Review
: To present a review of the current literature regarding the presentation, diagnosis, and treatment of female urethral diverticula (UD). : A systematic search of the PubMed database was performed to identify studies evaluating female UD. Article titles, abstracts and full-text manuscripts were screened to identify relevant studies, which then underwent data extraction and analysis. : In all, 50 studies evaluating the presentation, diagnosis and treatment of female UD were deemed relevant for inclusion. Almost all studies were retrospective single-arm case series. Female UD are outpouchings of the urethral lumen into the surrounding connective tissue. The presentation of female UD is diverse and can range from incidental findings to lower urinary tract symptoms, frequent urinary tract infections, dyspareunia, urinary incontinence (UI), or malignancy. Repair of UD begins with an accurate assessment and diagnosis, which should include adequate radiographic imaging, usually including magnetic resonance imaging. Once the diagnosis is confirmed, the usual treatment is surgical excision and reconstruction, most often through a transvaginal approach. The principles of transvaginal urethral diverticulectomy include: removal of the entire urethral diverticulum wall, watertight closure of the urethra, multi-layered and non-overlapping closure of surrounding tissue with absorbable suture, and preservation or creation of continence. Results of surgical repair are usually excellent, although long-term recurrence of these lesions may occur. Complications of urethral diverticulectomy include urethrovaginal fistula, UI, and rarely urethral stricture. : Whilst urethral diverticulectomy excision and reconstruction is a challenging procedure, it is ultimately satisfying for the patient and the surgeon when relief of bothersome symptoms is achieved. Adherence to principles of reconstructive surgery is important to ensure a satisfactory result. PRISMA: Preferred Reporting Items for Systematic Reviews and Meta-Analyses; UD: urethral diverticulum/diverticula; UI: urinary incontinence; US: ultrasonography; VCUG: voiding cystourethrogram.

Meta-Analysis
BACKGROUND/AIMS
Diverticulosis and colorectal neoplasia share epidemiological trends and risk factors which are common in Western countries and incidences increase with age. However, the data on an association between diverticulosis and colorectal neoplasia are conflicting. Thus, we performed a meta-analysis to evaluate whether diverticulosis is associated with colorectal neoplasia.
METHODS
A systematic literature search of PubMed, EMBASE, Cochrane Library, Web of Science, and SCOPUS was conducted to identify studies that investigated the association between diverticulosis and advanced colorectal neoplasia (advanced adenoma, colorectal cancer), adenomas, or polyps. The demographic characteristics of patients, including age, gender, indication for colonoscopy, confounding factors, and outcomes of colorectal neoplasia were assessed.
RESULTS
We identified 29 cross-sectional studies (N = 450,953) that investigated the association between diverticulosis and colorectal neoplasia. The meta-analysis found that diverticulosis was not associated with advanced colorectal neoplasia (odds ratio [OR] 0.98, 95% confidence interval [CI] 0.63-1.50). Although there was a positive correlation between diverticulosis and adenomas (OR 1.47, 95% CI 1.18-1.84) and diverticulosis and polyps (OR 1.95, 95% CI 1.15-3.31), diverticulosis did not increase the risk of adenomas (OR 1.34, 95% CI 0.87-2.06) in patients who underwent screening colonoscopy. Moreover, all the increased risk of colorectal neoplasia in patients with diverticulosis was observed in published studies only, and not in unpublished ones.
CONCLUSIONS
This meta-analysis demonstrated that diverticulosis is not associated with an increased risk of advanced colorectal neoplasia. Although diverticulosis was associated with a higher risk of polyps and adenomas, the risk was not increased in screening populations. Moreover, the increased risk of colorectal neoplasia in patients with diverticulosis was observed only in published studies and not in unpublished ones.

