Abstract
In this study, we investigated placement rate, complication rate and time spent of successful post-pyloric enteral feeding (PPEF) tube insertion procedure guided by ultrasonography (USG). The patients who required enteral nutrition and who admitted to medical intensive care unit (MICU) of Gazi University Hospital were included to this single-center, prospective, cohort study. It was aimed to insert the enteral feeding tube into the proximal duodenum as the post-pyloric area by ultrasonography guidance. During the PPEF tube insertion procedure, the linear probe was used to display the proximal esophagus and the convex probe was used to display the post-pyloric area, antrum and pyloric channel. 33 patients were included in this study. The median age was 68 [IQR 52-79] years. There were 17 (51.5%) woman and 22 (66.7%) intubated patients. The enteral feeding tube was successfully passed into the post-pyloric area in 29 (87.9%) patients with this technique. The median time of successful feeding tube insertion was 14 [IQR 10-25] min. The median level of the enteral feeding tube was 74 [IQR 70-76] cm. in successful placement. There was no significant difference in insertion time according to gender (female vs male; 10 [IQR 8-20] min. vs 17 [IQR 12-25] min., p = 0.052) and endotracheal intubation status (intubated vs non-intubated; 14 [IQR 10-25] min. vs 12 [IQR 10-25] min., p = 0.985). Only one complication was seen during study (self-limiting epistaxis in one patient). PPEF tube insertion under USG guidance could ensure the initiation of enteral feeding safely and rapidly without exposure to radiation in ICU patients.

Abstract
The commercial and biobased polyurethane foams (PUF) were produced and characterized in this study. Commercial polyether polyol, crude glycerol, methanol-free crude glycerol, and pure glycerol were used as polyols. Crude glycerol is byproduct of the biodiesel production, and it is a kind of biofuel residue. Polyol blends were prepared by mixing the glycerol types and the commercial polyol with different amounts, 10 wt%, 30 wt%, 50 wt%, and 80 wt%. All types of polyol blends were reacted with polymeric diphenyl methane diisocyanates (PMDI) for the production of rigid foams. Thermal properties of polyurethane foams are examined by thermogravimetric analysis (TGA) and thermal conductivity tests. The structures of polyurethane foams were examined by Fourier Transformed Infrared Spectroscopy (FTIR). Changes in morphology of foams were investigated by Scanning Electron Microscopy (SEM). Mechanical properties of polyurethane foams were determined by compression tests. This study identifies the critical aspects of polyurethane foam formation by the use of various polyols and furthermore offers new uses of crude glycerol and methanol-free crude glycerol which are byproducts of biodiesel industry.

Abstract
BACKGROUND The importance of early postoperative nutrition in surgical patients and early institution of enteral nutrition in intensive care unit (ICU) patients have recently been highlighted. Unfortunately, institution of enteral feeding in both groups of patients often has to be postponed due to delayed gastric emptying and the need for gastric decompression. The design of current polyvinylchloride (PVC) gastric decompression tubes (Salem Sump [Covidien, Mansfield, MA] in the United States; Ryles [Penine Health Care Ltd, Derby, UK] in the United Kingdom and Europe) make them unsuitable for their subsequent use as either nasogastric enteral feeding tubes or for continued gastric decompression during postpyloric enteral feeding. To overcome these problems, we have designed a range of polyurethane (PU) dual-purpose gastric decompression and enteral feeding tubes that include 2 nasogastric tubes (double lumen to replace Salem Sump; single lumen to replace Ryles). Two novel multilumen nasogastrojejunal tubes (triple lumen for the United States; double lumen for the United Kingdom and Europe) complete the range. By using PU, a given internal diameter (ID) and flow area can be incorporated into a lower outside diameter (OD) compared with that achieved with PVC. The ID and lumen and flow area of an 18Fr (OD 6.7 mm) PVC Salem Sump can be incorporated into a 14Fr (OD 4.7 mm) PU tube. The design of aspiration/infusion ports of current PVC and PU tubes invites occlusion by gastrointestinal mucosa and clogging by mucus and enteral feed. To overcome this, we have designed long, single, widened, smooth, and curved edge ports with no "dead space" to trap mucus or curdled diet. Involving up to 214° of the circumference, these ports have up to 11 times the flow areas of the aspiration ports of current PVC tubes. CONCLUSION The proposed designs will lead to the development of dual-purpose nasogastric and nasojejunal tubes that will significantly improve the clinical and nutrition care of postoperative and ICU patients.

