Background: Duodenal stump fistula (DSF) after gastrectomy is a complication with a high mortality rate. We report a series of patients with postoperative DSF treated with percutaneous transhepatic biliary drainage and occlusion balloon (PTBD-OB). The aim of this study is to explore the feasibility and efficacy of PTBD-OB in the treatment of DSF.
Patients and methods: Six patients developing DSF underwent PTBD-OB because of high DSF output and because medical and surgical management was unsuccessful. In these patients, an occlusion balloon was percutaneously inserted into the common bile duct and a biliary drain was positioned above the balloon to obtain external drainage of bile.
Results: In all cases, percutaneous access to the biliary tree was achieved. Patients maintained the PTBD-OB for a median of 43 days. In all patients, DSF output decreased after PTBD-OB placement from a median of 500 to 100 ml/day (p = 0.02). The DSF resolved in three patients and three patients died of sepsis, but in two of them, death was related to other digestive fistulas that developed before PTBD-OB placement.
Conclusions: This paper presents the first published series on DSF management with PTBD-OB and shows that it is a feasible and safe procedure which reduces DSF output.
