JGH Open 2022; 6:864-868. [PMID: 36514497 PMCID: PMC9730706 DOI: 10.1002/jgh3.12834] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2022] [Revised: 10/10/2022] [Accepted: 10/15/2022] [Indexed: 11/09/2022]
Abstract
Background and Aim Discrepancies have been reported in the circumferential locations of mild mucosal breaks. We investigated their locations using a new method. Methods This is a retrospective study. Eighty patients (Grade A/B: 53/27) with mild mucosal breaks in the lower esophagus were examined. Since the 3 o'clock position corresponded to the right wall of the lower esophagus using our method with sufficient accuracy, the circumferential locations of mucosal breaks were identified as times on a clock face, which were changed to circular data to calculate the mean direction. The circumferential distribution of mucosal breaks was evaluated in the single lesion group (single group) and multiple lesion group (multiple group). Results Forty-eight of 80 patients had 1 mucosal break, while 32 had ≥2 mucosal breaks. Circumferential locations markedly differed between the single and multiple groups. In the single group, mucosal breaks were exclusively distributed between 2 and 7 o'clock, with 50% in the 3 o'clock direction (right wall). In the multiple group, 81 mucosal breaks were distributed circumferentially, not uniformly; however, at least 1 lesion was located between 2 and 7 o'clock in 91% of subjects. Therefore, a factor for the development of mucosal breaks from the right to posterior wall was present in both groups. Conclusion In the single group, mucosal breaks were localized from the right to posterior wall, mainly in the right wall. In the multiple group, mucosal breaks were located circumferentially, but often between the right lateral and posterior wall. These two distributions significantly differed.Clinical trial registration: This is a retrospective study, so it was not registered.

Abstract
This study aimed to examine the range of beige colored mucosa (BCM) in patients with esophageal eosinophilic infiltration (EEI) using narrow-band imaging (NBI). In this retrospective study, EEI was confirmed histologically in 12 consecutive patients from January 2014 to December 2017. The BCM tone on NBI without magnifying endoscopy was evaluated, and red, green, and blue (RGB) values of BCM and normal mucosa were measured. BCM was macroscopically classified into 2 groups (bright and dark) using cluster analysis. Histopathological analysis was performed in 1 patient who underwent biopsy for both normal mucosa and BCM. All 12 patients presented with BCM. Endoscopy revealed fixed rings, longitudinal furrows, mucosal edema, and exudate in 3, 12, 10, and 8 patients, respectively. Strictures were absent. Five patients had findings suggestive of gastroesophageal reflux disease. In the cluster analysis, 5 and 7 patients had bright and dark BCM, respectively. Consistent results were noted when we categorized patients according to their macroscopic characteristics. RGB values of the BCM and normal mucosa were measured-normal mucosa: R: 99.8 ± 16.5, G: 121.7 ± 23.1, and B: 93.4 ± 19.2; BCM: R: 152.0 ± 31.3, G: 123.9 ± 35.0, and B: 97.5 ± 29.5. BCM had significantly higher R values than normal mucosa (P = .0001). All parameters were significantly lower in the dark BCM group than in the bright BCM group (P < .001). Histopathological analysis revealed expansion of the epithelial intercellular space, eosinophilic infiltration, and basal cell hyperplasia at the BCM sites. BCM was observed in all cases of EEI. RGB values differed between bright and dark BCM. Assessing BCM tone using NBI is a potentially novel diagnostic method for EEI.

Abstract
Barrett's esophagus (BE) is an endoscopically identifiable premalignant condition for esophageal adenocarcinoma (EAC). To diagnose BE precisely, careful inspection of the anatomic landmarks, including the esophagogastric junction and the squamocolumnar junction is important. The distal end of the palisade vessels and the proximal end of the gastric folds are used as the landmark of the esophagogastric junction in endoscopic diagnosis, with the latter solely used internationally, except in some Asian countries, including Japan. In addition, the diagnostic criteria adopted internationally for BE are inconsistent, particularly between Japan and Western countries. Recently updated guidelines in Western countries have included length criteria, with a 1‐cm threshold of columnar epithelium by endoscopic observation and/or histologic confirmation of the presence of specialized intestinal metaplasia. Since BE is endoscopically diagnosed at any length without histologic assessment in Japan, the reported prevalence of short‐segment BE is very high in Japan compared with that in Western countries. Although guidelines on screening exist for BE, the current strategies based on the presence of chronic gastroesophageal reflux disease with multiple risk factors may miss the opportunity for early detection of EAC. Indeed, up to 40% of patients with EAC have no history of chronic gastroesophageal reflux disease. To discuss BE on the same footing worldwide, standardization of diagnostic criteria, screening indication, and establishment of effective techniques for detecting dysplastic lesions are eagerly awaited. Japanese guidelines for BE should be revised regarding the length criteria, including the minimum length and long‐segment BE, in line with the recently updated Western guidelines.

