Management of Surgical Complications Indian Medical PG Practice Questions and MCQs
Practice Indian Medical PG questions for Management of Surgical Complications. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Management of Surgical Complications Indian Medical PG Question 1: Which of the following is the most devastating complication of cataract surgery?
- A. Endophthalmitis (Correct Answer)
- B. Optic neuropathy
- C. Retinal detachment
- D. Vitreous loss
Management of Surgical Complications Explanation: ***Endophthalmitis***
- **Endophthalmitis** is a severe intraocular infection following cataract surgery that can rapidly lead to irreversible vision loss or even loss of the eye if not promptly treated.
- It is considered the most devastating complication due to its acute onset and high potential for **permanent vision impairment**.
*Optic neuropathy*
- While optic neuropathy can cause visual loss, it is a less common direct complication of cataract surgery compared to endophthalmitis.
- It typically results from processes like **ischemia** or severe orbital inflammation, which are rare occurrences immediately post-cataract surgery.
*Retinal detachment*
- **Retinal detachment** is a serious complication, but generally occurs at a lower rate than endophthalmitis and often has a better visual prognosis with timely surgical repair.
- It is a known risk, particularly in patients with pre-existing **myopia** or prior posterior capsular rupture, but not necessarily the *most* devastating.
*Vitreous loss*
- **Vitreous loss** is an intraoperative complication that increases the risk of other issues like retinal detachment, cystoid macular edema, and endophthalmitis but is not, in itself, the most devastating.
- Proper surgical technique and management during the procedure can mitigate many of its long-term sequelae.
Management of Surgical Complications Indian Medical PG Question 2: In which of the following conditions does IOL implantation after cataract surgery require the greatest caution and specialized management?
- A. Fuchs' heterochromic iridocyclitis
- B. Psoriatic arthritis
- C. Reiter's syndrome
- D. Juvenile rheumatoid arthritis (Correct Answer)
Management of Surgical Complications Explanation: ***Juvenile rheumatoid arthritis***
- Patients with **juvenile rheumatoid arthritis (JRA)**, particularly those with **pauciarticular JRA** and **ANA positivity**, are at high risk for developing chronic uveitis, which can lead to significant cataract formation and severe postoperative complications.
- Due to the high risk of severe postoperative inflammation, glaucoma, and vision loss, IOL implantation in JRA patients requires extensive preoperative optimization of inflammation and careful intraoperative/postoperative management.
*Fuchs' heterochromic iridocyclitis*
- This condition presents with chronic, low-grade, **non-granulomatous anterior uveitis** and often leads to cataract formation.
- While IOL implantation in these patients is generally well-tolerated, it does not pose the same high risk of severe postoperative inflammation and complications as seen in JRA-associated uveitis.
*Psoriatic arthritis*
- Psoriatic arthritis can be associated with acute anterior uveitis, but it typically presents as an acute, intermittent inflammation.
- The risk of chronic, severe uveitis leading to complex cataract surgery and significant postoperative complications is not as consistently high or as severe as in JRA.
*Reiter's syndrome*
- Reiter's syndrome (now part of **reactive arthritis**) is another seronegative spondyloarthropathy that can cause acute anterior uveitis.
- Similar to psoriatic arthritis, the uveitis is usually acute and self-limiting, and while ocular inflammation needs to be controlled, the risk profile for IOL implantation is not as challenging as in JRA.
Management of Surgical Complications Indian Medical PG Question 3: Which of the following is NOT a known cause of posterior subcapsular cataract?
- A. Diabetes mellitus
- B. Wilson's Disease (Correct Answer)
- C. Myotonic dystrophy
- D. Ionizing radiation
Management of Surgical Complications Explanation: ***Wilson's Disease***
- This is the **CORRECT ANSWER** because Wilson's disease does **NOT** cause posterior subcapsular cataract.
- **Wilson's disease** is characterized by a **Kayser-Fleischer ring** (copper deposition in Descemet's membrane of the cornea) and less commonly by a **sunflower cataract** (copper deposition in the **anterior lens capsule**, not posterior).
- The sunflower cataract has a characteristic appearance with petal-like opacities radiating from the center, but it affects the anterior capsule, not the posterior subcapsular region.
