[Medical nutrition after cholecystectomy]

Cholecystectomy (CE) is one of the most frequently performed surgical interventions and the main method of symptomatic gallstone disease treatment. Despite the widespread implementation of minimally invasive surgery techniques, significant proportion of patients develop spectrum of symptoms after CE. These manifestations require correction with different approaches including medical nutrition. The aim of the research was to perform structured review of recently published data related to diet therapy and nutritional support of patients after CE. Material and methods. A literature search was performed in PubMed/MEDLINE, EMBASE, Cyberleninka, eLibrary databases using the keywords "Cholecystectomy" in combination with "Diet", "Medical nutrition", "Nutritional support" and their Russianlanguage equivalents for the relevant databases. Correct description of interventions, analyzed outcomes, statistical processing and found effects where necessary for the inclusion to the analysis. Duplicate publications were excluded. Results and discussion. A review of the recommendations on nutritional support after CE has been conducted, including handbooks and clinical guidelines, results of relevant clinical trials evaluating the efficacy of different measures of nutritional support. The rational of traditionally used dietary approaches for the correction of symptoms that develop after CE has been assessed, as well as recently published data on the effectiveness of nutritional support methods. Conclusion. Disturbed regulation of bile secretion in the early CE postoperative period may support the need for limitation of fat consumption. Impaired circulation of bile acids and possible changes in the balance of intestinal microbiota may support the need for the use of prebiotics (like dietary fiber), as well as probiotics, especially when antibiotic treatment was administrated for the patient. These interventions may be important from the viewpoint of prevention of late complications after CE.
