Since its introduction in 1980, percutaneous endoscopic gastrostomy (PEG) has become the procedure of choice for long-term enteral feeding in patients who are unable to take adequate oral nutrition. Traditionally, gastroenterologists have waited for 24 hr after PEG tube placement before initiating feedings. However, recently published data have described the safety and efficacy of initiating PEG tube feedings as early as 3 hr after PEG tube placement. The objectives of this study were to determine how many hours after PEG tube placement practicing gastroenterologists initiate feedings and to determine whether they were aware of the pertinent literature. A four-page questionnaire was mailed to 35 practicing gastroenterologists, and the data gathered were analyzed using the SAS statistical package. A majority (81.5%) were aware of articles published in the last six years regarding the safety and efficacy of early initiation of feeding after PEG; of interest, however, only 10.7% were initiating feedings less than 3 hr after PEG tube placement. In conclusion, there exists a discrepancy between published recommendations and clinical practice regarding early initiation of feedings after PEG tube placement in this group of gastroenterologists who were surveyed. 相似文献

Background Percutaneous endoscopic gastrostomy (PEG) is the preferred method for providing enteral nutritional support in patients with dysphagia. We examined gastric antral myoelectrical activity and gastric emptying before and after PEG tube placement to evaluate the effects of PEG on gastric motility.Methods PEG was performed in 41 patients; 21 fed by total parenteral nutrition (TPN) and 20 who received nasogastric tube feeding (NGF). Antral myoelectrical activity and gastric emptying were examined before and 4 weeks after PEG tube placement.Results The percentage of normal-range electrogastrograms (EGGs) was significantly lower in the TPN group than in the NGF group in both the pre- and postprandial periods before PEG tube placement. Enteral feeding after PEG tube placement improved gastric motility in the patients with TPN. The percentage of normal-range EGGs increased significantly after PEG tube placement in both the pre- and postprandial periods, and plasma concentrations of paracetamol increased significantly after PEG tube placement in patients with TPN. A total of 7.3% of the patients developed the complication of gastroesophageal reflux (GER) after PEG tube placement. Gastric myoelectrical activity and gastric emptying were improved in these patients with GER after PEG tube placement. In contrast, the prevalence of esophageal hiatus hernia was significantly higher in patients with GER after PEG tube placement than in patients without GER after PEG tube placement.Conclusions Prolonged TPN with bowel rest induces physiological dysfunction of gastric motility. Enteral nutrition is the preferable physiological nutritional route. GER after PEG tube placement is not related to gastric motility. Esophageal hiatus hernia seems to be a major risk factor for GER complications after PEG tube placement. 相似文献

The aim of this study is to determine if the endoscopic presence of esophagitis predicts aspiration pneumonia after the initiation of enteral feedings in a newly placed PEG tube. A retrospective analysis of 278 patients who received a PEG tube from November 1999 to June 2002 was performed. All PEG procedures performed by a single endoscopist were reviewed from the GI Trac database at the Medical University of South Carolina. Eleven of the procedures were aborted due to technical difficulties. Nine patients received the PEG for gastric decompression only. Seven patients died within 14 days of PEG placement from non-PEG-related complications and were excluded. The resulting 251 patients included for our analysis successfully had PEG tube placement and had at least 14 days of enteral feeding. Esophagitis was defined macroscopically by the endoscopic presence of mucosal edema, friability, or obscurity of the normal vascular pattern in the distal esophagus. Aspiration was defined as the witnessed regurgitation of or tracheal suctioning of PEG feedings. Pneumonia as a consequence of aspiration was defined by development of fever and new infiltrate on chest radiograph within 14 days of PEG placement. Two hundred fifty-one patients had PEG placement (M, 127; F, 124; average age, 62.4 year; age range, 18-95 years) performed by a single endoscopist over a 32-month period. Fourteen (5.6%) of these patients had clinically evident pulmonary aspiration, with seven of them developing pneumonia. Thirteen (93%) of these patients had normal esophageal mucosa. One of the 24 patients (4%) with esophagitis or esophageal ulceration present endoscopically had an aspiration event with subsequent pneumonia. None of the 20 patients found to have some other form of esophageal pathology had an aspiration event. The overall incidence of aspiration pneumonia after the initiation of PEG feedings was 2.7% (7/251). The odds ratio that the presence of esophagitis would predict the development of aspiration pneumonia was 1.60, with a 95% confidence interval of 0.18 to 13.89. This study argues that the presence of esophagitis alone does not increase the risk of aspiration pneumonia from PEG feedings. Other factors apart from esophagitis play an important role in the incidence of aspiration pneumonia with PEG feeding 相似文献

