Purpose: The use of intercostal nerve cryoablation (INC) has been an effective modality for treating pain in patients undergoing pectus excavatum (PE) repair. This study sought to evaluate if PE patients undergoing Nuss procedures with INC and intercostal nerve block (INB) could safely be discharged the same day of surgery., Methods: A prospective study with IRB approval of 15 consecutive patients undergoing PE Nuss repair with INC, INB, and an enhanced recovery after surgery (ERAS) protocol was conducted. The primary outcome measure was hospital length of stay (LOS) in hours. Secondary variables included same day discharge, postoperative complications, emergency department (ED) visits, urgent care (UC) visits, opioid use, and return to the operating room (OR)., Results: LOS averaged 11.9 h amongst 15 patients. Ten patients (66.7%) went home on postoperative day (POD) 0, and the rest went home on POD 1. No patients stayed in the hospital due to pain. Reasons for failure to discharge included urinary retention, drowsiness, vomiting, and anxiety, but not pain. No patients were readmitted to the ED. One patient visited UC for constipation. One patient had bar migration requiring return to the OR for revision. Ten (66.7%) patients did not use opioids after discharge., Conclusions: Same day discharge is feasible and safe in PE patients undergoing Nuss procedure with INC and INB. INC with INB can adequately control pain without significant complications. Same day discharge can be safely considered for PE patients undergoing Nuss procedure with INC with INB., Type of Study: Prognosis study LEVEL-OF-EVIDENCE RATING: Level II., Competing Interests: Declaration of Competing Interest None., (Copyright © 2021 Elsevier Inc.

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., Competing Interests: Conflict of Interest The authors report no conflicts of interest., (Copyright © 2022 Elsevier Inc.

Purpose: Intercostal Nerve Cryoablation (INC) has significantly improved pain control following the Nuss repair of pectus excavatum (PE). This study sought to evaluate patients undergoing the Nuss repair with INC compared to the Nuss repair with an ERAS protocol, INC, and intercostal nerve blocks (INB)., Methods: In June 2020, a new protocol was implemented involving surgery, anesthesia, nursing, physical therapy, and child life with the goal of safe same day discharge for patients undergoing the Nuss repair. They were compared to a control group who underwent the Nuss repair with INC alone in 2017-2019. The primary outcome measure was hospital length of stay (LOS) in hours, secondary outcomes were number of patients discharged on postoperative day (POD) 0, and returns to the emergency department (ED), urgent care (UC), and operating room (OR)., Results: The characteristics between the groups were the same (Table 1). The mean LOS was 11.8 h in the INB group versus 58.2 h in the INC group, p < 0.01. 10 of 15 patients in the INB group went home on POD 0 (average of 5.5 h postop), versus 0 patients in the INC only group, p < 0.01. Five patients in the INB stayed overnight. Two patients stayed owing to anxiety, one owing to urinary retention, one owing to nausea, and one owing to drowsiness. None stayed for pain control. Four patients in the INC group returned to the ED for pain control, versus 0 in the INB group, and 1 patient in the INB returned to UC for constipation., Conclusions: The majority of patients undergoing the Nuss repair of PE with a multidisciplinary regimen of pre and postoperative nursing education, precise intraoperative anesthesia care, performance of direct vision INB and INC, as well as careful surgery can go home on the day of surgery without adverse outcomes or unanticipated returns to the hospital., Level-Of-Evidence: Level II., Competing Interests: Declaration of Competing Interest None., (Copyright © 2021.

Purpose: The use of intercostal nerve cryoablation (INC) is becoming increasingly common in patients undergoing pectus excavatum (PE) repair. This study sought to evaluate the use of INC compared to traditional use of thoracic epidural (TE)., Methods: A retrospective review of 79 patients undergoing PE repair with either INC or TE from May 2009 to December 2019 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 postoperative complications., Results: LOS decreased to 2.5 days in the INC group compared to 5 days in the TE group (p < 0.0001). Surgical time was increased in the INC group, but there was no difference in total OR time. The INC group experienced significantly lower hospital costs. 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., Conclusions: INC is a newer modality that decreases LOS, controls pain, and results in overall cost savings. We recommend that INC be included in the current practice for postoperative pain control in PE patients undergoing Nuss procedure.
