A toxic megacolon is a rare but life-threatening complication, especially in ulcerative colitis , which rapidly ( fulminant ) leads to acute enlargement ( dilation ) of the large intestine (→ megacolon ) and is characterized by inflammation and a septic - toxic state. The Chagas disease , Crohn's disease or pseudomembranous colitis can lead to toxic megacolon.
Symptoms
Symptoms are, besides a painfully distended acute abdomen :
- Ileus
- shock
- high fever ( septic temperature )
- greatly increased sedimentation rate
- Tachycardia
- anemia
- Disturbances in the water-electrolyte balance
Diagnosis
The diagnosis is carried out by x-rays (→ empty abdomen image).
therapy
The toxic megacolon is difficult to control conservatively , so that therapy is usually performed surgically. The aim is to relieve the intestine, primarily by creating an ileostomy . Alternatively, surgical fistulization of the transverse colon with the sigmoid is possible . Radical surgery (→ proctocolectomy with ileoanal pouch anastomosis ) is the method of choice, especially for ulcerative colitis .
histology
Due to the autoreactive response of the immigrated granulocytes, the mucosa and submucosa show multiple ulcers. This mainly results in connective tissue necrosis, which can lead to dilation and perforation of the colon.
