Abstract

BackgroundVisceral pain accounts for nearly 28% of cancer-related pain, and its effective management poses significant challenges. The diverse pathways of neurotransmission, neurotransmitters, channels, and receptors suggest the need for individualized analgesic therapy. Our objective is to explore a therapeutic alternative for managing malignant visceral pain in advanced cancer.CasesIn this report, we present two patients with malignant bowel obstruction and severe visceral pain, despite receiving opioid treatment, necessitating an alternative approach. Surgical interventions were considered but promptly ruled out. Paracentesis was performed as necessary. Pain management was initiated using a combination of opioids and co-analgesics. However, both patients required opioid dose escalation without achieving adequate pain control or tolerating the associated side effects. Consequently, a lidocaine infusion was administered to alleviate pain.OutcomeFollowing 24-48 hours of lidocaine infusion, both patients achieved satisfactory symptom control, enabling a reduction in opioid doses and improvement in intestinal transit. No side effects were reported during the treatment.DiscussionLidocaine infusions may be beneficial for pain management in patients with malignant bowel obstruction and visceral pain. The extent of pain control achieved in comparison to other therapeutics remains challenging to ascertain. We posit that lidocaine infusions, with their potential impact on visceral hypersensitivity, can enhance pain control and facilitate the recovery of bowel transit. Further studies are warranted to validate these findings.
