Long term effects of pancreatico-duodenectomyThis observational study explores the impact of pre and post operative sarcopenia on surgical outcomes and tolerance of adjuvant chemotherapy. The study also explores long term implications such as micronutrient deficiency, onset of type 3c diabetes, other gastrointestinal complications and osteoporosis.

Malnutrition in chronic pancreatitis is complex and multifactorial, with malabsorption, pain, toxic dependencies and co-morbidities, such as diabetes, each playing a role. The aims of this systematic review were to assess the impact of nutritional intervention on markers of nutritional status in this complex patient group, A systematic review of EMBASE and PubMed was carried out in February 2020, identifying 2620 articles. After screening to exclude those reporting short term changes (less than 3 months), with only one data point, or in the wrong population, eight papers were selected for analysis. Seven studies documented the impact of a nutritional intervention, one was an observational study only. Overall, studies were limited by predominantly retrospective designs, heterogenous populations and poor control of potentially confounding variables. Data could not be combined due to variability in reporting methods. All studies exploring nutritional intervention, whether that consisted of advice by a specialist dietitian, dose escalation of pancreatic enzymes, oral nutritional supplements or enteral feeding, demonstrated improved body weight and pain control, whereas patients who did not receive an intervention deteriorated nutritionally. Patients with chronic pancreatitis benefit from nutritional intervention. Further work is required to explore the impact of nutritional intervention on body composition and functional outcomes.
Background and aims Patients with pancreatic cancer often experience significant deterioration in nutritional status over time. Malnutrition is complex and multifactorial, with malabsorption, pain, toxic dependencies, co-morbidities and malignant processes all playing a role. The aims of this systematic review were to assess nutritional changes over time and identify tolerance of nutritional intervention, thus identifying potential areas for further research to improve patient outcomes. Materials and methods A systematic review of MEDLINE, EMBASE and PubMed was carried out in February 2020, identifying 2620 articles. After screening to exclude those reporting short-term measures, with only one data point, or in the wrong population, thirteen papers were selected for analysis (four trials in neo-adjuvant treatment, five in populations undergoing palliative treatment for pancreatic cancer, and four in mixed populations undergoing pancreatic resection). Results Overall, studies were limited by predominantly retrospective designs, and poor control of potentially confounding variables. Meta-analysis could not be performed due to heterogenicity in study design and reporting methods. Surgery in mixed cohorts did not appear to result in weight loss. Only one small intervention study was identified. Patients with pancreatic cancer experienced a decline in nutritional status, with 44-63% of patients undergoing neoadjuvant chemotherapy having low muscle mass prior to starting treatment. Conclusion There is a paucity of data regarding nutritional intervention in pancreatic cancer. Future work should include the use of validated functional and clinical assessment tools to further explore the impact of nutritional intervention, and the relationship between nutritional status and outcome.
