Abstract
There are many misconceptions surrounding the diagnosing and treatment of malnutrition and around feeding people with enteral nutrition (EN). Often the decisions made by clinicians are made from anecdote or guidelines that may be out of date or supported by low-quality evidence. In this article, we will discuss different aspects of diagnosing malnutrition and delve deeper into the science and evidence behind certain recommendations. Our goal is to better equip the reader with the most current data-supported recommendation, such as indications, contraindications, complications of EN, tube and ostomy complications, types and use of specialized enteral formulas, and home management.

Abstract
Objective To avoid perioperative complications caused malnutrition, nutrition therapy is necessary in gastric outlet obstruction (GOO) patients. Compared to parenteral nutrition (PN), enteral nutrition (EN) is associated with many advantages. This study aimed to investigate whether preoperative EN has beneficial clinical effects compared to preoperative PN in gastric cancer patients with GOO undergoing surgery. Methods According to the methods of preoperative nutrition therapy, 143 patients were divided into EN group (n=42) and PN group (n=101) between January 2013 and December 2017 at the Chinese People’s Liberation Army General Hospital. Multiple logistic regression models were used to assess the association between the methods of preoperative nutrition therapy and postoperative day of flatus passage. The generalized additive model and two-piecewise linear regression model were used to calculate the inflection point of the preoperative nutritional therapy time on the postoperative day of flatus passage in the PN group. Results EN shortened the postoperative day of flatus passage in gastric cancer patients with GOO, which is a protective factor, especially in patients who underwent non-radical operations and the postoperative day of flatus passage reduced when the preoperative PN therapy was up to 3 d and a longer PN therapy (>3 d) did not accelerate the postoperative recovery of gastrointestinal functions. Conclusions Preoperative EN therapy would benefit gastric cancer patients with GOO by accelerating postoperative recovery. For patients with absolute obstruction, no more than 3-day PN therapy is recommended if patients can tolerate general anesthesia and surgery.

Abstract
OBJECTIVES Jejunal tube feeding (JTF) is increasingly becoming the standard of care for children in whom gastric tube feeding is insufficient to achieve caloric needs. Given a lack of a systematic approach to the care of JTF in paediatric patients, the aim of this position paper is to provide expert guidance regarding the indications for its use and practical considerations to optimize its utility and safety. METHODS A group of members of the Gastroenterology and Nutrition Committees of the European Society of Paediatric Gastroenterology Hepatology and Nutrition and of invited experts in the field was formed in September 2016 to produce this clinical guide. Seventeen clinical questions treating indications and contraindications, investigations before placement, techniques of placement, suitable feeds and feeding regimen, weaning from JTF, complications, long-term care, and ethical considerations were addressed.A systematic literature search was performed from 1982 to November 2018 using PubMed, the MEDLINE, and Cochrane Database of Systematic Reviews. Grading of Recommendations, Assessment, Development, and Evaluation was applied to evaluate the outcomes.During a consensus meeting, all recommendations were discussed and finalized. In the absence of evidence from randomized controlled trials, recommendations reflect the expert opinion of the authors. RESULTS A total of 33 recommendations were voted on using the nominal voting technique. CONCLUSIONS JTF is a safe and effective means of enteral feeding when gastric feeding is insufficient to meet caloric needs or is not possible. The decision to place a jejunal tube has to be made by close cooperation of a multidisciplinary team providing active follow-up and care.

Abstract
The objective of this study was to verify the nasogastric tube position with neck ultrasound and subxiphoid ultrasound, by giving air-water mixture and auscultation and to compare the effectiveness of these methods with chest radiography. This is a single-center, prospective, single-blind study. Patients who were admitted to our emergency department and had an indication of nasogastric tube placement were included. Nasogastric tube localization was verified with neck ultrasound and subxiphoid ultrasound, by giving air-water mixture, auscultation, and direct radiography that was accepted as the ‘gold standard technique'. A total of 49 patients (27 Male, 22 Female) with a mean age of 58.3±22.7 years were included. Sensitivity of neck ultrasound was 91.5%, and positive predictive value was 100%. As for the subxiphoid ultrasound sensitivity was 78.72%. When neck ultrasound + subxiphoid ultrasound and giving water-air mixture were combined sensitivity reached 95.74%. Sensitivity of neck ultrasound + subxiphoid ultrasound + air-water mixture + auscultation was 97.87% and positive predictive value was 100%. In the light of our results, neck and subxiphoid ultrasound seem to be an alternative method for verifying nasogastric tube localization. Combination of the air-water mixture and auscultation with ultrasound improves the sensitivity.

Abstract
OBJECTIVES Clinical trials on tube feedings (TFs) have not been sufficiently powered to change practice patterns in acute pancreatitis (AP). We aimed to describe the use, duration, and resource utilization of TF in AP patients at an expert US center. METHODS Of 423 AP patients prospectively enrolled at the University of Pittsburgh Medical Center from 2004 to 2014, 139 (33%) received TF. Data on TF were assessed in 100 (72%) of 139 patients with complete data available. RESULTS Patients on TF were more likely to be male, be obese, have alcohol etiology, and have moderately severe (34% vs 19%) or severe AP (62% vs. 3%) (P < 0.05). Tube feedings were started after a median of 5 days (interquartile range, 3-8 days) from admission and were administered for a median of 39 days (interquartile range, 19-58 days). A nasojejunal route (95%) with an oligomeric formula (92%) was the preferred TF strategy. Feeding tube complications led to at least 1 endoscopic tube replacement in 42% of patients and to an unexpected health care visit in 29% of those discharged on TF (16/55 patients). CONCLUSIONS Tube feedings form an important component in the management of patients with moderately severe and severe AP. Further studies should define the optimal utilization of TF and ways to reduce TF-related complications.

