Post-cholecystectomy syndrome: Descriptive analysis of a prospective cohort

Abstract

Introduction. Post-cholecystectomy syndrome (PCS) was described more than 70 years ago and is defined as the presence of gastrointestinal (GI) symptoms that may persist after cholecystectomy or can present as new symptoms. This little-known syndrome can appear from a few months to several years after surgery and occurs between 5% and 40% of patients. Method. Prospective cohort study, which included patients who underwent laparoscopic cholecystectomy in three surgical units in Bogotá, Colombia, during a period of eight months, with periodic follow-up for two years. PCS was defined as the presence of at least one GI symptom from the first month after surgery. Results. Three-hundred and eighty patients were included, of which 183 (48.2%) developed the syndrome. Age had a statistically significant difference between those who developed PCS and those who did not (p=0.024). Diarrhea was the only preoperative symptom associated with the development of PCS. Post-cholecystectomy syndrome was found in 42.1% at the first month of follow-up and in 17.4% at the second year. Conclusions. Post-cholecystectomy syndrome occurs in a significant percentage of patients. Consistent with the literature, preoperative diarrhea was found to be an independent risk factor for the development of the syndrome. Adequate follow-up of patients after cholecystectomy is recommended.
