Staple Line Intrathoracic Migration After Sleeve Gastrectomy: Correlation between Symptoms, CT Three-Dimensional Stomach Analysis, and 24-h pH Monitoring.

Purpose: Migration of the staple line is the definition of sliding hiatus hernia in sleeve gastrectomy patients. The main aim was to determine the frequency and measurement of intrathoracic staple line migration and its correlation with GERD symptoms and pH monitoring.

Materials And Methods: This was a prospective clinical trial including all patients who underwent sleeve gastrectomy more than 1 year previously.

Low phospholipid-associated cholelithiasis syndrome: A rare cause of acute pancreatitis that should not be neglected.

Background: Low phospholipid-associated cholelithiasis (LPAC) syndrome is a very particular form of biliary lithiasis with no excess of cholesterol secretion into bile, but a decrease in phosphatidylcholine secretion, which is responsible for stones forming not only in the gallbladder, but also in the liver. LPAC syndrome may be underreported due to a lack of testing resulting from insufficient awareness among clinicians.

Aim: To describe the clinical and radiological characteristics of patients with LPAC syndrome to better identify and diagnose the disease.

Contribution of Computed Tomographic Imaging to the Management of Acute Abdominal Pain after Gastric Bypass: Correlation Between Radiological and Surgical Findings.

Background: We evaluated the diagnostic accuracy of first interpretations of computed tomographic (CT) images and blind interpretation using predefined CT signs in patients with previous Roux-en-Y gastric bypass (RYGBP) and acute abdominal pain.

Methods: We performed a retrospective chart review of patients with RYGBP who underwent surgical exploration from January 2009 to December 2014 for acute abdominal pain in our university institution, excluding patients without CT scan and comparing initial CT imaging interpretation with surgical findings. Two blinded radiologist specialists in bariatric imaging evaluated the CT images for seven previously reported CT signs.

[CT anatomy of the normal spleen: variants and pitfalls].

Normally, the spleen is located in the left hypochondrium. It is attached by the gastrosplenic and splenorenal ligaments. Its tissue composition made up of red pulp and white pulp explains the heterogenous aspect when contrast medium is injected in the arterial phase.

[Incisional subcutaneous endometrioma of the abdominal wall: report of two cases].

Endometriosis occurs in up to 15% of menstruating women. Abdominal wall involvement is rare and always secondary to an invasive procedure. The authors report the imaging and clinical findings of two patients with subcutaneous endometrioma following cesarean section.

[Primary retroperitoneal tumors in adults].

Primary retroperitoneal tumors are rare and most of the time malignant. Because of the large space in which they grow, they are often discovered lately as they are large. CT and MR are the imaging techniques of choice for the primary diagnosis and the follow up of these tumors.

Upper limb vein anatomy before hemodialysis fistula creation: cross-sectional anatomy using MR venography.

Preoperative imaging is indicated to discriminate patent, adequate superficial veins of the upper limbs undetectable by clinical inspection that could be anastomosed for the creation of a durable and functional hemodialysis fistula. The aim of this pictorial review is to provide a venous anatomic map of the upper limbs using MR venography (MRV) which could help surgeons before creation of hemodialysis access fistulas (AVF). At the level of the forearm, the antebrachial cephalic vein is the most commonly identified as patent.

[IVU: a test of the past without future?].

IVU has been gradually replaced over recent years as the "gold standard" investigation for the renal parenchyma and urinary tract by two new modalities: ultrasound and computed tomography. Some authors still advocate IVU for the assessment of renal colic, for the following reasons: the excess cost of CT (which is not true for plain CT) and the absence of functional data (there are specific CT signs for increased pressure). However, the advantages of CT are clearly established: contrast resolution allowing the detection of almost all stones except for certain complications of triple combination therapy in HIV seropositive patients, extensive cover facilitating identification of differential diagnoses, rapidity and greater efficacy, and finally the absence of risk related to the injection of iodinated contrast agents in this indication.

Effect of contrast dilution on contrast-enhanced MR angiography of the aorta and renal arteries.

The aim of this study was to investigate the effect of gadolinium chelate dilution on vascular enhancement in contrast-enhanced two-dimensional (2D) MR subtraction angiography of aorta and renal arteries. Twenty patients were prospectively included. 2D subtraction MR angiography consisted of successive multisection breathhold GRE acquisitions of 16 s (2D FLASH, TR/TE 72/4, flip angle 60 degrees) obtained in the coronal plane before and after intravenous bolus administration of 0.
