A Martín Díaz, L Fernández Rodríguez, M Martí de Gracia
Acute lower gastrointestinal bleeding usually presents as hematochezia, rectal bleeding or melena and represents 1-2% of the medical appointments in the Emergency Services. Mortality reaches the 30-40% and it is highly related with the severity and associated comorbidity. Most clinical practice guidelines include colonoscopy at some point in the diagnostic and therapeutic process (urgent for severe cases and ambulatory for mild ones) and look for predictors of severity. In the last years, there have been numerous studies where is clear the relevance and complementarity of advanced diagnostic imaging techniques, gradually incorporated as an alternative or second step in severe cases...

Haemobilia is a rare cause of upper gastrointestinal bleeding that consists of haemorrhage within the biliary tree. Most cases of haemobilia are due to iatrogenic cause, laparoscopic or open cholecystectomy, abdominal trauma, gallstones, hepatic tumours, vascular aneurism. We present the case of a male patient admitted in the surgery department for epigastric and right hypochondria pain, nausea and vomiting. Open cholecystectomy was performed with a trans-cystic tube drainage. Postoperative outcome was favourable but with a continuous decrease in haemoglobin level...

PURPOSE: WHO GLOBOCAN 2012 data showed that Australia and New Zealand have the highest incidence rates of colorectal cancer in the world (Ferlay et al. 1). Current guidelines recommend that patients admitted for an episode of acute diverticulitis require an early follow-up colonoscopy to rule out colorectal malignancy as reported by Fozard et al. (Colorectal Dis 13:1-11, 2011). Recent studies however have indicated that this may not be warranted (Brar et al. Dis Colon rectum 56:1259-1264, 2013)...

Among the various manifestations of colonic involvement in malignant lymphomas, an ulcerative colitis-like appearance is rare. Herein, we describe a case in which extranodal colonic involvement resembled ulcerative colitis in a patient with advanced follicular lymphoma. A 59-year-old Japanese man with diarrhea and body weight loss was referred to our hospital. Computed tomography (CT) revealed systemic lymphadenopathy, splenomegaly, and thickening of the sigmoid colon and rectum walls. (18)F-fluorodeoxy-glucose positron emission tomography ((18)F-FDG-PET/CT) revealed intense tubular (18)F-FDG accumulation extending from the rectum to the colon at the hepatic flexure and much weaker accumulation in the systemic lymph nodes, bone marrow, and spleen...

BACKGROUND: The aim of treatment of patients with colovesical fistulas should be prompt elimination of the infection and the social burden. We focused on the question whether a minimally invasive surgical approach as a cooperation between surgeons and urologists is possible. This requires effective diagnostics prior to the operation. METHODS: Since 2007 a total of 32 patients with the clinical suspicion of colovesical fistula have undergone extensive preoperative diagnostics...

BACKGROUND: Approximately 2.1% to 8.6% of all pregnancies after IVF with embryo transfer have been reported to be ectopic. In this report, we present a case of presumed intestinal microperforation caused by an ectopic pregnancy following IVF. CASE: A 29-year-old woman presented with rectal bleeding. She had previously been treated for an ectopic pregnancy for which she had received two doses of methotrexate. Colonoscopy and abdominal CT angiography were performed and showed that the ectopic pregnancy was attached to the sigmoid colon...

BACKGROUND AND AIMS: Most international guidelines recommend performing a routine colonoscopy after the conservative management of acute diverticulitis, mainly to rule out a colorectal malignancy; however, data to support these recommendations are scarce and conflicting. This study is aimed at determining the rate of advanced colonic neoplasia (ACN) found by colonoscopy, and hence the need for routine colonoscopy after CT-diagnosed acute diverticulitis. METHODS: We retrospectively analyzed all patients hospitalized for acute diverticulitis between July 2008 and June 2013...

BACKGROUND: As the clinical use of fluorine-18-fluorodeoxyglucose PET-computed tomography (F-FDG PET-CT) has increased, the incidental finding of F-FDG uptake with subsequent diagnosis of advanced neoplasm at colorectum has increased. The aim of this study is to analyze the characteristics and risk factors of advanced colorectal neoplasm incidentally detected by F-FDG PET-CT. PATIENTS AND METHODS: Patients who underwent colonoscopy because of an incidental finding of F-FDG uptake at the colorectum from January 2006 to January 2015 at Yeungnam University Hospital were reviewed retrospectively...

The incidental detection of a tubulovillous adenoma at a contrast-enhanced computed tomography (CECT) with nondedicated protocol, performed in emergency conditions, is an uncommon finding. We report a case of a woman presenting with a subocclusive episode. A CECT scan was performed, and a pedunculated polyp could be appreciated at 3D-reconstruction images. A particular depiction of pedunculus of the polypoid lesion, resemble a clapper-bell, could help to define the vegetating lesion at the volume-rendering reconstruction images...

