In hospitals through Europe and worldwide, the practices regarding hospital diets are very heterogeneous. Hospital diets are rarely prescribed by physicians, and sometimes the choices of diets are based on arbitrary reasons. Often prescriptions are made independently from the evaluation of nutritional status, and without taking into account the nutritional status. Therapeutic diets (low salt, gluten-free, texture and consistency modified, …) are associated with decreased energy delivery (i.e. underfeeding) and increased risk of malnutrition. The European Society for Clinical Nutrition and Metabolism (ESPEN) proposes here evidence-based recommendations regarding the organization of food catering, the prescriptions and indications of diets, as well as monitoring of food intake at hospital, rehabilitation center, and nursing home, all of these by taking into account the patient perspectives. We propose a systematic approach to adapt the hospital food to the nutritional status and potential food allergy or intolerances. Particular conditions such as patients with dysphagia, older patients, gastrointestinal diseases, abdominal surgery, diabetes, and obesity, are discussed to guide the practitioner toward the best evidence based therapy. The terminology of the different useful diets is defined. The general objectives are to increase the awareness of physicians, dietitians, nurses, kitchen managers, and stakeholders towards the pivotal role of hospital food in hospital care, to contribute to patient safety within nutritional care, to improve coverage of nutritional needs by hospital food, and reduce the risk of malnutrition and its related complications.

Importance

The lack of multidisciplinary workflow guidelines and clear definitions and classifications for neoplasms in and around the ampulla of Vater results in inconsistencies affecting patient care and research.

Objective

The PERIPAN international multidisciplinary consensus group aimed to standardize the multidisciplinary diagnostic workflow and achieve consensus on definitions and classifications in order to ensure proper classification and optimal diagnostic assessment and consequently to improve patient care and future research.

Design

An international team of 43 experts (pathologists, surgeons, radiologists, gastroenterologists, oncologists) from 12 countries identified knowledge gaps, reviewed 37061 articles, and proposed recommendations using the Scottish Intercollegiate Guidelines Network methodology (SIGN), including the Delphi methodology and the AGREEII tool for quality assessment and external validation.

Results

The 38 consensus questions and 51 recommendations provide guidance on the following key aspects: I. More specific anatomic criteria for the definition of what qualifies as “ampullary” neoplasms, their distinction from duodenal and common bile duct tumors, and clinicopathologic characteristics of anatomic subsets; II. Avoidance of the confusing term “periampullary” for final classification; III. Refined definitions of intestinal, pancreatobiliary and mixed subtypes, and introduction of rare histologic subtypes; IV. The use and limitations of immunohistochemical and molecular profiling; V. Biopsy acquisition; VI. Clinical information required for accurate pathology assessment of biopsies and ampullectomy specimens; VII. Key items to be included in pathology reports of endoscopic specimens.

Conclusions and Relevance

Recognition of the Brescia PERIPAN guidelines will allow a more accurate classification of true ampullary cancers and their differentiation from other “periampullary” tumors. This will have significant implications for endoscopic interpretation and management, staging, pathologic diagnosis and therapeutic evaluation as well as oncologic treatment of various anatomic and histologic subsets of ampullary tumors. This will enhance the quality of both clinical care and future research in this complex medical field.

Chronic mesenteric ischaemia is a severe and incapacitating disease, causing complaints of post-prandial pain, fear of eating and weight loss. Even though chronic mesenteric ischaemia may progress to acute mesenteric ischaemia, chronic mesenteric ischaemia remains an underappreciated and undertreated disease entity. Probable explanations are the lack of knowledge and awareness among physicians and the lack of a gold standard diagnostic test. The underappreciation of this disease results in diagnostic delays, underdiagnosis and undertreating of patients with chronic mesenteric ischaemia, potentially resulting in fatal acute mesenteric ischaemia. This guideline provides a comprehensive overview and repository of the current evidence and multidisciplinary expert agreement on pertinent issues regarding diagnosis and treatment, and provides guidance in the multidisciplinary field of chronic mesenteric ischaemia.
