[What is the value of anorectal manometry today?].

Since it was first introduced into clinical investigations in 1960 by M. Schuster, anorectal electromanometry has become one of the most-important methods to evaluate anorectal continence. Electromanometry now is a wide-spread, safe and simple screening method to analyze chronic constipation and to control the results of proctologic surgery. Its most important parameters are the anorectal pressure profile, the squeezing pressure profile, the adaptation reaction, the internal sphincter relaxation, and the rectal sphincteric reflex to the external anal sphincter. Wherever proctology is performed, electromanometry and electromyography of the external sphincter muscle should be done.

Epiphrenic diverticulum with abnormal manometry: a case report.

A 50-year-old man was admitted to our hospital with the chief complaints of vomiting and nocturnal cough for one year. His complaints were progressive and had worsened within the last two months. Chest X-ray revealed a right-sided paracardiac opacity. Computed tomography of the thorax showed a supradiaphragmatic mass lesion containing air and solid components. Barium esophagogram revealed a giant distal esophageal diverticulum and hiatal hernia. Stationary manometric examination of the esophagus showed non-specific esophageal motility disorder. The patient underwent a successful abdominal approach diverticulectomy operation and the postoperative course was uncomplicated. There is a high prevalence of esophageal motility abnormalities in patients with epiphrenic diverticula, though they are very rare, and, as in this case, may be difficult to classify.

[Effect of drugs on endoscopic manometry of the sphincter of Oddi].

We used a catheter passing through the papilla duodeni under the view of endoscope, with persistent perfusion system and transducer, to measure the pressure and contraction frequency of sphincter of Oddi (SO) in 10 healthy persons and 20 patients. Meanwhile, we compared the effect of Buscopan, Nitrostat and Vitamin K3 on the pressure and contraction frequency (CF). SO basal pressure (BP) in healthy group was 5.21 +/- 1.61 kPa (mean +/- s), SO peak pressure (PP) 8.21 +/- 1.34 kPa and CF 6.14 waves/min. In the group of peripapillary fistula, SO pressure decreased significantly and CF slowed down greatly. In comparison with the healthy group, SO pressure and CF in the group of gallbladder stone, choledocholithiasis and pancreatic diseases did not show any change of statistic significance. Intravenous injection of Buscopan could decrease SO peak pressure and BP remarkably. Sublingual administration of Nitrostat and intramuscular injection of Vit K3 could reduce SO PP markedly, SO BP didn't change statistically. It was also showed that spheric and semi-spheric papillae had higher pressure than the flat ones (P less than 0.001).

[Limitations of the traditional manometric test and advantages of computerized manometry in the study of esophageal motility].

The analysis of esophageal motility tracings is laborious, time consuming and subject to reader variability. The motility traces of five patients were analyzed separately by five experienced readers, in order to assess the inter and intra observer variability. Later on, the manual analysis of the motility traces of five healthy volunteers and four patients was compared to the automatic analysis performed by a computerized system. The inter- and intra-observer variability (expressed as coefficient of variation) was high in the manual analysis, especially for the abdominal length of the lower sphincter and the duration of the esophageal body contractions (coefficient of variation ranging from 18 to 43%). On the contrary, automatic readings proved almost identical to the means obtained by manual analysis (Pearson factor 0.988 for amplitude and 0.89 for the duration of contractions). Moreover, the computerized automatic analysis gave a significant time gain in respect to manual readings and eliminated the inter and intra-observer variability.

[Esophageal manometry and pH-monitoring: cost-benefit analysis].

Functional tests of the esophagus have become increasingly popular over the last 10 years. Here we present a cost/benefit analysis model to evaluate the real contribution to diagnosis with reference to the cost of these tests. All of the patients referred to the digestive physiopathology laboratory at the Institute of Surgical Semiotics, from 1988 to 1990, were evaluated for gastroesophageal reflux disease (152 cases), dysphagia (27 cases) and chest pain (12 cases). The cost of each modified diagnosis was L. 508,250 in the first case, L. 315,772 in the second case and L. 262,446 in the third case. Additionally, concerning gastroesophageal reflux disease, the cost of medical therapy based on endoscopic diagnosis alone was compared to that of medical therapy guided by these functional tests. Hence it was demonstrated that it is economically advantageous to study functionally all of the symptomatic patients, except the cases of esophagitis, and patients with atypical symptoms or with mild symptoms and endoscopic esophagitis of the first degree. It is not worthwhile investigating patients with second, third or fourth degree esophagitis, regardless of the symptoms, and patients with typical severe symptoms and first degree esophagitis. These functional tests are economically practical in all cases in which morphologic alterations are either absent or minimal.

[Surgical treatment of gastroesophageal reflux. Evaluated by manometry and 24-hour pH monitoring of the esophagus].

From 1980 to 1989, 46 patients underwent surgery for pathological gastro-oesophageal reflux disease; 28 with Nissen technique, nine with Hill technique and nine with a modified Belsey technique. 11 patients (24%) experienced postoperative complications, 21% after Nissen, 33% after Hill and 22% after Belsey. Two of six patients suffered recurrence of their reflux symptoms after Belsey, three of six after Hill and two of 26 (8%) after Nissen. 85% experienced no reflux symptoms after Nissen fundoplication. 17 patients suffered from flatulence, three were not able to belch and two were not able to vomit. Median lower oesophageal sphincter pressure before Nissen fundoplication was 6.0 mmHg and length was 2.0 cm. After the operation the pressure increased to 10.0 mmHg and the length to 3.0 cm. Four patients underwent ambulatory 24-h oesophageal pH monitoring both preoperatively and postoperatively. The preoperative registration was pathological in all patients, but in three patients the postoperative pH was normal.
