[A case of diaphragmatic hernia following colonoscopy].

An 89-year-old woman with a history of traumatic injury was referred to our hospital for further evaluation of anemia. Two days after colonoscopy, she complained of intermittent abdominal pain. An abdominal computed tomography confirmed a left diaphragmatic defect with a herniated transverse colon.

Changes in CO2 concentration increase the invasive ability of colon cancer cells.

Background/aim: We studied the effects of CO(2) concentration changes on the invasive ability of colon cancer cells.

Materials And Methods: Colon cancer cell lines and human samples derived from a peritoneal metastasis were incubated in a hypercapnic environment, followed by incubation in 5% CO(2). The invasive ability of colon cancer cells incubated with CO(2) were analyzed using an invasion assay system.

Clinicopathological study of the colorectal mucinous carcinomas.

Histopathologically, the incidence of mucinous carcinomas in Europe and the United States is approximately 10% and that in Japan is low, at 2.9% to 7.4%.

[A case of recurrent colon cancer with urinary bladder, para-aortic lymph nodes, and spleen metastases successfully treated with CPT-11].

The patient was a 71-year-old woman with sigmoid colon cancer with urinary bladder invasion, for which sigmoidectomy with D 3 lymphadenectomy and partial cystectomy was performed. After surgery, the patient was started on 4 courses of 6-week systemic chemotherapy (500 mg/m(2) 5-FU and 200 mg/m(2) l-LV weekly). However, 4 months later, CT revealed local recurrence in the urinary bladder and recurrence in the para-aortic lymph nodes and spleen.
