RESUMO
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. CONCLUSION: s 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.
RESUMO
Sporadic foveolar-type gastric adenoma (FGA) has been described as an extremely rare polyp that is whitish and flatly elevated. However, we recently found that sporadic FGA with a raspberry-like appearance (FGA-RA) is not rare in Helicobacter pylori (H. pylori)-naïve gastric mucosa. We endoscopically or surgically treated 647 patients with gastric epithelial neoplasms in the last 5 years, with 7.7% (50/647) being H. pylori-naïve. Among these, 43 FGA-RAs were diagnosed based on histologic and endoscopic features in 34 patients, who were all enrolled in this retrospective study. All lesions were observed by white-light endoscopy (WLE) and narrow-band imaging with magnification endoscopy (NBIME). We subsequently analyzed their endoscopic and microscopic features and patient characteristics. The patients were 22 males and 12 females aged 57±23 years (mean±2SD). WLE showed raspberry-like small polyps mimicking gastric hyperplastic polyps in the oxyntic gastric compartment (body/fundus). Multiple growths were confirmed in 20.6% (7/34) of the patients. NBIME revealed irregularly shaped papillary/gyrus-like microstructures with abnormal capillaries. Histologically, all lesions were intraepithelial neoplasms, and most of lesions (62.8%, 27/43) exhibited low-grade dysplasia. Immunohistochemically, neoplastic cells featured strong and diffuse MUC5AC expression, negative or very low MUC6 expression, and negative MUC2/CD10 expression. They also showed Ki-67 hyperexpression with a mean labeling index of 59.4±48.7%. The coexistence of fundic gland polyps in the background mucosa was significantly higher in multiple FGA-RA cases than in solitary cases (100% vs. 55.5%, P< 0.05). FGA-RA is a newly suggested histologic variant of sporadic FGA whose occurrence is not rare in daily endoscopic practice.

OBJECTIVE: Endoscopic submucosal dissection (ESD) for extensive esophageal cancer is sometimes associated with post-ESD stenosis, despite preventative steroid therapy. In this retrospective multicenter analysis, we evaluated the factors associated with therapy resistance. MATERIALS AND METHODS: We enrolled 73 patients with 75 extensive esophageal cancers treated with ESD. Stenosis prevention was performed using two esophageal triamcinolone acetonide (TA)-fillings, and repeated if stenosis was found on follow-up. Therapy-resistance factors associated with incidence of severe stenosis requiring endoscopic balloon dilation (EBD) were evaluated, including age, gender, previous treatment history, tumor location, morphology, resection size, histologic type, invasion depth, and horizontal resection grade (HR-grade 1, ≥â9/12 and <10/12 of the circumference; grade 2, ≥â10/12 and <11/12; grade 3, ≥â11/12 but not circumferential; and grade 4, entirely circumferential). RESULTS: Severe stenosis occurred in 17.3%(13/75) of cases, with a median of two EBDs (range, 1-6 times). Severe stenosis was significantly associated with HR-grade elevation and previous treatment history (p < .05); multivariate analysis showed both as independent therapy-resistance factors (p < .05). Patients without previous treatment history demonstrated severe stenosis at 12.9%(9/70): 0%(0/26) HR-grade 1, 18.8%(3/16) grade 2, 17.6%(3/17) grade 3, and 27.3%(3/11) grade 4, showing a risk of HR-grade 2 or more resection but an acceptable stenosis prevention even after entirely circumferential resection. Conversely, patients with previous treatment history demonstrated severe stenosis at a high frequency of 80%(4/5). CONCLUSIONS: Esophageal TA-filling is a promising stenosis-preventive steroid therapy, even in entirely circumferential ESD cases. However, HR-grade 2 or more elevation and previous treatment history were independently associated with therapy resistance.

