Percutaneous endoscopic gastrostomy: confirming the clinical benefits far beyond anthropometry

Incidence of dysphagia-related safety incidents in older adults across feeding methods: A systematic review and meta-analysis

OBJECTIVE

Dysphagia-related safety incidents encompass near-miss events, no-harm occurrences, or harmful incidents associated with oral or enteral feeding methods. This systematic review and meta-analysis aimed to assess the incidence rates of dysphagia-related safety incidents in older adults across various feeding methods.

METHODS

A comprehensive literature search was conducted using PubMed, Embase, Web of Science, Cochrane Library, and CINAHL databases to identify studies reporting dysphagia-related safety incidents in older adults. The feeding methods analyzed included oral feeding, nasogastric (NG) tube feeding, and percutaneous endoscopic gastrostomy (PEG) tube feeding. Randomized controlled trials (RCTs), non-randomized studies, and cohort studies were included. The analysis adhered to the PRISMA guidelines, and meta-analytic outcomes were presented with 95% confidence intervals (CIs).

RESULTS

A total of 30 studies satisfied the inclusion criteria. The overall incidence rates of safety incidents were 13.8% for oral feeding, 23.9% for NG tube feeding, and 26.5% for PEG tube feeding. Aspiration pneumonia emerged as the most prevalent safety incident across all feeding methods, with incidence rates of 12.0% for oral feeding, 20.6% for NG tube feeding, and 12.4% for PEG tube feeding. Tube feeding methods were associated with diarrhea and wound infection. Additionally, specialized safety incidents were observed for each feeding method: suffocation in oral feeding; gastroesophageal reflux in NG tube feeding; and tube blockage, tube dislodgment, tube leakage, vomiting, nausea, site pain, gastrointestinal hemorrhage, and peritonitis in PEG tube feeding.

CONCLUSIONS

Dysphagia-related safety incidents in older adults demonstrated considerable variability in type and frequency across different feeding methods. Understanding these differences could provide healthcare professionals with valuable insights for targeted risk prediction and proactive management strategies to mitigate such incidents.

Percutaneous Endoscopic Gastrostomy in the 21st Century-An Overview of 1415 Consecutive Dysphagic Adult Patients

Background/Objectives: Percutaneous endoscopic gastrostomy (PEG) is recommended for long-term enteral nutrition in dysphagic patients. This study aims to characterize conditions motivating PEG, assess nutritional status on the gastrostomy day, evaluate survival and search for survival predictors. Methods: Retrospective study of adult patients who underwent PEG in a tertiary hospital from 2001 to 2023. Data collected included demographics, underlying disorders, nutritional status (anthropometry/laboratory evaluation) on the day of PEG and survival recorded until death or December 2023. Multivariable analysis was performed with Cox regression to search for survival predictors. Results: A total of 1415 patients were included (61.8% males, mean age 66.9 years); 66.4% presented a neurological disorder and 31.3% head and neck or esophageal cancers (HNC/EC). The mean BMI was 20.9 kg/m2, with 49.8% underweight. Albumin, transferrin and total cholesterol were low at 43.2%, 62.2% and 50%, respectively. Median overall survival was 11.1 months; 14.1% of deaths occurred within 4 weeks. HNC/EC patients showed lower survival than neurological patients. Potentially regressive neurological conditions presented longer survival than progressive ones. Predictors of increased survival included female gender, younger age, higher albumin and higher BMI. The protective effect of BMI and albumin was more pronounced in males than in females. Conclusions: Neurological disorders were the most frequent underlying conditions. Nearly half of the patients displayed malnutrition before PEG feeding. Although PEG-fed patients displayed a considerable median survival time, some died early without benefit from PEG. Patients with potentially regressive neurological conditions presented better outcomes. Female gender, younger age, higher albumin and higher BMI were associated with longer survival.

