Obesity is non-infectious pandemic. Its association with cardiovascular pathology is especially widely discussed, but an overweight patient is actually polymorbid. An increase of body mass provides a pathogenetic basis for many diseases including those of digestive system This review deals with pathogenesis, clinical features, and treatment of gastroesophageal reflux disease, cholelithiasis and non-alcoholic fatty liver disease in obese patients. This pathology and its aggravation result from such pathophysiological processes as a rise in intra-abdominal pressure, excess adipokine, cholesterol and free fatty acid synthesis, activation of lipid peroxidation. Gastroesophageal reflux disease in obese patients has an atypical clinical course characterized by discrepancy between clinical, endoscopic and morphological features in oesophagus and frequent formation of Barrett's oesophagus. Cholelethiasis in obesity is fraught with further progress of the disease after prescription of low-fat diet. The risk of calculi formation can be reduced by prescription of ursodeoxycholic acid that produces both litholytic and hypolipidemic effects. Treatment of non-alcoholic fatty liver disease requires combined therapy with statins, insulin sensitizers, hepatoprotectors and adequate physical activity. Sustained remission of diseases of digestive organs is impossible without correction of body mass and their pharmacotherapy requires increasing doses of medicines and duration of their administration.

The aim of the study was to determine the clinical significance of intestinal functional and structural alterations in biliary pathology. Clinical, endoscopic, morphological, and morphometric methods were used. The subjects of the study were 62 patients with functional gall bladder disorder, 90 patients with chronic calculous cholecystitis, and 90 patients who had undergone cholecystectomy for cholelithiasis. The study found that biliary lithogenesis was associated with intestinal dysbiosis, changes in the qualitative density of erythrocytes immunopositive to motilin and substance P, and inflammatory changes in the intestines. After cholecystectomy, changes in intestinal microecology progressed, inflammatory and atrophic changes in the intestinal mucosa appeared or deepened, the qualitative density of erythrocytes immunopositive to motilin and substance P decreased, and colon polyps appeared more frequently.

The subjects of the study were 164 patients, divided into two groups. Group I included 76 patients at the physicochemical stage of cholelithiasis, and 38 patients after cholecystectomy, who underwent endoscopic papillosphincterotomy (EPST). Group II (control) included 30 patients at the physicochemical stage of cholelithiasis, and 20 patients after cholecystectomy, who did not undergo EPST. Endoscopic retrograde pancreatocholangiography revealed type II Oddi's sphincter dysfunction in all the patients. Evaluation of the chemical composition of bile in Group I, performed 6, 12, 18, and 24 months after EPST, revealed its graduate stabilization. In Group II the dynamics of bile composition was negative--in 8 patients bile became more lithogenic. Long-term observations showed that 6 years after EPST bile was lithogenic only in 4 Group I patients, while at the same moment in 25 Group I patients bile lithogenicity did not disappear, but even worsened. Biliferous tract ultrasonography, performed long after EPST, found biliary sludge in 4 Group I patients. 6-year observation of Group Il patients, including ultrasonography, demonstrated that during the 4th year of observation biliary sludge occurred in as many as 28 patients, in 15 of whom small concrements on the bottom of the gall bladder were found during the 5-6th year of observation, and in 3 of whom a solitary concrement of 4 to 5 mm in diameter was found in the choledoch. The results demonstrate that it is appropriate to perform EPST as early as at the physicochemical stage of cholelithiasis, because this procedure results in stabilization of biliary colloid balance and thus prevents biliary sludge and forming of gall bladder concrements. At the same time, 36% of patients with cholelithiasis at various stages who did not undergo EPST, formed gall bladder concrements. EPST is also appropriate in some patients after cholecystectomy, in order to prevent repeating gall bladder concrement formation.

Disturbed motility of the upper gastrointestinal tract presenting with phasic derangement (the absence of all motor phases or peristaltic duodenal contraction, abnormal duration of phases) has been found out in all cholelithiasis patients examined. The findings should in no way be viewed as isolated chronic duodenal insufficiency. Impairment of esophageal, gastric and duodenal motility needs identification and correction in combined treatment, rehabilitation and prevention of cholelithiasis.
