Percutaneous endoscopic gastrostomy in a general hospital: prospective evaluation of indications, outcome, and randomised comparison of two tube designs

Is There a Difference in Metabolic Outcome Between Different Enteral Formulas?

BACKGROUND

Despite appropriate enteral nutrition, many elderly patients do not reach a good metabolic outcome. Two nutrition formulas are commonly used in Israel with no evidence-based medicine to indicate preference of one over the other.

METHODS

We describe a 2-month observational study of patients fed by 1 of the 2 formulas. The first (Osmolite, Abbott Company, Abbott Park, IL) is without fiber, and the second (Easy Fiber, Easyline Company Givataim, Israel) in addition to containing fiber is also richer in protein, vitamins, and minerals. The formula was selected by the primary care physician before enrollment in the study and was not influenced by the investigators. Routine blood tests as well as body weight were monitored at the start of enteral feeding and during the 2 months following as part of the regular follow-up.

RESULTS

Fifty-seven patients were fed with the regular formula and 77 with the enriched one. No statistically significant differences were noted between the groups during the follow-up period, in body weight, cholesterol levels, total lymphocyte count, renal function tests, or electrolyte balance. However, in the enriched formula group there was a significant decrease in glucose (p < .05), and increase in albumin (p < .05) and hemoglobin (p = .01) levels.

CONCLUSIONS

Enteral feeding with enriched formula appears to improve albumin and hemoglobin levels as well as diabetic control, thus it may be more appropriate than the nonfiber diet for use in long-term care patients.

Evidence-based guidelines for the management of large hemispheric infarction : a statement for health care professionals from the Neurocritical Care Society and the German Society for Neuro-intensive Care and Emergency Medicine

Large hemispheric infarction (LHI), also known as malignant middle cerebral infarction, is a devastating disease associated with significant disability and mortality. Clinicians and family members are often faced with a paucity of high quality clinical data as they attempt to determine the most appropriate course of treatment for patients with LHI, and current stroke guidelines do not provide a detailed approach regarding the day-to-day management of these complicated patients. To address this need, the Neurocritical Care Society organized an international multidisciplinary consensus conference on the critical care management of LHI. Experts from neurocritical care, neurosurgery, neurology, interventional neuroradiology, and neuroanesthesiology from Europe and North America were recruited based on their publications and expertise. The panel devised a series of clinical questions related to LHI, and assessed the quality of data related to these questions using the Grading of Recommendation Assessment, Development and Evaluation guideline system. They then developed recommendations (denoted as strong or weak) based on the quality of the evidence, as well as the balance of benefits and harms of the studied interventions, the values and preferences of patients, and resource considerations.

Predictors of Percutaneous Endoscopic Gastrostomy Tube Placement after Stroke

Aims:

the goal of this study was to identify important prognostic variables affecting placement of a percutaneous endoscopic gastrostomy (Peg) tube after acute stroke.

Methods:

We retrospectively reviewed our patient database to identify acute ischemic stroke patients who placed Peg or nasogastric tube (Ngt) tube, but were free of other confounding conditions affecting swallowing. A total of 340 patients were involved in our study. We assessed the influence of age, National Institutes of Health stroke scale (NIHss) score, infarct volume, stroke subtype based on the toAst criteria, swallowing disorders, bilateral lesions in cerebrum and length of stay (los) in a logistic regression analysis.

Results:

In univariate analysis, age (p=0.048), NIHss score (p<0.0001), lesion volume (p<0.0001), los (p<0.0001), stroke location (p=0.045), and swallowing disorders (p<0.0001) were found to be the primary predictors of placing Peg. the presence of lesions in bilateral cerebral was included in the final model based on clinical considerations. After multivariate adjustment, only NIHss score (odds ratio [oR], 4.055; 95% confidence interval [CI], 2.398-6.857; p=0.0001), lesion volume (oR, 1.69; 95%CI, 1.09–4.39; p=0.014), swallowing disorders (oR, 1.151; 95% CI, 1.02-1.294; p=0.047), los (oR, 0.955; 95% CI, 0.914-0.998; p=0.0415) and bilateral lesions (oR, 2.8; 95% CI, 1.666-4.705; p=0.0001) remained significant.

Conclusion:

our data shows that NIHss score, lesion volume, swallowing disorders, los and bilateral lesions in cerebrum can predict the requiring of Peg tube insertion in patients after stroke.

Do patients with advanced cognitive impairment admitted to hospitals with higher rates of feeding tube insertion have improved survival?

CONTEXT

Research is conflicting on whether receiving medical care at a hospital with more aggressive treatment patterns improves survival.

OBJECTIVES

The aim of this study was to examine whether nursing home residents admitted to hospitals with more aggressive patterns of feeding tube insertion had improved survival.

METHODS

Using the 1999-2007 Minimum Data Set matched to Medicare claims, we identified hospitalized nursing home residents with advanced cognitive impairment who did not have a feeding tube inserted prior to their hospital admissions. The sample included 56,824 nursing home residents and 1773 acute care hospitals nationwide. Hospitals were categorized into nine groups based on feeding tube insertion rates and whether the rates were increasing, staying the same, or decreasing between the periods of 2000-2003 and 2004-2007. Multivariate logit models were used to examine the association between the hospital patterns of feeding tube insertion and survival among hospitalized nursing home residents with advanced cognitive impairment.

RESULTS

Nearly one in five hospitals (N=366) had persistently high rates of feeding tube insertion. Being admitted to these hospitals with persistently high rates of feeding tube insertion was not associated with improved survival when compared with being admitted to hospitals with persistently low rates of feeding tube insertion. The adjusted odds ratios were 0.93 (95% confidence interval [CI]: 0.87, 1.01) and 1.02 (95% CI: 0.95, 1.09) for one-month and six-month posthospitalization survival, respectively.

CONCLUSION

Hospitals with more aggressive patterns of feeding tube insertion did not have improved survival for hospitalized nursing home residents with advanced cognitive impairment.

Percutaneous endoscopic gastrostomy tube replacement: A simple procedure?

