Analysis of serum gastric function and Helicobacter pylori infection in patients with gastric hyperplastic polyps and gastric fundic gland polyps / 中国综合临床

Objective To analyze the serum gastric function and Helicobacter pylori ( HP ) infection in patients with gastric hyperplastic polyps and gastric fundic gland polyps.Methods From December 2017 to December 2018, 135 patients with gastric polyps and pathologically confirmed gastric hyperplastic polyps and gastric fundic gland polyps were enrolled in the hospital of Xuzhou Medical University.Among them, 68 patients with hyperplastic polyps, 67 cases of the gastric fundic gland polyps.Serum Hp antibodies ( UreA, UreB, VacA, CagA antibodies ) were qualitatively detected by immunoblotting.Eighty patients with chronic superficial gastritis were selected as the control group.Three groups of serum pepsinogen?I ( PG?I),pepsinogen?Ⅱ( PG?Ⅱ),gastrin were detected by enzyme?linked immunosorbent assay (ELISA).Gastrin?17( G?17) and calculate PGⅠ and PGⅡ ratio( PGR).Results The levels of serum PGⅡ(13.13(8.15,20.30) μg ／L) and G17 (8.44(3.72,27.17) pmol／L) in the gastric hyperplastic polyp group were higher than those in the control group (9.16(5.56,15.14) μg／L and 1.83(0.87,5.95) pmol／L) ( P＜0.05),and the PGR level was lower than the control group ( P＜0.05);serum PGI ( 120.12 ( 86.72,174.70) μg／L), PGII ( 11.92 ( 7.27,22.26) μg／L),G17 ( 5.68 ( 1.79, 14.65) pmol／L) in the gastric fundic gland polyp group was higher than the control group (( 101.32 (79.17,131.33) μg ／L,9.16 ( 5.56,15.14) μg ／L,1.83 ( 0.87,5.95) pmol／L) ( P 均＜0.05)) ( P＜0.05); serum G17 (8.44(3.72,27.17) pmol／L) level in gastric hyperplastic polyp group was higher than gastric fundus polyp group (5.68(1.79,14.65) pmol／L) ( P＜0.05); Hp infection rate in gastric hyperplastic polyp group61.76%(42／68)was higher than that in the gastric fundic gland polyp group40.30%(27／67) (P＜0.05),and type I Hp was the main one (P＜0.05).The serum PGⅡ and G17 levels in the gastric hyperplastic polyp group were higher than those of Hp negative ( all P＜0.05).There were no significant differences in serum PGI, PGⅡ, G17, and PGR levels between the HP?positive and negative?positive patients in the gastric fundus polyp group.The serum PGI and PGR levels in the hypertrophic polyp group were higher than those in the HPⅡ type ( all P＜0.05).There was no significant difference in the levels of serum PGⅠ,PGⅡ,G17,and PGR between the gastric fundic gland polyps group and the type Ⅱ.Conclusion Serum PG and G17 levels in patients with gastric hypertrophic polyps and gastric fundic gland polyps are higher than those in patients with chronic superficial gastritis.Patients with gastric hyperplastic polyps have higher HP infection rate and abnormal gastric function than gastric fundic gland polyps.

A Rare Case of Lymph Node Metastasis from Early Gastric Cancer

Gastric cancers that fulfill the Japanese criteria for curative endoscopic resection show a low risk of lymph node (LN) metastasis. Here, we report a case of LN metastasis from early gastric cancer that fulfilled the curative criteria. A 74-year-old Japanese woman was referred to our hospital for treatment of early gastric cancer identified at the site of a hyperplastic polyp that had been diagnosed 10 years prior to presentation. Contrast-enhanced computed tomography did not show any lymphadenopathy and laparoscopy-assisted distal gastrectomy was performed. Histopathological examination revealed a predominantly moderately differentiated adenocarcinoma that measured 15 mm in size and was confined to the mucosa. However, a single metastatic regional LN was observed. A few cancer cells showed positive staining for alpha-fetoprotein. It should be noted that early gastric cancer can be accompanied by LN metastasis even if it fulfills the criteria for curative endoscopic resection.

Adenocarcinoma Occurring in a Gastric Hyperplastic Polyp Treated with Endoscopic Submucosal Dissection

Gastric hyperplastic polyps are generally considered benign lesions, although rare cases of adenocarcinoma have been reported. Although, the underlying mechanism of carcinogenesis in gastric hyperplastic polyps is still uncertain, most malignant polyps are seen to originate from dysplastic epithelium rather than from hyperplastic epithelium. Herein, we report the case of a woman diagnosed with adenocarcinoma that originated from a hyperplastic gastric polyp that was successfully removed by endoscopic submucosal dissection. In this case, we observed adenomatous changes around the cancerous component.

The clinical significance on typing of hyperplastic gastric pits / 中国基层医药

Objective To explore the clinical significance of gastric hyperplastic polyp pits under magnifying endoscopy. Methods Summary confirmed by magnifying endoscopy and pathological examination gastric hyperplastic po]yp's performance of magnifying endoscopy,Hp positive and the results of pathology during February 2004 to De-cember 2006. Results 55 patients found 116 gastric polyp,41.4% (48/116) with type A,26.7% (31/116) with type B,19. 8% (23/116) with type C,8. 6% (10/116) with type D,2. 6% (3/116) with type E,one case gastric pits blurred(type F) 0. 9% (1/116). 4 cases with type E and type F found moderate-severe atypical hyperplasia. Conclu-sion Gastric hyperplastic polyp pits with type E and type F ,their results of pathology to display atypical hyperplasia.

Two Cases of Adenocarcinoma Arising from Gastric Hyperplastic Polyp / 대한소화기내시경학회지

Epithelial gastric polyps can be categorized as being either hyperplastic or adenomatous. Hyperplastic polyps accounts for 75~90% of gastric polyps. In contrast to the adenomatous polyps, the potential of a malignant transformation of hyperplastic polyps was originally believed to be quite low (an incidence of 1.5~2.1%), which is considerably lower than that of an adenoma of the stomach. Most of reported cases of a hyperplastic gastric polyp with a transformation to adenocarcinoma were well differentiated histopathologically. There are few reports of a hyperplastic polyp in which malignant changes developed during the endoscopic surveillance. We report a rare case of a 1.2 cm sized moderately differentiated adenocarcinoma arising in a hyperplastic polyp on the cardia in the stomach with a brief review of the relevant literature.
