Review
INTRODUCTION
Warts are caused by the human papillomavirus (HPV), of which there are over 100 types, which probably infects the skin via areas of minimal trauma. Risk factors include use of communal showers, occupational handling of meat, and immunosuppression. In immunocompetent people, warts are harmless and resolve as a result of natural immunity within months or years.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical question: What are the effects of treatments for warts (non-genital)? We searched: Medline, Embase, The Cochrane Library, and other important databases up to June 2008 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
RESULTS
We found 12 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
CONCLUSIONS
In this systematic, review we present information relating to the effectiveness and safety of the following interventions: intralesional bleomycin; cimetidine; contact immunotherapy; cryotherapy; duct tape occlusion; formaldehyde, glutaraldehyde; homeopathy; photodynamic treatment; pulsed dye laser; surgical procedures; topical salicylic acid; and zinc sulphate.

Review
Pneumoparotid describes retrogradely insufflated air within the Stensen's duct and/or parotid gland. It is a rare condition with variable causative factors. This study aimed to elucidate the clinical characteristics of pneumoparotid. Reports in all languages were evaluated following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement 2020. A literature search was conducted using electronic medical databases (PubMed, Scopus, Web of Science, EBSCO, Ovid, Google Scholar, SciElo, LILIACS, and others) from 1890 to 30 June 2022. One hundred and seventy patients (mean age; 28.4 years) from 126 studies were reviewed. Common symptoms included swelling (84.7%) and pain (35.9%). Characteristic findings were crepitus in the parotid region (40%) and frothy saliva from the orifice (39.4%). The common etiologies included abnormal habits such as blowing out the cheeks (23.5%), idiopathic (20%), self-induced (15.9%), playing wind instruments such as trumpets or flutes (8.8%), and diseases inducing coughing or sneezing (8.2%). The treatments included antibiotic therapy (30%), behavioral therapy to avoid continuing causative habits (25.9%), psychiatric therapy (8.2%), and surgical procedures (8.2%). Treatment should be individualized and etiology-based. However, the etiology was not identified in 20% of patients. Further detailed data from larger samples are required to clarify and improve the recognition of this entity.

Review
BACKGROUND
The primary therapeutic strategy for the management of bile duct stones (BDS) is endoscopic retrograde cholangiopancreatography. However, there may be a recurrence of BDS on follow-up. Multiple risk factors have been studied for the prediction of BDS recurrence. We aimed to analyze the incidence of symptomatic BDS recurrence, systematically review the risk factors, and analyze the most important risk factors among those.
METHODS
A comprehensive search of three databases was conducted from inception to November 2022 for studies reporting the recurrence of BDS recurrence after endoscopic retrograde cholangiopancreatography with clearance, along with an analysis of risk factors.
RESULTS
A total of 37 studies with 12,952 patients were included in the final analysis. The pooled event rate for the recurrence of BDS stones was 12.6% (95% confidence interval: 11.2-13.9). The most important risk factor was a bile duct diameter ≥15 mm, which had a significant association with recurrence in twelve studies. Other risk factors with significant association with recurrence in three or more studies were the reduced angulation of the bile duct, the presence of periampullary diverticulum, type I periampullary diverticulum, in-situ gallbladder with stones, cholecystectomy, multiple stones in the bile duct, use of mechanical lithotripsy, and bile duct stent placement.
CONCLUSION
Around one out of seven patients have BDS recurrence after the initial endoscopic retrograde cholangiopancreatography. Bile duct size and anatomy are the most important predictors of recurrence. The assessment of risk factors associated with recurrence may help keep a close follow-up in high-risk patients.

