Abstract

Developed for the study of dialysis in the continent jejunal reservoir (CJR), a novel, uncomplicated approach to achieve continence in construction of a small-bowel reservoir is presented. We utilize a technique of constructing a continent nipple valve, which entails the reduction or tapering of the intussusceptum prior to invagination into the reservoir. We have thus far performed the procedure successfully in 21 dogs. All animals have achieved absolute continence. Complications have occurred in two animals, neither complication involving the nipple valve. Pressure-volume cytometry in nine animals demonstrates continence in the awake animal at pressures of up to 40 cmH2O (volumes being limited by animal discomfort due to reservoir distention). In postmortem studies, reservoir capacities of > 1000 ml and pressures of > 70 cmH2O have been attained without loss of continence or prolapse of the nipple valve. Continence is sustained even when the reservoir and nipple valve are subjected to high intraluminal pressures. Incorporating a tapered intussusceptum, the continent reservoir provides absolute continence without the use of cumbersome mesh fixation or lithotropic intraluminal staples.
