Background/Aims: Positron emission tomography-computed tomography (PET-CT) is a nuclear imaging technique that provides noninvasive, three dimensional, quantitative images. Recently, PET-CT has been shown to be valuable in assessing patients with inflammatory diseases; however, the clinical utility of PET-CT in the evaluation of inflammatory bowel disease (IBD) has not been defined. Thus, the aim of this study was to determine the clinical utility of PET-CT in the evaluation of IBD. Methods: Between November 2006 and September 2010, clinical,endoscopic, and radiological data on 14 patients (6 males and 8 females: age range, 33-79 years) with suspected IBD were collected. The standard work-up method for a definite diagnosis of IBD included ileocolonoscopy. Results:The 14 patients were divided into the following five groups: ulcerative colitis (n=4, 29%), intestinal Behcet’s disease (n=3, 21%), intestinal tuberculosis (n=2, 14%), malignancy (n=2, 14%), and no abnormal findings with colonoscopy (n=3, 21%). A PET-CT based-diagnosis of IBD correlated with a colonoscopic diagnosis in nine cases (64.3%),but the matching ratio of the distribution of lesions between PET-CT findings and colonoscopic findings was only 18.1% (2/11). Conclusions: The utility of PET-CT in the diagnosis of IBD requires further evaluation. (Intest Res 2011;9:97-104)

Background/Aims: Primary T-cell lymphoma of the gastrointestinal tract is a very difficult disease entity to diagnose, and has an extremely poor prognosis. The aim of this study was to determine the early diagnostic accuracy for gastrointestinal T-cell lymphoma by gastroenterologists. Methods: Between January 2000 and October 2010, the clinical features of 15 patients with primary gastrointestinal T-cell lymphomas, including endoscopic findings, radiologic diagnosis, endoscopic biopsy findings, and final diagnosis, were retrospectively reviewed. Results: The most common initial presenting symptoms of primary gastrointestinal T-cell lymphomas was abdominal pain (n=11, 73%). The anatomic location of the primary lesion the small bowel (n=8, 53%), colon (n=5, 33%), and stomach (n=3, 20%). There were no cases of T-cell lymphomas diagnosed based on clinical symptoms, radiologic findings, or endoscopic findings without biopsy alone. Pathologic confirmation of T-cell lymphomas by endoscopic examination was achieved in 7 cases (64%) and the remaining cases (n=8, 53%) were diagnosed with T-cell lymphomas based on pathologic examination after surgery. Conclusions: All of the patients with primary T-cell lymphomas of the gastrointestinal tract were diagnosed exclusively by endoscopic or surgical pathologic examainations, suggesting that gastroenterologists should scrutinize and suspect this disease with caution due to atypical gastrointestinal ulcers.

Aims: This study was designed to determine the incidence of altered sensation in patients undergoing orthognathic surgery. Method: Seventy two patients who underwent orthognathic surgery between January, 1999 and December, 1999 constituted the study group. Seven patients were excluded because of lack of follow up. Sixty five patients were followed using objective and subjective neurologic testing during the period immediately following operation, 1 month, 2 months, 6 months, and 1 year postoperatively. Age ranged from 17 to 38 years, with a mean of 24.5 years. Male patients were 21, female 44. Twenty eight bilateral sagittal splitting ramus osteotomy(BSSRO) of mandible were performed, 35 BSSRO with genioplasty, 2 genioplasties. Information on the degree of intraoperative nerve encounter was obtained from the surgical reports in 47 patients and was divided into the following three categories: (1) the nerve was not encountered in 23 patients; (2) the nerve was exposed in 11 patients; (3) the nerve was exposed and repositioned from the proximal segment in 13 patients. Results: Four patients reported altered nerve sensation of lower lip and/or chin(6.2%) at final follow up. Two patients underwent BSSRO and the other two patients BSSRO with genioplasty. Three of the patients underwent nerve exposure during the operation. Conclusion: We suggest that the nerve exposure during the operation might be partly responsible for nerve dysfunction after orthognathic surgery.
