Abstract
Background In this study, we aimed to determine the association between postoperative hyperamylasemia (POH) and clinically relevant postoperative pancreatic fistula (CR-POPF) after pancreatoduodenectomy (PD). Methodology A prospective observational study of 140 consecutive PDs between March 2020 and March 2022 was conducted. POH was defined as an elevation in serum pancreatic amylase levels above the institutional upper limit of normal on postoperative day (POD) 1 (>100 U/L). CR-POPF was defined as the International Study Group of Pancreatic Surgery Grade B or C POPF. The primary outcome was the rate of CR-POPF in the study population. The trial was prospectively registered with Clinicaltrials.gov (NCT04514198). Results In our study, 93 (66.42%) patients had POH (serum amylase >100 U/L). CR-POPF developed in 48 (34.28%) patients: 40 type B and 8 type C. CR-POPF rate was 43.01% (40/93) in patients with POH compared to 17.02% (8/47) in patients without POH (p = 0.0022). Patients with POH had a mean serum amylase of 422.7 ± 358.21 U/L on POD1 compared to 47.2 ± 20.19 U/L in those without POH (p < 0.001). Serum amylase >100 U/L on POD1 was strongly associated with developing CR-POPF (odds ratio = 3.71; 95% confidence interval = 1.31-10.37) on logistic regression, with a sensitivity and specificity of 83.3% and 42.4%, respectively. Blood loss >350 mL, pancreatic duct size <3 mm, and elevated POD1 serum amylase >100 U/L were predictive of CR-POPF on multivariate analysis (p < 0.001). Conclusions An elevated serum amylase on POD1 may help identify patients at risk for developing POPF following PD.

Risk Factors of Postoperative Acute Pancreatitis and Its Impact on the Postoperative Course after Pancreaticoduodenectomy-10 Years of Single-Center Experience. Life (Basel) 2023; 13:2344. [PMID: 38137945 PMCID: PMC10744948 DOI: 10.3390/life13122344] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2023] [Revised: 11/30/2023] [Accepted: 12/13/2023] [Indexed: 12/24/2023] Open
Abstract
BACKGROUND Clinically relevant acute postoperative pancreatitis (CR-PPAP) after pancreaticoduodenectomy (PD) is a complication that may lead to the development of local and systemic consequences. The study aimed to identify risk factors for CR-PPAP and assess the impact of CR-PPAP on the postoperative course after PD. METHODS The study retrospectively analyzed data from 428 consecutive patients who underwent PD at a single center between January 2013 and December 2022. The presence of increased amylase activity in plasma, above the upper limit of normal 48 h after surgery, was checked. CR-PPAP was diagnosed when accompanied by disturbing radiological features and/or symptoms requiring treatment. We investigated the relationship between the occurrence of CR-PPAP and the development of postoperative complications after PD, and possible predictors of CR-PPAP. RESULTS The postoperative follow-up period was 90 days. Of the 428 patients, 18.2% (n = 78) had CR-PPAP. It was associated with increased rates of CR-POPF, delayed gastric emptying, occurrence of intra-abdominal collections, postoperative hemorrhage, peritonitis, and septic shock. Patients who developed CR-PPAP were more often reoperated (37.17% vs. 6.9%, p < 0.0001)) and had increased postoperative mortality (14.1% vs. 5.74%, p < 0.0001). Soft pancreatic parenchyma, intraoperative blood loss, small diameter of the pancreatic duct, and diagnosis of adenocarcinoma papillae Vateri were independent risk factors for CR-PPAP and showed the best performance in predicting CR-PPAP. CONCLUSIONS CR-PPAP is associated with an increased incidence of postoperative complications after PD, worse treatment outcomes, and an increased risk of reoperation and mortality. Pancreatic consistency, intraoperative blood loss, width of the duct of Wirsung, and histopathological diagnosis can be used to assess the risk of CR-PPAP. Amylase activity 48 h after surgery > 161 U/L is highly specific in the diagnosis of CR-PPAP.

Abstract
PURPOSE Prevention and management of postoperative pancreatic fistula (POPF) after pancreatic resections is still an unresolved issue. Continuous irrigation of the peripancreatic area is frequently used to treat necrotizing pancreatitis, but its use after elective pancreatic surgery is not well-known. With this systematic review, we sought to evaluate the current knowledge and expertise regarding the use of continuous irrigation in the surgical area to prevent or treat POPF after elective pancreatic resections. METHODS A systematic search of the literature was conducted according to the PRISMA 2020 guidelines, screening the databases of Pubmed, Scopus, Web of Science, and Ovid MEDLINE. Because of the heterogeneity of the included articles, a statistical inference could not be performed and the literature was reviewed only descriptively. The study was pre-registered online (OSF Registry). RESULTS Nine studies were included. Three studies provided data regarding the prophylactic use of continuous irrigation after distal and limited pancreatectomies. Here, patients after irrigation showed a lower rate of clinically relevant POPF, related complications, lengths of stay, and mortality. Six other papers reported the use of local lavage to treat clinically relevant POPF and subsequent fluid collections, with successful outcomes. CONCLUSION In the current literature, only a few publications are focused on the use of continuous irrigation after pancreatic resection to prevent or manage POPF. The included studies showed promising results, and this technique may be useful in patients at high risk of POPF. Further investigations and randomized trials are needed.

Abstract
BACKGROUND Abdominal surgery for gastrointestinal malignancies has a significant impact on patients' health-related quality of life. However, there is so far no patient-reported outcome measures (PROM) in the immediate postoperative period to detect the perioperative symptom burden and patients' needs which may precede occult and severe complications. The aim of the study was to create a conceptual framework for the development of a PROM to measure perioperative symptom burden in abdominal cancer patients. METHODS This mixed method study was performed between March 2021, and July 2021 as part of a multiphase approach to develop a new PROM. A systematic review of the literature was performed health domains were identified. The relevance of the health domains was assessed in a two-round Delphi study with clinical experts. Qualitative interviews were performed in patients who underwent abdominal surgery for cancer. RESULTS The systematic literature review yielded 12 different PROM with 168 items and 55 health domains. The most common health domains involved the "digestive system" and "pain". In total, 30 patients (median age 66 years, 20 men [60%]) were included for qualitative patient interviews. Of 16 health domains identified by the Delphi study, a total 15 health domains were confirmed during patients' interviews. The final conceptual framework included 20 health domains. CONCLUSION This study provides the essential groundwork to develop and validate a new PROM for the immediate postoperative period of patients undergoing abdominal surgery for cancer.

