Filter by:Pancreaticoduodenectomy (PD) is the standard treatment for tumors of the pancreatic head, distal bile duct, duodenum, and ampulla of Vater. With advances in surgical experience and instrumentation, the mortality rate of PD has decreased to below 5% in high-volume pancreatic centers. However, the postoperative complication rate remains high at 25%-50%, limiting the development and application of PD. The main postoperative complications of PD are postoperative pancreatic fistula (POPF), delayed gastric emptying (DGE), post-pancreatectomy hemorrhage (PPH), and biliary leakage (BL). POPF, BL, and the subsequent abdominal infection, PPH, etc. are the main causes of death during hospitalization. Even in large, relatively mature pancreatic centers, the incidence of POPF remains as high as 10%-40%. In recent years, various methods have been used to prevent and treat POPF and BL after PD, such as pancreatic duct stent external drainage and external biliary drainage. To date, there have been many studies by domestic and foreign scholars on the advantages and disadvantages of biliary and pancreatic duct external drainage versus internal drainage in PD in terms of perioperative POPF incidence, mortality rate, etc., but the research results are not consistent. Overall, pancreatic duct stent external drainage is only recommended for patients with a high risk of pancreatic fistula during PD. Currently, there have been a few relevant studies exploring and verifying the preventive effect of pancreatic duct stent external drainage on pancreatic fistula in patients with high risk of pancreatic fistula. For example, a retrospective study of 98 patients with soft pancreatic parenchyma by Teruyuki Usub et al. found that there was no significant difference between groups with and without pancreatic duct stent in preventing pancreatic fistula. However, due to the low level of evidence, only a few risk factors such as pancreatic texture and pancreatic duct diameter were included, and the risk of POPF was not systematically evaluated. Further clinical exploration and verification are needed. In 2013, Mark P Callery et al. proposed a pancreatic fistula risk score (The fistula risk score, FRS) based on the pancreatic fistula standard defined by the International Pancreatic Fistula Study Group, which included pancreatic texture, pathological type, pancreatic duct diameter, and intraoperative blood loss. This model can be used to systematically and quantitatively evaluate the risk of POPF. Previous studies did not have a clear stratification for patients undergoing pancreatic duct stent external drainage, which may have included too many patients with a low risk of pancreatic fistula, resulting in inaccurate results. Therefore, it is necessary to re-evaluate the effectiveness of pancreatic duct stent external drainage in preventing clinically relevant pancreatic fistula based on stratification of pancreatic fistula risk and disease type. At the same time, pancreatic juice contains a variety of digestive enzymes, of which pancreatic lipase, trypsin, and chymotrypsin all need to be activated by bile to play a role in digesting and decomposing fat and protein. Theoretically, biliary and pancreatic juice diversion may be able to reduce the incidence of pancreatic fistula and its related complications in PD patients. Thus, the investigators design the present study to evaluate the impact of main pancreatic duct and biliary duct external drainage on postoperative complication, especially POPF.
The main objective of the study is to compare 2 broad-spectrum antibiotic (Piperacillin / Tazobactam) treatment modalities, following pancreaticoduodenectomy in patients with preoperative biliary stent, to demonstrate the superiority of a 5-day post-operative antibiotic therapy to antibiotic prophylaxis on the occurrence of surgical site infections (SSI)
A comprehensive perioperative nutrition management plan for pancreaticoduodenectomy, primarily based on pancreatic enzyme replacement therapy (PERT). A prospective randomized controlled study was conducted to comprehensively analyze the perioperative nutritional status of patients undergoing pancreaticoduodenectomy, with the aim of exploring: 1. The effect of PERT on postoperative complications and physiological status after pancreaticoduodenectomy; 2. The efficacy of PERT treatment on clinical symptoms, nutritional indicators, and quality of life (QOL) related to pancreatic exocrine dysfunction (PEI) after pancreaticoduodenectomy; 3. The personalized full process nutrition management strategies based on risk factor stratification.
A few reports were focused on the RPD learning curve for surgeons with extensive experience in LPD. Therefore, this study aimed to investigate the number of cases required for such surgeons to overcome the learning curve for RPD and to analyze the impact of different phases of the learning curve on perioperative outcomes.
The purpose of this study is to compare intra and postoperative pain control between Paravertebral block vs no block in open pancreaticoduodenectomy. Length of stay, and complications will also be recorded. For this study the investigator plans to randomize to obtain objective data for clinical decisions and improve patient outcomes. Following surgery patients in both groups, data will be collected from the first 48 hours after surgery and at discharge.
The purpose of this clinical trial is to test whether electrical stimulation of the vagus nerve via a device placed on the top of the external ear can reduce the postoperative inflammatory reaction after Whipple's surgery (pancreatoduodenectomy).
This prospective validation study aims to investigate the incidence of PPAP after pancreaticoduodenectomy (PD) by applying the ISGPS definition and grading system, to demonstrate its clinical impact by examining associated postoperative outcomes, and to validate its applicability through an economic assessment.
Preoperative biliary drainage predisposes the bile to be contaminated with bacteria of the duodenum. These bacteria colonizing the bile are a potential source for surgical site infections after pancreaticoduodenectomy and many international guidelines recommend the use of cephalosporines as microbial prophylaxis before surgery. The aim of this study was to assess the incidence of bacteria in bile, their resistance profiles and association to surgical site infections in relation to timing of surgery after preoperative biliary drainage in order to better guide antibiotic use.
The primary objective of this clinical trial is evaluate the effect of dexamethasone on postoperative complications after pancreaticoduodenectomy.
More than 8 millions surgical interventions are carried out each year in France. Postoperative complications, in particular infectious, can occur in 10 to 60% of cases and are the cause of postoperative revision in 30% of cases, an increase in mortality, length of stay, readmissions and lead to significant additional socio-economic costs. Currently, improvements in surgical practices have not reduced the incidence of surgical site complications. In this context, the development of predictive scores for the risk of post-operative complication becomes urgent in order to implement new interventions (pre-habilitation) or to modify surgical decisions (timing, approach) in order to reduce the risk of complications before surgery. Several recent studies highlights the importance of the immune response in postoperative prognosis. In particular, an imbalance between the adaptive and innate response involving MDSCs has been demonstrated in patients with postoperative complications.Thanks to new techniques for analyzing the immune system, in-depth analysis of the immune system before surgery is a very promising approach aimed at identifying predictive biomarkers of postoperative prognosis. Our team has developed and patented a multivariate model integrating mass cytometry data, proteomics and clinical data collected before surgery to accurately predict the occurrence of a surgical site complication (AUC = 0.94, p<10e-7) in a monocentric cohort of 43 patients to major abdominal surgery (Stanford University). The objective of the present study is to generalize and validate this preoperative predictive score of infectious complications of the surgical site in the 30 days following major digestive surgery on a larger workforce within a multicenter cohort and to validate this score at using a machine learning method.
