We provide specialized gynaecological keyhole surgery for removal of ovarian cysts, fibroids or entire womb if necessary. This new advanced surgery is done through much smaller wounds of 0.5 to 1 cm, thus reduces postoperative pain and leads to faster recovery. Hysteroscopic surgery is available for treating menstrual or infertility problems.
Endometriosis
Normally tissues that can produce menstrual blood is found only in the cavity of the womb. In endometriosis, these tissues are present elsewhere too in the body, in addition to the womb.These areas would menstruate , producing blood every time when the periods come, which then cause inflammation and scarring.
Endometriosis commonly leads to pain during menses, difficulty to conceive, or chronic pelvic pain etc. Sometimes it can remain silent, and is detected only during medical examination or ultrasound examination.
The regular menstrual blood secreted in the body causes inflammation and pain. The scarring of the neighbouring organs can distort the normal anatomy, causing obstruction eg fallopian tubes. Those present on the ovaries may lead to cyst formation, commonly called chocolate cysts or endometriotic cysts. These changes damage the ovaries, cause pain and lower the fertility rate.
Less commonly, other organs such as the rectum, colon and bladder etc. may be involved too, resulting in significant problems.
The actual prevalence of the disease is unclear, but among 20-30% of infertile women and 30-40% of women with severe pelvic pain may harbor this condition.
The treatment usually involves two approach, depends on the severity of the disease and the symptoms. Medical therapy, usually involving hormonal suppression, is used for milder cases or to supplement surgery. Operation may be need in the presence of big cyst, severe pain etc.
Ovarian Cysts
A cyst simply means a collection of fluid. As most of the tumours formed in the ovary tend to contain fluid, it is commonly and popularly referred to as “ovarian cyst”.
Fortunately, the non-cancerous types are most common, and they can be further classified according to its content and origin eg dermoid cyst (that may contain hairs, oils, bones, tooth etc), endometriotic or chocolate cyst, mucinous cyst etc. The cancerous form tends to occur in the extremes of age, prepubertal or adolescent, and the postmenopausal.
Some cysts, especially bigger ones, produce pain or pressure symptoms eg pressing on the bladder causing difficulty to hold your urine. The pain associated may be intermittent in nature, worsened during menses or occasionally, very severe and acute. The latter happens when the cyst ruptures or undergoes torsion. Torsion of the ovary is an emergency, not only it causes immense pain, but you may lose the entire ovary as the blood supply is disrupted.
It is not uncommon too to have “silent” cyst i.e. one that does not produce any symptoms, and is detected only at some routine gynaecological examination, or health screening. Ultrasound examination is by far the most important and useful tool for the detection of ovarian cyst.
The most important issues are the nature and size of the cyst. Cancerous growth is of course harmful, and urgent treatment is needed.
Non-cancerous cyst tends to cause pain or discomfort when it reaches certain size. If it grows too big, the remaining healthy ovarian tissue may be destroyed. Some non-cancerous cyst may also affect the menses or fertility potential by interfering with ovarian function.
Not all cysts need to be removed. Some of the smaller cysts are simply physiological and will disappear over 6 8 weeks. Some of the cysts are however pathological and will not disappear but tend to grow with time.
The most important thing is to exclude cancer. A detailed medical history, examination, ultrasound and sometimes blood tests are important preliminary steps. Depending on the information gathered, surgery or just monitoring of the cyst may be recommended.
Presently, video-laparoscopic (or keyhole) surgery is the method of choice for removing most non-cancerous cyst. If cancerous growth is strongly suspected, a laparotomy is then necessary, unless the cancer is still in early stage.
Fibroids
Fibroid is a tumour arising from the muscular wall of the womb. It is one of the most common tumours in human and is estimated to be present in about 20-30% of the women.
Depending on the size and location of the fibroids, there may or may not have any symptoms. Common complaints from fibroids are heavy periods, pain, pressure symptoms on the neighbouring when the fibroid is sizeable. Sometimes it can be associated with recurrent miscarriages and difficulty to conceive. Some of the fibroids produce no symptoms and are detected only at ultrasound or routine gynaecological examination.
Not all fibroids need to be treated. Small fibroids that don’t cause any problems are best left alone. Those that are symptomatic, big, or growing in size need treatments.
Surgery is the mainstay of treatment, either removing the fibroids (myomectomy) or the entire womb (hysterectomy), if the condition is severe. Both of the procedures can be performed either through the key hole technique or video laparoscopy, or the traditional open methods, depending on the doctors’ experience and training.
Medical therapy mainly helps in controlling any heavy bleeding but is unable to shrink the fibroids permanently. Recently other treatment methods involving cutting off the blood supply of the fibroids without removing them are also available, and can be performed either laparoscopically or radiologically.
