Abstract
BACKGROUND : Transnasal endoscopy presents a technical difficulty when inserting the flexible endoscope. It is unclear whether a particular breathing method is useful for transnasal endoscopy. Therefore, we conducted a prospective randomized controlled trial to compare endoscopic operability and patient tolerance between patients assigned to nasal breathing or oral breathing groups. METHODS : 198 eligible patients were randomly assigned to undergo transnasal endoscopy with nasal breathing or with oral breathing. Endoscopists and patients answered questionnaires on the endoscopic operability and patient tolerance using a 100-mm visual analog scale ranging from 0 (non-existent) to 100 (most difficult/unbearable). The visibility of the upper-middle pharynx was recorded. RESULTS : Patient characteristics did not differ significantly between the groups. Nasal breathing showed a higher rate of good visibility of the upper-middle pharynx than oral breathing (91.9 % vs. 27.6 %; P < 0.001). Nasal breathing showed lower mean [SD] scores than oral breathing in terms of overall technical difficulty (21.0 [11.4] vs. 35.4 [15.0]; P < 0.001). Regarding patient tolerance, nasal breathing showed lower scores than oral breathing for overall discomfort (22.1 [18.8] vs. 30.5 [20.9]; P = 0.004) and other symptoms, including nasal and throat pain, choking, suffocating, gagging, belching, and bloating (all P < 0.05). The pharyngeal bleeding rate was lower in the nasal breathing group than in the oral breathing group (0 % vs. 9.2 %; P = 0.002). CONCLUSIONS : Nasal breathing is superior to oral breathing for those performing and undergoing transnasal endoscopy. Nasal breathing led to good visibility of the upper-middle pharynx, improved endoscopic operability, and better patient tolerance, and was safer owing to decreased pharyngeal bleeding.

Abstract
Barrett’s esophagus (BE) is a condition that results from replacement of the damaged normal squamous esophageal mucosa to intestinal columnar mucosa and is the most significant predisposing factor for development of esophageal adenocarcinoma. Current guidelines recommend endoscopic evaluation for screening and surveillance based on various risk factors which has limitations such as invasiveness, availability of a trained specialist, patient logistics and cost. Trans-nasal endoscopy is a less invasive modality but still has similar limitations such as limited availability of trained specialist and costs. Non-endoscopic modalities, in comparison, require minimal intervention, can be done in an office visit and has the potential to be a more ideal choice for mass public screening and surveillance, particularly in patents at low risk for BE. These include newer generations of esophageal capsule endoscopy which provides direct visualization of BE, and tethered capsule endomicroscopy which can obtain high-resolution images of the esophagus. Various cell collection devices coupled with biomarkers have been used for BE screening. Cytosponge, in combination with TFF3, as well as EsophaCap and EsoCheck have shown promising results in various studies when used with various biomarkers. Other modalities including circulatory microRNAs and volatile organic compounds that have demonstrated favorable outcomes. Use of these cell collection methods for BE surveillance is a potential area of future research.

Abstract
BACKGROUND & AIMS Tethered capsule endomicroscopy (TCE) involves swallowing a small tethered pill that implements optical coherence tomography (OCT) imaging, procuring high resolution images of the whole esophagus. Here, we demonstrate and evaluate the feasibility and safety of TCE and a portable OCT imaging system in patients with Barrett's esophagus (BE) in a multi-center (5-site) clinical study. METHODS Untreated patients with BE as per endoscopic biopsy diagnosis were eligible to participate in the study. TCE procedures were performed in unsedated patients by either doctors or nurses. After the capsule was swallowed, the device continuously obtained 10-μm-resolution cross-sectional images as it traversed the esophagus. Following imaging, the device was withdrawn through mouth, and disinfected for subsequent reuse. BE lengths were compared to endoscopy findings when available. OCT-TCE images were compared to volumetric laser endomicroscopy (VLE) images from a patient who had undergone VLE on the same day as TCE. RESULTS 147 patients with BE were enrolled across all sites. 116 swallowed the capsule (79%), 95/114 (83.3%) men and 21/33 (63.6%) women (P = .01). High-quality OCT images were obtained in 104/111 swallowers (93.7%) who completed the procedure. The average imaging duration was 5.55 ± 1.92 minutes. The mean length of esophagus imaged per patient was 21.69 ± 5.90 cm. A blinded comparison of maximum extent of BE measured by OCT-TCE and EGD showed a strong correlation (r = 0.77-0.79). OCT-TCE images were of similar quality to those obtained by OCT-VLE. CONCLUSIONS The capabilities of TCE to be used across multiple sites, be administered to unsedated patients by either physicians or nurses who are not expert in OCT-TCE, and to rapidly and safely evaluate the microscopic structure of the esophagus make it an emerging tool for screening and surveillance of BE patients. Clinical trial registry website and trial number: NCT02994693 and NCT03459339.

