Comparative Study Meta-Analysis
Comparison of Efficacy and Safety of 4 Combinations of Laparoscopic and Intraoperative Techniques for Management of Gallstone Disease With Biliary Duct Calculi: A Systematic Review and Network Meta-analysis.
IMPORTANCE
Several techniques are used for surgical treatment of gallstone disease with biliary duct calculi, but the safety and efficacy of these approaches have not been compared.
OBJECTIVES
To compare the efficacy and safety of 4 surgical approaches to gallstone disease with biliary duct calculi.
DATA SOURCES
MEDLINE, Scopus, and ISI-Web of Science databases, articles published between 1950 and 2017 and searched from August 12, 2017, to September 14, 2017. Search terms used were LCBDE, LC, preoperative, ERCP, postoperative, period, cholangiopancreatography, endoscopic, retrograde, rendezvous, intraoperative, one-stage, two-stage, single-stage, gallstone, gallstones, calculi, stone, therapy, treatment, therapeutics, surgery, surgical, procedures, clinical trials as topic, random, and allocation in several logical combinations.
STUDY SELECTION
Randomized clinical trials comparing at least 2 of the following strategies: preoperative endoscopic retrograde cholangiopancreatography (PreERCP) plus laparoscopic cholecystectomy (LC); LC with laparoscopic common bile duct exploration (LCDBE); LC plus intraoperative endoscopic retrograde cholangiopancreatography (IntraERCP); and LC plus postoperative ERCP (PostERCP).
DATA EXTRACTION AND SYNTHESIS
A frequentist random-effects network meta-analysis was performed. The surface under the cumulative ranking curve (SUCRA) was used to show the probability that each approach would be the best for each outcome.
MAIN OUTCOMES AND MEASURES
Primary outcomes were the safety to efficacy ratio using overall mortality and morbidity rates as the main indicators of safety and the success rate as an indicator of efficacy. Secondary outcomes were acute pancreatitis, biliary leak, overall bleeding, operative time, length of hospital stay, total cost, and readmission rate.
RESULTS
The 20 trials comprised 2489 patients (and 2489 procedures). Laparoscopic cholecystectomy plus IntraERCP had the highest probability of being the most successful (SUCRA, 87.2%) and safest (SUCRA, 69.7%) with respect to morbidity. All approaches had similar results regarding overall mortality. Laparoscopic cholecystectomy plus LCBDE was the most successful for avoiding overall bleeding (SUCRA, 83.3%) and for the shortest operative time (SUCRA, 90.2%) and least total cost (SUCRA, 98.9%). Laparoscopic cholecystectomy plus IntraERCP was the best approach for length of hospital stay (SUCRA, 92.7%). Inconsistency was found in operative time (indirect estimate, 19.05; 95% CI, 2.44-35.66; P = .02) and total cost (indirect estimate, 17.06; 95% CI, 3.56-107.21; P = .04). Heterogeneity was observed for success rate (τ, 0.8), operative time (τ, >1), length of stay (τ, >1), and total cost (τ, >1).
CONCLUSIONS AND RELEVANCE
The combined LC and IntraERCP approach had the greatest odds to be the safest and appears to be the most successful. Laparoscopic cholecystectomy plus LBCDE appears to reduce the risk of acute pancreatitis but may be associated with a higher risk of biliary leak.

