INTRODUCTION
Gallstone sigmoid ileus is a rare although serious complication of cholelithiasis resulting in large bowel obstruction. The condition accounts for 4% of all gallstone ileus patients. There are no recognized management guidelines currently. Management strategies range from minimally invasive endoscopy and lithotripsy to substantial surgery. We aim to identify trends when managing patients with gallstone sigmoid ileus to help improve outcomes.
METHODS
Literature searches of EMBASE, Medline and by hand were conducted. All English language papers published from 2000 to 2017(Oct) were included. The terms 'gallstone', 'sigmoid', 'colon', 'ileus', 'coleus' and 'large bowel obstruction' were used.
RESULTS
38 papers included, male:female ratio was 8:30. Average age was 81.11 (SD ± 7.59). Average length of preceding symptoms was 5.31days (+/-SD3.16). 20/38 (59%) had diverticulosis. 89% of patients had significant comorbidities documented. 34/38 patients underwent computerized tomography. 31 stones were located within sigmoid colon, 4 at rectosigmoid junction and 2 within descending colon. Average impacted gallstone size was 4.14 cm (2.3-7 cm range). 23/38 (61%) patients' initial management was conservative or with endoscopy ± lithotripsy. Conservative management successfully treated 26% of patients. 28/38 (74%) patients ultimately underwent surgical intervention. 5/38 patients died post-operatively. Patients treated non-operatively had shorter hospital stays (4:12.3days) although not significant (p-value = 0.0056).
CONCLUSIONS
There is no management consensus from the literature. Current evidence highlights endoscopy and lithotripsy as practical firstline strategies. However, surgical intervention should not be delayed if non-operative measures fail or in emergency. Given the complexity of such patients, less invasive timesaving surgery appears practical, avoiding bowel resection and associated complications.

A systematic review and meta-analysis of the efficacy and safety of hysteroscopic electric resection versus vaginal surgery in the treatment of uterine scar defects after cesarean section.
BACKGROUND
Cesarean sections are increasingly likely to be applied; however, uterine scar defects (USD) often remain after delivery. The two existing treatment methods, hysteroscopic electric resection and vaginal surgery, are still controversial in terms of efficacy and safety. So, this paper to compares the effectiveness and safety of hysteroscopic electric resection and vaginal surgery in the treatment of USD after cesarean section.
METHODS
We performed a related literature search from main databases. According to the PICOS principles inclusion criteria were adult female USD patients to evaluate the efficacy of hysteroscopic resection and vaginal surgery for the treatment of USD, outcome data could be extracted to compare the efficacy and safety of the two procedures. Subsequently, according to the titles, abstracts, and full texts of the retrieved articles, studies that did not meet the inclusion criteria were eliminated. The RevMan 5.20 software was used for meta-analysis and Cochrane Risk of Bias 2 (RoB 2.0) was used to assess the risk of bias. The effectiveness and safety of hysteroscopic resection and vaginal surgery in the treatment of USD patients after cesarean section were compared.
RESULTS
Eight articles were finally included, with a total of 191 patients in the hysteroscopic electric resection group and 212 patients in the vaginal surgery group. Compared with hysteroscopic resection and vaginal surgery, there is less intraoperative blood loss [mean difference (MD) is -25.23, P<0.00001], shorter operation time (MD is -29.45, P<0.00001), and shorter hospital stay (MD is -1.87, P<0.00001), but menstrual improvement risk ratio (RR) is 0.71 (P=0.51) and diverticulum recovery RR is 0.60 (P=0.43) there were no significant differences.
DISCUSSION
Hysteroscopic electric resection provides a more satisfactory outcome than vaginal surgery in terms of intraoperative blood loss, operation time, and hospital stay. However, the sample size of the study was not large enough and some studies had high risk of bias, more large-sample multi-center high quality studies are needed for further comprehensive comparative analysis.

