Article Synopsis
- Immediate decompression and chemotherapy are essential for patients with obstructive colorectal cancer and liver metastasis.
- In a case study, two patients received systemic chemotherapy after having self-expandable metallic stents (SEMS) placed due to obstructive sigmoid cancer.
- The chemotherapy caused shrinkage of tumors, which allowed for SEMS adjustment and the introduction of an anti-VEGF drug, resulting in successful treatment without complications.
Introduction: Colonic stent insertion is widely used as a bridge to surgery(BTS)for obstructive colorectal cancer. Stenting can shorten hospitalization and decrease complication and colostomy rates in comparison with emergency surgery. We investigated patients who underwent colonic stent insertion for BTS in our hospital.

This study was undertaken to assess diagnosis of metastasis in dissected lymph nodes through quantitative evaluation of the expression of carcinoembryonic antigen mRNA (CEA mRNA) by a rapid, simple transcription-reverse transcription concerted reaction (TRC) assay using dissected lymph node washings.
Methods: A total of 110 dissected lymph nodes from 40 patients undergoing surgery for gastric cancer were studied.