Multiple lymphomatous polyposis (MLP) as an extranodal manifestation of mantle cell lymphoma (MCL) in the gastrointestinal tract is rare and not often reported in the literature. We describe the case of a 63-year-old female with asymptomatic MLP found during staging bidirectional endoscopy of MCL. The patient presented only with dyspnea, but was found on physical exam to have diffuse lymphadenopathy, and subsequent positron emission tomography (PET) CT showed extensive lymph node adenopathy consistent with lymphoma...

Primary colonic adenocarcinoma and synchronous rectal carcinoids are rare tumors. Whenever a synchronous tumor with a nonmetastatic carcinoid component is encountered, its prognosis is determined by the associate malignancy. The discovery of an asymptomatic gastrointestinal carcinoid during the operative treatment of another malignancy will usually only require resection without additional treatment and will have little effect on the prognosis of the individual. This article reports a synchronous rectal carcinoid in a patient with hepatic flexure adenocarcinoma...

Saad Nadeem, Joseph Marino, Xianfeng Gu, Arie Kaufman
We present a method for registration and visualization of corresponding supine and prone virtual colonoscopy scans based on eigenfunction analysis and fold modeling. In virtual colonoscopy, CT scans are acquired with the patient in two positions, and their registration is desirable so that physicians can corroborate findings between scans. Our algorithm performs this registration efficiently through the use of Fiedler vector representation (the second eigenfunction of the Laplace-Beltrami operator). This representation is employed to first perform global registration of the two colon positions...

PURPOSE: To examine factors influencing primary care provider (PCP) adoption of CT colonography (CTC) for colorectal cancer (CRC) screening. MATERIALS AND METHODS: We performed a retrospective cohort study linking electronic health record (EHR) data with PCP survey data. Patients were eligible for inclusion if they were not up-to-date with CRC screening and if they had CTC insurance coverage in the year prior to survey administration. PCPs were included if they had at least one eligible patient in their panel and completed the survey (final sample N = 95 PCPs; N = 6245 patients)...

Adenocarcinoma arising in an ileal diverticulum are very rare. A 66-year-old man was recognized to have high serum CEA level and periappendiceal polycystic tumor in CT findings. Colonoscopy showed no abnormality in the ileocecal mucosa. However, the patient was suspected of appendiceal adenocarcinoma by PET/CT, which revealed FDG uptake with SUVmax of 3.9 in the tumor, and underwent radial surgery by single-incision laparoscopic surgery. Intraoperative findings showed the mass in the mesenterium of the terminal ileum but not the abnormality of the appendix...

PURPOSE: The human colon has complex geometric structures because of its haustral folds, which are thin flat protrusions on the colon wall. The haustral loop is the curve (approximately triangular in shape) that encircles the highly convex region of the haustral fold, and is regarded as the natural landmark of the colon, intersecting the longitude of the colon in the middle. Haustral loop extraction can assist in reducing the structural complexity of the colon, and the loops can also serve as anatomic markers for computed tomographic colonography (CTC)...

A 78-year-old woman who had recurrent right lower abdominal pain for about 1 year underwent computed tomography (CT) because of a follow-up observation 1 year after right breast cancer surgery. CT revealed a tumor in the colon. The patient was referred to our hospital for detailed examinations. An abdominal CT showed a low-density tumor of approximately 30 mm in the ascending colon, and the CT density inside the tumor was same as that of fatty tissues. A subsequent colonoscopy showed a submucosal tumor (SMT) in the proximal ascending colon developing from the terminal ileum...

BACKGROUND: Colonoscopy is currently the gold standard for detection of colorectal lesions, but may be limited in anatomically localising lesions. This audit aimed to determine the accuracy of colonoscopy lesion localisation, any subsequent changes in surgical management and any potentially influencing factors. METHODS: Patients undergoing colonoscopy prior to elective curative surgery for colorectal lesion/s were included from 8 registered U.K. sites (2012-2014)...

OBJECTIVE: Increased focal colorectal uptake of fluorine-18-fluorodeoxyglucose ((18)F-FDG) is reported to occur in 1%-3% of patients undergoing (18)F-FDG positron emission tomography/computed tomography (PET/CT) for disease outside the bowel. However, there is no consensus on how to deal with this finding in the clinic. Due to the non-specific appearance of such lesions and a certain rate of false positive findings, patients may by subjected to unnecessary invasive procedures or, conversely, cancers may be overlooked if the risk of malignancy is downplayed...
