Diverticular Inflammation and Complication Assessment classification, CODA score and fecal calprotectin in clinical assessment of patients with diverticular disease: A decision curve analysis.

BACKGROUND AND AIMS: The Diverticular Inflammation and Complication Assessment (DICA) classification and the Combined Overview on Diverticular Assessment (CODA) were found to be effective in predicting the outcomes of Diverticular Disease (DD). We ascertain whether fecal calprotectin (FC) can further aid in improving risk stratification. METHODS: A three-year international, multicentre, prospective cohort study was conducted involving 43 Gastroenterology and Endoscopy centres. Survival methods for censored observations were used to estimate the risk of acute diverticulitis (AD) in newly diagnosed DD patients according to basal FC, DICA, and CODA. The net benefit of management strategies based on DICA, CODA and FC in addition to CODA was assessed with decision curve analysis, which incorporates the harms and benefits of using a prognostic model for clinical decisions. RESULTS: At the first diagnosis of diverticulosis/DD, 871 participants underwent FC measurement. FC was associated with the risk of AD at 3 years (HR per each base 10 logarithm increase: 3.29; 95% confidence interval, 2.13-5.10) and showed moderate discrimination (c-statistic: 0.685; 0.614-0.756). DICA and CODA were more accurate predictors of AD than FC. However, FC showed high discrimination capacity to predict AD at 3 months, which was not maintained at longer follow-up times. The decision curve analysis comparing the combination of FC and CODA with CODA alone did not clearly indicate a larger net benefit of one strategy over the other. CONCLUSIONS: FC measurement could be used as a complementary tool to assess the immediate risk of AD. In all other cases, treatment strategies based on the CODA score alone should be recommended.

Diagnóstico y tratamiento de la enfermedad diverticular del colon derecho: revisión de conjunto / Diagnosis and management of right colonic diverticular disease: A review

El objetivo de esta revisión es definir las características clínico-patológicas y aclarar el tratamiento de la enfermedad diverticular del colon derecho. Es poco frecuente en Europa, Estados Unidos y Australia, y más común en Asia. Durante los últimos años, su incidencia ha aumentado en Occidente, con diferentes distribuciones entre poblaciones. Muchos estudios han mostrado que es difícil diferenciar antes de la cirugía los síntomas de presentación de esta enfermedad de los de la apendicitis, ya que los síntomas y signos son similares, por lo que no es infrecuente encontrarse con un diagnóstico incorrecto. Con estudios de diagnóstico por la imagen exactos es posible establecer un diagnóstico preoperatorio preciso a fin de evaluar una estrategia de tratamiento adecuada. Actualmente, el tratamiento de esta enfermedad no está bien definido, no se han propuesto recomendaciones claras y no se sabe si también se pueden aplicar las recomendaciones para la enfermedad diverticular del colon izquierdo. Varios autores han señalado que el tratamiento conservador es el mejor enfoque, incluso en caso de reincidencia, y que la cirugía solo estaría indicada en determinados casos

The aim of this narrative review is to define the clinical-pathological characteristics and to clarify the management of right colonic diverticular disease. It is rare in Europe, USA and Australia and more common in Asia. In the recent years its incidence has increased in the West, with various distributions among populations. Many studies have reported that it is difficult to differentiate the presenting symptoms of this disease from those of appendicitis before surgery, because the signs and symptoms are similar, so misdiagnosis is not infrequent. With accurate imaging studies it is possible to reach a precise preoperative diagnosis, in order to assess an accurate treatment strategy. Currently the management of this disease is not well defined, no clear guidelines have been proposed and it is not known whether the guidelines for left colonic diverticular disease can also be applied for it. Several authors have stated that conservative management is the best approach, even in case of recurrence, and surgery should be indicated in selected cases

The 5-year outcome of patients having incomplete colonoscopy.

