The atrial morphology and venous connections were assessed "blind" in 51 necropsy specimens from patients with visceral heterotaxy. This was compared with bronchial morphology as established by dissection. Six specimens were found to have both atria and bronchi in situs solitus or inversus, and were rejected. In the remainder, atrial isomerism was diagnosed, though this required minor revision ...

Situs inversus totalis is is a congenital anomaly associated with various visceral abnormalities, but there is no data about the relationship between secondary biliary cirrhosis and that condition. We here present a case of a 58 year-old female with situs inversus totalis who was admitted to our clinic with extrahepatic cholestasis. After excluding all potential causes of biliary cirrhosis, sec...

KNOWLEDGE of the position of the abdominal organs is important in cardiac diagnosis. Thus a mirror-image dextrocardia is usually observed in a patient with complete situs inversus; this condition more frequently occurs in an otherwise normal individual than in one with a malformed heart. By contrast, when dextrocardia occurs without situs inversus, malformation of the heart is the rule. When th...

INTRODUCTION Mucinous adenocarcinoma is a rare neoplasm of the gastrointestinal tract and one of the three major histological subtypes of the primary appendiceal adenocarcinoma. The most common type of presentation is that of acute appendicitis and the diagnosis is usually occurred after appendectomy. The accurate preoperative diagnosis and management of the above condition represents a real ch...

BACKGROUND Situs inversus totalis is a rare autosomal disorder in which the patient's affected visceral organs are a perfect mirror image of their normal positions. Surgery in these patients is technically challenging. Minimally invasive surgery such as laparoscopic cholecystectomy is the standard treatment for symptomatic cholelithiasis, but it can be difficult to perform. Laparoscopic cholecy...

Situs inversus totalis is a rare congenital anomaly characterized by the mirror-image position of abdominal and thoracic organs, heart compared to their normal anatomical position. The estimated prevalence situs in general population ranges from 1:6500 1:25000. can be associated with primary ciliary dyskinesia, structural abnormalities heart, anomalies visceral clinical picture depends on anoma...

Determination of the left-right position (situs) of visceral organs involves lefty, nodal and Pitx2 genes that are specifically expressed on the left side of the embryo. We demonstrate that the expression of these genes is prevented by the addition of a retinoic acid receptor pan-antagonist to cultured headfold stage mouse embryos, whereas addition of excess retinoic acid leads to their symmetr...

We report a case of far-advanced hepatocellular carcinoma (HCC) with situs ambiguous, complex visceral and vascular anomalies, who was successfully managed by extended hemi-hepatectomy. A 67-year-old man was referred to our hospital with a large liver mass. Abdominal ultrasonography, computed tomography and angiography revealed HCC with a diameter of 10 cm, with tumor thrombus in the main and f...

This is a morphologic study of 41 cases of dextrocardia for the purpose of clarifying terminology and evaluating the clinical import of the morphologic data. Dextrocardias are classified as dextroversion, mirror-image dextrocardia, and mixed dextrocardia. When the atrial septum does not identifv the atria, it was found possible to make the presumptive diagnosis of dextroversion or mirror-image ...
