Project description:BackgroundPancreatic fistula remains a morbid complication after pancreatectomy. Since the proposed mechanism of pancreatic fistula is different between pancreaticoduodenectomy and distal pancreatectomy, we hypothesized that pancreatic gland texture and duct size are not associated with pancreatic fistula after distal pancreatectomy.MethodsAll patients ≥18 years in the 2014-15 American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) targeted pancreatectomy dataset were linked with the ACS NSQIP Public Use File (PUF). Pancreatic duct size (<3 mm, 3-6 mm, >6 mm) and pancreatic gland texture (hard, intermediate, soft) were categorized. Separate multivariable analyses were performed to evaluate associations between pancreatic duct size and gland texture after pancreaticoduodenectomy and distal pancreatectomy.ResultsA total of 9366 patients underwent pancreaticoduodenectomy or distal pancreatectomy during the study period. Proportion of pancreatic fistula was similar after distal pancreatectomy (606 of 3132, 19.4%) and pancreaticoduodenectomy (1163 of 6335, 18.4%, p = 0.245). Both pancreatic gland texture and duct size were significantly associated with pancreatic fistula after pancreaticoduodenectomy (p<0.001). However, there was no association between pancreatic fistula and gland texture or duct size (all p≥0.169) after distal pancreatectomy. Operative approach (minimally invasive versus open) was not associated with pancreatic fistula after distal pancreatectomy (p = 0.626). Patients with pancreatic fistula after distal pancreatectomy had increased rate of postoperative complications including longer length of stay, higher rates of readmission and reoperation compared to patients who did not have a pancreatic fistula (all p<0.001).ConclusionsUnlike among patients who had pancreaticoduodenectomy, pancreatic gland texture and duct size are not associated with development of pancreatic fistula following distal pancreatectomy. Other clinical factors should be considered in this patient population.

Project description:Postoperative pancreatic fistula is a critical complication after distal pancreatectomy. The aim of this systematic review is to assess new reports on the main pancreatic stump closure techniques (stapler and hand-sewn suture) in distal pancreatectomy, to define their influence on postoperative pancreatic fistula rates. A literature review was performed following PRISMA guidelines (PROSPERO: CRD42023408181). The survey was conducted in Medline (via PubMed) and EMBASE. Clinical trials and cohorts were included if they assessed pancreatic fistula rates after distal pancreatectomy, and excluded if they used a fistula rating system other than the ISGPF one. The risk of bias was assessed using the Study Quality Assessment Tools | NHLBI, NIH. A meta-analysis was presented as forest-plots. Eleven articles were included, representing 1498 patients. No significant difference was found between Suture and Bare stapler (95% CI 0.91-1.68) or Bare stapler and Reinforced stapler for A-graded fistula rates (95% CI 0.78-1.28) and B-graded fistula rates (I-squared = 0.0%, p = 0.784). Most articles showed unclear risk of detection bias. This meta-analysis found no difference in fistula rates between stump closure techniques. This choice should be made by surgeons' and hospital administration's preferences.

Project description:BackgroundTo evaluate the efficacy and safety of a modified pancreatic remnant-gastric coverage technique in laparoscopic distal pancreatectomy (LDP).MethodsThis retrospective study analyzed clinical data from 63 patients who underwent LDP between March 2017 and April 2024 at the Hepatobiliary and Pancreatic Surgery Department, The Affiliated LiHuiLi Hospital of Ningbo University. Patients were divided into two groups based on the pancreatic remnant management method: the experimental group (n = 28) underwent pancreatic remnant-gastric coverage, while the control group (n = 35) had the pancreatic remnant closed using a stapler followed by hand-sewn reinforcement. The parameters observed included general patient characteristics, intraoperative data, and postoperative data. We compared and analyzed all the above data between the two groups of patients both before and after propensity score matching (PSM).ResultsAll 63 patients were successfully operated. Before PSM, the incidence of POPF (Grade B/C) in the experimental group was significantly lower than in the control group (14.3% vs 34.3%, P < 0.05). And the incidence of POPF (BL) in the experimental group was lower than in the control group (39.3% vs 51.4%). After PSM, the difference in the incidence of POPF (Grade B/C) between the two groups remained statistically significant (16.0% vs 32.0%, P < 0.05). The incidence of POPF (BL) in the experimental group was also lower than in the control group (36.0% vs 56.0%). There were no statistically significant differences between the two groups in terms of operation time, pancreatic texture, thickness of pancreatic stump, intraoperative bleeding, intraoperative transfusion, post-pancreatectomy hemorrhage, abdominal infection, encapsulated effusion, or delayed gastric emptying both before and after PSM (P > 0.05).ConclusionThe use of the modified pancreatic remnant-gastric coverage in LDP effectively reduces the incidence of POPF and is both safe and feasible, making it a technique worth promoting.