*Myotonic dystrophy*
- **Myotonic dystrophy** is a well-known cause of specific cataracts, including a distinctive **"Christmas tree" cataract**, which often begins as a **posterior subcapsular cataract**.
- This condition is a systemic autosomal dominant disorder affecting multiple systems, including skeletal muscle, cardiac muscle, and the eyes.
*Ionizing radiation*
- Exposure to **ionizing radiation**, such as X-rays or radiation therapy, is a classic and recognized risk factor for developing **posterior subcapsular cataracts**.
- The lens epithelial cells at the posterior pole are highly susceptible to damage from radiation, leading to migration and abnormal differentiation causing opacification.
*Diabetes mellitus*
- **Diabetes mellitus** is a significant risk factor for various types of cataracts, including both **snowflake cataracts** (in acute uncontrolled diabetes) and more commonly, **posterior subcapsular cataracts** in chronic diabetes.
- High blood glucose levels lead to osmotic changes (sorbitol accumulation via the polyol pathway) and oxidative stress within the lens, contributing to cataract formation.
Management of Surgical Complications Indian Medical PG Question 4: Which laser is used for posterior capsular opacification (PCO)?
- A. Krypton
- B. Argon
- C. Nd:YAG (Correct Answer)
- D. Diode laser
Management of Surgical Complications Explanation: ***ND-YAG***
- The **Nd:YAG laser** is specifically used for **posterior capsulotomy**, a procedure to treat **posterior capsular opacification (PCO)**, also known as secondary cataract.
- It creates a small opening in the opacified posterior capsule using **photodisruption**, which vaporizes the tissue.
*Krypton*
- **Krypton lasers** are typically used in **photocoagulation** for retinal conditions, such as **diabetic retinopathy** or **retinal tears**.
- They are not used for incising ocular tissues like the posterior capsule due to their wavelength and photocoagulative nature.
*Argon*
- **Argon lasers** are primarily used in **retinal photocoagulation** for conditions like **diabetic retinopathy**, **retinal vein occlusions**, and also for **trabeculoplasty** in glaucoma.
- Like krypton lasers, their mechanism of action involves thermal coagulation of tissue, not photodisruption of the posterior capsule.
*Diode laser*
- **Diode lasers** have various applications in ophthalmology, including **transscleral cyclophotocoagulation** for glaucoma and **retinal photocoagulation**.
- They are not used for posterior capsulotomy as their wavelength and energy delivery are unsuitable for this specific procedure.
Management of Surgical Complications Indian Medical PG Question 5: All are ophthalmological emergencies except -
- A. Endophthalmitis
- B. CRVO (Correct Answer)
- C. Acute congestive glaucoma
- D. CRAO
Management of Surgical Complications Explanation: ***CRVO***
- Central Retinal Vein Occlusion (CRVO) is characterized by painless **vision loss** due to retinal hemorrhage and edema, but it is generally *not* considered an immediate, vision-threatening emergency in the same vein as the other options.
- While it requires prompt evaluation and management to preserve vision, CRVO allows for a less urgent intervention compared to conditions that can lead to permanent vision loss within hours.
*Endophthalmitis*
- **Endophthalmitis** is a severe inflammation of the intraocular fluids and tissues, typically caused by infection, and can lead to rapid and irreversible vision loss if not treated urgently.
- It presents with pain, redness, reduced vision, and hypopyon (pus in the anterior chamber), necessitating immediate antibiotic treatment and surgical intervention.
*Acute congestive glaucoma*
- **Acute congestive glaucoma** (acute angle-closure glaucoma) involves a sudden increase in intraocular pressure, causing severe pain, redness, corneal edema, and profound vision loss.
- If left untreated, the high pressure can cause irreversible damage to the optic nerve within hours, making it a true ocular emergency.
*CRAO*
- **Central Retinal Artery Occlusion (CRAO)** is a sudden, painless loss of vision in one eye due to blockage of the central retinal artery, leading to retinal ischemia.
- It is an ocular emergency because irreversible retinal damage and vision loss can occur within 90-120 minutes of the occlusion, requiring immediate intervention to restore blood flow.
