Breath hydrogen and methane levels in a patient with volvulus of the sigmoid colon.

Volvulus of the large bowel is the third most common cause of colonic obstruction. A patient with colonic obstruction or delayed small intestinal transit may frequently have bacterial overgrowth and increased breath hydrogen (H(2)) and/or methane (CH(4)) excretion because the bacterium can contact with food residues for a longer time. A 39 year old woman attended our hospital with complaints of abdominal pain and distension.

[Case report of a liver metastasis from rectal cancer achieving complete response (CR) by a combination of intra-hepatic arterial infusion of irinotecan (CPT-11) with degradable starch microspheres (DSM) and weekly high-dose intra-hepatic arterial chemotherapy with 5-FU].

A 67-year-old woman, who was diagnosed with rectal cancer and liver metastasis, underwent a low anterior resection of the rectum in May 2004. Two months later, the level of tumor markers increased and a CT scan revealed a 45 x 35 mm liver metastasis in the S(8) segment. She was referred to our hospital for treatment of the liver tumor.
