Match each clinical presentation in a patient who previously underwent bariatric surgery with the most likely diagnosis.

  • A 42-year-old woman presents with resting tachycardia (125/min), fever, and left shoulder pain on postoperative day 3 following a Roux-en-Y gastric bypass.Anastomotic leak
  • A 35-year-old man presents with intermittent, severe, crampy periumbilical pain and vomiting 18 months after a Roux-en-Y gastric bypass. CT of the abdomen reveals a 'swirl sign' of the mesenteric vessels.Internal hernia
  • A 40-year-old woman presents with colicky right upper quadrant pain, jaundice, and fever one year after a sleeve gastrectomy that resulted in a 40 kg (88 lb) weight loss.Choledocholithiasis
  • A 48-year-old man who recently resumed smoking presents with severe epigastric pain and hematemesis 8 months after a Roux-en-Y gastric bypass.Marginal ulcer
  • A 30-year-old woman presents with palpitations, diaphoresis, and crampy abdominal pain occurring 20 minutes after eating a high-carbohydrate meal, 6 months after a Roux-en-Y gastric bypass.Early dumping syndrome

Cevap

The correct pairings are: the day 3 patient with tachycardia and shoulder pain has an Anastomotic leak; the 18-month postoperative patient with a CT 'swirl sign' has an Internal hernia; the patient with rapid weight loss, jaundice, and fever has Choledocholithiasis; the smoking patient with hematemesis has a Marginal ulcer; and the patient with postprandial vasomotor symptoms has Early dumping syndrome.
Each clinical scenario maps uniquely to a specific post-bariatric complication based on the timeline, vital signs, radiographic findings, and patient risk factors.

Adım Adım Çözüm

1
Analyze the onset timeframe of the complication for each patient.
Patient 1 is in the early postoperative phase (day 3), while the others present months to years after surgery.
Timing distinguishes early technical complications (like leaks) from late anatomical or metabolic complications.
2
Evaluate Patient 1's symptoms of resting tachycardia, fever, and referred shoulder pain.
Matches Anastomotic leak.
Tachycardia > 120/min is the most sensitive indicator of a leak; shoulder pain indicates peritonitis irritating the diaphragm.
3
Evaluate Patient 2's CT imaging finding ('swirl sign') and crampy pain.
Matches Internal hernia.
The Roux-en-Y anatomy creates mesenteric defects. Bowel herniation leads to volvulus, causing the classic 'swirl sign' of mesenteric vessels on CT.
4
Identify the risk factor in Patient 3 (rapid weight loss) alongside Charcot triad.
Matches Choledocholithiasis.
Rapid fat mobilization increases biliary cholesterol saturation, leading to gallstones and subsequent common bile duct obstruction/infection.
5
Assess Patient 4's risk factor (smoking) and symptom of upper gastrointestinal bleeding.
Matches Marginal ulcer.
Smoking causes mucosal ischemia at the gastrojejunal anastomosis, leading to ulceration, pain, and bleeding.
6
Connect Patient 5's diet-triggered autonomic symptoms with altered GI transit.
Matches Early dumping syndrome.
Bypassing the pylorus allows rapid transit of hyperosmolar food boluses, causing fluid shifts and sympathetic activation.

Anahtar Kavram

Post-bariatric surgery complications have distinct timelines (early vs. late) and specific clinical signatures (e.g., tachycardia for leak, swirl sign for internal hernia, diet-triggered autonomic symptoms for dumping syndrome) that dictate definitive management.
