Abstract
BACKGROUND AND OBJETIVES: Due to the potential risks associated with stent placement, European Society Gastrointestinal Endoscopy does not recommend prophylactic insertion of stents in patients without symptoms. The aim was to compare complication rates, need of surgery, colostomy formation, and survival between stent placement prior to start of chemotherapy (SEMS group) and upfront ChT (ChT group) in patients with endoscopically non-transverable metastatic left-sided colorectal cancer. METHODS: Gender, age, CEA, tumor location, sites of metastatic disease, peritoneal involvement, liver involvement, and angiogenesis inhibitors administration, were recorded. Complication rates, need of surgery, stoma creation, and survival were compared between both groups by univariate and multivariate test. Complications of SEMS placement in both groups were compared. RESULTS: We studied 75 men and 40 women, with a mean age of 66.3 years. Overall complication and perforation rates were similar but patients in the ChT group had a significant higher need of surgery and subsequent stoma creation. Perforation after SEMS placement rates were higher in patients receiving ChT than in patients without ChT. Survival was related to peritoneal carcinomatosis and administration of biological agents. CONCLUSIONS: SEMS placement prior to ChT administration dismissed the need of subsequent surgery and decreased the rates of permanent stoma formation.
