External Oblique Intercostal Plane Block: A Case Report and Review of Literature

Chronic low back pain (CLBP) and post-laminectomy syndrome (PLS) can pose significant therapeutic challenges, often refractory to conservative management. We present a case of a 52-year-old male with refractory CLBP and PLS who underwent spinal cord stimulation (SCS) lead placement, and subsequently developed chronic right anterior chest wall and upper abdominal pain. Despite using SCS and opioid therapy, the pain persisted until an ultrasound-guided external oblique intercostal plane block (EOIPB) was administered, resulting in complete pain relief. This case highlights the efficacy of EOIPB in managing chronic post-surgical neuropathic pain, underscoring its potential as a valuable intervention in such cases.
