Post-cholecystectomy syndrome: A cohort study from a single private tertiary center

Objectives: Although post-cholecystectomy syndrome (PCS) is a well-recognized complication, there are few reports arising from KSA. The effect of sleeve gastrec-tomy or endoscopic retrograde cholangiopancreatog-raphy (ERCP) stenting on the development of PCS is unknown. We aimed to measure the possible factors affecting the development of PCS, such as symptom duration, comorbidities, previous bariatric surgery, ERCP stent insertion, surgical intervention, conversion to open surgery and complication rate.Methods: This was a prospective cohort and observa-tional study conducted at a single, private tertiary center. We included 167 patients who underwent surgery for gallbladder disease between October 2019 and June 2020. The patients were classified into two groups according to their PCS status (PCS+ vs. PCS-).Results: Thirty-nine patients were PCS+ (23.3%). There was no significant difference between the two groups with regards to age, gender, BMI, ASA score, smoking, comorbidities, duration of symptoms, previous bariatric surgery, ERCP, stent insertion or sphincterotomy. Chronic cholecystitis was the predominant histopathol-ogy in 83% (139/167) of patients. The most frequent causes of PCS included biliary system dysfunction, bile salt-induced diarrhea, gastritis, gastroesophageal reflux disease, and retained stones. Overall, 71.8% (28/39) of patients had incident PCS; the remaining patients had persistent PCS.Conclusions: PCS is a neglected complication that was observed in 25% of patients mainly in the first year. Surgeon awareness can assist with patient diagnosis, preoperative selection and education. Furthermore, the history of ERCP stenting, sphincterotomy, or sleeve gastrectomy seems to be unrelated to PCS development.
