Percutaneous endoscopic gastrostomy versus nasogastric tube feeding for adults with swallowing disturbances

Predictors for Failed Removal of Nasogastric Tube in Patients With Brain Insult

OBJECTIVE

To construct a prognostic model for unsuccessful removal of nasogastric tube (NGT) was the aim of our study.

METHODS

This study examined patients with swallowing disorders receiving NGT feeding due to stroke or traumatic brain injury in a regional hospital. Clinical data was collected, such as age, sex, body mass index (BMI), level of activities of daily living (ADLs) dependence. Additionally, gather information regarding the enhancement in Functional Oral Intake Scale (FOIS) levels and the increase in food types according to the International Dysphagia Diet Standardization Initiative (IDDSI) after one month of swallowing training. A stepwise logistic regression analysis model was employed to predict NGT removal failure using these parameters.

RESULTS

Out of 203 patients, 53 patients (26.1%) had experienced a failed removal of NGT after six months of follow-up. The strongest predictors for failed removal were age over 60 years, underweight BMI, total dependence in ADLs, and ischemic stroke. The admission prediction model categorized patients into high, moderate, and low-risk groups for removal failure. The failure rate of NGT removal was high not only in the high-risk group but also in the moderate-risk groups when there was no improvement in FOIS levels and IDDSI food types.

CONCLUSION

Our predictive model categorizes patients with brain insults into risk groups for swallowing disorders, enabling advanced interventions such as percutaneous endoscopic gastrostomy for high-risk patients struggling with NGT removal, while follow-up assessments using FOIS and IDDSI aid in guiding rehabilitation decisions for those at moderate risk.

Complexities of Long-Term Care With Gastro-Jejunal (GJ) Feeding Tubes and Enteral Migration During COVID-19 Pandemic Times: A Case Report

Gastro-jejunostomy tubes, or percutaneous endoscopic gastrostomy tubes with jejunal extension (PEG-J), hold a significant role in the long-term nutritional management of patients with poor oral intake. This can be for a variety of reasons; ranging from metabolic conditions, including diabetes mellitus, inherited or congenital conditions like Ehler Danlos syndrome, or patients with neurological disorders, such as stroke, advanced Parkinson's disease or multiple sclerosis. Although they are very helpful for the overall nutritional needs of such patients, they are associated with complications, including the dislodging of jejunal tubes. The need to promptly recognise, investigate and manage this, in a timely manner, is vital, particularly during the COVID-19 pandemic times, as such patients may be associated with multiple comorbidities.

Clinician's attitude to enteral nutrition with percutaneous endoscopic gastrostomy: a survey in China

BACKGROUND

Percutaneous endoscopic gastrostomy (PEG) is recommended for long-term enteral nutrition. However, long-term nasogastric (NGT) feeding is still commonplace in China. We surveyed Chinese clinicians' opinions toward PEG feeding in order to identify the potential barriers to acceptancy of PEG feeding.

METHODS

A self-reported questionnaire was developed and distributed to 600 doctors. Five-point Likert scales were used for most responses.

RESULTS

Of 525 respondents, the mainly nutritional support method was NGT while PEG was less used. Doctors working in the tertiary class A hospitals and radiotherapy department were more likely to choose PEG feeding (p = 0.000). Overall, 241 (46%) participants did not know PEG and 284 (54%) have different understanding degree of PEG. Age (p = 0.002), working life (p = 0.044) and professionalism (p = 0.005) were significantly related to the understanding of PEG. Levels of agreement was high (score of 3.47) for using PEG in patients with prolonged stroke-associated dysphagia. There was high agreement level in the statement that PEG was unnecessary when NGT could sustain the basic needs of patients, though better outcome can be predicted with PEG feeding. The highest scoring factor (score of 3.91) that influenced clinicians' choice of PEG was resistance from patients and families and the second one was the poor cooperation among departments (score of 3.80).

CONCLUSIONS

Doctors' insufficient knowledge of PEG feeding, resistance from patients and families, poor cooperation among departments, all these factors leading physicians to prefer more conservative treatment to avoid disputes rather than better ones.

