Contemporary vaginoplasty (surgical vaginal construction) has undergone considerable technical refinement, with increasing emphasis on functional and naturalistic outcomes. The Free Small Intestinal Jejunal Graft technique constitutes one of the highest-complexity procedures in gender affirmation surgery. This article analyzes the surgical process within the framework of high-level risk management — "The Patient Safety Diamond" — representing an integration of technical precision and patient safety protocols designed to minimize complication rates and maximize graft viability.
1. A Life-Changing Innovation: An In-Depth Examination of the "Free Jejunal Graft" Vaginoplasty Technique
Male-to-female (MTF) gender affirmation surgery represents a pivotal and transformative milestone for transgender individuals. Among the most technically demanding challenges confronting the reconstructive surgeon is the creation of a neovaginal canal that is aesthetically refined, functionally viable, and of adequate depth. Dr. Sanguan Kunaporn, Director of the Phuket Plastic Surgery Institute (PPSI) and a specialist in gender affirmation surgery, has collaborated with his medical team to publish and disseminate a novel technique that has received recognition in international peer-reviewed medical journals — namely, the Free Jejunal Graft technique utilizing an autologous segment of the small intestine.
This technique represents a point of institutional pride for PPSI and constitutes a meaningful contribution to the body of knowledge within the field of plastic and reconstructive surgery. Its salient features and technical distinctions are described in detail herein.
What Is the Free Jejunal Graft Technique?
The Free Jejunal Graft is a surgical innovation in which a segment of the patient's own small intestine (jejunum) is harvested and utilized as the mucosal lining of the newly constructed vaginal canal. This technique was developed to overcome the inherent limitations and disadvantages associated with conventional vaginoplasty methods.
Two-Stage Surgical Method
A defining feature of this technique is its division into two discrete operative stages, designed to optimize patient safety and ensure superior outcomes:
• Stage 1: The surgeon performs orchiectomy (surgical removal of the testes), urethroplasty (urethral reconstruction), and neovaginal canal dissection to prepare the recipient site.
• Stage 2: Either single-port laparoscopy — a minimally invasive approach involving a small incision with minimal tissue disruption — or an open extracorporeal technique (in which intestinal anastomosis is performed outside the abdominal cavity) is employed. A jejunal segment of approximately 15 centimetres in length is harvested, remodelled, and introduced into the prepared neovaginal cavity.
Advantages and Distinguishing Strengths of the Free Jejunal Graft Technique
1. Reduction of Complications and Postoperative Oedema: The two-stage operative strategy affords the surgical team effective intraoperative haemostatic control, substantially reducing postoperative oedema of the neovaginal canal.
2. Safety Profile and Absence of Persistent Gastrointestinal Sequelae: Clinical follow-up data have demonstrated a high safety profile for this technique, with no severe complications reported. Patients have not experienced persistent gastrointestinal discomfort attributable to the jejunal harvest.
3. Optimal Resolution of Vaginal Depth: The use of jejunal tissue for neovaginal lining provides an effective solution to the clinical challenge of achieving adequate vaginal depth, resulting in high levels of patient satisfaction.
4. Natural Endogenous Lubrication: The inherent secretory properties of jejunal mucosa enable autonomous production of mucosal lubricant, substantially reducing or eliminating the need for exogenous lubricants during sexual intercourse.
5. Aesthetic Integration and Natural Appearance: External incisions are designed to be concealed within the natural folds of the labia majora and labia minora, yielding a result that appears unforced and anatomically consistent — enabling patients to engage in daily activities and sexual function with confidence.
Informed by Dr. Kunaporn's extensive clinical experience and the PPSI team's sustained commitment to medical innovation, the Free Jejunal Graft technique has emerged as one of the most efficacious options available, fulfilling both aesthetic and functional objectives, and enabling patients to embark upon their new lives with complete fulfilment.
2. Patient Safety Management: "The Patient Safety Diamond"
Dr. Kunaporn has consistently upheld and integrated patient safety standards in accordance with The Patient Safety Diamond framework of the International Society of Aesthetic Plastic Surgery (ISAPS). This framework constitutes a four-pillar conceptual model of patient safety, designed to mitigate surgical risk and control variables that determine procedural success. The four pillars are as follows:
1. Patient: The patient occupies the central position and constitutes the apex of this conceptual framework, as the individual upon whom all surgical decisions bear the most direct impact. Each patient must undergo comprehensive assessment of both physical and psychological readiness, and must satisfy the eligibility criteria appropriate to the specific procedure under consideration.
2. Procedure: The selected surgical technique must be specifically tailored to the individual patient's anatomical profile and clinical presentation. For example, a patient presenting with mammary ptosis would not be adequately served by augmentation alone; a concurrent mastopexy would be clinically indicated.
3. Surgeon: The operating surgeon must be a board-certified plastic surgeon who has undergone formal, discipline-specific training in plastic, reconstructive, and aesthetic surgery, and holds specialist accreditation from the Medical Council — thereby ensuring the requisite technical proficiency and surgical foundational knowledge.
4. Facility: The surgical facility must meet established accreditation standards (such as JCI or HA certification), maintain rigorous infection control protocols, and ensure a sterile operating environment. For major procedures requiring general anaesthesia, the institution must be supported by a fully equipped multidisciplinary team — including anaesthesiologists and internists — capable of managing the patient's pre-existing conditions and procedural risk factors.
Systematic evaluation of all four pillars prior to any operative decision serves as a comprehensive safety guarantee across every surgical case.
3. Intraoperative Excellence: Standards of Care During Surgery
The inherent complexity of the Free Jejunal Graft procedure necessitates a fully integrated perioperative support infrastructure. The following intraoperative standards are rigorously observed
Surgical Safety Checklist: A strict Time-In and Time-Out protocol is implemented to verify and confirm the operative plan immediately prior to skin incision.
One-to-One Anaesthesia: Each patient receives dedicated one-to-one anaesthetic care, supported by advanced monitoring systems providing continuous measurement of oxygenation and CO₂ levels throughout the procedure, to prevent adverse intraoperative events.
Critical Infrastructure: An intelligent emergency power system with an activation latency of less than 10 seconds ensures the uninterrupted operation of ventilators, surgical lighting, and all essential intraoperative equipment.
4. Complication Management and Continuous Knowledge Development
Dr. Kunaporn places considerable emphasis on systematic knowledge-sharing within the multidisciplinary team. The following mechanism is employed to support ongoing quality improvement:
Monthly Case Review: Regular academic case review meetings are convened monthly to conduct in-depth analysis of treatment outcomes and challenging clinical cases. These sessions serve to ensure the continued and appropriate management of patients who may have experienced postoperative complications or who have not yet achieved satisfactory surgical results.
Conclusion
The Free Small Intestinal Jejunal Graft Vaginoplasty, as developed and performed by Dr. Sanguan Kunaporn at the Phuket Plastic Surgery Institute, represents a significant advance in gender affirmation surgery. By combining the biological advantages of autologous jejunal mucosa with a rigorously staged operative protocol and the comprehensive safety architecture of The Patient Safety Diamond, this technique addresses longstanding functional and aesthetic limitations of conventional vaginoplasty. It stands as a reproducible, patient-centred model for high-complexity reconstructive surgery in the field of gender medicine.
