Presacral Neurectomy in India and UAE | Complete Patient Guide

• ELIGIBLE CANDIDATES:

• Women with chronic, disabling midline pelvic pain (dysmenorrhea or dyspareunia) of at least 6 months' duration despite adequate first- and second-line medical therapy (NSAIDs, combined oral contraceptive pills, progestin-only agents, or GnRH analogs)

• Histologically or laparoscopically confirmed endometriosis (ASRM stage II–IV) with documented central pelvic pain distribution

• Primary dysmenorrhea refractory to at least two different classes of pharmacological agents

• Adenomyosis with predominant midline pain where uterine-sparing surgery is desired

• Patients who have completed childbearing or who are willing to accept the small risk of bladder dysfunction and constipation associated with sympathetic denervation

• Pain predominantly midline and below the umbilicus (VAS score ≥ 7/10); the lateralization of pain is a key selection criterion assessed by the McGill Pain Questionnaire and a structured pelvic pain mapping consultation

• REQUIRED DIAGNOSTIC WORKUP BEFORE SURGERY:

• Transvaginal ultrasound (TVUS) to map endometriomas, adenomyosis, and uterine structural pathology

• High-resolution pelvic MRI (3T preferred) with T2-weighted and diffusion-weighted sequences to characterize deep infiltrating endometriosis (DIE) and assess proximity to the rectosigmoid, ureters, and sacral plexus

• Diagnostic laparoscopy with or without chromopertubation to confirm disease staging and fertility status

• Serum CA-125 (not diagnostic but useful for disease monitoring)

• Urodynamic studies if bladder symptoms are present preoperatively

• Psychological assessment using validated tools (e.g., Hospital Anxiety and Depression Scale — HADS) given the high prevalence of central sensitization in chronic pelvic pain patients

• Preoperative bowel preparation and ureteral stenting consideration for cases involving concomitant rectosigmoid or ureteral endometriosis

• CONTRAINDICATIONS:

• Predominantly lateral or adnexal pain (not amenable to PSN; requires adnexal nerve pathway surgery)

• Active pelvic inflammatory disease or undrained pelvic abscess

• Uncorrected coagulopathy or active anticoagulation that cannot be bridged perioperatively

• Severe retroperitoneal fibrosis from prior surgery or radiation, making safe dissection near the aortic bifurcation and middle sacral vessels prohibitively hazardous

• Patients with pre-existing neurogenic bladder, significant constipation requiring ongoing laxative therapy, or Raynaud's phenomenon (sympathetic denervation may worsen vasomotor instability)

• Pregnancy or active desire for immediate conception without understanding of the small risk of preterm labor related to cervical incompetence (a rare but documented sequela)

• Patients with purely psychosomatic or central sensitization pain without identifiable peripheral pathology are not ideal candidates and should be referred for multidisciplinary pain psychology management first

LAPAROSCOPIC PRESACRAL NEURECTOMY (STANDARD MINIMALLY INVASIVE APPROACH)

Laparoscopic PSN is the current gold-standard technique and the most widely performed approach at centers of excellence in India and the UAE. The procedure is performed under general anesthesia in steep Trendelenburg position. Four laparoscopic ports (one 10–12 mm umbilical and three 5 mm ancillary) are placed. The surgeon opens the posterior peritoneum overlying the sacral promontory and identifies the boundaries of the superior hypogastric plexus: medially by the aortic bifurcation, laterally by the common iliac vessels and ureters, and inferiorly by the first sacral nerve root. The nerve plexus — typically a 2–4 cm wide, dense fibro-neural bundle — is dissected using bipolar energy (LigaSure or PK Dissecting Forceps) combined with sharp scissors, taking particular care to identify and preserve the right ureter and middle sacral vessels. A 2–3 cm segment of the plexus is excised and sent for histopathological confirmation of neural tissue. Hemostasis is achieved with bipolar coagulation. Total operative time ranges from 90 to 150 minutes when performed concomitantly with excision of endometriotic lesions.

