DGE represents impaired gastric motility without significant mechanical obstruction and is associated with an increased length of hospital stay, increased healthcare costs, and a high readmission rate. We reviewed published studies on various technical modifications to reduce the incidence of DGE. Data sources: Studies were identified by searching Pub Med for relevant articles published up to December 2022. The following search terms were used: “pancreaticoduodenectomy”, “pancreaticojejunostomy”, “pancreaticogastrostomy”, “gastric emptying”, “gastroparesis” and “postoperative complications”. The search was limited to English publications. Additional articles were identified by a manual search of references from key articles. Results: In recent years, various surgical procedures and techniques have been explored to reduce the incidence of DGE. Pyloric resection, Billroth II reconstruction, Braun's enteroenterostomy, and antecolic reconstruction may be associated with a decreased incidence of DGE, but more high-powered studies are needed in the future. Neither laparoscopic nor robotic surgery has demonstrated superiority in preventing DGE, and the use of staplers is controversial regarding whether they can reduce the incidence of DGE. Conclusions: Despite many innovations in surgical techniques, there is no surgical procedure that is superior to others to reduce DGE. Further larger prospective randomized studies are needed.展开更多

Postoperative pancreatic fistula(POPF) was defined and classified by the international study group of pancreatic fistula(ISGPF).We used a logistic regression model to determine the independent risk factors of CR-POPF and developed a scoring system based on the regression coefficient of the logistic regression model. The optimal cut-off value to divide the risk strata was determined by the Youden index. The patients were divided into two groups(low risk and high risk). The independent sample t test was used to detect differences in the means of drain amylase on postoperative day(POD) 1, 2 and 3. The optimal cut-off level of the drain amylase to distinguish CR-POPF from non-clinical POPF in the two risk strata groups was determined using the receiver operating characteristic(ROC) curves.RESULTS: Grade A POPF occurred in 106(11.5%)patients, grade B occurred in 57(6.2%) patients,and grade C occurred in 32(3.5%) patients. A predictive scoring system for CR-POPF(0-6 points) was constructed using the following four factors: 1 point for each body mass index ≥ 28 [odds ratio(OR) = 3.86;95% confidence interval(CI): 1.92-7.75, P = 0.00],soft gland texture(OR = 4.50; 95%CI, 2.53-7.98, P =0.00), and the difference between the blood loss and transfusion in operation ≥ 800 mL(OR = 3.45; 95%CI,1.92-7.75, P = 0.00); and from 0 points for a 5 mm or greater duct diameter to 3 points for a less than 2 mm duct(OR = 8.97; 95%CI: 3.70-21.77, P = 0.00). The ROC curve showed that the area under the curve of this score was 0.812. A score of 3 points was suggested to be the best cut-off value(Youden index = 0.485). In the low risk group, a drain amylase level ≥ 3600 U/L on POD3 could distinguish CR-POPF from non-clinicalPOPF(the sensitivity and specificity were 75% and85%, respectively). In the high risk group, the best cutoff was a drain amylase level of 1600(the sensitivity and specificity were 77 and 63%, respectively).CONCLUSION: A 6-point scoring system accurately predicted the occurrence of CR-POPF. In addition, a drain amylase level on POD3 might be a predictor of this complication.展开更多

AIM To construct a new risk scoring system for CR-POPF that includes both preoperative and intraoperative factors. METHODS This was a retrospective study of patients who underwent pancreaticoduodenectomy (PD) or pylorus-preserving PD (PPPD) between January 2011 and December 2016 at the First Affiliated Hospital of Soochow University. Patients were divided into a study (01/2011 to 12/2014) or validation (01/2015 to 12/2016) group according to the time of admission. POPF severity was classified into three grades: Biochemical leak (grade A) and CR-POPF (grades B and C). Logistic regression was used to create a predictive scoring system. RESULTS Preoperative serum albumin ≥ 35 g/L [P = 0.032, odds ratio (OR)= 0.92, 95% confidence interval (CI): 0.85-0.99], hard pancreatic texture (P = 0.004, OR = 0.25, 95%CI: 0.10-0.64), pancreatic duct diameter ≥ 3 mm (P = 0.029, OR = 0.50, 95%CI: 0.27-0.93), and intraoperative blood loss ≥ 500 mL (P = 0.006, OR = 1.002, 95%CI:1.001-1.003) were independently associated with CR-POPF. We established a 10-point risk scoring system to predict CR-POPF. The area under the curve was 0.821 (95%CI: 0.736-0.905) and the cut-off value was 3.5. Including drain amylase levels improved the predictive power of the model. CONCLUSION This study established a 10-point scoring system to predict CR-POPF after PD/PPPD using preoperative and intraoperative parameters. Ultimately, this system could be used to distinguish between high- and low-risk populations in order to facilitate timely interventions after PD.展开更多