Replacement of gastrostomy tube in patients undergoing percutaneous endoscopic gastrostomy (PEG) is generally considered as a safe and simple procedure. However, it could be associated with serious complications, such as gastrocutaneous tract disruption and intraperitoneal tube placement, which may lead to chemical peritonitis and even death. When PEG tube needs a replacement (e.g., occlusion or breakage of the tube), clinicians must realize that the gastrocutaneous tract of PEG is more friable than that of surgical gastrostomy because there is no suture fixation between gastric wall and abdominal wall in PEG. In general, the tract of PEG begins to mature in 1-2 wk after placement and it is well formed in 4-6 wk. However, this process could take a longer period of time in some patients. Accordingly, this article describes three major principles of a safe PEG tube replacement: (1) good control of the replacement tube along the well-formed gastrocutaneous tract; (2) minimal insertion force during the replacement, and, most importantly; and (3) reliable methods for the confirmation of intragastric tube insertion. In addition, the management of patients with suspected intraperitoneal tube placement (e.g., patients having abdominal pain or signs of peritonitis immediately after PEG tube replacement or shortly after tube feeding was resumed) is discussed. If prompt investigation confirms the intraperitoneal tube placement, surgical intervention is usually required. This article also highlights the fact that each institute should have an optimal protocol for PEG tube replacement to prevent, or to minimize, such serious complications. Meanwhile, clinicians should be aware of these potential complications, particularly if there are any difficulties during the gastrostomy tube replacement.

Interventions for dysphagia and nutritional support in acute and subacute stroke

BACKGROUND

Dysphagia (swallowing problems) are common after stroke and can cause chest infection and malnutrition. Dysphagic, and malnourished, stroke patients have a poorer outcome.

OBJECTIVES

To assess the effectiveness of interventions for the treatment of dysphagia (swallowing therapy), and nutritional and fluid supplementation, in patients with acute and subacute (within six months from onset) stroke.

SEARCH METHODS

We searched the Cochrane Stroke Group Trials Register (February 2012), MEDLINE (1966 to July 2011), EMBASE (1980 to July 2011), CINAHL (1982 to July 2011) and Conference Proceedings Citation Index- Science (CPCI-S) (1990 to July 2011). We also searched the reference lists of relevant trials and review articles, searched Current Controlled Trials and contacted researchers (July 2011). For the previous version of this review we contacted the Royal College of Speech and Language Therapists and equipment manufacturers.

SELECTION CRITERIA

Randomised controlled trials (RCTs) in dysphagic stroke patients, and nutritional supplementation in all stroke patients, where the stroke occurred within six months of enrolment.

DATA COLLECTION AND ANALYSIS

Two review authors independently applied the inclusion criteria, assessed trial quality, and extracted data, and resolved any disagreements through discussion with a third review author. We used random-effects models to calculate odds ratios (OR), 95% confidence intervals (95% CI), and mean differences (MD). The primary outcome was functional outcome (death or dependency, or death or disability) at the end of the trial.

MAIN RESULTS

We included 33 studies involving 6779 participants.Swallowing therapy: acupuncture, drug therapy, neuromuscular electrical stimulation, pharyngeal electrical stimulation, physical stimulation (thermal, tactile), transcranial direct current stimulation, and transcranial magnetic stimulation each had no significant effect on case fatality or combined death or dependency. Dysphagia at end-of-trial was reduced by acupuncture (number of studies (t) = 4, numbers of participants (n) = 256; OR 0.24; 95% CI 0.13 to 0.46; P < 0.0001; I(2) = 0%) and behavioural interventions (t = 5; n = 423; OR 0.52; 95% CI 0.30 to 0.88; P = 0.01; I(2) = 22%). Route of feeding: percutaneous endoscopic gastrostomy (PEG) and nasogastric tube (NGT) feeding did not differ for case fatality or the composite outcome of death or dependency, but PEG was associated with fewer treatment failures (t = 3; n = 72; OR 0.09; 95% CI 0.01 to 0.51; P = 0.007; I(2) = 0%) and gastrointestinal bleeding (t = 1; n = 321; OR 0.25; 95% CI 0.09 to 0.69; P = 0.007), and higher feed delivery (t = 1; n = 30; MD 22.00; 95% CI 16.15 to 27.85; P < 0.00001) and albumin concentration (t = 3; n = 63; MD 4.92 g/L; 95% CI 0.19 to 9.65; P = 0.04; I(2) = 58%). Although looped NGT versus conventional NGT feeding did not differ for end-of-trial case fatality or death or dependency, feed delivery was higher with looped NGT (t = 1; n = 104; MD 18.00%; 95% CI 6.66 to 29.34; P = 0.002). Timing of feeding: there was no difference for case fatality, or death or dependency, with early feeding as compared to late feeding. Fluid supplementation: there was no difference for case fatality, or death or dependency, with fluid supplementation. Nutritional supplementation: there was no difference for case fatality, or death or dependency, with nutritional supplementation. However, nutritional supplementation was associated with reduced pressure sores (t = 2; n = 4125; OR 0.56; 95% CI 0.32 to 0.96; P = 0.03; I(2) = 0%), and, by definition, increased energy intake (t = 3; n = 174; MD 430.18 kcal/day; 95% CI 141.61 to 718.75; P = 0.003; I(2) = 91%) and protein intake (t = 3; n = 174; MD 17.28 g/day; 95% CI 1.99 to 32.56; P = 0.03; I(2) = 92%).

AUTHORS' CONCLUSIONS

There remains insufficient data on the effect of swallowing therapy, feeding, and nutritional and fluid supplementation on functional outcome and death in dysphagic patients with acute or subacute stroke. Behavioural interventions and acupuncture reduced dysphagia, and pharyngeal electrical stimulation reduced pharyngeal transit time. Compared with NGT feeding, PEG reduced treatment failures and gastrointestinal bleeding, and had higher feed delivery and albumin concentration. Nutritional supplementation was associated with reduced pressure sores, and increased energy and protein intake.

