To determine whether physiological differences exist between primary (swallow-induced) and secondary (distension-induced) peristalsis in humans, 10 healthy male volunteers underwent esophageal manometry on 2 consecutive days using a perfused intraluminal catheter system that incorporated a latex balloon. Initially the catheter was positioned so that the balloon was centered 16 cm above the lower esophageal sphincter (LES), and intraluminal pressures were recorded 21, 11, 6, and 1 cm above the LES. After a series of wet swallows, dry swallows, and balloon distensions, the catheter was repositioned so that the balloon was 6 cm above the LES and pressures were recorded 1 and 11 cm above the LES. A series of balloon distensions were repeated in this position, and the subject was then given either atropine (10 micrograms/kg iv) or placebo in a double-blind randomized fashion (on consecutive days). The protocol was then repeated in reverse order. Distension-induced responses aboral to the balloon with the balloon located 16 cm above the LES were 1) of lower amplitude, 2) more often nonperistaltic, and 3) less atropine sensitive than swallow-induced contractions at comparable sites. With the balloon located distally (6 cm above LES) contractions induced at the 11-cm site (i.e., orad to the balloon) were much more atropine sensitive than contractions induced at the same site when the balloon was located proximally (i.e., 16 cm above LES). These data suggest that, contrary to previous reports, secondary peristalsis differs significantly from primary peristalsis. Furthermore, atropine differentially effects these two types of peristalsis, suggesting that the neural pathways involved are dissimilar.

This study aimed to determine the interactions between closely paired swallow-induced primary peristalsis (PP) and air injection-induced secondary peristalsis (SP). Ten subjects (7 men, 18–42 yr) were studied using a catheter, including two sleeves (upper and lower esophageal sphincters), a midesophageal infusion port, and seven esophageal and two pharyngeal recording sites. Ten iterations of PP and SP were induced by 5-ml water swallows and 20-ml intraesophageal air injections, respectively. Thereafter, the interactions between PP and SP, separated by 1- to 12-s intervals, were studied in all four possible sequences: paired swallows, swallow preceded by air injection, air injection preceded by swallow, and paired air injections. Tracings were analyzed for lower esophageal sphincter relaxation, presence and integrity of peristalsis, and event interaction. Eight subjects with success rates of both ≥90% PP and ≥80% SP were analyzed (PP 97 ± 2%, SP 90 ± 3%). During paired PP interactions and SP followed by PP, the first sequence was inhibited by the second with intervals < 4–6 s. However, no inhibition of the first peristaltic sequence was found in either PP followed by SP trials or SP followed by air injection. In contrast to swallowing or proximal esophageal distention, air injection into the lumen of the midesophagus does not inhibit an ongoing peristaltic event. Being that the elicitation of SP in the smooth muscle esophagus is intramurally mediated, this suggests that deglutitive inhibition is a centrally mediated phenomenon rather than an intrinsic property of peristalsis.
