Endoscopic ultrasound-guided gastrojejunostomy with a direct technique without previous intestinal filling using a...

Endoscopic ultrasonography-guided gastrojejunostomy is a minimally invasive method for the management of gastric outlet obstruction. Conventionally, a lumen-apposing metal stent (LAMS) is used to create an anastomosis. However, LAMS is expensive and not widely available. In this report, we described a tubular fully covered self-expandable metallic stent (T-FCSEMS) for this purpose.

Twenty-one patients (15 men [71.4%]; median age, 66 years; range, 40-87 years) were included in this study. A total of 19 malignant (12 pancreatic, 6 gastric, and 1 metastatic rectal cancer) and 2 benign cases were observed. The proximal jejunum was punctured with a 19 G needle. The stomach and jejunum walls were dilated with a 6 F cystotome, and a 20×80 mm polytetrafluoroethylene T-FCSEMS (Hilzo) was deployed. Oral feeding was initiated after 12 to 18 hours and solid foods after 48 hours.

The median procedure time was 33 minutes (range, 23-55 minutes). After two weeks, 19 patients tolerated oral feeding. In patients with malignancy, the median survival time was 118 days (range, 41-194 days). No serious complications or deaths occurred. All patients with malignancy tolerated oral food intake until they expired.

T-FCSEMS is safe and effective. This stent should be considered as an alternative to LAMS for gastric outlet obstruction.
