ObjectiveTo explore effect of preoperative prognostic nutritional index (PNI) on clinically related postoperative pancreatic fistula (CR-POPF) after distal pancreatectomy (DP) and analyze its influencing factors in order to provide a basis for clinical prediction of CR-POPF. MethodsThe clinicopathologic data of patients who successfully completed DP in the Affiliated Hospital of Xuzhou Medical University and met the inclusion and exclusion criteria of this study from January 1, 2017 to January 31, 2021 were collected retrospectively. The preoperative PNI value was calculated and the optimal cut-off value was obtained according to the receiver operative characteristic (ROC) curve. The patients were divided into low and high PNI based on the optimal cut-off value. The clinicopathologic characteristics were compared between the patients with low and high PNI and CR-POPF or not. At the same time, multivariate logistic regression was used to analyze the influencing factors of CR-POPF. ResultsA total of 143 patients who met the inclusion and exclusion criteria were included in this study. The CR-POPF occurred in 33 cases (23.08%) after DP, and the average preoperative PNI was 52.26 (39.20–65.10), the optimal cut-off value of PNI was 50.55, with 49 cases in the low PNI group and 94 cases in the high PNI group. In patient with low PNI, the proportions of patients aged ≥65 years and with CR-POPF were higher than those with high PNI (P<0.05). In the patients with CR-POPF, the proportions of patients with soft pancreatic texture and with low preoperative PIN were higher than those without CR-POPF (P<0.05). Further, the multivariate logistic regression showed that the the preoperative low PNI (OR=5.417, P<0.001) and soft pancreatic texture (OR=4.126, P=0.002) increased the risk of CR-POPF. ConclusionLow preoperative PNI and soft pancreatic texture increase risk of CR-POPF after DP, and it is necessary to preoperatively evaluate PNI status of patients.
Objective To analyze the risk factors of postoperative pancreatic fistula (POPF) after distal pancreatectomy (DP) and to explore the effective index of predicting POPF after DP. Methods The clinical data of 120 patients with pancreatic disease who were treated with DP in the Department of Tumor Surgery of Xuzhou Medical University from January 2010 to November 2017 were analyzed retrospectively. The influencing factors of POPF after DP were analyzed by non-conditional logistic regression. Results Of the 120 patients, 15 patients (12.5%) had clinically significant POPF, including 13 cases of grade B pancreatic fistula and 2 cases of grade C pancreatic fistula. The results of non-conditional logistic regression showed that, the soft pancreas and preoperative pancreatic CT value of the pancreas less than 40 Hu were the independent risk factors of POPF after DP (P<0.05). Conclusions Pancreatic texture and preoperative CT value are important factors influencing the occurrence of POPF after DP. Evaluating the preoperative CT value and intraoperative pancreatic texture can effectively predict the risk of POPF after DP.
ObjectiveTo investigate the factors that affect the occurrence of postoperative pancreatic fistula (POPF) after distal pancreatectomy (DP).MethodsThe clinical data of 114 patients underwent DP who were performed in the First Affiliated Hospital of Xinjiang Medical University from Jan. 2014 to Jun. 2019, were retrospectively analyzed.ResultsIn this group of 114 patients, 43 cases (37.7%) of POPF occurred after DP, including 19 cases of grade A (biochemical fistula), 21 cases of grade B, and 3 cases of grade C. The univariate analysis results showed that: BMI value, drinking history, preoperative plasma albumin level, postoperative plasma albumin level, postoperative neutrophil/lymphocyte ratio (NLR), preoperative and postoperative prognostic nutrition index (PNI) levels were significant different between the POPF group and non-POPF group (P<0.05). Multivariate analysis results showed that: preoperative plasma albumin>35 g/L [OR=0.115, 95%CI was (0.038, 0.348)], postoperative plasma albumin>35 g/L [OR=0.126, 95%CI was (0.031, 0.516)], and postoperative NLR value≤6.65 [OR=0.149, 95%CI was (0.048, 0.461)] were the influencing factors of POPF after DP. The area under curve of postoperative NLR was 0.731 [95%CI was (0.639, 0.824)]. ConclusionPreoperative and postoperative plasma albumin>35 g/L, as well as postoperative NLR ≤6.65 are protective factors for POPF after DP, and postoperative NLR can be used as a predictor of POPF.