Abstract
Background Enteral tubes are frequently inserted as part of medical treatment in a wide range of patient situations. Patients with an enteral tube are cared for by nurses in a variety of settings, including general and specialised acute care areas, aged care facilities and at home. Regardless of the setting, nurses have the primary responsibility for administering medication through enteral tubes. Medication administration via an enteral tube is a reasonably common nursing intervention that entails a number of skills, including preparing the medication, verifying the tube position, flushing the tube and assessing for potential complications. If medications are not given effectively through an enteral tube, harmful consequences may result leading to increased morbidity, for example, tube occlusion, diarrhoea and aspiration pneumonia. There are resultant costs for the health-care system related to possible increased length of stay and increased use of equipment. Presently what is considered to be best practice to give medications through enteral tubes is unknown. Objectives The objective of this systematic review was to determine the best available evidence on which nursing interventions are effective in minimising the complications associated with the administration of medications via enteral tubes in adults. Nursing interventions and considerations related to medication administration included form of medication, verifying tube placement before administration, methods used to give medication, methods used to flush tubes, maintenance of tube patency and specific practices to prevent possible complications related to the administration of enteral medications. Search strategy The following databases were searched for literature reported in English only: CINAHL, MEDLINE, The Cochrane Library, Current Contents/All Editions, EMBASE, Australasian Medical Index and PsychINFO. There was no date restriction applied. In addition, the reference lists of all included studies were scrutinised for other potentially relevant studies. Selection criteria Systematic reviews of randomised controlled trials (RCTs) and RCTs that compared the effectiveness of nursing interventions and considerations used in the administration of medications via enteral tubes. Other research methods, such as non-randomised controlled trials, longitudinal studies, cohort and case control studies, were also included. Exclusion criteria included studies investigating drug-nutrient interactions or the bioavailability of specific medications. Data collection and analysis Initial consideration of potential relevance to the review was carried out by the primary author (NP). Two reviewers independently assessed study eligibility for inclusion. A meta-analysis could not be undertaken, as there were no comparable RCTs identified. All data were presented in a narrative summary. Results There is very limited evidence regarding the effectiveness of nursing interventions in minimising the complications associated with enteral tube medication administration in adults. The review highlights a lack of high quality research on many important nursing issues relating to enteral medication administration. There is huge scope for further research. Some of the evidence that was identified included that nurses should consider the use of liquid form medications as there may be fewer tube occlusions than with solid forms in nasoenteral tubes and silicone percutaneous endoscopic gastronomy tubes. Nurses may need to consider the sorbitol content of some liquid medications, for example, elixirs, as diarrhoea has been attributed to the sorbitol content of the elixir, not the drug itself. In addition, the use of 30 mL of water for irrigation when administering medications or flushing small-diameter nasoenteral tubes may reduce the number of tube occlusions.

Abstract
The ASGE Technology Committee provides reviews of existing, new, or emerging endoscopic technologies that have an impact on the practice of GI endoscopy. Evidence-based methodology is used, performing a MEDLINE literature search to identify pertinent clinical studies on the topic and a MAUDE (U.S. Food and Drug Administration Center for Devices and Radiological Health) database search to identify the reported complications of a given technology. Both are supplemented by accessing the "related articles" feature of PubMed and by scrutinizing pertinent references cited by the identified studies. Controlled clinical trials are emphasized, but, in many cases, data from randomized, controlled trials are lacking. In such situations, large case series, preliminary clinical studies, and expert opinions are used. Technical data are gathered from traditional and Web-based publications, proprietary publications, and informal communications with pertinent vendors. Technology Status Evaluation Reports are drafted by 1 or 2 members of the ASGE Technology Committee, reviewed and edited by the committee as a whole, and approved by the ASGE Governing Board. When financial guidance is indicated, the most recent coding data and list prices at the time of publication are provided. For this review, the MEDLINE database was searched through August 2009 for articles related to endoscopy in patients requiring enteral feeding access by using the keywords "endoscopy," "percutaneous," "gastrostomy," "jejunostomy," "nasogastric," "nasoenteric," "nasojejunal," "transnasal," "feeding tube," "enteric," and "button." Technology Status Evaluation Reports are scientific reviews provided solely for educational and informational purposes. Technology Status Evaluation Reports are not rules and should not be construed as establishing a legal standard of care or as encouraging, advocating, requiring, or discouraging any particular treatment or payment for such treatment.