Efficacy and Safety of a Novel Mouthpiece for Esophagogastroduodenoscopy: A Multi-Center, Randomized Study. Diagnostics (Basel) 2021; 11:diagnostics11030538. [PMID: 33802944 PMCID: PMC8002750 DOI: 10.3390/diagnostics11030538] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2021] [Revised: 03/04/2021] [Accepted: 03/15/2021] [Indexed: 12/24/2022] Open
Abstract
This randomized trial aimed to compare the safety and efficacy of the GAGLESS mouthpiece for esophagogastroduodenoscopy (EGD) with that of the conventional mouthpiece. In all, 90 participants were divided into the GAGLESS mouthpiece and conventional mouthpiece groups. The primary endpoint was the severity of pain using the visual analog scale (VAS), and secondary endpoints were examination time, past history of endoscopy, success of the procedure, systolic (SBP) and diastolic (DBP) blood pressure, oxygen saturation, pulse rate before and after EGD, and adverse events. Endoscopy was completed in all cases, and no complications were observed. VAS, when passing the scope through the pharynx, was 2.5 ± 2.4 and 2.0 ± 1.9 cm (p = 0.24) in the conventional and GAGLESS groups, respectively, and that, throughout the examination, was 2.5 ± 2.4 and 1.7 ± 1.5 cm (p = 0.06), respectively. The difference in blood pressure between the GAGLESS and conventional groups was not significant for SBP (p = 0.08) and significant for DBP (p = 0.03). The post-EGD difference in DBP was significantly lower in the GAGLESS group than in the conventional group. The results indicate that GAGLESS mouthpieces had a lower VAS during endoscopy than the conventional mouthpieces, and the changes in blood pressure were smaller with the GAGLESS mouthpiece.

Abstract
Purpose of review The targeted approach adopted for Barrett’s oesophagus (BO) screening is sub-optimal considering the large proportion of BO cases that are currently missed. We reviewed the literature highlighting recent technological advancements in efforts to counteract this challenge. We also provided insights into strategies that can improve the outcomes from current BO screening practises. Recent findings The standard method for BO detection, endoscopy, is invasive and expensive and therefore inappropriate for mass screening. On the other hand, endoscopy is more cost-effective for screening a high-risk population. A consensus has however not been reached on who should be screened. Risk prediction algorithms have been tested as an enrichment pre-screening tool reporting modest AUC’s but require more prospective evaluation studies. Less invasive endoscopy methods like trans-nasal endoscopy, oesophageal capsule endsocopy and non-endoscopic cell collection devices like the Cytosponge coupled with biomarker analysis have shown promise in BO detection with randomised clinical trial evidence. Summary A three-tier precision cancer programme whereby risk prediction algorithms and non-endoscopic minimally invasive cell collection devices are used to triage test a wider pool of individuals may improve the detection rate of current screening practises with minimal cost implications.

Abstract
Esophagoscopy is the standard examination standard for evaluation, diagnosis, screening and surveillance of esophageal diseases. Although it is often done, esophagoscopy costs a lot, is inconvenient, and risks complications, including cardiopulmonary complications because patients usually require routine sedation in the implementation of conventional esophagoscopic procedures. The purpose of this study is to get an overview of the results of the implementation of transnasal esophagoscopy in Department of Otorhinolaryngology Head and Neck Surgery, Division of Broncho-oesophagology, Dr. Soetomo Hospital, Surabaya, between 1 September 2012 and 30 April 2015. This study was a retrospective descriptive study with a population of all patients undergoing esophagoscopic examinations during this period. Data is taken from medical records of new patients undergoing transnasal esophagoscopy. Inclusion criteria were all patients who had been tested for transnasal esophagoscopy, and exclusion criteria were incomplete medical record data. There were 35 patients who underwent transnasal esophagoscopy examination at Department of Otorhinolaryngology Head and Neck Surgery, Division of Broncho-oesophagology, Dr. Soetomo Hospital, Surabayaduring the study period. The mean of patients who participated in the study was 54.17 ± 14.02. 23 male patients (63.89%), while 12 female patients or 34.11%. Indications of dysfagi are found in all age groups, most in the age group 51-70 years. Metastases in head and neck malignancies are found in the age group 31 - 50 years and 51 - 70 years. Indications for heartburn are found in the age group 21-50 years and 51-70 years. In conclusion, the results of transnasal esophagoscopic examination showed that most patients had a normal picture (60%) and a positive picture with an esophageal abnormality of 40%. The most common features are lesions in the mucosal esophagus lumen, scar, masses and stenosis.

