Association of preoperative CT-scan features and clinically relevant postoperative pancreatic fistula after pancreaticoduodenectomy: a meta-analysis. ANZ J Surg 2024; 94:1030-1038. [PMID: 38837835 DOI: 10.1111/ans.19033] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2024] [Revised: 04/23/2024] [Accepted: 05/05/2024] [Indexed: 06/07/2024]
Abstract
BACKGROUND Clinically relevant postoperative pancreatic fistula (CR-POPF) is a significant complication after pancreaticoduodenectomy. CR-POPF is associated with various adverse outcomes, including high mortality rates. Identifying complication predictors for CR-POPF, such as preoperative CT scan features, including pancreatic attenuation index (PAI) and pancreatic duct diameter (PDD), is critical. This systematic review and meta-analysis consolidate existing literature to assess the impact of these variables on CR-POPF risk. METHODS Our comprehensive search, conducted in May 2023, covered PubMed, Scopus, Embase, and Web of Science databases. Inclusion criteria encompassed peer-reviewed cohort studies on pancreaticoduodenectomy, focusing on preoperative CT scan data. Case reports, case series, and studies reporting distal pancreatectomy were excluded. The quality assessment of included articles was done using New-Castle Ottawa Scale for cohort studies. Statistical analysis was carried out using Review Manager 5. This study was registered at the International Prospective Register of Systematic Reviews database (PROSPERO) on 12 May 2023 (registration number: CRD42023414139). RESULTS We conducted a detailed analysis of 38 studies with 7393 participants. The overall incidence of CR-POPF was 24%. Multiple linear regression analyses revealed that PDD and pancreatic parenchymal thickness were significantly associated with CR-POPF. CONCLUSION Our systematic review and meta-analysis shed light on CT scan findings for predicting CR-POPF after Whipple surgery. Age, PDD, and pancreatic parenchymal thickness significantly correlate with CR-POPF.

Simple Preoperative Imaging Measurements Predict Postoperative Pancreatic Fistula After Pancreatoduodenectomy. Ann Surg Oncol 2024; 31:1898-1905. [PMID: 37968411 PMCID: PMC10922305 DOI: 10.1245/s10434-023-14564-3] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2023] [Accepted: 10/22/2023] [Indexed: 11/17/2023]
Abstract
OBJECTIVE Postoperative pancreatic fistula is a potentially devastating complication after pancreatoduodenectomy (PD). The purpose of this study was to identify features on preoperative computed tomography (CT) imaging that correlate with an increased risk of postoperative pancreatic fistula (POPF). METHODS Patients who underwent PD at our high-volume pancreatic surgery center from 2019 to 2021 were included if CT imaging was available within 8 weeks of surgical intervention. Pancreatic neck thickness (PNT), abdominal wall thickness (AWT), and intra-abdominal distance from pancreas to peritoneum (PTP) were measured by two board-certified radiologists who were blinded to the clinical outcomes. Radiographic measurements, as well as preoperative patient characteristics and intraoperative data, were assessed with univariate and multivariable analysis (MVA) to determine risk for clinically relevant POPF (CR-POPF, grades B and C). RESULTS A total of 204 patients met inclusion criteria. Median PTP was 5.8 cm, AWT 1.9 cm, and PNT 1.3 cm. CR-POPF occurred in 33 of 204 (16.2%) patients. MVA revealed PTP > 5.8 cm (odds ratio [OR] 2.86, p = 0.023), PNT > 1.3 cm (OR 2.43, p = 0.047), soft pancreas consistency (OR 3.47, p = 0.012), and pancreatic duct size ≤ 3.0 mm (OR 4.55, p = 0.01) as independent risk factors for CR-POPF after PD. AWT and obesity were not associated with increased risk of CR-POPF. Patients with PTP > 5.8 cm or PNT > 1.3 cm were significantly more likely to suffer a major complication after PD (39.6% vs. 22.3% and 40% vs. 22.1%, p < 0.008). CONCLUSIONS Patients with a thick pancreatic neck and increased intra-abdominal girth have a heightened risk of CR-POPF after pancreatoduodenectomy, and they experience more serious postoperative complications. We defined a simple CT scan-based measurement tool to identify patients at increased risk of CR-POPF.

Abstract
INTRODUCTION Obesity is associated with increased morbidity and mortality post surgery. The measurement of visceral obesity can predict postoperative outcomes after pancreaticoduodenectomy. METHODS This is a prospective observational study. Visceral obesity was calculated by measuring the fat thickness in the retro-renal area by using a computed tomography scan. Visceral obesity was defined as retro-renal fat thickness (RRFT) of ≥ 2 cm. Patients were divided into two groups: Group-A (RRFT < 2 cm, non-obese) and Group-B (RRFT > 2 cm, obese). Demographic, clinical, and intraoperative variables were correlated with postoperative outcomes. RESULTS Fifty-six patients were included in the study. Thirty-two patients were included in Group-A, and 24 patients were included in Group-B. The two groups had comparable outcomes. A total of 21 patients in Group-A (65.62%) and 17 patients in Group-B (70.83%) had comorbidities, including diabetes mellitus, hypertension, and coronary disease (p=0.680). American Society of Anesthesiologists (ASA) grading was comparable (p=0.927). BMI was also comparable (p=0.354). Type of pancreaticoduodenectomy, pancreatic texture, pancreatic duct diameter, and technique of pancreaticojejunostomy anastomosis were comparable. The mean operative time was longer in Group-B (362 ± 36.2 min vs. 298 ± 45.2 min) (p=0.001). Intraoperative blood loss was more in Group-B (312 ± 36.8 ml vs. 267 ± 23.7 ml) (p=0.001). The rates of postoperative pancreatic fistula and delayed gastric emptying were comparable (p=0.402 and p=0.134, respectively). The length of hospital stay was longer in patients in Group-B (p=0.004). There was one death in Group-B (obese group). CONCLUSION Visceral obesity is a risk factor for postoperative complications after a pancreaticoduodenectomy.

