Modified vs Conventional Blumgart Anastomosis of LPD for the Effects of Pancreatic Fistula of Periampullary Carcinoma

Pancreas Cancer Clinical Trial

Official title: Modified Blumgart vs Conventional Blumgart Anastomosis Technique in the Treatment of Periampulltrary Carcinoma on Postoperative Pancreatic Fistula: an Open, Randomized, Parallel Controlled Clinical Study

Status Enrolling by invitation

Clinical Trial Summary

The incidence rate and mortality rate of periampullary cancer at home and abroad both show an increasing trend, seriously affecting the health level of the people. Pancrecoduodenectomy (PD) is the only effective treatment for periampullary cancer. However, due to the complex technology and difficulty of PD surgery, laparoscopic pancreaticoduodenectomy (LPD) is more difficult, and the postoperative mortality can reach 5%. The important reason is the most serious complication- -pancreatic fistula. The occurrence of pancreatic fistula is related to many factors, and the most critical factor is the method and technology of pancreatico-intestinal anastomosis, so the improvement and innovation of pancreaticoco-intestinal anastomosis technology has always been a hot topic in surgical clinical research. Blumgart Pancreatic anastomosis was originally created by Professor L.H.Blumgart in the United States, and was widely used in OPD due to its low incidence of pancreatic fistula. However, the traditional Blumgart anastomosis is complicated and is not suitable for application in LPD. According to our own experience, our team simplified and improved the traditional Blumgart anastomosis to OPD, and through retrospective study, it has the advantages of reducing the incidence of pancreatic fistula. However, the application value in LPD still needs to be further discussed. Therefore, this study intends to use a prospective randomized controlled trial, using the LPD patients with traditional Blumgart pancreatecointestinal anastomosis as the control group, and the LPD patients with modified Blumgart pancreatecointestinal anastomosis as the test group, compare the clinical relevant indicators and the incidence of postoperative complications, and explore whether the application value in LPD can truly simplify the surgical procedure and ensure the lower incidence of pancreatic leakage.

Clinical Trial Description

This study intends to use a prospective randomized controlled trial, the LPD patients with traditional Blumgart anastomosis as the control group, design the LPD patients with modified Blumgart anastomosis as the test group, by comparing the clinical correlation index and the rate of postoperative complications in LPD can truly simplify the surgical procedure and ensure the lower rate of pancreatic leakage. The following steps will be followed: 1. Patients who met the inclusion criteria and did not meet the exclusion criteria underwent modified Blumgart anastomosis according to the randomization LPD surgery group (test group) or LPD surgery group with conventional Blumgart pancreatecreenterostomy (control group). 2. The following common LPD procedure was used in the test and control groups: ① Preoperative preparation and anesthesia mode Preoperative gastric tube, urinary tube and central venous channel; general anesthesia ② Same surgical procedure: Establishment of artificial pneumoperitoneum and operating hole anatomical exploratory specimen resection and reconstruction of digestive tract (biliary intestine kiss Combination, gastrointestinal anastomosis) drain placement. 3. In the test group, the pancreatic intestine anastomosis in the LPD Combined, the control group used conventional Blumgart pancreatestatic anastomosis. 4. Both postoperative groups were routinely given anti-infection, gastric mucosa protection, somatostatin, and nutritional supportive therapy. After the first Remove gastric tube and urinary catheter on 3 days, instructed patients to eat cold liquid food and ambulation; somatostatin was stopped on postoperative day 5, The upper abdominal CTA was reviewed, and the remaining treatment plans were formulated according to the actual situation of the patient. Postoperative numbers 1,3,5, and For 7 days, the relevant drainage indexes, daily drainage rate, drainage properties and amylase content were reviewed. 5. If the patient can be discharged with the following conditions: the general condition is good, and the normal diet and intestinal function are basically restored; Body temperature was normal and the abdominal examination showed no positive signs; relevant laboratory results were almost normal; CTA Significant abdominal effusion and other abnormalities; postoperative abdominal incision healed well. 6. After discharge, pay attention to their appetite, spirit, urine and feces, and drainage tube (discharged with drainage tube). Patients without special discomfort were returned to the hospital for review once at 1and 3 months after surgery. ;
