A Systematic Review and Meta-Analysis of the Management of Gallstone Cholecystitis and Common Biliary Duct Stones to Reduce the Incidence of Complications in Elderly Patients.
As the age increases particularly above the age of 50 years, there is a significantly higher risk of developing gallstone-related complications especially cholecystitis and common bile duct stones with its associated consequences. Complications that arise after surgical operations for cholecystitis have been reported to have negative impacts on senior patients. These effects include a higher rate of complications, a longer hospital stay, higher expenditures, and decreased patient satisfaction. Therefore, finding the most effective treatment for cholecystitis in older patients is still a challenge. The aim of the study was carried out in order to identify many approaches that can be taken in the treatment of cholecystitis and stones in the common bile duct in older patients. A search was conducted through Medline (PubMed), EMBASE, ProQuest, and Cochrane using relevant Medical Subject Heading (MeSH) terms and keywords (elderly, age over 50, cholecystitis, bile duct stones, cholecystectomy, ERCP, surgical, conservative management, and open). The searches were limited to studies on elderly individuals over 50 who had cholecystectomy and endoscopic retrograde cholangiopancreatography between January 2000 and December 2022. The meta-analysis used the Mantel-Haenszel odds ratio (MHOR) and 95% confidence interval (CI). Aries Systems Corporation's Editorial Manager® (Aries Systems Corporation, North Andover, USA) and ProduXion Manager® (Aries Systems Corporation, North Andover, USA) facilitated the study. Out of 102 citations, 39 studies were selected for further study. After that, 18 studies were eliminated, leaving 21 for meta-analysis. The study found a protective risk of cholecystitis in cholecystectomy patients (MHOR = 0.16; 95%, CI = 0.10 to 0.25; p 0.001). Developing cholecystitis was substantially lower in early cholecystectomy patients (MHOR = 0.16; 95%, CI = 0.10 to 0.25; p 0.001). There was no significant difference in cholecystitis risk between open and laparoscopic surgery (MHOR = 0.65; 95%, CI = 0.41 to 1.04; p 0.07). Cholecystectomy performed at an earlier stage protects elderly patients from developing recurrent cholecystitis. In contrast to late cholecystitis, in which the patient would experience several attacks of cholecystitis, early cholecystectomy protects against the recurrence of the condition.

Meta-Analysis
BACKGROUND AND AIMS
The use of statins has been shown to be associated with a decreased risk of cholangiocarcinoma (CCA) in many studies although the results have been inconsistent. We conducted this systematic review and meta-analysis to further investigate this possible association by identifying all relevant studies and combining their results together.
METHODS
A comprehensive literature review was conducted utilizing the MEDLINE and EMBASE databases through March 2020 to identify all studies that compared the risk of CCA among individuals who use statins with individuals who do not use statins. Effect estimates from each study were extracted and combined using the random-effect, generic inverse variance method of DerSimonian and Laird.
RESULTS
A total of seven studies with 6,251,187 participants fulfilled the eligibility criteria and were included in this meta-analysis. The pooled analysis found a significantly decreased risk of CCA among individuals who use statins compared with individuals who do not use statins with the pooled odds ratio of 0.68 (95% CI: 0.52-0.89; I 2 96%).
CONCLUSIONS
The current systematic review and meta-analysis found a significant association between the use of statins and a decreased risk of CCA.