Review
BACKGROUND
Cholangiocarcinoma (CCA) is a common primary liver malignancy with a poor prognosis. Many studies have demonstrated the involvement of circular RNAs (circRNAs) in tumorigenesis and progression.
METHODS
Four online databases (PubMed, Web of Science, Embase, and Scopus) were searched on May 04, 2023, for original papers regarding CCA and circRNAs. Bibliometric analysis of included studies was performed on R Studio and GraphPad Prism.
RESULTS
Thirty studies were included in the systematic review and bibliometric analysis. The systematic review showed that circRNAs were involved in CCA proliferation, invasion, metastasis, chemotherapy resistance, and other biological processes and were related to the prognosis of patients and many clinicopathological features. Exosomal circRNAs provide a new idea for the early diagnosis of CCA. The bibliometric analysis showed a significant upward trend in the number of studies on CCA and circRNAs. The 30 included papers had 201 authors and were published in 22 English journals. The first paper was published in 2018, and the second paper was the most cited (148 citations).
CONCLUSION
This systematic review and bibliometric analysis demonstrates that circRNAs in CCA have not been studied enough. CircRNAs play an important role in the occurrence and progression of CCA. They may become new targets for the diagnosis, treatment, and prognostic monitoring of CCA.

Review
Placement of a covered (C)-self-expandable metal stent (SEMS) has been recently investigated as an alternative endoscopic treatment for main pancreatic duct stricture (MPDS) in chronic pancreatitis. Our aim was to carry out a systematic review and meta-analysis of studies quantifying efficacy and safety of C-SEMSs in the management of MPDS. A multiple database search was performed, including MEDLINE, Embase and Cochrane Library, from January 2000 to September 2020, to identify studies reporting the efficacy and safety of C-SEMSs in patients with MPDS. Stricture and pain resolution were investigated. Other outcomes included technical success, stent migration, stricture recurrence and need for repeated stent placement. Pancreatitis, severe abdominal pain requiring stent removal and de-novo stricture were recorded as complications. Nineteen studies were identified, which included a total of 300 patients. C-SEMSs showed a pooled stricture resolution rate of 91 % [95 % confidence interval (CI), 85 %-96 %] and a pooled pain resolution rate of 92 % (95 % CI, 85 %-98 %). The pooled proportion for stricture recurrence was equal to 6 % (95 % CI, 1 %-14 %), while stent migration occurred in 33 of 300 patients, the pooled proportion being 7 % (95 % CI 1 %-15 %). The pooled mean stent duration was 133 days (95 % CI, 100-166 days). The most common complication was pancreatitis (3 %, 95 % CI 0 %-8 %), while de-novo stricture pooled proportion was 2 % (95 % CI, 0 %-5 %). C-SEMSs are effective and safe in the treatment of MPDS. However, there is a significant need for further high-quality, well-designed studies to produce evidence-based data on short and long-term efficacy, safety, costs of C-SEMSs, and also optimal stent duration.

Meta-Analysis Review
OBJECTIVE
Duct-to-mucosa and invagination are two commonly used techniques of pancreaticojejunostomy (PJ) after pancreaticoduodenectomy. Previously, we conducted a systematic review comparing the safety and efficacy of the two PJ techniques. Here, we added new evidence and updated our previous conclusion.
METHODS
We systematically searched multiple databases and included randomized controlled trials (RCTs) comparing duct-to-mucosa and invagination techniques of PJ. The quality of evidence was assessed using Jadad score, and reporting bias was evaluated using funnel plots. Meta-analysis was performed using a random-effects model. Risk ratio (RR) and 95% confidence interval (CI) were calculated. The primary outcome was pancreatic fistula, and the secondary outcomes included mortality, reoperation, morbidity and postoperative hospital stay. Trial sequential analysis was performed to calculate the required information size.
RESULTS
Seven RCTs with 850 participants were included. No significant difference was detected in the rates of pancreatic fistula (RR 0.98, 95% CI 0.63 to 1.53), mortality (RR 0.94, 95% CI 0.40 to 2.18), reoperation (RR 1.23, 95% CI 0.69 to 2.20) and morbidity (RR 0.98, 95% CI 0.82 to 1.16) between the two groups. However, patients who underwent duct-to-mucosa PJ had a significantly shorter postoperative hospital stay (mean difference -2.80, 95% CI -5.08 to -0.52). Trial sequential analysis showed that another 279 participants were needed for conclusive results.
CONCLUSIONS
Given the current evidence, duct-to-mucosa PJ did not decrease the rates of pancreatic fistula and other adverse events as compared to invagination PJ; however, it did reduce postoperative hospital stay. Further RCTs are needed.

