A 16-year-old Chinese male patient presented with constipation lasting five days, colicky abdominal pain, lethargy, weakness and body aches. He was able to pass flatus. Abdominal radiography showed a distended stomach causing inferior displacement of the transverse colon. Computed tomography revealed a dilated oesophagus, stomach and duodenum up to its third portion, with a short aortomesenteric distance and narrow angle. There was also consolidation in the lungs bilaterally. Based on the constellation of clinical and imaging findings, a diagnosis of superior mesenteric artery syndrome complicated by aspiration pneumonia was made. The patient was subsequently started on intravenous hydration, nasogastric tube aspiration and antibiotics. Following stabilisation of his acute condition, a nasojejunal feeding tube was inserted and a feeding plan was implemented to promote weight gain. The clinical presentation, differentials, diagnosis and treatment of superior mesenteric artery syndrome are discussed.

This pictorial review aims to illustrate the magnetic resonance imaging (MRI) findings and presentation patterns of anatomical variations and various benign and malignant pathologies of the duodenum, including sphincter contraction, major papilla variation, prominent papilla, diverticulum, annular pancreas, duplication cysts, choledochocele, duodenal wall thickening secondary to acute pancreatitis, postbulbar stenosis, celiac disease, fistula, choledochoduodenostomy, external compression, polyps, Peutz-Jeghers syndrome, ampullary carcinoma and adenocarcinoma. MRI is a useful imaging tool for demonstrating duodenal pathology and its anatomic relationships with adjacent organs, which is critical for establishing correct diagnosis and planning appropriate treatment, especially for surgery.

A 63-year-old man was found in the street after overrun by a car. Postmortem CT revealed multiple bone fractures, but surprisingly all without any relevant hemorrhage which would have been expected under such circumstances. A round radiopaque formation was found in the duodenum, which was reminiscent of ingested tablets. The toxicological analysis revealed high concentrations of zopiclone and alcohol. By combining radiologic and forensic results, zopiclone and alcohol intoxication were concluded as the cause of death, followed by a postmortem overrun accident.

Brunnera's gland hyperplasia is a benign tumor of the duodenum and it is rarely associated with clinical symptoms. We report on a 64-yr-old man with Brunnera's gland hyperplasia who had undergone a duodenocephalo-pancreatectomy. The reason is that he presented upper gastrointestinal obstructive symptoms and the esophagogastroduodenoscopic finding revealed the lesion to be an infiltrating type mass on the second portion of the duodenum with luminal narrowing. An abdominal computed tomography showed a 2.5 cm-sized mass in the duodenal second portion with a suspicious pancreatic invasion and 7 mm-sized lymph node around the duodenum. Duodenocephalopancreatectomy was successfully performed. Histological examination revealed a Brunnera's gland hyperplasia. The final diagnosis was the coexistence of Brunnera's gland hyperplasia and pancreatic heterotopia with a pancreatic head invasion. The literature on Brunnera's gland hyperplasia is reviewed.

A gastrointestinal metastasis from lung cancer is rare and is quite often found during an autopsy. A 58-year-old man was admitted with left upper back pain and a mass in the left upper lobe on the chest radiograph. The transbronchial lung biopsy revealed an adenocarcinoma of the lung. A gastroduodenoscopy was carried out to evaluate the indigestion and epigastric discomfort. The duodenofibroscopy revealed bulging mucosa on the minor papilla of the duodenum. A metastasis to the duodenum from an adenocarcinoma of the lung was diagnosed by a duodenofibroscopic biopsy of the bulging lesion. We report this rare case of an adenocarcinoma of lung with a metastasis to the duodenum.