INTRODUCTION
Periductal mastitis (PDM) is a complex benign breast disease with a prolonged course and a high risk of recurrence after treatment. There are many available treatments for PDM, but none is widely accepted. This study aims to evaluate the various treatment failure rates (TFR) of different invasive treatment measures by looking at recurrence and persistence after treatment. In this way, it sets out to inform better clinical decisions in the treatment of PDM.
METHODS
We searched PubMed, Embase, and Cochrane Library databases for eligible studies about different treatment regimens provided to PDM patients that had been published before October 1, 2019. We included original studies written in English that reported the recurrence and/or persistence rates of each therapy. Outcomes were presented as pooled TFR and 95% CI for the TFR.
RESULTS
We included 27 eligible studies involving 1,066 patients in this study. We summarized 4 groups and 10 subgroups of PDM treatments, according to the published studies. Patients treated minimally invasively (group 1) were subdivided into 3 subgroups and pooled TFR were calculated as follows: incision and drainage ( = 73; TFR = 75.6%; 95% CI 27.3-100%), incision alone ( = 74; TFR = 20.1%; 95% CI 0-59.9%), and breast duct irrigation ( = 123; TFR = 19.4%; 95% CI 0-65.0%). Patients treated with a minor excision (excision of the infected tissue and related duct; group 2) were divided into 4 subgroups and pooled TFR were calculated as follows: wound packing alone ( = 127; TFR = 2.1%; 95% CI 0-5.2%), primary closure alone ( = 66; TFR = 37.1%; 95% CI 9.5-64.8%), primary closure under antibiotic treatment cover ( = 55; TFR = 4.8%; 95% CI 0-11.4%), and additional nipple part removal ( = 232; TFR = 9.6%; 95% CI 5.8-13.4%). Patients treated with a major excision (excision of the infected tissue and the major duct; group 3) included the following 2 subgroups: patients treated with a circumareolar incision ( = 142; TFR = 7.5%; 95% CI 0.4-14.7%) and patients treated with a radial incision of the breast ( = 78; TFR = 0.6%; 95% CI 0-3.6%). Group 4 contained patients receiving different major plastic surgeries. The pooled TFR of this group ( = 86) was 3.4% (95% CI 0-7.5%).
CONCLUSION
Breast duct irrigation, which is the most minimally invasive of all of the treatment options, seemed to yield good outcomes and may be the first-line treatment for PDM patients. Minor excision methods, except for primary closure alone, might be enough for most PDM patients. Major excision, especially with radial incision, was a highly effective salvage therapy. The major plastic surgery technique was also acceptable as an alternative treatment for patients with large lesions and concerns about breast appearance. Incision and drainage and minor excision with primary closure alone should be avoided for PDM patients. Further research is still needed to better understand the etiology and pathogenesis of PDM and explore more effective treatments for this disease.

Comparative Study Meta-Analysis Review
BACKGROUND
Postoperative pancreatic fistula (POPF) is one of the most common complications after pancreaticoduodenectomy (PD). The ideal choice of pancreaticojejunostomy (PJ) anastomosis remains a matter of debate.
METHODS
A meta-analysis of randomized controlled trials (RCTs) comparing duct-to-mucosa with invagination PJ following PD was performed. Pooled odds ratio (OR) with 95 % confidence intervals (CI) were calculated using fixed-effects or random-effects models.
RESULTS
In total, five RCTs involving 654 patients were included. Meta-analysis revealed no significant difference in POPF rate between the duct-to-mucosa and invagination PJ techniques (OR = 1.23, 95 % CI = 0.78-1.93; P = 0.38). Two of five trials applied the POPF definition proposed by the International Study Group of Pancreatic Surgery (ISGPS). Using this definition, the incidence of clinically relevant POPF was lower in patients undergoing invagination PJ than in those undergoing duct-to-mucosa PJ (OR = 2.94, 95 % CI = 1.31-6.60; P = 0.009). There was no significant difference in terms of delayed gastric emptying, intra-abdominal collection, overall morbidity and mortality, reoperation rate, and length of hospital stay between the two groups.
CONCLUSION
Invagination PJ is not superior to duct-to-mucosa PJ in terms of POPF and other complications but appears to reduce clinically relevant POPF. Further well-designed RCTs that use ISGPS definition are still required before strong evidence-based recommendations can be formulated.

Review
Physiological properties and function of the lymphatic system is still somewhat of a mystery. We report the current knowledge about human lymphatic vessel contractility and capability of adaptation. A literature search in PubMed identified studies published January 2000-September 2022. Inclusion criteria were studies investigating parameters related to contraction frequency, fluid velocity, and lymphatic pressure in vivo and ex vivo in human lymphatic vessels. The search returned 2885 papers of which 28 met the inclusion criteria. In vivo vessels revealed baseline contraction frequencies between 0.2 ± 0.2 and 1.8 ± 0.1 min , velocities between 0.008 ± 0.002 and 2.3 ± 0.3 cm/s, and pressures between 4.5 (range 0.5-9.2) and 60.3 ± 2.8 mm Hg. Gravitational forces, hyperthermia, and treatment with nifedipine caused increases in contraction frequency. Ex vivo lymphatic vessels displayed contraction frequencies between 1.2 ± 0.1 and 5.5 ± 1.2 min . Exposure to agents affecting cation and anion channels, adrenoceptors, HCN channels, and changes in diameter-tension properties all resulted in changes in functional parameters as known from the blood vascular system. We find that the lymphatic system is dynamic and adaptable. Different investigative methods yields alternating results. Systematic approaches, consensus on investigative methods, and larger studies are needed to fully understand lymphatic transport and apply this in a clinical context.

