EVALUATION OF THE FREQUENCY AND PREDISPOSING FACTORS OF RETAINED STONE AFTER LAPARASCOPIC CHOLECYCTECTOMY IN URMIA EMAM KHOMEINI HOSPITAL

摘要

Background & Aims : Laparoscopic cholecystectomy is the treatment of choice for symptomatic gallstones. The term postcholecystectomy syndrome (PCS) comprises a heterogeneous group of symptoms and findings in patients who have previously undergone cholecystectomy.With the number of cholecystectomies being performed increasing in the laparoscopic era the number of patients presenting with PCS is also likely to increase. This study aimed to investigate the frequency and predisposing factors of retained stone after laparascopic cholecyctectomy to the referred the patient with CBD stone for preoperative endoscopic retrograde cholangiopancreatography (ERCP). Materials &Methods : A total of 993 patients were evaluated after laparascopic cholecyctectomy in Urmia Imam Khomeini Teaching Hospital between January 2011 and February 2014. The patients were categorized into two groups according to the presence or absence of retained stone after laparascopic cholecyctectomy , and the risk factors was compared between them. Results : Patients were 800 females and 193 males with a mean age of 48.70± 16.82 (range13-94) years. Retained stone after laparascopic cholecyctectomy occurred in 47 patients (4.75%). The two groups were comparable in terms of patient age, sex, body mass index (BMI) , serum level of BIL, ALP, AST, ALT and CBD and intrahepatic bile duct diameter before operation and HTN, DM and duration of admit. The mean level of age and duration of admit and pre-operative serum BIL, ALP, AST, ALT and CBD and intrahepatic bile duct diameter before operation and HTN was significantly higher in the cases with retained stone after laparascopic cholecyctectomy . Conclusion : According to the results of the present study, the measurement of serum BIL, ALP, AST, ALT, and CBD and intrahepatic bile duct diameter before operation may be capable of predicting retained stone after laparascopic cholecyctectomy .
