Meta-Analysis Review
BACKGROUND
Ultrasound and liver function tests (serum bilirubin and serum alkaline phosphatase) are used as screening tests for the diagnosis of common bile duct stones in people suspected of having common bile duct stones. There has been no systematic review of the diagnostic accuracy of ultrasound and liver function tests.
OBJECTIVES
To determine and compare the accuracy of ultrasound versus liver function tests for the diagnosis of common bile duct stones.
SEARCH METHODS
We searched MEDLINE, EMBASE, Science Citation Index Expanded, BIOSIS, and Clinicaltrials.gov to September 2012. We searched the references of included studies to identify further studies and systematic reviews identified from various databases (Database of Abstracts of Reviews of Effects, Health Technology Assessment, Medion, and ARIF (Aggressive Research Intelligence Facility)). We did not restrict studies based on language or publication status, or whether data were collected prospectively or retrospectively.
SELECTION CRITERIA
We included studies that provided the number of true positives, false positives, false negatives, and true negatives for ultrasound, serum bilirubin, or serum alkaline phosphatase. We only accepted studies that confirmed the presence of common bile duct stones by extraction of the stones (irrespective of whether this was done by surgical or endoscopic methods) for a positive test result, and absence of common bile duct stones by surgical or endoscopic negative exploration of the common bile duct, or symptom-free follow-up for at least six months for a negative test result as the reference standard in people suspected of having common bile duct stones. We included participants with or without prior diagnosis of cholelithiasis; with or without symptoms and complications of common bile duct stones, with or without prior treatment for common bile duct stones; and before or after cholecystectomy. At least two authors screened abstracts and selected studies for inclusion independently.
DATA COLLECTION AND ANALYSIS
Two authors independently collected data from each study. Where meta-analysis was possible, we used the bivariate model to summarise sensitivity and specificity.
MAIN RESULTS
Five studies including 523 participants reported the diagnostic accuracy of ultrasound. One studies (262 participants) compared the accuracy of ultrasound, serum bilirubin and serum alkaline phosphatase in the same participants. All the studies included people with symptoms. One study included only participants without previous cholecystectomy but this information was not available from the remaining studies. All the studies were of poor methodological quality. The sensitivities for ultrasound ranged from 0.32 to 1.00, and the specificities ranged from 0.77 to 0.97. The summary sensitivity was 0.73 (95% CI 0.44 to 0.90) and the specificity was 0.91 (95% CI 0.84 to 0.95). At the median pre-test probability of common bile duct stones of 0.408, the post-test probability (95% CI) associated with positive ultrasound tests was 0.85 (95% CI 0.75 to 0.91), and negative ultrasound tests was 0.17 (95% CI 0.08 to 0.33).The single study of liver function tests reported diagnostic accuracy at two cut-offs for bilirubin (greater than 22.23 μmol/L and greater than twice the normal limit) and two cut-offs for alkaline phosphatase (greater than 125 IU/L and greater than twice the normal limit). This study also assessed ultrasound and reported higher sensitivities for bilirubin and alkaline phosphatase at both cut-offs but the specificities of the markers were higher at only the greater than twice the normal limit cut-off. The sensitivity for ultrasound was 0.32 (95% CI 0.15 to 0.54), bilirubin (cut-off greater than 22.23 μmol/L) was 0.84 (95% CI 0.64 to 0.95), and alkaline phosphatase (cut-off greater than 125 IU/L) was 0.92 (95% CI 0.74 to 0.99). The specificity for ultrasound was 0.95 (95% CI 0.91 to 0.97), bilirubin (cut-off greater than 22.23 μmol/L) was 0.91 (95% CI 0.86 to 0.94), and alkaline phosphatase (cut-off greater than 125 IU/L) was 0.79 (95% CI 0.74 to 0.84). No study reported the diagnostic accuracy of a combination of bilirubin and alkaline phosphatase, or combinations with ultrasound.
