RESUMO
A 54-year-old male with a medical history of diabetes mellitus type 2 and tonsil cancer treated with radiochemotherapy years previously was admitted to hospital due to one-month progressive diarrhea, epigastric pain and 14-kg weight loss. Laboratory tests revealed mild anemia (Hb 10.8 g/dl). Upper endoscopy (UE) showed multiple ulcerated lesions with raised edges and a hard consistency on biopsy, being more evident at the duodenum and with a lower frequency and smaller diameter in the stomach.

BACKGROUND & AIMS: After endoscopic mucosal resection (EMR) of colorectal lesions, delayed bleeding is the most common serious complication, but there are no guidelines for its prevention. We aimed to identify risk factors associated with delayed bleeding that required medical attention after discharge until day 15 and develop a scoring system to identify patients at risk. METHODS: We performed a prospective study of 1214 consecutive patients with nonpedunculated colorectal lesions 20 mm or larger treated by EMR (n = 1255) at 23 hospitals in Spain, from February 2013 through February 2015. Patients were examined 15 days after the procedure, and medical data were collected. We used the data to create a delayed bleeding scoring system, and assigned a weight to each risk factor based on the ß parameter from multivariate logistic regression analysis. Patients were classified as being at low, average, or high risk for delayed bleeding. RESULTS: Delayed bleeding occurred in 46 cases (3.7%, 95% confidence interval, 2.7%-4.9%). In multivariate analysis, factors associated with delayed bleeding included age ≥75 years (odds ratio [OR], 2.36; P < .01), American Society of Anesthesiologist classification scores of III or IV (OR, 1.90; P ≤ .05), aspirin use during EMR (OR, 3.16; P < .05), right-sided lesions (OR, 4.86; P < .01), lesion size ≥40 mm (OR, 1.91; P ≤ .05), and a mucosal gap not closed by hemoclips (OR, 3.63; P ≤ .01). We developed a risk scoring system based on these 6 variables that assigned patients to the low-risk (score, 0-3), average-risk (score, 4-7), or high-risk (score, 8-10) categories with a receiver operating characteristic curve of 0.77 (95% confidence interval, 0.70-0.83). In these groups, the probabilities of delayed bleeding were 0.6%, 5.5%, and 40%, respectively. CONCLUSIONS: The risk of delayed bleeding after EMR of large colorectal lesions is 3.7%. We developed a risk scoring system based on 6 factors that determined the risk for delayed bleeding (receiver operating characteristic curve, 0.77). The factors most strongly associated with delayed bleeding were right-sided lesions, aspirin use, and mucosal defects not closed by hemoclips. Patients considered to be high risk (score, 8-10) had a 40% probability of delayed bleeding.

INTRODUCTION: exposure to ionizing radiation is associated with an increased risk of developing tumors. Patients with Crohn's disease (CD) usually require multiple imaging tests using this type of radiation. OBJECTIVES: the objectives of this study were to estimate the total dose of ionizing radiation received by patients with Crohn's disease during their course and to identify the factors associated with higher radiation doses. METHODS: two hundred thirty-five CD patients diagnosed between 1972 and 2010 were included. The effective dose (ED) received by each patient was calculated retrospectively based on the number of gastrointestinal transit studies and computed tomography scans performed. Considering recent epidemiological studies, an ED greater than or equal to 50 mSv was used as the cut-off point for increased risk of developing cancer. RESULTS: the mean ED received per patient was 33.4 mSv (95% CI 29.3-37.5). A total of 49 (20.8%) patients received an ED ≥ 50 mSv. The following factors were identified as independent predictors associated with an ED ≥ 50 mSv: Age older than 40 years, need for surgery, age under 16 years at diagnosis and disease duration over 8 years. CONCLUSIONS: a substantial proportion of patients with Crohn's disease receive high doses of potentially carcinogenic ionizing radiation. Identification of the most susceptible patients to receive high doses of radiation, monitoring of effective doses received and the use of imaging techniques that do not require ionizing radiation (MR enterography, abdominal ultrasound) could contribute in reducing patients' exposure to potentially carcinogenic ionizing radiation.

INTRODUCTION: endoscopic mucosal resection is an accepted technique for the treatment of proximal gastrointestinal tract superficial lesions. OBJECTIVES: to evaluate the efficacy and safety of this procedure in the proximal gastrointestinal tract. MATERIAL AND METHODS: forty one consecutive patients (23 males and 18 females, mean age of 61 ± 11.5 years) were included in our study. Fifty nine resections were performed in these patients in 69 sessions. Lesions treated consisted of elevated lesions with high grade dysplasia in the context of Barrett's esophagus (group A), high grade dysplasia appearing in random biopsies taken during the follow-up of Barrett's esophagus (group B) and superficial gastroduodenal lesions (group C). Snare resection after submucosal injection, band ligator-assisted or cap-assisted mucosal resection were the chosen techniques. RESULTS: we resected 7 elevated lesions with high grade dysplasia in the context of Barrett's esophagus, 6 complete Barrett's esophagus with high grade dysplasia in 16 sequential sessions and 46 gastroduodenal superficial lesions (10 adenomas, 9 gastric superficial carcinomas, 18 carcinoid tumours and 9 lesions of different histological nature). Resections in the two first groups were complete in 100% of the cases, and in 97.9% of the cases in group C. Complications included 2 cases of limited deferred bleeding (groups A and B) and another two cases of stenosis with little clinical relevance in Group B. CONCLUSIONS: a) endoscopic mucosal resection is an efficient technique for the treatment of proximal gastrointestinal tract superficial lesions; b) it is a safe procedure with a low percentage of complications, which can generally be managed endoscopically; and c) in contrast with other ablative techniques, endoscopic mucosal resection offers the possibility of a pathologic analysis of the samples.
