RESUMEN

BACKGROUND/AIMS: Current guidelines recommend withholding antiplatelets for 5–7 days before high-risk endoscopic procedures. We investigated whether this reduces post-endoscopic submucosal dissection (ESD) bleeding. METHODS: Gastric ESD cases with antiplatelets were retorospectively reviewed. Withholding antiplatelets for 5–7 days before ESD was defined as cessation and 0–4 days as continuation. The rate and risk of post-ESD bleeding according to the types and cessation of antiplatelets were assessed. RESULTS: Among the 215 patients (117 adenoma and 98 early gastric cancer), 161 patients were on single (94 aspirin, 56 thienopyridine, and 11 other agents), 51 on dual, and 3 on triple antiplatelets. Post-ESD bleeding rates were 12.8% in aspirin users, 3.6% in thienopyridine, 27.5% in dual, 33.3% in triple therapy, and 9.7% in the cessation and 15.0% in the continuation group. Multiple antiplatelets (odds ratio [OR], 2.41; 95% confidence interval [CI], 1.01 to 5.76) and specimen size ≥ 5.5 cm (OR, 2.84; 95% CI, 1.04 to 7.73) were the risk of bleeding, while continuation of thienopyridine (OR, 0.23; 95% CI, 0.05 to 1.09) and antiplatelets (OR, 1.83; 95% CI, 0.68 to 4.94) did not increase the risk of bleeding. CONCLUSIONS: Continuing thienopyridine and aspirin did not increase the risk of post-ESD. Multiple antiplatelet therapy and a large specimen size were independent risk factors of post-ESD bleeding.

RESUMEN

BACKGROUND/AIMS: Gastric mucosal atrophy and intestinal metaplasia due to Helicobacter pylori infection are the main precursor lesions of gastric cancer. The aim of this study was to evaluate the long-term effects of H. pylori eradication on the progression of precancerous lesions to metachronous cancer after endoscopic resection of early gastric cancer (EGC). METHODS: Patients who underwent endoscopic resection of EGC were retrospectively reviewed. Changes in precancerous lesions and development of metachronous cancer were compared according to H. pylori eradication and final infection status. RESULTS: In total, 565 patients were followed for over 5 years after endoscopic resection of EGC. The grade of atrophy on corpus was significantly lower in the H. pylori-eradicated group than in the persistent group during follow-up (p=0.029). In patients < 70 years of age, the cumulative incidence rate of metachronous cancer was significantly lower in the H. pylori-eradicated group than in the persistent group (p=0.018). Age was an independent risk factor for metachronous cancer development. CONCLUSIONS: H. pylori eradication might prevent the development of metachronous cancer in patients < 70 years of age by delaying the progression of precancerous lesions after endoscopic resection of EGC.

RESUMEN

Herein, we report a rare case of concurrent gastric and pulmonary mucosa-associated lymphoid tissue (MALT) lymphomas. A 65-year-old man who had been diagnosed with Helicobacter pylori-positive gastric MALT lymphoma received eradication therapy and achieved complete remission. During follow-up, he developed de novo pulmonary MALT lymphoma as a sequela of pulmonary tuberculosis, accompanied by recurrent gastric MALT lymphoma. Polymerase chain reaction (PCR) products of the CDR3 region of the immunoglobulin heavy chain gene showed an overall polyclonal pattern with bands at 400 base pairs (bp) and 200 bp predominant in the pulmonary tissue, as well as two distinctive bands in the gastric tissue at 400 bp and 200 bp. This case suggests that multiorgan lymphomas are more likely to be independent from each other when they are far apart, involve different organ systems, and have independent precipitating factors.

RESUMEN

BACKGROUND/AIMS: Proton pump inhibitors (PPIs) are widely used in the treatment of gastroesophageal reflux disease (GERD). However, some patients fail to respond to PPI therapy. We investigated the efficacy of response to PPI therapy in patients with GERD symptoms. METHODS: A total of 179 subjects with GERD symptoms were prospectively enrolled and diagnosed with non-erosive reflux disease (NERD, n = 100) and erosive reflux disease (n = 79) by gastroscopy and Bernstein test and/or 24-hour esophageal pH testing. Subjects then received a standard dose of daily PPI therapy for at least 4 weeks. PPI therapy response was evaluated using questionnaires including questions about demographics, GERD symptoms, GERD impact scale, Epworth sleepiness scale, Pittsburgh sleep quality index (PSQI), hospital anxiety and depression scale, and abbreviated version of the World Health Organization quality of life scale. RESULTS: The rates of complete (> or = 80%), satisfactory (> or = 50%), partial (< 50%), and refractory response in the 179 participants were 41.3%, 30.2%, 18.4%, and 10.1%, respectively. Thus, overall response rate (complete and satisfactory responses) was 71.5%. Multivariate analysis showed body mass index < 23 kg/m2 (OR, 2.20; 95% CI, 1.12-4.34), higher total PSQI score (OR, 1.20; 95% CI, 1.05-1.35), history of psychotherapy or neuropsychiatric medication (OR, 2.44; 95% CI, 1.23-4.85), and NERD (OR, 3.30; 95% CI, 1.54-7.11) were associated with poor response to PPI therapy. CONCLUSIONS: Psychological factors, sleep dysfunction, body mass index < 23 kg/m2, and NERD seem to be the major factors that lead to a poor response to PPI treatment in patients with GERD symptoms.

RESUMEN

Ante mortem cases of venous thrombosis in patients with nonbacterial thrombotic endocarditis (NBTE) have not yet been reported. We describe a rare case of NBTE in a patient with mesenteric vein thrombosis. A healthy 37-year-old man with abdominal pain and fever underwent emergency small bowel resection due to bowel ischemia resulting from mesenteric vein thrombosis. Transthoracic echocardiography revealed multiple mobile masses attached to the anterior leaflet of the mitral valves and their chordae tendineae. On suspicion of infective endocarditis, the cardiac masses were excised through open-heart surgery. However, pathologic reviews were compatible with NBTE. The patient was stable after the cardiac surgery and was treated with warfarin. Laboratory and imaging findings regarding his hypercoagulable condition were all negative.