Abstract
Background Postoperative acute pancreatitis (POAP) is a specific complication after pancreatectomy. The acute inflammatory response of the residual pancreas may affect the healing of pancreatoenteric anastomoses, leading to postoperative pancreatic fistulas (POPFs), abdominal infections, and even progressive systemic reactions, conditions that negatively affect patients' prognoses and can cause death. However, to the best of our knowledge, no systematic reviews or meta-analytic studies have assessed the incidence and risk factors of POAP after pancreaticoduodenectomy (PD). Method We searched PubMed, Web of Science, Embase, and Cochrane Library databases for relevant literature describing the outcomes of POAP after PD until November 25, 2022, and we used the Newcastle-Ottawa Scale to assess the quality of the studies. Next, we pooled the incidence of POAP and the odds ratios (ORs) and 95% confidence intervals (CIs) of the risk factors using a random-effect meta-analysis. I2 tests were used to assess heterogeneity between the studies. Results We analyzed data from 7,164 patients after PD from 23 articles that met the inclusion criteria for this study. The subgroup results of the meta-analysis by different POAP diagnostic criteria showed that the incidences of POAP were 15% (95% CI, 5-38) in the International Study Group for Pancreatic Surgery group, 51% (95% CI, 42-60) in the Connor group, 7% (95% CI, 2-24) in the Atlanta group, and 5% (95% CI, 2-14) in the unclear group. Being a woman [OR (1.37, 95% CI, 1.06-1.77)] or having a soft pancreatic texture [OR (2.56, 95% CI, 1.70-3.86)] were risk factors of POAP after PD. Conclusion The results showed that POAP was common after PD, and its incidence varied widely according to different definitions. Large-scale reports are still needed, and surgeons should remain aware of this complication. Systematic Review Registration identifier: CRD42022375124.

Abstract
PURPOSE We aimed to analyze the predictive value of hyperamylasemia after pancreatectomy for morbidity and for the decision to perform rescue completion pancreatectomy (CP) in a retrospective cohort study. METHODS Data were extracted from a retrospective clinical database. Postoperative hyperamylasemia (POH) and postoperative hyperlipasemia (POHL) were defined by values greater than those accepted as the upper limit at our institution on postoperative day 1 (POD1). The endpoints of the study were the association of POH with postoperative morbidity and the possible predictors for postpancreatectomy acute pancreatitis (PPAP) and severe complications such as the necessity for rescue CP. RESULTS We analyzed 437 patients who underwent pancreaticoduodenectomy over a period of 7 years. Among them, 219 (52.3%) patients had POH and 200 (47.7%) had normal postoperative amylase (non-POH) levels. A soft pancreatic texture (odds ratio [OR] 3.86) and POH on POD1 (OR 8.2) were independent predictors of postoperative pancreatic fistula (POPF), and POH on POD1 (OR 6.38) was an independent predictor of rescue CP. The clinically relevant POPF (49.5% vs. 11.4%, p < 0.001), intraabdominal abscess (38.3% vs. 15.3%, p < 0.001), postoperative hemorrhage (22.8% vs. 5.1%, p < 0.001), major complications (Clavien-Dindo classification > 2) (52.5% vs. 25.6%, p < 0.001), and CP (13% vs. 1.8%, p < 0.001) occurred significantly more often in the POH group than in the non-POH group. CONCLUSION Although POH on POD1 occurs frequently, in addition to other risk factors, it has a predictive value for the development of postoperative morbidity associated with PPAP and CP.

Abstract
BACKGROUND The diagnosis of postoperative or post-pancreatectomy acute pancreatitis (PPAP) is controversial. In 2021, the International Study Group of Pancreatic Surgery (ISGPS) published the first unifying definition and grading system for PPAP. This study sought to validate recent consensus criteria, using a cohort of patients undergoing pancreaticoduodenectomy (PD) in a high-volume pancreaticobiliary specialty unit. METHODS All consecutive patients undergoing PD at a tertiary referral centre between January 2016 and December 2021 were retrospectively reviewed. Patients with serum amylase recorded within 48h from surgery were included for analysis. Postoperative data were extracted and evaluated against the ISGPS criteria, including the presence of postoperative hyperamylasaemia, radiologic features consistent with acute pancreatitis, and clinical deterioration. RESULTS A total of 82 patients were evaluated. The overall incidence of PPAP was 32% (26/82) in this cohort, of which 3/26 demonstrated postoperative hyperamylasaemia and 23/26 had clinically relevant PPAP (Grade B or C) when correlated radiologic and clinical criteria. CONCLUSIONS This study is among the first to apply the recently published consensus criteria for PPAP diagnosis and grading to clinical data. While the results support their utility in establishing PPAP as a distinct post-pancreatectomy complication, there remains a need for future large-scale validation studies.

Abstract
BACKGROUND Post-pancreatectomy acute pancreatitis (PPAP) is a newly described clinical entity defined as elevated serum amylase sustained ≥ 48 h postoperatively, radiological findings consistent with acute pancreatitis, and associated clinically relevant features. This study aimed to investigate the incidence of PPAP and the rate of major complications after pancreatoduodenectomy (PD) in patients with only transiently elevated serum amylase. METHODS A retrospective single-center observational study was conducted including consecutive patients ≥ 18 years of age undergoing PD at Karolinska University Hospital, between 2008 and 2020. Serum amylase on postoperative day (POD) 1 and 2 and records from computer tomography were analyzed and correlated with postoperative major complications by logistic regressions. RESULTS Of some 1078 patients that underwent PD, 284 exhibited sustained elevated serum amylase (according to PPAP criteria) and 183 transiently elevated serum amylase on either POD1 or POD2. Of the patients with sustained elevated levels, 43% (n = 123) developed major complications, but only 6.3% (n = 18) showed findings consistent with acute pancreatitis on imaging. Of the 183 cases that exhibited only transiently elevated serum amylase on either POD1 or POD2, 32% (n = 58) developed major complications. CONCLUSION Sustained hyperamylasemia was observed in 26% of patients after PD, and an additional 17% of patients had a transient elevation of serum amylase postoperatively. Acute pancreatitis after PD may be underdiagnosed, partly by overlooking transiently elevated serum amylase and partly by requiring imaging that potentially fails to recognize mild but complication-prone acute pancreatitis.