BACKGROUND AND STUDY AIMS: PEG placement is routinely used for enteral feeding; in some cases PEG is not feasible or indicated due to technical difficulties, such as gastric herniation, organ interposition, or presence of gastroparesis. In these cases, surgical gastrostomy or jejunostomy are possible alternatives; more recently, direct percutaneous jejunostomy (DPEJ) has been proposed to avoid surgical intervention. The aim of the study was to evaluate the necessity, technical feasibility and outcome of DPEJ in a group of patients consecutively proposed for PEG placement. PATIENTS AND METHODS: In each patient proposed for PEG placement, an upper gastrointestinal endoscopy was performed, and then a pull traction removal gastrostomy tube (18-20 F) was inserted. When PEG was not feasible or contraindicated, a variable stiffness pediatric videocolonscope was used to reach the jejunum: then DPEJ was performed with the same technique and materials as PEG. In both groups enteral feeding was started 24h after the endoscopic procedure, using an enteral feeding pump and the same nutritional schedules. RESULTS: In a 1-year period 90 patients were proposed for PEG placement; PEG could not be performed for technical reasons in 8 (gastric herniation in 1; organ interposition in 7) and gastroparesis in 1. In one patient both PEG and DPEJ were not feasible for organ interposition. The duration of the endoscopic procedure was slightly longer in DPEJ (mean 20 min versus 15 min). No complications related to the endoscopic procedure were observed in both DPEJ and PEG patients. No nutritional complication were observed in the DPEJ group. CONCLUSION: In our experience, PEG was not feasible or contraindicated in about 10% of patients proposed for. In these patients, DPEJ was placed: the procedure resulted to be feasible and safe with the use of a pediatric videocolonscope to easily reach the jejunum. The insertion of DPEJ did not change the nutritional management of enteral feeding. However, long-term effects or complications remain to be evaluated in larger studies. 相似文献

BACKGROUND: Artificial feeding by a percutaneous endoscopic gastrostomy (PEG) tube in patients with dementia has increased since the introduction of the endoscopic method of tube placement. Few studies have documented survival benefit from this intervention. This report reviews our experience with PEG tube placement for feeding patients with dementia. METHODS: All consultations for PEG tube placement were evaluated by a certified nutrition support nurse (L.M.M.) in consultation with a member of the gastroenterology physician staff (T.O.L.) for 24 months. Evaluation included the attainment of a brief medical history, a physical examination, and a review of comorbid conditions, laboratory variables for nutrition status, and bleeding risk. Interviews with patients or surrogates were conducted, including an explanation of the risks and benefits of PEG tube placement. A Kaplan-Meier survival curve was used to compare the median survival between patients with dementia who received a PEG tube and patients with dementia in whom PEG tube placement was refused. RESULTS: We received 41 consultations for PEG tube placement in patients with dementia. Percutaneous endoscopic gastrostomy was performed in 23 patients; 18 patients met the medical criteria for PEG tube placement, but surrogates refused placement. The median survival for the 23 patients who underwent PEG was 59 days; the median survival for the 18 patients who did not undergo PEG was 60 days. CONCLUSION: There seems to be no survival benefit in patients with dementia who receive artificial feeding by a PEG tube. 相似文献

