Prucalopride for the treatment of ileus.

INTRODUCTION: Postoperative ileus (POI) is an impairment of coordinated gastrointestinal (GI) motility that develops as a consequence of abdominal surgery and is a major factor contributing to patient morbidity and prolonged hospitalisation. Despite the availability of various options its treatment is still under debate. This review will focus on effect of Prucalopride (5-HT4 receptor agonist) on postoperative ileus based on the existing literature. Areas covered: A literature search of MEDLINE, EMBASE and COCHRANE Library was performed concerning topics related to the treatment of ileus with prucalopride. The search strategy also included articles relating to other treatments of ileus for comparison with prucalopride. Expert opinion: Postoperative ileus remains difficult to treat and most strategies encompass preventative measures through enhanced recovery after surgery and laparoscopic approaches. The role of pharmacological intervention is developing with some drugs licensed for use. The evidence for prucalopride remains unclear although there is randomised controlled trial (RCT) evidence available. Given the potential for reduction in patient morbidity and length of stay the role of prucalopride in POI should be further investigated with multi-centre RCTs to establish which group of patients will gain the most from this exciting potential treatment.

Transanal endoscopic microsurgery.

Transanal endoscopic microsurgery (TEMS) is a well established method of accurate resection of specimens from the rectum under binocular vision. This review examines its role in the treatment of benign conditions of the rectum and the evidence to support its use and compliment existing endoscopic treatments. The evolution of TEMS in early rectal cancer and the concepts and outcomes of how it has been utilised to treat patients so far are presented. The bespoke nature of early rectal cancer treatment is changing the standard algorithms of rectal cancer care. The future of TEMS in the organ preserving treatment of early rectal cancer is discussed and how as clinicians we are able to select the correct patients for neoadjuvant or radical treatments accurately. The role of radiotherapy and outcomes from combination treatment using TEMS are presented with suggestions for areas of future research.

Management of renal tumors by image-guided radiofrequency ablation: experience in 105 tumors.

AIMS: In this article we present our experience with radiofrequency ablation (RFA) in the treatment of 105 renal tumors. MATERIALS AND METHODS: RFA was performed on 105 renal tumors in 97 patients, with a mean tumor size of 32 mm (11-68 mm). The mean patient age was 71.7 years (range, 36-89 years). The ablations were carried out under ultrasound (n = 43) or CT (n = 62) guidance. Imaging follow-up was by contrast-enhanced CT within 10 days and then at 6-monthly intervals. Multivariate analysis was performed to determine variables associated with procedural outcome. RESULTS: Eighty-three tumors were completely treated at a single sitting (79%). Twelve of the remaining tumors were successfully re-treated and a clinical decision was made not to re-treat seven patients. A patient with a small residual crescent of tumor is under follow-up and may require further treatment. In another patient, re-treatment was abandoned due to complicating pneumothorax and difficult access. One patient is awaiting further re-treatment. The overall technical success rate was 90.5%. Multivariate analysis revealed tumor size to be the only significant variable affecting procedural outcome. (p = 0.007, Pearson chi(2)) Five patients had complications. There have been no local recurrences. CONCLUSION: Our experience to date suggests that RFA is a safe and effective, minimally invasive treatment for small renal tumors.

Solitary, late metastatic recurrence of renal cell carcinoma: two extraordinary cases.

Late recurrence of renal cell carcinoma (RCC) has been well documented in the literature. We present two extraordinary cases of solitary, late metastatic recurrence of RCC. The first is a case of a solitary, adrenal metastasis excised 38 years after nephrectomy and the second is a case in which two solitary metastatic deposits were resected 14 and 26 years after excision of the primary tumor. In each of these patients the solitary metastases were initially believed to be primary tumors at other sites; however, on histological examination they were found to be metastatic RCC recurrences. In patients with a previous history of RCC presenting with apparently new solitary lesions, metastatic RCC must first be excluded.
