The safe use of percutaneous gastrostomy for enteral nutrition in patients with Crohn's disease

ESPEN guideline on Clinical Nutrition in inflammatory bowel disease

The present guideline is an update and extension of the ESPEN scientific guideline on Clinical Nutrition in Inflammatory Bowel Disease published first in 2017. The guideline has been rearranged according to the ESPEN practical guideline on Clinical Nutrition in Inflammatory Bowel Disease published in 2020. All recommendations have been checked and, if needed, revised based on new literature, before they underwent the ESPEN consensus procedure. Moreover, a new chapter on microbiota modulation as a new option in IBD treatment has been added. The number of recommendations has been increased to 71 recommendations in the guideline update. The guideline is aimed at professionals working in clinical practice, either in hospitals or in outpatient medicine, and treating patients with IBD. General aspects of care in patients with IBD, and specific aspects during active disease and in remission are addressed. All recommendations are equipped with evidence grades, consensus rates, short commentaries and links to cited literature.

Percutaneous endoscopic gastrostomy placement in paediatric Crohn's disease patients contributes to both improved nutrition and growth

AIM

This paper describes the outcomes of gastrostomy feeding in patients with Crohn's disease (CD).

METHODS

Patients with CD who attended the Royal Hospital for Children, Glasgow and received gastrostomy feeding for at least two years between 2003 and 2010 were identified from the clinical database. The data recorded included the anthropometric data, CD phenotype, the surgical technique that was used, complications, medication, feed type, median feed, calories, volume and clinical outcomes.

RESULTS

The study identified 16 patients (14 male) who had a gastrostomy inserted using a pull technique at a median age of 12.6 years. Of these two required laparoscopic placement. Short-term complications lasting less than one month were experienced by nine (56%) patients and one (6%) experienced long-term complications. Anthropometry significantly improved at follow-up compared to baseline: at 12 months, the body mass index z-score was 1.11 (p = 0.005) and the weight z-score was 0.19 (p < 0.05). At 24 months, the height z-score was -1.03 (p = 0.04). The daily median volume and calories from feeds increased significantly from baseline to post-PEG insertion, from 400 to 738 mL and 705 to 860 kcal/day (p ≤ 0.01).

CONCLUSION

Gastrostomy feeding for paediatric patients with CD was associated with improved nutrition, weight gain and growth outcomes.

Nutritional management of the patient with Crohn's disease

Active Crohn's disease often co-exists with malnutrition and requires input from the inflammatory bowel disease multidisciplinary team in order to assess, prevent and treat the complications of both malnutrition and active disease.

Nutritional management of Crohn's disease

Nutritional care and therapy forms an integral part of the management of patients with Crohn's disease (CD). Nutritional deficiencies result from reduced oral intake, malabsorption, medication side effects and systemic inflammation due to active disease. Enteral nutrition has a role in support for the malnourished patient, as well as in primary therapy to induce and maintain remission. The use of parenteral nutrition in CD is mainly limited to the preoperative setting or for patients with intestinal failure, but does not offer any additional advantage over EN in disease control. Dietary modifications, including elimination-reintroduction diets and a low fermentable, oligosaccharides, disaccharides, monosaccharides and polyols (FODMAP) diet may improve symptoms but there are currently no data to suggest that these approaches have any role in the induction or maintenance of remission.

Nutrition in inflammatory bowel disease

The diet of industrialized nations may contribute to the pathogenesis of both ulcerative colitis (UC) and Crohn disease (CD). Malnutrition is relatively unusual in UC, but in CD, which often affects the small intestine, it is frequent and may be severe. Nutrition support is therefore frequently indicated. First principles of artificial nutrition can be applied effectively using the gut whenever possible. Parenteral nutrition is generally required only in those with short bowel syndrome. An increasing literature (especially in pediatrics) favors the use of defined exclusive enteral nutrition (EN) in the primary treatment of active CD. Controlled trials are, however, lacking, and recommendations are accordingly not of the highest rank. It appears that in this context, simple polymeric regimens are usually sufficient, and there is currently insufficient evidence to make a strong recommendation for disease-specific feeds. In the maintenance of remission in CD, controlled data demonstrate that defined EN reduces the risk of relapse requiring steroid treatment. There are no data in support of primary nutrition therapy in UC either in management of the acute flare or in maintenance. In conclusion, nutrition therapy in adults with inflammatory bowel disease is probably both undervalued and underused, but the evidence base needs to be strengthened to confirm its efficacy, determine better those patients most likely to benefit, and optimize the regimens to be employed.

ESPEN Guidelines on Enteral Nutrition: Gastroenterology

Undernutrition as well as specific nutrient deficiencies have been described in patients with Crohn's disease (CD), ulcerative colitis (UC) and short bowel syndrome (SBS). The present guideline gives evidence-based recommendations for the indication, application and type of formula of enteral nutrition (EN) (oral nutritional supplements (ONS) or tube feeding (TF)) in these patients. It was developed in an interdisciplinary consensus-based process in accordance with officially accepted standards and is based on all relevant publications since 1985. ONS and/or TF in addition to normal food is indicated in undernourished patients with CD or CU to improve nutritional status. In active CD EN is the first line therapy in children and should be used as sole therapy in adults mainly when treatment with corticosteroids is not feasible. No significant differences have been shown in the effects of free amino acid, peptide-based and whole protein formulae for TF. In remission ONS is recommended only in steroid dependent patients in CD. In patients with SBS TF should be introduced in the adaptation phase and should be changed with progressing adaptation to ONS in addition to normal food.