ObjectiveTo investigate the clinical effect of “Double R” pancreatojejunostomy in laparoscopic pancreaticoduodenectomy (LPD).MethodsThe clinical data of 20 patients underwent “Double R” pancreaticojejunostomy in the LPD from November 2018 to December 2019 in this hospital were collected retrospectively. The duration of pancreaticojejunostomy, incidence of postoperative pancreatic fistula, incidence of other complications, mortality, length of stay, and other clinical outcomes were analyzed.ResultsThere were 5 males and 6 females. The age was (56±10) years old. The body mass index was (22.6±4.4) kg/m2. The LPDs were successfully performed in all 20 patients, no patient transferred to the laparotomy, and no patient died within 30 d. There were 6 patients with papillary adenocarcinoma of the duodenum, 5 patients with adenocarcinoma of the lower part of the common bile duct, 2 patients with adenocarcinoma of the pancreatic duct, 3 patients with serous cystadenoma of the pancreatic head, 2 patients with intraductal papillary myxoma of the main pancreatic duct of the pancreatic head, 1 patient with duodenal adenoma with high grade intraepithelial neoplasia, 1 patient with metastatic renal clear cell carcinoma of the pancreatic head, 5 patients with soft pancreas, 12 patients with medium texture, 3 patients with hard texture. The diameter of distal pancreatic duct was (2.1±1.7) mm. The operative time was (380±69) min, the duration of pancreaticojejunostomy was (29±15) min, the intraoperative blood loss was (180±150) mL, the postoperative time of anal exhaust (2.2±0.8) d, postoperative time of fluid intake (3.5±1.1) d, postoperative time of half fluid intake (5.5±0.7) d, postoperative time of hospitalization (14±10) d. There were 3 complications in 2 patients, one of which suffered the pulmonary infection, the other suffered the delayed gastric emptying and gastrointestinal anastomosis bleeding, no bile leakage and abdominal hemorrhage happened. There were 2 cases of pancreatic fistula after the operation, all of them were biochemical pancreatic fistula.Conclusions“Double R” pancreaticojejunostomy method has some advantages of convenient operation, short operation time, and low incidence of pancreatic fistula. However, due to the limited sample size, its safety and feasibility still need to be verified by larger samples and more institutions.
ObjectiveTo investigate the role of local pancreatectomy for benign and low-grade malignant pancreatic tumors.MethodThe clinical data of 45 patients with benign and low-grade malignant pancreatic tumors who underwent local pancreatectomy from January 2014 to June 2019 in Union Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology were analyzed.ResultsForty-five patients underwent the local enucleation or resection with negative margin. The pathological results showed that there were 17 cases of solid pseudopapilloma, 5 cases of mucinous cystadenoma, 4 cases of serous cystadenoma, 10 cases of islet cell tumor, 5 cases of nonfunctional neuroendocrine tumor, 4 cases of congenital cyst. There were 6 cases of head of pancreas, 26 cases of body of pancreas, 8 cases of tail of pancreas, 5 cases of uncinate process. The tumor was 1.2 to 9.0 cm in diameter with an average of 3.2 cm. Among them, the diameter was more than 5.0 cm in 9 cases. The incidence of pancreatic fistula after operation was 57.8%, 65.4% was grade A fistula, 34.6% was grade B fistula, and no grade C fistula occurred. The incidence of abdominal infection was 13.3%, incidence of abdominal hemorrhage was 6.7%. There was no secondary diabetes mellitus and pancreatic endo- and exocrine dysfunction, and no death case.ConclusionsPancreatic enucleation for benign and low-grade malignant pancreatic tumors after strict preoperative evaluation can effectively preserve the pancreatic endocrine function of patients. Although the incidence of pancreatic fistula is high, it is mostly biochemical fistula, and the incidence of serious complications is low.
Objective To compare anastomotic fistula of modified triple-layer duct-to-mucosa pancreaticojejunostomy and end-to-end invagination pancreaticojejunostomy following pancreaticoduodenectomy. Methods The clinical data of 147 patients underwent pancreaticoduodenectomy from January 2015 to June 2017 in the West China Hospital of Sichuan University were retrospectively analyzed. The modified triple-layer duct-to-mucosa pancreaticojejunostomy were used in 101 cases (MTL group) and end-to-end invagination pancreaticojejunostomy were used in 46 cases (IPJ group). The differences of intraoperative and postoperative statuses were compared between the two groups. Results The baseline data of these two groups had no significant differences (P>0.05). Except for the average time of the pancreaticoenterostomy of the MTL group was significantly longer than that of the IPJ group (P<0.05), the intraoperative blood loss, the first postoperative exhaust time, postoperative hospitalization time, reoperation rate, death rate, and rates of complications such as the pancreatic fistula, biliary fistula, anastomotic bleeding, gastric emptying disorder, and intraperitoneal infection had no significant differences between these two groups (P>0.05). Conclusions Both modified triple-layer duct-to-mucosa pancreaticojejunostomy and end-to-end invagination pancreaticojejunostomy following pancreaticoduodenectomy are safe and effective. An individualized selection should be adopted according to specific situation of patient.
