Percutaneous endoscopic gastrostomy.

From March 87 to March 92, fifty eight patients were referred to our department for percutaneous endoscopic gastrostomy (PEG). The modality of the feeding tube insertion is described. The most common indications for placement were neurologic disorders in 62% of the cases (n = 36) and malignant diseases in 32% (n = 19). The success rate of the technique was 98.3% (n = 57). No procedure-related mortality was observed. A low rate of major complication (1.7%) and minor complication (10.5%) was noted. Feeding tubes were removed in 21% of patients (n = 12); none of them with malignant disease. Survival curve analysis demonstrated that 50% of patients died within 3 months of PEG placement. Such results raise questions about the selection of patients undergoing PEG. Our experience of patients undergoing PEG. Our experience suggests that PEG is easy and safe, even in debilitated patients, having an acceptable life expectancy.     

Percutaneous endoscopic gastrostomy (PEG): A critical appraisal

Percutaneous endoscopic gastrostomy (PEG) can quickly, reliably, and safely establish enteral feedings for a wide variety of indications. Morbidity associated with PEG is less than conventional surgical gastrostomy, and no mortality has been reported to date. PEG can be performed safely at the bedside, if needed. Moreover, there is no period of gastric atony, and feedings can be initiated after 1 day. PEG is contraindicated in patients with altered hemostasis or mechanical barriers to apposing the stomach to the anterior abdominal wall. Routine broad spectrum antibiotic prophylaxis may limit procedure-related cellulitis and pneumonia.     

Percutaneous endoscopic gastrostomy (PEG). A new procedure comes of age

Our cumulative literature review suggests PEG is a simple, relatively safe, and cost-effective means of establishing enteral access for patients who qualify for long-term nutritional support. Tube placement can be achieved in 98% of patients, usually within 15 to 30 minutes without general anesthesia. The gastrostomy catheter can be easily removed when treatment is ended and conveniently replaced if accidentally dislodged. Complications occur in approximately 17% of patients, but only 3.0% are regarded as serious. No procedure-related deaths have been reported. PEG as the initial choice for feeding tube placement followed by surgical gastrostomy in patients in whom PEG is unsuccessful is a reasonable approach to nutritional management in appropriate patients. PEG for purposes of chronic gastrointestinal decompression and internalization of biliary drainage holds promise but requires further evaluation.     

Percutaneous endoscopic gastrostomy (PEG) for enteral nutrition in patients with stroke

BACKGROUND: The use of percutaneous endoscopic gastrostomy (PEG) for enteral nutrition in patients admitted for stroke is difficult, varying and needs specific consideration. There is therefore need for more data on this patient group. We examined the indications, survival, tube removal and time with PEG in stroke patients and in other patients with PEG with the aim of providing guidance for the management of enteral nutrition via PEG in stroke patients. METHODS: Retrospective assessment of data from all stroke patients and patients with other diseases (control group) who had received PEG for enteral nutrition during a period of 8.5 years. RESULTS: Eighty-three stroke patients with dysphagia received PEG after unsuccessful use of nasogastric tubes or long-term tube feeding. Early mortality rate was 19% in the stroke group, 26% in the older group (>74 years) and 12% in the younger group (60-74 years). The PEG tubes were later removed due to swallowing recovery in 20% of the older group and in 31% of the younger group. At 90 days, 50%-60% still needed PEG. The stroke patients were older compared to the control group (n = 115); 30-day mortality was similar but more patients recovered the ability to swallow. CONCLUSIONS: Stroke patients are older than other patients who receive PEG; 27% have swallowing recovery and more than 75% have long-term need for PEG. Nasogastric tubes often fail, and the need for early PEG placement (within 2 weeks) must be assessed in appropriate patients. The patient's prognosis, the objective of nutritional treatment, duration of dysphagia, age and comorbidity should all be taken into consideration.     

Decision-making for percutaneous endoscopic gastrostomy among older adults in a community setting.

OBJECTIVE: To describe clinical decision-making for percutaneous endoscopic gastrostomy from the perspective of patients, caregivers, and physicians. DESIGN: A prospective cohort study. SETTING AND PATIENTS: All patients aged 60 and older receiving percutaneous endoscopic gastrostomies in a defined community over a 16-month period. MAIN OUTCOMES MEASURES: Either patients or their surrogate decision-makers completed a semistructured face-to-face interview to map out the information gathering process, expectations, and discussants involved in the decision to proceed with gastrostomy feeding. Physicians completed a written questionnaire to determine their likelihood of recommending percutaneous endoscopic gastrostomy, their involvement in the decision-making and recommendation process, and sources of perceived pressure in the decision-making. RESULTS: We identified 100 patients who received percutaneous endoscopic gastrostomy during the study window and 82 primary care physicians who provided care in the defined community. The most common reasons for the procedure were stroke, neurologic disease, and cancer. Patients or their surrogate decision-makers reported multiple discussants, incomplete information, and considerable distress in arriving at the decision to proceed with artificial feeding. This distress was usually in the context of an acute and debilitating illness that often overshadowed the decision about artificial feeding. The decision for gastrostomy often appeared to be a "non-decision" in the sense that decision-makers perceived few alternatives. Physicians also reported considerable distress in arriving at recommendations to proceed with percutaneous endoscopic gastrostomy, including perceived pressures from families or other healthcare professionals. Physicians have clear patterns of triage for percutaneous endoscopic gastrostomy, but the assumptions underlying these patterns are not well supported by the medical literature. CONCLUSIONS: Patients, caregivers, and physicians are often compelled to make decisions about long-term enteral feeding under tragic circumstances and with incomplete information. Decision-makers typically do not perceive any acceptable alternatives. Because data on these patients' long-term functional outcomes are lacking, decision-makers appear to focus primarily on the short-term safety of the procedure and the potential for improved nutrition.     

