A colorectal surgeon is the specialist most directly responsible for diagnosing and treating rectal prolapse. This is the doctor trained specifically in conditions affecting the colon, rectum, and anus, and they perform the vast majority of corrective surgeries for the condition. But rectal prolapse often involves more than the rectum alone, and depending on your age, sex, and whether other pelvic organs are also affected, you may end up seeing a team of specialists rather than just one.
The Colorectal Surgeon Is Your Starting Point
Colorectal surgery is a subspecialty of general surgery. After completing a general surgery residency, these surgeons train for an additional year or more focused exclusively on the lower gastrointestinal tract and pelvic floor. They are the doctors who evaluate the degree of prolapse, determine whether surgery is needed, and perform the operation. For a straightforward case of full-thickness rectal prolapse in an otherwise healthy adult, a colorectal surgeon can manage the entire process from diagnosis through post-operative follow-up.
The reason this specialty takes the lead is that surgery is the only definitive treatment for full-thickness rectal prolapse. Conservative approaches can manage symptoms and slow progression, but they do not fix the underlying problem once the rectum has fully protruded through the anal canal. A colorectal surgeon’s core expertise is choosing between the two broad categories of repair (abdominal and perineal approaches) and performing them safely.
Other Specialists You May See
Rectal prolapse does not always exist in isolation. The pelvic floor is a shared structure, and weakness in one area often means weakness in others. Women with rectal prolapse frequently have concurrent vaginal vault prolapse or bladder prolapse. Rectal and vaginal prolapse have traditionally been treated as separate problems by separate specialists, which often led to frustration and incomplete results. In recent years, there has been a shift toward a more patient-centered, multidisciplinary approach that addresses the whole pelvic floor at once.
Here are the specialists who commonly get involved:
- Urogynecologist: If you also have vaginal prolapse, urinary incontinence, or other pelvic floor problems, a urogynecologist handles the gynecologic side. When both rectal and vaginal prolapse need surgical repair, a combined minimally invasive procedure can address both problems in a single operation, which adds little extra time and spares you a second recovery period.
- Gastroenterologist: Before surgery, a gastroenterologist may evaluate underlying bowel function. They can perform specialized tests like anorectal manometry and help distinguish rectal prolapse from conditions that mimic it, such as internal intussusception or a large rectocele.
- Pelvic floor physiotherapist: These therapists specialize in strengthening the muscles that support the pelvic organs. They often manage biofeedback therapy and guide exercises both before and after surgery.
- Primary care physician: Your family doctor or internist is usually the first person you talk to. They can perform an initial exam, rule out other causes, and refer you to the right specialist.
Why a Multidisciplinary Pelvic Floor Clinic Matters
At larger medical centers, you may be referred to a dedicated pelvic floor clinic where colorectal surgeons, urogynecologists, gastroenterologists, and physiotherapists all work in the same setting. These clinics exist because pelvic floor disorders frequently involve more than one compartment. A patient might come in with rectal prolapse but also have a cystocele or significant urinary symptoms that need attention.
The practical advantage is that you get assessed by multiple specialists in a single visit rather than bouncing between separate appointments over weeks. If your symptoms require different treatment strategies for different problems, the team can discuss priorities together and with you. One study of a multidisciplinary pelvic floor clinic found that about one-fourth of patients ended up having combined surgery to address problems in more than one pelvic compartment, which saved costs and meant only one recovery period.
When both rectal and vaginal prolapse are present, the combined procedure is typically a minimally invasive abdominal approach that includes a sacral colpopexy for the vaginal vault and a ventral rectopexy for the rectum. The choice between an abdominal or perineal approach depends on the patient’s overall health, prior surgeries, feelings about mesh, and the surgeon’s expertise. Surgeons should at minimum be able to identify patients who need this kind of combined repair and refer them to a specialized center if they cannot perform it themselves.
What Happens During Diagnosis
Rectal prolapse can sometimes be diagnosed on a simple physical exam if the prolapse is visible when you bear down. But in many cases, especially with internal prolapse (where the rectum folds inward but hasn’t come all the way out), further testing is needed. Here is what the diagnostic workup can involve.
Defecography is the key imaging test. It involves filling the rectum with contrast material and then taking images while you attempt to evacuate. This can be done with traditional X-ray or with MRI. Both methods perform similarly for detecting problems in the back compartment of the pelvic floor. One study comparing the two techniques found no significant differences between X-ray and MRI defecography for diagnosing rectal prolapse, rectocele, or other posterior compartment abnormalities. MRI has the added benefit of showing all three pelvic compartments without radiation, which makes it especially useful when multi-compartment prolapse is suspected. In that same study, MRI defecography revealed additional diagnoses beyond what clinical examination alone had found in about a third of patients with complex pelvic floor disorders.
