ABSTRACT
The patient was a 73-year-old man who was referred to our hospital for increasing bilateral lung nodules. Video-assisted left S9-10 segmentectomy and right S1, S3 partial resection were performed separately for suspect of synchronous double lung cancer. Colonoscopy was performed because left lung tumor was difficult to distinguish between primary lung cancer and metastatic lung cancer. Colonoscopy did not find advanced cancer lesion. We diagnosed the left lung tumor as pT1b, cN0, cM0, Stage â A2 intestinal adenocarcinoma. The right lung tumor was diagnosed as pT1c, cN0, cM0, Stage â A3 papillary adenocarcinoma. Intestinal adenocarcinoma is a rare tissue subtype of lung adenocarcinoma and colonoscopy is useful modality for ruling out metastatic colorectal cancer.

High-resolution Rutherford backscattering spectrometry (HRBS) in combination with grazing angle argon sputtering was carried out to characterize the interface of aluminum-nickel (Al-Ni) alloy and amorphous-silicon films in a thin film transistor (TFT) for liquid crystal display (LCD). After thinning the top Al-Ni layer by a 1-keV Ar sputtering, the sensitivity of the interface oxygen was improved to be twice higher than that before sputtering. The results revealed that the oxygen at the interface relates to the contact characteristics.
ABSTRACT
AIM: To elucidate how spontaneous localized intestinal perforation (SLIP) is related to intestinal morphological features such as dilatation in very-low-birthweight (VLBW) infants. METHODS: The medical records of 13 VLBW infants (<1500 g) undergoing laparotomy between 1983 and 2003 for presumed SLIP were retrospectively reviewed. Clinical findings including maternal, prenatal and perinatal factors were analysed, and the clinical and surgical findings upon laparotomy were compared. RESULTS: Postnatal pathological conditions included patent ductus arteriosus (n=7), sepsis (n=2), respiratory distress syndrome (n=7), intraventricular haemorrhage (n=2), an indwelling catheter via the umbilical vein (n=1) and pneumonia (n=1). Indomethacin was used in seven neonates with patent ductus arteriosus, and dexamethasone preventive therapy was employed in one neonate for bronchopulmonary dysplasia. Operative findings revealed a localized small punched-out perforation in the ileum. Five patients had intestinal dilatation: two with a perforation in the middle of the dilated intestine, and three with a perforation proximal to the region of dilatation. The muscularis propria was absent in the dilated intestine of four patients. CONCLUSION: This study found no significant relationship between perforation and dilatation of the intestine. Perforation may occur in any portion of the ischaemic intestine when circulatory failure becomes severe, and is not necessarily restricted to the dilated intestine. We believe that SLIP and intestinal dilatation may occur on the same basis in low-birthweight infants; however, the disease process may be aetiologically different.

We describe here three cases of pancreatitis after congenital choledochal cyst excision. In these three cases, the choledochal remnant in the pancreas head was markedly dilated, probably because of an incomplete resection of the cyst at the primary operation, and an increase in intraluminal pressure of the pancreatic duct caused by a dynamic obstruction by a protein plug or a pancreatic calculus. Complete cyst excision, including the choledochal wall in the pancreas, is therefore strongly recommended.
