Preoperative Biliary Drainage With Metal Versus Plastic Stents in Periampullary Cancer

Seoul National University Hospital60 enrolled

Overview

Currently, routine preoperative biliary drainage (PBD) was not recommended. However, PBD is still necessary in case of patients with cholangitis or very high level of bilirubin or patients who are expected to receive delayed surgery. The aim of this clinical trial is to demonstrate non-inferiority of uncovered self-expandable metal stent to plastic stent for PBD by endoscopic retrograde cholangiopancreatography in patients with periampullary cancer undergoing curative intent pancreaticoduodenectomy.

Jaundice is one of the most common symptoms in patients with periampullary cancers including pancreatic cancer, common bile duct (CBD) cancer, ampulla of Vater (AoV) cancer, and duodenal cancer. Traditionally, preoperative biliary drainage (PBD) was routinely performed in these cancers because it might favorably influence sepsis, endotoxemia, and intravascular coagulation. However, a recent randomized control study reported that routine PBD in patients undergoing surgery for cancer of the pancreatic head increases the rate of complications. Therefore, routine PBD was not recommended. However, PBD is still necessary in case of patients with cholangitis or very high level of bilirubin or patients who are expected to receive delayed surgery. In these patients with necessity of PBD, a plastic stent (PS) has been used because it is good for temporary use with cheap prices. However, it is sometimes occluded before surgery or not enough for rapid decompressing jaundice mainly because of its short diameter. In this aspect, a self-expandable metal stent (SEMS) has strength compared to PS because it has a longer diameter which enables rapid decompression with a fewer events of occlusion. However, SEMS is much more expensive than PS and the exact length of stent is more critical. Although there are still lack of evidence which compares the results between PS and SEMS, National Comprehensive Cancer Network (NCCN) guidelines recently recommended the use of a short SEMS for pancreatic adenocarcinoma patients with cholangitis or fever. However, we needed more concrete evidence about this principle.

Outcomes

Primary Outcomes

Reintervention rate until operation

Between preoperative biliary drainage and surgery, reintervention (re-preoperative biliary drainage) would be checked and analyzed.

Time frame: Between preoperative biliary drainage and surgery

Secondary Outcomes

Other complication rate associated with endoscopic stent insertion and stent indwell

Until surgery, preoperative biliary drainage associated with complication would be checked and analyzed.

Time frame: Between preoperative biliary drainage and surgery

Rate of decrease of total bilirubin

Amount of decrease of total bilirubin between preoperative biliary drainage and surgery would be checked.

Time frame: Between preoperative biliary drainage and surgery

Time to operation

Interval between preoperative biliary drainage and surgery would be checked.

Time frame: Between preoperative biliary drainage and surgery

Time to hospital discharge after pancreaticoduodenectomy

Interval between surgery and discharge would be checked.

Time frame: 6 month

Mortality until 3 months after pancreaticoduodenectomy

The mortality rate would be calculated

Time frame: 3 month
