Alterations of digestive motility after bariatric surgery.

ABSTRACT

Bariatric surgery can induce changes in digestive motility that are de novo or secondary to an improvement or aggravation of previous disorders due to obesity. Alterations of digestive motility are frequently part of the mechanism of action and a result of surgery. They are not rare and they are not always associated with an increase in weight loss but can lead to the negative consequences on quality of life, which are more or less reversible as a real surgical complication. Knowledge of these complications has become essential, especially in this period when bariatric surgery often concerns patients who have already undergone an operation. Thus, the changes in digestive motility after bariatric surgery and the complications that may result from them must be known and considered to adapt surgical techniques to each patient, both in the case of a first intervention and in the case of a reoperation, which is becoming more and more frequent. The objective of this review is to synthesize alterations of esophageal and gastro-intestinal motility secondary to bariatric surgical procedures.