AUTHORS' CONCLUSIONS
Many people may have common bile duct stones in spite of having a negative ultrasound or liver function test. Such people may have to be re-tested with other modalities if the clinical suspicion of common bile duct stones is very high because of their symptoms. False-positive results are also possible and further non-invasive testing is recommended to confirm common bile duct stones to avoid the risks of invasive testing.It should be noted that these results were based on few studies of poor methodological quality and the results for ultrasound varied considerably between studies. Therefore, the results should be interpreted with caution. Further studies of high methodological quality are necessary to determine the diagnostic accuracy of ultrasound and liver function tests.

Meta-Analysis Review
AIM
To assess the rate of bile duct injuries (BDI) and overall biliary complications during single-port laparoscopic cholecystectomy (SPLC) compared to conventional laparoscopic cholecystectomy (CLC).
METHODS
SPLC has recently been proposed as an innovative surgical approach for gallbladder surgery. So far, its safety with respect to bile duct injuries has not been specifically evaluated. A systematic review of the literature published between January 1990 and November 2012 was performed. Randomized controlled trials (RCT) comparing SPLC versus CLC reporting BDI rate and overall biliary complications were included. The quality of RCT was assessed using the Jadad score. Analysis was made by performing a meta-analysis, using Review Manager 5.2. This study was based on the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. A retrospective study including all retrospective reports on SPLC was also performed alongside.
RESULTS
From 496 publications, 11 RCT including 898 patients were selected for meta-analysis. No studies were rated as high quality (Jadad score ≥ 4). Operative indications included benign gallbladder disease operated in an elective setting in all studies, excluding all emergency cases and acute cholecystitis. The median follow-up was 1 mo (range 0.03-18 mo). The incidence of BDI was 0.4% for SPLC and 0% for CLC; the difference was not statistically different (P = 0.36). The incidence of overall biliary complication was 1.6% for SPLC and 0.5% for CLC, the difference did not reached statistically significance (P = 0.21, 95%CI: 0.66-15). Sixty non-randomized trials including 3599 patients were also analysed. The incidence of BDI reported then was 0.7%.
CONCLUSION
The safety of SPLC cannot be assumed, based on the current evidence. Hence, this new technology cannot be recommended as standard technique for laparoscopic cholecystectomy.

Review
OBJECTIVES
To assess through literature case analysis how advances in lymphatic imaging, interventional radiology, and lymphatic vascular microsurgery illuminate and improve the lymphatic-flow status in select patients with Noonan syndrome (NS) who have undergone surgical intervention as a part of their comprehensive and individualized treatment plan. Also, we sought to illustrate the spectrum of lymphatic complications that can occur in this patient population when lymphatic flow through abnormal vasculature is surgically disrupted.
METHODS
A literature review was performed by searching "Noonan AND Lymphatic AND Imaging" in the PubMed database. Inclusion criteria for this study were (1) diagnosis and clinical description of at least one original patient with NS, (2) imaging figures depicting lymphatic structure and function or a description of lymphatic imaging findings when a figure is not present, and (3) documentation of either lymphatic surgical intervention or lymphatic complications resulting from other procedures. Patient cases were first grouped by documented surgical intervention type, then clinical outcomes and lymphatic imaging results were compared.
RESULTS
A total of 18 patient cases from 10 eligible publications were included in our review. Lymphatic imaging findings across all patients included lymphatic vessel dysplasia along with flow disruption (n = 16), thoracic duct malformations (n = 12), dermal lymphatic reflux (n = 7), and dilated lymphatic vessels (n = 4). Lymphovenous anastomosis (n = 4) resulted in rapid improvement of patient symptoms and signs. New-onset lymphatic manifestations noted over 10 to 20 years for two of these patients were chylothorax (n = 1), erysipelas (n = 1), and gradual-onset nonchylous scrotal lymphorrhea (n = 1). Targeted endovascular lymphatic disruption via sclerosis, embolization, or ablation (n = 8) results were mixed depending on the degree of central lymphatic involvement and included resolution of symptoms (n = 1), postoperative abdominal hemorrhage (n = 1), stable condition or minor improvement (n = 5), and death (n = 2). Large lymphatic vessel ligation or accidental incision (n = 6) occurred during thoracotomy (n = 4), scrotoplasty (n = 1), or inguinal lymph node biopsy (n = 1). These resulted in postoperative onset of new-onset regional lymphatic reflux (n = 5), chylothorax (n = 4), death (n = 3), or persistent or unchanged symptoms (n = 1).
