Abstract
Motor activity of the colon transplant for esophageal reconstruction is a point of controversy. Manometric studies carried out in 15 patients subjected to isoperistaltic colon interposition are presented. Manometric studies were carried out with 2 polyvinyl water-filled catheters inserted through pressure transducers. Basal colonic activity and motor activity following several stimuli and dry swallows were registered. The type of waves after stimuli was classified as: synchronous, sequential (or progressive) and segmental. Details of the basal colonic waves and colon contractions after stimuli are given: i.e., rate, duration, amplitude, interval from the stimulus and percentage of motor activity. Good motor response of the isoperistaltic colon to intraluminal injection of water or 0.1 N HCl and to cachet swallowing was indicated. Only 2 symptom-free patients did not have motor activity. One of them was submitted to manometric studies too soon after the operation. The presence of sequential waves in the interposed segment can likely help propel the contents of the colon into the stomach and clear gastric juice if reflux from the stomach should occur.
