The authors studied the motility of transverse colon used for reconstruction of the pharyngogastric transit after esophagectomy. The study included 10 patients who underwent esophagectomy 15 to 201 months (median, 48.5 months) before motility evaluation. Nine patients underwent operation because of caustic injury and one, because of esophageal cancer. The age of the patients ranged from 19 to 54 years (median, 36 years). A manometric esophageal catheter with five side holes spaced 5 cm apart (using the continuous perfusion method) was used to record motility. In three patients, it was not possible to introduce the manometric catheter inside the colon interposition. In the other seven, most of the time there was no contraction when motility was recorded. In four, there was contraction only in the segment 2 to 5 cm below the upper esophageal sphincter. In three, there were peristaltic or simultaneous contractions of long duration, sometimes associated with dry or wet swallows. The motility of colon interposition used to restore transit after esophagectomy is similar to that described for the colon. The contractions may be the consequence of graft distention after successive swallows.
