Q: Which of the following statements about hysterosalpingography, as a diagnostic procedure, are correct? I. Tubal patency assessment following tuboplasty operation II. Diagnosis of uterine synechiae III. Detection of IUD IV. Diagnosis of subserosal fibroid Select the answer using the code given below :

I, II and III. ***I, II and III*** Hysterosalpingography (HSG) is a radiological procedure that uses contrast material injected into the uterus to visualize the **uterine cavity** and **fallopian tubes** under fluoroscopy. It is specifically useful for: **Statement I - Tubal patency assessment following tuboplasty operation** ✓ - HSG is the standard procedure to evaluate whether fallopian tubes remain patent after reconstructive tubal surgery **Statement II - Diagnosis of uterine synechiae** ✓ - HSG excellently demonstrates intrauterine adhesions (Asherman's syndrome) as filling defects in the uterine cavity **Statement III - Detection of IUD** ✓ - Radiopaque IUDs are easily visualized on HSG, and the procedure can confirm proper IUD position within the uterine cavity **Statement IV - Diagnosis of subserosal fibroid** ✗ - **Subserosal fibroids** project outward from the uterine serosa into the peritoneal cavity - HSG only outlines the **endometrial cavity** and **tubal lumen**, not external uterine surfaces - These fibroids do not impinge on the uterine cavity and therefore cannot be visualized by HSG - Better diagnosed by **ultrasound** or **MRI** *I, II and IV* - While HSG is excellent for assessing tubal patency and diagnosing uterine synechiae (I and II), it cannot diagnose **subserosal fibroids** which are located on the outer surface of the uterus and do not affect the uterine cavity outline. *II, III and IV* - This option correctly identifies HSG's utility in diagnosing **uterine synechiae** and detecting **IUDs**, but incorrectly includes **subserosal fibroids** which cannot be visualized by this procedure. *I, III and IV* - This option accurately includes HSG's role in assessing **tubal patency** and detecting **IUDs**, but mistakenly includes diagnosis of **subserosal fibroids** which require imaging modalities that visualize the external uterine surface.

Q: Which of the following are indications of endometrial sampling? I. Routine screening in asymptomatic premenopausal women II. Endometrial polyp III. Postmenopausal bleeding IV. Abnormal uterine bleeding Select the correct answer using the code given below :

II, III and IV. ***II, III and IV*** - **Endometrial polyps** require sampling for histopathological diagnosis and to assess for malignancy, especially when symptomatic or found in postmenopausal women. - **Postmenopausal bleeding** is a red-flag symptom that mandates endometrial sampling to rule out **endometrial hyperplasia** or **endometrial carcinoma**, as 5-10% of cases are associated with malignancy. - **Abnormal uterine bleeding** in premenopausal or perimenopausal women often requires endometrial sampling to investigate underlying causes such as **endometrial hyperplasia**, **polyps**, **endometritis**, or **malignancy**. *I, II and IV* - This option incorrectly includes **routine screening in asymptomatic premenopausal women (I)**, which is NOT an indication for endometrial sampling. - Endometrial sampling is not recommended for routine screening in asymptomatic women without risk factors or concerning symptoms. *I, III and IV* - This option also incorrectly includes **routine screening (I)** as an indication. - Additionally, it excludes **endometrial polyps (II)**, which are a definite indication for endometrial sampling when detected. *I, II and III* - This option incorrectly includes **routine screening (I)** while excluding **abnormal uterine bleeding (IV)**. - **Abnormal uterine bleeding** is one of the most common and important indications for endometrial evaluation across all age groups.

Q: A 30-year-old P3L3 female presents in Gynaecology emergency with acute abdominal pain and vaginal bleeding of short duration (1 hour). She gives history of tubal ligation after birth of third child. On examination, right adnexal tenderness was found and os was closed. What is the probable diagnosis?

Ectopic pregnancy. ***Ectopic pregnancy*** - This patient presents with **acute abdominal pain** and **vaginal bleeding** of short duration, with right adnexal tenderness and a closed os, highly suggestive of an ectopic pregnancy even after a tubal ligation. Tubal ligation does not provide 100% protection against pregnancy. - The history of **tubal ligation** increases the risk for ectopic pregnancy, as fertilization can still occur with the ovum implanting outside the uterus. *Complete abortion* - A complete abortion would typically involve the **passage of all products of conception**, after which the pain and bleeding would subside, and the os would generally be closed or closing. - This patient's symptoms are more acute and localized to the **adnexa**, which is less typical for a complete abortion occurring in a non-pregnant uterus (given the tubal ligation). *Pelvic inflammatory disease* - **Pelvic inflammatory disease (PID)** usually presents with **vaginal discharge/cervicitis**, **fever**, and bilateral abdominal pain. - While adnexal tenderness can be present, the acute onset with vaginal bleeding in a patient post-tubal ligation makes ectopic pregnancy a more concerning and probable diagnosis. *Appendicitis* - **Appendicitis** typically presents with **right lower quadrant pain** that often migrates from the periumbilical region, but usually lacks vaginal bleeding or adnexal tenderness. - The combination of **vaginal bleeding** and adnexal tenderness points away from appendicitis and more towards a gynecological origin.

Q: Which of the following is measured without any straining while examination under POP-Q system?

TVL. ***TVL*** - **Total Vaginal Length (TVL)** is the **only measurement** in the POP-Q system that is taken **exclusively at rest without straining**. - It is measured from the **hymen to the posterior fornix** (or vaginal cuff in post-hysterectomy cases) with the patient in supine lithotomy position. - This measurement reflects the overall depth of the vagina and provides important anatomical context for prolapse assessment. *Point D* - **Point D** represents the location of the **posterior fornix** (or vaginal cuff scar in post-hysterectomy). - In the POP-Q system, Point D is measured **both at rest and with maximal straining** to assess the degree of **uterine descent or vaginal vault prolapse**. - The difference between rest and strain measurements helps quantify the extent of apical support defects. *GH* - **Genital Hiatus (GH)** is measured from the **external urethral meatus to the posterior hymen**. - GH is measured **both at rest and during maximal Valsalva straining** in the standard POP-Q protocol. - The measurement increases with straining as pelvic floor muscles relax, reflecting the functional capacity of the pelvic floor. *Pb* - **Perineal Body (Pb)** is measured from the **posterior margin of the genital hiatus to the mid-anal opening**. - Like GH, Pb is measured **both at rest and with straining** in the POP-Q examination. - Changes with straining can indicate perineal descent or posterior compartment defects like rectocele.