Abstract
OBJECTIVE To characterize early postoperative serum pancreatic amylase (spAMY) trends after pancreatic resections. SUMMARY BACKGROUND DATA A postoperative spAMY elevation is a common finding but uncertainties remain about its meaning and prognostic implications. METHODS Analysis of patients who consecutively underwent pancreatectomy from 2016 to 2019. spAMY activity was assessed from postoperative day (POD) 0 to 3. Different patterns of spAMY have been identified based on the spAMY standard range (10-52 U/l). RESULTS Three patterns were identified: (#1) spAMY values always < the lower limit of normal/within the reference range /a single increase in spAMY > upper limit of normal at any POD; (#2) Sustained increase in spAMY activity on POD 0 + 1; (#3) Sustained increase in spAMY activity including POD 1 + 2. Shifting through spAMY patterns was associated with increase morbidity (21% in #1 to 68% in #3 at POD 7; log rank < 0.001). Almost all severe complications (at least Clavien-Dindo ≥3) occurred in patients with pattern #3 (15% vs 3% vs 5% in #1 and #2 at POD 7, P = 0.006), without difference considering >3-times or >the spAMY normal limit ( P = 0.85). POPF (9% in #1 vs 48% in #3, P < 0.001) progressively increased across patterns. Pre-operative diabetes (OR 0.19), neoadjuvant therapy (OR 0.22), pancreatic texture (OR 8.8), duct size (OR 0.78), and final histology (OR 2.2) were independent predictors of pattern #3. CONCLUSIONS A sustained increase in spAMY activity including POD 1 + 2 (#3) represents an early postoperative predictor of overall and severe early morbidity. An early and dynamic evaluation of spAMY could crucially impact the subsequent clinical course with relevant prognostic implications.

[PMID: 35945100 DOI: 10.1016/j.pan.2022.07.012] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/27/2022] [Revised: 07/11/2022] [Accepted: 07/24/2022] [Indexed: 12/11/2022]
Abstract
BACKGROUND Postoperative pancreatic fistula (POPF) remains a major complication after distal pancreatectomy (DP) with a significant impact on patients' quality of life. There is limited evidence that preservation of the spleen reduces the risk of POPF. Therefore, we aimed to investigate the impact of splenectomy on perioperative outcome. METHODS Data from patients who underwent DP for malignant and benign disease at our institution between 2004 and 2021 were reviewed. Patients were grouped according to spleen preservation (SP-DP) and splenectomy (DPS). Intraoperative parameters and postoperative outcomes were compared between groups. Univariable and multivariable analyses were used to investigate factors that influence the occurrence of clinically relevant (cr)POPF. RESULTS A total of 199 patients were included, of whom 61 (30.7%) patients underwent SP-DP. Patients who underwent SP-DP had a significantly lower rate of crPOPF (p = 0.022), shorter hospital stay (p = 0.003), and less readmissions (p = 0.012). On multivariate analysis, obesity (OR 2.88, p = 0.021), benign lesions (OR 2.35, p = 0.018), postoperative acute pancreatitis (OR 2.53, p = 0.028), and splenectomy (OR 2.83, p = 0.011) were independent risk factors associated with the onset of crPOPF. DISCUSSION Preservation of the spleen reduces the risk of crPOPF in patients undergoing distal pancreatectomy for benign and malignant disease.

Abstract
Clinically relevant postoperative pancreatic fistula (CR-POPF) has continued to compromise patient recovery post-pancreatectomy despite decades of research seeking to improve risk prediction and diagnosis. The current diagnostic criteria for CR-POPF requires elevated drain fluid amylase to present alongside POPF-related complications including infection, haemorrhage and organ failure. These worrying sequelae necessitate earlier and easily obtainable biomarkers capable of reflecting evolving CR-POPF. Drain fluid has recently emerged as a promising source of biomarkers as it is derived from the pancreas and hence, capable of reflecting its postoperative condition. The present review aims to summarise the current knowledge of CR-POPF drain fluid biomarkers and identify gaps in the field to invigorate future research in this critical area of clinical need. These findings may provide robust diagnostic alternatives for CR-POPF and hence, to clarify their clinical utility require further reports detailing their diagnostic and/or predictive accuracy.

Abstract
OBJECTIVES Patient characteristics with postoperative acute necrotizing pancreatitis and completion pancreatectomy (CP) after pancreaticoduodenectomy (PD) remain unclear. METHODS Data from all patients who underwent a PD with need for CP (January 2011-December 2019) at a German University Hospital were analyzed regarding the indications and timing of CP, laboratory and histopathological findings, and overall outcome. RESULTS Six hundred twelve patients underwent PD, 33 (5.4%) of them needed a CP. Indications were grade C pancreatic fistula with or without biliary leak (46% and 12%), biliary leak (6%), and hemorrhage due to pancreatic fistula (36%). Eight patients (24%) underwent CP within 3 days after PD. These fulminant courses ("pancreatic apoplexy") were accompanied by significantly higher levels of lactate dehydrogenase, C-reactive protein, serum amylase, serum lipase, drain amylase, and drain lipase compared with patients with CP after the third day. Pancreatic apoplexy was histologically associated with higher rates of pancreatic necrosis (P = 0.044) and hemorrhage (P = 0.001). A trend toward higher mortality was observed (75% vs 36%, P = 0.058). CONCLUSIONS Pancreatic apoplexy, defined as fulminant necrotizing pancreatitis after PD leading to CP within 3 days, is associated with characteristic laboratory and histopathological findings and a trend to higher mortality.

Abstract
BACKGROUND Increased postoperative serum amylase has been recently reported to be associated with increased postoperative morbidity, but studies on postoperative serum lipase are limited. The aim of this study was to evaluate the value of postoperative serum lipase in predicting clinically relevant postoperative pancreatic fistula (CR-POPF) after pancreaticoduodenectomy (PD). METHOD A retrospective analysis was performed on 212 patients who underwent PD from September 2018 and March 2021, focusing on the association between postoperative day (POD) 1 serum lipase and CR-POPF. RESULTS Overall, 108 (50.9%) patients had elevated serum lipase levels (>68 U/L) on POD 1. Patients with elevated serum lipase exhibited a significantly higher incidence of CR-POPF (37.0% vs. 6.7%, p < 0.001). Receiver operating characteristic (ROC) analyses showed improved diagnostic accuracy for POD 1 serum lipase compared with POD 1 serum amylase in predicting CR-POPF (AUC: 0.801 vs. 0.745, p = 0.029). Elevated serum lipase on POD 1 and elevated serum CRP on POD 3 were identified as independent predictors of CR-POPF. A simple early postoperative model, consisting of POD 1 serum lipase levels and POD 3 serum CRP levels, showed good discrimination (AUC 0.76, 95% CI 0.69-0.83) to identify the onset of CR-POPF. CONCLUSION Serum lipase on POD 1 outperformed serum amylase on POD 1 in predicting CR-POPF after PD. The combination of POD 1 serum lipase and POD 3 serum CRP provides a reliable predicting model for CR-POPF.

