Long-term control of abdominal pain related to POTS: two case reports in pediatrics

To describe two consecutive cases of Postural Orthostatic Tachycardia Syndrome (POTS)-related chronic abdominal pain control in children after bilateral splanchnic block. Two pediatric patients with chronic abdominal pain related to POTS received celiac and T11 splanchnic plexus block for pain control. While celiac plexus block did not provide any substantial relief of their pain, splanchnic block provided a long-term improvement in pain scores, nausea and vomiting cessation. Bilateral T11 splanchnic block should be considered in patients with POTS-related chronic abdominal pain, nausea and vomiting.
