Excision surgery removes visible endometriosis lesions, but for a meaningful number of patients, pain continues afterward anyway. A systematic review of surgical outcomes found that among women who underwent excision alone, 11.8% reported no improvement in pain, and 22.6% went on to need further surgery.
Dr. Sonia Bahlani, a pelvic pain specialist in New York City who is fellowship-trained in both gynecology and urology, treats these cases as their own diagnostic puzzle rather than assuming the first surgery simply didn't work. Her evaluation asks a more specific question: if the disease was successfully removed, what else could still be generating the pain?
Why Pain Can Persist After Endometriosis Surgery
Pain that persists after excision or ablation usually has a specific driver and is rarely due to leftover disease.
Surgery addresses visible lesions, but several other mechanisms can keep pain active on their own:
- Incomplete excision of deep infiltrating disease in anatomically difficult areas, such as near the bowel or bladder
- Pelvic floor muscle guarding that develops after months or years of pain, and that can outlast the disease that caused it
- Central sensitization, where the nervous system's pain response becomes amplified and persists independent of tissue damage
- Coexisting conditions that mimic recurrence, including interstitial cystitis and pudendal neuralgia
- Adhesions that form during healing from the surgery itself
Research on endometriosis-associated chronic pelvic pain has found widespread myofascial dysfunction and nervous system sensitization in these patients, and notes that this pattern is often unevaluated and unrecognized by the treating clinician.
That distinction between disease that is present and pain generated elsewhere in the system is where treatment plans succeed or stall.
What a Standard Post-Surgical Follow-Up Often Misses
A typical post-operative follow-up only assesses whether the endometriosis comes back. It usually relies on imaging or symptom tracking aimed at anatomical recurrence, which is appropriate as far as it goes.
What it does not routinely include is a pelvic floor muscle exam, a bladder-focused symptom history, or an assessment of nerve involvement. Those are the areas a general OB/GYN or primary care visit is not typically structured to evaluate, and they are frequently where a patient's ongoing pain actually lives.
How Dr. Bahlani Evaluates Pain That Continues After Surgery
Dr. Bahlani's evaluation for a patient with persistent pain after endometriosis surgery starts from a different premise: the surgery may have done exactly what it was supposed to do, and the pain may still need a separate explanation.
Her exam moves beyond a standard post-operative check to include:
- A pelvic floor muscle assessment, since guarding and trigger points are easy to miss without hands-on evaluation
- A bladder-specific history, since interstitial cystitis and endometriosis frequently overlap and are often mistaken for one another
- A review of symptom timing and character, since when and how the pain shows up carries its own diagnostic weight
Symptom timing carries as much diagnostic weight as the exam itself. Patients referred after a surgery that did not fully resolve their pain tend to share a few recognizable patterns:
- Pain that used to track closely with the menstrual cycle becomes present on most days
- Bladder urgency or frequency appears or worsens after surgery, even when the surgical report shows a clean excision
- Pain during sex persists despite imaging that looks unremarkable
None of these patterns means the original surgery was performed poorly, nor does it mean the pain is not real. They point toward a pain generator that has likely moved to muscle, nerve, or bladder tissue, which is why a musculoskeletal and neurologic evaluation needs to happen alongside the gynecologic one rather than after it.
When Repeat Surgery Helps and When It Won't
Repeat surgery has a legitimate role when there is confirmed anatomical recurrence, and Dr. Bahlani will recommend it when the evaluation supports that conclusion. What repeat surgery will not do is resolve pain that is being driven by pelvic floor muscle dysfunction or a sensitized nervous system, since there is no lesion for a surgeon to remove.
This is why a comprehensive evaluation comes before any recommendation for further surgery. Operating again on a patient whose pain is myofascial or neuropathic in origin does not address the source, and it exposes her to surgical risk without a clear path to relief.
A Second Evaluation Can Find What the First Surgery Didn't Address
Pain that continues after endometriosis surgery deserves a fresh, thorough evaluation rather than an assumption that the same treatment approach will eventually work.
For patients whose persistent pain is muscular or nerve-driven, Dr. Bahlani offers a range of procedural options tailored to what her evaluation finds. Trigger point injections target specific areas of pelvic floor muscle guarding directly. BOTOX injections for pelvic floor dysfunction can reduce chronic muscle spasm that continues to generate pain long after the underlying endometriosis has been treated.
These options are not applied as a standard protocol. They are selected based on where a given patient's pain actually originates, often alongside a referral for pelvic floor physical therapy, so the full picture of what is driving the pain is addressed rather than just the piece that shows up on imaging.
Dr. Sonia Bahlani's dual training in gynecology and urology allows her to look beyond recurrence and identify what is actually generating a patient's ongoing pain. If surgery didn't resolve your pain, schedule a consultation with Dr. Bahlani at Pelvic Pain Doc in New York City to start a full evaluation.