ROBOTIC-ASSISTED PRESACRAL NEURECTOMY (ADVANCED APPROACH)

At premium centers in Chennai, Mumbai, Delhi, Dubai, and Abu Dhabi, robotic-assisted PSN using the da Vinci Xi or Si system is increasingly preferred, particularly when concomitant complex procedures such as rectosigmoid nodule excision, ureterolysis, or radical cystectomy for bladder endometriosis are required. The wristed instrumentation of the robotic platform provides 7 degrees of freedom and 10× magnification with three-dimensional visualization, enabling more precise dissection in the narrow retroperitoneal corridor adjacent to the sacral promontory. The risk of inadvertent injury to the middle sacral artery and vein — the most feared intraoperative hemorrhagic complication — is reduced with robotic tremor filtration and enhanced depth perception. Studies in high-volume robotic gynecology programs show a conversion-to-laparotomy rate below 1% for robotic PSN versus 2–4% for conventional laparoscopy.

CONCOMITANT PROCEDURES (FREQUENTLY PERFORMED SIMULTANEOUSLY)

Isolated PSN is rarely performed as a standalone operation. Surgeons at GAF Healthcare's partner institutions typically combine PSN with:

• Complete excision (not fulguration) of endometriotic implants using CO2 laser or ultrasonic energy (Harmonic Scalpel / THUNDERBEAT)

• Laparoscopic ovarian cystectomy for endometriomas > 3 cm

• Uterosacral ligament resection for deep infiltrating endometriosis

• Laparoscopic uterine nerve ablation (LUNA) — though LUNA alone has largely fallen out of favor given RCT evidence showing no additive benefit over excision surgery without PSN

• Adhesiolysis and restoration of normal pelvic anatomy

OPEN PRESACRAL NEURECTOMY (RARELY INDICATED)

Open (laparotomy-based) PSN is reserved for cases with severe retroperitoneal fibrosis from prior surgeries, failed laparoscopic access, or concurrent major bowel resection requiring open anastomosis. It involves a midline or Pfannenstiel incision and direct retroperitoneal dissection. Hospital stay extends to 5–7 days and recovery to 4–6 weeks. This approach is uncommon at centers offering robotic and advanced laparoscopic platforms.

MEDICAL (NON-SURGICAL) ALTERNATIVES CONSIDERED BEFORE PSN

Patients who do not yet meet the surgical threshold, or who wish to defer surgery, may be managed with:

• Continuous combined oral contraceptive pills (monophasic, low estrogen) to suppress cyclical bleeding

• Levonorgestrel-releasing intrauterine system (Mirena IUD 52 mg) — first-line long-acting option

• Dienogest 2 mg daily — the preferred oral progestin for endometriosis pain in most European and Asian guidelines

• GnRH agonists (leuprolide, triptorelin, buserelin) with add-back estrogen-progestogen therapy to mitigate bone loss during prolonged use

• GnRH antagonists (elagolix/relugolix) — newer oral agents providing rapid, reversible suppression without the initial flare associated with GnRH agonists

• Multidisciplinary pain management including pelvic floor physiotherapy, cognitive behavioral therapy (CBT), and low-dose amitriptyline or duloxetine for central sensitization

PHASE 1 — REMOTE CONSULTATION AND PRE-ARRIVAL PLANNING (4–6 weeks before travel)

• Submit medical records (operative reports, MRI/ultrasound images, pain diaries, prior treatment history) through GAF Healthcare's secure patient portal for review by the assigned gynecologic surgeon

• Virtual teleconsultation with the operating surgeon and pain specialist to confirm candidacy, review imaging, finalize surgical plan, and discuss concomitant procedures

• GAF Healthcare coordinator initiates e-Medical visa application for India (typically processed in 3–5 business days) or confirms UAE visa status for patients from eligible countries

• Preoperative hormonal preparation: surgeon may advise a 3-month course of GnRH agonist therapy to reduce pelvic vascularity and inflammation before complex endometriosis excision, or may schedule surgery without pretreatment for simpler cases

• Arrange international travel, accommodation for patient and one attendant, and airport transfer through GAF Healthcare logistics team

