Objective. Laparoscopic sleeve gastrectomy (LSG) was considered mainly as a restrictive procedure due to anatomic alterations in the upper gastrointestinal tract. Additionally, due to neurohormonal alterations, LSG modifies the gastrointestinal motility, which controls appetite and feeling of satiety. Aim. The aim of the study was to review the impact of laparoscopic sleeve gastrectomy on gastrointestinal motility. Material and Methods. A search of the medical literature was undertaken in Pubmed, Web of Science, and Cochrane library. Esophageal, gastric, bowel motility were assessed separately. Results. Nine studies assessed esophageal motility. The data remain debatable attributing to the heterogeneity of follow-up timing, surgical technique, bougie size, and distance from pylorus. The stomach motility was assessed in eighteen studies. Functionally, the sleeve was divided into a passive sleeve and an accelerated antrum. All scintigraphic studies revealed accelerated gastric emptying after LSG except of one. Patients demonstrated a rapid gastroduodenal transit time. The resection of the gastric pacemaker had as a consequence aberrant distal ectopic pacemaking or bioelectrical quiescence after LSG. The bowel motility was the least studied. Small bowel transit time was reduced; opposite to that the initiation of cecal filling and the ileocecal valve transit was delayed. Conclusion. Laparoscopic sleeve gastrectomy has impacts on gastrointestinal motility. The data remain debatable for esophageal motility. Stomach and small bowel motility were accelerated, while the initiation of cecal filling and the ileocecal valve transit was delayed. Further pathophysiological studies are needed to evaluate the correlation of motility data with clinical symptoms.
