ABSTRACT
INTRODUCTION: Duplication of the alimentary tract is a relatively rare congenital anomaly. It can affect any part of the gastrointestinal tract, with ileum being the most common site. These malformations are believed to be congenital, formed before the differentiation of epithelial lining, and therefore named for the organ with which they are associated. Duplication cysts of the stomach represent four percent of all alimentary tract duplications. CASE REPORT: Here, we report a rare case of symptomatic duplication cyst of stomach associated with ectopic pancreas presenting in adult. DISCUSSION: Gastrointestinal duplication is a relatively rare anomaly that may occur at any level from oral cavity to rectum with ileum being the most common site. Duplication cysts of the stomach are quite rare, and most of them have been reported in children. Duplication cysts of ileum are usually located on the mesenteric border, whereas the usual location for gastric duplication cysts is along the greater curvature. The duplication cyst is entirely separated from the adjacent bowel but shares a common wall. Complete removal is the treatment choice to avoid the risk of possible complications such as obstruction, torsion, perforation, hemorrhage, and malignancy. A non-communicating GDC is classically treated by complete excision of the cyst and resection of the shared wall between stomach and the duplication cyst. CONCLUSION: This unusual developmental anomaly should be included in the differential diagnosis of cystic masses of the gastrointestinal tract, and the possibility of malignancy should also be considered, so as be treated surgically by complete resection.
ABSTRACT
Pancreatic neoplasms are well-known pathological entities with generally poor prognosis. Mesenchymal tumors comprise 1 to 2% of all pancreatic tumors, and lipomas are a very rare variant of them. There are benign mesenchymal tumors consisting of mature adipose cells and thin collagen capsule. Most of the cases are generally published as sporadic case reports. The present review aims to elucidate the morphological entity named pancreatic lipoma, which is nearly unknown to most of surgeons. We estimate that pancreatic lipomas may be more common than previously realized, as small incidental lipomas may not have been reported in the literature to date.

BACKGROUND/AIMS: The hemodynamic disturbances in the cirrhotic liver following severe variceal bleeding and subsequent restoration by blood transfusion is an ischemia/reperfusion injury event which represents the clinical situation of liver dysfunction. Therefore, the aim of this study was to evaluate the microcirculation, oxygenation and energy charge of the cirrhotic rat liver after ischemia/reperfusion. METHODOLOGY: In eight carbon tetrachloride-induced cirrhotic rats and an equal number of controls subjected to 30 minutes of ischemia and 60 minutes of reperfusion by hepatoduodenal ligament clamping, the following parameters were assessed: hepatic microcirculation by laser-Doppler fluxmetry, hepatic tissue oxygenation by a Clark-type electrode, hepatic energy charge by tissue sampling and adenine-nucleotides determination by means of high-performance liquid chromatography. RESULTS: At baseline, liver microcirculation was found to be significantly decreased in the cirrhotics versus controls groups. Ischemia led to a reduction in both groups, while reperfusion improved microcirculation, but not to the baseline level. Oxygenation was reduced during ischemia and restored after reperfusion in both groups. Hepatic energy charge was reduced in the cirrhotics versus controls at baseline, and significantly decreased during ischemia in both groups. At reperfusion, a further reduction was found in the cirrhotic group, while in the control group it was restored to baseline. CONCLUSION: Hepatic microcirculation, oxygenation and energy charge are subjected to different degrees of diminution after ischemia/reperfusion in the cirrhotic rat liver.