CONCLUSIONS
Imaging of the central lymphatics enabled characterization of lymphatic developmental features and guided operative management of lymphatic vascular defects in patients with NS. This review of the literature suggests that the surgical preservation or enhancement of central lymphatic return in patients with NS may improve interventional outcomes, whereas the disruption of central lymph flow has significant potential to cause severe postoperative complications and worsening of the patient's clinical condition.

BACKGROUND
The occurrence of a cluster of occupational cholangiocarcinoma(CCA) cases among Japanese workers at a small offset printing plant led to the hypotheses that occupational exposure was the root cause of this cancer. Numerous workplace carcinogens can be found at various jobs sites and are integral to various industrial processes. Therefore, a systematic evaluation of potential occupationally-related CCA and likely exposure types is needed.
OBJECTIVE
To conduct a systematic review on the cause of CCA in relation to occupation.
METHODS
The systematic review included papers published between 1980 and 2020. Databases included PubMed, Science Direct, CINAHL, ProQuest Medical Library, Springer, Wiley online library, and the Cochrane library. The review focused on CCA, intrahepatic CCA(as distinct from other types of liver cancer), and extrahepatic CCA(not including the gallbladder). While some occupations involve an expected risk of exposure to carcinogens, this study sought both primary reports on specific carcinogens or surrogates by occupation or industry title. Of the 65 English version abstracts, 18 studies were selected for in-depth review according to the eligibility criteria. Two occupational physicians independently assessed the relevance to the study objectives, data extractability, and data quality as per the Newcastle-Ottawa Scale.
RESULTS
The review revealed that ten observational studies met the eligibility criteria. There was heterogeneity of occupational exposure assessment and the reported results. The possible carcinogens statistical significantly related to the incidence or mortality of CCA risk included 1,2-dichloropropane (the highest RR = 32.40, 95%CI=6.40-163.90), asbestos (the highest OR=4.81, 95 % CI =1.73-13.33), endocrine-disrupting compounds (the highest OR =2.00, 95% CI=1.10-3.70), and rotating shift work (the highest HR =1.97, 95%CI=1.02-3.79). These carcinogens are classified as IARC class 1 and 2A.
CONCLUSIONS
Despite the limited number of studies reviewed, the hypothesis of occupational risk for CCA was supported. Occupational health and safety measures may decrease exposure to these carcinogens, and surveillance in high-risk occupations or industries is urgently needed to prevent and control CCA.

Review
Gastrointestinal cancer (GI) is a major health problem. Patients with gastric, pancreatic, colorectal, bile duct and gall bladder cancer often have advanced disease at the time of diagnosis and are generally difficult to cure, resulting in a dismal prognosis for most patients. Inflammation plays an important role in the development and growth of cancer, which has led to a growing interest in the pro-inflammatory cytokine interleukin 6 (IL-6). The aim of the present review was to evaluate the clinical use of IL-6 as a biomarker or therapeutic target in patients with GI cancer. We did a systematic review of studies (1993-2018), to assess the clinical use of IL-6 as a diagnostic, prognostic or predictive tumor biomarker or as a potential therapeutic target. This review includes 48 studies and 5316 patients. Circulating IL-6 levels appear to be an independent prognostic biomarker in patients with GI cancer, with high IL-6 levels associated with short overall survival (OS). The results for colorectal cancer were too ambiguous to give conclusive results. IL-6 seemed to be a marker for some of the clinical characteristics of GI cancer, and may have a role in the diagnostic workup in general practice. No published studies have examined the use of IL-6 as a therapeutic target in pancreatic, gastric, bile duct or colorectal cancer. In conclusion, high circulating IL-6 was associated with short OS in most studies in GI cancer patients. Whether inhibition of IL-6 would decrease GI cancer symptoms and increase quality of life is unknown.