Abstract
BACKGROUND The early institution of feeding in patients who need postpyloric feeding tubes is often hampered by a limited availability of endoscopists experienced in safe tube positioning. OBJECTIVE To test the feasibility of having nurses place postpyloric feeding tubes by using a universal path finding system device. DESIGN Prospective study. SETTING Academic hospital. PATIENTS The success rate and learning curve of a senior nurse placing postpyloric feeding tubes in 50 patients was studied, followed by a study in 160 patients on the success rates and learning curves of 4 inexperienced nurses instructed by the senior nurse. Finally, the success rate of postpyloric feeding tube placement by the senior nurse in 50 critically ill patients was investigated. INTERVENTION Postpyloric feeding tube positioning by nurses using an electromagnetic universal path-finding system device enabling them to follow the path of the tip of the feeding tube on a monitor screen. MAIN OUTCOME MEASUREMENTS Success was defined by postpyloric positioning of the feeding tube. The ultimate aim was to reach at least the duodenojejunal flexure. RESULTS In the first part, the senior nurse was successful in 72% of cases. There was a clear learning curve. In the second part, the 4 newly instructed nurses had a success rate of 89.4% without an evident learning curve. In the third part, successful feeding tube positioning was achieved in 78% of critically ill patients. Of the 217 successfully positioned tubes, 74% reached at least the duodenojejunal flexure. In half of the unsuccessful cases, an explanation for the failure was found at endoscopy. No complications were seen. LIMITATIONS The generalization to less-specialized hospitals should be investigated. CONCLUSION Postpyloric positioning of feeding tubes by nurses at the bedside without endoscopy is feasible and safe. Nurses may take over some of the tasks of doctors in a time of high endoscopic needs.

Abstract
AIM This systematic review aimed to determine the best available evidence regarding the effectiveness of nursing interventions in minimising the complications associated with administering medication via enteral tubes in adults. BACKGROUND Giving enteral medication is a fairly common nursing intervention entailing several skills: verifying tube position, preparing medication, flushing the tube and assessing for potential complications. If not carried out effectively harmful consequences may result leading to increased morbidity and even mortality. Until now, what was considered to be best practice in this area was unknown. DESIGN Systematic review. METHODS CINAHL, MEDLINE, The Cochrane Library, Current Contents/All Editions, EMBASE, Australasian Medical Index and PsychINFO databases were searched up to September 2005. Reference lists of included studies were appraised. Two reviewers independently assessed study eligibility for inclusion. There were no comparable randomised-controlled trials; data were presented in a narrative summary. RESULTS Identified evidence included using 30 ml of water for irrigation when giving medication or flushing small-diameter nasoenteral tubes may reduce tube occlusion. Using liquid medication should be considered as there may be less tube occlusions than with solid forms in nasoenteral tubes and silicone percutaneous endoscopic gastrostomy tubes. In addition, nurses may need to consider the sorbitol content of some liquid medications, for example elixirs, as diarrhoea has been attributed to the sorbitol content of the elixir, not the drug itself. CONCLUSION The evidence was limited. There was a lack of high-quality research on many important issues relating to giving enteral medication. RELEVANCE TO CLINICAL PRACTICE Nurses have the primary responsibility for giving medication through enteral tubes and need knowledge of the best available evidence. Some of the nursing considerations and interventions relating to this skill have been researched in the clinical area and have implications for practice. There is a need for further studies to strengthen these findings.