Abstract
BACKGROUND Bioelectric impedance vector analysis (BIVA) is a reliable tool to assess body composition. The aim was to study the association of BIVA-derived phase angle (PA) and standardized PA (SPA) values and the occurrence of surgery-related morbidity. METHODS Patients undergoing hepatectomy for cancer in two Italian centers were prospectively enrolled. BIVA was performed the morning of surgery. Patients were then stratified for the occurrence or not of postoperative morbidity. RESULTS Out of 190 enrolled patients, 76 (40%) experienced postoperative complications. Patients with morbidity had a significant lower PA, SPA, body cell mass, and skeletal muscle mass, and higher extracellular water and fat mass. At the multivariate analysis, presence of cirrhosis (OR 7.145, 95% CI:2.712-18.822, p < 0.001), the Charlson comorbidity index (OR 1.236, 95% CI: 1.009-1.515, p = 0.041), the duration of surgery (OR 1.004, 95% CI:1.001-1.008, p = 0.018), blood loss (OR 1.002. 95% CI: 1.001-1.004, p = 0.004), dehydration (OR 10.182, 95% CI: 1.244-83.314, p = 0.030) and SPA < -1.65 (OR 3.954, 95% CI: 1.699-9.202, p = 0.001) were significantly and independently associated with the risk of complications. CONCLUSION Introducing BIVA before hepatic resections may add valuable and independent information on the risk of morbidity.

Abstract
BACKGROUND Pancreatoduodenectomy (PD) is the only cure for periampullary and pancreatic cancer. It has morbidity rates of 40-60%, with severe complications in 30%. Prediction models to predict complications are crucial. A risk model for severe complications was developed by Schroder et al. based on BMI, ASA classification and Hounsfield Units of the pancreatic body on the preoperative CT scan. These variables were independent predictors for severe complications upon internal validation. Our aim was to externally validate this model using an independent cohort of patients. METHODS A retrospective analysis was performed on 318 patients who underwent PD at our institution from 2013 to 2021. The outcome of interest was severe complications Clavien-Dindo ≥ IIIa. Model calibration, discrimination and performance were assessed. RESULTS A total of 308 patients were included. Patients with incomplete data were excluded. A total of 89 (28.9%) patients had severe complications. The externally validated model achieved: C-index = 0.67 (95% CI: 0.60-0.73), regression coefficient = 0.37, intercept = 0.13, Brier score = 0.25. CONCLUSIONS The performance ability, discriminative power, and calibration of this model were acceptable. Our risk calculator can help surgeons identify high-risk patients for post-operative complications to improve shared decision-making and tailor perioperative management.

Abstract
BackgroundPostoperative pancreatic fistula (POPF) is the most critical complication after pancreatoduodenectomy (PD). Preoperative identification of high-risk patients and optimal pancreatic reconstruction technique can be a way to reduce postoperative complications.MethodsA series of 386 patients underwent PD over a 10-year period (2009–2019). On routinely performed preoperative computed tomography (CT) images, the ventro-dorsal diameters of duct (D) and parenchyma (P) were measured in the cutting plane at the superior mesenteric vein. Then, the ratio of both values was calculated (D/P ratio) Double-layer pancreatojejunostomy with alignment of duct and mucosa (ADAM) by two monofilament threads (MFT) was performed in 359 patients and pancreatogastrostomy (PG) in 27 patients. The incidence of POPF was diagnosed according to the International Study Group for Pancreatic Fistula criteria.ResultsThe overall rate of POPF was 21% (n = 80), and the rate of clinically relevant type B/C fistulas 6.5% (n = 25). A D/P ratio of <0.2 was significantly associated with type B/C fistula (11%, p < 0.01). In low-risk patients (D/P ratio >0.2), type B/C fistula occurred only in 2%, and in high-risk patients (D/P ratio <0.2) in 9%. ADAM anastomosis was performed safely by two different surgeons. A PG anastomosis had double-digit POPF rates in all groups.ConclusionPreoperative CT imaging with D/P measurement may predict the risk of POPF development. A cut off D/P ratio of <0.2 was significantly associated with clinical relevant POPF. ADAM anastomosis may be an option for pancreatojejunostomy. However, preoperative knowledge of the D/P ratio could guide decision-making for primary pancreatectomy when pancreatic reconstruction is critical.

Abstract
Body composition changes during neoadjuvant therapy and their clinical significance have not been clarified. The present study aimed to investigate body composition changes during neoadjuvant chemoradiation therapy (NACRT) in patients with distal bile duct cancer and the clinical impact on postoperative complications and the prognosis. A total of 16 patients with distal bile duct cancer who underwent curative resection after NACRT were retrospectively evaluated. The area of skeletal muscle, visceral fat and subcutaneous fat on computed tomography and immunological and nutritional indices were assessed before and after NACRT. All 16 patients completed NACRT followed by pancreaticoduodenectomy without mortality. There was no significant change in the skeletal muscle mass index (SMI) during NACRT. Of the 16 patients, nine (56%) were defined as sarcopenic before NACRT, and eight (50%) met the criteria for sarcopenic after NACRT. The SMI and total fat area were significantly associated with postoperative pancreatic fistula (POPF) (P=0.019 and P=0.007, respectively). The patients with sarcopenia had a shorter disease-free survival time and overall survival time in comparison to patients without sarcopenia (P=0.025 and P=0.115, respectively). In conclusion, NACRT for distal bile duct cancer did not significantly affect the body composition, or the immunological or nutritional indices. Sarcopenia after NACRT was significantly associated with early recurrence in patients with distal bile duct cancer who received NACRT.

Abstract
OBJECTIVE The aim of the study was to evaluate whether fatty pancreas could be estimated by fat mass measurement by preoperative bioelectric impedance analysis. Preoperative computed tomography scan and pathologic evaluation were used as validation methods. Moreover, the 3 methodologies were tested for their ability in predicting postoperative pancreatic fistula. METHODS Seventy-five patients who underwent pancreatic resection were analyzed. Preoperative computed tomography attenuation in Hounsfield unit (CT-HU) was used to assess fatty pancreas. Bioelectric impedance analysis was performed the day before surgery and fat mass index (FMI) was calculated. Pancreatic steatosis was assessed by pathologists at the line of surgical transection. The ability of the methods in predicting postoperative pancreatic fistula was evaluated by the area under the receiver operating characteristics curves. RESULTS There was a strong correlation between CT-HU values and grade of pancreatic steatosis evaluated at histology ( r = -0.852, P < 0.001) and a moderate correlation between FMI and histologic pancreatic steatosis ( r = 0.612, P < 0.001) and between CT-HU value and FMI ( r = -0.659, P < 0.001) values. The area under the curve (95% confidence interval) was 0.942 (0.879-1) for histology, 0.924 (0.844-1) for CT-HU, and 0.884 (0.778-0.990) for FMI. CONCLUSIONS Bioelectric impedance analysis represents a valid alternative to assess pancreatic steatosis.

