Meta-Analysis
The effect of gallstones and cholecystectomy on the development of pancreatic cancer has recently prompted many population-based studies. However, the results are controversial. We conducted an updated systematic review and meta-analysis to explore the causality among gallstones, cholecystectomy and pancreatic cancer. Cohort studies published in the PubMed, Web of Science, Embase, and Cochrane Library databases up to May 2023 were retrieved. Pooled relative risks (RRs) and 95% confidence intervals (CIs) were analyzed using a random-effects model. We screened 1391 articles and included 16 studies. Gallstones were not associated with an increased risk of pancreatic cancer ( P = 0.082), with only the Asian population ( P = 0.011) showing an increased risk in the subgroup analysis. A markedly higher risk of pancreatic cancer was observed among patients with cholecystectomy (RR = 1.23; 95% CI, 1.07-1.41; P = 0.004; I 2 = 74.4%). The association remained significant in the Asian population ( P = 0.004), in the subgroup analyses stratified by sex, lag period, and time interval since cholecystectomy, and when the models were adjusted for diabetes, smoking, and BMI. Interestingly, cholecystectomy due to gallstones (RR = 1.30; 95% CI, 1.14-1.48; P < 0.001; I 2 = 30.8%), rather than for unspecified reasons ( P = 0.116), markedly increased the risk of pancreatic cancer. In conclusion, cholecystectomy due to gallstones, rather than gallstone formation, conferred an increased risk for pancreatic cancer. There was a higher risk for the Asian population for both gallstones and cholecystectomy.

Review
BACKGROUND
Pancreatic trauma is an uncommon injury that occurs usually in a young population and is frequently overlooked and not readily appreciated on initial examination. Nowadays, the diagnosis and management of pancreatic trauma are still controversial, and there is no gold standard for the treatment. The aim of this study is to describe our experience in the management of blunt pancreatic trauma with a laparoscopic approach and review the literature on laparoscopic management of pancreatic trauma.
METHODS
A systematic literature review was performed, and 40 cases were reported and analysed; 10 cases were excluded because the complete data were not retrievable. We also reported our experience with the case of an 18-year-old male diagnosed with a deep laceration of the pancreas between body and tail, involving the main pancreatic duct, and with a concomitant hematoma. The patient underwent exploratory laparoscopy with abdominal toilet, necrosectomy, and suture of main pancreatic duct; the total blood loss was less than 200 ml, and the total operative time was 180 minutes. The patient recovered uneventfully and was discharged on the 6th postoperative day.
RESULTS
30 patients with pancreatic trauma, 10 adults and 20 pediatrics (mean age 28.2 years and 10.5 years), underwent a total laparoscopic approach: 2 distal pancreatic-splenectomy, 22 spleen-preserving distal pancreatectomy, and 6 laparoscopic drainage. The mean operative time for the adult and pediatric populations was 160.6 and 214.5 minutes, the mean estimated blood loss was 400 ml and 75 ml, and the mean hospital stay was 14.9 and 9 days, respectively.
CONCLUSION
Laparoscopic management for pancreatic trauma can be considered feasible and safe when performed by an experienced laparoscopic pancreatic team, and in such a setting, it can be considered a viable alternative to open surgery, offering the well-known benefits of minimally invasive surgery.

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.

Hilar cholangiocarcinoma (HCCA) is widely considered to have a poor prognosis. In particular, combined caudate lobe resection (CLR) as a strategy for radical resection in HCCA is important for improving the R0 resection rate. However, the criteria for R0 resection, necessity of CLR, optimal extent of hepatic resection, and surgical approach are still controversial. This review aimed to summarize the findings and discuss the controversies surrounding CLR. Numerous clinical studies have shown that combined CLR treatment for HCCA improves the R0 resection rate and postoperative survival time. Whether surgery for Bismuth type I or II is combined with CLR depends on the pathological type. Considering the anatomical factors, total rather than partial CLR is recommended to achieve a higher R0 resection rate. In the resection of HCCA, a proximal ductal margin greater than or equal to 10 mm should be achieved to obtain a survival benefit. Although there is no obvious boundary between the right side (especially the paracaval portion) and the right posterior lobe of the liver, Peng's resection line can serve as a reference marker for right-sided resection. Laparoscopic resection of the caudate lobe may be safer, more convenient, accurate, and minimally invasive than open surgery, but it needs to be completed by experienced laparoscopic doctors.