BACKGROUND AND AIM: The esophageal triamcinolone acetonide (TA)-filling method is a novel local approach for stenosis prevention after extensive esophageal endoscopic submucosal dissection (ESD). We evaluated this method after subcircumferential ESD. METHODS: We enrolled 20 patients with esophageal cancer requiring subcircumferential ESD in a prospective multicenter study. Esophageal TA filling was carried out 1 day and 1 week after ESD, with follow-up endoscopy every 2 weeks. We treated severe stenosis preventing endoscope passage with endoscopic balloon dilatation (EBD) and additional TA filling, and mild stenosis allowing endoscope passage with additional TA filling only. Primary endpoint was incidence of severe stenosis; secondary endpoints were total number of EBD, rate of additional TA filling, time to stenosis and complete re-epithelialization, dysphagia score, and adverse events. Horizontal resection grade was divided into grades 1 (≥â9/12 and <10/12 of the circumference), 2 (≥â10/12 and <11/12), and 3 (≥â11/12 but not circumferential) and analyzed statistically for correlation with endpoints. RESULTS: Incidence of severe stenosis was 5.0% (1/20; 0.1-24.8%) and was treated with three EBD. Six patients showed mild stenosis. Additional TA filling was carried out in these seven patients: 0% (0/9) for grade 1 resection, 40% (2/5) for grade 2, and 83% (5/6) for grade 3 (P < 0.05). Median time to stenosis and re-epithelialization was 3 and 7 weeks, respectively. Dysphagia score deteriorated in one patient. No adverse events occurred. CONCLUSIONS: The esophageal TA-filling method prevented stenosis after subcircumferential ESD. Grade ≥2 resection showed a high risk for stenosis, but additional TA filling for mild stenosis inhibited stenosis progression (UMIN000024384).

Objective Acute cholangitis is occasionally life-threatening and requires immediate treatment. For the management of acute cases, globally accepted diagnostic criteria and the use of severity grading, as defined in the Tokyo Guidelines 2018 (TG18), are recommended. This study was performed to explore the association between acute cholangitis and the level of adenosine 5'-triphosphate (ATP) in blood as determined with a simple measurement method. Methods Twenty-three consecutive patients admitted for acute cholangitis and 14 healthy individuals were enrolled. Based on the TG18, the patients were categorized according to the degree of severity as Grade I, II, or III. We measured the amount of ATP in blood samples using a bioluminescence meter and evaluated the correlation with the degree of severity. Results The ATP/total hemoglobin (tHgb) level showed a significant decline in association with an increase in severity, as that in the healthy controls was 236.60 ± 8.10 and in the Grade I, II, and III groups was 238.56 ± 6.98, 186.88 ± 7.62, and 154.60 ± 11.01, respectively (p<0.01). While no significant difference was observed between the healthy controls and Grade I patients (p=0.649), there was a statistically significant difference between Grade I and Grade II (p<0.01) in the ATP/tHgb level. According to a receiver operating characteristic analysis, the area under the curve for ATP/tHgb, used as an index for predicting the need for emergency biliary drainage (Grade II, III cases), was the highest among various examined factors. Conclusion The present novel measurement method was found to be simple to perform and useful for detecting acute cholangitis patients with a low ATP level who may require emergency biliary drainage.