Abstract
BACKGROUND Multiple risk scores claim to predict the probability of postoperative pancreatic fistula (POPF) after pancreatoduodenectomy. It is unclear which scores have undergone external validation and are the most accurate. The aim of this study was to identify risk scores for POPF, and assess the clinical validity of these scores. METHODS Areas under receiving operator characteristic curve (AUROCs) were extracted from studies that performed external validation of POPF risk scores. These were pooled for each risk score, using intercept-only random-effects meta-regression models. RESULTS Systematic review identified 34 risk scores, of which six had been subjected to external validation, and so included in the meta-analysis, (Tokyo (N=2 validation studies), Birmingham (N=5), FRS (N=19), a-FRS (N=12), m-FRS (N=3) and ua-FRS (N=3) scores). Overall predictive accuracies were similar for all six scores, with pooled AUROCs of 0.61, 0.70, 0.71, 0.70, 0.70 and 0.72, respectively. Considerably heterogeneity was observed, with I2 statistics ranging from 52.1-88.6%. CONCLUSION Most risk scores lack external validation; where this was performed, risk scores were found to have limited predictive accuracy. . Consensus is needed for which score to use in clinical practice. Due to the limited predictive accuracy, future studies to derive a more accurate risk score are warranted.

Abstract
BACKGROUND Postoperative Pancreatic Fistula (POPF) is a common and serious complication after Distal Pancreatectomy (DP). An effective and accepted score to predict the occurrence of Clinically Relevant (CR-) POPF does not exist. METHODS Data regarding 103 consecutive patients undergoing DP from 2015 to 2019 were collected. A multivariate logistic regression was performed, in order to build a simplified score. The accuracy in predicting a categorical outcome was evaluated using the Receiver Operating Characteristic (ROC) curves. Youden's J test was performed to evaluate the performance of a positive score on the POPF occurrence. RESULTS 33 patients developed a CR-POPF. Based on multivariate analysis results, a 4 points score was created by assigning 1 point if operation time was >4 hours, amylase levels on drains' fluid >500 UI on POD 3, pancreatic thickness >10mm and if the BMI was > 30. The discriminating ability was tested on the ROC curve, showing an area under the curve of 0.83 (CI 95%=0.75 - 0.92). The score threshold was determined at 2 points/4, the highest value according to the Youden index (0.53). The sensitivity is calculated at 82% (CI95% 69-95) and the specificity at 71 (CI95% 61 - 82). A threshold of 3 points/4 allows to reach a specificity of 99% (CI95% 99 - 100). CONCLUSIONS An easy to use post-operative score based on operation time, obesity, amylase level on drains on POD3 and pancreatic thickness on preoperative CT seems to predict the risk of developing CR-POPF.

Abstract
Clinically relevant postoperative pancreatic fistula (CR-POPF) is a life-threatening complication following pancreaticoduodenectomy (PD). Individualized preoperative risk assessment could improve clinical management and prevent or mitigate adverse outcomes. The aim of this study is to develop a machine learning risk model to predict occurrence of CR-POPF after PD from preoperative computed tomography (CT) scans. A total of 100 preoperative high-quality CT scans of consecutive patients who underwent pancreaticoduodenectomy in our institution between 2011 and 2019 were analyzed. Radiomic and morphological features extracted from CT scans related to pancreatic anatomy and patient characteristics were included as variables. These data were then assessed by a machine learning classifier to assess the risk of developing CR-POPF. Among the 100 patients evaluated, 20 had CR-POPF. The predictive model based on logistic regression demonstrated specificity of 0.824 (0.133) and sensitivity of 0.571 (0.337), with an AUC of 0.807 (0.155), PPV of 0.468 (0.310) and NPV of 0.890 (0.084). The performance of the model minimally decreased utilizing a random forest approach, with specificity of 0.914 (0.106), sensitivity of 0.424 (0.346), AUC of 0.749 (0.209), PPV of 0.502 (0.414) and NPV of 0.869 (0.076). Interestingly, using the same data, the model was also able to predict postoperative overall complications and a postoperative length of stay over the median with AUCs of 0.690 (0.209) and 0.709 (0.160), respectively. These findings suggest that preoperative CT scans evaluated by machine learning may provide a novel set of information to help clinicians choose a tailored therapeutic pathway in patients candidated to pancreatoduodenectomy.

A simple preoperative stratification tool predicting the risk of postoperative pancreatic fistula after pancreatoduodenectomy. Pancreatology 2021; 21:957-964. [PMID: 33775565 DOI: 10.1016/j.pan.2021.03.009] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/20/2020] [Revised: 01/28/2021] [Accepted: 03/14/2021] [Indexed: 12/11/2022]
Abstract
BACKGROUND Postoperative pancreatic fistula (POPF) after pancreatoduodenectomy (PD) can be associated with severe postoperative morbidity. This study aims to develop a preoperative POPF risk calculator that can be easily implemented in clinical routine. METHODS Patients undergoing PD were identified from a prospectively-maintained database. A total of 11 preoperative baseline and CT-based radiological parameters were used in a binominal logistic regression model. Parameters remaining predictive for grade B/C POPF were entered into the risk calculator and diagnostic accuracy measures and ROC curves were calculated for a training and a test patient cohort. The risk calculator was transformed into a simple nomogram. RESULTS A total of 242 patients undergoing PD in the period from 2012 to 2018 were included. CT-imaging-based maximum main pancreatic duct (MPD) diameter (p = 0.047), CT-imaging-based pancreatic gland diameter at the anticipated resection margin (p = 0.002) and gender (p = 0.058) were the parameters most predictive for grade B/C POPF. Based on these parameters, a risk calculator was developed to identify patients at high risk of developing grade B/C POPF. In a training cohort of PD patients this risk calculator was associated with an AUC of 0.808 (95%CI 0.726-0.874) and an AUC of 0.756 (95%CI 0.669-0-830) in the independent test cohort. A nomogram applicable as a visual risk scale for quick assessment of POPF grade B/C risk was developed. CONCLUSION The preoperative POPF risk calculator provides a simple tool to stratify patients planned for PD according to the risk of developing postoperative grade B/C POPF. The nomogram visual risk scale can be easily integrated into clinical routine and may be a valuable model to select patients for POPF-preventive therapy or as a stratification tool for clinical trials.

