Postoperative Care and Complication Management
What this domain tests
Recognition and first action for complications in the first 30 days, plus the later problems - stricture, marginal ulcer, internal hernia - that bring patients back to the clinic.
Time-linked differential
- Days 1–7: anastomotic or staple-line leak, bleeding, pulmonary embolism, dehydration.
- Weeks 2–8: stricture with progressive dysphagia to solids, wound infection, early marginal ulcer.
- Months 1–12: marginal ulcer, internal hernia, gallstones, nutritional deficiency.
Red flags
- Tachycardia is the earliest and most reliable leak sign; unexplained HR above 120 warrants imaging and surgeon contact.
- Fever, abdominal pain, left shoulder pain, oliguria, or rising CRP support leak.
- Persistent vomiting after RYGB suggests obstruction, stricture, or internal hernia - get CT with contrast rather than reassurance.
- Dysphagia at 6 weeks suggests stricture; dysphagia on day 1 is usually edema.
Worked example
Postoperative day 3 after RYGB: HR 126, temperature 38.2°C, left shoulder pain, abdomen non-peritonitic. Reasoning: shoulder pain reflects diaphragmatic irritation from subphrenic contamination, and a benign abdominal exam does not exclude leak. Obtain CT with oral contrast and call the surgeon. Do not attribute the tachycardia to pain or ambulation alone.
Traps
- Anchoring on "pain" as the cause of tachycardia and delaying imaging.
- Treating marginal ulcer with a proton pump inhibitor while the patient continues NSAIDs or smoking.
- Sending a RYGB patient with recurrent vomiting home on antiemetics instead of evaluating for internal hernia.