Raoultella planticola (R. planticola) is a Gram-negative, aerobic, rod bacteria found in water and soil that has been on rare occasions associated with clinical infections. However, in recent years, there has been both an increase in the frequency and severity of R. planticola infections. We present the first case of Meckel's diverticulum perforation and peritonitis in a child associated with R. planticola infection and a systematic review of the paediatric literature. At present, in the paediatric population, R. planticola presents good susceptibility to a variety of antibiotics with the exception of ampicillin.

BACKGROUND
Diverticular disease treatment is limited to fibres, antibiotics, and surgery. There is conflicting evidence on mesalazine benefits and harms.
AIM
We systematically reviewed current evidence on benefits and harms of mesalazine versus all other treatments in people with diverticular disease.
METHODS
We searched MEDLINE, EMBASE, CENTRAL, ClinicalTrials.gov for studies published to July 2018. We estimated risk ratios (RR) for dichotomous outcomes (disease remission/recurrence, acute diverticulitis in symptomatic uncomplicated diverticular disease, need for surgery/hospitalization, all-cause/disease-related mortality, adverse events), mean differences (MD) or standardized MD (SMD) for continuous outcomes (quality of life, symptoms score, time to recurrence/remission), and their 95% confidence intervals (CI) using random-effects models. We quantified heterogeneity by Chi and I tests. We performed subgroup analyses by disease subtype, comparator, follow-up duration, mesalazine dose, and mode of administration.
RESULTS
We identified 13 randomized trials (n=3028 participants). There was a higher likelihood of disease remission with mesalazine than controls in acute uncomplicated diverticulitis (1 trial, 81 participants, RR=2.67, 95%CI=1.05-6.79), but not in symptomatic uncomplicated diverticular disease (1 trial, 123 participants, RR=1.04, 95%CI=0.81-1.34). There was a lower likelihood of disease recurrence with mesalazine than controls in symptomatic uncomplicated diverticular disease (2 trials, 216 participants, RR=0.52, 95%CI=0.28-0.97), but not in acute uncomplicated diverticulitis (7 trials, 2196 participants, RR=0.90, 95%CI=0.61-1.33). There was no difference in the likelihood of developing acute diverticulitis in symptomatic uncomplicated diverticular disease between the two groups (3 trials, 484 participants, RR=0.26, 95%CI=0.06-1.20). There was a higher global symptoms score reduction with mesalazine than controls in symptomatic uncomplicated diverticular disease (2 trials, 326 participants, SMD=-1.01, 95%CI=-1.51,-0.52) and acute uncomplicated diverticulitis (2 trials, 153 participants, SMD=-0.56, 95%CI=-0.88,-0.24).
CONCLUSIONS
Mesalazine may reduce recurrences in symptomatic uncomplicated diverticular disease. There is uncertainty on the effect of mesalazine in achieving diverticular disease remission. Mesalazine may not prevent acute diverticulitis in symptomatic uncomplicated diverticular disease.

Meta-Analysis
Mesalazine to treat symptomatic uncomplicated diverticular disease and to prevent acute diverticulitis occurrence. A systematic review with meta-analysis of randomized, placebo-controlled trials.
BACKGROUND AND AIMS
Symptomatic Uncomplicated Diverticular disease (SUDD) affects about 25% of patients harboring colonic diverticula. We assessed the effectiveness of mesalazine in improving symptoms (namely abdominal pain, primary outcome) and in preventing diverticulitis occurrence (secondary outcome) in patients with SUDD.
METHODS
Pertinent studies were selected from the Medline and the Cochrane Central Register of Controlled Trials. Only randomized clinical trials (RCTs) (irrespective of language, blinding, or publication status), which compared mesalazine, irrespective of the dosage assumption, with placebo in SUDD were evaluated.
RESULTS
Four RCTs enrolled 379 patients, 197 treated with mesalazine and 182 with placebo. Two studies provided data on symptom relief according to definition: it was achieved in 97/121 (80%) patients in the mesalazine group and in 81/129 (62.7%) patients in the placebo group (OR 0.43; 95% CI 0.24-0.75; p=0.003 in favour of the mesalazine group). Two studies provided information regarding occurrence of diverticulitis during follow-up. It occurred in 23/119 (19.3%) patients in the mesalazine group and in 34/102 (33.3%) patients in the placebo group (OR 0.35; 95% CI 0.17-0.70; p=0.003 in favour of the mesalazine group).
CONCLUSIONS
Treatment with mesalazine seems to be effective in achieving symptom relief and in the primary prevention of diverticulitis in patients with SUDD.