Effect of an indwelling nasogastric tube on swallowing function in elderly post-stroke dysphagia patients with long-term nasal feeding

BACKGROUND

In clinical practice, a large number of post-stroke survivors require nasogastric tube (NGT) placement and nasal feeding for a relatively long period. However, its impact on the swallowing function remains largely unknown. This study examines the impact of prolonged placement of an NGT on the swallowing function of elderly post-stroke patients.

METHODS

The participants of this study were 30 elderly post-stroke patients who had been using an NGT for more than 2 months. A videofluoroscopic swallowing study (VFSS) was performed before and 5 h after removal of the NGT. The following parameters were analyzed and compared, the functional dysphagia scale (FDS), residue in the valleculae, residue in the pyriform sinuses, and the penetration-aspiration scale (PAS). In addition, prior to the VFSS, the pharynx and larynx were examined using a fiberoptic laryngoscope.

RESULTS

Significant differences were observed between the total scores of the FDS, pharyngeal transit times (PTTs), the residue in the valleculae, and the residue in the pyriform sinuses before and after the NGT removal, suggesting an improved swallowing function following the removal of the NGT. A significantly lower penetration-aspiration degree was found after removing the NGT compared with that before its removal. In addition, examinations using the fiberoptic laryngoscope showed that laryngopharyngeal edema was present in three quarters of the patients.

CONCLUSIONS

Our results demonstrate that prolonged placement of the NGT had a negative impact on the swallowing function of elderly post-stroke dysphagia patients, mainly on the pharyngeal phase.

Usefulness of Early Videofluoroscopic Swallowing Study in Acute Stroke Patients With Dysphagia

Objective

To demonstrate the usefulness of early videofluoroscopic swallowing study (VFSS) and to investigate change patterns in dietary methods in stroke patients with dysphagia.

Methods

The VFSS was performed within 7 days of stroke onset in neurologically stable patients. The patients were divided into three groups according to type of brain lesion: cortical lesion (CL), subcortical lesion (SCL), and brainstem/cerebellar lesion (BCL). Based on the VFSS results, this study investigated change patterns in feeding method and discrepancies in the aspiration risk predicted by the Water Swallowing Test (WST) and the VFSS. Complications, such as aspiration pneumonia, were also evaluated.

Results

A total of 163 patients met the inclusion criteria and the VFSS was performed within 7 days of stroke. Patients considered at risk for aspiration (Penetration-Aspiration Scale [PAS] scores of 6 to 8) were found in all three groups using the VFSS (47.5% of the CL group, 59.3% of the SCL group, and 47.9% of the BCL group). After early VFSS, 79.7% of the patients were assessed to require restricted feeding methods. A 19.0% discrepancy was found between the WST and VFSS results. At 3-week follow-up after the VFSS, aspiration pneumonia was observed in 12 patients (7.4%) with restricted feeding methods.

Conclusion

Early VFSS during the acute period can facilitate determination of the most appropriate feeding method, and support effective dysphagia management for stroke patients.

Tube Feeding among Elder in Long-Term Care Facilities: A Systematic Review and Meta-Analysis

OBJECTIVE

The use of tube feeding for elderly patients with poor nutritional intake is a ubiquitous method of feeding. This systematic review and meta-analysis were carried out to compare nutritional benefits of enteral feeding versus oral feeding in long-term care facilities.

SETTING

Databases including the Cochrane Library, ProQuest, PubMed, EMBASE, EBSCO, Web of Science and Google Scholar through April 2014 using keywords including enteral feeding, tube feeding or oral feeding combined with long term care facilities or nursing home.

PARTICIPANTS

Eight articles, with 841 participants were included in meta-analysis and 13 articles were included in systematic review. The elderly had to live in long-term care institutions and could not be on any mechanically assisted ventilation systems or be in any type of post-operative status.

MEASUREMENTS

The three investigators extracted and appraised data using the same study design, baseline characteristics, and outcomes, independently.

RESULTS

Following a systematic review, 13 articles out of 8218 original research articles were selected for this analysis. Meta-analysis of tube-fed patients found lower levels of hemoglobin (Weighted Mean Difference (WMD -0.21g/dl; 95% CI -0.42 to -0.01; p=0.04) and creatinine (WMD -0.08g/dl; 95% CI -0.17 to 0.00, p=0.05). Moreover, the results showed that there were no benefits regarding body mass index (BMI), albumin, dietary intake of proteins, total calories and fat.