AIM: Incomplete colonoscopy indicated for the detection of neoplasia occurs in 2-23% of patients, but there is little information on the long-term outcome of such patients. METHOD: All patients who underwent colonoscopy over 5 years at the Royal Liverpool University Hospital with a follow-up of up to 5 years were identified. RESULTS: The risk of colorectal cancer (CRC) was 2.9% (312/10 580) for all patients undergoing colonoscopy. For a failed colonoscopy, the risk was five-fold higher [14.3% (99/693)]. The mean age of the patients was 61 years and 58% were female. Following incomplete colonoscopy the risk of finding additional CRC, advanced colonic neoplasia and extracolonic neoplasia on subsequent investigation was 6.2%, 3.2% and 1.9%. The diagnostic yield on subsequent investigation for CRC or colonic polyps was 7% for repeat colonoscopy, 13.4% for computed tomography colonography, 10.3% for standard computed tomography and 1.8% for barium enema. In the 363 patients who were not offered a subsequent investigation, there was no further instance of CRC or CRC-related mortality over a 36-month period. CONCLUSION: Although the risk of CRC is higher in patients who have had a failed colonoscopy, a protocol approach of subsequent investigation should not replace clinical assessment on whether another test is necessary in the light of the good outcome of patients who were not subsequently investigated.

Presentation, distribution pattern, and management of diverticular disease in a Nigerian tertiary hospital.

BACKGROUND: Colonic diverticular disease is one of the most common and costly gastrointestinal disorders among industrialized societies, which have recently been described among Africans. Presentations and distribution pattern of the disease among Africans appeared to be different from that described among the Western population. We embark on this study aimed at evaluating the presentation, distribution pattern, and the management of diverticulosis in our tertiary health facility. MATERIALS AND METHODS: A prospective descriptive study of the cases of diverticular disease seen between January 2007 and December 2011 at Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife, Osun State, Nigeria. RESULTS: During the 5-year study period, 40 cases were seen. The patients were aged 41-85 years with a median age of 64 years. There were 29 (72.5%) male and 11 (27.5%) female with an average male to female ratio of 3:1. The most common presentation was bleeding per rectum in 28 (70%) patients, which mostly needed transfusion. Ten (25%) patients presented with recurring abdominal pain, whereas one (2.5%) patient presented with abdominal mass and features of intestinal obstruction. Thirty patients were diagnosed on colonoscopy, eight on barium enema, and two on computerized tomography scan. Thirty-four (85%) patients had a pancolonic disease. All the patients were placed on high fiber diet and antibiotics namely ciprofloxacin and metronidazole. Five patients had recurrence within 6 months of follow up, of which one had emergency colectomy. CONCLUSION: Diverticular disease is no longer a rare disease in Nigeria. It is a common cause of lower gastrointestinal bleeding in elderly patients. High index of suspicion for diverticular disease of the colon and its complications should increase in the country.

Uncomplicated diverticular disease is not a common cause of colonic symptoms.

BACKGROUND: Colonic diverticular disease is common among older individuals whereas colonic symptoms, such as those of irritable bowel syndrome, are frequent in the general population. AIM: To determine among patients in secondary care, if uncomplicated diverticular disease is a common cause of colonic symptoms. METHODS: Patients aged ≥50 years attending gastroenterology out-patient clinics or scheduled for colonoscopy or barium enema in a secondary care hospital were invited to take part. Those with structural gastrointestinal diseases were excluded. Participants completed a locally validated Rome II questionnaire on colonic symptoms. Patients with diverticular disease were compared with those without. RESULTS: Seven hundred and eighty four patients with no structural pathology other than diverticular disease or benign colonic polyps completed the study. A total of 744 patients underwent colonoscopy, 40 barium enema. Of these, 281 patients had diverticular disease. Among patients with and without diverticular disease, the frequency of abdominal pain, diarrhoea, constipation and irritable bowel syndrome were 123 (44%) and 226 (46%), 44 (16%) and 80 (17%), 38 (14%) and 80 (17%) and 66 (25%) and 119 (25%), respectively (N.S.). CONCLUSION: Uncomplicated colonic diverticular disease is not a common cause of colonic symptoms among patients in secondary care.

Diarrhea-predominant irritable bowel syndrome is associated with diverticular disease: a population-based study.

