BACKGROUND & AIMS: A previous UK study showed that 6.1% of patients with diarrhea-predominant IBS (IBS-D) had evidence of severe pancreatic exocrine insufficiency (PEI), but these findings need replication. We aimed to identify the prevalence of PEl based on faecal elastase stool testing in consecutive outpatients presenting with chronic unexplained abdominal pain and/or diarrhea and/or IBS-D. METHODS: Patients aged over 40 years presenting to hospital outpatient clinics from 6 sites within Australia with unexplained abdominal pain and/or diarrhea for at least 3 months and/or IBS-D were studied...

We report the case of a 47-year old Caucasian man with a history of depression and high alcohol intake who presented with a one-month history of weight loss, dry cough and abdominal pain. He had no smoking history of note. The patient was treated for a suspected chest infection, however developed respiratory failure and was intubated. A CT showed multiple pulmonary nodules, left pleural thickening extending to the mediastinum and bilateral pleural effusions-larger on the left, suggestive of disseminated malignancy...

Identifying the etiology of chronic diarrhoea might be challenging in some patients, and before a diagnosis is made these patients may spend a substantial length of time with unresolved symptoms leading to uncertainty and anxiety that is severely impairing their life quality. A 45-year-old female was referred by her general practitioner with a 5-year history of increasingly frequent episodes of cyclical diarrhoea, vomiting, abdominal pain and intermittent palpitations. Contrast CT Abdomen/Pelvis revealed a 36x33x46 mm mass in the aorto caval region of her retro-peritoneum, just above the bifurcation...

A woman in her 30s was admitted with abdominal pain and nausea. CT scan revealed a spontaneous rupture of the right giant renal angiomyolipoma, and trans-arterial embolization was performed successfully. With further examination, she was found to be affected with tuberous sclerosis complex (TSC) and she finally wastreated with everolimusfor prevention of recurrent spontaneous-rupture of renal angiomyolipoma.

PURPOSE: Kilt technique can be useful for overcoming the severe angle in endovascular abdominal aortic repair. Thus, we investigate the utility of the Kilt technique as an angle modification method. METHODS: This study included 16 patients with abdominal aortic aneurysm having severe neck angle (over 60°). Of these, eight were treated using Kilt technique, whereas the remaining eight were by the conventional endovascular method. We investigated the pre- and post-procedural differences in neck angle between the two groups using aortic computed tomography (CT) angiography...

A 54-year-old woman presented to our centre with acute abdominal pain and vomiting. Routine blood tests showed severe hypercalcaemia (>4 mmol/L). Serum parathyroid hormone (PTH) was suppressed. CT scan detected a pancreatic mass and some liver lesions, initially suspicious for metastatic pancreatic adenocarcinoma. Liver biopsy however revealed the presence of a well-differentiated, grade 1, metastatic neuroendocrine tumour (NET) where prognosis is considerably better. Serum PTHrP was raised, indicating paraneoplastic hypercalcaemia, most likely secondary to the pancreatic NET...

BACKGROUND: Gastric leak (GL) is one of the main early-onset postoperative complications of sleeve gastrectomy (SG). Many institutions perform routine upper gastrointestinal (UGI) contrast studies within 24 hours of surgery, looking for GL or gastric stenosis and to determine the need for urgent re-exploration, but this examination delays oral feeding, can cause side effects and is responsible for systematic and probably unnecessary irradiation of the patient. OBJECTIVE: Determine the efficacy of routine UGI contrast studies to predict postoperative complications after SG in a large population...

BACKGROUND: The metastases of a primary lung cancer over the thyroid gland are extremely rare. We report on an unusual presentation of thyroid metastasis of lung cancer in order to improve the management of similar cases. CASE PRESENTATION: Three years ago, a Moroccan male 59-year-old was admitted for dyspnea, dry cough, and chest pain. He had smoked about 30 cigarette packs a year. Clinical examination revealed a right thyroid nodule. Chest and neck computed tomography (CT) scan showed a proximal left tumor in contact with the pulmonary artery and revealed a suspected nodule in the right lobe of the thyroid with homolateral neck node...

OBJECTIVE: To demonstrate the clinical applicability of 3-dimensional CT angiography (3D-CTA) in evaluating the anatomic variations of inferior mesenteric artery (IMA) and left colic artery (LCA), to help make pre-operative strategies of rectal cancer surgery. METHODS: 188 patients with abdominal and pelvic contrast-enhanced CT scan were retrospectively enrolled and 3D-CTA was reconstructed. The origin and branching patterns of IMA, tracking patterns of LCA, intersectional patterns among IMA, LCA and inferior mesenteric vein (IMV) were examined, and their associations with clinical features were analyzed...

Three-dimensional (3D) printing, combined with medical imaging technologies, such as computed tomography (CT) and magnetic resonance imaging (MRI), has shown great potential in patient-specific tissue regeneration. Here, we successfully fabricated an ultrathin tubular freeform structure that has a wall thickness of several tens of micrometers and is capable of providing sufficient mechanical flexibility. Such a thin geometry cannot easily be achieved by 3D printing alone; therefore, it was realized through a serial combination of processes that included the 3D printing of a sacrificial template, the dip-coating of the biomaterial, and the removal of the inner template...

A 43-year-old otherwise healthy woman was found to have a retroperitoneal mass during a routine medical examination and was referred for further evaluation. Abdominal CT scan showed a well-delineated, low-density area that exhibited heterogeneous contrast enhancement. The area measured about 20 mm in size and was to the left of the aorta at the level of the inferior mesenteric artery. MRI showed a mass with heterogeneous hypointensity on T1 -weighted images and heterogeneous hyperintensity on T2 -weighted images...

Zollinger-Ellison syndrome (ZES) is a rare clinical disorder, characterized by hypersecretion of gastric acid and multiple ulcers distal to the duodenal bulb. This occurs via the release of gastrin by neuroendocrine tumors known as gastrinomas. Patients with ZES present with nonspecific GI symptoms, which often leads to a delay in diagnosis. Our patient is a 55-year-old female with chronic abdominal pain, nausea, and diarrhea. She underwent EGD, EUS, MRCP, CT scans, and cholecystectomy, which did not reveal the cause of her symptoms...

A 55-year-old man was transported to our hospital after a sudden onset of left lower abdominal pain while driving. Computed tomography (CT) of the abdominal region revealed an extensive iso-intense signal region that had a maximum area of 14×15 cm, which we treated conservatively. A series of follow-up CT images showed the gradual decrease of the left peritoneal mass, while continuity with the left adrenal gland became apparent. He was diagnosed with idiopathic adrenal hemorrhage. Adrenal hemorrhage presenting with huge retroperitoneal tumors is rare, and most cases are treated surgically...

We present a case in which the accidental ingestion of a toothpick caused duodenal perforation and small intestinal obstruction. A 58-year-old man visited our emergency room with acute abdominal pain. Computed tomography (CT) showed obstructive ileus as well as a foreign body penetrating the duodenum, which was identified as a toothpick and removed endoscopically. Unenhanced CT was superior in detecting the object. The patient has been doing well since the operation.
