Home Care

• A small amount of bleeding is common following rectal surgery. A sanitary napkin or gauze may be worn over the anal opening to keep the underclothing clean. If there is prolonged or profuse bleeding with passage of clots, call the office at once. In some patients a packing will have been placed in the anus at the end of the surgery. This will dissolve and pass with the first bowel movement.

• Difficulty urinating after surgery around the anus is usually due to spasm of the urinary sphincter resulting from pain due to the surgery. Getting the pain under control and relaxing the sphincter usually allows for the urine to pass. Take the pain medication you were prescribed and do warm sitz baths – either in a bath tub or sitz basin. While soaking, attempt to relax the bladder and urinate into the water.  If you are unable to urinate in the first eight hours after your surgery, notify the doctor’s office. After hours, go to the nearest emergency room or urgent care center. A bladder catheter will be placed and remain in place for 2 days, you may call the office to have the catheter removed. Once you have started to urinate, drink plenty of water and fruit juices (such as prune juice) after your surgery.

• You will be given a prescription for pain medication. Follow the directions given by your doctor for taking this medication. To avoid upset stomach, take your pain medication as prescribed with food in your stomach. Take these drugs exactly as directed. Never take more than the recommended dose, and do not take the drugs more often than directed. If the drugs do not seem to be working, call the office for advice. Do not share these or any other prescription drugs with others because the drug may have a completely different effect on the person for whom it was not prescribed. Some people experience drowsiness, dizziness, lightheadedness, or a false sense of well-being after taking these medicines.

• Anyone who takes these drugs should not drive, use machines, or do anything else that might be dangerous until they know how the drug affects them. Nausea and vomiting are common side effects, especially when first beginning to take the medicine. If these symptoms do not go away after the first few doses, check with the physician who prescribed the medicine. Side effects may include: dizziness, lightheadedness, nausea, sedation, vomiting, if these side effects occur, it may help if you lie down after taking the medication.

• Avoid strenuous activity for 1-2 weeks after your procedure.

• Ask someone to drive you to appointments until you are able to sit and move comfortably.

• Sit in 8 to 10 centimeters of warm water (sitz bath) for 15 to 20 minutes 3 times a day and after bowel movements. Then pat the area dry. Do this as long as you have pain in your anal area

• Avoid sitting on the toilet for long periods of time or straining during bowel movements.

• Don’t worry if you have some bleeding, discharge, or itching during your recovery. This is normal. However, if you have prolonged or profuse bleeding with the passage of clots call the office at once. If a stitch was placed during surgery, this may come out – that is not a cause for concern unless there is also bleeding.

• Do not take Aspirin products or NSAIDs (such as Motrin or Advil) for seven days, unless given permission to do so

• To avoid constipation take Benefiber or other psyllium product (Metamucil, Citrucel, etc) one teaspoon twice a day. Take a stool softener such as Colace or Miralax twice a day as well. You can also take MIralax AND a stolol softener AND fiber. If you are not having bowel movements (or having bowel movements less than every 3 days), your bowel movements are hard, you have to strain with bowel movements, and / or your bowel movements are small  pebbles - YOU ARE CONSTIPATED. 
  • Start with 200 mg Colace twice a day and fiber. Make sure that you are drinking at least 64 ounces of non-caffeinated liquids daily.
    • If that does not work then ADD Miralax 1-3 times a day.
    • If that does not work, then ADD one dose of magnesium citrate or milk of magnesia.

• If you have not had a bowel movement by the morning of the fourth day following surgery, drink one bottle of citrate of magnesium, which can be purchased at any pharmacy. Following the first bowel movement, you should have a bowel movement at least every other day. If 2 days pass without a bowel movement, take an ounce of milk of magnesia. Repeat in 6 hours if no result.

• The use of dry toilet tissue should be avoided. After bowel movements use a wet Kleenex, cotton or Tuck’s pads to clean yourself, or if possible, take a warm bath.

• Eat a regular diet including plenty of fresh fruit and vegetables. Drink 6-8 glasses of water a day.

When Should I call the Physician? 

• Diarrhea: Occasional loose bowel movements are not uncommon. However, constant watery diarrhea, especially with fever, can mean there is an infection of the bowels. 
• If you do not have a bowel movement for 3 days despite doing all of the recommended steps (Colace AND Miralax AND fiber AND water AND magnesium citrate or milk of magnesia).
• Inability to drink liquids due to nausea 
• Fever with or without cough (temperature of at least 101.4F): This could be a sign of lung, wound or stomach infection. Elevated heart rate: If your heart rate is more than 100 beats per minute, this could be a sign of infection.
• Sudden shortness of breath and/or chest pain: This could be related to a heart problem, such as a heart attack, or could be related to a blood clot to the lung (pulmonary embolus) or a lung infection. 
• Leg swelling and pain: Blood clot formation in the leg, particularly if it is on one side, could cause swelling with pain in the calf. 
• Passing out: This could be a sign of low blood pressure, which could be caused by blood loss, low blood sugar or other causes. 
• UNABLE TO URINATE WITHIN 8 HOURS AFTER YOUR SURGERY
• If you are concerned, then call. It is better to catch any problem earlier rather than later.

MEDICATIONS that you MAY be recommended to take (please check with your doctor before taking them):

Ibuprofen: Take 1 tablet every 8 hours with food or milk for 1 week. After 1 week take 1 tablet every 8 hours with food or milk as needed for pain.

Tylenol 500mg: Take 2 tablets every 6 hours for 1 week. After 1 week, take 1-2 tablets as needed for pain every 6 hours.

Colace 100mg: Take 2 tablets twice a day to prevent constipation. If you have loose stools take 1 tablet 

Oxycodone 5mg: Take 1-2 tablets every 4-6 hours for pain not controlled by tylenol or motrin.

Miralax: take 1-3 capfuls daily with liquid for constipation. Put the powder in a liquid and mix it. Wait 10 minutes for it to fully dissolve; this will significantly help the taste. Then drink the liquid.
