Dr Weisi Xia is a surgical house officer who finished his medical studies at the University of Auckland and is employed as a medical practitioner in the Auckland region. He is currently pursuing a PhD in Surgery. He has interests in pursuing a career in academic surgery. Haemorrhoids are a common problem that has the greatest burden on the working age population. Surgery is required to treat those with advanced disease and is associated with significant pain. This PhD study will investigate how to reduce pain following haemorrhoid surgery. The project will utilise various methods including a systematic review, a retrospective cohort analysis and a randomised controlled trial to improve understanding in this field. The health, social and financial benefits will potentially improve patient morbidity, encourage earlier return to normal activity and reduce the burden on visits and readmissions to primary and secondary care.
