The role of body composition in diverticular disease
Background: Diverticular disease is a common, chronic inflammatory disease of the bowel. This study investigates the differences in body composition between patients with diverticular disease and those without. Methods: Appropriate patients were identified using a search of the radiology database. Demographic and disease information was gathered using scanned medical records. Body composition analysis was performed at level L3 using single-slice computed tomography techniques. Results: Two hundred seventy-one patients were included in this study: 83 controls, 93 with diverticulosis and 95 with diverticulitis. Diverticulitis and diverticulosis were associated with a significantly higher visceral fat area (VFA), than the control group (p < 0.001, p < 0.001). Diverticulitis and diverticulosis were associated with a significantly higher visceral fat area to subcutaneous fat area ratio (VFA:SCFA), than the control group (p = 0.005, p = 0.019). Only diverticulosis was associated with increased levels of extramyocellular fat, when compared to the control group (p = 0.001). Conclusion: Diverticular disease is associated with a higher amount and a higher proportion of visceral fat than seen in controls without diverticular disease
Prognostic role of alpha-fetoprotein in patients with hepatocellular carcinoma treated with repeat transarterial chemoembolisation
Determination of "borderline resectable" pancreatic cancer : a global assessment of 30 shades of grey
Background: Pancreatic ductal adenocarcinoma (PDAC) is an aggressive cancer with a poor prog-nosis. Accurate preoperative assessment using computed tomography (CT) to determine resectability is crucial in ensuring patients are offered the most appropriate therapeutic strategy. Despite the use of classification guidelines, any interobserver variability between reviewing surgeons and radiologists may confound decisions influencing patient treatment pathways. Methods: In this multicentre observational study, an international group of 96 clinicians (42 hepato-pancreatobiliary surgeons and 54 radiologists) were surveyed and asked to report 30 pancreatic CT scans of pancreatic cancer deemed borderline at respective multidisciplinary meetings (MDM). The degree of interobserver agreement in resectability among radiologists and surgeons was assessed and subgroup regression analysis was performed. Results: Interobserver variability between reviewers was high with no unanimous agreement. Overall interobserver agreement was fair with a kappa value of 0.32 with a higher rate of agreement among radiologists over surgeons. Conclusion: Interobserver variability among radiologists and surgeons globally is high, calling into question the consistency of clinical decision making for patients with PDAC and suggesting that central review may be required for studies of neoadjuvant or adjuvant approaches in future as well as ongoing quality control initiatives, even amongst experts in the field