Meta-Analysis
BACKGROUND
Several comparative studies have shown that endoscopic balloon dilation (EPBD) combined with endoscopic sphincterotomy (EST) may be a better choice than EPBD alone for the treatment of common bile duct stones (CBDS). However, there are limited data that can be used to compare this combination method with EST or EPBD alone in the treatment of choledocholithiasis. Therefore, this study aimed to systematically evaluate the efficacy of EPBD alone and EPBD combined with EST in the treatment of CBDS.
METHODS
We performed a literature search of the PubMed, Cochrane Central Register of Controlled Trials, Embase, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang, and Weipu databases using the following search terms: endoscopic balloon dilation, endoscopic sphincterotomy, sphincterotomy, balloon dilation, gallstones, bile duct stones, and common bile duct stones. The Cochrane risk of bias tool was used to evaluate the quality of the included studies, and the network meta-analysis was performed using RevMan 5.20.
RESULTS
A total of nine articles satisfied the inclusion criteria, involving 497 patients who received EST + EPBD and 548 patients who underwent EPBD alone. The results of the meta-analysis showed that compared with the EPBD group, the EST + EPBD group had significant differences in the stone removal time [mean difference (MD) is -1.83; 95% confidence interval (CI): (-3.57, -0.10)] and the initial stone removal rate [relative risk (RR) is 1.11; 95% CI: (1.04, 1.19)]. There were no significant differences in the rate of mechanical vibration stone crushing [RR is 0.74; 95% CI: (0.55, 1.00)], total rate of stone removal [RR is 1.01; 95% CI: (0.98, 1.04)], and complication rate [RR is 0.87; 95% CI: (0.66, 1.13)].
DISCUSSION
The stone removal time and initial stone removal rate of patients in the EST + EPBD group were superior to those of patients in the EPBD group, and the two groups were similar in terms of total stone removal success rate, mechanical lithotripsy (ML) rate, and complication rate. Therefore, large-scale, multi-center prospective studies are needed to clarify whether EST + EPBD is superior to EPBD alone in the treatment of choledocholithiasis.

Meta-Analysis
How should we secure the cystic duct during laparoscopic cholecystectomy? A UK-wide survey of clinical practice and systematic review of the literature with meta-analysis.
INTRODUCTION
It is currently unknown which method of cystic duct closure is most effective at reducing the risk of bile leak after laparoscopic cholecystectomy. The aims of this work were to determine the most common closure methods used in the UK and review available evidence on which method has the lowest risk of bile leak.
METHODS
We conducted an online survey through the Association of Upper Gastrointestinal Surgeons (AUGIS). We also undertook a systematic review using PubMed, EMBASE, MEDLINE and the Cochrane Library for studies that compared different methods for cystic duct occlusion and reported postoperative bile leak.
FINDINGS
There was significant variation in practice between consultant surgeons. For routine laparoscopic cholecystectomy metal clips were used most (64%) followed by locking polymer clips (33%) and suture ties (3%). In cases of a dilated cystic duct, preferences were locking polymer clips (60%), suture ties (30%) and metal clips (5%). We included six studies in our review with a total of 8,011 patients. Metal clips were associated with an increased odds of bile leak compared with locking polymer clips (OR 5.66, 95% CI 1.13-28.41, =0.04) or suture ties (OR 4.17, 95% CI 0.72-24.31, =0.12). Most studies were retrospective, unlikely to be adequately powered, and vulnerable to selection bias.
CONCLUSIONS
Limited available evidence suggests that metal clips have the highest risk of bile leak, but results are not strong enough to recommend a change in current clinical practice. A trial is now required to determine the best method of cystic duct closure.

Review
Comparison of endoscopic papillary large balloon dilation with and without a prior endoscopic sphincterotomy for the treatment of patients with large and/or multiple common bile duct stones: a systematic review and meta-analysis.