Surgeon vs Pathologist for Prediction of Pancreatic Fistula: Results from the Randomized Multicenter RECOPANC Study. J Am Coll Surg 2021; 232:935-945.e2. [PMID: 33887486 DOI: 10.1016/j.jamcollsurg.2021.03.024] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2021] [Revised: 03/07/2021] [Accepted: 03/10/2021] [Indexed: 12/20/2022]
Abstract
BACKGROUND Surgically assessed pancreatic texture has been identified as the strongest predictor of postoperative pancreatic fistula. However, texture is a subjective parameter with no proven reliability or validity. Therefore, a more objective parameter is needed. In this study, we evaluated the fibrosis level at the pancreatic neck resection margin and correlated fibrosis and all clinico-pathologic parameters collected over the course of the Pancreatogastrostomy vs Pancreatojejunostomy for RECOnstruction (RECOPANC) study. STUDY DESIGN The RECOPANC trial was a multicenter randomized prospective trial of patients undergoing pancreatoduodenectomy. There were 261 hematoxylin and eosin-stained slides allocated for histopathologic analyses. Pancreatic fibrosis was scored from 0 to III (no fibrosis up to severe fibrosis) by 2 blinded independent pathologists. All variables possibly associated with POPF were entered into a generalized linear model for multivariable analysis. RESULTS The fibrosis grade and pancreatic texture were scored in all 261 patients. In POPF B/C (postoperative pancreatic fistula grade B or C) patients, 71% had a soft pancreas, and fibrosis grades were distributed as follows: 48% with score 0, 28% with score I, 20% with score II, and 7% with score III, respectively. Fibrosis grading showed substantial inter-rater reliability (kappa = 0.74) and correlated positively with hard pancreatic texture (p < 0.05). In univariable analysis, area under the curve (AUC) for POPF B/C prediction was higher for fibrosis grade than for pancreatic texture (0.71 vs 0.59). In multivariate analysis, the following predictors were selected: sex, surgeon volume, pancreatic texture, and fibrosis grade. However, the addition of pancreatic texture only led to an incremental improvement (AUC 0.794 vs 0.819). CONCLUSIONS Histologically evaluated pancreatic fibrosis is an easily applicable and highly reproducible POPF predictor and superior to surgically evaluated pancreatic texture. Future studies might use fibrosis grade for risk stratification in pancreatoduodenectomy.

Perioperative acinar cell count method works well in the prediction of postoperative pancreatic fistula and other postoperative complications after pancreaticoduodenectomy. Pancreatology 2021; 21:487-493. [PMID: 33531257 DOI: 10.1016/j.pan.2021.01.005] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/17/2020] [Revised: 11/30/2020] [Accepted: 01/10/2021] [Indexed: 12/11/2022]
Abstract
BACKGROUND Earlier we have shown that high frequency of acinar cells in the pancreatic transsection line predicts postoperative pancreatic fistula after pancreaticoduodenectomy (PD). Acinar cell count method (ACM) is fast to perform during operation. In this study our aim was to validate the accuracy of ACM to compare it with other published risk prediction methods. METHODS 87 patients who underwent PD without any trial including perioperative medications were collected from a single hospital. Data on demographics, surgical details, postoperative complications clinically relevant pancreatic fistulae (CR-POPF) and clinically relevant Clavien-Dindo complications (CR-CDC) were registered. Thirteen previously published risk prediction methods were included in the comparison, such as pancreatic duct diameter, palpable texture of pancreas, Braga score (BC), Fistula Risk Score, Modified Fistula Risk Score, Alternative Fistula Risk Score and multiple radiological parameters. ROC-curves were calculated to compare sensitivity and specificity for identifying high risk patients for CR-POPF and CR-CDC. RESULTS The three most accurate risk prediction methods for CR-POPF were ACM (sensitivity 88.9%, specificity 52.6%; p = 0.043), BC (87.5%, 56.6%; p = 0.039) and visceral fat area to subcutaneous fat area ratio (75.5%, 80.0%; p = 0.032). In predicting CR-CDC the three most accurate methods were ACM (73.9%, 56.2%; p = 0.033), BC (68.4%, 59.5%; p = 0.036) and TPAI (78.3%, 41.7%; p = 0.012). CONCLUSION ACM was shown to be as good as the more complicated risk scoring methods in the prediction of CR-POPF. It was good also in predicting all clinically relevant complications. ACM is easy to use during operation and can be recommended as a routine risk prediction method.

A deep pancreas is a novel predictor of pancreatic fistula after pancreaticoduodenectomy in patients with a nondilated main pancreatic duct. Surgery 2020; 169:1471-1479. [PMID: 33390302 DOI: 10.1016/j.surg.2020.11.033] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2020] [Revised: 11/20/2020] [Accepted: 11/20/2020] [Indexed: 12/21/2022]
Abstract
BACKGROUND We investigated the risk factors for clinically relevant postoperative pancreatic fistula after pancreaticoduodenectomy in patients with a nondilated main pancreatic duct. METHODS We investigated a total of 354 patients who underwent pancreaticoduodenectomy. The diameter of the main pancreatic duct, the shortest distance from the body surface to the pancreas (the pancreatic depth), and the computed tomography attenuation index (the difference between the pancreatic and splenic computed tomography attenuation) were measured in preoperative computed tomography. RESULTS One hundred eighty-one (51.1%) patients had a nondilated main pancreatic duct, and 50 (27.6%) of the 181 patients with a nondilated main pancreatic duct developed a clinically relevant postoperative pancreatic fistula. Univariate analyses revealed that the calculated body mass index (≥21.8 kg/m2) (P = .004), deep pancreas (pancreatic depth ≥51.2 mm) (P = .001), and low computed tomography attenuation index (≤-3.8 Hounsfield units) (P = .02) were significant risk factors for clinically relevant postoperative pancreatic fistula. The multivariate logistic regression analysis revealed that deep pancreas (odds ratio 2.370; 95% confidence interval 1.0019-5.590; P = .049) was an independent risk factor for clinically relevant postoperative pancreatic fistula. Among patients with a nondilated main pancreatic duct, deep pancreas (in comparison to patients without deep pancreas) was associated with male sex (72.7% vs 54.9%; P = .016), higher body mass index (22.5 kg/m2 vs 19.6 kg/m2; P < .001), a history of diabetes mellitus (24.5% vs 8.5%; P = .006), a lower computed tomography attenuation index (-9.6 Hounsfield units vs -4.6 Hounsfield units; P = .007), a longer operative time (454 minutes vs 420 minutes; P = .007), and a higher volume of intraoperative blood loss (723 mL vs 500 mL; P < .001), respectively. CONCLUSION Deep pancreas may be an important parameter associated with significant risk factors for clinically relevant postoperative pancreatic fistula after pancreaticoduodenectomy in patients with a nondilated main pancreatic duct.

