Serum concentrations and side effects in psychiatric patients during risperidone therapy

PURPOSE: Evaluation of fluoroscopic stent placement as an emergency therapeutical approach for treatment of acute large bowel obstruction due to colorectal neoplasm. METHODS AND MATERIAL: From January to December 1996 in 11 patients suffering from colorectal stenosis due to known or supposed malignancy the indication for the fluoroscopic placement of self-expanding metal stents was established. All patients showed clinical and radiological signs of an acute mechanical large bowel obstruction. Elective single-stage surgery was planned if the decompression had been carried out successfully. RESULTS: Stent placement was successful in 8 cases. Functional success in respect of resolving the acute large bowel obstruction was seen in 7 out of 11 patients. Elective surgery was possible in all 7 cases creating a primary end-to-end anastomosis without major complications during the perioperative period. CONCLUSION: Fluoroscopic placement of self-expanding metal stents in malignant colorectal stenosis is a promising method to avoid emergency surgery.
