Abstract

Introduction: The gold-standard procedure to address malignant gastric outlet obstruction (MGOO) is surgical gastrojejunostomy (SGJJ). Two endoscopic alternatives have also been proposed: the endoscopic stenting (ES) and the endoscopic ultrasound-guided gastroenterostomy (EUS-G). This study aimed to perform a thorough and strict meta-analysis to compare EUS-G with the SGJJ and ES in treating patients with MGOO.

Materials And Methods: Studies comparing EUS-G to endoscopic stenting or SGJJ for patients with MGOO were considered eligible. We conducted online searches in primary databases (MEDLINE, EMBASE, Lilacs, and Central Cochrane) from inception through October 2021. The outcomes were technical and clinical success rates, serious adverse events (SAEs), reintervention due to obstruction, length of hospital stay (LOS), and time to oral intake.

Results: We found similar technical success rates between ES and EUS-G but clinical success rates favored the latter. The comparison between EUS-G and SGJJ demonstrated better technical success rates in favor of the surgical approach but similar clinical success rates. EUS-G shortens the LOS by 2.8 days compared with ES and 5.8 days compared with SGJJ. Concerning reintervention due to obstruction, we found similar rates for EUS-G and SGJJ but considerably higher rates for ES compared with EUS-G. As to AEs, we demonstrated equivalent rates comparing EUS-G and SGJJ but significantly higher ones compared with ES.

Conclusion: Despite being novel and still under refinement, the EUS-G has good safety and efficacy profiles compared with SGJJ and ES.