CONCLUSIONS

The results show that tube feeding does not increase patients' nutrients absorption to improve nutritional status. Instead, these results indicate that oral feeding is better regarding some nutritional biochemical parameters.

Predictive Factors for Prophylactic Percutaneous Endoscopic Gastrostomy (PEG) Tube Placement and Use in Head and Neck Patients Following Intensity-Modulated Radiation Therapy (IMRT) Treatment: Concordance, Discrepancies, and the Role of Gabapentin

The prophylactic placement of a percutaneous endoscopic gastrostomy (PEG) tube in the head and neck cancer (HNC) patient is controversial. We sought to identify factors associated with prophylactic PEG placement and actual PEG use. Since 2010, data regarding PEG placement and use were prospectively recorded in a departmental database from January 2010 to December 2012. HNC patients treated with intensity-modulated radiation therapy (IMRT) were retrospectively evaluated from 2010 to 2012. Variables potentially associated with patient post-radiation dysphagia from previous literature, and our experience was evaluated. We performed multivariate logistic regression on these variables with PEG placement and PEG use, respectively, to compare the difference of association between the two arms. We identified 192 HNC patients treated with IMRT. Prophylactic PEG placement occurred in 121 (63.0 %) patients, with PEG use in 97 (80.2 %) patients. PEG placement was associated with male gender (p < .01), N stage ≥ N2 (p < .05), pretreatment swallowing difficulties (p < .01), concurrent chemotherapy (p < .01), pretreatment KPS ≥80 (p = .01), and previous surgery (p = .02). Concurrent chemotherapy (p = .03) was positively associated with the use of PEG feeding by the patient, whereas pretreatment KPS ≥80 (p = .03) and prophylactic gabapentin use (p < .01) were negatively associated with PEG use. The analysis suggests there were discrepancies between prophylactic PEG tube placement and actual use. Favorable pretreatment KPS, no pretreatment dysphagia, no concurrent chemotherapy, and the use of gabapentin were significantly associated with reduced PEG use. This analysis may help refine the indications for prophylactic PEG placement.

Percutaneous endoscopic gastrostomy versus nasogastric tube feeding for adults with swallowing disturbances

BACKGROUND

A number of conditions compromise the passage of food along the digestive tract. Nasogastric tube (NGT) feeding is a classic, time-proven technique, although its prolonged use can lead to complications such as lesions to the nasal wing, chronic sinusitis, gastro-oesophageal reflux, and aspiration pneumonia. Another method of infusion, percutaneous endoscopy gastrostomy (PEG), is generally used when there is a need for enteral nutrition for a longer time period. There is a high demand for PEG in patients with swallowing disorders, although there is no consistent evidence about its effectiveness and safety as compared to NGT.

OBJECTIVES

To evaluate the effectiveness and safety of PEG compared with NGT for adults with swallowing disturbances.

SEARCH METHODS

We searched The Cochrane Library, MEDLINE, EMBASE, and LILACS from inception to January 2014, and contacted the main authors in the subject area. There was no language restriction in the search.

SELECTION CRITERIA

We planned to include randomised controlled trials comparing PEG versus NGT for adults with swallowing disturbances or dysphagia and indications for nutritional support, with any underlying diseases. The primary outcome was intervention failure (e.g. feeding interruption, blocking or leakage of the tube, no adherence to treatment).

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by The Cochrane Collaboration. For dichotomous and continuous variables, we used risk ratio (RR) and mean difference (MD), respectively with the random-effects statistical model and 95% confidence interval (CI). We assumed statistical heterogeneity when I² > 50%.