Abstract
BACKGROUND The clinical importance of postoperative hyperamylasemia (POHA) grade is unknown. Our objectives were to evaluate the association of POHA grade with clinically relevant postoperative pancreatic fistula (CR-POPF) and compare its prognostic utility against postoperative day 1 drain fluid amylase (DFA-1). METHODS Patients who underwent pancreatectomy from January 2019 through March 2020 were identified in the ACS NSQIP pancreatectomy-targeted dataset. POHA grade was assigned using post-operative serum amylase and clinical sequelae. The primary outcome was CR-POPF within 30 days. The association of POHA grade with CR-POPF was assessed using multivariable logistic regression, and c-statistics were used to compare POHA grade versus DFA-1. RESULTS POHA occurred in 520 patients at 98 hospitals, including 261 (50.2%) with grade A, 234 (45.0%) with grade B, and 25 (4.8%) with grade C POHA. CR-POPFs were increased among patients with grade B (66.2%, OR 9.28 [5.84-14.73]) and C (68.0%, OR 10.50 [3.77-29.26]) versus grade A POHA (19.2%). POHA-inclusive models better predicted CR-POPF than those with DFA-1 alone (p < 0.002) and models with both predictors outperformed POHA alone (p = 0.039). CONCLUSION POHA grade represents a measure of post-pancreatectomy outcomes that predicts CR-POPF and outperforms DFA-1 but must be aligned with new international definitions.

Abstract
Background The definition and grading system of post-pancreatectomy acute pancreatitis (PPAP) has recently been proposed by ISGPS. This study aimed to put this definition and classification into practice and investigate the potential risk factors and clinical impacts of PPAP. Methods Demographic and perioperative data of consecutive patients who underwent pancreaticoduodenectomy (PD) from January 2019 to July 2021 were collected and analyzed retrospectively. The diagnostic criteria of PPAP published by ISGPS, consisting of biochemical, radiologic, and clinical parameters, were adopted. The risk factors were analyzed by univariate and multivariate analyses. Results A total of 298 patients were enrolled in this study, and the total incidence of PPAP was 52.4% (150 patients). Stratified by clinical impacts of PPAP, the incidences of grades B and C PPAP were 48.9% and 3.5%, respectively. PPAP after PD was significantly associated with pancreatic fistula and other unfavorable complications. Soft pancreatic texture (OR 3.0) and CRP ≥ 180 mg/L (OR 3.6) were the independent predictors of PPAP, AUC 0.613. Stratified by the grade of PPAP, soft pancreatic texture (OR 2.7) and CRP ≥ 180 mg/L (OR 3.4) were the independent predictors of grade B PPAP, and soft pancreatic texture (OR 19.3), operation duration >360 min (OR 13.8), and the pancreatic anastomosis by using conventional duct to mucosa methods (OR 10.4) were the independent predictors of grade C PPAP. PPAP complicated with pancreatic fistula significantly increased the severe complications and mortality compared to only PPAP occurrence. Conclusion PPAP was not an uncommon complication after PD and was associated with unfavorable clinical outcomes, especially since it was complicated with pancreatic fistula. Soft pancreatic texture and CRP ≥ 180 mg/L were the independent predictors of PPAP. Higher-volume multicenter and prospective studies are strongly needed.

Abstract
INTRODUCTION Postoperative pancreatic fistula (POPF) is one of the major critical complications after pancreatic resection. Recently, postoperative acute pancreatitis (POAP), a new concept for a pancreatic-specific complication following pancreatic resection, has been advocated, and its association with POPF has been reported. The present study examined the clinical features of POAP and identified the associations of POAP with POPF and other postoperative morbidities in pancreatic ductal adenocarcinoma (PDAC) patients undergoing pancreatic resection. METHODS A total of 312 consecutive patients who underwent pancreatic resection for PDAC at our institution from 2013 to 2019 were enrolled in this study. POAP was defined as an elevated serum amylase level above the upper limit normal on postoperative day (POD) 0 or 1, based on Connor's definition. The severity of POPF was assessed by the International Study Group on Pancreatic Surgery definition. RESULTS A total of 184 patients (58.9%) had POAP. POAP occurred in 58.5% of subtotal stomach-preserving pancreatoduodenectomy patients and 60% of distal pancreatectomy combined with splenectomy patients. The presence of POAP was significantly associated with the development of clinically relevant POPF, higher rates of severe morbidity, and a prolonged hospital stay after pancreatic resection. A multivariate analysis showed that the presence of POAP and elevated C-reactive protein levels on POD 3 were independent predictors of clinically relevant POPF after subtotal stomach-preserving pancreatoduodenectomy. CONCLUSIONS POAP is associated with the development of POPF, higher rates of severe morbidity, and a prolonged hospital stay after pancreatic resection and is an independent risk factor for clinically relevant POPF after pancreatoduodenectomy. POAP represents an important indicator for planning treatment strategies to prevent serious complications, including POPF.

Abstract
BACKGROUND The association between postoperative serum hyperamylasaemia (POH) and morbidity has been hypothesized but rarely explored once occurring with or without (POH-exclusive) a combined postoperative pancreatic fistula (POPF). METHODS Analysis of patients who consecutively underwent pancreaticoduodenectomy from 2016 to 2020. POH was defined as serum amylase activity greater than the institutional upper limit of normal (52 U/L), persisting within the first 48 hours postoperatively (postoperative day [POD] 1 and 2). RESULTS Among 852 patients, 15.8% developed POH-exclusive. Compared with patients without POH or POPF (64.3%), they showed a significantly higher postoperative burden (Clavien-Dindo ≥II: 52.6% vs 30.8%) with increased rates of bacteraemia (12.6% vs 6%), pleural effusion (13.3% vs 5.3%), postpancreatectomy haemorrhage (13.3% vs 7.5%), postpancreatectomy acute pancreatitis (PPAP) (10.3% vs 0%), and organ site infections (18.5% vs 10.9%; all P < .05). A total of 13.8% experienced POH with POPF leading to the worse outcome. The combined occurrence of POH with POPF led to a shorter median time to morbidity (3 PODs, 95% confidence interval [CI] 2.2-3.7 vs 6 PODs, 95% CI 4.2-8; P < .001) than patients experiencing POPF-exclusive (5.9%). In all, 46.6% of POH patients developed POPF. Body mass index (BMI) (odds ratio [OR] 1.1), male sex (OR 2.1), increased drain fluid amylase on POD 1 (OR 1.001), and increased C-reactive protein (OR 1.01) were independent risk factors for POPF once POH has occurred. CONCLUSION POH has relevant postoperative clinical implications, independently from POPF occurrence. Developing POH with POPF leads to an earlier onset of higher postoperative burdens. Once POH is diagnosed, risk factors for additional POPF could identify patients who may benefit from additional surveillance, specific drains protocols, and preventive strategies.

