Match each postoperative clinical presentation with the most appropriate definitive management or next step in diagnosis.

  • A 62-year-old man on postoperative day 4 following a small bowel resection presents with diffuse abdominal distension, absent bowel sounds, and nausea. Laboratory studies reveal a serum potassium of 2.7 mEq/L.Intravenous potassium repletion and continued bowel rest
  • A 45-year-old woman on postoperative day 4 following a laparoscopic cholecystectomy develops right upper quadrant pain. A hepatobiliary iminodiacetic acid (HIDA) scan confirms active bile extravasation from the cystic duct stump.Endoscopic retrograde cholangiopancreatography (ERCP) with biliary stenting
  • A 38-year-old man on postoperative day 1 following damage-control laparotomy with fascial closure develops oliguria, hypoxia, and elevated ventilator peak airway pressures. Intravesical pressure is measured at 28 mmHg.Immediate decompressive laparotomy
  • A 50-year-old woman on postoperative day 3 following a Roux-en-Y gastric bypass develops sudden severe abdominal pain, a heart rate of 135/min, and an upper gastrointestinal contrast study showing extravasation at the gastrojejunostomy.Urgent surgical re-exploration
  • A 25-year-old man on postoperative day 7 following an appendectomy for perforated appendicitis develops spiking fevers. A CT scan of the pelvis shows a 6-cm rim-enhancing fluid collection in the rectovesical pouch.Percutaneous or transrectal abscess drainage

Cevap

Each postoperative complication requires a specific targeted intervention: Ileus requires potassium repletion; cystic duct leaks require ERCP; abdominal compartment syndrome requires decompressive laparotomy; anastomotic leaks require urgent surgical re-exploration; and postoperative abscesses require percutaneous drainage.
Optimal management of postoperative complications depends entirely on the specific pathophysiology. Mechanical issues like anastomotic leaks and compartment syndrome require immediate surgical intervention, whereas functional issues (ileus) or localized collections/fistulas (abscess, cystic duct leak) are appropriately managed with medical optimization or less invasive interventional procedures.

Adım Adım Çözüm

1
Identify the complication in the 62-year-old man.
Paralytic ileus exacerbated by hypokalemia.
Bowel rest and electrolyte correction are the mainstays of treatment for functional ileus.
2
Identify the complication in the 45-year-old woman.
Cystic duct stump leak.
ERCP with stenting lowers biliary tract pressure, creating a path of least resistance that allows the cystic duct stump to close.
3
Identify the complication in the 38-year-old man.
Abdominal compartment syndrome.
Intravesical pressure >20 mmHg with end-organ dysfunction (oliguria, high peak airway pressures) dictates immediate fascial opening.
4
Identify the complication in the 50-year-old woman.
Anastomotic leak after gastric bypass.
Contrast extravasation with hemodynamic instability (tachycardia) is a surgical emergency necessitating immediate re-exploration.
5
Identify the complication in the 25-year-old man.
Postoperative pelvic abscess.
Fluid collections larger than 3-4 cm following abdominal infection require source control via percutaneous or transrectal drainage.
