Pancreatic pseudocysts are secondary to acute and chronic pancreatitis and pancreatic injury, with complications such as bleeding, infection and obstruction. For example, after the recovery from acute pancreatitis, especially severe pancreatitis, review of CT or abdominal ultrasound found that there is a large cyst in the epigastric region, when the cyst is larger than 6cm, time is greater than 6 weeks without significant reduction, often it is necessary to treat. Because if not treated, there are complications such as cyst infection, cyst rupture and intracystic hemorrhage, and at this time, the symptoms may only be epigastric discomfort or epigastric distension, or in severe cases, there are nausea and vomiting, fever and other symptoms. At present, the treatment of pancreatic pseudocysts is mainly effective internal drainage. With the development of minimally invasive technology, endoscopy and laparoscopy have become the main methods of treating pancreatic pseudocysts. Both endoscopic treatment of pancreatic pseudocysts and laparoscopic treatment of pancreatic pseudocysts have the advantages of being minimally invasive, esthetic, and fast postoperative recovery. Endoscopic treatment only requires puncture and tube placement under gastroscope, no incision on the abdominal wall, and you can eat and get out of bed the next day after the operation. Laparoscopic treatment only requires a few small holes on the abdominal wall to complete the operation, and the postoperative recovery is also very fast, which is better than the traditional open surgery, less traumatic and quicker recovery.
