مرکز منطقه ای اطلاع رساني علوم و فناوري - Frequency of various types of gastric polyp

Abstract :

Aim. Any discrete lesion protruding into the lumen of gastrointestinal tract detected by endoscopy is called as “polypoid lesion”. Thus, we aimed to study the demographic, clinical, and endoscopic characteristics of patients with gastric polypoid lesions. Method. Upper gastrointestinal system endoscopy was carried out in a total of 3375 patients between the dates of October 2006-July 2010. In 66 (1.95%) of these patients polypoid lesions were observed in various anatomical sites of the stomach, and polypectomy was performed. Sixty six patients who had gastric polyp or polpys were included in this study. The localization, size, histopathological findings and treatment of the polyps were recorded. All patients had at least one gastric polyp confirmed by histological examination. Results. The most frequent presenting symptom was epigastric pain (72.7%) followed by dyspepsia (18%), and anemia (4.5%). Fifty-one of the patients had one, 8 had two and 7 had three polyps. Out of 88 gastric polypoid lesions, 41 (46.5%) were located in the antrum followed by 26 (29.5%) in corpus, 12 (13.6%) in cardia, and 9 (10.4%) in around anastomoses. Fifty-three (60.2%) of the polyps were smaller than 1 cm, 23 (26.1%) were between 1-2 cm, and 12 (13.7%) were larger than 2 cm. In the histopathological examination of the polyps, 71 (80.7%) were found to be hyperplastic polyps, 15 (17%) were inflammatory polyps and 2 (2.3%) were adenomatous polyps. All patients with multiple polyps had only a single histological type. Conclusion. For this reason, endoscopic polypectomy to be a sensible diagnostic and therapeutic procedure of gastric polyps when feasible. Finally, endoscopic surveillance in these patients may be recommended to exclude both possibility of recurrence and cancer development elsewhere in stomach.