Abstract
BACKGROUND Despite the use of prokinetic agents, the overall success rate for postpyloric placement via a self-propelled spiral nasoenteric tube is quite low. METHODS This retrospective study was conducted in the intensive care units of 11 university hospitals from 2006 to 2016 among adult patients who underwent self-propelled spiral nasoenteric tube insertion. Success was defined as postpyloric nasoenteric tube placement confirmed by abdominal x-ray scan 24 hours after tube insertion. Chi-square automatic interaction detection (CHAID), simple classification and regression trees (SimpleCart), and J48 methodologies were used to develop decision tree models, and multiple logistic regression (LR) methodology was used to develop an LR model for predicting successful postpyloric nasoenteric tube placement. The area under the receiver operating characteristic curve (AUC) was used to evaluate the performance of these models. RESULTS Successful postpyloric nasoenteric tube placement was confirmed in 427 of 939 patients enrolled. For predicting successful postpyloric nasoenteric tube placement, the performance of the 3 decision trees was similar in terms of the AUCs: 0.715 for the CHAID model, 0.682 for the SimpleCart model, and 0.671 for the J48 model. The AUC of the LR model was 0.729, which outperformed the J48 model. CONCLUSION Both the CHAID and LR models achieved an acceptable discrimination for predicting successful postpyloric nasoenteric tube placement and were useful for intensivists in the setting of self-propelled spiral nasoenteric tube insertion.

Abstract
A survey was performed to identify the practice associated with endoscopic placement of naso-jejunal (NJ) tubes. We had a total of 236 responses, of which 228 responded to the frequency of requesting X-ray after placing NJ tubes. The responses suggested that there was a strong variation in the practice. The practice was independent on clinicians’ area of interest, hospital setting or experience in endoscopy. Currently there are no accepted guidelines on this. Hence, we advise hospitals to have robust local guidelines until there is internationally agreed consensus.

Abstract
Nasogastric tube (NGT) insertion is a common procedure performed by residents and nursing staff to access the stomach. Although an apparently simple procedure, it is associated with technical difficulties and complications if proper care is not taken during insertion. We present a case of a 79-year-old female with multiple comorbidities who had a percutaneous enteral gastrostomy tube removed due to infection of an insertion site wound and a NGT was inserted for feeding. A few minutes post-insertion the patient developed shortness of breath and a drop in oxygen saturation. An immediate chest X-ray showed the NG tube traversing along the course of the trachea and the right main bronchus into the right upper abdomen with right-sided pneumothorax. The NG tube was immediately removed and a right chest drain inserted. Subsequent imaging showed right-sided pneumothorax with evidence of lung laceration and underlying lung collapse and diaphragmatic injury. The patient underwent a prolonged course of hospitalisation due to hospital-acquired pneumonia before being discharged upon clinical improvement. We highlight the fact that a simple and routine procedure such as NGT insertion can have devastating complications if due care is not taken. Along with a literature review, we provide and compare different methods to confirm correct placement of a NGT. The article also discusses important pearls for practising physicians and nursing staff to avoid such complications. Owing to the frequency of the procedure in hospitals and long-term care units, appropriate awareness among medical staff is necessary.

Abstract
INTRODUCTION Early postpyloric nasoenteric nutrition is considered an accepted method of nutritional support in critically ill patients. Both endoscopy and fluoroscopy placement of postpyloric nasoenteric tubes (PNTs) have the highest percentages of placement success rate. We aimed to evaluate the differences in efficacy and safety between endoscopy and fluoroscopy methods for the placement of PNTs in critically ill patients. METHOD We searched MEDLINE, Embase, and electronic databases of Cochrane Central Register of Controlled Trials. We included randomized controlled trials comparing endoscopy and fluoroscopy placement of PNTs in critically ill patients. Two reviewers assessed the quality of each study and collected data independently. We performed the meta-analysis with Cochrane Collaboration RevMan 5.3. RESULTS Three randomized controlled trials involving 243 patients were included. There were no significant differences in the placement success rate (RR, 0.99; 95% CI, 0.93, 1.06; z = 0.20, P = .84,) or procedure time (standardized mean difference, -0.08; 95% CI, -6.93, 6.77; z = 0.02, P = .98) between the 2 groups. No severe complications (digestive tract hemorrhage, perforation, respiratory problems, hemodynamic instability, or death) were noted in the three studies. There was a slight difference in the incidence of minor complications (RR, 8.12; 95% CI, 1.07, 61.53; z = 2.03, P = .04) between the 2 groups. CONCLUSIONS Endoscopy and fluoroscopy placement of PNTs can be accurately and safely performed in critically ill patients. Endoscopy may be at least equally as safe as fluoroscopy for the placement of PNTs.

Abstract
BACKGROUND Impaired motor and hormonal gastrointestinal functions have been implicated in the pathogenesis of acute pancreatitis. The aim of the present study was to investigate the predictive value of the Gastroparesis Cardinal Symptom Index and serum ghrelin in the development of clinically meaningful outcomes in patients with acute pancreatitis. METHODS This was a prospective clinical study. The Gastroparesis Cardinal Symptom Index and serum ghrelin were measured for 48 h after hospitalization. Univariate and multivariate logistic regression analyses were conducted. RESULTS The Gastroparesis Cardinal Symptom Index total score alone on day 2 was a significant predictor of oral feeding intolerance in both unadjusted (odds ratio 1.21 (1.01-1.46), P = 0.04) and adjusted (odds ratio 1.30 (1.01-1.69), P = 0.05) analyses. Adding ghrelin to Gastroparesis Cardinal Symptom Index further improved prediction in both unadjusted (odds ratio 1.26 (1.02-1.56), P = 0.03) and adjusted (odds ratio 1.53 (1.00-2.35), P = 0.05) analyses. CONCLUSION This pilot study demonstrates that the Gastroparesis Cardinal Symptom Index has a potential to be used as a predictor of oral feeding intolerance. Ghrelin, when combined with the Gastroparesis Cardinal Symptom Index, may further improve the predictive accuracy. These findings need to be confirmed in larger studies.