Management of Surgical Complications Indian Medical PG Question 6: SAFE strategy is recommended for-
- A. Diabetic retinopathy
- B. Trachoma (Correct Answer)
- C. Glaucoma
- D. Cataract
Management of Surgical Complications Explanation: ***Trachoma***
* The **SAFE strategy (Surgery, Antibiotics, Facial Cleanliness, Environmental improvement)** is the WHO-recommended public health approach for the elimination of **trachoma**, a chronic eye infection caused by *Chlamydia trachomatis*.
* This comprehensive strategy addresses both active infection and its blinding sequelae, specifically **trichiasis** (in-turned eyelashes) through surgery.
*Diabetic retinopathy*
* Management of diabetic retinopathy primarily involves **blood sugar control, regular ophthalmologic exams, laser photocoagulation, and anti-VEGF injections**, not the SAFE strategy.
* The focus is on preventing and treating retinal damage caused by **diabetes**, which is distinct from infectious causes.
*Glaucoma*
* Glaucoma is characterized by **optic nerve damage** and visual field loss, usually due to elevated intraocular pressure, and is managed with **medication, laser therapy, or surgery (e.g., trabeculectomy)**.
* It is a **neurodegenerative condition**, not an infectious disease, so the SAFE strategy is not applicable.
*Cataract*
* Cataracts involve the **clouding of the natural lens** of the eye, leading to blurred vision, and are primarily treated through **surgical removal of the cloudy lens** and implantation of an artificial intraocular lens.
* This condition is age-related or can be caused by trauma or disease, but it is **not an infection** for which the SAFE strategy would be relevant.
Management of Surgical Complications Indian Medical PG Question 7: A 25 year old male is receiving conservative management for an appendicular mass since 3 days now presents with a rising pulse rate, tachycardia and fever. The mode of management must be -
- A. Proceed to laparotomy and appendicectomy (Correct Answer)
- B. Intravenous antibiotics
- C. Continue Ochsner Sherren regimen with close monitoring
- D. Continue conservative management
Management of Surgical Complications Explanation: ***Proceed to laparotomy and appendicectomy***
- A **rising pulse rate, tachycardia, and fever** indicate **worsening sepsis** or **perforation** of the appendicular mass, necessitating urgent surgical intervention.
- Continuing conservative management in the face of these signs carries a high risk of **morbidity and mortality** from peritonitis or widespread sepsis.
*Continue Ochsner Sherren regimen with close monitoring*
- The Ochsner Sherren regimen is a **conservative approach** for a stable appendicular mass, which is no longer the case with signs of deterioration.
- **Clinical worsening** (tachycardia, rising fever, increased pulse) signifies failure of conservative management and requires a shift to surgical intervention.
*Continue conservative management*
- Continuing conservative management despite **signs of deterioration** (rising pulse, tachycardia, fever) would lead to further progression of the disease and potential life-threatening complications.
- These symptoms suggest that the infection is **not contained** and is likely spreading, indicating the need for immediate surgical treatment.
*Intravenous antibiotics*
- While intravenous antibiotics are part of the initial conservative management, they are **insufficient** alone for an appendicular mass showing signs of deterioration.
- The worsening clinical picture suggests a **failed antibiotic response** or a more severe underlying issue (e.g., abscess rupture) that requires surgical drainage or removal.
Management of Surgical Complications Indian Medical PG Question 8: A 6-month-old child presents with an umbilical hernia measuring 3 cm in diameter. What is the management protocol?
- A. Immediate surgical repair
- B. Elective surgery at 5 years of age
- C. Hernioplasty for repair
- D. Observation until 2 years of age, then surgery if unresolved (Correct Answer)
Management of Surgical Complications Explanation: ***Observation until 2 years of age, then surgery if unresolved***
- Most **umbilical hernias** in infants and young children **resolve spontaneously** by the age of 2 years, making observation the initial management for uncomplicated cases.
- Surgical intervention is typically considered if the hernia persists beyond **2-4 years of age**, is symptomatic, or demonstrates features of incarceration regardless of age.