Review
We aim to investigate the potential of laparoscopic ultrasonography (LUS) as a replacement for intraoperative cholangiography (IOC) in the context of laparoscopic cholecystectomy focusing on various aspects related to both techniques. We made our search through PubMed, Web of Science, Cochrane Library, and Scopus, with the use of the following search strategy: ("laparoscopic ultrasonography" OR LUS OR "laparoscopic US" OR "laparoscopic ultrasound") AND ("laparoscopic cholecystectomy" OR LC). We incorporated diverse studies that addressed our topic, offering data on the identification of biliary anatomy and variations, the utilization of laparoscopic ultrasound in cholecystitis, the detection of common bile duct stones, and the criteria utilized to assess the accuracy of LUS. A total of 1526 articles were screened and only 20 were finally included. This systematic review assessed LUS and IOC techniques in cholecystectomy. IOC showed higher failure rates due to common duct catheterization challenges, while LUS had lower failure rates, often linked to factors like steatosis. Cost-effectiveness comparisons favored LUS over IOC, potentially saving patients money. LUS procedures were quicker due to real-time imaging, while IOC required more time and personnel. Bile duct injuries were discussed, highlighting LUS limitations in atypical anatomies. LUS aided in diagnosing crucial conditions, emphasizing its relevance post surgery. Surgeon experience significantly impacted outcomes, regardless of the technique. A previous study discussed that LUS's learning curve was steeper than IOC's, with proficient LUS users adjusting practices and using IOC selectively. Highlighting LUS's benefits and limitations in cholecystectomy, we stress its value in complex anatomical situations. LUS confirms no common bile duct stones, avoiding cannulation. LUS and IOC equally detect common bile duct stones and visualize the biliary tree. LUS offers safety, speed, cost-effectiveness, and unlimited use. Despite the associated expenses and learning curve, the enduring benefits of using advanced probes in LUS imaging suggest that it could surpass traditional IOC. The validation of this potential advancement relies heavily on incorporating modern probe studies. Our study could contribute to the medical literature by evaluating their clinical validity, safety, cost-effectiveness, learning curve, patient outcomes, technological advancements, and potential impact on guidelines and recommendations for clinical professionals.

Review
Per-oral pancreatoscopy (POP) with intraductal lithotripsy via electrohydraulic lithotripsy (EHL) or laser lithotripsy (LL) facilitates optically-guided stone fragmentation of difficult pancreatic stones refractory to conventional endoscopic therapy. The aim of this study was to perform a systematic review and meta-analysis to evaluate the efficacy and safety of POP with intraductal lithotripsy for difficult pancreatic duct stones. Individualized search strategies were developed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses and Meta-analysis of Observational Studies in Epidemiology guidelines. This was a cumulative meta-analysis performed by calculating pooled proportions with rates estimated using random effects models. Measured outcomes included pooled technical success, complete or partial stone fragmentation success, complete duct clearance after initial lithotripsy session, and adverse events (AEs). Ten studies (n = 302 patients; 67.72 % male; mean age 55.10 ± 3.22 years) were included with mean stone size of 10.66 ± 2.19 mm. The most common stone location was in the pancreatic head (66.17 %). Pooled technical success was 91.18 % with an overall fragmentation success of 85.77 %. Single lithotripsy session stone fragmentation and pancreatic duct clearance occurred in 62.05 % of cases. Overall, adverse events were reported in 14.09 % of patients with post-procedure pancreatitis developing in 8.73 %. Of these adverse events, 4.84 % were classified as serious. Comparing POP-EHL vs POP-LL, there was no significant difference in technical success, fragmentation success, single session duct clearance, or AEs ( > 0.0500). Based on this systematic review and meta-analysis, POP with intraductal lithotripsy appears to be an effective and relatively safe procedure for patients with difficult to remove pancreatic duct stones.

