The operation of choice for infantile hypertrophic pyloric stenosis is:
सही उत्तर: ग) Ramstedt's pyloromyotomy
Ramstedt's pyloromyotomy splits the hypertrophied pyloric muscle down to the mucosa. Heller's myotomy is done for achalasia cardia.

-
The characteristic metabolic abnormality in infantile hypertrophic pyloric stenosis is:
सही उत्तर: ख) Hypochloraemic hypokalaemic metabolic alkalosis
Persistent non-bilious vomiting loses gastric HCl, which causes hypochloraemic, hypokalaemic metabolic alkalosis, sometimes with paradoxical aciduria. This must be corrected before Ramstedt's pyloromyotomy.

The definitive diagnosis of Hirschsprung's disease is made by:
सही उत्तर: क) Rectal biopsy showing absence of ganglion cells
Rectal (suction) biopsy showing no ganglion cells, with hypertrophied nerve trunks, is the gold standard. A barium enema can show a transition zone, but it does not confirm the diagnosis.

-
The most common type of intussusception in children is:
सही उत्तर: घ) Ileocolic
Ileocolic intussusception is the most common type. It often starts at hypertrophied Peyer's patches and causes 'red currant jelly' stools. A non-operative air or hydrostatic enema is used first if there is no peritonitis.

In a haemodynamically stable patient with sigmoid volvulus and no signs of peritonitis, the initial treatment of choice is:
सही उत्तर: ग) Endoscopic (sigmoidoscopic) decompression with a flatus tube
Endoscopic decompression relieves most uncomplicated sigmoid volvulus. Elective sigmoid resection is usually planned afterwards because the volvulus often comes back. Emergency resection is for gangrene or peritonitis.

-
The most common site of volvulus of the gut in adults is the:
सही उत्तर: ख) Sigmoid colon
Sigmoid volvulus is the most common type in adults. On X-ray it gives a 'coffee bean' or 'bent inner tube' sign. Caecal volvulus is the next most common.

-
The investigation of choice for a suspected bleeding Meckel's diverticulum in a child is:
सही उत्तर: क) Technetium-99m pertechnetate scan
Tc-99m pertechnetate is taken up by ectopic gastric mucosa, so a Meckel's scan shows the diverticulum. A HIDA scan looks at the biliary system, not gastric mucosa.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
The most common heterotopic (ectopic) tissue found in a Meckel's diverticulum is:
सही उत्तर: घ) Gastric mucosa
Gastric mucosa is the most common ectopic tissue in a Meckel's diverticulum. Its acid causes ulceration and bleeding in the nearby ileum. Pancreatic tissue is the second most common.

-
A hernia whose sac contains a Meckel's diverticulum is called:
सही उत्तर: ग) Littre's hernia
A Littre's hernia contains a Meckel's diverticulum. A Maydl's hernia (hernia-en-W) contains two loops of bowel, and the loop lying inside the abdomen may strangulate.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
A Richter's hernia is one in which:
सही उत्तर: ख) Only part of the circumference of the bowel wall is trapped
In a Richter's hernia only part of the bowel wall is trapped, so it can strangulate without causing complete obstruction. A hernia containing a Meckel's diverticulum is a Littre's hernia.
