Aim-Background:The aim of the present review is to evidence the differences in the nature of PCS between open and laparoscopic cholecystectomy and also to examine how this condition has evolved over the years. In 5 to 40% of patients with cholelithiasis, regardless of the type of surgery, the symptoms persist postoperatively, leading to the development of the so-called postcholecystectomy syndrome (PCS). The time of the onset of symptoms ranges from 2 days to 25 years after cholecystectomy.Methods: A total number of 926 articles were found as a literature reference pool. We searched English language articles published in Medline, Scopus and google scholar. Only review articles were retrieved because no comparative studies or prospective clinical trials were found to provide statistically significant conclusions. The final group of articles was reviewed, and a total of 57 papers were used for the present review.
Results:The literature is conflicting as concerns the pathophysiology and the aetiology of PCS. Regardless of the type of surgery, it seems that PCS is correlated to age and sex. The prevailing view is that retained or recurrent gallstones, gallbladder remnants and Sphincter of Oddi dysfunction are the primary causes. Moreover, systemic diseases of the gastrointestinal (GI) tract, cardiac disorders, autoimmune diseases, nervous system and psychological distress can mimic PCS symptoms. Nonetheless, there are many available techniques regarding diagnosis and treatment. Nowadays, the majority of researchers endorse ERCP as the gold standard for diagnosis and treatment.
Conclusion:The preoperative meticulous investigation of patients with cholelithiasis is mandatory in order to identify coexisting disorders related to PCS, achieve a better therapeutic approach, and principally reduce PCS incidence.
