Figure 8 Comparison of surgical margins between laparoscopic and endoscopic cooperative surgery and conventional wedge resection. A: Specimen of Laparoscopic and endoscopic cooperative surgery (LECS). The surgical margin from the tumor is kept at the proper distance; B: Specimen of conventional wedge resection. Simple wedge resection causes both excessive and inadequate resection of the gastric wall, which may lead to postoperative gastric stenosis, gastric dysfunction, and local recurrence; C and D: Intraoperative view of conventional wedge resection with a linear stapler. The resection line is as shown in Figure 1B. The specimen has a portion too close to the tumor and a portion far from the tumor.