Review
Neuroendocrine tumors of the extrahepatic bile ducts (EBNETs) are very rare. The aim of the present review is to elucidate the characteristics of EBNETs, their treatment and prognosis. An exhaustive systematic review of the literature was performed from 1959 up-to-date. One hundred articles, describing 150 cases were collected. Each article was carefully analyzed and a database was created. The most common symptoms were jaundice (60.3 %) and pruritus (19.2 %). Cholelithiasis co-existed in 15 cases (19.2 %). Hormone- and vasoactive peptide- related symptoms were present in only 7 cases (9 %). The most frequent sites were found to be the common hepatic duct and the proximal common bile duct (19.2 %). Surgical management was considered the main treatment for EBNETs, while excision of extrahepatic biliary tree (62.82 %) with portal vein lymphadenectomy (43.6 %) was the most popular procedure. EBNETs are extremely rare. Their rarity makes their characterization particularly difficult. Up to date the final diagnosis is made after surgery by pathology and immunohistochemistry findings. The present analysis of the existing published cases elucidates many aspects of these tumours, giving complete clinicopathological documentation.

Meta-Analysis
BACKGROUND
Pancreatic duct stones can lead to significant abdominal pain for patients. Per oral pancreatoscopy (POP)-guided intracorporal lithotripsy is being increasingly used for the management of main pancreatic duct calculi (PDC) in chronic pancreatitis. POP uses two techniques: Electrohydraulic lithotripsy (EHL) and laser lithotripsy (LL). Data on the safety and efficacy are limited for this procedure. We performed a systematic review and meta-analysis with a primary aim to calculate the pooled technical and clinical success rates of POP. The secondary aim was to assess pooled rates of technical success, clinical success for the two individual techniques, and adverse event rates.
AIM
To perform a systematic review and meta-analysis of POP, EHL and LL for management of PDC in chronic pancreatitis.
METHODS
We conducted a comprehensive search of multiple electronic databases and conference proceedings including PubMed, EMBASE, Cochrane, Google Scholar and Web of Science databases (from 1999 to October 2019) to identify studies with patient age greater than 17 and any gender that reported on outcomes of POP, EHL and LL. The primary outcome assessed involved the pooled technical success and clinical success rate of POP. The secondary outcome included the pooled technical success and clinical success rate for EHL and LL. We also assessed the pooled rate of adverse events for POP, EHL and LL including a subgroup analysis for the rate of adverse event subtypes for POP: Hemorrhage, post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP), perforation, abdominal pain, fever and infections. Technical success was defined as the rate of clearing pancreatic duct stones and clinical success as the improvement in pain. Random-effects model was used for analysis. Heterogeneity between study-specific estimates was calculated using the Cochran statistical test and statistics. Publication bias was ascertained, qualitatively by visual inspection of funnel plot and quantitatively by the Egger test.
RESULTS
A total of 16 studies including 383 patients met the inclusion criteria. The technical success rate of POP was 76.4% (95%CI: 65.9-84.5; = 64%) and clinical success rate was 76.8% (95%CI: 65.2-85.4; = 66%). The technical success rate of EHL was 70.3% (95%CI: 57.8-80.3; = 36%) and clinical success rate of EHL was 66.5% (95%CI: 55.2-76.2; = 19%). The technical success rate of LL was 89.3% (95%CI: 70.5-96.7; = 70%) and clinical success rate of LL was 88.2% (95%CI: 66.4-96.6; = 77%). The incidence of pooled adverse events for POP was 14.9% (95%CI: 9.2-23.2; = 49%), for EHL was 11.2% (95%CI: 5.9-20.3; = 15%) and for LL was 13.1% (95%CI: 6.3-25.4; = 31%). Subgroup analysis of adverse events showed rates of PEP at 7% (95%CI: 3.5-13.6; = 38%), fever at 3.7% (95%CI: 2-6.9; = 0), abdominal pain at 4.7% (95%CI: 2.7-7.8; = 0), perforation at 4.3% (95%CI: 2.1-8.4; = 0), hemorrhage at 3.4% (95%CI: 1.7-6.6; = 0) and no mortality. There was evidence of publication bias based on funnel plot analysis and Egger's test.
CONCLUSION
Our study highlights the high technical and clinical success rates for POP, EHL and LL. POP-guided lithotripsy could be a viable option for management of chronic pancreatitis with PDC.
