Optimal use of oral nutritional supplements (ONS) in medical nutrition therapy: ONS consensus report from KEPAN.

Medical nutrition therapy is one of the core components of the patient management, although its implication is still limited in daily practice globally. Clinicians are in need of guidance that will ease the application of medical nutrition therapy. The first treatment choice in medical nutrition therapy is the use of oral nutritional supplements (ONS) after or concomitant with dietary interventions.

Multidetector computed tomography diagnosis of adenomyomatosis of the gallbladder.

The differentiation of gallbladder adenomyomatosis from gallbladder carcinoma is important as both conditions may present with thickening of the gallbladder wall or as a focal mass. Identification of Rokitansky-Aschoff sinuses is the key feature in making an accurate diagnosis of gallbladder adenomyomatosis on imaging studies. The diagnosis of gallbladder adenomyomatosis can be made with accurately by multidetector computed tomography when the presence of Rokitansky-Aschoff sinuses (small cystic spaces within the thickened gallbladder wall) are noted.

Surgical outcome of patients with perforation after endoscopic retrograde cholangiopancreatography.

Background: The most important criterion in the management of endoscopic retrograde cholangiopancreatography (ERCP)-related perforations is the delineation of the injury pattern. The aim of the present study was to evaluate in a retrospective manner the patients who undergo surgery due to ERCP-related perforations.

Methodology: Peritoneal lavage samples were obtained from 255 patients who underwent radical gastrectomy with D2 (184 patients) or D3 (71 patients) lymph node dissection between January 2000 and December 2007.

Results: Thirty-six (14.

Management of choledochal cysts in adults: a retrospective analysis of 23 patients.

Background/aims: Choledochal cysts are rare congenital anomalies of the pancreaticobiliary system, whose etiology remains unknown. We aimed to review patients with choledochal cysts and to compare our results with current literature.

Basic hemostatic parameters in patients with long-term oral anticoagulation undergoing cholecystectomy.

Background: The current hemostatic data in relation to laparoscopic cholecystectomy (LC) is limited particularly for patients receiving chronic oral anticoagulant treatment. The aim of this study is to assess hemostatic alterations before, during and after LC for the patients placed on long-term oral anticoagulant treatment.

Patients And Methods: A prospective, nonrandomized, controlled study was designed to compare the characteristics, hemostatic system, and postoperative complications of patients maintained on long-term anticoagulation with those who did not receive such therapy.