Abstract
BACKGROUND Pancreatic fistula after pancreaticoduodenectomy is one of the most severe complications with mortality rates as high as 45%, and the prediction of most severe form of fistula (grade C) is crucial for successful management of patients who are to undergo cephalic pancreatoduodenectomy. It has been found that the amount of abdominal fat may predict grade C postoperative pancreatic fistula. In this study, we analysed the value of retrorenal fat thickness in the prediction of grade C pancreatic fistula. METHODS A total of 140 patients who underwent pancreaticoduodenectomy were retrospectively analysed. Retrorenal fat thickness and intra-abdominal fat, expressed as total fat area, visceral fat area and subcutaneous fat area, were determined from computed tomography slices using the known range of attenuation values (-190 to -30). Blood loss, operating time, pancreatic texture and main pancreatic duct diameter as well as body mass index were also analysed. RESULTS Retrorenal fat thickness (P = 0.0004), duct diameter (P = 0.0008), subcutaneous fat area (P = 0.023) and total fat area (P = 0.014) were found to be significant predictors of grade C pancreatic fistula. CONCLUSION Although retrorenal fat tissue thickness may seem robust, it is a simple measure that can be used to predict the most severe grade of pancreatic fistula after pancreaticoduodenectomy.

Abstract
BACKGROUND Distal pancreatectomy (DP) is the main surgical treatment of benign and malignant lesions located in pancreatic body and tail. Postoperative pancreatic fistula (POPF) following DP is still a considerable cause of morbidity. Identification of risk factors for POPF after DP might provide some preventive applications. We aimed to evaluate the factors affecting POPF after DP and to present a new and easy radiological predictive factor. MATERIALS AND METHODS Thirty-four patients underwent DP with stapler closure were included. Several risk factors for clinically relevant POPF (CR-POPF) were analyzed. Additionally, computed tomography findings of pancreatic thickness (PT), main pancreatic duct diameter (MPDD), and PT/MPDD ratio were evaluated for POPF. RESULTS CR-POPF was observed in 10 patients (29.4%). Univariate and multivariate analyses showed that previous abdominal surgery and PT/MPDD ratio were predictive factors for CR-POPF after DP (P = 0.040, P = 0.034, respectively). The cutoff value for the PT/MPDD ratio was 8. CONCLUSION A PT/MPDD ratio greater than 8 (a wide pancreas with a narrow duct) is a significant predictive factor for CR-POPF following DP.

Abstract
BACKGROUND Body composition analysis has emerged as a practical tool for predicting outcomes following pancreatic surgery. However, the impact of body composition disorders on clinically relevant postoperative pancreatic fistula (CR-POPF) remains inconclusive. The aim of this study was to review and analyse whether radiographically assessed body composition is predictive of CR-POPF. METHODS PubMed, MEDLINE, Web of Science, and the Cochrane Library databases were searched up to January 2020 to identify relevant studies. CR-POPF was defined according to the definition and grading system proposed by the International Study Group on Pancreatic Surgery (ISGPS). Pooled odds ratios (OR) for CR-POPF were calculated to evaluate the predictive values of radiographically assessed body composition. RESULTS Fifteen studies published between 2008 and 2019 with a total of 3136 patients were included. There was a significant increase in the incidence of CR-POPF in patients with visceral obesity (OR 2.97, 95% CI 2.05-4.29, P < 0.00001) and sarcopenic obesity (OR 2.88, 95% CI 1.31-6.34, P = 0.009). Conversely, the impact of sarcopenia (OR 0.91, 95% CI 0.65-1.28, P = 0.59) and low muscle attenuation (MA) on CR-POPF did not reach statistical significance. CONCLUSION Preoperative visceral obesity and sarcopenic obesity are more effective at predicting CR-POPF than decreased muscle quantity and quality. This finding may lead to appropriate management and early intervention of patients at risk of CR-POPF.

Abstract
Background Postoperative pancreatic fistula (POPF) is a life-threatening postoperative complication. The aim of this study was to evaluate the efficacy of the fistula risk score (FRS) and preoperative body composition factors for predicting the occurrence of clinically relevant POPF (CR-POPF) after pancreaticoduodenectomy (PD). Methods In this study, 136 consecutive patients who underwent PD between 2006 and 2018 were enrolled. The risk factors of CR-POPF (grades B and C) were analyzed. Preoperative visceral adipose tissue area (VATA), skeletal mass index (SMI), and subcutaneous adipose tissue area (SATA) were calculated from computed tomography data. Results The overall 30-day mortality and morbidity rates were 0.7 and 38%, respectively. The incidence rates of grade B and C CR-POPF were 27 and 4%, respectively. A univariate analysis revealed that male sex, habitual smoking, prognostic nutritional index (PNI) < 45, VATA ≥90, VATA/SATA ≥0.9, VATA/SMI ≥ 1.4, and FRS > 4 were significantly associated with the incidence of CR-POPF. A multivariate analysis revealed that PNI < 45, VATA/SMI ≥ 1.4 and FRS > 4 were the independent risk factors of CR-POPF. Conclusions Preoperative anthropomorphic imbalance, PNI, and FRS were independent risk factors for CR-POPF. Patients with high-risk factors should be closely monitored during the postoperative period.

Abstract
BACKGROUND Pancreatic fistula is a common complication after pancreaticoduodenectomy, which could be caused by: soft pancreatic tissue, pancreatic duct diameter < 3 mm and body mass index ≥25 kg/m2. Here we report a case of pancreatic fistula due to obstruction of the jejunal loop due to compression of the jejunal loop by the superior mesenteric vessels. CASE PRESENTATION A 68-year-old man was admitted to our ward due to intermittent epigastric distension and pain. After various examinations and treatments, he was diagnosed with middle bile duct cancer. Pancreaticoduodenectomy was performed, and pancreaticojejunostomy and hepaticojejunostomy were completed by lifting the jejunal loop from behind the superior mesenteric vessels to the upper region of the colon. On postoperative day 9, the patient developed acute diffuse peritonitis, and on postoperative day 10, the patient underwent a second exploratory laparotomy, during which it was confirmed that the pancreatic fistula was caused by obstruction of the jejunal loop due to compression of the jejunal loop by the superior mesenteric vessels, then the patient recovered and was discharged alive after retrograde drainage in the jejunum. CONCLUSIONS The superior mesenteric vessels after pancreaticoduodenal surgery can compress the jejunal loop and cause obstruction leading to serious complications, and it is recommended that general surgeons should avoid lifting the jejunal loop from the posterior aspect of the superior mesenteric vessels to complete the anastomosis.

