OBJECTIVE Abdominal rectopexy is ideal for otherwise healthy patients with rectal prolapse because of low recurrence, yet after posterior rectopexy, half of the patients complain of severe constipation. Resection mitigates this dysfunction but risks a pelvic anastomosis. The novel nerve-sparing ventral rectopexy appears to avoid postero-lateral rectal(More)
OBJECTIVE Over the last 15 years, posterior rectopexy, which causes rectal autonomic denervation, was discredited for internal rectal prolapse because of poor results. The condition became medical, managed largely by biofeedback. We aimed to audit the short-term functional results of autonomic nerve-sparing laparoscopic ventral rectopexy (LVR) for internal(More)
BACKGROUND A loop ileostomy is a common adjunct to formation of a low colorectal anastomosis. However, it is not without significant physical and psychological morbidity, and financial cost. Feasibility of early closure during the index admission has previously been reported. This pilot study examines the safety of early closure compared with traditional(More)
AIM The nature and clinical significance of internal rectal prolapse is controversial. Its natural history is unclear. Longitudinal cohort studies show rare progression to external prolapse but lack adequate follow-up. We aimed to study the relationship of age to various stages of internal rectal prolapse using the Oxford Rectal Prolapse Grade (ORPG) and(More)
BACKGROUND The aetiology of faecal incontinence is multifactorial, yet there remains an approach to assessment and treatment that focusses on the sphincter. Rectal intussusception (RI) is underdiagnosed and manifests primarily as obstructed defecation. Yet greater than 50% of these patients admit to faecal incontinence on closer questioning. We aimed to(More)
PURPOSE Liver surgeons usually recommend against biopsy of colorectal liver metastases because of the risk of local dissemination. To date, only case reports describing this problem have been published. This study is an attempt to quantify the risk of biopsy-related dissemination. METHODS A multicenter, retrospective review was undertaken of cases of(More)
Transanal endoscopic microsurgery (TEM) has an established role in the management of benign rectal tumors. It also has an expanding role in the management of malignant tumors, which is more demanding for the clinician. It requires accurate histological and radiological assessment and draws on an expert understanding of the nature of local recurrence,(More)
