Background: Bariatric surgery (BS) is one of the most effective approaches to weight loss. Performing esophagogastroduodenoscopy (EGD) prior to BS is controversial but allows the detection and treatment of mucosal lesions that may affect surgical decision and type of surgery. Aim: The aim of this study was to identify the frequency of gastric lesions and Helicobacter pylori (Hp) infection in a group of asymptom...
Mantle cell lymphoma (MCL) of the colon is a rare entity, usually presenting as lymphomatous polyposis. We report the case of a 43-year-old male with an unusual colonic MCL in the form of a single exophytic and ulcerous lesion with necrotic areas associated with an ileo-cecal intussusception. The endoscopic appearance suggested adenocarcinoma. However, the diagnosis was made by histology and immunohistochemistr...
AIM To evaluate the role of small bowel capsule endoscopy (SBCE) on the reclassification of colonic inflammatory bowel disease type unclassified (IBDU). METHODS We performed a multicenter, retrospective study including patients with IBDU undergoing SBCE, between 2002 and 2014. SBCE studies were reviewed and the inflammatory activity was evaluated by determining the Lewis score (LS). Inflammatory activity was co...
Ulcerative colitis (UC) is a chronic inflammatory bowel disease characterized by periods of remission and periods of relapse. Patients often present with symptoms such as rectal bleeding, diarrhea and weight loss, and may require hospitalization and even colectomy. Long-term complications of UC include decreased quality of life and productivity and an increased risk of colorectal cancer. Mucosal healing (MH) ha...
Background/Aims: Identifying predictors of endoscopic recurrence (ER) has become very important to guide the decision of postoperative strategy. This study aimed to determine the rate of endoscopic recurrence until 12 months after ileocolic resection for Crohn disease (CD) in a cohort and identify its possible predictors. Materials and Methods: We conducted a retrospective single-center study that included pati...
Introduction: Helicobacter pylori eradication has become increasingly difficult as resistances to several antibiotics develop. We aimed to compare Helicobacter pylori eradication rates between triple therapy and sequential therapy in a naive Portuguese population. Material and Methods: Prospective randomized trial including consecutive patients referred for first-line Helicobacter pylori eradication treatment. ...
Small bowel evaluation is a challenging task and has been revolutionized by high-quality contrasted sectional imaging (CT enterography - CTE) and magnetic resonance enterography (MRE) as well as by small bowel capsule endoscopy (SBCE).The decision of which technique to employ during the investigation of small bowel diseases is not always simple or straightforward. Moreover, contraindications may preclude the us...
Since its emergence in 2000, small bowel capsule endoscopy (SBCE) has assumed a pivotal role as an investigation method for small bowel diseases. The PillCam (R) SB2-ex offers 12 h of battery time, 4 more than the previous version (SB2). Rahman et al recently found that the PillCam (R) SB2-ex has a significantly increased completion rate, although without higher diagnostic yield, compared with the SB2. We would...
Background: Small bowel capsule endoscopy represents the initial investigation for obscure gastrointestinal bleeding. Flexible spectral imaging colour enhancement (FICE) is a virtual chromoendoscopy technique designed to enhance mucosal lesions, available in different settings according to light wave-length - FICE1, 2 and 3. Aims: To compare the diagnostic yield of FICE1 and white light during capsule endoscopy...