Review
BACKGROUND
The contemporary demographics and prevalence of Meckel's diverticulum, clinical presentation and management is not well described. Thus, this article aims to review the recent literature concerning Meckel's diverticulum.
METHODS
A systematic PubMed/Medline database search using the terms "Meckel" and "Meckel's" combined with "diverticulum." English language articles published from January 1, 2000 to July 31, 2017 were considered. Studies reporting on the epidemiology of Meckel's diverticulum were included.
RESULTS
Of 857 articles meeting the initial search criteria, 92 articles were selected. Only 4 studies were prospective. The prevalence is reported between 0.3% and 2.9% in the general population. Meckels' diverticulum is located 7 to 200 cm proximal to the ileocecal valve (mean 52.4 cm), it is 0.4 to 11.0 cm long (mean 3.05 cm), 0.3 to 7.0 cm in diameter (mean 1.58 cm), and presents with symptoms in 4% to 9% of patients. The male-to-female (M:F 1.5-4:1) gender distribution is reported up to 4 times more frequent in men. Symptomatic patients are usually young. Of the pediatric symptomatic patients, 46.7% have obstruction, 25.3% have hemorrhage, and 19.5% have inflammation as presenting symptom. Corresponding values for adults are 35.6%, 27.3%, and 29.4%. Ectopic gastric tissue is present in 24.2% to 71.0% of symptomatic Meckel's diverticulum, is associated with hemorrhage and is the most common form of ectopic tissue, followed by ectopic pancreatic tissue present in 0% to 12.0%.
CONCLUSION
The epidemiological patterns and clinical presentation appears stable in the 21st century. A symptomatic Meckel's diverticulum is managed by resection. The issue of prophylactic in incidental Meckel's diverticulum resection remains controversial.

BACKGROUND
Meckel's diverticulum is present in about 2% of the population. The literature reports 3.2% incidence of tumors within Meckel's diverticulum; the tumors are predominantly benign.
OBJECTIVE AND METHODS
The purpose of this study was to evaluate malignant tumors in Meckel's diverticulum through systematic review of the literature and review of electronic medical records including pathology reports over 14 years at the Mayo Clinic, Rochester, USA.
RESULTS
A literature review over the last 10 years identified 37 citations with 402 patients (median age: 58 years; 68.9% males). The predominant malignancy reported was neuroendocrine tumor 84.6%, followed by gastrointestinal stromal tumor 8.2%, and adenocarcinoma 6%. At the time of diagnosis, 29.5% of patients had metastases. In the Mayo Clinic electronic medical records review, there were 19 patients (5.1% of them surgically removed Meckel's diverticulum) who had a malignancy associated with Meckel's diverticulum: 63.2% neuroendocrine tumor, 10.5% gastrointestinal stromal tumor, 5.3% adenocarcinoma, 5.3% pancreatic epithelial neoplasia, and 15.8% metastases from secondary location. Median size of the malignancy was 7 mm, and 17/19 malignancies were coincidental findings. Most neuroendocrine tumors infiltrated the submucosa, while gastrointestinal stromal tumor and adenocarcinoma invaded the serosa. At the time of diagnosis, 33.3% of patients had metastases.
CONCLUSION
About 5% of Meckel's diverticulums resected were associated with malignant tumors, most commonly neuroendocrine tumor, and a significant portion of Meckel's diverticulum malignancy was metastatic at the time of discovery.

