Notes: Abstract One hundred forty elderly cancer outpatients with colostomy in the authors' rehabilitation department were included in an analysis of the feasibility, effectiveness, and safety of periodic irrigation of remaining colon with lukewarm tap water with the aim of regaining full continence. Sixteen patients did not have a sufficiently long remaining bowel (cecostomy, transverse colostomy) and 17 were considered unsuitable to learn the technique because of advanced neoplastic disease with poor life expectancy, intercurrent disease, or stomal problems. One hundred seven patients were proposed to perform the irrigation: 17 refused to do so with the remaining 90 able to learn the method without problems. Nearly all patients achieved full continence for at least 24 hours. Three patients refused to continue, and nine interrupted for minor complications. The median duration of irrigation in the whole group is 257 days (range, 1 to 2669 days): 32 patients have been irrigating from one to five years, and 9 patients for more than 5 years. Based on these results, we recommend irrigation as standard rehabilitative treatment for elderly patients.

Notes: This paper presents a generalization of a computational method for the prediction of solute dispersion in fractured porous media. This method is specially useful for the prediction of subsurface flows in crystalline rocks. The model now includes a linear kinetics mechanism to represent the effects of sorption of radionuclides in the rock matrix. The method is improved in its accuracy and provides results useful for the assessment of radionuclide migration in high-level, radioactive waste repositories. Results including verification (analytical) and physical test simulations are given. These results provide a partial validation of the numerical model.
