Abstract
Purpose:
A mathematic model was developed to quantify colonic reservoir pouch capacity and to allow comparison with capacity of the parent colonic segment from which the pouch was fashioned.
Methods:
Using geometry, pouch capacity was calculated and various capacities were enumerated.
Results:
From this model, ideal pouch dimensions can be predicted, which are 6 to 7 cm of undistended bowel circumference with limb lengths of 8 to 10 cm.
Conclusions:
Such a pouch maximizes the pouch colon capacity ratio and has a calculated undistended capacity between 60 and 105 ml.
