Match each postoperative clinical presentation following abdominal surgery to the most likely diagnosis.

  • Sudden, copious drainage of serosanguineous fluid from a midline laparotomy incision on postoperative day 7, with intact skin sutures.Fascial dehiscence
  • Nausea, obstipation, and abdominal distention on postoperative day 3, with X-ray revealing uniformly dilated small and large intestine without a transition point.Postoperative ileus
  • Colicky abdominal pain, recurrent vomiting, and hyperactive bowel sounds 3 weeks after surgery, with CT showing a discrete bowel transition point.Adhesive small bowel obstruction
  • Spiking fevers, leukocytosis, and a boggy, tender mass on digital rectal examination on postoperative day 6 following surgery for a perforated viscus.Pelvic abscess

Cevap

Presentation 1 matches Fascial dehiscence; Presentation 2 matches Postoperative ileus; Presentation 3 matches Adhesive small bowel obstruction; Presentation 4 matches Pelvic abscess.
Postoperative complications follow distinct clinical patterns. Fascial dehiscence is heralded by sudden serosanguineous drainage. Ileus is a temporary functional motility loss globally affecting the bowel. Mechanical obstruction features localized blockage with hyperactive upstream motility. Pelvic abscesses present with infectious symptoms and dependent fluid collections.

Adım Adım Çözüm

1
Analyze the timing and nature of the surgical complication for the first presentation.
Serosanguineous drainage on postoperative day 7 indicates fascial breakdown.
Recognizing classic signs like 'salmon-colored fluid' is key for identifying fascial dehiscence before gross evisceration occurs.
2
Evaluate the imaging findings for the second presentation.
Global bowel dilation without a transition point points to a functional, non-mechanical issue.
Differentiating functional ileus from mechanical obstruction relies heavily on the presence or absence of a discrete transition point.
3
Correlate the physical exam and imaging for the third presentation.
Hyperactive bowel sounds and a discrete transition point confirm a mechanical blockage.
Mechanical obstruction forces the bowel to hyperperistalse against a fixed point, causing colicky pain and high-pitched sounds.
4
Identify the source of infection in the fourth presentation.
Postoperative fever with a boggy rectal mass indicates a dependent fluid collection in the pelvis.
Infected intra-abdominal fluid tends to pool in gravity-dependent areas, such as the rectovesical pouch, palpable on rectal exam.
