Effectiveness of fluoroscopy-guided lytic inhibition of splanchnic nerves with phenol at 2 levels versus 1 level in upper abdominal visceral pain
Abstract
Objective: To determine the effectiveness of phenol-based lytic inhibition of the splanchnic nerves at two levels versus one level, guided by fluoroscopy, in patients with upper hemi-abdominal visceral cancer pain.
Materials and Methods: A retrospective, observational, descriptive, cross-sectional study was conducted on patients with upper hemi-abdominal visceral cancer pain treated at the Pain Clinic of the National Cancer Institute, Mexico. Statistical analysis was performed using SPSS V25.0.
Results: Pain reduction was evaluated in 85 patients who underwent INE (65 at one level and 20 at two levels). Most patients experienced a short-term reduction in pain intensity (2 hours and 1 week) assessed using the ENA scale, with a decrease of 1 to 3 points in one-level INE and 2 to 3 points in two-level INE. In the long term, some patients maintained analgesia, with an average reduction of 4 points at one month and 3 points at three months in both groups. Opioid consumption (MED) decreased post-procedure in both groups, with an average reduction of 11.02 mg/day in the one-level INE group and 24.7 mg/day in the two-level INE group. Additionally, patients reported high levels of satisfaction (Likert Scale 4/5 or 5/5).
Conclusions: The procedure is equally effective for patients undergoing one-level or two-level lytic INE. Pain control was greater in the group of patients treated with a two-level approach, as reflected in post-procedure MED, which showed a greater reduction in patients undergoing two-level INE. The satisfaction level was classified as satisfied or very satisfied, indicating that performing this procedure at either one or two levels is useful for controlling visceral cancer pain.