Meta-Analysis Comparative Study Review
Poly (ADP-ribose) Polymerase Inhibitors Have Comparable Efficacy with Platinum Chemotherapy in Patients with BRCA-positive Metastatic Castration-resistant Prostate Cancer. A Systematic Review and Meta-analysis.
CONTEXT
Testing for mutations in Breast Cancer Gene 1/2 (BRCA) has emerged as a novel decision-making tool for clinicians. Patients with metastatic castration-resistant prostate cancer (mCRPC) harboring pathogenic BRCA mutations can benefit from poly (ADP-ribose) polymerase inhibitor (PARPi) and platinum treatments, whereas the impact of the mutation on sensitivity to cabazitaxel and prostate-specific membrane antigen (PSMA)-ligand therapy is currently unknown.
OBJECTIVE
To assess the efficacy of PARPi, platinum, cabazitaxel, and PSMA-ligand therapies in BRCA-positive mCRPC.
EVIDENCE ACQUISITION
Databases were queried in February 2022. We performed data synthesis by using both proportional and individual patient data. For prostate-specific antigen (PSA) response rate (≥50% decrease from baseline [PSA50]) evaluation, we pooled event rates with 95% confidence intervals (CIs). Progression-free (PFS) and overall (OS) survival analyses with individual patient data were performed with the mixed-effect Cox proportional hazard model and single-arm random-effect analysis, providing pooled medians.
EVIDENCE SYNTHESIS
We included 23 eligible studies with 901 BRCA-positive mCRPC patients. PSA50 response rates for PARPi and platinum were 69% (CI: 53-82%), and 74% (CI: 49-90%), respectively. Analyses of OS data showed no difference between PARPi and platinum treatments (hazard ratio: 0.86; CI: 0.49-1.52; p = 0.6). The single-arm OS and PFS analyses revealed similarities among different PARPis; pooled PFS and OS medians were 9.7 mo (CI: 8.1-12.5) and 17.4 mo (CI: 12.7-20.1), respectively.
CONCLUSIONS
Our data revealed that different PARPis were similarly effective in terms of PFS and OS. Moreover, we found that PARPi and platinum therapy were comparable in terms of PSA50 response rate and OS, highlighting that platinum is a valid treatment option for BRCA-positive mCRPC patients. However, prospective interventional studies comparing these agents are essential to provide a higher level of evidence.
PATIENT SUMMARY
In this report, we found that different poly (ADP-ribose) polymerase inhibitors had similar efficacy, and platinum was a valid treatment option in BRCA-positive metastatic castration-resistant prostate cancer patients.

Review
OBJECTIVES
This systematic review aimed to analyze the effects of different exercise protocols on physical fitness (cardiorespiratory fitness, muscle strength, and body composition), quality of life, cancer-related fatigue, and sleep quality in patients with different types of cancer undergoing neoadjuvant treatment.
DESIGN
Systematic review.
METHOD
A comprehensive search of existing literature was carried out using four electronic databases: PubMed, Scopus, Web of Science, and Cochrane Library (published until October 19, 2022). All databases were searched for randomized controlled trials, quasi-experimental investigations, and pre-post investigations assessing the effects of exercise in cancer patients during neoadjuvant treatment. Excluded articles included multicomponent interventions, such as exercise plus diet or behavioral therapy, and investigations performed during adjuvant treatment or survivorship. The methodological quality of each study was assessed using the Physiotherapy Evidence Database (PEDro) scale.
RESULTS
Twenty-seven trials involving 999 cancer patients were included in this review. The interventions were conducted in cancer patients undergoing neoadjuvant treatment for rectal (n = 11), breast (n = 5), pancreatic (n = 4), esophageal (n = 3), gastro-esophageal (n = 2), and prostate (n = 1) cancers, and leukemia (n = 1). Among the investigations included, 14 utilized combined exercise protocols, 11 utilized aerobic exercise, and two utilized both aerobic and resistance training separately. Exercise interventions appeared to improve cardiorespiratory fitness, muscle strength, body composition, and quality of life, although many investigations lacked a between-group analysis.
CONCLUSION
Despite limited evidence, exercise interventions applied during neoadjuvant treatment demonstrate promising potential in enhancing cardiorespiratory fitness, muscle strength, body composition, and overall quality of life. However, a scarcity of evidence remains on the effects of exercise on cancer-related fatigue and sleep quality. Further research with high-quality randomized controlled trials is warranted.