Abstract
BACKGROUND AND AIM Discomfort associated with the gag reflex during transoral endoscopy can be troublesome. To overcome this problem during esophagogastroduodenoscopy (EGD), we recently developed a novel mouthpiece. The aim of the present study was to compare acceptance and tolerability of transoral EGD with conventional and new mouthpieces in unsedated patients and analyze the effects of the new mouthpiece. METHODS This study consisted of two phases of cephalometric and EGD examinations to analyze the effects of the new mouthpiece. Cephalometry was carried out in six subjects to evaluate differences in the size of the pharynx (anteroposterior diameter of the oropharynx and longitudinal diameter of the oral cavity) when subjects held the conventional mouthpiece (MAJ674) or the new mouthpiece in their mouths. EGD was done in 10 subjects using the conventional or new mouthpiece to evaluate the number of times the gag reflex occurred, examinee discomfort, and endoscope operability during EGD using a visual analogue scale (VAS). RESULTS Anteroposterior diameter of the oropharynx and longitudinal diameter of the oral cavity were significantly larger with the new mouthpiece than with the conventional mouthpiece (oropharynx: P = 0.03; oral cavity: P = 0.03). With the new mouthpiece during EGD, subjects had significantly fewer instances of the gag reflex (P = 0.01); VAS score for discomfort was significantly lower (P < 0.01) and score for endoscope operability was significantly higher (P = 0.04). CONCLUSION The new mouthpiece we developed reduced the gag reflex during EGD by extending the pharynx, thus decreasing examinee discomfort and increasing endoscopic operability.

In-office laryngology procedures (IOLP) are increasingly seen as standard-of-care, and while generally considered safe, high-quality evidence supporting the latter statement is lacking. This review aims to summarize recent literature regarding the safety of IOLP. RECENT FINDINGS There is a paucity of guidelines and standardized protocols for IOLP. To date, there is one available safety protocol specific to in-office laser procedures. Haemodynamic changes during IOLP have been documented and the significance of these changes continues to be unclear. Therefore, monitoring of vital signs is recommended. Continuing antithrombotic therapy during IOLP also appears safe, and this decision may be left to surgeon discretion. A protocol for management of antithrombotic therapy prior to in-office laser procedures is available. Actual serum lidocaine levels following topical application of mixed lidocaine preparations falls well below reported toxic levels but persists for longer than previously reported. SUMMARY IOLP are safer that suspension laryngoscopy under general anaesthetic. Although complication rates of IOLP are low, patient characteristics and potential complications of both the procedure and of topical anaesthetic use must be considered. One must be prepared and equipped to deal with these potential complications.

Abstract
Background and study aims The repair costs of gastrointestinal endoscopes account for a significant proportion of the total budget of an endoscopy unit. This study evaluated the repair costs of small-caliber endoscopes and conventional endoscopes used in esophagogastroduodenoscopy (EGD). Patients and methods A retrospective analysis of upper gastrointestinal endoscope damage and repair costs between April 2012 and May 2019 was performed at the Toyoshima Endoscopy Clinic. Conventional endoscopes (GIF-H260, GIF-HQ290, and GIF-H290Z) were used for transoral EGD while small-caliber endoscopes (GIF-XP260N and GIF-XP290N) were used for transnasal or transoral EGD. Results Three small-caliber endoscopes and five conventional endoscopes were used for 1,031 procedures and 31,192 procedures, respectively. The number of procedures/damage incidence for small-caliber endoscope and conventional endoscopes was 344 and 1950, respectively. Damage incidence for small-caliber endoscopes was significantly higher than for conventional endoscopes ( P = 0.014). Repair costs/procedure were $ 5.95 ± $132 for small-caliber endoscopes and $2.41 ± $115 for conventional endoscopes. Repair costs/procedure for small-caliber endoscopes were more than twice those for conventional endoscopes. Conclusions Small-caliber endoscopes are more fragile than conventional endoscopes.