OBJECTIVE: To evaluate the usefulness of newly designed sheaths for gastroduodenal intervention in a gastric phantom and dogs. MATERIALS AND METHODS: A regular sheath was made using a polytetrafluoroethylene tube (4 mm in diameter, 90 cm long) with a bent tip (4 cm long, 100 degree angle). For the supported type of sheath, a 5 Fr catheter was attached to a regular sheath to act as a side lumen. To evaluate their supportability, we measured the distance of movement of the sheath's tip within a silicone gastric phantom for three types of sheath, the regular type, supported type, and supported type with a supporting guide wire. The experiments were repeated 30 times, and the results were analyzed using ANOVA with the postHoc test. In addition, an animal experiment was performed in six mongrel dogs (total: 12 sessions) to evaluate the torque and supportability of the sheaths in the stomach, while pushing a guide wire or coil catheter under fluoroscopic guidance. RESULTS: In the guide wire application, the distances of movement of the sheath tip in the three types of sheath, the regular type, supported type, and supported type with supporting guide wire, were 8.40+/-0.51 cm, 6.23+/-0.41 cm, and 4.47+/-0.32 cm, respectively (p < 0.001). In the coil catheter application, the corresponding values were 7.22+/-0.70 cm, 5.61+/-0.31 cm and 3.91+/-0.59 cm, respectively (p < 0.001). All three types of sheath rotated smoothly and enabled both the wires and catheters to be guided toward the pylorus of the dog in all cases. CONCLUSION: The newly designed sheaths can be useful for gastroduodenal intervention.

PURPOSE: To compare the image quality of UGIS (upper gastrointestinal series) obtained by direct radiography with that of UGIS obtained by indirect radiography in a mass screening program for gastric cancer, and to assess the validity of UGIS by indirect radiography. MATERIALS AND METHODS: A total of 994 persons participated in a mass screening test for gastric cancer between March 2003 and April 2003 at the Korea Association of Health Promotion (KAHP). Of these 994 persons, 494 underwent UGIS by direct radiography, while the remaining 500 underwent UGIS by indirect radiography (i.e. photofluorography using a mirror camera and a 100 mm-roll film). We compared the image quality of UGIS obtained by direct and indirect radiography with, in each case, the image quality being graded as 'excellent', 'good', 'fair', 'poor' or 'very poor'. RESULTS: The image quality of UGIS by both direct and indirect radiography was similar: most images in both groups were rated as either 'excellent', 'good', or 'fair', while the incidences of poorly rated images were similar in both cases (5% versus 6%, respectively); and there were no images rated as 'very poor' in either case. For certain sites of the stomach, the image quality of UGIS by direct radiography was superior to that of UGIS by indirect radiography, namely at the cardia (p<0.001) and duodenum (p=0.001). However, for other sites of the stomach, the image quality of UGIS by both direct and indirect radiography was similar, namely at the body (p=0.043) and pylorus (p>0.05). CONCLUSION: There was no significant difference in the image quality between UGIS by indirect and direct radiography. Therefore, UGIS by indirect radiography may be used as a method of mass screening for gastric cancer.

Intestinal atresia is a frequent cause of intestinal obstruction in the newborn. We reviewed the clinical presentation, associated anomalies, types of atresias, operative managements, and early postoperative complications in 36 cases of intestinal atresia treated at the Department of Surgery, Kyungpook National University Hospital between January 1994 and February 2003. Location of the lesion was duodenum in 17 patients, jejunum in 11 patients and ileum in 8 patients. The male to female ratio was 1:1.4 in duodenal atresia (DA), 2.7:1 in jejunal atresia (JA) and 7:1 in ileal atresia (IA). The most common type was type III (41.1 %) in DA, and type I (52.6 %) in JA and IA. The most common presenting symptoms was vomiting(88.2 %) in DA, but in jejunoileal atresia, vomiting(89.4 %) and abdominal distension(89.4 %) were the most common sign and symptom. All cases of DA were diagnosed by plain abdominal radiography. There were 6 cases of DA with congenital heart disease, 3 cases of DA with Down syndrome and 3 cases of JA with meconium peritonitis. Segmental resection was performed in 13 cases, duodenoduodenostomy in 11 cases, membrane excision in 7 cases, jejunojejunostomy in 2 cases, gastroduodenostomy in 2 cases and ileocolic anastomosis in 1 case. There were 9 postoperative complications including 3 each of anastomotic leakage, wound infection, and intestinal obstruction 3 cases. The mortality rate for DA was 11.8 %(2/17). Both deaths in DA were attributed to congenital heart disease. The mortality rate for JA was 18% (2/11). Both cases died with sepsis and short bowel syndrome.
