[Two Cases of Laparoscopic Partial Resection of Stomach Using a Trans-Gastric Wall Approach for Submucosal Tumors].

We performed laparoscopic partial resection of the stomach with a trans-gastric wall approach for submucosal tumors. Case 1: A 67-year-old woman was referred to our hospital because of tarry stool. Upper gastrointestinal endoscopy revealed a well demarcated, round, 45mm intraluminal-type submucosal tumor with delle on the anterior wall of the gastric upper body. Case 2: An 86-year-old woman was referred to our hospital because of anemia. Upper gastrointestinal endoscopy revealed a well demarcated, round, 25mm intraluminal-type submucosal tumor on the posterior wall of the gastric upper body. Laparoscopic partial resection of the stomach with a trans-gastric wall approach was performed. The operation times were 58 minutes and 73 minutes, respectively, and blood loss was low in both cases. This operative procedure is safe and easy and allows for resection resected with a direct view for surgeons without endoscopists.
