Preoperative Diagnosis of Adult Intussusception Caused by Small Bowel Lipoma

Adult intussusception is rare, accounting for only 5% of all intussusceptions, for which preoperative diagnosis is difficult. We herein report a preoperatively diagnosed case of adult intussusception caused by a small bowel lipoma. A 33-year-old man was admitted to our hospital with three weeks history of colicky epigastric pain. Computed tomography revealed thickening of the ileal wall suggestive of intussusception. Colonoscopy revealed an ileocolic intussusception. Barium enema for reduction of ileocolic intussusception demonstrated a small bowel tumor in the ileum 15 cm proximal to the ileocecal valve. The intussusception was reduced, and the patient underwent partial resection of the ileum encompassing the small bowel tumor. Histological findings confirmed the diagnosis of lipoma of the small bowel. The patient made a satisfactory recovery and remains well

Leukocytapheresis Therapy Improved Cholestasis in a Patient Suffering from Primary Sclerosing Cholangitis with Ulcerative Colitis

Primary sclerosing cholangitis (PSC) is an autoimmune disease of the hepatobiliary system for which effective therapy has not been established. Leukocytapheresis (LCAP) therapy is known to effective in patients with ulcerative colitis (UC). In addition, effects of LCAP therapy were reported on some autoimmune diseases such as Crohn's disease, rheumatoid arthritis and rapidly progressive glomerulonephritis. Here we report the case of a 29-year-old man with PSC associated with UC who was treated with LCAP therapy. He had a 16-year history of UC and a 12-year history of PSC. Although he was under treatment with prednisolone and ursodeoxycholic acid, exacerbation of UC and PSC-associated cholestasis were seen. Since he showed side effects of prednisolone, he was treated with LCAP. Not only improvement of UC, but also decreased serum alkaline phosphatase, γ-guanosine triphosphate and total bile acids, suggesting improvement of PSC-associated cholestaisis, were seen after treatment with LCAP. Our experience with this case suggests that LCAP therapy could be a new effective therapeutic strategy for patients with PSC associated with UC

Carcinoembryonic antigen and carbohydrate antigen 19-9 are prognostic predictors of colorectal cancer with unresectable liver metastasis

No evidence currently exists to demonstrate the prognostic value of serum carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) in patients with unresectable colorectal cancer liver metastases (CRLM). Therefore, we retrospectively investigated the correlation between serum CEA and CA19-9 levels and overall survival in patients with unresectable CRLM. The study involved 40 patients who were diagnosed with unresectable CRLM between March 2000 and August 2010 at Jikei University Hospital, Japan. We retrospectively investigated the correlation between patient characteristics, including serum CEA and CA19-9 levels, and overall survival using univariate and multivariate analyses. In the univariate analysis, the absence of primary tumor resection (p=0.0161), the absence of systemic chemotherapy (p=0.0119), serum CEA ≥100 ng/ml (p=0.0148) and CA19-9 ≥100 U/ml (p<0.0001) were significant predictors of poor survival. In the multivariate analysis, the absence of systemic chemotherapy (p=0.0356), serum CEA ≥100 ng/ml (p=0.0079) and CA19-9 ≥100 U/ml (p=0.0002) were independent predictors. Serum CEA and CA19-9 levels are therefore independent prognostic predictors of survival in patients with unresectable CRLM
