Numerous epidemiological, animal and experimental studies support a positive association between chronic Helicobacter pylori(H. pylori) infection and the development of gastric cancer. However, the exact mechanism whereby H. pylori causes gastric carcinogenesis remains unclear. It has been demonstrated that expression of cyclooxygenase-2(COX-2) is elevated in gastric carcinomas and in their precursor lesions. In this review, we present the latest clinical and experimental evidence showing the role of gastrin and COX-2 in H. pylori-infected patients and their possible association with gastric cancer risk.展开更多

Occasionally,patients with this condition are diagnosed with malignant tumors. We report a case of a 60-yearold woman with gastric cancer and SIT. Laparoscopyassisted distal gastrectomy(LADG) with D2 lymph node dissection and Billroth Ⅱ anastomosis were performed successfully on the patient by careful consideration of the mirror-image anatomy. The operation required 230 min, and no intraoperative complications occurred. The final pathological report was p T4 a N0M0,according to the American Joint Committee on Cancer 7th edition staging guidelines. The postoperative course was favorable, and the patient was discharged on postoperative day 8. We believe that this is the first case of LADG with D2 lymphadenectomy reported in a SIT patient with advanced gastric cancer.展开更多

The pattern of reflux is different in LPR and gastroesophageal reflux. LPR usually occurs during the daytime in the upright position whereas gastroesophageal reflux disease more often occurs in the supine position at night-time or during sleep. Ambulatory 24-h double pH-probe monitoring is the gold standard diagnostic tool for LPR. Acid suppression with proton pump inhibitor on a long-term basis is the mainstay of treatment. Helicobacter pylori(H. pylori) is found in many sites including laryngeal mucosa and interarytenoid region. In this paper, we aim to present the relationship between LPR and H. pylori and review the current literature.展开更多
