Afferent loop syndrome (ALS) is a known adverse event following Whipple procedure. A palliative surgical bypass is invasive and can only be performed in a limited selection of patients [1]. Recently, a minimally invasive approach, endoscopic ultrasound-guided gastrojejunostomy (EUS-GJ) using a lumen-apposing metal stent (LAMS), has been reported [2] [3] [4]. The LAMS has the advantages of preventing both stent migration and leakage of fluid. However, the LAMS is not available in many countries and is more expensive than the conventional fully covered self-expandable metal stent (FCSEMS). Therefore, we developed a method involving an FCSEMS with antimigration properties, comprising a large-loop double-pigtail plastic stent within an FCSEMS ([Fig. 1]). Herein, we describe technical tips for EUS-GJ using the modified stent system ([Video 1]).

A 73-year-old man who had undergone a pancreaticoduodenostomy for pancreatic cancer presented with fever and abdominal pain. Computed tomography (CT) revealed ALS caused by local recurrence of the cancer ([Fig. 2]). Although plastic stents were placed into the dilated afferent loop using balloon assisted-enteroscopy ([Fig. 3]), his clinical condition did not improve.

We attempted EUS-GJ. The dilated afferent loop was punctured from the stomach with a 19-gauge fine-needle aspiration needle, through which a 0.025-inch guidewire was inserted. A cautery dilator was used to make an incision into the needle tract and a 4-mm balloon catheter was used to dilate the tract. A 10 mm × 8 cm FCSEMS (BONA stent; Standard Sci-Tech Inc., Seoul, Korea) was deployed to appose the dilated afferent loop and the stomach. Finally, a 7 Fr × 8 cm large-loop double-pigtail plastic stent (Double Pigtail; Medi-Grobe GmbH, Germany) was placed through the FCSEMS ([Fig. 4]). The patient’s symptoms rapidly disappeared.

CT 10 days after the procedure showed improvement of the dilated afferent loop ([Fig. 5]).

This modified stent system is helpful in preventing stent migration and leakage of fluid, similarly to LAMS. In addition, it has a lower cost compared with LAMS. The system may be a treatment option when performing EUS-GJ for ALS.