Patients were divided into two groups depending on postoperative nutrition support scheme: an EEN + PN group (n = 87) and a TPN group (n = 253). Demographic characteristics, comorbidities, preoperative biochemical parameters, pathological diagnosis, intraoperative information, and postoperative complications of the two groups were analyzed.RESULTS: The two groups did not differ in demographic characteristics, preoperative comorbidities, preoperative biochemical parameters or pathological findings (P > 0.05 for all). However, patients with EEN + PN following PD had a higher incidence of delayed gastric emptying (16.1% vs 6.7%, P = 0.016), pulmonary infection (10.3% vs 3.6%, P = 0.024), and probably intraperitoneal infection (18.4% vs 10.3%, P = 0.059), which might account for their longer nasogastric tube retention time (9 d vs 5 d, P = 0.006), postoperative hospital stay (25 d vs 20 d, P = 0.055) and higher hospitalization expenses (USD10397 vs USD8663.9, P = 0.008), compared to those with TPN.CONCLUSION: Our study suggests that TPN might be safe and sufficient for patient recovery after PD. Postoperative EEN should only be performed scrupulously and selectively.展开更多

Pancreaticoduodenectomy, one type of pancreatic resection, is a complex surgery with the loss of pancreatic integrity and various anastomoses. Complications after pancreaticoduodenectomy such as pancreatic fistulas and anastomosis leakage are common and significantly associated with patient outcomes. Pancreatic fistula is one of the most important postoperative complications; this condition can cause intraperitoneal hemorrhage, septic shock, or even death. An effective way has not yet been found to avoid the occurrence of pancreatic fistula. In most medical centers, the frequency of pancreatic fistula has remained between 9% and 13%. The early detection and routine drainage of anastomotic fistulas, pancreatic fistulas, bleeding, or other intra-abdominal fluid collections after pancreatic resections are considered as important and effective ways to reduce postoperative complications and the mortality rate. However, many recent studies have argued that routine drainage after abdominal operations, including pancreaticoduodenectomies, does not affect the incidence of postoperative complications. Although inserting drains after pancreatic resectionscontinues to be a routine procedure, its necessity remains controversial. This article reviews studies of the advantages and disadvantages of routine drainage after pancreaticoduodenectomy and discusses the necessity of this procedure.展开更多

文摘BACKGROUND The influence of bile contamination on the infectious complications of patients undergoing pancreaticoduodenectomy(PD)has not been thoroughly evaluated.AIM To evaluate the effect of preoperative biliary drainage and bile contamination on the outcomes of patients who undergo PD.METHODS The database of 4101 patients who underwent PD was reviewed.Preoperative biliary drainage was performed in 1964 patients(47.9%),and bile contamination was confirmed in 606 patients(14.8%).RESULTS The incidence of postoperative infectious complications was 37.9%in patients with preoperative biliary drainage and 42.4%in patients with biliary contamination,respectively.Patients with extrahepatic bile duct carcinoma,ampulla of Vater carcinoma,and pancreatic carcinoma had a high frequency of preoperative biliary drainage(82.9%,54.6%,and 50.8%)and bile contamination(34.3%,26.2%,and 20.2%).Bile contamination was associated with postoperative pancreatic fistula(POPF)Grade B/C,wound infection,and catheter infection.A multivariate logistic regression analysis revealed that biliary contamination(odds ratio 1.33,P=0.027)was the independent risk factor for POPF Grade B/C.The three most commonly cultured microorganisms from bile(Enterococcus,Klebsiella,and Enterobacter)were identical to those isolated from organ spaces.CONCLUSION In patients undergoing PD,bile contamination is related to postoperative infectious complication including POPF Grade B/C.The management of biliary contamination should be standardised for patients who require preoperative biliary drainage for PD,as the main microorganisms are identical in both organ spaces and bile.
