Cholecystokinin Metabolic Profile in Post-bariatric Patients

Abstract

To describe the metabolic effect of cholecystokinin and its relationship with post-bariatric sugery patients. Methodology: This is a qualitative analysis in the form of integrative literature review, the theme chosen clearly and explicitly: "What is the metabolic profile of cholecystokinin and its effect on post-bariatric sugery patients?". After formulating the guiding question, the following keywords in Portuguese, English and Spanish were chosen: "bariatric surgery", "bariatric surgery", "cirugía bariátrica"; "cholecystokinin", "cholecystokinin", "cholecystokinin"; "fome", "hunger", "hambre"; "satiety response", "satiety response", "respuesta de saciedad", "Roux-en-Y anastomosis", "anastomosis Roux-en-Y", and "anastomosis en-Y de Roux", through the combination of the controlled descriptors, Medical Subjetc Heading (MeSH) and the Health Science Descriptors (DeCS) resources, as well as the Boolean operators "AND" and "OR". In the databases Latin American and Caribbean Literature on Health Sciences (LILACS), Virtual Health Library (VHL), PubMed, Scientific Electronic Library Online (SciELO) and Google Scholar, a search for clinical trials conducted in humans from 2012 to 2022 was performed. Results: 2,038 articles were identified. The final sample of this review consisted of eleven scientific articles; of these, four were found in the VHL database, two in PubMed, and five in Google Scholar. Thus, concepts about the digestion process and the hormones involved, bariatric surgery techniques and their hormonal effects, were observed in each of the selected articles. Conclusions: Cholecystokinin, a gastrointestinal hormone, is one of the major endocrine satiety signals. It is observed that with gastroplasty, the levels of the hormone CCK are elevated; thus, besides increasing satiety, cholecystokinin aids in weight loss. Therefore, bariatric surgery is highly effective in improving the patient's quality of life