Background: Upper gastrointestinal (GI) hemorrhage after percutaneous endoscopic gastrostomy (PEG) is sometimes reported as one of the serious complications. Our purpose was to clarify the cause of upper GI hemorrhage after PEG. Patients and Methods: We retrospectively investigated the causes of upper GI hemorrhage among a total of 416 patients out of 426 consecutive patients who underwent PEG in our institution, excluding 10 patients who showed upper GI tumors on PEG placement. Results: Among 17 patients who developed upper GI hemorrhage after PEG, three and four patients showed PEG tube placement and replacement‐related hemorrhage, respectively; these lesions were vascular or mucosal tears around the gastrostomy site. Ten patients experienced 12 episodes of upper GI hemorrhage during PEG tube feeding. The lesions showing bleeding were caused by reflux esophagitis (five patients), gastric ulcer (two patients), gastric erosion due to mucosal inclusion in the side hole of the internal bolster (two patients), and duodenal diverticular hemorrhage (one patient). Anticoagulants were administered in six patients, including four patients with replacement‐related hemorrhage and one patient each with reflux esophagitis and gastric ulcer. Conclusions: Reflux esophagitis was the most frequent reason for upper GI hemorrhage after PEG. The interruption of anticoagulants should be considered for the prevention of hemorrhage on the placement as well as replacement of a gastrostomy tube. 相似文献

BACKGROUND: Percutaneous endoscopic tube placement can be problematic under certain circumstances: absence of transillumination of the abdominal wall, percutaneous jejunostomy in patients with a PEG tube and recurrent aspiration, enteral feeding access after gastrectomy, and obstruction of the upper GI tract. As an alternative in these problematic situations, a technique was developed for placing feeding tubes under visual control by using mini-laparoscopy. METHODS: Placement of a feeding tube with mini-laparoscopy with the patient under conscious sedation was considered for 17 patients in whom standard PEG placement was impossible. Techniques used were the following: combined mini-laparoscopy/endoscopy for placement of a percutaneous gastrostomy or jejunostomy, and mini-laparoscopic-guided direct tube placement in cases of obstruction of the upper GI tract. OBSERVATIONS: In 13 patients, mini-laparoscopic-assisted tube placement was successful. In 4 patients, adhesions or peritoneal carcinomatosis prevented laparoscopic visualization of the stomach or small bowel. The combined mini-laparoscopic/endoscopic approach allowed a successful insertion of gastric tubes in 6 patients and jejunal tubes in 4 patients. Direct insertion of a percutaneous endoscopic jejunostomy tube without enteroscopy was feasible in all 3 patients with obstruction of the upper GI tract. No complication occurred. CONCLUSIONS: Mini-laparoscopy-assisted tube placement is a simple and safe alternative when endoscopic percutaneous tube placement is problematic or not feasible. 相似文献

Background
Percutaneous endoscopic gastrostomy (PEG) is the procedure of choice for long-term enteral feeding.Objective
This prospective observational study was carried out to compare the safety of commencing feeding 3 h compared to 16–24 h after PEG tube placement.Methods
One hundred and ten patients with oropharyngeal malignancies who had consented for PEG were enrolled. Trial-specific consent and IRB approval were not obtained because at the time when this study was done, this was not mandatory for observational studies which involved standard procedures. Alternate patients were started on early feeding within 3 h (group I) or after overnight observation of 16 to 24 h (group II). Five hundred milliliters of Ringer's lactate was infused over 4 h initially, followed 2 h later by 200 mL of formula feed. The patients were advised to take bolus feeds of 200 mL every 2 h and oral feeds ad libitum from the next day. All patients were evaluated on days 1, 2, 7, and 30.Results
There were 55 patients (47 males) in group I and 54 patients (38 males) in group II who were matched for age (mean age 46.1 and 46.1 years, respectively). Complications included PEG site infection (1), peristomal leak (3), and displacement of the PEG tube (1) in group I. PEG site infection was seen in five patients in group II. All the complications were managed conservatively on an ambulatory basis.Conclusion
Initiation of tube feeding 3 h after an uncomplicated PEG was safe, well tolerated, and helped to reduce the hospital stay. 相似文献9.