Abstract
Introduction Numerous indications require regular upper gastrointestinal endoscopy (oesophagogastroduodenoscopy; EGD) in outpatients. In most cases, peroral gastroscopy is performed. The aim of this study was to evaluate the need of transnasal gastroscopy (nEGD) in outpatients. Methods A questionnaire was used to assess patients’ preferred choice of method, previous experience with EGD, psychological aspects and sociodemographic data. Furthermore, patient satisfaction with and potentially perceived discomfort during the examination as well as preference for a method in regard to future examinations was evaluated. Results From September 2016 to March 2017, a total of 283 outpatients at endoscopy of the University Hospital of Leipzig were approached to participate in the study. 196 patients were eligible, of whom 116 (60%) chose nEGD. For 87 patients (87/283, 31%) nEGD had to be excluded for medical reasons. The average age in the total sample was 53 (±17) years. 147 (77%) have had previous experience with peroral EGD (oEGD). Of the nEGD examined patients 83% were fairly up to extremely satisfied with the procedure. Satisfaction significantly predicted the choice of future EGD examinations. Nasal pain experienced during nEGDs was associated with rejection of nEGD in further EGD examinations (p<0.01). Patients who did choose a specific procedure were more likely to select the same procedure as their future preference (χ²= 73.6, df=1, p<0.001); this preference was unaffected by the procedure that had been chosen previously (reselecting nEGD: 84%, oEGD: 89%, p=0.874). Conclusion nEGD without sedation is a viable alternative. Patient satisfaction with nEGD is high, and reselection rate for nEGD is similar to that for oEGD. As a result of this study nEGD is now offered as a routine procedure at the University of Leipzig. Trial registration number NCT03663491.

Abstract
BACKGROUND AND STUDY AIMS Unsedated transnasal endoscopy (uTNE) has become accepted as a safe and tolerable method for upper gastrointestinal tact examinations. Epistaxis is 1 of the major complications of TNE, though its risk factors have not been elucidated. Generally, patients administered an anticoagulant or antiplatelet drug are considered to have an increased risk of epistaxis during TNE. Here, we investigated risk factors of epistaxis in patients undergoing uTNE, with focus on those who received antithrombotic agents. PATIENTS AND METHODS We enrolled 6860 patients (average age 55.6 ± 12.97 years; 3405 males, 3455 females) who underwent uTNE and received the same preparations for the procedure. Epistaxis was evaluated using endoscopic images obtained while withdrawing the scope through the nostril. We also noted current use of medications including anticoagulant or antiplatelet agents prior to the endoscopic examination. RESULTS Epistaxis occurred in 3.6 % of the enrolled patients (245/6860), and that rate was significantly higher in younger patients (average age 49.31 ± 11.8 years for epistaxis group vs. 55.83 ± 13.0 years for no epistaxis group, P < 0.01) as well as females (4.78 % vs. 2.35 %, P < 0.01). The odds ratio for occurrence of epistaxis was 2.31 (95 %CI: 1.746 - 3.167) in the younger patients and 2.02 (95 % CI: 1.542 - 2.659) in females. In contrast, there was no significant difference for rate of epistaxis between patients with and without treatment with an antithrombotic agent (3.0 % vs. 3.6 %). CONCLUSIONS The rate of epistaxis was higher in younger and female patients. Importantly, that rate was not significantly increased in patients who were administered an antithrombotic agent.

Abstract
BACKGROUND AND AIM Sniff test is a common method before unsedated transnasal esophago-gastro-duodenoscopy (UT-EGD) to select a nostril insertion site. Yet there is no objective method to select a more specific meatus insertion tract for anesthesia and insertion. We devised an endoscopic meatus scoring scale by anterior meatuscopy to select the most optimal meatus insertion tract. We hypothesized that meatuscopy instead of sniff test might improve tolerance and reduce adverse events during nasal anesthesia and UT-EGD. METHODS A prospective randomized controlled trial to compare patient tolerance and adverse events. RESULTS A total of 359 patients were assessed and finally 310 patients were analyzed. There were no statistical differences in patient characteristics and insertion failure rates. Pain scores during nasal anesthesia, nasal insertion/exsertion, UT-EGD, and overall tolerance were significantly lower in the meatuscopy group than sniff test group. Compared with the sniff tested patients, the meatuscopied patients had significantly lower epistaxis rates during insertion/exsertion, better visual capacity after decongestive anesthesia, and shorter total procedure time. A significantly higher proportion of the meatuscopied than sniff tested patients would like to receive the same procedure next time. Nasal discharge, nasal pain, epistaxis, and blowing out blood clots occurred significantly less frequent in the meatuscopy group than sniff test group. More sniff tested than meatuscopied patients had headache, delayed epistaxis, and sinusitis although they were not statistically significant. CONCLUSION Selection of an optimal meatus insertion tract by an anterior meatuscopy causes lesser nasal pain, epistaxis, and post-procedural side effects in nasal anesthesia and UT-EGD than the conventional sniff test.

