| Normal Histology of the Large Intestine |

Non-neoplastic
Colorectal diseases:
Complicated diverticular disease |
|
Note:
Specimen dissection
and block selection depends on the specific pathology. Blocks:
Sections are taken at
each 10cm distance from the proximal to distal resection margins. |
|
Handling and preservation of freshly received specimen in the lab: - The pathologist should examine the serosal surface of the unopened fresh specimen (look for fistula or perforation) - Specimen is opened throughout its length along the antimesenteric wall (including any stricture). - Faeces blood and mucus removed by gentle washing in cold running water. - Resection specimen pinned to cork board and fixed for atleast 48 hrs. - Specimen may be unpinned and floated free in fixative after initial 24 hrs. Gross description of the specimen:
Description should include the nature of
specimen (extent of surgical resection).
Record the following features:
-Serosa - fibrin, pus,
fibrosis, adherence of mesentery Visit: Gross examination of polypectomey specimens
