Background: Gastric polyps encompass a wide variety of lesions that most commonly arise from the gastric epithelium. However, coincidental gastric carcinomas have rarely been reported, being found in $1.5{\sim}2.1%$ of patients with hyperplastic polyps. The sizes and the pathologies of polyps seem to be important in the application of treatment. Therefore, it is necessary to classily gastric polypoid lesions after a gastrectomy. Materials and Methods: During a follow-up endoscopy study, 23 patients were found to have developed gastric polyps after a gastrectomy. Most of those polyps were removed by using an endoscopic polypectomy. We performed clinical and pathologic evaluations of the gastric polyps in the remainding in the stomach after a gastrectomy, Results: The mean age of the patients was 64.5 years old with the incidence of polyps remainding in the stomach after a gastrectomy increasing after the first year following the gastrectomy. The sizes of the polyps ranged from 0.3cm to 3.5cm in diameter and the numbers of polyps below 1.0cm were 19 (82.6%). The anastomotic site was the most prevalent place 10 (43.2%), followed by the cardia 6 (26.0%) and the body 4 (17.3%). Among 23 gastric polypoid lesions Yamada types of gastric polyps in the remainding in the stomach were as follows: 1 case in type I, 12 cases in type II, 9 cases in type III, 1 case in type IV. The pathologic diagnoses of the polyps were hyperplastic polyps in 6 cases, tubular adenomas in 2 cases and inflammatory polyps in 15 cases. Conclusion: Endoscopic polypectomy is believed to be important in assessing the precise diagnosis of gastric polyps remainding in the stomach. In this study, hyperplastic polyps were found to have no malignant potential, despite their sizes. As a result aggressive biopsy with a polypectomy of gastric polyp afier gastrectomy is recommended and frequent follow-up be performed.

Background: This study aimed to evaluate upper gastrointestinal polyps detected during esophago-gastroduodenoscopy tests. Materials and Methods: We conducted a retrospective analysis on data regarding 55,987 upper gastrointestinal endoscopy tests performed at the endoscopy unit of Istanbul Education and Research Hospital between January 2006 and June 2012. Results: A total of 66 upper gastrointestinal polyps from 59 patients were analyzed. The most common clinical symptom was dyspepsia, observed in 41 cases (69.5%). The localizations of the polyps were as follows: 29 in the antrum (43.9%), 15 in the corpus (22.7%), 11 in the cardia (16.7%), 3 in the fundus (4.54%), 3 in the second portion of the duodenum (4.54%), 2 in the bulbus (3.03%) and 3 in the lower end of the esophagus (4.54%). Histopathological types of polyps included hyperplastic polyps (44) (66.7%), faveolar hyperplasia (8) (12.1%), fundic gland polyps (4) (6.06%), squamous cell polyps (4) (6.06%), hamartomatous polyps (3) (4.54%), and pyloric gland adenoma (3) (4.54%). Histopathological analysis of the gastric mucosa showed chronic atrophic gastritis in 30 cases (50.84%), HP infection in 33 cases (55.9%) and intestinal metaplasia in 19 cases (32.20%). In 3 cases with multiple polyps, adenocarcinoma was detected in hyperplastic polyps. Conclusions: Among polypoid lesions of the upper gastrointestinal tract, the most common histological type is hyperplastic polyps. Generally, HP infection is associated with chronic atrophic gastritis and intestinal metaplasia. The incidence of adenocarcinoma tends to be higher in patients with multiple hyperplastic polyps.
