In the past few years there have been increasing needs for and interest in creation of valves to delay transit of small bowel content into the colon following resection of small bowel and disruption of the normal physiologic mechanisms for control of motor function of the small bowel and colon. The increasing need stems from numerous immediately successful massive small bowel resections. It is also recognized that loss of the ileocecal valve mechanism aggravates deficiencies resulting from bowel resection. Several methods have been suggested. A few patients have had interposition of short reversed segments of jejunum1-7 and there have been numerous evaluations of such procedures in animals.5,8-13 More recently Schiller et al reported on the removal of segments of longitudinal muscle layer of small bowel, thereby interrupting peristalsis and creating short areas of functional or anatomic stenosis.14 Other procedures include recirculating loops,2-15 gastric tubes11 and
