INTRODUCTION
Colovesical fistulas (CVFs) account for approximately 95% enterovesical fistulas (EVFs). About 2/3 CVF cases are diverticular in origin. It mainly presents with urological signs such as pneumaturia and fecaluria. Diagnostic investigations aim at confirming the presence of a fistula. Although conservative management can be chosen for selected individuals, most patients are mainly treated through surgical interventions. CVF represents a challenging condition, which records high rates of morbidity and mortality. Our systematic review aimed at achieving deeper knowledge of both indications, in addition to short- and long-term outcomes related to CVF management.
EVIDENCE ACQUISITION
We performed a systematic literature review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA) guidelines. Pubmed/MEDLINE, Embase, Scopus, Cochrane Library and Web of Science databases were used to search all related literature.
EVIDENCE SYNTHESIS
The 22 included articles covered an approximately 37 years-study period (1982-2019), with a total 1365 patient population. CVF etiology was colonic diverticulitis in most cases (87.9%). Pneumaturia (50.1%), fecaluria (40.9%) and urinary tract infections (46.6%) were the most common symptoms. Abdomen computed tomography (CT) scan (80.5%), colonoscopy (74.5%) and cystoscopy (55.9%) were the most frequently performed diagnostic methods. Most CVF patients underwent surgery (97.1%) with open approach (63.3%). Almost all patients had colorectal resection with primary anastomosis with or without ostomy and 53.2% patients underwent primary repair or partial/total cystectomy. Four percent anastomotic leak, 1.8% bladder leak and 3.1% reoperations rates were identified. In an average 5-68-month follow-up, overall morbidity, overall mortality and recurrences rates recorded were 8-49%, 0-63% and 1.2%, respectively.
CONCLUSIONS
CVF mainly affects males and has diverticular origin in almost all cases. Pneumaturia, fecaluria and urinary tract infections are the most characteristic symptoms. Endoscopic tests and imaging are critical tools for diagnostic completion. Management of CVFs depends on the underlying disease. Surgical treatment represents the final approach and consists of resection and reanastomosis of offending intestinal segment, with or without bladder closure. In many cases, a single-stage surgical strategy is selected. Perioperative and long-term outcomes prove good.

Review
Colonic diverticulosis is one of the most common conditions of the digestive system and patients generally remain asymptomatic. However, about 20% of patients develop symptomatic diverticular disease such as acute diverticulitis or diverticular hemorrhage, and these have become a huge burden on healthcare systems worldwide. Recent understanding of the pathophysiology of diverticulosis and diverticular disease suggests the role of multiple factors including genetic and environment. Based on this understanding, a preventive strategy to reduce the risk factors of diverticulosis and diverticular disease is highly recommended. The diagnosis of the acute diverticulitis relies on imaging modalities such as an abdominal-pelvic CT scan together with symptoms and signs. Treatment of diverticular disease should be individualized and include modification of lifestyle, use of antibiotics, and surgery. Recent guidelines recommend pursuing less aggressive treatment for patients with acute diverticulitis. This review will provide an overview of both the existing and evolving understanding regarding colonic diverticulosis and diverticular disease and can help clinicians in the management of their patients with diverticular disease.

Review
Diverticular disease is a common clinical problem, particularly in industrialized countries. In most cases, colonic diverticula remain asymptomatic throughout life and sometimes are found incidentally during colonic imaging in colorectal cancer screening programs in otherwise healthy subjects. Nonetheless, roughly 25% of patients bearing colonic diverticula develop clinical manifestations. Abdominal symptoms associated with diverticula in the absence of inflammation or complications are termed symptomatic uncomplicated diverticular disease (SUDD). The pathophysiology of diverticular disease as well as the mechanisms involved in the shift from an asymptomatic condition to a symptomatic one is still poorly understood. It is accepted that both genetic factors and environment, as well as intestinal microenvironment alterations, have a role in diverticula development and in the different phenotypic expressions of diverticular disease. In the present review, we will summarize the up-to-date knowledge on the pathophysiology of diverticula and their different clinical setting, including diverticulosis and SUDD.

