Match each patient's post-operative clinical presentation following gastric or bariatric surgery with the most likely diagnosis.

  • A 42-year-old female presents with acute, severe periumbilical pain and tachycardia 18 months following a Roux-en-Y gastric bypass. Abdominal CT reveals a swirling appearance of the mesenteric fat and vessels.Internal hernia
  • A 48-year-old male who underwent a Billroth II gastrojejunostomy 4 months ago complains of nausea, palpitations, and diaphoresis occurring 20 minutes after consuming meals high in carbohydrates.Early dumping syndrome
  • A 52-year-old female presents with worsening epigastric pain and melena 1 year after a Roux-en-Y gastric bypass. She frequently uses naproxen for osteoarthritis.Marginal ulceration
  • A 65-year-old male who had a Billroth II reconstruction 3 years ago reports severe postprandial abdominal pain that is suddenly relieved following large-volume, purely bilious emesis.Afferent loop syndrome

Cevap

The correct matches correlate classic post-gastric surgical presentations with their underlying pathophysiology: mesenteric swirl sign indicates an internal hernia, postprandial vasomotor symptoms indicate early dumping syndrome, NSAID-induced bleeding indicates marginal ulceration, and pain relieved by bilious emesis indicates afferent loop syndrome.
Each presentation describes a classic complication of gastric surgery. Internal hernias are mechanical complications of Roux-en-Y bypass causing mesenteric twisting. Early dumping involves rapid gastric emptying of hyperosmolar loads causing autonomic instability. Marginal ulcers are mucosal defects exacerbated by NSAIDs. Afferent loop syndrome is a mechanical outflow obstruction of the bilio-pancreatic limb that decompresses retrogradely.

Adım Adım Çözüm

1
Analyze the time course and imaging for the first patient.
The swirl sign on CT after a Roux-en-Y gastric bypass strongly indicates an internal hernia.
Surgical creation of mesenteric defects allows bowel loops to herniate and twist, creating a surgical emergency.
2
Evaluate the symptom trigger for the second patient.
Vasomotor symptoms 20 minutes after high-carbohydrate meals match early dumping syndrome.
Loss of the pyloric sphincter allows rapid transit of hyperosmolar food boluses, causing fluid shifts into the bowel lumen.
3
Identify the risk factor and presentation for the third patient.
NSAID use and melena after Roux-en-Y point to marginal ulceration.
The jejunal mucosa at the anastomosis is highly susceptible to acid and NSAID-induced mucosal injury.
4
Assess the relief pattern for the fourth patient.
Postprandial pain relieved by large-volume bilious emesis defines afferent loop syndrome.
A partially obstructed afferent limb decompresses suddenly into the stomach, rapidly relieving the pressure and pain.