Review
AIM
To review applications of confocal laser endomicroscopy (CLE) in pancreatobiliary lesions and studies that assessed training and interpretation of images.
METHODS
A computerized literature search was performed using OVID MEDLINE, EMBASE, Cochrane library, and the ISI Web of Knowledge from 1980 to October 2014. We also searched abstracts from major meetings that included the Digestive Disease Week, Canadian Digestive Disease Week and the United European Gastroenterology Week using a combination of controlled vocabulary and text words related to pCLE, confocal, endomicroscopy, probe-based confocal laser endomicroscopy, and bile duct to identify reports of trials. In addition, recursive searches and cross-referencing was performed, and manual searches of articles identified after the initial search was also completed. We included fully published articles and those in abstract form. Given the relatively recent introduction of CLE we included randomized trials and cohort studies.
RESULTS
In the evaluation of indeterminate pancreatobiliary strictures CLE with ERCP compared to ERCP alone can increase the detection of cancerous strictures with a sensitivity of (98% vs 45%) and has a negative predictive value (97% vs 69%), but decreased the specificity (67% vs 100%) and the positive predictive value (71% vs 100%) when compared to index pathology. Modifications in the classification systems in indeterminate biliary strictures have increased the specificity of pCLE from 67% to 73%. In pancreatic cystic lesions there is a need to develop similar systems to interpret and characterize lesions based on CLE images obtained. The presence of superficial vascular network predicts serous cystadenomas accurately. Also training in acquiring and interpretation of images is feasible in those without any prior knowledge in CLE in a relatively simple manner and computer-aided diagnosis software is a promising innovation.
CONCLUSION
The role of pCLE in the evaluation of pancreatobiliary disorders might be better suited for those with an intermediate and low probability.

Meta-Analysis Review
Objective Although thyroglossal duct cysts (TGDCs) are relatively common, malignancies within these lesions are infrequent. As a result, there are no large-scale series describing clinical characteristics. Our objectives were to perform a systematic review of the literature evaluating patient demographics, pathology, management, and prognosis of these patients. Data Sources PubMed, Embase, Cochrane reviews, and Google Scholar were searched for relevant articles. Articles meeting inclusion criteria were reviewed for data detailing epidemiology, treatment, and outcomes. Review Methods Inclusion criteria included English-language articles with original reports on human subjects. Two investigators independently reviewed all articles for the data collected, including epidemiology, treatment, and outcomes. Results Ninety-eight articles comprising 164 patients were included in the final analysis. The mean age at presentation was 39.5 years (9-83 years); 68.3% of patients were female. In total, 73.3% of cases were found on final pathologic analysis. The most common pathology was papillary cancer (92.1%). Of the patients, 98.9% underwent a Sistrunk procedure and 61.0% underwent total thyroidectomy. There was a 4.3% recurrence rate with a mean time to recurrence of 42.1 months from initial treatment. One patient died of TGDC carcinoma, while all other patients were disease free at the time of last follow-up (mean follow-up was 46.1 months). Conclusion TGDC carcinoma is typically diagnosed on final pathology. While management encompasses a Sistrunk procedure, further consideration should be given to thyroidectomy among patients ≥45 years of age and individuals with aggressive disease. TGDC carcinoma harbors an exceedingly low rate of mortality.