PHASE 2 — ARRIVAL AND PREOPERATIVE ASSESSMENT (Days 1–2)

• Day 1: Airport pickup in dedicated GAF Healthcare vehicle; check-in at partner hospital or nearby serviced apartment

• Day 2: In-person preoperative evaluation including repeat pelvic examination, review of imaging, anesthesia consultation (ASA classification, airway assessment, VTE risk stratification using Caprini Score), blood investigations (CBC, coagulation profile, renal and liver function, cross-match), urinalysis, ECG, and chest X-ray

• Bowel preparation with polyethylene glycol solution initiated the evening before surgery for cases involving potential bowel work

• Ureteral stents placed by urology team on the morning of surgery if MRI suggests proximity of DIE to ureters

• Thromboprophylaxis: LMWH (enoxaparin) initiated preoperatively per institutional VTE protocol; compression stockings applied

PHASE 3 — SURGICAL DAY (Day 3)

• Fasting from midnight; admission to pre-operative holding area at 06:00 hrs

• General anesthesia induction with TIVA (total intravenous anesthesia using propofol/remifentanil) or balanced inhalational anesthesia; LMA or endotracheal intubation depending on case complexity

• Patient positioned in steep Trendelenburg (30°); pneumoperitoneum established with Veress needle technique to 12–15 mmHg CO2

• Laparoscopic or robotic port placement; systematic inspection of entire peritoneal cavity and pelvis

• Sequential performance of concomitant procedures (endometriosis excision, cystectomy, adhesiolysis) followed by posterior peritoneal opening and retroperitoneal dissection for PSN

• Nerve segment excised and labeled for histopathology; hemostasis confirmed; port sites closed; total operative time 90–180 minutes depending on complexity

• Post-anesthesia care unit (PACU) observation for 2–3 hours; IV ketorolac, ondansetron, and low-dose opioid PRN for pain and nausea management

PHASE 4 — INPATIENT RECOVERY (Days 3–5)

• Day 3 (evening post-op): Clear liquids commenced; early ambulation encouraged within 4–6 hours of anesthesia clearance per Enhanced Recovery After Surgery (ERAS) gynecology protocol

• Day 4: Light diet; Foley catheter removal; first bowel function assessment (mild constipation expected and normal due to sympathetic denervation — managed with oral lactulose or bisacodyl)

• Day 5 (or Day 3 for uncomplicated cases): Discharge with written wound care instructions, prescribed analgesics (oral ibuprofen 400 mg TDS + paracetamol 500 mg QDS), laxative regimen, VTE prophylaxis (LMWH for 14 days post-discharge per NICE TE7 guidance), and follow-up appointments

PHASE 5 — OUTPATIENT RECOVERY IN COUNTRY (Weeks 1–3)

• Patient remains in India or UAE for a minimum of 2 weeks post-discharge for surveillance and wound check

• Week 1 post-op: Rest; short walks; avoid lifting > 5 kg; laparoscopic port site wound check at Day 7 — surgeon reviews healing and removes any non-absorbable sutures

• Week 2 post-op: Increasing mobility; most patients resume light computer/desk work; pelvic floor physiotherapy assessment initiated if pre-existing pelvic floor tension is identified

• Week 3 post-op: Fit-to-fly assessment by surgeon — confirms absence of fever, port site healing, normal bowel and bladder function, and absence of VTE symptoms before clearing international travel

• Long-haul flights recommended with compression stockings, adequate hydration, and continued LMWH if flight > 4 hours

PHASE 6 — LONG-TERM FOLLOW-UP (Months 1–6)

• Pain reassessment at 1, 3, and 6 months using VAS and Numerical Rating Scale (NRS)

• Hormonal suppression therapy (dienogest or LNG-IUD) typically commenced at the 6-week visit to reduce endometriosis recurrence risk

• Pelvic MRI at 6 months to assess surgical outcome and residual disease

• GAF Healthcare facilitates telemedicine follow-up with the operating surgeon throughout this period at no additional charge
