First prospective clinical trial of reduced incision bariatric procedures using magnetic liver retraction.

Background: Exposure of the surgical field is an essential component of minimally invasive surgery. Liver retraction is an important element of bariatric procedures because visualization of the stomach and gastroesophageal junction is key. The magnetic surgical system provides a well-tolerated and effective option for adjustable liver retraction without the use of a dedicated port.

Complete pathological response to Imatinib mesylate in an extraintestinal gastrointestinal stromal tumor.

Introduction: Gastrointestinal stromal tumors (GIST) are the most frequent mesenchymal tumors of the digestive tract. Extraintestinal locations (EGIST) have been described showing similar pattern of immunohistochemical markers than GIST. Inhibitors of tyrosine kinases such as Imatinib or Sunitinib are the mainstay treatment in the management of advanced or metastatic GIST.

Changes in iron transporter divalent metal transporter 1 in proximal jejunum after gastric bypass.

Aim: To describe the variation that divalent metal transporter 1 (DMT1) shows in patients after Roux-en-Y gastric bypass (RYGB) surgery.

Methods: Prospective and analytical study of DMT1 level at the brush border of proximal jejunum in patients having undergone RYGB surgery. The mucosa of proximal jejunum forming the gastrojejunal anastomosis was biopsied during surgery and after 6 mo later with an endoscopic biopsy.

Swallowing dysfunction in nonneurologic critically ill patients who require percutaneous dilatational tracheostomy.

Background: The aim of this study was to determine the incidence of swallowing dysfunction in nonneurologic critically ill patients who require percutaneous dilatational tracheostomy (PDT) for prolonged mechanical ventilation (MV) and to compare the duration of the cannulation period and length of stay in the critical care unit (CCU) in patients with and without swallowing dysfunction.

Methods: A total of 40 consecutive patients without neurologic disorders who require PDT for prolonged MV were included. Previous to the tracheostomy decannulation process, an otolaryngologist performed a fiberoptic endoscopic evaluation of swallowing (FEES).
