Intraductal papillary mucinous neoplasm penetrating to the stomach, duodenum, and jejunum demonstrated on MR cholangiopancreatography with an oral negative contrast agent.

A 65-year-old man was referred to our hospital due to epigastric pain. Abdominal enhanced computed tomography (CT) demonstrated marked dilatation of the main pancreatic duct (MPD) and communication to the gastric and duodenal lumen was suspected. Esophagogastroduodenoscopy (EGD) showed a villous tumor with white mucous discharge in the posterior wall of the gastric corpus and duodenal bulb.

Diagnostic accuracy of CT colonography and optical colonoscopy evaluated using surgically resected specimens.

Objective: The aim of this study was to clarify the diagnostic ability of CT colonography (CTC) using surgically resected specimens to avoid inaccuracy associated with optical colonoscopy (OC).

Subjects And Methods: CTC and OC were performed in 152 consecutive patients with colorectal cancer. Forty patients had simultaneous lesions other than the ones for which the surgery was intended, and these lesions were used as the gold standard.

Visceral obesity predicts surgical outcomes after laparoscopic colectomy for sigmoid colon cancer.

Purpose: This study was designed to assess whether visceral obesity is a more useful predictor of surgical outcomes compared with body mass index after laparoscopic colectomy.

Methods: A total of 133 consecutive patients who underwent elective laparoscopic colectomy for sigmoid colon cancer between April 2001 and April 2007 were included. Obesity was defined by visceral fat area > or = 130 cm(2) or body mass index > or = 25 kg/m(2), and the variables were compared for obese and nonobese patients.