Abstract
Post-pyloric feeding (PF) allows the administration of enteral nutrition beyond the pylorus, either into the duodenum or, ideally, into the jejunum. The main indications of PF are: upper gastrointestinal tract obstructions, pancreatic rest (e.g., acute pancreatitis), gastric dysmotility (e.g., critically ill patients and chronic intestinal pseudo-obstruction) or severe gastroesophageal reflux with risk of aspiration (e.g., neurological disability). Physiological and clinical evidence derives from adults, but can also be pertinent to children. This review will discuss the practical management and potential clinical applications of PF in pediatric patients. Some key studies pertaining to the physiological changes during PF will also be considered because they support the strategy of PF management.

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

Abstract
Enteral feeding has become an important means of providing nutritional support to seriously ill patients. Placement of the feeding tube through the pyloric ring and past the ligament of Treitz into the proximal jejunum is critical to reduce the risk of gastroesophageal regurgitation and microaspiration. We started utilizing transnasal endoscopy for intestinal feeding tube placement, placing enteral tubes for 40 patients between March 2008 and February 2009. Although we achieved a high success rate comparable to previous reports, we experienced several cases of failure, which was corrected with repeated endoscopy. Based on these experiences, we modified our method by adding a "double-check" transnasal endoscopy through the other nasal passage. After April 2010, we have placed the feeding tube by "double-check" method for all patients (more than 40 patients) who required transnasal endoscopic feeding tube placement. We have not experienced any misplacement in all these patients after 24 h later with 100% successful rate since the introduction of "double-check" procedure. We describe our experience with "double-check" transnasal endoscopic feeding tube placement, which we found to be a helpful adjunct, for patients in intensive care unit.

Abstract
AIM: To compare fluoroscopic, endoscopic and guide wire assistance with ultraslim gastroscopy for placement of nasojejunal feeding tubes.
METHODS: The information regarding nasojejunal tube placement procedures was retrieved using the gastrointestinal tract database at Tongji Hospital affiliated to Tongji Medical College. Records from 81 patients who underwent nasojejunal tubes placement by different techniques between 2004 and 2011 were reviewed for procedure success and tube-related outcomes.
RESULTS: Nasojejunal feeding tubes were successfully placed in 78 (96.3%) of 81 patients. The success rate by fluoroscopy was 92% (23 of 25), by endoscopic technique 96.3% (26 of 27), and by guide wire assistance (whether via transnasal or transoral insertion) 100% (23/23, 6/6). The average time for successful placement was 14.9 ± 2.9 min for fluoroscopic placement, 14.8 ± 4.9 min for endoscopic placement, 11.1 ± 2.2 min for guide wire assistance with transnasal gastroscopic placement, and 14.7 ± 1.2 min for transoral gastroscopic placement. Statistically, the duration for the third method was significantly different (P < 0.05) compared with the other three methods. Transnasal placement over a guidewire was significantly faster (P < 0.05) than any of the other approaches.
CONCLUSION: Guide wire assistance with transnasal insertion of nasojejunal feeding tubes represents a safe, quick and effective method for providing enteral nutrition.

Abstract
Patients with upper gastrointestinal obstructions were previously managed with gastric decompression and parenteral feeding. The authors present their experience in 50 patients with obstructions chiefly due to complicated severe acute (n = 31) or chronic cystic pancreatitis (n = 11) using a double-lumen nasogastric decompression and jejunal feeding tube system (NGJ) held in place with a nasal bridle that passes through the obstructed gastroduodenal segments, allowing distal jejunal feeding, and at the same time decompresses the stomach to prevent vomiting and aspiration. The tip of the jejunal tube was placed approximately 40 cm down the jejunum to maintain pancreatic rest. Duration of feeding ranged from 1-145 days (median 25 days); 19 patients were discharged home with tube feeds. Only 1 patient could not tolerate feeding and needed to be converted to parenteral feeding. Average tube life was 14 days, with replacement being needed most commonly for kinking or clogging of the jejunal tube (56%) or accidental dislodgement (24%). The obstruction resolved spontaneously in 60%, allowing resumption of normal eating. Of the patients with severe acute pancreatitis or pancreatic pseudocysts, pancreatic rest resulted in resolution of the disease without surgery in 87%, and need for surgery in the remainder was put off for 31-76 days. Seven patients died predominantly of complications of acute pancreatitis between 1 and 31 days. In conclusion, NGJ feeding provides a relatively safe conservative management for critically ill patients with upper gastrointestinal obstructions, reducing the need for surgery and parenteral feeding.

Abstract
OBJECTIVE To evaluate the feasibility and efficacy of small-caliber transnasal esophagogastroduodenoscopy for the placement of nasoenteric feeding tubes (NET) in patients with severe upper gastrointestinal (GI) diseases. METHODS Between January 2007 and March 2010, 51 patients underwent transnasal endoscopy for the placement of NET in Peking University Third Hospital. Indications for NET included esophageal stricture or gastric outlet obstruction because of corrosive esophagitis or gastritis, partial obstruction due to malignancy, stenosis in stoma or efferent loop, gastroparesis, metallic stent in upper GI tract, tracheoesophageal fistula, severe acute pancreatitis, anorexia nervosa and intensive care patients. The tubes were endoscopically placed using the guidewire technique. The position of the tube was confirmed by the immediate second endoscopy or abdominal X-ray. If the initiate placement was not correct, an adjustment or a second placement was conducted immediately. RESULTS Initial post-pyloric placement of NET was achieved in 43 of 51 patients (84.3%), but the total success rate reached 98.0% (50/51) after the second placement. The time required for the procedure ranged from 10 to 35 min, with a median time of 20.4 min. Epistaxis occurred in 2 patients. There were no complications of hemorrhage, perforation or aspiration. CONCLUSION The transnasal endoscopic placement of NET was feasible in patients with upper GI diseases, especially in those with changed anatomy.

