Abstract

Background

Little is known regarding the risk of tumor dissemination when percutaneous biliary drainage is used before surgical resection of perihilar cholangiocarcinoma (PHC). We aimed to compare the incidence of tumor dissemination after preoperative endoscopic nasobiliary drainage (ENBD) with that after percutaneous transhepatic biliary drainage (PTBD) for PHC.

Methods

Data from 208 consecutive patients who underwent PHC resection between 2000 and 2013 were retrospectively analyzed. The influence of drainage type on incidence of tumor dissemination was examined. Seventy-six patients underwent ENBD (37%), 87 underwent PTBD (42%), and 45 underwent surgery without preoperative biliary drainage (WD, 22%).

Results

The respective 2- and 5-year estimated cumulative incidences of tumor dissemination in the ENBD group (11.8/14.6%) were lower than in the PTBD group (28.8/35.9%, p = 0.003) and equivalent to that in the WD group (11.2/15.9%, p = NS). PTBD (hazard ratio [HR] vs. ENBD, 2.80) was an independent risk factor for postoperative tumor dissemination in the multivariate analysis. The 2- and 5-year disease-specific survival rates were higher in the ENBD group (67.6/47.3%) than in the PTBD group (56.6/27.8%, p = 0.032) and equivalent to that in the WD group (64.9/53.8%, p = NS). However, drainage type was not an independent risk factor in multivariate analysis of disease-specific survival.

Conclusion

For patients with PHC, the associated risk of postoperative tumor dissemination in the ENBD group was lower than in the PTBD group and equivalent to that in the WD group. Thus, ENBD is the ideal procedure for preoperative biliary drainage.

S3-Leitlinie „Diagnostik und Therapie des Karpaltunnelsyndroms“

Karpaltunnelsyndrom BDC Leitlinien Webinare
CME: 2 Punkte

Das Karpaltunnelsyndrom ist die häufigste Kompressionsneuropathie peripherer Nerven. Obwohl die Anamnese mit dem nächtlichen Einschlafen der Hand (Brachialgia parästhetica nocturna) sehr typisch ist, ist eine klinisch-neurologische Untersuchung und Elektroneurografie in manchen Fällen auch eine Neurosonografie erforderlich. Im Anfangsstadium sind konservative Maßnahmen (Handgelenksschiene, Ergotherapie) empfehlenswert. Bei nicht Ansprechen der konservativen Therapie oder Auftreten von neurologischen Ausfällen ist eine Dekompression des N. medianus am Karpaltunnel indiziert.