Abstract
OBJECTIVES Postoperative pancreatic fistula (POPF) is the most threatening complication after pancreatectomy. This study aimed to directly assess pancreatic fatty infiltration with preoperative computed tomography (CT) imaging and to investigate whether a preoperative analysis of patient variables, including CT characteristics and clinical factors, can predict POPF. METHODS We enrolled 150 consecutive patients who underwent curative pancreatectomy. Radiographic factors, including pancreatic fat volume, were measured using preoperative CT imaging and the predictive factors were explored using univariate and multivariate analyses. RESULTS POPF developed in 30 patients (20.0%). The ratio of pancreatic fat (RPF) ≥ 4.83% was associated with a risk of POPF, high body mass index (BMI), and obese body habitus. Patients with POPF were significantly more likely to have high BMI (≥ 25 kg/m2), obese body habitus, and an RPF ≥ 4.83% than patients without POPF. In the multivariate analysis, visceral fat area/skeletal muscle index (VFA/SMI) ≥ 1.94 (odds ratio [OR] 4.28, 95% confidence interval [CI] 1.43-12.9, p = 0.0095) was the sole independent predictive factor for POPF. For patients with a soft pancreas, VFA/SMI ≥ 1.94 (OR 5.67, 95% CI 2.05-15.7, p = 0.0008) was again the sole independent predictive factor for POPF. CONCLUSION Preoperative CT images can examine pancreatic fatty infiltration, and patients who had POPF were significantly associated with a high RPF. Among several parameters, VFA/SMI was the only independent predictive factor for clinically relevant POPF. Preoperative evaluation of these body composition variables and the pancreatic configuration could be useful for predicting POPF.

Preoperative adiposity at bioimpedance vector analysis improves the ability of Fistula Risk Score (FRS) in predicting pancreatic fistula after pancreatoduodenectomy. Pancreatology 2020; 20:545-550. [PMID: 31980350 DOI: 10.1016/j.pan.2020.01.008] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2019] [Revised: 01/02/2020] [Accepted: 01/14/2020] [Indexed: 12/11/2022]
Abstract
BACKGROUND Anthropometric parameters have been associated with increased risk of clinically relevant postoperative pancreatic fistula (CR-POPF) after pancreaticoduodenectomy (PD). Nonetheless, conventional metrics to predict POPF do not include the assessment of body composition. We aimed to validate the most used Fistula Risk Score (FRS), and to assess whether the appraisal of adipose compartment at bioimpedance vector analysis (BIVA) improves the accuracy of FRS in CR-POPF prediction. METHOD PD patients from 3 Italian academic institutions were prospectively included over a 2-year period. Patients with ASA score ≥3, heart failure, chronic kidney disease, or compartmentalized fluid collections were excluded. BIVA was performed on the day prior to surgery. CR-POPF occurrence and severity were classified per the ISGPS classification. RESULTS Out of 148 PDs, 84 patients (56.8%) had pancreatic cancer, and 29 (19.6%) experienced CR-POPF. FRS elements, namely soft pancreatic texture (p = 0.009), small pancreatic duct diameter (p = 0.029), but not blood loss (p = 0.450), as well as high BMI (p = 0.004) were associated with CR-POPF. Also, the preoperative fat mass (FM) amount measured at BIVA was significantly higher in patients who developed CR-POPF, compared to those who did not (median FM = 19.4 kg/m2 vs. 14.4 kg/m2, respectively; p = 0.005). The predictive ability of a multivariate model adding FM to the FRS, assessed at the receiver operating characteristics curve showed a higher accuracy than the FRS alone (AUC = 0.774 and AUC = 0.738, respectively). CONCLUSIONS Assessment of preoperative FM at BIVA can improve the accuracy of FRS in predicting CR-POPF following pancreatoduodenectomy.

Abstract
BACKGROUND & AIM The perioperative severe changes in the nutritional and metabolic homeostasis are, by some means, proportional to the extent of tissue injury and magnitude of operative trauma. An adequate qualitative and quantitative replacement of nutritional substrates are of utmost importance to facilitate proper tissue healing and recovery and maintenance of organ function after surgery. METHODS The present manuscript has been planned to put the most recent research of the Milano-Bicocca University surgical working group in the context of a more personalized nutritional therapy and metabolic care for surgical patients. Particular prominence has been given to major pancreatic resections because these surgeries are among the most complex and challenging operations for the degree of parenchyma resection and tissue dissection, the consequent overall injury, and the fairly high rate of major complications resulting in a catabolic response. RESULTS Anthropometric parameters and particularly sarcopenia, visceral obesity - and their relative proportion -, are strongly associated with poor outcome after pancreatic surgery. Adequate perioperative nutritional therapy is of utmost importance in affecting morbidity. Long-term nutritional and metabolic sequelae, caused by exocrine pancreatic insufficiency, need to be promptly recognized and treated with an adequate enzyme supplementation. CONCLUSIONS There is strong evidence sustaining the necessity of proper perioperative metabolic and nutritional care into the management of patients undergoing major pancreatic surgery.

Abstract
PURPOSES To establish a scoring model for the risk of postoperative pancreatic fistula (POPF) following pancreatoduodenectomy (PD). METHODS PD Patients from 7 institutions in 2 independent sets: developmental (n = 457) and validation cohort (n = 152) were retrospectively enrolled and analyzed. Pancreatic Fibrosis (PF) and Pancreatic Steatosis (PS) were assessed by pathological examination of the pancreatic stump. RESULTS Stepwise univariate and multivariate analysis indicated that pancreatic duct diameter ≤ 3 mm, increased PS and decreased PF were independent risk factors for POPF and Clinically Relevant Postoperative Pancreatic Fistula (CR-POPF). Based on the relative weight and odds ratio of each factor in the POPF, a simplified scoring model was developed. And patients were stratified into high-risk group (22~28 points), medium-risk group (15~21 points) and low-risk group (8~14 points). The receiver operating characteristic curve demonstrated that the Area under the curve for the predictive model was 0.868 and 0.887 in the model design group and the external validation group. CONCLUSIONS This study establishes a simplified scoring model based on accurately and quantitatively measuring the PS, PF and pancreatic duct diameter. The scoring model accurately predicted the risk of POPF.

