title: Single-incision laparoscopic and endoscopic cooperative surgery for gastrointestinal stromal tumor arising from the duodenum.
abstract: We report a case involving a minimally invasive single-incision laparoscopic and endoscopic cooperative local excision of a duodenal gastrointestinal stromal tumor. A 59-year-old man presented with a 35-mm lesion located in the second portion of the duodenum. A local resection was performed via single-incision laparoscopic and endoscopic cooperative surgery. Intraluminal endoscopic dissection of the duodenal mucosa and submucosa was performed circumferentially around the tumor. The resection was then completed by laparoscopic dissection of the seromuscular layer around the tumor. The tumor was retrieved laparoscopically. After confirming that the resection achieved clear surgical margins, we closed the duodenal wall with a laparoscopic stapling device. There were no postoperative complications, including stenosis. Single-incision laparoscopic and endoscopic cooperative surgery can be safely and effectively performed for a duodenal submucosal tumor.
