Transcatheter arterial embolisation (TAE) to treat acute upper gastrointestinal bleeding secondary to gastric cancer: A systematic review and meta-analysis.

Acute upper gastrointestinal bleeding (UGIB) secondary to gastric cancer presents a significant clinical challenge due to its high morbidity and mortality rates. Transcatheter arterial embolisation (TAE) has emerged as a potential therapeutic option for managing this condition, especially in the context of failed endoscopic management. This systematic review aims to evaluate the efficacy and safety of TAE in treating acute upper gastrointestinal (GI) bleeding caused by gastric cancer. A systematic search of medical databases, including PubMed, MEDLINE, and EMBASE, was conducted for studies published between 2000 and 2023. Included studies reported on the use of TAE for acute upper GI bleeding specifically due to gastric cancer, including retrospective analyses, case reports, and cohort studies. Demographics and clinical outcomes were reported. A total of 7 studies met the inclusion criteria, all being retrospective in nature. The overall technical success rate of TAE was 94.9 %. Overall clinical success rates were 72 % with a 95 % confidence interval (CI) of 66-79 %. Overall rebleeding rates were 11 % with a 95 % CI of 3-18 %. Major complications were reported in 2.4 % of patients, including ischemic complications and organ perforation. The overall 30-day mortality rate was 26.4 %, primarily due to underlying disease progression rather than procedural complications. TAE is an effective and safe intervention for managing acute upper GI bleeding secondary to gastric cancer, with high success rates. TAE should be considered a viable treatment modality for this challenging condition, particularly for patients who are being considered for neoadjuvant therapy or indeed those not suitable candidates for curative surgical intervention.