Abstract
OBJECTIVES/HYPOTHESIS Asymptomatic subjects volunteering for research studies are generally stratified as healthy based on a questionnaire, medical interviewing, and physical examination. The aim of this study was to evaluate the prevalence of upper gastrointestinal (GI) abnormalities in healthy asymptomatic volunteers using unsedated transnasal esophagogastroduodenoscopy (T-EGD) with an ultrathin endoscope as an additional screening tool. STUDY DESIGN A prospective study from one academic medical center with extensive experience in T-EGD. METHODS Consecutive 150 subjects volunteering for research studies were initially screened by using a gastroesophageal reflux disease (GERD) questionnaire, interviewing, and examination. Based on these, they were stratified as healthy asymptomatic volunteers or with GERD. Unsedated T-EGD was then performed by a faculty member who was blinded to the results of the initial assessment. RESULTS On initial assessment using GERD questionnaire, medical interviewing, and physical examination, of the total 150 consecutive research volunteers, 83 (average age 33 ± 16 years; 46 females, 37 males) subjects were healthy asymptomatic volunteers and 67 (average age 36 ± 15 years; 35 females, 32 males) had symptoms of GERD. On T-EGD, GI pathology was found in 15 of 83 (18%) healthy asymptomatic volunteers as compared to 24 of 67 (36%) stratified as having GERD (P < .01). The esophageal abnormalities found in healthy asymptomatic volunteers were esophagitis (13.3%), Barrett's esophagus (2.4%), hiatus hernia (2.4%), and gastritis (2.4%). CONCLUSIONS A small but significant number of asymptomatic subjects have abnormal upper GI findings. Hence, transnasal unsedated endoscopy can be considered as a screening tool to stratify subjects as healthy, especially when considering them for research studies.

Abstract
AIM To determine tolerance to fiber supplementation of semi-elemental tube feeds in critically ill patients and measure its effect on colonic microbiota and fermentation. METHODS Thirteen intensive care unit patients receiving jejunal feeding with a semi-elemental diet for predominantly necrotizing pancreatitis were studied. The study was divided into 2 parts: first, short-term (3-9 d) clinical tolerance and colonic fermentation as assessed by fecal short chain fatty acid (SCFA) concentrations and breath hydrogen and methane was measured in response to progressive fiber supplementation increasing from 4 g tid up to normal requirement levels of 8 g tid; second, 4 patients with diarrhea were studied for 2-5 wk with maximal supplementation to additionally assess its influence on fecal microbiota quantitated by quantitative polymerase chain reaction (qPCR) of microbial 16S rRNA genes and Human Intestinal Tract Chip (HITChip) microarray analysis. Nearly all patients were receiving antibiotics (10/13) and acid suppressants (11/13) at some stage during the studies. RESULTS In group 1, tolerance to progressive fiber supplementation was good with breath hydrogen and methane evidence (P = 0.008 and P < 0.0001, respectively) of increased fermentation with no exacerbation of abdominal symptoms and resolution of diarrhea in 2 of 4 patients. In group 2 before supplementation, fecal microbiota mass and their metabolites, SCFA, were dramatically lower in patients compared to healthy volunteers. From qPCR and HITChip analyses we calculated that there was a 97% reduction in the predominant potential butyrate producers and starch degraders. Following 2-5 wk of fiber supplementation there was a significant increase in fecal SCFA (acetate 28.4 ± 4.1 μmol/g to 42.5 ± 3.1 μmol/g dry weight, P = 0.01; propionate 1.6 ± 0.5 vs 6.22 ± 1.1, P = 0.006 and butyrate 2.5 ± 0.6 vs 5.9 ± 1.1, P = 0.04) and microbial counts of specific butyrate producers, with resolution of diarrhea in 3 of 4 patients. CONCLUSION Conventional management of critically ill patients, which includes the use of elemental diets and broad-spectrum antibiotics, was associated with gross suppression of the colonic microbiota and their production of essential colonic fuels, i.e., SCFA. Our investigations show that fiber supplementation of the feeds has the potential to improve microbiota mass and function, thereby reducing the risks of diarrhea due to dysbiosis.

Abstract
Introduction To accomplish early enteral feeding in the critically ill patient a new transnasal endoscopic approach to the placement of postpyloric feeding tubes by intensive care physicians was evaluated. Methods This was a prospective cohort study in 27 critically ill patients subjected to transnasal endoscopy and intubation of the pylorus. Attending intensive care physicians were trained in the handling of the new endoscope for transnasal gastroenteroscopy for two days. A jejunal feeding tube was advanced via the instrument channel and the correct position assessed by contrast radiography. The primary outcome measure was successful postpyloric placement of the tube. Secondary outcome measures were time needed for the placement, complications such as bleeding and formation of loops, and the score of the placement difficulty graded from 1 (easy) to 4 (difficult). Data are given as mean values and standard deviation. Results Out of 34 attempted jejunal tube placements, 28 tubes (82%) were placed correctly in the jejunum. The duration of the procedure was 28 ± 12 minutes. The difficulty of the tube placement was judged as follows: grade 1: 17 patients, grade 2: 8 patients, grade 3: 7 patients, grade 4: 2 patients. In three cases, the tube position was incorrect, and in another three cases, the procedure had to be aborted. In one patient bleeding occurred that required no further treatment. Conclusions Fast and reliable transnasal insertion of postpyloric feeding tubes can be accomplished by trained intensive care physicians at the bedside using the presented procedure. This new technique may facilitate early initiation of enteral feeding in intensive care patients.

Abstract
Nasogastric tubes are used in all specialties of medical practice. In critically ill patients, these feeding tubes provide enteral nutrition, which maintains enteric mucosal integrity as well as the immune system of the body, less risk of sepsis and decrease in length of intensive care stay. The insertion of nasogastric tube (NGT) is being considered as a simple blind bedside procedure but this procedure is not free of complications and can be fatal as these tubes can be malpositioned into the respiratory tract or central nervous system. Critically ill patients with endotracheal and tracheostomy tube are at particular risk for malpositioning of the nasogastric tubes due to loss of protective reflexes. Here we report three cases, two intubated and one patient with tracheostomy, in whom the enteral feeding tube was malpositioned into the respiratory system, detected early and a new one inserted in correct position, confirmed by x-ray. The aim of this report is to increase awareness about malpositioning of gastric feeding tubes, proper confirmation of their positioning, risk factors for malpositioning and its prevention.

