Furthermore, the incidence of diverticular disease appears to be increasing with aging. Therefore, it is associated with a significant economic burden in terms of health-care costs, hospitalization, and resource utilization not only in Western but also in Asian countries. Diverticular disease is responsible for a high number of gastrointestinal admissions and clinical visits. The incidence of diverticular disease is increasing over time in both Western and Asian countries. Diverticular disease is defined as clinically significant and symptomatic diverticulosis complicated by diverticulitis, diverticular bleeding, segmental colitis associated with diverticula, or symptomatic uncomplicated diverticular disease these are the so-called complications of colonic diverticulosis. The prevalence of colonic diverticulosis is increasing in Western and Asian countries. Therefore, diverticular disease is associated with a significant economic burden in terms of health-care costs and resource utilization. Diverticular disease with complications requires admission and operation moreover, it recurs frequently. Diverticular bleeding is predominantly located on the right side in Western countries, and both-sided diverticulosis increases the risk of bleeding in Asian countries. Key Messages: In Western countries, diverticulosis and diverticulitis are predominantly located on the left side of the colon, whereas they are predominantly present on the right side of the colon in Asian countries. In Asian countries, age greater than 70 years and both-sided diverticulosis increase the bleeding risk. The right colon is the source of diverticular bleeding in more than 50% of patients in Western countries. The incidence of diverticular bleeding also increases with age. The overall complication rate is higher in left-sided than in right-sided diverticulitis. Diverticulitis is predominantly located on the left side of the colon in Western countries, while it is predominantly located on the right side of the colon in Asian countries. The incidence of diverticulitis also increases with age. Most cases of diverticulosis in Western countries involve the left side of the colon, while diverticulosis is predominantly present on the right side of the colon in Asian countries. Summary: The incidence of diverticulosis increases with age. Diverticular disease is a burdensome digestive disease, because it is a major cause of hospital admissions and is associated with significant health-care costs. Diverticulosis can be complicated by diverticulitis and diverticular bleeding. 2017 6:418–424.Background: Colonic diverticulosis is prevalent and increasing not only in Western but also in Asian countries. The role of self-expandable metallic stents as “bridge to surgery” for the treatment of acute malignant colorectal obstruction. Gallo G, Sammarco G, Chiriatti AP, Calabria F, Sacco R. Systematic evaluation of surgical strategies for acute malignant left-sided colonic obstruction. 1994 81(9):1270–1276.īreitenstein S, Rickenbacher A, Berdajs D, Puhan M, Clavien PA, Demartines N. Predictors of complications and mortality in patients with self-expanding metallic stents for the palliation of malignant colonic obstruction. Preoperative stenting in colonic flexura tumors is associated with faster healing, less postoperative complications, lower rates of colostomy, and higher rates of minimally invasive surgery, and can be safely used at experienced centers.Ĭolonic stenting Colorectal cancer Flexura tumors Minimally invasive surgery Obstruction. Three of them underwent laparoscopic surgery and eleven underwent open surgery. Seven of the patients were stented for palliative purposes. Splenic flexure tumors were detected in 18 patients and hepatic flexure tumors in 3 patients. The mean age of the patients was 62 years, and the ratio of females to males was 3:18. The expandable metal stent (Wallflex®, Boston Scientific, Marlborough, MA, USA) was placed at the obstruction through the lead wire. Patients admitted to the emergency department for obstructive colonic tumors between 20 were retrospectively evaluated, and 21 patients treated using stents were included in the study. In this study, we aimed to retrospectively screen patients with flexure tumors admitted to our clinic who were treated using a colonic stent and discuss our findings. However, placing a stent in the flexure tumors is rare because it is technically more difficult. Colonic stenting in left-sided tumor is being commonly used.
