Abstract
BACKGROUND Clinically relevant postoperative pancreatic fistula (CR-POPF) is a common and troublesome complication after pancreatoduodenectomy (PD). We conducted a systematic review and meta-analysis to identify the risk factors of CR-POPF after PD. METHODS We searched PubMed, EMBASE, and Cochrane Library databases for studies related to risk factors of CR-POPF after PD. Odds ratios (ORs) with corresponding 95% confidence intervals (CIs) were extracted from the included studies, then a meta-analysis was conducted. If necessary, sensitivity analysis would be performed by changing the effect model or excluding 1 study at a time. Publication bias was assessed by funnel plot and Begg test and Egger test. RESULTS A total of 27 studies with 24,740 patients were included, and CR-POPF occurred in 3843 patients (incidence = 17%, 95% CI: 16%-19%). Male (OR = 1.56, 95% CI: 1.42-1.70), body mass index >25 kg/m2 (OR = 1.98, 95% CI: 1.23-3.18), pancreatic duct diameter <3 mm (OR = 1.87, 95% CI: 1.66-2.12), soft pancreatic texture (OR = 3.49, 95% CI: 2.61-4.67), and blood transfusion (OR = 3.10, 95% CI: 2.01-4.77) can significantly increase the risk of CR-POPF. Pancreatic adenocarcinoma (OR = 0.54, 95% CI: 0.47-0.61), vascular resection (OR = 0.57, 95% CI: 0.39-0.83), and preoperative chemoradiotherapy (OR = 0.68, 95% CI: 0.57-0.81) can significantly decrease the factor of CR-POPF. Diabetes mellitus was not statistically associated with CR-POPF (OR = 0.66, 95% CI: 0.40-1.08). However, the analysis of body mass index, pancreatic texture, and diabetes mellitus had a high heterogeneity, then sensitivity analysis was performed, and the result after sensitivity analysis showed diabetes mellitus can significantly decrease the risk of CR-POPF. There was no significant publication bias in this meta-analysis. CONCLUSIONS The current review assessed the effects of different factors on CR-POPF. This can provide a basis for the prevention and management of CR-POPF. Effective interventions targeting the above risk factors should be investigated in future studies for decreasing the occurrence of CR-POPF.

Effect of preoperative asymptomatic renal dysfunction on the clinical course after colectomy for colon cancer. Surg Today 2021; 52:106-113. [PMID: 34455492 DOI: 10.1007/s00595-021-02363-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2021] [Accepted: 04/19/2021] [Indexed: 12/24/2022]
Abstract
PURPOSE To evaluate the effect of mild renal dysfunction on the clinical course after colectomy in patients with colon cancer. METHODS The subjects of this retrospective study were 263 patients who underwent surgical resection for colon cancer at our hospital between 2011 and 2015. Renal function was assessed based on preoperative estimated glomerular filtration rate (eGFR) values. Patients were divided into groups based on their eGFR value of 55 ml/min/1.73 m2. The Mann-Whitney U test, chi-square or Fisher exact test, and log-rank test were used in the data analysis. RESULTS There were 59 patients (22.4%) in the low eGFR group and 204 patients in the normal eGFR group. There were differences between the groups in age, comorbidities, and the levels of hemoglobin, albumin, and serum creatinine. The overall postoperative complication rate, frequency of severe complications, and length of stay were significantly higher in the low eGFR group than in the normal eGFR group. Multivariate analysis revealed that low eGFR was the only independent risk factor for severe complications (Clavien-Dindo classification III/IV). There were no differences in survival between the groups. CONCLUSION Preoperative asymptomatic renal dysfunction may be correlated with the development of postoperative complications and a possible significant risk factor for severe complications after colon cancer surgery.

