Evaluation of complications related to therapeutic colonoscopy using the bipolar snare.

Background: The complications with therapeutic colonoscopy reported to date have been associated with the monopolar snare, and the frequency of complications related to use of the bipolar snare is uncertain. This study aimed too investigate the incidence of bleeding and perforation associated with the bipolar snare and to identify the risk factors for bleeding.

Methods: Between October 2001 and December 2008, all patients with colorectal polyps treated using the bipolar snare were enrolled in this retrospective study.

[A surgical (pancreatoduodenectomy) case of lymph node metastatic recurrence of colon cancer after chemotherapy].

A woman in her fifties underwent a right hemicolectomy (D3) for cancer of the ascending colon in October 2007, definitively and pathologically diagnosed as papillary adenocarcinoma invading to the subserosa, and no metastasis was detected to lymph node. But 13 months after the surgery, she was found to have a mass near the anastomosis by an abdominal CT scan. Colonoscopy showed an evaluating lesion with ulcer in the anal side of the anastomosis.

[A surgical (right lobectomy) case of liver metastasis of colon cancer after chemotherapy using mFOLFIRI and cetuximab].

A man in his early seventies underwent low anterior resection and partial resection of the liver for the rectal cancer and liver metastasis. However, 4 months after the surgery, he was found to have a liver tumor at S5 and S7 by abdominal CT scan. Then, he underwent chemotherapy (mFOLFOX6), but the metastatic tumor was progressive.

[The introduction of the clinical study in the general hospital].

Our hospital fights against a clinical study clearly. However, our hospital did not participate in a clinical study here. When I widened a clinical study in cooperation with the staff, I make a progress report.