Abstract
Concerned with reports in the literature of a rising incidence of enteral feeding tube clogging, we initiated a design programme in an attempt to improve the clinical efficacy of nasogastric and nasoenteric enteral feeding tubes. Tube design has been based on a remodelling of the outflow part of a polyurethane feeding tube previously developed in our unit. The tip of the newly designed 8F enteral feeding tube is shorter in length with a rounded end to minimize discomfort during intubation. The port itself incorporates a tapered outflow design with the side walls now extending below the mid-point of the internal flow lumen resulting in a 28% increase in port area compared to the equivalent and originally designed tube. The performance of the newly designed polyurethane feeding tube was assessed under controlled trial conditions using as references two widely used 8F polyurethane nasogastric feeding tubes whose design has been based on different principles (Flexiflo, weighted tip, open-ended with two side ports; Freka, occluded tip, two simple large side ports). Eighty-eight of 90 patients entered into the study were successfully intubated with no significant differences being noted in intubation times in the three groups. Significantly less discomfort occurred during intubation of patients with the Radius tube as compared to the Freka tube (P < 0.05). Although there were no clear differences between the Flexiflo and Freka tubes either in regard to the number of attempts required for intubation or aspiration or discomfort during intubation or ease of aspiration, fewer attempts at insertion and aspiration were needed and intubation and aspiration were easier for patients randomised to the Radius group than those to the Flexiflo and Freka groups (P < 0.05). We conclude that the clinical performance of the newly designed Radius enteral feeding tube compares favourably with that of the reference tubes. Only one of the new tubes (3.3%) blocked during the course of the study. High rates of non-elective extubation were observed in the three study groups (Radius 80.0%, Flexiflo 73.3%, Freka 73.3%). Design modifications are unlikely to influence non-elective nasogastric feeding tube extubation rates which remain a major clinical problem.

Abstract
BACKGROUND Patients with esophageal cancer often present with dysphagia and malnutrition. Obstructive symptoms may improve after radiotherapy and chemotherapy. Nutrition support via a nasogastric tube (NG) or gastrostomy is very important during treatment. The newly developed ultrathin endoscope (Olympus, GIF-N230, outer diameter: 6 mm) has a smaller diameter than the standard endoscope and can be introduced into the esophagus via the nasal cavity. This article reports on the use of an ultrathin endoscope for NG placement for patients with esophageal cancer who presented with dysphagia and failed traditional NG tube placement. METHODS A consecutive series of 40 patients with esophageal cancer were referred to our hospital from November 2001 to October 2002 for endoscopic placement of NG tubes due to failure of traditional methods of NG placement. An ultrathin endoscope was used to advance the guidewire into the stomach via the nasal cavity. After withdrawal of the scope, the NG tube was inserted over the guidewire under fluoroscopy. OBSERVATIONS A total of 71 procedures were performed in 40 patients (37 males, 3 females), age 57 +/- 15 years (range, 37-91 y). Seventy procedures (99%) were successful in completing NG tube placement by using an ultrathin transnasal endoscope. Only one procedure failed because the esophageal lumen was completely occluded and the guidewire was not able to be passed through the obstructed site. The average duration that the NG tube was left in place was 49 +/- 35 days (range, 2-144 days). No procedure-related complications, such as bleeding or perforation, occurred. CONCLUSIONS Using ultrathin transnasal endoscopy to place an NG tube for esophageal cancer patients is effective and safe. It simplifies the procedures and increases the success rate.

Abstract
Optimal management of the critically ill patient involves the initiation and rapid advancement of early enteral nutrition (EN). Compared to parenteral nutrition or no nutritional support, early enteral feeding favorably impacts patient outcome by reducing infectious morbidity and shortening hospital length of stay. Controversy exists over the true risks and benefits of pre-pyloric versus post-pyloric feeding. Placement of nasogastric tubes is easier than nasojejunal tubes, initiation of EN is more expedient, and intragastric feeds may provide greater physiologic benefits. Post-pyloric feeding, on the other hand, is associated with fewer interruptions once EN has been started, may reach goal calorie provision sooner, and may reduce risk for gastroesophageal reflux and aspiration. Overall differences in outcome between the two methods of feeding, however, are minimal. Thus, the final choice for the practicing clinician on the level of infusion of enteral feeding is based on institutional factors (related to protocols and available expertise) and the degree of risk and potential tolerance of the individual patient.

Abstract
The provision and maintenance of good nutrition in patients with acute and chronic illness is a fundamental part of standard medical and surgical care. Recently, there is great interest in using enteral nutritional support to reverse the morbidity and mortality associated with malnutrition. Enteral nutrition is preferred over parenteral nutrition because it is more physiologic, maintains intestinal structure and function, limits bacterial translocation, has less morbidity, has fewer complications, and is less expensive. However, the decision to feed into the stomach or into the small bowel (postpyloric) continues to be a matter of some debate and continued clinical investigation. Although the gastric route of enteral feeding is easier and less expensive, some physicians worry that gastric feeding may predispose to aspiration and pneumonia, especially in critically ill patients who frequently have delayed gastric transit. In these critically ill patients, small bowel function usually remains relatively intact and placement of a postpyloric feeding tube may permit more effective delivery of nutrients. However, it should be noted that placement of postpyloric feeding tubes can be challenging, and this may lead to a delay in initiation of nutritional support.