Abstract
BACKGROUND Clinically relevant postoperative pancreatic fistula (CR-POPF) remains a severe and challenging complication of pancreaticoduodenectomy (PD). This study aimed to establish a novel postoperative nomogram-based diagnostic model for the early detection of CR-POPF in patients subjected to PD. METHODS Consecutive patients who underwent PD in Zhongshan Hospital, Fudan University from December 2018 to October 2020 were retrospectively enrolled. Univariate and multivariate logistic regression analyses were performed to identify independent risk factors for CR-POPF. Then, a novel predictive nomogram was established accordingly. RESULTS Among the consecutive 176 patients who underwent PD, 37 (21.1%) patients developed CR-POPF. Through univariate and multivariate analyses, the drain amylase (P = 0.002), serum creatinine (P = 0.009), and serum C reactive protein (P = 0.045) at postoperative day 1 (POD1) as well as the neutrophil count (P = 0.025) and temperature (P = 0.025) at POD3 were identified as independent risk factors for CR-POPF. Based on this, a novel predictive nomogram containing these factors was constructed to predict the probability of CR-POPF after PD. The formulated nomogram showed better performance to detect CR-POPF after PD with a sensitivity of 0.784, specificity of 0.770, positive predictive value of 0.475, and negative predictive value of 0.930 when compared to other predictors. In addition, the predictive value of the nomogram was assessed by a concordance index of 0.814 (95% CI, 0.736-0.892), which was significantly higher than indicators alone. This was further validated and depicted by decision curve analysis and clinical impact curve. CONCLUSION This study established a diagnostic nomogram of postoperative objective parameters that can predict the development of CR-POPF after PD with a good discriminative ability and predictive accuracy.

BMC Surg 2021; 21:7. [PMID: 33397337 PMCID: PMC7784027 DOI: 10.1186/s12893-020-00968-5] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2020] [Accepted: 11/17/2020] [Indexed: 02/08/2023] Open
Abstract
Background With the recent emerge of dynamic prediction model on the use of diabetes, cardiovascular diseases and renal failure, and its advantage of providing timely predicted results according to the fluctuation of the condition of the patients, we aim to develop a dynamic prediction model with its corresponding risk assessment chart for clinically relevant postoperative pancreatic fistula after laparoscopic pancreaticoduodenectomy by combining baseline factors and postoperative time-relevant drainage fluid amylase level and C-reactive protein-to-albumin ratio. Methods We collected data of 251 patients undergoing LPD at West China Hospital of Sichuan University from January 2016 to April 2019. We extracted preoperative and intraoperative baseline factors and time-window of postoperative drainage fluid amylase and C-reactive protein-to-albumin ratio relevant to clinically relevant pancreatic fistula by performing univariate and multivariate analyses, developing a time-relevant logistic model with the evaluation of its discrimination ability. We also established a risk assessment chart in each time-point. Results The proportion of the patients who developed clinically relevant postoperative pancreatic fistula after laparoscopic pancreaticoduodenectomy was 7.6% (19/251); preoperative albumin and creatine levels, as well as drainage fluid amylase and C-reactive protein-to-albumin ratio on postoperative days 2, 3, and 5, were the independent risk factors for clinically relevant postoperative pancreatic fistula. The cut-off points of the prediction value of each time-relevant logistic model were 14.0% (sensitivity: 81.9%, specificity: 86.5%), 8.3% (sensitivity: 85.7%, specificity: 79.1%), and 7.4% (sensitivity: 76.9%, specificity: 85.9%) on postoperative days 2, 3, and 5, respectively, the area under the receiver operating characteristic curve was 0.866 (95% CI 0.737–0.996), 0.896 (95% CI 0.814–0.978), and 0.888 (95% CI 0.806–0.971), respectively. Conclusions The dynamic prediction model for clinically relevant postoperative pancreatic fistula has a good to very good discriminative ability and predictive accuracy. Patients whose predictive values were above 14.0%, 8.3%, and 7.5% on postoperative days 2, 3, and 5 would be very likely to develop clinically relevant postoperative pancreatic fistula after laparoscopic pancreaticoduodenectomy.

