The Risk Factors for Colonic Diverticular Bleeding / 대한소화기학회지

BACKGROUND/AIMS: Colonic diverticular bleeding cases account for 30-40% of the lower gastrointestinal bleeding, among which, 3-5% appear to be massive bleeding. The purpose of this study was to evaluate the risk factors for colonic diverticular bleeding diagnosed by colonoscopic examination. METHODS: Among the 1,003 patients, who were identified to have colonic diverticulosis including sleeding by diverticulitis and diverticular bleeding coding search, 216 patients had diverculosis, and they were divided into two groups: one with diverticular bleeding, and the other without bleeding. We evaluated the potential risk factors for diverticular bleeding, based on age, gender, location of diverticulum, comorbidities related to atherosclerosis, smoking, alcohol and medications, and compared them between both groups. RESULTS: Among the 216 patients, we observed colonic diverticular bleeding in 35 patients (16.2%). The mean age of the bleeding group was significantly older than that of non-bleeding group. No difference was observed regarding gender ratio. Right colonic diverticula were common in both groups, but there were higher proportion of patients with bleeding in bilateral diverticuosis. Old age, bilateral diverticulosis, presence of atherosclerosis related diseases (hypertension, diabetes mellitus, ischemic heart disease, obesity), use of aspirin, NSAIDs and calcium channel blocker, increased the risk of bleeding. In a multivariate analysis, use of aspirin and bilateral diverticulosis were identified as independent risk factors for colonic diverticular bleeding. CONCLUSIONS: Since the patients who took aspirin and/or had bilateral colonic diverticulosis increased the risk of bleeding from divertuculi. As such, caution and education of patients are required.

Prevalencia de enfermedad diverticular del apéndice cecal en pacientes apendicectomizados por apendicitis aguda / Diverticular disease of the appendix in appendectomies

Introduction: Diverticular disease of the appendix is an infrequent finding in the study of surgical specimens from patients operated on for clinically suspected acute appendicitis. Our aim was to determine the prevalence of diverticular disease of the appendix in patients who underwent appendectomies based on the clinical diagnosis of acute appendicitis. Material and Method: Design: Cross-sectional study. Inclusion criteria: Patients who underwent appendectomies based on a clinical diagnosis of acute appendicitis. Studyperiod: january 2000 to december 2008. Sampling: Non-probabilistic sampling of consecutive cases. Methodology: A review was conducted of the clinical records and surgical specimens from patients who underwent appendectomies based on a clinical diagnosis of acute appendicitis. Results: Within the study period, 11.472 appendectomies were performed based on a clinical diagnosis of acute appendicitis. Ninety-four patients presented diverticular disease of the appendix (0.8 percent). The median age was 40 years and 62.8 percent were male. The disease appeared as: appendicular diverticulitis (45.7 percent), appendicular diverticulosis with acute appendicitis (28.7 percent), appendicular diverticulitis with acute appendicitis (17.0 percent), appendicular diverticulosis (5.3 percent), and appendicular pseudodiverticulosis with acute appendicitis (3.2 percent). Operative morbidity was 12.7 percent. One patient presented an adenocarcinoma of the appendix associated with diverticular disease. Conclusion: The prevalence of diverticular disease of the appendix is low in our population and the characteristics are different to reported by other authors.