OBJECTIVES: A subset of patients with colonic diverticular disease have chronic gastrointestinal symptoms, and some have a clinical diagnosis of irritable bowel syndrome (IBS), but whether IBS and diverticular disease are linked is uncertain. We aimed to evaluate this association in the community. METHODS: A population-based, cross-sectional survey was conducted by mailing a valid symptom questionnaire to the eligible residents of Olmsted County, MN, aged 30-95 years. Colonic diverticular disease (diverticulosis and diverticulitis) was ascertained through a review of the complete medical history of all responders. Subjects with at least one relevant test (colonoscopy, computed tomography (CT) scan, CT colonography, or barium enema) were included. IBS was defined using Rome II criteria. RESULTS: Among 2,267 eligible respondents, there were 1,712 subjects who had undergone colon testing (76%): 919 women (54%); mean (+/-s.d.) age 65 (+/-11 years). Colonic diverticular disease was identified in 44.4% (95% confidence interval (CI) 42.1-46.8) of the subject. IBS was reported by 8.8% (95% CI 6.9-11.0) of men and 17.0% (95% CI 14.6-19.6) of women. After adjusting for age and gender, the presence of IBS was associated with an increased odds for diverticulosis (odds ratio (OR) =1.8, 95% CI 1.3-2.4) but not diverticulitis (OR=1.7, 95% CI 0.9-3.2). In those 65 years of age or older, the presence of IBS was associated with a ninefold higher odds for diverticulosis (OR=9.4, 95% CI 5.8-15.1). Relative to the non-IBS subgroup, diarrhea-predominant IBS and mixed IBS were significantly associated with an increased odds for diverticular disease (OR=1.9, 95% CI 1.1-3.2; OR=2.6, 95% CI 1.0-6.4, respectively). CONCLUSIONS: There is a significantly increased odds for colonic diverticulosis in subjects with IBS (relative to those without IBS). These results suggest that IBS and colonic diverticular disease may be connected.

Diverticulosis and acute diverticulitis.

Colonic diverticulosis is a common, usually asymptomatic, entity of Western countries, with an incidence that increases with age. When these diverticula become infected and inflamed, patients can present with a wide variety of clinical manifestations. Management of acute, uncomplicated diverticulitis can often be treated successfully with antibiotics alone and the decision to proceed with more aggressive measures such as surgical intervention is made on a case-by-case basis. The treatment algorithm for diverticular disease continues to evolve as the pathophysiology, etiology, and natural history of the disease becomes better understood.

[Surgical complications of the diverticular disease. A rare case of sigmoid-vaginal fistula]. / Le complicanze chirurgiche della malattia diverticolare: un raro caso di fistola sigmoido-vaginale.

The Authors report on a rare case of diverticular disease complicated by a sigmoid- vaginal fistula with personal considerations based on a review of literature. A 75 year old patient becomes to our observation suffering the lost of smelly vaginal secretions without fever or abdominalgia. In anamnesis hysterectomy cholecystectomy appendectomy and visceral adhesions lysis. Colonoscopy RX barium enema, gynaecological examination, vaginal buffer show diverticulis of colon sigma with sigmoid-vaginal fistula. After laparotomy, visceral adhesions lysis, it was done sigmoid- vaginal fistula resection with healing. Diverticular disease is a XX century pathology with incidence (for some authors) of 50% of population. Symptomatic forms affect 30-50% of patients (variable percentage based on age); the 1% of these need surgery. The colonic anatomical-functional disorder is the principal cause of diverticular disease that recognize the main localization in colon-sigma. Diverticulitis with pericolic inflammation are frequent complications; possible evolutions are local tamponed peritonitis, mechanical intestinal occlusion, hemorrhage from colonic wall and fistulas. Sigmoid-vaginal fistula is the most frequent in women previously treated with laparohysterectomy. The colonoscopy and RX barium enema are gold standard for instrumental diagnosis; the vaginography is diriment, urography excludes urological diseases. The surgical treatment is the fistula resection, with or without colonic resection. In consideration of the necessity of conservative surgery and on the basis of this case, the authors suggest, if it's possible, the simple fistula resection, although the literature report an high number of relapses.

Prevention of complications and symptomatic recurrences in diverticular disease with mesalazine: a 12-month follow-up.