Abstract
Background In 2013, the fistula risk score (FRS) was developed to assess the risk of clinically relevant postoperative pancreatic fistula (CR‐POPF). In 2017, the alternative FRS (a‐FRS) was proposed. The purpose of this study was to validate the original FRS (o‐FRS) and a‐FRS for CR‐POPF in pancreaticoduodenectomy (PD). Methods From January 2007 to December 2016, 1,771 patients underwent PD for periampullary cancers. POPF was defined and classified according to the 2016 International Study Group for Pancreatic Fistula. All data were reviewed retrospectively. Results Pathologic diagnosis other than ductal adenocarcinoma (P < 0.001), pancreas duct diameter (P < 0.001), and body mass index (P < 0.001) were independent risk factors for CR‐POPF. Pancreatic texture (P = 0.534) and estimated blood loss (P = 0.827) were not associated with CR‐POPF. The CR‐POPF incidence increased with increasing o‐FRS score (P < 0.001), and also increased statistically significantly with increasing a‐FRS in the higher risk group (P < 0.001). However, the correlations differed. The area under the curve was 0.629 for o‐FRS and 0.622 for a‐FRS. Conclusions Both o‐FRS and a‐FRS might reflect CR‐POPF incidence, but some risk factors had no or low statistical significance. Further research is needed to revise the FRS.

Abstract
BACKGROUND The goal of our study was to evaluate the current approach in prediction of postoperative major complications after pancreaticoduodenectomy (PD), especially symptomatic pancreatic fistula (POPF), using parameters derived from computed tomography (CT). METHODS Patients after PD were prospectively collected in a database of the local department of surgery and all patients with CT scans available were assessed in this study. CT parameters were measured at the level of the intervertebral disc L3/L4 and consisted of the areas of the visceral adipose tissue (AVAT), the diameters of the pancreatic parenchyma (DPP) and the pancreatic duct (DPD), the areas of ventral abdominal wall muscle (AMVEN), psoas muscle (AMPSO), paraspinal muscle (AMSPI), total muscle (AMTOT), as well as the mean muscle attenuation (MA) and skeletal muscle index (SMI). Mann-Whitney-U Test for two independent samples and binary logistic regression were used for statistical analysis. RESULTS One hundred thirty-nine patients (55 females, 84 males) were included. DPD was 2.9 mm (Range 0.7-10.7) on median and more narrow in patients with complications equal to or greater stadium IIIb (p < 0.04) and severe POPF (p < 0.01). DPP median value was 17 (6.9-37.9) mm and there was no significant difference regarding major complications or POPF. AVAT showed a median value of 127.5 (14.5-473.0) cm2 and was significantly larger in patients with POPF (p < 0.01), but not in cases of major complications (p < 0.06). AMPSO, AMSPI, AMVEN and AMTOT showed no significant differences between major complications and POPF. MA was both lower in groups with major complications (p < 0.01) and POPF (p < 0.01). SMI failed to differentiate between patients with or without major complications or POPF. CONCLUSION Besides the known factors visceral obesity and narrowness of the pancreatic duct, the mean muscle attenuation can easily be examined on routine preoperative CT scans and seems to be promising parameter to predict postoperative complications and POPF.

Abstract
This study was designed to analyze the risk factors for postoperative pancreatic fistula (POPF) after pancreaticoduodenectomy (PD).Between September 2015 and August 2017, 170 successive patients underwent a radical PD in the Department of Pancreatic Surgery, Union Hospital, Wuhan. We carried out a retrospective study of these cases and the prospective conditions, which might be related to POPF, were examined with univariate and multivariate analysis. POPF was defined as a drain output of any measurable volume of fluid with an amylase level more than 3 times the upper limit of serum amylase activity on postoperative day 3, accompanied by a clinically relevant condition according to the 2016 update of the International Study Group for Pancreatic Surgery (ISGPS) definition. In our study, the POPF was just referred to as grade B and grade C pancreatic fistula in accordance with the ISGPS consensus, because the former grade A pancreatic fistula is now redefined as a biochemical leak, namely no-POPF, which has no clinical impact and needs no other special therapy.Pancreatic fistula occurred in 44 (25.9%) patients after PD, with a mean length of hospital stay of 24.98 ± 14.30 days. Thirty-six patients (21.2%) developed grade B pancreatic fistula, and 8 patients (4.7%) had grade C pancreatic fistula. Among patients with grade C pancreatic fistula, 4 patients died, 3 patients were operated on again, and 3 patients developed multiple organ failure.Univariate analysis showed a significantly important association between POPF and the following factors: pancreas texture (soft vs hard: 39.1% vs 10.3%, P < .0001) and fasting blood glucose level (<108.0 mg/dL vs ≥108.0 mg/dL: 32.5% vs 12.5%, P = .005). Multivariate logistic regression analysis identified 2 independent factors related to POPF: soft pancreas texture and fasting blood glucose level <108.0 mg/dL.A soft pancreas and a fasting blood glucose level of <108.0 mg/dL are risk factors for the development of a POPF.

Abstract
BACKGROUND Failure to rescue (FTR) is a quality-of-care indicator in pancreatic surgery, but may also identify patients who may not tolerate major postoperative complications despite being treated with best available care. Previous studies found that high visceral adipose tissue-to-skeletal muscle ratio is associated with poor outcomes following pancreaticoduodenectomy (PD). The aim of the study is to assess the impact of sarcopenic obesity on occurrence of FTR from major complications in cancer patients undergoing PD. METHODS Prospectively collected data from three high-volume hospitals were reviewed. Total abdominal muscle area (TAMA) and visceral fat area (VFA) were assessed at preoperative staging computed tomography scan. Sarcopenic obesity was defined as high VFA/TAMA ratio. FTR was defined as postoperative mortality following major complication. RESULTS 120 patients with major complications were included. FTR occurred in 23 (19.2%) patients. The "seminal" complications leading to FTR were pancreatic or biliary fistula-related sepsis (n = 14), postoperative pancreatic fistula (POPF)-related hemorrhage (n = 5), and duodenojejunal anastomosis leak-related sepsis (n = 1). On univariate analysis, older age [odds ratio (OR) 3.5, p = 0.034], American Society of Anesthesiologists (ASA) score 3+ (OR 4.2, p = 0.005), cardiovascular disease (OR 3.3, p = 0.013), low serum albumin (OR 2.6, p = 0.042), sarcopenic obesity (OR 4.2, p = 0.009), POPF (OR 3.1, p = 0.027), and cardiorespiratory complications (OR 3.7, p = 0.011) were significantly associated with FTR. On multivariate analysis, sarcopenic obesity [OR 5.7, 95% confidence interval (CI) 1.6-20.7, p = 0.008], ASA score 3+ (OR 4.1, 95% CI 1.2-14.3, p = 0.025), and pancreatic fistula (OR 3.2, 95% CI 1.0-10.2, p = 0.045) were independently associated with FTR. CONCLUSION Sarcopenic obesity, low preoperative physical status, and occurrence of pancreatic fistula are associated with significantly higher risk of FTR from major complications after PD.