Abstract
OBJECTIVES In critically ill patients, correct placement of enteral feeding tubes is usually controlled by X-ray. A bedside method without radiation exposure would be preferable. This study aimed to demonstrate the feasibility and value of endoscopic position control for enteral feeding tubes by transnasal re-endoscopy. METHODS A total of 120 consecutive examinations in critically ill patients were analyzed. Immediately after transnasal endoscopic placement of a feeding tube, the correct position was determined by re-endoscopy. In cases of incorrect position, replacement was performed instantly until the correct position was achieved. Abdominal X-ray with contrast was performed thereafter and served as the gold standard. RESULTS In 95 patients (79%), endoscopic control showed correct position. In 25 patients, position was incorrect and endoscopic placement was repeated (one attempt in 22 patients, two attempts in 3 patients). Radiological control showed correct position in 118 patients (98%). In two cases, the feeding tube was displaced in the meantime. The sensitivity and positive predictive value of endoscopic position control was 100% (95% confidence interval, CI; 97-100%) and 98% (95% CI; 94-99%), respectively. The cost savings per case ranged from $281 to $302, depending on different cost assumptions. CONCLUSIONS Endoscopic position control of enteral feeding tubes by re-endoscopy is feasible, very accurate, leads to a high rate of successful feeding tube placements, and has the potential of substantial cost-savings.

Abstract
The advent of total parenteral nutrition in the late 1960s meant that no situation remained in which a patient could not be fed. Unfortunately, total parenteral nutrition was complicated by serious infective and metabolic side effects that undermined the beneficial effects of nutrient repletion. Consequently, creative ways of restoring upper gut function were designed, based on semielemental diets and novel feeding tube systems. The employment of specific protocols and acceptance of increased gastric residual volumes has allowed most patients in intensive care to be fed safely and early by nasogastric tube. However, nasogastric feeding is unsuitable for patients with severely compromised gastric emptying owing to partial obstruction or ileus. Such patients require postpyloric tube placement with simultaneous gastric decompression via double-lumen nasogastric decompression and jejunal feeding tubes. These tubes can be placed endoscopically 40-60 cm past the ligament of Treitz to enable feeding without pancreatic stimulation. In patients whose disorders last more than 4 weeks, tubes should be repositioned percutaneously, by endoscopic, open or laparoscopic surgery. Together, the advances in enteral access have improved patients' outcomes and led to a 70-90% reduction in the demand for total parenteral nutrition.

Abstract
Transnasal esophagogastroduodenoscopy (TN-EGD) has recently become one of the frequently used methods of upper gastrointestinal endoscopy in some countries. Changes in blood pressure, heart rate, and oxygen saturation are smaller for TN-EGD than for conventional transoral esophagogastroduodenoscopy, making it a safer procedure. Lower pain and gag reflex enable TN-EGD to be performed without conscious sedation. TN-EGD is applied in various gastrointestinal (GI) procedures such as percutaneous endoscopic gastrostomy, nasoenteric feeding tube placement, endoscopic retrograde cholangiopancreaticography with nasobiliary drainage and lithotripsy, long intestinal tube placement in small-bowel obstruction, esophageal manometry, foreign body removal, botulinum toxin injection for achalasia, esophageal varix evaluation with the aid of endoscopic ultrasonography, and the double-scope technique for endoscopic submucosal dissection. The establishment of standard training programs and nationwide guidelines, the dissemination of educational information, the improvement in endoscopy devices and accessories, and the availability of insurance coverage for the procedure will obviously further widen the adoption of TN-EGD.

Abstract
Insertion of Ryles tube is a simple routine procedure. During its insertion, minor complications like trauma to nose, nasopharynx and oral cavity do happen from time to time. But as the Ryles tube is usually inserted blindly, potentially life threatening complications like inadvertent entry into trachea, cranial cavity and intravascular penetration have been reported. Folds and kinks may occur, but true knot of the Ryles tube, which we now report, is very rare.

Abstract
Nasogastric enteral feeding is not tolerated in patients with gastric atony and in many critically-ill patients in whom gastric emptying may be delayed and in whom gastro-oesophageal regurgitation may lead to pulmonary aspiration of enteral feed and the development of pneumonia. Initial attempts to overcome these problems led to the development of post pyloric enteral feeding techniques with the infusion port of the tubes positioned in the duodenum. In many centres this technique is still the most practised post-pyloric enteral feeding technique. Nasoduodenal feeding tubes often retroperistalse into the stomach. The technique of choice, therefore, in these difficult patients is to position the infusion port of the feeding tube well distal to the ligament of trietz (post ligament of trietz nasojejunal enteral tube feeding). While nasogastric and nasoduodenal enteral feeding techniques have been shown to elicit a stimulatory exocrine pancreatic response, distal jejunal enteral feeding does not. During this mode of feeding the ileal brake is activated and pancreatic exocrine pancreatic secretion inhibited by the action of the released peptide YY and glucagon-like peptide-1 hormones, in turn the inhibition of pancreatic secretion being the result of inhibition of trypsin secretion. In the light of the findings showing the absence of a stimulatory pancreatic exocrine response to nasojejunal enteral feeding these patients should receive a predigested rather than a polymeric enteral diet.

Abstract
BACKGROUND The technical difficulties related to the insertion of a long intestinal tube into the jejunum under fluoroscopy present a considerable problem in patients with an intestinal obstruction. OBJECTIVE To evaluate the usefulness of endoscopic long intestinal-tube placement with the ultrathin esophagogastroduodenoscope (UT-EGD). DESIGN A prospective randomized clinical trial was conducted. PATIENTS Twenty-eight consecutive patients who presented with an intestinal obstruction were included in the study. INTERVENTION The UT-EGD was inserted nasally into at least the second portion of the duodenum or beyond. After a guidewire was introduced through the working channel, with fluoroscopic guidance, the UT-EGD itself was carefully removed with the guidewire left in place. Next, a hydrophilic intestinal tube was advanced over the guidewire into the jejunum, and then the guidewire was removed. MAIN OUTCOME MEASUREMENTS Primary end points are the total procedure time, the radiation exposure time, and the rate of complications, all compared with the conventional method. RESULTS The mean (+/-SD) total procedure time was 18.7 +/- 8.4 minutes for the UT-EGD method and 39.5 +/- 15.0 minutes for the conventional method, with a significant time difference between the 2 methods (P < .0005). The mean (+/-SD) radiation exposure time was also shorter with the UT-EGD method (11.1 +/- 6.0 minutes) than with the conventional method (30.3 +/- 13.7 minutes) (P < .0005). There were no complications, except for mild nasal bleeding with each method. CONCLUSIONS The UT-EGD method has definite advantages in the placement of a long intestinal tube for patients with an intestinal obstruction in comparison with the conventional method.

