Comparison of Postoperative Period in Patients with Pectus Excavatum Treated with Nuss Technique and Ravitch Technique

Postoperative pain and psychological outcomes following minimally invasive pectus excavatum repair: A report from the Society for Pediatric Anesthesia Improvement Network

BACKGROUND

Minimally invasive repair of pectus excavatum (MIRPE) is associated with less tissue trauma; however, it may result in increased postoperative pain. Pain experience is a known risk factor for the development of posttraumatic stress symptoms, though there are little data on its relationship with long-term psychological outcomes following major surgery in pediatric patients.

AIMS

In this study, we examined the relationship between immediate postoperative pain and psychological outcomes at 2 weeks and three months after discharge in a cohort of pediatric patients who underwent MIRPE. We sought to determine whether immediate postoperative pain levels were associated with ongoing distress related to aspects of surgery at both time points. We were also interested in how psychological symptoms related to persistent pain concerns.

METHODS

Data on patients undergoing MIRPE across 14 institutions were collected as part of the Society for Pediatric Anesthesia Improvement Network (SPAIN). Patients were contacted at 2 weeks and three months following discharge to track pain levels and assess psychological distress using a self-report questionnaire. Patients were grouped into cohorts based on self-report of distress related to aspects of surgery, nonsurgical distress, or absence of distress.

RESULTS

Analysis revealed that a higher proportion of children reporting ongoing distress related to surgery at both 2 weeks and 3 months experienced higher immediate postoperative pain levels. A subset of patients with complete data sets for 2 weeks and 3 months (N = 76) was further examined. Among the 47 patients who endorsed surgical distress at 2 weeks, 25 (53.2%) continued to endorse surgical distress at 3 months. Additionally, report of surgical distress at 3 months was associated with longer-term postoperative pain.

CONCLUSIONS

Our data suggest that, in patients undergoing MIRPE, the presence of distress at 2 weeks and 3 months may be associated with higher immediate postoperative pain levels.

Comparison of the Nuss versus Ravitch procedure for pectus excavatum repair: an updated meta-analysis

BACKGROUND/PURPOSE

To evaluate surgical outcomes of Nuss versus Ravitch repair of pectus excavatum via a systematic review and meta-analysis.

METHODS

Medline, PubMed, Cochrane, EMBASE, and Google Scholar databases were searched up to September 5, 2016 using the following search terms: pectus excavatum, funnel chest, Nuss; Ravitch, minimally invasive, and open surgery. Randomized controlled trials, two-arm prospective, and two-arm retrospective studies were eligible for inclusion.

RESULTS

Nineteen studies were included with a total of 1731 patients: 989 treated with Nuss and 742 treated with Ravitch. The overall analysis revealed that patients in the Nuss group had significantly shorter operation time (pooled SMD=-2.83, 95% CI=-3.76 to -1.90, p<0.001) and less blood loss (pooled SMD=-1.68, 95% CI=-2.28 to -1.09, P<0.001) than the Ravitch group. However, the length of hospital stay was similar between groups (pooled SMD=-0.55, 95% CI=-1.44 to 0.35, p=0.230). These findings were similar in the subgroup analysis for randomized and non-randomized controlled studies. Complications were not assessed due to inconsistent reporting across the included studies.

CONCLUSIONS

Our meta-analysis demonstrate that the Nuss procedure has a shorter operative time and less operative blood loss than the Ravitch procedure while the postoperative length of stay was similar.
