Review
Pancreatic cancer is the seventh leading cause of cancer deaths worldwide, accounting for 4.7% of all cancer deaths, and is expected to climb significantly over the next decade. The purpose of this systematic review and guidance document was to synthesize the evidence surrounding the role of adjuvant treatment (chemotherapy and chemoradiation therapy [CRT], and stereotactic body radiation therapy [SBRT]) in resected pancreatic ductal adenocarcinoma (PDAC). Systematic literature searches of MEDLINE, EMBASE, and 11 guideline databases were conducted. Both direct and indirect comparisons indicate adjuvant chemotherapy offers a survival advantage over surgery alone. The optimal regimens recommended are mFOLFIRINOX with alternative options of gemcitabine plus capecitabine, gemcitabine alone, or S-1 (which is not available in North America). Trials comparing a CRT strategy to modern chemotherapy regimens are lacking. However, current evidence demonstrates that the addition of CRT to chemotherapy does not result in a survival advantage over chemotherapy alone and is therefore not recommended. Trials evaluating SBRT in PDAC are also lacking. SBRT should only be used within a clinical trial or multi-institutional registry.

INTRODUCTION
The prevalence of non-alcoholic fatty pancreas disease (NAFPD) is estimated as 2-46% among patients without known pancreatic diseases. An association between NAFPD and non-alcoholic fatty liver disease (NAFLD) has been proposed, as well as an association between NAFPD and pancreatic exocrine insufficiency (PEI).
PATIENTS AND METHODS
Patients with histologically confirmed NAFLD were included in the study. The control group consisted of individuals included in a surveillance screening program. Magnetic resonance imaging (MRI) of the pancreas was performed in all patients and fat measurement was made using 2-point Dixon imaging. Fecal elastase-1 (FE-1) was performed to evaluate pancreatic exocrine function. Additionally, a C-mixed triglyceride breath test (13 C-MTG-BT) was performed in patients with FE-1 < 200 μg/g.
RESULTS
Imaging signs of NAFPD were present in 17 (71%) patients; 11 (85%) from the NAFLD group and 6 (55%) from the control group. FE-1 < 200 μg/g was found in six (25%) patients (four in the NAFLD group and two in the control group); however, none of them had clinical symptoms of PEI. Therefore, in five out of six patients with low FE-1, a C-MTG-BT was performed, showing normal results (>20.9%) in all tested patients. Furthermore, the serum nutritional panel was normal in all patients with low FE-1. A systematic review identified five studies relevant to the topic.
CONCLUSION
NAFPD was found in 85% of patients with NAFLD and in 55% of control patients. We did not diagnose PEI in either group. A literature review showed PEI in 9-56% of patients with NAFPD.

Meta-Analysis Review
OBJECTIVE
The meta-analysis was conducted to test the link between pancreatic cancer (PC) risk and dietary inflammatory index (DII®) score.
DESIGN
Systematic review and meta-analysis.
SETTING
We searched PubMed, Embase, Web of Science and the Cochrane Library up to 22 November 2020 to identify the relevant studies. Studies that reported the risk estimates and the corresponding 95 % CI for the DII category and PC risk were included. The effect sizes were pooled using the random-effects model. Dose-response analysis was conducted where possible.
PARTICIPANTS
Two prospective cohort studies of 634 705 participants (3152 incident cases), and four case-control studies of 2737 cases and 4861 controls.
RESULTS
Overall, the pooled risk ratio (RR) indicated that individuals in the highest category compared with the lowest category had an increased PC risk (RR = 1·45; 95 % CI 1·11, 1·90; P = 0·006). Meanwhile, significant heterogeneity was also revealed. The dose-response meta-analysis indicated that a 1-unit increase in the DII score was associated with the PC risk (RR = 1·08; 95 % CI 1·002, 1·166; P = 0·045; I2 = 94·1 %, P < 0·001). Nonlinear result showed an increased risk of moving from fewer to more inflammatory borders with increasing DII score (Pnonlinearity = 0·003; I2 = 76·5 %, P < 0·001). Subgroup analyses found that significant positive association between PC risk and DII score appeared to be in case-control studies (RR = 1·70; 95 % CI 1·16, 2·50; P = 0·007) and studies with ≤ 31 DII components (RR = 1·76; 95 % CI 1·14, 2·72; P = 0·011).
CONCLUSION
These findings suggested dietary habits with high inflammatory features (high DII score) might increase PC risk.

