Bezoars of the gastrointestinal tract are a relatively rare disorder that affects the gastrointestinal system. The currently available treatment methods for a gastric phytobezoar include dissolution of the bezoar by Coca-Cola®, removal by endoscopic devices, laparotomy and laparoscopic surgery. We report here the case of a 52-year-old woman, suffering from upper epigastric pain due to gastric bezoar and pyloric obstruction that required surgery. 3D laparoscopic surgery was performed. Two months after the surgery, she was asymptomatic and recovered. The pathological examination suggested that it was fibrous bezoar. 3D laparoscopy was suggested to be an effective method in treating gastric bezoar.