Abstract
OBJECTIVE The ISGPS aimed to develop a universally accepted definition for PPAP for standardized reporting and outcome comparison. BACKGROUND PPAP is an increasingly recognized complication after partial pancreatic resections, but its incidence and clinical impact, and even its existence are variable because an internationally accepted consensus definition and grading system are lacking. METHODS The ISGPS developed a consensus definition and grading of PPAP with its members after an evidence review and after a series of discussions and multiple revisions from April 2020 to May 2021. RESULTS We defined PPAP as an acute inflammatory condition of the pancreatic remnant beginning within the first 3 postoperative days after a partial pancreatic resection. The diagnosis requires (1) a sustained postoperative serum hyperamylasemia (POH) greater than the institutional upper limit of normal for at least the first 48 hours postoperatively, (2) associated with clinically relevant features, and (3) radiologic alterations consistent with PPAP. Three different PPAP grades were defined based on the clinical impact: (1) grade postoperative hyperamylasemia, biochemical changes only; (2) grade B, mild or moderate complications; and (3) grade C, severe life-threatening complications. DISCUSSIONS The present definition and grading scale of PPAP, based on biochemical, radiologic, and clinical criteria, are instrumental for a better understanding of PPAP and the spectrum of postoperative complications related to this emerging entity. The current terminology will serve as a reference point for standard assessment and lend itself to developing specific treatments and prevention strategies.

Abstract
Background Recent studies have suggested postoperative acute pancreatitis (POAP) as a serious complication after pancreaticoduodenectomy (PD) and have speculated on its possible role in the pathogenesis of postoperative pancreatic fistula (POPF). This study aimed to assess the impact of POAP on post-PD outcomes and fistula risk score (FRS) performance in predicting POAP. Methods All PDs at Helsinki University Hospital between 2013 and 2020 were analysed. POAP was defined as a plasma amylase activity greater than the normal upper limit on postoperative day (POD) 1 and stratified as clinically relevant (CR)-POAP once C-reactive protein (CRP) reached or exceeded 180 mg/l, and non-CR-POAP once CRP was less than 180 mg/l on POD 2. The Comprehensive Complication Index (CCI) was used to assess total postoperative morbidity. Different FRSs were assessed using receiver operating characteristic curves. Results Of the 508 patients included, POAP occurred in 202 (39.8 per cent) patients, of whom 91 (17.9 per cent) had CR-POAP. The incidence of CR-POPF was 12.6 per cent (64 patients). Patients with non-CR-POAP had a similar morbidity to patients with no POAP (median CCI score 24.2 versus 22.6; P = 0.142), while CCI score was significantly higher (37.2) in patients with CR-POAP (P < 0.001). CR-POAP was associated with increased rates of CR-POPF, delayed gastric emptying, haemorrhage, and bile leak, while non-CR-POAP was associated only with CR-POPF. Ninety-day mortality was 1.6 per cent, 0.9 per cent, and 3.3 per cent in patients with no-POAP, non-CR-POAP, and CR-POAP, respectively. Updated alternative FRS showed the best performance in predicting CR-POAP (area under the curve 0.834). Conclusion CR-POAP was associated with a higher CCI score, suggesting CR-POAP as a distinct entity from non-CR-POAP. FRSs can be used to assess the risk of CR-POAP.

Abstract
BACKGROUND Postoperative pancreatic fistula (POPF) remains a significant complication of pancreatic resection with recent evidence showing a strong association between post-operative pancreatitis and subsequent development of POPF. Incidence and severity of pancreatitis following endoscopic therapy has been effectively reduced with indomethacin prophylaxis, however further agents require evaluation. We present a systematic literature review and meta-analysis of the prophylactic treatment with corticosteroids or n-acetyl cysteine (NAC) of induced pancreatitis in rodent models. METHODS A systematic literature search was conducted using Pubmed, Medline, Embase and Cochrane library to identify eligible randomized control trials (RCT) involving animal models that examined NAC or corticosteroids. The primary outcome was the subsequent effect on serum amylase and IL-6 and the histopathological markers of severity such as pancreatic oedema and necrosis. RESULTS Four RCTs (n = 178) met inclusion criteria examining NAC and eight RCTs (n = 546) examining corticosteroid agents (dexamethasone, hydrocortisone, methylprednisolone). Prophylactic administration of all corticosteroid agents showed a net effect in favour of reducing markers of severity of pancreatitis. NAC showed a significant reduction in severity of amylase and necrosis. CONCLUSION The RCTs examined suggest that prophylactic administration of corticosteroid agents and NAC can reduce the severity of pancreatitis as indicated by histopathologic markers, serum amylase and IL-6 levels.

Abstract
BACKGROUND The clinical relevance of hyperamylasemia after distal pancreatectomy (DP) remains unclear and no internationally accepted definition of postoperative acute pancreatitis (POAP) exists. The aim of this study was to characterize POAP after DP and to assess the role of serum amylase (SA) in POAP. METHODS Outcomes of 641 patients who had undergone DP between 2015 and 2019 were analyzed. Postoperative SA was determined in all patients. POAP was defined based on contrast-enhanced computed tomography (CT) or intraoperative findings during relaparotomy. RESULTS An elevation of SA on postoperative day 1 (hyperamylasemiaPOD1) was found in 398 patients (62.1%). Twelve patients (1.87%) were identified with POAP. Ten patients demonstrated radiologic criteria for POAP and in two patients POAP was diagnosed during relaparotomy. Outcome of POAP patients was worse than that of patients with hyperamylasemiaPOD1 alone and that with normal SAPOD1 without POAP evidence (postoperative pancreatic fistula 50% vs 30.6% vs 18.5%; length of hospital stay 26 days vs 12 vs 11, respectively). The overall 90-day mortality of all 641 patients was 0.6%. CONCLUSION POAP is a serious but rare complication after DP. HyperamylasemiaPOD1 is of prognostic relevance after DP, but it seems not sufficient as a single parameter to diagnose POAP.