Abstract
PURPOSE OF REVIEW This review explores the role of enteral and parenteral nutrition in severe acute pancreatitis and discusses the potential benefits of glutamine, omega-3 fatty acids, arginine and selenium together with probiotics and prebiotics in these patients. In addition, the method of refeeding during the convalescent period is also examined. RECENT FINDINGS A complex picture is emerging in which enteral nutritional support may be important early in the course of the disease with parenteral nutrition being used more as a backup and possibly only after the systemic inflammatory response has peaked. Nasogastric feeding, sometimes supplemented by parenteral nutrition, is as efficacious as nasojejunal feeding. An individualized approach, in which strategies of nutritional support are tailored to patient response, is gaining currency. Data regarding specialized formulae are mixed but the use of prebiotics is showing promise and is worthy of further exploration. In the convalescent period, preliminary data also indicate that the risk of pain developing is no greater if a light diet is instituted rather than clear fluids. SUMMARY Nutritional support in acute pancreatitis remains challenging and controversial with a number of different and unexpected approaches, including the use of nasogastric feeding and dual enteral and parenteral nutrition support, being adopted in recent clinical trials.

Abstract
BACKGROUND Transnasal endoscopy with a small-caliber endoscope has been shown to be helpful for the placement of nasoenteral feeding tubes in patients who are critically ill. Success rates were limited by the short working length of the small-caliber endoscopes. OBJECTIVE To compare the success rate of a 133-cm-long, small-caliber, prototype videoendoscope with a standard 92-cm-long, small-caliber, fiberoptic endoscope for the transnasal placement of feeding tubes. DESIGN Randomized controlled study. SETTING University Hospital of Zurich, Switzerland. PATIENTS Patients who were critically ill were randomly assigned to transnasal feeding tube placement with the standard 92-cm-long, small-caliber, fiberoptic endoscope, or with a new 133-cm-long, small-caliber, prototype videoendoscope. Patient characteristics, procedure time, technical difficulties, patient tolerance, and radiologic tube position were assessed. MAIN OUTCOME MEASUREMENTS Success rates of endoscopic placement of enteral feeding tubes. RESULTS A total of 157 patients were analyzed in 2 groups. The 2 groups were similar with regard to patient characteristics, body length, technical difficulty, and patient tolerance. The 133-cm-long instrument was superior with respect to successful placement of the nasoenteral feeding tube (93.6% vs 74.4%, P = .0008). Patient tolerance, procedure times, and overall technical difficulty were the same in both treatment groups, whereas passage through the duodenum was more difficult with the 133-cm-long instrument (P < .0001). LIMITATIONS In rare cases, the randomization list could not be followed correctly. CONCLUSIONS This study demonstrated that placement of a nasoenteral feeding tube with a 133-cm-long, small-caliber videoendoscope is feasible, safe, and distinctly more successful than with a 92-cm-long, small-caliber standard instrument.

Abstract
Despite the great advances in our understanding of the pathophysiology of acute pancreatitis, no specific therapy has emerged, and treatment remains supportive. In patients with the severe form of the disease, in which mortality remains high at 20% to 30%, the function of the upper gastrointestinal tract is disturbed due to extrinsic compression by the inflamed and swollen pancreas, and normal eating is impossible. Such patients often develop multiple organ failure, necessitating intensive-care management and artificial ventilation for weeks on end. In this setting, protein catabolism will rapidly result in protein deficiency and further complications unless nutritional support is commenced. Recent studies have shown that, despite the risk of disease exacerbation through pancreatic stimulation, enteral feeding is more effective than parenteral feeding in improving outcome. Experimental studies suggest that this can be attributed to its content of specific immunomodulating nutrients, such as glutamine, arginine, and n-3 fatty acids, and by its stabilizing effect on the gut flora through the provision of prebiotics. Further studies are indicated to examine whether dietary enrichment with these substrates, along with regulation of the gut bacteria with probiotics, can improve outcome further.

Abstract
Nutritional support can improve the outcome from severe acute pancreatitis in two ways: first by providing the building blocks for tissue repair and recovery, and second, by modulating the inflammatory response and preventing organ failure, both of which are responsible for most of the morbidity and mortality associated with the disease. This review discusses the evidence on which these statements are based.