Review
The prevalence of pancreatic cystic echinococcosis (PCE) in the world is low ranging between 0.2% and 0.6%. The diagnosis of PCE is easy when it is associated to other location such as liver, it became difficult when PCE was isolated simulating other diagnosis such as pseudocyst, a choledochal cyst, serous or mucinous cystadenoma and cystadenocarcinoma. This systematic review aimed to provide evidence-based answer to the following questions: (I) what are the efficient tools to affirm the diagnosis of isolated PCE and (II) what are the best therapeutic strategy for the PCE? An electronic search was performed by two authors (W Dougaz, I Bouasker). Medline, Scopus, Embase, Web of Science, Google Scholar and Cochrane collaboration were consulted. The keywords used were "cyst", "echinococcosis", "hydatid cyst" and "pancreas". All abstracts were analyzed followed by extraction of the full text by the same two authors (W Dougaz, I Bouasker), all divergences were resolved by discussion with C Dziri. Recommendations were based on Oxford's classification: (I) what are the efficient tools to affirm the diagnosis of PCE? -ultrasound remains the cornerstone of diagnosis. Magnetic resonance imaging (MRI) reproduces the ultrasound defined features of CE better than computed tomography (CT). MRI with heavily T2-weighted series is preferable to CT. Pancreatic duct MRI should be promising to identify a fistula between PCE and pancreatic duct (level of evidence 3-recommendation B); (II) what are the best therapeutic strategy for the PCE? -surgery is the main treatment of PCE. Open approach is validated. The decision depends of the location of PCE: head body and/or tail of the pancreas (level of evidence 5-recommendation D): for the head of the pancreas, the tendency is toward conservative surgery. For body and/or tail of the pancreas, the tendency is toward radical surgery. Medical treatment (albendazole) should be prescribed 1 week before surgery and 2 months during postoperative period (level II evidence and grade C recommendation).

Meta-Analysis Review
A systematic review and meta-analysis were conducted to evaluate the success and complications of endoscopic laser dacryocystorhinostomy (ELDCR) vs. external dacryocystorhinostomy (ExDCR) in primarily acquired nasal duct obstruction. The search of PubMed, Embase, and Cochrane Central Register of Controlled Trials databases revealed 109 studies on ELDCR and ExDCR. Eleven studies were found to be suitable for review. The primary objective was to compare the success rate between ELDCR and ExDCR. The secondary objectives were to analyze the surgical time, overall complications, bleeding, infection, intranasal synechia, and granulation tissue. Pooled analysis of all studies revealed that ELDCR had a significantly lesser success rate compared to ExDCR (80.3% vs. 91.6%; odds ratio [OR] 0.41; 95% confidence interval [CI] [0.27, 0.62]; P < 00001; I = 13%). However, there were no difference in the overall complication rate (12.0% vs. 13.0%; OR 1.04; 95% CI [0.17, 6.33]; P = 0.97, I = 80%) and intranasal synechiae (9.5% vs. 4.3%; OR 2.22 [1.04, 4.72]; P = 0.04; I = 10%). The ExDCR group had significantly increased risks of bleeding (1.9% vs. 13.0%; OR 0.20; 95% CI [0.09, 0.47]; P = 0.0002; I = 0%) and infection (0.3% vs. 4.6%; OR 0.09; 95%CI [0.02, 0.51]; P = 0.006; I = 0%). Nevertheless, ELDCR needed a shorter surgical time compared to ExDCR (mean difference [MD] -28.35, 95% CI [-35.45, -21.26], P < 0.00001, I = 78%). Although ELDCR is associated with lesser bleeding, lesser infection, and shorter surgical duration, the success rate of ExDCR is higher.

Review
The cisterna chyli is a lymphatic structure found at the caudal end of the thoracic duct that receives lymph draining from the abdominal and pelvic viscera and lower limbs. In addition to being an important landmark in retroperitoneal surgery, it is the key gateway for interventional radiology procedures targeting the thoracic duct. A detailed understanding of its anatomy is required to facilitate more accurate intervention, but an exhaustive summary is lacking. A systematic review was conducted, and 49 published human studies met the inclusion criteria. Studies included both healthy volunteers and patients and were not restricted by language or date. The detectability of the cisterna chyli is highly variable, ranging from 1.7 to 98%, depending on the study method and criteria used. Its anatomy is variable in terms of location (vertebral level of T10 to L3), size (ranging 2-32 mm in maximum diameter and 13-80 mm in maximum length), morphology, and tributaries. The size of the cisterna chyli increases in some disease states, though its utility as a marker of disease is uncertain. The anatomy of the cisterna chyli is highly variable, and it appears to increase in size in some disease states. The lack of well-defined criteria for the structure and the wide variation in reported detection rates prevent accurate estimation of its natural prevalence in humans.