Percutaneous endoscopic gastrostomy(PEG)is the preferred route of feeding and nutritional support in patients with a functional gastrointestinal system who require long-term enteral nutrition.Besides its wellknown advantages over parenteral nutrition,PEG offers superior access to the gastrointestinal system over surgical methods.Considering that nowadays PEG tube placement is one of the most common endoscopic procedures performed worldwide,knowing its indications and contraindications is of paramount importance in current medicine.PEG tubes are sometimes placed inappropriately in patients unable to tolerate adequate oral intake because of incorrect and unrealistic understanding of their indications and what they can accomplish.Broadly,the two main indications of PEG tube placement are enteral feeding and stomach decompression.On the other hand,distal enteral obstruction,severe uncorrectable coagulopathy and hemodynamic instability constitute the main absolute contraindications for PEG tube placement in hospitalized patients.Although generally considered to be a safe procedure,there is the potential for both minor and major complications.Awareness of these potential complications,as well as understanding routine aftercare of the catheter,can improve the quality of care for patients with a PEG tube.These complications can generally be classified into three major categories:endoscopic technical difficulties,PEG procedure-related complications and late complications associated with PEG tube use and wound care.In this review we describe a variety of minor and major tube-related complications as well as strategies for their management and avoidance.Different methods of percutaneous PEG tube placement into the stomach have been described in the literature with the"pull"technique being the most common method.In the last section of this review,the reader is presented with a brief discussion of these procedures,techniques and related issues.Despite the mentioned PEG tube placement complications,this procedure has gained worldwide popularity as a safe enteral access for nutrition in patients with a functional gastrointestinal system. 相似文献

A randomized prospective trial was designed to evaluate the preventive treatment of esophagitis in 31 intensive care patients who had a nasogastric feeding tube for at least 10 days. Fourteen patients (group B) received no preventive treatment while 17 patients (group A) received 300 mg of cimetidine every 6 h intravenously and 11 g of colloidal aluminium phosphate every 4 h per os. All patients were fed a standard diet through their nasogastric tube at a constant rate of 30 Kcal/kg/day. Endoscopic controls at day 1 and 10 showed that the number of initial and final esophagitis was not different in groups B and A: 7 and 8 at day 1, 11 and 10 at day 10, respectively. The inefficiency of this preventive treatment suggested that acid gastroesophageal reflux is not a major factor in the occurrence of nasogastric feeding tube-induced esophagitis. However as esophagitis is associated with a more severe Knaus index and a greater number of gastric stress ulcer risk factors, it is suggested that decreased defense of the mucosa may be a key factor in the occurrence of this type of esophagitis. 相似文献

OBJECTIVES: Percutaneous endoscopic gastrostomy (PEG) is a widely used method for providing long-term administration of tube feeding. Different indications in relation to diseases, impairments and nutritional factors for PEG placement have been mentioned in guidelines. Treatment with PEG has not been described previously for tuberculosis (TB). Our aim was to identify and describe indications and contributing factors for PEG placement in TB patients. METHODS: A retrospective medical record review was conducted of 32 TB patients who required PEG from March 1996 to April 2004. Indications and contributing factors for PEG placement were analysed. RESULTS: PEG placement was based on three different indications. In 18 patients, PEG was used to administer tube feeding, in 4 patients anti-tuberculosis drugs were administered and in 10 patients both tube feeding and antituberculosis drugs were administered. Contributing factors for PEG placement were swallowing disabilities, weakness, anti-tuberculosis drugs and their side effects, pain of neuralgic origin, hiccups and refusal of food and drugs. CONCLUSIONS: In TB, imminent and overt malnutrition, as well as the administration of drugs with a curative aim, are new indications for PEG placement. The use of PEG can overcome various problems in TB treatment and prevent treatment default. 相似文献

