Assoc. Prof. Dr. Charnjiroj Thiptanakit

Assoc. Prof. Dr. Charnjiroj Thiptanakit (Thai: ชาญจิโรจน์ ทิพย์ธนกิจ) is a colorectal and general surgeon in Bangkok, Thailand, with Thai board diplomas in general surgery and colorectal surgery. Kamol Cosmetic Hospital names him as its consultant in sigmoid colon and peritoneal vaginoplasty, two feminizing genital techniques that take lining tissue from inside the abdomen, and says he strengthens its gender-affirming team in operations that use the sigmoid colon and the peritoneum. The Thai version of his Kamol profile gives the same role: surgeon for creating the vaginal canal with sigmoid colon and peritoneum.

Why is a bowel surgeon listed on a site about cosmetic and gender-affirming surgery? In both techniques, part of the work happens inside the abdomen rather than on the genitals. The sigmoid colon is the S-shaped last stretch of the large bowel, just above the rectum; the peritoneum is the membrane that lines the abdominal cavity. Kamol's directory files Dr. Charnjiroj as a Colorectal Surgeon under general and specialist surgeons, apart from the hospital's plastic surgeons, and his published training contains no plastic surgery. Read his listing in that light. The published description fits the abdominal and bowel side of these operations; no official page we found gives him the construction of the vulva or the overall surgical plan.

Away from Kamol, Bumrungrad International Hospital lists him for colorectal surgery and general surgery at its Colorectal Surgery Center, with the academic rank Associate Professor, Chulalongkorn University. That profile concerns bowel and general surgery only; it does not connect him with gender-affirming surgery.

Key facts

• Surgical field: colorectal and general surgery; Kamol adds an interest in minimally invasive and complex pelvic surgery
• Based in: Bangkok
• Role at Kamol Cosmetic Hospital: consultant in colon (sigmoid) vaginoplasty and peritoneal vaginoplasty
• Clinic at Bumrungrad International Hospital: Colorectal Surgery Center, Building B, 3rd floor
• Society record: Royal College of Surgeons of Thailand, colorectal surgery field
• Languages Bumrungrad lists for him: Thai and English
• Requests: request a consultation; our patient team confirms his availability with the hospital first

Spellings to know if you search for him elsewhere: Thiptanakit (Kamol's heading, Bumrungrad, Chulalongkorn University and PubMed), Thipthanakit (Kamol's body text) and CHARNJIROJ THIPTHANAKIJ (the Royal College of Surgeons of Thailand). All of them refer to one surgeon.

Everything in this section comes from his two hospital profiles; where Kamol or Bumrungrad gives a date, we reproduce it unchanged. The path runs from medicine through general surgery to colorectal surgery, with no plastic surgery step, which matches the role Kamol describes for him.

• M.D., 1998: Faculty of Medicine Siriraj Hospital, Mahidol University (listed by Kamol).
• General surgery residency: Chulalongkorn University, dated 2005–2006 by Kamol.
• Colorectal surgery fellowship: Chulalongkorn University, dated 2006–2007 by Kamol.
• Thai Board of Surgery diploma: dated 2005 by Bumrungrad; Kamol calls the same diploma the Thai Board of General Surgery.
• Thai Board of Colorectal Surgery diploma: dated 2006 by Bumrungrad.

The dates do not line up. Taken literally, the board diplomas (2005 and 2006) would fall before or during the residency and fellowship that Kamol dates 2005–2006 and 2006–2007. One hospital may be giving start years, the other finish years, or a mix; neither says which. We have not altered either set. If exact dates matter to you, ask the hospital to confirm them.

Society listing. Searching the member database of the Royal College of Surgeons of Thailand (RCST) brings up a single matching record, นพ. ชาญจิโรจน์ ทิพย์ธนกิจ / CHARNJIROJ THIPTHANAKIJ, with colorectal surgery as the field. Two other lists did not include him when we checked in September 2026: the online member directory kept by the Society of Plastic and Reconstructive Surgeons of Thailand (ThPRS), consistent with his being a colorectal rather than a plastic surgeon, and the public member list of the Thai Society of Colorectal Surgeons. An absence from a public list only tells you what that list showed on the day.

