The aim of this study is to evaluate the application of microstructural and microvascular patterns in recognizing gastric MALToma on magnifying endoscopy. METHOD: All patients with diagnosis of gastric MALToma upon histology were recruited. They received magnifying endoscopy to observe for changes in microstructural and microvascular patterns. For patients with H pylori, eradication therapy would be given. For those without, appropriate treatments including gastrectomy or chemotherapy were commenced accordingly. Patients treated with H pylori eradication and non-operative treatments received follow-up magnifying endoscopy, and the same features were observed to predict the response to these treatments. RESULTS: From 2004 to 2007, nine patients presented to with epigastric pain, dyspepsia and belching. All patients were confirmed to have MALToma upon initial biopsy. Five patients had H pylori infection and received eradication. Two patients without H pylori were treated with Laparoscopic total gastrectomy. Two patients had pulmonary metastasis and treated with chemotherapy. Under magnifying endoscopy, all the lesions demonstrated either absence or irregular gastric pits. Moreover, there was consistently appearance of spider-shaped vascular pattern. Five patients with H pylori eradication had follow-up magnifying endoscopy, four of them showed resolution of abnormal vascular pattern and recovery of gastric pits. CONCLUSION: Abnormal spider like vasculature and disappearance of gastric pits are diagnostic features upon magnifying endoscopy for gastric MALToma. These features enhanced the diagnosis and assessment of extent of involvement during primary endoscopy, as well as follow-up surveillance for response to non-operative treatments.</p>","PeriodicalId":89416,"journal":{"name":"Journal of interventional gastroenterology","volume":"2 1","pages":"3-7"},"PeriodicalIF":0.0,"publicationDate":"2012-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3350901/pdf/jig0201_0003.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"30617930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Applicability in non-veteran community settings in the United States (U.S.) has not been reported. AIMS: Our aim is to perform a pilot study to establish feasibility of use the water method at 2 community sites. We tested the hypothesis that compared with air insufflation patients examined with the water method would require less sedation without adverse impact on outcomes. METHODS: Two performance improvement projects were carried out. Consecutive patients who consented to respond to a questionnaire after colonoscopy were enrolled. Project 1: The design was single-blinded (patient only); quasi-randomized - odd days (water), even days (air). Colonoscopy was performed by a staff attending. Project 2: A supervised trainee performed the reported procedures. In both, patient demographics (age, gender and body mass index), amount of sedation required during colonoscopy and procedure-related variables were recorded. The patients completed a questionnaire that enquired about discomfort during colonoscopy and willingness to repeat the procedure within 24 hours after the procedure. RESULTS: Project 1: Significantly lower doses of fentanyl and midazolam were used and a higher adenoma detection rate (ADR) was demonstrated in the water group. Project 2: 100% cecal intubation rate was achieved by the supervised trainee. CONCLUSION: This is the first pilot report in the U.S. documenting feasibility of the water method as the principal modality to aid colonoscope insertion in both male and female community patients. In a head-to-head comparison, significant reduction of sedation requirement is confirmed as hypothesized.