Abstract
Background/Aims The gastric acid pocket has an important role in gastroesophageal reflux disease development. In this study, we utilized a novel 8-channel pH monitoring system with sensor intervals of 1 cm on the vertical axis for evaluation of postprandial gastric acid pocket in healthy Japanese adults, as well as the effects of vonoprazan and rabeprazole. Methods Twelve healthy volunteers without Helicobacter pylori infection were enrolled. A catheter was inserted transnasally and positioned under X-ray guidance, then postprandial acid pocket formation was monitored over time in a sitting position. Thereafter, acid pocket changes were assessed following administration of vonoprazan (20 mg) or rabeprazole (20 mg). Results The gastric acid pocket was successfully measured by use of the present system in 10 cases, while failure occurred in 2 because of inappropriate catheter positioning. Observed acid pockets were visualized with a mean length of 2.2 ± 0.4 channels on the top layer of food contents approximately 20 minutes after finishing a meal. There were some variations for lasting time of the acid pocket. Complete elimination within 3 hours after administration of vonoprazan was noted in all cases. Likewise, following administration of rabeprazole, the acid pocket was eliminated in 7 cases, while acidity was reduced though the pocket remained observable in 3. Conclusions Gastric acid pocket observations were possible using our novel vertical 8-channel sensor catheter. The present findings showed that vonoprazan strongly suppressed acid secretion within a short period, suggesting its effectiveness for gastroesophageal reflux disease treatment.

Abstract
Objective Esophageal mucosal breaks are considered to occur circumferentially in locations with high exposure to acid. In the present study, we investigated the circumferential localization of esophageal mucosal breaks based on their distance from the esophagogastric junction. Methods The vertical and circumferential localization of 625 esophageal longitudinal mucosal breaks was examined in 398 patients with mild reflux esophagitis. Results The number of mucosal breaks in which the distal end was located 0-1 cm from the esophagogastric junction was 454, while those in which the distal end was located 1-2, 2-3, and >3 cm from the junction were 125, 28, and 18, respectively. There was a marked difference in the circumferential distribution among the groups defined by distance from that junction. Esophageal mucosal breaks whose distal end were located 0-1 cm from the esophagogastric junction were mainly found on the right anterior wall of the esophagus, while those located 1-2 cm from the junction were mainly found on the right wall, and those located 2-3 and >3 cm from the junction were mainly found on the posterior wall. Conclusion Esophageal mucosal breaks occurring relatively near the esophagogastric junction mainly exist on the right anterior wall, whereas those farther from that junction tend to exist on the posterior wall of the esophagus. The circumferential location of esophageal mucosa highly exposed to refluxed gastric contents changes based on the distance from the esophagogastric junction.

Abstract
BACKGROUND Esophageal adenocarcinoma (EAC) is frequently found on the right-anterior wall of the distal esophagus in short-segment Barrett's esophagus (SSBE) patients. However, the endoscopic characteristics of EAC in cases with long-segment BE (LSBE) and squamous cell carcinoma (ESCC) in the lower esophagus remain to be fully evaluated. Here, we determined the circumferential distribution and clinical characteristics of esophageal cancer occurring in the lower esophagus based on histological subtype. METHODS We retrospectively reviewed the medical records of 150 patients with esophageal cancer (ESCC, n = 100; EAC, n = 50) diagnosed at our hospital or a related facility between January 2002 and June 2017, including information regarding endoscopic findings, etiology, and clinical parameters. RESULTS Of the 100 patients with ESCC, 28 lesions were located in the lower esophagus, though characteristic circumferential distribution was not seen regardless of location. Those showed a greater frequency of smoking and drinking habit and gastric mucosal atrophy as compared to patients with EAC. Consistent with the previous reports, EAC in SSBE (n = 41) was frequently located on the right-anterior wall. Likewise, EAC at the esophagogastric junction (EGJ) in LSBE was frequently located on the right-anterior wall, while EAC distant from the EGJ showed no characteristic circumferential distribution. CONCLUSION Our results showed no circumferential predilection for ESCC in the lower esophagus, suggesting that development of this type of lesion may be less affected by gastroesophageal reflux. In addition, EAC at the EGJ was frequently found on the right-anterior wall irrespective of BE length.