Indications, complications and long-term follow-up of patients undergoing percutaneous endoscopic gastrostomy: A retrospective study

INTRODUCTION

Gastroenterology units have faced a major increase in referrals for PEG insertion over the last decade. For this reason we decided to review our PEG insertion procedures with regard to indications, complications and follow-up.

MATERIALS AND METHODS

The indications, success of procedure, complications, long-term results of PEG in patients of Gulhane Military Medical Academy, Haydarpasa Training Hospital between October 2002 and April 2009 were retrospectively evaluated.

RESULTS

81 patients had undergone PEG insertion and follow-up information has been available for 77 patients. 40 were men with the mean age of all patients 70.74 ± 20.82 (range 20 to 104 years). PEG was successfully placed in all patients except in one patient who had gastric bleeding during the procedure. There was only one mortality related with the placement procedure. The most common indication for PEG was neurologic disorders in 71 (92%) patients. Other indications were head and neck cancers in 6 (8%) patients. Median follow-up period was 12 months (range, 3 days to 78 months). PEG related complications were seen in only 14 patients (18.2%) in 16 events with a total complication rate as 21%.

CONCLUSIONS

PEG placement is a safe procedure and well-tolerated with a low mortality and complication rate even in older patients who have multiple co-morbidities under adequate precautions.

Prediction of survival and complications after percutaneous endoscopic gastrostomy in an individual by using clinical factors with an artificial neural network system

BACKGROUND

The demand for percutaneous endoscopic gastrostomy (PEG) has increased because it is safe and a technically easy method, but it has risks of severe complications including death and a high mortality rate within 30 days. At present, we cannot predict survival or the incidence of complications before tube placement in an individual. Earlier studies have used traditional statistical analysis by assuming a linear relationship between clinical features, but most phenomena in the clinical situation are not linearly related.

AIMS

We predicted the survival and complications before PEG placement in an individual by using artificial neural network (ANN) system, which can assess the nonlinear relationship.

METHODS

We studied 100 patients who underwent PEG at the Kitasato Medical Institute Hospital from 1997 to 2005. Clinical data and laboratory data were used as input data. Complications related to PEG placement and survival dates were historically and prospectively measured. From the clinical data and laboratory data, we examined the prediction of outcome in individual patients using multiple logistic regression analysis and an ANN.

RESULTS

The correct answer rate of survival by multiple logistic regression analysis was 67.9%. In contrast, using the ANN, we correctly predicted the survival date and aspiration pneumonia in 75 and 89% of patients, respectively. There was a nonlinear relationship among input factors and survival and complications.

CONCLUSION

We correctly predicted the outcome and complications of individual patients with PEG with a high correct answer rate. Our data show the potential of an ANN as a powerful tool in daily clinical use to individualize treatment ('tailor-made medicine') for PEG and reduce costs.

Resumption of oral intake following percutaneous endoscopic gastrostomy

BACKGROUND AND AIMS

Percutaneous endoscopic gastrostomy (PEG) provides enteral nutrition to patients who cannot swallow. Few studies have prospectively evaluated its long-term outcomes or eventual resumption of oral intake.

METHODS

Consecutive PEG patients were prospectively recruited from a tertiary hospital over 12 months and followed until all had met the primary endpoints of death or resumption of oral diet with PEG extubation. Data was collected by standardised periodic phone interview.

RESULTS

Forty patients (24 males, median age 74 years) were followed for up to 8.4 years (median 5.3 months, interquartile range [IQR] 13.6 months). The end-of-study mortality rate was 70% (median 6.8 months, IQR 19.9 months) and the only predictor of mortality was head injury as the indication for PEG (Cox regression HR 5.90, 95% CI: 1.2-28.4). At two years following PEG, 30% of patients had resumed oral intake (median 2.9 months, IQR 7.2 months) and 19% remained on PEG-feeding. Predictors of resumption of oral intake were the ability to tolerate some oral intake at 3 months (HR: 248.5, 95% CI: 8.7-7065.3) and 6 months (HR: 6.3, 95% CI: 1.03-38.9) but not at 12 months. Cumulative survival was highest for ear nose and throat (ENT) tumour and worst for acute head injury (log rank P = 0.048).

CONCLUSIONS

Half of all PEG patients remained alive at 2 years using PEG or have resumed full oral intake. A supervised trial of oral intake at 3 or 6 months may help predict eventual resumption of per oral diet.

The Prevention and Management of Complications associated with established Percutaneous Gastrostomy Tubes in Adults: A Systematic Review

OBJECTIVE

This systematic review aimed to summarise the best available evidence relating to the prevention and management of complications associated with established percutaneous gastrostomy tubes in adults.

INCLUSION CRITERIA

This review considered studies investigating the effectiveness of strategies to prevent and/or manage complications associated with established percutaneous gastrostomy (PEG) tubes in adults where care was provided in the hospital, aged care or community setting. Complications included PEG stoma site infection, occlusion, site excoriation and inadvertent removal.

SEARCH STRATEGY

The search strategy aimed to find published and unpublished studies and was limited to reports published in the English language. Reference lists of studies that met the inclusion criteria were searched for additional studies. Company representatives were also contacted for information about ongoing or unpublished studies.

METHODOLOGICAL QUALITY

Study reports selected for retrieval were assessed by two independent reviewers for methodological quality prior to inclusion in the review using a critical appraisal instrument developed specifically for this review.

RESULTS

There were 40 studies that met the inclusion criteria for this review. Thirty-five were excluded after critical appraisal. The five remaining studies contained information regarding strategies for the prevention and/or management of site infection, occlusion and inadvertent removal. There were no studies include that addressed excoriation at the stoma site. Reported strategies for the prevention of complications included regular follow-up, the provision of pre discharge instructions and programmed tube changes. Strategies reported for the management of site infection included local antibiotic therapy, skin care and intravenous antibiotic therapy. Reported interventions for the management of occlusion included the use of enzymes, guidewires, flushing, replacement and removal. The only intervention reported for the management of inadvertent removal was replacement.

