Besides its well-known 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 placeme展开更多

Methods： A total of 43 patients with severe craniocerebral injury admitted to our department from January 2008 to December 2012 received PEG followed by nutritional therapy. There were other 82 patients who were prescribed nasal-feeding nutrition. Nutrition status was evaluated by comparing serum albumin levels, and the incidence of pulmonary infection 1 week before and 2 weeks after operation was identified and compared. Results： Both PEG and nasal-feeding nutrition therapies have significantly elevated serum albumin levels （P〈0.05）. Serum albumin levels before and after nutritional therapies showed no significant difference between the two groups （P〉0.05）. The incidence of pulmonary infection in PEG group was significantly decreased compared with that in nasal-feeding nutrition group （P〈0.05）. Conclusion： PEG is an effective method for severe craniocerebral injury patients. It can not only provide enteral nutrition but also prevent pulmonary infection induced by esophageal reflux.展开更多

METHODS ： In a prospective, randomized, controlled study 36 patients with recurrent or persistent ventilatorassociated pneumonia （VAP） and GER 〉 6% were divided into PEG group （n=16） or non-PEG group （n = 20）. Another 11 ventilated patients without reflux （GER 〈 3%） served as control group. Esophageal pH-metry was performed by the ＂pull through＂ method at baseline, 2 and 7 d after PEG. Patients were strictly followed up for semi-recumbent position and control of gastric nutrient residue. RESULTS： A significant decrease of median （range） reflux was observed in PEG group from 7.8 （6.2-15.6） at baseline to 2.7 （0-10.4） on d 7 post-gastrostomy （P 〈 0.01）, while the reflux increased from 9 （6.2-22） to 10.8 （6.3-36.6） （P〈 0.01） in non-PEG group. A significant correlation between GER （%） and the stay of nasogastric tube was detected （r= 0.56, P〈 0.01）. CONCLUSION： Gastrostomy when combined with semi- recumbent position and absence of nutrient gastric residue reduces the gastroesophageal reflux in ventilated patients.展开更多

METHODS： We retrospectively analyzed data for 252 out of 285 patients who underwent PEG at our hospital from 1999 to 2008 after PEG were defined as： Enteral nutrition problems （1） patients who required ≥ 1 mo after surgery to switch to complete enteral nutrition, or who required additional parenteral alimentation continuously; or （2） patients who abandoned switching to enteral nutrition using the gastrostoma and employed other nutritional methods. We attempted to identify the predictors of problem cases by using a logistic regression analysis that examined the patients＇ backgrounds and the specific causes that led to their problems. RESULTS： Mean age of the patients was 75 years, and in general, their body weight was low and their overall condition was markedly poor. Blood testing revealed that patients tended to be anemic and malnourished. A total of 44 patients （17.5%） were diagnosed as having enteral nutrition problems after PEG. Major causes of the problems included pneumonia, acute enterocolitis （often Clostridium difficile-related）, paralytic ileus and biliary tract infection. A multivariate analysis identified the following independent predictors for problem cases： （1） enteral nutrition before gastrectomy （a risk reduction factor）; （2） presence of esophageal hiatal hernia; （3） past history of paralytic ileus; and （4） presence of chronic renal dysfunction. CONCLUSION： Enteral nutrition problems after PEG occurred at a comparatively high rate. Patient background analysis elucidated four predictive factors for the problem cases.展开更多
