To evaluate the usefulness of colonoscopy for the detection of ileal involvement in patients with intestinal follicular lymphoma, seventeen patients with intestinal follicular lymphoma who underwent colonoscopy and biopsy sampling from the terminal ileum were enrolled. The patients were divided into 2 groups: cases with ileal involvement (n=6) and cases without ileal involvement (n=11). Patients' clinical backgrounds were compared between the two groups. Subsequently, 10 board-certified endoscopists independently evaluated the endoscopic pictures and determined whether the ileum was involved with follicular lymphoma. Infiltration of follicular lymphoma cells were identified in 6 patients (35.3%). Cases with positive ileal involvement were diagnosed with follicular lymphoma at a younger age than were cases without ileal involvement (55.4±7.4 vs. 68.1±10.3 years, p=0.011). Macroscopically, in patients with ileal involvement, there were multiple polypoid elevations smaller than 5 mm in 4 cases, single polypoid elevation smaller than 5 mm in 1 case, and single polypoid elevation larger than 5 mm in 1 case. In patients without ileal involvement, there were no lesions in the terminal ileum in 7 cases, and multiple polypoid elevations smaller than 5 mm were seen in 4 cases. The accuracy of the macroscopic evaluation by 10 board-certified endoscopists was 68.8%. Colonoscopy is particularly recommended during the initial workup of patients with follicular lymphoma diagnosed at age ≤ 60 years. The diagnosis of ileal involvement based on morphology alone is difficult; thus, biopsy and pathologic diagnosis are required for accurate diagnosis.

BACKGROUND AND STUDY AIMS : Patients receiving antithrombotic drugs have a higher risk of postoperative bleeding and thromboembolic events related to endoscopic procedures. The aim of this study was to evaluate the relationship between various antithrombotic therapies and bleeding after gastric endoscopic submucosal dissection (ESD) (post-ESD bleeding). PATIENTS AND METHODS: Among 529 consecutive gastric ESD procedures (483 patients with 579 legions), 100 patients with 121 lesions who underwent 108 procedures were on antithrombotic therapy (group A) and 382 patients with 458 lesions who underwent 421 procedures were not on antithrombotic therapy (group B). The ratio of post-ESD bleeding between the two groups and the bleeding risk related to various antithrombotic therapies were investigated. RESULTS : Postoperative bleeding was more frequent in group A (11.1 %) than in group B (3.3 %). No thromboembolic events were reported in either group. Further investigation of antithrombotic therapies in group A demonstrated that various combinations of antithrombotic agents and heparin replacement were associated with a higher ratio of post-ESD bleeding. Multivariate analyses revealed that dual antiplatelet therapy (odds ratio [OR] 10.9, 95 % confidence interval [CI] 2.1 - 49.5; P = 0.005) and heparin replacement (OR 34.4, 95 %CI 9.4 - 133.2; P < 0.001) were associated with the increased risk of post-ESD bleeding. In patients on antiplatelet therapy, post-ESD bleeding tended to occur in the early postoperative period compared with patients on anticoagulant therapy. CONCLUSIONS: It is necessary to be cautious regarding post-ESD bleeding in patients requiring antithrombotic therapy, especially patients receiving dual antiplatelet therapy and heparin replacement. A further prospective study with a large sample will be needed to confirm these findings.

The purpose of this study was to investigate the endoscopic features of lanthanum deposition in the gastrointestinal mucosa. We retrospectively reviewed the endoscopic images of 10 patients who had received a histological diagnosis of lanthanum deposition in the gastroduodenal mucosa. The patients were 9 men and 1 woman with an average age of 64.3 years( range: 42 to 77 years). All patients were undergoing hemodialysis for chronic renal failure, and had been receiving lanthanum carbonate for 12 to 86 months. All patients had lanthanum deposition in the stomach, which presented as white lesions. Magnifying endoscopic observation, which was performed in six patients, also demonstrated the deposition of white microgranules. Three patients had lanthanum deposition in the duodenum, which manifested as white duodenal mucosa. In conclusion, lanthanum deposition in the gastroduodenal mucosa typically manifests as white lesions. Endoscopists should suspect lanthanum deposition when they detect white lesions in the gastroduodenal mucosa of patients who are taking lanthanum carbonate.

BACKGROUND: Polyethylene glycol (PEG) is widely used for bowel cleaning in preparation for colonoscopy because of its safety. Septic shock after PEG preparation is an extremely rare complication. Herein, we describe a case of septic shock that occurred immediately after colonoscopy preparation with PEG. CASE PRESENTATION: A 75-year-old Japanese male who had previously developed diabetes after total pancreatectomy received PEG in preparation for colonoscopy. He had been admitted to the emergency intensive care unit 4 days earlier due to hematochezia presenting with shock. He ingested PEG to prepare for a colonoscopy examination, which was performed to identify the source of his bleeding over a 5-h period, but suddenly exhibited septic shock and markedly elevated procalcitonin levels. A blood culture subsequently revealed Citrobacter braakii. Immediate resuscitation and intensive care with appropriate antibiotics improved his condition. CONCLUSIONS: Clinicians should be aware of the possibility of deteriorating conditions after bowel preparation with PEG among severely ill patients with recent episodes of hemorrhagic shock.

