Review the clinical scenarios described below. Match each clinical presentation of a gastrointestinal or abdominal pathology with its most appropriate primary surgical or procedural intervention.
- A 35-year-old man with a 10-year history of medically refractory ulcerative colitis who is found to have high-grade dysplasia on a recent surveillance colonoscopy.Total proctocolectomy with ileal pouch-anal anastomosis
- A 62-year-old woman diagnosed with a 4-cm biopsy-proven adenocarcinoma located in the cecum, with a staging CT scan showing no evidence of distant metastasis.Right hemicolectomy with primary ileocolic anastomosis
- A 28-year-old man presenting with severe, continuous, throbbing perianal pain, fever, and a tender, fluctuant, erythematous mass located just outside the anal verge.Immediate surgical or bedside incision and drainage
- A 24-year-old pregnant woman at 18 weeks gestation presenting with right lower quadrant pain, leukocytosis, and an ultrasound demonstrating a non-compressible, 9-mm, blind-ending tubular structure in the right iliac fossa.Prompt laparoscopic appendectomy
Answer
1 matches with Total proctocolectomy; 2 matches with Right hemicolectomy; 3 matches with Immediate incision and drainage; 4 matches with Prompt laparoscopic appendectomy.
The correct pairings align with standard surgical guidelines: comprehensive mucosal resection for pan-colonic premalignant disease, targeted oncologic resection with lymphadenectomy for localized colon cancer, source control via drainage for localized abscesses, and urgent organ removal for acute appendicitis.