*Immediate surgical repair*
- Immediate surgery is reserved for cases with **incarceration** or **strangulation**, which are not indicated by a "symptomatic" hernia in this context.
- Given the high rate of spontaneous closure, most umbilical hernias do not require urgent intervention.
*Elective surgery at 5 years of age*
- Waiting until 5 years of age to consider surgery might delay treatment for some children whose hernias are unlikely to close spontaneously after the age of 2-4 and could lead to prolonged parental anxiety.
- The general consensus is to recommend surgery if the hernia persists beyond **2-4 years**, rather than a fixed age of 5.
*Hernioplasty for repair*
- While hernioplasty is the surgical technique for repair, the question asks about the overall management protocol, which includes initial observation.
- Applying this term as an immediate solution for a 6-month-old's uncomplicated umbilical hernia would bypass the recommended period of **conservative management**.
Management of Surgical Complications Indian Medical PG Question 9: 3rd degree genital prolapse in the first trimester of pregnancy is managed by :
- A. Le Fort's repair
- B. Right transvaginal sacrospinous colpopexy
- C. Fothergill's repair
- D. Ring pessary (Correct Answer)
Management of Surgical Complications Explanation: ***Ring pessary***
- A ring pessary is a **non-surgical** option often used during pregnancy to support the uterus and prevent further prolapse, especially in the first trimester.
- It provides **conservative management**, avoiding surgical risks to both mother and fetus during early pregnancy.
*Le Fort's repair*
- **Le Fort's repair** is a colpocleisis procedure, typically performed on elderly women who are no longer sexually active, as it surgically obliterates the vaginal canal. It is contraindicated in pregnancy and unlikely to be performed in a woman of childbearing age who is pregnant.
*Right transvaginal sacrospinous colpopexy*
- This is a **surgical procedure** to correct vaginal vault prolapse by attaching the vaginal apex to the sacrospinous ligament. It is inappropriate for managing prolapse in the first trimester of pregnancy due to surgical risks and potential fetal harm.
*Fothergill's repair*
- **Fothergill's repair (Manchester repair)** is a surgical procedure that involves cervical amputation, shortening of the cardinal ligaments, and colporrhaphy. This surgery is not suitable during pregnancy due to the risk of miscarriage and is typically reserved for cases of uterocervical elongation causing prolapse in non-pregnant women.
Management of Surgical Complications Indian Medical PG Question 10: Gold standard procedure to reduce recurrence of pterygium after surgical excision is
- A. Thiotepa
- B. Amniotic membrane grafting
- C. Conjunctival autograft (Correct Answer)
- D. Beta-radiation
Management of Surgical Complications Explanation: ***Conjunctival autograft***
- **Conjunctival autografting** involves transplanting a piece of healthy conjunctiva from the superior bulbar conjunctiva to the bare scleral bed after pterygium excision, acting as a barrier to fibrovascular proliferation.
- This technique has consistently shown the **lowest recurrence rates** in comparative studies, making it the **gold standard** for preventing pterygium recurrence due to its high success rate and safety profile.
*Thiotepa*
- **Thiotepa** is an **antimetabolite** that inhibits DNA synthesis and cell proliferation, used topically post-excision to reduce recurrence by suppressing fibroblast activity.
- While it can lower recurrence rates compared to simple excision, its efficacy is generally **less than conjunctival autografting**, and it carries risks of corneal toxicity and limbal stem cell deficiency.
*Amniotic membrane grafting*
- **Amniotic membrane grafting** involves placing processed amniotic membrane over the scleral bed, which has anti-inflammatory, anti-scarring, and pro-epithelialization properties.
- It is an effective option, especially for **large pterygia** or for patients at high risk of recurrence, but its recurrence rates are generally **not as low as those achieved with conjunctival autografting**, and the graft can sometimes detach.
*B- radiation*
- **Beta-radiation** (strontium-90) is a form of adjuvant therapy applied to the scleral bed immediately after pterygium excision to inhibit fibroblast proliferation and reduce recurrence.
- It is effective but associated with potential complications such as **scleral melt**, corneal scarring, and cataract formation, making it a less preferred option than conjunctival autografting, especially in primary cases.