We retrospectively analyzed the cases of 14 patients (9 women, 5 men, mean age: 51.6 years) with cytomegalovirus (CMV) involvement in the esophagus, stomach, and/or duodenum diagnosed at a single center, to determine their endoscopic features and clinical backgrounds. Thirteen patients (92.9%) had hematologic disease; the other had rheumatoid arthritis. Of the former, 12 patients underwent allogeneic hematopoietic stem cell transplantation, and 9 of these patients had graft-versus-host disease (GVHD) before undergoing esophagogastroduodenoscopy (EGD). All 14 patients had been taking one or more immunosuppressive agents including cyclosporine (n=10), corticosteroids (n=9), mycophenolic acid (n=6), tacrolimus (n=3), and methotrexate (n=1). Tests for CMV antigenemia were positive in 11 patients (78.6%). EGD examinations revealed esophageal (n=3), gastric (n=9), and duodenal involvement (n=6). Macroscopically, esophageal lesions by CMV infection presented as redness (n=1), erosions (n=1), and ulcers (n=1). Gastric lesions manifested as redness (n=7), erosions (n=3), exfoliated mucosa (n=2), and verrucous erosions (n=1). Mucosal appearances in the duodenum varied: redness (n=2), ulcers (n=2), multiple erosions (n=2), single erosion (n=1), edema (n=1). CMV was detected even in the intact duodenal mucosa (n=1). In conclusion, physicians must recall the relevance of CMV infection when any mucosal alterations exist in the upper gastrointestinal tract of immunosuppressed patients.

BACKGROUND: The Japan Gastroenterological Endoscopy Society updated its guidelines for gastroenterological endoscopy in patients undergoing antithrombotic treatment in July 2012. However, the safety of endoscopic procedures in antithrombotic drug users has not been fully investigated. AIMS: To evaluate the safety of upper gastrointestinal endoscopic procedures in antithrombotic drug users. METHODS: From September 2013 to September 2015, patients who were taking antithrombotic drugs and who underwent upper gastrointestinal endoscopic procedures were prospectively enrolled at five hospitals. Incidences of bleeding and thrombosis during endoscopic procedures were evaluated. RESULTS: A total of 270 patients [221 for endoscopic mucosal biopsy and 49 for endoscopic mucosal resection (EMR)/endoscopic submucosal dissection (ESD) were enrolled. The bleeding rate was 0.9% for endoscopic mucosal biopsy and 22% for EMR/ESD, respectively. The bleeding rate after endoscopic mucosal biopsy was not significantly high, even if antithrombotic drugs were continued (0 vs. 1%, P > 0.99), while it was significantly higher among multiple antithrombotic drug users than single drug users (5.9 vs. 0%, P < 0.05). The bleeding rate after EMR/ESD was also higher among multiple antithrombotic drug users than single drug users, but was not significantly different (33 vs. 14%, P = 0.17). Moreover, there were no differences in bleeding rates according to the cessation or continuance of antithrombotic drugs (20 vs. 25%, P = 0.74). There were no thromboembolisms in all cases. CONCLUSIONS: Upper gastrointestinal endoscopic procedures performed under the new guidelines appear acceptable. However, endoscopic procedures among multiple antithrombotic drug users show a greater potential for bleeding.

BACKGROUND AND AIM: Video-capsule endoscopy (VCE) has shown that intestinal ulcers are common in non-steroidal anti-inflammatory drugs (NSAIDs) users, although the mechanisms and management have not been clearly defined. To explore the contribution of oxidative stress and potential of anti-oxidants for NSAIDs-induced intestinal ulcers, we assessed human serum oxidative stress balance and the effect of anti-oxidants using a mouse model. METHODS: A total of 30 NSAIDs users (17 aspirin and 13 non-aspirin users) received VCE. Serum reactive oxygen metabolite (d-ROM) and antioxidative OXY-adsorbent test (OXY) were measured. The indomethacin (IND)-induced mouse intestinal ulcer model was used to assess the effect of anti-oxidants. Eight-week-old mice were divided into four groups; control diet and diet including IND (N group), IND and L-carnitine (NC group), and IND and vitamin E (NE group). RESULTS: Serum OXY levels among non-aspirin users were lower in the mucosal injuries positive group than the negative group (P < 0.05). In the mouse models, the degree of mucosal injuries was lower in NC and NE than N (P < 0.01). Serum d-ROM levels were lower in NC and NE than N (P < 0.01), and OXY levels were higher in NC than N and NE (P < 0.01). The degeneration of intestinal mitochondria was mild in NC and NE. The serum KC/CXCL-1 level and hepatic expression of the anti-oxidant molecule Gpx4 were lower in NC than N. CONCLUSIONS: Non-aspirin NSAID-induced intestinal ulcers are related to decreased anti-oxidative stress function. Anti-oxidants, especially L-carnitine, are good candidates for intestinal ulcers.

