Study population: All of the ambulatory colonoscopies performed at our Hospital

Brief summary: This study was designed to: estimate the incidence of cat scratch colon in the investigators environment; explore the diseases associated to its development; identify the factors related to its development; and assess its clinical repercussions.

Detailed description: All of the ambulatory colonoscopies performed at the investigators University Hospital from September 2007 were prospectively included in the study. Data recorded for each patient included: age, sex, disease background, reason for the examination, hematological data and the endoscopic diagnosis.

Every patient presenting CSC lesions had colon biopsies taken. These were studied by a single anatomic pathologist specializing in gastrointestinal pathologies.

The characteristics (age, sex, disease background, indication for surgery, age at the time of surgery, time elapsed since surgery, hematological data and pathoanatomical study of the colon biopsies) of diversion colitis patients with and without CSC lesions will bi compared.

Eligibility criteria: Inclusion Criteria:

* All of the ambulatory colonoscopies performed at our University Hospita

Exclusion Criteria:

* Patients thats refused.