Licence check still open. The licence can be looked up on the Medical Council of Thailand's public register at checkmd.tmc.or.th, and our patient team can help you confirm it before you travel. If you want to look yourself, the council's doctor check can be searched with his Thai name, ชาญจิโรจน์ ทิพย์ธนกิจ. Our provider research methodology sets out how every profile on this site is sourced and checked.

Kamol Cosmetic Hospital (current). Colorectal Surgeon, and consultant in sigmoid colon and peritoneal vaginoplasty. The hospital's directory places him under general and specialist surgeons, and no start date is published. Kamol lists one other colorectal surgeon, Dr. Kasidin Vitoopinyoparb. Kamol does not say how colon and peritoneal cases are shared between the two, so if it matters to you, ask which of them would join your operation.

Bumrungrad International Hospital (current). Colorectal surgery and general surgery at the Colorectal Surgery Center, Building B, 3rd floor. When we checked, his outpatient hours were shown as Wednesday and Saturday, 08:30–09:00. Hospital timetables are revised often, so rely on our patient team or the hospital for current hours. No start date is published here either.

Chulalongkorn University (current status unclear). Bumrungrad publishes 'Academic Rank: Associate Professor, Chulalongkorn University', and Kamol calls him an Associate Professor in Chulalongkorn's Department of Surgery. The university's own pages are older and use Assistant Professor, both on a March 2018 Faculty of Medicine staff page and on a February 2022 Department of Surgery page. Neither the department's current faculty list (updated May 2026) nor the colorectal unit's members page includes him. We therefore use the rank the hospitals publish without presenting a current full-time university appointment.

Research with his name on it

PubMed lists two papers in *Diseases of the Colon & Rectum* under Thiptanakit C, with the Colorectal Surgery Division, Department of Surgery, Chulalongkorn University as the affiliation. Both concern major pelvic operations, in line with the interest in complex pelvic surgery that Kamol records for him:

• *Urgent Pelvic Exenteration: Should the Indication Be Extended?* (2018, first author)
• *Anatomical Variations of Iliac Vein Tributaries and Their Clinical Implications During Complex Pelvic Surgeries* (2019)

A Chulalongkorn Department of Surgery page under his name adds five papers from 2008 to 2010 on laparoscopic colorectal operations, surgery for sacral tumours and haemorrhoid surgery. One touches the subject of this profile: a 2010 *Journal of the American College of Surgeons* paper describing a sigmoid flap used for perineal and neovaginal reconstruction after rectal cancer surgery with near-total removal of the vagina. That is cancer reconstruction, not gender-affirming surgery, but it involves the same tissue. PubMed indexes those five papers under a different author name, so their link to him rests on the university page alone.

Kamol's profile also says he has published in *Annals of Coloproctology* and the *Singapore Medical Journal* and lectures at laparoscopic surgery masterclasses. It gives no titles, years or organisers, and we could not find those papers in PubMed, so treat them as Kamol's statements.

We list two procedures for Dr. Charnjiroj. Both are documented at Kamol Cosmetic Hospital, both are carried out by a surgical team, and neither is linked to him at Bumrungrad.

Colon (sigmoid) vaginoplasty

Colon (sigmoid) vaginoplasty lines the new vaginal canal with a length of bowel. Our vaginoplasty guide describes it as a technique generally kept for particular circumstances, revision or limited skin among them. In practice it joins an abdominal operation to a genital one, and Kamol names Dr. Charnjiroj, a colorectal surgeon, as its consultant for this technique.

Points that follow from his particular role:

• Division of labour. Ask Kamol who leads your operation overall, which plastic surgeon handles the genital reconstruction, and what Dr. Charnjiroj himself does in theatre. Nothing published answers this.
• Keyhole or open. Minimally invasive and complex pelvic surgery is among his documented interests, but whether your bowel segment is taken laparoscopically or through an open incision is decided after assessment. Ask what is planned for you and why.
• Bowel preparation and recovery. Ask what you must do before surgery to prepare the bowel, when you can eat again afterwards, and which warning signs after discharge call for an immediate call to the team.
• Life with a bowel-lined canal. Ask what dilation, cleansing and long-term follow-up look like for a canal lined with colon rather than skin. Our procedure pages do not cover this yet, and the answer shapes daily life at home.

