Frequently Asked Questions
Is THD painful?expand_more
Most patients experience fairly low levels of pain, though it can be more noticeable in a minority. Regular painkillers and laxatives help manage this, and pain is generally significantly less than with a traditional haemorrhoidectomy, since no tissue is cut or removed.
How is THD different from a haemorrhoidectomy?expand_more
Haemorrhoidectomy removes the haemorrhoidal tissue surgically. THD instead ties off the arteries supplying the haemorrhoids, using a Doppler probe to locate them precisely, and repositions any prolapsed tissue if needed - without cutting or removing tissue. This generally means less pain and a quicker return to normal activities.
Will I need a general anaesthetic?expand_more
THD is usually performed under general or regional (spinal) anaesthesia as a day case. We'll discuss which option is most suitable for you beforehand.
How soon can I return to work?expand_more
Most patients return to work within 1-2 weeks, depending on the nature of their job.
Can haemorrhoids come back after THD?expand_more
It's possible, though recurrence rates are generally lower than with some other treatments. If haemorrhoids do return, further treatment such as a repeat THD or haemorrhoidectomy may be recommended.
