Quick Insights
The LIFT (Ligation of Intersphincteric Fistula Tract) procedure is a sphincter-sparing surgical technique designed to treat anal fistulas while preserving bowel control. Unlike traditional fistula surgery that cuts through sphincter muscle, LIFT accesses and closes the fistula tract through the space between the sphincter layers. Research suggests moderate to high healing rates with minimal short-term impact on continence, though outcomes vary based on fistula complexity, individual anatomy, and length of follow-up.
Key Takeaways
- LIFT is a sphincter-preserving technique that treats anal fistulas without cutting through the muscles that control bowel movements.
- Pooled studies indicate success rates around 76%, with low rates of postoperative fecal incontinence in short-term follow-up.
- The procedure is performed as an outpatient surgery, with most patients returning to normal activities within two to four weeks.
- Long-term data suggest that healing can be lower than short-term estimates and that some patients may develop new or worsened continence symptoms over time, so ongoing monitoring matters.
Why It Matters
For active adults managing anal fistula symptoms while balancing demanding careers and family responsibilities, finding a surgical solution that resolves the problem without compromising quality of life is essential. Persistent drainage, recurring infections, and chronic discomfort can interfere with exercise, work, and daily activities. In my practice, I often see patients who put off fistula surgery for years because they fear losing bowel control. LIFT was developed precisely to address that concern, and understanding what the research actually shows helps patients make informed decisions about their care.
Understanding the LIFT Procedure for Anal Fistula Surgery
Anal fistulas are more than just uncomfortable. They are persistent, often embarrassing conditions that rarely resolve on their own and can significantly affect daily life. Traditional fistula surgery has been effective for many patients, but it often required cutting through sphincter muscle, which raised the risk of bowel-control problems afterward. The Ligation of Intersphincteric Fistula Tract procedure, commonly called LIFT, was developed as a sphincter-sparing alternative.
As a board-certified general and colorectal surgeon and a Fellow of the American College of Surgeons and the American Society of Colon and Rectal Surgeons, I trained specifically in advanced anorectal techniques like LIFT. I previously taught surgical residents at UT Health Houston before opening my private practice and bringing that same academic-level approach to a community setting. You can read more about my background on my physician bio page.
In this article, I explain how LIFT works, what the research actually shows about healing and continence outcomes (including the long-term picture, which is more nuanced than the short-term data suggests), what recovery typically looks like, and how to think about whether this is the right approach for you.
Important Safety Information
LIFT is most appropriate for cryptoglandular anal fistulas, the type caused by infected anal glands, particularly trans-sphincteric fistulas. It may not be suitable for every patient, especially those with Crohn's disease, radiation-related fistulas, or complex recurrent tracts. Patients with an active perianal abscess generally need the infection drained and treated before LIFT can be considered. As with any surgery, there are risks, including bleeding, infection, recurrence of the fistula, and in some cases delayed continence changes. I review each patient's complete medical history, including any inflammatory bowel disease, prior anal surgeries, and continence concerns, before recommending a specific surgical approach.
How the LIFT Procedure Works
Anal fistulas typically begin when an infected anal gland creates a tunnel, called a tract, between the inside of the anal canal and the skin near the anus. Many fistulas pass through or between the sphincter muscles, the rings of muscle that control bowel movements. A traditional fistulotomy opens the entire tract, which can include cutting any sphincter muscle in the way and may compromise continence.
LIFT takes a different approach. I access the fistula tract through the intersphincteric space, the natural plane between the internal and external sphincter muscles, identify the tract, tie it off (ligate it) on both sides, and remove the diseased portion of the tract. Crucially, no sphincter muscle is cut. The structural integrity of the sphincter complex is preserved while the infected channel is eliminated.
LIFT was first described in 2007 by Rojanasakul and colleagues at Chulalongkorn University, who reported primary healing in 17 of 18 patients (94.4%) with no clinical disturbance in continence at early follow-up. The American Society of Colon and Rectal Surgeons describes the LIFT approach in its patient education materials as a non-sphincter-dividing option for appropriate candidates. The procedure is typically performed under anesthesia as an outpatient case, meaning most patients go home the same day.