In uncomplicated diverticular disease, treatment is aimed at relieving symptoms. The aim of the present study was to evaluate the efficacy of mesalazine for symptomatic relief of uncomplicated diverticular disease of the colon. Two hundred sixty-eight consecutive eligible outpatients (122 male, 146 female; age, 66.1 years; range, 31-81 years) were enrolled in four treatment schedules in a randomized fashion: Group R1 (66 patients), rifaximin, 200 mg bid; Group R2 (69 patients), rifaximin, 400 mg bid; Group M1 (67 patients), mesalazine, 400 mg bid; and Group M2 (66 patients), mesalazine, 800 mg bid. Treatments were administered for 10 days every month for 12 months. Clinical evaluations were performed at admission and at 3-month intervals for 12 months considering 12 clinical variables (upper and lower abdominal pain/discomfort, tenesmus, diarrhea, abdominal tenderness, fever, bloating, general illness, nausea, emesis, dysuria, bleeding) graded as 0 = no symptoms, 1 = mild, 2 = moderate, and 3 = severe. The Global Symptomatic Score (GSS) was calculated using the sum of each symptom score. Two hundred forty-four patients completed the 12- month study; 24 were discontinued (14 treated with rifaximin and 10 treated with mesalazine) either as voluntary dropouts or because they developed side effects and/or complications. Group M2 demonstrated a lower frequency of many symptoms after 6 and 12 months of treatment; the mean GSS was significantly lower in Group M2 after 6 and 12 months of therapy by both intention-to-treat and per-protocol analyses. Patients treated with mesalazine (Groups M1+M2) had a lower GSS than subjects treated with rifaximin (Groups R1+R2) during the 12-month follow-up period. We conclude that cyclic administration of mesalazine is effective for symptomatic relief of uncomplicated diverticular disease of the colon. Some symptoms showed greater improvement with mesalazine, 800 mg bid, than with the other treatment schedules.

[Diverticulosis--diverticulitis]. / Divertikulose--Divertikulitis.

Diverticular disease is a common disorder in the western world. The course of the illness is benign: At least 75% of all patients with diverticular disease remain asymptomatic life long. 10-20% develop clinical symptoms, usually painful diverticulitis. Diverticular disease is diagnosed clinically in most cases. Computed tomography (CT) has replaced contrast enema as the diagnostic procedure of choice for acute diverticulitis. Most patients with uncomplicated diverticulitis can be treated as outpatients Bowel rest, intravenous fluid therapy, broad spectrum antibiotics are treatment modelities if a patient has been hospitalized. Close follow-up is mandatory, especially in patients treated as outpatients. Failure to improve with conservative medical therapy warrants a diligent search for complications and surgical consultation. Surgery may be nessasary in a few of hospitalized patients. Commonly, the operation is performed in a single-stage procedure. Once the acute setting has passed, a colonoscopy should be electively performed to exclude competing diagnoses particularly colonic cancer.

The rare epidemiologic coincidence of diverticular disease and advanced colonic neoplasia.

BACKGROUND AND AIMS: In Western industrialised countries the prevalence of neoplastic colonic lesions and diverticular disease markedly increases with age. In contrast, the coincident occurrence of both diseases seems to fall below their individual epidemiologic estimates. Because directly comparing data are rare, this retrospective study evaluates the coincidence of neoplastic lesions and diverticular disease. PATIENT AND METHODS: A total of 1,838 patients from 1986 to 2000 were admitted to the study. For 1,326 patients-56% male (n=741), 44% female (n=585), mean age 64 (+/-11.83 SD)-with a resection due to colonic cancer, the documented findings of colonoscopy, colonic contrast enema, and/or histopathology were analysed with regard to the prevalence of colonic diverticulosis. In 512 patients--51% male (n=263), 49% female (n=249), mean age 60 (+/-12.59 SD)--with a colonic resection due to diverticulitis, the synchronous or metachronous occurrence of neoplastic colonic lesions was recorded using the database of the Tumour Centre, Aachen. To compare the observed results with published epidemiology, statistical analysis included age-referred binomial tests and an age-stratified analysis (Cochran-Mantel-Haenszel test). Odds ratios (OR) were also calculated. P<0.05 was considered to indicate locally statistical significance. RESULTS: In the cancer group, we found a statistically significant reduced rate of diverticula in nearly all age categories and the age-stratified analyses (corresponding OR 0.30-0.51). Consistently, the diverticulitis group revealed a statistically significant decreased rate of advanced colonic neoplastic lesion in nearly all age categories and all age-stratified analyses (corresponding OR 0.13-0.43). CONCLUSION: Our results indicate that patients with colonic neoplastic lesions or diverticular disease probably form heterogeneous groups. Because current results from molecular biology emphasize the impact of the extracellular matrix on the genesis of diverticulosis and colonic cancer, the observed heterogeneity could be an expression of a distinct composition of the local milieu.

Prospective comparison of air-contrast barium enema and colonoscopy in patients with fecal occult blood: a pilot study.

