Neurological Complication After Laparoscopic Sleeve Gastrectomy: Foot Drop

Area of Science:

• Bariatric Surgery
• Neurology
• Metabolic Disorders

Background:

• Peroneal nerve entrapment neuropathy (PNEN) has been linked to rapid weight loss post-bariatric surgery.
• The specific incidence and contributing factors of PNEN following laparoscopic sleeve gastrectomy (LSG) require further investigation.

Purpose of the Study:

• To determine the occurrence of PNEN in patients undergoing LSG.
• To identify factors associated with PNEN development after LSG.

Main Methods:

• Retrospective evaluation of 635 patients who underwent LSG.
• Analysis of preoperative data, nutritional status, weight loss, and electromyography (EMG) findings.
• Documentation of neurological symptoms and treatment outcomes.

Main Results:

• Seven out of 635 patients (1.1%) developed foot drop due to PNEN.
• Significant rapid weight loss observed: mean 50.6 kg at 6 months and 63 kg at 12 months.
• No vitamin deficiencies were detected; EMG confirmed PNEN diagnosis.

Conclusions:

• Rapid weight loss is a significant risk factor for developing PNEN and subsequent foot drop after LSG.
• LSG patients experiencing substantial weight loss should be monitored for neurological complications.