Abstract
Background and study aims Esophageal mucosal breaks in patients with reflux esophagitis (RE) have a unique circumferential distribution. However, the specific location of mucosal breaks during recurrence of RE remains unclear. We investigated the circumferential distribution of mucosal breaks in patients with recurrent RE and compared their location to that noted at the initial diagnosis. Patients and methods We retrospectively enrolled patients with recurrent RE with Los Angeles (LA) grade A-C who were treated at our University Hospital between July 1996 and June 2014. The circumferential distribution of esophageal mucosal breaks was evaluated at the time of the initial diagnosis and again at the time of recurrence. Information regarding clinical parameters, including proton pump inhibitor administration, presence of hiatal hernia, and mucosal atrophy, was also reviewed. Results A total of 114 patients with recurrent RE were examined during the study period, with a mean duration to recurrence after initial diagnosis of 39.4 months. The majority (72.8 %) had the same LA grade at recurrence. In addition, recurrent mucosal breaks in 96 (84.2 %) patients were observed to have occurred in the same circumferential location as at the initial diagnosis, while those in 18 (15.8 %) were observed in a different location. When recurrent lesions had a different location, the LA grade also tended to be different (P = 0.02). Conclusions We found that most patients with recurrent RE developed lesions in the same circumferential location as noted for the initial lesions. Those in different locations at recurrence were associated with a change in LA grade.

Abstract
BACKGROUND AND AIM Linear furrows are the most frequently found endoscopic abnormality in patients with esophageal eosinophilia (EE); however, the precise endoscopic features remain to be fully elucidated. Here, we aimed to clarify the endoscopic features of EE, essential for the diagnosis of eosinophilic esophagitis (EoE), by focusing on the specific locations of linear furrows in a Japanese population. METHODS We enrolled 70 cases with EE (≥15 eosinophils/high-power field) who were diagnosed at our hospital and related facilities. Information regarding endoscopic findings and clinical parameters was retrospectively reviewed. Next, the position of linear furrows in relation to esophageal longitudinal folds (ridge or valley) was evaluated in each case and compared with the position of mucosal breaks in patients with reflux esophagitis. Finally, the relationship between linear furrows and eosinophilic infiltration was evaluated. RESULTS Of the 70 EE patients, 63 (90%) had linear furrows. Those occurred in a radial pattern and were widespread throughout the lower to upper esophagus, and exclusively found in esophageal longitudinal mucosal fold valleys, not on ridges, which was different from the position of mucosal breaks in patients with reflux esophagitis. Increased eosinophilic infiltration was significantly more frequent in linear furrows in the valleys (93%) as compared to mucosa on adjacent ridges (60%) (P < 0.05). CONCLUSION Investigation of these endoscopic characteristics, especially by focusing on linear furrows in esophageal mucosal fold valleys, may provide important clues for more accurate diagnosis of EoE.

Abstract
Objective To clarify the relationship between the shape and circumferential location of non-circumferential short-segment Barrett's esophagus (SSBE). Methods We examined 3,788 subjects (2,497 males, 1,291 females; mean age 52.4 years) who underwent upper GI endoscopy as part of a detailed medical checkup. The presence of columnar-appearing mucosa ≥10 mm long in the distal esophagus was diagnosed as BE and then divided into circumferential and non-circumferential localized types. Localized SSBE was further divided into round and sharp types based on the shape of the proximal margin. Results SSBE was endoscopically observed in 197 subjects (5.2%). The numbers of patients with circumferential SSBE, round localized SSBE, and sharp localized SSBE were 38, 114 and 69, respectively. Round and sharp types of localized SSBE were simultaneously observed in 25 patients. Reflux esophagitis was more frequently observed in subjects with BE, regardless of type, in comparison to those without BE. Round localized SSBE was found mainly in the left posterior wall of the esophagus in a location similar to the main area of the esophageal cardiac glands. In contrast, sharp localized SSBE was observed mainly in the right anterior wall of the esophagus in a location similar to that of esophageal mucosal injury caused by mild type reflux esophagitis. Conclusion The location differs between round and sharp localized SSBE, possibly due to differences in the process of BE development.

