Eosinophils contribute to tissue homeostasis, damage, and repair. The mucosa of colonic diverticula has not been evaluated for eosinophils by quantitative histology. We aimed to investigate whether mucosal eosinophils and other immune cells are increased in colonic diverticula.
METHODS
Hematoxylin and eosin stained sections from colonic surgical resections (n = 82) containing diverticula were examined. Eosinophils, neutrophils, and lymphocytes, in five high power fields in the lamina propria were counted at the base, neck, and ostia of the diverticulum and counts compared to non-diverticula mucosa. The cohort was further subgrouped by elective and emergency surgical indications.
RESULTS
Following an initial review of 10 surgical resections from patients with diverticulosis, a total of 82 patients with colonic resections containing diverticula from the descending colon were evaluated (median age 71.5, 42 M/40F). Eosinophil counts for the entire cohort were increased in the base and neck (median 99 and 42, both P = <0.001) compared with the control location (median 16). Eosinophil counts remained significantly increased in the diverticula base (both P = <0.001) and neck (P = 0.01 and <0.001, respectively) in both elective and emergency cases. Lymphocytes were also significantly increased at the diverticula base compared to controls in both elective and emergency subgroups.
CONCLUSION
Eosinophils are significantly and most strikingly increased within the diverticulum in resected colonic diverticula. While these observations are novel, the role of eosinophil and chronic inflammation is as yet unclear in the pathophysiology of colonic diverticulosis and diverticular disease.

Review
OBJECTIVE
Urethral diverticulum is a rare, yet important condition for the female pelvic surgeon. We aimed to characterize the women who have been seen for this condition across the three Mayo Clinic locations.
METHODS
Medical record review was performed for patients across all three Mayo Clinic sites (Rochester, Arizona, Florida) that had International Classification of Diseases, Ninth Revision, (ICD-9) and International Classification of Diseases, Tenth Revision, (ICD-10) codes corresponding to urethral diverticulum (ICD-9, 599.2; ICD-10, N36.1). We also performed a review of patients who underwent urethral diverticulectomy via Current Procedural Terminology (CPT) code 53235. Data were available for patients from June 1, 2003, to October 5, 2018. Patients were classified by age, etiology, presenting symptomatology, location, treatment, pathology, and postoperative outcomes.
RESULTS
Four hundred forty-seven women met initial coding criteria for urethral diverticula, with 228 women having documented urethral diverticula. The most common presentations were irritative voiding symptoms (93) and infections (92). The most common diagnostic modality was radiographic imaging (198/228) with magnetic resonance imaging accounting for 157 cases. Etiology was unknown in the majority of cases (181/228). Of women who were diagnosed, 172 underwent diverticulectomy with 51 concurrent urethral sling placements. Final pathology demonstrated 2 cases of malignancy. Postoperative follow-up ranged from 0 months to 15 years (mean, 1.4 years; median, 4 months). Forty-three patients had persistent urinary symptoms after diverticulectomy with stress incontinence being the most common. Eight patients underwent subsequent sling placement. Fourteen patients had recurrence.
CONCLUSIONS
This appears to be the largest reported series on female urethral diverticula, a rare yet important entity that requires special consideration. Most surgical cases found resolution of symptoms after diverticulectomy. Importantly, less than 2% of urethral diverticula were associated with malignancy.

Review
PURPOSE OF REVIEW
Pharyngoesophageal diverticuli such as Zenker's diverticulum are relatively rare diseases that may have a significant impact on a patient's quality of life. Open surgical techniques have historically been the mainstay of treatment for Zenker's diverticuli and remain the preferred approach for many surgeons operating on Killian-Jamieson diverticuli (KJD) and pharyngoceles. However, advances in technology in recent decades have allowed for the development of successful endoscopic surgical techniques for the management of these conditions.
RECENT FINDINGS
Endoscopic management of Zenker's diverticulum with carbon dioxide laser-assisted diverticulotomy or endoscopic stapler-assisted diverticulostomy has gained wide acceptance in recent years. This is based on studies showing high rates of successful outcomes, low rates of complications and shorter operative time with an associated impact on overall cost and patient recovery. Endoscopic management of KJD and pharyngoceles has recently been described, but remains controversial with many surgeons preferring open surgical approaches for the ability to identify and protect the recurrent laryngeal nerve.
SUMMARY
Open and endoscopic techniques are accepted for the treatment of Zenker's diverticulum with open approaches remaining the traditional technique for management of non-Zenker's diverticulum. Further investigation of endoscopic approaches for management of KJD is necessary to assess safety and efficacy.

