Improvement of the algorithm for diagnostics of postcholecystectomy syndrome taking into account functional and organic changes in the area of the large duodenal nipple

Abstract

The aim. Improving the algorithm for diagnosing patients with postcholecystectomy syndrome (PCS), taking into account functional and organic changes in the major duodenal papilla (MDP).
 Materials and methods. 208 patients with PCS were examined. Laparoscopic cholecystectomy (CE) was performed in 172 patients in history, open CE was performed in 36 patients. 47 patients had obstructive jaundice, 84 had signs of biliary hypertension without an increase in bilirubin, 77 had no signs of biliary hypertension and an increase in bilirubin.
 The following instrumental research methods were used: abdominal organs ultrasound examination (AO USE), duodenoscopy, endoscopic retrograde cholangiopancreatography (ERCP), computed tomography (CT). In the main group, to study the morphofunctional changes in MDP, duodenoscopy with parietal impedancemetry, ultrasound of the hepatobiliary zone with a choleretic load were used.
 Results. In the main group, 34 patients underwent ultrasound of the hepatobiliary zone and Vater's nipple area with a choleretic breakfast according to Boyden according to the method of Grigoriev P.Ya. in our modification, 21 patients had an expansion of the choledochus by 2 mm. At the same time, taking meverin led to a decrease in the diameter of the choledochus, which indicated functional changes in the MDP. In 13 patients, the expansion of the choledochus, observed when taking a choleretic breakfast, persisted with the use of antispasmodics, which indicated the presence of an organic pathology of MDP. Duodenoscopy with impedancemetry was performed in 41 patients: 20 patients had 760–820 Ohm, which indicated the presence of functional changes, 12 patients had inflammatory changes in the MDP and 703–760 Ohm were detected, 9 patients with cicatricial fibrous changes had indicators impedance measurement 640–703 Ohm. The use of ultrasound with a choleretic breakfast and duodenoscopy with parietal impedancemetry in patients of the main group made it possible to identify functional and organic (inflammatory, fibrous) changes in the MDP, which made it possible to develop a therapeutic algorithm using both conservative therapy and the use of various options for transpapillary endoscopic interventions.
 Conclusions. Conducting an in-depth diagnosis of morpho-functional changes in MDP using parietal impedancemetry of MDP and ultrasound of the hepatobiliary zone with choleretic load allows us to identify both functional and morphological changes in MDP, which makes it possible to develop a therapeutic algorithm using drug therapy and transpapillary endoscopic techniques.