Hemodynamic Parameters during Laryngoscopic Procedures in the Office and in the Operating Room. Otolaryngol Head Neck Surg 2016; 155:466-72.

Abstract
Objective Previous research has shown that office-based laryngoscopic procedures can induce hemodynamic changes, including tachycardia and severe hypertension, calling into question the safety of these procedures. However, comparison between office and operating room (OR) procedures has not been carried out. Therefore, we prospectively measured hemodynamic variables in both settings to compare hemodynamic changes between office and OR procedures. Study Design Prospective cohort study. Setting Single academic center. Subjects and Methods Subjects undergoing office and OR laryngoscopic procedures were prospectively identified, and 92 OR and 70 office subjects were included. Heart rate and blood pressure were measured at established time points before, during, and after the procedures. Descriptive and comparative statistical analyses were conducted. Results Severe hemodynamic events, either tachycardia or severe hypertension (blood pressure >180 mm Hg systolic or >110 mm Hg diastolic), occurred significantly more frequently in OR than office procedures (41% vs 20%; P = .006). OR severe hemodynamic events occurred more commonly than previously reported rates in the office (41% vs 28%; P = .012). Regression analyses showed that the odds of having a severe hemodynamic event were 3.66 times higher in OR versus office procedures. Conclusion Severe hemodynamic events are more likely to occur in the OR than in the office during laryngologic procedures. While larger studies will be required to establish rates of dangerous cardiovascular events in laryngoscopic procedures, hemodynamic parameters indicate that office-based procedures have a safety benefit for procedures that can be conducted in either setting.

Abstract
BACKGROUND AND AIMS Unsedated transnasal endoscopy (TNE) is safer and less costly than sedated EGD. The aim of this study was to evaluate the performance of TNE with biopsies in monitoring the esophageal mucosa of pediatric patients with eosinophilic esophagitis. METHODS Patients between 8 and 17 years of age with eosinophilic esophagitis and their parents were enrolled. Unsedated TNE was performed. A 2.8-mm (1.2-mm channel) or a 4-mm flexible bronchoscope (2-mm channel) was used, and esophageal biopsy specimens were obtained. Biopsy specimen analysis, duration, adverse events, and billing charges of TNE were assessed. Immediately after TNE and a minimum of 2 weeks later, a modified Group Health Association of America 9 survey and a preference questionnaire were completed, respectively. RESULTS Twenty-one of 22 enrolled patients underwent TNE. TNE was performed with no serious adverse events. Histopathological analysis revealed 0 eosinophils per high-power field (n = 12), fewer than 15 eosinophils per high-power field (n = 4), and more than 15 eosinophils per high-power field (n = 5). The total epithelial surface area of mucosal biopsy samples from either TNE Forceps (1.2 mm or 2 mm biopsy channel forceps) compared with those obtained during the subject's previous EGD by using standard endoscopic forceps was not statistically different (P = .308 [1.2 mm]/P = .492 [2 mm]). All parents and 76.2% of subjects would undergo the TNE again. TNE was preferred over EGD by 85.7% of parents and 52.4% of subjects. The modified Group Health Association of America 9 survey revealed a high degree of satisfaction (average, 43.19 ± 2.6; maximum score, 45). Charges associated with TNE were 60.1% lower than for previous EGDs. CONCLUSIONS Unsedated TNE is an effective, lower-cost procedure for monitoring the esophageal mucosa of children with eosinophilic esophagitis.