Abstract
Acquisition of enteral access and provision of a sufficient volume of enteral nutrients early in the hospital course of a critically ill patient afford an opportunity to improve the outcome of that patient through the progression of his or her disease process. Failure to use the enteral route of feeding not only squanders this opportunity, but may, in addition, promote a pro-inflammatory state, which exacerbates disease severity and worsens morbidity. Enteral feeding provides a conduit for the delivery of immune stimulants and serves as effective prophylaxis against stress-induced gastropathy and gastrointestinal hemorrhage. Tube placement beyond the stomach into the small bowel in hypermetabolic, severely ill patients prone to ileus and disordered gut motility aids delivery of enteral nutrients while reducing risk of aspiration. Endoscopic skills and expertise in gastrointestinal physiology are vital to the success of a nutrition support service and the provision of enteral tube feeding.

Abstract
When making decisions regarding nutrition support, many factors must be considered before committing a patient to receive parenteral or enteral nutrition. Parenteral nutrition (PN) is more expensive and technically more difficult to administer than enteral nutrition (EN). The charge for PN can range from US 200 dollars to 1000 dollars per day, where a standard hospital diet or enteral tube feedings might cost less than US 25 dollars/d. PN is also associated with a much higher incidence of biochemical complications such as hyperglycemia and other electrolyte abnormalities and catheter-related complications such as infection, thrombosis, or pneumothorax. For many years PN was preferred to EN because it was believed to be unwise to feed a critically ill patient into the gut. It has now been shown in multiple studies that it is not only feasible to feed critically ill patients early, but also it may be immunologically advantageous to feed enterally. The cost effectiveness of the nutrition support team approach to monitoring PN and EN should not be underestimated by hospital administrators. If enteral therapy can be instituted, significant patient-care cost savings may be realized. This presentation will discuss decisions that must be addressed in the intensive care unit. With more physician education, protocols can be designed to provide the most advantageous use of nutrition support for the benefit of the hospitalized patient.

Abstract
The use of nutrition for the medical patient, in the inpatient setting and at home, will likely continue to increase in the future. Each patient should be evaluated in an individualized but systematic fashion. Each patient in whom malnourishment is suspected should undergo a thorough assessment for the presence and degree of malnutrition with an accurate calculation of nutritional requirements. It is important to choose the correct method of delivery of nutrition, to monitor and recognize any complications or problems that may arise, and to tailor the nutritional therapy to the unique diseases that are encountered in medicine. Although increasingly new advances and changes are occurring in the field of nutrition, nutritional support and therapy are best delivered and supplied to the patient with a network of health care workers, including the physician, the nurse, the dietitian, the social worker, and pharmacist.

Abstract
BACKGROUND Spontaneous transpyloric migration of a simple nasojejunal tube (NJT) can be expected in only one-third of insertions. Guidance of the tube by radiologic or endoscopic maneuvers is usually required. We believed that locating a 5-mL balloon near the tip of an NJT on which natural peristalsis could act would improve the rate of spontaneous transpyloric migration and facilitate small bowel propagation. METHODS Thirty healthy volunteers were randomly assigned to have an inflated or noninflated, ballooned NJT fashioned from a modified 9F Hickman line catheter inserted. The pH of aspirates was measured hourly and the final location of the tube assessed by gastrografin contrast abdominal x-ray (AXR) at the end of 6 hours, at which time the tube was removed. RESULTS After 6 hours, spontaneous transpyloric migration occurred in 86.6% of the ballooned and 66.6% of the nonballooned tubes. The final disposition of the ballooned tubes was: stomach, 2 (13.3%); duodenum, 1 (6.7%); and small bowel, 12 (80%). The final disposition of the nonballooned tubes was: stomach, 5 (33%), NS; duodenum, 9 (60%), p < .05; and small bowel, 1 (6.7%), p < .05. CONCLUSIONS Ballooned NJT have a higher rate of spontaneous transpyloric migration and are significantly more likely to achieve an optimal small bowel location.

