| 1 | Impact of discontinuing non-steroidal antiinflammatory drugs on long-term recurrence in colonic diverticular bleeding显示文摘AIM: To determine the effect of discontinuing nonsteroidal antiinflammatory drugs(NSAIDs) on recurrence in long-term follow-up patients with colonic diverticular bleeding(CDB).METHODS: A cohort of 132 patients hospitalized for CDB examined by colonoscopy was prospectively enrolled. Comorbidities, lifestyle, and medications(NSAIDs, low-dose aspirin, antiplatelet agents, anticoagulants, acetaminophen, and corticosteroids) were assessed. After discharge, patients were requested to visit the hospital on scheduled days during the followup period. The Kaplan-Meier method was used to estimate recurrence.RESULTS: Median follow-up was 15 mo. The probability of recurrence at 1, 6, 12, and 24 mo was 3.1%, 19%, 27%, and 38%, respectively. Of the 41 NSAID users on admission, 26(63%) discontinued NSAID use at discharge. Many of the patients who could discontinue NSAIDs were intermittent users, and could be switched to alternative therapies, such as acetaminophen or an antiinflammatory analgesic plaster. The probability of recurrence at 12 mo was 9.4% in discontinuing NSAID users compared with 77% in continuing users(P < 0.01, log-rank test). The hazard ratio for recurrence in the discontinuing NSAIDs users was 0.06 after adjusting for age > 70 years, right-sided diverticula, history of hypertension, and hemodialysis. No patients developed cerebrocardiovascular events during follow-up.CONCLUSION: There is a substantial recurrence rate after discharge among patients hospitalized for diverticular bleeding. Discontinuation of NSAIDs is an effective preventive measure against recurrence. This study provides new information on risk reduction strategies for diverticular bleeding. | Naoyoshi Nagata Ryota Niikura Tomonori Aoki Takuro Shimbo Katsunori Sekine Hidetaka Okubo Kazuhiro Watanabe Toshiyuki Sakurai Chizu Yokoi Junichi Akiyama Mikio Yanase Masashi Mizokami Naomi Uemura | 2015 | World Journal of Gastroenterology2015，21，4： | 1 |
| 2 | Risk factors for adverse in-hospital outcomes in acute colonic diverticular hemorrhage显示文摘AIM: To investigate the factors associated with transfusion, further bleeding, and prolonged length of stay.METHODS: In total, 153 patients emergently hospitalized for diverticular bleeding who were examined by colonoscopy were prospectively enrolled. Patients in whom the bleeding source was identified received endoscopic treatment such as clipping or endoscopic ligation. After spontaneous cessation of bleeding withconservative treatment or hemostasis with endoscopic treatment, all patients were started on a liquid food diet and gradually progressed to a solid diet over 3d, and were discharged. At enrollment, we assessed smoking, alcohol, medications [non-steroidal antiinflammatory drugs(NSAIDs)], low-dose aspirin, and other antiplatelets, warfarin, acetaminophen, and oral corticosteroids), and co-morbidities [hypertension,diabetes mellitus, dyslipidemia, cerebro-cardiovascular disease, chronic liver disease, and chronic kidney disease(CKD)]. The in-hospital outcomes were need for transfusion, further bleeding after spontaneous cessation of hemorrhage, and length of hospital stay.The odds ratio(OR) for transfusion need, further bleeding, and prolonged length of stay were estimated by logistic regression analysis.RESULTS: No patients required angiographic embolization or surgery. Stigmata of bleeding occurred in 18% of patients(27/153) and was treated by endoscopic procedures. During hospitalization, 40patients(26%) received a median of 6 units of packed red blood cells. Multivariate analysis revealed that female sex(OR = 2.5, P = 0.02), warfarin use(OR= 9.3, P < 0.01), and CKD(OR = 5.9, P < 0.01)were independent risk factors for transfusion need.During hospitalization, 6 patients(3.9%) experienced further bleeding, and NSAID use(OR = 5.9, P = 0.04)and stigmata of bleeding(OR = 11, P < 0.01) were significant risk factors. Median length of hospital stay was 8 d. Multivariate analysis revealed that age > 70years(OR = 2.1, P = 0.04) and NSAID use(OR = 2.7,P = 0.03) were independent risk factors for prolonged hospitalization(≥ 8 d).CONCLUSION: In colonic diverticular bleeding, female sex, warfarin, and CKD increased the risk of transfusion requirement, while advanced age and NSAID increased the risk of prolonged hospitalization. | Naoyoshi Nagata Ryota Niikura Tomonori Aoki Shiori Moriyasu Toshiyuki Sakurai Takuro Shimbo Katsunori Sekine Hidetaka Okubo Kazuhiro Watanabe Chizu Yokoi Junichi Akiyama Mikio Yanase Masashi Mizokami Kazuma Fujimoto Naomi Uemura | 2015 | World Journal of Gastroenterology2015，21，37： | 0 |