CONCLUSION

The research regarding the prevention and management of complications associated with PEG tubes is sparse and potentially of poor quality. Interventions are often poorly described and few comparative studies are published. While few recommendations for practice can be made a range of recommendations for future research are provided. There is an urgent need for further research examining many aspects of the prevention and management of complications associated with PEG tubes.

[Techniques and complications in post-interventional and long-term enteral nutrition]

Enteral nutrition in patients is a well established procedure. Percutaneous endoscopic gastrostomy has been widely used to maintain long-term enteral nutrition and has become the method of choice. Under careful observation of indication, contraindication and technique the risk of complication of PEG is reduced drastically. The enteral nutrition via PEG is a step of the multimodal treatment in critically ill patients.

Does percutaneous endoscopic gastrostomy prevent gastro-oesophageal reflux during the enteral feeding of elderly patients?

Percutaneous endoscopic gastrostomy (PEG) is reported to be a safe method for enteral feeding, although its ability to prevent gastro-oesophageal reflux (GOR) during enteral feeding remains controversial. In 12 elderly patients fed enterally to avoid the risk of tracheal aspiration, we have compared two 24-h oesophageal pH profiles, one recorded when enteral feeding was delivered at first via a nasogastric tube (NGT), and the other via a PEG. The second recording was always performed at least 8 days after gastrostomy placement. Enteral nutrition consisted of 500 ml of a polymeric diet delivered 3 times a day at 08:00, 13:00 and 18:00. After gastrostomy placement, enteral feeding was associated with a pathological acid reflux in 8 out of 12 patients. In all of these 8 patients, GOR was mostly related to a high number of reflux episodes. In 4 out of 8 patients, GOR occurred only during the 3 h following the administration of the nutritive diet. In 4 of the patients, GOR did not occur any more after removal of the NGT, whilst gastrostomy placement was followed by GOR in 5 patients. GOR during enteral feeding via PEG is common in elderly subjects. We have shown that a chronological relationship existed in some patients between the endoscopic procedure and the onset of a pathological GOR.

ESPEN Guidelines on Enteral Nutrition: Geriatrics

Nutritional intake is often compromised in elderly, multimorbid patients. Enteral nutrition (EN) by means of oral nutritional supplements (ONS) and tube feeding (TF) offers the possibility to increase or to insure nutrient intake in case of insufficient oral food intake. The present guideline is intended to give evidence-based recommendations for the use of ONS and TF in geriatric patients. It was developed by an interdisciplinary expert group in accordance with officially accepted standards and is based on all relevant publications since 1985. The guideline was discussed and accepted in a consensus conference. EN by means of ONS is recommended for geriatric patients at nutritional risk, in case of multimorbidity and frailty, and following orthopaedic-surgical procedures. In elderly people at risk of undernutrition ONS improve nutritional status and reduce mortality. After orthopaedic-surgery ONS reduce unfavourable outcome. TF is clearly indicated in patients with neurologic dysphagia. In contrast, TF is not indicated in final disease states, including final dementia, and in order to facilitate patient care. Altogether, it is strongly recommended not to wait until severe undernutrition has developed, but to start EN therapy early, as soon as a nutritional risk becomes apparent.

Dwell time and functional failure in percutaneous endoscopic gastrostomy tubes: a prospective randomized-controlled comparison between silicon polymer and polyurethane percutaneous endoscopic gastrostomy tubes

BACKGROUND

Silicone percutaneous endoscopic gastros-tomy (PEG) tubes are associated with more short-term complications and possibly fail sooner than those made of polyurethane. Understanding the deterioration and long-term complications leading to tube failure has important clinical and cost implications.

AIM

To compare dwell time and patterns of failure ofsilicone polymer and polyurethane PEG tubes.

METHODS

Participants randomized to receive a siliconepolymer (n = 76) or polyurethane (n = 62) PEG werevisited monthly for 540 days, until death or tube removal. Tube and exit site characteristics and reasons for removal were recorded.

RESULTS

Tube failure occurred in 25% of silicone PEGs and 12.9% of polyurethane PEGs. Mean tube survival for silicone PEGs was 377.2 days (CI: 326-428) and for polyurethane 436.8 days (CI: 383-490; P = 0.13). A greater proportion of silicone PEGs developed intralumenal colonization and altered tube integrity than polyurethane (P < 0.001). Silicone PEGs blocked more frequently (P < 0.005) and were removed because of irreversible blockage more often than polyurethane PEGs (P < 0.05). Silicone PEGs with reversible blockage and tube integrity changes had a significantly greater probability of failure than silicone tubes without these changes (P < 0.005 and P < 0.05, respectively).

CONCLUSIONS

Observations over time indicate that sili-cone PEGs are more susceptible than polyurethane PEGs to tube deterioration, resulting in substantially increased management demands to sustain patients' feeding and medication schedules.

Mediastinitis complicating a percutaneous endoscopic gastrostomy: a case report

BACKGROUND

Since its introduction in the early 1980s, percutaneous endoscopic gastrostomy has become the most popular method for performing a gastrostomy for long-term enteral feeding. It has been associated, however, with a lot of minor and major complications.

CASE PRESENTATION

A case of mediastinitis with concominant sepsis caused by a masked esophageal perforation after percutaneous endoscopic gastrostomy in a multi-traumatized, brain-injured patient is presented. Ten - fourteen days after the procedure, the patient became febrile and gradually septic with tenderness of the sternum and upper abdomen. Computerized tomography of the thorax revealed mediastinitis. An urgent left thoracotomy and laparotomy were performed for drainage of the mediastinum, removal of the gastrostomy and insertion of a jejunostomy tube. The patient improved soon after the surgery. He was successfully weaned off the ventilator and was discharged from the Intensive Care Unit.

CONCLUSION

Perforating mediastinitis is a rare but potentially lethal complication of percutaneous endoscopic gastrostomy. When diagnosed and properly treated it may have a favourable outcome.

An assessment of open access referral for percutaneous endoscopic gastrostomy in a district general hospital

OBJECTIVE

To determine the indications, technical success and outcomes of open access percutaneous endoscopic gastrostomy (PEG) insertion in the district general hospital setting.

