case_images: Chest radiography indicated mirror dextrocardia [Figure 1a]. Gastrointestinal barium fluoroscopy [Figure 1b] revealed the following: (1) SIT and (2) potential space-occupying lesion in the gastric antrum. Chest + whole abdomen contrast-enhanced computed tomography (CT) [Figure 1c] showed the following: (1) SIT; (2) irregularly thickened gastric wall of the antrum, with the possibility of gastric antral carcinoma and (3) slightly larger lymph nodes (LNs) in the hepatogastric space.

case_images: Intraoperative laparoscopy revealed the following: the liver and gall bladder were located in the left upper abdomen, the spleen was located in the upper right abdomen, the greater curvature of the stomach fundus was located on the right side and the pylorus and duodenum were located on the left side [Figure 3a]. Based on membranous anatomy, 3D laparoscopy-assisted radical gastrectomy by the 'enjoyable space' approach was employed to achieve complete tumour resection + D2 LN dissection. (1) Using the 'pick up and separate method' to dissect the lower pyloric region [Figure 3b], the surgeon used blunt separations to enter the gastrocolic fusional fascial space and then dissected the anterior fascia of the head of pancreas along the anterior pancreatic head and separated the right gastroepiploic vein. From the lower edge to the upper edge of the pancreatic neck, the root of the right gastroepiploic artery was disconnected to achieve LN dissection in the lower pyloric region. (2) Using the 'Tent method' to separate the left area of the celiac trunk [Figure 3c], the surgeon dissected the anterior pancreatic fascia and the mesangial lobe of the hepatoduodenal ligament to reach the common bile duct leftward. The coronary vein was exposed and disconnected. (3) Using the 'enjoyable space separation method' to separate the right area of the celiac trunk [Figure 3d], the surgeon made an incision at the junction of the left gastric artery and splenic artery, entered into the fusional fascial space between the gastric dorsal mesangium and retroperitoneum (i.e., the 'enjoyable space').
