Eating and drinking is a daily necessity for everyone, but in a very small percentage of people, food cannot enter the stomach smoothly because of a lesion in the muscle between the esophagus and the stomach, a condition called cardia achalasia, for which there was no particularly good treatment before. But happily, the Department of Gastroenterology of Drum Tower Hospital, affiliated with Nanjing University School of Medicine, recently successfully used a new technique, namely transoral endoscopic esophageal sphincterotomy, to treat cardia achalasia, and achieved very good results. The 58 year old Master Li, who has been eating poorly for more than 13 years, was diagnosed with pancreatic achalasia when he was sick for more than a year. He had endured the heartbreaking pain of balloon dilation and the long wait and torment of having a pancreatic stent placed, but it did not bring him sustained relief. Director Zou Xiaoping of the Department of Gastroenterology at Gulou Hospital arranged a transoral endoscopic esophageal sphincterotomy for Master Li, which lasted 45 minutes. There was no pain or other discomfort after the operation, and Master Li was able to get out of bed 3 hours after the operation and ate a bowl of noodles 12 hours after the operation.
