Enteral nutrition improves health-related quality of life in Crohn's disease patients with long disease duration.

BACKGROUND/AIMS: Although enteral nutrition therapy has been highlighted as maintenance therapy for Crohn's disease, few reports have investigated the impact of enteral nutrition on the health-related quality of life of Crohn's disease patients. METHODOLOGY: We cross-sectionally evaluated the effect of multiple clinical factors including enteral nutrition on the health-related quality of life of Crohn's disease patients focusing on patient disease duration using the Inflammatory Bowel Disease Questionnaire. RESULTS: Of all 126 patients examined, 95 patients were receiving enteral nutrition. Multiple linear regression analysis using 18 clinical parameters revealed that disease activity was a dominant factor that affected the health-related quality of life of Crohn's disease patients, and that enteral nutrition was also an independent factor that improved the Inflammatory Bowel Disease Questionnaire total score, bowel symptoms, and systemic symptoms for patients with a disease duration of 10 years or more (P = 0.0090, 0.0033, and 0.016, respectively). CONCLUSIONS: Enteral nutrition improved the health-related quality of life of Crohn's disease patients with long-term disease duration. Thus, enteral nutrition should be recommended as one of the options for maintenance therapy for Crohn's disease.

Clinical factors that impair health-related quality of life in ulcerative colitis patients vary with the disease duration.

BACKGROUND AND AIM: The health-related quality of life (HRQOL) of patients with ulcerative colitis (UC) can be impaired because of the chronic symptoms. Although UC patients suffer from such symptoms over the long term, there have been few reports on the changes of HRQOL with disease duration. The aim of this study was to clarify these changes. METHODS: The HRQOL of 331 Japanese UC patients was examined using the validated Japanese version of the Inflammatory Bowel Disease Questionnaire (J-IBDQ). HRQOL and factors affecting HRQOL identified using multiple linear regression analysis were stratified by disease duration. RESULTS: Of the 15 clinical factors examined, the clinical activity index score was the strongest determinant (P<0.0001) of all the scores of IBDQ regardless of disease duration. HRQOL did not differ significantly among patients with different disease durations. The factors, however, that affected HRQOL varied according to disease duration. In patients with disease duration of less than 5 years, the clinical activity index score was the predominant factor affecting HRQOL. Being 'on sick leave or hospitalized' was a significant factor impairing HRQOL in patients with disease duration of 5-9 years. Moreover, complications due to corticosteroids significantly impaired all of the IBDQ scores in patients with disease duration of 10 years or more. CONCLUSION: Factors that affected the HRQOL of UC patients varied according to the patients' disease duration. Our findings should assist in the development of a long-term strategy for the treatment of UC patients.

Endoscopic papillary balloon dilation and endoscopic sphincterotomy for bile duct stones: long-term outcomes in a prospective randomized controlled trial.

BACKGROUND: Little is known about the long-term outcome of endoscopic papillary balloon dilation for removal of bile duct stones. A randomized trial that compared long-term outcomes after endoscopic papillary balloon dilation and endoscopic sphincterotomy was conducted. METHODS: Thirty-two patients with bile duct stones were randomized to endoscopic papillary balloon dilation or endoscopic sphincterotomy, with 16 patients in each group. Endoscopic papillary balloon dilation was performed by using an 8-mm-diameter balloon; endoscopic sphincterotomy was performed in the standard manner. The success rates for stone removal, as well as the frequency and types of early (<15 days), mid-term (<1 year), and long-term (1-6 years) post-procedure complications were evaluated. RESULTS: The success rates for stone removal and early complication rates were similar for both groups. The frequency of stone recurrence was approximately 4-fold higher in the endoscopic papillary balloon dilation group (25%) vs. the endoscopic sphincterotomy group (6.3%) at mid-term evaluation. However, over the long term, Kaplan-Meier estimated probability of stone recurrence tended to be higher in the endoscopic sphincterotomy group vs. the endoscopic papillary balloon dilation group; recurrent stones were found in, respectively, 26.7% vs. 6.3%. Complications occurred in 7 patients in each group. CONCLUSIONS: Long-term outcome of endoscopic papillary balloon dilation for bile duct stone removal is satisfactory, provided that consideration is given to recurrence of stones by early follow-up evaluation.
