Addition of methyl cellulose enema to double-contrast barium imaging of sigmoid diverticulosis.

UNLABELLED: Double-contrast barium enema has a reduced sensitivity in patients with severe sigmoid diverticulosis. Therefore a carboxy methyl cellulose enema was employed after the conventional double-contrast examination in 15 patients with sigmoid diverticulosis. A significant increase in lumen diameter and a superior removal of barium residue from the diverticula facilitated the interpretation of the sigmoid loops. CONCLUSION: The addition of methyl cellulose enema to double-contrast barium imaging improves diagnostic imaging in diverticulosis by expanding the lumen and emptying the diverticula.

Risk of relapse in new cases of ulcerative colitis and indeterminate colitis.

PURPOSE: Changes in morbidity pattern of ulcerative colitis have created a need to update understanding of the course of the disease. METHOD: A follow-up study was done of relapse rates and progression of inflammation in 571 non-selected patients with ulcerative and indeterminate colitis. RESULTS: Relapse rate ten years after diagnosis was 70 percent in definite ulcerative colitis, 22 percent in probable ulcerative colitis, and 77 percent in indeterminate colitis. During the study period, there was no change in the relapse rate. In relapsing proctitis, 52 percent developed more extensive inflammation. Fifty-four percent of patients with only one attack of colitis had persistent signs of inflammatory bowel disease. CONCLUSIONS: Shift in morbidity pattern to a greater proportion of patients with proctitis at diagnosis and a shorter time from onset of symptoms to diagnosis had no influence on the relapse rate. Indeterminate colitis has a worse prognosis than definite ulcerative colitis. Considering the documented efficacy of sulfasalazine, the high relapse rate calls for studies of the effectiveness of such treatment in everyday practice.

Operations in unselected patients with ulcerative colitis and indeterminate colitis. A long-term follow-up study.

OBJECTIVE: To assess the need for operative treatment for ulcerative colitis and indeterminate colitis. DESIGN: Retrospective study. SETTING: University Hospital, Sweden. SUBJECT: All patients diagnosed from 1958 to 1982, in Malmö, Sweden-ulcerative colitis (n = 471) and indeterminate colitis (n = 100). MAIN OUTCOME MEASURES: Incidence of colectomy. RESULTS: The mean follow-up was 15 years. The incidence of colectomy was 7.51, 1.90 and 36.13/1000 person years for definite ulcerative colitis, probable ulcerative colitis and indeterminate colitis, respectively. The incidence of colectomy in patients with definite ulcerative colitis in the present study was low compared with other studies. In contrast to other reports, men had a threefold risk while extent of inflammation did not influence the incidence. Patients with indeterminate colitis were a high risk group with a high incidence of colectomy. The high incidence among patients with indeterminate colitis compared with that in patients with definite ulcerative colitis was also seen in subgroups such as patients with total colitis at diagnosis, in patients in remission after the first attack, and in patients with a severe attack. CONCLUSION: As patients with indeterminate colitis seem to be at increased risk of colectomy it could be important to distinguish them from those with ulcerative colitis. Today, however, it is not possible to identify all patients with indeterminate colitis early in the course of the disease.

Incidence of colorectal cancer and all cause mortality in non-selected patients with ulcerative colitis and indeterminate colitis in Malmö, Sweden.

Cancer morbidity and all cause mortality were studied prospectively in all patients with definite and probable ulcerative colitis and indeterminate colitis diagnosed from 1958 to 1982, in the city of Malmö, Sweden. The follow-up to Jan. 1, 1990 was complete for all but ten patients. Nine of the 471 patients with ulcerative colitis and three of the 100 patients with indeterminate colitis developed colo-rectal cancer. The incidence of colorectal cancer in ulcerative colitis was 1.4 per 1000 person-years. The observed number of cases was 2.1 times higher than expected; (95% C.I. 1.0-4.1), based on the age- and sex-specific cancer incidence in the city during the study period. Indeterminate colitis was associated with a higher colorectal cancer risk than ulcerative colitis; 2.4 per 1000 person-years; (SMR 8.6, 95% C.I. 1.8-25.1). Both conditions were associated with a slight increased mortality rate, for ulcerative colitis 12.6 per 1000 person-years; (SMR 1.3, 95% C.I. 1.0-1.5), and for indeterminate colitis 11.7 per 1000 person-years; (SMR 2.7, 95% C.I. 1.6-4.4). Complications of colitis were the main cause of death in both groups. The cancer risk was related to extent of disease, duration of disease and female gender. Ten out of the 12 cases with cancer had or developed total colitis. However, only seven of the 134 cases with total ulcerative colitis and two of 87 cases with total indeterminate colitis developed cancer.(ABSTRACT TRUNCATED AT 250 WORDS)

Ulcerative colitis and indeterminate colitis in the city of Malmö, Sweden. A 25-year incidence study.

BACKGROUND: This study was designed to assess time trends in the incidence of ulcerative colitis and indeterminate colitis in an urban population. METHODS: Medical records of in- and out-patients with inflammatory bowel disease were reviewed by a panel to establish the diagnosis. All histopathologic specimens and almost all radiographs were re-examined. RESULTS: During the time period 1958 to 1982 there were 354 new cases of definite ulcerative colitis, 117 of probable ulcerative colitis, and 100 of indeterminate colitis. This corresponds to an average annual incidence per 100,000 of 5.5, 1.8, and 1.6, respectively. The incidence was higher in men than in women. Peak incidence was between 20 and 29 years, but indeterminate colitis was most common in 10- to 19-year-old males. The incidence was stable from 1958 to 1972 but then increased in almost all age groups in both sexes. The increase in annual incidence of definite ulcerative colitis from 4.2 to 9.4/10(5) corresponds to an average annual increase of about 5% (p < 0.001). The increase in the incidence of definite ulcerative colitis was due to an increased proportion of patients with proctitis. CONCLUSIONS: This study has shown an increased incidence of ulcerative colitis and indeterminate colitis, and we have found no reason to believe that this is a spurious finding.

Determining normal bolus size for thin liquids.

In order to define a suitable volume of barium to be delivered to patients during the radiographic evaluation of pharyngoesophageal function during swallowing, three different age groups of nondysphagic volunteers were studied. Subjects randomly swallowed boluses of water, barium, and Coca-Cola. The size of a normal thin liquid bolus was 21 ml (SD +/- 5 ml). We intend to include this information to compare different bolus sizes in cineradiographic examination of patients with swallowing complaints.
