Background
/Aims: Endoscopic self-expandable metal stent (SEMS) placement is currently the standard technique for treating unresectable malignant distal biliary obstructions (MDBO). Therefore, covered SEMS with longer stent patency and fewer migrations are required. This study aimed to assess the clinical performance of a novel, fully covered SEMS for unresectable MDBO.
Methods
This was a multicenter single-arm prospective study. The primary outcome was a non-obstruction rate at 6 months. The secondary outcomes were overall survival (OS), recurrent biliary obstruction (RBO), time to RBO (TRBO), technical and clinical success, and adverse events.
Results
A total of 73 patients were enrolled in this study. The non-obstruction rate at 6 months was 61%. The median OS and TRBO were 233 and 216 days, respectively. The technical and clinical success rates were 100% and 97%, respectively. Furthermore, the rate of occurrence of RBO and adverse events was 49% and 21%, respectively. The length of bile duct stenosis (<2.2 cm) was the only significant risk factor for stent migration.
Conclusions
The non-obstruction rate of a novel fully covered SEMS for MDBO is comparable to that reported earlier but shorter than expected. Short bile duct stenosis is a significant risk factor for stent migration.

AbstractAbstract PDFPubReaderePub
Afferent loop syndrome (ALS) is a mechanical obstruction of the afferent limbs after gastrectomy with gastrojejunostomy reconstruction. Patients with cancer recurrence require immediate and less invasive treatment because of their poor condition. Percutaneous transhepatic/transluminal drainage (PTD) and endoscopic enteral stenting offer reasonable palliative treatment for malignant ALS but are not fully satisfactory in terms of patient quality of life (QoL) and stent patency. Endoscopic ultrasound-guided gastroenterostomy (EUS-GE) using a lumen-apposing metal stent may address these shortcomings. Clinical data from 11 reports showed that all patients who had undergone EUS-GE had positive technical and clinical outcomes. The adverse event rate was 11.4%, including only mild or moderate abdominal pain, with no severe adverse events. Indirect comparative studies indicated that patients who had undergone EUS-GE had a significantly superior QoL, a higher clinical success rate, and a lower reintervention rate than those who had undergone PTD or endoscopic enteral stenting. Although the evidence is limited, EUS-GE may be considered as a first-line treatment for malignant ALS because it has better clinical outcomes than other less invasive treatments, such as PTD or endoscopic enteral stenting. Further prospective randomized control trials are necessary to establish EUS-GE as a standard treatment for ALS.

AbstractAbstract PDFPubReaderePub
In this study, we assessed a series of our cases in which endoscopic self-expandable metal stents (SEMSs) were used to treat malignant afferent loop obstruction (ALO) that arose after pancreaticoduodenectomy (PD). We retrospectively examined the records of 7 patients who underwent endoscopic SEMS placement for malignant ALO following PD. Clinical success was achieved in all cases. The median procedure time was 30 min (range, 15–50 min). There were no cases of stent occlusion, and no procedure-related adverse events were encountered. All patients died of their primary disease, and the median overall survival period was 155 days (range, 96–374 days). A re-intervention involving endoscopic ultrasound-guided hepaticogastrostomy combined with antegrade stenting was performed for obstructive jaundice and acute cholangitis in 1 case. In conclusion, endoscopic SEMS placement may be an effective and safe treatment for malignant ALO that arises after PD.