Meta-Analysis Review
There have been conflicting reports on the association of alcohol use and diverticular disease. We aimed to determine the odds of developing diverticular disease and diverticular bleeding in patients who consumed alcohol on a regular basis compared with those who did not. MEDLINE and PUBMED were searched up until February 2017 on observational trials, which investigated the effect of alcohol use on two outcomes of diverticular disease: diverticulosis and diverticular bleeding. Quantitative estimates (odds ratios [OR] and confidence intervals [CI]) from included studies were pooled by using a random-effects model. Heterogeneity across studies was assessed by the I statistic. In 6 studies including 53,644 subjects and 6 studies including 3,404 subjects, alcohol consumption on a regular basis was not associated with either diverticulosis (OR=1.99; 95% CI 0.99-4.03, I=99%) or diverticular bleeding (OR=1.39; 95% CI 0.84-2.32, I=45%) compared to subjects who did not consume alcohol on a regular basis, respectively. Increased odds of diverticulosis or diverticular bleeding among individuals who consume alcohol on a regular basis were not observed in these meta-analyses.

Meta-Analysis Review
AIM
This systematic review and meta-analysis aimed to clarify whether tobacco smoking is associated with an increased risk of diverticular disease.
METHOD
The PubMed and Embase databases were searched for studies of smoking and diverticular disease up to 19 February 2016. Prospective studies that reported adjusted relative risk (RR) estimates and 95% confidence intervals (CIs) of diverticular disease associated with current or previous smoking were included. Summary RRs were estimated using a random effects model.
RESULTS
We identified five prospective studies which comprised 6076 cases of incident diverticular disease (diverticulosis and diverticulitis) among 385 291 participants and three studies with 1118 cases of complications related to diverticular disease (abscess or perforation) among 292 965. The summary RR for incident diverticular disease was 1.36 (95% CI 1.15-1.61, I = 84%, n = 4) for current smokers, 1.17 (95% CI 1.05-1.31, I = 49%, n = 4) for former smokers and 1.29 (95% CI 1.16-1.44, I = 62%, n = 5) for ever smokers. The summary RR was 1.11 (95% CI 0.99-1.25, I = 82%, n = 4) per 10 cigarettes per day. Although there was some indication of nonlinearity there was a dose-dependent positive association with increasing number of cigarettes smoked per day. There was some evidence that smoking also increases the risk of complications of diverticular disease, but the number of studies was small.
CONCLUSION
The current meta-analysis provides evidence that tobacco smoking is associated with an increased incidence of diverticular disease and related complications.

Meta-Analysis Review
BACKGROUND
Oesophageal diverticula are rare outpouchings of the oesophagus which may be classified anatomically as pharyngeal (Zenker's), mid-oesophageal and epiphrenic. While surgery is indicated for symptomatic patients, no consensus exists regarding the optimum technique for non-Zenker's oesophageal diverticula. The aim of this study was to determine the outcome of surgery in patients with non-Zenker's oesophageal diverticula.
METHODS
PubMed, MEDLINE and the Cochrane Library (January 1990 to January 2016) were searched for studies which reported outcomes of surgery in patients with non-Zenker's oesophageal diverticula. Primary outcome measure was the rate of staple line leakage.
RESULTS
Twenty-five observational studies involving 511 patients (259 male, median age 62 years) with mid-oesophageal (n = 53) and epiphrenic oesophageal (n = 458) diverticula who had undergone surgery [thoracotomy (n = 252), laparoscopy (n = 204), thoracoscopy (n = 42), laparotomy (n = 5), combined laparoscopy and thoracoscopy (n = 8)] were analysed. Myotomy was performed in 437 patients (85.5%), and anti-reflux procedures were performed in 342 patients (69.5%). Overall pooled staple line leak rates were reported in 13.3% [95% c.i. (11.0-15.7), p < 0.001] and were less common after myotomy (12.4%) compared with no myotomy (26.1%, p = 0.002).
CONCLUSIONS
No consensus exists regarding the surgical treatment of non-Zenker's oesophageal diverticula, but staple line leakage is common and is reduced significantly by myotomy.
