AIMS: The majority of the colorectal carcinomas (CRC) arise in a vast mucosal area built with columnar cells and mucus-producing goblet cells. These carcinomas evolve via the conventional (tubular/villous) adenoma-carcinoma pathway, or the serrated adenoma-carcinoma pathway. Much less frequently CRC arise in the gut-associated lymphoid tissue (GALT) mucosal domain via the third pathway of colorectal carcinogenesis. METHODS: All publications on human colorectal GALT carcinomas in the literature were reviewed...

Segmental colitis associated with diverticulosis (SCAD) is an inflammatory process that affects colonic luminal mucosa in segments that are also affected by diverticulosis. Its prevalence varies between 1.15% and 11.4% amongst those suffering from diverticular disease (DD). Being closely associated with DD, it is slightly commoner in males and usually presents in the sixth decade of life. Although the exact pathogenesis of SCAD is unknown, it is probably heterogeneous and includes mechanisms that also play a part in inflammatory bowel disease (IBD)...

Diverticulosis is defined by the presence of diverticula due to herniation of mucosa and muscularis mucosa through the muscularis propria at sites of vascular penetration in the colon and is asymptomatic in the vast majority affected. There are global differences of distribution, in Western industrialized societies, the most common site is in the left colon, but in Asia right sided diverticulosis predominates. Whilst present in 17.5% of a general population and 42% of all comers at endoscopy it is seen in 71% of those aged ≥80 years...

The genetics of isolated colonic Crohn's disease place it approximately midway between Crohn's disease with small intestinal involvement and UC, making a case for considering it as a separate condition. We have therefore systematically reviewed its epidemiology, pathophysiology and treatment. Key findings include a higher incidence in females (65%) and older average age at presentation than Crohn's disease at other sites, a mucosa-associated microbiota between that found in ileal Crohn's disease and UC, no response to mesalazine, but possibly better response to antitumour necrosis factor than Crohn's disease at other sites...

Diverticular disease is a common condition that is associated with variable presentations. For this review article, we performed a review of articles in PubMed through February 1, 2016, by using the following MeSH terms: colon diverticula, colonic diverticulitis, colonic diverticulosis, colonic diverticulum, colonic diverticula, and diverticula. Diverticula are structural alterations within the colonic wall that classically form "pockets" referred to as diverticula. Diverticula form from herniation of the colonic mucosa and submucosa through defects in the circular muscle layers within the colonic wall...

BACKGROUND: Colonoscopy is the gold standard investigation for the diagnosis of bowel pathology and colorectal cancer screening. Adenoma detection rate is a marker of high quality colonoscopy and a high adenoma detection rate is associated with a lower incidence of interval cancers. Several technological advancements have been explored to improve adenoma detection rate. A new device called Endocuff Vision™ has been shown to improve adenoma detection rate in pilot studies. METHODS/DESIGN: This is a prospective, multicenter, randomized controlled trial comparing the adenoma detection rate in patients undergoing Endocuff Vision™-assisted colonoscopy with standard colonoscopy...

REVIEW
Polychronis Pavlidis, Ingvar Bjarnason
Aspirin is in many ways a non- steroidal anti-inflammatory drug (NSAID) prototype. Similar to conventional NSAIDs the gastric side effects of aspirin are well studied. However its potential adverse effects on the small and large intestine are less well known and under- researched. Experimental studies support a pathogenic pathway leading to NSAID enteropathy involving the topical effects on the intestinal barrier (mucous layer, enterocytes) that lead to dysfunction and increased intestinal permeability followed by increased exposure to luminal triggers and acute inflammation...

OBJECTIVES: Studies on the association of acute lower gastrointestinal bleeding (ALGIB) and drugs are scarce. We aimed to investigate the association of drugs and ALGIB, especially regarding specific causes of ALGIB, and their role in the severity of ALGIB. MATERIALS AND METHODS: The study was prospective and included all patients undergoing colonoscopy in 2010 and 2013 at the National University Hospital of Iceland. Use of nonsteroidal anti-inflammatory drugs (NSAIDs), low-dose aspirin (LDA), and warfarin before ALGIB was registered...

