Introduction Gastric submucosal tumors (G-SMTs) vary in malignancy risk, with surgical resection as the standard treatment. Although endoscopic resection (ER) offers a less invasive approach, its outcomes remain unclear compared to laparoscopic resection (LR). This study evaluates the safety and efficacy of ER and LR for G-SMTs. Materials and Methods A systematic review and meta-analysis included articles comparing ER and LR for G-SMTs. Primary outcome was complete resection rate. Results Nineteen studies included 673 patients in the ER group and 521 in the LR group. Analysis of the complete resection rate favored LR with RR 0.98 (95% CI 0.97-0.99, p<0.01). ER showed favor in operative time (95% CI -54.46; -24.97, p<0.01), blood loss (95% CI -55.74; -12.70, p<0.01), time to oral intake (95% CI -1.64; -0.33, p<0.01), and hospital stay (95% CI -2.18; -0.59, p<0.01). A subgroup analysis of endoscopic full-thickness resection (EFTR) vs LR showed no significant difference in complete resection rate (RR 0.98, 95% CI 0.95; 1.01, p=0.18). Conclusions LR may have a higher complete resection rate, but ER provides better short-term outcomes. Full-thickness resection, when performed, achieved a comparable resection rate to LR, suggesting potential for broader adoption with further technical advancements.