AIM
To compare endoscopic papillary large balloon dilation (EPLBD) alone with EPLBD following endoscopic sphincterotomy (EST) in patients with large and/or multiple common bile duct stones.
METHODS
We conducted a comprehensive search of PubMed, EMBASE, and the Cochrane Library database to identify relevant available articles until July 19, 2018. Complete common bile duct stone (CBDS) removal rate, frequency of mechanical lithotripsy (ML) usage, total procedure time and intra- and postoperative adverse events were analyzed. We used RevMan 5.3 to perform the pooled analyses.
RESULTS
Seven RCTs matched the selection criteria. A total of 369 patients underwent EPLBD alone, and 367 patients underwent EPLBD following EST. Our meta-analysis revealed that there were no significant differences in terms of initial success rate (OR =0.69, 95% CI=0.44-1.09, =0.11), frequency of ML usage (OR =1.18, 95% CI=0.68-2.05, =0.55), rate of post-endoscopy pancreatitis (PEP) (OR =0.88, 95% CI=0.43-1.78, =0.72), total procedure time (MD =1.52, 95% CI=-0.13-3.17, =0.07), or other intra- and postoperative adverse events between the groups for patients with large and/or multiple CBDSs.
CONCLUSIONS
EPLBD alone was comparable to EPLBD with prior EST in patients with large and/or multiple CBDSs. Further studies are required to confirm the mechanisms of PEP in patients who accept EPLBD during endoscopic retrograde cholangiopancreatography (ERCP).

Meta-Analysis Review
BACKGROUND
Congenital nasolacrimal duct obstruction (NLDO) is a common condition causing excessive tearing in the first year of life. Infants present with excessive tearing or mucoid discharge from the eyes due to blockage of the nasolacrimal duct system, which can result in maceration of the skin of the eyelids and local infections, such as conjunctivitis, that may require antibiotics. The incidence of nasolacrimal duct obstruction in early childhood ranges from 5% to 20% and often resolves without surgery. Treatment options for this condition are either conservative therapy, including observation (or deferred probing), massage of the lacrimal sac and antibiotics, or probing the nasolacrimal duct to open the membranous obstruction at the distal nasolacrimal duct. Probing may be performed without anesthesia in the office setting or under general anesthesia in the operating room. Probing may serve to resolve the symptoms by opening the membranous obstruction; however, it may not be successful if the obstruction is due to a bony protrusion of the inferior turbinate into the nasolacrimal duct or when the duct is edematous (swollen) due to infection such as dacryocystitis. Additionally, potential complications with probing include creation of a false passage and injury to the nasolacrimal duct, canaliculi and puncta, bleeding, laryngospasm, or aspiration.
OBJECTIVES
To assess the effects of probing for congenital nasolacrimal duct obstruction.
SEARCH METHODS
We searched the Cochrane Central Register of Controlled Trials (CENTRAL), which contains the Cochrane Eyes and Vision Trials Register (2016, Issue 8); MEDLINE Ovid (1946 to 30 August 2016); Embase.com (1947 to 30 August 2016); PubMed (1948 to 30 August 2016); LILACS (Latin American and Caribbean Health Sciences Literature Database; 1982 to 30 August 2016), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com), last searched 14 August 2014; ClinicalTrials.gov (www.clinicaltrials.gov), searched 30 August 2016; and the WHO International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en), searched 30 August 2016. We did not use any date or language restrictions in the electronic searches for trials.
SELECTION CRITERIA
We included randomized controlled trials (RCTs) that compared probing (office-based or hospital-based under general anesthesia) versus no (or deferred) probing or other interventions (observation alone, antibiotic drops only, or antibiotic drops plus massage of the nasolacrimal duct). We did not include studies that compared different probing techniques or probing compared with other surgical procedures. We included studies in children aged three weeks to four years who may have presented with tearing and conjunctivitis.
DATA COLLECTION AND ANALYSIS
Two review authors independently screened studies for inclusion and independently extracted data and assessed risk of bias for the included studies. We analyzed data using Review Manager software and evaluated the certainty of the evidence using GRADE.
