A novel use for the rigid cystoscope: the removal of sacral tacks after a coloanal anastamosis dehiscence.

A 69-year-old female presented as an emergency with atrial fibrillation, which was treated with warfarin. She subsequently developed fresh rectal bleeding and after further investigations a Dukes B adenocarcinoma of the rectum was found. She subsequently underwent a low anterior resection, coloanal anastamosis and a defunctioning ileostomy. Three sterile surgical metallic tacks (pins) were inserted into the sacrum to stop brisk bleeding from the presacral venous plexus. Following discharge, she was readmitted with septic shock and a CT scan revealed a presacral fluid collection in the area surrounding the sacral tacks (pins) and an anastamotic dehiscence. The patient was not fit for further pelvic surgery to remove the tacks, so an alternative minimally invasive cystoscopic procedure was performed. The sacral tacks (pins) were removed by the urologist using a rigid cystoscope and cold cup biopsy forceps. To our knowledge, this is the first reported case in the literature.

Radiofrequency ablation (RFA) as a cytoreductive strategy for hepatic metastasis from breast cancer.

INTRODUCTION: Patients with liver metastasis from breast cancer have a poor prognosis, although this may be improved by hepatectomy in a selected group with disease confined to the liver. We evaluate the effectiveness of radiofrequency ablation (RFA) as a cytoreductive strategy in the management of liver metastasis from primary breast cancer. PATIENTS AND METHODS: Nineteen patients with hepatic metastasis from primary breast cancer underwent RFA of their liver lesions between April 1998 and August 2004. RESULTS: The median age of the patients was 52 years (range, 32-69 years), 8 had disease confined to the liver, with 11 having stable extrahepatic disease in addition. Seven patients with disease confined to the liver at presentation are alive, as are 6 with extrahepatic disease, median follow-up after RFA was 15 months (range, 0-77 months). Survival at 30 months was 41.6%. In addition, 7 patients followed up for a median of 14 months (range, 2-29 months) remain alive and disease-free. RFA failed to control hepatic disease in 3 patients. RFA was not associated with any mortality or major morbidity. CONCLUSIONS: Control of hepatic metastasis from breast cancer is possible using RFA and may lead to a survival benefit, particularly in those patients with disease confined to the liver.

Tumour angiogenesis: the relevance to surgeons.

INTRODUCTION: Angiogenesis is the process of new blood vessel formation from pre-existing vessels, and is a key feature of malignant tumours. Surgeons involved in the management of patients with malignant disease need to be aware of angiogenic mechanisms and their surgical implications. PATIENTS AND METHODS: A literature search was used to review recent developments in our understanding of the factors and processes involved in tumour angiogenesis, and how these will impact on the care of patients with malignant disease encountered by surgeons. RESULTS: Angiogenesis is fundamental to all stages of the malignant process, and involves a complex interaction between mediators secreted by tumour cells and host cells. Intense investigation continues into therapies targeting components of the angiogenic cascade. Imaging modalities capable of measuring the angiogenic activity of a tumour are also being studied in order to predict prognosis and select suitable patients for anti-angiogenic therapy. CONCLUSIONS: As the use of these anti-angiogenic therapies becomes more wide-spread, they may have implications on the healing rates of cutaneous wounds and intracorporeal anastomoses.

Recent randomised trials in colorectal disease.

Progress in colorectal surgery over the last few years is evident by the growing number of randomised controlled trials reported. We have scrutinised such trials reported over the last year across the entire spectrum of colorectal disease and have presented the significant findings in this trials report.