Futilidad en cirugía: el caso de la gastrostomía

Introducción. La nutrición se ha considerado tradicionalmente una necesidad básica y el garantizarla se ha asumido como una responsabilidad médica. Se cuestiona la utilización de procedimientos que permitan la nutrición artificial en situaciones clínicas limítrofes, en las cuales su beneficio puede ser limitado o nulo. En el presente estudio se busca determinar el éxito de un procedimiento quirúrgico, la gastrostomía, desde la perspectiva del beneficio para el paciente y, así, aproximarse a una definición de gastrostomía fútil. Métodos. Se llevó a cabo un estudio observacional, retrospectivo y analítico, basado en la revisión de las historias clínicas de los pacientes sometidos a gastrostomía abierta o endoscópica en el Hospital Universitario San Ignacio. El grupo de investigadores principales analizaron los datos para determinar si las gastrostomías practicadas fueron fútiles o no lo fueron. Resultados. Se incluyeron 145 pacientes tratados durante el periodo del 2015 al 2018 y en el 53 % de los cuales se cumplieron los criterios para considerar el procedimiento como fútil. Los procedimientos –108 endoscópicos y 37 abiertos–fueron practicados principalmente en pacientes con neoplasias de cabeza y cuello, y enfermedades neurológicas. Si bien no hubo mortalidad asociada con el procedimiento, 26 de los pacientes fallecieron en los primeros 15 días después de la intervención. Discusión. El determinar en qué condiciones se debe considerar la gastrostomía una intervención realmente beneficiosa es un desafío. Es necesario incorporar un análisis ético, antes de ofrecer este procedimiento, con el fin de minimizar las gastrostomías innecesarias que actualmente constituyen un problema global.

Percutaneous endoscopic gastrostomy – Too often? Too late? Who are the right patients for gastrostomy?

Percutaneous endoscopic gastrostomy is an established method to provide nutrition to patients with restricted oral uptake of fluids and calories. Here, we review the methods, indications and complications of this procedure. While gastrostomy can be safely and easily performed during gastroscopy, the right patients and timing for this intervention are not always chosen. Especially in patients with dementia, the indication for and timing of gastrostomies are often improper. In this patient group, clear data for enteral nutrition are lacking; however, some evidence suggests that patients with advanced dementia do not benefit, whereas patients with mild to moderate dementia might benefit from early enteral nutrition. Additionally, other patient groups with temporary or permanent restriction of oral uptake might be a useful target population for early enteral nutrition to maintain mobilization and muscle strength. We plead for a coordinated study program for these patient groups to identify suitable patients and the best timing for tube implantation.

Tube Feeding in Individuals with Advanced Dementia: A Review of Its Burdens and Perceived Benefits

Background

Dementia remains a growing concern for societies globally, particularly as people now live longer. About 90% of individuals with advanced dementia suffer from eating problems that lead to general health decline and ultimately impacts upon the physical, psychological, and economic wellbeing of the individuals, caregivers, and the wider society.

Objective

To evaluate the burdens and perceived benefits of tube feeding in individuals with advanced dementia.

Design

Narrative review.

Methods

Computerized databases, including PubMed, Embase, Medline, CINAHL, PsycInfo, and Google Scholar were searched from 2000 to 2019 to identify research papers, originally written in or translated into English language, which investigated oral versus tube feeding outcome in individuals with advanced dementia.

Results

Over 400 articles were retrieved. After quality assessment and careful review of the identified articles, only those that met the inclusion criteria were included for review.

Conclusion

Tube feeding neither stops dementia disease progression nor prevents imminent death. Each decision for feeding tube placement in individuals with advanced dementia should be made on a case-by-case basis and involve a multidisciplinary team comprising experienced physicians, nurses, family surrogates, and the relevant allied health professionals. Careful considerations of the benefit-harm ratio should be discussed and checked with surrogate families if they would be consistent with the wishes of the demented person. Further research is required to establish whether tube feeding of individuals with advanced dementia provides more burdens than benefits or vice-versa and evaluate the impacts on quality of life and survival.