OBJECTIVE: To determine the relative importance of factors influencing physicians to use tube feedings in patients lacking decision-making capacity. DESIGN: Survey. SETTING AND PARTICIPANTS: Four hundred thirty-nine members of the Missouri Academy of Family Physicians. MEASUREMENTS: Using a mailed questionnaire, physicians were asked for a decision about feeding tube placement in an 89-year-old man who was unable to swallow or communicate after a stroke. Changing the conditions of the scenario, we then evaluated the influence of patient age, duration of disability, a living will, the Cruzan decision, and family preferences on the physician's decision. RESULTS: After reading the initial case history, 47% of physicians opposed tube feedings. Physicians who were told that the patient signed a living will specifically excluding tube feedings were more likely to oppose tube feedings than those who were told that he signed only a standard living will (53% vs 42%; P = 0.02). Forty-two percent of physicians who initially suggested a feeding tube changed their recommendation if the family opposed it. Sixty-six percent of physicians who initially opposed a feeding tube changed their recommendation if the family "pushed" for it. Thirty-three percent of physicians who initially opposed tube feedings under the living will scenario would favor tube feedings if the patient had not signed a living will. Twenty-two percent of physicians who initially opposed tube feedings would change to favor them if the issue had arisen before the Cruzan decision. CONCLUSIONS: Among this group of physicians, there was no consensus on whether tube feedings should be initiated. However, it was found that the family's opinion was the most influential factor affecting the physician's recommendation about tube feedings. Most physicians endorsed family preferences for tube feedings even when this intervention was specifically opposed in the patient's living will. 相似文献

Postoperative nutrition is best provided enterally; however, patients often develop intolerance to enteral feedings. Our aim was to prospectively identify abdominal examination and jejunal pressure activity associated with postoperative intolerance of enteral feedings. Twenty-nine patients underwent abdominal operation and needle catheter jejunostomy placement. Elemental tube feedings were started on the day after surgery and advanced to the caloric goal rate over three days. Patients whose feedings were slowed at the attending surgeon's discretion were defined as intolerant. Jejunal manometry and a standardized abdominal exam were performed on postoperative days 1, 3, and 5. Fifteen patients (52%) were intolerant of tube feedings and had decreased jejunal motor activity but more active bowel sounds prior to feedings. After feedings, intolerant patients developed abdominal distension, but other abdominal findings were inconsistent. A marked decrease in phase II of the migrating motility complex (MMC) and the lack of a fed response were present in both groups. The overall jejunal motility present on day 1 following surgery identifies patients that will not tolerate enteral feedings. The abdominal examination, MMC parameters, and motor response to feeding did not predict feeding intolerance. 相似文献

OBJECTIVE: To determine the safety of percutaneous endoscopic gastrostomy (PEG) tube placement for nutritional support and/or defined therapeutic enteral nutrition (TEN) in adult patients with Crohn's disease. DESIGN: A prospective, observational study of patients with Crohn's disease in whom PEG tubes were placed for nutritional support or TEN. SETTING: A specialist nutrition clinic at a gastroenterology tertiary referral centre in Harrow, UK. PARTICIPANTS: Nine patients with Crohn's disease. Seven patients had nutritional failure and were unable to tolerate nasogastric feeding, and two patients were recruited in whom TEN therapy for active disease was indicated. The age range was 21-52 years (median, 30 years). Five patients were female; all had had previous ileo-colonic resections, one had a gastro-enterostomy and one had a non-healing Crohn's-related gastric ulcer. INTERVENTIONS: PEG insertion (Fresenius, Frecka 9 Fr) was performed at endoscopy with intravenous sedation. Follow-up with tubes in situ was for a median of 37 weeks (range, 4-276 weeks), and for a further median of 80 weeks (range, 52-120 weeks) in those whose tubes have been removed. MAIN OUTCOME MEASURES: The level of disease activity, nutritional status/body mass index and any complications associated with PEG tube placement were recorded. RESULTS: PEG was achieved in all patients; the only complication was a minor superficial entry site infection. Five patients continue to use PEG feeding to good effect, including healing of the Crohn's-associated ulcer. One patient now eats normally having regained target weight, and three require parenteral nutrition, having failed to achieve nutritional sufficiency despite an optimal enteral regimen via the PEG. An adverse body image in one of these patients (an opiate abuser with a long psychiatric history) was probably contributory to PEG failure. There was no peristomal or fistulous disease. CONCLUSIONS: Although nutrition via PEG is not always successful, failures are of enteral nutrition, and not of the means. PEG use in selected patients with Crohn's disease appears safe and can prove a useful addition to therapeutic options. 相似文献