Abstract
BACKGROUND Superficial Barrett's esophageal adenocarcinoma (s-BEA) in Barrett's esophagus frequently occurs in the right wall of the esophagus. Our aim was to examine the correlation between the location of s-BEA and the direction of acid and non-acid reflux in patients with Barrett's esophagus. PATIENTS AND METHODS We performed 24-h pH monitoring in 33 s-BEA patients using a pH catheter with eight sensors. One sensor was located at the 6 o'clock position in the lower esophagus and sensors 1 - 8 were arranged counterclockwise at the same level. The catheter was positioned at the same level as the s-BEA. We measured the maximal total duration of acid (MTD-A) and non-acid (MTD-NA) reflux. When the direction of MTD-A and MTD-NA coincided with the location of the s-BEA, the case was defined as coincidental and we calculated the rate of coincidence, and the probability of the rate of coincidence was estimated with 95 % confidence intervals (95 %CI). RESULTS Among the 33 cases of s-BEA examined, the rate of coincidence of both MTD-A and MTD-NA was 24/33 (72.7 %) (95 %CI 0.54 - 0.87). The rate of coincidence of either MTD-A or MTD-NA was 30/33 (90.9 %) (95 %CI 0.76 - 0.98). CONCLUSIONS Our study revealed that the location of s-BEA mostly corresponds to the direction of MTD-A or MTD-NA. Accurate observation of the distribution of acid or non-acid reflux by pH monitoring would aid early detection of s-BEA by endoscopy.

Abstract
BACKGROUND AND STUDY AIMS Mallory-Weiss tears (MWTs) are not only a common cause of acute nonvariceal gastrointestinal bleeding but also an iatrogenic adverse event related to endoscopic procedures. However, changes in the clinical characteristics and endoscopic features of MWTs over the past decade have not been reported. The aim of this study was to investigate recent trends in the etiology and endoscopic features of MWTs. PATIENTS AND METHODS We retrospectively reviewed the medical records of patients with a diagnosis of MWT at our university hospital between August 2003 and September 2013. The information regarding etiology, clinical parameters, endoscopic findings, therapeutic interventions, and outcome was reviewed. RESULTS A total of 190 patients with MWTs were evaluated. More than half (n = 100) of the cases occurred during endoscopic procedures; cases related to alcohol consumption were less frequent (n = 13). MWTs were most frequently located in the lesser curvature of the stomach and right lateral wall (2 - to 4-o'clock position) of the esophagus, irrespective of the cause. The condition of more than 90 % of the patients (n = 179) was improved by conservative or endoscopic treatment, whereas 11 patients (5.8 %) required blood transfusion. Risk factors for blood transfusion were a longer laceration (odds ratio [OR] 2.3) and a location extending from the esophagus to the stomach (OR 5.3). CONCLUSIONS MWTs were frequently found on the right lateral wall (2 - to 4-o'clock position) of the esophagus aligned with the lesser curvature of the stomach, irrespective of etiology. Longer lacerations extending from the esophagus to the gastric cardia were associated with an elevated risk for bleeding and requirement for blood transfusion.

Abstract
The prevalence rates of Barrett's esophagus (BE) and esophageal adenocarcinoma (EAC) arising from BE show striking geographic patterns as they are much more common in Western as compared with Asian countries. However, recent epidemiological studies indicate that the number of patients with BE and EAC are gradually increasing in Asia including Japan, corresponding to the increase in prevalence of gastroesophageal reflux disease (GERD). Because the prognosis of patients with advanced-stage EAC remains poor, early detection of neoplastic lesion in those with BE has led to recent interest in effective treatment. Several promising studies have revealed that early neoplasia in BE is mainly located in the right anterior wall of the distal esophagus. Interestingly, this endoscopic characteristic has been found in both Western and Japanese populations. Potential pathophysiologic explanations underlying the circumferential distribution of neoplasia in BE include a nonuniform asymmetric distribution of esophageal acid exposure, with a tendency toward mucosal acid-related injury on the right side of the esophageal wall in patients with GERD, and the functional structure of the lower esophageal sphincter. Findings of the present study should improve lesion detection and aid in developing a target biopsy protocol for surveillance of BE.