In this session different problems regarding the pathogenesis of diverticular disease were considered, including "Genetics", "Neuromuscular function abnormalities", "Patterns of mucosa inflammation", and "Impact of lifestyle". The patients affected by diverticular disease have clear genetic pattern, that might predispose to the occurrence of the disease as well as to its complications. Neuromuscular abnormalities may be recognized already at the stage of diverticulosis, and inflammation may explain symptoms occurrence in symptomatic uncomplicated diverticular disease (SUDD) or symptoms persistence after an episode of acute diverticulitis. Finally, lifestyle might also have an impact on symptoms' occurrence. Specifically smoking, but also obesity seem to play an important role, while the role of low-fiber diet and constipation is now under debate.

Ehlers-Danlos syndrome (EDS) is a group of hereditary connective tissue disorders which are clinically characterized by hypermobility of joints, hyperelasticity of skin and tissue insufficiency, sometimes leading to herniation, bleeding, and organ rupture. This is a case report of a 55-year-old man with EDS and a big bladder diverticulum in which we discuss treatment strategy in patients with EDS and bladder diverticula. Initially, treatment approach should be conservative due to high recurrence rates and potential complications following surgical procedures. Invasive procedures - preferably minimally invasive - may be indicated, based on an individual risk evaluation.

We report a rare complication involving a healthy 45-year-old male patient who underwent an emergency laparoscopic appendicectomy for acute perforated gangrenous appendicitis. The patient was catheterised pre- procedure and the ports were inserted under vision. Upon completion of the procedure, a 15 Fr Robinson drain was left in the pelvis and was fed through the suprapubic port hole. Postoperatively the patient developed worsening, generalised abdominal pain and high output from the drain. The patient was re-catheterised but the computed tomography (CT) cystogram did not show any injury to the bladder. The drain fluid creatinine was noted to be raised (>4,000), indicating that urine was leaking into the drain. Conventional cystogram confirmed a contrast leak from the dome around the drain. Flexible cystoscopy confirmed that the drain had transversed the vesicourachal diverticula. The drain was pulled back and converted to a suprapubic catheter with the patient subsequently being discharged. Vesicourachal diverticula is a rare and often asymptomatic anomaly. When undertaking laparoscopic surgery, precautions should be taken to prevent port site injury such as catheterising the patient to ensure the bladder is empty and inserting the ports under direct vision. It is safer to visualise muscle rather than peritoneum during port insertion. In this case, the bladder diverticula was noticed extraperitoneally. Though the indirect CT cystogram reported no injury, this was unreliable as the bladder was not distended which led to the subtle injury being missed. Traditional cystogram should be considered in cases with a negative CT cystogram and a strong suspicion of bladder injury.

Meckel's diverticulum is the most common congenital gastrointestinal defect with a prevalence of 2%. It is mostly asymptomatic and it rarely causes acute abdomen in adults. In this case report, a 28-year-old male with no previous abdominal surgery presented with clinical symptoms of small bowel obstruction. Surgery revealed a Meckel's diverticulum adherent to the abdominal wall, causing internal herniation with small bowel obstruction. The diverticulum was openly resected and no post-operative complications occurred. Laparoscopy seems safe, and surgical removal of the symptomatic Meckel's diverticulum is recommended.

Review
Esophageal intramural pseudodiverticulosis (EIPD) is a disease of unknown pathogenesis characterized by usually systemic, cystic dilatation of the excretory ducts of esophageal submucosal glands. In this article, I review the epidemiology, clinical manifestations, endoscopic findings, esophagographic findings, and histopathology of EIPD. I also discuss the etiology and possible pathogenesis of EIPD based on my experiences with this disease and a review of the literature. EIPD usually presents with dysphagia in middle-aged individuals. It is often complicated with secondary infections, most commonly candidiasis. On esophagography, EIPD is delineated as small, multiple, flask-shaped outward projections within the esophageal wall. In recent years, EIPD has been mainly diagnosed by endoscopic findings of multiple, localized, small mucosal depressions. The orifices of the "pseudodiverticula" periodically open and close, and excrete mucus onto the mucosal surface. On histopathological examination, the luminal surface of dilated ducts in EIPD is covered by multilayered, hyperplastic epithelial cells, but myoepithelial cells in the glandular acini are well preserved. Treatment of EIPD is usually symptomatic therapy, and prevention of the infectious complications is important. The etiology and pathogenesis of EIPD are largely unknown, but functional abnormalities of autonomic nerve fibers innervating the esophageal glands likely play an important role, since the structures of the glands are basically preserved in this disease.
