What is the best course of action for managing a large complex fluid collection in the left lower quadrant, consistent with a persistent or organizing postoperative hematoma, in a 64-year-old female with a history of gastrojejunal ulcer, bariatric surgery status, and chronic medical renal disease, status post laparoscopic revision of gastrojejunostomy and hiatal hernia repair?

Management of Post-Operative Rectus Sheath Hematoma After Bariatric Surgery Revision

Direct Answer

Continue conservative management with close clinical monitoring, as the ultrasound findings are expected and consistent with the known rectus sheath hematoma that is being appropriately managed non-operatively. 1

Clinical Context and Expected Findings

Your patient's ultrasound findings are entirely consistent with her documented clinical course:

• The 10.6 × 6.6 × 5.3 cm left lower quadrant collection represents the known left rectus sheath hematoma that was identified on CTA after her postoperative hypotension and fall 1
• This hematoma was appropriately managed conservatively with abdominal binder and supportive care during her hospitalization 1
• Stable hemoglobin and improving clinical symptoms (decreasing pain, improving bruising) indicate successful conservative management 1

Recommended Management Algorithm

Immediate Orders (Next 24-48 Hours)

1. Serial Complete Blood Counts

• Order CBC now and repeat in 24 hours to confirm continued hemodynamic stability 1
• Stable or rising hemoglobin confirms that conservative management should continue 1
• Declining hemoglobin (>2 g/dL drop) would necessitate urgent surgical consultation 1

2. Clinical Monitoring Protocol

• Serial abdominal examinations every 6-8 hours focusing on: 1
  • Expansion of ecchymosis beyond current boundaries
  • Increasing abdominal distension
  • New-onset peritoneal signs
  • Hemodynamic instability (tachycardia, hypotension)

3. Continue Abdominal Binder Support

• Maintain external compression to prevent hematoma expansion 1

Indications for Urgent Intervention

You must escalate to surgical exploration immediately if: 1

• Hemodynamic instability develops (HR >110, SBP <90 mmHg despite resuscitation)
• Hemoglobin drops >2 g/dL over 24 hours
• Expanding abdominal girth with signs of ongoing bleeding
• Development of peritoneal signs suggesting bowel injury or anastomotic leak

Angiography with embolization should be considered if: 1

• Hemodynamically stable but with evidence of ongoing bleeding (slowly declining hemoglobin)
• Interventional radiology expertise is available at your facility

What NOT to Order

Do not order repeat imaging at this time because:

• The ultrasound has already characterized the collection as a hematoma 1
• Serial clinical examination and hemoglobin monitoring are superior to repeat imaging for detecting complications 1
• Repeat imaging is only indicated if clinical deterioration occurs 1

Do not perform diagnostic aspiration because:

• Risk of introducing infection into a sterile hematoma 1
• Will not change management in a stable patient 1

Critical Distinction: Hematoma vs. Anastomotic Leak

Your patient does NOT have signs of anastomotic leak: 2, 3

• No free intraperitoneal fluid on ultrasound
• Tolerating oral liquids without difficulty
• No fever or leukocytosis (not mentioned in your presentation)
• Improving clinical course rather than deteriorating

If anastomotic leak were present, you would see: 2, 3

• Free intraperitoneal fluid
• Peritoneal signs
• Inability to tolerate oral intake
• Fever, tachycardia, and clinical deterioration
• This would mandate immediate surgical re-exploration without delay 2, 3

Expected Timeline for Hematoma Resolution

• Hematomas of this size typically organize and resorb over 4-8 weeks 1
• Clinical improvement (decreasing pain, resolving ecchymosis) precedes radiographic resolution 1
• Your patient's improving symptoms indicate appropriate healing trajectory 1

Monitoring for Marginal Ulcer Complications

Given her history of gastrojejunal ulcer requiring revision:

Ensure she is on high-dose PPI therapy for minimum 3-6 months 1, 4

• This is mandatory post-revision to prevent recurrent ulceration 1, 4
• She underwent truncal vagotomy during revision, which reduces but does not eliminate ulcer risk 1, 5

Schedule outpatient endoscopy at 3 months post-revision 1, 4

• Monitor anastomotic healing
• Rule out stenosis or recurrent ulceration
• Obtain biopsies to exclude malignancy (mandatory in all post-bariatric ulcers) 1, 4, 3

Common Pitfalls to Avoid

Do not mistake stable hematoma for surgical emergency 1

• The key differentiator is hemodynamic stability and stable hemoglobin
• Imaging findings alone do not dictate intervention

Do not delay intervention if clinical deterioration occurs 1

• Unstable patients require immediate surgical exploration, not additional imaging 1

Do not forget long-term ulcer surveillance 1, 4

• Recurrent marginal ulcers occur in 57% of patients after surgical revision 1, 4
• Regular endoscopic monitoring is essential 1, 4

Summary of Orders

Today:

• CBC with differential
• Continue abdominal binder
• Serial abdominal exams every 6-8 hours
• Confirm patient is on high-dose PPI therapy

Tomorrow:

• Repeat CBC to confirm stable hemoglobin

Outpatient (within 3 months):

• Schedule upper endoscopy with biopsies for anastomotic surveillance 1, 4
