Does colonoscopy cause increased ulcerative colitis symptoms?

BACKGROUND: Ulcerative colitis (UC) patients often report symptom flares after colonoscopy. However, this has not been documented in the literature. OBJECTIVES: 1. Determine whether colonoscopy is associated with increased UC symptoms. 2. Determine whether there is a need for escalation of UC medications after colonoscopy. 3. Identify baseline variables associated with increased symptoms after colonoscopy. METHODS: Fifty-five outpatients with a history of UC, intact colon, and quiescent disease were enrolled in a prospective case-crossover study. Subjects were evaluated with the Simple Clinical Colitis Activity Index (SCCAI) before colonoscopy, 1 week and 4 weeks after colonoscopy. A mixed model analysis was used to accommodate nonindependence of repeated measurements on the same patients. RESULTS: Fifty-one (91%) subjects completed the study. Six subjects had clinical relapse defined by a score of 5 or greater on the SCCAI during the week after colonoscopy. Five subjects increased their 5-aminosalicylic acid (5-ASA) medications immediately postcolonoscopy, two of whom had a SCCAI 5 or greater. Multivariate modeling demonstrated a clear association between the week immediately after colonoscopy preparation and increased disease activity, with the time period being predictive of increased SCCAI (week 1 vs. week 4, P = 0.0127). The baseline SCCAI (P value < 0.0001) and prednisone use (P = 0.0120) were predictive of increased SCCAI postcolonoscopy. Thiopurines (P < 0.001) were protective against increased symptoms. CONCLUSIONS: In our study, 1 in 8 subjects had UC relapse by SCCAI immediately postcolonoscopy, and 1 in 10 subjects required an increase in their 5-ASA medications. Clinicians should be cognizant of this effect of colonoscopy in patients with UC.

Women patients' preference for women physicians is a barrier to colon cancer screening.

BACKGROUND: The preference of women patients for women physicians has been shown in many specialties. Women patients awaiting a lower endoscopy have been shown to have a preference for women endoscopists. The reasons for this preference and the strength of this preference have not been studied in the primary care setting. METHODS: A questionnaire was given to female patients who were waiting for primary care appointments at 4 offices. Patients reported sociodemographic characteristics, experiences with colorectal cancer (CRC), barriers to CRC screening, gender preference of their physician, the significance, and reasons for this preference. RESULTS: A total of 202 women patients aged 40 to 70 years (mean 53 years) completed the questionnaire. Of these patients, 43% preferred a woman endoscopist, and of these, 87% would be willing to wait >30 days for a woman endoscopist, and 14% would be willing to pay more for one. The most common reason (in 75%) for this gender preference was embarrassment. Univariate analysis revealed that gender of the primary care physician (PCP), younger patient age, current employment, and no previous history of colonoscopy were predictors of preference for a woman endoscopist. Of these variables, only female gender of the PCP (OR 2.84: 95% CI[1.49, 5.40]) and employment (OR 2.4: 95% CI[1.23, 4.67]) were positive predictors for a woman endoscopist preference by multivariable analysis; 5% stated that they would not undergo a colonoscopy unless guaranteed a woman endoscopist. The sole independent factor associated with adherence to screening was PCP recommendation (OR 2.93: 95% CI[1.63, 5.39]). CONCLUSIONS: Women patients frequently prefer a woman endoscopist, and this preference is reported as being strong enough to delay the procedure and to incur personal expense. It is an absolute barrier to endoscopy according to 5% in this subset of women surveyed. Interventions must be made in the primary care setting to address this issue and to increase the participation of women patients in CRC screening.