Review
Aneurysms and dissections of the right-sided aortic arch are rare and published data are limited to a few case reports and small series. The optimal treatment strategy of this entity and the challenges associated with their management are not yet fully investigated and conclusive. We performed a systematic review of the literature to identify all patients who underwent surgical or endovascular intervention for right aortic arch aneurysms or dissections. The search was limited to the articles published only in English. We focused on presentation and critically assessed different management strategies and outcomes. We identified 74 studies that reported 99 patients undergoing surgical or endovascular intervention for a right aortic arch aneurysm or dissection. The median age was 61 years. The commonest presenting symptoms were chest or back pain and dysphagia. Eighty-eight patients had an aberrant left subclavian artery with only 11 patients having the mirror image variant of a right aortic arch. The commonest pathology was aneurysm arising from a Kommerell's diverticulum occurring in over 50% of the patients. Twenty-eight patients had dissections, 19 of these were Type B and 9 were Type A. Eighty-one patients had elective operations while 18 had emergency procedures. Sixty-seven patients underwent surgical treatment, 20 patients had hybrid surgical and endovascular procedures and 12 had totally endovascular procedure. There were 5 deaths, 4 of which were in patients undergoing emergency surgery and none in the endovascular repair group. Aneurysms and dissections of a right-sided aortic arch are rare. Advances in endovascular treatment and hybrid surgical and endovascular management are making this rare pathology amenable to these approaches and may confer improved outcomes compared with conventional extensive repair techniques.

Review
3D printing in adult cardiac and vascular surgery has been evaluated over the last 10 years, and all of the available literature reports benefits from the use of 3D models. In the present study, we analyzed the current applications of 3D printing for adult cardiovascular disease treated with surgical or catheter-based interventions, including the clinical medical simulation of physiological or pathology conducted with 3D printing in this field. A search of PubMed and MEDLINE databases were supplemented by searching through bibliographies of key articles. Thereafter, data on demographic, clinical scenarios and application, imaging modality, purposes of using with 3D printing, outcomes and follow-up were extracted. A total of 43 articles were deemed eligible and included. 296 patients (mean age: 65.4±14.2 years; male, 58.2%) received 3D printing for cardiac and vascular surgery or conditions [percutaneous left atrial appendage occlusion (LAAO), TAVR, mitral valve disease, aortic valve replacement, coronary artery abnormality, HOCM, aortic aneurysm and aortic dissection, Kommerell's diverticulum, primary cardiac tumor and ventricular aneurysm]. Eight papers reported the utility of 3D printing in the medical simulator and training fields. Most studies were conducted starting in 2014. Twenty-six was case report. The major scenario used with 3D printing technology was LAAO (50.3%) and followed by TAVR (17.6%). CT and echocardiography were two main imaging techniques that were used to generate 3D-printed heart models. All studies showed that 3D-printed models were helpful for preoperative planning, orientation, and medical teaching. The important finding is that 3D printing provides a unique patient-specific method to assess complex anatomy and is helpful for intraoperative orientation, decision-making, creating functional models, and teaching adult cardiac and vascular surgery, including catheter-based heart surgery.

Review
Mitochondrial disorders (MIDs) due to respiratory-chain defects or nonrespiratory chain defects are usually multisystem conditions [mitochondrial multiorgan disorder syndrome (MIMODS)] affecting the central nervous system (CNS), peripheral nervous system, eyes, ears, endocrine organs, heart, kidneys, bone marrow, lungs, arteries, and also the intestinal tract. Frequent gastrointestinal (GI) manifestations of MIDs include poor appetite, gastroesophageal sphincter dysfunction, constipation, dysphagia, vomiting, gastroparesis, GI pseudo-obstruction, diarrhea, or pancreatitis and hepatopathy. Rare GI manifestations of MIDs include dry mouth, paradontosis, tracheoesophageal fistula, stenosis of the duodeno-jejunal junction, atresia or imperforate anus, liver cysts, pancreas lipomatosis, pancreatic cysts, congenital stenosis or obstruction of the GI tract, recurrent bowel perforations with intra-abdominal abscesses, postprandial abdominal pain, diverticulosis, or pneumatosis coli. Diagnosing GI involvement in MIDs is not at variance from diagnosing GI disorders due to other causes. Treatment of mitochondrial GI disease includes noninvasive or invasive measures. Therapy is usually symptomatic. Only for myo-neuro-gastro-intestinal encephalopathy is a causal therapy with autologous stem-cell transplantation available. It is concluded that GI manifestations of MIDs are more widespread than so far anticipated and that they must be recognized as early as possible to initiate appropriate diagnostic work-up and avoid any mitochondrion-toxic treatment.

