Abstract
The patient was a 73-year-old woman in whom an elevated lesion in the gastric cardia was pointed out 1 year prior. Biopsy of the lesion showed that it had increased in size and revealed a neuroendocrine tumor (NET). Upper gastrointestinal endoscopy showed that the lesion was 7 mm in diameter. The patient underwent laparoscopy and endoscopy cooperative surgery (LECS) for lesion resection. We used a clip laparoscopically at the serosal site of the lesion and made artificial perforations endoscopically with the needle knife around the lesion. The cut line was determined by the position of the clip and perforations. All layers of the gastric wall were laparoscopically dissected using an ultrasonically activated device. The incision line was closed using a laparoscopic stapling device under endoscopic observation to protect the esophagogastric junction. Surgical margins were negative on histopathological examination. Postoperative fluoroscopy showed no stenosis in the stomach. Here we report our experience with successful cooperative laparoscopy and endoscopy surgery for NET resection in the gastric cardia.
