- (2)having an abdominal infection with tuberculosis or atypical mycobacteria at the time of clinical worsening of mesenteric panniculitis;
- (3)for mesenteric panniculitis of the colon only, having undergone colonoscopy within the 48 hours before the clinical worsening of mesenteric panniculitis;
- (4)inability to obtain appropriate clinical management for mesenteric panniculitis;