A diagnosis of tuberculous peritonitis (TBP) is difficult because of nonspecific manifestation and limited effectiveness of conventional diagnostic tools. Recently, the usability of measurement of ascitic adenosine deaminase (ADA) was shown. We report here a case of TBP in which measurement of ascitic ADA contributed to the diagnosis. A 93-year-old male developed a large amount of ascites. Analyses of the ascitic fluid revealed exudation, though antibiotics treatment was ineffective. Using paracentesis, the ADA level in the ascites was measured and shown to be high. Under suspicion of TBP, an exploratory laparoscopy was performed and a definitive diagnosis of TBP was made.
RESUMO
Background and study aims Foveolar-type adenoma is described as a very rare tumor that occurs in individuals without Helicobacter pylori (HP) infection and diagnosed as adenocarcinoma in the Japanese Classification of Gastric Carcinoma (JCGC). However, we have frequently encountered patients with foveolar-type adenoma that endoscopically resembles a hyperplastic polyp, suggesting that it has just been overlooked to date. Here, we analyzed clinicopathological characteristics of a special subtype of foveolar-type adenoma showing specific endoscopic findings. Patients and methods From a total of 212 patients with gastric cancer resected during a 22-month period, we enrolled 14 (6.6â%) diagnosed with foveolar-type adenoma (adenocarcinoma in JCGC). HP infection status was determined by eradication history, HP serum IgG antibody level, urea breath test, and endoscopic and histological findings. All lesions were observed using white-light endoscopy and narrow-band imaging with magnification endoscopy (NBIME). Endoscopically resected lesions were histologically examined. Results None of 14 patients had a current or past history of HP infection. All lesions were visualized on non-atrophic gastric mucosa as small reddish protrusions with fine granular surface, showing a raspberry-like appearance. NBIME showed papillary or gyrus-like microstructures with irregular capillary. Lesions were histologically diagnosed as foveolar-type adenoma showing MUC5AC-positive gastric mucin phenotype. Ki-67 was overexpressed (median labeling index 69.9â%, range 28.4â-â92.1â%), though all lesions were an intraepithelial tumor without stromal invasion. p53 over-staining was not seen in any. Conclusions Raspberry-like lesions on non-atrophic gastric mucosa in HP-uninfected individuals should be evaluated for the possibility of a special subtype of foveolar-type adenoma.
RESUMO
As a rarely recognized foreign body in the upper gastrointestinal tract, rice cake frequently requires endoscopic removal. We herein report six patients with characteristic sonography, computed tomography (CT), spectroscopy, endoscopy, and histological findings. A review of all published cases, including ours, revealed that retained rice cake in the stomach typically shows the following: abdominal pain (93.3%), mucosal injury (93.3%) with bleeding (42.9%); high-density (120-206 Hounsfield units) CT findings; and indication for endoscopy (80%). In the esophagus, hot, toasted rice cake causes thermal injury. Primary physicians should be aware of this popular-food-induced, but rare, disorder.

Eosinophilic esophagitis (EoE) is an allergic inflammatory disorder that is characterized clinically by symptoms related to esophageal dysfunction and histologically by eosinophil-predominant inflammation.1,2 Its prevalence has been increasing rapidly in both Western and Asian countries. In Japan, most of the cases of esophageal eosinophilia (EE) are found in an upper endoscopy examination for gastric cancer screening performed during a comprehensive health check-up.3,4 Indeed, we frequently encounter patients with asymptomatic EE showing typical endoscopic findings, such as linear furrows, as well as histologic findings compatible with EoE. However, the current clinical guidelines for EoE diagnosis include symptoms related to esophageal dysfunction, thus patients without symptoms do not fulfill the diagnostic criteria.1,2 The clinical characteristics remain to be fully elucidated,5 thus we aimed to clarify clinical features of asymptomatic EE as compared with those of EoE.

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.

We successfully treated a 22-year-old woman with eosinophilic gastroenteritis (EGE) using a multiple food-elimination diet. The patient was diagnosed with EGE based on histopathological findings and initially treated with oral prednisolone. The symptoms immediately improved, although they recurred when prednisolone was tapered to a low dose. We then treated her with a multiple food-elimination diet, including milk, soy, eggs, wheat, nuts, seafood, and rice. During dietary treatment, we identified dairy products and eggs as causative foods of the symptoms, and we ceased prednisolone. Similar to eosinophilic esophagitis, an elimination diet may be effective for adult patients with EGE.

