“…These biliary catheters have been placed for varying periods (mean duration of 1.1-19.9 months) in previous studies [13][14]. The endpoint of the treatment is considered to be reached when cholangiography shows the free flow of contrast across the HJ anastomosis into the jejunum and the patient passes a "clinical test" [8,15].…”

“…If the LFTs are not elevated (total bilirubin: <1.3 mg/dl, conjugated bilirubin: <0.4 mg/dl, alkaline phosphatase: <150 U/L) and the obstructive symptoms do not recur, the treatment is considered a success and the catheter is withdrawn. If the LFTs are deranged, then either repeat balloon dilatation is performed with placement of IEBCs or the patient is referred for surgical management [8,[15][16].…”

Background and objectivePercutaneous balloon dilatation followed by long-term internal-external biliary catheter (IEBC) placement is the standard radiological management for postoperative hepaticojejunostomy (HJ) strictures. The treatment is considered successful when cholangiography shows a free flow of contrast across the anastomosis and the patient passes a "clinical test". However, these tests may not be suitable predictors of long-term successful treatment outcomes. The purpose of this study was to assess the utility of biliary manometry in the evaluation of successful treatment outcomes after HJ stricture dilatation and IEBC placement and its efficacy as a tool for early catheter removal. Patients and methodsA total of 14 patients underwent percutaneous balloon dilatation of HJ strictures with IEBC placement. A two-to-three-month interval was maintained between sessions of exchanging or upsizing IEBCs. Biliary manometry was performed after a mean duration of 6.3 months. Intra-biliary pressure of <15 mmHg was considered as the success threshold. ResultsAmong the 14 patients, 11 patients passed initial manometry and had their IEBCs removed and were followed up for a mean duration of 47.8 months. Of these, one patient developed biliary obstruction after six months and underwent repeat HJ stricture dilatation and long-term IEBC placement. Three patients failed manometry and underwent re-dilatation of HJ strictures with IEBC placement. Using Kaplan-Meier survival analysis, the probability of patients remaining stricture-free after HJ stricture dilatation was found to be 100% at three months and 91% at six, 12, 18, 24, 36, and 47.8 months. ConclusionBiliary manometry prevents subjective variations in determining treatment endpoints and helps to assess early catheter removal after percutaneous balloon dilatation of HJ strictures.