经皮内镜下胃造瘘术应用进展

经皮内镜下胃造瘘术(PEG)是20世纪80年代开始应用于临床的一种新的内镜介入技术,主要用于胃肠减压和肠内营养,在国外已广泛应用。此文就其方法、适应症、并发症及禁忌症等作一综述。     

Percutaneous endoscopic gastrostomy tube replacement

Percutaneous endoscopic gastrostomy (PEG) is undertaken in order to provide long-term nutrition in patients with dysphagia. Over time, the PEG tubes will deteriorate and will need to be replaced. We describe a method of replacement which is cost-effective and which does not require repetition of the endoscopy.     

Long-term follow-up of consequences of percutaneous endoscopic gastrostomy (PEG) tubes in nursing home patients

PEG (percutaneous endoscopic gastrostomy) tubes are frequently placed in nursing home patients. The aim of this study was to assess retrospectively the long-term changes in functional and nutritional statuses, tube-related complications, and factors influencing survival in 46 nursing home residents, mean age 73.6 years (range 19–96). Functional status was evaluated by a standard rehabilitation medicine scale. Nutritional status was evaluated by serum albumin and cholesterol concentrations and by weight. PEG-related complications requiring hospitalization or emergency room or clinic evaluations were noted. Additionally, changes in resuscitation status were noted. The predominant indication for PEG placement was dementia (52%). At PEG placement, 48% of patients had total functional impairment. Regardless of the severity of impairment, no patient's functional status improved after PEG. Nutritional status did not improve significantly. Mortality approached 50% and 60% at 12 and 18 months, respectively, and was significantly related to age, resuscitation status, and serum albumin concentration. All patients under 40 years of age at PEG survived, in contrast to 41.3% of patients over 40 years of age (P<0.001). Sixty-three percent of patients who were full code at PEG placement survived, in contrast to 10% of no code patients (P<0.001). Albumin 3.5 g/dl at PEG or thereafter was associated with improved survival (P<0.001) as compared to albumin <3.5 g/dl. PEG-related complications occurred in 34.7% of patients, and the first occurred four months after PEG. We conclude that realistic expectations of what PEG can accomplish be a factor in the decision to place a PEG tube in nursing home patients.     

Percutaneous endoscopic gastrostomy and outcome in dementia

The use of percutaneous endoscopic gastrostomy for the administration of food and medications in patients with dementia has been on an increase. Many studies have failed to demonstrate the positive outcome expected of this feeding modality for the indications that required tube placement. Hence, the concept of feeding through gastrostomy tubes has become the subject of much discussion and controversy in recent times. We have reviewed the literature with regard to outcome in older patients with dementia and percutaneous endoscopic gastrostomy with respect to nutritional parameters, quality of life, and survival. A brief discussion on ethical and legal aspects is included. Much of the data do not suggest that outcome in dementia is favorably improved after percutaneous gastrostomy.     

Percutaneous endoscopic gastrostomy feeding in AIDS*

Reduced energy intake is the most important reason for weight loss in advanced human immunodeficiency virus (HIV) infection. From January 1989 to August 1995 enteral feeding via a percutaneous endoscopic gastrostomy tube (PEG) was offered to all human immunodeficiency virus(HIV)/AIDS patients attending Fairfield Hospital, Melbourne who were unable to maintain 85% ideal body weight. A total of 71 patients received enteral feeding (1000–2000 kcal/day) for a median period of 161 days (range 4–644 days). Fifty-one (72%) patients gained 5.8 ± 4.4kg (range 0.4 - 19.2kg). Nine gained 10 kg or more. The median time to maximum weight was 74 days after PEG insertion. Those who gained weight had a longer median survival, but this difference was not statistically significant (210 vs 109 days, P=0.07). The only predictor of weight gain was a CD4 count greater than 100/μL. Patients who gained weight reported improved quality of life and increased independence. However, early complications, especially wound infection, were common. Although these data have been gathered retrospectively, our experience suggests that enteral feeding can maintain or improve nutritional status and may improve quality of life in advanced HIV infection.     

Percutaneous endoscopic gastrostomy associated gastric metastasis

An interesting case of gastric metastasis of head and neck cancer after percutaneous endoscopic gastrostomy (PEG) placement is presented. Gastric metastases may appear in 3 morphologic varieties endoscopically. They may be multiple nodules of varying size, submucosal tumor masses with tip ulceration, or nonulcerated masses. Histologically, they may be seen as microscopic infiltration, a gross nodule, gross ulceration, or a gross hypertrophied wall. A case of PEG associated gastric metastasis has been reported almost every year since 1989. Even then, PEG placement by pull method continues to be a common procedure for patients diagnosed with head and neck cancer. The mechanism of gastric metastasis in patients with PEG is unclear. Seeding as well as hematogenous and lymphatic spread to traumatized tissue may be the cause.