OBJECTIVE
Large congenital bladder diverticula (LCBD), congenital bladder diverticula (CBD) larger than 2 cm diameter, is a rare anomaly. The aim of this study was to report long-term surgical and clinical outcomes of children with LCBD.
METHODS
Medical charts of all children who were diagnosed with LCBD at our institution between April 2005 and December 2017, with at least 2 year follow-up were retrospectively reviewed. Patients' demographics, symptoms, operative technique, diverticulum size and localization, surgical outcomes and complications were recorded.
RESULTS
Fourteen patients with 18 LCBD, all male and age between 7 and 240 months (mean age: 53.5 months) were included in the study. Urinary tract infection was the main complaint in 10. Vesicoureteral reflux was detected in eight patients. Diverticula were 2-5.5 cm (mean 3.3 cm) in size. All diverticulectomies were performed transvesically and ureteroneocystostomy was added in 12 patients, 5 of whom were bilateral. No postoperative infection or recurrent reflux were observed. The median follow-up period was 4.5 years (2-12 years).
CONCLUSION
Treatment of LCBD is mostly surgical and transvesical approach for diverticulectomy was found to be a safe and effective surgical procedure in long term follow-up.

Review
Jejunal diverticulosis is a rare entity with variable clinical and anatomical presentations. The majority of cases are discovered incidentally during radiological investigations. Based on a case of a 77 year old woman with jejunal diverticulitis, the current literature about small bowel diverticulosis is reviewed. A jejunoileal diverticulum is usually uncomplicated and can be treated conservatively. Serious complications that require surgery can occur. Abdominal CT is the preferred diagnostic tool.

Review
The importance of venous structure in the heart is usually overshadowed by that of the arterial system. Coronary sinus (CS) is a part of cardiac venous apparatus and connects left atria to the right atria. Other than having role in physiological contractions of both atria, it contributes substantially to cardiac electrical conduction system. Due to unique placement and connections of the CS, it has become growing interest in clinical cardiology. It is used in cardiac resynchronization therapy with biventricular pacing, left-sided catheter ablation of arrhythmias, and administration of retrograde cardioplegia in cardiac surgery. In some individuals, CS is presented with anatomical variants. CS diverticulum is a congenital outpouching that provides muscular connection between atria and ventricle. This connection provides a suitable substrate for occurrence of arrhythmias, which even results in life-threatening events such as sudden cardiac death. Early diagnosis leads to treatment with ablation techniques, which ultimately eliminates origins of arrhythmias.

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.

Diverticulosis is frequently accompanied by altered bowel habits. The biogenic amines within colonic mucosa control bowel motility, and in particular, alterations in serotonin signaling may play a role in colon diverticulosis. The aim of the study was to assess the concentration of biogenic amines and serotonin receptor expression in the colonic mucosa in patients with diverticulosis and healthy controls. This prospective, comparative study included 59 individuals: 35 with sigmoid diverticulosis and 24 healthy controls. The study was held at the Department of Gastroenterology and Internal Medicine, Medical University of Warsaw, Poland. Mucosal samples were taken from the right and left colon during a colonoscopy in all patients. Concentrations of norepinephrine, 3-methoxy-4-hydroxyphenylglycol, dopamine, homovanillic acid, serotonin, and 5hydroxyindoleacetic acid were measured with high-performance liquid chromatography. Expressions of human 5-hydroxytryptamine receptor 3A, 5-hydroxytryptamine receptor 4, 5-hydroxytryptamine receptor 7, solute carrier family 6 member 4 (SERT) for serotonin, as well as the neuroglia activation markers glial fibrillary acidic protein, S100 calcium-binding protein B, and proteolipid protein 1, were assessed with polymerase chain reaction. The median age and sex distribution were comparable in both study groups (median 69 y vs. 52 y; < 0.455 and males/females in cases 11/17 vs. 18/19 in controls; < 0.309). In diverticulosis patients, there was a higher concentration of serotonin in the left affected colon compared to the right healthy part of the colon (median 8239 pg/mg vs. 6326 pg/mL; < 0.01). The expression was lower in the affected left segment compared to the right colon (median 0.88 vs. 1.36; < 0.01). There was a higher colonic mucosa concentration of serotonin (median 8239 pg/mg vs. 6000 pg/mL; < 0.02) and 5hydroxyindoleacetic acid/serotonin ratio (median 0.27 vs. 0.47; < 0.01) in diverticulosis patients compared to controls in the left side of the colon. The concentration of serotonin in the mucosa of the colon segment affected by diverticula is higher than in the healthy segment in the same individuals and higher than in healthy controls. These results underline serotonin signaling in colon diverticulosis pathophysiology.
