[Differential diagnosis of ulcerative colitis].

Important points during differential diagnosis of ulcerative colitis from other inflammatory disorders are endoscopic examination and microbial studies of stools. In acute phase of enterocolitis in which waterly diarrhea with bloody stool and abdominal pain appeared, infectious enterocolitis by Shigella, Salmonella, Campylobacter and Yersinia, which sometimes causes mucosal edema, hyperemia, erosions and ulceration should be distinguished carefully. Microbial studies of stool would bring helpful information in such situation. In chronic phase of inflammatory diseases of bowel, they often showed chronic diarrhea associated with mucobloody stools and abdominal pain. They often revealed mucosal inflammation mimicking ulcerative colitis during endoscopic evaluation. Among them, most important diseases are amebic colitis, ischemic colitis, radiation colitis and antibiotics associated hemorrhagic colitis.

Crohn's-like complications in patients with ulcerative colitis after total proctocolectomy and ileal pouch-anal anastomosis.

Total proctocolectomy with ileal pouch-anal anastomosis (IPAA) has become an established surgical procedure for ulcerative colitis. Occasional patients who have undergone IPAA develop persistent or recurrent episodes of pouchitis (chronic pouchitis), from which a subset also develop gastrointestinal and systemic complications that are identical to those seen in Crohn's disease. These complications include enteric stenoses or fistulas in the pouch or pouch inlet segment, perianal fistulas or abscesses, pouch fistulas, arthritis, iridocyclitis, and pyoderma gangrenosum. The development of Crohn's-like gastrointestinal complications in a patient with chronic pouchitis frequently engenders concern that the pathologist misinterpreted the proctocolectomy specimen as ulcerative colitis instead of Crohn's disease. We describe eight patients who developed chronic pouchitis and Crohn's-like complications after IPAA and total proctocolectomy. In each case, concern was voiced about misinterpretation of the proctocolectomy specimen as ulcerative colitis instead of Crohn's disease after the development of the Crohn's-like complications. Preoperatively, all eight patients had characteristic clinical, radiographic, and pathologic features of ulcerative colitis. Review of the pathology specimens indicated that all eight had ulcerative colitis. Crohn's-like complications are most likely related to chronic pouchitis, which probably is a form of recrudescent ulcerative colitis within the novel environment of the pouch. A diagnosis of Crohn's disease after IPAA surgery should only be made when reexamination of the original proctocolectomy specimen shows typical pathologic features of Crohn's disease, Crohn's disease arises in parts of the gastrointestinal tract distant from the pouch, pouch biopsies contain active enteritis with granulomas, or excised pouches show the characteristic features of Crohn's disease, including granulomas. There were no histologic differences in the total colectomy specimens between the eight ulcerative colitis study patients and 16 control ulcerative colitis patients who had a favorable clinical outcome after IPAA surgery groups. Crohn's-like complications and chronic pouchitis does not necessarily imply an incorrect original interpretation of ulcerative colitis by the pathologist.

Cytoplasmic antineutrophil cytoplasmic antibody-positive vasculitis associated with ulcerative colitis.

The case of a man with poorly controlled ulcerative colitis, who developed a cytoplasmic antineutrophil cytoplasmic antibody-positive systemic vasculitis, causing small bowel infarction is reported. Antineutrophil cytoplasmic antibodies occur in 50-70% of patients with ulcerative colitis, but are usually of the perinuclear or atypical pattern; the cytoplasmic pattern seen in this case is indicative of systemic vasculitis. A variety of vasculitic diseases have been reported as occurring rarely with ulcerative colitis, but this report is the first description of a cytoplasmic antineutrophil cytoplasmic antibody-positive vasculitis with this association.

[Granulomatous rosacea associated with ulcerative colitis: 2 case reports].

Inflammatory gastrointestinal disorders (ulcerative colitis and Crohn's disease) are often associated with cutaneous disorders, which occasionally may even precede the internal symptoms. Aside from the specific skin diseases, such as erythema nodosum or pyoderma gangraenosum, a number of unspecific skin eruptions may be found in both disorders. Here we report on 2 cases of ulcerative colitis associated with granulomatous rosacea.

Colonic mucosal hemodynamics and tissue oxygenation in patients with ulcerative colitis: investigation by organ reflectance spectrophotometry.

Colonic mucosal hemodynamics were investigated at the rectosigmoidal region of the colon in 46 patients with ulcerative colitis and in 18 normal subjects by organ reflectance spectrophotometry under colonoscopy. The value for the index of mucosal hemoglobin concentration (IHb) was significantly higher, and value for the index of mucosal hemoglobin oxygen saturation (ISO2) was significantly lower in patients with active ulcerative colitis than values in the normal controls or in patients with inactive ulcerative colitis. The results indicate mucosal congestion and hypoxemia in patients with active ulcerative colitis. The changes in IHb and ISO2 correlated well with the severity of ulcerative colitis scored by endoscopic findings and with the number of infiltrating inflammatory cells in the mucosa analyzed histologically in biopsy samples. In conclusion, the colonic mucosal microcirculation in patients with active ulcerative colitis was disturbed and showed congestion and hypoxemia. The analysis of hemodynamic changes may be helpful for assessing the activity of ulcerative colitis.

Chronic ulcerative colitis. Traditional surgical techniques.

The patient with ulcerative colitis requiring surgery has several options from which to choose. Although the pelvic pouch procedure may be preferred by many patients, in fact, all of the operations have both their advantages and disadvantages. Thus, patients should be fully informed of the various options and participate in the surgical decision making. Surgeons performing elective operations on patients with ulcerative colitis should be experienced with all of the procedures. Only then can they be unbiased in presenting the various options to the patient. Advocates of total proctocolectomy often cite the high complication rates of the Kock and pelvic pouch procedures and condemn these operations on this basis. However, the magnitude of a total proctocolectomy cannot be minimized, and the complication rate of this procedure is significant. On the other hand, total proctocolectomy is often condemned because of the permanent ileostomy and the perceived poor quality of life. This appears to be untrue. Most patients, regardless of which operation is performed, have a high quality of life. This is likely a result of the fact that physical well-being is excellent in most patients, and this may be the primary determinant of quality of life in these patients. It must be accepted, however, that some patients do have difficulties psychologically or physically with an ileostomy. Fortunately, there are several alternatives available for these people.
