Parenteral and Enteral Nutrition: A Bridge to Healing and Biological Therapy in a Patient With Enterocutaneous Fistula and Sepsis Complicated Crohn's Disease

Inpatient Nutritional Considerations in Inflammatory Bowel Disease

PURPOSE OF REVIEW

This review aims to explain the causes, diagnosis, and treatment of malnutrition in hospitalized patients with inflammatory bowel disease (IBD), focusing on both adults and children.

RECENT FINDINGS

Malnutrition is common among IBD patients, affecting up to 85% of individuals, and is linked to higher rates of illness, death, and longer hospital stays. Recent studies highlight the importance of early detection using tools like the Subjective Global Assessment (SGA) and handgrip strength tests. Nutritional interventions-such as exclusive enteral nutrition (EEN) and parenteral nutrition (PN)-have proven effective in inducing remission and improving patient outcomes, especially in pediatric Crohn's disease. New evidence suggests that optimizing nutrition before and after surgery, as well as using immunonutrition, may reduce postoperative complications. Early identification and management of malnutrition in hospitalized IBD patients may be important for improving clinical outcomes. Using appropriate nutritional screening tools and creating personalized nutrition plans can help with recovery, decrease hospital stays, and improve quality of life. Further research is needed to develop standard protocols for nutritional assessment and treatment in this patient population.

Risk Factors for Gallstones in Crohn's Disease: A Systematic Review and Meta-Analysis

BACKGROUND

Crohn's disease (CD) have an increased risk of gallstone disease. We aimed to systematically evaluate the prevalence rate and relevant risk factors of gallstones in CD patients.

METHODS

A comprehensive search of PubMed, Embase, and Web of Science databases from inception to September 10, 2023, identified studies investigating risk factors for gallstone development among CD patients. Gender, age, body mass index, disease duration, disease site, stenosis, prior surgery, hospitalization times, corticosteroids, immunomodulators, and total parenteral nutrition (TPN) were assessed as potential risk factors. Odds ratios (OR) and confidence intervals (CI) were calculated.

RESULT

Among 1184 articles, 11 observational studies (3588 patients) were included. The prevalence of CD patients with gallstones was approximately 14.7%. Factors significantly associated with increased gallstone risk included Age ≥ 40 years old (OR 3.06, 95% CI 2.09- 4.48), disease duration > 15 years (OR 3.01, 95% CI 2.06-4.42), lifetime surgery(OR 2.50, 95% CI 1.99-3.12), disease located in ileocolon (OR 1.38, 95% CI 1.04-1.83) and ileocecal(OR 1.93, 95% CI 1.16-3.21), multiple hospitalizations(OR 4.26, 95% CI 2.43-7.46), corticosteroid treatments(OR 2.65, 95% CI 1.52-4.63), immunomodulator therapy(OR 1.94, 95% CI 1.12-3.38), and TPN use(OR 2.66, 95% CI 1.29-5.51). Sex, stenosis, overweight, or low weight did not significantly increase the risk of gallstone developing.

CONCLUSION

Age, long disease duration, specific disease locations (ileocolon, ileocecal), surgery, number of hospitalizations, corticosteroids, immunomodulator therapy, and TPN were identified as factors that increased the risk of gallstones in CD patients. About 14.7% of CD patients experience gallstones, so raising awareness and implementing prevention are needed.

Use of oral diet and nutrition support in management of stricturing and fistulizing Crohn's disease

Crohn's disease (CD), a form of inflammatory bowel disease, involves chronic inflammation within the gastrointestinal tract. Intestinal strictures and fistulas are common complications of CD with varying severity in their presentations. Modifications in oral diet or use of exclusive enteral nutrition (EEN) are common approaches to manage both stricturing and fistulizing disease, although supporting research evidence is generally limited. In the preoperative period, there is strong evidence that EEN can reduce surgical complications. Parenteral nutrition (PN) is often utilized in the management of enterocutaneous fistulas, given that oral diet and EEN may potentially increase output in proximal fistulas. This narrative review highlights the current practices and evidence for the roles of oral diet, EEN, and PN in treatment and management of stricturing and fistulizing CD.

