Endoscopic Ultrasound-Guided Gastroenterostomy for Afferent Loop Syndrome: Hideyuki Shiomi, Arata Sakai, Ryota Nakano, Shogo Ota, Takashi Kobayashi, Atsuhiro Masuda, Hiroko Iijima; Clin Endosc 2021;54(6):810-817. Published online November 15, 2021; DOI: https://doi.org/10.5946/ce.2021.234

Abstract PDF PubReader ePub

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.

Endoscopic Self-Expandable Metal Stent Placement for Malignant Afferent Loop Obstruction After Pancreaticoduodenectomy: A Case Series and Review: Arata Sakai, Hideyuki Shiomi, Takao Iemoto, Ryota Nakano, Takuya Ikegawa, Takashi Kobayashi, Atsuhiro Masuda, Yuzo Kodama; Clin Endosc 2020;53(4):491-496.

Abstract PDF PubReader ePub

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.
