The most recent procedure for pectus excavatum repair involves crane-powered entire chest wall remodeling, which employs crane lifting, multiple-bar approach, bridge stabilization, and sandwich techniques. This resulted in a paradigm shift in pectus deformity repair from merely lifting the sunken bone to remodeling the chest wall into normal anatomy. We analyzed 649 patients who underwent surgery for pectus excavatum or complex combined deformities between March 2018 and January 2022. A crane with sternal wiring or screwing was used to lift the chest wall without using the pectus bar turning power. Multiple bars with bridge connections were placed to eliminate bar displacement. Modified sandwich techniques were applied to relieve the lower coastal flare (flare-buster) and focal protuberance (magic string). The mean age of the patients included in the study was 12.2 years (range: 3-45 years). A single bar was used for 202 patients until 2021. For the multiple-bar technique, parallel bars (n = 142), crossbars (n = 166), and crossbars plus upper horizontal bars (XI pattern; n = 139) were used. The overall complication rate was 6.2 %. There was no cases of bar displacement were observed, but other minor complications such as pneumothorax (n = 20, 3.1 %), pleural effusion (n = 7, 1.1 %), and wound infection (n = 5, 0.8 %) were detected. Three patients required reoperation (infection, two: hemorrhage, one). The crane-powered entire chest wall remodeling technique improved the safety and comprehensiveness of the repair procedure. By incorporating bridge stabilization and the use of multiple bars, we effectively resolved the issues related to bar displacement and incomplete repair. Retrospective Cohort Study.

Introduction Conventional postoperative pain management, with an intravenous patient-controlled approach or thoracic epidural analgesia, has proved suboptimal following a minimally invasive repair of pectus excavatum. Considering its postulated mechanism of action, we encouraged cryoanalgesia as an effective method for postrepair pain management and a possibly superior alternative. Methods A randomized, single-blind clinical trial was tested on patients undergoing pectus excavatum (PE) repair in March and December 2022. Among 101 patients, consenting study participants were randomly assigned to one of two groups: cryoanalgesia (group C, n = 24) or noncryoanalgesia (group N, n = 24). Group N received conventional pain management. Comparing the results, pain levels were measured using the visual analog scale (VAS-R for resting and VAS-D for dynamic) and the total rescue analgesic consumption was determined. Intrathoracic cryoablation was performed bilaterally on the fourth and seventh intercostal nerves using a cryoprobe at −80°C for 2 minutes. Results The two groups had similar baseline-patient characteristics; however, group C had a longer mean operative time (159 vs. 125 minutes, p < 0.01) and experienced significantly less pain throughout the postoperative course, with VAS at 6 hours (5.38 vs. 7.04, p < 0.01) and 48 hours (3.17 vs. 5.67, p < 0.01). Conclusion Cryoanalgesia improved postoperative pain control at rest and during movement following PE repair. However, the outcome was less favorable than expected because the VAS was greater than 4 (moderate pain), although after a day or two, it decreased to lower levels (VAS < 4) in the cyro group. Considering its extra invasiveness and instrumentation, a routine cryoanalgesia procedure for pectus surgery is yet to be determined.

Background: Effective postoperative pain management following video-assisted thoracoscopic surgery (VATS) lobectomy is essential to optimize recovery and minimize opioid consumption. This study aimed to compare the analgesic efficacy of ultrasound-guided continuous serratus anterior plane block (SAPB), intercostal nerve block (INB), and their combination (SAPB + INB) in patients undergoing VATS lobectomy.Methods: In this single-center, single-blinded, randomized controlled trial, 90 patients undergoing VATS lobectomy for confirmed or suspected lung cancer were randomly assigned to one of three groups: INB (n = 30), continu.ous SAPB (n = 30), or SAPB + INB (n = 30). The primary outcome was postoperative pain assessed using the visual analog scale (VAS) at 24 h. Secondary outcomes included VAS scores at 1, 3, 6, 12, 48, and 72 h postoperatively, cumulative opioid consumption, length of hospital stay, and postoperative complications.Results: No significant differences in VAS scores were observed among the three groups at 24 h postoperatively. All groups maintained acceptable pain levels (VAS < 4) throughout the study. However, opioid consumption was significantly lower in both the SAPB and SAPB + INB groups compared to the INB group at all time points (p < 0.01).Conclusions: Continuous SAPB, INB, and SAPB + INB were all effective for postoperative pain management after VATS lobectomy. However, INB alone was associated with significantly higher opioid use. Given its technical simplicity, prolonged analgesic effect, and opioid-sparing properties, continuous SAPB represents a valuable component of multimodal analgesia in enhanced recovery protocols.
