Esophageal Adenocarcinoma: Impact of a Large Hiatal Hernia on Outcomes After Surgery.

Objective: To evaluate complete tumor resection rate (primary objective), 30-day postoperative outcomes, and survival (secondary objectives) in patients with a hiatal hernia (HH) ≥5 cm (HH group) compared with those who did not have a HH or presented with a HH <5 cm (control group).

Background: HH is a risk factor for esophageal and junctional adenocarcinoma (EGJA). Its impact on the outcomes after EGJA surgery is unknown.

Lobulated enhancement evaluation in the follow-up of liver metastases treated by stereotactic body radiation therapy.

Objective: The Response Evaluation Criteria in Solid Tumors (RECIST) can have limitations when used to evaluate local treatments for cancer, especially for liver malignancies treated by stereotactic body radiation therapy (SBRT). The aim of this study was to validate the relationship between the occurrence of lobulated enhancement (LE) and local relapse and to evaluate the utility of this relationship for predicting local progression.

Patients And Methods: Imaging data of 59 lesions in 46 patients, including 281 computed tomographic (CT) scans, were retrospectively and blindly reviewed by 3 radiologists.

[New methods for exploration of the small intestine].

For ten years, a lot of advances have been achieved for the morphological exploration of the small intestine as well as with CT and MR enterography than with wireless capsule endoscopy. These investigations have renewed the approaches of different diseases that can affect the small intestine: tumors, especially sub-mucosal tumors (CT enterography), iron-deficiency anemia (capsule endoscopy) and follow-up of patients with Crohn's disease of the small intestine (MR enterography). Balloon enteroscopy may then allow therapeutic approach when needed (treatment of bleeding angiodysplasia).
