[Internal biliary drainage in the "rendezvous" procedure. Combined transhepatic endoscopic retrograde methods]
Deutsche Medizinische Wochenschrift (1946)
|May 8, 1987
Summary
The rendezvous procedure effectively places internal biliary drainage for malignant bile duct blockages, achieving a 95% success rate with minimal complications. This technique offers a reliable solution for challenging cases.
Area of Science:
- Gastroenterology
- Interventional Radiology
- Oncology
Context:
- Malignant biliary strictures often require internal biliary drainage for palliation.
- Inoperable cases present significant challenges for conventional drainage techniques.
- The "rendezvous procedure" integrates percutaneous transhepatic and endoscopic retrograde cholangiography.
Purpose:
- To evaluate the efficacy and safety of the "rendezvous procedure" for internal biliary drainage in patients with inoperable malignant biliary stenosis.
- To assess the technical success rate, procedure time, and complication profile of this combined approach.
Summary:
- The "rendezvous procedure" successfully positioned internal biliary drains in 95% of 22 patients with malignant biliary stenosis.
- The technique involves transhepatic advancement of a guide wire into the duodenum, followed by endoscopic drain placement.
- The Mori-knife technique facilitated papillotomy in cases where conventional methods failed, and the transhepatic guide aided in overcoming anatomical challenges like Billroth II gastrectomy.
Impact:
- This minimally invasive approach offers a high success rate and low complication rate for managing difficult biliary obstructions.
- It provides an effective alternative for patients with inoperable malignant stenoses, improving palliation and quality of life.
- The procedure's adaptability, particularly in post-gastrectomy patients, broadens its applicability in complex biliary interventions.