Peritoneal vaginoplasty

In peritoneal vaginoplasty, peritoneum lines part of the canal, and our vaginoplasty guide adds that the technique is often robotically assisted. Kamol mentions peritoneal vaginoplasty in the same phrase as sigmoid colon vaginoplasty when it describes his consultant role, but it does not say how its team reaches the peritoneum: robotically, laparoscopically or through an open incision. Ask rather than assume.

Worth raising:

• Peritoneum versus skin. How much of your canal would be peritoneum and how much skin, and whether you need hair removal first. Our guide warns that hair can grow from skin used inside the canal, and permanent removal may need several months, so the answer affects your timetable.
• The abdominal side of recovery. How entering the abdomen changes your hospital nights and first weeks compared with a skin-only operation.
• A plan B. What the team would do if the intended technique could not be completed during the operation, agreed with you in advance.

Techniques not listed for him

Penile inversion vaginoplasty, which our guide calls the most established approach, and vulvoplasty, which forms the external genitals with no canal and therefore avoids lifelong dilation, do not appear on his profiles. Those are plastic surgery discussions. At Kamol they belong with the plastic surgeons, whose Chief Plastic Surgeon is Dr. Kamol Pansritum.

Revision after an earlier vaginoplasty

Revision vaginoplasty is not named as an area of expertise on his official profiles, so we leave it out of his procedure list. Revision is, however, one of the situations in which our guide says a colon technique may be considered. If a bowel-based revision is what you are exploring, say so in your request and include your earlier operation notes; Kamol can then tell you whether he would take part.

His colorectal practice

At Bumrungrad his listed specialties are colorectal surgery and general surgery. ThaiCosmeticSurgery.com only handles requests for cosmetic, plastic and gender-affirming surgery, so for colorectal care unrelated to vaginoplasty, contact Bumrungrad yourself.

Seeing a bowel surgeon about vaginoplasty is a different conversation from a plastic surgery consultation. Expect questions about your abdomen: past operations, digestive health, and whether the tissue a technique depends on is usable in your case. Writing your questions down beforehand helps, and the list below is built around his documented role.

Roles and contact

• Who is the lead surgeon for my operation, and which steps will Dr. Charnjiroj carry out?
• Will I see him before surgery day, in person or by video? Kamol advertises secure video consultations with its surgeons for people who cannot travel yet; whether he joins them is not stated.
• If I have a bowel-related concern on the ward, after discharge or once I am home, whom do I contact?

Choosing the technique

• What makes sigmoid colon or peritoneum the right lining for me, instead of a skin-based technique or vulvoplasty?
• Will the abdominal part be keyhole or open, and what might change that on the day?
• Could previous abdominal or pelvic surgery limit my options?
• How long is my operation expected to take? Our vaginoplasty guide gives 3–6 hours as a common range for vaginoplasty generally; ask what applies to your technique.

Recovery

• How many nights on Kamol's wards should I expect? The common range in our guide for vaginoplasty is 5–7 nights.
• What is the dilation schedule, and for how long will I need it?
• Who clears me to fly home, and roughly when? Our colon and peritoneal vaginoplasty pages give 21–30 days in Thailand as typical.

Complications

For vaginoplasty as a whole, our guide names these possible complications: bleeding, infection, slow or poor wound healing, urinary issues, a canal that narrows or loses depth, altered sensation and a rectovaginal fistula, which is rare but serious (an abnormal passage between bowel and vagina). Because a bowel surgeon is part of this team, ask specifically how a bowel complication would be detected and managed while you are in Bangkok and after you return home, and request complication and revision figures for the technique proposed for you. No outcome data for Dr. Charnjiroj are published.

Eligibility

Thai surgeons generally follow WPATH's SOC-8 (Standards of Care, Version 8). Our vaginoplasty guide summarises what genital surgery usually requires: an assessment documented by a qualified professional, capacity to consent, physical and mental health that is reasonably well controlled and, where clinically appropriate and wanted, hormone therapy, with SOC-8 suggesting a minimum of six months. A number of Thai surgeons still want two letters. Get Kamol's exact requirements before you book travel.

His two hospitals serve different purposes for an overseas patient, and they sit in different districts: Kamol in Wang Thonglang, Bumrungrad in Watthana. A consultation at one does not lead to surgery at the other.

