as predictors for complications, recurrence and length of hospital stay in acute uncomplicated diverticulitis: a retrospective cohort study. Scand J Gastroenterol 2023; 58:375-379.

Abstract
OBJECTIVES The aim of this study was to investigate the potential correlation between muscle mass/muscle quality and risk of complications or recurrence in patients presenting with acute uncomplicated diverticulitis. It was also to study if low muscle mass/quality correlated to prolonged hospital stay. MATERIALS AND METHODS The study population comprised 501 patients admitted to Helsingborg Hospital or Skåne University Hospital between 1 January 2015 and 31 December 2017, who had been diagnosed with acute uncomplicated diverticulitis and undergone computed tomography upon admission. The scans were used to estimate skeletal muscle mass and muscle radiation attenuation (an indicator for muscle quality). Skeletal muscle index was obtained by adjusting skeletal muscle mass to the patients' height. Values of below the fifth percentile of a normal population were considered low. RESULTS There were no differences between the patients with normal versus those with low skeletal muscle mass, skeletal muscle index or muscle radiation attenuation regarding risk of complications or recurrence of diverticular disease. However, as only 11 patients had complications, no conclusion as to a potential correlation can be made. Low muscle quality correlated to longer hospital stay, also when adjusting for other potential confounders. CONCLUSIONS Muscle mass/quality do not seem to serve as predictor of risk for recurrent disease in patients with acute uncomplicated diverticulitis. However, low muscle radiation attenuation was associated with prolonged hospital stay. This indicates that muscle quality, assessed by computed tomography scan, might be used in clinical practise to identify patients at risk of longer hospitalisation.

Abstract
BACKGROUND Despite the negative effect of sarcopenia on postoperative outcomes being well recognized in the elective setting, there remains a paucity of studies describing this phenomenon in the emergency laparotomy (EL) setting. This systematic review and meta-analysis aimed to compare short- and long-term postoperative outcomes following EL in patients with and without sarcopenia. METHODS A systematic review using PRISMA guidelines was used to identify studies comparing perioperative outcomes following EL for patients with and without sarcopenia. A subsequent meta-analysis was conducted. The following data were extracted from the included studies: patient demographics, pathology or type of operation performed for EL, post-operative mortality at inpatient, 30-day, 90-day and 1-year, and functional outcomes. A quality assessment of included studies was undertaken. RESULTS Twelve studies reporting the outcomes of sarcopenia following EL were identified. Sarcopenia was significantly associated with higher 30-day and 1-year mortality rates following EL (OR 3.50, P < 0.01; OR 3.49, P < 0.01, respectively). Additionally, sarcopenia was significantly associated with unfavourable functional outcomes at discharge following emergency laparotomy (OR 2.44, p < 0.01). CONCLUSION Opportunistically identified on cross-sectional imaging, sarcopenia is a valuable predictor of short- and long-term morbidity and mortality following EL. Further studies are required to identify the most appropriate diagnostic criteria of sarcopenia and better define this physiological phenomenon.

Abstract
BACKGROUND Emergency Laparotomy (EL) is recognized as high-risk surgery with high mortality. Established surgical risk assessment tools (NELA Risk Prediction Calculator, P-POSSUM, ACS-NSQIP) are accurate predictors of morbidity and mortality. However, their multicomponent complexity limits their use in practice. Sarcopenia is associated with poorer surgical outcomes. This study tests for an association between a simple measure of radiological sarcopenia and mortality in EL patients in an Australian cohort. METHODS A retrospective analysis was conducted of 500 patients admitted to four Australian hospitals who underwent EL during 2016-2017. All patients had a contemporaneous abdomino-pelvic CT scan. Radiological sarcopenia was measured as the ratio of total psoas muscle area (PM) to L3 vertebral body cross sectional area (PM:L3). Patients were followed up to 12 months. Primary outcomes were 30-, 90- and 365-day mortality. RESULTS The mean 30-day mortality predictions for NELA, P-POSSUM and ACS-NSQIP were 11.36%, 17.28% and 11.30% respectively. PM:L3 ratio was associated with 30-, 90- and 365-day mortality (P < 0.001) and sex (P < 0.001) and negatively correlated with age (r = -0.4612; P < 0.001). Radiological sarcopenia had a weak negative correlation with NELA (r = -0.2737; P < 0.001), P-POSSUM (r = -0.1880; P < 0.001) and ACS-NSQIP (r = -0.2351; P < 0.001). The latter three metrics were significantly correlated (r > 0.5696; P < 0.001). CONCLUSION Radiological sarcopenia (CT-assessed PM:L3) is a significant predictor of mortality in EL patients in Australia. The results of this study suggest that radiological sarcopenia is equivalent to established risk assessment tools. The more timely and easily accessible CT-assessed PM:L3 metric is potentially automatable and may have significant utility in clinical practice.