OBJECTIVES: Percutaneous endoscopic gastrostomy (PEG) tube placement is a widely used method for long-term enteral feeding of demented patients unable to take sufficient food by mouth. National time trends in PEG tube use over the last decade have not been previously reported. The objective of this study was to determine whether use of PEG tubes for patients with dementia has changed over time and by race. DESIGN: Retrospective cohort study. SETTING: All Veterans Affairs hospitals. PARTICIPANTS: Using an administrative database of the Veterans Health Administration, all veterans with dementia and all veterans who received a PEG tube were identified between fiscal years 1990-2001. MEASUREMENTS: Proportion of PEG tube placement for dementia patients over time and by race. RESULTS: Four hundred thirteen thousand six hundred twenty-seven dementia patients aged 60 and older were identified, of whom 6,464 (1.6%) received a PEG tube. Use of PEG tubes for dementia patients increased during the first half of the decade but subsequently decreased almost to baseline after peaking in 1996 (1990: 1.2%, 1996: 1.8%, 2001: 1.3%). Time trends in the use of PEG tube feeding for dementia patients varied by race. Specifically, the relative risk for PEG tube placement in African-American dementia patients increased from 1.65 (95% confidence interval (CI)=1.25-2.17, FY 1990) to 1.97 (95% CI=1.62-2.4, FY 2001). CONCLUSION: Although the overall use of PEG tube feeding for dementia patients decreased over time, rates in use and changes in use over time varied significantly by race. Reasons for the differential use of this procedure should be explored. 相似文献

OBJECTIVE: Early enteral feedings may improve outcomes in critically ill patients. Recently, transnasal endoscopy with an ultrathin transnasal endoscope has been shown to be of value for diagnostic endoscopy without conscious sedation. We developed a technique for the placement of postpyloric feeding tubes in critically ill patients using transnasal endoscopy. We describe our initial experience in a consecutive series of patients. METHODS: We collected data on consecutive intensive care unit patients undergoing bedside transnasal endoscopy for nasoenteric feeding tube placement using a standardized technique. Tube position was confirmed in all patients with a plain abdominal radiograph. Tube placement was deemed successful if the feeding tube traversed the pylorus. RESULTS: Transnasal endoscopy was completed in all fourteen patients, as was placement of a feeding tube. Feeding tubes were successfully placed in the jejunum or duodenum in 13 of the 14 patients (93%). Tubes remained in place from 3 to 45 days (mean 16 days). Two patients required conscious sedation during tube placement, and two ultimately required percutaneous gastrostomy. CONCLUSIONS: Transnasal endoscopy allows simple and successful postpyloric feeding tube placement at the bedside of critically ill patients. This method can facilitate early enteral feeding in intensive care units. 相似文献

Replacement of gastrostomy tube in patients under-going 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. 相似文献

