Virtual CT colectomy by three-dimensional imaging using multidetector-row CT for laparoscopic colorectal surgery.
Laparoscopic colorectal surgery has been attracting attention for its capacity to improve the quality of life (QOL) of patients. However, there are disadvantages to this approach, namely, it is difficult to obtain an image of the entire view of the operative field, and organs and lesions cannot be manipulated directly by the surgeon during surgery. For this reason, it takes a relatively large amount of time to ligate vessel, which can vary between patients. Furthermore, vessels and organs can be damaged during lymph nodes dissection under laparoscopic guidance, leading to heavy bleeding that prevents the surgeon from having access to a good view of the operative field. Then, to assess preoperatively the vascular anatomy, we carried out multiphase, contrast-enhanced examinations using multidetector-row CT (MDCT) on patients with colorectal cancer, and prepared the fused image of 3D images of arteries, veins, the colorectum, organs, and tumor. We called the utilization of 3D imaging virtual CT colectomy, which contributed to rapid and safe manipulation of the origins of the arteries and the veins, as well as lymph nodes dissection, without incurring injury to the involved arteries and veins.

Thin-section CT features of intrapulmonary lymph nodes.
PURPOSE: The objective of this study was to evaluate CT findings of pathologically proven intrapulmonary lymph nodes (IPLNs) and discuss the utility of thin-section CT and contrast-enhanced CT. METHOD: CT findings of 18 nodules in 14 patients with pathologically proven IPLNs were reviewed. CT scanning of the whole lung was performed contiguously with slice thickness of 10 mm. In addition, a helical scan with slice thickness of 2 mm was performed in nine patients, focusing on the nodule. Contrast-enhanced helical CT was performed in four patients, and the utility of thin section CT and contrast-enhanced CT was investigated. RESULTS: One patient had three nodules, 2 patients had two nodules, and the remaining 11 patients had a solitary nodule. All nodules were located below the level of the carina and within 15 mm of the pleura. In one case, conventional CT revealed the nodule 20 mm away from the pleura; however, the nodule attached to the major fissure was clearly revealed on thin-section CT. The size of the nodules was < or =15 mm, and the shape was round (n = 8), oval (n = 9), or lobulated (n = 1) with sharp border. One nodule demonstrated a spiculated border due to a surrounding pulmonary fibrosis on conventional CT; however, thin-section CT showed precisely a sharp border. The lobulated shape of one case histopathologically reflected a hilus of lymph node. On contrast-enhanced helical CT, all four nodules were enhanced and the degree enhancement was 36-85 HU (median 66.6 HU). CONCLUSION: In current times, IPLNs are not uncommon lesions. We should consider IPLN in the differential diagnosis of solitary or multiple pulmonary nodules in the peripheral field and below the level of the carina. Thin-section CT showed precisely the border or relation between IPLNs and the surrounding structure. It was difficult to distinguish between IPLNs and malignant nodules from the degree of enhancement on contrast-enhanced CT. On thin-section and contrast-enhanced CT, the findings of IPLNs are not necessarily specific. Therefore, strict observation on CT is necessary; in certain cases that are increasing in size, video-assisted thoracic surgery should be considered because of their location.

Validation of the defining characteristics of body image disturbance in Japan.
PURPOSE: To examine the validity of the nursing diagnosis body image disturbance and to specify its major and minor defining characteristics in Japanese culture. METHODS: A qualified sample of 149 RNs with an average of 10 years of clinical experience and knowledge of nursing diagnosis was given a questionnaire consisting of 21 defining characteristics from NANDA, 8 additional items from the literature, and 2 distracting characteristics. FINDINGS: Four major diagnostic content validation (DCV) scores of 0.75 and higher and 15 minor defining characteristics with DCV scores from 0.60 to 0.74 were identified. CONCLUSIONS: This study provides a foundation for further study of culturally appropriate defining characteristics for use in Japan.

Management of intractable pain in adiposis dolorosa with intravenous administration of lidocaine.
Intractable pain in a patient with adiposis dolorosa (Dercum's disease) was treated by IV administration of lidocaine (200 to 400 mg). Relief was maximum 20 minutes after the end of drug infusion and persisted for over 10 hours. Toxicity was minimal. Slow EEG waves which appeared during drug administration disappeared within 20 minutes.

Two adult cases of primary small bowel volvulus: usefulness of computed tomographic diagnosis.
Small bowel volvulus is usually secondary to conditions such as malrotation, congenital bands, postoperative adhesions, and internal hernias. Primary small bowel volvulus in an adult is rare, and only 14 cases had been reported in Japan as of 1994. Preoperative diagnosis is difficult, because clinical examinations and plain films are of limited diagnostic value. In our cases, CT showed signs of small bowel volvulus such as a U-shaped configuration or radial distribution of distended and fluid-filled loops of the small bowel converging toward the point of torsion, tightly twisted mesentery around the point of torsion (whirl sign), fusiform tapering loop (triangular sign in the cross section or beak sign in the longitudinal section), and signs of bowel ischemia or infarct such as attached mesenteric fluid and blurred mesenteric folds. CT enabled us to diagnose not only small bowel volvulus but also bowel ischemia or infarct.

Case report: MR findings of a retained surgical sponge.
We describe here a case in which a retained surgical sponge progressed into the perirenal space and posterior pararenal space from the pelvic cavity. Sonography, CT, and T1-weighted MR image analyses could not show clearly the characteristic structure of the surgical sponge, but T2-weighted MR imaging showed a folded fabric appearance within the cystic mass. Surgical findings confirmed a lobulated cystic mass containing yellowish fluid and a surgical sponge.

Case report: MR findings of Guillain-Barré syndrome.
Guillain-Barré syndrome (GBS) is characterized as an acute, symmetrically progressive, inflammatory demyelinating polyneuropathy. We report a case of GBS in which gadolinium-enhanced magnetic resonance (MR) imaging showed marked enhancement of nerve roots of the conus medullaris and cauda equina. On enhanced MR imaging, the spinal cord and nerve roots in the thecal sac generally do not take up much gadolinium because of the blood-nerve barrier or blood-brain barrier. Therefore, in our case, marked enhancement of nerve roots indicates a breakdown of the blood-nerve barrier. It is thought to correlate with the inflammatory infiltration of GBS.

An adult case of retropharyngeal cellulitis; diagnosis by magnetic resonance imaging.
We experienced an adult case of cellulitis in the prevertebral space with retropharyngeal and danger space, and, which was suspected to be due to a fish bone stuck in the throat. Its lesion could not be demonstrated on plain radiograph, postcontrast computed tomography, or laryngoscopy, but noncontrast magnetic resonance imaging demonstrated the lesion and was useful in assessing the efficacy of medication.

Ectopic ureter draining into seminal vesicle cyst: usefulness of MRI.
Ectopic ureter draining into seminal vesicle cyst is very rare congenital anomaly, which is thought to be caused by ectopic ureteral bud arising on the mesonephric duct. It is often associated with ipsilateral renal agenesis. We experienced a case of ectopic ureter draining into seminal vesicle cyst that is associated with ipsilateral renal agenesis. Generally, an invasive modality, that is, cyst puncture, cystography, or seminal vesiculography, is essential in the confirmative diagnosis of ectopic ureter. However, we could establish a definitive diagnosis with magnetic resonance imaging.