Abstract
The aim of this study was to prospectively analyze the possible association of delayed gastric emptying and postoperative pancreatic complications after pancreaticoduodenectomy. Although hospital mortality after pancreaticoduodenectomy is minimal, morbidity is still high; delayed gastric emptying is one of the most frequent complications. Thirty-nine consecutive patients undergoing pancreaticoduodenectomy were included in this study: 14 females and 25 males (median age 65 years; range, 7-82). Delayed gastric emptying was defined as the need for a nasogastric tube or recurrent vomiting that prevented normal feeding on the 10th postoperative day. Blood analysis was performed on postoperative days 4, 6, and 10; Gastrografin examination on day 6; CT scan on days 2 and 5; and drain amylases were measured on day 5. Pancreatitis was defined as pancreatitis changes in CT scan interpreted by an experienced radiologist without knowing other data. Pancreatic fistula was defined according to the recent international recommendations. We had no mortality. Twelve patients (31%) developed delayed gastric emptying. Surgical (9/12 vs. 5/27; P = 0.001) but not medical complications occurred more often in the delayed gastric emptying group. Of the single complications, postoperative CT-detected pancreatitis (6/12 vs. 4/27; P = 0.03) and postoperative pancreatic fistula (5/12 vs. 1/27; P = 0.0007) were significantly associated with delayed gastric emptying compared with the patients without delayed gastric emptying. This pancreatitis was already detected in CT scan on day 2 in most patients (6/10, 60%). In delayed gastric emptying patients, the only parameters in blood analysis that differed significantly from patients without this complication were serum amylase activity (mean +/- SEM, 715 +/- 205 vs. 152 +/- 70 IU/L; P = 0.02), blood leukocyte count (16 +/- 2 vs. 9 +/- 0.6 x 10(9)/L; P = 0.007) and serum C-reactive protein (CRP) concentration (144 +/- 28 vs. 51 +/- 14 mg/L, P = 0.01). Postoperative pancreatic (subclinical) fistula was also associated with postoperative pancreatitis (6/10 vs. 0/29; P = 0.003). Preoperative coronary artery disease (OR = 16; 95% CI, 1.0-241; P = 0.05) and soft pancreatic texture at operation (OR = 9; 95% CI, 1.4-52; P = 0.02) were significant risk factors for the development of postoperative pancreatitis. The diagnosis of delayed gastric emptying after pancreaticoduodenectomy often follows postoperative pancreatitis. Delayed gastric emptying is also associated with postoperative pancreatic fistula, for which this pancreatitis seems to be a risk factor. Preoperative coronary artery disease and soft texture of the pancreas are significant risk factors for postoperative CT-detected pancreatitis.

Abstract
PURPOSE OF REVIEW Normal digestive physiology is a highly orchestrated process, integrating the mechanical breakdown of food, the secretion of digestive juices, the control of motility, and the efficient absorption of nutrients. As enteral and parenteral feeding techniques bypass many of these control mechanisms, nutritional utilization can be expected to be disturbed. This review examines recent publications that have investigated this question in clinical practice. RECENT FINDINGS Studies in healthy volunteers have shown that all forms of oral and enteral tube feeds commonly used, including proximal jejunal elemental diets, stimulate pancreatic secretion. Avoidance of the cephalic phase with duodenal feeding does not reduce the secretory response. 'Pancreatic rest' can, however, be achieved if feeding is delivered 40-60 cm past the ligament of Treitz by activating the ileal brake, or if it is given intravenously by avoiding intestinal cholecystokinin stimulation and the cholinergic reflex. These forms of feeding, however, can cause complications as they will result in malabsorption unless elemental formulae are used, and hyperglycemia as the metabolic utilization of intravenous nutrients is impaired. SUMMARY An understanding of normal pancreatic physiology and how interventional feeding techniques affect it will help prevent complications and improve outcome in hospitalized patients.

Abstract
PURPOSE OF REVIEW Critical to realizing increasing benefits of enteral nutrition are techniques for feeding tube placement. Feeding tubes can be placed by bedside, endoscopic, fluoroscopic, and surgical methods. This review encompasses noteworthy studies on endoscopic approaches to enteral feeding published from January 2005 to the present. RECENT FINDINGS Studies involving placement of nasoenteric feeding tubes include description of new methods for endoscopic nasoenteric feeding tube placement using a push technique with a stiffened tube, a modification of the 'drag and pull' method using a distal suture tie, and placement using an ultrathin transnasal endoscopic technique compared with fluoroscopic placement. Recent studies involving percutaneous endoscopic gastrostomy tube placement have demonstrated equivalent outcomes of endoscopic and fluoroscopic approaches, description of unsedated placement using transnasal technique, and risk of percutaneous endoscopic gastrostomy site metastasis in head and neck cancer patients. Studies on percutaneous jejunal feeding tubes demonstrate: high complication rate and short functional duration of percutaneous endoscopic gastrojejunostomy and reported outcomes of direct percutaneous endoscopic jejunostomy placement. SUMMARY Enteral nutrition access can be obtained by a variety of methods depending on local expertise and resources. Endoscopic approaches have equivalent or better outcomes than other methods; however, these methods may still have limitations and distinct complications.

Abstract
PURPOSE OF REVIEW Enteral nutrition is the preferred route for nutrition support in the intensive care unit setting. This is usually delivered through nasoenteric feeding tubes in patients with an otherwise functional gastrointestinal tract. Placement of nasoenteric feeding tubes, however, may be difficult in this setting. Nasoenteric feeding tubes may be placed by multiple methods, each with their particular advantages and disadvantages. This review summarizes the recent literature on different methods of nasoenteric feeding tube placement with emphasis on critically ill patients. RECENT FINDINGS Bedside assisted methods using electromyogram, electrocardiogram, and magnetic fields to provide immediate positional feedback to help guide tube advancement appear promising. Bedside methods using specific protocols, modified feeding tubes, prokinetics or magnetic assistance were also successfully reported. None of these methods has been prospectively compared with more commonly practiced methods in large studies. Endoscopic nasoenteric tube placement methods including transnasal approaches using ultra-thin endoscopes have been recently described and appear to be equivalent to fluoroscopic placement. All these recently reported techniques, however, may require more specialized equipment or training than is currently widely available. SUMMARY Feeding tubes can be placed using bedside, fluoroscopic, and endoscopic means. Novel bedside methods have been recently described using immediate positional feedback or new assistive methods. Endoscopic techniques have similar success rates to fluoroscopic techniques and provide data on upper gastrointestinal abnormalities. There is no clear universal standard method. When feeding tube placement is required the technique used depends on local institutional resources and expertise.