ObjectiveTo investigate value of drainage fluid amylase content and other risk factors in predicting clinically relevant postoperative pancreatic fistula (CR-POPF) after laparoscopic pancreaticoduodenectomy (LPD).MethodsThe clinical data of 166 patients who underwent LPD in this hospital from January 2017 to December 2019 were retrospectively analyzed. The independent risk factors of CR-POPF after LPD were analyzed. And the sensitivity and specificity of drainage fluid amylase content obtained on postoperative day 1 and 3 (Abbreviated as DFA1 and DFA3, respectively) in predicting CR-POPF by receiver operating characteristic (ROC) curve.ResultsA total of 166 patients underwent LPD were collected in this study. The CR-POPF occurred in 16 (9.6%) patients and all of them were grade B. The DFA1 (P=0.037), DFA3 (P<0.001), and positive bacterial culture of drainage fluid after operation (P=0.020) were the independent risk factors of CR-POPF after LPD (P<0.05) by the logistic regression multivariate analysis. The area under the ROC curve of the DFA1 and DFA3 in predicting CR-POPF was 0.880 [95%CI (0.812, 0.949)] and 0.912 [95%CI (0.853, 0.971)] respectively, and the corresponding best critical value was 3 925 and 939 U/L, and the sensitivity was 100% and 100%, specificity was 64.0% and 70.7%, respectively.ConclusionFor patients with DFA1>3 925 U/L, DFA3>939 U/L, and positive bacterial culture of drainage fluid after operation, preventive measures should be made to avoid CR-POPF.
Objective To summarize risk factors of pancreatic fistula after pancreaticoduodenectomy and to investigate clinical application of pancreatic fistula risk prediction system. Method The literatures of the risk factors and risk prediction of pancreatic fistula after the pancreaticoduodenectomy were collected to make a review. Results There were many risk factors for pancreatic fistula after pancreatoduodenectomy, including the patient’s own factors (gender, age, underlying diseases, etc.), disease related factors (pancreatic texture, diameter of pancreatic duct, pathological type, etc.), and surgical related factors (operation time, intraoperative blood loss, anastomosis, pancreatic duct drainage, etc.). The fistula risk prediction system after the pancreatoduodenectomy had a better forecast accuracy. Conclusions Occurrence of pancreatic fistula after pancreaticoduodenectomy is related to softness of pancreas and small diameter of pancreatic duct. Pancreatic fistula risk prediction system is helpful for prevention of pancreatic fistula after pancreaticoduodenectomy.
Objective To investigate the effect of sarcopenia on postoperative complications in patients undergoing pancreaticoduodenectomy（PD）. Methods The data of 225 patients who underwent pancreaticoduodenectomy in the Nanjing Hospital Affiliated to Nanjing Medical University (Nanjing First Hospital) from March 2012 to February 2020 were retrospectively analyzed. The total area of the skeletal muscle was measured by CT images at the level of the third lumbar vertebra for the diagnosis of sarcopenia. The patients were divided into sarcopenia group and non-sarcopenia group. The clinical data and surgical complications were compared between the two groups to explore the relationship between sarcopenia and postoperative complications. Results Compared with the non-sarcopenia group, the patients in the sarcopenia group were older and had lower hemoglobin concentration, lower serum albumin concentration, and higher total bilirubin levels (P<0.05). The incidences of clinically relevant pancreatic fistula (grade B and C fistula), pulmonary infection, atelectasis and hypoxemia in the sarcopenia group were significantly higher than those in the non-sarcopenia group (P<0.05). The length of ICU stay and perioperative mortality in the sarcopenia group were significantly higher than those in the non-sarcopenia group (P<0.05). Multivariate analysis showed that sarcopenia, preoperative total bilirubin level, pancreatic duct diameter and pancreatic texture were independent risk factors for clinically relevant pancreatic fistula (P<0.05). Sarcopenia, intraoperative blood loss and postoperative abdominal infection were independent risk factors for pulmonary complications after PD (P<0.05). Conclusions Sarcopenia is an independent risk factor for increased incidence of clinically relevant pancreatic fistula and pulmonary complications after PD. Strengthening perioperative nutritional therapy and rehabilitation exercise in patients with sarcopenia is of great significance to reduce postoperative complications of PD.
ObjectiveTo evaluate the effects of duct-to-mucosa pancreaticojejunostomy (dmPJ) and invagination pancreaticojejunostomy (iPJ) during pancreaticoduodenectomy (PD) on postoperative outcomes. MethodsPubmed, The Cochrane Library, Embase, Wanfang and CNKI database were searched to identify randomized controlled trials (RCTs) evaluating different type of pancreaticojejunostomy during PD. The literatures were screened according to inclusion and exclusion criteria. Quality assessment was conducted according to Jadad scoring system. ResultsNine RCTs were included, 1 032 patients were recruited, including 510 patients in dmPJ group and 522 patients in iPJ group. Meta-analysis indicated that there were no significant differences between two groups in terms of the incidence of pancreatic fistula in total (OR=0.95, P=0.78), clinical relevant pancreatic fistula (OR=0.78, P=0.71), overall morbidity (OR=0.93, P=0.60), perioperative mortality (OR=0.86, P=0.71), reoperation rate (OR=1.18, P=0.59), and length of hospital stay (WMD=-1.11, P=0.19). ConclusionDmPJ and iPJ are comparable in terms of pancreatic fistula and other complications.
