Intersphincteric resection (ISR) is a procedure designed to preserve anal function in cases with very low rectal cancer. We report our clinical experience with laparoscopic ISR (Lap ISR) performed using needlescopic instruments. First, a camera port is created at the umbilicus. Two 5-mm ports are then inserted at the right upper and lower quadrants. Two(More)
INTRODUCTION Therapy comprising 5-fluorouracil, levofolinate, and oxaliplatin is currently the most common chemotherapy for colorectal cancer. We experienced a successful case of advanced colon cancer and recurrent breast cancer with 5-fluorouracil, levofolinate, and oxaliplatin therapy. CASE PRESENTATION A 43-year-old Japanese woman who had already(More)
Purpose: With the improvements in newer chemo-therapeutic agents, there is currently no consensus regarding the validity of palliative resection of the primary tumor for colorectal cancer with incurable distant metastasis.

The patient was a 68-year-old man who was admitted to our hospital with a liver tumor. Abdominal ultrasonography and computed tomography revealed a liver tumor 30 mm in diameter. On colonoscopy, a pedunculated tumor with a central depression (20 mm in diameter) was observed in the ascending colon, and this tumor was considered to be invading deeply into the(More)
The aim of this study was to evaluate the impact of laparoscopic surgery (Lap) on circulating free tumor cells in colorectal cancer patients. In this study, we selected carcinoem-bryonic antigen (CEA) mRNA expression in peripheral blood as the marker of the circulating tumor cells and compared this marker between Lap and open colectomy (OC), to investigate(More)