BACKGROUND & AIMS
Cholangiocarcinoma (CCA) carries a poor prognosis, is increasing in incidence and its causes are poorly understood. Although some risk factors are known, they vary globally and collectively account for a minority of cases. The aim of this study was to perform a comprehensive meta-analysis of risk factors for intrahepatic (iCCA) and extrahepatic cholangiocarcinoma (eCCA), from Eastern and Western world studies.
METHODS
A literature search of case-control studies was performed to identify potential risk factors for iCCA and eCCA. Pooled odds ratios (ORs) with 95% CIs and heterogeneity were calculated. Funnel plots were used to assess publication bias, and meta-regression was used to select risk factors for comparison between Eastern and Western studies.
RESULTS
A total of 13 risk factors were selected from 25 case-control studies in 7 geographically diverse countries. The strongest risk factors for both iCCA and eCCA were biliary cysts and stones, cirrhosis, hepatitis B and hepatitis C. Choledochal cysts conferred the greatest risk of both iCCA and eCCA with pooled ORs of 26.71 (95% CI 15.80-45.16) and 34.94 (24.36-50.12), respectively. No significant associations were found between hypertension and obesity for either iCCA or eCCA. Comparing Eastern and Western populations, there was a difference for the association of hepatitis B with iCCA (coefficient = -0.15195; 95% CI -0.278 to -0.025; p = 0.022).
CONCLUSION
This is the most comprehensive meta-analysis of CCA risk factors to date. Some risk factors, such as diabetes, although less strong, are increasing globally and may be contributing to rising rates of this cancer.
LAY SUMMARY
Cholangiocarcinoma (CCA) is a cancer arising in the bile ducts inside (intrahepatic CCA) and connected to the liver (extrahepatic CCA). It is a very aggressive cancer: 95% of patients die within 5 years. CCA rates are increasing globally, but the causes of CCA are poorly understood. The few risk factors that are known account for only a minority of cases. In this study, we found that the strongest risk factors for both intrahepatic and extrahepatic CCA are cysts and stones in the bile ducts, cirrhosis, and hepatitis B and C viruses. Some risk factors for CCA, such as diabetes, although less strong, are increasing globally and may be contributing to rising rates of CCA.

Veterinary Surgery : VS Jan 2020To evaluate the evidence published on the treatment of idiopathic chylothorax (IC) in small animals.
OBJECTIVE
To evaluate the evidence published on the treatment of idiopathic chylothorax (IC) in small animals.
STUDY DESIGN
Systematic literature review.
SAMPLE POPULATION
Dogs and cats with IC.
METHODS
A literature search was performed in three bibliographic databases in July 2018 for publications on IC in dogs and cats. Articles meeting criteria for inclusion were evaluated for treatment, survival, outcome data, and level of evidence (LoE) with a modified Oxford Level of Evidence (mOLE) and GRADE (Grading of Recommendations, Assessment, Development and Evaluations) system.
RESULTS
Eleven of 313 identified articles met the inclusion criteria. Only one study was identified in dogs as having higher LoE by using the mOLE system, whereas no study was identified as such in either species with the GRADE system. Surgery was the primary treatment in all dogs and in 93% (68/73) of cats. Medical therapy was the primary treatment in 7% (5/73) of cats. The most common surgical treatment combined thoracic duct ligation (TDL) and subtotal pericardiectomy (SP; 40%; 34/84) in dogs and TDL in cats (51% [37/73]).
CONCLUSION
The body of literature for IC treatment in small animals was limited to one higher LoE study in dogs and none in cats. No strong conclusion could be drawn regarding the effectiveness of any one surgical method in dogs or cats, and no evidence was found to support medical therapy as a primary treatment.
CLINICAL SIGNIFICANCE
The best available evidence regarding the treatment of IC is published in dogs and provides some support for surgical treatment with either TDL + cisterna chyli ablation or TDL + SP. Additional evidence is required to confirm this finding.

Review
Biliary duct hamartomas are benign intrahepatic bile duct lesions. Despite being primarily incidental findings on imaging, these lesions can provide a diagnostic conundrum due to their shared characteristics with malignant tumors. The goal of this systematic review is to offer a thorough clinical profile of biliary duct hamartomas. There were 139 cases of biliary duct hamartomas identified in a structured systematic review of the literature. Patient demographics, clinical presentation, significant laboratory and imaging data, diagnostic modalities, treatment choices, and outcomes were all studied and reported. Biliary duct hamartomas present with mild symptoms and laboratory abnormalities, and while being visible on imaging, the results are non-specific and may require biopsy in case of red flag signs such as weight loss and a progressive increase in the size of the lesion. Furthermore, there are currently no published guidelines for the treatment of biliary duct hamartomas, and many people have had surgery despite the clinically benign nature of these abnormalities. As per the findings of the study, individuals who exhibit signs of malignancy should be investigated further. Eyeballing for red flag symptoms, followed by a specialized imaging scan and invasive treatment, is the three-step approach to biliary duct hamartomas. Since our recommendations include a shift in strategy and do not contradict existing rules, there are likely to be few roadblocks to improvement; the key barriers being technological equipment and image quality. In this study, we intended to pave the way for future research in the field. In our opinion, the next decade will bring a better understanding of the characteristics of biliary hamartomas, disease symptoms, and better recognition of any suspicious features. These indications will aid in reducing the number of unneeded surgical or invasive operations. Finally, the findings of these future studies will allow the medical community to improve and provide the best care possible.

