Periappendicular changes in patients with ulcerative collitis: overview and clinical observation

Ulcerative colitis is inflammatory bowel disease which characterized by inflammation of the colon and rectum: only 20-30% of UC patients have pancolitis, while proctitis and left-sided colon lesions are more common. There is a variant of localization of ulcerative colitis in patients with proctitis and left-sided colon lesion, which changes the rule of continuity of the lesion and is described as an additional periappendicular lesion. The article have been presented the own clinical observation of a patient with distal ulcerative colitis with periappendicular lesion. If a periappendicular lesion have been detected during endoscopy in a typical clinic for distal ulcerative colitis and doubts arise about the correctness of the previously established diagnosis, it is necessary to re-analyze the anamnesis, symptoms, instrumental and histological picture and, taking into account new knowledge about the course of ulcerative colitis in some patients with periappendicular lesion, confirm the initial diagnosis and continue therapy. Such a finding, according to the available literature data, does not require escalation of ulcerative colitis therapy and, as a rule, does not mean the spread of the disease to all parts of the colon.