Review
INTRODUCTION
Associated with the Western diet and life style,diverticular disease is affecting more and more developing countries worldwide. Recent studies show an increase in incidence of the disease at young age, that raises the risk of complications, along with major consequences for the patient but also for the healthcare system.
METHOD
Systematic review of the literature with US National Library of Medicine and National Institutes of Health International PubMed Medline, using abstracts and articles available in PubMed Medline, Cochrane databases searching for ("Diverticulosis, Colonic epidemiology" [MeSH] OR"Diverticulosis, Colonic etiology" [MeSH] OR "Diverticulosis,Colonic genetics" [MeSH] OR "Diverticulosis, Colonic history" [MeSH]).
RESULTS
Even from the rise of diverticular disease as a public healthcare problem, at the end of the previous century, it was associated with a diet rich in refined sugars, lacking vegetable fibres. The higher incidence in countries like U.S.A., Canada, United Kingdom and the northern states compared with its rare occurrence in the sub-Saharan African continent, strengthen the anterior assumptions. In regions like Asia, the disease pattern is characterized by are latively low incidence of colonic diverticular disease, with distribution of diverticula mainly on the right colon. The different incidence by sex and age show the possible existence of hormonal protective factors. Studies from countries with a rich ethnic diversity, bring into question the probable genetic predisposition to diverticular disease, fact backed-up by the few studies on twins and 1st degree relatives available in the literature.
DISCUSSION
The rising incidence of colonic diverticular disease in Romania makes our country adhere the epidemiologic model existing in countries with a close socio-economic status.Although with a lower incidence than countries that have adopted a Western diet, Romania is likely to encounter a public health problem, if certain measures to identify and minimise the population exposure to risk factors are not taken.

Meta-Analysis
BACKGROUND/OBJECTIVES
The possible relationship between smoking and risk of colonic diverticulosis has been suggested by recent epidemiological studies, although the results were inconsistent. This meta-analysis was conducted to summarize all available data.
METHODS
A comprehensive literature review was conducted using the MEDLINE and EMBASE databases through May 2017 to identify all studies that compared the risk of colonic diverticulosis among current and former smokers versus nonsmokers. Effect estimates from each study were extracted and combined together using the random-effect, generic inverse variance method of DerSimonian and Laird.
RESULTS
Of 465 potentially eligible articles, three prospective cohort studies with 130,520 participants met the eligibility criteria and were included in the meta-analysis. The risk of colonic diverticulosis in current smokers was significantly higher than nonsmokers with the pooled risks ratio of 1.46 (95% confidence interval [CI], 1.13-1.89). However, the risk of colonic diverticulosis in former smokers was not significantly higher than nonsmokers with the pooled risk ratio of 1.13 (95% CI, 0.88-1.44).
CONCLUSIONS
A significantly increased risk of colonic diverticulosis among current smokers is demonstrated in this study.

Review
Zenker's diverticulum treatment options range from endoscopic rigid or flexible procedures to surgery. There are limited studies available comparing these techniques. Frequently, the choice of treatment depends on the physician's preference or experience, as well as the institution's resources and capacity. Therefore, this study aims to define the best approach based on the highest efficacy and the lowest severe adverse events. In accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a comprehensive search was performed. Only comparative studies were included, analyzing flexible endoscopy versus rigid endoscopy or surgery. The outcomes analyzed were clinical and technical success, severe adverse events, length of stay, and duration of the procedure. Analysis was performed using Review Manager 5.4.1 (RevMan 5.4, The Cochrane Collaboration, The Nordic Cochrane Centre, Copenhagen, Denmark). Eight retrospective cohort studies met the inclusion criteria. A total of 1281 patients were identified, 492 underwent flexible endoscopy, 453 underwent rigid endoscopy, and 336 underwent surgery. There was no difference in clinical success [risk difference (RD), 0.07 (95% CI -0.05 to 0.19%); P = 0.26], technical success [RD, 0.07 (95% CI -0.03 to 0.16); P = 0.18], severe adverse events [RD, -0.03 (95% CI -0.13 to 0.07; P = 0.052), perforation [RD, 0.07 (95% CI -0.04 to 0.19); P = 0.22] or procedure time [mean difference (MD), - 10.03 (95% CI -26.93 to 6.88); P = 0.24). There was lower length of stay with flexible endoscopy compared to the other approaches [MD, -1.98 (95% CI -3.56 to -0.40); P = 0.001]. Based on the current evidence, the three main techniques are effective for the treatment of Zenker's diverticulum. Although there was no significant difference in the safety of each technique in this meta-analysis, this result should be interpreted cautiously due to the limited data and the risk of vies between the techniques, considering that the results tend to favor flexible endoscopy, mainly explained by the newer and safer devices. Length of stay is lower with flexible endoscopy versus the other techniques, which can be beneficial considering the geriatric populations where Zenker's diverticulum mainly occurs.