What the Research Shows: Healing Rates and Continence Outcomes
Success Rates and Healing
When I talk with patients about LIFT, I want them to understand the realistic range of outcomes, not just the best-case numbers. A 2020 systematic review and meta-analysis in Surgery pooled 26 studies covering 1,378 patients and found a weighted mean success rate of about 76%, with a complication rate near 14%. The most common complication was wound dehiscence. Fecal incontinence was reported in roughly 1.4% of cases at short-term follow-up.
Importantly, that same analysis identified three factors statistically associated with treatment failure: horseshoe-shaped fistulas, fistulas associated with Crohn's disease, and a history of prior fistula surgery. In other words, LIFT performs best for straightforward trans-sphincteric cryptoglandular fistulas in patients who have not been previously operated on. Outcomes are less predictable in complex, recurrent, or inflammatory bowel disease cases. Some patients may need a second procedure if the fistula recurs.
Continence Preservation
The main reason patients and surgeons choose LIFT is to protect bowel control. Short-term continence preservation is the strength of the technique, as demonstrated in the original Rojanasakul series and consistently across the published literature.
The long-term picture, however, is more nuanced and important to be honest about. A 2024 long-term cohort study in BJS Open followed 110 patients who had LIFT for trans-sphincteric cryptoglandular fistulas, with a median follow-up of 92 months. Primary fistula healing was 28%, lower than pooled meta-analysis figures. Short-term continence impact was relatively minimal, but long-term incontinence rates reached 74% on standardized questionnaires. Preoperative seton drainage was associated with better healing (33% versus 9%).
What this tells me as a colorectal surgeon is two things. First, LIFT still meaningfully reduces the immediate risk of incontinence compared with sphincter-cutting procedures, which remains its core advantage. Second, long-term monitoring is essential. I encourage my patients to follow up regularly after any anorectal surgery and to report new continence changes, even years out from the original procedure.
Comparing LIFT to Other Approaches
LIFT is one of several options on the spectrum of fistula treatments. Traditional fistulotomy remains highly effective when the involved sphincter muscle is minimal. Seton placement, which uses a soft surgical drain in a staged approach, is another sphincter-sparing option but requires a longer treatment timeline. Advancement flap and fistula plug procedures are additional alternatives.
A 2024 network meta-analysis in the International Journal of Surgery of 28 randomized controlled trials and 2,274 patients compared 13 different surgical techniques for complex anal fistula. The analysis found no statistically significant differences between techniques for overall cure rate or recurrence, but LIFT ranked favorably for the lowest postoperative incontinence at one month. Research into refinements continues. An RCT of 98 patients published in 2021 in Surgery found that adding platelet-rich plasma to the LIFT technique improved short-term healing and lowered postoperative pain compared with standard LIFT, though recurrence at one year was similar between groups.
The choice among techniques depends on fistula anatomy, prior treatments, individual patient priorities, and how I weigh healing rates against continence risk. At Houston Community Surgical, I offer comprehensive colorectal surgery services including the full spectrum of fistula treatments, so the recommendation is always tailored to the specific situation in front of me.
Recovery, Quality of Life, and What Happens After LIFT
Because LIFT does not cut through sphincter muscle, postoperative pain is generally less than with a traditional fistulotomy. Most of my LIFT patients are treated as outpatients and go home the same day. They typically return to desk work within a few days and to most normal activities, including exercise, within two to four weeks.
There is usually some drainage and tenderness in the first one to two weeks. I advise patients to keep the area clean, use sitz baths several times a day, avoid straining, and follow a fiber-supported bowel routine. Follow-up matters. Fistulas can be stubborn, and a meaningful subset of patients require a second intervention. The 2022 American Society of Colon and Rectal Surgeons clinical practice guidelines for anorectal abscess, fistula in ano, and rectovaginal fistula emphasize individualized treatment, multidisciplinary input where appropriate, and a measured role for sphincter-sparing techniques in appropriate candidates.
For patients worried about how surgery will fit into their life, LIFT often offers a workable balance: a definitive treatment plan with a recovery profile that allows most people to resume work, exercise, and family responsibilities relatively quickly, with a meaningfully lower short-term risk of incontinence than sphincter-cutting alternatives. Long-term monitoring remains important, as the data on extended follow-up makes clear.