Project description:BackgroundHighly utilized risk scores for clinically relevant postoperative pancreatic fistula (CR-POPF) have guided clinical decision-making in pancreatoduodenectomy. However, none has been successfully developed for distal pancreatectomy. This study aimed to develop and validate a new fistula risk score for distal pancreatectomy.MethodsPatients undergoing distal pancreatectomy at Helsinki University Hospital, Finland from 2013 to 2021, and at Karolinska University Hospital, Sweden, from 2010 to 2020, were included retrospectively. The outcome was CR-POPF, according to the 2016 International Study Group of Pancreatic Surgery definition. Preoperative clinical demographics and radiological parameters such as pancreatic thickness and duct diameter were measured. A logistic regression model was developed, internally validated with bootstrapping, and the performance assessed in an external validation cohort.ResultsOf 668 patients from Helsinki (266) and Stockholm (402), 173 (25.9 per cent) developed CR-POPF. The final model consisted of three variables assessed before surgery: transection site (neck versus body/tail), pancreatic thickness at transection site, and diabetes. The model had an area under the receiver operating characteristic curve (AUROC) of 0.904 (95 per cent c.i. 0.855 to 0.949) after internal validation, and 0.798 (0.748 to 0.848) after external validation. The calibration slope and intercept on external validation were 0.719 and 0.192 respectively. Four risk groups were defined in the validation cohort for clinical applicability: low (below 5 per cent), moderate (at least 5 but below 30 per cent), high (at least 30 but below 75 per cent), and extreme (75 per cent or more). The incidences in these groups were 8.7 per cent (11 of 126), 22.0 per cent (36 of 164), 63 per cent (57 of 91), and 81 per cent (17 of 21) respectively.ConclusionThe DISPAIR score after distal pancreatectomy may guide decision-making and allow a risk-adjusted outcome comparison for CR-POPF.

Project description:Postoperative pancreatic fistula (POPF) is a common complication following distal pancreatectomy (DP). However, the risk factors of this complication in patients after DP still remain controversial. The aim of our study is to estimate the association between potential risk factors and POPF. Relevant articles published up to June 21, 2016 were identified via PubMed, EMBASE, Web of Science, and The Cochrane Library. Studies that examined the risk factors of POPF following DP were enrolled. 20 articles (2070 patients) were finally included in this study. The pooled data suggested that patients with soft pancreas, higher Body Mass Index (BMI), blood transfusion, elevated intraoperative blood loss, and longer operative time had a decreased risk for POPF. However, age, gender, malignant pathology, types of stump closure, octreotide therapy, history of diabetes and chronic pancreatitis, splenectomy, multiorgan resection, main duct ligation, preoperative serum albumin levels, PGA felt wrapping, and extended lymphadenectomy could not be regarded as risk factors for POPF. Our analytic data demonstrated that pancreas texture, BMI, blood transfusion, intraoperative blood loss, and operative time were clinical predictor for POPF. This study may assist surgeons to screen patients with high risk of POPF and select appropriate treatment measures.

