Description
Technical Field
The invention relates to the technical field of medical instruments for operations, in particular to a stent drainage tube applied to pancreaticojejunostomy.
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 was reduced 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 the pancreas duodenectomy is 20-40%. Once pancreatic fistula occurs, a series of serious consequences such as hydrops in abdominal cavity, abdominal cavity infection, delayed gastric emptying, hemorrhage after pancreas operation and the like can be caused, deep research on pancreatic fistula after pancreatic duodenectomy can be helpful to reduce the incidence rate of the pancreatic fistula, and in order to reduce the incidence rate of pancreatic fistula complications after pancreatic duodenectomy, people make a lot of beneficial exploration and innovation. In the reconstruction mode of pancreas and digestive tract, two types of operation modes of pancreaticogastrostomy and pancreaticoenteroanastomosis are generated, the former has no obvious superiority, and the latter is mainly used in the current clinical application. In various pancreaticostomies, two main types are classified into pancreaticoenterostomy and catheter-to-mucosa anastomosis. Wherein the nested type anastomosis means that the broken end of pancreas is integrally nested into jejunum, single-layer or double-layer suture is carried out, and because a main pancreatic duct does not need to be searched for anastomosis, the nested type anastomosis technology is simple, convenient and easy to learn, has certain advantages for patients with thin pancreatic ducts, and has the following representative nested type pancreaticojejunostomy: peng shu you, "tie-in fit", Chen Shi U-shaped fit-in stitch of Chenxiao Ping Shi, Blumgart pancreas-intestine fit and various modified Blumgart pancreas-intestine fit; and the pipe coincide the mucosa and need sew up main pancreatic duct and jejunum wall full-thickness, and the operation is meticulous, and the patient operation degree of difficulty that is thinner to the pancreatic duct is great, nevertheless accords with the physiology characteristics of pancreas drainage more, has avoided the exposure of whole section in the intestinal digestive juice, and representative pipe has to the mucooperation formula: the pancreatico anastomosis mode of mucous membrane by the 'soldier' type (R8) catheter of the professor Peng Dynasty, the 'one-needle pancreatico enteroanastomosis' of Hongdefei and the like. There is also a great deal of research on the comparison of the two approaches, but there is still some controversy about their merits.
In summary, no matter the laparotomy or the laparoscopic surgery, the current pancreatic duct has certain operation difficulty for anastomosis of the jejunal mucosa, and the pancreaticotomy is a key step of the pancreaticoduodenectomy, so that various currently clinically applied pancreaticointestinostomy techniques inevitably have complications of postoperative pancreatic fistula, serious pancreatic fistula can be fatal, and meanwhile, various currently clinically applied pancreaticointestinostomy techniques have the defect of complex operation.
