Use of sonography in the evaluation of the gastroesophageal junction

To demonstrate the gastroesophageal junction with a real-time, transabdominal sonography through the window of left lobe of liver, the normal sonographic pattern and the thickness of the wall of abdominal esophagus were determined. The detection rate of the normal pattern in 30 control subjects was 93%, the normal thickness of the wall being 3.8 ± 1.2 mm (range 2 mm to 5 mm). In 7 patients with severe acute esophageal inflammation, the thickness was 7.6 ± 2.1 mm (range 5 mm to 10 mm). In 6 patients with an invading lesion in the gastroesophageal junction due to malignancy, the thickness of the wall was more than 10 mm in each case. This preliminary study indicates that the sonographic detection of gastroesophageal junction through the liver window can be included in routine abdominal sonography. An increased thickness of the wall needs further study to find the cause of the thickening. © 1996 John Wiley & Sons, Inc.     

Extraordinary muscular structure leads to urethral injury after vaginal delivery in animal study

Introduction and hypothesis  

The aim of this study is to explore causality of birth trauma after vaginal delivery and anatomical findings.     

Dieulafoy's lesion of the jejunum.

Dieulafoy's lesion is a rare vascular anomaly but a potentially life-threatening disease. This lesion can also be found in the small intestine, which can be diagnosed only by angiography. However, the angiography may be normal when the bleeding is inactive. We report a case of jejunal Dieulafoy's lesion with a repeated attack of massive gastrointestinal bleeding with a normal initial angiography. The pathological examination found an unusual picture as a dilated submucosal vessel protruded like a submucosal tumor.     

Salmonellosis with liver abscess mimicking hepatocellular carcinoma in a diabetic and cirrhotic patient: a case report and review of the literature.

Salmonellosis with liver abscess in a cirrhotic liver is extremely rare. We report the first case of Salmonellosis with septic shock and liver abscess in a diabetic and cirrhotic patient. The image studies of liver initially favored hepatocellular carcinoma. But no definite focus of sepsis was found. After close follow-up of the liver space-occupied lesion, ultrasound examination revealed the features of liver abscesses at space-occupied lesion later. Ultrasound-guided liver aspiration proved abscess. The clinical and radiological responses were good after antibiotics treatment.     

Angiomyolipoma of the Colon

Angiomyolipoma of the colon is very rare. Only three cases have been reported in the literature. Here we report the case of a 54-year-old male, who presented with a progressive abdominal cramping pain. We performed left hemicolectomy under the impression of a cancerous mass over the splenic flexure of the colon. Histology revealed an angiomyolipoma of the colon. In addition, we review the literature.     

Endosonographic appearances of Brunner's gland hamartomas

Brunner's gland hamartoma is an uncommon intestinal tumor, most frequently located in the duodenal bulb. We report the endoscopic sonographic (EUS) appearances in 2 cases of Brunner's gland hamartoma. In 1 case, EUS revealed a heterogeneous hypoechoic pedunculated mass, 1.7 cm in diameter, arising from the mucosal and submucosal layers of the wall of the duodenal bulb. Multiple anechoic large and small cystic areas were demonstrated in the tumor. In the other case, EUS revealed a 1.4- x 0.9-cm pedunculated mass with an echogenicity higher than that of the muscular layer and lower than that of the mucosa, arising from the submucosal layer of the duodenal bulb wall. Multiple small anechoic areas were demonstrated in the tumor. We believe that both EUS patterns are typical for Brunner's gland hamartomas.