A 68-year-old Japanese woman underwent radiotherapy for gastric lymphoma. Although lymphangiectasia was sparsely observed in the second portion of the duodenum before radiotherapy, the number of pinpoint white spots obviously increased after the treatment. Although the duodenal lymphangiectasia gradually progressed, the patient had no features of protein-losing enteropathy. This case highlights the importance of endoscopic observation of the duodenum after irradiation to the abdomen as radiotherapy may secondarily cause intestinal lymphangiectasia.

An 83-year-old Japanese man underwent esophagogastroduodenoscopy for screening purposes. He had a medical history of hypertension, chronic kidney disease, chronic heart failure, and chronic myeloid leukemia, and he had been taking the following medications:ferrous citrate, furosemide, spironolactone, tolvaptan, bisoprolol, nicorandil, warfarin, nilotinib, febuxostat, esomeprazole, digestive enzyme complex, ambroxol, carbocysteine, and potassium L-aspartate. Esophagogastroduodenoscopy revealed a brownish speckled pigmentation in the duodenal bulb. Biopsy specimens from the duodenal villi revealed a brown pigment deposition, which appeared bright on scanning electron microscopy. Energy dispersive X-ray spectroscopy and elemental mapping revealed the presence of iron and sulfur in the duodenal villi. Consequently, pseudomelanosis duodeni was diagnosed based on these findings.

Language：English

An 86-year-old Japanese man was presented to our hospital for further investigation of duodenal adenocarcinoma. The tumor was endoscopically resected. Pathological analysis revealed coexistence of gastric foveolar metaplasia and a surrounding hyperplastic Brunner's gland, in addition to an adenocarcinoma component. Immunostaining for MUC5AC and MUC6 confirmed the diagnosis of adenocarcinoma in situ arising from Brunner's gland hyperplasia. This case suggests that although detailed preoperative evaluation is required to determine the depth of tumor invasion, endoscopic resection may be a promising option for the treatment of adenocarcinomas arising from Brunner's gland hyperplasia.

Background and Aims. Gastrointestinal surveillance is a requirement prior to liver transplantation (LT), but small intestine examination is not generally undertaken. The aim of the present study was to evaluate the safety and efficacy of capsule endoscopy (CE) for patients with end-stage liver disease. Methods. 31 patients who needed LT were enrolled, and 139 patients who underwent CE over the same period of time acted as controls. Results. Frequency of successful achievement of evaluation of the full length of the small bowel, the mean gastric transit time, and the mean small bowel transit time were not significantly different between the two groups. Abnormalities in the small bowel were found in 26 patients. Comparative analysis revealed that history of EV rupture, history of EV treatment, red color sign of EV, and presence of PHG or HCC were significantly associated with patients with >2 two such findings (high score group). Conclusions. Small bowel examination by CE in patients before liver transplantation could be performed safely and is justified by the high rate of abnormal lesions detected particularly in patients with history of EV therapy or bleeding, red color sign, and presence of PHG or HCC. This study was registered in the UMIN Clinical Trial Registry (UMIN 000008672).

&emsp;Esophageal achalasia is a disorder of the lower esophageal sphincter muscle. Patients present with dysphagia, chest pain, vomiting, and aspiration. Esophageal achalasia had traditionally been treated with esophageal achalasia balloon dilatation and the Heller-Dor method, but in recent years, the use of per-oral endoscopic myotomy (POEM) has increased. Our patient, a 39-yr-old male, began experiencing dysphagia 4 years prior to his referral to our hospital. Based on the results of esophagogastroduodenoscopy, esophageal radiography and high-resolution manometry, we made the diagnosis of esophageal achalasia (Chicago classification type I) . After informed consent from the patient and his family and approval from our hospital's ethics committee were obtained, we performed a POEM. The patient was discharged on the 4th day post-surgery. At the 1-year post-operative examination, no worsening of symptoms and no relapse were observed. POEM is an excellent treatment method for esophageal achalasia from the perspective of therapeutic effect and prevention of invasion. We recommend that it be considered as the first-choice treatment for achalasia. However, accessibility to the procedure itself is limited due to the few adequately trained operators worldwide. POEM should thus be performed by an expert operator at a high-volume center.

A 58-year-old Japanese man visited a local clinic for the evaluation of a stomachache. He was diagnosed with intestinal obstruction. His medical history included a proctocolectomy at the age of 38 years, due to familial adenomatous polyposis (FAP). He was referred to our institution, where he underwent a computed tomography examination and endoscopy of the small intestine. The pathological diagnosis was adenocarcinoma. No invasive or metastatic lesions were observed. Therefore, partial resection of the ileum with lymphadenectomy and reconstruction of the ileostomy were performed. Pathological examination revealed that the tumor was type 2, pT3 (SS) , pN1, pPM0, pDM0, pRM0, INFb, ly1, v1, pEX0, PN0. Twenty-nine days after the surgery, the patient was diagnosed with lung metastasis and he underwent lung radiofrequency ablation. We suggest that long-term follow-up is necessary for patients after surgery for FAP, because of the risk of malignant disease developing in other organs.
