A randomised double-blind controlled phase III study to compare the efficacy and safety of intravenous ferric carboxymaltose with placebo in patients with anaemia undergoing major open abdominal surgery

Study Area: Surgical

Aim: To determine if a single dose of intravenous iron administered to patients with anaemia prior to major surgery reduces the need for peri-operative blood transfusion. Also to evaluate the effect of intravenous ferric iron compared with placebo on health related quality of life, post-operative morbidity, safety and length of hospital stay

Who can participate: Men and women aged over 18 who are planned for an elective open abdominal surgery and have been found to be anaemic (Haemoglobin blood test result  between 130-90 g/L for men and 120-90 g/L for women).

Chronic Constipation treatment of surgical treatment for adults

Study area: Surgery

Aim: Primary aim to determine the efficacy of laparoscopic ventral mesh rectopexy compared to controls at short term follow up (24 week post-surgery).

Who can participate: Adults 18-70 years with chronic constipation with self reported symptom duration >6 months, failure with laxatives and lifestyle modifications, failure of previous nurse led conservative therapies. Surgically correctable pelvic floor abnormalities.