Infertility
Statistically up to 90% of the normal couple with regular sexual activity would have conceived in 1 year. Therefore, it is time to seek medical attention if you and your partner have been having regular, unprotected sex for one year and there is still no pregnancy.
It is however advisable to see a doctor earlier if you are older than 35 years, or do not experience regular monthly periods, or have previous history of pelvic infection or surgery etc.
The top four causes that may contribute to infertility are ovulation disorders, endometriosis, fallopian tubes obstruction, and sperm problems. They may also coexist, which further hamper fertility. There are also other less common causes like cervical factors, systemic illness, sexual dysfunctions etc.
A detailed medical consultation and examination is necessary, to find out the possible underlying reasons for the difficulty to conceive. Blood tests to measure hormones relevant to reproductive functions and pelvic ultrasound are the initial investigations needed.
A semen analysis is also preferred. Depending on the results, further test may be needed to check for the patency of the fallopian tubes and exclude endometriosis. This may involve a minor day surgery procedure, diagnostic laparoscopy and hydrotubation. Alternatively, a special X ray (HSG) or ultrasound can be arranged to test the fallopian tubes.
Treatment methods are highly tailored to individual needs and the causes of infertility found. In principle, it should start with simpler, cheaper, and safer methods before embarking on the more invasive and expensive ones.
The range of treatment options includes:
Keyhole Surgery
In recent years, there is a strong move in all aspects of surgery to minimize
the trauma and pain of the patients, helping in faster recovery while continuing to achieve the same therapeutic results. This class of surgery is called MINIMALLY INVASIVE SURGERY.
For treating gynaecological diseases, two forms of such surgery are available:
It involves the surgeon inserting a video camera enabled instrument to visualize the body parts of interest eg into the abdominal cavity (laparoscopy) or cavity of the womb (hysteroscopy). Commonly the organs that need to be examined have to be inflated with gas or liquid beforehand.
A few more tiny cuts may be needed, all less than 1cm, to allow more instruments to be inserted for the surgical procedures.
Using laparoscopic surgery, the following can be performed:
On the other hand, hysteroscopy is used to:
The obvious advantages are the smaller wound size (1cm or less), less pain, and faster recovery. Most of the procedures can be
performed in the Day Surgery and the patients can go home on the same day. The risk of infection and adhesions formation are also
lower. Finally the cosmetic effect of the tiny scars is certainly welcomed.
The disadvantages include longer operating time and use of more assistants and instruments which may increase the cost. Most
importantly however, is that it is technically more demanding and the surgeons need proper training and experience to acquire the
necessary skills.
Laparoscopy
Laparosocpy involves passing a lighted video camera (laparoscope) into the abdominal cavity, in order to allow the surgeon to visualize the internal organs, from the womb, ovaries, fallopian tubes to the intestines, gallbladder, liver etc.
This procedure is usually done under general anaesthesia. Carbon dioxide gas is needed to distend the abdominal cavity to allow proper visualization during the operation.
Almost 90% of all gynaecological surgery can be done laparoscopically; the extent is largely dependent on the experience of the surgeon. Through three to four cuts of 0.5-1cm sizes on the belly button and lower half of the tummy, the laparoscope and other instruments are inserted into the abdomen to perform the surgery.
The type of surgeries ranges from tubal sterilization, treatment of endometriosis, infertility tubal surgery, removal of ovarian cysts and fibroids to removal of the entire womb and ovaries.
As the wounds are much smaller when compared to the traditional open method, the recovery tends to be less painful and faster. In addition, the chance of wound infection is also much lower.
Finally, smaller wounds are certainly better for cosmesis, ie the appearance of the patient.
Hysteroscopy
Hysteroscopy refers to visualization of the cavity of the womb using a hysteroscope (a telescope with light).
The cavity is usually filled with either gas or fluid first eg water, normal saline etc to facilitate proper viewing. A diagnostic hysteroscopy can be performed under local anesthesia if needed to.
Common reasons that hysteroscopy is necessary include investigations for abnormal menses, infertility, repeated miscarriages, as well as the treatment for certain diseases.
Hysteroscopic surgery can be used to remove polyps or fibroids that grow into the cavity of the womb (submucous fibroids), reduce heavy menses, remove foreign bodies, adhesions etc. These operations may be performed under general or regional anesthesia, and commonly as day surgery procedures.
Hysteroscopic surgery is the least invasive gynaecological surgery. As the entire procedure is performed via the vagina, there is no abdominal wound.
Recovery is very fast and pain is minimal. It should be the first option of treatment if the disease and conditions are appropriate.