Abstract
BACKGROUND AND STUDY AIMS Ultra-thin caliber endoscopes (UTCEs) are versatile and applicable in various conditions. However, only limited data exist on the actual daily clinical use of UTCEs. The aim of our study was to determine indications for UTCEs in a large patient cohort. In turn, our 2 main objectives were (1) to evaluate patient comfort and safety and (2) to determine benefits and potential advantages associated with the use of UTCEs in this same cohort. PATIENTS AND METHODS We performed a retrospective analysis of our prospective database of 1028 procedures with UTCEs in 457 patients. All procedures were carried out in the Department of Gastroenterology and Hepatology, VU University Medical Center, in Amsterdam, the Netherlands, between May 2008 and May 2014. In these procedures, either the Fujinon (Tokyo, Japan) EG-530N UTCE or the Olympus (Tokyo, Japan) GIF N-180 UTCE was used. RESULTS Mean (standard deviation [SD]) age of patients was 64 (20) years, and most (60 %) of the patients were men. Most (61 %) of the underlying diseases, requiring endoscopic procedures, were found in the esophagus. Of the procedures performed, 91 % were successful, and 82 % were therapeutic. In comparison with regular endoscopes, the most important advantage of the UTCE was the ability to pass a stenosis (37 %), followed by nasogastric feeding tube placement (13 %). Newer and more innovative uses of the UTCE were percutaneous endoscopic gastrostomy (PEG)-jejunal extension placement with endoscope introduction through existing PEG tract, retrograde esophageal introduction through existing PEG tract, inspection of colonic neovagina stenosis, and direct inspection of the common bile duct. CONCLUSIONS In everyday clinical practice, the UTCE has specific advantages over conventional endoscopes because of its small caliber. The 3 main advantages are (1) introduction of high-grade strictures; (2) introduction of fistulas, including PEG fistula; and (3) increased patient comfort. The endoscopist should appreciate these advantages and consider use of the UTCE accordingly.

Abstract
Objectives: A preponderance of literature supports the safety of office-based flexible endoscopic procedures of the upper aerodigestive tract; however, until recently there were no data regarding hemodynamic stability during these procedures. A recent study showed intraprocedure changes in patients' hemodynamic parameters, raising the concern that perhaps patients should be monitored during these procedures. The aim of our study was to determine whether physiologically significant alterations in vital signs occur during office-based flexible endoscopic procedures. Methods: We performed a retrospective review of 100 consecutive patients who underwent office-based flexible endoscopic procedures of the upper aerodigestive tract from July 2010 to October 2011. Baseline values and the maximal changes in systolic blood pressure, diastolic blood pressure, heart rate, and oxygen saturation were recorded and compared. Results: One hundred consecutive patients were included in the study. Twenty-one patients (21%) had severe hypertension and 40 patients (40%) had tachycardia during the procedure. The mean change overall in systolic blood pressure was 26.2 mm Hg (p < 0.001), the mean change in diastolic blood pressure was 13.9 mm Hg (p < 0.001), the mean change in heart rate was 16.6 beats per minute (p < 0.001), and the mean change in oxygen saturation was 1.6% (p < 0.001). These changes were significant. On further breakdown into groups, patients over 50 years of age and patients who were undergoing esophageal or laser procedures had significant elevations in heart rate (p = 0.01 and p = 0.04, respectively). An elevation in diastolic blood pressure was also significant in patients who were undergoing esophageal or laser procedures (p = 0.04 for both). Conclusions: These data concur with those of the previous report that found potentially significant hemodynamic changes during office-based procedures. Although preliminary, our findings suggest that it may be wise to monitor vital signs in patients over 50 years of age and patients who are undergoing an esophageal or laser procedure who are at risk for complications that could arise from tachycardia and hypertension.

Abstract
BACKGROUND/PURPOSE Differences in patient tolerance, acceptance, and satisfaction of esophagogastroduodenoscopy (EGD) between transnasal (TN) and peroral (PO) routes using a 5-mm video endoscope. METHODS A total of 220 enrolled patients were assigned randomly to two groups undergoing EGD-110 patients each for TN and PO. The successful rate, procedure time, and adverse events were recorded. After the procedure, patients answered a validated questionnaire of tolerance, acceptance, and satisfaction. RESULTS There were 6 failures (5.7%) of nasal intubation and two nasal bleeding (2%) among 105 TN-EGD procedures. All PO patients (n=102) completed EGD successfully without adverse event. Compared to PO, the procedure of TN achieved lower successful rate (94% vs. 100%, p=0.01), was complicated with epistaxis (2% vs. 0%) and took longer (mean ± SD 19.9 ± 6.1 min vs. 16.8 ± 6.4 min, p=0.0001). The patients undergoing TN-EGD indicated less discomfort during passing pharynx (scores of 2.1 ± 2.0 vs. 3.1 ± 2.6, p=0.011) but more pain during inserting scope (scores of 2.2 ± 1.6 vs. 1.5 ± 1.8, p=0.0001). Eventually, there were no significant differences between TN and PO regarding the overall procedure discomfort (scores of 10.7 ± 6.6 vs. 11.1 ± 7.8 scores, p=0.9), satisfaction (scores of 41.2 ± 4.2 vs. 41.3 ± 4.6, p=0.91), and acceptability (87.8% vs. 94.2%, p=0.91). CONCLUSION PO intubation seems an excellent alternative method when using a 5-mm ultrathin endoscopy because it achieves comparable patient tolerance, acceptance, and satisfaction as TN intubation, takes less time and causes lower intubation failure and epistaxis.