Abstract
BACKGROUND Diverticular disease remains one of the most common conditions in the western world. Up to 25% of patients with diverticular disease require hospitalization, 15-30% of those of which require surgical intervention. CT scoring systems have been proposed as means to drive assessment and stratify patients necessitating hospital intervention. To assess and correlate CT scoring systems with clinical and surgical outcomes. METHODS Retrospective cohort analysis at a single institution. Single institutional assessment with patients presenting to emergency with a CT diagnosed episode of acute diverticulitis. One hundred and eighty-nine patients were included in the study, 61% of which were male. Patient demographics, comorbidities, medications, biochemistry and inflammatory markers, type of complication following acute diverticulitis, operative/procedural intervention, hospital outcome and mortality were measured. CT scoring systems assessed included modified Hinchey, modified Neff, World Society of Emergency Surgery (WSES) and modified Siewert scoring systems. RESULTS Majority of patients had left-sided diverticulitis (91%) with localized air (88%) and pericolic abscess (49%) the most common radiological findings. 28% of patients required radiological and/or surgical management with 12% requiring intensive care unit (ICU) admission. There was a general trend for surgical/radiological intervention as the scores increased in severity. The four scoring systems were found to be statistically significant predictors of any intervention and of ICU admission with minimal statistical differences across the different scoring systems. CONCLUSION Radiological CT scores for complicated diverticulitis are at best, moderate predictors of clinical and surgical outcomes and may serve to guide management with minimal statistical differences across different scores.

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.

Abstract
Background The Naples Prognostic Score (NPS) has proven efficacy as a prognostic tool for postoperative outcomes in patients undergoing surgery for neoplastic diseases. However, the role of the NPS score in inflammatory surgical diseases has not yet been studied. We aimed to evaluate NPS predictive value in patients undergoing colectomy due to diverticulitis. Methods A single-center retrospective study including all patients who underwent colectomy for diverticulitis between July 2008 and March 2020 was established. Patients' demographics, clinical and surgical data were recorded and analyzed. Patients were scored on a scale of 0-4 and received one point for preoperation albumin <4 g/dL, cholesterol ≤180 mg/dL, Neutrophil to Lymphocyte Ratio >2.96, and Lymphocyte to Monocyte ≤4.44. Results Out of 3292 patients admitted because of diverticulitis during the study period, 159 patients (4.83%) underwent colectomy. Of those patients, fifty patients were eligible for NPS analysis. 35 patients (70%) were females with a mean age of 62.81 ± 14.51. Thirty-two (64%) patients underwent an elective operation. The postoperative complications rate was 36% (N = 18). The mortality rate was 6% (N = 3). ROC showed a strong association between the NPS and mortality (area = .88, P = .03) and wound infection (area = .78, P = .01). In patients who underwent urgent surgery, there was an association between NPS and re-operation ( P = .04). There was a correlation between NPS and Clavien-Dindo score (Spearman’s coefficient = .284, P = .045). Conclusions/Discussion The Naples prognostic score is an effective tool for predicting postoperative complications in patients undergoing colectomy for diverticulitis. It may assist the surgeon in deciding on extent of the operation for diverticulitis and in elective cases also on timing.