Abstract
BACKGROUND Postoperative acute pancreatitis (POAP) emerges as a distinct pancreas-specific complication increasing both the risk and the burden of POPF after pancreatoduodenectomy. Among various risk factors, pancreas stump (PS) hypoperfusion might play a role in POAP occurrence but has never been investigated. The current study aimed at evaluating the feasibility of intraoperative fluorescence angiography (IOFA) of the PS using ICG and its association with POAP. METHODS Consecutive patients who underwent pancreatoduodenectomy for a periampullary tumor with pancreatojejunostomy and PS perfusion assessment using IOFA between January 2020 and November 2020 were prospectively included. Perioperative management and surgical strategy were standardized. IOFA of the pancreas stump was performed before fashioning pancreatojejunostomy. POAP was defined according to the Connor definition and was confirmed upon radiological blind review. Outcomes between patients with normally perfused and hypoperfused PS were compared. POAP was the primary endpoint. RESULTS Among 30 patients, nine patients (30%) developed POAP according to the Connor definition, and six patients (20%) had CT-confirmed POAP. Upon IOFA, six patients (20%) presented PS hypoperfusion; of which one patient underwent extended pancreatectomy further to the left. PS hypoperfusion was statistically associated with the occurrence of POAP (80% vs. 16%; p = 0.011) and CT-confirmed POAP (60% vs. 12%; p = 0.041). Clinically relevant POPF rate was 40% in case of PS hypoperfusion and 4% in case of normal PS perfusion (p = 0.064). CONCLUSIONS PS perfusion assessment using IOFA seems safe and reliable to anticipate POAP. PS IOFA could be considered as a potential tool for perioperative assessment of surgical risk after pancreatoduodenectomy.

Abstract
Background: Prediction of post-pancreaticoduodenectomy (PD) morbidity is difficult, especially in the early postoperative period when CT (Computed Tomography) scans are not available. Elevated serum amylase and lipase in postoperative day 0 or 1 may be used to define postoperative acute pancreatitis (POAP), but the existing literature does not agree on whether POAP is significantly associated with postoperative pancreatic fistula (POPF). Methods: We analyzed the data obtained from a previously published randomized controlled trial. POAP was defined as elevations in serum amylase above 110 U/L on postoperative day 0 or 1. Clinically relevant POAP (CR-POAP) was defined as elevations in C-reactive protein level (CRP) on postoperative day 2 in those with POAP. Postoperative complications including severe complications (Clavien–Dindo ≥ IIIa), POPF, and clinically relevant POPF (CR-POPF) were analyzed. Results: In 246 patients, POAP did not show significant associations with total postoperative complications (odds ratio (OR) 0.697; 95% CI, 0.360–1.313; p = 0.271), severe complications (OR 0.647; 95% CI, 0.258–1.747; p = 0.367), and CR-POPF (OR 0.998; 95% CI, 0.310–3.886; p = 0.998) in multivariable analysis. Conclusions: In patients undergoing PD, POAP was not significantly associated with postoperative complications including POPF. Caution should be taken when using POAP as a predictor of POPF.

Abstract
The use of intraoperative margin revision to achieve margin clearance in patients undergoing pancreatoduodenectomy for pancreatic cancer is controversial. We performed a systematic review and meta-analysis to summarize the evidence of intraoperative margin revisions of the pancreatic neck and its impact on overall survival (OS). Nine studies with 4501 patients were included. Patient cohort was stratified in an R0R0-group (negative margin on frozen and permanent section), R1R0-group (revised positive margin on frozen section which turned negative on permanent section), and R1R1-group (positive margin on frozen and permanent section despite margin revision). OS was higher in the R1R0-group (HR 0.83, 95% CI 0.72-0.96, P = 0.01) compared to the R1R1-group but lower compared to the R0R0-group (HR 1.20; 95% CI 1.05-1.37, P = 0.008), respectively. Subgroup analyses on the use of different margin clearance definitions confirmed an OS benefit in the R1R0-group compared to the R1R1-group (HR 0.81; 95% CI 0.65-0.99, P = 0.04). In conclusion, intraoperative margin clearance of the pancreatic neck margin is associated with improved OS while residual tumor indicates aggressive tumor biology. Consensus definitions on margin terminologies, clearance, and surgical techniques are required.

Abstract
BACKGROUND Morbid obesity is a risk factor for pancreatic ductal adenocarcinoma (PDAC). However, the impact of obesity on postoperative outcomes and overall survival in patients with PDAC remains a controversial topic. METHODS Patients who underwent pancreatic surgery for PDAC between 1997 and 2018 were included in this study. Matched pairs (1:1) were generated according to age, gender and American Society of Anesthesiologists status. Obesity was defined according to the WHO definition as BMI ≥ 30 kg/m2. The primary endpoint was the difference in overall survival between patients with and without obesity. RESULTS Out of 553 patients, a total of 76 fully matched pairs were generated. Obese patients had a mean BMI-level of 33 compared to 25 kg/m2 in patients without obesity (p = 0.001). The frequency of arterial hypertension (p = 0.002), intraoperative blood loss (p = 0.039), and perineural invasion (p = 0.033) were also higher in obese patients. Clinically relevant postoperative complications (p = 0.163) and overall survival rates (p = 0.885) were comparable in both study groups. Grade II and III obesity resulted in an impaired overall survival, although this was not statistically significant. Subgroup survival analyses revealed no significant differences for completion of adjuvant chemotherapy and curative-intent surgery. CONCLUSIONS Obesity did not affect overall survival and postoperative complications in these patients with PDAC. Therefore, pancreatic surgery should not be withheld from obese patients.

Abstract
BACKGROUND Postoperative acute pancreatitis has recently been reported as a specific complication after pancreatoduodenectomy. The aim of this study was to characterize postoperative acute pancreatitis after distal pancreatectomy. METHODS We analyzed the outcomes retrospectively of 368 patients who underwent distal pancreatectomies during the period January 2016 to December 2019. Postoperative acute pancreatitis was defined as an increase of serum amylase activity greater than our laboratory normal upper limit on postoperative days 0 to 2. We assessed the incidence of postoperative acute pancreatitis after distal pancreatectomy and examined possible predictors of postoperative acute pancreatitis and relationships of postoperative acute pancreatitis with postoperative pancreatic fistula. RESULTS The rates of postoperative acute pancreatitis and postoperative pancreatic fistula after distal pancreatectomy were 67.9% and 28.8%, respectively. Patients who developed postoperative acute pancreatitis experienced an increased rate of severe morbidity (18.4 vs 9.3%; P = .030). Neoadjuvant therapy (odds ratio 0.28, 0.09-0.85; P = .025), age ≥ 65 y (odds ratio 0.34, 0.13-0.85; P = .020), duct size (odds ratio 0.02, 0.002-0.47; P = .013), pancreatic thickness (odds ratio 3.4, 1.29-8.9; P = .013), resection at the body-tail level (odds ratio 4.3, 1.15-23.19; P = .041), and neuroendocrine histology (odds ratio 1.14, 1.06-3.90; P = .013) were independent predictors of postoperative acute pancreatitis. Furthermore, postoperative acute pancreatitis was an independent predictor of postoperative pancreatic fistula (odds ratio 5.8, 2.27-15.20; P < .001). Postoperative pancreatic fistula occurred in 37% of patients who developed postoperative acute pancreatitis. Patients developing postoperative acute pancreatitis alone demonstrated a statistically significantly increased rate of biochemical leakage and bacterial contamination in the peripancreatic drainage fluid. CONCLUSION Postoperative acute pancreatitis is a frequent event after distal pancreatectomy and, despite its close association with postoperative pancreatic fistula, evidently represents a separate phenomenon. A universally accepted definition of postoperative acute pancreatitis that applies to all types of pancreatic resections is needed, because it may identify patients at greater risk for additional morbidity immediately after pancreatic resections.

