Rectal prolapse surgery, also known as rectopexy, is performed to correct the condition where the rectum stretches and protrudes out of the anus. The success of these surgical procedures relies heavily on the patient's adherence to post-operative care instructions, with diet playing a crucial role in recovery. This article provides a detailed overview of the dietary considerations and recovery process following rectal prolapse surgery.
Understanding Rectal Prolapse and Surgical Options
Rectal prolapse occurs when the rectum, the final part of the large intestine, loses its support and slips out of the anus. Surgery is often necessary to correct this condition, and the approach can vary depending on the patient's overall health and the extent of the prolapse. Surgical options include:
- Abdominal Procedures: These involve accessing the rectum through an incision in the abdomen.
- Abdominal Rectopexy: The surgeon repositions the rectum and secures it to the sacrum (the back wall of the pelvis) using sutures or a mesh sling. A bowel resection (colectomy) may also be performed to remove part of the large intestine, especially if chronic constipation is present.
- Laparoscopic Rectopexy: This minimally invasive approach uses a laparoscope (a thin tube with a camera) and small abdominal incisions to perform the rectopexy. Bowel resection may also be performed.
- Robotic Rectopexy: Similar to laparoscopic rectopexy, this technique uses a robotic device to aid in the repair.
- Perineal Procedures: These procedures are performed through an incision in the perineal area (the area between the anus and genitals).
- Altemeier Procedure: The prolapsed rectum and a portion of the sigmoid colon are pulled through the anus, removed, and the remaining rectum is reattached to the large intestine. A levatorplasty (tightening of the pelvic floor muscles) may also be performed.
- Delorme’s Procedure: This is typically used for smaller prolapses. The lining of the rectum is removed, and the muscular layer is folded over and stitched together inside the anal canal to create a doubled muscular wall that holds the rectum in place.
Initial Post-Operative Diet
Immediately following surgery, your diet will be carefully managed to allow your digestive system to recover.
- Liquid Diet: Immediately after your operation and once you are awake from the anesthetic, you will be given a liquid meal. If you received a spinal anesthetic without general or intravenous anesthesia, you will be given solid food.
- Advancing the Diet: Once tolerating oral intake of either type, you will be started on fiber supplementation and/or a laxative (if you are a day case, you will take the first dose when you get home). If you are discharged on a liquid diet the day of surgery, advance to solid food by the following morning.
- Low-Residue Diet (If Bowel Resection Performed): If a portion of the intestine or colon was removed (bowel resection), a low-fiber diet is typically recommended for the first 2 weeks.
Dietary Guidelines for Recovery
The primary goal of the post-operative diet is to promote healing, prevent constipation and straining, and minimize irritation to the surgical site.
Foods to Focus On
- Clear Liquids: In the initial days after surgery, a clear liquid diet helps keep you hydrated without putting too much stress on your digestive system.
- Soft Foods: As you progress, soft foods are easier to digest and less likely to cause discomfort. Examples include:
- Cooked vegetables (carrots, corn, potatoes)
- Bananas
- Avocados
- Mashed potatoes
- Tender proteins
- High-Fiber Foods (After Initial Healing): Once your digestive system has recovered, gradually incorporate high-fiber foods to promote regular bowel movements and prevent constipation. Good sources include:
- Whole grains
- Low-acidic fruits and vegetables
- Protein-Rich Foods: Protein is essential for tissue repair and healing. Include sources like:
- Seafood (rich in zinc)
- Almonds (rich in vitamin E)
- Beans (packed with iron)
- Vitamin C Rich Foods: Citrus fruits like lemon, sweet orange and grapefruit are rich in vitamin C, which is known to help in soft tissue and collagen repair.
Foods to Avoid
- Spicy Foods: Avoid spicy foods for at least 2 weeks to minimize anal burning.
- Citrus Fruits: Limit citrus-containing foods like lemons and oranges for 2 weeks for the same reason.
- Chewy or Crunchy Foods: These can be difficult to digest and may irritate the intestines.
- Raw Produce: Uncooked fruits and vegetables are high in fiber and can be hard to digest, especially in the initial recovery period.
- Fatty and Greasy Foods: These can worsen diarrhea, which is a common side effect after bowel resection.
- Beans and Dairy: These can cause gas and bloating, leading to discomfort.
- Caffeinated Drinks: Coffee and soda can stimulate the intestines and lead to diarrhea.
- Alcohol: Alcohol can interfere with pain medications and slow the healing process.
The Importance of Hydration
Staying well-hydrated is crucial for maintaining soft stools and preventing constipation.

- Drink Plenty of Fluids: Aim for water as your primary source of hydration.
- Avoid Sugary Beverages: Limit or avoid soft drinks, alcohol, and sugary beverages.
Medication and Supplements
- Pain Medication: Take pain medications as prescribed by your surgeon. For mild discomfort, Tylenol (paracetamol) can be taken as needed.
- Stool Softeners: Use stool softeners as directed to prevent straining during bowel movements.
- Fiber Supplementation: Fiber supplements can help regulate bowel movements and prevent constipation.
- Laxatives: If you do not have a bowel movement for two days, consider taking a mild laxative like milk of magnesia or Dulcolax, as directed by your doctor.
- Blood Thinners: If you are on any blood thinner, ask Dr. Maher Abbas for specific instructions.
- Anti-Acid Medication: Sometimes you will be prescribed an anti-acid medication to protect your stomach (such as Gaviscon, Zantac, Pepcid, Tagamet, Nexium, Prilosec, Pantazol).
Additional Recovery Tips
- Rest and Activity:
- Take time off from work to allow your body to heal. The duration will depend on the nature of your job.
- Avoid heavy lifting and strenuous activity for at least 6 weeks.
- Limit activities that strain the abdominal muscles, such as sit-ups, sprinting, and sex.
- Wound Care: Keep your wound clean and dry. Follow your surgeon's instructions for wound care, including cleaning with special soap.
- Bowel Habits: Be aware that your bowel habits may vary for a few weeks after surgery. Frequent and/or loose stools are common.
- Hygiene: Avoid toilet paper as it can irritate the skin around the anus.
- Sitz Baths: Sitz baths can help soothe the anal area. Avoid putting salt or scented products in the water until the wound has healed completely.
- Pelvic Floor Exercises: Pranayama, Mula Bandha, and Kegel exercises can help strengthen the pelvic floor muscles and improve recovery.
- Yoga: Vajrasana or The Adamant Pose is a yoga asana that treats and prevents constipation.
- Smoking: Avoid smoking.
Enhanced Recovery After Surgery (ERAS) Protocol
Many patients are enrolled in the Enhanced Recovery After Surgery (ERAS) protocol. ERAS has many proven advantages to the patient including earlier mobilization, faster return of bowel function, and less pain. By the early removal of tubes and catheters, early ambulation, same day feeding, and minimizing the use of opioids pain medications, you will be able to recover much faster.
Potential Risks and Complications
Rectal prolapse surgery carries potential risks, which vary depending on the surgical technique. Recurrence of rectal prolapse after surgery occurs in about 2% to 5% of people.
Long-Term Outlook
For most individuals, rectal prolapse surgery effectively alleviates symptoms and improves fecal incontinence and constipation. However, it is important to note that constipation can worsen or become a new problem for some individuals after surgery.