Abstract
Skeletal muscle wasting occurs in both chronic and acute diseases. Increasing evidence has shown this debilitating process is associated with short- and long-term outcomes in critical, cancer and surgical patients. Both muscle quantity and quality, as reflected by the area and density of a given range of attenuation in CT scan, impact the patient prognosis. In addition, ultrasound and bioelectrical impedance analysis (BIA) are also widely used in the assessment of body composition due to their bedside viability and no radioactivity. Mechanism researches have revealed complicated pathways are involved in muscle wasting, which include altered IGF1-Akt-FoxO signaling, elevated levels of myostatin and activin A, activation of NF-κB pathway and glucocorticoid effects. Particularly, central nervous system (CNS) has been proven to participate in regulating muscle wasting in various conditions, such as infection and tumor. Several promising therapeutic agents have been under developing in the treatment of muscle atrophy, such as myostatin antagonist, ghrelin analog, non-steroidal selective androgen receptor modulators (SARMs). Notably, nutritional therapy is still the fundamental support in combating muscle wasting. However, the optimizing and tailored nutrition regimen relies on accurate metabolism measurement and large clinical trials in the future. Here, we will discuss the current understanding of muscle wasting and potential treatment in clinical practice.

Abstract
Frailty assessment in patients admitted to intensive care is often limited using traditional clinical frailty assessment tools. Opportunistic use of contemporary computed tomography (CT) can provide an objective estimate of low skeletal muscle mass (sarcopenia) as a proxy for frailty. The aim of this study was to establish the prevalence of sarcopenia in an Australian intensive care unit (ICU) population and to examine the relationship between sarcopenia and clinical outcomes. We undertook a single centre retrospective study of 1085 adult patients admitted to a single ICU over 12 months. Patients with a contemporary CT scan including the L3 vertebral body were included. Patients were categorised as sarcopenic or non-sarcopenic using previously published data. A total of 279 patients with a mean age of 67 years had an eligible CT scan; 163 (58%) were male. Higher 30-day mortality was associated with the use of CRRT (continuous renal replacement therapy) during the ICU admission (OR 6.84, P < 0.001) and also associated with lower cross-sectional muscle area (odds ratio (OR) 0.98, P = 0.004). Sarcopenia was found to be highly prevalent in this particular Australian ICU population (68%) and associated with older age (68 versus 55 years, P < 0.001), lower body mass index (27 versus 32 kg m-2, P < 0.001), more comorbidities (3 versus 2, P = 0.009), and longer stays in hospital (279 versus 223 h, P = 0.043). As a continuous predictor, lumbar muscle mass was associated with 30-day mortality with and without adjusting for other covariates.

Abstract
PURPOSE OF REVIEW As many as two of every three major surgery patients are malnourished preoperatively - a diagnosis rarely made and treated even less frequently. Unfortunately, perioperative malnutrition is perhaps the least often identified surgical risk factor and is among the most treatable to improve outcomes. RECENT FINDINGS Two important perioperative nutrition guidelines were published recently. Both emphasize nutrition assessment as an essential component of preoperative screening. The recently published perioperative nutrition screen (PONS) readily identifies patients at malnutrition risk, allowing for preoperative nutritional optimization. The use of computerized tomography scan and ultrasound lean body mass (LBM) evaluation to identify sarcopenia associated with surgical risk and guide nutrition intervention is garnering further support. Preoperative nutrition optimization in malnourished patients, use of immunonutrition in all major surgery, avoidance of preoperative fasting, inclusion of postoperative high-protein nutritional supplements, and early postoperative oral intake have all recently been shown to improve outcomes and should be utilized. SUMMARY The recent publication of new surgical nutrition guidelines, the PONS score, and use of LBM assessments will allow better identification and earlier intervention on perioperative malnutrition. It is essential that in the future no patient undergoes elective surgery without nutrition screening and nutrition intervention when malnutrition risk is identified.