BACKGROUND: Studies outside the United States have described a lower prevalence of diverticulosis in patients with inflammatory bowel disease (IBD) than in patients without IBD. The aim of this study was to assess the prevalence of diverticulosis and associated risk factors in patients with ulcerative colitis (UC) at a U.S. tertiary care center. METHODS: We performed a retrospective review of patients over 50 years of age who underwent screening or surveillance colonoscopy from January 2006 to December 2013...

PURPOSE OF REVIEW: Inflammatory bowel diseases (IBDs) represent a heterogeneous entity whose diagnosis is sometimes difficult to ascertain. Many pathological processes may mimic IBD phenotypes. Among the classical differential diagnoses are enteric infections and infestations as well as drug toxicity. However, recently, more specific differential diagnoses have been included, including monogenic causes of gastrointestinal tract inflammation, particularly in young children. The purpose of the present review is to describe the differential diagnosis of IBD, putting it in a specific clinical and demographic context...

Antonio Tursi
Diverticulosis of the colon is frequently found on routine colonoscopy, and the incidence of diverticular disease and its complications appears to be increasing. The role of colonoscopy in managing this disease is still controversial. Colonoscopy plays a key role in managing diverticular bleeding. Several techniques have been effectively used in this field, but band ligation seems to be the best in preventing rebleeding. Colonoscopy is also effective in posing a correct differential diagnosis with other forms of chronic colitis involving colon harbouring diverticula (in particular with Crohn's disease or Segmental Colitis Associated with Diverticulosis)...

BACKGROUND: Prostaglandin E2 (PGE2) is the dominant prostaglandin in the colon and is associated with colonic inflammation. PGE2 levels are regulated not only by cyclooxygenases (COX-1 and COX-2) but also by 15-hydroxyprostaglandin dehydrogenase (15-PGDH), the major PGE2-degrading enzyme. Information about the involvement of 15-PGDH in colonic inflammation is sparse. AIM: We thus aimed to determine the gene expression and immunoreactivity (IR) of COX-1, COX-2, and 15-PGDH in colonic mucosa from patients with diverse inflammatory disorders: ulcerative colitis (UC), Crohn's disease (CD), and acute diverticular disease (DD)...

Chronic inflammatory bowel disease (CIBD) infers ulcerative colitis, Crohns disease and the pathological spectrum between, encompassing indeterminate colitis in resections and IBDU on biopsy. Histological assessment remains the gold standard for CIBD diagnosis and yet there are many conditions that show pathological mimicry of CIBD. It cannot be overemphasised that context is a critical determinant of the pathological diagnosis in inflamed colorectal biopsies.The lecture will focus on drug-induced colitis, diverticular colitis, focal active colitis, microscopic colitis and secondary colitis...

OBJECTIVE: To determine if single nuclear polymorphisms (SNPs) in the TFNSF15 gene play a role in patients requiring surgery for diverticulitis. BACKGROUND: A role for a genetic predisposition in diverticulitis is suggested by its association with hereditary connective tissue disorders, youthful onset in some patients, and the observation of families with multiple affected individuals. The TNFSF15 gene has been associated with other inflammatory diseases affecting the colon such as medically refractory ulcerative colitis (UC), aggressive Crohn's disease (CD), and pouchitis after restorative proctocolectomy...

AIM: To evaluate the clinical usefulness of single-balloon endoscopy (SBE) in patients in whom a colonoscope was technically difficult to insert previously. METHODS: The study group comprised 15 patients (8 men and 7 women) who underwent SBE for colonoscopy (30 sessions). The number of SBE sessions was 1 in 7 patients, 2 in 5 patients, 3 in 1 patient, 4 in 1 patient, and 6 in 1 patient. In all patients, total colonoscopy was previously unsuccessful. The reasons for difficulty in scope passage were an elongated colon in 6 patients, severe intestinal adhesions after open surgery in 4, an elongated colon and severe intestinal adhesions in 2, a left inguinal hernia in 2, and multiple diverticulosis of the sigmoid colon in 1...

Collagenous and lymphocytic colitis are common causes of chronic watery diarrhea that are characterized by distinct histopathologic abnormalities without endoscopically visible lesions and are summarized as microscopic colitis. Several variants of microscopic colitis have been described, although their clinical significance still has to be defined. Preserved mucosal architecture is a histologic hallmark of microscopic colitis and distinguishes the disease from inflammatory bowel disease (IBD). In addition to architectural abnormalities, the diagnosis of IBD rests on characteristic inflammatory changes...