Project description:AimThe aim of this study was to evaluate the intra-abdominal status related to postoperative pancreatic fistula by combining postoperative fluid collection and drain amylase levels.MethodsWe retrospectively reviewed the data of 203 patients who underwent distal pancreatectomy and classified their postoperative abdominal status into four groups based on postoperative fluid collection size and drain amylase levels. We also evaluated the incidence of clinically relevant postoperative pancreatic fistula in each group according to C-reactive protein values.ResultsThe incidence of clinically relevant postoperative pancreatic fistula in the entire cohort (n = 203) was 28.1%. Multivariate analysis revealed that postoperative fluid collection, drain amylase levels, and C-reactive protein levels are considerable risk factors for clinically relevant postoperative pancreatic fistula. In the subgroup with large postoperative fluid collection and high drain amylase levels, 65.9% of patients developed clinically relevant postoperative pancreatic fistula. However, no significant difference was observed in C-reactive protein levels between patients with clinically relevant postoperative pancreatic fistula and those without it. In contrast, in the subgroup with a large postoperative fluid collection size or a high amylase level alone, a significant difference was observed in C-reactive protein values between the patients with clinically relevant postoperative pancreatic fistula and those without it.ConclusionPostoperative fluid collection status and the C-reactive protein value provide a more precise assessment of intra=abdominal status related to postoperative pancreatic fistula after distal pancreatectomy. This detailed analysis may be a clinically reasonable approach to individual drain management.

Project description:ObjectiveTo compare the intraoperative and postoperative outcomes of central pancreatectomy (CP) with distal pancreatectomy (DP).MethodsA systematic literature search was performed on electronic databases from MEDLINE, Embase, and PubMed from 1998 to 2018. Statistical analysis and meta-analysis were performed using statistics/data analysis (Stata®) software, version 12.0 (StataCorp LP, College Station, Texas 77845, USA). Dichotomous variables were analyzed by estimation of relative risk (RR) with a 95 percent (%) confidence interval (CI) and continuous variables were analyzed by standardized mean differences (SMD) with 95% CI.ResultsTwenty-four studies with 593 CP and 1226 DP were included in the meta-analysis. CP had significantly longer operation time (SMD: 1.03; 95% CI 0.62 to 1.44; P < 0.001) and lengthier postoperative hospital stay (SMD: 0.63; 95% CI 0.20 to 1.05; P < 0.001) and lengthier postoperative hospital stay (SMD: 0.63; 95% CI 0.20 to 1.05; P < 0.001) and lengthier postoperative hospital stay (SMD: 0.63; 95% CI 0.20 to 1.05; P < 0.001) and lengthier postoperative hospital stay (SMD: 0.63; 95% CI 0.20 to 1.05; P < 0.001) and lengthier postoperative hospital stay (SMD: 0.63; 95% CI 0.20 to 1.05; P < 0.001) and lengthier postoperative hospital stay (SMD: 0.63; 95% CI 0.20 to 1.05; P < 0.001) and lengthier postoperative hospital stay (SMD: 0.63; 95% CI 0.20 to 1.05; P < 0.001) and lengthier postoperative hospital stay (SMD: 0.63; 95% CI 0.20 to 1.05; P < 0.001) and lengthier postoperative hospital stay (SMD: 0.63; 95% CI 0.20 to 1.05; P < 0.01). Estimated blood loss was significantly lower in CP (SMD: -0.34; 95% CI -0.58 to -0.09; P = 0.007). Overall postoperative morbidity (RR: 1.30; 95% CI: 1.13 to 1.50; P < 0.001), overall pancreatic fistula (RR: 1.41; 95% CI: 1.20 to 1.66; P < 0.001), clinically relevant fistula (RR: 1.64; 95% CI: 1.25 to 2.16; P < 0.001), and postoperative hemorrhage (RR: 1.90; 95% CI: 1.18 to 3.06; P < 0.05) were all significantly higher after CP. On long-term follow-up, DP patients were more likely to have postoperative exocrine (RR: 0.56; 95% CI: 0.37 to 0.84; P < 0.05) and endocrine (RR: 0.27; 95% CI: 0.18 to 0.40; P < 0.001) insufficiency. There was no statistically significant difference in transfusion requirement, postoperative mortality, reoperation, and tumor recurrence.ConclusionCP is associated with significantly higher morbidity and clinically relevant pancreatic fistula. CP should only be reserved for selected patients who require postoperative pancreatic function preservation.