MAIN RESULTS

We included 11 randomised controlled studies with 735 participants which produced 16 meta-analyses of outcome data. Meta-analysis indicated that the primary outcome of intervention failure, occurred in lower proportion of participants with PEG compared to NGT (RR 0.18, 95% CI 0.05 to 0.59, eight studies, 408 participants, low quality evidence) and this difference was statistically significant. For this outcome, we also subgrouped the studies by endoscopic gastrostomy technique into pull, and push and not reported. We observed a significant difference favouring PEG in the pull subgroup (RR 0.07, 95% CI 0.01 to 0.35, three studies, 90 participants). Thepush subgroup contained only one clinical trial and the result favoured PEG (RR 0.05, 95% CI 0.00 to 0.74, one study, 33 participants) techniques. We found no statistically significant difference in cases where the technique was not reported (RR 0.43, 95% CI 0.13 to 1.44, four studies, 285 participants).There was no statistically significant difference between the groups for meta-analyses of the secondary outcomes of mortality (RR 0.86, 95% CI 0.58 to 1.28, 644 participants, nine studies, very low quality evidence), overall reports of any adverse event at any follow-up time point (ITT analysis, RR 0.83, 95% CI 0.51 to 1.34), 597 participants, 6 studies, moderate quality evidence), specific adverse events including pneumonia (aspiration) (RR 0.70, 95% CI 0.46 to 1.06, 645 participants, seven studies, low quality evidence), or for the meta- analyses of the secondary outcome of nutritional status including weight change from baseline, and mid-arm circumference at endpoint, although there was evidence in favour of PEG for meta-analyses of mid-arm circumference change from baseline (MD 1.16, 95% CI 1.01 to 1.31, 115 participants, two studies), and levels of serum albumin were higher in the PEG group (MD 6.03, 95% CI 2.31 to 9.74, 107 participants).For meta-analyses of the secondary outcomes of time on enteral nutrition, there was no statistically significant difference (MD 14.48, 95% CI -2.74 to 31.71; 119 participants, two studies). For meta-analyses of quality of life measures (EuroQol) outcomes in two studies with 133 participants, for inconvenience (RR 0.03, 95% CI 0.00 to 0.29), discomfort (RR 0.03, 95% CI 0.00 to 0.29), altered body image (RR 0.01, 95% CI 0.00 to 0.18; P = 0.001) and social activities (RR 0.01, 95% CI 0.00 to 0.18) the intervention favoured PEG, that is, fewer participants found the intervention of PEG to be inconvenient, uncomfortable or interfered with social activities. However, there were no significant differences between the groups for pain, ease of learning to use, or the secondary outcome of length of hospital stay (two studies, 381 participants).

AUTHORS' CONCLUSIONS

PEG was associated with a lower probability of intervention failure, suggesting the endoscopic procedure may be more effective and safe compared with NGT. There is no significant difference in mortality rates between comparison groups, or in adverse events, including pneumonia related to aspiration. Future studies should include details of participant demographics including underlying disease, age and gender, and the gastrostomy technique.

[Effects of nasogastric catheterization in patients with stroke and dysphagia]

This study aimed to analyze the effects of gastric intubation in patients with stroke and dysphagia. A systematic literature review was performed in six databases, using the keywords stroke and intubation, gastrointestinal. One hundred and twenty studies were found, from which three clinical trials were selected. The results showed different outcomes, including: increased serum albumin level (gastrostomy), poor prognosis and risk of death (gastrostomy), increased treatment failures because of blocking, displacement and reinsertion need of the nasogastric tube, and increased incidence of gastrointestinal bleeding (nasogastric tube). From the results obtained in this systematic review, we emphasize the following evidences: a nasogastric catheter should be adopted as a method of early enteral feeding; treatment failures are more common in those who use nasogastric tube-feeding; outcomes related to improved functional status of patients were similar, regardless of the method of nutritional therapy used.

Predictors of recovery of functional swallow after gastrostomy tube placement for Dysphagia in stroke patients after inpatient rehabilitation: a pilot study

OBJECTIVE

To determine predictors of early recovery of functional swallow in patients who had gastrostomy (percutaneous endoscopic gastrostomy [PEG]) placement for dysphagia and were discharged to inpatient rehabilitation (IPR) after stroke.

METHODS

A retrospective study of prospectively identified patients with acute ischemic and hemorrhagic stroke from July 2008 to August 2012 was conducted. Patients who had PEG during stroke admission and were discharged to IPR, were studied. We compared demographics, stroke characteristics, severity of dysphagia, stroke admission events and medications in patients who remained PEG-dependent after IPR with those who recovered functional swallow.

RESULTS

Patients who remained PEG dependent were significantly older (73 vs. 54 years, p=0.009). Recovery of swallow was more frequent for hemorrhagic stroke patients (80% vs. 47%, p=0.079). Age, adjusting for side of stroke (odds ratio [OR], 0.89; 95% confidence interval [CI], 0.82-0.98; p=0.016) and left-sided strokes, adjusting for age (OR, 15.15; 95% CI, 1.32-173.34; p=0.028) were significant predictors of swallow recovery. Patients who recovered swallowing by discharge from IPR were more likely to be discharged home compared to those who remained PEG-dependent (90% vs. 42%, p=0.009).

