Objective To evaluate the efficacy of interventional therapy for advanced pancreatic carcinoma. Methods 33 cases of advanced pancreatic carcinoma accepted interventional therapy from April 2005 were retrospectively analyzed. All patients were unoperable and accepted one or more times of celiac and superior mesenteric arterial chemotheraputics perfusion with dosage of 2:1. The embolization was further introduced with the addition of liver invasion. The repetition interval was kept at 6 weeks with no severe complications. Results The one with follow-up CT imagings showed obvious decrease of the lesion size, together with release or disappearance of the sensation of abdominal pain and abdominal distention. The life span prolonged with average survival of 13 months, including the longest of 22 months and the life quality improved. Conclusions The interventional therapy could be the first method of choice in the management of advanced pancreatic carcinoma.

Objective To observe the effect of pulsed radiofrequency (PRF) on refractory infraorbital neuralgia. Methods From January, 2012 to December, 2014, 49 patients who received ineffective conservative therapy including medicine and nerve blockade underwent PRF treatment. Postoperative Numeric Rating Scale (NRS)=0 or 50%diminution of NRS was considered effective. NRS, effective rate, addition-al carbamazepine dosage and side effects were recorded on the first day, the first week, the second week, the first month, the third month, the sixth month, the first year, and the second year after operation. Results The effective rate were 67%, 67%, 65%, 59%and 51%on the first month, the third month, the sixth month, the first year, and the second year after operation, respectively. No serious side effect was observed, except that eight patients felt short-term (within one month) mild numbness. Conclusion PRF technique is safe and effective for refractory infraorbital neuralgia, and may become an alternative therapy.

Objective To evaluate the CT features and the role of CT in the diagnosis of Crohn′s disease. Methods CT manifestations of 18 patients with pathology confirmed Crohn′s disease were retrospectively analyzed. The majority of the patients were scanned with spiral CT or multidetector row CT.Results All 18 patients, segmental thickening of the bowel wall was detected. There were two different appearances in contrast-enhanced CT scans: (1) mural thickening without enhancement or mural stratification, and homogeneous attenuation in the thickened wall were observed in 7 patients; (2) mural thickening and stratification, resulting in the target or double-halo appearance, were detected in 11 patients, and the bowel wall thickening ranged from 5 to 10 mm. Nine patients had perienteric abnormalities including fibrofatty proliferation, phlegmon and mesenteric hypervascularity. According to the CT manifestations, 5 patients were initially diagnosed as other diseases including intestinal obstruction (1 case), tuberculosis (1 case), cancer (2 cases), and abscess (1 case), respectively. Conclusion CT has the unparalleled ability to depict the abnormalities in the bowel wall, mesentery, abdominal and pelvic viscera, and contrast-enhanced CT can distinguish active Crohn′s disease from quiescent Crohn′s disease. These features make CT particularly valuable in the management of Crohn′s disease.

Objective To observe the effect of radiofrequency thermocoagulation on patients with refractory supraorbital neuralgia Methods From February, 2007 to September, 2014, 36 patients with refractory supraorbital neuralgia following ineffective conservative ther-apy including medicine and nerve blockade underwent radiofrequency thermocoagulation. Numeric Rating Scale (NRS), Patient Satisfaction Scale (PSS), onset time, effective rate, recurrence rate, additional carbamazepine dosage and side effects were recorded before, and one day, one month, three months, six months, one year, two years after treatment. NRS=0 or 50%diminution was considered effectively. Results It worked two days on average (zero to seven) after treatment. The NRS score decreased (P<0.05) and the PSS score increased (P<0.05) com-pared with the data before treatment. The effective rate was 100%within six months. The recurrence rate was 11.1%within two years. Sec-ond radiofrequency thermocoagulation treatment still worked for the recurrent patients. No other side effect was observed, except permanent frontal numbness, short-time palpebral edema and ecchymosis. Conclusion Radiofrequency thermocoagulation is effective on refractory su-praorbital neuralgia, and the side effects are tolerable so it is an alternative choice for patients experiencing invalid conservative therapy.

Objective To evaluate the information of head injury caused by the major earthquake of Wenehuan and the diagnostic value of muhi-slice spiral CT(MSCT). Methods A total of 1557 earthquake victims were hospitalized, of which head CT scan was performed in 292 eases, and abnormalities were found in 225 of them. The composition, type of injury and MSCT findings of head injury were retrospectively analyzed. Results CT abnormalities were found in 225 victims, including 66 cases of skull fracture,50 eases of cerebral contusion and laceration, 55 eases of intracranial hematoma, 16 cases of subaraehnoid hemorrhage, 16 eases of subdural collection of fluid,20 eases of foreign substance of scalp,and 2 eases of traumatic cerebral infarction. Operation was performed in 22 of them. Conclusion The incidence of head injury in earthquake was high, and most of them were not severe. The examination of MSCT was rapid, MPR and 3D images can clearly show the lesion of craniocerebral trauma. MSCT can provide more valuable information for clinical therapy in craniecerebral trauma caused by earthquake.
