Description
Technical field
The present invention relates to medical operating articles for use technical field, belong to a kind of pancreas intestinal external drainage silica gel 3 pancreas intestinal ceca frame.
Background technology
It is complicated that tradition opens the operation of abdomen pancreaticoduodenectomy, operation wound is large, and biliary enteric anastomosis, Pancreaticoenterostomy are the committed steps of pancreaticoduodenectomy, because Cholangio-jejunostomy mouth or (with pancreas intestinal anastomotic stoma) Cholangio-jejunostomy mouth fistula, the Pancreaticojejunostomy entirely do not caused that heal is postoperative common severe complication, general incidence rate is 5 ~ 20%, Pancreaticojejunostomy mortality rate can reach 20 ~ 40%, and medical expense is expensive.
In recent years, domestic and international minority comprehensive large hospital peritoneoscope or the large case report of Leonardo da Vinci's robotic surgical device (Wicresoft) pancreaticoduodenectomy show, Wicresoft's pancreaticoduodenectomy opens abdomen pancreaticoduodenectomy than tradition, not only post-operative recovery is significantly accelerated, and postoperative short-term, long term survival rate are even better.But Wicresoft's advantage of peritoneoscope and Leonardo da Vinci robot pancreaticoduodenectomy, do not accepted extensively by outer scientific cirle, its main cause is peritoneoscope pancreaticoduodenectomy Cholangio-jejunostomy, the complexity of pancreas Surgical healing and technical difficulty, makes operating time significant prolongation; Our experience shows: especially as ductus pancreaticus diameter <3mm or marginality ductus pancreaticus, ductus pancreaticus is implemented very difficult to mucosa anastomosis under peritoneoscope, the probability of postoperative generation pancreas fistula significantly rises, pancreas Digestive system contact methods of anastomosis (as binding pancreas intestinal/pancreas stomach, pancreas intestinal side or end end, pancreas stomach embedding inosculating) have to be selected, thus increase the complication such as postoperative digestive tract hemorrhage; The technical bottleneck be difficult under although Leonardo da Vinci robot amplifies 10 times of surgical field of view by its three-dimensional and interior wrist breaches peritoneoscope flexibly, shorten the identical time, but, domestic only have 26 machines, and judgement that whether suture is definitely strained becomes very difficult during the disappearance of tactile feedback makes to coincide, tension can be broken suture or cut and organize, and crossing pine can cause fistula of operative incision, and reported literature also confirms peritoneoscope and robot postoperative pancreatic fistula, the incidence rate of leak does not significantly reduce.Therefore not only traditional pancreaticoduodenectomy biliary enteric anastomosis, Pancreaticoenterostomy remain a Research Challenges and focus, and in current Wicresoft, precisely, epoch of effective liver and gall pancreas surgery development, peritoneoscope and Leonardo da Vinci robot biliary enteric anastomosis, Pancreaticoenterostomy research and innovation are significantly more urgent.