CONCLUSION

Younger age and left-sided stroke may be predictive factors of early recovery of functional swallow in patients who received PEG. Prospective validation is important as avoidance of unnecessary procedures could reduce morbidity and healthcare costs.

Enteral feeding pumps: efficacy, safety, and patient acceptability

Enteral feeding is a long established practice across pediatric and adult populations, to enhance nutritional intake and prevent malnutrition. Despite recognition of the importance of nutrition within the modern health agenda, evaluation of the efficacy of how such feeds are delivered is more limited. The accuracy, safety, and consistency with which enteral feed pump systems dispense nutritional formulae are important determinants of their use and acceptability. Enteral feed pump safety has received increased interest in recent years as enteral pumps are used across hospital and home settings. Four areas of enteral feed pump safety have emerged: the consistent and accurate delivery of formula; the minimization of errors associated with tube misconnection; the impact of continuous feed delivery itself (via an enteral feed pump); and the chemical composition of the casing used in enteral feed pump manufacture. The daily use of pumps in delivery of enteral feeds in a home setting predominantly falls to the hands of parents and caregivers. Their understanding of the use and function of their pump is necessary to ensure appropriate, safe, and accurate delivery of enteral nutrition; their experience with this is important in informing clinicians and manufacturers of the emerging needs and requirements of this diverse patient population. The review highlights current practice and areas of concern and establishes our current knowledge in this field.

Gastroenteric tube feeding: techniques, problems and solutions

Gastroenteric tube feeding plays a major role in the management of patients with poor voluntary intake, chronic neurological or mechanical dysphagia or gut dysfunction, and patients who are critically ill. However, despite the benefits and widespread use of enteral tube feeding, some patients experience complications. This review aims to discuss and compare current knowledge regarding the clinical application of enteral tube feeding, together with associated complications and special aspects. We conducted an extensive literature search on PubMed, Embase and Medline using index terms relating to enteral access, enteral feeding/nutrition, tube feeding, percutaneous endoscopic gastrostomy/jejunostomy, endoscopic nasoenteric tube, nasogastric tube, and refeeding syndrome. The literature showed common routes of enteral access to include nasoenteral tube, gastrostomy and jejunostomy, while complications fall into four major categories: mechanical, e.g., tube blockage or removal; gastrointestinal, e.g., diarrhea; infectious e.g., aspiration pneumonia, tube site infection; and metabolic, e.g., refeeding syndrome, hyperglycemia. Although the type and frequency of complications arising from tube feeding vary considerably according to the chosen access route, gastrointestinal complications are without doubt the most common. Complications associated with enteral tube feeding can be reduced by careful observance of guidelines, including those related to food composition, administration rate, portion size, food temperature and patient supervision.

Long-term nasogastric tube feeding in elderly stroke patients--an assessment of nutritional adequacy and attitudes to gastrostomy feeding in Asians

BACKGROUND

Gastrostomy feeding is superior to long-term nasogastric (NG) feeding in patients with dysphagic stroke, but this practice remains uncommon in Asia. We sought to examine the nutritional adequacy of patients on long term NG feeding and identify barriers to gastrostomy feeding in these patients.

METHODOLOGY

A prospective comparison of subjective global assessment (SGA), and anthropometry (mid-arm muscle circumference, MAMC; triceps skinfold thickness, TST) between elderly stroke patients on long-term NG feeding and matched controls was performed. Selected clinicians and carers of patients were interviewed to assess their knowledge and attitudes to gastrostomy feeding.

RESULTS

140 patients (70 NG, 70 oral) were recruited between September 2010 and February 2011. Nutritional status was poorer in the NG compared to the oral group (SGA grade C 38.6% NG vs 0% oral, p<0.001; TST males 10.7 + 3.7 mm NG vs 15.4 + 4.6 mm oral, p<0.001; MAMCmales 187.9 + 40.4 mm NG vs 228.7 + 31.8 mm oral, p<0.001). 45 (64.3%) patients on long-term NG feeding reported complications, mainly consisting of dislodgement (50.5%), aspiration of feed content (8.6%) and trauma from insertion (4.3%). Among 20 clinicians from relevant speciliaties who were interviewed, only 11 (55%) clinicians would routinely recommend a PEG. All neurologists (100%) would recommend a PEG, whilst the response was mixed among non-neurologists. Among carers, lack of information (47.1%) was the commonest reason stated for not choosing a PEG.

