    Clinical and manometric findings in benign peptic strictures of the esophagus (1979)
    Springer
    Digestive diseases and sciences 24 (1979), S. 858-861

    Notes: Abstract To determine the possible factors that may contribute to the development of peptic stricture of the esophagus, clinical and manometric features were compared in patients with symptomatic gastroesophageal reflux and those with peptic strictures of the esophagus. Patients with stricture were older and had a longer duration of heartburn than patients without a stricture. Most importantly, patients with stricture had a more marked decrease in lower esophageal sphincter (LES) pressure, 4.9±0.5 mm Hg, than patients without a stricture, 7.5±0.6 mm Hg, P〈0.01. The LES pressure in all patients with stricture was below 8 mm Hg, and did not overlap with normal values. Patients with stricture had either a nonspecific motor abnormality or aperistalsis (64%), compared to patients with symptomatic reflux (32%), P〈0.05. Thus, peptic stricture of the esophagus is commonly associated with a long duration of reflux symptoms in patients with a very low LES pressure and esophageal motor disorder.

    Esophageal peristaltic force in man (1977)
    Springer
    Digestive diseases and sciences 22 (1977), S. 589-597

    Topics: Medicine
    Notes: Abstract The purposes of this study were: (1) to quantify human esophageal peristaltic force, (2) to determine the factors which alter this force, and (3) to evaluate the relationship between force and intraluminal pressure. Force was measured in normals by using a mercury-in-Silastic strain gauge. Simultaneous pressures were obtained through constantly infused open-tipped catheters. On separate days a sphere of either 6.0-, 9.0-, or 13.0-mm diameter was attached to the strain gauge and measurements were obtained at three esophageal levels. Studies were done (1) with the subject at rest, (2) while performing a Valsalva maneuver, (3) during the administration of bethanechol, and (4) after intravenous atropine. Peristaltic force increased directly with sphere size but inversely with distance from the lower esophageal sphincter. Intraluminal pressure did not change significantly with sphere size or at different levels of the esophagus. A Valsalva maneuver increased force and pressure significantly only in the distal esophagus. Bethanechol (0.1 mg/kg) had no significant effect on force at any esophageal level, but atropine (0.01 mg/kg) decreased force at each esophageal level and with each sphere size. The distal esophageal response to a Valsalva maneuver was lost following atropine. Intraluminal pressure was a good index of peristaltic force, providing sphere size and esophageal level remained unaltered. These studies suggest that esophageal peristaltic force may be altered by: (1) bolus size, (2) extrinsic maneuvers which alter intraluminal pressure (Valsalva maneuver), and (3) certain pharmacological agents.

    Human colonic myoelectric activity in response to prostigmin and the gastrointestinal hormones (1977)
    Springer
    Digestive diseases and sciences 22 (1977), S. 881-887

    Notes: Abstract Colonic myoelectric activity was determined using a mucosal clip electrode in normal human subjects, in the basal state and following the administration of prostigmin, pentagastrin, cholecystokinin, or secretin. Slow-wave activity was present 49±3.0% of the recording time and occurred at two frequencies, 6.5±0.1 cycles/min and 3.5±0.1 cycles/min, in the rectum. Spike potentials were infrequent in the basal state. Prostigmin, pentagastrin, or cholecystokinin did not affect the slow-wave activity or frequency, but these agents significantly increased the number of spike potentials (P〈0.05). Secretin had no effect on myoelectric activity. The electrode system was tested in the cat and showed excellent correlation of the myoelectric activity between the mucosal clip electrode and a serosal electrode. These studies indicate: (1) a mucosal clip electrode provides an accurate method of recording colonic myoelectric activity when compared to a serosal electrode in the cat; (2) in man, slow-wave activity is present only intermittently and exists at two frequencies, approximately 6 cycles/min and 3 cycles/min; (3) gastrointestinal hormones and prostigmin increase spike potential discharge without altering slow-wave activity or frequency.
