    Abstract Inflammatory myofibroblastic tumors (IMTs) are neoplastic lesions characterized by the proliferation of spindle cells with myofibroblastic features and lymphocyte infiltration. Primary lesions can develop in several locations but rarely arise in the colon as described herein. The present case was that of a 69-year-old woman who visited our hospital with complaints of bloody bowel discharge and a prolapsed mass from the anus. A 20-mm tumor was identified on visual and digital examination. Lower gastrointestinal endoscopy revealed a pedunculated, elevated lesion above the dentate line, which showed contrast enhancement on abdominal computed tomography. The patient was preoperatively diagnosed with an anal polyp, which was resected transanally. During the procedure, a mobile tumor coated by anal epithelium was observed at the 11 o'clock position above the dentate line. Deeper parts of the tumor were contiguous with the internal anal sphincter (IAS) muscle. Suspecting a neoplastic lesion, we resected the mass

    Abstract Background/aims: Extended radical surgery might provide a survival advantage for patients with carcinoma of the head of the pancreas.
    Methodology: Between January 1980 and December 1999, 144 patients with carcinoma of the head of the pancreas were treated in a community hospital setting, of whom 69 patients who underwent radical surgery were retrospectively reviewed. Surgical procedures included standard pancreaticoduodenectomy (27 patients), pylorus-preserving pancreaticoduodenectomy (27 patients), and total pancreatectomy (15 patients). Portal vein resection was performed for 15 patients. Retroperitoneal lymphadenectomy was performed for 35 patients. No patients received adjuvant chemotherapy or radiotherapy.
    Results: The surgical resection rate was 47.9% with a surgical mortality rate of 4.3% during this period. The overall 5-year survival rate after radical surgery was 16.1% with a median survival of 12 months. Seven patients survived five years, making 16.3% of the patients available for a more than 5-year follow-up. Long-term survivors had less than two positive lymph nodes in the posterior pancreatic head. Fourteen of 15 patients undergoing portal vein resection died within 21 months. One patient having no portal vein invasion microscopically survived 27 months without recurrence.
    Conclusions: Extended radical surgery did not prolong survival for patients with carcinoma of the head of the pancreas.

    Abstract Background/aims: Contrast radiology predicts the outcome of treatment for patients with small bowel obstruction. The optimal method of contrast radiology to determine the indications for and timing of surgery is controversial.
    Methodology: Contrast radiology was performed for patients with postoperative adhesive small bowel obstruction between April 1, 2000 and March 31, 2001. Nearly 40 mL of gastrografin mixed with 40 mL of water was administered either orally or via a nasogastric tube to each patient within 24 hours of hospital admission. Serial erect and supine plain abdominal radiographs were taken 4, 8, 16 and 24 hour later.
    Results: Of 107 patients with postoperative adhesive small bowel obstruction, 97 patients had the examination completed. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of this study as an indicator for non-operative treatment were 98.9%, 66.6%, 96.9%, 97.8% and 80%. However, contrast radiology had little impact on the diagnosis of 6 patients with strangulated small bowel obstruction. Ninety-two of 93 patients (98.9%) who were resolved with non-operative treatment were resolved within 48 hours of hospitalization.
    Conclusions: Contrast radiology should be considered for patients with simple small bowel obstruction who did not improve with non-operative measures after 48 hours of hospitalization.
