Pancreato-biliary endoscopy: History of endoscopic biliary drainage

EUS-guided hepaticogastrostomy versus percutaneous transhepatic biliary drainage after failed ERCP: A propensity score-matched analysis

Background and study aims Percutaneous transhepatic biliary drainage (PTBD) is the traditional second-line option after unsuccessful endoscopic retrograde cholangiopancreatography (ERCP). Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HG) is a viable alternative to PTBD. Our study aimed to compare outcomes of EUS-HG and PTBD for benign and malignant biliary diseases following failed ERCP. Patients and methods This single-center study retrospectively analyzed patients undergoing EUS-HG and PTBD for benign and malignant biliary disorders. A propensity score-matched analysis was performed using age, sex, and Charlson Comorbidity Index. The primary outcome was clinical success, which we defined as a decrease in total bilirubin by ≥ 50% at 2 weeks for malignant disease and resolution of the biliary disorder for benign disease. Results In total, 41 patients underwent EUS-HG and 138 patients underwent PTBD. After propensity score matching in a 1:2 ratio, 32 EUS-HG patients were matched with 64 PTBD. Technical success was achieved in 29 of 32 (91%) for EUS-HG and 63 of 64 (98%) for PTBD ( P =0.11). Clinical success was 100% for EUS-HG and 75% for PTBD ( P =0.0021). EUS-HG was associated with a lower adverse event rate (EUS-HG 13% vs. PTBD 58%, P <0.0001), shorter procedure duration (median 60 vs. 115 minutes, P <0.0001), shorter post-procedure length of stay (median 2 vs. 4 days, P <0.0001), and fewer reinterventions (median 1 vs. 3, P <0.0001). Conclusions Our results suggest that EUS-HG is superior to PTBD in the treatment of benign and malignant biliary disorders after failed ERCP.

Covered self-expandable metallic stent versus plastic stent for preoperative endoscopic biliary drainage in patients with pancreatic cancer: a multi-center retrospective cohort study

BACKGROUND

Expanding indications for neoadjuvant chemotherapy (NAC) for resectable pancreatic cancer prolong the period from diagnosis to surgery. In resectable pancreatic cancer with malignant biliary obstruction (MBO), the biliary drainage method without any biliary events is ideally required to safely perform NAC as planned. Plastic stents (PS) have been traditionally used for preoperative biliary drainage; however, recently, covered self-expandable metallic stents (CSEMS) have emerged as a tool for preoperative biliary drainage.

AIMS

To compare CSEMS with PS for preoperative biliary drainage in the management of resectable pancreatic cancer with MBO.

METHODS

In this multicenter retrospective cohort study, we compared CSEMS with PS for preoperative biliary drainage in patients with pancreatic cancer at three tertiary care centers between 2008 and 2019.

RESULTS

Of the 120 enrolled patients, 45 underwent CSEMS and 75 underwent PS. No significant difference was observed in the basic characteristics between the groups. The rate of recurrent biliary obstruction (RBO) was significantly lower and the time to RBO was significantly longer in the CSEMS group. In multivariate analysis, CSEMS was an independent factor for a longer RBO. However, pancreatitis and cholecystitis were more common in the CSEMS group. The surgery-related adverse events were not significantly different between the two groups, except for longer surgery time and time to discharge in the CSEMS group.

CONCLUSIONS

CSEMS for preoperative endoscopic biliary drainage in patients with pancreatic cancer reduced RBO, although the risk for pancreatitis or cholecystitis could be increased.
