BACKGROUND Parastomal hernia following formation of an ileostomy or colostomy is common. This article reviews the incidence of hernia, the technical factors related to the construction of the stoma that may influence the incidence, and the success of the different methods of repair. METHODS A literature search using the Medline database was performed to(More)
PURPOSE Expandable, metallic stents provide a new modality of palliation for patients with noncurable metastatic colorectal adenocarcinoma. This study was designed to compare the use of expandable metallic stents as a palliative measure to traditional open surgical management, with particular reference to length of stay, and survival. METHODS Patients(More)
PURPOSE Radiotherapy has become one of the most important treatment modalities for human malignancy. Tumors affecting the organs of the pelvis are increasingly being irradiated for local treatment benefit, with the subsequent complication of anorectal injury of varying extent. The aim of this review is to determine how to manage the consequences of(More)
Leptospira interrogans serovars pomona, hardjo and tarassovi were each used to inoculate 6 cattle. Three-hundred and ninety-nine sera collected from the inoculated animals and from a control group over a 3-month period were tested using the microscopic agglutination test (MAT) and the enzyme-linked immunosorbent assay (ELISA). Leptospiruria was monitored by(More)
AIM To compare patients having low Hartmann's resection (LHP) with abdominoperineal resection (APR) by investigating postoperative complications. METHODS Retrospective comparative analysis of preoperative state and postoperative course for patients having surgery from 1 January 1997 to 1 July 2001, by the surgeons of the Colorectal Unit, Christchurch(More)
PURPOSE Surgery remains the only option for potential cure in patients with recurrent colorectal cancer. Accurate staging modalities aid in the avoidance of futile surgery, which may result in considerable morbidity in patients with incurable disease. Current imaging techniques used in disease staging often are not sensitive enough to identify low-volume(More)
AIM Evidence suggests that follow-up after colorectal cancer improves survival. Colorectal cancer is so common that patient follow-up can overwhelm a service, affecting the ability to see new referrals and reassess patients seen previously who have new symptoms. In order to cope with this demand a nurse-led follow-up service was started in 2004. We aimed to(More)
Clinical responses of patients with blastomycosis to treatment with hamycin have been variable. An explanation for this was sought in a series of studies in which in vitro and in vivo susceptibilities to hamycin of five strains of Blastomyces dermatitidis were compared. Minimal inhibitory concentrations of hamycin for the five strains indicated uniformly(More)
BACKGROUND Emergency surgery for large bowel obstruction carries significant morbidity and mortality. After initially promising results, concerns have been raised over complication rates for self-expandable metal stents (SEMS) in both the palliative and bridge-to-surgery settings. This article documents the technique used at the authors' institution, and(More)
Aim: To see whether laparoscopy improves the accuracy of a clinical diagnosis of acute appendicitis in women of reproductive age, and to determine what the long-term sequelae are of not removing an appendix deemed at laparoscopy to be normal. Method: The initial part of the study was undertaken during 1991–1992. Female patients between 16 and 45 years were(More)
