Laparoscopic wedge resection is now widely performed for extraluminal gastric gastrointestinal stromal tumors (gGIST). However, this method for intraluminal gGIST may cause inadvertent resection of gastric tissue and lead to gastric cavity deformation. Herein, we introduce a technique of laparoscopic wedge resection with seromyotomy to achieve maximum preservation of remnant stomach volume for intraluminal gastric gastrointestinal stromal tumors. First step was exploring the abdominal cavity and indentify the tumor location. A cut line around the tumor was established with an adequate surgical margin by using an electric coagulation rod. Then the seromuscular layer was dissected with the intraluminal gGIST turned to be an extraluminal tumor. Laparoscopic wedge resection could be easily performed with maximum preservation of remnant stomach volume. Finally, the gastric incision was strengthened with laparoscopic continuous suture technique. Laparoscopic wedge resection with seromyotomy can achieve maximum preservation of remnant stomach volume for intraluminal gGIST.
