ObjectiveTo summarize the progress and clinical application of portal vein embolization (PVE). MethodsDomestic and international publications about the PVE were retrieved and reviewed. ResultsPVE could effectively increase the perioperative security when selected at the appropriate time during liver resection surgery. However, there were some disputes on the best choice of the PVE in material, the use of dosage, and the clinical operation method. ConclusionsPVE as a method to induce liver to compensation, has a prominent role in increasing liver subtotal security, and improving the survival rate of patients. But it needs to be researched further to improve technique to promote future liver remnant hyperplasia compensatory faster and better.
ObjectiveTo summarize the application and the complications of pancreaticogastrostomy (PG) after pancreaticoduodenectomy(PD). MethodThe domestic and international publications involving the theory, methods, and clinical application of PG were retrieved and reviewed. ResultsPG was gradually concerned on the choice of the method of the digestive tract reconstruction after PD, in view of its advantages in theory and operation. The literatures about PG were increased in recent years. But the discussion of decreasing complications of PG after PD had yet to be unified. ConclusionsPG is one of the important operations of digestive tract reconstruction after PD. The factors of operator and patient should be comprehensively considered in the choice of PG.
ObjectiveTo investigate effect of sealing one-layer anastomosis in pancreaticojejunostomy in patients underwent pancreaticoduodenectomy. MethodsThe clinical data of 85 patients underwent pancreaticoduodenectomy in this hospital from January 2014 to May 2015 were collected. Of all the patients, 28 patients were underwent sealing onelayer anastomosis in pancreaticojejunostomy (sealing one-layer anastomosis group), 27 patients were underwent ductto-mucosa pancreaticojejunostomy (duct-to-mucosa anastomosis group), and 30 patients were underwent end-to-side invaginated pancreaticojejunostomy (end-to-side invagination group). The anastomosis time, time to pull out drainage tube, postoperative hospital stay, and incidence rate of postoperative pancreatic fistula were compared among these three groups. Results①The anastomosis time (min) of the sealing one-layer anastomosis group was significantly shorter than that of the duct-to-mucosa anastomosis group or end-to-side invagination group (12.51±2.96 versus 25.65±3.35, P < 0.05; 12.51±2.96 versus 23.73±5.27, P < 0.05).②The time to pull out drainage tube of the sealing one-layer anastomosis group was significantly shorter than that of the end-to-side invagination group (7.65±1.30 versus 11.15±3.47, P < 0.05).③The postoperative hospital stay had no statistical significances among these three groups (P > 0.05).④The incidence of pancreatic fistula was 3.57% (1/28), 7.41% (2/27), and 10.00% (3/30) among the sealing one-layer anastomosis group, duct-to-mucosa anastomosis group, and end-to-side invagination group respectively, which had no statistical differences among these three groups (P > 0.05). ConclusionSealing one-layer anastomosis in pancreaticojejunostomy might be a safe anastomosis, and it has advantages of simple operation and short operation time.