DESIGN

This study was a retrospective audit of patients receiving PEG by the thread pull method from November 1998 to November 1999, followed by a prospective audit of patients receiving PEG from December 1999 to May 2000. Prophylactic antibiotics were not used. Patient data were collected using a computerized endoscopy unit record system. Clinical assessment was performed and case notes were reviewed. Whenever necessary, telephone follow-up of patients in the community was performed.

PARTICIPANTS

Sixty-five consecutive, unselected patients underwent PEG and 64 were followed up for a total of 7799 patient days. Fifty-seven of 64 (89%) were in-patients. The median age of the patients was 74 years (range, 26-95 years).

MAIN OUTCOME MEASURES

Indications, technical success, early complications and long-term outcomes of PEG.

RESULTS

Cerebrovascular disease was the most common indication for PEG (35/64 (55%)). Technical success was achieved in 62/64 (97%) patients. No serious complications from the procedure were reported: PEG site infection was rare (1/64). Pneumonia was uncommon (8/64 (12.5%)). There were eight (12.5%) deaths during the first week after PEG insertion and 18/64 (28%) during the first month. Mortality at 1 year was 36/64 (56%). Ten of 64 patients (16%) recovered to PEG removal; 18 (28%) continue to be fed via PEG.

CONCLUSION

This audit demonstrates that referral patterns, technical success and long-term outcome of open access referral for PEG in a district general hospital setting are consistent with published series from specialist and tertiary referral centres.

Role of endoscopy in enteral feeding

This is one of a series of statements discussing the utilization of gastrointestinal endoscopy in common clinical situations. The Standards of Practice Committee of the American Society for Gastrointestinal Endoscopy prepared this text. A previous guideline related to this topic (ASGE Publication No. 1017, Gastrointest Endosc 1998;48:699-701). Since that time, new information has become available that requires an update of this statement and its recommendations. In preparing this update, a MEDLINE literature search was performed, and additional references were obtained from the bibliographies of the identified articles and from the recommendations of expert consultants. When inadequate data existed from well-designed prospective trials, emphasis was given to results from large series and reports from recognized experts. Guidelines for appropriate utilization of endoscopy are based on a critical review of the available data and expert consensus. Controlled clinical studies are needed to clarify aspects of this statement, and revision may be necessary as new data appear. Clinical consideration may justify a course of action at variance from these recommendations.

Percutaneous endoscopic gastrostomy and gastrojejunostomy in psychomotor retarded subjects: a follow-up covering 106 patient years

BACKGROUND

Whether psychomotor retarded persons should be treated by percutaneous endoscopic gastrostomy (PEG) or by surgical gastrostomy combined with an antireflux procedure is controversial. Therefore, the authors investigated the feasibility of a PEG and enteral feeding in these patients.

METHODS

Patients referred from specialized institutions for a PEG placement were assessed extensively by a multidisciplinary team. When considered eligible, age and general condition determined the choice of treatment under general anesthesia (group 1) or conscious sedation (group 2). Patients were followed up after 1 and 7 days, 4 and 12 weeks, and thereafter every 6 to 12 weeks. Data were collected prospectively over a period of 5 years until gastrostomy removal, death, or arrival at the censory date, 6 months after PEG placement. The endpoints were 1) to evaluate the procedure and its complications; 2) to discover barriers that impeded adequate nutrition; and 3) to explore the appropriateness of the choice of PEG or percutaneous endoscopic gastrojejunostomy (PEJ).

RESULTS

The procedure was successful in 95% of patients, in every patient in group 1 (35/35; median age, 4.1 years) and in 20 of 23 patients (87%) in group 2 (median age, 22.0 years). There were no procedure-related deaths and no 30-day mortality. Major complications changed from procedure-related problems in the short term (5.4%) to tube-related problems in the long-term (24.1%). Nausea and vomiting interfered with adequate feeding mainly in young children, but dietary adjustments alleviated the symptoms and ensured an adequate intake. The choice of a PEG was incorrect in four patients: surgery was needed twice and two PEGs had to be converted into a PEJ. All seven primarily indicated PEJs seemed justified and of temporary need in five.

CONCLUSIONS

In severely disabled patients, a PEG and adequate enteral nutrition is feasible in the setting of a multidisciplinary approach and protocol-wise follow-up. Yet, anatomic deformities and restricted pulmonary function rendered the procedure more difficult. In cases with obvious aspiration or gastroesophageal reflux, a PEJ combined with acid suppression and prokinetic drugs may be tried before surgery.

Outcome of patients treated with home enteral nutrition

BACKGROUND

The aims of this study were to prospectively analyze the 1-month mortality and long-term outcome of home enteral nutrition (HEN) patients in order to determine the benefits of this treatment.

METHODS

Between 1990 and 1996, 417 patients, aged 64 +/- 25 years, were discharged on HEN and followed up until December 31, 1998, when outcome was assessed, which allowed us to determine survival probabilities and conditions associated with survival.

RESULTS

The mean duration of HEN was 242 +/- 494 days, with a 24- to 103-month follow-up. Probabilities of being alive at 1 month, 1 year, and 5 years were 80%, 41.7%, and 25%, respectively. Factors associated with death were dementia, neurologic disease, head and neck cancer, AIDS, and age over 70 years. A total of 5.5% of patients remained dependent on HEN, 32.6% resumed full oral nutrition, 20.2% of patients died during the first month on HEN, and 35% died after more than 1 month on HEN (219 +/- 257 days). A total of 6.7% of patients stopped HEN for other reasons.

CONCLUSIONS

HEN provides well-tolerated long-term nutritional support in many patients. However, because of their likelihood of being old and the nature of the underlying disease, these patients as a group tend to have a modest prognosis. This calls for the determination of more accurate selection criteria, and the measurement of the impact of HEN on quality of life.

