What are the management and potential complications of multiple surgical clips in the right groin?

Management of Multiple Surgical Clips in the Right Groin

Multiple surgical clips in the right groin typically do not require removal and can be managed with observation unless specific complications develop.

Purpose and Function of Surgical Clips

• Surgical clips are intentionally placed during procedures to mark surgical field boundaries, identify high-risk areas, and serve as guides for potential future treatments 1
• In vascular and oncologic surgeries, clips secure blood vessels, mark tumor beds, and facilitate targeted radiation treatment 1, 2
• Clips are designed to remain in place permanently and generally do not require removal in asymptomatic patients 1

Potential Complications

• Clip migration can occur in rare cases (estimated in 0.1-0.6% of patients with tubal ligation clips), potentially leading to groin hernias, chronic pain, or local inflammation 3, 4
• Infection at clip sites is uncommon but may present with localized pain, erythema, or drainage 5
• Clips can occasionally serve as a nidus for pseudoaneurysm formation following vascular procedures 6
• Foreign body reactions may develop, causing persistent discomfort or palpable masses 4

Management Approach

For Asymptomatic Patients

• Regular clinical monitoring through physical examination is sufficient in most cases 1
• Imaging is not routinely necessary unless symptoms develop 1
• Clips should be left in place as they often serve important marking functions 1

For Symptomatic Patients

• Evaluation is warranted if the patient develops:
  • Pain or discomfort at the clip site 1, 4
  • Signs of infection (erythema, drainage, fever) 5
  • Palpable mass or abnormality at the clip site 1
  • Recurrent hernias in the region 3

Diagnostic Workup for Symptomatic Patients

• CT imaging is recommended to identify clip location and any associated complications such as migration, abscess formation, or hernia 3
• Duplex ultrasound has shown 98% accuracy in diagnosing groin complications following vascular procedures 6

Treatment Options

Conservative Management

• Observation is appropriate for asymptomatic patients or those with mild symptoms 1
• Anti-inflammatory medications may help manage discomfort 4

Surgical Management

• Surgical removal of clips is indicated when:
  • Clips have migrated and are causing symptoms 3, 4
  • There is evidence of infection not responding to antibiotics 5
  • Clips are associated with recurrent hernias 3
  • Clips are causing persistent pain affecting quality of life 4

Endoscopic Management

• For certain complications like gastrointestinal leaks or fistulas related to migrated clips, endoscopic management using over-the-scope clips (OTSC) may be considered 7
• Endoscopic management has shown success rates of up to 83% for treating complications and may prevent the need for more invasive surgery 7

Follow-up Recommendations

• Regular clinical follow-up is advised for patients with known surgical clips 1
• For patients who had oncologic surgery, maintain regular oncologic surveillance as the clips serve as important markers 1
• Patients should be educated about potential symptoms that warrant medical attention 1
• If surgical removal of clips is performed, follow-up should ensure complete resolution of symptoms 3, 4

Special Considerations

• In patients with multiple previous groin surgeries, the risk of complications from clip removal may outweigh benefits 2
• Hemodynamically unstable patients with suspected clip-related complications should undergo immediate surgical exploration rather than endoscopic management 2
• Patients with a history of vascular grafts require careful evaluation as clip-related complications could potentially jeopardize graft integrity 2