Introducción: La enfermedad diverticular del apéndice cecal es un hallazgo infrecuente en apendicectomizados por sospecha clínica de apendicitis aguda. Nuestro objetivo es evaluar la prevalencia de enfermedad diverticular del apéndice cecal en pacientes apendicectomizados por sospecha clínica de apendicitis aguda. Material y Método: Diseño de estudio: Estudio de corte transversal. Criterios de inclusión: Pacientes apendicectomizados por sospecha clínica de apendicitis aguda. Período de estudio: enero de 2000 a diciembre de 2008. Muestreo: No probabilístico de casos consecutivos. Metodología: Se realizó una revisión de los registros clínicos y de las piezas quirúrgicas de los pacientes sometidos a apendicectomía por diagnóstico clínico de apendicitis aguda. Resultados: Se estudiaron 11.472 apendicectomías. Noventa y cuatro pacientes presentaron enfermedad diverticular del apéndice (0,8 por ciento). La mediana de edad fue 40 años y el 62,8 por ciento fue género masculino. La enfermedad se presentó como: diverticulitis apendicular (45,7 por ciento), diverticulosis apendicular con apendicitis aguda (28,7 por ciento), diverticulitis apendicular con apendicitis aguda (17,0 por ciento), diverticulosis apendicular (5,3 por ciento) y pseudodiverticulosis apendicular con apendicitis aguda (3,2 por ciento). La morbilidad operatoria fue 12,7 por ciento. Un paciente presentó un adenocarcinoma del apéndice cecal asociado a la enfermedad diverticular del apéndice. Conclusión: La prevalencia de enfermedad diverticular del apéndice cecal es baja en nuestra población y con características que difieren a lo reportado por otros autores.

Diverticulitis aguda / Acute diverticulitis

La diverticulitis aguda es una enfermedad que ocurre como consecuencia de la perforación de un divertículo del colon, lo cual genera un proceso mórbido que puede desencadenar serias complicaciones como abscesos, flemones, abdomen agudo quirúrgico. Puede presentarse inicialmente como un dolor crónico en el cuadrante inferior izquierdo en pacientes con un estilo de vida con marcado stress por sus múltiples actividades, en personas que consumen dieta baja en fibra lo que provoca también incremento de la presión intraluminal...

Association between Diverticulosis and Colonic Neoplasm in Koreans / 대한소화기학회지

BACKGROUND/AIMS: Although a few published studies have reported on the relationship between diverticulosis and neoplasia in the west, it is not yet examined in Korea. The aim of this study was to determine whether there is an association between diverticulosis and colonic neoplasia. METHODS: We retrospectely analysed the medical records of 3,007 patients (M:F=1.3:1) who underwent colonoscopic examinations from year 2002 to year 2004. Patients who had a history of previous polypectomy, colon resection, or inflammatory bowel diseases were excluded. The size, extent (none, few, or many), and location of diverticuli and polyps were analyzed. RESULTS: Of 2,377 patients, included 57% were male and the mean age was 50.8 year-old. Nine percent of the patient had diverticulosis, 29% had more than one neoplasm, and 6% had advanced neoplasia. Patients with diverticular diseases had higher risks of any neoplasia than those without diverticulum (p=0.03, 37.7% vs. 28.2%). There was no correlation between diverticular diseases and advanced neoplasia. Patients with proximal diverticular diseases had higher risk of any proximal neoplasia than other patients (p<0.01 24.6% vs. 14.3%). Moreover, they had higher risk of proximal advanced neoplasia than others (p=0.01, 4.5% vs. 2%). In addition, comparison of multiple diverticular disease with few or no diverticuli revealed no difference in the risk of any neoplasia. CONCLUSIONS: These data show that the patients with diverticular diseases have more neoplasms than controls without diverticula.

Colonic diverticulosis in India: the changing scene.

BACKGROUND: The prevalence of colonic diverticulosis has a wide geographic and ethnic variation and has been considered to be quite low in India. This study was aimed at determining the prevalence of colonic diverticulosis in northern India based on barium enema examination in symptomatic patients. METHODS: All barium enema examinations performed between January 1985 and December 1991 were reviewed for the presence of colonic diverticulosis. Clinical data of such patients were retrieved. RESULTS: 51 (3.2%) of 1610 barium enema studies showed colonic diverticulosis. The frequency of diverticulosis in barium studies increased from 0.3% among subjects in the third decade to 32.4% in patients above 60 years. Most patients were city dwellers, vegetarians and belonged to the upper socio-economic stratum. Twenty patients (39.2%) presented with a complication; the spectrum of such patients was no different from that reported from the West. While the sigmoid colon was the commonest site of diverticuli, there was a relative preponderance of right sided diverticuli as compared to the Western experience. Seven patients with complications required surgical treatment, while the rest were managed conservatively. CONCLUSION: Colonic diverticulosis and its complications are not rare in India and should be considered in the differential diagnosis of abdominal disorders.