Abstract
Allowing a patient's nutritional state to deteriorate through the perioperative period adversely affects measureable outcome related to nosocomial infection, multiple organ dysfunction, wound healing, and functional recovery. Careful preoperative nutritional assessment should include a determination of the level of stress, an evaluation of the status of the GI tract, and the development of specific plans for securing enteral access. Patients already demonstrating compromise of nutritional status (defined by > 10% weight loss and serum albumin level < 2.5 g/dL) should be considered for a minimum of 7 to 10 days of nutritional repletion prior to surgery. Widespread use of total parenteral nutrition in unselected patients is unwarranted, may actually worsen outcome, and should be reserved for preoperative nutritional support only in severely malnourished patients in whom the GI tract is unavailable. Compared with the parenteral route, use of perioperative enteral feeding has been shown to provide more consistent and beneficial results, and can be expected to promote specific advantages in long-term morbidity and mortality.

Abstract
Spontaneous transpyloric passage of nasoenteric feeding tubes is often unsuccessful in critically ill patients due to gastric ileus. The purpose of this study was to evaluate the success rate of endoscopic placement of postpyloric nasoenteric tubes and the time required to achieve goal enteral nutritional support in critically ill patients with gastric ileus. Surgical ICU patients with gastric ileus, documented by recorded high gastric residual volumes via a nasogastric tube, were identified for placement of a nasoenteric postpyloric tube via esophagogastroduodenoscopy (EGD). EGD was performed bedside in the ICU, using intravenous sedation, for placement of a 43-inch (109 cm) 8 French tungsten-weighted nasoenteric tube with an inner stylet into the duodenum, and the tube was advanced as far distally as possible. Abdominal radiograph was obtained to confirm final tube position postprocedure. Enteral feedings were initiated immediately with a full-strength formula and increased to the goal enteral feeding rate as tolerated. Thirty-four patients underwent successful placement of postpyloric nasoenteric tubes by EGD. One procedure was aborted in a patient with adult respiratory distress syndrome (ARDS) who developed hypoxemia with gastric insufflation during the EGD. The mean time to achievement of goal enteral nutritional support was 20.8 hours. Tubes remained in place for a range of 6 to 37 days. Endoscopic placement of postpyloric enteral feeding tubes is highly successful, and allows for prompt achievement of goal enteral nutritional requirements. It has two main advantages: it eliminates the risk of patient travel to radiology for fluoroscopic placement, and allows for earlier initiation of enteral feedings because spontaneous passage of weighted nasoenteric tubes into the duodenum in critically ill patients is often unsuccessful.

Abstract
BACKGROUND Obstruction of feeding tubes is a common mechanical complication associated with enteral feeding. Standard methods of flushing are not always effective. METHODS This study was conducted with patients receiving enteral feeding via nasogastric, nasoenteral, gastrostomy, or jejunostomy tubes to determine if prophylactic use of pancreatic enzymes would maintain patency of feeding tubes. Interrupted feeding regimens were used. Control patients (n = 24) received only water for flushing. After water flushing of the tube, study patients (n = 33) received a 5-mL suspension of pancreatic enzyme containing the following enzyme activity (in Federation Internationale Pharmaceutique [FIP] units): lipase, 2000; amylase, 1500; and protease, 100. The suspension also contained 90 mg of NaHCO3 to maintain a pH of 7.5. The mean duration of observation in the control and study groups was 25 and 48 days, respectively. RESULTS Compared with eight episodes (23.5%) of tube occlusions in the control group (n = 34), there was only one episode (2.6%) in the study group (n = 38). This difference was significant by the test of proportions (z = 2.68, p = .01). CONCLUSIONS In addition to routine water flushing, the routine prophylactic use of pancreatic enzyme-sodium bicarbonate suspension (pH 7.5) prevents occlusion of feeding tubes.

Abstract
Esophageal cancer often leads to total or near-total dysphagia, necessitating placement of nasogastric tubes for nutritional support. In patients with failed blind intubation or even failed fluoroscopic-guided tube placement, endoscopic guidance has a role to play. The catheter-over-guidewire technique is simple, safe, and easy to use. Over a period of 3 years, it was used in 28 patients who had esophageal cancer with absolute dysphagia. Successful placement of Levin tubes was achieved in 21 (75%) of these patients. Failure was more common in upper third lesions. The procedure was done on an outpatient basis, and no procedure-related complications were recorded in this series. To summarize, endoscopically assisted nasogastric tube placement is a useful option in esophageal cancer when blind intubation has failed, and it should be considered in preference to fluoroscopic assistance if endoscopic facilities are available.
