The patient was a young male with acute pancreatitis induced by alcohol abuse, who had unsatisfactory results after 2 weeks of conservative treatment, with significant abdominal distension and pain. CT examination indicated a large retroperitoneal effusion and a blurred pancreatic pattern with unclear borders. Based on careful analysis of the case, Dr. Kang Junsheng, director of general surgery, decided to operate on the patient using a retroperitoneal approach with laparoscopic technique. In collaboration with the deputy director of urology, Zhou Feng, and with the strong cooperation of the anesthesiology department and the operating room, the operation was successfully completed, taking about 2 hours, and 1000 ml of pus was drained during the operation. And the patient was left with only 3 small openings about 1 cm long in the waist. The postoperative recheck CT indicated that the retroperitoneal fluid was significantly reduced. The blood routine returned to normal, the body temperature was normal, and he had already eaten normally. After more than 40 days of hospitalization, he was discharged from the hospital. The director of the hospital introduced that acute pancreatitis is a common acute and critical clinical disease, with a mortality rate of up to 50%. The early stage can be a large amount of exudate, necrosis of the pancreas and peripancreatic tissue, serious infection and difficult to control. Therefore, timely and effective drainage of peripancreatic exudate, reduction of pancreatic and peripancreatic exudate and tissue necrosis, and control of infection can effectively improve the prognosis. Traditional open surgery is more traumatic, has obvious impact on the abdominal viscera, and has poor drainage and serious postoperative abdominal adhesions. The non-surgical treatment for severe pancreatitis is not ideal. The recently developed laparoscopic surgery via the abdominal approach is less traumatic, but the microscopic operation is complicated and the drainage is not adequate. The method adopted by the hospital is more reasonable from anatomical analysis, with more direct surgical access, complete removal of necrotic material and adequate drainage. In addition, since it does not enter the abdominal cavity, it has almost no effect on the abdominal organs and does not leave abdominal adhesions, nor does it bring necrotic infected tissue into the abdominal cavity, greatly reducing the possibility of abdominal infection. Patients have light postoperative pain, quick recovery, and high satisfaction with the cosmetic incision. Finally, experts remind us that the common causes of acute pancreatitis are improper diet, overeating, especially eating greasy food, drinking alcohol, some statistics about 20% to 60% of acute pancreatitis occurs after overeating. In addition, if the original suffer from gallstone disease, biliary ascariasis, cholecystitis, pancreatic stone and other diseases that cause poor bile-pancreatic fluid excretion, then after overeating is more likely to induce pancreatitis. The key to pancreatitis prevention is to keep your mouth shut, drink and socialize in moderation, and eat more high-fiber vegetables to enhance gastric power. Usually, after an acute attack of pancreatitis, it is forbidden to eat fatty foods for two weeks to a month, and then gradually resume a normal diet. It is best for patients who have had pancreatitis to give up smoking and alcohol for life to prevent further attacks.
