Purpose:
The use of intercostal nerve cryoablation (INC) is becoming increasingly common in patients undergoing pectus repair. This study sought to evaluate the use of INC compared to traditional use of thoracic epidural (TE) in patients undergoing the modified Ravitch procedure.
Methods:
A retrospective review of 37 patients undergoing the modified Ravitch repair with either INC or TE from March 2009 to July 2021 was conducted. The operations were performed by four surgeons who worked together at four different hospitals and have the same standardized practice. The primary outcome measure was hospital length of stay (LOS). Secondary variables included surgical time, total operating room time, operating room time cost, total hospital cost, inpatient opioid use, long term opioid use after discharge, and post-operative complications.
Results:
LOS decreased to 2.8 days in the INC group compared to 6 days in the TE group (p<0.0001). Surgical time and total OR time was increased in the INC group. The INC group experienced significantly lower hospital costs (p<0.01). Total hospital opioid administration was significantly lower in INC group, and there was a significant decrease in long term opioid use in the INC group (p<0.0001).
Conclusions:
INC is a newer modality that decreases LOS, controls pain, and results in overall cost savings for patients undergoing the modified Ravitch procedure. We recommend that INC be included in the current practice for postoperative pain control in pectus disorder patients undergoing the modified Ravitch procedure.