BACKGROUND/AIMS: The novel prokinetic drug acotiamide is used for treatment of functional dyspepsia. It is still unclear how acotiamide has effects on esophageal motor function. Esophageal peristalsis and esophagogastric junction (EGJ) compliance has an important role for prevention of esophageal mucosal damage caused by gastroesophageal reflux, however, few studies have analyzed the effects of acotiamide on those former activities and none have investigated its effects on EGJ compliance. The aim of our research was to examine the effects of acotiamide on esophageal motility and EGJ compliance. METHODS: We enrolled 3 gastroesophageal reflux disease (GERD) patients as well as 9 healthy volunteers. Using high-resolution manometry, we examined esophageal motor activity parameters, including esophageal body contractions and lower esophageal sphincter (LES) pressure. While, EGJ compliance was evaluated using a functional lumen imaging probe. Following determination of baseline values for esophageal motor activities and EGJ compliance, acotiamide at a standard dose of 300 mg/day was administered for 3 days. All measurements were performed again 2 hours after the last acotiamide administration. RESULTS: In the healthy volunteers, as compared with the baseline values, acotiamide administration did not significantly change esophageal body contractions and LES pressure. And EGJ distensibility was not significantly changed (distensibility index in 40-mL distension: 3.5 ± 0.4 vs 3.3 ± 0.5 mm²/mmHg). Similarly in the GERD patients, there were no differences in either esophageal motility or EGJ compliance between before and after acotiamide administration (distensibility index in 40-mL distension: 6.2 ± 0.5 vs 6.5 ± 1.1 mm²/mmHg). CONCLUSION: In both healthy individuals and GERD patients, standard dose acotiamide dose does not have significant effects on esophageal motor activities or EGJ compliance.
RESUMO
BACKGROUND AND STUDY AIMS: Characteristic endoscopic findings, such as linear furrows, rings, and whitish exudates, indicate the presence of esophageal eosinophilia (EE), though no specific findings are known to distinguish eosinophilic esophagitis (EoE) from proton pump inhibitor-responsive esophageal eosinophilia (PPI-REE). Here, we present a novel endoscopic finding in some EE patients possessing a linear longitudinal arrangement of whitish nodules with the appearance of the back of an Ankylosaurus dinosaur, termed Ankylosaurus back sign (ABS), and evaluations of its significance in affected patients. PATIENTS AND METHODS: Fifty-five patients diagnosed with EE (≥â15 eosinophils/high power field) who were treated at our hospital and shown to evaluate a PPI response were enrolled. Endoscopic findings at baseline and clinical parameters were retrospectively reviewed. Furthermore, the clinicopathological features of patients with ABS, as well as the relationship between its presence and PPI response were evaluated. RESULTS: Fifty-five patients (47 males, 8 females) with EE (17 with EoE, 38 with PPI-REE) were evaluated, of whom 50 (90.9â%) had linear furrows, the most frequently found feature, while ABS was found in 9 (16.4â%). Inter-observer agreement was substantial for ABS (κ 0.77). Interestingly, all patients with ABS had PPI-REE. Our findings revealed that the presence of ABS was closely associated with reflux esophagitis (RE) in patients with PPI-REE. CONCLUSIONS: Although ABS was less frequent than typical endoscopic findings such as linear furrows in EE, this novel finding was closely associated with PPI-REE accompanied with RE. The clinical implications of ABS in patients with EE should be investigated further.
RESUMO
BACKGROUND AND AIMS: Endoscopic submucosal dissection (ESD) for extensive esophageal carcinomas may cause severe stenosis requiring endoscopic balloon dilations (EBDs). A standard prevention method has not been established. We propose the esophageal triamcinolone acetonide (TA)-filling method as a novel local steroid administration procedure. METHODS: We enrolled 22 consecutive patients with early esophageal cancer who were treated using either subcircumferential or circumferential ESD (15 and 7 procedures, respectively) in this case series. Esophageal TA filling was performed on the day after ESD and 1 week later and was performed again if mild stenosis was found on follow-up. EBD with TA filling was performed only for severe stenosis that prevented endoscope passage. The primary endpoint was the incidence of severe stenosis. Secondary endpoints were the total number of EBDs and additional TA filling, dysphagia score, time to stenosis and to complete re-epithelialization, and any adverse events. RESULTS: The incidence of severe stenosis was 4.5% (1/22; confidence interval, .1%-22.8%), and EBD was performed 2 times in 1 patient. Mild stenosis was found in 9 patients. Additional TA filling was performed in 45.5% of patients (10/22; median, 5 times; range, 1-13). The dysphagia score deteriorated to 1 to 2 in 31.8% (7/22) but showed a final score of 0 after complete re-epithelialization in 90.9% (20/22). The median time to stenosis was 3 weeks (range, 3-4) and that to complete re-epithelialization was 7 weeks (range, 4-36). No severe adverse events occurred. CONCLUSIONS: The esophageal TA-filling method is highly effective for preventing severe stenosis after extensive esophageal ESD.

