Hysteroscopy is a gynecological procedure performed with the help of a ‘Hysteroscope’(a narrow telescope with light and camera ) to visualise and treat the conditions within the cavity of the Womb (Uterus)
This procedure is commonly performed for the diagnosis and treatment of gynecological problems like –
The hysteroscope is passed into the womb through the vagina and cervix (entrance to the womb), which means no cuts need to be made over the skin.
Hysteroscopy allows for direct visualization of the uterine cavity, enabling gynecologists to identify the exact location and nature of abnormalities like Polyps, Fibroids, adhesions or Growth ( Cancer or noncancer )
Compared to traditional open surgeries, hysteroscopy is a minimally invasive procedure, often performed as an office procedure, an outpatient procedure, or a day care surgery, resulting in less pain, faster recovery, and reduced scarring.
For example, huge submucous Fibroids can be removed by Hysteroscopy in two settings, and that will be an even more minimally invasive procedure than laparoscopy.
Where a doctor uses a tiny hysteroscope of size 2.9 or 1.9 mm to diagnose and treat conditions in OPD settings without any sedation or anaesthesia, and patients can go home immediately like an OPD consultation.
Many hysteroscopies can be performed in an outpatient setting with potential sedation or anaesthesia. Minimizing hospital stays and allowing for quicker return to normal activities.
Hysteroscopy can help identify structural abnormalities in the uterus that may contribute to recurrent miscarriages, and the same may be rectified to prevent further miscarriage.
By addressing uterine issues that may hinder implantation or cause recurrent miscarriages, hysteroscopy can improve the chances of successful conception and pregnancy, especially when combined with IVF.
In some cases, hysteroscopy can be used to treat conditions like Fibroids or polyps that might otherwise require a hysterectomy, potentially preserving the uterus and its related functions.
The ideal time for hysteroscopy is immediately after stopping menstrual bleeding.
To examine the uterine cavity for conditions like post menopausal bleeding, missing thread of IUD, like CuT.
Post menopausal bleeding –
Previously, cancer of the uterus was considered the most common cause for post menopausal bleeding, but with the advancement of Hysteroscopy, it is now clear that a polyp is the most common cause for post menopausal bleeding.
Missing IUCD thread by doing ultrasonography, we can confirm the presence of an IUCD, but with Hysteroscopy, we can diagnose and remove the device in an office Hysteroscopy.
4. Operative Hysteroscopy :
Can be a continuation of diagnostic Hysteroscopy or planned operative Hysteroscopy for conditions like Fibroids, adhesions, septum…
To treat the conditions identified during diagnostic Hysteroscopy or other imaging tests such as USG, MRI etc.
A Hysteroscopy is a simple procedure performed on an outpatient or day-case basis.
A local/general anaesthesia is preferred according to the surgical procedure to be performed.
The procedure usually takes between 5 to 30 minutes.
It again depends on the type and severity of the disease.
While performing Hysteroscopy, normal saline is used as a distension medium. Inspection of the vagina, cervix, cervical canal, and uterine cavity is performed, and if any pathology is noticed can be treated at the same time.
A hysteroscope is inserted into the uterus through the vagina.
Most of the conditions are treated without dilatation of the cervix using five fringe instruments. Sometimes, cervical dilatation may be required to deal with bigger masses(Fibroid) where a resectoscope is required to be introduced through the cervix.
Whereas in operative Hysteroscopy, is performed to treat a condition such as fibroids or polyps, fine surgical instruments can be passed along the hysteroscope.
These are used to cut or burn away the abnormal tissue
Most commonly carried out hysteroscopic procedure.
Polyps are one of the leading causes of infertility, postmenopausal bleeding, and abnormal uterine bleeding
Office hysteroscopy is the best way to diagnose and remove the polyp.
Submucous Fibroids(FIGO type 0,1and 2) are known for causing excessive, heavy, or prolonged menstrual bleeding, intermenstrual bleeding, and pain in the pelvis.
