Difficulty: HardGastrointestinal and Abdominal Surgery

Match each clinical presentation with the most appropriate next step in management or definitive surgical intervention.

  • A 55-year-old woman presents with fever, jaundice, and right upper quadrant pain. Her blood pressure is 80/50 mmHg and she is lethargic. Ultrasound reveals a dilated common bile duct.Urgent biliary decompression via endoscopic retrograde cholangiopancreatography
  • A 65-year-old man has a 3-cm biopsy-proven adenocarcinoma located directly at the dentate line. Endoscopic ultrasound confirms invasion through the muscularis propria.Neoadjuvant chemoradiation therapy followed by abdominoperineal resection
  • A 40-year-old man presents with sudden, severe epigastric pain. Upright chest radiograph shows free subdiaphragmatic air. He is tachycardic but normotensive.Exploratory laparotomy with omental (Graham) patch repair
  • A 72-year-old man presents with left lower quadrant pain, fever, and leukocytosis. Computed tomography of the abdomen shows acute diverticulitis with a 5-cm rim-enhancing fluid collection in the pelvis.CT-guided percutaneous drainage
  • A 32-year-old woman with a 15-year history of ulcerative colitis is found to have multifocal high-grade dysplasia on a routine screening colonoscopy.Total proctocolectomy with ileal pouch-anal anastomosis

Answer

Match the presentations to their respective definitive surgical or procedural interventions based on standardized management algorithms.
Each clinical scenario maps strictly to evidence-based surgical guidelines for the management of gastrointestinal emergencies and oncologic indications.

Step-by-Step Solution

1
Identify the underlying pathology for the first patient (hypotension, altered mental status, fever, jaundice, RUQ pain).
The diagnosis is acute suppurative cholangitis (Reynold's pentad).
This is a life-threatening biliary infection that requires immediate intervention.
2
Select the management for acute suppurative cholangitis.
Urgent biliary decompression via ERCP.
ERCP allows for prompt drainage of infected bile and stone extraction, stabilizing the patient.
3
Assess the rectal cancer scenario (3-cm tumor at dentate line, invasion through muscularis propria).
Requires neoadjuvant chemoradiation therapy followed by abdominoperineal resection.
T3 lesions benefit from neoadjuvant therapy, and involvement of the dentate line precludes a sphincter-sparing procedure.
4
Analyze the case of sudden epigastric pain with pneumoperitoneum.
Requires exploratory laparotomy with omental (Graham) patch repair.
Free subdiaphragmatic air signifies a perforated viscus, classically a perforated duodenal ulcer, needing immediate operative closure.
5
Evaluate the management for acute diverticulitis with a 5-cm abscess.
Requires CT-guided percutaneous drainage.
Abscesses >3 cm are amenable to percutaneous drainage, which controls the infection and potentially avoids a multi-stage operation with a colostomy.
6
Determine the treatment for ulcerative colitis complicated by high-grade dysplasia.
Requires total proctocolectomy with ileal pouch-anal anastomosis.
Dysplasia in the setting of inflammatory bowel disease is often multifocal and carries a very high risk of progression to cancer, requiring complete removal of the at-risk mucosa.