CONCLUSION

Elderly patients with stroke on long term NG feeding have a poor nutritional status. Lack of recommendation by clinicians appears to be a major barrier to PEG feeding in these patients.

Efficacy of nasal bridles in avoiding percutaneous endoscopic gastrostomy placement

OBJECTIVE

The aim of the study was to report the use of nasogastric tube bridles to avoid dislodging of percutaneous endoscopic gastrostomy tubes. Specifically it was intended to see if they reduced feeding time, medical input and costs.

DESIGN

and setting This was a cohort study in a district hospital setting.

PATIENTS

164 patients admitted with conditions causing acutely impaired swallowing.

INTERVENTIONS

140 of 164 patients referred received a NGT bridle.

RESULTS

Of these, 49 (35%) died by 28 days and 68 (48.6%) at 1 year; 73 (52.1%) had regained adequate oral intake at 28 days and 27 (19.2%) had proceeded to PEG. Of those not bridled, nine (37.5%) died by 28 days and 10 (41.7%) at 1 year with the remainder eating. There was no significant difference in mortality between groups. There were no complications attributed to bridles.

CONCLUSION

We conclude that nasogastric bridles are safe and represent an appropriate method to maintain nutrition while seeing if the underlying disease process will stabilise in these critically ill patients. They have the benefits of avoiding unnecessary PEG and the associated complications and cost.

Percutaneous endoscopic gastrostomy versus nasogastric tube feeding for adults with swallowing disturbances

BACKGROUND

A number of conditions compromise the passage of food along the digestive tract. Nasogastric tube (NGT) feeding is a classic, time-proven technique, although its prolonged use can lead to complications such as lesions to the nasal wing, chronic sinusitis, gastro-oesophageal reflux, and aspiration pneumonia. Another method of infusion, percutaneous endoscopy gastrostomy (PEG), is generally used when there is a need for enteral nutrition for a longer time period. There is a high demand for PEG in patients with swallowing disorders, although there is no consistent evidence about its effectiveness and safety as compared to NGT.

OBJECTIVES

To evaluate the effectiveness and safety of PEG as compared to NGT for adults with swallowing disturbances, by updating our previous Cochrane review.

SEARCH METHODS

We searched The Cochrane Library, MEDLINE, EMBASE, and LILACS from inception to September 2011, as well as contacting main authors in the subject area. There was no language restriction in the search.

SELECTION CRITERIA

We planned to include randomised controlled trials comparing PEG versus NGT for adults with swallowing disturbances or dysphagia and indications for nutritional support, with any underlying diseases. The primary outcome was intervention failure (e.g. feeding interruption, blocking or leakage of the tube, no adherence to treatment).

DATA COLLECTION AND ANALYSIS

Review authors performed selection, data extraction and evaluation of methodological quality of studies. For dichotomous and continuous variables, we used risk ratio (RR) and mean difference (MD), respectively with the random-effects statistical model and 95% confidence interval (CI). We assumed statistical heterogeneity when I² > 50%.

MAIN RESULTS

We included nine randomised controlled studies. We did not identify new eligible studies published after our previous review literature search date (August 2009). Intervention failure occurred in 19/156 patients in the PEG group and 63/158 patients in the NGT group (RR 0.24, 95%CI 0.08 to 0.76, P = 0.01) in favour of PEG. There was no statistically significant difference between comparison groups in complications (RR 1.00, 95%CI 0.91 to 1.11, P = 0.93).

AUTHORS' CONCLUSIONS

PEG was associated with a lower probability of intervention failure, suggesting the endoscopic procedure is more effective and safe as compared to NGT. There is no significant difference of mortality rates between comparison groups, and pneumonia irrespective of underlying disease (medical diagnosis). Future studies should include previously planned and executed follow-up periods, the gastrostomy technique, and the experience of the professionals to allow more detailed subgroup analysis.