Abstract
PURPOSE Recent large-scale clinical studies have shown that preoperative renal insufficiency is associated with an increased risk of postoperative complications after esophagectomy; however, it remains unclear whether asymptomatic renal dysfunction affects the postoperative course after esophagectomy. METHODS The subjects of this retrospective study were 177 patients who underwent esophagectomy between May, 2009 and December, 2018. Renal function was evaluated based on the pretreatment estimated glomerular filtration rate (eGFR). Patients were divided into two groups according to the eGFR cut-off value of 55 ml/min per 1.73 m2. RESULTS There were 17 patients in the low eGFR group and 160 patients in the normal group eGFR group. The rate of severe complications was significantly higher in the low eGFR than in the normal eGFR group. A low eGFR was the only significant complication risk factor identified; however, there were no marked differences in mortality or survival between the low and normal eGFR groups. CONCLUSION Our findings demonstrate that pretreatment asymptomatic renal dysfunction may be a significant risk factor for severe morbidity after esophagectomy.

Abstract
Surgical resection represents the only potentially curative therapy for patients with pancreatic adenocarcinoma (PDAC), an aggressive malignancy with a very limited 5-year survival rate. However, even after complete tumor resection, many patients are still facing an unfavorable prognosis underlining the need for better preoperative stratification algorithms. Here, we explored the role of the secreted glycoprotein soluble urokinase plasminogen activator receptor (suPAR) as a novel circulating biomarker for patients undergoing resection of PDAC. Serum levels of suPAR were measured by enzyme-linked immunosorbent assay (ELISA) in an exploratory as well as a validation cohort comprising a total of 127 PDAC patients and 75 healthy controls. Correlating with a cytoplasmic immunohistochemical expression of uPAR in PDAC tumor cells, serum levels of suPAR were significantly elevated in PDAC patients compared to healthy controls and patient with PDAC precursor lesions. Importantly, patients with high preoperative suPAR levels above a calculated cutoff value of 5.956 ng/ml showed a significantly reduced overall survival after tumor resection. The prognostic role of suPAR was further corroborated by uni- and multivariate Cox-regression analyses including parameters of systemic inflammation, liver and kidney function as well as clinico-pathological patients’ characteristics. Moreover, high baseline suPAR levels identified those patients particularly susceptible to acute kidney injury and surgical complications after surgery. In conclusion, our data suggest that circulating suPAR represents a novel prognostic marker in PDAC patients undergoing tumor resection that might be a useful addition to existing preoperative stratification algorithms for identifying patients that particularly benefit from extended tumor resection.

Abstract
To assess the efficiency of several previous scoring systems in the prediction of postoperative complications of pancreatoduodenectomy (PCPD) and to explore a new simplified scoring system for PCPD prediction.All 183 consecutive patients scheduled for PD from 2010 to 2017 in the Second Affiliated Hospital of Chongqing Medical University were collected retrospectively. The area under the curve (AUC) for the prediction of PCPD was calculated for POSSUM, E-PASS, APACHE-II, and APACHE-III, which were used to test the efficiency of PCPD prediction. The independent risk factors included in the new scoring system were determined by univariate analysis and a logistic regression model. Next, the prediction efficiency was validated.The results of the univariate analysis showed that such variables as male sex, weight, WBC, serum sodium, arterial pH, postoperative 24 hours urine output, and operation time were influence factors for postoperative complications (P <.05). Arterial pH, serum sodium, postoperative 24 hours urine output, and WBC were independent risk factors of postoperative complications based on the logistic regression analysis (P <.05). The AUC of the novel scoring system for PCPD prediction was 85.4%.The proposed scoring system might be a more effective tool for predicting PCPD compared with previous multipurpose scoring systems.

