Contents
Fixation
Generally 10% neutral buffered formalin. Causes include volvulus and arterial occlusion.
Comprehensiveness
On this resource, the following formatting is used for comprehensiveness:
- Minimal depth
- (Moderate depth)
- ((Comprehensive))
Gross examination
- Measure specimen length
- Measure smallest and largest diameter
- Describe serosa (color, adhesions) and mesentery
- If a volvulus is still twisted, describe the twist and measure its distances from the resection margins
- Open the bowel. Most will be filled with air, others filled with feces
- Describe the mucosa - color, presence or absence of mucosal folds
- Measure the thickness of the bowel wall
- Sections submitted for microscopy:
- Resection margins
- Transition between normal and abnormal
- Any mesenteric abnormality or enlarged lymph node
Gross report
Example:
| ( Countainer is labeled: ____ ). The specimen (is received in formalin and) consists of of bowel measuring __ cm in length(, __ cm in diameter) and __ cm in thickness. The bowel grossly appears edematous. (Representative sections are submitted for microscopic examination in __ cassettes.) |
Further information: Colon
Microscopic examination
The main signs of colon ischemia are:[1]
- Thrombosis, which are often hyaline, in small vessels
- Necrosis, ulceration and granulation tissue, extending into submucosa and surrounding smooth muscle fibers of muscularis mucosa
- Hemorrhage and edema in lamina propria
