Intraluminal pH esophageal motility.

The aim of the present study was to investigate the effect of intraluminal pH on motor activity of the lower esophageal body. Liquid boluses of different pH values (7 to 2) were infused in the esophagus of 14 normal subjects during manometric recording of motor activity. Each test infusion elicited an esophageal motor response, either secondary peristalsis or simultaneous contractions. Secondary peristalsis was elicited by similar volumes of perfusates at pH 7, 6, 5, but significantly less volumes were needed with perfusates pH 4, 3, and 2. Simultaneous motor activity was not affected by intraesophageal pH value in the range investigated.

Functional evaluation of colon transplants used in esophageal reconstruction.

Studies were performed on the mechanical activity of iso- and antiperistaltic colon segments used to replace the esophagus. Transplants were challenged with a semiliquid bolus and/or a 0.1 N HCl solution, considered as common stimuli for an in situ esophagus, and the mechanical activity was investigated by means of synchronized manometric and cinefluorographic recordings. Basal activity of the interposed colon was limited to occasional monophasic waves of the segmenting type; the acid solution and the semiliquid bolus constantly elicited a peristaltic motor response transporting the contents to the gastric fundus or, in antiperistaltic colon, from the distal to the proximal part.

Blood pH: a test for assessment of severity in proctocolitis.

Acid base balance was studied in 58 patients with active idiopathic proctocolitis; the condition of 10 of them was complicated by toxic megacolon. Arterial blood pH increased progressively with increased severity of the colitis and as the lesions became more widespread. Statistically significant differences were observed in pH values between the mild/moderate and severe forms and between the severe and complicated forms ('toxic megacolon'). A linear correlation was found between pH and the amount of intestinal gas, pulse rate, and plasma albumin.
