Abstract
Adequate pain control immediately after esophagostomy is critical to patient recovery and may be compromised by uncertainty regarding correct epidural catheter placement. The aim of the current study was to determine the role of performing an epidurogram in selective patients to assess epidural placement after esophagectomy. Patients undergoing esophagectomy in a high-volume center were retrospectively reviewed to identify those in whom an epidurogram was performed less than 24 hours after surgery. Since 2012 epidurograms have been selectively performed in patients and have demonstrated features concerning for incorrect epidural catheter placement, including difficult/complicated insertion, negative sensory test, nonreassuring intraoperative hemodyamic response, and inadequate postoperative pain control. Fifty-two of 192 patients (27%; 43 men; age 65 ± 11 years) who underwent esophagostomy since 2012 had an epidurogram. Epidurograms were not associated with any adverse events. In 21 patients (40%) epidurogram findings led to a direct change in patient management, prompting either removal/replacement of an incorrectly sited catheter (n= 9), partial withdrawal of a catheter associated with unilateral contrast distribution (n= 2), or by endorsing a clinical decision to modify the analgesic regimen in a patient with a correctly sited epidural catheter (n= 10). Identifying and rescuing incorrect epidural catheter placement was not associated with longer intensive care unit/hospital stay or postoperative morbidity (p > 0.05) CONCLUSIONS: We reviewed selective epidurogram use in esophagectomy patients to determine its role in "rescuing" inadequate pain control through expediting clinical decision-making. Findings confirm that in selected patients epidurography is feasible and has the potential to directly contribute to patient care.