Abstract
OBJECTIVE The role of esophageal cardiac glands has not been fully determined. This study was performed to clarify the protective role of esophageal cardiac glands against the development of gastroesophageal reflux disease (GERD). METHODS The subjects included 2,656 Japanese individuals who visited our institution for a detailed medical checkup. GERD symptoms were assessed using the Japanese version of the Carlsson-Dent self-administered questionnaire (QUEST) and an upper gastrointestinal endoscopy examination in each subject. The presence of reflux esophagitis, size of diaphragmatic hiatus, degree of gastric mucosal atrophy and existence of visible esophageal cardiac glands in the distal esophagus, based on the detection of yellowish elevated areas, were determined using endoscopy. RESULTS Esophageal cardiac glands were observed in 355 cases (13.4%). Reflux esophagitis was significantly less frequent in the cases with esophageal cardiac glands than in those without. The esophageal cardiac glands were mainly located on the left-posterior side of the esophageal wall of the distal esophagus. A multiple regression analysis showed that the presence of esophageal cardiac glands was an independent factor for preventing reflux esophagitis. On the other hand, the existence of these glands did not correlate with the presence of GERD symptoms (QUEST score of 6 or more). CONCLUSION The presence of visible esophageal cardiac glands may have a protective role against the development of reflux esophagitis.

Abstract
BACKGROUND AND AIM The function of the lower esophageal sphincter (LES) is evaluated using an esophageal manometric study. However, information regarding the surrounding organs is difficult to obtain with use of a sensor catheter. We investigated the utility of 320-row area detector computed tomography (CT) to evaluate morphological changes of the esophagogastric junction and surrounding organs. METHODS The study subjects were 18 healthy volunteers and 29 patients with reflux esophagitis (RE). Immediately after swallowing a diluted contrast agent, continuous imaging of the esophagogastric junctional area was performed for 15 s. Using CT images, the presence or absence of esophageal hiatal hernia, His angle before and after swallowing, size of the diaphragmatic hiatus, morphologically identified-LES (MI-LES) length, intraluminal horizontal area of MI-LES during relaxation phase, MI-LES thickness, abdominal esophagus length, subcutaneous fat area, visceral fat area, and esophagogastric junction fat area were evaluated. RESULTS Analysis of CT images showed more frequent occurrence of hiatal hernia, greater His angle, and a larger diaphragmatic hiatus in patients with severe RE, while the lengths of MI-LES and abdominal esophagus were shorter in those patients. Visceral and esophagogastric junction fat areas tended to be greater in patients with RE. In all subjects, the posterior wall of the MI-LES was thicker than the anterior wall. CONCLUSION Continuous imaging with 320-row area detector CT is useful to evaluate morphological changes in the esophagogastric junction area in both normal individuals and patients with reflux esophagitis.

Abstract
Background/Aims Esophagogastric junctional lesions, such as mucosal breaks with Los Angeles grade A or B reflux esophagitis, lacerations in Mallory Weiss syndrome, and short segment Barrett's esophagus, are mainly found in the right anterior wall of the distal esophagus. Asymmetrical lower esophageal sphincter pressure and resting radial asymmetrical acid reflux may be causes of this asymmetrical distribution of reflux esophagitis and short segment Barrett's esophagus. We developed a novel pH and pressure catheter to investigate the asymmetrical distributions of pH and intra-esophageal pressure in the distal esophagus. Methods One healthy male volunteer was enrolled in this study. Acid reflux and motor function in distal esophagus was investigated using simultaneous measurements of intra-esophageal pH and pressure in 8 directions with novel sensor catheter. Results Thirty-six acid and weak acid reflux events were observed, of which 22 were circumferential refluxes with pH drops in all channels and 14 were partial refluxes with pH drops in some channels. Increase in transient circumferential intraesophageal pressure was observed just after 72.7% of the circumferential reflux and 42.9% of the partial reflux events. Conclusions Using a novel sensor catheter, 2 different types of acid reflux events were identified in the present study.