HPB (Oxford) 2018; 20:992-1003. [PMID: 29807807 DOI: 10.1016/j.hpb.2018.04.003] [Citation(s) in RCA: 84] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/14/2017] [Revised: 03/09/2018] [Accepted: 04/29/2018] [Indexed: 02/07/2023]
Abstract
BACKGROUND In 2016, the International Study Group of Pancreatic Fistula (ISGPS) proposed an updated definition for postoperative pancreatic fistula (POPF). Pancreas texture (PT) is an established risk factor of POPF. The definition of soft vs. hard texture, however, remains elusive. METHODS A systematic search was performed to identify PT definitions and a meta-analysis linking POPF to PT using the updated ISGPS definition. RESULTS 122 studies including 22 376 patients were identified. Definition criteria for PT varied among studies and most classified PT in hard and soft based on intraoperative subjective assessment. The total POPF rate (pooled grades B and C) after pancreatoduodenectomy was 14.5% (n = 10 395) and 15.5% (n = 3767) after distal pancreatectomy. In pancreatoduodenectomy, POPF rate was higher in soft compared to hard pancreas (RR, 4.4, 3.3 to 6.1; p < 0.001; n = 6393), where PT grouped as soft and hard. No data were available for intermediate PT. CONCLUSION The reported POPF rates may be used in planning future prospective studies. A widely accepted definition of PT is lacking and a correlation with the risk of POPF is based on subjective evaluation, which is still acceptable. Classification of PT into 2-groups is more reasonable than classification into 3-groups.

Increased Risk of Complications After Pancreatoduodenectomy in Uninephrectomized Patients. Int Surg 2018. [DOI: 10.9738/intsurg-d-18-00022.1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/17/2022] Open
Abstract
Objective:
The study objective is to investigate the impact of unilateral nephrectomy on the complications after pancreatoduodenectomy (PD).
Summary of background data:
Preoperative renal insufficiency is a risk factor for postoperative complications and mortality after various types of surgery. However, the specific postoperative risks in uninephrectomized (UN) patients are largely unknown.
Methods:
Between January 2010 and June 2014, a total of 177 patients underwent PD at the Department of Surgery, Nara Medical University. Among them, 7 patients (4.0%) were UN. We retrospectively evaluated the influence of the UN status on the postoperative complications.
Results:
The rate of acute kidney injury in the UN group was significantly higher than that in the control group (28.6% versus 1.2%; P = 0.017). In addition, the rates of surgical site infection of the organ/space (57.1% versus 9.0%; P = 0.006) and sepsis (42.9% versus 3.5%; P = 0.003) in UN group were significantly higher. Even on a reanalysis of only patients with soft pancreas, the significance remained.
Conclusions:
The UN status has a significant impact on the rate of morbidities, such as acute kidney injury and various infectious complications, including surgical site infections of organ/space, sepsis, and cholangitis after PD. Appropriate intervention should be implemented to decrease the morbidity rate for UN patients.

Abstract
BACKGROUND/OBJECTIVES Pancreatic fistulas are one of the most frequent morbidities after pancreaticoduodenectomy. Several reports have suggested a relationship between bacterial infections and postoperative pancreatic fistulas, although details of the mechanisms involved in hemorrhage in association with the fistulas have not been elucidated. This study retrospectively examined the relationship between positive drainage culture and hemorrhage associated with pancreatic fistulas after pancreaticoduodenectomy. METHODS From January 2012 to December 2015, 142 consecutive patients underwent pancreaticoduodenectomy at our institution. We retrospectively reviewed the patients' demographic data, perioperative laboratory data, and drainage culture results. RESULTS Twenty-four (17%) patients had clinically relevant postoperative pancreatic fistulas, whereas thirty-four (24%) patients experienced positive drainage culture. Multivariable analysis revealed that positive drainage culture was independently associated with clinically relevant postoperative pancreatic fistulas (odds ratio, 18.1; 95% confidence interval, 5.5-72.2; P < 0.001). Additionally, the prevalence of Candida albicans in the lavage of eight patients significantly correlated with hemorrhage associated with pancreatic fistulas (odds ratio, 43.5; 95% confidence interval, 6.2-513.3; P < 0.001). Seventy-five percent (6/8) of these patients suffered potentially lethal hemorrhagic complications and needed intervention. CONCLUSIONS A positive abdominal drainage culture is associated with the development of pancreatic fistulas. Moreover, the presence of Candida albicans in drainage fluid may be a risk factor for hemorrhagic complications.
