[Endoscopic retrograde biliary drainage for malignant obstructive jaundice].

This paper reports 19 cases of malignant obstructive jaundice treated by endoscopic retrograde biliary drainage (ERBD). Since 1989, ERBD is a palliative treatment of inserted into the obstructed bile duct by endoscopy. This method can efficiently relieve biliary obstruction. Elimination jaundice reduces some discomforts such as irritating pruritus. It also increases the appetite and improve patient's general physical condition. Temporary preoperative decompression of the bile ducts in seriously jaundiced patients should result in a significant reduction postoperative morbidity and mortality. There were 9 patients of this group who underwent operation after a short period of drainage, These patients weren't found any postoperative complication. ERBD also be used for palliative decompression of the bile duct in cases of inoperable cancer. The method was carried out in 7 inoperable patients of this group. Results were satisfactory.

[Shape-memory nitinol alloy endoprosthesis for malignant biliary strictures].

A new design of endoprosthesis, made of shape-memory nitinol alloy, was used to replace the currently used one, which was soon clogged with bile mud. After nitinol wire coil stent was slenderized in ice water, it was inserted into the strictured bile duct by endoscopy or operation. When nitinol wire coil was positioned in a narrowed biliary segment, normal saline heated to 39 degrees C was rapidly hand-injected into the lumen of the inner transport catheter to make the alloy coil to resume its original shape with a length of 3 to 10cm, and a diameter of 5 to 10mm. Since June 1991, 13 patients with malignant biliary strictures were treated with nitinol endoprosthesis. The follow-up period ranged from 1 to 16 months (average 6 months). Biliary sludge was not found in the endoprosthesis during the period. The results suggested that shape-memory nitinol alloy endoprosthesis could maintain long term patency without severe infection or obstruction due to biliary sludge.
