Match each patient's clinical presentation with the most appropriate procedural or operative intervention.

  • A 67-year-old man with recurrent diverticulitis now presents with pneumaturia, recurrent urinary tract infections, and a CT scan confirming a colovesical fistula. He is nutritionally replete, hemodynamically stable, and lacks signs of acute sepsis.Elective single-stage colonic resection with primary anastomosis
  • A 72-year-old woman with a history of biliary colic presents with obstipation, bilious vomiting, and abdominal distension. Imaging reveals pneumobilia, dilated small bowel loops, and a calcified structure in the terminal ileum.Exploratory laparotomy with enterolithotomy alone
  • A 28-year-old man is brought in after a motorcycle crash. He is hemodynamically stable with a normal FAST exam. Computed tomography of the abdomen reveals a Grade III splenic laceration without active contrast extravasation or hollow viscus injury.Non-operative management with close hemodynamic observation
  • A 54-year-old man who underwent a laparoscopic appendectomy for perforated appendicitis 7 days ago now exhibits spiking fevers, leukocytosis, and a 5.5-cm localized fluid collection in the rectovesical pouch on CT scan.Image-guided transrectal or percutaneous catheter drainage

Cevap

Match the colovesical fistula patient to elective single-stage resection; the gallstone ileus patient to enterolithotomy alone; the blunt splenic trauma patient to non-operative management; and the post-operative abscess patient to image-guided drainage.
Each matching pair requires recognizing clinical indicators and applying standard surgical guidelines. A colovesical fistula in a stable, well-nourished patient allows for an elective single-stage resection without a stoma. Gallstone ileus requires urgent relief of the mechanical obstruction via enterolithotomy, deferring extensive biliary repair. Hemodynamically stable solid organ injuries without active contrast extravasation are managed non-operatively. Post-operative intra-abdominal abscesses are definitively treated with image-guided drainage, avoiding the morbidity of an open re-exploration.

Adım Adım Çözüm

1
Identify the underlying pathology in each clinical vignette based on history, physical, and imaging findings.
Diagnoses identified: 1) Diverticular colovesical fistula, 2) Gallstone ileus, 3) Grade III splenic laceration without blush, 4) Post-operative pelvic abscess.
Accurate diagnosis is the prerequisite for determining the correct surgical pathway.
2
Assess patient stability and the acuteness of the condition to determine if intervention should be emergent, elective, or non-operative.
Patient 1 is stable for elective surgery. Patient 2 needs emergent relief of obstruction. Patient 3 is hemodynamically stable, permitting observation. Patient 4 requires minimally invasive intervention for sepsis control.
Surgical dogma dictates that patient hemodynamics and local tissue conditions (inflammation) dictate the extent and timing of interventions.
3
Pair the diagnosed conditions with standard-of-care surgical interventions.
Fistula -> Single-stage resection. Gallstone ileus -> Enterolithotomy. Spleen -> Observation. Abscess -> Percutaneous drainage.
This aligns the clinical presentations directly with established surgical management guidelines.

Operative decision-making in abdominal surgery depends heavily on patient hemodynamic stability, the presence of localized vs. generalized sepsis, and minimizing surgical morbidity in highly inflammatory states.