Home enteral tube feeding following cerebrovascular accident

BACKGROUND AND AIMS

In the UK, cerebrovascular accident (CVA) is the third commonest cause of death and the commonest diagnosis in patients receiving home enteral feeding (HETF). This study aimed to use data from the British Artificial Nutrition Survey (BANS) collected between 1996 and 1999 to assess the outcome of patients on HETF, including mortality, return to oral feeding, level of physical activity, and level of dependency, which has resource implications.

RESULTS

it is estimated that about 1.7% of all patients suffering a CVA in the UK between 1996 and 1999 received HETF. At one year, 29.6% died while receiving HETF and another 13% returned to oral feeding. Mortality increased with age and was twice as high in those managed in nursing homes compared to those in their own homes. The patients receiving tube feeding spent only 0.6% of their time in hospital. A total of 43.9% of patients were bed-bound at home (1.9% unconscious) and an additional 30.3% were house-bound. Only 21.2% were independent, and the majority were totally dependent on their carers. In CVA patients on HETF the level of dependency was greater than for those with all types of diagnoses (n=12,997).

CONCLUSION

This study has described the outcome of a large number of patients receiving HETF in the UK. Since patients spent less than 1% of their time in hospital, HETF relieves pressure on the expensive hospital environment, but places more demands on the carers, who have to deal with severely disabled patients. Recovery of swallowing function should be assessed intermittently to prevent unnecessary HETF.

Survival after percutaneous endoscopic gastrostomy placement in older persons

BACKGROUND

The prolongation of life is an important consideration in the decision to initiate long-term tube feeding. This report critically synthesizes the evidence regarding the impact of percutaneous endoscopic gastrostomy (PEG) tube placement on survival in older persons.

METHODS

A systematic search was conducted using MEDLINE from January 1980 until January 1999. Articles reporting survival data in older persons (mean or median age >65 years) after PEG tube placement were identified. The number and age of subjects, length of follow-up, setting, and survival data were extracted from all eligible studies. Mortality data at 1, 2, 6, and 12 months after PEG placement were quantitatively synthesized. Clinical characteristics associated with decreased survival among subjects with PEG tubes were identified.

RESULTS

Five cohort studies compared survival in patients with and without feeding tubes in nursing homes, but none demonstrated a survival benefit. Another cohort study reported increased survival for tube-fed patients with amyotrophic lateral sclerosis. The pooled proportion of all subjects surviving after PEG placement was as follows: 1 month = 0.81 (95% confidence interval [CI], 0.74-0.88), 2 months = 0.70 (95% CI, 0.65-0.74), 6 months = 0.56 (95% CI, 0.20-0.92), and 12 months = 0.38 (95% CI, 0.26-0.49). Advanced age and malignancy were the factors most often reported to be associated with poorer survival among subjects with PEG tubes.

CONCLUSIONS

The impact of PEG placement on survival is not known because the level of evidence is limited. PEG tubes may prolong life in selected populations. However, the majority of older patients selected for PEG placement will not survive 1 year after the procedure. Certain factors may identify those patients more likely to derive a survival benefit from long-term tube feeding. This information may offer some guidance to decision makers for whom prolongation of life is an important factor in the tube-feeding decision.

Tube feeding in nursing home residents with severe and irreversible cognitive impairment

OBJECTIVES

This study was undertaken to determine the degree to which selected demographic and clinical variables are associated with the use of feeding tubes in older nursing home residents with very severe and irreversible cognitive impairment.

DESIGN

Descriptive, cross-sectional, population-based study.

SETTING

Kansas nursing homes from January 1, 1994, through June 30, 1998.

PARTICIPANTS

A total of 4,997 nursing home residents with very severe and irreversible cognitive impairment comprised the study population. Subjects were identified using data in Minimum Data Set (MDS) reports. Those who were included in the study population were over the age of 65, had two consecutive Cognitive Performance Scale scores of 6, were without evidence of significant subsequent improvement, and were not comatose.

MEASUREMENTS

The MDS data on each resident were examined to determine subjects' age, ethnicity, gender, Medicaid eligibility, disease diagnoses, physical functioning, and oral/nutritional status, including feeding tube status. The MDS was also used to determine urban versus rural location of the nursing home. The association between the use of feeding tubes and selected demographic and clinical characteristics was then examined using bivariate and logistic regression tests.

RESULTS

Of the 4,997 residents in the study population, 577 (11.6%) had feeding tubes. In multivariate analysis, feeding tube use was found to be associated with swallowing problems (odds ratio (OR) 5.4, 95% confidence interval (CI) 4.3-6.8); urban location of nursing home (OR 2.9, 95% CI 2.3-3.5); non-white race (OR 2.7, 95% CI 1.9-3.6); stroke (OR 2.5, 95% CI 2.0-3.1); and absence of dementia (OR 2.5, 95% CI 2.0-3.1). Feeding tubes were also more weakly associated with age <86 years, male gender, dependency for all activities of daily living, and absence of a living will. Feeding tube use was not found to be associated with chewing problems, Medicaid status, or resuscitation status.

CONCLUSIONS

Clinical variables including swallowing problems, stroke, and absence of dementia were strongly associated with the use of feeding tubes in this cross-sectional, population-based study. In addition, urban location of nursing home and non-white race were significantly associated with feeding tubes. These findings suggest that feeding tube decisions are strongly influenced by nonclinical factors and invite further investigation.

Day-case percutaneous endoscopic gastrostomy: a viable proposition?

The aim of our study was to evaluate the success rate, complications, and long term outcomes following day-case percutaneous endoscopic gastrostomy (PEG). This retrospective study was carried out in a 650-bed District General hospital in Northamptonshire, UK. Thirty-six patients, aged 28-90 years, were included in the study, 21 males (58%) and 15 females (42%). Indications for PEG insertion included head and neck cancer, dysphagia as a result of primary disease, and AIDS-related malnutrition. Data were collected from the medical and dietetic records. The PEG procedure was successful in 33 patients (92%). In 32 cases (97%) the patient was discharged home. Twenty five of the patients (76%) suffered no complications whilst seven (21%) suffered complications within a month of the procedure. No patient required further surgical intervention. Five patients (15%) died of their primary disease within a month of the procedure. Patients had had their PEG tubes in situ for up to 2.5 years at the end of data collection. We conclude that PEG can be performed as a day-case procedure in stable patients with no increase in complication rate, morbidity, or mortality.