Meta-Analysis
BACKGROUND
Diagnosing pancreatic lesions, including chronic pancreatitis, autoimmune pancreatitis, and pancreatic cancer, poses a challenge and, as a result, is time-consuming. To tackle this issue, artificial intelligence (AI) has been increasingly utilized over the years. AI can analyze large data sets with heightened accuracy, reduce interobserver variability, and can standardize the interpretation of radiologic and histopathologic lesions. Therefore, this study aims to review the use of AI in the detection and differentiation of pancreatic space-occupying lesions and to compare AI-assisted endoscopic ultrasound (EUS) with conventional EUS in terms of their detection capabilities.
METHODS
Literature searches were conducted through PubMed/Medline, SCOPUS, and Embase to identify studies eligible for inclusion. Original articles, including observational studies, randomized control trials, systematic reviews, meta-analyses, and case series specifically focused on AI-assisted EUS in adults, were included. Data were extracted and pooled, and a meta-analysis was conducted using Meta-xl. For results exhibiting significant heterogeneity, a random-effects model was employed; otherwise, a fixed-effects model was utilized.
RESULTS
A total of 21 studies were included in the review with four studies pooled for a meta-analysis. A pooled accuracy of 93.6% (CI 90.4-96.8%) was found using the random-effects model on four studies that showed significant heterogeneity ( P <0.05) in the Cochrane's Q test. Further, a pooled sensitivity of 93.9% (CI 92.4-95.3%) was found using a fixed-effects model on seven studies that showed no significant heterogeneity in the Cochrane's Q test. When it came to pooled specificity, a fixed-effects model was utilized in six studies that showed no significant heterogeneity in the Cochrane's Q test and determined as 93.1% (CI 90.7-95.4%). The pooled positive predictive value which was done using the random-effects model on six studies that showed significant heterogeneity was 91.6% (CI 87.3-95.8%). The pooled negative predictive value which was done using the random-effects model on six studies that showed significant heterogeneity was 93.6% (CI 90.4-96.8%).
CONCLUSION
AI-assisted EUS shows a high degree of accuracy in the detection and differentiation of pancreatic space-occupying lesions over conventional EUS. Its application may promote prompt and accurate diagnosis of pancreatic pathologies.

Meta-Analysis Review
BACKGROUND
Central pancreatectomy is usually performed to excise lesions of the neck or proximal body of the pancreas. In the last decade, thanks to the advent of novel technologies, surgeons have started to perform this procedure robotically. This review aims to appraise the results and outcomes of robotic central pancreatectomies (RCP) through a systematic review and meta-analysis.
METHODS
A systematic search of MEDLINE, Embase, and Web Of Science identified studies reporting outcomes of RCP. Pooled prevalence rates of postoperative complications and mortality were computed using random-effect modelling.
RESULTS
Thirteen series involving 265 patients were included. In all cases but one, RCP was performed to excise benign or low-grade tumours. Clinically relevant post-operative pancreatic fistula (POPF) occurred in 42.3% of patients. While overall complications were reported in 57.5% of patients, only 9.4% had a Clavien-Dindo score ≥ III. Re-operation was necessary in 0.7% of the patients. New-onset diabetes occurred postoperatively in 0.3% of patients and negligible mortality and open conversion rates were observed.
CONCLUSION
RCP is safe and associated with low perioperative mortality and well preserved postoperative pancreatic function, although burdened by high overall morbidity and POPF rates.

Review
INTRODUCTION
The increase in the incidence of pancreatic and biliary cancers has attracted the search for methods of early detection of diseases and biomarkers. The authors propose to analyze new findings on the association between microbiota and Pancreatic Ductal Adenocarcinoma (PDAC) or Cholangiocarcinoma (CCA).
METHODS
This systematic review was carried out according to the items of Preferred Reports for Systematic Reviews and Protocol Meta-Analysis (PRISMA-P). This study was registered by the Prospective Register of Systematic Reviews (PROSPERO), identification code CRD42020192748 before the review was carried out. Articles were selected from the PUBMED, EMBASE, and Cochrane databases.
RESULTS
Most studies (86.67%) used 16s rRNA as a sequencing method. The main comorbidities found were diabetes mellitus, systemic arterial hypertension, and dyslipidemia. Many studies were limited by the small number of participants, but the biases were mostly low. There was very little concordance about the composition of the microbiome of different sites, for both case and control groups when compared to other studies' results. Bile sample analysis was the one with a greater agreement between studies, as three out of four studies found Escherichia in cases of CCA.
CONCLUSION
There was great disagreement in the characterization of both the microbiota of cases and control groups. Studies are still scarce, making it difficult to adequately assess the data in this regard. It was not possible to specify any marker or to associate any genus of microbiota bacteria with PDAC or CCA.

Meta-Analysis Review
BACKGROUND
The number of pancreatic resections due to cancers is increasing. While concomitant venous resections are routinely performed in specialized centers, arterial resections are still controversial. Nevertheless they are performed in patients presenting with locally advanced tumors. Our aim was to summarize currently available literature comparing peri-operative and long-term outcomes of arterial and non-arterial pancreatic resections.
METHODS
We included studies comparing pancreatic operations with and without concomitant arterial resection. Inclusion criteria were morbidity or mortality. Studies additionally reporting venous resections with no possibility of excluding this data during the extraction were discarded.
RESULTS
The initial search yielded 1651 records. Finally, 19 studies were included in the analysis involving 2710 patients. Arterial resection was associated with a greater risk of death(RR: 4.09; p < 0.001) and complications (RR: 1.4; p = 0.01). There were no differences in the rate of pancreatic fistula, biliary fistula rate, cardiopulmonary complications, length of hospital stay and non-R0 rate. Oncologically, patients after arterial resection were at higher risk of worse 3-year survival.
CONCLUSION
Arterial resection in pancreatic cancer is associated with an increased risk of mortality and complications in comparison to standard non-arterial resections. Nevertheless, arterial resection may become a viable treatment for selected patients in high volume centers.

