[DIFFERENTIAL MANAGEMENT AT THE SPHINCTER OF ODDI DYSFUNCTION AFTER CHOLECYSTECTOMY].

Aim: Develop a differential management at the patients with suspected sphincter of Oddi dysfunction after cholecystectomy.

Materials and methods: 169 patients after cholecystectomy, divided into 2 groups. 1st group - 60 patients after repeated surgery formed as a comparison group. They multivariate analysis of clinical, laboratory and ultrasonic data revealed the most significant signs of organic causes of cholestasis, expressed in scores. 2nd group - 109 patients with a suspected sphincter of Oddi dysfunction, who did not have symptoms of organic pathology. Types of bile outflow were assessed by hepatobiliary scintigraphy (GBSG). In cases of doubtful diagnoses computer tomography, magnetic resonance cholangiopancreatography, and/or retrograde cholangiopancreatography are performed.

Results: According to the scoring system, patients 1st group scored 4 or more (8,7 ± 3,87) points. GBSG performed only in 7 (11.6%) patients, and in all cases the cholestatic type of bile outflow was detected. The amount of estimated points in the 2nd group was 2-3 points (2,43 ± 0,34; p < 0.05). GBSG performed in all patients and three types of bile outflow were revealed: normal - in 21 (19.2%) patients, cholestatic in 8 (7.3%), and accelerated - in 80 (73.3%) patients. When refining the diagnosis in 10 (9%) patients had hidden organic disorders of bile outflow, served as an indication for surgery.

Conclusion: Scoring system for the assessment of the suspected sphincter of Oddi dysfunction allows to differentiate of patients for invasive research and surgery. In our study group of 109 patients received less than 4 points, they have dominated the functional disorders, but the results of a detailed examination, 9% of patients had latent organic changes that have become indications for surgical treatment.