The percutaneous endoscopic gastrostomy tube. medical and ethical issues in placement 总被引:4,自引:0,他引:4
OBJECTIVE: Offering and recommending PEG tube placement to patients has been a topic of considerable interest in the medical literature. The role of individual health care professionals in the decision making process is poorly defined. PEG tubes are often placed inappropriately because of unrealistic and inaccurate expectations of what they can accomplish in patients unable to tolerate adequate oral intake. We have developed an algorithm for PEG placement for the geriatric, oncology, and neurology patients based on a critical review of current literature. METHODS: An extensive review of the literature was performed focusing on PEG tube placement in oncology, neurology, and geriatric patients. This algorithm was developed to provide both the primary care provider and the specialist with appropriate indications for PEG placement in these patient populations. RESULTS: Appropriate indications for PEG placement are 1) Esophageal obstruction (e.g., esophageal cancer), 2) Neurologic etiology of dysphagia without obstruction (e.g., status post cerebrovascular accident, pseudobulbar palsy), 3) Prolonged refusal to swallow without evidence of concomitant terminal illness (e.g., protracted pseudodementia due to severe depression), 4) Supplemental nutrition for patients undergoing chemotherapy or radiation therapy. CONCLUSIONS: If no physiologic benefit is expected with PEG placement (anorexia-cachexia syndrome), the health care team has no obligation to offer or perform an intervention. This same principle would apply if intervention improves physiologic states but has no effect on quality of life (e.g., permanent vegetative state). Small-bore feeding tubes are cost effective and relatively safe for enteral feedings of up to 6-8 weeks. This is especially pertinent in the population with acute neurological deficits, in which prognostication on extent of impairment is best estimated by communication with neurologist. In the geriatric population there is no proved benefit in weight gain or markers of nutrition (albumin, prealbumin) in patients with malnutrition due to impaired oral intake. 相似文献

Benefit of uncooked cornstarch in the management of children with dumping syndrome fed exclusively by gastrostomy 总被引:1,自引:0,他引:1

Objective: Children with dumping syndrome fed exclusively by gastrostomy are difficult to manage because liquid diets are given directly into the antrum. The gastric contents are emptied rapidly into the small intestine, with consequent hyperglycemia followed by a delayed hypoglycemia and multiple, often debilitating, symptoms. Uncooked cornstarch is a complex carbohydrate that provides a slow and continuous glucose source and may delay gastric emptying. The objective of this study was to determine the efficacy of uncooked cornstarch in the treatment of these children.
Methods: The medical records of eight children with dumping syndrome fed exclusively by gastrostomy were reviewed. Dumping syndrome was diagnosed if there was consistent symptomatology, rapid gastric emptying, and abnormal glucose measurements after a glucose tolerance test. Enough uncooked cornstarch to match hepatic glucose production for 4 h was added to control hypoglycemia, and the feeding formula was modified to control hyperglycemia.
Results: All patients had debilitating symptoms. Weight z-score on admission was −2.31 ± 0.29. Glucose shifts were controlled in all. There was a significant difference between the maximum (221.3 ± 19.3 mg/dl vs 121.3 ± 6.9 mg/dl; p < 0.008 ) and minimum serum glucose (47 ± 7.8 mg/dl vs 65.6 ± 4 mg/dl; p < 0.04 ) before and after uncooked cornstarch. Weight increased from 11.87 ± 1.4 kg to 15.10 ± 2.3 kg ( p = 0.06 ). In seven patients, bolus feedings were successfully administered, and symptoms improved or resolved.
Conclusions: Uncooked cornstarch controlled the glucose shifts, resolved most of the symptoms, allowed bolus feedings, and enhanced weight gain in these children. 相似文献

Conclusions: Uncooked cornstarch controlled the glucose shifts, resolved most of the symptoms, allowed bolus feedings, and enhanced weight gain in these children. 相似文献

The use of percutaneous endoscopic gastrostomy (PEG) tubes for enteral feeding is widespread, although their superiority to other feeding devices, such as nasoenteric tubes (NET), has not been substantiated. We retrospectively compared clinical outcomes in patients who received enteral feeding via PEG (n = 80) or NET (n = 29) from 1984 to 1988. Mean follow-up was 192 days in the PEG group and 141 days in the NET group. Changes in nutritional and performance status were similar in both groups. Aspiration pneumonia occurred within 14 days of tube placement in 6% and 24% (p = 0.01) of the PEG and NET patients, respectively. With the exception of tube replacement, cumulative rates of minor and major complications (including aspiration pneumonia) were similar in both groups during follow-up. None of the clinical variables that were assessed correlated with the development of aspiration pneumonia. Mortality was similar in both groups. These results suggest that, for long-term enteral feeding, PEG offers no substantial advantages over NET with respect to patient nutrition, performance, or survival. The reasons for the observed difference in short-term aspiration pneumonia rates are unknown, and must be investigated prospectively. 相似文献