Hyperamylasemia and acute pancreatitis after pancreatoduodenectomy: Two different entities. Surgery 2020; 169:369-376. [PMID: 32981689 DOI: 10.1016/j.surg.2020.07.050] [Citation(s) in RCA: 30] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2020] [Revised: 07/16/2020] [Accepted: 07/24/2020] [Indexed: 12/12/2022]
Abstract
BACKGROUND Serum amylase activity greater than the institutional upper limit of normal (hyperamylasemia) on postoperative day 0-2 has been suggested as a criterion to define postoperative acute pancreatitis after pancreatoduodenectomy, but robust evidence supporting this definition is lacking. BACKGROUND To assess the clinical impact of hyperamylasemia after pancreatoduodenectomy and to define postoperative acute pancreatitis. METHODS Data of 1,235 consecutive patients who had undergone pancreatoduodenectomy between January 2010 and December 2014 were extracted from a prospective database and analyzed. Postoperative acute pancreatitis was defined based on the computed tomography severity index. Logistic regression modeling was used to calculate the postoperative acute pancreatitis rate of the entire study population. RESULTS Hyperamylasemia on postoperative day 1 was found in 52% of patients after pancreatoduodenectomy. Patients with hyperamylasemia on postoperative day 1 had statistically significantly greater morbidity and mortality than patients with a normal serum amylase activity on postoperative day 1 with the rates of postoperative pancreatic fistula of 14.5% vs 2.1%, and 90-day mortality of 6.6% vs 2.2%, respectively. Of the 364 patients who underwent postoperative computed tomography, 103 (28%) had radiologic signs of acute pancreatitis, thus defining them as having postoperative acute pancreatitis by our definition. Logistic regression modeling showed a 14.7% rate of postoperative acute pancreatitis for the entire patient cohort and 29.2% for patients with hyperamylasemia on postoperative day 1. Outcomes of patients with postoperative acute pancreatitis defined based on the computed tomography severity index showed a rate of postoperative pancreatic fistula of 32.4% and a 90-day mortality rate of 11.8%, which were worse than those of patients with hyperamylasemia on postoperative day 1 alone. CONCLUSION Hyperamylasemia on postoperative day 1 is a frequent finding after pancreatoduodenectomy, but hyperamylasemia on postoperative day 1 alone is not synonymous with postoperative acute pancreatitis because only 29.2% of such patients have acute pancreatitis based on computed tomography findings. Postoperative acute pancreatitis is a dangerous complication after pancreatoduodenectomy, but its prevalence, according to the gold standard of CT, is not as high as reported previously. Our data suggest that hyperamylasemia on postoperative day 1 and postoperative acute pancreatitis are 2 different entities.

Clinical course and pancreas parenchyma sparing surgical treatment of severe pancreatic trauma. Injury 2020; 51:1979-1986. [PMID: 32336477 DOI: 10.1016/j.injury.2020.03.045] [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: 01/22/2020] [Revised: 03/11/2020] [Accepted: 03/27/2020] [Indexed: 02/02/2023]
Abstract
INTRODUCTION Pancreatic trauma (PT) involving the main pancreatic duct is rare, but represents a challenging clinical problem with relevant morbidity and mortality. It is generally classified according to the American Association for the Surgery of Trauma (AAST) and often presents as concomitant injury in blunt or penetrating abdominal trauma. Diagnosis may be delayed because of a lack of clinical or radiological manifestation. Treatment options for main pancreatic duct injuries comprise highly complex surgical procedures. PATIENTS AND METHODS We retrospectively analyzed clinical data from 12 patients who underwent surgery in two tertiary centers in Germany during 2003-2016 for grade III-V PT with affection of the main pancreatic duct, according to the AAST classification. RESULTS The median age was 23 (range: 7-44) years. In nine patients blunt abdominal trauma was the reason for PT, whereas penetrating trauma only occurred in three patients. MRI outperformed classical trauma CT imaging with regard to detection of duct involvement. Complex procedures as i.e. an emergency pancreatic head resection, distal pancreatectomy or parenchyma sparing pancreatogastrostomy were performed. Compared to elective pancreatic surgery the complication rate in the emergency setting was higher. Yet, parenchyma-sparing procedures demonstrated safety. CONCLUSIONS Often extension of diagnostics including MRI and/or ERP at an early stage is necessary to guide clinical decision-making. If, due to main duct injuries, surgical therapy for PT is required, we suggest consideration of an organ preservative pancreatogastrostomy in grade III/IV trauma of the pancreatic body or tail.

Post-operative morbidity following pancreatic duct occlusion without anastomosis after pancreaticoduodenectomy: a systematic review and meta-analysis. HPB (Oxford) 2020; 22:1092-1101. [PMID: 32471694 DOI: 10.1016/j.hpb.2020.04.014] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/10/2020] [Revised: 04/21/2020] [Accepted: 04/23/2020] [Indexed: 12/12/2022]
Abstract
BACKGROUND Pancreatic duct occlusion (PDO) without anastomosis is a technique proposed to mitigate the clinical consequences of postoperative pancreatic fistulas (POPF) after pancreaticoduodenectomy. The aim of this study was to appraise the morbidity following PDO through a systematic review and meta-analysis. METHODS A systematic search of MEDLINE, Embase, and Web Of Science identified studies reporting outcomes of PDO following pancreaticoduodenectomy. Pooled prevalence rates of postoperative complications and mortality were computed using random-effect modeling. Meta-regression analyses were performed to examine the impact of moderators on the overall estimates. RESULTS Sixteen studies involving 1000 patients were included. Pooled postoperative mortality was 2.7%. A POPF was reported in 29.7% of the patients. Clinically relevant POPFs occurred in 13.5% of the patients, while intra-abdominal abscess and haemorrhages occurred in 6.7% and 5.5% of the patients, respectively. Re-operation was necessary in 7.6% of the patients. Postoperatively new onset diabetes occurred in 15.8% of patients, more frequently after the use of chemical substances for PDO (p = 0.003). CONCLUSIONS PDO is associated with significant morbidity including new onset of post-operative diabetes. The risk of new onset post-operative diabetes is associated with the use of chemical substance for PDO. Further evidence is needed to evaluate the potential benefits of PDO in patients at high risk of POPF.