FIGO type 0,1, and to some extent type 2 Fibroids are better removed by Hysteroscopy than by laparoscopy.
Fibroids up to the size of 5 cm can be removed with the help of a saline plasma bipolar resectoscope in one setting.
Intrauterine adhesions are caused after infection, following procedures like D & C, surgical abortion, operative Hysteroscopy, etc.
Adhesions are one of the etiological factors for infertility, Subfertility, and painful periods.
Adhesion bands are released and excised with hysteroscopic scissors Extensive intrauterine adhesions can cause obliteration of the Uterine cavity, leading to cessation or stoppage of menstrual bleeding, and this condition is called Asherman’s syndrome.
Sometimes, Asherman’s syndrome may require multiple settings of hysteroscopic adhesiolysis. To prevent adhesion formation or recurrence of adhesion following operative hysteroscopy, we can use an adhesion barrier inside the uterine cavity.
Any suspicious growth of the endometrium or endocervical canal can be biopsied with a hysteroscopic grasper.
With the added advantage of taking an accurate biopsy from the precise area.
Intrauterine Septum is a common cause for infertility, failure of implantation, Abortion, premature delivery, and undesired outcome during pregnancy. Hysteroscopic septum resection/ excision using scissors gives an excellent outcome in future pregnancies.
Incomplete abortion by surgical method (dilatation and curettage) could be because of abnormal invasion of the placenta. This is an ideal situation to remove and ensure complete removal of tissue under vision with the hysteroscope.
Congenital anomalies are known for infertility and poor pregnancy outcomes. While organ development two horns unite to form a single uterus. Rarely, the fusion may not take place as deceased and result in various congenital anomalies. Hysteroscopic septum resection and unification of the two halves give excellent outcomes during future pregnancy.
Infertility patients diagnosed with Fallopian tube blockage on HSG is subjected to opening the blockage with the help of a technique called proximal tubal cannulation under hysteroscopic guidance and confirmed by laparoscopy in the same setting.
Lateral wall or fundal adhesions inside the uterus could be the reason for infertility or subfertility. Hysteroscopic lateral and fundal metroplasty is a good way to increase the size of the uterine cavity to its normal size and give a desired outcome during pregnancy.
Women with heavy menstrual bleeding with no obvious pathology and not desirous of pregnancy but willing to preserve the uterus are the ideal patients for TCRE. This procedure is carried out under anesthesia with the help of a loop resectoscope, where endometrial lining is removed, and the patient can be discharged on the same day.
This can prevent the removal of the Uterus (Hysterectomy), which is comparatively more invasive than TCRE.
Sub-endometrial cavity or sub-endometrial adenomyoma can be the cause of painful periods (dysmenorrhoea), heavy menstrual bleeding, and infertility. Hysteroscopic removal of the cavity or Adenomyoma gives an excellent outcome with symptom relief and achieving a positive pregnancy.
Foreign bodies like a missing thread of CuT or residual foetal bone are best managed with the help of Hysteroscopy.
Various studies have proved that Infertility patients with poor endometrium and not responding to the medical line of management are best treated with sub-endometrial injection of platelet-rich plasma under hysteroscopic guidance.
A patient can go home soon after an Office Hysteroscopy. Typically, after a brief hospital stay of a few hours after Operative Hysteroscopy under anaesthesia.
Women can usually return to their normal activities later the same day or the following day if no anaesthetic or just a local anaesthetic was used.
If one had a general anaesthetic, one may need to take things easy for a day or two.
Most common organs involved in endometriosis are the outer surface of uterus and surrounding structures like ovaries, fallopian tube, ligament of uterus, pelvic peritoneum (covering of the abdomen), intestine, urinary bladder, ureter. However, endometriosis can affect any organ in the body from brain upto the leg muscles like lungs, liver, spleen, vagina, diaphragm, kidneys, bone, operative scar incisions (scar endometriosis).