BACKGROUND: The utility of air-contrast barium enema and colonoscopy for evaluation of the colon has been debated. Air-contrast barium enema is less expensive and invasive than colonoscopy, but it also is less sensitive and specific. Further, although air-contrast barium enema may be less painful than colonoscopy, it often is poorly tolerated by patients. Thus, this study compared the sensitivity and the specificity of air-contrast barium enema and colonoscopy for detection of colonic lesions in patients with fecal occult blood. METHODS: Over a 30-month period, patients with fecal occult blood were recruited. Patients underwent standard air-contrast barium enema, followed by colonoscopy 7 to 14 days later. Colonoscopists were blinded to the results of air-contrast barium enema until the colonoscopy was completed, after which the results were disclosed. If the findings were discrepant, colonoscopy was repeated. RESULTS: A total of 100 patients were evaluated. Nine air-contrast barium enemas were reported to be inadequate, and the cecum was not intubated at colonoscopy in two patients. In the remaining patients, 5 cancers were identified (1 each cecum, transverse colon, descending colon, sigmoid colon, and rectum) by both studies. Sixty-six polypoid lesions were identified in 30 patients. Diverticula were identified in 42 patients by air-contrast barium enema and in 18 patients by colonoscopy. Air-contrast barium enema detected 3 of 36 polypoid lesions 5 mm or less in diameter, 5 of 15 adenomas 6 to 9 mm in size, and 4 of 15 adenomas 10 mm or greater in diameter (sensitivity 8%, 33%, and 27%, respectively). After excluding patients with diverticula, air-contrast barium enema detected 3 of 7 adenomas 10 mm or greater in size. Overall, 12 polypoid lesions or filling defects were identified by air-contrast barium enema that could not be verified by colonoscopy. The specificity of air-contrast barium enema for lesions 1.0 cm or greater in size was 100%; for those 6 mm or greater, it was 97%. CONCLUSIONS: Air-contrast barium enema accurately detects colon cancer and diverticula. Its sensitivity for detection of polypoid lesions or adenomas is poor and was confounded by the presence of diverticula.

Divertículo gigante de sigma: presentación de un caso y consideraciones sobre el manejo de esta rara complicación de la enfermedad diverticular / Giant sigmoid diverticulum

Presentamos un nuevo caso de esta entidad clínica, diagnosticado en el contexto de un cuadro séptico, con descompensación hidrópica de una cirrosis latente, fistulizado a íleon y tratado con drenajes percutáneos. El divertículo gigante de colon es una rara complicación de la enfermedad diverticular. La presentación clínica es variable, soliendo cursar con dolor y/o con masa abdominal. Aunque su etiología permanece especulativa, parece en relación con un mecanismo de pulsión en el divertículo. La radiografía simple de abdomen, el enema opaco y la tomografía axial computarizada ayudan al diagnóstico. La resección quirúrgica es el tratamiento de elección. Nuestro caso es el primero publicado tratado conservadoramente mediante drenajes percutáneos, dada la muy precaria situación clínica de la paciente (AU)

Divertículo gigante de sigmoides / Giant sigmoid diverticulum

Se presenta un caso de divertículo gigante de sigmoide, manifestado por enterorragia, cuyo diagnóstico se logró mediante el colon por enema. Se señala los síntomas más frecuentes y los medios de diagnóstico habitualmente empleados, y se hacen consideraciones acerca de la patogenia y el tratamiento, señalando la preferencia de la colectomía segmentaria con anastomosis primaria

Incidência de doença diverticular do intestino grosso em indivíduos näo chagásicos e em chagásicos com e sem megacólon / Incidence of diverticular disease of the large bowel in non-chagasic and chagasic individuals with and without megacolon

Com a finalidade de estudar a freqüência de associaçäo entre duas colopatias comuns entre nós, o megacólon chagásico e a doença diverticular, foram revistos enemas opacos de 243 pacientes com idade superior a 35 anos. Foi observada a presença de divertículos em 22 (21,6%) dos 102 indivíduos näo chagásicos, em dez (35,7%) dos 28 chagásicos sem megacólon e em 14 (12,4%) dos 113 chagásicos com megacólon. Houve diferença estatisticamente significante entre os dois grupos de chagásicos, mas näo entre cada um deles e o grupo de näo chagásicos. A incidência de divertículos no sigmóide do grupo de näo chagásicos foi significativamente maior do que no sigmóide dos outros dois grupos estudados. Nos pacientes com a associaçäo de megacólon e doença diverticular, os divertículos situaram-se, sem exceçäo, nas porçöes näo dilatadas do intestino grosso. Sugere-se que no cólon dilatado de chagásicos existem condiçöes totalmente desfavoráveis à gênese e/ou manutençäo de divertículos
