BACKGROUNDS: Postoperative percutaneous choledochoscopy via T tube sinus tract is a common modality for treating retained intrahepatic stones in China. We report a rare complication of postoperative choledochoscopy for treating retained hepatolithiasis: T tube sinus tract duodenal fistula.
METHODS: From January 2003 to December 2018, intrahepatic duct stones with or without common bile duct stones were detected in 1031 patients. Fifteen of the 1031 patients with intrahepatic stones developed a T tube sinus tract duodenal fistula that was diagnosed by cholangiography and choledochoscopy.
RESULTS: The incidence of T tube sinus tract duodenal fistula in patients with retained intrahepatic stones being treated by postoperative choledochoscopy is 1.45% (15/1031) in this series. The chi-squared test showed that hypoalbuminemia (P = 0.003), long duration of T tube (P = 0.002), and high frequency of procedure (P = 0.008) might be associated with the occurrence of T tube sinus tract duodenal fistula. The logistic regression analysis demonstrated that hypoalbuminemia might be the independent risk factor for this special fistula (P = 0.037).
CONCLUSIONS: Hypoalbuminemia, long time placement of T tube in situ and high frequency of procedure are probably the main causes of the T tube sinus tract duodenal fistula. Placement of T tube in correct way and improving nutritional status may be the key points to prevent the formation of T tube sinus tract duodenal fistula.
