Gastric duplication cyst: Evaluation by endoscopic ultrasonography and magnetic resonance imaging

Endoscopic ultrasonography (EUS) and magnetic resonance imaging (MRI) are becoming popular methods for examining tumorous lesions along the upper gastrointestinal tract. Though duplication cysts are uncommon. EUS findings from gastric duplication cysts have accumulated and proven very useful for preoperative diagnosis. There have been few reports, however, concerning MRI findings from these cysts. We report herein the case of a 25-year-old man with a gastric duplication cyst. EUS demonstrated a cystic mass adjacent to the fourth layer of the stomach wall. MRI revealed a cyst containing low signalintensity fluid and high signal-intensity fluid separated by levels. In addition to the characteristic findings from preoperative examinations, the unique histological findings from the cyst are also described.

The advantage of primary resection and anastomosis with intraoperative bowel irrigation for obstructing left-sided colorectal carcinoma

AbstractOf a total 712 patients with left-sided colorectal cancer, 79 (11%) required emergency surgery due to severe obstruction by tumors. Of these 79 patients, 55 underwent tumor resection and anastomosis. Primary resection and anastomosis with intraoperative bowel irrigation was performed in 44 patients (primary group), while staged resection and anastomosis was performed in only 11 (staged group). In comparing the two groups, there was no significant difference in the rates of curative resection, being 76% versus 90%. However, the primary group demonstrated significantly lower rates of postoperative wound infection (P<0.001), anastomotic dehiscence (P

0.05), and postoperative mortality, at 2% versus 18% (P<0.05). The cumulative survival curve was also better in the primary group (P<0.05). These favorable results of the primary group were confirmed by analyses which established that no bias of therapeutic backgrounds existed in either of the two groups. Thus, it was concluded that for left-sided obstructing colorectal carcinoma, intraoperative bowel irrigation, followed by primary resection and anastomosis, produces more advantageous results.

A CASE OF MESENTERIC PANNICULITIS OF THE SIGMOID COLON WITH AN ELEVATION OF SERUM CEA LEVEL

We describe herein the case of a 52-year-old man found to have a solitary pulmonary lymphangioma. Computed tomography (CT) scan demonstrated a nodule with homogeneous density and a well-defined border in the lower lobe of the right lung. T2-Weighted magnetic resonance imaging (MRI) revealed a nodule with homogeneously high signal intensity. The tumor was removed by partial resection, and pathologic examination confirmed a diagnosis of primary lymphangioma of the lung.
