Endoscopic nasobiliary drainage for obstructive jaundice using either a 5 Fr or 7 Fr catheter: a prospective, randomized trial.

ABSTRACT:

Background

The influence of size on the effectiveness of nasobiliary catheters has not yet been studied. We compared biliary drainage effectiveness and procedure-related discomfort and adverse events in 5 French (Fr) and 7 Fr nasobiliary catheters.

Methods

We prospectively studied 100 patients undergoing endoscopic biliary drainage for obstructive jaundice, who were randomly allocated to a 5 Fr or 7 Fr nasobiliary catheter group. As the primary endpoint, the effectiveness was evaluated by the serum total bilirubin decreasing rate and the success rate of jaundice relief. As the secondary endpoint, the degree of discomfort was investigated using a questionnaire survey after catheter removal.

Results

The bilirubin decrease rate was significantly higher in the 7 Fr catheter group than in the 5 Fr group (53.0 ± 21.4% vs 40.5 ± 29.9%, respectively; P = 0.019). The success rate of jaundice relief tended to be higher in the 7 Fr catheter group, although the difference was not statistically significant (98% vs 88%, respectively; P = 0.056). The questionnaire survey demonstrated that total discomfort was significantly greater in the 7 Fr group (3.9 ± 1.5 vs 3.2 ± 1.4, respectively; P = 0.018). Larger-diameter catheters tended to increase difficulty in eating, although the difference between the groups was not statistically significant.

Conclusions

7 Fr nasobiliary catheters are recommended for patients requiring rapid and reliable relief of obstructive jaundice. However, because they can cause greater discomfort, 5 Fr nasobiliary catheters are preferred in other settings.

Project description:To compare the outcomes of preoperative endoscopic nasobiliary drainage (ENBD) and endoscopic retrograde biliary drainage (ERBD) in patients with malignant distal biliary obstruction prior to pancreaticoduodenectomy (PD).Data from 153 consecutive patients who underwent preoperative endoscopic biliary drainage prior to PD between January 2009 and July 2016 were analyzed. We compared the clinical data, procedure-related complications of endoscopic biliary drainage (EBD) and postoperative complications of PD between the ENBD and ERBD groups. Univariate and multivariate analyses with odds ratios (ORs) and 95% confidence intervals (95%CIs) were used to identify the risk factors for deep abdominal infection after PD.One hundred and two (66.7%) patients underwent ENBD, and 51 (33.3%) patients underwent ERBD. Endoscopic sphincterotomy was less frequently performed in the ENBD group than in the ERBD group (P = 0.039); the EBD duration in the ENBD group was shorter than that in the ERBD group (P = 0.036). After EBD, the levels of total bilirubin (TB) and alanine aminotransferase (ALT) were obviously decreased in both groups, and the decreases of TB and ALT in the ERBD group were greater than those in the ENBD group (P = 0.004 and P = 0.000, respectively). However, the rate of EBD procedure-related cholangitis was significantly higher in the ERBD group than in the ENBD group (P = 0.007). The postoperative complications of PD as graded by the Clavien-Dindo classification system were not significantly different between the two groups (P = 0.864). However, the incidence of deep abdominal infection after PD was significantly lower in the ENBD group than in the ERBD group (P = 0.019). Male gender (OR = 3.92; 95%CI: 1.63-9.47; P = 0.002), soft pancreas texture (OR = 3.60; 95%CI: 1.37-9.49; P = 0.009), length of biliary stricture (≥ 1.5 cm) (OR = 5.20; 95%CI: 2.23-12.16; P = 0.000) and ERBD method (OR = 4.08; 95%CI: 1.69-9.87; P = 0.002) were independent risk factors for deep abdominal infection after PD.ENBD is an optimal method for patients with malignant distal biliary obstruction prior to PD. ERBD is superior to ENBD in terms of patient tolerance and the effect of biliary drainage but is associated with an increased risk of EBD procedure-related cholangitis and deep abdominal infection after PD.
