ObjectivesManaging abdominal pain can be difficult. This is due to the nonspecific nature of the pain, the multiple etiologies, and the different mechanisms underlying this type of pain. Abdominal wall pain in particular poses its own challenges. Traditionally, chronic abdominal wall pain has been managed with nonopioid analgesics, and in severe cases, opioid therapy has been considered. For patients with chronic abdominal wall pain refractory to medication management, peripheral nerve blocks and spinal cord stimulation also have been trialed with some success. In this study, we present a case series in patients with chronic abdominal wall pain who were treated with a multicontact peripheral nerve stimulation (PNS) system in the transversus abdominis plane (TAP).Materials And MethodsThis was a single-center, retrospective case series. Data were included from adults with chronic abdominal wall pain whose symptoms were refractory to standard medical management and who underwent a multicontact PNS system placement in the TAP.ResultsFour patients met the inclusion criteria. All four patients underwent a multicontact PNS trial lead placement in the TAP. One patient reported no benefit from the trial. The remaining three patients underwent a permanent multicontact PNS system placement in the TAP.ConclusionsIn patients with chronic abdominal wall pain whose symptoms are refractory to conservative medical management, PNS may be an alternative treatment option. As the use of PNS for chronic abdominal wall pain and other fascial planes continues to develop, additional research is necessary to determine optimal placements and specific stimulation parameters.Copyright © 2024 International Neuromodulation Society.
