A physician is directing the care of a newly admitted patient who has a history of prior gynecologic surgery and now presents with obstipation, bilious vomiting, and severe, paroxysmal abdominal cramping. Physical examination reveals marked abdominal distension with high-pitched bowel sounds, but no rebound tenderness or rigidity. The physician asks the surgical team to outline the standard algorithmic pathway for this condition, assuming the patient does not exhibit immediate signs of clinical deterioration but eventually fails to resolve the obstruction with nonoperative measures.
Arrange the following interventions in the correct sequential order from initial presentation to final surgical resolution.
- 1Initiation of isotonic crystalloid infusion and placement of a gastric drainage catheter
- 2Acquisition of cross-sectional radiologic imaging to evaluate for impending bowel compromise
- 3Enteral delivery of a water-soluble contrast agent to promote bowel function and predict resolution
- 4Surgical exploration for definitive mechanical relief of the obstruction
Cevap
The correct sequence is: Initial fluid resuscitation and gastric decompression, followed by cross-sectional imaging, then an enteral water-soluble contrast trial, and finally surgical exploration if conservative measures fail.
The algorithmic management of a patient with an uncomplicated mechanical bowel obstruction begins with resuscitation (intravenous fluids and gastric decompression). Once stable, cross-sectional imaging is obtained to rule out complications requiring emergent surgery (e.g., ischemia, closed-loop obstruction). If imaging is reassuring, nonoperative management is pursued. If symptoms fail to improve, an enteral water-soluble contrast agent is administered to both predict resolution and potentially stimulate bowel activity. If this trial fails to resolve the obstruction (e.g., contrast does not reach the colon within 24 hours), the final mandatory step is surgical exploration.

Anahtar Kavram
The standard management algorithm for uncomplicated mechanical bowel obstruction involves sequential escalation from medical resuscitation to definitive imaging, followed by therapeutic contrast challenges, and ultimately surgery for refractory cases.
