Having a growth removed from the rectum without any cuts on the abdomen is a relief for many patients, but it does not mean the body has nothing to heal.
The treated area is a surgical wound inside the rectum, and it needs time, care and a few sensible habits to recover well. Knowing what is normal and what isn't makes the first weeks far less stressful.
This guide explains how pain is usually controlled, what happens as the area heals and which symptoms need medical attention.
A smooth recovery from transanal endoscopic surgery depends on following your surgeon's instructions, keeping bowel movements soft and comfortable, and attending your follow-up visits, so we cover each in turn.

What Happens During the Procedure?
Transanal endoscopic surgery, which includes techniques such as transanal endoscopic microsurgery (TEM) and TAMIS, removes selected rectal polyps and early tumours through the anus using a specialised scope and fine instruments.
There is no abdominal incision. After the growth is removed, the defect left in the rectal wall is often closed with stitches inside the rectum.
Because the wound is internal, you will not see it or need to dress it. Healing happens quietly in the background, which is why comfort measures and bowel care matter so much.
How Much Pain Should You Expect?
Many patients are pleasantly surprised by how mild the pain is. Most describe discomfort, pressure, or a feeling of fullness in the back passage rather than sharp pain.
Pain tends to be greater if the growth was close to the anal opening, where the tissue is more sensitive.
Understanding transanal endoscopic surgery recovery can help patients know what to expect after the procedure, including how discomfort may vary depending on the location and extent of the treatment.
Other common sensations in the first days include:
- A feeling of needing to open your bowels even when empty
- Mild cramping or aching in the lower abdomen
- Slight swelling or a haemorrhoid-like sensation around the anus
- Tiredness after the anaesthetic
Studies of patients after TEM have reported low levels of pain overall, with most people able to walk the day after surgery. Individual experiences differ, so tell your care team if your discomfort is not well controlled.
Practical Ways to Manage Pain
Take pain relief as prescribed. Simple painkillers such as paracetamol are often enough, with additional medication only if your surgeon advises it. Taking doses at regular intervals in the first few days is usually more effective than waiting until the pain builds. Ask before using anti-inflammatory tablets if you take blood thinners.
Keep stools soft. Straining is the biggest avoidable source of pain after rectal surgery. Use the stool softener or fibre supplement recommended by your surgeon, drink plenty of fluids and eat fibre-rich foods.
Try warm sitz baths. Soaking the area in shallow warm water for 10 to 15 minutes can relax the muscles and ease discomfort, particularly after a bowel movement. Pat dry gently afterwards.
Move gently. Short, regular walks support circulation and bowel function. Avoid long periods lying in bed or sitting on hard surfaces.
Care for the skin. Rinse with warm water instead of wiping hard, use soft unscented tissue and wear loose cotton underwear.
How the Area Heals
Healing happens in stages, and knowing the pattern helps you recognise what is normal.
First few days. You may notice small amounts of blood, mucus or staining on your underwear or tissue. Some patients also have a mild temperature in the first day or two, which is not unusual, but you should report a fever to your team if it persists.
First two weeks. The wound gradually closes and the discomfort settles. Your bowels may feel unpredictable, with urgency, loose motions or a sense of incomplete emptying. This is partly because the anal sphincter muscles can be stretched during the procedure, causing temporary weakness that usually improves.
Weeks three to six. Bowel habits typically become more regular, and most people feel much closer to their usual selves. Occasional changes can persist longer after removal of larger lesions, so be patient and keep your surgeon informed.
Most patients can return to light daily activities within days to about a week, while strenuous exercise and heavy lifting should wait until your surgeon says it is safe.
A Note on Post-Procedure Inflammation
A small number of patients develop pain, fever or general unwellness during the first week due to a localised inflammatory reaction around the treated area.
A recent study of patients after TEM described this pattern, which typically appeared within the first few days to a week, and most people did not go on to develop further infection.
Because the symptoms can overlap with early complications, do not try to diagnose it yourself.
Contact your surgeon if you have fever, increasing pain or abdominal discomfort so that you can be checked.
Eating and Drinking During Healing
Most patients can eat normally soon after surgery, but a few habits protect the healing area:
- Eat small, regular meals with plenty of fibre from fruit, vegetables, oats and wholegrains
- Drink enough water throughout the day
- Limit foods that tend to cause loose or hard stools, depending on how your bowels respond
- Introduce changes gradually if you are taking iron tablets or strong painkillers, which can cause constipation
Warning Signs to Watch For
Some discomfort is expected, but contact your surgeon or go to the emergency department if you experience:
- Heavy bleeding or passing large clots
- Fever or chills
- Severe or worsening pain in the rectum, lower back, abdomen or pelvis
- Swelling, pus or a foul-smelling discharge
- Inability to pass urine or stool
- Feeling increasingly unwell after going home
Doctors often ask patients to watch for blood, fever or pain for two to three weeks after rectal procedures, since problems can appear after discharge. Early review makes complications easier to manage.
Follow-Up and Test Results
After surgery, the removed tissue is examined under a microscope. The results show whether the growth was benign or cancerous, and whether the edges were clear. This report guides what happens next.
In some cases, no further treatment is needed, while in others your surgeon may recommend additional imaging, closer monitoring or further surgery.
Regular follow-up scopes or scans are often arranged to check for recurrence, so keep these appointments even if you feel well.
FAQ'S
Usually not. Most patients experience discomfort or pressure rather than severe pain, which can be controlled with simple painkillers. Pain may be stronger if the growth was close to the anal opening.
Light bleeding, staining and mucus are common for a few days. Heavy bleeding, large clots or bleeding that worsens should be reported straight away.
Urgency, loose stools or a feeling of incomplete emptying can occur because the area is healing and the sphincter muscles may have been stretched. These changes usually improve over several weeks.
Many people resume light activity and desk work within days to about a week. Heavy lifting and strenuous exercise should wait until your surgeon gives clearance.
Call if you develop fever, heavy bleeding, severe or worsening pain, swelling or discharge, or you are unable to pass urine or stool.
Final Thoughts
For most patients, transanal endoscopic surgery recovery is smoother than recovery from major abdominal surgery, with mild to moderate discomfort and a relatively quick return to normal life.
Manage your pain on schedule, keep your stools soft, rest while staying gently active and report anything unusual early.
