? Subcutaneous scar endometriosis.

DIFFERENTIAL DIAGNOSIS : 

SCAR ENDOMETRIOSIS

STITCH GRANULOMA DESMOND TUMOUR HEMATOMA NEUROMA

Final Diagnosis:

P2L2 with scar endometriosis with previous 2 LSCS

Excision of scar endometriosis

Endometriosis is a benign disease, defined as presence of ectopic (outside the uterus ) endometrial gland and stroma.

Risk factors:

Previous LSCS /late marriages/ late child birth / genital tract obstruction / frequent and prolonged menstrual cycles / nulliparity / early menarche

Theories of sites of endometriosis: 1. Pelvic endometriosis- Retrograde metaplasia

2. Abdominal viscera – coelomic metaplasia 3.Pelvic peritoneum- coelomic metaplasia 4.Rectovaginal septum – coelomic metaplasia 5.umbilicus – coelomic metaplasia

  1. Abdomen scar – direct implantation
  2. Episiotomy scar – direct implantation
  3. Vagina and cervix – direct implantation
  4. Lymph nodes – Lymphatic spread
  5. Other- vascular genetic immunologic

SCAR ENDOMETRIOSIS

Scar endometriosis is a rare entity reported in gynaecology literature and presents in women who has undergone previous abdomen or pelvic surgeries . It is defined by the implantation or/and growth of endometrial tissue postsurgically at the incision site. Most commonly accepted theory for scar endometriosis is Direct endometrial implantation to wound edge during abdominal or pelvic surgeries.

The incidence of scar endometriosis has been shown to be less than 2%with the most common subtype being post cesarean section.

Symptoms : Dull aching abdominal pain Dysmenorrhea

Dyschezia

Disorders of menstruation Dyspareunia

Only 20% of women will show up with symptoms

DIAGNOSIS :

*USG abdomen shows , irregular walls with low level echos within and occasional high level echogenic areas which are blood clots.

*CT/MRI has no additional advantage than USG Haematological investigations will be normal

However CA-125 is increased in endometriosis although levels are lower than they are in ovarian carcinoma

*Laparoscopic findings : Powder burns / Gunshot lesion

MANAGEMENT :

This requires both surgical excision and hormonal suppression 1- Progestational drugs 20-100mg p/o for 6months, have been used to treat symptomatic endometriosis.medroxyprogesterone acetate is mostly used.

Levonorgestrel containing IUDs has recently been used for treatment of rectovgainal endometriosis

  1. Oral contraceptive pills ,can be given cyclic or continuous fashion, however monophasic formulation seems more logical than multiphasic pill for continuous therapy.the usual regime is continuous treatment with one pill daily for 6-12 months.
  1. GNRH agonist – causes pseudomenopause and pseudo pregnancy.given for 6months.
  1. Gestrinone – is a 19- nortestosterone derivative steroid having androgenic, antiprogestinic, antiestrogenic actions,thus extensively used in endometriosis.given 2.5mg-10mg On a twice or thrice weekly schedule.
  1. Danazol can also be used. But not used now a days.

It is believed that hormonal suppression is only partially effective.

For endometriosis hormonal suppression may be effective but in scar endometriosis hormonal supplements aren’t useful.surgery is the choice.

Surgical treatment : Excision

Most effective

Surgery for the treatment of endometriosis can be performed via laparotomy or laparoscopy. Laparoscopy offers advantage over laparotomy in better visualisation,less time,less tissue trauma,desiccation,smaller incision and speedy postoperative recovery. Post operative adhesions and complications may also be less in laparoscopy.

Peritoneal implants of endometriosis can be ablated with unipolar or bipolar electro surgical instruments or lasers or excised by sharp dissection.

POST OPERATIVE MANAGEMENT

In order to control the recurrence, progesterone can be given for 4-5 months.

If the scar is relatively large then can be given up to 9months.