Percutaneous endoscopic gastrostomy and gastrojejunostomy: a critical reappraisal of patient selection, tube function and the feasibility of nutritional support during extended follow-up

BACKGROUND

Percutaneous endoscopic gastrostomy (PEG) is a generally accepted procedure, but the appropriateness of patient selection and the justification of jejunal feeding have not been systematically investigated. Also, a critical appraisal of the applicability and tolerance of nutritional support in the immediate postinsertion period and during prolonged outpatient care is lacking.

METHODS

Prospectively collected data in adult and pediatric patients during a period of 7 years were analyzed. Follow-up data were available at days 1, 7 and 28 and thereafter every 6 to 12 weeks until gastrostomy removal, death or the conclusion of the study.

RESULTS

A PEG was successfully positioned in 268 of the 286 referred patients (94%). A jejunal tube through the PEG (JETPEG) was placed beyond the duodenojejunal ligament in 38 patients. Procedure-related mortality was 1%, 30-day outpatient mortality 6.7%. Total follow-up was 295 patient-years with an overall mortality of 53% (PEG 53%; JETPEG 50%). Both major (8.4%) and minor (24.0%) procedure-related complications in the first 28 days consisted merely of (infectious) wound problems. In prolonged follow-up, the complications were more tube-related. The durability of the tube in surviving patients with a PEG or JETPEG in situ was a median of 495 days (range 162 to 1732 days). Tube dysfunction because of clogging, porosity and fracture occurred after a median of 347 days (range 9 to 1123 days). Nausea, vomiting, bloating and dumping interfered with feeding during the first week and during extended follow-up. Intrajejunal feeding was associated with dumping and diarrhea. In retrospect, the anticipated need of 4 weeks of enteral nutrition was not met in 9.0%. The extension of a PEG into a JETPEG was thought inappropriate in 23.7%. In the remainder, a 91% reduction in aspiration justified its use. The tube life span was equal to or greater than that of a PEG, despite tube dysfunction in 26.8%.

CONCLUSIONS

Proper selection of patients for a PEG, i.e., those with an anticipated need of greater than 4 weeks of enteral nutrition, is a challenge. Notwithstanding an increased rate of tube dysfunction, well-selected patients may benefit from a JETPEG. Follow-up is mandatory because many patients might have become malnourished or underfed while on tube feeding, mainly because of GI intolerance.

Survival after percutaneous endoscopic gastrostomy among older residents of Quebec

CONTEXT

Percutaneous endoscopic gastrostomy has become a mainstay of nutritional support for individuals with swallowing dysfunction. There is little population-based data to guide the use of this intervention in older individuals.

OBJECTIVE

To describe the use of percutaneous endoscopic gastrostomy among older residents of Quebec and to evaluate patient characteristics associated with subsequent survival and hospital discharge.

DESIGN

A population-based cohort study.

SETTING

Quebec, Canada.

PATIENTS

175 individuals with a billing claim for percutaneous endoscopic gastrostomy performed in 1993.

MEASUREMENTS

Billing and hospitalization databases were used to collect patient characteristics, medical diagnoses, discharge destinations, and dates of death. The relationships between demographic and diagnostic variables before gastrostomy, and subsequent survival and discharge home, were evaluated using survival analysis.

RESULTS

Median survival after gastrostomy was 210 days. Mortality at 30 days was 18.3%. Decreased survival was associated with a previous diagnosis of malignancy (risk ratio (RR) = 1.71; 95% CI, 1.09-2.68); mortality did not increase with increasing age. Of 163 individuals hospitalized at the time of gastrostomy, 42 (26%) were discharged home. Individuals with a previous diagnosis of stroke (RR = 2.80; 95% CI 1.01-7.77) were more likely to be discharged home than other individuals.

CONCLUSIONS

Survival after percutaneous endoscopic gastrostomy is poor; the requirement for such a procedure appears to be a marker for severe underlying disease. The greater likelihood of return home after gastrostomy among individuals with stroke suggests that the use of this intervention as an adjunct to rehabilitation is appropriate in these individuals.

Enteral long-term nutrition via percutaneous endoscopic gastrostomy (PEG) in 210 patients: a four-year prospective study

After PEG placement at the Medical Department of the University Hospital in Kiel, 210 patients (mean age 61.3 years; 137 men, 73 women) were prospectively followed-up for 133+/-181 days. Close-meshed evaluations of the development of nutritional status, long-term outcome, complications, subjective acceptability, patient care after discharge from the hospital, survival, and nutritional long-term problems were performed. The PEG procedure (duration 13.3+/-4.2 min) was carried out for neurological (42%), ear-nose-throat (28%), and internal medical (30%) indications. Procedure-related mortality was 0%, while altogether 3.8% severe and 20.0% mild complications were observed. Body weight decreased by a mean of 11.4+/-1.5 kg in the three months before and increased by 3.5+/-1.7 kg one year after PEG placement with no significant differences between malignant or benign underlying diseases. Individual subjective acceptability was excellent in 83%, sufficient in 15%, and poor in 2% of patients only. One-year survival rate was 34.3%. The various results of the present prospective study demonstrate that long-term enteral feeding via PEG is a safe, effective, easy-to-practice, and highly acceptable method with excellent long-term results and distinct improvement of nutritional status. Individual decisions for PEG placement should be considered much earlier and more frequently in appropriate patients.

Percutaneous endoscopic gastrostomy for nutrition support in pregnancy associated with hyperemesis gravidarum and anorexia nervosa

BACKGROUND

Pregnant women with hyperemesis gravidarum (HEG) or anorexia nervosa are at high risk of developing malnutrition and adverse fetal outcome. Providing adequate nutrition support is the mainstay of therapy in these patients. Because of potential complications associated with total parenteral nutrition (TPN), enteral nutrition support is the preferred route.