Meta-Analysis
BACKGROUND
Timely management is critical for treating symptomatic common bile duct (CBD) stones; however, a single optimal management strategy has yet to be defined in the acute care setting. Consequently, this systematic review and network meta-analysis, comparing one-stage (CBD exploration or intraoperative endoscopic retrograde cholangiopancreatography [ERCP] with simultaneous cholecystectomy) and two-stage (precholecystectomy or postcholecystectomy ERCP) procedures, was undertaken with the main outcomes of interest being postprocedural complications and hospital length of stay (LOS).
METHODS
PubMed, SCOPUS, MEDLINE, Embase, and Cochrane Central Register of Controlled Trials were methodically queried for articles from 2010 to 2021. The search terms were a combination of medical subject headings terms and the subsequent terms: gallstone; common bile duct (stone); choledocholithiasis; cholecystitis; endoscopic retrograde cholangiography/ERCP; common bile duct exploration; intraoperative, preoperative, perioperative, and postoperative endoscopic retrograde cholangiography; stone extraction; and one-stage and two-stage procedure. Studies that compared two procedures or more were included, whereas studies not recording complications (bile leak, hemorrhage, pancreatitis, perforation, intra-abdominal infections, and other infections) or LOS were excluded. A network meta-analysis was conducted to compare the four different approaches for managing CBD stones.
RESULTS
A total of 16 studies (8,644 participants) addressing the LOS and 41 studies (19,756 participants) addressing postprocedural complications were included in the analysis. The one-stage approaches were associated with a decrease in LOS compared with the two-stage approaches. Common bile duct exploration demonstrated a lower overall risk of complications compared with preoperative ERCP, but there were no differences in the overall risk of complications in the remaining comparisons. However, differences in specific postprocedural complications were detected between the four different approaches managing CBD stones.
CONCLUSION
This network meta-analysis suggests that both laparoscopic CBD exploration and intraoperative ERCP have equally good outcomes and provide a preferable single-anesthesia patient pathway with a shorter overall length of hospital stay compared with the two-stage approaches.

Review
Bile leak is a rare complication after Laparoscopic Cholecystectomy. Subvesical bile duct (SVBD) injury is the second cause of minor bile leak, following the unsuccessful clipping of the cystic duct stump. The aim of this study is to pool available data on this type of biliary tree anatomical variation to summarize incidence of injury, methods used to diagnose and treat SVBD leaks after LC. Articles published between 1985 and 2021 describing SVBD evidence in patients operated on LC for gallstone disease, were included. Data were divided into two groups based on the intra or post-operative evidence of bile leak from SVBD after surgery. This systematic report includes 68 articles for a total of 231 patients. A total of 195 patients with symptomatic postoperative bile leak are included in Group 1, while Group 2 includes 36 patients describing SVBD visualized and managed during LC. Outcomes of interest were diagnosis, clinical presentation, treatment, and outcomes. The management of minor bile leak is controversial. In most of cases diagnosed postoperatevely, Endoscopic Retrograde Cholangio-Pancreatography (ERCP) is the best way to treat this complication. Surgery should be considered when endoscopic or radiological approaches are not resolutive.

