[Radiotelemetric manometry of the urinary bladder].

The standard procedure for manometric investigation of bladder function involves the use of a urethral catheter. The presence of this foreign body causes irritations, however, with a resultant increase in urethral resistance. This perturbs the micturition process, but it can be avoided by a new telemetric method of intravesical pressure measurements. A very small pressure gauge and radio emitter are introduced into the bladder, and the values measured are transmitted to an external receiver. Thus, for the first time, is possible to perform physiological studies of bladder function that do not require catheterization or special positioning of the patient and are well tolerated. Some examples are described, which show that this method allows repeated catheter-free investigations over longer periods of time and accurate evaluation of the effects of pharmacological products on bladder function.

[Anorectal manometry and ileo-anal anastomosis: pre- and postoperative manometric comparison].

The aim of this study was to evaluate the physiological and manometric changes of anorectal function after proctocolectomy and ileal J pouch anastomosis performed in 13 patients. A short muscular rectal cuff was conserved in the first 5 patients, mucosectomy was performed in the next patients (Group M), and the entire rectum and proximal portion of the anal canal (1 mm above the dentate line) were resected without mucosectomy (Group WM) in the most recent patients. With a median postoperative follow-up of 18 months, anorectal continence was perfect in 9 patients, and minimal incontinence were observed in 4 patients (2 patients in Group M, and 2 patients in Group SM). In Group M, the resting lower anal canal pressure was significantly decreased after the operation and was less than the postoperative resting lower anal canal pressure observed in Group SM. The resting upper anal canal pressure in continent patients was inferior to the postoperative values measured in patients with minimal incontinence. In all the groups, no change in squeeze pressure was observed after the operation. During the postoperative period, the rectoanal inhibitory reflex was absence in all patients. The volume necessary for sensation threshold was increased after the operation, in the same number of patients in Group M and SM, and more frequently in continent patients compared with patients with soiling. The absence of muscular rectal cuff and mucosectomy seems to provide best results than rectal cuff preservation. After the operation, a marked decrease in the resting pressure and an increase in the volume necessary to onset of threshold sensation, were associated with the presence of minimal incontinence.

[Gallbladder dyskinesia and manometry of Oddi's sphincter].

Sphincter of Oddi activity partly regulates bile flow into the small intestine. This regulation is mainly controlled by phasic contractions and basal tone of the sphincter, together with gallbladder contraction. Manometric studies of the sphincter have permitted a better understanding of its physiological role and implication in biliary dyskinesia symptoms. Motility abnormalities of Oddi's sphincter present classically as bouts of recurrent pain and/or idiopathic pancreatitis, that can be successfully cured by endoscopic sphincterotomy.

Esophageal manometry in children with esophagitis.

Esophageal motility was studied in 31 patients with mild to moderate esophagitis and in 48 patients without esophagitis to determine the effect of esophageal inflammation on lower esophageal sphincter pressure, and the amplitude, duration, and velocity of esophageal contractions. There were no significant differences in any of these parameters associated with esophageal inflammation. We conclude that mild to moderate esophagitis does not cause serious esophageal dysfunction in children.

[Anorectal manometry in children with chronic functional constipation and encopresis].

We performed a rectal motility study in 39 children with encopresis and in 41 with chronic functional constipation. A three balloon system Schuster technic, was employed. Pressure changes were recorded. The "Inflation" reflex was absent in 23/39 children with Encopresis 59% and in 11/41. 26.8% with chronic functional constipation (p < 0.05).