Timing of individualized surgical intervention in Crohn’s disease

Crohn’s disease (CD) is a chronic inflammatory disorder of the gastrointestinal tract with an increasing incidence worldwide. Comprehensive therapy for CD focuses on symptom control and healing the intestinal mucosa to improve the quality of life and prevent complications. Surgical intervention plays a vital role in comprehensive therapy. However, deciding the optimal timing for surgical intervention has long been a focus of controversy. This review provides insights into the timing of surgery for CD and guides clinicians in daily treatment.

Oligomeric Formulas in Surgery: A Delphi and Consensus Study

Nutritional management of patients with intestinal failure often includes the use of oligomeric formulas. Implementing the use of oligomeric formulas in surgical patients with maldigestion or malabsorption could be a nutritional strategy to be included in clinical protocols. We aim to generate knowledge from a survey focused on the effectiveness of nutritional therapy with oligomeric formulas with Delphi methodology. Each statement that reached an agreement consensus among participants was defined as a median consensus score ≥7 and as an interquartile range ≤3. The use of oligomeric formulas in surgical patients, starting enteral nutrition in the post-operative phase in short bowel syndrome and in nonspecific diarrhea after surgical procedures, could improve nutritional therapy implementation. Stakeholders agreed that early jejunal enteral nutrition with oligomeric formula is more effective compared to intravenous fluid therapy and it is useful in patients undergoing upper gastro-intestinal tract major surgery when malabsorption or maldigestion is suspected. Finally, oligomeric formulas may be useful when a feeding tube is placed distally to the duodenum. This study shows a practical approach to the use of oligomeric formulas in surgical patients with intestinal disorders and malabsorption, and it helps clinicians in the decision-making process.

Nutritional Intervention Facilitates Food Intake after Epilepsy Surgery

BACKGROUND

We investigated whether nutritional intervention affected food intake after epilepsy surgery and if intravenous infusions were required in patients with epilepsy. We hypothesized that postoperative food intake would be increased by nutritional intervention. The purpose of this study was to compare postoperative food intake in the periods before and after nutritional intervention.

METHODS

Between September 2015 and October 2020, 124 epilepsy surgeries were performed. Of these, 65 patients who underwent subdural electrode placement followed by open cranial epilepsy surgery were studied. Postoperative total food intake, rate of maintenance of food intake, and total intravenous infusion were compared in the periods before and after nutritional intervention.

RESULTS

A total of 26 females and 39 males (age range 3-60, mean 27.1, standard deviation (SD) 14.3, median 26 years) were enrolled. Of these, 18 females and 23 males (3-60, mean 28.2, SD 15.1, median 26 years) were in the pre-nutritional intervention period group, and eight females and 16 males (5-51, mean 25.2, SD 12.9, median 26.5 years) were in the post-nutritional intervention period group. The post-nutritional intervention period group showed significantly higher food intake (p = 0.015) and lower total infusion (p = 0.006) than the pre-nutritional intervention period group.

CONCLUSION

The nutritional intervention increased food intake and also reduced the total amount of intravenous infusion. To identify the cut-off day to cease the intervention and to evaluate whether the intervention can reduce the complication rate, a multicenter study with a large number of patients is warranted.

A modern multidisciplinary approach to the treatment of enterocutaneous fistulas in Crohn's disease patients

INTRODUCTION

Enterocutaneous fistulas (ECFs) is a manifestation of penetrating Crohn's disease (CD) that is challenging to treat and has considerable morbidity and mortality rates.

AREAS COVERED

This review aims to explore the practical and updated principles for the optimal treatment of ECFs in CD patients.

EXPERT OPINION

Optimal ECF management requires a multidisciplinary approach. Treatment first includes fluid resuscitation and electrolyte rebalancing with control of sepsis by means of antibiotics and, when indicated, drainage of infected collections. Subsequent therapeutic steps include nutritional support, control of the fistula output and treatment of peristomal skin. Anti-TNF-α therapy seems to have limited utility only after sepsis is resolved and intestinal stenosis excluded. However, ECFs heal in only approximately one-third of cases without surgical intervention. Thus, correct surgical timing combined with adequate nutritional support, sepsis resolution and skin care is considered the appropriate preoperative setting.