Anal Fistula Surgery for Houston Heights Patients
Many of the patients I evaluate for anal fistula surgery delay seeking care because they feel embarrassed or worry about how surgery will affect work, exercise, or caring for their families. LIFT directly addresses the continence concern that holds many patients back. My fellowship training in colorectal surgery and experience with advanced minimally invasive techniques means patients have access to the full spectrum of fistula treatments, from conservative management to sphincter-preserving procedures like LIFT, in a community-based setting without the drive into the Medical Center district. Houston is home to the Texas Medical Center, and academic-level surgical training is now available much closer to home for patients across the inner loop.
For patients whose fistula symptoms overlap with bowel-control issues, especially those who have already tried conservative measures, I also evaluate advanced treatment options for continence concerns as part of a comprehensive plan. Same-day and next-day appointments make it easier for busy professionals and parents to be seen quickly. The environment is judgment-free, because anal fistulas are common, treatable, and absolutely nothing to be embarrassed about.
When Should You Talk to a Colorectal Surgeon About Your Symptoms?
I want this to feel like a real conversation, the way I would talk with a patient who has been quietly living with symptoms. Consider scheduling a consultation if you are experiencing persistent drainage near the anus that may be clear, bloody, or contain pus. Other signals include recurrent pain or swelling in the same area (especially if you have had an abscess drained before), a visible opening or lump near the anus that will not heal, or a previously diagnosed fistula that you have not yet treated because you were worried about incontinence or recovery time.
These symptoms can feel embarrassing, and many of my patients wait longer than they should. Fistulas do not resolve on their own. Delaying treatment usually means living with discomfort and recurrent infections that interfere with quality of life. If you have had a fistula repair before and symptoms have returned, that is also a reason to seek a second opinion. The goal of an evaluation is to map your specific anatomy, discuss all your options including sphincter-sparing techniques like LIFT, and build a plan that fits your life and priorities.
What to Expect During Your Visit at Houston Community Surgical
When you arrive at my office on W. 20th Street, we begin with a thorough conversation about your symptoms, medical history, and any prior treatments. I follow that with a focused physical exam to assess the fistula's location and complexity. In many cases, additional imaging such as MRI is recommended to map the tract and plan the best surgical approach.
I will explain your options, including LIFT if appropriate, and walk through what to expect in terms of healing, recovery, and follow-up. If we proceed with surgery, the procedure is typically scheduled as an outpatient case under anesthesia. For patients who are anxious about in-office evaluations or smaller procedures, my office offers nitrous oxide as a comfort option, depending on the procedure and patient needs. After surgery, you receive detailed recovery instructions, a follow-up plan, and direct access to my team if questions come up. Same-day and next-day appointments are available for patients who need to be seen quickly.
Moving Forward With Confidence
Anal fistulas are treatable, and the LIFT procedure offers a sphincter-sparing option that balances effective healing with continence preservation in carefully selected patients. The published literature shows pooled success rates around 76% with low short-term continence impact, and the technique compares favorably with alternative procedures on the early-continence metric. At the same time, long-term outcomes can be more variable, which is why I emphasize individualized planning, honest discussion of risks, and ongoing follow-up.
If you have been living with fistula symptoms, the cost of waiting is usually prolonged discomfort and recurrent infection, not safety. If you're experiencing any of these symptoms, don't wait. Schedule a same-day consultation by calling my Houston office at 832-979-5670 to request a prompt appointment. Not local? I also offer virtual second opinion case reviews at www.2ndscope.com, so no matter where you are, expert help is just a click away.

Frequently Asked Questions
Is the LIFT procedure painful?
Most patients experience less pain with LIFT compared with a traditional fistulotomy because no sphincter muscle is cut. You will receive anesthesia during the procedure, and postoperative discomfort is typically managed with over-the-counter pain relievers and sitz baths. Pain usually improves significantly within the first week.
How long does it take to recover from LIFT surgery?
Most patients return to desk work within a few days and resume normal activities, including exercise, within two to four weeks. You will have some drainage and tenderness initially, but recovery is generally faster than with sphincter-cutting procedures. I give each patient specific activity guidelines based on the details of their case.
What happens if the fistula comes back after LIFT?
Recurrence is possible, and success rates vary with fistula complexity and anatomy. If a fistula recurs, options include a repeat LIFT, an alternative sphincter-sparing technique, or staged procedures like seton placement. I work with each patient to decide on the best next step based on the specific situation, prior treatment history, and individual goals.