Anorectal manometry is another test you might encounter. It measures the pressures inside your rectum and anal canal at rest, during squeezing, and while simulating a bowel movement. This helps the doctor understand how well your sphincter muscles are functioning and whether there is a problem with coordination during defecation. A balloon expulsion test, often done at the same time, checks whether you can push out a small inflated balloon, which helps identify issues with the muscles involved in evacuation.
These tests matter because the results directly influence treatment decisions. A patient with significant sphincter weakness will be managed differently from someone whose sphincter function is intact, and manometry findings help predict whether continence will improve after surgery.
Surgical Approaches and How the Choice Is Made
Surgery for rectal prolapse falls into two broad categories: abdominal procedures (done through the abdomen, increasingly by laparoscopy or robotic assistance) and perineal procedures (done through the area around the anus, without entering the abdomen). The choice between them is one of the most important decisions your surgeon will make, and it depends heavily on your age, fitness level, and other medical conditions.
For a healthy patient, the strong preference is an abdominal approach. In an international survey of surgeons, 90% said they would choose a minimally invasive abdominal approach for a healthy patient. The most popular option was ventral rectopexy, chosen by more than half of respondents. In an older patient with significant medical problems, 81% of surgeons said they would choose a perineal approach instead. Perineal procedures can often be done under spinal or regional anesthesia, avoiding the risks of general anesthesia in frail patients.
There is a longstanding assumption that the perineal approach is inherently safer for high-risk patients, but the picture is more nuanced than it appears. A large analysis using national surgical quality data found that in the highest-risk patients, the mortality rate after perineal procedures was actually about four times higher than after abdominal procedures. The authors suggested that choosing the abdominal approach for higher-risk patients may not be as prohibitive as traditionally thought. This finding does not necessarily mean the perineal approach is more dangerous; it likely reflects the fact that the sickest and frailest patients are channeled toward perineal surgery, skewing the outcomes. Still, it challenged the conventional wisdom that perineal always equals safer.
A separate analysis of elderly patients comparing open abdominal repair, laparoscopic repair, and perineal repair found no significant difference in outcomes among the three approaches after adjusting for other factors. But the perineal approach was associated with a higher composite complication rate. The takeaway is that the decision is not as simple as “old equals perineal, young equals abdominal.” Your surgeon should weigh your specific risk profile, not just your age.
What About Recurrence
Rectal prolapse can come back after surgery regardless of which approach was used. When it does recur, the question of who treats it becomes relevant again, because re-operation carries its own considerations. In one study of patients with recurrent prolapse, about 61% were treated with a perineal approach the second time around, and 39% had an abdominal repair. The perineal redo was faster (about an hour versus an hour and a half) and involved a shorter hospital stay. The re-recurrence rate, however, was similar between the two groups.
If your prolapse recurs, you will likely return to your colorectal surgeon. They will reassess the anatomy and functional status before deciding on the next step. A patient who initially had a perineal repair might be offered an abdominal approach for the redo, or vice versa, depending on what has changed.
Conservative Management and When to Try It
Not everyone with rectal prolapse goes straight to surgery. Early-stage or mild prolapse, internal prolapse that hasn’t progressed to full-thickness, and patients who are not good surgical candidates may all benefit from conservative management first. Current recommendations suggest trying conservative therapies for two to three months before considering surgery if they fail.
Conservative treatment includes dietary changes (aiming for 30 to 40 grams of fiber daily), stool softeners, defecation training, and at least 100 minutes of aerobic exercise per week. Biofeedback therapy, where you learn to coordinate pelvic muscle contraction with rectal emptying using real-time feedback, is another option. These measures do not cure the prolapse, but they can improve quality of life and manage symptoms like constipation and mild incontinence.
Biofeedback has specific limitations worth understanding. It can improve the function of the external anal sphincter, the muscle you can voluntarily squeeze. But a major driver of incontinence in rectal prolapse patients is low resting pressure in the internal sphincter, which is an involuntary muscle that biofeedback cannot train. This is why biofeedback alone often does not fully resolve incontinence, even when patients report some improvement.
A pelvic floor physiotherapist typically delivers biofeedback and supervises exercise programs. Your gastroenterologist or colorectal surgeon will usually coordinate the conservative plan, and a dietitian may get involved for the dietary component.
What Surgery Does for Incontinence and Constipation
Two of the most common symptoms that bring people to a doctor for rectal prolapse are fecal incontinence (leaking stool involuntarily) and constipation (difficulty emptying the bowel). Both can improve with surgery, but the results depend on the type of procedure.