Abstract
BACKGROUND Obesity is becoming a bigger health problem every year. Current research shows that the obesity-related metabolic problems are strongly associated with visceral fat and not subcutaneous fat. Visceral obesity (VO) is associated with a worse postoperative outcome in multiple fields of abdominal surgery. On the other hand, muscle mass is related to better postoperative outcome. In rectal cancer patients, we studied the influence of visceral obesity and muscle mass on postoperative complications. METHODS The visceral fat area (VFA) and skeletal muscle area (SMA) were determined on preoperative CT scans in 406 patients. The preoperative comorbidity, per-operative outcome and postoperative complications were extracted retrospectively from the patient files. VO was defined as a VFA > 100 cm2. Correlations between body composition, postoperative complications and LOS were studied. RESULTS In our study, 67% of the patients were classified as visceral obese. Mean body mass index (BMI) was higher in the VO group (26.6 ± 3.5 vs 23.5 ± 2.8; p < 0.001). Visceral obese patients had a higher prevalence of cardiac comorbidity (29% vs 13% p = 0.001), hypertension (36% vs 20% p = 0.002) and diabetes mellitus (16% vs 5% p = 0.002). In addition, VO patients had more operative blood loss (431 vs 310 mL; p = 0.008), longer operating time (166 vs 149 min p = 0.003) and more wound infections (14% vs 8% p = 0.048). Visceral obesity was associated with more complications (OR: 1.63 p = 0.043) and longer LOS (risk estimate: 1.18 p = 0.009). CONCLUSION VO patients more often had a history of cardiac disease, hypertension and diabetes mellitus. Visceral obesity correlated with a worse outcome after surgery for rectal cancer.

Abstract
AIM The aim was to analyze the correlation between psoas muscle mass and mortality, as well as postoperative complications in patients treated for colonic perforation. PATIENTS AND METHODS A total of 46 patients met the study criteria. Patients were classified into an elderly (age, ≥75 years, n=24) and a younger group (age, <75 years, n=22). Background factors, postoperative data (including duration of hospital stay and discharge) were collected. The cross-sectional area of the psoas muscle area (PMA) was measured on the same day of operation. RESULTS The age/length of stay and PMA were significantly correlated in the younger group (p=0.0015, 0.023, respectively). Fifteen and six patients were discharged to return home, and 8 and 16 patients were transferred to another hospital, in the younger and elderly groups, respectively (p=0.02). Discharge was not correlated with the PMA in either group. CONCLUSION The total psoas muscle mass would be useful as a quick and convenient measure of sarcopenia in younger patients, but not elderly patients.

Abstract
Acute diverticulitis is a common condition that has been increasing in incidence in the United States. It is associated with increasing age, but the pathophysiology of acute diverticulitis is still being elucidated. It is now believed to have a significant contribution from inflammatory processes rather than being a strictly infectious process. There are still many questions to be answered regarding the optimal management of acute diverticulitis because recent studies have challenged traditional practices, such as the routine use of antibiotics, surgical technique, and dietary restrictions for prevention of recurrence.

Abstract
PURPOSE OF REVIEW We have significantly improved hospital mortality from sepsis and critical illness in last 10 years; however, over this same period we have tripled the number of 'ICU survivors' going to rehabilitation. Furthermore, as up to half the deaths in the first year following ICU admission occur post-ICU discharge, it is unclear how many of these patients ever returned home or a meaningful quality of life. For those who do survive, recent data reveals many 'ICU survivors' will suffer significant functional impairment or post-ICU syndrome (PICS). Thus, new innovative metabolic and exercise interventions to address PICS are urgently needed. These should focus on optimal nutrition and lean body mass (LBM) assessment, targeted nutrition delivery, anabolic/anticatabolic strategies, and utilization of personalized exercise intervention techniques, such as utilized by elite athletes to optimize preparation and recovery from critical care. RECENT FINDINGS New data for novel LBM analysis technique such as computerized tomography scan and ultrasound analysis of LBM are available showing objective measures of LBM now becoming more practical for predicting metabolic reserve and effectiveness of nutrition/exercise interventions. 13C-Breath testing is a novel technique under study to predict infection earlier and predict over-feeding and under-feeding to target nutrition delivery. New technologies utilized routinely by athletes such as muscle glycogen ultrasound also show promise. Finally, the role of personalized cardiopulmonary exercise testing to target preoperative exercise optimization and post-ICU recovery are becoming reality. SUMMARY New innovative techniques are demonstrating promise to target recovery from PICS utilizing a combination of objective LBM and metabolic assessment, targeted nutrition interventions, personalized exercise interventions for prehabilitation and post-ICU recovery. These interventions should provide hope that we will soon begin to create more 'survivors' and fewer victim's post-ICU care.