Meta-Analysis Review
Background: Celiac disease (CD) is an autoimmune enteropathy affecting approximately 1% of the population and is associated with an increased risk of enteropathy-associated T-cell lymphoma and small bowel adenocarcinoma, whereas the association between CD and other malignancies is unclear. Since pancreatic cancer (PC) remains one of the most lethal neoplasms and its incidence is increasing despite numerous ongoing research on diagnostic biomarkers and novel therapies, we aimed to investigate whether CD has an impact on the risk of PC. Material and Methods: We performed a systematic review of the literature published from January 2000 to March 2022 in two databases: Web of Science and Scopus and a meta-analysis of eligible studies. Results: Our search identified eight publications included in the systematic review. A total of five studies involving 47,941 patients, including 6399 CD patients with malignancies and 1231 PC cases were included in the meta-analysis and 221 cases of PC in CD patients with other cancers were recognized. The pooled OR for PC was 1.46 (95% CI 1.26−1.7) with significant heterogeneity (89.1%; p < 0.05), suggesting that CD patients with malignancies were at higher risk for PC. Conclusions: The association between CD and PC is uncertain. However, the results of the current meta-analysis may indicate an increased risk of PC in the group of patients with CD and other cancers. Further multicenter studies are warranted.

Review
Inflammatory bowel disease (IBD) is a chronic condition and mainly affects the intestines, however, the involvement of the other organs of the gastrointestinal tract (upper part, pancreas, and liver) have been observed. The coexistence of IBD with pancreatic pathology is rare, however, it has been diagnosed more frequently during recent years in the pediatric population. This article reviews the current literature on the most common pancreatic diseases associated with IBD in the pediatric population and their relationship with IBD activity and treatment. We performed a systematic review of data from published studies on pancreatic disorders, also reported as extraintestinal manifestations (EIMs), among children with IBD. We searched PubMed and Web of Science to identify eligible studies published prior to 25 April 2020. Forty-four papers were chosen for analysis after a detailed inspection, which aimed to keep only the research studies (case control studies and cohort studies) or case reports on children and only those which were written in English. The manifestations of IBD-associated pancreatic disorders range from asymptomatic increase in pancreatic enzymes activity to severe disease such as acute pancreatitis. Acute pancreatitis (AP) induced by drugs, mainly thiopurine, seems to be the most- often-reported pancreatic disease associated with IBD in children. AP associated with other than drug etiologies, and chronic pancreatitis (CP), are rarely observed in the course of pediatric IBD. The pancreatic involvement can be strictly related to the activity of IBD and can also precede the diagnosis of IBD in some pediatric patients. The course of AP is mild in most cases and may occasionally lead to the development of CP, mainly in cases with a genetic predisposition. The involvement of the pancreas in the course of IBD may be considered as an EIM or a separate co-morbid disease, but it can also be a side effect of IBD therapy, therefore a differential diagnosis should always be performed. As the number of IBD incidences with concomitant pancreatic diseases is constantly increasing in the pediatric population, it is important to include pancreatic enzymes level measurement in the workup of IBD.

BACKGROUND
Shwachman-Diamond syndrome (SDS) is an autosomal recessive disease which results in inherited bone marrow failure (IBMF) and is characterized by exocrine pancreatic dysfunction and diverse clinical phenotypes. In the present study, we reviewed the internationally published reports on SDS patients, in order to summarize the clinical features, epidemiology, and treatment of SDS.
METHODS
We searched the WangFang and China National Knowledge Infrastructure databases with the keywords "Shwachman-Diamond syndrome," "SDS," "SBDS gene" and "inherited bone marrow failure" for relevant articles published from January 2002 to October 2022. In addition, studies published from January 2002 to October 2022 were searched from the Web of Science, PubMed, and MEDLINE databases, using "Shwachman-diamond syndrome" as the keyword. Finally, one child with SDS treated in Tongji Hospital was also included.
RESULTS
The clinical features of 156 patients with SDS were summarized. The three major clinical features of SDS were found to be peripheral blood cytopenia (96.8%), exocrine pancreatic dysfunction (83.3%), and failure to thrive (83.3%). The detection rate of SDS mutations was 94.6% (125/132). Mutations in SBDS, DNAJC21, SRP54, ELF6, and ELF1 have been reported. The male-to-female ratio was approximately 1.3/1. The median age of onset was 0.16 years, but the diagnostic age lagged by a median age of 1.3 years.
CONCLUSIONS
Pancreatic exocrine insufficiency and growth failure were common initial symptoms. SDS onset occurred early in childhood, and individual differences were obvious. Comprehensive collection and analysis of case-related data can help clinicians understand the clinical characteristics of SDS, which may improve early diagnosis and promote effective clinical intervention.
