Chinese Journal of Digestive Surgery 2011;10(3):228-230
The combination of laparoscopy and gastroscopy makes up the defects of each of them when used alone, and further extends the application range of minimally invasive techniques. A 53-year-old patient with gastric stromal tumor was admitted to the Tenth People's Hospital of Tongji University on March 4, 2011. The result of gastroscopy showed that the tumor was at anterior wall of stomach with a size of 3.0 cm×3.5 cm. the result of CT scan preliminarily diagnosed the patient with gastric stromal tumor. Partial gastrectomy with laparoscopy combined with gastroscopy was applied to the patient on March 9, 2011. The operation time was 32 minutes and the blood loss was 10 ml. The duration of hospital stay was 4 days, and no postoperative complication occurred. Laparoscopy combined with gastroscopy for the treatment of gastric stromal tumor is feasible and safe with a favorable short-term outcome.

Dieulafoy lesion are usually located in the stomach but can also occur in the small or large intestines. It is an uncommon but significant source of massive upper gastrointestinal hemorrhage. A female patient with Dieulafoy lesion was admitted to the Tenth People's Hospital of Tongji University on June 2, 2009. The site of the lesion was diagnosed at the anterior wall of stomach with a bleeding vessel in the center. The size of the lesion was about 1.0 cm×1.0 cm. Partial gastric resection was successfully performed using laparoscopy and endoscopy. The lesion was demarcated by gastroscope, and then it was hung up and removed by laparoseope. Bowel movement recovered at the second day, and the patient was discharged 6 days after surgery. The patient was followed up for 1 month, and no recurrent hemorrhage or other complications were observed. The combined approach of laparoscopy and endoscopy not only resects the lesion completely and widens the scope of minimally invasive surgery but also decreases the risk of operation.