MAIN RESULTS
We identified two RCTs and no ongoing studies; one of the included RCTs was registered. The studies reported on 303 eyes of 242 participants who had unilateral or bilateral congenital nasolacrimal duct obstruction. For both included studies, the interventions compared were immediate office-based probing to remove the duct obstruction versus deferred probing, if needed, after 6 months of observation or once the child reached a certain age.The primary outcome of the review, treatment success at 6 months, was reported partially in one study. Treatment success was not reported at this time point for all children in the immediate probing group; however, 77 of 117 (66%) eyes randomized to deferred probing had resolved without surgery 6 months after randomization and 40 (34%) eyes did not resolve without probing. For children who had unilateral NLDO, those randomized to immediate probing had treatment success more often than those who were randomized to deferred probing (RR 1.41, 95% CI 1.12 to 1.78; 163 children; moderate-certainty evidence). Treatment success for all children was assessed in the study at age 18 months; as an ad hoc analysis in the included study, results were presented separately for children with unilateral and bilateral NLDO (RR 1.13, 95% CI 0.99 to 1.28 and RR 0.86, 95% CI 0.70 to 1.06, respectively; very low-certainty evidence).In the other small study (26 eyes of 22 children), more eyes that received immediate probing were cured within one month after surgery compared with eyes that were randomized to deferred probing and analyzed at age 15 months (RR 2.56, 95% CI 1.16 to 5.64). We considered the evidence to be low-certainty due to imprecision from the small study size and risk of bias concerns due to attrition bias.One study reported on the number of children that required reoperation; however, these data were reported only for immediate probing group. Nine percent of children with unilateral NLDO and 13% with bilateral NLDO required secondary procedures.One study reported cost-effectiveness of immediate probing versus deferred probing. The mean cost of treatment for immediate probing was less than for deferred probing; however, there is uncertainty as to whether there is a true cost difference (mean difference USD -139, 95% CI USD -377 to 94; moderate-certainty evidence).Reported complications of the treatment were not serious. One study reported that there were no complications for any surgery and no serious adverse events, while the other study reported that bleeding from the punctum occurred in 20% of all probings.
AUTHORS' CONCLUSIONS
The effects and costs of immediate versus deferred probing for NLDO are uncertain. Children who have unilateral NLDO may have better success from immediate office probing, though few children have participated in these trials, and investigators examined outcomes at disparate time points. Determining whether to perform the procedure and its optimal timing will require additional studies with greater power and larger, well-run clinical trials to help our understanding of the comparison.

Pain is the most frequent and dominant symptom of chronic pancreatitis. Currently, these patients are treated using a step-up approach, including analgesics and lifestyle adjustments, endoscopic, and eventually surgical treatment. Extracorporeal shock wave lithotripsy (ESWL) is indicated after failure of the first step in patients with symptomatic intraductal stones larger than 5 mm in the head or body of the pancreas. To assess the complete ductal clearance rate and pain relief after ESWL in patients with symptomatic chronic pancreatitis with pancreatic duct stones, a systematic review and meta-analysis was performed. A systematic literature search from January 2000 to December 2018 was performed in PubMed, the Cochrane Library, and EMBASE for studies on ductal clearance rate of ESWL in patients with symptomatic chronic pancreatitis with pancreatic duct stones. After screening 486 studies, 22 studies with 3868 patients with chronic pancreatitis undergoing ESWL for pancreatic duct stones were included. The pooled proportion of patients with complete ductal clearance was 69.8 % (95 % CI 63.8-75.5). The pooled proportion of complete absence of pain during follow-up was 64.2 % (95 % CI 57.5-70.6). Complete stone fragmentation was 86.3 % (95 % CI 76.0-94.0). Post-procedural pancreatitis and cholangitis occurred in 4.0 % (95 % CI 2.5-5.8) and 0.5 % (95 % CI 0.2-0.9), respectively. Treatment with ESWL results in complete ductal clearance rate in a majority of patients, resulting in absence of pain during follow up in over half of patients with symptomatic chronic pancreatitis caused by obstructing pancreatic duct stones.
