Abstract

Meralgia paresthetica (MP) is a neuropathic pain caused by the entrapment of the lateral femoral cutaneous nerve (LFCN). There have been reports of MP following various surgeries; however, it has not yet been reported after hemorrhoid surgery. We report a case of bilateral MP after hemorrhoid surgery in a jack-knife position. The patient presented with pain, tightness, and a tingling sensation in the anterolateral aspect of both thighs. Ultrasonography-guided LFCN block was used for diagnosis and treatment, along with conservative management for 20 days with oral medication. One month later, the patient’s symptoms had resolved completely. MP due to the jack-knife position may occur postoperatively in patients with predisposing risk factors such as obesity and diabetes mellitus, despite adequate padding and a shorter operating time.