Resection rectopexy, which removes a portion of the sigmoid colon and fixes the rectum in place, has shown good results for both symptoms. In one study, constipation scores dropped significantly within a few months and stayed improved at follow-up. Among patients who had incontinence before surgery, the vast majority experienced improvement. Symptoms like feeling of incomplete evacuation, excessive time on the toilet, and the need for manual assistance all decreased after the procedure.
Older procedures like the Ripstein repair (which wraps a mesh sling around the rectum) are effective at preventing recurrence but carry a meaningful risk of worsening constipation. In one comparison, persistent constipation was much more common after the Ripstein procedure than after resection rectopexy, and some patients developed constipation for the first time after surgery. This is one reason ventral rectopexy and resection rectopexy have become more popular: they appear to produce better functional outcomes, particularly for bowel habit.
These outcome differences are part of why your choice of surgeon matters. A colorectal surgeon who performs a high volume of rectal prolapse repairs will be familiar with the tradeoffs between procedures and can match the operation to your dominant symptoms.
Rectal Prolapse in Children
The type of doctor who manages rectal prolapse in children differs from the adult pathway. A pediatrician or family doctor usually sees the problem first. In children, rectal prolapse is most often noticed by parents and frequently resolves on its own before it can even be confirmed in the office. It should be viewed as a symptom of an underlying condition rather than a standalone disease.
Common underlying causes include chronic constipation, diarrheal illness, parasitic infections, and malnutrition. Because of the strong historical link between rectal prolapse and cystic fibrosis, a sweat chloride test has traditionally been considered mandatory for any child with recurrent prolapse. In the era of universal newborn screening for cystic fibrosis, this test has a low yield, but it may still need to be considered to avoid missing the rare undiagnosed child. One retrospective review found that about 3.5% of patients with cystic fibrosis had rectal prolapse, and about 3.6% of children presenting with rectal prolapse turned out to have cystic fibrosis.
Treatment in children under four is almost always conservative, because spontaneous resolution is common in this age group. Conservative management focuses on treating the underlying cause: resolving constipation, treating infections, and ensuring adequate nutrition. If the prolapse persists, sclerotherapy (injecting an irritant solution around the rectum to create scarring and fixation) is sometimes used before resorting to surgery. A pediatric surgeon handles any operative intervention, and pediatric gastroenterologists may be involved for the underlying workup.
When Rectal Prolapse Becomes an Emergency
Most rectal prolapse is managed electively, meaning you have time to see the right specialist and plan treatment. But in rare cases, the prolapsed rectum becomes incarcerated, meaning it gets stuck outside the body and cannot be pushed back in. This is a surgical emergency because the trapped tissue can lose its blood supply, leading to gangrene and perforation if not treated promptly.
If you find yourself in this situation, the emergency department is the first stop. Emergency physicians will attempt manual reduction, often using sugar applied to the swollen tissue to draw out fluid and reduce swelling enough to push the rectum back in. If that fails, an emergency surgeon (either a general surgeon or colorectal surgeon on call) will take over. In one reported case of failed conservative reduction, the patient underwent an emergency abdominal approach with sigmoid removal and mesh rectopexy. In another case, an emergency perineal approach (Altemeier procedure) was performed under regional anesthesia, followed by a reinforcing suture around the anus (Thiersch procedure) to address significant sphincter weakness.
The choice of emergency procedure depends on bowel viability, the patient’s overall condition, and the surgeon’s experience. The key point is that incarcerated rectal prolapse needs urgent treatment and should not wait for an elective specialist referral.
Geographic Variation in Surgical Preferences
An interesting wrinkle in the “which doctor” question is that what your surgeon recommends may partly depend on where in the world you live. The international survey of rectal prolapse surgery found striking geographic variation in procedure preference. When surgeons were asked which perineal procedure they would choose, 86% of those in Australasia favored one approach (the Delorme procedure), while 86% of those in the Americas favored a different one (the Altemeier procedure). European surgeons fell in between. For abdominal repairs in healthy patients, ventral rectopexy dominated globally, but suture rectopexy was still preferred by about a third of respondents.
This variation reflects differences in surgical training traditions more than differences in evidence. There is no single “best” operation for rectal prolapse, and clinical guidelines have not converged on one recommended procedure. If you are evaluating surgeons, it is reasonable to ask what procedure they prefer, how many they perform per year, and why they recommend a particular approach for your case. A surgeon who can explain the rationale in terms of your specific anatomy and symptoms, rather than defaulting to whatever they were trained to do, is a good sign.
