| Diverticular disease | |
|---|---|
| Diagnosis in short | |
 Diverticulum. H&E stain. | |
|
| |
| LM | mucosa/submucosa invaginate into the musuclaris propria |
| Site | colon - classically sigmoid, other sites |
|
| |
| Associated Dx | diverticulitis, peritonitis, diverticular disease-associated colitis |
| Symptoms | usu. asymptomatic, diverticulitis presents with abdominal pain |
| Clin. DDx | colorectal carcinoma |
Diverticular disease, also diverticulosis, is a common disease of the colon. Inflammation of diverticula is known as diverticulitis.
General
- Very common.
- Typically seen in elderly patients - 50s and 60s.
Complications:
- Diverticulitis.
- Peformation - peritonitis.
- Diverticular-associated colitis - see below.
Diverticular disease-associated colitis
Features:[1]
- Rare.
- Definitions vary somewhat - one is: IBD-like inflammation restricted to areas with diverticular disease.
- Considerable overlap with IBD histologically - no definite histologic findings.
- Rectal biopsy may be used to differentiate from ulcerative colitis.
Gross
- Corrugated - like cardboard.
- Wall thickening (reactive).[2]

Grossing notes
Microscopic
Features:
- Mucosa/submucosa invagination into the musuclaris propria (MP).
- At the site the blood vessels supplying the mucosa and submucosa penetrate the MP.[3]
DDx:
- Colorectal carcinoma - may cause a stricture, usually obvious on microscopy.
- Inflammatory bowel disease.

SIGMOID COLON, SIGMOIDECTOMY: - DIVERTICULAR DISEASE WITHOUT DIVERTICULITIS. - NEGATIVE FOR MALIGNANCY.
Perforated
RECTO-SIGMOID, LARGE BOWEL RESECTION: - PERFORATED DIVERTICULITIS WITH SEROSITIS AND ABSCESS FORMATION. - SUBMUCOSAL FIBROSIS. - ONE LYMPH NODE NEGATIVE FOR MALIGNANCY ( 0 POSITIVE / 1 ). - NEGATIVE FOR MALIGNANCY.
SIGMOID COLON, RESECTION: - PERFORATED COLON ASSOCIATED WITH FAT NECROSIS, SEROSITIS AND MICROABSCESS FORMATION, IN THE SETTING OF DIVERTICULAR DISEASE. - ONE LYMPH NODE NEGATIVE FOR MALIGNANCY ( 0 POSITIVE / 1 ). - NEGATIVE FOR DYSPLASIA AND NEGATIVE FOR MALIGNANCY.