Project description:BackgroundIn pancreaticoduodenectomy, the pancreas-visceral fat CT value ratio and serrated pancreatic contour on preoperative CT have been revealed as risk factors for postoperative pancreatic fistulas. We aimed to evaluate whether they could also serve as risk factors for postoperative pancreatic fistulas after distal pancreatectomy.MethodsA total of 251 patients that underwent distal pancreatectomy at our department from 2006 to 2020 were enrolled for the study. We retrospectively analyzed risk factors for postoperative pancreatic fistulas after distal pancreatectomy using various pre and intraoperative factors, including preoperative CT findings, such as pancreas-visceral fat CT value ratio and serrated pancreatic contour.ResultsThe study population included 147 male and 104 female participants (median age, 68 years; median body mass index, 21.4 kg/m2), including 64 patients with diabetes mellitus (25.5%). Preoperative CT evaluation showed a serrated pancreatic contour in 80 patients (31.9%), a pancreatic thickness of 9.3 mm (4.0-22.0 mm), pancreatic parenchymal CT value of 41.8 HU (4.3-22.0 HU), and pancreas-visceral fat CT value ratio of - 0.41 (- 4.88 to - 0.04). Postoperative pancreatic fistulas were developed in 34.2% of the patients. Univariate analysis of risk factors for postoperative pancreatic fistulas showed that younger age (P = 0.005), high body mass index (P = 0.001), absence of diabetes mellitus (P = 0.002), high preoperative C-reactive protein level (P = 0.024), pancreatic thickness (P < 0.001), and high pancreatic parenchymal CT value (P = 0.018) were significant risk factors; however, pancreas-visceral fat CT value ratio (P = 0.337) and a serrated pancreatic contour (P = 0.122) did not serve as risk factors. Multivariate analysis showed that high body mass index (P = 0.032), absence of diabetes mellitus (P = 0.001), and pancreatic thickness (P < 0.001) were independent risk factors.ConclusionThe pancreas-visceral fat CT value ratio and serrated pancreatic contour evaluated using preoperative CT were not risk factors for postoperative pancreatic fistulas after distal pancreatectomy. High body mass index, absence of diabetes mellitus, and pancreatic thickness were independent risk factors, and a close-to-normal pancreas with minimal fat deposition or atrophy is thought to indicate a higher risk of postoperative pancreatic fistulas after distal pancreatectomy.

Project description:Peripancreatic fluid collections have been observed in most patients with postoperative pancreatic fistula after distal pancreatectomy; however, optimal management remains unclear. This study aimed to evaluate the management and outcomes of patients with postoperative pancreatic fistula and verify the significance of computed tomography values for predicting peripancreatic fluid infections after distal pancreatectomy. We retrospectively investigated 259 consecutive patients who underwent distal pancreatectomy. Grade B postoperative pancreatic fistula patients were divided into two subgroups (B-antibiotics group and B-intervention group) and outcomes were compared. Predictive factor analysis of peripancreatic fluid infection was performed. Clinically relevant postoperative pancreatic fistulas developed in 88 (34.0%) patients. The duration of hospitalization was significantly longer in the B-intervention (n = 54) group than in the B-antibiotics group (n = 31; 41 vs. 17 days, p < 0.001). Computed tomography values of the infected peripancreatic fluid collections were significantly higher than those of the non-infected peripancreatic fluid collections (26.3 vs. 16.1 Hounsfield units, respectively; p < 0.001). The outcomes of the patients with grade B postoperative pancreatic fistulas who received therapeutic antibiotics only were considerably better than those who underwent interventions. Computed tomography values may be useful in predicting peripancreatic fluid collection infection after distal pancreatectomy.