Abstract
Knowledge of the stimulatory effects of enteral and parenteral (intravenous) feeding on the synthesis and turnover of trypsin would help in the management of acute pancreatitis, because the disease is caused by the premature activation of trypsin. To investigate this, we labeled intravenous infusions with [1-(13)C]leucine and enterals with [(2)H]leucine and measured isotope enrichment of plasma, secreted trypsin, and duodenal mucosal proteins over 6 h by duodenal perfusion/aspiration and endoscopic biopsy. Thirty healthy volunteers were studied during fasting (n = 7), intravenous feeding (n = 6), or postpyloric enteral feeding [duodenal polymeric (n = 6), elemental duodenal (n = 6), and jejunal elemental (n = 5)]. All diets provided 1.5 g x kg(-1) x day(-1) protein and 40 kcal x kg(-1) x day(-1) energy. Results demonstrated that compared with fasting, enteral feeding increased the rate of appearance (71 +/- 4 vs. 91 +/- 5 min, P = 0.01) and secretion (546 +/- 80 vs. 219 +/- 37 U/h, P = 0.01) of newly labeled trypsin and expanded zymogen stores (1,660 +/- 237 vs. 749 +/- 133 units, P = 0.03). These differences persisted whether the feedings were polymeric or elemental, duodenal, or jejunal. In contrast, intravenous feeding had no effect on basal rates. Differential labeling of the plasma amino acid pool by enteral and intravenous isotope infusions suggested that 35% of absorbed amino acids were retained within the splanchnic bed during enteral feeding and that mucosal protein turnover increased from a fasting rate of 34 +/- 6 to 108 +/- 8%/day (P < 0.05) compared with no change after intravenous feeding. In conclusion, all common forms of enteral feeding stimulate the synthesis and secretion of pancreatic trypsin, and only parenteral nutrition avoids it.

Abstract
BACKGROUND Placement of a nasoenteric feeding tube (NET) beyond the pylorus in critically ill patients is desirable. Bedside methods are unreliable, and fluoroscopic methods require transport and/or radiation exposure. Traditional endoscopic methods require sedation and oronasal transfer techniques. Transnasal techniques of NET placement by using recently developed ultrathin endoscopes have been described. The object of this prospective study was to compare the efficacy of NET placement by using ultrathin transnasal endoscopy vs. fluoroscopic placement. METHODS This is a prospective randomized study of endoscopic vs. fluoroscopic NET placement. The settings of the study were intensive care units at academic medical center. The study included 100 consecutive patients who required NET placement. They received endoscopic NET placement at the bedside with a 5.1-mm, ultrathin endoscope by using a transnasal over-the-wire technique vs. fluoroscopic NET placement by using standard techniques. The procedure success was defined as postpyloric (beyond the duodenal bulb) NET placement, jejunal placement success, and procedure time. RESULTS Tube placement success was not significantly different between endoscopic and fluoroscopic methods (90% with both methods; p = 1.00). The endoscopic procedure duration (12.8 +/- 6.4 minutes) was significantly shorter than fluoroscopic procedure duration (19.3 +/- 12.0 minutes) (p < 0.001). Procedure duration decreased significantly (from 17.3 +/- 6.2 minutes to 8.0 minutes +/- 4.2 minutes, p = 0.04), and jejunal placement increased significantly (from 60% to 100%, p = 0.04) from the first to the last 10 endoscopic procedures. CONCLUSIONS NET placement success with an ultrathin transnasal endoscope is equivalent to fluoroscopic placement with faster procedure times. More distal placement and procedure times improve with increasing experience with the endoscopic technique. Endoscopic NET placement can be performed at the bedside without the need for oronasal transfer, additional sedation, or fluoroscopy.

Abstract
Delivery of enteral nutrition in critically ill patients is often hampered by gastric stasis necessitating direct feeding into the small intestine. Current techniques for placement of post-pyloric feeding catheters are complex, time consuming or both, and improvements in feeding tube placement techniques are required. The Cathlocator is a novel device that permits real time localisation of the end of feeding tubes via detection of a magnetic field generated by a small electric current in a coil incorporated in the tip of the tube. We performed a pilot study evaluating the feasibility of the Cathlocator system to guide and evaluate the placement of (1) nasoduodenal feeding tubes, and (2) nasogastric drainage tubes in critically ill patients with feed intolerance due to slow gastric emptying. A prospective study of eight critically ill patients was undertaken in the intensive care unit of a tertiary hospital. The Cathlocator was used to (1) guide the positioning of the tubes post-pylorically and (2) determine whether nasogastric and nasoduodenal tubes were placed correctly. Tube tip position was compared with data obtained by radiology. Data are expressed as median (range). Duodenal tube placement was successful in 7 of 8 patients (insertion time 12.6 min (5.3-34.4)). All nasogastric tube placements were successful (insertion time 3.4 min (0.6-10.0)). The Cathlocator accurately determined the position of both tubes without complication in all cases. The Cathlocator allows placement and location of an enteral feeding tube in real time in critically ill patients with slow gastric emptying. These findings warrant further studies into the application of this technique for placement of post-pyloric feeding tubes.

Abstract
Studies in humans have shown that pancreatic enzyme secretion is reduced during acute pancreatitis. It is not known, however, whether the reduction is due to impaired synthesis or disruption of the secretory pathway. The rate of secretion and turnover of trypsin was measured in 12 patients with acute pancreatitis of variable etiology and severity (median Ranson's score 2.5, range 0-5, 4 with severe necrotizing disease) and eight healthy volunteers by 4-h primed/continuous intravenous infusions of 1-(13)C-labeled l-leucine, and collection of pancreatic secretions by duodenal perfusion and sampling. Trypsin secretion was reduced from 476 +/- 73 to 153 +/- 60 U/h (means +/- SE, P = 0.005) in acute pancreatitis, with the greatest reductions being observed in patients with necrotizing disease (32 +/- 7 U/h, P = 0.003). The time for newly labeled trypsin to first appear in digestive juice was not, however, delayed in pancreatitis patients (87.2 +/- 11.1 vs. 94.7 +/- 4.9 min); on the contrary, there was an early appearance of newly labeled trypsin at 30 min in patients with severe necrotizing pancreatitis (P < 0.05). Calculated zymogen pool turnover was unchanged, but pool size was decreased (P = 0.01). Despite low rates of luminal secretion, trypsin continues to be synthesized in patients with acute pancreatitis. Our findings could be explained by post-Golgi leakage of enzymes from acinar cells or by loss of synthetic function in some cells with preservation in others.
