Gastric and duodenal polyps in familial polyposis
Endoscopy with multiple biopsies of the upper gastrointestinal tract was repeated yearly over a two to six year period in nine patients with familial polyposis coli from three families. Adenomatous polyps, one to 20 in number and 2-8 mm in size, were detected in the antrum and the first and second duodenal portions in seven patients, while hyperplastic polyps were detected in four patients in t...

Gastric polyps are frequently encountered on endoscopic examinations. While many of these represent true epithelial lesions, some of the polyps may result from underlying stromal or lymphoid proliferations or even heterotopic tissue.

The patient underwent a radical subtotal gastrectomy with Billroth I anastomosis. Pathology revealed adenocarcinomas wi...
متن کاملEvidence for an hMSH3 defect in familial hamartomatous polyps.
BACKGROUND Patients with hamartomatous polyposis syndromes have increased risk for colorectal cancer (CRC). Although progression of polyps to carcinoma is observed, pathogenic mechanisms remain unknown. The authors examined whether familial hamartomatous polyps harbor defects in DNA mismatch repair (MMR), and assayed for somatic mutation of PTEN, a gene inactivated in the germline of some hamar...

The other mode of treating these patients are subtotal colectomy with ileorectal anastomosis alongwith regular follow up with proctoscopy for development of cancer in retained rectal mucosa(3,7). Recently, Stevan et al. (8) utilized laproscope for total proctocolectomy as well as ileoanal anostomosis while others performed ileopouch anal anastomosis alongwith total proctocolectomy(9,10).
