Metabolic and Nutritional Issues after Lower Digestive Tract Surgery: The Important Role of the Dietitian in a Multidisciplinary Setting

Many patients undergo small bowel and colon surgery for reasons related to malignancy, inflammatory bowel disease (IBD), mesenteric ischemia, and other benign conditions, including post-operative adhesions, hernias, trauma, volvulus, or diverticula. Some patients arrive in the operating theatre severely malnourished due to an underlying disease, while others develop complications (e.g., anastomotic leaks, abscesses, or strictures) that induce a systemic inflammatory response that can increase their energy and protein requirements. Finally, anatomical and functional changes resulting from surgery can affect either nutritional status due to malabsorption or nutritional support (NS) pathways. The dietitian providing NS to these patients needs to understand the pathophysiology underlying these sequelae and collaborate with other professionals, including surgeons, internists, nurses, and pharmacists. The aim of this review is to provide an overview of the nutritional and metabolic consequences of different types of lower gastrointestinal surgery and the role of the dietitian in providing comprehensive patient care. This article reviews the effects of small bowel resection on macronutrient and micronutrient absorption, the effects of colectomies (e.g., ileocolectomy, low anterior resection, abdominoperineal resection, and proctocolectomy) that require special dietary considerations, nutritional considerations specific to ostomized patients, and clinical practice guidelines for caregivers of patients who have undergone a surgery for local and systemic complications of IBD. Finally, we highlight the valuable contribution of the dietitian in the challenging management of short bowel syndrome and intestinal failure.

Management of long-term home parenteral nutrition: Historical perspective, common complications, and patient education and training

Intestinal failure (IF) is a rare disease that requires ongoing intravenous supplementation to sustain growth and health. Advancements in parenteral nutrition (PN) and central venous access in the 1960s and 1970s transformed a life-limiting disease to a chronic one in which patients are able to administer hydration, electrolytes, micronutrients, and macronutrients in the comfort of their home. However, despite ongoing advancements in the field of home PN (HPN), complications-whether related to central venous catheters or PN itself-remain common and can be associated with significant morbidity and mortality. Central venous access can be associated with thrombosis, central line-associated bloodstream infection, or damage and can result in loss of access over time. PN can be associated with IF-associated liver disease or hyperglycemia. The key to preserving central venous access and quality of life and maintaining health for patients with chronic IF (CIF) is education focused on prevention and prompt management of CIF complications as they arise. This education typically takes place at the time of initiation of HPN, either in the hospital setting or in the patient's home. The present manuscript describes the historical progression of HPN, prevalence and characteristics of CIF, and an in-depth discussion of the most common catheter-related and PN-related complications and their management, along with a discussion of our education and training process.

ELABORATION AND VALIDATION OF A MULTI-PROFESSIONAL EDUCATIONAL BOOKLET FOR CAREGIVERS OF PATIENTS IN HOME ENTERAL NUTRITION THERAPY

ABSTRACT Objective: to elaborate and validate face and content of a multi-professional educational booklet for the education of caregivers of patients in use of Home Enteral Nutrition Therapy. Method: a methodological study, conducted in two stages: (1) elaboration of the educational booklet, divided in four phases; and (2) validation of the educational material by 12 experts. A minimum agreement rate of 80% was considered to ensure validation of the material. Results: the material is structured in 16 items that were considered pertinent by the experts. Content assessment by the experts presented a global Content Validity Index of 0.87. The agreement level of the categories assessed varied from 83% to 90%. The suggestions in relation to content, clarity, pertinence and relevance were addressed and modified for the final version of the material. Conclusion: the educational booklet is considered valid regarding content. It is suggested that it may contribute to the understanding in health education in caregivers and family members of patients in use of enteral nutrition therapy.

Guidelines for gastrostomy tube placement and enteral nutrition in patients with severe, refractory hypoglycemia after gastric bypass

BACKGROUND

Postbariatric hypoglycemia (PBH) affects up to 38% of Roux-en-Y gastric bypass (RYGB) patients. Severe cases are refractory to diet and medications. Surgical treatments including bypass reversal and pancreatectomy are highly morbid and hypoglycemia often recurs. We have developed a highly effective method of treatment by which enteral nutrition administered through a gastrostomy (G) tube placed in the remnant stomach replaces oral diet: if done correctly this reverses hyperinsulinemia and hypoglycemia, yielding substantial health and quality of life benefits for severely affected patients.

OBJECTIVES

To provide clinical guidelines for placement of a G-tube to treat postRYGB hypoglycemia, including candidate selection, preoperative evaluation, surgical considerations, and post-RYGB management.

SETTING

Stanford University Hospital and Clinics.

METHODS

Based on our relatively large experience with placing and managing G-tubes for PBH treatment, an interdisciplinary task force developed guidelines for practitioners.

RESULTS

A team approach (endocrinologist, dietitian, surgeon, psychologist) is recommended. Appropriate candidates have a history of RYGB, severe hypoglycemia refractory to medical-nutrition therapy, and significantly affected quality of life. Preoperative requirements include education and expectation setting, determination of initial enteral feeding program, and establishing service with a home enteral provider. Close postoperative follow-up is needed to ensure success and may require adjustments in formula and mode/rate of delivery to optimize tolerance and meet nutritional goals. G-tube nutrition must fully replace oral nutrition to prevent hypoglycemia.

CONCLUSIONS

G-tube placement in the remnant stomach represents a relatively well-tolerated and effective treatment for severe, refractory hypoglycemia after RYGB.

Navigating the Challenges of Home Parenteral Nutrition

Providing parenteral nutrition at home has significant challenges for both patients and providers alike. Some of these challenges are systemic and are secondary to the way the healthcare system is designed to deliver care. Others are more practical and require educating patients and their families to ensure success at home. Overall, the nutrition support team was designed to help deal with these challenges in an effective way. The changing realities of the modern health system are challenging the nutrition support team to adapt to new obstacles. Providing patients with the tools to succeed at home requires a significant amount of time and investment but will pay dividends in the future as patients thrive for years to come.

Challenges and Obstacles of Long-Term Home Parenteral Nutrition

Patients receiving long-term home parenteral nutrition (HPN) and clinicians managing their care face complex challenges not fully addressed by existing clinical practice guidelines. This review aims to increase awareness of some of the challenges encountered when managing patients receiving HPN and provide strategies for management. The ability to optimally manage these patients starts with involvement of a qualified team of clinicians, which is sometimes difficult to find. There are unique challenges related to the parenteral nutrition (PN) prescribing and compounding process that are not typically encountered with inpatient use. Clear communication is required between the HPN prescriber/team and the home infusion pharmacist to prevent errors related to misinterpretation of the order and PN product shortages. Dependency on HPN and living with chronic disease create a number of psychosocial, financial, and other lifestyle restrictions that can negatively impact a patient's quality of life. HPN nonadherence is a challenge that complicates the clinician's ability to accurately assess and make appropriate adjustments to therapy. HPN adherence may be improved by incorporating a patient-centered approach to care that allows patients to prioritize those issues most meaningful and valuable to them. Patient-centered care also encourages self-care and relies on a high level of HPN education. Clinicians are encouraged to use an interactive interview style when engaging patients to prioritize goals of care and make self-motivated decisions for change. In spite of challenges, HPN therapy has allowed patients the ability to maintain adequate nutrition and thrive in the home setting when the oral/enteral route fails.
