Consecutive patients were enrolled and were divided into Group 1(the formation time of phytobezoars was less than 7 days), Group 2(the formation time of phytobezoars was from 7 days to 14 days) and Group 3 (the formation time of phytobezoars was more than 14 days) according to the formation time of phytobezoars and each group was subdivided into control group (who refused to diet Coca-Cola and chose emergent fragmentation with gastroscopy) and intervention Group (who had a willing to diet Coca-Cola) from 1st Jan, 2017 to 1st Dec 2021.
