抄録 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.

タイトル(別表記) Adenocarcinoma in the jejunum 20 years after surgery for familial adenomatous polyposis

抄録 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.

抄録  Most gastric bezoars can be treated with endoscopic fragmentation combined with or without cola dissolution, whereas laparotomy or laparoscopic surgery is generally inevitable for small intestinal bezoars because they cause small bowel obstruction. Therefore, early diagnosis and management of gastric bezoars are necessary to prevent bezoar-induced ileus. To investigate the incidence of overlooked gastric bezoars during the initial esophagogastroduodenoscopy, we retrospectively reviewed the cases of 27 patients diagnosed with gastrointestinal bezoars. The bezoars were diagnosed using esophagogastroduodenoscopy (n=25), abdominal ultrasonography (n=1), and barium follow-through examination (n=1). Bezoars were overlooked in 9/25 patients (36.0%) during the initial endoscopy examination because the bezoars were covered with debris in the stomach. Of the 9 patients, 8 had concomitant gastric ulcers, and the other patient had gastric lymphoma. Although a computed tomography (CT) scan was performed before the second-look endoscopy in 8 of the 9 patients, the bezoars were mistaken as food debris on CT findings and were overlooked in these patients. In conclusion, gastric bezoars may not be discovered during the initial esophagogastroduodenoscopy and CT scan. In cases with debris in the stomach, second-look endoscopy is essential to detect bezoars.

抄録 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.

タイトル(別表記) Changes of colonic mucosa caused by long-term use and discontinuation of anthraquinone
著者 岩野 英二| 岩室 雅也| 岡田 裕之|
抄録 Anthraquinone, an anthracene derivatives, is widely used as a purgative medicine. The long-term use of anthraquinone is known to cause melanosis coli and elevated lesions in the colon. However, the clinical course of patients who take anthraquinone over a long term and those who discontinue the drug has not been fully investigated. Here we investigated 22 patients who had colonic mucosal changes ( i.e., melanosis coli and elevated lesions) who had been taking anthraquinone for at least one year and discontinued it. We classified the elevated lesions into two subtypes:the small-lesion, which included multiple small nodules that were < 2 mm in dia., and the large-lesion, which included a single or multiple nodules of ≥ 2-mm dia. We used colonoscopy to investigate the changes of colonic lesions between before and after the discontinuation of anthraquinone. The results indicated that the nodules of the small-lesion group were lymphoid follicle hyperplasia. In the large-lesion group, adenoma was most frequently observed ( n=118) , followed by hyperplastic polyp ( n=52) and inflammatory changes with edema ( n=22) . Melanosis coli and elevated lesions were decreased or invisible after the discontinuation of anthraquinone. Our findings thus suggest that the long-term use of anthraquinone may cause some type of elevated lesions due to chronic inflammation. It is recommended that the use of anthraquinone be limited to a short term.

抄録 The usefulness of endoscopy in marginal ulcer bleeding has rarely been studied, and the optimal method for preventing rebleeding is unclear. Here we assessed the efficacy of endoscopy in marginal ulcer bleeding and examined the efficacy of proton pump inhibitors (PPIs) in the prevention of rebleeding. A total of 28 patients with marginal ulcer bleeding (21 men, 7 women; median age 58.5 years) were treated by endoscopy. We analyzed the clinical characteristics, results of endoscopic therapy, characteristics of rebleeding patients, and relation between the use of PPIs and the duration of rebleeding. Sixteen patients had active bleeding. Initial hemostasis was achieved in all patients. There were no procedure-related adverse events. Rebleeding occurred in one patient within the first month and in 7 patients thereafter. There was a significant difference in the rebleeding rate between the patients who received a PPI and those who did not. In a multivariate analysis, the non-use of PPIs was a risk factor for rebleeding (hazard ratio, 6.22). Therapeutic endoscopy is effective in achieving hemostasis from marginal ulcer bleeding. PPIs may prevent rebleeding from marginal ulcers.