Abstract
PURPOSE A thick pancreas has proven to be a conspicuous predictor of pancreatic fistula (PF) following distal pancreatectomy (DP) using staples. Other predictors for this serious surgical complication currently remain obscure. This study sought to identify novel predictors of PF following DP. METHODS One hundred and twenty-two patients were retrospectively assessed to determine the correlation between PF occurrence and the clinicopathological findings and radiologic data from preoperative computed tomography (CT). CT assessments included the thickness of the pancreas (TP) and pancreatic CT number (pancreatic index; PI), calculated by dividing the pancreatic CT by the splenic CT density. RESULTS Twenty-four patients (19.7%) developed a clinically relevant PF. TP was identified as an independent risk factor for PF in multivariate analyses (odds ratio 1.17; P = 0.0095). In subgroup analyses, a lower PI in a thick pancreas was a significant predictor of PF (P = 0.032). The combination of these two prediction parameters, known as the TP-to-PI ratio (TPIR), showed a significantly better prediction ability than TP alone (area under the receiver operating characteristic curve for the incidence of PF, TPIR 0.80 vs. TP 0.69; P = 0.037). CONCLUSION Combining the CT number with TP substantially improves the prediction ability for the incidence of PF following DP with staple use.

Abstract
OBJECTIVE Complication rates after pancreatic resections remain high despite improvement in perioperative management. The effects of body composition and the relationship among different body compartments on surgical morbidity are not comprehensively investigated. The aim of this study was to assess whether the evaluation of different body compartments and their relationship was associated with the development of major postoperative complications after pancreatoduodenectomy (PD) for cancer. METHODS We retrospectively analyzed 124 patients who underwent PD and had a staging computed tomography (CT) scan at our center. CT scan was used to measure abdominal skeletal muscle area and volume, as well as visceral fat area (VFA) and volume. The total abdominal muscle area (TAMA) was then normalized for height. The severity of complications was assessed. Univariate and multivariate analyses were performed to investigate correlations between the above variables and postoperative complications. The receiver operating characteristic curve methodology was used to investigate the predictive ability of each parameter. RESULTS Major complications occurred in 42 patients (33.9%). The prevalence of sarcopenia was 24.2%. Regression analyses revealed no correlation between abdominal muscular and adipose tissue areas. Univariate analysis showed that the depletion of muscle area normalized for height was not per se predictive of complications (P = 0.318). Multivariate logistic regression showed that the VFA/TAMA was the only determinant of major complications (odds ratio, 3.20; 95% confidence interval, 1.35-7.60; P = 0.008). The model predictive performance was 0.735 (area under the curve) with a sensitivity of 64.3% and a specificity of 74.4%. CONCLUSION Sarcopenic obesity is a strong predictor of major complications after PD for cancer.

Abstract
AIM To analyze the risk factors for pancreatic fistula after pancreaticoduodenectomy. METHODS We conducted a retrospective analysis of 539 successive cases of pancreaticoduodenectomy performed at our hospital from March 2012 to October 2015. Pancreatic fistula was diagnosed in strict accordance with the definition of pancreatic fistula from the International Study Group on Pancreatic Fistula. The risk factors for pancreatic fistula were analyzed by univariate analysis and multivariate logistic regression analysis. RESULTS A total of 269 (49.9%) cases of pancreatic fistula occurred after pancreaticoduodenectomy, including 71 (13.17%) cases of grade A pancreatic fistula, 178 (33.02%) cases of grade B, and 20 (3.71%) cases of grade C. Univariate analysis showed no significant correlation between postoperative pancreatic fistula (POPF) and the following factors: age, hypertension, alcohol consumption, smoking, history of upper abdominal surgery, preoperative jaundice management, preoperative bilirubin, preoperative albumin, pancreatic duct drainage, intraoperative blood loss, operative time, intraoperative blood transfusion, Braun anastomosis, and pancreaticoduodenectomy (with or without pylorus preservation). Conversely, a significant correlation was observed between POPF and the following factors: gender (male vs female: 54.23% vs 42.35%, P = 0.008), diabetes (non-diabetic vs diabetic: 51.61% vs 39.19%, P = 0.047), body mass index (BMI) (≤ 25 vs > 25: 46.94% vs 57.82%, P = 0.024), blood glucose level (≤ 6.0 mmol/L vs > 6.0 mmol/L: 54.75% vs 41.14%, P = 0.002), pancreaticojejunal anastomosis technique (pancreatic duct-jejunum double-layer mucosa-to-mucosa pancreaticojejunal anastomosis vs pancreatic-jejunum single-layer mucosa-to-mucosa anastomosis: 57.54% vs 35.46%, P = 0.000), diameter of the pancreatic duct (≤ 3 mm vs > 3 mm: 57.81% vs 38.36%, P = 0.000), and pancreatic texture (soft vs hard: 56.72% vs 29.93%, P = 0.000). Multivariate logistic regression analysis showed that gender (male), BMI > 25, pancreatic duct-jejunum double-layer mucosa-to-mucosa pancreaticojejunal anastomosis, pancreatic duct diameter ≤ 3 mm, and soft pancreas were risk factors for pancreatic fistula after pancreaticoduodenectomy. CONCLUSION Gender (male), BMI > 25, pancreatic duct-jejunum double-layer mucosa-to-mucosa pancreaticojejunal anastomosis, pancreatic duct diameter ≤ 3 mm, and soft pancreas were risk factors for pancreatic fistula after pancreaticoduodenectomy.
