Gallstones are described as one of the most common diseases of the digestive
system. It can affect 15% of the adult population. The standard of treatment for
symptomatic gallbladder stones is laparoscopic cholecystectomy. Among its most
outstanding features are its effectiveness and low complication rate. In a proportion
of patients, the image of side effect, with a name known as Postcholecystectomy
Syndrome (PCS), occurs after a successful surgery, for some time, with medical
implications. In the context of PCS, a variety of clinical symptoms are included,
including diarrhea, abdominal pain, nausea, indigestion, or bloating. It may be
immediately following an operation or many months or years afterwards. The
etiology of PCS is complex and ambiguous, including both organic causes (e.g.,
residual stones, sphincter of Oddi dysfunction), and extra-biliary causes (e.g.,
irritable bowel syndrome). The variety of symptoms and causes makes the
diagnosis of PCS difficult and requires a multidisciplinary approach. This paper
will provide an overview of the current state of knowledge on PCS, with a focus on
the mechanisms of symptom onset, diagnostic options and available therapeutic
strategies, including the treatment of diarrhea caused by bile acid disorders.