Postoperative hyperamylasemia (POH) and acute pancreatitis after pancreatoduodenectomy (POAP): State of the art and systematic review. Surgery 2020; 169:377-387. [PMID: 32641279 DOI: 10.1016/j.surg.2020.04.062] [Citation(s) in RCA: 25] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2020] [Revised: 04/20/2020] [Accepted: 04/25/2020] [Indexed: 12/13/2022]
Abstract
BACKGROUND Postoperative hyperamylasemia is a frequent finding after pancreatoduodenectomy, but its incidence and clinical implications have not yet been analyzed systematically. The aim of this review is to reappraise the concept of postoperative hyperamylasemia with postoperative acute pancreatitis, including its definition, interpretation, and correlation. METHODS Online databases were used to search all available relevant literature published through June 2019. The following search terms were used: "pancreaticoduodenectomy," "amylase," and "pancreatitis." Surgical series reporting data on postoperative hyperamylasemia or postoperative acute pancreatitis were selected and screened. RESULTS Among 379 screened studies, 39 papers were included and comprised data from a total of 9,220 patients. Postoperative hyperamylasemia was rarely defined in most of these series, and serum amylase values were measured at different cutoff levels and reported on different postoperative days. The actual levels of serum amylase activity and the representative cutoff levels required to reach a diagnosis of postoperative acute pancreatitis were markedly greater on the first postoperative days and tended to decrease over time. Most studies analyzing postoperative hyperamylasemia focused on its correlation with postoperative pancreatic fistula and other postoperative morbidities. The incidence of postoperative acute pancreatitis varied markedly between studies, with its definition completely lacking in 40% of the analyzed papers. A soft pancreatic parenchyma, a small pancreatic duct, and pathology differing from cancer or chronic pancreatitis were all predisposing factors to the development of postoperative hyperamylasemia. CONCLUSION Postoperative hyperamylasemia has been proposed as the biochemical expression of pancreatic parenchymal injury related to localized ischemia and inflammation of the pancreatic stump. Such phenomena, analogous to those associated with acute pancreatitis, could perhaps be renamed as postoperative acute pancreatitis from a clinical standpoint. Patients with postoperative acute pancreatitis experienced an increased rate of all postoperative complications, particularly postoperative pancreatic fistula. Taken together, the discrepancies among previous studies of postoperative hyperamylasemia and postoperative acute pancreatitis outlined in the present review may provide a basis for stronger evidence necessary for the development of universally accepted definitions for postoperative hyperamylasemia and postoperative acute pancreatitis.

Abstract
BACKGROUND Cholangitis is a serious biliary complication following biliary-enteric anastomosis (BEA). However, the rate of cholangitis in the postoperative period and its associated risk factors are inconclusive. The objective of this systematic review and meta-analysis was to assess the onset and risk factors of cholangitis after biliary-enteric reconstruction in literature. METHODS MEDLINE, EMBASE, and Cochrane databases were searched systematically to identify studies reporting about cholangitis following biliary-enteric anastomosis. Meta-analyses were performed for risk factors using random effects model with odds ratio (OR) and 95% confidence interval (95 %CI) as effect measures. Study quality was assessed by the MINORS (methodological index for non-randomized studies) criteria. RESULTS 28 studies involving 6904 patients were included in the study. The pooled rate for postoperative cholangitis (POC) was 10% (95 %CI: 8 %-13%) with studies reporting about an early- and late-onset of cholangitis. Male sex (OR 2.08; 95 %CI: 1.33-3.24; P = 0.001), postoperative hepatolithiasis (OR 137.19; 95 %CI: 29.00-648.97; P < 0.001) and postoperative anastomotic stricture (OR 178.29; 95 %CI: 68.64-463.11; P < 0.001) were associated with a higher risk of a late-onset of POC with a pooled rate of 8% (95 %CI: 6 %-11%) after a median time interval of 12 months. The quality of the included studies was low to moderate. CONCLUSION Cholangitis is a frequent complication after BEA. Consensus definition and prospective trials are required to assess optimal therapeutic strategies. We proposed a standardized definition and grading of POC to enable comparisons between future studies.

Pancreatology 2020; 20:211-216. [PMID: 31831390 DOI: 10.1016/j.pan.2019.11.014] [Citation(s) in RCA: 27] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/15/2019] [Revised: 11/10/2019] [Accepted: 11/23/2019] [Indexed: 12/11/2022]
Abstract
BACKGROUND Postoperative acute pancreatitis (POAP) after pancreaticoduodenectomy (PD) has been recently recognized as an independent complication that is associated with undesirable postoperative outcomes and often precedes other complications, yet predictive factors attributable to POAP after PD remain elusive. METHODS The data from 1465 consecutive patients who underwent laparotomy or minimally invasive robotic PD from March 2010 to December 2018 were retrospectively reviewed. POAP was defined as an elevation of the serum amylase levels above the institution's normal upper limit (100 U/L) on postoperative day (POD) 1. Univariate and multivariate analyses were performed to investigate the predictive factors for POAP after PD and the association between POAP and clinically relevant postoperative pancreatic fistulas (CR-POPFs). RESULTS Among the 1465 patients, 411 (28%) underwent minimally invasive robotic surgeries, and the overall POAP and CR-POPFs rates were 770 (53%) and 277 (19%), respectively. The female sex (OR 1.76), a normal bilirubin level (OR 1.55), the robotic surgery (OR 1.36), a main pancreatic duct (MPD) ≤3 mm (OR 5.69) and a high-risk nonadenocarcinoma pathology (cystic disease: OR 4.33; pNETs: OR 4.34; others: OR 2.74) were considered independent risk factors for POAP. A nondilated MPD was a predominant predictor for POAP, with 72.2% sensitivity and 71.8% specificity. POAP was also an independent predictive factor for CR-POPFs (OR 3.48). CONCLUSION A nondilated MPD, a high-risk pathology, the female sex, a normal bilirubin level and the robotic surgery were independent predictive factors for POAP after PD. Prevention and early treatment strategy changes can be made based on these preoperative predictive factors.