Kamol Cosmetic Hospital, where his vaginoplasty role is documented

Kamol's address is 1223 Lat Phrao 94, Inthraphon Rd., Wang Thonglang, Bangkok 10310; showing a driver the Thai name, โรงพยาบาลศัลยกรรมตกแต่งกมล, helps. At our September 2026 check, Joint Commission International's directory showed Kamol as accredited; the HA Thailand database had no entry for it.

For an operation with an abdominal stage, these details from Kamol's own facilities pages are the relevant ones: a 4th-floor operating floor with a microsurgery theatre and an endoscopic operating suite (the Thai facilities page counts seven operating rooms), an adjoining recovery room of 11 monitored beds, and a wellness and diagnostic centre on the 2nd floor offering in-house lab tests, X-ray, ultrasound, ECG and cardiac stress tests. Private ward rooms occupy floors 5 and 6, with medical residence apartments on floor 7.

After the ward, Kamol moves patients to K Garden, serviced apartments near the hospital, where wound care, removal of stitches and surgeon follow-up continue. For male-to-female genital surgery, Kamol says specialist nurses handle dressings and dilation twice daily there. Ask whether that routine differs for a bowel-lined canal.

On coordination, each request gets a personal representative, an international phone line takes questions and urgent calls, and staff work in English and Thai with interpreters for other languages on request. Kamol also helps with hotels and airport transfers, sends a limousine for your departure, can extend a medical treatment visa, and takes payment by card, bank transfer or cash in baht, euros, US, Australian or Canadian dollars, or pounds sterling.

Bumrungrad International Hospital, his colorectal practice

Bumrungrad is at 33 Sukhumvit 3 (Soi Nana Nua), Watthana, Bangkok 10110, and his clinic is the Colorectal Surgery Center in Building B, 3rd floor. Its accreditations, each confirmed on the accreditor's own directory, are JCI (Hospital Program), HA Thailand advanced re-accreditation running to May 2029, and Global Healthcare Accreditation. International patients can use the Medical Coordination Office (Building A, 10th floor), interpreters (over 130, according to the hospital's factsheet), an airport desk at Suvarnabhumi, complimentary shuttle vans linking the hospital with the BTS Nana and Phrom Phong stations, and help with visas, embassies and insurers.

The gender-affirming surgery page of Bumrungrad's Pride Clinic includes a colon graft among its vaginoplasty techniques, but Dr. Charnjiroj is not among the surgeons that page names, and his Bumrungrad profile is limited to colorectal and general surgery. For colon or peritoneal vaginoplasty with him, Kamol is the documented route.

Planning the trip

Our colon and peritoneal vaginoplasty pages give 21–30 days in Thailand as typical. Keep your return date open-ended if you can: recovery differs between patients, and the surgical team decides when you may travel. Before leaving, ask for English-language operation notes that record the technique and exactly what was done inside the abdomen, so doctors at home can take over your follow-up.

With these two techniques, your records say more than photographs do. Gather the following and send it when our patient team asks, using the channel they give you.

Abdomen and bowel (the part closest to his role)

• Every past operation on the abdomen or pelvis, keyhole procedures included, with the year and any operation notes.
• Bowel diagnoses, reports from any colonoscopy or other bowel tests you have already had, and current digestive symptoms.
• Hernias, past abdominal infections, or radiotherapy to the pelvis.

Gender-affirming care

• Your assessment letter or letters. Our vaginoplasty guide summarises the SOC-8 approach, and Kamol will set out its own requirements.
• Hormone therapy: the medicines, the start date and the prescriber.
• Genital hair removal done so far, since skin placed in the canal can grow hair.

Revision requests

• Notes from the earlier vaginoplasty: technique, date, hospital, and the problem you want corrected, for example lost depth or narrowing.

General health

• Medicines and supplements, allergies, any past problem with anaesthesia, and smoking status.
• Heart, lung, clotting or diabetes history and any recent blood results. Expect pre-operative tests in Bangkok as well.

Logistics

• Possible dates and the longest stay you can manage.
• Whether someone will travel with you.
• Your language, if you need interpretation beyond English and Thai.

About photographs

For bowel- and peritoneum-based techniques, examination and history carry the decision. Intimate images are not needed for a first request. If the hospital later wants them, use the secure route it provides, never ordinary email or chat.