Meta-Analysis Review
PURPOSE
The goal of this study is to determine if a certain revision DCR approach (external, endoscopic endonasal, laser transcanalicular) is superior to others. Additionally, this investigation evaluates the effect of the primary surgery on success of revision.
METHODS
This investigation is a systematic review and meta-analysis. All studies specifying type of primary DCR and revision DCR were included. Proportion of successes of each revision for every primary surgery was obtained from the included studies. Meta-analyses were performed to determine cumulative proportions of successes across studies.
OUTCOME MEASURES
Significant differences in the proportions yielded by meta-analysis of successes among different surgical approaches.
RESULTS
The type of primary surgery did not significantly influence overall revision success if the same procedure was used for the revision. Overall successes per each revision type were not significantly different. When performing subgroup analyses per each primary surgery, all methods of revisions were similar in efficacy with one exception: when the primary surgery was done using the laser transcanalicular approach, external revision outperformed repetition of the primary method.
CONCLUSIONS
Regarding success of re-operation, surgeons can use the method they are most comfortable with to perform DCR revisions. However, primary transcanalicular laser DCRs should be revised, if necessary, using the external approach.

Meta-Analysis Review
BACKGROUND
Common bile duct stones (CBDS) have a reported recurrence rate of 4%-24% after stone extraction. The most commonly applied stone extraction method is endoscopic cholangiopancreatography (ERCP). We conducted a systematic review and meta-analysis to identify all available risk factors for recurrent CBDS following stone retraction.
RESEARCH DESIGN AND METHODS
A literature search of studies with case-control design was performed to identify potential risk factors for recurrent CBDS. The impact of different risk factors on stone recurrence was analyzed. Pooled odds ratios (ORs) with 95% CIs and heterogeneity were calculated. Identified risk factors were graded as 'strong,' 'moderate,' or 'weak' after quality assessment.
RESULTS
A total of 46 studies discussing stone recurrence following ERCP treatment were included. CBD diameter1.5 cm, sharp CBD angulation, multiple ERCP sessions, postoperative pneumobilia, history of CBD incision, and biliary stent placement were identified as strong risk factors; larger CBD diameter, periampullary diverticulum, mechanical lithotripsy, and history of cholecystectomy were identified as moderate. Other weak risk factors were also listed.
CONCLUSIONS
In this comprehensive study, we identified 14 risk/protective factors for recurrent CBDS following ERCP. Pooled odds ratios were calculated and evaluated the quality of evidence. These findings may shed light on the assessment and management of CBDS.

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.

Obstetrical & Gynecological Survey Jun 2009To review systematically the literature, published in English, on recurrence and healing after treatment of Bartholin duct cysts and abscesses. (Review)
Review
OBJECTIVE
To review systematically the literature, published in English, on recurrence and healing after treatment of Bartholin duct cysts and abscesses.
DATA SOURCES
We searched PubMed, EMBASE, CINAHL, LILACS, Web-of-science, the Cochrane database, and POPLINE from 1982 until May 2008. We searched the internet, hand-searched reference lists, and contacted experts and authors of relevant papers to detect all published and unpublished studies.
METHODS OF STUDY SELECTION
We included any study with at least 10 participants, addressing either frequency of recurrence or healing time after treatment of Bartholin duct cyst or abscess. We followed MOOSE (meta-analysis of observational studies in epidemiology) guidelines. Of 532 articles identified, 24 studies (5 controlled trials, 2 cohort studies, and 17 case series) met all inclusion criteria. Study size ranged between 14 and 200 patients.
TABULATION, INTEGRATION, AND RESULTS
The interventions included: (1) Silver nitrate gland ablation, (2) cyst or abscess fenestration, ablation, or excision using carbon dioxide (CO(2)) laser, (3) marsupialization, (4) needle aspiration with or without alcohol sclerotherapy, (5) fistulization using a Word catheter, Foley catheter, or Jacobi ring, (6) gland excision, and (7) incision and drainage followed by primary suture closure. The reported frequency of recurrence varied from 0% to 38%. There was no recurrence after marsupialization in available studies. Recurrence after other treatments varied, and was most common after aspiration alone. Healing generally occurred in 2 weeks or less.
CONCLUSION
There are multiple treatments for Bartholin duct cysts and abscesses. A review of the literature failed to identify a best treatment approach.
TARGET AUDIENCE
Obstetricians & Gynecologists, Family Physicians
LEARNING OBJECTIVES
After completion of this article, the reader should be able to identify seven different treatments for Bartholin duct cysts or abscesses, contrast treatment choice complications and recurrence risks for the different options for treatment of Bartholin duct cysts or abscesses, and point out the limited quality and quantity of data upon which to choose best practices.
