Same-session double EUS-guided bypass versus surgical gastroenterostomy and hepaticojejunostomy: an international...

Gastric outlet and biliary obstruction are common manifestations of GI malignancies and some benign diseases for which standard treatment would be surgical gastroenterostomy and hepaticojejunostomy (ie, "double bypass"). Therapeutic EUS has allowed for the creation of an EUS-guided double bypass. However, same-session double EUS-guided bypass has only been described in small proof-of-concept series and lacks a comparison with surgical double bypass.

A retrospective multicenter analysis was performed of all consecutive same-session double EUS-guided bypass procedures performed in 5 academic centers. Surgical comparators were extracted from these centers' databases from the same time interval. Efficacy, safety, hospital stay, nutrition and chemotherapy resumption, long-term patency, and survival were compared.

Of 154 identified patients, 53 (34.4%) received treatment with EUS and 101 (65.6%) with surgery. At baseline, patients undergoing EUS exhibited higher American Society of Anesthesiologists scores and a higher median Charlson Comorbidity Index (9.0 [interquartile range {IQR}, 7.0-10.0] vs 7.0 [IQR, 5.0-9.0], P < .001). Technical success (96.2% vs 100%, P = .117) and clinical success rates (90.6% vs 82.2%, P = .234) were similar when comparing EUS and surgery. Overall (11.3% vs 34.7%, P = .002) and severe adverse events (3.8% vs 19.8%, P = .007) occurred more frequently in the surgical group. In the EUS group, median time to oral intake (0 days [IQR, 0-1] vs 6 days [IQR, 3-7], P < .001) and hospital stay (4.0 days [IQR, 3-9] vs 13 days [IQR, 9-22], P < .001) were significantly shorter.

Despite being used in a patient population with more comorbidities, same-session double EUS-guided bypass achieved similar technical and clinical success and was associated with fewer overall and severe adverse events when compared with surgical gastroenterostomy and hepaticojejunostomy.
