Aims:

Patients undergoing stomach or colon carcinomas may have polypoid lesions in the anastomosis on follow-up endoscopy and colonoscopy. Pathology results of biopsies taken from these lesions were evaluated retrospectively.

Methods:

A total of 34 patients were included in the study. Ten of the patients had previously undergone surgery due to stomach cancer. Of the patients, 24 had already underwent operation due to colon cancer. Biopsies were taken from the polypoid lesions detected in the anastomosis on follow-up endoscopy and colonoscopy of the patients. Biopsies were evaluated by pathology. In suspicious cases advanced immunohistochemical staining was done in the biopsy samples.

Results:

Polyps detected in gastric anastomosis; 5 were reported as hyperplastic polyps (50%), 3 as inflammatory polyps (30%), and 2 as adenocarcinoma (20%). Colonic anastomotic polyps were reported; 10 as inflammatory polyps (41.6%), 9 as hyperplastic polyps (37.5%), 3 as adenocarcinoma (12.5%) and 2 as tubuler adenomas (8.3%).

Conclusions:

In this study, 20% of gastric anastomotic polyps and 12.5% of colonic anastomotic polyps were found to be malignant. Polypoid lesions detected in anastomosis should be evaluated pathologically even if their appearance is benign.