METHODS

We describe the first two reported cases of percutaneous endoscopic gastrostomy (PEG) placement in two conscious pregnant women who could not tolerate oral feedings because of severe anorexia nervosa and HEG, respectively.

RESULTS

PEG was placed safely and provided adequate enteral nutrition in both patients, resulting in favorable maternal and fetal outcomes.

CONCLUSIONS

Our observation is the first demonstration that PEG may be a safe and effective alternative to TPN in selected pregnant women with HEG or anorexia nervosa who have failed conventional treatment.

Enteral nutrition by percutaneous endoscopic gastrojejunostomy in severe hyperemesis gravidarum: a report of two cases

We describe the first two cases in which percutaneous endoscopic gastrojejunostomy was used as a means to provide enteral nutrition in severe hypermesis gravidarum. The use of this method of enteral access provided an alternative to parenteral nutrition, was well tolerated, cost-effective and had no major complications. In both cases the nutritional goal for mothers as well as appropriate fetal growth and development were achieved.

Enteral feeding: an overview of indications and techniques

Most patients requiring nutritional support can be successfully managed using enteral feeding, i.e. the provision of nutritional support via the gastrointestinal tract. Various routes of access are available and patients should be assessed on an individual basis by the multidisciplinary team to select the most appropriate method and decide on a suitable regimen. Careful management and regular monitoring of enteral feeding are required in order to ensure safe and cost-effective nutritional support; the use of standard protocols and guidelines is recommended. With appropriate training, monitoring and support, enteral feeding is best provided in the community for many patients, and the use of home enteral feeding is rapidly increasing.

Decision-making and outcomes for percutaneous endoscopic gastrostomy: a pilot study

We undertook a retrospective review of 25 patients who had undergone percutaneous endoscopic gastrostomy (PEG). Data regarding the clinical courses were collected, and a questionnaire was administered to patients when possible; in most cases the individual responsible for care answered questions. We pinpointed concerns relevant to the decision-making process. In a substantial proportion of cases, the clinical courses subsequent to PEG were poor. Of 21 surrogates interviewed, 33% were uncertain that proceeding to nutritional support via PEG had been the right decision. Findings indicate a need to improve the process by which decisions to treat by PEG are made, ideally including better prognostic information.

Serum albumin is predictive of 30-day survival after percutaneous endoscopic gastrostomy

BACKGROUND

Percutaneous endoscopic gastrostomy (PEG) tubes have been used since 1980 in patients who require prolonged enteral feeding.

PURPOSE

To identify factors associated with poor survival (defined as survival < 30 days) post-PEG.

METHODS

We assessed a cohort of 64 patients consecutively referred for a percutaneous endoscopic gastrostomy tube in a single, tertiary care hospital. Prior to PEG tube placement, we evaluated relevant clinical variables in each patient to determine their effect on 30-day mortality.

RESULTS

Of the cohort, 43 of 64 (67.2%) survived at least 30 days after tube placement. One death was attributable to tube placement. Bivariate analyses showed that 30-day survival correlated directly with serum albumin (r = .253; p = .049) and inversely with creatinine (r = -0.255; p = .042). Using multivariable logistic regression analysis, only albumin was identified as an independent predictor of 30-day survival (p = .044). Eighty-three percent of patients with a serum albumin > or = 3.0 g/dL survived 30 days compared with 58% with an albumin < 3.0, a difference of 25% (95% CI, -2% to 54%; p = .07).

CONCLUSIONS

In conclusion, serum albumin appears to be a predictor of early survival in individuals undergoing percutaneous endoscopic gastrostomy tube placement.

Complications following percutaneous endoscopic gastrostomy and subsequent catheter replacement in children and young adults

BACKGROUND

Percutaneous endoscopic gastrostomy has gained wide acceptance for patients who require prolonged tube feeding support. We sought to identify complications and associated risk factors of endoscopic gastrostomy and subsequent catheter replacement in pediatric patients.

METHODS

Medical records were reviewed for 137 patients. Odds ratios were calculated for complications related to patient age, weight, weight-for-age Z score, and principal diagnosis.

RESULTS

Seventeen patients (12.4%) developed significant complications after gastrostomy: cellulitis occurred in 10 patients (7.3%); other complications included gastrocolic fistula (2), duodenal hematoma (1), complicated pneumoperitoneum (1), necrotizing fasciitis (1), gastric perforation (1), and catheter migration (1). Patients with cancer had significantly greater odds for developing a wound infection, and patients with AIDS had significantly greater odds for total complications. A trend toward increased wound infection was observed in patients with cardiac disease. Age, weight, and weight-for-age Z score were not associated with adverse outcome. Two complications occurred in 85 patients (2.4%) after gastrostomy catheter replacement.

CONCLUSIONS

Pediatric patients with cancer and AIDS are at increased risk for complications after endoscopic gastrostomy regardless of age, weight, or nutritional status. Infrequent yet life-threatening complications may occur after replacement of initial gastrostomy catheter.

Percutaneous endoscopic gastrostomy in the elderly: complications (review)

Due to varying disease processes, the elderly may have limited oral access to their otherwise intact gastrointestinal tract. In such individuals, the intact gastrointestinal tract must be accessed in other ways. Until the early 1980s, choices were limited to temporary solutions such as the nasogastric tube or to long operative procedures such as the operative gastrostomy tube. The introduction of percutaneous endoscopic gastrostomy (PEG) allowed a quick, safe, and cheap procedure as an option. While PEG tubes have been used to help many of the elderly with their nutritional needs, they are not without risks. Below is a review of the literature concerning PEG complications in the elderly.

Nursing management of patients receiving gastrostomy feeding

A feeding gastrostomy should be considered for patients who require enteral tube feeding for more than 2 weeks. This article describes three types of gastrostomy: percutaneous endoscopic gastrostomy; replacement/surgically placed gastrostomy; and skin level/button gastrostomy. The choice of tube and method of insertion are governed by the patient's clinical condition and lifestyle. General guidelines on the decision to initiate gastrostomy feeding are given, together with indications, insertion and nursing management for each tube.
