Abstract
Introduction
During laparoscopic cholecystectomy (LC), common bile duct (CBD) visualization either directly or with cholangiography (IOC) is less routine. Cholangiography can be used to identify and possibly prevent bile duct injury (BDI), which is a dreaded complication of cholecystectomy. The purpose of our study was to evaluate the trend of IOC/CBD exploration and BDI during LC for benign disease.
Methods
A state-wide database (SPARCS) was used to identify all LC for benign biliary non-obstructive and obstructive disease between 2000 and 2014 in the state of New York. ICD-9 and CPT codes were used to identify IOC/CBD exploration and BDI. Multivariable logistic regression models were used in examining the linear trend in the risk of complication, 30-day readmission, 30-day ED visits, and BDI among all cholangiogram patients after controlling for possible confounding factors.
Results
During 2000–2014, 391,945 patients underwent laparoscopic cholecystectomy. The trend of IOC/CBD exploration performed significantly decreased for LC overall (12.37–10.44%, relative risk = 0.98, p <.0001) and particularly, in the outpatient setting (10.77–7.52%, relative risk = 0.96, p value <.0001). Among patients with IOC, overall complication rate, 30-day readmission rate, and 30-day ED visit rates increased. When looking at overall complication rate, there was an increase by about 4% per year (relative risk = 1.04, p value <.0001). After controlling for confounding factors, the complication risk and 30-day ED visit risk increased through years, while the 30-day readmission risk did not have significant change. Risk of BDI also increased significantly (p = 0.03).
Conclusion
In an era of laparoscopy, the rate of IOC/CBD exploration during LC has significantly decreased, while BDI significantly increased.
