Description
Technical Field
The utility model belongs to the technical field of medical appliances, concretely relates to medical leak protection type pancreas intestines supports drainage tube that coincide.
Background
Pancreaticojejunostomy is the anastomosis of the remaining pancreas and jejunum, an essential step in the reconstruction of the digestive tract from a pancreatoduodenectomy. By the 90 s of the 20 th century, the operative mortality rate of pancreatoduodenal resection has decreased to below 5%, thus becoming the current standard for the treatment of periampulla tumors, head tumors and other small portions of benign pancreatic diseases. It is worth mentioning that although the death rate of the pancreas duodenectomy in the operative period is continuously reduced, the complication rate is always high, and the most important part is the pancreas fistula after the operation. The incidence rate of pancreatic fistula after pancreatic duodenectomy is 20-40%, once pancreatic fistula occurs, a series of serious consequences such as peritoneal effusion, abdominal infection, delayed gastric emptying, and hemorrhage after pancreatic surgery can be caused, and the deep research on pancreatic fistula after pancreatic duodenectomy can be helpful to reduce the incidence rate of pancreatic fistula.
In surgical operation, if the broken end of pancreas and jejunum need to be anastomosed, a supporting tube with the diameter similar to that of the pancreatic duct is usually placed in the middle of the anastomotic stoma in advance, the supporting tube crosses the anastomotic stoma, one end with a drainage side hole is in the pancreas, and the other end is in the intestinal duct. After placement of the support tube, the pancreas and intestine were anastomosed. The pancreas intestine anastomosis supporting tube has the effects that an anastomosis opening can be supported within a certain time, the pancreas tube is prevented from being blocked due to collapse of the anastomosis opening, pancreas liquid is drained at the same time, and the pancreas liquid is drained into the intestine tube through the supporting tube. The abnormal anastomotic drainage is not smooth and pancreatic juice leaks, which are common complications of the pancreatic surgery, the occurrence of the complications obviously prolongs the hospitalization time, the early rehabilitation of patients is not facilitated, serious patients even need to perform the operation again, and the potential huge risk is brought to the patients. Because the anatomical structures of different people are not completely the same, the traditional supporting tube is difficult to completely fit the size of the pancreatico anastomotic stoma, and the pancreatic duct is easily damaged due to the fact that the supporting tube is too thick, so that the post-operation pancreatitis is caused; if the supporting tube is too thin, the supporting and drainage effects are poor, and pancreatic juice is easy to leak; if the supporting tube is not firmly fixed, the supporting tube of the pancreatico-intestinal anastomotic stoma is easy to slip.
