Analyzing Outcomes of Nuss and Ravitch Repair for Primary and Recurrent Pectus Excavatum in Adults.

ABSTRACT

BACKGROUND: Limited data exist for pectus excavatum repair in adults. We reviewed outcomes in adult patients undergoing Ravitch or Nuss pectus excavatum repairs to determine whether there was a statistical difference in postoperative complications and recurrence between primary and redo operations. METHODS: Patients undergoing pectus excavatum repair between 2001 and 2018 were excluded if they were receiving a concurrent unrelated operation, aged younger than 18 years, or had less than 1 year of follow-up (for recurrence analysis). Postoperative complications were recorded based on procedure type (Ravitch/Nuss) and iteration of repair (primary/redo). Continuous patient data were compared using Student t tests for variables such as age, length of stay, estimated blood loss, body mass index, and number of bars inserted. Fisher exact or χ2 tests were performed for postoperative complications and recurrence rates between groups. RESULTS: Of 290 patients, there were no significant differences in postoperative complications or recurrence rates between all Nuss repairs (n = 237; P = .59) and all Ravitch repairs (n = 53; P = .48), redo Nuss repairs (n = 53; P = .26) and Ravitch repairs (n=26; P = .99), and primary (P = .26) and redo Nuss (P = .10) repairs or primary (P = .99) and redo Ravitch (P = .99) repairs. There were significant differences in age, length of stay, follow-up, bars inserted, and estimated blood loss between all Nuss and Ravitch repairs (P < .05). CONCLUSIONS: Postoperative complication and recurrence rates were not statistically different between Nuss and Ravitch procedures of all types, suggesting either procedure may have utility in recurrent pectus excavatum. Further research may look to expand sample size and a prospective study investigating long-term outcomes.
