Manometría endoscópica del esfínter de Oddi / Endoscopic manometry of sphincter of Oddi

RESUMEN

Background: Endoscopic manometry is the gold standard for the diagnosis of sphincter of Oddi dysfunction. Aim: To report the result of the first 30 endoscopic manometries of sphincter of Oddi performed in a Gastroenterology Service. Patients and methods: Thirty manometries were performed in 28 patients aged 30 to 70 years old (14 females). The papilla was cannulated with a perfused catherter, measuring pressure with external transducers. Results: Deep cannulation of the papilla was achieved in 88 por ciento. Procedure-related complications were not observed in these cases. Normal values were registered in 11 cases with a basal sphincter pressure 15.6ñ10.7 mm Hg, contractions with an amplitude of 92.3ñ35.7 mm Hg and 6.0ñ2.4/ min frequency. The clinical suspicion suspicion of hypertonic dyskinesis was confirmed in 5 cases with an elevated basal pressure of 43.69ñ13.3 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 aphincter function. Conclusions: Endoscopic manometry is a reasonably safe method, of great importance in the diagnosis of fuctional disorders of the sphincter of Oddi
