Core Tip
Core Tip: This study compared digestive endoscopic super minimally invasive surgery and laparoscopic wedge resection (Lap MWR) for treating extraluminal gastric tumors originating from the muscularis propria layer (EGT-MP). Analysis of 542 patients revealed that the Lap MWR group had larger tumors, longer operative times, greater blood loss, longer hospital stays, and higher costs, but a lower incidence of adverse postoperative reactions and a simpler medication regimen. Outcomes were location-dependent. For antral EGT-MP, Lap MWR did not prolong surgery or hospitalization and simplified postoperative management. For fundic EGT-MP, digestive endoscopic super minimally invasive surgery provided shorter operative times, less blood loss, and lower costs.
