Pediatric Surgery Basics Indian Medical PG Practice Questions and MCQs
Practice Indian Medical PG questions for Pediatric Surgery Basics. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Pediatric Surgery Basics Indian Medical PG Question 1: 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)
Pediatric Surgery Basics 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**.
Pediatric Surgery Basics Indian Medical PG Question 2: A 1-week-old previously healthy infant presents to the emergency room with the acute onset of bilious vomiting. The abdominal plain film in the emergency department (A) and the barium enema done after admission (B) are shown. Which of the following is the most likely diagnosis for this patient?
- A. Hypertrophic pyloric stenosis
- B. Acute appendicitis
- C. Jejunal atresia
- D. Malrotation with volvulus (Correct Answer)
Pediatric Surgery Basics Explanation: ***Malrotation with volvulus***
- The acute onset of **bilious vomiting** in a 1-week-old infant is a **surgical emergency** and highly suggestive of intestinal obstruction, with malrotation with volvulus being a critical consideration.
- The barium enema image (B) shows the **ligament of Treitz** located to the right of the midline, indicating **intestinal malrotation** and a **corkscrew pattern** of the duodenum, which is pathognomonic for **midgut volvulus**.
*Hypertrophic pyloric stenosis*
- Typically presents with **non-bilious projectile vomiting** and palpable **pyloric olive mass**, usually appearing between 3 to 6 weeks of age, not at 1 week with bilious vomiting.
- Imaging would reveal an **elongated, narrowed pyloric channel** (string sign) and thickened pyloric muscle, not the findings seen in the barium study.
*Acute appendicitis*
- This is an **extremely rare diagnosis** in a 1-week-old infant and typically presents with localized pain, fever, and leukocytosis, which are not the primary symptoms described.
- Acute appendicitis would not explain the **bilious vomiting** or the specific findings on the barium study related to intestinal rotation.
*Jejunal atresia*
- Presents with bilious vomiting and abdominal distension, often diagnosed prenatally or shortly after birth due to proximal dilation and distal collapse of the bowel.
- While it causes obstruction, the barium study in jejunal atresia would show a **blind-ending jejunum** and not the distinct malrotation and volvulus features (e.g., corkscrew sign, abnormal Treitz location).
Pediatric Surgery Basics Indian Medical PG Question 3: Which one of the following regarding abdominal pediatric surgery is correct?
- A. Transverse abdominal incision is always used
- B. Bowel must be always anastomosed in double layer
- C. Skin over abdomen can never be closed with subcuticular sutures
- D. Incision can be closed with absorbable suture (Correct Answer)
Pediatric Surgery Basics Explanation: ***Incision can be closed with absorbable suture***
- **Absorbable sutures** are commonly used in pediatric abdominal surgery for closing deeper layers and sometimes skin, as they degrade over time and do not require removal.
- This is particularly beneficial in children to avoid the trauma and discomfort of suture removal and to promote good cosmetic outcomes.
*Transverse abdominal incision is always used*
- While **transverse incisions** are often preferred in pediatric abdominal surgery for their good cosmetic results and lower incidence of incisional hernias, they are not *always* used.
- Other incisions, such as **vertical midline incisions**, may be utilized depending on the surgical exposure required, the specific pathology, or the surgeon's preference.
*Bowel must be always anastomosed in double layer*
- **Bowel anastomoses** in pediatric surgery can be performed using either a **single-layer** or **double-layer** technique.
- The choice depends on surgeon preference, the specific bowel segment involved, and the patient's condition, with both methods demonstrating comparable outcomes in many situations.
*Skin over abdomen can never be closed with subcuticular sutures*
- **Subcuticular sutures** are frequently used for skin closure in pediatric abdominal surgery, especially for their excellent cosmetic results and to avoid external suture removal.
- This technique places the suture material under the skin surface, minimizing scarring and being well-suited for a child's healing skin.
Pediatric Surgery Basics Indian Medical PG Question 4: Which of the following surgeries is contraindicated below 12 years of age?
- A. SMR (Correct Answer)
- B. Rhinoplasty
- C. Septoplasty
- D. Antral puncture
Pediatric Surgery Basics Explanation: ***SMR (Submucous Resection of the septum)***
- SMR procedure involves removing a significant portion of the **septal cartilage and bone**, which is crucial for nasal growth.
- Performing SMR before 12 years of age can lead to severe **facial growth disturbances**, such as a saddle nose deformity, due to interference with the septal growth plate.
*Rhinoplasty*
- While rhinoplasty is generally delayed until nasal growth is complete (around 15-16 years old for girls, 16-17 for boys), it is not absolutely contraindicated structurally before 12 in the same way SMR is.
- The concern is primarily about final aesthetic outcome and patient maturity, not direct damage to major growth centers.
*Septoplasty*
- **Septoplasty** can be performed in younger children for severe nasal obstruction, especially if it significantly impacts breathing or sleep.
- It involves reshaping or repositioning the **septal cartilage and bone** with minimal removal, preserving growth potential.
*Antral puncture*
- **Antral puncture** (or antral lavage) is a procedure to drain the maxillary sinus and can be performed at any age when indicated for sinusitis.
- It does not interfere with facial growth as it targets the sinus cavity walls and does not involve the nasal septum.
Pediatric Surgery Basics Indian Medical PG Question 5: What is the most appropriate method for administering asthma treatment to an infant under one year of age?
- A. MDI with Mask (no spacer)
- B. Nebulizer therapy
- C. MDI with Spacer (no mask)
- D. MDI with Spacer and Mask (Correct Answer)
Pediatric Surgery Basics Explanation: ***MDI with Spacer and Mask***
- For infants and young children, a **metered-dose inhaler (MDI)** used with a **spacer** and a **well-fitting mask** is the **most appropriate** method for delivering asthma medication.
- The spacer helps to reduce the velocity of the aerosol and allows the infant to inhale the medication over several breaths, while the mask ensures the medication is delivered to the airways without significant loss.
- This method is **portable**, **convenient**, and **cost-effective** for routine outpatient management.
*MDI with Spacer (no mask)*
- While a spacer is crucial for optimizing drug delivery from an MDI, an infant cannot effectively seal their lips around a spacer mouthpiece for proper inhalation.
- This method would result in significant **medication loss** and insufficient dose delivery to the lungs.
*MDI with Mask (no spacer)*
- An MDI used directly with a mask without a spacer leads to inefficient drug delivery due to the **high velocity** of the aerosol spray.
- The medication impinges on the back of the throat and face, reducing the amount that reaches the small airways.
*Nebulizer therapy*
- Nebulizers are also an **acceptable and effective option** for infants, particularly in acute settings or when families find them easier to use.
- However, they are **time-consuming** (typically 10-15 minutes per treatment), require a power source or batteries, and are less portable than MDI systems.
- For **routine outpatient management**, an MDI with spacer and mask is generally **preferred** due to its convenience, portability, and comparable efficacy when used correctly.
