[Endoscopic manometry of Oddi's sphincter].
BACKGROUND
Endoscopic manometry is the gold standard for the diagnosis of sphincter of Oddi dysfunction.


OBJECTIVE
To report the results of the first 30 endoscopic manometries of sphincter of Oddi performed in a Gastroenterology Service.


METHODS
Thirty manometries were performed in 28 patients aged 30 to 70 years old (14 females). The papilla was cannulated with a perfused catheter, measuring pressure with external transducers.


RESULTS
Deep cannulation of the papilla was achieved in 88%. Procedure-related complications were not observed in these cases. Normal values were registered in 11 cases with a basal sphincter pressure 15.6 +/- 10.7 mm Hg, contractions with an amplitude of 92.3 +/- 35.7 mm Hg and 6.0 +/- 2.4/min frequency. The clinical suspicion of hypertonic dyskinesis was confirmed in 5 cases with an elevated basal pressure of 43.69 +/- 13.3 mm Hg, an increased frequency of contractions ("tachyoddia") in one, and large spastic contractions of high pressure in other case. In 3 of 5 cases with common bile duct stones, a predominance of retrograde propagation of the contractions was observed with normal pressure. Variable manometric results were observed after endoscopic papillotomy observing a scale from the complete absence of motor activity to normal sphincter function.


CONCLUSIONS
Endoscopic manometry is a reasonably safe method, of great importance in the diagnosis of functional disorders of the sphincter of Oddi.