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
BACKGROUND AND AIM The assessment and treatment of advanced gastrointestinal (GI) strictures, which are defined as the inability to pass through the strictured segment with standard endoscopes, might require radiological work-up, repeated endoscopies and surgery. The aim of the present study was to assess the role of ultrathin endoscopy (UTE) for the evaluation and treatment of advanced GI strictures. METHODS Patients in whom an initial diagnostic upper or lower endoscopy attempt was incomplete because of a tight stricture underwent a second procedure with a UTE (5.9 mm diameter) in the same session. An interventional endoscopic therapy was also carried out according to the etiology and nature of the stricture using the same UTE. Diagnostic and therapeutic outcomes were recorded and followed up prospectively. The study was conducted in a tertiary endoscopy center. RESULTS During a one and half year study period, 62 patients (51 at upper and 11 at lower endoscopy) were detected with advanced GI stricture among 8456 diagnostic upper and 3815 lower endoscopy patients. A complete endoscopic examination was successful with UTE in 40 (78%) patients with upper and in nine patients (82%) with lower GI strictures. An interventional procedure was also carried out in 16 patients with the assistance of UTE. CONCLUSION UTE is a useful tool for the evaluation of patients with advanced GI strictures. It provides a complete diagnostic endoscopy in most patients and gives an opportunity for therapeutic endoscopic procedures.

Abstract
BACKGROUND Endoscopic screening for esophageal neoplasia can identify patients eligible for early intervention for precancerous lesions. Unsedated transnasal esophagoscopy may provide an efficient and accurate endoscopic assessment with fewer risks and less cost, compared with conventional upper endoscopy. OBJECTIVE To assess the feasibility, safety, acceptability, and yield of unsedated transnasal esophagoscopy in a primary care population. DESIGN Multicenter, prospective, cross-sectional study. SETTING Two outpatient tertiary-care centers. PATIENTS This study involved a general medical clinic population aged between 40 and 85 years. INTERVENTION Unsedated, office-based transnasal esophagoscopy. MAIN OUTCOME MEASUREMENTS Procedure yield; completeness of examination; procedure length; adverse events and complications; choking, gagging, pain, or anxiety during the examination; and overall tolerability. RESULTS A total of 426 participants (mean [± standard deviation] age 55.8 ± 9.5 years; 43% male) enrolled in the study, and 422 (99%) completed the examination. Mean (± standard deviation) examination time was 3.7 ± 1.8 minutes. There were no serious adverse events, and 12 participants (2.8%) reported minor complications. Participants reported minimal choking, gagging, pain, or anxiety. The examination was well-tolerated by most participants. Overall, 38% of participants had an esophageal finding that changed management (34% erosive esophagitis, 4% Barrett's esophagus). LIMITATIONS Nonrandomized study, tertiary-care centers only, self-selected population with a large proportion reporting esophageal symptoms. CONCLUSION Unsedated transnasal esophagoscopy is a feasible, safe, and well-tolerated method to screen for esophageal disease in a primary care population. Endoscopic findings are common in this patient population.

Abstract
BACKGROUND Transnasal esophagogastroduodenoscopy (EGD) with small-caliber endoscopy appears to be less stressful to the cardiovascular system and has good patient tolerance. ENDO LEADER, a newly developed mouthpiece for peroral EGD with small-caliber endoscopy, is expected to reduce patient stress. We compared the patient acceptance, cardiovascular tolerance and autonomic nervous responses between transnasal EGD and peroral EGD with ENDO LEADER. PATIENTS AND METHODS A total of 130 patients (transnasal group, 77; peroral group, 53) were enrolled. Pulse rate (P), blood pressure (BP), and peripheral blood oxygen saturation (SpO(2) ) were monitored. Acceptance of EGD was also assessed. Autonomic nervous responses were evaluated through analysis of heart rate variability using amplitude of the high-frequency component (HF) and low-frequency-to-high-frequency power ratio (LF/HF) as indices of cardiac vagal activity and sympathetic activity, respectively. RESULTS Analysis of patient acceptance showed no differences between the two groups, except with regard to nasal pain. Increases in BP and P between before and during EGD examination were significantly higher in the peroral group. Although throat pain and overall tolerance scores were significantly correlated with ΔBP and ΔP, no correlations with nasal pain score were noted. Heart rate variability analysis revealed that heart rate increased significantly in the peroral group, but there were no differences in ΔHF or ΔLF/HF between the two groups. CONCLUSIONS Patient acceptance was not significantly different between the transnasal and peroral with ENDO LEADER groups; however, transnasal EGD appears to be less stressful to the sympathetic nervous system, leading to smaller elevations in BP, P and heart rate.