Meta-Analysis Review
Diverticular disease (DD) is the most frequent condition in the Western world that affects the colon. Although chronic mild inflammatory processes have recently been proposed as a central factor in DD, limited information is currently available regarding the role of inflammatory cytokines, such as tumor necrosis factor-alpha (TNF-α). Therefore, we conducted a systematic review and meta-analysis aiming to assess the mucosal TNF-α levels in DD. We conducted a systematic literature search using PubMed, Embase, and Scopus to identify observational studies assessing the TNF-α levels in DD. Full-text articles that satisfied our inclusion and exclusion criteria were included, and a quality assessment was performed using the Newcastle-Ottawa Scale (NOS). The principal summary outcome was the mean difference (MD). The results were reported as MD (95% confidence interval (CI)). A total of 12 articles involving 883 subjects were included in the qualitative synthesis, out of which 6 studies were included in our quantitative synthesis. We did not observe statistical significance related to the mucosal TNF-α levels in symptomatic uncomplicated diverticular disease (SUDD) vs. the controls (0.517 (95% CI -1.148-2.182)), and symptomatic vs. asymptomatic DD patients (0.657 (95% CI -0.883-2.196)). However, the TNF-α levels were found to be significantly increased in DD compared to irritable bowel disease (IBS) patients (27.368 (95% CI 23.744-30.992)), and segmental colitis associated with diverticulosis (SCAD) vs. IBS patients (25.303 (95% CI 19.823-30.784)). Between SUDD and the controls, as well as symptomatic and asymptomatic DD, there were no significant differences in the mucosal TNF-α levels. However, the TNF-α levels were considerably higher in DD and SCAD patients than IBS patients. Our findings suggest that TNF-α may play a key role in the pathogenesis of DD in specific subgroups and could potentially be a target for future therapies.

Comparative Study Meta-Analysis Review
PURPOSE
This meta-analysis was conducted to compare postoperative outcomes between transverse island flap (TVIF) onlay and tubularized incised-plate (TIP) urethroplasties for primary proximal hypospadias.
MATERIALS AND METHODS
A comprehensive literature search updated to 21st May 2014 was carried out for relevant studies. After literature identification and data extraction, odds ratio (OR) with 95% confidential interval (CI) was calculated to compare postoperative complication rate between TVIF onlay and TIP. Meta-regression and subgroup analyses were applied to find potential affective factors.
RESULTS
A total of 6 studies including 309 patients receiving TVIF onlay and 262 individuals subjected to TIP met inclusion criteria. The synthetic data suggested that TVIF onlay and TIP were comparable in terms of total complication rate (OR 0.85, 95% CI 0.56-1.30, p = 0.461), fistula (OR 0.68, 95% CI 0.38-1.21, p = 0.194), recurrent curvature (OR 1.16, 95% CI 0.43-3.12, p = 0.766), dehiscence (OR 0.95, 95% CI 0.33-2.74, p = 0.920), diverticulum (OR 1.90, 95% CI 0.53-6.78, p = 0.321), meatal stenosis (OR 0.74, 95% CI 0.20-2.77, p = 0.651) and urethral stricture (OR 1.49, 95% CI 0.41-5.50, p = 0.545), without significant heterogeneity for each comparison group. Meta-regression and subgroup analyses revealed no significant findings. One-way sensitivity analysis indicated that the results were stable. No publication bias was detected using both funnel plot and Egger's test. Also, there were no obvious differences observed in cosmetic and functional outcomes.
CONCLUSIONS
This meta-analysis suggests that TVIF onlay and TIP urethroplasties are clinically equivalent. Given the inherent limitations of included studies, this conclusion should be interpreted with caution and wait to be confirmed by more well-designed randomized controlled trials with high quality in the future.
