Relationship between continuous use of low-dose enteric-coated aspirin and gastrointestinal injuries in patients with gastrointestinal hemorrhage.

BACKGROUND/AIMS: Gastrointestinal disorders are important side effects of aspirin therapy, even if the low-dose enteric-coated form is administered. The aim of the current study was to present the upper and lower endoscopic features of patients with gastrointestinal hemorrhage using low-dose enteric-coated aspirin. MATERIALS AND METHODS: This prospective study was conducted among 633 consecutive patients with gastrointestinal hemorrhage who admitted to our tertiary referral hospital for endoscopy assessment. Patients were divided into two groups as low-dose aspirin users (n=168) and non-aspirin users (n=495). Aspirin users included those who were taking 80-100 mg of enteric-coated aspirin per day. RESULTS: Ulcer lesions were found in 78 patients in the aspirin user group and in 113 patients in the control group. Prevalence of duodenal ulcer was statistically similar between the two groups; however, gastric ulcer was seen more in the aspirin-user group. The use of low-dose aspirin could strongly predict gastric ulcers in the patients examined by endoscopy (p<0.001). Overall prevalence of peptic ulcer disease in those with confirmed Helicobacter pylori infection was significantly higher than in non-infected ones (p<0.001). The presence of this infection was strongly associated with peptic ulcer disease in the aspirin-user group (p<0.001). Multivariable analysis also demonstrated that the use of aspirin had a main triggering effect on short-term mortality following gastrointestinal endoscopy (p=0.003). CONCLUSIONS: Low-dose enteric-coated aspirin causes significant gastric endoscopic lesions and even predicts mortality due to progression of gastrointestinal disorders.

Long-term quality of life after ileal pouch anal restorative proctocolectomy for ulcerative colitis.

Restorative proctocolectomy with ileal pouch anal anastomosis (IPAA) has evolved as the surgical procedure of choice for ulcerative colitis (UC). The aim of our study was to evaluate the quality of life (QOL) of UC patients who underwent this procedure over 5 years ago. Thirty-nine UC patients who underwent restorative proctocolectomy with IPAA were interviewed by the validated inflammatory bowel disease questionnaire (IBDQ). Each patient was assigned a score, ranging from 32 to 224, in which the highest score indicates the best QOL. QOL for postoperative patients was good in 15 (38.5 %), regular in 23 (59 %), and bad in 1 (2.6 %) patient. QOL was not significantly influenced by age or gender of the patient. The emotional aspect received the highest score in the IBDQ and for each question that was analyzed separately; most of the patients were pleased and thankful with their lives and this question received the highest score. Long-term QOL was good in UC patients who underwent IPAA. This operation should be considered as the first choice since the patients were stable after long-term follow up.

Risk factors for post-ERCP cholangitis in patients with pancreatic cancer from a single referral center in Iran.

Cholangitis is relatively uncommon but associated mortality is high due to the predisposition in people with underlying disease. For this recognition of contributing risk factors is necessary. Therefore, the present descriptive- analytical cross-sectional survey was designed to determine contributing risk factors for post-ERCP cholangitis in patients with pancreatic cancer. From 2005 to 2010, 110 consecutive cases of pancreatic cancer attending to a tertiary referral centre (Taleghani Hospital), Tehran, Iran were recruited. The patients all underwent stenting via endoscopic retrograde cholangiopancreatography (ERCP). On univariate analysis, a metallic stent type (95% confidence interval (CI) 1.025-11.34, P=0.037), having no jaundice (1.44-2.22, P=0.009), having no pain (1.32-1.91, P=0.026), a history of prior ERCP (1.16-10.37, P=0.020), and having a proximal biliary stone (1.002- 5.93, P=0.046) were related to cholangitis. However on multivariate analysis, none of these factors were found to be contributing risk factors. Cholangitis is avoidable with adequate biliary drainage. Because success rates are higher and complication rates lower for endoscopists performing large volumes of ERCP, performance of the procedure should be concentrated as much as possible in institutions with endoscopists having adequate experience. Patients with a high risk for complications may be best served by referral to an advanced center.

Botulinum toxin injection versus lateral internal sphincterotomy for the treatment of chronic anal fissure: randomized prospective controlled trial.

PURPOSE: Lateral internal sphincterotomy has been the gold standard treatment for chronic anal fissure, but it still carries the risk of permanent damage of the anal sphincter, which has led to the implementation of alternative treatment like botulinum toxin injection. The aim of this randomized prospective controlled trial was to compare the efficacy and morbidity of botulinum toxin injection and lateral internal sphincterotomy in the treatment of chronic anal fissure. METHODS: Fifty consecutive adults with chronic anal fissure were randomly treated with either lateral internal sphincterotomy or botulinum toxin (BT) injection with 50 U BT into the internal sphincter. The complications, healing and recurrence rate, and incontinence score were assessed 2, 3, 6, 12 months after the procedure. RESULTS: Inspection at the 2-month visit revealed complete healing of the fissure in 11 (44 %) of the patients in the BT group and 22 (88 %) of the patients in the lateral internal sphincterotomy (LIS) group (p = 0.001). At the 3-month visit, there was no significant difference between the two groups in healing. The overall recurrence rate after 6 months in the BT group was higher than in the LIS group (p < 0.05). In the 3-month follow-up, the LIS group had a higher rate of anal incontinence compared to the BT group (p < 0.05). The final percentage of incontinence was 4 % in the LIS group (p > 0.05). CONCLUSIONS: The treatment of chronic anal fissure must be individualized depending on the different clinical profiles of patients. Botulinum toxin injection has a higher recurrence rate than LIS, and LIS provides rapid and permanent recovery. However, LIS carries a higher risk of anal incontinence in patients.