Abstract
BACKGROUND The optimal topical anesthesia regimen for unsedated transnasal endoscopy is unknown. The addition of a nasal decongestant, such as xylometazoline (X), to a topical anesthestic may improve patient comfort. OBJECTIVE To determine the effectiveness of lidocaine (L) versus L plus X (LX) for anesthesia in unsedated transnasal endoscopy. METHODS Consecutive participants of the Aklavik Helicobacter pylori project were prospectively randomly assigned to receive LX or L for unsedated transnasal 4.9 mm ultrathin endoscopy. The primary outcome was overall procedure discomfort on a validated 10-point visual analogue scale (1 = no discomfort, 10 = severe discomfort). Secondary outcomes included pain, endoscope insertion difficulty, gagging, adverse events and encounter times. Results were presented as mean +/- SD, difference in mean, 95% CI. RESULTS A total of 181 patients were randomly assigned to receive LX (n=94) and L (n=87). Baseline characteristics between the two groups were similar (mean age 40 years, 59% women). Overall, patient procedural discomfort with LX and L were 4.2+/-2.4 versus 3.9+/-2.1, respectively (0.29; 95% CI -0.39 to 0.96). Transnasal insertion difficulty was significantly lower with LX than with L (2.4+/-2.1 versus 3.2+/-2.8, respectively [-0.80; 95% CI -1.54 to -0.06]). Compared with L, the use of LX was associated with significantly less time needed to apply anesthesia (2.4+/-1.8 min versus 3.5+/-2.2 min, respectively [-1.10; 95% CI -1.71 min to -0.50 min]) and less time for insertion (3.2+/-1.8 min versus 3.9+/-2.2 min, respectively [-0.70 min; 95% CI -1.30 min to -0.10 min]). Epistaxis was rare but occurred less frequently with LX (1.1%) than with L (4.6%) (P=0.19). CONCLUSIONS LX did not improve patient comfort for transnasal endoscopy compared with L alone. However, LX was associated with less difficulty with endoscope transnasal insertion and reduced insertion time. Further studies on the optimal regimen and dosing of anesthesia are required.

Abstract
BACKGROUND Unsedated transnasal gastroscopy is a technique with unverified clinical advantages. OBJECTIVE To evaluate the efficacy and procedure times with transnasal gastroscopy by physicians with no previous experience in transnasal endoscopy. METHODS Unsedated transnasal gastroscopy using 4.9 mm ultrathin transnasal gastroscopes with randomization to two different biopsy forceps was prospectively evaluated during a single day in January 2008. The outcomes included patient tolerance (scale: 1, no discomfort; 10, severe discomfort), physician technical assessment (1, excellent; 10, very poor), gastric biopsy quality, adverse events and procedure times. RESULTS Twenty patients underwent transnasal gastroscopy. Nineteen patients (95%) successfully completed transnasal gastroscopy. The patient-reported mean (+/- SD) overall discomfort level during the procedure was 4.0+/-1.9 compared with a physician-estimated level of 3.2+/-1.7 (P=0.04). Only 10% (n=2) reported they would have preferred sedated over unsedated gastroscopy. Mean total encounter time from anesthesia to discharge was 33.5+/-9.3 min. The time from anesthesia to insertion was 7.0+/-5.3 min and from room exit to discharge 6.2+/-2.9 min. No patients who had gastric biopsies taken (zero of 14) had any of unacceptable quality. The only adverse event was distressing sensations (dyspnea, dizziness) in one patient that started during pre-endoscopy anesthetic application, persisting postendoscopy, but without any abnormalities in vital signs. CONCLUSION Assuming the adverse event was a rare reaction, early experience with unsedated ultrathin transnasal gastroscopy was an efficient, effective and well-tolerated procedure for evaluation of the upper gastrointestinal tract.

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.