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.âThe 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 (72.8â%) had the same LA grade at recurrence. In addition, recurrent mucosal breaks in 96 (84.2â%) patients were observed to have occurred in the same circumferential location as at the initial diagnosis, while those in 18 (15.8â%) were observed in a different location. When recurrent lesions had a different location, the LA grade also tended to be different (Pâ=â0.02). 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.
RESUMO
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.

BACKGROUND: Esophageal eosinophilia is classified as either eosinophilic esophagitis (EoE) or proton-pump inhibitor-responsive esophageal eosinophilia (PPI-REE), depending on the response to PPI treatment. The aim of this study was to compare the clinical, endoscopic, and histopathological findings of EoE and PPI-REE in Japanese patients. In addition, the characteristics of these cases were compared with those of reflux esophagitis (RE) cases. METHODS: Eleven patients diagnosed with EoE, 16 with PPI-REE, and 39 with RE, who were all consecutively examined from 2005 to 2015 at Shimane University Hospital, were enrolled. Clinical, endoscopic, and histopathological esophageal findings in these groups were retrospectively examined and compared. RESULTS: The differences in the clinical characteristics of EoE and PPI-REE were not remarkable, though patients with EoE and PPI-REE were younger, presented a higher prevalence of allergic comorbidities, and complained of symptoms of dysphagia more frequently than those with RE. The only noteworthy differences between EoE and PPI-REE were more frequent reports of asthma (36.4 vs. 2.6 %) and food allergy (27.3 vs. 0 %) by patients with EoE (P < 0.05, P < 0.05, respectively). Endoscopic findings in patients with EoE and PPI-REE were similar, with the presence of esophageal erosions in a small percentage of PPI-REE cases being the only difference. There were no histopathological differences between EoE and PPI-REE. CONCLUSIONS: Comparisons of clinical, endoscopic, and histopathological findings between EoE and PPI-REE showed that these two types have similar characteristics, though EoE patients showed a higher atopic background. Predicting PPI responsiveness in cases with esophageal eosinophilia is difficult and requires further investigation.

We occasionally encounter patients with various types of rectal foreign bodies. When too large to grasp, transanal removal can be difficult. Here, we report a case of successful manual transanal removal of an 18 × 4 × 4 cm silicon rod without complications. A 50-year-old male came to the emergency department of our hospital 12 h after transanal insertion of a whole silicon rod. An abdominal examination showed no evidence of peritonitis, while X-ray and computed tomography findings revealed a large foreign body in the rectum, without any sign of perforation. Initially, we attempted removal using an endoscopy procedure with conventional endoscopic instruments, including a snare and grasp forceps, though we failed because of the large size. Next, we manually compressed the foreign body from the abdominal wall under endoscopic and X-ray fluoroscopic observation, and successfully removed it in a transanal manner without complications. Endoscopic and X-ray fluoroscopic assistance were helpful to guide the direction and angle of abdominal compression in this case.
