RESUMEN
Background Pectus excavatum is the most common chest wall deformity. There is still controversy about cardiopulmonary limitations of this disease and benefits of surgical repair. This study evaluates the impact of pectus excavatum on the cardiopulmonary function of adult patients before and after a modified minimally invasive repair. Methods and Results In this retrospective cohort study, an electronic database was used to identify consecutive adult (aged ≥18 years) patients who underwent cardiopulmonary exercise testing before and after primary pectus excavatum repair at Mayo Clinic Arizona from 2011 to 2020. In total, 392 patients underwent preoperative cardiopulmonary exercise testing; abnormal oxygen consumption results were present in 68% of patients. Among them, 130 patients (68% men, mean age, 32.4±10.0 years) had post-repair evaluations. Post-repair tests were performed immediately before bar removal with a mean time between repair and post-repair testing of 3.4±0.7 years (range, 2.5-7.0). A significant improvement in cardiopulmonary outcomes (P<0.001 for all the comparisons) was seen in the post-repair evaluations, including an increase in maximum, and predicted rate of oxygen consumption, oxygen pulse, oxygen consumption at anaerobic threshold, and maximal ventilation. In a subanalysis of 39 patients who also underwent intraoperative transesophageal echocardiography at repair and at bar removal, a significant increase in right ventricle stroke volume was found (P<0.001). Conclusions Consistent improvements in cardiopulmonary function were seen for pectus excavatum adult patients undergoing surgery. These results strongly support the existence of adverse cardiopulmonary consequences from this disease as well as the benefits of surgical repair.

PURPOSE: Upper age limits for bariatric surgery are questioned on the merits of increased complication rates in the elderly and questionable efficacy. This study evaluates outcomes of bariatric surgery in patients ≥ 70 years of age. MATERIALS AND METHODS: Retrospective review was performed of patients ≥ 70 years of age who underwent laparoscopic Roux-en-Y gastric bypass (RYGB) between 2001 and 2018. Primary endpoints were 30-day readmission, Clavien-Dindo grade III-V (CD III-IV) complications, and mortality. Secondary data included were weight loss, long-term outcomes, comorbidity resolution, hemoglobin A1C, and lipid panels. RESULTS: A total of 23 patients with an average age of 72 years (range 70-80 years) and mean BMI of 43.3 (range 37.3-56.0) were reviewed. Average length-of-stay was 2.4 days (range 1-6 days), with the only acute complication being aspiration pneumonia in one patient. Median follow-up was 69.3 weeks (range 9-875 weeks). One-year follow-up rate was 96%, during which no deaths or CD III-IV complications occurred. Subsequently, one patient experienced failure-to-thrive requiring temporary enteral nutrition. Average 1 year percent total weight loss (%TWL) was 29%, and this was maintained on subsequent follow-ups. Average 1 year percent excess weight loss (%EWL) was 60%, maintained long-term at 61%. Significant serum biochemical improvements included hemoglobin A1C (6.9 ± 1.4% to 5.6 ± 1.3%, p = 0.001), triglycerides (155 ± 49 mg/dL to 102 ± 41 mg/dL, p = 0.0003), and high-density lipoprotein cholesterol (48 ± 14 mg/dL to 58 ± 22 mg/dL, p = 0.004). CONCLUSION: Laparoscopic RYGB is a safe and effective treatment for obesity and obesity-related comorbidities in septuagenarians.

The Nuss procedure for repair of pectus excavatum involves the placement of substernal support bars that remain in place for 2 to 3 years. There are concerns about occlusion of the internal mammary artery due to the intrathoracic bars. It would be optimal to preserve one or more internal mammary arteries with the pectus repair. This report describes a 28-year-old man with severe symptomatic pectus excavatum who underwent Nuss repair. Robotic left internal mammary artery takedown was performed at the intercostal spaces planned for Nuss bars to prevent occlusion or damage from the bars.
